Descriptive Report of the Invention Patent for INSTALLATION OF PARKING FOR MOTOR VEHICLES.

The present invention relates to a parking system for motor vehicles with a pallet changer device, in which two guides are arranged one above the other for pallets, on which these can be moved horizontally, with a lifting device, which you can raise a pallet from the lower guide to the upper guide and vice versa lower it from the upper guide to the lower guide.

Such a parking facility is known from DE 20 2007 002 069 U1. In this parking facility, vehicles are pushed on pallets by means of a rack conveyor into separate parking compartments of a rack, in which case two guides are placed in each parking compartment and on the rack conveyor which are one above the other. , in which pallets are horizontally guided in a displaceable way above each other. When transferring a pallet from the rack conveyor to a parking position or vice versa, then the upper pallet, on which a motor vehicle is always located, always moves on the aligned upper guides, at the same time an empty pallet is pushed on the lower guides also aligned in the opposite direction, so that in each parking position and on the rack conveyor there is always a pallet, whether it is a pallet occupied by a motor vehicle, that is, an empty pallet.

At the entrance and exit of this known parking facility, a pallet changer device is arranged each time, to which the rack conveyor can be directly connected. At the entrance, a pallet occupied by a motor vehicle pushes on the rack conveyor, and an empty pallet is inserted by the rack conveyor into the pallet changer, namely its lower guide. In the pallet changer, a lifting device then moves the empty lower platform, from the lower guide to the upper guide, once an empty pallet is again available on the upper guide, onto which a motor vehicle can enter.

At the exit, the process is carried out in the opposite way, in this case, in the pallet changer device, the empty pallet is lowered after the vehicle leaves the upper guide by means of the lifting device for the lower guide.

In the case of the known parking facility, a rack conveyor is connected directly to the pallet changer device, which is allocated in stationary terms each time it enters or exits. However, for architectural reasons this is not always possible, for example, when the entire parking facility is arranged underground and when the entrance and exit must be positioned super-terrestrially.

It is the task of the invention to perfect a parking facility according to gender in such a way that even in the case of complex installations the transfer of motor vehicles between an entrance or exit on the one hand, and the rest of the parking facility on the other hand, can be carried out simply and especially quickly.

In the case of a parking installation of the type initially described, this task is solved according to the invention by the fact that the pallet changer device can be moved by means of a motor drive between an entry or exit position on the one hand , in which a pallet is aligned on the upper guide each time with the entrance or exit of the parking facility, and between a pallet transfer station on the other hand, in which both guides of the pallet changer device are aligned with guides arranged one above that of a rack conveyor or a parking rack, and that a control is provided, which coordinates the movement of the pallet changer device between the entry or exit position and the pallet transfer station and the activation of the lifting device in such a way that the lifting movement of the pallets in the pallet changer device takes place during the movement of the changer device between the entry or exit position and the pallet transfer station.

In contrast to the stationary pallet changer device, then the pallet changer device is mobilely equipped, and in this way it can be moved or moved from the incoming or outgoing position to a pallet transfer station. In the entry or exit position, each pallet is aligned on an upper guide of the pallet changer device with the entry or exit, respectively, so that a vehicle can climb onto this upper pallet or, respectively, from this. The pallet changer device then moves to a second position, namely a pallet transfer station, in which the guides of the pallet changer device are aligned with guides on a rack conveyor or with guides in the parking positions of a rack, so pallets can be exchanged between the pallet changer device and this rack carrier or the parking rack. During this movement of the pallet changer device between the entry and exit position on the one hand, and the pallet transfer station on the other hand, then the pallet changer is moved from the lower to the upper guide, respectively , from the upper guide to the lower guide, so no additional time is required for this movement. The simultaneous activation of the drives for the movement of the pallet changer device itself and for the activation of the lifting device on the other hand ensures that the pallet changer device when reaching the entrance, respectively, when reaching the pallet transfer station , make the pallet available on the guide, which they need at the entrance, exit or at the pallet transfer station each time for the transfer of the pallets and for the transit and unloading of the pallets. An additional expenditure of time for changing the pallets in the pallet changer device is avoided by the fact that this exchange takes place during the movement of the pallet changer device. In this case, it is advantageous if the lifting or lowering of the pallet in the pallet changer device can be completed completely during the displacement of the pallet changer device. However, in principle it would also be possible to carry out only a part of the lifting or lowering movement of the pallets on the pallet changer device during the movement of the pallet changer device between the entry and exit position and the pallet transfer station, and execute partially this exchange of the pallet between the guides located one above the other also during the stop of the pallet changer device. Above all, it is essential that the time taken to move the pallet changer device between the pallet transfer station and the entry or exit position for changing the pallets between both guides is used.

It is advantageous if the control coordinates the movement of the pallet changer between the entry or exit position and the pallet transfer station and the activation of the lifting device in such a way that the pallets of the pallet changer device during the movement of the pallet. pallet changer device from the pallet transfer station to the input position are raised from the lower to the upper guide, respectively, be lowered during the movement of the pallet changer device from the output position to the pallet transfer station to the guide bottom. In the case of a configuration of this type, empty pallets are always exchanged on the pallet changer device between the upper and lower guides.

In principle, the pallet changer device could be horizontally displaceable or could also be moved in another way between the entry or exit position on the one hand and the pallet transfer position on the other hand, it is especially advantageous if in this case the pallet changer device pallets can be moved perpendicularly up or down, therefore, in other words, if the pallet changer device is placed on an elevator.

The following description of preferred embodiments of the invention serves together with the drawing for further explanation. Show:

The invention will be explained further by the example of a parking installation 1, which is arranged under an access plane 2, in an internal space 3 of a building 4. In the access plane 2, an entrance 5 is arranged, and in another place an exit 6, in this region there is an opening 7 in the region of the access plane 2, which is preferably covered by a specific building 8, this building 8, can be an entrance station or a station exit and can have a side door opening 9, through which a motor vehicle 28 can enter building 8, or can exit building 8.

In the internal space 3, a large number of stationary parking positions 10 are arranged one above the other, between these parking spaces an intermediate space 11 is left free, in which a rack conveyor 12 is movable.

Each parking position 10 has two horizontal guides 13, 14 which are above each other, on which pallets 15 can be inserted, on which the vehicles can be received.

The same goes for the rack conveyor 12, it can be moved in the intermediate space both in a perpendicular direction and also in a horizontal direction in such a way that this, with its two horizontal guides 13, 14 that are one above the other, is each Once aligned with corresponding guides 13, 14 from a parking position, it is therefore possible to change a pallet 15, both on the upper and lower guides.

In the drawing, the stationary parking positions are represented only through the upper and lower guides 13 and 14, respectively, represented schematically, the rack conveyor 12 only through its upper guide 13 and its lower guide 14. These guides 13, 14, of the rack conveyor 12, in fact are arranged on an elevator, which in this way makes it possible to raise and lower the guides 13, 14, of the rack conveyor 12, in addition, the lift can also be moved in a horizontal direction in the intermediate space 11, so that it can also reach parking positions 10, arranged in front of the drawing plane of figure 1 and behind the drawing plane of figure 1.

The parking positions 10 essentially occupy the entire space on both sides of the intermediate space 11, however, in the region below an entrance 5, and below an exit 6, a space is left free, in which it is not arranged no stationary parking position 10. Instead, a pallet changer device 16, which is part of an elevator, is arranged in this space, through which the pallet changer device 16 can be lowered from an upper position in which this in essence is aligned with the access plane 2, for a pallet transfer station 29, in which it is aligned with the guides 13, 14 of the rack conveyor 12, if this rack conveyor 12, in turn is found in a higher position.

The lifting movement of the pallet changer device 16 takes place by means of a motor drive 17, which is connected via a control circuit 18 with a control 19, and is activated through it. In figure 1, the drive 17, is only schematically outlined as part of the pallet changer device 16, in fact the drive can also be evidently arranged externally in buildings 4 or 8, and not in the elevator itself, which supports the pallet changer device 16.

In the pallet changer device 16, two guides 20, 21 are arranged one above the other, namely, these guides are configured by means of a pair of lower parallel running tracks 22, and a pair of upper running tracks 23 arranged above these. The lower bearing rails 22 are stationarily arranged on the pallet changer device 16, while the upper bearing rails 23 are retained on a support 24, which is swiveled outward each time around a lower swing, as soon as the upper running rails 23, can be turned laterally outward, as shown in figure 3. In addition, in the pallet changer device 16, a lifting device 25 is arranged, which grips the lower side of a pallet 15, which is movably supported on one of the rolling rails 22 or 23. This lifting device 25 can raise and lower pallet 15, for example, in this case it can be a hydraulic lifting device that handle with several pressure cylinders at different points on a pallet 15, in order to raise and lower it evenly and parallel to itself.

In this way, it is possible to lift the pallets of the lower roller rail 22 upwards, when the supports 24 are rotated outwards with the upper roller tracks 23, since this way the space above the lower roller tracks 22 is freed up. In this way, the pallet 15 can be raised so much that the supports 24, with the upper bearing rails 23, can again be rotated inwards under the pallet, so that when the pallet is next lowered, it is received on the upper running rails 23, and there it is displaceable. In this way it is possible to change the position of the pallet 15, between the upper running rails 23, and the lower running rails 22. In figure 2, a pallet is shown on the upper running rails 23, in this case the supports 24, are rotated inward. In figure 3, the supports 24 are rotated outwards, and the pallet 15 is lowered by means of the lifting device 25, for the lower roller tracks 22. Of course, this procedure can be reversed.

This exchange of pallets 15, between the bearing rails 22, 23 arranged one above the other, can take place by means of a motor drive 26, which activates the supports 24 on the one hand, and the locking device on the other hand. elevation 25, this drive 26 is only shown schematically in figure 1. This drive is also connected via a control circuit 27, with control 19, so this control controls both the lifting movement of the pallet changer device 16 in their entirety, as well as the exchange of pallets 15, between both roller tracks 22 and 23.

When operating this parking facility 1, motor vehicles 28 are parked on parking pallets 15, and these parking pallets are then transferred via pallet changer 16 and rack conveyor 12 to individual parking positions 10 and, respectively, in an inverted sense, they search again for parking positions. Alignment is always carried out between the pallet changer device 16 and the rack conveyor 12, or between the rack conveyor 12 and a parking position 10, in such a way that the upper guides are always aligned with the upper guides. and the lower guides each time with the lower guides. When aligning, pallets always move simultaneously on both the upper and lower guides, and precisely in the reverse direction, so that in each parking position 10, they always remain on the rack conveyor 12 and on the pallet changer device 16, each once a pallet 15. In this case, pallets occupied with a motor vehicle are always on the upper guides.

In order for this pallet exchange system to function continuously, pallets 15 must be exchanged in the pallet changer device 16, each time between both guides 20, 21.

This is described through the example of figures 4 to 6, for a pallet changer device 16, which is allocated to an outlet 6.

In figure 4, the pallet changer device 16 is shown, in an elevated position, the pallet 15, is located on the upper guide 21, and thus is aligned with the access plane 2, as soon as a motor vehicle 28, disposed on pallet 15, can leave the exit.

When a motor vehicle parked in a parking position must be transported to the exit, then control 19 is activated correspondingly by the user, and the user now takes the pallet changer device 16, from the upper position shown in figure 4, down to the position lowered, in which the pallet changer device 16 is located in a pallet transfer station 29 (figure 6). During the lowering movement of the pallet changer device 16, activation 26 of the lifting device 25 and the support 24 is simultaneously activated via control 19, as soon as the pallet is lowered from the upper guide 21 to the lower guide 20. This is shown in figure 5, in the intermediate region between the upper and lower position of the pallet changer device. As soon as the pallet changer device 16 is in the lower position, therefore, at the pallet transfer station 29, the pallet has arrived at the lower guide 20, so after aligning the pallet changer device 16 with the rack conveyor 12, a pallet 15 occupied by a motor vehicle 28, can enter the upper guide 14 of the rack conveyor 12, the upper guide 21 of the pallet changer device 16, as shown in figure 6. Simultaneously the free pallet of the lower guide 20, moves from the lower guide 20 of the pallet changer device 16 to the lower guide 13 of the rack conveyor 12, and then the pallet changer device 16 moves again to the elevated position of figure 4, in which the vehicle parked on the pallet can exit the exit.

For the exchange of pallets between both guides 20, 21, of the pallet changer device 16, no additional time is required, since this exchange takes place during the lowering movement of the pallet changer device 16, to the lower position .

In figures 7 to 9, the situation is shown next to an entrance 5. When there the pallet changer device 16 is in the lowered position, therefore, in the pallet transfer station 29, a motor vehicle arranged on a pallet 15 on the upper guide 21, it can be moved with the pallet 15, to the upper guide 14 of the rack conveyor 12, simultaneously a free pallet moves from the lower guide 13 of the rack conveyor 12, to the lower guide 20 of the pallet changer device 16.

Then the pallet changer device 16 rises via control 19, simultaneously changing the free pallet of the lower guide 20 to the upper guide 21. When the pallet changer device 16 reaches the upper position, then also the free pallet has been transferred to the upper guide 21 of the pallet changer device 16, and is now aligned with the access plane 2, as soon as a motor vehicle 28 can rise on the pallet (figure 9).

After lowering the pallet changer device 16 to the pallet transfer station 29, the pallet occupied by the vehicle can be moved, as shown in figure 7, of the upper guide 21 of the pallet changer device 16, to the upper guide 14 of the rack conveyor 12, as soon as the rack conveyor 12 then transports the pallet occupied with the motor vehicle in a known manner to a parking position and transfers it to it.

Here, too, the free pallet is moved from the lower guide 20 to the upper guide 21 of the pallet changer device 16 during the lifting movement of the pallet changer device 16 and therefore does not require any additional time.

In order that the exchange of pallets between both guides 20 and 21, of the pallet changer device 16, can take place during the lifting movement of the pallet changer device 16, evidently 10 steps must be taken to ensure that for supports 24, which rotate outwards during this exchange, there is sufficient space, in the case of the figures in figures 2 and 3, this is outlined by walls 30, recessed laterally in relation to the pallet changer device 16. In practice, of course it may be necessary to take appropriate precautionary measures in terms of construction, so that the supports 24, when pivoting outward and when the simultaneous lifting movement of the pallet changer device 16, cannot collide with other construction parts.
