Definitions

  • the invention relates to a method for strapping a packaged product with a strapping band, the band being removed from a band supply by a drive and then loosely wrapped around the packaged product until the end of the band is picked up and held in a connecting station, whereupon the band is pulled back and pretensioned and the tape end and the tape are connected in the prestressed state in the connection station.
  • Various methods and machines are known for strapping packaged goods with one or more strapping tapes. This is to stretch the strapping around the packaged goods, connect the end of the strap to the strap, and separate the strap from the strap stock.
  • it is known to allow the strapping process to take place without manual intervention (BE 20 624 ... application 1247/84 ).
  • the packaged goods are placed on a base provided with a yoke, in which a strap-pushing device is installed, with which the strapping band is pushed through the yoke, in which case the packaged goods are bypassed in a large loop until the strap end reaches a connecting station and there is held.
  • the strap pushing device is then switched to strap retraction, the strapping being placed around the packaged goods, tensioned and connected to the strap end and separated from the strap supply.
  • the tape feed at high speed into the yoke-shaped tape channel is not a particular problem and is relatively easy to achieve.
  • the tape can only be retracted so quickly that no tension peaks occur when the strap driving the tape is switched off that could either tear the strapping or damage the packaged goods. This means that the tape must be retracted at a lower speed, but this has an adverse effect on the strapping performance.
  • the invention comes in, which is based on the object of designing a method of the type described at the outset in such a way that the tape retraction takes place at high speed and tension peaks in the strapping tape are nevertheless avoided when the belt slide drive is switched off.
  • This object is achieved according to the invention in that the retraction of the strapping is carried out in two sections, of which first one section until the strapping lies loosely against the packaged goods at a first, greater speed and then the further section until the tensioning Band is carried out to the desired tension at a second smaller speed, being for the transition from the a tape transport interruption is formed first in the second speed.
  • the invention also includes a machine for carrying out the method according to the invention, with which the method can be carried out optimally.
  • a secondary belt drive is arranged between the main belt drive and the connection station, which has a higher belt speed than the belt speed of the main belt drive during the belt retraction until the strapping band lies loosely against the packaged goods.
  • the machine shown in FIGS. 1 and 2 shows two phases of an automatic strapping of a packaged product with one Strapping.
  • the machine has a base with a yoke-shaped band channel 2 arranged thereon.
  • a container 4 for receiving a supply of a strapping.
  • the strapping 5 can be introduced into the container 4 with a strap feed 6.
  • the strapping 5 can be pushed back and forth by a reversible belt slide drive 7.
  • the belt slide drive 7 has a main belt drive 11 designed as a force-fitting pair of rollers and a secondary belt drive 12 designed as a pair of rollers.
  • the main belt drive 11 and the secondary belt drive 12 are jointly operated by a motor, e.g. an electric motor 13, as will be shown in more detail with reference to FIG. 3.
  • Fig. 2 the strapping machine is shown when strapping the packaged goods 8.
  • the band slide drive 7 is reversed to retract the band.
  • the strapping band is now returned to the container 4, the band detaching from the band channel 2 and wrapping lightly around the packaged goods 8, as can be seen in FIG. 2.
  • the strapping process should also be carried out at the highest possible speed.
  • the tape advance in Bardkanal 2 is carried out at high speed.
  • the main tape drive When the end of the tape arrives in the connecting station 10, the main tape drive is uncoupled. Depending on the size of the moving masses of the main belt drive 11, it runs somewhat further after uncoupling and can form a loose belt loop 14. Since the moving masses are relatively small, the band loop 14 is also relatively small.
  • the main belt drive 11 After uncoupling the main belt drive 11, it is reversed for the belt retraction. The retreat is carried out at great speed.
  • the main belt drive 11 also drives the secondary belt drive 12, namely its pair of rollers is driven at a greater speed than the pair of rollers of the main belt drive 11. As a result, less belt length is returned to the container 4 than is supplied by the secondary belt drive 12.
  • a collecting magazine 16 is provided in the interior 3 of the base 1 for receiving the tape reserve. If, for any reason, the band reserve 15 would fill up the collecting magazine, a fill level indicator 17 is provided, which provides a signal for switching off the machine.
  • the formation of the band reserve 15 continues until the strapping band 5 easily wraps around the packaged goods 8. Then the main belt drive 11 is switched to a second, lower belt retraction speed.
  • the tape reserve 15 is first used up at this speed, ie the tape reserve 15 is pushed back into the container 4. As soon as the band reserve 15 is used up, the strapping band wrapped around the packaged goods 8 withdrawn and stretched as far as this corresponds to the setting of an electromagnetic clutch, which is arranged in the drive branch for the second lower speed.
  • FIG. 3 the belt slide drive of the machine shown in Figs. 1 and 2 is shown schematically.
  • the main belt drive and the secondary belt drive are designated by the reference numerals 11 and 12 as in FIGS. 1 and 2.
  • the two drives 11, 12 and the associated drive parts are mounted in a wall 18 of the base 1.
  • the connection station 10 is also fastened in this wall, with which the end of the strapping process connects the end of the band to the band, in some cases welds it, and the band from the band supply is separated.
  • the motor 13 drives via an enveloping drive 19 which consists of two wheels 20, 21 and an enveloping member 22, e.g. a toothed belt, there is a distribution shaft 25 which drives a first clutch shaft 27 via a further cladding drive 26 and a main clutch shaft 30 via a gear transmission 28.
  • a second clutch shaft 29 is driven by the first clutch shaft 27 via a gear train 31 with a gear ratio of 1: 1.
  • Each clutch shaft 27, 29 has an electromagnetic clutch 32, 34, with which the clutch shafts 27 or 29 can be coupled to the cladding drive 26.
  • the coupling shafts 27, 29 drive a pinion 36 in opposite directions of rotation via a gear 35, on which a roller 40 of a pair of rollers 40, 41 (see FIGS.
  • the roller 40 is a wheel of an enveloping drive 37, the enveloping member 38 of which drives a wheel 39 on the main coupling shaft 30.
  • the roller 41 is an adjustable, e.g. eccentric roller with which the tension of the enveloping member 38 is adjusted.
  • the strapping 5 is, see FIGS. 1 and 2, non-positively guided over the pair of rollers 40, 41, wherein it lies on the roller 40 on the sleeve member 38 and is pressed on the roller 41 by the sleeve member 38 onto the circumference of the roller 41.
  • the frictional connection that can be achieved in this way can transmit a multiple of the greatest tensioning force of the strapping 5.
  • the wheel 39 of the enveloping drive 37 is connected to a wheel 43 of an enveloping drive 42, the further wheel 44 of which is connected to a roller 50 of a further pair of rollers 50, 51 of the auxiliary belt drive 12.
  • the non-driven roller 51 of the auxiliary belt drive 12 is in an eccentric sleeve 50 rotatably mounted in such a way that the two rollers 50, 51 can form clamping rollers for the intermediate strapping 5 via the tape retraction, but not during the tape advance.
  • An electromagnetic main clutch 52 is mounted on the main clutch shaft 30, the armature 53 of which is slidably mounted on a pinion 54 connected to the wheel 39 of the enveloping drive 37.
  • the tape placed around the packaged goods 8 is free of tension and stands still.
  • the auxiliary belt drive 12 is set in such a way that it runs in this standstill phase but does not exert any force on the belt.
  • the tape reserve 15 is used up, the tape is brought up to the voltage set on the main coupling 52 and the connection station 10 is activated.
  • the switching of the main clutch 52 and the clutches 27, 29 thus takes place in a standstill phase in which the belt is not additionally stressed. Even if the time interval for switching the clutches 27, 29, 52 is very short, the distance traveled by the belt is approximately 0.5 m at the first, greater speed of about 5 m / s used. If the tape reserve 15 were missing, considerable additional stresses of the tape with the known disadvantages could occur during the switching time.
