Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention is applicable to approximately spherical coverings such as spherical vegetables such as cabbage, lettuce, or turnips, or approximately spherical fruits and vegetables such as spherical fruits such as apples and tangerines. This invention relates to a device for wrapping a packaged item in a single synthetic resin packaging sheet.

[Prior Art and Problems to be Solved by the Invention] For example, Japanese Patent Application Laid-Open No. 58 (1983) has proposed an apparatus for wrapping approximately spherical articles such as lettuce with a packaging sheet such as a synthetic resin film that is approximately square in plan view. - In Publication No. 188803, a synthetic resin film placed on a roughly hemispherical vacuum cup and an article placed on the top surface of the synthetic resin film are drawn into the vacuum cup by vacuum, and the synthetic resin film is placed between a pair of film holders. A plate pulls the top surface of the packaged object, and a film squeezing member, which approaches the pair of film abutment plates from directions 90 degrees apart in plan view, draws the corner of the synthetic resin film to the top side of the packaged object. A device has been proposed in which the aperture is configured to be tied up with a binding device such as a metal clip.

According to this prior art, for an object to be packaged that is extremely small compared to the diameter of the vacuum cup, the film abutment plates that are close to each other are immediately above the top surface of the object to be packaged. It is not possible to tightly wrap the synthetic resin film along the outer circumferential surface, and conversely, if the size of the packaged item is larger than the vacuum cup, the packaged item cannot fit into the vacuum cup.
Since it cannot be packaged, it has had the disadvantage of having to prepare vacuum cups of various sizes.

Furthermore, in Japanese Patent Application Laid-open No. 63-33208, a pair of clamping means for clamping a pair of opposing corners of a rectangular packaging sheet are configured to move toward each other horizontally toward the center of the device. A recess in the center of the device is provided with a tray that can be moved up and down, and at the same time as the pair of clamping means move toward each other, the tray holds the center of the packaging sheet and the approximately spherical object to be packaged. A pair of clamping bodies are lowered in the loaded state, and at the lowered position, the pair of clamping bodies are folded upward so as to raise the corner of the packaging sheet that is 90 degrees away from the clamped corner. A pair of slide plates are arranged above the pair of clamping bodies and configured to move toward each other in the same direction as the clamping bodies, so that the pair of free end-shaped The corners are folded on top of the top surface of the packaged object, and the pair of corners released from the clamping means are brought together and twisted by the twisting means facing each other at a radially outer position of the receiving tray and approaching. A device is proposed in which the device is configured to move in and out of the device, and the tray is configured to rotate around a vertical axis.

In this prior art, self-E11 in the packaging sheet
The pair of clamping bodies that raise the end-shaped corners are each formed into a U-shaped cross section so as to surround the outer periphery of the packaged object, and are vertically elongated so that the upper and lower ends of each clamping body are open.

Therefore, the inner surface of each clamping body is planar and does not follow the substantially spherical surface of the packaged object, and the pair of clamping bodies has an inner surface that is in contact with the largest diameter part of the packaged object with the packaging sheet sandwiched between them. For example, since the packaging sheet cannot be brought closer to the pressure any more, slack or wasteful wrinkles tend to occur, for example, in the lower hemisphere of the packaged object, where the surface of the package sheet does not come into close contact with the packaging sheet.

In addition, even if such wasteful wrinkles or loose parts occur in the packaging sheet, they cannot be corrected, and the packaging sheet cannot be beautifully wrapped along the spherical surface of the object to be packaged. There is.

In order to eliminate this inconvenience, if the inner surfaces of the pair of clamping bodies are formed into a spherical surface that matches the spherical surface of the object to be packaged,
This creates an inconvenience in that each time the size of the packaged object differs, the holding body must be replaced with one of a shape that matches the size of the packaged object.

Furthermore, if a plurality of pairs of the above-mentioned clamping bodies are used and these plural pairs of clamping bodies are attached to the packaged object at the same time, there will be no margin at the restraint point of the packaging sheet sandwiched between the surface of the packaged object and the clamping bodies. Therefore, there was also a problem that the packaging sheet was torn.

The present invention aims to eliminate the disadvantages and disadvantages of these conventional techniques.

[Means to solve the problem]

In order to achieve this object, the first claim of the present application provides a cradle for placing a rectangular synthetic resin packaging sheet and a generally spherical packaged object disposed approximately at the center of the upper surface of the packaging sheet. , a plurality of holding members disposed radially outward from the cradle and configured to squeeze the packaging sheet toward the outer surface of the packaged object, and further comprising a plurality of holding members disposed radially outward from the cradle and configured to squeeze the packaging sheet toward the outer surface of the packaged object, and further comprising In a packaging device for a substantially spherical object, the device is equipped with a packaging mechanism in which at least one of the two pairs of corners is twisted or clipped onto the top surface of the object. , each of the holding members is formed in a multi-jointed shape so as to substantially follow a vertical side surface of the outer surface of the object to be packaged; The structure is such that the members approach the packaged item with a time lag.

[Action/effect of the invention]

According to this configuration, a plurality of holding members disposed on the outside of the holder on which the packaging sheets are placed, which wrap the substantially spherical object to be packaged from below, approach the packing sheet to wrap the object to be packaged from below. The packaging sheet can be drawn along the outer surface, and at least one of the two pairs of opposing corners of the packaging sheet drawn toward the upper surface of the packaged object can be drawn. The packaging can be completed by twisting or clipping on the top of the item.

In this case, according to the first aspect of the invention, each of the holding members is formed in a multi-jointed shape so as to substantially follow the vertical side surface of the outer surface of the object to be packaged. A packaging sheet that can be curved so as to come into contact with the spherical outer surface of the packaged object in order from the bottom side of the packaged object, and is arranged between the inner surface of these holding members and the packaged object. It is drawn and formed along the surface of the packaged object without loosening.

At the point where the wrapping sheet to be drawn and formed is pressed against the surface of the packaged object by the holding member, the wrapping sheet is no longer movable, so if multiple holding members approach at the same time, In this case, there is a risk that the packaging sheet may be torn if there is not enough space between adjacent restraint locations.

On the other hand, in the invention of claim 2, the plurality of holding members approach the outside of the packaged object not at the same time, but sequentially with a time difference. The wrapping sheet is squeezed in such a way that the portion of the packaging sheet in a free state other than the portion of the packaging sheet that is pressed against the surface of the object and restrained is pressed against the surface of the object to be packaged and restrained by a holding member that approaches later. The constraints associated with molding can be shifted in time and location, and accidents such as tearing the packaging sheet during the packaging process do not occur.

As described above, according to the invention of the first claim, the packaging sheet can be wrapped around a substantially spherical object without slack, and according to the invention of the second claim, the packaging sheet can be wrapped around the object to be wrapped along the surface. When drawing and forming a packaging sheet, there is no accident of tearing the packaging sheet, and both inventions have the excellent effect of allowing beautiful packaging to be carried out.

When drawing along the outer circumferential surface of the packaged object, it has a multi-jointed structure that can be bent freely along the approximately spherical outer circumferential surface of the packaged object C, and an appropriate number of connections can be made. A spring 44 connected between the back surfaces of the pieces 42 and 42 biases the adjacent connecting pieces 42 in a direction in which they extend linearly, and also forces the adjacent side surfaces of the radially arranged holding members 6 into an annular shape. The springs 45 are connected to each other so that adjacent holding members 6 are not arranged unevenly.

Note that reference numerals 46 and 47 are cushioning materials such as sponges that prevent the surface of the soft object C from being damaged when the connection piece 42 of the holding member 6 comes into contact with the surface of the object C.

In the embodiment, the holding members 6 consist of eight pieces (four pairs) (
In order to clarify the arrangement relationship, subscripts A to D are added below). As shown in FIGS. 11 and 12, the four horizontal drive bodies 51 drive the upper ends of the four holding members 6A arranged at 90 degrees toward the upper surface of the object to be packaged. The rack portion 50 formed on the side surface of each horizontal drive body 51 is engaged with the pinion 55 provided in the guide rail 48. As shown in FIG. 10, a chain sprocket 57 attached to each drive shaft 56 of a binion 55 is wound around with a chain 58, and four horizontal drive bodies 51 are moved in and out at the same time by one drive motor M1. It is.

Among the eight holding members 6, holding members 6B and 6C
and a pair of holding members 6D arranged 90 degrees apart from the pair of holding members 6B and 6C.

6D indicates the four corners At, A2°A3.
These holding members start operating later in time than the holding member 6A that holds the four sides of the packaging sheet A. The holding members 6D, 6D are configured to start operating later than the holding members 6B, 6C.

Since the holding members 6B and 6C correspond to the location where the corner folding means 7 described later is located, the upper ends of both holding members 6B and 6C are moved toward the upper surface of the object to be packaged C. The horizontal drive bodies 52, 53 are driven by separate drive motors M2. Activate with M3.

In addition, a pair of holding members 6D, 6D corresponding to the location of the corner gathering means 8, which will be described later, are simultaneously operated into the cell. 65
(separate drive motors may also be used if necessary).

Next, the structure of the horizontal operating bodies 52 to 54 will be explained.
As shown in FIGS. 13 to 17, a rank portion 68 and a rank portion 68 formed on one side of the horizontal actuating bodies 52 to 54, which are fitted into a pair of upper and lower guide rails 66, 67 so as to be movable back and forth, and

The folding means 7 is provided so as to be interlocked with the movement of the horizontal operating bodies 52 and 53, which are provided to move forward and backward relative to each other at the opposing positions.

That is, the idler pinion 71 is supported by the shaft 72 in the space 70 that communicates with the upper and lower middle portions of the horizontal operating bodies 52 and 53 in the longitudinal direction. A movable rack body 74.7 in which the upper tooth surface of the idler pinion 71 is slidably inserted into both the upper guide rail 66 and the horizontal operating body 52 or 53 while meshing with the fixed rack 73 in the
4, thereby creating a so-called double-speed movement mechanism in which the moving rank body 74 can move forward or backward at double the speed of the forward motion of the horizontal operating body.

At the opposite ends of the circularly movable rack bodies 74.74 corresponding to the horizontal operating bodies 52 and 53, flat pressing plates 75.76 are projected at different vertical height positions. The horizontal operating body 52 corresponding to the holding plate 75 at the position is projected first, and the horizontal operating body 53 corresponding to the holding plate 76 at the upper position is projected from behind.

Similarly, the gathering means 8 should be provided at a location where the folding means 7 and the folding means 7 intersect with each other at 90 degrees in plan view,
It is provided so as to be interlocked with the movement of a pair of horizontal operating bodies 54 and 54 which are provided to move forward and backward relative to each other at opposing positions, and the attachment of the movable rack body 74 to the rain horizontal operating bodies 54 is as described above. The location is the same as that of the folding means 7, and flat, fork-shaped gathering plates 77, 78 are made to protrude at different vertical height positions from the opposite ends of the removable rack body 74.

A support rod 60 connected to the upper end of the holding members 6A to 6D is connected to the front ends of the horizontal drive bodies 51 to 54 so as to be movable forward and backward, and is biased to protrude by a spring 61.
54 acts as a cushion when the object C is held in place.

Note that corner portions Al, A2. The four pressing rollers 80 that press and hold A3A4 against the support plate 3 are attached to the upper surface of the support plate 3 via spring rods 81 or the like so that their base ends can swing up and down, and can be adjusted to suit the operator's switch operation. It is preferable to use a driving means such as an electromagnetic solenoid that moves up and down.

With this configuration, the synthetic resin film fed out by the packaging sheet supply device (not shown) provided on one side of the main body frame 2 of the packaging device 1 is cut into a substantially square shape in plan view using a cutter means, and the packaging sheet A is formed. , the substantially central portion of the packaging sheet A is placed at a location covering the hole 4 in the support plate 3 (see the dotted chain line in FIG. 2).

In this case, the moving means 11 provided with the presser body 9 and the twisting means IO is moved laterally from the four holes so as not to interfere with the arrangement work of the packaging sheet A.

Next, an object to be packaged C such as lettuce is placed on the approximately central portion of the packaging sheet A, and the moving means 11 is moved so that the presser body 9 is positioned above the hole 4,
The lifting drive motor 17 is turned on to lower the presser body 9 as shown in FIG. 18, thereby pushing the packaged object C and packaging sheet A downward through the hole 4.

In this state, as shown in FIG.
! : The object to be packaged C is supported by the pedestal 5 which is biased downwardly by an upward spring 38, and the upper surface of the object to be packaged C is pressed by a presser body 9 and positioned below the support plate 3. At this time, the lower ends of the eight holding members 6A to 6D are located below the pedestal 5, and the eight holding members 6A to 6D are located below the pedestal 5.
Since A to 6D are arranged in a substantially conical shape so as to extend radially outward and diagonally upward, each side of the packaging sheet and the packaged object C protrude outward from the eight holding members 6A to 6D. Never.

Next, as shown in FIGS. 10 and 19, the four holding members 6A are placed on the outer peripheral surface of the packaged object C through the packaging sheet A so as to squeeze up the four sides of the packaging sheet A other than the corners. approach towards. For that purpose, drive motor M1
By turning ON, the four horizontal actuating bodies 51 are simultaneously operated to protrude toward the upper surface of the packaged object C via the chain 58 and the chain sprocket 57.

The lower ends of the four holding members 6A are located below the pedestal 5, and each of the four holding members 6A has a connecting piece 42 connected with a pin 43 to form a multi-jointed shape that can be bent in a series. As the upper end of the holding member 6A approaches the upper surface of the object to be packaged C, it contacts the spherical surface of the object to be packaged C in order starting from the connecting piece 42 at the lower position. The wrapping sheet can be formed so as to be squeezed upward from the surface side of the lower half of the packaged item, and the packaging sheet does not become loose on the lower half of the packaged item.

Next, the presser body 9 is raised, and the moving means 1 is moved so that the lateral twisting means 10 of the presser body 9 is located above the hole 4.
1 is driven.

Substantially parallel to the above-mentioned work, the four holding members 6A
The wrapping members 6B and 6C facing each other on sides inclined at 45 degrees in plan view are moved toward the object C to be packaged, and the packaging sheet 1-A is drawn in the same manner as described above.

At this time, the packaging sheet A
A flat holding plate 75, 76 which is a folding means 7 for folding the corner parts At and A2 on the upper surface side of the packaged object C.
are provided at different height positions, so in order to first fold the corner A1 on the upper surface of the packaged object C using the pressing plate 75 at the lower position, first move the corresponding horizontal operating body 52 forward. Then press the other corner A2 with the holding plate 76 at a high position.
The other horizontal actuating body 53 starts moving forward in order to fold it above the corner Al (see FIG. 20).

And drive motor M2. The horizontal actuating body 52 is located at a position facing each other via the pinion 69 and the rank portion 68 at M3.
53 by a predetermined distance (Hl), the upper tooth surface of the idler union 71 rotating via the fixed rack 73 moves the rack body 74 at a speed twice the forward speed of the horizontal operating body 52 etc. The flat holding plates 75 and 76 attached to the tips of these moving rack bodies 74 and 74 are moved forward by a forward distance (H2) that is twice the forward distance (Hl) of each horizontal operating body. and can be positioned in a vertically intersecting manner on the upper surface side of the object C to be packaged.

Next, a pair of holding members 6D facing each other at 90 degrees from the folding means 7 in plan view.

6D approaches the outer surface of the object C, the pair of horizontal operating bodies 54 and 54 are driven by the drive motor M4, and the multi-jointed holding member 6D moves the packaging sheet 1- A is drawn and formed along the spherical surface of the packaged object C.

The gathering means 8, which is linked to the forward movement of the pair of horizontal operating bodies 54 and 54, consists of a pair of movable rack bodies 7474 facing each other and a fork-like gathering mechanism attached to their tips, similar to the folding means 7. The plates 77 and 78 rotate the chain sprockets 63 on the opposing guide rails 66 via the idler chain sprockets 64 and 64 and the chain 65 using the power of the drive motor M4, and move the horizontal drive bodies 54 and 54 forward in unison. When moved, the movable rack body 74.7 moves forward at twice the speed of its forward movement distance.
The leading edge joining plates 77 and 78 of No. 4 are located at the corner A3 of packaging sheet A. It can be made to stand up with A4 paper in between (see Figures 21 and 22).

In this way, on the upper surface side of the packaged object C, one of the opposing corners At and A2 of the packaging sheet A are the presser plates 75 and 76.
, and the other pair of corners A3. The A4 sheets are brought together in a substantially vertical manner by fork-like joining plates 77 and 78.

After positioning the twisting means 10 of the moving means 11 moved during this work above the hole 4 of the support plate 3, the lifting drive motor 33 of the twisting means 10 is turned on, and the lifting shaft 32 is lowered. and a pair of scissor members 21.21

After that, the rotation drive motor 25 is turned on, and the pair of scissor members 21 and 21 are moved together with the bracket 19 onto the lifting shaft 32.
When the packaging sheet A is rotated several times to the right or left around the axis (see Fig. 23), the pair of corners A3 and A4 are twisted together (see Fig. 24), and the packaging sheet A becomes difficult to unravel. ) When A is a synthetic resin film having extensibility or adhesion, it becomes difficult to restore the twisted corner A5 to its original state.

Next, the lifting shaft 32 is raised to open the pair of scissors 21 and 21 in the twisting means 10, and the moving means 11 is opened.
When the other four holding members 6A are moved to the side from the four holes and the other four holding members 6A are retreated to their original positions, the packaged product placed on the pedestal 5 which is biased upward by the spring 38 is removed. Since the packaged object C is automatically raised to the top of the support plate 3, it is only necessary to take it out.

In addition, as shown in FIG. 25, when the twisted part A5 is manually inserted under the twisted part A5, the twisted part A5 can be held so that it does not unravel due to unnecessary breath. I can do it.

In this embodiment, the folding means 7 and the shifting means 8 and the plurality of pairs of holding members 6B to 6D are configured to move forward and backward in conjunction with each other. The folding means 7 and the shifting means 8 are arranged at positions that do not overlap with each other in a plan view with respect to the holding members 6B to 6D,
It goes without saying that the folding means 7 and the shifting means 8 may be configured to be moved forward and backward by separate driving means, and in this case as well, the plural pairs of holding members are used to hold the packaged items at different times. It can be configured so that it approaches .

Further, the plurality of pairs of holding members can be variously changed to about 5 pairs, 4 pairs, 3 pairs, or 2 pairs depending on the size of the object to be packaged.
