本发明涉及一种标签检测系统设置在支撑（2），并通过距离（E）间隔开，所述系统包括： - 发送器部分，其包括一个发射器（30），被布置成发射束（ F1）朝向载体的超声波的支撑所述标签， - 接收部分从发送器部分分开，使得所述载体（1）支撑所述标签可以通过发送器部分和接收器部分，之间的平面滚动 - 发射部分或接收部分被布置为使得由发射器发射的超声波束在支撑标签（2）的支撑件上覆盖总面积（S1），在该总面积中， 两个标签比标签占用的面积更重要。

The invention relates to a label detection system (2) arranged on a support and spaced apart by a distance (e), said system comprising:
- a transmitter part comprising a transmitter (30) arranged for emitting a beam (F1) of ultrasonic waves towards the carrier supporting said labels,
- a receiving section separated from the emitter portion so that the carrier (1) supporting the labels can scroll through a plane between the transmitter part and the receiver part,
- the transmitter or the receiver portion being arranged so that the ultrasonic wave beam transmitted by the transmitter covers on the carrier carrying the labels (2), a surface (S1) wherein the total surface occupied by the spacing between two labels is larger than the area occupied by the labels.
