DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning brush replenishing device for sequentially supplying a large number of cleaning brushes to a robot or a cleaning device for cleaning a thin tube of a condenser or a heat exchanger.

[0002]

2. Description of the Related Art Conventionally, when cleaning thin tubes of a condenser or a heat exchanger, a cleaning brush is inserted from one end of each thin tube and compressed air or pressure water is supplied from behind the cleaning brush to clean the thin tubes. To the other end to clean the thin tube. Such a cleaning brush is usually carried in a lot from a manhole into a water chamber to which one end of the thin tube tube is connected and opened via a container. However, since the water chamber is carried through a small manhole, it is inconvenient and requires a great deal of labor to carry a large number of cleaning brushes. It is desirable to sequentially pump with water.

In this case, as shown in FIG. 10, a conveyor belt 63 is provided to connect guide tubes 62 into which cleaning brushes 61 are inserted.
A replenishing device that sequentially moves the cleaning brush 61 to the carry-in port 4 and feeds the cleaning brush 61 is conceivable. As shown in FIG. 11, a replenishing device that sequentially feeds the cleaning brushes 71 from the stock box 72 in which the cleaning brushes 71 are stacked and stored to the carry-in port of the transport tube 74 via the inclined guide wall 73 by gravity is conceivable.

[0004]

However, although the former is extremely reliable, it is necessary to facilitate the guide cylinder 62 in accordance with the size of the cleaning brush 61 (the size of the thin tube). There is a problem that the system is complicated and the cost is high if the winding is included. In the latter case, although the device cost is low, there is a problem that the cleaning brush 71 is clogged and cheap and the reliability is low.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a cleaning brush replenishing apparatus which solves the above-mentioned problems, has a simple structure, has high reliability, and can be provided at low cost.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a cleaning device for cleaning a brush cleaning brush with a pressurized fluid. A cleaning brush replenishing device for supplying a cleaning brush to be supplied via a supply tube, wherein a cassette case having a plurality of brush receiving holes for removably receiving the cleaning brush is formed from a front surface to a rear surface, and the cassette case is replaceable. And a movable body disposed on the mount and movable by a moving device along the front and back surfaces of the cassette case. The movable body can be moved to a position facing each brush accommodating hole of the cassette case. And a fluid supply nozzle and a brush supply nozzle which are connected to the brush housing hole of the cassette case. It is obtained by connecting the tubes.

According to the above arrangement, the fluid supply nozzle and the brush supply nozzle are sequentially connected to the plurality of brush accommodating holes formed in the brush cassette by moving the movable body, and the cleaning brush for the brush accommodating holes is brushed by the pressurized fluid. Since it is sent to the supply tube, it can be provided with a simple configuration, high reliability and low cost. In addition, by using the brush cassette, a large number of cleaning brushes can be easily handled and the volumetric efficiency is high. By replacing the brush cassette, a large number of cleaning brushes can be easily and reliably supplied.

According to a second aspect of the present invention, in the above-described structure, the movable member is formed at the front and rear surfaces of the cassette case so as to face each other, and at the outer periphery of the fluid supply nozzle and the brush supply nozzle. A nozzle retracting device having a cylinder chamber for retracting the fluid supply nozzle and the brush supply nozzle toward the cassette case is provided between the piston cylinder and the piston cylinder.

[0009] According to the above configuration, since the nozzle retracting device provided on the movable body is formed by forming the piston chamber on the outer periphery of the nozzle, it can be made compact and lightweight. The operation of the movable body can be facilitated.
