A clamp 140 and a feed wheel 130 provided with a clamp 140 and rotatably fixed to the driven gear 124 are provided to pick up the tag 31 and transfer it onto the fabric. The conveying wheel 130 is coupled to the driven gear 124 so that the driven gear 124 rotates together when it rotates and stops when it stops. Thus, the driven wheel 124 performs an intermittently rotating motion like the driven gear 124. The shape of the conveying wheel 130 is not limited, but is preferably a circular disc shape. A clamp 140 is installed on the feed wheel 130 at a predetermined interval such that an angle with the center of the feed wheel 130 is constant. The clamp 140 is coupled to the coupling groove 132 formed at the lower portion of the transfer wheel 130. A thread support protrusion 131 is formed around the transfer wheel 130 at regular intervals. As shown in FIGS. 3 and 4, the yarn supporting portion 131 supports the yarn so that the yarn between the tag and the tag picked up by the clamp 140 forms a curved line. The front end of the clamp 140 for holding the tag, that is, the clamping portion 142 is coupled to the outside of the conveying wheel 130 by a predetermined length, and the clamp 140 is opened / The rear end portion, that is, the actuating portion 141 is partially inserted into the coupling groove 132, and a portion thereof is installed to be exposed downwardly of the conveying wheel 130. The operating part exposed downward is opened and closed by passing through the clamp driving pin 151 of the clamp driving part 150 provided at the lower adjacent position of the conveying wheel 130.

As shown in FIGS. 1 and 5, a clamp driving unit is installed at a position adjacent to the lower portion of the conveying wheel 130. The clamp driving part 150 includes a pin fixing part 152 to which the clamp driving pin 151 and the clamp driving pin 151 are fixedly coupled. The pin fixing portion 152 is fixed so as not to rotate, and a pair of clamp driving pins 151 are provided at an upper portion of the pin fixing portion 152. The tip of the clamp drive pin 151 is tapered so that the actuating portion 141 of the clamp 140 exposed below the feed wheel 130 smoothly passes through the clamp drive pin 152. [

1, a tea bag tag attaching apparatus according to the present invention includes the above-described rotary type tea bag transfer apparatus and includes an ultrasonic welder 230 (FIG. 1) for welding the tag units 31 and 32 transferred onto the fabric 20 to the fabric, A cutter 220 for cutting the yarn in units of tag units, and a conveying roller 210 for conveying the fabric to which the tag unit is coupled. When the tag unit is transported onto the fabric by the rotary type tea bag transfer device, welding by the ultrasonic welder 230 and cutting by the cutter 220 are performed.

The operation principle of the rotary type tea bag transfer device and the tea bag tag attachment device including the rotary type tea bag transfer device according to the present invention will be described. When the drive motor 110 rotates, the feed wheel 130 intermittently rotates together with the driven gear 124 of the Geneva gear 120 driven by the drive motor 110. The tag is gripped by the clamp 140 as shown in Fig. As the feed wheel 130 rotates, the clamp 140 is pressed by the clamp driving pin 151 provided below the clamp driving pin 151. When the clamp 140 is opened and the clamp 140 The tag is inserted between the clamping portions 142 of the clamping portions 142. [ When the conveying wheel 130 further rotates, the operation portion of the clamp 140 is disengaged from the clamp driving pin 151, so that the clamping portion 142 is closed and the tag 31 is gripped. When the conveying wheel 130 is rotated while the tag 31 is being held, the tag is held by the clamp 140 and the yarn 32 is supported by the yarn supporting protrusions 131, . The rotary motion of the feed wheel 130 is stopped while the tag unit is positioned on the fabric and the clamp 140 is opened by the drive pin 123 to release the tag and the ultrasonic welder (230) is actuated to weld the tag unit to the fabric (20) and cut by the cutter (220). Since the tag unit attached on the fabric 20 forms a curve as shown in FIG. 4, a separate blowing process is not necessary. The conveying wheel 130 starts rotating again, the fabric 20 is conveyed by the conveying roller 210, and the process of conveying, welding and cutting the tag unit again on the conveyed fabric is repeated. The feed roller 210 is interlocked with the intermittent pivoting device. The conveying wheel 130 rotates in conjunction with rotation and stops when the conveying wheel 130 stops. After the tag unit is attached to the fabric, the fabric is cut to a certain length and used in the manufacture of tea bags, especially triangular pyramid tea bags.
