Description

[Detailed description of the invention] (Industrial application field) This invention is a fully automatic barrel processing machine that uses dry media, by supplying a fixed amount of abrasive and oil to the media whose performance has deteriorated after use. This invention relates to a fully automatic dry media readjustment device for barrel processing machines, which aims to improve the performance of barrel processing machines.

(Prior Art) Conventionally, it has been customary for dry media to be discarded when they deteriorate due to use.

(Problem to be solved by the invention) The dry media in this invention is the media used for dry barrel processing, and is usually made from crushed organic materials such as walnuts, corn cobs, etc. Refers to media with abrasives and oil attached. These media are used for rotary barrel processing, spin processing, centrifugal barrel processing, etc. When processed, the abrasive becomes pulverized, the oil and fat change, and the workpiece becomes pulverized. Processing ability deteriorates due to contamination with chips. This idea attempts to restore the performance of the media by mixing a certain amount of abrasive material and oil and stirring it into the media whose performance has deteriorated in this way.Furthermore, the device of this idea is installed as part of fully automatic barrel machining. The aim is to allow dry media to be used for long periods of time without having to be replaced, and to achieve complete automation.

(Means for solving the problem) This invention provides three stations in the middle of the conveyance path for a certain amount of dry media that has been used for a certain period of time and is transported by a conveyor, and the first station polishes a certain amount of dry media. The material is supplied, stirred at the second station, and a certain amount of oil is added at the third station to be used for the next dry barrel processing.

That is, this invention provides an apparatus for reconditioning dry media in which an abrasive and oil are attached to organic media, and includes a device for transporting a container loaded with dry media after use, and a device for feeding the abrasive into the container. A fully automatic dry media for a barrel processing machine, comprising an abrasive material supply device, an oil quantitative supply device that supplies a fixed amount of oil into the container, and a stirring device that stirs the used dry media and the abrasive and/or oil. It is a readjustment device. The abrasive supply device uses, for example, a parts feeder to supply the abrasive material in a fixed quantity. Further, the oil constant supply device uses a combination of a cylinder and a piston, and uses a fluid pressure cylinder as its driving source.
The stirring device is installed after the abrasive material supply device, after the oil constant supply device, or after each of the above-mentioned devices.

(Function) According to this invention, the dry media can be used for a long time and over a long cycle, and the media can be readjusted unattended.

(Example) Fig. 1 shows an example of the device of this invention, and even if the transport container for transporting the dry media used on the transport conveyor 1 is a barrel tank, the dry media is transferred from the barrel tank to another container. There is no problem even if you have done so. This conveyance container is sequentially stopped at three stations, ie, the abrasive quantitative supply device 2, the stirring device 3, and the oil quantitative supply device 4, by a known fixed position stopping device. The structure of the abrasive quantitative supply device 2 is as follows.
As shown in Fig. 3. In FIG. 2, a bridge groove 5 is provided above the conveyor 1, and a known vibrating parts feeder 6 is installed above it. The parts feeder 6 is equipped with a vibration motor inside, and by rotating and oscillating the motor, the abrasive material charged in the bottom part 7 is raised along a spiral path 8 and sent to an outlet 9.
Then, the abrasive material is charged into the transport container 11a on the transport conveyor 1 via the conduit 10. The additives in this abrasive material are regulated by the operating time of the parts feeder. 31 is a hopper.

The structure of the stirring device is shown in FIGS. 4 and 5. Fourth
In the figure, the transport container 11b has gripping arms 12a, 12
It shows a state where it is gripped and stopped at a fixed position by .b. A support stand 13 is fixed on the floor outside the conveyance device, and two guides 14a, 14 are attached to the support stand 13.
b stand upright at predetermined intervals. Sliders 15a and 15b are attached to the guides 14a and 14b so as to be able to slide up and down, and the slider 15
The lower part of the piston rod 18 of the lifting hydraulic cylinder 17 is fixed upward to the center plate 16 fixed between a and 15b, and a stirring rod 20 with a motor 19 is attached to the front via a connector 32. ing. That is, the transport container 11b is
When the stirring rod 20 is gripped and stopped at a fixed position by the handles 12b and 12b, the stirring rod 20, which had been retracted upward, is lowered by the action of the fluid pressure cylinder 17, and its tip is placed inside the media in the transport container 11b. inserted. Then, when the motor 19 is started and the stirring rod 20 is rotated, the media is stirred. After a predetermined period of time has elapsed, the motor 19 is stopped and the stirring rod 20 is raised by the hydraulic cylinder 17. Then, the gripping arms 12a and 12b release their grip and release the transport container 11.
b is sent to the third station. The external appearance of the oil constant supply device 4 of the third station is shown in FIG.
In FIG. 6, the oil stored in the oil tank 21 is led to the constant supply cylinder 24 through the pipe 22 and is discharged from the pipe 23 as shown by the arrow 33. The structure of the metering cylinder is as shown in FIG. That is, a piston 25 is slidably assembled inside the dispensing cylinder 24, and one end of the piston 25 is fixed to one end of a piston rod 27 of a hydraulic cylinder 26. pipes 22, 23
are each opened at the tip of the center hole of the cylinder 24, and are each provided with a check valve 28, 29 to prevent oil from flowing backward. That is, when the piston rod 27 moves to the right as shown by the arrow 34 in FIG. If it moves, cylinder 24
The oil inside flows in the direction of arrow 36 through pipe 23 and is introduced into the conveying container. Since a fixed amount of oil is introduced into the cylinder 24 at this time, a fixed amount of oil is also discharged. In order to adjust this amount, a stopper 30 is provided, and by moving it in and out, the piston stroke of the piston 25 is adjusted, and the amount of discharged oil is adjusted. The transport container that has been mixed with oil is sent to the next process.

In the above embodiment, the abrasive material supply device was placed first and the oil quantitative supply device was used after, but the reverse may also be used, and one stirring device was used after the abrasive material supply device. One unit may be used later, or two units may be provided, one unit after each, and both fall within the technical scope of this invention.

(Effects of the invention) As described above, according to this invention, a specified amount of abrasive material is supplied and stirred into the transport container loaded with dry media, and a certain amount of oil is added. Since the dry media can be used for long periods of time and in long cycles, and readjustment can be fully automated, it is highly effective in saving resources, manpower, and labor.
