L Prior Art 3 The description of the prior art is shown in Fig. 7. In the conventional stamping line, a coil is passed through a leveler 3 for connecting the material to the buffer section, and is unrolled by the _unroller 2 Feeding H) to-the intermittent feeding device 7 to feed the coil material i to a mechanical punch 6, and the buffer section is called-a looper for generating a ring 5. The leveler 3 is a device for straightening the bending in the coil and pressing the lower rollers against each other in a staggered configuration. Usually, the upper roller is pressed down against the lower roller. The material can therefore be continuously stretched and compressed to flatten the web. The 15 leveler 3 is generally composed of a pressure roller and a correction roller, the pressure roller is used to pull in the material, and the correction roller is used to flatten the material. Throughout the section, if the coil is fed to the feeding device and reaches the mechanical punch, the feeding action is also performed according to the pressing operation of repeated movement and stop. The vibration generated at the start and stop will be applied to the Roll 20 material, so the roll material will vibrate and will produce an open phenomenon called beating. When the field is beating, not only will an excessive load be applied to the feed, but also in the -Bends or -scratches also occur in the web. Therefore, a buffer section called a looper must be provided. A conventional method for reducing the beating in the coil is a coil feeding device 1229652. The coil feeding device includes a looper, and a U-shaped punch with a U-shaped buffer section. 4aTT ^ i " 8-shaped looper for punching section. > Once it is furious, the two are “buffered”. 5 The operating speed cannot be increased. ::: Fully utilizes the function of stamping.

In addition, since a long buffer section must be set, the line length of the pressure line will increase. τ In order to solve the aforementioned problems, there has been a coil feeding device that has less bounce even under a high-speed fall. The coil mining device can reduce the load of the intermittent feed farm and reduce the reed line. It is 15 degrees long. See, for example, U.S. Patent No. 5,392,977.乂 As shown in FIG. 8, this device is configured so that a pair of feed rollers provided with a servo motor are arranged as a bow controller 4 near the intermittent feeding device 7 of the mechanical punch 6, and When a proper curve $ is formed in j, the feeding rollers feed the material to the intermittent feeding device 7. In addition, a size 5 for detecting the bend 5 in the coil 1 is also provided. The coil 丨 is fed to the intermittent feeding device 7, and the proper bending shape of the bend 5 is maintained by controlling the rotation of the servo motor according to the feeding amount of the coil 1 fed by the feed roller. Therefore, since a high-speed operation can be achieved and the jitter in FIG. 7 is minimized to increase the σ feed amount by reducing the 间歇 229652 load applied to the intermittent feeding device 7, and to keep the pressure line. ’夂〗 Therefore, the punch can be shortened. However, the 5 10 15 material feeding device 2 = the variety of types of materials in the past year, so this volume ^ ^ ~ corresponds to various materials and feeding conditions. At the most ^ material curvature, the limit of the radius of curvature of the material is usually the limit, ~ Medium =: Γ and it is known that as long as the thick material is not exceeded, the clever song ^ / fold ° is expressed in-thin material and in In the thick material: the grain thickness is different, and, of course, the middle ten must be formed-large bend. According to the foregoing, the above-mentioned journal coil feeding device is placed in the coil feeding device, which feeds from the lower side up to the inverse person ^ 7 and is connected with the coil 1 — big waiting 1 ^ = = there is a song off, if this is formed Da Zi Qu 5, in order to form even below. However, the controller 4 is set to form a bend on the lower side of the coil ^ of the intermittent feeding device 7, and in the other two, it must be from the unwinder 2 feet. Therefore, a large radius of the decorator + taxi can not form 1 when the bend to a fairly large limit 'and may control the coffee to be placed close to the room: Feed two: the part is the bend of the _, can have —Small feed two = place 'Because 7 must be compared with the intermittent feed device for each bismuth kernel, as shown in Figure 9' So the bend of the material 5 'needs to have-most of the time. Therefore, if material Compared with thin materials, 20 1229652 the stamping line will be very long. In addition, suppose the aforementioned conventional system has—the coil becomes free when the coil flows from the unwinder 2 to the intermittent feeding device 7. Section, a slight jump of the coil in that section will destroy the quality of the coil. In the device shown in Figure 8 of the previous article, since the coil is controlled by the f-curve controller 4 The upstream part hangs down, the coil i whose f-fold is corrected by the leveler 3 is left for a long period of time before starting the feeding operation, so the bend will be generated again, and when the coil starts or stops feeding Will produce-slight beating, so scratches will occur. [Summary of the invention] The summary of the invention is complicated In the foregoing problem, the present invention provides a coil material feeding device capable of feeding material in a winding manner and with high quality. In other words, the present invention provides a coil material feeding device having a -leveler (-material correction function) in which The angle can be adjusted at 15. In order to achieve the foregoing object, the present invention provides a coil feeding device for feeding the coil to an intermittent feeding device of a mechanical punch, including:-a coil feeding portion;- Position sensor 'is set on the downstream side of the coil feed part and 20 can detect the amount of bending of a coil;-the control device' made to control according to the signal output by the position sensor-servo motor 'to The feeding amount of the coil is controlled by a feeding roller; and-a bracket 'is used to maintain the coil feeding portion in the coil feeding portion 1229652 to change a state in which one of the material parts can be adjusted according to conditions The feeding angle of the coil.-The coil feeding part is the material arranged in the intermittent feeding device. 5 10 15 卞 门 休 = side-by-side-the feeding roller is used to feed the material to the intermittent feeding device. Formed in this material—appropriately bend the horse to drive the feeding rollers; —the material correction part is constituted as = with most of them are arranged above and below the line and forward and upward, on the parent The drum line of the drum at the wrongly moved position can feed the material to the intermittent feeding device to pass through the gap between the upper financial line and break the _ or downstream side of the feed roller; And a Nandu adjusting mechanism for adjusting the distance between the upper and lower roller lines in the material correction part according to the quality and thickness of the material to be fed. The gap distance between the upper and lower roller lines is used to adjust the degree of bending elimination in the coil. In the coil feeding device of the present invention, the coil feeding portion including the feeding roller driven by the servo motor is arranged close to At the intermittent feeding device of the mechanical punch, and when the coil is fed by the feeding rollers, the proper bend is formed and the material is fed. In addition, since the coil is based on a signal output by a position sensor that detects the size of the bend in the coil, the rotation of the servo motor is controlled to control the feeding amount of the coil fed by the feeding rollers, and This feeds to the intermittent feeding device | still maintains the proper curved shape, so high-speed operation can be accomplished with less runout and a smaller load applied to the intermittent feeding device. In addition, the feed rollers have such lines, most of which are arranged in a straight line on the line with a correction function and a material correction function, which straightens the material: In addition to the lower roller line, it is achieved by 1st and 2nd meandering and eliminating the internal stress of the material. The 5 10 15 feed direction: each roller of = Γ is placed at a position where it passes through the material before the coil, so that the coil in the coil is vertically f-folded during the outer shape II. With the intermittent feeding device along each roll, the roll = material feeding portion is arranged close to the installation angle of the coil material replacement portion is set to the roll in the break feeding device: of which, the angle to feed is The #, ,, / feed direction of the coil in the room comes from the ^ direction of the coil feed portion. From the vertical direction to the same function as the forward direction: the material feeding part has a good quality state of the coil feeding according to the present invention at the angle, where the bend 3 'the material to be fed is in the- And can fully correspond to-the need for high accuracy. In addition =: It is recommended to form, because the installation angle of the coil feed part is adjustable :: It can form a fine and gentle bend instead of the conventional four, so 'the installation angle must be changed according to the thickness of the material to bend the radius R However, even for thick materials, the test curve radius R can be easily increased by setting the installation angle close to the forward direction of the 矣 h lane material in the intermittent feeding device. At this time, since the distortion is changed only by adjusting the angle and it is not necessary to move the position of the feeding device like a conventional device, it is not necessary to lengthen the punch line. 20 1229652 In addition, since the coil feeding device of the present invention is added with a leveling function, the independently provided leveling device is not needed in the past, and the punching line from the leveler to the feeding device can be shortened. At the same time, it is possible to avoid scratches and folds due to runout between the leveler and the feeding device. In addition, the roller lines can be composed of the aforementioned feed rollers and used as a pair to force out the material above and below the large diameter roller by a high torque, and most of them repeat a small bend and stretch to correct the material Small diameter roller wire. 10 Moreover, the large-diameter feed rollers and the small-diameter roller lines may be independently provided with respective distance adjustment mechanisms between the rollers, and the adjustment method may be a mechanical type or a pneumatic type. Furthermore, the rotation driving force of the large-diameter roller can be transmitted to the small-diameter roller lines, thereby enabling the small-diameter roller lines to rotate. 15 Therefore, the feed force generated by the feed rollers can transfer the material without being weakened by the small diameter drum lines.

The Japanese, σ: 28 series, is arranged on-working on the side of the mechanical punch 27. H feeds the county material U horizontally between the-lower die M and-. The mechanical punch 27 has a motor in a similar way to a user—a flywheel that stores its rotational force, a crankshaft that converts the rotational force into a straight 10 15 line reciprocating action, and a _ The rotation angle detection device 31 and the like of the rotation angle of the crank shaft.口 口 、 — 下 将 〇 儿 明月; J describes the operation of the example. As shown in FIG. 1, the unwinding circle is rolled out in the direction of 4 reels, so that the roll u is unwound from the lower side. In this roll, the feeding device 13 is adjusted by the height adjustment device 2G to adjust the area of the support and the angle adjustment device 21 is used to adjust the angle of the female feed 15 wound 22 and the female rose 22 to be arranged away from the interval. The position of the feeding device 28 enables the pre-defined bending state between the coil feeding device 13 and the intermittent feeding device M, and the coil feeding portion 22 is positioned at the bottom = and at the intermittent feeding position 28 upstream side. In addition, the lower position sensor 23 is arranged at a position for detecting the minimum bending length L1 of the coil 11 ', and the upper 4 position sensing || The position of L2. The position sensors 23 and 24 are rotatably mounted on the bracket 25 via various levers, as shown in FIG. 6, and the positions can be adjusted by turning the levers. The position sensors 23 and 24 in this embodiment use a proximity switch, but other kinds of position sensors can be used. In order to maintain the bending state of the coil 11 between the intermittent feeding device 28 and the coil feeding device 13, there is a difference between the minimum bending length L1 and the maximum bending length L2, and a difference between the lengths L1 and L2 A condition equal to or greater than the feed pitch of the 5 mechanical punch 27, the bending state is monitored by the position sensors 23 and 24. When the bending of the coil is reduced and the minimum bending length L1 is detected by the position sensor 23, the signal is transmitted to the control device 26, and the control device 26 controls the servo through the driver 17. The motor 16 drives the rotation angle of the feed roller 14 on the drive side by an angle of 10 plus a rotation angle α to increase the feed amount of the roll material 11 and sets an appropriate bending length L3. Conversely, when the bending becomes large and the maximum bending length L2 is measured by the position sensor 24, the signal is transmitted to the control device 26, and the control device 26 controls the servo motor 16 via the driver 17 By driving, the rotation angle of the feeding drum 14 is reduced by a rotation angle α 15 to reduce the feeding amount of the roll material 11, and the proper bending length L3 is set. The minimum bending length L1, the maximum bending length L2, and the appropriate bending length L3 are determined by the shape and physical properties of the coil 11 to be used, the distance between the coil feeding device 13 and the intermittent feeding device 28, and the like. Decide. As described above, according to the foregoing embodiment, since the minimum and maximum bending 20 lengths L1 and L2 are monitored by the position sensors 23 and 24, and the coil 11 is controlled by the control device 26 The feeding amount of the feeding rollers 14 and 15 is fed to the intermittent feeding device 28, so high-speed operation with less pulsation and a smaller load of the intermittent feeding device 28 can be performed. In this example, operations and actions to monitor the minimum and maximum bending lengths and control the feeding amount of the 15 1229652 feed roller to the most appropriate value in the aforementioned patent can be incorporated into the present invention as a reference. In this embodiment, as shown in Fig. 2, the driving motor 16 rotates the large-diameter roller 14 to feed the web. A spur gear 44 is provided in the large-diameter 5 roller 14. In addition, a gear mechanism is configured so that a transmission gear 45 combined with the spur gear 44 is connected to a small ui wheel provided in the small-diameter roller 18. 46 is engaged, and then rotation in the same direction as the rotation is transmitted via a transmission gear 47. Therefore, the feeding force exerted by the feeding roller 14 on the coil material is not reduced by the leveler portion (the small-diameter roller line) 19, and 10 the material is bent in the same way that the leveler portion is not provided. It is formed under the same conditions and can be fed to this intermittent feeding device 28. In addition, since the distance adjusting function elements 41, 42 and 43 are separately provided between the rollers 14 and 15 and between the rollers 18, the volume can be adjusted according to the functions of the rollers. Material holding, correction and 15 feed adjustment to various appropriate conditions. Since the installation angle of the coil feeding portion is set relative to the forward direction of the coil in the intermittent feeding device, from the vertical direction to the direction from the feeding portion to the same direction as the a Within the range of the feeding direction of the coil, a mechanism capable of adjusting the curved shape between the semicircular solitary and the quarter-round fox can be achieved, and the curved shape with an appropriate δ radius can be easily formed according to the coil. And the web can be fed at a higher speed. In addition, 'because the coil feeding device also has the function of correcting the coil b, it does not require an independent leveler and can directly feed coils with high quality and no coil bending. To this intermittent feeding device 'the line length of the entire stamping line can therefore be shortened. In addition, the curved shape can be monitored by using two position sensors arranged above and below the rotation control device of the driving drum of the curved disk, and the initial set optimal curved shape can be maintained. In this example, in order to feed the coil from the unwinder to the intermittent feeding device at a high speed, a large torque is required in the feeding rollers. If the feed drive (the coil feed) is obtained using only small diameter rollers such as Yanhai, a large-sized drive motor is required to rotate at high speed under the condition that friction is applied to these small diameter 10 rollers Such small diameter rollers. However, according to the second structure, since all the feeding rollers for forming the bending and feeding the coil are independently provided, the feeding function as the coil feeding device is high. 5 Also, since the feed roller also serves as a coil guide pitch roller for correcting the coil, the device can be closely arranged. 15 In addition, 'if the coil passes through the flattener portion of the small diameter roller lines, the small roller lines must rotate. However, since the driving source can be shared by transmitting the driving force of the large straight #feed roller through the gears, it can save more space.
