(54) ROLLER BAKING DEVICE AND DISTRIBUTION SHEET

Technical field

The present invention relates to a device for the production of rolls of pastry crusts and separating sheets, with conveyors for delivering the pastry crust, especially to a multilayer dough, and to a separating sheet, in particular of baking paper, in a slot for inserting a fork a retractor which, when it enters the leading edge of the combination of dough crust and separating sheet, is rotated in motion and then drawn in an axial direction from the formed roll.

BACKGROUND OF THE INVENTION

It is known from EP-A-0230 335. With this device at the outlet end of the conveyor, the pastry binds are transferred under the force of gravity perpendicular to the retractor below the outlet end and are united in the slot for inserting the retractor with a separate, feeding, top separating sheet and with its help they are wound. The separating sheets are brought to a separate conveyor, which encompasses perforated conveyor belts driven above the suction boxes, and the last section to the slot for inserting the retractor releases each dividing sheet back. Since the inherent rigidity of mostly thin paper separating sheets is not sufficient for this purpose, each separating sheet has reinforcing ribs during transfer to the conveyor belts.

The disadvantage of this type of separation sheet feed is that it is extremely expensive and requires the installation of suction boxes, ribs and more.

In order to avoid contamination of the coil through the inserted pastry crust and to facilitate the removal of the formed rolls from the coil, it is suggested in the known construction to allow the separating sheet to precede the leading edge of the pastry crust, and then to make several rotations about the retractor before the bark is wound with it. Due to the limited inherent rigidity of the separator sheet, a temporary attachment of the leading section of the separation sheet to the driver is required. Temporary fixing is achieved either by means of a clamp attached to the retractor or by means of suction openings in the retractor, which in both cases requires additional control and feeding means.

SUMMARY OF THE INVENTION

It is an object of the invention to provide a device for the production of rolls of pastry and separating sheets, which is of a simplified construction, to guarantee production with little damage and with low maintenance costs.

The problem is solved with the device of the above type, which according to the invention is characterized in that the conveyor means comprises a device for laying a separation sheet on a circulating conveyor; a device for placing the pastry bark on a conveyor spaced apart, preferably in excess of the sum of the circumference of the retractor and the depth of the insertion slot, from the leading edge of the dividing sheet in the direction of displacement; a device for folding in the opposite direction of the portion extending before the dough crust from the dividing sheet on the upper surface of the front relative to the direction of displacement of the dough crust portion; as well as the device for inserting the front sections of the dough crust provided with a cuff from the dividing sheet into the slot for inserting the reel.

In this way, a common path is introduced for the insertion of the pastry and the separating sheets, avoiding the expensive treatment of the separating sheets. In addition, by bending the separating sheet on the leading edge of the dough crust, a winding process can be started, whereby the separating sheet cuff, at an appropriately chosen length, can simultaneously protect against the contamination of the coil, respectively. sticking the pastry crust on it. The use of expensive terminal and suction devices for initial fixing of the separation sheet on the retractor may be excluded.

A preferred embodiment of the invention consists in the fact that the separating sheet laying device has a feed roller of infinite starting material for the separating sheets and a cutting device for the starting material located above the conveyor. In this case, the device for laying pasta on the separating sheet is placed between the feed roller and the cutting device. Thus, the weight of the pastry used can be used to secure the separating sheet on the conveyor so that no special suction fixing of the separating sheet is necessary. According to another embodiment of the invention, the cutting device is controlled by a known sensor that captures the passage of the pastry so that the length of the separating sheets is adjusted to the actual length of the pastry fed.

Preferably, it is when the baking apparatus on the separation sheet is formed as a power strip terminating above the outlet end of the conveyor. Thus, the available output of a generally conveyor-shaped, conveyor belt machine for the production of a roller coaster carrier may be used.

In another embodiment of the invention, the device for folding the forward portion of the separating sheet has an upwardly aspirated nozzle, preferably a blower crossbar. This allows the section of the separator sheet to be lifted without damaging, tearing or contaminating the pastry. It is preferable to provide a folding line after the inlet nozzle, respectively, in the inlet crossbar that extends transversely to the conveyor a limited distance above it, in order to fold the cuff of the separating sheet back and temporarily lock it to the next process. of winding.

It is preferable for the reel to have two cylindrical winding guides fastened at one end axially, parallelly and eccentrically to a hub, which is supported by the possibility of rotation of a sled driven by a linear actuator. The cylindrical shape of the winding guides guarantees a particularly gentle treatment of the pastry during the winding process. From EP-A-0

230 335, it is known to use a twin-axle, axial axle, winder, but in the known construction, the winder has the shape of a radially grooved cylindrical rod, so that due to the sharp edges of the slot for inserting the winder, there is a danger of breaking the pastry crusts.

It is preferable for this type of reel when it is rotated by means of a guide washer which has two eccentric openings for sliding passage of the winding guides and is actuated by a rotary actuator and, upon withdrawal of the reel from the roll, forms a reducer for the axial roll fixing. This is a particularly simple and with the potential for a little damage to the type of the coil's rotary actuator.

According to another preferred embodiment of the invention, the device for inserting the front portion of the dough bundles provided with a cuff from the separating sheet into the slit insertion slot comprises a guide shield disposed on one side of the coil separating the dough bark from the dividing sheet cuff and bringing it into the insertion slot and a feeder shield located on the other side of the retractor. This allows the pastry to be supported on both sides of the coil and reduce the risk of shortening.

It is appropriate for the guide shield and / or the deflection shield to be radially retractable from the retractor by means of mounted linear actuators so that the leading shield or deflection shield can be as close as possible to the retractor during the process power supply to improve the support of the pastry crust and, on the other hand, to return to the starting position so as not to interfere with the rotation of the reel.

In another embodiment, a sensor is provided which captures the passage of the guide portion from the dough crust, provided with a separating sheet cuff, through the reel, and permits the insertion of a control device that controls a predetermined sequence of time intervals and linear actuators to draw the guide , the false shield, respectively; the retractor actuator of a reel of a predetermined number of revolutions; a linear actuator to pull out the reel and to return all linear actuators to their original positions. This type of control automatically adjusts to the actual length and the actual distance from the pastry bins.

The invention also includes an apparatus having two or more roll winding devices according to the invention, characterized in that the devices are arranged parallel to each other and separate a common conveyor, a common drive unit of the guide washers of the winding, common linear drive devices for the leading and the deflecting shield, in which the windings with their free edges are facing each other and are axially spaced relative to each other.

The performance of such a device is two or more times that of a single device without multiplying the structural elements to the same extent.

Description of the attached figures

The invention is explained in more detail with the aid of the accompanying drawings, where:

Figure 1 shows the device in side view;

2 is a top view device; 3 is a front view device, viewed from the outlet end of the conveyor;

Figures 4 and 5 are enlarged partial sections of the conveyor of Fig. 1, showing in detail the winding section (Fig. 4) and the inlet section (Fig. 5).

Examples of carrying out the invention

FIG. 1-5 The plant comprises two parallel production lines for the production of buns of rolls of pastry and separating sheets, as can be seen in particular in Fig. 2. In particular, the apparatus has a horizontal conveyor 1 which rotates counterclockwise about the first 2 and second 3 drums. The drum 3 is driven by an electric motor 4 through a drive belt. A tensioning roll 5 is also added to the conveyor.

Conveyor 1 is placed side by side and adjacent to each other two webs 6 of infinite starting material for the separating sheets of the rolls produced. The webs 6 are drawn from the feed rollers 7 located in the section under the shaft 2 of the conveyor 1, of which only the front can be seen in Figure 1. Other feed rollers 8 may be provided below the feed rollers 7.

The most commonly used separating and starting material is paper, baking paper, plastic film, aluminum foil and others. The device is not limited to a particular type of leaf-splitting material.

The dough bins prepared in advance by the (not shown) rolling dough and the cutting machine are transferred to the webs 6 moved by the container 1 into the device shown in FIG. The transfer of the pastry blades 9 to the web 6 for the separating sheets may be, for example, by means of a conveyor belt terminating above the receiving end of the conveyor 1 (not shown).

Between the feed belt and the conveyor 1, the pastry bark 9 passes through a sensor designed, for example, as a photocell that captures the passage of the bark 9.

The device described here can be loaded with any type of dough; one preferred area of use, however, is the processing of multi-sheet dough.

The webs 6 for the separating sheets with the pasta blades 9 lying on them come under a shaft of foam material 11 (FIG. 5) and pass through a cutting device 12 designed as a scissor, which cuts the web 6 immediately after the back edge 13 of the baking bins 9 of separate dividers. sheets 14. The actuation of the cutting device 12 is controlled depending on the feed of the pastry 9 through the sensor 10.

Instead of passing the pastry blades 9 between the feed rollers 7 and the cutting device 12, the transfer of crusts can only take place after the individual separating sheets 14 of the conveyor are laid, for example after a combination of feed rolls 6 and cutting devices 12, but the construction shown has the advantage that the own weight of the pastry bark 9 fixes the web 6 before cutting, respectively, the separating sheets 14 after cutting.

Finally, the separating sheets 14 together with the pasta blades 9 therein pass through a device 15 for folding the baking trays 9, portions 16 of the dividing sheets 14 back to the upper sides on the guide portions 17 of the bark 9. This device comprises a nozzle provided with upward pressure air, respectively, a blowing crosspiece 18, and a subsequent bending line 19 transversely to the conveyor 1, followed by a foam press roll 20. The guide portion 17 of the dough crust 9 is thus secured with a cuff from the separating sheet.

The pasta blades 9, which are resting on the separating sheets 14 and secured by the cuff of the separating sheet, come finally under the transverse, clamping rails 21 and under the height-adjusting clamping roll 22 of foam material to the winding device 23. In this, they are separated from the upper surface of the conveyor. 1 through a guide shield 24 and are introduced into a slot 25 for inserting a winding 26. The winder 26 consists of two cylindrical guides, which at one end are fixed axially, parallel and eccentrically to the hub 28, which in turn is supported and with the possibility of rotation in the carriage 29 (Fig. 3). The carriage 29 is driven in the axial direction by means of a linear actuator 30 in the form of a pneumatic cylinder.

There is one reel 26 on each side of the conveyor 1 so that two rolls can be produced in parallel (Figure 2). The wound 26 are facing each other with their free sides and are assembled axially to each other. For both coils, a common rotary actuator 31 with a shaft 32 is provided, on which are belt pulleys 33 that drive the coils 26 through timing belts 34 and a guide washer 35. Each guide washer 35 has two eccentric slots for sliding penetration of the winding guides 27 .

On the back of the guide shield 24 side of the winders 26 is mounted a guide shield 36, which together with the guide shield 24 serves to support the cuffed section 17 for the dough bark 9. For this purpose, both the guide shield 24 and the guide Shield 36 is brought as close as possible to both sides of the winder 26 and is movable so that it can be radially disengaged when the winder 26 is rotated. More specifically, the guide shield 24 is attached to a movable part of the linear actuator 37, such as, for example, a pneumatic cylinder. Similarly, the deflection shield 36 is secured to the movable part of a linear actuator 38, which is also a pneumatic cylinder.

A sensor 39 is mounted on the drop shield 36, which catches the passage of the cuff section 14 of the pastry 14 supplied through the cuff 26 through the reel 26, in particular the uptake of that portion by the feed shield 36 and permits the inclusion of a control device (not shown), which sequentially controls in time first the linear actuators 37 and 38 to pull the guide 24 and the deflector shield 36, and then includes the rotary actuator 31 for the winders 26 of a predetermined number of turns and finally drives the linear drive units 30 of the sleds 29 to pull the retractors 26 from the formed rolls. The winding guides 27 are then removed from the openings of the guide washers 35, which also serve as restraints of the formed rolls for their axial fixation.

The turn of the winders 26 is carried out in the direction of the arrow 40, whereby the number of turns of the control device is transmitted by the speed control device 41 connected to the shaft 32 of the rotary drive device 31. By bending the section 16 of the separator emerging before the test crust 9. sheet 14, the winding guides 27 - at the appropriate choice of the length of the cuffs of the separating sheet - come into contact exclusively with the separating sheets 14, which avoids contamination through the pasta bark 9, or gluing them 9 on retractors 26. In particular, the length of the separator sheet cuff must be at least equal to the sum of the depth of the insertion slot (corresponding approximately to the diameter of the coiling guide) and the circumference of the coil.

After removing the coils 26, the shaped rolls fall back onto conveyor 1 and are transferred to the outlet end of conveyor 1, where they are available for further processing, such as packaging. After a predetermined time interval, the control unit returns the linear actuators 30,37 and 38 back to their starting positions again so that the winding device 23 is ready to absorb and twist the next batter, provided with dividing sheets.

The whole device is mounted on a movable stand 42, which also carries a communication cabinet 43 for electrical and pneumatic control. By means of transporting the stand 42, the entire facility can be moved and positioned to an outlet power strip of a pastry making machine.

Although the described device comprises two adjacent devices for parallel production of two rolls, the two devices separate a common conveyor 1, a common drive unit for the cutting devices 12, a common rotary drive unit 31 for the guide washers 35, and a common linear actuators 37.38 for the leading and respectively deflecting shields, it is understood that an alternative may be provided for a single device to produce one roll at a time.

Other alternative embodiments of the presented device include laying pre-cut, consisting of separate parts, separating the conveyor leaves, on which the bark is then transferred, folding the separating sheets with the help of upward brushes and folding lines, or rolls, the use of a significantly shorter cuff than a separating sheet to save material, which in particular facilitates only the insertion of the combination of pastry and a separating sheet into the slot for inserting ace, the failure of any leading or advancing shields, the installation of otherwise shaped winders as they are known in the art, the use of any, whatever actuator, whether pneumatic, hydraulic, electric or otherwise, as described actuators, respectively the use of any known sensor types instead of the sensors described.
