Description

Detailed Description of the Invention (Field of Industrial Application) This invention relates to a mass (referring to the charge charged into a barrel tank, generally known as (refers to a mixture of workpieces, abrasive materials, and compound solutions, etc.) used in the industrial field of barrel processing, such as the manufacture, sale, or use of mass maintenance devices for automatic barrel processing machines for thin workpieces. It is.

(Prior Art) Conventionally, a mass maintenance device for an automatic barrel processing machine for thin workpieces has been the same as a general-purpose device not for thin workpieces.

(Problems to be Solved by the Invention) However, when a general-purpose mass maintenance device is used for thin workpieces, the workpieces stick together during maintenance and polishing, which not only prevents effective polishing but also prevents polishing from being completed. It took a lot of effort and time to peel them off one by one afterwards. Also, when charging mass into the barrel tank, workpieces stuck to the charging chute and had to be removed manually after maintenance.

As mentioned above, there is a problem in thin workpieces such as thin plates or flakes that it is necessary to prevent the workpieces from sticking during maintenance or polishing.

(Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention provides a mass maintenance device in which synthetic resin particles, i.e., small balls, are A chute is equipped with a device for charging small pieces or powder, and synthetic resin round rods are laid and glued on the underside of the chute for charging mass into the barrel tank.
This prevents workpieces from sticking to the chute and solves the above-mentioned conventional problems.

(Action of the invention) According to this invention, thin workpieces such as thin plates or flakes to be barrel-processed no longer stick to each other during processing, nor to the charging chute, etc. when charging into a barrel tank. .

(Embodiment) FIG. 1 is a front view of an embodiment of the present invention, and FIG. 2 is a side view thereof. In the figure, reference numeral 1 denotes a frame for supporting the entire apparatus, and a hopper stay 2 is fixedly protruded from the side of the frame in the lateral direction, and a hopper 3 is supported by this hopper stay 2. Details of the hopper are shown in FIG. The outlet 3a of the hopper 3 is provided with an outer cylinder 4 on the lower side, and a connector 7 is provided on the lower surface of the outer cylinder 4. It is connected at 6a. On the inner surface of the hopper 3 and the lower surface of the outer cylinder 4, round rods 8 made of synthetic resin (for example, made of vinyl chloride) are closely fixed in parallel as shown in FIG. This round bar 8 is one of the main features of this invention, and prevents thin workpieces such as thin plates or flakes from sticking to the chute. Further, when loading a workpiece, the outer cylinder 4 moves forward and protrudes above the bucket 9 to be in a position where the workpiece can be loaded into the bucket 9, and when it retreats, it no longer interferes with the lifting of the bucket 9. There is. Reference numeral 10 designates a separate workpiece housing, which is shown in a position where the workpiece is accommodated and tipped over to load the workpiece into the chute, and an arm 11 supports the workpiece housing in the tipped-over position.

A synthetic resin particle quantitative supply device 12 is installed above the hopper 3. When synthetic resin grains, spheres, chips, or coarse powder (hereinafter referred to as grains) are fed from the synthetic resin grain quantitative supply device 12 into the hopper together with the workpiece, the synthetic resin grains are fed into the hopper together with the workpiece. The resin particles adhere to the workpiece surface and prevent the workpieces from sticking together. The particle size of the synthetic resin particles is suitably 0.5 mφ or less. For example 0.5#l
If #+φ or more, the adhesion of the synthetic resin particles to the workpiece surface is poor and good effects cannot be obtained. An example of the structure and operation of the synthetic resin particle quantitative supply device 12 will be explained with reference to FIGS. 5 to 7. In this embodiment, synthetic resin particles are charged inside the rotating cylinder 13, and a slit 15 is left between the rotary cylinder 13 and the lid 14, and while the slit 15 faces downward, the synthetic resin particles are inserted into the rotating cylinder 13. It has a falling structure. Further, the width of this slit 15 can be changed by sliding the lid 14 open. That is, by changing the rotational speed of the rotating cylinder 13, the width of the slit 15, the physical properties of the synthetic resin particles, etc., the amount of synthetic resin particles that can be supplied at one time can be changed (FIG. 7).

Furthermore, a metering plate 30 is installed inside the rotating cylinder 13 to separate the internal space into two parts A and B, and a slit 31 is provided between the tip of the determining plate 30 and the inner peripheral surface of the rotating circle 813. The amount of synthetic resin particles 32 falling into the bucket 9 is regulated by the slits 31 and 15. Quantitative separation will be explained below with reference to figures a to d of FIG. 7. The rotating cylinder 13, as shown in FIG. 7a,
It is stopped in such a state that the synthetic resin particles are accommodated in part A. Next, when rotating the rotating cylinder 13 in the direction of the arrow 33,
As shown in Figures b and 0, some of the synthetic resin particles flow out to part B. This flow rate can be adjusted as appropriate depending on the rotation speed, the width of the slit 31, etc. Next, when the state shown in figure d is reached, B
The synthetic resin particles 32 that have moved to the lower part fall from the slit 15. This fall amount can be adjusted as described above. Then, when the state returns to the state shown in Figure a, the rotation of the rotating cylinder 13 stops. This stop position is detected by the proximity switch 16. Also, due to some trouble,
Even if the rotating cylinder 13 stops at the position shown in figure d, only the part of the synthetic resin particles 32 that has moved to the B section will fall, and most of the synthetic resin particles 32 inside the rotating cylinder 13 are stored in the bottom section. There is. Therefore, even if an unexpected trouble occurs, it can be dealt with.

In addition, inside the bucket 9, there is a chute 17 for supplying polishing stones for resupplying selected polishing stones after polishing is completed, a fluid pressure cylinder 18 for retracting the chute, and replenishment of worn polishing stones if necessary. Abrasive stone quantitative supply device 19,
A compound solution quantitative supply device (manufactured separately, not shown in the figure) is included.

In this way, the bucket 9 containing -charges of squares is connected to a pair of chains 21, 21 fixed to its sides.
When the bucket 9 is moved upward by the drive motor 20, the bucket 9 is overturned by the guide above. There, the mass is charged into the barrel 124 via the upper hopper 22 and the upper barrel 23. The mass charging position (Fig. 2) is located above the barrel tank 24 from which the lid 25 has been removed by a separate lid removal device 26, and when the lid is closed and the barrel processing device is in operation, the upper hopper moving cylinder 27
Take shelter at position 8. Although the barrel tank 24 is that of a centrifugal flow barrel polishing machine in FIG. 2, it may be a barrel tank of a rotary barrel polishing machine, a vibratory barrel polishing machine, or any other type of barrel polishing machine. do not have. Moreover, on the inner surface of the upper hopper 22 and the inner surface of the upper outer cylinder 23,
As shown at 28 in FIG. 1, synthetic resin round rods are bonded to the inner surfaces of the hopper 3 and outer cylinder 4 to prevent workpieces from sticking.

(Effects of the Invention) According to the maintenance device of the present invention, when barrel processing a thin workpiece such as a thin plate or flake, the thin workpiece does not stick to the hopper or chute before charging into the barrel tank. , or if the workpiece sticks inside the barrel tank during polishing,
Alternatively, it can prevent sticking to the barrel tank wall, so it has a medium movement that enables uniform polishing.
