A device for detecting moving containers

摘要

Disclosed is a device (1) for detecting containers moving along a conveyor and a conveyor for containers. The disclosure notes that existing devices for detecting containers comprise a plurality of sensors mounted on a plate of a carousel. The increased number of sensors increases the overall dimensions of the carousel. Furthermore, sensors are connected to the carousel using brackets which make it difficult to access the internal components of the carousel for maintenance. The device (1) for detecting containers comprises a support structure; at least one detection sensor (15); synchronising means and motor-driven means (40). The at least one detection sensor (15) is connected to the support structure and is operatively associated with a container moving along the conveyor so as to detect a characteristic of the container. The synchronising means synchronises the sensor (15) with the container. The synchronising means are active on the sensor (15) to move it so that the sensor (15) follows the container along at least one part of a feed path from an initial position to a final position. The synchronising means comprise a guide fixed to the support structure and a mobile structure (18) slidably mounted on the guide. The sensor (15) is fixed to the mobile structure (18) for moving at least from the initial position to the final position. The mobile structure (18) comprises a closed-loop transmission unit to which at least one sensor (15) is connected. The motor-driven means (40) moves the mobile structure (18) with respect to the support structure.
