It is possible.

[Background technology and its problems] In general, to manufacture architectural panels, after a core material is framed, face materials are glued and nailed to the front and back sides of the core material, dried, and the outer periphery and openings are shaped as appropriate. It is used for cutting, etc. In this manufacturing line for architectural panels, panels are rotated in a horizontal plane or flipped in a vertical plane as necessary, but conventional flipping devices for flipping panels have various problems. Ta.

That is, in conventional reversing devices, a crane is used to reverse the panel, or a cylindrical body having a center of rotation is provided on the pass line so that the position of the flow of the panel in the horizontal plane, that is, the path line, is not changed before and after the reversing device. , the panel is carried in from the radial direction of this cylindrical body toward the center of the cylindrical body,
This cylindrical body is rotated 180 degrees for each panel to invert the panels. However, in the former method using a crane, there are problems in that the work efficiency is extremely low and it is dangerous.On the other hand, in the latter method, the pass line is not very high from the ground, so the rotation of the cylindrical body The problem is that bits (concavities) must be dug in the ground, and when changing the layout of the production line, the bits must be dug and backfilled each time, resulting in extremely low flexibility in changing the line. There is a point.

[Object of the Invention] An object of the present invention is to provide a construction panel reversing device that is easy to incorporate into a production line, has sufficient work efficiency, and has extremely high flexibility in changing the line arrangement.

As the reversing cylinder 62 is driven, a pinion 65 is rotated via a recess 64, so that the rotating frame 20 can be reversed. At this time, the stroke of the first reversing cylinder 62 is set to be a necessary and sufficient stroke for the pinion 65 rotated by the rack 64 to rotate exactly 180 degrees.

In addition, in the figure, 81 is a control box for controlling each drive mechanism, 82 is a carry-in side conveyor provided adjacent to the main body frame 1, and 83 is a control box provided adjacent to the main body frame 1 on the opposite side of the carry-in side conveyor 82. This is the unloading conveyor.

Next, the operation of this embodiment will be explained.

When carrying the building panel 70 into the reversing device, the piston rod 11 of the lifting cylinder 10 and the reversing cylinder 6
The two piston rods 63 are each in an advanced state, and the rotating frame 20 is in a lowered position and in a horizontal state. As a result, the upper surface of the second roller group 23 is made to be substantially on the same plane as the upper surfaces of the rollers of the carry-in conveyor 82 and the carry-out conveyor 83, and the pass line of the construction panel 70 is made to be in a straight line. has been done. Also, at this time, the piston rod 43 of the suppression cylinder 42 and the piston rod 52 of the stopper drive cylinder 51 are each brought into a contracted state, and the first... It is arranged so that it does not get in the way of being carried between the second roller groups 22 and 23. Further, the motor 30 is driven by the time the building panel 70 is carried into the rotating frame 20, and the building panel 70 carried in from the carrying-in conveyor 82 side can be taken into the rotating frame 20. ing.

Architectural panels 7 being moved on the carry-in conveyor 82
0 is carried into the rotating frame 20, the motor 3
The construction panel 70 is pulled onto each roller of the second roller group 23 that is driven via the drive chino 29 etc. that is driven by the drive of the construction panel 70 in the rotating frame 20. When the rotation frame 2 is moved to a predetermined position and this movement is detected by a detection means (not shown), the drive of the motor 30 is stopped and the rotation frame 2 is moved to a predetermined position.
Architectural panel 70 is located within 0.

Next, the pressing cylinder 42 of the suppressing means 40 is driven,
Each pressing body 44 is advanced toward the architectural panel 70 side,
The construction panel 70 is moved to one side, that is, by the lower second roller group 23.
to suppress and fix. Along with this, the panel fall prevention mechanism 50
The stop 7 drive cylinder 51 is also driven in the advancing direction, the lever 54 is rotated clockwise, and the rotating shaft 55 is rotated accordingly.
The stopper 56 is also driven clockwise via the stopper 56, and its tip is positioned so as to close the gap formed between the first and second roller groups 22,23.

Next, the piston rod 11 of the lifting cylinder 10 is contracted, and the rotating frame 20 is moved to the raised position shown by the chain line in FIG. 1 and stopped, and in this stopped state, the reversing cylinder 62 of the rotating drive mechanism 60 is driven, When the piston rod 63 is in the contracted state, the rack 64 drives the pinion 65, and the rotating frame 20 is rotated 180 degrees counterclockwise, that is, with the stopper 56 facing downward, via the central shaft 21, and then stopped. Ru.

When the rotation of 180 degrees, that is, reversal of the rotating frame 20 is completed, the piston rod 11 of the elevating cylinder IO is driven in the advancing direction, and the rotating frame 20 is lowered via the slide frame 4, and is located at the lower side due to the reversal. The upper surface of each roller of the first roller group 22 is aligned with the upper surface of the rollers of the carry-in conveyor 82 and the carry-out conveyor 83, that is, the pass line is aligned in a straight line. In this state, the pressing cylinder 42 of the pressing means 40 is driven in the contraction direction, and the building panel 7 supported by each pressing body 44
0 is the 117th) roller group 22 due to the reduction of the pressing means 40.
It is then transferred to the top and ready for removal. Further, the stopper drive cylinder 51 of the panel drop-off prevention mechanism 50 is also driven in the contraction direction, and the stopper 56 is moved in a direction that does not close the gap between the first and second roller groups 22 and 23. In this state, the motor 30 is driven and the first roller group 22 is rotated via the driving chino 29.

The construction panels 70 are moved in the carry-out direction and are sequentially transferred to the carry-out side conveyor 83 to complete the carry-out.

When the reversal of one construction panel 70 is completed in this way, the construction panel 70 is again carried into the rotating frame 20 from the carry-in side conveyor 82, but at this time the rotating frame 20 is in the state shown in FIG. Since the rotating frame 20 is in a 180 degree reversed state, the reversing operation of the rotating frame 20 is performed by the reversing cylinder 6.
When the second piston rod 63 is advanced, it is rotated clockwise in the opposite direction to that described above, and the movement of the other elevating cylinders 10 and the like are performed in substantially the same manner.

Thereafter, the construction panel 70 is continuously reversed while the rotating frame 20 is alternately reversed by 180 degrees in the same manner.

According to this embodiment as described above, since the rotating frame 20 holding the construction panel 70 is reversed at a position elevated from the pass line, there is no need to dig a pit on the floor of the factory, etc. The reversing device can be easily relocated in the design direction, etc., and therefore the flexibility of line changes can be set high. Further, the construction panel 70 is pressed by the pressing means 4.
Since the construction panel 70 is rotated while being pressed against one of the roller groups, that is, the second roller group 23 side, the construction panel 70 can be reliably held, and there is no risk of the construction panel 70 falling off. 1. Even when the construction panel 70 moves in the falling direction, the rotating direction of the rotating frame 20 is such that the side where the gap between the first and second roller groups 22 and 23 is closed by the stopper 56 is the lower side. Since the building panel 70 is rotated in a single rotation, there is no risk of the building panel 70 falling off from the frame 20. At this time, the building panel 70 is not pressed by moving the first roller group 22. , there is less risk of the architectural panel 70 slipping and falling off, and the structure can be simplified. Furthermore, since the reversal direction of the construction panel 70 is such that the loading side and the unloading side of the construction panel 70 are reversed on the pass line along the feeding direction, the line configuration on the straight line is not obstructed. Can be reversed in less space. At this time, since the architectural panel 70 is generally flowed in the longitudinal direction, the width is approximately constant, and the length in the longitudinal direction varies depending on the specifications.
If the length of 0 is set to the length of the longest architectural panel 70, the width direction of the one-rotation frame 20 will always be constant, making it easy to set up the production line and improve efficiency from this point of view. can produce good quality products. In addition, first and second roller groups 2212 provided on the rotating frame 20
3 is driven by the motor 30, the construction panels 70 can be easily carried in and out, and the carry-in conveyor 82 and the carry-out conveyor 83 provided at the front and rear of the device are simply roller conveyors or the like. can do. Further, a balance weight 15 is provided in each support column 2 of the main body frame 1 to balance the weight with the rotating frame 20, slide frame 4, etc., so that the load on the lifting cylinder 10 can be reduced, and The rotating frame 20 can be moved up and down smoothly.

In the embodiment described above, cylinders were used for lifting, lowering and rotating the rotary frame 2O, suppressing the building panel 70, driving the rotation of the stopper 56, etc.

The present invention is not limited to this, and a drive means such as a motor may be used. In addition, if the pressing means 40 sufficiently clamps and fixes the building panel 70, the panel fall prevention mechanism 50 It is not necessary to provide this, but if you do, you can ensure greater safety. Further, in the embodiment described above, the rotating frame 20 is first pulled up to a predetermined position and then rotated, but the rotating frame 20 may be started at the same time as being driven, and this case has the advantage that manufacturing efficiency can be further improved. There is. Moreover, if the carry-in side conveyor 82 and the carry-out side conveyor 83 provided before and after the reversing device are other carry-in and carry-out devices such as forklifts, the first and second roller groups 22 and 23 of the rotating frame 20 are not necessarily driven. You don't have to, but first. Second roller group 22
．． If 23 is driven, there is an advantage that loading and unloading is easy as described above.

[Effects of the Invention] As described above, according to the present invention, it is possible to provide an architectural panel reversing device that can be incorporated into an integrated production line for architectural panels and has high flexibility in changing the line.
