The frame 2 on both sides is moved in both directions via a screw feed mechanism 6 by rotating a handle 5, respectively.

Conveyors 11 are disposed inside the frames 2 on both sides. This conveyor 11 is
It consists of a pair of conveyor bodies 12 attached to the inner parts of the frames 2 on both sides, and each of the pair of conveyor bodies 12 on both sides is constituted by a driven belt conveyor, and the endless belt of the conveyor bodies 12 on both sides 13 to support and convey a plate-shaped object W such as a synthetic resin foam used as a heat insulating material or a tatami core, etc., with both ends overhanging the outside of the conveyor body 12 on both sides. It's getting old.

A front stopper 15 is provided so as to be movable forward and backward relative to the conveyance path of the conveyor 11. This front stopper 15 is connected to the conveyor 11.
It consists of a pair of vertically long plates 16 that are located outside the conveyor body 12 on both sides of the frame 2 and are pivoted on the respective front ends of the frame 2 (downstream side in the conveying direction of the conveyor 11). By driving the air cylinders 17 provided on the upper part of each frame 2, the plates 16 move forward and backward with respect to the conveyance path of the conveyor 11 and above the conveyance path, and in the advanced state shown by the solid line, the conveyors on both sides A plate-like object W overhanging the outside of the body 12
It is designed to come into contact with the front ends of both ends.

Moreover, the elevator frames 21 are located behind the front stopper 15 (on the upstream side in the conveyance direction of the conveyor 11), and are located outside the conveyor bodies 12 on both sides of the conveyor 11, and are mounted on the frames 2 on both sides. , is supported so as to be able to rise and fall freely via a plurality of rails 22 provided on the frame 2 and a plurality of rollers 23 provided on the elevating frame 21, and the elevating frames 21 on both sides are provided at the bottom of each frame 2. By rotating the motor 24, the chain lifting mechanism 25 is used to raise and lower the chain.

A plurality of support pieces 31 are provided on each of the elevator frames 21 on both sides at predetermined intervals in multiple stages in the vertical direction, and at predetermined intervals in multiple rows in the front and back direction, and move back and forth toward the inside. The supporting pieces 31 of each of the plurality of vertical stages, which are freely pivoted,
By driving the air cylinders 32 disposed above each, the conveyors 11 on both sides of the conveyor 11 are moved synchronously into and out of the respective elevator frames 21 via the interlocking rods 33, and in the advanced state shown by the solid line in the figure. It is designed to come out at a position relative to both sides of the plate-like object W overhanging the outside of the conveyor body 12.

Further, a side stopper 35 that is long in the vertical direction is fixed to the inner side of one of the elevator frames 21 on both sides, located between each row of the support pieces 31 in multiple stages in the vertical direction and in multiple rows in the longitudinal direction. A vertically long side pusher 36 is disposed on the other side of the elevator frame 21 on both sides, facing the plurality of side stoppers 35, and the plurality of side pushers 36 connect the upper and lower parts of the elevator frame 2 to each other.
A plurality of air cylinders 37 provided between the conveyor 11 move forward and backward with respect to the opposing side stoppers 35, and sandwich the conveyance path of the conveyor 11 and the plate-shaped object W above the conveyance path between the conveyor 11 and the side stoppers 35. It's becoming like that.

Then, when stacking the plate-like objects W, the plate-like objects W are sequentially transferred to the conveyor 11 in the illustrated state.
It is carried in between the frames 21 on both sides.

When the plate-like object W is carried in between the frames 2 on both sides, the plate-like object W is stopped by the plates 16 on both sides of the front stopper 15 that has advanced into the conveyance path of the conveyor 11, and then The lifting frame 21 is raised from the lowest position by one step of the plurality of support pieces 31 in the vertical direction, thereby lifting the plate-like object W with the uppermost support pieces 31 on both sides in the inwardly extending state. Scoop up from conveyor 11.

Subsequently, when the next plate-like object W is carried in between the frames 2 on both sides, the plate-like object W is transferred to the conveyor 1 in the same way.
After the front stopper 15, which has been extended into the transport path 1, is stopped by the plates 16 on both sides, the elevator frames 21 on both sides are further raised by one step of the plurality of support pieces 31 in the vertical direction. As a result, the plate-shaped object W is scooped up from the conveyor 11 by the support pieces 31 on the second stage from the top on both sides, which are in a state of advancing inward.

By repeating such an operation, the plate-like object W is moved onto the conveyor 11 by the support pieces 31 of each stage.
Scoop up the bottom support piece 31 from the plate-shaped object W.
is scooped up from the conveyor 11, the next plate-like object W is stopped by the front stopper 15, and the support pieces 31 of each stage are retracted to the outside. Supported plate W
are dropped onto the plate-like objects W on the conveyor 11 and stacked in multiple stages.

Finally, the plurality of side pushers 36 are advanced toward the opposing side stoppers 35,
The plate-like objects W stacked in multiple stages on the conveyor 11 are held between the side stoppers 35 to adjust the stacking condition, and then, after retracting the plurality of side pushers 36 outward, the front stoppers 15 The plates 16 on both sides are retracted outward, the stacked plate-like objects W are carried out from between the frames 2 on both sides by the conveyor 11, and then the front stopper 1
The plates 16 on both sides of the plate 5 are advanced to the conveyance path and wait for the next plate-like object W.

Note that the above explanation is based on the support pieces 31 of each upper and lower stage.
However, if the target is a plate-like object W whose thickness is thinner than the interval between the supporting pieces 31 of each upper and lower tier, the supporting pieces of the appropriate tier are used. If 31 is left retracted outward, stacking becomes possible.

Furthermore, by moving the frames 2 on both sides toward and away from each other using their respective handles 5, changes in the width of the plate-like object W can be accommodated.

〔Effect of the invention〕

As described above, according to the present invention, each time a plate-like object is carried onto the conveyor inside the frames on both sides, the elevating frame on both sides is raised by one step of the plurality of support pieces in the vertical direction. As a result, the multiple stages of support pieces on both sides extending inward support the plate-like object at each stage and rise one stage at a time, and when the multiple stages of support pieces support the plate-like object at each stage, The support pieces of multiple stages are retracted to the outside, thereby allowing the plate-like objects of each stage to be dropped onto the conveyor and stacked in multiple stages.
