Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a stud bolt direction alignment device.

That is, the present invention determines the direction of the stud bolt, and
The rotary outer drum, which is driven by any means, is rotatably inserted into the driven rotating inner drum that is supported by a fixed shaft, and the fixed shaft and the rotating outer drum are rotatably inserted. A through hole passing through the inner drum and the rotating outer drum is formed, and a needle rod with its tip facing inward is supported and fixed in one hole of the rotating outer drum constituting the through hole.

The configuration of the present invention will be explained below with reference to the drawings.

In Figures 1 to 5, 1 is the fixed shaft, 2 is the fixed shaft 1
This is a driven rotating inner drum that is pivotally supported by a rotor, which has an annular groove 3 at a predetermined circumferential position on its outer circumferential surface, and whose movement in the axial direction is restricted by side plates 4 and 5.

An outer rotating drum 6 driven by an arbitrary means is rotatably fitted into the inner rotating drum 2, and a part of the outer drum 6 is engaged with a stepped surface T formed on the outer peripheral surface of the side plate 5.

Then, a through hole 8 is formed to pass through both the rotating drums 2.6 and the fixed shaft 1 along the left-right symmetrical axes of the circular cross-sections, and the hole diameter is as shown in FIG. 4, for example. It is determined according to the diameter of the stud bolt 9 so that the stud bolt 9 can easily pass through the through hole 8.

One hole 8' of the rotary outer drum 6 that constitutes the through hole 8
A member 10 fitted into the hole 8' is fixed with a screw 11.

This member 10 has its inner and outer surfaces flush with the circumferential surface of the outer rotating drum 60, and has a hole 13 that communicates with a recess 12 formed on the inner surface.

Then, insert the needle rod 14 into the hole 13 of the member 10 and screw the screw 1.
5, and its tip 14' is exposed in the recess 12 and positioned at the center of the through hole 8, and when the outer rotating drum 60 rotates, the tip 14' fits into the annular groove 3 of the inner rotating drum 2. Follow the instructions.

Next, the operation of the present invention will be explained.

When the stud bolt 9 shown in FIG. 6 is in a position with the driver groove 9' facing upward as shown in FIG.
When the stud bolt 9 falls further into the through hole 8, the end face 9'' of the stud bolt 9 comes into contact with the tip 14' of the needle rod 14 and stops.

Thereafter, as shown in FIG. 3, the rotary outer drum 6 is rotated 180 degrees by any means.

Then, the end face 9'' of the stud bolt 9 is located inward from the outer circumferential surface of the rotating inner drum 2, and the upper portion thereof protrudes toward the fixed shaft 1 side from the inner circumferential direction of the rotating inner drum 2.
The rotating inner drum 2 is locked and does not rotate, and the tip 14' of the needle rod 14 comes off the end face 9'' of the stud bolt 9.
While following the annular groove 3 of the rotating inner drum 2, only the rotating outer drum 6 rotates, and during the rotation, the stud bolt 9 is rotated from the original position with its end surface 9'' in contact with the inner circumferential direction of the rotating outer drum 6. Stopped at the stop position (~.

In this way, the paper rotates 180 degrees and the through hole 8 at the top
As shown in FIG. 5, the opening 8'' moves to a lower symmetrical position about the fixed shaft 1, and forms the through hole 8 again.

As a result, the stud bolt 9 is dropped and discharged to the outside with the driver groove 9' facing upward.

Next, when the stud bolt 9 falls through the upper opening 8'' with the driver groove 9' facing downward as shown in FIG. The driver groove 9' and the driver groove 9' fit into the recess 12 and the tip 14' of the needle rod 14, respectively.

Thereafter, the rotary outer drum 6 is rotated 180 degrees by any means.

Then, the end face 9'' of the stud bolt 9 is connected to the rotating inner drum 2.
As shown in FIG. Rotates the paper 180 degrees together with drum 6.

As a result, the stud bolt 9 moves to an upper symmetrical position around the fixed shaft 1 by the rotation of the rotating inner drum 20,
The driver groove 9' faces upward.

At the same time, the opening 8'' of the through hole 8 at the top moves to a symmetrical position at the bottom about the fixed axis, forming the through hole 8 again.

As a result, the stud bolt 9 falls within the through hole 8 with the driver groove 9' facing upward and is discharged to the outside.

Therefore, even if the initial advancing posture of the stud bolt 9 into the through hole 8 is different, the stud bolt 9 can move the outer rotating drum 6 in one direction.
By rotating the paper 80 degrees, when the paper is discharged from the through hole 8, it is always in a constant posture, that is, with the driver groove 9' facing upward.

Then, when the stud bolt 9 is dropped and ejected, the outer rotating drum 6 is rotated again by any means and the second
The device returns to its original state as shown in FIG. 4 and repeats the above-mentioned operation again.

Incidentally, in the above explanation, a stud bolt was taken as an example, but the present invention can be widely applied to bolts and bottles.

In particular, when the shape (diameter) changes significantly, it can be done more easily and reliably.

As explained above, this invention consists of a central fixed shaft that is supported horizontally and has a through hole in the vertical direction perpendicular to the axis, and a stud bolt that is rotatably fitted onto the central fixed shaft. having a through hole perpendicular to the axis;
and a rotating inner drum having an annular groove formed on its outer circumferential surface passing through the center of the through hole, and a rotating inner drum rotatably fitted onto the rotating inner drum and having a through hole perpendicular to the axis; A plug member is provided with a concave portion formed at the inner end to receive one end of the stud bolt, and a needle rod whose tip protrudes from the annular groove of the rotating inner drum is provided in the center of the plug member, and is driven as appropriate. It consists of a rotating external drum that is driven to rotate by 180 degrees by a means, and one stud bolt having a driver groove at one end and a flat surface at the other end is aligned in the same direction for every half rotation of the rotating external drum. I decided to send it out,
It has the following effects.

That is, when the stud bolt is supplied with its driver groove facing upward (in the positive direction), the head of the stud bolt can be pushed up into the through hole of the central fixed shaft by the needle rod, and as a result, it is prevented from rotating. When the drum rotates half a rotation, the head of the stud bolt fits into the center fixed shaft to reliably prevent the rotation of the inner drum from co-rotating, and no other complicated anti-co-rotation means are required.

In addition, when the stud bolt is supplied with its driver groove facing downward (in the opposite direction), the lower end of the stud bolt fits into the recess of the plug member and sinks. It's out of place!
In addition, the circumference of the lower end of the stud bolt is aligned with the inner circumferential surface of the concave portion of the plug member, so that when the outer rotating drum rotates half a rotation, the rotary direction drum is rotated half a rotation as a unit, and the stud bolt is turned in the forward direction. In this case, no rotational force is applied to the tip of the needle rod, so there is no chance of the needle rod breaking or being bent.
