Abstract

The staple locating device positions the staples driven into the side of a filled, corrugated board outer card container. The staples, thus driven, serve as a destination code for subsequent electrical sensing and sorting.

Staple Locating Device

The staple locating device positions the staples driven into the side of a filled, corrugated board outer card container. The staples, thus driven, serve as a destination code for subsequent electrical sensing and sorting.

Staples are driven into the side of the container so that they are accurately located relative to two adjacent edges. Staples are inserted in any one of four positions on the X-axis and in any one of sixteen positions on the Y-axis.

Cardboard containers 1 are moved intermittently by air cylinder 2 and the cam shaped puller hook 3 on wheels 4 along guide 5. Container 6 will receive its staple on the next forward stroke of the air cylinder 2. Cam 7 attached to the puller hook assembly closes the four switches 8, one at a time, on the forward stroke of air cylinder 2. The distance between the switches 8 is equal to the distance between the staple columns on the containers. Any one staple column can be selected by closing the corresponding switch 9 through a control unit (not shown) so that when cam 7 on its forward stroke closes the corresponding switch 8 the solenoid valve 10 is energized, compressed air is admitted to the stapler gun 11 and a staple is driven into its proper column.

The stapler gun 11 has been previously positioned in one of sixteen locations at a right angle to the motion of the containers by a chain of binary air cylinders
12. The strokes of the air cylinders 12 are 1, 2, 4 and 8 units which by proper co...
