(54) DEVICE FOR SUBMISSION OF PRODUCTS IN A TREATMENT AREA

I

The invention relates to mechanical engineering and can be used for supplying products, such as their body shapes to vrash, for example bearing rings to face grinding machines.

A device for supplying products to the treatment zone is known, containing, its feed chute, end cheeks, support bar and a friction drive located above it with an endless traction element and a spring loaded roller 1.

A disadvantage of the known device is that it does not provide the supply of products to the treatment area of a double-sided face grinder due to insufficient feed force.

The purpose of the invention is to increase the feed force.

This goal is achieved by the fact that the friction drive is provided with a number of additional spring-loaded rollers that act on the working branch of the infinite drag element throughout its length, with the magnitude of the displacement amplitude of each spring-loaded roller and the tension force of the endless traction element the required angle of coverage of products with an infinite t element, with each roller being spring-loaded by means of elastic elements in the form of rubber bands mounted on both sides of the role s and the impact on their axes.

In addition, the friction drive is provided with side guides with a working surface in the form of a belt, installed freely in the direction of spring loading of the rollers of the row.

FIG. Figure 1 shows schematically a general view of a device with a detached guide cheek; in fig. 2 shows section A-A in FIG. one; in fig. 3 - section bb in Fig.2; in fig. 4 is a general view of the device designed for supplying products of small diameter; in fig. 5 shows a section B-B in FIG. four.

Claims (3)

The device comprises a bed 1, on which the loading tray 2 and the supporting bar 3 are mounted, mounted to move along the grooves 4. Above the locking bar 3 there is a friction drive 5 that can be moved along the grooves 6 with screws 7 with flywheels 8. after installation into the working position, screw clamps 9 serve. The working branch of the infinite traction element, made in the bidet of the V-belt 10, covering the tension pulley 11 and the drive shchik 12, is affected by the rollers 13, pressing the belt 10 to the supplied products 14, which pass into the grinding zone between the guides of the base 15 and the movable 16 cheeks, rolled by the belt 10, crimping the supplied products 14 on a certain part of the cylindrical surface as a result of the action of the rollers 13 spring-loaded through the axes 17, installed in the grooves 18, rubber bands 19 installed on both sides of the rollers. The V-belt 10 is positioned between the side guides 20 installed loosely in the springing direction, thanks to the windows 21 present in them. The movement of the belt 10 is carried out from the driving pulley 12 connected kinematically to the engine 22 by a chain transmission 23 and a variator 24. Relocatable cheek 16 made of a movable and spring-loaded from the elastic elements 25 to press the product against the opposite base cheek 15 installed in the alignment of one of the grinding wheels 26 of a double-sided face grinder. The device works as follows. According to the diameter of the supplied product 14, the support bar 3 is moved and secured to the frame 1 in the desired position with screw clips 9. After that, the tray 2 is installed in the desired position. Then, along the products 14 installed on the support bar 3, the friction drive 5 is moved with screws 7 to ensure a reliable contact between the working branch of the V-belt 10 and the products 14. By the products 14, the cheek 16 is also installed with the required clamping to the base cheek 15. The device for feeding products works as follows. The supplied products 14 are placed in the loading chute 2, from which, under the action of their own weight, they roll into the zone of action of the friction drive 5. Due to the fact that the working branch of the V-belt 10 is pulled down by the spring-loaded rollers 13, the products 14 fall into the gap in the feed direction and smoothly gripped by the moving belt 10, which compresses the product along a certain arc as a result of the action of the sprung 5Ix rollers 13, the axes 17 of which move in the grooves 18. In the course of the movement, the V-belt 10 the lateral guides 20 are moved in the direction of springing with the V-belt due to the grooves 21. Due to the large contact area along the arc, the V-belt 10 suffers little tension when being rolled by the retaining bar 3 between the cheeks 15 and 16. The products 14 in the process of movement under the action of the friction drive are oriented along the base cheek 15 and enter the grinding zone without distortions. The proposed implementation of the device provides the required angle of coverage of products on the surface of rotation and, as a consequence, an increase in the feed force. Claim 1. Device for supplying products to the treatment area, containing a loading tray, end cheeks, support bar and a friction drive located above it with an endless traction element and a spring-loaded roller acting on its working branch, characterized in that In order to increase the feed force, the friction drive is equipped with a number of additional spring-loaded rollers acting on the working branch of the endless traction element throughout its length, and the magnitude of the displacement amplitude Each spring-loaded roller and the tension force of the endless traction element are selected from the condition of providing the required angle of coverage of products with an endless traction element. 2. A device according to claim 1, characterized in that each roller is spring-loaded by means of elastic elements in the form of rubber bands mounted on both sides of the rollers and acting on their axes. 3. The device according to claim 1, characterized in that the friction drive is provided with side guides with a working surface in the form of a belt, installed freely in the direction of spring loading of the rollers of the row.
