Definitions

  • the invention relates to a method for producing, filling and closing bags from a tubular film web made of thermoplastic material, preferably provided with side gussets, according to the preamble of claim 1.
  • the sections that later form the sack are pulled off a hose chain according to a previously known method.
  • This hose chain is perforated at predetermined intervals so that the sections corresponding to the later sack can be torn off at the perforation.
  • the individual tube sections are fed to a filling funnel for filling, for example with a granulate.
  • the open sacks are removed, pulled tight on their open side and sealed in a specially provided edging device.
  • the generic method can also be carried out, for example, by a device according to DE-OS 37 15 685.
  • This device has sliding and preferred rollers through which the front end of the tubular film web, which is each provided with a cross-weld seam, is pushed freely in a vertical direction intermittently by one bag or sack length between welding jaws of a welding device which execute opening and closing movements in a horizontal plane.
  • a cross cutting device is arranged below the welding jaws and below this cross cutting device are arranged in pairs grippers provided on a transport device which hang the bags or sacks separated from the tubular film web and provided with bottom weld seams with a horizontal conveying direction over a cooling section for cooling the cross weld seams to a filling station Feed transporting transfer device.
  • the transport device consists of a hub-like support piece rotatably mounted about a vertical axis with radial arms, at the free ends of which the grippers provided in pairs are arranged.
  • the cooling section consists, as it were, of a cooling carousel, which feeds the bag workpieces provided with the transverse weld seams and separated from the tubular path from the welding station on a circular path to a device for transferring the bag workpieces to the filling station. If this device has, for example, four radial arms, a welding device and a cutting device are located above the first station.
  • a sack already provided with a transverse weld seam is inserted into the first opened pair of grippers from above in each cycle for the production of a sack, and is preferably gripped and cut off over a sack length.
  • a new cross weld seam is then formed at the end of the tubular path, while the cooling carousel rotates intermittently through an angle of 90 ° and remains in this position until another sack with a cross weld seam has been inserted into the subsequent station.
  • the sack is filled with a predetermined amount of filling material, a predetermined weight of filling material usually being filled in.
  • the filling material for example a granulate to be filled, has different bulk volumes with the same weight. This is due, for example, to a different moisture content in the bulk material. Due to the different bed heights, it can now happen that the bag has an undesired free space between the filler and the filler after it has been closed by the transverse weld seam. This means that the bags are not filled to the brim, which has disadvantages in particular when handling the bags further.
  • EP 420 821 A discloses a process for producing a vacuum pack for free-flowing products, in particular ground coffee.
  • the object of the present invention is to further develop the generic method in such a way that it is ensured that all bags are automatically tight and bulky, i.e. can be filled without unwanted dead volume.
  • This invention is based on the knowledge that the pouring properties of the filling material do not change abruptly. If it is determined by means of the measuring sensor designed as a sensor or optical measuring sensor that the bulk volume of the filling material has changed due to a change in the bulk density, then this measuring signal is passed on to a central unit, from where the slide and feed rollers of the device which prefers the tubular film web are controlled in such a way that the intermittent take-off length of the tubular film web sections formed is adapted to the respective filling level of the filling material in the sack. This means that the tubular film section forming the sack, which is already provided with the bottom weld seam and is fed to the filling device, is longer or shorter, depending on the bulk height of the filling material.
  • a tubular film section a few centimeters long is created, which can be collected separately and sent for recycling.
  • a corner weld is also provided (cf. EP-A-0 021 463), it must be taken into account here that the corners of the opening edge of the leading one are not at the same time Bag and the corners on the bottom weld seam of the subsequent bag section can be attached with a tool, as is easily possible with a tubular film web with scattering pressure is. Therefore, in accordance with this development of the method, the corner weld on the opening edge of the bag section is carried out simultaneously with the separating cut and the corner weld on the bottom seam is carried out simultaneously with the formation of the transverse weld seam. This requires a separate tool for corner welding on the edge of the opening and corner welding on the bottom seam.
  • corner welding seams can also be formed together with the second transverse welding seam by means of the separate corner welding tools, the distance between the corner welding tools then being able to be adjusted manually or automatically.
  • a frame 1 has side walls 2 and 3, which are indicated in FIG. 2. Both side walls 2, 3 are connected to each other by a crossbar 4.
  • This cross-member 4 carries approximately in the middle a downwardly projecting fixed axis 21, on which a swivel arm 5 is mounted near the cross member 4, which via a pressure-piston-cylinder unit 6, the cylinder of which is held by a support piece, in one of two possible end positions can be moved.
  • pivot arm 5 designed as an angle lever carries a molded part 5 'at its free end and is provided with a locking roller 7 in its angular region.
  • the function of these parts is discussed further below in the description.
  • a further vertical axis 8 is fastened to the cross member 4, which carries a four-armed turntable 9 below the swivel arm 5, which can be rotated by a motor 11 at intervals of 90 ° by a toothed belt 10.
  • the direction of rotation of the turntable is indicated by an arrow A in FIG.
  • Fig. 2 From Fig. 2 it can be seen that the freely cantilevered arms 9a of the turntable 9 forming a hub, as it were, carry fittings 12, each of which has two upwardly projecting pins 13.
  • a lever 14 is mounted rotatably about each pin 13 and is designed as a gripper 15 at its free end. Each of these grippers 15 rests against the counter surface 17 under the force of the springs 16, each shaped piece being provided with two counter surfaces 17.
  • the mutually facing levers 14 of two adjacent arms 9a are functionally connected to one another via a link 18 in such a way that the two associated grippers 15 open or close simultaneously, for example by a sack 19 to be able to grasp and hold.
  • the grippers 15 are opened by the wedge-shaped or curved cam surfaces of the molded part 5 'of the support arm 5 of the fitting 12 apart so that the grippers 15 pivot about the pin 13 and detach from the associated counter surfaces 17. At the same time, the grippers 15 of adjacent shaped pieces are released via the handlebars 18. In the position shown in FIG. 2, the gripper units 15 facing the upper and the right-hand edge of the drawing would thus be released when the pressure medium-piston-cylinder unit 6 is actuated.
  • the securing roller 7 mounted in the angular region of the swivel arm 5 runs into a guide groove 22 of a locking plate 23 when the swivel arm is pivoted to open the grippers.
  • This locking plate 23 is firmly connected to the turntable 9 by means of screw bolts 24, so that it is prevented from rotating by the securing roller 7 of the swivel arm 5, for as long as the molded part 5 'is between the rollers 20 of a molded part 12.
  • a hose 26 runs from a roll 25 from above into an inlet station 27.
  • This inlet station 27 is connected in a stationary manner to the frame-shaped frame 1 and can be seen in more detail in FIG. 3.
  • 3 shows the central axis 8 of the cooling carousel and a part of the turntable 9.
  • a hose section 19 provided with a bottom seam is clamped by the grippers 15 and the counter surfaces 17 of the turntable 9, but which is initially still connected to the tubular web 26.
  • the carrier 30 also has a knife groove 32 and a welding jaw 33.
  • a knife 34 dips into the knife groove 32 to separate the bag 19 from the tubular web 26, while a second welding jaw 35 interacts with the welding jaw 33 in order to provide the leading end of the tubular web 26 with a transverse weld seam.
  • the tubular web 26 When printing the tubular web 26 in format printing, it is important that the tube sections are not cut into the print when the tube sections are formed. Therefore, the preference of the tubular web is clocked by means of a print mark arranged at the opening edge of the respective sack.
  • the length of the bag section is changed in accordance with the measurement signal recorded by the sensor by cutting a more or less long strip between the opening edge of the bag section and the bottom weld seam of the following bag section.
  • These cut away tubular sections can be collected and sent for recycling.
  • the knife 34 When the separating cut is formed at the opening edge, the knife 34 is placed on the tubular web 26 without the welding jaw 33. After corresponding preference around the intermediate section to be cut away, the knife 34 is placed again on the tubular web 26, but this time together with the welding jaw 33. The separating cut of the intermediate section and the transverse weld seam of the subsequent bag section are therefore carried out or formed at the same time.
  • a further clamping device is provided above the welding jaws 33 and 35, which clamps the tubular web 26.
  • These consists of a pivoting lever 39 which is provided with a clamping strip 38 and which can be moved via a pressure medium-piston-cylinder unit 40.
  • An arm carrying a roller 41 is fixedly connected to the pivot lever 39, the roller 41 being at a distance from a guide piece 43 in the clamping position of the pivot lever 39.
  • This guide piece 43 is connected to a lever 44 which is held against a stop 46 via a spring 45.
  • the pivot point of the lever 44 lies on the axis of the preferred roller 47. It has a downward-facing shoulder which is designed as a counter-holder 48 to the terminal strip 38.
  • the pressure medium-piston-cylinder units 37 and 40 are first actuated after the formation of a bottom seam and a separation cut, and as a result the coupling rods 28, 36 and the lever 39 are pivoted away.
  • the roller 41 comes into contact with the cam surface of the guide piece 43.
  • This causes the counter-holder 48 to pivot in the direction of the arrow C, which on the one hand releases the freely hanging end of the web 26 from the welding jaw 33 and on the other hand deflects it. This deflection ensures that the web does not collide with the carrier 30 when it is advanced by a sack length by the preferred rollers 47 and 51 at the next cycle.
  • the preferred rollers are provided with annular grooves 49, 50, into which stripping fingers 52 and 53 engage. Of these fingers, the fingers 52 are held in place on the frame and the fingers 53 are attached to the counter-holder 48 as wiping rakes.
