Description

  The present invention relates to a work transfer device, and more particularly, to a device for transferring a work in a state in which a part other than a product is integrated with a part that finally becomes a product.

  For example, in the production process of a cast product, as described in Patent Document 1 below, a work (cast product) formed into a predetermined shape by a die casting machine is taken out by a take-out device equipped with a work take-out arm or the like. Are transferred to the trimming processing machine, and after removing the design parts such as biscuits and runners from the cast product with this processing machine, they are transported to the next process (finishing process etc.) by the conveyor. .

JP-A-6-155498

  By the way, recently, in this kind of field (casting process), there is an increasing need for a high cycle in the production process, and as described in Patent Document 1, the design part is removed by a trimming processor. Later, it has become necessary to review the process of transporting the cast product with the design part removed to the next step. That is, conventionally, the cast product has been removed from the die casting machine immediately after being taken out of the die casting machine, and then transported to the next process by a conveyor. However, the removal process of the design part hinders high cycle operation. Therefore, the removal process (trimming process) is omitted, in other words, the cast product is transported to the next process while leaving the plan part, and the plan part is removed together with finishing in the next process. Implementation is under consideration.

  However, when the cast product with the design part remaining is transported by a transport device such as a conveyor, the part protruding from the cast product such as the design part or burr interferes with the transport device and its surroundings, or the transport direction. There is a concern that castings adjacent to each other interfere with each other. For this reason, in order to avoid such a situation, it is necessary to increase the transport space per cast product, but in this case, the width and overall length of the conveyor must be increased more than necessary, so that the transport efficiency can be increased. Results in a contradiction to the lowering of the cycle and the higher cycle.

  Alternatively, even if there is no interference with the conveying device and its surroundings, the design part and the burr may fall off the product part of the cast product, and this may cause a situation where the conveying device stops. In addition, in order to increase the cycle, it is necessary to determine the workpiece transport posture (mounting posture on the conveyor) with an emphasis on workability in the transport destination process (ease of contact with the workpiece). However, depending on the type of workpiece, the balance may be greatly lost during conveyance, and there is a possibility that stable conveyance becomes difficult. As described above, in the conventional conveying device, it is difficult to stably convey the cast product, and this also causes a problem that it is difficult to achieve a high cycle of the production process.

  The above-mentioned problems are not limited to the production process of cast products. For example, in a state where parts other than the product (runners, gates, etc.) such as resin injection-molded products are integrated with the final product. In addition to the molded product to be molded, there is a concern about the same problem in the production process of workpieces that cannot be placed in contact with the entire conveyance surface of the conveyor, in other words, cannot be placed in a stable posture.

  In view of the above circumstances, high-cycle production processes can be achieved by efficiently and stably transporting workpieces in a state where parts other than products are integrated with parts that will eventually become products, regardless of the workpiece shape. Achieving this is a technical problem to be solved by the present invention.

  The solution to the above-described problem is achieved by the work transfer device according to the present invention. In other words, this transport device includes a plurality of rod-shaped members that can rotate around the longitudinal central axis, and a rotation control unit for controlling the rotation of the rod-shaped members, and the plurality of rod-shaped members are arranged at one end side in the longitudinal direction. Is disposed above the other end side so as to be inclined with respect to the horizontal direction and so that the workpiece can be placed across the plurality of rod-shaped members. It is characterized by the fact that the workpieces can be moved along the longitudinal direction of the rod-shaped member by controlling the rotation of the rod-shaped member with the rotation control unit in a state where the workpieces are placed in parallel with each other.

  Thus, according to this invention, the said workpiece | work is supported from the downward direction by each rod-shaped member by mounting a workpiece | work so that it may straddle a some rod-shaped member. Then, the rod-shaped member is rotated around the central axis in the longitudinal direction from this state, and the workpiece is moved along the longitudinal direction of the rod-shaped member by controlling the rotation at that time by the rotation control unit. Therefore, it can be stably conveyed without dropping the workpiece. In other words, by controlling the rotation of the bar-shaped member by the rotation control unit, the work can be transferred so that the balance during transfer is maintained according to the shape of the work and the mounting posture on the bar-shaped member. Therefore, for example, when a workpiece is a cast product, a workpiece in which a portion other than a product is integrated with a portion that will eventually become a product can be transported without causing interference with the surroundings, which is extra for avoiding interference. It is not necessary to provide a space around the work or around the transfer device. As a result, the workpieces can be transported at a reduced interval, which leads to an improvement in transport efficiency and a high cycle. In addition, since the work can be transported regardless of the mounting posture on the rod-shaped member, workability at the transport destination is increased, so that a high cycle can be expected. Further, since the workpiece is supported and transported by the plurality of rod-shaped members, even if a portion other than the product such as a burr drops off from the workpiece and falls, the rotation of the rod-shaped member does not stop. Therefore, it is possible to surely avoid the situation where the transfer line stops, and it is also possible to achieve a high cycle.

  Moreover, the workpiece conveyance apparatus which concerns on this invention WHEREIN: The rotation control part may be able to control individually the rotation direction and rotation speed of a some rod-shaped member.

  When a workpiece placed across a plurality of rod-like members is moved by rotation of the rod-like member as in the present invention, according to verification by the present inventor, depending on the workpiece, rotation of a plurality of rod-like members is performed. It was found that stable conveyance can be realized by changing the direction. It has also been found that the moving speed of the workpiece can be adjusted by varying the rotational speed between these rod-shaped members. Accordingly, by individually controlling the rotation direction and rotation speed of the plurality of rod-shaped members as described above, stable conveyance can be realized according to the shape of the workpiece and the mounting posture on the rod-shaped member. Further, since the workpiece conveyance speed can be adjusted according to the conveyance distance and cycle time, the versatility of the conveyance device can be further enhanced.

  Moreover, the workpiece conveyance apparatus which concerns on this invention may stop the workpiece | work currently moving along the longitudinal direction of a rod-shaped member by stopping rotation of all the rod-shaped members by a rotation control part. .

  In this way, the position of the workpiece on the rod-shaped member can be controlled by making it possible to stop the workpiece moving on the rod-shaped member by controlling the rotation of the rod-shaped member, so that a plurality of workpieces can be placed on the rod-shaped member. Can be aligned. Therefore, a plurality of workpieces can be efficiently conveyed toward the next process. Further, even if the conveyance work has to be temporarily stopped for some reason, the conveyance of the workpiece can be stopped quickly.

  Moreover, the workpiece conveyance apparatus according to the present invention further includes a rotation support portion that rotatably supports the rod-shaped member, and the rotation support portion is provided on the connection member, which is coupled to one end portion in the longitudinal direction of the rod-shaped member, You may be comprised by the small diameter part whose outer diameter is smaller than a rod-shaped member, and the receiving member which supports a small diameter part rotatably.

  By configuring the rotation support portion of the rod-shaped member in this way, for example, the outer diameter of the rotation support portion disposed on one end side in the longitudinal direction on the workpiece carry-out side is designed to be the same diameter or less than that of the rod-shaped member. be able to. Precisely, the shape and size of the upper part of the receiving member constituting the rotation support portion can be designed so as not to interfere with the work carried out from the conveying device (on the rod-shaped member). This is because the connecting member connected to one end in the longitudinal direction of the rod-shaped member is rotatably supported instead of the rod-shaped member itself. Therefore, according to this structure, it becomes possible to carry out smoothly, without lifting a workpiece | work.

  As described above, according to the present invention, regardless of the work shape, the production process can be performed by efficiently and stably transporting the work in a state in which the part other than the product is integrated with the part that finally becomes the product. It is possible to achieve a high cycle.

It is a principal part expanded sectional view of the workpiece conveyance apparatus shown in FIG. It is principal part sectional drawing of the workpiece conveyance apparatus shown in FIG. 1, Comprising: It is sectional drawing which shows an example of the mounting posture of a workpiece | work.

It is a top view for demonstrating an example of the usage condition of the workpiece conveyance apparatus shown in FIG. It is a principal part expanded sectional view which shows the other example of the mounting posture of a workpiece | work.

  Hereinafter, an embodiment of a work transfer device according to the present invention will be described with reference to the drawings. In this embodiment, a case where a cylinder block (cast product) of an engine molded by a die casting method is conveyed from a casting process to the next process will be described as an example. In the following description, the vertical direction is simply referred to as the vertical direction unless otherwise specified.

  FIG. 1 is a plan view showing an overall configuration of a workpiece transfer apparatus 10 according to an embodiment of the present invention. As shown in FIG. 1, the transport device 10 includes a plurality of rod-like members 11 that can rotate around a central axis X in the longitudinal direction, a rotation control unit 12 that controls the rotation of the rod-like member 11, and the rod-like member 11. And a rotation support portion 13 that rotatably supports the rotation. In this embodiment, as shown in FIG. 2, two rod-shaped members 11 are arranged in parallel with each other, and two workpieces W are placed so that the workpiece W can be placed across the two rod-shaped members 11. The interval between the rod-shaped members 11 is set to a predetermined size. In this embodiment, the rotation control unit 12 is dynamically connected to one end in the longitudinal direction of the rod-shaped member 11, and is connected to the rotation drive unit 14 that applies a driving force to the rod-shaped member 11, and the rotation drive unit 14. , And a control means 15 for controlling transmission of driving force by the rotation driving unit 14. Therefore, in this case, the rotation support portion 13 that rotates and supports one end side (work carry-in side) in the longitudinal direction of the rod-shaped member 11 is constituted by the rotation drive portion 14.

  The rod-shaped member 11 has a cylindrical outer peripheral surface, and is formed from, for example, a metal pipe such as SUS. Further, in this embodiment, the two rod-shaped members 11 have both a workpiece loading side end portion (left end portion in FIG. 2), which will be described later, and a workpiece unloading side end portion (right side in FIG. 2). It is arrange | positioned in the state inclined by the predetermined angle (for example, 5-10 degrees) with respect to the horizontal direction so that it may be located upwards compared with the edge part. As will be described later, this angular range allows the workpiece W being moved along the longitudinal direction of the rod-shaped member 11 to be stopped by stopping the rotation of all the rod-shaped members 11 and makes the rod-shaped member 11 stationary. In this state, the angular range is set so that the workpiece W placed on the rod-shaped member 11 does not move under its own weight.

  The rotation drive unit 14 constituting the rotation control unit 12 is configured by a motor, for example, and as shown in FIG. 1, the rotation axis of the rotation drive unit 14 and the central axis X in the longitudinal direction of each rod-shaped member 11 coincide with each other. Dynamically linked to Thereby, it is possible to rotate the rod-shaped member 11 around the central axis X in the longitudinal direction. Further, each rotation drive unit 14 is electrically connected to the control means 15, and the control means 15 can individually control the rotation direction, rotation speed, or rotation torque of each rod-like member 11. Therefore, by controlling the rotation of each rod-shaped member 11 by the rotation control unit 12 described above, the workpiece W placed across the two rod-shaped members 11 is moved along the longitudinal direction of the rod-shaped member 11 and the workpiece is carried out. It is possible to move (slide) toward the side (see FIGS. 5 and 6 to be described later). In addition, by stopping the rotation of all the bar-shaped members 11, it is possible to stop the workpiece W that is moving along the longitudinal direction of the bar-shaped members 11. In this way, the longitudinal position of the workpiece W on the rod-like member 11 can be adjusted.

  In this embodiment, the rotation support portion 13 that rotates and supports the other end in the longitudinal direction of the rod-shaped member 11, that is, the end on the workpiece carry-out side, is arranged at the end of the rod-like member 11 on the workpiece carry-out side as shown in FIG. The connecting member 16 is connected, the small-diameter portion 17 is provided on the connecting member 16 and has an outer diameter smaller than that of the rod-shaped member 11, and the receiving member 18 that rotatably supports the small-diameter portion 17. In this case, the connecting member 16 is fitted into the tubular member 20 integrally having the small-diameter portion 17 and the large-diameter portion 19 larger in diameter than the small-diameter portion 17, and the large-diameter portion 19 by fitting into the inner periphery of the tubular member 20. The connecting bolt 21 can be expanded in diameter, and the cap 22 is interposed between the tubular member 20 and the connecting bolt 21. The large diameter portion 19 is provided with slits (not shown) extending in the longitudinal direction at several locations in the circumferential direction. Accordingly, the large diameter portion 19 of the cylindrical member 20 is inserted into the inner periphery of the rod-shaped member 11 formed from a metal pipe material, and the small diameter portion 17 is disposed on the inner periphery of the slide bearing as the member 18. By fitting (tightening) the connecting bolt 21 to the inner periphery of the cylindrical member 20 from the small diameter portion 17 side, the large diameter portion 19 is expanded, and the cylindrical member 20 and the rod-shaped member 11 are connected. And the rod-shaped member 11 connected with the connection member 16 which has the cylindrical member 20 can be rotationally supported by rotating and supporting the small diameter part 17 of the cylindrical member 20 with the member 18. At this time, the outer diameter of the sliding bearing as the receiving member 18 is designed to be equal to or smaller than the outer diameter of the rod-shaped member 11.

  Hereinafter, an example of the conveyance mode of the workpiece | work W at the time of using the workpiece conveyance apparatus 10 of the said structure is demonstrated.

  First, as shown in FIG. 1, a cast product (work W) formed by a casting device (not shown) is taken out from the casting device by a robot arm or the like (not shown) and provided on the rod-like member 11 of the work transport device 10. Transfer to work receiving position 23. In this embodiment, since the workpiece W (cast product) immediately after being taken out from the casting apparatus is transferred onto the rod-shaped member 11, the cast product as the workpiece W is finally a product as shown in FIG. The portion Wa and the portion Wb other than the product such as the plan portion are integrated. Therefore, depending on the mounting posture, as shown in FIG. 4, the portion Wb other than the product refers to the rod-shaped member 11 and the width direction (horizontal direction and orthogonal to the longitudinal direction of the rod-shaped member 11). The workpiece W is placed across the two rod-shaped members 11 in the state of being in contact with each other.

  As described above, when the workpiece W is placed at a predetermined position (work receiving position 23) on the rod-shaped member 11 and supported from below by the two rod-shaped members 11, the next workpiece W is moved to the workpiece receiving position by the robot arm or the like. In the meantime, the two rotary members 14 (motors) are driven by commands from the control means 15 until the two rod-like members 11 dynamically connected to the rotary drive units 14 are transferred. Both are driven to rotate. At this time, the rotation direction, rotation speed, and the like of each rod-shaped member 11 are controlled according to the shape and placement posture of the workpiece W (see FIG. 4). In other words, the rotation direction of each rod-shaped member 11 is controlled by the control means 15 so that the balance is maintained without changing the posture of the workpiece W being conveyed. In the case of this illustrated example, as shown in FIG. 4, for example, by rotating the two rod-shaped members 11 in the same direction (in FIG. 4, the direction in which the design portion is pressed against the rod-shaped member 11), the workpiece receiving position 23. The workpiece W placed on the rod-shaped member 11 starts moving toward one side in the longitudinal direction of the rod-shaped member 11. Specifically, the workpiece W starts to slide from the position indicated by the two-dot chain line in FIG. 5 toward the position indicated by the solid line. And when it moves only the predetermined distance, the drive of the rotation drive part 14 is stopped and rotation of the rod-shaped member 11 is stopped. Along with this, the slide operation of the workpiece W is also ended and stopped at a position at the end (a position indicated by a solid line in FIG. 5).

  In this way, the workpiece W placed at the workpiece receiving position 23 is slid toward one side in the longitudinal direction of the rod-like member 11 and stopped after being moved by a predetermined distance. As shown in FIG. By repeating the operation of transferring the workpiece W ′ (cast product) formed by the apparatus to the empty workpiece receiving position 23 by the sliding operation, a plurality of workpieces W are aligned on the rod-shaped member 11 at predetermined intervals. It is conveyed sequentially in the state. Then, the workpiece W ″ that has reached the foremost side in the sliding direction is carried out of the workpiece transfer apparatus 10. At this time, as shown in FIG. 3, the receiving member 18 that constitutes the rotation support portion 13 on the workpiece carry-out side is designed to have an outer diameter that is the same as or smaller than that of the rod-shaped member 11. It does not protrude upward. Therefore, by continuing the slide operation of the workpiece W ″ as described above, the workpiece W ″ is transferred from the end of the rod-shaped member 11 on the workpiece carry-out side to the receiving member 18 and is directly outside the workpiece transfer device 10. Discharged. As a result, the workpiece W ″ is transferred to the next step (for example, although not shown, the plan portion removing step or the finishing processing step also serving as the plan portion removing step) disposed adjacent to the workpiece transfer apparatus 10. Is done.

  As described above, the rod-shaped member 11 is rotated around the central axis X in the longitudinal direction while the workpiece W is placed so as to straddle the plurality of rod-shaped members 11, and the rotation at that time is controlled by the rotation control unit 12. The workpiece W can be moved stably along the longitudinal direction of the rod-shaped member 11 by controlling in accordance with the above, so that the workpiece W can be stably conveyed without dropping. In other words, by controlling the rotation of the rod-shaped member 11 by the rotation control unit 12, the workpiece W is conveyed so that the balance during conveyance is maintained according to the shape of the workpiece W and the mounting posture on the rod-shaped member 11. Can do. In particular, in this embodiment, as shown in FIG. 4, the rod-shaped member 11 is rotated in a direction in which the design portion (part Wb other than the product) is pressed against the one rod-shaped member 11. Functions as a guide and can be transported more reliably. Therefore, the work part (the part Wb other than the product) can be transported without interfering with the surroundings in a state where the plan part (part Wb other than the product) is finally integrated with the part Wa to be the product, and extra space for avoiding interference can be obtained. It is not necessary to provide around. As a result, the work W can be transported with a small interval, which leads to an improvement in transport efficiency and a high cycle. In addition, since the workpiece W can be transported regardless of the mounting posture on the rod-shaped member 11, the mounting posture can be determined with priority given to workability in the next process as a transport destination, and this is also a high cycle. Can be expected. In addition, since the workpiece W is supported and transported by the plurality of rod-shaped members 11, even if a portion Wb other than the product such as a burr drops off from the workpiece W and falls, the rotation of the rod-shaped member 11 does not stop. Absent. Therefore, it is possible to surely avoid the situation where the transfer line stops, and it is also possible to achieve a high cycle.

  In this embodiment, since the rotation control unit 12 can individually control the rotation direction and rotation speed of the plurality of rod-like members 11, the workpiece can be stabilized regardless of the shape and placement posture of the workpiece. Can be conveyed. For example, when a workpiece W having a shape as shown in FIG. 7 is conveyed, the balance is maintained without changing the posture of the workpiece W by rotating the two rod-shaped members 11 in different directions (inward in the width direction, respectively). It becomes possible to carry in the state. Moreover, since the moving speed of the workpiece | work W can also be raised by raising the rotational speed of these rod-shaped members 11, the conveyance speed of the workpiece | work W can also be adjusted according to a conveyance distance and cycle time. In addition, the workpiece | work W and the rod-shaped member 11 convey as a reason which can control the movement (slide) operation | movement of the workpiece | work W in a mounting state by controlling the rotation direction, rotational speed, etc. of the rod-shaped member 11 as mentioned above. It is considered that the contact is made along the direction and the contact area is small, the work W is a cast product, and the surface thereof is a molding surface, so that the surface is relatively rough. In other words, if the workpiece W to be conveyed is a cast product, it is preferable because the conveyance of the workpiece W can be more easily controlled in a desired manner.

  Moreover, since the workpiece | work W was supported and conveyed by the two rod-shaped members 11 like this embodiment, the exposed area of the workpiece | work W in conveyance is large. Therefore, when the workpiece W is cooled while the workpiece W (cast product) immediately after casting is conveyed by the workpiece conveyance device 10, the area where the cooling water or the like can be sprayed is increased, and the cooling efficiency is increased. Moreover, since the lower part of the workpiece | work W is vacant at the time of conveyance, since cooling water can be discharged | emitted below, this point is also suitable for cooling. Further, as described above, when the workpiece W is a cast product, the rod-like member 11 that supports the workpiece W can be formed of a metal such as SUS, so that it does not rust even if the cooling water adheres. Further, even if the workpiece W immediately after placement is at a high temperature, it is not necessary to receive thermal damage. Furthermore, since it has been proved by the inventor that the workpiece W can be conveyed in a desired manner by controlling the rotation of the rod-shaped member 11 even under the presence of water, there is no problem in this respect as well.

  In addition, as described above, according to the workpiece transfer device 10 according to the present invention, stable transfer can be realized regardless of the shape of the workpiece W, so that a plurality of types of workpieces W can be transferred in a single line. . As a result, it is possible to reduce the number of transport lines and thus reduce the equipment cost. In addition, since the workpiece transfer device 10 described above can have a very simple structure, the manufacturing cost can be reduced.

  As mentioned above, although one Embodiment of the workpiece conveyance apparatus which concerns on this invention was described, this conveyance apparatus and the conveyance method using this conveyance apparatus are not limited to the said illustration form, Arbitrary within the scope of the present invention. It is possible to take the form.

  For example, in the above-described embodiment, the case where the rod-shaped member 11 is formed of a metal pipe has been described. Of course, the solid rod-shaped member 11 may be formed by cutting out a columnar metal rod. Depending on the weight of the workpiece W, when it is difficult to stably support the workpiece W with only the two rod-shaped members 11, three or more rod-shaped members 11 are arranged in parallel. You may make it install.

  Further, regarding the rotation control of the rod-shaped member 11 by the rotation control unit 12, for example, if the rotation directions of the plurality of rod-shaped members 11 are the same, the rotation drive unit 14 is connected to only one of the rod-shaped members 11, and this rotation drive unit The rotational driving force from 14 may be transmitted to the other rod-shaped member 11 side via a chain or the like. Further, depending on the type and placement state of the workpiece W, only some of the rod-shaped members 11 are rotationally driven, and the remaining rod-shaped members 11 are stopped so that the workpiece W is conveyed. It may be. Or in the said embodiment, although the space | interval of the several (2) rod-shaped member 11 is maintained at the fixed magnitude | size, it can respond to the workpiece | work W from which the width direction dimension differs greatly by making the said space | interval variable. It may be.

  In the above embodiment, the operation of stopping the slide of the workpiece W is performed by stopping the rotation of the rod-shaped member 11 after the workpiece W loaded (transferred) to the workpiece receiving position 23 is slid by a predetermined distance. As described above, the case of carrying out of the workpiece transfer apparatus 10 has been described. However, the workpiece W can be carried in and out without stopping the rotation of the rod-shaped member 11. For example, although not shown, it is possible to slide the rod-shaped member 11 to the unloading position without stopping the workpiece W and stopping the workpiece W. At this time, a stopper (not shown) may be provided near the carry-out position by utilizing the fact that the workpiece W slides on the outer peripheral surface of the rod-shaped member 11. Thereby, the pitch between the plurality of workpieces W located in the vicinity of the carry-out position can be narrowed compared to the carry-in side, or the carry-out standby can be performed in a state where the adjacent works W are in contact with each other. Thereby, it is possible to appropriately carry the accumulator while shortening the overall length of the transport device 10.

  In the above embodiment, the case where the cylinder block of the engine is cast and transferred from the casting apparatus to the next process has been described as an example. However, the present invention is also applied to transfer between processes other than the above. Is possible. Further, the workpiece W to be transported is not limited to the above-described components. For example, in addition to molded products that are molded in a state where parts other than the product (runners, gates, etc.) are integrated with the final product, such as resin injection molded products, The present invention can also be applied to conveyance of a workpiece (for example, a forged product such as a crankshaft) that cannot be placed in contact, in other words, cannot be placed in a stable posture.

  Of course, other specific forms can be adopted for matters other than the above as long as the technical significance of the present invention is not lost.
