Description

  The present invention relates to a method for accumulating concave shaped bodies, an apparatus therefor, and an accumulated body of concave shaped bodies.

As a cup-shaped container having a flange portion, a configuration is known in which a stack portion that becomes a step is provided in the container body so that each container can be easily separated from a stacked state (for example, Patent Document 1).
In a container having such a stack part, when a plurality of the containers are stacked, the containers are in a state of running on the stack part. For this reason, even if uneven thickness has arisen in a container, even if it piles up two or more, it will not be gradually inclined and piled up by uneven thickness. Therefore, a stable stacked state can be obtained, and even a plurality of stacked states can be stably stored and transported.

JP 2005-280757 A

However, in a container provided with a stack part, a stable stacking state can be obtained even in many containers regardless of uneven thickness, but in the stacked state, the stack part is in a state of climbing, so there is a gap between the containers. Will increase and the height of stacking will be higher. For this reason, since it corresponds to preservation | save and conveyance, the amount piled up will be reduced, and there exists a possibility that efficient preservation | save and conveyance may become impossible.
On the other hand, when containers are formed without providing a stack part, the height of stacking can be reduced, so it is possible to increase the amount of stacking during storage and transport, but efficiency can be achieved, but the amount stacked due to uneven thickness of the container As the number increases, there is a risk that it will be gradually tilted and stable storage and transportation may not be possible.

It is a figure which shows the container which concerns on one Embodiment of this invention, Comprising: The perspective view which shows the state which opened the cover body. The conceptual diagram which shows the accumulation | stacking apparatus which accumulate | stores the concave-shaped molded object of the said container.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
In this embodiment, the container provided with the concave shaped product of the present invention is illustrated, but the present invention is not limited to this.

(Configuration of easy-open container)
1 and 2, the easy-open container 1 includes a container body 2 as a concave shaped body and a sheet-like lid body 3.
The container body 2 has a substantially rectangular tray-shaped recess 23 having a predetermined depth. A flange portion 25 extends from the periphery of the substantially rectangular opening 24 of the recess 23 so as to project outward. The recessed part 23 is not provided with a lower neck stack part as a step in the body part 23B provided continuously with the periphery of the bottom part 23A.
In the easy-open container 1, the flange part 25 and the lid 3 placed on the flange part 25 with respect to the opening 24 are heat-sealed to form an annular heat-seal part 26. The inside is sealed. Further, a circumferential notch 27 is formed in the container body 2 by cutting with respect to the inside of the heat seal portion 26.

In manufacturing the easy-open container 1, for example, a sealing device including an annular sealing disk is used.
In order to fuse the flange portion 25 of the container body 2 and the lid body 3 so that the easily openable container 1 is in a sealed state, the lid body 3 is overlaid on the flange portion 25 of the container body 2. Heat sealing is performed by pressing an annular sealing disk in a heated state of the sealing device from the upper surface.

(Accumulator for container body)
Next, an accumulation device for accumulating the container main body will be described with reference to the drawings.
In addition, in this embodiment, although the structure which shape | molds four container main bodies 2 by 2 operation | movements by 2 operation | movements is illustrated, it is not this limitation.
FIG. 2 is a conceptual diagram showing an accumulation device for accumulating container bodies.

  As shown in FIG. 2, the stacking device 4 includes a feeding unit (not shown) that feeds the sheet 5 in the horizontal direction, a molding unit 41 that forms a plurality of container bodies 2 from the fed sheet 5, and a cutting that cuts out the container body 2. The part 42, the moving part 43 which moves the cut-out container main body 2, and the stacking part 44 which piles up the moved container main body 2 sequentially are provided.

The forming unit 41 includes a mold having a lower mold and an upper mold (not shown), and is arranged in two rows along the sheet feeding direction A from the fed sheet 5 along the width direction orthogonal to the sheet feeding direction. Two rows of four container bodies 2 are formed to obtain a shaped sheet 5A in which the container bodies 2 are formed in two rows.
In addition, as a shaping | molding method, various shaping | molding methods, such as shaping | molding, cooling a preheated sheet | seat with a metal mold | die, heating with a heated metal mold | die, are applicable. In particular, vacuum or vacuum / pressure forming is particularly effective for these methods because a so-called draw-down in which the melted sheet 5 hangs down causes uneven thickness.

The cutting part 42 includes an annular cutting blade (not shown) corresponding to the outer peripheral edge of the flange part 25 of the container main body 2, and cuts two rows of container main bodies 2 for each row, that is, operates two container main bodies 2 in one operation. And is cut out downward in the thickness direction of the shaped sheet 5A.
In addition, there is some distance between the molding part 41 and the cutting part 42, and the shaped sheet 5A is in a loose state. That is, while the molding unit 41 is molding the four container main bodies 2 in two columns and two rows, the shaping sheet 5A is formed at the timing of performing the punching of the two container main bodies 2 in each row twice. 41 is sequentially fed out. Since the forming process is performed on the upstream side where the cutting is performed twice and the sheet 5 is not fed out, the shaped sheet 5A is in a slack state between the forming part 41 and the cutting part 42. The feeding of the shaping sheet 5A is adjusted. The slackness of the shaped sheet 5A may be relaxed as it is due to its own weight, or the feeding may be adjusted by a dancer roller or the like.
And the lattice-like sheet | seat after the container main body 2 is cut out is wound up separately, and is processed.
In addition, as a method of cutting, in addition to cutting with a cutting blade, cutting may be performed with a laser beam or water pressure. Moreover, you may cut out one for every row | line | column with one cutting blade. Further, the cutting blade is not limited to an annular blade, but a cross blade, a blade constituted by a plurality of blades that cut along the feeding direction of the sheet 5 and a blade that cuts in the width direction, and rotation. Various cutting methods such as blades can be applied.

The moving unit 43 receives the container body 2 punched out by the cutting unit 42 by, for example, a belt conveyor, and is arranged at a destination in the moving direction B along the direction perpendicular to the feeding direction A of the sheet 5. Move to the stacking portion 44.
The movement to the stacking unit 44 is performed by, for example, continuously operating the belt conveyor to continuously move the container body 2 falling from the cutting unit 42, detecting the fall of the container body 2, and detecting the fall The belt conveyor may be intermittently operated. Further, when two rows are formed by the molding unit 41, two rows are punched, and the container main body 2 punched in the second row is overlapped on the container main body 2 that has been dropped on the belt conveyor by punching one row, and is fed out. You may make it carry out the pile which absorbed the thickness deviation in the direction A, then move to the pile part 44, and may make it pile up further.
The moving unit 43 is not limited to a belt conveyor, and is moved while being suspended by suction, etc., is moved by being slid by its own weight like a chute, is moved by vibrated raising, and various movements. The method can be applied.

The stacking unit 44 includes guides (not shown) that receive and stack the container main bodies 2 that are moved one by one by the moving unit 43 and stack the container main bodies 2 in a predetermined number.
As the guide, for example, various configurations that guide the container body 2 that is moved by the belt conveyor of the moving unit 43 and falls from the belt conveyor to a predetermined stacking position can be used. Further, a cardboard box that houses the stack 6 may be used as a guide.
In addition, the stacking unit 44 is provided with a sensor, a counter, or the like that detects that a predetermined number of container main bodies 2 are stacked, and is configured to separately carry out the aggregate 6 that is an assembly of the predetermined number of container main bodies 2. This is preferable because it can be automated. Further, when it is detected that a predetermined number of stacks have been completed, a series of steps may be temporarily stopped to notify that effect.

(Method for collecting containers)
Next, a method for stacking the container body 2 by the stacking device 4 will be described.
The wound sheet 5 is fed out horizontally by the feeding unit and is sent to the forming unit 41 while being heated by hot air or the like. Then, the molding process of obtaining the shaped sheet 5A is performed by molding the four container bodies 2 in two rows and two rows on the sheet 5 by, for example, vacuum or vacuum / pressure forming with the mold of the molding unit 41.
By this molding, the thickness becomes thickest at the center position where the four container main bodies 2 are close to each other, resulting in an uneven thickness where the peripheral portions of the four container main bodies 2 are the thinnest.

After this forming step, the shaped sheet 5A is fed to the cutting portion 42, and a cutting step is performed in which the container main body 2 formed by a cutting blade (not shown) is punched out line by line and two container main bodies 2 are cut out. . The cut out container body 2 is dropped onto the moving unit 43 positioned below.
And the moving process which moves the container main body 2 to the stacking part 44 along the moving direction B by the moving part 43 is implemented.
The container main body 2 moved by the moving process of the moving unit 43 is in a state of being sequentially stacked in different rows in the molding unit 41. Specifically, the container main body 2 moved by the moving unit 43 is the first column of the first row, the second column of the first row, the first column of the second row, the second column of the second row,. It will be in a state of being stacked in the order of. From this, the thick portion and the thin portion due to uneven thickness of the first container body 2 and the second container body 2 stacked next are stacked in the same position without overlapping. For this reason, the container main bodies 2 that are sequentially stacked do not gradually tilt and accumulate due to the overlap of uneven thickness, and are straight and stably stacked.

Then, after the container bodies 2 are stacked in a predetermined number, they are packed as a single assembly as the integrated body 6 and sequentially stored and transported.
Moreover, when taking out the container main body 2 from the accumulation body 6 one by one, for example, it can be taken out one by one easily by hooking a jig, a rotating body, or the like on the outer peripheral edge of the flange portion 25.

(Effect of embodiment)
As described above, in the above embodiment, after the container body 2 cut after being formed into two rows on the fed sheets 5 is moved in the moving direction B perpendicular to the feeding direction A of the sheets 5, In the destination, the stacking unit 44 is stacked.
Accordingly, the container main bodies 2 formed in different rows are in a state of being alternately stacked, for example, in the first row, the second row, the first row, the second row,. For this reason, uneven thickness occurs in the container body 2 by molding in two rows, but the uneven thickness positions are sequentially stacked at different positions, so that the stacked states with overlapping uneven thickness positions are inclined as they are stacked. It is possible to prevent the inconvenience of end. Therefore, the container main body 2 can be straightly and stably stacked without being formed into a specific shape such as a lower neck stack portion to absorb and accumulate uneven thickness. Therefore, the stacked body 6 in which the container main bodies 2 are stacked can be stably stored, stored, and transported.

And in the said embodiment, the container main body 2 which extended the flange part 25 from the periphery of the opening 24 of the recessed part 23 is shape | molded.
For this reason, for example, the container main body 2 can be easily taken out one by one from the accumulation body 6 by hooking a jig or a rotating body on the outer peripheral edge of the flange portion 25.

Moreover, in the said embodiment, the container main body 2 which does not have a neck lower stack part is shape | molded.
For this reason, generation | occurrence | production of a clearance gap between the container main bodies 2 of the piled-up state is suppressed, the pile height can be restrained lower, and the volume in a lamination | stacking state becomes small. Therefore, the stacked quantity at a predetermined height can be increased, and the overall dimensions of the aggregate 6 at a predetermined quantity can be reduced, so that the efficiency of storage, storage and transportation in a stacked state can be improved.

Furthermore, in the cutting part 42, the container main body 2 is cut out by punching.
For this reason, since the container main body 2 is cut downward with respect to the shaping sheet 5A, the punched container main body 2 can be moved in a moving direction B with a simple configuration such as a belt conveyor, and the stacking device 4 The configuration can be easily simplified.

Accordingly, the description of the materials, layer structures, and the like disclosed above is exemplary for easy understanding of the present invention, and does not limit the present invention. Descriptions with names excluding some or all of the limitations are included in the present invention.

For example, a configuration in which molding is performed in two columns and two rows and punched out one by one is illustrated, but any configuration can be applied as long as the molding is performed in two or more columns in which uneven thickness occurs. Moreover, you may shape | mold not only in the case of shape | molding for every 2 rows but for every row or several rows | lines of 3 or more rows. And it is applicable not only to vacuum or vacuum / pressure forming but also to various forming methods.
