Description

one

This invention relates to devices for automagical feeding of wrapping and packaging machines with piece goods, for example refined sugar, confectionery and other | and M) can be used in the food and confectionery industry, in the production of refined sugar, as well as in the engineering and mining industries of the national household.

A known feeder of piece products to wrapping machines contains an orienting disk fixed on a shaft, rigidly connected with a screw box mounted above it with a horizontal section, covered by a fixed board with a slot that passes into a diversion cann l.

A disadvantage of the known feeder is the presence of a large slush of sliding moving oriented products, which leads to a significant abrasion of sugar. In this case, the products along the screw tray move in slipping mode at low speed, which leads to low productivity.

In addition, the rotational speed of the disk is quite high and necessary to enable the products to be transported along the screw tray (10О-2ОО rpm), as a result of which the speed of the products at the outlet of the feeder significantly exceeds the conveyor speed of the wrapping machine, which makes it difficult to transfer products from feeder to the conveyor and reduces the reliability of its work.

The aim of the invention is to increase productivity and reliability of operation.

The goal is achieved by the fact that in the proposed feeder, under the orienting disk, an additional disk is axially connected to the latter by means of an elastic from the axis, while a vibrator is placed between the disks, consisting of two parts, each of which is fixed on one of the disks with the possibility of interacting with another part

In addition, a visor is located above the horizontal section of the screw tray.

FIG. 1 shows schematically the supply of piece goods to wrapping machines; is a plan view; FIG. 2 is a section along A-A in FIG. one.

Pigagel includes a loading bunker 1, a vibrologlade 2 located below it, an orienting disk 3 and an additional disk 4 located above the disk 3 of a screw logo 5 with a horizontal section 6, covered by a fixed side 7 with a slot a, turning into an outer channel

8 for products .JQ

The orienting disk 3 is rigidly connected with the screw tray 5 by means of a rack 9. The horizontal section of the screw tray 5 is bounded by a wall 10 and a visor installed above it 11.15

An additional disk 4 is mounted on the hollow shaft 12 under the disk 3 and connected to it by means of an elastic system containing glasses 13, springs 14 and guides 15, while glasses 13 are rigidly 20 fixed on the orienting disk 3, and guides 15 on disk 4 .

Between the disks 3 and 4 there is a BH6parops consisting of a core 16 and an electromagnet 17, with the measles fixed on the disk 3, and the 25 electromagnet on the disk 4 with the possibility of interaction with one another. Electromagnet 17 through) Hollow shaft 12 and current collector 18 are connected to the power grid.

The feeder works as follows. zo

The products are periodically poured into the hopper 1 and the vibrating dispenser 2 is uniformly dropped onto the conical surface of the rotating orienting disk 3. Under the action of centrifugal forces, the products are moved to the periphery of the disk 3, where, in contact with the fixed side 7, they move along it, slipping on surface of the disk 3 due to braking about the board, and then fed to the screw tray 5. As a result of the additional oscillatory movement of the orienting disk 3, the products move to its periphery at insignificant Loss of friction due to the reduction of the slip path.

On the screw tray b, the products are oriented, move along it in the micro-fly mode and exit to the horizontal section 6. The wall 10 prevents the product from falling onto the disk 3 from the horizontal section.

ka 6 when they go into the discharge channel 8. The visor 11 prevents the products that have leaked onto the horizontal section from being oriented as a result of vertical oscillations of the screw tray 5,

Oriented articles, grouped on a horizontal section 6 in one turn of the screw tray 5, portions ksh are pushed through the slot o. The discharge channel 8, -a, is then fed to the conveyor of the wrapping machine.

The proposed feeder is more reliable in operation, provides increased productivity and reduced sugar abrasion by reducing the speed of the screw tray, shortening the slide path of products and their residence time in the pit gel.

The feeder will eliminate manual labor when feeding products into the wrapping machine and replace less reliable vibrating feeders.

Claims (1)
