Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic case filling device for weighed and packaged and soft-packaged products.

Conventionally, products produced in factories are weighed and packaged in predetermined units when being distributed to consumers, and the predetermined number of products are packed into containers such as cardboard cases and placed on distribution channels.

This container packaging ensures that the product has the same shape, for example, cosmetics, medicines, etc. are packed in one bottle and a plastic container.
Or, if this is further packaged in a box-like carton container, it may be packaged and then stacked in a predetermined number and then automatically packed into cardboard cases using a machine called a wrap-round caser. Products packaged using paper, plastic film, or a packaging material Y [laminated with these materials] are widely used because they are easy to package and have low packaging costs. As the name suggests, packaging materials are soft and flexible against external forces, making it difficult to maintain the same shape.
In addition, the packaging material is slippery, making it extremely difficult to assemble, and the contents are often used for relatively inexpensive products such as pastries and snack foods, so packing them into cardboard cases is difficult. It has been done mainly by human power.

Therefore, this invention was developed for paper, plasti, and film.

The present invention provides an "automatic case filling device for weighed and soft-packed products" for the purpose of automatically packing soft-packaged products by laminating them into cardboard cases.

Hereinafter, one embodiment of the present invention will be explained with reference to the drawings, focusing on a pillow-type package, which is the most common type of flexible packaging.

The automatic case packing device of the present invention consists of: 0 automatic feeding and forming device for corrugated cardboard cases @ packaging product feeding device θ packaging product inspection and alignment device O packaging product boxing device, and each of the above devices is controlled by a control section (not shown). It controls its operation.

First, the automatic feeding and forming device for corrugated cases shown in (■) places a large number of corrugated cases (hereinafter simply referred to as cases) (A) almost vertically in a case magazine (1), and the positions are regulated using guide plates (2) on both sides. and the cardboard case at the front (N
7. Avoid falling forward. The rear part of the case magazine (1) is pushed forward by a case pusher (4) (not shown, simply indicated by an arrow). Then, a molded arm (6) is pivotally attached to the case magazine with a shaft (5) located on the opposite side of the front row 7 hooks (3) of the case magazine (1) as a fulcrum, and a vacuum is attached to the tip of each arm. (7) are provided.

To explain how this device works, the rear part of the case (A) (formed into a square cylinder, the front part is based on the direction of travel),
(referred to as the rear part and its left and right sides are referred to as side surfaces), and move the molding arm (6) 90 degrees counterclockwise when viewed from the top.

As a result, the case (N) becomes a rectangular tube shape and is located in the case molding part (W) away from the hook (3), and then the case pusher (8) (not shown, indicated by an arrow) is used to push the case into the molded part (W). (W) sends it to the case special equipment section (X), and if the package case filling section (Y) is empty, it is further moved back and forth to that position.

When the case (4) is supplied to the packaged product case filling section (Y'), the loading table (9) is moved from the bottom to a predetermined position (one level of the packaged product from the ruled line (,) inserted to form the upper lid surface). At the same time, the flap Q0 at the rear lower part of the case becomes horizontal to the inside of the case (A) until the flap Q0 at the rear lower part 7 is bent (not shown in the figure). Fold it.

Next, to explain the configuration of @'s packaging product feeding device, the product is weighed by a predetermined amount using a measuring device (not shown), and the lower part of the cylindrical packaging film 0υ formed by the packaging machine (B) is sealed. Then, the upper part of the film is sealed and at the same time it is pressed to a predetermined size to form a packaged product (0). A first arm support shaft (6) is provided horizontally at approximately the same height as the packaged product (0), and the first suction arm (2) is rotatably attached to the arm support shaft. , the tip of the suction arm α→ is connected to the first suction and de (141
is provided, and the center part of the packaged product (0) to be wrapped by the packaging machine (B) is held by suction and separated, and at the same time, the arm support shaft Q frame is used as a fulcrum and rotated 18080 degrees clockwise. Stop moving. and a second arm support shaft (6) that is pivoted to a second arm support shaft (G) located at a location apart from the arm support shaft (6).
The suction arm αQ suctions and holds the packaged product (0) that has stopped rotating by 18,080 degrees, and the first suction head O
The lever moves away, and the first suction arm OJ returns to its old position and stands by in preparation for the next operation.

To the second suction, the packaged product (0) held in the do-Q is rotated 90 degrees counterclockwise with the second arm support shaft OFJ as the fulcrum, and the packaged product (0) is inspected (seal check). Conveyor) After being placed on the conveyor, it returns to its previous position.

Next, the inspection and alignment equipment for the θ packaged products (0) consists of a seal check conveyor 0, an alignment table OI, a seal check, and a removal device. (18Q) and a center conveyor (18b) located at a slightly lower position in the center.
The center conveyor (18b) is formed to have a length shorter than the rear end of the side conveyors (18a) and (184) by approximately one package, as shown in the plan view in Fig. 4. and the second one adsorbed the packaged product (0).
Suction arm 1. IQ rotates 90 degrees counterclockwise, passes between the side conveyors (18 & The packaged product (0) is lowered together with the side conveyor (18a) (1
Place it on 8a3 and return to the old position to prepare for the next operation.

Packaged products (0) transferred to the seal check conveyor (G)
) When the transfer operation is completed, the seal check conveyor (to) is driven forward in the direction of the alignment table θ having the length of one package, and the seal check is installed on the top of the conveyor.

feed into the lower part of the filter unit (E).

Seal check equipment M (E) is pad holder (20a)
One of several sets (5 sets in this example) of pneumatic rollers (20b) formed to fit over the top surface of the packaged goods held at the seal checker, and an alignment stand 0 on the conveyor (top). During the transition, place the packaged product (0) on top of it and hold it down to the extent that it does not damage the contents of the packaged product. Pressure detection sensor (20t+) detects changes in internal pressure (
20c), and then sent to the alignment table 0.

The packaged products (0) sent to the sorting table On are subjected to a seal check in the sealing section (z), and if a defective product is detected as a result of the seal check, a removing device (not shown) packs only good products into cases.

In this example, four bags of packaged products are placed in one layer on a flat surface, and an alignment table (
When the products are sent to II (defective products are removed at this point), they are first moved 90 degrees horizontally by a cross-feeding device (not shown), then the next package is sent in. Finally, the package marked with ■ is transferred. The boxing equipment is mainly a case packing machine and a loading table (9)
It consists of a case filling machine @I) Ha, 2 pieces (7,)
chi)-0,) (21a), (214 ni fitting t.

It consists of a slider (2xb) that can slide back and forth, (ztb5), and a third suction arm (2 melon (23')) with a third suction arm (22) (22) attached to its tip. .

The third suction arm (2 turtle (23') is the slider 31υt
(In this case, it is configured so that it can swing around the attachment part to the 2i b5 as a fulcrum, and is configured as an integral unit, and is positioned at a predetermined position on the loading table (9) by a separately provided drive device and control device (not shown in the figure). ) on this case (the width direction of N is
Since this is to match the packaged items (0) lined up on the sorting table oI, two locations for the case (1/4 and 374 points of the length of the case from the front) are determined in the direction of travel. The center part of the packaged products (0) lined up on the alignment table 0I is moved to the third suction
After adsorbing the case with the case (221 (22')) and raising it slightly, we set a trajectory in advance to reciprocate between two points on the loading table (9) without touching the four sides of the outer periphery of the case. The system repeats the process of moving, stopping suction, and then transferring to a fixed position.

By performing this operation twice, the case (A) is stuffed by one level in the height direction, and each time, the loading tape A/(9
) is lowered by one step until reaching the predetermined lowest step, and the packing of the predetermined number of cases is completed by transferring the packaged products to the uppermost step.

The position of the lowermost loading table (9) is directly above the folded back 7 OO in the feeding direction, and as the case packing progresses, when this position is reached, the loading table (9)
) is moved to the lower part of the front half (9a), and the packaged product (0) is loaded on the loading table (9) and the packaged product (0) is moved onto the flap (10). It will be posted.

This is done by dividing the loading table (9) into two parts in advance, and dividing the latter half (9) into two parts.
This is done by making b) a structure that can be slid into the lower part of the front half (9a) and taken out.

On the other hand, as soon as the case filling operation of the last packaged product ((1) is completed, the loading table (9) is
) is further lowered slightly and stopped, and at the same time feeds the next cardboard case which has been formed into a rectangular tube shape and is waiting, into the packaged case active part (Y), and the fully packed cardboard case (A) is moved to the lower both sides 7, Push it out into the folding device (c).

At this time, as the pushing operation progresses, the packaged goods loaded on the front half (9a) of the loading table (9) are moved to the front and rear flap receiving bars (provided as front and rear flap receiving bars), and the lower front section (10) is moved. The packaged items are sequentially transferred onto the front half (9a) of the loading table (9) while being turned inside, and then proceed to the rear lower part 7, pu (1 east front and back 7, pu), and are supported by the receiving bar (c). When the extrusion process is finished and stopped, the lower part 7 on both sides, which is divided into two parts (front and back), waits vertically until then.
0a), (on the 4-lar conveyor for folding 104),
− is horizontal, and the flaps on both sides of the bottom.

Fold (toa), (to4 inward and hold.

After folding the flap, the rear half of the roller conveyor dryer returns vertically again and is held only by the front half, and the next step is to send out the cardboard case, which seals the cardboard case.
That is, the upper and lower both side flaps (xob), (10b5 > (
10a)>(10m5 of tape is pasted on). When finished, the first half of the four-wheeler conveyor (E) is returned to its old position and stands by in preparation for the next operation.

These operations are performed by the packaging machine (B), and the entire system is controlled according to the timing at which the product is packaged.The number of times the packaging machine (B) wraps depends on the product.
Although it varies depending on the situation, if it is done about 60 times per minute, the interval is around 1 second, which is a short time, but if it is a normal product at that time, the first suction arm (goods) is removed from the packaging machine (0). Receives the packaged product (0) by the second suction arm (10), transfers it to the seal check conveyor (1 frame) by the second suction arm (10),
It is possible to arrange the sheets on the sorting table Q1 from the seal check conveyor tta, and to fill the cardboard cases with the third suction arm).

However, it is difficult to perform sufficient sealing and sealing, so by providing a sealing conveyor, it takes time to seal and seal at least 2 to 3 bags more completely.

In addition, sending out the multi-pole case after case packing has been completed,
It is thought that it would be even more difficult to carry out the case exchange operation to send the next stacked pole case to the fixed position within this time, so the third suction arm
G) Case packing operation - Several bags are simultaneously carried out once, and one stage of the case packing pattern is shown in this example.
The operation can be adjusted by matching the number and arrangement of υ on the alignment table (alignment method in II, third suction arm c13m and vacuum head) so that the alignment is carried out twice per /2 or once per stage. It is possible to consider a method of packing cardboard boxes by leaving intervals and relaxing the rate-limiting of this series of operations, and if there is still insufficient time, the packaged items (0) may be packed in contact with the sorting table rs, for example, perpendicular to the traveling direction of the packaged item (0). A conveyor-like stock section is provided that moves outward each time (0) is transferred to the sorting table Ql from the seal check section (Z), and the case exchange operation is completed and the next cardboard packing is started. Until then, the packaged products that have been produced, sealed, and removed are stored and removed, and once the replacement is completed, they are packed in cardboard cases together with the packaged products that are being produced, removed, and sent to the sorting table DI until the next case change. By doing so, it may be configured such that even if it takes some time to replace the cases, the work can be performed without reducing the performance of the packaging machine.

Next, when using this automatic case filling device, the bag dimensions, content weight, etc. of the packaged product have already been determined, and the number of bags to be packed into the cardboard case is also determined based on this. Therefore, a cardboard case used as a container is processed into a predetermined size and design, printed, and then delivered to a factory in a folded state so as not to be bulky for delivery.

In this invention, one packaged product feeding device is shown, but two packaging devices may be installed in parallel (therefore, two packaging devices fi (B) are also arranged in parallel). Although one alignment device is shown, a plurality of alignment devices may be provided in parallel.

As explained in detail above, the present invention uses a feeding device to automatically process pillow-type packaging products that were conventionally wrapped with flexible packaging film and manually packed into cardboard cases, and also reverses the vertical position of the packaging products. Because the contents packed by the packaging machine are unevenly distributed at the bottom of the bag, even if the top of the bag is empty and becomes almost a spindle cedar, the shape can be automatically averaged, and the contents can be evened out when packed in sealed boxes or boxes. It is extremely convenient and does not break anything.

In addition, in the inspection of packaged products (seal check, ri), conventionally when packing by hand, it was possible to determine whether the bag was good or bad by the feel of the hand. However, this inspection device uses a seal check, a conveyor, and multiple seal check devices to perform seal checks while moving on the conveyor, allowing seal checks to be carried out effectively and quickly. .

You can do it.

In the packaged product boxing device, the third suction arm and the loading table that descend sequentially work together to keep the packaged product held at the tip of the third suction arm at a certain height in the case. The shortest course is designed to avoid contact with the upper end of the case, and the movement is also configured to move on a vertical plane, which simplifies the mechanism and allows processing to be completed within the packaging cycle.

In addition, since the automatic cardboard case supply/forming device supplies folded cases, it does not take up much space, and a large number of cases can be supplied at one time, so that there is no need to worry too much about replenishment.

As described above, in this invention, each device automatically operates without the need for human intervention, and the boxes are packed while thoroughly checking all of the packaged products, resulting in much higher reliability and labor-saving than if done manually. The effect is sufficient and extremely beneficial.
