Description

Oven transfer device with laterally displaceable conveyor belt

The invention relates to a method and a device for transporting

Moldings of a receiving area in a transfer area and for transfer to a transport surface, such as a baking belt baking machine, wherein the device for transporting the moldings comprises a revolving, driven conveyor belt, which is at least one deflection roller, a drive roller and in the transport area around a Transfer body is guided.

The field of the invention relates to devices for the transfer of moldings, such as unbaked dough pies, unbaked biscuit moldings, unbaked dough pieces, etc., and in particular oven transfer tapes for transferring flat, unbaked Keksteig moldings onto the hot baking belt of a baking machine. In order not to damage the moldings during the transfer, the moldings must be passed as gently as possible from the transfer belt on the baking belt. For this, the transfer belt is guided as close as possible to the belt. The transport surface, to which the substantially limp biscuit moldings are transferred, is not arranged stationary according to the state of the art, but undergoes a certain movement. In the case of tapes of a

Baking machine is on the one hand the movement of the conveyor belt in

Transport direction given. In addition, however, the baking belt has a lateral movement component transversely to the transport direction of the baking belt, which is caused by a backlash-bearing of the baking belt. A rigid side guide of the tape is not possible because this guide leads to increased wear or damage to the baking belt.

Accordingly, the conveyor belt of the oven transfer device must be tracked and / or adapted to the lateral movement of the oven belt.

The prior art devices, for example, have a machine frame, which can be rotated relative to the baking machine about a pivot point. The transfer area of the furnace transfer device can thus also be moved about this pivot point to the lateral movement of the

Balance backbands. The disadvantage of this construction is that the

Oven transfer device and the transfer area of the furnace transfer device relative to the transport surface of the baking machine to be moved. However, this movement deviates from the pure lateral movement of the baking belt of the baking machine. This results in a change of the transfer gap depending on the position and location of the two devices. Especially with thin, small and / or limp cookie moldings, this can lead to damage during the transfer.

Another disadvantage of this construction is that the bands of the

Transfer devices are designed as plastic bands. These are not sufficiently heat-resistant, so that they can be guided close to the baking belt of the baking machine without damage. Also from this disadvantage results in a larger transfer gap and thus a poor quality transfer.

The object of the invention is now to overcome the disadvantages of the prior art

overcome and thereby create a device that is of a high quality Transfer of moldings allowed on a transport surface. This includes the

Subtasks that the transfer gap is kept as small as possible that the

Transfer radius is optimized that the positioning of the transfer area of the device is adapted to the lateral movement of the transport surface of the baking machine, and that while the transfer gap is kept substantially constant.

It is another object of the invention, the high-quality transfer of im

Essentially pliable moldings on a hot baking surface of a

To enable baking machine.

Furthermore, this also includes the tasks that the construction of the device is maintenance-optimized and low in production.

The object of the invention is achieved in that the conveyor belt is laterally displaceable over a positioning device at least over a portion of its longitudinal extent.

Further features of the invention are that the conveyor belt via a

Positioning device is partially offset laterally that

the transport direction and the lateral position of the conveyor belt in

Receiving area is kept constant at the lateral displacement of the conveyor belt, that the conveyor belt in the transfer area is laterally displaceable, that the conveyor belt in the transfer area on the positioning along a transfer body following transfer contour is laterally displaceable, that the

Positioning device comprises at least one positioning means for guiding the conveyor belt and / or that the positioning means is movable via an actuator.

Furthermore, the invention is characterized in that the positioning means is coupled to the transfer body, and that the transfer body is movable transversely to the transport direction via the actuation of the actuator that two positioning means are provided for lateral guidance of the conveyor belt, that the actuator is a mechanical or a elektromechanäsches Actuator such as an electrically driven linear axis, a pneumatically driven linear axis, a hydraulically driven linear axis or a crank mechanism comprises a Detection device for detecting the lateral position of the transport surface is provided, through which the lateral displacement and / or positioning of the conveyor belt in dependence on the lateral position of the transport surface is enabled and / or that the detection device is a mechanical or

electromechanical detection means, such as a displacement sensor, an optical sensor, a microswitch, a reed sensor or a mechanically movable roller.

According to the invention may further be provided that the transfer body is designed as a transfer knife, preferably as a transfer knife with a sharp transfer contour that the drive roller is arranged in the transport direction after the receiving area and before the transfer contour that the guide roller, the drive roller and the transfer body in one arranged rigidly opposite the machine

Machine frame are arranged or mounted and / or that the drive roller is laterally rigidly coupled to the machine frame and that the positioning means and / or the transfer body is laterally movable relative to the machine frame.

Further features may be that the transport direction laterally deviates laterally from the transport direction in the transfer area in the transfer area, that the axes of the guide rollers, the drive roller and the transfer contour are substantially parallel to one another that the transport belt as

discontinuous belt, in particular as a discontinuous metal belt, preferably as a spiral belt belt, is executed and that the conveyor belt is relieved in the starting region of the transfer contour substantially resistance train. In particular, the use of a discontinuous metal strip such as a

Spiraigfiedergurtes advantageous if the moldings on a hot Transportfiäche such. the baking belt will be handed over to a baking machine. The discontinuous metal strip is characterized by the fact that it is heat-resistant and can be guided close to the baking belt of the baking machine. This improves the quality of the transfer.

Furthermore, the invention is optionally characterized in that the

Has conveyor belt in the starting region of the transfer contour or in the region between the drive roller and the transfer contour the lowest tensile stress, and / or that the conveyor belt has a substantially constant green voltage and a resistance voltage generated by friction, and that in the starting region of the transfer contour or in the region between the drive roller and the transfer contour, the conveyor belt is substantially free of resistance voltage, or in this range only the base voltage acts.

Furthermore, the invention relates to a method, characterized by the following steps: the shaped body is conveyed on a revolving, driven conveyor belt from a receiving area into a transfer area; a detection device detects the lateral position of the transport surface; the conveyor will be in

Dependence of the lateral position of the Transportfiäche laterally offset in the transfer area; the shaped body is transferred via a transfer contour and a transfer gap on the transport surface.

The method according to the invention can also comprise the steps that the

Transport belt is tracked by a lateral displacement in the transfer region of the lateral position of the transport surface, and / or that the lateral position and the transport direction of the conveyor belt are kept constant in the receiving area.

Moreover, the invention relates to a Keksbackofen, which is characterized in that a device according to the invention is provided.

According to the present invention, the device has a positioning device, by means of which the conveyor belt can be positioned at least in the transfer region as a function of the lateral position of the transport surface. For this purpose, a detection device is provided which detects the lateral position of the transport surface. In this case, the direction which is essentially transverse to the transport direction of the conveyor belt or the transport surface is referred to as the side. in the

Transfer area, the conveyor belt is guided around a transfer body. In this area, in particular in that area in which the transported moldings at least partially leave the conveyor belt, a transfer contour is formed. The transfer contour essentially follows the transfer body and / or the

Conveyor belt in the area of the transfer body. The transfer contour is a flat or linear contour in that region of the conveyor belt, in which the

Mold body leaves the conveyor belt. The deflection of the conveyor belt on Transfer body is preferably designed such that the conveyor belt is deflected about an approximately horizontally extending transfer contour in the direction of gravity. The deflection angle is at least 90 °, preferably 90 ° to 180 °. The deflection angle is preferably measured in a vertical plane which extends in the transport direction. Between the transport surface of the machine and the transfer contour is the transfer gap. This is optimized in shape and size and kept constant in a preferred manner with lateral positioning or displacement of the conveyor belt. To keep constant the transfer gap, the conveyor belt is moved or offset in the transfer area along the transfer contour.

Furthermore, the device according to the invention has a receiving area for receiving the shaped bodies. This is preferably arranged in a region of the conveyor belt, which has a certain distance to the transfer area. In

Preferably, the lateral position of the conveyor belt is kept constant in the receiving area. This means that with lateral displacement of the conveyor belt in the transfer area, the conveyor belt in the receiving area no lateral

Transfers experience.

For this purpose, conveyor belts are used, which are laterally displaceable and in particular allow a parallel displacement. In a Paralleiversetzung the conveyor belt can be partially offset laterally. This displacement occurs almost exclusively in the area formed by the conveyor belt. There is no buckling or twisting of the conveyor belt. This assumes that the conveyor belt has lateral flexibility. For example, discontinuous metal bands such as spiral belts are suitable for use in the device according to the invention. These have transverse elements which run essentially normal or transverse to the transport direction. The transverse elements are connected by spiral elements in a chain shape and laterally, relative to each other, displaceable. In particular, the transverse elements are displaceable parallel to each other and thereby connected to each other by the spiral elements.

The device according to the invention is preferably used "inline" in a line for the industrial production of bakery products, In particular, the device is designed to have substantially flexible moldings, such as, for example, uncooked biscuit moldings of, for example, a cut-out device Formation example, round biscuit to a transport surface, for example, to convey the oven belt of a cookie baking oven. This means further that the

Control unit of the drive and the actuators of the device is optionally connected to the control unit of a baking machine or an entire production line. Otherwise, an independent control unit of the device can be provided via which the drive of the conveyor belt, the lateral displacement of the conveyor belt and / or other parameters are controlled.

In this context, it is defined that an actuator substantially corresponds to a component which can perform a controlled and / or a controlled movement. Examples of actuators are pneumatic drives such as

Pneumatic cylinders, hydraulic drives such as hydraulic pistons or hydraulic cylinders, electric drives, linear axes, etc.

As a substantially limp molded body, a body is defined, which has a low flexural strength - for example, raw biscuit body, dough pieces, etc. The transfer of these bodies is due to the lack of rigidity only possible over columns small column width, otherwise damage to the moldings would take place.

The invention will be further described by means of concrete embodiments and figures.

1 shows a schematic side view of a device according to the invention for transferring one or more moldings 1 from a conveyor belt 3 onto a transport surface 2. The conveyor belt 3 is guided around one or more deflection rollers 4 and around a transfer body 6. Furthermore, a drive roller 5 is provided in the course of the conveyor belt 3. This can be used as a deflection roller 4 or not

be executed deflecting drive roller. In addition, one of the deflection rollers 4 may be designed as a tensioning roller 18. In the present embodiment, the

Transfer body 6 designed as a cylindrical body. This may be rotationally rigidly coupled to the machine frame 13 or similar to a guide roller 4 rotatably mounted on the machine frame 13. In the transfer area 10, in which the shaped bodies 1 are transferred from the conveyor belt 3 to the transport surface 2 of a machine 7, a transfer gap 16 and a transfer contour 12 are defined. Of the

Transfer nip 16 substantially corresponds to the gap between the conveyor belt 3 and the transport surface 2 in the transfer area 10. The transfer contour is a flat or linear contour in that region of the conveyor belt in which the molded body 1 leaves the conveyor belt 3.

The drive roller 5 is in the present embodiment in the area in front of the

Transfer area arranged in the transport direction 17. At the cylindrical

Execution of the transfer body 6, however, it also corresponds to the

Invention idea to perform a different deflection roller of the device as a drive roller 5. In a region of the device facing away from the transfer body, the application area 15 is provided. In this the moldings are on the

Transport belt 3 abandoned. In the case of a device for the industrial production of biscuit, for example, limp, unbaked biscuit dough pieces are transferred from a cutter to the conveyor belt 3. The

Cutter and the means for transfer to the device according to the invention are usually arranged stationary. For this reason, according to the invention in a preferred manner, the conveyor belt 3 in the receiving area 15 is also stationary arranged. This means that the conveyor belt according to this embodiment and preferably according to the invention has no lateral freedom of movement or remains stationary on the side. However, the movement of the conveyor belt 3 in the transport direction 17 is given by the inventive arrangement of the guide rollers 4. To adapt the conveyor belt 3 to the lateral movement of the transport surface 2, an offset of the conveyor belt 3 is necessary. Preferably, the offset is done via a parallel offset. In the present view, a parallel displacement means that a partial displacement of the conveyor belt 3 takes place in a direction projecting in the present view.

To support the conveyor belt 3, in particular to assist against sagging due to gravity one or more guiding means 19 are provided below the conveyor belt. These conductive agents can be used, for example, as

be made strip-shaped the course of the conveyor belt 3 following conductive means. The conveyor belt 3 rests substantially on these guide means 19 and is moved along this movement. Furthermore, the device may comprise a funnel device 20 and a collector 21. The hopper device serves, for example, to supply impurities or excess spreading material in the collector 21.

FIG. 2 shows a further embodiment of a device according to the invention which, apart from the configuration of the transfer body, substantially corresponds to FIG. In the course of an endless conveyor belt 3, a plurality of deflection rollers 4 and a drive 5, a tensioning roller 18 and a transfer body 6 are provided. The conveyor belt is deflected in the transfer area 10 by the transfer body 6. In the present embodiment, the transfer body 6 is designed as a transfer knife. The transfer body thus has a sharp transfer edge, whereby the transfer contour 2 of the conveyor belt 3 also has a relatively small transfer radius. In order to keep the transfer gap 16 as small as possible, the conveyor belt 3 must be guided as close as possible to the transport surface 2. To avoid damage from heat, the conveyor belt 3 as

discontinuous metal band such as executed as Spiraigliedergurt.

The transport surface 2 corresponds for example to the baking belt of a baking machine. This is guided laterally playful in operation of the baking machine, so that the Conveyor belt 3 for transferring the moldings 1 also moved laterally and / or the position of Transportffäche must be adjusted. In the lateral positioning of the conveyor belt 3 is inventively provided that the transfer gap 16 remains constant. This means in a further consequence that the transfer contour 12

relative to the transport surface 2 is not or only slightly changes the situation.

For this purpose, the conveyor belt 3 by a parallel displacement in particular in

Transfer area 10 deformed. The individual members of the

Spiralglituurturtes laterally, preferably normal to the transport direction 17 relative

shifted to each other.

To Umienkung the conveyor belt 3 to a designed as a sharp transfer edge or transfer knife transfer body 6, a special arrangement of the drive roller is necessary. Spiral liners or other discontinuous metal bands that are suitable for use in the present device have a structure that does not allow a Umienkung to any small Umlenkradien with increased belt tension. In order nevertheless to effect a sharp transfer contour 12 and thus a narrow transfer gap 16, according to the present invention, the transport belt in the starting region 22 of the transfer contour 12 is substantially relieved of tensile stress. This means that in the starting region 22, the tension of the conveyor belt 3 essentially corresponds to the basic tension of the conveyor belt. For example, this basic voltage can be zero, assume positive values, or even assume negative values in the case of a sliding region in the starting region 22. In generic devices that has

Conveyor belt to a base tension, which is constant substantially along the entire conveyor belt 3. When the belt is moving, the tension of the belt continues to rise with each frictional element touching the conveyor belt 3. Thus, after the drive, the belt has the least tension. In the area in front of the drive, the band has the greatest tension. According to the embodiment of FIG. 2, the drive and / or the drive roller 5 is arranged in the area directly in front of the transfer body 6. Directly in front of the transfer body 6 in this context means that the band in the area between the drive roller 5 and the transfer body 6 is substantially free of the tension of the conveyor belt 3 increasing elements. The guiding means 19 do not apply in this case as the tension-increasing Elements, because the tensile stress generated by the friction is less than the tensile stress that would be generated by a gravitational sagging.

Due to the low tensile stress of the belt, in particular in the starting region 22 and / or in the transfer region 10, the lateral displaceability of the

Transport belt 3 improved. In the case of a spiral-twisted belt

Conveyor belt 3, the drive rollers 5 gear-shaped in exemptions of the conveyor belt 3 engaging body. By rotation of these bodies or rollers, on the one hand, the conveyor belt 3 is pulled in the direction of the drive roller 5, and on the other hand, the conveyor belt 3 is pushed by the drive roller 5 in the direction of the transfer area.

The drive rollers 5 can be laterally rigidly connected to the drive shaft of the drive. Thus, a lateral displacement of the conveyor belt 3 in the region of the drive roller 5 is prevented. At a displacement of the conveyor belt 3 in

Transfer area 10 by the positioning device 9, the displacement thus occurs mainly in the area between the drive roller 5 and the transfer contour 12th

However, the drive rollers 5 on the drive shaft and slidably

be arranged. In this case, the lateral position of the conveyor belt 3 by the positioning device 9 in the region of the drive and / or in the region of the drive roller 5 is variable.

According to the invention, however, it is advantageous if the lateral position of the

Conveyor belt 3 is kept constant in the receiving area 15.

Fig. 3 shows a schematic representation of a device according to the invention in a view from above. In this case, a conveyor belt 3 is guided by a plurality of deflection rollers 4 and a transfer body 6. Furthermore, the device has a

Drive roller 5, via which the conveyor belt 3 is driven in the transport direction 17. In the area of the transport surface 2, in particular in the transfer area 10, the conveyor belt 3 is guided around the transfer body 6 for the transfer of the shaped bodies 1. Due to the deflection at the transfer body 6, the transfer contour 12 is formed. Furthermore, the device has a positioning device 9 for positioning the Conveyor belt 3 relative to the machine frame 13, opposite the feed area 15 and / or with respect to the transport surface 2. The

Positioning device 9 is in particular adapted to offset the conveyor belt 3 laterally, to offset the conveyor belt 3 in the transfer area 10 laterally and / or to effect a parallel displacement of the conveyor belt 3. For this purpose, the positioning device 9 positioning means 11. The positioning means 11 are adapted to effect the lateral displacement of the conveyor belt 3. When

Positioning means 11 may be provided for example roller body, roller body, pins or similar elements. In particular, the positioning means 11 can be embodied as elements which are suitable for guiding and / or positioning the conveyor belt 3. For this purpose, two positioning means 11 are provided in the present embodiment. These are provided in the transport direction 17 on both sides of the conveyor belt 3 and guide the conveyor belt along the

Transport direction. Furthermore, the positioning means 1 are movable via the positioning device 9, in particular laterally movable, so that a lateral displacement of the conveyor belt 3 is effected.

Fig. 4 shows a schematic representation of a detail of the positioning device and the device in the transfer area 10. The device is in the central, neutral position. In this case, the conveyor belt 3 is guided substantially straight along the transport direction 17 and not offset.

The device according to the invention comprises a detection device 8 which has one or more detection means 14 for detecting the lateral position of the transport surface 2. The detection means can be used, for example, as optical detection means such as light barriers or laser measuring units, as electromechanical detection means such as microswitches or sensors, and as

Non-contact electrical sensors such as inductive sensors, etc.

be executed. The detection device 8 and the detection means 14 are adapted to determine the lateral position of the transport surface 2 or at least to provide data that allow the positioning device 9 to adjust the lateral positioning of the conveyor belt 3. For this purpose can

For example, be provided a control device. This takes the

Sensor data or the data of the detection means 14 and controls or regulates in Another consequence of the positioning device 9 for the conveyor belt in response to this data. The positioning device comprises, for example, mechanical or

electromechanical actuators 23 adapted to cause movement of the

To cause conveyor belt 3. In the present embodiment, the lateral displacement of the conveyor belt takes place in the transfer area 10 by lateral displacement of the positioning means 11. The positioning means 11 are connected to the

Transfer body 6 connected or coupled. The actuators or the actuator engages on the one hand on the machine frame 13 and on the other hand on the transfer body 6. By length changes of the actuator of the machine frame linear guided transfer body can be moved laterally. About the conveyor belt 3 leading positioning means 11, the conveyor belt 3 is laterally offset in the transfer area. The movement of the actuator or the actuators is dependent in a preferred manner on the movement of the transport surface 2. The coupling is done for example via the control device. Possible actuators 23 are, for example

Linear axes, pneumatic axes, hydraulic axes, pneumatic or

Hydraulic cylinders, servo-actuators, etc.

In the case of mechanical guides, however, a purely mechanical coupling is possible. In this case, the axial movement of the transfer body or the

Conveyor belt also made of a rigid, attached to the transfer body left and right role. This lateral Führungsroilen are employed on the side of the baking belt and are moved by the baking belt.

Fig. 5 shows the same device as Fig. 4, but with laterally offset

Conveyor belt 3. The transport surface 2 is laterally by a certain amount

postponed. By the same amount and the conveyor belt 3 is offset in the transfer area 10. For this purpose, the lateral displacement of the transport surface 2 of the

Detection device 8 and the one or more detection means 14 detected. About a suitable control, the lateral position of the conveyor belt 3 in

Transfer area 10 adapted to the lateral position of the transport surface 2.

Schematically in Fig. 5, the straight position 24 of Fig. 4, in particular whose one side edge is located. The offset position 25 deviates from the course of the straight position 24 to accommodate the lateral displacement of the

To effect transport surface 2. In the present embodiment, the conveyor belt 3 offset between the drive roller 5 and the transfer area 10. This means that the transfer contour 12 of the conveyor belt 3 laterally, based on the

Transport direction 17, is shifted. This displacement is preferably in or along the surface formed between the drive roller 5 and the transfer contour by the conveyor belt. In particular, the conveyor belt 3 is displaced in the region of the transfer contour 12 along the transfer contour 12. Thus, the

Transfer gap 16 held constant between the transport surface 2 and the conveyor belt 3 in the lateral displacement of the conveyor belt 3.

Fig. 6 shows a schematic view for further discussion of the lateral

Displacement. For this purpose, in turn, a conveyor belt 3 is guided around a deflection roller 4, a drive roller 5 and a transfer body 6. Following the transfer body 6, the transfer contour 12 is defined. The conveyor belt 3 is shown in two positions. The straight position 24 corresponds to a position in which the

Conveyor belt is substantially rectilinear in the transport direction. The offset position 25 is shown in dashed lines and corresponds to a position in which the

Transport surface 2 is shifted laterally from the normal position. The conveyor belt 3 is offset in particular laterally between the drive roller 5 and the transfer body 6 or the transfer contour 12. For this purpose, the conveyor belt is moved in the transfer area 10 substantially along the transfer contour 12. By the

Displacement and lateral displacement, the conveyor belt 3 is positioned in the transfer area 10 above the transport surface 2. In lateral change of position of

Transport surface 2 to the offset position 2 'is tracked according to the present invention, the conveyor belt 3. In the receiving area 15, however, the position of the conveyor belt 3 is kept constant. This means that both the

Transport direction 17 and the lateral position of the conveyor belt 3 is kept constant. The transport direction 17 extends in a straight position 24 substantially along a normal plane of the conveyor belt. In offset position 25 and offset conveyor belt 3, the transport direction essentially follows the offset transport direction 17 '.

The transfer area 10 can thus be tracked to the position of the transport surface 2. This tracking is done in a preferred manner continuously, in particular driven by an actuator 23rd The embodiments of FIGS. 1 to 6 are based on the same inventive concept. Alternatives, as for example by different

Embodiments of the transfer body shown in Fig. 1 and Fig. 2, in no way exclude combinations with constructions of other figures. For example, a combination of the embodiments of Figures 1, 3, 4, 5 and 6 is possible. A further combination of embodiments is the embodiment of FIG. 2 with the illustrated embodiments of FIGS. 3, 4, 5 and 6.

The embodiments of Figures 1 and 2 differ essentially by the different embodiment of the transfer body. Features and

Effects of Fig. 1 are therefore also transferable to Fig. 2. The features and modes of operation of FIG. 2 are also applicable to the embodiment of FIG. 1.

Although the basic idea of the invention is not limited to dimensions, exemplary dimensions are given below:

The moldings preferably correspond to limp moldings having a thickness of 1 mm to about 10 mm. The surface of the molded body can be 1 to about 30 cm ² or more. Depending on the size of the molded body, the deflection radius of the

Transfer body about 3 mm to several centimeters. However, the deflection radius is preferably less than 1 cm.

Subsequently, the method according to the invention will be further discussed:

In one embodiment of the method, substantially flexible moldings are conveyed by a rolling out and a piercing device into the receiving region of the device. The transfer to the conveyor of the

Device according to the invention, for example, by deflection of a conveyor belt to a sharp transfer edge. If the shaped body is transferred to the conveyor belt of the device in the receiving area, it will continue to be conveyed in the transport direction. In this case, the shaped body according to the invention happens

Embodiments of Fig. 1 and Fig. 2, the drive roller.

After the drive roller, the conveyor belt is at least according to Figure 2 substantially relieved tensile. The shaped body is subsequently direction Transfer contour further promoted. In the transfer area, the conveyor belt is guided around a transfer body. By the deflection of the conveyor belt on

Transfer body leaves the molding the conveyor belt. In that area in which the shaped body loses the contact with the conveyor belt, the transfer contour is formed, which may be linear or correspond to a surface section.

Between the transfer contour and the transport surface, on which the molded body is transferred, a transfer gap is provided. In the area of this gap, the shape of the body is neither supported by the transport surface nor by the conveyor belt and thus depends freely. In order to avoid damage to the molding, the transfer gap is to be made as small as possible. Subsequently, the molding is transferred to the transport surface. Preferably, the transport surface is formed by a moving baking belt of a baking machine. The baking belt of the baking machine is guided by spatulas, so that a lateral deviation transversely to the

Transport direction occurs.

In order to track the conveyor belt and the moldings of the lateral position of the transport surface, the positioning device according to the invention and the

provided according to the invention detection device. The detection device comprises one or more detection means for detecting the lateral position of the transport surface. The data of the detection device or the lateral position of the transport surface are mechanically or electrically transmitted to a control device or directly to the positioning device. The positioning device comprises one or more actuators for lateral displacement of the conveyor belt in

Transfer area. According to one embodiment, the conveyor belt is in

Transfer area laterally offset. However, the conveyor belt is in the

Recording area kept constant. Thus, the conveyor belt between the receiving area and the drive roller is substantially rectilinear and / or normal to the axes of the pulleys. In the area between the drive roller and the

Transfer contour, the conveyor belt is dynamically offset laterally and tracked the lateral position of the transport surface. As a result, the moldings can always be stored at the desired position of the transport surface. Reference numerals:
