Description

PIVOTABLE BANDUM FLOW FOR DELIVERY SINGLE CHAMBER IN WEIGHING DEVICE FOR DOUGH AND ACTUATORS

The invention relates to a device for working and processing dough according to the preamble of patent claim 1.

Devices are known from the prior art, with which dough is transferred from a dough drum in a transfer area to an operating drum. In the transfer area a stripping roller is arranged, with which the spreading of the dough from the dough drum is supported. However, such wiping rollers are only suitable for solid doughs, since loose or soft and sticky doughs with a high dough yield tend to adhere to the wiping roller. To detach the dough from the stripping roller, such devices further comprise a scraper and / or an oiling device for the stripping roller. In order to ensure the detachment of the dough from the stripping roller, it is operated at a high circumferential speed in order to release the dough pieces from the partial pistons of the dough drum and to prevent them from adhering to the stripping roller by the resulting centrifugal force. If the speed is too low, stick the dough pieces to the roller itself, the speed is too high, the surface or the skin of the dough is torn open, which prevents or deteriorates a transfer into the operating drum. The individual parts of the dough pieces then stick to the drum and are not worked properly.

Disadvantage of the devices known from the prior art is that they only work reliably with solid doughs, but the dough pieces, especially in the case of sticky doughs, do not dissolve or only dissimilarly, which negatively influences the result of the effect. Furthermore, the dough is not triggered reliably when released from the dough drum, which causes a variation of the piece weights of the dough pieces and thereby increases the rejects.

Object of the present invention is therefore to provide a device of the type mentioned above, on the one hand allows a reliable transfer of dough pieces from a dough drum in a drum and at the same time can serve a wide range of different doughs.

The object is achieved in a device of the type mentioned by the characterizing features of claim 1. It is provided that in the transfer area, at least one rotatable roller is arranged, which of a Discharge belt, in particular the band of the operating drum, at least partially looped, wherein the roller is configured and arranged such that dough is transferred from the receiving chambers of the dough drum to the operating drum in the transfer area with the discharge belt, in particular the belt, can be brought into contact and such, in particular completely, can be discharged from the respective receiving chambers and introduced into the operating drum.

Due to the arrangement of the roller, which is looped around with the band of the operating drum, the dough can be peeled out of the receiving chambers in the transfer area and introduced directly into the active chambers of the operating drum. Since the tape wraps around both the reel and the reel drum, an additional release device from the reel is not necessary as the dough can be further processed directly by the movements of the reel drum in the active chambers. The inventive design achieves a very simple and reliable construction that requires no additional features and simplifies maintenance and no other additives such as release agent requires, which causes maximum production safety.

Further optional, advantageous embodiments are defined by the dependent claims:

It is advantageously provided that the roller and / or the discharge belt, in particular the belt, rests on the circumference of the dough drum in the transfer area or is arranged at a small distance, in particular at a distance of 0.05 mm to 10 mm, to the dough drum.

The arrangement of the roller at the end of the pivot lever, it is possible that the roller is arranged in the discharge position in the transfer area and can peel the dough from the receiving chambers of the dough drum and can bring into the active chambers of the processor drums. By pivoting the drum by means of the pivot lever in the open position dough, which is located in the receiving chamber of the dough drum, be passed without touching the roller. This is particularly advantageous for very bulky doughs, since these tend to increase their volume after the Auswiegeprozess in the receiving chamber and swell out to a portion of the receiving chamber. Furthermore, it is advantageous that the roller with the pivot lever at the time of transfer of the dough or dough from the receiving chamber of the dough drum in the active chamber can take a targeted position. In the discharge position is effected by the position of the role further that the dough pieces are pressed by the band, which is also applied to the operating drum, in the active chambers of the operating drum and thus the beginning of the kneading process is guaranteed.

It is advantageously provided that the distance between the roller and the dough drum in the open position is greater than 5 mm, in particular 15 mm, and / or that the roller and / or the discharge belt, in particular the belt, at the periphery of the dough drum in the transfer region in the discharge position of the pivot lever is present or at a small distance, in particular at a distance of 0.05 mm to 10 mm, is arranged to the dough drum.

An advantageous embodiment of the invention is provided by a deflection roller is arranged on the roller opposite the end of the pivot lever, wherein optionally the discharge conveyor, in particular the belt, is partially guided around the deflection roller.

The arrangement of the deflection roller on the pivoting lever improves the tension of the discharge belt or the belt and increases the wrap angle of the belt around the operating drum in the open position of the pivoting lever, whereby the effective range of the operating drum is increased and the introduction of the dough is improved in the active chambers of the operating drum , A structurally simple to implement embodiment of the device form is provided by the pivot lever about its center, in particular about the center of the distance between the roller and the guide roller, is pivotable or rotatable.

FIG. 6 shows a further isometric view of the embodiment of the pivoting lever illustrated in FIG. 5. Fig. 7 shows an isometric view of an embodiment of the pivot lever with roller and pulley.

In Fig. 1, a first embodiment of the device 10 according to the invention is shown in a sectional view. The device 10 comprises an operating drum 1 rotatable about its axis, which is surrounded by a band 2 in a partial region of the circumference. The Impact drum 1 has a number of active chambers 1 1, which are distributed uniformly over the circumference of the drum 1. The device 10 further comprises a dough drum 3, which comprises a number of receiving chambers 31, in each of which a weighing punch 32 in the radial direction of the dough drum 3 is linearly adjustable. The dough drum 3 is arranged circumferentially to the operating drum 1 at a distance, so that the dough drum 3 and the operating drum 1 just do not touch. With respect to the longitudinal extent of the dough drum 3 and the operating drum 1, these are positioned in alignment with each other so that one of the receiving chambers 31 can be brought into correspondence to one of the active chambers 1 1 of the operating drum 1 with corresponding rotation of the operating drum 1 and the dough drum 3 about its center, so that a dough located in the receiving chamber 31 can be transferred from this to the active chamber 1 1 of the operating drum 1 in a transfer region 4. In the transfer area 4 a rotatable about its central axis roller 5 is arranged, which is also partially wrapped by the band 2, which wraps around the operating drum 1, so that the band 2 extends from the roller 5 in the transfer area 4 to the operating drum 1 and this partially wraps around , The roller 5 is arranged circumferentially at a small distance from the dough drum 3 and extends over the entire length of the dough drum 3. Since the tape 2 is guided around the roller 5, the tape 2 also has the same or almost the same distance to the dough drum 3 like the roller 5. The distance between the roller 5 and the belt 2 to the circumference of the dough drum 3 in the transfer area 4 in this embodiment is 2 mm. The distance between dough drum 3 and the roller 5 or the belt 2 can be selected depending on the dough, but is preferably between 0.05 to 10 mm. According to the invention, the roll 5 is arranged in the transfer region 4 such that dough which is located in the receiving chamber 31 of the dough drum 3 and is transferred to the active drum 1 in the transfer region 4 can be brought into contact with the strip 2. As a result of the rotation of the operating drum 1, for example in the counterclockwise direction and thus the movement of the belt 2 and the rotation of the roller 5, dough which is located in the receiving chamber 31 of the dough drum 3 is peeled out of the receiving chamber 31 by means of the belt 2 in the transfer area 4 and thus completely discharged from the receiving chamber 31. By guiding the tape 2, the dough scraped out of the receiving chamber 31 by means of the tape 2 is then introduced or transferred into the active chamber 1 1 of the operating drum 1 positioned opposite the receiving chamber 31 of the dough drum 3.

In FIGS. 2 to 3, three functional states of a second embodiment of the device 10 according to the invention are shown in section. The device 10 comprises a pivot lever 6 which is pivotable or rotatable between a discharge position and an open position. The device 10 is shown in an open position of the pivot lever 6 (FIG. 2), in the discharge position of the pivot lever 6 (FIG. 3), and in an intermediate position of the pivot lever 6 between the open position and the discharge position (FIG. 4). At one end of the pivot lever 6, the roller 5 is arranged and at the opposite end of the roller 5, the pivot lever 6 is a guide roller 7, which is partially wrapped by the band 2, arranged. The pivot lever 6 is pivotable about its longitudinal extent or about the longitudinal extension of the roller 5 and the guide roller 7 and rotatable, whereby the distance between the roller 5 and the guide roller 7 to the operating drum 1 and the dough drum 3 is variable. In Fig. 2, the pivot lever 6 is shown in its open position. The roller 5 has a maximum distance from the circumference of the dough drum 3, so that dough, which is received in the receiving chamber 31 of the dough drum 3, upon pivoting of the dough drum 3, the roller 5 can pass without touching or abut this. The distance of the roller 5 to the dough drum 3 is 15 mm in the open position and is advantageously greater than 5 mm according to the invention.

In Fig. 3, the pivot lever 6 is shown in its discharge position. In the discharge position of the pivot lever 6, the roller 5 has a minimum distance from the dough drum 3. The distance between the circumference of the dough drum 3 and the roller 5 and the belt 2 guided around the roller 5 is 0.05 mm. According to the invention, the distance between the circumference of the dough drum 3 and the roller 5 or the belt 2 is 0.05 to 10 mm, so that dough which is located in the receiving chamber 31 of the dough drum 3 with the belt 2 and the roller 5 in contact can be brought or comes into contact and is peeled out by the orbital movement of the belt 2 around the roller 5 and the active drum 1 from the receiving chamber 31 of the active drum 3 and in the active drum 1 and 1 in the active chamber 1 1 of the drum 1 can be introduced ,

FIGS. 5 and 6 show a preferred embodiment of the device 10 according to the invention without dough drum 3 and drum 1. In this embodiment or in the other embodiments, the device 10 optionally has a band tensioning device 9 which acts on one end of the pivoting lever 6. The band tensioning device 9 has a tensioning lever 91 (FIG. 5), which engages in an adjusting mechanism 92. Mitteil a crank 93 (Fig. 6), the position of the clamping lever 91 and thus the position of the pivot lever 6 is adjusted. The adjusting device 92 in this case has an actuatable via the crank gear, which engages in a counter-trained on the clamping lever 91 rack and the clamping lever 91 thus linear adjusted. The band tensioning device 9 gewä ensured on the one hand, the adjustment of the tension of the belt 2 via rotation of the crank 93 and the position of the clamping lever 91, and on the other hand, the adaptation of the band profile of the belt 2 to the position of the dough drum 3 and the operating drum 1 and thus the position the roll 5 in the transfer area 4. As a further advantage, the course of the belt 2 can be adapted to the diameter of different, used operating drums by means of the belt tensioning device 9. Optionally, the band tensioning device 9 may have a suspension 94 which absorbs the adjustment movement of the pivoting lever 6 between the open position and the discharge position. Thus, it can be prevented that in position change of the pivot lever 6, the tape 2 lifts off from the operating drum or the voltage of the belt 2 is changed in the Umschwenkbewegung the pivot lever 6.

A preferred embodiment of the pivoting lever 6 is shown in Fig. 7 in isometric view. The pivot lever 6 has an elongated connecting piece 61, at the two ends of which two flange pieces 62 are arranged. The flange pieces 62 are formed in an oblong or oval symmetrical manner and are fastened centrally about their central axis on the connecting piece 61. At one end of the flange pieces 62, these are each connected to the roller 5, which is made in three parts in this embodiment. At the opposite end of the roller 5 of the flange 62, the guide roller 7, which is also formed in this embodiment, three parts attached or arranged. The pivot lever 6 is about its center, ie the means of the flange pieces 62 and about the middle of the distance between the roller 5 and the guide roller 7, pivotable or rotatable. The pivot lever 6 can be pivoted by a drive by means of a control lever 64 between the open position and the discharge position. As an abutment or support of the pivot lever 6 on the housing of the device 10, an abutment 36 is formed at the center of the adjusting lever 64 opposite end of the pivot lever 6.

In the following, the function of the device 10 according to the invention will be described by way of example with reference to a preferred embodiment shown in FIGS. 2 to 4:

In a first step, dough is introduced into the receiving chambers 31 of the dough drum 3. In this case, for example, dough can be pressed into the receiving chamber 31 by means of a dispensing device which comprises a dispensing slide 33 and an ejection lever 34 (FIG. 2). Due to the linear displacement of the stamping punch 32 within the receiving chamber 31 in the direction of the center of the Dough drum 3 is released space in the receiving chamber 31 for the dough, which is shown dotted in Fig. 2, and the Auswiegeschieber 33 can thus press the dough into the receiving chamber 31. In a further working step (FIG. 2), the dough drum 3 is pivoted with the receiving chamber 31 in the direction of the operating drum 1, so that the receiving chamber 32 and one of the active chambers 1 1 of the operating drum 1 face each other in the transfer area 4. Since the pivot lever 6 is in the open position, that is, the roller 5 has a distance from the dough drum 3, the dough, which is located in the receiving chamber 31, can be conveyed into the transfer area 4, without on the belt 2 or on the roller fifth to adhere to or come into contact with it.

Now, if the dough drum 3 at the end of the pivoting operation with the receiving chamber 31 with respect to one of the active chambers 1 1 of the operating rollers 1 positioned, the pivot lever 6 is pivoted to the discharge position (Fig. 3). In the discharge position of the pivot lever 6, the roller 5 and the belt 2 to the dough drum 3 a minimum distance. At the end of the pivoting operation of the dough drum 3, the stamping punch 32 is moved in the direction of the circumference of the dough drum 3, and thus the dough located in the receiving chamber 31 is discharged from the receiving chamber 31. In particular, in the case of sticky doughs usually the expressing movement of the ram 32 is not sufficient to bring the dough completely out of the receiving chamber 31, so that the dough adheres to the ram 32 and thus can not be discharged from the receiving chamber 31. Now, if the dough drum 3, as shown in Fig. 3, again adjusted in the direction of the balancing device, not shown, the dough enters the roll 5 and the part 5 around the part 2 partially guided band in contact and by the band 2 and the roller 5 is completely discharged from the receiving chamber 31.

Subsequently, the dough drum 3 is further pivoted in the direction of the ejector slide 33 and in the direction of the deflection device and the pivot lever 6 is moved back into the open position. By rotation of the active drum 1, the belt 2 or the roller 5 is set in motion and a possibly adhering to the belt 2 dough is pressed into the active chamber 1 1 of the operating drum 1. By the further promotion or rotation of the drum 1 and the associated further movements of the belt 2 ensures that the dough - represented by the dotted in Fig. 4 moldings - introduced into the active chambers 1 1, the contact with the drum 1 and ensured it is ensured that the knitting process can be started. By the action drum 1, the individual dough portions or dough pieces are kneaded or deformed, then discharged from the action drum 1 and conveyed on the belt 2.

Optionally, as shown in FIGS. 2 to 4, the device 10 may have a flour staking device 8, with which flour is applied to the strip 2. The flour-dusted belt 2 further reduces the adhesion between the belt 2 and the dough and thus improves the detachment of the dough from the receiving chamber 31 and the detachment from the belt 2 into the active chambers 1 1 of the operating drum 1. Alternatively, instead of a Bemehlungsvorrichtung 8 also a lubrication device may be provided, is applied to the oil on the belt 2.

The band 2 which at least partially spans the operating drum 1 in the embodiments described in FIGS. 1 to 4 at the same time as a so-called knitting tape which guides the dough pieces into the operating drum 1, generates the pressure required for the kneading process by the belt tension on the dough pieces and the dough pieces are transported from the operating drum 1 to the end of the belt 2 or its return (FIG. 4) and then delivered to another belt or removed from the belt 2.

In an alternative embodiment, not shown, in addition to the band 2 of the actuating drum 1, the device may also have a discharge belt. The discharge belt is guided around the roller 5 instead of the belt 2. The discharge belt can then be arranged analogously to the embodiments described in FIGS. 1 to 4 instead of the belt 2. The Austragsband would then peel the dough from the active chambers 1 1 and bring in the transfer area 4 in the active chambers 1 1 of the drum 1 in which then the band 2 covers this in the course or in the transfer area 4, the dough directly to the tape 2 Transferring drum 1.

The belt speed of the discharge belt or of the belt is advantageously at least 70%, preferably greater than or equal to 100%, of the peripheral speed of the dough drum 1.
