With reference to the accompanying drawings, most preferred embodiment of the present invention is described by way of example, wherein:
Fig. 1 is a total schematic side diagrammatic sketch, shows one of them embodiment of present device.
Fig. 2 is a schematic diagram, has explained the forming process of each section that cuts into spheroid.
Fig. 3 and 4 shows the cutter that has three and six compressive surface respectively.
Fig. 5 and Fig. 6 are schematic diagrames, have explained the cutting function of the cutter with thick compressive surface according to the present invention.
, explain method of the present invention now by with reference to accompanying drawing and based on one of them embodiment of present device.
In Fig. 1, an extensor 2 extends into a sheets of bread dough 3 with constant width and thickness continuously with the bread dough 1 of a feeding on conveyer 21.Can adopt any traditional extensor, disclosed a kind of in 107 such as United States Patent (USP) 4,692, as extensor.
Dough sheet 3 after one roll-up device 4 will extend is rolled into a continuous strip dough 5.Roll-up device 4 is rolled dough sheet from one of them edge of dough sheet along the direction that favours its width.It has a band discaling roll along the rotation of direction shown in the arrow, to roll dough sheet.Can adopt any traditional side roll-up device, disclosed the sort of such as above-mentioned open text, as roll-up device 4.One is positioned near the conveyer 21 and the conveyers 8 of weighing in downstream detect the weight of all parts of the continuous strip dough 5 of downstream transport continuously.These weight deposit controller 7 in the information of the position of all parts of strip dough of being weighed on the conveyer 8 of weighing.Detect these weight by detect the distance that the strip doughs move on the conveyer 8 of weighing by means of a rotary encoder or a rotary converter 6.
The downstream that one cutter 9 is positioned at the conveyer 8 of weighing with and the upper surface below.The continuous strip dough 5 that falls from conveyer 8 downstream of weighing based on the information cutter cuts of sending here by controller 7 and moulding.That is to say based on the weight of detected continuous strip dough 5 or the information of length and cut.Because this scheme, can freely produce the strip bread of any kind of, scope from the French toast of elongated shape (50-60mm is wide, and about 1m grows) to cob loaf.
Now explain cutting operation in more detail by controller 7 controls.
In first method of simplifying, the standard weights of a product to be produced " a " is inserted controller 7 in advance.On conveyer, produce also feeding dough sheet 3 in all one's life then and it is rolled into a strip dough 5.The strip dough is sent to the conveyer 8 of weighing that has weighing device 81.Detect strip dough 5(and hereinafter be referred to as the part of dough body) the weight A of given unit length (can be 3mm even shorter).Detected value with obtain by detector 6 and deposited in controller 7 from the out of Memory of its input, these out of Memory can be the distances of moving on the conveyer 8 of weighing as dough body in the given time.The weight A of the dough body each several part that is obtained by detector 6 by adding up, controller 7 calculates a length X of strip dough to be cut, total like this weight weight " a " that just is near the mark.Based on the value that calculates, controller 7 is sent a signal to cutter 9, and during the proper range ability X in the position of cutting from last time on dough is being weighed conveyer, the strip dough is cut like this.Behind each cutting strip dough, detector 6 is refitted in zero, so that repeat identical weighing, calculate, and cutting process.
Select as a kind of convenience but not too accurately, particularly when feeding one width and the uniform dough sheet of thickness, length X can be easily calculated by following equation: X=L * a/A, wherein can be longer than X with the foregoing description Different L, and can be the whole length of upper run of conveyer 8 of weighing; A is that length is the weight of the dough body of L; A is a standard weights.Based on the value of calculating with above-mentioned formula, the preset point position (cutting herein) of the strip dough of conveying can deposit controller 7 on the conveyer 8 of weighing, and controller 7 can be sent and cut the strip dough when signal arrives cutter 9 with this position of box lunch like this.
In arbitrary embodiment, in the starting point of operation, can carry out once virtual cutting, to set up the starting point that controller detects.
From the above description as can be known, the weight of product 11 or length are by determining the opportunity that it is cut.With regard to French toast, important as the length of fruit product, just detect the range ability of strip dough but not weight, and based on the product that just can similar cutting strip dough about the information of distance has predetermined length with production.
And the amount of the product of being produced also can change, simultaneously by increasing or reduce the speed of conveyer or can making one to be kept even by the standard weights of slitting shape bread by the volume of the dough of dough feedway supplys.Can not carry out this adjustment simultaneously when finding scheduled volume and actual detected value to be produced.When find to have any not simultaneously, controller 7 is sent a signal to improve or to reduce the speed of dough sheet feeding, remedies difference like this.So the present invention can make production control more easy.
Referring again to Fig. 1, one second conveyer 10 of weighing also can be positioned at cutter 9 belows and connect one in its downstream and discharges conveyer 22.The second conveyer weight of the strip-shaped surface agglomerate 11 that downcuts of weighing again of weighing, the weight of the piece of being cut to determine whether meets standard weights.If do not meet, controller 7 is just regulated the time of the speed of feeding dough.
As shown in Figure 2, an embodiment of the present invention's cutter 9 has two flat compressive surface 20.They are different from the conventional blades that is shaped to wedge-like.It is thick that compressive surface 20 preferably is at least 30mm, especially when their cutting French toast.The quilt place of the cutting section of strip dough 5 is just very level and smooth and be round like this.This be because when compressive surface 20 is tangentially slided with respect to the periphery of strip dough 5 in the effect of the tangential stress of the contact area generation of strip dough.
One tentative example shows that when adopting thin compressive surface 20 cutting section of formation is the same more coarse with the sharp-pointed cutting member of employing tradition, rather than above-mentioned circular surface.Like this, if the thickness of compressive surface less than certain limit, such as 25-30mm, effect is just bad during cutting, French toast is particularly like this, cutting section is a circular surface not really smoothly and not just like this.
Yet according to the viscosity of strip dough, thickness can be less than 25mm.In the cutter 9 that has compressive surface shown in Figure 2, the center towards continuous strip dough 5 is pressed on its circumference two compressive surface 20 from both direction, and simultaneously they are in parallel to each other but move on the contrary.In Fig. 2, the direction vector of the extruding force that the periphery of 20 pairs of strip doughs 5 of compressive surface of arrow " a " and " b " expression cutter 9 produces.Arrow " c " expression is by the direction of the combined vectors of two vectors generations.This combined vectors, or torsion also help dough sheet layer stacked in rolling step bonding mutually.By along the tissue orientation that circumferentially makes bread dough, this torsion also can produce good effect to the moulding of bread dough.
Arrow among Fig. 5 " d " expression is the traffic direction of the strip dough 5 of supply continuously.Along with it by feeding so continuously, respectively as arrow among Fig. 6 " e " and " e ' " shown in, compressive surface 20 conform to strip dough feed speed upper and lower motion, to avoid the hysteresis in the cutting operation.They are separated from each other to allow strip dough 5 by between them when compressive surface 20 moves upward, and they are approaching mutually with extruding strip dough when they move down.
Fig. 3 and 4 shows other embodiment of cutter of the present invention.Fig. 3 and 4 has three and six compressive surface respectively.United States Patent (USP) 4,734,024 and 5,098,273 disclosed any these cutters all can be used to cut strip dough 5.
As mentioned above, by adopting a kind of simple method and a kind of equipment simple in structure, but the bar shaped bread of production various sizes is reducing to have very big industrial effect on the production cost.
