FIG. 1 , the system comprises a batching supply (R) and stations automatically and sequentially building a pallet supporting two bulk bags stacked one on top of the other, as controlled by a programmable controller (PLC) (not shown). - Best seen in
FIG. 8 , the batching supply (R) receives the product to be bagged and feeds a first and a second filling stations, namelystations conveyor -
Station 1, which will be discussed hereinbelow in relation toFIG. 2 , is a pallet feeder, providing a pallet under a first empty bag.Station 2 is a first filling station, for filling a first bag on the pallet (seeFIG. 3 ).Station 3 prepares the first bag (i.e. bottom bag of the stacking) to receive a second bag (i.e. top one bag of the stacking) (seeFIG. 5 ) to.Station 4 is a second filling station, for feeding the second (top) bag (FIG. 6 ). Finally,station 5 is a bag straightener station, where the stacked bags are straightened and compressed on the pallet (FIG. 7 ). - The batching supply (R) is supported by a
structure 92 bolted to theframe 31 of the station 3 (seeFIGS. 5 and 8 a). - The batching supply (R) is fed with the product the be bagged, for example by a conveyor dumping in a small
bidirectional conveyor 90 to select in which side of thedivider plate 91 to dump the product, as controlled by the PLC (seeFIG. 8 b). - The batching supply (R) is used to pre calibrate the amount of product in the bags. The system as illustrated herein is able to make two different bag volumes: 55 and 75 cu foot bags. In this example, the batching supply (R) is divided into two by the divider plate 91 (
FIG. 8 b) located between theconveyors filling stations Capacitive sensors FIGS. 8 b and 8 d) staked one above the other on each side of the batching supply (R), are used to monitor the amount of product conveyed to the respective bags. For example,bottom sensors mid ones top ones gates conveyors station FIG. 11 ). -
FIG. 2 show details ofstation 1.Station 1 feeds thefirst filling station 2 with a pallet, one at the time. -
Station 1 is in automatic mode as programmed by the PLC. The operator has access to an operator panel comprising different windows, for selection of a specific window (FIG. 9 a), automatic screen (FIG. 9 b), manual screen bidirectional motion (FIG. 9 c), manual screen unidirectional motion (FIG. 9 d), timers screen (FIG. 9 e), log of input/output of PLC (FIG. 9 f), alarms (FIG. 9 g) and help screen (FIG. 9 h). -
Station 1 comprises aframe 10 supporting a pallet pusher best seen inFIGS. 2 b and 2 c. The PLC controls lifterarms 12 of the pallet pusher ofstation 1, so that thelifter arms 12 move down to leave a bundle of pallets onrails 19. Thelifter arms 12 open and elevate a first pallet (not shown) from the bundle before they close again on the bundle. A third step is to lift back the pallet bundle to give room to the first pallet to move forward. When the pallet pusher receives instruction from the PLC to move forward the pallet, achain 18 is activated (seeFIG. 2 d), by an electric motor with a gear box to decrease the chain speed to the same speed as theroller conveyor 22 ofstation 2. Agusset 13 welded on thechain 18 moves the pallet forward to push it towardsstation 2 to afront stop sensor 14 of the pallet pusher (seeFIGS. 2 b, 2 d). When the pallet is seen instation 1, the PLC gives a reverse command to the pallet pusher and the pallet pusher stops at aback sensor 15. After that step,station 1 awaits for another order for a new pallet, in a waiting mode. - The
frame 10 of the pallet feeder is a totally enclosed pallet magazine. It is enclosed by twodoors 101 at the back (seeFIG. 2 a), which also keep the pallet bundle straight. If an operator needs to add a pallet, the operator has to push a button to let know the PLC. Then, thelifter arms 12 move down to leave the bundle on therails 19. Thelifter arms 12 open to give room to the operator to place the pallet bundle in it. The operator is then able to open adoor latch 103 and open thedoors 101. Thedoor latch 103 is provided with a sensor 102 (seeFIG. 2 e) to let know the PLC to stop the operation of thatstation 1 for safety. -
Station 2, in automatic mode, puts a pallet on a pallet conveyor 22 (seeFIG. 3 a). The operator, working on a catwalk, takes a bag on a bag platform and attaches it onhooks FIG. 3 b). As illustrated inFIG. 10 a, the bags are made with anopen mouth 102 to fill the bags and comprise fourstraps 101, one on each top corner of the bags. The operator pushes eachstrap 101 into one of twofront hooks 28 and tworear hooks 25 to hold the bag instation 2. -
FIG. 4 shows details of the hooks holding the bags. Ahook head 282 is bolted on a frame, such as a piece of steelflat bar 280. Thehook head 282 is swiveled on one axis of about 100 degrees rotation. Anair cylinder 281 is fixed on a first end thereof on theframe 280 and on a rod end thereof on thehook head 282. Thus, when theair cylinder 281 is retracted, thehook head 282 is opened and frees the straps of the bag. When theair cylinder 281 is fully extended, thehook head 282 is closed, thereby securing the straps of the bag. A flexible piece ofUHMW 283 may be provided for closing the opening of thehook head 282, so that the strap needs only by pushed on thepiece 283 to be made to enter thehook head 282 without having to open thehook head 282. - The front hooks 28 are fixed to the lifting
mouth 26 of station 2 (seeFIG. 3 b). In contrast, the back hooks 25 are movable, by amover 29 actuated by anair cylinder 24, from a front position to help the operator to attach the straps in the hooks, to a back position to lift the bags straight and not choke the discharge of product in the bag. - When the bag is installed on the
hooks mouth 26 ofstation 2 and installs the bag thereon. Themouth 26 comprises air clamps 27 (seeFIG. 3 b) to hold the bag mouth in place. When the bag is in place on thefeeder mouth 26, the operator presses abutton 1A on the control interface (FIG. 11 ), thereby instructing the PLC to close theclamps 27 to hold the bag mouth, thus preventing the product from leaking out of the bag and the dust from blowing out from the bag. At this time, when the button is pushed, the supply (FIG. 8 a) feeds the bag with aconveyor 70 during an amount of time controlled by the PLC according the value the operator previously entered in the control panel (seeFIG. 9 e timer screen). Between the shoots ofconveyor 70 and thefiller mouth 26, a flexible tube (not shown) may be provided to flow directly in the bag and prevent the leaks. - During the filling time, after preselected timer (entered in the machine control panel by the operator), the lifting mouth filler 26 (see
FIG. 3 b) rises and gets down automatically, under action of the up/down cylinder 21 (best seen inFIG. 3 a) to shake the bag and the product in it to place the product to make sure the bag is as stable as possible. Guidingplate 23 prevents the bag from bulging, so that the bag takes an overall square or rectangular shape footprint corresponding to the pallet. - At the end of filling time, the
clamps 27 open to let the operator attach the mouth with the rope of the bag, to make sure no contaminants enter the bag during transport or before his utilization. - When the bag is thus sealed, the operator pushes a button 1 b (see
FIG. 11 : bag tied ready to exit from station 1) to drop the bag on the pallet (not shown) sitting on theconveyor 22. When the next station,station 3, comes empty, i.e. without any pallet on itsconveyor 32, the pallet with the first bag thereon is moved forward to station 3 (FIG. 5 ). When thestation 2 is emptied, the operator is able to put another bag on the filler and start back the filling of a bottom bag again. - At
station 3, a positioning hole is made on the top surface of the bottom bag before the top bag is put sitting thereon. A pallet with a filled first bag as described hereinabove comes from station 2 (FIG. 3 ). Theconveyors 22 ofstation station 3 run until a sensor indicates the pallet is centered onstation 3. As shown inFIG. 5 , guidingplates 33 are provided to square the bag again to make sure the load is not overflowing the pallet. When the pallet is stopped and centered, acompression cylinder 34 moves a plate down to form a concave area in the middle of the bag, intended to accommodate the bottom of the second filled bag so that the second filled bag, when stacked on top of the first filled bag, sits on top of the first filled bag in a stabilized equilibrium. The plate goes down until hitting asensor sensor 35. That timer is in the panel view and it can be changed by the operator. When the next station,station 4, comes empty, i.e. without any pallet on its conveyor 42 (seeFIG. 6 ), the pallet is moves forward tostation 4. Theconveyors station 3 tostation 4 until a sensor indicates arrival atstation 4, then theconveyors -
Station 4, described in relation toFIG. 6 , is provided to fill a second bag, without a pallet under it. -
Station 4, in automatic mode, is ready, waiting the operator to install an empty bag onhooks straps 101 and put them on thehooks mouth 46 ofstation 4, thereby hanging the second bag ready for filling up. Then the operator pushes a button on the interface (see button bag ready to fill, seeFIG. 11 ), thereby triggering the supply (FIG. 8 ) to start and fill the bag with theconveyor 80. Between the shoots ofconveyor 80 and thefiller mouth 46 of station 4 (seeFIG. 6 ), a flexible tube (not shown) may be provided to flow directly in the bag and prevent leaks. Atstation 4, no pallet is on theconveyor 42 because the pallet of thestation 3 is coming later in the process. -
Hooks FIG. 3 and best seen inFIG. 4 , are used to secure the straps of the second bag. Front hooks 48 are fixed to the liftingmouth 46 ofunit 4. Back hooks 45 are movable, using backhook mover 49 actuated by anair cylinder 44, between a front position to help the operator to attach the straps in the hooks and a back position to lift the bag straight and not choke the discharge of product in the bag. When the bag is installed on thehooks mouth 46 to install the bag on the fillingmouth 46. Themouth 46 comprises air clamps 47 on each side. These clamps 47 are closed by the operator when he has finish to place the bag mouth on thefeeder mouth 46, to hold the bag mouth in place, prevent the product from leaking out and the dust from blowing out from the bag, when the operator pushes on the button close clamps of the operator interface (Button 2A, seeFIG. 11 ). When the bag is in place at the station 4 (FIG. 5 ), the operator pushes a button to notify the PLC that the second bag is ready to fill. Then, the batching supply (R) (FIG. 8 a) feeds the second bag with theconveyor 80 during an amount of time controlled by the PLC according to a value previously entered by the operator in the control panel. Between the shoots ofconveyor 80 and thefiller mouth 46, have a flexible tube (not shown) may be provided to flow directly in the bag and prevent the leaks. - During the filling time, after a preselected timer (entered in the machine control panel by the operator), the
lifter frame 41 of themouth filler 46 rises and gets down automatically to shake the second bag and the product therein to distribute the product in the bag and ensure stability of the bag. Guidingplates 43 are provided to hold the bag into a generally square shape footprint corresponding to the pallet. - At the end of filling time, clamps 47 open to let the operator attach the mouth of the bag with a rope, to prevent ingress of contaminants during transportation or before utilization.
- When the bag is thus sealed, the operator pushes a button 2 b on the operator interface (
FIG. 11 : Bag tied, elevator ready to go up), thereby activating thelifter frame 41 to go up and pass in front of a sensor indicating a stop position. At that time, the PLC is instructed that it is safe to move the pallet from theconveyor 32 of station 3 (FIG. 5 ) tostation 4 on theconveyor 42, beneath the second full bag, lifted in a waiting position by thelifter frame 41. The pallet with the first bag thereon is then stopped with its load centered onconveyor 42 atstation 4 beneath the second full bag. The PLC orders dropping of the second bag on the pallet sitting on theconveyor 42 and opening of the hooks to free the second bag on top of the first bag, thereby forming a double staked pallet, as shown inFIG. 10 b. Thefirst bag 103, filled atstation 2, is topped by thesecond bag 104, filled atstation 4. - When the next station, i.e.
station 5 shown inFIG. 7 , comes empty, i.e. without any pallet on itsconveyor 42, the pallet with the double staked pallet is moved tostation 5. Whenstation 4 is emptied, the operator is able to put another bag on the filler and start back the process again for filling next second bag for another double staked bag. - Station 5 (see
FIG. 7 ) is used to straighten and square the bags on the pallet, so that the double bag is typically no more than 42″×50″ and preferably of the same size as the pallet (typically 40″×48″). Four walls are made to enclose the bags on the pallet, and after the walls are in place, a compression plate compresses the bags for stability. -
Station 5, like the rest of the system, is controlled by the PLC. At a waiting position, the walls ofstation 5 are positioned at an opened position to leave maximum room for the pallet coming fromstation 4 to enterstation 5 conveyed by theconveyor 52. When a pallet is ready on theconveyor 42 of the station 4 (FIG. 6 ), the PLC checks that theconveyor 52 ofstation 5 can move the pallet forward. If there is no pallet on theconveyor 52 ofstation 5, theconveyors conveyor 52 ofstation 5, theconveyors - At that time, the walls of
unit 5 are put into action, powered by hydraulic power. The walls are moved by step by step displacement toward the pallet. Astructure 55 ofmobile walls conveyor 52 until a linear movingframe 56 passes in front of a sensor and stops it (FIG. 7 a). Thestructure 55 is bolted on theframe 56 which is actuated by a hydraulic cylinder. As best seen inFIG. 7 b, the linear displacement of the frame 56 (seeFIG. 7 a) is controlled by guidingrails 561 and ahydraulic cylinder 562, so that rolling bearing wheels of the moving walls are turning in the guidingrails 561 to make sure the displacement is straight and the walls are strong to hold the load. - In a second time, two opposite moving
walls FIG. 7 f) and ahydraulic cylinder 582. Using a pivot allows synchronizing the walls together to make sure the load is not pushed or moved more on one side than on the other side, and thus that the load is equally supported and stable. - As best seen in
FIG. 7 f, thecylinder 582 extends or retracts to rotate thepivot 581, which in turn, via timingbars 585, pulls or pushes timing bars 585 to move (linearly) in/out twoopposite side walls linear guide 587. Thepivot 581 with the timing bars 585 make the twowalls walls walls - When the three
walls wall 532 opposite thewall 588, supported by astructure 53 bolted on themain structure frame 51 ofstation 5 as shown inFIG. 7 a, is activated. Thiswall 532 is moved by two strong cylinders 533 (FIG. 7 e). Thesecylinders 533 are pinned in somehigh adjustment 531 allowing adjusting the level of the cylinders in relation to the weight distribution in the stacked bags. Thewall 532 is pushed towards the double stack bags until triggering a stop a sensor, at which point the four walls form a square enclosure around the bags. - In a final step, compression is achieved by a top plate 542 (
FIG. 7 d), in a similar way as discussed in relation to station 3 (FIG. 5 ).FIG. 7 d shows details of the topcylinder plate structure 54 used to compress the bags in the enclosure formed by the four walls as described hereinabove. Thetop plate structure 54 is bolted on theframe 51 ofstation 5 and supports a compaction cylinder 543 actuating thecompaction plate 542 through acompaction shaft 544 to give compaction strength to theplate 542.Compaction bushing 545 guides theshaft 544 to ensure theshaft 544 have a straight displacement and thecompaction plate 542 has no bending or unbalanced pushing action on the bags. - With the four
walls compaction plate 542 is moved downward to compress the bags, until triggering a bottom sensor, when theplate 542 is stopped for a time, controlled in the PLC by the panel view. The operator can change that timer manually in the panel view to adjust the time theplate 542 remains on top of the bags. - When that timer is done, the four
walls plate 542 are withdrawn away from the bags, leaving compressed, straight bags on the pallet. The pallet with the bags is then moved onconveyor 52 to a wrapping machine. - Although the present invention has been described hereinabove by way of embodiments thereof, it may be modified, without departing from the nature and teachings of the subject invention as described herein.
