Abstract

The invention relates to a system for the prevention of theft in salesrooms. The weight of a customer is measured when he enters and when he leaves the salesrooms, and the two measurements are compared. According to the invention, a zone for placing the goods on a conveyor belt is separated spatially from a zone for paying for the goods. The zone for paying can be reached only after passing of an exit installation having a weighing device.

Claims

1. A method for the prevention of theft in salesrooms, including a weight check at the entrance and the exit of the salesroom, in which the weight of a customer measured at the entrance in the region of an entry installation (10) is recorded and compared to the weight measured at the exit in the region of an exit installation (22), and in which, when the customer leaves the salesrooms, payment takes place in the region of a check-out installation (20), and a conveyance of goods in a downstream direction takes place in the region of a goods transport device assigned to the check-out installation (20), said method comprising, in order to leave the salesrooms, the steps of:

first placing the goods on the goods transport device in a depositing zone (34);

next, measuring the weight of the customer in the region of the exit installation (22); and

, thereafter, paying for the goods only in a paying zone (35) which is separated from the depositing zone (34) and located downstream with respect to the goods transport device.

2. The method as claimed in claim 1, further comprising the step of releasing a barrier which prevents a customer'"'"'s entry from the exit installation (22) to the paying zone only if the determined difference of the weights measured at the entrance installation and the exit installation is below a defined maximum value.

3. A system for the prevention of theft by means of an entrance and exit control in salesrooms, comprising:

a) an entry installation (10) comprising a first weighing device (11) for weighing customers entering the salesrooms, a first gate (12) which has to be passed after weighing and a ticket dispenser (13);

b) an exit installation (22) comprising a second weighing device (23) for weighing customers exiting the salesrooms, a second gate (30) which has to be passed after weighing, and a ticket controlling device (25) for comparing the weights measured by said first and second weighing devices (11,

     23) and for controlling said second gate (30);

c) a check-out installation (20) comprising a goods transport device (32), and a goods chute (33), adjoining the goods transport device (33), for the delivery of the goods to the customer, or for the receipt of the goods by the customer;

d) a depositing zone (34) for placing goods on the goods transport device; and

e) a paying zone (35), adjacent to the depositing zone (34), for paying for the goods;

f) wherein said check-out installation is disposed on one side of said goods transport device, and said depositing zone (34) and said paying zone (35) are disposed on an opposite side of said goods transport device;

g) wherein said depositing zone (34) and said paying zone (35) are separated from one another by a barrier (36) which cannot be passed by the customers; and

h) wherein said exit installation (22) is disposed at a distance from the goods transport device (32), such that said depositing and paying zones (34,

     35), together with said barrier (36), are located between said exit installation (22) and said goods transport device (33).

4. The system as claimed in claim 3, wherein said barrier (36) is an upright wall which screens off the goods transport device (32).

5. The system as claimed in claim 3, wherein the barrier (36) has a passage for a shopping cart.

6. The system as claimed in claim 5, wherein a separate signal device (37, 31) is disposed in front of the depositing zone (34) and/or the exit installation (22).

7. The system as claimed in claim 3, wherein the exit installation (22) and/or the entry installation (10) has an inner region which can be entered, and at least one vertical wall (14, 15;

28,

     29) for screening off the inner region toward the outside, and wherein the wall is mechanically coupled to the respective first or second weighing device (11,

     23) in the form of a weighing platform (18,

     24) filling out a floor area of an interior space.

8. The system as claimed in claim 7, wherein the weighing process on the weighing platform (18, 24) is controllable in response to the position of the respective first and second gate (12, 30), such that the weighing process is conductable in a specific position of said respective gate.

9. The system as claimed in claim 3, comprising two check-out installations, each having a goods transport device, a depositing device and a paying zone, and wherein these check-out installations are arranged relative to one another in an approximately mirror-inverted manner, with a common exit installation being located between the two check-out installations.

10. A system for the prevention of theft by means of and entrance an exit control in salesrooms, comprising:

a) an entry installation (10) comprising a first weighing device (11) for weighing customers entering the salesrooms, a first gate (12) which has to be passed after weighing and a ticket dispenser (13);

b) an exit installation (22) comprising a second weighing device (23) for weighing customers exiting the salesrooms, a second gate (30) which has to be passed after weighing, and a ticket controlling device (25) for comparing the weights measured by said first and second weighing devices (11,

     23) and for controlling said second gate (30);

c) a check-out installation (20) comprising a goods transport device (32), and a goods chute (33), adjoining the goods transport device (33), for the delivery of the goods to the customer, or for the receipt of the goods by the customer;

d) a depositing zone (34) for placing goods on the goods transport device; and

e) a paying zone (35), adjacent to the depositing zone (34), for paying for the goods;

f) wherein said check-out installation is disposed on one side of said goods transport device, and said depositing zone (34) and said paying zone (35) are disposed on an opposite side of said goods transport device; and

g) wherein said exit installation (22) and said entry installation (10) are located on opposite sides on said check-out installation (20).
