[Control Unit] (See FIGS. 1 and 2)
Although not shown, the control unit has at least the following functions. The cutter drive motor 63 is continuously driven when the burdock 1 is fed by a constant amount (length of the randomly cut product) by the continuous drive of the conveyor feed motor 16 and the burdock 1 is rotated 90 degrees by the continuous drive of the rotary drive motor 54. Thus, the cutter 61 is controlled by the control unit to rotate once. Thereby, a random cut product is manufactured.

  The length L1 of the thick part 1c of the burdock 1 and the length L2 of the detail 1e shown in FIG. 10 are stored in advance in the control unit. In the calculation unit of the control unit, the uniform part 1a random cut length, that is, the rotation speed of the conveyor drive motor 16, is set in advance, and the thick part 1c is thicker than the uniform part 1a, and thus is shorter than the uniform cut length of the uniform part 1a. Is set. Since the detail 1e is thinner than the uniform portion 1a, it is set to a length longer than the random cut length of the uniform portion 1a.

  When the proximity sensor 73 detects the rear end of the burdock 1, the length from the rear end of the burdock 1 to the front end detection sensor 74 is a known value. Therefore, when the proximity sensor 73 detects the rear end of the burdock 1 at the cutting position 1f shown in FIG. 10, the length L2 of the detail 1e is subtracted from the length L3 from the cutting position 1f to 1g. The length L4 is the remaining length of the uniform portion 1a. The length L4 is calculated by the calculation unit of the control unit. When the rotary drive motor 54 shown in FIG. 7 is driven, the belt 44 operates to feed the burdock 1 slightly. The reason for this will be described later. Therefore, the calculation unit of the control unit calculates the rotational speed of the conveyor feed motor 16 of the burdock feed unit 10 so as to be driven by correcting the feed length of the burdock 1 by the rotation drive motor 54.

  First, the operation of the conveyor drive motor 16 and the rotation drive motor 54 will be described.

  When the conveyor drive motor 16 is driven, the conveyor drive gear 15 rotates in the arrow B direction together with the output shaft of the conveyor drive motor 16 as shown in FIG. When the conveyor drive gear 15 rotates in the direction of arrow B, the conveyor transmission gear 13B rotates in the direction of arrow C via the conveyor transmission gear 13A and the column 14. Since the transmission gear 26 meshes with the conveyor transmission gear 13B, the transmission gear 26, the transmission shaft 27, and the bevel gear 30 rotate in the arrow D direction. The rotation of the bevel gear 30 is changed in the horizontal direction by the bevel gear 31 and the drive pulley 33 rotates in the direction of arrow E. Thereby, the outer side of the burdock cutting part 60 moves in the direction of arrow F (upward direction), and the inner side of the belt 44 moves in the downward direction. Therefore, the burdock 1 inserted into the burdock insertion cylinder 11 is gripped by the three belts 44 and sent downward. Therefore, the length cut by the cutter 61 can be changed by changing the rotation speed of the conveyor drive motor 16.

  When the rotation drive motor 54 is driven, the rotation drive gear 53 rotates in the arrow G direction together with the output shaft of the rotation drive motor 54, and the rotation transmission gear 51 rotates in the arrow H direction, as shown in FIG. The rotation transmission gear 51 and the support plate 18 </ b> A are integrally coupled by a column 52, and the support plate 18 </ b> A and the support plate 18 </ b> B are integrally coupled by a column 19. Thereby, when the rotation transmission gear 51 is rotated in the direction of arrow H, the support plate 18B and the three conveyors 25 are also rotated in the direction of arrow H. That is, the burdock 1 gripped by the conveyor 25 is rotated. In this case, since the transmission shaft 27 is rotatably provided on the support plate 18B as shown in FIG. 6, when the support plate 18B rotates, the transmission shaft 27 slightly rotates in the direction of arrow D. When the transmission shaft 27 rotates in the direction of arrow D, the belt 44 moves in the direction of feeding the burdock 1 as described in the operation of the conveyor drive motor 16 according to the rotation amount. The calculation unit of the control unit corrects the feed amount and calculates the rotational speed of the burdock feed unit 10. Therefore, the cutting direction can be changed by changing the rotation speed of the rotation drive motor 54.

  Next, the operation will be described. When a start button (not shown) is pressed, the conveyor drive motor 16, the rotation drive motor 54, and the cutter drive motor 63 rotate. In this case, as shown by the two-dot chain line, the distribution plate 85 shown in FIG. 1 guides the first cut piece cut by the cutter 61 from the introduction portion 81a to the defective product chute 81c. When the burdock 1 is inserted into the burdock insertion cylinder 11, the rear end detection plate 72 is rotated from the solid line state to the two-dot chain line state. Thereby, the rear end detection plate 72 is separated from the proximity sensor 73, and the proximity sensor 73 is turned off.

  As explained in the operation of the conveyor drive motor 16 and the rotation drive motor 54 described above, when the conveyor drive motor 16 is operated, the belt 44 moves in the direction of arrow F, that is, in the direction of sending the burdock 1 downward. When the rotation drive motor 54 is operated, the three conveyors 25 rotate in the direction of arrow H as shown in FIG. Therefore, the burdock 1 inserted into the burdock insertion cylinder 11 is sent downward. Then, the tip detection sensor 74 detects (turns on) the tip of the burdock 1. Since the cutting portion of the tip detection sensor 74 and the burdock cutting unit 60 by the cutter 61 is constant, the chute 81 is driven so that the non-defective chute 81b is opened based on the feed rate of the burdock 1 at the moment when the tip detection sensor 74 is turned on. Timing is calculated by the control unit. The burdock 1 is sent downward by a preset value set in a control unit (not shown), is rotated 90 degrees by the rotation drive motor 54 of the burdock rotation unit 50, and is inclined by 45 degrees by the cutter 61 of the burdock cutting unit 60 and cut. Is done. In this case, since the first (lower end) cut product is not a defective product but a defective product, when it falls to the introduction part 81a of the chute 81, it is stored in a defective box (not shown) through the defective product chute 81c. That is, the cut product at the lower end is processed as a defective product, not a random product.

  When the first cut product passes the defective product chute 81c, the cylinder 87 is operated at the timing described above, and the distribution plate 85 rotates as indicated by the dotted line, the defective product chute 81c side is closed, and the good product chute 81b side is opened. . Thus, the second and subsequent cut products are stored in the non-defective box through the non-defective chute 81b. When the non-defective cutting operation is repeated and the rear end of the burdock 1 passes the rear end detection plate 72, the rear end detection plate 72 rotates as indicated by the solid line, and the detection unit 72b approaches the proximity sensor 73. Thereby, the rear end of the burdock 1 is detected. The length L3 from the rear end of the burdock 1 to the front end detection sensor 74 when the rear end of the burdock 1 is detected (turned on) by the proximity sensor is a known value. Therefore, the calculation unit of the control unit calculates whether or not there are two or less cut products from the rear end position of the burdock 1, and if the cutter 61 cuts the burdock 1 and the remaining is less than two, the cut product is rejected. It outputs so that it may distribute to non-defective chute 81c. That is, the operating rod of the cylinder 87 is retracted, and the distribution plate 85 rotates so that the remaining portion is guided from the introduction portion 81a to the defective chute 81c as indicated by a two-dot chain line.

  In the present embodiment, the random cutting operation is performed only by the operation of inserting the burdock 1 into the burdock insertion cylinder 11, so that productivity is improved. Moreover, the cutting direction of the burdock can be changed by rotating the gripping part that holds and feeds the burdock, and the speed is increased because the heavy cutter is not rotated, which also improves productivity. Moreover, since the burdock holding part is disposed immediately above the cutter 61 and is cut in order, the burdock can be processed without waste. In addition, since the first (front end) cut product and the rear end cut product of the burdock 1 are processed as defective products, the quality of the product can be made uniform.

  In the above-described embodiment, the cutter 61 is disposed with an inclination of 45 degrees with respect to the axis of the burrow insertion cylinder 11. However, the cutter 61 may be disposed with an inclination in the range of 30 degrees to 60 degrees. Further, the burdock 1 is cut by the cutter 61 when the burdock is driven 90 degrees, but the burdock 1 may be set to be cut when driven by 30 to 120 degrees. Further, the cutter 61 may be a method of linearly moving back and forth with a cylinder instead of a rotating method. Further, although the rear end detection plate 72 is provided as the rear end detection means, a rear end detection sensor may be provided so as to face the vertical groove 11a.
