PROCESS FOR SPREADING PASTE STRIPS AND SPREADING DEVICE FOR UNITS FOR PRODUCING BAKERY PRODUCTS, VIENNOISERIES AND THE LIKE.

FR 3,061,634 - A1 tbq) The present invention relates to a method for spreading strips of dough (2, 3), resulting from a longitudinal cutting into strips of a strip of laminated dough (4), and moving on an upstream conveyor belt (4) characterized in that one diverts a strip of dough (2) out of two on a first downstream conveyor belt (7) extending on a higher level compared to a second conveyor belt downstream transport (8) extending to a lower level, said second belt (8) taking care of the other dough strips (3) not supported by said first downstream transport belt (7).

The invention also relates to a spreader device (1) for spreading dough strips (2, 3).

ι

The present invention relates to units for the production of bakery products, pastries and the like and relates, in particular, to units for processing the dough at the end of kneading for the manufacture of baguettes, long breads, elongated buns.

In particular, it is known to supply dough, through a kneading machine, a rolling unit which, in its downstream part, comes on a suitable conveyor belt, a strip of dough of constant thickness and width adapted to that of said conveyor belt.

This strip of dough is cut longitudinally into strips of regular width, which are separated from each other by a suitable spacer device.

Note that such a spacing of a sufficient distance from the dough strips is essential to prevent them from sticking together during the final fermentation and / or during their passage through the oven to ensure homogeneous cooking of the products. , especially at their contiguous flanks.

It should also be noted that the strips of dough are themselves cut into sections of length adapted to the size of the baguettes, long breads or elongated buns that one wishes to obtain.

These dough sections can then undergo a shaping operation before being deposited on fermentation and / or cooking supports.

The problem posed by this prior solution lies precisely in this spacer device.

In particular, said spacer device consists of a plurality of divergent belts or belts which lead precisely to the spacing of the strips of dough.

Downstream of this spreader device, these dough strips extend substantially with regular spacing on a conveyor belt which has a width approximately twice the width of the conveyor belt upstream of the spreader device.

In more detail, the two most common types of spacer devices are:

1) The system with divergent belts:

This system includes belts stretched between two splined axes, one of which is motor.

- the entry axis is generally half the width of the exit axis and its number of grooves corresponds to the total number of belts,

- the exit axis, twice as wide, has the same grooves as the entry axis but in number twice as large, and the operator chooses to group the belts in twos or threes depending lengths of strips to transport and spread between them.

This system with multiple belts presents risks of roughing up in the event of a significant angle of divergence and also of pinching of the dough between the grouped belts to collectively support the strips, with the consequences of tearing off the dough and fouling.

2) The divergent carpet system:

This system does not have any of these drawbacks, but it is not at all flexible and a set of divergent mats is required per type of product to be discarded, the number of divergent mats and their width must imperatively correspond to the number of strips of dough cut upstream and to their length.

This system, in addition to its cost, leads to prolonged production stoppages with each change of product format.

It appears that these spacer devices, as described above, are heavy and unreliable.

Furthermore, whatever the quality and the care taken in the longitudinal cutting of the strip of dough into strips, these tend, at times, to remain stuck together, even partially, resulting in an uncontrolled progression on the spreader device and a somewhat random arrangement on the downstream conveyor belt.

In particular when some of these strips of dough do not extend parallel to one another, the shaping of the sections of dough, after cutting the strips to the desired length according to the products to be produced, cannot be done in good conditions. Above all, this can alter the deposit of these sections of dough on the support plates for their fermentation and / or cooking.

The object of the present invention is to provide a new device which makes it possible to provide, in a more simple and effective manner, a spacing between the strips of dough resulting from the longitudinal cutting of a strip of laminated dough.

It is in the context of an inventive approach that we imagined ensuring a differentiated path for one strip of dough out of two.

It was within the framework of a second inventive step that one thought to deflect one strip of dough out of two on a first conveyor belt extending on a higher level compared to a second conveyor belt extending to a lower level, said second conveyor taking care of the other strips of dough not supported by said first conveyor belt.

The present invention therefore relates to a method for spreading strips of dough, resulting from a longitudinal cutting into strips of a strip of laminated dough, and moving on an upstream conveyor belt characterized in that one deviates a strip of dough out of two on a first downstream conveyor belt extending on a higher level with respect to a second downstream conveyor belt extending at a lower level, said second mat taking care of the other strips of dough not taken in loaded by said first downstream conveyor belt.

The present invention also relates to a spacer device for separating strips of dough from a longitudinal cutting into strips of a strip of laminated dough and moving on an upstream conveyor belt characterized in that it comprises, in the extension of the upstream belt, at least two downstream belts located respectively, one relative to the other, vertically in two planes of different levels.

It appears from the above, that the invention consists in replacing the spacer belts previously described by a device which creates 1 ¹ spacing between the strips by their evacuation, from their longitudinal cutting, on two separate levels, one ensuring the evacuation of the so-called “even” strips, the other the evacuation of the so-called “odd” strips, it being understood that one thus creates two separate ways of evacuation of the strips of dough, without the need to do call for any divergence equipment.

The method and the device of the invention thus make it possible to route the separated strips in two separate ways to two separate cutting and shaping stations before they are deposited on the fermentation and / or cooking supports.

The advantage of such an evacuation on two separate levels is particularly decisive for very large industrial hourly productions, which in any case require the duplication of the cutting and shaping operations of the strips and their removal after their shaping on the supports. fermentation and / or cooking.

Other objects and advantages of the present invention will emerge during the description which follows, relating to an exemplary embodiment given by way of non-limiting indication.

The understanding of this description will be facilitated by referring to the attached drawings in which:

- Figure 1 is a schematic representation, and in longitudinal section, of a first particular embodiment of a spacer device according to the present invention;

- Figure 2 is a schematic representation similar to Figure 1, where the spacer device of the invention is seen from above;

- Figure 3 is a schematic representation, and in longitudinal section, of a second particular embodiment of a spacer device according to the present invention.

As shown diagrammatically in the figures of the attached drawings, the present invention relates to a spacer device 1 and to a method for spreading strips of dough 2,

3.

In particular, the device 1 of the invention is intended to be integrated into units for the production of bakery products, pastries and the like and, more particularly still, to units for processing the dough at the kneading outlet for the purpose of make, as appropriate, baguettes, long breads or even elongated buns.

The strips of dough 2, 3 which must undergo the spacing operation come from a longitudinal cutting of a strip of laminated dough 4, shown by means of horizontal lines in the attached figures.

Thus, according to the rolling operation, the rolled dough strip 4 is conveyed on an upstream conveyor belt 5 to a means for longitudinally cutting said dough strip 4 into strips of pasta 2, 3 constituted for example by a disc cutter 6. The conveying direction of the dough is shown in Figure 1 by means of an arrow.

In a particularly advantageous manner, in the process of the invention, according to the step of longitudinal cutting of the strip of dough 4 into strips of dough 2, 3, one strip of dough 2 out of two is deflected on a first downstream conveyor belt 7 extending on a higher level with respect to a second downstream conveyor belt 8 extending at a lower level, said second belt 8 ensuring the taking over of the other strips of dough 3 not taken care of by said first conveyor belt downstream transport 7.

In other words, the separation of the dough strips 2, 3 which are in contiguous, after slitting is to evacuate said strips on two conveyor belts downstream 7, 8 which form two superposed levels ¹ separate evacuation.

In the embodiments illustrated in FIGS. 1 to 3 attached, the dough strips 2 are represented by dotted lines and are taken care of once the longitudinal cutting has been carried out by a downstream conveyor belt 7 situated at a higher level relative to to the lower downstream conveyor belt 8, which allows the evacuation of the hatched dough strips 3.

The operation of deflecting one strip of dough out of two can be done by any suitable means, in particular by manual action on the part of an operator.

The present invention also relates to a spacer device 1 suitable for implementing the method described above, said spacer device 1 comprising at least, in the extension of an upstream conveyor belt 5 conveying a strip of laminated dough 4 , two downstream conveyor belts 7, 8 located respectively, one relative to the other vertically in two planes of different levels.

The method and the device 1 of the invention allow, for example, at the outlet of an initial dough strip 4 with a width of 1.25 m consisting, for example, of 28 adjoining strips of approximately 4.5 cm in width, to separate them into two lanes of fourteen strips over a belt width of 1.25 m, all twenty-eight strips being evacuated by sets of downstream conveyor belts 7, 8 straight or curved towards two separate sets and autonomous:

- transverse cutting,

- shaping,

- various fillings,

- removal on supports.

In this case, this system makes it possible to automatically fill, in the example chosen, plates or supports 1.25 m wide and in this case, each downstream conveyor belt 7, 8 garnishes a complete plate in one go .

In another example, supports 2.5 m wide can be fitted, each of the downstream conveyor belts 7, 8 ensuring the deposition of the products on one half of the support, the conveying of said support ensuring its passage under each of the removal of each of said downstream conveyor belts 7, 8.

The device 1 of the invention has the advantage of effecting effective separation of the strips 2, 3 between them, even in the case of very hydrated and very sticky pastes, because:

- separation by 1'orientation of the strips 2, 3 at a rate of one in two, on two different levels, can be done almost as soon as cutting by the disc cutter 6, that is to say before the strips 2, 3 have had time to reweave (which is not the case with divergent carpets where separation is slow and gradual).

- The separation is straightforward because the raising of one strip out of two, or the descent of one strip with respect to keeping the other in line, constitutes a shearing effect, which is effective for taking off the strips.

- The device 1 saves space compared to the spacer systems by belts or by carpet.

the device 1 is particularly suitable for very high hourly productions for which it is necessary to split the shaping, shaping and depositing machines and which operate with very large support plates, in order to reduce the handling rates of said supports .

Such supports can largely exceed a width of 2 m and filling them in half from two separate supply routes constitutes an industrial process.
