Description

 The claimed group of inventions relates to methods of packaging various items and devices for their implementation and can be used in mechanical engineering, the automotive industry, for example, when packing gaskets under the cylinder head of internal combustion engines, as well as in pulp and paper, petrochemical, printing, food and other industries.

 A known method of packaging items (RF patent 2085453, 65 B 11/02, 1997), according to which a spiral-shaped wrapping of an object or group of objects with the main and additional tapes of a flexible packaging material.

 An essential feature of the known method "wrapping an object or group of objects with packaging material" is common with the essential features of the proposed method.

 The known method provides high-quality packaging of items, however, for its implementation requires sophisticated equipment and significant consumption of packaging material.

 The closest analogue of the proposed method is a method of packaging products, including wrapping products with packaging material moving around the packaging product, and the movement of the packaging material is carried out in two planes located perpendicular to each other (patent application RF 95118182, 65 V 11/04 , published BI 6 from 02.27.98, p.61).

 The essential feature of the closest analogue "wrapping the product with packaging material around the product" is common with the essential features of the proposed method.

 The known method provides high productivity and quality of the packaging, however, to implement the method requires sophisticated equipment that requires significant maintenance costs.

 A device for wrapping a ribbon of piece objects according to the copyright certificate of the USSR 1570947 (B 65 B 11/04, 1990). The specified device includes a drum for holding and feeding the tape of packaging material and a comb installed so that a channel is formed for the passage of wrapped objects, a spring-loaded support for objects, a roll holder, a guide bar for the tape, a copy roller and a pressure roller with grooves and a cam of 2 drives mounted rotatably.

 The essential features of the known device "guides of the packaging material" and "packaging material" are common with the essential features of the claimed device.

 The specified device provides good packaging quality and high productivity, however, it is difficult to maintain and is intended for packaging one type of product.

 Also known installation for packing items (RF patent 2085453, 65 B 11/02, 1997), including a system for transporting packaged items, a device for their spiral wrap, a device for supplying an additional tape of packaging material and supports for packaged items.

 The essential features of the well-known installation of "means for creating support for packaged objects" and "means for transportation (moving)" are common with the essential features of the claimed device.

 The known installation has a rather complicated structure, which makes its operation more expensive and makes it difficult to change packaging for another type of product.

 The closest analogue is a device for packaging products according to the patent application of the Russian Federation 95118182 (B 65 B 11/04, published BI 6 from 02/27/98, p. 61). The inventive device comprises supporting means for supporting the packaged product with the possibility of its movement, dispensing means for dispensing packaging material, wrapping means for creating a circumferential movement of the dispensing means, means for rotating the surface of the packaging material between the wrapping stages and means for rotating the articles in rotation planes perpendicular each other.

 The essential features of the known device “supporting means for supporting the packaged product with the ability to move it”, “handouts”, “packaging material” and “wrapping means” are common with the essential features of the claimed device.

 The specified device allows to achieve high quality packaging, however, it is difficult to operate and it is difficult to readjust it to the packaging of other types of products.

 In addition, when packaging products by known methods on known equipment, a stack of products is formed in which only the sides of the product are covered with packaging material and the products in the stack are pressed tightly against each other. This can cause damage to the surface of the packaged products and does not provide a quick separation of the products during unpacking.

 The problem to which the claimed group of inventions is directed is to create a method for packaging products and devices for its implementation, which allow packaging mainly flat and piece items, for example gaskets under the cylinder head of the engine, in three of six planes, of which two planes are horizontal, with the simultaneous formation of a stack of products in the form of a book in which each product is placed between sheets of packaging material.

 In addition, the claimed group of inventions greatly simplifies the method of packaging products and servicing the device for packaging during operation, provides quick changeover of the device to the packaging of other products, and reduces the consumption of packaging material.

 This product packaging greatly simplifies the unpacking of products, for example on the assembly line of a motor plant.

The problem is achieved by the method of packaging piece, mainly flat, products, providing for the wrapping of products with packaging material around the product. Packaging is carried out by wrapping the products on a device containing a traverse with pins, mounted with the possibility of rotation. Simultaneously with the packaging of each subsequent product, starting from the first, a stack of products is formed, laying each product on the surface of the outer turn of the packaging material after each turn of the beam 180 ^o and stop it. In the foot, each product and the whole foot are wrapped with packaging material in four planes, when the packaging material is wound on the crosshead pins. Before removing the foot, the packaging material is trimmed along one of its vertical planes to form a stack of products in which each product is wrapped in its three planes.

Essential features of the proposed method "packaging is carried out by wrapping the product on a device containing a crosshead with pins", "the crosshead is mounted for rotation", "simultaneously with the packaging of each subsequent product, starting from the first, form a stack of products, laying each product on the surface of the upper turn packaging material after each turn of the traverse 180 ^o and stop it "," in the foot, each product and foot as a whole are wrapped with packaging material in four planes when wrapping the packaging m The material on the traverse pins "and" before removing the foot, cut the packaging material along one of its vertical planes with the formation of a stack of products in which each product is wrapped in its three planes "are distinguishing from the essential features of the closest analogue.

 The set task is also solved by a device for packing piecewise, mainly flat, products containing support means for creating support for a packaged product with the possibility of its movement, dispensing means for dispensing packaging material and wrapping means for creating a circular movement of the dispensing means. The supporting and wrapping means are a traverse with two guides and pins for laying products and winding the packaging material, equipped with a turning mechanism and a knife for cutting the packaging material mounted on one of the pins. Handout means comprising a packaging material unwinding assembly, a deflecting roller and a brake.

 Salient features of the inventive device, "supporting and wrapping means are a traverse with two guides and pins for laying products and winding packaging material, equipped with a rotation mechanism" "knife for trimming packaging material mounted on one of the pins of the crosshead", and "handouts contain a node the unwinding of the packaging material, the deflecting roller and the brake "are distinctive from the essential features of the closest analogue.

 The inventive device is also equipped with a frame, drive, controls and control panel.

 The drawing shows the inventive device for packaging products.

 The device has a traverse 1, which is mounted on the spindle of the rotation mechanism 2 and can be rotated around a central axis. On the front surface of the beam there are two guides 3 located symmetrically with respect to the center of the beam. On the guides are attached pins 4 for laying products and winding on them the packaging material with the formation of a stack of products. Traverse with pins in its design resembles a reel used in agricultural machinery and light industry. The distance between the pins, which determines the width of the foot of the packaged products, may vary depending on the size of the product. The traverse rotation mechanism consists of a single-turn clutch, a Maltese cross 5, a traverse disconnect clutch from the drive, and gear control parts connecting the mechanism to the drive (not shown in the drawing). The unwinding unit 6 is used for installation on its axis of the roll with packaging material. The distance between the movable axle stops may vary depending on the width of the roll. The deflecting roller 7 serves to guide the packaging material from the unwinding unit to the traverse. The roller rotates on ball bearings around an axis fixed movably in the horizontal groove of the plate. The position of the roller relative to the crosshead and unwinding unit is adjusted when setting up the device. The brake 8 serves to eliminate sagging packaging material and uncontrolled unwinding of the roll. The brake consists of a lever, which leans back when installing a roll, friction rings and adjustable tension springs (not shown in the drawing). The drive 9 consists of an electric motor 10, a V-belt drive and a worm gear. A safety clutch is mounted on the driven pulley of the V-belt drive. The handle 11 serves to displace the guide pins when removing the stack of packaged products, the handle 12 - to disconnect the yoke from the drive. The pedal 13 is used to control the inclusion of a single-turn clutch and from it by turning the yoke for one cycle. The control panel 14 is used to control the motor, provides power off, the inclusion of signal valves, and also contains a counter of parts and packed stops. A knife 15 is installed on the crosshead 1 for cutting the packaging material. The device is placed in a frame made of welded steel pipe of rectangular cross section.

The inventive method of packaging on the claimed device is as follows. When the traverse 1 rotates, on its pins 4 from the roll 6 through the deflecting roller 7, the packaging material is wound with the tension created by the brake 8. After each turn of the traverse by 180 ^o and its stop, the product is laid on the surface of the upper turn of the film. As a result of winding the packaging material on the pins, a stop is formed with products laid between the layers of packaging material. The foot itself and each product in it are wrapped with packaging material in four out of six planes. Then with a knife 15 cut the packaging material from one of the vertical surfaces of the foot. In this case, a stack of packaged products is formed in the form of a book in which each product is packed in its three planes, two of which are horizontal and one vertical. For ease of removal of the foot, the traverse pins can be reduced to the center.

 Using the proposed method of packaging using the inventive device can significantly simplify the process of packaging products in comparison with known methods, increase its reliability and provides the ability to quickly change equipment to packaging products of a different type. Packaging products in the foot in its three planes greatly facilitates the unpacking of products during their subsequent use, while maintaining good surface condition of the packaged flat products.
