Description

The present invention relates to a work processing apparatus.

A plate material chamfering device for chamfering a corner portion of a plate material as a work is known (see, for example, Patent Document 1).

Japanese Unexamined Patent Publication No. 2000-301442

In addition, chamfering may be performed on the corners of long workpieces such as shaped steel. Conventionally, chamfering to such a long work has been performed manually by a worker using a grinder. However, it is time-consuming and inefficient to manually chamfer a long workpiece. Therefore, for example, it is conceivable that the corner portion of the work is chamfered while the work made of shaped steel is fed in the longitudinal direction of the work. In this case, the chamfering grindstone may have a configuration in which the corner portion of the work is chamfered while the position is fixed, as in the configuration described in Patent Document 1. However, when chamfering is performed while feeding the work in the longitudinal direction of the long work, the grindstone is gradually scraped. Therefore, when the position of the grindstone is fixed as in the configuration described in Patent Document 1, the relative position between the grindstone and the corner portion changes, and the chamfering process is uniform over the entire longitudinal direction of the shaped steel. Cannot be applied to. Such a problem also exists in processing other than chamfering of shaped steel.

In view of the above circumstances, it is an object of the present invention to provide a work processing apparatus capable of processing a workpiece more evenly when processing a work such as a shaped steel.

That is, it is possible to maintain a state in which the elevating base 7 and the processing unit 9 can move in the movable direction D2 with a light force.

The 5-port valve 83 constitutes a part of the upstream actuator path 85 and a part of the downstream actuator path 86. The 5-port valve 83 has a port 101 connected to the supply path 82, an atmosphere open port 102, 103, and a solenoid valve 104, 105.

Further, by setting the air pressure P4 as the back pressure, the rod 67c of the actuator 67 can be lowered at an appropriate speed.

Next, the operation in the work processing apparatus 1 will be described. In FIGS. 7 to 9, the line to which compressed air is supplied from the air pressure source 81 is shown by a thick solid line, and the line of air from the elevating cylinder 5 and the actuators 47 and 67 is shown by a dotted line.

<When the work processing device 1 is in a standby state in which the work 200 is not processed>
As shown in FIG. 7, when the work processing apparatus 1 is in a standby state in which the work 200 is not processed, the rod 5c of the elevating cylinder 5, the rod 47c of the upstream actuator 47, and the rod 67c of the downstream actuator 67 are any of them. Is also arranged at the upper standby positions A1, A11, and A12. In order to make such an arrangement, in the elevating cylinder path 84, compressed air is supplied from the second path 93 to the downstream port 5e of the elevating cylinder 5. As a result, the piston 5b and the rod 5c of the elevating cylinder 5 are pushed up to the upper position in the cylinder case 5a. At this time, the upper port 5d of the elevating cylinder 5 is open to the atmosphere through the second path 93, the regulator 95, and the solenoid valve 91. Further, in the upstream actuator path 85, compressed air is supplied from the fourth path 112 to the lower port 47e of the actuator 47. As a result, the piston 47b and the rod 47c of the actuator 47 are pushed up to the upper position in the cylinder case 47a. Further, the upper port 47d of the actuator 47 is open to the atmosphere through the third path 111, the regulator 114, and the 5-port valve 83. With the above configuration, the swing member 45 of the upstream processing portion 35 and the grindstone 43 are maintained in a horizontal posture. Further, in the downstream actuator path 86, compressed air is supplied from the sixth path 122 to the lower port 67e of the actuator 67. As a result, the piston 67b and the rod 67c of the actuator 67 are pushed up to the upper position in the cylinder case 67a. Further, the upper port 67d of the actuator 67 is open to the atmosphere through the fifth path 121, the regulator 124, and the 5-port valve 83. With the above configuration, the swing member 65 of the downstream processing portion 36 and the grindstone 63 are maintained in a horizontal posture.

<When the work processing device 1 lowers the elevating base 7 to the processing position A2 in order to process the work 200, but is in a ready state where chamfering by the grindstones 43 and 63 is not performed>
As shown in FIG. 8, when in the ready state, the rod 5c of the elevating cylinder 5 is arranged at the machining position A2 below the standby position A1. On the other hand, the rod 47c of the upstream actuator 47 and the rod 67c of the downstream actuator 67 are still arranged at the upper standby positions A11 and A12. In order to make such an arrangement, in the elevating cylinder path 84, compressed air is supplied from the first path 92 to the upper port 5d of the elevating cylinder 5. As a result, the piston 5b and the rod 5c of the elevating cylinder 5 are pushed down to the lower position in the cylinder case 5a. At this time, the lower port 5e of the elevating cylinder 5 passes through the second path 93, the air operating valve 96, and the elevating cylinder return path 94, and the constant air pressure P2 is maintained by the regulator 97. As a result, the piston 5b and the rod 5c of the elevating cylinder 5 are arranged in a floating state at the machining position A2. The height of the machining position A2 in the movable direction D2, that is, the position of the rod 5c of the elevating cylinder 5 in the movable direction D2 is defined by appropriately setting the air pressures P1 and P2. In this way, the rod 5c of the elevating cylinder 5 is held at the machining position A2 in the movable direction D2 by the fluid pressures P1 and P2 supplied to the elevating cylinder 5. At this time, by setting the air pressure P1 <air pressure P2 (P2 is slightly larger than P1), the rod 5c of the elevating cylinder 5 receives the weight of the movable unit 10 including the processing unit 9, and the movable unit 10 is in a floating state. Can be maintained. That is, it is possible to maintain a state in which the elevating base 7 and the processing unit 9 can move in the movable direction D2 with a light force.

<When the work processing device 1 is in the processing state in which the work 200 is chamfered>
As shown in FIG. 9, when the work processing apparatus 1 is in the processing state in which the work 200 is being processed, the rod 47c of the upstream actuator 47 and the rod of the downstream actuator 67 are further added from the ready state shown in FIG. 67c are arranged at the lower processing positions A21 and A22, respectively. In order to make such an arrangement, in the upstream actuator path 85, compressed air is supplied from the third path 111 to the upper port 47d of the actuator 47. As a result, the piston 5b and the rod 5c of the actuator 47 are pushed down to the lower position in the cylinder case 5a. Further, the lower port 47e of the actuator 47 communicates with the fourth path 112 and the actuator return path 113, and the set pressure in the regulator 116 is maintained. With the above configuration, the swing member 45 of the upstream processing portion 35 and the grindstone 43 rotate around the fulcrum shaft 44 to change from the horizontal posture to the inclined posture. Further, in the downstream actuator path 86, compressed air is supplied from the fifth path 121 to the upper port 67d of the actuator 67. As a result, the piston 67b and the rod 67c of the actuator 67 are pushed down to the lower position in the cylinder case 67a. Further, the lower port 67e of the actuator 67 is connected to the sixth path 122 and the actuator return path 113, and the set pressure in the regulator 116 is maintained. With the above configuration, the swing member 65 of the downstream processing portion 36 and the grindstone 63 rotate around the fulcrum axis 64 to change from the horizontal posture to the inclined posture. As described above, the rods 47c and 67c are configured to pressurize the grindstones 43 and 63 toward the workpiece 202 side by the compressed air supplied to the actuators 47 and 67.

In this state, the work 200 is fed in the feed direction D1 by the transport roller 2. At this time, the work 200 first comes into contact with the roller 28 of the upstream guide 21, so that the heights (upper and lower positions) of the elevating base 7 and the processing unit 9 with respect to the work 200 in the movable direction are aligned. At this time, the elevating base 7 and the processing unit 9 move in the movable direction D2 by the contact between the roller 28 and the work 200. At this time, since the elevating cylinder 5 is floatingly supported by air pressures P1 and P2 from both sides in the movable direction D2, it can move in the movable direction D2 with a light force. That is, when the grindstones 43, 63 and the tool holders 42, 62 receive an external force from the work 200 in the movable direction D2, the transport guide mechanism 8 and the machining unit 9 move in the movable direction D2. Then, when the work 200 is fed in the feed direction D1, the rotating grindstones 43 and 63 come into contact with the workpiece 202, and the workpiece 202 is chamfered. At this time, by setting the air pressure P3> P4, the actuator 47 can maintain the state in which the grindstone 43 is strongly pressed against the workpiece 202 of the work 200. Similarly, by setting the air pressure P3> P4, the actuator 67 can maintain a state in which the grindstone 63 is strongly pressed against the workpiece 202 of the work 200.

When the grindstones 43 and 63 are worn in order from the outer peripheral portion due to chamfering, the rods 47c and 67c are moved downward by the compressed air supplied to the upper ports 47d and 67d of the actuators 47 and 67 as shown in FIG. By moving, the grindstones 43 and 63 can be moved around the fulcrum shafts 44 and 64. As a result, it is possible to suppress a change in the contact state between the grindstones 43 and 63 and the workpiece 202. The work 200 passes through the grindstones 43 and 63 along the feed direction D1 and then comes into contact with the roller 34 of the downstream guide. As a result, the heights (vertical positions) of the elevating base 7 and the processing unit 9 with respect to the work 200 in the movable direction are aligned. At this time, the elevating base 7 and the processing unit 9 move in the movable direction D2 by the contact between the roller 34 and the work 200. At this time, as described above, since the elevating cylinder 5 is floatingly supported by the air pressures P1 and P2 from both sides of the movable direction D2, it can move in the movable direction D2 with a light force.

When the work 200 passes through the roller 34 along the feed direction D1, the chamfering process to the workpiece 202 is completed. When the chamfering process to another work 200 is continued, the new work 200 passes in the order of the roller 28, the grindstones 43, 63, and the roller 34 along the feed direction D1. On the other hand, when the chamfering of the work 200 is completed, the work processing device 1 operates in the order of the ready state shown in FIG. 8 and the standby state shown in FIG. 7, and then the power of the work processing device 1 is turned off.

As described above, according to the present embodiment, the first support portions 41 and 61 of the upstream machining portion 35 and the downstream machining portion 36 are grindstones as the position of the workpiece 202 of the work 200 changes in the movable direction D2. Together with 43 and 63, the tool holders 42 and 62 are configured to be displaced in the movable direction D2. According to this configuration, the work 200 is fed in the longitudinal direction of the long work 200. Therefore, the position of the workpiece 202 in the movable direction D2 at the location where the grindstones 43 and 63 are arranged changes due to the running vibration of the work 200 and the influence of bending and warpage existing in the work 200. In response to such a position change, the positions of the grindstones 43, 63 and the elevating base 7 in the movable direction D2 can be moved by moving the floating cylinder rod 5c supported by floating. As a result, the work 200 can be chamfered by the grindstones 43 and 63 while the influence of bending and warpage existing in the work 200 is suppressed. Therefore, when the work 200 is machined, the workpiece 202 can be machined more evenly.

Further, according to the present embodiment, the rod 5c of the elevating cylinder 5 is held at the machining position A2 in the movable direction D2 by the fluid pressures P1 and P2 supplied to the elevating cylinder 5, and the grindstones 43, 63 and the tool holder 42. , 62 are configured to move in the movable direction D2 by receiving an external force in the movable direction D2. According to this configuration, since the rod 5c of the elevating cylinder 5 is floatingly supported by the air pressures P1 and P2, the grindstones 43 and 63 are automatically moved in the movable direction D2 according to the external force acting on the grindstones 43 and 63 from the work 200. Can be moved to.

Further, according to the present embodiment, the workpiece portion 202 of the work 200 includes the corner portion 201, and the tool holders 42 and 62 hold the grindstones 43 and 63 for cutting the corner portion 201. According to this configuration, the work processing apparatus 1 most suitable for chamfering the shaped steel can be realized.

Further, according to the present embodiment, the first support portions 41 and 61 of the upstream machining portion 35 and the downstream machining portion 36 are fulcrums corresponding to the swing members 45 and 65 during machining of the workpiece 202 of the work 200. It is configured to be displaceable around the shafts 44 and 64. Then, the actuators 47 and 67 of the first support portions 41 and 61 generate a pressing force around the fulcrum shafts 44 and 64 that press the grindstones 43 and 63 against the workpiece 202. According to this configuration, chamfering is performed by the grindstones 43 and 63 while feeding the work 200 in the longitudinal direction of the long work 200, so that the grindstones 43 and 63 are gradually scraped. Therefore, the tool holders 42, 62 and the grindstones 43, 63 rotate around the fulcrum shaft 44 as the grindstones 43, 63 wear, so that the grindstones 43, 63 can be moved to the work 200 regardless of the amount of wear of the grindstones 43, 63. It can continue to be pressed against the workpiece 202. Therefore, it is possible to suppress the change in the contact state between the grindstones 43 and 63 and the workpiece 202, and the chamfering process can be performed evenly over the entire longitudinal direction of the work 200. Therefore, when the work 200 is machined, the workpiece 202 can be machined more evenly.

Further, according to the present embodiment, the actuator 47 of the upstream processing portion 35 and the actuator 67 of the downstream processing portion 36 correspond to each other by moving the rods 47c and 67c of the actuators 47 and 67 in the axial direction, respectively. The holders 42 and 62 are swung in the directions around the fulcrum shafts 44 and 64. Then, the rods 47c and 67c pressurize the grindstones 43 and 63 toward the workpiece 202 side by the air pressures P3 and P4 supplied to the actuators 47 and 67. According to this configuration, the grindstones 43 and 63 can be arranged at appropriate positions by supplying the air pressures P3 and P4 to the actuators 47 and 67.

Further, according to the present embodiment, the roller 28 of the transport guide mechanism 8 guides the work 200 transported in the feed direction D1, and by receiving the work 200, the position with respect to the work 200 can be changed along the movable direction D2. is there. Further, the tool holders 42 and 62 and the grindstones 43 and 63 are arranged on the downstream side of the roller 28 in the feed direction D1 and are configured to be displaceable in conjunction with the roller 28 in the movable direction D2. In the present embodiment, the long work 200 is chamfered while being fed in the longitudinal direction of the work 200, and there is a large or small shape error in the shape of the work 200. Further, when chamfering is performed while feeding the work 200 at a high speed, the work 200 may be displaced in the movable direction D2 with respect to the grindstones 43 and 63. Even under such conditions, when the roller 28 comes into contact with the work 200, the grindstones 43 and 63 can move in the movable direction D2 together with the roller 28 and the elevating base 7. Therefore, the relative positions of the work 200 and the grindstones 43 and 63 in the movable direction D2 can be made constant by the operation of the roller 28, the elevating base 7, the elevating cylinder 5, and the like. As a result, it is possible to prevent the work 200 from coming into contact with a portion other than the outer peripheral surface (grinding surface) of the grindstones 43 and 63, and it is possible to suppress damage to the grindstones 43 and 63. That is, when the work 200 is processed, damage to the grindstones 43 and 63 can be suppressed more reliably.

Further, according to the present embodiment, the roller 34 of the transport guide mechanism 8 is arranged on the downstream side of the tool holders 42, 62 and the grindstones 43, 63 in the feed direction D1 and receives the work 200 transported in the feed direction D1. The position with respect to the work 200 can be changed along the movable direction D2. According to this configuration, the rollers 28 and 34 arranged at two locations separated from each other in the feed direction D1 can come into contact with the work 200. As a result, it is possible to prevent the entire movable unit 10 including the rollers 28, 34 and the elevating base 7 from being tilted with respect to the feed direction D1 by receiving the force from the work 200. Therefore, the movable unit 10 can be smoothly moved in the movable direction D2.

Further, the rollers 28 and 34 and the work 200 are configured to be in rolling contact with each other. According to this configuration, the rollers 28 and 34 can smoothly feed the work 200 in the feed direction D1 with a small contact resistance.

Further, according to the present embodiment, in the work processing apparatus 1, a sensor for detecting the position of the rod 5c of the elevating cylinder 5, the position of the rods 47c and 67c of the actuators 47 and 67, and the position of the grindstones 43 and 63. Is unnecessary. Further, the work processing apparatus 1 does not require a servo mechanism for controlling the positions of the grindstones 43 and 63 and the elevating base 7. Further, in the pneumatic circuit 80, only a manual switch for turning on / off each of the solenoid valves 91, 104, 105 is provided. In this way, machining of the work 200 in the work machining device 1 can be realized at low cost without using an expensive position control mechanism (for example, feedback control or feedforward control).

Although the case of processing the work 200 has been described in the above description, the work processing device 1 can also be used for processing a work other than the work 200. For example, as shown in FIG. 11, the work processing apparatus 1 may be used for processing the work 200A having a height higher than that of the work 200 in the laid-down state. The difference between the height of the work 200 from the transfer roller 2 and the height of the work 200A from the transfer roller 2 is a difference Δ, for example, a dozen mm. In the machining state when the work processing device 1 chamfers the work 200A, the height position of the piston 5b of the elevating cylinder 5 is the piston 5b in the machining state when the work processing device 1 chamfers the work 200. It is located above the height of the above difference Δ. In this case, when the work 200A comes into contact with the roller 28, an upward force acts on the roller 28. This force is transmitted to the rod 5c and the piston 5b of the elevating cylinder 5 via the elevating base 7. As described above, the piston 5b is floatingly supported by the air pressures P1 and P2, so that the piston 5b moves upward while discharging the working air from the upper port 5d of the cylinder case 5a. Then, when the piston 5b moves upward to a height at which the height position of the roller 28 coincides with the height position of the workpiece 202A of the work 200A, the movement of the piston 5b is stopped.

As is clear from the configuration described with reference to FIG. 11, the height position of the special grindstones 43 and 63 is adjusted for any of the workpieces 200 and 200A having different heights from the transport roller 2. Chamfering can be performed without. That is, the difference in height of the workpieces 202 and 202A from the transport roller 2 can be dealt with by changing the position of the rod 5c of the elevating cylinder 5. On the other hand, the wear of the grindstones 43 and 63 can be dealt with by changing the positions of the rods 47c and 67c of the actuators 47 and 67. In this way, by separately providing the elevating cylinder 5 for dealing with the size of the work and the actuators 47 and 67 for dealing with the wear of the grindstones 43 and 63, each function can be more reliably exhibited. ..

Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. The present invention can be modified in various ways as described in the claims.

The present invention can be widely applied as a work processing apparatus.
