Description

 The invention relates to the field of machine tool industry and can be used in the processing of products for passage on centerless grinding machines.

 A well-known sector orientation mechanism containing a hopper for products moving in the hopper reciprocating sector, a ejector and a movable chain conveyor, providing the supply of products to the machine on a horizontal section (see Malov A.N. Loading device for metal cutting machines. M .: Mechanical Engineering , 1972, p. 64, Fig. 41b).

 The device operates as follows.

 Bulk blanks are poured into the hopper. The sector, swinging back and forth from the drive, captures the workpieces and feeds into the groove of the wall of the hopper, tilted towards the chain conveyor. The workpieces slide off by gravity onto a chain conveyor, which, in turn, feeds the workpieces into the machine. Workpieces that are in the wrong position in the gutter are dumped into the hopper with a dumper.

 The disadvantage of this device is the impossibility of supplying products directly to a centerless grinding machine - a chain conveyor is required, the complexity of the ejector design, which ensures the discharge of excess products at the outlet of the hopper. In addition, the inclination of the groove towards the conveyor leads to the fact that incorrectly oriented parts supplied by the gate slide simultaneously along the gate and the groove to the outlet of the products from the hopper and can in some cases cause jamming of the resetting sprocket. Reduced due to the large return of products to the hopper with a dumping device, the performance of the device.

 Also known is a loading device comprising a hopper with a swinging gate, a dispensing mechanism, a bar located at an acute angle on the lower part of the hopper wall, the upper part of the hopper wall mounted on the bar at an acute angle with the possibility of regulation and forming a lodgement for receiving products (see a p. 1340986, MKI B 23 Q 7/06).

 The device operates as follows.

 By turning on the drive, the oriented products are raised by the gate to the lodgement level, correctly oriented products are rolled onto the cradle, due to the tilt of which the products are rolled and their output through the window of the front wall of the hopper. Incorrectly oriented products are returned to the hopper with a dropper.

 A disadvantage of the device is the impossibility of supplying products directly to a centerless grinding machine, the complexity of the design due to the presence of a ejector, the need to tilt the lodgement in the direction of delivery of products from the hopper and, accordingly, reducing the productivity and reliability of the device.

 The closest solution to the technical nature, i.e. the prototype is a sliding mechanism for orienting long rollers, containing a hopper, separated by a partition, swinging on the horizontal axis using cams, springs, rods, rollers, and acting through the supports fixed on the rods of the gates of the gate, the gate, pivotally mounted on the levers, chain a conveyor stretched over two sprockets, one of which is a drive, a ejector, a drive of the device, a crank mechanism, providing movement of the gate, and four chain gears, which ensure the selection power from the drive for the diverter and the chain conveyor (see. Malov AN Filling device for machine tools. M .: Engineering, 1972, p. 63, Fig. 40).

 The device operates as follows.

 Products in the hopper are poured in bulk. When the engine is turned on, the gate with the help of the crank mechanism makes a reciprocating motion, while simultaneously pressing the stops with squares, which, in turn, together with the springs force the partition to oscillate. This ensures the destruction of the arches of products in the hopper and a uniform flow of products to the gate. Products rolled onto the gate are lifted by the gate and fall onto the chain conveyor. The blanks on the conveyor are arranged in one row, the excess ones are removed with a dropper. The rotation of the ejector and the chain conveyor is made from the general drive of the mechanism using chain gears.

 The disadvantage of this device is the presence of a ejector and a mechanism that ensures its rotation, which complicates the design of the device, as well as the inability to feed products of various diameters into the universal centerless grinding machine served by the device.

 The objective of the invention is to expand the technological capabilities of the device and increase its reliability.

 The specified technical result is achieved by the fact that the proposed device is equipped with a vertical ruler mounted above the conveyor along its entire length with the possibility of adjusting the position along the width of the conveyor, and a strap installed on the vertical ruler with the ability to adjust its position in the vertical plane and form together with it and the conveyor lodgement for receiving parts from the hopper, while the gate at the exit of the hopper in the direction of conveyor movement in its upper part is made with a bevel, for example equal to the hull.

 Comparative analysis with the prototype allows us to conclude that the inventive device "Bunker-loading device for rod-type parts" expands technological capabilities and eliminates the ingress of unnecessary or incorrectly oriented parts on the conveyor due to the new features listed above.

 Therefore, the claimed technical solution meets the criterion of "Novelty."

 Comparison of the proposed solution not only with the prototype, but also with other technical solutions in this technical field did not allow us to identify in them the features that distinguish the claimed solution from the prototype, which allows us to conclude that the criterion of "Inventive step".

The essence of the technical solution is confirmed by the drawings, which depict:
- figure 1 is a General view of the device;
- figure 2 is a section a in figure 1;
- figure 3 is a section B in figure 1.

 The device consists of a housing 1 extending between the vertical walls of the conveyor housing 2, a hopper 3 adjacent to the conveyor 2, a slide 4 moving in the hopper 3 along the vertical wall 5 of the housing 1, a vertical ruler 6, mounted on the wall of the housing 1 opposite the hopper, 7, mounted on a ruler with the ability to adjust its position above the conveyor in height. The gate 4 contains in the upper part a bevel directed towards the housing 1, which ensures the capture of parts from the hopper and their rolling when raising the edge of the gate to the level of the conveyor. To prevent capture by the gate of the parts from the hopper, the gate at the outlet of the hopper has a bevel (Fig. 3) directed from the housing 1. At the same time, the tip of the reverse bevel of the gate ensures the discharge of excess, incorrectly lying products in the lodgement formed by the wall 5, the conveyor belt 2, the vertical ruler 6 and strap 7, into hopper 3.

 The device operates as follows.

 Products in bulk are poured into the hopper 3, and with a gate 4, making vertical reciprocating movements, they are oriented along the gate, grab the products and issue on the conveyor bed. Unnecessary items fall back into the hopper together with the descending gate. Incorrectly oriented products that accidentally hit the lodgement, for example, at an angle, can be sandwiched between two correctly lying products and the conveyor, they are issued into the exit zone from the hopper. In this zone, incorrectly oriented products with a bevel of the gate directed away from the body are squeezed out of the tool tray and dumped into the hopper or dropped onto the conveyor.

 Thus, due to the fact that a vertical ruler is installed over the conveyor along its entire length with the ability to adjust the position across the width of the conveyor and a bar fixed on the vertical ruler with the ability to adjust its position in the vertical plane and form a lodgement with it and the conveyor for receiving parts from the hopper while the gate at the exit of the hopper in the direction of conveyor movement in its upper part is made with a bevel directed from the housing, the proposed device is simple and reliable o provides orientation and single-piece delivery of parts, allows you to quickly re-adjust it to any standard sizes of parts.
