Description

[Technical Field]

[0001] The present invention relates to a real-time correction device for a spring processing machine that detects and corrects the processing of a spring processing machine that produces coil springs by twisting metal wire material in real time. [Background technology]

[0002] Coil springs are usually made by twisting metal wire material into a coil using a spring processing machine, but as described in Patent Document 1, for example, the spring processing machine is configured to bend the wire material output at high speed into a curved shape by guiding its output direction with two bending means, and to arrange the bent wire material into a coil shape with a pitch adjustment means, and then cut out a coil of a specified length to produce a coil spring. Because this processing is performed on the wire material output at high speed, if the bending means and pitch adjustment means are not controlled quickly, there is a problem of a decline in the quality of the finished coil spring.

[0008] 1 to 3 show an embodiment of a real-time correction device for a spring processing machine according to the present invention.

[0009] As shown, this embodiment comprises a holding frame 1, a sensor means 2 attached to the holding frame 1, an analysis means 3 signally connected to the sensor means 2, and two lighting units 4 attached to the holding frame 1.

[0010] In this embodiment, the holding frame 1 has a lower plate 11, a plurality of casters 12 attached to the underside of the lower plate 11 and in contact with the ground, thereby allowing the lower plate 11 to move relative to the ground through their rolling motion, two sensor holding members 13 each arranged at the upper end of a holding column 110 extending upward from the lower plate 11, a connecting member 14 extending upward from the lower plate 11, and spring receiving means 15 arranged between each sensor holding member 13 and the connecting member 14.

[0011] The spring receiving means 15 is configured to include a supporter 151 extending upward from the lower plate 11, a fine-adjustment cylinder 153 attached to the supporter 151 and configured to be extendable and retractable, and a spring receiving section 154 attached to the fine-adjustment cylinder 153 and whose vertical position can be adjusted according to the extension and retraction of the fine-adjustment cylinder 153. The spring receiving section 154 is adjacent to the spring processing machine 5 when the holding frame 1 moves adjacent to the spring processing machine 5, and includes a first receiving tray 156 and a second receiving tray 155 held by the fine-adjustment cylinder 153 and arranged sequentially in a direction away from the spring processing machine 5, with the second receiving tray 155 being configured so that its inclination in the vertical direction is greater than that of the first receiving tray 156. With this configuration, the coil spring cut out after processing by the spring processing machine can be first received by the first receiving tray 156 and then discharged via the second receiving tray 155.

[0012] The sensor means 2 has a detection unit 21 attached to each of the two sensor holding members 13, and a determination unit 22 connected to the detection unit 21 in terms of signals. The detection unit 21 can be configured using, for example, an image sensor, and the determination unit 22 can be configured using a processor that can collectively process the information output from the detection unit 21 and output a corresponding determination signal.

[0013] The analysis means 3 is connected to the judgment unit 22 via signals and has a database 31 in which multiple correction data associated with the judgment signal output by the judgment unit 22 is stored, so that when a judgment signal is received from the judgment unit 22, correction data corresponding to the received judgment signal can be output from the database 31. For example, a microcomputer or the like can be used as the analysis means 3.

[0014] The lighting unit 4 is attached to a corresponding connecting member 14 so as to support the detection performed by the sensor means 2, and is attached to the holding frame 1 via the connecting member 14.

[0015] As shown in FIGS. 4 to 6, the real-time correction device for the spring processing machine of this embodiment has casters 12, so that the holding frame 1 can be moved to an appropriate position next to the corresponding spring processing machine 5.

[0016] The spring processing machine 5 is equipped with material supply means 51 that supplies the metal wire material to be made into a spring along a predetermined supply direction B, pitch adjustment means 52 that adjusts the pitch of the coil A made into a spring from the wire material, a plurality of bending means 53 that adjust the diameter of the bent coil A, and control means 54 that controls the movement of the pitch adjustment means 52 and each bending means 53. With this configuration, the wire material output at high speed by the material supply means 51 is bent into a curved shape by guiding its output direction with the two bending means 53, and the bent wire material is then adjusted into coil A by the pitch adjustment means 52, and the coil A is cut to a predetermined length to be made into a coil spring.

[0017] 6, the specific configuration of the pitch adjustment means 52 in the spring processing machine 5 includes a motor 521, a worm 522 that is rotationally driven by the motor 521, a connecting arm 523 that is attached to the worm 522 and driven by the worm 522 that rotates, and that can move along the extension direction of the worm 522, and two pitch blades 524 that are attached to the connecting arm 523 and are arranged to extend opposite each other. With this configuration, by moving the connecting arm 523 with the driving force from the motor 521, each pitch blade 524 can move along the pitch direction C, which is the extension direction of the worm 522 and is perpendicular to the feed direction B.

[0018] 1, 4, and 5, each detection unit 21 of the sensor means 2 faces the spring processing machine 5 and performs detection toward the coil A being processed by the spring processing machine 5, so that it detects, for example, the pitch of multiple portions of the coil A or the diameter at which the coil A is bent, and outputs multiple corresponding detection results to the determination unit 22. The determination unit 22 receives information (such as the pitch or diameter) about the multiple portions of the coil A from the detection unit 21, generates one determination signal corresponding to this multiple information, and outputs it to the analysis means 3. When the analysis means 3 receives the determination signal from the determination unit 22, it finds correction data corresponding to the received determination signal from the database 31 and transmits it to the control means 54 of the spring processing machine 5. The control means 54 of the spring processing machine 5 controls the pitch adjustment means 52 and each bending means 53 based on the correction data received from the analysis means 3.

[0019] Therefore, the judgment unit 22 and the analysis means 3 in the real-time correction device for a spring processing machine of the present invention are both configured to output predetermined corresponding information in response to the received information (detection result or judgment signal), so that correction data can be provided to the control means 54 of the spring processing machine 5 in real time during processing by the spring processing machine without wasting time on calculations, thereby contributing to maintaining the quality of the finished coil springs.

[0020] Although the embodiment of the present invention has been described above, the present invention is not limited to this, and various modifications are possible without departing from the spirit of the present invention. [Explanation of symbols]
