Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Field of Application) The present invention relates to a device for positioning objects to be transported by a roller conveyor in a fixed position.

(Prior Art) For example, the surface of lightweight aerated concrete panels (hereinafter referred to as ALC panels) is painted. This coating is performed by transporting the ALC panels one by one into a coating booth. That is, the ALC panels sent in a stack from the previous process are sucked up one by one using, for example, a vacuum suction device and placed on a roller conveyor, and the ALC panels are sequentially carried into a coating booth by the roller conveyor, for example. The paint is sprayed using a spray gun.

(Problem to be Solved by the Invention) The ALC panels sent in a stack from the previous process are not neatly aligned with their end faces one by one, and are in a scattered state. ALC in such a state
When a panel is sucked up by a vacuum suction device and placed on a roller conveyor, the position of each ALC panel on the roller conveyor is different, and in some cases, the ALC panel is placed diagonally and one corner of the ALC panel is placed on the roller conveyor. It may protrude outward. If transported in this condition, the ALC panel may collide with other equipment installed near the roller conveyor, or the side edge of the entrance of the paint booth, which is made small to prevent paint from flowing out, may collide with other equipment installed near the roller conveyor. or collide with other parts.

ALC panels generally have low impact resistance and will break or chip if they collide with other equipment, so it is highly desirable to be able to transport ALC panels by placing them at a fixed position on a roller conveyor. There is.

The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to provide a positioning device for a transported object that can be transported by a roller conveyor while the transported object is positioned at a fixed position.

[Structure of the Invention (Means for Solving the Problems)] In order to achieve the above object, the conveyed object positioning device of the present invention has the following features: A supporting means is provided which is movable up and down between a position protruding upward from the top and a position recessed below, and supports the conveyed object in a state where it floats from the roller conveyor by rising to the protruding position. , a moving means is provided for moving the conveyed object in a direction perpendicular to the direction of conveyance by the roller conveyor in a state where the conveyed object is supported by the support means, and a stopper means is provided for stopping the conveyed object moved by the moving means at a fixed position. It has been established.

(Function) The conveyed object is moved by the support means raised to the protruding position.
It is supported floating above the roller conveyor. In this state, the object to be conveyed is moved by the moving means in a direction perpendicular to the conveying direction of the roller conveyor, and when it is moved to a predetermined position, it is stopped there by the stopper means. Thereafter, when the lifting means descends, the object to be conveyed is supported by the rollers of the roller conveyor and conveyed by the roller conveyor.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings, in which it is applied to a case where an ALC panel is transported into a coating booth by a roller conveyor.

First, the ALC panels 1 sent in a stacked state from the previous process are placed on the side of the roller conveyor 2, as shown in FIG. The ALC panels 1 are then sucked up by a vacuum suction device (not shown) and placed one by one on a roller conveyor 2. The ALC panels 1 are carried into a coating booth 3 by the roller conveyor 2, and are sprayed with a spray gun to be painted. Ru.

As shown in FIGS. 1 and 2, the roller conveyor 2 has a large number of rollers 5 arranged in parallel at equal intervals between a pair of side frames 4, 4, and each roller 5 is driven by a motor (not shown). 3
It is rotationally driven via a transmission chain device 6 also shown in the figure. A support means 7 for supporting the ALC panel 1 in a floating state from the rollers 5 is provided in a portion of the roller conveyor 2 where the ALC panel 1 sucked up by the vacuum suction device is lowered. As shown in FIGS. 1 to 3, this support means 7 is constructed by providing a plurality of rows of wheels 9 (1'4) on an elevating frame 8 located below the rollers 5. The roller wheels 9 are located between the rollers 5 of the roller conveyor 2, and the elevating frame 8 is raised and lowered by a hydraulic cylinder 10.The elevating frame 8 is always kept in a horizontal state by a link mechanism 11. When the elevating frame 8 is in the lowered position, the roller 9 is sunk below the top of the circumferential surface of the roller 5, as shown by the solid line in FIG. When the elevating frame 8 is raised, it protrudes above the top of the circumferential surface of the roller 5 as shown by the two-dot chain line. base part 12 fixed to
Since the leg portion 13 supporting the wheel 9 is originally capable of rotating within a range of 360 degrees, the free rotation of the leg portion 13 is restricted by a restraining member 14 made of metal wire to prevent the wheel 9 from rotating freely. The axis of rotation is always kept substantially perpendicular to the axis of rotation of the roller 5.

On the other hand, on one side of the part of the roller conveyor 2 where the ALC batnel 1 sucked up by the vacuum suction device is unloaded, there is an AL supported on the wheels 9 as described later.
A moving means 15 is provided for moving the C panel 1 in a direction perpendicular to the conveying direction of the roller conveyor 2, that is, in the direction shown by arrow A in FIGS. 1 and 2. This moving means 15 is constructed by attaching a pressure plate 18 that comes into contact with the side surface of the ALC panel 1 to a rod 17a of an air cylinder 17 provided on a support frame 16. Suppression plate 18
A wheel 19 and a guide bar 20 are attached to both sides of the wheel 19, and by supporting the wheel 19 on the rail 21, the rod 17a is prevented from bending downward due to the weight of the pressing plate 18, and the guide bar 20 is held in place by the bush. By inserting and supporting the press plate 22, even if the press plate 18 hits the ALC panel 1 unevenly, it does not tilt with respect to the rod 17a. With respect to such a moving means 15, on the other side of the roller conveyor 2 there is an A moving in the direction of the arrow A.
A stopper means 23 is provided for stopping the LC panel 1 at a fixed position. This stopper means 23 is constituted by a plurality of support members 25 mounted on a fixing bar 24 mounted on the side frame 4 of the roller conveyor 2, and a roller 26 arranged in a vertical shaft shape. The rollers 5 of the roller conveyor 2, the rollers 9 of the support means 7, the rollers 26 of the stopper means 23, and the pressing plate 18 of the moving means 15 are each lined with urethane to prevent them from damaging the ALC panel 1. I have to.

Next, the operation of the above configuration will be explained.

The roller 5 of the roller conveyor 2 is constantly rotationally driven by a motor (not shown), and the ALC panel 1 placed on the roller 5 is automatically conveyed toward the coating booth 3 by the rotation of the roller 5. It has become.

Now, from now on, we will move ALC panel 1 to roller conveyor 2.
1, the lifting frame 8 of the support means 7 is pushed up by the hydraulic cylinder 10, and as a result, the rolling wheels 9 protrude upward from the top of the circumferential surface of the roller 5, as shown by the two-dot chain line in FIG. rise to the specified position. In this state, the AL stacked on the side of the roller conveyor 2
The C panel 1 is sucked up by a vacuum suction device (not shown), and is conveyed to just above the roller conveyor 2 and lowered. This descending ALC panel 1 is
protrudes above the top of the circumferential surface of the roller 5, so that it is placed on the roller 9 and is supported by the roller 9 in a floating state from the roller 5. When the ALC panel 1 is supported by the wheels 9, the air cylinder 17 of the moving means 15 moves the pressing plate 18 in the direction of arrow A. Due to this movement, the pressing plate 18 comes into contact with one side of the ALC panel 1 on the wheel 9 and pushes the ALC panel 1 in the direction of arrow A. Then, the ALC panel 1 moves along with the rotation of the wheel 9.
The stopper means 2 is moved in the direction of arrow A, and when the stopper means 2 is moved to the fixed position, as shown by the two-dot chain line in FIG.
It comes into contact with the roller 26 of No. 3 and stops.

When the ALC panel 1 is stopped at a fixed position by the rollers 26 in this way, the air cylinder 17 subsequently moves the suppression plate 18 in the reverse direction of arrow A, which is the backward direction.
The pressing plate 18 is separated from the ALC panel 1 and returned to its original position. Next, the elevating frame 8 of the support means 7 is lowered by the hydraulic cylinder 10, thereby lowering the roller 9 to a position below the top of the circumferential surface of the roller 5, as shown by the solid line in FIG. Then, as the roller 9 descends, the ALC panel 1 also descends, and on the way, the roller 5
It is lowered upward, and the support by the rollers 9 is changed to the support by the rollers 5. The ALC panel 1 transferred to the support of the roller 5 is moved toward the painting booth 3 side by the rotation of the roller 5 while maintaining the position set by the roller 26 of the stopper means 23 in the width direction of the roller conveyor 2. transported towards. When the ALC panel 1 is conveyed toward the coating booth 3, the elevating frame 8 of the support device 7 rises in order to convey the next ALC panel 1 to the roller conveyor 2, and the above-mentioned operations are repeated. The ALC panels 1 are transported one by one toward the coating booth 3, and the ALC panels 1 are coated with a spray gun (not shown) while passing through the coating booth 3.

Incidentally, in the above embodiment, the moving means 15 is an air cylinder 17.
and a suppression plate 18, which is a support t47 means 7.
The ALC panel may be moved by replacing the rollers 9 with "rollers" and rotating the "rollers" with a motor via a transmission chain device. In addition, transportation means include electric drives such as motors, cylinders, etc.
The mounting base of the wheel 9 may be tilted toward the stopper means 23 so that the object placed on the wheel 9 moves toward the stopper means 23 by its own weight, without a driving source. Furthermore, although the above embodiment has been described as being applied to the case of positioning an ALC panel, the present invention is not limited to this and can be widely applied to the case of positioning an article to be transported by a roller conveyor in a fixed position.

[Effects of the Invention] As explained above, according to the conveyed object positioning device of the present invention, the conveyed object is supported by the supporting means in a state where it is lifted from the rollers of the roller conveyor, and the non-transferred object is moved in this state. By means of a structure in which the conveyed object is moved in a direction perpendicular to the conveying direction by the roller conveyor, and the conveyed object is stopped at a fixed position by the stopper means,
The object to be transported can be transported while being positioned at a fixed position in the width direction of the roller conveyor. Therefore, there is no risk of colliding with other devices installed on the side of the roller conveyor during conveyance, and the positional relationship with the device for processing the conveyed objects sent by the roller conveyor is also improved. It can be set at an appropriate position, and has excellent effects such as eliminating the need for position correction by the operator.
