DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for accumulating bags packed with contents causing a sinking phenomenon in a bag and packing them in one box.

[0002]

2. Description of the Related Art Powders and granules such as meriken powder, sugar, cement, and a spraying agent are sometimes put in a bag as shown in FIG. 9, for example. And the trunk of the bag swells as shown by the solid line in FIG. In addition, even in the case of bags containing the same contents, the size of the trunk, that is, the degree of swelling, is often not constant.

[0003] In many cases, bags containing the contents A ', which cause a sinking phenomenon in the bag, are packed in a group in a state of standing in a cardboard box or the like, but the size of the box is the size of the ruled line of the bag. In many cases, the width is set to an integral multiple of [the width of w and l in FIG. 9B], that is, the state where the trunk portion is not expanded [the state of the chain line in FIG. 9B]. When packing such bags in a group, the bags that are normally arranged in an upright state are horizontally pushed into a box bent into a U-shaped cross section as shown in FIG.

[0004]

However, since the body of the bag is bulged as described above, when these are arranged, bulging in the width direction [β ₁ + β in FIG.
₂ ] and the bulge in the longitudinal direction (β ₃ + β _{4 in} FIG. 9B) are accumulated in each direction, and are considerably larger as a whole than when the unbulged bags are arranged. Therefore, if a group of boxes are packed in a state in which the trunk portion of the bag is inflated, the entire box is also inflated as indicated by X 'in FIG. 14, and the flap cannot be stuck. for example,
Even if flaps can be attached, box X 'after sealing
Looks bad.

[0005] Usually, to solve this, the dimensions of the box,
The outer diameter is made larger than W and L in FIG. 12 to absorb the swelling of bags stored therein. However, if the dimensions and outer dimensions of the box are larger than the specified dimensions, extra space may be created inside the box due to the inflated state of the bag due to the sinking state of the contents in the bag. Bags may get stuck inside the box. In addition, the size of the box itself is increased, which leads to an increase in material costs. SUMMARY OF THE INVENTION An object of the present invention is to provide a method and an apparatus for stacking and packing which can solve such a drawback.

[0006]

In order to achieve the above-mentioned object, in the method of stacking and packing according to the present invention, the bag A containing the contents causing a sinking phenomenon in the bag is laid down from the upright position, The swelling of the torso portion that occurs when a part of the contents is moved to the space a existing in the upper part of the inside and is raised is reduced, and the bags are stacked while regulating the width, and then integrally raised. Then, the group is housed in a box while being clamped from the front and back.

In this case, as shown in FIG. 11, it is better to make the space a lower than when the bag A is laid horizontally.

In the above case, the bag A is laid down from the upright position, and a part of the contents is moved to the space a existing in the upper portion of the bag when the bag A is upright. After reducing the bulge of the torso, it is better to forcibly reduce the outer dimensions by clamping the torso of the bag from both sides.

[0009] On the other hand, in order to achieve the above object, the stacking and boxing device of the present invention is configured such that the bag A containing the contents causing the sinking phenomenon is laid down from the upright position ,

It is possible to perform the standing operation and the unloading operation of the bag after the stacking operation.

[0029]

An embodiment of the present invention will be described with reference to the accompanying drawings. FIG. 1 is an overall elevational view showing one embodiment of the stacking / boxing device of the present invention, and FIG. 1 and 2, 1 is
This is a transfer body for transporting the bag A in which the contents A 'which cause a sinking phenomenon in the bag are stored in an upright state. The body portion of the bag A on the transfer body 1 is inflated as shown in FIG. 9B because the contents A 'are sunk in the bag.

In this embodiment, a case will be described in which two bags are arranged side by side and two bags are arranged in four rows, that is, 2 × 4 and stored in one box. It is not limited only to 2 bags of 1 × 2 in one row
As described above, the present invention can be widely applied to a case where a large number of rows are provided.

A transfer body 2 is arranged so as to be orthogonal to the transfer body 1, and a transfer body 3 is directly connected to the transfer body 2. Further, at the place where the transfer body 1 and the transfer body 2 intersect at a right angle, the bag A containing the contents A 'which causes the sinking phenomenon is laid down from the upright state in the bag , and is present at the upper part in the bag.
When a part of the contents A 'is moved to the space a and set up,
Flip and the posture changing means B of order to reduce the bulge of the barrel portion has been disposed. By the operation of the body position changing means B, the bag A in the upright state can be laid down. When the bag A is standing, the contents A 'are sunk in the bag and the space a exists at the upper part as shown in FIG.
When this is laid down by the body position changing means B as shown in FIG. 10, a part of the contents A 'moves to the space a as shown in FIG. Can be reduced.

The embodiment exemplifies a case where the body position changing means B is a pusher as indicated by 4 in FIG. When the pusher 4 is used, not only can the bag A be laid down by simply pushing the lower part of the trunk of the bag A with this,
The bag can be placed on the transfer body 2. And
Since the bag in this case is pushed down by the pusher 4, the contents A 'can be leveled in the bag compared with the case where the bag is gently laid down by the vibration at that time.
Therefore, the bulge of the trunk portion can be further reduced as compared with the case where a part of the contents A 'is simply moved to the space a existing when the bag A is laid up by gently lying down. The body position changing means B is not limited to the one shown in the present embodiment. For example, the body position changing means B can be carried out by sandwiching the bag A in a standing state from both sides and rotating it.

The bag laid down by the body position changing means B (in the embodiment, the pusher 4) is sent forward by the transfer body 2 and the transfer body 3 directly connected thereto. As shown in FIG. Therefore, when the bag on the transfer body 2 is erected as shown in FIG. 11, the space a existing at the top of the bag is lower than when the bag is laid horizontally, and the contents A are transferred to the space a while being transported. 'Can be moved. Then, since part of the content A 'moves downward during the conveyance, the space is almost eliminated, and the bulge of the trunk portion can be further reduced or almost eliminated.

On the left and right sides of the transfer bodies 2 and 3, FIG.
挾圧hand stage shown in F in FIG. 2 are arranged. The holding means F is for holding the lying bag carried by the transfer bodies 2 and 3 from both right and left sides in the carrying direction, and is laid on the transfer bodies 2 and 3 by the operation thereof. Bags are clamped from the left and right in the transport direction,
The bulge of the torso portion can be further reduced.

In the embodiment, the clamping means F is constituted by a pair of vertical conveyors 5 and 5 arranged in the front-rear direction, which are disposed on the left and right in the running direction of the transfer bodies 2 and 3. The pair of left and right vertical conveyors 5 and 5 run in the direction of the arrow in FIG. Can be reduced. In the embodiment, the interval between the vertical conveyors 5 and 5 located on the near side (the left side in FIG. 2) is made wider at the inlet side and narrower at the outlet side. The interval between the pair of vertical conveyors 5 and 5 disposed in front of the vertical conveyors 5 and 5 (on the right side in FIG. 2) is the same as the interval on the outlet side of the pair of vertical conveyors 5 and 5 located in front of the vertical conveyors. I do the same. In this way, bags recumbent state of being conveyed by the conveying member 2 is sandwiched by the pair of vertical conveyors 5,5 which is located in front (left side in FIG. 2) that the width becomes gradually narrower, which After being transferred to the front transfer body 3, it is transported forward by being sandwiched between a pair of vertical conveyors 5 and 5 at the front (right side in FIG. 2).

The clamping means F is not limited to the one shown in the embodiment. For example, in the case where the width is regulated while the bag is stopped, the clamping means F is clamped by a pair of left and right clamping plates. This can be done by pressing.

Immediately before the end of the transfer body 3 (on the right side in FIG. 1), a receiving table 6 having a U-shaped cross section is disposed. This cradle 6
Is for temporarily receiving the bag material sent from the transfer body 2 with the restricted width, and sending it to the stacking means C (to be described in detail later). The bag material transferred here is the left and right side plates. The width is still regulated in 7,7. As shown in FIG. 3, the cradle 6 is rotatable about a shaft 9 by, for example, a cylinder 8. When the cradle is tilted as shown by a chain line in FIG. 3, the bag in the cradle 6 moves forward. It is moved to a certain stacking means C.

The stacking means C is for stacking bags of which width is regulated in a plurality of stages, and the width of the bags transferred here is still regulated by the left and right side plates 10, 10. The stacking means C shown in the embodiment basically arranges the receiving plate 12 so as to be at right angles to the bottom plate 11 in the shape of a pontoon,
This can be moved up and down with respect to the bottom plate 11. More specifically, the receiving plate 12 has a comb-like shape, and its protruding piece is inserted into a gap of the bottom plate 11 so that the receiving plate 12 can be moved up and down along the gap. There are two side plates 10, 10 on the left and right sides thereof.

In order to move the receiving plate 12 up and down with respect to the bottom plate 11, for example, as shown in FIG. 3, a rotatable screw rod 13 is disposed below the bottom plate 11 in parallel with the bottom plate 11. It is preferable to fix the protruding piece of the receiving plate 12 protruding from the gap of the bottom plate 11 to the back side of the threaded sleeve 14. When the screw rod 13 is rotated in the same direction by, for example, a motor 15, the sleeve 14 screwed to the screw rod 13 moves downward with respect to the screw rod 13, and accordingly, the receiving plate 12 gradually moves relative to the bottom plate 11. Is moved downward. FIG. 4 shows the situation in detail.
That is, the receiving plate 12 at the position shown in FIG.
By rotating the screw rod 13 in the same direction, as shown in FIG.
Go down one more step as shown. When the screw rod 13 is further rotated in the same direction as above, the receiving plate 12 at the position shown in FIG. 4 (c) is further lowered by one step as shown in FIG. 4 (d).

During this time, the bags A are successively laid down by the body position changing means B (in the embodiment, the pusher 4), and the bags A are successively transported forward by the transfer bodies 2 and 3, and the pressing means (the embodiment) is interposed therebetween. When the bags are intermittently transferred from the receiving table 6 to the stacking device C one after another while controlling the width by the pair of left and right vertical conveyors 5, 5), a plurality of Bags can be stacked. That is, every time a bag is transferred from the receiving table 6 to the stacking device C, the receiving plate 12 is lowered one step at a time, whereby a plurality of bags can be stacked by the stacking device C.

The method of lowering the receiving plate 12 one step at a time with respect to the bottom plate 11 is not limited to the means shown in the embodiment. For example, a cylinder may be attached to the bottom plate 11, The bottom plate 11 may be lowered one step at a time by intermittently operating the plate 12 in association with the plate 12.

Further, in the embodiment, the case where the stacking device C is obliquely placed on standby and the bags are thrown into the stacking device C obliquely to stack a plurality of bags obliquely is exemplified. The stacking device C may be kept on standby so that 12 becomes horizontal, and a plurality of bags may be stacked horizontally while the bags are charged horizontally.

As shown in FIG. 3, the stacking means C in the embodiment is designed to rotate in a plane about a vertical axis 16. In this way, after stacking a plurality of bags, by rotating the stacking means C about the vertical shaft 16, the stacked bags can be moved from the stacking position to a different position. .

If a plurality of the stacking means C are provided for the vertical shaft 16, the stacking means C for which the stacking operation has been completed is rotated with respect to the vertical shaft 16, and Can be arranged.

In order to rotate the stacking means C about the vertical shaft 16, in the embodiment, a sleeve 17 is rotatably fitted to the vertical shaft 16, and the base 17 of the bottom plate 11 is fitted to the sleeve 17. Is fixed so that the sleeve 17 can be rotated by some means, for example, by meshing gears.

An erecting means D for integrally raising the bags stacked by the stacking means C is disposed near the stacking means C. In this embodiment, as shown in FIG. An example of a case where the user moves up and down between positions will be described. By using the erecting means D as shown in the embodiment, it is possible to integrally raise a plurality of stacked bags by the stacking means C.

The standing means D shown in the embodiment will be described in detail with reference to FIG. Two levers 21 and 22 are fixed to a single horizontal shaft 20 rotatably supported so as to maintain a predetermined angle, and the other end of one lever 21 is connected to the cylinder 19. Pivotally attached to a rod 19a of The other end of the other lever 22 is engaged with the bottom of the stacking device C so as to be able to receive it. While the stacking means C is performing the stacking operation of the bag, the rod 19a of the cylinder 19 is moved to the position shown in FIG.
It protrudes as shown in (a). When the stacking operation by the stacking means C is completed, the cylinder 19 operates and the rod 19
5a is retracted as shown in FIG. 5B, and a lever 21 having one end pivotally connected thereto rotates about the shaft 20 in the counterclockwise direction of FIG. 5A. In response, the shaft 20 rotates in the counterclockwise direction of FIG. 5 and the lever 22 having one end fixed thereto.
Also rotates about the shaft 20 in the counterclockwise direction of FIG. Therefore, the tip of the lever 22 pushes up the stacking means C as shown in FIG. 5 (b) and keeps it horizontal. By this operation, the plurality of bags stacked by the stacking means C are integrally erected.

In the case of the embodiment, a plurality of bags stacked by the stacking means C in this manner can be integrally erected, but the erection means D is limited only to the case shown in the embodiment. Instead, for example, a plurality of bags stacked by the stacking means C may be sandwiched by two holding plates so that the plurality of bags are raised from the stacked state. In the case of the embodiment, the stacking means C is lifted by the operation of the cylinder 19 and the levers 21 and 22 in association with each other. The trochanter is mounted on the bottom of the means C, and the trochanter is engaged with the inclined surface of the cam, and the stepping means C is rotated. C may be lifted.

The plurality of bags stacked by the stacking means C are erected by the erecting means D as described above. At the position where they are erected, they are taken out in a group while holding them from front and rear. E is arranged. In the embodiment, a case is shown in which a plurality of stacked bags are at least erected at a position shifted by 90 degrees about the axis 16 from the stacked position.
Then, a case is shown in which the take-out means E is disposed at a position where the plurality of upright bags are moved further 90 degrees about the shaft 16 (indicated by a chain line in FIGS. 1 and 3).
In the embodiment, as shown in FIG. 6, the take-out means E is composed of two front and rear (left and right in FIG. 6) holding plates 23, 23 and means for moving these in the left-right direction of FIG. Is exemplified.

In the case of the embodiment, two right and left holding plates 23,
23 opens and closes symmetrically about each axis 24, and it is connected to two cylinders.
Perform at 25,25. That is, one end of each of the levers 26, 26 is fixed to the shaft 24, 24 of each of the two left and right holding plates 23, 23, and the other end of each of the levers 26, 26 is connected to the rod 25a of the cylinder 25, 25. Both are pivotally connected to 25a. Accordingly, when the rod 25a of one of the cylinders 25 (right side in FIG. 6) protrudes from the retracted position, the shaft 24 rotates in the clockwise direction in FIG. The holding plate 23 is closed as shown in FIG. When the rod 25a of the other cylinder 25 (left side in FIG. 6) is retracted from the protruding position,
The shaft 24 rotates in the counterclockwise direction via the lever 26, and the left clamp 23, which has been in the horizontal state, closes as shown in FIG.
Therefore, the plurality of bags raised by the raising means D are held by the holding plates 23, 23, and their length (the left-right direction in FIG. 6) is regulated.

When the two left and right holding plates 23, 23 are moved by the moving means, the upright bag can be taken out while standing. As shown in FIG. 6, the moving means in this embodiment comprises two holding plates 23, 23 mounted on one support 26 as shown in FIG. 6, and a block 28 sliding on a guide rod 27 arranged in the left-right direction. Support 26
Is fixed. When the block 28 is moved by a cylinder (not shown), for example, along the guide rod 27, the two left and right holding plates 23, 23 move along with the support 26 along the guide rod 27.
A plurality of bags sandwiched between 23 and 23 can be taken out in a group while standing.

Although the take-out means E is not limited to the case shown in the embodiment, at least both ends (left and right sides in FIG. 6) of a plurality of bags are formed in a certain shape as in the case of using the holding plate 23. It is desirable to be able to regulate the length (the left-right space in FIG. 6). In addition, as described above, when two holding plates are used as the erecting means D,
The pair of holding plates can be used as they are as the holding plate 23 of the extracting means E. However, when the two holding plates are used in common for the erecting means D and the unloading means E, the two holding plates have both the operation of erecting a plurality of bags and the operation of taking out the plurality of bags after the erecting. It is necessary to keep it, and it may be complicated mechanically.

In the embodiment, as described above, the case where the stacking means C is rotated in a plane around the vertical axis 16 is exemplified. A plurality may be attached at intervals. In this way, the stacking means C moves linearly differently from the case of the embodiment, and performs the stacking operation and the standing operation and the unloading operation of the bag after the stacking operation at different positions on the same straight line. be able to.

For example, in the case of using the above-described stacking and boxing device to stack and pack the bags containing the contents A 'which cause a settling phenomenon in the bag, the width of the bag (FIG. 9B)
9 (b), and the length [1 direction in FIG. 9 (b)] are restricted to at least w and l in FIG. 9 (b).
Even if these are arranged side by side and packed in a box, as shown in FIG. 12, they will fit exactly in a predetermined position of a box having a width W and a length L. Focusing on this point, in the stacking and boxing work using the above-mentioned device,
At least at the stage after the end of the unloading operation, the bags are regulated so that the total width W ′ (FIG. 7) of the plurality of stacked bags is equal to or less than W in FIG. The bags are regulated such that the overall length L '(FIG. 7 ) of the plurality of bags is less than L in FIG. As a result, a plurality of bags, each containing therein the contents A 'which cause a sinking phenomenon in the bag, can be stored exactly in a box of a predetermined size W × L in a state of being erected and arranged as shown in FIG.

According to the first aspect of the present invention, a plurality of bags, each of which stores contents causing a settling phenomenon in the bag, can be stored in the box in a state where a plurality of bags are stood up and arranged. There is no danger of interfering with the sealing operation, and it is possible to eliminate the disadvantage that the box after sealing is swollen and the appearance is bad.
