Means for Solving the Problem The present invention mounts a pair of transfer rails facing each other at regular intervals and at least a part of which is formed in a double spiral shape, and a work transferred by the pair of transfer rails. A work holding member, guide parts provided on both sides of the work holding member near one end in the traveling direction, and guided by the transport rail, and rotatably provided on the other end side in the traveling direction of the work holding member. And a supporting member whose both sides are guided by the pair of transport rails.

F. Action When the support member or work holding member is moved in the axial direction of the transport rail and reaches the double spiral portion, the guide parts provided on both sides of the work holding member near the one end in the traveling direction are supported by the transport rail. , The other end is rotatably supported by the support member, and the guide portions on both sides of the support member are guided by the transport rails, so that the work holding member and the support member are each a double spiral portion. Rotate about an axis while moving along. At this time, since the guide portions on both sides of the work holding member near the one end in the traveling direction are guided by the transport rail and the other end is supported by the supporting member, the work state member does not rotate in the traveling direction. .

G. Embodiment Hereinafter, one embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view of a rotary conveyance device.
In the figure, a rotary transfer device 1 includes a pair of transfer rails 2, a work holding member 4 which is guided by the pair of transfer rails 2 and mounts a work 3, and a work holding member 4 which is rotatably supported and guided by the transfer rail 2. And a supporting member 5 to be formed.

Grooves having a U-shaped cross section are formed in the pair of transport rails 2 and are arranged at regular intervals or facing each other. This transport rail 2 has linear portions 2a and 2c on both sides in the traveling direction.
And the middle part thereof is a double spiral portion 2b. This double spiral section 2b is 180 ° around the axis
It has a rotated structure.

The work holding member 4 is formed in a rectangular frame shape, and locking members 6 projecting inside the frame portion 4a are rotatably attached to corresponding surfaces on both sides thereof. These locking members 6 are for attaching the work 3 arranged inside the frame portion 4a or a pallet for fixing the work to the work holding member 4. The work 3 may be planar or three-dimensional. This work holding member 4
A shaft-shaped guide portion 4b is formed so as to project on both sides near one end in the traveling direction of the above, and is slidably fitted in the groove of the pair of the transport rails 2.

The support member 5 is formed in a rod shape, and rotatably supports the center of the other end of the work holding member 4 in the traveling direction via a rotary shaft 7. Shaft-shaped guide portions 5b are provided at both ends of the support member 5, and the guide portions 5b are slidably fitted in the grooves of the pair of transport rails 2.

Next, the operation of the above embodiment will be described with reference to FIGS.

FIG. 2 is a schematic diagram in which the work holding member 4 and the support member 5 are marked with “◯”, “Δ”, and “□” so that their relative positions can be easily understood. FIGS. 3 and 4 show a state in which both the schematic work holding member 4 and the support member 5 are positioned on the linear portion 2a of the transport rail 2, and FIG. 3 is a plan view and FIG. The figure is a front view of FIG. As shown in FIGS. 3 and 4, when both the work holding member 4 and the support member 5 are guided by the linear portion 2a of the transport rail 2, both of them are located in the same plane, Both surfaces are located above.

5 and 6 show that the support member 5 is still a straight portion 2a.
3A and 3B are a plan view and a front view showing a state in which the work holding member 4 has been moved to the double spiral portion 2b. 5 and 6, since the work holding member 4 is rotatably supported by the support member 5 and is guided by the double-spiral portion 2b of the transport rail 2, It moves in the traveling direction along with and rotates about the axis of this traveling direction. At this time, the guide portions 4b provided on both sides of the work holding member 4 toward the one end in the traveling direction are slidably fitted to the transport rail 2, and the center of the other end of the work holding member 4 is connected via the rotary shaft 7. Since the work holding member 4 is rotatably supported by the support member 5, the work holding member 4 is prevented from rotating in a rotation direction (for example, a traveling direction) other than a direction perpendicular to the traveling direction.

7 and 8 show that the work holding member 4 is a linear portion.
2C is a plan view and a front view showing a state where the support member 5 has reached the double spiral portion 2b and has moved to the double spiral portion 2b. In FIGS. 7 and 8, the work holding member 4 is further rotated in the same manner as described above and is located at a position of 180 ° from the initial state, and the support member 5 has a double spiral shape centered on the rotation shaft 7. It has rotated 90 degrees from the initial state.

9 and 10 are a plan view and a front view showing a state in which the work holding member 4 and the supporting member 5 are further moved so that they are both positioned in the linear portion 2c. 180 ° from the initial state with the holding member 4
It is rotating, that is, inverting. In this way, the work holding member 4 and the support member 5 are rotated by a predetermined angle while being conveyed while continuously performing their rotational movement while changing the relative angle.

According to the above-described embodiment, since the rotary transport device is configured to rotate while transporting, the work is rotated (reversed) in a consistent flow work, and the work on the side surface and the back surface such as machining, assembly, and inspection is rotationally repaired. It can be performed without using tools, and there is an effect that the facility can be simplified, workability and work efficiency can be improved, and cost can be reduced.

In the above embodiment, the rotation angle of the work can be arbitrarily changed by changing the winding of the double spiral portion. In addition, the linear portion and the double spiral portion can be arbitrarily combined, and the winding direction of the double spiral can be reversed, so that they can be conveyed and variously rotated. Further, the pair of transport rails in the linear portion may be changed only in the height direction, or the transport rail may be formed so that the axis line of the double spiral is curved.

H. Advantages of the Invention As is clear from the above description, the present invention has a pair of transport rails, at least a part of which are formed in a double spiral shape and arranged at regular intervals, to the one end of the work holding member in the traveling direction. By providing a support member that guides both sides of the work holding member and rotatably supports the other end of the work holding member and both sides of which are guided by the transport rail, the work holding member and the support member have a double spiral shape.
