Description

The proposal relates to bunker devices intended for supplying a stream of food and non-food piece products, for example, to transporting devices for moving them to dispensers of packaging equipment.

The offer can be used as part of lines for filling and packing piece goods up to 100 mm long, for example, gingerbread cookies, crackers, sweets, dryers, cookies in packages of heat-sealable materials.

A bin for cohesive materials is known from the prior art, comprising a housing and a funnel with an outlet that surrounds it around the perimeter (see RU patent No. 2225887, B 65 D 88/66, 2005).

The known device prevents jamming of the product at the outlet of the hopper with the help of a lever-hammer and the movable connection of two parts of the housing.

The disadvantage of this device is that these means of destruction of the vault are suitable only if the arch or mash is formed by fine materials. Such a bunker is not suitable for unloading piece goods up to 100 mm long in order to destroy a blockage, for example, from gingerbread or crackers, wall vibration alone is not enough. The firing lever cannot also be considered an effective tool against jamming the product, since it is placed at the outlet of the hopper, because of this, during the impact, coarse products are even more stuck in the outlet.

Also known is a device for unloading bulk material from a hopper, comprising a housing with an outlet and a trough,

made in the form of a wedge with an angle of inclination to the horizontal and a wavy surface of the sinusoidal profile (see patent RU No. 2014276, B 65 G 65/23, 1994).

This device is designed for unloading coarse material from the hopper. The gutter installed at the outlet of the hopper reciprocates and advances the product into the discharge window.

The disadvantages of the known device are the design complexity, large dimensions and high energy costs. This device cannot be used for products such as gingerbread cookies or crackers, as they will deform under the influence of a wave trough. At the same time, product congestion at the outlet of the hopper is not ruled out due to the size and shape of piece products like gingerbread cookies.

The closest in technical essence to the claimed solution is a bunker device containing a hollow body, open at the top for product inlet, tapering down by inclined walls to form a product exit hole and equipped with a mechanism for collapsing arches (see patent RU No. 2145301, B 65 D 88/54, 2000).

In this device, to prevent congestion at the exit of the hopper, an exhaust window is provided, which is installed with the ability to change dimensions, namely to expand. For this, the front wall of the hopper is hinged and equipped with return springs.

However, the use of springs to displace the walls of the hopper reduces the reliability of the known device and complicates its design. At the same time, this technical solution does not exclude product congestion, since the indicated wall displacement has limits restricting the product exit zone.

The technical result of the proposal is to ensure a stable product flow from the hopper by preventing

jamming the product with a sufficiently large size using a simple design reliable and easy to use.

To achieve the technical result, in a hopper device including a hollow body, open from above for product inlet, tapering down by inclined walls to form a product outlet, and equipped with a mechanism for collapsing arches, according to the proposal, the mechanism for collapsing arches is made in the form of a agitator, including a horizontal drive shaft located inside the housing with at least one blade mounted thereon, mounted with the possibility of oscillatory motion.

The presence of distinctive features, namely, the implementation of the mechanism for collapse of the arches in the form of a agitator, including a horizontal drive shaft located inside the housing with at least one blade mounted on it, installed with the possibility of oscillatory motion, indicates the conformity of the claimed technical solution with the patentability criterion " novelty".

The essence of the proposal is illustrated by drawings, where figure 1 shows a General view of the hopper device in a perspective view, shown with conditionally transparent walls of the housing; figure 2 shows a General view of the bunker device in a perspective view; figure 3 presents a General view of the mechanism for the collapse of the arches, specifically agitator; figure 4 schematically shows a General view of the line, including the inventive bunker device, conveying device and packaging machine model "PITPACK".

It should be noted that in the drawings for clarity only those details are presented that are necessary for understanding the essence of the technical solution, and related equipment, well known to specialists in this field, is not shown in the drawings.

The inventive bunker device can be used independently or in combination with various food or technical

equipment. In the presented example of a specific embodiment, the hopper device is combined with a conveyor feeding the product to a weighing batcher installed on the PITPAC model filling and packaging machine (Fig. 4).

The universal high-performance vertical PITPAK automatic machine is designed for precise dosing and packaging of a wide range of small, loose, granular, crystalline and piece goods in three-seam bags made of polypropylene film.

The hopper device is shown in figure 1, 2.

The hopper device consists of a frame 1, on which a hollow body 2 is fixed. Frame 1 is a construction of rectangular pipes with four supports, adjustable in height. The housing 2 is installed in the upper part of the frame 1 and is made from above open for product entry and tapering downwards, essentially it is composed of four inclined walls. The housing 2 is an integral structure of a metal sheet bent to form the above side walls. In a cross section (a section parallel to the horizon), the housing 2 is a rectangle that differs in area in sections of different height. The bottom of the housing 2 is partially formed by an inclined panel for directional supply of the product to the product exit zone. Also, the role of the bottom is played by a tray 3, mounted directly under the lower part of the housing 2. In the lower part of one of the side walls of the housing 2 there is a hole for the outlet of the product. The outlet for the product is equipped with a shutter, allowing you to change the size of the hole depending on the size of the product.

The hopper device also includes a mechanism for caving in the arches, namely, a tedder, which is located inside the housing 2. The tedder consists of a shaft 4 and a blade 5, mounted on the shaft 4 with the possibility of oscillatory movement from the pneumatic cylinder 6. The shaft 4 is installed in bushings placed on the cross members from metal corners mounted on frame 1 from two opposite sides of the housing 2.

The device operates as follows.

The product 2, for example, gingerbread, is fed into the open housing 2. The product through the inclined walls and partially inclined bottom evenly, without accumulating, enters the outlet. A vault of gingerbread is not formed, since the blade 5, oscillating in the form of a pendulum, then in one direction, then in the other direction, prevents the accumulation of the product. As a result, a constant flow of product enters the tray 3, which freely extends beyond the body 2 and enters the conveyor, which feeds it further to the weighing batcher of the packaging machine.

The inventive design solution prevents congestion of the product due to the constant alignment of the product flow and its uniform supply to the exit zone of the device. The device provides a stable product flow with a sufficiently large size.

The device was developed and manufactured at the TAURAS-PHOENIX engineering plant and was successfully used at the customer’s enterprise.

From the above it follows that the manufacture of this device in an industrial way does not cause difficulties, involves the use of developed materials and standard equipment, which indicates the compliance of the claimed technical solution with the patentability criterion of "industrial applicability".
