BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet feeding apparatus for surely feeding sheet bodies such as a bag body in a filling and packaging apparatus and a label body fed into a mold of a blow molding machine one by one. Also, the present invention relates to a manufacturing apparatus for manufacturing a bag package and a resin container with a label provided with the same.

[0002]

2. Description of the Related Art As an apparatus for supplying a sheet body such as a plastic material, there is, for example, a bag body supply apparatus in a filling and packaging apparatus. In the filling and packaging apparatus, the bags supplied one by one are held by a plurality of sets of holding claws, and the bags are opened and closed by intermittent rotation of the holding claws, an opening part for opening a mouth, a filling part for contents,
The sealing part of the mouth part, the cooling part of the sealing part, and the discharging part of the bag body are sequentially moved to each process.

FIG. 13 shows a conventional bag feeding device. In this bag supply device, a large number of plastic film bags 1 are stacked in a magazine 2, and the magazine 2 is gradually moved by a lifting shaft 3 as the number of bags 1 at the top (the outermost part) is reduced. Will be lifted to. Also magazine 2
A fixed front stopper 4 is provided in front of.

At the upper position of the magazine 2, there is provided a suction plate 6 which rotates about a shaft 7. The suction plate 6 exerts suction force by negative air pressure at a predetermined timing, and the uppermost bag body 1 is sucked by this suction plate 6, and the suction plate 6 rotates clockwise in FIG. Thereby, the tip opening 1a of the uppermost bag 1 is lifted.
The tip opening 1a of the lifted bag body 1 is clamped by the pair of claws 5a and 5b of the swivel clamp member 5, and the swivel clamp member 5 rises in the swirl locus,
One bag 1 is sent upward. Then, the swiveling clamp member 5 directly or through another clamp member sequentially transfers to a plurality of sets of holding claws that intermittently rotate in the main body of the filling and packaging apparatus.

[0005]

However, in this type of bag feeding apparatus, in the magazine 2,
Due to the smoothness of the surface of the bags or the electrostatic attraction, the bags are easily attached to each other. Therefore, when the uppermost bag 1 is adsorbed and lifted by the suction board 6, two or three bags may be lifted together. Therefore, conventionally, for example, when the bag body 1 is sucked by the suction plate 6 and lifted,
In FIG. 13, air injection is performed from the direction indicated by the arrow (a) to separate the uppermost bag body 1 and the lower bag body from each other. It is not always possible to separate the bodies, and a phenomenon in which a plurality of bag bodies 1 are lifted up together often occurs.

When a plurality of bag bodies 1 are lifted up together by the suction board 6, the plurality of bag bodies are held together by the claws 5a and 5b of the swivel clamp member 5, and the holding claws of the main body of the filling and packaging apparatus are kept as they are. Will be handed over to. When a plurality of bags are held together by the holding claws of the main body of the filling and packaging device, when the mouth of the bag is to be opened, the mouth should be opened, but the plurality of bags are separated from each other. However, the bag cannot be filled with the contents. Further, such a problem is not limited to the supply of the bag body in the filling and packaging device.
For example, when the labels are supplied one by one into the mold of a so-called in-mold label type blow molding machine, there is a problem that two or more labels are simultaneously supplied as in the above case.

The present invention solves the above-mentioned conventional problems, and it is an object of the present invention to provide a sheet body supply device for supplying a bag body, a label or the like so that the sheet bodies can be surely sucked and supplied one by one. Has an aim.

The present invention also provides an apparatus for manufacturing a bag-filled package in which a bag is supplied using the above-mentioned sheet supply device.
Another object of the present invention is to provide an apparatus for manufacturing a suction-molded labeled resin container to which a label is supplied.

[0009]

According to the present invention, an edge portion of a sheet body passes when the outermost portion of a plurality of sheet bodies stacked on a mounting portion is sucked and conveyed by a suction member. For example, if a plurality of fine protrusions with appropriate elasticity and flexibility are provided in the area, and the edge of the sheet that is adsorbed and sent out slides on these fine protrusions, it vibrates finely and smoothness is improved. This is done paying attention to the fact that the sheet bodies other than the above-mentioned outermost sheet body that are attached due to static electricity, static electricity, or the like are very reliably separated or eliminated.

That is, according to the present invention, there is provided a sheet body mounting portion on which the sheet bodies are stacked and placed, and a suction member for holding and conveying the outermost sheet body. In the feeding device, a separating member that causes minute vibrations in the edge portion of the sheet body to separate the sheet body other than the outermost sheet body in a region where the edge portion of the sheet body held by the suction member passes. Is provided.

The separating member can be constructed by providing a plurality of fine projections on the surface.

Further, the manufacturing apparatus of the present invention uses the above-mentioned sheet body supplying apparatus, and by this, a bagging package manufacturing apparatus in which bags are supplied one by one, or labels are supplied one by one. It is an apparatus for manufacturing a suction-molded resin container with a label.

[0013]

In the above means, the separating member having a fine projection having the same structure as that of the resin fastener is provided in the region through which the edge of the sheet body sucked and sent by the suction member passes. When the edge portion of the sheet body slides on the separating member, the sheet body other than the one held by the suction member by vibrating the edge portion of the sheet body finely, for example, by a fine projection having appropriate elasticity and flexibility. Are separated, and only one sheet is reliably delivered. Therefore, the sheet supply device can reliably supply the bags one by one in the bag-filled package manufacturing device, and the suction-molded label-equipped resin container manufacturing device can surely supply the labels one by one. Can be supplied to.

The inner space of the bag body 1 is expanded. Further, in the content filling section C, the filling hopper 15 is inserted into the opened bag body 1.
The contents are filled from.

Next, the structure of the bag feeding device 20 will be described. The bag body supply device 20 is provided with a magazine 21 on which a large number of bag bodies 1 are placed in an overlapping manner.
When all the bags 1 in one magazine 21 have been used up and become empty, a new magazine 21 full of bags 1 is supplied through the path indicated by the arrow (b) in FIG. The magazine 21 is provided with a lifting mechanism 22, and the magazine 2
A bag upper limit sensor 23 is provided at a position facing above 1. With this configuration, when the bags 1 in the magazine 21 are adsorbed one by one from the uppermost one and discharged, and the number decreases, the bag upper limit sensor 23 detects the decrease and the lifting mechanism 22 causes the magazine 21 to move. Is a bag 1
It can be raised by a height corresponding to the decrease of.

A front stopper 24 is provided in front of the magazine 21. The front stopper 24 is fixed to the gantry 10, and the magazine 21 is opened in a direction facing the front stopper 24. Although the height of the magazine 21 changes from time to time by the lifting device 22, the positional relationship between the fixed front stopper 24 and the uppermost bag body is always kept unchanged.

As shown in FIG. 4, a concave portion 24a is formed in the center of the upper end of the front stopper 24, and a separating member 25, which is a feature of the present invention, is provided on the inner surface of the concave portion 24a. As shown as an enlarged cross-sectional view in FIG. 5, the separating member 25 includes a support plate 26 and a separation sheet 27 attached to the inner surface of the support plate 26. Support plate 2
Reference numeral 6 denotes an elastic plate member, which is preferably formed of a plate spring material such as a phosphor bronze plate or a spring type stainless plate, and the upper end of which is bent and deformed at a gentle angle so as to be directed toward the magazine 21. Has been done.

The separation sheet 27 is composed of a base cloth 27a and a large number of fine projections 27b planted on the base cloth 27a. It is preferable that the protrusion 27b is not so long as to project from the base cloth 27a, and is flexible with some elasticity. For example, a resin fastener is used as the separation sheet 27. As shown in an enlarged scale in FIG. 6, this resin fastener has a hook-shaped projection 2 made of a large number of resin fibers from a base cloth 27a in which resin fibers are woven.
7b is protruding. Since the hook-shaped projection 27b of this type of resin fastener has rigidity and elasticity to some extent, when the edge of the bag slides, a slight vibration is applied to the edge of the bag, As a result, it acts to brush off the excess bag. It is also possible to use a resin fastener (FIG. 7) in which a large number of loop-shaped protrusions 27b are planted in the base cloth 27a or a mushroom-shaped resin fastener having the protrusions 27b.

The structure of the separating sheet material 27 does not necessarily have to be a resin fastener, and may be, for example, a base cloth woven of resin fibers or a surface of felt or the like in which fibers are fluffed. The protrusions are not necessarily limited to those having elasticity and flexibility, and a large number of hard and extremely short protrusions may be formed on the surface of the resin plate. Furthermore, the separating member may be formed of a plate material having a large number of parallel grooves formed on the surface thereof, or a corrugated plate having a triangular cross section. Of course, in this case, the direction of the unevenness of the plate material or the corrugated plate is parallel to the direction of the tip of the sheet body.

In the separating member of the present invention, which is composed of a member having irregularities on the surface such as the above-mentioned resin fastener, plate material or corrugated plate, the edge of the sheet body simply slides on the surface of the separating member as the sheet body moves. It is passive, reliable, and effective in the sense that minute vibrations can be generated at the edge of the sheet to scrape off an excess sheet body just by moving. On the other hand, an active element such as a vibrator may be used as the separating member of the present invention.
