BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of a polybag removing apparatus according to the present invention. FIG. 1 is an exploded perspective view of a polybag removing device according to an embodiment of the present invention. The polybag removing device 1 includes a tray 2 which is a storage container for stacking and storing sheet-like polybags (polyback sheets) 8 described later. The upper part of the tray 2 is opened, and the front plate 2a, the left plate 2b, the right plate 2c, the rear plate 2d, and the bottom plate 2
e. The front side plate 2a has an opening 2 which is a cutout for taking out the sheet-shaped polybags 8 one by one.
a-1 is provided, and the width of the outlet 2a-1 is formed smaller than the width of the poly bag.

[0008] Holes 2b-1 and 2c-1 are formed near the rear upper ends of the left and right side plates 2b and 2c of the tray 2, respectively.
The shaft portions 3b, 3b at both ends of the pressing member 3 having an inverted U-shape in a plan view are inserted into the holes 2b-1, 2c-1, and are rotatably supported.

The pressing member 3 serving as the first pressing portion is for pressing the front portion of the sheet-shaped polybag 8 from above by its own weight, and is formed of, for example, a metal rod and has a U-shaped pressing portion 3a in plan view. Are formed integrally with the shaft portions 3b, 3b bent at substantially right angles at both ends thereof.

The holes 2b- in the left and right side plates 2b, 2c of the tray 2
Vertical grooves 2b-2 and 2c-2 extending in the vertical direction are provided at positions forward of the vertical grooves 2b-2 and 2c-1, respectively.
Small diameter shaft portions 5b, 5b at both ends of a holding bar 5 as a second holding portion are inserted into and engaged with c-2.
The holding bar 5 is for holding the rear portion of the sheet-shaped polybag 8 from above by its own weight, and is made of, for example, a metal round bar, and has a cylindrical portion 5a and small-diameter shaft portions 5b provided at both ends of the cylindrical portion 5a. , 5b. That is, the position of the holding bar 5 in the front-rear direction is restricted by the grooves 2b-2 and 2c-2, and the holding bar 5 is rotatable with respect to the grooves 2b-2 and 2c-2, and is vertically moved along the grooves 2b-2 and 2c-2. It is configured to be movable in the direction.

According to the present invention, the front portion of the sheet-shaped polybag 8 is pressed from above by the holding member 3 by its own weight, and the rear portion of the polybag 8 is pressed from above by the holding bar 5 by its own weight. By providing an outlet 2a-1 for taking out a polybag having a width smaller than the width, the sheet-shaped polybags stacked and stored in the tray 2 can be reliably pulled out one by one. is there.

FIG. 2 shows a polybag. The polybag 8 is made of a thin sheet made of polyethylene, and has an opening 8a, a side 8b, and a bottom 8c which is heat-sealed and sealed. A small article is supplied from the opening 8a of the polybag 8 and is filled in the polybag 8. When the polybags 8 are stacked in a sheet shape, the internal air is pushed out, the side portions 8b are in close contact with each other, and the openings 8a are closed. At this time, since the polybag 8 is a thin sheet made of polyethylene and is closely adhered to the opening 8 by the action of static electricity, the opening 8
a is completely closed.

FIG. 3 is a view showing a state in which the sheet-like polybags 8 are stacked and stored in the polybag take-out device 1. The holding bar 5 is removed from the grooves 2 b-2 and 2 c-2 of the tray 2, and the holding member 3 is rotated rearward to fall to the rear of the tray 2. Next, a large number of sheet-shaped polybags 8 are placed from above the tray 2 and stacked and stored on the bottom plate 2e. And the shaft parts 5b, 5b at both ends of the holding bar 5
Is inserted into and engaged with the grooves 2b-2 and 2c-2 of the tray 2, the rear portion of the sheet-shaped polybag 8 is pressed from above by its own weight, and the pressing member 3 is rotated forward to hold the pressing portion 3
When the front portion of the sheet-shaped polybag 8 is pressed from above by a, the polybag 8 is stored as shown in FIG.

FIG. 4 is a view for explaining a state in which the uppermost polybag 8 is taken out from the polybag take-out device 1. When the operator places his hand in the outlet 2a-1 and grasps and lifts the uppermost polybag 8A of the polybags 8 stacked and stored on the tray 2 and pulls it forward, the U-shaped pressing portion of the pressing member 3 is formed. 3a pivots slightly upward with the shaft portions 3b, 3b as fulcrums, and the pressing bar 5 rotates, so that the polybag 8A can be taken out smoothly.

At this time, the front portion of the polybag 8 is pressed by the weight of the pressing member 3, the rear portion is pressed by the weight of the pressing bar 5, and the width of the outlet 2a-1 is smaller than the width of the polybag 8. The second layer polybag 8B can be reliably prevented from sticking to the uppermost layer polybag 8A due to static electricity and slipping out of the tray 2.

Further, since the pressing portion 3a of the pressing member 3 can be rotated about the shaft portions 3b, 3b, the pressing portion 3a of the pressing member 3 is turned upward when the uppermost polybag 8A is taken out. Thus, the uppermost polybag 8A can be more smoothly taken out.

Accordingly, the front portion of the polybag 8 is pressed by the weight of the pressing member 3, the rear portion is pressed by the weight of the pressing bar 5, and an outlet 2a-1 having a width smaller than the width of the polybag 8 is provided. Therefore, it is possible to reliably prevent the second layer of polybag 8B from sticking to the uppermost layer of polybag 8A due to static electricity and slipping out of the outlet 2a-1 of the tray 2, and being stacked and stored. Sheet-shaped polybags can be reliably taken out one by one.

In the above embodiment, the pressing member 3
Although the holding portion 3a is formed in a U-shape in plan view, the shape is not limited to this, and it is a matter of course that the holding portion 3a may have another shape such as a U-shape or triangle in plan view.

Next, a description will be given of a polybag removing device according to a second embodiment. FIG. 5 is a perspective view showing a polybag removing device according to the second embodiment. The polybag removing device 10 according to the second embodiment includes a tray 2 ′, which is a storage container for stacking and storing the polybags 8. The tray 2 'has a pair of vertical grooves 2b-2, 2c-2 extending vertically in the left and right side plates 2b, 2c.
That is, two pairs are provided, the holes 2b-1 and 2c-1 are not provided, and the other configuration is the same as the tray 2 of the above-described first embodiment. The small-diameter shaft portions 5b, 5b at both ends of the holding bar 5 are inserted into and engaged with the two pairs of vertical grooves 2b-2, 2c-2 of the tray 2 ', respectively.
That is, two holding bars 5 are provided.

Therefore, the front portion of the polybag 8 is pressed by the weight of the holding bar 5, the rear portion is pressed by the weight of the holding bar 5, and an outlet 2a-1 having a width smaller than the width of the polybag 8 is provided. Therefore, it is possible to reliably prevent the second layer of polybag 8B from sticking to the uppermost layer of polybag 8A due to static electricity and slipping out of the outlet 2a-1 of the tray 2, and being stacked and stored. Sheet-shaped polybags can be reliably taken out one by one.

[0021]

As described above, according to the present invention,
The front part of the poly bag is pressed by the first pressing part,
The rear part of the poly bag is pressed by the second pressing part, and a notch for taking out the poly bag is provided. Therefore, the poly bag of the second layer is stuck to the uppermost poly bag by static electricity, so that the notch of the storage container is formed. It can be reliably prevented from slipping out of the paper bag, and the sheet-shaped polybags stacked and stored can be reliably taken out one by one.

For this reason, when taking out the uppermost layer polybag as in the prior art, the operator holds the second layer polybag by hand or slides the second layer polybag slipped out of the notch of the storage container. There is no need to return to the storage container, the work of removing the polybag can be performed extremely easily and quickly, and the workability can be improved.

Further, since the polybags can be taken out one by one without fail, the second layer polybags may stick out to the uppermost layer polybag and slip out of the notch of the storage container and scatter on the floor. Rather, the floor of the workplace can be kept clean.
