Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tape sticking device in a winder device. More specifically, the present invention relates to a tape sticking device for sticking an adhesive tape for bonding a web to be wound to a core used as a winding core when winding a web of newspaper or the like with a winder device. 2. Description of the Related Art A conventional winder device and a tape attaching mechanism will be described with reference to FIGS. A winder device is a device that cuts a manufactured web into a predetermined width by a slitter and then winds the web to a predetermined width.
The apparatus includes a pair of winder drums 101 and 102, a core loading device 103, and a tape sticking mechanism 104. When winding the web, first, an adhesive tape is attached to the core C supported by the core loading device 103 by the tape attaching mechanism 104, and the core loading device 103 is turned to rotate the core between the pair of winder drums 101 and 102. C is positioned, and then the winder drums 101 and 102 are rotated while the web is adhered to the adhesive tape on the core C and pressed by a riding roll (not shown). This winder drum 10
Due to the rotation of 1,102, the core C rotates while winding the web, and finally the web is finished into a winding roll R indicated by an imaginary line. As the core C used in the winder device as described above, several cores having a length corresponding to the width of the web slitter are used at the same time.
As shown in FIG. 6, is configured to be able to travel so that the tape can be adhered to several cores C arranged in the length direction. That is, the tape applying mechanism 104 has a traveling mechanism including the chain 107 wound around the sprockets 105 and 106 and the drive motor 108, so that the tape applying apparatus 100 can travel. [0003] The basic configuration of a conventional tape sticking apparatus 100 will be described with reference to FIG. Reference numeral 1 denotes a parent winding tape reel on which a double-sided tape T is wound. The double-sided tape T is a known adhesive tape including a band-shaped adhesive material Ta and a mount Tb stuck on the adhesive material Ta. Reference numeral 2 denotes a mount take-up reel for winding the mount Tb peeled off from the adhesive material Ta stuck on the core C. Reference numeral 3 denotes a pressing roller, which is a double-sided tape T fed from the parent reel 1.
Is pressed onto the web winding core C to adhere the adhesive Ta. A drive pulley 4 is connected to the mount take-up reel 2, and a belt 5 is connected to the drive pulley 4.
With this, it is connected to the pressing roller 3 and rotates in conjunction with it. And, usually, the mount take-up reel 2 is designed so that the take-up speed of the mount Tb is faster than the pay-out speed of the double-sided tape T so as not to cause irregular winding. [0004] However, in the case of the above-described conventional apparatus, when the winding diameter of the mount Tb is increased, the mount Tb is increased.
, The winding speed is increased, and an excessive tension is applied to the mount Tb to cut the mount. In view of such circumstances, an object of the present invention is to provide a tape attaching device that does not cut a mount. SUMMARY OF THE INVENTION The present invention is directed to a parent winding tape reel in which a double-sided tape in which a backing sheet is adhered to a band-shaped adhesive material is wound, and a double-sided tape reeled out from the parent winding tape reel is web-wrapped. A pressing roller that presses the adhesive onto the take-up core, and a mount take-up reel that winds the mount separated from the adhesive applied on the core; and What is claimed is: 1. A tape application device comprising a tape application magazine comprising a drive pulley for transmitting a rotating torque to a mount take-up reel, wherein the drive pulley and the mount take-up reel are connected via a sliding torque limiter. The upper limit of the transmission torque of the torque limiter is set to a value not exceeding the cutting tension of the backing sheet. According to the present invention, the winding diameter of the backing material wound on the backing take-up reel is increased, the winding speed of the backing material is increased, and the rotational torque due to the backing paper tension is reduced by the set transmission torque of the torque limiter. when beyond the will, trickle limiter is slipping
As a result , excessive drive torque is not transmitted from the drive pulley to the mount winding reel, so that the mount is not cut. Next, an embodiment of the present invention will be described with reference to the drawings. The tape application device shown in FIGS. 1 and 2 includes a tape application magazine 10, a traveling platform 20, and a tape application magazine 10.
And an operation mechanism 30 for swinging the. The tape-attached magazine 10 includes a master winding tape reel 1, a mount winding reel 2, and a pressing roller 3 attached to a plate 11, and further includes a guide roller 12 and a tension roller 13. The main winding tape reel 1 is provided with a lock mechanism 14 for preventing rotation during tape cutting. The lock mechanism 14 is a known mechanism including a gear fixed to the master winding tape reel 1, a claw, and a cylinder for pushing the claw. Press roller 3
, A pulley 15 is fixed coaxially, and a drive pulley 4 is also fixed coaxially to the mount take-up reel 2, and a toothed belt 5 is looped between the two. For this reason,
The driving pulley 4 rotates in conjunction with the pressing roller 3, and the rotational torque of the driving pulley 4 is transmitted to the mount winding reel 2,
The mount winding reel 2 is rotated. A torque limiter 40 described later is interposed between the drive pulley 4 and the mount take-up reel 2. The traveling platform 20 comprises a platform 21 and the platform 2
1, a traveling guide rail 25 and a guide member 2 arranged in parallel with the core loading device 103 (see FIG. 5).
6 guides traveling. Also, a chain 107 for traveling drive (FIG. 6) is attached to the lower end bracket 27 of the gantry 21.
See). The operating mechanism 30 includes a pair of links 31 and 32 pivotally mounted between the plate 11 of the tape-attached magazine 10 and the gantry 21 of the traveling gantry 20.
And an air cylinder 33 interposed between the frame 21 and the base 21. When the air cylinder 33 is extended, the links 31 and 32 stand vertically as shown in FIG. 1, the tape-attached magazine 10 is at the upper position, and when the air cylinder 33 is contracted, the tape-attached magazine 10 is lowered as shown in FIG. Then, the pressing roller 3 comes into contact with the core C. In the state shown in FIG. 3, the double-sided tape T fed from the parent winding tape reel 1 is pressed against the core C by the pressing roller 3 and the traveling base 20 is run, so that the adhesive T
a is adhered on the core C, the mount Tb is peeled off from the adhesive material Ta, and is wound up on the mount take-up reel 2 via the master winding tape reel 1. When the adhesion of the adhesive Ta is completed, the air cylinder 33 is extended (arrow P), and the tape-attached magazine 10 is moved to the upper position as shown in FIG. At this time, the double-sided tape T is torn off immediately below the pressing roller 3, and the bonding operation is completed. Next, the details of the torque limiter 40 will be described. As shown in FIG. 4, the main body 41 of the torque limiter 40 is
Fixed at 2. Reference numeral 16 denotes a cover. The main body 41 of the torque limiter 40 is a thick-walled cylindrical member, and its outer periphery is taped through a bearing 51 via a tape-attached magazine 10.
Is rotatably supported by the plate 11. A bearing 52 is fitted into the internal cavity 43 of the main body 41, and the support shaft 6 of the drive pulley 4 is inserted and fixed therein. Several cylindrical cavities 44 are formed axially symmetrically in the thick portion of the torque limiter main body 41, and a washer 45, a spring 46, and a friction body 47 are formed in each of the cavities 44.
Is inserted, and the friction body 47 is attached to the inner side wall 4 of the drive pulley 4.
a. The frictional force between the friction body 47 and the side wall 4a of the drive pulley 4 is generated by the urging force of the spring 46. In a normal operation state, the rotational torque of the drive pulley 4 is transmitted to the mount take-up reel 2 by the frictional force, and the drive pulley 4 and the mount take-up reel 2, which are interlocked and rotated by the pressing roller 3, rotate together. However, as shown in FIG. 3, the winding diameter d of the backing sheet Tb increases, and the winding speed of the backing sheet Tb becomes faster than the feeding speed of the double-sided tape T from the parent winding tape reel 1, so that the rotation torque due to the backing sheet tension is reduced. When the torque exceeds the set transmission torque of the torque limiter, a slip occurs between the friction body 47 and the side wall 4a of the driving pulley 4, and the rotation torque is not transmitted to the mount winding reel 2. For this reason, excessive tension is not applied to the mount Tb, and the cut of the mount Tb is prevented. In the above embodiment, a friction plate slip clutch type is used as the sliding type torque limiter. Instead, any type of torque limiter such as a magnetic clutch or an electromagnetic friction type clutch can be used. . According to the present invention, when the double-sided tape is applied to the web winding core, it is prevented from being cut without applying excessive tension to the backing paper, and the web is wound with an appropriate torque.
Ru can continue. Therefore, the tape attaching operation can be performed efficiently.
