Work loading method for automatic palletizer, work loading method, work loading apparatus and attachment replacing method thereof
First Claim
1. A work loading method of an automatic palletizer for loading a work, which is carried out of a press, into a pallet by a robot, comprising the steps of:
- positioning the works with two centering devices at an upstream side and a downstream side in a work transfer direction every other press shot; and
making pairs of two robots each, which are located diagonally from each other, out of four of said robots in total, two of which are on a left and two of which are on a right to oppose each other in the work transfer direction with two of said centering devices between them, said two robots of each pair holding the works, which are on two of said centering devices, and performing a loading operation of the works into said pallets, each pair alternately holding the works and performing the loading operation each time two of said centering devices position the works.

10. An attachment replacing method of a work loading apparatus for positioning a work, which is carried out of a press, with a centering device and loading the positioned work into a pallet with a robot, said attachment replacing method being of replacing at least either one of an attachment for said centering device or an attachment for said robot according to the work, comprising:
-
a first step of housing at least either one of a used attachment for the centering device or a used attachment for the robot into at lease any one of said pallets loaded on a pallet feeder which makes said pallets movable between a work loading position within a movable range of said robot and a predetermined position outside the movable range; and
a second step of attaching at least either one of the attachment for the centering device to be used next or the attachment for the robot to be used next, which is placed on the same pallet as or a different pallet from the pallet housing at least either one of said used attachment for the centering device or said used attachment for the robot, to the centering device itself, or the robot.

11. A work loading apparatus for positioning a work, which is carried out of a press, with a centering device, and loading the positioned work into a pallet with a robot, comprising:
-
a pallet feeder which makes said pallets movable between a work loading position within a movable range of said robot and a predetermined position outside the movable range;
wherein any pallet out of said pallets loaded on said pallet feeder houses at least either one of a used attachment for the centering device or a used attachment for the robot; and
wherein the pallet, which is the same as or a different from the pallet housing at least either one of said used attachment for the centering device or said used attachment for said robot, houses at least either one of the attachment for the centering device to be used next or the attachment for the robot to be used next. - View Dependent Claims (12)
