Description

DETAILED DESCRIPTION OF THE INVENTION The present invention involves controlling the vibration of the barrel tank in order to control the amount of mass introduced onto the sorting net to a set mass amount when sorting the mass of a vibrating barrel processing machine. The present invention relates to a method and apparatus for selecting a vibrating barrel processing machine, which uses the output of a mass detection sensor to control vibration.

Conventionally, during sorting in vibrating barrel machining, the amount of mass (referring to the mixture of workpiece and media, hereinafter the same) introduced into the sorting net is large at first, but decreases as the workpiece is sorted. There were times when it was difficult to sort. Furthermore, if too much mass is initially introduced, there is a risk that media that cannot be sorted will be ejected together with the workpiece, making complete sorting impossible. However, according to this invention, the amount of mass on the sorting net is detected by a sensor such as a limit switch or a photoelectric switch, and an unbalance is installed on the rotating shaft of the motor in order to make the detected mass amount equal to a predetermined mass amount value. Since the rotation speed, lead angle, or weight of the weights are controlled by a processor, it is possible to always sort under optimal conditions, and the sorting time can be shortened and complete sorting can be achieved. The control of the rotational speed of the unbalanced weight of the vibration electric motor in order to control the vibration of the barrel tank will be described in detail below along with embodiments. Further, regarding the control of the advance angle of the unbalanced weight, a patent application filed by the applicant of the present application filed on 3A/9/1989.
The apparatuses disclosed in No. 90J'7 and Japanese Patent Application No. 57-37g7g can be used. Furthermore, regarding the control of the weight of the unbalanced weight, there is a patent application filed by the applicant of the present application. ;A-/! It is possible to utilize the device of the invention of iA'lO1.

That is, the details of this invention will be explained below with reference to accompanying figures. Figures 1 and 2 show an annular vibrating barrel processing machine equipped with a sorting device, and the inner surface of the barrel tank is lined with natural rubber or synthetic resin.
The inner cylinder is covered with a lid/b. The example shown in Fig. 1 is equipped with a vibration motor //, with unbalance weights /2, /2a fixed to both ends of its rotating shaft, and this vibration motor // is mounted on the tank 7 lange /3. Tighten the bolts and write a few poems. Such a barrel tank and a vibration motor are integrated, and the tank flange is suspended and fixed on a base/6" spring/rest, and as the motor rotates, vibration is given to the barrel tank and the mass, so that the workpiece is be processed by the media. In the figure, 77 is a cover.

The types of processing performed by this processing machine include various processing such as polishing, crushing, mixing, diffusion, stirring, drying, and chemical processing.1. ,
Any media may be used depending on the purpose of processing.

In addition, this processing machine is equipped with a rotating weir and a sorting net 7 for sorting on three sides of the barrel tank. As shown by a chain line in FIG. 1, at the end of machining, the rotary weir 1 is rotated and its tip is brought into contact with the top ridge 3a of the chevron-shaped fixed weir, so the gap is closed and the mass of the rotary weir is The media rises on two sides and onto the sorting net 7, and the media falls downward and is processed again, and the workpiece is taken out from the tip of the sieve and out of the twine.

Furthermore, in order to increase processing efficiency, a mass flow adjustment lid O, guide grates G, GA, etc. are attached, but these are not necessarily necessary for carrying out the present invention.

As a sensor for detecting the mass amount on the sorting net 7, for example, as shown in FIG. 3, a limit switch 2! is installed on one side of the sorting net 7. i, 23 a, λ, qb and touch the limit switch 2, 2Sa, 1 that contacts 23b.
Needle λotsu, 21. a. Drop the 2 Osu. The tip of the needle is placed at a position where it contacts the mass introduced onto the sorting net. When the position of the top surface of the mass introduced onto the sorting net 7 is 2g (as shown by the chain line in the figure), the tip of the hook 2 contacts, and when the position of the top surface of the mass is 2ga, as shown by the chain line in the figure, the needle 2/ , a are in contact with each other, and when the two sides of the square are at the dotted line xgb in the figure, the tips of the needles λ4c are in contact with each other. That is, needle ease, 26; 1 is the limit switch, 2
If both 2 and 2 a are turned on, the rotational speed will be constant and the optimum sorting state will be achieved. Also, needleyoshi, 21. a, this is the limit switch 2! , 23a and 23b are all turned on, the rotational speed of the vibration motor is reduced by the frequency converter, and the amount of mass on the sorting network is reduced. Also needle 24
When only the limit switch Δ is turned on, the rotation speed of the vibration motor increases by the frequency converter,
The amount of mass on the sorting net increases. Next, another example of the sensor is shown in FIG. 9, in which a photoelectric switch 27 is placed below the sorting screen.
1.27a, 2'71) are provided, and a light projector (not shown) is provided at a position offset from the photoelectric switch. This photoelectric switch detects the falling position of the media sorted on the sorting net 7, and the optimal sorting state is when the photoelectric switches 27 and 27a are operating. Therefore, the same operation as the embodiment shown in FIG. 3 is performed. In the embodiment shown in Fig. 3, there is a risk of malfunction when sorting a relatively large workpiece, but in the embodiment shown in Fig. 4, the media is measured, so the measurement accuracy depends on the size of the workpiece. There is no fear that it will happen.

FIG. S is a block diagram when controlling the motor rotation speed. As shown in the figure, the signal from the sensor is amplified and inputted to the control device (part of the grosser). If the sorting power is insufficient, the motor rotation speed is increased, and if the sorting power is excessive, the motor rotation speed is decreased. to control.

Next, in this invention, to control the advance angle of the balance weight, for example, the device shown in FIG. 6 is used. That is, the main motor 30, which rotates in free run, and the slave motor 3/ are fixed vertically, with the rotation shaft vertically, on the inside of the cylinder at the end of the vibration bar, and the rotation of each motor 30. The base ends of unbalanced weights 3, 2, and 330 are fixed to the shafts, and pulse generators 3, 35 are installed around the outside of the unbalanced weights σp, and the tips of the unbalanced weights 3, 33 are fixed to the shafts. Dog 36.37 on the side
is installed. In the above example, dog 3 Otsu, 37
When the pulses generated in response to the pulse generators 3q and 35 are input to the microphone μm computer (CPU) 3g, the unbalanced weight of each motor 30.3/
Positions 7 and 33 can be detected. Since the output of the microcomputer is connected to the input of the frequency converter 3, the advance angle of the rotation angle of the unbalanced weight 330 is detected based on the rotational angle position of the unbalanced weight 3.2, and this angle is If the angle deviates from the pre-commanded angle, the frequency converter Kf, 3q controls the rotational speed of the slave motor 3/ so that the rotation speed matches the set value.
Directions to. The frequency converter 3q is a slave motor J3.
The number of rotations of the two motors 30.3/ is changed according to instructions given by the microcomputer 3g, and once the lead angle is obtained, the power frequency is changed so that the number of rotations of both the motors 30.3/ is the same, and this is always maintained. Provides feedback to keep the advance angle constant. The vibration is controlled to a desired value by feeding the above information to a microcomputer and setting the unbalance weight to a predetermined advance angle. In the figure, θ is a synchroscope,
ri/ is the power supply. The embodiment shown in FIG. 7 attempts to control vibration by changing the centrifugal force of the unbalanced weight.

That is, a fixed weight ``Gugu'' and an adjustment weight tis are placed opposite to each other on the rotating shaft 11.3 of the vibration motor II2. The adjusting weight 5 fixes the base end of the housing case horizontally to the rotating shaft/I3, and has a cylindrical lid lI7 screwed onto the tip.
- An adjustment weight and a spring qq are sequentially installed between the inner side of the base end of the ringing width and the cylindrical lid lI7.

In the above, when the rotation of the rotating shaft is controlled, the weight moves inward or outward as indicated by the arrow SO due to the balance between the centrifugal force applied to the weight and the elasticity of the spring q9. The lance value between the weight and the weight changes, and the amount of mass introduced into the sorting net can be adjusted by changing the excitation force.

As mentioned above, according to the present invention, during the sorting process in vibrating barrel machining, the amount of mass rising on the sorting net is detected and controlled by the processor so as to maintain it at the set value.
Therefore, there is a starting point that allows efficient sorting by always introducing and automatically setting the optimal mass amount.
