When the container is used to transport other than bulk materials, bulkhead unit 13 is moved toward the front end of the housing unit to collapse flexible liner I4 and retain it against front end wall 24, as illustrated in FIG. 1. In such inoperative condition, spout unit 50 is positioned in recess 49,
cover panel 70 is mounted across the retracted spout unit, and side panels 51 and 52 are mounted flush with cover panel 70,
i as illustrated in FIGS. 4 and 5. The bulkhead unit is retained in such position by sliding bolt latches 75, 76, 88, and 89, which engage channel strips 39, 40, 41, and 42.
When it is desired to load the container with a bulk material, latches 75, 76, 88 and 89 are disengaged from the channel strips and the bulkhead'unit is moved rearwardly to expand the flexible liner to the operative condition, as illustrated in FIGS. 6-through 8. When the bulkhead unit is moved sufficiently' rearwardly to expand the flexible liner, it is secured in position by means of slide bolts'l58 and 159 mounted on the lower ends of channel-shaped members 44 and of the bulkhead unit, which are received in retaining holes in bottom wall 21 of the housing unit, as best illustrated in FIG. 3. The flexible liner is then fully expanded by connecting each of connecting straps 125. to hook elements 124 and connecting each of connecting straps 127 to hook elements 126. Under such conditions, the flexible liner is fully expanded and conforms to the configuration of chamber 557 It will be noted that tunnel loops I10 maintain top liner section 96 adjacent top wall 24, straps 114 and 125 maintain side liner section 97 adjacent sidewall 23, straps 115 and 127 maintain side liner section 98 adjacent sidewall 22, tunnel loops 107 and 138 maintain front liner section 99 adjacent front wall 24, and tunnel loops 104 and 144 maintain rear liner section adjacent bulkhead unit 13. The straps 142, 143, 118 and 119 further assist in maintaining the front comer portion of the flexible liner adjacent the from upper and lower comers of chamber 55.
With the flexible liner fully expanded as described, side panels 51 and 52 are remounted' on the bulkhead unit, as illustrated in FIG. 3. Side panel 52 is secured in the operative position by mounting abutment members 71 and 72 in channel strips 40 and 42, positioning side panel 52 at an angle relative abutmentmembers 71 and 72, fastening the inner end of the panel to channel-shaped member 45 by sliding the bolts of latches 75 and 76 into the registerable openings in the channel-shaped member, and then pulling spring members 73 and 74 rearwardly and securing the hook ends thereof to channel strips 40 and 42 to urge the outer portion of side panel 52 into firm engagement with abutment members 71 and 72. Side panel 51 is secured in position in a similar manner. Cover panel 71 is then removed from across recess 49.and mounted on the upperend of the bulkhead unit. The rigid spout unit 50 then may be pivoted downwardly out of recess 49 to its operative position, as illustrated in FIG. 3.
The flexible inlet conduits 156 of the liner will register with annular mountings 29 when the liner is in the expanded condition. Theliner then may beloaded with a bulk material merely by lifting cover members 20 to an open position, pulling the flexible conduits upwardly through the annular mountings, unzipping fasteners 157 and inserting a charging conduit 158 through the flexible conduits to charge bulk material into the interior of the flexible liner. When the liner is fully loaded, the charging conduit'is removed, the flexible conduits are closed and folded into the annular mountings, and the covers are closed. The container is then in condition for transporting the bulk material to its ultimate destination.
Upon arrival at its destination, the container is positioned on tiltable platform 18 of unloading unit 11. The chassis is then rigidly secured to platform 18, and hydraulic cylinder assembly 20 is actuated to tilt platfonn 18 and the entire container. Conduit section 63 of spout unit 50 may be connected to a suitable pneumatic conveying system and the bulk matcrial in the flexible liner will be discharged by gravity flow through the spout unit when the valve 64 is opened. As the container is tilted rearwardly to discharge the bulk material, liner portions 102 and 103 engage side panels 51 and 52 which act as baffles, directing the material toward the flexible spout 146. During the unloading procedure, the cover members 30 are secured in the closed position and air is permitted to enter the interior of the flexible liner by means of an air intake conduit 159 intercommunicating the interior of the flexible liner with the exterior, and having a one-way valve 160.
As soon as the bulk material has been unloaded, conduit section 63 is disconnected from the pneumatic conveying system and the hydraulic cylinder assembly is actuated to lower platform 18 to the horizontal position. The spout unit 50 is then pivoted upwardly into recess 49 and cover panel 70 is secured across recess 49 to retain spout unit 50 in the retracted position. Side panels 51 and 52 are then removed from the bulkhead unit, and latches 158 and 159 are disconnected to free the bulkhead unit. The bulkhead unit is then in a condition to be rolled forwardly to collapse the flexible liner and secure it against front wall 25. Connecting straps 125 and 127 are then disconnected from hook elements 124 and 126 to permit the flexible liner to collapse as the bulkhead unit is moved forwardly.
The folding of the flexible liner is facilitated by a plurality of liner draw line assemblies 163 mounted on the ends of hanger rods 11!. As illustrated in FIG. 3, each draw liner assembly 163 includes a pulley unit 164 secured to the end of hanger rod 111, and a draw line 165 having the lower end thereof secured to strap 122 and the upper end thereof reeved about the sheave in the pulley unit 164. It will be appreciated that the free end of the line 165 may be drawn to lift strap 122 and the adjoining liner portion adjacent pulley unit 164. The liner portion then may be retained in the drawn position by securing connecting strap 125 to a hook element 166 provided on pulley unit 164. With spaced lower portions of the flexible liner drawn up by draw line assemblies 163, the bulkhead unit may be moved forwardly toward front wall to collapse the liner and fold it against front wall 25. When the liner is fully collapsed and folded and the bulkhead unit is disposed in its foremost position in the housing unit, as illustrated in FIG. 1, side panels 51 and 52 are remounted on the bulkhead unit to secure the bulkhead unit to sidewalls 22 and 23 of the housing unit by means of latch units 75, 76, 88 and 89. The container then is in a condition to be loaded with other forms of cargo.
