  • Each rack 1s provided with a reversible motor and 1s mounted on a plurality of wheels at [52] US.
  • This invention relates to a storage rack installation comprising a rank of movable storage racks disposed in lateral juxtaposition and adapted to be shifted sideways individually or in groups by associated drive means to open an access passage between any two selected neighboring racks, each rack being provided with a reversible motor.
  • each rack is mounted on a number of floor and track wheels of which at least some are geared to the associated motor, and in that control means are provided comprising a common control unit which controls the direction of rotation of the motor or motors of the single or group of racks that is to be shifted, by reference to the position of two-way switch means of which one is associated with each rack and which assume a position depending upon the existing position of the rack with which they are associated.
  • H0. 1 is a view of the underside of an individual rack
  • FIG. 2 is a schematic front elevational view of a storage rack installation comprising four individual racks
  • FIG. 3 is a diagrammatic representation of electrical circuitry suitable for operating a rack installation according to the invention.
  • each mobile rack l is equipped with an electric motor 2 which applies torque through a pinion 3 directly to floor wheels 4 and track wheels 5.
  • the wheels 4 and 5 that are mounted on the driven axle are connected by lengths of shafting 6 and coupling clamps 7 and thus operatively connected to the motor.
  • H6. 2 is an illustrative embodiment of a rank of storage racks which comprises four separate racks 10a to Mid so disposed between sidewalls W that the racks can be shifted to and fro by their respective motors to open up an access passage 1i between any two neighboring racks.
  • a passage has been opened up between 10b and 10c.
  • the width of the passage will be arranged to be somewhat wider than the width of one rack. However, this width may be chosen to meet specific requirements.
  • Two pushbutton switches B2 and 13 are provided on the front panel of each mobile rack.
  • Each rack 10a to 10d is further provided with a control member, for instance in the form of a magnetic switch 14, fitted with a bistable changeover contact.
  • the magnetic switches 14 are operable by pairs of permanent magnets N15a-Ni5d and Sl6a-Sl6d, mounted on a fixed guide rail l7 and preferably located either above or behind each rack, the magnets Nl5a-Nl5d operating the contact in the cooperating magnetic switch 14 to start'the motor for shifting a rack that is in its left-hand end position to the right.
  • the magnets S16a-Sl6d operate the contact in the cooperating magnetic switch for shifting a rack that is in its right-hand end position to the left.
  • the magnets Nl5a-Nl5d and Sl6a-Sl6d are located at different levels and relatively spaced across the racks.
  • the said control members i.e. in the illustrated embodiment the magnetic switches 14, may be fixed in a suitable position outside the racks, in which case the racks are each provided with actuating elements for changing over the operative position of the control member.
  • bar-shaped pedal switches 9 which interrupt the supply of current to the motor when their contacts are closed and which are thus adapted to stop the associated group of racks.
  • each rank of racks comprising any desired number of racks, in the illustrated embodiment the rank comprises four units 10a to 10d, is also provided with a common main control cabinet 21 which contains all the apparatus needed for the joint control of the racks in the rank, and which is connected by a multicore cable to the nearest rack 10a.
  • the panel enclosed by a discontinuous line on the left-hand side of the diagram contains the circuitry of the main control cabinet 21, whereas the adjacent divisions separated by dotdash lines represent the control elements contained in the individual racks 10a to 10d.
  • a main switch (not shown) connects the primary of a transformer 24, which for safety reasons transforms the mains voltage to a lower voltage through fuses 23 to the two phases R and S of the mains network.
  • a conductor 25 is connected by contacts 33b and 34b to one terminal a of the secondary winding of the transformer 24. Since it is desired to move the rack 10b to the right the appropriate pushbutton switch 13 on this rack for a shift to the right is briefly depressed. Current from the conductor 25 thus passes through the closed contacts of this switch. Since the magnetic switch 14 of the rack faces the magnetNlSb, the switch blade of the magnetic switch is in position for a shift of the rack to the right. The depression of the pushbutton switch operates a relay 44 having contacts a-f.
  • the relay 44 would release when the pushbutton is released, the relay is self-holding in a circuit beginning at the secondary terminal a of the transformer 24 and closed via the contacts zl and 330, a conductor 26, the closed contact 44b, the relay winding 44, a contact 43f, a contact of the magnetic switch 14 and a conductor 54 which leads back to the other terminal b of the secondary winding of the transformer 24.
  • Closure of the contact 440 also applies voltage via a conductor 30bc to the next rack 100 in which a relay 46 would operate if this rack were likewise on the left of the passage ll.
  • the contact of the magnetic switch 14 in rack 10c is in the position for a shift to the left because this switch aligns with the magnet Sl6c. Consequently the relay 46 cannot operate.
  • an auxiliary relay 34 is energized by a contact Rd which is coupled with the group of contacts R, and which holds in operate position through a contact 34a which is now closed and a break contact 310. Operation of relay 34 removes potential from conductor 25 because its contact 34b opens, so that no other rack can be started up via this line.
  • the time relay Z which is likewise contained in the main control cabinet 21 is merely a safety device for the protection of the motors 2a2d. It is energized via contact Le or Re when one of the contact groups D' or R of the duplex contactor closes and remains in operate position until the said group of contacts opens again.
  • each rack is fitted with a bar-shaped pedal switch 9 which pennits the motor to be stopped at any time. Operation of the pedal switch causes a relay 33 to be energized via a conductor 28.
  • the relay contacts 33a and 33b open and break the holding and control circuits of the relays 4l--48 which therefore return to their release positions and at once stop the rack.
  • the relay 45 By briefly depressing the pushbutton switch 12 on rack 10c for effecting a shift to the left the relay 45 is energized and operates, the contacts 45a-e opening and contact 45f closing. Via contact 45a and conductor 20cb the relay 43 in rack 10b is simultaneously operated so that the relay contacts 54a--e likewise close and contact 43f opens. The two relays 45 and 43 hold in operate position via their respective holding contacts 45b and 43b.
  • a particular advantage of the described control system is that only those switching elements that are specifically associated with each rack need be mounted in the rack, whereas the elements that are common to all the racks are located in a main control cabinet 21. Moreover, if an existing rank is to be extended by the provision of more racks, these can simply be added to the last rack in the existing rank which does not have to be modified in any way because the control means in each rack form a completely self-contained unit.
  • Shiftable terminal racks such as 10a may have to be fitted with two releasing keys 18 and 18. These two keys are then connected in parallel, as indicated in the circuit diagram.
  • the key numbered 18 must be depressed when a passage has been opened between the left-hand sidewall W and the rack 10a and afresh passage is required in a different position.
  • a storage rack installation comprising a rank of movable storage racks disposed in lateral juxtaposition, associated drive means for shifting said racks individually or in groups to open an access passage between any two selected neighboring racks, a reversible motor for each rack, each of said racks being mounted on a plurality of wheels with at least one of said wheels coupled to its associated motor, two-way switch means associated with each rack, control means for said motors comprising a common control unit determining the direction of rotation of the motors of the single or group of racks that is to be shifted upon reference to the position of said switch means and said switch means having an open or closed position depending upon the existing position of the rack with which they are associated.
  • each two-way switch means is associated with two relay sets alternatively operable according to the position of said twoway switch means.
