Description

The present invention relates to a processing liquid agent diluting device for diluting a processing liquid agent supplied to a processing machine as a mold release agent for forging or a coolant liquid for lathe processing.

Conventionally, processing liquids such as mold release agents and coolants have been used in processing machines that perform metal plastic working such as hot forging and metal processing such as cutting and grinding. In general, such a liquid for processing often uses an emulsion type in which a water-soluble oil (hereinafter referred to as "stock solution") is diluted with water. The above stock solution must be diluted with water to a concentration determined by water before use.

The processing liquid agent is supplied to the processing machine after being stored in the storage tank, the residue used as the mold release agent in the processing machine is collected, the solid content is separated, and the liquid is returned to the storage tank to be processed again. Supply to the machine. The above-mentioned processing liquid is consumed by taking out or evaporating while being circulated and used as described above.

The amount of processing liquid to be circulated must be controlled within an appropriate range. Therefore, for the amount of the processing liquid that has been consumed and reduced, a new processing liquid prepared by diluting a new stock solution with water to a predetermined concentration is adjusted and added to the storage tank. At this time, it is necessary to control the concentration of the processing liquid to be circulated within an appropriate range.

When diluting the stock solution, the stock solution is weighed and water is introduced at a predetermined ratio to the weighed stock solution.

Recently, in order to improve mold releasability and machinability, a stock solution containing a solid lubricant such as graphite powder may be used.

However, it is difficult to measure the undiluted solution containing such powder using various flow meters because the powder sticks to the undiluted solution and erroneously detects it. Therefore, when a flow meter is used for weighing, it is not possible to dilute at an accurate ratio, and it is not possible to properly manage the processing liquid.

Therefore, for a stock solution containing a solid lubricant such as graphite powder, it is necessary to measure the stock solution by means other than a flow meter.

The applicant is aware of Patent Document 1 below as prior art documents relating to the supply of processing liquids such as coolants.

However, when the undiluted solution containing powder such as a solid lubricant is weighed in this cutting oil supply device, accurate measurement cannot be performed and the processing liquid cannot be controlled at an accurate dilution concentration. That is, since the undiluted solution containing powder has high viscosity and poor fluidity, many undiluted solutions adhere to the inner surface of the measuring cup and remain after the measuring undiluted solution is charged in the measuring cup. Further, if the undiluted solution is left on the inner surface of the measuring cup until the next measurement, the attached undiluted solution dries and sticks, and the next measurement becomes more inaccurate. That is, the apparatus of Patent Document 1 cannot dilute the stock solution at an accurate ratio, and cannot properly manage the processing liquid.
The undiluted solution, which is premised on dilution, generally has a high viscosity, and when weighed with a measuring cup, the undiluted solution tends to remain on the inner surface of the undiluted solution.

Further, the apparatus of Patent Document 1 adjusts the amount of inclination of the measuring cup with a spring, turns off the solute input valve based on the amount of inclination, and measures the amount of solute input. That is, if the spring does not operate normally, accurate weighing cannot be performed. For example, if a highly viscous solute adheres to the spring and dust further adheres to it and sticks to it, the spring will not operate normally, accurate weighing will not be possible, and the stock solution cannot be diluted at an accurate ratio. is there.

It is a block diagram which shows one Embodiment of the dilution apparatus of the liquid agent for processing of this invention.

FIG. 1 is a configuration diagram showing an embodiment of a diluting device for a processing liquid agent of the present invention.

[Processing liquid]
The processing liquid agent targeted by this embodiment is obtained by diluting a stock solution with water. Examples of the processing liquid include a mold release agent used for hot forging and a coolant for cutting. The undiluted solution includes an emulsion type, a soluble type, a solution type and the like, all of which can be applied to the present embodiment.

As the stock solution, a mixture of solid lubricant powders such as graphite powder and molybdenum disulfide powder can be used.

The undiluted solution and water are mixed at a predetermined mixing ratio suitable for the product, application, environment, etc., and are used as a mold release agent or a coolant solution in the processing machine 100.

〔overall structure〕
The processing liquid agent diluting device of the present embodiment includes a storage tank 10, a measuring container 20, a liquid amount sensor 30, a charging means 40, and a cleaning means 50.

The storage tank 10 stores a processing liquid obtained by diluting the stock solution with water.
The measuring container 20 measures the undiluted solution supplied from the undiluted solution supply path 61.
The liquid amount sensor 30 detects the amount of the undiluted solution supplied into the measuring container 20.
When the liquid amount sensor 30 detects that the undiluted solution in the measuring container 20 has reached a predetermined amount, the charging means 40 charges the undiluted solution in the measuring container 20 into the storage tank.
The cleaning means 50 cleans the inner surface of the measuring container 20 by spraying a processing liquid or water during and after charging by the charging means 40.

In the above apparatus, the processing liquid agent stored in the storage tank 10 is supplied to the processing machine 100 through the liquid agent supply path 1. The processing liquid used in the processing machine 100 is collected in the recovery tank 2. The processing liquid recovered in the recovery tank 2 is returned to the storage tank 10 by the reflux path 3 and recycled.

During recycling, the processing liquid is consumed and reduced by taking out and evaporating. When the amount of processing liquid is reduced, a new processing liquid is added by newly supplying the undiluted solution and water for diluting it.

The new processing liquid agent is added by adding the undiluted solution stored in the undiluted solution can 60 and the water for dilution to the storage tank 10 by the additional unit 70.

In the additional unit 70, the undiluted solution is supplied from the undiluted solution supply path 61 to the measuring container 20, a predetermined amount is weighed, and the undiluted solution is charged from the measuring container 20 into the storage tank 10. The stock solution is added by inclining the measuring container 20. The water to be diluted is supplied by supplying a predetermined amount from the water supply path 51. At this time, by spraying water to be supplied to the inner surface of the inclined measuring container 20, the undiluted solution adhering to the inner surface of the measuring container 20 is washed away and put into the storage tank 10.

[Storage tank]
The storage tank 10 includes a dirty tank 11 and a clean tank 12. The dirty tank 11 and the clean tank 12 are separated by a partition wall 13A. The partition wall 13A is set to a height at which the clean liquid in the clean tank 12 overflows into the dirty tank 11.

The dirty tank 11 stores the dirty liquid recovered from the processing machine.

The dirty tank 11 has a conveyor area 11A provided with a discharge conveyor 14A for discharging turbid substances such as sludge, and a storage area 11B for storing a secondary dirty liquid in which turbid substances are discharged. The conveyor area 11A and the storage area 11B are separated by a partition wall 13B. The partition wall 13B is set to a height at which the secondary dirty liquid overflows from the conveyor area 11A to the storage area 11B.

The discharge conveyor 14A discharges a relatively large amount of turbid matter from the dirty liquid. At the tip of the discharge conveyor 14A, a liquid removal conveyor 14B for removing the discharged turbid matter is arranged. In this example, a scraping type conveyor is applied to the discharge conveyor 14A, and a screw condenser is applied to the liquid removal conveyor 14B. The turbid material deflated by the deflated conveyor 14B is put into the pit 4. Reference numeral 4A is a pit liquid level gauge 4A provided in the pit 4. The liquid separated from the turbidity is returned to the conveyor area 11A.

The conveyor area 11A is provided with a constant liquid level gauge 14C and an emergency liquid level gauge 14D. The constant liquid level gauge 14C measures the liquid level in the conveyor area 11A during operation. The emergency liquid level gauge 14D detects that the liquid level in the conveyor area 11A has risen abnormally. When the liquid level in the conveyor area 11A rises abnormally, the operation of the apparatus is controlled to be stopped.

The storage area 11B is provided with a liquid feed pump 15A that sends the secondary dirty liquid to the clean tank 12. The secondary dirty liquid is sent to the clean tank 12 through the liquid feed passage 15B by the liquid feed pump 15A. The liquid supply passage 15B is provided with a cyclone filter 15C for removing relatively small turbid substances remaining in the secondary dirty liquid. The powder such as the solid lubricant dispersed in the processing liquid is not removed by the cyclone filter 15C, and the clean liquid is in a state where the powder is mixed.

The clean tank 12 stores a clean liquid obtained by removing turbid substances such as sludge from the dirty liquid.

In the clean tank 12, the stock solution and water for dilution are added from the additional unit 70 to the stored clean liquid.

The clean tank 12 is provided with a stirring device 16A, a liquid level gauge 16B, and a concentration sensor 16C.

The stirring device 16A stirs the stored clean liquid and the added stock solution and water when the stock solution and water for dilution are added from the additional unit 70.
The liquid level gauge 16B detects and monitors the liquid level of the clean liquid stored in the clean tank 12.
The concentration sensor 16C detects the concentration of the clean liquid stored in the clean tank 12.

A liquid agent supply path 1 having a supply pump 1A is connected to the clean tank 12. A clean liquid (processing liquid agent) is supplied to the processing machine 100 through the liquid agent supply path 1. A branch path 1B is provided in the liquid agent supply path 1. The tip of the branch path 1B opens to the upper part of the discharge conveyor 14A of the dirty tank 11. As a result, the cleaning liquid is sprayed on the surface of the discharge conveyor 14A for cleaning.

The processing liquid used as a release agent or coolant in the processing machine 100 becomes a dirty liquid and is recovered in the recovery tank 2. Reference numeral 2A is a liquid level gauge 2A. The dirty liquid recovered in the recovery tank 2 is returned to the storage tank 10 through the return passage 3 having the pump 3A. The tip of the return path 3 is arranged in the conveyor area 11A of the dirty tank 11. That is, the refluxed dirty liquid is discharged to the conveyor area 11A.

[Additional unit]
The additional unit 70 includes a measuring container 20, a liquid amount sensor 30, a charging means 40, and a cleaning means 50. The additional unit 70 adds a new processing liquid agent to the clean tank 12 by adding the undiluted solution stored in the undiluted solution can 60 and the water for dilution to the storage tank 10.

[Measuring container]
The stock solution stored in the stock solution can 60 is supplied to the measuring container 20, and the stock solution to be added to the clean tank 12 is weighed. The measuring container 20 is a deep excavator-shaped container. When a predetermined amount of the undiluted solution is filled, the undiluted solution inside is tilted forward and charged into the clean tank 12.

The undiluted solution can 60 is a drum can in which the undiluted solution is stored. The stock solution inside is pumped up by the pump 61A and supplied to the measuring container 20 by the stock solution supply path 61. The undiluted solution in the undiluted solution can 60 is agitated by the stirrer 62, and the liquid level is detected by the liquid level meter 63.

[Liquid level sensor]
The liquid amount sensor 30 detects the amount of the undiluted solution supplied into the measuring container 20. As the liquid level sensor 30, a liquid level sensor that detects the liquid level of the undiluted solution supplied into the measuring container 20 can be used. An optical sensor can be used for the liquid amount sensor 30, and the liquid amount of the undiluted solution supplied into the measuring container 20 is detected from a position slightly away from the measuring container 20. This prevents interference between the measuring container 20 and the liquid amount sensor 30 when the measuring container 20 repeatedly tilts and returns. When the liquid amount sensor 30 detects that the measuring container 20 is filled with a predetermined amount of undiluted solution, the pump 61A is controlled to be stopped.

[Input means]
The charging means 40 charges the stock solution in the measuring container 20 into the storage tank 10 by tilting the measuring container 20. That is, when the measuring container 20 is filled with a predetermined amount of the undiluted solution, the excavator-shaped measuring container 20 is tilted forward and the internal undiluted solution is put into the clean tank 12.

In this example, the charging means 40 includes a support shaft 41 and a drive cylinder 42. The support shaft 41 supports the measuring container 20 so that it can rotate back and forth. The drive cylinder 42 drives the measuring container 20 supported by the support shaft 41 so as to rotate back and forth.

In the charging means 40, when the liquid amount sensor 30 detects that the measuring container 20 is filled with a predetermined amount of undiluted solution, the driving cylinder 42 drives the excavator-shaped measuring container 20 so as to incline forward. The undiluted solution inside is put into the clean tank 12. When the charging is completed, the drive cylinder 42 drives the measuring container 20 to rotate backward, and returns the measuring container 20 to the original position.

[Cleaning means]
The cleaning means 50 includes a water supply path 51 and a cleaning nozzle 53.
The cleaning means 50 sprays the processing liquid or water on the inner surface of the measuring container 20 from the time when the stock solution is charged by the charging means 40 to after the stock solution is charged. As a result, the inner surface of the measuring container 20 is washed, the undiluted solution adhering to the inner surface of the measuring container 20 is washed off, and the solution is put into the clean tank 12.

The water supply path 51 supplies water for diluting the undiluted solution to the cleaning nozzle 53 as a cleaning liquid. Further, the liquid agent passage 55 branched from the liquid agent supply passage 1 joins the water supply passage 51. As a result, the water supply passage 51 can supply the processing liquid (clean liquid) taken out from the clean tank 12 to the cleaning nozzle 53 as a cleaning liquid.

The cleaning nozzle 53 sprays water or a processing liquid toward the inner surface of the measuring container 20 inclined forward.

[Means for determining the amount of water]
The apparatus of this embodiment includes a water amount determining means 80 for determining the amount of water to be introduced for dilution.

The water amount determining means 80 includes the above-mentioned concentration sensor 16C, a flow meter 52, an on-off valve 54, and a control means 81.

The concentration sensor 16C detects the concentration of the processing liquid agent stored in the storage tank 10 before the undiluted solution is charged from the measuring container 20.

The water supply path 51 is provided with the flow meter 52 and the on-off valve 54, and stops the water supply when the amount of water to be charged into the clean tank 12 reaches a predetermined amount.

The control means 81 is for processing that circulates when the addition of a new processing liquid is completed based on the concentration detected by the concentration sensor 16C and the amount of the undiluted solution charged from the measuring container 20. Calculate the amount of diluted water required to optimize the concentration of the solution. Then, when the flow meter 52 counts that the amount of water to be charged into the clean tank 12 has reached a predetermined amount, the control means 81 closes the on-off valve 54 and stops the supply of water. Thereby, the water amount determining means 80 determines the amount of water to be introduced for dilution.

When the amount of water introduced for dilution is less than a predetermined amount, the control means 81 opens the on-off valve 56 to send the clean liquid to the cleaning nozzle 53, and cleans the inner surface of the measuring container 20 with the clean liquid. This prevents the measuring container 20 from being insufficiently washed even when the amount of water introduced for dilution is small.

With such a configuration, in the additional unit 70, the undiluted solution is supplied to the measuring container 20 from the undiluted solution supply path 61, a predetermined amount is weighed, and the undiluted solution is charged from the measuring container 20 into the storage tank 10. The stock solution is added by inclining the measuring container 20. The water to be diluted is supplied by supplying a predetermined amount from the water supply path 51. At this time, by spraying water to be supplied to the inner surface of the inclined measuring container 20, the undiluted solution adhering to the inner surface of the measuring container 20 is washed away and put into the storage tank 10.

[Action effect]
By adopting the above configuration, the present embodiment exerts the following effects.

The present embodiment is a processing liquid diluting device for obtaining a processing liquid by diluting the stock solution with water.
The storage tank 10 stores the processing liquid obtained by diluting the stock solution with water.
The measuring container 20 measures the undiluted solution supplied from the undiluted solution supply path 61.
The liquid amount sensor 30 detects the amount of the undiluted solution supplied into the measuring container 20.
When the liquid amount sensor 30 detects that the undiluted solution in the measuring container 20 has reached a predetermined amount, the charging means 40 charges the undiluted solution in the measuring container 20 into the storage tank 10.

Then, the cleaning means 50 cleans the inner surface of the measuring container 20 by spraying a processing liquid or water during and after charging by the charging means 40.
Even if the stock solution has a high viscosity on the premise of dilution, the stock solution adhering to the inner surface of the measuring container 20 is washed away. The washed-out stock solution can be added to the processing liquid prepared by diluting. This makes it possible to dilute the stock solution at an accurate ratio and appropriately manage the processing liquid.

In this embodiment, as the liquid level sensor 30, a liquid level sensor that detects the liquid level of the undiluted solution supplied into the measuring container 20 is used. This prevents a situation in which the undiluted solution cannot be accurately measured due to the spring not operating normally as in the conventional case. Therefore, it is possible to dilute the stock solution at an accurate ratio over a long period of time and appropriately manage the processing liquid while reducing the maintenance cost.

In this embodiment, the stock solution in the measuring container 20 is charged into the storage tank 10 by tilting the measuring container 20. That is, the undiluted solution is directly charged from the measuring container 20 into the storage tank 10. Structurally, it does not have a flow path or valve through which the undiluted solution to be charged passes. Therefore, it is not necessary to clean the flow path and the valve. Therefore, the cleaning time is not unnecessarily long, and there is no need to maintain the flow path or valve.

This embodiment determines the amount of water introduced for dilution. That is, the concentration sensor 16C detects the concentration of the processing liquid agent stored in the storage tank 10 before the undiluted solution is charged from the measuring container 20. The amount of water introduced by the water amount determining means 80 for dilution is determined based on the concentration detected by the concentration sensor 16C and the amount of the undiluted solution charged from the measuring container 20. By doing so, the stock solution can always be diluted at an accurate ratio, and the processing liquid can be appropriately managed.

[Modification example]
Although the above has described particularly preferable embodiments of the present invention, the present invention is not limited to the embodiments shown, and can be modified into various embodiments, and the present invention includes various modified examples. The purpose is to do.

For example, for charging the stock solution by the charging means 40, a method other than tilting the measuring container 20 can be adopted. For example, the measuring container 20 may be provided with an input path and an on-off valve. As the liquid level sensor 30, a sensor other than the liquid level sensor can also be used. For example, a load sensor can be used if the measuring container 20 is provided with a loading path and an on-off valve.
