Description

The invention relates to the food industry and can be used in automatic feeding systems for dispensers and packaging machines for converting the flow of products into rows, mainly fried pieces of fish.

A vibratory feeder is known for converting a product flow into rows containing a vibrating table mounted on elastic elements on which there are guides forming longitudinal channels of constant width and a mechanical agitator to prevent the formation of congestion [1].

The disadvantage of this vibrator is the presence of contact of the agitator with food products, mainly with fried pieces of fish, resulting in crumble products. In addition, the well-known vibratory feeder does not provide a uniform distribution of products in the channels, which causes uneven operation of the devices it feeds, for example, dispensers operating by the method of unit dosing.

The closest in technical essence to the invention is a vibratory feeder for converting the flow of products into rows containing an oscillating table mounted on elastic elements, on which an inclined platform and guides forming longitudinal channels are located. The guides are installed with the ability to change the distance between them [2].

A disadvantage of the known vibratory feeder is that at a constant angle of inclination of the oscillating table with a decrease in the width of the product flow, its density increases, as a result of which some of the products will be delayed before entering the converting channels, forming jams. To avoid the formation of congestion, it is necessary to reduce the supply of products to the converting channels, which reduces productivity.

The aim of the invention is to increase productivity and avoid congestion of products.

This goal is achieved by the fact that in the vibratory feeder for converting the flow of products into rows containing a table mounted on elastic elements with the possibility of oscillatory movement with guides located on it with the formation of channels between them, the table consists of three parts, two of which are flat, located under different angles to the horizontal, and the third is curved, located between the flat parts, and the angle of inclination of the tangent to the curved surface increases from the angle of inclination of one flat part to the angle tilting the other flat part.

Moreover, the channels in the curved section are made tapering.

The drawing shows a vibratory feeder for converting the flow of products into rows, a General view.

The vibratory feeder for converting the flow of products into rows contains an oscillating table 1, consisting of two flat parts 2 and 3, located at a certain distance from one another at different angles of inclination to the horizon. Parts 2 and 3 are connected by a curved part 4. The angle of inclination of the tangent to the curved part 4 gradually increases from the angle of inclination of the flat part 2 to the angle of inclination of the flat part 3. The oscillating table 1 mounted on the elastic elements 5 has ribs 6 and guides 7, which form channels for forming rows of products 8. The channels formed by the guides 7 on the curved part 4 are made tapering.

Vibration feeder for converting the flow of products into rows works as follows.

The stream of randomly located products 8 enters at a constant speed from the flat part 2 of the table 1 to the narrowing channels of the curved part 4. The width of the input part of the channels is greater than the linear dimensions of the products (fried pieces of fish). From the theory of vibrotransportation, it is known that the speed of movement is greater, the greater the angle of inclination of the surface to the horizon. Thus, on the curved part 4 of the table 1, the speed of the products in front is always greater than the speed of the products coming behind. This allows you to reduce the width of the stream without increasing its density and eliminate the gap. When the speed of the products 8 reaches a value that allows them to move one after another at the same speed, the curved part 4 goes into a flat part. The guides 7 of part 3 are parallel to one another.

The application of the invention will improve productivity by increasing the speed of movement of products in 3-7 times.

The presence of a curved part on the oscillating table, on which the narrowing channels are located, eliminates the formation of congestion in front of the converting channels and in the channels themselves ..

In addition, using the difference in the angles of inclination of the flat parts (practically these angles lie within -0 10 °) of the oscillating table, as well as the frequency and amplitude of the oscillations, the product flow can be converted to any number of channels of any width.
