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, the basket of the 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 body, one sheet of material is bent into a single unit, forming the 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 - a closed state for storing the product, and an 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 smaller than the angle formed by the upper inclined surface and the horizontal plane (Patent US 2010044116, G01G 13/16; G01G 19/32, 02/25/2010).

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 wet sticky finely and medium-fraction product, for example, when working with cottage cheese, this product will stick to the walls of the body and the sash. Such sticking of the product does not allow us to properly form the required final dose, since not all weighed product falls into the final dose in the measured parts of the dose - some of this product remains adhered to the leaflet. Over time, the adhering product becomes more and more, which impedes the normal operation of the entire weight combination dispenser.

Thus, the described sticking of the product is unacceptable during dosing, since when the product sticks to the basket leaf, the final dose will significantly deviate 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:

- the ability to work with wet sticky finely and medium fractional products without sticking the product on the inner surfaces of the basket;

- 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 basket of the combination dispenser, 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 lower end of the basket with the possibility of opening and closing, each leaf is made in the form of a horizontally oriented plate pivotally mounted on the basket with the possibility of complete displacement to the side.

The shutter can be made in the form of a convex plate.

The leaf can be pivotally mounted on the basket with the possibility of complete displacement to the side along the arc.

The leaf may be provided with at least one plank intended for fastening this leaf to the basket.

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 not 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. Thus, the sash can be attached directly to the basket, or to an additional bracket, which is specially designed for fastening the sash. In addition, the sash can be provided with a strap, which in turn is attached to a basket or other auxiliary element (for example, an arm). There can be two such bars to increase the reliability of the structure. 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.

The material from which the sash is made can also be any. It is advisable to use metal or hard plastic, as these are the most durable and resistant to deformation materials.

Most often, the valves are made in the form of metal plates fixed on a basket like a duck's beak. The specified metal plates may be one or two. These flaps allow dispensers to work with most bulk products. However, such flaps do not allow the dispenser to work with sticky medium and fine products such as cottage cheese. In the described analogues, the cottage cheese begins to stick to the leaves, the weighted dose is not transferred further along the food tract in full, which distorts the final weight. Due to their design, the shutters cannot open the adhering product completely when opened and continue to work with weight distortion. Over time, the sticking of the product on the flaps increases, which leads to a stop in the operation of the dispenser. Such a dosing process is unacceptable, because it does not allow you to get the correct final dose and does not allow the dispenser to work smoothly.

In the proposed technical solution, the sash is made horizontally oriented. It is advisable to perform the sash in the form of a plate, which in its shape and size coincides with the bottom opening of the basket, since in this case the product will not wake up. Most often, this is the shape of a circle or rectangle. The described orientation of the sash in space allows you to freely accumulate the product in the basket and transfer it further along the food path without spilling.

In order to prevent the product from sticking to the sash, the claimed technical solution provides for hinged fastening of the sash on the basket, which allows the sash to move to the side when opened. In other words, when opening the sash, it does not just deviate to the side like a door, as it happens in the analogues and prototype, but moves off to the side, glides in the direction perpendicular to the food path and the basket itself. Thanks to this solution, the product, even adhering to the sash, is cleaned by the side wall during the opening of the basket, and the entire weighted dose goes further into the food path. Thus, due to the proposed design, it becomes possible to eliminate the sticking of the product on the basket leaf, which means that the inventive device provides full, uninterrupted and accurate work with a sticky medium and fine product.

It is advisable to fasten the sash in such a way that when the sash is opened, it is shifted to the side along the arc - in the manner of a swing. In other words, in the described embodiment, when opening the sash does not just shift to the side, but moves along an arc to a vertically oriented position, which makes the basket less bulky. In order to make the design more convenient in operation, it is proposed to perform the sash in the form of a convex plate. Due to the presence of this convexity, the sash can slide more smoothly along the arc when it opens.

In order for the dose of the product from the basket to fall further into the food path in full, it is necessary that the said mixing of the leaf occurs completely. In other words, the leaf should move and open the bottom opening of the basket completely to prevent product jamming on the 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 general view of the accumulation basket of a combination dispenser.

In FIG. 2 shows a side view of the accumulation basket of the combination dispenser.

In FIG. 3 shows a general view of the accumulation basket of the combination dispenser in the open state.

In FIG. 6 shows a side view of the combination basket weighing basket.

In FIG. 7 shows a general view of the weight basket of the combination dispenser in the open state.

In FIG. 8 shows a side view of the combination basket weighing basket in the open state.

According to the drawings, the inventive combinational dispenser 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 of the basket there are two guide elements 2 arranged in the form of two 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, a sash 3 is mounted, equipped with a drive (not shown in FIG.), Which opens and closes it. Also, the inventive basket combinational dispenser contains a pair of slats 4, intended for fastening the inventive basket to the combinational dispenser.

The shutter 3 is made in the form of a quadrangular convex metal plate. In the closed state, the sash 3 is located in a horizontally oriented plane and completely closes the lower opening of the inventive basket.

For fastening the sash 3 to the claimed basket, two strips 5 are provided in the design. In the described embodiment, the strips 5 are made as a single welded structure with the sash 3. In practice, the strips 5 can be made separately and connected to the sash 3 by any rigid connection, as detachable, and one-piece.

The strips 5 are made on two opposite sides of the sash 3 and pivotally mounted on the strips 4. Fastening the strips 5 directly to the basket can lead to a leak in the basket, which will negatively affect the operation of the entire combination dispenser, so it is advisable to fasten the strips 5 to other additional elements (such , as strips 4), capable with such fastening to ensure complete and unhindered opening of the sash.

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. Typically, guide elements 2 are provided with storage baskets that are located on the upper tier of the combination dispenser. The lower weight baskets generally have no guide elements 2. The product enters the weight basket due to the fact that the cross section of the weight basket is insignificant, but larger than the cross section of the storage basket. After the product has entered the hollow through element 1, it is oriented along its side walls. The leaf 3 is thus closed, and the product fractions are located on this leaf 3. Due to the fact that the leaf 3 is convex, the main volume of the product accumulates precisely in the bulge, that is, in the center of the leaf 3. Thus, the product is concentrated in one place, it does not accumulate at the edge of the leaf 3, and therefore does not wake up past the basket. When this basket is selected in combination, the drive drives the leaf 3, and it opens. The process of opening the sash 3 is as follows. Under the action of the drive, the sash 3 begins to shift (slide) to the side perpendicular to the direction of product movement and perpendicular to the side walls of the basket. The shift of the sash 3 to the side occurs along an arc, which is explained by the proposed design. In other words, the sash 3 moves in a circle around the pivot point of the strips 4 and 5 in the manner of a swing. Such an offset allows for the compactness of the basket, which means to increase convenience during its operation. With the described shift of the sash 3 to the side, that is, when it is opened, the product is poured into the unit located below, that is, it is transmitted further along the food path. For a complete discharge of a portion of the product, the sash 3 moves completely to the side, that is, it does not overlap the bottom opening of the basket. The adhering parts of the product, when the leaf 3 is displaced, encounter one of the side walls of the basket and, with further displacement of the leaf 3, are scraped off by this side wall. Thus, on the leaf 3 there are no sticking parts of the product, and the whole weighed or measured portion of the product in its entirety is transferred further along the food path. After dumping a portion of the product, the sash 3 closes again, returning to the opposite position.

Thus, a more accurate dosing process is achieved at a more comfortable operating characteristics of the baskets - the compact size of the baskets, the absence of product sticking on the basket leaf (the entire measured portion of the product is transferred for further processing and the formation of the final dose).

The claimed technical solution eliminates the shortcomings present in such solutions and allows the production of combination batcher baskets capable of accurately and accurately dispensing sticky finely and medium-fraction products, such as cottage cheese or wet animal feed, excluding the possibility of spilling and sticking inside the basket on the sash. 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.
