(54) DEVICE FOR SORTING CYLINDRICAL

PRODUCTS

I

The invention relates to mechanical engineering, in particular to equipment for sorting cylindrical products by size using rigid gauges.

A device for sorting products comprising a horizontal table mounted on the base, roller prisms and a measuring head 1 is known.

A device for sorting cylindrical articles is known, comprising roller probes mounted on a base, a measuring head with gauges 2.

The closest in technical essence is a device for sorting cylindrical products, containing a horizontal table mounted on the base, having a base roller prism, a vertical drive lift with a roller prism, the distance between the rollers of which is greater than the distance between the rollers of the horizontal table prism, measuring a head with floating gauge brackets and a measuring force generating unit consisting of spring-loaded vertically movable bars, the number of which is the number of gauge brackets.

A disadvantage of the known technical solutions is that the reliability of sorting is low.

The aim of the invention is to improve the reliability of sorting.

5 This goal is achieved by the fact that in a known device for sorting cylindrical articles containing a horizontal table mounted on the base, having a base roller: a roller prism, a vertical Q is a talical front-wheel lift with a roller prism, the distance between the rollers is greater than horizontal table prism rollers, measuring head with floating gauge-brackets and measuring unit

15, consisting of vertically movable spring-loaded strips, the number of which is equal to the number of calibrations, the measuring force generating unit has a corrector consisting of spring-loaded earrings and stops placed on

20 of these earrings, while each spring-loaded earring is U-shaped, and the spring-loaded strap is placed in the opening of the earring.

FIG. 1 shows the device in the initial position, front view; in fig. 2 - the device is in the working position, side view (one clip is shown, equipped with a measuring force corrector).

The device comprises a box-shaped base 1, in which a lift in the form of a power cylinder 2 is placed, on the rod of which a lifting roller prism 3 with a large base distance is rigidly fixed. On the uprights 4, the measuring head 5 is cantilevered, the floating rigid gauge skeles 6 are unsupported.

Based on 1, the additional roller prism 7 is rigidly fixed, placed in the space between the upper and lower positions of the prism 3, and there is a small radial distance. Staples 6 are installed in the vertical slots of the head 5.

The measuring force generating unit contains straps 6 placed in the same grooves in the plane of the brackets 6, springs 9 are attached to the opposite ends. 12, interacting with a controlled product in the process of its rise.

Control of pneumatic cylinder 2 pedal Sorting products into groups "Fit," Marriage, is carried out manually on the signals of the scoreboard 13.

The device works as follows.

The products along the guides roll onto the prism 7, the base distance of which is chosen to be minimal (3-4 times less than the corresponding distance of the prism 3).

The operator using the pedal includes a cylinder 2, raising the prism 3, which, when moved to the upper working position, captures the product.

The brackets 6 are pressed by the product into a different position along the spacing or non-spacing, which is fixed on the board 13, while the unit for creating the measuring force can operate in 3 modes:

a) the product has a diameter greater than the limit; clamp 6 is pressed for the full amount of its stroke; the measurement force is generated by the springs 9 and 11;

b) the product has a diameter in the tolerance field; clamp 6 is partially pressed; the measurement force is generated by the springs 9; the springs 11 do not participate in the creation of forces, since the stop 12, interacting with the product, removes the earring 10 with the slats 8;

c) the product has a diameter less than the allowable; the clamp 6 is not pressed, the measuring force is not generated.

Thus, it is possible to correct the measuring force separately by the passage size and the non-passable size of the clips 6 with the help of the corrector 10, at a certain moment removing the load from the bracket.

After reading from the board 13, cylinder 2 is turned off and the product starts to move down. As soon as it comes out of the staples 6, the operator turns him 90 ° on the rollers of the prism 3 and again turns on the power cylinder 2.

The measurement process is repeated. The prism 7 is also made roller to ensure that the product is inspected in the lower position, and also if the lowering speed of the prism 3 is so high that it does not allow the operator to rotate the product in the process of lowering it.

In the lower position, the prism rollers 3 are located below the prism rollers 7 and do not prevent the product from rolling out onto devices on the sorting rack.

This device allows for the correction of the measuring force by separating along the lower limits of the tolerance field, improving the reliability of product sorting and facilitating the extraction of products from prisms.
