[Industrial applications]

 The present invention relates to a belt-shaped body guiding device for feeding a belt-shaped body from a coil mounted on a drum of an uncoiler and guiding it to a processing device such as a leveler feeder or a pressing device.

[0002]

[Prior Art]

 FIG. 7 is a front view of a typical conventional coil supply device 1. A coil 3 is formed by winding a strip 2 such as a steel strip, and cutting or pressing is performed while pulling out the strip 2 from the coil 3 as needed. To use the coil 3 in this way, the coil 3 is mounted on the drum 5 of the uncoiler 4. Next, after angularly displacing the arm 8 of the coil pressing mechanism 7 having the roller 6 attached to the tip thereof to press the coil 3 with the roller 6, the coil 3 is prevented from being separated when the coil 3 is transferred. The binding band wound around the outer portion of the coil 3 is cut.

After that, the guide member 9 formed to be curved substantially along the outer peripheral surface of the coil 3 is angularly displaced in the arrow A1 direction by the action of the cylinder 10 connected to the base end of the guide member 9. 5 is rotated in the direction of arrow A2. As a result, the strip 2 is unwound from the coil 3, guided by the guide member 9, and guided into the leveler feeder 11 arranged at the subsequent stage of the uncoiler 4. The leveler feeder 11 is provided with a pressing roller 12 that presses the belt-shaped body 2 from above at the introduction portion of the belt-shaped body 2, and the pressing roller 12 is displaced toward and away from the belt-shaped body 2 by an arm 13.

Here, the pressing roller 12 is in the position shown in FIG. 7 until the belt-shaped body 2 passes below the pressing roller 12, and when the belt-shaped body 2 passes below the pressing roller 12, arrow A3 The belt 2 is angularly displaced in the direction to press the belt 2 from above, so that the belt 2 smoothly enters the leveler feeder 11.

[Problems to be solved by the device]

 However, depending on the material or the thickness of the strip-shaped body 2 that constitutes the coil 3, the strength of the so-called stiffness, or the strength of the winding habit, when it is introduced into the leveler feeder 11, varies. Is.

That is, when the band-shaped body 2 is made of a relatively stiff material or has a large plate thickness, the band-shaped body 2 has a relatively strong stiffness and a strong curl.

For this reason, as shown in FIG. 8 (1), the strip-shaped body 2 unwound from the coil 3 is supported by the guide member 9 and then has a winding portion 2a that is wound upward. It approaches the coil 3 again or moves in an undesired direction without going to the leveler feeder 11. Further, when the band-shaped body 2 is made of a relatively soft material or has a small plate thickness, the stiffness is weak, and when the band-shaped body 2 is unwound, the curl is resolved relatively quickly. In such a case, as shown in FIG. 8 (2), the band-shaped body 2 that has passed through the guide member 9 is not supported from below by the guide member 9, so that a hanging portion 2b that hangs downward is generated. ..

In any of the above cases, the strip 2 cannot be introduced into the leveler feeder 11, and it is necessary to manually introduce the tip end of the strip 2 into the leveler feeder 11. Such work is time-consuming and dangerous, and the work of supplying the belt-shaped body 2 to the leveler feeder 11 cannot be automated, and the work efficiency when performing various processing work using the coil 3 is reduced. Have challenges.

The object of the present invention is to solve the above-mentioned technical problems, to automate the work for guiding the strip from the uncoiler to the processing device, and to perform the work in a simple manner to significantly improve the work efficiency. It is an object of the present invention to provide a belt-shaped guide device which has a simple structure and is inexpensive to manufacture.

[0010]

Means for Solving the Problems The present invention provides a guide device for guiding a strip-shaped body fed out from a coil to the next process, in which the strip-shaped body is fed from a coil attached to an uncoiler drum rather than a feeding position. A support member that is arranged on the downstream side of the body in the conveying direction and on the lower side of the drum, is angularly displaced around the upstream end of the conveying direction, and approaches / separates from the drum to support the belt-shaped body from below. And a guide member provided near the free end side tip of the support member, with a peeling member pivotally supported so as to be angularly displaceable around a pivot parallel to the drum of the uncoiler, and a magnetic roller rotatably fitted to the pivot. The guide member is formed in such a manner that the guide member is formed so that an end portion of the stripping member on the downstream side in the transport direction of the strip member is projected upward from the magnetic roller by being angularly displaced. body A guiding device.

[0011]

[Action]

 According to the present invention, the strip is supported by the support member, and the support member is angularly displaced around the upstream end of the strip in the transport direction, so that the strip is disposed at the free end of the support member. The band-shaped body is attracted by the magnetic roller thus formed, and its tip is guided to a desired position. When the strip-shaped body is introduced at the position, the stripping member coaxial with the magnetic roller is angularly displaced, the downstream end of the stripping member in the transport direction is projected above the magnetic roller, and the strip-shaped body is pushed up to form the strip-shaped body. By moving the body away from the magnetic roller, the subsequent feeding of the band-shaped body is facilitated.

【Example】

 FIG. 1 is a front view of a strip feeding device 22 including a strip guiding device 21 according to an embodiment of the present invention. The supply device 22 of the present embodiment is configured to feed a strip-shaped body 26 from a coil 25 made of a steel plate or the like mounted on a drum 24 of an uncoiler 23 and supply the strip-shaped body 26 to a leveler feeder 27, for example. The strip 26 that has passed through the leveler feeder 27 is supplied to another processing device such as a pressing device. The coil 25 mounted on the drum 24 has its outer peripheral surface pressed radially inward by the roller 29 of the coil pressing mechanism 28, and cuts the binding band that binds the outer peripheral surface of the coil 25 during transportation or the like. At this time, the coil 25 is unwound and held so as not to come loose.

A roller 29 that abuts the coil 25 is rotatably provided at one end of the coil pressing mechanism 28, and a rod 31 of a cylinder 30 is connected to the other end of the roller 29. The L-shaped arm 33 is provided. A driving force is transmitted from the motor 34 mounted on the arm 33 to the roller 29 by a belt or a roller chain 35, and the roller 29 is rotationally driven in the arrow A1 direction. The arm 33 is displaced by the expansion / contraction operation of the rod 31 so that the roller 29 moves toward / away from the coil 25 in the arrow A2 direction or the arrow A3 direction.

Further, the coil 25 is rotationally driven in the direction of arrow A4 by the rotation of the roller 29 in the direction of arrow A1, and the strip 26 is gradually fed out from the feeding position 36. At this time, the uncoiler 23 has a configuration such as a motor for generating a rotational torque in the drum 24 in the direction opposite to the arrow A4 direction. That is, the roller 29 presses the surface of the coil 25 in a state where the drum 24 excessively rotates due to the rotation thereof and the coil 25 is not unwound excessively.

The strip-shaped body 26 gradually delivered from the delivery position 36 is supported from below by the guide device 21 and guided to the leveler feeder 27 as described later.

In the leveler feeder 27, on the upstream side of the belt-shaped body 26 in the conveying direction B1, the belt-shaped body 26 extends obliquely upward while curving downwardly as it comes close to the leveler feeder 27. A guide plate 40 is arranged near the inlet 39. At the position where the strip 26 guided by the guide plate 40 reaches at the introduction port 39, the tip of the strip 26 guided is prevented from moving further upward, and the tip is directed toward the inside of the leveler feeder 27. A guide plate 41 for guiding is provided. Between the guide plates 40 and 41, an arm 42 whose middle portion bends toward the upstream side in the transport direction B1 is provided so as to be angularly displaceable around a pivot 43 as a fulcrum. A rod 45 of a cylinder 44 is angularly displaceably coupled to the arm 42 closer to the end than the pivot 43, and a roller 46 is rotatably provided at the end of the arm 42 opposite to the rod 45. By the expansion / contraction operation in the arrow B2 direction or the arrow B3 direction, an angular displacement operation is performed in which the strip 26 is pressed toward the inner side of the leveler feeder 27 or is separated outward.

The leveler feeder 27 is provided with a conveyance roller 47 at a position where the belt-shaped body 26 is pinched between the leveler feeder 27 and the roller 46 when the roller 46 is angularly displaced inward. The strip 26 from 40 is guided to the vicinity of the conveying roller 47 via a supporting roller 48. With respect to the conveying rollers 47, a plurality of leveling rollers 49 arranged in a zigzag pattern that press the strips 26 from both sides in the plate thickness direction on the downstream side in the conveying direction B1, and a leveler feeder 27 by sandwiching the strips 26. As an example arranged in the latter stage, a pair of transport rollers 50 for transporting the belt-shaped body 26 with a predetermined length and a predetermined timing are provided in various processing devices such as a press device.

That is, until the tip of the strip 26 passes through the leveler feeder 27 and is clamped by the conveyor roller 50, the arm 42 is angularly displaced in the direction of arrow B4. The belt-shaped body 26 is pinched and conveyed between the roller 46 and the conveyance roller 47. After the tip of the belt-shaped body 26 is pinched by the pair of conveyance rollers 50, the rod 45 retracts in the direction of arrow B3. , The roller 46 is angularly displaced in the direction of arrow B5 and separates from the belt-like body 26.

2 is a partially enlarged front view of FIG. 1, FIG. 3 is a sectional view taken along the section line X3-X3 of FIG. 2, and FIG. 4 is a partially enlarged sectional view of FIG.

The guide device 21 is arranged below the drum 24 of the uncoiler 23 on the downstream side of the feeding position 36 of the strip 26 from the uncoiler 23 in the conveying direction of the strip, and moves the strip 26 from below. It has a support member 37 that supports and guides, and a guide member 38 that is disposed near the front end of the support member 37 so as to be angularly displaceable.

The support member 37 is arranged downstream of the position where the strip 26 is fed out in the transport direction of the strip and below the drum 24. Further, the support member 37 is angularly displaced with respect to the machine body of the uncoiler 23 about the pivot 51 provided at the upstream end in the transport direction as a fulcrum, and moves toward and away from the drum 24 along the transport direction B1. A pair of tapered side plates 82 made of a bent iron or other metal material, support seats 52 fixed between the side plates 82, and a coating made of vinyl chloride resin or the like fixed on the upper surface of the support seats 52. And layer 53. The synthetic resin material of the coating layer 53 may be of any other type as long as it has wear resistance, relatively low hardness and non-magnetic property, and serves to alleviate contact friction with the belt-shaped body 26. As the angular displacement means of the support member 37, as shown in the figure, a piston rod 81 pivotally supported by the tip of an arm 54 integrally formed with a side plate 82 and a cylinder 80 for driving this piston rod 81 are used. To be done.

A guide member attachment window 55 is formed at the free end side tip portion of the support member 37, and a guide member 38 is attached to the guide member attachment window 55. The guide member 38 is disposed and supported by the support member 37, and has a pivot 65 parallel to the drum 24 of the uncoiler 23, a peeling plate 66 pivotally supported by the pivot 65 and angularly displaced about the pivot 65, The magnetic roller 67 is rotatably supported by the shaft 65.

As shown in the cross-sectional views of FIGS. 3 and 4 and the perspective view of FIG. 5, the peeling plate 66 is made of an iron substrate 68, and is disposed on one surface of the substrate 68 with a space therebetween. A plurality of support plates 70 made of stainless steel whose ends are fixed by screws 69 are assembled and formed, and the support plate 70 is provided with a shaft hole 71 into which the pivot shaft 65 is inserted. The peeling plate 66 has a piston rod 58 of a cylinder 57 pivotally attached to the tip of a projecting piece 72 projectingly provided on the other surface of the base plate 68, and is angularly displaceable around the pivot shaft 65.

Oil-free sintered bushes 73, 74 are mounted on the sliding contact surface between the pivot shaft 65 and the peeling plate 66 and the sliding contact surface between the pivot shaft 65 and the magnetic roller 67.

Fixing bolts 56 are screwed into the pivot shaft 65 from both sides of the support member 37 to be fixed.

The magnetic roller 67 is formed of hardened steel or another magnetic material piece in the shape of a right cylinder having an outer diameter Q (for example, 50 mm), and holds a strong magnetism permanently.

FIG. 6 is a vertical cross-sectional view showing a feeding mode of the strip 26. With reference to FIGS. 3, 4 and 6, the magnetic roller 67 has a height R = 1.5 to 2.0 mm at which the outer surface of the magnetic roller 67 projects from the upper surface of the support member 37. , The tip of the support plate 70 of the peeling plate 66 is lower than the outer surface of the magnetic roller 67 when the cylinder 57 (see FIG. 1) does not operate and the rod 58 is retracted, but the cylinder 57 operates. Then, the downstream end of the peeling plate 66 in the belt-conveying direction is configured to project above the outer surface of the magnetic roller 67 by a height K (for example, about 5 mm).

Further, the dimensions of the respective parts shown in FIGS. 3, 4 and 6 are determined as follows, for example.

Width L of supporting member 37 = 200 mm Width L1 of guide member mounting window 55 in the direction of the pivot 65 = 158 mm Distance between supporting plates 70 of peeling plate 66 M = 36 mm Thickness of supporting plate 70 N = 12 mm Supporting plate 70 and magnetic roller 67 and the gap between the support member 37 and P = 1 mm In the guide member mounting window 55, the distance S between the end of the support seat 52 and the center of the pivot 65 in the direction orthogonal to the pivot 65 is the axis of the pivot 65. For example, the upstream side and the downstream side with respect to the vertical surface including 50 mm are each set to 50 mm, and the support seat 52 is prevented from being magnetized with a distance of 25 mm or more from the outer surface of the magnetic roller 67, and the covering on the downstream side of the window is prevented. The upstream end of the layer 53 is configured to be as close as possible to the magnetic roller 67 so that the gap between the layer 53 and the magnetic roller 67 is prevented from being caught by the tip of the strip 26. The downstream end of the coating layer 53 on the upstream side of the window is arranged with a gap such that the strip 26 can be guided onto the magnetic roller 67.

The operation of the guide device 21 will be described with reference to FIGS. 6 and 1 and 2 again.

The coil 25 is attached to the drum 24 of the uncoiler 23, the outer side of the coil 25 is pressed by the roller 29 of the coil pressing mechanism 28, and then the binding band is cut. After that, when the roller 29 is rotated in the arrow A1 direction by the motor 34 while the rotating torque on the side opposite to the arrow A4 direction is generated in the drum 24, the belt-shaped body 26 is gradually fed from the feeding position 36. At this time, the guide plate 37 of the guide device 21 is in a state in which the rod 81 of the cylinder 80 has been contracted in advance and angularly displaced in the direction of arrow C1.

As a result, the strip-shaped body 26 slides on the coating layer 53 and advances while curving along the shape of the support member 37. Here, when the band-shaped body 26 is relatively thick, such as when it is relatively thick, the tip of the band-shaped body 26 should be close to the coil 25 side, as in the winding portion 2a shown in FIG. 8 (1). And it becomes difficult to introduce it into the leveler feeder 27. Therefore, in this embodiment, in such a case, as shown in FIG. 6, the leading end of the strip 26 is guided to the guide plate 40 side so that it is guided to the vicinity of the inlet 39 of the leveler feeder 27. , While further advancing the strip-shaped body 26 while maintaining the state where the strip-shaped body 26 is attracted by the magnetic roller 67, the leading end of the strip-shaped body 26 successfully rides on the guide plate 40 and subsequently reaches the vicinity of the introduction port 39 of the leveler feeder 27. The cylinder 80 is operated and adjusted so that the support member 37 is angularly displaced.

As a result, the strip 26 follows the locus indicated by the arrow D1 in FIG. 6, and when the tip of the strip 26 comes into contact with the inner plate 41, the cylinder 44 is actuated and the roller 46 rolls the strip. 26 is pinched on the conveying roller 47 and introduced into the leveler feeder 27.

Since the magnetic roller 67 rotates, it does not hinder the progress of the magnetic roller 67 even if it comes into contact with the belt-shaped body 26.

The band-shaped body 26 conveyed to the leveler feeder 27 has a plurality of leveling rolls 49 whose straightening habits are corrected and is conveyed while being pinched by a pair of conveyance rollers 50. At this time, the rod 45 of the cylinder 44 is retracted in the arrow B3 direction, the roller 46 is angularly displaced in the arrow B5 direction, and the roller 46 is separated from the strip 26. Further, since it is not necessary to adsorb the strip 26 to the support member 37 by the magnetic roller 67, the cylinder 57 is operated to extend the rod 58 in the direction of arrow C4 prior to the retracting operation of the rod 45. Then, the peeling plate 66 is angularly displaced in the direction of arrow C6, and the strip 26 is pushed up by the end face of the peeling plate 66 on the downstream side in the transport direction of the strip, and the strip 26 is moved from the magnetic roller 67 as described above. They are separated and displaced so that the magnetic force does not reach the strip 26. It has been confirmed that about 5 mm is sufficient for this action.

The supply device 22 according to the present embodiment is mainly used for supplying the coil 25 having a coil width of 50 mm to 400 mm. Therefore, even when the coil with the minimum width is used, the width of the unwound strip is 50 mm. Therefore, when the peeling plate 66 is angularly displaced in the arrow C6 direction (see FIG. 6), at least one strip 26 is formed. It is pushed up by the support plate 70 and is reliably separated from the magnetic roller 67. Next, the rod 81 is extended and the support member 37 is lowered. This allows the strip 26 to form an appropriate loop below the drum 24.

Since the peeling plate 66 is made of stainless steel, magnetization is prevented and unwanted magnetic attraction of the strip 26 is prevented.

The strip-shaped body 26 forming the coil has a low rigidity due to, for example, a small plate thickness, and corresponds to the occurrence of the drooping portion 2b as described with reference to FIG. 8 (2) in the section of the prior art. Even when such a phenomenon occurs, the belt-like body 26 is introduced into the leveler feeder 27 through the procedure similar to that described above by activating the cylinder 80 in advance and angularly displacing the support member 37 in the arrow C2 direction. It is conveyed while being pinched by the conveyance roller 50. When guiding the band-shaped body 26 having a weak stiffness, the cylinder 57 may be operated to advance the time when the band-shaped body 26 is separated from the magnetic roller 67.

As described above, according to the present embodiment, regardless of the material and the plate thickness of the band-shaped body 26, only the angular displacement state of the support member 37 due to the operation of the cylinder 80 can be selectively adjusted to reach the leveler feeder 27. Can be introduced easily and automatically. Further, since the magnetic roller 67 is a permanent magnet, it is possible to reduce the size and simplification of the structure and to reduce the cost as compared with the case of using an electromagnet.

[0040]

[Effect of the device]

 As described above, according to the present invention, when the strip-shaped body is unwound and guided from the coil attached to the drum of the uncoiler, the strip-shaped body is magnetically adsorbed to the downstream end of the support member and the support member is vertically moved. By angularly displacing in the direction, the guide can be guided reliably and easily regardless of the strength of the band.

Further, a magnetic roller having a permanent magnetic force is used as the magnetic attraction means, and when the magnetic attraction becomes unnecessary, the strip-shaped body is pushed up by the peeling plate which is angularly displaced around the pivot axis of the magnetic roller, and the magnetic roller is pushed up. Since the strips are separated from each other, the structure is extremely simple, and therefore the size can be reduced, and the guide device can be provided at low cost.
