Abstract

PURPOSE:To minimize the residual amt. of a coating material by building a coating material preparing and coating material circulating unit consisting of a coating material preparing device and coating material circulating device disposed with coating material feed pipings having expanding and contracting or lifting functions in a coating material can. CONSTITUTION:The valve of a driving source 12''e of a coating material feed piping lifting device for the sub-coating material can is held open during feeding of the coating material remaining in the sub-coating material can 15 in a coating position in the case of two pieces of the coating material cans to be used to the master coating material can 5. The coating material feed piping lifting device 12''b is driven via joints 12''d and 12''c for the driving power source for the coating material feed piping lifting device to lower the coating material feed piping 12a to its lower limit position at this time. A suction port exists in the lowest position as well and exists in the recessed part in the lower part on the inside surface of the sub-coating material can 15. The coating material remaining in the sub-coating material can 15 is thus mostly sent to the master coating material can 5 through coating material feed system joints 12c and 12d, a connecting piping 10 for the coating material cans and coating material receiving piping system joints 3'd and 3'c by driving the pump 12b through joints 12'd and 12'c for a pump driving source.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paint supply device for applying a paint contained in a paint can to a coating device.

[0002]

2. Description of the Related Art An outline of a conventional method is shown in FIG. Conventionally, the paint contained in a paint can is fed to the coating device 7 by immersing the paint feed pipe (for the parent paint can: pipe with pump 2b) 2 in the parent paint can 5 and feeding the paint, or A method is adopted in which one side of a pipe connected to a paint feed pipe (for a parent paint can: a pipe with a pump 2b) 2 is dipped to feed the paint. on the other hand,
For the paint return pipe from the coating device 7, see
The end of the paint return pipe (for parent paint can) 3 from the parent paint can 5
A method is employed in which the paint is returned from the coating device 7 by utilizing the dead weight of the paint by arranging or immersing the paint in the upper part. Further, as a supplement for consumption of the paint in the painting device 7, a child paint can 15 for paint replenishment is prepared, and a paint feed pipe (for child paint can: pump) is provided to the child paint can 15 and the parent paint can 5. 12b is used to send the paint from the child paint can 15 for paint replenishment to the parent paint can 5. A paint adjusting device (agitators 4a, 14a) is prepared as needed.

[0003]

The parent paint can 5 and the coating device 7 are provided with a paint feed pipe (for a parent paint can: a pipe with a pump 2b).
2 and paint return pipe (for parent paint can) 3 are connected, and when driving, pump drive source pipe and wiring (for parent paint can) 2'e
Is used to drive the pump 2b (for the parent paint can) to send the paint from the parent paint can 5 to the coating device 7 through the paint feed pipe (for the parent paint can: pipe with the pump 2b) 2 and to return the paint (the parent paint can). Excessive paint (such as overflow) is returned from the coating device 7 to the parent paint can 5 through the paint can 3).

Further, the paint is fed from the child paint can 15 for replenishing the paint to the parent paint can 5 by using a paint feed pipe (for child paint can: pipe with pump 12b) 12; It is difficult to send the paint between the lower opening of the pipe (for the child paint can) 12 and the inner bottom of the child paint can 15 to the parent paint can 5. On the other hand, if the distance between the lower opening of the paint feed pipe (for child paint can) 12 and the inner bottom of the child paint can 15 is made too small, the paint with high viscosity is consumed by the use of the painting device 7. Can't supply enough to replenish.

Therefore, during replenishment of consumption due to use of the paint in the painting apparatus 7, the paint feed pipe (for child paint can) 12
A necessary amount of space between the lower opening of the child paint can and the inner bottom of the child paint can 15, and when the remaining amount of paint in the child paint can 15 becomes low, the child paint can 15 is manually tilted or the paint is fed. The pipe (for child paint can) 12 is brought close to the inner bottom of the child paint can 15 to minimize the amount of paint that finally remains in the child paint can 15, which complicates the operation.

Therefore, according to the present invention, a gap between the paint feed pipe (for child paint can) 12 and the inner bottom portion of the child paint can 15 is maintained during the replenishment of the consumption of the paint in the painting device 7. When the required amount is secured and the amount of paint remaining in the child paint can 15 becomes small, the gap between the paint feed pipe (for child paint can) 12 and the inner bottom of the child paint can 15 is automatically minimized to prevent the paint residue. It is an object of the present invention to provide a paint supply device capable of minimizing the amount.

[0007]

The present invention advantageously solves the problems of the prior art, and as a result of the inventors' earnest efforts to achieve the above object, the paint coating device 7 While replenishing the consumption due to the use of, the necessary amount of space is secured between the paint feed pipe (for child paint can) 12 and the inner bottom of the child paint can 15, and the remaining amount of paint in the child paint can 15 is maintained. When it becomes low, the paint feed pipe (for child paint can) is automatically used 1
2 and the inner bottom of the child paint can 15 to a minimum,
It is possible to provide a paint supply device capable of minimizing the amount of paint remaining, and the gist of the invention is (1) in a paint supply device of a coating device using a paint can, A paint supply device characterized by incorporating a paint adjusting device and a paint circulating unit consisting of a paint circulating device having a paint feeding pipe having a stretching function or an elevating function into the paint can (2) Paint can The paint supply apparatus according to (1) is characterized in that a recess for sucking paint is provided at the bottom of the inner surface.
