Abstract

The invention relates to the field of accounting and control of items moved along a conveyor. The invention makes it possible to increase the accuracy of the device when counting objects, such as boxes moving along a conveyor. The horizontal fixed axis 3 with probes 6 and 7 is located above the box, the side probes 7 GO on the upper ends of the sides of the box, and the probe 6 or probes 13 sink into the box. The signal from sensor 10 (or sensors 10 and 17) is fed to the recorder 12 pulses. Limiters 4 do not allow probes 6.7 and 13 to move along axis 3; clamp 8 serves to restrict movement of probes 6.7 and 13 after they fall from the sides of the crate passing under the device. The shock absorbers 9 serve to dampen the blows of the probes 6.7 and 13. After the probe 6 (or probes 6 and 13) falls into the box through its upper opening, and the probes 7 are at the upper ends of the side walls of the box, flag 11 goes into the slot contactless sensor 10, the signal from which is fed to the recorder 12. Next, the back wall of the box aligns the probes 6 and 7, S GGHM1

7, strips 5 connecting the ends of the lateral probes 7 placed on the fixed axis 3, the proximity sensor 10

with a flag 1I, an additional flag 18 attached to the end of the middle probe 6 placed on a fixed axis, while the proximity sensor

10 performed as a photocell mounted on one of the vertical posts I, and the illuminator 24 mounted coaxially with the photocell 10 on the second post 1, and the main flag

11 is fixed on the end of one of the lateral probes 7 placed on a fixed axis 3.

The proposed device works as follows.

The horizontal fixed axis 3 with probes 6 and 7 is located above the drawer. When this side probes 7 are on the upper ends of the sides of the box, and the probe 6 (or probes 13) falls into the box.

The signal from sensor 10 (or sensors 10 and 17) is fed to the recorder 12 pulses. Probes 6 and 13 are longer in comparison with probes 7 in order to eliminate false alarms. The stops 4 do not allow the probes 6,7 and 13 to move along the ogi 3. The clamp 8 serves to restrict the movement of the probes 6,7 and 13 after they fall from the sides of the crate passing under the device. The shock absorbers 9 serve to dampen the impact of the test leads 6,7 and 13.

In contact with the front wall of the pschka going along the conveyor 2, with probes 6.7 and 13, it takes them to a certain angle. After the probe 6 (or probes 6 and 13) falls inside the box through its upper opening, and the probes 7 are located on the upper ends of the side walls of the box, the flag 11 goes into the slot of the proximity sensor 10, the signal from which goes to the recorder 12. Next, the back wall of the box aligns the probes 6 and 7, the flag 11 exits the slit of the sensor 10 and a countdown occurs.

When the box goes out from under the device, the probes 6 and 7 fall on the lock

8, with the probes 7 falling with some advance compared with the probe

6, since the latter is somewhat longer, thereby eliminating the false triggering of the device.
