Description

Automatic Sheet Removal Device {Device for removing the paper from stainless steel strip}

The present invention relates to a device for automatically taking out a sheet of paper wrapped around the inside of a stainless cold rolled coil, and more particularly, a spool to wind the sheet of paper is unnecessary, thereby achieving convenience in use, and automatically drawing out a sheet of paper. The present invention relates to an automatic sheet taking-off device which has been improved to significantly reduce work load and greatly improve work productivity.

In general, in the stainless steel cold rolled steel sheet production equipment 100 of the steel mill, in order to prevent friction defects on the surface of the material due to the tension generated during cold rolling of the stainless steel cold rolled steel sheet (hereinafter referred to as a strip) The winding is made by inserting 110, and the stainless cold rolled coil (strip) into which the slip sheet 110 is inserted is released from the payoff reel 120, and the strip S and the slip sheet 110 are separated, and the strip ( S) proceeds to a separate line for the subsequent process, and the slip sheet 110 separated from the strip S is wound to the winding mechanism 135 of the slip sheet extraction device 130.

Related to the above, a conventional slip sheet extractor 130 is shown in FIGS. 2 and 3. The conventional slip sheet extracting device 130 is provided with a winding mechanism 135 which rotates by pneumatic pressure, and the winding mechanism 135 is fitted with a cylindrical spool 140, and then the slip sheet 110 is wound onto the spool 140. In this case, the winding mechanism 135 rotatable by the pneumatic motor has the following structure. That is, the conventional winding mechanism 135, as shown in Figure 3, is equipped with a rubber tube 150 expandable by pneumatic inside the hollow casing 137, the casing 137 a plurality of expansion Pins 160 are to be mounted. The expansion pins 160 form a substantially cylindrical shape and are fitted in a plurality of holes 137a formed in the casing 137, and each lower end has a base 162 contacting the rubber tube 150. Therefore, when air is not injected into the winding mechanism 135 as described above through the pneumatic circuit 170 as shown in FIG. 2, the rubber tube 150 protrudes radially outwardly of the casing 137. Since the length of the expansion pin 160 is not large, the operator can insert the cylindrical spool 140 into the casing 137, and after the insertion is completed, to inject pneumatic pressure into the rubber tube 150 As a result, the plurality of expansion pins 160 extend radially outwardly of the casing 137 to be in close contact with the inner circumferential surface of the spool 140 and to expand the spool 140 to be fixed to the casing 137.

The pneumatic circuit 170 may be provided with a pneumatic storage tank (not shown) and a pneumatic pump (not shown) to provide a set pneumatic, and a line (not shown) and a valve for connecting the pneumatic to each mechanical element ( Not shown).

Then, in the state in which the spool 140 is mounted on the casing 137 as described above, the front end of the slip sheet 110 is drawn out and wound on the spool 140, and the pneumatic motor 200 is continuously rotated, as shown in FIG. As described above, the slip sheet 110 drawn from the strip S is wound on the spool 140 and taken out. In addition, when the winding of the slipper 110 is completed on the spool 140, if the pneumatic pressure is removed from the rubber tube 150 differently from the above, the spool 140 is loosely maintained in the casing 137 so that workers The slip sheet 110 and the spool 140 are withdrawn from the casing 137 and a new spool 140 is mounted to prepare for the next job.

However, the conventional slip sheet extractor 130 as described above should use a spool 140 of a material different from the cylindrical slip sheet 110 material for winding the slip sheet 110, and this spool 140 The removal work of the spool 140 has a problem that the recovery operation of the spool 140 is not easy because it must be separated and reused from the slip paper 110 during the removal of the slip paper 110. Therefore, a lot of time is required during the disposal process of the slip sheet 110, the work productivity is lowered, causing a problem of cost increase by the spool 140. In addition, since the work to remove the spool 140 wound around the slipper 110 from the take-up mechanism 135 is performed by the worker's manual work, the work load of the worker is increased, resulting in various safety accidents and industrial accidents. .

The present invention is to solve the conventional problems as described above, the purpose is to eliminate the need for a spool (spool) to wind the slip sheet to achieve the convenience of pulling out the slip sheet, and by using the pneumatic to automatically pull out the slip sheet The purpose of the present invention is to provide an improved automatic sheet taking out device to reduce the work load and prevent worker safety accidents as well as to greatly improve work productivity.
