The present invention relates to a wire supply shock absorber for supplying a wire to a cutting machine for cutting a wire to a certain length in order to produce a wiring harness only for a power supply and a signal transmission device such as an automobile.

Wiring harnesses, which are generally used as power supplies and signal transmission devices for automobiles, are produced by a number of processes such as wire cutting, crimping, and final assembly.

At this time, the most essential component for producing a wiring harness can be called a wire (wire), such a wire, it is required to vary the thickness and length, etc. In particular, the terminal is cut to the appropriate length through a cutting process It is required to be sent to the pressing process.

On the other hand, since the cutting machine is used to cut the wire in this way, the wire wound into the wound shape is supplied to the cutting machine by the wire supply shock absorber.

In this case, the above-described wire supply shock absorber is typically connected directly to the cutting machine to operate in conjunction with it. Therefore, the wire supply shock absorber applied to one cutting machine cannot be used for other cutting equipment, that is, there is a problem of incompatibility. In particular, the long-term use requires maintenance of the machine, which reduces productivity. Etc.

The present invention was created in order to solve such a conventional problem, and can be operated independently and can be applied to various cutting machines to improve compatibility, and in particular, to operate by applying a physical phenomenon, It is an object of the present invention to provide a wire feed washer device which can improve productivity because no maintenance is required.

In order to achieve the above object, the wire supply shock absorber according to the present invention is provided with a plate-shaped base and one side of the base to feed the wire to the cutting machine, and feeding means for transferring the wire to the cutting machine. And a tangle preventing means for preventing a tangle of wires conveyed by the feeding means, wherein the wires are provided by the feeding means between the tangle preventing means and the cutting machine. It is characterized by providing a cushioning means for maintaining a constant feed amount.

Such a characteristic configuration and the resulting effects of the present invention will become more apparent from the following detailed description of the invention with reference to the accompanying drawings.

1 is a perspective view conceptually showing a wire supply shock absorber according to the present invention, FIG. 2 is a perspective view showing an excerpt of the shock absorbing means, and FIG. 3 is an enlarged perspective view of an excerpt of FIG. 4 is a cross-sectional view taken along the line A-A of FIG. 3, and FIGS. 5 and 6 are a perspective view and a plan view showing an extraction of the feeding means.

As shown therein, the wire supply shock absorber according to the present invention includes a base 20 on a plate, a tangle preventing means 30, and a large plate for supplying the wire W to the cutting machine 10. The feeding means 40 and the buffer means 50 are roughly divided.

The aforementioned tangle preventing means 30 is installed so that the wire W wound on the spool in the process of transferring the wire W is transported without twisting, and the structure of the wire 9W is wound on the skein. A reel stand 31 is positioned, and above the reel stand 31, a disc 32 having a hole 32a through which the wire W can be guided is located. The guide plate 33 having the guide groove 33a through which the wire W can be guided, as well as supporting the disc 32, is fixedly installed on the upper surface of the base 10 through the frame 34. .

If the wire W is entangled in the middle of being transferred through the hole 32a, the disc 32 is pushed to operate the limit 32b fm mounted on the top of the disc 32 to automatically operate the cutting machine 10. Stop it.

Transfer feeding means 40 is provided on one side of the base 20 to transfer the wire (W) to the cutting machine 10, the auxiliary base 42 is supported by the frame 41 on one side of the base On one side of the auxiliary base 42, an annular guide groove 43a through which the wire W can be guided is formed on the outer circumferential surface thereof, and the wheel 43 is pivotally supported by rotation.

Meanwhile, a feeding motor 44 is fixedly installed on a lower surface of the auxiliary base 42, and a rotation shaft of the feeding motor 44 protrudes upward from the auxiliary base 42, and the guider 45 is provided on the rotation shaft. ) Is axially supported. In addition, the movable block 46 is pivotally supported on the auxiliary base 42 in a position adjacent to the guider 45. In particular, the movable block 46 is adjacent to the guider 45 and is disposed on the outer circumferential surface thereof. The auxiliary guider 47 in which the annular guide groove 47a is formed is rotatably installed. At this time, the movable block 46 is elastically supported toward the side on which the guider 45 is installed by the spring S fixed at both ends of one side of the movable block 46 and one side of the auxiliary base 42.

In addition, a fixed block 48 is fixedly installed at one end of the auxiliary base 42 adjacent to the shock absorbing means described later, and the fixed block 48 has a wire passing between the guider 45 and the auxiliary guider 47 ( Guide grooves 48a are formed to penetrate so that W) can be inserted and guided.

The provision of the buffer means between the feeding means 40 and the cutting machine 10 described above is such that the wire W is supplied by the feeding means 40 and in particular by the cutting machine 10 with a predetermined tensile force. Because it is pulled. Therefore, only when the feeding amount of the wire W supplied from the feeding means 40 and the pulling force in the cutting machine 10 are properly balanced, the transfer of the wire W is performed smoothly, especially on the wire W. This is because it is possible to appropriately prevent breakage or sagging.

In the structure of the shock absorbing means 50 having such an effect, the left and right support frames 51 and 52 are fixedly installed on the base 20 so as to face each other, and the left and right support frames 51 and 52 are fixed. Guide grooves (51a, 52a) are formed in communication with the side. An upper frame 53 is connected across the upper ends of the left and right support frames 51 and 52, and a support bracket 54 is extended to a lower portion of the center of the upper frame 53. In addition, a pulley set 55 having an annular groove (not shown) formed on the outer circumferential surface thereof is rotatably coupled to the support bracket 54.

Meanwhile, the guide grooves 51a and 52a of the left and right support frames 51 and 52 have substantially the same shape as the above-mentioned pulley 55, that is, the left and right guides in which the annular grooves 56a and 57a are formed. Weights 56 and 67 are built in. In this case, the left and right guide weights 56 and 57 are installed in the left and right support frames 51 and 52 as their center bodies 56b and 57b are installed as shown in FIG. It is installed so as to slide downward, and in particular, its outer circumferential surface is provided to expose a predetermined length to the outside of the guide grooves 51a and 52a.

The weights of the two left and right guide weights 56 and 57 are preferably different from each other. That is, it is preferable to form the guide weight 56 of the side adjacent to the cutting machine 10 relatively heavy. This is because the left and right guide weights 56 and 57 are moved by the force pulled from the cutting machine 10 because the upper and lower guide weights 56 and 57 are pulled to the left guide weight 56 located at a short distance therefrom. This is because more force is applied.

Therefore, in order to operate the guide weights 56 and 57 to work effectively, the weight of the cutting machine 10 and the guide weights 56 located at a short distance must be made more heavy so that the upper and lower transfers are linked to it. This is because the right guide weight 57 can be balanced with each other.

On the other hand, the amount of movement of the left and right guide weights 56 and 57 in the frame on either side of the left and right support frames 51 and 52, that is, on the right frame 52 adjacent to the feeding motor 44 as shown. By controlling the number of revolutions of the feeding motor 44 according to the control means 60 for preventing excessive loosening of the wire (W) and the window (elongation) is provided.

Looking at the detailed structure of the control means 60, the front and rear of the right support frame 52, the two or more plural illustrated is illustrated that the three installed sensors) (61, 62, 63) a predetermined interval The array is installed.

At this time, the detection role of each detection sensor (61, 62, 63) will be clearly signed through the detailed description to be described later.

Referring to the operation state of the wire supply shock absorber configured as described above is as follows.

First, the feeding machine in which the cutting machine 10 operates to generate a pulling force on the wire W while the wire W is prevented from being entangled through the tangling prevention means, and at the same time constitutes the feeding means 40. As the 44 is operated, the wire W is supplied to the cutting machine 10 by appropriate amounts. At this time, when the feeding process of the wire W is driven by the feeding motor 44, the wire W drawn from the entanglement preventing means 30 is guided along the annular guide groove 43a of the wheel 43 for feeding. While passing between the guider 45 rotationally driven by the motor 44 and the auxiliary guider 47 installed adjacent thereto, it is guided to the shock absorbing means through the guide groove 48a of the fixed block 48. At this time, when the wire W passes between the guider 45 and the auxiliary guider 47, since the movable block 46 to which the auxiliary guider 47 is fixed is elastically installed by the spring S, the cutting machine The wire (W) is supplied while elastically flowing in response to the up and down transfer amount of the left and right guide weights (56, 57) constituting the buffer means (50) interlocked by the pulling force from the phosphorus (10) Lose.

Meanwhile, the force pulled from the cutting machine 10 and the supply amount of the wire W supplied by the feeding motor 44 must be balanced with each other. That is, the wire W is pulled so as to be inflated by the force pulled from the cutting machine 10 or is generated by increasing the amount of the wire W supplied by the feeding motor 44 as compared with the pull force. Excessive loosening of the wire W must be properly controlled.

Such a role is played by the buffer means, and when the wire W is pulled from the cutting machine 10, the left and right guide weights 56 and 57 are left and right support frames 51 and 52. It slides up and down along these guide grooves 51a and 52a. As a result, the pulling force from the cutting machine 10 does not work excessively. That is, the effect of the buffer is obtained. On the other hand, the effect of such a buffer and the loosening of the excessive wire (W) is to be controlled more stably through the control means 60, which will be described in detail the interlocking of the left, right guide weights 56, 57 As described above, the wire W is most stably supplied when interlocked around the middle sensor 62 of the sensors.

In this state, when the wire W supplied by the feeding motor 44 becomes larger than the pulling force from the cutting machine 10, the left and right guide weights 56 and 57 are positioned downward. At the same time, the detection sensor 63 detects the downward movement of the right guide weight 57 to stop the operation of the feeding motor 44. When the pulling force is applied from the cutting machine 10 in such a state, the left and right guide weights 56 and 57 are interlocked up and down again to give an appropriate cushioning effect to the wire W and at the same time feeding The motor 44 is also restarted to supply the appropriate amount of wire (W).

When the pulling force from the cutting machine 10 is relatively large as compared with the amount of the wire W supplied by the feeding motor 44, the wire W may be damaged. When the pulling force from the excessive cutting machine 10 is generated in this way, the left and right guide weights 56 and 57 linked thereto are transferred upwards, and at the same time, the transfer amount is detected by the detection sensor 61. do. When the detection sensor 61 detects the upper feed of the right guide weight 57 as described above, the rotation speed of the feeding motor 44 is further increased, thereby increasing the amount of wire W supplied by the feeding motor 44. Balance is achieved.

On the other hand, the present invention is to install only the left, right support frame (51, 52) to obtain a high impact of the buffer, but is not limited to this, if the force to pull from the cutting machine 10 is more buffered In order to increase the effect, providing a plurality of support frames and upper frames, and also providing a plurality of pulleys and guide weights will more reliably obtain the cushioning effect.

In addition, the present invention has been described with reference to the application to the device for supplying wire, but is not limited to this, it will be known to those skilled in the art that can be used also in supplying a thread or a rope.

As described above, according to the wire supply shock absorber according to the present invention, since the means for obtaining a buffer exists separately from the cutting machine, it is also applicable to other cutting machines. In other words, it is compatible. In addition, since the cushioning effect is obtained through the up and down flow of the guide weight, that is, the physical movement, it is possible to improve the workability without requiring repairs even for long time use, and in particular, it is possible to reduce the production cost. have.
