A front view showing a main part of a cleaning device when the lifting table is in the lowered position. The front view which shows the main part of the cleaning device when the lifting table is in the raised position.

Hereinafter, an embodiment of the cleaning device will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the cleaning device 11 has a substantially rectangular parallelepiped shape as a whole, and is installed so as to extend in the horizontal direction. In the present embodiment, the longitudinal direction of the cleaning device 11 will be the X direction, the vertical direction will be the Z direction, and the direction orthogonal to both the X direction and the Z direction will be described as the Y direction.

The cleaning device 11 includes a substantially rectangular parallelepiped frame 12 extending in the X direction. A panter arm type table lift 13 is arranged in the lower part of the frame 12. The table lift 13 is a circular plate-shaped elevating table 14, an elevating link mechanism 15 that engages with the elevating table 14, and a circular shape fixed to the other end side of a screw shaft 16 in which one end side of the elevating link mechanism 15 is screwed. It has a handle 17.

The screw shaft 16 extends in the X direction, and the handle 17 is located on the outside of the frame 12. Then, in the table lift 13, the elevating link mechanism 15 raises the elevating table 14 by rotating the handle 17 in one direction, and the elevating link mechanism 15 raises the elevating table 14 by rotating the handle 17 in the opposite direction to the one direction. The elevating table 14 is designed to be lowered.

As shown in FIGS. 2 and 3, a rectangular base plate 18 extending in the X direction is fixed to the upper surface of the elevating table 14. A pair of rails 19 extending in the X direction are provided on the upper surface of the base plate 18 at predetermined intervals in the Y direction. A rectangular parallelepiped cleaning tank 20 extending in the X direction is arranged on the pair of rails 19. In this case, a pair of wheels 21 are rotatably provided at one end and the other end in the X direction on the bottom surface of the cleaning tank 20, and each wheel 21 is mounted on the corresponding rail 19.

Two guide blocks 22 for guiding the cleaning tank 20 in the X direction are provided on both sides of the upper surface of the base plate 18 with the cleaning tank 20 sandwiched in the Y direction. Therefore, the cleaning tank 20 can reciprocate in the X direction while being guided by each guide block 22 by rolling along the rail 19 on the corresponding rail 19 of each wheel 21. The cleaning tank 20 can accommodate the entire cylindrical filter 23, and the cleaning liquid 24 for cleaning the filter 23 is stored inside. When the filter 23 filters the hydraulic oil of a machine such as an injection molding machine, for example, a washing oil or the like is used as the washing liquid 24.

The cleaning tank 20 includes a bottomed rectangular box-shaped case 25 having an open upper end and a bottomed rectangular box-shaped lid 26 that opens and closes the opening of the case 25. The lid 26 is rotatably provided about an axis extending in the X direction with respect to the case 25, and closes the opening position (position shown in FIG. 1) for opening the opening of the case 25 and the opening of the case 25. It is rotatable to and from the closed position (position shown in FIG. 2). The cleaning tank 20 of the present embodiment is made of a colorless and transparent synthetic resin material.

As shown in FIGS. 1 and 2, elongated holes 27 extending in the Z direction are formed so as to penetrate through the central portions of both side walls in the X direction in the cleaning tank 20. Each elongated hole 27 extends so as to straddle the case 25 and the lid body 26. A plurality of (three in this example) cleaning brushes 28 are provided at the central portion of the inner bottom surface of the case 25 so as to be evenly spaced in the X direction.

As shown in FIGS. 2 and 3, a moving force transmission mechanism 29 is provided at the end of the upper surface of the base plate 18 on the handle 17 side in the X direction. The moving force transmission mechanism 29 includes a pair of bearings 30, a shaft 31, a first oblique gear 32, a pair of discs 33, and a pair of links 34. The pair of bearings 30 are erected at both ends in the Y direction on the upper surface of the base plate 18. The shaft 31 extends in the Y direction, and both ends thereof are rotatably supported by a pair of bearings 30.

The first oblique tooth gear 32 is provided at the center of the shaft 31 in the Y direction so as to rotate integrally with the shaft 31. The pair of disks 33 are arranged outside the pair of bearings 30 in the Y direction, and their centers are fixed to both ends of the shaft 31. The pair of links 34 have a rod shape, and connect a position off-center on the outer surface of the pair of disks 33 in the Y direction and both side surfaces of the case 25 in the Y direction.

In this case, one end of each link 34 is rotatably connected to each disk 33 about an axis extending in the Y direction, and the other end is the handle 17 side of each side surface of the case 25 of the cleaning tank 20 in the X direction. It is rotatably connected to the lower end of the end portion about an axis extending in the Y direction. Therefore, when the shaft 31 is rotated, each disk 33 and each link 34 function as a crank mechanism, so that the cleaning tank 20 is reciprocated in the X direction.

As shown in FIGS. 1 and 2, a support shaft 35 extending in the X direction is inserted through the two elongated holes 27 of the cleaning tank 20. That is, the support shaft 35 extends so as to penetrate the washing tank 20 in the X direction, and is rotatably supported by the frame 12. A pair of circular support plates 36 capable of sandwiching the filter 23 are provided at an intermediate position of the support shaft 35 in the cleaning tank 20.

The pair of support plates 36 face each other in the X direction, and a filter insertion space 37 for inserting the filter 23 is formed between the pair of support plates 36. The support shaft 35 is divided into two in the X direction with the filter insertion space 37 in between, and each of the divided ends is connected to the central portion of the pair of support plates 36. In this case, the support shaft 35 and the pair of support plates 36 are integrally rotatably connected.

Of the two support shafts 35, the one located on the side opposite to the handle 17 side is the first support shaft 38, and the one located on the handle 17 side is the second support shaft 39. Of the pair of support plates 36, the one located on the side of the first support shaft 38 is the first support plate 40, and the one located on the side of the second support shaft 39 is the second support plate 41. The other end side of the first support shaft 38 whose one end side is connected to the first support plate 40 is rotatably connected to a clamp 42 provided on the frame 12.

The clamp 42 has a clamp lever 43. The clamp lever 43 is rotatable between a laid position (position shown in FIG. 2) and an upright position (position shown in FIG. 1). Then, when the clamp lever 43 was rotated from the laid position to the upright position, the first support shaft 38 and the first support plate 40 were slightly separated from the second support plate 41 in the X direction and laid down from the upright position. When rotated to the position, the first support shaft 38 and the first support plate 40 slightly approach the second support plate 41 in the X direction.

Therefore, when the clamp lever 43 is in the upright position, the filter 23 is inserted into the filter insertion space 37 in a position where the axis extends in the X direction, and the clamp lever 43 is rotated to the laid position. The filter 23 is clamped by the support plate 36. At this time, the axis of the support shaft 35 and the axis of the filter 23 coincide with each other, and the filter 23 is integrally rotatable by the pair of support plates 36. Then, when the clamp lever 43 is rotated from the laid position to the upright position, the holding state of the filter 23 by the pair of support plates 36 is released.

A second oblique gear 44 and a first spur gear 45 are provided adjacent to each other at an intermediate position of the second support shaft 39. The first spur gear 45 is arranged so that the distance from the second support plate 41 in the X direction is farther than that of the second oblique tooth gear 44. The mainspring motor 46 is arranged in a state of being fixed to the frame 12 at a position adjacent to the end of the second support shaft 39 on the side opposite to the side of the second support plate 41 in the Y direction.

A mainspring shaft 47 for winding a mainspring (not shown) is provided through the central portion of the mainspring motor 46. The mainspring shaft 47 extends in the X direction, and a second spur gear 48 is provided at the end on the cleaning tank 20 side. The second spur gear 48 has a larger outer diameter than the first spur gear 45 and meshes with the first spur gear 45. The tip of the lever 49 for rotating the mainspring shaft 47 is connected to the end of the mainspring shaft 47 on the side opposite to the second spur gear 48 side.

In this case, the lever 49 extends in a direction orthogonal to the mainspring shaft 47 and is connected to the mainspring shaft 47 via a one-way clutch (not shown). Therefore, when the lever 49 is reciprocally rotated, the mainspring shaft 47 is rotated only when it is rotated in one of the two rotation directions. When the mainspring shaft 47 is rotated, its rotational power is transmitted to the support shaft 35 via the second spur gear 48 and the first spur gear 45, and the support shaft 35 rotates.

When the support shaft 35 is rotated, the filter 23 housed in the cleaning tank 20 and sandwiched by the pair of support plates 36 rotates integrally with the support shaft 35. That is, the support shaft 35 supports the filter 23 housed in the cleaning tank 20 by a pair of support plates 36 that can rotate integrally with the filter 23 with the axis of the filter 23 as the center of rotation. In the present embodiment, the rotational force transmission mechanism that transmits the rotational force accompanying the rotational operation of the lever 49 to the support shaft 35 as the rotational force for rotating the support shaft 35 is the Zenmai shaft 47, the second spur gear 48, and the like. And the first spur gear 45.

The mainspring motor 46 exerts a force for rotating the support shaft 35 in the direction opposite to the rotation direction of the support shaft 35 when the mainspring shaft 47 is rotated by the rotation operation of the lever 49 to rotate the support shaft 35. accumulate. Further, the mainspring motor 46 includes a stopper (not shown) for preventing the accumulated force from being released, and a release lever 50 operated to release the stopper and release the accumulated force. ing.

As shown in FIGS. 2 and 4, the first oblique tooth gear 32 provided on the shaft 31 of the moving force transmission mechanism 29 is the second oblique tooth gear 44 provided on the support shaft 35 (second support shaft 39). It is located directly below. In the cleaning tank 20, each cleaning brush 28 is located directly below the filter 23 sandwiched between the pair of support plates 36.

Then, when the handle 17 of the table lift 13 is rotated in one direction to raise the elevating table 14, the cleaning tank 20 and the moving force transmission mechanism 29 are raised, and each cleaning brush 28 is sandwiched between the pair of support plates 36. The first oblique tooth gear 32 comes into contact with the peripheral surface of the filter 23 and meshes with the second oblique tooth gear 44 (the state shown in FIG. 4). Therefore, it can be said that each cleaning brush 28 is provided so as to be in contact with the peripheral surface of the filter 23 sandwiched between the pair of support plates 36 in the cleaning tank 20. The position of the elevating table 14 in this state (the state shown in FIG. 4) is the ascending position.

On the other hand, when the handle 17 of the table lift 13 is rotated in the opposite direction to lower the elevating table 14 from the state shown in FIG. 4, the cleaning tank 20 and the moving force transmission mechanism 29 are lowered, and each cleaning brush 28 supports a pair. The first oblique gear 32 is separated from the second oblique gear 44 (the state shown in FIG. 3) while being separated from the peripheral surface of the filter 23 sandwiched between the plates 36. The position of the elevating table 14 in this state (the state shown in FIG. 3) is the descending position.

The table lift 13 is in a state where each cleaning brush 28 comes into contact with the peripheral surface of the filter 23 sandwiched between the pair of support plates 36 by raising and lowering the elevating table 14 between the ascending position and the descending position. Each cleaning brush 28 switches between a state in which the cleaning brush 28 is sandwiched between the pair of support plates 36 and a state in which the filter 23 is separated from the peripheral surface. Therefore, in the present embodiment, the switching mechanism is configured by the table lift 13.

Next, the operation of the cleaning device 11 will be described.
When cleaning the filter 23 by the cleaning device 11, first, the handle 17 of the table lift 13 is rotated to move the elevating table 14 to the descending position. Subsequently, the lid 26 of the cleaning tank 20 is opened, and the cleaning liquid 24 is put into the case 25 until the liquid level reaches a predetermined height. Subsequently, the clamp lever 43 is rotated to an upright position, and the clamp lever 43 is rotated to a laid position with the dirty filter 23 inserted in the filter insertion space 37 in a position where the axis extends in the X direction. ..

Then, the filter 23 is sandwiched by the pair of support plates 36. At this time, the axis of the support shaft 35 and the axis of the filter 23 coincide with each other, and the filter 23 is integrally rotatable by the pair of support plates 36. Subsequently, the handle 17 of the table lift 13 is rotated to move the elevating table 14 to the ascending position. Then, as shown in FIG. 4, the cleaning tank 20 and the moving force transmission mechanism 29 are raised, and each cleaning brush 28 comes into contact with the peripheral surface of the filter 23 sandwiched between the pair of support plates 36, and the first oblique tooth gear. 32 meshes with the second oblique gear 44.

At this time, the lower end portion of the filter 23 including the contact portion with each cleaning brush 28 is immersed in the cleaning liquid 24. Subsequently, when the lever 49 is reciprocated, the mainspring shaft 47 is rotated. Then, the rotational power of the mainspring shaft 47 is transmitted to the support shaft 35 via the second spur gear 48 and the first spur gear 45, and the support shaft 35 rotates integrally with the filter 23 sandwiched by the pair of support plates 36.

As a result, the filter 23 is brushed in the rotational direction by each cleaning brush 28, and dirt on the surface of the filter 23 is scraped off by each cleaning brush 28. At this time, the mainspring motor 46 accumulates a force for rotating the support shaft 35 in the direction opposite to the rotation direction of the support shaft 35. Further, at this time, the rotational force of the support shaft 35 is transmitted to the shaft 31 of the moving force transmission mechanism 29 via the second oblique gear 44 and the first oblique gear 32, and the shaft 31 is rotated.

In the moving force transmission mechanism 29, when the shaft 31 is rotated, each disk 33 and each link 34 function as a crank mechanism, so that the cleaning tank 20 is in the axial direction of the filter 23 together with each cleaning brush 28. It is reciprocated in the X direction. That is, the moving force transmission mechanism 29 reciprocates each cleaning brush 28 in the axial direction of the filter 23 by reciprocating the rotational force accompanying the rotation operation of the lever 49 in a state where each cleaning brush 28 is in contact with the filter 23. Is transmitted to each cleaning brush 28 via the cleaning tank 20.

That is, the moving force transmission mechanism 29 applies the rotational force of the support shaft 35, which is rotated by the rotational force accompanying the rotational operation of the lever 49, in the axial direction of the filter 23 in a state where each cleaning brush 28 is in contact with the filter 23. The moving force for reciprocating each cleaning brush 28 is transmitted to each cleaning brush 28 via the cleaning tank 20. Therefore, since the filter 23 is brushed not only in the rotation direction but also in the axial direction by each cleaning brush 28, the dirt accumulated between the creases 52 extending in the axial direction of the filter medium 51 of the filter 23 is also brushed by each cleaning brush 28. Effectively scraped off.

Subsequently, after stopping the rotation operation of the lever 49, the handle 17 of the table lift 13 is rotated to move the elevating table 14 from the ascending position to the descending position. Then, as shown in FIG. 3, the cleaning tank 20 and the moving force transmission mechanism 29 are lowered, and the cleaning brush 28 and the cleaning liquid 24 are separated from the filter 23 sandwiched between the pair of support plates 36 and the first oblique tooth gear 32. Moves away from the second oblique gear 44.

Subsequently, the release lever 50 of the mainspring motor 46 is operated to release the force for rotating the support shaft 35 accumulated in the mainspring motor 46. Then, the mainspring shaft 47 is rotated at high speed by the released force. As a result, the rotational force of the mainspring shaft 47 is transmitted to the support shaft 35 via the second spur gear 48 and the first spur gear 45, and the support shaft 35 is fast together with the filter 23 sandwiched by the pair of support plates 36. It is rotated by.

Then, the cleaning liquid 24 adhering to the filter 23 is blown off by the centrifugal force when the filter 23 is rotated at high speed, so that the cleaning liquid 24 is efficiently removed from the filter 23. Subsequently, after opening the lid 26 of the cleaning tank 20, the clamp lever 43 is rotated from the laid position to the upright position while supporting the filter 23 by hand, so that the filter 23 is held by the pair of support plates 36. To release. After that, by removing the filter 23 from the cleaning tank 20, cleaning of the filter 23 by the cleaning device 11 is completed.

According to the embodiment described in detail above, the following effects are exhibited.
(1) The cleaning device 11 switches between a state in which the cleaning tank 20, the support shaft 35, the cleaning brush 28, and the cleaning brush 28 are in contact with the filter 23, and a state in which the cleaning brush 28 is separated from the filter 23. It is provided with a possible table lift 13 and a rotational force transmission mechanism that transmits the rotational force associated with the rotational operation of the lever 49 to the support shaft 35 as the rotational force for rotating the support shaft 35. According to this configuration, the support shaft 35 is formed by storing the cleaning liquid 24 in the cleaning tank 20 in which the entire filter 23 is housed and rotating the lever 49 with each cleaning brush 28 in contact with the filter 23. It rotates integrally with the filter 23. Therefore, each cleaning brush 28 can brush the filter 23 while immersing it in the cleaning liquid 24. Therefore, the tubular filter 23 can be washed as a whole.

(2) The cleaning device 11 accumulates a force for rotating the support shaft 35 in the direction opposite to the rotation direction of the support shaft 35 when the support shaft 35 is rotated by the rotation operation of the lever 49. To be equipped. According to this configuration, after cleaning the filter 23, the support shaft 35 is filtered by the released force by releasing the force accumulated in the mainspring motor 46 with the cleaning brush 28 and the cleaning liquid 24 separated from the filter 23. It can be rotated integrally with the 23. Therefore, the cleaning liquid 24 adhering to the filter 23 can be blown off by the centrifugal force accompanying the rotation of the filter 23, which can contribute to the efficient drying of the filter 23.

(3) The cleaning device 11 uses the cleaning brush 28 as a moving force for reciprocating the cleaning brush 28 in the axial direction of the filter 23 by reciprocating the rotational force accompanying the rotation operation of the lever 49 in a state where the cleaning brush 28 is in contact with the filter 23. The moving force transmission mechanism 29 for transmitting to 28 is provided. According to this configuration, the brushing effect of the cleaning brush 28 on the filter 23 can be enhanced, so that the filter 23 can be cleaned more effectively.

(4) Since the cleaning device 11 does not have any electrical configuration, it can be used without requiring a power source.
