DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for winding up a plurality of rows of blanks discharged in a tape form from a blanking machine for punching a plurality of rows of band-shaped blanks. Things.

[0002]

2. Description of the Related Art FIG. 1 shows a label punching device a and a scrap cake winding device b provided downstream of the label punching device a. A label sheet c stuck on a backing paper is a punch device d of the label punching device a. , E, are punched in a row and in a predetermined shape in each row, and the lump f between the rows generated at this time is formed into a tape as shown in FIG. It can be rolled up. The punched label g travels to the downstream side in a state of being attached to the backing paper.

[0003] The above-mentioned conventional waste cake winding device b is provided with a tape-like waste cake f of each row peeled off by a peeling guide roller h.
Are sequentially wound up in a disk shape on a winding paper tube j via a guide roller i. Rolled up paper tube j
Is rotated by a driving unit via a slip clutch, and is slid and rotated by winding resistance.

[0004]

SUMMARY OF THE INVENTION One wound paper tube j
When a plurality of tape-shaped scraps f is wound up in a row in a row, the width of each of the scraps f is narrow,
The winding disks in each row are unlikely to be perfect circles, and the winding progresses, and as the diameter increases, the outer diameter of the winding disk becomes irregular, such as an ellipse. For this reason, when the winding disks in each row are wound up and rotated at the same peripheral speed by the winding paper tube j, a variation occurs in the winding radius of each winding disk. The winding tension changed every rotation of the winding disk.

[0005] In the conventional apparatus for winding up scraps, the scraps f from the peeling guide roller h to the winding paper tube j are guided by the guide roller i.
In this case, the fluctuation of the winding tension of the above-mentioned draft f cannot be absorbed, and the fluctuation of the tension causes the draft to meander, causing the winding disk to lose its shape in the thickness direction or to be cut by an instantaneous tension. And other problems. For this reason, the winding cannot be continued until the winding disk becomes too large, and the winding cannot be performed at a high speed.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and provides a certain tension to each row of swarf, without sagging individual swarf rows, and without abrupt tension fluctuation. It is an object of the present invention to provide a scrap cake winding device capable of winding.

[0007]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an apparatus for hoisting scraps, in which a large number of tape-shaped scraps are wound by a single winding shaft which slides and rotates. In the drafting wire winding device, a tension roller for applying tension to each drafting meal is provided at a winding section of each winding row.

[0008]

[Operation] Each of a plurality of rows of tape-shaped scraps wound up by one winding shaft is wound up while being provided with an appropriate tension by a tension roller, and the scraps in each row drop off from a winding disk. It can be wound on a large winding disk at high speed without cutting or cutting.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to FIG. FIG. 3 is a front view showing the draft meal winding device 1 according to the present invention. In the drawing, reference numeral 2 denotes a peeling guide roller for guiding the tape-shaped scrap 4 while peeling it from the label paper 3, and reference numeral 5 denotes a winding paper tube for winding up the scrap 4. As shown in FIG. 4, the wound paper tube 5 has a tapered support 6
The rotary shaft 6 is supported by the opposing surfaces of a and 6b, and is rotated via the tapered supports 6a and 6b. The rotating shaft 6 is connected to a drive mechanism 8 via a known friction clutch 7.

The drive mechanism 8 drives the rotary shaft 6 to rotate at a speed at which the peripheral speed of the outer periphery of the wound paper tube 5 is equal to or slightly higher than the running speed of the label paper 3. In addition, the friction clutch 7 is configured such that the rotating shaft 6 slips with respect to the drive mechanism 8 when a braking force is applied to the wound paper tube 5.

Guide rollers 9 and 9 are arranged in a path leading to the peeling guide roller 2 and the winding paper tube 5. The guide rollers 9 on the downstream side of the guide rollers 9 and the tension rollers 10, 10 which are in rolling contact with the scrap 4 wound up by the wound paper tube 5 on the path leading to the wound paper tube 5 and apply tension thereto are arranged. Have been.

The tension roller 10 is rotatably supported by a swing lever 12 of a tension roller device 11 shown in FIG. The tension roller device 11 has a base 15 movably supported by two support rods 14 a and 14 b provided on a frame 13, and is rotatable on the base 15 in a direction crossing the path of the extracted cake 4. A supported swing lever 12, and a spring 1 for urging the swing lever 12 to one side.
6 and a spring support 17 for supporting the spring 16. The spring receiving base 17 is fixed on the base 15 so as to be movable in the biasing direction of the spring 16. The spring 16 and the swing lever 12 are connected by hooking one end of the spring 16 to a pin 19 engaged with one of a plurality of pin holes 18 provided in the longitudinal direction of the side surface of the swing lever 12. At this time, by selecting one of the pin holes 18, the force in the turning direction of the swing lever 12 can be changed. 20
Is a handle for fixing the base 15 to the support rod 14b.

Next, a description will be given of an operation of winding the tape-shaped scrap 4 from the punched label paper 3 with the scrap-winding device 1.

In FIG. 3, the tape-shaped scrap 4 peeled from the label paper 3 on the downstream side of the peeling guide roller 2 is passed between the guide rollers 9, 9, and the tension rollers 10, 10, and the leading end thereof is wound up and the paper tube 5 is wound. Glue to Then, the machine is driven to run the label paper 3 and the wound paper tube 5
The sliding drive.

The extracted cake 4 of the label paper 3 is
Is peeled off by the peeling guide roller 2 as it travels, is wound up by the winding paper tube 5 via the guide rollers 9 and 9 and the tension rollers 10 and 10, and is sequentially laminated in a disk shape. The wound paper tube 5 is slidably driven by the friction clutch 7, and as the wound diameter increases, slipping occurs due to the braking action by the tension of the extracted cake 4,
It is rotated at a substantially constant peripheral speed.

At this time, a predetermined tension is always applied to each of the scraps 4, 4... In each row by tension rollers 10, 10 before being wound up in a disk shape. As a result, the outer periphery of the disk on which each row of the scraps 4 is wound has an elliptical shape such as an elliptical shape, and even if the winding radius changes during one rotation and the winding speed partially changes, this winding is performed. Fluctuations in the winding tension of the scrap 4 due to fluctuations in the speed are absorbed by the tension rollers 10, 10.

Accordingly, the shape of the disk for winding up the scraps 4 in each row changes for each row, even though the plurality of scraps 4 is wound up at a uniform rotation speed by the rotation of the winding paper tube 5. Also, the extracted cake 4 in each row is rolled up without cutting or slack due to a sudden change in tension and without meandering. In addition, since the tension is uniform in each row, even when the winding disk has a large diameter, the winding can be performed with high density without winding collapse and can be wound at high speed for a long time.

The position of the tension roller 10 with respect to the scrap 4 is adjusted by moving a tension roller device 11 that supports the tension roller 10 along support rods 14a and 14b. Further, the urging force of the tension roller 10 is adjusted by the pin hole 18 on which one end of the spring 16 is engaged with which pin hole 18 and the fixing position of the spring receiving base 17 to the base 15. FIG. 3 shows an example in which the tension roller device 11 is provided at two places. However, if the winding shape is severely distorted, the eccentricity is severe, and the tension fluctuation of the scraps 4 is severe, the tension roller device 11 is installed. By increasing the number of places or increasing the swing amount of the swing lever 12 to lengthen the paper path, the fluctuation of the winding tension of the scrap 4 is absorbed. Of course, depending on the situation, the tension roller device 11 may be installed at one location.
