Abstract
A rectangular bin for storing and transporting books at a sorting station in a library has a base on wheels with four side walls and a horizontal floor panel movable vertically within the bin. An optical sensor is mounted adjacent the upper rim and is controlled by a control unit such that during a filling mode of the bin, the detection of a book interrupting the beam lowers the floor panel so as to allow further filling of the bin up to the height of the optical sensor and during an unloading mode the operation is reversed. A battery pack is located in a cavity in the front wall and when being charged at a loading station the control unit automatically operates the filling mode and when disconnected the control unit automatically operates the unloading mode. The actuator has two pairs of levers and an electrically actuated screw for moving the floor panel with a lower end of the screw housed in a bottom housing hung below the base.

FIG. 2 is a side elevational I view of the bin ofFIG. 1 . -
FIG. 3 is isometric view showing the bin ofFIG. 1 with the side walls removed to expose the actuation assembly for operating movement of the floor panel. -
FIG. 4 is a cross sectional view along thelines 44 ofFIG. 2 . - In the drawings like characters of reference indicate corresponding parts in the different figures.
- In
FIG. 1 is shown a bin generally indicated at 10 withupstanding side walls 11 and 12, an upstandingrear wall 13 and an upstandingfront wall 14. The side walls are connected together at a base generally indicated at 15. The base carries a pair offixed wheels 16 at thewall 13 and a pair ofcastor wheels 17 at thewall 14. The side walls are connected together to form a rectangular container with an open top 19 defined by aperipheral rim 20 formed by the top edge of each of the walls. At each of the four corners is provided abumper element 21 which fastens around the corner onto each of the respective walls at the corner to provide a suitable bumper for engaging obstacles to prevent damage to the walls. The walls may be stiffened with vertical ribs (not shown) to increase strength while allowing a reduction in gauge of the metal walls to reduce weight. - Each of the
walls wall 14 is defined by an inner sheet 14A and an outer sheet 14B defining therebetween a cavity 14C (seeFIG. 2 ). Within the cavity 14C is located a battery pack schematically indicated 25 and a control unit schematically indicated at 26 for controlling the operation of a device as described hereinafter. Thebattery pack 25 is connected by acable 27 to a charging receptacle 28 mounted on the bin at a suitable location. The battery pack provides power to thecontrol unit 26 through acable 29 and the control unit is manually actuated by switches schematically indicated at 30 throughcable 31. The switches together with indicator lights and the plug or receptacle 28 are mounted on a horizontal top surface of thewall 14 underneath the handle. - Within the bin is provided a
floor panel 32 which is horizontal within the bin and can be raised and lowered from a position closely adjacent theupper lip 20 to a position adjacent thebase 15. Thefloor panel 32 includes four moulded flexible,resilient wiper elements 33 each arranged along a respective edge of thepanel 32 and each forming a lip which wipes over the respective inside surface of the respective side wall. The lip thus prevents any materials such as pages or covers of the book from penetrating between therigid floor panel 32 and the rigid side wall by providing the resilient wiping action which seals the gap there between. On thefront wall 14 is mounted ahandle 34 which includes a paid ofupstanding side legs 35 and atransverse rail 36 extending across the top of thewall 14 above the top edge of thewall 14 so as to provide a hand grasp section by which a manual user can propel the bin across a floor surface on the ground wheels and can control the direction of the bin in movement by steering action using thecastor wheels 17. - As best shown in
FIG. 3 and 4, thebase 15 comprises fourperipheral members 15A, 15B, 15C and 15D arranged along the four sides of the rectangular structure. Themembers 15A and 15C comprises simply transverse structural members of suitable cross section to provide the necessary strength. The members 15B and 15D provide a guide channel for theroller 40 at the bottom of the lever system for lifting thefloor panel 32. - Thus the lever system comprises a first pair of
levers stiffening element 43 which transfer torque between thelevers pivot pin 44 so that each of thelevers panel 32 at one edge of the floor panel and is slidable mounted at the lower end on theroller 40 relative to the side rails 15B and 15D. - Symmetrically the lever system includes a second pair of
levers base member 15A and are slidable mounted at the upper end on tracks 32A and 32B of thefloor panel 32 at the sides of the floor panel. - The
levers levers - The actuation of the lifting is effected by a
screw 51 which is mounted at its lower end on a mounting 52 carried on thebase 15. At its upper end thescrew 51 is attached to link 53 mounted on atransverse beam 54 connected across thelevers beam 54 is rigidly attached to the levers to hold them connected an parallel and also communicates rotational torque to the levers to effect the lifting action. Thebeam 54 is pivoted around the pivot axis of the levers at the pins 48 by thelink 53 which is defined by a pair of lugs 53A and 53 b rigidly attached to thatbeam 54. Thus the upper end of thescrew 52 is located between the lugs at a position spaced away from the axis of thebeam 54 to provide force on the levers rotating the levers about their pivot axis. - The lower end of the
screw 51 at the mounting 52 is carried within abottom housing 55 which hangs down underneath thebase 15. The base is thus closed by the dependinghousing 55 together withpanels housing 55 is narrower than the base and shorter than the base and extends from a position between thefixed wheels 16 to a position spaced away from thecastor wheels 17. The top of the dependinghousing 55 is open into the base so as to allow the components of the lifting mechanism to depend into that housing as required to lower the floor panel to a position closely adjacent the base. - The
link 53 allows the screw to effect the lifting action when the levers are lowered to the bottom position since the links are located at a position above the bottom end of the screw so the screw can effect a pivoting action around the axis of thelevers - An extra pair of lugs similar to the lugs 53A and 53B is provided on the opposite side of the
beam 54 which are attached to an assist spring 53C which provides a spring force tending to resist the weight of books on the floor panel thus reducing the force necessary from the screw. The spring is under compression and the compression of the spring is reduced as the floor panel moves upwardly thus automatically reducing the spring force as the load is reduced and increases as the panel is loaded downwardly. The angle of the lugs on thebeam 54 allows the spring to act at the required angle as thelevers 46 and thebeam 54 lie down in the bottom of the bin as the floor panel moves downwardly. A bottom wall of thehousing 55 may provide an access panel to allow access for repair or replacement of the spring 53C and the screw. - Turning into
FIG. 2 , the control system includes anoptical sensor 60 together with theswitches 30. The optical sensor is arranged to detect the height of books on the floor panel which reaches the optical sensor which is located just below the top rim of the bin. - The
control unit 26 is arranged in response to imputes from theswitches 30, theoptical sensor 60 and the charging connector 28 for the battery pack to control the system as follows. - When the battery pack is being charged by a connection of the receptacle 28 to a power supply at the sorting machine, the control unit switches the system into filling or loading mode in which the floor panel is moved to the upper most raised position. As soon as the optical sensor is obstructed or interrupted by the presence of a book reaching the height of the sensor, the control unit actuates the screw so as to lower the floor panel to a position where the optical sensor is no longer obstructed. This allows further books to be loaded onto the panel and onto books resting on the panel without any of the books having to fall by any considerable distance. This process is continued until the bin is fully loaded so the floor panel is moved to the lowest position or during a period of time so it is partially loaded. When the operator wishes to remove the bin when fully or partially loaded, the power supply to the coupling 28 is disconnected which automatically moves the control unit into the unloading mode.
- In the unloading mode the operation is reversed so that the floor panel is moved upwardly until the optical sensor is obstructed and then the floor panel halts at this position to allow books to be remove by the operator. As soon as the optical sensor is exposed because the books have been removed from that area, the control unit operates the screw so as to raise the floor panel until the optical sensor is again obstructed by the presence of further books.
- The optical sensor may have a receiver on the opposite side or may have a mirror on the opposite side for a transmit receive system and in the embodiment shown, a mirror is indicated at 62.
- The
switches 30 include a first switch providing an on/off action shutting off the control the unit and actuating the control unit. The switches also include a second switch which allows manual operation of the screw to move the floor panel to a position determined by the operator. - Since various modifications can be made in my invention as herein above described, and many apparently widely different embodiments of same made within the spirit and scope of the claims without department from such spirit and scope, it is intended that all matter contained in the accompanying specification shall be interpreted as illustrative only and not in a limiting sense.
