Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cleaning device, and more particularly, the present invention relates to a cleaning device, and more specifically, a cleaning unit equipped with a nozzle block for delivering a cleaning fluid to a workpiece is configured to be detachably attached to a main body. The present invention relates to a cleaning device configured to easily clean a wide variety of different types of workpieces.

For example, when cutting is performed on a cast product, etc. that constitutes an engine, such as drilling a jacket hole in a cylinder block, the cutting waste generated by the cutting must be effectively removed to the outside.

Conventionally, in the automobile industry, cleaning devices have been employed to automatically remove cutting debris from relatively large workpieces such as cylinder blocks. This type of cleaning device consists of a liquid cleaning device and an air blow device.

That is, a line is extended from the cutting device on the upstream side to the downstream side, and the tunnel mechanism is arranged along this line. Inside this tunnel mechanism, a liquid cleaning device and an air blowing device are placed separated by a predetermined distance.

Therefore, it is cut by a cutting machine, and for this reason,
A workpiece with cutting debris adhered to it is introduced into the tunnel, and first, the liquid cleaning device is energized. As a result, the cutting debris is washed away, and then the air blowing device blows out air at a predetermined pressure to the workpiece that has arrived just before the air blowing device, which further blows out the adhering cutting debris together with the cleaning fluid. It will be dropped. In this case, the liquid cleaning device and the air blowing device are each equipped with a plurality of nozzles that spray liquid and air onto the workpiece, and the number of nozzles varies depending on the type of workpiece to be cleaned. The ejection part is configured to be movable.

Therefore, when different models of workpieces are to be flowed on the same production line, the positions of the nozzle of the liquid cleaning device and the nozzle of the air blowing device must be changed depending on the shape of the workpieces. In conventional equipment, the nozzle is fixed in both the liquid cleaning equipment and the air blowing equipment, and in today's system of producing many types of small quantities of work on the same line, the nozzle must be replaced each time. It has been pointed out that this requires a temporary stoppage of the line, and that the replacement work, such as adjusting the jetting angle of the nozzle, is complicated and takes a long time.

The present invention has been made in order to overcome the above-mentioned disadvantages, and has a cleaning unit having a plurality of nozzle blocks corresponding to each workpiece that can be detachably attached to the main body of the cleaning apparatus to automatically perform automatic operation using a single apparatus. To provide a cleaning device that can clean different types of workpieces by replacing the cleaning unit easily and in a short time.

The cleaning device according to the present invention is basically constructed as described above, and its operation and effects will be explained next.

First, when the work W1 arrives at the end of the first housing 12 by a transport device (not shown), the cylinder 28 is energized.
The pedestal 34b, which is engaged with the cylinder rod 28a of the cylinder 28, rises together with the holding member 40b to support the workpiece W1. In this case, a nozzle block 42b is fixed to the upper part of the holding member 40b, and this nozzle block 42b engages with the bottom of the workpiece WI to firmly hold it. Then, the cylinder 28 is driven again and the workpiece WI is lowered.

b, and engages with the conveyance table 30b. Next, the conveyor table 30b moves the rollers 32b, 32b on the rail member 22.
is transported by a drive device (not shown), and the second housing 14
It is moved to just below. At this time, the cylinder rod 28a is slightly lowered and disengaged from the pedestal 34b in advance. Due to this movement of the conveyance table 30b, the second housing 1 has already been moved.
The conveyance table 30a, which was positioned directly below the cylinder 4, moves to the cylinder 24 side. Note that the conveyance table 30b is the conveyance table 30b.
Since the same operations are performed in relation to the second housing 14 and the transport table 30a, the transport table 30a will be described here.

The pedestal 34a that engages with the conveyor table 30a on the cylinder 26 is driven by the cylinder rod 26a under the driving action of the cylinder 26.
performs a rising operation, and therefore rises toward the second casing 14 side.

Since the nozzle block 42a is positioned on the holding member 40a disposed on the pedestal 34a, the work w2 on the nozzle block 42a enters the inside of the second housing 14, that is, the cleaning unit 150c. When it reaches a predetermined position, the cylinder 54 is energized and the supply pipe 48 is displaced in the horizontal direction together with the joint 52, so that the fluid passage 46 of the nozzle block 42a and its tip end engage with each other. At the same time, the nozzle block 42a is sufficiently clamped and positioned by the engagement of the supply tube 48.

Next, the work clamp cylinder 58 and the work clamp cylinder 60 facing it are driven, and the work clamp cylinder 58 displaces the cylinder rod 58a in the horizontal direction, and the cylindrical body 66a is inserted into the cylindrical conduit 144c of the nozzle holding member 146c.

is biased to displace the shaft 64b, and the sliding member 67b of the cylindrical body 66b presses the nozzle block 163e in the same manner as described above, and firmly engages with the other side of the workpiece W2. That is, the workpiece W2 is held in the workpiece clamp cylinder 58.
and 60. In this case, the gear 78 of the motor 74 is in mesh with the gear 70, but since this gear 70 slides on the spline 68 carved in the shaft 64b, the mesh between the gears 70 and 78 can be disengaged. There isn't.

In the above configuration, if the cylinder 82 into which the fluid supply pipe 80 is inserted is driven to move in the horizontal direction,
The tip end fits into the cylindrical conduit 104c. Therefore, if the cleaning liquid is supplied from the fluid supply pipe 80, this cleaning liquid will pass through the fluid supply pipe 80 as shown by the arrow and pass through the pipe line 104c.
The liquid enters the passageway 92c through the hole 108 and reaches the passageway 110c through the opening 94c. Since this passage 110c communicates with the cylindrical pipe line 144c, cleaning liquid is sprayed onto the workpiece Wt from the nozzle blocks 163e and 163f. On the other hand, aisle 11
0c is connected to passages 116a and 116b. Therefore, the cleaning liquid reaches the passages 124b and 126a,
Nozzle blocks 166e, 16 communicating with the respective passages
The cleaning liquid is similarly poured onto the workpiece W2 from 6f. Moreover, since the cleaning liquid is also poured into the nozzle block 164C from the passage 92c of the shaft 84 via the pin member 96c, the cleaning liquid is eventually supplied from the supply pipe 80 to the five surfaces of the workpiece W2. It turns out.

At the same time, cleaning liquid is also supplied from the fluid supply pipe 48 to the nozzle block 42a through the passage 46. This cleaning liquid is useful for removing cutting debris from the lower surface of the workpiece W2.

When the first cleaning step is completed after a predetermined period of time has elapsed,
The cylinder 26 is driven again and the cylinder rod 26a
descends. As a result, the nozzle block 42a and the workpiece W2 held therein integrally move downward to a predetermined position. During this time, the supply of cleaning liquid from the fluid supply pipe 80 to the shaft 84 is stopped. Next, the cylinder 82 is energized and the fluid supply pipe 80 performs a withdrawal operation, and its distal end disengages from the conduit 104C of the cleaning unit holder 100a. In the same way, the cylinder 54 also performs a clocking-out operation, and the supply pipe 48 separates from the nozzle block 42a.

Thereafter, the motor 88 is driven to rotate, thereby causing the shaft 84 and the cleaning unit holders 100a, 100b to rotate integrally. As a result, the next stage cleaning unit 15
0b occupies the bottom. Next, the cylinder 26 is driven again and the workpiece W2 is raised. Then, the work clamp cylinders 58, 60 are energized again, and the cylindrical body 66
The sliding members 67a and 67b of a and 66b are respectively connected to the cylindrical body 102b of the cleaning unit holders 100a and 100b.
, 102b, and the workpiece W! to clamp.

In such a state, the cylinder 26 performs a clock-out operation, and the workpiece W2 is eventually moved to the workpiece clamp cylinder 58.
It is held in a hollow state while being clamped by 60.

At this time, the fluid supply pipe 80 is connected to the pipe line 104b under the driving action of the cylinder 82, and then the fluid supply pipe 80 supplies the cleaning liquid into the shaft 84 again. Similarly to the above, the nozzle block 16 is applied to the workpiece W2 through the passage.
3c.

Cleaning liquid is supplied from 163d, 164b and 166C1166d, and the cleaning liquid is ejected from the side and upper end of the workpiece.

In this case, the motor 74 is driven to rotate the shaft 64b via a gear 78 that is attached to the rotational drive shaft. Since the cylindrical body 66b connected to the tip of the shaft 64b is engaged with the nozzle holding member 146b, when the shaft 64b rotates, the nozzle holding member 146b also rotates, and furthermore, it is integrally connected to the nozzle blocks 163C and 163d. The workpiece W2 also rotates.

That is, the second step of cleaning the workpiece W2 while rotating it is performed.

Furthermore, when the second cleaning step is completed in this way, the cylinder 26 is driven again to start the operation of holding the workpiece W2. That is, the cylinder 26 is energized to lower the workpiece W2 to a predetermined position. Then,
The motor 8B is rotationally driven to rotate the shaft 84, and the nozzle block 163a in the next cleaning unit 150a,
163b, 164a.

166a, 166b, etc. occupy the lowest positions. In this state, the cylinder 26 is energized and the workpiece W2 is
is raised to a predetermined position, and then the workpiece clamp cylinders 58, 60 and cylinder 82 are driven to clamp the workpiece W2 and connect the air supply system to the cleaning unit holder 1.
Connect to 00a and 100b.

That is, air is now supplied from the fluid supply pipe 80, and the nozzle blocks 163a, 163b, 164a
, 166a, 166b, and 42a, air at a predetermined pressure is ejected onto the workpiece W2, removing the cleaning fluid together with the cutting waste (
3rd step). This operation is performed by the cleaning unit 150d.
Inside nozzle block 163g, 163h.

164d, 166g, and 166h to complete four steps. Note that in the fourth step, as in the second step, the nozzle block 16 is moved under the driving action of the motor 74.
This is done by rotating the work W2 integrally with 3g and 163h. Also, at this time, the nozzle block 42
No air is blown out from a.

When the cleaning process is completed as described above, the cylinder 26
As a result, the workpiece W2 is seated in the hole 36a of the conveyor table 30a together with the nozzle block 42a and the holding member 40a. Therefore, by driving a conveyance device (not shown) in the horizontal direction, the rollers 32a, 3 of the conveyance table 30a can be moved.
2a moves on the rail member 22 and reaches the delivery part. During this time, the workpiece W is newly held on the conveyor table 30b.

reaches directly above the cylinder 26 as described above.

On the other hand, when the cylinder 24 is driven, the cylinder 24
The cylinder rod 24a raises the workpiece W2 to the outside of the housing 12 together with the nozzle block 42a, and takes it out via a transport device (not shown). Note that during this time, the mist collector 230 is constantly energized.
Housing 12) The cleaning liquid and compressed air mist inside the housing 14 can be effectively discharged.

Normally, the same type of workpiece is cleaned by the process described above, but when the type of workpiece to be cleaned is changed, the cleaning unit 150a is replaced with a new cleaning unit 150e. I will explain about it. In the figure, reference numerals 156i and 156j indicate locking members fixed to both sides of the cleaning unit 150e.

Therefore, first, the motor 17 provided in the conveying device 170
8, the rack 188 that meshes with it will move in the direction of arrow C.
Therefore, the moving platform 1B2 integral with this is also displaced in the direction of arrow C. Therefore, the gripping stand 200 is operated so as to be positioned vertically above the cleaning unit 150a. Next, when the cylinder 192 is driven and the cylinder rod 198 extending therefrom is displaced vertically downward, the gripping base 2 attached to the tip of the cylinder rod 198 is moved.
00 is similarly displaced vertically downward. When the gripping base 200 is lowered in this way, the tips 212a and 212b of the pillars 210a and 210b fixed to both sides of the gripping base 200 move toward the slide members 132 disposed inside the housings 132a and 132b.
a, 134b, and come into contact with slopes 138a, 138b.

When the gripping base 200 is further lowered, the tip portion 21
2a, 212b press the slide members 134a, 134b downward, and furthermore, the respective tip portions 212a, 21
2b and slide members 134a, 134b are slopes 213
a, 213b and slopes 138a, 138b, the slide members 134a, 134b are pressed in the direction away from the cleaning unit 150a, respectively, and the spring 136 in the housing 132a and the spring (not shown) in the housing 132b are pressed. Displaces against the elastic force. Therefore, when the gripping table 200 is stopped at a predetermined height position, the slide members 134a and 134b are held apart from the cleaning unit 150a. Here, when the cylinder 202 is driven, the clamp claw 20
8a to 208d are vertically oriented and inclined, and each through hole 161a is bored in the cleaning unit 150a.
to 161d. Therefore, when the cylinder 192 is driven to raise the holding table 200, the cleaning unit 15
0a is engaged with the clamp claws 208a to 208d and released from the engagement relationship with the slide members 134a and 134b, so that they rise integrally.

Further, while the cylinder 192 is driven to stop the gripping table 200 at a predetermined height position, the movable table 182 is displaced in the direction indicated by the arrow under the driving action of the motor 178.

During this time, in the storage device 172, the motor 216 is driven to rotate the rotary drive shaft 220, and among the side surfaces 224a to 224d of the mounting base 222, for example, 224a is positioned at the uppermost position. In this case, the cleaning unit) 150a
The engaging member 160a fixed to the side surface 22 of the mounting base 222
In order to fit between a pair of locking members 226a and 226b fixed to the side surface 22a, the position detection device 228
4a must be accurately positioned horizontally.

In this way, when the moving table 182 is displaced in the direction indicated by the arrow, the engaging member 160a fixed to the cleaning unit 150a is fitted between the locking members 226a and 226b fixed to one side 224a of the mounting table 222. do. Therefore,
The moving unit 182 is stopped at a predetermined position, and the cylinder 202 is driven to horizontally displace the clamp claws 208a to 208d to tilt the cleaning unit.
150a and the gripping base 200 are disengaged.

In the above state, the motor 178 is further driven to displace the moving table 182 in the direction of arrow C and stop it at a predetermined position. Next, the motor 216 is driven to move the mounting base 222.
150e is positioned at the top. Furthermore,
The motor 178 is driven to move the moving table 182. is displaced in the direction of the arrow and stopped above the cleaning unit 150e, and then the clamp claw 208 is moved under the driving action of the cylinder 202.
a to 208d are engaged with respective predetermined holes, and the gripping base 2 is
00 holds the cleaning unit 150e. Therefore, by driving the motor 178 to position the movable table 182 vertically above the main body 10, and then driving the cylinder 192 to lower the gripping table 200, the bin member 96a can be attached to the cleaning unit 150e. The cleaning unit 150e is positioned by fitting into the hole that is not provided. Furthermore, in this case,
The slide members 134a, 134b are attached to the tips 212a, 2 of the pillars 210a, 210b fixed to the gripping base 200.
It is held in contact with 12b. Therefore, the cylinder 202
After removing the clamp claws 208a to 208d from the holes in the cleaning unit 150e, the cylinder 19
2 to raise the gripping base 200, the tips 212a, 212b also rise, and the slide members 134a,
134b and thus said slide member 134
a and 134b are displaced toward the cleaning unit 150e by the elastic force of the spring 136 and the spring (not shown) of the housing 132b, and lock the distal end slopes 140a and 140b of the locking member 1.
56i, 156j, the cleaning unit 150e has cleaning unit holders 100a, 100b.
is maintained.

Next, the motor 88 is driven to rotate the shaft 84 to position the next cleaning unit (150d) at the top. Therefore, the cleaning unit 150d is stored in a predetermined position in the storage device 172, and a new cleaning unit (not shown) is attached to the shaft 84 in the same manner as the replacement work described above. Furthermore, the cleaning units 150c and 150b are also replaced with predetermined cleaning units using the same procedure. In this way, after a cleaning unit corresponding to a new workpiece is attached to the shaft 84, a new nozzle block 42b corresponding to the lower part shape of a predetermined workpiece is prepared, and the workpiece is placed on this nozzle block 42b. The workpiece is cleaned through the steps described above and is finally delivered to the outside.

By the way, when cleaning many types of workpieces, it is desirable that the nozzle blocks 42a, 42b are also quickly replaced in accordance with each workpiece. Therefore, in order to meet such demands, it is preferable to adopt, for example, a nozzle block exchange mechanism shown in FIG. 8.

That is, in the figure, a holding member 231 is removably engaged on a pedestal 34a that engages with a cylinder rod 26a. A nozzle block holder 234 is rotatably supported in the horizontal direction by support parts 232a and 232b that bulge upward from both ends of the holding member 231 via bearings. In this case, the support portion 232a engages with the guide member 38a. Further, the nozzle block 23 that comes into contact with the lower surface of each workpiece is attached to the outer peripheral part of the nozzle block holder 234.
6a to 236c and nozzle blocks (not shown) are fixed. Further, a first engaging portion 240 having a predetermined shape is provided at the other end of the rod 238 extending from one end of the nozzle block holder 234.

Next, when the pedestal 34a is located at the lowest end, the rod 2
A cylinder 242 is disposed coaxially with 38. Under the action of the cylinder 242, the shaft 2 is displaced in the direction of the arrow in the figure.
41 is provided with a gear 246, and a second engaging portion 24 corresponding to the first engaging portion 240 is provided on the other end side of the gear 246.
8 is formed. Therefore, the gear 246 meshes with a gear 254 that is rotatably attached to the rotational drive shaft 252 of the motor 250.

In such a configuration, the cylinder rod 26a is moved downward under the driving action of a cylinder (not shown) to position the pedestal 34a at the lowest end. Next, the cylinder 242 is driven to displace the shaft 241 to the left in the figure to engage the respective engaging portions 240 and 248. Therefore, when the motor 250 is driven to rotate the engaging portion 248 through the gears 254 and 256, the nozzle block holder 234
rotates, and the nozzle block 236b is located at the top. Further, after stopping the motor 250, the cylinder 242
to displace the shaft 244 to the right and engage the engaging parts 240 and 2.
48, the positioning of the nozzle block 236b corresponding to the new workpiece is completed.

Therefore, when cleaning many types of workpieces, if the nozzle block holder 234 is rotated as described above and a predetermined nozzle block 236b or 2360 is positioned at the top, it is possible to clean each workpiece very easily. This also makes it possible to automate the work.

As described above, according to the present invention, nozzle blocks corresponding to different types of workpieces are fixed to the cleaning unit, and the cleaning unit is configured to be automatically attachable and detachable, so that the type of workpieces to be cleaned can be changed. Even if there are many workpieces, if cleaning units with nozzle blocks corresponding to the shape of each workpiece are stored in the storage device, cleaning units corresponding to various workpieces can be taken out very easily and in a short time, and these can be automatically removed. It can be exchanged. Therefore, even if the types of machines are extremely wide, it is possible to perform the cleaning action continuously without stopping the line, which further improves work efficiency.

Although the present invention has been described above with reference to preferred embodiments, the present invention is not limited to these embodiments, and various improvements and changes in design are possible without departing from the gist of the present invention. Of course.
