JPH0612868Y2 - Plate material posture adjustment device on the conveyor - Google Patents

Description

[Detailed Description of the Invention] [Industrial field of application] This invention relates to a plate material posture adjusting device on a conveyor, and more specifically, it automatically aligns plate members on a coating line for flat roofing materials to keep the posture constant. It relates to a device used for adjusting.

[Conventional technology]

In an automatic coating line for flat roof materials, belt conveyors A and B are arranged in a zigzag shape as shown in FIG.
The applicant of the present application has previously proposed a device for performing a two-tone color coating by _{disposing the} coating device D at the turning point C (for example, Japanese Patent Laid- _Open No. _61-4567 or Japanese _{Utility Model} Laid- _Open No. _62-66775 ).

In the above-mentioned coating apparatus, it is premised that the plate material is supplied in a fixed posture, and as a posture adjusting apparatus thereof, a bending correction device F is provided in the supply portion E'of the plate material supply conveyor E as shown in FIG. The position of the plate material is adjusted by hitting the claws G of the device F.

[Problems of conventional technology]

However, with the above attitude adjusting device F alone, the plate material P
Due to the non-uniformity of the contact state between the nail and the claws G, G may be bent and jam at the turning point C.
Even if they are aligned correctly, the plate material may be displaced in a meandering shape due to vibration during transportation on the conveyor, and the plate material may be sent to the coating section H in a bent posture, resulting in defective products. There was.

Therefore, there is a drawback in that the monitoring cannot be neglected in order to correct such a defect and labor saving cannot be achieved.

[Problems to be solved by the device]

In view of the above problems, the present invention provides a plate material posture adjusting device on a conveyor that can reliably adjust the posture of the plate material in the transport path when supplying the plate material to the coating section and prevent meandering. It was done for the purpose.

[Technology for solving problems]

That is, according to the plate material posture adjusting device on the conveyor of the present invention, a rotating disk is axially supported on the side of the conveyor for transferring the plate-like member with the rotating surface parallel to the conveying surface of the conveyor, and the peripheral edge is on the rotating disk. A plurality of idle rollers are erected vertically at equal intervals in the rear part, and are arranged so that the rotation zone drawn by the outer circumference of the idle roller is brought into contact with the outer edge of conveyance of the plate-like body as the rotary disk rotates. In addition, at the transfer start end of the folding conveyor arranged in a zigzag shape with respect to the end of the conveyor, a correction roller having two conical rollers on the same shaft and having their conical surface portions opposed to each other and pivotally supported at both ends. Is rotatably supported in a direction perpendicular to the conveying direction of the conveyor, and a turning device for receiving the conveying plate material at the turning point between the conveyor and the turning conveyor and then pushing the sheet toward the turning conveyor. Than it is.

〔Example〕

 Next, this invention will be described with reference to examples.

FIG. 1 is an overall side view of an embodiment of the present invention, and FIGS. 2 and 3 are perspective views of the essential parts of the embodiment. For example, a side view of a conveyor 1 for carrying a plate material P such as a roof material. As shown in FIG. 2, the rotating surface 2A is parallel to the conveying surface of the conveyor 1, and the rotating disk 2 is pivotally supported by the arm 3. The idler rollers 4 ... Vertically arranged at equal intervals, the rotation zone 4A drawn by the rotation of the rotating discs of the idle rollers 4 ... At the end, as shown in FIG. 1, a rolling device 10 which receives a plate-like body P and swings downward as shown by an arrow Y and pushes it out is used as a drive source. 1 and the folding conveyor 1'which is arranged in a zigzag shape, has the same axis 5 at the start end thereof. Number of conical rollers 6A, 6A a conical surface 6B, modified roller 6 that is rotatably supported at both ends by a are opposed to each other 6B is pivotally supported now configured at a right angle with respect to the transport direction of the conveyor 1 (arrow X).

In the above description, reference numeral 3A in the drawing denotes a link for adjusting the inclination angle θ of the arm, which is provided to adjust the immersion of the rotation zone 4A of the idler rollers 4 ... 4 according to the outer edge P'of the conveyance of the plate P. There is.

[Action]

In the device for adjusting a posture of a plate material on a conveyor according to the present invention, the plate material P is conveyed by the conveyor 1. At this time, the plate material P
Is not correctly oriented in the transfer direction (arrow X), the side edge of the plate material P is corrected by contact with the rotating idler rollers 4 ...

Next, the plate material P is the catch member 1 of the cylinder device 10A.
When the plate P is meandering with respect to the traveling direction (arrow X) at this time, it is received by 0B and oscillated downward and then rolled in the direction of the folding conveyor 1'and pushed out. The correction roller 6 provided is brought into contact with the slant surfaces of the conical rollers 6A, 6A facing each other, so that the correction roller 6 is translated in a direction perpendicular to the transfer direction (arrow X), and the position is corrected to the center of the conveyor 1 '.

Therefore, the plate material P is correctly aligned in the transfer direction.

〔effect〕

As described above, according to the present invention, the plate material P is automatically corrected in its orientation and alignment state, and can be supplied to the coating apparatus without any monitoring.
