Description

The present invention relates to an output unit for baked products, in particular for freshly baked baked products, with at least one takeover compartment for taking over the baked products from a feed unit in the dispensing unit, with at least one substantially vertically oriented output tray, as well as with a arranged below the takeover tray output tray for dispensing baked products. The baked products are transportable in the output tray from the transfer tray to the output tray. Furthermore, the invention relates to a production machine for baked products and a method for transporting baked products in an output unit of a production machine.

In a production machine for bakery products, it is often necessary to transport the manufactured products from an oven to an output tray, where the bakery products can then be removed manually. For example, in a combined production and vending machine, the baked products are transported on customer request through an output unit to an output tray for removal by the customer.

The EP 1 577 848 B1 shows an output unit for baked goods, in which the baked goods can be transported from an oven to a removal point. The transport of baked goods is carried out by a column in which several hubs are arranged with horizontal axis of rotation one above the other. Through each turnstile in the column four storage compartments for the products are defined, which are filled one after another with rotation of the turnstile. When the last compartment of the topmost turnstile is filled, the transfer to the underlying turnstile takes place in that the baked product slips on an inclined plane into the next compartment. Are filled in this way all subjects of all hubs, finally, the transfer from the last compartment of the lowest turnstile can be done to a conveyor belt, by means of which the baked goods are removed. The movement of the individual baked goods is thus controlled by the rotation of the turnstiles on a kind of zigzag course. For delicate baked goods as well as for baked goods of various kinds, this device is less suitable.

The EP 0 755 032 B1 shows a vending machine for ice cream or other frozen products. The vending machine has in its interior a variety of stacked, foldable product compartments, which must be filled before selling. If a customer now wants to purchase a product, then the respective lowest product compartment is folded to the side, so that the product located thereon tilts through an output shaft arranged below the product compartments to a removal point located below. The product compartment remains folded to the side so that in the following sales process the next product can be removed from the next higher compartment in the same way. The removal of the products is thus possible only one after the other from bottom to top. This device is not suitable for delicate baked goods

Object of the present invention is therefore to propose an output unit, by means of which even sensitive bakery products can be transported gently. Furthermore, a corresponding production machine and a method for transporting products in a production machine to be proposed.

The object is solved with the features of the independent claims.

An output unit for baked products, in particular for freshly baked baked products, has at least one takeover compartment for taking over the baked products from a feed unit into the dispensing unit, at least one substantially vertically oriented dispensing chute, and an output tray arranged below the pickup tray for dispensing the baked products. The baked products can be transported in the output shaft from the transfer compartment to the delivery compartment. It is proposed that the output shaft is designed as a chute for the purely gravity-driven transport of a single baked product. In this case, the chute has a plurality of case sections arranged on top of one another and a plurality of release devices, wherein each of the case sections is assigned a respective release device, and wherein the case sections can be successively released from top to bottom by the release devices. The baked product can thus be transported gradually falling in the chute.

In a corresponding method for transporting baked products, the baked products are transported in a substantially vertically oriented output shaft from a takeover compartment in which they are transferred to the delivery unit to a delivery compartment located below the transfer compartment. In the output shaft designed as a chute, a single baked product is now transported purely by gravity, wherein the baked product by means of several release devices, which divide the chute into a plurality of stacked case sections, gradually by one fall portion falling from a release device for underlying release device is transported.

Due to the step-by-step transport of one fall section, it is also possible to gently transport even delicate baked products such as puff pastry products over longer distances. Due to the reduced fall height through the individual case sections as well as due to the resulting lower speed of the falling baked goods, damage caused by a rough impact can be avoided. A gentle transport also contributes to the fact that the baked product is transported individually, so that damage is avoided by abutting baking products. Likewise damage by slide elements, hubs or other elements driving the baked products are avoided by the purely gravity-driven transport. The chute can be made comparatively easily with comparatively compact dimensions and constructive. It is also particularly advantageous that can be transported in the same output unit by the purely gravity-driven transport bakery products of different dimensions.

Such an output unit can therefore be used particularly advantageously in a production machine for baked products with a baking unit, with a feed unit arranged downstream of the baking unit and with a dispensing unit arranged downstream of the feed unit.

It is furthermore particularly advantageous in the method according to the invention if the baked product to be transported is transported essentially without rotation. This means that the baked product is transported constant position from one to the next release device and thereby at most slightly tilted out of position during transport, but again assumes its original position upon reaching the next release device. Traces of transport can at best be created at the bottom of the product in this way.

It is also advantageous for the same reason when the baked product is transported in a purely vertical direction through the chute. In a corresponding chute several release devices are arranged in a line one above the other for a purely vertical transport. There are no directional components in the chute. Damage to the baked products by bumping against the walls of the chute are not to be feared. In principle, however, it is also conceivable to arrange such release devices with a slight offset in the horizontal direction to one another in the chute in order to transport the baked product in the horizontal direction by a small distance. In this case, directional components such as slides and the like may be arranged between the release devices.

It is particularly advantageous in a method for transporting baked products when the baked product is completely decelerated at the end of a case section by the underlying release device and the underlying case section is released only after the complete deceleration of the baked product by the respective associated release device. Preferably, the underlying case section is released only after a certain, in particular adjustable, waiting time. As a result, it can be ensured even at different operating conditions and different product dimensions and properties that the baked product is at least delayed and does not fall in one piece through the chute. In principle, however, a controlled, gradually falling transport can already be achieved if the baked product at the end of a case section is merely delayed by the release device below it, for example if it already begins to open when the baked product arrives.

In the case of an output unit, it is furthermore advantageous if the release devices can be transferred from a closed position in which they form a holding floor for the baked product into a release position in which they release the case section assigned to them. By means of such release devices, it is possible not only partially but also completely decelerate a baked product and, as described above, to release the respective next case section only after a defined waiting time.

According to a development of the invention, at least one release device is assigned to the at least one takeover compartment and forms a bottom of the transfer compartment. The baked product can hereby be transported directly from the feed unit in a substantially horizontal direction into the transfer compartment, where it is finally received by the ground-forming release device.

It is particularly advantageous if the at least one releasing device forming the bottom of the at least one transfer compartment is arranged in the chute in such a way that the baked products can be taken over by the delivery unit into the transfer compartment in a horizontal plane. The baked product can thereby already in a particularly gentle way from the feed directly to the release device in the chute be taken over. However, it is also possible to arrange a release device slightly offset from the actual transfer point down if the acquisition is considered uncritical, or this is structurally required. A gentle transport within the output unit is also possible.

According to a particularly advantageous embodiment of the invention, the output unit has a plurality of takeover pockets arranged one above the other in a line, wherein each of the takeover pockets is assigned a respective release device forming a base of the takeover compartment. By means of such an output unit, it is possible to take over different bakery products from different feed lines of the feed unit into the various takeover bins of the output unit and to transport them in the same output unit. The baked products can thus also be supplied to the dispensing unit by feed lines arranged at different heights. It is thus also sufficient to provide only one output tray for different products.

Furthermore, it is advantageous if the release devices each have the same vertical distance from each other. The case sections thus have the same height, so that the baked products controlled in always the same way from one release device can fall to the next. For the same reason, it is also advantageous if the vertical distance of a lowermost release device to a bottom of the output tray corresponds to the vertical distance of the release devices to one another. In particular, in an output unit in which different baked products are transported, the distances of the release devices to each other or to the bottom of the output tray may also be different.

The release devices preferably include two oppositely arranged, in opposite synchronous to each other movable closing elements. This makes it possible to evenly release the cross section of the respective case section, without giving the baked product a directional impulse, as occurs for example in only one, one-way wegklappenden fall flap. Such a release device thus also contributes to a position-constant, rotation-free transport of the baked product. For example, the closing elements are designed as two slide elements movable in the opposite direction away from a center line.

According to a particularly advantageous embodiment of the invention, the release devices comprise as closing elements in each case two substantially in a horizontal plane opposite one another arranged fall flaps. By means of this, a rapid and with regard to the baked product to be transported uniform release of the respective case section is possible. In addition, these only have a small footprint.

In order to ensure the counter-synchronous movement of the two opposing closure elements, in particular drop flaps, it is advantageous if these are connected to one another by means of a synchronizing device, for example a lever mechanism. The synchronous movement can thereby be realized in a structurally simple manner. Alternatively, it is also conceivable to control the two opposing closure elements individually.

According to an advantageous embodiment, such a lever mechanism includes two articulated levers, which are each connected to a fall flap, and a connecting lever, which connects the two lever together.

In addition, it is advantageous if each release device has its own drive, in particular its own electric drive. This allows in a simple way the time-shifted transfer to the release position. Alternatively, it would also be possible to drive several release devices by means of a common drive and to accomplish the successive successive release from top to bottom by means of appropriate scenes or couplings. Such an embodiment may be advantageous if, by means of the chute, a vertical distance between the transfer pocket and the output tray is primarily to be overcome, but no transfer points are arranged at different heights of the chute.

It is also advantageous if the drive of the release devices is connected by means of a transmission, in particular by means of a belt drive, with one of the two lever. As a result, an overload protection for the drive can be realized at the same time. Particularly advantageous is the drive by means of a round belt.

According to a further embodiment of the invention, it is advantageous if a mechanical stop is provided for the opening and / or closing position of the release devices. In this way it can be ensured in each case that the release device is in its correct closed position to keep a baked product safe, or that the release device is in its correct opening position and thus completely releases the chute for the transport of the product. Damage to the baked product any protruding into the chute components or by early release are thereby avoided.

To successively, the plurality of release devices, d. H. time-shifted from top to bottom to transfer to their release position, it is also advantageous if the output unit comprises a control unit, by means of which the release devices are time-controlled in their release position can be transferred. The release devices can be transferred to their release position in predefinable and preferably individually adjustable for each release device time intervals. An adaptation to different baked products or different high case sections is thereby possible in a simple manner.

According to another embodiment of the invention, however, a product sensor can also be provided on each release device, which detects whether a baked product is located on the release device in its closed position. If the sensor detects a baked product, it sends a signal to the drive of the respective release device, which then transfers the release device to its open position.

In addition, it is advantageous if the release devices are each assigned a sensor which detects the position of the respective release device. It can thus be detected for each release device, whether it is in its open position or in its closed position. By means of such sensors, in turn, the drives of the release device can be controlled and the correct successive release can be ensured. Additionally or alternatively, an error message may be issued if, for example, a release device can not be detected in the expected position.

Furthermore, it is advantageous if at least the lowermost release device includes a safety device against engagement from the outside or from the output compartment. The risk of accidents due to moving parts in the dispensing unit is thereby reduced and at the same time the dispensing unit is protected from damage caused by manipulation from the outside.

It is advantageous if the safety device comprises a safety sensor by means of which deviations of the release device from its correct closed position can be detected. Advantageously, a signal is output in case of deviations from the correct closing position, so that, for example, personnel can be alerted.

In a production machine with such a dispensing unit, it is furthermore advantageous if the dispensing unit has at least one pick-up compartment and at least one pick-up compartment is assigned to the feed unit at least one pick-up compartment. The feed line can serve in addition to the feeding of the baked products and the intermediate storage of baked products.

Likewise, it is advantageous if the output unit has a plurality of takeover compartments and each of the takeover compartments is assigned at least one supply line to the supply unit. By means of such a production machine, it is possible to produce different products in a production unit and to transport them away on different feed lines of the feed unit, to store and, if necessary, to take a single baked product from one of the feed lines into a common chute. The production machine can be provided thereby with particularly compact dimensions.

In a method for transporting baked products, it is finally advantageous if the baked products are transported on a product carrier through the chute. It can be transported safely and without damage in one and the same chute both very sensitive products and baked products of different dimensions.

Further advantages of the invention will be described with reference to the embodiments illustrated below:

2 a schematic representation of an output unit in a side view according to a first embodiment;

3 a schematic representation of an output unit in a side view according to a further embodiment;

4 a schematic plan view of a chute of an output unit according to the view arrow A in 1 ;

5 a further schematic plan view corresponding to the view arrow A in 1 ;

6 a schematic side view of an output unit according to the view arrow B of 1 , such as

7 a release device of the output unit of 6 in a detailed view.

1 shows a production machine 1 for baked products 3 , Such as bread rolls, baguettes, croissants, breads and the like, in a schematic overview. The production machine 1 has a baking unit 2 on, in which various baked products 3 can be baked and in a manner not described in more detail here a feeder 4 fed, as by the multiple arrow between the baking unit 2 and the feeder unit 4 indicated. The feeder unit 4 includes according to the present presentation, several feed lines 22 on which the freshly baked baked products 3 cached and to an output unit 5 be transported. The feed lines 22 in the present case each contain a conveyor belt 24 , However, it is also possible instead of a conveyor belt 24 For example, a slightly inclined roller conveyor or low-sensitive bakery products 3 to provide a slide plane. From the output unit 5 can the baked products 3 then from an output tray 7 be removed manually or by machine, as shown by the arrow at the bottom right in the picture.

The output unit 5 now has a chute 6 auf, which according to the present presentation several takeover pockets 8th at which the baked products 3 in the chute 6 can be taken over. The chute 6 is essentially vertically oriented and allows the purely gravity-driven transport, so a largely free-falling transport, a baked product 3 to the below takeover pockets 8th arranged output tray 7 , Also delicate baked goods without damage by the output unit 5 to transport, is now provided that the chute 6 several case sections arranged one above the other 6 ' so that the single baked product 3 gradually by one fall section each 6 ' is transported falling. This is the single baked product 3 at the end of each case section 6 ' delayed or preferably completely decelerated.

To the gradual, free-falling transport of the baked product 3 to allow for each of the case sections 6 ' a release device 9 assigned to the respective case section 6 ' only releases when the baked product 3 the respective release device 9 has reached. Will now be a particular baked product 3 requested, so will the conveyor belt 24 that feeder line 22 on which the desired product is cached, set in motion and a single baked product 3 is in each of the corresponding feed line 22 assigned takeover compartment 8th of the chute 6 accepted. In the present case, this process is shown in dashed lines in the region of the uppermost feed line 22 shown.

For the transport of the baked product 3 become the individual case sections 6 ' now successively from top to bottom through the respectively assigned release devices 9 released as shown by the present six drop arrows in the right area of the 1 is indicated. Finally, the baked product arrives 3 at the end of the lowest case section 6 ' located output tray 7 from which the baked product 3 can be removed. The release devices 9 can in the simplest case, depending on the design and dimensions of the chute 6 as well as the design and dimensions of the baked goods to be transported 3 , a single closing element 10 for closing and releasing the chute 6 include. Preferably, however, two in a horizontal plane opposite each other arranged closing elements 10 like trapdoors 10a or slider elements 10b intended.

The functioning of the release devices 9 will now be based on the 2 and 3 shown. Like that 2 and 3 as well as the 6 removable, are the release devices 9 from a closed position, which is always shown in the figures mentioned in solid lines, in a release position, which is always shown in dashed lines, transferable. The release devices form this 9 in its closed position a holding floor for the baked product 3 out. Only when the release device 9 is transferred to its release position shown in dashed lines, the chute 6 or the respective release device 9 assigned case section 6 ' through the release device 9 released and thus the transport of the baked product 3 free falling allowed.

2 shows an advantageous embodiment of a release device 9 , the two oppositely arranged fall flaps 10a includes. The view of 2 corresponds to the line of sight of the overview of the 1 , The trapdoors 10a are about a pivot axis 23 (recognizable in the 4 and 5 ) pivotable in the region of the side walls of the chute 6 stored. To transfer the trapdoors 10a from the closed position to the release position, these can then synchronously with each other about their respective pivot axis 23 be pivoted (see arrows). Through the synchronous opening movement of the trapdoors 10a becomes a uniform release of the fall section 6 ' achieved, so that the product is imparted no directional impulse, but this purely gravity-driven falls in a purely vertical direction. It is thus a controlled transport of a baked product 3 also possible, if the shaft cross-section is not connected to the baked product 3 is adjusted, even if such an adjustment of the dimensions of the chute 6 to the bakery products 3 course, is advantageous, as based on the 4 and 5 will be explained.

Another advantageous embodiment of a release device 9 is in 3 shown. The 3 gives a view corresponding to the view arrow B of 1 again. It is also in a takeover compartment 8th of the chute 6 a release device 9 arranged, in the present case as closing elements 10 two opposing, in synchronism with each other movable slide elements 10b having. The slide elements 10b are in the horizontal direction from its closed position in its release position shown in dashed lines, as symbolized by corresponding arrows. Also, by means of such an embodiment of the release devices, a uniform release of the chute 6 be reached, which allows a rotation-free, gentle transport of the product in a purely vertical direction.

In the 2 and 3 is just like the production of the 1 the height of the case sections 6 ' largely the same. However, this is not absolutely necessary, such as off 6 evident.

Also shown here is a feed line 22 , each one a takeover compartment 8th assigned. Likewise, however, a takeover compartment could 8th also several feed lines 22 in particular be assigned at the same height offset radially to each other.

Notwithstanding the in 2 and 3 Of course, in a production machine with only one takeover compartment, it could be shown 8th for larger height differences to be overcome even more release facilities 9 one above the other in the chute 6 be arranged.

Furthermore, in the 2 and 3 shown release devices 9 of course, equally advantageous in an output unit 5 with several takeover points 8th or multiple feed lines 22 on top of each other, as in the 1 and 6 shown used.

It is always essential that the baked product 3 largely constant position, ie without rotation about its own axis, and without major tilting movements in the chute 6 can be transported to damage the baked product 3 to avoid.

The position-constant, rotation-free transport of baked products 3 through the chute 6 can still be supported by the fact that the dimensions of the chute 6 to the dimensions of the transported bakery product 3 , are adjusted. In 4 , which is a plan view of a chute 6 shows, it can be seen that the cross section shown the chute 6 a width b that is less than 1.5 times the width B of the baked product to be transported 3 is. In 4 is for example the width b of the chute 6 about 1.3 times the breadth B of the baked product. Likewise, the length l of the chute is 6 , which extends perpendicular to the width b, less than 1.5 times the length L of the transported bakery product 3 , In the present case, for example, the length l of the chute 6 1.4 times the length L of the baked product 3 , It is already sufficient if only one of the two dimensions of the baked product 3 is adjusted. This also makes it possible to bake products 3 different dimensions safely and without rotation in the same chute 6 to transport. The two opposing closing elements 10 can here, as shown here in the longitudinal direction opposite each other or offset by 90 ° in the width direction opposite each other. Likewise, instead of the illustrated trapdoors 10a other closing elements 10 be provided.

After the presentation of the 5 are the dimensions of the cross section of the chute 6 l and b not to the dimensions L and B of the baked product 3 but to the dimensions L 'and B' of a product carrier 21 customized. By means of such product carriers 21 can continue to ensure a damage-free, safe transport even of particularly sensitive baked goods 3 be contributed. Furthermore, such a product carrier allows 21 the safe transport of various products 3 different dimensions. Incidentally, the comments on 4 as well as for the 5 ,

6 shows a side view of an output unit 5 which the view arrow B of 1 equivalent. 7 shows the bottom release device for a better overview 9 the output unit of the 6 in a detailed view. These are schematic views, in which for better understanding the closing elements 10 , Fall Flaps in the present case 10a , are visibly shown, although these are through a side wall 27 of the chute 6 are covered. According to the present presentation, a total of four release devices 9 arranged in a line one above the other, resulting in a particularly gentle, rotation-free transport of the baked products 3 is possible in a purely vertical direction. The release devices 9 are just as in the previous figures each in takeover bins 8th arranged or form the bottom of the takeover pockets 8th out, to each of which by one or more feed lines 22 the baked products 3 be supplied.

To the two trapdoors 10a synchronous to each other in their respective release position, these are each by means of a synchronizer, in this case with a lever mechanism 11 , connected with each other. The lever mechanism 11 For reasons of clarity, it is only at one of the release devices 9 labeled in the middle area and can the 7 to be taken in detail. The lever mechanism 11 includes two linkage levers 12 , each with one of the trapdoors 10a are connected to pivot it from its closed position to its release position, and a connecting lever 13 , the two articulated levers 12 connects together and thereby for the synchronous movement of the two trapdoors 10a provides.

As presented here ( 6 ) is each release device 9 a separate drive 14 assigned to either the fall flap itself, on one of the two lever 12 or the connection lever 13 can work. Is every release device 9 a separate drive 14 assigned, so can the arbitrary removal of a baked product 3 from any feeding line 22 be done in a particularly simple manner, in addition, the closing or releasing the release devices 9 for each release device 9 can be controlled individually. The drive 14 does not necessarily have to be an electric drive 14 be executed; Other drives, for example by means of a pneumatic cylinder, come depending on the location of the production machine 1 also in question.

The drives 14 are present by means of a belt drive 15a with the lever mechanism 13 , in this case directly with the pivot axis 23a one of the trapdoors 10a , connected. By means of such a belt drive 15a is also at the same time an overload protection for the drive 14 feasible because the belt slips when the flaps 10a have reached their respective end position and the drive 14 was not turned off in any other way. It is particularly advantageous, the belt drive 15a with a round belt 16 equip.

Like that 6 and 7 also removable, includes each release device 9 a sensor 18 , which detects whether the release device 9 just in its release position or in its closed position. In the present case, the sensor works 18 for position detection with one of the articulation levers 12 together. Also at 6 is for clarity only a release device 9 labeled. Furthermore, according to the present illustration, both for the closed position of the release device and for the release position of the release device 9 one stop each 17 intended. In the front there is the stop 17 for the closed position on a wall 27 of the chute 6 and acts with an extension 25 of the connecting lever 13 together. The stop 17 for the release position, however, is located on a support 26 , on which also the drive 14 as well as the sensor 18 for position detection of the release device 9 is arranged. Of course, it is equally possible the attack 17 directly inside the chute 6 provide where he then directly with the respective trapdoor 10a interacts.

In the area of the output tray 7 , which is also shown in dashed lines and on the visible wall 27 of the chute 6 is still located on the opposite side, is still a safety device 19 provided, which provides protection against interference from the output tray 7 her as well as against manipulation from the outside causes. This is in the area of the lowest release facility 9 a security sensor 20 arranged, the deviations of the release device 9 recognizes from its correct closed position. In the present case, the safety sensor works 20 with an extension 28 one of the articulation levers 12 together. The safety sensor 19 can be connected, for example, with an optical or audible warning device, which in case of deviations of the lowest release device 9 outputs a warning signal from its correct closed position outside of a regular issue process. Again 6 removable, is still at least the lowest trapdoor pair 10a designed so that it is the cross section of the chute 6 almost completely closes and thus also an intervention protection against interference from the output tray 7 here forms.

Will now be a particular baked product 3 requested, as is already the case 1 described, the respective feed line 22 pressed and the product in a takeover 8th in the output unit 5 to hand over. In the output unit 5 first it rests on the trapdoors 10a the top release device 9 , After a defined period of time, which serves to ensure the safe standstill of the baked product 3 on the release device 9 to ensure, eventually becomes the drive 14 set in motion to the two trapdoors 10a to open. The baked product 3 then falls around the fall section 6 ' on the next underlying trap flap pair 10a the next release device 9 , After a further period of time, which in turn ensures that the baked product 3a sure on the two trapdoors 10a now the second highest release facility 9 is again the second highest release facility 9 transferred to their release position, leaving the baked product 3 then turn on the trapdoors 10a the third release device 9 falls. This continues until the baked product 3 through the lowest case section 6 ' up to the output tray 7 falls.

Again 6 Removable, it is by no means required that the release devices 9 and / or the takeover points 8th equidistant in the chute 6 are arranged. So can individual release devices 9 also have different distances A to each other, about baked products 3 different height H to transport or make an adjustment to design requirements. It is advantageous if the vertical distance A of the release devices 9 to each other or a vertical distance A 'of the lowest release device 9 to the sampling point 7 less than 3 times the height H of the smallest baked product to be transported 3 having. This can also contribute to rotations of the baked product 3 during its transport through the chute 6 to prevent. In particular, if the width b or length l of the chute 6 already closely related to the dimensions L and B of the baked products to be transported 3 or the product carrier 21 However, the distances A and A 'can also be larger. Decisive here is only that the case sections 6 ' not so long that it will damage the baked products 3 upon reaching the closed release devices 9 comes. In addition to the structural conditions and the dimensions of the baked products 3 or product carrier 21 This also depends on what kind of baked products 3 be transported. So are with sensitive bakery products 3 possibly more case sections 6 ' with several release devices 9 required.

The invention is not limited to the illustrated embodiments. Variations within the scope of the claims also fall under the invention.
