- goods such as groceries
- a goods recipient in particular an end consumer
- the goods in an order are delivered to the goods recipient by a delivery service.
- the goods in the order are assembled or picked at a supply warehouse or retail store prior to delivery.
- the goods of the order can be put together in load carriers, for example transport containers.
- the goods of an order can be put together in boxes or carrier bags, which are then placed in the load carriers, for example in the transport containers. This means that several orders can be arranged in one load carrier.
- Filled load carriers are usually pushed into a transport frame.
- a transport system for example a truck, can be loaded with several transport racks loaded with filled load carriers. Using the transport system can now the goods are transported in the load carriers to the goods recipient or to a pick-up station.
- the transport racks with emptied load carriers are brought back to the supply warehouse, where the emptied load carriers have to be unloaded from the transport racks for reuse.
- a transport frame has shelf compartments formed in horizontal rows of shelves arranged one above the other and vertical columns of shelves arranged next to one another.
- the shelves are preferably accessible from a first access side and/or accessible from a second access side.
- the shelves can be loaded, for example, from the first access side and unloaded from the second access side, or vice versa.
- the transport rack comprises a single storage space in a shelf compartment, on which the load carrier is placed, or a multiplicity of storage places arranged one behind the other, on which a plurality of load carriers are placed.
- the transport frame usually includes vertical front uprights, vertical rear uprights, first support profiles between a front upright and a rear upright, second support profiles between the front uprights and second support profiles between the rear uprights.
- the transport racks are usually made of a light metal in order to save transport costs due to the reduced weight of the transport racks, they are, however, susceptible to deformation, which can occur, for example, as a result of transport with the transport system.
- the first and/or second support profiles, the uprights or the like can be damaged, for example kinked, dented, dented or the like.
- the deformations can also lead to warping or twisting of the transport frame. These deformations usually cause an undesirable change in size and/or shape on one or more shelves. The consequence is that the load carriers become wedged or tilted when a deformed transport frame is loaded again and get stuck in the transport frame. In order to avoid this, it is necessary to check the quality of the transport frames before loading in order to detect such deformations and to discard the transport frames if necessary.
- the loading and/or unloading takes place manually, since in this case a deformation of the transport frame can be detected visually by an operator.
- a visual Checking the quality of transport racks is not easy. It is true that warping and torsion can be recognized relatively well by trained personnel. However, this does not mean that a qualified statement can be made about the dimensional accuracy of one or more shelves. Furthermore, new staff must first be trained accordingly.
- US Pat. No. 5,106,259 A discloses a method for automatically loading a transport frame using a loading device.
- the transport frame has pairs of opposite L-shaped angle profiles in stacked shelf levels, which form a shelf for each shelf level.
- load carriers trays
- load carriers trays
- a system for quality control of the transport racks is described, with which an access side of the emptied transport rack is optically scanned and the vertical position of the angle profiles and their alignment with one another is checked in order to determine whether the shelves are suitable for receiving the load carriers (trays).
- the step of checking a quality feature of a transport frame is carried out on the loading device immediately before loading with load carriers (trays).
- An object of the invention is to specify an improved unloading device and an improved method for unloading a transport frame.
- transport racks with damage that would impair proper use of the transport racks should be reliably identified and excluded from (immediate) renewed use.
- a further object of the invention is to specify a loading station, a method for loading a transport frame and a method for unloading and loading a transport frame of the type mentioned at the outset, with which efficiency when loading transport frames can be increased.
- the object of the invention is to specify an order-picking warehouse for storing and order-picking goods of the type mentioned at the outset, which can be operated efficiently.
- the object of the invention is to specify an improved transport frame.
- the first object is achieved according to the invention with an unloading device of the type mentioned at the outset, which unloading device has a monitoring unit for detecting a restraining force, which restraining force acts on the operating unit when the thrust element is extended in an extension direction, with the monitoring unit being designed to generate an error message , when the restraint force reaches a restraint force threshold.
- the quality of a transport rack is checked at the unloading device and not at the loading device, as is known from the prior art. This proves to be an advantage since in the process chain the unloading of a transport frame takes place before this transport frame is loaded and the quality of the transport frame is assessed at the earliest possible point in time.
- a quality feature can relate to the dimensional accuracy of a shelf or multiple shelves.
- the quality feature corresponds to a quality requirement for the transport frame
- a slight deformation on the transport frame such as a slight distortion, a slight twisting of the transport frame, which can lead to a dimensional deviation in one shelf or more of the shelves.
- this dimensional deviation is in a dimension, which has no negative effect on automatic unloading and/or automatic loading of the transport frame, the transport frame still meets the quality requirement.
- the quality feature does not meet a quality requirement for the transport frame, this means that the load carriers cannot be properly ejected from one or some of the shelves and/or cannot be properly pushed into one or some of the shelves.
- a deformation of the transport frame, such as warping or twisting of the transport frame, is to an extent that has a negative effect on automatic unloading and/or automatic loading of the transport frame.
- the extent of the damage to the transport frame can even go so far that automatic unloading and/or automatic loading of the transport frame is no longer possible.
- this transport frame is transported through the loading device, with the transport frame not being loaded in the loading device.
- the transport frame is not fed to a loading device at all. This means that the loading device is not blocked unnecessarily.
- the unloading device can be arranged in particular in an order-picking warehouse, in particular in a supply warehouse and/or in a buffer warehouse, as a result of which the order-picking warehouse can be operated particularly efficiently.
- a threshold value for the restraining force acting on the push element can be defined here, which takes into account a permitted restraining force.
- the permitted restraining force includes, for example, an intrinsic friction of the pusher element when extending, a frictional force between the load carrier to be pushed out and a storage area in the shelf due to the load carrier's own weight and a contact surface.
- An excessive restraining force or the threshold value for the restraining force being reached and/or exceeded can occur in particular if the load carrier to be ejected becomes wedged in the transport frame. This indicates a deformation of the transport frame immediately when unloading the transport frame.
- the restraining force is detected by means of the monitoring unit and, within the meaning of the invention, includes at least an evaluation of whether the restraining force reaches or exceeds a specific value. It is not necessary here for the restraining force to be measured and/or an explicit value for the restraining force to be determined, although this is possible. Thus, the detection of the restraining force can also include the detection of a measured value, which enables the restraining force to be calculated or corresponds to the restraining force.
- the threshold value for the restraining force can be defined, for example, via a maximum extension force with which the pushing element is pushed out. If the load carrier cannot then be pushed out of the shelf even with the maximum ejection force, the restraining force is greater than the specified threshold for the restraining force. The restraining force is thus recorded essentially indirectly by the load carrier getting stuck.
- the transport frame is preferably designed with a rectangular or square base so that they can be arranged side by side to save space. Furthermore, the transport frame has shelves formed in horizontal rows of shelves arranged one above the other and columns of shelves arranged next to one another. The shelves are accessible from a first access side and from a second access side opposite the first access side.
- the transport frame is preferably designed as described at the outset or with reference to FIG. 3 .
- a transport frame can also be provided which comprises a large number of shelves arranged one above the other and/or next to one another, the transport frame having a sensor unit for recording and temporarily storing operating data during manipulation of the transport frame, in particular a vibration sensor or the like. Operating data can thus be recorded and temporarily stored during the manipulation of the transport frame, in particular continuously.
- the temporarily stored operating data can be read out and evaluated with a computer system.
- a Evaluation of the operating data on the computer system can include a comparison with a threshold value, with the quality of the transport frame being checked if the threshold value has been reached and/or exceeded during the manipulation and no check of the quality of the transport frame being carried out if the threshold value is exceeded during of manipulation has not been exceeded.
- the transport frame can be designed as described above or as described below.
- the transport frame comprises a single storage space on which the load carrier can be placed, or a plurality of storage spaces arranged one behind the other, on which a plurality of load carriers are placed one behind the other.
- the shelves of the transport frame are preferably dimensioned so that two load carriers can be arranged one behind the other in a shelf.
- the shelves preferably have a first storage space for a first load carrier and a second storage space for a second load carrier.
- a transport frame forms the shelf compartments exclusively in horizontal rows of shelves arranged one above the other. There is therefore only one single shelf column.
- Each shelf compartment comprises a single storage space on which the load carrier is placed, or a multiplicity of storage spaces arranged one behind the other, on which a plurality of load carriers are placed one behind the other.
- the transport frame comprises shelves lying one above the other in several shelf levels, for example three or four shelves.
- the stacked shelves define a shelf column.
- the transport frame comprises adjacent shelf compartments in a shelf compartment level, for example three shelf compartments.
- the adjacent shelves define a shelf line for each shelf level.
- the transport frame thus has twelve or nine shelves. Each shelf has two shelves arranged one behind the other Parking spaces, on each of which a load carrier can be parked. The transport frame can therefore accommodate 24 or 18 load carriers.
- the transport frame can also be equipped with rollers in the corner areas, so that the transport frame can be moved by an operator and/or by an automated industrial truck, for example an "Autonomous Mobile Robot (AMR)” or “Automated Guided Vehicle (A GV)”. .
- AMR Autonomous Mobile Robot
- a GV Automatic Guided Vehicle
- the transport frame may comprise a lower transport frame and an upper transport frame, which are arranged one above the other and are detachably connected to one another via coupling devices.
- the lower transport frame and upper transport frame are each designed according to the embodiment of the transport frame described above.
- the transport frame is preferably made of a light metal in order to reduce weight and thus save transport costs.
- the charge carriers are preferably formed by reusable charge carriers, in particular charge carriers open at the top, for example containers.
- charge carriers in particular charge carriers open at the top, for example containers.
- the load carriers can also be formed by an insulating container with a lid.
- the pusher element can be extended horizontally relative to the support frame and can thus be brought into a shelf compartment from the first access side of the transport rack in order to move the load carriers placed in the shelf compartment if a load carrier is placed in the shelf compartment, or the load carriers placed one behind the other in the shelf compartment if there are one behind the other in the shelf compartment several load carriers are parked, to be pushed out of the shelf compartment on the second access side of the transport frame.
- An extension length of the sliding element preferably corresponds to at least one depth of a shelf compartment.
- the load carrier placed in the shelf compartment if one load carrier is placed in the shelf compartment, or the load carriers placed one behind the other in the shelf compartment, when several load carriers are placed one behind the other in the shelf compartment, can be completely pushed out of the shelf compartment, thereby ensuring reliable unloading of the transport frame.
- the monitoring unit is designed to generate an error message.
- the error message includes, for example, an optical signal, an acoustic signal and/or an error message output on an electronic output device, for example a tablet computer, computer screen or the like.
- the error message can include or generate an error message signal (control command) with which the operating unit is controlled in order to stop an extension movement of the pushing element.
- an error message can, for example, be designed in such a way that it is not visible to a warehouse worker. Only the result of the error message, namely a stopped unloading process, is visible to the warehouse worker.
- the error message can include an error message signal and the error message output on an electronic output device. In other words, for example, the extension movement of the pushing element is stopped and a message “discharging process aborted” is output at the output device.
- the error message can include a relative movement between the pushing element and a test body described below. This error message can be detected visually or with a sensor system and, if necessary, an error message signal can be generated.
- the second drive device has an electric motor (electric drive motor) and the monitoring unit is designed to detect a motor current and to evaluate the restraining force from the motor current.
- the restraining force can be evaluated in that the monitoring unit detects a progression of the motor current when the thrust element is extended in an extension direction, with the progression of the motor current correlating with a progression of the restraining force. If the motor current reaches or exceeds a specified motor current threshold value, then this also corresponds to exceeding the threshold value for the restraining force.
- the restraining force can thus be evaluated or recorded directly from an analysis of the motor current. An explicit calculation of the restraining force from the motor current is not required for this, although this is possible.
- the restraining force can be calculated from the motor current and compared to the restraining force threshold value in order to determine that the restraining force threshold value has been reached.
- An advantage in a detection of the motor current can be seen in particular in the fact that the Retaining force can be recorded at any time during the extension movement. For example, an increased motor current, which is higher than a basic level but is below the motor current threshold value or below the threshold value for the restraining force, indicates a deformation of the transport frame, which is still permissible in order to enable proper use of the transport frame.
- an operating and/or quality state of the operating unit can be monitored, since a deviation from the base level of the restraining force can indicate wear or damage to the operating unit.
- the pushing element has a front face in the extension direction and a rear face in the extension direction and a support body extending between the front face and the rear face, the front face being designed for pushing out the load carrier.
- the thrust element can be designed essentially in the form of a rod.
- a docking element can be arranged on the front end face, with which the pushing element attaches to the load carrier in order to push it out.
- the docking element forms a docking surface in order to distribute an ejection force and to eject the load carrier evenly.
- the docking element can be designed, for example, as a docking or sliding plate.
- the support body is in particular rod-shaped.
- the operating unit has a test body, which is mounted on the support body and can be pushed into a shelf compartment of the transport frame.
- the restraining force can thus be detected in a simple manner even if no load carrier is arranged in the transport frame.
- the test body enables a check to be made over the entire depth of a shelf compartment. This is also possible if, for example, only one load carrier or no load carrier is arranged in a shelf compartment.
- the test body is adapted to a length dimension, width dimension and/or height dimension of the load carrier.
- the quality check can thus be carried out by checking whether the test body is pushed into a shelf and along this shelf and in particular whether the first storage space and/or the second storage space can be reached with the test body.
- the test body remains, for example stuck in the first storage space of the shelf in the transport frame so that the second storage space cannot be reached, this indicates a strong deformation of the transport frame. It is not possible to use this damaged transport frame again in an unchanged condition.
- Such a transport frame can be supplied to a repair station. It goes without saying that a deformation can also be determined if the test body can only be pushed along the shelf compartment with great difficulty.
- test body has a side part, in particular a side wall, which can be moved orthogonally to the extension direction and which can be moved from a retracted position into an extended position. It is provided here that a width of the test body with the side part in the retracted position is smaller than a width of the test body with the side part in the extended position.
- the width of the test body with the side part in the retracted position is preferably smaller than the width of the load carrier. Specifically, the width of the test body is with the side panel in the retracted position
- the width of the test body with the side part in the extended position is the same size as the width of the load carrier or is greater than the width of the load carrier.
- the width of the test body with the side part in the retracted position is smaller than the width of the load carrier.
- the width of the test body with the side part in the retracted position is smaller than a distance between two vertical uprights of a transport frame, so that the test body can be passed between them.
- test body can thus be inserted or driven into a shelf compartment with the side part in the retracted position between vertical uprights. Inside the shelf, the width of the test body can be adjusted to the width of the load carrier by moving the side panel from the retracted position to the extended position.
- the load carrier can be pushed out of the transport frame are simulated in the width direction orthogonally to the extension direction and a dimensional accuracy of the transport frame is checked in the width direction.
- a restraining force acting on the side part can also be recorded for the movement of the side part in the orthogonal direction, as described above and in detail below for the movement of the test body in the extension direction.
- test body is detachably connected to the pusher element by a coupling unit, the coupling unit being designed in such a way that it releases automatically and allows a relative movement between the pusher element and the test body when the restraining force when the pusher element is extended in the extension direction acts on the test body and the threshold value is reached.
- a load carrier that is positioned on the rear, second storage space in the depth direction of a shelf compartment can still be ejected, even if the test body is already stuck in the front, first storage space in the depth direction of a shelf compartment. Detachment of the test body from the pusher element and the relative movement between the pusher element and the test body represent the error message.
- the test body is preferably arranged in a first position relative to the support body or coupling position when the latter is connected or coupled to the support body. However, if the coupling unit is released, the supporting body can be brought out of the coupling position relative to the test body, in particular into a second relative position.
- the coupling unit can be formed by a first latching element and a second latching element which interacts with the first latching element.
- the first locking element is arranged on the supporting body and the second locking element on the test body, or vice versa.
- the first latching element advantageously comprises a latching projection and the second latching element comprises a latching receptacle into which the latching projection can latch.
- the latching projection and the latching receptacle are of complementary design.
- the first latching element can also comprise a latching element base body, with the latching projection being arranged on the latching element base body.
- the latching projection has flanks which converge at an incline, starting from the latching element base body and in the direction of the latching receptacle.
- the second latching element can also comprise a latching element base body, with the latching receptacle being formed by a latching recess in the latching element base body.
- the latching recess has flanks that diverge in the direction of the latching projection.
- the first latching element is advantageously shaped as a triangular latching projection and the second latching element is shaped as a triangular latching recess.
- the first latching element is preferably spring-mounted, so that it is pressed into the second latching element by a spring force when the test body is coupled to the supporting body.
- the first latching element is moved relative to the second latching element against the action of the spring force and the test body is released from the support body.
- a spring element is arranged between the latching element base body of the first latching element and the supporting body.
- the locking projection is held in the locking recess by the spring force when the test body and the supporting body are coupled.
- the latching projection is in a coupled or latched operating position.
- the locking projection is moved out of the locking recess against the action of the spring force when there is a relative movement between the test body and the supporting body.
- the locking projection is moved into a decoupled or unlocked operating position.
- the threshold value for the restraining force can be set, for example, via the spring force and/or via a slope of the detent projection and a slope of the detent recess.
- the operating unit has an entrainment device which is designed to withdraw the test body from the transport frame.
- This embodiment proves to be advantageous because after decoupling the test body from the support body, the test body is again coupled to the support body simply by retracting the push element in a retraction direction opposite to the extension direction.
- the (coupling) of the test body with the supporting body takes place automatically through the relative movement between the test body and the supporting body and according to the embodiment described above in such a way that that the latching projection of the first latching element and the latching receptacle of the second latching element are brought into engagement with one another.
- the entraining device has a first entraining element which is arranged on the pushing element and can be brought into engagement with the test body when the pushing element is retracted in a retraction direction opposite to the extension direction. If the pushing element has a docking element, for example, this can form a stop, for example, which provides the first driver element. When the pushing element is pulled back, the carrier element docks onto the test body and pulls it out of the transport frame.
- the entrainment device has a second entrainment element, which is arranged on the test body and can be brought into engagement with the first entrainment element when the pushing element is retracted.
- the first driver element and the second driver element are designed as interacting latching elements, analogously to the coupling unit. Provision is particularly preferably made for the driver device to be formed by the coupling.
- the unloading device comprises a sensor system with which the relative movement between the pushing element and the test body can be detected. This means that when the threshold value for the restraining force has been reached or the error message can be automatically detected and, if necessary, a deformed transport frame can be classified as "unsuitable for renewed use”.
- the sensor system is designed in particular to determine whether the test body is in the coupling position.
- the sensor system preferably includes a sensor system, in particular an inductive proximity switch.
- the sensor system may include an electrical circuit configured to be closed (open) when the test body and support body are coupled and open (closed) when the test body and support body have been moved relative to each other.
- electrical contacts that can be brought into contact with one another, for example sliding contacts, can be arranged on the supporting body and on the test body.
- the sensor system can include a light barrier which detects whether the test body is in the coupling position.
- the sensor system can include a camera with which detects the relative movement and this is evaluated, for example, by image recognition.
- test body comprises a test body base frame r and a test body housing, the test body base frame being slidably mounted on the support body in and counter to the extension direction and the test body housing being movably mounted on the test body base frame.
- the test body housing is particularly preferably mounted in a floating manner on the test body base frame via one or more bearing arrangements.
- floating means that the test body housing can be moved relative to the test body base frame in a vertical direction (corresponds to a y-direction) and/or in a horizontal direction running perpendicular to the extension direction (corresponds to an x-direction).
- the test body housing is immovable or fixed relative to the test body base frame in a horizontal direction running parallel to the extension direction (corresponds to a z-direction).
- test body housing has the same degrees of freedom of movement, namely in the x and y direction, as the load carrier.
- the bearing arrangement or bearing arrangements each comprise a centering device and a coupling rod.
- the coupling rod is connected to the test body housing with one of the ends (first end).
- the centering device comprises a first centering element on the test body base frame and a second centering element on the coupling rod.
- the first centering element and the second centering element have a complementary design and can be brought into engagement with one another.
- the first centering element is formed by a conical recess arranged on the test body base frame and the second centering element is formed by a conical projection arranged on the coupling rod.
- the cone-shaped protrusion is provided on another one of the ends (second end) of the connecting rod.
- the conical recess is designed to accommodate the conical projection, so that they form a conical seat.

- the transport rack can be precisely positioned and/or fixed relative to the unloading device by the centering and/or clamping devices, so that the load carriers can be pushed out in a straight line and parallel to a longitudinal stretch of the shelves. This prevents the load carriers from jamming or jamming in the shelves when pushed out.
- a further object is achieved with a picking warehouse of the type mentioned at the outset, the unloading station being designed according to one of the aspects described above and the unloading station and the picking station being connected via an automated load carrier conveyor system which is connected to the transfer unit and through which a load carrier can be transported from the unloading station to the picking station.

Furthermore, the dimensional accuracy of the transport frame can be checked orthogonally to the extension direction.
- the transport frame is precisely aligned, positioned and fixed relative to the operating unit of the unloading device. This avoids unwanted displacements of the transport frame during an unloading process and enables precise detection of the restraining force.

- a length of the second push element essentially corresponds to a length of the load carrier.
- the second pusher element is mounted on the first pusher element in such a way that it can be folded out in order to assume the position of the first load carrier.

- the unloaded transport rack is a completely unloaded transport rack in which all shelves are unoccupied.
- An advantage achieved with the method can be seen in particular in the fact that not only the unloading and loading can be carried out automatically, but also the transport from the unloading station to the loading station. Damage to the transport frame, for example as a result of carelessness or rough transport of the transport frame, can thus also be avoided between the unloading station and the loading station. The method can thus be carried out particularly efficiently.
- the transport frame conveyor technology preferably includes stationary conveyor devices, for example multi-track chain conveyors.
- the transport frame conveyor technology may also include at least one industrial truck that can be moved autonomously, for example an AMR or an AGV.

- the second push element 95b is mounted on the first push element 95a and can be pivoted relative to the first push element 95a about a pivot axis running orthogonally to the extension direction AR.
- a length of the second pusher element 95b essentially corresponds to a length of a load carrier 6.2.
- the second pusher element 95b is mounted on the first pusher element 95a in such a way that it can be folded out in order to assume the position of the first load carrier 6.1.
- the second pusher element 95b thus essentially serves as an extension of the first pusher element 95a.
- the operating unit 89 of the loading device 13 is first moved vertically or in the y-direction along the vertical support structure 93 to a level of that shelf compartment 15 which is to be loaded with a load carrier 6.2 or with a plurality of load carriers 6.2, as is shown in 11a is shown.

- the traction drive is driven by the electric motor 75 .
- the one or more horizontally extensible pushers 60 are attached to the carriage assembly.
- the restraining force can be evaluated in that the monitoring unit detects a course of the motor current when the push element 60 is extended in an extension direction AR, with the course of the motor current correlating with a course of the restraining force. If the motor current reaches or exceeds a specified motor current threshold value, then this also corresponds to exceeding the threshold value for the restraining force.
- the restraining force can thus be evaluated or recorded directly from an analysis of the motor current. If the motor current reaches or exceeds a motor current threshold value or a threshold value for the restraining force, this can indicate impermissible deformation of the transport frame 5.1 or a shelf compartment 15. Such a transport frame 5.1 no longer meets a necessary quality requirement and is classified as “unsuitable for renewed use”.
- the operating unit 28 does not include a test body 61, as is shown in FIG.
- a load carrier 6.1 is pushed out of the shelf compartment 15 by means of the pushing element 60 . If the shelf 15 is deformed and the load carrier 6.1 becomes wedged, the restraining force increases and accordingly also the motor current, which is required for a movement of the pushing element 60 in the extension direction AR. It can be provided, for example, that a Threshold for the motor current is set, which correlates with the threshold for the restraining force.
- the operating unit 28 has a test body 61 which is connected to the supporting body 63 in a fixed or non-detachable manner. If the shelf 15 is severely deformed, the test body 61 becomes wedged in the shelf 15. This is determined by an increase in the motor current. Since the test body 61 is firmly connected to the support body 63 or to the thrust element 60, provision is made here for the movement of the thrust element 60 in the extension direction AR to be stopped when the motor current reaches a specified threshold value for the motor current, which corresponds to the threshold value for the restraining force correlates.
- the test body 61 is detachably coupled to the support body 63 via a coupling unit 69, as described above.
- a coupling unit 69 as described above.
- rubbing and/or wedging of the test body 61 on a deformed transport frame or shelf compartment 15 leads to an increased motor current.
- the test body 61 detaches from the support body 63 as previously described. This results in a sudden drop in the motor current, which indicates that the threshold value has been reached or exceeded.
- the advantage here is that a push-out movement of the pusher element 60 can be continued and, if necessary, load carriers 6.1 can be pushed out of the shelf compartment 15.
- the unloading device 12 is provided with a monitoring unit for detecting a restraining force
- this can be used to carry out a method for unloading and checking a quality or a quality feature on a transport frame 5.1, in particular on a shelf compartment 15, with the steps i) positioning the operating unit 28 with the pusher element 60 in front of one of the shelves 15, in which one or more load carriers 6.1 to be pushed out are located, ii) pushing out the load carrier(s) 6.1 to be pushed out of the shelf compartment 15 by extending the pusher element 60 horizontally, iii) detecting a restraining force by a Monitoring unit, which restraining force acts on the operating unit 28 when the push element 60 is extended in an extension direction AR, and iv) generating an error message when the restraining force reaches a restraining force threshold.
- the transport frame 5.1 comprises a large number of superimposed and/or side-by-side shelves 15, in each of which a load carrier 6.1 to be ejected or in which a plurality of load carriers 6.1 to be ejected are placed, steps i) to iv) are repeated.
- the monitoring unit monitors the pushing out of load carriers 6.1 for each shelf compartment 15 and records the restraining force.
- the method for unloading and checking a quality of a transport frame 5.1 can also include the steps
- the provision of the transport frame 5.1 in the loading station 10 for reloading can include the step
- the method for unloading and checking a quality of a transport frame 5.1 can also include the steps Classifying the transport frame 5.1 as "unsuitable for renewed use” if an error message was generated and the quality feature does not meet a specified quality requirement, and
- An error message is then generated when the restraining force reaches the threshold value when load carriers 6.1 are pushed out of the shelves 15. This means that there is an impermissible deformation, for example on one of the shelves 15, and the transport frame 5.1 cannot be used properly.
- the method for unloading and checking a quality of a transport rack 5.1 can also include the step
- the method for unloading and checking a quality of a transport frame 5.1 can also include the steps
