Description

[Detailed Description of the Invention] A. Purpose of the Invention [Field of Industrial Application] This invention mainly relates to a method and apparatus for packaging 20, 30, and 50 garbage bags at once.
In addition to garbage bags, it is also suitable for wrapping sheet-like items such as book covers, diaper covers, and furoshiki made of synthetic resin film.

[Prior art]

Conventionally, this type of sheet material was extremely thin and
Films of about 20 to 10 microns are used, and usually a stack of 20 or 30 films is inputted or mechanically inserted into a completed packaging bag.

[Problem to be solved by the invention]

However, as mentioned above, this type of sheet material is extremely thin and soft, so when it is inserted into an outer bag, the periphery is bent, which not only looks bad from the outside, but also causes damage to the package around the bent part. When a large number of packaging bags are stacked and stored, this difference in thickness accumulates and becomes unstable.

In addition, in order to prevent bends from occurring, it is necessary to carefully correct the bends by hand, which is time-consuming.

On the other hand, in order to insert the bag by simply clamping it from above and below using a mechanical method, the thickness of the clamping plate to be inserted requires sufficient space in the outer bag. If the insertion position of the board into the outer bag is not accurately controlled, there is a risk of breaking the bottom of the outer bag, and the control device requires advanced technology, so the bag is usually packed in a large outer bag with a considerable amount of room.

However, in the latter case, the outer bag is too large, so the laminated sheet material inside is easily disturbed after packaging, and the fabric of the outer bag is not utilized effectively.

The present invention improves the shortcomings of such known methods and devices, and allows even extremely thin stacked sheets to be packaged accurately and neatly without being bent. The main object of the present invention is to provide a method and a device for effectively utilizing a flat tube serving as an outer packaging bag without disturbing the group of objects.

B. Structure of the Invention [Means for Solving the Problems of the Invention] In order to achieve the above-mentioned problem, a group of stacked sheet-like objects is held between upper and lower sides by holding plates, and in that state, a V-shaped or chevron-shaped group is formed. One kind of method is to bend the central part along the ridgeline and supply the tip of a continuous heat-weldable flat tube for the outer packaging bag to the vicinity of the bent sheet group from the ridgeline direction. is expanded into a cylindrical shape to the point where the group of sheet-like objects in the folded state can be inserted while maintaining that state, and then the group of sheet-like objects in the folded state are inserted into the tube together with the holding plate, and the sheet-like object group in the folded state is inserted into the tube, Inside, the group of sheet-like objects stacked together with the clamping plate is returned to a horizontal state, and then the group of sheet-like objects is clamped and fixed from above and below from the outside of the flat tube, and only the clamping plate is removed from the inside of the flat tube. , At the front and back of the stacked sheet group, only the flat tubes are sandwiched from above and below and heated to weld only the upper and lower films of the flat tubes, and the parts of the flat tubes that are connected to the original side are cut. This is a laminated sheet packaging method.

In addition, in order to achieve the above-mentioned object, the present invention is equipped with a flat tube opening opening means for expanding the tip of the flat tube for the outer packaging bag into a cylindrical shape, and a clamping plate for clamping the stacked sheet group from above and below. While holding the sheet group between the clamping plates, bend the flat tube into a V shape or a chevron shape by making creases in the length direction of the flat tube,
a sheet-like object group folding/inserting means that is inserted into the tip of the flat tube, and then returns the sheet-like object group together with the holding plate horizontally within the flat tube, and pulls out the sheet-like object group while leaving the sheet-like object group inside the flat tube; , after the sheet-like object group folding and inserting means reaches a horizontal state within the flat tube, and until the sheet-like object group is pulled out from the flat tube, an insertion sheet-like object is inserted that holds the sheet-like object group from above and below from the outside of the flat tube. object group holding means; mouth and bottom sealing means for welding and sealing the flat tubes at the front and rear positions of the sheet-like object group after the sheet-like object group bending and inserting means is extracted from the flat tube; and the bottom section. A flexible laminated sheet packaging device comprising: cutting means for cutting the flat tube near the sealing means;

When the clamping pressure of the clamping plate located inside the flat tube is released and the clamping plate is pulled out from the flat tube body, the sheet-like objects remain in a flat state within the flat tube band.

In this state, the upper and lower films of the flat tube band of the group of sheet-like objects inserted from the outside of the flat tube into the inside are welded together, and the parts that continue to the original fabric side are cut together to form the sheet. A package is formed in which the group of objects is flatly packaged.

Next, in the apparatus described in claim 2 for carrying out the above-mentioned method, first, stacked sheets are fed in a flat state to the clamping portion of the sheet group folding and inserting means. In this sheet-like object folding and inserting means, the above-mentioned sheet-like object group is clamped from above and below, and folded into one of a V-shape and a chevron-shape while being held.

In this way, the sheet-like object group with the fold ridge line is expanded into a cylindrical shape in the direction of the fold ridge line by the sheet-like object folding and inserting means and by the flat tube mouth expanding means. Insert the flat tube completely into this tube through the opening at one end.

Next, the holding portion of the sheet-like object bending and inserting means that holds the sheet-like object group in a V-shape or chevron shape is flattened, and along with this, the held sheet-like object group and the outer flat tube are also flattened. Become.

Next, the insertion sheet group pressing means is activated,
The group of sheet-like objects inside the flat tube is clamped from the outside of the flat tube to fix the flat tube and the group of sheet-like objects.

In this way, the clamping pressure of the clamping portion of the sheet-like object folding/inserting means is warmed up, and when this insertion means is pulled out, the sheet-like object group described above remains in the flat tube.

Next, the mouth and bottom sealing means are operated to weld and seal the flat tubes at the front and rear of the sheet group, and the flat tubes connected to the sealed package are cut on the original side by a cutting means to separate them. A packaged body is obtained.

[Description of method invention and device operation]

Next, the method of the present invention will be explained together with the operation of the apparatus of the second invention configured as described above.

First, the stopper 21 of the bag making machine A is placed on the product holder 2.
0, the gripping claws 25 of the first conveyance means B are opened, and the bag group _J0 on the product holder 20 is placed on standby in a state where it can be gripped. Further, the insertion means C is located at the position of the pneumatic cylinder device 3 located closest to the product holder.

1, 44, 49, 52 and 57 so that the maximum distance between the mouth sealing means D and the bottom sealing means G is slightly longer than the length of the bag J. As such, the strokes of the pneumatic cylinders 56 and the pneumatic cylinders 32 of the insertion means C can be adjusted by known means, for example by adjusting the position of a stroke control stopper or by detecting the position of the movable part with a sensor for each pneumatic cylinder device 32,56. This may be done by controlling the incoming air by actuation of a control valve.

Then, the tip edge K ₀ of the flat tube K is pulled out to the cutter 51 position.

The flat tube K is usually a flat tube made of synthetic resin molded by an inflation method, and the width of the flat tube K is such that the sum of the width and thickness of the bag group J ₀ is slightly wider than this. Use the one.

These means are operated by the sequence control device M in the following order.

First, the bags J are neatly stacked on the product holder 20 of the bag-making machine A, following the stopper 21 that is sent out in sequence. When a predetermined number of bags J is reached, the stopper 21 is raised, and at the same time, the clamping claws 25 are closed, and the bags J are Group J ₀

b, the second conveying means I is moved by the spring 58
compressing and further approaching the mouth sealing means D;
The tip edge _K0 of the flat tube K is connected to the mouth sealing means D.
Push it out to the position (see Figure 8).

Next, the suction cups 43a, 43 of the mouth expanding means E
b approach each other and suction the tip of the flat tube K from above and below under reduced pressure, and the suction cups 43a, 4
3b and the clamping jaws 53a, 53b of the second conveying means I
are vertically separated by the pneumatic cylinder devices 44 and 57, and as a result, the upper and lower films at the tip of the flat tube K are separated from each other, and the tip of the flat tube K is greatly expanded vertically, as shown in FIGS. It becomes cylindrical as shown in Figure 9.

The cylindrical cross-sectional shape of this flat tube K is determined by the positions of suction cups 43a and 43b shown in FIG. Therefore, when the bag group _J0 is bent into a V-shape by the inserting means C as described above, the upper suction member 43a is spread horizontally and the cross-sectional shape of the rectangular tube is changed to an inverted trapezoid or an inverted triangular shape. Make it. When the bag group J ₀ is bent into a ∧ shape, suction cups 43a, 43 are used.
Reverse the arrangement of b.

Then, the insertion means C is moved in the direction of the mouth sealing means D by the pneumatic cylinder device 32, and the second conveying means I, the holding means F, the bottom sealing means G, and the cutting means H are moved together. return to position.

As the insertion means C moves, the bag group _J0 , which is held and bent by the upper and lower holding plates 33a, 33b and 36a, 36b, is inserted into the flat tube as it is, and the bag group _J0 is inserted into the flat tube as it is. When the rear end of the insertion means C has just passed the mouth sealing means D, the insertion means C stops.

Next, the upper and lower holding plates 33a, 33b, 36a, 3
6b is returned to the state shown by the solid line in FIG. 3 again by the pneumatic cylinder devices 34a, 34b, 37a, and 37b. Along with this, the flat tube K separates from the upper suction cup 43a, and both become flat. At this time, it is better to release the reduced pressure state of the suction cups 43a and 43b.

Further, after returning to the state shown by the solid line in FIG. 3, the clamping pressure by the clamping plates 33a, 33b and 36a, 36b is slightly weakened as necessary.

During the operation of these insertion means C in the flat tube K, the first conveyance means B returns to the standby state.

Next, the pressing means F are brought close to each other, and the protrusion 4 thereof is
8a and 48b sandwich the flat tube K and the bag group _J0 therein from above and below.

Next, the insertion means C is returned to its original position and returned to the standby state again. It is better to do this movement slowly.

Then, the mouth sealing means D, the bottom sealing means G and the cutting means H are operated all at once to weld and cut the flat tube K in the front and back of the bag group _J0 in the transverse direction, and these means returns to the upper and lower positions, and all operating members move in order.

Thus, between the mouth sealing means D and the bottom sealing means G, a package L is obtained in which the bag group J ₀ is completely wrapped (see FIG. 13).

This package L is conveyed downward or sideways.

Below, this operation is performed by placing a predetermined number of bags J on the product holder 20.
Repeat for each stack.

In the above-described embodiment, the sequence control described above is performed by the sequence control device M for each electromagnetic control valve of each pneumatic cylinder device and other power parts in an electromagnetic or electronic sequence. Of course, the present invention is the same even if it is air control or control using a purely mechanical sequencer or computer.

Although pneumatic cylinder devices have been exemplified as power sources for the reciprocating motion of the first conveying means B and the second conveying means I, the present invention does not affect the present invention even if the reciprocating motion is performed using other known reversible rotary motors. It doesn't change.

C. Effects of the Invention Among the inventions constructed and operated as described above, in the method invention, even a group of extremely thin stacked sheets can be accurately and neatly packaged without being bent, and a packaging bag can be used. In this case, the flat tube serving as the outer packaging bag can be effectively used without the sheet-like objects being disturbed.

In addition, in the device invention, since it is constructed and operates as described above, the method invention described above can be carried out, and the bag group is held from above and below and folded into a V-shape or chevron-shape, and then expanded into a cylindrical shape. It is inserted into a flat tube, and since it is stretched horizontally, it remains cylindrical at the time of insertion, and the bottom has not yet been formed, making it easy to insert. The bag group is not wrinkled or turned over, and is accurately accommodated in the flat tube, and when the insertion means is removed from the flat tube, it is easy to pull out because it is pulled out without being at the bottom of the flat tube.
