Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial field of use" The present invention relates to an article storage device for storing articles in a box having a rear side flap, and more specifically, folding the rear side flap forward in the transport direction. The present invention relates to an article storage device that is bent to store articles.

"Prior Art" Conventionally, as an article storage device, a box transfer conveyor that transfers a box member having a front side flap and a rear side flap, and a pair of front guide members provided on one side of the box transfer conveyor. The rear guide member is circulated and conveyed in the vertical plane, and both guide members are inserted between both side flaps when the guide members are rotationally transferred from the lower side not engaged with the side flap to the upper side engaged with the side flap. A delivery conveyor, an article transporting conveyor that is provided on the opposite side of the delivery conveyor from the box transporting conveyor and that transports articles, and an article transported by the article transporting conveyor is inserted into the box member via the both guide members. And an article extrusion mechanism to be arranged further downstream of the delivery conveyor,
It is known that a rear side flap from which the rear guide member is detached is provided with a side flap bending mechanism that bends the rear side flap to the front side in the transport direction.

[Problems to be Solved by the Invention] In the above-described article storage device, the guide members inserted between the front and rear side flaps allow both side flaps to be slightly spread forward and backward in the transport direction, particularly in the rearward direction. When the rear side flaps are widely pushed rearward due to the positional deviation between the side flaps and the rear guide member that is in contact with the side flaps, the rear side flaps are bent. In addition to this, when the article storage device is abnormally stopped for some reason, that state continues for a long time, resulting in stronger folding.

When the rear side flaps are largely pushed rearward, the side flap folding mechanism that bends the rear side flaps to the front side cannot properly engage with the rear side flaps, and the front side of the rear side flaps is prevented. Bending to the side may be incomplete or impossible.

[Means for Solving the Problems] In view of such circumstances, the present invention provides a rear guide member that engages with the rear side flaps with a bending member located rearward of the rear side flaps. When the guide member is rotationally transferred from the upper side that engages with the rear side flap to the lower side that does not engage with the rear side flap, the rear side flap is bent forward by the folding member in the transport direction.

[Operation] According to the above-mentioned configuration, even if the rear side flap is provided with a fold so that the rear side flap remains largely expanded to the rear side in the conveying direction, the folding member causes the rear side flap to move the rear side flap toward the front side in the conveying direction. Since it can be bent to correct the fold, it is possible to reliably bend the rear side flaps forward by the side flap folding mechanism in the transport direction, and therefore, it is possible to prevent defective products from occurring. Can be prevented.

[Examples] The present invention will be described below with reference to the illustrated examples. In Fig. 4, the containers 1 grouped in 5 rows and 2 columns are as follows.
The article conveying conveyor 2 conveys the front and rear of the article conveying conveyor 2 while sandwiching the guide means 3 therebetween.
The container 1 conveyed while being sandwiched by the pair of guide means 3 is conveyed along the pair of guide means 3 by the pushing member 5 of the article pushing mechanism 4 provided on one side of the article conveying conveyor 2. It is designed to be extruded in a direction orthogonal to.

On the side where the container 1 is extruded, one side of the delivery conveyor 6 is disposed adjacent to the article transport conveyor 2, and the box transport conveyor 7 is disposed on the other side of the delivery conveyor 6. As shown in FIG. 3, the box member 9 conveyed by the box conveyer 7 has a rear side portion 10, a bottom portion 11, a front side portion 12, a lid portion 13 and an insertion portion 14 which are successively formed.
The rear side flaps 15 are provided on both sides of the rear side portion 10 and the front side flaps 16 are provided on both sides of the front side portion 12.
The lower flap 17 is provided on both sides of the bottom portion 11, and the upper flaps 18 are further provided on both sides of the lid portion 13.

As shown in FIG. 4, a supply mechanism 20 for the box member 9 is provided at the upstream end position of the box conveyor 7, and the supply mechanism 20 is a flat carton blank before being molded into the box member 9. The front side 12 and the rear side 10 with respect to the bottom 11.
Is bent upward and formed into a U-shape, and the front side portion 12 is supplied to the clamp mechanism 21 provided at every predetermined interval of the box conveyor 7 with the front side in the conveying direction.

The lower flaps 17 on both sides of the box member 9 gripped by the clamp mechanism 21 are bent downward by fixed guides (not shown) provided on both sides in the transport direction, as the box transport conveyor 7 transports the lower flaps. Further, the fixed guide allows the sheet to be conveyed while maintaining the state.

As shown in FIG. 3, the delivery conveyor 6 includes a pair of left and right endless chains 23 (only one is shown) that are hung on sprocket 22, 22 provided at both ends in the transport direction and circulate in a vertical plane. It is equipped with, between those endless chains 23,
A guide means 24 having a U-shaped cross section is provided at the same intervals as the box member 9 conveyed by the guide means 3 of the article conveying conveyor 2 and the box conveying conveyor 7 and having a pair of front guide members 24a and rear guide members 24b. ing.

On the delivery conveyor 6 side of the box transfer conveyor 7, a fixed guide 25 is provided at a required position on the upstream side of the delivery conveyor 6, and by the fixed guide 25, the front side flap 16 and the rear side flap 15 of the box member 9 are provided. Bend each of the rear and
By separating the side flaps 16 and 15 from the fixed guide 25, the side flaps 16 and 15 are sequentially returned to their original lateral positions by their elasticity.

When the front side flap 16 separates from the fixed guide 25 and returns to the original lateral position by its own elasticity, the front guide member 24a and the rear guide member 24b rotate around the sprocket 22 and engage with the side flap. It is adapted to be transferred from the lower side which does not fit to the upper side which engages with the side flap.

Then, when the rear guide member 24b located at the rear is in the upper position, the rear side flaps 15 are subsequently separated from the fixed guides 25, and the rear side flaps 15 are elastically moved to the original lateral position. When it returns and comes into contact with the rear surface of the rear guide member 24b, the front guide member 24a and the rear guide member 24b are inserted between the front side flap 16 and the rear side flap 15.

The distance between the inner surfaces of the pair of guide members 24a and 24b is set to be substantially the same as the distance between the inner surfaces of the pair of side flaps 15 and 16, and therefore the article pushing mechanism 4
The container 1 extruded between the pair of guide members 24a and 24b from between the pair of guide means 3 of the article conveying conveyor 2 by the extruding member 5 of the article conveyor 2 smoothly without being interfered by the side flaps 15 and 16. It can be inserted between the front side part 12 and the rear side part 10.

On the other hand, since the distance between the inner surfaces of the guide members 24a and 24b and the distance between the inner surfaces of the side flaps 15 and 16 are set to be substantially the same, the guide members 24a and 24b have side flaps 15 and 16 respectively.
When inserted between them, the front side flap 16 and the rear side flap 15 are pushed and spread forward and backward by the guide members 24a and 24b, respectively (first section).
See figure).

Then, as described above, when the rear side flap 15 is largely pushed backward, the side flap folding mechanism that bends the rear side flap 15 to the front side.
26 may not be able to be properly engaged with the rear side flap 15.

That is, as shown in FIG. 1, the side flap bending mechanism 26 is provided with a fixed guide 27 provided along the conveyance direction of the box conveyor 7 and having its upstream end expanded and a rotation center of the base. Is provided with an L-shaped movable arm 28 that is intermittently reciprocally rocked at a predetermined timing between a non-actuated position indicated by a solid line and an actuated position indicated by an imaginary line.

And a front side flap of the box member 9 accommodating the container 1
16 is bent rearward in the conveying direction by the fixed guide 27, and the rear side flap 15 is bent forward by the tip of the movable arm 28 which is operated at a predetermined timing, and the fixed guide 27 is fixed. Is transported while being maintained in that state.

However, the rear side flaps 24b and the rear side flaps 15 are misaligned due to misalignment and the like.
If 15 remains largely expanded backward, the tip of the movable arm 28 cannot engage with the rear side flap 15, or even if it engages, the rear side flap 15 does not move.
It could not be smoothly bent forward in the transport direction, and the rear side flaps 15 could be damaged.

Therefore, in this embodiment, the rear side flaps are
The rear guide member 24b engaging with 15 is provided with a bending member 29 located rearward of the rear side flap 15.

The bending member 23 is arranged at a required distance behind the rear guide member 24b and at a required height position.
As shown in FIG. 3, the rear side flap 15 is returned to its original lateral position by its own elasticity, and the rear guide member 24b is moved.
After contacting the rear side flaps 15, the rear side flaps 15 are further rotatably transferred from the lower position to the upper position in the rear position, whereby the rear guide member 24b.
The rear side flap 15 can be located between the folding member 29 and the bending member 29.

On the other hand, when the guide means 24 is rotatably transferred from the upper side to the lower side at the downstream end position of the delivery conveyor 6, the front guide member 24a and the folding member 29 respectively move the front side flap 16 and the rear side flap 15 respectively. Since it bends to the front side in the transport direction (see FIGS. 1 and 2), even if the rear side flaps 15 are largely pushed backward, the bending members 29 cause Therefore, the rear side flap 15 can be reliably bent forward by the movable arm 28 in the transport direction.

In addition, the rear side flap on the side opposite to the insertion side of the container 1
The front flap 15 and the front side flap 16 are folded at a position slightly upstream of the insertion position of the container 1 into the box member 9 by a side flap folding mechanism 30 having the same configuration as the side flap folding mechanism 26. It is like this.

Then, at the position downstream of the side flap bending mechanism 26, the lid portion 13 and the insertion portion 14 of the box member 9 are provided.
Is bent and the insertion part 14 is inserted inside the rear side part 10, and after the glue is applied to the surfaces of both side flaps 15 and 16, the lower flap 17 and the upper flap 18 have their sides. The box containing the container 1 is completed by being polymer-bonded onto the flap.

[Advantage of Invention] As described above, according to the present invention, the rear side flap can be bent forward by the bending member provided on the rear guide member in the conveying direction. It is possible to surely bend the rear side flaps forward in the transport direction, and thus it is possible to effectively prevent the generation of defective products.
