Description

washing machine

The present invention relates to a washing machine, and as an object to be cleaned (hereinafter, also referred to as a "work"), for example, a vehicle part formed of a metal material, a plastic material, a ceramic material, and machined or molded. Related to a washing machine that cleans various parts such as mechanical parts and precision parts. Further, the present invention is particularly suitable for performing efficient cleaning with no unwashed residue on a work having a complicated uneven shape including a step portion, a groove portion, a hole portion, a notch portion, a gap and the like. Regarding the washing machine.

In general, for example, even in machining, chips and chips are generated during cutting, and if the generated chips and chips are left as they are, they will adhere to the work and cause defective products. .. Further, since cutting oil is usually used in the cutting process, chips and chips are likely to adhere to the work due to the cutting oil. Therefore, after cutting, it is necessary to wash the work to remove chips and chips from the work together with cutting oil.
Therefore, conventionally, a cleaning liquid injection nozzle for injecting a cleaning liquid and an air injection nozzle for injecting air are arranged around a work (object to be cleaned), and the cleaning liquid and air are injected toward the work. A so-called injection type work cleaning device having the above structure is known.

However, in this injection type work cleaning device, cutting oil or cutting is applied to a work having a complicated uneven shape including a step portion, a groove portion, a hole portion, a notch portion, a gap, and other portions whose shape changes. Foreign substances such as powder could not be sufficiently removed, and there were problems such as uneven cleaning. In this case, in particular, there is a possibility that the cleaning liquid does not sufficiently enter the boundary portion where the shape of the uneven shape changes and the peripheral portion thereof, and as a result, the cleaning liquid is sufficiently removed by cleaning every corner of the work. It was difficult to do.

Further, as a conventional technique which is the background of the present invention, a work cleaning device has been proposed that removes foreign matter adhering to a work having a complicated uneven shape (see, for example, Patent Document 1). As shown in FIG. 1 of Patent Document 1, the work cleaning device 10 rotatably supports the blade 30 as a work, and the cleaning liquid is directed toward the work support 11 and the blade 30 supported by the work support 11. It is provided with a nozzle 20 that discharges and applies a rotational force to the blade 30 by the discharge pressure of the cleaning liquid, and is characterized in that the blade 30 is cleaned by utilizing the centrifugal force generated by the rotation of the blade 30.

That is, in this work cleaning device 10, as shown in FIG. 3A of Patent Document 1, at least one nozzle 20 is arranged below the blade 30 supported by the work support base 11, and is exposed from the core 33. The cleaning liquid 21 is discharged toward the surface 34a of the blade portion 34. The point where the cleaning liquid 21 hits the surface 34a of the blade portion 34 is the contact point P of the cleaning liquid 21.
As a result, the blade 30 is given a rotational force by the discharge pressure of the cleaning liquid 21, and rotates around the shaft portion 13 of the work support 11 in the direction indicated by the arrow in FIG. 3A. As the blade 30 rotates, the cleaning liquid 21 hits the blades 34 of the blades 30 arranged in the circumferential direction. Further, as shown in FIG. 3D, a part of the cleaning liquid 21 that hits the front surface 34a of the blade portion 34 also scatters on the back surface 34b of the adjacent blade portion 34.
Further, as shown in FIG. 3B, the cleaning liquid 21 that hits the surface 34a of the blade portion 34 directs the surface 34a of the blade portion 34 from the radial outer side (contact point P) to the radial inner side by the discharge pressure. The foreign matter adhering to the surface 34a is removed by the physical cleaning power of the cleaning liquid 21 and the chemical cleaning power of the cleaning liquid 21. As a result, the first cleaning is performed.

Further, since the blade 30 is rotating, a centrifugal force acts on the cleaning liquid 21 flowing inward in the radial direction on the surface 34a of the blade portion 34. Therefore, the cleaning liquid 21 flowing inward in the radial direction eventually reverses its flow direction and flows on the surface 34a of the blade portion 34 from the inner diameter in the radial direction to the outer diameter in the radial direction as shown in FIG. 3C. Removes foreign matter adhering to the surface 34a. This causes a second wash.
Further, as shown in FIG. 3D, the cleaning liquid 21 that hits the front surface 34a of the blade portion 34 and is scattered on the back surface 34b of the adjacent blade portion 34 causes the back surface 34b of the blade portion 34 to be radially inside by the action of centrifugal force. It flows outward in the radial direction from the surface, and removes foreign matter adhering to the back surface 34b for cleaning.

According to the conventional work cleaning device 10, the discharged cleaning liquid 21 flows inward in the radial direction from the contact point P with the blade 30, and then flows again at the contact point P due to the centrifugal force generated by the rotation of the blade 30. After the first cleaning is performed by the pressure of the cleaning liquid 21, the second cleaning is performed by the cleaning liquid 21 flowing by centrifugal force, and the blade 30 can be cleaned twice, and the foreign matter adhering to the blade 30 can be efficiently removed. It is mentioned that since it can be removed well, the cleaning power per unit time can be improved and the amount of the cleaning liquid 21 used can be reduced.

However, this conventional work cleaning device 10 is not suitable for incorporating the work cleaning device 10 into the automation of a production line in order to improve productivity, stabilize product quality, reduce labor costs, and the like. It was a thing. That is, when a large number of workpieces are continuously washed and the washed workpieces are handled by, for example, an industrial robot and moved to the next process, the rotation of the cleaned workpieces is stopped and then the workpieces are moved to the next process. Although it is necessary, the conventional work cleaning device 10 does not have a braking mechanism for forcibly stopping the rotation of the work after cleaning, but naturally stops the work, so that the production efficiency per unit time is low. Become.
In some cases, the worker forcibly stops the rotation of the work by hand, but in this case, there is a risk of injury to the worker, which is problematic in terms of safety.

On the other hand, as a conventional technique behind the present invention, as a safety measure when the opening / closing lid is opened, a cleaning device for machine parts incorporating a forced stopping means for forcibly stopping the rotation of the work is incorporated in the cleaning booth. Has been proposed (see, for example, Patent Document 2). In this work cleaning device 10, as shown in FIGS. 4 and 6 of Patent Document 2, a wire 50 having one end fixed to the inner surface of the cleaning booth 1 is placed on a rotating plate 11 and a base plate 9 with a roller 51. After hanging around the wire, the tip of the tip is taken out of the cleaning booth 1 and fixed to a lock lever 52 attached to the outer surface of the cleaning booth 1.
The lower end of the lock lever 52 is pivotally supported on the outer surface of the cleaning booth 1, and can be pulled forward from the upright state shown in FIGS. 4 and 6 of Patent Document 2 and rotated downward (Patent Document 2). The state of FIG. 1), the tip of the wire 50 fixed to the lock lever 52 is pulled and becomes tense during this downward rotation. Thus, the rotating plate 11 is pressed by the wire 50 in this tense state, and its rotation is forcibly stopped.

Further, in this conventional cleaning device for mechanical parts, as another forced stopping means, an air nozzle or a liquid nozzle that exerts a force in the reverse direction on the rotating element of the work receiver that rotates in the normal direction, and an air nozzle or a liquid nozzle that are installed on the inner surface of the cleaning nozzle are installed. Proposed ones include a leaf spring that allows only the forward rotation of the rotating element of the work receiver and prevents the reverse rotation. As shown in FIGS. 5A and 5B of Patent Document 2, the forced stop means installs a work braking air nozzle 48 (or a cleaning liquid nozzle), and uses the work braking air nozzle 48 in the cleaning booth 1. It is driven based on the operation accompanying the opening operation of the opening / closing lid 4 of the switch (sensor) (not shown) installed on the upper part of the above, so that, for example, the impeller 25 in the normal rotation state is given a braking force in the reverse direction for a short time. ing.

Japanese Unexamined Patent Publication No. 2014-188411 (see pages 5-7, FIGS. 1 to 3, etc.) Japanese Unexamined Patent Publication No. 2008-253960 (see pages 4-5, FIG. 3, FIG. 4, FIG. 5, FIG. 6, etc.)

However, in the conventional cleaning device for mechanical parts described above, the opening / closing lid is manually opened each time the work after cleaning is moved to the next process in either the forced stopping means or another forced stopping means. Since it is necessary to take out the work from the cleaning booth, even if this conventional cleaning device for mechanical parts is incorporated into the automation of the production line, it is still unsuitable for increasing the productivity.
Further, in another forced stop means of the conventional cleaning device for mechanical parts, a work braking air nozzle (or a cleaning liquid nozzle) is used to apply a force in the reverse direction to the rotating element of the work receiver that rotates in the normal direction. Therefore, if the work is not sufficiently dried after cleaning the nozzle, or if the work is rotated in the reverse direction, the cleaning liquid that adheres to the columns, base plate, fixed shaft, rotating plate, adapter work receiver, etc. in the cleaning booth. There was a risk that the cleaning liquid would adhere to the dried work. Further, when the work is stopped by this forced stop means, the stop position of the work is likely to change each time, and it is extremely difficult to keep the stop position constant.
Further, one conventional work cleaning device has, in particular, a through hole of a blade, a step portion provided around a shell and a core, or a shadow portion which overlaps with another blade portion or a core and becomes a shadow in the blade portion. Foreign matter adhering to the joint portion that is the boundary between the blade and the shell and the joint that is the boundary between the blade and the core cannot be sufficiently removed, so-called uneven cleaning. Was likely to occur. Further, in the other conventional cleaning device for mechanical parts, the air nozzle 13 and the cleaning liquid nozzle 14 are paired or a plurality of pairs on the inner surface of the cleaning booth 1 so that the tips thereof face the work 70 set in the work receiver. Since the opening / closing lid 4 is also provided with an air nozzle 13 and a cleaning liquid nozzle 14 for injecting air and cleaning liquid from above onto the work 70 (see FIG. 3 of Patent Document 2), the lower surface of the work and the lower surface of the work and the cleaning liquid nozzle 14 are installed. Foreign matter adhering to the lower side of the inner surface could not be sufficiently removed, and there was a risk of uneven cleaning.

Therefore, a main object of the present invention is to provide a washing machine capable of stopping a work after washing at a fixed stop position and suitable for incorporation into the automation of a production line.

The mounting piece 86a is rotatably mounted on the long side portion 84b. Further, the mounting piece 86b of the positioning support column 86 is fitted into a mounting hole (not shown) provided in the base plate 80, and a mounting screw (not shown) is screwed into the screw hole of the mounting piece 86b. As a result, the mounting piece 86b is mounted on the base plate 80.
On the other hand, the short side portion 84a of the positioning claw holding piece 84 has a mounting hole (not shown) on the other end side in the longitudinal direction thereof, as described above, and the positioning claw operating means 88 is provided in the mounting hole. A first connector 92A for connecting to is connected.

Therefore, an example of the mounting structure of the positioning claw operating means 88 used in the positioning mechanism 50 according to the embodiment of the present invention will be described below.
For example, an air cylinder (hereinafter, also referred to as an air cylinder 88) is used as the positioning claw operating means 88. The air cylinder 88 has a piston rod 88A that can reciprocate on one side in the length direction (axial direction). The air cylinder 88 has a built-in sensor switch (not shown) that detects the reciprocating movement of the piston rod 88A. In this case, the piston rod 88A is extended, the sensor switch is turned on at the position where the forward / extension (forward) of the piston rod 88A is completed, and the sensor is at the position where the piston rod 88A is completed at the position where the return / shorten (reverse) is completed. The reciprocating movement of the piston rod 88A is detected so that the switch is turned off.

Further, the tip end portion of the piston rod 88A is rotatably connected to the short side portion 84a of the positioning claw holding piece 84 via the first connecting tool 92A. Further, the other side of the air cylinder 88 in the length direction (axial direction) is connected to the positioning actuating means fixing tool 90 via the second connecting tool 92B, and the operating means fixing tool 90 is fixed to the base plate 80.

In this case, the actuating means fixture 90 includes, for example, a rectangular vertical piece 90a, as shown in FIGS. 10 and 11, with mounting pieces 90b and 90c at the upper and lower ends of the vertical piece 90a, respectively. It is arranged. The mounting pieces 90b and 90c are provided so as to extend vertically from the upper end and the lower end of the vertical piece 90a toward the longitudinal direction of the base plate 80, respectively.

For example, a knuckle joint is used for the first connecting tool 92A and the second connecting tool 92B, respectively. One connector 92A is rotatably connected to the short side portion 84a of the positioning claw holding piece 84 by a knuckle pin 94. Further, the other connecting tool 92B is rotatably connected to the upper mounting piece 90c of the positioning operating means fixing tool 90 by a knuckle pin 95. Further, as shown in FIGS. 10 and 11, the piston rod 88A is covered and covered with, for example, a cylinder cover 96 having an inverted U-shaped cross section.

Further, in the positioning mechanism 50, a claw stopper 98 of the positioning claw 82 is arranged in the vicinity of the positioning support column 86a. As shown in FIGS. 10 and 12, the claw stopper 98 is formed of, for example, an adjust bolt having a threaded surface on the peripheral surface of the shaft portion thereof. As shown in FIG. 12B, for example, when the positioning claw actuating means 88 is activated and the positioning claw holding piece 84 is rotated in the clockwise direction in a plan view with the mounting piece 86a of the positioning column 86 as a pivot axis. In addition, it has a stopper function to prevent it from rotating clockwise more than necessary.

The claw stopper 98 is attached to the base plate 80 by, for example, an L-shaped claw stopper attachment 100. As shown in FIGS. 10, 11 and 12, for example, the claw stopper attachment 100 includes a long side portion 100a and a short side portion 100b, and is formed in an L shape. The long side portion 100a has a screw hole (not shown) through which the claw stopper 98 can be screwed, and the short side portion 100b is spaced apart in the longitudinal direction thereof, for example, two screw holes (not shown). have. In this case, the claw stopper attachment 100 is attached to the base plate 80 by screwing the attachment screw 99 into the screw hole of the short side portion 100 thereof. Further, a claw stopper 98 is attached to the long side portion 100a of the claw stopper attachment 100 so as to be reciprocating in the axial direction in the screw hole.

When the positioning mechanism 50 is not operating, as shown in FIGS. 13 and 14, even if the positioning blade portion 60 of one of the plurality of blade portions 58 and the positioning claw 82 are at opposite positions, the positioning blade The arcuate portion R at the tip of the positioning claw 82 does not come into contact with the top surface 61B of the portion 60. Further, even if one of the blade portions 58 and the positioning claw 82 are at positions facing each other, as shown in FIGS. 15 and 16, the positioning claw 82 is placed on the top surface 58B of the blade portion 58. The arcuate portion R at the tip of the tip is not in contact with the arcuate portion R.

On the other hand, by operating the air cylinder 88 (positioning claw operating means) of the positioning mechanism 50 at the position where the rotation of the jig 52 is stopped by the brake mechanism 10, for example, as shown in FIGS. When the positioning claw 82 is inserted into the circumferential space SP (particularly, see FIG. 7, for example) by the air cylinder 88, as shown in FIGS. 19 and 20, for example, the arcuate portion R at the tip of the positioning claw 82 is formed. When the positioning blade portion 60 is in a position where it does not abut on the top surface 61B, the accelerator air blow nozzle 313 (see, for example, FIGS. 21, 35 and 36) as a jig rotation imparting blow nozzle is operated. The jig 52 can be rotated clockwise or counterclockwise to bring the positioning claw 82 into contact with one side 61C or the other side 61D of the positioning blade 60, for example as shown in FIGS. 17 and 18. ..
In this case, the rotation of the jig 52 is stopped at the position where the positioning claw 82 abuts on the side surface 61C or the side surface 61D of the positioning blade portion 60. Thereby, the work W can be positioned at a predetermined position.

The air upper supply pipe 190 is movably arranged so as to be able to approach and separate from the work W in particular. As shown in FIGS. 35 and 36, the air upper supply pipe 290 is rotatably formed by the movable device 320 for the air upper supply pipe.
That is, the movable device 320 for the air upper supply pipe includes, for example, an air cylinder 322 as an actuator. The main body of the air cylinder 322 is supported by, for example, a clevis-shaped cylinder support portion 324 on, for example, the left inner wall surface 124B of the drying booth 124. In this case, one end of the air cylinder 322 on the main body side is rotatably supported by the cylinder support portion 324 by the support shaft 324a. Further, the tip of the rod 322a of the air cylinder 322 is rotatably supported by the knuckle joint 326 by the support pin 328.

Therefore, by driving the movable device 320, the air upper supply pipe 290 can swing at a predetermined angle so as to be able to approach and separate from the work W as shown in FIGS. 35 and 36. It has become. In this case, as shown in FIG. 35, the air upper supply pipe 290 can rotate upward at an angle of, for example, 45 ° so as to be separated from the work W, and from that state, as shown in FIG. 36, air can be rotated. It is possible to rotate the air upper supply pipe 290 in a horizontal state so that the upper supply pipe 290 is brought close to the work W and is arranged so as to face the air lower side supply pipe 122.

The washing machine 110 is provided with a control panel 150 that appropriately controls the above-mentioned various devices and various mechanisms on the side surface side of the booth 120.

Next, with respect to a series of movements in which the above-mentioned washing machine 110 cleans the deposits (foreign matter) such as cutting fluid and chips adhering to the work W and further dries them, FIGS. 21 to 36, 37 and 38. Etc. will be briefly explained with reference to.
That is, first, the work W is arranged in the drying booth 124 of the washing machine 110. In the washing machine 110, the work W is initially placed on the jig 52 arranged in the jig receiving portion 204 of the work transfer device 190 arranged at a predetermined position in the drying booth 124 with the front door 126 open. It is set (see step S1 in FIG. 38). Next, the start button of the control panel 150 is pressed (see step S2 in FIG. 38). In this case, the operation of the brake mechanism 10 is released and the state is turned off (see step S3 in FIG. 38). Then, the work W is transported from the drying booth 124 to the cleaning booth 122 by the work transport device 190, and the partition door 128 and the front door are closed (see step S4, step S5, step S6 and step S7 of FIG. 38). ).

Then, the cleaning liquid pump 138 is started, and in the cleaning booth 122, the cleaning liquid is ejected by the plurality of cleaning nozzles 248 to 260 to start cleaning (see step S8 in FIG. 38). After that, when a predetermined time elapses, the cleaning combination pump 138 is stopped, and cleaning of the work W is completed (see step S9 in FIG. 38).
Next, the first pre-drying blow nozzle 264 and the second pre-drying blow nozzle 266 start rough blow / pre-drying, that is, after air is injected into the work W, rough blow / pre-drying ends. (See step S10 and step S11 in FIG. 38). Then, the partition door 128 is opened (see step S12 in FIG. 38), the washed work W is again conveyed to the drying booth 124 by the work transfer device 190, and then the partition door 128 is closed (FIG. 38). See step S13, step S14 and step S15 of.).

Then, in the drying booth 124, the air upper supply pipe 290 is rotated downward by the movable device 320 and approaches the work W side (see step S16 in FIG. 38). Then, in the drying booth 124, the main drying of the work W is started (see S17 in FIG. 38), the air upper supply pipe 290 is arranged above the work W, and the air lower supply pipe is arranged below the work W. 282 is arranged, air is jetted to the work W by a plurality of blow nozzles 298 to 312, the cleaning liquid remaining on the work W is blown off, and the work W is dried. The work W is rotated by the first blow nozzles 298 to the sixth blow nozzles 312 and the jig rotation imparting blow nozzle 313 (accelerator air blow nozzle) for drying the work W. Further, the rotation speed of the work W is managed by the set value of the ON / OFF cycle of the rotation detection sensor 70. In this case, the injection of the air blow by the jig rotation imparting blow nozzle 313 is stopped at the upper limit of the set value, and the injection of the air blow by the jig rotation imparting blow nozzle 313 is started at the set value limit.

When the drying process is completed, the mist collecting device 130 is activated, and the mist in the washing booth 122 and the drying booth 124 is sucked and collected.
When the drying process is completed, the injection of air from the jig rotation imparting blow nozzle 313 (accelerator air blow nozzle) is stopped, and the main drying is completed (see step S18 in FIG. 39). At this time, the brake mechanism 10 is turned on, that is, the brake mechanism 10 is activated (see step S19 in FIG. 39), and the rotation of the jig 52 becomes low, for example, 30 rotations or less per minute (see step S19 in FIG. 39). (See step S20 in FIG. 39), after that, the rotation of the jig 52 is stopped and the rotation of the work W is also stopped. Then, the operation of the brake mechanism 10 is released, and the state is turned off (see step S21 in FIG. 39).

Then, the positioning mechanism 50 is operated, and the positioning claw 82 advances toward the blade portion 58 of the jig 52 by the positioning claw operating means 88, and at the same time, air is injected from the jig rotation imparting blow nozzle 313 (accelerator air blow nozzle). (See step S22 in FIG. 39). Then, when the positioning claw 82 enters the peripheral space SP below the jig 52 (see, for example, FIG. 7) and the positioning claw 82 does not abut on the top surface 61B of the positioning blade portion 60 (step S23 in FIG. 39). In (see), the sensor (cylinder switch) of the air cylinder detects that the extension of the piston rod 88A of the positioning claw operating means 88 (air cylinder) is completed and the advancement of the piston rod 88A is completed (FIG. 39). See step S24.). At this time, the jig 52 is rotated, that is, the work W is rotated (see step S25 in FIG. 39).

In this case, when the jig 52 is rotated clockwise, for example, the positioning claw 82 hits the side surface 61C of the positioning blade portion 60, and when the jig 52 is rotated counterclockwise, for example, the positioning claw 82 hits the side surface 61D of the positioning blade portion 60. (See step S26 in FIG. 39). When the positioning claw 82 hits the side surface 61C or 61D of the positioning blade portion 60, the injection of air from the jig rotation imparting blow nozzle 313 (accelerator air blow nozzle) is stopped (see step S27 in FIG. 39), and further. The brake mechanism 10 is turned on, and the brake mechanism 10 is activated (see S28 in FIG. 39).

After that, the positioning claw 82 of the positioning mechanism 50 is retracted by the positioning claw operating means 88. Then, when the piston rod 88A of the positioning claw operating means 88 (air cylinder) is reduced and the retreat of the piston rod 88A is completed, the front door 126 opens (see step S29 in FIG. 39). At this time, the work W held by the jig 52 is stopped at a predetermined position in the drying booth 124 and is positioned at a predetermined position (see the end of FIG. 39). ). In this case, when the rotation of the work W is stopped, the rotation detection sensor 70 is maintained in the ON state, so that the work W is held at a predetermined position positioned by the positioning mechanism 50. It has become.

On the other hand, returning to step 22 of FIG. 39, the positioning claw 82 advances toward the blade portion 58 of the jig 52 by the positioning claw operating means 88, and at the same time, air is also discharged from the jig rotation imparting blow nozzle 313 (accelerator air blow nozzle). When the injection is performed, the positioning claw 82 enters the circumferential space SP below the jig 52 (see, for example, FIG. 7), and the positioning claw 82 comes into contact with the top surface 61B of the positioning blade portion 60 (FIG. 39). In step S31), the extension of the piston rod 88A of the positioning claw operating means 88 (air cylinder) is not completed, and the sensor (cylinder switch) of the air cylinder does not detect that the advance of the piston rod 88A is completed. (See step S32 of FIG. 39.). At this time, whether or not the sensor (cylinder switch) of the air cylinder detects that the extension of the piston rod 88A is completed even after a predetermined time (for example, 2 seconds) has elapsed by the timer (see step S33 in FIG. 39). That is, it is determined whether or not the sensor (cylinder switch) of the air cylinder has detected that the extension of the piston rod 88A of the positioning claw operating means 88 (air cylinder) is completed and the advancement of the piston rod 88A is completed ( See step S34 in FIG. 39).

Here, when the sensor (cylinder switch) of the air cylinder detects that the advancement of the piston rod 88A is completed, the process returns to step S24 of FIG. 39.
On the other hand, if the extension of the piston rod 88A of the positioning claw operating means 88 (air cylinder) is not completed and the sensor (cylinder switch) of the air cylinder does not detect that the advance of the piston rod 88A is completed, the positioning claw is used. The 82 is retracted by the positioning claw operating means 88 (air cylinder) (see step S35 in FIG. 39), and returns to step S22 in FIG. 39.

In the washing machine 110 according to the embodiment of the present invention, in particular, since the brake mechanism 10 and the positioning mechanism 50 are arranged, in the brake mechanism 10, the pivot portion 12 is rotatable by the pivot portion support 18. It is supported, and a brake 36 piece is fixed to the pivot support 18. When the brake piece 36 is pressed by, for example, a pin cylinder 34 as a pressing means, the brake piece 36 can rotate around the pivot portion 12 in the circumferential direction (rotation direction) of the pivot portion 12. Therefore, by rotating the brake piece 36 and bringing the brake piece 36 into contact with the second shaft-shaped portion 54b of the jig 52, the rotation of the jig 52 is dampened and stopped. Therefore, the rotation of the work W can be stopped.

Further, in the washing machine 110 according to the embodiment of the present invention, in the work W whose rotation is stopped by the brake mechanism 10, the positioning claw 82 is rotated around the jig 52 by the air cylinder of the positioning claw operating means 88 at the rotation stop position. It is inserted into the space SP. In this case, when the jig 52 is rotated by the jig rotation imparting blow nozzle 313, the rotation of the jig 52 is stopped at the position where the positioning claw 82 is in contact with the positioning blade portion 60. That is, according to the washing machine 110, the work W can be stopped at a position where it comes into contact with the side surfaces 61C to 61D of the positioning blade portion 60 of the positioning jig 52, and can be positioned at a predetermined position.
Therefore, in the washing machine 110 according to the embodiment of the present invention, the work W after washing can be stopped at a constant stop position, and the handling of the industrial robot can be surely and stabilized. It is suitable for automation.

FIG. 34 schematically shows an example of cleaning means for cleaning the work W by attaching the work W shown in FIG. 31 to the jigs shown in FIGS. 6 to 8 in the cleaning booth 122 of the cleaning machine 110. It is explanatory drawing which shows.
Compared with the cleaning means shown in FIG. 33, this cleaning means has, in particular, a rotation imparting cleaning nozzle 356 that injects a cleaning liquid onto the blade portion 58 of the jig 52 to apply a rotational force to the work W, and air to the blade portion 58. The difference is that a rotation imparting blow nozzle 358 that injects the work W to impart a rotational force to the work W is provided.
The cleaning means of the cleaning machine 110 includes a cleaning liquid supply piping unit 350, and the cleaning liquid supply piping unit 350 includes a cleaning liquid lower supply pipe 352 and a cleaning liquid upper supply pipe 354. The cleaning liquid lower supply pipe 352 includes a first cleaning nozzle 360, a second cleaning nozzle 362, a third cleaning nozzle 364, a fourth cleaning nozzle 366, and a fifth cleaning nozzle 368. In this case, the first cleaning nozzle 360 sprays the cleaning liquid into the gap 344 between the bottom surface of the work W and the work pedestal portion 56 of the jig 52 by the spacer member 342 of the jig 52. The second cleaning nozzle 362, the third cleaning nozzle 364, the fourth cleaning nozzle 366, and the fifth cleaning nozzle 368 are sprayed onto the concave portion g, the convex portion h, and the boundary i of the concave-convex portion of the work W, respectively. It has become a thing.

When this cleaning means is used, in the cleaning booth 122, in addition to the configuration in which the cleaning liquid is ejected from the rotation imparting cleaning nozzle 254 to the work W and the injection pressure imparts a rotational force to the work W, the jig rotation is further imparted. The cleaning liquid is ejected from the cleaning nozzle 356 to the blade portion 58 of the jig 52, and the injection pressure is used to apply a rotational force to the work W via the jig 52. Further, in the drying booth 124, in addition to the configuration in which air is injected from the rotation imparting blow nozzle 312 to the work W to apply a rotational force to the work W by the injection pressure, the blades of the jig 52 are further applied from the rotation imparting blow nozzle 358. Air is injected into the portion 58, and the injection pressure gives the work W a rotational force via the jig 52.
Therefore, when this cleaning means is used, the rotational force of the work is increased by the synergistic effect of the rotation imparting cleaning nozzle 254 and the rotation imparting cleaning nozzle 356 for jigs, and in the drying booth 124, the rotation imparting blow nozzle 312 and rotation Due to the synergistic effect of the imparting blow nozzle 358, the rotational force of the work W is increased.

The mist collecting device 130 includes the collecting device main body 370 as shown in FIGS. 21 and 25 (A) and the like. The drying booth 124 has a suction port 372 on the upper surface of its inner wall. A suction duct hose 374 is arranged between the suction port 372 and the collection device main body 370. The mist collecting device 130 separates the mist and dust contained in the sucked air from the air, and the separated mist and dust are dropletized and discharged from the drain (not shown). NS. Further, the separated air is exhausted to the atmosphere from the exhaust port.

FIG. 21 is a schematic front view showing an example of ventilation means arranged in the drying booth of this washing machine and its arrangement. 37 is an explanatory view showing a main part of the ventilation means shown in FIG. 21, FIG. 37A is an enlarged view of a partial notch of FIG. 21, and FIG. 37B is an outline of the main part of FIG. 21A. It is a perspective view.
The ventilation means 380 has a ventilation port 382 on the inner wall on the right side surface of the drying booth 124 of the upper booth 120, and the ventilation port 382 is covered with a ventilation port cover 384. The vent cover 384 includes a front wall 384a, a left side wall 384b, a right side wall 384c, and an upper surface wall 384d. On the upper surface wall 384d, a mounting piece 384e for mounting the vent cover 384 on the inner wall on the right side surface of the drying booth 124 is integrally formed. Further, the vent cover 384 has an outside air introduction port 386 for taking in outside air from the vent 382 below the vent cover 384.

In this case, the suction force when sucking mist from the inside of the drying booth 124 via the suction duct hose 374 may cause deformation of the inner wall surface of the drying booth 124 and suction noise. Since the air is ventilated by the vent 382, the drying booth 124 is prevented from being deformed due to such a change in air pressure, and a sound deadening effect on the suction sound can be obtained. Further, since fresh air can be taken into the drying booth 124 from the outside through the vent 382, the drying effect in the drying booth 124 is also high.

In this washing machine 110, in particular, in the washing booth 122, the boundary i between the concave portion g, the convex portion h, the concave portion g and the convex portion h of the work W from the upper side and the lower side of the work W by the plurality of cleaning nozzles 248 to 260. The cleaning liquid is separately sprayed toward the surface. Further, in the drying booth 124, the concave portion g, the convex portion h, the concave g portion and the convex portion of the work W are cleaned from the upper side and the lower side of the work W washed by the plurality of blow nozzles 298 to 312 in the previous cleaning booth 122. Air is separately injected toward the boundary i of the portion h.
Therefore, this cleaning machine 110 sufficiently cleans foreign substances such as cutting oil and chips adhering to a work W having a complicated shape having uneven portions including steps, grooves, holes, notches, gaps, and the like. And can be dried. In this case, the number, arrangement, and injection direction of the cleaning nozzles and blow nozzles can be appropriately changed according to the size of the work W and the shape of the uneven portion.

Further, in the cleaning machine 110, in the cleaning booth 122, a cleaning liquid is ejected from the cleaning nozzle 254 having a function as a rotation-imparting cleaning nozzle to the work W, and a rotational force is applied to the work W by the injection pressure. Further, in the drying booth 124, air is injected into the work from the blow nozzle 312 having a function as a rotation imparting blow nozzle, and a rotational force is applied to the work by the injection pressure.

Further, in the washing booth 110, the work W is pre-dried by the pre-drying blow nozzles 264 and 266 before the washed work W is transported from the washing booth 22 to the drying booth 124. In this case, the pre-drying blow nozzle 164 also has a function of injecting air into the washed work W and applying a rotational force to the washed work W by the injection pressure.
That is, in this washing machine 110, the washed work W is pre-dried by the pre-drying blow nozzles 264 and 266 before being conveyed from the washing booth 122 to the drying booth 124, so that the work W is dried in the drying booth. At 124, it can be dried more effectively. Further, since the pre-drying blow nozzle 264 also has a function of applying a rotational force to the work W, it is not necessary to separately provide a rotation imparting blow nozzle for applying a rotational force to the work W.

Further, in this washing machine 110, for example, as shown in FIG. 34, when the work W is placed on the work pedestal portion 56 of the jig 52, the spacer member 342 causes the bottom surface of the work W and the work pedestal portion 56 to be connected to each other. It is configured to have a gap 344 between them. Therefore, in cleaning the work W in the cleaning booth 122 and drying the work W in the drying booth 124, there is no so-called blind spot where the bottom surface of the work W is hidden by the work pedestal portion 56, and the cleaning nozzle in the cleaning booth 122. Since the cleaning liquid can be injected from 248 to 260 and the air from the blow nozzles 298 to 312 in the drying booth 124 can be injected into the gap portion 344 between the bottom surface of the work W and the work pedestal portion 56, respectively, the bottom surface of the work W can be injected. It is possible to cleanly remove the adhering matter (foreign matter) such as cutting fluid and chips adhering to the gap 344 from the gap portion 344.

In this cleaning machine 110, the cleaning nozzles 248 to 260, the blow nozzles 298 to 312, the rotation-imparting cleaning nozzle 356, the rotation-imparting blow nozzle 358, and the pre-drying blow nozzles 264 and 266 are flexible tubes whose tips are bendable. In the cleaning booth 122, it is possible to appropriately adjust the injection direction of the cleaning liquid from the cleaning nozzles 248 to 260 and the rotation-imparting cleaning nozzle 356, and the work W can be efficiently cleaned. Further, in the drying booth 124, the injection direction of air from the blow nozzles 298 to 312 and the rotation imparting blow nozzle 358 can be appropriately adjusted, and the work W can be dried efficiently.

Further, in this cleaning machine 110, since the air upper supply pipe 290 can approach and separate from the work W, the work W is transported from the cleaning booth 122 to the drying booth 124 by the work transfer device 190 and arranged. Occasionally, the air upper supply pipe 290 can be moved away from the work W to a position where the air upper supply pipe 290 does not interfere with the rail portion 194 of the work W, and when the work W is dried in the drying booth 124, the work The air upper supply pipe 290 can be brought close to the work until the position where W is effectively dried.

Further, since the washing machine 110 is provided with front side casters 152A and 152B and rear side casters 154A and 154B as moving means for making the washing machine 110 movable, it is incorporated into the production line where the work W is manufactured. It can be unitized so that it can be used.

In this washing machine 110, a gradient is formed on the bottom surfaces of the washing booth 122 and the drying booth 124 of the upper booth 120 so as to be lowered from the back side to the front side when viewed in the longitudinal direction. .. Further, the bottom surface of the drying booth 124 is formed with a slope that inclines so as to decrease from both sides in the width direction toward the center. Further, the drying booth 124 has, for example, a through hole (not shown) having a rectangular shape in a plan view in the central portion of the bottom surface thereof.
Therefore, in the cleaning liquid booth 122 and the drying booth 124, the sewage when the foreign matter adhering to the work W is removed flows into the drying booth 124 from the back side to the front side of the upper booth 120, and further, through the through hole. Therefore, it flows into the cleaning liquid storage tank 132 of the lower booth 118.

Further, in this cleaning machine 110, since the amount of liquid in the cleaning liquid storage tank 132 is detected and managed by a sensor (not shown), it is possible to prevent temperature abnormality and empty operation due to empty heating when the cleaning liquid is insufficient. .. Moreover, the cleaning liquid in the tank can be automatically heated by calculating back from the start time. Further, in the washing machine 110, for example, the washing time and the drying time are set by back calculation from the time from the start to the end of processing / washing of one work W.
