Description

112

The invention relates to the automation of technological processes and can be used for sorting parts of complex shape with a common characteristic feature and for issuing them in a predetermined position.

The purpose of the invention is to increase the sorting efficiency by controlling the shape and size of the sorted parts.

Fig. 1 shows the arrangement of several similar sorting devices with their recognition and sorting control systems on a common transport tray; in fig. 2 is a view A of FIG. one; in fig. 3 is a section bb of fig 2; in fig. 4 - positions of the sorted parts on the transport tray in the control zone; Fig. 5 is a block diagram of a recognition and sorting control system.

With respect to the general transport tray 1, diversion trays 2 are placed, the number of which is determined by the number of groups of the parts being sorted 3, the same sorting mechanisms and the same for the structure of the recognition control and sorting system 4.

The recognition and sorting control system 4 of each sorting device (FIGS. 2-5) contains a radiation source 5 (their number is determined by the number of sensitive elements operating on a photoelectric control method), a photosensitive element (position photosensor) 6 for measuring transducers (sensor groups) 7 and 8, signal generators 9-11 for each sensor, shaper 12 pulse selection, logical element And 13, shaper 14 command and amplifier 15,

The sorting mechanism 16 is mounted on the transport chute perpendicular to the direction of movement of the parts and has an actuating member 17 that goes out through a slot in the wall of the chute in the control zone.

The slot-mask 18 is made in the wall of the tray 1 and is located between the source NIC 5, the radiation and the photosensitive element 6.

Photosensitive elements of the specified control system. are with the photosensor 6 position and two transducers (group sensors) 7 and 8. As a source

radiation is used, for example, an infrared emitter, as a photosensitive element - a photodiode connected to the input of an operational amplifier. The position sensor is designed to register the desired position of the part 3 on the tray when the mask 18 overlaps with a characteristic feature of the part. Group sensors - measuring transducers 7 and 8 are additional sensors and are designed to fix the part belonging to one group or another (size) depending on its distinctive features and can be inductive, photoelectric or other. In the specific case of the implementation, photosensors are also used as the most accurate measurement of the displacement of the part. The logical element And 13 is designed for the moment of simultaneous movement of signals from all three sensors and is made on the basis of the chip. As a shaper 14 teams used one-shot with adjustable pulse duration. The shaper of 12 selections is built as a shaper of time intervals and executed on a microchip.

The device works as follows.

When passing through the control zone valid (FIG. 4), i.e. located in a predetermined position and having a predetermined size; Sensors 7 and 8 are triggered, and through the driver 10 and 1, they give a signal to the first and second inputs of the logic element 13. At the time the mask 18 is overlapped with a characteristic. which appears the signal that triggers the command driver 14, applied to the sorting mechanism 16 (its electromagnetic drive), which causes the actuator 17 to move towards part 3 and it is pushed into the bypass tray 2,

If a part goes to the control zone (Fig. 3, i.e., the desired size5 but not in a predetermined position on the tray), sensors 7 and 8 are activated, however, mask 18 will not be blocked by the characteristic sign Yes312912

Hoist 3 and the photo sensor position does not work, so the signal at the output of the logic element And is missing and the part passes through the transport lot. ku 1 to the next device for 5 sorting.

If a detail enters the control zone, the size of which differs from the set one, but its position on the lot fO ke corresponds to the specified one, then the date 184

Tweaks 7 and 8 do not work at the same time and despite the overlapping of the mask 18, the command to the sorting mechanism 16 is not delivered, the part goes further along the transport tray 1 (Fig. 4). There will be no impact of the actuating element 17 on the part 3 even if it enters the control zone in a position other than the specified one and has other dimensions (Fig. 4).
