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 alignment packaging method and apparatus for automatically packaging the outer bag by sealing the opening thereof.

[Prior Art] The packaging of granules, such as rice, is carried out in 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 desirable 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.

In this case, the larger the measurement unit, the easier the handling during transportation. That is, when loading and unloading onto a truck or the like, 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.

It allows for stable loading and there is little risk of cargo collapsing.

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 loading and unloading onto a truck, etc., the handling unit is small, so the number of bags handled increases, requiring a long time to handle, and since each bag is small, it is not easy to stack them. However, the loading may be 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. Automatic packaging machines of this type have already been put into practical use for packaging 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 suctions and holds the sachets one by one using a vacuum suction cup or the like, transports them onto a stacking pallet, and places them at a predetermined position. In order to measure and allocate
This method requires a complex and sophisticated transport mechanism such as a robot arm that can move freely, making the device expensive, and if control software for the device is included, the entire system becomes very expensive.

In addition, when powders such as salt are packed in bags and compressed, they tend to solidify to some extent, so when stacking, inserting into outer bags, or sealing the opening of outer bags, it is difficult to Since it does not lose its shape, it can be handled without any rumors that special care is required. On the other hand, grains such as rice do not exhibit such properties and cannot maintain a fixed shape. When sealing the opening of the outer bag, the shape of the pouch may collapse, resulting in the interruption of these operations. Therefore, even if the packaging machine is an automatic packaging machine, it is necessary for the operator to constantly monitor the work status, which is inconvenient.

The present invention has been made in order to solve the above-mentioned problems, and is capable of suction-holding a plurality of small bags together using a vacuum suction cup or the like, transporting them onto a stacking pallet, dispensing them at predetermined positions, and stacking them. , stacking can be done using a simple conveyance mechanism, and the control of loading is also simple, making the equipment inexpensive, and making stacking and loading easier.
Taking into consideration the properties of the granules that can cause the shape of the pouch to collapse when inserting it into the outer bag or sealing the opening of the outer bag, packaging can be carried out smoothly without interrupting each of these operations, and the operator can An object of the present invention is to provide an automatic aligning and packaging method and device that eliminates the need for workers to constantly monitor work conditions and enables complete automation.

[Means for Solving the Problems] The above-mentioned means for solving the problems of the first invention of the present application is to arrange and store a large number of small bags filled with contents and conveyed and supplied in sequence in an outer bag, and to In the automatic alignment packaging method, which seals the opening of the outer bag and automatically wraps the bag, the small bags that are sequentially transported and supplied are lined up in groups and placed on the stacking pallet in this lined state. Then, arrange multiple sets in alignment units on the arrangement pallet.

On the other hand, empty outer bags are taken out one by one from the stacked outer bag supply unit, and the main surfaces of the outer bags are pulled while being suctioned from both outside sides, and an air stream is blown onto the open end of the bag to open it.

A guide plate is inserted into the opened outer bag to smoothly insert the stacked groups of small bags into the outer bag.

The group of small bags arranged above is pressed down and inserted into the outer bag along the guide board.

The pouch inserted into the outer bag is pressed and shaped from the outside and the opening of the outer bag, and then the opening of the outer bag is folded in and the glued part, which has been previously coated with glue, is inserted into the other bag. After temporarily sealing by pressing the
It is characterized by applying strong pressure to the glued portion to firmly seal the opening of the outer bag.

Furthermore, the m2 invention of the present application is an apparatus used for carrying out the automatic alignment packaging method of the first invention, and the means for solving the problem is as follows:
A large number of small bags are filled with contents and transported and supplied sequentially.
In an automatic sorting and packaging device that arranges items on a stacking pallet, stores them in outer bags, seals the openings of the outer bags, and automatically wraps the bags, it is installed at the discharge part of the conveyance means and sequentially conveys the items. Aligning means for arranging the supplied pouches in close contact with each other for each unit to be arranged; and arranging means for placing the plurality of arranged pouches on the above-mentioned arranging pallet in an aligned state. With means.

Exterior bag removal means for taking out empty exterior bags one by one from a multi-layered exterior bag supply unit; A bag opening means for opening the bags, a guide plate whose one end is located on the stacking pallet and which is inserted into the outer bag with the other end open, and which smoothly inserts the stacked groups of small bags into the outer bag, and the above-mentioned arrangement. a pouch inserting means having a suppression mechanism that presses the stacked pouch group and inserts it into the outer bag along a guide plate; A shaping mechanism that presses the outer bag opening to shape it; a folding mechanism that folds the outer bag opening by folding its four circumferences inward in accordance with the folding order; and a sealing mechanism that has a first pressing part that temporarily seals the outer bag and a second suppressing part that presses the glued part to firmly secure the opening of the outer bag and seal the opening of the outer bag. It is characterized by being composed of:

[Function] According to the present invention, the small bags that are sequentially conveyed and supplied are, for example, stopped in a predetermined area, and the subsequent small bags are brought into contact with this, and further.

By bringing subsequent pouches into contact with these in the same manner, they are aligned in the - row. Multiple sachets arranged in a row,
The bags are held by a plurality of holding outlets provided corresponding to each bag, and transferred onto a stacking pallet in an aligned state. Therefore, the pouch can be moved by simple interlocking trajectories such as parallel movement and turning. Therefore, a robot arm or the like with complicated structure and control is not required.

In addition, since the multiple pouches are placed in a line and are transferred onto the stacking pallet while they are lined up, there is no need for stacking them, and since the pouches are lined up, the positioning of each bag is easy. It is not necessary and the arrangement becomes easy.

On the other hand, empty outer bags are taken out one by one from the stacked outer bag supply unit and are opened by inflating the inner space by suctioning the main surfaces from both outsides by the bag opening means. At this time, an air stream is blown onto the opening end of the bag to prevent the glue applied to the opening of the outer bag from coming into contact with other parts. In the case of granules whose shape easily collapses, if the opening of the outer bag is small, part of the bag will often come into contact with a part of the opening, causing the shape to collapse and becoming difficult to insert. Since the opening is provided as described above, insertion of the stacked groups of small bags is not hindered.

Furthermore, 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 carefully stacked items to collapse. 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 groups of pouches,
It is smoothly inserted into the outer bag along the guide plate.

Unlike powder, granules can freely change the shape of the pouch, so when the granules are inserted into an outer bag, the arrangement may be disordered. Therefore, in the present invention, the pouch group is shaped by pressing from the outside of the outer bag and the opening.

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.

To simplify the process, the opening of the outer bag is sealed by applying glue to the glued part in advance and tuffing the glued part by pressing it against other parts. In the invention, the 1M fastening is not performed at once, but first, the glued part is pressed against other parts and lightly adhered to temporarily seal the part for positioning, and then the glued part is pressed hard to seal the outer bag. Firmly seals the opening.

The small bags P filled with rice are sequentially sent out at appropriate intervals from a supply section (not shown) and are conveyed 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 and arranged on the arrangement conveyor 104.

When the control unit 800 detects this state using the photoelectric detector 105 at the rear end of the alignment conveyor 104, it instructs the alignment conveyor 104k to send air pressure to the air cylinder 203 of the pouch holding mechanism 202 waiting. As a result, the rod 204 protrudes and lowers the suction cups 205 and 20G so that they come into contact with the pouches P on the alignment conveyor 104, respectively. Also, according to a command from the control unit 800, the suction S
fi 205 and 206 are connected to a vacuum device,
Suction the pouch P. Then, air pressure is sent to the air cylinder 203, the rod 204 retreats, and the suction cups 205 and 206 rise. The pouch holding mechanism 202 is moved along the moving rail 201 to a position above the stacking pallet 209 by a drive device (not shown). Here, the control unit 90
0, air pressure is sent to the air cylinder 203, the rod 204 protrudes, and the suction cups 205 and 20
6 is lowered and placed on the pouch P on the stacking pallet 209.

By repeating the above operations, the stacking pallet 209
Plural rows of pouches P are stacked on top. This stacking pallet 2
Small bag Pti on 09! In this embodiment, the product pattern is arranged in three layers: the bottom two rows, the middle one row, and the top two rows, as shown in FIG. The arrangement is performed in the numerical order shown in FIG. 5. This arrangement pattern is written in the sequence program of the control unit 900 in advance. Therefore, the layout 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,
An air cylinder (not shown) operates, and the regulation plate 207,
208 are rotated inwardly so that they are almost perpendicular to each other,
Control the pressure on the pouch group P from the side.

The gaps between the two sachets are crushed to form a dense stack.

On the other hand, in the outer bag supply section 301, the suction conveyance mechanism 304 is operated by the air cylinder 30B in response to a command from the control section 800.
The vacuum suction part 305 is lowered by the operation of the a
It is brought into contact with the main surface Ba of the outer bag B placed thereon, and further brought into close contact by vacuum suction using a vacuum device (not shown). After this, the suction conveyance mechanism 304 moves to the air cylinder 308
When activated, it rises and pulls up the adsorbed outer bag B.

At this time, the next outer bag B, which is stacked below the outer bag, may stick to the outer bag mainly at the glued part and be pulled up to H.6 In this embodiment, in order to separate this bag, A separating knife 308 placed next to 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 312 blow out 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 mechanism 304 moves along the moving rail 302 to the pouch insertion position while adsorbing the pulled-up outer bag B, and is lowered by the operation of the air cylinder 30B to place the lower surface Bb of the outer bag opening onto the suction cup 401. bring it into contact. about,
When the suction hole 402 of the suction l11401 is operated according to a command from the control unit 900 and the lower surface Bb of the outer bag is suctioned,
The suction conveyance mechanism 304 moves upward while adsorbing the outer bag-like surface Ba, and separates 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 B is prevented from coming into contact with each other or other parts, making opening easier. Also, if hot air is ejected from this air nozzle 403,
The glue applied to the opening of the outer bag B can be softened to facilitate and ensure subsequent gluing.

Next, in response to a command from the control unit 900, an air cylinder (not shown) is operated, and the guide g1501 moves toward 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, an air nozzle 617 is arranged below the outer bag to eject the air flow upward, as shown in FIG. It may also be designed to prevent sagging at the rear.

In this state, a bag receiving plate 801 is arranged on the lower side of the outer bag, and the outer bag B has a suction hole 8 provided in the bag receiving plate 601.
It is fixed by suction by 04. In addition, at this time, the bag receiving plate B0
The bottom plate 602 of No. 1 is in an open state.

Subsequently, the air cylinder 505 of the pressing mechanism 502 is activated, and the pressing plate 503 is brought into contact with one end side of the stacked small bag group P to press the small bag group P and close the open outer bag. Move it towards B.

Each pouch P is sequentially moved from the stacking pallet 208 onto the guide 1501 and inserted into the outer bag along the guide plate 501. At this time, since the upper surface of the guide plate 501 has a smooth surface, the friction with the bag group P is reduced, and no catching occurs due to friction, so that the stacking does not collapse due to this.

In this way, when the small bag group P is inserted into the outer bag B, the guide llll501 retreats to the lower surface of the stacking pallet 209, while the operation of the suction holes 804 etc. is stopped, and the outer bag B It is supported by a receiving plate 601. Also, by this time,
The suction conveyance mechanism 304 has returned to the top of the outer bag supply section 301.

Next, the one-bag receiving plate 601 makes the bottom plate 602 vertical so that it can support the bottom of the outer bag B filled with small bags. Thereafter, as the support portion 615 of the bag receiving plate 601 moves together with the arm 614 connected to the bottom side of the bag receiving plate 601,
It moves along the shaft body 81G provided in the Y-axis direction from the position where the outer bag B is set to be opened to the entry side position of the carry-out conveyor 808. The bag receiving plate 601 is in an inclined state with its bottom side facing downward as the supporting portion 615 rotates about the shaft body 81B.

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 900, comes into contact with the side surface Bs of the opening of the outer bag, and presses the pouch P inside from both sides of the opening of the outer bag.

Further, the suppression plate 608 is inserted into the opening of the outer bag by the operation of the air cylinder 607 and the rod 608 based on a command from the control unit 900, and directly presses the small bag group P. At this time, the suppressing plate 609 ejects air flow from the plurality of nozzles 611 of the air ejecting section 810, and the suppressing plate 609
9 pushes the outer bag opening outward to prevent contact. Thereby, the press plate 609 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, a side regulating plate 6 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 B13 regulating the upper surface of the opening of the outer bag B, that is, the folding claw 705 attached to the fixed plate 70B 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,
The edge folding plate 704 and the lower folding plate 707 are respectively retracted.

Next, the first suppressing part 801 of the sealing mechanism
2, and by its pressing plate 804.

Lightly press the folded end of the outer bag to temporarily seal it.

Thereafter, the outer bag B falls due to the rotation of the one-bag receiving plate [1] and is conveyed by the carry-out conveyor 808. When the control unit 900 detects that the outer bag B has reached a predetermined position on the carry-out conveyor 808 using a proximity sensor (not shown), the control unit 900 rotates the swing arm 807 of the second suppression unit 805 and moves the impact plate 80
At step 8, the edge of the outer bag is hit hard. As a result, the glued portion is completely adhered and firmly sealed.

[Effects of the Invention] As explained above, the present invention is capable of sucking and holding a plurality of small bags together using a vacuum suction cup or the like, transporting them onto a stacking pallet, dispensing them at predetermined positions, and stacking them. A simple transport mechanism allows for stacking, and the equipment is also easy to control.
The equipment is cheaper.

In addition, when stacking, inserting into the outer bag, and sealing the opening of the outer bag, we take into account the properties of granules that can cause the shape of the pouch to collapse, so that each of these operations can be carried out smoothly without interruption. It has the effect of eliminating the need for workers to constantly monitor the work status and allowing for complete automation.
