With the other end of the rotating arm 3542A as a rotating fulcrum 3542C, the link 3542B is swung so that the movable member 351 can be brought closer to or away from the mounting section 33. As shown in FIG.

A procedure for cutting the tape 5 to a predetermined length by the tape cutting mechanism 3 configured as described above will be described. First, from the state shown in FIG. 2, the drive shaft 3542H of the DC motor 3542 is driven to rotate in one direction (counterclockwise), thereby rotating the rotating arm 3542A and rocking the link 3542B. 351 approaches the mounting portion 33 (see FIG. 4). After approaching, by extending the solenoid cylinder 353B, the tape chuck 352 is moved upward to pierce the tape 5 mounted on the mounting portion 33 from below with the needle 352A (see FIG. 5). After the stabbing, the driving shaft 3542H of the DC motor 3542 is driven to rotate in the other direction (clockwise), thereby rotating the rotating arm 3542A and swinging the link 3542B, thereby moving the movable member 351 to the mounting portion. 33 to the original position, and the tape 5 is pulled out to a predetermined length (see FIG. 6). After the tape 5 is pulled out, both ends of the non-adhesive side of the tape 5 are sucked from above by suction pads 41, 41, which will be described later, to maintain the tape 5 in a horizontal posture (see FIG. 7). After the suction, the cutting blade 341 is moved upward by extending the solenoid cylinder 343 to cut the tape 5 (see FIG. 8). After cutting, the cutting blade 341 is moved downward to the original standby position by shortening the solenoid cylinder 343, and the cutting process of the tape 5 is finished (see FIG. 9). Although not shown, by shortening the solenoid cylinder 353B, the tape chuck 352 is also moved to the lower standby position before the binding operation is started.

As shown in FIGS. 10 and 11, the tape binding mechanism 4 has a pair of holding portions that hold the tape 5 in a horizontal posture pulled out to a predetermined position by the tape pull-out portion 35 from the non-adhesive surface side (upper side in this case). suction pads 41, 41, a lifting mechanism 42 for lifting and lowering the suction pads 41, 41, and the tape 5 held by the suction pads 41, 41 is a plurality (for example, 10) of foliar agricultural products (here, perilla 1) gathered. A winding operation unit 43 for winding around the petiole, which is the part to be bound of the group of foliar agricultural products, to wind around the petiole of the group of foliar agricultural products, and the winding operation unit 43 causes the tape 5 to be wrapped around the petiole of the group of foliar agricultural products. An inner diameter adjustment part 44 for adjusting the inner diameter of the ring-shaped part 5A wound around the circumference so as to reduce the inner diameter, and a pressing pad 45 for pressing from the thickness direction the leaf blade part of the group of leaf-like agricultural products in which a plurality of leaf-like agricultural products are stacked. and have.

12, 13A, and 14A are diagrams in which the lifting mechanism 42 is omitted. 13B and 14B, the lifting mechanism 42 is omitted, and members (second swing arms 441, 441, The drawing omits the adjustment bars 44A, 44A, etc.). 14C and 15, the lifting mechanism 42 is omitted and the pressing pad 45 is omitted. 13A and 13B show the same operation, and FIGS. 14A, 14B and 14C show the same operation.

The suction pads 41, 41 are composed of a circular suction portion 41A whose tip is made of synthetic rubber or the like and has a suction port in the center, a pipe group 41B connecting a plurality of pipes to which the suction portion 41A is connected, and a pipe group 41B. and a vacuum pump (not shown) which is supply means for supplying suction air to a hose (not shown) connected to the proximal end of the vacuum pump. The suction pads 41, 41 are configured to hold both ends of the tape 5 in the longitudinal direction. Here, the positions at which the suction pads 41 and 41 hold both ends of the tape 5 are configured to be substantially symmetrical with respect to the center of the tape 5 in the longitudinal direction. Therefore, force is evenly applied to both ends of the tape 5 . Therefore, the tape 5 can be tightly wrapped around the group of agricultural products (here, the group of foliar agricultural products).

As shown in FIG. 10, the lifting mechanism 42 includes a plate-like movable member 421 to which the suction pads 41 and 41 are attached, a crank mechanism 422 for lifting and lowering the movable member 421, and a drive source for driving the crank mechanism 422. a DC motor 423; The crank mechanism 422 includes a rotating arm 422A having one end connected to the drive shaft 423A of the DC motor 423, and a link 422B having one end connected to the other end of the rotating arm 422A. The other end of the link 422B is connected to an operation piece 421A provided on the movable member 421. As shown in FIG. Therefore, by driving and rotating the drive shaft 423A of the DC motor 423 in one direction for a predetermined period of time from the state of FIG. 10, the rotating arm 422A is rotated downward by a predetermined angle. With the other end of the rotating arm 422A as a rotating fulcrum 422b, the link 422B is swung so that the movable member 421 can be lowered. At the position where the movable member 421 is lowered, as shown in FIG. 7, the suction pads 41, 41 contact both ends of the tape 5 from above to suck them. When the tape 5 is cut to a predetermined length after being sucked, the moving mechanism Z (see FIG. 1) moves above the leaf blade portion 1A (see FIG. 10) of the group of leaf-like agricultural products in which a plurality of leaf-like agricultural products are stacked. After this movement, the drive shaft 423A of the DC motor 423 is driven to rotate in one direction for a predetermined period of time, thereby rotating the rotating arm 422A further downward by a predetermined angle. By this rotation, the pressing pad 45 contacts and presses the leaf blade portion 1A (see FIG. 1) of the leaf-like agricultural product group in which a plurality of leaf-like agricultural products are piled up from the thickness direction (here, from above) (in FIG. 12, the leaf blade portion Although 1A is omitted, the leaf blade portion 1A is pressed). After the binding process, which will be described later, is completed, the drive shaft 423A of the DC motor 423 is driven to rotate in the other direction to raise the movable member 421 to a predetermined position, and the next tape cutting operation is performed to perform the binding operation. become.

The revolving motion part 43 is mounted at the lower end of the movable member 421 and substantially at the center in the left-right width direction so as to be capable of swinging about the respective axes X1 and X2 provided at one end in a state where the ends are butted against each other in a horizontal posture. a pair of left and right first rocking arms 431, 431, plate-like connecting arms 432, 432 connecting the first rocking arms 431, 431 and the pipe groups 41B, 41B, and longitudinal lengths of the connecting arms 432, 432 An inverted T-shaped elevating member 433 that is connected to the direction intermediate portion and is movable in the vertical direction, a solenoid cylinder 434 that serves as a drive source for elevating the elevating member 433, and a rod 434A of the elevating member 433 and the solenoid cylinder 434. and a plate-like connecting member 435 that connects. Therefore, since the revolving operation part 43 revolves and winds the tape 5 held by the suction pads 41, 41 around the part to be bound of the group of agricultural products, a structure for pressing the agricultural products is not required. Therefore, it can bind without damaging agricultural products.

The pressing pad 45 is generally L-shaped in a side view and has a vertical plate portion 45A and a horizontal plate portion 45B that is bent 90 degrees so as to extend forward from the lower end of the vertical plate portion 45A. An upper end portion of the vertical plate portion 45A is fixed to a bracket 351R fixed to the movable member 351. As shown in FIG. Therefore, when the movable member 351 is positioned at the lowered position, the horizontal plate portion 45B of the pressing pad 45 can contact and press the leaf blade portion 1A of the group of leafy agricultural products from above (see FIG. 12). By pressing the leaf blade portion 1A of the foliar agricultural product group with the pressing pad 45 in this way, the leaf blade portion 1A does not jump up when the tape 5 is wound, and the petiole portion 1B does not come loose. The winding of the tape 5 around 1B can be performed satisfactorily.

In front of the pair of left and right first swing arms 431, 431, second swing arms 441, 441 swinging about the same axes X1, X2 as the axes X1, X2 of the first swing arms 431, 431 are provided. I have. Similar to the first swing arms 431 and 431, these second swing arms 441 and 441 swing about respective axes X1 and X2 provided at one end in a state where one ends are butted against each other in a horizontal posture. . A pair of adjustment bars 44A, 44A constituting the inner diameter adjusting portion 44 are attached to substantially the center of the horizontal posture of the second swing arms 441, 441 in the arm length direction. , 441 are formed with cutouts 441K, 441K for sandwiching the connecting arms 432, 432 from the upper and lower centers of the ends of the arms 441 to approximately the center in the arm length direction.

In addition, the second swing arms 441, 441 are connected to the lower ends of plate-shaped vertically elongated members 442 that are attached so as to be vertically movable. One end of an operating member 445 for vertically moving the vertically long member 442 is connected to the upper end of the vertically long member 442 via a relay member 443 . A rod 444A of a solenoid cylinder 444 is connected to the other end of the operating member 445 as a drive source for moving the operating member 445 up and down.

The second swing arms 441 , 441 , the vertically elongated member 442 , the relay member 443 , the solenoid cylinder 444 , and the operating member 445 constitute an inner diameter adjusting mechanism for operating the inner diameter adjusting portion 44 . By operating the inner diameter adjusting unit 44 so that the inner diameter of the ring-shaped portion 5A of the tape 5 is reduced by this inner diameter adjusting mechanism, the play (gap) between the group of agricultural products and the ring-shaped portion 5A of the tape 5 can be reduced. can. 14A, 14B, and 14C, the inner diameter of the annular portion 5A is reduced as shown in FIG. Therefore, it is possible to prevent the wound tape 5 from coming off the bound part of the group of agricultural products.

A procedure for binding the petiole portions 1B of a plurality of large leaves 1 (here, 10, but any number of them) by the tape binding mechanism 4 configured as described above will be described. As described above, the movable member 421 is lowered by the lifting mechanism 42, and the tape is cut to a predetermined length while the tape 5 is held by the suction pads 41,41. After that, the binding device 4 is horizontally moved by the moving mechanism Z so that the suction pads 41, 41 holding the tape 5 of a predetermined length are positioned at the position of the group of leaf-like agricultural products to be bound. After the movement, the movable member 42 is further lowered while the horizontal tape 5 sucked by the suction pads 41, 41 maintains its posture, and the horizontal plate portion 45B of the pressing pad 45 moves the leaf blades of the leaf-like agricultural products. The leaf blade portion 1A is pressed from above (in FIG. 12, the leaf blade portion 1A is not shown, but the leaf blade portion 1A is in contact from above). At the same time, the central portion 5S of the tape 5 in the longitudinal direction comes into contact with one radial end of the petiole portion 1B of the group of agricultural products (see FIG. 12). In this state, by shortening the rod 434A of the solenoid cylinder 434, the first swing arms 431, 431 swing downward as shown in FIG. The movement also causes the second swing arms 441, 441 to swing downward (see FIG. 13B). Due to this swinging, both ends 5L and 5R of the tape 5 held by the suction pads 41 and 41 approach the plurality of agricultural product groups in an arcuate trajectory that approaches radially outside the other radial end of the petiole 1B of the agricultural product group. (See loci from FIGS. 13A and 13B to FIGS. 14A, 14B and 14C). Since the tape 5 is wound around the petiole part 1B of the group of agricultural products in this way, the group of agricultural products can be bound with the tape 5 having an inner diameter larger than the outer diameter of the petiole part 1B of the group of agricultural products. Therefore, the tape 5 can be loosely wrapped around the petiole portion 1B of the group of agricultural products (see FIG. 14A). As described above, since the placement portion 21 of the support base 2 is inclined downward toward the vertical plate portion 22, the leaf blade portion 1A is positioned higher than the petiole portion 1B. Therefore, the lower surface of the horizontal plate portion 45B of the pressing pad 45 is positioned above the tips of the suction pads 41,41. Therefore, the horizontal plate portion 45B of the pressing pad 45 abuts the leaf blade portion 1A of the foliage plant from above, and at the same time, the longitudinal central portion 5S of the tape 5 abuts one radial end of the petiole portion 1B of the foliage plant. be able to.

After winding, the adhesive surfaces of both ends 5L and 5R of the tape 5 are brought into contact with each other so that both ends of the tape 5 are closed to form a loop (see FIGS. 14A to 14C). At the same time, the pair of adjusting bars 44A, 44A also swings downward while drawing an arc-shaped locus, and the pair of adjusting bars 44A, 44A approach each other and move both ends of the tape 5 above the suction pads 41, 41. The adhesive surfaces of the portions 5L and 5R are brought into contact with each other while facing each other (see FIGS. 14A and 14C). Thereafter, the rod 444A of the solenoid cylinder 444 is contracted to raise the vertically elongated member 442. As shown in FIG. At this time, since the notches 441K, 441K of the second swing arms 441, 441 are open downward, the second swing arms 441, 441 can be lifted, and the second swing arms 441, 441 A pair of attached adjustment bars 44A, 44A are also raised. As a result, the inner diameter of the ring-shaped portion 5A can be adjusted (reduced) (see FIG. 15).
