Description

INGREDIENT DOSES FOR SERIES PRODUCTION LINES FIELD OF THE INVENTION The present invention relates to a dosing equipment of ingredients to be distributed on a product. More specifically it is a dosing equipment of ingredients in pieces, granulated or in powder, in different sizes and shapes that also applies it on the surface of a product.

BACKGROUND OF THE INVENTION Currently there are production lines, where for specific reasons of the process, it is required to deposit a precise amount of ingredients in pieces, granulated or powdered on food products.

The dosificadores of current ingredients, waste a lot of product and are imprecise with respect to the amount that deposit of the ingredient or are too complicated and therefore costly.

Being the industrial bakery a productivity activity of high performance, it is required, first of all, that the unit operations that are required to achieve the manufacture of a given product, are developed with precision and at acceptable speeds.

Other qualities that have been seen are fundamental in the machines of the baking industry, are that the machines also have a certain versatility to work properly even when there is some variation as for, for example, in our case, the size or shape of the product to be spread, without waste of it.

OBJECTIVES OF THE INVENTION The present invention has as its first objective to make available a machine or device for dosing and spraying ingredients into pieces, granules or powders with a suitable precision both in the quantity to be distributed on the surface of some product, and on the surface in which is going to do this sprinkling.

Another objective of the present invention is to have a machine with the qualities listed above, which is also versatile to handle different ingredients with difference both in size and shape as well as in its consistency.

Still another objective is to have this device with the quality of being simple and robust in terms of its mechanical strength in order to have a long service life.

And all those qualities and objectives that will become apparent when making a description of the present invention, supported by the illustrated modalities.

BRIEF DESCRIPTION OF THE INVENTION Broadly speaking, the distributor dispenser of ingredients in piece, granulate or powder of the present invention consists of 1) a feed hopper where the ingredient to be dosed and spread will be loaded, in order to achieve a control of the thickness of the ingredient that we desire, in the base of the hopper is 2) an opening through which will pass the ingredient that will form a continuous layer that will be deposited in 3) a first band, intermediate called rasadora band, where it is leveled the height of the layer of grediente that unloads in 4) a lower band where the layer of the ingredient is distributed leaving empty spaces corresponding to the voids left by the product where the ingredient is going to be deposited.

The ingredient is then fed into the hopper, hopper that is It lies above the level of the other elements of the dispenser, sliding said ingredient to the base of said hopper and through an opening that the hopper has in the base, the ingredient is deposited in the rasadora band. The scraper band, placed directly above the second conveyor belt, transports the continuous layer of ingredient and deposits it on said second conveyor belt.

Normally the product in which the ingredient is going to be deposited (nuts, raisins, granules, sugar balls, among others), is distributed in the lower band on which the dispenser is placed, leaving empty longitudinal and transverse spaces in where, to avoid the waste of the ingredient, this should not be deposited. To do this, between the point where the razing band drops the product and the exit strip, the dispenser comprises a line of angles with the ends of its sides facing downwards, distributed transversely covering the spaces where no ingredient should be deposited, forming in the strip of exit continuous bands corresponding to the rows of product formed in the band of product to spread with the ingredient.

To avoid depositing ingredient in the transverse spaces, the dispenser has a system of photosensitive and light emitting cells that detects the empty spaces of product in the product band and for the dispenser in these spaces.

The parameters of the dosing device that intervenes in the dosage of the ingredient to be deposited in the product are: a) the width of the exit opening of the feeding hopper, the wider this opening is, the more quantity of ingredient is provided, b) the distance between the outer end of said opening and the upper surface of the lower band called the scraping band, the ingredient itself deposited in the scraping band prevents, when it reaches the level of the outlet opening, the exit of more The amount of the ingredient will be provided by the dosing machine and c) the operating speed of the dosing machine, the more separated the upper surface of the scraping belt from the lower end of the outlet opening of the feed hopper.

When all the other parameters are constant, the amount of ingredient to be deposited is controlled by the speed of the dosing machine in an inverse relationship, at a lower speed the amount that is deposited in the product, having as a limit the thickness that the bars allow Appliances included above said scraper band. When the dispenser is at a slow or fully stopped speed, the product deposited directly below the exit opening of the hopper prevents more ingredient from flowing into the belt. On the other hand it is important to mention that the speed of the dispenser is synchronized with the speed of the conveyor belt of the product.

For a better understanding of the attempt will be made to make the description of the modality thereof illustrated in the drawings for illustrative purposes, but not limited to the present description.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 shows an isometric of the ingredient dispenser showing the details of the inside of the feed hopper with a cut in it.

In Figure 2 a side view of the ingredient dispenser illustrated in Figure 1 is shown.

A detailed description of the embodiment illustrated in the figures will be made below, serving the same reference signs to indicate the same parts in the figures shown.

DETAILED DESCRIPTION OF THE PREFERRED MODALITY The elements of the dispenser are mounted on a structure 1, where the main gearmotor 2 will move most of the mobile elements of the dispenser, moving the gearmotor 9 only the output band of the dispenser (7).

Then on the tubular structure 1 are assembled the ingredients reception hopper (3), a dosing conveyor belt (6) and an output conveyor belt (7).

The hopper receives the granulated ingredient and inside it is assembled a cave breaker or clods (5) constituted by an arrow with radially arranged bolts which has rotary movement that fluidizes the ingredient. The broken lumps (5) receives transmission through chains and sprockets of the main gearmotor (2).

The products (A) advance on the conveyor belt (11) of product, until the photoelectric sensor (8) detects the product A on which the ingredient is going to be deposited, at this moment, the photoelectric sensor (8) that is interconnected with the motor-ducts (2) and (9) that give movement to the dosing conveyors, also called scraping band (6) and output (7) make these start up through a speed variator. When the photoelectric sensor (8) stops detecting the product, the conveyors stop moving and stop dispensing ingredients.

The ingredient to be dosed is introduced in a hopper (3) that contains it; At the bottom of the hopper there is an opening through which the ingredient flows with the help of a rompecavernas or lump eliminator (5). At the base of the hopper is the metering conveyor (6) that receives the ingredient from the hopper and because the speed of the belt is constant, a uniform layer is formed in the thickness of the ingredient.

"On the band of the dosing conveyor (6) there is a rasadora bar (4), whose function is to uniformize even more the thickness of the layer of ingredient. This rasadora bar (4) has movement of rotation with what is avoided that the ingredient is mistreated.

The rotational movement is imparted by the main gearmotor (2) through a mechanical transmission of sprockets and roller chains. After the dosing conveyor (6), the conveyor d3 outlet (7) is at a lower level, which has the function of forming, with the help of triangular guides (10), carrots of the ingredient, which must be aligned with the product (A) to which the ingredient will be applied.

The photoelectric sensor (8) when detecting product on the product conveyor (11) starts the main gearmotors (2) and the output conveyor (7) starting dosing.

When the photoelectric sensor stops detecting product, the conveyors stop their movement, stopping the dosing of ingredients, avoiding the waste of the ingredient.

The stop and start of the equipment is carried out, as already mentioned, the photoelectric sensor (8) and is complemented by a frequency variator, so that the dosage of the ingredient can be perfectly controlled by keeping the speed of the dosing conveyor controlled (6) .

The movement of the ingredient towards the bottom of the hopper is mostly done only by gravity and only a small boost is due to the rotation of the clod breakers, whose main function is to fluidize the ingredient and allow it to descend freely.

Other embodiments of the invention will be apparent to those skilled in the art, from a consideration of the description or practice of the invention disclosed herein. It is understood that the description and examples are considered only as illustrative, the true scope and spirit of the invention being indicated by the following claims.
