Definitions

  • the invention relates to a method for producing, filling and closing sacks from a tubular film web made of thermoplastic, preferably provided with side gussets and printed in format printing, in which the respective leading end of the tubular film web is provided with a transverse weld seam and a section forming an open sack of the tubular film web is separated and in which the sack is then filled and the open side of the sack is closed by a cross weld.
  • 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.
  • open sacks removed its open side taut and closed in a specially provided trimming 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 preferential rollers, through which the front end of the tubular film web, each provided with a cross-weld seam, is pushed in a vertical direction, freely hanging, intermittently by one bag or sack length between welding jaws of a welding device that perform 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 that is 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 transverse weld seam is then formed at the end of the tubular path, while the cooling carousel rotates intermittently through an angle of 90 ° and in this position pauses for a long time until another sack with a cross weld is inserted into the next station. This is repeated in a four-arm cooling carousel until the first station has rotated 270 ° in three cycles.
  • 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.
  • the object of the present invention is to further develop the generic method in such a way that it is ensured that all sacks can be filled tightly and bulky, ie without undesired dead volume.
  • the object is achieved on the basis of a generic method in that the length of the tubular film web sections formed is already varied in accordance with the filling height of the bag, that replication of the transverse weld seam closing the bag, the tubular film web is cyclically advanced up to a printing mark that the section forming the bag is separated by means of a separating cut without simultaneous formation of the transverse weld seam closing the subsequent tubular film section, that the subsequent tubular film web is again pulled forward by a comparatively short adjustable length, that optionally the advanced section of the tubular film web is separated again and that the transverse weld seam closing the subsequent tubular section is formed.
  • This invention is based on the knowledge that the pouring properties of the filling material do not change abruptly.
  • the operator will vary the length of the tubular film web sections formed and the respective filling level of the filling material by adjusting the slide and feed rollers of the device that prefers the tubular film web adjusted in the sack. According to the method according to the invention, it is now advantageously prevented that the tubular film web is severed at a printed point by varying the length of the tubular film web section formed in each case.
  • tubular film web is always pulled up to a print mark at the opening edge of the sack to be cut, that it is then cut off and that the bottom weld seam of the following section then varies according to the length of the section to be formed, depending on the setting due to the fill level by the operator becomes.
  • a tubular film web section a few centimeters long is created, which can be collected separately and sent for recycling.
  • this tubular film section especially if it is only a very small width, remain as a protrusion on the sack.
  • the previously described intermediate preference of the tubular film web can be set to zero after the sack section has been separated in the event that the bulk material reaches its minimum expected bulk density and thus a maximum bulk height. This is the case, for example, in the completely dry state of a granulate to be filled. In this case, when the leading sack section is cut off, the transverse weld seam can be formed at the following sack section at the same time, since the maximum available length of the tubular film web section is used here.
  • corner welds are simultaneously applied when cutting and attaching the transverse weld seams, as is known, for example, from EP-A 00 21 463, it must be taken into account that the corners of the opening edge of the leading bag and the corners on the bottom weld seam of the subsequent bag section are not at the same time here can be attached with a tool, as would be easily possible, for example, with a tubular film web with scattering pressure. Therefore, according to a further advantageous embodiment of the present invention, the corner welding at the opening edge of the bag section and at the bottom seam in each case by means of a separate corner welding tool. Depending on the length of the intermediate section, the section can then be readjusted manually or automatically between the separate corner welding tools. In an advantageous manner, all corner weld seams can be formed simultaneously with the transverse weld seam closing the subsequent hose section.
  • the corner weld on the opening edge of the bag section can be carried out simultaneously with the separating cut and the corner weld on the bottom seam can be carried out simultaneously with the formation of the transverse weld seam.
  • the duration of the process sequence is comparatively longer, since with simultaneous corner welding at the opening edge of the sack section with the implementation of the separating cut, it is no longer the time for cutting the web but the welding time for the corner welding that determines the speed. In the event that the intermediate preference is set to zero, both tools are fed to the tubular film web at the same time.
  • 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 in each case via a pressure medium-piston-cylinder unit 6, the cylinder of which is held by a support piece can be moved from two possible end positions.
  • 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 to be able to grip and hold a bag 19.
  • the grippers 15 are opened by the wedge-shaped or curved cam surfaces of the molded part 5 'of the support arm 5. If the support arm 5 is pivoted by extending the piston rod of the pressure medium-piston-cylinder unit 6, the molded part 5' presses the pressure rollers 20 connected to the levers 14 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 situation shown in Fig. 2 would therefore when the pressure-piston-cylinder unit 6 is actuated, the gripper units 15 facing the upper and the right-hand edge of the drawing are released.
  • the securing roller 7 mounted in the angular region of the pivot arm 5 runs into a guide groove 22 of a locking plate 23 when the pivot 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 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 is initially still connected to the hose track 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 is printed in format printing. In this case, it is important that the hose sections are not formed is cut into the print. 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 corresponding operator now changes the length of the bag section by cutting away 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 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.
  • This 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 causes the freely hanging one End of the web 26 is detached from the welding jaw 33 and deflected to the other. 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 on 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.
