Abstract

A device for weighing commodities, for automatically calculating the price of the weighed commodity on the basis of a tariff, and for printing out the end price and weight on a ticket to accompany the commodity. The device is equipped for a quick and foolproof adaption to a change of commodity, and by a special combination of memories and code selector switches provides a versatile instrument for rounding up calculated values, to conversion to different currency systems, for summing and storing selected signals, and for modifying the weight/price tariff.

Claims

1. A weighing and price calculating device comprising a weigher, a calculator connected to said weigher and adapted to receive signals therefrom corresponding to the weights of goods passed to said weigher, a data distributor connected to said calculator, and a printer coupled to said data distributor for printing out signalled weights and prices calculated therefrom on to labels to accompany the weighed goods; the improvement which includes a first memory connected to the weigher, for receiving a series of digits representing the weight of the goods on the weigher; a second memory in which is stored a series of digits representing the price per unit weight of the material being weighed; a sensing device positioned adjacent to the weigher and adapted to generate an output electrical pulse when the goods are moved away from the weigher; a calculator coupled to said first and second memories for multiplying the weight of the goods with the price per unit weight; a control circuit connected to said sensing device for actuation to start a multiplication sequence when said electrical pulse is received; said calculator adapted to provide a price for the goods in digit form and to apply the price to an output circuit; and a printer coupled to the calculator output circuit for printing the price of the goods on the label.

2. A weighing and price calculating device comprising a weigher, a calculator connected to said weigher and adapted to receive signals therefrom corresponding to the weights of goods passed to said weigher, a data distributor connected to said calculator, and a printer coupled to said data distributor for printing out signalled weights and prices calculated therefrom on to labels to accompany the weighed goods; the improvement which includes a first memory connected to the weigher, for receiving a series of digits representing the weight of the goods on the weigher; a second memory in which is stored a series of digits representing the price per unit weight of the material being weighed; a third memory in which is stored a series of symbols indicating the address of a purchaser; a sensing device positioned adjacent to the weigher and adapted to generate an output electrical pulse when the goods are moved away from the weigher; a calculator coupled to said first and second memories for multiplying the weight of the goods with the price per unit weight; a control circuit connected to said sensing device for actuation to start a multiplication sequence when said electrical pulse is received; said calculator adapted to provide a price for the goods in digit form and to apply the price to an output circuit; and a printer coupled to the calculator output circuit for printing the price of the goods on a label.

3. A weighing and calculating device according to claim 1 whereby said third memory includes a series of punched data cards, said cards available for manual insertion into said printer for printing the address contained in the selected card on the goods.

4. A weighing and price calculating device according to claim 1 wherein said printer includes a slot for depositing printing plates, each printing plate carrying the name of a commodity.

5. A weighing and price calculating device according to claim 1 wherein the calculator includes two multiplying circuits which operate independently of one another, each of said circuits coupled to a comparator circuit for checking the products of the multiplying circuits.
