Definitions

  • the invention relates to a machine for strapping packages with a strapping means, in particular a thermoplastic plastic band, with a strapping stock held on a drum and a strapping stock arranged between the strapping device and a strapping device for a storage amount of the strapping stock corresponding approximately to the strapping length, the strapping stock storing two Has groups of deflecting rollers, which are each arranged on a roller carrier, at least one of which is arranged so as to be movable with respect to the other to form the storage quantity under the action of a tensioning force, and the strapping means continuously alternately wraps around the roles of both groups of deflecting rollers.
  • a strapping means in particular a thermoplastic plastic band
  • Strapping machines with such strapping agent stores have proven themselves very well in practice.
  • the reason for the operating and maintenance personnel being annoying, however, is the relatively laborious, manual insertion of the strapping means, that is to say the respective structure of the strapping means store. It must be remembered that these handouts are to be carried out in the mostly cramped interior of the machine.
  • the invention has for its object to provide a machine of the kind outlined in the preamble of claim 1, in which the strapping agent storage device is particularly excellent in terms of simplified handling when introducing strapping agents.
  • each roller carrier has rollers arranged approximately axially parallel to the gap in one row, the rows of rollers being offset from one another in such a way that they comb in and through the gaps of the other row can dip them into a strapping insertion position.
  • the moveable roller carrier with the rollers it supports could only touch the move their roller carriers or their rollers.
  • the movable roller carrier it is now possible for the movable roller carrier to be movable out relative to the other, possibly also movable or machine-fixed.
  • the encounter takes place like the intermeshing and reaching through of two combs, so that the row of rollers of one roller carrier can move from its strapping-storage position on one side of the other roller carrier beyond this into a strap insertion position.
  • This strapping means insertion position is now characterized in that there is a space between the rollers of the two roller carriers, through which the strapping means can be passed smoothly and without any obstructions along a straight line.
  • the movable roller carrier is then transferred from its strapping insertion position back to the strapping storage position - this can be done manually or by means of springs or in a hanging arrangement due to the weight of this roller carrier - the rollers put on the strapping material, take it, pass it through the gaps in the row of rolls of the other roll carrier and thus form the strapping agent store.
  • the axes of the rollers of the two roller carriers can point away from them in opposite directions. This design allows a particularly simple structural design because the roller carriers themselves can be simple tabs or plates on which the roller axes are arranged overhung. While the roles meet on one level, one role carrier is present and the other role carrier is behind this level.
  • roller carriers lie in a common plane, in particular when they are designed in a tine-like manner and carry the respective rows of rollers at the ends of the tines to be pointed towards one another.
  • the movable roller carrier can also be temporarily locked according to a further advantageous embodiment in the strapping insertion position, so that both hands are available when inserting the strapping, although practically only one is now needed.
  • a device can now be provided which automatically or upon request transfers the strapping material store into the strapping means insertion position.
  • Automatic control is desirable, for example in the event of an interruption in the power supply or if one is exceeded selected machine downtime and on request, for example for maintenance purposes. It is particularly advantageous if, when the strapping supply has run out and / or when the strapping means is interrupted, the strapping means store can be controlled into the strapping means insertion position.
  • the strapping With this transfer or control into the strapping adjustment guide, the strapping is relieved of strain, in particular freed from its roller deflections. This is impossible with conventional strapping agent stores and leads e.g. after long interruptions when the band store is full, the strapping means are deformed plastically to form waves, which can lead to malfunctions in the strapping device. Such malfunctions can be avoided in the subject matter of the invention due to the design of the strapping material store.
  • a machine 10 for strapping packages 11 with a strapping means 12, in particular a thermoplastic, weldable plastic strap, comprises a machine frame 13 with a control cabinet 14, strapping channel 15, sealing unit 16, strapping agent conveyor 17, strapping agent supply 18 and strapping agent storage device 19
  • Fig. 1 machine shows the prior art, which also makes use of the embodiment of the invention.
  • a conventional strap storage 19 is shown. This comprises two groups 20 and 21 of rollers 22 and 23 which are rotatably received coaxially on roller carriers 24, 25.
  • the roller carriers are rod-like axes.
  • the upper roller carrier 24 is fixed to the machine, that is to say rigidly, while the lower roller carrier 25 is dancing can perform. The further he moves away from the roller carrier 24, the greater the storage quantity 26 of the strapping means 12, which is stored as a strapping agent supply 26 on a drum 27 which can be rotated about a drum axis 28.
  • FIG. 2 shows a standard strapping tool store, the upper roller carrier 24 of which is equipped with seven and the lower roller carrier 25 is equipped with six rollers. The tape must therefore be wrapped around a roll 13 times. It goes without saying that this is very tedious.
  • a first roller carrier 24 is attached to the machine. He carries a row 20 of rollers 22, but not coaxially, but with axially parallel axes and with gaps 29 between two rollers.
  • the second roller carrier 25 is constructed similarly. Its rollers 23 are also including gaps 30 in an axially parallel orientation in ranked group 21 held. However, this second roller carrier 25 can be moved relative to the other roller carrier 24.
  • the movable roller carrier 25 is guided in the embodiment with a guide sleeve 31 on mutually parallel machine-fixed guide rods 32 in a slide-like manner. Such guidance is not necessary. A pivotal movement or the like, which is supported by a parallelogram arm, for example. can be executed. Since the roller carrier 25 can be displaced in the horizontal direction in the exemplary embodiment, it is under the tensioning force of tension springs 33. In deviation from this, the tensioning force could also be applied with the aid of pressure medium cylinders.
  • FIGS. 3 and 4 illustrate the strap storage 19 in its storage position. If strapping material in the amount required for the relevant package 11 is guided from the device 17 to the strapping channel 15 and around the package, the strapping material reservoir 19 empties in accordance with the required amount of strapping material. After the sealing process, the strapping material fills memory 19 again in that, with reference to FIGS. 3 and 4, the movable roller carrier 25 is moved to the left as a result of the clamping force. Usually, a strapping material store is not completely emptied during a work cycle, so that the movable roller carrier 25 at most comes into the vicinity of the other roller carrier 24.
  • roller carrier 25 is to be moved towards and beyond the roller carrier 24.
  • the rollers are arranged essentially in one plane - at least during the meeting of the two rows of roller groups 20 and 21.
  • the rollers 23 of the roller carrier 25 can consequently pass through gaps 29 between the rollers 22 of the roller carrier 24 until the roller carrier 25 has reached the opposite side of the roller carrier 24 with respect to its storage position (FIGS. 5 and 6).
  • a space 34 is formed between the rows of rollers 20 and 21 through which the Drum 18 stripped means 12 can be pulled completely straight through in a simple manner. It only has to be guided around the lowermost roller 36 and an uppermost roller 22 of the roller carrier 24 and possibly around a further deflecting roller 35 before it is transferred to the conveyor device 17.
  • the roller carrier 25 is preferably releasably locked after the strap 12 has been inserted in the manner described, this locking is released, so that the roller carrier 25 is again in its strapping means.
  • Storage position can move to the left. His rollers 23 mesh with the rollers 22 of the other roller carrier 24 and take the strapping means 12 into the storage position according to FIGS. 3 and 4.
  • Fig. 5 in particular it can be seen that the strap is hardly used in the strapping insertion position shown there. Therefore it makes sense to e.g. to relieve the load during longer machine downtimes or in the event of operational malfunctions by moving the roller carrier 25 into this position or letting it move automatically. In addition, it can also be ensured that the strapping means 12 is relieved of longitudinal forces, so that the three deflections which can still be seen in FIG. 5 are completely relieved of tensile force.
