Furthermore, other objects, features and advantages of the present invention will be apparent from the following description of the embodiments of the present invention related to the attached drawings.

Hereinafter, embodiments of the present invention will be described with reference to the drawings, but the present invention is not limited to these embodiments.

Referring to FIG. 1 , a processing line system 101 as an embodiment of the present invention will be described. The processing line system 101 includes a processing device 102 such as a pressing device for processing a sheet 105 such as a coil, a sheet feeding device (feeder) 103 for intermittently conveying the sheet 105 from an unwinding feeder to the processing device 102, and a sheet cutting device 104 having a cutter for cutting the sheet 105 processed in the processing device 102. The sheet 105 may be taken out from the unwinding feeder and fed to the sheet feeding device 103 through a sheet feeding device (stock controller) for correcting and flattening the sheet 105. Furthermore, the processing production line system 101 has a control device 106 for controlling the processing device 102, the plate feeding device 103, and the plate cutting device 104. The plate feeding device 103 may also be provided with a pair of rollers, a motor for driving at least one of the pair of rollers to rotate, and a control device for controlling the motor. The control device of the plate feeding device 103 may also be a control device for controlling the intermittent transport of the plate 105 toward the processing device 102 by holding the plate 105 on the pair of rollers, or by separating the pair of rollers to release the plate 105. However, the plate feeding device 103 is not limited thereto. Furthermore, the control device of the plate feeding device 103 may also be built into the control device 106.

The plate cutting device 104 can drive the cutter in response to the process of the processing device 102 on the plate 105. The process of the processing device 102 includes a process of moving the plate 105 in response to the target length by the plate feeding device 103 and a process of processing the moved plate 105. The plate cutting device 104 can drive the cutter in response to the process of processing the plate 105 during the period from the end of the process of moving the plate 105, to the start of the process of processing the plate 105 again. For example, when the processing device 102 is a pressing device, the pressing device may also include a crank shaft 107, an upper mold 109, a lower mold 110, a motor for driving the crank shaft 107 to rotate, and a control device for controlling the motor. Alternatively, after the process of moving the plate 105, the control device of the pressing device may control the motor to drive the crank shaft 107 provided with an eccentric cam to rotate during the process of pressing the plate 105, thereby moving the upper mold 109 engaged with the eccentric cam toward the upper and lower sides in the straight direction, and performing pressing on the moved plate 105 through the cooperation of the upper mold 109 and the lower mold 110. Furthermore, after the process of pressing the plate 105, the plate feeding device 103 may be used to move the plate 105 again in accordance with the target length. However, the processing device 102 is not limited thereto. Furthermore, the control device of the processing device 102 may be built into the control device 106. The plate cutting device 104 may drive the cutter in accordance with the process of pressing the plate 105 during the period from the end of the process of moving the plate 105, through the process of pressing the plate 105, to the start of the process of pressing the plate 105 again.

The conveying action of the plate 105 performed by the plate feeding device 103 is intermittently performed in a manner of repeatedly moving the plate 105 forward and stopping in coordination with the processing in the processing device 102. The plate cutting device 104 can drive the cutter in response to the intermittent conveyance of the plate 105 performed by the plate feeding device 103. FIG. 2A shows an example of the action relationship of the processing device 102, the plate feeding device 103, and the plate cutting device 104 in one cycle of the process of the processing device 102. In particular, in the case where the processing device 102 is a pressing device, an example of the action relationship when using mold A as an example of the upper mold 109 and the lower mold 110 is shown. The angle (°) shown in FIG. 2A indicates the rotation angle of the crankshaft 107. When the crankshaft 107 rotates from 270° to 0° to 90°, it indicates a process in which the plate 105 is moved according to the target length by the plate feeding device 103. Furthermore, when the crankshaft 107 rotates from 90° to 180° to 270°, it indicates a state in which the plate 105 being transported toward the processing device 102 by the plate feeding device 103 is stopped. When the crankshaft 107 rotates to 180°, it indicates a process in which the moved plate 105 is processed. When the crankshaft 107 rotates from 270° to 0° to 90°, that is, in the case of a process in which the plate 105 is moved by the plate feeding device 103, the plate cutting device 104 is in the process of stopping the drive of the cutter. Moreover, when the crankshaft 107 rotates from 90° to 180° to 270°, that is, in the case of a process including processing the plate 105, the plate cutting device 104 is in the process of driving the cutter. Furthermore, the plate cutting device 104 may start driving the cutter when the rotation angle of the crank shaft 107 is 90°, that is, when the conveyance of the plate 105 by the plate feeding device 103 stops, in order to cut the plate 105 that has been processed in the processing device 102, and stop driving the cutter when the rotation angle of the crank shaft 107 is 270°, that is, when the conveyance of the plate 105 by the plate feeding device 103 starts.

FIG2B shows another example of the motion relationship among the processing device 102, the plate feeding device 103, and the plate cutting device 104 in one cycle of the process of the processing device 102. In particular, when the processing device 102 is a pressing device, another example of the motion relationship is used when a mold B different from the mold A is used as another example of the upper mold 109 and the lower mold 110. The angle (°) shown in FIG2B represents the rotation angle of the crankshaft 107. When the crankshaft 107 rotates from 240° to 0° to 120°, it represents a process in which the plate feeding device 103 moves the plate 105 according to the target length. Furthermore, when the crankshaft 107 rotates from 120° to 180° to 240°, it indicates that the sheet 105 being transported toward the processing device 102 by the sheet feeding device 103 is stopped, and when the crankshaft 107 rotates to a periphery of 180°, it indicates that the moved sheet 105 is being processed. When the crankshaft 107 rotates from 240° to 0° to 120°, that is, in the process of moving the sheet 105 by the sheet feeding device 103, the sheet cutting device 104 is in the process of stopping the drive of the cutter. When the crankshaft 107 rotates from 120° to 180° to 240°, that is, when the process includes processing the plate 105, the plate cutting device 104 is in the process of driving the cutter. In addition, the plate cutting device 104 may start driving the cutter to cut the plate 105 processed by the processing device 102 when the crankshaft 107 rotates at an angle of 120°, that is, when the plate 105 conveyed by the plate feeding device 103 stops, and stop driving the cutter when the crankshaft 107 rotates at an angle of 240°, that is, when the plate 105 conveyed by the plate feeding device 103 starts.

Comparing FIG. 2A and FIG. 2B , the rotation angle of the crankshaft 107 during the process of moving the plate 105 by the plate feeding device 103 is 180° in FIG. 2A , while it is 240° in FIG. 2B . When the amount of plate 105 transported per unit time by the plate feeding device 103 is the same, the plate feeding device 103 can transport a larger amount of plate 105 in the case of FIG. 2B than in FIG. 2A . Furthermore, the rotation angle of the crankshaft 107 during the process of processing the plate 105 is 180° in FIG. 2A , while it is 120° in FIG. 2B . The plate cutting device 104 is in a process of stopping the drive of the cutter when the plate 105 is moved by the plate feeding device 103 (in the case of FIG. 2A , the rotation angle of the crank shaft 107 is 180°, and in the case of FIG. 2B , the rotation angle of the crank shaft 107 is 240°). Moreover, the plate cutting device 104 is in a process of driving the cutter when the process includes processing the plate 105 (in the case of FIG. 2A , the rotation angle of the crank shaft 107 is 180°, and in the case of FIG. 2B , the rotation angle of the crank shaft 107 is 120°). Furthermore, when the rotation angle of the crank shaft 107 during the process of moving the plate 105 by the plate feeding device 103 is 120°, the plate feeding device 103 can transport a smaller amount of plate 105 compared to Figure 2A, and the plate cutting device 104 is in the process of stopping the drive of the cutter when the plate 105 is moved by the plate feeding device 103, that is, when the rotation angle of the crank shaft 107 is 120°, and is in the process of driving the cutter when the process includes processing the plate 105, that is, when the rotation angle of the crank shaft 107 is 240°. In this way, the mold used in the pressing device can be coordinated with the rotation angle of the crank shaft 107 to adjust the amount of plate 105 transported by the plate feeding device 103 toward the processing device 102. Furthermore, the plate cutting device 104 can be used to cut the plate 105 that has been processed in the processing device 102.

Furthermore, the crankshaft 107 may be rotated faster or slower depending on the rotation angle. For example, in FIG. 2A , the crankshaft 107 may be rotated faster when rotating from 270° to 0° to 90°, so that the time for conveying the plate 105 to the processing device 102 is shorter and the conveying amount of the plate 105 to the processing device 102 is smaller. On the other hand, the crankshaft 107 may be rotated slower when rotating from 90° to 180° to 270°, and the plate cutting device 104 drives the cutter to cut the plate 105 processed by the processing device 102. Alternatively, the crank shaft 107 may be rotated more slowly when rotating from 270° through 0° to 90°, so that the time for transporting the plate 105 to the processing device 102 is longer and the amount of plate 105 transported to the processing device 102 is greater. On the other hand, the crank shaft 107 may be rotated more quickly when rotating from 90° through 180° to 270°, during which the plate cutting device 104 drives the cutter to cut the plate 105 that has been processed in the processing device 102.

As shown in FIG. 3A to FIG. 3C , the plate cutting device 104 may also include a housing 201, a cutter housed in the housing 201, a driving unit partially housed in the housing 201 and used to drive the cutter, and a control device for controlling the driving unit. The driving unit may also include a shaft 202 that can rotate around a rotation axis 203, a first motor 204 connected to one end of the shaft 202, and a mechanism for causing the cutter to reciprocate in one direction as the shaft 202 rotates around the rotation axis 203. The driving unit may also include a second motor 209 connected to the other end of the shaft 202 in order to suppress the torsion of the shaft 202. The cutter may be a waste material cutter composed of a first cutting blade 205 fixed to the housing 201 and a second cutting blade 206 that cooperates with the first cutting blade 205 to cut the plate 105. The mechanism may also include a cam 207 fixed to the shaft 202. When the shaft 202 rotates around the rotation axis 203, the cam 207 may cause the second cutting blade 206 to reciprocate relative to the first cutting blade 205 along with the rotation. Moreover, the second cutting blade 206 will approach the first cutting blade 205, and when the first cutting blade 205 and the second cutting blade 206 are engaged, the plate 105 conveyed from the outside through the inlet 208 arranged in the housing 201 will be cut. The cam 207 can also be a flat cam with a special contour curve, a plane cam with a special groove, etc., or it can be, for example, a circular plate cam with an eccentric circular plate, a triangular cam, etc. The cam 207 can be any shape as long as it can rotate around the rotation axis 203 from the shaft 202 to achieve the required reciprocating motion of the second cutting blade 206. However, the plate cutting device 104 is not limited to this. Moreover, the control device of the plate cutting device 104 can also be built in the control device 106.

The shaft 202 can rotate in response to the process of the processing device 102 on the plate 105. The shaft 202 can rotate in response to the process of processing the plate 105 during the period from when the process of moving the plate 105 is completed, the process of processing the plate 105 is passed, and the process of processing the plate 105 again begins. The control device of the plate cutting device 104 can also be a control device that controls the first motor 204 to drive the shaft 202 fixed with the cam 207 to rotate in response to the process of processing the plate 105, so that the second cutting blade 206 engaged with the cam 207 reciprocates in the direction of the first cutting blade 205, and the plate 105 that has been processed in the processing device 102 is cut by the engagement of the first cutting blade 205 and the second cutting blade 206.

The shaft 202 can change its rotation speed in response to the process of the processing device 102 on the plate 105. The shaft 202 can also change its rotation speed to make the rotation speed faster when the process of moving the plate 105 is completed, and to make the rotation speed slower when the process of processing the plate 105 again starts. The shaft 202 can also stop rotating during the process of moving the plate 105, and can also start rotating when the process of moving the plate 105 is completed. In addition, the shaft 202 can change its rotation speed in response to the rotation angle of the shaft 202. The shaft 202 may also rotate at a slower rotation speed within a predetermined rotation angle in a process of moving the plate 105, and rotate at a faster rotation speed within another predetermined rotation angle in a process of processing the plate 105. Furthermore, the shaft 202 may change the rotation speed during one cycle of the process of the processing device 102 on the plate 105 so as to rotate once around the rotation axis 203. Even if the shaft 202 rotates at a relatively slow rotation speed within a predetermined rotation angle in the process of moving the plate 105, and rotates at a relatively fast rotation speed within another predetermined rotation angle in the process of processing the plate 105, the rotation speed can be changed so that the time for the shaft 202 to rotate once around the rotation axis 203 coincides with the time for one cycle of the process of the processing device 102 for the plate 105. In addition, the shaft 202 can also change the rotation speed so that it rotates once around the rotation axis 203 in a period that is an integer multiple of one cycle of the process of the processing device 102 for the plate 105. In this case, the cam 207 may be a cam having a shape of the vertex that is a multiple of the integer. For example, when the shaft 202 rotates once around the rotation axis 203 during a period that is three times the period of one cycle of the processing of the plate 105 by the processing device 102, the cam 207 may be a triangular cam. When the portion near the vertex of the cam 207 is engaged with the second cutting blade 206, the first cutting blade 205 and the second cutting blade 206 are engaged to cut the plate 105 that has been processed in the processing device 102.

The processing device 102 may also be equipped with a sensor for detecting the process of the processing device 102. For example, when the processing device 102 is a pressing device, an angle detector 108 such as an encoder for detecting the rotation angle of the crank shaft 107 may be provided as a sensor. The rotation angle of the crank shaft 107 shown in FIG. 2A and FIG. 2B is detected by the angle detector 108. In addition, the output signal of the rotation angle detected by the angle detector 108 is sent to the control device 106. In this way, the control device 106 can recognize the process of the processing device 102. For example, as shown in FIG. 2A , when the rotation angle of the crankshaft 107 is between 0° and 90° from 270°, the control device 106 can recognize that the process is in which the plate 105 is moved by the plate feeding device 103 according to the target length. Furthermore, when the rotation angle of the crankshaft 107 is around 180°, the control device 106 can recognize that the process is in which the moved plate 105 is processed. When the control device 106 recognizes that the rotation angle of the crankshaft 107 is 90°, the plate feeding device 103 stops the conveyance of the plate 105 to the processing device 102. Furthermore, when the control device 106 recognizes that the rotation angle of the crank shaft 107 is 270°, the plate feeding device 103 is controlled to start the conveyance of the plate 105 toward the processing device 102 again, and the plate 105 is conveyed toward the processing device 102 at a certain speed. In this way, the control device 106 can control the plate feeding device 103 to convey the plate 105 toward the processing device 102 intermittently in response to the output signal from the angle detector 108.

When the control device 106 recognizes that the rotation angle of the crank shaft 107 is between 270° and 0° and 90°, that is, when the plate feeding device 103 is in the process of moving the plate 105 according to the target length, the plate cutting device 104 stops driving the cutter. When the control device 106 recognizes that the rotation angle of the crank shaft 107 is between 90° and 180° and 270°, that is, when the process includes processing the plate 105, the plate cutting device 104 drives the cutter. When the control device 106 recognizes that the rotation angle of the crank shaft 107 is 90°, the plate cutting device 104 starts driving the cutter to cut the plate 105 that has been processed by the processing device 102. Furthermore, when the control device 106 recognizes that the rotation angle of the crank shaft 107 is 270°, the drive of the cutter of the plate cutting device 104 ends. In this way, the control device 106 can drive the cutter of the plate cutting device 104 to cut the plate 105 that has been processed by the processing device 102 in response to the output signal from the angle detector 108.

By using the processing production line system 101 of the present invention as described above, the processing device 102 such as a pressing device can perform processing such as pressing on the plate 105 that is conveyed intermittently from the plate feeding device 103 with high precision, thereby manufacturing small parts for information-related devices such as mobile phones and personal computers, automobile and industrial motor parts, and components of home appliances. In addition, the plate cutting device 104 can cut the plate 105 that has been processed by the pressing device 102 at an appropriate timing, thereby improving production efficiency.

The above description is made with respect to specific embodiments, but the present invention is not limited thereto. It is clear to those skilled in the art that various changes and modifications can be made within the scope of the principles of the present invention and the scope of the attached patent applications.
