Definitions

  • the present invention relates to automatic machinery for bag emptying. More particularly, the present invention relates to an automatic gripping, splitting and emptying bags.
  • raw material is delivered in medium to large sized bags.
  • the bags are arranged on pallets.
  • discharging the bags' content is achieved by manual unloading and slitting the bags employing a knife and transferring the material to a receiver such as a funnel. Since the bags are relatively heavy, emptying the material into the processing machine by the worker that lifts the bags one after the other constitute a "bottle neck" in the progress of the processing.
  • raw material which can be very expensive, is being lost throughout the process of emptying the bags into a receiver since a worker has to carry the sliced bag and shake it over above an opening of a receiver or a funnel.
  • a splitter system does not avoid the need for manual emptying which is costly both in labor and in the loss of material.
  • a bag full of raw material is inserted into the machine that shreds the bag so as to allow all the raw material to be dispensed into the processing apparatus. Due to the form of shredding, small pieces of shredded bag may enter the processing apparatus along with the raw material.
  • the process does not eliminate the need of the worker that places the bags in the machine. Therefore an apparatus that will quickly, mechanically slit the bags and empty them into a receiver of the processing apparatus is beneficial.
  • an apparatus for gripping, lifting and emptying layered bags is provided.
  • the apparatus consists of the following subsystems: a gripping unit including a gripper, a bag slitting and emptying device, a controller and an optional container for debris of bags.
  • the gripper is capable of gripping one or more bags ordered or heaped in disorder.
  • the gripper consists of a plurality of gripping elements arranged in two arrays such that a bag is gripped by a number of gripping elements disregarding the bags' arrangement in a layer.
  • the gripper is optionally provided with weighing means by which the weight of gripped bags is measured.
  • the gripper is incorporated in a gripping unit which also lifts the gripped bags and carries them to the bag slitting and emptying device.
  • the bag slitting and emptying device simultaneously slits and empties the bags by means of a plurality of rotary blades aligned with rods. A cyclic displacement of the rods relative to the slitted bags discharges leftovers of the contents of the bags.
  • a controller controls each sub-system and orchestrates the entire apparatus, such that the level of an operator intervention is substantially low.
  • Fig. 1 is a schematic description of the main subsystems of an apparatus for emptying bags of the invention wherein the gripping unit is loaded;
  • Fig. 2A is a schematic description of an array of gripping elements pivotally connected to a suspension shaft
  • Fig. 2B is a schematic description of an array of gripping elements pivotally connected to a suspension shaft in a drawn position
  • Fig. 2C is a description of another array of gripping elements pivotally connected to a suspension shaft in a drawn position
  • Fig. 3A is a front side view of a section of a gripper having its PGEs withdrawn according to a preferred embodiment of the present invention
  • Fig. 3B is a front side view of a section of the same gripper shown in
  • FIG. 2A 1 with drawn PGEs Fig. 3C is a bottom view of a section of a gripper according to another preferred embodiment of the invention ;
  • Fig. 4 is a frontal view of a section of an apparatus for emptying bags, before starting a step of slitting bags, according to a preferred embodiment of the present invention.
  • Fig. 5 is an isometric view of a section of a slitting and emptying device according to a preferred embodiment of the present invention;

  • Fig. 7 is an isometric view of an apparatus for emptying bags in accordance with the present invention.
  • Fig. 8 is a side view of the apparatus for emptying bags implementing debris compression
  • Fig. 9 is an isometric view of a section o1 an apparatus for emptying bags, in which a lift is incorporated according to an embodiment of the present invention.
  • the present invention provides a novel apparatus for emptying bags as for example to discharge a raw material into a receiver of a processing system.
  • the apparatus of the present invention simultaneously grips and lifts a plurality of bags from an upper layer of stacked bags, slits the bags and discharges their contents.
  • the apparatus of the invention is an assembly of several subsystems, each performing a certain task in the overall process.
  • Fig. 1 describes schematically the main structural units of an apparatus for emptying bags of the invention and the functional relationships between them.
  • gripping unit 12 picks up one or more bags 14 from stack 16. The bags are brought to the emptying unit 18 for slitting and emptying. When emptying has finished, the gripping unit 12 disposes of the debris of the empty bags 14. The griping unit 12 resumes its position at stack 16 and picks again one or more bags.
  • the function of the gripping subsystem is therefore repetitive, moving cyclically between two extreme positions.
  • This unit includes a gripper, an actuator and an extendible arm.
  • the role of the actuator is to move the gripping unit between the two extreme positions as described above.
  • the gripper according to the invention employs pointed gripping elements (PGEs) such as hooks or stakes. One end of each gripping element is connected to an axis whereas the tipped end is free.
  • PGEs are grouped in two arrays in each of which each of the PGEs point in the same direction.
  • the PGEs of both arrays are movable between two extreme positions respectively. The extreme positions are a fully drawn position and a fully withdrawn position. All the PGEs of an array move in the same direction when changing from one extreme position to the other.
  • FIGs. 2A - 2C exemplary two PGEs of an array 40 are pivotally attached to a PGE suspension shaft 42.
  • PGEs 44 and 46 are inclined towards shaft 42.
  • PGE 44A In a drawn positioning, PGE 44 is designated 44A, and PGE 46 as PGE 46A, in which position the free, pointed tips are pointing substantially away from the shaft 42, more towards the bottom.
  • the drawing - withdrawing action is forced by one or more actuators (not shown) which actuate forcing shaft 48 to position 48A.
  • the forcing shaft 48 is moved in the direction of arrow 50.
  • the two exemplary PGEs are fully drawn, designated here as PGE 44A and PGE 46A.
  • Forcing shaft 48A is in a PGE drawing position.
  • These PGEs are generally rotatable around pivots 50 but may be locked in a specific position.
  • Fig. 2C a portion of the other array of PGEs is shown drawn, wherein all PGEs are pointing in an opposite direction that the PGEs in Fig. 2B point. Moving these PGEs to the fully drawn position is similarly effected by moving forcing shaft 49A in the direction of arrow 5OA.
  • the extendible arm lowers the gripper to the upper layer of bags. Then, the PGEs are drawn, forcing their tipped ends into the accessible bags .
  • PGEs of one array are drawn in one direction whereas the PGEs of the other array are drawn in an opposing direction as described above.
  • the spacing between the individual PGEs of an array and the spacing between two adjacent PGEs of different arrays are typically changeable and are a matter of consideration of the bags, size and order. Tyically it is required that the bags when gripped and lifted should not be torn by their own weight.
  • the number of PGEs pointing in one direction of an array does not necessarily equal to the number of PGEs pointing oppositely of the other array.
  • Gripper 60 includes a plurality of rotatable PGEs. As described above PGEs of two different arrays are rotatable between two positions. PGEs 62 belong to one array and PGEs 63 belong to the other array. PGEs 62 are pivotally attached to suspension shaft 64 by means of axles 65 whereas PGEs 63 are attached by means of axles 65A. In Fig. 3A PGEs are shown in a fully withdrawn position. PGEs of both arrays are moved into a fully drawn position by counterclockwise rotating PGEs 62 and rotating PGEs 63 clockwise.
  • PGEs of one array are interleaved with PGEs of the other array.
  • PGEs of each array are arranged in rows according to this preferred embodiment of the invention wherein rows of different arrays are interleaved.
  • the PGEs of both arrays are fully drawn out and PGEs of both arrays are in the fully drawn position such that tipped ends of PGEs of different arrays such as 62B and 63B, point one towards the other
  • the pneumatic actuator 66 is attached to a frame of the gripper perpendicular to the rows of PGEs of both arrays.
  • the rows of PGEs are arranged in pairs such that one pair member is of different array than the other pair member.
  • PGE 62B is the extreme PGE in a row perpendicular to the plane of the drawing
  • PGE 63B is the extreme PGE in another row perpendicular to the plane of the drawing. All PGEs of a row have a common axis of rotation.
  • a proper selection of spacing between the PGEs in a row as well as the spacing between the rows can insure that each of the bags in the upper layer of stacked bags is gripped by a number of PGEs of both arrays.
  • a bag is characterized by a certain length, width and depth. The depth is typically significantly smaller than its width which is in turn smaller than its length.
  • the spacing between two adjacent pairs of rows of different arrays is such that the distance between the tipped ends of adjacent PGEs of different rows such as opposing when PGEs are fully withidrawn, is smaller than the a typical depth of a bag; the spacing between two adjacent pairs of the same rows is smaller than a typical length of a bag; and the spacing between two adjacent PGEs in a row is smaller than a typical width of a bag.
  • a gripper is capable of gripping bags of an upper layer arranged in any direction relative to its lower face. Furthermore a layer of bags need not be leveled in order to be gripped and lifted. However when the bags are layed out in disorder, only a portion of the number of bags in the top layer may be gripped at a time.
  • the tipped end section of the PGE moves along a circular path as it draws/withdraws.
  • the tip section is arcuate conforming with their rotation along a circular path. Therefore the hole punched in a bag by a PGE, is kept to a minimal size and the bags are not torn excessively by the rotating hooks. This allows for a minimal loss in contents along the path from the stack to the emptying position.
  • the shafts 65 to which the PGEs are attached are optionally suspended from a weighing device, not shown, which is connected to frame 68 of the gripper. To accomplish weighing, a load cell or preferably four load cells are employed. The measured weights are optionally further reported to a computer system carrying out tasks of process control and or material and stock management.
  • gripper 60 when located above the stacked bags, finely adjusts its positioning above the stack of bags to conform with the position of the upper layer of the stack, to be able to grip as much of the layer as possible.
  • at least one sensor 70 is employed.
  • Other grasping mechanisms may also be employed instead of, or in addition to, the PGEs of the gripper as described herein above.
  • vacuum nipples mounted on the bottom of the gripper's frame.
  • Fig. 3C a bottom side view of a section of a gripper according to another preferred embodiment of the present invention is shown.
  • the PGEs are pegs such as 72, 74 and 76. All PGEs point in a general downward direction. However PGEs of different arrays are tilted aside in opposite directions. PGEs 72 which belong to one array of PGEs are attached to a horizontal shaft 78 forming a row whereas PGEs 74 which belong to the other array are attached to shaft 80 forming another row of PGEs. PGEs 76 which are attached to shaft 82 belong to same array as PGEs 72 as they point in the same direction. The numbers of PGEs of both arrays need not be equal and the number of rows need not be even.
  • the PGEs of both arrays are shown in a fully withdrawn position.
  • Shafts 78, 80 and 82 are linearly movable along the directions shown by the double arrows 84 and 86 correspondingly, between the fully drawn and fully withdrawn positions.
  • the gripper having its PGEs withdrawn is placed on top of an upper layer of bags.
  • all PGEs are forced into the fully drawn position by moving shafts suchi as 76, 78 and 80, in a general downward direction along the arrows 84 and 86 as shown in Fig. 3C.
  • the upper surfaces of bags of the upper layer are punched by the tipped ends of the PGEs being forced into the bags while moving to a fully drawn position.
  • the parameters are i. the tilting angles of the PGEs; ii. the number of PGEs in a row; iii. the spacing between PGEs in a row; iv. the spacing between adjacent rows in which its PGEs are tilted towards each other such as rows of PGEs 72 and 74, and v. the spacing between rows in which its PGEs are tilted away from each other such as rows of PGEs 74 and 76.
  • These parameters are determined with reference to the dimensions of a layer of bags and the dimensions of an individual bag, such that a bag is gripped by a number of PGEs of at least two different rows.
