Description

[Detailed explanation of the invention] [Purpose of the invention] (Field of industrial use) This invention is applicable to electronic parts, lenses, ceramics, ICs, etc.
The present invention relates to a cleaning device that uses ultrasonic cleaning to clean objects such as substrates, precision parts, automobile parts, and mechanical parts.

(Prior Art) As shown in FIG. 2, in a conventional cleaning device, a cleaning basket 1 containing objects to be cleaned is carried in by a carry-in conveyor 2, and the cleaning basket 1 is placed under a transportation reciprocating device 3.
Washing is carried out by placing the washing basket 1 on each pedestal 7 which is installed in a washing tank 6 having an ultrasonic vibrator 5 and connected to a swinging cylinder (not shown) using a hanger 4 that holds the washing basket 1. After washing, transportation reciprocating device 3
The cleaning basket 1 is conveyed to the tanks one after another and the cleaning conveyance is repeated, and the cleaning basket 1 is transferred to the steam tank 8 as the final tank.
It is configured so that the objects to be cleaned inside are steam-dried and carried out by a carrying-out conveyor 9. In this case, there are four tanks including the steam tank 8, and the transporting and reciprocating device 3 has five hangers 4 installed below to sequentially transport the washing baskets 1. In the initial state, the position of the hanger 4 is as shown in the figure, and here, the hanger 4 descends, rises while holding the washing basket 1, and then moves one stroke to the right.
The conveying and reciprocating device 3 reciprocates the hanger 4 so that it descends again to release the washing basket 1 and place it on the pedestal 7, and then rises again and returns one stroke to the left to return to the initial state.

In such a cleaning device, the number of cleaning tanks 6 differs depending on the type of the object to be cleaned, and if the number of hangers 4 was set to correspond to the number of tanks as described above, it would be difficult to install each hanger 4 for each cleaning device. It is necessary to change the specifications of the transport reciprocating device 3, which is time consuming and expensive because the number of hangers 4 is large. Furthermore, if the distances between the tanks are different, the stroke length of the hanger will be different, making the reciprocating movement more complicated. Furthermore, if there are a large number of hangers as in the conventional example, cleaning can be done efficiently and in a short time when a large number of items are to be cleaned, but when there are relatively few items to be cleaned, cleaning basket 1 is used. There was also the problem that the hanger 4 that was not clamped also moved, resulting in extremely uneconomical results.

As a solution to this problem, JP-A-58-
Publication No. 40183 discloses a method in which a support shaft is provided in a frame housing a cleaning tank along the cleaning tank, a transport head is movably provided along this support shaft, and a basket can be suspended from the transport head. A degreasing cleaning device provided with a lifting rod has been proposed.

(Problem to be solved by the invention) In the device using the above-mentioned conveying head, the conveying head moves above the cleaning tank along the spindle, and the elevator rod on which the car is suspended moves up and down to clean the lower end side. Items to be cleaned inside the basket can be cleaned by placing them in the tank.
The transport head for transporting the basket has a simplified structure, eliminates the need for complicated reciprocating movements, and can be driven efficiently even when there are few items to be cleaned. However, in order to perform cleaning using the above-mentioned device, an operator must place a basket from the outside into a mounting tank provided within the frame, and after cleaning, the worker must place the basket carried by a transport head into a retrieval tank provided within the frame. It has to be taken out from the tank, and the loading and unloading work by these workers is required, making it difficult to automate the entire cleaning process between loading and unloading.

Therefore, the present invention was developed based on the above problems, and aims to automate the cleaning process from loading to unloading, can be used regardless of the number of tanks, and has a simple structure and can be used economically. The purpose of the present invention is to provide a cleaning device that is easy to use.

[Structure of the invention] (Means for solving the problem) The present invention includes a plurality of cleaning tanks arranged in parallel inside an outer casing, and objects to be cleaned stored in a washing basket are brought in from the carry-in side of the outer casing. In the cleaning device that cleans in the cleaning tank and carries out the cleaning from the carry-out side, there is a transport rail installed above the plurality of cleaning tanks, and the cleaning basket is sequentially movable to each of the cleaning tank positions along the transport rail. a lifting bar provided on the transporting reciprocating device and capable of being raised and lowered by a lifting device; a hanger provided at the lower end of the lifting bar from which the washing basket can be hung; a carry-in port located at the lower side of the outer casing; a carry-in conveyor located at the bottom of the carry-in port and disposed substantially parallel to the carry-in port; and a carry-in conveyor provided at the carry-out side of the outer casing. The conveyor includes a carry-out port, and a carry-out conveyor inserted through the carry-out port and disposed at the lower part of the carry-out side of the carry-out rail.

(Function) The washing basket carried to the lower part of the carry-in entrance by the carry-in conveyor is lifted up by a hanger, and is sequentially moved to each washing tank by a transportation reciprocating device to be cleaned.After conveying the washing basket through the carry-in mouth, the hanger carries it out. The washing basket is placed on the conveyor, and the washing basket is carried outside, and the hanger is returned to the carry-in position by the conveying and reciprocating device to hoist the next washing basket.

(Example) Hereinafter, an example of the present invention will be described in detail based on the drawings. In FIG. 1, reference numeral 11 denotes a cleaning basket that stores objects 12 to be cleaned. 13 is ultrasonic cleaning device 1
4, and is provided with a carry-in port 16 through which the washing basket 11 is carried in by a carry-in conveyor 15 and a carry-in port 18 through which it is carried out. 19 is the ultrasonic transducer 2
0 on the lower surface and is an ultrasonic hot bath cleaning tank filled with a cleaning liquid 21. The cleaning liquid 21 is appropriately heated by a heater 22 and the ultrasonic vibrator 20 is excited to clean the object 12 to be cleaned. 23 is a cold bath filled with cleaning liquid 21, and the object 12 to be cleaned is cleaned by immersing it in the cleaning liquid 21 cooled to an appropriate temperature by a cooling pipe (not shown). 24 is a steam tank, in which cleaning liquid 21 heated by a heater 25 disposed inside is evaporated, and the object 12 to be cleaned is cleaned and dried with the vapor. Reference numeral 26 denotes a cooling zone arranged above the ultrasonic hot bath cleaning tank 19, cold bath 23, steam tank 24, etc., in which the vaporized gas of the cleaning liquid 21 is liquefied through a cooling pipe 27, dropped, and collected. be.

28 is a transportation reciprocating device for transporting the cleaning basket 11 to each cleaning tank, and includes a transportation rail 30 horizontally installed on legs 29 fixed to the inside of the outer casing 13 by bolts or welding, etc. It is constituted by a single hanger 33 which is provided to be reciprocatable in the horizontal direction on the transport rail 30, fixed to one end of a lift bar 31, and provided to be movable up and down by a lift device 32. This hanger 33 can clamp and suspend the washing basket 11. Also,
As clearly shown in FIG.
The carry-in port 16 is provided at the lower part of the carry-in side of the transport rail 30, and the carry-in conveyor 15 is arranged below the carry-in port 16 substantially parallel to the carry-in port 16. 34 is an ultrasonic oscillator that excites the ultrasonic transducer 20;
5 is an operation panel for performing various operations. The top surface of the cooling zone 26 is covered with an inner lid made of acrylic resin, except for the opening that allows the cleaning basket 11 to be taken in and out.
1 is closed except for the movable opening.

The operation of the present invention configured as above will be described in detail below. First, the cleaning basket 11 containing the items to be cleaned 12 is clamped between the hangers 33 from the top of the carry-in conveyor 15, carried into the outer casing 13 through the carry-in port 16, held by the hangers 33, and pulled upward. and is located above the ultrasonic hot bath cleaning tank 19 along the horizontal rail 30. And washing basket 11
is lowered by the lifting bar 31 and the lifting device 32,
While being held between the hangers 33, it is immersed in the cleaning liquid 21 and subjected to ultrasonic cleaning. Thereafter, the cleaning basket 11 rises, moves above the cold bath 23 along the horizontal rail 30, and descends, and is immersed in the cleaning liquid 21 of the cold bath 23 to be cleaned. And finally, washing basket 1
1 rises and moves along the horizontal rail 30 to the steam tank 24
After moving upward and descending, being steam-cleaned and dried in the steam tank 24, it is placed on the carry-out conveyor 17, and carried out to the outside of the outer casing 13 by the carry-out conveyor 17. Thereafter, the hanger 33 returns to the carry-in conveyor 15, clamps the next washing basket 11, and performs the same operation.

In this way, the conveying reciprocating device 28 has one hanger 33 and can handle one washing basket 1 carried in.
1 is sequentially conveyed to each cleaning tank, subjected to a series of cleaning and drying, and conveyed to the carry-out conveyor 17,
It is configured to return to the carry-in conveyor 15 again, and a series of operations from carry-in to carry-out is performed continuously, so the structure and operation are simpler than conventional ones equipped with multiple hangers. . Furthermore, the cleaning time for the object to be cleaned 12 placed in the cleaning tank can be changed to an appropriate time for each tank, allowing for very efficient use. Incidentally, since conventional products with multiple hangers can only be transported at regular intervals, this time was set as the maximum cleaning time. Furthermore, although this type of cleaning device often differs in the number of cleaning tanks and the distance between the cleaning tanks, in the case of the present invention, there is only one hanger 33, so the setting of the vertical movement position of the hanger 33 can be changed. It can be easily attached to various cleaning devices by simply doing the following. In addition, if you want to make an existing manual cleaning device automatic, you can attach the legs 29 to the existing outer casing with bolts or welding, and set a program so that the hanger 33 moves up and down in accordance with the cleaning tank. It can be attached to any cleaning equipment, and existing manual cleaning equipment can be easily converted to an automatic one. Furthermore, since there is only one hanger 33, even when there are few items 12 to be cleaned,
The transportation reciprocating device 14 can be operated economically with less waste.

In addition, this type of cleaning equipment uses various cleaning liquids, and requires atmosphere control and temperature control of the cleaning tank, such as cooling after cleaning and heating for drying. Since the carry-in conveyor 15 is arranged almost in parallel and does not pass through the carry-in port 16, no air flow is generated at the carry-in port 16 due to the drive of the carry-in conveyor 15, and the washing basket 11 on the carry-in conveyor 16 is simply moved. Since the hanger 33 only passes through the loading port 16 during lifting, the atmosphere inside the outer casing 13 can be maintained in a good condition.

Above, one embodiment of the present invention has been described in detail.
It can be modified as appropriate within the scope of the gist of the present invention. For example, in the above embodiment, the washing basket 11 is attached to the hanger 33.
Although a configuration has been described in detail in which the washing basket 11 is washed while being suspended, the hanger 33 may separate the washing basket 11 from each washing tank for washing, and after washing, the hanger 33 may clamp the washing basket 11 again and move it to the next tank. This allows the washing baskets 11 to be sent one after another, making it possible to wash a plurality of washing baskets 11 at the same time, and also facilitating rotational washing. Further, the number of cleaning tanks is not limited to three. Furthermore, a cylinder or the like may be used as the lifting device 32 for lifting and lowering the hanger 33.

[Effect of the invention] A plurality of cleaning tanks are arranged in parallel in an outer casing, and objects to be cleaned stored in a washing basket are carried in from the carry-in side of the outer casing, cleaned by the washing tank, and carried out from the carry-out side. In the cleaning device, there is provided a transport rail constructed above the plurality of cleaning tanks, a transport reciprocating device capable of sequentially moving the cleaning basket to each of the cleaning tank positions along the transport rail, and the transport reciprocating device. a lifting bar provided on the device and capable of being raised and lowered by a lifting device;
