Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a multi-tiered empty can package for empty cans filled with foods, beverages, pet foods, non-foods, etc.

(Prior Art) In general, many of the empty cans manufactured by can manufacturing companies (can factories) are used for packaging, transportation, etc.
From the viewpoint of workability in canning work, etc., referring to FIG. 7, a pallet 100 that can be transported by a forklift is
A predetermined number of empty cans 101 are arranged in multiple rows and rows on the top, and the same number of empty cans 101 are further arranged with the partition plate 102 in between, and this is repeated to form groups of empty cans in several stages (usually 15 to 19 stages). E are stacked, a holding plate 103 is placed on top of the group of empty cans on the top tier, a cable tie 104 is passed between the holding plate 103 and the pallet 100 to bind them together, and finally a shrink film 10 is placed from above.
5, the entire empty can is wrapped, and the shrink film 105 is heat-shrinked to prevent the empty can 101 from being damaged and to prevent dirt, dust, insects, etc. from entering the empty can 101. and then sent to canning companies (canning factories).

The process of forming this multi-tiered empty can package is, for example, as follows.

First, the group E of empty cans sent on the net conveyor is sorted into a predetermined arrangement (for example, in Fig. The containers are arranged in multiple rows so that the maximum number of cans can be arranged in a predetermined area by shifting each row by a radius.

Next, support rods (one in each empty can) are inserted from above into the empty cans at the rear end of each row of the aligned empty can group E, and these support rods are advanced (at this time, (The front end of the can alignment section also moves forward.) Then, a group of empty cans E in a predetermined arrangement is placed on the pallet 100 placed on the hoist in front of the can alignment section.

Next, the hoist is lowered to approximately the height of one empty can, and then a partition plate 102 made of a plate whose length and width are slightly larger than the length and width of the empty can group E is placed on the empty can group E ( At this time, the front butterfly of the can alignment section returns to the can alignment section, and the support rod retreats to its original position and returns above the empty cans).

In addition, between the step of advancing the aligned empty can group E and the time when the front end of the can alignment section returns, each empty can at the front end of the subsequent empty can group E is provided with a support other than the support rod. A rod is inserted downward and prevents the empty can group E from moving forward.

The above steps of arranging empty can groups, inserting support rods, advancing the aligned empty can groups onto a pallet and stacking them, lowering the hoist, and placing partition plates are repeated to form empty cans in a predetermined arrangement. After stacking the group E a predetermined number of stages, place the empty cans group E on the top row.
After placing a cover plate 106 made of paperboard and a press plate 103 made of plastic or the like that is slightly larger than the vertical and horizontal lengths of the empty can group E (the press plate 103 is placed on the cover plate 106), the hoist is further lowered. , a pallet 100 stacked with empty cans E is placed on a pair of chain conveyors, the pair of chain conveyors are driven to carry out the pallet 100 from the palletizer section, and then the pallet 100 is transferred to another pair of chain conveyors, etc. It is transferred to the band machine section by the conveying means of
00 to prevent the multi-tiered empty cans from falling, and then transport them to the auto-wrapping section using a conveying means, where a heat-shrinkable bag (shrink film) is placed over the multi-tiered empty cans. 10
5) (in some cases, bags are made by covering with a film and then welding), and then placed in an oven to heat-shrink the bag to complete a multi-tiered empty can package.

Next, dismantling of multi-tiered empty can packages in a cannery is carried out, for example, as follows.

First, the multi-tiered empty can packages are placed on the deparatory conveyor using a forklift, and the shrink film 105 is manually broken and removed (before being placed on the deparatory conveyor, the shrink film 105 is
05 may be removed. ).

Next, the deparatory conveyor is driven to transport the multi-tiered empty cans to the press plate removal section. The presser plate removal section includes a lifter on which multi-tiered empty cans are placed and a presser plate remover installed above the lifter.

In the holding plate removal section, the cable tie 104 is manually removed.
After cutting and removing the empty cans, the multi-tiered empty cans are slightly lifted with a lifter, and the presser plate removing device automatically removes the presser plate 103 from above the empty can group E, and stacks it at the presser plate collection area.

Next, the multi-tiered empty cans are placed on the standby conveyor. This standby conveyor allows subsequent multi-tiered empty cans to wait until the unloading operation of the preceding stacked empty cans at the next empty can discharge section is completed.

Next, the multi-tiered empty cans are conveyed to the empty can discharge section by a standby conveyor. The empty can discharging section includes a lifter on which multi-tiered empty cans are placed, a partition plate holding device installed above, an empty can discharging device, and a partition plate removing device.

In the empty can discharging section, first, the multi-tiered empty cans are raised by a lifter until the lower end of the topmost can matches the height of the net conveyor in front of the empty can discharging section. (By interlocking with the device, the ascent can be stopped automatically.) Next, after the partition plate 102 on which the empty cans on the top tier are held is held by the partition plate holding device (usually 2 ), the cover plates 106 placed on the empty cans are removed by a partition plate removal device (e.g., a device with a vacuum suction) and stacked in the partition plate collection area, and further in the horizontal direction of the empty can group E. An empty can discharging device having a pushing plate longer than the length pushes the empty cans at the rear end of the empty can group E forward, and discharges the uppermost empty can group E onto the front net conveyor.

After that, the lifter is raised again, and the lower end of the empty can group E, which is the next highest stage, is aligned with the height of the net conveyor in front of the empty can discharge section, and then the partition plate on which this empty can is placed is placed. After the partition plate 102 is held by the partition plate holding device, the partition plate 102 placed on the top empty can group E (the top empty can group E of the package before disassembly and the next empty can group) The partition plate between E and E is removed by the partition plate removing device, and the empty cans in the top row are placed on the front net conveyor by the empty can discharging device.
discharge.

After repeating the above-mentioned empty can discharging operation at the empty can discharging section to complete discharging all empty cans, the lifter is lowered and the empty pallet 100 is transferred to the pallet discharging conveyor. Remove from the discharge section.

(Problems to be Solved by the Invention) However, during the above-mentioned multi-tiered packaging formation work and multi-tiered packaging disassembly work, stacked empty cans often fall.

This tends to occur during transport from the palletizer section to the band machine section during package formation work, and during package disassembly work from the stage after the shrink film 105 is removed to the empty can discharge section. This tends to occur during transportation.

In particular, in the latter case, multi-tiered empty can packages are transported by forklift, truck, etc. from a can manufacturing factory to a canning factory, and are subjected to considerable vibration during transportation.
Furthermore, since it may be subjected to rough handling, the stacking may be too high, the binding of the cable ties 104 may be weak, the thickness of the shrink film 105 may be thin, or the degree of shrinkage of the shrink film 105 may be small. If these factors are combined, the packaging may be tilted, or the empty cans in the front row (the empty cans forming the outermost row on all four sides) of each of the four stacked tiers may Since the canner will arrive at the cannery in a disordered arrangement, when the shrink film 105 is peeled off and transported (when it starts moving and when it stops), it is necessary to The cans tend to fall, and then the empty cans in the front row on all four sides tend to fall.

Normally, only the empty cans on the top and next tiers fall, but if the degree of inclination of the package is large and the direction of this inclination coincides with the moving direction of the conveyor, empty cans in the lower tiers will also fall. It may fall.

If a dropped empty can hits the floor with its opening side facing down, the flange of the empty can will be considerably deformed and become unusable, so we do our best to prevent empty cans from falling. Must.

(Means for Solving the Problems) The present invention has been made to solve the above-mentioned problems, and is intended to prevent empty cans from falling during the formation and disassembly of multi-tiered empty can packages. To achieve this objective, the present invention arranges a pallet placed at the bottom of a multi-tier stack of empty cans and empty cans for canning, and aligns the empty cans stacked on the pallet. a group, and a partition plate having a length slightly larger than the vertical and horizontal lengths of the group of empty cans and disposed adjacent to the top and bottom of the group of empty cans to be stacked;
a holding plate having length and width approximately equal to the partition plate and placed from above the group of empty cans in the uppermost tier; and a binding band that is stretched between the holding plate and the pallet to bind the multi-tiered empty cans. , a shrink film that is placed over the bound state of the binding band and tightly covers the entire multi-tiered empty cans by heat shrinkage;
In the multi-tiered empty can package, the partition plate on which at least the uppermost group of empty cans is placed is placed on at least two opposing edge portions of the partition plate, and A bent partition plate is formed with an upwardly bent portion so that the empty cans arranged in the front row can be placed in an inwardly inclined state by partially placing the empty cans thereon.

(Function) Therefore, in the multi-tiered empty can package of the present invention, the partition plate on which at least the uppermost group of empty cans is placed is placed between at least two of the edge portions facing each other.
By using a folding partition plate with the edge part of the side bent upward, the empty cans in the front row located on the folded edge part tilt inward and come together, preventing the empty cans from tilting outward. It is possible to prevent the objects from falling.

(Example) Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
First, the configuration of the first embodiment shown in FIGS. 1 to 5 will be explained.

Reference numeral 1 denotes a pallet, which is placed at the bottom of a multi-tier stack of empty cans to be described later. This pallet 1 is made of wood or plastic and has a fork insertion hole 2 that can be transported by a forklift.

E is a group of empty cans, in which empty cans 3 for canned goods are arranged adjacent to each other and stacked on the pallet 1, and as in the past, this group of empty cans E has a radius of cans in each row. The cans are arranged so that the largest number of cans can be arranged in a predetermined area by shifting the cans.

In the empty can 3, the can lid 3a is wrapped around one end of the can body 3b, and the other end of the can body 3b is left open, so that the can lid can be rolled up after filling with contents. It has a flange portion 3c that projects outward. Then, with the can lid 3a side down, flange part 3c
are arranged with the top facing up.

Reference numeral 4 denotes a partition plate, which has a length slightly larger than the vertical and horizontal lengths of the empty can group E, and is disposed adjacent to the upper and lower parts of the empty can group E to be stacked. It is made of flat paperboard approximately 1 mm in size and approximately rectangular in shape.

In addition, this flat paperboard partition plate 4 is
It is arranged vertically adjacent to the second empty can group E2 from the top.

5 is a folding partition plate, and the top empty can group E1
and the second empty can group E2, that is, the position where the uppermost empty can group E1 is placed.
This folding partition plate 5 has two opposing sides of the edge portion.
The bent portions 5a, 5a are formed by bending the edge portions of the sides (two sides in the traveling direction when forming or dismantling the package) upward.

The material of this folding partition plate 5 is the same as that of the partition plate 4.
Paperboard is used in the same way.

The bending angle θ1 by hand or machine is
The angle was approximately 15 degrees to approximately 40 degrees in the no-load state where empty can group E is not placed (Fig. 3), but in the loaded state, the angle is almost constant due to band binding, etc., which has little relation to the angle in the no-load state. The bending angle θ2 (approximately 6
degree) (Fig. 4). Of course, if the material and thickness of the partition plate are different, the bending angle θ in the no-load state may vary.
Even if 1 is the same, the bending angle θ2 in the loaded state will be different. The key is to make the bending angle θ2 greater than 0 in the loaded state.

Further, although the length l of the bent portion is approximately 12 mm in the embodiment, it may be within a range of approximately 5 mm to approximately 20 mm.

In addition, the reason why this folding partition plate 5 is used only at the position where the top empty can group E1 is placed in the embodiment is because the top empty can group E1 is most likely to fall. Not limited to this embodiment, depending on various situations, such as increasing the number of stacked tiers or reliably preventing empty cans from falling, multiple tiers such as the top tier, second tier, third tier, etc. The bent partition plates 5 may be used, or all the partition plates may be bent partition plates 5.

Reference numeral 6 denotes a holding plate, which is placed on top of the top empty can group E1 via a cover plate 7. This holding plate 6 has approximately the same length and width as the partition plate 4, and is made of plastic. etc. is formed.

The cover plate 7 may also be used as the partition plate 4, or may be provided integrally with the lower surface of the presser plate 6.

Reference numeral 8 denotes a binding band, which is used to bind the multi-tiered empty cans by wrapping it around the pallet 1 using the presser plate 6. The binding band 8 is a high-strength plastic band.

Reference numeral 9 denotes a shrink film which is placed over the bundled state of the binding band 8 and tightly covers the entire multi-tiered empty cans by heating and shrinking.

Next, the operation of the first embodiment will be explained.

As mentioned earlier, empty cans sometimes fall during transport from the palletizer section to the band machine section during package forming work, and after the shrink film 9 is removed during package disassembly work. The parts that are most likely to fall during transport from the empty can discharge section to the empty can discharging section are the front row and the rear row in the traveling direction of the empty can group E1 on the uppermost stage.

On the other hand, in the embodiment, the uppermost empty can group E1
are placed on the folding partition plate 5, so the empty cans 3 in the front and rear rows are placed on the folding partition plate 5, as shown in FIG.
It is now placed on the bent portion 5a of the folded partition plate 5.

Therefore, the empty can 3 placed on the folded portion 5a is inclined inward, and its flange portion 3c comes into contact with the empty can 3 in the next row.

Therefore, even if the load is subjected to a force in the falling direction due to the inclination or vibration of the package, as long as the force is not excessive, the
Empty cans 3 that are tilted inward will not tilt outward in the direction of fall (in the direction of arrow A) beyond the vertical upright position, thereby preventing the empty cans from falling.

Furthermore, as described above, since the empty can 3 is inclined inward, the outwardly protruding flange portion 3c is retracted inward from the presser plate 6, as shown in FIG. state (retracted length M),
Damage to the flange portion 3c can be prevented during transportation (particularly during the operation of arranging a large number of multi-tiered empty can packages).

Next, a second embodiment shown in FIG. 6 will be described.

In this embodiment, the four edges of the folding partition plate 5 are bent upward to form bent portions 5a, 5a, 5.
This is an example using a partition plate formed with b and 5b.

In this example, since the tops of one of the empty cans 3 on the folding partition plate 5 and the empty cans 3 in the front row on all four sides are inclined inward, the empty cans 3 on the front row on all four sides It has the advantage of being able to prevent all falls.

In addition, in this example, the orientation of the package with respect to the traveling direction of the multi-tiered empty can packaging body forming line of the can manufacturing factory, and the orientation of the packaging body with respect to the advancing direction of the multi-tiered empty can packaging body disassembly line of the cannery are as follows. If the empty cans differ by 90 degrees (i.e., the empty cans that were in the front row or the last row during the package forming process will be in the rightmost or leftmost column during the package disassembly process; This is particularly effective when the empty cans that were in the row or the leftmost row become the front row or the last row during the dismantling of the packages. There is an advantage in that deformation of the flange portions of empty cans (empty cans forming the outermost rows on all four sides) can be prevented during arranging operations.

Although the embodiment of the present invention has been described above in detail with reference to the drawings, the specific configuration is not limited to this embodiment. For example, the three sides of the partition plate may be bent, etc. within the scope of the gist of the present invention. design changes and partition plate material changes (e.g., synthetic resin materials,
Metal materials, composite materials, laminated materials, etc.) are also included in the present invention.

(Effects of the invention) As explained above, in the multi-tiered empty can package of the invention, at least the partition plate on which the group of empty cans in the uppermost tier is placed is at least A folding partition plate is formed on the edges of two opposing sides to form an upwardly bent part so that the empty cans arranged in the front row of the group of empty cans can be placed in an inwardly inclined state. Although it is a highly practical method that uses a folding partition plate that can be obtained without increasing the number of parts by a simple bending process, it is easy to use when forming empty can packages or dismantling empty cans. The effect of preventing falling can be obtained.

Moreover, in the embodiment, in addition to the above-mentioned effects, the flange portions of the empty cans arranged in the front row can be located inside the presser plate, so that
It is possible to prevent the flange portion from being damaged in the event of a collision with other multi-tiered empty can packages or obstacles.
