Abstract

<P>PROBLEM TO BE SOLVED: To provide a winding device, capable of preventing inverse rotation of a winding drive shaft even in a case where winding tension is becoming lower due to larger winding diameter of the strip of backing paper so as to eliminate generation of loosening in the strip of backing paper. <P>SOLUTION: The winding drive shaft 11 is pivotally supported through a one-way hinge 15 to a support plate 211 that is fixed to a main body frame. The one-way hinge 15 is provided with functions of a one-way clutch and a torque limiter. For rotation of the winding drive shaft 11 in the winding direction, it is idly rotated without generating torque. For rotation in the inverse direction to the winding direction of the winding drive shaft 11, torque is generated. In a case where the winding drive shaft 11 is stopped synchronously with a transfer roller of a transfer part, rotation of the winding drive shaft 11 inversely to the winding direction is thus prevented. <P>COPYRIGHT: (C)2006,JPO&NCIPI

Description

  The present invention relates to a winding device for winding a belt-like mount, and more particularly, to a label sticking device that peels off a label temporarily attached to a belt-like mount and sticks it to an adherend, and winds the belt-like mount from which the label is peeled off. The present invention relates to a take-up device.

  For label affixing devices that peel off the label temporarily attached to the belt-like mount and attach it to the adherend, a plurality of labels are temporarily attached to the belt-like backing at intervals in order to feed out the label to be attached to the adherend. However, the transfer means and the take-up device are driven by the same drive source. In many cases, the winding operation of the winding device is also stopped in synchronization with the stop of the transfer of the label continuum by the transfer means (see, for example, Patent Document 1).

However, in the conventional technique, the winding operation of the winding device is also stopped in synchronization with the stop of the transfer of the label continuous body by the transfer means, so that the winding diameter of the belt-like mount becomes large and the tension for winding is weakened. In this case, the take-up drive shaft rotates in the opposite direction due to tension applying means that reduces the influence of the take-up force, causing the band mount to become slack, and the belt mount is wound up. In addition, there was a problem that it was impossible to wind.

  The label sticking device 2 is a device that is arranged above the conveyor 5 and peels off the label 3 temporarily attached to the belt-like mount 4 and sticks it to the adherend 6 conveyed on the conveyor 5. Referring to FIGS. 1 and 2, a label supply unit 22 is provided on the upper portion of the main body frame 21. The label supply unit 22 includes a supply reel 221 that is mounted in a state in which a label continuous body 7 on which a plurality of labels 3 are temporarily attached to the belt-like mount 4 is wound in a roll shape, and the supply reel 221. The label continuous body 7 which is composed of guide plates 222 and 223 for respectively guiding both end surfaces of the attached label continuous body 7 and is wound in a roll shape is rotatably held on the supply reel 221.

  The label continuous body 7 fed out from the supply reel 221 passes through the upper surface side of the transfer unit 23 and is transferred to the peeling plate 24. Reference numeral 25 shown in FIGS. 1 and 2 is a tension roller that absorbs a change in tension applied to the label continuum 7, and is arranged in the transfer path from the supply reel 221 to the transfer unit 23.

  The release plate 24 has a tip formed at an acute angle, turns the belt-like mount 4, and the label 3 having a higher rigidity than the belt-like mount 4 is peeled off from the belt-like mount 4 and fed forward. The label 3 fed out from the peeling plate 24 is pressed against the upper surface of the adherend 6 conveyed by the conveyor 5 by a sticking roller 26 provided in front of the peeling plate 24 in the label feeding direction. It is affixed at a predetermined position on the upper surface.

  Further, a label detection sensor 27 for detecting the leading end of the label 3 is arranged on the upstream side of the peeling plate 24 in the transport direction of the label continuum 7, and by grasping the leading end of the label 3 by the label detection sensor 27, Control is performed so that the tip of the label 3 fed out from the peeling plate 24 is stuck to a predetermined position on the upper surface of the adherend 6.

  On the other hand, the strip-shaped mount 4 from which the label 3 has been peeled is transferred to the winding device 1 through the lower surface side of the transfer unit 23 and wound. Reference numeral 28 shown in FIGS. 1 and 2 is a tension roller that absorbs a change in tension applied to the belt-like mount 4, and is arranged in the transfer path from the transfer unit 23 to the winding device 1.

  The transfer unit 23 includes a transfer roller 231 that is rotationally driven by a drive motor (not shown), a first nip roller 232, and a second nip roller 233, and is nipped and transferred by the transfer roller 231 and the first nip roller 232.

Transport.

  Referring to FIG. 3, the winding device 1 is configured to wind the belt-like mount 4 turned by the peeling plate 24 onto the winding reel 12 protruding from the winding device support frame 211 that protrudes from the main body frame 21. ing. 3 is a guide plate that guides the winding of the belt-like mount 4 onto the take-up reel 12, and the guide plate 13 is rotated integrally with the take-up reel 12.

  Referring to FIG. 4, the take-up reel 12 is mounted on the take-up drive shaft 11 and is configured to rotate integrally with the take-up drive shaft 11. The take-up drive shaft 11 includes the bearings 14 a and 14 a. 14b, a one-way hinge that is pivotally supported by the winding device support frame 211 and the support plate 212 (fixed to the winding device support frame 211) and fixed to the support plate 212. 15 is inserted.

  The take-up drive shaft 11 is rotationally driven using a drive motor (not shown) that drives the transfer roller 231 of the transfer unit 23 as a drive source, and the rotational drive force from the drive motor is taken up via the gear 16 and the gear 17. 11 is transmitted to the final gear 18 mounted on the winding 11, and the winding drive shaft 11 is rotationally driven via the torque limiter 19 mounted on the winding drive shaft 11.

  The one-way hinge 15 is a hinge that functions as a one-way clutch and a torque limiter. When the take-up drive shaft 11 rotates in the take-up direction, the one-way hinge 15 is idled without generating torque. Torque is generated in the rotation in the direction opposite to the taking direction. Accordingly, the one-way hinge 15 functions as a means for preventing reverse rotation of the take-up drive shaft 11, and when the take-up drive shaft 11 stops in synchronization with the transfer roller 231 of the transfer unit 23, the take-up drive shaft 11 takes up.

By providing the one-way hinge 15 that prevents the rotation of the belt-shaped mount 4, the winding drive shaft 11 is prevented from rotating in the reverse direction even when the winding diameter of the belt-like mount 4 is increased and the tension for winding is weakened. This is advantageous in that no slack is generated in the belt-like mount 4.

  Further, according to the present embodiment, the one-way hinge 15 is configured to prevent the winding drive shaft 11 from rotating in the direction opposite to the winding direction, so that when the label winding set is performed, the winding is performed. Since the drive shaft 11 (take-up reel 12) can be manually rotated in both forward and reverse directions, there is an effect that the operability is not adversely affected.

  In the present embodiment, the one-way hinge 15 is configured to prevent the winding drive shaft 11 from rotating in the direction opposite to the winding direction. However, instead of the one-way hinge 15, the winding drive shaft 11 is wound. For rotation in the take-up direction, a one-way clutch that is in an idle state and prohibits rotation in the reverse direction with respect to the take-up direction of the take-up drive shaft 11 is used. You may make it prevent rotation.
