[0004]

However, in the above-mentioned method, the one folded along the perforations 5 is sent to the margin slitter by the pin tractor b, but the continuous foam is folded in half or only a part thereof is folded. In the case of folding, the margin with pin holes does not come to both sides of the folded foam, so smooth feeding cannot be performed, which is a problem. Therefore, as shown in FIG. 11, using a continuous foam in which only perforations 4 extending in the width direction are formed and no perforations are formed in the feed direction (perforations may be formed in the feed direction). A device for making postcards has been proposed.

FIG. 12 shows the same apparatus, in which the continuous form is cut and separated at the perforation position of the continuous form in the feed direction of the continuous form, and is fed to the belt conveyor g as a single sheet. Then, the cut sheet is fed by the belt conveyor g in a direction orthogonal to the feeding direction of the burster f, folded by the folding mechanism h, and crimped by the crimping roller i to form a postcard. A pair of aligning conveyors j, j extending along the conveyance path are provided in the cut sheet conveyance path of the conveyance belt conveyor g so that the state of conveyance of the cut sheet to the feed roller h ₁ becomes appropriate. There is.

In the above-mentioned aligning conveyors j, j, the aligning conveyors j are arranged on both sides of the carrying belt conveyor g at the time of assembling, and the position of the aligning conveyors j can be adjusted by adjusting the entire aligning conveyor in the width direction of the carrying belt conveyor g. It has to be moved and adjusted, which is very troublesome. Also, since the contact time with the aligning conveyor of the cut sheet is long, there is a risk that the cut sheet will be caught by the belt surface of the aligning conveyor and the alignment state will be broken,
Further, the alignment conveyor has a complicated structure and is costly. In particular, in order to convey a large amount of postcards at a high speed, the conveyor belt conveyor g of the same apparatus conveys the preceding slips with the trailing end of the preceding cut and the front end of the following cut, and feed rollers h of the folding mechanism h. ₁ has a structure in which single sheets are pulled in one by one at high speed, and a slight deviation in positional accuracy has led to the generation of defective products as shown in FIG. 13 in which the side edges are not even.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a conveying device capable of conveying a single-cut sheet to a retracting device in a properly positioned state.

[0008]

In order to achieve the above-mentioned object, in a conveying device according to the present invention, a feeding device for continuously feeding a single cut and a single sheet sent by the feeding device. In a conveying device provided with a retracting device for retracting each of them, the feeding device is provided with a pair of cut sheet aligning guides that face each other across a conveying path of the cut sheet and that expands and contracts in synchronization.

It is configured so that it can be rubbed in a direction.

[0010]

The pair of alignment guides synchronously expands and contracts, and aligns the cut sheets being conveyed by the feeding device. In the present invention, since the pair of alignment guides are interlocked with each other while maintaining the parallel state to perform the rubbing motion in the moving direction of the single-cut sheet, the feed speed is adjusted by adjusting the rotational speed of the crankshaft to the single-feed speed of the feeding device. No load acts to prevent the movement of the cut sheets carried by the device.

Next, the operation of the postcard creating apparatus having the above configuration will be described. 2 to 4, the continuous foam 10 in a folded state is set at the front end of the device. Then, the pin tractor 20 pulls out the continuous foam 10 in the feeding direction, and the margin slitter 22 removes the margin areas 10a on both side edges of the running continuous foam. The continuous foam from which the margin area has been removed is then sent to the burster 30, cut at the position of the perforation 11 extending in the width direction, and cut as a cut sheet 15. The cut sheet 15 is discharged from the burster 30 onto the conveyor belt conveyor 40. The belt conveyor 40 conveys the received cut sheets 15 in a partially overlapped state, and the cut sheets 15 are aligned by the alignment guide mechanism 42 and fed to the folding mechanism 50 during the process. A pair of feed rollers 52a and 52b are provided on the inlet side of the folding mechanism 50, and the feed rollers 52 (52a and 52b) rotate at a peripheral speed much faster than the speed of the belt conveyor 40. Therefore, as soon as the front end of the cut sheet 15 is bitten by the feed roller 52, the cut sheet 15 is immediately drawn into the folding mechanism 50. At this time, the succeeding single-cut sheet 15 is pressed by the pressing roller 56, so that there is a problem that the succeeding single-cut sheet is pulled into the preceding single-cut sheet, that is, the single-cut sheets are supplied to the folding mechanism 50 in an overlapping state. Absent. Then, the single sheet folded by the folding mechanism 50 is then pressed by the pressure roller 60.
Thus, the pressure-sensitive adhesive application surface is pressure-bonded to form a postcard to which the folded-back portion is adhered. Then, the formed postcard is discharged by the conveyor belt conveyor 62.

[0022]

As is apparent from the above description, according to the conveying apparatus of the present invention, the pair of alignment guides perform the expansion / contraction operation in synchronism with each other so that the single sheet fed by the feeding apparatus is moved to the drawing apparatus. On the other hand, since the chips are always aligned in the proper position in the width direction, the single-cut sheet is always drawn into the drawing device in a proper state, and the degree of occurrence of defective products is significantly reduced.

According to the second aspect of the present invention, the pair of alignment guides horizontally rotate (gripping motion) in the single-sheet feeding direction while maintaining the parallel state. However, the rotation speed of the alignment guides is the single-sheet feeding speed of the feeding device. By doing so, since no load is applied to the single-cut sheet in the feeding direction in the front-rear direction, it is possible to significantly reduce the occurrence of defective products even when the single-cut sheet is fed at a high speed by the feeding device. ..
