Abstract
A system for detecting labels arranged on a support and spaced apart from one another by a spacing, the system including a transmitter part including a transmitter arranged to transmit a beam of ultrasonic waves towards the support which carries the labels, a receiver part, separated from the transmitter part, such that the support carrying the labels can pass along a plane located between the transmitter part and the receiver part, the transmitter part or the receiver part being arranged so that the beam of ultrasonic waves transmitted by the transmitter covers, on the support carrying the labels, a total surface area in which the surface area occupied by the spacing between two labels is greater than the surface area occupied by the labels.
Claims8
A system for detecting labels arranged on a support and spaced apart from one another by a spacing, said system comprising:
- a transmitter part comprising a transmitter arranged to transmit a beam of ultrasonic waves towards the support which carries said labels;
- and
- a receiver part, separated from the transmitter part, such that the support carrying the labels can pass along a plane located between the transmitter part and the receiver part, in a passage direction, and in a passage plane, the receiver part comprising a receiver arranged to generate an output signal on the basis of a beam of ultrasonic waves attenuated by the support and/or the labels,
- wherein the transmitter part or the receiver part is arranged so that the beam of ultrasonic waves transmitted by the transmitter covers, on the support carrying the labels, a total surface area, and within this total surface area, the surface area occupied by the spacing between two successive labels is greater than the surface area occupied by the labels, and
- wherein an angled reflection device is arranged in the receiver part, the angled reflection device including a first deflector arranged to deflect the attenuated beam of ultrasonic waves towards a second deflector, the second deflector being arranged to deflect the attenuated beam of ultrasonic waves towards the receiver.
A system for detecting labels arranged on a support and spaced apart from one another by a spacing, said system comprising:
- a transmitter part comprising a transmitter arranged to transmit a beam of ultrasonic waves towards the support which carries said labels;
- and
- a receiver part, separated from the transmitter part, such that the support carrying the labels can pass along a plane located between the transmitter part and the receiver part, in a passage direction, and in a passage plane, the receiver part comprising a receiver arranged to generate an output signal on the basis of a beam of ultrasonic waves attenuated by the support and/or the labels, wherein
- an angled reflection device is arranged in the transmitter part, the angled reflection device including a first deflector and a second deflector, the first deflector being arranged to deflect the beam of ultrasonic waves transmitted by the transmitter towards the second deflector along a deflection direction at an angle of between 0° and 90° to the passage direction, said second deflector being arranged to deflect the transmitted beam of ultrasonic waves towards the receiver, and
- the transmitter part or the receiver part is arranged so that the beam of ultrasonic waves transmitted by the transmitter covers, on the support carrying the labels, a total surface area, and within this total surface area, the surface area occupied by the spacing between two successive labels is greater than the surface area occupied by the labels.
