Each of the part 120c and the fourth elevating part 120d is controlled.

  The operation of the processing apparatus 10 configured as described above will be described below. In the initial state, each of the magnet conveyor 94, the first support portion 118a, the second support portion 118b, the third support portion 118c, and the fourth support portion 118d is located at the lowered position, and the third transport roller 80 is located at the raised position. is doing.

  As shown in FIG. 8A, the workpiece W is loaded into a predetermined position of the cutting device 14 in the workpiece loading step. Specifically, the carry-in roller control unit 140 carries the belt-like workpiece W supplied from the drum 20 into a predetermined position of the cutting device 14 by rotating the carry-in roller 22. At this time, the workpiece W is transferred in the direction of the arrow X1 while being in contact with the first conveyance roller 54, the second conveyance roller 68, and the third conveyance roller 80. Moreover, since the 3rd conveyance roller 80 is located in a raise position, it is suppressed that the workpiece | work W interferes with the lower blade 30. FIG. The carry-in roller control unit 140 stops the rotation of the carry-in roller 22 when the work W is carried into a predetermined position.

  Subsequently, as shown in FIG. 8B, the workpiece W is blanked in the cutting step. That is, the control part 18 lowers the upper mold | type 24 toward the lower mold | type 26 in the state which controlled the movement of the width direction of the workpiece | work W by the workpiece | work regulation mechanism which is not shown in figure. Thereby, the workpiece | work W is cut | disconnected by the lower blade 30 and the upper blade 28, and the 2nd blank P2 is shape | molded.

  At this time, the second conveying roller 68 pushed downward by the workpiece W moves downward while compressing and deforming the urging member 66. Therefore, the second blank P2 is reliably formed. In addition, when the blanking process by the cutting device 14 is the second time or later, the first blank P1 and the second blank P2 are formed. The workpiece end portion Wa (first extension portion 202) of the workpiece W is in the carry-out direction (arrow X1 direction) of the second blank P2 with respect to the second extension portion 302 of the second blank P2 during cutting by the cutting device 14. ).

  The end material generated by the blanking process of the workpiece W falls into the end material discharge hole 112, is cut by a cutting mechanism (not shown), and is then discharged in the arrow Y direction by an end material discharge mechanism (not shown).

  Thereafter, the control unit 18 raises the upper mold 24. At this time, the second transport roller 68 that has moved downward pushes up the second blank P <b> 2 upward by the biasing force of the biasing member 66. Thereby, the height of the second blank P2 is substantially the same as the height of the workpiece W.

  In the carry-out process, the carry-out roller control unit 142 rotates the belt conveyor 32. Thereby, when 1st blank P1 is shape | molded, 1st blank P1 is carried out from the cutting device 14. FIG.

  Subsequently, the elevating control unit 146 includes the first elevating unit 120a, the second elevating unit 120b, and the third elevating unit 120a so that each of the first support unit 118a, the second support unit 118b, and the third support unit 118c is located at the elevated position. Each of the elevating parts 120c is controlled. Thereby, the lower surface of the 2nd extension part 302 of the 2nd blank P2 is pushed up by the 2nd support part 118b. At this time, the second extending portion 302 is separated from the first support portion 118a and the third support portion 118c.

  Moreover, the conveyor control part 144 controls the conveyor raising / lowering part 98 so that the magnet conveyor 94 is located in a raise position. Accordingly, the magnet belt 100 is attracted to the lower surface of the second base 300 of the second blank P2 by the magnetic force. Next, the conveyor control unit 144 operates the motor 96 so that the magnet belt 100 rotates around the first rotating roller 102 and the second rotating roller 104.

  Then, as shown in FIG. 9A, the second blank P2 moves in the arrow X1 direction with respect to the lower mold 26. When the second blank P2 moves in the arrow X1 direction with respect to the lower mold 26, the extended end portion of the second extended portion 302 rides on the third contact portion 126c. That is, a portion of the second extending portion 302 closer to the second base 300 than the extending end portion is supported by the second supporting portion 118b, and the extending end portion of the second extending portion 302 is the third supporting portion 118c. Supported by In this state, the second extending portion 302 is located above the workpiece end portion Wa.

  Subsequently, when the second blank P2 further moves in the direction of the arrow X1 with respect to the lower mold 26, as shown in FIGS. 9B and 10, the corners (in the direction of the arrow X1) of the extending end portion of the second extending portion 302 are obtained. Of the first support portion 118a contacts the inclined surface 134 of the guide portion 122. Then, the extending end portion of the second extending portion 302 is guided onto the first support portion 118a while sliding upward on the inclined surface 134.

  Next, as illustrated in FIG. 11, the second extending portion 302 is separated from the third contact portion 126 c. That is, the third support part 118c is separated from the second extension part 302 in a state where the first support part 118a and the second support part 118b support the second extension part 302 when the second blank P2 is carried out. That is, the first support part 118 a supports the extension end part of the second extension part 302, and the second support part 118 b supports the intermediate part of the second extension part 302 in the extension direction.

  At this time, as shown in FIG. 12A, the second extension portion 302 is positioned so that the lowermost portion of the second extension portion 302 is located above the upper surface of the workpiece end portion Wa in a state of being convexly curved downward. To do. When the second extending portion 302 is curved in this way, the second moment of section of the second extending portion 302 is increased as compared with the case where the second extending portion 302 is not curved.

  Therefore, as shown in FIG. 12B, dripping due to the weight of the second extending portion 302 is suppressed. Therefore, the side part of the 2nd extension part 302 of the arrow X2 direction does not contact the 1st extension part 202. FIG. That is, it is possible to prevent the second extending portion 302 from interfering with the first extending portion 202 of the workpiece W when the second blank P2 is unloaded.

  As shown in FIG. 13A, when the second blank P <b> 2 is transferred to the belt conveyor 32, the second blank P <b> 2 is carried out by the belt conveyor 32. That is, the processing apparatus 10 carries out the second blank P2 so that the second extending portion 302 gets over the workpiece end portion Wa. And the conveyor control part 144 controls the motor 96 so that rotation of the rotating rollers 102 and 104 may be stopped.

  Subsequently, the conveyor control unit 144 controls the conveyor lifting / lowering unit 98 so that the magnet conveyor 94 is positioned at the lowered position. The lift controller 146 also includes the first lift part 120a, the second lift part 120b, and the third lift part so that the first support part 118a, the second support part 118b, and the third support part 118c are positioned at the lowered positions. Each of the units 120c is controlled. Moreover, the raising / lowering control part 146 controls the 4th raising / lowering part 120d so that each 4th support part 118d of the carrying-in support mechanism 116a and the carrying-in support mechanism 116b is located in a raise position.

  Thereafter, as shown in FIG. 13B, in the work carry-in process, the carry-in roller control unit 140 carries the work W into a predetermined position of the cutting device 14 by rotating the carry-in roller 22. Then, the workpiece W moves in the direction of the arrow X1 on the first conveyance roller 54, the second conveyance roller 68, and the third conveyance roller 80.

  Then, the lower surface of the workpiece end portion Wa rides on the fourth support portion 118d of the carry-in support mechanism 116a. In other words, the workpiece end portion Wa is supported by the fourth support portion 118d. This prevents the workpiece end Wa from falling into the end material discharge hole 112.

  As shown in FIG. 14, when the loading of the workpiece W is completed, the above-described cutting step, unloading step, and workpiece loading step are repeatedly executed.

  In this case, the processing apparatus 10 according to the present embodiment has the following effects.

  When the second blank P2 is unloaded, the support device 40 of the lower mold 26 is such that the lowermost portion of the second extending portion 302 is curved in a convex shape toward the lower side, and the lower end of the second extending portion 302 is the workpiece end portion Wa. The lower surface of the second extending portion 302 is supported so as to be positioned above the upper surface of the second extending portion 302.

  Thereby, compared with the case where the 2nd extension part 302 is not curved, the cross-sectional secondary moment of the 2nd extension part 302 can be enlarged. Therefore, since the sagging due to the weight of the second extending portion 302 can be suppressed, the lowermost portion of the second extending portion 302 is surely positioned above the upper surface of the workpiece W when the second blank P2 is carried out. Can do. Therefore, the 2nd blank P2 can be carried out smoothly.

  The support device 40 includes first to third support portions 118a to 118c that support a plurality of portions of the second extension portion 302 when the second blank P2 is carried out. Thereby, the dripping by the dead weight of the 2nd extension part 302 at the time of carrying out the 2nd blank P2 can be suppressed effectively.

  The first support portion 118a includes a first support stand 124a and a plurality of first contact portions 126a that are provided on the first support stand 124a and come into contact with the lower surface of the second extension portion 302 when the second blank P2 is unloaded. Have. Thereby, while being able to simplify the 1st support part 118a, the 2nd extension part 302 of the 2nd blank P2 can be supported stably. The same applies to the second support part 118b and the third support part 118c.

  The plurality of first contact portions 126a are configured to be detachable from the first support base 124a. Thereby, replacement | exchange of the 1st contact part 126a can be performed easily. The same applies to the second contact portion 126b and the third contact portion 126c.

  Each of the plurality of first contact portions 126a includes a first pedestal 130a provided on the first support pedestal 124a, and a plurality of first support bodies 132a extending linearly upward from the first pedestal 130a. Have. The first support body 132a is configured to be elastically deformable in a direction intersecting with the extending direction.

  Therefore, the second extending portion 302 of the second blank P2 can be easily placed on the first contact portion 126a by elastically deforming the first support body 132a when the second blank P2 is carried out. The same applies to the second contact portion 126b and the third contact portion 126c.

  Each of the plurality of second support main bodies 132b is inclined in the carry-out direction of the second blank P2 upward from the second pedestal 130b. Thereby, the 2nd extension part 302 of the 2nd blank P2 can be put still more easily on a plurality of 2nd support main parts 132b. The same applies to the third support body 132c.

  The support device 40 includes a guide portion 122 for guiding the second extension portion 302 onto the first support portion 118a when the second blank P2 is carried out. Therefore, the extended end portion of the second extending portion 302 can be smoothly placed on the first support portion 118a by the guide portion 122 when the second blank P2 is carried out.

  The guide part 122 is located in a direction opposite to the carry-out direction of the second blank P2 with respect to the first support part 118a, and the guide part 122 is inclined upward toward the side where the first support part 118a is located. An inclined surface 134 is formed. Thereby, the extended end part of the 2nd extension part 302 can be reliably guided on the 1st support part 118a by the inclined surface 134 at the time of carrying out the 2nd blank P2.

  The upper end of the second support portion 118b is positioned downward as it approaches the first support portion 118a. Thereby, the site | part located between the 1st support part 118a and the 2nd support part 118b among the 2nd extension parts 302 can be easily curved in convex shape toward the downward direction.

  The support device 40 is positioned in a direction opposite to the carry-out direction of the second blank P2 relative to the first support part 118a, and supports the extended end of the second extended part 302 when the second blank P2 is carried out. It has the 3rd support part 118c. The upper end of the third support portion 118c is positioned above the upper surface of the workpiece end portion Wa when the second blank P2 is carried out. In this case, it is possible to further suppress the second extending portion 302 from coming into contact with the work end portion Wa when the second blank P2 is carried out.

  The third support portion 118c is separated from the second extension portion 302 with the first support portion 118a and the second support portion 118b supporting the second extension portion 302 when the second blank P2 is carried out. Thereby, when the 3rd support part 118c leaves | separates from the 2nd extension part 302, it can suppress that the 2nd extension part 302 contacts the workpiece | work edge part Wa.

  The upper end of the end portion in the direction opposite to the carry-out direction of the second blank P2 in the third support portion 118c is positioned below the upper end of the intermediate portion in the carry-out direction of the second blank P2 in the third support portion 118c. . Thereby, the 2nd extension part 302 can be easily mounted on the 3rd support part 118c at the time of carrying out the 2nd blank P2.

  The second blank P2 is made of a magnetic material, and the lower mold 26 has a transfer device 38 for carrying out the second blank P2. The transfer device 38 includes a magnet conveyor 94 that is attracted to the second blank P2, a raised position where the upper surface of the magnet conveyor 94 is located above the upper end of the lower blade 30, and an upper surface of the magnet conveyor 94 that is higher than the upper end of the lower blade 30. A conveyor elevating unit 98 that elevates and lowers the magnet conveyor 94 at a lower position located below.

  In this case, the magnet conveyor 94 can be reliably attracted to the second blank P2 by positioning the magnet conveyor 94 at the raised position. Thereby, the 2nd blank P2 can be carried out efficiently by the magnet conveyor 94. FIG. At this time, since the upper surface of the magnet conveyor 94 is located above the upper end of the lower blade 30, it is possible to suppress the second blank P2 adsorbed on the magnet conveyor 94 from interfering with the lower blade 30. it can. Furthermore, by positioning the magnet conveyor 94 at the lowered position, it is possible to prevent the workpiece W and the workpiece W from being attracted to the magnet conveyor 94 when the second blank P2 is not carried out.

  The processing apparatus according to the present invention is not limited to the above-described embodiment, and it is needless to say that various configurations can be adopted without departing from the gist of the present invention.
