Abstract

PURPOSE:To enhance the efficiency of a workpiece stacking device for stacking up workpieces on a transfer conveyor, by lifting up a workpiece above the conveyor and then by lowering the workpiece down to a holder provided with a movable receiving piece, which have been moved forward, to deliver the workpiece to the holder. CONSTITUTION:A workpiece W set on a transfer conveyor 2 is raised until the upper surface of a receiving bed 73 on an elevating bed 5 exceeds a receiving piece 3. Prior to this elevation the workpiece actuates a detector 104, and therefore an actuator 52 is extended to tilt a swing arm 59 in order to retract the receiving piece 3. When the workpiece W climbs up and therefore a detector 105 is actuated, the actuator 52 is retracted so that the receiving piece 3 is projected toward the transfer conveyor 2, and the workpiece W is lowered and set on the receiving piece 3. With the repetition of the above-mentioned steps, the workpieces W are stacked up one by one on the holder 4.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a work stacking device that can efficiently stack works on a conveyor in multiple stages.

(Background Art) It is often necessary to stack workpieces to be transported in multiple stages.

For example, in buildings using the dry method 1 method, architectural panels used as walls, floors, etc., in which face materials are adhered to frames with adhesives, are cured under pressure after adhesion until they harden. Ru. As a device for such curing, the present applicant has disclosed in the specification and drawings of Japanese Patent Application No. 58-226103 that panels P stacked on a trolley C are placed on top of the upper surface of the panel P, as schematically shown in FIG. We have proposed a panel conveyance device in which the rack is compressed between it and the plate U by a tensioning device T such as a turnbuckle, and is cured during the movement.

As shown in FIG.
Multiple curing lines L that curing the panel P while conveying the
1, L2, and L3 are juxtaposed between a carry-in line L4 and a carry-out line L5, each of which has a traverse table S1 and S2, respectively, and a loading line L6 and a dismissal line L7 are provided on the outside thereof. Further, a return conveyor CL is installed between the carry-in and carry-out lines L4 and L5, which is configured to return the cart C at the lower level and the upper receiving plate U at the upper level. Note that at the loading line L6, the panels P are stacked on the cart C that has been moved to the loading line L6.

Also, on the carry-in line L4, the upper receiving plate U on the return conveyor CL
After supplying and attaching tensioning tools T such as turnbuckles from the turnbuckle return line LIO, the curing lines L1, L2, and L3 are selected and carried in. Also, the panel P is cured during movement on the curing lines L1, L2, and L3,
It also operates to remove the tensioning device T such as a turnbuckle and the upper receiving plate 1 on the carry-out line L5, and to take out the panel P on the removal line L7.

For example, in such a panel transport device A, since the carts C are transported on the three curing lines L1 to L3, the number of carts C transported on the return conveyor CL increases, and therefore, the workpieces W on the cart C are stacked. It was necessary to raise it.
