[0001] Palletizing device and method for operating

[0002] Description

[0003] The present invention relates to a method for operating a palletizing device for palletizing piece goods, in particular bags, preferably bags filled with bulk material, after an unplanned stop, such as in the case of defective bags or an emergency stop. The palletizing device which is operated comprises at least one conveyor device with at least one conveyor element for conveying piece goods and at least one storage table, and the conveyor device comprises at least one rotating device for rotating the piece goods. Furthermore, the palletizing device has at least one control device and at least one display device.The present invention also relates to a palletizing device for palletizing piece goods, in particular bags, preferably bags filled with bulk material, wherein the palletizing device comprises at least one conveying device with at least one conveying element for conveying piece goods and at least one storage table. The conveying device comprises at least one rotating device for rotating the piece goods. Furthermore, the palletizing device has at least one control device and at least one display device.

[0004] For example, a so-called palletizer is often installed downstream of packing systems for filling bulk goods into bags. This palletizer stacks the filled bags in staggered layer patterns on pallets, or transfers them to a sheet or even into a stack without pallets. This ensures optimal onward transport of the filled bags or, depending on the system, other general cargo.

[0005] To palletize filled bags, a specific layer of bags consisting of a specific number of bags is arranged in a specific arrangement relative to one another, i.e. with a specific layer pattern, on a so-called lay-down table and then placed on a pallet underneath, e.g. by pulling the lay-down table away.

[0006] Depending on the palletizer's design, the bags are transported to the stacking table via conveyor belts. Depending on their position in the respective bag layer and the layer pattern, the bags are aligned either lengthwise or crosswise, for example, using clamping / rotating devices. For example, a first row of a layer can contain two bags in a lengthwise orientation and a second row with three bags in a crosswise orientation. The next layer is then arranged the other way around, so that the layers are stacked together.

[0007] For automatic and stable stacking to function reliably, the correct alignment of the bags along the conveyor line is essential. This can be problematic if an error occurs, or if a bag breaks during transport, or if a defect is detected on the way to the stacking table. This results in an unplanned stop.

[0008] To restart the palletizer, a user must, for example, locate and remove the defective bag. If only the bag were removed, the layer pattern might not be maintained depending on the bag's position. However, it is often relatively difficult for the user to determine whether they can simply remove a defective bag or not.

[0009] In general, in the event of an unscheduled or emergency stop, some bags may be in an undefined state. In such a situation, the palletizer cannot simply be restarted; instead, it must be checked whether all bags are in a predetermined orientation and position. If this is not the case, a user must intervene. However, the check can sometimes be very time-consuming and complex.

[0010] It is therefore the object of the present invention to support a user of a palletizing device in operating the palletizing device so that operation can be continued efficiently and, in particular, error-free, particularly after an unplanned stop of the system.

[0011] This object is achieved by a method for operating a palletizing device having the features of claim 1 and by a palletizing device having the features of claim 15. Preferred developments of the invention are the subject of the subclaims. Further advantages and features of the present invention will become apparent from the general description and the description of the exemplary embodiment.

[0012] The method according to the invention is suitable for operating a palletizing device for palletizing piece goods, in particular for palletizing sacks. In particular, sacks filled with bulk material can be palletized by such a palletizing device, which can then be operated according to the method according to the invention. The method according to the invention is carried out after a stop of the palletizing device, in particular after an unplanned stop or an emergency stop, wherein the palletizing device comprises at least one conveyor device with at least one conveyor element for conveying piece goods and at least one deposit table. The conveyor device comprises at least one rotating device for rotating the piece goods or at least one rotating device for rotating the piece goods is assigned to the conveyor device. Furthermore, the palletizing device 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 an emergency stop, the display device shows a user which piece goods may or must be removed from the process and / or which piece goods may or must not be removed from the process.

[0013] An unplanned stop or an emergency stop occurs in particular when a piece of cargo is incorrectly oriented or defective, or when an external emergency stop is triggered, for example, by the activation of a safety device.

[0014] The operating method according to the invention is in particular a method for restarting the palletizing device after an unplanned stop or emergency stop, in particular if there is a defective bag or in the event of an error.

[0015] The method for operating a palletizing device can also be used, in particular, with palletizing devices that have one or more rotating devices. The rotating devices are designed to align the orientation of a piece of goods or a bag according to a predetermined layer pattern, i.e., longitudinally or transversely.

[0016] Preferably, further conveyor belts or intermediate belts or collecting belts and the like are also provided in order, for example, to arrange bags arriving from a packing system into a specific layer pattern, which are then pushed onto a pallet or onto a layer of bags previously pushed onto the pallet.

[0017] For this purpose, a depositing surface is provided, in particular, between a collecting belt and the depositing table, for depositing at least one row of a layer or for depositing an entire layer, which is then subsequently pushed off as a whole. The method according to the invention offers many advantages. In the event of an unplanned or unscheduled stop or an emergency stop, there is usually a defective bag on the conveyor line for forming the layer pattern, or an error has occurred such that a bag has been inadvertently turned into the wrong orientation by the turning device. So that a user or operator of the palletizing device can quickly and easily identify the location of the error.which bag is faulty and what the next action is to be to restart the palletizing device, the faulty bag is shown on the display device so that it can be removed from the process, for example manually, semi-automatically and / or automatically.

[0018] Even if bags are in an undefined state in the event of an unscheduled or emergency stop, a user can be easily informed how to handle certain bags or whether or not they can simply remove them. In such a situation, the palletizer cannot simply be restarted; instead, it must be checked whether all bags are in a predetermined orientation and position. If this is not the case, a user must intervene. However, this control process can sometimes be very time-consuming and complex.

[0019] The display of the bags is provided by the control device, which evaluates the bags on the system according to the layer pattern to be generated and shows via the display device which action can / may / must be carried out and which not in order not to prevent the palletizing process from being restarted or to enable it to be restarted.

[0020] For example, a user can immediately see whether or not they are permitted to remove individual defective bags. This ensures particularly efficient operation or restart of the palletizing device.

[0021] Depending on the position of a broken bag, the intended layer pattern may no longer be maintained or created if it were removed. In particular, it may be necessary to remove not only one broken bag, but also another bag or bags, or to refill a specific position with a bag in a specific orientation.

[0022] The risk that a layer pattern can no longer be generated, thus necessitating another shutdown of the system, is significantly reduced or even eliminated by the method according to the invention. Moreover, a user can generally restart the system much more quickly.

[0023] Preferably, the piece goods currently located on the palletizing device are graphically displayed to the user. In particular, an overview of the palletizing device is shown in a schematic representation, so that the user recognizes bags or piece goods, in particular as symbols and / or boxes or the like, in the schematic representation, as they are currently present on the palletizing device or the conveyor line.

[0024] Particularly preferably, the piece goods are displayed with at least one different displayable property depending on whether they may be removed from the process or not. Graphic properties are particularly preferred. For example, a distinction can be made via color, hatching, a border, highlighting, a background, text and / or the piece goods can also be highlighted in another way. In particular, grouping can be displayed so that it is clearly recognizable which bags must remain together and which do not.

[0025] In expedient embodiments, the piece goods are labeled according to a predetermined later position in the layer stack or in the layer pattern. In particular, the bags can be displayed numbered or coded so that a user can quickly recognize which position the bag will take in a later layer. For example, depending on the layer pattern to be created, a bag can be coded or numbered with three digits, where the three digits indicate the layer, the row, and the bag. For example, a bag can be labeled 5.2.4, whereby this bag is intended for the 5th layer, in the 2nd row of the layer and whereby the bag is the 4th bag in the layer numbering.

[0026] In expedient embodiments, a user deletes at least one piece of goods in the display device, whereby the control device adapts the processing of subsequent piece goods accordingly.

[0027] To delete a piece of goods, the user preferably marks the corresponding piece of goods and then deletes it, for example, using a corresponding symbol and / or by moving the bag or the bag symbol to the trash can. For example, a user can touch a bag on a touch display and drag the symbol onto a trash can symbol. The piece of goods is then actually removed from the process, so that the actual status of the palletizing device then corresponds to the edited display. The processing is then automatically adjusted by the controller or control device. For example, the numbering of the bags can then be regenerated or adjusted.

[0028] In practical designs, a warning is issued when a piece of goods is about to be removed from the process. This allows a user to be clearly informed of an operating error that could potentially significantly disrupt the subsequent processing of the palletizing device. Depending on the layer pattern to be created, it may not be possible to maintain the correct orientation of the bags if incorrect bags are removed from the infeed or conveyor line.

[0029] The piece goods deleted by a user in the control device are preferably removed from the process manually, semi-automatically and / or automatically. Manual removal can, for example, be carried out by hand, so that a bag is removed from the belt by a user. Semi-automated removal can, for example, be carried out using a pusher that pushes the piece goods off the conveyor belt or out of the conveyor line. The bag simply falls to the floor next to the conveyor line and must be removed manually by a user at some point. Automatic removal of a piece goods can, for example, be carried out using a robot or a pusher, whereby the robot could then also feed a new bag to the appropriate location. A robot or the pusher can preferably, depending on the design, feed a defective bag to another conveyor belt or the like for removal.

[0030] In advantageous further developments, the palletizing device is divided into different stations, with the handling of the piece goods or bags at each station being evaluated and / or displayed separately by the control system. This allows for a particularly clear display of the bags and the possible or necessary procedures, thereby also enabling a particularly efficient process.

[0031] It is particularly preferable to display several bags grouped together that require the same treatment. This may then make it possible to remove or unload the entire group, or leave it on the conveyor.

[0032] In expedient further developments, a user deletes at least one group of piece goods in the display device, in particular after having marked them, wherein the control device adapts the processing of subsequent bags accordingly.

[0033] Preferably, the planned layer patterns for the currently processed piece goods or the bags currently on the conveyor line are displayed. This allows the user to easily check whether the procedure specified by the control system is correct or not. Furthermore, they can quickly and easily identify and verify how to place a replacement bag.

[0034] Preferably, at least one control device is provided which is suitable and designed to check the orientation and / or the condition of the piece goods. Such a control device can in particular comprise at least one sensor, for example a light barrier, radar, a camera with corresponding image processing and / or ultrasound. The orientation can be carried out, for example, via image analysis or by means of a light barrier via the duration of activation. A transversely aligned bag blocks the light barrier for a shorter time than a lengthwise aligned bag. The condition can in particular be the intactness of a bag, in which case a check for defects is carried out in particular.

[0035] In practical embodiments, the control device checks, after a piece of cargo has been removed, whether the removal of a piece of cargo corresponds to the removal of a piece of cargo and whether a substitute piece of cargo has been placed in the correct orientation. This can prevent errors, for example, if a user selects and deletes the correct bag in the display device, but then accidentally removes the wrong bag from a conveyor belt or places a new bag in the wrong orientation.

[0036] The palletizing device according to the invention is suitable for palletizing piece goods, in particular bags, in particular after an unscheduled stop or emergency. The palletizing device has at least one conveyor device with at least one conveyor element for conveying piece goods and at least one storage table, wherein the conveyor device comprises at least one rotating device for rotating the piece goods or wherein at least one rotating device for rotating the piece goods is assigned to the conveyor device. The palletizing device further comprises at least one control device and at least one display device. According to the invention, the control device is suitable and designed to carry out the method as described above.

[0037] The palletizing device according to the invention also offers the advantages already described above for the method according to the invention.

[0038] The display device preferably comprises at least one touch display. By using a touch display, users can particularly easily and intuitively mark individual bags and remove them from the process so that the palletizing device can be restarted. Bags can be touched with a finger on the touch display and, for example, dragged to a trash can symbol for deletion.

[0039] Preferably, at least one handling device is provided for removing piece goods or bags. Such a handling device can preferably comprise at least one robot and / or at least one pusher for removing a piece of goods or a bag from a conveyor element. Further advantages and features of the present invention will become apparent from the exemplary embodiment, which is explained below with reference to the accompanying figures.

[0040] The figures show:

[0041] Fig. 1 is a purely schematic representation of an embodiment of a palletizing device according to the invention in a perspective view;

[0042] Fig. 2 is a purely schematic representation of an embodiment of a palletizing device according to the invention in a plan view;

[0043] Fig. 3 is a purely schematic representation of a display on the display device of an embodiment of a palletizing device according to the invention; and

[0044] Fig. 4 is a purely schematic representation of a further display on the display device of an embodiment of a palletizing device according to the invention.

[0045] Figures 1 and 2 show, purely schematically, a perspective view and a plan view of an embodiment of a palletizing device 1 according to the invention.

[0046] The palletizing device 1 according to the invention is particularly suitable for arranging piece goods 100 and, in the exemplary embodiment shown here, bags 200, in a predetermined layer pattern 17 and transferring them onto a pallet 300, a sheet or even without pallets.

[0047] In the embodiment shown here, 400 bags are filled and sealed in a packing system that is only indicated schematically and then fed to the palletizing device 1 via an inlet 10.

[0048] In the embodiment shown here, an elevated inlet situation 12 is provided, with the entire palletizing device 1 being designed in an elevated position. For this purpose, the components required for forming a layer pattern 17 of bags 200 are arranged elevated on a type of support structure 18.

[0049] In the embodiment shown here, the inlet 10 comprises an inlet buffer 11, so that a continuous and constant supply of piece goods 100 or bags 200 to the palletizing device 1 can be achieved over the length of the inlet 10 and the transport speed of the inlet 10. In the embodiment shown here, the inlet buffer 11 comprises several gravity rollers 19.

[0050] After the inlet 10, the bags 200 are fed to a conveyor device 2, which in the embodiment shown here has a conveyor element 3, which is designed here as a conveyor belt 20.

[0051] Via this conveyor belt 20, the bags 200 to be palletized are first fed to a forming device 9, which is designed here as a so-called ironing and smoothing belt 21. In this optional forming device 9, particularly non-dimensionally stable items 100, such as filled bags 200, are processed to produce contours and surfaces that are as uniform as possible. This results in a particularly uniform layer pattern 17, so that the items 100 or bags 200 can be stacked particularly securely.

[0052] Furthermore, the conveyor device 2 in the embodiment shown here comprises three rotating devices 5, which in the embodiment shown here are all designed as clamping and rotating stations 6. A bag 200 can be fed to each of these rotating devices 5, which can then be gripped and rotated as needed. This makes it possible to arrange piece goods 100 or bags 200 on the conveyor device 2 according to a layer pattern 17 to be produced. In the embodiment shown here, the layer pattern 17 is prepared line by line in two rows.

[0053] In the embodiment shown, the rotating devices 5 are followed by a collecting belt 13, via which the bags 200 brought into the desired orientation are conveyed line by line towards a depositing table 4.

[0054] In the embodiment shown here, the bags 200 appropriately oriented for a layer pattern 17, or the individual rows for a layer pattern 17, are first fed to an intermediate storage area 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 complete layer pattern 17, i.e., both rows, to the storage table 4.

[0055] For example, a stack of five bags can be laid, in which two bags 200 are provided in a longitudinal orientation and three bags 200 are provided in a transverse orientation, wherein in the longitudinal orientation, one bag is optionally rotated by 180° so that either the head or foot side of the bags always faces outwards. A first row of the layer pattern 17 is then oriented by means of the rotating devices 5 and subsequently transported by means of the collecting belt 13 to the intermediate storage area 22, wherein the pushing device 14 initially moves this to an intermediate position. The fully assembled layer pattern 17 or the complete layer of bags 200 is then fed to the storage table 4 by means of the pushing device 14.

[0056] In other embodiments, the individual lines can also be fed separately to the deposit table 4 and thus only be assembled 17 on the deposit table 4 to form a complete layer image.

[0057] Depending on the design, the sliding device may comprise one or more sliders. In particular, a double slider or a multiple slider may be provided.

[0058] The storage table 4 can then be moved or retracted so that the layer of bags 200 is deposited or transferred onto a pallet 300 located below. The storage table 4 is shown in the figures in the retracted position, in which the passage to the pallet 300 is free. However, the layer pattern can also be transferred onto a sheet or even without a pallet.

[0059] Since a raised structure of the palletizing device 1 is provided, a pallet 300 can be arranged below the storage table 4, whereby, for example, by means of a corresponding system, for example with a raisable and lowerable roller conveyor, the pallet 300 can be arranged relatively close below the storage table 4. After a layer of bags 200 has been transferred onto the pallet 300, the pallet 300 with the bags 200 can then be moved further downwards so that the next layer of bags 200 is at the same distance from the storage table 4.

[0060] For example, in a five-layer stack, the layers are first formed twice lengthwise and three times crosswise, and in the next layer, three times crosswise and twice lengthwise to create an interlocking layer pattern. This contributes to increased stacking and thus transport stability. Alternatively, the storage surface or pallet can be rotated 180° after each layer has been formed in the same way to achieve the interlocking layer pattern.

[0061] Figure 3 shows a diagram displayed purely schematically on the display device 8 of an embodiment of a palletizing device 1 according to the invention, the displayed view being provided by means of the control device 7.

[0062] In the view shown, it can be seen that in the top left of the display device 8, the bags 200 of the two currently processed layers are shown purely schematically as symbols, with the respective layer images 17 being displayed purely schematically.

[0063] To give the user a particularly good overview, the individual 200 bags of the individual layers or layer patterns 15 are numbered consecutively. The first number indicates the layer, the second number indicates the row within the layer, and the third number the consecutive numbering of the 200 bags within the layer. The first bag conveyed in the layer is numbered 1, and all subsequent bags are numbered up to 5 in the example shown here.

[0064] In addition to the layer images 17, the palletizing device 1 is also shown purely schematically on the display device 8, whereby a division into individual stations 16 has been made here for a better overview.

[0065] The three rotation stations provided here can be seen, which are designed as clamping and rotation stations 6. In the view shown, each rotation station 5 contains a bag, which is numbered according to its position in the corresponding layer pattern 17, as shown in the top left of the overview of layer patterns 17. This allows a user to clearly assign a bag 200 on the conveyor 2 or at another location on the palletizing device 1 to its subsequent position in a specific layer.

[0066] As can be seen above in the overview of the layer pattern for layer 5, the three turning devices 5 must turn the bags 5.2.5, 5.2.4 and 5.2.3 transversely once again in order to position them on the conveyor device 2 in accordance with the orientation in the layer pattern 17.

[0067] Depending on the configuration, the turning stations 5 can be treated as one station 16. However, here, each turning station 5 is considered a separate station 16.

[0068] The next station 16 shows the collecting belt 13, which, in the embodiment shown here, conveys the bags 200 next to the intermediate storage area 22, on which the complete layer pattern 17 is assembled before being conveyed to the depositing table 4. The display at station 16 of the depositing table 4 shows that the complete third layer is ready to be pushed onto the pallet below.

[0069] If an unplanned stop of the palletizing device 1 occurs, such as an emergency stop, for example due to the defect of a bag 200, it is usually difficult for a user to recognize which bag is the problem and what should be done with this bag.

[0070] Depending on the configuration, it can be indicated which bag 200 is causing a problem. However, depending on the configuration, the user must also be able to identify which bag(s) caused the stop.

[0071] However, according to the invention, the display device 8 shows a user what they are allowed to do with the bags currently being processed, or whether they are allowed to simply remove these bags from the conveyor device 2 or not. For example, in the exemplary embodiment shown here, the hatching indicates that bag 5.1.2 may not be removed under any circumstances, and certainly not without placing a bag back in its place. If this bag were to be removed without replacement, there would later be a problem when completing the layer pattern 17, since the subsequent bags cannot simply be conveyed on. If this bag 200 has to be removed, it must therefore be replaced with a new bag 200. Otherwise, layer 5 will not be completed according to the specified layer pattern 17 and would have to be completely discarded.

[0072] Figure 3 also shows that certain bags 200 can be grouped into groups 20, which must be treated equally. In the view shown, this grouping into a group 20 is indicated by a hatched background. However, other markings or highlights can also be used.

[0073] It can be seen that the entire third layer on the storage table 4 is grouped as a single unit, or group 20. Should a problem arise here, all bags in the layer would have to be treated equally.

[0074] The same applies to the first row of the fourth layer, which is already on the intermediate storage 22 and grouped into a group 20. The second row of the fourth layer, which is still on the collecting belt 13, is also grouped into a group 20. Thus, the control device 7 can easily and clearly indicate to a user on the display device 8 how certain bags must be handled.

[0075] For automatic detection of the position or orientation of the bags 200, control devices 23 can be provided, which, for example, depending on the design, can each comprise at least one sensor 25.

[0076] In the illustrated embodiment, the control devices 23 each comprise a light barrier 26, which can determine the orientation based on the time of activation by a bag 200. A bag positioned lengthwise blocks the light barrier for longer than a bag positioned transversely.

[0077] Furthermore, it is shown that here each station 16 is assigned a wastepaper basket symbol so that a user, for example in the case of a display unit 8 designed as a touch display 15, can simply click on a bag 200 that he wishes to remove from the system and drag it with his finger onto the wastepaper basket symbol.

[0078] Depending on the design, a common wastepaper basket symbol can also be provided, for example centrally on the display device 8, to which certain bags can be dragged independently of the station 16.

[0079] Figure 4 shows a further exemplary embodiment of a palletizing device 1 according to the invention or of the display devices 8 of a palletizing device 1 according to the invention purely schematically, which essentially corresponds to the exemplary embodiment according to Figure 3.

[0080] In contrast to the embodiment shown in Figure 3, it is shown here that the palletizing device 1 can also have control devices 23, each of which includes at least one camera 27. The cameras 27 are shown purely schematically on the display device in the embodiment shown here in order to indicate the detection range.

[0081] The cameras 27 are used in particular to automatically monitor the conveying process and palletizing so that, for example, defects in bags can be detected using image recognition.

[0082] 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 these handling devices 24, in the illustrated embodiment, comprise a slider 28, which is designed to be extendable. The handling devices 24 of the palletizing device 1 are shown on the display device 8 in order to indicate the position and status (e.g., slider 28 retracted or extended).

[0083] If a bag is to be removed, for example, due to a defect, and is removed by a user, for example, by pulling on the wastepaper basket, the handling device 24 in the embodiment shown here can move next to this bag 200 and push the bag 200 down from the conveyor device 2 by means of the slider 28. The bag then falls next to the conveyor element 3 and can later be removed manually by a user.

[0084] Depending on the design, the handling device 24 can also comprise and / or be provided by a robot or a robot arm, which removes the bag 200 and, for example, sends it for recycling.

[0085] Alternatively, a further conveyor element for removing defective sects can be arranged next to the conveyor line, which transports away the bags 200 which the slide 28 or a robot has conveyed onto this conveyor element.
