Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic exchanging device for a slitter line separator.

[0002]

2. Description of the Related Art For example, Japanese Utility Model Laid-Open No. 1-127609 discloses a separator for a strip slitter. This separator is a device that appropriately separates slit materials so that they do not overlap each other when a plurality of slit materials are cut out from one coil by a slitting machine called a slitter.

FIG. 8 is a principle diagram of a slitter line, in which a wide coil 101 is sent from a left side to a right side of the drawing at a predetermined speed.
The slitter 102 cuts the strips. After slitting, the slit material 103 is appropriately processed in parallel by the separator 110, and then wound on the tension reel 105 via the tension pad 104.

FIG. 9 is a view showing a conventional separator,
The separator 110 has a thin disk 11 on the arbor shaft 111.
2 ... (... indicates a plurality; the same applies hereinafter), and the wire 114 is used when changing the width of the slit material.
It is lifted up by the crane hook 115 using the above and is replaced with another separator not shown.

[0005]

The frequency of replacement of the above separator is, for example, 10 times per day, which is extremely frequent. The slitter line is stopped during this replacement. Further, as explained with reference to FIG. 9, since the replacement is performed by slinging with a human hand as a main element, the replacement time becomes long, and it is expected that the mounting accuracy varies or deteriorates. Therefore, conventionally, there has been a decrease in the operating rate of the slitter line and an increase in the burden on the worker, and countermeasures against this have been desired. Therefore, an object of the present invention is to provide a separator exchanging device capable of automatically and promptly exchanging a separator.

[0006]

SUMMARY OF THE INVENTION To achieve the above object, the present invention provides a separator truck that mounts a separator and reciprocates in and out of a slitter line, and a separator on the separator truck that is arranged outside the slitter line. A separator exchanging device for a slitter line is configured from a separator collecting and supplying mechanism that collects and supplies another separator to a separator carriage.

The separator cart may be capable of mounting two separators.

Further, the separator truck is provided with an elevating means capable of changing the height position of the separator. Further, it is preferable that the separator trolley is provided with a steady rest fitting that engages with the fixed-side receiving fitting to prevent steadying when the separator is raised to the operating height.

On the other hand, the separator collecting and supplying mechanism has a swivel head for supporting the new and old separators in a cantilever manner, a horizontal shaft for rotating the swivel head around a horizontal axis, and a horizontal shaft for rotating the horizontal axis. And a swivel head elevating means for elevating and lowering the swivel head.

Further, it is preferable that the separator collecting / supplying mechanism is provided with two swiveling heads so that four separators can be supported by a cantilever at the same time.

[0011]

[Operation] The separator is placed on the separator truck, and in this state, the slit material is separated on the slitter line. When replacing the separator, the separator cart is pulled out, the separator above it is recovered by the separator recovery supply mechanism, and a new separator is supplied.

By placing the two separators on the separator truck, the two separators are replaced in one shift.

The separator on the separator carriage is passed down through the tip of the slit material. After that, it may be raised to the normal operating height and maintained. At the operating height, the runout of the separator is prevented by engaging the steady rest with the receiving fitting on the fixed side.

The separator collecting / supplying mechanism causes the swivel head to grip the old and new separators, raises them to a position where they do not hit the separator carriage, then reverses them so as to replace the positions of the old and new separators, and then mounts the new separators on the separator carriage. .

By providing two swivel heads, two separators can be replaced in one shift.

The same applies hereinafter) and #. The separator recovery and supply mechanism 30 replaces the two separators 3N. The separator truck 10 runs on the four rails 6 at right angles to the slitter line SL. The separator exchanging device 1 of this embodiment is a so-called twin type exchanging device.
It is a device that can replace the 1 separator 2 and the # 2 separator 3 at the same time.

FIG. 2 is a side view of the slitter line separator exchanging device according to the present invention. A drive unit 7 (correctly # 1 separator 2 and # 2 separator) for reciprocating a separate carriage 10 is provided beside the rail 6. For each of the three, one is provided for each, but a total of two are provided, but for the sake of convenience, the description for the # 1 separator 2 will be described. The same applies to the following.) The separator collecting / supplying mechanism 30 is installed in the above. Hereinafter, the structures of the separator cart 10 and the separator collecting / supplying mechanism 30 will be described in detail.

FIG. 3 is an exploded perspective view of the separator truck according to the present invention. The separator truck 10 has a truck frame 12 provided with shoes 11 that are in sliding contact with the rails 6 and the elevator truck 12 as a lifting means. Cylinder 13,
13 and a guide 14, and an elevating frame 15 supported by an elevating mechanism, and a pillow member 16 mounted on the upper surface of the elevating frame 15 to receive a separator neck. In the figure, 17 is a chain stopper, 18 is a steady stopper, and 21 is a positioning plate with a tapered hole 19. Further, 23 is a carriage positioning cylinder, and 24 is a support for the cylinder 23.

The separator 2 has a plurality of disks 2b ... Attached to an arbor shaft 2a, and bearings 2c, 2c fitted to both ends of the arbor shaft 2a. The separator 3 is also the same.

FIG. 4 is an exploded perspective view of the separator recovery / supply mechanism according to the present invention. The separator recovery / supply mechanism 30 is a stand 31 constructed by bonding a shaped steel and a plate together.
And the vertical rail 3 attached to the side of this stand 31
2, a slider 33 that moves up and down, a horizontal shaft 35 rotatably supported by the slider 33 via bearings 34, 34, and a swivel head 36 fixed to the tip of the horizontal shaft 35. The separator end fitting holes 37 and 38 formed in the swivel head 36, the pinion 39 for rotating the horizontal shaft 35, the rack 41, and the rotation cylinder 42 as the horizontal shaft rotating means, and the swivel head 36. It comprises a swivel head elevating means (for example, an elevating cylinder) 43 for elevating. Although the mechanism for the # 1 separator has been described with reference to FIG. 4, the mechanism for the # 2 separator is also attached to the one-set stand 31 as illustrated. The reference numerals are used for these, and the description of the configuration is omitted.

The operation of the separator exchanging device having the above structure will be described below. Although the # 1 separator and the # 2 separator are replaced at the same time, only the # 1 separator will be described here for the sake of simplicity. For convenience, the # 1 separator 2 is referred to as “old separator 2” and the # 1 separator 2N is referred to as “new separator 2N”. FIG. 5 (a)-
(D) is explanatory drawing which shows the first half process of the separator exchange work of this invention. When replacing the old separator 2 to be replaced shown in (a), the separator truck 10 on the separator line SL is pulled out in the arrow direction. The next new separator 2N is set in advance in the separator end fitting hole 38 of the swivel head 36. (B) is the old separator 2
Shows one end of the rotary head 36 fitted into the other separator end fitting hole 37 of the swivel head 36.

In (c), the slider 33, that is, the new and old separators 2N, 2 is first raised by the lifting cylinder 43 to a predetermined high position. This is because the old separator 2 needs to be sufficiently separated from the separator truck 10. Next, at this high position, the swivel head 36 is rotated 180 ° by the rotating cylinder 42 to replace the new and old separators 2N, 2 with each other. In (d), the lifting cylinder 43 is retracted, the new and old separators 2N, 2 are lowered, and the new separator 2N is placed on the separator truck 10.

6 (a) and 6 (b) are explanatory views showing the latter half of the separator replacement work of the present invention. In (a), the separator carriage 10 on which the new separator 2N is placed is moved in the direction of the arrow, and is centered on the separator line SL. In (b), the wedge-shaped rod of the positioning cylinder 23 is inserted into the positioning plate 21 of the separator truck 10. As a result, the separator truck 10 is accurately positioned, and at least the separator truck 10 does not move in the left-right direction in the drawing. Further, when the operation level includes the separator 2 or 2N, the steady rest metal fittings 18 ... Are engaged with the stationary metal fittings (described in detail in FIG. 7). As a result, the separator 2 or the 2N separator line SL does not move in the direction of SL.

On the other hand, the old separator 2 held by the turning head 36 is removed by a crane or the like while the separator truck 10 is on the separator line SL, and the turning head 36 holds a new separator 2NN. Just do it. The replacement work of the # 1 separator has been described above.
The replacement work of the two separators is similar, and since the apparatus of this embodiment is a twin type, it is characterized in that the # 1 and # 2 separators can be replaced at the same time by one shift. Of course, it is safe to replace only one separator in this twin type device.

Next, the operation of the lifting mechanism of the separator truck will be described. 7 (a) and 7 (b) are operation diagrams of the separator truck according to the present invention, and show the case where the slit material 103 travels from the left to the right in the figure. (A) shows a state in which the # 1 and # 2 separators 2N and 3N are retracted downward. The tip 103a of the slit material 103 is much more easily deformed than other portions. When the greatly deformed tip 103a collides with the disk 2b of the # 1 separator 2N, a loud metallic sound is generated and the disk 2b is further scratched. Therefore, the lifting cylinders 13 ... Are retracted to retract the lifting frame 15 and the separators 2N and 3N downward.

After the tip has passed, the lifting frame 15 and the separators 2N and 3N may be raised to the operating position as shown in (b). After that, the slit material 103 is not separated by the separators 2N and 3N and there is no fear of overlapping. During operation, as shown in (b), the anti-sway metal fittings 18 on the elevating frame side are tightly engaged with the receiving metal fittings 45 on the fixed side.

The elevating means 13 may be any means such as a hydraulic cylinder, an electric cylinder, a pinion / rack mechanism, a link mechanism such as a pantograph, etc., and is basically a means for moving the separator between the operating position and the retracted position. I wish I had it. Similarly, the horizontal shaft rotating means 42 may be a mechanism that rotates the horizontal shaft 35 by a predetermined angle, and the swivel head elevating means 43 may be a hydraulic cylinder, an electric cylinder, or a pinion as long as it is a mechanism that elevates and lowers the swivel head 36 to a predetermined height. A rack mechanism or a combination thereof may be used, and the mechanism is arbitrarily selected.

Further, although the swivel head elevating means 43 is constructed so as to elevate the horizontal axis rotating means 42 together with the swivel head 36 in the embodiment, the invention is not limited to this. The horizontal shaft rotating means 42 in the non-elevating state and the swivel head 36 may be connected by a universal joint. As described above, according to the present invention, it is optional whether or not other related components are moved up and down when at least the swivel head 36 is moved up and down.

[0029]

Since the present invention is constructed as described above, it has the following effects. The separator exchanging device according to claim 1 is composed of a separator carriage and a separator collecting and supplying mechanism, the separator is mounted on the separator carriage, and in this state, the slit material is separated on the slitter line,
When replacing the separator, pull out the separator truck, collect the separator above it with the separator recovery supply mechanism, and supply a new separator, so the replacement of the separator is automated and the burden on the worker involved in the replacement work is greatly increased. It is reduced to. Further, since the separator can be set on the slitter line while being placed on the separator truck, the separator can be quickly replaced without the conventional sling and crane, and the slitter line stop time accompanying the replacement can be greatly shortened.

Since the separator truck according to claim 2 can mount two separators, it is possible to replace two separators in one shift, which is suitable for a slitter line having a plurality of separators.

The separator truck according to claim 3 is provided with an elevating means capable of changing the height position of the separator, and the separator can be retracted when the tip of the slit material passes, so that the tip of the slit material collides with the separator. It is possible to prevent the collision noise and the accompanying flaws from occurring. Also, although it was difficult in the past, according to claim 3, the separator can be easily adjusted by lowering the separator. For example, the disk interval can be changed, and this degree of adjustment can be performed on the slitter line. Therefore, the operating rate of the slitter line can be further increased.

The separator cart of claim 4 is provided with a steady rest, and the steady rest can be engaged with the receiving fitting on the fixed side at an operating height, so that the runout of the separator during operation can be prevented.

A separator recovery and supply mechanism according to a fifth aspect of the present invention includes a swivel head for cantileverly supporting the new and old separators,
A horizontal axis for rotating the swivel head around a horizontal axis, a horizontal axis rotating means for rotating the horizontal axis, and a swivel head elevating means for at least elevating the swivel head. The swivel head holds new and old separators. Then, it rises to a position where it does not hit the separator truck, then reverses to replace the positions of the old and new separators, and then puts the new separator on the separator truck, so that the separator on the separator truck can be replaced automatically and quickly. The burden on workers and the efficiency of work can be improved.

Since the separator collecting and supplying mechanism of claim 6 has two swiveling heads, two separators can be replaced by one shift, which is suitable for a slitter line having a plurality of separators.
