BRIEF DESCRIPTION OF THE DRAWINGS The drawings illustrate one embodiment of the present invention.
This will be described below.

The illustrated label printing machine employs a so-called intermittent feed type label printing machine in which a printing section employs a flat pressure type printing section, and a flat die in a punching section, and employs a circular pressure type printing section in a printing section. In addition, the present invention includes both a so-called continuous-feed type label printing machine employing a rotary die for a punching unit.

A support 13 is erected on the body, and a support shaft 15 is rotatably supported near the top of the support 13, and an arm rod 14 is loosely fitted on the support shaft 15. At one end (upper side in FIG. 3) of the support shaft 15, a transmission gear 16 that is drivingly connected to a drive unit (not shown) is attached. Reference numeral 17 denotes a case body, and reference numeral 18 denotes a bearing.

A cylindrical body 19 is loosely fitted in the cylindrical body 19, a pulley 20 is fixed to one end (upper side in FIG. 3) of the cylindrical body 19, and a flanged cylindrical body 23 is fixed to the other end (lower side in FIG. 3). Have been. On the other hand, the other end of the support shaft 15
A threaded rod 21 on which a ridge 34 is fitted is screwed to the lower side in FIG. 3, and a flanged cylinder 22 is provided on the threaded rod 21 via a key. The part is fitted into the flanged cylinder 23. A friction ring plate 24 is interposed between the flange of the flanged cylinder 22 and the flange of the flanged cylinder 23.
(Flection clutch). A fixed shaft 25 is fitted into the tip of the arm rod 14, and a punching dust take-up roller 12 is loosely fitted to the fixed shaft 25, and the punching dust take-up roller 12 is rotatable with respect to the fixed shaft 25. Is provided. A pulley 31 is fixedly attached to the end (upper side in FIG. 3) of the punched scrap take-up roller 12 at a position corresponding to the pulley 20, and the pulley 31 and the pulley
A belt 32 is suspended from the belt 20.

A support rod 26 projects from the center of the arm rod 14, and a screw rod 27 with a handle 28 is screwed to an end of the support rod 26. Further, one end of a guide rod 29 is attached to the screw rod 27. Loose fit,
The other end of the guide rod 29 is fixedly fixed to the tip of the fixed shaft 25 by a screw rod 30. When the punching waste 4 wound around the punching waste take-up roller 12 has a large diameter, the handle 28 is used to rotate the screw 27 and the screw 30 is turned to remove.
The guide rod 29 slides around the screw rod 27, so that the punched waste take-up roller 12 can be removed from the fixed shaft 25.

The base of the arm rod 14 is not used when not in use.
(Not shown) is attached to a fixed support portion capable of fixedly supporting the.

Reference numeral 35 denotes a support rod for supporting the arm rod 14,
It expands and contracts as the arm rod 14 moves. This expansion and contraction structure may employ any structure such as a cylinder mechanism, and the degree of expansion and contraction is controlled by using, for example, a microcomputer, and the amount of winding of the punching waste 4 on the punching waste take-up roller 12 increases. The support rod 35 is designed to extend. still,
Instead of using the support rod 35, a weight having an appropriate weight may be attached to the base end of the arm rod 14, and the arm rod 14 may be configured to be balanced about the support shaft 15.

In FIG. 2, the rollers disposed in the punching waste delivery path 9 are a stripping roller 8, a guide roller 10, and a guide roller 10 'from below, and the stripping roller 8 and the guide roller 10' are free. The rollers and guide rollers 10 are configured as drive rollers.

If a configuration is adopted in which the punching waste 4 is peeled off from the backing paper 1 only by the driving rotation of the punching waste winding roller 12,
Since there is a distance between the position where the blank 4 is peeled off from the backing 1 and the blank take-up roller 12, the blank 4 often breaks. In this regard, in this embodiment, the guide roller 10 is used.
This problem can be prevented as much as possible because of the drive rotation. Further, since the guide roller 10 is driven and rotated, it is possible to rotate the guide roller 10 at an increased speed , and accordingly,
It is possible to prevent the punching waste 4 from loosening in the punching waste delivery path 9.

Incidentally, since the back surface (adhesive is adhered) of the punched waste 4 comes into contact with the guide roller 10,
It is desirable to form irregularities on the surface of the guide roller 10 so that the blank 4 is easily peeled off from the guide roller 10.

Reference numeral 33 denotes a take-up roller as the product accumulation section 6.

Since the punched waste winding section 5 according to the present embodiment has the above-described configuration, the following operational effects are exhibited.

The tacking paper supply path 7 is controlled by the peeling roller 8.
The punching chips 4 are peeled from the backing paper 1 of the tack paper 3 which is continuously supplied in the step 3, and the punching chips 4 abut against the peeling roller 8, the guide roller 10, and the guide roller 10 'to continuously punch the chip. Wound around the roller 12. Punching
Debris 4 is always stripping roller 8, the guide rollers 10, because it is in contact with the guide roller 10 ', I or Gillet, or kink,
It does not break. Punched waste take-up roller 12
As the punching waste 4 is wound around, the amount of winding around the punching waste take-up roller 12 increases, and as the punching waste 4 becomes larger in diameter, the support rod 35 extends, and the arm rod 14 becomes the support shaft 15. With the fulcrum as a fulcrum, the punched dust take-up roller 12 gradually rises. The winding of the punching waste 4 around the punching waste take-up roller 12 is performed by rotating the guide roller 10 and turning the punching waste take-up roller 12.
However, as the diameter of the blank 4 wound around the blank take-up roller 12 increases, the outer peripheral speed of the blank 4 increases. In this embodiment, the screw 21
By screwing out, the drive transmission to the cylindrical body 19 of the support shaft 15 is deteriorated, and the rotation repetition of the punching dust take-up roller 12 is slowed down,
The tension applied to the blanks 4 can be made as constant as possible, so that the blanks 4 can be reliably prevented from being cut due to an increase in the peripheral speed of the blanks 4.

In this embodiment, the punching waste 4 is wound not only by the rotation of the punching waste take-up roller 12 but also by the rotation of the punching waste take-up roller 12 and the guide roller 10. As a result, the cutout 4 can be prevented from being cut. That is, the punching waste take-up roller 12
If the configuration is such that the punching dust 4 is wound up by only the roller, the diameter of the punching dust take-up roller 12 is variable, so that the control of the rotation speed is complicated. The above problem can be solved by using a driving roller to take up the punching waste 4.

As described above, according to the present embodiment, by appropriately setting the rotation speed of the punching waste take-up roller 12, the punching waste 4 is not cut, and even if the diameter of the punching waste take-up roller 12 becomes large, there is no problem. The punching waste 4 can be wound around the guide roller 12.

It is desirable that the control of the rotation speed of the punching dust take-up roller 12 be performed by a microcomputer or the like.

As described above, according to the present embodiment, it is possible to satisfactorily wind up the punching waste 4 around the punching waste take-up roller 12.

Incidentally, the number of guide rollers 10 , 10 ' is not limited to two as shown, and the lifting and lowering of the punching dust take-up roller 12 is not limited to the illustrated structure. It is also possible to adopt a structure in which the shaft of the punching dust take-up roller 12 is erected on the two guides provided,
The speed control means of the punching waste take-up roller 12 is shown in the drawing.
However , the present invention is not limited to this, and electric control means may be employed.

[0030]

As described above, the present invention has an excellent effect that, since the punching chips are cut, twisted or twisted, the punching chips can be taken up by the punching chip take-up roller satisfactorily. The present invention provides a waste chip winding device in a label printing machine that can be used effectively.
