Description

Detailed Description of the Invention (Technical Field) The present invention relates to a device suitable for cleaning processing jigs used for fixing a workpiece after finishing processing the workpiece, and furthermore, relates to a device suitable for cleaning a processing jig used for fixing the workpiece, and furthermore, to a device suitable for cleaning the processing jig used for fixing the workpiece after finishing the processing of the workpiece. The present invention relates to a device suitable for organically incorporating a heating device into a cleaning device and incorporating it online after performing a heating process for one hour.

(Technology) Glass or general processing materials can be bonded with a heat-melting mixed adhesive (for example, one with a melting point of approximately 30°C to 170°C).
The processing process is well known, in which the glass and processing materials are removed after the glass is glued to a sword tool jig and polished and cut in this state.

Even after the glass and processing materials are removed, the jig still has impurities attached to it, including adhesive substances and workpieces from polishing or cutting, so the jig is cleaned in a short bath.

Furthermore, when bonding the work to the jig again, the bonding work is performed after heating.

Conventionally, a problem when cleaning jigs is that inorganic stains, especially silicate, nium oxide, cerium oxide, carbon, etc., adhering to the jigs are significant and cannot be removed by cleaning with a solvent alone. Even with water-soluble cleaning, in order to efficiently clean inorganic impurities, the temperature of the liquid must be approximately 70 to 80 degrees Celsius.
It is desirable to apply ultrasonic waves at the same time as the temperature increases, but the normally used magnetostrictive ferrite vibrators often break due to heat, making it difficult to obtain an efficient ultrasonic cleaning effect.
In terms of heating, processing jigs were heated using gas equipment, but this required heating time of 20 minutes or more, making it difficult to incorporate into the processing line.

On the other hand, when cleaning is repeated by sequentially immersing the product in multiple cleaning tanks,
#Solid particles from the previous cleaning process may adhere to processing jigs and jig baskets and be carried into the next process, reducing efficiency. For example, the surfactant contained in the water-soluble emulsion 17 solution may dissolve in the ethylene-based solvent, and the surfactant may make the water opaque, lowering the temperature of the solvent. Ran.

(Objective) The object of the present invention is to enhance the cleaning effect, and to shorten the heating time when performing knife heat after the cleaning process is completed.

Another purpose is to prevent the cleaning liquid from adhering to the jig or the jig basket and moving to the subsequent cleaning tank, or to make it possible to separate the cleaning liquid that has moved.

Still another purpose is to increase the temperature of the liquid by using the heat from the furnace for heating the jig for cleaning and immersion, thereby increasing the cleaning effect.

In order to achieve the above objective, a plurality of cleaning tanks were arranged in order according to the transport DM, a heating length was installed, a transport device was installed to make the target cuttings run independently, and a stage immediately before the heating device was installed. A device will be installed to increase the temperature of the liquid in the cleaning tank. At least one liquid in the cleaning tank is heated by a heating device or heated to separate water-soluble solvents from organic solvents.
fcit, or a mechanism for tilting the jig or jig cage to improve liquid drainage.

(Example) Next, the present invention will be described in detail using the drawings from FIG. 1 onwards. In Fig. 1, 1 is a belt conveyor, and Z is used to carry in objects 10 such as jigs or jig baskets that have been processed in the previous process.
iA has a meaning. 1. is a motor for driving this belt conveyor. 2 is a chain conveyor, and 2° is a hanging claw that grips the object 10 at position A. FIG. 2(A) shows the object 10, while FIG. 2(B) shows this object 10.
The figure depicts the claw 2 gripping. That is, the two claws grip the object 10 at an angle of 15°4!4°, and thereafter convey it in this state. The reason why objects such as jigs and jig baskets are held at an angle is that they have many horizontal components and have the disadvantage that they are difficult to drain.

Returning to FIG. 1, reference numeral 3 denotes the first cleaning solvent tank, which is filled with an ethylene-based shoulder bath additive, and is heated by the heat of the 7IO heating furnace as described later. 4 is a second cleaning solvent tank filled with a water 66 emulsion type solvent. 5 is an ultra-old wave @ vibrator for applying 10 fζ ultrasonic waves to the target object through a solvent, and uses, for example, an electrostrictive type lead zirconium titanate vibrator that is similar to heat, and a heating device (not shown) to generate water-soluble By heating the emulsion solvent to 70° C. to 80° C. and applying ultrasonic waves in this state, removal of abrasive materials, inorganic particulate matter, or stale materials can be promoted.

Reference numeral 6 denotes a third cleaning and decomposition tank, in which an ethylene-based organic solvent such as tetrachlorethylene is mixed.

This solvent tank 6 is equipped with a device for separating the solvent from the water-soluble emulsion transported from the previous solvent tank, the configuration of which will be described later. However, the important point here is this bath salt tank 6.
The solvent that is circulated is heated to about 100υ to 110'O, and the heat of this solvent preheats the object. The preheating temperature is determined based on the boiling point of the solvent, which is 120° C. in the case of teto2chlorethylene, and the jig heating temperature.

The path of the chain conveyor 2 is determined so that the object is immersed in the solvent at positions 3, 4, and 6, and in reality, the object is conveyed multiple times in a timely manner.◎7 is a heat-resistant conveyor, driven by a 7-volt drive source, and has a
The object conveyed by the chain conveyor 2 is received and conveyed through the heating furnace 8. The heating furnace 8 is equipped with upper and lower infrared heaters 8a and 8b, and further heats the object that has already been dried and heated to 100°C to 110°C in about 4 to 5 minutes.
Let it reach around 0℃. The object is conveyed horizontally on the heating conveyor 7. Rank r! At tC, the object is again
It is gripped by a chain conveyor 2 and transferred to a belt conveyor 9 for carrying out at a certain position. The belt conveyor 9 for carrying out is brought to a desired temperature and then carried to the work area for the next process.

Q. Reference numeral 11 is a drive cylinder for accelerating liquid drainage, and the cylinder 11 has a function of moving a pressure bar: 12. When the object is pulled up from the solvent surface by the chain conveyor 2, the suppression bar 12, for example, presses a part of the cage to tilt it to a 351 angle, as shown in FIG. Make sure that the solvent that has accumulated in the tank is washed away.

Next, an apparatus for heating the solvent in the first cleaning solvent bowl 3 with the heat of the heating furnace 8 will be explained using FIGS. 3 and 4.

In Figure 3, is the heat of heating furnace 8 used for exhaust? (The heat is exhausted through 15. 16 is a thermal duct connected to the exhaust damper 15, and is connected to the exhaust heat exchange device 17 in another layer. 18 is a medium between the solvent tank 3 and the exhaust heat exchange device! 117. This is a pump for circulation. 19 is a 77 pump for exhaust, which discharges unnecessary heat to the outside world.

In FIG. 4 depicting the inside of the exhaust heat exchange device 17, 20 is a housing for a heat insulating material, 21 is a heat exchange tube, and the housing 20
It is placed with a cotton line drawn inside.

22 is a hot air separation plate, which appropriately partitions 1/g 20 to form a hot surface.

Therefore, hot air from the heating furnace 8 is guided into the housing 20 through the heating duct 16. The pump 18 is the solvent tank 3
The four agents are sent to the heat exchange tube 21, the solvent is heated, and the F
' Returned to S agent tank 3. For example, the heating furnace 17 is
When the temperature was set to 100°C and the four liquids of tetrachlorethylene 7501 were heated using an exhaust heat exchanger, a temperature of 100°C was obtained in about 30 minutes.

Returning to FIG. 1, 25 is a solvent heating device that can use a separate heater or the heat exchanger described above.

Reference numeral 26 is a closed water and steam dispensing tank, the details of which are shown in Figure 5. 27 is a storage tank for water and steam, 28 is a pump for circulating the bath medium, and 29 is a tank for adding water absorbing and separating agent.

In FIG. 5, 30 is a solvent return port, through which the solvent from the solvent 14I6 is sent. 31a, 31b, and 31c are divided tanks, and as indicated by the arrows, the solvent is supplied to the first divided tank 31a.
The water enters the second divided tank 31b from the bottom of the tank, then overflows the second divided tank 31b and accumulates in the third divided tank 31c. A steam recovery pipe 32 opens at the ceiling of the first divided tank 31a and is connected to the reduced pressure aggregation tank 33 via a control valve with additional teeth. The reduced pressure coagulation tank 33 functions to return steam to water, and the water is stored in the storage tank 27. 34 is a water injection pipe, and the second one is located below the return port 30.
It opens at a position slightly higher than the wall of the third divided tank 31c1beaic, and connects the storage tank 2 through an appropriate control valve.
Leads to 7.

Since the solvent poured from the return port 30 into the first divided sand 31a, for example, tetrachlorethylene, is heated to 120°C, the moisture either becomes steam and flows into the steam recovery pipe 32, or becomes boiling water and is heated to 120°C. It is separated from the chlorethylene, accumulates on the surface, and is collected through the drain pipe 34 into the storage tank 27. The solvent from which the dried water has been separated is stored in the first divided tank 31a.
From there, the second divided tank 31bf enters, and then the third divided tank 31c enters.
The liquid is stored in. The circulation pump 28 circulates the solvent in the third divided tank 31c to the third cleaning bath via the tank 29 (Fig. 1) for attaching a water absorption and separation agent.◇ The configuration is as above. Therefore, the object 1o placed on the feeding belt conveyor 2 in FIG. discovered and immersed in liquid;
Adhesive etc. are cleaned.

Next, it is immersed in a water-soluble emulsion type second cleaning solution 44, at which time ultrasonic waves are applied to mainly clean inorganic substances. When the S-system cleaning is completed, it is immersed in the third cleaning tank 6 for final cleaning. At this time, the temperature of the ethylene-based fiA solvent is maintained at 120°C, and the temperature of the object is heated to approximately 100'Q to 110°C.

The water bathing emuldigon liquid brought in from the front tank is effectively separated in the water separation tank 26, and part of it is stored as water and the other part is collected as steam [27].

On the other hand, if cIT is dissolved in a very small amount of water in the surfactant, there will be no problem with the temperature distribution of the object 10, but if a large amount is dissolved in the surfactant, a water absorbing and separating agent is added in tank 29 for dehydration. Afterwards, return it to the cleaning tank. In addition, in order to minimize the amount of liquid brought into the six tanks, the claws of the conveyor were held at an inclination of about 15 degrees so that the object could be tilted. In addition, draining device 111.1
2 is provided, and the object is further tilted by 15° to 20° using the bar 12 to drain the liquid.

The object dried and heated to 100°C to 110°C in the third cleaning tank 6 is set on the heating conveyor 7, and heated to 170°C for about 4 to 5 minutes by the upper and lower infrared heaters 8a and 8b in the heating furnace 8.
It is heated to around ℃. The heated object 10 is conveyed again from the fixed position at the exit of the heating conveyor, set on the exit completion conveyor 9, and conveyed.

(Effects) According to the present invention as described above, since everything from cleaning to heating the blade is carried out consistently, there is an effect that the next process can be started in an extremely short time. Further, cleaning is carried out extremely efficiently, and since the temperature of the cleaning liquid can be determined by using the exhaust heat of the heating device, there is an advantage that not only the cost for heating can be reduced, but also the exhaust heat treatment facility can be used only for residual heat treatment.

Furthermore, since the movement of liquid between the plurality of liquid tanks is suppressed as much as possible, the cleaning effect is maintained at a high level, and even if water is mixed into the organic solvent, it can be effectively separated.
