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 made of corrugated cardboard are held in their cutting magazine in an inclined position inclined in the conveying direction of the conveying path.
the bottom cut of this sloping stack of cuts is detected by the application device at a section forming the packaging base and placed on the conveyor line on an essentially elliptical path between the drivers of a pair of drivers and held until the two drivers form a packable package Have preformed intermediate form.
the present invention therefore has the task of eliminating the disadvantages mentioned in a device of the type mentioned at the outset.
the solution according to the invention allows air to enter unhindered between the blanks in the magazine and fanned out when they enter the magazine, thereby eliminating the risk of the second front blank being carried away. Furthermore, adapting the suction pads to other cutting formats can be carried out comparatively easily and quickly.
the device described with reference to FIGS. 3 and 4 serves for preforming a package 1 (FIG. 1) into a fillable intermediate form.
the package 1 consists of a bottom B, a front wall F, a rear wall R, a lid D and adjoining side flaps S and a closing flap V attached to the rear wall R.
the side flaps S glued together form the side walls which, depending on the size of the Side lobes - can be open or closed.
the sealing flap V is also glued to the cover D. All of these packaging parts are made in one piece from a flat blank 2 (FIG. 2) and only separated from one another by fold lines or fold grooves 3 and 4 or by notches 5.
it is first preformed into an intermediate shape by folding the front wall F with the cover D and on the other hand the rear wall R with the flap V at right angles upwards about the corresponding folding lines 3.
the side tabs S are still coplanar from the adjacent box section B, F, R or D.
the packaging material is pushed from the side onto the base B and then the remaining parts are folded over to form the finished packaging and glued together.
blanks 2 For the periodic application of blanks 2, they are provided vertically in a magazine 6 on a height-adjustable floor 7. An upper and a lower retaining strip 8 prevent the foremost blank 2 from falling out of the magazine 6 with little resistance.
This is continuously fed with blanks from a conveyor belt 9 which runs obliquely downwards and is adjustable in its inclination, these blanks being conveyed at point 10 first to the system come with the blanks in the magazine. They are then fanned out by the conveyor belt 9 at the foot end so that air can pass between the individual blanks before they are lined up at least approximately vertically on the floor 7.
a conveyor section 11 connects to the magazine 6 and transports the blanks 2 preformed into an intermediate form to the subsequent filling stations of a packaging machine.
the conveyor section 11 is essentially formed by an endless chain pair 12 driven by a motor (not shown), the conveying and pulled strand of which moves in a conveyor plane 13 in the direction of the arrow shown.
the chain pair 12 is guided around two deflection wheels 14, which are freely rotatably seated on a freely rotatable shaft 15 and which is occupied by regularly spaced pairs of drivers 16.
Each pair of carriers 16 has carriers 16 'preceding and trailing carriers 16''in the conveying direction, which are provided on the sides facing one another with flanks oriented at right angles to the conveying plane 13.
the driver pairs 16 pass around the deflection wheels 14 from the lower chain center to the conveying plane 13 during the rotation of the drivers 16 ', 16' 'and, as described later, take over a cut 2.
the shaft 15 is in two vertical, parallel ones Plates 19, between which the pair of chains 12 rotates, rotatably mounted.
a roller 20 is seated in a rotationally fixed manner on the shaft 15, on the circumference of which rubber-elastic rings 21 are placed in the manner of solid rubber tires.
the outer diameter of the rings 21 is somewhat larger than the pitch circle diameter of the chain deflection wheels 14, so that the peripheral speed of the rings 21 is greater, preferably approximately 5% to 10%, greater than the conveying speed of the chain pair 12.
a guide plate 23 covering the rollers 20 is fastened to the plates 19, which is oriented parallel to the conveying plane 13 and which forms a smooth sliding surface on its underside.
the guide plates 23 begin shortly before the shaft 15 and end near or at the end of the inlet area 17.
the device has an eccentric drive 24 which pivots a rocker 25 in the conveying direction between the end positions shown.
the rocker 25 is connected by two links 26 to a slide 27, which can be moved in a straight line on guides 28 parallel to the conveying direction.
the guides 28 are fastened to the plates 19 on the sides facing away from one another.
a tube 29 is rotatably mounted, on which a pinion 30 is seated in a rotationally fixed manner.
From the pipe 29 cross three lead angular pipe pieces 31 which carry rubber-elastic suction nipples 32 at the free end, which form a suction pad.
the tube 29 is connected via a controllable valve (not shown) to a vacuum source (also not shown), so that the suction nipples 32 can be acted upon with either vacuum or normal pressure in the machine cycle.
the pinion 30 meshes with a toothed rack 33 which is fixedly connected to the piston rod of a hydraulically or pneumatically drivable piston drive 34 fastened on the slide 27. If the piston drive 34 is acted upon by a medium, the tube 29 rotates by 90 °, as indicated in FIG. 3.
the setup described works as follows.
the continuously rotating pair of chains 12 brings a pair of drivers 16 into the inlet area 17 with each machine cycle. While the preceding driver 16 'reaches the conveying plane 13, the teats 32 in the position shown in FIG. 3 with solid lines (in which they act on vacuum) are) the foremost blank 2 in the magazine 6 in the area of the front wall F and preferably also the cover D.
the eccentric drive 24 now moves the slide 27 - before the trailing driver 16 '' reaches the inlet section 17 - into the other end position.
the suction nipples 32 pull off the front wall F and the cover D of the cut 2 in the conveying direction, the captured ones Cut sections F and D keep their vertical orientation.
the carriage 27, which is driven essentially at the same speed as the peripheral speed of the rings 21, reaches the other end position (position 37) after the take-over of the blank 2 by the rollers 20, but at the latest when the rollers 20 stop the blank 2 with the preceding driver 16 brought.
the suction nipples 32 are subjected to normal pressure, so that they release the blank 2; at the same time or subsequently, they are pivoted outward from the conveying path of the blank 2 by activating the piston drive 34 by 90 °. Then the carriage 27 moves to the other end position and the workflow described is repeated.
a finger-shaped, flat hold-down plate 40 with each of the two slides 27 or with the suction nipples 32, each of which around an axis parallel to the tube 29 are pivotable.
the hold-down plates 40 lie in the conveying plane 13. Their upper side lies slightly lower than the underside of the guide plates 23.
the hold-down plates 40 are in the notches 5 of the foremost one lying in the conveying plane 13 Cutting 2 pivoted. They remain in these notches and follow the suction nipples 32 while the blank 2 is being deposited until they have exceeded the position 35 and the lower edges of the notches 5 lie under the guide plates 23 and are caught by the rollers 20.
the trailing driver 16 'of the incoming driver pair 16 moves from below onto the conveying plane 13. In doing so, it pivots the rear wall R with its side tabs S and the closing tab V. up the corresponding fold line 3 until it abuts its leading flank and is oriented at right angles to the conveying plane 13.
the side tabs S of the bottom B are held down by the guide plates 23, so that the bottom B moves forward in the conveying plane 13. With swinging up the rear wall R completes the preforming of the packaging into a fillable intermediate form and the preformed packaging is transported, so to speak, clamped between the drivers 16 'and 16''of a driver pair 16 to a subsequent filling station.
rollers 20 not only drive the side tabs S of the base B but also the cut portions B, R and V following the cut portions F and D in the direction of the arrow 36, they also have the function of a guide element which pulls the cut portions drawn from the base B. Lead R and V into a position in which they can be reliably detected by the trailing pair of drivers 16 ′′ and then pivoted upwards in the vertical.
the application device can also be designed differently. It is essential that the grippers 32 transfer the front wall F of the blank 2 in a vertical orientation to the conveying plane 2 and in the conveying direction of the conveying path 11 and that the packaging base B is held in a form-fitting manner in the conveying plane 13 during the preforming of the blank 2 into a fillable intermediate shape.
the guide plates 23 instead of the guide plates 23, other hold-down elements such as rollers or the like can be provided.
