Abstract

The invention relates to the control and sorting technology and allows to increase the accuracy of control and reliability of operation. Tubes from the hopper 2 are individually sunk into the longitudinal grooves of the drum 4. When the drum 4 rotates from the tube drive, it is fed to the measuring device 8, the bar of which with its basing tips lifts the end of the tube and brings it to the spring-loaded prisms, as well as to the measuring rod. The other end of the tube rests on the support bar during the measurement. The movement of the measuring rod is transmitted to the photovoltaic system, from where the signal about the measurement results is fed to the electromagnets. When one or the other electromagnet is switched on, the corresponding comb 35 or 36 is turned, and the tube enters the hopper 32 or 33. 6 silt (L oo co

Description

The invention relates to a sorting control technique and can be used, in particular, for sorting glass tubes, for example thermometer capillaries,

The purpose of the invention is to improve the accuracy of control and reliability of the machine.

plates A2 and 43. The control system of the machine is located in the console I1.

The machine works as follows.

Glass tubes 44 from the hopper fall into the longitudinal grooves of the drum 4, by means of a periodic rotation, and are transported to the measuring device 8. At this moment, the bar 15 rises from the drive and lifts the edge of the tube 44 with its clamping tips 19. prisms 20 and 21. Polo) ((the measurement of measuring rod 23, depending on the diameter of tube 44, is transmitted through a rychuy system to the mirror 30, with the aid of a traumatic mechanism — JQ, for which the beam of light falls on sports Consisting of one of the photosensors povorot- 31.

39, through a lever system, one of the combs 35 or 36 is rotated, if necessary, so that it enters the annular grooves of the drum 4. When the drum is rotated again, the sorted tube enters the corresponding hopper 32 or D3. If no signal comes from one of the electromagnets, the tube drops out into the hopper 34. At this, the sorting cycle ends.

The measuring device 8 includes a bar 5 with two guides 16 and springs 17, Nlanka 15 is installed with the possibility of vertical reciprocating movement from the pusher 18 connected with the actuator 5. On the bar 15 three flat clamping tips 19 are mounted, above the bar 15 on the bracket 9, two prisms 20 and 21 are placed with springs 22 and a measuring spring-loaded rod 23 connected through a stop screw 24 of the lever 25 with a rail 26 and a gear wheel 27 of a photoelectric converter. The photoelectric converter consists of a light source 28, an optical system 29, a mirror 30 mounted on the wheel 27, and three photo sensors 31.

The sorting mechanism 10 consists of three bins 32-34, rotary combs 35 and 36 mounted on axes 37 and connected with electromagnets 38 and 39 by means of levers 40 and 41. To prevent the tubes from falling out, limiting
