Description

Technical Field

[0001] The present invention relates to an operating method of a palletizing device, which is used to palletize goods (especially bags, preferably bags full of goods) after an unplanned stop (for example, in the case of a defective bag or an emergency stop). The operated palletizing device includes at least one conveying device and at least one stacking platform, the conveying device has at least one conveying component for conveying goods, and the conveying device includes at least one rotating mechanism for rotating goods. The palletizing device also has at least one control device and at least one display device. The present invention also relates to a palletizing device for palletizing goods (especially bags, preferably bags full of goods), wherein the palletizing device includes at least one conveying device and at least one stacking platform, the conveying device has at least one conveying component for conveying goods. The conveying device includes at least one rotating device for rotating goods. The palletizing device also has at least one control device and at least one display device. Background Art

[0002] So-called palletizers are usually connected downstream of packaging systems, for example for filling goods into bags, which stack the filled bags in layers on pallets in individually staggered layers or transfer them to pallets or stack them without pallets. This ensures optimal further transport of the filled bags or other goods (depending on the system).

[0003] In order to palletize the filled bags, a certain number of bags, consisting of a certain number of bags, is arranged in a certain layer in a certain arrangement (i.e. a certain layer arrangement) on a so-called stacking platform and then the bags are stacked on a pallet located below it, for example by pulling open the stacking platform.

[0004] In order to palletize the filled bags, a certain number of bags in a certain arrangement (i.e. a certain layer arrangement) must be arranged on a so-called stacking platform and then the bags are stacked on a pallet underneath, for example by pulling the stacking platform apart.

[0005] Depending on the configuration of the palletizer, for this purpose the bags are transported to the stacking station by means of a conveyor belt, where they are arranged longitudinally or transversely, for example by means of a gripping / turning device, depending on the position in the respective bag layer and the arrangement of the layer. For example, the first row of a layer may include two bags arranged longitudinally, the second row three bags arranged transversely. The next layer is then arranged in the opposite manner so that the layers are combined for stacking.

[0006] To ensure that the automatic stable stacking operates reliably, the correct alignment of the bags on the conveyor line is essential. Problems arise if errors occur or if bags are damaged during transport or if defects are discovered on the way to the stacking station. Unexpected stops can then occur.

[0007] In order to restart the palletizer, the user must, for example, find and remove the defective bag. If the bag is simply removed, the layer arrangement may not be maintained, depending on the position of the bag. However, it is often relatively difficult for the user to recognize whether he can simply remove the defective bag.

[0008] In the event of an unplanned stop or an emergency stop, the bags can often be partially in an undefined state. In this case, the palletizer cannot simply be restarted, but must check whether all bags are in the intended position in the intended orientation. If this is not the case, the user must intervene. However, this type of control is costly and complex. Summary of the invention

[0009] The object of the invention is therefore to support a user of a palletizing device when operating the palletizing device so that operation can be continued efficiently and in particular in an error-free manner, in particular after an unplanned stop of the facility.

[0010] This object is achieved by a method for operating a palletizing device having the features of claim 1 and a palletizing device having the features of claim 15. Preferred further developments of the invention are subject matter of the dependent claims. Further advantages and features of the invention emerge from the general description and the description of the exemplary embodiments.

[0011] The method according to the invention is suitable for operating a palletizing device for palletizing goods, in particular for palletizing bags. In particular, bags filled with goods can therefore be palletized by such a palletizing device, and then the palletizing device can be operated according to the method of the invention. The method according to the invention is therefore performed after the palletizing device stops, in particular after a corresponding unplanned stop or emergency stop, wherein the palletizing device comprises at least one conveying device and at least one stacking platform, which has at least one conveying component for conveying goods. The conveying device comprises at least one rotating device for rotating goods, or at least one rotating device for rotating goods is correspondingly assigned to the conveying device. The palletizing device further comprises at least one control device and at least one display device. According to the invention, when the palletizing device stops, in particular after an unplanned stop or emergency stop, it is displayed to the user on the display device which goods can or need to be removed from the process, and / or which goods cannot or do not need to be removed from the process.

[0012] In particular, unplanned stops or emergency stops may occur when, for example, the load is incorrectly oriented or defective, or when an external emergency stop is triggered, for example by activating a safety device.

[0013] The operating method according to the invention is in particular a method for restarting a palletizing device after an unexpected stop or an emergency stop, respectively, in particular when there are defective bags or an error has occurred.

[0014] The method for operating a palletizing device is particularly suitable for a palletizing device having one or more rotating devices, which are used to appropriately adjust the orientation of the pieces or bags, i.e. longitudinally or transversely, according to a predetermined stacking layer arrangement.

[0015] Preferably, further conveyor belts or intermediate belts or collecting belts etc. are provided in order, for example, to arrange the bags arriving from the packaging device to form a specific layer arrangement, which are then pushed onto a pallet or onto a layer of bags previously pushed onto a pallet.

[0016] For this purpose, in particular a depositing surface is provided between the collecting belt and the stacking table for depositing at least one row of a layer or a complete layer in each case, which is then pushed away as a whole.

[0017] The method according to the invention has many advantages. In the case of an unplanned or planned stop or an emergency stop, usually a defective bag is located on the conveyor line for forming the layer arrangement, or an error occurs, so that the bag is unintentionally turned in the wrong direction by the turning device. In order to enable the user or operator of the palletizing device to quickly and easily identify the error position or which bag is defective and what needs to be done to restart the next operation of the palletizing device, the defective bag is displayed on the display device so that the defective bag can be removed from the process manually, semi-automatically and / or automatically.

[0018] Even in the case of an unplanned stop or an emergency stop, where the bags are in an undefined state, it is possible to show the user in a simple way what he must do with certain bags or whether he can simply remove a bag. In this case, the palletizer cannot simply be restarted, but must check whether all bags are in the intended position in the intended direction. If this is not the case, the user must intervene. However, this type of control is costly and complex.

[0019] The display of the bags is provided by a control device which evaluates the bags on the system in relation to the layer arrangement to be generated and displays via a display device which operations can / can / must be performed and which operations cannot / cannot / must not be performed, so that a restart of the palletizing process is not blocked or is provided accordingly.

[0020] The user can thus directly see, for example, whether individual defective bags can be removed. This ensures that the palletizing system can be operated or restarted particularly efficiently.

[0021] Depending on the position of the damaged bag, it may no longer be possible to maintain or generate the provided layer arrangement when removing the damaged bag if the damaged bag has already been removed. Thus, in particular, in addition to removing the damaged bag, one or more further bags must be removed, or a specific position must be filled again with bags in a specific direction.

[0022] With the method according to the invention, the risk of having to shut down the device again because an image can no longer be created can be significantly reduced or even eliminated. Most importantly, the user can usually put the device into operation again significantly faster.

[0023] The items currently located on the palletizing device are preferably displayed graphically to the user. The overview of the palletizing device is particularly displayed in the form of a schematic diagram so that the user can identify the bags or items on the schematic diagram, particularly as symbols and / or boxes, etc., as they are currently located on the palletizing device or conveyor line, respectively.

[0024] Parts can be displayed, particularly preferably, at least with different displayable attributes, depending on whether they can be removed from the process. Graphical attributes are particularly preferred. For example, the parts can be differentiated by color, hatching, borders, highlighting, background position and / or text, or they can also be highlighted in different ways. In particular, the grouping formation can be displayed so that it can be clearly seen which bags must remain connected and which bags do not have to remain connected.

[0025] In an advantageous configuration, the items are identified accordingly according to a predetermined subsequent position in the layer stack or layer arrangement. Thus, in particular, the bags can be displayed accordingly in a numbered or coded manner so that the user can quickly recognize which position the bag will occupy in the subsequent layer. For example, the bags can be coded or numbered accordingly with three numbers, for example depending on the layer arrangement to be created, wherein the three numbers specify the layer, the row and the bag. For example, a bag can be referred to as 5.2.4, wherein the bag is located in the 5th layer, in the 2nd row of the layer, and wherein the bag is the 4th bag numbered consecutively in the layer arrangement.

[0026] In an advantageous configuration, the user deletes at least one shipment from the display device, wherein the control device adjusts the processing of subsequent shipments accordingly.

[0027] In order to remove a shipment, the user preferably marks the corresponding shipment and then removes it, for example by means of a corresponding symbol and / or by moving the bag or the symbol of the bag accordingly into a trash can. Thus, for example, the user can touch the bag on the display and pull the symbol onto the trash can symbol. The shipment is then actually removed from the process, so that the actual state of the palletizing device again corresponds to the display after the process. The controller or control device then automatically adjusts the process accordingly. For example, the number of the bag can then also be created or adjusted again accordingly.

[0028] In an advantageous configuration, a warning is issued when it is necessary to eliminate a piece that cannot be removed from the process. This clearly points out to the user an operating error which can severely disrupt the subsequent processing of the palletizing device. This is because, depending on the layer arrangement to be created, the corresponding orientation of the bag cannot be maintained when the wrong bag is removed from the infeed or conveyor line.

[0029] The items removed by the user in the control device are preferably removed from the process manually, semi-automatically and / or automatically. Manual removal can, for example, take place manually so that the user removes the bag from the conveyor belt. Semi-automatic removal can, for example, take place by means of a push rod, which pushes the item out of the conveyor belt or conveyor line accordingly. The bag simply falls, for example, on the floor next to the conveyor line and must be removed manually by the user at a certain point. Automatic removal of the item can, for example, take place by means of a robot or also by means of a push rod, wherein the robot can also feed a new bag at the corresponding position. The robot or the push rod can preferably feed the defective bag to a different conveyor belt or the like for removal, depending on the configuration.

[0030] In an advantageous further development, the palletizing device is divided into different workstations, wherein the control device evaluates and / or displays the handling of the items or bags at the individual workstations accordingly. Thus, a particularly clearly structured display of the bags and possible or necessary methods can be displayed accordingly, wherein a particularly efficient method can also be implemented thereby.

[0031] It is particularly preferred to combine a plurality of bags into a group for display, which bags must be treated in the same way. The entire group can then be removed or eliminated accordingly, or left on the conveyor line.

[0032] In an advantageous further development, the user deletes at least one group of items in the display device, in particular after he has marked it, wherein the control device adjusts the processing of the subsequent bags accordingly.

[0033] The planned layer arrangement of the currently processed item or the bag currently located on the conveyor line is preferably displayed, respectively. The user can thus easily control whether the method specified by the control is correct. In addition, he can quickly recognize and check how the replacement bag is placed.

[0034] Preferably, at least one control device is provided which is suitable and designed to check the orientation and / or the state of the cargo. Such a control device can in particular comprise at least one sensor, for example a photodetector, a radar, a camera with corresponding image processing and / or ultrasound. The orientation can be carried out, for example, by image analysis or during activation with the aid of a photodetector. A transversely arranged cargo bag blocks the photodetector for a shorter time than a longitudinally arranged cargo bag. The state can in particular be the integrity of the cargo bag, wherein in particular defects are checked here.

[0035] In an advantageous configuration, the control device checks after the removal of the item whether the removal of the item corresponds to the removal of the item and whether the item fed in as a replacement has been placed in the correct orientation. This prevents errors, for example when a user selects and removes the correct bag in the display device but inadvertently removes the wrong bag from the conveyor belt or places a new bag in the wrong orientation.

[0036] The palletizing device according to the invention is suitable for palletizing goods, in particular bags, in particular after a corresponding unplanned stop or emergency stop. The palletizing device has at least one conveying device and at least one stacking platform, which has at least one conveying element for conveying goods, wherein the conveying device includes at least one rotating device for rotating goods, or wherein at least one rotating device for rotating goods is correspondingly assigned to the conveying device. The palletizing device also includes at least one control device and at least one display device. According to the invention, the control device is suitable and formed to carry out the method as described above.

[0037] The palletizing device according to the invention also has the advantages described in detail above with respect to the method according to the invention.

[0038] The display device preferably comprises at least one touch display. By using the touch display, the user can particularly easily and intuitively mark individual bags and remove them from the process in order to restart the palletizing device. Thus, a bag can be touched with a finger on the touch display and pulled over a trash can symbol, for example, for disposal.

[0039] Preferably, at least one handling device is provided for removing the items or bags, respectively. Such a handling device may preferably comprise at least one robot and / or at least one pusher, in order to remove the items or bags, respectively, from the conveying element.

DETAILED DESCRIPTION

[0048] exist Figure 1 and Figure 2 Detailed description of the invention An exemplary embodiment of a palletizing device 1 according to the invention is shown purely schematically in a perspective view and a top view.

[0049] The palletizing device 1 according to the invention is particularly suitable for arranging the pieces 100 and, in the exemplary embodiment shown here, the bags 200 into a predetermined layer arrangement 17 and transferring them to a pallet 300 , a tray or also in a pallet-free manner.

[0050] In the exemplary embodiment shown here, the bags are filled and sealed in a packaging device 400 which is only shown schematically, and are then fed to the palletizing device 1 via a feed 10 .

[0051] Therefore, in the exemplary embodiment shown here, an elevated feed station 12 is provided, wherein even the entire palletizing device 1 is formed in an elevated manner. For this purpose, the components required for forming the stacking layer 17 of the bags 200 are arranged on a stand 18 in an elevated manner.

[0052] In the exemplary embodiment shown here, the feed section 10 comprises a feed buffer section 11, so that the goods 100 or bags 200 can be continuously and smoothly fed to the palletizing device 1 by the length of the feed section 10 and the conveying speed of the feed section 10. In the exemplary embodiment shown here, the feed buffer section 11 therefore comprises a plurality of gravity rollers 19.

[0053] Downstream of the infeed 10 , the bags 200 are fed to a conveying device 2 which, in the exemplary embodiment shown here, has a conveying element 3 which is formed here as a conveyor belt 20 .

[0054] The bags 200 to be palletized are first conveyed by means of the conveyor belt 20 to the shaping device 9, which is here formed as a flattening belt 21. In particular, dimensionally unstable items 100, such as filled bags 200, are processed in the optional shaping device 9 in order to obtain the most uniform contours and flush surfaces possible. This allows a particularly uniform layer arrangement 17 to be obtained, so that the items 100 or bags 200 can be stacked in a particularly stable manner.

[0055] In the exemplary embodiment shown here, the conveying device 2 further comprises three turning devices 5 , all of which are designed as gripper-type turning stations 6 in the exemplary embodiment shown here.

[0056] The corresponding bag 200 can be brought to each carousel 5, which can then be gripped and turned as required. In this way, the pieces 100 or bags 200 can be arranged on the conveyor 2, respectively, according to the layer arrangement 17 to be produced. In the exemplary embodiment shown here, the layer arrangement 17 is thus processed row by row into two rows.

[0057] In the exemplary embodiment shown here, a collecting belt 13 is arranged immediately downstream of the carousel 5 , by means of which the bags 200 oriented in the desired direction are conveyed row by row towards the stacking station 4 .

[0058] In the exemplary embodiment shown here, the bags oriented to fit the layer arrangement 17 or more precisely the rows of the layer arrangement 17 are therefore first fed to the temporary station 22. For this purpose, a pushing device 14 is also provided, which first pushes the first layer into an intermediate position and then feeds the entire layer arrangement 17 (thus two rows) to the stacking station 4.

[0059] This allows, for example, to lay out a stack 5 with two bags 200 in the longitudinal direction and three bags 200 in the transverse direction, one of which can optionally be rotated 180° in the longitudinal direction so that the head or the foot of the bag always points outwards. The first row of the layer arrangement 17 is then oriented by the rotating device 5 and then conveyed by the collecting belt 13 to the temporary station 22, where the pusher 14 first pushes it into an intermediate position. The fully assembled layer arrangement 17 or the layer of complete bags 200 is then conveyed to the stacking station 4 by the pusher 14.

[0060] In other configurations, the individual rows can also be supplied individually to the stacking station 4 and can therefore only be assembled on the stacking station 4 to form a complete layer arrangement 17 .

[0061] According to the configuration, the pushing device may include one or more slide plates. In particular, a double slide plate or multiple slide plates may also be provided.

[0062] Subsequently, the stacking platform 4 can be displaced or pulled out respectively, so that in the figure the layer of bags 200 is placed on a pallet 300 located below it or is transferred to a pallet 300 respectively. The stacking platform 4 is accordingly in the figure in a retracted position, wherein the lead-out end of the pallet 300 is free. However, it is also possible to transfer the layer arrangement to a pallet or to transfer without a pallet.

[0063] Due to the elevated construction of the palletizing device, the pallet 300 can be arranged below the stacking platform 4, wherein the pallet 300 can be arranged at a position quite close to the stacking platform 4, for example by a dedicated system, such as by a liftable roller conveyor. After the layer of bags 200 is transferred to the pallet 300, the pallet 300 together with the bags 200 can be moved further downwards, so that the distance between the next layer of bags 200 and the stacking platform 4 is the same.

[0064] Alternatively, for example in a 5-pack, the layers are arranged first twice longitudinally and then three times transversely, and in the next layer first three times transversely and then twice longitudinally, to obtain an arrangement of layers connected to each other, which will therefore favour the stack height and transport stability. Alternatively, after each identical layer has been built, the stacking surface or the pallet is respectively rotated 180° to obtain an arrangement of layers connected to each other.

[0065] Figure 3 Purely schematically, a display on a display device 8 of an exemplary embodiment of a palletizing device 1 according to the invention is shown, wherein the displayed view is provided by the control device 7 .

[0066] As can be seen from the illustration, the two layers of bags 200 currently being processed are shown purely schematically as symbols at the top left of the display device 8 , wherein the corresponding layer arrangement 17 is also shown purely schematically.

[0067] In order to give the user a particularly good overview, the individual bags 200 of the individual layers or layer arrangements 15 are numbered consecutively. Thus, the first number represents the layer, the second number represents the row in the layer, and the third number represents the consecutive numbering of the bags 200 in the layer. Thus, in the exemplary embodiment shown here, the bag of the first conveyed layer is numbered 1, and all subsequent bags are numbered consecutively up to 5.

[0068] In addition to the layer arrangement 17 , the palletizing device 1 is also shown in a purely schematic manner on the display device 8 , wherein it is divided here into a plurality of individual workstations 16 for the sake of a clearer overview.

[0069] It is possible to recognize the three transfer stations provided here, which are formed here as gripper transfer stations 6. In the illustrated view, each transfer station 5 contains a bag which is numbered consecutively according to its position in the respective layer arrangement 17, as shown in the upper left corner of the overview of the layer arrangement 17. Thus, the user can clearly assign bags 200 at different points on the conveyor device 2 or the palletizing device 1 to subsequent positions in a layer.

[0070] From the above overview of the layer arrangement of the layers 5 it can be seen that the three turning devices 5 must again turn the bags 5 . 2 . 5 , 5 . 2 . 4 and 5 . 2 . 3 laterally in order to provide them to the conveying device 2 according to the orientation in the layer arrangement 17 .

[0071] Depending on the configuration, the rotary station 5 can be considered as one work station 16. However, each rotary station 5 is considered as a separate work station 16 here.

[0072] The next station 16 shows the collecting belt 13 which, in the exemplary embodiment shown, transports the bags 200 to the side of the temporary table 22 where the complete layer arrangement 17 is assembled and then transported to the stacking station 4. In the display, it can be seen in the case of the station 16 of the stacking station 4 that the complete third layer is ready to be pushed onto the pallet located below it.

[0073] If an unplanned stop of the palletizing device 1 occurs, for example an emergency stop due to a defect in a bag 200, it is often difficult for the user to identify which bag has a problem and what action must be taken for that bag.

[0074] Depending on the configuration, it can be displayed which bag 200 caused the problem. However, depending on the configuration, the user must also identify which bag or bags 200 respectively caused the stop.

[0075] However, according to the invention, it is shown to the user on the display device 8 what he can do with the currently processed bags, or whether he can simply remove these bags from the conveying device 2. Thus, for example, in the exemplary embodiment shown here, it is suggested by hatching that the bag 5.1.2 cannot be removed in any case, at least not without placing the bag again in this position. If this bag is removed without replacing it, problems will arise when completing the layer arrangement 17, because the subsequent bag cannot simply be transferred afterwards. If this bag 200 needs to be removed, it must be replaced by a new bag 200. Otherwise, the layer 5 will not be completed according to the provided layer arrangement 17 and it will have to be discarded in its entirety.

[0076] Figure 3 It is also shown that some bags 200 can be combined to form groups 20, which need to be processed in the same way. In the illustrated view, such combinations to form groups 20 are highlighted by placing them in the background with hatching in the illustrated view. However, other markings or highlights, respectively, may also be used.

[0077] It can be seen that the entire third layer is grouped accordingly into units or groups 20 on the stacking station 4. If a problem occurs here, all bags of this layer need to be handled similarly.

[0078] The same applies to the first row of the fourth layer which is already located on the temporary table 22 and is grouped to form the grouping 20. The second row of the fourth layer which is still located on the collecting belt 13 is also combined to form the grouping 20. Thus, it is possible to simply and clearly display to the user on the display device 8 by means of the control device 7 how certain bags must be handled.

[0079] The control devices 23 may each include at least one sensor 25 according to the configuration, which can be used to automatically identify the corresponding position or orientation of the bag 200.

[0080] In the exemplary embodiment shown, each control device 23 includes a photodetector 26 that can infer direction from the activation time of the bags 200. Bags arranged longitudinally block the photodetector for a longer period of time than bags arranged transversely.

[0081] Furthermore, it is shown here that a trash can symbol is assigned to each station 16 so that, for example in the case where the display unit 8 is formed as a touch display 15, the user can simply click on the bag 200 he wants to remove from the system and can pull it over the trash can symbol with his finger.

[0082] Depending on the configuration, a combined trash can symbol may also be provided, onto which certain bags may be pulled independently of the workstation 16 , for example in the center of the display device 8 .

[0083] Figure 4 2 schematically shows another exemplary embodiment of the palletizing device 1 according to the invention or another exemplary embodiment of the display device 8 of the palletizing device 1 according to the invention, which substantially corresponds to the embodiment according to Figure 3 An exemplary embodiment of .

[0084] and Figure 3 In contrast to the exemplary embodiment shown in , it is shown here that the palletizing device 1 can also have a control device 23, each of which includes at least one camera 27. In the exemplary embodiment shown here, the camera 27 is shown only in a schematic manner in order to show the detection range.

[0085] The camera 27 is used in particular for automatically monitoring the conveying process and the palletizing process in order to be able to detect defects on the bags, for example by means of image recognition.

[0086] It can also be seen that two handling devices 24 are provided here, which can be moved along the conveyor line. Furthermore, it can be seen that in the exemplary embodiment shown, these handling devices 24 include a push rod 28, which is configured to be retractable here. The handling devices 24 of the palletizing device 1 are shown on the display device 8 in order to display the position or state (for example, the push rod 28 is retracted or extended).

[0087] If the bag needs to be removed due to a defect or the like, and if it is removed by the user, for example by pulling it to a trash can, the handling device 24 can be moved next to the bag 200 in the exemplary embodiment shown here and can push the bag down from the conveyor device 2 by means of the push rod 28. The bag then falls next to the conveyor element 3 and can be removed manually by the user later.

[0088] However, depending on the configuration, the handling device 24 may also accordingly comprise a robot or a robotic arm and / or may therefore provide, for example, for removing the bag 200 and sending it to a recycling device.

[0089] Alternatively, another conveying element for removing defective bags may be arranged beside the conveying line, which removes the bags 200 transferred to the conveying element by the push rod 28 or the robot.
