Description

The present invention relates to a panel reversing device capable of efficiently reversing a panel by 180 degrees.

[Conventional technology]

2. Description of the Related Art In recent years, a panel construction method has been widely used in which panels having surface materials attached to the front and back of a frame are used to form walls, floors, roofs, etc. of houses.

For example, such a construction panel needs to be turned upside down 180 degrees in the production process such as attaching a face material to the lower surface and attaching a sash. In addition to such panels for construction, also for panels such as steel plates and glass plates,
It is sometimes flipped over to inspect the front and back.

When reversing such a panel, the conventional method shown in FIG.
As shown in (a) and (b), the panel P was inserted into the passage b open at one end of the rotating body a, and the rotating body a was inverted by 180 degrees.

[Problems to be Solved by the Invention]

However, in such a reversing device, in order to invert the panel P again, the reversing body a must be rotated 180 degrees with an empty load, which causes a loss in working time during that time.
It was inefficient.

There is also a problem in that the panel P rattles and the panel P is damaged during the reversal due to the gap g generated between the passage b and the panel P.

It is an object of the present invention to provide a panel reversing device that eliminates rotation in an empty state and can efficiently invert a panel.

[Means for Solving the Problems]

According to the present invention, the rotary plates are arranged coaxially and face each other, and the passages are fixed to the connecting frame connecting the rotary plates and extend in a direction perpendicular to the axis of rotation and open at both ends through which the panel faces. And a pressing rod that is arranged at both ends of the passage and that can move between a closed position that blocks the passage and an open position that opens and that has a pressing portion that protrudes outward in the radial direction. A reversing machine body that can be stopped in each direction in which the passage is horizontal, and a holding rod having a pushing piece that is provided at both sides of the passage of the reversing machine body and that pushes the pressing portion and moves the holding rod to the open position. The pressing rod comprises an actuator and is guided and moved by guide shafts arranged in a direction orthogonal to the passage at opposite surfaces of the rotary plate and both ends of the passage, and the pressing rod is moved to the closed position. Urged towards Constantly the example rod is panel turning device comprising comprising a spring means for closing the passage.

[Action]

In the main body of the reversing machine, a passage through which the panels whose both ends are open is formed on the surfaces facing each other. Further, both ends of the passage are opened and closed by a holding rod urged by spring means. This presser bar
Opening and closing operations are performed sequentially by a presser bar actuator installed on the reversing machine body. Therefore, the passages can be sequentially opened and closed at the carry-in end and the carry-out end, so that there is no rotation in the empty state, and the work efficiency is improved.

Further, since the presser bar is operated by the spring means and is operated by the presser bar actuating machine outside the reversing machine body, the rotating reversing machine body can omit the operating device for the operation of the presser bar, and the piping and wiring. , And the structure of the device is simplified to reduce breakdowns. Further, the spring means for urging the pressing rod toward the closed position can press the panel by the pressing rod during reversing, and at that time, there is no impact due to the movement of the center of gravity at the time of reversing and damage to the panel or the like can be prevented.

In this way, after the panel P is carried out, the panel P can be inserted without rotating the rotary plate 5.

Further, since the panel P is pushed upward by the spring means 17 during the rotation, there is no rattling when the center of gravity is moved due to the gap, and it is possible to prevent the panel from being damaged by reducing the impact.

It should be noted that the passage A should be able to be pushed up by the spring means 17.
Is preferably smaller than the panel P.

Further, in the device 1 of the present invention, various modifications can be made such as using an appropriate belt type as the carry-out body.

〔The invention's effect〕

Both ends of the passage between the carriers of the reversing machine body are opened and closed by a holding rod urged by spring means. Therefore, the passages at the carry-in end and the carry-out end can be opened and closed sequentially, and therefore, there is no rotation in the empty state, and work efficiency is improved.

Further, since the presser bar is operated by the spring means and by the presser bar actuator outside the reversing machine body, the rotating reversing machine body can be omitted from the actuator for the operation of the presser bar.
Wiring and device structure can be simplified and breakdowns can be reduced. Also, by the spring means for urging the pressing rod toward the closed position,
The panel can be pressed by the pressing rod when it is turned over, and there is no impact due to the movement of the center of gravity at the time of reverse, and the panel etc. can be prevented from being damaged. Further, the holding rod is moved to be guided by guide shafts arranged in a direction orthogonal to the passage at opposite surfaces of the rotary plate and at both ends of the passage to prevent the holding rod from moving in the panel carrying-out direction. A certain strong holding rod can securely hold the panel when it is turned over, and the risk of dropping the panel can be significantly reduced.
