A conveying apparatus for transporting and for measuring an object includes a sensor having a light transmitter arranged at a conveyor belt and transmits first light beams in the direction of the conveyor belt. The sensor also has a light receiver that is arranged at the conveyor belt and that receives second light beams. The sensor further has an evaluation device for determining a dimension of the object by evaluating the received second light beams. The conveyor belt is an endless conveyor belt that is driven by at least one drive unit and that moves in a main conveying direction. At least one gap is provided in the endless conveyor belt free of interruption, through which gap the first light beams pass, and the first light beams form a scan plane in the at least one gap transversely to the main conveying direction of the conveyor belt.

Conveying apparatus

The invention relates to an RFID reading tunnel for identifying objects by means of RFID having a screen for electromagnetic radiation which forms the tunnel and has side walls and a cover part, a cover device or conveying device for the object in or through the tunnel and at least one RFID reader having at least one RFID antenna. To provide an improved RFID reading tunnel which is less expensive and can be installed more easily, it is proposed that the screen is formed by modules which can be variably and releasably connected to one another and that the modules are selected from a kit of predefined modules.

RFID reading tunnel for identifying objects by means of RFID

An optoelectronic sensor has a light source ( ) for the transmission of a scanning beam ( ), a light deflection unit ( ), which is formed for the periodic deflection of the scanning beam ( ) within an angular transmitting range ( ), a receiving device for detection light reflected from an object to be sensed and/or back-scattered light, and a deflector ( ) which has a light entry surface ( ) arranged at least regionally within the angular transmission range ( ). The light deflector is formed for the deflection of light incident through the light entry surface ( ) onto a photo-detector ( ). The photo-detector ( ) can be coupled to a synchronization circuit to produce a synchronization pulse for the determination of the start of a sensing period.

An apparatus is described for the adjustment of the focal position of an opto-electronic apparatus including a transmitter element which transmits light and a lens for the focusing of the light transmitted by the transmitter element. The apparatus includes a pivotal lever for receiving the transmitter element or the lens, which is pivotable via a positioning element about a pivot joint for the adjustment of the spacing between the transmitter element and the lens and thus for the adjustment of the focal position. The pivotal lever is formed as a two-armed pivotal lever, with the one arm of the pivotal lever being formed to receive the lens or the transmitter element, and with the positioning element acting on a section of the other arm of the pivotal lever lying on the other side of the pivot joint. Furthermore, a variant is described in which the positioning element extends along the longitudinal extent of the pivotal lever, as well as an opto-electronic apparatus with such an adjustment device.
