The stroke of each first pressure cylinder 17 is set such that the distance between the opposing first pressure rolls 21 moved toward each other is slightly smaller than the distance between the inclined side walls 6c of the top plate 6. You. Above the middle portion of the frame 3, second pressing cylinders 23, which constitute a part of a second pressing member having an axis in the vertical direction, are respectively mounted. A second pressing roll 25 having an axis in the horizontal direction and forming a part of a second pressing member that rotates in the longitudinal direction of the frame 3 is provided near the inclined side wall 6c of the loaded top plate 6. Each is rotatably supported relative to the upper surface of the bottom surface 6b. Below the middle part of the frame 3 are mounted third pressure cylinders 27 each constituting a part of a third pressure member having an axis in the vertical direction. The third pressure roll 29, which has a horizontal axis and forms a part of a third pressure member that rotates in the longitudinal direction of the frame 3, includes a bottom plate 6 b and an inclined side wall of the loaded top plate 6. 6c are rotatably supported relative to the lower surface of the bent portion. The first to third pressure rolls 21, 25, 29 are made of a hard urethane rubber material having some elasticity. The opposing first pressure roll 21 is composed of two rolls spaced at a predetermined distance in the transport direction as described above, and the first pressure roll 21 located on the lower side in the transport direction is included in the two rolls. A large-diameter flange portion 21a is integrally formed on the upper portion, and the large-diameter flange portion 21a comes into contact with the upper end of the inclined side wall 6c of the top plate 6 that is moved at the time of correction to restrict the floating. Next, the deformation correcting operation of the top plate 6 will be described. 5 to 7 are explanatory diagrams showing the correction operation. First, the transfer cylinder 7 is operated so that the rod is extended, and the carriage 11 is moved to the loading side of the frame 3 to be on standby. At this time, the extruding plate 15 of the carriage 11 is moved to a lower position that does not intersect with the conveying surface of the conveyor 5 and waits for the carry-in of the top plate 6. Then, the top plate 6 from which the baked bread has been taken out is carried into the bread baking plate correcting apparatus 1 by the carrying-in conveyor and the carrying drive of the conveyor 5, and its front end in the carrying direction is the first to third processing units. When the rear end in the conveying direction is moved to a position passing through the extruding plate 15 while being positioned on the pressure rolls 21, 25, 29, the conveying of the top plate 6 by the conveyor 5 is interrupted and stopped. (Refer to FIG. 5) Next, in the above state, the first pressure cylinders 17 are respectively operated to move the opposing first pressure rolls 21 in a direction in which the first pressure rolls 21 approach each other, and the inclined side wall of the top plate 6 is moved. After being pressed against the upper portion of the bottom plate 6b near the side wall 6c, the third pressing cylinder 27 is moved to the third position. The pressure roll 29 is pressed against the bottom surface of the bent portion of the bottom plate 6b and the inclined side wall 6c. (See FIG. 6) Next, in the above state, the extruding plate 15 is moved upward by operating the lifting / lowering cylinder 13 and positioned at the rear end side of the top plate 6 in the transport direction, and then the transfer cylinder 7 is operated and moved.

At this time, the correction of the top plate 6 by the deformation correcting device 1 is not performed every time, but is set to be performed every appropriate number of times, for example, three times. When no correction is performed, the conveyor 5 is continuously transported and driven. What is necessary is just to pass through the top plate 6. In the present embodiment, the upper part of the inclined side wall 6c is moved in a direction in which the upper part of the inclined side wall 6c is brought close to each other with the inclined side wall 6c and the base end of the inclined side wall 6c near the inclined side wall 6c as the top plate 6 moves. By returning the inclined state of the inclined side wall 6c to the initial state by applying pressure, the deformation of the bottom plate 6b that has been curved and deformed in a protruding manner can be corrected to a planar shape. Embodiment 2 FIG. 8 is a left side view of the deformation correcting device. The deformation correcting device 51 according to the present embodiment has a structure in which an intermediate portion pressing body 53 is provided in the deformation correcting device 1 of the first embodiment. That is, a fourth pressure cylinder 55 is mounted above a middle portion in the longitudinal direction of the frame 3 between the pair of second pressure cylinders 23, and a rod of the fourth pressure cylinder 55 is made of, for example, hard urethane rubber. As described above, a structure in which the pressing member 57 having some elasticity is attached is provided. The pressing member 57 may be a roll or a block. Further, the same members as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

And the fourth pressing cylinder 55 is operated to press the pressing member 57 against the upper surface of the bottom plate 6b to deform it into a concave shape. Then, while the bottom plate 6b is bent downward by the pressing member 57 that slides on the upper surface with the movement of the top plate 6, the inclined side wall 6c is returned to the initial inclined state while the bottom plate 6b that has been bent and deformed in a protruding manner is made flat. Fix it. In the description of the first and second embodiments, the second pressure cylinder 23, the third pressure cylinder 27, and the fourth pressure cylinder 55 are fixedly attached to the frame 3. Since the width of the second pressure cylinder 23 and the third pressure cylinder 27 needs to be adjusted depending on the type of the top plate 6, the structure may be such that the positions can be adjusted in the direction orthogonal to the longitudinal direction of the frame 3. That is, as shown in FIG. 10 showing the mounting state of the second pressure cylinder in a plane (however, FIG. 10 shows only the second pressure cylinder, but the same applies to the third pressure cylinder). A shaft 61 having a different diameter cross-sectional shape having an axis in a direction orthogonal to the longitudinal direction is attached to the mounting position of the second pressure cylinder 23 and the third pressure cylinder 27 on the frame 3. The cylinder bases of the pressure cylinder 23 and the third pressure cylinder 27 are supported so as not to rotate and to be movable in the axial direction. Further, a pair of adjusting screws 63 facing the frame 3 corresponding to the side surfaces of the cylinder bases of the second pressure cylinder 23 and the third pressure cylinder 27 are screwed respectively so as to be able to advance. The position of the third pressure cylinder 27 may be adjusted by changing the contact state of each adjusting screw 63 with respect to both surfaces of the cylinder base end.

Then, the second pressure cylinder 23 is operated to move the second pressure roll 25 to the upper surface of the bottom plate 6b near the inclined side wall 6c, and the third pressure cylinder 27 is moved to operate the third pressure cylinder. The roll 29 is pressed against the lower surface of the bent portion of the bottom plate 6b and the inclined side wall 6c. (See Fig. 6)

Next, in the above state, the extruding plate 15 is moved upward by operating the lifting / lowering cylinder 13 to be positioned at the rear end side in the transport direction of the top plate 6, and then the extruder is moved by operating the transfer cylinder 7.

When the top plate 6 is moved by the moving extruding plate 15, the top plate 6 whose deformation has been corrected by the pressure contact of the second and third pressure rolls 25 and 29 is easily lifted. Of the one pressure roll 21, the upper end of the inclined side wall 6c abuts against the large-diameter flange 21a of the first pressure roll 21 disposed on the lower side in the transport direction, thereby restricting the rise of the top plate 6 and correcting the deformation.
