Definitions

  • the invention relates to an apparatus and method for unloading dry, semi-dry, or wet materials stored in flexible and rigid bulk containers.
  • Another solution is to store and transport bulk materials in small sacks that are emptied by hand. This is undesirable because of the hight labor cost involved and danger to personnel in the form of back injuries. Also, the one-shipment bag is destroyed in a single use.
  • the invention is an unloading apparatus that satisfies these needs.
  • the unloader can employ a rear tilt mechanism and restraint mechanism that permits tilting in the direction opposite the discharge so that uncompacted material will not flow out of the discharge before it is connected to a hopper.
  • the unloader may also employ mechanisms for squeezing or massaging the sides of a side discharge bulk container to assist the un-compacting process.
  • the unloader may also employ mechanisms for holding or manipulating the side-mounted discharge to assist the flow of materials.
  • the mechanisms can be manually or automatically controlled, and use hydraulics, pneumatics,or electric devices.
  • unloader embodiments can be provided with any combination of the operating systems disclosed herein to ensure that it will be capable of effectively handling and discharging a wide variety of materials.
  • Some of the material include brown sugar, carbon fiber, cellulose powder, chopped fiberglass, and pigments. In almost all cases, only one or two of the systems will be used for a specific application.
  • control systems and logic circuits When selecting unloader features for specific applications, the appropriate control systems and logic circuits will also be chosen. As part of the overall hydraulic, pneumatic, or electro-mechanical package, some systems will require automauc operation, using solenoid valves and PLC's, as well as manually controlled valves. One will not be limited to having only automatic or manual controls. The manually operated overrides will give this capability. The selection of the controls and particular features needed for a particular embodiment is within the ability of a person having ordinary skill in the art.
  • a substantially rigid platform 16 is provided that is preferably rectangular in shape and sufficiently large to accept a standard sized pallet 25 that supports a bulk material container 24 and other unloader structures.
  • the footprint of the container 24 is approximately the same as the load area of the pallet 25, and is typically shaped approximately like a cube.
  • the unloader is adapted to unload side-mounted discharge bags as disclosed in U.S, Patent No. 5,344,048, although the apparatus may also be used to unload rigid containers and containers without side-mounted discharge mechanisms, e.g. , spouts 35.
  • Such bags may also employ pleats 36 that expand the volume of the bag when fastoned from the side of the bag.
  • Flexible bags 24 are often provided with straps at the top corners which, when used when the bulk material unloader of the present invention, help to hold the bag 24 in place on the platform during the unloading process.
  • at least one front and back vertical support post 17 and 18 are provided and are secured near the four corners of the platform 16, and are spaced widely enough apart to permit loading a pallet 25 onto the platform 16.
  • the support posts 17 and 18 are at least as tall as the bag, and may also employ strap securing mechanisms at their top ends, like hooks and bars.
  • the platform 16 rests on a substantially rigid frame 14, and may optionally be fastened to the frame on one side by a hinge 15 depending upon the particular embodiment.
  • the frame 14 serves as a fastening mechanism to secure any of the unloading mechanisms described below, and is preferably made of structural steel.
  • a screw feeder assembly 13 secured to a front end of the unloader frame 14.
  • the screw feeder assembly has a hopper 10 having a flange 11 for attaching the bag spout 35 for receiving bulk material discharged from the bag 24,
  • the screw feeder is driven by a motor 12, and moves material from the hopper to a suitable input point of an industrial process.
  • a screw feeder is shown, other material conveying mechanisms may be used, including belt conveyors and bucket conveyors. Their selection and use of these and other equivalent mechanism is well known to those skilled in the art.
  • Certain materials may not always cake up into a solid mass when shipped in the inflatable bag. Some of the material may remain in a powder and flowable condition. Because the front pleat of the bag must be opened up to allow the spout of the bag to be connected to the inlet flange of the unloader, the platform must be tilted backward to a sufficient angle so that no dust or material leaks out of the bag during this operation. Hazardous materials like herbicides, lead powder, fertilizers, and chemicals, as well as non-hazardous materials that may be dusty or require being handled in a contaminant-free environment, will require this feature. It is not possible to secure the spout of the bag to the inlet flange of the hopper without opening the sidewall pleat on the bag for diameters above around 50 cm. The spout is just too big.
  • this function is preferably controlled automatically with the press of a button.
  • the operator prior to activating this system for the rear tilt feature, the operator must attach a bag restraint harness 23 around the back of the bag and secure it ot the bag restraint coupling 21, which is secured to a bag restraint post 20 fixed to the platform 16, and pull the bag restraint harness 23 tight.
  • the bag restraint coupling is preferably spring loaded.
  • the bag restraint harness limit switch 32 is energized. If the bag restraint harness limit switch 32 is not energized, the rear tilt feature will not function.
  • a light or some type of warning device may be used to inform operator of the situation.
  • Use of the limit switch is a safety feature, and an unloader can be provided without it for manual control.
  • a linear displacement mechanism 33 will extend to its maximum stroke, about 3 cm above the elevation of a rear support frame 26.
  • the rear support frame is not necessary for this invention, but may be provided as an option.
  • the linear displacement mechanism 33 is preferably a hydraulic cylinder, but could also be a pneumatic cylinder, power screw, or other mechanism known to those skilled in the art.
  • a rear support frame hydraulic cylinder 34 extends to its maximum stroke causing the rear support frame 26 to tilt backwards as it pivots on the rear frame support pivot pin 27.
  • the rear support frame hydraulic cylinder could also be a pneumatic cylinder or power screw mechanism.
  • the platform linear displacement mechanism 33 is activated to allow the bag platform 16 to tilt down and come to rest at the platform linear displacement mechanism's 33 minimum stroke position.
  • the platform linear displacement mechanism 33 extends to its full stroke position, raising the bag platform 16 about 3 cm above its horizontal or rest position.
  • the rear support frame linear displacement mechanism 34 retracts, moving the rear frame support 26 back to its vertical position.
  • the rear frame support 26 comes to rest against a platform stop 28 and energizes a rear support frame limit switch 29.
  • the platform linear displacement mechanism 33 can begin to retract so that the platform 16 will come to rest on the rear support frame 26.
  • platform studs 30 interface with rear support frame stud openings 31 to lock both frames into position.
  • an alarm device should be used to alert people in the area.
  • An alarm beeper similar to the type used on a fork truck may be desirable.
  • the rear support frame also acts as a safety guard for the bag when the platform is in the down position. Emergency stop buttons may be employed to stop and hold components in place when activated. Manual valve overrides may not be neccessary.
  • the "Down" function is preferably completed in 15 - 24 seconds, and the suppon frame linear displacement mechanism 33 may be double-acting.
  • a linear displacement mechanism can be a hydraulic cylinder, pneumatic cylinder, or power screw mechanism.
  • the bag 24 Before the "UT" manual lever control can be used, the bag 24 must be secured on the bag platform 16 so that it does not slide forward as the dumping cycle begins.
  • the bag 24 is equipped with cable restraint loops 37.
  • the operator passes the free end of a restraint cable 41 through the restraint cable loops 37 that are affixed to the back of the bag 24.
  • One end of the restraint cable 37 is permanently secured to the side of the bag platform 15.
  • the other end of the restraint cable 41 is equipped with a cable coupling ring 40.
  • the operation of the platform linear displacement mechanism 33 may be operated manual lever controls, or may be automatic. In the majority of situations, the material remaining in the bag will be discharged into the unloader's hopper by simply inclining the bag platform 16. The operator may want to "dump" the contents of the bag incrementally or all at once. An “UP” lever will control the dumping action and a “Down” lever will allow the platform linear displacement mechanism 33 to retract, lowering the bag platform 16 to its horizontal position.
  • the linear displacement mechanism needs to be single acting for the up motion only.
  • the bag massage system is to be operated independently of unloader features, and it should normally to operated when the bag platform 16 is in the horizontal position.
  • the volume increase in the bag 46 will provide space for the material to move to as force is applied to the sides of the bag 24.
  • Massage paddles 44 will exert pressure to the sides of the bag 24 as the massage linear displacement mechanisms 45 are activated.
  • the bag massage frame 43 is designed so it can be moved back and forth along the bag platform 16. Once in the desired location, it will be locked into position.
  • the bag massage frame 43 is also equipped so that each vertical column can rotate, providing different push angles to the bag 24 as well as allow the massage linear displacement mechanisms 45 to slide up and down the vertical columns of the bag massage frame 43.
  • the massage linear displacement mechanisms 43 may also be adjusted to alter that push angle from perpendicular to the side the bag 24 to any oblique angle.
  • each massage linear displacement mechanism 45 can be locked into that position. While the massage linear displacement mechanisms 45 push angle may be at right angles to the bag 24, it may be desirable to angle the massage paddles 44 inward towards the front of the bag 24 so that the material in bag 50 towards the hopper 10 will be acted upon first.
  • the top bag loop restraint 49 shows how the top loops of the bag are suspended. This design allows the operator to attach all of the loops of the bag from only one side of the bag while standing on the platform.
  • the bag while holding the bag 24 up, the bag is free to slide and move along the top bag loop restraint 49 while the bag massage system is operting. Fixed top loop restraints could cause tears or other damage to the bag 24 if held too firmly in place.
  • Fig. 9 clearly illustrates how the inward movement of the massage linear displacement mechanism 45 and massage paddles 44 will push inward against the sides of the bag 24.
  • the bag restraint harness 23 may be used to prevent the bag 24 from moving backwards as force is applied.
  • each linear displacement mechanism should be controlled by a manual lever and independent of the other.
  • Linear displacement mechanisms are preferably double acting to provide the required pushing and retracting action.
  • the first massage paddle 44 to be operated will simply come to rest against the bag before applying pressure. It will be only after both massage paddles 44 come to rest against the sides of the bag 24 that one or both linear displacement mechanisms may be used, either in tandem or one at a time, that force may be applied. It is important that the bag remain stable and in the center of the paddle to its full stroke would result in moving the bag and possibly causing damage to the bag.
  • the pushing speed should be adjusted for fairly slow movement so that no sudden jerks could damage the bag.
  • the double inflatable liner bag design will reduce the need for this system (it will provide a more deliberate and targeted function from inside the bag).
  • An alarm horn/beeper can be used with this system.
  • the material in the bag may be caked and compacted to a point where it will not flow.
  • low pressure air can be introduced between the sidewall of the bag and an interior liner. As air enters the space between the two, the interior liner expands. As it expands, the material begins to fracture and is eventually pushed towards the hopper. It is important that the entire brick of material is not discharged all at once. First of all, the hopper will not hold the volume, unless designed that way deliberately, but more importantly, it would create problems in the hopper and cause flow problems in the conveyor. The concept is to supply the hopper with small increments of material, just enough to keep the conveyor flooded so that no interruption in flow occurs.
  • While flow-aid devices can be installed on or in the hopper to help agitate the material and keep it moving, low head pressure is ideal. It helps prevent flow problems from occurring.
  • a low level sensor or probe intalled in the hopper will constantly monitor the level of material over the conveyor. As the level drops below a preset level, a blower will come on, thus inflating the liner in the bag, until the probe detects the presence of material. The blower will go on and off many times in response to the probe until the contents of the bag are emptied.
  • One embodiment can be equipped with two blowers. One will be dedicated for inflating the bag only, while the other be used for other flow-aid devices, or use in tandem with the primary blower.
  • the material 50 in bag may be discharged.
  • the probe 57 will sense that the material level needs to be replenished, and a blower system 51 will be activated immediately.
  • the probe 57 will switch the blower system 51 off.
  • the air between bag wall and the liner 61 will increase in volume.
  • the inflatable liner 55 will continue to expand, breaking up and pushing the caked material.
  • the material being discharged 50 breaks up further as it falls into the hopper 10.
  • An air filter 59 can be provided as a component of the blower system 51 to ensure the supply of clean air to the blower.
  • the bag When the inflatable liner 55 is fully expanded signifying that the bag contents have been discharged and the bag is empty, the bag will rend to acquire a round shape as it nears full inflation and the corners of the bag 24 nearest the platform will rise above the platform. This rise will provide the automatic control system the means to turn the system off.
  • An end clip 64 with a cable 63 will be attached to a back floor wall seam of the bag 24. As the bag 24 rises at full inflation, the cable 63 will pull inflation limit switch 62.
  • a timer may also be used to turn off the blower. For example, if the blower runs constantly for more than one minute, the system shuts off. In any event, a maximum time limit will be part of the control system. If the blower were to be left on continuously the heat produced by the blower could because a serious hazard.
  • the probe and blower system could be equipped with both automatic and manual controls.
  • a single button pendant switch can be provided for jogging the blower during test and actual operating conditions The operator may monitor the first few inflation blasts to make sure the material is breaking up and beginning to flow.
  • the automatic controls can be turned on once the operator determines the brick of material in the bag has been sufficiently fractured.
  • a limit switch can be mounted on the inlet flange of the hopper that will sense the presence of either the cover or bag clamp ring.
  • a hopper inlet opening 67 typically has several bars running across it from side to side, it remains a safety concern when uncovered.
  • a hopper cover 100 is provided to allow the material conveyor to continue running, supplying material to production, when the bag 24 is not attached to the inlet flange of the hopper 11.
  • a hopper inlet opening limit switch 65 is positioned on the inlet flage of the hopper 11 and will sense the placement of either the hopper cover 100 or the bag clamp ring 66. If either the hopper cover 100 or the bag clamp ring 66 is not in place, the material conveyor 13 will not operate.
  • the hopper inlet opening limit switch 65 will provide the means for controlling the material conveyor drive and motor 12 when the hopper opening 67 is uncovered.
  • the hopper cover 100 is designed to be folded in half by a hinge 68 when in its stowed position at rest on a cover support frame 102. Handles 104 will allow the operator easy and handling of the hopper cover 100. By folding the hopper cover 100 in half for stowage, the underside or contact surface is likely to remain clean and contaminant-free. Material dust from the hopper 11 will remain entrapped in the folded hopper cover 100.
  • the hopper cover 100 by stowing the hopper cover 100 in a folded position, it is less likely to fall, causing injury to fingers, and other appendages, and provides casier handling with the two cover handles 104 provided. It also assumes a lower profile and is away from other components.
  • Figs. 16 - 17 illustrate how a discharge connection flange 70 can be provided to pivot downward as the bag platform 16 is inclined. This feature ensures that the discharge spout of the bag 24 remains in an open and taut position dunng the dumping action of the unloader.
  • the discharge connection flange 70 is not directly linkedt to the platform 16.
  • a flange arm 72 is fixed to the discharge connection flange 70 so that it rotates at a pivot joint 71.
  • a wheel 73 is fixed at the end of the arm 72 and rolls along a platform flange 74 as it moves up and down.
  • the arm 72 can contact the platform flange 74 by sliding or even be rotatably connected as with a linkage.
  • the movement of the platform 16 controls the movement of the discharge connection flange 70.
  • the discharge connection flange 70 may be held in place or held upward, even though the platform 16 is moving. Gravity pulls the discharge connection flange 70 down, but is allowed to fload so as not to cause injury.
  • a flexible housing 75 is connected between the discharge connection flange 70 and a discharge hopper 76.
  • a probe 81 is generally located in the discharge hopper 76.
  • the spout of the bulk bag 24 is connected to the discharge connection flange 70.
  • the flexible housing 75 may be made of either a coated fabric or a breathable fabric or of any other suitable flexible material well known in the art. If the discharge connection flange 70 was fixed, the spout of the bag 24 could wrinkle and cause an interruption in flow as the platform 16 inclines. Upright supports 17 hold the top support strips of the bag in place.
  • a linear displacement mechanism 33 is used to incline the platform 16.
  • Figs. 18 - 19 show the use of a front support bar 77 attached to the iront upright support posts 17a and 17b. This component is helpful in supporting the bag 24 and material inside during the dumping operation.
  • the front support bar may be of any size and may be adjustable and removable.
  • the platform 16 may be inclined to its maximum angle position. In this configuration, a level sensor and automatic control of the incline action would not be neccessary because the material inside the bag 24 would simply all flow out by gravity.
  • the front suppport bar 77 would help support the load of material in the bag 24. Typically, this use would normally involve free-flowing material only.
  • adjustable plates 78 Located at the top of the vertical support posts 17a opposite the operator platform 78 side are adjustable plates 78 that have a series of holes to provide a variety of placement options for inserting bag support bar 82 from an operator platform 78 side of the unloader.
  • Vertical support posts on the operator platform 78 side 17b are equipped to be easily adjustable up and down.
  • the end of a sliding posts 83 are equipped with locking ends to hold bag support bars 82 securely in place. This design ensures that the bag support bars are locked in place so that the bag is secured during the discharge operation.
  • the unloader frame 14 may be equipped with an operator platform 78, ladder 80 and safety guard rail 79 in one embodiment.
  • Figs. 20 - 22 refer to how any unloader embodiment can be provided with a variety of mechanical massage arm and paddle systems to help break up caked material so that it will flow out of the bag 24.
  • Fig. 20 is a front view of the unloader embodiment illustrating this feature.
  • Massage arms 85a and 85b pivot and are mounted to the platform 16 by mounting brackets 87a and 87b.
  • At the top end of massage arms 85a ana 85b are located paddles 88a and 88b. Because many bulk materials bridge, cake, compact and generally react differently from one another, a variety of paddle designs may be used. Also, the paddles may be mounted rigidly or be allowed to rotate slightly and move as they come in contact with the bag 24.
  • a linear displacement mechanism 86 is mounted at the bottom of massage arms 85a and 85b.
  • the size, placement and number of massage arms may differ according to each application. The goal is to have the massage arm system help break up caked and compacted material in the bag so that is can be discharged more efficiently.
  • This scissor type action equalizes the effect of the paddle system so that the bag is not pushed to one side or another. Independently operated massage paddles could cause operating problems by pushing from one side only providing equal pressure on both sides at once.
  • Fig. 21 shows the side view of an unloader embodiment illustrating this feature. Shown are two massage arm systems 89 and 90. A first massage arm system 89 is positioned lower while a second massage arm system 90 is positioned higher. While a number of placement options may be available, this placement for two systems is preferred when the shorter paddle system 89 is positioned towards discharge spout 92 side of the bag 24. Mouting brackets 91 can be mounted directly to the platform 16.
  • Fig. 22 is a side view of the discharge spout 35 section of the bag.
  • a flexible pan 93 may be used to provide support to the discharge spout 35 of the bag during discharge.
  • a linear displacement mechanism 94 with an end paddle 95 may be used to agitate the discharge spout 35 of the bag to induce material flow.
  • the flexible pan 93 will also prove helpful when a poly liner is employed with a bulk material container with or without the discharge spout 35. There will be applications where a poly liner defines the primary spout when the bulk material container is a rigid bin or gaylord container and not a bag.
  • the flexible pan 93 is very useful whether the linear displacement mechanism 94 is operated automatically or manually.
  • the spout 35 is connected to the discharge connection flange 70 by securing a bag clamp ring 66 around exterior of discharge spout 35 of the bag 24.
