[C−1]のタイミングである。First, as an initial state, the cloth holders (4) and (5) are in the first position.
At the position shown in the figure, the lid (4g) is closed, the lid (5g) is open, the cylinders (13) and (21) are ON, and the cloth retainers (4) and (5) are engaged respectively. The arms (7), (8) and (15), (16) are fixed to the movable table (6). In this state, when the worker sets the sewn cloth (34) in the second cloth holder (5) and closes the lid (5g), the lid (5g) is attached to the metal piece (33). ) Is a proximity switch (3
1) The contact of the proximity switch (31) is turned on because it comes to the top. This is the timing of [A-1] shown in FIG. Then, when a certain time elapses and the timing of [B-1] is reached, the air cylinder (27) is actuated, the movable table (6) moves along the rail (23), and the second cloth retainer is moved. When (5) reaches the position where the first cloth retainer (4) was, the cylinder (21) is turned off at this point, and the blocks (5c) and (5d) move to the engaging arms (15) and (16). ) Is released, and the second cloth holder (5) is released from the movable table (6). At the same time, the presser arm (2) of the drive is turned on, and the positioning pins (2a) and (2b) are inserted into the blocks (5a) and (5b).
The second cloth retainer (5) is connected to the presser arm (2). At this time, a cylinder (not shown) for opening the lid (4g) of the first cloth retainer (4) is driven, and its shaft end is (4g).
The lid (4g) is opened with the hinges (4e) and (4f) as fulcrums, and the cloth (34) that has been sewn can be taken out. This state is the timing [C-1] in FIG.

連結される。At this time, when the presser arm (2) for moving the cloth holder is driven, the second cloth holder (5) is pressed against the slide plate (3) and is slid back and forth and left and right according to the programmed data. At the same time, the needle of the sewing machine head (1a) is driven to sew the cloth (34) held by the second cloth holder (5). During this time, the worker sets the cloth (34) for the next sewn product on the first cloth holder (4) and closes the lid (4g). At this time, the proximity switch (not shown) set in the sliding plate hole (3f) works in the same manner as described above and is turned on. This is the timing of [D-1] shown in FIG. Then, when the sewing of the cloth (34) set on the second cloth retainer (5) is completed, the sewing machine presser arm (2) is turned off.
And rises to open the second cloth holder (5). At the same time, the cylinder (21) is turned on and the second cloth holder (5) is fixed to the moving table (6). This is [E in Figure 5
-1] timing. At this time, the cylinder (27) is OF
F, the movable table (6) moves along the rail (23) to the state shown in FIG. 1, and the first cloth holder (4) reaches the position where the second cloth holder (5) was located. Then the cylinder (13) is OF
It becomes F, and the first cloth retainer (4) is opened. At the same time, the presser arm (2) is turned on and is connected to the first cloth holder (4).

が繰り返される。At the same time, in the second cloth retainer (5), the air cylinder (29) works and the lid (5g) is opened as shown in FIG. 3, and the cloth (34) which has been sewn can be taken out. This is the timing of [F-1] shown in FIG. Then, the needle of the sewing machine head (1a) is driven to sew the cloth (34) held by the first cloth holder (4). Meanwhile, the second cloth retainer (5) is sewn to the next cloth (34).
And close the lid (5g). At this time, the proximity switch (31) set in the sliding plate hole (3g) works in the same manner as described above, and is turned on. This is the timing [A-2] shown in FIG. The same cycle is repeated thereafter.

果がある。[Effects of the Invention] As described above, according to the present invention, the means for holding the sewn product is constituted by an independent single cloth retainer, and a plurality of such fabric retainers are arranged so as to be alternately supplied to the sewing machine drive portion. Since the cloth holder is automatically opened with respect to the cloth holder that holds the completed cloth, it is easy to attach and detach the sewn product. Further, while the sewing machine is sewing a sewing product in one cloth retainer, the next sewing product can be set in another cloth retainer, which shortens the time for attaching and detaching the sewing product and reduces the production time. The property is improved. Further, since the cloth holder is also moved on a flat surface, there is an effect that the structure of the conveying device is simple and the cost can be reduced.
