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: http://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 these analogues and prototype is the inability to work with sticky and frozen products.

If the baskets described above get inside, products such as prunes, dried dates, chewing marmalade and the like can stick to the cusps, which are a smooth plate. At the moment of opening of these leaves, adherent fractions of the product do not fall out of the basket, but remain adhered to the leaf, that is, remain inside the basket. If such a situation occurs inside a basket connected to a strain gauge or other measuring device, in other words inside a weight basket, then weighing portions of the product will be inaccurate, which means that the final dose of the product will not have the required weight. The dispenser will make up the final dose of the product, taking into account the total weight of the product portions inside the weight baskets, but when unloading inside some weight baskets, several pieces of product fractions will remain, the weight of which will be insufficient in the final dose. And when recruiting the next portion of the product, weighing should be carried out taking into account adherent fractions of the product, which reduces the accuracy and speed of dosing. Such a weighing process is unacceptable, since the final dose of the product will be less by the weight of the adherent fractions, that is, less than the required weight.

In addition to significant errors in the weight of the final dose of the product, adherent fractions of the product lead to frequent contamination of the dispenser baskets. In order to clean the baskets from adhering product, the combination dispenser must be stopped, which will stop the entire production line. Thus, this drawback negatively affects the production process. In addition, this drawback can affect the quality of the dosed product, since during the operation of the combination dispenser, such adherent particles can gradually deteriorate, fall off the sash and fall into the final dose, which means it can reach consumers.

As for frozen foods, they are also prone to freezing to the basket sashes, as are sticky foods. With the so-called "transition through 0", the moisture seizes instantly when the cold product comes into contact with the warm metal. Thus, frozen foods “stick” to the cusp of the basket. All the disadvantages of such adhesion have been described above in the case of sticky products.

Thus, when working with sticky and frozen products, the analogues and prototype will not only become dirty, but also disrupt the entire dosing process due to adherent fractions of the product.

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 sticky and frozen foods;

- 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 bottom end of the basket with the possibility of opening and closing, each leaf is made in the form of the frame on which the mesh material is fixed.

Each leaf can be equipped with at least one stiffener.

As the mesh material, a mesh can be used.

The grid can be made of metal.

The grid can be made of plastic.

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. 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.

In order to prevent products from sticking to the sash at the time of accumulation, the sash is made not in the form of a continuous smooth metal or plastic plate, but in the form of a frame. The specified frame may repeat the contour of the lower opening of the basket, as this is not only more aesthetic, but also more convenient to use. Mesh material is fixed on the frame, which is designed to reduce the contact area of the product with the sash. For sticky and frozen products, such a reduction in the contact area is extremely important, because in the case of the claimed technical solution, the product will not completely touch the surface of the sash, but only pointwise, which will not allow it to stick to the sash. Thus, due to the introduction of mesh material into the sash design, the basket has gained the ability to work with sticky and frozen foods.

The applicant, not only in theory but also in practice, was able to achieve the desired technical result using the inventive combination dosing basket. Due to the reduced contact area between the product and the sash, the surface area of the sash to which the product can adhere has also decreased. In this case, the product is likely to adhere pointwise to the mesh material of the leaf, but after opening it, under its own weight, the product fractions “come off” from the leaf and fall down to the next processing unit of the combinational dispenser. This is because the contact area between the product and the mesh material of the sash is so small that it is not enough to firmly hold the product fraction on the sash. Thus, after dumping the product, no adhering fractions remain in the basket, which in the future can affect both the process and the accuracy of dosing, and the quality of the product itself, which will reach consumers.

As the mesh material, any material having a cellular structure and capable of reducing the contact area of the leaf with the product can be used. For example, a mesh material, metal or plastic, may be used as the mesh material. Using a conventional mesh can simplify the production process of the claimed technical solution and simplify the process of its operation. An important point is the size of the mesh cell - it should not exceed the size of the smallest particles of the product, otherwise the product will wake up through the mesh and the dosing process will be inaccurate. It is advisable to use the smallest cell size, at least 0.4 mm in size, since this size is optimal for working with most products, which gives the claimed technical solution versatility and additional ease of use. Based on the experimental data, 1–1.5 mm can be considered the most optimal cell sizes. Nevertheless, under certain circumstances, taking into account all the features of the processed product, the cell sizes can be greater or less than the indicated optimal values.

As mentioned above, a metal or plastic mesh can be used as the mesh material. The use of a metal mesh is more preferable, since metal is a more durable and durable material than plastic or plastic. However, in some cases, when working with special products, a plastic mesh can also be used, which will allow you to process the product more carefully.

To simplify the design and manufacturing process of the claimed technical solution, it is recommended to use a standardized grid manufactured on an industrial scale for various industries.

In addition to the mesh, perforated sheets of metal or plastic may be used as mesh material. However, the use of a mesh in comparison with perforated sheets of metal or plastic has certain advantages. First of all, a mesh made of threads has a minimum contact area with product fractions, while a perforated sheet has a significant smooth surface between the holes, which is prone to contamination and contributes to the adhesion of product fractions. In addition, the use of the mesh is easier to manufacture, since the manufacture of a perforated sheet of metal or plastic with a minimum hole diameter is quite expensive. It can also be noted that as a result of production tests, the option using the mesh showed the best results - no adherence of product fractions was detected.

The fastening of the mesh material to the sash can be carried out in any way: by welding, soldering, threaded connection using clamping strips. The method of attaching the mesh material to the frame should take into account the type, weight of the product fractions and the size of the combination doser basket itself.

When working with frozen foods or heavy sticky foods, the mesh material can easily deform under the weight of these foods. To add additional rigidity to the mesh material and the entire sash, this sash can be provided with stiffeners. The number of stiffeners can be different and depends on the size of the sash and the weight of the product. It is advisable to place stiffeners on the outer surface of the sash so that they do not come into contact with the product. In addition, it is advisable to perform stiffeners made of metal, since this is the most durable and wear-resistant material. The stiffeners can be attached to the sash in any way that provides a rigid fastening, for example, by welding, riveting or threaded connection.

In addition, the stiffeners can be made integrally from the material of which the sash frame is made. This will reduce the number of detachable joints and strengthen the design of the entire combination dosing basket.

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 front view of a combination dosing basket.

In FIG. 3 shows a top view of a combination dosing basket.

In FIG. 4 shows the cusp of a combination dosing basket.

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 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, two flaps 3 are fixed, 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.

Both flaps 3 of the inventive combination dosing basket are made in the form of rectangular metal frames provided with stiffeners 5. Moreover, these stiffening ribs 5 and the frames of the flaps 3 are made of one metal sheet. In other words, the stiffening ribs 5 and the frame of the wings 3 are cut from one metal plate and represent a single part. A metal grid 6 is attached to the frame on the inside of each leaf 3. A grid 6 is attached to the frame surfaces 3 using metal strips 7 made in the shape of the leaf 3 frame. The metal strips 7 are attached to the leaf 3 frame using rivets.

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 the leaves 3 contain a metal mesh 6, and the product fractions are mainly in contact with it, the adhesion of individual product fractions does not occur due to the small contact area of the product and grids 6. When this basket is selected in combination, the drive drives both leaves 3 and they open. Due to the fact that the product did not adhere to the net 6, the entire portion of the product stored in the basket falls down and enters the further nodes of the combinational dispenser; no loss of individual fractions of the product occurs. The ribs 5 do not allow the metal mesh 6 to deform under the weight of a portion of the product.

The claimed technical solution eliminates the shortcomings existing today in such solutions, and allows for the production of baskets of combination dispensers that can accurately and accurately dispense sticky and frozen products. 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.
