Title: Carousel loading apparatus

Description:
This application claims priority to U.S. Provisional Patent Application No. 61/636,242 filed on Apr. 20, 2012 and entitled “Carousel Loading Machine”, the content of which is hereby incorporated by reference. 
    
    
     BACKGROUND 
     Loading machine systems come in varied forms. For example, some loaders are for inorganic matter (e.g., toys, clothing) while others loaders are for organic matter (e.g., food articles including melons, potatoes, apples, onions, citrus, and the like). These loaders may operate in harsh environments, subject to dust, dirt, heat, long hours of operation, and the like. A carousel loader is a specific type of loader that loads receptacles on a rotating basis. For example, a carousel loader may include a series of bins distributed about a rotating hub.

     An embodiment includes a carousel machine designed to slowly deliver a premeasured weighment of product to a receptacle (e.g., bag, box, sack, container, and bin). The receptacle, such as a bag, may be manually hung on pneumatic bag clamps as the carousel rotates. This may help eliminate jamming of product that normally occurs on existing carousel baggers. 
       FIG. 1  illustrates a carousel loader in an embodiment of the invention. Carousel loading apparatus  100  comprises 8 troughs, two of which are labeled as  120 ,  121 . While the embodiment of  FIG. 1  includes 8 troughs, other embodiments may include  2 ,  3 ,  4 ,  5 ,  6 ,  7 ,  9 ,  10 ,  11 ,  12  or more troughs. Each of the troughs is respectively coupled to a pusher plate, two of which are labeled as  105 ,  106 . Hub  190  (e.g., rotation point, axis, table, bearing, and the like) is coupled to a motor (not shown). 
     In an embodiment the pusher plates are respectively configured to advance within the troughs to distribute loads of food articles into receptacles while the motor rotates the hub and troughs. For example,  FIG. 1  includes 8 troughs in 8 stages (labeled as  1 ,  2 ,  3 ,  4 ,  5 ,  6 ,  7 ,  8  in  FIG. 1 ). Stage  1  includes a fully retracted pusher plate  105  within trough  120 , which has just been loaded with product (e.g., oranges). Bag  110  is empty. Stage  2  shows another pusher plate that is partially advanced and has begun pushing oranges into a bag. Stage  3  shows another pusher plate even further advanced and which has pushed even more product into a bag. Stage  4  shows another pusher plate still even further advanced and which has pushed still even more product into a bag. Stage  5  shows yet another pusher plate that is fully advanced and which has pushed the entire initial single load (which was originally loaded into the trough at state  1 ) into a bag. Stage  6  shows a partially retracted pusher plate and, in addition, that the bag has now been removed after it was fully loaded. Bag clamps  140 ,  141  are now narrowed as compared to other bag clamps (such as those for the trough at stage  1  that are expanded to fully open a bag). Stage  7  includes a more fully retracted pusher plate. Stage  8  includes a fully retracted pusher plate and a newly loaded bag. The bag may have just as easily been removed in stages  6 - 8  instead of stage  5 . Further, the new bag may have just as easily been added in stages  6 - 7  instead of stage  8 . 
       FIGS. 2-5  show varying perspectives of bag clamps.  FIG. 2  shows outer bag clamps  240 ,  241 . These clamps are coupled to a trough that couples to a hanging bag. The trough includes an output end portion where articles are emptied into a hanging bag. The output end portion includes a horizontal planar floor  255  non-orthogonally coupled to sidewalls  256 ,  257  and the floor and sidewalls are all monolithically formed with one another. Because they are monolithically formed, there is no need for screws or seams (e.g., that couple a wall to a floor) that may provide a bacteria harboring environment. Floor  255  includes a maximum width  258 . Bag clamps  240 ,  241  are width adjustable (i.e., can adjust to handle different width bag openings via, for example, arms  245 ,  246 ). Thus, they have a setting that statically (i.e., statically throughout product filling states  1 - 5 ) holds a bag open at a width equal to the maximum width  258  and an additional setting that statically holds additional bags open an additional width greater than the maximum width  258 . Thus, a smaller 1 lb bag may have a small opening which is generally equal to width  258 . However, a larger 25 lb bag may have a larger opening that is centered about floor  255  but nevertheless has a wider opening than width  258 . Thus, the embodiment of  FIG. 2  accommodates both small and large bags and loads. In one embodiment width  258  is about 4.5″; however width  258  is not so limited and in other embodiments width  258  is 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 or more inches. In one embodiment each trough is configured to hold up to 25 lbs of food articles but other embodiments may include troughs for 1, 5, 10, 15, 20, 30, 35 lb loads or more. 
       FIGS. 3-5  further explain an embodiment of bag clamps (where a clamp is a fixator that fixes one item to another and is not specific to any one particular type of fixation device). Such an embodiment includes bag clamps that are configured for adjustable load widths (i.e., differently sized bag openings). The embodiment includes at least two inner clamps  443 ,  444  to expand a bag and at least two outer clamps  441 ,  440  to hold the bag against the two inner clamps.  FIG. 4  shows clamps  440 ,  441 ,  443 ,  444  in a state ready to receive a bag.  FIG. 5  shows clamps  540 ,  541 ,  543 ,  544  in a state ready to receive a bag.  FIG. 5  is just a different perspective than that of  FIG. 4  but still shows clamps  540 ,  541 ,  543 ,  544  in a state ready to receive a bag.  FIG. 6  shows clamps  640 ,  641 ,  643 ,  644  in a state holding a bag. 
     By comparing  FIGS. 4 and 6 , one can see that a portion of the bag clamps ( 443 ,  444 ) (a) move toward one another to couple a bag to the bag clamps (end result shown in  FIG. 4 ), and (b) away from one another to expand the bags to receive (end result shown in  FIG. 6 ) articles (e.g., food articles, toys, etc.). Further, an additional portion of the bag clamps ( 440 ,  441 ) (a) move away from one another to couple the bag to the bag clamps (end result shown in  FIG. 4 ), and (b) towards one another to grip the first, second, and third bags between the portion ( 443 ,  444 ) and additional portion ( 440 ,  441 ) of bag clamps (end result shown in  FIG. 6 ). 
       FIGS. 3 and 4  illustrate a pneumatic actuator/air cylinder  347 ,  447 . When the actuator drives in one direction coupler  342  operates such that clamp arm  348  moves in a direction opposite that of clamp arm  349 . Thus, a space between clamps  544  and  540  is formed to receive a bag portion and a space between clamps  541  and  543  is formed to receive another bag portion. 
       FIG. 7  includes an exchangeable paddle for bag clamps in an embodiment of the invention. In an embodiment the bag clamps each couple to a set of differently sized paddles configured to hold open differently sized bags. Clamp arm  761  may couple to clamp arm  648  to quickly couple paddle  744  to the system. Paddle  744  may be just one paddle in an entire kit of differently sized paddles (e.g., with widths of 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 inches or more). Quick attach coupler  760  helps quickly couple arms  648 ,  761  to one another. 
     Returning to  FIG. 1 , each of the pusher plates advances from a back end portion of a trough, through the trough, and to the output end portion of the trough to distribute the articles into the receptacles (although in other embodiments the push plate may traverse only a portion of the length of trough, table, and the like). Focus (for sake of brevity) is now made on just two representative troughs of the 8 troughs in system  100 . Troughs  120 ,  121  are located opposite one another across hub  190 . Troughs  120 ,  121 , pusher rod  130  (coupled to actuator  131 ) and pusher plates  105 ,  106  are configured to advance pusher plate  106  while retracting pusher plate  105  and advance pusher plate  105  while retracting pusher plate  106  (i.e., pusher plates  105 ,  106  reciprocate with one another). Further, in an embodiment pusher plate  106  is configured to maximally advance within trough  121  when pusher plate  105  is maximally retracted within trough  120 . 
     In an embodiment the motor rotates hub  190  and the 8 troughs through an arching path that is greater than 180 degrees. For example, in  FIG. 1  the arching path is a full 360 degrees but in other embodiments the arch may be 90 degrees, 270 degrees, and the like. By looking at stages  1 - 5 , a pusher plate is configured to advance within the trough to progressively distribute the load of food articles into the bag along multiple locations of the arching path. By “progressive” one sees the bag gradually fill over the series of stages instead of just filling in a rather instantaneous dump of product during a solitary stage. Thus,  FIG. 1  shows progressive article distribution at various points (along and between stages  1 - 5 ) along a 360 degree path. 
     A more general discussion of varying embodiments now follows. 
     Bag materials may be made include varied materials such as, for example, polypropylene, polyethylene open mesh, paper, nylon mesh, and combinations thereof. The bags may be in various styles such as, for example, header bags and the like. Boxes, such as cardboard boxes, may also be filled in various embodiments. Boxes may be handled by the bag clamps. For example, a lid flap of a box (or a sidewall portion of a box) may be secured between the inner and outer bag clamps on both the left and right sides of the box (e.g., a lid flap fits between  441 ,  443  and another lid flap fits between  444 ,  440 ). Thus, a “bag clamp” is just nomenclature and is not limited to bags but is more generally applicable to receptacles. The terms “bag clamp” and “receptacle clamp” are interchangeable as used herein. 
     In an embodiment all product contact surfaces are polished stainless steel (e.g., floor  255 , walls  256 ,  257 ) or food grade plastics (e.g., push plate  205 ). 
     In an embodiment a carousel has variable speeds of operation and may work in a continuously rotating mode of operation. The carousel may be driven by a motor coupled to a slip clutch that will pause rotation of the machine in the event of a mechanical conflict with an object (e.g., product jamming such that a door or chute is no longer operable). A slip clutch may drive a center shaft on a round steel table top to which one or more conveyor troughs are mounted. 
     In an embodiment each conveyor trough has a set of width adjustable pneumatic bag clamps to firmly grip a bag in the open position to receive product. Inner and outer clamps move in unison (i.e., both are moving at at least one specific moment in time) apart and together for maximum bag clamping. Clamping pressure is pneumatically adjustable. 
     In embodiment, various bag clamp paddle sizes (e.g., paddle  744 ) are available such as 1.5″ wide for 1-3 lb bags, 5″ wide for 3-15 lb bags, and 7″ wide for 15-25 lb bags. 
     In an embodiment the carousel loader (a.k.a., bagger) is fed a pre-measured batch of product from a weighing or counting machine. Bags are manually (or robotically) placed on 8 heads (e.g.,  FIG. 1 , system  100 ) by one or more operators (laborers). Filled bags may be manually released and removed from the system by pressing a clamp release button and physically removing the filled bag from the carousel. In another embodiment filled bags are released by using an automatic take-off unit that grabs the filled bag before the carousel releases the bag (this occurs automatically via an operator adjustable take-off cam that contacts a clamp release valve closing the bag clamps and releasing the filled bag to the take-off unit). 
     In an embodiment rotation of the carousel is started by pressing a pushbutton on the control box. An operator manually/robotically hangs a bag via bag clamps on each of the 8 heads in positions  6 ,  7  or  8  (See  FIG. 1 ). In these positions of rotation the bag clamps (e.g.,  140 ,  141 ) are released and closed together so the operator can stretch a bag over the clamps. When raising the bag over the clamps the operator contacts a trigger wand (e.g., wand  250  of  FIG. 2 ) with the back of his or her hand. The wand sends an air pulse to a valve that activates a cylinder (e.g., cylinder actuator  447  of  FIG. 4 ) and pneumatically opens the bag and clamps it in place awaiting product. 
     In an embodiment mounted above station  1  (not shown) is a weighment holding collector that accumulates a discharged weighment form a weighing machine. This collector has opening doors through which product is emptied into a trough. 
     In an embodiment object A ( FIG. 1 ) is a photo-eye that reads if there is a bag on the bag clamps of each of the 8 heads. If there is no bag, the weighment holding collector will not open. If there is a bag and there is product in the weighment holding collector the collector will open depositing a batch of product into a trough. If the weighment holding collector is empty the rotation will stop and system  100  will wait for a weighment to be deposited in the holding collector and the system will automatically restart and resume production. 
     In an embodiment when the conveyor trough at station  1  ( FIG. 1 ) has received a weighment from the weighment holding collector an air switch mounted below the trough will activate via a fixed cam that will send a signal to an air valve feeding one of the 4 air cylinder actuators (mounted in the center of the carousel, one of which is labeled  131  in  FIG. 1 ). The air cylinder consists of a body and rod  130 . In one embodiment the rod extends a maximum of 24″ out one end of the cylinder (see station  5 ) but is able to extend out each side of the cylinder. When the shaft is extended 24″ out one side of the cylinder body (see station  5 ) it is only sticking out 2″ from the other side of the cylinder body (see station  1 ). When a pusher plate is mounted to each end of the cylinder rod then one cylinder performs a pushing operation on 2 conveyor troughs so 4 cylinders operate 8 troughs. When the cylinder is fully retracted in station  1  (opening the full width of the conveyor trough) it is fully extended in trough  121  opposite trough  120  and the pusher plate running on cam follower bearings has extended through the trough pushing the entire product into the open bag. 
     In an embodiment cylinder speed is adjustable via flow control valves. Every cylinder will activate every time directly following top dead center at position  1  (i.e., will begin advancement immediately after stage  1 ). This means that at just past top dead center on position  5  each cylinder will retract so that by the time that trough has reached position  1  the pusher plate is fully retracted ready to receive another weighment. 
     Various embodiments have a number of advantages. 
     An embodiment includes no vibrators to advance product into receptacles. Vibrators are noisy and destructive to components and products. 
     An embodiment includes 8 filling heads as opposed to 6 filling heads. This allows the embodiment to have slower rotation speeds to get the same bags per minute production as a 6 head system operating at a faster rotation speed. Slower rotation speeds translate to longer bag hanging time availability, and longer bag filling times—which results in smoother loading and less damage to the product. 
     In an embodiment there are no lift shafts necessary to raise a tilting floor (lift shafts and tilt floors both require a great deal of maintenance and create a pinch point as a wheel transits a ramp). 
     In an embodiment there are little to no additional parts (other than inner bag clamp paddles) needed to restrict the opening when running a 1 pound bag from a larger bag. Conventional carousels require the operator to add additional pieces to singulate the product when running to a small bag opening on a 1 pound bag (while previously working with a larger bag). 
     An embodiment is easier to clean than traditional carousel loaders because there are few or no gaps in the troughs so there is a little to no accumulation of dirt and wax that other carousels suffer. Further, bag clamps and cylinders are protected from dirt and wax because the trough is a fixed piece (e.g., no raised floor that when raised greatly exposes actuators and the like to dirt and debris). 
     An embodiment provides more versatility on weighment sizes and product sizes. For example, system  100  handles 1 pound bags with ¾″ round product (e.g., small limes) to at least 6″ round products in 25 lb bags (e.g., melons) with only inner clamp changeover necessary (e.g., see  FIG. 7 ). This drastically reduces change over time (between small to large products and vice versa) and hassles. 
     An embodiment is not dependant on gravity (like a tilting floor or funnel opening for the product to move). Thus, flat products move as well as round products. 
     In an embodiment there are no bag feed belts for each trough (which require drive and idler rolls, bearings, belting, drive and idler shafts, motor, chains, universal joints, key stock, set screws, guards, slip ring commutators for electricity dispersion—all pieces translating to additional maintenance, and additional costs). 
     An embodiment includes no reflectors and photo-eyes to read location of a head (end of trough) like some traditional carousel baggers. 
     Further, embodiments are not specific to any one type of counting and weighing machine. 
     An embodiment, such as the trough design of  FIG. 2  (including floor  255  coupled to walls  256 ,  257 ) provides singulation (the ability to move product into the receptacle one product at the time or close thereto) on all weighments from 1-25 lbs with no adjustments necessary. 
     An embodiment includes a food grade plastic pusher plate mounted to each end of an air cylinder which rides on sealed maintenance free cam follower bearings for a long life with little to no friction. 
     An embodiment includes a trough mounted from the back (near a fully retracted pusher plate), away from product touch areas (near where an operator may be working near the output end portion of the trough) so no screws, bolts or fasteners exist to come loose and fall out (possibly getting into the bags) and no mounting holes or screw heads exist (where contamination can develop). 
     An embodiment is configured so that when fully assembled, even with weighment holding collector and electrical control cabinet, the embodiment still fits into a standard width semi trailer with no disassembly of the machinery necessary. 
     An embodiment includes a front shield (element  491  of  FIG. 4 ) on each trough that is constructed of clear food-grade polycarbonate for observation. The shield is adjustable to provide settings for bigger or smaller bag sizes (adjusting the position using a pinch knob such as knob  760 ). 
     In an embodiment the bag clamping mechanism on each of the 8 heads consists of left and right inner clamps ( 443 ,  444 ) which may be available in, for example, 3″, 5″ and 7″ widths for different bag sizes from ranging from 1-25 lbs. 
     In an embodiment the inner ( 443 ,  444 ) and outer ( 440 ,  441 ) clamps on each side of a head (left and right sides) are tied together with a connecting rod  342 . The outer clamps are adjustable (“in” for narrow bags or “out” for wider bags). The inner and outer clamps are driven together or apart by a single air cylinder  347  per head. When the inner clamps are closed together to allow for an operator to hang a bag, the outer clamps are driven apart giving the operator access to the inner clamps without the outer clamps impeding the bag hanging process. 
     When the operator hangs a bag on the closed clamps the operator contacts rod  450  (which is attached to an air switch) with the back of his or her hand. This supplies a burst of air to a valve and switch that drives the air clamping cylinder  347 . This opens the inner clamps and closes the outer clamps pinching the bag in place. 
     As mentioned above, an embodiment allows small and large weighments (e.g., 1-25 lbs) and small to large products (e.g., key limes, small potatoes, oranges, onions, and grapefruit). The trough is designed so that there is no funnel effect where product will jam while entering the bag. The embodiment (e.g.,  FIG. 2 ) requires no additional pieces to be added when running small bags, small weighments, and small products. In an embodiment the trough is 24.5″ long, 12″ wide, and 11″ deep allowing more than enough room for up to 25 lb weighments or more. 
     In an embodiment the shape of the trough is such that the bottom center (floor  255 ) may use a small 1 lb bag on up to 25 lb bags and more. The sidewall/floor coupling angle encourages singulation of product by directing product to the center of the bag. The pusher plate helps promote product being delivered to the bag slowly as the carousel rotates (unlike traditional carousel baggers that deliver the entire weighment of product to the bag at once). 
     In an embodiment, the width of the trough meets the width of the bag (e.g., see  FIG. 2 ) so no funneling of product is necessary. The product is pushed forward along the trough into the bag. 
     In an embodiment product, such as 10 lbs of oranges, proceeds with natural singulation to the center of the trough dictated by the shape of the trough. The bag clamps are wider than the base of the trough so product is pushed from, for example, a 4″ opening (e.g., dimension  258 ) in the base of the trough to a 6″ opening where the bag is clamped ensuring that all product falls quickly into the bag without jamming (because the available bag opening is equal to or larger than the base of the trough in an embodiment). 
     In an embodiment the pusher plate is connected to and driven by an air cylinder. A conventional air cylinder consists of a body and a ram that extends out from or retracts into the air cylinder body. However, an embodiment includes an air cylinder that also uses a rod and a body but the rod extends out of each end of the body of the cylinder (see  FIG. 1 ). In an embodiment, when the rod is extended out from the air cylinder on one end the rod sticks out 25″ on one side of the cylinder and 1½″ out the other side of the cylinder. When used in conjunction with 8 conveyor troughs system  100  uses only 4 air cylinders to do the work of 8 conventional air cylinders. The two heads opposite each other share an air cylinder  131  that is connected to the pusher plates  105 ,  106  in each of the opposing troughs. In  FIG. 1  heads  1  &amp;  5 ,  2  &amp;  6 ,  3  &amp;  7 , and  4  &amp;  8  each share air cylinders. When head # 1  (trough  120 ) has the pusher plate fully retracted the opposite head # 5  (trough  121 ) is serviced by the same air cylinder  131  and at this point has the pusher plate fully extended having pushed the entire product into the bag. 
     Thus, various embodiments concern a continuously rotating machine element consisting of 8 bag clamped filling troughs designed to slowly move a weighment of product from the filling trough to the pre-hung bags as the machine rotates. 
     While conventional carousel baggers are designed to work with weighments from 3-20 lbs, any smaller weighment and the opening to the bag becomes a funnel shaped restriction resulting in damaged product or jamming of product that does not get into the bag (i.e., the output of the conventional trough is wider than the input to the bag). Flat floor  255  is configured such that the bag width of a 1 lb bag is accommodated with outwardly angled sides above the floor (and maximum width  258  may vary in other embodiments to go even smaller for smaller bags and vice versa for larger bags). In an embodiment each trough has a height of 11″, length of 26″, and provides enough volume to hold a 25 lb weighment (although in other embodiments a single system may include differently sized troughs to accommodate different articles or size of articles). The width of troughs in floor system  100  works with 1 lb bags with no restrictions and further accommodates up to 25 lb bags with a naturally occurring singulation of product based on the trough design (resulting in no jamming of any standard sized produce at weighments from 1-25 lbs and beyond). 
     An embodiment includes a method of filling pre-made bags or boxes with weighments of product. While food products have been discussed above embodiments are not limited to the same and may accommodate any articles that need loading. 
     Embodiments include troughs with a shape that helps prevent product blockage, a bag clamping mechanism that moves both the outer and inner bag clamps as a unit for maximum bag clamping, and the use of 4 air cylinders each with a pusher rod extending through the body of the air cylinder to each move a pusher plate in 8 filling troughs (i.e., a non 1:1 ratio between actuator and pusher plate). 
     Embodiments may include programming to operate systems such as system  100  (e.g., to advance the pusher plate to distribute the articles over the course of an arched path). Embodiments may be implemented in code and may be stored on a non-transitory storage medium having stored thereon instructions which can be used to program a system to perform the instructions. The storage medium may include, but is not limited to, any type of disk including floppy disks, optical disks, solid state drives (SSDs), compact disk read-only memories (CD-ROMs), compact disk rewritables (CD-RWs), and magneto-optical disks, semiconductor devices such as read-only memories (ROMs), random access memories (RAMs) such as dynamic random access memories (DRAMs), static random access memories (SRAMs), erasable programmable read-only memories (EPROMs), flash memories, electrically erasable programmable read-only memories (EEPROMs), magnetic or optical cards, or any other type of media suitable for storing electronic instructions. 
     Embodiments may be implemented in many different system types. Referring now to  FIG. 8 , shown is a block diagram of a system in accordance with an embodiment of the present invention. System  500  may be used to implement code/logic for operating system  100  (e.g., to advance the pusher plate to distribute the articles over the course of an arched path). Multiprocessor system  500  is a point-to-point interconnect system, and includes a first processor  570  and a second processor  580  coupled via a point-to-point interconnect  551 . Each of processors  570  and  580  may be multicore processors. The term “processor” may refer to any device or portion of a device that processes electronic data from registers and/or memory to transform that electronic data into other electronic data that may be stored in registers and/or memory. First processor  570  may include a memory controller hub (MCH) and point-to-point (P-P) interfaces. Similarly, second processor  580  may include a MCH and P-P interfaces. The MCHs may couple the processors to respective memories, namely memory  532  and memory  534 , which may be portions of main memory (e.g., a dynamic random access memory (DRAM)) locally attached to the respective processors. First processor  570  and second processor  580  may be coupled to a chipset  590  via P-P interconnects, respectively. Chipset  590  may include P-P interfaces.
