Abstract
Abstract In order to speed up the check-out of customers at a discount store operation, and in order to eliminate one person at the station who has to package the groceries or merchandise, the within invention has been developed. There is a tray with a cover which is of the overall dimensions of the typical grocery bag but slightly smaller. There is a lid cover on top of the tray. At the bottom of the tray is a movable tray to which a tongue is attached. At the end of the tray are a pair of doors. These doors are located away from the cash register area and toward the exit. When the cover is closed and the tray is filled with groceries a switch is actuated causing the doors to open and the tray and the tongue with the groceries to move through the doors. While the groceries are being placed in the tray, a bag is opened and is positioned horizontally to receive the groceries. As soon as the groceries have been inserted in the bag, the bag is now uprighted and the tongue acts as a shoehorn so that the groceries are gently deposited in the bag. The tongue and the tray are returned to the normal position and the bag filled with the groceries is conveyed in this instance to a rotary type conveyor which acts as a pick-up station from where the customer may collect the grocery bags. There is an electrical control circuit for synchronizing and operating the aforesaid functions. There is a special bag opening means whereby a blower assists the opening of the bags which are in a horizontal position in conjunction with suction cups which also assist the opening the bag and which suction cups are mounted on a movable arm which has to be displaced when the bags have been filled and are to be delivered to the conveyor. The electrical circuit is actuated by switches which are strategically placed at key locations along the path of the various pulleys and chains which operate the moving parts.
