Description

Apparatus and method for reloading cargo units

Besehreibung

The present invention relates to an apparatus and a method for reloading cargo units and in particular for receiving and / or delivering cargo units in a

Charging process.

For example, such a device can be used in the loading of means of transport such as trucks, ships, roller conveyors or rail vehicles or the like to sacks stacked to bag stacks as cargo units on the

Store the loading area of the means of transport targeted.

Such devices have become known in the art. For this purpose, for example, sacks are packed into a sack stack and applied to a pallet. The pallet is then placed on the means of transport together with the bag stack. A disadvantage of such a device is that the pallets must be loaded with and then transported away. So it must be replenished constantly new pallets or recycled in the cycle again by the customer.

It is Z. B. with DE 691 00 158 T2 a device with a gripping and transfer tongs have become known in the stack of flat objects such. B. labels can be automatically gripped and stored in a different position. to

Picking up a pile is exerted from above pressure on the elastic substrate, so that the subsoil yields locally and the lower support plate can be pushed under the label stack. Several grippers are arranged in parallel, allowing you to grasp and move multiple stacks simultaneously, keeping the stacks tightly packed. That works at elastic substrate, since the lower support plate of the gripping pliers can be pushed. A spatially dense arrangement is maintained, since there are no projections of the stacks on the side. A takeover of sack stacks from one

Pallet is thus not possible because of the inclusion of a

Sack stack to unterschiebende support plate gripping tongs could destroy the bottom bags. Thus, sack stacks could be loaded only with pallets, since these are not elastic

Underground offer. A dense arrangement of pallets would be possible, but not a dense arrangement of the sack stack when the pallets project laterally.

It is therefore the object of the present invention to provide a device for receiving and / or dispensing of cargo units and in particular sacks or sack stacks, whereby a dense loading of a means of transport with and

especially without a pallet is possible.

This object is achieved by a device with the

Features of claim 1 and by a device having the features of claim 12, by a device with the

Features of claim 19 and by a method with the

Features of claim 21.

A charging device according to the invention according to claim 1 is used for receiving and / or delivery of charge units in a charging process. The charging device comprises at least one movable charging head. The loading head comprises at least two

Supporting devices each having at least one support part, wherein the support part in each case comprises at least one support surface. The support means are provided and adapted to receive at least two charge units each separately and at least temporarily during the charging process

to support at least from below by means of the support surface of the respective support member. The two separate and side

spaced-apart support means are used for separate recording in each case at least one charge unit. A lateral distance of the two laterally spaced apart Support devices can be changed in a controlled manner in order to be able to set a lateral distance of the two charge units. As a result, two load units can already be aligned side by side directly after transfer to the loading head. The loading head has at least one retaining surface, which is oriented transversely to the support surface of the support part, of a retaining device. The support members of the two support means are movably received on the loading head opposite the retainer to move back the support members

towards the restraint to dispense the charge units from the loading head.

The charging device according to the invention has many advantages. A significant advantage is that two laterally spaced support means are provided which serve to separate receiving each other completely separate cargo units. The load units can be taken from each other with lateral distance and be created by a lateral adjustment of the support means close to each other. It is irrelevant in the invention, whether the pallets are stacked or staggered. Understacking in this context means that the cargo unit is narrower than the pallet and stacks means that the cargo unit protrudes beyond the edge of the pallet. In both cases, several cargo such. For example, sack piles are tightly packed by the two spaced apart laterally

Support devices are moved close to each other after the takeover of cargo, so that a previously existing

lateral distance no longer exists.

At least one retaining device is preferably provided fixedly on the loading head and the support devices can be moved back in their entirety or at least the support parts can be moved back relative to the retaining device. As a result, a relative movement between the cargo unit and to be loaded

Prevents surface so as to avoid damage to the underside of cargo through uneven, sharp-edged surfaces of the surface to be loaded, thereby the Discharge cargo units from the loading head. Such a loading unit is preferably a bag stack, wherein the individual bags are preferably filled with bulk materials.

But it is also possible that the individual bags have fluids or liquids. It is also possible to use a loading device according to the invention when loading sensitive or other piece goods, such as white goods, etc.

The fact that the retaining device holds back the charge unit when moving back the support member, the charging head can be previously accurately positioned and accurately positioned so that the position of the charge unit during or after dispensing or deporting does not change or virtually no change.

Preferably, a guide device for movably receiving the support device and / or for receiving the retraction drive is attached to the retaining device. In such an embodiment, the retaining device is preferably arranged fixed to the charging head and relative to the

Retaining device is movable receiving device

movably arranged on the retaining device. To guide the support means, a running frame or other type of guide means can be arranged on the retaining means and in particular fixed.

At least one support device comprises and preferably at least two support devices preferably comprise two or at least two flat-extended support parts, the tops of which form support surfaces. In this case, a horizontal support width of at least one of the support parts is preferably at least ten times greater than an average vertical thickness of the corresponding support part. The horizontal support width of a support part results from the accumulated support width of all parts or prongs of a support device. For example, a support part of a support device may be scraper-like. It is also possible that a pad part of a

Support device includes a variety of tines, the

provide a total horizontal support surface, the total support width is at least ten times greater than an average vertical thickness of the support member. Preferably, the loading head has two laterally spaced apart

Support devices, the lateral distance can be changed in particular controlled.

For detecting and / or controlling the lateral distance of two support means is preferably at least one

Sensor provided. In particular, the sensor is used to allow a central alignment of two adjacent charge units on the two support means. This ensures that the charge units are reliably and reproducibly placed centrally or appropriately on a loading surface of a means of transport.

Preferably, the two support means of a

Charging head attached to a crossbeam. The crossbeam can also serve to hold or carry the retainer. It is possible and preferred that both support means are provided separately movable on the crossbar. This allows, for example, that a lateral offset of a truck or other means of transport can be compensated. Instead of a crossbeam and other support means can be used.

In preferred embodiments, tilting is the

Support facilities by a small angular dimension to each other possible. For example, a tilting of 3 ° or 5 ° or 10 ° can be made possible. This will help in the processing of

Sack stacks ensure that the bag stacks do not tilt outwards and thus individual bags from the bag stack

slip out. If the two load units are inclined towards each other, then individual bags of the stack of sacks in the upper area are supported against each other.

A lateral slight tilting of the support means can be made possible, for example, by the fact that on the inner side of the support means, the support means in Long holes are guided adjustable in height, while each in the outer region of the support means these on a

Trunnions are arranged stable in height. But it is also possible that each individual receiving device is provided by a certain amount adjustable in height.

This can cause bumps on the back of a

Be balanced means of transport. Also, the height offset, which must be overcome when pushing, can be minimized. It is also possible that each support device in z. B. two slots of different lengths is performed. The inner slots may extend further down than the outer slots.

This will allow the two

Arrange support devices on the bed of a means of transport of different heights, if z. B. unevenness on the truck bed are present, or this is inclined to the horizontal. Through the inner and deeper down extending slots lateral tilting can be achieved during the conversion inwards, so that two sacks of bags can be supported against each other.

The support means may be provided movably on rails or other guide means along the cross-beam by at least one side drive. It is possible that the support means between an outer

Transfer point and an internal transfer position are provided movable.

In preferred embodiments, a length of at least one of the support means in a direction perpendicular to the retaining surface of the retainer is shorter than a

Extension of the cargo unit in this direction. This means that the support parts of at least one and in particular of both support devices terminate below the charge unit and do not project beyond the edge of the charge unit if a charge unit positioned on the support device adjoins the charge unit Retaining surface of the retaining device is present. This ensures that when loading a loading surface of a means of transport, the cargo unit close together and

can be positioned practically without distance from each other.

Preferably, one of the retaining surface of the

Retaining device protruding length of at least one and in particular both support means in a direction perpendicular to the retaining surface of the retainer adjustable. This means that the support device or the support parts of the support device can not only (fully) retracted or extended, but that at least one intermediate position is possible. It is also possible that the end positions are adjustable or adjustable.

Preferably, at least one intermediate position is adjustable. Then, after taking over a loading unit, the corresponding support device can be transferred from the extended position into the slightly or slightly retracted intermediate position. By retracting the support device, a charge unit that may not yet be applied to the retaining surface of the retaining device is moved towards the retaining device, preferably until it bears against it.

Possibly, the control is such that a motor current or a motor torque for moving the support means is detected when moving back. When the cargo unit at the

Retaining device strikes or rests, that rises

Torque and the power required, since the support device is then pulled away under the cargo unit. The detection of an increase in the motor current or the torque can be taken as an opportunity to stop further retraction, or to advance to a predetermined or sensed position. Then the support unit is regularly no longer beyond the cargo unit. Alternatively or additionally, a limitation of the power or the force in the adjustment of the

Charging unit can be provided. It is also possible that the support device is initially extended further than an extension of the cargo unit in the extension direction. The charge units can be detected and measured in total before or else individually during each individual charging process, for example optically from above. In accordance with the measured values or specifications, the support device can then be appropriately returned, so that the front tip of the support device below the

Cargo unit ends and does not project forward.

In other embodiments or in addition, it is also possible that the support means is provided interchangeable. It can be used of different lengths versions, the length of the dimensions of the umzuladenden

Charge units depends.

In all embodiments, it is preferred that at least one sensor for detecting the position of a support device and in particular for detecting the lateral position of a

Support device or the lateral distance of the

Support facilities is provided. In preferred

Embodiments, the loading head is rotatably received on a movable and movable support arm. The support arm consists in particular of at least two pivotable arm members. This can be a height adjustment and a

Longitudinal adjustment of the loading head done.

Furthermore, it is possible that the loading head is provided on a kind of car or the like movable in the longitudinal direction.

It is also possible that the loading head is provided on a transverse bridge in the transverse direction adjustable, for example, to be able to load two different means of transport successively. When a means of transport is loaded, the loading head can be moved to the second means of transport and the loading area of the second means of transport loaded while in the

Meanwhile, another means of transport occupies the position of the first means of transport. For detecting the lateral positions of a support unit, a sensor rod or a sensor plate can be used, which is brought into contact with the charge unit, whereby the

Position of the cargo unit can be determined.

Subsequently, the respective support device on the

Crossbars are moved transversely according to the

to take the desired position.

In all embodiments, it is preferred that the

Support device is associated with a retraction drive to a

Moving back the support device relative to the

Retaining device and thus a levy on the

Support device resting charge unit of the

To allow support device. The support device of

Ladekopfes is moved in the positioning of the loading head.

Therefore, this support device can also be used as a traveling

Pad means are called, since they are in the

Movement of the loading head with moves.

The retraction drive can be at least one linear drive in the form of, for example, a cylinder device, a rack, a spindle or a toothed belt, a double cylinder or

the like. A linear drive allows easy dispensing or stripping of a loading unit from the loading head.

A transfer device according to the invention serves to transfer at least one load unit and in particular of at least two charge units transported in a conveying direction to a loading head. The transfer device comprises at least one carriage with a support surface provided thereon and extending transversely to the support surface

Restraint. The at least one travel carriage is arranged so as to be movable transversely to the conveying direction such that the at least one traveling carriage, at a transverse movement transversely to the conveying direction, is at least partially below the conveying direction

Retainer is movable through to at the

Transverse movement to strip the cargo units. The transfer device according to the invention has many advantages. With the transfer device according to the invention, a transfer of the charge units is made possible to a charging head, wherein the

In particular, on a transport pallet and preferably two transport pallets arranged cargo units are stripped so that in the subsequent loading such

Transport pallet not be loaded with, but remain at the transfer facility and thus the plant is not

leave. Such transport pallets can be used in the field in the circulation.

The load units can be conveyed by means of transport pallets or else directly on a conveyor. The charge units can z. B. be promoted on a roller conveyor as a conveyor. If the carriage for. B.

has at least one roller conveyor, which provides the storage surface available, the cargo units can be arranged on the roller conveyor as a storage area.

The support means may be constructed comb-like in this and in other cases, so that the tines of the comb-like structure of the support means between the rollers

Roller conveyor can be introduced. When stripping the

Loading units in the transverse movement of the carriage or the Verfahrwagen the cargo units are transferred with little or even minimal height offset on the support parts of the support head. It is also possible to position the support device next to the carriage and to move in particular synchronously with during the stripping of the cargo units. This can either by the extension of the support means of the loading head or by a complete process of

Charging done.

A transport pallet in the sense of the present application is in particular an in-house pallet.

The retaining device on the transfer device can also be referred to as a further retaining device. Because the Retaining device on the transfer device stationary relative to the carriage remains, this can

Retaining device may also be referred to as a stationary restraint device. At the transfer device in each case a load unit is delivered by a respective transport pallet and both units are transferred to a loading head.

In a preferred embodiment, the carriage has at least one transportable by a drive conveyor for transporting the transport pallet. Such a drivable conveyor can, for example, as a roller conveyor or

Chain conveyor or the like may be executed.

Preferably, the Verfahrwagen two by one drive and each separately driven

Conveying devices for transporting and positioning two transport pallets in order to position two load units at a defined distance from one another. Here are the

Cargo units positioned in the conveying direction at a defined distance from each other. So it does not matter if the

Pallets are under- or overstacked. Understacking in this context means that the cargo unit is narrower than the pallet and stacks means that the cargo unit protrudes beyond the edge of the pallet.

At least one position sensor is used in particular for detecting a position of a transport pallet and is provided in particular on the conveyor in the conveying direction. For example, the position sensor can detect an incoming transport pallet, and then the conveyor can convey a piece back, so that the transport pallet is arranged in the desired position. This can be done separately for each transport pallet so that a defined simultaneous arrangement of two transport pallets in the defined distance from each other is made possible.

It is also possible that two separate carriages are used, the same time together and / or alternately or sequentially or otherwise controlled to a corresponding positioning of the two separate

To reach the trolley. Particularly preferred is a

Trolley used, can be arranged on the two cargo units and transported. When, in the following, "the

Verfahrwagen "is called, the corresponding applies also for the use of two separate Verfahrwagen.

In preferred embodiments, the retainer is fixed and fixed to a frame. Of the

Verfahrwagen is arranged transversely movable at least between a loading position and an unloading position to the conveying direction. In particular, the carriage is arranged to be movable on the frame. For example, rails or the like may be provided on the frame on which the Verfahrwagen

is arranged movable.

The carriage is particularly preferred on one

Transport surface movable in the conveying direction. The transport surface provides a predefined transport path on which the carriage rolls, in particular supported on wheels, or even glides. The conveying direction of the Verfahrwagens is the transport direction of the Verfahrwagens, preferably not loses its complete circulating transport contact with de transport surface substantially.

The transfer device preferably has at least one adjustable driver, which is intended to immerse in a driver receiving a arranged on the shelf transport pallet to take the transport pallet in a transverse movement of the Verfahrwagens and arranged on the transport pallet loading unit on the

Strip retaining device.

Such an adjustable driver can, for example, by a drive between a drive position and a

Rest position be adjustable. Such a drive can

be carried out by electric motor or via compressed air or Hydraulic or resilient or the like can be operated.

It is also possible that the adjustable driver

for example, is arranged pivotably in the conveying direction, while the carrier is arranged transversely to the conveyor rigidly on the Verfahrwagen. This allows the driver in

Direction of conveyance are pivoted and arranged, for example, in a driver receiving a on the shelf

Submerge the transport pallet when it is being transported. In a transverse movement of the carriage, the carriers take with the transport pallet, so that arranged on the transport pallet loading unit to the retaining device

is stripped off. Following this, the transport pallet can be removed again in the conveying direction and fed, for example, to a circuit.

Preferably, at least one, two, three or at least four drivers are assigned to the carriage. A driver can also invest from the outside to the pallet to fix it on the carriage.

A device according to the invention is used for loading

Charge units, in particular at least two

Cargo units along a transport route to a

Transfer device to be transported and at the

Transfer device to be handed over to at least one loading head. With the loading head, the load units are transferred to a means of transport. The transfer device and / or the charging head each have at least one retaining device on which the charging unit and in particular the at least two charging units can be stripped off for transfer.

In a further development, at least one transport pallet and in particular at least two transport pallets are provided. For such a transport pallet, the Applicant reserves the right to request separate and independent protection. The

Transport pallet has a substantially flat trained pallet body. The pallet body has two from each other spaced and adjacently extending walls, of which at least one wall forms the cover plate and at least one other wall forms the bottom plate. On the cover plate is a support surface for receiving and supporting a

Charging unit provided. Between the cover plate and the

Bottom plate is provided at least one receiving opening for at least one transport member to receive the pallet body and to transport. Preferably, in at least one wall and in particular at least in the bottom plate of

Pallet body provided at least one driver receptacle. The driver receptacle is preferably suitable for this purpose and designed such that an external driver is introduced therein or bears against it in order to be able to fix or move the pallet body in a targeted manner. Even a driver who attacks the outside of the range, is conceivable.

Such a transport pallet can be used, for example, in an internal factory cycle when loading units are to be loaded. If, for example, sack stacks are loaded as load units, the sack stacks can be formed on this transport pallet. The transport pallet can be easily transported within the factory with the stack of sacks thereon.

In this case, the transport pallet, for example, with a

Forklift or the like are detected and transported. If the transport pallet is now transported on a transport conveyor to the transfer device, then the carriers of the transfer device engage in the catch receptacle of the transport pallet and pull the transport pallet with the travel carriage transversely to the transport direction, so that the load unit of the

Transport pallet is deducted.

At the same time the load unit is placed on the support means of a loading head, which was previously introduced into the receiving opening of the transport pallet. This prevents, for example, from a sack stack as a load unit single bags leach out and in the transfer to the Handover device fall down.

As a transport organ z. B. a support part of

Support facility serve.

Preferably, the pallet body consists of the bottom plate, the cover plate and two lateral webs and a central support web, which in particular connect the cover plate with the bottom plate.

Preferably, the plate body has at least one in

at least one direction smooth support surface on the top. This allows for easy sliding of the bag stack on top of the pallet body.

In advantageous embodiments, the support surface

different coefficients of friction in the stripping direction or in the direction of the transverse movement and in the conveying direction. Preferably, the support surface in a longitudinal direction has a higher

Friction coefficients as in an approximately perpendicular to it

extending transverse direction. For example, the

Support surface in the transverse direction corrugations or grooves or grooves or the like, so that when stripping the cargo unit in the transverse direction, a lower resistance or less friction occurs, as in the longitudinal direction, which corresponds to the conveying direction or should correspond.

Preferably, the support surface of the cover plate is smooth

designed to allow a low-friction sliding of the cargo unit on the support surface.

The pallet body preferably consists entirely of a plastic or a metal. But it is also possible that the bearing surface of the pallet body made of a plastic or a metal, while other parts of the pallet body made of other materials.

Particularly preferred are each substantially simultaneously For this purpose, two transport pallets are preferably used, on each of which a cargo unit is arranged.

An inventive method is used for loading

Charge units, in particular at least two

Cargo units along a transport route to a

Transfer device to be transported and at the

Transfer device at least partially passed to at least one loading head. The load units are transferred with the loading head to a means of transport. The

Transfer device and / or the charging head have each

at least one retaining device on which the

Charge unit and in particular two charge units for

Handover be stripped.

The load units can be loaded on transport pallets and transported along a transport route to the transfer device. At the transfer device by means of the retaining device charge units of the

Stripped transport pallet or the conveyor.

In the absence of transport pallets, such. in solid or smooth floors of the cargo units, these can also be stripped off directly.

In all embodiments of the charging head or the

Transfer device or the entire device

preferably each two charge units processed substantially simultaneously. This means that (with one or two) carriages two cargo units are transported practically together. The two load units are handed over to the loading head practically together or simultaneously or in quick succession. The loading head then carries two

Charge units at least temporarily simultaneously. Of the

Loading head then transfers the two load units to a means of transport. The transfer of two load units to the loading head and the transfer of the two load units from the Transfer device to the means of transport takes place simultaneously such that the transfer process of the two load units to the transfer device or the means of transport requires less than 1/3 and in particular 1/4 of the time required on average over all transfer operations to the transfer of the next two charge units passes.

In all embodiments, sensor units may be provided on the device or on its components such as on the charging head, its support parts or on the support arm or on the charging device, with which, where appropriate, distances of the charging head to adjacent walls or surfaces in at least one direction and in particular be detected in all directions. In response to a determined measurement result, the loading head can be correspondingly re-aligned and adjusted in the appropriate dimension or tilted in the longitudinal or transverse direction or about the vertical axis, so that even in operation resulting misalignment of the cargo area recognized and

can be taken into account. Then, the loading head is preferably pivoted about at least one pivot axis so that the

Support parts are again aligned substantially parallel to the ground, so the cargo area or already stored thereon cargo units. Thus, a change in the orientation of the loading surface resulting during the loading can be compensated for.

In a development of the method, a spatial orientation of the charging head is adjusted as a function of the distances detected by the sensor units. As a result, in particular a substantially parallel spatial orientation of the

Charging head to the cargo area reached.

Further advantages and features of the present invention will become apparent from the embodiment, which is explained with reference to the accompanying figures in the following:

FIG. 1 is a highly schematic illustration of a detail of a device 200 in a plan view, which is used for loading

Sack stacks as load units 101 (see Fig. 2) on

Transport means 203, in particular trucks, serves.

The device 200 is shown in a front view in FIG. 2 and in a side view in FIG. 3 and comprises a

Building 202 with several levels. On the lowest floor here two transport means 203 are arranged side by side, on the loading area 204 here successively stack of sacks are deposited as load units 101. The cargo units, which consist here of bag stacks of bags 102, centered on the

Loading surfaces 204 of the truck 203 filed.

Before the start of loading a loading surface 204 is the

Loading area first scanned and recorded three-dimensionally. For this purpose, the car 104 moves together with the bridge 106 in

Longitudinal and transverse directions, so that attached to the carriage 104 scanner (not shown), the cargo area 204 of the transport means 203 or successively all means of transport 203rd

captured in three dimensions. Following this will be from the

Scanning results calculated maximum loading capacity and it is determined the number of cargo units that have space on the bed 204. If the requested number of

Charge units is greater than the possible number, information is output.

Following this, the drive bridge 106 and the carriage 104 travel to the desired first position for loading the loading surface 204 of a transport means 203 with a stack of sacks as

Charging unit 101. The charging head 1 of the device 200 is suitable and is provided, two charge units 101

simultaneously or virtually simultaneously settle on the bed 204 of the transport means 203. The loading head is attached to a loading device 100 and there to a support arm 23, which comprises two or more arm members 24, 25 which are pivotally connected to each other. Via a longitudinal method with the transverse bridge 106 and a transverse method over the carriage 104 and a corresponding movement of the support arm 23, each position of the loading surface 204 of the transport means 203 can be approached.

About a transport path 201 with suitable transport elements, such as a roller conveyor or a chain conveyor, loaded with bag stacks as cargo units 101

Transport pallets 50 via the full pallet feeder 207

transported to the site. Here, two transfer devices 30 are arranged along the transport path 201, since the device provides space for two vehicles 203, which are loaded here in succession. As a result, a first truck can be positioned while the second one is still being loaded, so that a loss of time due to the change of the means of transport is minimized. A

Cargo unit 101 includes in the transport to the

Transfer device 30 preferably a transport pallet 50 and a load positioned thereon, in particular one

Sack stack.

At the transfer devices 30, the bag stack as

Carrying units 101 stripped from the transport pallets 50 so that the empty transport pallets 50 are transported to the removal position 206, where they either automatically

Palletizing be returned to or accepted for example via a forklift 205 and transported away.

Figure 2 shows a front view and rear view of the device 200, wherein the drive bridge 106 is visible in the side view with the charging device 100 disposed thereon.

In Figure 3, three different positions of the loading device 100 are shown, wherein the first and left above pictured position is the transfer position of the conveyor 100, in the loading head 1 of the loading device 100 simultaneously receives two sack stacks as load units 101 at a transfer device 30.

In the middle in Figure 3, the loading device 100 is shown in a longitudinally middle position, while on the right side of Figure 3, the charging device 100 in the

Transfer position 211 is shown, in which the arm members 24 and 25 of the support arm 23 are pivoted against each other, so that the support means 2 of the charging device 100 is located at the level of the loading surface 204 of the transport means 203.

The support arm 23 has a parallelogram construction, so that upon pivoting of the arm members 24, 25, the orientation of the support means 2, 3 remains horizontal. Accordingly, the retaining device 8, which is transverse to the

Support device 2 is aligned, approximately perpendicular

positioned. Optionally, a pivoting of the charging head 1 may be possible.

Figure 4 shows a schematic perspective view of the transfer device 30, wherein a part of the transport path 201 is shown before the actual transfer device 30. The transport path 201 has a conveying device, with which the transported transport pallets 50 are transported with the load units 101 lying thereon in the conveying direction 34

transported and exported to the here as a roller conveyor

Conveyor 37 are handed over.

While the first incoming transport pallet 50 is transported to the conveyor 38, the second

It is also possible to detect a longitudinal distance in the longitudinal direction by the illustrated sensor unit 60 or a separate one

Sensor unit 60.

Due to the fact that such distances z. B. in the vertical and lateral direction are also regularly detected and evaluated during the charging process, a resulting even in operation obliquity of the cargo area 204 can be detected and taken into account. Then, the loading head 1 is pivoted about the pivot axis 59 so that the support members 4, 5 again parallel to the ground (loading area or already stored thereon

Charge units) are aligned. It may in fact result in loading a change in the orientation of the cargo area. If, for example, a truck is loaded, a temporary or even permanent misalignment may result due to different tire pressures or a total compression or loading of cargo units that initially takes place on one side. There are preferably also further sensor units 60 are provided to detect a misalignment in the longitudinal direction. In all cases, sensor units 60 on the

Charging head 1, its support parts 4, 5 or on the support arm 23 or on the charger 100 or the device 200th
