Abstract

PURPOSE:To prevent a trouble of dropping down through a gap between tables by a method wherein a flat pack is placed on a magnet which is fixed in a recessed part formed at an upper end of two slit-embedded pieces which are one and two before each pusher of a conveyor, magnetically attracted floatingly from the tables on the both sides and fed into an opening of a bag maker. CONSTITUTION:A slit-embedded piece 10 between pushers 9 of a conveyor C is made to have a little smaller size than a table 7. A recessed part is formed at an upper end of two of the slit-embedded pieces 10 which are one and two before each of the pushers 9, in which a magnet 11 is fixed, and a flat pack P is placed on the magnet 11. The flat pack P is magnetically attracted from the tables 7 on the both sides, a tray T is put on the pack P, and a goods is housed in the tray T and all of them are transferred. By this, the flat pack P can be prevented from dropping down through a gap S' between a rear end triangle part 7a of the table 7 and a front end triangle part 1a of a bottom plate part of a bag maker 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a horizontal bag-making filling and packaging method for packaging a flat pack of a small oxygen absorber under a tray or a product.

[0002]

2. Description of the Related Art Conventionally, in a horizontal bag-filling and packaging method, when a small flat pack, which is a hygroscopic agent, is to be packed under a tray, the small flat pack is pushed by a pusher and conveyed to a table. The small flat pack that may be displaced to one side due to friction is displaced to the one side, and when the small flat pack is transferred from the rear triangular portion of the table to the front triangular portion of the bottom plate of the bag making machine, the pack tip is manufactured. There is a problem that it gets caught in the edge of the front triangular part of the bottom plate part of the bag container and falls from the gap between the two.Therefore, in order to prevent such problems, place a small flat pack on the tray in the horizontal bag filling packing method When packaging with other products, the small flat pack is often placed on a tray and then the product is placed and packaged.

[0003]

As described above, the applicant of the present invention ventilates a deoxidizer composed of reduced iron powder for removing residual oxygen in the bag by an oxidizing action in the degassing packaging or the gas displacement packaging. A small flat pack of about 3 cm square, which was heat-sealed in four directions with a flexible film, was placed under the tray, and an attempt was made to wrap the flat pack. I couldn't eliminate the trouble of falling from the gap between.

According to the present invention, a flat pack of a small oxygen scavenger is placed under the tray on the table of the product feeding conveyor, or when there is no tray, it is placed under the product and conveyed by the pusher to make a bag making machine. Even if it is sent into the package and packed, there is no problem that the flat pack falls from the gap between the rear triangular part of the table and the triangular part of the front plate of the bottom plate of the bag making machine.
It is an object of the present invention to provide a horizontal bag-filling and packaging method in which a flat pack of a small oxygen absorber is placed under a tray or a product for packaging.

The flat pack P of the oxygen scavenger made of reduced iron powder is placed on top of the table, and the flat pack P of the oxygen scavenger is magnetically attracted so that the flat pack P of the oxygen scavenger floats from the tables 7 and 7 on both sides, and the bag making machine 1 is opened. Provided is a horizontal bag-filling and packaging method for packaging a flat pack of a small oxygen scavenger placed under a tray or a product, which is characterized in that it is fed into the bag.

[0006]

EXAMPLE A horizontal bag-making filling and packaging method for packaging a flat pack of a small oxygen scavenger under a tray or a product according to an embodiment of the present invention, as shown in FIG. Similar to the vertical bag-making filling and packaging method, the packaging film fed from the material roll R is hung on the bag-making machine 1 to be bent into a tubular shape, and the edges of both sides of the packaging film F below the bag-making machine 1 are formed. f1, f
One of them is put together and sandwiched by a pair of pinch rolls 6 to feed the film, and the heater roll 3 performs center sealing to form a packaging cylinder H, and an endless chain 8 below the table 7 of the product feeding conveyor C.
The tray T is placed in front of the pusher 9 which is attached at a constant interval and moves up and moves at a constant interval from the slit S between the tables 7 of the product feeding conveyor C by the chain drive, and the product W is placed thereon. In addition, the slit space is filled with a plurality of slit filling pieces 10, 10, 10, ... Which are arranged in a line from the endless chain 8 so that the product does not fall into the slit space between the pushers 9, 9. Then, the tray T on which the product W is placed is pressed and conveyed, and is fed into the packaging cylinder H from the opening of the bag making machine 1 at regular intervals, and the end seals, cutters 4, 4
The end seal / cut is made between the products of the packaging cylinder H.
