Definitions

  • the present invention relates to a cutting device automated sliced breads.
  • Automated cutting devices for breads Slices are well known. We meet them in most craft bakeries and also in supermarkets. These devices, or automatic bread slicers, operate according to the following principle: The user of the device introduces the bread he wants cut into slices by placing it in a compartment arranged between a drive element of the bread and a set of parallel blades slicing said bread. The user then puts the device into by switching on the switch provided for this purpose, which leads to alternating movement of the blades and in translation movement transversely to the direction of the blades of the drive element of the bread. The bread is therefore displaced by this training element in direction of the blades and cutting begins when it comes in contact with these. The user recovers his sliced bread in a compartment arranged on the side of the blades opposite to that where is arranged the bread loading compartment in the device. He ... not this user is left more than to pack the cut bread.
  • the quality of the bread cut will be poor because the slices will have a crushed appearance on the side of their leading edge by the blades as well as rips of their crumb. II the same with a bread with a hard crust and a crumb soft because in this case, too high engine power and therefore a excessive speed of the element of training bread at the beginning cutting will also cause excessive pressure on the crust during his attack by the blades and therefore a breaking of the crust against the blades and a subsequent crumbling of the latter, followed by a tearing of the crumb as explained above during cutting.
  • the present invention solves the aforementioned problems and overcomes the disadvantages associated with it by proposing a device automated cutting of sliced breads in which the speed of the training element of the bread is automatically adapted to type of bread to cut and especially to the hardness of its crust and the firmness of its crumb, and this throughout the cutting operation.
  • the invention consists of a cutting device automated slice of bread with an element training bread arranged to be moved by means of a means displacement coupled to said element between a first position of recess in which the carving bread can be loaded into the device and a second advancement position in which the cut bread can be removed from the device, the device further comprising a set bread cutting blades arranged substantially parallel to the to each other and arranged to be animated by a movement alternating back and forth, the training element of the bread being arranged for, when the device is in operation, drive the bread into a translation movement to and through the blade assembly between the first and the second position of said element, the device further comprising means arranged to automatically regulate the power supplied by the engine according to the speed and / or the acceleration of the translational movement of the drive element bread during the cutting operation thereof.
  • the cutting of a bread is always optimized according to the type of bread in question. Indeed, when the bread opposes an important resistance to the blades at the beginning of cutting, ie when the crust of the bread is hard, the speed of displacement of the training element will be quickly and strongly reduced and this strong and fast deceleration will be spotted by means of regulation that will decrease the power provided by the means of movement of the training element and the crust will be cut without breaking it by crushing the bread on the blades due to excessive speed and / or acceleration of moving the drive element of the bread.
  • the device 1 comprises a chassis 2 comprising a cutting table 3 of a bread 4 that is available in a loading compartment 5 of the device.
  • This one still includes a drive element 7 of the bread 4 and a set of blades 8 disposed substantially parallel to each other and arranged to be animated by an alternating back and forth movement for cut the bread 4 into slices.
  • a bread press 6 is also provided, consisting of a blade exerting a pressure on the top of the bread for avoid his thrill during the cutting operation the blade assembly 8 opposite the load compartment 5 of the bread 4 is provided a compartment 9 for unloading bread 4 cut into slices.
  • the training element 7 of the bread 4 is arranged to be moved in a translational motion parallel to the table of cut 3 and transversely to the set of blades 8 between a first recoil position in which a bread 4 can be introduced into the loading compartment 5 and a second advancement position wherein the training element 7 of the bread is adjacent to the set of blades 8 and the bread 4 cut into slices and disposed in the unloading compartment 9 can be removed from device 1.
  • the movement of the training element 7 is effected by means of a electric motor 10 comprising a rotor and a stator, coupled to said driving element 7 by a jack 11 actuating an articulated arm 12 comprising a first element 12a articulated by a hinge or a ball joint to a second element 12b, a first end of the arm 12 pivotable about a pivot 13 and a second end of said arm 12 being connected to the training element 7.
  • the power provided by the motor 10 coupled to the element 7 of the bread 4 during the operation of the device 1 is automatically regulated by a regulating means 14 as a function of the speed of said driving element 7, which is conditioned by the resistance that the bread 4 and the bread press 6 oppose to the whole blades 8 during the cutting operation of said bread. Indeed, the press bread 6 by exerting pressure on said bread 4 increases the resistance that it opposes by itself to the set of blades 8.
  • the means of regulator 14 is arranged to measure the rotational speed of the rotor in the stator of the motor 10 to determine the speed of the movement of translation of the training element 7 of the bread 4 and is also arranged to compare the measured speed to a predetermined speed and to increase or decrease the power of the motor 10 when this measured speed is respectively lower or higher than the speed predetermined.
  • the speed of movement of the training element 7 itself which can be directly measured by means of regulation 14, for example by means of position sensors such as photocells arranged on the path of the element Training 7.
  • the speed of this cutting is permanently optimized by the device according to the invention.
  • a bread with hard crust or on the contrary very flexible cut into the device according to the invention and that the crust reaches the blade assembly 8 a very important resistance to the movement of translation of the drive element 7 of the bread is opposed by the crust cut by the blade assembly 8, either because of the hardness of said crust or compression of soft crust bread.
  • Even in the case of bread of another type, such resistance may to be provoked, mainly then by the pressure exerted by the press bread on said bread.
  • This resistance causes a peak of intensity of the current consumed by the motor 10 which indicates that the power of this motor and therefore the current consumed must be reduced to prevent the crust of the bread is crushed against the blades because of excessive pressure exerted by the training element 7 on the bread.
  • This Peak intensity corresponds to a predetermined value and can be measured and the current well so that the power of the motor 10 can in response to be strongly reduced to another predetermined value so that the crust of the bread is cut so optimal without crushing. That is why the means of regulation of the device 1 according to the invention is also arranged to reduce the intensity of the current consumed by the engine 10 to a first predetermined value when this intensity exceeds a second value predetermined.
  • the aforementioned peak of intensity is replaced by a peak of air pressure used to move the drive element 7.
  • the regulated power is also in this case the air pressure in question.
  • the set of blades 8 attacks the cutting of the crumb of bread 4. If the speed of movement of the training element 7 and therefore of cutting of the bread 4 is then less than a predetermined value, the regulating means 14 will increase the power of the motor 10 to this value is reached, so as to prevent a speed too much slow operation will lead to excessive friction of the blade assembly 8 breadcrumb 4 and the subsequent appearance of a pilling of this mie. If, for example, in the case of a very light bread, the predetermined value of the cutting speed of the bread was exceeded, the regulating means 14 would control a decrease in power motor 10 to prevent cracks in the crumb due to speed or at an acceleration of displacement of the training element 7 excessive.
  • the regulating means 14 is furthermore arranged to provoke a reversal of the direction of movement of the driving element 7 of the bread 4 when it reaches its first or second position.
  • This inversion can be provoked in many ways It can be controlled by at least one photocell (not shown) arranged to locate the arrival of the training element 7 in its first or second position or alternatively by providing that the control means 14 is arranged to measure the number of turns performed by the rotor of the motor 10 in its stator and to provoke said inversion from one of the first or second positions of the driving element 7 when said number of turns reaches a predetermined value from the other of the first or second positions of the training element 7.
  • the inversion in question may be provoked one of the first or second positions of the training element 7 when the intensity of the current consumed by the motor 10 exceeds a predetermined threshold value occurring during the abutment of the element 7 against a stop at the level of its first and / or second positions.
  • the regulating means 14 may comprise a control circuit of the power supplied by the controlled motor 10 by an electronic chip programmed for, from a measurement by an ammeter of the intensity of the current consumed by the motor 10 and the number of revolutions per unit time of the rotor of said motor 10 in its stator, indicated for example by means of a coupled counting disc rotor audit, calculate the speed and / or acceleration of the element 7 and control the power control circuit above.
  • the regulating means 14 is connected to the motor 10 by a first electrical cable 15 transmitting the intensity information of current and motor speed mentioned above and a second electric cable 16 supplying the motor 10 with electricity.
