Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an insertion method for expanding a film-like tube and inserting an article into the tube.

The structure of the conventional example and its problems Inserting an article into a film-like tube is explained in terms of the relationship between, for example, a dry battery unit cell and a tube that covers it. This was accomplished by preparing a tube 1, preparing a separately completed unit cell 2, and inserting this into the expanded tube 1 as shown in FIG.

The specific method is shown in FIG. First, as shown in Fig. 4, a film-like tube 1 cut to a certain size is sucked from both sides with a vacuum suction function or a loop-like attachment 3 to open the tube 1, and a spindle-shaped guide rod is inserted inside the tube 1. 4 and insert the cell 2 into the tube 1.
It is sandwiched between the button shear 6 and the outer side of the button. At this time, the tip of the guide rod 4 retreats to receive the terminal of the unit cell 2 without damaging it. Next, the pusher 6, the battery 2, and the guide rod 4 move from right to left in this state (the fourth
Figure B).

The movement further progresses from right to left, and guide rod 4 moves to chi soup 1.
The unit battery 2 is pushed by the pusher 6 as it retreats outward.
is pushed into the tube 1 to complete the insertion.

If the axial center of the unit battery 2, which is a cylindrical article, is tilted with respect to the axial center direction of the guide rod 4 and the pusher 6, or if the spread state becomes uneven vertically or horizontally due to the attachment 3 of the tube 1, it will be a problem. There have been problems in that the tip of the battery gets caught on the end of the tube 1 and damages the tube, or the end of the label attached to the outer periphery of the cell hits the end of the tube and is damaged. Furthermore, the speed at which the article is inserted into the tube cannot be increased because it is affected by the reciprocating movement of the guide rod and pusher.

Purpose of the Invention The present invention solves these conventional problems by using a hollow article supply jig equipped with an easily expandable article insertion guide at the tip, and prevents damage to tubes and labels applied to articles. The purpose is to insert articles into the tube at high speed without having to do so.

Structure of the Invention In order to achieve the above-mentioned goals, the film-like chew of the present invention,
- The method of inserting articles into the tube is to expand a film-like tube cut to a certain size into a hollow state using an attachment with vacuum suction power, and then insert the article into one end of the tube, which is provided at the tip of a hollow article supply jig. A guide is inserted, the article insertion guide is made up of a plurality of strip-shaped elastic thin plates arranged in a tapered state, and a pusher is used to push out the article located in the jig toward the guide side, causing the elastic thin plates of the guide to move outward. The feature is that the article is inserted into the tube while being expanded.

Hereinafter, the detailed structure and operation of the present invention will be explained using examples.

DESCRIPTION OF THE EMBODIMENTS FIG. 5 shows a hollow article supply jig which is a feature of the present invention, and is provided with a hollow portion large enough to allow the unit cell 2, which is an article, to pass through.

The jig 6 includes a plurality of strip-shaped elastic thin plates T arranged in a tapered shape and fixed to a hollow jig main body 9 by a cap nut-shaped collar 8. The screw mount portion of the jig body 9 is provided with a shallow inclined groove 10 for positioning and fixing the elastic thin plates 7, and each elastic thin plate 7 is installed in a tapered state by this groove 10.

The unit cell 2, which is an article, is inserted into the film-like tube 1, as in the conventional example, by vacuum suctioning the tube 1 cut to a predetermined size with the attachment 3 to form a hollow state, and attaching one end of the tube 1 to the tip of the jig. Insert the tip of the article insertion guide made of a tapered strip-shaped elastic thin plate. Next, the unit cell 2 is pushed from the rear end of the jig 6 with the pusher 5 and inserted into the jig 6.

The unit cell 2 pushed by the pusher 6 passes through the hollow part of the jig 6 and reaches the article insertion guide part, and the unit cell 2 is inserted into the tube 1 while pushing the elastic thin plate 7 inside the tube outward. Insert into.

According to this method, when inserting the unit cell 2, which is an article, into the tube 1, it is guided by the strip-shaped elastic thin plate 7, which is a guide, and the article does not come into direct contact with the end of the tube, so it is certain that the tube is not damaged. can be prevented.

Moreover, even if a label or the like is attached to the unit cell 2, which is an article, the label does not hit the end of the tube, and is guided by the elastic thin plate without strain and passes through it, so that the label is not damaged.

Effects of the Invention As described above, according to the insertion method of the present invention, the article can be smoothly inserted into the tube without damaging the cylindrical label that was damaged at the end of the tube when inserting the article into the tube. . Moreover, since the only operations required are inserting the article insertion guide of the jig into the tube and pushing the article using the pusher, the article can be inserted into the tube at high speed.
