Description

BRIEF SUMMARY OF THE INVENTION

According to an embodiment of the present invention, a bulk bag material conditioner system includes a main conditioner frame and bulk bag pivoting conditioning assemblies, preferably two bulk bag conditioner assemblies. The bulk bag material conditioner also typically includes a safety system and lift assembly.

The bulk bag pivoting conditioning assemblies are typically hydraulically driven and fixably mounted to the cross supports of the main conditioner frame such that when the hydraulic cylinder is activated to actuate the bulk bag pivoting conditioning assemblies the bulk bag pivoting conditioning assemblies pivot about a fixed point where they are attached to the cross supports of the main conditioner frame and rotate upward in an arcuous/curvilinear manner until an amount of pressure, typically an (adjustable) predetermined amount of pressure is supplied on the bulk bag and/or until the assemblies have traveled a predetermined distance. The appropriate amount of pressure supplied to both sides of the bulk bag can be determined or predetermined based on the material to be conditioned in the bulk bag. Typically, the assembly contacts the bag at different predetermined heights on opposite sides of the bulk bag.

The lift assembly elevates or lowers (when appropriate) the bulk bag when the bulk bag contacting pivoting conditioning assemblies are disengaged from the bulk bag. Thereafter, the bulk bag pivoting conditioning assemblies are then activated and actuated to contact a different location on the opposing sides of a bulk bag. Another embodiment of the present invention incorporates a manual or powered rotary turntable as an element of the lift assembly or place on the lift. The bulk bag is placed on the rotary turntable prior to conditioning. When in use, this allows the conditioner to contact any surface of the bulk bag. Typically the bulk bag is conditioned on two opposing surfaces, the rotary turntable rotates the bag 90° and the opposite surfaces are conditioned (again at any number of predetermined heights and locations along the bag, but typically within the range of 1 to 12 different heights and/or locations (more typically between one to three different heights and/or locations) along the height of the outer surface of the bulk bag). The bulk bag pivoting conditioning assemblies of the present invention allow for a significantly decreased footprint on a work floor. Typically, the footprint of the bulk bag material conditioners of the present invention have dimension of about 115 inches wide from the edge of one cylinder guard to the other (these elements project wider than the feet of the assembly by about 12-13 inches); a height of about 102 inches and a depth of about 72 inches. Additionally, in contrast to known bulk bag conditioners that utilize compacting frames that apply opposing forces directly opposite one another in a linear or substantially linear fashion, the bulk bag material assembly of the present invention does not apply substantial downward force on the assembly via the material in the bag when the conditioners are engaged, but instead force the material upward in the bag while conditioning the material due to the upward arcuous motion of the bulk bag pivoting conditioning assemblies in operation. This alleviates the significant downward forces associated with previous designs incorporating conditioners that contacted bulk bags in an opposing linear fashion.

These and other features, advantages, and objects of the present invention will be further understood and appreciated by those skilled in the art by reference to the following specification, claims, and appended drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

According to an embodiment of the present invention, a bulk bag material conditioner 10 includes a main conditioner frame 12, two bulk bag pivoting conditioning assemblies 14, a safety system 16, a lift assembly 18, and a computer or other control mechanism for automating one or more of the various functions of the bulk bag material conditioner.

The main conditioner frame 12 typically includes four base members 20 connected to another to form a substantially rectangular base formed by their engagement. Alternatively, the base members each engage two upwardly extending members 24 at the corner of the substantially rectangular base. If the base members connect to one another, the upwardly extending members may be affixed to the top surface of the base members. More typically, however, the base members engage the surface of the upwardly extending members as shown in FIGS. 1-2. Typically the upwardly extending members include feet 22 engaged to the bottom surface of upwardly extending members 24 that engage the factory or work surface floor. Each of the feet typically includes an aperture through which the feet, and thereby the entire bulk bag material conditioner, can be permanently or temporarily affixed to the surface of the factory or work surface. Additionally, interconnecting each of the upwardly extending members are cross supports 26. The main conditioner frame components are typically metal and engaged to one another via a weld or other similar engagement method. However, the component could conceivably be bolted to one another as well. The main conditioner frame 12 forms a substantially cubic or rectangular prism shaped structure. Additionally, the main conditioner frame may optionally include stationary or removable fork tubes/pockets 28 that operate to receive the tines of a forklift. When utilized, there are typically two such fork tubes/pockets incorporated in the typical bulk bag material conditioner.

The bulk bag material conditioner, according to an embodiment of the present invention, also typically includes bulk bag pivoting conditioning assemblies 14 engaged to the main conditioner frame 12. The bulk bag pivoting conditioning assemblies 14 typically include a conditioning arm mounting plate 41, generally U-shaped, typically planar, or substantially planar, hydraulic cylinder supports 30, a cylinder guard 32, one or more (hydraulic) manifolds 34, hydraulic cylinders 36, fixed shafts 38, shaft cover plates 39, four bolt flange bearings (two per arm) 40, a conditioner arm weldment 42, a removable shaft 46, a hydraulic cylinder engagement bracket member 48, and a shaft cap 50.

As shown in the various figures, the cylinder guard 32 bolts to the main frame assembly, which engages the opposing cross supports 26. Preferably, there are two hydraulic cylinder supports and two hydraulic cylinders in use, however, depending on the material being conditioned or the needs of a user one or a plurality of hydraulic cylinders and therefore a corresponding number of hydraulic cylinder supports may be utilized. The cylinders are sized depending upon the material being conditioned with larger cylinders used for more difficult/harder material to be conditioned and are typically pre-attached by the user based upon the material or range of material types to be conditioned. The cylinders typically have a 2-5 inch bore, more typically they have a four inch bore, and ten inch stroke.

The uppermost fixed shaft 38 on the bulk bag pivoting conditioning assemblies engage the two opposing conditioner arm weldments 42, which are themselves engaged to the conditioning arm mounting plate engaged to the cross supports of the main frame assembly. Typically this engagement further utilizes four (two per arm) bolt flange bearings for facilitating pivoting action about this pivot point when the hydraulic cylinders are activated. The hydraulic cylinders engage the hydraulic cylinder supports 30 and the hydraulic cylinder engagement bracket member 48, which is itself engaged to the conditioner arm weldment, typically by a weld. The bulk bag pivoting conditioning assemblies also typically include two additionally fixed shafts 44 spaced on opposite sides of the hydraulic cylinder engagement bracket member and a removable shaft positioned distal to the portion of the bulk bag pivoting conditioning assemblies that engage the main conditioner frame. Preferably, shaft caps 50 are engaged to the outside surface of the conditioner arm weldments at the distal end 43 of the conditioner arm weldments 42 as well. The shaft(s) that engage the bulk bag material are typically cylindrical, but could be shaped or constructed with added elements to differently contact the bulk bag. For example, the shaft might have a rectangular, square, triangular, oval, or star-shaped cross-section instead of a circular cross-section. Further examples include a non-linear shaft such as a wavy shaft and/or a shaft with a rounded paddle. Additionally, a shaft with a round and/or pointed attachment(s) engaged with the shaft could be used in any combination of the above cross-sections, shaft types and/or attachments could also be made.

The hydraulic system 100, which operates the hydraulics of the present invention, preferably uses a 10 horsepower and two (2) 5 GPM (gallons per minute) pumps (the motors and pumps may be differently sized depending upon the application). The system also uses a hydraulic reservoir 106 that also may be sized depending upon the application. A hydraulic mount is also typically used. Typically, the hydraulic system is a Parker® (or other brand) hydraulic pumping unit with the hydraulic reservoir 106, a fluid level sight gauge, an adjustable pressure relief valve, a system pressure gauge, a return line filtration system with spin on element, and twin submerge gear pumps. The hydraulic lines typically utilize stainless steel connectors. An enclosure cover 104 typically is used to cover access to the hydraulic system contained in the enclosure 102. Typically, the hydraulic and power lines within the bulk bag conditioning system include energy chain systems to protect the moving power and electrical connections. One such energy chain system is a nylon energy chain system. The systems operate to guide and protect the hoses, cord, and cables by preventing tangling, corkscrewing, premature wear, and material (dirt) contamination. The cords, cables, and/or hoses or other similar material are spaced within the energy chain system.

The bulk bag material conditioner of the present invention also may optionally include a safety system 16. When utilized, the safety system includes machine guards 29 preferably made out of clear plastic, metal, expanded metal, or other clear shock resistant or shatter proof material. Typically, the clear plastic machine guards are constructed of shatter-resistant or shatter-proof materials. Suitable materials may include flattened-expanded metal guarding, transparent polycarbonate guarding (with continually welded, carbon steel frames), transparent acrylic guarding (with continuously welded, (carbon) steel frames), metal guarding panels and combinations of over or more of the above. Typically, the machine guards are constructed such that they cover all or substantially all of any exposed accessible opening of appreciable size on the three non-loading sides of the bulk bag material conditioners of the present invention. Safety systems would not be necessary if a side was, for example, against a wall or other piece of machinery. Along the fourth side, the load side, there is typically a load side light curtain or other safety device that communicates with the control system such that when the light curtain is broken by any person or other object the bulk bag material conditioner stops. This insures the safety of the worker during operation. The light curtain is typically affixed to opposite sides of the upwardly extending member 24 on the front surface of the bulk bag conditioner. Other possible safety devices that may be used generally and typically on the load side include electrically interlocked doors containing a safety switch that stops operation of the device when the door is opened and through beam photoelectric sensors that similarly stop operations when the sensors are activated. These systems are also typical in communication with the control system of the bulk bag conditioning system.

Additionally, the bulk bag conditioner embodiment of the present invention further includes a lift assembly 18. The lift assembly typically includes a manual or powered rotary turntable 110 and a hydraulic powered lift system having two sets of opposing members engaged to opposite sides of a lift base and a center joint. The lift system hydraulics and elevating structures may be enclosed by a safety bellow (see FIG. 12), which is typically an accordion-style skirt that operates to prevent debris and materials (liquids and solids) from contacting the lift components. One or more hydraulic cylinders are connected to this assembly such that when the hydraulic cylinder is activated, the entire assembly forces the powered rotary turntable and the lift assembly tabletop surface to elevate as shown in FIGS. 3-4 and 7-9. The rotary turntable may be positioned on the top surface of the lift assembly and optionally affixed thereto the deck cover.

While the presently preferred embodiment incorporates the above-described lift assembly to elevate and lower and otherwise position the bulk bag in the appropriate vertical position for material conditioning, Applicants presently believe that the bag may be held at one height and the bulk bag conditioner assemblies mounted in a vertically movable track system such that the bulk bag contacting container assemblies would be vertically adjustable to contact different surfaces along the height of the bulk bag. This configuration however does not readily allow the bulk bag to be rotated. However, Applicants presently believe that it may be possible to keep the bulk bag on a powered rotary turntable that is placed and/or engaged to a stationary surface. In another alternative, the bulk bag could be hoisted or lifted to different positions using a hoist system such as the system described in U.S. Pat. No. 7,223,058, the disclosure of which is hereby incorporated by reference in its entirety. The hoist and material container transport assembly could operate to change the height of the bulk bag as discussed herein as an alternative to the lift assembly.

In the typical operation, as shown in FIGS. 7-9, the control system is contained in the control enclosure 112. When a computer system is utilized, the computer system includes a processor, a memory subsystem coupled to the processor where the memory subsystem stores code that when executed causes the processor to perform one or more of the steps described herein for conditioning a bulk bag. Multiple different sets of commands may be provided by the code to allow a user to execute various different bulk bag conditioning steps utilizing the bulk bag conditioners of the present invention. User input can be received from a touch screen display, push button control interface, or other user input device such as a display and keyboard and keyboard and mouse.

In typical operation a bulk bag, which may or may not be but typically is already placed on a pallet, is positioned on the powered rotary turntable 110 on the top surface of the hydraulic lift system. Typically the hydraulic lift system is capable of lifting the bulk bag at least approximately 48 inches. FIG. 3 shows the bulk bag on a pallet in the initially placed position. FIG. 4 shows the bulk bag being elevated to an initial conditioning position. As shown in FIGS. 5-6, the powered rotary turntable allows a user, via automatic or manual controls, to rotate the material bulk bag to when the bulk bag pivoting conditioning assemblies are in the disengaged position. Conceivably, although presently not preferred, the bulk bag material conditioners of the present invention may be linked to a network and controlled remotely by the user or other computer system or remotely by a user using another computer system that is in communication with the computer system that controls the material conditioner and optionally another machine such as a discharger.

The rotation allows the bulk bag pivoting conditioning assemblies to engage opposing sides of the bulk bag at an infinite number of angles to facilitate thorough material conditioning. Usually, as discussed above, the bulk bag is rotated 90° such that the conditioning assemblies engage opposite sides of the bulk bag 2. However, for example, the bulk bag 2 may be rotated 45° on two separate occasions and the bulk bag pivoting conditioning assemblies activated to engage and condition the bag at multiple locations along the bag. As will be appreciated, this could conceivably happen at any position in the 360° circle of rotation possibly used by powered rotary turntable 110. Of course, while not preferred, the rotary turntable could conceivably be manually driven. FIG. 7 shows the bulk bag pivoting conditioning assemblies engaging the bulk bag 2 at a first point on the height of the bag. While the bulk bag pivoting conditioning assemblies 14 are in operation, proximity sensors 54 communicate with the control device to control the travel distance of the bulk bag pivoting conditioning assemblies. The bulk bag material conditioners also typically include hydraulic pressure sensors that also preferably communicate with the control system. In this manner, the hydraulic pressure sensor and the proximity switches allow customization of the amount of pressure being applied to the material. Harder materials requiring greater force and more delicate materials typically requiring less force. Typically, the bulk bag conditioner assemblies 14 can be fully extended in about 12 seconds and fully retracted in about 8 seconds.

As shown in FIG. 8, once the bulk bag pivoting conditioning assemblies are disengaged the bulk bag can be elevated using the hydraulic lift assembly 18 and the conditioner assemblies 14 again activated to condition a different portion of the bag. As can be seen in FIG. 2, the conditioner assemblies 14 travel a non-linear, typically a curvilinear path. In this embodiment, when the conditioner assemblies travel in the generally upward curvilinear path, the conditioner assemblies apply an inward and upward force to the side of the bulk bag 2. This results in very little downward pressure being applied to the system, which reduces strain on the surface holding the material and lessens the chance that the bag will be damaged or that the bulk bag conditioning system itself will be damaged.

An alternative embodiment of the present invention is shown in FIG. 17. FIG. 17 shows the addition of typically steel generally U-shaped bars 108 and an alternative base frame of base members 20 shown as 20′, which engage bracket members 120 in a tongue and groove manner to form a more tightly compact base framework in the shape of a square around the base of the lift assembly and positioned to prevent or substantially prevent movement, especially rotational movement of the lift assembly.

Finally, the bulk bag material conditioners of the present invention may be utilized alone or in combination or integrated within a bulk bag discharging system such as those systems disclosed in U.S. Pat. No. 7,223,058, the disclosure of which is hereby incorporated by reference in its entirety.

Therefore, it is to be understood that the embodiment shown in the drawings and described above is provided principally for illustrative purposes and should not be used to limit the scope of the invention. Furthermore, it is to be understood that such concepts are intended to be covered by the following claims unless these claims by their language expressly state otherwise.
