Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a panel material reversing device used for stacking a plurality of panel materials, such as architectural roof panels, and bundling them together for packing.

Prior Art Panel materials such as architectural roof panels are generally stacked in a certain number of panels, such as 8, 10, or 12 panels, for convenient handling, and then bundled and packaged. It is. Such panel materials have a uniform cross-sectional shape in the long side direction, but
In the direction of its short side, it often takes an irregular cross section with different thicknesses t1 and t2, and when n sheets of such a thing are stacked, the entire cross section becomes extremely irregular, with one being nt1 and the other being nt2. Therefore, it is not only inconvenient to handle, but also causes unexpected accidents due to cargo collapse.

Therefore, after stacking n/2 of the n units, the next step is to flip the panel material and stack the remaining n/2 panels upside down. According to this method, the above dimensions are , both of them are (t1+t2·n/2), and a stable rectangular cross-sectional packaging shape can be obtained.

In panel material manufacturing factories, this work of reversing and stacking panel materials has traditionally been done exclusively by hand, which is not only inefficient but also places a burden on workers in calculating the number of panels. As a result, the problem of being forced to perform tedious and mentally taxing work was unavoidable.

Purpose of the Invention In view of the actual state of the prior art, the object of the present invention is to provide a system that can be incorporated into a continuous production line for panel materials and automatically perform the reversing operation of panel materials.
An object of the present invention is to provide a novel panel material reversing device.

Structure of the Invention The structure of the present invention for achieving the above object is to provide a first stage for delivering and reversing the panel material to the upstream side and the downstream side of the flow of the panel material, respectively.
A rotating arm and a second rotating arm are provided, the former being able to freely rotate from the horizontal position to the downstream side at an angle of 90 degrees or more, and the latter being able to freely rotate from the horizontal position to the upstream side at an angle of 90 degrees or less. In addition, a stopper is provided at the base end of the first rotating arm, and when the first rotating arm stands up and rotates, the stopper is placed on the upper surface of the stopper and rotates up and down together with the first rotating arm. While preventing the panel material from falling off, the second rotating arm is provided with a base member whose proximal end side and distal end side are independently retractable from the upper surface of the second rotating arm. The panel material on the upper surface of the rotating arm of
The second rotating arm is transferred onto the base member that has been rotated upright together with the second rotating arm, and the second rotating arm is moved to the horizontal plane while preventing the panel material from slipping off by the panel locking portion that protrudes from the proximal end of the base member. By returning the panel material to the position shown in FIG. The gist of this is what you have achieved.

Example A panel material reversing device is a panel material P indicated by an arrow.
A first rotating arm 10 on the upstream side of the flow and a second rotating arm 20 on the downstream side are arranged facing away from each other along the flow of the panel material P. figure).

The first rotating arm 10 has four arms 11, 11 that are protruded from the base member 12 in parallel with the flow of the panel material P.
The base end member 12 is connected to a drive source 13 via a rotation shaft 13a, and each arm 11 is rotated at an angle of 90° or more (for example, 95°) from a horizontal position. Therefore, it is possible to stand up and rotate toward the downstream side.

The arms 11, 11... are connecting rods 11a, 11a...
They are assembled into two sets of two on the left and right with a distance between them, and their overall width is:
It is made to substantially match the full width of the panel material P (not shown).

A sprocket 1 fitted to the shafts 14b, 14b is provided at both ends of the arms 11, 11... and in the center gap.
Chain 1 driven by 4a, 14a...
A chain conveyor 14 is constructed by stretching 4c, 14c..., and each chain 1
The upper surface of the arm 4c is slightly higher than the upper surface of the arm 11 when it is in a horizontal position. Also, each arm 1
At the base end of the arm 11 are stoppers 15, 15, which are movable into and out of the upper surface of the arm 11 by a cam mechanism (not shown).
has been erected.

The second rotating arm 20 includes a base end member 22 disposed parallel to the base end member 12 of the first rotary arm 10, and arms 21, 21, . . . In the intermediate gap between each pair of two arms 21, 21,
Basically, it has substantially the same mechanism as the first rotating arm 10, except that base members 30, 30 driven by air cylinders 31, 31, . . . are also provided.
By the drive source 24 connected by the rotation shaft 24a,
Each arm 21 is rotatable upstream from its horizontal position at an angle of 90 degrees or less (for example, 85 degrees). In addition, similarly to the first rotating arm 10, the chain conveyor 22 and the stoppers 23, 2
3... are arranged.

The base member 30 includes air cylinders 31, 31
and the link mechanism 3 operated thereby.
2, 33, the proximal end side and the distal side thereof,
A plate body 3 that can freely appear and retract from the upper surface of the arm 21 independently of each other.
4 (FIG. 2), and a panel locking portion 34a is provided protruding from the upper surface of the base end side of the plate body 34. That is, the air cylinder 31 and the link mechanism 3
2. The air cylinder 31 and the link mechanism 33 form a vertical movement mechanism that moves the base end side and the distal end side of the base member 30 up and down, respectively.

A link mechanism 32 for vertically moving the base end side of the plate body 34 is connected to a mounting bolt 31b fixed to a bracket 31a on the back side of the arm 21, and to a piston rod 31c of an air cylinder 31 whose clevis portion is rotatably engaged. When pushing the link pin 32a,
One end slides horizontally in a long hole 32c provided in the bracket 32b, and the other end is connected to the plate 34 by a pin 32d.
A link piece 32 rotatably locked on the back side of
When e rises, the auxiliary link piece 32g, which is rotatably supported at one end on the pin 32f on the bracket 32b and at the other end on the link pin 32a, also rises, thereby causing the base end of the plate body 34 to rise. It is designed so that the upper part can be raised. When extending the piston rod 31c of the air cylinder 31,
The plate body 34 can protrude above the upper surface of the arm 21 (solid line in FIG. 2), and when the piston rod 31c is retracted, the panel locking portion 34 protruding from the plate body 34
The upper end surface of a can be sunk below the upper surface of the arm 21 (double-dashed line in the figure).

Link mechanism 3 that moves the tip side of the plate body 34 up and down
3 is slightly simpler than the link mechanism 32, and when the link pin 33a is pushed by the piston rod 31c of the air cylinder 31, the pivot points of the two link pieces 33b and 33c are pushed and both are aligned in a straight line. While extending, when the piston rod 31c is retracted, both are bent into a dogleg shape, thereby allowing the tip side of the plate 34 to move up and down.

The air cylinders 31, 31 that move the base end side and the distal end side of the base member 30 up and down can be controlled independently from each other, and therefore, the base member 3
Both ends of 0 can assume two states, upper and lower, independently of each other, without depending on the state of the other. Here, the strokes of the link mechanisms 32 and 33 are determined so that when the both ends of the plate 34 are made to protrude above the upper surface of the arm 21, the plate 34 and the arm 21 are parallel to each other. .

In addition, the arms 11, 11 of the first rotating arm 10, the stoppers 15, 15, . . . erected, and the arms 21, 21, .

... means, arranged in this order from top to bottom,
They are arranged so as to be able to support the lower end of the panel material P.

The operation of the panel material reversing device having such a configuration is as follows.

With both the first rotating arm 10 and the second rotating arm 20 tilted to the horizontal position, the stoppers 15, 15, . . . on the proximal end side of the arms 11, 11, .
...protrudes upward, and the second rotating arm 20
The base member 30 attached to the arm is sunk from the upper surface of the arms 21, 21, . . . and placed in a standby state. The stoppers 23, 23, . . . on the second rotating arm 20 side are kept in a protruding state.

In such a standby state, the chain conveyor 1
4, when the panel material P is carried onto the panel mounting surface consisting of the upper surface of the first rotating arm 10 (FIG. 4A), the panel material P is moved to the stopper protruding above the panel mounting surface. 15, 15..., and accurate positioning is possible, so the chain conveyor 14 is stopped at that point.

Next, the first rotating arm 10 is rotated by about 80 degrees and the second rotating arm 20 is rotated by about 85 degrees to make them both stand up (FIG. B). At this time, the panel material P also rotates and stands up together with the first rotating arm 10, but the stopper 1
Since its lower end is supported by 5, 15..., it will not slip off from the first rotating arm 10,
Therefore, the panel material P is in a state where it is propped up on the panel mounting surface of the first rotating arm 10. Further, the raising operation of the panel material P is performed by the first rotating arm 10.
Since the panel material P is pushed up while its entire surface is supported by the panel member P, the panel material P is smoothly raised up to a predetermined angle together with the first rotating arm 10.

The air cylinders 31, 31... are driven to cause the base member 30 to protrude above the arms 21, 21... (FIG. C). This operation may be performed in parallel with the raising and rotating operation of the second rotating arm 20, but in any case, before proceeding to the next step, the proximal end of the base member 30 and , it is assumed that the protrusion of the tip has been completed. In this state, the base member 30 is in parallel with the arms 21, 21, . . . as described above.

The first rotating arm 10 is further rotated to be approximately parallel to the second rotating arm 20 (D in the figure). The rotation angle of the first rotation arm 10 at this time is about 95 degrees from the horizontal position at the initial standby position. Panel material P
is almost held between the arms 11, 11... of the first rotating arm 10 and the base members 30, 30, but its lower end is still attached to the stopper 1.
5, 15..., and the panel locking portion 34a of the base member 30 is inserted below them (FIG. 3A).

By operating the driving air cylinder 31 of the link mechanism 33 that moves the distal end of the base member 30 up and down, the distal end of the base member 30 is sunk (FIG. 4E). At the same time, stopper 15, 15...
can be withdrawn. By the former operation, the panel material P
, since the upper support by the base member 30 is released, it falls to the side of the second rotating arm 20, while
By the latter operation, the lower support is moved to stopper 1.
5, 15... to the panel locking portion 34a of the base member 30, as a result, the panel material P
is transferred from the first rotating arm 10 onto the base member 30 by its own weight. At this time, the movement of the panel material P is such that the rotating direction follows the movement of the base member 30, while the falling direction is such that it only slides down the minute clearance 34b.
It is extremely smooth, and even if the panel material P is large and heavy, it can be performed with almost no impact.

When the first rotating arm 10 and the second rotating arm 20 are respectively rotated back to the horizontal position (FIG. F),
Since the panel material P is transferred together with the latter to a substantially horizontal position in an inverted state, the base member 3

(G in the same figure), and then the chain conveyor 2 on the second rotating arm 20 side.
2. Panel material P between this
Since the entire process of the movement is guided by the second rotating arm 20 and the base member 30, there is no impact, and there is no risk of vibration occurring in the panel material P.

In the above explanation, the stoppers 23, 23, etc. provided on the second rotating arm 20 do not contribute to the reversing operation of the panel material P in any way; Immediately after the process of transferring the panel material P from the movable arm 10 to the second rotary arm 20 (FIGS. 3B and 4E), the panel material P is transferred by sinking the proximal end of the base member 30. the lower end of the stopper 23,
23... (FIG. 3C), after which the two rotating arms 10, 20 can be returned to their original positions. Panel material P
When the panel material P is lightweight and small, the operation process can be simplified in this way, and in that case, the entire surface of the panel material P is placed on the upper surface of the second rotating arm 20. Since the panel material P is returned to the horizontal position, the chain conveyor 2
There is no problem even if 2 is operated continuously in advance, and therefore the cycle time can be shortened.

Furthermore, both the rotating arms 10 and 20 are placed in a horizontal position, and the stoppers 15, 15..., 23, 23
Chain conveyor 14, 22 with ... lowered
If the panel material P is operated, the panel material P will be conveyed through this reversing device without being subjected to a reversing operation, so it is possible to extremely easily switch and control whether or not the reversing operation of the panel material P is performed. .

Effects of the Invention As explained above, according to the present invention, two sets of rotating arms are provided in the flow of panel materials, and the rotation of each rotating arm is controlled. By folding and transferring the panel material from the rotating arm to the second rotating arm, the panel material can be smoothly reversed.Moreover, stoppers are provided at the base ends of both rotating arms, By controlling it up and down, it is possible to switch between reversing operations, so it can be incorporated into a continuous production line for panel materials and automatically perform reversing operations as needed. , has new and excellent effects.

Further, in the above-mentioned rotating arm, the first rotating arm on the upstream side rotates 90 degrees or more toward the downstream side, whereas the second rotating arm on the downstream side rotates 90 degrees or less toward the upstream side. At the same time, the second rotating arm is provided with a retractable base member, and the panel material is transferred from the first rotating arm to the second rotating arm via the base member. This allows almost the entire movement of the panel material to be guided by both rotating bowls and the base member, so there is no risk of impact on the panel material during the reversing operation. Therefore, even if the panel material is large and heavy, it can be turned over very smoothly, which is an excellent effect.
