Description

Raver, steel sleeve drawer

The present invention relates to a device for inserting and withdrawing a rubber and steel sleeve, and more specifically, to automate the insertion and withdrawal work of a rubber sleeve and a steel sleeve mounted on a pay-off reel for steel sheet winding. In addition, the present invention relates to an improved lever and steel sleeve drawing device to minimize work time and improve work productivity.

In general, as shown in FIG. 1, a pay off reel 101 provided in a cold rolling facility of a steel mill may perform a mailing operation on a steel plate of a coil without damaging an inner diameter portion thereof. The inner diameter part is provided with a rubber sleeve (2) into which the inner diameter part is inserted, and the steel diameter part (3) is provided in the inner diameter part to obtain a coil in the inner diameter part of the coil produced by winding. Alternatively, when the surface and dimension defects are generated and the TJ product is wound again on the exit side after welding the steel plates of the wire and the trailing coil, the rubber sleeve 2 mounted on the payoff reel 101 is formed as shown in FIG. Only the sleeve 3 remains.

In this case, the steel sleeve 3 should be drawn out to the outside as a sleeve drawing device 100 as shown in FIG. When the inner diameter size is changed, the rubber sleeve 2 mounted on the payoff reel 101 according to the inner diameter size of the coil must also be replaced as the sleeve drawing device 100.

Meanwhile, as shown in FIG. 1, the conventional sleeve drawing device 100 includes a left and right clamp 120 mounted on both sides of the front end of the frame 110 so as to be rotatable thereto, and each inside thereof. A plurality of plates 121 mounted on and in contact with the outer surfaces of the sleeve members 2 and 3, an operation cylinder 130 for opening and retracting them, and safely inducing clamping of the left and right clamps 120; As the induction gear 122 is configured, when the lead-out reel 101 is to be withdrawn and inserted to replace the rubber sleeve 2 mounted, the left and right clamps 120 are clamped to the rubber sleeve 2. After close to the outer circumference of the outer peripheral surface, when the operating cylinder 130 is operated to retract the left and right clamp 120, both sides of the plate 121 is in close contact with the outer surface of the cylindrical rubber sleeve (2) It was clamped and taken out. In this case, since the roundness of the rubber sleeve 2 and the plate 121 contacted by the clamping operation do not coincide with each other, sliding occurs at the contact surface of the rubber sleeve 2 during the drawing and inserting operation, making it difficult to draw out. There was a problem.

In addition, in the case where the steel sleeve 3 to be pulled out at the position of the rubber sleeve 2 is to be withdrawn, the steel sleeve 3 has the upper portion of the rubber sleeve (inner circumferential surface) due to its own weight as shown in FIGS. 1 and 2. On the other hand, since the lower end of the inner circumferential surface is spaced apart to generate the clearance T, as described above, the steel as a left and right clamp 120 that is operated by pinching operation by operating the operation cylinder 130 as described above. When the sleeve 3 is pulled out, there is a problem that the steel sleeve 3 and the rubber sleeve 2 in contact with the upper inner circumferential surface are also drawn out.

In this case, it is accompanied by the cumbersome work of re-mounting the labyrinth (2) pulled out by the worker to the pay-off reel 101, there is a possibility of occurrence of acid disaster due to the manual increase There was a problem in reducing the work efficiency by delaying time.

Therefore, the present invention has been devised to solve the above problems, and its purpose is to remove and insert the rubber sleeves mounted on the payoff reel and the steel sleeves remaining thereon more safely and quickly. By automating so that it can be done automatically, it will shorten the downtime of the facility to improve the work efficiency, and to provide a lever, steel sleeve withdrawal device that can eliminate the risk of safety accidents.

As shown in FIGS. 2 to 4, the rubber and steel sleeve drawing device 1 according to the present invention has a rubber sleeve 3 mounted on the payoff reel 101 and a steel sleeve 3 remaining thereon. Withdrawal, insertion can be performed quickly and simply without manual operation to reduce the equipment down time, such an apparatus 1 is composed of a first touch portion 10 and a second touch portion (20).

That is, the first touch part 10 mounted at the center of the front end of the frame 110 in which the left and right clamps 120 are rotatably installed has a first fixing stand 11 having a perforated insertion hole 11a at the center of the upper surface thereof. It is provided, between the plurality of cylinder holder 13a installed to face the upper surface of the first fixing 11, the rear is installed so as to replace the upper and lower cylinder 13 is inserted into the insertion hole (11a), the upper surface It is equipped with the slider 12 which is mounted so that the guide protrusion 14 of the movable base 16 mentioned later may move up and down. In addition, the movable table 16 mounted on the rod end of the upper and lower cylinders 13 to be operated up and down has a mounting hole l6a in which a plurality of electromagnets 15 for generating magnetic force when the external power is applied to the upper surface are fixed. The lower both side surfaces are provided with guide protrusions 14 assembled to the slider 12, respectively.

In addition, the first contact plate 17 having the thread 17a formed on the upper surface having the curvature is installed as a screw member 16b in front of the movable table 16, and moved together with the lever, steel sleeve ( 2), (3) in contact with the outer surface, the guide protrusion 14 of the movable table 16 is provided with a touch rod 18, one side of the slider 12 of the touch rod 18 The upper and lower sensor members 19a and 19b are respectively provided to detect the vertical position.

In addition, the second touch unit 20, which is in contact with the outer surfaces of the lever, steel sleeve 2, and 3 together with the first touch unit 10, has an operation cylinder 130 mounted to the frame 110. Equipped with a plurality of second fixing stand 21 in the inner side of the left and right clamp 120 to be retracted or opened during operation, the upper surface of the second fixing stand 21 can be mounted to mount the electromagnet 22 And a second contact plate 24 screwed with the tip of a fixing pin 23 having a spring member 23a in the body, and a second contact plate 24 in front of the ball 21a. Like the first contact plate 17, the thread 24a is formed on the upper surface having the curvature to prevent the sliding of the cylindrical rubber, steel sleeves 2, and 3 at the same time.

In order to withdraw the steel sleeve 3 remaining on the rubber sleeve 2 mounted on the payoff reel 101 by using the above-mentioned rubber, steel sleeve drawing device 1, first, the frame 110 is used. The left and right clamps 120 rotatably mounted on the rotating shaft 111 of the steel sleeve 3 while stopping in the open state near the center of the outer surface of the steel sleeve 3 and at the same time. When the upper and lower cylinders 13 installed are moved upward, the guide protrusions 14 of the movable base 16 connected to the rod end are slid to the upper portion along the fitted slider 12, and the front and rear cylinders 13 are mounted in front of the movable base 16. At the same time, the first contact plate 17 is lifted to the upper portion at the same time to raise the steel sleeve 3 so that the steel sleeve 3 sagging downward due to its own weight and the rubber sleeve 2 in contact with the upper end thereof are separated from each other. Let's do it. At this time, when the touch rod 18 of the movable table 16 that moves upwardly comes into contact with the upper sensor member 19a mounted inside the slider 12, the lifting operation of the upper and lower cylinders 13 is stopped. Ascending movement of the first contact plate 17 is stopped.

Subsequently, when the operation cylinder 130 is operated to retract the left and right clamps 120 which are in an open state and the plurality of second contact plates 24 mounted on the outer circumferential surface of the steel sleeve 3 come into contact at the same time, the second fixing plate ( The second contact plate 24 fitted into the through hole 21b of the 21 and screwed to the tip of the fixing pin 23 having the spring member 23a is pushed backward while contracting the spring member 23a. When stopped in contact with the second fixing stand 21. Accordingly, the first and second contact plates 17 and 24 having the threads 17a and 24a on the upper surface having the curvature are located inside the steel together with the elastic restoring force of the spring member 23a. The slab 3 can be reliably clamped as the left and right clamps 120 so that they can be pulled out. In addition, when an external power source is applied to generate a magnetic field to the electromagnets 15 and 22 installed in the mounting holes 16a and 21a of the movable table 16 and the second fixing table 21 in such a clamping state. In addition, since the magnetic field is also extended to the first and second contact plates 17 and 24 adjacent thereto, a clearance is formed between the inner circumferential surface of the steel sleeve 3 and the outer circumferential surface of the rubber sleeve 2 that are in contact with the inner surface thereof. The steel sleeve 3 can be safely taken out to the outside without simultaneous release of the rubber sleeve 2 as in the prior art.

In addition, when the steel sleeve 3 is drawn out from the payoff reel 101, the external power is cut off so that the magnetic fields of the electromagnets 15 and 22 are not generated, and the operation cylinder 130 is lowered. The left and right clamp 120 is opened and at the same time, the upper and lower cylinders 13 connected to the upper and lower cylinders 13 are connected to the lower sensor member l9b so that the movable table 16 that is raised is lowered and returned to its original state. It is possible to end all the drawing operations of the steel sleeve 3 by lowering the operation until it comes into contact with the stop.

On the other hand, when replacing the rubber sleeve (2) in which the inner diameter is fitted due to the change in the inner diameter of the coil, as in the above, first stop the left and right clamps 120 close to the outer surface of the rubber sleeve (2) in the open state. At the same time, the operation cylinder 130 is operated again to close the left and right clamps 120 so that the rubber sleeve 2 can be clamped.

In this case, the plurality of second contact plates 24 mounted inside the left and right clamps 120 are in contact with the outer circumferential surface of the rubber sleeve 2 at the same time, and the left and right clamps 120 are retracted in a contact state. As it proceeds, the second contact plate 24 is fitted into the through hole 21b of the second fixing stand 21 and screwed to the tip of the fixing pin 23 having the spring member 23a. While contracting 23a), it is pushed back until it comes into contact with the front surface of the second fixing stand 21 and stops.

Accordingly, the second contact plate 24 made of a rubber member and the cylindrical rubber sleeve 2 is in close contact with the outer surface thereof together with the elastic restoring force of the contracted spring member 23a, and has a thread 24a. Since it is clamped by reliably, the said rubber sleeve 2 can be taken out safely and quickly without slipping outside. In addition, the insertion work to the rubber sleeve may be performed in the reverse order.

Therefore, according to the present invention, the first contact plate 17 and the plurality of electromagnets 15 and 22 which are operated up and down by the upper and lower cylinders 13 are provided to facilitate the withdrawal of the downwardly deflected steel sleeve 3. And 1,2 contact plates 17 and 24 protruding the threads 17a and 24a on the curved upper surface for easy removal and insertion of the rubber sleeve 2, as in the prior art. The steel sleeve 3 can be easily and quickly pulled out without simultaneous release of the rubber sleeve 2, and the rubber sleeve 2 can be pulled out without slipping even if the outer diameter of the rubber sleeve 2 is damaged by the coil inner diameter. Since the incoming work can be automated, the work time can be shortened, the manual work can be reduced, and the downtime of the equipment can be shortened to improve the work efficiency.
