Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method and apparatus for boxing bagged products, and more particularly relates to bagged products such as snacks, i.e. The present invention relates to a method and an apparatus for packaging products (hereinafter referred to as bagged products) while arranging them in a partially overlapping state.

[Prior Art and its Problems] When transporting, storing, or trading the above-mentioned bagged products, it is necessary to package a predetermined number of the bagged products and store them in an outer box such as a cardboard box. Conventionally, it has been widely practiced to package bagged products in cardboard boxes, etc., but when the bagged products are flexible packaging products as described above, the following problems remain. Therefore, the current situation is that no method or device that is satisfactory from the viewpoint of product protection has yet been developed.

In other words, snack foods such as potato chips, popcorn, and corn snacks generally have properties such as breakability, hygroscopicity, and scattering of flavor. There's a problem. In particular, there were many problems in terms of breakage. In other words, the above-mentioned snack foods are generally irregular in shape, have severe irregularities, and have a large surface area, so they may be damaged or damaged during the time from when the product is shipped from the factory until it reaches the consumer through various distribution channels. Problems such as a significant drop in value are likely to occur. In order to prevent such troubles from occurring, a method is used in which a predetermined amount of air, nitrogen gas, etc. is sealed in the bag together with the product when the product is packed in a bag. However, when air or gas is sealed in a bag along with a product, and the bag is inflated like a balloon and then packed into a box, the only way to do this is by manually overlapping the bags. . In addition, products packaged in pneumatic packaging or gas packaging as mentioned above,
As the temperature of the product decreases after it is packed into a bag, the bag gradually contracts and its bulk becomes smaller. Furthermore, the air or gas sealed in the bag cannot be prevented from gradually escaping during the distribution process, depending on the sealing properties of the bag itself.

Considering these circumstances, once packed in a box, the bulk of the bag gradually shrinks inside the box, and even bagged items that were initially tightly packed become empty inside the box over time. often occurred.

By the way, the device itself for automatically boxing bagged items has been known for a long time, for example, as disclosed in Japanese Unexamined Patent Application Publication No. 1983-1989.
It is disclosed in Japanese Patent No. 134105 or Japanese Patent No. 60-23105. However, the former device is inefficient in terms of processing a large number of items at once, as it uses a belt conveyor to put the bagged items into the box one by one so that some of the items overlap. It was not suitable for high-speed processing.

Additionally, the device was developed as a device for boxing relatively heavy bagged items such as boiled udon and soba noodles.
It is not suitable for packaging equipment for soft packaging products such as those mentioned above. This is because soft packaging products are lightweight, so even if you try to drop them into a fixed position, they tend to float due to air resistance and other factors, resulting in misalignment.

On the other hand, the latter device uses a drive arm equipped with a vacuum pad to transfer the bagged items supplied via the conveyor to the top of the box while holding them by suction with the arm.
Then, the suction state of the pad is released and the bagged product is dropped into the box.

In this method, if the edge of the packaged item gets caught on the top edge of the box when it is dropped, the item will fall diagonally, so the box itself must be set relatively large. . Therefore, even after the bagged items are stored in the box, there is a problem in that gaps are created between the bagged items.

Due to the actual situation, after the bagged items are stored in the box,
In order to prevent gaps from forming between the bagged items even if the bag itself were to shrink, it was necessary to pack the bagged items as tightly as possible inside the box from the beginning.
Conventional mechanical equipment was unable to pack the items in this manner, and the only option was to rely on manual labor to pack the items into boxes.

Recently, an actuator such as a so-called robot is used, and a suction pad is attached to this actuator, and the suction pad picks up a plurality of bagged items sent on a belt conveyor, and then they are ,
A method has also been proposed in which the actuator is rotated laterally or moved horizontally, and then the actuator is lowered to store the bagged product in an outer case.

However, this method requires the actuator itself to perform three operations intermittently: lifting, suspending, and rotating the bagged product, resulting in extremely slow work speed and poor work efficiency. There was an inconvenience that it was bad.

[Means for Solving the Problems] Here, the present invention provides that when the above-mentioned soft packaging products (bagged products) are packed in an outer box such as a cardboard case, the bagged products are packed from the beginning. When arranging the products so that some of them overlap each other and storing them in the outer box, the multiple bagged products that are arranged horizontally with some parts overlapping are placed on top through a push plate. The bagged items are forced into the box by being pushed down from above, and inside the box, a support plate that can be raised and lowered is placed on standby to support the bagged items pushed in from above and move them toward the box. It was designed so that it could be placed in the receiver gently, so that it would not receive any shock when it falls.

In addition, in the present invention, a plurality of bagged products arranged horizontally in an overlapping state are directly gripped via a suction pad that can be raised and lowered and moved horizontally, and the bagged products are held in an open state while being gripped. The device includes a device that releases the suction state of the suction pad when the suction pad is placed close to the placement surface in the box when the suction pad is directly inserted into the box, and thereby the support plate, which can be raised and lowered as described above, is This makes it unnecessary to use it. As described above, when storing the bagged product in the box, even if the edge of the bagged product comes into contact with the top edge of the box, the bagged product is neatly placed inside the box without being affected by this. It is designed so that it can be stored in.

That is, in the method of boxing bagged products according to the present invention, first, the bagged products are arranged in multiple rows in the direction of travel, and then simultaneously sucked by suction cups, the bagged products are After the items are suctioned so as to be slightly tilted and converged toward the center, and the adjacent bagged items are conveyed to the top surface of the outer box while partially overlapping each other, This item is stored in a box.

Furthermore, the present invention includes a method and apparatus for rearranging the bagged products transferred in a single row into multiple rows during the transfer, and also includes a method and an apparatus for rearranging the packaged products transferred in a single row into multiple rows, and also includes a method and an apparatus for rearranging the packaged products transferred in a single row into multiple rows, and also includes a method and an apparatus for rearranging the packaged products transported in a single row into multiple rows. The attachment is intended to provide a method and apparatus for facing each other.

As mentioned above, the first object of the present invention is to enable flexible packaging products such as pneumatic packaging or gas packaging to be tightly packed in an outer box so that some of the products overlap. At the point. The second purpose is to maintain the state in which the bagged items are tightly gathered together, even if the bagged items gradually deflate and become smaller due to gas leakage after being stored in the box. The point is that there are no gaps between the packed items. The third purpose is to make it possible to pack a large amount of bagged items into outer boxes in a short period of time by operating at a higher speed than conventional mechanical equipment while still being able to pack boxes under the conditions described above. This is what it was intended to do.

[Embodiments] Hereinafter, embodiments of the present invention will be specifically described based on the accompanying drawings. Figures 1A and 1B show an example of a packaged product, in which snacks 2 are packed inside a highly flexible bag 1 made of a material with high gas barrier properties, such as a plastic film coated with aluminum. , and when the bag is packed, air 3 is simultaneously enclosed in the bag. Let the length of this bag 1 be 1, and let the length of the cardboard box that is the outer case when this bag is stored in the outer box be L.

In the present invention, for example, three bagged products S are arranged horizontally and put into the case 4 in a state where they are shaped slightly into each other, and these are placed in a second bag.
As shown in Figure A, they are stored in multiple stacks in the vertical direction.

Incidentally, in the conventional device, as shown in FIG. 2B, the bagged products S are stored in the case with gaps between each other (in a sparse state), or as shown in FIG. 2C. Thus, when dropping the bagged product into the case, there is a problem in that the end of the bagged product comes into contact with the upper edge of the case, causing the bag to become disordered. In this way, when three bagged products are packed horizontally in a case, the dimensional relationship between the case and the bagged products is L'> 3f in the conventional type. The invention has made it possible to properly maintain this relationship in 31.

Therefore, according to the present invention, the size of the box itself in which the bagged items are packed can be made smaller than that of the conventional type.

In other words, since the box of FIG. 2A can be smaller in unfolded dimensions than the box of FIG. 2B, the cost of materials can be reduced accordingly.

3A and 3B are schematic diagrams for generally explaining the method of the present invention and the apparatus for carrying out the method. The bagged products (hereinafter also referred to as articles S) supplied in one row are guided to a double rowing device indicated by the symbol t2, and the single rows are rearranged into three rows, and then they are transferred to the next stage aggregation device t3. The articles in the plurality of rows are brought together so that some of the articles overlap each other.At the article discharge end of the aggregating device, there are articles not shown in FIGS. 3A and 3B. Dropping device 14 (7th A-7
(see Fig. D and Figs. 8A to 8E) is provided, and this device 14 presses down the horizontally overlapping articles from above and forcefully stores them in the cardboard case 4, which is an exterior case. . As described later, a support plate that supports the stored items from the bottom side is waiting inside the outer case, and this plate is placed at the height of the items in the case.

The support height is changed accordingly. In addition, there is a pad that stores the bagged products directly in a box with a closed bottom without using the support plate as described above, and also suctions and grips the bagged products according to the height of the accumulated bagged products in the box. Regarding the device in which the vertical movement of the
-8E) disclosed herein.

In addition, as shown in FIG. 3B, each of the above-mentioned devices includes an automatic case assembly device 15, and a case transfer device 16 that sequentially moves the cardboard cases in the middle of assembly to directly below the article dropping device. Incorporate. 3rd A~3
In Figure B, the reference numeral 4a indicates a cardboard sheet in which the case is folded and stacked, and the reference numeral 4b indicates a state in which the lid of the case is closed after an article has been stored in the case.

In addition, the code attached to the cardboard case after assembly is 4C.
Let me explain based on the diagram. As shown in the figure, out of the four flaps projecting upward from the case, number 4 is
C refers to a flap arranged perpendicularly to the traveling direction, and refers to the upper dust flap, and the flap adjacent to this flap, that is, the flap arranged parallel to the traveling direction, is named the upper side flap 4d. Similarly, among the flaps projecting downward, the flap perpendicular to the traveling direction is referred to as a lower dust flap 4e, and the flap parallel to the direction of travel is referred to as a lower side flap 4r.

The details of each of the above-mentioned devices will be described below with reference to the accompanying drawings.

As mentioned above, the present invention is directed to a series of methods and devices for storing a large number of bagged items in a cardboard case, which is an outer box. Then, the device i6 that transfers the cardboard cases in the middle of assembly will be briefly described, and then the article double-row device 12 connected to the belt conveyor 11, the aggregation device 13, and the article dropping device 14 will be explained in that order. I'm going to go.

[Cardboard case assembly machine] As clearly shown in FIG. 3B and FIGS. 4A to 4B,
A large number of corrugated cardboard sheets 4a, which have been stretched and folded flat, are pulled out one by one from the magazine 30 in the direction of the arrow through the reciprocating vacuum pad 31, and at the same time the guide 32.3'il, Using the guide rail 34 as a guide, the flat sheet is changed from a parallelogram shape to a rectangular cylinder shape as shown by the dashed line in the figure, and then transferred to the assembly machine e and the adjacent case transfer device. It will be introduced on the 16th.

Reference numeral 35 indicates a pushing piece that sequentially pushes out the flat sheet 4a stored in the magazine 30 in the direction of the arrow, and this piece is connected to the drive chain 36 which is suspended from the sprockets 36a and 38b. Meanwhile, the plurality of sheets 4a are mounted on caterpillars 37 that move in conjunction with the chino. In this way, the sheets 4a are taken out from the sheet magazine 30 in L sheets at a time by the sheet 31i. At this time, the sheet 4a is raised by the guides 32, 33, etc., and becomes a rectangular cylindrical exterior case.

The form of the case 4 assembled as described above is as shown in FIG. 4B, and each of the upper and lower flaps of the case is maintained in an open state facing vertically.However, When this case is transferred from the assembly machine 15 to the next stage transfer device 1B, it changes to the state shown in FIG. 4C.

That is, among the lower flaps in the case, the lower side flap 4r remains oriented in the vertical direction, but only the lower dust flap 4e is moved by the action of the guide rail 40.40 attached to the transfer device. Both the front and rear flaps maintain a bent state toward the right in the figure, and proceed toward the left in the figure within the case transfer device 16 at the next stage.

In other words, the lower dust flap is bent to the right by the action of the bottom rail 40 in the device 16. In this way, the open case is guided by the transfer device directly below the article dropping device (4) to be described later.

In addition, in the present invention, when assembling the box, the fourth
Instead of going through the folding process as shown in Figure C, only the bottom of the cardboard box is closed in advance according to the normal folding method, and the fourth
After forming the form as shown in Fig. D, the article is transferred to the article dropping device 1 via a commonly used belt conveyor or the like.
It is also possible to make it lead to 4.

L Case Transfer Device Hereinafter, the process of transferring each flap of the cardboard case while being sequentially folded will be explained mainly based on FIGS. 5A to 5D.

The general structure of this device is a drive mechanism (see Figures 5A and 5B) that drives the assembled rectangular cylindrical cardboard case 4 in order to send it to the left, and a feeding surface mechanism (see Figures 5A and 5B) that slides the case. (see FIG. 5C), and a plurality of drive devices are disposed on both sides of the feed surface mechanism as described later. That is, as clearly shown in FIG. 5A, there are drive devices at several locations on both sides of the transfer device i6 that pull the rectangular cylindrical cardboard case forward via vacuum pads or push it from the rear. (Code 4
1 to 42) are provided, and the case 4 guided to the upper surface of the bottom rail 40 is sequentially extended forward by these drive devices. The drive device is
All of them, except for the one designated by numeral 42, are configured to be movable along the longitudinal direction of the device, and only the one designated by numeral 42 is installed in a fixed position, so that it does not move in the front-back direction either. It has become. That is, the drive device designated by the reference numeral 41 consists of a rodless cylinder 48 disposed parallel to the longitudinal direction of the transfer device, and a rotation mechanism fixed on the piston table of the cylinder 43, and the rotation mechanism is , as shown in FIG. 5B, the rack 41a pinion 4
1b and a rotating arm 41c driven by the pinion 41b.

Note that among the above-mentioned rotating mechanisms, there is one in which a suction pad 44 is attached to the working end of the rotating arm 41c, and this is located at the far right side in FIG. 5A.

The overall structure of how the plurality of drive devices are arranged is as shown in FIG. 5A, and all of them are movable in the longitudinal direction of the device, except for one which is fixed. That is, the rotating arm 41c attached to the upper part of the rodless cylinder 43 is configured to reciprocate in the left-right direction in the figure along the longitudinal direction of the cylinder. In addition, each of the above-mentioned rotating arms 41c or 42c makes a 1/4 rotation around the pinion pongee as shown by the arrow in the figure to send the case forward, and when the feeding is finished, it returns to the initial position. It will be reset.

Incidentally, the reference numeral 44 is a brake cylinder device provided midway along the transfer route, and is for fixing the case at a fixed position at one point during the transfer. Also, the 5th C
As shown in Figures 5D to 5D, a support plate 45 that can be raised and lowered is attached to the end of the bottom rail 40 and enters the rectangular cylindrical case 4 from below. Mechanism 4B is attached.

Proceeding to explain the functions of each drive device, the rectangular cylindrical case at the time of assembly first has a symbol 44 at the rightmost end in FIG. 5A.
It is pulled out to the upper surface of the bottom rail 40, 40 by the rodless cylinder 43 while being attracted to the rotating mechanism 41 with the suction pad shown in . Suction pad 4
4 moves by a predetermined stroke on the cylinder. Then, the rotating arm 41c equipped with the pad 44
rotates as shown by the arrow (dashed line) in the figure and performs a retracting operation to open a passage for the case. Then, another drive device (see drive device 41 drawn in chain lines at the bottom of FIG. 5A) is activated and acts to push the case from the rear to the front. In this way, the rectangular cylindrical case 4 has been pulled out to the top surface of the bottom rail 40 by the suction pad 44.
reaches the position indicated by the symbol X in FIG. 5A. When the case reaches this position Grasp it firmly from the front and back as if you were trying to hit it. (As shown in Figures 5C to 5D, a support plate 45 is waiting at the gripped position The cylinder mechanism 4B is a cylinder mechanism that can be stopped in multiple stages, and in the illustrated example, it operates so as to sequentially change the height of the support plate 45 to five stages. In this way, the article S, which is a bagged product, is placed on the upper surface of the support plate 45, and as the number of loading stages increases, the plate is intermittently lowered via the lock cylinder mechanism 4B, and the article is placed inside the case. As will be explained later, when the articles are stacked in five stages on the support plate 45 as described above, the plate 45 is pulled out from the case 4 and placed in the lowest position. The same height as the bottom rail 40 is maintained.

The above is an embodiment in which the corrugated pole case 4, which is folded into a sheet shape, is assembled into a rectangular cylindrical case, and the case is moved to the article storage position (x) with the case open. be.

The above explanation describes the process of transporting the cardboard case 4 while folding it into the form shown in FIG. 4C.
If the cardboard case 4 is assembled as shown in FIG. 4D, the mechanisms shown in FIGS. 5C-5D may not be used, and as a result, only the mechanisms shown in FIGS. 5A-5B may be used. Therefore, the explanation based on FIGS. 5A and 5B also applies to the case of the cardboard case 4 assembled as shown in FIG. 4D.

Therefore, next, the process of transferring the bagged items to the storage position will be explained.

[Double rowing device for articles] As already mentioned, the present invention collects three packed products side by side, with some of them overlapping each other, and then packages them one by one in stages. It is characterized by being accumulated inside the case. Therefore, it is not possible to apply the above-described present invention after rearranging the bagged products S sent in a single row into multiple rows, or to apply it to the bagged products S sent in advance in multiple rows. However, in the following, as an example of implementing the present invention, the case of bagged products S transported in the - row will be described.
A specific example of a multi-row device that rearranges 3 rows of rows will be explained.

In FIG. 3B, 1. The device indicated by the reference numeral 12 is a double-rowing device for articles, and a normal belt conveyor 11 is placed in front of the device, and bagged products are supplied one by one to the double-rowing device 12 via the conveyor. .

The specific configuration of the double-rowing device is as shown in FIGS. 6A to 6D. First, the concept will be explained with reference to FIG. 6A. One row of articles S transported from left to right is , 50 are introduced into the apparatus, and then the plurality of rows of articles are aligned in a horizontal line by an accumulation stopper 5t.

That is, the sorting device has a support shaft 50a provided on the entrance side of the article, two strip-shaped distribution plates 50b, 50b, and these two sheets rotatably pivoted via the support shaft. The distribution consists of a connecting rod 50c that connects the plates together, and 2
The distribution of the plates into strips simultaneously causes the plates to move as follows.

The first is to guide the flow of the articles without moving the plate to the left or right so that the articles are transported straight and in a straight line. , the above-mentioned sorting is to move the board to either the left or right, thereby guiding the goods sent in one line to be distributed to the left or right in the width direction, and these three steps are performed. By alternating the movements, the distribution of the articles conveyed in one row is changed among the three rows. The articles thus distributed in three rows then pass through the accumulation stopper 5.
After they are temporarily stored in the storage unit 1, they are introduced into the next stage aggregation device in a state where three rows are lined up in a horizontal line.

FIGS. 6B to 60 show details of the double-row device, in which the distribution plate 50b is moved to each of the three positions, ie, the center, right, and left positions, by a drive device designated by the reference numeral 50e. The mechanism is explained below.

The above-described distribution device 50 is mounted on the upper surface of the frame 50d shown in FIG. 6B. This device consists of two air cylinders (one is an air cylinder 50e fixed on the frame) arranged perpendicularly to the direction in which the article travels;
The other one is an air cylinder 50 that is movable with respect to the frame.
f), slide frames 52a and 52b that guide the movement of the movable cylinder 50f and a sliding frame 58 (described later), and a sliding frame 53 fixed to the working end of the piston rod in the cylinder 50e. The connecting rod 50c is movably attached through a long hole 5ta provided in the moving frame. By the way, the above distribution is on the boards 50b, 50b.
One end is pivotally attached to the support shaft 50a attached to the frame 50d as described above, while the other end is attached to the movable shaft 50g connected to the above-mentioned connecting rod 50c.

Then, as the sliding frame 53 moves, the connecting rod moves alternately through three points, the center position and either left or right position, and temporarily stops. , 50b also repeated the same movement,
Sorting out the items.

In addition, all of the above-mentioned parts are mounted on the upper surface of a wide belt conveyor 54, as shown in FIGS. 6B to 60.

In addition, in the front of the device 50, there are four partition walls 5 for the distribution.
The two partitions 5 are formed with an installation width corresponding to the interval between the plates, and an accumulation stopper 5t is provided at the front end of the partition wall to temporarily store the articles transferred from upstream. . The stopper consists of a stop plate 51b pivotably connected to the stop plate 51a so as to be openable and closable, a cylinder 56 for opening and closing the stop plate, and an inspection rod 5Ld for detecting whether three items are aligned at the stop plate. and the stop plate is configured to include:
Limit switch LS-1-L attached to the top of the inspection rod
It is configured to open and close according to the detection signal of S-3.

The apparatus then operates as follows to rearrange the articles supplied in one row into three rows. That is, the articles S conveyed in a single line by the belt conveyor 11 are guided by the guide 56 on the entrance side, and the two articles are sorted by the plate 50b.
, 50b. The distribution plate operates intermittently by the action of the cylinders 50e, 50f, etc., which are the drive mechanisms described above, and is first moved to either the left or right side position, then to the center position shown by the solid line in the figure, and then to the remaining positions. The position is sequentially switched to three stages, such as the lateral position.
The incoming goods are divided into three columns.

This operation first causes the second movable cylinder 50e attached to the piston rod of the first fixed cylinder 50f to slide, and then the sliding frame fixed to the piston rod of this movable cylinder 50e slides. 53 in the width direction of the conveyor along the slide frame 52b,
The continuous rod 50c is thereby attached to the long hole of the frame 53.
is operated in the left-right direction to perform the predetermined operations as described above.

As is clear from the above explanation, the items sorted into three rows are not all lined up horizontally at once, so there is storage in front of the partition wall to keep them lined up. A stopper 51 is provided, and the three shortening rods 5 (d) and limit switch LS-1 in this stopper are
- When it is detected by LS-3 that all the articles in all rows have arrived at the stop bar, the cylinder 5B is actuated in response to the signal, the stopper is released, and the articles in three rows are placed on the belt all at once. It is discharged from the conveyor 54.

As will be explained below, the articles discharged from the conveyor 54 are supplied onto a lifter 57 waiting at the next stage, and transferred to an article aggregation device to be described later via this lifter. As shown in FIG. 6C, the lifter 57 is composed of an elevating tray 57a with a vertical section disposed at the end of the belt conveyor 54, and a cylinder 57b supporting this tray so that it can be moved up and down. ing. When the tray 57a is empty, it waits at the same level at the discharge end of the belt conveyor 54, and when an article is supplied therein, a signal is emitted by a sensor (not shown). Based on this signal, the elevating tray 57a is raised as shown by the chain line in the figure, and is transferred to vacuum pads 62 to 64, which will be described later.

[Article aggregation device] The articles transferred to the upper surface of the elevating tray 57a are
While being picked up and suspended via a vacuum pad that constitutes a part of the article aggregation device shown in Figures A to 70, articles located on both sides are pulled toward the center. , and are aggregated so that some of them overlap. This point will be specifically explained below. In the figure, reference numeral 80 is a frame of the aggregation device, and 6t is a sliding guide rod movably installed on the frame 60.
0 in the width direction of the frame, and is attached so as to be able to slide along the traveling direction of the article as described later. Reference numerals 62 to 64 are vacuum pad mechanisms for sucking and gripping each of the articles, and are movable on the sliding guide rod 61 in a direction perpendicular to the traveling direction of the articles. . As shown in FIG. 7E, this vacuum pad mechanism includes, for example, two front and rear suction tubes 82a and 82b attached so as to straddle the sliding guide rod 61, and these suction tubes are connected to the guide rod. The roller bearing 65 is configured to be slidable along the longitudinal direction of the roller bearing 61. Incidentally, this suction tube can be either one at the front or the rear, and the number of suction tubes can be set freely. In addition, suction pads are attached to the tips of the suction tubes, and the pads directly contact the article S to perform predetermined lifting and lowering operations.
As shown.

As shown in FIG. 7A, the sliding guide rod 6i is installed on two left and right guide rails 67 provided along the direction of movement of the article via a support stand 66.
One of the supports is connected to a piston wood 68a of an air cylinder 68 fixed to the frame 60. When the working cylinder 68 is activated, it is configured to reciprocate on the left and right guide rails 67 in parallel to the traveling direction of the article. On the other hand, as described above, three individually movable vacuum pad mechanisms 62 to 64 are attached to the sliding guide rod 61 so as to be able to slide along the longitudinal direction of the rod 6t. .

Of the three vacuum pad mechanisms 62 to 64 provided with vacuum pads, the vacuum mechanism 63 located in the center is fixed to the sliding guide rod 61, while The attached vacuum mechanisms 62 and 64 are both slidable along the longitudinal direction of the sliding guide rod 61. The support stand 6B supporting the vacuum mechanisms on both sides is configured to be movable in the direction of movement of the article via the guide rail B7. A roller 69 is projected from the lower surface of the mechanism 62 (the same applies to the vacuum mechanism 64), and this roller is attached to a planar triangular cam follower 70 fixed to the frame BO at a position inside the guide rail 67. A spring 71 that is in contact with the vacuum mechanism and always pulls the vacuum mechanism laterally is connected to the vacuum mechanism 62, 64 on both sides and the support base 6 as shown in FIGS. 7A to 7C.
Place it between B and B. and the vacuum mechanism 6
2. For any of 64, always use this as the sliding guide rod 6.
Make sure that the force is acting in the outward direction along line 1. When the vacuum mechanisms 82, 64 slide in the front-rear direction (direction of movement of the article) due to the action of the cylinder 68, the vacuum mechanisms 82, 64 on both sides are guided by the cam follower 70 and moved to the center. It operates in such a way that it moves towards you (when the vacuum mechanism moves forward) or moves away from you to the side (also when it moves backward). Further, when the vacuum mechanisms 62 to 64 are in the most advanced position (the position shown in FIG. 7A), an article dropping device i4 as shown in FIG. 7D is provided so as to overlap that position.

By the way, as the lifter is lifted by the action of the cylinder 57b, the articles transferred to the upper surface of the lifter 57 are moved to the vacuum mechanisms 62 to 64 waiting directly above the lifter as shown by the chain line in FIG. 7D. comes into contact with the pad of the suction tube attached to the. Incidentally, a stopper 51 is provided on the front surface of the lifter to keep the position of the article S constant.
b is fixed, and at that position, the three articles are brought into contact with the pad of the vacuum mechanism by a lifter in a side-by-side alignment. That is, since each of the above-mentioned vacuum mechanisms connected to the vacuum pump has started suction, it is attracted to the pad at the moment of contact, and while maintaining the suction state, the cylinder 68 on the frame is moved as described above. moves forward due to the action of
Moreover, while moving forward, the vacuum mechanisms 82 and 84 located on both sides, as described above,
It is brought to the center by the action of the cam follower 70,
It performs a so-called centering action. By the way, article S
When suspending objects by suction, by adjusting their position so that they are offset from the center, it is possible to adjust the amount of overlap between the objects after centering according to the amount of deviation.

When the centering at the position shown in FIG. 7A is completed in the above manner, the article dropping device shown at 14 in FIG. It is waiting in the completed upper position and operates as follows to store the article in the case.

Hereinafter, the second embodiment regarding the article aggregation device will be described in Sections 8A to 8.
This will be explained in detail based on Figure B. In this embodiment, a corrugated table 100 that can be raised and lowered is arranged on the exit side (discharge end side) of the belt conveyor 54 shown in FIG. Bagged items lined up in a horizontal line are transferred. That is, as shown in FIG. 8B, on the top surface of the table 100, pillow plates 101 (three pillow plates in the illustrated example) corresponding to the number of bagged products to be sent out are tilted diagonally. Since it is attached, all the bagged items placed on the table surface are automatically tilted in a certain direction along the pillow board. An air cylinder 102 for raising and lowering the table is disposed on the underside of the table (00), and guide rods 103, 1 are provided on both sides of the cylinder 102.
03 is installed. Further, the table 100
An edge plate 104 having an L-shaped planar shape is formed protruding from the upper edge of the table to prevent the packaged product S placed on the table surface from falling off. Furthermore, position sensors 105 such as phototubes are installed slightly above the table on both sides to detect when the table has risen to a predetermined position.

On the other hand, above the corrugated table 100, as shown in FIG. 8B, a suction pad 110 is provided that transfers the packaged product S placed on the table surface while suctioning it. The structure and function of this suction pad will be described in detail later, but what is important here is that the suction pad 110 is
It is placed at a position that is slightly biased to one side of the center line C of the bagged product S, to be more precise, it is located at a position that is biased toward the higher side of the diagonal pillow board on the table surface (on the chain line C' in Figure 8B). That's what I did. Under such a configuration, when the bagged product S is transferred onto the corrugated table 100 via the conveyor 54, the bagged product S will not move on the table because the pillow plate 104 is tilted. It will be placed diagonally accordingly. On the other hand, since a position sensor 105 is waiting above the table, it is confirmed that there is a packaged product on the table surface, and a confirmation signal is sent to the table 105.
0 is lifted upward by the operation of the air cylinder 102. Above the table 100, the suction pad 110 is waiting while maintaining the suction state as described above, so that the bagged product S comes into contact with the suction pad and the suction action of the suction pad 110 is on standby. The bagged items are attracted to the pad 110 by the pad 110.

As mentioned above, the line of action C' in the vertical direction of this suction rod is offset from the center line C of the bagged product, so
The suctioned bagged products are naturally held in a tilted state, and at the same time, the bagged products are transferred to the next step, the boxing step, in a mutually overlapping state.

As mentioned above, if the apparatus shown in FIGS. 8A and 8B is used,
Compared to the device of the embodiment described with reference to FIGS. 7A to 7H, the mechanical construction is simpler, and moreover, the time required to partially overlap a plurality of bagged products with each other can be shortened.

[Article dropping device] That is, as shown in FIGS. 7D and 7G, each suction tube (for example, 6
2a, 62b, etc.) is moved to the most forward position, and an article dropping device is attached thereto. It consists of a pressing piece 72 made of
As shown in FIG. 7G, the pressing piece is provided with a notch 73 into which each of the suction tubes attached to the vacuum mechanisms 62 to 64 can fit. Further, the reference numeral 72g is a cushioning rubber attached to the surface that comes into contact with the article, and was attached to prevent the internal article from being damaged when the article is pushed in, but it is not necessarily necessary. Also, the seventh
A configuration as shown in Figure H may be used, and a spring 72b may be compressed between the drop-in plate 76 on the side that contacts the article and the holding piece 72 to serve as a buffer.

Incidentally, the reference numeral 75 is a guide rod for the cylinder.

Thus, the holding piece 72 presses down from above the article adsorbed on each pad of the vacuum mechanisms 62 to 64 by the action of the cylinder 74, and pulls it away from the pad, and places it directly below it. It is then pushed into the rectangular cylindrical case 4. At this time, it goes without saying that the suction state of the tip of the pad is released simultaneously with the downward movement of the holding piece 72 by an electric signal.

The above is the process of gathering three items in the center and storing them in a case with their parts overlapping each other. The support plate 45 shown in the figure has been raised, and the article S is forcibly stored on this plate via the holding piece 72.

[Process of Storing Articles in the Case] While the articles rearranged in three rows as described above move forward while being suspended by the suction holes (rads) in the vacuum mechanisms 62 to 84, The articles are pulled together and brought into close contact with each other, and in some cases, a portion of the articles overlaps as necessary.According to the present invention, it is possible to adjust the position at which the articles are hung and when pulling the suspended articles together. Since the amount of attraction can be freely set, it is possible to obtain the most appropriate degree of closeness depending on the type, weight, size, etc. of the article.

By the way, as shown in FIG. 7D, the position where the article is dropped into the exterior case 4 by the action of the holding piece 72 is the X position explained based on the above-mentioned FIGS. 5C to 5D. The following is an illustration of the process by which the article is stored in the case at this position (1) to (1) in Figure 9A.
6), when the article is centered directly above the outer case 4, the support plate 45 is raised from below within the case 4, so that
As is clear from (4), the article is forcibly pushed into the case onto this plate surface by the pressing piece 72 from above. When the first stage of articles in the height direction is stored in the case in this way, the support plate is successively lowered by the action of the stepping air cylinder 4B (which may also be a lock cylinder) attached to the lower part of the support plate. To go. In this way, when the three items on the second tier overlap the first tier, the plate further descends, and the items are gradually accumulated.

[Closing operation of the outer case] When a predetermined number of articles have been stored in the case 4 as described above, the drive device 41 mounted on the rodless cylinder 43 mounted on the upper left side of FIG. 5A is activated. The rotating arm 41a operates, and until then, the case, which has been fixed at the (X) position, moves as shown in the chain line by the rotating arm 42a of the position-fixed drive device 42 disposed at the bottom of the figure. As it is released, the case is pushed to the left in the figure, transporting it to the position marked (y). (y
) position, the above-described brake cylinder 44 operates to fix the sent case 4 at this position,
Then, the operation of closing the lower flap of the case 4 is performed as described later. That is, the support plate 4
5 emerges from the bottom of the case and is maintained at the level of the bottom rail 40 as described above.

In such a case, among the four lower flaps extending from the lower end of the case, the dust flap 4e located perpendicular to the direction of travel is bent in the following manner. As mentioned above, the case 4 is transferred to the left in FIGS. 5A to 5D, and at this time, of the two dust flaps disposed perpendicular to the direction of movement of the case, the front dust flap is attached to the support plate. 45 from the inside of the case 4, it will be folded at right angles on the inside as shown by the chain line in the figure, so only the remaining rear dust flap needs to be folded back in the opposite direction.

This folding operation will be explained below.

That is, in the embodiment shown in FIGS. 7A to 7H and FIGS. 10 to 12, as shown in FIGS. 5C to 5D, a guide plate 8o is provided at a position adjacent to the support plate 45, and the guide plate 8o is provided at a position adjacent to the support plate 45. A sliding guide plate 8I, which uses the cylinder 81a as a driving source, is attached so that it partially overlaps the back side. Also, a sliding adjustment plate 82 similar to that described above is provided at the rear of the guide plate 8i, and this is connected to the cylinder 8.
2a so that it can be driven. Further, a support plate 83 is attached to cover the sliding adjustment plate 82 so that the adjustment plate 82 can move in and out from below the support plate 83. On the other hand, the guide plate 81 and the adjustment plate 8
Guide plates 81 facing each other at positions between 2 and 2.
When the adjustment plate 82 and the adjustment plate 82 are both in the retracted state as shown by the dotted arrow in FIG.
The structure should be such that it pops out. That is, while attaching the cylinder 84a to the frame 85,
A flap folding arm 8 is attached to the piston rod 84b of the cylinder.
4c is related.

Note that a device for folding in the upper rear dust flap 4C of the outer case 4 is also incorporated in the same configuration as above, and for this, please refer to the upper cover 86 in FIG. 10.

By the way, the case 4 has a driving device 4 shown in FIG. 5A.
1 and the rodless cylinder 43, etc., from the right to the left. During the transfer,
The lower rear dust flap of the case 4 is folded in as follows. First of all, the front dust flap.
As the case 4 moves, the flap maintains its correct folded state, with a guide plate 80 fixed in position, a guide plate 81 in a protruding state, and an adjustment plate 8 also in a protruding state.
2 and is sent to the left while sliding on the upper surface of the fixed support plate 83. When the flap finishes passing directly above the guide plate 8t and the adjustment plate 82 which are in the protruding state as described above, the guide plate 81 and the adjustment plate 82 move as shown by the dotted line arrows in FIG. 5D and in FIG. As shown, the protruding guide plate 81 and adjustment plate 82 are sequentially retracted inward to form a space between the two plates 81 and 82 in which the lower rear dust flap hangs. . When the rear dust flap 4e hangs down in this way, the folding arm 84c of the kicker 84 aims at it, and by the action of the cylinder 84a built into it, folds the flap 4e forward at high speed. 1O figure (8) ~ 1st O
This is also shown in Figure (4). - Once bent, the flap advances in that state by the guidance of the support plate 83 and the like provided on the lower surface of the case, and the articles in the case are held from beginning to end so that they do not fall out. Similarly to the above, the rear dust flap 4c attached to the upper part of the case is folded in by the upper kicker 88 shown in FIG.

In this way, the two front and rear dust flaps 4Q, 4e attached to both the upper and lower sides of the case 4 are bent in the correct direction, and the dust flaps 4d, 4f' of the case 4 are also bent in the correct direction. They are bent in a predetermined direction and closed during transportation via fixed guide rods 90 to 93 shown in FIG. 12, respectively.

In addition, for sealing, hot melt guns 95.95 are installed at the upper and lower positions in the transfer path of the case.
Gluing is done against the image.

[Another embodiment of the method and device for boxing bagged products] Section 7A
In addition to the embodiments shown in Figures 7B and 1O to 1Z, the present invention can be practiced using the following apparatus. That is, it is also possible to use the apparatus shown in FIGS. 8c to 8E and combine the conveyor apparatus shown in parentheses with the conveyor apparatus shown in FIGS. 5A to 5B, so this point will be explained below.

In FIGS. 8C to 8E, a horizontally extending guide frame 121 is provided above the lifter 57, and the tip of the guide frame 121 is arranged to cover directly above the lifter. A suction pad 122 that reciprocates is attached to this guide frame L21 using a mechanism similar to that shown in FIG. 7E. A reciprocating motion is performed between point X and point Y in the diagram along the longitudinal direction, while
At the point, a transfer plate 124 for transshipment is provided, which has a fixed horizontal position and only moves up and down. As shown in the figure, this transfer plate is supported by a vertical stepping air cylinder (also referred to as a lock cylinder) (25) attached to a guide frame 121 so as to be able to move up and down in the vertical direction.
In this stepping air cylinder 125, the stroke of a piston rod 125a in the cylinder is variable, and the number and mounting position of reed switches (REEDSWITCII) 125b attached to the outer circumference of the cylinder can be adjusted by adjusting the piston rod 125a. The stroke of the rod can be operated in a sequential (stepwise) and periodic manner. In the present invention, by using the above-described stepping air cylinder or lock cylinder 125, the stroke of the piston rod 125a in the cylinder is sequentially (stepwise) and periodically, as explained based on FIG. 9B below. By changing the design, it is possible to stack bagged items in multiple tiers inside the outer case.

By the way, the planar shape of the transfer plate 124 is rake-shaped (globe-shaped) as shown in FIG. Make sure that 122 is included. Also,
A plurality of suction pads 12B different from the suction pad 122 are attached to the lower surface of the transfer plate 124, and these suction pads are attached to the transfer plate 124 in the vertical direction via a small air cylinder 126a attached to the transfer plate. Keep it in such a condition that it can be moved up and down slightly. Then, as shown in FIG. 8C, the bagged product S placed on the lifter 57 is lifted up by a suction pad 122 that reciprocates in the horizontal direction, and is then passed through the pad 122 directly below the transfer plate 124. When the bagged product reaches directly below the transfer plate, the suction pad 126 attached to the transfer plate is operated to cause it to be sucked onto this pad. That is, before the bagged product S comes directly under the transfer plate, the suction pad 12B arranged on the lower surface of the transfer plate is raised slightly upward via a small air cylinder 126a. When the bagged product reaches directly below, the pad 12B is lowered to perform a suction operation while contacting the bagged product. After that,
The suction operation of the suction pad 122, which moves in the horizontal direction, is released and the transported bagged items are transferred to the lower surface of the transfer plate 124.

In this way, the bagged items adsorbed to the lower surface of the transfer plate are now lowered together with the transfer plate as shown by the chain line in FIG. 8C by the action of the stepping air cylinder 125 attached to the transfer plate. , and gently insert it into the exterior cardboard case 4, which opens directly below, to prevent it from falling by itself.

The details are as shown in (1) to (16) in FIG. 9B, and when the packaged product S is placed at the bottom of the outer case 4 as described above ((1) to 0), and in the next operations (5) to (8) in the same figure, the outer case 4
The stroke length of the piston rod 125a in the stepping air cylinder 125 is determined by a limit switch (not shown, but this switch is attached to the transfer plate) that detects the height from the bottom of the cylinder (() to
Since the length is set to be shorter than in case (4), the next bagged product S is placed gently on top of the bagged product on the bottom row. In this way, the bagged products are stacked in the cardboard case layer by layer, and when a predetermined number of layers (5 in the illustrated example) have been stored, the case is replaced with the one described with reference to FIGS. 5A and 5B. It will be ejected according to the specified operation.

Next, a new cardboard case is placed on the transfer plate 12.
4, the process returns to steps (1) to (4) in FIG. 9B, and this is repeated to sequentially pack the bagged items into the outer case 4.

As described above, if the boxing device shown in Figures 8C to 8E is used, the support plate (
(See reference numeral 45 in Figure 9A) is not necessary, so
Before packing bagged products into boxes, open the bottom flap of the outer case 4 (
Bottom flap) 4e can be closed in advance. The sequence of assembling the cardboard boxes in the row indicated by the symbol Q in FIG. 3A is a schematic illustration of the case where bagged items are stored in boxes whose bottoms are closed in advance.

In addition, in the explanation using FIGS. 8C to 8E and FIG. 9B, a lifter indicated by the reference numeral 57 is illustrated, but instead of this lifter, a wave type table (00 which can be raised and lowered) shown in FIGS. 8A to 8B may be used. You can also do it.

[Modifications of embodiments other than those described above] In the embodiments of the present invention described above, the driving device expressed as a cylinder typically means an air cylinder, but hydraulic pressure, water pressure, or other pressure sources may be used. Also, a motor may be used as the electric drive means.

In addition, a vertical billow type bag making and filling machine and a weighing machine linked thereto are installed in the front stage of the conveyor 11 in the above embodiment, and sealing is performed while measuring and filling snacks, etc., and the sealed bag-like products are packed in one or more rows. Of course, they may be introduced into the apparatus of the present invention in rows.

Furthermore, as already mentioned, in the specification of the present invention,
Although a means for arranging the bagged products conveyed in a single row on the conveyor into multiple rows is also disclosed, it is not necessarily necessary to use this double rowing device. That is, as an example, articles sent in three rows may be immediately introduced into the aggregation device.

[Effects of the Invention] According to the present invention, a packaging method and a packaging method are particularly suitable for application to soft packaging products such as snack foods that have unique properties such as easy breakage, moisture absorption, and flavor scattering properties. This type of bagged product, which can provide equipment, often loses air or gas inside the bag during transportation, storage, or other handling, and if this happens, the product inside is destroyed, reducing the product value. significantly reduced. Therefore, the present invention
These items were first lined up in multiple rows, then aggregated so that they were close to each other, and the aggregated items could be stored inside the case while being supported from above and below. Since a large number of bagged items are stored in close contact with each other, the items do not move around inside the bag during transportation, storage, etc., and are always kept tight to minimize damage. do.

In addition, since items are stored by forcibly pushing them into the outer case, even if the edges of the bagged items protrude to the outside of the outer case to some extent, the pushing pressure forces them to Moreover, since the articles can be pushed into the case in an orderly manner, it is also practically advantageous in that it is possible to provide a packing method tighter than 4 degrees.

Furthermore, according to the boxing method and device of the present invention, a plurality of flexible and easily deformable bagged products are aligned in a partially overlapping state, and then pushed into an exterior corrugated cardboard box, and then placed between the top and bottom of the cardboard case. Boxing can be done by applying the same pressure to the flaps in both directions. Therefore, there is no need for a large-sized exterior case as in the conventional case, and there is also the effect of reducing packaging material costs.

Moreover, according to the method and apparatus of the present invention, it is possible to achieve labor saving by mechanizing the packing work, and also to eliminate the conventional manual packaging, which has the advantage of reducing running costs.
