Abstract

SUMMARY OF THE INVENTION: the device is intended for sorting, mainly small screws, and comprises a vibrator connected to the feeder, provided with a sorting element located thereon, and receiving drives. The sorting element is made in the form of a ring having inclined walls, located at an angle to one another and forming a V-shaped groove, while on the outer wall there is a U-shaped groove and through windows, and from the inner one in sections located beneath the through windows, there are rounded notches whose length is equal to the width of the corresponding windows. Through windows are arranged in order to increase the size of the windows. 1 s I. f-ly, 2 ill.

Description

The invention relates to a control and screening technique and can be used in instrumentation. The need to create the proposed device is due to the fact that during the assembly of the watch there is a reassortment of screws, since the pad, the screws are mixed.

A known apparatus for sorting fasteners comprising a feeder, sorting rulers for the purpose of variable cross-section, a vibrator associated with the sorting rulers, and receiving drives for sorted fasteners. The disadvantage of this analogue is that this installation is designed to sort large fasteners according to one of the sizes.

Another analogue is known. An automatic machine for controlling and sorting parts

which uses a rotating bunker. The disadvantage of this machine is that the design of this device does not allow sorting of small watch parts of complex shape,

A device is known that is described in the book of A. N. Robinovich. Automatic orientation and loading of piece parts, Kiev, Technika, 1968, pp. 198-199, Fig. 95. The device is made in the form of a vibrating multi-hopper hopper. The spiral trays of the vibratory hopper have annular platforms with shells at the outlet. In the shells there are windows for delivering parts; the number of windows is equal to the number of distributed streams. The annular areas along which the parts move are inclined planes.

carried out by their configuration (bolts and nuts). Sheath windows are designed to provide parts. The number of windows is equal to the number of distributed streams.

The disadvantages of this device are: the complexity of the design of the device, sorting of parts only according to their configuration, sorting of large parts.

It is also known a device selected as a prototype, containing a feeder, sorting rulers located underneath it, forming a slit of variable cross-section, a vibrator associated with sorting rulers, receiving drives, sensitive elements located at different levels, as well as located in the grooves of the sorting lines mechanisms for dispensing fasteners pivotally mounted on the sorting rulers and connected to the drive mechanisms, while a slot of variable cross section is located in a vertical plane.

The disadvantages of the prototype are: the complexity of the design of the device, sorting of large products.

The aim of the invention is to simplify the design. The expected benefit from using the proposed device is that complex elements are replaced by simpler ones. The device is becoming cheaper to manufacture. In addition, the present invention allows to increase labor productivity by half due to the automated sorting of different-length watch screws

The essence of the solution lies in the fact that the device comprises a feeder connected to a vibrator, a vibratory hopper. A sorting element is made on top of the vibrator bowl, made in the form of a ring having inclined walls located at an angle to one another and forming a V-shaped groove, on the outer wall of which there is a U-shaped groove and through windows, and on the inner wall of the ring, in areas located under through windows - rounded notches. The length of these recesses is equal to the width of the corresponding windows. Through windows are arranged in order to increase the size of the windows. The chamfers are made on the outside of the windows. The orienting part of the ring, i.e. the part into which the screws from the hopper come in is designed so that the largest portion of the orienting part

consists of two walls, which are necessary for the accumulation of screws and their further orientation. In this section, part of the screws is inserted into the U-shaped groove and continues to move along it.

Unsteady screws fall back into the hopper, since the second (inner) wall in the subsequent section is involved. Further along this wall serves as a support for the screws.

In FIG. 1 shows a device, a General view; in FIG. 2 - ring.

The device for sorting fasteners contains a vibrator 1 connected to the feeder (Fig. 1) located on

the vibrator sorting element 2, made in the form of a ring, containing the orienting part 3 (Fig. 2), the feed part regulator 4, the annular groove of the U-shaped form 5, made, as well as through windows

6, on the outer wall 7 of the ring, trays 8 (Fig. 1), mounted on the vibrator bowl, receiving drives 9. The inner sides of the walls 10 (Fig. 2) of the ring, located at an angle of 90 °, form a V-shaped groove. On the

rounded grooves are made on the inner wall of the gutter in areas located under the through windows (Fig. 2, c), the length of which is equal to the width of the corresponding windows.
