Description

Sheet feeder {SHEET FEEDING APPARATUS}

The present invention relates to a sheet supply apparatus, and more particularly, to a sheet supply apparatus for supplying a sheet more effectively by removing static electricity.

In general, a rolled steel sheet (hereinafter referred to as a 'strip') is rolled up on a coil after removing the scale layer through annealing and pickling lines. In order to protect the surface of the strip to be wound, a sheet of paper (eg a vinyl sheet or a paper sheet) is inserted between the strips.

Particularly, if the strip is made of stainless steel, it is essential to insert a sheet of paper because of its fine surface and high value-added product. In the winding process of the strip, the strip and the slippery must maintain a constant tension to prevent wrinkles on the stripe and prevent defects due to contact between the strip and the friction. As described above, the strip winding facility for winding the strip is provided with a slip sheet supplying device for supplying slip sheets.

In order to smoothly insert the interlude between the strips by the interlude feeder, the process of inserting the tip of the interlude between the coils must be smooth. However, in the process of inserting the slippers between the strips, the weight of the slippers is small and the static electricity is generated, the operator has a problem of increasing the load of the work by inserting the end by inserting the jig into the jig. Therefore, there is a problem in that productivity decreases due to delayed insertion of the exit sheet.

On the other hand, the conventional method of removing static electricity to remove the static electricity generated in the kanji is to increase the humidity around the kanji to suppress the generation of static electricity, or there is a method of static electricity by installing a static eliminator. This is a very inefficient method of drawing the interlude sticking between the coils depending on the operator and inserting it between the coils.

If the antistatic work is carried out in this way, delays in the release of ice sheets will result in safety disasters due to productivity drop and instability. In addition, there is a problem that damages the health of workers by exposure to static electricity.

Here, the antistatic bars 111 and 112 and the air nozzles 115 and 116 are formed to have the same length and are fixed by the support members 113 formed at both ends.

The air nozzles 115 and 116 may be installed to extend in the extending direction of the antistatic bars 111 and 112 in a tubular shape having a predetermined length, gas may be introduced into the air nozzles, and an injection hole may be formed at a lower side thereof to inject gas.

Referring to FIGS. 6A and 6B, the support member 113 may be formed as a plate having a predetermined thickness having a rectangular cross section. This may be divided into four areas when viewed from the front, and the first static charge bar 111 may be formed in the upper left region and the second static charge bar 112 may be formed in the right region. In addition, a first air nozzle 115 may be formed in the lower left region, and a through hole through which the air supply pipe 114 may be connected may be formed on the outer surface of the region. A second air nozzle 116 may be formed in the lower right region, and a through hole through which the air supply pipe 114 may be connected may be formed on the outer surface of the region.

As shown in FIG. 6 (c), the first static charge bar 111 and the second static charge bar may have a polygonal cross section and may have a polygonal pillar extending in the width direction of the sheet 500. have. In this case, the shape of the cross section may be formed in various shapes without being limited to any one. Specifically, the cross section may be formed in the shape of a rectangle.

Here, the first static charge bar 111 and the second static charge bar 112 remove static electricity of the sheet 500 unwound from the sheet coil part 400. As shown in FIG. 1, the sheet 500 unwound and supplied from the sheet coil unit 400 passes between the sheet feed rolls 210 and 220 and the static eliminator 110 and is placed on the sheet feed rolls 210 and 220. In this case, when the sheet 500 is supplied from the first sheet 410, static electricity is generated on the sheet 500. This static electricity can be removed by the first antistatic bar.

In general, a method for removing static electricity can be divided into light irradiation and corona discharge according to a method of separating air molecules. The light irradiation uses a kind of X (X) rays, which are much weaker than Renten, to decompose molecules in the air and generate a large amount of air ions. The characteristic of the light irradiation type is that the air in the part where the X (X) line touches can be decomposed into ions and can be charged. For this reason, a wider range of static elimination is possible than the corona discharge type static elimination described later. On the other hand, corona discharge is an antistatic method that occurs when a high voltage is applied to a sharp part of a fiber, a wire, a needle, or the like. When a corona discharge occurs, discharged electrons collide with air molecules to generate air ions. In particular, self-discharge during corona discharge is a method of generating a corona discharge at a high voltage and to generate a corona discharge by using the static electricity of the object to be removed static electricity, can be used a lot in the manufacturing site because there is no regulation such as light irradiation.

In the self-discharge type, electrostatic induction occurs when a charged object is close to each other, and charges of opposite polarities with the charged object on the conductive object are collected. Corona discharge occurs when charges collect on a conductive object and exceed a certain amount, and the resultant air ions are attracted to the charged object as it is, and are combined with the charge of the charged object to become an electrical neutralization state. An antistatic is made by the same principle, and the antistatic bar 110 of the present invention is also made by this principle.

The first air nozzle 115 and the second air nozzle 116 may be formed in a cylindrical shape extending in the width direction of the seat 500. In this case, the cross section may be formed in a polygonal shape without being limited to a circle. In addition, a plurality of injection holes may be formed at the lower side of the first air nozzle 115 and the second air nozzle 116, and the gas may be injected to the outside. The gas is supplied through the air supply pipe 114 described above, and the sheet 500 is smoothly inserted by being injected onto the upper surface of the inserted sheet 500, and the sheet 500 is injected downward to be injected into the sheet 500. Guides downward movement). In this way, the sheet 500 is placed on the upper surface of the first sheet feed roll 210 and the second sheet feed roll 220 by the gas injected, it is possible to guide the insertion of the sheet 500.

The lower static elimination bar 120 will be described with reference to FIG. 7.
