Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for arranging a plurality of thin plates having the same size in a straight line and at regular intervals on a plane at the end of a conveyor. The present invention relates to a device for aligning thin plates before an automatic mounting device for putting a flexible plate such as a substrate or a film or photographic paper in the photographic industry in a hanger frame for carrying and working.

[0002]

2. Description of the Related Art It may be advantageous to place a plurality of thin plates having the same shape in a frame in the process of handling them. When handling a thin plate having no particular rigidity, for example, in order to plate the printed circuit board as described above, it is lifted or immersed in a liquid, so that it is necessary to put the flexible plate of the propeller into the frame. The present invention relates to a device for mounting a thin plate on a frame by arranging the thin plate on a plane at regular intervals and arranging the sides in a straight line. In order to automatically install a plurality of flexible plates of the same size in the frame, one frame of flexible plates must be neatly arranged in front of the mounting device at the end of the conveyor. No automatic device of such an arrangement has ever existed. The same inventor has filed an application for the above-mentioned mounting device on April 9, 1992 as "mounting device for mounting flexible plate on hanger frame for transportation". In the above description, the arrangement of the plates is referred to as a pre-process or another invention, which indicates the apparatus of the present invention. The flexible plates are conveyed horizontally on a conveyor and arrive in line on a short reversing conveyor in front of the mounting device.

[0003]

The thin plate of the same shape which is fed horizontally on the conveyor can be accurately moved in a fixed direction regardless of its rigidity, the gap between the front and rear plates can be set at a fixed interval, and the traveling direction can be improved. It is an object of the present invention to provide a device for arranging so that the sides of are aligned.

[0004]

In the present invention, the sheets are to be carried by a main conveyor and aligned on a short alignment roller conveyor. First, a transfer roller conveyor is provided between the main conveyor and the alignment roller conveyor. Aligning conveyors and transfer conveyors are a type of conveyor in which each roller is arranged in several rows and a belt is hung on the rollers, and narrow belt conveyors are arranged in parallel. However, the leading roller of the alignment conveyor has a single shaft and is rotated by a servomotor. Therefore, both narrow belts move at the same speed. In the transfer conveyor, the last roller is rotated by a single motor and usually rotated by a motor. In addition, the transfer conveyor is an alignment conveyor and the maximum length of the thin plate to be handled is 1
Overlaid by more than one sheet.

The transfer conveyor is supported by a lifting cylinder so as to move vertically above and below the alignment conveyor, and is connected to the main conveyor when the transfer conveyor is above. In such a configuration,
At the tip of the transfer conveyor, a stopper that locks in a plate shape or at two points so that one side of the thin plate stops at right angles to the traveling direction, and a cylinder that raises and lowers the transfer conveyor below or above the alignment conveyor are aligned. Servo motor that moves the thin plate transferred to the conveyor by a distance that is equal to the length and specified interval, a controller that continuously operates the lifting cylinder and the servo motor a specified number of times, and a straight line parallel to the center line on the side of the alignment conveyor. It is composed of a large number of adjusting rods each having an adjusting surface, and a traversing cylinder which moves the plurality of adjusting rods at once at right angles to the center line.

[0006]

[Operation] When the thin plate is transferred from the main conveyor to the transfer conveyor at the same height as the upper position, the transfer conveyor is started and the thin plate hits the stopper plate installed at the tip of the transfer conveyor. , The transfer conveyor is stopped. By abutting one side of the thin plate on the stopper, the side in the traveling direction of the thin plate is corrected exactly parallel to the center line of the conveyor. The transfer conveyor then takes advantage of the roller position discrepancy to pass through the alignment conveyor by the lowering of the vertical cylinders and exit below it. At that time, the thin plate is left on the alignment conveyor with the corrected position and posture. When the vertical cylinder finishes descending, the servo motor of the alignment conveyor rotates by the distance of the length of one sheet plus the specified clearance calculated in advance, and the sheet keeps the angle of the traveling direction parallel to the center line of the conveyor. Proceed the above distance on the alignment conveyor and stop. When the above operation is repeated a specified number of times calculated, the thin plates are arranged on the alignment conveyor with the specified number of sheets at a constant interval and one side parallel to the center line of the conveyor. However, the edges in the direction of travel of the thin plates are not aligned with each other due to the ingress and egress of each thin plate. In order to correct it, vertical adjusting rods are arranged parallel to the center line on the side of the alignment conveyor, and if these are pulled toward the center line side by the traverse cylinder under the alignment conveyor, The adjustment surface pushes the thin plates all together toward the center line. At this point the lamellas are fully aligned.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of each conveyor. The main conveyor 1 may have a structure that smoothly transfers the thin plates when the transfer conveyor 2 is at the highest position by the vertical cylinder 4. The transfer conveyor 2 is a type of conveyor in which narrow child belt conveyors are arranged in parallel, the rearmost rollers of the conveyors are fixed to one axis, and are usually rotated by a motor. Overlapping the maximum length. The aligning conveyor 3 is also a parallel arrangement of the child belt conveyors, and the overlapping portion does not use the lateral frame together with the transfer conveyor 2, and the lateral positions of the child belt conveyors of both conveyors are displaced as shown in FIG. Therefore, the transfer conveyor 2 can be moved up and down through the gap of the alignment conveyor 3 by the lifting cylinder 4. Reference numeral 5 is a lifting rail guide.

A plate or two or more vertical bars is provided as a stopper 6 at the leading end of the transfer conveyor 2, and the thin plate transferred from the main conveyor 1 goes to the leading end of the transfer conveyor 2 and hits the stopper 6. When the belt comes into contact with the belt and stops, the transfer conveyor 2 stops after the direction of one side of the belt is fixed at a right angle to the center line of the conveyor. At the same time, the elevator cylinder 4 starts to descend, and the alignment conveyor 3
Place a thin plate in between and descend further to align conveyor 3
Go out to the bottom and stop. The servo motor 7 of the alignment conveyor 3 which has received the thin plate advances and stops the belt by the distance in the moving direction of the thin plate plus the distance to the next plate as programmed in advance. Repeat the above operation. As a result, a specified number of thin plates are arranged on the alignment conveyor 3 with the side direction and the interval accurately.

Next, as shown in FIG. 2, the alignment conveyor 3 is provided with a row of adjusting rods 9 having adjusting surfaces 8 arranged parallel to the center line on the side surface of the conveyor, and a traverse cylinder 10 installed below the conveyor. , Horizontal movement of the sheet at a time at a right angle to the center line and pushing the thin plate to a certain line on the center line side adjusts the entrance and exit of the side parallel to the center line of the thin plate in a straight line. By the above operation, the thin plates are accurately aligned.

[0010]

According to the present invention, when a plurality of thin plates are put in a frame so that they can be handled in various ways, a device for mounting the thin plate on the frame (Patent application “Flexible plate by the same inventor of April 9, 1992”) It can be used effectively when connecting thin plates at equal intervals, for example, for unmanned processing on a conveyor without putting it in the frame). I will contribute.
