  Hereinafter, a long work processing apparatus according to an embodiment of the present invention will be described with reference to the drawings. A work processing machine 1 for processing a long work is a horizontal type for cutting a long work W. A case of a band saw will be described. In addition, as a long workpiece | work, there exist various long materials, such as a bar material, a pipe material, a shape steel, for example. And as an example of processing of long work W, not only cutting processing but various processings, such as laser processing and drilling with a drill, are performed. Accordingly, although the workpiece processing machine 1 will be described using a horizontal band saw, the workpiece processing machine 1 is not limited to the horizontal band saw.

  Referring to FIG. 1 which is a plan view, a workpiece processing machine (horizontal band saw) 1 for cutting a long workpiece W sandwiches a workpiece W long in the front-rear direction (Y-axis direction) and moves forward. A feeding vise 3 that intermittently feeds material is provided so as to be movable back and forth. The structure and operation of the feeding vise 3 are already well known. However, in order to facilitate understanding, the configuration and operation of the material feeding vice 3 will be briefly described.

  A horizontal band saw as an example of the workpiece processing machine 1 includes a vise device (not shown) for holding and fixing the workpiece W, and feeds the long workpiece W to the workpiece cutting position by the band saw blade. The feeding vise 3 is provided as a vice apparatus for performing the above. The material feeding vise 3 includes a vise bed 9 that is movable back and forth along a front and rear guide member 7 provided in the base frame 5 of the workpiece processing machine 1. A fixed vise jaw 9 </ b> A that presses one side of the workpiece W in the left-right direction is provided on one end side in the X-axis direction (left-right direction) of the vise bed 9. A movable vise jaw 9B that presses the other side of the workpiece W is provided so as to be able to reciprocate in a direction (left-right direction) that approaches and separates from the fixed vise jaw 9A.

  Therefore, when the workpiece W is loaded onto the roller frame in the front-rear direction provided in the base frame 5, the workpiece W is sandwiched from the left and right by the fixed vise jaw 9A and the movable vise jaw 9B, and the front direction (FIG. 1). In the left direction). The configurations of the roller frame and the feeding vise 3 are already well known. Therefore, a more detailed description of the feeding material vice 3 and the like is omitted.

  As understood from the above description, in order to process a long workpiece W by the workpiece processing machine 1, the front end portion of the workpiece W is carried into the feeding operation area by the feeding vise 3, It is necessary to carry in the workpiece W to the machining position in the workpiece machining machine 1 by the material feeding vise 3. Note that the work is carried in by the material feeding vise 3 by appropriately repeating the operations of clamping the workpiece W by the vice jaws 9A and 9B → advance → clamp release → retraction → work clamp → advance.

  In view of this, on the rear side of the roller frame that supports the workpiece W fed by the feeding vise 3, a workpiece conveyance path 11 for conveying the workpiece W long in the front-rear direction to the front is provided long in the front-rear direction. It has been. More specifically, the work conveyance path 11 is composed of a roller frame 15 provided with a plurality of support rollers 13 that support the work W at appropriate intervals in the front-rear direction.

  On one side of the roller frame 15 in the left-right direction (X-axis direction), a plurality of scissors rollers 17 are rotatably provided at appropriate intervals in the front-rear direction. The saddle roller 17 serves as a reference surface in the fixed vise jaw 9A of the feeding vise 3 in the workpiece processing machine 1 (the reference in the X-axis direction when the workpiece W is clamped by the fixed vise jaw 9A and the movable vise jaw 9B). Surface). Accordingly, when the workpiece W is brought into the material feeding vise 3 while maintaining the state where the workpiece W is in contact with the saddle roller 17, one side of the workpiece W in the X-axis direction is carried in a state in which the workpiece W coincides with the reference plane. Will be. Therefore, when the workpiece W is carried into the workpiece processing machine 1, it is not necessary to position the workpiece W again at the reference position in the X-axis direction.

  In the roller frame 15, a plate-like safety guard 19 is erected on the other side in the left-right direction. Therefore, the work W on the work transport path 11 is not inadvertently brought into contact with the work from the other direction, and the safety can be improved.

  On one side of the workpiece conveyance path 11, a material supply table 21 is provided. The material supply table 21 supports a plurality of long workpieces W transported (carried in) to the workpiece transport path 11. More specifically, the length of the feed table 21 in the front-rear direction is substantially equal to the length of the work transfer path 11 as shown in FIG. As shown in FIG. 4, the supply base 21 includes a frame body frame 23 in which steel materials are appropriately combined. A support frame 25 that supports the workpiece W is provided on the upper portion of the frame 23 so as to be inclined.

  More specifically, an appropriate position of the support frame 25 on the work transport path 11 side is supported by the frame body frame 23 via the pivot 27 so as to be vertically rotatable. A vertical movement actuator 29 such as a fluid pressure cylinder for rotating the support frame 25 up and down is provided at a position away from the work transfer path 11. Therefore, the support frame 25 can be tilted from the horizontal state by operating the vertical movement actuator 29.

  In the support frame 25, a stopper 31 for positioning the long workpiece W on the support frame 25 is provided on the upper surface of the end portion on the workpiece conveyance path 11 side. A positioning stopper 33 (see FIG. 1) for positioning the front end (tip) of the long workpiece W is provided at a front position (position on the workpiece processing machine 1 side) on the support frame 25.

  Therefore, for example, when the workpiece W is transported onto the supply table 11 by a crane or the like and placed on the support frame 25, the tip (front end) of the workpiece W is brought into contact with the positioning stopper 33, thereby supporting the support frame 25. The tip positions of the upper workpieces W are aligned with the reference position (position of the positioning stopper 33). That is, the plurality of long workpieces W on the support frame 25 are held in parallel with the workpiece conveyance path 11 and in a state where the tip ends are aligned with the reference position.

  With the above-described configuration, when the support frame 25 is tilted by the vertical movement actuator 29, the longest workpiece W on the support frame 25, that is, the longest workpiece W closest to the workpiece conveyance path 11 contacts the stopper 31 and is in a predetermined position. Positioned. The long workpieces W on the support frame 25 are aligned in contact with each other. By returning the support frame 25 to the original horizontal state, the restraining force due to mutual contact of the long workpieces W is alleviated, and the desired long workpiece W, for example, the workpiece W that is closest to the workpiece conveyance path 11. Can be lifted.

  On the support frame 25, there is provided a work transfer device 35 for lifting the long work W closest to the stopper 31 and transferring (loading) the long work W onto the work transfer path 11. That is, the feed stand 21 is provided with a traverser 37 (see FIG. 6) that can reciprocate between the workpiece transfer path 11 and the feed stand 21 so as to be movable up and down.

  More specifically, a plurality of guide frames 39 are provided in the frame body frame 23 of the material supply base 21. As shown in FIG. 4, each guide frame 39 is provided so as to be lower than the upper surface position where the support frame 25 is horizontally lowered and inclined in the longitudinal direction of the work transport path 11.

  That is, as shown in FIG. 1, each guide frame 39 is inclined so that the workpiece conveyance path 11 side is the front side (left side in FIG. 1). One end side (front end side) of each guide frame 39 is arranged so as to enter the work transport path 11 so as to cross the work transport path 11 diagonally, and is more than the work transport surface in the work transport path 11. Provided low. The other end side (rear end side) of each guide frame 39 is disposed at a position corresponding to the long workpiece W in contact with the stopper 31.

  As shown in FIG. 1, the plurality of guide frames 39 are provided at appropriate intervals in the front-rear direction (longitudinal direction of the work transport path 11) and in parallel with each other. Each guide frame 39 is provided with a pair of guide rails 41 (see FIGS. 5 and 6) extending from the one end side to the other end side. A slider 43 is supported on the guide rail 41 via a roller 45 so as to be able to reciprocate. In order to reciprocate the slider 43, each guide rail 41 is provided with reciprocating means 47.

  As an example of the reciprocating operation means 47, in the present embodiment, an endless chain 51 is hung on each chain sprocket 49 provided rotatably in the vicinity of both front and rear ends of each guide rail 41. A part of the endless chain 51 and a part of the slider 43 are appropriately connected. Therefore, the slider 43 is reciprocated along the guide rail 41 via the endless chain 51 by rotating the chain sprocket 49 forward and backward by the servo motor 57. The servo motor 57 may be an inverter motor system having a configuration in which a three-phase motor or the like is inverter-controlled and a position is detected by an encoder or the like.

  In order to synchronize and synchronize the reciprocating means 47 in each guide frame 39, an interlocking means 53 is provided. More specifically, as shown in FIG. 1, the chain sprocket 49 on the other end side of the guide frame 39 provided in the center portion in the front-rear direction and the chain sprocket 49 on the one end side in the rear guide frame 39 are connected to the connecting shaft 55A. It is linked and connected through. A chain sprocket 49 on one end side of the guide frame 39 in the central portion and a chain sprocket 49 on the other end side of the front guide frame 39 are interlocked and connected via a connecting shaft 55B. A chain sprocket 49 at an appropriate position is interlocked with the servo motor 57. The sliders 43 are arranged on a straight line parallel to the longitudinal direction of the workpiece conveyance path 11.

  With the above configuration, when the servo motor 57 is rotated forward and backward, the sliders 43 provided in the guide frames 39 are reciprocated synchronously. Further, by controlling the rotation of the servomotor 57, the sliders 43 can be positioned at desired positions along the guide rails 41.

  Note that the configuration of the interlocking means 53 that reciprocally moves the sliders 43 provided in the guide frames 39 is not limited to the configuration described above, and various configurations can be adopted.

  That is, when the endless chain 51 provided in each guide frame 39 is individually rotated by an individual servo motor, the servo motors can be configured to rotate synchronously. The sliders 43 are configured to reciprocate by a reciprocating device such as a fluid pressure cylinder. The reciprocating devices can be driven synchronously. The servo motor can also be driven synchronously by an inverter motor system having a configuration in which a three-phase motor or the like is inverter-controlled and the position is detected by an encoder or the like.

  In order to convey the workpiece W supported on the support frame 25 to the workpiece conveyance path 11, each slider 43 is provided with a workpiece receiving member 59 (see FIG. 6) that can move up and down. More specifically, the slider 43 is provided with a vertical operation device 61 such as a fluid pressure cylinder. The vertical operation device 61 is provided at the upper end of a vertical operation rod 61R such as a piston rod that can move up and down. The work receiving member 59 is provided. In order to keep the workpiece receiving member 59 always horizontal and move up and down, lifting rods 63 guided vertically to the slider 43 are provided on both sides of the moving direction with the vertical operating rod 61R in between. It is provided vertically.

  A plurality of large, medium, and small V-shaped workpiece support grooves 65 are provided on the upper surface of the workpiece receiving member 59 to stably support the workpieces W belonging to the large, medium, and small diameters. Yes. Therefore, it is possible to easily cope with workpieces W having different diameters.

  By the way, when the workpiece receiving member 59 is raised by the operation of the vertical operation device 61, the workpiece receiving member 59 is raised higher than the stopper 31 provided in the support frame 25 and the heel roller 17 provided in the workpiece conveyance path 11. Is. Therefore, the workpiece W on the support frame 25 can be lifted by the workpiece receiving member 59 and carried (conveyed) into the workpiece conveyance path 11.

  By the way, when the workpiece receiving member 59 carries the workpiece W on the support frame 25 into the workpiece conveying path 11, the workpiece receiving member 59 moves forward along the guide rail 41 inclined in the front-rear direction. Is. Here, the distance L1 in the front-rear direction when the workpiece receiving member 59 lifts the workpiece W on the support frame 25 and carries it into the workpiece conveyance path 11 is determined from the position of the positioning stopper 33 provided on the support frame 25. It is larger than the distance L2 in the front-rear direction over the holding region between the fixed vise jaw 9A and the movable vise jaw 9B in the feeding vise 3.

  Therefore, as described above, when the workpiece W on the support frame 25 is lifted by the workpiece receiving member 59 and loaded into the workpiece conveyance path 11, the front end portion (tip portion) of the workpiece W is fixed to the fixed vise jaw in the feeding vise 3. It is carried in between 9A and the fixed vise jaw 9B. Therefore, after carrying the workpiece W into the workpiece conveyance path 11, it is necessary to feed the material again by the support roller 13 in the workpiece conveyance path 11 so that the leading end of the workpiece W is positioned at the position of the feeding vise 3. Therefore, it is possible to improve the efficiency of the feeding operation.

  In addition, as described above, the front end portion of the workpiece W is directly carried between the fixed vise jaw 9A and the movable vise jaw 9B in the feeding vise 3, so that the feeding by the support roller 13 in the workpiece conveyance path 11 is performed. No material action is required. Therefore, the configuration for driving the support roller 13 can be omitted, and the configuration can be simplified.

  In the configuration as described above, when the workpiece W on the support frame 25 in the supply base 21 is lifted by the workpiece receiving member 59, the corresponding workpiece supporting groove 65 provided in the workpiece receiving member 59 corresponds to the diameter of the workpiece W. Positioning is performed so as to be positioned below the workpiece W. Then, by raising the workpiece receiving member 59, the workpiece W can be lifted in a state of being appropriately engaged with the workpiece support groove 65.

  Therefore, a series of operations for lifting the work W on the support frame 25 and transporting it onto the work transport path 11 and lowering the work W onto the work transport path 11 can be performed stably.

  As can be understood from the above description, according to the present embodiment, when the long work W on the supply table 21 is lifted by the work receiving member 59 and is transported onto the work transport path 11, the long work W is long. The workpiece W is held in a state parallel to the workpiece conveyance path 11. Then, the workpiece is conveyed obliquely forward so as to be close to the workpiece processing machine 1 positioned in front of the workpiece conveyance path 11 and conveyed to the workpiece conveyance path 11.

  Therefore, even if the interval between the workpiece processing machine 1 and the material supply base 21 is relatively large so that maintenance inspection is easy, The tip end portion of W is carried in closer to the workpiece processing machine 1. Therefore, the distance between the workpiece W on the workpiece conveyance path 11 and the workpiece processing machine 1 becomes shorter, and the workpiece W can be carried into the workpiece processing machine 1 in a shorter time. That is, the problem as described above can be solved.

  The present invention is not limited to the embodiment described above, and can be implemented in other forms by making appropriate changes. That is, in the above description, the configuration in which the workpiece W is pushed up from the lower side by the workpiece receiving member 59 has been described. However, a work clamp that is provided with a guide rail above the work conveyance path 11 and the material supply table 21 and can be lifted by holding the work W from above on a slider that is movable along the guide rail, or It is also possible to employ a configuration in which a fork that can enter and be lifted up under the workpiece W is provided so as to be movable up and down.
