Abstract

A weighing cell for weighing moving goods comprises a plug connection on the load receptor for the mechanical and/or electrical connection of the weighing cell to the conveyor system moving the goods.

Claims

1. A weighing cell (1) for determining the weight of transported goods,

a) wherein the goods are transported by a conveyor system, and

b) wherein the conveyor system is placed on the load receptor (2) of the weighing cell (1) in order to transmit the weight to be measured,

characterized by the fact that

c) the load receptor (2) of the weighing cell (1) features a first part (3) of a plug connection for producing an electrical and/or mechanical connection with the conveyor system, wherein this first part of the plug connection can be mated with a complementary second part of the plug connection arranged on the conveyor system.

2. The weighing cell according to claim 1, characterized by the fact that the conveyor system can be completely connected or disconnected mechanically and/or electrically by respectively placing the conveyor system on the load receptor or removing the conveyor system from the load receptor.

3. The weighing cell according to one of the preceding claims, characterized by the fact that all electrical connections required for the operation of the conveyor system are produced with the aid of the plug connection by placing the conveyor system on the load receptor.

4. The weighing cell according to one of the preceding claims, characterized by the fact that the plug connection is protected against twisting or polarity reversal.

5. The weighing cell according to one of the preceding claims, characterized by the fact that the plug connection features centering means (4) for aligning the two parts of the plug connection in a precisely fitting fashion during the mating process.

6. The weighing cell according to one of the preceding claims, characterized by the fact that the plug connection is realized as explosion-proof and/or IP-protected and/or metallically encapsulated in order to improve the electromagnetic compatibility.

7. The weighing cell according to one of the preceding claims, characterized by the fact that the weighing cell features a detachable quick-action clamping device for securing the attached and connected conveyor system relative to the weighing cell.

8. The weighing cell according to the preceding claim, characterized by the fact that the quick-action clamping device can be actuated without a tool.
