Description

[Detailed description of the invention] Industrial application field: This invention feeds and applies the supplied disk material to the processing location according to each processing stage using a plurality of hanging hooks, and achieves the desired finish. This relates to a polishing device that can be sent to the next stage of the process.

Background of the invention: A disk with a smooth surface, such as a disk used to record related elements of electronic equipment, is made of, for example, a disc-shaped aluminum material that has been polished to a smooth surface through the required stages. In the polishing process, a disc, which is a workpiece to be polished, is sandwiched between opposing rotating grindstones, and both grindstones are rotated while applying a pressing force. At the same time, the disk rotates in the same direction as the rotating grindstone due to the frictional force between the two rotating grindstones, and polishing is performed smoothly over the entire surface area of the front and back of the disk. Therefore, it goes without saying that it is preferable for the disk to always rotate within the same plane, and a double-sided polishing device that polishes such a disk to a smoother finished surface than the unpolished state requires The disk holding mechanism can reliably receive the disk sent into the part and rotatably hold the disk in close contact with the polishing surface of the rotary grindstone, and only uses an additional force that is appropriate to the material and shape of the disk. A conveying means must be provided that can feed the workpiece to the rotary grindstone so that the above-mentioned conditions can be obtained, the workpiece can be polished smoothly, and the workpiece can be sent out without damaging the finished surface.

Purpose of the invention: In view of the current situation, the present invention has multiple polishing stages in which a disc made of a disc-shaped aluminum material is polished according to its condition. This was developed with the aim of proposing a polishing device with a conveyance means that would allow disks to be fed and removed without damaging the shape of the disk, from pressure polishing to smooth surface finishing. The double-sided polishing mechanism parts are arranged in parallel,
In line with these, we provide a disk double-sided polishing device that also has a conveyance means that can feed the disk surface to the polishing mechanism at each stage in a stable state without contacting it at all, and then send it to the subsequent processing stage. It is an object.

Structure/Example of the invention: Hereinafter, one embodiment of the invention will be described based on the drawings.

As shown in FIG. 1 or 2, a part of the structure wall 1 is cut out and a polishing machine 2 is installed in this part. The polishing machine 2 used in the device of the present invention has two rotating grindstones 3, 3 whose polishing surfaces face each other, and a disk to be polished is held between both the rotating grindstones 3, 3 and rotated in the same direction. The axes of these rotary grindstones 3, 3 are perpendicular to the surface of the structure wall 1. In this embodiment, two polishing machines are installed, and in the front polishing machine 2' to which the unpolished disk 9 is supplied, the planes containing the respective polishing surfaces of the two opposing rotating grindstones are always parallel. Therefore, it is suitable for cutting and polishing the disk 9, and in the polishing machine 2 located after it, the plane containing the polishing surface of one of the two rotating grindstones facing each other is always perpendicular to the axis. However, the polishing surfaces of the other rotary grindstones are set so as to be able to swing with respect to the axis to improve the ability to follow the disk surface, thereby making it easier to obtain a smooth finished surface.

A fixed bracket 11 is fixed to the structure wall 1 above each polishing machine 2 or 2', and a fixed groove wheel setter 12 is attached to the tip of the bracket so that its axis is parallel to the axis of the rotary grindstone 3. Attached. Further, lifting brackets 13 operated by a lifting mechanism 15 including a hydraulic cylinder, a slider, etc. are arranged to be located on both sides of the fixed bracket 11, and fixed groove wheels are installed at the tips of these lifting brackets 13, 13. Elevating groove wheel setters 14, 14 each having an axis parallel to the axis of the setter 12 are attached to form a disk holding section.

Furthermore, a horizontal conveyor rail 22 is installed above and below the attachment portion of the fixed bracket 11 to the structure wall 1 along the surface of the structure wall 1, and has driven rollers 21 that roll while being guided by the conveyor rail 22. Transport hook 2
Mount multiple 0s. The conveyor rail 22 consists of parallel horizontal parts and turn wheels at both ends, and the total length is an integral multiple of the distance between the axes of the rotary grinding wheels of each polishing machine. The conveyor hooks 20 are mounted at intervals equal to the distance and connected by a chain, etc., and a drive unit (not shown) is provided so that the conveyor hooks 20, 20 move with this interval as one pitch. The double-sided polishing apparatus 10 of the present invention is formed by using the main parts as , a disk holding section, and a disk transport section. Note that an unpolished disk 9 is located below the transport start end of the transport rail 22.
A disk loader 23 that can be raised and lowered to suspend the disks on the transport hook 20 is also installed below the end of the transport to move the discs 9 from the transport hook 20, and at the same time there is a disc loader 23 that can be raised and lowered to move the disc 9 from the transport hook 20 to the next step such as cleaning or surface protection. A flexible receiving section 24 is also installed.

Functions and effects of the invention: When the double-side polishing apparatus 10 having such a configuration is actually used, the unpolished disk 9 is suspended by the transport hook 20 and guided by the transport rail 22 by moving the disc loader 23 back and forth and moving up and down. transport hook 2
Due to the lateral movement of 0, the disk 9 moves to the front polishing machine 2'.
reach. As the elevating bracket 13 corresponding to the polishing machine 2' rises, the two elevating groove wheel setters 14 come into contact with the outer periphery of the disk, and when the periphery fits into the annular groove and continues to rise, the inner periphery of the disk and the conveyor It separates from the hook, and then the upper end of the outer periphery fits into the annular groove of the fixed groove wheel setter 12, and is rotatably supported at three points by two elevating groove wheel setters and one fixed groove wheel setter, and the polishing machine It is stably held between the polishing surfaces of the rotary grindstones 3, 2' and polished smoothly. Polishing at this stage can be performed so that the planes including the polishing surfaces of the opposing polishing wheels are parallel to each other, which contributes to polishing to a uniform thickness over the entire surface area of the disk. . When the grinding and polishing at this stage is completed, the rotary whetstone separates from the disk and stops, and when the elevating bracket is lowered, the disk is held by both elevating groove wheel setters and descends, and the inner peripheral edge of the disk touches the conveyor hook 20. As soon as they come into contact, both elevating groove pulley setters continue to descend and separate from the disk, and the disk 9 is suspended from the transport hook 20 again.

Next, the transport hook 20 reaches and stops directly above the rear polishing machine 2. At this time, the subsequent disk from the disk loader 23 is transferred to the subsequent transport hook 20.
The machine is suspended from the machine and reaches directly above the polishing machine 2' in the front position. The first disc that has reached the position directly above the rear polishing machine 2 and the subsequent disc that has reached the position immediately above the front polishing machine 2' behave in the same manner by the same operation, and are polished as desired.

Note that the rear polishing machine 2 does not have the facing rotary whetstone 3 like the front one, but the plane containing the polishing surface of one of the rotary whetstones is swingable about the axis, so that the disc surface This improves the ability to follow the surface of the disk, and the front and back surfaces of the disk can be precisely polished to create a smooth, flat surface.

The disk that has been finely polished by the rear polishing machine 2 is transferred to the transport hook in the same way as described above, and by the lateral movement of the transport hook, it reaches directly above the receiving part 24, where it is subjected to processing such as cleaning. After that, it is sent to the subsequent process.

Then, as the receiving part 24 advances and retreats and rises and falls, the transport hook that controls the disc turns the turn wheel and returns to the starting end via the upper stage of the transport rail 22, and the disc loader, the front polishing machine, and the rear Since the distance between the centers of the polishing machine and the receiving part as well as the winding length of the turnwheel are all set to be the same, a large number of discs move in an orderly manner through each stage and undergo a series of polishing processes, resulting in a disc shape. Discs with a predetermined surface condition can be continuously obtained from this material.

As can be seen from the above explanation, the disk double-side polishing apparatus of the present invention can perform homogeneous surface treatment continuously and efficiently, and has great industrial applicability.
