Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel material reversing device used for stacking a plurality of panel materials such as building sizing panels and binding and packing the panel materials.

Conventionally, a panel material P such as a sizing panel for construction is generally stacked in units of a fixed number, for example, 8, 10, 12 or the like, which is convenient for handling, and is bundled for packing. (Fig. 4). Such panel material P
Has a uniform cross-sectional shape in the direction of its long side, but often has a modified cross-section with different thicknesses t1 and t2 in the direction of its short side. Since nt1 and the other are nt2, which are extremely deformed, not only is it inconvenient to handle, but it also causes an unexpected accident due to a load collapse.

Therefore, after stacking n / 2 sheets out of the n sheets, next, the panel material P is reversed and the remaining n / 2 sheets are stacked upside down. Together with
(T1 + t2) · n / 2, and a stable rectangular cross-section package is obtained.

In the panel material manufacturing plant, the reversing and stacking work of the panel material P is conventionally performed only by hand, which is not only inefficient but also burdens the operator in calculating the number of sheets. Because of the imposition, the problem of being forced to carry out troublesome work with a large mental burden was unavoidable.

OBJECT OF THE INVENTION The object of the present invention is to provide a novel panel material reversing device that can be incorporated into a continuous panel material production line to automatically perform a panel material reversing operation in view of the circumstances of the prior art. To provide.

Configuration of the Invention According to the configuration of the present invention for achieving the above object, the first and second rotating arms are provided on the upstream side and the downstream side of the flow of the panel material, respectively, and the former is a horizontal position downstream. To the side 9
At an angle of 0 degrees or more, the latter is 90 degrees upstream from the horizontal position.
It can be rotated at an angle of less than 90 degrees
The panel material conveyed while being turned over on the upper surface of the first rotating arm is transferred to the upper surface of the second rotating arm that is erected to rotate upward at an angle of less than or equal to 5 degrees. By returning both rotating arms to the horizontal position, the panel material can be reversed, and a vertically movable stopper is provided between the two rotating arms so that the above-mentioned operation can be performed only when the reversing operation is necessary. The gist of the invention is to raise the stopper so that the flow of the panel material can be stopped at a predetermined position.

The auxiliary devices including 1 ... Are arranged to constitute a part of the continuous manufacturing apparatus for the panel material P.

The conveyors 21, 21, ... On the upstream side of the reversing device are a plurality of belt conveyors arranged side by side in the longitudinal direction of the panel material P, and on the upstream side, all the conveyors centering on the downstream drive roller 21a. It is possible to swing up and down all at once (1st
The height of the upper conveying surface can be set by switching between a position higher and a position lower than the upper surface of the fixed roller conveyors 22, 22 ...

The first rotating arms 11, 11 ... Provided on the upstream side are made of a plurality of rod members each having one end fixed to a rotating shaft 11b that is rotated by an air torque actuator 11a. , Are provided so as to be located between the translating conveyors 21, 21 ... (FIG. 2). Each rotating arm 11
Can be rotated in the range from the horizontal position to the standing position of 90 degrees or more downstream by the rotation of the rotation shaft 11b (Fig. 1). It is designed to be lower than the upper conveying surface of the conveyors 21, 21 ...

The second rotary arms 12, 12 ... Provided on the downstream side have one end fixed to a rotary shaft 12b driven by an air torque actuator 12a, just like the first rotary arms 11, 11. However, the rotation range of the first rotation arms 11 and 11 is
Keep it within an angle range of 90 degrees upstream from the horizontal position so as not to intersect with. The relationship between the second rotary arms 12, 12 ... And the transport conveyors 31, 31 ... follows the relationship between the first rotary arms 11, 11 ... And the transport conveyors 21, 21.

The first rotating arms 11, 11 ... And the second rotating arms 12, 12 ...
Stoppers 13, 13 ... Are arranged in the middle of
All the stoppers 13, 13 ... Can be moved up and down in one movement by an air cylinder (not shown). The height of the stopper 13 is such that the conveyer 21,
It is possible to go over the height of the upper transport surface of 31 and descend at least below it in the lowered position.

A stopper 32 is provided at the downstream end of the conveyors 31, 31 ...
Is provided, and the stoppers 32 are used to convey the conveyors 31, 3
The movement of the panel material P transported on the upper transport surface of 1 is prevented, and the suction pads 33a, 3a that can move up and down are provided above the stop position of the panel material P.
A stacker device 33 having 3a is provided.

The stacker device 33 adsorbs the panel material P on the conveyors 31, 31 ... With the suction pads 33a, 33a ... And reciprocates the rail 33b as a whole to convey the panel material P onto the roller conveyor 34. Then, the panel material bundle P'can be formed thereon by stacking. That is, the suction pads 33a, 33a ... Are dropped onto the panel material P stopped by the stopper 32 to attract the same, and the suction pads 33a, 33a. 33b, suction pads 33a, 3
After lowering 3a ..., the suction is released to remove the panel material P.
After stacking, it returns to the original position. Here, it is assumed that a plurality of suction pads 33a, 33a, ... Are installed in consideration of the size and weight of the panel material P to be sucked, and it is sufficient if all of them perform upward and downward movements at the same time. .

The operation of a series of equipment having such a configuration is as follows.

The panel material P is cut to a predetermined size in a preceding step of a continuous manufacturing apparatus (not shown) and is carried in a completed state from a direction of an arrow A in FIGS. 1 and 2 through a conveyor device (not shown). At this time, the upstream transfer conveyor 21,
21 ..., the upstream side thereof is in the lowered position (two-dot chain line in FIG. 1), the rotating arms 11, 11, ..., 12, 12 ... Stand by in the horizontal position (solid line in the same figure), and the stopper 13 , 13 ...
Is in the ascending position (two-dot chain line in the figure).

Since the transport conveyors 21, 21 ... Are in the lowered position, the loaded panel material P is first fixed to the fixed roller conveyor 2.
2, 22, ... Placed on top and stopped.

In this state, when the conveyors 21, 21, ... Are started and raised, the panel material P on the roller conveyors 22, 22, ... Is conveyed on the upper conveyor surface of the conveyors 21, 21 ,. Are stopped at the position where they come into contact with the stoppers 13, 13 ..., This position is above the first rotating arms 11, 11 ... In the horizontal standby position (FIG. 1, FIG. 2, FIG. FIG. 3 (B)). Therefore, the transport conveyors 21, 21 ... Stop and take the lowered position again to prepare for the next transport of the panel material P.

The operation of the panel reversing device will be described below with reference to FIG.

When the front end of the panel material P comes into contact with the stopper 13 and stops (hereinafter, referred to as (BB) in the figure), the transport conveyor 21 stops as described above. Subsequently, the stopper 13 descends, and then the air torque actuator 12
a is driven, and the second rotation arm 12 starts to rotate upright toward the upstream side (C). Further, the first rotating arm 1 is provided with an appropriate time interval from the start of the rotation of the second rotating arm 12.
1 starts standing rotation toward the downstream side. The rotation of the first rotation arm 11 is performed by the air torque actuator 11a.
Driving by is similar to the case of the second rotating arm 12. The air torque actuators 11a and 12a used as the drive sources of the rotating arms 11 and 12 have little internal loss at the time of starting, and therefore, there is no possibility of causing an excessive temperature rise even when performing intermittent motion. Suitable for such applications.

When the first rotating arm 11 rotates and its upper surface exceeds the height of the upper conveying surface of the conveyer 21, the panel material P placed and stopped on the upper conveying surface makes a first rotation. It is lifted by the arm 11 and rotates together with it according to the rotating motion, and is turned over. At this time, the front end of the panel material P is on the upper end surface of the stopper 13 that is descending, and becomes the center of the reversing and rotating motion of the panel material P itself.

When the turning angle of the first turning arm 11 exceeds 90 degrees, the panel material P falls down toward the second turning arm 12 by its own weight (D). The second rotation arm 12 is capable of standing rotation up to a predetermined angle of 90 degrees or less, which corresponds to the maximum rotation angle of the first rotation arm 11, and the start timing of the rotation is Since it is ahead of that of the first pivot arm 11, the second pivot arm 1 is already in motion when the panel material P falls down by its own weight.
2 has reached a predetermined maximum rotation angle. Therefore,
Since the angle range in which the panel material P falls is extremely small, an excessive impact is applied to the panel material P at this time,
The panel material P can be smoothly transferred from the first rotating arm 11 to the second rotating arm 12 without the possibility of generating a large impact sound.

Then, the first and second rotating arms 11 and 12 are returned to the horizontal position by driving the air torque actuators 11a and 12a (E), but the panel material P is moved to the second rotating arms 12 and 12. When the upper surface of the second rotating arm 12 reaches below the upper transfer surface of the transfer conveyor 31, the reverse operation is continued while being supported by the upper surface of the transfer conveyor 31. Will be placed.

Then, the conveyor 31 is started to convey the panel material P (F), and the stopper 13 is raised to prepare for the next panel material P reversing operation.

Note that FIG. 3 (A) shows the mutual positional relationships among the conveyors 21, 31, the rotating arms 11, 12, and the stopper 13, and in FIGS. 3 (B) to (F), Illustration of the transfer conveyors 21 and 31 is omitted.

When the inverted panel material P transported by the transport conveyors 31, 31, ... Abuts the stopper 32 (FIG. 2), the transport conveyor 31 is stopped and the stacker device 33 is started to transport the panel material P to the roller conveyor. The sheets are conveyed one by one onto 34 and piled up. When the stacking of a predetermined number of panel materials P is completed, the panel material bundle P'is carried out in the direction of the arrow B and transferred to the next step (for example, a binding step).

In the above description, the case in which the panel material P needs to be inverted between the conveyors 21 and 31 is described. However, when the panel material P does not need to be inverted, the conveyor 2
When the panel material P is conveyed by 1, the stopper 13 may be placed in the lowered position and the conveyor 31 may be operated at the same time. As a result, the panel material P does not come into contact with the stopper 13 and is thus inverted. Can pass through the device, and thus without being inverted
It is transported to the position of the stopper 32 at the downstream end of the transport conveyor 31.

Therefore, when making a panel material bundle P'consisting of n panel materials P, a panel counter (not shown) is used to perform an inversion operation for the first n / 2 sheets and for the other n / 2 sheets. By controlling so as not to invert, the predetermined panel material bundle P'can be obtained. However, it is arbitrary whether the n / 2 panel materials P to be reversed are the first n / 2 of the n sheets or the second n / 2 of the n sheets. Further, in some cases, it is possible to easily stack the inverted and non-inverted sheets one by one alternately.

EFFECTS OF THE INVENTION As described above, according to the present invention, two sets of rotary arms and stoppers are provided in the flow of the panel material, and the rotary arms are controlled to rotate, whereby the panel is smoothly moved. Since the material can be turned over, and whether the turning operation is performed or not can be switched by controlling the stopper to move up and down, it can be installed in a continuous panel material production line and the panel material turned over as necessary. There is a new and excellent effect that can be automatically performed.

Further, in the 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. By making it move, the angle range in which the panel material falls due to its own weight can be made very small, so there is also an excellent effect that there is no danger of giving an excessive impact to the panel material during the reversing operation. .
