[Detailed Description of the Invention] A. Object of the Invention (1) Industrial Application Field The present invention relates to a transfer device for supplying and discharging workpieces to and from a processing station, and in particular, to a transfer device for supplying and discharging workpieces to and from a processing station. and a machining transfer device for transferring workpieces to and from a delivery conveyor. C》Prior art The transfer type machine tool proposed earlier by the present applicant is equipped with at least two machine tools and a rotary transfer loader in a processing station, and the workpieces supplied from the input conveyor are transferred by the transfer loader. The machine is conveyed sequentially from the first machine tool to the second machine tool to the delivery conveyor, during which multiple machining steps are completed (Special Publication No. 58-
(See Publication No. 37108). (S) Problems to be Solved by the Invention The transfer type machine tool described above can process a large number of workpieces in a short time, but when processing an even larger number of workpieces, it is necessary to use multiple machining machines. It is necessary to have a In such cases, it is conceivable to arrange multiple processing stations in series along one conveyor and process workpieces in parallel at each processing station. However, if such a machining station arrangement is adopted, the downstream machining station is supplied with a mixture of unprocessed workpieces and processed workpieces processed at the upstream machining station. The problem is that it requires specialized equipment. Another method is to arrange a plurality of processing stations in parallel between an input conveyor and an output conveyor, connect a plurality of input conveyors branched from the input conveyor to each processing station, and extend from these processing stations. It is also possible to merge the delivery conveyor with the delivery conveyor, thereby avoiding mixing of unprocessed workpieces and processed workpieces. However, if such a layout is adopted, in order to monitor the processing status of the processing station from the conveyor side for safety reasons, it is necessary to assign a separate worker to each processing station, which is extremely uneconomical. There are problems. The present invention was made in view of the above-mentioned circumstances, and it is possible to supply and discharge unprocessed workpieces and processed workpieces to two processing stations without mixing them, and moreover, it is possible to perform the work by one person. The purpose of this invention is to provide a transfer device for machining that allows a person to simultaneously monitor the machining status of both machining stations. B. Structure of the Invention (1) Means for Solving the Problems In order to achieve the above object, the machining transfer device of the present invention includes a first machining station and a second machining station that perform the same machining on a workpiece, and a second machining station that performs the same machining on a workpiece. a first carry-in conveyor and a second carry-out conveyor that supply and discharge workpieces to and from the first processing station; a 211th person conveyor and a second carry-out conveyor that supply and discharge workpieces to and from the second processing station; In a transfer device comprising a common work input conveyor connected to both carry-in conveyors and a common work discharge conveyor connected to both carry-in conveyors, a conveyance path closed by the pair of carry-in conveyors and the pair of carry-out conveyors is provided. form,
The present invention is characterized in that both processing stations are disposed facing each other on the outside of this conveyance path.

22, and joins the delivery conveyor 11 at the merging section P2. At this time, the workpiece W on the first* output conveyor Cl2 is waiting in contact with the lifting stopper 12, and the workpiece W on the second output conveyor C22 is waiting.
After passing, the elevating stopper l2 is lowered and the pusher 17 is driven by the rodless cylinder l6 of the extrusion device 13, whereby the ejector is pushed out onto the delivery conveyor 11. When processing the workpiece W as described above, the worker is located in the work space A and operates two processing stations Sl.
, the machining status in S2 is transferred to conveyors C11 and C21.
and unloading conveyor C12. It is possible to simultaneously monitor from inside the C22. Although the embodiments of the present invention have been described in detail above, the present invention is not limited to the above embodiments, and without departing from the scope of the invention described in the claims.
Various small design changes can be made. For example, input conveyor 1, output conveyor 11, carry-in conveyor C1
1 and C21 and the discharge conveyors C12 and C22 are not necessarily roller conveyors, and a part or the front part thereof can be replaced with another conveyor such as a chain conveyor or a belt conveyor. In addition, machine tools MCII to M installed in each processing station S1, S2
The number of C22s does not have to be two; it may be one or three or more. Furthermore, the shape of the conveyance path does not necessarily have to be rectangular; for example, the conveyance path may be formed in an elliptical shape, with a branching part and a confluence part located at both ends of the long sleeve, and two ellipses at both ends of the short axis. It is also possible to arrange processing stations facing each other. C. Effects of the Invention According to the transfer device for machining of the present invention described above,
The workpieces distributed from the input conveyor to the first and second carry-in conveyors are processed at two processing stations, and the processed workpieces are merged onto the discharge conveyor via the first and second carry-out conveyors, so that unprocessed workpieces are Workpieces and processed workpieces do not mix together on the conveyance path. Moreover,
Since the two processing stations are placed facing each other on the outside of the closed conveyance path, one
The machining status of both machining stations can be monitored simultaneously by human workers. Since this monitoring is performed from the conveyor side at both processing stations, worker safety can be ensured. In addition, when forming the conveyance path, the sum of the lengths of the first carry-in conveyor and the 11L carry-out conveyor connected to the first processing station, and the length of the 2L carry-out conveyor connected to the second processing station are determined.
By setting the sum of the lengths of the I-person conveyor and the 2-I unloading conveyor to be the same, the time it takes for the workpieces distributed to both processing stations to join together becomes the same, making it possible to do the joining smoothly. ..
