[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paint removing apparatus.

More specifically, the present invention relates to a paint peeling device used to peel paint adhered to a metal cage or the like laid on the floor of a painting booth.

[0003]

2. Description of the Related Art FIG. 3 is a view for explaining a process of peeling a paint from a cage using a conventional paint peeling device or the like.

[0004] For example, a paint sticks to a bed placed on the floor of a painting booth as it is used. Here, if the paint adheres to the mat to a considerable extent, the slit portion of the mat is narrowed by the adhered paint, so that the exhaust efficiency and the like decrease. Therefore, it is necessary to peel off the paint when the paint has adhered to the bedboard to a considerable extent, but it is difficult to peel off the once solidified paint.

[0005] Therefore, conventionally, the sashimi is often subjected to a surface treatment so that the paint can be easily peeled off. That is, such a paddle is immersed in a stripping solution [for example, Polyceragard (trade name) manufactured by Kaken Kogyo Co., Ltd.] when not used, and then dried to form a peeling layer on the surface.

When the paint thus treated is used in a painting booth and the paint adheres to a considerable extent, the paint is peeled off using the paint peeling device 1.

Here, as shown in FIG. 3, the paint removing apparatus 1 comprises a main tank 2 containing a high temperature (80 to 98 ° C.) paint removing liquid Q1, and a paint removing liquid Q1 overflowing from the main tank 2. Tank 3 for accommodating the paint residue and the like, and a paint stripper Q in the overflow tank 3
It is composed of a pump 4 and the like for sucking 1 and circulating it in the main tank 2.

[0008] In order to remove the paint adhered to the sashimi W, the sashimi W is immersed in the paint remover Q1 in the main tank 2 and the paint adhered to the sashimi W is peeled off together with the release layer. On this occasion,
In the main tank 2, the paint stripper Q1 in the overflow tank 3 is circulated by the pump 4. However, the paint stripper Q1 in the main tank 2 is agitated by the circulated stripper Q1. It is done smoothly.

The paint W from which the paint has been removed in the main tank 2 is subjected to shower cleaning in a cleaning tank 5 using a cleaning liquid such as water. As a result, the paint is cleanly peeled off from the paddle W.

[0010] Thereafter, the drape W is immersed in a stripping solution Q2 (for example, the above-mentioned polyceragard) in the dip tank 7 and dried to prepare a stripped layer on the surface in order to prepare for reuse.

[0011]

However, in the above-mentioned conventional paint peeling device 1, the pump 4
Circulates a high temperature paint removal liquid Q1 at a temperature of at least 60 ° C., but in order to circulate such a high temperature liquid, a normal pump having a maximum operating temperature of about 60 to 70 ° C. cannot be used. It is necessary to use a heat-resistant pump (for example, a pump whose casing is made of stainless steel) that can withstand the pressure. Further, a motor (not shown) for driving the pump 4 needs to be provided with a cooling jacket for heat radiation.

Therefore, there is a disadvantage that the equipment becomes large and the cost increases.

SUMMARY OF THE INVENTION An object of the present invention is to provide a paint peeling device capable of reliably peeling paint while reducing the size and cost in view of the above circumstances.

[0014]

According to the present invention, there is provided a paint stripping apparatus having a main tank for storing a high-temperature paint stripper and an overflow tank for storing a paint stripper overflowing from the main tank. An ejector having a suction part and a discharge part is provided between the main tank and the overflow tank, the paint stripping liquid in the overflow tank can be sucked from the suction part by using a pressure fluid, and the discharge tank is used to discharge the paint removing liquid in the main tank. Characterized in that they are arranged so that they can be ejected.

[0015]

According to the present invention, for example, in order to remove paint from a mat to which the paint has adhered to a considerable extent, the paint is immersed in a paint stripper in the main tank and the paint is stripped from the surface of the mat.

At this time, the paint remover in the overflow tank is sucked from the suction part of the ejector by using the pressure fluid, and is discharged from the discharge part into the paint remover in the main tank. As a result, the paint removing liquid in the main tank is stirred, and the paint removing operation is smoothly performed.

Here, the ejector can withstand high temperatures similarly to the heat-resistant pump, but has a simple structure and is smaller and less expensive than the heat-resistant pump. In addition, since the ejector has no moving parts and does not easily break down, it is possible to reliably circulate the high-temperature liquid.

Therefore, it is possible to reliably remove the paint while reducing the size and cost.

[0019]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the paint peeling apparatus according to this embodiment comprises a main tank 11, an overflow tank 21, and a recovery tank 25.
And the ejector 31.

Here, the main tank 11 is heated to a high temperature (80 to 98).
C) can be stored. The main tank 11 is provided with a heating device 15 for heating the paint remover Q1.

The overflow tank 21 is provided in the main tank 11.
It is formed so as to be able to accommodate the paint stripping liquid Q1 and the like overflowing from the above.

The recovery tank 25 is formed so as to be able to further contain the paint stripping solution Q1 overflowing from the overflow tank 21 and the like.

Further, the ejector 31 has a suction part 32, a discharge part 33, and a pressure fluid passage part 34, and is disposed between the main tank 11 and the overflow tank 21.
More specifically, as shown in FIG.
The paint removing liquid Q1 in the overflow tank 21 from the suction part 32 using the pressure fluid flowing through the pressure fluid passage part 34.
Paint stripping liquid Q1 that can suck in and sucks in from suction section 32
Is provided so as to be able to be discharged from the discharge unit 33 into the paint removing liquid Q1 in the main tank 11. In the present embodiment, as the pressure fluid of the ejector 31, the paint removing liquid Q1 in the recovery tank 25 at a predetermined pressure using the pressure fluid supply device 35 is selected.

Next, the operation will be described.

In order to peel the paint from the paint W to which the paint has adhered to a considerable extent, the paint W is immersed in the paint removing liquid Q1 in the main tank 11 to peel the paint from the surface of the paint W.

At this time, the paint removing liquid Q1 in the overflow tank 21 is sucked from the suction portion 32 by the pressure fluid flowing through the pressure fluid passage portion 34 of the ejector 31, and the discharge portion 3
3 is discharged into the paint stripper Q1 in the main tank 11. As a result, the paint removing liquid Q1 in the main tank 11 is stirred, and the paint removing operation is performed smoothly.

Here, the ejector 31 withstands high temperatures like the heat-resistant pump, but has a simple structure and is smaller and less expensive than the heat-resistant pump. In addition, since the ejector 31 has no moving parts and does not easily break down, it is possible to reliably circulate the high-temperature liquid.

Therefore, the paint can be reliably removed while reducing the size and cost.

In the above embodiment, the paint stripper Q1 in the recovery tank 25 whose pressure has been increased is selected as the pressure fluid of the ejector 31. However, one of the low temperature paint strippers Q1 supplied to the main tank 11 is selected. A part which is diverted to a predetermined pressure may be used as a pressure fluid. Further, the pressure fluid supply device 35 may be constituted by a compressed air source.

[0031]

According to the present invention, an ejector having a suction part and a discharge part is provided between a main tank and an overflow tank.
The structure is arranged so that the paint remover in the overflow tank can be sucked from the suction part using the pressure fluid and can be discharged into the main tank from the discharge part, so that miniaturization and cost reduction are ensured. The paint can be peeled off.
