Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is a method for stacking a large number of small bags filled with contents and conveying and supplying them sequentially on a stacking pallet and storing them in an outer bag. , relates to an automatic packaging method and apparatus for automatically packaging the outer bag by sealing the opening thereof.

[Prior Art] When packaging granules 1, for example, rice, a predetermined amount, for example, 10 kg,
It is common to weigh and pack in 20 kg units. However, in some cases, it may be desired to weigh and fill packaging in small units of several kilograms.

For example, in the case of rice, small bags of about 2 kg are preferred because families are becoming smaller, the amount eaten at one time is smaller, and there is less storage space. The larger the size, the easier it is to handle during transportation. In other words, when loading and unloading onto a truck, etc.
Since the handling unit is large, the number of items to be handled is small and the work can be done in a short time.Also, since each bag is large, it is easy to stack them, and moreover, they can be stacked stably and there is no risk of the load collapsing. few.

However, in the case of small bags, there is a problem in that they are not easy to handle during transportation. In other words, when planting and unloading onto a truck, etc., the handling unit is small, so the number of bags to be handled is large, which takes a long time, and since each bag is small, planting is not easy. Moreover, the stacking is unstable and there is a risk of the cargo collapsing.

Therefore, an automatic packaging machine has been proposed that solves the above problem by storing multiple small bags in a large outer bag and handling them as a single bag during transportation (Japanese Patent Application Laid-Open No. Similar automatic packaging machines have already been put into practical use for powders such as salt and sugar, and have shown excellent results.

[Problems to be Solved by the Invention] However, the conventional automatic packaging machine proposed above has a problem in that it is difficult to apply to packaging grains such as rice.

In other words, when powders such as salt are packed in bags and compressed, they appear to be solidified to some extent, so it is difficult to insert them into outer bags,
Since the shape of the pouch does not collapse when the opening of the outer bag is sealed, it can be handled without special consideration. On the other hand, granules such as rice do not exhibit such properties and cannot maintain a fixed shape. Therefore, in the conventional automatic packaging machine described above, it is difficult to insert the grains into the outer bag or open the outer bag. During sealing, etc., the shape of the pouch may collapse, resulting in the interruption of these operations. Therefore, even with automatic packaging machines, it is necessary for one worker to constantly monitor the work status, which is inconvenient.

Therefore, a fully satisfactory automatic packaging device for grains such as rice has not been put to practical use to date.

The present invention has been made to solve the above problems, and when inserting into an outer bag or sealing the opening of the outer bag,
Taking into account the properties of the granules that cause the sachets to collapse, this system allows for smooth packaging without interrupting each of these operations, and eliminates the need for workers to constantly monitor the work status, making it possible to fully automate the process. The purpose of the present invention is to provide an automatic packaging method and device for packaging.

[Means for Solving the Problems] The above-mentioned means for solving the problems of the first invention of the present application is to arrange a large number of small bags filled with contents and sequentially conveyed and supplied on a pallet, and then to arrange the pouches in the arranged state. In an automatic packaging method in which the package is placed in an outer bag, the opening of the outer bag is sealed, and the bag is automatically packaged. Insert a guide board to move the bag, press the group of small bags arranged on the pallet □, move them from the pallet to the guide board, insert the bag into the outer bag along the guide board, and insert the bag. The outer bag is pressed from the outside and the opening to shape it, and then the opening of the outer bag is folded in, and the glued part to which glue has been applied in advance is pressed against other parts to temporarily seal it. After stopping,
It is characterized by applying strong pressure to the glued portion to firmly seal the opening of the outer bag.

Further, a second invention of the present application is an apparatus used for carrying out the automatic alignment packaging method of the first invention, and as a means for solving the problem.

One end is positioned on the stacking pallet and the other end is inserted into the open outer bag, and a guide plate that smoothly inserts the stacked small bag groups into the outer bag and presses the stacked small bag groups. a pouch inserting means having a suppression mechanism for inserting the pouch into the outer bag along a guide plate; and a shaping mechanism for shaping the pouch inserted into the outer bag by pressing it from the outside of the outer bag and from the opening. a folding mechanism for folding in the opening of the outer bag; a first pressing section for temporarily sealing the glued part to which glue has been applied beforehand by pressing it against another part; and a second pressing part for strongly pressing the glued part. and a gluing mechanism for firmly fixing the outer bag opening and sealing the outer bag opening.

[Function] In the present invention, a guide plate is inserted into the opened outer bag to smoothly guide the stacked groups of small bags into the outer bag.

Therefore, by pressing the above-mentioned stacked pouch groups,
It can be inserted smoothly into the outer bag along the guide board. If the friction between the pouch and the outer bag is large, the pouch may get caught in the middle of the outer bag, causing the stacked items to collapse, which is prevented in the present invention by such means.

Further, in the present invention, the pouch group is shaped by pressing from the outside of the outer bag and the opening. In other words, in the case of a single grain, unlike powder, the shape of the pouch changes freely, so when it is inserted into the outer bag, the arrangement may be disordered, but in the present invention, this can be solved by shaping the outer bag. To prevent.

By shaping the outer bag in this way, the opening of the outer bag can be folded in neatly, and the glued portion can be well bonded.

In order to simplify the process, the opening of the outer bag is sealed by applying glue to the glued part in advance and pressing the glued part to other parts to adhere them. Now, instead of sealing all at once, first, the glued part is pressed against other parts and lightly adhered to temporarily seal the part for positioning.After this, the glued part is pressed hard and the outer bag is sealed. Secure the opening firmly.

The control section 900 shown in the above configuration requirement (i) includes a feedback control section and a sequence control section.

The former mainly controls the operation of the alignment means 100, and the latter mainly controls the operations of other parts.

<Operation of the embodiment> The operation of the embodiment will be explained with reference to the above figures.

The small bags P filled with rice are sequentially delivered at appropriate intervals from a supply section (not shown) and transported by a conveyor 101.

When the photoelectric detector 105 detects that the pouch P has entered the exit side of the conveyor 101, the alignment conveyor 104 is driven by a command from the control unit 900, and after receiving the pouch P, it stops and waits. state. After that, when the next pouch P reaches the exit side of the transport conveyor 101, the alignment conveyor 104 is driven in the same way as above to receive the pouch P,
Stop. As a result, two pouches P are arranged in alignment on the alignment conveyor 104.

When the control unit 900 detects this state using the photoelectric detector 105 at the rear end of the alignment conveyor 104, it instructs the air cylinder 203 of the pouch holding mechanism 202 waiting on the alignment conveyor 104 to send air pressure. This results in
The rod 204 protrudes and lowers the suction cups 205 and 2013 to abut the pouches P on the alignment conveyor 104, respectively. Further, according to a command from the control unit 900, the suction cups 205 and 20B are connected to a vacuum device, and the pouch P
aspirate. Then, air pressure is sent to the air cylinder 203, and the rod 204 is moved back to move the suction cups 205 and 20.
6 rises. The pouch holding mechanism 202 moves the stacking pallet 2 along the moving rail 201 by a drive device (not shown).
Move to a position above 0e. Here, air pressure is sent to the air cylinder 203 according to a command from the control unit 900,
The rod 204 protrudes, lowers the suction cups 205 and 206, and places the pouch P on the planting pallet 209.

By repeating the above operations, the stacking pallet 209
Plural rows of pouches P are stacked on top. This stacking pallet 2
In the case of one example, the pouch P arrangement pattern on 03 is the second pouch P arrangement pattern.
As shown in the figure, they are arranged in three layers: bottom two rows, middle one row, and top two rows. The arrangement is performed in the numerical order shown in FIG. 5. This arrangement pattern is written in advance in the sequence program of the control section 900. Therefore, the arrangement pattern can be changed by changing this program.

The number of pouches arranged and the number of pouches arranged are appropriately set depending on the relationship between the size and shape of the pouches and the size and shape of the outer bag.

When a predetermined number of pouches P are stacked on the stacking pallet 209, 1
An air cylinder (not shown) operates, and the regulation plate 207,
208 are rotated inwardly so that they are almost perpendicular to each other,
The pouch group P is compressed and regulated from the side to collapse the gaps between the pouches 2 and achieve high-density stacking.

On the other hand, in the outer bag supply unit 301, the suction conveyance mechanism 304 operates the air cylinder 30θ in response to a command from the control unit 800.
The vacuum suction section 305 is brought into contact with the main surface Ba of the outer bag B placed at the top, and is further brought into close contact with the main surface Ba of the outer bag B by a vacuum device (not shown). After this, the suction conveyance mechanism 304 moves the air cylinder 30B
When activated, it rises and pulls up the adsorbed outer bag B.

At this time, the next outer bag B stacked below the outer bag may be attached to the outer bag mainly at the glued part and pulled up together. In this embodiment, this is separated. Therefore, a separating knife 308 disposed beside the outer bag supply section 301 rotates horizontally (approximately 90 degrees), and a knife 309 separates the upper and lower outer bags. In addition, the air nozzles 3 and 2 eject air in the vertical direction to assist in lifting the outer bag B to be taken out, and also to assist in lifting the outer bag B to be taken out.
This prevents it from lifting up and ensures that only one piece can be taken out.

The suction conveyance machine 4R304 moves along the moving rail 302 to the pouch insertion position while adsorbing the pulled-up outer bag B, and descends by the operation of the air cylinder 306, and transfers the lower surface Bb of the outer bag opening to the suction cup 401. Have someone attend the meeting. Then, in response to a command from the control unit 900, the suction hole 402 of the suction cup 401 is activated to suction the lower surface Bb of the outer bag, and the suction conveyance mechanism 304 rises while adsorbing the outer bag-like surface Ba. Separate the upper and lower surfaces Ba and Bb of the outer bag.

At this time, by blowing out air from the air nozzle 403, the glue applied to the opening of the outer bag BOR is prevented from coming into contact with each other or other parts, making opening easier. Furthermore, by blowing out hot air from the air nozzle 403, the glue applied to the opening of the outer bag B can be softened, making subsequent gluing easier and more reliable.

Next, in response to a command from the control unit 900, an air cylinder (not shown) is operated, and the guide fi 501 moves the stacking pallet 2
It protrudes from the lower surface of 09 and enters into the middle part of the open outer bag B. In this case, if the outer bag B has low rigidity and is easy to bend, as shown in FIG. It may also be designed to prevent the material from sagging.

In this state, the bag receiving plate 801 is arranged on the lower side of the outer bag, and the outer bag B has the suction hole 6 provided in the bag receiving plate 601.
It is fixed by suction by 04. In addition, at this time, one bag receiving plate 80
The bottom plate 602 of No. 1 is in an open state.

Subsequently, the air cylinder 505 of the pressing mechanism 5L' is operated, and the pressing plate 503 is brought into contact with one end side of the stacked pouch group P to press the pouch group P and close the opened exterior. Move it towards bag B.

Each pouch P is sequentially moved from the stacking pallet 209 onto the guide board 501 and inserted into the outer bag along the guide 1501. At this time, since the upper surface of the guide 1501 has a smooth surface, the friction with the pouch group P is reduced, and no catching occurs due to friction, so that the arrangement does not collapse due to this.

In this way, when the small bag group P is inserted into the outer bag B, the guide plate 501 retreats to the lower surface of the stacking pallet 208,
On the other hand, the operation of the suction hole 804 and the like is stopped, and the outer bag B is supported by the bag receiving plate 601. Moreover, by this time, the suction conveyance mechanism 304 has returned to the top of the outer bag supply section 301.

Next, the bag receiving plate 801 is made with the bottom plate 602 vertical.

To support the bottom of an outer bag B filled with small bags. Thereafter, as the support portion 615 of the bag receiving plate 801 moves together with the arm 814 connected to the bottom thereof, the carrying-out conveyor 80 moves from the position where the outer bag B is opened.
8 along the shaft body 8113 provided in the Y-axis direction. The one-bag receiving plate 801 has a support portion 815.
However, by rotating around the shaft body BIB, it is in an inclined state with its bottom side facing downward.

Note that the above movement and tilting operations may be performed in reverse order.

In this state, the upper regulating plate 613 and the side regulating plate 612
is pressed and driven by an air cylinder (not shown) based on a command from the control unit 800, contacts the side surface Bs of the opening of the outer bag, and presses the inner pouch P from both sides of the opening of the outer bag.

Moreover, the above-mentioned suppression plate 809.

By operating the air cylinder 607 and the rod 60B based on a command from the control unit 900, the air cylinder 607 and the rod 60B are inserted into the opening of the outer bag and directly press the pouch group P. At this time, the suppressing plate 809 blows out an air stream from the plurality of nozzles 1311 of the air blowing section 610 so that the pressing plate 608 pushes the outer bag opening outward to prevent contact. . Thereby, the suppression plate 603 can be inserted smoothly.

In this way, the pouch P inside the outer bag B is pressed to collapse the internal gap and shape the outer bag.

Next, the side regulating plate 8 regulating the side surface of the opening of the outer bag B
12. That is, the folding claw 703 attached to the side folding plate fixing plate 702 is bent by the operation of the air cylinder 711, and the side part of the opening of the outer bag is folded inward. 0 When the bending is completed, the side folding plate 701 evacuate.

After that, the upper regulating plate 813 regulating the upper surface of the opening of the outer bag B, that is, the folding claw 705 attached to the fixed plate 706 of the upper folding plate 704 is bent by the operation of the air cylinder 717, and the outer bag B is folded. Fold the top of the opening inward. Then, when the lower folding plate 707 is rotated to bend the outer bag opening protrusion Bf inward,
