The automatic folding and insertion of the workpiece 5 into the bag by the device of the present invention are as follows:
As is already clear from the explanation of each part, this is carried out as follows. That is, by placing the workpiece 5 in a straight posture on the conveyor 8 in the folding section 1 and driving the conveyors 8 and 9 in the direction of the arrow P, the workpiece 5 is carried over the conveyors 8 and 9. , the leading edge of the sheet is detected by the sensor 14, and the conveyors 8 and 9 are stopped. At the same time, the stopper 24 in the mount supply section 2 is retracted, and the mount is picked up by the mount picker 19 and fed into the guide notch 18c. One sheet of mount 6 is sent out by the feed roller 60 and the pinch roller 22, and then the guide roller 25,
25 to the center of the workpiece 5, and by driving the conveyors 8 and 9 again in the P, P/arrow directions, the workpiece 5 is inserted into the folding gap 13 with the insertion of the mount 6.
While being folded into a trifold shape, it moves straight downward and descends into the support bracket 11, and when the lower end is detected by the sensor 15, the pusher 12 moves forward, and the bifold workpiece 5 is further folded into a bifold shape with the built-in mount 6 and transferred to the conveyor. The workpiece 5' is pushed between the receiving conveyors 10 and 8, and the workpiece 5' folded into four from the same conveyors 8 and 10 is moved onto the transport conveyor 28 in the loading section 3, and is moved to the side guides 30, 30 and the open lower attachment 32, 32 is sent to a conveying end equipped with a pusher 33. On the other hand, the bag 7 made from the material film 7' in the bag supply section 4 is transferred to the bag drawer belt 44 and the nip belt 5.
3, the bag 7 is transferred onto the bag supply conveyor 45, transferred to the conveyor belts 46, 46a and the pressing belt 47 side, one side of the bag 7 is supported by the stopper 51, belt conveyance is stopped, and the bag 7 is transferred to the loading section 3. The folding workpiece 57 is positioned at the conveyance end with its opening 7a facing directly, and in the negative pressure zone due to air suction, the opening 7a is expanded by the opening lower attachments 32, 32, and the folded workpiece 57 is placed on the backing paper. 6 and is pushed by the pusher 33 and inserted into the bag 7 through the opening 7a through the tapered side guides 30, 30,
And it will be carried out together with the bag 7.

This bag 7 can be made in advance and separately supplied to the single-sheet conveyance end, and does not necessarily have to be made at the same time as bag making. The feature of the device of the present invention is that the mount supply section 2 and the charging section 3 are arranged above and below the folding section 1 in parallel and in series, so that the main mechanisms are compactly integrated into a short length. This, together with the arrangement of only the bag supply section 4 on one side, makes the entire equipment more compact and makes effective use of space by using the space above and below, which eliminates oversizing and unnecessary wastage of space, making the existing factory space more efficient. Furthermore, during folding, the mount supply section 2 supplies the mount 6 one by one, and the mount can be accurately and easily supplied at the folding position of the workpiece 5, and the timing can be easily matched with the folding timing. , the internal intervention of the mount 6 is facilitated, and therefore folding is also facilitated, and no deformation or mistakes occur.

The folding process is smooth and trouble-free due to repeated vertical and horizontal folding operations, and by repeating this two-step folding process, even long items can be easily folded down to the required size. The folding capacity can be easily adjusted by slowing down the relative speeds of the conveyors 8, 9, and 10, making it extremely versatile. Furthermore, since the extraction and supply of each sheet of the mount 6 is performed using the mount picker 19 using an air suction method, the extraction of each sheet is reliably facilitated without mistakes, and the feeding speed is high regardless of the thickness of the mount material. It can also be easily adjusted by the rotation speed of the feed roller 60, and can be quickly adapted to the size of the mount, providing great versatility. Furthermore, the charging operation in the charging section 3 is controlled by the rotatable lower attachment 32, the fixed side guide 30, and the pusher 33.
The workpiece 5' on the bag 7 can be loaded smoothly and accurately straight through the opening 7a of the bag 7, and air can be sucked into the bag 7 by the conveyor belts 46, 46a and the presser belt 47 in the bag supply section 4. Therefore, even the bag 7 made of thin plastic film material etc. can be transferred smoothly, and the opening 7
Expansion of a is also significantly facilitated, and both workpieces 5'
It is possible to charge without causing any trouble, and its folding,
The series of charging operations can be automated extremely efficiently and without waste, and by simplifying each part mechanism, causes of malfunctions and failures can be eliminated, and a series of simple and stable automatic controls can be achieved. In particular, it is suitable for use in folding various secondary processed fabric products, etc., and inserting them into bags, and is expected to expand the scope of use. Conventionally, this type of automation device exists, but the device of the present invention has particularly great advantages in the following points.

That is, in the present invention, in the folding section 1, the workpieces 5 are placed on a pair of conveyors 8 and 9 that are disposed opposite each other with a folding gap 13 in between.
By passing the mount 6 across the rack and vertically lowering the mount 6 from above the work 5 toward the gap 13, the work 5 can be folded in two by the mount 6 without the need to grip the work 5. At this time, the mount 6 work 5 is conveyor 8, 9
As it passes while being held by the
The two-fold shaping can be achieved smoothly and stably without fear of deformation or damage to the workpiece 5, and furthermore, the gap 13
A bracket 11 supports the lower end of the workpiece 5 mount 6 that has passed through the
, and the upper end is held between conveyors 8 and 9.
By pushing the pusher 12 between the conveyor 8 and the receiving conveyor 10, the four-folded work piece 5 can be easily obtained, and the four-folded workpiece 5 mount 6 is held and shaped between the conveyors 8 and 10 without slack, and then transferred to the loading section 3. Because the paper is sent to the same location, it is reliably shaped without the risk of shifting, wrinkling, or deforming. In this way, the workpiece 5 can be folded and shaped while utilizing the wide conveyor surfaces of the conveyors 8, 9, and 10 without having to pinch or grip it, and there is no risk of damaging the workpiece 5, and it is extremely efficient. In addition, in the charging section 3, the pusher 33 opens the lower attachment 3.
2 and 32, the workpiece 5 is pushed into the bag 7 without being held, so that it does not deform or shift its position, and is conventionally used to handle soft workpieces such as socks that are easily deformed or damaged. This is superior to devices that tend to lose their shape or deform when the socks are gripped or lifted and folded, and the entire device can be extremely simplified.
