Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a package used for stacking a predetermined number of polyethylene bags, a method for producing the same, and a mechanical device used for producing the package.

Conventionally, a predetermined number of bags made of polyethylene or the like were placed and sealed manually.

The present invention aims to automate this work, provide packaging suitable for automation, provide a method for producing the packaging, and provide a mechanical device suitable for producing the packaging.

The present invention will be described in detail based on the drawings.

1 is a main shaft placed in the main body, 2 is a U-shaped saucer, and 12 (lliI) are arranged radially around the main shaft 1, and the part corresponding to the right edge of the U-shape of saucer 2 is the main shaft. 1. Reference numeral 3 denotes an intermittent drive device, which is connected to the main shaft 1 via an arbitrary power transmission means such as a chain, and is configured to rotate the main shaft 1 intermittently by 30 degrees.

When the saucer is at position A and temporarily stopped, a strip-shaped film 5.5 having welded strips formed by heat seal welding 4 is stretched directly above the saucer 2. Rectangular bag products are fed one by one directly in front of the tray at position A, and stacked up to a predetermined number of bags, such as 10 or 20 bags.

The following device is arranged between the saucer at position A and the saucer at position B. On both sides there are rolls 9, 9 of band-shaped flexible synthetic resin films 5, 5, and the films extending from both sides are heat-sealed and welded as described above. Directly above this film 5.5, a sealer 10 and a seal receiver 11 are arranged which face each other and approach or separate from each other, and on the opposing surfaces of the sealer 10 and seal receiver 11 are silicone rubber 1, 2, 12. A heater wire 13 is disposed on the opposite surface of the sealer 10, and a Teflon layer 14 is covered. Branch pieces 15, 15 are provided on the seal nozzle SL-10 and the seal receiver 11, and the branch pieces 1
A rod 17 is slidably supported by a spring 16 arranged on the rod 5, and a side presser 18 is provided at the tip of the rod 17. When the cradle carrying the product rises to position B, it hooks the film 5 and rises to a position past the side presser 18, as shown in FIG. At this point, stop the saucer, bring the left and right sealers and seal receivers close together (Fig. 6) and make contact (Fig. 7), and energize the heater wire to heat-seal and weld the clamping part and cut the center of the seal part. do. After that, when the left and right sealers and seal receivers are separated, the state shown in FIG. 7 will be obtained. At this point, the state returns to the initial state shown in FIG.

When the saucer is rotated 30 degrees to position C, no processing is done.

When the saucer is rotated by 30 degrees to its original position, the center of the lower edge of the film is heat sealed by the heat sealing device 19 through the rectangular notch.

When the saucer is rotated 30 degrees to position E, the upper edge of the film is heat sealed by the heat sealing device 2.

When the saucer rotates 30 degrees and reaches position F, no processing is done.

When the tray is rotated 30 degrees to position G, the film bag located in the rectangular notch of the tray is placed on the rear conveyor 20. Thereafter, the tilting conveyor 21 falls down about the fulcrum 22 and comes into contact with the upper surface of the film bag, and the film bag is sandwiched between the rear conveyor 20 and the tilting conveyor 21 from above and below. Here, the rear conveyor and the tilting conveyor are driven, and the film bag is extracted from the tray and sent to the next process.

When the saucer is in the H, I, and J positions, nothing is processed. Therefore, according to the present invention, it is possible to automate packaging, which has conventionally been done manually.

That is, in the packaging of rectangular products according to the present invention, heat-sealed welding stripes are provided in the upper and lower directions on both the front and back sides of the film packaging surrounding the rectangular bag group, and the lower edge is provided with the film 5.5 in the center part on the front and back sides. The upper edge is completely welded, and configuring the film packaging in this way makes it very easy to automate.

In addition, in the method for packaging rectangular bag products according to the present invention, a group of synthetic resin bags 8 is placed on a saucer 2 having a rectangular notch 6, and a film 5 which is butt-welded from the left and right is placed on top of the group 8, and both edges of the film 5 are was bent downward and butt welded, and the films 5.5 on the front and back sides of the rectangular notch 6 were welded, and the films 5.5 on the front and back sides of the outer edge of the saucer 2 were welded, and then removed from the saucer 2. By doing so, it is possible to easily package rectangular bag products.

Furthermore, the packaging device for rectangular bag products according to the present invention has a plurality of U-shaped trays 2 radially attached to a main shaft 1 that is driven intermittently, and rectangular bag products are fed one by one onto the trays 2 to a predetermined number of sheets. The feeding device 7 and the rectangular notch 6 of the saucer 2 stack up to
A rear conveyor 8 that fits into the conveyor 8 is placed front and back across the main shaft 1, and rolls 9 of the belt-shaped soft synthetic resin film 5 are placed on both sides of the tray 2 which is continuous with the feeder 7, and the rolls 9 of the belt-shaped soft synthetic resin film 5 are moved forward and backward facing each other. A silicone rubber 12 is attached to the facing surfaces of the sealer 10 and the seal receiver 11, and a heater wire 13 is arranged on the outside of the silicone rubber 12 and Teflon 14 is placed on the opposite surface of the sealer 10, and the sealer 10 and the seal receiver are A branch piece 15 is attached on top of 11, and a spring 1 is attached to the branch piece 15.
6 to slidably support the rod 17, a side presser 18 is provided at the tip of the rod 17, a saucer in an upright position, a heat sealing device 19 along the bottom of the rectangular notch 6 of 2, and the Next to the upright position, a heat sealing device 23 is provided along the outer edge of the saucer 2, and the rectangular notch 6 of the saucer 2 in the rear horizontal position is installed.
It consists of a rear conveyor 20 that fits into the bag, and a tilting conveyor 21 that overlaps the rear conveyor 20 from above, and can manufacture rectangular bag products very efficiently.
