Description

DESCRIPTION

Automatic divider machine for bakery. Object of the invention

The present specification refers to an application for an Invention Patent, relating to an automatic dividing machine for bakery, which has the purpose of dividing a block of dough contained in a hopper into multiple portions of volume equal to that preselected by the user , being able to change said volume according to the needs of the production. Field of the Invention

The invention falls within the technical sector of industrial baking, more specifically in the field of bread dough dividers and related products. Background of the invention

At present, within the technical sector of baking, more specifically in the field of bread dough dividers and related products, we find systems based on the suction, impulsion and sectioning of the dough by means of a plunger and an incisive edge or blade

In patent document ES2005868, a bread dough divider machine is proposed, comprising a oscillating drum, a connecting rod connected at its top by an articulation to a plunger and at its bottom to a transverse arm carrying two droppers run on a rail forcing the plunger path, while allowing

SUBSTITUTE SHEET (RULE 26) regulate its route, getting an alternative movement. This machine presents the problem of a lack of reliability in intensive industrial processes, because the mechanism is subjected to great efforts to rotate the oscillating drum carrying the plunger responsible for sucking and driving the dough, with the edge of the drum being in charge of separating the mass, together with the tension and the tears that it causes, because the stroke always has to be greater than what is really necessary, forcing the mass to pass through a restricted exit hole at high speed, being all this necessary to be able to assure the requested volume.

Patent document DE0334319 deals with a bread dough divider machine, which contains a single or multiple cavity that houses one or several plungers of rectangular section, which are responsible for sucking and driving the dough, being sectioned and separated from the hopper by a distributor distributor. This system has the disadvantage that in order to ensure the requested volume by filling the cavities, it is inevitable that the dough is folded and in turn compressed when it is introduced into the cavity or cavities during the act of suction and discharge before being separated of the mass contained in the hopper, this force or thrust exerted on the folded mass creates a tension effect that will subsequently reverberate on the dough molding. During the process of suction, impulsion, compression, sectioning and expulsion, the mass is forced undergoing tears that will repel

SUBSTITUTE SHEET (RULE 26) negatively in the quality of the finished product. Another disadvantage of this type of dividing machine is that it needs a lubricating oil film between the plunger and the cavity to be able to suck the dough since this type of dividers work without seals / all this has a great oil consumption which is dragged along with the portions of processed dough. These dividers due to their system require periodic maintenance and cleaning. Its reliability is compromised in intensive industrial use due to the great effort to which its mechanical components composed of long connecting rods and levers are subjected. There are other patents based on these principles in which some changes have been made, but in essence they continue to maintain the same basic concept. Detailed description of the invention

The invention that we propose presents a series of advantages over previous patents, presenting as an object a bread dough divider machine which allows its original properties to remain intact during the process of dividing the dough without causing tensions or tears, due to The dough is sectioned incisively and at no time is bent and compressed, allowing its subsequent molding to be done with great ease and perfection. Another important factor is that there is no significant increase in the temperature of the dough, due to the large volume displaced in relation to the short travel and low speed of the

SUBSTITUTE SHEET (RULE 26) few moving parts that make up the mechanism that displaces the mass, the friction between these pieces being minimal. Its compact design allows the machine to be free of mechanical overexertion, offering great flability that allows it to work in the bakery industry intensively. The dividing machine can process any type of dough no matter how hard or soft it is and however high its protein content is so necessary for the bread that it will undergo a deep-freezing process. en masse or precooked and deep-frozen, this being an industrial process increasingly used. The dividing machine has an internal closed circuit lubrication circuit that prevents the lubricating oil from mixing with the dough, therefore its consumption is minimal.

The invention described herein consists of a hopper where the dough is deposited, this hopper is located on a set-extractor, composed of two symmetrical blocks inside which is housed a rotating drum provided with piston-moving blades radially and angularly, guided by two symmetrical guide grooves, sectioning and driving the hopper mass through a volumetric channel, it also has a deflector that deflects the mass preventing it from returning to the hopper again, introducing it into another volumetric set consisting of elements common to the extractor set also having a volumetric channel where the mass volume shifts

SUBSTITUTE SHEET (RULE 26) requested to then go through another evacuation channel, where the mass that has been previously sectioned by the plunger blades is joined, said evacuation channel being divided into two parts, its upper part being removable for better cleaning; At the end of the evacuation channel we find the evacuation hole in whose lower part a knife-portioning assembly is provided with a knife-portioner that travels at high speed in a reciprocating movement, integral to a linear guidance system , responsible for dividing the dough into portions according to the volume required.

The extractor set disposed on the upper entrance of the volumetric assembly has a torque-motor control for a better control of the force or thrust exerted on the mass between the extractor set and the volumetric assembly helping this form so that the mass is introduced in said volumetric assembly filling all the empty spaces without contributing to the mass unnecessary tensions, because the mass is not bent at any time of its route, also having a probe for the extraction of the gases produced by processing the previously fermented dough, or by the air contained in it, this probe has a socket capable of being connected to a vacuum generating system. This probe is strategically located at the point of accumulation of said gases located within the radius of the deflector of said assembly.

SUBSTITUTE SHEET (RULE 26) The volumetric assembly has an angular positioning control that allows the required mass volume to be displaced with absolute precision, being subsequently divided into portions by the knife-portioning assembly, electronically controlled so that it acts perfectly synchronized with the displacement of the mass performing start-stop stations.

The set-extractor is tiltable, being connected to the set-volumetric by means of a base plate equipped with a hinge and a closing system by means of pneumatically operated latches, having a safety system by interlocking with compression spring that prevents opening accidental during the division process if the compressed air supply fails. This tilting allows a better cleaning of the mass remains inside the mechanisms.

From the observation of the figures outlined it follows that an example of practical realization has been chosen in which:

In figures 3 and 4 we can see how the machine is fed by the mass contained in a hopper 1 located in the upper part of the extractor assembly comprising the following parts: The right blocks

3 and left 4 that symmetrically joined by means of cylindrical pins 5 form in their upper part a mass inlet 6 which is communicated with the lower mouth 2 of the hopper 1 and in turn with the volumetric channel 7 where the mass is sectioned and displaced by the piston-blades 8 shown in the figure

4 we can see how they pass inside radial-recesses 9 made in a rotating drum 10 being arranged in a polar and equidistant way, preferably five arranged at 72 angular degrees, this being a preferential and not determining condition for its correct operation, the blades -embol 8 inside the recesses-

SUBSTITUTE SHEET (RULE 26) Radial 9 follow a path marked by right and left guide grooves 11 that are symmetrical as we see in Figures 7 and 8, inside which guide bearings 13 integral to the lower ends of the blades-plunger 8 pass according to It can be seen in Figure 6, the mass being susceptible to being displaced through the volumetric channel 7, in turn creating a suction effect on the mass contained in the hopper 1, said mass moving in a clockwise direction as shown in Figure 4 in the direction towards the deflector 14, according to figures 12 and 4 arranged very tightly on the rolling face of the rotating-drum 10 taking off and gradually deflecting the mass towards the outlet 15 and avoiding at the same time that it can be reintroduced into the hopper 1, in figures 3 and 4 we can see how the rotating drum 10 is located in the cavity formed by the union of the blocks 3 and 4, being positioned so concentric with respect to the volumetric channel 7, having drum-rotating rings 16 which provide greater rigidity to the rotating-drum 10, these being in turn provided with two radial retainers 17, with a support shaft 18 and a drive axle 19 arranged on bearings-support-axle 20, said shafts 18 and 19 are provided with radial shaft seals 21 being located inside axle covers 22 tied to the side faces of the right blocks 3 e left 4, the plunger blades 8 have linear seals 23

SUBSTITUTE SHEET (RULE 26) which are embedded between the rotating drum 10 and the rotating drum rings 16, we can see said linear seals 23 in figures 3, 6, 23 and 24 whose function is to prevent the entry of mass into the interior of the radial cutouts 9 and the outlet of the lubricating oil contained in said radial cutouts 9; in figures 5 and 6 we can see that at the lower ends of the plunger blades 8 are arranged blade-plunger guides 24 which slide through guide grooves 25 practiced on each side of the rotating drum 10 to achieve a perfect lateral guidance, as can be seen in Figure 4, the plunger blades 8 at the moment in which they propel and section the mass contained in the hopper 1, emerge from the rotating drum 10 in its total useful length (understanding by useful length the area of the plunger-blades 8 that is in contact with the mass), and on the contrary when they pass through the point where the deflector 14 is located, they are fully inserted into the rotating drum 10, counting in turn with various intermediate positions inside the radial recesses 9 during its trajectory, being determined by the symmetrical guide grooves 11 and 12. The drive shaft 19 of the rotating drum 10 of the set-ex tractor has a drive with torque control, which supplies very precisely the force or thrust to be exerted by the piston-blades 8 on the mass that is introduced into the volumetric assembly through the input 28, this comprising volumetric set of

SUBSTITUTE SHEET (RULE 26) following parts: as can be seen in Figure 3, we see the right block 26 which, together with the left block 27, symmetrically forms an entrance 28 of the mass that comes from the outlet 15 of the extractor assembly, as it can be see in figure 4, filling all the empty spaces that are generated between each two consecutive blades-piston 8 during its angular advance, the two blades-piston 8 being outside the rotating drum 10 in its entire useful length, sectioning and driving In the counterclockwise mass as shown in Figure 4, these plunger blades 8 according to Figures 9 and 10 follow a path within the radial-recesses 9 marked by right and left guide grooves 30 that are symmetrical at the same time that these plunger blades 8 rotate in solidarity with the rotating drum 10 with a perfect angular positioning in each feed, equivalent to the volume of mass previously selected, this angular positioning is provided by the drive shaft 19 which is governed by an electronic control by means of a computer program, in Figure 4 we can see how this mass is sectioned and driven counterclockwise through the volumetric channel 31 to a deflector 32 which we can see in figures 4 and 13 responsible for progressively diverting the mass towards the evacuation channel 33 at which time the plunger blades 8 are fully inserted in the rotating drum 10 which is located in the cavity formed by the joint of blocks 26 and 27, being

SUBSTITUTE SHEET (RULE 26) placed concentrically with respect to the volumetric channel 31 / in the evacuation channel 33 the mass that has previously been sectioned by the blades-plunger 8 is rejoined because said evacuation channel 33 has an irregular shape but without presenting reduction some in its section, whereby the passage of the mass through the evacuation channel 33 is not restricted at any point, which we can see in figure 25, its upper part 34 being removable for better cleaning according to figure 2 , continuing ^'its trajectory toward the discharge port 35, the remainder of the components forming the common to the above in the description set-extractor as seen in figure 3 set-volume.

Next we refer to the parts that comprise the knife-portioning assembly; As shown in Figure 11, the cutter-blade 36 in charge of dividing the displaced mass in portions through the evacuation hole 35 according to the previously selected volume, since this mass is part of a continuous block before being sectioned / the cutting-blade 36 is attached to a knife-portioning support 37, to which guide-skates 38 are moored that slide on linear guides 39 tied to the right 26 and left 27 blocks of the volumetric assembly parallel to the inclined front face 97, in front of the support of the knife-portioner 37 is

SUBSTITUTE SHEET (RULE 26) a gasket-cover 40 is disposed between the frame of the machine and said support of the knife-portioner 37 and at the bottom of said support of the knife-portioner 37 a connecting flange 41 to which it is attached to a connecting rod 42 by means of an articulated shaft 43, the connecting rod 42 is in turn connected to a crank 44 by means of an articulated shaft 45, said crank 44 is tied to the axis of a planetary reducer 46, which in turn is tied to a support of the blade-portioning assembly 47, which is fixed at its top to the base of the right 26 and left 27 blocks of the volumetric assembly / planetary reducer 46 is operated by a servomotor 48 commanded by an electronic control perfectly synchronized with the control of the volumetric assembly, so that when the mass is driven by the volumetric assembly, the portioning knife 36 must leave the evacuation hole 35 free, while waiting for the volumetric assembly or move the next mass volume again and stop, immediately acting on the knife-portioning assembly by cutting the mass, leaving a waiting time until the volumetric assembly returns to move the next mass volume; This waiting time will depend on the programmed cadence.

In solidarity with the extractor assembly is the closure assembly comprising the following parts as shown in Figures 2, 14, 15, 16 and 17; the base plate 49 susceptible to tilting, on whose top the extractor assembly is attached, which
