Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a panel loading device, and more particularly to a technique for simplifying the movement of a gripping device for gripping panels.

[Background technology]

Conventionally, panels transported by a conveyor are grabbed by a chuck device, the grip device is raised, the grip device is then transferred to a loading position, a lifter is raised and lowered at the loading position, and the panel is received.
Panels were stacked in multiple stages on a lifter. However, with such a configuration, the structure of the gripping device becomes complicated, resulting in frequent troubles. To solve this problem, as in Japanese Utility Model Publication No. 51-52145, the cart is moved horizontally, receives a workpiece such as a pallet from the lifter on one side, and then lifts it onto the platform on the other side. It has also been proposed that the workpiece be loaded on the platform, but in such a configuration, when receiving the workpiece and when loading the workpiece separately, there is a need to move between the cart, which can move only in the horizontal direction, and the lifting lifter and the lifting platform. There is a problem in that it is difficult to match the timing of receiving the workpiece, and therefore it is difficult to configure the gripping claw for gripping the workpiece, and it is difficult to adopt the configuration of the gripping claw.

[Purpose of the invention]

The present invention has been made in view of these problems, and its purpose is to provide a panel loading device that can simplify the configuration of the gripping device and also adopt the configuration of the gripping claws. It's about doing.

[Disclosure of the invention]

The present invention provides a conveyance terminal conveyor 3 at the terminal end of the panel conveyor 2 that conveys the panel 1 to a fixed position.
A lifter 4 is provided adjacent to the conveyance end conveyor 3 so as to be movable up and down, and a panel 1 at a fixed position on the conveyance end conveyor 3 can be gripped. A gripping device 5 is provided in which gripping claws 9, 9 can be freely moved toward and away from each other, and a claw portion 13 that is pressed against the panel 1 against the base 12 of the gripping claw 9 is slidable in the vertical direction to convey the gripping device 5. Terminal conveyor 3
The present invention relates to a panel loading device characterized in that it is provided with a horizontal moving means 6 that reciprocates in a substantially horizontal direction between an upper position and an upper position of the vertical lifter 4. Therefore, we were able to achieve the above objective.

An embodiment of the present invention will be described in detail below with reference to the drawings.

A conveyance end conveyor 3 is provided at the end of the panel conveyor 2 that can convey the panels 1 to a fixed position. This conveyor end conveyor 3 is configured to be driven up and down by a hydraulic cylinder 7. An elevating lifter 4 is provided adjacent to the conveyor end conveyor 3 so as to be movable up and down. A gripping device 5 is provided which can grip the panel 1 at a fixed position on the end conveyor 3. The gripping device 5 is made to be able to reciprocate approximately horizontally between a position above the conveyor end conveyor 3 and a position above the elevating lifter 4. The gripping device 5 is provided with horizontal movement means 6 for horizontally moving it. Such horizontal movement means 6
uses a hydraulic cylinder 8, but other types may be used. Furthermore, the gripping device 5 has gripping claws 9, 9 on both sides of the conveyor end conveyor 3, respectively, and these gripping claws 9, 9 are movable in a reciprocating direction in the gripping direction of the panel 1.

According to such a configuration, the panel 1 is conveyed to the stopper 10 provided on the conveyor end conveyor 3, and the waiting device 5 clamps the panel 1. Here, panel 1 is centered. After clamping, the conveyor end conveyor 3 is lowered by the hydraulic cylinder 7, and then the gripping device 5
moves horizontally onto the elevating lifter 4. After the movement, the elevating lifter 4 rises, releases the grip, and loads.

As shown in FIG. 2, the gripping claw 9 is provided with a proximity switch 11.
The upper end of the panel 1 that has already been loaded is detected, and based on this detection result, the grip claw 9 is released from the grip after about 0.5 seconds, and the lifting lifter 4 is stopped from rising.
The next panel 1 can be loaded correctly on top of the panel 1 on the ascending lifter 4.

As shown in FIGS. 3 and 4, the gripping pawl 9 has a pawl portion 13 that is groove-fitted into the base 12 of the gripping pawl 9. By detecting the top edge,
Even if the panel 1 on the gripping device 5 side is pushed up by the panel 1 on the lifting lifter 4 side when the lifting lifter 4 is stopped after a certain period of time and the grasping device 5 is released, the claw portion 13 escapes in the dovetail groove. , the panels 1 can be loaded correctly without any difficulty. By the way, the claw portion 13 is the gripping claw 9
For example, the upper end of the claw portion 13 may have a stopper projecting upward to prevent the claw portion 13 from falling off from the base 12 of the gripping claw 9. This can be achieved by a well-known structure such as making the abutment contact the upper end of the base portion 12 of the gripping claw 9 when the gripper slides downward beyond the range.

〔Effect of the invention〕

In summary, the present invention is provided with a horizontal moving means capable of horizontally moving the panel gripping device between the conveyor end conveyor that can be lifted and lowered and the lifting lifter. Although the panels can be stacked at a substantially constant position, the structure of the gripping device can be simplified, and the claw portion that is pressed against the panel against the base of the gripping claw of the gripping device can be stacked in the vertical direction. Because it is slidable, in other words, the panel is gripped by the gripping claw and transported above the lifting lifter, and the lifting lifter is raised to place the panel on the gripping device side on top of the panel loaded on the lifting lifter. For loading, it is best to separate the opposing gripping claws of the pick device to coincide with the rise of the lifting lifter, but such control is difficult and expensive to achieve with precision; In the present invention, since the part of the claw that is pressed against the panel against the base of the gripping claw can be slid vertically, even if the timing for separating the gripping claw is delayed from the timing for raising the vertical lifter, The claw part of the claw can move upward relative to its base while holding the panel, and even if there is a delay in control timing, there is no damage to the gripping claw side, that is, the gripping device side, and horizontal movement is possible. There is an advantage that panels can be loaded on the lifting lifter side that is raised from the gripping device.
