Description

(54) DEVICE FOR SORTING DETAILS

one

The invention relates to mechanical engineering and can be used to sort parts by ruler on automatic lines.

A device for sorting parts by size is known, comprising a conveyor carrying gripping elements, a slope, a main measuring unit, a memory unit and an actuator acting on the gripping elements ij.

The known device does not provide simultaneous sorting of parts of different types, which significantly reduces its performance. A whole invention is to improve the performance of the device and to ensure simultaneous sorting of parts of different types.

To achieve this goal, the proposed jg device has additional measurement units, with the main AND; An additional measurement unit is connected to the memory unit and located with the software size

displacement along the conveyor, the tape of which has from sleep, arranged in a checkerboard pattern.

FIG. 1 shows a view of a device for sorting parts by size; in fig. 2 - Section A-A in FIG. one; in fig. 3 - Sich 1E BB in FIG. 2; on fi. 4, view B in FIG. 2; pas figs. 5 is a block diagram of the device.

Based on the device 1, a conveyor belt containing tape 2 is placed; it is made “1 in the form of plates 3 and 4 with windows 5 and 6 according to the sizes of the sorted rings 7 and c. Moreover, oKiia 5 and 6 are arranged in a checkerboard pattern on the belt 2. The conveyor has fascinating elements 9 and 10, the end working parts of which have different lengths. Moreover, their length is tshsova, which is in one of the most extreme: they are located within windows 5 and 6 and enter the openings of the received rings 7 and 8, and in the other extreme position they lie outside the limits of these windows, and consequently, outside the holes rings. The conveyor is driven by the sprocket by means of sprockets 11 bearing on itself a two-sided roller chain 12. The upper branch of this chain is driven by rollers 13 onto guide rails 14 fixed on the base 1. On the chain 12 with a step equal to twice the pitch, degash, the brackets are fixed 15, on which the plates 16 and 17 are differently fixed with longitudinal grooves 18. In the grooves 18 there are placed freely gripping elements 9 and 1O, above which the horizontal porter belt 2 is located. The device also has two rows of slopes 19 and 20 located respectively under the rows of windows 5 and 6 of the conveyor, and the main 21 and additional 22 measurement units of the sortable rings 7 and 8 with the transducers having moved the measurements into a discrete electrical signal, for example photoelec: trichesky elements. The main and additional measurement units are connected to memory unit 23 and are displaced along the conveyor. Moreover, the outputs of measurement units 21 and 22 are connected to different cells of a shift register 24 for them with an offset at which the number of cells to which the connection of outputs 21 and 22 is displaced corresponds to the number of windows 5 and 6 in the conveyor belt between the units. The memory unit contains, in addition to the shift register 24, dat: pulses 25, which is connected to the conveyor and connected to the memory unit 23. The device’s actuating mechanism acting on the gripping elements 9 and 10 consists of an electromagnetic sorter 26 with actuating elements. in a way. . A continuously moving conveyor takes in windows 5 and 6 ,. from which the pre-gripping elements 9 and 10, measured in blocks 21 and 22, rings 7 and 8, are taken. Moreover, rings 7 and 8 of various types come into windows 5 and 6 located in different rows with a shift in chess order. From the outputs of blocks 21 and 22, which serve to measure various types of rings 7 and 8, the shift register 24 receives a signal about the number of the accumulator into which the ring should go. When the conveyor is moved to one sorting group, pulses of the sensor 25 are produced in the shifting pei-HCTpe 24 of the memory unit 23 of the accumulated discrete electrical signals accumulated there. Signals related to rings of 7 to 8 different types are shifted (together with the movement of the rings on the conveyor itself) in the shift register 24 and the output of actuated elements of the action of the 27 electromotor sorter 26. The elements of the action 27 are kinematically associated with the rings 7 and 8 through the exciting elements 9 and 10, regardless of whether rings 7 and 8 are located in the shm series, and when the chess house is located windows 5 and 6 above the accumulators 19 and 20 with a certain group number there can be only one ring located in one of the rows, and it is reset to its bezoschibochno drive 19 and 20, located at its adjacent Koledov ho type. Photodiodes 28 and light sources 29 are installed along the conveyor against each accumulator. Thus, at the end of the stroke of the exciting elements 9 and 10, the light beam from the source 29 is blocked. Each photodiode is included in the blanking circuit in its cell of the shift register 24, which occurs after the element 27 connected to this cell is energized to move the gripping elements 9 and 10. The arrangement of the windows on the conveyor belt along with others is outlined By other features of the device, it makes it possible to dispense with the simultaneous sorting of parts of various types of flashes in the number of technical means of control. Forms in the case of the invention. A device for sorting parts according to size, comprising a conveyor carrying fascinating elements, accumulators, a main measuring unit, a memory unit and an operating mechanism, which acts on the fascinating elements in order to raise the manufacturer Guests of the U devices ensure simultaneous sorting of parts of different types, it has additional measuring units, the main and additional measuring units being connected to the memory unit and located with displacement s conveyor belt which has a window located in staggered.
