- Figures 4 to 7 show a part of the shaper of Figure 2 during different phases of the ejection of a double dough piece.
- the dough shaping machine designated by the general reference 10, comprises a frame 12, produced for example from beams and metal profiles, on which one is mounted at above the other two motorized conveyors with dough conveyor belts, namely one first upper conveyor 14 and a second lower conveyor 16.
- the two conveyors 14 and 16 jointly constitute a dough conveying station between the entry thereof, constituted by a first end 18 of the upper conveyor 14 located opposite a dough rolling station 20, and an intermediate point P, constituted by the opposite end 22 of this upper conveyor 14.
- the conveying station routes the dough pieces from the entrance to the intermediate point P in a forward path, through a rolling station 24 of the rolled dough pieces delivered by the station rolling 20, then, after having been transferred to a first end 26 of the lower conveyor 16, along a return path from the intermediate point P to the exit from the conveyor station, constituted by the opposite end 28 of this lower conveyor 16, located near the entrance to the transfer station.
- the rolling station 20 is constituted by the association of two laminating rolls, respectively 30 and 32, located opposite an inlet hopper 34 (not shown in Figure 1) allowing the feeding of the dough moulder .
- the upper and lower conveyor belts 14 and 16 circulate in the same direction represented by an arrow F in FIG. 2, the upper conveyor belt 14 being moved at a speed greater than that of the lower conveyor belt 16.
- the first conveyor 14 has an upper active face 36 delimiting the forward path and cooperating with a fixed mat 38 with which it forms the dough rolling station 24.
- This mat 38 is for example constituted by a flexible plate made of a material suitable for the intended use, for example in food-grade stainless steel wire. It ensures, together with the active upper face 36, the rolling of the rolled dough pieces, as is conventional.
- the upper conveyor 14 has a lower active face 40 extending parallel to the upper active face 36 and movable in opposite direction relative to the latter.
- the upper active face 42 of this lower conveyor 16 extends substantially parallel to the lower active face 40 of the upper conveyor 14 and is movable in the opposite direction relative to the latter.
- these two active faces 40 and 42 are slightly convergent and are distant from each other, at the intermediate point P by a distance corresponding substantially to the diameter of the rolled dough pieces delivered at the outlet of the rolling station 24 and, at the outlet 28 of the conveying station, by a distance corresponding to the diameter of dough pieces to be obtained.
- the molding machine comprises a transfer station 46 for rolled dough pieces, ensuring, in normal operation, the transfer of dough pieces from the outward journey to the return journey.
- the shaping machine furthermore comprises means for ejecting the double dough pieces blocked in the vicinity of the intermediate point P.
- These means for ejecting dough pieces blocked in the shaping machine comprise the transfer station 46 and a part of the upper active face 42 of the lower conveyor 16.
- the transfer station 46 is constituted by a third conveyor belt, arranged downstream of the outward journey and comprising an active surface 48 facing the intermediate point P and extending towards an interval 50 situated between the upper conveyors 14 and lower 16.
- the third conveyor 46 is motorized under the action of motor means 51 and has two operating modes, namely a normal mode, for transferring the dough pieces and an ejection mode intervening when a blocked dough piece is detected.
- ejection mode In ejection mode, it is driven in the opposite direction relative to the direction of rotation in normal mode, so as to drive the agglomerated and blocked dough pieces, together with the lower conveyor 16 through an ejection path 55, towards an oac ejection 53.
- the third conveyor 46 is driven in the ejection mode in the same direction as the direction corresponding to the normal transfer mode, but at a speed lower than that of the lower conveyor 16.
- the ejection is, in this case, slowed down , but also
- an ejection mode the belt of the third conveyor is fixed and possibly, the upper conveyor 14 is stopped or driven at a speed lower than that of the second conveyor 16 the latter causing the ejection of a blocked dough piece .
- the third conveyor 46 is mounted movable in translation on the chassis 12 around a position of stable equilibrium for receiving the rolled dough pieces, shown in FIGS. 2 and 4, in which the shortest distance between the facing surfaces of the first 14 and third 46 conveyors is less than the diameter of the dough rolls of normal size.
- the third conveyor 46 is mounted axially displaceable on the chassis 12 between a retracted position, shown in FIG. 5, allowing the passage of the rolled dough pieces beyond the intermediate point P and an advanced position for pushing the dough pieces between the first 14 and second 16 conveyors.
- the third conveyor 46 is provided with one or more transverse shafts 52 fitted, at their opposite end, with rollers 54 engaging in a groove 56 complementary for guiding this conveyor 46.
- the transverse strap 52 is connected, using a spar 58, to a spring 60, itself connected to a fixed part 62 of the chassis 12 by the 'intermediate of two parts, respectively 64 and 66 sliding relative to one another.
- the shaping machine further comprises means 70, 72, 76 for detecting the blocking of a dough rolled at the third conveyor 46. These means 70, 72, 76 control the means for ejecting blocked dough pieces.
- These detection means include an indicator 70, a corresponding sensor 72 and a control device 76.
- the indicator 70 is carried by the upper face of the beam 58 and that the corresponding sensor 72 is carried by the chassis 12.
- the indicator 70 and the sensor 72 are arranged such that the sensor can detect the equilibrium position of the conveyor 46. In response to this detection, it transmits a detection signal corresponding to the control device 76 to which it is connected by a electrical connection 74.
- the control device 76 comprises a counting unit 76A which, when a corresponding signal is present at its input side for a predetermined time, delivers an output signal.
- the output of the counting unit 76A is connected to an adjustment unit 76B.
- This adjustment unit 76B is connected to the motor means 51 by a second electrical connection 78 and is adapted to adjust the speed and the conveying direction of the conveyor 46 as a function of the signal delivered by the counting unit 76A.
- the adjustment unit 763 can be provided with control lines 80, 82 which are connected to motorization means of the first and second conveyors 14, 16.
- the moulder is completed by a recovery tray for shaped dough pieces, designated by the reference numeral 68, mounted on the chassis 12, and by the motorization means (not shown) of the first 14 and second 16 conveyors.
- the upper conveyor 14 is fixed on a fixed box relative to the chassis 12 and that the second 16 and third 46 conveyors are fixed on the same mobile box, adjustable in height (not shown), which is carried by the chassis 12, so that the spacing between, on the one hand, the first and second conveyors and, on the other hand, the first and third conveyors are adjustable simultaneously, depending on the diameter of the dough pieces to be obtained .
- the operation of this molding machine in normal mode and in ejection mode will now be described with reference to Figures 4 to 7.
- the rolled dough pieces are then driven under the action of the latter through the rolling station 24 at the outlet of which they are in the form of a cylinder, as shown in FIG. 4.
- the third conveyor 46 of the shaping machine is in its position of stable equilibrium. This position is detected by the sensor 72 and the corresponding detection signal emitted by the latter is transmitted to the control device 76. In response, the control device 76 controls the motor means 51 so as to drive the third conveyor 46 in the direction normal rotation.
- the conveyor 46 is therefore driven clockwise in FIG. 4.
- the rolled dough pieces are then successively transferred, at the intermediate point P, from the outward path to the return path under the action of the third conveyor 46.
- the sensor 72 delivers a signal corresponding to the counting unit 76A and the latter begins to count down the time during which the conveyor 46 is located outside from this position.
- the dough piece In the case where a normal dough piece is being transferred, the dough piece is pushed under the action of the return force of the spring 60, by the transfer station 46, towards the interval 50 and, is then driven between the two conveyors 14 and 16 under the action of the speed difference between them.
- the transfer station 46 After passage of the dough piece, the transfer station 46 is returned to its equilibrium position, and the sensor 72 again signals this position to the counting unit 76A before a threshold duration preset in this unit is exceeded, c that is to say a time from which it is decided that a dough piece is blocked and, therefore, before it delivers a detection signal of the blocking of a dough piece to the adjustment unit 76B.
- the counter of the unit 76B is then reset to zero and the unit stops counting as soon as the third conveyor 46 returns to its equilibrium position.
- the threshold duration is between 0.5 seconds and 2 seconds, preferably between 0.8 seconds and 1.5 seconds. It depends on the production rate. In a typical case, the transfer of a dough piece takes about a second and the threshold duration is between 1.2 s and 1.4 s.
- the transfer belt 46 remains outside its equilibrium position, that is to say in the retracted position, for a duration greater than the threshold duration. (for example between 1.2 and 1.4 s).
- the counter unit 76A observes the blocking of an agglomerated dough piece by detecting this overrun of the threshold duration and delivers a blocking signal to the adjustment unit 76B.
- the adjustment unit 76B controls the motor means 51 to drive the transfer belt 46 in the opposite direction (or, as a variant, stops the transfer belt 46), that is to say that the active surfaces of the second and third conveyors are driven in the same direction.
- the agglomerated dough is then entrained by the transfer belt 46 and the upper part 42 of the lower conveyor 16 through the space which is between the second and third conveyors 16, 46 along the ejection path 55 towards the tank. eject 53 ( Figure 6).
- the transfer station 46 is released and can thus return to its equilibrium position, under the action of the spring 60 ( Figure 7).
- the sensor 72 then again detects this position of equilibrium and the counting unit 76A resets the counter to zero and stops the counting. Simultaneously, the blocking signal is stopped, which causes the conveyor 46 to drive again in the normal direction, under the action of the adjustment unit 76B.
- control device 76 additionally controls the two upper and lower conveyors 14, 16 by means of control of the lines 80, 82 in such a way that the rolling of dough pieces is stopped or slowed down when there is a blockage up to that it be remedied.
- the third conveyor 46 is driven in the normal direction of rotation and the double dough piece is driven during a first phase through the space between the second and the third conveyors under the action of this third conveyor 46 alone if the first and second conveyors are stopped, or, if they are slowed down, by the second and third conveyors.
- the dough piece is driven by the surface 42 of the second conveyor towards the ejection tank 53.
- the third conveyor is stopped. It therefore no longer performs its function of transferring dough pieces.
- the dough pieces are ejected under the action of the second conveyor 16 towards the tank 53.
