Description

  The present invention relates to a cleaning apparatus for cleaning an object to be processed before or after heat treatment.

  If a workpiece (hereinafter referred to as a workpiece) is heat-treated with dirt such as chips and oil attached to the surface, the heat treatment itself may not be performed, or unevenness may occur in the heat treatment, resulting in poor appearance. is there. For this reason, it is necessary to clean the workpiece.

  A conventional cleaning device is configured to spray a cleaning liquid from a spray nozzle onto a workpiece in a shower shape (see, for example, Patent Document 1). It is intended that the cleaning liquid is sprayed on the work and the dirt is washed away from the work by the force of spraying the cleaning liquid.

JP-A-4-332384 (paragraph 0014)

  However, in the conventional cleaning apparatus, the water flow of the cleaning liquid is linear, and there is a space between the lines in the water flow. No matter how close the spacing is, the spacing will occur as long as it is linear. For this reason, in the conventional cleaning apparatus, a portion where the cleaning liquid is not sprayed is generated on the workpiece, and the workpiece cannot be sufficiently cleaned.

  In particular, when the work is put in a state where it is stacked in a basket, even if a shower-like cleaning liquid is sprayed from above, the cleaning liquid does not easily hit the work in the central portion, so that dirt is not easily removed. For this reason, the washing | cleaning property of the workpiece | work of center part was inadequate. As described above, the conventional cleaning apparatus cannot sufficiently clean the workpiece.

  An object of the present invention is to provide a cleaning apparatus capable of improving the cleaning performance.

  The cleaning device of the present invention includes a supply pipe and a receptacle. The supply pipe is disposed in the horizontal direction and has a supply port along the longitudinal direction. The cleaning liquid supplied to the supply pipe flows out from the supply port. The receptacle contains a supply pipe inside and has an overflow part extending along the longitudinal direction of the supply pipe, and the cleaning liquid flowing out from the supply port is guided inside the overflow part to form a curtain from the overflow part. Configured to overflow.

  In this configuration, the overflow portion is configured to extend in the horizontal direction and along the longitudinal direction of the supply pipe. By continuing the supply of the cleaning liquid to the receiver, the cleaning liquid in the receiver overflows from the overflow portion extending in the longitudinal direction of the supply pipe, and flows into the work in a curtain shape along the overflow portion. For this reason, there is no interval like a shower in the water flow of the cleaning liquid, and the cleaning liquid is sufficiently poured on the workpiece. Further, since the amount of water is larger than when sprayed like a shower, even when the workpieces are stacked in multiple stages, the water flow reaches the workpiece in the center and the dirt is washed away.

  In the above-described configuration, the supply pipe is preferably a circular pipe, and the supply port is preferably provided below the central portion of the supply pipe in the height direction.

  In this configuration, the cleaning liquid flows out from the supply port downward in the horizontal direction, is guided upward, and overflows from the overflow portion. For this reason, the water flow of the cleaning liquid in the receptacle tends to be stable.

  Moreover, it is preferable that a supply pipe has the said several supply port arranged in parallel, and an overflow part is each provided in the both sides of a receiver.

  In this configuration, since the cleaning liquid flows out from both sides of the receptacle, the workpiece can be efficiently cleaned.

  Furthermore, it is preferable that the receptacle further includes an inclined plate extending obliquely downward on the outside from the overflow portion.

  In this configuration, the cleaning liquid overflowing from the overflow portion flows on the inclined plate, is discharged from the tip end portion of the inclined plate, and is applied to the workpiece. For this reason, the washing | cleaning liquid which overflowed from the receptacle is poured on a workpiece | work in the form of a curtain with small deviation | shift of the amount of water, without passing along the outer side surface of a receptacle.

  In addition, it is preferable to further include a first rectifying plate that is disposed so as to face the inclined plate outside the receiver and rectifies the cleaning liquid that has flowed out of the inclined plate.

  In this configuration, the cleaning liquid overflowing from the receptacle flows on the inclined plate, and jumps out obliquely downward immediately after being discharged from the tip of the inclined plate. By providing the first rectifying plate, the cleaning liquid flowing out of the inclined plate flows along the first rectifying plate and is rectified by the first rectifying plate. For this reason, the cleaning liquid can flow out in a desired direction depending on the shape of the first current plate. For example, by directing the lower end portion of the first rectifying plate directly below the receptacle, the cleaning liquid overflowing from the receptacle can be flowed out in a curtain shape directly below the receptacle. For this reason, a workpiece | work can be arrange | positioned directly under a receptacle, and the working space of a washing | cleaning apparatus can be made small.

  Furthermore, it can comprise so that a movement mechanism part which can move a receptacle to the direction orthogonal to the extension direction of an overflow part, and a drive source which moves a receptacle using a movement mechanism part can be provided.

  In this configuration, by installing the work below the overflow portion, the curtain-like cleaning liquid that vertically cuts the work is poured to the work while moving sideways. For this reason, the cleaning liquid can be poured evenly over the entire work installation area. Therefore, the cleaning liquid can be distributed to the details of all the workpieces.

  Moreover, it is preferable to further include a second rectifying plate that rectifies the cleaning liquid in the receptacle.

  In this configuration, the water flow of the cleaning liquid in the receptacle can be further stabilized. For this reason, the cleaning liquid that overflows from the overflow portion can be efficiently poured over the entire workpiece, and thus the moving distance of the receptacle can be shortened.

  According to the present invention, the washability can be improved.

Details of the cleaning head units 20 and 30 will be described later. As an example, the cleaning apparatus 10 is configured to clean a workpiece before heat treatment. For example, the workpieces are put in a state where they are stacked in a basket and are conveyed as a workpiece group 91.

  The conveyors 71 to 73 convey the workpiece group 91 so as to pass through the entrance door opening / closing device 81 and the exit door opening / closing device 82.

  The entrance door opening / closing device 81 is configured to open and close the conveyance path of the workpiece group 91 by the conveyors 71 to 73 by displacing the entrance door 811 up and down. Similarly, the exit door opening and closing device 82 is configured to open and close the conveyance path of the work group 91 by the conveyors 71 to 73 by displacing an exit door (not shown) up and down.

  In a state where the entrance door 811 and the exit door are arranged at the open position that opens the conveyance path of the workpiece group 91, the workpiece group 91 is in the cleaning region 92 between the entrance door opening / closing device 81 and the outlet door opening / closing device 82. , Conveyed by conveyors 71-73. In a state where the workpiece group 91 is arranged at a predetermined cleaning position, the conveyance of the workpiece group 91 is temporarily stopped, and in a state where the inlet door 811 and the outlet door are arranged at a closed position where the conveyance path of the workpiece group 91 is closed. Group 91 is washed. Thereby, the leakage of the cleaning liquid to the outside of the cleaning region 92 can be suppressed.

  After the work group 91 is cleaned, the cleaned work group 91 is transported out of the cleaning area 92 in a state where the entrance door 811 and the exit door are disposed at the open position, and the uncleaned work group 91 is transferred to the cleaning area 92. It is conveyed in.

  The cleaning head units 20 and 30 are disposed in the cleaning region 92. The cleaning head unit 20 and the cleaning head unit 30 are arranged side by side along the conveying direction of the work group 91 by the conveyors 71 to 73 (see the direction of the arrow 103). The cleaning head unit 30 is configured in the same manner as the cleaning head unit 20. As with the cleaning head unit 20, the cleaning device 10 includes equipment such as piping for supplying the cleaning liquid to the cleaning head unit 30.

  The cleaning tank 40 contains a cleaning liquid. The pump 50 supplies the cleaning liquid in the cleaning tank 40 to the cleaning head unit 20 through the first pipe 61, the second pipe 62, and the third pipe 63. As the second pipe 62, a flexible tube can be used.

  In the cleaning region 92, rack rails 93 and 94 are bridged in the direction along the transport direction 103.

  The cleaning head unit 20 has pinion gears 95 and 96. The pinion gears 95 and 96 mesh with the rack rails 93 and 94, respectively. The pinion gears 95 and 96 are rotated by the action of compressed air supplied from the air compressor 97. The cleaning head unit 20 is configured to move within a predetermined range along the rack rails 93 and 94 as the pinion gears 95 and 96 rotate. In this embodiment, the cleaning head unit 20 is configured to reciprocate within a predetermined range along the rack rails 93 and 94. The rack rails 93 and 94 and the pinion gears 95 and 96 constitute a moving mechanism unit that allows the receiver 22 to move in the direction along the conveyance direction 103, and the air compressor 97 moves the receiver 22 using the moving mechanism unit. A drive source is configured.

  Since the second pipe 62 has flexibility, the cleaning liquid is stably supplied to the cleaning head unit 20 even when the cleaning head unit 20 reciprocates in the direction along the conveyance direction 103.

  As shown in FIGS. 3 and 4, the cleaning head unit 20 includes a supply pipe 21, a receiver 22, first rectifying plates 23 and 24, and a second rectifying plate 25. In FIG. 4, the description of the second rectifying plate 25 is omitted.

  The supply pipe 21 is disposed in a horizontal direction so that its longitudinal direction is along a direction (see the direction of the arrow 101) perpendicular to the transport direction 103. The third pipe 63 communicates with the supply pipe 21, and the cleaning liquid in the cleaning tank 40 is supplied to the supply pipe 21 through the first pipe 61, the second pipe 62, and the third pipe 63. As an example, the third pipe 63 communicates with the central portion in the longitudinal direction of the supply pipe 12.

  The supply pipe 21 is a circular pipe and has slit-like supply ports 211 and 212. The supply ports 211 and 212 are formed long along the longitudinal direction of the supply pipe 21, and are arranged in parallel in the direction along the transport direction 103. The cleaning liquid supplied to the supply pipe 21 flows out of the supply ports 211 and 212 and is supplied into the receiver 22. The supply ports 211 and 212 are preferably provided below the central portion of the supply pipe 21 in the height direction so as to blow the cleaning liquid downward from the horizontal direction. The supply ports 211 and 212 are preferably provided in the entire area of the supply pipe 21 in the longitudinal direction.

  As indicated by an arrow 101, the receptacle 22 has a box shape that is long in the direction orthogonal to the conveyance direction 103 and opens upward only. In other words, the longitudinal direction of the receptacle 22 coincides with the longitudinal direction of the supply pipe 21. The receptacle 22 has overflow portions 221 and 222 extending linearly in the longitudinal direction. The overflow portions 221 and 222 are provided at both ends in the width direction (see the direction of the arrow 102) orthogonal to the longitudinal direction of the receiver 22, respectively. The receptacle 22 is configured to receive the cleaning liquid flowing out from the supply ports 211 and 212 to the overflow parts 221 and 222 so that the cleaning liquid overflows from the overflow parts 221 and 222. In addition, the longitudinal direction of the supply pipe 21 and the longitudinal direction and the width direction of the receiver 22 are all in the horizontal plane.

  The reciprocating direction of the cleaning heads 20 and 30 is the direction along the transport direction 103, in other words, the direction orthogonal to the extending direction of the overflow portions 221 and 222 (see the direction of the arrow 101).

  The overflow portions 221 and 222 extend in a range that vertically cuts the workpiece group 91 installed in the cleaning region 92.

  The supply pipe 21 is disposed at a height at which the supply ports 211 and 212 are below the overflow portions 221 and 222.

  The receptacle 22 further includes inclined plates 223 and 224 extending obliquely downward on the outside from the overflow portions 221 and 222.

  The first rectifying plates 23 and 24 are disposed outside the receptacle 22 so as to face the inclined plates 223 and 224, and are configured to rectify the cleaning liquid flowing out of the inclined plates 223 and 224. The first rectifying plate 23 and the first rectifying plate 24 are connected by a side plate 26.

  The first rectifying plate 23 includes a vertical portion 231 arranged in the vertical direction, and an inclined portion 232 that is provided at the lower end of the vertical portion 231 and is inclined toward the central portion in the width direction of the cleaning head portion 20. Similar to the first rectifying plate 23, the first rectifying plate 24 has a vertical portion 241 and an inclined portion 242.

  The second rectifying plate 25 rectifies the cleaning liquid in the receptacle 22. More specifically, the second rectifying plate 25 rectifies the cleaning liquid between the supply ports 211 and 212 and the overflow parts 221 and 222 in the flow direction of the cleaning liquid.

  In the cleaning device 10 configured as described above, the cleaning liquid accumulated in the receiver 22 is supplied from the overflow portions 221 and 222 extending in the longitudinal direction of the receiver 22 by continuing the supply of the cleaning liquid to the receiver 22. Overflows to the side. The cleaning liquid overflowing from the overflow portions 221 and 222 has a curtain shape. The cleaning liquid overflowing from the overflow portions 221 and 222 flows on the inclined plates 223 and 224.

  The cleaning liquid overflowing from the receptacle 22 flows on the inclined plates 223 and 224, and jumps out obliquely downward immediately after being discharged from the tip portions of the inclined plates 223 and 224. By providing the first rectifying plates 23, 24, the cleaning liquid that has flowed out of the inclined plates 223, 224 flows along the first rectifying plates 23, 24 and is rectified by the first rectifying plates 23, 24. For this reason, the cleaning liquid can flow out in a desired direction by the shape of the first rectifying plates 23 and 24.

  In this embodiment, the cleaning liquid flowing out from the inclined plates 223 and 224 is received by the vertical portion 231 and the vertical portion 241 and flows along the vertical portion 231 and the vertical portion 241. The first rectifying plate 23 has the inclined portion 232 at the lower end portion and the first rectifying plate 24 has the inclined portion 242 at the lower end portion, so that the cleaning liquid flowing along the vertical portion 231 and the vertical portion 241 is received by the receiver 22. It can flow out in the form of a curtain just underneath. For this reason, a workpiece | work group can be arrange | positioned directly under the receptacle 22, and the working space of a washing | cleaning apparatus can be made small.

  The pump 50 continues to supply the cleaning heads 20 and 30 with a cleaning liquid having an amount of water that allows the cleaning liquid to be poured to the workpiece group 91 to continue to have a curtain shape during cleaning.

  According to the cleaning device 10, the cleaning liquid can be poured into the workpiece group 91 in the form of a curtain. For this reason, there is no interval like a shower in the water flow of the cleaning liquid, and the cleaning liquid can be sufficiently poured onto the workpiece. Further, since the amount of water is larger than when sprayed like a shower, even when the workpieces are stacked in multiple stages, the water stream reaches the workpiece in the center, and the dirt can be washed away. Therefore, the cleaning property can be improved.

  Further, since the receptacle 22 includes the inclined plates 223 and 224, the cleaning liquid overflowing from the overflowing portions 221 and 222 flows on the inclined plates 223 and 224 and is discharged from the front end portions of the inclined plates 223 and 224. The work group 91 is applied. For this reason, since the cleaning liquid overflowing from the receptacle 22 does not travel along the outer side surface of the receptacle 22, it can be poured into the workpiece group 91 in a curtain shape with a small amount of water.

  Furthermore, since the cleaning liquid flows out from the overflow portions 221 and 222 provided on both sides of the receiver 22, the workpiece group 91 can be efficiently cleaned.

  Moreover, since the overflow parts 221 and 222 are provided in the area | region larger than the installation area | region of the workpiece | work group 91 in the washing | cleaning area | region 92 in the longitudinal direction of the receptacle 22, the overflow of the workpiece | work group 91 arrange | positioned in the washing | cleaning area | region 92 is carried out. The washing liquid can be poured over the whole.

  Further, the curtain-like cleaning liquid that vertically cuts the work group 91 is poured on the work group 91 while reciprocating horizontally. For this reason, the cleaning liquid can be poured evenly over the entire installation area of the workpiece group 91. Therefore, the cleaning liquid can be distributed to the details of all the workpieces.

  Further, at least the supply ports 211 and 212 of the supply pipe 21 are disposed in the receiver 22, and the cleaning liquid is supplied into the receiver 22 from the supply ports 211 and 212. For this reason, the water flow of the cleaning liquid in the receptacle 22 tends to be stable. Moreover, since the supply ports 211 and 212 are arranged in the direction along the overflow portions 221 and 222, the water flow of the cleaning liquid in the receptacle 22 is more stable. In addition, it is more preferable that the supply ports 211 and 212 are provided over the entire area of the overflow portions 221 and 222.

  Further, since the second rectifying plate 25 rectifies the cleaning liquid in the receiver 22, the water flow of the cleaning liquid in the receiver 22 can be further stabilized. For this reason, the cleaning liquid that overflows from the overflow portions 221 and 222 can be efficiently poured over the entire work group 91, and as a result, the moving distance of the receiver can be shortened.

  Note that the cleaning head units 20 and 30 may be configured to include only one of them.

  The supply ports 211 and 212 of the supply pipe 21 may be one or more than three.

  It is also possible to configure the overflow portions 221 and 222 provided on both sides of the receiver 22 as only one and the other as a dam higher than the overflow portion.

  Moreover, the overflow parts 221 and 222 are not limited to the shape extended linearly.

  The present invention can also be applied to a cleaning apparatus for cleaning a workpiece after heat treatment.

  The above description of the embodiment is to be considered in all respects as illustrative and not restrictive. The scope of the present invention is shown not by the above embodiments but by the claims. Furthermore, the scope of the present invention is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
