Definitions

  • the present invention relates to an apparatus for feeding cartons to be filled with milk or the like to carton bottom forming mandrels by fitting the carton around the mandrel.
  • Such carton feeders conventionally comprise a guide for holding the carton in alignment with the mandrel outwardly thereof while rendering the carton free to move inward toward the mandrel or outward away therefrom, a slider reciprocatingly movable inward and outward along the guide, a carton pushing pawl pivotably mounted on the slider so as to be pivotally movable between a position of engagement with the carton as held by the guide and a nonengagement position, and means for pivotally moving the carton pushing pawl toward the engagement position when the slider moves inward and pivotally moving the pawl toward the nonengagement position when the slider moves outward.
  • the pivotally moving means comprises a drive device including a hydraulic cylinder attached to the slider, and a control device for operating the drive device as timed with the inward and outward movement of the slider.
  • the hydraulic cylinder is attached to the slider, so that the reciprocatingly movable portion including the slider has a great weight, which results in a great load for driving the slider.
  • the drive device and control device for pivotally moving the carton pushing pawl are complex in construction.
  • the main object of the present invention is to overcome the above problems and provide a carton feeder comprising a slider of reduced weight, and a drive device and a control device which are simplified in construction for pivotally moving a carton pushing pawl.
  • the present invention provides an apparatus for feeding cartons which comprises a guide for holding the carton in alignment with a mandrel outwardly thereof while rendering the carton free to move inward toward the mandrel or outward away therefrom, a slider reciprocatingly movable inward and outward along the guide, a carton pushing pawl pivotably mounted on the slider so as to be pivotally movable between a position of engagement with the carton as held by the guide and a nonengagement position, and means for pivotally moving the carton pushing pawl toward the engagement position when the slider moves inward and pivotally moving the pawl toward the nonengagement position when the slider moves outward.
  • the apparatus is characterized in that the pivotally moving means comprises a spring for biasing the carton pushing pawl in a direction to pivotally move the pawl from the nonengagement position to the engagement position, the carton pushing pawl being pivotally movable with the outward movement of the slider from the engagement position to the nonengagement position against the biasing force of the spring by coming into contact with the inner end of the carton as held by the guide and further movable with the slider from the inner end of the carton to the outer end thereof along the outer surface of the carton.
  • the pivotally moving means comprises a spring for biasing the carton pushing pawl in a direction to pivotally move the pawl from the nonengagement position to the engagement position, the carton pushing pawl being pivotally movable with the outward movement of the slider from the engagement position to the nonengagement position against the biasing force of the spring by coming into contact with the inner end of the carton as held by the guide and further movable with the slider from the inner end of the carton to the outer end thereof along the outer surface of the carton.
  • the pivotally moving means comprises a spring for biasing the carton pushing pawl in a direction to pivotally move the pawl from the nonengagement position to the engagement position, is pivotally moved with the outward movement of the slider from the engagement position to the nonengagement position against the biasing force of the spring by coming into contact with the inner end of the carton as held by the guide and is further moved by the slider from the inner end of the carton to the outer end thereof along the outer surface of the carton. Accordingly, there is no need to attach a drive source to the slider for pivotally moving the carton pushing pawl, but the slider needs to be provided with the spring only. This reduces the weight of the reciprocatingly movable portion including the slider.
  • FIG. 1 shows an intermittently driven rotary body 12 having radial mandrels 11 for forming carton bottoms.
  • One of the mandrels 11 is stopped as inclined outwardly downward at a feed station S, at which a carton feeder is disposed.
  • the feed station S comprises an outer receiving position S1 and an inner standby position S2 which are outward from and in alignment with the mandrel 11 stopped at the station.
  • the carton feeder comprises a guide 21 for holding a carton C in alignment with the mandrel 11 outwardly thereof while rendering the carton free to move inward or outward, a magazine 22 disposed obliquely above the guide 21 and containing flat cartons C as stacked up, a transfer device 23 for withdrawing cartons C one by one from the magazine 22, transferring the withdrawn carton C to the receiving position S1 while opening the carton from the flat form to a tubular form of rectangular to square cross section and causing the guide 21 to hold the tubular carton C, and a loader 24 for transporting the carton C as held by the guide 21 from the receiving position S1 to the mandrel 11 via the standby position S2.
  • the guide 21, magazine 22 and transfer device 23, except for the loader 24, each serve as one of two units which are identical in construction although oriented in opposite directions transversely of the feeder.
  • the guide 21 comprises a pair of outer upper and lower guide rails 31, 32 arranged at the outer receiving position S1, and a pair of inner upper and lower guide rails 33, 34 arranged at the inner standby position S2.
  • the outer guide rails 31, 32 are formed respectively with opposed guide recessed portions 35, 35 shaped in conformity with the corner of the carton C opened to the tubular form.
  • the inner guide rails 33, 34 each have a guide face carrying a row of guide rollers 36 instead of the recessed portion 35.
  • the lower 34 of the inner upper and lower guide rails 33, 34 is provided at its outer end with a retainer piece 37 for preventing the carton from moving reversely.
  • the retainer piece 37 has a projection 38 projecting into the path of transport of the carton.
  • the loader 24 comprises a guide rod 41 extending between the right and left guides 21 in parallel to the path of transport, a sleevelike slider 42 slidably fitted around the guide rod 41, right and left two outer carton pushing pawls 44 extending laterally away from each other and fixed to the outer end of the slider 42 on opposite sides thereof each by an outer bracket 43 L-shaped when seen from above for pushing the carton C as held by the guide 21 at the receiving position S1 from this position S1 to the standby position S2, and right and left two inner carton pushing pawls 47 pivotally movable toward or away from each other and attached to the inner end of the slider 42 on opposite sides thereof each by an inner bracket 45 L-shaped when seen from above for pushing the carton C as held by the guide 21 at the standby position S2 from this position S2 to the mandrel 11.
  • a pivotal arm 51 has an outer end linked by a connecting rod 52 to the slider 42 and a base end fixed to a horizontal shaft 53 rotatable by an unillustrated drive mechanism (see FIG. 1).
  • the right and left outer carton pushing pawls 44 are each in the form of a strip and have an outer end extending into the path of transport of the carton which is guided by the guide 21.
  • the inner bracket 45 is provided at its inner end with opposed horizontal walls 61. Connected between these walls 61 are a spring mount plate 62 positioned at their outer ends and a pivot 63 close to these outer ends.
  • a rectangular parallelepipedal mount block 64 is positioned between the opposed walls 61 and rotatably mounted on the pivot 63.
  • Each inner carton pushing pawl 47 is in the form of a strip plate having a base end fixed to the block 64 and extending inward from the block 64.
  • the pawl 47 carries a contact roller 65 close to its inner end. (The roller 65 projects upward from the left pawl 47 or downward from the right pawl 47 as shown in FIG. 6.)
  • Each inner carton pushing pawl 47 has a V-shaped engaging notch 66 formed in its inner end.
  • a stopper arm 67 extending outward as opposed to the spring mount plate 62 has a base portion fixed to the mount block 64.
  • the spring mount plate 64 and the stopper arm 67 have attached to their opposed surfaces a recessed spring retainer 68 and a projecting spring retainer 69, respectively.
  • a coiled compression spring 71 is provided between the two retainers 68, 69.
  • Extending through the stopper arm 67 in screw-thread engagement therewith is a stopper bolt 72 positioned close to the outer end thereof and bearing at its forward end against the base portion of the inner bracket 45.
  • a position adjusting nut 73 is screwed on the stopper bolt 72.
  • the arrangement described renders the inner pawl 47 pivotally movable between an engagement position indicated in solid lines in FIG. 7 and a nonengagement position indicated in broken lines in the drawing, further biasing the pawl 47 toward the engagement position.
  • the engagement position of the pawl 47 is adjustable by rotating the stopper bolt 72 with the position adjusting nut 73
  • the slider 42 moves rearward, whereupon the outer pawl 44 moves outward as it is, while the roller 65 on the inner pawl 47 is brought into contact with the inner end of the carton C in the standby position S2 to compress the spring 71, whereby the inner pawl 47 is pivotally moved from the engagement position to the nonengagement position.
  • the roller 65 is rolled along the outer surface of the carton C and moved past the carton C, whereupon the inner pawl 47 returns to the original engagement position. Even if the carton C acts to move by being pushed outward upon the roller 65 coming into contact with the carton C, the retainer piece 37 prevents this movement.
