These actions of the apparatus are sequentially controlled so that no manual operation is required and the operation becomes highly efficient.

Description

Detailed Description of the Invention The present invention provides a planetary rotating baffle processing machine that performs processing such as polishing, stirring, mixing, or pulverizing the contents by rotating and revolving the processing tanks. It is equipped with a device that automatically opens and closes the top and bottom, and aims to improve work efficiency and save manpower and labor by automating the supply and discharge of contents.

A planetary rotating barrel processing machine has a pair of turrets that allow the bottom processing tank to rotate.The turrets rotate at high speed, and the processing tank also rotates on its own axis, causing the contents in the processing tank to have an acceleration several times that of gravity. It applies a centrifugal force that is several tens of times higher and a high-speed circulation cycle to perform processing such as polishing, stirring, mixing, or pulverizing, and exhibits extremely high processing efficiency. This had the disadvantage that it required a great deal of manpower and time to enter the tank and discharge it out of the tank. Therefore, consideration is being given to automating the supply and discharge of the contents, but the devices currently in use include a method that drains the contents by tilting the tank, and a method that attaches and detaches the lid. The latter requires complicated equipment to remove the lid from the system.

All of them had to be expensive. However, according to this invention, the upper lid of the upright processing tank is opened and closed by pushing down from above, and the lower lid is moved horizontally within the surface of the lid, so the structure is simple and easy to open and close.

An example of a device for stopping the turret S at a fixed position is to install a turret through hole 54'a and a hole S, and determine the stopping position when the floodlight SS, the through hole 54'a or sab, and the phototube 56 are in a straight line. , the turret is stopped at a position where the light emitted from the projector SS is sensitive to the phototube S6. As shown in the figure, when the turret S is not circular, a proximity switch 57 is further provided to stop the turret when the two signals overlap.

The operation of the apparatus of the present invention will be explained based on the mechanism as described above. In principle, all individual operations are automated and unmanned, but some parts may be performed manually. A known sequencer is used for this sequence control, and a sequence is created so that a signal indicating the end of one operation causes five operations to proceed to the next operation. The machining time is regulated by a timer, and after polishing is completed, the main motor
is switched from high-speed rotation to low-speed rotation, and the primary proximity switch s7, floodlight S5, and phototube S6 are turned on. When the signals from both the proximity switch and the floodlight are turned on, the electromagnetic brake 2J is actuated to turn off the power to the main motor J and stop the main motor at the same time. By introducing pressurized fluid into the piston side of the clamp drive cylinder 36 by a signal emitted by the trap that both signals are turned on.

Guide the three Optima clamp drive devices under the processing tank 6a, and pin! I; 2a, 53aft rotor 6a in contact type. This forward movement is sensed, for example, by the contact of the clamp drive device mounting base 3 with the limit switch LS/ (hereinafter LS refers to the limit switch, and description of the limit switch will be omitted) provided on the machine base. . At the same time, pressurized fluid is also introduced into the piston IIK of the cylinder μD, which guides the lid opening/closing fork Sl to below the processing tank lower flange/9a. This advancement is performed when the LSJ provided at the mouth end of the cylinder u9 fits into the recess provided in the piston rod y, and pressurized fluid is introduced into the piston rod of the cylinder for lifting and lowering the lid opening/closing device by the signal issued by the LSJ. Therefore, the fork 51 is pulled up, and the notch part of the fork is aligned with the pins a and 53a.
mated with. This fitting is sensed by a portion of the slide device 31 coming into contact with the LSJ provided at the end of the cylinder 300.

When pressurized fluid is introduced to the piston side of the cylinder 39 by the signals LSt, LSJ, and LS3, the rack moves, and the clamp drive wheel rotates, thereby causing the clamp to move. The drive pin ψ3a and the rotor 116afi (rotate) release the Optima clamp 23a and release the lid 2/a. It is detected by the contact of LS4t fitting into the recess provided in rack IAolC, and after the clamp drive device mounting base 3g is retracted by the signal issued by LS4t, pressurized fluid is introduced to the piston rod side of cylinder ψde. , the piston rod y moves to the right and the lid tia
is open.

The contents are discharged and fall onto the sorting device. This lid 2/a
The opening of the machine is detected by the LS- and starts the vibration motor 4♂ of the sorting device 33, so that the contents are sorted and the processed workpiece is sent to the next process.

The media is sent to the media storage tank (not shown) by a separate media transport device (not shown). Pressurized fluid is supplied to the piston side of the fluid pressure cylinder X at the start of the vibration motor 5g. As it is introduced, its piston rod lowers and pushes down the valve pusher seat/73. Valve /Aa is therefore released. This depression is detected by the LSsK installed at the mouth end of the cylinder 300,
A separate water washing device is used to wash the inside of the processing tank 4a, the opening, and the top surface of the lid νa.The washing time is regulated by a timer, and the signal emitted by the timer applies pressure to the piston side of the cylinder ψ9. To introduce fluid, the lid 2/a is introduced between the machining tank 6a and the Optima clamp, ZJa.This introduction is detected by the LSJ, and the signal issued by the LSJ causes the clamp drive device mounting base 3♂ to move into the machining tank. Guide it under 4a, bin 32m, 3
3m to the rotor Na.Next, pressurized fluid is introduced into the piston rod side of the cylinder 39, so the rack slides and the optional part is turned on.
nM copper is detected by the IL8 da, and the processing tank lower lid sliding device 31 and the three Optima clamp drive devices are evacuated based on the signal generated by the IL8 da. At the same time, a separately manufactured content charging device 6Q is driven to charge a predetermined amount of unprocessed workpieces, media binding, compound solution, etc. into the processing tank 4a from the content charging chute 9. At this time, it is convenient to add the compound solution last and also to wash the valve seat of the valve/Aa. The input time is regulated by a timer, and when the input is completed, pressurized fluid is introduced into the piston rod side of the cylinder 30, so the valve push seat /7a is raised by the action of the spring /lla, and the square /Aa is closed. The rise in valve/Aa is detected by LSS.

As some of the contents have been exchanged through the above operations, L
The main motor j is rotated at low speed by the SS signal, and the contents of the pond tank are replaced by the same operation.

When the contents have been replaced in this way, the main motor j is switched to high speed rotation, and the processing tank 4B is rotated by 50 rotations of the turret.
With the revolution of tb, the chain wheel 7a, the chain wheel b and the fixed chain wheel q2
, 9bK causes the contents to flow under a strong centrifugal force, thereby machining the workpiece. At this time, when polishing, the processing tank is made into a 5- or t-gonal shape, and the diameters of the fixed chain wheels 5J and Wb are made equal to each other on the chain wheels 7a and 7b, and the revolution speed N and the rotation speed n are set in opposite directions. and be equal;
It has been confirmed that when the condition n/N=-t is satisfied, a fluidized layer is formed in the upper layer of the mass, and good polishing can be achieved.

As described above, according to the present invention, the planetary rotating barrel processing machine rotates the turret on which the processing tank is mounted at high speed, rotates the processing tank, and performs processing such as polishing, stirring, mixing, or pulverizing the contents. In this method, a processing tank with multiple cylinders is arranged vertically, the valve at one end is pushed down from above, and the lower valve is made to be able to slide in the same plane as the lid, so the lid can be attached and removed reliably and the processing Since no obstructions are left inside the tank, it has a good volumetric effect, is easy to automate, and has a simple configuration, making it possible to obtain an ideal planetary rotating barrel processing machine. effective.
