Description

(54) DEVICE FOR SORTING DETAILS

t

This invention relates to a technique and technology for controlling and sorting parts in large-scale production.

A device for sorting by weight is known, containing several weighted weights, each of which responds to a predetermined different weight. A series of carriages sequentially moves the object past the weighing assemblies, with each of which has an eject mechanism.

Closest to the proposed technical essence is a device containing a feed conveyor with a group of clamps capable of carrying a weighed object. Measuring stations are placed along the conveyor with sensing elements and sensors electrically connected with the mechanisms of discharge of sorted objects 2.

However, the known device sorts objects according to their weight by comparing the signals of the weight sensor with a given parameter without taking into account the uneven distribution of density and the location of the center of gravity of the objects being sorted.

The purpose of the invention is to expand the technological capabilities of the device for sorting parts into groups according to the moment of force created by them relative to the axis of their suspension.

To achieve this goal, in the device for sorting parts there is a conveyor carrying brackets with axles for hanging parts of sortable parts, measuring stations arranged along it with sensing elements in the form of spring-loaded levers installed in the direction of travel with the possibility of 5 interaction with suspended at the same height details. In this case, the springs of the levers are tared with a decrease in the tension in the direction of transport of the parts.

When the parts and the spring-loaded lever interact, a force shoulder is created, taking into account which it is possible to fix the moment of force with the help of measuring stations relative to the axis of suspension of the part.

The magnitude of the moment of force relative to the axis of suspension is significantly affected by inhomogeneity

0 / main part and location

center of her body. As is known, the center of gravity of parts coincides with the center of inertia, the location of which affects the dynamic characteristics of the parts.

Consequently, after sorting the parts inside, each group will have identical dynamic ha. characteristics

FIG. 1 shows the device, top view; in fig. 2 - a bracket with a hanging part and a spring-loaded lever with a sensor; in fig. 3 - mechanism for resetting parts. ,

The device for sorting parts comprises a chain conveyor 2 provided with an actuator 1, on which brackets 3 are installed with axles 4 suspensions of sorting parts 5 discharged by the reset mechanism b into the receiving tank 7. To the conveyor parts are fed from the hopper 8 through the tray 9.

The measuring station contains a spring-loaded lever 10 mounted rotatably on an axis 11, connected to the core 12 of the sensor 13 and a spring 14, the tension of which can be adjusted with the help of a nut 15.

The sensor 13 signal transducer is electrically connected with a reset mechanism 6 containing an electromagnet 16 with a movable core 17, which acts on a plate of a spring-loaded ejector 18. The ejectors are mounted on brackets.

The device has counters and mechanisms for marking parts for each group. The number of measuring stations and reset mechanisms corresponds to the number of sorting groups.

The device works as follows.

The bracket 3, with the sorting part 5 being mounted on the axle 4, is moved by the conveyor 2 to the first measuring station. Detsh its side surface presses on the spring-loaded lever 10 with some effort. When the set tension of the spring 1 coincides or is exceeded, the spring-loaded lever 10, turning on the axis 11, moves the core 12 of the sensor 13. The signal from the sensor is converted by the converter into a control signal, including the electromagnet 16 of the reset mechanism 6. The core 17 of the electromagnet 16, acting on the spring-loaded ejector 18, dumps the load 5 from the axis 4 into the receiving tank 7.

When the force generated by the load is less than that specified for this sorting measuring station, the lever 10 remains stationary, the weight 5, having turned on the axis 4, is moved by the conveyor 2 to the next measuring station.

The adjustment of the measuring station is carried out with the help of reference parts during the adjustment period of the device e by adjusting the tension of the springs 14, and the control signal of the sensor 13 is obtained with only one specific reference detail, with a consistent decrease in the spring tension on

each of the subsequent measuring stations.

The proposed device allows for the sorting of parts according to the moment they create.

5 forces relative to the axis of their suspension, which is impossible to do with the help of known devices.

Details, namely centrifugal regulator loads, matched with

0 using the proposed device and installed in the centrifugal regulator of the fuel pump of the internal combustion engine, significantly improve performance

5 regulator and, accordingly, the stability of the engine.

Combining in one device the operations of hanging the parts on the axis, feeding to the measuring stations, sorting, marking, dumping into the right bin and counting the number of parts in groups allows increasing efficiency and production culture.
