Description

[Detailed description of the invention] The present invention relates to a transfer device that transfers objects between conveyors, and in particular, to smoothly transfer objects between conveyors arranged orthogonally to each other. The present invention relates to a transfer device capable of

For transferring objects between conveyors arranged perpendicularly to each other in this way,
Conventionally, as shown in Japanese Utility Model Application Publication No. 55-50066, a distance of 45 mm was applied between the ends of both conveyors.
There has been a system in which a plurality of rollers are arranged at an angle of 100 degrees to change the conveyance direction of the conveyed object, but this method has the disadvantage that the direction change of the conveyed object lacks smoothness. Furthermore, conventionally, a turntable was arranged between the ends of both conveyors, but this method could only be applied to a combination of a single conveyor, and therefore could not improve conveyance efficiency.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a transfer device that solves the problems of the prior art, has high transport efficiency, and can smoothly change the direction of transported objects.

In order to achieve the above object, the present invention is designed to convey objects on a plurality of upstream conveyors that are arranged in parallel so that they can be operated intermittently, so that they are perpendicular to each upstream conveyor so that they are close to the ends of these upstream conveyors. In a transfer device for transferring onto a downstream conveyor, a first rotating shaft and a second rotating shaft rotate in synchronization in opposite directions between a pair of adjacent upstream conveyors. are installed concentrically in the vertical direction, and an arm is cantilevered at the upper end of each shaft to move in a substantially horizontal plane and transfer the conveyed items on the upstream conveyor to the downstream conveyor. A roller is installed at the tip, while a single rotating shaft that can rotate in both directions is installed vertically on the outside of the upstream conveyor at the farthest end. An arm for transferring the conveyed items on the upstream conveyor onto the downstream conveyor is supported on a cantilever, and a roller is mounted on the tip of this arm, and the arm is mounted on the tip of each upstream conveyor and rotates in opposite directions. Some apparatuses are characterized in that rollers at the tips of a pair of arms that rotate in synchronization with the direction contact the back surface of the conveyed object and push it onto the downstream conveyor.

The present invention will be explained below with reference to embodiments shown in the drawings.

Fig. 1 shows a state in which a specimen 1 of a material testing machine is transported as an object as an example of the present invention, and the upstream side of a plurality of specimens (three in the example) arranged in parallel for intermittent operation is shown in Fig. 1. Conveyor 2A, 2B, 2
At the end of C (hereinafter collectively referred to as 2), a downstream conveyor 3 is disposed orthogonally to and close to each upstream conveyor 2, and each conveyor 2, 3 is provided by a conveying means (not shown). The specimen 1 is transported in the directions of the arrows.

A pair of adjacent upstream conveyors 2A and 2B, 2B
and 2C are each provided with a guide tube 4 shown in detail in Fig. 2.
are arranged in the vertical direction, and inside each guide tube 4, a cylindrical first rotating shaft 5 having a length protruding from the upper and lower ends of the guide tube 4 is rotatably supported via bearings 6, 6. It is arranged. Further, within the first rotating shaft 5, a second rotating shaft 7 having a length protruding from the upper and lower ends of the first rotating shaft 5 is rotatably disposed via bearings 6, 6. The first rotating shaft 5 and the second rotating shaft
At the upper end of the rotating shaft 7, there is an arm 8A or 8B that faces each of the conveyors 2 and 3 and is used to transfer the specimen 1 on the upstream conveyor 2 onto the downstream conveyor 3.
A roller 9 is rotatably supported at the tip of each arm 8A, 8B. Also,
A pulley 10A or 10B is attached to the lower end of each rotating shaft 5, 7.
0B is connected to a drive device (not shown), and is connected to a pulley 10A of the first rotating shaft 5 and a pulley 10 of the second rotating shaft 7.
B are rotated synchronously and reversibly in mutually opposite directions.

Returning to FIG. 1, a guide tube 4 is disposed vertically on the outside of the upstream conveyors 2A, 2C located at both ends, and a rotating shaft 11 of a length protruding from the upper and lower ends of this guide tube 4. is rotatably arranged via a bearing (not shown). An arm 8C is protruded from the upper end of the rotary shaft 11, and extends over the conveyors 2 and 3 for transferring the specimen 1 on the upstream conveyor 2 onto the downstream conveyor 3. A roller 9 is rotatably supported at the tip of 8C. Further, a pulley (not shown) is attached to the lower end of the rotating shaft 11, and this pulley is connected to the drive device so that it can be rotated reversibly.

Therefore, a pair of arms 8C and 8A, 8B and 8B, 8 per one upstream conveyor 2
A and 8C will correspond.

In addition, near the end of the upstream conveyor 2,
An optical sensor (not shown) is provided to detect when the specimen 1 approaches this end and drive the arm drive device.

Next, the operation of the embodiment described above will be explained.

Each arm 8 is on standby parallel to the conveying direction of the upstream conveyor 2, with the roller 9 at the tip facing upstream of the upstream conveyor 2. and,
When a sensor (not shown) detects the presence of the specimen 1 on the upstream conveyor 2, each arm 8 is rotated by the drive of the drive device, and the two arms 8 are rotated synchronously in opposite directions relative to one specimen 1. The three arms 8C and 8A, 8B and 8B, 8A and 8C abut against the back surface of the specimen 1, and as the rollers 9 rotate freely, the specimen 1 is transferred from each upstream conveyor 2 to the downstream conveyor 3. During this time, the conveyor 2 is temporarily stopped. When this transfer is completed, each arm 8 rotates in the opposite direction and returns to the above-mentioned standby position in preparation for the transfer of the next specimen 1.

As explained above, the transfer device according to the present invention includes a pair of rotating shafts that are coaxially arranged and can rotate synchronously in mutually opposite directions between a pair of adjacent upstream conveyors, and One rotating shaft is installed on the outside of the upstream conveyor located at both ends, and an arm for transferring the transported object is installed protruding from each rotating shaft, and the arm is rotated to move the transported object onto the downstream conveyor. Since it is pushed out, a plurality of objects can be regularly transferred from a plurality of upstream conveyors to a single downstream conveyor at the same time, and conveyance efficiency is high, and direction changes can be easily performed. Furthermore, since the first rotation shaft and the second rotation shaft are arranged concentrically, the installation space can be reduced.
