Definitions

  • the invention relates to a parking system with parking pallets which can be moved on a roadway and are arranged next to one another and each have their own drive.
  • Parking systems of this type normally comprise a large number of parking pallets, which are arranged next to one another and can be moved individually or together on a carriageway, for example on rails. This makes it possible to move parking pallets with motor vehicles parked thereon, if necessary, thereby creating gaps for driving into a parking area behind them or aligning the parking pallets with an entrance. Overall, by using such parking pallets, the space available for parking motor vehicles can be used much more effectively, since otherwise necessary travel routes can be occupied with such movable pallets.
  • each parking pallet carries a signal-generating sensor on its two sides facing the carriageway in the event of obstacles in the guideway, and in that this signal is a control reversing the direction of travel of this parking pallet operated.
  • the drive of the parking pallet that strikes the unforeseen obstacle is therefore not simply switched off, but on the contrary, the direction of travel of this parking pallet is reversed.
  • This reversal of direction takes place only on the parking pallet which has hit the unforeseen obstacle and regardless of the operating state of a central control system which controls the entire system.
  • control activates a change of direction for an electromotive drive, which comprises two relays that are mechanically interlocked.
  • These relays are constructed in such a way that a switchover of a relay is only possible if the respective other relay is in an interruption position in which no supply voltage is supplied to the motor supplied via this relay. This ensures that the motor is not supplied with differently polarized drive voltages at the same time, but that in any case the supply voltage corresponding to the reverse direction of rotation is only applied when the drive motor is at least briefly disconnected from the original supply voltage.
  • each platform is assigned a control device which measures the power of the drive motor and which switches off the drive motor when a certain power consumption is exceeded. This ensures in particular that the drives on the the intended obstacle-hitting platform and the following platform are switched off when the two platforms abut against one another as a result of the reversal of the direction of the foremost platform. This collision of the platforms driven in different directions leads to an increased power consumption of the drive motors, and this effect switches off the motors of these two pallets. If further pallets run onto the two disused pallets, their motors are also switched off due to the sudden braking and the increased power consumption. This shutdown occurs regardless of whether a central controller has received a signal about the unforeseen emergency stop.
  • a transmission device which feeds the signal from the sensor to a central control and if the central control generates a signal which switches off the drives of all pallets.
  • the signal that switches off the drives of all pallets is preferably delayed in time compared to the signal that reverses the direction of the drive of the parking pallet with the actuated sensor.
  • Figure 1 a plan view of a parking system with three parking pallets movable on rails;
  • Figure 2 is an enlarged partial view of area A in Figure 1; i
  • Figure 3 a circuit diagram of the load circuit for the drive motor of a pallet
  • Figure 4 a circuit diagram for the control of the direction change.
  • the parking system or the parking system shown only partially in FIGS. 1 to 3 comprises a travel path with two rails 1 and 2 laid parallel to one another and electrically insulated from one another, on which a plurality of parking pallets 3 are movably mounted.
  • Each parking pallet 3 has its own drive motor 4, which can move the respective parking pallet 3 along the rails 1 and 2.
  • the drive motors 4 are controlled by a central controller 5, which is arranged in a stationary manner and is connected via lines 6, 7 to each of the two rails 1 and 2, respectively. These lines 6 and 7 not only transmit the supply voltages which operate the drive motors themselves, but also control signals which activate and brake the drive motors in one direction or the other as required.
  • Each parking pallet in turn carries a pallet control 8 for recognizing and processing the control signals brought in via the rails 1 and 2, and this control tion 8 supplies the respective drive motor 4 with a supply voltage when the central control 8 requests activation of this drive motor 4.
  • Each parking pallet 3 carries a sensor on its two opposite longitudinal sides 9 and 10, respectively, which detects obstacles arranged in the path.
  • a sensor can be a swivel bar 11 which extends over the entire length of a parking pallet and is swiveled when it encounters an obstacle and thereby actuates a switch.
  • Other sensors are also conceivable, for example light barriers, pneumatic safety edges or non-contact switches, for example inductive switches.
  • each parking pallet carries buffers 12 with which adjacent parking pallets are supported against one another without actuating the swivel bars 11 acting as sensors (FIG. 2).
  • adjacent parking pallets can therefore be moved next to one another without actuating the swivel bars 11; these swivel bars 11 are only actuated on the foremost pallet if an unforeseen obstacle occurs on the route.
  • the circuit shown in FIG. 3 initially comprises a rectifier 13 for rectifying the AC supply voltage supplied via the rails.
  • This DC voltage can be applied to the drive motor 4 via a motor contactor 14 or a motor contactor 15 with either the opposite polarity, so that the motor rotates in one direction when the motor contactor 14 is actuated, and in the opposite direction when the motor contactor 15 is actuated .
  • Both motor contactors 14 and 15 also each connect a signal line 16 or 17 to a signal voltage line 18 which, for example, has a DC signal voltage of 12 volts poses.
  • the signal lines 16 or 17 each carry this signal voltage when the motor is operating either in the counterclockwise or clockwise direction, that is to say the presence of a voltage on one of the two signal lines is a sign of the operation of the motor in one or the other Direction.
  • a brake line 19 connecting the two ends of the motor is provided, which short-circuits the two ends of the motor when the two motor hatches 14 and 15 are open, that is to say when no supply voltage is supplied to the motor. This causes the motor to brake.
  • the motor contactors 14 and 15 are actuated by the circuit shown in FIG. 4, which operates as a function of the signals which are brought in by the central control 5 via the rails.
  • a line 20 is provided for actuating the motor contactor 14 and can be applied to a supply line 22 via a coupling relay 21.
  • the coupling relay 21 When the coupling relay 21 is actuated, the supply voltage of the supply line 22 is applied to the motor contactor 14, which thereby supplies the motor with the supply voltage for one direction of rotation.
  • a power 23 is provided for the motor contactor 15, which can also be connected to the supply line 22 via a coupling relay 24.
  • the signals for actuating the coupling relays 21 and 24 are made available by the central control 5 and are brought about via the rails 1 and 2.
  • a switch 25 or 26 is inserted into both the line 20 and the line 23, which is normally closed and which is then opened when the sensor of the pallet, for example the swivel bar 11, is actuated.
  • the switch 25 is assigned to the swivel bar on one side of the pallet, the switch 26 to the swivel bar on the opposite side.
  • the switches 25 and 26 When actuated, the switches 25 and 26 not only interrupt the lines 20 and 23, but at the same time they also connect the other line 23 and 20 to a further supply line 27, which in the same way as the supply line 22, supplies a supply voltage for the motor contactors 14 and 15 provides. As a result of this simultaneous changeover, the motor contactor is opened for one direction of rotation, while the motor contactor for the other direction of rotation is closed, regardless of which direction of rotation signal is supplied by the central controller 5.
  • the two motor contactors 14 and 15 are mechanically interlocked relays, which means that the motor contactors can only close when the other motor contactor is open. As long as one motor contactor is closed, the other motor contactor is mechanically locked and cannot be moved into the closed position. This locking is only released when the other motor contactor has reached the open position.
  • Such interlocking contactors are known per se.
  • the central controller 5 sends out a direction signal for a specific pallet, which in the controller 8 assigned to this pallet causes either the coupling relay 21 or the coupling relay 24 to be closed.
  • the associated motor contactor 14 or 15 is activated so that the motor begins to run in the predetermined direction of rotation. This rotary movement is normally ended by opening the corresponding coupling relay again.
  • the swivel bar 11 or another sensor is activated, which opens the switch 25 or 26 in the corresponding line 20 or 23 and thereby opens the motor contactor, although the associated coupling relay continues to go remains closed.
  • the other motor contactor is also closed, so that the motor runs in the opposite direction of rotation, although the coupling relay responsible for this direction of rotation is still open.
  • the resulting reversal of the parking pallet interrupts its movement towards the obstacle and removes it again from the obstacle.
  • the controller By reversing the direction of rotation, the signal present on the originally activated signal line 16 or 17 will disappear and a signal voltage will appear on the other signal line 17 or 16.
  • the controller thus recognizes the actual direction of rotation of the drive motor and can compare this with the direction of rotation that is requested by the central controller 5. In the event of an emergency reversal of the drive motor, the control determines this by the difference between the requested and the actual direction of rotation and thereby generates an emergency stop signal which is fed from the control 8 via the rails to the central control 5 and there for switching off all drives Pallets leads.
  • the circuit elements used for this are not shown separately in the drawing, since they can be implemented in a simple manner by the person skilled in the art.
  • This switch-off of all pallets can be a long time in some cases, namely when the central control is in a state in which no incoming signals can be recognized.
