The rear locking member 59b is used in a paired state with a vertical gap, and a tip end 59f that swings supported by a fulcrum 59h provided on the rear side of the elevator 61 extends forward. The front end portions 59e and 59f on the front side and the rear side overlap each other in the middle between the front and rear sides with a space in the vertical direction. The upper and lower tip portions 59e and 59f are inserted from the front and rear into the connection grooves 53c and 54c of the selected set-up plates 53 and 54, respectively. The overlapping front end portion 59e is provided with a long hole 59i, and the front end portion 59f is provided with a pin 59j. The pin 59j is inserted into the long hole 59i and engaged therewith. When the pin 59j is driven by the cam 56a moved by the selection mechanism 58, the lock members 59a and 59b swing, and the upper and lower portions of the overlapping portion of the upper tip portions 59e and 59f and the overlapping portion of the lower tip portions 59e and 59f open and close. To do. When the upper and lower portions of the overlapping portions of the tip portions 59e and 59f are opened, the upper and lower portions of the connection grooves 53c and 54c are pressed from the inside to be connected and locked. When the upper and lower portions of the overlapping portions of the tip portions 59e and 59f are closed, the state of connection and lock is released by stopping the pressing. The locked state is maintained by urging by the springs 59c and 59d hung between the upper and lower ends of the lock members 59a and 59b.

  FIG. 10 shows the operation of the set-up device 51 of FIG. 8 as viewed from the left side. (A) is a state in which a set-up plate is selected and connected and locked to the elevator 61, (b) is a state in which selection of the set-up plate 54 is stopped and the connection and lock are released, and (c) is a knitting state. FIG. 6D shows a state approaching the selection of the feed plate 53, and FIG. 6D shows a state where the set-up plate 53 is selected and connected and locked to the elevator 61. The selection mechanism 58 and the cam 56a are displayed only in (a), and only the action portions 56b and 56c of the cam 56a are indicated by thick solid lines in (b), (c), and (d).

  In the state shown in (a), the action portions 56b and 56c of the cam 56a do not act on the pin 59j provided on the lock member 59b. The upper and lower portions of the portion are opened, and the connecting groove 53c is pressed in the vertical direction in the figure from the inside. Since the overlapping portions of the tip portions 59e and 59f are disengaged from the connection groove 54c of the set-up plate 54, if the elevator 61 is raised, only the set-up plate 53 can be raised in a connected and locked state. it can. Similarly, in the state shown in (d), only the set-up plate 54 can be raised in a connected and locked state. Since the upper action portion 54c has a narrow front-rear width, in the state shown in (a) and (d), the pin 59j moves away from the ascending path, and the lift 59 raises the pin 59j. it can.

  In the second embodiment, the two set-up plates 53 and 54 are switched. However, if the set-up plate has similar connecting grooves 53c and 54c on the substrate, three or more cams 56a can be adapted. The set-up plate can be switched to be connected and locked to the lift 61. Further, each set-up plate 3, 4, 5; 23, 24; 53, 54 is arranged in parallel with the set-up needle 2 on the substrates 3a, 4a, 5a; 23a, 24a; 53a, 54a supported on both sides of the knitting width. The operating plate portions 3b, 4b, 5b; 23b, 24; 53b, 54b are supported. However, the substrates 3a, 4a, 5a; 23a, 24a; 53a, 54a and the operation plate portions 3b, 4b, 5b; 23b, 24; 53b, 54b can be integrated. When integrating, it can also be made into the shape of one rectangular plate.

  Since the connection mechanisms 29 and 59 of the first and second embodiments do not need to move the elevators 31 and 61 in the knitting width direction, the connection mechanism can be simplified. However, even in the set-up device 1 of FIG. 1, if the elevator 31 is moved in the knitting width direction in a direction away from the set-up plate substrate, the holder for accommodating the set-up plate is moved in the front-rear direction by the selection mechanism. Can be made. Even if there are three or more set-up plates, if the set-up plate is selected, the elevator can be returned to the set-up plate side and the selected set-up plate can be moved up and down.
