SU960074A1 - Apparatus for wrapping round ferromagnetic articles - Google Patents

Description

The invention relates to mechanical engineering and can be applied in other industries for wrapping piece goods such as shafts, axles having a cylindrical smooth surface. 5

The closest to the proposed technical essence is a device for wrapping round ferromagnetic articles, which comprises a feeder shut off, ^{prisposoble-, with} supply of the packaging material and packaging mechanism is configured as a fixed tray and mounted over it swinging endless belt conveyor Li ^{1 !}

However, the known device is unreliable in operation due to the complexity of the design, and also has a large weight. _{2 (}

The purpose of the invention is to increase the reliability of the device by preventing slipping of wrapped products on the tray.

This goal is achieved by the fact that in the device for wrapping round ferromagnetic products containing a feeder with a product cutter, a device for supplying packaging material and a tray for rolling products with packaging material located under it, the bottom of the tray is made of magnetic material, and its input section is hinged on the body of the device, while under the output section of the tray a cam is installed, which is kinematically connected with the cutter.

The drawing shows a device side view.

A device for wrapping round ferromagnetic products includes a product feeder consisting of a guide 1 and a cutter 2 '. The device for feeding the packaged material includes rollers: leading 3 and driven 4, and a knife 5 for cutting the packaging material (tape) 6.

The packaging mechanism contains a U-shaped tray 7, made with a bottom of a flat magnet, the right end of which is fixed by a hinge 8 to the housing 9. The tray 7 has a window of $ 10 for the roller 11 to enter into it to guide the end of the paper tape 6 around the product 12. Under Tray 7 has a working cam 13, the large shoulder of which serves to lift the tray 7 to its original horizontal position, and the smaller - to lower it at an angle X ° to the working position. The working cam 13 is kinematically connected with the cutter 2. Above the tray 15 7 there are two nozzles 14 and 15 for air supply.

The device operates as follows.

A packaging product, for example, the first finger of a track link, when the cutter 2 is activated, falls onto a sheet of paper cut by a knife 5 that was previously fed by rollers 3 and 4, pressing it into the slot between the sides of the tray 7 and the roller 25 and raising its edges. From the nozzle 15 serves air, pre-compress the end of the paper to the product 12.

The cutter 2 is kinematically connected to the working cam 13 · By rotating the cam 13, lower the tray 7, from the nozzle 14, air is supplied, which finally compresses the paper to the product 12. The product 12 is rolled with ₃₅ paper inside the tray 7. The tray, like a magnet, eliminates slipping products, i.e., increases reliability. When the product 12 moves along the tray 7, the roller 11 is recessed into the window 10 of the tray 7. During rolling the product along the tray 7, the ends of the paper from the Highlanders of the product 12 are bent to its side surface and the paper is wrapped around the product 12 to the ends bent to the side surface.

From the tray 7, the wrapped product is placed in a container.

The device for wrapping round ferromagnetic products is reliable and efficient in operation and increases productivity by 1.52 times due to the simplification of the design, reducing weight and reducing the cost of the device.

The packaging mechanism comprises a flat tray 7 with a flat magnet bottom, the right end of which is secured by a shaft ($ 8 to the body 9. The tray 7 has a window 10 for the roller 11 to enter into it to guide the end of the paper tape 6 around the product 12. Under the tray 7, the working cam 13 has a large shoulder which serves to lift the tray 7 to its original horizontal position and a smaller one to lower it by the angle X to the working position. The working cam 13 is kinematically connected with the cutter 2. Above tray 7, two nozzles 1 and 15 are installed for dispensing air. The device works as follows. A packaging product, for example, a pale link of a track, when a cutter 2 is triggered, lands on a sheet of paper pre-fed by rollers 3 and cut with knife 5, pressing it into the slot between the sides of tray 7 and roller 11 and lifting its edge. Air is supplied from the nozzle 15, preloading the end of the paper to the product 12 is performed. The cutter 2 is kinematically connected with the working cam 13. By turning the cam 13, the tray 7t is lowered from the nozzle} k is fed, the air that finally presses the paper to the product 12. Begins rolling the product 12 with the paper inside the tray 7. The tray, like a magnet, eliminates slippage of the product, i.e., it increases reliability. When the product 12 moves along the tray 7, the roller 11 is embedded in the window 10 of the tray 7. During the product rolling around the tray 7, the ends of the paper from the ends of the product 12 are bent to its side surface and the paper is wrapped around the product 12 on the ends bent to the side. From tray 7, the wrapped product is placed in a container. A device for wrapping round ferromagnetic products is reliable and efficient in operation and increases productivity by 1.5-2 times by simplifying the design, reducing weight and reducing the cost of the device. An apparatus for wrapping round ferromagnetic products, comprising a feeder with a device for products, an apparatus for supplying packaging material and a tray for rolling products with packaging material located below, characterized in that, in order to increase the reliability of operation by preventing slipping of wrapped products along the tray, the bottom of the tray is made of magnetic material, and its input section is hinged to the device case, while the output section of the tray is set detecting cam which is kinematically coupled to shut off.
