Abstract

FIELD: food industry; packing of soft bags with tea cardboard boxes.

SUBSTANCE: invention can be used in medicine, pharmaceutical and other industries. Proposed device contains conveyor-accumulator, pack shift limiter, transporting device, open holder, gauges and pistons-pushers. Holder is fixed before transporting device near conveyor-accumulator. Transporting device is made in form of rocker installed on horizontal axle parallel to conveyor-accumulator. Gauges are mounted for movement on ends of rocker being made in form of narrowing towards periphery rectangular parallelepiped. They are used to receive packs filled with product and preliminary upset in holder and to render them form of briguette for freely getting into box, being pushed by piston-pusher.

Description

The invention relates to packaging equipment and can be used in the food industry for packaging soft bags with a bulk product, such as tea, in cardboard boxes. The invention can also be used in medical, pharmaceutical and other industries.

Many bulk products, such as tea, are dosed on filling machines in soft bags made of polyethylene and other similar films with a thickness of 0.020-0.030 mm. Such bags weighing 100, 150 g, etc. look like a bag. Packing such a bag in a cardboard box having a volume very close to the volume of the bag is quite difficult, and with automatic packaging, the bags can easily burst. Therefore, to facilitate the entry of such a package into a cardboard box, it must first be sealed and shaped into a box (parallelepiped), and then pushed into the box, after which it can be sealed.

A device for packaging soft piece products, for example soft bags with bulk product, in cardboard boxes containing a transporting device, a receiving table, piston pushers and a limiter for moving packages (SU 1630965 A1, publ. 02.28.1989). In this device, the sealing of the soft product is carried out in the mechanism for packing by crimping the product from all sides. However, in the process of transferring products from the conveyor to the packaging mechanism, which is carried out using a lifting device, there is a high probability of a tear of a thin film. In addition, the known device is quite complicated in design, since the mechanism for the packaging is a multi-link mechanism.

Closest to the invention is a device for packaging soft bags with a granular product in cardboard boxes, containing a receiving table, a limiter for moving packages, piston-pushers, a transporting device made in the form of a disc mounted on a horizontal axis with discrete rotation, on the periphery of which are fixed clips , and rigidly connected with clips caliber (RU 2227109 C1, publ. 04/20/2004).

In the process of discrete rotation of the drum, packages with bulk product are gradually sealed in cages with the help of piston-pushers, and then pushed into the caliber, where they take the form of a briquette, and then into a cardboard box.

A disadvantage of the known device is the bulkiness and complexity of the design of the conveying drum, as well as the complexity of the discrete rotation mechanism of the drum in the form of a Maltese cross. All this does not allow to provide the necessary performance.

The objective of the invention is to provide a device that allows you to easily and without damage to pack soft bags with a loose product, such as tea, in cardboard boxes, which at the same time has a simple design, technologically advanced, easier to manufacture and has high performance.

The problem is solved in that in the device for packaging soft bags with bulk product in cardboard boxes containing a conveyor drive, a bag stop, a conveyor device, an open clip, calibers and piston pushers, the clip is fixedly fixed in front of the conveyor device next to the conveyor- drive, the conveying device is made in the form of a rocker arm mounted on a horizontal axis parallel to the conveyor drive, and the gauges are movably mounted at the ends the rocker arms have the shape of a rectangular parallelepiped tapering to the periphery and are used to receive packets filled with the product and pre-compressed in a clip and finally compacted to form a briquette for free entry into the box when being pushed by a piston-pusher.

Figure 1 schematically shows the claimed device. The device comprises a conveyor drive 2 bags 1 with a bulk product, for example tea, coming from a filling machine, a bag movement limiter made in the form of an elastic plate 3, mounted for free movement to control an inductive sensor 4, a piston-pusher 5 for moving packages 1 from the conveyor-drive 2 to the stationary open cage 6, the piston-pusher 7 for pushing the packages 1 from the cage 6 to caliber 8, having the shape of a rectangular parallelepiped tapering to the periphery, A company device 9 with a rocker 10, at the ends of which calibers 8 are movably fixed, a pusher-piston 11 for pushing the bag 1 from the caliber 8 into the open box 12 and a pusher-piston 13, which prevents the bag 1 from leaving the open box 12 from the opposite side.

The device operates as follows. From the filling machine soft bags 1 with the product, having a shapeless, baggy look, are fed to the conveyor storage 2 and, moving along it, abut against a metal elastic plate 3, which controls the inclusion of the inductive sensor 4. The sensor 4 is activated and gives a command about the presence of package 1 on the piston-pusher 5, which mixes the package 1 from the conveyor-drive 2 into a stationary receiving cage 6. In the casing 6 is a preliminary compression of the package 1 in height and width. Then, the piston-pusher 7 pushes the package 1 from the holder 6 to the caliber 8, in which the package takes the final shape of a rectangular briquette, while the piston-pusher 5 remains in the extreme left position, compressing the package 1 in width. After that, the rotary mechanism 9 rotates the beam 10 by 180 ° around the horizontal axis and the piston-pusher 11 first inserts the movable gauge 8 with its narrowed part into the opened box 12 by 5-10 mm, and then pushes the packet 1 from caliber 8 into the box 12. When this piston-pusher 13, acting as an anti-stop, does not allow the package 1 out of the box.
