Definitions

  • ABSTRACT This is a storage system having a stacker which may be operated in remote full automatic control or in manually permitted automatic control from the cab on the stacker.
  • the stacker has a pivotal overhead shield to protect the person operating the stacker manually. In the raised position a limit switch is closed which permits stacker moves only when the order picker is on board and holding closed two foot switches and two hand switches. Shuttle operation is restricted to specific'off load points for removal of picked loads.
  • the overhead shield when folded down permits full automatic operation with maximum vertical travel of the stacker and when in the upright position provides means under control of the operator to permit automatic operation of the stacker and protects the operator on the stacker from overhead falling objects.
  • the operator platform on this stacker has an overhead shield which in the upright position permits manual control of the operation of the stacker by the operator while giving the operator overhead protection from any falling object.
  • the stacker cannot be manually controlled by the operator unless the overhead shield is in the full upright position.
  • the shield operates a switch which permits automatic operation of the stacker but restricts an operator from riding on the platform.
  • the stacker cannot be operated unless the overhead shield is in the full upright or the full lowered position, thus preventing inadvertent dual control of the stacker.
  • FIG. 2 is a view showing the operator platform with its fold down overhead shield and its relationship to the material platform.
  • FIG. 1, 2 illustrates the bin arrangement for storing material mounted on pallets utilized in one embodiment of the present invention.
  • the bin 4 is the aisle between the bin structure 2 and a neighboring bin structure, while 6 illustrates a stacker which travels in the aisle 4.
  • the stacker 6 is carried between aisles by a transfer cart 8 which travels on rails 10 extending transverse to the aisle.
  • the bins shown generally as 2 have a series of shelves or bin structures 12 and 14 suitably spacedto support the material 16 being stored therein.
  • the stacker 6 is supported on wheels 18, 20, 22 and 24 which operate on rails 26 and 28 in the aisle 4.
  • the stacker vehicle 6 has a vertically movable cab structure shown generally as 7 having a laterally movable materi a] support platform 30 and an operator cab adjacent this material platform 30.
  • the material storage system 'thus far described with the exception of the cab structure shown generally as 7 is of the type shown and described in U. S. Pat. No. 3,503,530 Burch et al., referred to above.
  • the vertical moving structure 7 carriedby the stacker 6 is shown in greater detail.
  • 30 is the load carrying platformused to deposit and retrieve the material 16 (shown in FIG. 1) from the bins of the storage system.
  • 31 is the stop against which the material is located to assure the material being in the proper position for deposit in the selected storage bin.
  • 32 is the operator platform used: for manual control of the stacker for individual order picking from the bins of stored material.
  • the cabinet 34 contains the electrical equipment which is actuated by the manual controls 63 and 36.
  • the operator is protected by a pivotable shield 38 having an overhead shield portion 40 which folds down and rests on the operator platform 32 when the storage apparatus is operated in automatic control. When the overhead shield is folded down, the
  • the present invention is particulatly related to the operator cab construction shown in FIG. 2.
  • the load carrying platform 30 is of the type shown and described in the above-mentioned patent.
  • the operator platform 32 with the fold down overhead structure permits the stacker to be operated in auto matic control with maximum vertical travel of the stacker.
  • the overhead guard When the overhead guard is in the folded down position, as shown in dotted lines at 46, it lies on the operator platform and discourages anyone from riding on the platform by restricting the space.
  • the operator may stand the switches 63 on the platform 32 and permit operation of the stacker by closing the switches on the controls 36, as will be described later, so that the stacker may be operated automatically.
  • the guard having an overhead shield section 40 and a back shield section 38 is pivoted at 42 to the frame 44 to permit its being moved to the position shown in dotted lines 46.
  • the telescopic shield support column has a portion 54 which telescopes into the column 56.
  • a locking pin mechanism 52 together with the shield support column 44 holds the overhead shield 38 and 40 in the manual control position shown in solid lines.
  • the switch 48 is actuated to prevent automatic operation of the stacker unless the manual control switches 63 and 36 are 'closed.
  • the shield is in the folded down position for automatic operation, as
  • the switch 50 is actuated which energizes the automatic controls, bypassing switches 63 and 36. It may, therefore be seen that the stacker may be controlled manually only when the overhead shield is in the full upright position and the switch 48 is actuated to energize the manual controls 63 and 36. The stacker may be operated in automatic control bypassing controls 63 and 36 when the shield is in the fully folded down position 46 and the switch 50 is actuated to energize the automatic controls directly.
  • the material storage system shown in FIGS. 1 and 2 may be operated in automatic control 'as shown and described in the abovementioned patent when the cab is in the folded down position, as shown in FIG. 2.
  • the switch 50 When the cab is in'the folded down position, as shown in FIG. 2, the switch 50 is closed and this bypasses switches 62 and 36 to energize the automatic controls directly by the actuating arm 58 of the switch engaging the telescopic support column 56.
  • the transfer car 8 When the automatic controls are actuated, the transfer car 8 carries the stacker 6 on the rails 10 to the proper aisle 4, after which the stacker 6 travels off of the stacker 8 on the rails 26 and 28 to deposit or retrieve material 16 from the bins 12-13 by actuation of the lateral platform 30, as is described in the above-mentioned Burch U.S. Pat. No. 3,503,530.
  • material 16 When material 16 is placed on the load carrying platform 30 forlatervdeposit on the bin rails 12-14, it is located against the pivotal locating member 31 to assure its proper location for depositing on the rails 12 and 13, which comprise the storage bin.
  • the operator'protective shield is positioned in the folded down position 46 so as to actuate the automatic control switch 50 by mechanical movement of the actuating arm 58 by the column 56.
  • this overhead shield is raised into the upright position.
  • the switch arm 58 disengages the column member 56, the switch 50 is opened, thus de-energizing the automatic controls for the entire system.
  • This switch de-energizes the entire electrical automatic control system.
  • the overhead shield is'in the full upright position, the locking pin 52 is inserted to lock the members 38 and 40 to the frame 44.
  • the telescopic member 54 is then raised into engagement with the support member 60 carried by the overhead shield member 40 and locked into position.
  • This protective shield is then in position to protect the operator from any object which may inadvertently fall from above.
  • the switch 48 When the shield is in this upright position, the switch 48 is closed by the mechanical actuation of the operating arm 62 of the switch by the member 38. When the switch 48 is closed, the electrical circuits to the manual controls 63 and 36 are energized. The operator may then permit automatic control of the vertical movement of the assembly 7 on the stacker 6 and the horizontal movement of the stacker 6 in the aisle 4. ln addition to these movements, the operator may also through the controls 36 and 63 permit control of the deposit and retrieval material platform 30 to deposit and retrieve the material container 16 from the bin rails 12 and 13.
  • the operator manual controls 36 are located opposite the material platform 30 so that the operators arms must be in a safe position with regard to the load carried on the platform 30 when the platform is being moved and the control switches 63 are so located that the operator must be standing in the proper position on the platform 32. This is to prevent the manual operation of the material load platform 30 with the operators hands on the material or his feet in an improper position, thus promoting safety.
  • the operator by controls 63 and 36 permits the stacker to go to the proper bin to retrieve the load from the bin, the operator then takes the packages from-the load desired for a particular order and then redcposits the load in the bin. This operation is repeated at various I selected bins until the order for a particular customer or group of customers is completed.
  • the operator closes switches 63 and 36 and the automatic control lowers the assembly 7 and operates the stacker 6 up the aisle 4 until it reaches the end of the aisle at the stacker transfer car 8, at which point the stock picker (operator) removes the material for the orders he has filled and then either returns -to the bins to pick further orders or gets out of the cab, folds the overhead shield to the position shown in dotted lines, at which position the manual controls are bypassed and the automatic controls are again effective and the stacker is put back in automatic operation.
  • the stacker may be at the operators option used under operator control for order picking with maximum safety to operator and equipment, or under remote automatic control with the shield folded down to give maximum height utilization of the stacker.
