[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fully automatic centrifugal flow barrel processing apparatus.

[0002]

2. Description of the Related Art A conventional centrifugal flow barrel polishing apparatus has a disadvantage that the actual polishing step is simple and can be completed in a short time, but various operations involved in replacing the contents are complicated and require a long time. It was difficult to clean around the device.
In order to solve this problem, various proposals have conventionally been made as described below.

Japanese Patent Application Laid-Open No. 48-16295 discloses that one end of a plurality of processing cylinders that rotate around a revolving shaft arranged in a horizontal direction is rotatable relative to the tip of a feeder cylinder that rotates integrally with the revolving shaft. It discloses that the feeder cylinder is connected to the other end of the feeder cylinder through a hollow portion in the orbital shaft to one end opening of the orbital shaft, and the work and the abrasive are continuously supplied from the one end opening of the orbital shaft. The polished contents are discharged to the outside from the other end opening of each processing cylinder.

Further, it mounted for rotation processing tube to the turret revolves, also possible to discharge the polished contents of processing cylinder the turret is tilted about a horizontal axis to the outside
Is known . Furthermore, <br/> in JP 55-46822 Patent Gazette is fixed to the revolving shaft that extends vertically turret to rotate freely holding a plurality of rotation axes around the revolution axis,
A pedestal and a lid are provided on each rotation shaft. Then, the processing tank having the upper end opening filled with the unpolished contents is placed on each receiving table, and the rotating shaft and the revolvable clamp device are driven together with the rotation axis to move one of the receiving table and the lid in the axial direction. Slide and close the upper end opening of each processing tank by the lid, and in this state, rotate the revolving shaft and each rotation axis synchronously to rotate and revolve the processing tank, and after completion of centrifugal flow barrel polishing performed by it, Slide one of the cradle and the lid in the opposite direction to the above to remove the lid from the processing tank, remove the polished processing tank from the cradle by the handling device, and place a new processing tank on the empty cradle, The lid is slid in the axial direction again to seal the upper end opening of each processing tank and press the processing tank in the axial direction, and then the next polishing cycle is performed.

[0005]

THE INVENTION Problems to be Solved However, the above-mentioned
According to one of the prior arts described above , it is not easy to completely remove the polished contents adhering to the inside of the processing cylinder, and the above-described prior art is
According to another one of the techniques, the processing tank removed from the apparatus can be washed in another department, so that there is an advantage that removal of polished contents and easy introduction of unpolished contents are easy, but still below. There were the drawbacks mentioned.

That is, when the processing tank at the upper end opening is removed, the polishing liquid or polishing powder attached to the lower surface of the lid portion drips or scatters, so that the device surface or floor surface below the lid portion gets wet or contaminated. In some cases, the working environment is deteriorated, and in some cases, it adheres to the rotating parts of the apparatus and reduces its durability. In addition, while removing the processing tank filled with the polished contents from the apparatus, or loading the processing tank filled with the unpolished contents into the apparatus, the polishing liquid or the abrasive powder jumps out of the processing tank. In some cases, similar problems may occur. Of course, this problem can be alleviated by making the processing tank deeper, reducing the content filling amount, or reducing the processing tank transfer speed, but as a result, the productivity decreases and the rotating mass increases. This leads to an increase in the size of the device.

In addition, since the rotation and revolution of the processing tank are at a high speed, the processing tank and the lid are prevented from being displaced in the radial direction due to the torque or centrifugal force, and the contents are prevented from leaking to the outside.
The clamp mechanism that rotates and revolves together with the rotation shaft needs to strongly press the lid against the processing tank, which requires a large-sized apparatus for clamping, and has a disadvantage that the rotation and the revolving mass increase.

Further, the above-mentioned apparatus is a vertical centrifugal flow barrel polishing apparatus in which a revolution axis and a rotation axis are vertically arranged. In such a vertical apparatus, the depth of a processing tank is reduced by the influence of gravity during rotation. It is difficult to increase the content filling amount by increasing the depth. Such a problem does not occur in the horizontal centrifugal flow barrel polishing device in which the revolving shaft and the rotation shaft are horizontally arranged. It was difficult to adopt.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a fully automatic centrifugal flow barrel processing apparatus capable of improving the working environment while avoiding an increase in the size of the apparatus and a decrease in productivity. It is a problem to be solved.

As described above, the fully automatic centrifugal flow barrel processing apparatus of the present invention has an excellent effect that the unprocessed barrel is sealed in advance, so that it is easy to handle and can be clamped by the clamping shaft pair. Play. Hereinafter, this will be described in more detail. (A) Since the barrel can be attached and detached, filling the barrel with contents and taking out the contents from the barrel outside the device,
The cleaning of the barrel can be carried out, the working efficiency can be greatly improved, and the environment around the apparatus and its surroundings does not deteriorate.

That is, when the barrel is fixed to the device, the barrel is opened, the contents are taken out, and
Cleaning, filling of contents, and sealing of the barrel must be performed in order, which requires a long time and makes automation difficult in terms of space. Due to the barrel attachment / detachment, only the barrel attachment / detachment time can be expected for the device, and the working efficiency of the device is greatly improved.
In addition, the above operations are performed in separate work spaces,
Since the barrel only needs to be transported, automation is easy.

(B) Since the barrel is always attached to and detached from the apparatus in a sealed state, it is possible to completely prevent the polishing liquid or abrasive powder from dripping or scattering on the apparatus surface or floor surface when the barrel is attached or detached as in the conventional case. And an extremely favorable working environment can be realized. In addition, it is possible to prevent the polishing liquid, the polishing powder, and the like from adhering to a rotating portion of the apparatus and reducing the durability.

(C) Since the barrel is always attached to and detached from the apparatus in a sealed state, the barrel can be quickly attached and detached, and the working efficiency of the apparatus is further improved. (D) Since the barrel is always attached to and detached from the device in a sealed state,
The present invention can be applied to a horizontal centrifugal flow barrel processing device in which the revolution axis and the holding axis are horizontal. (E) The holding shaft pair only needs to prevent the barrel from coming off due to centrifugal force, and it is not necessary to strongly press the lid on the processing tank having the upper end opening unlike the above-mentioned prior art, and therefore, the barrel holding mechanism that rotates and revolves. Can be reduced in size and weight, the configuration can be simplified, the rotating mass can be reduced, and the size of the device can be reduced.

In particular, in the barrel according to the present invention, the main cylinder having an opening parallel to the axis of the cylinder is shielded by the cover, and a pair of dovetailed flanges respectively extended from the main cylinder and the cover are provided. Since the elastic sealing layer is disposed on at least one of the close surfaces and the two dovetail-shaped flanges are sandwiched by the grooved clamp members, the sealing of the opening and the opening operation are easy, and a good seal is provided. Can be realized.

Further, when the centrifugal force due to the rotation of the barrel acts on the clamp member, there is a groove in the clamp member, which urges the shaped flange in the direction of clamping, and as a result, the clamping force of the elastic sealing layer increases. This provides an excellent effect that the sealing is further improved. In addition, the barrel handling mechanism extends the barrel

It is important to note that the holding plate 8
The locking rods 57 and 67 can freely enter and exit in the circumferential direction of the revolving shaft 2 between the pair of holding plates 85 in a state where the locking rods 5 are not displaced in the barrel non-holding direction. Thus, the holding plate 85 does not hinder the revolving motion of the locking rods 57, 67. In order to release the barrel 7 scheduled to be released from the rotation holding mechanisms 5 and 6, the revolving shaft 2 is stopped at a predetermined stop phase, and the locking rods 57 and 67 fastened to the predetermined holding shafts 52 and 62 are released.

First, the clamp member 75 is connected to the flanges 71a, 71a.
Since the flanges 71a and 72a and the rubber lining layers 77 and 78 are fitted into the groove 75a of the clamp member 75 by sliding in the longitudinal direction from one end of 2a, it is easy to press the cover 72 slightly against the main cylinder 71. To complete the clamp. Further, a rubber lining layer 7 for protecting the inner surfaces of the main cylinder 71 and the lid 72 during polishing.
7, 78 are extended on the flange portions 71a, 72a to provide an elastic reaction force at the time of clamping, so that a special elastic member for applying the elastic reaction force at the time of clamping is not required. Can be.

Further, the both flange portions 71a, 72a are
Is formed thicker as the distance from the opening increases, it becomes impossible for the clamp member 75 to come off in the direction away from the opening. In particular, the clamp member 75 is urged in a direction away from the opening by the centrifugal force during the rotation of the barrel 7, and when the clamp member 75 is displaced by this urging, as can be seen from the sectional shape of FIG. Urges the flanges 71a, 72a in the close direction, so that there is an advantage that the seal is improved on the contrary.

Next, the barrel handling device 10 will be described with reference to FIG. 3, FIG. 12, and FIG. The barrel handling device 10 is capable of self-propelled suspension along a rail 101 extending in a horizontal direction perpendicular to the axial direction of the revolving shaft 2, and is suspended from the self-propelled suspension 102 so as to be able to move up and down. The self-propelled suspension unit 102 and the barrel holding unit 103 are operated by electric power supplied through a power supply mechanism (not shown).

The barrel grip 103 is a pair of arms 103
a, and the distal end portion of the arm 103a can grip the clamp member 75 of the barrel 7. FIG. 12 shows arm 1
03a shows a state where the barrel 7 is gripped, and FIG. 12 shows a state where the grip of the barrel 7 by the arm 103a is released. The conveyor 104 intermittently operated extends in the horizontal direction perpendicular to the paper surface in FIG. 3, carries in the unprocessed barrel 7 from the upstream side, and unloads the processed barrel 7 received from the barrel holding unit 103 to the downstream side. I do.

Hereinafter, the operation of the fully automatic centrifugal flow barrel polishing machine will be described. Now, it is assumed that the polishing process has been completed. First, the motor 30 is stopped to stop the barrel 7 from rotating and revolving. When the motor 30 stops, the motor 30 is switched to low-speed rotation, and a position detection sensor (not shown) disposed on the column 11 or the column 14 determines whether the rotation angle of the disk portion 3 reaches a predetermined stop angle. Is detected, and the disk portion is always stopped at a predetermined stop angle. In this stopped state, the barrel 7 to be released from the rotation holding mechanism 5, 6
(Hereinafter, referred to as target barrel 7) is stopped at the upper right position y in FIG.

Next, the barrel handling device 10 travels just above the target barrel 7. Next, the barrel holding unit 103 of the barrel handling device 10 holds the target barrel 7. Next, the rotation holding mechanism 5 for holding the target barrel 7,
Hydraulic cylinders 8 adjacent to the outside of each of the cylinders 6 operate,
The holding of the target barrel 7 by the rotation holding mechanisms 5 and 6 is released. Next, the barrel handling device 10
4, and then the barrel gripper 103 descends and places the target barrel 7 on the conveyor 104. Next, the conveyor 104 moves by a predetermined transport distance, and the unprocessed barrel 7 stops immediately below the barrel holding unit 103. Next, after the barrel gripper 103 grips the unprocessed barrel 7,
Ascends, then the barrel handling device 10 moves the raw barrel 7 to the upper right position y, then the hydraulic cylinder 8
, The urging of the rotation holding mechanisms 5 and 6 in the barrel non-clamping direction is released, the raw barrel 7 is held by the barrel support plates 64 and 54, and then the raw barrel 7 is gripped by the barrel holding unit 103. Release, raise barrel grip 93 and retract it onto conveyor 104, after which motor 30
To rotate the revolving shaft 2 by a predetermined angle, and thereafter, the respective barrels 7 are sequentially replaced.
