Description

The invention relates to a park for motor vehicles with a pallet changing device in which two guides for pallets are arranged one above the other, in which they are horizontally displaceable, with a lifting device lifting a pallet from the lower guide in the upper guide and vice versa from the upper guide can lower into the lower guide, wherein the pallet changing device by means of a motor drive between an entry or exit position on the one hand, in which a pallet in the upper guide is respectively aligned with the entrance or exit of the park, and between a pallet transfer station on the other hand is movable in which both guides of the pallet changing device are aligned with superimposed guides of a rack conveyor or a parking rack, and with a controller for coordinating the movement of the pallet changing device between the entry or exit position and the pallet hoist Rührestation and the activation of the lifting device.

A park of this kind is known from the DE 20 2007 002 069 U1 , In this park motor vehicles are pushed onto pallets by means of a rack conveyor in individual storage compartments of a shelf, while two superimposed guides are arranged in each storage compartment and in the rack conveyor, in which pallets are guided one above the other horizontally displaceable. When transferring a pallet from the rack conveyor to a parking space or vice versa always the top pallet on which a motor vehicle is, each shifted in the aligned upper guides, at the same time an empty pallet is pushed in the likewise aligned lower guides in the opposite direction, so that each pallet and the rack conveyor always a pallet is always present, either occupied with a motor vehicle pallet or an empty pallet.

At the entrance and at the exit of this known park a pallet changing device is arranged, to which the rack conveyor is directly connected. At the entrance a occupied with a motor vehicle pallet is pushed onto the rack conveyor and an empty pallet is inserted from the rack conveyor in the pallet changer, in its lower guide. In the pallet changer now a lifting device moves the empty, lower platform of the lower guide in the upper guide, so that after this shift in the upper guide again an empty pallet is available to which a motor vehicle can retract.

In the exit, the process is reversed, there is lowered in the pallet changing the empty after leaving the motor vehicle pallet of the upper guide by the lifting device in the lower guide.

In the known park, a rack conveyor connects directly to the pallet changing device, which is stationarily associated with each of the entrance or exit. However, this is not always possible for structural reasons, for example, when the entire park is arranged underground and when the entrance and the exit should be positioned above ground.

A similar park is known from the FR 1 331 341 A ,

It is an object of the invention to develop a generic park so that even with complicated systems, the transfer of motor vehicles between a driveway or exit on the one hand and the rest of the park on the other hand can be done easily and especially quickly.

This object is achieved according to the invention in a park of the type described above, that the control of the movement of the Pallet changing device and the lifting movement of the pallets coordinated so that the lifting movement of the pallets takes place in the pallet changing device during movement of the pallet changing device between the entry or exit position and the pallet transfer station.

In contrast to the stationary pallet changing device so the pallet changing device is movably equipped and can thereby be moved or moved from the entry position or from the exit position in a pallet transfer station. In the entry position or in the exit position, a pallet in each case is aligned in an upper guide of the pallet changing device with the entrance or the exit, so that a motor vehicle can drive onto this upper pallet or move away from it. The pallet changing device then moves to a second position, namely a pallet transfer station, in which the guides of the pallet changing device are aligned with guides of a rack conveyor or with guides on the shelves of a shelf, so that pallets can be exchanged between the pallet changing device and this rack conveyor or the parking rack. During this movement of the pallet changing device between the entry or exit position on the one hand and the pallet transfer station on the other hand, the pallet changing device now moves the pallet from the lower to the upper guide or from the upper guide to the lower guide so that there is no additional movement for this displacement Time is needed. The simultaneous activation of the drives for the movement of the pallet changer itself and for the activation of the lifting device on the other hand ensures that the pallet changing device when reaching the entrance or when reaching the pallet transfer station provides the pallet in the leadership in which they at the entrance to the Exit or at the pallet transfer station in each case for the transfer of the pallets and for driving on and unloading the pallets are needed. One additional time required for the change of the pallets in the pallet changing device is thereby avoided, since this change takes place during the movement of the pallet changing device. It is advantageous if the raising or lowering of the pallet can be completely completed in the pallet changing device during the displacement of the pallet changing device. In principle, however, it would also be possible to carry out only a part of the lowering or lifting movement of the pallets in the pallet changing device during the movement of the pallet changing device between entry and exit position and pallet transfer station and this change of pallet between the superimposed guides partially during standstill of the pallet changing device perform. It is essential, above all, that the time of displacement of the pallet changing device between pallet transfer station and entry or exit position for the change of pallets between the two guides is used.

It is advantageous if the controller coordinates the movement of the pallet changing device between the entry or exit position and the pallet transfer station and the activation of the lifting device such that the pallets of the pallet changing device during the movement of the pallet transfer device from the pallet transfer station to the entry position from the lower to the upper guide be raised or lowered during the movement of the pallet changing device from the exit position to the pallet transfer station in the lower guide. In such a configuration always empty pallets are exchanged in the pallet changing device between the upper and the lower guide.

Basically, the pallet changing device between the entry or exit position on the one hand and the pallet transfer position on the other be moved horizontally or in any other way be movable, it is particularly advantageous if the pallet changing device in the vertical direction is movable up or down, so if in other words, the pallet changing device is placed on a lift.

The invention is discussed below using the example of a parking facility 1, which is arranged below a driveway level 2 in an interior 3 of a building 4. In the access level 2 is a driveway 5 and at another point an exit 6, in this area a leading into the interior 3 opening 7 is provided in the area of the access level 2, which is preferably covered by its own building 8, this building. 8 may be a driveway or exit station and have a side door opening 9 through which a motor vehicle 28 in the building 8 on or out of the building 8 can extend.

In the interior 3, a plurality of stationary parking spaces 10 are arranged like a shelf above each other, between these parking spaces, a gap 11 is released, in which a rack conveyor 12 is movable.

Each parking space 10 has two superimposed, horizontal guides 13, 14, can be inserted into the pallets 15 on which motor vehicles can be accommodated.

The same applies to the rack conveyor 12, this can be moved in the space both in a vertical and in a horizontal direction so that it is aligned with its two superimposed guides 13, 14 with corresponding guides 13, 14 of a parking space, so that both in the upper guides as well as in the lower guides the replacement of a pallet 15 is possible.

In the drawing, the stationary parking spaces are represented solely by the schematically illustrated upper and lower guides 13 and 14, the rack conveyor 12 solely by its upper guide 13 and its lower guide 14. These guides 13, 14 of the rack conveyor 12 are actually on an elevator arranged, which thus allows lifting and lowering of the guides 13, 14 of the rack conveyor 12, also the elevator can also be moved in the horizontal direction in the intermediate space 11, so that it is also in front of the plane of the FIG. 1 and behind the drawing plane the FIG. 1 arranged parking spaces 10 can reach.

The parking spaces 10 occupy substantially the entire space on both sides of the space 11, but in the area below a driveway 5 and below an exit 6 a space is kept free, in which no stationary parking space 10 is arranged. Instead, a pallet changing device 16 is arranged in this space, which is part of an elevator, by means of which the pallet changing device 16 can be lowered from an upper position, in which it is substantially aligned with the access level 2, into a pallet transfer station 29, in which it substantially with the guides 13, 14 of the rack conveyor 12 is aligned when this rack conveyor 12 is in turn in an upper position.

The lifting movement of the pallet changing device 16 is effected by a motor drive 17, which is connected via a control line 18 to a controller 19 and is activated by this. The drive 17 is in FIG. 1 only schematically indicated as part of the pallet changing device 16, of course, of course, the drive can also be arranged externally to the buildings 4 or 8 and not on the elevator itself, which carries the pallet changing device 16.

In the pallet changing device 16, two guides 20, 21 are arranged one above the other for a parking pallet 15, namely, these guides are formed by a pair of parallel lower rails 22 and a pair of upper rails arranged above 23. The lower rails 22 are on the pallet changer 16th Stationarily arranged, while the upper rails 23 are held on a carrier 24 which is pivotally mounted in each case about a lower pivot point to the outside, so that the upper rails 23 can be swung laterally, as shown in FIG FIG. 3 is shown. Furthermore, in the pallet changing device 16, a lifting device 25 is arranged, which acts on the underside of a pallet 15 which is mounted in one of the rails 22 or 23 movable. This lifting device 25 can raise and lower the pallet 15, for example, it may be a hydraulic lifting device which engages with several printing cylinders at different locations of a pallet 15 to raise and lower these evenly and parallel to itself. It is thereby possible to lift the pallets from the lower running rail 22 upwards when the carriers 24 are laterally swung out with the upper running rails 23, since in this way the space above the lower rails 22 is released. The pallet 15 can be raised so far that the carrier 24 can be pivoted with the upper rails 23 below the pallet again, so that in a subsequent lowering of the pallet it is received in the upper rails 23 and stored there displaceable. In this way, it is possible to change the position of the pallet 15 between the upper rails 23 and the lower rails 22. In FIG. 2 a pallet is shown in the upper rails 23, while the carrier 24 are pivoted. In FIG. 3 the carriers 24 are swung out, and the pallet 15 is lowered by the lifting device 25 in the lower rails 22. Of course, this process is reversible.

This exchange of the pallets 15 between the superimposed rails 22, 23 can be done by means of a motor drive 26, on the one hand, the carrier 24 and on the other hand, the lifting device 25 is activated, this drive 26 is in FIG. 1 shown only schematically. He is also connected via a control line 27 to the controller 19, so that this control controls both the lifting movement of the pallet changing device 16 as a whole and the change of the pallets 15 between the two rails 22 and 23.

In the operation of this park 1 motor vehicles 28 parked on parking pallets 15, and these parking pallets are then passed over the pallet changing device 16 and the rack conveyor 12 to the individual parking spaces 10 and picked up in the reverse direction of the parking spaces again. In all cases, an alignment between the pallet changing device 16 and the rack conveyor 12 or between the rack conveyor 12 and a parking space 10 in such a way that the upper guides are aligned respectively with the upper guides and the lower guides respectively with the lower guides. In one orientation, pallets are always moved simultaneously in both the upper and in the lower guide, in the opposite direction, so that in each parking space 10, in the rack conveyor 12 and in the pallet changing device 16 always a pallet 15 remains. With a motor vehicle occupied pallets are always in the upper guides.

In order for this system of pallet change works continuously, the pallets 15 must be changed in the pallet changing device 16 between the two guides 20, 21.

This is exemplified by the FIGS. 4 to 6 for a pallet changing device 16 which is associated with an exit 6.

In FIG. 4 the pallet changing device 16 is shown in its raised position, the pallet 15 is located in the upper guide 21 and is thus aligned with the access level 2, so that an arranged on the pallet 15 motor vehicle 28 can leave the exit.

If a parked on a parking space motor vehicle is to be transported to the exit, the controller 19 is activated by the user accordingly, and this now drives the pallet changer 16 from the in FIG. 4 shown upper position down to the lowered position in which the pallet changing device 16 in a pallet transfer station 29 ( FIG. 6 ). During the lowering movement of the pallet changing device 16, the drive 26 of the lifting device 25 and of the carrier 24 is simultaneously activated by the control 19, so that the pallet is lowered from the upper guide 21 into the lower guide 20. This is in FIG. 5 in the intermediate area between the upper position and the lower position of the pallet changing device shown. Once the pallet changing device 16 is in the lower position, ie in the pallet transfer station 29, the pallet 15 has arrived in the lower guide 20, so that after aligning the pallet changing device 16 with the rack conveyor 12 occupied with a motor vehicle 28 range 15 from the upper guide 14 of the rack conveyor 12 in the upper guide 21 of the pallet changing device 16 can retract, as in FIG. 6 is shown. At the same time the free pallet from the lower guide 20 of the pallet changing device 16 is moved into the lower guide 13 of the rack conveyor 12, and then the pallet changing device 16 is again in the raised position of FIG. 4 procedure in which the parked on the pallet motor vehicle can exit from the exit.

For the change of the pallets between the two guides 20, 21 of the pallet changing device 16 no additional time is required because this change takes place during the lowering movement of the pallet changing device 16 in the lower position.

In the FIGS. 7 to 9 the situation at a driveway 5 is shown. If there is the pallet changing device 16 in the lowered position, ie in the pallet transfer station 29, a arranged on a pallet 15 in the upper guide 21 motor vehicle can be moved with the pallet 15 in the upper guide 14 of the rack conveyor 12, at the same time is a moved free pallet from the lower guide 13 of the rack conveyor 12 in the lower guide 20 of the pallet changing device 16.

Subsequently, the pallet changing device 16 is raised by the controller 19, at the same time, the change of the free pallet from the lower guide 20 in the upper guide 21. If the pallet changing device 16 reached the upper position, the free pallet has been transferred to the upper guide 21 of the pallet changing device 16 and is now aligned with the access level 2, so that a motor vehicle 28 can drive onto the pallet ( FIG. 9 ).

After lowering the pallet changing device 16 in the pallet transfer station 29 can in the off FIG. 7 apparent manner occupied by the motor vehicle pallet from the upper guide 21 of the pallet changing device 16 are moved into the upper guide 14 of the rack conveyor 12, so that the rack conveyor 12 then transported in a conventional manner, the occupied with the motor vehicle pallet to a parking space and at hands over this.

Again, the displacement of the free pallet from the lower guide 20 in the upper guide 21 of the pallet changing device 16 during the lifting movement of the pallet changing device 16 and therefore requires no additional time.

Thus, the change of the pallets between the two guides 20 and 21 of the pallet changing device 16 can be done during the lifting movement of the pallet changing device 16, of course, care must be taken to ensure that there is enough space for the swung out during this change carrier 24, this is in the illustrations of the Figures 2 and 3 indicated by laterally opposite the pallet changer 16 recessed walls 30. In practice, it may well be necessary to take appropriate structural precautions so that the carrier 24 does not collide with other components during pivoting and the simultaneous lifting movement of the pallet changing device 16.
