Description

The invention relates to a loading device of the type specified in claim 1. Furthermore, the invention relates to a parcel transport vehicle with a loading device.

As more and more online orders are placed these days, the number of packages that are sent to customers via the shipping route is increasing accordingly. This leads to a particularly high volume of traffic, in particular to a particularly high volume of road traffic. Since a respective deliverer in his parcel transport vehicle requires selective access to the respective packages, a storage space of the corresponding parcel transport vehicle cannot be fully used, for example due to a central aisle in the loading space of the parcel transport vehicle. This is because the deliverer goes into this aisle in order to receive the corresponding shipment or the corresponding package in the loading space of the parcel transport vehicle in order to ultimately deliver the package or the shipment to the customer or recipient. There is therefore generally a need to use unused storage space or loading space in transport vehicles particularly efficiently in order to minimize traffic volume due to package transport vehicles.

For example, the DE 10 2013 218 251 A1 a method for the horizontal displacement of article groups or article layers from a first support level of a first conveyor module to a vertically movable second support plane of a second conveyor module immediately downstream of the first conveyor module in a conveying direction, the respectively overridden article group or article position on the second conveyor module by means of a second module Conveyor module is moved horizontally movable support surface in the conveying direction and / or centered on the second conveyor module before or while it is performing a vertical lifting movement.

With this method or with this device for palletizing article groups or layers, an article flow with respect to the first conveyor module is limited to first in first out (first in, first out), as a result of which this method and this device, in particular in the area of package delivery, is only particularly inflexible.

The object of the present invention is to provide a particularly versatile charging device by means of which a cargo space can be used particularly efficiently.

This object is achieved according to the invention by a loading device with the features of claim 1 and by a parcel transport vehicle with the features of claim 10. Advantages and advantageous configurations of the loading device according to the invention are to be regarded as advantages and advantageous configurations of the parcel transport vehicle according to the invention and vice versa. Advantageous refinements with expedient developments of the invention are specified in the remaining claims.

The loading device according to the invention, in particular for a loading space of a parcel transport vehicle, has a transport path on which packages are arranged or can be arranged. The loading device also has a pushing device which has a pushing unit which can be moved between two opposite, lateral ends of the transport track and by means of which packages arranged on the transport track can be displaced along the latter. In particular, the transport track is elongated. The two mutually opposite, lateral ends of the transport path are spaced apart from one another in particular over a longitudinal extent of the transport path. In other words, the transport path extends between the two lateral ends. If at least one package or several packages are arranged on the transport track, for example placed on them, these packages come into direct or direct contact with the push unit when it is moved between the two lateral ends. As a result of a further movement of the pusher unit along the transport path, the corresponding packages are consequently moved along by the pusher unit along the transport path. This means that the packages arranged on the transport path can be moved along the transport path by means of the pushing unit or by means of the pushing device.

In order to design the loading device in such a way that a loading space can be used particularly efficiently, it is provided according to the invention that the push unit comprises a closure element which, at least at one of the two ends, between an operating position in which the closure element delimits the transport path and a loading position , in which the closure element releases the transport path, is adjustable. So the loading device is not limited to an unloading direction of the packages, which is the same as a loading direction of the packages (first in first out: first in, first out). Instead, the charging device can be used both according to the First In First Out principle and according to the Last In First Out principle (last in, first out) without having to adapt the charging device to one of the two principles. By using the thrust unit Packages can be conveyed or conveyed along the transport path to one of the two ends, lateral access to the transport path for loading or unloading the loading device can be omitted. In other words, a user of the loading device, for example a delivery person, does not have to go outside the loading device between the two lateral ends in order to set up a package on the transport path or to remove a package from the loading device. In this way, the loading device can be operated in a particularly space-efficient manner, so that this loading space is used particularly efficiently when the loading device is used in a loading space of a parcel transport vehicle.

It has proven to be particularly advantageous if the pushing device has a locking unit which can be adjusted between a locking position in which the locking element is locked in its operating position and an unlocking position in which the locking element is unlocked from the operating position. This ensures that the closure element, which can also be referred to as a door element, does not accidentally disengage from the locking position.

In order to make the loading device particularly easy to operate, it has proven to be advantageous if the pushing device has a drive unit with at least one pulling means connected to the pushing unit. The drive unit comprises at least one drive element which interacts with the traction means and by means of which the corresponding traction means and consequently the thrust unit can be driven. As a result, manual displacement of the thrust unit can be omitted. For example, it is conceivable that the deliverer operates the loading device from one of the two ends of the transport path, for example in which the deliverer controls the drive unit and / or drives the drive element. The charging device is particularly ergonomic if a force different from a human muscular force can be used or is used to generate a drive torque for the traction means by means of the drive element.

The loading device can be used particularly flexibly if the at least one traction means is endless and the drive unit has respective deflection units at the ends of the transport path, which divide the at least one traction means into an upper run and a lower run. Thus, the pushing device can be made particularly compact and / or low in parts, which in turn is reflected in a particularly low weight of the loading device. Furthermore, the thrust unit can be moved in both directions between the lateral ends by means of the endless traction means, even with only a single drive element. It is to be understood in particular that the invention is not limited to just a single drive element, but that the charging device can comprise more than one drive element.

The at least one traction means can have a textile belt on which a tooth structure is fixed. This means that the belt can be formed, for example, from a woven fabric, a knitted fabric, a braid, etc. and / or a combination of these. In particular, it is provided that threads or fibers are used to manufacture the belt, which are at least partially made of an aramid or comprise an aramid. The tooth structure can have a plurality of individual teeth, a respective individual tooth being, for example, wedge-shaped and extending away from a belt surface. The tooth structure or the individual teeth can be non-positively, positively and / or cohesively connected to the textile belt, so that the individual teeth are arranged equidistantly from one another along the textile belt. A traction device designed in this way has a particularly low mass, so that the loading device as a whole can be designed to be particularly mass-efficient, as a result of which a parcel transport vehicle equipped with the loading device can be operated in a particularly fuel- or energy-efficient and / or low-emission manner.

Furthermore, the textile belt with the tooth structure can be deflected around all three spatial axes, so that even complex traction device profiles would be possible. Due to the use of the plastic fibers described above, which have aramid, the traction means designed in this way is oil, grease, gasoline and benzene-resistant, which makes the traction means particularly suitable for use in a motor vehicle.

In order to move the packages arranged on the transport track particularly efficiently along the transport track by means of the pushing device or by means of the pushing unit, it has proven to be particularly advantageous if the pushing device along the transport track comprises a guide device along which the pushing unit is held perpendicular to the transport track , This ensures that the push unit or the closure element always remains perpendicular to the transport path. This is advantageous in that there is a particularly low risk that the pusher unit will be deflected from the vertical position by means of a package placed on the transport track, as a result of which the package in question would not be carried as intended by means of the pusher unit.

Particularly when the loading device is used in a parcel transport vehicle, effective securing of the load of the packages transported in the parcel transport vehicle is advantageous and is required by law. For this purpose, the loading device along the transport path can have a delimitation device which, together with the transport path, defines a transport channel, an upper element of the delimitation device being spaced apart from the transport path and side elements of the delimitation device spaced apart from one another in mirror image perpendicularly adjoining opposite longitudinal edges of the transport path and longitudinal edges of the upper element. To put it more simply, the transport path and the delimiting device form an at least essentially cuboid hollow prism with one another. Here, the transport path determines at least a portion of an inner surface of the cuboid and hollow prism.

The packages arranged in the interior of the transport channel defined by the rectangular hollow prism are secured against falling out of the loading device due to the limiting device. Along the longitudinal direction of the loading device or the transport track, these packages are secured on the one hand by the pusher unit and on the other hand by a stop element delimiting the corresponding other end. The corresponding packages between the push unit and the stop element can be secured or secured in a form-fitting manner.

The loading device can also have a sensor unit, by means of which it can be determined on at least one of the lateral ends of the transport path whether the at least one package is conveyed to a removal position. For example, it can be provided that the sensor unit provides a sensor value that characterizes that the at least one package has arrived at the removal position. This sensor value can, for example, be made available to a display device which provides the deliverer with appropriate information, so that the deliverer can be informed or informed accordingly that the corresponding package at the removal position, for example at one of the two ends, is ready for removal and further delivery. Alternatively or additionally, it is conceivable that the sensor value is made available to a control device of the loading device, which is designed to control the pushing device, for example to move the pushing unit. In this context, it can be provided that the control device, as soon as the sensor signal described above is provided, ends further movement of the thrust unit and / or does not begin. This prevents a package from being pushed beyond one of the two ends of the transport path by the pusher unit and falling out of the loading device.

Furthermore, the charging device can have a further sensor unit which is designed differently from the sensor unit described above. This further sensor unit can be used to determine at least one of the lateral ends of the transport path as to whether the thrust unit is moved to an end position. The loading device is thus particularly efficiently protected against damage which could occur if the drive unit continues to act on the thrust unit, although it has reached its extreme end position, in particular at one of the two ends of the transport path. This is because the further sensor unit can provide a sensor signal which characterizes that the thrust unit is moved to the end position. This sensor signal can be made available to the deliverer and / or the control device, in particular analogously to the above description, as a result of which it is effectively prevented that the thrust unit arranged in the end position is further undesirably driven.

The invention further relates to a parcel transport vehicle with at least one, in particular previously described loading device. As is known, the parcel transport vehicle has a loading space which is used particularly efficiently in that at least one loading device is / is used in the loading space. In particular, a large number of loading devices can be used in the loading space of the parcel transport vehicle, the individual loading device being fixed to one another in a force-fitting and / or form-fitting manner and / or in the loading space. Since the loading space of the transport vehicle equipped with the loading device according to the invention is used particularly efficiently, individual packages or consignments can be delivered to a customer with particularly low emissions.

Further advantages, features and details of the invention result from the following description of a preferred exemplary embodiment and from the drawing. The features and combinations of features mentioned above in the description and the features and combinations of features mentioned below in the description of the figures and / or shown alone in the figures can be used not only in the respectively specified combination but also in other combinations or on their own, without the scope of Leaving invention.

1 shows a perspective view of a loading device 1 which is a transport track 2 on which packages (only in 10 shown and with 58 referred to) are arranged or can be arranged. The transport track 2 extends between two opposite, lateral ends 3 . 4 the transport track 2 along a transport direction 5 , That means the direction of transport 5 parallel to the transport track 2 or parallel to a longitudinal extension of the transport path 2 runs.

The charger 1 also has a pusher 6 on, which in turn is a thrust unit 7 has that between the two ends 3 . 4 along the transport track 2 or along the transport direction 5 is movable. In 1 is the thrust unit 7 shown how this is arranged in a first end position A. The end position A is one of the two ends 3 . 4 , here the end 4 , associated with the end 4 in this example the end position A certainly. A second end position is accordingly B provided which of the first end position A along the transport track 2 or along the transport direction 5 over the longitudinal extent of the transport track 2 from the first end position A is spaced. The end position B is analogous to the end position A , the corresponding other of the ends 3 . 4 , here the end 3 , assigned so that the end 3 the end position B certainly. As a result, the thrust unit 7 between the two end positions A . B movable. Is one package or there are several packages on the transport track 2 arranged, for example placed on these, these packages are by means of the pusher 6 , in particular by means of the thrust unit 7 , along the transport track 2 or along the transport direction 5 displaceable by moving the thrust unit 7 this comes into direct contact with the corresponding packages or with the corresponding package and when the thrust unit is moved further 7 this the package or packages over the transport track 2 pushes. In the present example are on the transport track 2 set up packages by means of the push unit 7 starting from the end 4 towards the end 3 movable there. For this purpose it is provided that the packages between a respective end 3 . 4 and the thrust unit 7 are arranged.

A parcel transport vehicle 8th (please refer 10 ) has a hold 9 in which the loading device 1 can be arranged or arranged. It is particularly preferred if in the hold 9 a variety of loading equipment 1 is arranged, the respective loading devices 1 are arranged one above the other and / or next to one another. In particular, the respective loading devices limit 1 right next to each other so that the cargo space 9 is used particularly efficiently. Particular attention should be paid to that in the hold 9 no aisle can be kept clear, as by means of the respective thrust units 7 at one of the two ends 3 . 4 the packages are conveyable. In the present example, that's the end 3 Load opening opening end.

In particular, it is provided that the loading device 1 Non-destructively detachable in the hold 9 can be secured or secured. Accordingly, it is provided that the loading device 1 outside the hold 9 is loaded with packages, which by means of the package transport vehicle 8th Are to be delivered to customers. This is advantageous in that the parcel transport vehicle is at a standstill 8th for loading the same is particularly short, which means that the parcel transport vehicle 8th can be used particularly efficiently.

To the charger 1 The push unit has a particularly flexible design 7 a closure element 10 between an operating position (see 2 ) and a loading position (see 3 ) is adjustable. In 1 is the closure element 10 arranged in its operating position, the closure element 10 the transport track 2 limited. Is the closure element 10 arranged in the loading position, gives the closure element 10 the transport track is clear.

To avoid being on the conveyor 2 erected packages off the ends 3 . 4 from the transport track 2 fall down, the charger points 1 along the transport track 2 a limiting device 11 on which along with the transport track 2 a transport channel 12 Are defined. For this is an upper element 13 the limiting device 11 the transport track 2 opposite and spaced from it, so that even when the loading device rotates 1 around the direction of transport 5 , for example in a traffic accident of the parcel transport vehicle 8th , the packages within the transport channel 12 are held. Furthermore, the limiting device 11 Side elements spaced apart in mirror image 14 on which is perpendicular to the transport path 2 stand and each on opposite longitudinal edges 15 the transport track 2 adjoin. Furthermore, the side elements limit 14 perpendicular to the corresponding longitudinal edges 16 of the top element 13 on. In this way, a cuboid prism is formed, which extends along the longitudinal extent of the transport channel 12 has a rectangular, in particular square, cross section. An interior of the cuboid prism is hollow because the cuboid prism is completely from the transport channel 12 is permeated. Consequently, on the transport track 2 erected packages inside the transport channel 12 arranged, and are by means of the thrust unit 7 within the transport channel 12 along the direction of transport 5 movable.

2 shows the perspective view of the thrust unit 7 with the closure element arranged in the operating position 10 , 3 shows the perspective view of the thrust unit 7 with the closure element arranged in the loading position 10 , To avoid the closure element 10 unintentionally disengages from the operating position, the charging device 1 , especially the pusher 6 , a locking unit 17 on, which between a locking position - as in 2 shown - and an unlocked position - as in 3 shown - is adjustable. The locking unit holds in the locking position 17 the closure element in its operating position. Furthermore, the locking unit arranged in the locking position enables 17 if the closure element 10 is disengaged from its operating position that the closure element 10 is adjusted into the operating position and is releasably held in the operating position. The locking element is in the unlocked position 10 released so that the closure element 10 in the unlocked position of the locking unit 17 is adjustable from the operating position, in particular into the loading position.

The locking unit 17 has a locking latch 18 on which is an extension 19 of the closure element 10 reaches behind in the locked state. The process 19 and the locking latch 18 are in the locked state in the middle of an edge 20 of the closure element 10 arranged. To inadvertently unlock the extension 19 to avoid, the locking unit 17 a lockout unit 21 by means of which the locking latch 18 can be locked in the locking position. For example, a bolt 22 under tensioning a spring element from one with the bolt 22 corresponding bolt receptacle of the locking latch 18 disengage so that the locking latch 18 from the extension 19 is unlockable. Furthermore, the locking unit 21 at least one securing element 23 , in the present case two securing elements 23 , by means of which the closure element 10 can be secured in its operating position. The securing elements 23 can be analogous to the bolt 22 be formed with the securing elements 23 in that from the bolt 22 distinguish that the securing elements 23 away from the locking latch 18 in with the securing element 23 corresponding securing element receptacles 24 intervention. In particular, it can be provided that the securing elements 23 together with the bolt 22 can be disengaged from the corresponding receptacles by means of a common handling means. This means that the securing elements can be provided 23 mechanically with the bolt 22 are connected.

The fuse element receptacles 24 can on a push unit carrier 25 be arranged. The closure element 10 or the thrust unit 7 is over at least one hinge 26 , here three hinges 26 , with the push unit carrier 25 pivotally connected. The hinges 26 are on one edge 20 opposite, further edge 27 the thrust unit or the closure element 10 arranged. Consequently, the closure element 10 or the thrust unit 7 in relation to the push unit carrier 25 pivotable between the operating position and the loading position.

In 3 the transport track is particularly good 2 to recognize which is designed in the present example as a roller or roller conveyor. That means that on the transport track 2 erected packages each tangent to several rollers or rolls 28 the roller conveyor or transport conveyor 2 border and are based on it. Alternatively or additionally, the transport track 2 have a flat and particularly smooth surface, so that the packages when moving the closure element 10 or the thrust unit 7 can be slid over this smooth surface.

4 shows a plan view of the thrust unit 7 isolated from the transport channel 12 , Only side elements 14 the limiting device 11 are shown. It can be seen in particular that the thrust unit carrier 25 is formed in several parts, that is to say several, in the present case four support elements 29 has, so that the closure element 10 in relation to the four support elements 29 is pivotable.

Referring again to 1 instructs the loading device 1 , especially their thrust device 6 , one along the transport track 2 arranged guide device 30 along which the thrust unit 7 perpendicular to the transport track 2 is held. In the present example, the guide device points 30 per long edge 15 the transport track 2 two rail elements 31 on which the pusher 6 when moving them along the transport direction 5 lead linear. As in 4 can be seen, the respective support elements 29 four rolling elements each 32 on which are arranged in pairs and mirror images of each other, so that a first pair of rollers 33 the support element 29 on a top 34 of the corresponding rail element 31 supported. One over the corresponding rail element 31 from the pair of roles 33 spaced second pair of rollers 35 is a bottom 36 of the corresponding rail element 31 facing so that moving the corresponding support member 29 across the rail element 31 is prevented. Furthermore, the respective carrier element prevents 29 for yourself that the thrust unit 7 or the closure element 10 across the guide device 30 rotates. For this purpose, at least one of the rolling elements 32 form-fitting with the corresponding rail element 31 interact.

1 further shows that the pusher 6 a drive unit 37 has, by means of which the thrust unit 7 is drivable. Shows for better clarity 5 a schematic view of the drive unit 37 which is a traction device 38 has that with the thrust unit 7 connected is. That means the thrust unit 7 in relation to the traction device 38 is fixed with this, so that a movement of the traction means 38 mandatory movement of the thrust unit 7 conditionally and vice versa. In the present example the traction device is 38 endlessly formed and is by means of two deflection units 39 . 40 in an upper run 41 and a lower strand 42 divided up. The drive unit 37 further comprises a drive element 43 , by means of which a drive torque on the endless traction means 38 can be applied, whereby the thrust unit 7 by means of the drive element 43 over the endlessly trained traction device 38 is drivable. For example, the drive element 43 as a motor, especially an electric motor 44 , be formed, which rotatably via the output shaft with one of the deflection units, in particular with the deflection unit 40 , connected is.

Between the two outer deflection units 39 . 40 can still further deflection units 45 be provided, each of the upper run 41 or the lower run 42 of the endless traction device 38 redirect. In this way, the drive element 43 or the electric motor 44 on an edge 58 of the transport channel 12 (please refer 1 ) can be arranged. Because like in 1 can be seen, the drive unit 37 two traction devices 38 on which by means of the drive element 43 can be driven together. This is the time of the transport track 2 arranged, and acts equally with two deflection units 40 together, each with one of the traction means 38 are in operative connection. This is more precise in 6 shown.

6 shows a perspective exploded view of part of the drive unit 37 , especially how the drive element 43 and the two traction devices 38 interact. As already explained, the drive element can 43 than the electric motor 44 be trained. Alternatively, the drive element 43 the electric motor 44 include. Furthermore, the drive element 43 a gear unit 46 have, the input side and output side are angled by 90 degrees to each other, so that a longitudinal extension of the electric motor 44 parallel to the transport track 2 can be arranged (cf. 1 ). An output shaft 47 of the drive element 43 is non-rotatable with the two deflection units 40 connected, the two deflection units 40 rotationally fixed to each other on a shaft element 48 are arranged. The wave element 48 runs transversely to the longitudinal extent of the transport track 2 along a narrow edge of the same. Referring again to the 1 and the 5 can be seen that the drive element 43 or the electric motor 44 from a middle level 49 of the endless traction device 38 is disengaged. This causes that, even though the wave element 48 the two side deflection units 40 connects to each other, an end opening of the transport channel 12 , especially at the end 3 the transport track 2 , free is. In other words, crosses the wave element 48 the front opening of the transport channel 12 Not.

7 shows a schematic and perspective view of the drive unit 37 with other elements of the same. So the drive unit points 37 for example support rails 50 on the top of which the respective upper run 41 the corresponding traction device 38 is supported so that the upper run 41 along the longitudinal extent of the loading device 1 not sagging. On the respective support rail 50 is at least one tensioning device 51 provided, whereupon a respective lower run 42 of each traction means 38 rests, so that this also along the longitudinal extent of the loading device 1 not sagging. Furthermore, a variety of side guide elements 52 provided which the respective upper run 41 of the corresponding traction device 38 protrude so that the upper run is prevented 41 of the corresponding traction device 38 breaks out laterally.

The respective deflection unit 40 and or 45 can be a tensioner 53 have, by means of which the corresponding traction means 38 along the longitudinal extent or along the transport direction 5 can be tensioned or pre-tensioned so that the traction means 38 is always kept taut in an advantageous manner.

The respective traction device 38 is advantageously designed as a textile belt on which a tooth structure is fixed. To the respective traction device 38 particularly efficient, that is to say under particularly low slip, by means of the drive element 43 to be able to drive, the drive element 43 have a gearwheel or wedge gear on its output side, which matches the tooth structure of the traction means 38 combs. This means that the deflection units are advantageous 40 which are in operative connection with the drive element 43 stand, are formed as such a gear or wedge or have such a gear or wedge.

Furthermore, in 7 to recognize that with the traction means 38 respective towing elements 54 are connected. In particular, the two are with drag elements 54 firmly with the respective upper run 41 the corresponding traction device 38 connected so that the two drag elements 54 equally about the respective traction device 38 along the direction of transport 5 are movable as far as the two traction means 38 by means of the drive element 43 are driven. Between the two drag elements 54 is the closure element 10 or the thrust unit 7 mounted by one of the two drag elements 54 one of the hinges 26 and on the corresponding other drag element 54 the locking latch 18 is arranged. For a particularly simple orientation or assignment of the individual figures to one another, this is with the hinge 26 equipped dragging element as 54a and that with the locking latch 18 equipped dragging element as 54b designated and in 4 entered accordingly.

7 shows the charging device in a schematic side view 1 which is a sensor unit 55 has, which can for example be designed as a light barrier unit. A corresponding light barrier path runs at the end in the present example 3 the charger 1 across the opening of the transport channel 12 and covers the opening at least for the most part, in particular completely. Comes in by means of the thrust unit 7 driven package along the transport track 2 at the end 3 the charger 1 on, the package breaks through the light barrier section at least partially, as a result of which the light barrier or the sensor unit 55 one wireless and / or wired to the sensor unit 55 connected control unit 56 provides a corresponding sensor signal. The control unit 56 can be designed to drive the 37 to control. Accordingly, it can be provided that as soon as a package reaches the end 3 reached the loading device and there interrupts the light barrier path, a further movement of the thrust unit 7 along the direction of transport 5 by means of the control unit 56 interrupted and / or moving the thrust unit 7 is not started. In this way it is particularly advantageously ensured that a package does not accidentally end over the end 3 the charger 1 is pushed out and therefore not from the loading device 1 fall out. It is understood that the sensor unit 55 can be designed according to other sensor principles. That means the sensor unit 55 can be an optical, acoustic and / or capacitive sensor or can at least include such a sensor. It can further be provided that, based on the sensor signal, the deliverer is provided with information optically, haptically, acoustically etc. that the package is at the end 3 the charger 1 has consequently arrived at a removal position.

Furthermore, a further sensor unit 57 be provided, which is wireless and / or wired with a further control unit and / or with the control unit 56 connected is. This other sensor unit 57 is at the end 4 the charger 1 arranged and designed to recognize whether the thrust unit 7 is moved to an end position. This means that it is effectively prevented from moving the pusher unit 7 against the direction of transport 5 the drive unit 37 further the appropriate traction devices 38 drives, although the thrust unit 7 at the end 4 the charger 1 has arrived. Because the one with the second sensor unit 57 related control unit 56 controls - as already described - the drive element 43 depending on the corresponding sensor signals from the sensor unit in the 55 . 57 , The sensor unit 57 can be designed according to an optical, capacitive, acoustic, etc. sensor principle. Furthermore, the sensor unit 55 and / or the sensor unit 57 have a mechanically actuated switch, which in each case when the corresponding end positions of the thrust unit are reached 7 or the package is actuated by this and switched as a result.

9 shows a perspective view of a cargo space arrangement 59 with a variety of loaders 1 , It is in 9 particularly easy to see that an upper element 13 the limiting device 11 which along the transport track 2 is arranged and together with this the respective transport channel 12 forms, through a transport track 2 a further loading device arranged above 1 can be formed. A top loading device 1 which goes directly to a roof of the hold 9 is free of charge directly with this charging device 1 connected upper element 13 be, with falling out of packages from the corresponding loading device 1 is still prevented in the top loading device 1 through the roof of the cargo area 9 is limited. Similarly, the respective openings of the transport channels 12 be delimited by a door of the loading space, so that in the respective loading device 1 loaded packages, in particular form-fitting, between the respective push units 7 and the hold door are held. In this way, a form-fitting load securing of the packages which is in the respective loading device is particularly easy 1 are invited.

10 shows a perspective view of the parcel transport vehicle 8th in a loading station or in a transfer station. It can be seen particularly well that the end 3 the corresponding loading device 1 on a rear side of the hold 9 is arranged. For particularly easy loading of the loading device 1 it can be provided that the entire loading device 1 is adjusted into a loading position, the loading device 1 at least partially from the hold 9 protrudes. It can further be provided that for loading the loading device 1 these completely out of the hold 9 Will get removed. In the present example, the loading device is used for loading 1 equipped with a so-called one-shot loading system. Here, the corresponding in the loading device 1 packages to be loaded 58 pre-picked in the loading station, at which point it is not necessary for the delivery vehicle or parcel transport vehicle 8th is on site at the loading station. The pre-picked packages 58 are like in 10 to recognize, lined up in a row, and are then, for example by means of a slide, in the transport channel 12 the corresponding loading device 1 introduced. In this way the loading device 1 and as a result the parcel transport vehicle 8th Can be loaded particularly quickly, so that the parcel transport vehicle has a lifespan 8th can be kept particularly low, so that the package transport vehicle 8th can be operated particularly efficiently.

Overall, the invention shows how today's challenge of more and more online orders and more and more deliveries can be met. Because the increasing volume of deliveries of packages or shipments leads to more and more vehicles, especially on the streets. In this case, however, the respective cargo holds of the vehicles are not completely usable in space since corridors or access areas must be kept clear in today's cargo holds in order to obtain selective access to the goods transported in the cargo hold. As a result, the respective emissions are particularly high, based on the respective shipment. By means of the loading device according to the invention 1 it is possible to dispense with such access areas in the interior of the loading space, so that the loading spaces of the parcel transport vehicles are used particularly efficiently in terms of space. In other words, due to the charging device 1 more packages in the hold 9 be invited. In particular in connection with loading space optimization software and the use of optimized loading systems in the supply chain, the respective efficiency of the processes of delivering shipments or packages can be increased.
