Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an automatic arranging device for automatically arranging a large number of sachets filled with contents and supplied sequentially.

[Prior Art] Packaging of granules, for example rice, is carried out in a predetermined amount, for example 10,
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.

In this case, the larger the measurement unit, the easier the handling during transportation. In other words, when loading and unloading onto trucks, etc., the handling units are large, so the number of items to be handled is reduced and the work can be done in a short time.Also, since each bag is large, it is easy to stack, and it is also stable. It can be stacked in multiple locations, 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. Moreover, the stacking is unstable and there is a risk of the cargo collapsing.

Therefore, it has been considered to solve the above problem by storing a plurality of small bags together in a large outer bag so that the outer bag can be used as one bag during transportation. In this case, it is necessary to insert the plurality of small bags into the outer bag properly and to be able to insert them smoothly without the small bags coming into contact with the outer bag opening or the like during insertion.

For this reason, in the past, the small bags being transported and supplied were placed one by one on a stacking plate according to a predetermined layout pattern, a plurality of bags were stacked, and the bags were inserted into the outer bag in the stacked state (
(See Japanese Patent Application Laid-Open No. 130-217928).

[Problems to be Solved by the Invention] However, in the conventional stacking proposed above, the small bags are sucked and held one by one using a vacuum suction cup, etc., and then transported onto the stacking plate and placed at a predetermined position. The disadvantage is that the equipment is expensive because it requires a complex and sophisticated transport mechanism such as a robot arm that can move freely, and when the equipment control software is included, the entire system becomes extremely expensive. The present invention was made in order to solve the above problems, and it is possible to carry a plurality of small bags together onto a stacking plate and stack them at a predetermined position using a simple conveyance mechanism, and also to control the device. It is an object of the present invention to provide an automatic arrangement device for stacking that can be simplified.

[Means for Solving the Problems] The present invention provides an automatic arrangement device for automatically arranging a large number of pouches that are filled with contents and supplied sequentially. with a conveyor.

a sorting conveyor disposed on the exit side of the conveyor and arranging the pouches received from the conveyor in units of a plurality; and a sorting conveyor for starting/starting the sorting conveyor according to the outlet side of the sorting conveyor and the position of the pouches on the sorting conveyor. The present invention is characterized in that it is configured to include a control device that controls stopping.

[Function] In the present invention, the pouches that are sequentially conveyed and supplied are, for example, stopped in a predetermined area, and the following pouches are brought into contact with the pouches, and in the same manner, the pouches that follow the pouches are brought into contact with these pouches. By bringing them into contact with each other, a plurality of pieces are aligned in a line.

This alignment is performed on an alignment conveyor. When the control device detects that a pouch approaches the exit side of the conveyor, it starts the alignment conveyor, moves the belt by the length of the pouch, receives the pouch, and stops the pouch when the zero-order pouch approaches. The alignment conveyor waits in this state until the

When the control device detects that the next pouch approaches the exit side of the conveyor, it moves the alignment conveyor in the same manner as described above and receives the pouch onto the alignment conveyor. As a result, the first pouch and the following pouch come into contact with each other on the alignment conveyor.
arranged in rows.

In this way, in order to align a plurality of sachets, in the present invention, the entire bag can be moved onto the arranging pallet while remaining aligned. No control is required, therefore,
The transport mechanism for stacking can be simplified, and the control of the device can also be simplified.

The first pressing part 801 is configured to lightly press the folded and sealed end after the opening of the outer bag is folded. On the other hand, the second
The pressing part 805 falls due to the rotation of the bag receiving plate 801, and
The outer bag B being conveyed by the carry-out conveyor 808 is strongly pressed at a suitable position on the carry-out conveyor 808.

The control section 900 shown in the above configuration feature (i) consists of a feedback control section and a sequence control section, and the former mainly controls the operation of the alignment means 100,
The latter is configured to mainly control 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 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 800, 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 to lower the suction cups 205 and 208, and bring them into contact with 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 suck the pouch P. Then, air pressure is sent to the air cylinder 203, and the rod 204 is moved back to move the suction cups 205 and 20B.
rises. The pouch holding mechanism 202 moves the stacking pallet 20 along the moving rail 201 by a drive device (not shown).
Move to the position above 9. Here, air pressure is sent to the air cylinder 203 according to a command from the control unit 900, and the rod 204 protrudes to attract l! 205 and 20B are lowered and placed on the pouch P on the stacking pallet 208.

By repeating the above operations, the stacking pallet 209
Plural rows of pouches P are stacked on top. This stacking pallet 2
In this example, the pouch P arrangement pattern on 03 is the second
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 arranged on the arrangement 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,
The pouch group P is compressed and regulated from the side to collapse the gaps between the pouches P and achieve high-density stacking.

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 900.
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 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 stacked below the outer bag may adhere to the outer bag mainly at the glued part and be pulled up together. A separating knife 308 disposed beside the outer bag supply section 301 rotates (approximately 90 degrees), and the knife 30B 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 descends by the operation of the air cylinder 30B, and hits the lower surface Bb of the outer bag opening with the suction m401. Let them come into contact with you. about,
According to a command from the control unit 900, the suction hole 4 of the suction cup 401 is opened.
02 is activated and sucks the lower surface Bb of the outer bag, the suction conveyance mechanism 304 moves up while adsorbing the outer bag-like surface Ba and separates the north lower surface Ba and Bb of the outer bag.

At this time, air is ejected from the air nozzle 403 to prevent the glue applied to the opening of the outer bag B from coming into contact with each other or other parts, thereby facilitating opening. 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 panel 501 moves toward the stacking pallet 20.
3 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 601 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 801.
It is fixed by suction by 04. At this time, the bag receiving plate [1
The bottom plate 602 of No. 01 is in an open state.

Subsequently, the air cylinder 505 of the suppression mechanism 502 is activated, and the press 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 open outer bag. Move it towards B.

Each pouch P is sequentially moved from the stacking pallet 209 onto the guide fi 501 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 plate 501 is retracted to the lower surface of the stacking pallet 209,
On the other hand, the operation of the suction hole 604 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 601 makes the bottom plate 602 vertical so that it can support the bottom of the outer bag B filled with sachets. Thereafter, as the support portion 815 of the bag receiving plate 801 moves together with the arm 614 connected to the bottom side of the bag receiving plate 801,
It moves along the shaft body 131B 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. In the one-bag receiving plate 801, the support portion 615 is
By rotating around the shaft body 81B, 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 813 and the side regulating plate 812
is pressed and driven by an air cylinder (not shown) based on a command from the control unit 900, 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.

Further, the pressing plate [9 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 800, and directly presses the small bag group P. At this time, the press plate 809 ejects air flow from the plurality of nozzles 611 of the air jet section 610, and the press plate 609
The outer bag opening is pushed outward to prevent contact. Thereby, the press plate 809 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. When the bending is completed, the side folding plate 701 is retracted.

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 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 upper folding plate 704 and the lower folding plate 707 are each retracted.

Next, the first pressing part 801 of the sealing mechanism is pressed against the air cylinder 80.
2, and the pressing plate 804 lightly presses the folded end of the outer bag to temporarily seal it.

Thereafter, the outer bag B falls due to the rotation of the bag receiving plate 601 and is conveyed by the carry-out conveyor 808. Control unit 300
When the proximity sensor (not shown) detects that the outer bag B has reached a predetermined position on the carry-out conveyor 808, the second
The rotating arm 807 of the pressing part 805 is rotated, and the impact plate 8
At step 08, the edge of the outer bag is hit hard. As a result, the glued portions are completely adhered and firmly sealed.

[Effects of the Invention] As explained above, the present invention has the effect that a plurality of small bags can be collectively transported onto the arrangement plate and arranged at a predetermined position using a simple conveyance mechanism, and that the control of the device can also be simplified. be.
