Description

{Sheet rubber transfer}

The present invention relates to a sheet rubber feeding device, and more particularly to a sheet rubber feeding device in which a dipping liquid adhered to a festoon bar is washed by a washing liquid.

As shown in FIG. 1, a sheet rubber manufacturing apparatus generally includes a hermetic mixer 11 that mixes various types of rubber and chemicals to produce compounded rubber through a batch operation, a hermetic mixer 11, Having an extruder screw (13) for extruding the compounded rubber introduced through an extruder hopper (12) and a molding part (15) comprising a roller die or a sheet mill for molding compound rubber extruded at the outlet into sheet rubber, (16) for applying a releasing agent to the sheet rubber from the extruder (14), a drying / cooling section (17) for drying and cooling the sheet rubber via the incline conveyor, And a loading section 18 on which the sheet rubber having been dried and cooled is loaded.

In this drying / cooling unit 17, a filler type mold releasing agent (dipping solution) is accumulated in a festoon bar and is grown as a stone (icicle). These stones are broken when packer stacker is loaded, dust is generated, and the aesthetics of the apparatus are deteriorated. In addition, when the stalactite grows large, there is a problem of shortening the life of the chain for rotating the festoon bar.

3 is a side view of a cleaning part of a sheet rubber transfer device according to a preferred embodiment of the present invention (the first part is a sectional view).
4 is a front view of a cleaning part of a sheet rubber transfer device according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For reference, the same components as those of the conventional art will be described with reference to the above-described prior art, and a detailed description thereof will be omitted.

As shown in Figs. 2 to 4, the sheet rubber feeding device of the present embodiment includes a feeding portion for feeding the dipped sheet rubber through the festoon bar 110, a washing portion for washing the festoon bar 110 And the cleaning unit includes a liquid distributor 310 for spraying the cleaning liquid to the festoon bar 110.

The transfer part is a part for transferring the dipped sheet rubber, and may be a part of the batch off machine.

The transfer unit transfers the dipped sheet rubber through a plurality of festoon bars (110). The batch off machine has a cooling fan to cool the sheet rubber conveyed through the conveyance portion.

The plurality of festoon bars 110 are connected to each other and circulated through the chain 111. That is, the festoon bar 110 is provided in a rack drive type.

The chain (111) is moved by being caught by the sprockets (210, 220) arranged on the upper and lower sides, respectively. Two sprockets 210 and 220 are provided on the upper and lower portions, respectively, and are spaced apart from each other. At least one of the sprockets 210 and 220 is connected to a motor so that the festoon bar 110 is circulated.

The sheet rubber is conveyed by the festoon bar 110, and when it reaches the right side of the conveyance unit, the sheet rubber is conveyed upward and stacked.

After the sheet rubber is stacked, the festoon bar 110 is rotated clockwise to descend.

The sprockets 210 and 220 of the transfer unit, the motor, and the like are supported by the support frame.

The cleaning unit is disposed on the right side of the transfer unit to clean the festoon bar 110 after the sheet rubber is loaded.

Specifically, the cleaning portion is disposed between a portion where the sheet rubber is removed from the conveying portion and a sprocket 220 disposed at a right upper portion of the conveying portion.

The washing unit is disposed above the festoon bar 110.

The washing unit includes a liquid splitting unit 310 for spraying a cleaning liquid such as water to the festoon bar 110 and an air spraying unit 320 for spraying air to the festoon bar 110 after the liquid distributing unit 310. [ ).

The liquid distributor 310 is provided as a nozzle to spray the cleaning liquid at a high pressure.

The liquid distributor 310 is disposed at an upper portion of the festoon bar 110 to effectively remove the dipping liquid that is in contact with the sheet rubber.

The air spraying unit 320 can remove water or foreign matter remaining in the festoon bar 110.

The liquid splitting unit 310 and the air spraying unit 320 of the cleaning unit are detachably attached to the support frame of the conveyance unit through the clamp 330. Therefore, maintenance of the washing unit is easy, and the washing unit can be easily installed in the conventional transfer unit.

The clamp 330 includes a first portion 331 and a second portion 332 movably mounted relative to the first portion 331. The first portion 331 and the second portion 332, And a locking member for fixing the relative position of the locking member.

The first portion 331 includes a vertical bar portion vertically disposed on both sides and a connecting bar portion connecting the vertical bar portions on both sides. Accordingly, the first portion 331 is formed in the 'H' shape.

The vertical bar portion is formed with an insertion hole into which the second portion 332 is inserted at the upper portion and the lower portion, respectively.

And the liquid splitting part 310 or the air injection part 320 is installed in the connecting rod part.

The second portion 332 is provided at the upper portion and the lower portion of the first portion 331, respectively.

The second portion 332 includes a connecting portion for connecting the insertion bar portion fitted into the insertion hole of the vertical bar portion and the insertion bar portions on both sides. Accordingly, the second portion 332 is formed in the shape of a letter.

The insertion rod portion includes a vertical portion and a horizontal portion bent in the vertical portion. Accordingly, the clamp 330 is formed in a 'C' shape when viewed from the side.

The clamp 330 having such a shape prevents the cleaning liquid or the air from interfering with the clamp 330.

The connection portion is formed in a strip shape and may be formed of a rubber material. Therefore, it is possible to prevent the clamp 330 from slipping with respect to the support frame.

The locking member may be a through hole formed in the vertical bar portion and the insertion bar portion, and a pin inserted in the through hole.

A plurality of through holes may be formed in the insertion bar portion so that the vertical length of the clamp 330 can be adjusted.

Accordingly, the second portion 332 can be moved relative to the first portion 331 according to the thickness of the support frame, and then the relative position can be fixed through the locking member. Accordingly, the cleaning unit can be easily and quickly installed on the support frames of various types. It is also possible to adjust the angle of the liquid distributing unit 310 or the air injecting unit 320 through the clamp 330 so that not only the upper surface but also the side surface and the lower surface of the festoon bar 110 can be easily cleaned .

Hereinafter, the sheet rubber transfer device cleaning method of the present embodiment having the above-described configuration will be described.

The festoon bar 110, which is conveyed to cool the dipped sheet rubber, is washed after loading the sheet rubber. The present embodiment does not clean the festoon bar 110 during the process of circulating the festoon bar 110 so that the dipping liquid does not accumulate in the festoon bar 110.

First, the dipping liquid residing in the festoon bar 110 is cleaned by the high-pressure cleaning liquid through the liquid distributor 310 and removed.

Subsequently, air is sprayed to the festoon bar 110 through the air spraying unit 320 to remove remaining residue and water.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .
