Description

The utility model relates to a weight measuring technique, namely to devices for measuring and weighing portions of a product, and is an element of a weight combination dosing device.

Weighted combination dispensers (they are also called “multi-head dispensers”) is a high-speed and accurate class of machines used for dispensing food and non-food products. The approximate principle of operation of the weight combination dispenser is as follows: first, the dosed product enters the vibration cone (dispenser), which distributes the product along the radial trays; radial trays are equipped with vibrodrives and feed the product into the intermediate bucket (storage basket); an intermediate bucket discharges the product into the weighing bucket below (weight basket); a strain gauge mechanically connected to the weighing bucket measures the weight of the product in the bucket; if the weighing bucket is selected in combination, it opens and the product is discharged into the downstream packing machine by the discharge slopes (Wikipedia: https://ru.wikipedia.org/wiki/Multihead_doser).

The bucket, or in another way a basket, of a weight combination doser is designed to accumulate and weigh individual portions of the product, which will subsequently be components of the final dose of the product. As a rule, the combination dosing basket is a hollow structure consisting of four side walls rigidly fastened to each other and a lower sash fixed to one of the side walls with the possibility of opening and closing.

Known basket containing the body and the sash, which is able to open and close. To form a casing, one sheet material is bent into a single whole, forming a front surface, side surfaces and parts of the support frame. The sash and the lever mechanism of the sash are supported by parts of the support frame (Patent JP 2015151155, B65D 90/62; G01G 19/387, 08.24.2015).

Known basket containing a main body having a tubular shape, which is arranged and designed for installation on a weighing device; as well as a sash connected to the main body with the possibility of opening and closing, the inner surface of the sash together with the main body forming a space for collecting the product, the connection of the sash and the main body is made with the possibility of selective opening and closing - closed state for storing the product, and open state to reset the product; the inner surface of the sash contains an upper inclined surface and a lower inclined surface, which are continuously connected, and the angle formed by the lower inclined surface and the horizontal plane is less than the angle formed by the upper inclined surface and the horizontal plane (Patent US 2010044116, G01G 13/16; G01G 19 / 32, February 25, 2010).

Known basket containing a tubular body with upper and lower holes, which is filled with product through the upper hole; and a discharge flap that opens and closes the lower opening of the housing; the body is formed by a body in the form of a pipe having four or more sides connected together in an annular shape, and the horizontal cross section of the body in the form of a pipe is made in the form of a contour having arched regions and which differs from a rectangular shape; the casing of the basket has a shape in which in the boundary part between adjacent side sides, the angle that is formed between the first virtual plane in contact with one of the sides and the second virtual plane in contact with the other side, and which is located on the inside of the casing, is or exceeds 90 ° (Patent US 2013292191, G01G 19/393, 11/07/2013). This basket is taken as a prototype.

The main disadvantage of all of the above analogues and prototype is the fact that when working with fine-grained products, such as buckwheat, millet, tea, etc., there is a possibility of product spilling between two leaves or between the casement and the body. In some cases, the position of the leaf relative to the basket body may not be correctly adjusted, and therefore a gap may form between the two leafs or between the leaf and the body. In addition, when the dispenser is operating, the basket leaf can become loose, which can also lead to a gap between the two leafs or between the leaf and the body or to increase this gap. In some cases, such a gap is unavoidable, because otherwise the basket doors, when closed, hit each other and make a loud noise. If there are 10 or 14 baskets on the dispenser, the noise from opening and closing the baskets can be extremely loud. To ensure relative silence during operation of the dispenser, the shutters are adjusted so that when closed they do not come into contact with each other. In other words, they leave a gap between the flaps through which the product can wake up.

Such a spill of the product is unacceptable during dosing, since when spilling the product, the final dose will deviate significantly from the required value, which means that packages with the product whose weight does not match the declared on the package will be received.

The task to which the claimed utility model is directed is to create a combination dosing basket, which allows achieving the technical results given below.

Technical results achieved using the claimed utility model:

- increasing the tightness of the basket by eliminating the spillage of the product between the leaves or between the leaf and the basket body;

- expansion of the arsenal of technical equipment designed for dispensing food and non-food products.

Technical results are achieved due to the fact that in the combination dosing basket made in the form of a hollow through element, the side walls of which are guides for the product, and containing at least one leaf, fixed under the bottom end of the basket with the possibility of opening and closing, one of the leafs is equipped with holding shelf.

The holding shelf can be fixed to the lower end of the sash.

The holding shelf may be made of metal.

The holding shelf can be made in the form of a horizontally oriented narrow bar.

The holding shelf can be made in the form of a horizontally oriented gear element.

The combination dosing basket is a hollow through element. This form is due to the fact that the main purpose of the basket is to receive, accumulate and dump a portion of the product. Since there is a need for receiving and dumping a portion of the product, the basket is made through, that is, open on both sides, and to implement the function of accumulating the product, the basket is hollow.

The side walls of the basket are the guides for the product, that is, they direct a portion of the product along themselves inside the basket for transfer to the next processing unit of the combinational dispenser. It should be noted that the opposite side walls of the combination dosing basket can be either parallel or non-parallel. The need for parallelism of the opposite side walls is due to the characteristics of the product and customer requirements. Parallel side walls are universal and allow you to work with any type of product, and non-parallel side walls can, for example, be used when working with products whose individual fractions are long and thin (bread straws), since they better orient the product fractions inside the basket.

The external shape of the combination dosing basket can be any. The most common are those shapes in which the cross section of the basket is a rectangle or circle. In other words, baskets in the form close to a rectangular parallelepiped or cylinder are most common. Such baskets are the easiest to manufacture and use. In addition, the combination dosing basket may be further provided with one or more guide elements. These guide elements are designed to orient the product in space when it is transferred to the basket from the previous processing unit, for example from vibratory trays. The guide element can be made in the form of a plate of metal or plastic and can be mounted on the upper part of the side walls of the combination dosing basket. In some cases, the guide elements are designed so that they are an extension of the side walls of the basket, located around it in the form of petals. In general, the guiding elements do not allow the product to fall out of the basket or fall past the basket when moving from the previous processing unit, they direct the product into the inner cavity of the basket.

The sash of the combination dosing basket is designed to carry out the function of product accumulation, that is, to hold a portion of the product inside the basket for a certain time. To accomplish this task, the sash is fixed under the lower opening of the combination dosing basket so that it is able to open and close under the action of the drive. In the closed state, a portion of the product is accumulated inside the basket, and when the moment of dumping the portion of the product comes, the sash goes into the open position and makes the basket through.

Fastening the sash to the basket can be done in a variety of ways. For example, the sash can be connected to the basket using a hinge element, which allows the sash to open and close at the necessary intervals under the action of the drive, or it can be connected to the basket using movable brackets. The final method of fastening the sash to the basket depends on the requirements of the buyer and the characteristics of the processed product. The type of actuator that opens and closes the leaf can also be any, for example, a pneumatic actuator or a servo.

The number of flaps can be different - one or two. Their number may vary depending on customer requirements and product characteristics.

With incorrect adjustment of the position of the valves or when they are loosened during operation, a gap can form between the valves, through which the product can wake up, thereby changing the final dose weight. In order to prevent such a spillage of the product, one of the leaves is equipped with a holding shelf. The specified holding shelf is designed so that the product could not arbitrarily spill out of the basket.

The supporting shelf is fixed on the lower end of the basket so that it covers the gaps between the wings. Moreover, it should be noted that the holding shelf can be made in the form of a separate element and can be attached to the lower end of the sash, for example, by welding, and can be made as a single part together with the sash. In the case of the holding shelf in the form of a separate element, its fastening to the sash is carried out along the long end. Important is the reliable fastening of the holding shelf to the sash, which can be performed in various ways, depending on the type of product. So, in particular, the holding shelf can be welded or fixed to the sash using rivets. The second option, when the holding shelf is made in the form of a single element with a sash is more reliable, since in this case the structural strength is increased.

It is advisable to carry out a holding shelf in the form of a horizontally oriented narrow bar. The form of execution itself, in the form of a bar, allows you to save material in the manufacture of the basket, while not reducing the effectiveness of the specified shelf. In addition, the shape in the form of a strap is the simplest and cheapest in production and application, and the implementation of a narrow strap gives additional material savings in the manufacture of the holding shelf. It should also be noted that this form is universal for any products, as it limits the loss of individual fractions by covering the entire area of the gap. In some cases, it is permissible to carry out a holding shelf in the form of a horizontally oriented gear element. In other words, in some cases, the holding shelf may not be a simple rectangular bar, but a bar of complex shape having protrusions and indentations like the edges of a notched trowel. This form can be used for special products or if desired by the consumer. It is also possible to carry out the holding shelf of any other forms depending on the processed product and the wishes of the consumer.

The horizontal orientation of the holding shelf is necessary so that the product does not fall off the shelf. If the indicated shelf is made inclined, the product, falling on it, will spontaneously roll and fall into the already formed dose. This product rash is unacceptable in the dosing and packaging process. To avoid this effect, it is proposed to place the shelf horizontally for a more stable position of the product.

The material from which the holding shelf can be made can also be any, but it is advisable to use metal, since it is the most durable and resistant to deformation. In addition, a metal holding shelf will be easier to attach to the basket metal leaf.

The fastening of each basket to the dispenser can be carried out in any way - for example, using brackets that are attached to the basket on one side and rigidly attached to the dispenser. The number of such brackets is not limited and may vary depending on the size of the basket or the characteristics of the product.

The utility model is illustrated by drawings, where:

In FIG. 1 shows a side view of a combination dosing basket.

In FIG. 2 shows a side view of a combination dosing basket in an open state.

In FIG. 3 shows a bottom view of a combination dosing basket in an open state.

According to the drawings, the inventive combination dosing basket comprises a hollow through element 1, made in the form of a quadrangular pipe, of four side walls, which are the guides for the product. On the upper part of the hollow through element four guide elements 2 are arranged, arranged in the form of four petals. In this example, the guide elements 2 are a continuation of the side walls of the hollow through element 1 and are made with these side walls as a whole. Under the lower end of the hollow through element 1 are fixed two wings 3, equipped with a drive (not shown in Fig.), Which opens and closes them. Also, the inventive combinational dispenser basket comprises a bar 4 for fastening the inventive basket to the combinational dispenser.

One of the wings 3 is equipped with a holding shelf 5, made in the form of a horizontally oriented narrow metal strip. The shutter 3 and the shelf 5 are made of one sheet of metal, in the form of a single part, which increases the strength of the entire structure.

In practice, the shelf 5 can be performed on any of the wings 3.

The claimed device operates as follows.

When falling into the inventive basket, a portion of the product is sent exactly inside the basket using the guiding elements 2. In other words, the guiding elements 2 prevent fractions of the product from falling out of the basket and falling outside of it. After the product has entered the hollow through element 1, it is oriented along its side walls. The leaves 3 are closed, and the product fractions are located on these leaves 3. Due to the fact that one of the leaves 3 contains a shelf 5, product fractions do not spill out into the gap between the leaves 3, but are held inside the basket by means of a holding shelf 5, which overlaps gap between the leaves 3. When this basket is selected in combination, the drive drives both leaves 3 and they open. After dumping portions of the product, the leaves 3 are closed again closing. Since there is a gap between the flaps 3, the flaps 3 do not come into contact, which means that there is no noise from the flaps 3 touching, which favorably affects both the entire dosing process and the personnel who serve the dispenser during its operation. At the same time, product spilling from the cavity of the baskets also does not occur, baskets hold fractions of the product inside, as if the leaves 3 were completely closed. Thus, a more accurate batching process is achieved with more comfortable operating characteristics of the baskets - reducing noise, increasing the service life of the wings (due to the presence of the gap, the leaves 3 do not affect each other and their wear is much slower).

The claimed technical solution eliminates the shortcomings existing today in such solutions, and allows for the production of baskets of combination dispensers capable of accurately and accurately dispensing bulk products, eliminating the possibility of spilling them between the basket leaves. In addition, the inventive basket combinational dispenser is quite simple to manufacture and convenient to use.

The combination dosing basket can be manufactured under experimental or mass production conditions.
