DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for transferring a plate-like body such as a frame.

[0002]

2. Description of the Related Art Generally, wall panels are made of Japanese Utility Model Publication No. 56-21.
As described in Japanese Patent No. 967, it is formed by sticking a rectangular frame frame and a gypsum board integrally bonded with an aluminum plate.

By the way, in order to attach the frame to the gypsum board, it is necessary to sequentially transfer the frame in accordance with the gypsum board which is sequentially carried in. For this reason, the frame is manufactured in advance, Stack and stock
The sheets are transferred one by one toward the gypsum board side via the transfer device. That is, this transfer device is provided with a lifter that raises the frame frames stacked every predetermined number of sheets by the height of each frame, and a transfer that provides a plurality of engaging claws to transfer the uppermost frame frame. By operating the transfer means, the engaging claw is brought into contact with the uppermost frame frame that has been sequentially lifted to the set height via the lifter, extruded, and transferred to a position facing the gypsum board. Things.

[0004]

By the way, when the frame frames are stacked, the upper surface of the uppermost frame frame is
Originally, the height (regular height) represented by the product of the height of one frame frame and the number of stacked frames should match the horizontal plane formed parallel to the lifter. However, since the frame frame is formed by combining square pipe-shaped frames vertically and horizontally and welding the butted portions, the frame frame has slight dimensional errors due to distortion due to welding deformation and unevenness due to welding beads. Has occurred. Therefore, when such frame frames are stacked, the error is accumulated, and the top surface of the uppermost frame frame exceeds the regular height, and the degree of the crossing and its position are not uniform. The upper surface forms a twisted surface. When the engaging claw is moved by the transfer means in such a state, the engaging claw provided so as to move at a regular height may be located below the uppermost frame depending on the accumulated error. It will also be pushed out by contacting the frame frame located.

[0005] As a result, the operator must temporarily stop the operation of the transfer means and make a repair so as to transfer only the uppermost frame, which causes a problem that the productivity is reduced.

[0006] The present invention has been made in view of such problems, and when plate-like bodies such as a frame are stacked,
An object of the present invention is to provide a plate-like body transfer device that can reliably transfer a plate-like body even when the uppermost plate-like body is located beyond a regular height.

[0007]

SUMMARY OF THE INVENTION The present invention is directed to a lifter for raising a plurality of stacked plates by the height of each plate, and a top plate via a plurality of engaging members. The engagement member is provided with a main body that can swing only in the direction of transport of the plate-like body, and is provided slidably in the up-down direction with respect to the main body. And a claw body that is continuous with the upper edge of the engagement surface and that has an upwardly sloped front surface formed in the direction of transport of the plate-like body. When pushing out the uppermost plate-like body by operating the means to advance the engaging member,
The claw body is raised by advancing while the inclined surface thereof contacts the rear upper edge of the plate-like body, and is guided so that the engagement surface comes into contact with the rear side surface of the plate-like body. is there.

[0008]

When the stacked plate-like bodies are stacked on the lifter, the lifter rises by the height of one plate-like body. When the lifter rises, the transfer means operates to advance the engaging member toward the plate-like body, so that the engaging member comes into contact with and pushes out the uppermost plate-like body.

At this time, even if the uppermost plate-like body exceeds the regular height, the claw body of the engaging member is advanced while the inclined surface thereof contacts the rear upper edge of the plate-like body. It rises by the amount that it has advanced along the slope. As a result, the engaging surface of the claw body is guided so as to abut on the rear surface of the plate-shaped body. This ensures that only the body is transferred.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows the overall configuration of a transfer device 1. The transfer device 1 is a lifter 2 that raises a frame F, which is a plate-like body having a predetermined number of sheets stacked, by the height of one sheet. And the transfer means 3 and the engaging member 4 for transferring the uppermost frame frame of the frame frames F stacked on the lifter 2 to a predetermined position, that is, a roller conveyor 21 described later.

The lifter 2 is a conventional well-known type that raises and lowers the table 6 via a pantograph mechanism 5 and an air cylinder (not shown). Of the frame frames F stacked on the table 6, only the uppermost frame frame will be described later. Roller conveyor 21 via transfer means 3 and engaging member 4
After being extruded and transported, the table 6 is
, And stand by so that the next frame can be transported as the uppermost frame. Then, when the set number of the frame frames are sequentially transferred and the transfer of the lowermost frame frame is completed, the table 6 is lowered, and a new frame frame F having the set number of stacked frames is allowed to be carried in.

The transfer means 3 includes a drive shaft 8 rotatably supported by a fixed frame 7, a drive sprocket 9 fixed to the drive shaft 8, and a driven shaft rotatably supported by the fixed frame 7. 8A, a driven sprocket 9A fixed to the driving shaft 8A, and a chain 10 wound between the driving sprocket 9 and the driven sprocket 9A. The driving sprocket 9, the driven sprocket 9A and the chain 10 are detailed. Although not shown, a plurality of rows are arranged at predetermined intervals in the left-right direction (the direction orthogonal to the paper surface of FIG. 1). Further, a frame 71 having a U-shaped cross section is connected to the fixed frame 7 corresponding to the chains 10 arranged in a plurality of rows, and the frame 71 is provided with a guide 71a to support the chain 10. I have. Further, the frame 72 connected to the fixed frame 7
Is provided with a guide 72a.
The chain 10 is opposed to the above-described guide 71a.
I support.

Therefore, the chain 10 can be circulated around the sprockets 9 and 9A by rotating the driving sprocket 9 via a driving device such as an electric motor (not shown). At this time, the rollers constituting the chain 10 are sandwiched from above and below by the guides 71a and 72a (see FIG. 3).
0 moves the regular height position in the front-back direction (the left-right direction in FIG. 1).

By the way, the adjacent chains 10, 10
A connecting member 11 is provided between the connecting members 11, and one or a plurality of engaging members 4 are pivotally supported on each of the connecting members 11 in a swingable manner. The engaging member 4 is composed of a main body 13 supported by a mounting bracket 12 provided on the connecting member 11 and a claw body 14 slidable in the vertical direction with respect to the main body 13.

The main body 13 of the engaging member 4 comprises a head having a pin hole formed therein and a body having a vertically extending guide hole 13a (see FIG. 3) formed therein.
The body 13 is pivotally supported by the mounting bracket 12 by swinging the pin 15 through the head of the body 13 on the head 2. The lower front corner of the mounting bracket 12 is cut off to form a notch 12a.
As a result, the main body 13 is moved only forward (toward the transfer side of the frame F) within a range from the position where the main body 13 is suspended from the mounting bracket 12 to the time when the upper surface of the body engages the notch 12a of the mounting bracket 12. Swing is allowed (the state shown by a dashed line in FIG. 2).

The claw body 14 has a rod 16 which can be inserted into the guide hole 13a formed in the main body 13 connected to the upper surface thereof. An engaging surface 14a, and an inclined surface 1 having an upward slope from the upper edge of the engaging surface 14a toward the direction of transport of the plate-like body F.
4b are formed. As will be described later, the engagement surface 14a of the claw body 14 contacts the rear side surface of the frame F, and the inclined surface 14b contacts the rear upper edge of the frame F.

The height of the engaging surface 14a formed on the front surface of the claw body 14 is set slightly smaller than the height of the frame frame F, and the height of the inclined surface 14b is set to the set number of frame frames F. Are determined based on the maximum error assumed when stacking.

On both left and right sides of the main body 12, a support piece 17 having an elongated hole 17a extending vertically is vertically provided so as to sandwich the claw body 14.
A pin 18 that penetrates through the claw body 14 and protrudes from the side surface thereof is fitted into a. As a result, the claw body 14 is normally lowered by its own weight until the pin 18 engages with the lower end of the long hole 17a formed in the support piece 17, and the claw body 14 has a long hole against its own weight. It can move up and down within the range of 17a. Then, the pin 18 is inserted into the long hole 17a of the support piece 17.
The lower surface of the claw body 14 is positioned slightly higher than the bottom surface of the uppermost frame frame located at the regular height. Therefore, when a set number of the plate-like bodies F are stacked, a change in height due to welding deformation or the like always appears as a height higher than this.

In FIG. 1, reference numeral 21 denotes a frame frame F
, A roller conveyor 22 for transporting the gypsum board B, and a guide plate 23 disposed between the roller conveyor 21 and the lifter 2 to guide the frame F. Then, the gypsum board B is carried in from the left and right directions by the roller conveyor 22, and the frame F is guided by the transfer means 3 and the engaging member 4 to the guide plate 2.

Next, the operation of this embodiment will be described. At the start of the operation, the engaging member 4 is at the rearmost position (the position indicated by the one-dot chain line in FIG. 2), and the lifter 2 is lowered. Here, when the set number of stacked frame frames F are carried into the table 6, the transfer means 3 is operated, and the transfer means 3 is operated.
The engaging member 4 connected to the chain 10 is moved forward. At this time, the chain 10 moves up and down the guide 71
As a result, the engaging member 4 also moves at a constant height following the normal height, and the engaging surface 14a of the claw body 14 constituting the engaging member 4 is moved to the uppermost position. In contact with the rear side surface of the _first frame frame F1 located at.
Further, when the operation of the transfer means 3 is continued, the engaging member 4 cannot swing backward, so that the frame F ₁
The engaging surface 14 a of the claw body 14 abuts on the rear side surface of the frame member ₁ , extrudes the frame F _1, and transfers the frame frame F ₁ to the roller conveyor 21 via the guide plate 23.

Thereafter, the frame frames F are similarly transferred, and when the transfer of the set number of frame frames F is completed, the lifter 2 is operated to lower the table 6, and the new set number of frame frames F are stacked. You just need to bring it in.

By the way, when the frame F is carried in,
If the frame frame height of F ₁ the uppermost exceeds the height of the regular engagement member 4, the frame frame F ₁ inclined surface 14b of the uppermost of the pawl member 14 to move the height of the normal (The two-dot chain line in FIG. 2). When the inclined surface 14b of the claw 14 is advanced while in contact with the upper rear edge of the frame frame F _1, the pawl 14 is the inclined surface 14b minute pushed up was advanced along the against its own weight, engaging guiding the mating surface 14a to abut on the rear side surface of the frame frame F _1. Therefore, if continued advancement of the engagement member 4 by the transfer means 3, it can be pushed only framework F ₁ the uppermost. In this case, if extruded frame frame F ₁ of the uppermost stage to the guide plate 23 away next frame frame _2, the claw 14 drops by its own weight.

In this embodiment, the claw body 14 descends by its own weight with respect to the main body 13, but a compression force can be applied via a spring.
