Definitions

  • the present invention relates to a device according to the preamble of claim 1.
  • a device of this type is known from CA-PS 1 288 990.
  • the flat packaging blanks are in their blank magazine made of corrugated cardboard in a conveying direction of the conveyor line inclined inclined.
  • the bottom cut this sloping stack of blanks is used by the feeder on a section forming the packaging base captured and on an essentially elliptical orbit between the carriers of a pair of carriers placed on the conveyor line and held on until the two drivers the packaging is preformed into a fillable intermediate form to have.
  • the present invention therefore has as its object a device of the type mentioned the disadvantages mentioned to eliminate.
  • Air can flow freely through the solution according to the invention between those in the magazine and when entering the magazine fan-out cuts occur, which increases the risk of entrainment of the second front blank is banned.
  • the device described with reference to FIGS. 3 and 4 serves the preforming of a packaging 1 (FIG. 1) into a fillable one Intermediate form.
  • the package 1 consists of a bottom B, a front wall F, a rear wall R, a lid D and adjoining side tabs S and a flap attached to the rear wall R. V.
  • the side tabs S glued together form the Side walls that - depending on the size of the side flaps - open or can be closed. With the finished packaging is also the sealing flap V is glued to the cover D.
  • All these Packaging parts are in one piece from a flat blank 2 (Fig. 2) manufactured and only by fold lines or fold grooves 3rd and 4 or separated by notches 5.
  • the packaging 1 is initially in an intermediate form preformed by the front wall F with the cover D and on the other hand the rear wall R with the flap V around the corresponding fold lines 3 are folded upwards at right angles.
  • the side tabs S are still in the preformed packaging coplanar from the adjacent box section B, F, R or D. That is in the preformed packaging for this intermediate form Packaged goods pushed from the side onto the floor B and The remaining parts are then used to form the finished parts Packaging folded and glued together.
  • a conveyor section 11 connects to the magazine 6 and closes an intermediate form preformed blanks 2 to the following Fills filling stations of a packaging machine.
  • the conveyor line 11 is essentially an endless one Motor driven chain pair 12, not shown, formed whose promoting and drawn strand is in one level 13 moved in the direction of the arrow.
  • the pair of chains 12 is guided around two deflection wheels 14, which are free to rotate sit on a freely rotatable shaft 15 and with regularly spaced driver pairs 16 is occupied.
  • Each Driver pair 16 has previous drivers in the conveying direction 16 'and trailing driver 16' 'on each other facing sides with the conveyor plane 13 oriented at right angles Flanks are provided.
  • the driver pairs 16 occur along an inlet path 17 during of the rotation of the drivers 16 ', 16' 'around the deflection wheels 14 from lower chain center to the conveyor level 13 and take over how described later, a blank 2.
  • the shaft 15 is in two vertical, parallel plates 19, between which the pair of chains 12 rotates, rotatably mounted.
  • a roller 20 is seated on the shaft 15 in a rotationally fixed manner, on the circumference of rubber-elastic rings 21 in the manner of solid rubber tires are put on.
  • the outside diameter of the rings 21 is slightly larger than the pitch circle diameter of the chain deflection wheels 14 so that the peripheral speed of the rings 21st larger, preferably about 5% to 10% larger than the conveying speed of the chain pair 12.
  • a short distance above the rollers 20 is on the plates 19th attached a guide plate 23 covering the rollers 20, which is oriented parallel to the funding level 13 and that on his Underside forms a smooth sliding surface.
  • the baffles 23 start shortly before wave 15 and end near or at the end of Entry area 17.
  • the device has an eccentric drive 24 which a rocker 25 in the conveying direction between the drawn End positions pivoted back and forth.
  • the rocker 25 is through two Handlebar 26 each connected to a carriage 27 which on the conveying direction parallel guides 28 are linearly displaceable.
  • the guides 28 are on the plates 19 facing away from each other Sides attached. There is 27 in each of the two slides A tube 29 rotates freely, on which a pinion is fixed against rotation 30 sits. Three angular pipe sections lead from the pipe 29 transversely 31, which carry rubber-elastic suction nipples 32 at the free end form a suction pad.
  • the tube 29 is over a, not shown, controllable valve with a likewise not shown Vacuum source connected so that the teat 32 Vacuum or normal pressure can be applied in the machine cycle are.
  • the pinion 30 meshes with a rack 33 which is fixed to the Piston rod of a hydraulically or pneumatically drivable, on the slide 27 attached piston drive 34 is connected. If the piston drive 34 is acted upon by a medium, rotates the tube 29, as indicated in Fig. 3, by 90 °.
  • the setup described works as follows. That continuously revolving chain pair 12 brings with every machine cycle a pair of drivers 16 in the inlet area 17. During the previous Driver 16 'reaches the conveying level 13 the teat 32 in Fig. 3 with solid lines shown position (in which they are subjected to vacuum) in magazine 6 the front blank 2 in the area of the front wall F and preferably also the cover D.
  • the eccentric drive 24 moves now the carriage 27 - before the trailing driver 16 '' reaches the inlet section 17 - to the other end position.
  • the Suction nipples 32 pull the front wall F and the cover D of the detected blank 2 in the conveying direction, the detected Cut sections F and D keep their vertical orientation.
  • both carriages 27 or Suction cups 32 each have a finger-shaped, flat hold-down plate 40 to move, each around an axis parallel to the tube 29 are pivotable.
  • the hold-down plates 40 lie in the conveying plane 13. Your top is slightly lower than the bottom of the baffles 23.
  • the hold-down plates 40 in the notches lying in the conveyor plane 13 5 of the front blank 2 pivoted. In these notches they remain and follow while filing the Cut 2 the teats 32 until they exceed position 35 have and the lower edges of the notches 5 under the guide plates 23 are located and are captured by the rollers 20. At this moment, they are cut out of the funding path pivoted out and return with the teat 32 in Fig. 3 position shown back.
  • the hold-down plates 40 the lower edges of the lying in the conveyor plane 13 Notches form-fit from magazine 6 to below Baffles 23 out, which also strongly warping Blanks 2 reliably in the effective range of the rolls 20 to be brought.
  • rollers 20 Since the rollers 20 not only drive the side tabs S of the bottom B. but also those following the cutting sections F and D Blank sections B, R and V in the direction of arrow 36 swings up, they also have the function of a guide organ, that the redrawn from the bottom B cut sections R and V in lead in a position in which they follow from the trailing pair of drivers 16 '' reliably detected and then pivoted upwards into the vertical can be.
  • the application device can also be designed differently be. It is essential that the gripper 32 the front wall F of the Blank 2 in a vertical orientation to the conveyor level 2 and in Direction of conveyance of the conveyor line 11 passed and that the packaging floor B during preforming the blank 2 into one fillable intermediate form positively in the conveying plane 13 is held.
  • the guide plates 23 instead of the guide plates 23, other hold-down devices can be used such as roles or the like.
