Description

The invention relates to a control and sorting technique and can be used to sort fragile, for example glass, articles.

The aim of the invention is the expansion of technological capabilities.

FIG. 1 schematically shows a device, a general view; in fig. 2 - kinematic diagram of the drive of the sorting drum; in fig. 3 - double ratchet; in fig. 4 is a block diagram of the device.

A device for dimensional sorting of parts comprises a hopper 1 with a gate 2 installed in the upper part of the housing 3 of the device. Below the bunker 1, a transporting rotary drum 4 with slots 5 is mounted for accommodating glass tubes b, kinematically connected by means of a gear 7 to an electric motor 8. A gear 7 with a rotary drum 4 is kinematically connected by a chain transmission 9. The photosensor 11 is positioned on the movement path of the flags 10 . On the path of the glass tubes 6 in the slots 5, a measuring station is installed with a sensor 12, in front of which a supporting surface 13 is installed. Arcuate guide bars 14 are fixed to the housing 3. A sorting rotary drum 15 with sockets 16 for defective tubes 17 adjoins the conveying drum 4. The rotary drum 15 is kinematically connected to the drive 18, for example electromagnetic, which is electrically connected to the sensor 12 of the measuring station. The electromagnetic actuator 18 is connected with the drum 15 by means of a double ratchet mechanism 19, the pawls 20 and 21 of which are mounted hingedly on a spring-loaded lever 22, freely mounted on the axis 23 of the rotary drum 15. On the axis 23, the ratchet wheel 24 and the rotary drum 15 are rigidly mounted - the ratchet wheel 25, which is rigidly connected with the gear wheel 26, which is engaged with the gear wheel 27, which interacts through the gear wheel 28 and the gear wheel 29 with the freewheel clutch 30. The sorting drum 15 has a drive 31 that is defective details. Adjacent to the rotary drum 4, there is installed an outlet glass tube 32, a drum 33, which is kinematically connected to the drum 4. The drum 33 is enclosed in an arcuate guide 34 and has slots 35 for suitable tubes 32.

The detection circuit for defective and suitable tubes 17 and 32, respectively, contains a sensor 12, for example, an electrocontact, and

A position sensor 10 (FIG. 4), for example, a photoelectric, which follows the positions connected to comparison unit 37, the output of which is electrically connected to drive 18, for example electromagnetic.

A device for dimensional sorting of parts works as follows.

A hopper 1 is installed on the device, in which glass is placed in advance.

tubes 6, and the spindle 2 is opened. The motor 8 transmits a rotational motion to the transport rotary drum 4, which with nests 5 captures the glass tubes 6 and transports in the direction of the measuring station.

When each glass tube 6 enters the measurement zone, i.e., passes over the support surface 13 against which the plate spring 36 is pressed, the diameter of the tube 6 is measured in two sections by the sensor 12. The sensor 12 outputs a signal to the comparison unit 37, where at the same time, a signal comes from the photo sensor 11, which follows the positions of the measuring tube 6. If the glass tube 6 does not correspond to the required diameter, the comparison block 37 together with the position signal from the photo sensor 11 generates a signal to the actuator 18 with a delay nym signal through the lever 22, the pawl 20 and the ratchet wheel 24 rotates the drum 15 along arrow A (FIG. 3) so that

its socket 16 for receiving the tube coincided with the socket 6 of the rotary drum 4. The rejected tube 17 falls into the socket 16. Thereafter, the voltage is removed from the electromagnet 18, the lever 22 by means of the spring 38 returns to its original position

and the pawl 21 rotates the ratchet wheel 25 in the direction of arrow B (FIG. 3) together with the gear wheel 26, gear wheels 27 and 28 and the gear wheel 29 (in arrow C), which is the outer race

the clutch 30 through which the shaft 23 is rotated together with the drum 15. In this way, sector 39 of the drum 15 closes the gap G between the arcuate guide bars 14. Thus, with each defective tube 17, the actuator 18, receiving a signal from the comparison block 37, operates that the drum 15 receives the defective tube and closes the slit G with sector 39 until one position of the drum 4 passes.

The suitable pipes 32 are transferred by the drum 4 to the transport drum 33, and then to the tray, from where they are forcibly entered in the oriented position to the receiving hopper.
