Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a conveyance device that enables the transfer of objects to be conveyed, for example, in two orthogonal directions by making rollers rotatable in a horizontal plane.

[Background technology]

In a conveyance device using rollers, there may be a request to convey the conveyed object in two directions, and in this case, conventionally, for example, as illustrated in FIG. 6, in addition to the rollers a... , rollers b facing in other directions are provided, and rollers a and rollers b are alternatively raised to support the conveyed object, but in such a device, the number of rollers a and b is In addition, the number of rollers disposed in one direction is limited, which increases the cost of the device, as the mechanism for vertical movement becomes complicated.

[Purpose of invention]

The object of the present invention is to provide a conveyance device that can solve the above-mentioned problems based on the fact that the rollers can be rotated using a rotary plate.

[Disclosure of invention]

Embodiment In FIGS. 1 to 5, the conveying device 1 of the present invention includes a substrate 3 provided with a first circular groove 2 and a second circular groove 4.
A rotary plate 5 provided with
The rotating tool A has a locking pin 7 that engages with the roller 8 and a roller holder 10 that pivotally supports the roller 8, and the rotating plate 5 is connected to a rotating machine 11. In this embodiment, the rotating tool A is located only at the left end in FIG. is supported by The substrate 3 forms the upper plate of the conveying device 1, and the first
The first circular arc groove 2 is formed around the through hole 13 provided in the substrate 3, and the first circular groove 2 has a pinching angle of about 90 degrees in this embodiment. Rotating plate 5
has a disc shape, and the through hole 13 is located in the center of the disc.
A relatively long hollow boss portion 15 is provided below which is rotatably supported via a bearing 14, and a relatively long notch portion 16 whose lower surface is open and extends vertically is provided opposite to the boss portion 15. be done. The second arcuate groove 4 is centered at the center of the boss portion 15 and has the same radius as the first arcuate groove 2, and its pinching angle is 90°.
set at the same time.

The roller receiver 10 is provided with upright pieces 2 at both ends of the base piece 19.
0 and 20 are provided in a protruding manner, and the roller 8 is pivotally supported by the upright piece 20, and the roller 8 is loosely inserted into the center of the base piece 19 through the large diameter portion 22 within the boss portion 15. A support shaft 23 is provided to protrude downward, and the substrate 19 has first and second circular arc grooves 2, which are aligned by inserting the support shaft 23 into the boss portion 15.
4 and the locking pin 7 is provided below. A retaining ring groove 25 is formed in the upper end of the locking pin 7, and the connecting piece 27 can be attached to the upper part of the locking pin 7 by the retaining ring in the retaining ring groove 25. The connecting piece 27 connects base pieces (not shown) of the rollers 9 arranged in the horizontal direction so that they can rotate together. The rotary machine 11 is a rotary actuator having an output shaft 29 that can be rotated forward and backward within a predetermined angle range, in this embodiment 180 degrees, by hydraulic pressure, pneumatic pressure, or an electric motor. A protruding pin 30 is provided, and the rotary machine 11 is attached to the back surface of the substrate 3 via an inverted hat-shaped mounting plate 31 on the upper surface of the rotating machine 11, so that the output shaft 29 can be mounted with the pin 30 inserted into the notch 16. It can be inserted into the boss 15 while doing so.

Operation: Accordingly, in the rotating tool A of the conveying device 1 of the present invention, the locking pin 7 is clamped by one end of the first circular groove 2 and one end of the second circular groove 4 due to the rotation of the rotating machine 11. 3 and the state shown in FIG. 4 in which the locking pin 7 is sandwiched between the other end of the first circular groove 2 and the other end of the second circular groove 4, as the rotating plate 5 is rotated in the forward and reverse directions. The locking pins 7 alternately change, so that the locking pins 7 are connected to the first arcuate grooves 2
By moving to both ends of the roller 8, the roller 8 is turned in two orthogonal directions, and the rotation is uniformly transmitted to the rollers 9 arranged in the horizontal direction by the connecting piece 27, and the conveyed object passing through the upper surface is rotated in two directions. It can be carried out selectively in either direction. Note that if the rotating machine 11 has a braking function and a biasing function, the locking pin 7
The rotating plate 5 can be stopped at a position where the roller 9 is clamped, and since the locking pin 7 is located apart from the support shaft, the roller 9 can be firmly restrained. In addition, in the conveying device 1 of the present invention, all the rollers 9 can be formed using the rotating tool A, and the rotating tool A can be used for only one roller 8, and the rollers 8 arranged vertically in FIG. By connecting them using the connecting piece 27, they can be configured to be operated simultaneously by one rotary machine 11, and the sandwiching angle of the first and second arcuate grooves 2, 4 can be changed. The roller 8 can be tilted not only in orthogonal directions but also in two arbitrary directions.

[Effect of idea]

In this way, the conveying device of the present invention allows each roller to rotate, so the number of rollers can be reduced by half compared to the conventional device illustrated in Figure 6, which in turn increases the number of rollers installed per length. In addition, the roller holder is useful for simplifying the structure and greatly reducing the cost of the device.
By being pinched by each end of the first circular arc groove, the roller of the roller holder can swing and rotate correctly at the angle determined by the first circular groove, and can be held at the end thereof, so that This can have many effects, such as improving holding accuracy.
