Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a perspective view showing a partial cross-sectional view of the swap removal device in the filter container for explaining an embodiment according to the present invention, Figure 2 is an exploded perspective view showing an exploded main part of Figure 1, the cleaning spray tank (1) ), A cleaning tank 3 in which a cleaning solution is returned, and a swap removal device in a filter container is shown on one side of the cleaning tank 3.

The cleaning spray tank 1 has a plurality of spray heads 5 (illustrated with only one symbol for convenience) and a nozzle 7 for convenience, so that a strip passes through the spray solution therein. Only the reference numerals will be used to describe the components).

The spray head 5 and the nozzle 7 are connected to a pump 11 driven by a motor 9, and the pump 11 is connected to the cleaning tank 3 in a pipeline to spray the cleaning solution. It consists of structures that can be.

The cleaning tank 3 is filled with a cleaning solution therein.

In the swarf removal apparatus in the filter container, a moving shaft 21 is disposed inside the cleaning tank 3 so as to move in the axial direction as well as to rotate. The filter drum 23 is disposed on the outer circumference of the moving shaft. Are combined.

The filter drum 23 has an outer circumferential surface made of a mesh material so that the cleaning solution passes through the filter drum 23 to be stored in the cleaning tank 3, and the swarf can be filtered out. The filter drum 23 has a structure capable of linear movement and rotational movement in the axial direction also in accordance with the linear movement and rotational movement of the movement shaft (21). In addition, the filter drum 23 has an opening 23a formed in a length direction thereof. The opening 23a has a structure that can be selectively connected to the return line 25 is connected to the bottom of the cleaning spray tank (1). A rotation induction block 27 is disposed on an outer circumference of the moving shaft 21, and the rotation induction block 27 penetrates the moving shaft 21 and is fixedly coupled to an upper portion of the inner surface of the cleaning tank 3. The rotation induction block 27 is provided with an inclined groove 27a to have a rotational inclination so that the rotational movement can be made as the movement shaft 27 moves straight. And the moving shaft 27 is provided with a rotation guide bar (21a) protruding to correspond to the inclined groove (27a). Therefore, as the moving shaft 27 moves straight, the rotation guide bar 21a is inserted into the inclined groove 27a to move. Of course, the filter drum 23 may rotate in accordance with the rotation of the moving shaft 21. One side of the moving shaft 21 is connected to the rod of the cylinder 29 to move straight by hydraulic or pneumatic. Although not shown, the cylinder 29 has a structure in which a driving signal is transmitted and driven by a separate control device. An outer case 31 is coupled to one side of the cleaning tank 3.

The outer case 31 has a storage space formed therein and has a structure in which the filter drum 23 can be selectively inserted. In addition, the outer case case 31 is connected to the swab collection box 33 at its bottom through a conduit. Inside the outer case 31, there are arranged a plurality of spray heads 35, 37, which are described for the sake of convenience only and capable of injecting compressed air in the longitudinal direction. The spray heads 35 and 37 are provided with an air spray nozzle capable of injecting air, and are connected to a separate compressed air supply device (not shown). On one side of the outer head 31 is disposed a detection sensor 39 for detecting a state that the filter drum 23 is drawn into the outer case 31, the detection sensor 39 is a control unit (not shown) ) Is connected to a control valve (not shown) installed in a conduit for supplying compressed air.

Meanwhile, the filter drum 23 has a solution receiver 41 disposed at one side of the opening 23a, and a weight 43 is connected to the other end of the solution receiver 41. The bar connecting the solution receiver 41 and the weight 43 is hingedly coupled to the upper end of the cleaning tank, and the solution receiver 41 is always arranged upward by the weight. And one side of the bar connecting the solution receiver 41 and the weight 43 is attached to the limit switch 45 that can detect the state in which the solution receiver 41 is moved and transmitted to the control unit. When the swab is accumulated to some extent in the filter drum 23, the solution receiver 41 overflows the cleaning solution through the opening 23a, and when the solution receiver 41 is introduced into the solution receiver 41, the weight of the weight 41 is overcome and the bar moves to limit the switch. It has a structure that can operate (45).

The limit switch 45 is used to detect when the swarf needs to be removed and accumulated in the filter drum 23. The limit switch 45 is not limited to the structure of the present invention and may be freely changed according to design.

The swarf removal apparatus in the filter container thus formed has a cleaning solution in the cleaning tank 3 through the pipeline when the strip 11 is driven by the motor 9 when the strip moves into the cleaning spray tank 1. It enters into the spray head 5 in this cleaning spray tank 1, it is sprayed through the nozzle 7, and degreasing of a strip is performed. At this time, the cleaning oil is introduced into the opening 23a of the filter drum 23 through the return pipe 25 which includes a fine swab and is coupled to the bottom of the cleaning spray tank 1. Then, the filter drum 23 has an outer circumferential surface made of mesh ash, and the cleaning oil passes through the cleaning tank 3 to be reused. Repeating such a process causes the filter drum 23 to gather together and accumulate with a fine swap. When sufficient swarf is collected, the cleaning oil flows out toward the opening 23a of the filter drum 23. Then, the cleaning oil is collected in the solution tray 41, and the weight of the solution tray 41 becomes heavier than the weight 43, so that the limit switch 45 is brought into contact with each other. Then, the signal of the limit switch 45 is transmitted to the control unit, and the control unit drives the cylinder 29. As the cylinder 29 is driven, the rod of the cylinder 29 moves, and the moving shaft 21 connected with the rod also moves in the axial direction. At this time, the rotation guide bar 21a rotates while moving along the inclined groove 27a. When the moving shaft 21 moves while rotating, it is inserted into the outer head 31 and the opening 23a is downward. When the filter drum 23 moves to the outer case 31, the detection sensor 39 detects this and transmits the detected signal to the control unit. The control unit then controls the compressed air supply and control valve to draw compressed air into the spray head 37 in the outer case 31. Then, the compressed air is injected through the air jet nozzle, and the swarf in the filter drum 23 is removed and introduced into the swarf collection box 33 through the opening 23a. The control unit then returns to the original position by operating the cylinder after the swap removal operation is completed or a timer is driven for a predetermined time. Therefore, the swap in the filter drum 23 is automatically removed.

As such, the present invention provides an apparatus for automatically removing the swarf collected in the filter, reducing the disassembly and cleaning time of the filter box due to the clogging of the filter, completely filtering the cleaning solution, and introducing the cleaning solution into the cleaning tank. There is an effect of preventing clogging of the cleaning solution spray nozzle.
