Definitions

  • the present invention relates to a packaging device with a bag-forming machine for producing bags to be filled with goods according to the preamble of patent claim 1.
  • DE-A-37 02 391 discloses a device which has a pair of conveyor rollers which continuously feed at a uniform speed and a cross cutter, with the intermittent transfer of a blank separated from the packaging material supplied as a belt to one Folding apparatus of the bag forming machine, a feed device is arranged behind the cross cutter, which takes over the cut and feeds the folding apparatus at a higher speed than the conveying speed of the packaging material belt.
  • the conveyed packaging material strip is guided between the cutting rollers, the upper knife and the lower knife of the cross cutter and between two feed rollers to the feed device, with the use of a packaging material in which a connection is brought about by gluing is, the lower roller of the pair of conveyor rollers is assigned a glue apparatus, the glue application roller of which applies adhesive areas for the longitudinal and bottom seam of the bag to be manufactured onto the conveyed packaging material band.
  • FR-A-880.271 Another device of the type mentioned at the outset is known from FR-A-880.271, which, however, serves to fill packs with tobacco.
  • This device is provided with a mandrel wheel, on which double-layer, one-sided tubular bags are made from film rolls. The tubular bags are pushed through a transition into a cellular wheel and passed to processing stations that serve. This document corresponds to the preamble of claim 1.
  • the device according to the invention also advantageously allows glue types with a shorter setting time to be used, which enables an increase in machine performance.
  • an adhesive device and a switch is also known, which is provided to direct the bags on different conveyor tracks.
  • the bags are transported by the conveyor tracks for further processing.
  • Metal foils are used to mark the start of a new foil roll, which are scanned by a button arranged in the area of the adhesive device.
  • Such a system proves to be disadvantageous with regard to the fact that if the device for the hose production or the gluing device does not work properly, the operation of the switch is impaired because the wedge-shaped part of the switch can easily penetrate the hose sides or the longitudinal seam, so that the bag flow is interrupted. Such penetration of the wedge-shaped part between the hose sides can, however, also occur during normal operation of the system, especially if the deflection to the conveyor tracks is greater than approximately 25 ° in this area.
  • the packaging device has an input device with deflection means which, in the event of a fault in the unfolded wrapping material band, guides the beginning of an incoming unfolded band cut into a reject position before the separation device is actuated.
  • the subject of the present invention excellently avoids the disadvantages of the system mentioned, because according to the invention a simple film can be easily deflected in a space-saving manner, namely at an angle of 30 ° to 180 °, for example with a deflecting part, suction rolls, etc.
  • the 1 comprises a bag forming machine 1 for producing the bags, an input device 2 and an output device 3.
  • the input device 2 has a supply roll 4, from which the wrapping material belt 5 via two processing stations 6, 7, a control device 8, a belt conveyor system 9, a separating device 10 and a separation station 11 reaches the entrance of the bag-forming machine 1, which is used to manufacture the bags.
  • the output of the bag forming machine 1 is connected to the output device 3, which comprises two stations 12 and 13, one of which is provided for filling and the other for closing the bags, which can be filled, for example, with a bulk material.
  • a bag forming machine is shown, which essentially consists of a mandrel wheel. However, the invention is not limited to such an embodiment.
  • the second processing station (7 in FIG. 1) is implemented as a tear tape device 23 (FIG. 2).
  • the glue application device 21 can have, for example, a glue container 211 in which a relatively large rotating roller 212 is immersed, which moves a glue application roller 213, the belt 5 running between the glue application roller 213 and a counter roller 214.
  • the control device 24 (8 in FIG. 1) be provided with a light barrier
  • the belt conveyor system (9 in FIG. 1) has two conveyor rollers 251, 252 and a gear 253 (FIG. 2)
  • the separating device (10 in FIG. 1) an upper knife 261 and one by means of a further gear 262 actuated lower knife 263 (Fig. 2) comprise.
  • a motor 27 is provided for driving the roller 212, the tear tape device 23 and the gears 253 and 262.
  • the guide wing 2 comprises a guide wing 281, which can be pivoted about an axis 282 by a pivot mechanism 283, and a separating container 284.
  • the guide wing 281 has an upper flat side which extends from the region of the axis 282 to the region of the knives 261 and 263 extends.
  • the edge of this flat side in the area of the knives has an extension 285 which is curved downwards in a concave manner.
  • the wrapping material 5 is passed in a known manner from the supply roll 4 through at least one processing station and cut into sections in the separating device. This means that in practice one of the two processing stations shown can be omitted. If the control device 8 detects an error that has arisen, for example, in the first or in the second or in both processing stations, a corresponding error message is generated, which, via an electrical or electronic or fluidic or mechanical or combined control device (not shown in FIGS. 1 and 2), actuates the pivoting mechanism 283, which moves the guide wing 281 upwards, in such a way that the cut-off wrapping material, for example a packaging paper sheet, against the extends concavely bent downward extension 285 and thus falls into the separating container 284 underneath. Faulty sections can thus be removed without interrupting operations.
  • the separating device includes, for example, a tear-open belt device 31, a control device 32, a belt conveyor system 33 and a separating device 34 of the type mentioned.
  • the separating device according to FIG. 3, however, has a deflection device 35 with a so-called suction roller, in which the suction effect only then takes place when the control device 32 reports an error. Since the suction roll is located below the wrapping material web, the suction effect causes the front of the packaging paper sheet to adhere to the rotating suction roll, which results in deflection of the sheet, which is then no longer passed on to the bag-forming machine, but rather into its own weight waste container 36 lying below falls into it.
  • a tear tape device 41 includes, for example, a tear tape device 41, a control device 42, a belt conveyor system 43, a separating device 44 and a suction roller 45, which is located above the wrapping material web, so that the defective sheets are conveyed into a horizontally arranged separating container 46 by the tangential force of the rotating suction roller 45.
  • a tear-open belt device 51 comprises, for example, a tear-open belt device 51, a control device 52, a belt conveyor system 53, a separating device 54 and a fixedly arranged guide wing 55 with a concavely bent downward extension, in the area of which the opening of a separation container 56 is located. 5, however, has an additional blowing nozzle 57, which is only actuated when the control device 52 reports an error in order to push the front side of an incoming sheet downward by the air flow from the blowing nozzle 57, so that the sheet falls into the separating container 56.
  • the circuit according to FIG. 6 has a pulse generator 61, which emits a shift pulse per belt section or scissor stroke, which is fed to the input of a shift register 62, 63, 64 with an adjustable number of steps, the control signal of the tear tape via a switch 65 another input of the shift register 62, the control signal of another parameter, for example the centering, a further input of the shift register 63 via a switch 66 and the control signal the starting condition is fed to a further input of the shift register 64 via a delay switch 67.
  • the outputs of the shift registers 62, 63, 64 are connected to a fluidic valve circuit 68 which is actuated only when a signal occurs at the output of a shift register, the signal being present during a full cycle, ie until the next shift pulse arrives.
  • the shift registers 62, 63, 64 are designed to be adjustable because the processing stations 6; 7 or 21; 23, 31, 41, 51 and the control devices 8 and 24, 32, 42, 52, 67 are arranged at a distance of, for example, 1 to 3 section lengths 5 'from the separating devices 261, 263 and 34, 44, 54, respectively that if a smaller section length is desired, the shift registers can be reset.
  • the control signal of the tear tape is only emitted if the tear tape device malfunctions, that is to say the device for cyclically attaching the tear tapes that tear the consumers apart around the package to open.
  • the control device 24 for example a light barrier, actuates a relay circuit 65 '(Fig. 2) which has a switch 65 (Fig. 6) which is closed when the tear tape is incorrectly attached. If the shift register 62 has received the set number of pulses from the pulse generator 61, compressed air via the feed A and the fluidic valve circuit 68 as compressed air A '(FIGS. 2 and 6), the pneumatic cylinder of the swivel mechanism 283 (FIG. 2) or the blow nozzle 57 (Fig. 5) fed so that the section 5 'is eliminated.
  • the delay switch 67 responds only after a predefined step status time, which corresponds, for example, to the time after which the glue has dried in, the intended delay time also being adjustable.
  • the delay switch 67 thus serves as a control device for the glue specification. For example, assume that the delay switch 67 is set to 30 seconds and that the machine stops and is started again after 20 seconds; in this case the glue does not dry out with a longer setting time, but no section 5 ′ is also excreted; this prevents loss of film. If, on the other hand, a glue is used, the setting time of which is shorter, and the delay switch is set, for example, to 15 seconds, sections 5 'are eliminated with a machine downtime of 20 seconds.
  • the suction rollers 35, 45 (Fig. 3,4) can be acted upon by the suction air marked with the arrows B / B '(Fig. 6) instead of the compressed air marked with the arrows A / A' (Fig. 6).
  • a method can be provided in which a faulty band section is only cut off when the beginning of the band section has already been passed into the reject position.
  • the guide wing 281 can also be arranged such that the distance between the extension 285 and the knives 261, 263 is greater than the film length 5 '. In this case, the defective band section 5 'is first separated from the band 5 by the knives 261, 263 and then the front edge is deflected by the curved extension 285.
