Definitions

  • the invention relates to a device for feeding a packaging blank to a packaged product, with a first feed device, from which the packaged goods reach a second feed device, through which it is moved in the transport direction, the second feed device Has at least one driven lower belt for feeding the packaged goods, with a blank holder that can be fed to a blank, and with a pressing device for moving the blank from the blank holder into a predetermined position relative to the packaged goods.
  • the blank must be fed to the packaging material in a predetermined position relative to it, so that the blank can be folded around the packaging material.
  • the packaged goods should not be completely folded into the blank, but should only be fed to one side of the packaged goods a flat blank, which can be folded in part around other sides of the packaged goods.
  • the packaged goods are then packed together with the adjacent blank, which is often also referred to as a card, in a transparent film or the like.
  • the product initially passes from a first feed device to a second feed device, through which it is moved further in the transport direction.
  • the second feed device usually has a driven lower belt, to which a corresponding parallel upper belt can be assigned.
  • the packaging blank is in this arrangement in the area fed vertically from above between the first and the second feed device.
  • the blank initially falls vertically from a chute into a blank receptacle, which is arranged in the transport direction and is arranged before the start of the lower belt.
  • the first feed device with a slide on which the packaged goods lie moves laterally against the blank protruding vertically upwards from the blank holder.
  • the blank is folded approximately U-shaped around the packaged goods at predetermined folding edges and is finally pushed forward by the slide between the lower belt and the upper belt of the second feed device, which take over the further transport.
  • the reciprocating movement of a slide can be achieved mechanically in a relatively complex manner.
  • only a folded blank can be fed to the packaged goods with the previously known arrangement. Since the slide is pushed vertically together with the packaged goods against the blank, this results in the blank being folded around the packaged goods by at least one folded edge.
  • the present invention is therefore based on the object to improve a device of the type mentioned in such a way that its structure is simplified and not only a folding of the blank around the packaged goods is possible, but optionally also the supply of a flat blank to one side of the packaged goods is achievable.
  • this object is achieved in that, in a device of the type mentioned at the outset, the blank holder between the first feed device and the second feed device is arranged at least partially below the lower belt, in that the pressure device has a pressure roller which is arranged axially parallel to a roller via which the lower belt is guided at the end, and which can be advanced in the direction of the roll, until a blank held between the pressure roller and the roll in the blank holder is carried along by the driven lower belt, and that the pressure roller is assigned a guide element for articulating the blank to the lower belt.
  • a slide can be dispensed with entirely, and the packaged goods can be transported, for example, by a belt to the second feed device.
  • the position of the blank can be predetermined in such a way that either the blank is folded around the packaged goods or a flat contact of the blank on the underside of the packaged goods.
  • the blank protrudes vertically upwards from the blank receptacle when the packaged goods are pushed against the blank, the blank folds around the packaged goods, as is also the case with a conventional arrangement.
  • the blank has already at least partially with its end by pressing the pressure roller against the end roller of the lower belt as a result of the guide element from a vertical position towards the end roll of the lower belt, a subsequent or simultaneous feeding of the packaging leads to the blank laying flat on the underside of the packaging.
  • the cut receptacle viewed in the transport direction, is arranged approximately perpendicular to the transport direction before the start of the lower belt.
  • This measure has the advantage that the blank can be fed to the blank holder in a particularly simple manner, namely, for example, vertically from above.
  • the pressure roller and the pressure element are fixed to the free end of a roller holder which is rotatably mounted about its other end.
  • the blank can be pressed against the roll of the lower belt by a simple pivoting process.
  • a lifting cylinder acts on the roll holder, by means of which the roll holder can be pivoted against the end roll of the lower belt until the pressure roll comes to rest on the roll or on a blank lying against it.
  • the pivoting movement can be carried out in a particularly simple manner, e.g. with the help of a pneumatic cylinder.
  • the guide element is designed as a guide plate, the end of which, when the pressure roller rests on a blank lying against the roller, projects from the pressure roller for pressing the blank against the roller.
  • the area of the guide plate protruding from the pressure roller is preferably concavely curved with respect to the pressure roller.
  • a dispenser is arranged vertically above the blank holder for feeding blanks into the blank holder, from which a blank falls into the blank holder upon receipt of a release signal.
  • the donor can be designed as a single donor or in the form of a magazine.
  • the blank holder is arranged to be adjustable in the vertical direction.
  • the first feed device has a sensor element; which emits a signal when a packaged product is fed into a predetermined position, which signal is fed to a control device via which the feeding of a blank into the blank holder and the feed movement of the pressing device can be controlled.
  • a second roll is preferably arranged axially parallel to the latter in order to support the entry of the packaging material into the second feed device.
  • an upper belt parallel to the lower belt is guided over this second roller, whereby a safe transport of a packaged product introduced into the second feed device is ensured together with the packaging blank.
  • the device according to FIG. 1, which is denoted overall by the number 10, has a first feed device 20 and a second feed device 30, which are arranged one behind the other and through which a packaged product 28 can be moved translationally in the transport direction 34.
  • the first feed device 20 is designed as a simple lower belt on which the packaged goods 28 rest.
  • the second feed device 30 has a lower belt 12 and an upper belt 16 arranged above it and parallel to the lower belt 12, with both belts 12, 16 being axially parallel to one another Rollers 14, 18 are guided at the ends.
  • the lower belt of the first feed device 20 and the lower belt 12 of the second feed device 30 are arranged substantially horizontally one behind the other at a short distance from one another, so that a product to be packaged 28 from the first feed device 20 beyond the end roller thereof to the two belts 12, 16 can be advanced to the second feed device 30, which then take over the further transport of the packaged goods 28 in the feed direction 34.
  • the lower belt 12 and upper belt 16 of the second feed device 30 are each suspended at the ends on stationary vertical supports 48 and 50 of the machine frame.
  • a flat dispenser 22 is arranged vertically, in which blanks 26 are held in a slot-shaped receptacle and can be dispensed downward if necessary, for which purpose a drivable pair of rollers 24 is provided.
  • a flat, upwardly open cut receptacle 36 is arranged vertically below the dispenser 22 and is adjustably fixed in the vertical direction via an adjusting device 37 on the fixed support 50.
  • the upper ends of the blank receptacle 36 are bent outwards in order to ensure the secure insertion of a blank falling out of the dispenser 22 downwards.
  • the blank holder 36 is vertically adjustable within wide limits in order to allow adaptation to the different blank lengths, the upper adjustment range being limited by the lower end of the roller 14 of the lower belt 12.
  • a pressure device On the lower support 50, a pressure device, designated as a whole by the number 40, is held with a roller holder 42 by means of two mutually parallel L-shaped supports, which are connected by a common cross strut (not recognizable in the view according to FIG. 1).
  • the two L-shaped supports are pivotally attached to the lower support 50 by the two ends 52 of their shorter legs.
  • a pressure roller 38 is rotatably mounted between the two ends of the longer, freely projecting legs of the roller holder 52.
  • a guide element 46 in the form of a guide plate is also fastened to the roller holder 42, which is curved concavely with respect to the pressure roller 38 and with its end upward in the direction of the pressure roller 38 via an imaginary extension line of the roller carrier 42 protrudes onto the end roll 14 of the lower belt 12.
  • a lifting cylinder 44 designed as a double-acting pneumatic cylinder engages on the roller holder 42, via which the roller holder 42 can be pivoted with its end pressure roller 38 against the roller 14 of the lower belt 12.
  • a sensor element 32 in the form of a light barrier is also provided above the first feed device 20 and is connected to a control device 35, which is only indicated schematically. If a packaged product 28 is advanced on the first feed device 20 until the beam path of the light barrier is interrupted, the delivery of blanks via the pair of rollers 24 or a movement of the lifting cylinder 44 can be controlled via the control device 35 with the aid of the switching pulse received, as by the dashed lines in Fig. 1 is indicated.
  • the previously described device according to FIG. 1 functions in the following way:
  • the pair of rollers 24 is activated in order to dispense a packaging blank from the dispenser 22 into the blank holder 36 arranged vertically below it.
  • the blank falls vertically into the blank holder and is held in the position indicated by the number 26 in FIG. 1, which is dependent on the vertical position of the blank holder 36.
  • the blank 26 protrudes vertically upwards beyond an imaginary extension line of the upper belt 16 up to the roll 18 of the upper belt.
  • the lifting cylinder 44 In response to a control impulse from the control device 35, the lifting cylinder 44 is extended so that the roller holder 42 is pivoted in the direction of the roller 14 of the lower belt 12 until the pressure roller 38 rests on the blank 26 ', so that the blank 26' between the pressure roller 38 and roller 14 of the lower belt 12 is held and transported upwards by the lower belt 12 (FIG. 2).
  • the blank 26 ' is pressed against the roller 14 by the guide element 46, so that the blank lies against the roller 14.
  • the packaged goods 28 are advanced further in the transport direction 34 by the first feed device 20, so that the front end of the packaged goods 28 bears against the blank 26 '.
  • the blank 26 ′ folds in around the front end of the packaged goods 28 with two folding edges provided at these locations of the blank 26 ′.
  • the packaging material 28 is now together with the blank 26 'between the lower belt 12 and upper belt 16 of the second feed device 30 is moved further.
  • the vertical position of the blank holder 36 was changed in such a way that the blank 26 '' with its end projecting upwards runs into the area between the lower belt 12 and the upper belt 16 as a result of the guide element 46 and does not follow beyond the front edge of the roll 18 of the upper belt 16 protrudes above. If the packaged goods 28 are simultaneously pushed from the first feed device 20 into the second feed device 30 between the lower belt 12 and the upper belt 16, the blank 26 ′′ lies flat against the underside of the packaging goods 28 when the lower belt 12 and the upper belt 16 are driven further .
