Device for monitoring objects -

The invention relates to a device for monitoring Gugenn bands, those with parallel end walls lying close together by a moving conveyor element along a conveyor track be, at least along a part of the conveyor organ Objects are guided by management bodies.

Monitoring, for example counting objects by a light barrier, is easily possible if the objects do not lie against one another or if they are partly round in plan and are only in lenticular contact with one another. If, however, the objects are, for example, cuboid and touch one another with their forehead surfaces, monitoring, for example by means of a light barrier, cannot be carried out without further ado, since there is a between the individual objects. It is not possible for a ray of light to pass ^{through that affects nine f J hu tozelle.}

The aim of the invention is to create a simple, space-consuming device which, with gentle treatment of the objects enables such monitoring.

BAD OftlOJNAt

The device according to the invention is characterized in that that deflection means are provided in the area of the conveyor track, which act on the objects in the course of their under the influence of Conveyor organs acting movement along the conveyor tap and divert the same out of the original conveying direction determined by the guide elements in such a way that between them successive objects in the deflection zone wedge-shaped gap arises, and that further monitoring means are provided, which through the wedge-shaped gap-between the objects are influenced,

A (great) is expediently provided as a means of deflection, which for the purpose of Treat the conveyed objects as gently as possible ttin the peripheral speed corresponding to the conveying speed can be driven.

An exemplary embodiment of the subject matter of the invention is in Drawing shown schematically. Show it:

Fig. 1 is a side view of a device according to the invention for monitoring objects and

Fig. 2 is a plan view of this device. ⁽

On top of an endless conveyor belt 1 that goes around pulleys 3, 4 revolve, are quaderfürmiye objects 2 in the direction of the arrow promoted. The objects 2 lie with their end walls to each other. You are at the beginning of the conveyor belt 1 by guide walls 5, 6 dcjrart led them to one side over the Conveyor belt 1 protrude. In the middle area of the conveyor belt a deflecting roller 7 is arranged around a vertical axis rotates. The guide wall 5 opposite the roller 7 has in FIG near the roll two kinks 5a, 5b and then runs near the left Ranrifis dct seen in the conveying direction » Conveyor belt 1. A guide wall B runs along its right edge.

The incoming objects 2 are counteracted by the roller 7

the longitudinal center plane of the conveyor belt 1 and from to the bend 5b

the adjacent part of the guide wall 5 again in its longitudinal direction aligned.

As a result of the deflection of the objects on tier roller 7 arises a wedge-shaped gap 14 between the adjacent end walls. At the point at which this gap arises a light barrier consisting of a light source 9 and a photocell 10 is arranged. The signals from the photocell can be used for Various purposes can be used, e.g. for counting the objects passing through or for controlling processing operations on the objects and the like.

The roller 7 is driven by the deflection roller 3 via two pairs of bevel gears 11, 12 and a shaft 13 in such a way that its peripheral speed the (jüschw-i ndigktii I deu conveyor belt 1 corresponds. As a result, very gentle treatment of the objects 2 is achieved.

Of course, the roller could also be freely rotatable, but not driven. Cs could uuc: h instead of the role a fixed deflector may be provided.
