Definitions

  • DE-B 25 03 403 describes a spreading mechanism whose spreading fingers can only be moved via linearly active elements. This requires a heavy-weight construction, which reduces the working speed.
  • the spreading fingers are pivoted throughout the spreading process as well as during lifting and lowering about axes which are oriented transversely to the conveying direction.
  • a precise, that is to say as free of play as possible, guidance of the spreading fingers is only possible with this device because of the numerous pivot bearings with a sufficiently heavy construction, which prevents a high working speed.
  • the invention also facilitates the particularly advantageous embodiment according to claim 3, which supports the closing of the bags by evacuating the upper end of the bag. At the same time, dust emissions are suppressed.
  • a commercially available sewing device 12 is attached to the jacket 10 and sews the passing bags at the upper end. Since the special design of such a sewing device has no influence on the present invention, its description is omitted.
  • a folding device 13 is fastened to the jacket 10 with the folding strips 14 and 15, the upper folding edge of the folding strip 14 determining the effective direction of the folding device 13, i.e. the folding line.
  • the folding device 13 is, seen in the conveying direction 4 of the conveyor section 3, in front of the sewing device 12. Like the sewing device 12, it is a known unit and has no influence on the present invention with regard to its design.
  • a carrier 19 and a frame 16 are further attached, which consists of two longitudinal guides 17 and 18 and two vertical struts 19th and 20 exists.
  • a support element in the form of a slide 30 for the spreading fingers 21 in the conveying direction (arrow 4) of the conveying path 3 is displaceably mounted to and fro.
  • Two swivel axes 36 and 37 are fixedly arranged in the slide 30, about which angle levers 38 and 39 are pivotably mounted.
  • the mutually facing legs of the angle levers 38 and 39 are connected to one another by a joint member 40, whereas the ends of a pneumatic cylinder-piston unit are articulated on the other legs at 41 and 42, respectively.
  • a suction pipe 45 is fastened to the bearing housing 32 by means of a pipe clamp 44, which ends over the downward ends of the spreading fingers 21 and widens in a funnel shape against them.
  • An armored corrugated hose 45 is connected to the suction pipe 45 and leads to a suction air source, not shown. Because the suction pipe 45 is firmly connected to the bearing housing 32, the dust extraction is always in the immediate vicinity of the spreading fingers 21 and thus, during a spreading process, directly above the upper end of the bag, i.e. at the location where the dust develops.
  • FIGS. 7 to 14 FIGS. 7, 9, 11 and 13 showing views of the spreading device shown in simplified form and FIGS. 8, 10, 12 and 14 are plan views of the preceding figure.
  • the cylinder-piston units 23 Hold the closing strips 23 in their spread position so that the bag 52 can move between them without interference.
  • the carriage 30 assumes its end position remote from the column 9, in which the piston rod of the cylinder-piston unit 34 extends and the bearing housing 32 is pivoted upwards with the spreading fingers 21.
  • the piston rod of the cylinder-piston unit 43 is retracted so that the spreading fingers 21 assume the adjacent position.
  • the sack 52 actuates the sensor of a switch E 1, as a result of which the motor 37 and the cylinder piston units 34 and 43 are actuated, so that the carriage 30 moves at the same speed with the conveyor path 3 and the bearing housing 32 with the spreading fingers 21 is lowered and the spreading fingers 21 are moved apart to carry out the spreading movement.
  • the ends of the spreading fingers 21 dip into the open end of the bag.
  • the carriage 30 actuates a switch E 2, which activates the cylinder piston units 23 'for a closing movement.
  • the closing strips 23 lie at the upper end of the sack against the sack walls held in parallel alignment by the spreading fingers 21 and form a narrow guide slot in which the upper end of the sack can slide with the sack walls lying against one another.
  • the switch E 3 which actuates the cylinder piston unit 43 and moves the spreading fingers 21 against each other. He also activates the cylinder piston units 23 'and 34 in such a way that the closing strips 23 are spread and the spreading fingers with the bearing housing 32 are pivoted upward out of the bag 52.
  • switch E 4 switches motor 47, which moves carriage 30 back against vertical strut 20, where it actuates switch E 4, which switches motor 47 off (FIGS. 7 and 8).
  • the column 9 can be pivoted by actuating the motor 28 until the fold edge of the lower fold bar 14 or the longitudinal guides 17 and 18 are aligned parallel to the conveyor line 3 are, which ensures a straight folding and sewing of the bag end.
