[Action]

 In the center, there is a lifting section that stacks glass plates and spacers on the Pareto, on one side of both sides is a conveyor that moves the glass plates, and on the other side is a storage section that places the spacers on top of it. A pair of suction plates installed on both sides of the sliding part that moves along the rails are different in adsorption and desorption operation during the movement of the sliding part, that is, one of the suction plates sucks the glass plate on the conveyor. The other suction tool holds the other glass plate by desorbing the spacer during suction, and then drops the spacer onto the glass plate loaded on the lifting part, and then the glass plate that has been sucked and held after the sliding part moves laterally. The suction plate on one side adsorbs the spacer of the storage part, and the glass plates and spacers are alternately laminated on the pallet by a pair of suction plates that move left and right along the rails. Glass plates laminated by moving moves to the next step.

Lifting portions 8 that support the pallets 6 by rolls 7 and can move up and down and travel on the pallets are provided at positions where the conveyors 3 are sandwiched, and the lifting portions are sandwiched, that is, the stopper 4 and the lifting portions. A large number of spacers 10 are accommodated in an overlapping manner and a vertically movable accommodating portion 11 is continuously provided at a position adjacent to the extension portion 8 extending in a horizontal line, and a pushing pusher 12 is provided behind the lifting portion 8. Is provided, and a loading portion 13 for the pallet 6 that pushes the pallet 6 forward is provided, and a roll conveyor 14 that transfers the pallet 6 forward is disposed in front of the lifting.

A beam portion 15 supported by a column (not shown) is installed in a gate shape above the transport conveyors 3 and the lifting portion 8 and the accommodating portion 11 which are arranged side by side, and a rack 16 is provided on the upper surface of the beam portion. On the side surface, a rail 17 with a groove is provided to mount a sliding body 18. A servomotor 20 with a pulse transmitter is seated on the sliding body, and a pinion 21 provided at the shaft end of the motor is mounted on the rack. 16 engages with the motor 16 to convert the rotating motion of the motor 20 into a linear motion so that the sliding body 18 can be moved laterally along the rail 17.

Guide rods 22 are fixed to the left and right of the traversing sliding body, and a pair of slidable suspension portions 23 are provided on the guide rods, and a cylinder 24 is fixed to each suspension portion vertically. At the tip of the rod, suction plates 26 and 26 'are provided which are connected to a suction source (not shown) and communicate with the notched hose 25. The suction plates 26 and 26' are also provided between the suspension part 23 and the sliding body 18 in parallel with the guide rod 22. A cylinder 27 is provided to adjust the distance between the suction plates 26 and 26 ', and two kinds of distance are provided by the on / off expansion and contraction of the cylinder rod.

The operation of the present invention will be described below. In a state where a large number of spacers 10 are placed in the accommodating portion 11 and the pallet 6 is pushed out by the pusher 12 onto the roll 7 of the lifting portion 8 from the carry-in portion 13, the glass plate 1 which is being moved forward by the conveying conveyor 3. When a sensor (not shown) catches the movement of the glass plate in advance, and the signal comes in contact with the stopper 4 ', which stands on the belt 2 and stands by, it stops by the sensor (not shown). Also stops driving. Then, the glass plate 1 is moved forward by the pusher 5 to the left side, and the stopper 4 protruding above the belt 2 is brought into contact with the edge of the glass plate 1 to position the glass plate 1 in the front-rear direction and the left-right direction. Then, the stoppers 4 and 4 ′ protruding from the belt 2 descend from the upper surface of the belt.

The sliding body 18 mounted on the rail 17 and waiting is traversed forward to the right by the rack 16 with which the pinion 21 is rotated and meshed with the operation of the motor 20 together with the descending signals of the stoppers 4 and 4 ′. When the position of the suspending portion 23 provided on the right side of the sliding body 18 reaches the positioned glass plate 1, the suction plate 26 'which is traversed and descends by the forward movement of the driven cylinder 24 is the positioned glass plate. When it comes into contact with No. 1, the suction plate 26 'sucks and holds the glass plate 1 by the suction operation from the suction source (not shown) on the hose 25, and one suction plate 26 also drops onto the pallet 6 of the lifting section 8.

The glass plate 1 supported by the suction plate 26 ′ is lifted by the backward movement of the cylinder 24, and then the sliding body 18 is traversed to the left by the reversal of the motor 20, and the suction plate 26 ′ of the lifting portion 8 is moved. When the glass plate 1 reaches the upper part and is lowered again by the operation of the cylinder 24 to release the suction of the suction plate 26 ', the glass plate 1 is set on the pallet 6 placed on the lifting section 8, but one suction plate 26 is At the same time, when the spacer 10 is moved to the housing portion 11 and lowered and sucked, the uppermost one of the spacers 10 placed in an overlapping state is sucked into the housing portion.

The suction plates 26, 26 ′ traverse to the right side again due to the backward movement of the cylinder 24 and the rotation of the motor 20, and the suction plates 26, 26 ′ stop at a predetermined position by the pulsating signal of the motor 20 and the suction plate is moved by the forward movement of the cylinder 24. The spacer 10 adsorbed and supported by 26 abuts against the glass plate 1 on the pallet 6 of the lifting portion 8, and the spacer 10 separated from the adsorbing plate 26 by the adsorption release is placed on the glass plate 1. One of the suction plates 26 'moves onto the transporting conveyor 3 and descends and is newly moved by suctioning on the transporting conveyor to suck and support the glass plate 1 positioned by the pusher 5 and the stoppers 4 and 4', The sliding member 18 is repeatedly traversed in the same manner, but during the traversing, the lift portion 8 is lowered by the laminated thickness in accordance with the lamination of the glass plate 1 and the spacer 10 by the pulse transmission from the motor 20, and one of the accommodating portions is received. Since 11 rises by the thickness corresponding to the reduction of the spacer 10, the glass plate 1 on the conveyor 3 and the spacer 10 or the glass plate 1 on the lifting section 8 and the uppermost step on the placing section 11 The level with the spacer is always constant, and the vertical reciprocating movement of the cylinder 24 is always constant.

When the glass plate 1 and the spacer 10 are alternately placed on the pallet 6 supported by the lifting device 8 and a certain amount is measured by a counter (not shown) and the pusher 12 is operated, the glass plate 1 and the spacer 10 are moved from the carry-in section 13 by the operation. The new pallet 6 is pushed into the lifting section 8, and the pallet 6 placed on the roll 7 of the lifting section 8 is pushed out onto the roll conveyor 14 in a random manner.

When handling glass plates 1 having different sizes, since the pitch between the suction plates 26, 26 ′ is different, the cylinder 27 is operated and the rod of the cylinder is suspended at a predetermined position by a stopper (not shown). If the suction is stopped, the length between the suction plates 26 and 26 'may be corrected, and the spacer 10 matching the size of the glass plate 1 may be placed on the accommodating portion 11.
