JPS61267611A - Device for retaining disc member - Google Patents

Abstract

PURPOSE:To support works different in diameter out of contact with the surface and back thereof by putting the work in an erect manner, and supporting the peripheral edge of the work at three points with V-grooved rollers which are urged by springs adapted to come up and separate from above and below in a device for retaining a magnetic disc or the like. CONSTITUTION:Cylinders 8a, 8b are contracted to separate V-grooved rollers 6a, 6b-1, 6b-2, and a disc member 2 is disposed among the V-grooved rollers 6 as shown in the drawing. Subsequently, the cylinders 8a, 8b are expanded to support the disc member among the rollers 6a, 6b by force of springs 7a, 7b. In this arrangement, even if a disc member has a different diameter, the disc member can be retained out of contact with the surface and back thereof.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a device for temporarily holding a disc-shaped member to be transported, and in particular to a device for temporarily holding a disc-shaped member to be transported, and in particular, a device for temporarily holding a disc-shaped member to be transported. This invention relates to a holding device created to hold a plate-shaped member to be transported.

[Background of the invention]

For example, when a disk-shaped member having a center hole is held and transported by a spindle, such as in the manufacturing process of a magnetic disk, it may be necessary to temporarily hold the disk-shaped member to be transported. .

FIG. 3 is an explanatory diagram of the necessity of temporary holding.

When the disc-shaped member 2 is held by the suction means provided at the tip of the spindle (A) ia, the illustrated surface 2r is easy to process and inspect, but the opposite surface 2It is difficult to process and inspect. Therefore, this is the spindle Q3)l
b, it must be held again as indicated by the phantom line 2'.

FIG. 4 is an explanatory diagram of the above-mentioned holding and converting operation.

Spindle (A) holding the disc-shaped member 2
is advanced in the direction of arrow C, and after holding the disc-shaped member 2 at the 21 position by the temporary holding means 3, the spindle (
A) l a is moved back in the direction of arrow d.

Next, the spindle [F]) 1b is advanced as shown by the arrow e, and while the disc-shaped member at the 2' position is held by suction, it is moved back as shown by the arrow f.

For such operations, it is necessary to temporarily hold the disk-shaped object in a vertical position. Moreover, the means 3 for temporarily holding the disc-shaped member requires (1) not touching the front or back surface of the disc-shaped member; It would be desirable to be able to adapt the system without requiring separate adjustments.

[Purpose of the invention]

The present invention has been made in response to the above-mentioned demands, and is capable of temporarily holding a disk-shaped member to be transported without touching the front or back surface thereof, and furthermore, the present invention The purpose of the present invention is to provide a holding device that can immediately adapt to changes in the temperature.

[Summary of the invention]

In order to achieve the above object, the disc holding device of the present invention includes:
A guide member installed vertically, a pair of upper and lower slide bases guided by the guide member, one groove roller pivotally supported on the upper slide base of the pair of slide bases, and the two V-groove rollers pivotally supported on the lower slide base of a pair of slide bases;
a spring means for biasing the pair of slide bases in a direction toward each other; a means for locking the vertical movement of the lower slide base; and a cylinder means for driving the pair of slide bases in a direction to move them apart from each other. and the three V-groove rollers are arranged along the same plane with their center axes parallel to each other, and the disk-shaped conveyed member is held between the groove bottoms of these three V-groove rollers. It is characterized by being configured so that it can be used.

[Embodiments of the invention]

Next, one embodiment of the present invention will be described with reference to FIGS. 1 and 2.

FIG. 1 is a partial sectional view showing one embodiment of the present invention, and FIG. 2 is a sectional view taken along the line i-m in FIG.

xx′ shown in FIG. 2 is a spindle (not shown in this figure, but shown in FIGS.
This is the central axis of la, lb shown in the figure.

The axis x-x' is perpendicular to the intersection point 0 of the axes Y-Y' and Y-Y' shown in FIG. That is, in FIG.
-x' passes through point O and is perpendicular to the plane of the paper.

A guide post 4 is installed perpendicular to the axis x-x'. When carrying out the present invention, the center axis X-X' of the spindle is installed horizontally, and the guide member (the guide column 4 in this example
) is conveniently installed perpendicular to the earth, but it is also possible to install the spindle and guide member by rotating them relative to the state shown in FIG. 1 while maintaining their perpendicularity. In the present invention, the terms "upward" and "downward" refer to directions when the guide member is installed perpendicularly to the earth.

The guide member 4 slidably supports a pair of upper and lower slide bases 5a and 5b.

Roller support arms 5a-1, 5b-1 and drive arms 5a-2, 5b-2 are fixed to the slide bases 5a+5b, respectively.

The V-groove roller 6a is attached to the roller support arm 5a-1.
#) grooved roller 5b-1. 6b-2 is pivotally supported. Specifically, these three rollers are supported by shafts in the X-axis direction aligned with the Y-Z plane.

Arms 4a and 4b are fixed to the guide column 4, and a spring 7 is installed between the arm 4a and the slide base 5a.
A is compressed and interposed, and a spring 7b is compressed and interposed between the arm 4b and the slide base 5b to urge both slide bases 5a and 5b toward each other.

The cylinder 8a has a structure capable of driving the slide base 5a upward via the arm 5a-2, and the cylinder 8b has a structure capable of driving the slide base 5b downward via the arm 5b-2. In this manner, the present embodiment is provided with cylinder means for driving the pair of slide bases 5a, 5b in the direction of separating them from each other.

As shown by the imaginary line in Fig. 1 and the cross section shown in Fig. 2,
A means for locking the sliding movement of the slide base 5b in two axial directions is provided.

A pair of cylinders 10a and 10b are installed facing each other by a bracket 9 via an arm 5b-1. Pressing pads lla and llb are fixed to the tips of the cylinder rods of the pair of cylinders 10a and 10b, and both cylinders II
” When 10a and 10b are extended, a pair of suppression pads 11a is formed.

11b is configured to pinch the arm 5b-1 and brake its movement.

In order to temporarily hold the disc-shaped member 2 with the device of this embodiment, the cylinders f3a and gb are contracted to move the V-groove roller 6a upward and the groove rollers 5b-w and 5b-z downward. The disc-shaped member 2 is supported at the position shown in the figure, and the spindle (
3, 4)), cylinders 8a, g
Stretch b.

Then, the slide bases 5a and 5b are biased by the springs 7a and 7b, respectively, and approach each other, and the V-groove rollers 6a and 5b-1 and 5b-1 and 5b, which are pivotally supported on these slide bases,
The disc-shaped member 2 is held between b-2.

When the disc-shaped member 2 is clamped as described above, even if the diameter of the disc-shaped member 2 changes slightly, three V* flora a,
6b-1 and 5b-2 can be adapted to abut and clamp. In this state, the pair of cylinders 10a.

When the arms 5b-1 are extended and the arms 5b-1 are clamped, the disc-shaped member 2 is held at the illustrated position (FIG. 1) even if the spindle releases the disc-shaped member 2 from being held by the spindle.

After changing the support of the disc-shaped member 2 by the spindle,
When the pair of cylinders 10allOb% and the pair of cylinders 8a and sb are contracted, three V-groove rollers 6a,
6b-1 and 5b-2 are separated from the disc-shaped member 2 and release their holding.

〔Effect of the invention〕

As described in detail above, according to the holding device of the present invention, it is possible to temporarily hold a disc-shaped member to be transported without touching the front or back surface of the disc-shaped member. It has an excellent practical effect of being able to adapt immediately even if the diameter changes.
