[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a floor cleaning device for a coating booth.

[0002]

[Prior Art]

 FIG. 2 is a diagram showing a schematic configuration of a conventional coating booth, and FIG. 3 is a diagram showing an example of a sludge-shaped block forming the floor surface of the coating booth.

In FIG. 2, reference numeral 1 denotes a coating chamber for coating a work W such as an automobile body. A paint spraying means (for example, a spray gun 8) is provided in the coating chamber 1. Further, above the coating chamber 1, an air supply chamber 2 equipped with an air supply fan is provided. Furthermore, below the coating chamber 1, there is provided a paint mist separation chamber 3 equipped with an exhaust fan and the like via a floor surface 5 through which ventilation is possible. The paint mist separating chamber 3 is provided with a venturi type paint mist removing device 4 for collecting the paint mist generated in the coating chamber 1 by gas-liquid contact.

A work transfer means for transferring the work W is provided in the coating booth. The work transfer means comprises a transfer rail 22 arranged on the floor surface 5 so as to extend in a direction perpendicular to the paper surface in FIG. 2, and a carriage 21A capable of traveling on the transfer rail 22 with the work W mounted thereon. It is configured. The carriage 21A is connected to the chain conveyor device 25 via the engaging means 26, and is run on the transport rail 22 by the conveyor device 25.

However, when the air supply fan and the exhaust fan are driven during spray coating of the work W using the spray gun 8 in the coating chamber 1, external air is supplied from the air supply chamber 2 to the coating chamber 1. The air in the coating chamber 1 is sent into the paint mist separating chamber 3 via the floor surface 5 in a state containing the paint mist. Then, the paint mist removing device 4 in the separation chamber 3 contacts and captures the paint mist with the atomized cleaning water Q.

Here, the floor surface 5 of the above-mentioned coating booth is constructed by laying a large number of slatted blocks 5a so that ventilation is possible.

The saw-like block 5a shown in FIG. 3 is formed in a rectangular (or square) shape with one side L of 450 mm to 500 mm, and has a large number of ventilation openings. This saw-like block 5a is firmly formed so as to support the work transfer means and the like, and to be held by a person when holding or inspecting the work. Therefore, it is generally configured to have a considerable weight (for example, 10 to 15 kg).

By the way, a paint mist or raw paint discharged at the time of switching the paint color adheres to and remains on each of the sludge-shaped blocks 5a constituting the floor surface 5. Therefore, when the coating work is performed in the coating chamber 1 for a certain period of time, the amount of the coating material remaining on the sludge-shaped blocks 5a increases, and the ventilation efficiency of the floor surface 5 decreases. If such a situation occurs, an excessive load will be applied to the exhaust fan and the like, and the efficiency of collecting the paint mist will also decrease.

Therefore, conventionally, the work of cleaning the sludge-shaped block 5a is regularly performed.

When performing such a cleaning operation, the operator peels off each of the sludge-shaped blocks 5a stuck to each other through the residual paint with a bar or the like, and then reaches the cleaning booth outside the coating booth. Transport and wash with chemicals to remove paints. Then, the washed and draining block 5a is transported and laid in the coating booth.

[0011]

[Problems to be solved by the device]

 By the way, in the cleaning work of the floor surface 5 (slat-shaped block 5a) of the coating booth as described above, it takes a lot of time and labor to remove, transport, and mount the heavy-weight sludge-shaped block 5a. Therefore, it will put an excessive burden on the worker.

In view of the above circumstances, an object of the present invention is to provide a floor surface cleaning apparatus for a coating booth that can easily and quickly clean the floor surface of the coating booth.

[0013]
