Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a thin plate transport apparatus for transporting a thin plate such as a cardboard for making a paper case and a plastic card such as a cash card or a prepaid card to a predetermined location.
[0002]
[Prior art]
An example of the thin plate conveying apparatus is disclosed in Japanese Patent Laid-Open No. 6-72575. This is because suction means composed of a suction pipe having a suction port opened on the lower surface for sucking upward the thin plate body positioned at the top of the thin plate bodies stacked in the vertical direction on the storage portion is disposed above the storage portion. And a pair of pull-out rollers as a conveying means for contacting the upper surface of the thin plate body sucked by the suction force of the suction means and feeding the thin plate body in the horizontal direction. The upper thin plate member is sucked upward by the suction force of the suction means, and then separated from the second thin plate member located immediately below the sucked thin plate member, and then transported. I am trying to hand it over to the means.
[0003]
As described above, the thin plate body positioned at the uppermost portion is separated from the second thin plate body immediately below by the suction force of the suction means, and then transported to transport the thin plate body positioned at the uppermost portion in the horizontal direction. In this case, since the lower surface of the second thin plate member does not rub against the upper surface of the second thin plate member, the thin plate member can be transported without damaging the upper surface of the second thin plate member. In the state in which the suction force is acting, it is configured to forcibly move in the horizontal direction by the rotational force of the pulling roller, so that slip occurs between the outer peripheral surface of the pulling roller and the upper surface of the thin plate member, There is a disadvantage that the posture is largely changed from the time when the thin plate is received. As described above, if the posture of the thin plate is largely changed, it cannot be aligned when transported to a predetermined location, and post-processing cannot be performed quickly. For example, after transporting a thin plate with a printed surface to a predetermined location, when checking the surface scratches with a TV camera or the like to determine whether the thin plate is good or not, It is necessary to correct the posture again so that it can be image-processed, and it takes a lot of time to judge the quality of the thin plate, and it is impossible to process many thin plates in a short time.
[0004]
In order to solve the above inconvenience, for example, it is conceivable to provide a guide for forcibly correcting the thin plate body to a predetermined posture by contacting the thin plate body whose posture has been changed. Therefore, the contacted portion, particularly the corner portion of the thin plate member, may be bent and scratched, which is difficult to implement. While providing a cushioning material so as not to damage the thin plate body, it may be possible to provide a guide over a long distance so that the posture of the thin plate body is gradually changed, but the cost increases and the whole apparatus becomes large, Moreover, since it is necessary to change the position of the guide with respect to the thin plate every time a thin plate having different dimensions is conveyed, it is difficult to put it to practical use.
[0005]
[Problems to be solved by the invention]
In view of the above-described situation, the present invention intends to provide a thin plate conveying apparatus that can convey a thin plate without damaging the thin plate and without changing the posture.
[0006]
[Means for Solving the Problems]
  In order to solve the above-described problems, the present invention provides a storage unit that stores a state in which the surface is oriented substantially in the horizontal direction, and a thin plate member stored in the storage unit is moved upward by adsorbing from the upper surface thereof. 1 transport device and a second transport device that receives the thin plate member moved by the first transport device from above and moves it to a predetermined position in the horizontal direction while being attracted, and is moved by the first transport device. Before the thin plate body received by the second transport device is configured to stop the thin plate body suction operation by the first transport device,A vacuum pad for adsorbing the thin plate member stored in the storage unit from the upper surface thereof, a vacuum rod for supporting the vacuum pad so as to be movable up and down, and a vacuum rod through the vacuum pad. It is composed of an air suction device for sending suction air and a drive device for moving the vacuum rod up and down, and the vacuum rod is not supplied with a state in which suction air from the air suction device is supplied to the vacuum pad by its vertical movement. It is configured as a switching valve for switching to a state, and the suction air supply passage formed in the vacuum pad is configured to communicate with the outside air by moving the vacuum rod upward.Thus, a thin plate conveying apparatus was configured. Accordingly, when the thin plates stored in the storage unit are transported one by one to a predetermined location, the upper surface of the thin plate positioned at the top is adsorbed by the first transport device, and then the thin plate is moved upward. After that, the thin plate member is received by the second transport device and moved to a predetermined position in the horizontal direction. And, since the thin plate body moved by the first transport device is stopped by the second transport device before the thin plate body suction operation by the first transport device is stopped, the suction force by the first transport device is reduced. Since it does not act on the thin plate member, slip does not occur between the second transport device and the upper surface of the thin plate member, and it can be smoothly transported with the posture received by the second transport device. Even if the suction operation of the thin plate body by the first transport device is stopped, it remains in a negative pressure state for a certain period of time, so that it does not fall before the thin plate body is transferred from the first transport device to the second transport device. .A vacuum pad for adsorbing the thin plate member stored in the storage unit from the upper surface thereof; a vacuum rod for supporting the vacuum pad so as to move up and down; and a vacuum pad on the vacuum pad. An air suction device for sending suction air through the rod, and a drive device for moving the vacuum rod up and down, and supplying the suction air from the air suction device to the vacuum pad by moving the vacuum rod up and down; Since the suction air supply passage formed in the vacuum pad is configured to communicate with the outside air by moving the vacuum rod upward, the vacuum rod is moved downward. By moving it, the suction air from the air suction device is supplied to the vacuum pad. Can be switched to the state of, it is to adsorb the thin plate member in the vacuum pad. By moving the vacuum rod upward in this adsorbed state, the suction air from the air suction device can be switched to a state where it is not supplied to the vacuum pad, and the suction air supply passage can be communicated with the outside air. The suction force of the vacuum pad is released. In this case, since the vacuum rod is in a negative pressure state for a certain time, the thin plate body does not fall immediately from the vacuum pad after releasing the suction force of the vacuum pad.
[0008]
The transport width of the second transport device is configured to be smaller than the left and right width of the thin plate member, and the thin plate member transported by the second transport device is received below the transport direction lower side of the second transport device to receive the lower transport direction. A third transport device that moves to the side, and the entire lower surface of the thin plate that has been transported while being adsorbed by the second transport device is attracted to the transport surface of the third transport device to make the thin plate flat In this state, the sheet is conveyed to the lower side in the conveying direction in this state. By the way, the thin plate member conveyed by the second conveying device is in a state where only a specific portion is adsorbed, and is conveyed in a state where the thin plate member is bent like a bow. In this way, the entire lower surface of the thin plate conveyed in a bowed state is adsorbed to the conveying surface of the third conveying device, and the thin plate returns to the original flat shape and is conveyed in the lower direction in the conveying direction. It is done.
[0009]
There is provided an urging means for urging and moving the vacuum rod downward, and the drive device is brought into contact with a rotating cam and an outer peripheral surface of the rotating cam in order to convert the rotating motion of the rotating cam into a swinging motion. The swing arm, an electric motor for rotating the rotating cam, and connecting the swing arm and the vacuum rod to change the swing motion of the swing arm to the vertical movement of the vacuum rod, Since the connecting portion between the swing arm and the vacuum rod is provided with a vertical interchange portion, even if the vibration generated in the rotating cam driven and rotated by the electric motor is transmitted to the swing arm, this vibration is reduced. The accommodation part provided in the connection part of a rocking | swiveling arm and a vacuum rod can absorb.

Therefore, the left and right rotary cams 23 and 23 (only one is shown in the figure) attached to the spline shaft 21 in an integrally rotated state by the drive of the servo motor 22 are integrally driven and rotated. The rotating rollers 27, 27 in contact with the outer peripheral surface move up and down by following the outer peripheral surface of the rotating cams 23, 23. As the rotary roller 27 moves up and down, the swing arm 24 swings and moves the vacuum rod 13 in the vertical direction. FIG. 3 shows a state in which the vacuum rod 13 is moved to the highest position. In this state, the outside air intake port 16A communicates with the outside air, and the suction air intake port 16B extends from the circumferential groove 17B for supplying suction air. When the vacuum rod 13 is moved to the lowermost position shown in FIG. 4 (b) from this state, the suction to the thin plate member 1 by the vacuum pad 12 is released by moving to a position deviated upward. 16A is sealed by the inner surface of the bush 18, and the suction air intake port 16B is positioned in the peripheral groove 17B for supplying suction air, and the suction of the thin plate 1 by the vacuum pad 12 is started.

【The invention's effect】
  According to the first aspect of the present invention, the thin plate member moved by the first transfer device is configured to stop the adsorption operation of the thin plate member by the first transfer device before being received by the second transfer device. Since no slip occurs between the apparatus and the thin plate body, the thin plate body moved by the first transport device can be delivered and transported to the second transport device in the moved posture. This eliminates the need for a posture change guide or the like for changing the posture to a predetermined posture, and enables good conveyance without damaging the thin plate during conveyance.Further, when the vacuum rod is moved up and down to mechanically switch between the state where the suction air is supplied to the vacuum pad and the state where the vacuum air is not supplied, for example, when the solenoid valve is switched, the control of the solenoid valve is controlled. This requires not only various sensors and control devices, but also a complicated structure and high cost. In particular, it is very difficult to set the switching timing for a vacuum rod that moves up and down at high speed. The switching timing changes greatly with the use ofThe problems that have been changed and require readjustment can be solved at once.
