Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a separator device for separating each slit coil, for example, when coils slit to a predetermined width are wound onto a recoiler.

During slitting work, when winding slit coils onto a recoiler, the slit coils are separated using a separator device to create a certain gap between each slit coil, and the coils are continuously wound while being pressed against the recoiler mandrel. ing.

The conventional separator device inserts a ring-shaped separator roll and a spacer around the outer circumference of the separator shaft, sets the spacing between the separator rolls by the combination of the spacers, and tightens a nut from the end of the shaft. The separator roll and spacer are fixed to the shaft. When changing the slit width of the coil, the spacing between the separator rolls must also be changed at the same time, but to do this, the entire separator shaft must first be removed from the separator stand, and then reassembled separately from the slit line using a transport cart. The procedure is to transport the product to a location, remove the separator roll and spacer that have been inserted through the shaft, install a new separator roll and spacer, and then transport the product to the separator stand again using a transport cart.

Therefore, to change the slit width, the separator roll and spacer must be removed from the shaft and inserted, which is extremely complicated, and the change cannot be completed in time outside the line, resulting in line stoppages. This resulted in a decline in line operating rates.

In addition, since the change work is performed outside the line, personnel other than line operators and a large work space are required.

Furthermore, equipment costs were high because it was necessary to prepare a crane to transfer the separator shaft to a transport truck and to prepare many types of spare spacers according to variations in slit width.

In addition, one end of the separator shaft is used as a reference surface, and the spacing between the separator rolls is adjusted by combining multiple spacers, so if there are variations in the insertion of the spacers, a large error will occur in the spacing between the separator rolls. However, it was difficult to adjust the slit width accurately.

The present invention has been made in view of the various drawbacks mentioned above, and its first purpose is to eliminate the work of removing and inserting separator rolls and spacers when changing the slit width, and to quickly change the slit width within the line. The objective is to obtain a separator device that can be used. The second object is to obtain a separator device that does not require personnel other than line operators or a large working space. The third object is to obtain a separator device that does not require a crane or a spacer. Furthermore, the fourth
The purpose of this invention is to obtain a separator device in which the spacing between separator rolls can be set accurately.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the accompanying drawings, which are examples of the present invention.

1 to 6 show a first embodiment of a separator device according to the present invention. In FIG. 1, 1 is a recoiler mandrel, and 2 is a slit coil wound around the recoiler mandrel. 3 is a pivot shaft rotatably supported by a stand 4; 5 is a pair of arms fixed to the pivot shaft 3; the arms 5 rotatably support both ends of a separator shaft 6 constituting a separator device; are doing. When replacing the separator shaft 6, changing the slit width, or taking out the slit coil 2 wound around the recoiler mandrel 1, the arm 5 is rotated as shown by the dashed line in the figure.

As shown in FIG. 3, the separator shaft 6 is provided with guide grooves 7 in the axial direction and over the entire length at 180° symmetrical positions on the outer circumferential surface, and an insertion hole penetrating diametrically at the bottom of the guide groove 7. 8 is provided. Two guide grooves 9 having no insertion holes are provided in the axial direction at positions separated by 90 degrees from the guide groove 7. Incidentally, a scale 10 (see FIG. 2) is provided on the outer peripheral surface of the separator shaft 6 as necessary.

Reference numeral 11 denotes a separator roll (see FIG. 4) made of a ring-shaped thin metal plate, and this separator roll 11 can freely slide on the outer periphery of the separator shaft 6, and has the guide grooves 7 and 9 on its inner periphery. Projecting portions 12 and 13 are provided to slidably engage with each other.

14 and 17 are slide blocks that slidably fit into the guide groove 7 (see Figures 5 and 6).
The outer peripheral surfaces of these slide blocks 14 and 17 are curved with the same curvature as the outer peripheral surface of the separator shaft 6. One slide block 14 has a screw seat 15 for a tightening bolt 19 and a bolt insertion hole 16, and the other slide block 17 has a screw hole 18 into which the tip of the tightening bolt 19 is screwed.

The separator roll 11 has convex portions 12,
13 is inserted from the end while being engaged with the guide grooves 7 and 9 of the separator shaft 6, the slide blocks 14 and 17 are fitted into the guide groove 7 so as to be located on both sides of the separator roll 11, and the tightening bolt 19 It is temporarily fixed by loosely screwing it together. To fix the separator roll 11 at a desired position, slide the separator roll 11 to the desired position on the scale 10, and move the slide blocks 14, 17 onto the protrusion 12 of the separator roll 11.
By sliding the slide blocks 14 and 17 to the position where they abut against both sides of the separator roll 11 and tightening the tightening bolts 19, the slide blocks 14 and 17 are fixed to the bottom of the guide groove 7, and both sides of the protrusion 12 of the separator roll 11 are sandwiched. Pressure fix. Thereby, the separator roll 11 is accurately positioned and fixed.

When changing the slit width, tighten the tightening bolt 1.
9, slide the separator roll 11 and slide blocks 14, 17 to set them at desired positions, and then tighten the tightening bolt 19.

If there is sufficient space to install the separator device, both ends of the separator shaft 6 can be extended laterally from the recoiler mandrel 1, and a spare separator roll 11' can be accommodated in this extension 6a as shown in FIG. You can leave it as is. and,
If the slit width becomes narrower and more separator rolls 11 are required, use a spare separator roll 1.
1' may be used by sequentially pulling them out from the extension portion 6a.

In the above embodiment, one separator roll 11
A total of 4 slide blocks 1 to secure the
4 and 17 are used, but the slide block 14 having the bolt insertion hole 16 may be omitted. Also,
In addition to the guide groove 7 having an insertion hole 8, a guide groove 9 without an insertion hole is provided in the separator shaft 6 so that the separator roll 11 is guided at four locations. It can be stably moved relative to the separator shaft 6. Furthermore, R surfaces 7a and 9a are provided on both side edges of the guide grooves 7 and 9 (see Fig. 3), so that when the coil 2 is pressed against the mandrel 1 and wound up, the coil 2 is There is no risk of damage caused by the side edges of the guide grooves 7 and 9.

FIG. 7 shows a second embodiment of the present invention, in which both sides of a guide groove 7 provided in a separator shaft 6 are tapered surfaces 7a which are narrower on the outer peripheral surface side, and correspondingly, slide blocks 14, 17 are formed. Both side surfaces are tapered surfaces 14a and 17a. This eliminates the fear that the slide blocks 14 and 17 will fall off the guide groove 7, and makes it easier to fix the separator roll 6. Also, since the width of the opening of the guide groove 7 is narrowed, the side edges Damage to the coil 2 can be prevented even without providing an R surface.

FIG. 8 shows a third embodiment of the present invention, in which slide blocks 14 and 17 are integrally fixed or engaged with the side surfaces of the protrusion 12 of the separator roll 11. Two slide blocks 1 are used to fix the roll 11.
4 and 17, and the fixing of the separator roll 11 becomes even easier.

In addition, the separator device according to the present invention is used not only as a separator that is used to press the coil onto the mandrel when winding the slit coil around the recoiler mandrel as described above, but also as a separator that prevents the coil from forming between the tension roll and the recoiler. It can also be applied to auxiliary separators to prevent meandering.

As is clear from the above description, according to the present invention, when changing the slit width, the tightening bolt is loosened and the separator roll and slide block are slid to position them at the desired position, and then the tightening bolt is loosened. All you have to do is tighten it, and there is no need for the troublesome work of removing and inserting the separator roll and spacer as in the past. Furthermore, since this modification work can be carried out within the line while the separator shaft is placed on the stand, the work time can be greatly shortened and the line operating rate will not be reduced. Furthermore, this eliminates the need for personnel other than line operators and a large work space. In addition, since the slit width can be changed manually, a crane is not required, and many types of spare spacers are also not required, leading to a significant reduction in equipment costs. In addition, the spacing of the separator rolls can be set by measuring and fixing the spacing of the separator rolls individually, which eliminates the troublesome work of calculating from the reference plane at the end of the separator shaft as in the past. This has the effect of making it possible to set the interval accurately.
