When the front / rear / left / right alignment is completed, the up / down cylinder 17 is raised. Based on a signal (sequence program) that the lift table 43 arranged downstream of the conveyor 14 is in a state where it can accept the display plate 11, the front frame stopper 16 delivers the display plate 11 when it is placed in the raised position. Is called.
Note that during alignment, the transport of the display plate 11 is prevented by a rear frame stopper (not shown).

The procedure for aligning the display plate is as shown in FIG. First, when a not-shown display plate detecting means (for example, a proximity sensor) detects that the display plate 11 does not exist below the display plate aligning device 10 (STEP 1), the rear frame stopper is disposed at the raised position (STEP 2). The display plate 11 that has been stopped by the rear frame stopper on the transport surface of the continuously operating conveyor 14 is transported under the support plate 15 by the conveyor 14 and comes into contact with the front frame stopper 16 and stops. Note that the rear frame stopper is disposed at the lowered position after a predetermined time has elapsed, and stops the display plate 11 that is transported next. Subsequently, when a display plate detecting means (not shown) (for example, a phototube type) detects the display plate 11 (STEP 3), the vertical cylinder 17 is lowered, and the front / rear alignment bar 23 and the left / right alignment bar 33 are in contact with the display plate 11. (STEP4). For the front-rear alignment, the front-rear alignment bar 23 presses the raised portion of the inner frame 13 or the rear edge of the inner frame 13 and presses the outer frame 12 against the front frame stopper 16, so that the front edge of the outer frame 12 is This is performed by being parallel to the front frame stopper 16 and bringing the front edge of the inner frame 13 into contact with the front edge of the outer frame 12 (STEP 5). For left-right alignment, the left-right alignment bar 33 presses the raised portion of the inner frame 13 or one of the left and right side edges of the inner frame 13 to contact one side edge of the outer frame 12 with the side edge of the inner frame 13 on the same side (STEP 6).
When the alignment is completed, the upper and lower cylinders are raised (STEP 7), and the front frame stopper is placed at the raised position based on the signal that the lift table 43 is ready to accept the exhibition plate 11 (STEP 8). Is done. When conveyance of the display plate 11 is completed, the front frame stopper is again placed at the lowered position (STEP 9), and the same operation is repeated.
The front / rear position aligning means 20 and the left / right position aligning means 30 may be driven simultaneously.

  Next, the baking apparatus 40 will be described. The baking apparatus 40 is disposed on the downstream side of the conveyor 14 of the display plate aligning apparatus 10 (downstream of the front frame stopper), and ascends and descends by a screw screw 42 driven by a lift up / down motor 41 as shown in FIG. The table 43 and a baking board 44 provided at the raised position of the lift table 43 are configured.

  The lift table 43 under the baking sheet 44 is provided with a stopper 51 at the edge of the conveyor 14 in the traveling direction. When the lift table 43 is on standby, the lift table 43 and the conveyor 14 are on the same plane, and the display plate 11 conveyed on the conveyor 14 is stopped on the lift table 43 by the stopper 51. When the display plate 11 reaches the position of the stopper 51, a display plate detection means (for example, a photoelectric tube type) (not shown) provided in the baking apparatus 40 detects the display plate 11 and operates the lift table 43. When the lift table 43 is in operation (that is, when the lift table 43 is not in a state where it can receive the display plate 11), the front frame stopper 16 prevents the display plate 11 from being carried into the lift table 43. .

  FIG. 8 shows a state where the lifting plate 11 conveyed by the conveyor 14 is placed on the lift table 43 and then lifted by driving the lift up / down motor 41 and rotating the screw screw 42. When the lift table 43 comes to the ascending end, the ascending end proximity switch 48 is pushed, the ascent of the lift table 43 is stopped, and the upper surface of the product placed on the display plate 11 is baked by the baking pan 44. After a certain time, the lift up / down motor 41 rotates reversely, and the lift table 43 descends. When the lift table 43 is lowered to the same plane as the conveyor 14, the display plate 11 is placed on the conveyor 14 and stopped by the stopper 51. When the lift table 43 further descends to the descending end (the position where the top of the stopper 51 of the lift table 43 is below the conveying surface of the conveyor 14), the stop by the stopper 51 is released and the display plate 11 is discharged from the conveyor 14. . After discharging, the same operation is repeated again.
