Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the press working area of a press machine, a rear end material of a coil is generated by processing the coil material. This rear end material of the coil includes a product material of a predetermined fixed length and a short-sized defective material. The product material is used for products, and the defective material is discarded. It is necessary to remove the rear end material of the coil from the press working area after processing the coil material. The removal operation of the rear end material of the coil is preferably automatically performed using removal equipment installed on the downstream side of the press machine, rather than manually by an operator directly accessing the press working area. In this case, even if the space required for installing the removal equipment is limited, a technology that enables the reliable removal of the long rear end material of the coil from the press working area of the press machine is required.

[0005] The present invention has been made in view of such problems, and an object thereof is to provide an apparatus for removing a rear end material of a coil that can remove the rear end material of the coil generated by a press machine without manual labor even in the case of a long coil. [Means for solving the problem]

[0006] One aspect of the present invention is, A coil end material removal device for removing coil end material generated by a press machine from the press working area, The main body is placed alongside the above-mentioned press machine, A transport conveyor is provided below the main body outside the area of ​​the press working region, for transporting the coil end material removed from the press working region downstream. A holding unit for holding the rear end material of the above coil, A plurality of movable bodies are interposed between the main body and the holding unit, and are slidably connected to each other in the front-to-back direction so that the relative position of the holding unit with respect to the main body in the front-to-back direction is variable. Multiple drive units that each slide-drive one of the above multiple movable bodies, The holding unit is relative to the main body The position located between the above-mentioned discharge conveyor and From the above press working area of ​​the above press machine Position to be placed A control unit controls the multiple drive units so that they move in multiple stages in the forward and backward direction via the multiple movable bodies up to that point, A coil rear end material removal device equipped with, It is located there. [Effects of the Invention]

[0007] In the coil end material removal device described above, a plurality of movable bodies interposed between the main body and the holding unit for holding the coil end material are connected to each other so as to be slidable in the front-rear direction, such that the front-rear relative position of the holding unit with respect to the main body is variable. By controlling the drive unit of each of the plurality of movable bodies with the control unit, the holding unit moves in multiple stages in the front-rear direction from the main body side to the press working area of ​​the press machine via the plurality of movable bodies. In other words, the holding unit is extended to the press working area of ​​the press machine or shortened toward the main body side, using a principle similar to that of a so-called "telescopic hanging rod structure".

[0008] This structure allows for a relatively short front-to-back dimension of the part supporting the holding unit, while still providing sufficient front-to-back stroke for removing the coil end material from the press working area of ​​the press machine. This makes it possible to remove long coil end materials from the press working area of ​​the press machine, not only when there are no restrictions on the front-to-back space required for installing the removal equipment, but also when this space is limited. In short, it reduces the constraints on the front-to-back length of the coil end material. Furthermore, since the holding unit moves automatically under control by the control unit, it eliminates the need for manual work that would otherwise require the operator to directly access the press working area.

[0009] As described above, according to the above embodiment, it is possible to provide a coil end material removal device that can remove coil end material generated by a press machine without manual labor, even if the coil end material is long. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0011] Preferred embodiments of the above aspects will be described below.

[0012] In the coil rear end material extraction device of the above aspect, the plurality of movable bodies are composed of a mounting member integrated with the holding unit and a support mechanism unit that supports the mounting member slidably in the front-rear direction, and it is preferable that the support mechanism unit is supported slidably in the front-rear direction by the main body unit.

[0013] According to this extraction device, by using a mounting member integrated with the holding unit and a support mechanism unit that supports the mounting member slidably in the front-rear direction and is also supported slidably in the front-rear direction by the main body unit as movable bodies, the structure for extending the holding unit to the press working area of the press machine or shortening it toward the main body unit side can be simplified.

[0014] In the coil rear end material extraction device of the above aspect, the support mechanism unit has a slide cylinder extending in the front-rear direction for supporting the mounting member slidably in the front-rear direction. The slide cylinder has a cylinder part containing a piston and a slider connected to the piston, and it is preferable that the slider is fixed to the mounting member.

[0015] According to this extraction device, a structure for sliding the mounting member integrated with the holding unit in the front-rear direction by using the slide cylinder can be constructed.

[0016] In the above-described embodiment, the coil rear end material removal device preferably includes a lifting drive unit that moves the slide cylinder up and down in the vertical direction.

[0017] This retrieval device allows for the construction of a structure in which a slide cylinder supporting a mounting member integrated with a holding unit is raised and lowered vertically using a lifting drive unit.

[0018] In the coil rear end material removal device according to the above-described embodiment, it is preferable that the holding unit, the mounting member, and the slide cylinder are arranged so that they are side by side when viewed from the front-to-back direction.

[0019] This extraction device allows for the removal of coil end material by arranging the holding unit, mounting member, and slide cylinder, all of which enter the press working area for extraction, side by side. This reduces the vertical height dimension. Therefore, even if the press working area of ​​the press machine is a narrow space with limited height, it becomes possible to extract the coil end material from the press working area.

[0020] (Embodiment) The following describes a specific embodiment of the coil material processing equipment with reference to Figures 1 to 12.

[0021] In the diagrams used for this explanation, unless otherwise specified, the front-to-back direction along the coil material's feed direction X1 is indicated by arrow X, the left-to-right direction perpendicular to the front-to-back direction is indicated by arrow Y, and the up-to-down direction perpendicular to the front-to-back direction is indicated by arrow Z.

[0022] 1. Overall configuration of coil material processing equipment 1 As shown in Figure 1, the coil material processing equipment 1 is equipment for processing coil material C. The main components of this processing equipment 1 are an uncoiler 2, a leveler 3, a downlooper 4, a feeder 5, a press 6, and a coil end material removal device 10 (hereinafter simply referred to as "removal device 10").

[0023] The uncoiler 2 is equipped with a coil inner diameter holder and a coil outer diameter holder so that the coil material C can be unwound freely. The leveler 3 has the function of flattening the strip-shaped coil material C that has been unwound from the coil material C. The coil material C that has been flattened by the leveler 3 is introduced to the press machine 6 via the downlooper 4 and feeder 5. In the press machine 6, in the press working area 7 which is divided into upper and lower sections by the lower die D1 and the upper die D2, processing is performed such as cutting the coil material C to the desired length or punching holes in the coil material C. When the rear end of the coil material C is cut in the press working area 7 of the press machine 6, coil rear end material W is generated. Coil rear end material W includes product material of a predetermined length and short pieces of missing material. The product material is used for the product, and the missing material is discarded. The removal device 10 is for removing the coil rear end material W generated in the press machine 6 from the press working area 7. The following describes, as an example, the case of extracting the coil end material W, which will be used as the product material.

[0024] 2. Structure of the extraction device 10 As shown in Figure 2, the extraction device 10 comprises a main body 20, a holding unit 30, a mounting member 41, and a support mechanism 42. The main body 20 is positioned alongside the press machine 6. That is, the main body 20 is located adjacent to the upright 6a of the press machine 6 on the downstream side in the feed direction X1. Below the main body 20, an extraction conveyor 24 is provided for transporting the coil end material W extracted from the press working area 7 of the press machine 6 downstream.

[0025] The holding unit 30 is for holding the coil end material W in the press working area 7 of the press machine 6. This holding unit 30 is composed of suction pads 31. The suction pads 31 are connected to a suction machine 54 (see Figure 5) through a connecting hose. Therefore, when the suction machine 54 is operating, the space around the suction pads 31 is depressurized, and an adhesive effect occurs on the opening surface of the suction pads 31. The suction pads 31 can hold the coil end material W by adsorption along their opening surface. In contrast, when the suction machine 54 is stopped, the depressurization of the space around the suction pads 31 is released, and the adhesive effect of the suction pads 31 disappears. To stably hold the coil end material W by adsorption, it is preferable to increase the number of suction pads 31.

[0026] The mounting member 41 is integrated with the holding unit 30. The support mechanism 42 has the function of supporting the mounting member 41 so that it can slide in the front-rear direction X. Therefore, the mounting member 41 is a movable part with respect to the support mechanism 42. The mounting member 41 is driven to slide in the front-rear direction X, with the air supply unit 51 (see Figure 5) as the drive unit. The air supply unit 51 is controlled by the control unit 60. The holding unit 30 is designed to slide in the front-rear direction X from the initial position P1 to the holding position P2 relative to the slide cylinder 43 in accordance with the movement of the mounting member 41. The holding position P2 is a position moved closer to the press machine 6 than the initial position P1.

[0027] The support mechanism 42 is supported by the main body 20 so as to be slidable in the front-rear direction X. Therefore, the support mechanism 42 is a movable part relative to the main body 20. The support mechanism 42 is slidable in the front-rear direction X relative to the main body 20 between a first position Q1 and a second position Q2. The sliding motion of the support mechanism 42 is guided by a guide roller 42a (see Figures 3 and 4) interposed between it and the main body 20. The second position Q2 is a position moved closer to the press machine 6 than the first position Q1.

[0028] The support mechanism 42 can be fixed in place by stoppers provided at the front and rear ends of the lower surface of the main body 20. When the support mechanism 42 is fixed in place at one end of the main body 20, the position of the support mechanism 42 in the front-rear direction X is set to the first position Q1. When the support mechanism 42 is fixed in place at the other end of the main body 20, the position of the support mechanism 42 in the front-rear direction X is set to the second position Q2.

[0029] The support mechanism 42 is belt-driven and is driven by a motor 52 (see Figures 2 and 5) that rotates the belts 21 and 22, sliding in the forward / backward direction X. The motor 52 is controlled by the control unit 60.

[0030] As shown in Figures 2 to 4, the support mechanism 42 includes a slide cylinder 43 extending in the front-rear direction X to support the mounting member 41 so that it can slide in the front-rear direction X, and a lifting drive unit 53 that moves the slide cylinder 43 up and down in the vertical direction Z from an up position R1 (see Figures 2 and 3) to a down position R2 (see Figure 4). The slide cylinder 43 has a cylindrical cylinder part 43a containing an air-driven piston 43b, and a slider 43c connected to the piston 43b. The slide cylinder 43 is called a "rodless cylinder". The lifting drive unit 53 is composed of an air cylinder or an electric cylinder, etc.

[0031] In the slide cylinder 43, the slider 43c slides in the forward / backward direction X relative to the cylinder portion 43a in conjunction with the forward / backward movement X of the piston 43b. This sliding motion of the slider 43c is guided by a guide member 43d (see Figures 3 and 4) interposed between the slider 43c and the cylinder portion 43a. The slider 43c, which slides relative to the cylinder portion 43a, is integrally fixed to the mounting member 41. Therefore, the mounting member 41 becomes a movable part of the slide cylinder 43 relative to the cylinder portion 43a.

[0032] The mounting member 41 can be secured by stoppers provided at the front and rear ends of the cylinder portion 43a. When the mounting member 41 is secured at one end of the cylinder portion 43a, the position of the holding unit 30 in the front-rear direction X relative to the slide cylinder 43 is set to the initial position P1. Conversely, when the mounting member 41 is secured at the other end of the cylinder portion 43a, the position of the holding unit 30 in the front-rear direction X relative to the slide cylinder 43 is set to the holding position P2.

[0033] As shown in Figures 3 and 4, the holding unit 30, the mounting member 41, and the slide cylinder 43 are arranged so that they are aligned side by side in the left-right direction Y when viewed from the front-rear direction X.

[0034] As shown in Figure 5, the control unit 60 outputs control signals to the air supply unit 51, the motor 52, the lifting drive unit 53, and the suction unit 54 at preset timings.

[0035] As described above, the mounting member 41 and the support mechanism 42 are interposed between the main body 20 and the holding unit 30, and are movable bodies that are slidably connected to each other in the front-rear direction X so that the relative position of the holding unit 30 in the front-rear direction X with respect to the main body 20 is variable. The control unit 60 is configured to control the drive unit of the mounting member 41 (air supply machine 51) and the drive unit of the support mechanism 42 (motor 52), respectively, so that the holding unit 30 moves in multiple stages in the front-rear direction X via the mounting member 41 and the support mechanism 42 from the initial position P1 on the main body 20 side to the holding position P2 on the press machine 6 side.

[0036] 3. Operation of the extraction device 10 Next, the operation of the extraction device 10 with the above configuration will be explained with reference to Figures 6 to 12. When extracting the coil end material W generated by the press machine 6 from the press working area 7, the extraction device 10 performs the following steps in stages. This operation is performed entirely automatically by the control unit 60 from the initial state shown in Figure 2.

[0037] 3-1. First Operational Stage As shown in Figure 6, in the first operating stage of the extraction device 10, the lifting drive unit 53 lowers the slide cylinder 43 from the raised position R1 (see Figure 2) to an arbitrary intermediate position R3 relative to the support mechanism 42. This causes the slide cylinder 43 to descend relative to the support mechanism 42. At this time, the front-rear position of the holding unit 30 relative to the slide cylinder 43 is maintained at the initial position P1, and the front-rear position of the support mechanism 42 relative to the main body 20 is maintained at the first position Q1.

[0038] 3-2. Second Operational Stage As shown in Figure 7, in the second operating stage of the extraction device 10, the air supply unit 51 (see Figure 5) slides the holding unit 30 from the initial position P1 to the holding position P2 relative to the slide cylinder 43. At this time, the front-to-back position of the support mechanism 42 relative to the main body 20 is maintained at the first position Q1, and the vertical position of the slide cylinder 43 relative to the support mechanism 42 is maintained at the intermediate position R3.

[0039] 3-3. Third Operational Stage As shown in Figure 8, in the third operating stage of the extraction device 10, the motor 52 slides the support mechanism 42 relative to the main body 20 from the first position Q1 to the second position Q2. Alternatively, the support mechanism 42 may be stopped at any position before the second position Q2. This causes the holding unit 30 to enter the press working area 7 of the press machine 6 and be positioned directly above the coil end material W. At this time, the front-rear position of the holding unit 30 relative to the slide cylinder 43 is maintained at the holding position P2, and the vertical position of the slide cylinder 43 relative to the support mechanism 42 is maintained at the intermediate position R3. According to the first operating stage in Figure 6 and the third operating stage in Figure 8, the holding unit 30 extends in a two-stage stroke.

[0040] 3-4. Fourth Operational Stage As shown in Figure 9, in the fourth operating stage of the extraction device 10, the lifting drive unit 53 (see Figure 5) lowers the slide cylinder 43 from the intermediate position R3 (see Figure 8) to the lowered position R2 relative to the support mechanism 42. As a result, the suction pad 31 of the holding unit 30 comes into contact with the upper surface of the coil rear end material W. In this state, the holding unit 30 can hold the coil rear end material W by operating the suction device 54 (see Figure 5). At this time, the front-rear position of the holding unit 30 relative to the slide cylinder 43 is maintained at the holding position P2, and the front-rear position of the support mechanism 42 relative to the main body 20 is maintained at the second position Q2.

[0041] 3-5. Fifth Action Stage As shown in Figure 10, in the fifth operating stage of the extraction device 10, the motor 52 slides the support mechanism 42 from the second position Q2 to the first position Q1 relative to the main body 20. As a result, the coil rear end material W is held by the holding unit 30, and a portion of it is pulled out towards the extraction device 10. At this time, the front-to-back position of the holding unit 30 relative to the slide cylinder 43 is maintained at the holding position P2, and the vertical position of the slide cylinder 43 relative to the support mechanism 42 is maintained at the second position R2. Alternatively, during this fifth operating stage, the lifting drive unit 53 may be used to raise the slide cylinder 43 from the lowered position R2 to any position relative to the support mechanism 42.

[0042] 3-6. Sixth Action Stage As shown in Figure 11, in the sixth operating stage of the extraction device 10, the air supply unit 51 (see Figure 5) slides the holding unit 30 from the holding position P2 to the initial position P1 relative to the slide cylinder 43. As a result, the coil rear end material W is pulled out towards the extraction device 10 while being held by the holding unit 30. At this time, the front-to-back position of the support mechanism 42 relative to the main body 20 is maintained at the first position Q1, and the vertical position of the slide cylinder 43 relative to the support mechanism 42 is maintained at the lowered position R2. According to the fourth operating stage in Figure 9 and the sixth operating stage in Figure 11, the holding unit 30 is shortened in a two-stage stroke.

[0043] 3-7. Seventh Operational Stage As shown in Figure 12, in the seventh operating stage of the extraction device 10, the operation of the suction device 54 (see Figure 5) is stopped, and the holding unit 30 releases the holding of the coil rear end material W. Then, the lifting drive unit 53 raises the slide cylinder 43 from the lowered position R2 (see Figure 11) to the raised position R1 relative to the support mechanism 42. At this time, the front-rear position of the holding unit 30 relative to the slide cylinder 43 is maintained at the initial position P1, and the front-rear position of the support mechanism 42 relative to the main body 20 is maintained at the first position Q1.

[0044] Furthermore, while the above-described operation of the removal device 10 is for removing the coil end material W when it is the product material, it goes without saying that this operation can also be applied to removing the coil end material W when it is a shorter piece of material than the product material.

[0045] According to the above-described embodiment, the following effects and advantages can be obtained.

[0046] In the extraction device 10, the mounting member 41 and the support mechanism 42, which are movable bodies interposed between the main body 20 and the holding unit 30 for holding the coil rear end material W, are slidably connected to each other in the front-rear direction X so that the relative position of the holding unit 30 with respect to the main body 20 in the front-rear direction X is variable. By controlling the respective drive units (air supply machine 51 and motor 52) of the mounting member 41 and the support mechanism 42 with the control unit 60, the holding unit 30 moves in multiple stages in the front-rear direction X from the main body 20 side to the press working area 7 of the press machine 6 via the mounting member 41 and the support mechanism 42. This structure utilizes a principle similar to that of a telescopic hanging rod structure, and the holding unit 30 can be extended to the press working area 7 of the press machine 6 or shortened toward the main body 20 side. In this embodiment, generally, the holding unit 30 extends and retracts in the front-rear direction X by a two-stage stroke resulting from the sliding motion of the mounting member 41 and the sliding motion of the support mechanism 42.

[0047] According to this structure, even if the dimension in the front-to-back direction X of the part supporting the holding unit 30 is kept relatively short, it is possible to gain sufficient stroke in the front-to-back direction X of the holding unit 30 for removing the coil end material W from the press working area 7 of the press machine 6. As a result, it becomes possible to remove long coil end material W from the press working area 7 of the press machine 6, not only when there is no restriction on the space in the front-to-back direction X required for the installation of the removal equipment 20, but also when this space is limited. In short, it becomes less constrained by the length dimension in the front-to-back direction X of the coil end material W. Furthermore, since the holding unit 30 moves automatically under the control of the control unit 60, it does not require manual work that would otherwise require an operator to directly access the press working area 7.

[0048] As described above, according to the above embodiment, it is possible to provide a coil end material removal device 10 that can remove coil end material W generated by the press machine 6 without manual labor, even if the coil end material is long.

[0049] With the above configuration of the removal device 10, by making the mounting member 41, which is integrated with the holding unit 30, and the support mechanism 42, which supports the mounting member 41 so as to be slidable in the front-rear direction X and is also supported by the main body 20 so as to be slidable in the front-rear direction X, movable parts, the structure for extending the holding unit 30 to the press working area 7 of the press machine 6 or shortening it toward the main body 20 can be simplified.

[0050] According to the above configuration of the removal device 10, a structure can be constructed in which the mounting member 41, which is integrated with the holding unit 30, is slid in the front-rear direction X using the slide cylinder 43.

[0051] According to the above configuration of the extraction device 10, a structure can be constructed in which the slide cylinder 43, which supports the mounting member 41 integrated with the holding unit 30, is raised and lowered in the vertical direction Z using the lifting drive unit 53.

[0052] With the above configuration of the extraction device 10, the holding unit 30, mounting member 41, and slide cylinder 43, all of which enter the press working area 7 for the extraction of the coil rear end material W, are arranged side by side, thereby reducing the height dimension in the vertical direction Z. Therefore, even if the press working area 7 of the press machine 6 is a narrow space with a limited height dimension, it becomes possible to extract the coil rear end material W from the press working area 7.

[0053] The present invention is not limited to the typical embodiments described above, and various applications and modifications are conceivable as long as they do not depart from the purpose of the invention. For example, the following embodiments can be implemented by applying the embodiments described above.

[0054] In the above-described embodiment, a structure in which the holding unit 30 extends and retracts in the front-rear direction X with a two-stage stroke was illustrated, but if necessary, a structure in which the holding unit 30 extends and retracts in the front-rear direction X with three or more stages of stroke may be adopted.

[0055] The specific structure of the drive unit controlled by the control unit 60 is not limited to that described in the above-described embodiment, and various actuator structures can be used.

[0056] In the above-described embodiment, the holding unit 30 is illustrated by a suction pad 31, but instead, the holding unit 30 may be made up of suction members such as permanent magnets or electromagnets.

[0057] In the above-described configuration, a case is described in which a lifting drive unit 53 is provided to raise and lower the slide cylinder 43 in the vertical direction Z. However, if the lifting and lowering operation of the slide cylinder 43 in the vertical direction Z is not required to remove the coil rear end material W, the lifting drive unit 53 may be omitted as needed.
