There is.

The procedure for binding the petiole portion 1B of a plurality of large leaves 1 by the binding device configured as described above will be described. First, as shown in FIG. 1, the adhesive tapes 21 and 31 are drawn out from the left and right tape rolls 2 and 3, respectively, and the adhesive surfaces of the adhesive tapes 21 and 31 are brought into contact with each other at a position where a plurality of large leaves are bound to each other. The bonded tips are held by being sandwiched between the rotating rollers 413 and 413. This work may be performed artificially or automatically using a robot arm. From this state, the screw shaft 10A is moved downward by the operation of the first linear actuator 10 to lower the set of support members 41 and 41 (first vertical movement). As a result, as shown in FIG. 2, the cam mechanism 11 separates a set of support members 41 and 41 to switch to an open state in which the support members 41 and 41 are not supported. In this state, the perilla leaves are stacked one by one on the perilla fixing table 5 using a robot hand or the like until the predetermined number of perilla leaves is reached (or the perilla 1 after stacking the predetermined number of perilla leaves 1 is moved to the perilla fixing table 5 using the robot hand or the like. Place).

After the perilla 1 shown in FIGS. 2 and 3 is placed, the restraint means 8 is moved to the restraint position by the operation of the second linear actuator 13 as shown in FIG. After this movement, the pair of restraining members 81 and 81 are closed by energizing the restraining solenoid 82 to restrain the petiole portion 1B of the perilla 1 (see FIG. 5B). From this state, the first linear actuator 10 is operated to move the screw shaft 10A upward in the opposite direction to the above, thereby raising the set of support members 41 and 41 (second vertical movement). As a result, the petiole portion 1B of the restrained large leaf 1 comes into contact with the tips of the adhesive tapes 21 and 31, the adhesive tapes 21 and 31 are fed downward through the opening 4A, and the adhesive tapes 21 and 31 are pulled out from the petiole portion 1B of the large leaf 1. Wrap around part 1B. From the time when the winding of the adhesive tapes 21 and 31 is completed, the tip end portion of the contact member 112 is gradually disengaged from the contact rotating rollers 111 and 111, so that the pair of rotating rollers 413 and 413 are closed. As a result, the adhesive surfaces of the adhesive tapes 21 and 31 come into contact with each other and are closed (see FIGS. 6 and 7).

After binding, the energization of the restraint solenoid 82 is released, and the restraint of the petiole portion 1B of the perilla 1 by the restraint members 81 and 81 is released. After that, as shown in FIGS. 8 and 9, the cutter solenoid 14B is operated to project the cutter 14A and cut the upper portions of the adhesive tapes 21 and 31 in the closed portion where the adhesive surfaces are in contact with each other. Therefore, the adhesive tapes 21 and 31 on the tape roll side can be separated from the bonded adhesive tapes 21 and 31 while maintaining the state in which the leaf handle portion 1B of the large leaf 1 is bound by the adhesive tapes 21 and 31. After cutting, the second linear actuator 13 is operated to move the restraint means 8 from the restraint position to the standby position (see FIG. 10), and the bundling work is completed. After the binding is completed, the bound large leaf 1 is moved from the large leaf fixing base 5 artificially or by a robot hand and waits so that the next binding work can be performed.

As described above, after the adhesive tapes 21 and 31 are cut by the cutter 14A, the tips of the adhesive tapes 21 and 31 are sandwiched by a pair of rotating rollers 413 and 413 in a state of being adhered to each other. At times, it is possible to eliminate the need for operations such as feeding out the adhesive tapes 21 and 31 to bond the tips to each other, and the bundling operation can be continuously performed, so that the work time can be shortened.
