Definitions

  • the present invention relates to a packaging system that comprises two intermittent rotation-type bag filling and packaging apparatuses disposed in close proximity to each other.
  • An intermittent rotation-type bag filling and packaging apparatus is an apparatus that holds two lateral edges of each one of bags using a pair of left and right grippers and intermittently conveys the bags along a circular conveying path in equiangular steps while successively performing packaging operations to each bag during the conveyance such as opening the mouth of the bag, filling the bag with the material to be packaged, sealing the mouth of the bag, and unloading a product bag (bag on which the packaging operations have been completed).
  • the intermittent rotation-type bag filling and packaging apparatus includes a rotary table which, for each of these packaging operations, has multiple pairs of right and left grippers disposed around the periphery of the table.
  • the rotary table intermittently rotates, thereby causing the grippers to intermittently travel along circular travel paths in equiangular steps.
  • Other various packaging devices of the intermittent rotation-type bag filling and packaging apparatus include an empty bag supplying device that supplies empty bags to the grippers, a mouth-opening device that opens the mouths of the bags held by the grippers, a packaged material filling device that fills the bags held by the grippers with material to be packaged, a mouth-sealing device that seals the mouths of the bags held by the grippers, a product bag-unloading device that receives sealed product bags from the grippers and removes them from the conveying path.
  • These packaging devices are disposed in the vicinity of the respective stop positions in the travel path of the grippers and successively perform the above-mentioned packaging operations.
  • the intermittent rotation-type bag filling and packaging apparatuses generally comprises two types.
  • One type of intermittent rotation-type bag filling and packaging apparatus uses a pair of right and left grippers to hold bags in an upright (vertical) orientation so that the bag mouth faces upward (see Japanese Patent Application Laid-Open (Kokai) No. 2007-126208), and the other type uses a pair of right and left grippers that hold bags in a horizontal attitude (see Japanese Patent Application Laid-Open (Kokai) No. H6-144403).
  • the packaging operations are carried out to grippers that have come to a stop in the travel path or to bags that have come to a stop in the conveying path. Accordingly, packaging can be performed in a reliable and stable manner.
  • Bags are conveyed along a circular conveying path in generally the bag width direction. Accordingly, bag swing motions are less likely to occurs during bag conveying process in comparison with intermittently conveying-type bag filling and packaging apparatuses, in which bags are conveyed along a rectilinear conveying path in the thickness direction of the bags (see Japanese Patent Application Laid-Open (Kokai) No. 3-29650).
  • various problems due to the swinging of the bags such as, for example, downward slippage of heavy bags filled with the material to be packaged from the initial holding position of the grippers, the spilling of liquid substances that the bags are filled with, and adhesion of liquid substances to the portion to be sealed on the inner surface of the mouth, are less likely to occur.
  • Each packaging device can be disposed around the periphery of the rotary tables, namely, in the vicinity of the peripheral edges of the packaging apparatus. Accordingly, it is easy to perform part replacements, to make adjustments, etc. associated with changes in the type of the product to be handled. For this reason, intermittent rotation-type bag filling and packaging apparatuses are highly versatile and easy to maintain and clean. By contrast, in intermittently conveying-type bag filling and packaging apparatuses (see Japanese Patent Application Laid-Open (Kokai) No. 3-29650), the packaging devices are disposed in the vicinity of the central portion of the packaging apparatus; accordingly, part replacements, adjustments, maintenance, cleaning, and the like are relatively difficult.
  • the bag conveying path is circular. Accordingly, intermittent rotation-type bag filling and packaging apparatuses can effectively utilize substantially all of the conveying path for packaging and can provide space-saving and effective packaging operations. To the contrary, in intermittently conveying-type bag filling and packaging apparatuses (see Japanese Patent Application Laid-Open (Kokai) No. 3-29650), no packaging operations can be performed in the return portion of the chain conveyor.
  • intermittent rotation-type bag filling and packaging apparatuses possess the above-described advantages, they have structural limitations on their speed of operation, and their processing power is inferior to that of continuous transport-type bag filling and packaging apparatuses.
  • intermittent rotation-type bag filling and packaging apparatuses convey bags in the bag width direction, they have a longer single conveying distance (conveying distance between the intermittent stop positions) than intermittently conveying-type bag filling and packaging apparatuses, which convey bags in the thickness direction (see Japanese Patent Application Laid-Open (Kokai) No. 3-29650), and their processing power is inferior to that of intermittently conveying-type bag filling and packaging apparatuses.
  • multiple-bag intermittent rotation-type bag filling and packaging apparatuses have been proposed, in which multiple empty bags are simultaneously fed to multiple pairs of grippers on rotary tables, and, while the multiple bags are being conveyed, the same packaging operations are simultaneously performed on the multiple bags in each stop position.
  • the diameter of the rotary tables i.e., the diameter of the bag conveying path
  • the conveying distance between the intermittent stop positions is also longer.
  • the speed of rotation of the rotary tables is the same, the speed of bag conveyance and their acceleration/deceleration are high in comparison with ordinary single-bag intermittent rotation-type bag filling and packaging apparatuses. Accordingly, the bag swinging associated with intermittent transport increases, and there is a risk that various problems may arise due to such swinging (see (3) above).
  • each intermittent rotation-type bag filling and packaging apparatus needs to be provided with its own drive source, and moreover if product bags from individual intermittent rotation-type bag filling and packaging apparatuses are merged into a single stream, it is necessary to install dedicated equipment to deal with it, which makes the product bag carry-out line more complicated.
  • the present invention is devised in view of the current state of the art in the field of intermittent rotation-type bag filling and packaging apparatuses, and it is an object of the invention to provide a packaging system that accomplishes improvements in processing capacity with a pair of intermittent rotation-type bag filling and packaging apparatuses and further contributes installation space reduction and power savings in comparison with the existing art while at the same time simplifies product bag carry-out lines for such two packaging apparatuses.
  • the product bag unloading devices can be disposed adjacent each other in the most mutually proximate stop positions among stop positions of the grippers disposed on both rotary tables, and the empty bag supplying devices are disposed adjacent each other in mutually proximate stop positions that follow, in terms of the direction of rotation of the two rotary tables, the most mutually proximate stop positions.
  • the empty bag supplying devices can be disposed adjacent each other in the most mutually proximate stop positions among stop positions of the grippers disposed on both rotary tables, and the product bag unloading devices are disposed adjacent each other in mutually proximate stop positions that precede, in terms of the direction of rotation of the two rotary tables, the most mutually proximate stop positions.
  • the same intermittent indexing mode means that for both rotary tables, the duration of a single cycle of motion and stationary state, the distribution of travel time and stationary time during a single cycle, and the indexing angles are identical during the intermittent indexing motion of the rotary tables.
  • the timing of stop and rotation of the intermittent rotation of the two rotary tables is set to be substantially inverse to each other.
  • the two intermittent rotation-type bag filling and packaging apparatuses have a common carry-out conveyor installed to discharge product bags supplied by each product bag unloading device in an alternating manner.
  • the empty bag supplying devices, mouth-opening devices, packaged material filling devices, mouth-sealing devices, and product bag unloading devices are disposed in linearly symmetrical positions so that a line perpendicular to the line that connects the rotary shafts of the two rotary tables serves as an axis of symmetry.
  • the grippers disposed on the rotary tables are of the duplex type, in which two pairs constitute a single set, and the holding surfaces of the two pairs of grippers of the same set used when holding a bag are disposed substantially in the same plane.
  • the two rotary tables are rotated in opposite directions, and two empty bag supplying devices and two product bag unloading devices are disposed adjacent each other on a common base between the two rotary tables.
  • the spacing between the two rotary tables can be narrower, and installation space reduction can be achieved for the entire packaging system.
  • the product bags unloaded from the two intermittent rotation-type bag filling and packaging apparatuses are collected in a single location. Accordingly, the product bag transport line used to transport the product bags for post-processing is shared by the two intermittent rotation-type bag filling and packaging apparatuses and thus can be simplified, which also leads to installation space reduction.

  • FIG. 2 is a top view illustrating another example of a packaging system according to the present invention.
  • FIG. 3 is a top view illustrating yet another example of a packaging system according to the present invention.

  • the intermittent rotation-type bag filling and packaging apparatuses 2 , 3 include rotary tables 5 , 6 , respectively, that have multiple pairs (8 ⁇ 2 sets) of right and left grippers 4 disposed around their periphery.
  • the rotary tables 5 , 6 intermittently rotate, thereby causing the grippers 4 to intermittently travel along the circular travel paths in equiangular steps.
  • the diameters of the travel paths of the grippers 4 of the rotary tables 5 , 6 are set to be the same.
  • the intermittent rotation-type bag filling and packaging apparatuses 2 , 3 make a duplex intermittent rotation-type bag filling and packaging apparatus (see Japanese Patent Application Laid-Open (Kokai) No. 2005-67644), in which two empty bags are simultaneously supplied to two pairs of grippers of the rotary tables 5 , 6 and various packaging operations are simultaneously performed on the supplied two bags in each stop position while the two bags are being conveyed along the predetermined conveying paths.
  • a drive motor, etc. (not shown), which serves as a common drive source to rotate the rotary tables 5 , 6 , is provided in the base 1 .
  • the drive force of the drive motor is transmitted to the index devices (not shown) of the rotary tables 5 , 6 through reduction gears (not shown) and is then transmitted to the rotary tables 5 , 6 .
  • the transmission of the drive force to the index devices of the rotary tables 5 , 6 can be individually enabled or blocked using, e.g., a clutch.
  • the intermittent indexing modes of the rotary tables 5 , 6 are set using the indexing devices such that they are identical.
  • the rotary tables 5 , 6 are intermittently rotated in mutually opposite directions (the rotary table 5 of the intermittent rotation-type bag filling and packaging apparatus 2 is rotated counterclockwise while the rotary table 6 of the intermittent rotation-type bag filling and packaging apparatus 3 is rotated clockwise) and, at the same time, the timing of moving (rotation) and stopping is set to be substantially inverse to each other.
  • the rotary table 5 is at a stop while the rotary table 6 is moving (rotating).
  • the timing of moving and stopping of the rotary tables 5 , 6 is set to be substantially inverse to each other (the timing of moving and stopping is shifted by a half-cycle), the load applied to the drive source is evened out, and it is possible to render the drive source more compact and improve its durability without reducing the processing power of the packaging system.
  • the rotary tables 5 , 6 stop eight times at equiangular intervals, respectively.
  • the position of closest proximity between the travel path of the grippers 4 of the rotary table 5 and the travel path of the grippers 4 of the rotary table 6 is selected as one of the stop positions (stop position H of the table 5 and stop position h of the table 6 ) of the grippers 4 in the travel path, and seven other stop positions (A-G of the table 5 and a-g of the table 6 ) are set at angular intervals of 45° from the stop positions H, h along the travel paths.
  • Product bag unloading devices 8 , 9 which removes the product bags 7 A out of the conveying path, are disposed so as to be adjacent each other on the base 1 in the vicinity of the most proximate stop positions H, h among the stop positions A-H and stop positions a-h, respectively.

  • the drive source that intermittently rotates the rotary tables 5 , 6 is also the drive source that actuates the various packaging devices that are described above and provided around the tables 5 , 6 .
  • the transmission of drive force to the various packaging devices which is done in the same manner as to the rotary tables 5 , 6 , can be enabled or blocked using the clutch.

  • These conveyor magazine-type empty bag supplying device 24 and product bag carry-out conveyor 25 are shared by the intermittent rotation-type bag filling and packaging apparatuses 2 , 3 , and therefore only one conveyor magazine-type empty bag supplying device 24 and one product bag carry-out conveyor 25 is sufficient for both filling and packaging apparatuses.
  • the conveyor magazine-type empty bag supplying device 24 has quadruplex conveyors 24 a - 24 d aligned longitudinally in parallel to each other.
