Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an empty bag take-out device for taking out one empty bag such as a plastic bag or a paper bag placed one on top of another in a container, which is used for a bagging device for vegetables and confectionery. It

2. Description of the Related Art As an empty bag take-out device, for example, an actual bag shovel 57.
In Japanese Patent Publication No. 9705, empty bags are taken out one by one with a suction cup that abuts and adsorbs on the left and right centers of the bags stacked in the container. Further, Japanese Utility Model Laid-Open No. 56-175309 discloses a structure in which the uppermost empty bag of the empty bags in the container is taken out one by one with an adhesive body adhered to the left and right centers thereof.

DISCLOSURE OF THE INVENTION It is difficult to remove one by one from empty bags stacked in a container due to generation of static electricity or the like. Therefore, in the past, measures such as preventing the generation of static electricity and pressing a part of the stacked empty bags to prevent the lower empty bag from being attached when taking out one sheet have been considered. It wasn't enough. It is an object of the present invention to take out empty bags one by one with a simple structure.

[Means for Solving the Problems] In an empty bag take-out device for adhering or adsorbing the uppermost bag of empty bags 2 stacked in a container 1 to take out one by one, an adhesive surface 3 or an adsorbing surface is provided at the tip. A plurality of drawer rods 4, 5, 6, 7 provided are juxtaposed and juxtaposed on the lateral frame 9 at the tip of the extraction arm 8. The drawer rods 5 and 6 are made to project larger than the outer rods 4 and 7. It was

[0005]

According to this construction, the tips of the plurality of drawer rods 4, 5, 6, 7 are the uppermost empty bags 2 in the container 1.
It comes in contact with and adheres or is adsorbed and pulled out.
Since the inner ones 5 and 6 of the drawer rods are longer than the outer ones 4 and 7, when they come into contact with and separate from the empty bag 2, the outside comes off earlier and then the inside comes apart, and the outside is flipped over to the empty bag. One of the two empty bags is pulled away from the other empty bag, the air passage between the first empty bag 2 and the other empty bag 2 is improved, and the separation is effectively performed. It will not happen that several empty bags 2 after the second empty bag 2 are taken out.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a vegetable bag packing apparatus using the empty bag take-out apparatus of the present invention will be described with reference to the drawings. The overall structure is a square box-shaped machine frame 10 with an opening 1 in the upper center.
1 is provided with a bag holding mechanism 12, and an empty bag 2 is provided inside the machine frame 10.
A bag take-out device 13 for taking out the empty bags 2 one by one from the bag container 1 in which the two are stacked is provided, a conveyor 14 is provided obliquely upward from the lower part in the machine frame 10, and a conveyor is provided from a chute 15 in the machine frame 10. A bag for storing vegetables, which falls on the lower end of 14, is fed into a container 16 installed outside the machine frame 10.

A spraying mechanism 17 for spraying water into the empty bag 2 is provided above the machine casing 10. This spray mechanism 17
A spray nozzle 19 is provided so as to project toward the center of the bag holding mechanism 12 by the electric cylinder 18, and a blower 20 and a water tank 21 are connected to the spray nozzle 19 to atomize the water and empty the empty bag 2. I am trying to jet to. 22 is
It is a constant-quantity discharge pump that discharges water in fixed quantities.

The bag holding mechanism 12 is provided with an upper partition plate 24 having a circular hole 23 formed in the lower center of the opening 11 opened in the upper center of the machine frame 10, and a holding rod 25 is attached to the upper partition plate 24. The operating plate 26 provided is provided so as to be movable up and down, and when the operating plate 26 moves downward, the holding rod 25 rotates downward and engages with the bag mouth of the opened empty bag 2. The bag take-out device 13 is configured such that a support base 29, which obliquely supports the bag container 1 with a pivot shaft 27 and a spring 28, is slid below the bag holding mechanism 12. It is composed of a take-out arm 8 for taking out the bags 2 one by one, and an opening arm 30 for opening the bag mouth of the empty bag taken out by the take-out arm 8.

A horizontal rod 9 is fixed to the tip of the take-out arm 8,
Draw-out rods 4, 5, 6, 7 are loosely fitted to the horizontal rod 9 at substantially equal intervals, and projected toward the container 1 side by compression springs 31, 32, 33, 34. An adhesive portion containing an adhesive is provided at the tips of the drawer rods 4, 5, 6, 7 and the empty bag 2 is adhered by the adhesive surface 3 at the tip thereof. It is projected longer than the rods 4, 7. Therefore, when the empty bag 2 in the bag container 1 is taken out, the state becomes as shown in FIG. 3 through FIG. 1 and FIG. There is no need to pull the bag 2 out.

When packing the vegetables into bags, when the work switch 35 is pressed, one empty bag 2 in the bag container 1 is taken out by the bag take-out device 13, held in the bag holding mechanism 12, and then sprayed by the spraying mechanism 17. Spray water into bag 2. After that, empty the vegetables by hand 2
Insert inside. When the work switch 35 is pressed again, the bag 2 is released and dropped to be stored in the container 16 via the chute 15 and the conveyor 14, and the next empty bag 2 is held by the bag holding mechanism 12 in the same manner as described above and the water is stored in the bag. It will be in a state where it can be sprayed and vegetables can be inserted and it stands by.
