Here, the work W transfer device 11 of the present embodiment includes a discharge unit 16 located downstream of the accommodating unit 15 of the carry-out unit 13. Since the shape of the accommodating portion 15 is a groove shape having openings on the upstream side and the downstream side, the work W carried out from the conveyor 12 can pass through the accommodating portion 15 toward the discharging portion 16. Further, in the groove shape of the accommodating portion 15, the upstream end portion, that is, the end portion on the conveyor 12 side is formed so as to be wider than the other portions. As a result, the work W carried out from the conveyor 12 can be easily inserted into the accommodating portion 15. The carry-out unit 13 can be formed of, for example, a resin pallet.

The work W transport device moves the carry-out portion 13 in a direction orthogonal to the transport direction of the conveyor 12, that is, along the Y-axis direction, so that the work W is sequentially accommodated in the plurality of accommodating portions 15. A positioning mechanism 17 for positioning the 15 is provided.

In the guide member 22, the distance between the first guide portion 22a and the second guide portion 22b at the upstream end in the transport direction is formed wider than the other portions. As a result, the work W conveyed by the conveyor 12 can easily enter between the first guide portion 22a and the second guide portion 22b. On the other hand, in the guide member 22, the distance between the first guide portion 22a and the second guide portion 22b on the downstream side in the transport direction is larger than the distance between the first guide portion 22a and the second guide portion 22b at the upstream end. Close to the diameter of. Thereby, the positioning accuracy of the work W in the width direction on the conveyor 12 can be improved. The guide member 22 is fixed by a support (not shown) so as to be located above the conveyor 12 with a slight distance from the transport surface so as not to come into contact with the conveyor 12. The guide member 22 is made of any material having durability to withstand contact with the work W, such as metal or synthetic resin.

Here, the accommodating portion 15 of the carrying-out portion 13 has an opening that allows the work W to pass through the discharging portion 16 as described above. Therefore, by moving the second pressing head 20b of the second pressing member 20 straight toward the downstream side, the defective work Wd can be discharged from the accommodating portion 15 of the carrying-out portion 13 to the discharging portion 16. At this time, the first pressing head 19b of the first pressing member 19 is also moved until the work W is accommodated in the accommodating portion 15 of the carry-out portion 13 as described above.

After the second operation is completed, in the carry-out step, the second pressing member 20 is retracted by raising the second pressing head 20b of the second pressing member 20 and retracting the second pressing member 20 toward the upstream side of the conveyor 12. Then, in the carry-out process, the same second operation is repeated for the work Wd accommodated in the accommodating portion 15 based on the determination result of the determination step. That is, the second pressing member 20 has a start position at which the second pressing head 20b can be inserted upstream of the work W housed in the accommodating portion 15 and a work W ejected portion 16 based on the determination result of the determination process. It operates so as to reciprocate with the discharge position.

That is, the first pressing member 19 of the moving mechanism 14 moves the work W to the accommodating portion 15 by pressing the end surface on the upstream side of the work W located on the most downstream side on the conveyor 12. Further, the first pressing member 19 of the moving mechanism 14 of the present embodiment is configured to be able to press the work W so as to pass through the accommodating portion 15 of the carrying-out portion 13.

In the carry-out step of the work W transfer method, the work W determined to be a non-defective product in the determination step is pressed by the first pressing member 19 to perform the first operation of moving the work W to the accommodating portion 15. Further, as shown in FIGS. 17 and 18, in the unloading process of the work W transfer method, the work Wd determined to be defective in the determination process is pressed by the first pressing member 19 to form a conveyor. A second operation is performed in which the accommodating unit 15 is passed from above the 12 and discharged to the discharging unit 16.

As described above, in the second embodiment, since the first operation and the second operation are performed by the common first pressing member 19, it is possible to simplify the moving mechanism 14 of the work W transfer device 11. Will be.

(Change example)
This embodiment can be modified and implemented as follows. The present embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

The work W may be continuously conveyed by continuously operating the conveyor 12, or the work W on the conveyor 12 may be temporarily stopped by intermittently operating the conveyor 12. Further, when the conveyor 12 is continuously operated, the transport speed may be changed. However, from the viewpoint of increasing the transfer efficiency of the work W, it is preferable to continuously operate the conveyor 12.

The shape and dimensions of the first pressing head 19b of the first pressing member 19 and the second pressing head 20b of the second pressing member 20 can be appropriately changed according to, for example, the shape and dimensions of the end face of the work W.

-In the method of transferring the work W, the determination step may be omitted.
-The shape of the accommodating portion 15 in the carrying-out portion 13 may be, for example, a shape other than the groove shape. The accommodating portion 15 may be an accommodating portion 15 that collectively accommodates a plurality of work Ws.

-In the method of transferring the work W, for example, when the determination step is omitted, the downstream side of the groove-shaped accommodating portion 15 may be composed of a wall portion without opening.
-In the method of transferring the work W, the transfer process may be performed without using the guide member 22. Further, the guide portion of either the first guide portion 22a or the second guide portion 22b of the guide member 22 may be omitted.

The guide member 22 is arranged so as to guide the work W on the downstream portion of the conveyor 12, but for example, the position of the guide member 22 is appropriately positioned so as to guide the work W on the upstream portion of the conveyor 12. Can be changed.

-In the transfer process, the work W may be conveyed by arranging the flat surface of the work W to face upward and the curved surface of the work W so as to overlap the transfer surface of the conveyor 12.
-The overall shape of the work W is not limited to a solid rod shape, and may be tubular, for example. The cross-sectional shape of the work W may be a circular shape, an elliptical shape, or the like, or may be a polygonal shape.
