Abstract

PURPOSE:To certainly transfer a buckling paper and hence to enable the stable operation without any trouble secularly by separatively pushing a buckling paper at the position where the belt of a first transferably attracting roll is separated and transferred, and transferring the buckling paper to an attracting portion side of a second transferably attracting roll. CONSTITUTION:A belt 15 is inserted in an annular groove in at least a transfer region, and is engaged in such a manner as not to be interfered with the attraction of attracting portions 2 and 4 and the transfer of a buckling paper 10a. In the opposed positions of both rolls 1 and 3 where the attracting portion 4 of a second transferably attracting roll 3 exerts the attracting action to a buckling portion 4b, the belt 15 is separated from the first transferably attracting roll 1 and is moved toward the other running end. Accordingly, the belt 15 separatively pushes the buckling portion 10b of the buckling paper 10a from the attracting portion to the side of the second transferably attracting roll 3 immediately after being separated from the first transferably attracting roll 1, thus supporting the attraction by the attracting portion 4. Therefore, the buckling paper 10a is certainly transferred from first transferably attracting roll 1 to the second transferably attracting roll 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a waist origami transfer device that reliably transfers waist origami such as napkins from a ¥%1 transfer suction roll to a second transfer suction roll.

Prior Art While the first transfer suction roll rotates, the napkin is folded and cut, and is adsorbed to the second transfer suction roll and transferred to the same roll for the next process, for example, a stacking process. The problem is preventing transfer errors when the suction roll rotates at high speed. Conventionally, for example, a pushing away means such as a paper gripping claw is provided at the suction site of the first transfer suction roll, and the paper gripping pawl is opened and closed in a timely manner to push the waist origami away from the suction site of the 18th feed suction roll. Examples have been proposed in which it is pressed against the suction site side of the second transfer suction roll.

Problems to be Solved by the Invention However, since the above-mentioned filling means is timed by a peripheral cam or a return spring, the structure is not only complicated, but also causes wear of the cam, deterioration of the spring, etc. There are many mechanical instability factors, and transfer errors tend to occur, making it difficult to maintain stable operation over time and making it difficult to keep up with higher speeds. Also, the impact and noise generated when the pushing and releasing means is opened and closed also poses problems.

The present invention fundamentally solves these problems, and even under high-speed operation, the waist origami can be reliably transferred from the first transfer/adsorption roll to the second transfer/adsorption roll, and stable operation without trouble over time can be expected. This invention provides a device for transferring origami.

Means for Solving the Problems The present invention provides, as the above-mentioned means, that when the gripping origami is transferred from the first transfer suction roll to the second transfer suction roll by suction, one or more strips are attached to the first transfer suction roll. It is configured to move the strip belt, push and release the waist origami at a portion where the belt moves forward and backward from the 18th feeding suction roll, and transfer it to the suction section side of the second transfer and transfer roll. This is what I did.

Function As described above, the belt is simply allowed to feed endlessly as the first transfer suction roll rotates, and during the feeding process, the belt origami is naturally and effortlessly pushed away from the suction portion of the first transfer suction roll. 2. Transfer can be transferred to the adsorption roll and transferred to the next process. Therefore, the structure is extremely simple and reliable transfer is possible. There are no factors that cause wear or rattling, and operation is stable over a long period of time. can be expected.

Example The present invention will be explained below based on an illustrated embodiment.

Reference numeral 1 denotes a first transfer/adsorption roll, and the first transfer/adsorption roll 1 has a suction section 2 formed on its circumferential surface by air suction. Reference numeral 3 denotes a second transfer suction roll, and the second transfer suction roll 3 has a suction portion 4 opened on its circumferential surface.

Above 1. The second transfer suction rolls 1.3 rotate relative to each other while facing each other, and the suction portion 2 of the first transfer suction roll 1 is substantially opposed to the suction portion 4 of the second transfer suction roll 3 at the opposing portion of both rolls. Each suction part 2.4 is formed
Allocate.

- For example, when the first transfer/adsorption roll 1 makes one rotation and the second transfer/adsorption roll 3 makes a half turn, the adsorption portions 2.4 are arranged so as to substantially face each other. That is, the suction part 2 is arranged on the 's1 transfer adsorption roll 1 at a position where the rotation period is 360 degrees, and the above-mentioned adsorption part 4 is arranged on the second transfer adsorption roll 3 at a position where the rotation period is 180'. Then, set the diameters of rolls 1 and 2 to fit the mold.

Reference numeral 15 denotes a belt suspended on the first transfer suction roll 1, and the belt pushes away the waist fold part tab of the waist origami 10a from the first transfer suction roll 1 side to the second transfer suction roll 3 side, It serves as a pushing and separating means to supplement the transfer. Details will be described later.

The other one 5 is a cutter roll which is disposed at a position substantially opposite to the second transfer/adsorption roll 3 and rotates relative to the first transfer/adsorption roll 1 . The cutter roll 5 includes a crimp blade 6 whose cutting edge slightly protrudes from the circumferential surface and a single-rotation blade 7. For the above crease, the blade 6 is the cutter roll 5.
and the band 1 which is substantially opposed to the suction section 2 at the opposing portion of the 1f multi-feed suction roll 1 and introduced between the two rolls 1 and 5.
Press the tip of the blade onto the 0 to make a crease. For example, in the creasing process, the blades 6 are arranged so as to face each other just before the suction portion 2 of the first transfer suction roll l at one revolution of the cutter roll 5, that is, with a rotation period of 360', and the rotary blade 7 is arranged to face the suction part 2 of the first transfer suction roll l. Folding is done with blade 6. Folding is done with back band paper 10.
Arrange to cut. The cutting position is such that the blade 6 is used to create the creases ζ and cut the band after the edge has been drawn out by a certain amount, and the installation position is determined according to the amount of protrusion a. Therefore, in the embodiment, the kerf is arranged behind the blade 6 so as to match the fixed blade 8 with a rotation period of 360'.

The fixed blade 8 is disposed on the paper introduction side of both rolls 1.5, and cuts the previously crimped paper band at the rear into unit lengths.

Reference numeral 9 denotes a roll for feeding out the band 10, and the band 10 is fed out between the first transfer suction roll 1 and the cutter roll 5 by the feeding roll 9. On the paper guide side of the feed roll 9, there is a paper guide 1 that supports the lower surface of the paper and guides its movement.
1, and the fixed blade 8 is provided at the end of the paper pressing guide 11, and the band 10 is guided by the band guide 11 to the fixed blade 8, and then passes through the fixed blade 8 and heads between the two rolls 1.5. Make it.

Reference numeral 12 denotes a waist folding roll, and the waist folding roll 12 is arranged to face the circumferential surface of the first transfer/adsorption roll 1 between the cutter roll 5 and the second transfer/adsorption roll 3. That is, a waist origami transfer area is formed from a portion of the first transfer suction roll 1 facing the cutter roll 5 to a portion facing the second transfer suction roll 3, and the waist folding roll 12 is located in the middle of the waist origami transfer area. are arranged so as to rotate relative to the first transfer/adsorption roll 1.

As shown in FIG. 1, when the leading edge of the band 10 is fed out in a fixed amount such that it reaches the upper part of the waist folding roll 12, the folding blade 6 is moved to the first transfer suction roll 12.
The cutting edge is pressed against the paper band 10 supported by the first transfer/suction roll 1 to crease it.

In order to accurately form the folds, an elastic material 13 is provided on the suction portion 2 of the first transfer suction roll l, and the cutting edge of the blade 6 is bitten into the surface of the elastic material 130 to form the folds. Immediately after that, the suction section 2 suctions and holds the material.

As shown in FIG. 2, the folded paper band behind the waist-folding roll 12 is folded into the roll 1 by the suction unit 2 as both rolls 1.5 rotate (the band paper is fed out). .12 The rotary blade 7 is pulled in between 12 and performs waist folding by applying pressure, and the rear fixed blade 8 is used for the waist folding
Cut the banding paper fed out in a fixed amount from several parts of the waist folds that are compatible with the paper. The cutting timing is performed after the bow is cut between the rolls 1 and 12. Or, depending on the length backward from the waist-folding part, it is cut just before it is drawn between the rolls 1 and 12.

As shown in FIG. 3, the waist-folded paper 10a such as a napkin paper is suction-held at the waist-folded portion 10b by the suction unit 2, and is transported toward the second transfer suction roll 3. The suction portion 4 of the roll 3 acts on the portion facing the roll.

That is, the suction part 4 is in a state opposite to the suction part 2, and exerts a suction action on the folded part 10b from the opposite side of the suction part 2.

The belt 15 is attached to the first transfer suction roll 1 as described above.
to hang. The belt 15 uses, for example, a plurality of round belts each having a circular cross section. On the other hand, a plurality of annular grooves 14 are formed at intervals in the axial direction on the circumferential surface of the first transfer/adsorption roll 1, and one rotating end of the belt is fitted into the annular groove 14, and this is used as a guide. An adjustment roll 1 which is hung so as to shift and whose other rotating end is spaced apart from the first transfer adsorption roll l.
The belt 15 is suspended so as to run endlessly between both rolls 1 and 16, and one end of the belt 15 relative to the first transfer suction roll is moved along the circumferential surface of the roll in the waist origami transfer area. Multiply as follows. That is, in the illustrated example, the first transfer suction roll 1 and the cutter roll 5 have been in contact with each other since at least before the part where the first transfer suction roll 1 and the cutter roll 5 face each other (in other words, the folding part is the part where the plate 6 and the elastic material 13 face each other). The area up to the vicinity of the area where the second transfer suction roll 3 faces (in other words, the area where the suction part 2.4 faces) is defined as the waist origami transfer area, and the belt 15 is moved at least into the annular groove 14 in this transfer area. The adsorption action of the insertion suction part 2.4 and the transfer of the waist folded paper 10a are combined so as not to interfere with each other, and the suction part 4 of the second transfer suction roll 3 exerts an adsorption action on the waist folded part 10b. The first transfer adsorption roll 1 near the opposite part of the roll 1.3
The direction is moved away from and toward the other turning end. As a result, the belt 15 pushes away the folded part 10b of the waist origami 10a from the suction section 2 toward the second transfer and suction roll 3 side immediately after leaving the first transfer suction roll 1, complements the suction by the suction section 4, and To surely perform transfer from a transfer adsorption roll 1 to a second transfer adsorption roll 2.

Preferably, the belt 15 is arranged to slightly overlap the circumferential surface of the second transfer/adsorption roll 3 in a region W in front of the adsorption section 4 facing the adsorption section 2, thereby making the transfer more reliable. Therefore, the adjustment roll 16 is the first transfer adsorption roll 1
The roller 1 should not move in the circumferential direction of the roll 1 as indicated by the arrow in the figure, centering on the roll 1. By this movement, it is possible to adjust the position at which the belt 15 leaves the roll 1 or the size of the W to be applied to the roll 3 to be appropriate.

Effects of the Invention As explained above, in the present invention, the belt is hooked onto the first transfer/adsorption roll and simply rotated endlessly along with the rotation of the roll, and in the process of the belt, the waist origami is formed naturally and effortlessly. Pushing from the suction part of the first transfer suction roll
By transferring the crucian carp to the transfer suction roll and transferring it to the next process, the structure is very simple and reliable fl
It is possible to perform stable operation over a long period of time, even though there are no factors that can cause wear and play. Furthermore, it is possible to provide a waist origami transfer device that does not cause transfer errors even during high-speed operation, and production efficiency can be greatly improved.
