The description of the prior art is shown in FIG. 7. In a conventional stamping line, a coil of material is fed by a decoiling device 2 through a leveler 3 for connecting the material and a buffer section. -Intermittent feeding device 7 to feed the web! It is fed 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 staggered arrangement above and the lower roller against each other. Usually, the upper roller is pressed downward 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. Generally, if the coil is fed to the feeding device to reach the mechanical punch, the feeding operation is performed intermittently 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, so the roll will vibrate and produce a wrinkle phenomenon called pulsation. When the aforementioned pulsation occurs, not only will an excessive load be applied. On the feeding device, a bend or a scratch will also be generated in the coil. Therefore, a buffer section called a looper must be provided. A known method to reduce the beating in the remote coil is a coil feed unit 5 200418706, which feeds the dream department ― I clothes include-U-shaped hit with -U-shaped buffer section ... and u S-shaped looper of the buffer section. However, the "U-shaped hiccups and clear loops", although the beat is 4 compared with the unset object ^, but the beat will still occur due to high-speed operation. Therefore, the operating speed cannot be increased, and although high-speed stamping is required recently, But it ca n’t — fully utilize the function of punching. In addition, because the looper itself has no driving source, the coil relies on the pulling force of the intermittent feeding device, and — the leveling of the coil unwound by the apparatus The pressing force of the device is used to feed, so; ίο ^, = so many 'thus reduces the feed amount of the closing feed device and the leveling 2. In addition, because a long buffer section must be provided, the line of stamping and table It will increase. In order to understand these problems described above, there is a coil feeding device that has fewer cranes even at high speed operation. The coil feeding device can reduce the load of the intermittent feeding device and shorten it. The length of the stamping line ^ For example, please refer to US Patent No. 5,392,977. As shown in FIG. 8, this device is configured so that a pair of servo horses can be provided; the feeding roller is arranged close to the interval of the mechanical punch 6 Feed pack, When the bow controller 4 is formed, and a proper bend 5 is formed in the roll 1, the 20〇 temple feed roller feeds the material to the intermittent feed device 7. In addition, it is also useful to detect the roll in the roll. The size of the bending 5 of the material 1. The coil 丨 is fed to the intermittent feeding device 7 and the rotation of the servo motor is controlled by the feeding amount of the coil 1 according to a lion and the like to control the rotation of the servo motor while the bending is maintained. 5, the shape of Tian Xunqu. Therefore, because a high-speed operation can be achieved and the 7th figure is reduced to Yuan Shao to reduce the load applied to the intermittent feeding device 7 to reduce the pressure on the line. In addition, the amount of bending can be reduced, so the punch can be shortened. However, due to the variety of stamping materials in recent years, the volume " should correspond to various materials and feeding conditions. When riding at most 20% of the bending The limit of the radius of curvature of the material is usually the limit, which is 叱 500 times the thickness of Xi Er, and it is known that as long as it does not exceed the -thick material Γ, no bending will occur. This means that the -thin material and the Thick material: the allowable size of two bends is not 'And, of course, ^ tributes form a large Zeng, Qu. ^ According to the aforementioned matter, the coil feeding device described in the aforementioned publications guard = split system is placed under the intermittent feeding device 7 and with the coil; -Most of the things related to the knowledge, if the big bend 5 is formed, in order to form it ^ 'must_the bend control relay 4 is set to the second volume of the intermittent feeding device 7 is' on the downstream side of the feeding device, from The unwinder 2 R is therefore formed side-bend 'and here a large radius R is required. Therefore, the device is subject to considerable restrictions in the vertical direction, and it may be possible to form a proper bend. '—About a quarter of a round—Curving 5 series' from the bending control to the intermittent feeding device 7. ㈣ For the four parts, the bending controller 4 can be arranged near the intermittent feeding position ^ because of the 溥The bend 5 of the material can have a small radius R, but the intermittent feed = 7 must be compared with the thin material of the shell, clothing, and flame, ^ and extended away from the intermittent feed device 7 to fit ... The thick material 5 needs a large abundance, as shown in Figure 9. Therefore, if there is a large +, it will be very long compared to thin materials. In addition, it is assumed that the aforementioned conventional system has a section where the coil becomes free when the coil 1 flows from the unwinder 2 toward the intermittent feeding device 7, and a slight jump of the coil in the section will be destroyed The quality of the coil. In the device shown in FIG. 8 in the aforementioned publication 5, since the coil is suspended from the upstream portion of the bending controller 4, the coil 1 whose bend is corrected by the leveler 3 is at the beginning of feeding. Allow it to stand for a long time before operation, so the bend will occur again, and the coil will have a slight jump when starting or stopping the feeding, so it will cause scratches. [Summary of the Invention] Summary of the Invention In view of the foregoing problems, the present invention provides a coil feeding device capable of feeding a material flexibly and with high quality. In other words, the present invention provides a coil feeding device having a leveler (a material correction function) in which the installation angle is adjustable.

In addition, the feeding rollers of the temple have such lines. Most of the rollers are arranged in straight lines on the upper and lower sides. They also have a material correction function that can pass the material through the upper and lower sides. This is achieved by straightening the bends in the material between the roller lines and eliminating the internal stress of the material. In addition, each of the rollers in the upper and lower roller lines is arranged at a position of staggered movement in the forward direction with respect to the coil, thereby bending the coil in the coil between the upper and lower rollers. The web is vertically bent and stretched during the outer shape of each roll. The coil feeding portion is arranged near the intermittent feeding device, and the installation angle of the coil feeding portion is set so that the coil is fed at an angle within a range, with respect to the interval 10 The feed direction of the coil in the break feeding device, a feed direction of the coil from the feed portion of the coil is from a vertical direction to the same direction as the advance direction. Therefore, the coil feed portion has a function capable of adjusting the angle. According to the coil material feeding device of the present invention, the material to be sent to the hall is in a better quality state, wherein the bending is corrected before the material is intended to be fed, and it can fully correspond to a stamping requiring high accuracy. In addition, with respect to the bending formation, since the mounting angle of the coil feed portion is adjustable, a slightly gentle bending can be formed instead of the conventional quarter arc. Therefore, the installation angle must be changed according to the thickness of the material to adjust the bend radius R. However, even for thick materials, the installation angle can be set close to the forward direction of the coil in the intermittent feeding device. The bending radius R is easily increased. At this time, since the bending radius can be 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 punching line. 10 In addition, since the coil feeding device of the present invention is added with a leveling function, the independent setting of the leveling device is not required 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 breaks caused by the level of the leveling 1 and the material device. In addition, these roller lines can be constituted by the aforementioned feed rollers and used as a pair to strongly squeeze out the material above and below the large diameter roll by high torque, and most of the repeats-small bends and stretches to correct the Material of small diameter roller line. ^ Wenwen and other large-diameter feed rollers and these small-diameter roller lines can be provided with their own distance-adjusting mechanism in the standing position of the rollers, and the adjustment method can be a mechanical or a pneumatic type. -Furthermore, the rotation driving force of the large-diameter roller can be transmitted to the small straight roller lines, whereby the small-diameter roller lines can be rotated. Therefore, the feeding force generated by the feeding rollers can transfer the material without being weakened by the small-diameter roller lines. Schematic description # # 、 图.

[Embodiment 3 10 Description of the preferred embodiment FIG. 1 is a schematic diagram of the outline structure of an example of a stamping line according to the present invention. Reference numeral 11 represents a coil, and the coil 11 is released by an unwinder 12. Out. Reference numeral 13 denotes an embodiment of a coil feeding device according to the present invention. The coil feeding device 13 has a coil feeding portion 22, and position sensors 23 and 24 for detecting a bending amount of the coil 15 material 11 Moreover, these components are mounted on a bracket 25 so that the height thereof can be adjusted by a height adjusting device 20. After the coil 11 passes through the coil feeding device 13 and forms a bend, the remote coil 11 is fed to a mechanical punch 27 via an intermittent feeding device 28 to receive a punching process. 20 In the coil feeding device Π, the coil feeding portion 22 includes a pair of feeding rollers 14 and 15 for conveying the coil 11;-for driving the rollers 14 and 15 in the feeding rollers 14 and 15; Servo motor 16 for the rotation of the drum 14; a drive 17 for driving the servo motor 16;-material correction section 19, most of which are arranged in a line approximately 12 of the upper and lower drum lines 12 above 14 On each side of the side and in the forward direction, it is placed upstream or downstream of the temple feed roller 18 in a staggered position; and-an angle adjustment device 21 that can adjust the feeding direction of the coil U. In the tree material correction section ^, the upper and lower roller lines are configured so that the material fed to the gate-feeding device can pass through the gap between the upper and lower roller lines. When the coil has been said between the upper and lower roller lines, the volume # 11 is zigzag vertically and stretches along each roller-like shape and straightens the bow. The upper and lower roller lines 10 of the material correcting part 19 are adjusted to a door gap by a height adjustment mechanism consisting of two adjusting screws two 43 to form a complete gap distance according to the quality and thickness of the material to be fed. The distance & shown in Figure 2 can be used to adjust the degree of bending and straightening of the coil. 4 The angle adjustment device η of the coil feeding portion 22 will set the installation angle of the coil feeding portion 22 corresponding to conditions such as the thickness of the coil within a range, where the coil n is determined by the coil The release direction of the feeding portion 22 is relative to the forward direction of the coil in the intermittent feeding device 28 (approximately in the horizontal direction), from -vertical to-the same horizontal direction as the forward direction of the coil (See Figure 3). In other words, when the release direction of the coil from the coil feed portion is set to 20%-a state close to the vertical direction to the forward direction of the intermittent feeding device '-the curved shape is formed as shown in Fig. 4 Quarter arc. In addition, when the coil is released in a horizontal direction close to that shown in Fig. 5, the bend becomes approximately -semicircle and the coil is fed in a -semicircular arc shape. In the present invention, the 5 Ohm I angle is set within a range including these directions. 13 24 series == The driver 17 of 13 is connected to the position sensors 23 and 2 1 26, and the control device 26 is also used as a bed 27 and the intermittent feeding device 28. It is arranged on a working day on the side of the mechanical punch 27, and the coil 11 can be horizontally positioned. Thousands also feed in the—lower core and—upper mold 30. The money punch 27 has a motor in a similar way to a user, a flywheel to store its rotational force, and _ to convert the rotational force into a straight line. The reciprocating crankshaft—a square-rotation angle detection device 31 that measures the rotation angle of the crankshaft by using the same method. The operation of the foregoing embodiment will be described below. As shown in Fig. I, the unwinder 2 defines the direction of the reel, so that the roll u is unwound from the lower side. The coil feeding device divides the height of the bracket 25 through the height adjusting device, and arranges the coil feeding portion 22 by using the angle adjusting device to arrange it away from the closing feeding device μ Position so that a pre-determined bending state can be obtained between the coil feeding device U and the intermittent feeding device M, and the coil feeding portion 22 is positioned below and on the upstream side of the mule device 28 . In addition, the lower position sensor 23 is configured to detect a minimum bending length of the coil, and the upper position sensor 24 is configured to measure the coil with ^ Position of the bending length L2. The position sensors are rotatably mounted on the bracket 25 via various levers, as shown in Fig. 6, and the position can be adjusted by turning the levers. The position sensors 23 and 24 in this embodiment use a proximity switch ', but other types of position sensors may 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 mechanical punch 27, the bending state is monitored by the position sensors 23 and 24. When the bending of the coil 11 becomes smaller 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 via the driver 17 The driving of the motor 16 makes the rotation angle of the feed roller 14 on the drive side plus an angle of rotation α to increase the feed amount of the coil material 11 and sets an appropriate bending length L3. Conversely, when the bending becomes large and the maximum bending length L2 is detected 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 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 of material, 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 mentioned 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 200418706 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. _Spur gear 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 coupled with a small gear 46 provided in the small-diameter roller ι8. The coupling, and then the rotation in the same rotation direction 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 the intermittent feeding strike 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 hold, correction and 15 feed adjustment to various appropriate conditions. Since the security angle of the feeding portion of the coil 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 feeding direction. Within the range of the feeding direction of the coil, a mechanism capable of adjusting the curved shape between a semicircular arc and a quarter arc can be achieved, and a curved shape with an appropriate 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, it does not need the separate leveler and can directly feed coils with high quality and no coils. Intermittent feeding device, so the line length of the entire stamping line can be shortened. In addition, the curved shape can always be monitored by two position sensors arranged above and below the rotation control device of the curved and the driving drum, 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 these small diameter rollers, a large-sized drive motor is required to rotate the rollers at high speed while friction is applied to the small diameter 10 rollers. Small diameter roller. However, according to this 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. In addition, 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 the leveler portion of the small-diameter roller lines, the small roller lines must be rotated. However, since the driving source can be shared by transmitting the driving force of the large-diameter feed roller through the gears, it can save more space.
