Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to an upper lid of a cleaning tank, and more particularly to an improvement for preventing cleaning agent gas from being diffused to the outside of the cleaning tank.

(Background of the Invention) When the cleaning agent gas is diffused from the cleaning tank, environmental pollution such as ozone layer destruction due to CFCs progresses, and the working environment deteriorates due to irritating odor caused by hydrochloric acid or ammonia or stains on human body equipment. To do. In order to prevent these adverse effects and at the same time reduce the consumption of the cleaning agent, the cleaning tank has a structure in which the cleaning agent gas is not diffused as much as possible even when the cleaning object is taken in and out.

FIG. 2 is a structural explanatory view of a conventional washing tank with a bellows type upper lid,
The size of the cleaning material inlet / outlet port 19 is made equal to, for example, the maximum size of the opening sizes of the cleaning liquid tanks 16, 17, 17 arranged in the cleaning tank 15, and the outer periphery of the cleaning material inlet / outlet port 19 and the cleaning tank. A bellows 20 covers the periphery of the opening of 15. The cleaning product is taken in and out by moving the cleaning product inlet / outlet port 19 above the cleaning liquid tank in which the cleaning product is to be taken in and out of each of the cleaning liquid tanks, and the cleaning agent gas is diffused to the outside of the cleaning tank. By stopping the cleaning gas only from the cleaning material inlet / outlet port 19, the emission of the cleaning agent gas is suppressed. However, there is a gap between the peripheral edge of the opening of the cleaning tank 15 and the expanding and contracting sawtooth side edge of the bellows 20, and the bellows 20 always expands and contracts when the cleaning material inlet / outlet 19 is moved, so that the cleaning agent gas is discharged. Will be fueled. As a result, the cleaning agent gas is blown out from the gap by the bellows 20 and diffuses out of the cleaning tank 15 every time the cleaning material inlet / outlet port 19 is covered, even if the inlet / outlet port is moved. The applicant of the present invention is currently applying for a utility model registration regarding a device for a seat slide type cleaning tank upper lid that can remedy the above drawbacks.

FIG. 3 is a view showing an example of a sheet slide type cleaning tank upper lid in the application, in which the cleaning tank 30 has a rectangular opening, and the inside thereof has a long side direction (hereinafter referred to as a cleaning tank opening). Cleaning solution tanks 31, 32 and 3
3 are lined up.

A pulley drive unit 29 having a motor 29a is attached to the upper lid 21, and the pulley 27 and a pulley 28 coaxial therewith are rotated by the motor 29a.

Endless ropes 23 and 24 are laid between the pulley 27 and the pulley 25 and between the pulley 28 and the pulley 26, respectively. The pulleys 25 and 26 share a shaft. The ropes 23 and 24 are laid across the opening of the cleaning tank 30 in the lengthwise direction of the opening of the cleaning tank, and the linear portion of each rope is parallel to the opening surface of the cleaning tank 30.

A seat 22 is stretched between the ropes. Since the sheet 22 is made longer than the opening length of the cleaning tank in the rope erection direction, the entire opening of the cleaning tank 30 can be covered. Each opening of each cleaning liquid tank is rectangular, and each long side and both end edges of the sheet 22 are perpendicular to the rope erection direction.

When the pulleys 27 and 28 are rotated by the motor 29a in the above-described state, the sheet 22 slides along the opening surface of the cleaning tank 30, and the opening of the cleaning tank 30 moves through the opening.
1, 32, 33 are opened and covered in the direction in which they are arranged. For example, as shown in FIG. 3C, when the first edge 22a of the sheet 22 is located above the left end of the opening of the cleaning liquid tank 31, the opening of the cleaning tank 30 is fully opened. By rotating the pulley 27 counterclockwise in the drawing and moving the first end edge 22a sequentially from the left to the right in the drawing, it is possible to open only the upper part of the cleaning liquid tanks 32 and 33, and then the cleaning liquid tank 33.
Can be opened only above, and the entire opening of the cleaning tank 30 can be covered. Pulley 27
By rotating the second end edge 22b from the left side to the right side in the figure by rotating the same in the same direction as described above, only the upper part of the cleaning liquid tank 31 can be opened, and then only the upper parts of the cleaning liquid tanks 31 and 32 can be opened. Can be opened.

As described above, the sheet slide type cleaning tank upper lid currently applied for allows the cleaning tank opening to be opened from one end by a necessary width to allow the cleaning object to be taken in and out, and at this time, the sheet slides and moves. Therefore, the cleaning agent gas will not be agitated outside the cleaning tank and diffused.

(Problems to be Solved by the Invention) However, the above-mentioned pending sheet slide type cleaning tank upper lid has the following problems.

That is, since the gaps between the periphery of the cleaning tank opening and the sheet and between the sheet and the periphery of the cleaning tank upper lid opening are not closed, even when the sheet covers the entire cleaning tank opening, cleaning is performed. There is a problem that the agent gas leaks from each of the above-mentioned gaps and diffuses out of the cleaning tank through the opening of the cleaning tank upper lid.

An object of the present invention is to provide either a sealing member for closing a gap between a sheet covering the opening of the cleaning tank and a peripheral edge of the opening of the cleaning tank or a sealing member for closing a gap between the sheet and a peripheral edge of the opening of the cleaning tank upper lid. Provided is a sheet slide type cleaning tank upper lid seal capable of preventing the cleaning agent gas from leaking from the above gap and escaping to the outside of the cleaning tank by bringing one or both of them into close contact with the sheet. That is.

(Means for Solving the Problems) The sheet slide type cleaning tank upper lid seal of the present invention has the following means configuration in order to achieve the above object.

That is, the seal for a sheet slide type cleaning tank upper lid of the present invention is a cleaning tank side sealing member that presses a sheet covering the cleaning tank opening from the cleaning tank side to close the gap between the sheet and the periphery of the cleaning tank opening, or Has one or both of the upper lid-side sealing members for closing the gap between the sheet and the peripheral edge of the cleaning tank upper lid opening by pressure-contacting the sheet from the upper lid side, and if there is only one, the one Of the sealing member has a sheet pressing member on both sides of the sheet member on the opposite side of the sheet surface on which the sealing member is pressed, and in the case of having both, at least one sheet surface has a seal on the back side thereof. It is characterized in that it has a sheet pressing member that is pressed against both sides of the member.

(Operation) The operation of the seat slide type cleaning tank upper lid seal of the present invention having the above-mentioned means configuration will be described below.

The sheet covering the cleaning tank opening includes a cleaning tank-side sealing member that closes the gap between the sheet and the peripheral edge of the cleaning tank opening, or an upper lid-side sealing member that closes the gap between the sheet and the peripheral edge of the cleaning tank upper lid opening. Either one or both are pressed. In the case where only the cleaning tank side sealing member is pressed against the above sheet from the cleaning tank side, at the same time, the cleaning tank side sealing member is applied to the sheet surface opposite to the sheet surface on the side where the pressing is performed. The sheet pressing members are in pressure contact on both sides of.
Further, when only the upper lid side seal member is pressed against the above-mentioned sheet from the upper lid side, at the same time, both sides of the upper lid side seal member are attached to the sheet surface opposite to the sheet surface on the side where the pressure is applied. The sheet pressing member is in pressure contact with. Further, when both the above-mentioned sealing members are simultaneously pressed against the seat surface from both sides, the sheet pressing member is pressed against at least one seat surface on both sides of the seal member on the back surface side. As a result, the sheet is pushed in the direction opposite to the direction in which the sealing member on the cleaning tank side, the upper lid side, or both of them is pressed against the sealing member, so that the sheet surely comes into close contact with the above-mentioned sealing members.

Since the cleaning agent gas passes through the gap between the periphery of the opening of the cleaning tank and the sheet and then passes through the gap between the sheet and the periphery of the opening of the cleaning tank upper lid, it leaks out of the cleaning tank. Prevents the cleaning agent gas from escaping out of the cleaning tank when the sheet covers the entire opening of the cleaning tank by firmly adhering the sheet and the sheet to each other and surely stopping at least one of the leaks from the gaps. can do.

(Embodiment) An embodiment of the seat slide type cleaning tank upper lid seal of the present invention will be described below with reference to the drawings.

FIG. 1 is a configuration diagram of an embodiment of a seal for a sheet slide type cleaning tank upper lid of the present invention, (a) is a top view and (b) is its A
-A sectional view taken along line A. In the figure, the cleaning tank opening 10
A seal member 6 and a sheet pressing member 5 and 7 are provided around a. Each of these members presses against the sheet 2 when the sheet 2 covers the entire cleaning tank opening 10a. There is. The seal member 6 is pressed against the sheet surface of the sheet 2 that faces the cleaning tank opening 10a, and closes the gap between the sheet 2 and the peripheral edge of the cleaning tank opening 10a. The sheet pressing members 5 and 7 are in pressure contact with the sheet surface facing the upper lid opening 1a of the sheet 2 on both sides of the seal member 6. As a result, the seal member 6 is surely brought into close contact with the sheet 2, so that the leakage of the cleaning agent gas from the gap between the peripheral edge of the cleaning tank opening 10a and the sheet 2 can be stopped without fail, and the cleaning agent gas is removed from the cleaning tank. Can be prevented.

In this embodiment, the seal member 6 is provided on the cleaning tank side of the sheet 2 and the sheet pressing members 5 and 7 are provided on the upper lid side. However, the sealing member is provided on the upper lid side and the sheet pressing member is provided on the cleaning tank side. Also in this case, the same operation as in this embodiment can be performed. Further, the sheet pressing member only needs to push the sheet, and it is not necessary to close the gap between the sheet and the peripheral edge of the cleaning tank opening or the upper lid opening. However, in the present embodiment, the sheet pressing member 5 and 7 are the same. Since the gap between the peripheral edge of the upper lid opening 1a and the sheet 2 is closed, the cleaning agent gas is more reliably discharged to the outside of the cleaning tank as compared with the case where the leakage of the cleaning agent gas is stopped only by the seal member 6. It can prevent the radiation.

(Effects of the Invention) As described above, the seal for the sheet slide type cleaning tank upper lid of the present invention is the sealing member for closing the gap between the sheet covering the cleaning tank opening and the periphery of the cleaning tank opening or the cleaning with the sheet. One or both of the sealing members that close the gap between the tank lid opening and the peripheral edge are pressed against the above-mentioned sheet, and when only one of them is pressed, the opposite side of the sheet surface of the sealing member is pressed. The sheet surface of the seal member is pushed by both sides of the seal member, and when both are pressed, at least one of the sheet surfaces is pushed by both sides of the seal member on the back surface side of the seal member. Since it is possible to reliably seal at least one of the above-mentioned gaps in which the leakage path of the cleaning agent gas is formed in series, the leakage of the cleaning agent gas causes the cleaning agent gas from leaking out of the cleaning tank. It has the advantage that it can be prevented from radiating to
