Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a rotary type washing machine suitable for batch washing of machine parts.

[0002]

2. Description of the Related Art Machine parts produced in small quantities of a wide variety of products are not suitable for processing by a continuous automatic cleaning device, and thus have been processed by a batch type cleaning tank. If all the steps of washing, hot water washing and drying are carried out with one washing tank, the work can be put in and out only once, so the number of man-hours in the middle is small and the work place is not likely to be contaminated by washing liquid. There is a problem that the time required for the treatment is long because it is necessary to change the washing liquid and hot water every time the temperature changes.

If several cleaning tanks are used and each cleaning tank is specialized for a cleaning process, a hot water cleaning process, or a drying process, the cleaning liquid and hot and cold water can be circulated and the processing time can be shortened. However, there is a problem that the intermediate transfer of the work requires manpower and the work place is contaminated by the washing liquid during the transfer.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and its purpose is to remove and insert a work piece only once and to keep the work place dirty by washing liquid. The object is to provide a batch type cleaning device for mechanical parts which does not have such a process and takes a relatively short time.

[0005]

An intermediate partition is provided to provide a processing space for rinsing and drying, a hydraulic cylinder is erected in the center, and a vertical partition that extends radially from the hydraulic cylinder at an equal center angle divides the processing space into four or more processing chambers. A hub that moves up and down integrally with the piston rod of the hydraulic cylinder is rotatably fitted to the piston rod of the hydraulic cylinder.From the hub, the same number of arms as the processing chamber are extended conformally, and a basket is hung on the tip of the arm. The arm rotation drive mechanism for rotating the arm when the piston rod is in the raised position is attached to the ceiling partition of the main body. A door for loading and unloading the car into and out of the first processing chamber is provided with a drying means in the final processing chamber, and a cleaning means and a rinsing means are provided in the processing chamber between them as seen in the rotation direction of the arm. When a control means for the hydraulic cylinder and the arm rotation drive mechanism is provided, and the restriction means receives a start signal, the hydraulic cylinder pist rod is raised from the lowered position to the raised position, and then the arm rotation drive mechanism is driven to move the arm to the processing chamber. Then, the piston rod is lowered to the lowered position again, and then the piston rod is swung up and down in the vicinity of the lowered position for a certain time, and then stopped.

The arm rotation drive mechanism may be one that rotates a hub by a hydraulic motor and a gear ring, or one that pushes and rotates an arm by a hydraulic cylinder and a cam. It is desirable that the cleaning means and the rinsing means are provided with a temperature and level control system including a cleaning liquid circulation pump system including a filter, an ultrasonic generator, a heater, and a sensor, outside the cleaning tank.

The drying means preferably comprises a temperature control system including a sensor in addition to the hot air blower. It is desirable to attach a blower for blowing air to the work in the moving space above the processing chamber provided with the cleaning and rinsing means to drain the work. It is desirable that the car is rotatably hung on the arm, a vane plate is formed on the peripheral surface of the car, and the car is rotated by a blower to even out the water in the work in the car.

[0008]

[Function] When the door is opened and the car in which the unprocessed work is placed is hung on the arm in the lower position of the first processing chamber and the start switch of the device is turned on, the piston rod moves the car into which the unprocessed work is placed to the raised position. It then rises and then pivots above the second processing chamber, whereupon the piston rod lowers the car into the second processing chamber where it swings up and down for a period of time before stopping. At this time, the work is subjected to the cleaning action of the cleaning means. Then, when the door is opened and the next car is hung on the arm, the work that has been subjected to the cleaning action in the second processing chamber rises to the elevated position together with the car, and then rotates to the position above the third processing chamber, and then It descends into the third processing chamber, where it swings up and down for a certain period of time and then stops. At this time, the work is subjected to the cleaning or rinsing action of the cleaning means or the rinsing means of the third processing chamber. In this way, the basket containing the work moves to the next processing chamber where the work is processed. When the basket enters the final processing room, the work is dried by the drying means,
The process is complete. Since the first processing chamber is returned from the final processing chamber, the car containing the processed work is taken out from the door when the piston rod is stopped.

When the piston rod 21 is raised to the highest position shown by the chain line, the protrusion 29 of the arm 23 fits into the hole 30 of the arm rotation gear 26. The rotary gear 26 may be pushed and rotated by a hydraulic cylinder instead of being rotated by a hydraulic motor or an electric motor. The processing space 18 has four processing chambers 18a, 18b, 18c extending diagonally from a central cylinder 20.
Divide into 18d. Intermediate partition 15 is the second and third processing chamber 18
It is provided only on b and 18c and not on the first and fourth processing chambers 18a and 18d, and an opening 31 for passing the car 24 is provided at the center of the intermediate partition 15 on the second and third processing chambers.

As shown in FIGS. 2 and 4, the first processing chamber 18
Reference numeral a denotes a place where the car 24 accommodating the work enters and leaves the main body 10, and a table 32 on which the car 24 is placed is installed.
As shown in FIGS. 3 and 5, the second processing chamber 18b is a place where the work is washed with a water-based detergent, and a washing tank 33 in which the basket 24 is immersed is installed. The cleaning tank 33 has an ultrasonic generator 34 and a heater.
35 is provided, and the processing liquid is circulated through the filter. During cleaning, the piston rod 21 swings the car 24 up and down in the cleaning tank 33 as shown by the arrow. Air is blown onto the work in the car in the moving space 17 above the second processing chamber 18b. Install a blower 36 to drain the work.

As shown in FIGS. 2, 3 and 5, the fourth processing chamber 18d is a place for drying the work with hot air, and a hot air blower 38 for injecting hot air is attached to the car 24. During drying, the piston rod 21 swings the car 24 up and down as indicated by the arrow. As shown in FIGS. 6 and 7, the car 24 includes a car body made of stainless wire and a suspender 41 that suspends the car body, and a shaft portion 42 for rotatably bearing the end of the arm is provided at the center of the suspender 41. A vane plate 43 is provided around the peripheral surface of the car body 40, and the car body 40 is rotated by the air blown by the blower.

Next, the operation of the apparatus of the present invention will be described. The cleaning device can be operated by a program. Once activated, the piston rod 21 raises the arm 23 from the lowered position to the highest position. Therefore, the rotary gear 26
Rotates the arm 23 by 90 degrees. Then, the piston rod 21 lowers the arm 23 to the original position, and after the arm 23 is rocked up and down for a certain period of time in the lowered position, the piston rod automatically stops. This operation is repeated.

Since the door 12 can be opened and closed only while the cleaning device is stopped, the door 24 is opened to replace the car 24 of the arm 23 which has come to the first processing chamber 18a when the cleaning device is stopped. In other words, arm the basket 24 containing the work that has been cleaned.
Removed from 23 and armed the basket 24 with unprocessed work 23
Hanging. The unprocessed work stored in the basket 24 rises from the first processing chamber 18a to the moving space 17 above it, and then,
It rotates to the moving space above the second processing chamber 18b, then descends and is immersed in the cleaning liquid in the cleaning tank 33, and then rocks up and down for a certain period of time to receive an ultrasonic cleaning action and then stops. By the next activation, it rises to the moving space 17 above the second processing chamber 18b and receives the blowing action of the blower 36 there,
The basket 24 rotates and the work inside is drained uniformly.
Then, it moves to the moving space above the third processing chamber 18c, then descends and is immersed in the hot water washing tank 37, where it swings up and down within a certain period of time to receive a rinse action, and then stops. Then, it moves up to the moving space, where the basket 24 is rotated by the blowing action of the blower 36, and the work inside is drained evenly. Then, the car 24 pivotally moves into the moving space above the fourth processing chamber 18d, then descends and swings up and down for a certain period of time. Then, the work in the car is stopped after receiving the hot air blow of the hot air blower 38. At this time, the basket 24 is rotated by the hot air, and the work inside is uniformly dried. Then, the work in the basket 24 rises to the moving space, then returns to the top of the first processing chamber 18a again, and further descends, where it swings up and down for a certain period of time and stops. During this time, the car 24 raised by the hot air in the fourth processing chamber is cooled. Open the door 12 and arm the basket 24 containing the cleaned workpiece.
Remove from 23 and take out.

Stopping the piston rod and releasing the door 12
If the rise of the piston rod and the closing of the door 12 are interlocked with each other, all that is required is to replace the basket with the unprocessed work and the one with the unprocessed work. Less. Since all the processing is performed inside the main body 10, there is little risk that the workplace will be contaminated with washing liquid or the like. Further, since the respective processing chambers are isolated from each other, the optimum cleaning, rinsing and drying processes can be performed without being affected by the other processing chambers. Since the cleaning device can set the cleaning time according to the shape and size of the work, batches of various small-volume products can be efficiently carried out.

Since the above-mentioned embodiment comprises four processing chambers, the cleaning, rinsing and drying processing times are the same,
When the cleaning processing time is twice as long as the other processing time, as shown in FIG. 8, five processing chambers are provided and the second and third processing chambers 18 are provided.
b and 18c are washing baths 33, and fourth treatment chamber 18d is a washing bath 37,
The hot air blower 38 is installed in the fifth processing chamber 18c. At this time, the number of arms is 5, and the central angle, that is, the rotation angle for one rotation is 72 degrees. Although not shown, if the time required for cleaning is three times that of other processes, or if the time required for cleaning and rinsing is twice the drying time, then six processing chambers are provided,
The number of arms is 6, and the rotation angle is 60 degrees.

The washing liquid in the washing tank and the hot water washing tank is circulated by a pump, and dust is removed by a filter on the way. As shown in FIG. 9, the nozzle 45 for ejecting the circulating liquid to the washing tank 33 or the hot water washing tank is used.
If the jet flow from the nozzle is provided and the car 24 is rotated in the direction of the arrow in the tank toward the vane plate 43 of the car 24 as indicated by the arrow, the cleaning effect of the work can be enhanced. As shown in FIGS. 10 and 11, the moving space 17 can be partitioned according to the processing chamber therebelow. In this case the arm
A plate 50 that is rotatable around the piston rod 21 is provided above 23. The outer periphery of the plate 50 is a basket when viewed from above.
It almost coincides with the outer circumference of the rotation trajectory of 24. A concave portion 46 or a convex portion is formed on the lower surface of the plate 50, and a convex portion 47 or a concave portion is formed above the arm 23. As shown by the chain line in FIG. 10, when the arm 23 rises, the projection 29 of the arm 23 fits into the opening 30 of the arm rotation gear 26, and the projection 47 fits into the recess 46 of the plate 50. At this time, the stopper 48 is fixed to the vertical inner surface of the main body 10. When the arm 23 rises, the arm 23 is initially independent but rises together with the plate 50 halfway.

As shown in FIG. 11, the plate 50 and the intermediate partition 15 or the vertical partition 19 are provided with as many vertical moving partitions 51 and fixed partitions 52 as there are processing chambers. Moving partition 51 and fixed partition
The height of 52 is approximately equal to the distance from the intermediate partition 15 to the stopper 48. The moving partition 51 is substantially equal to the radial cross section of the rotation trajectory of the car 24. When the plate 50 rises, the plate 50 loosely fits in the arm rotation gear 26. Arm rotation gear 26
Is rotatably supported by the guide 25, and the guide 25 is partitioned by the ceiling.
Fix at 14. A motor 27 is attached to the ceiling partition 14, and a gear 28 fixed to the output shaft of the motor is engaged with the arm rotation gear 26. The gears 26 and 28 are bevel gear rings,
The motor 27 rotates the arm 23 by a predetermined angle via a bevel gear ring. When the arm 23 descends, the plate is initially
Although 50 also descends, when the plate 50 contacts the stopper 48, it separates from the arm 23. Seen from above, each movable and fixed partition 51, 52 coincides with each vertical partition 19 which partitions the processing chamber. When the moving space 17 is partitioned by the movable and fixed partitions 51, 52 according to the processing chambers below it, each processing chamber is more reliably separated and independent, so that each processing chamber is affected by other processing chambers. Optimal cleaning, rinsing and drying treatments can be carried out.
