Definitions

  • the invention relates to a device for the flying change of a first drum with a roll of plastic tape to a second drum with a roll of the same plastic tape, in which in addition to the two drums, a cutting and gluing device and control means for actuating the various drives are provided.
  • the object of the invention is therefore to design a device for the flying change of a first drum with a roll of plastic tape to a second drum, so that the waste of packs in the pack manufacturing machine is reduced, although the manufacturing machine continues continuously during the drum change or roll change becomes.
  • a cutting and gluing device and control means for actuating the various drives are provided in that deflection, guide and pressure rollers are arranged symmetrically to a center line are which are perpendicular to Connection line of the axes of the two windings runs that one pressure roller is adjustable relative to the other and that the adjustment drive for this can be controlled by a switch which is actuated as a function of the position of a winding scanning roller.
  • the changeover device thus works from a first drum with a first reel to a second drum with a second reel, which are arranged at a distance from one another, a center line being intended perpendicular to the connecting line between the reel axes, which are identical to the reel axes, with respect to which some parts of the device are arranged symmetrically, for example deflection rollers, guide rollers and pressure rollers. While it is known per se to guide tapes, such as the plastic tape processed here, over deflection and guide rollers, according to the invention a pressure roller is also provided symmetrically to the other side, the roller opposite the adjusted pressure roller always serving as a counter roller.
  • the two plastic tapes are pressed on a control command, which is given in a manner to be described just at the moment when the first winding has almost ended and the beginning of the second winding is threaded over that of the two pressure rollers, over which not exactly the tape runs off the work roll, namely the first roll that has just ended.
  • the second, full roll which represents the replacement roll, so to speak
  • a piece over a length of, for example, 1 to 8 cm, preferably 2 to 6 and particularly preferably 4 cm, an adhesive layer on both flat tops carrying adhesive tape is applied. So if you look at the tape running from the work roll, which is gradually approaching its end of supply, during operation, you can see how this tape over one of the two pressure rollers, which is preferably driven, without contacting the other, second, non-driven, stationary drive roller runs. Between the facing surface points of the two drives roll is generally a distance during operation, preferably from 3 to 10 mm, particularly preferably from 6mm. The start of the tape of the replacement reel begins on the opposite second drive roller and lies, so to speak, ready for use on this second drive roller.
  • the above-mentioned winding scanning roller scans, as its name suggests, the winding around the circumference and thus changes its position in the course of operation until the above-mentioned switch is actuated when the first winding has almost ended, which, among other things, acts on the adjustment drive for the pressure roller .
  • the stationary pressure roller with the adhesive tape is pressed onto the opposite, rotating pressure roller, so that the beginning of the tape of the replacement roll is glued to the end of the tape of the work roll.
  • the adhesive device with the pressure rollers also has a cutting device in such a way that, at the moment of pressing on the replacement pressure roller on the working side, the continuous tape is at a short distance from the tape point which is just touching between the two Pressure rollers is located, is cut against the transport direction of the belt.
  • This distance between the mentioned point between the pressure rollers on the one hand and the cutting point in the direction opposite to the running direction of the belt on the other hand is 2 to 15 cm, preferably 30 to 100 mm and particularly preferably 70 mm.
  • this pulse triggered by the switch also commands the packaging machine, e.g. eject a certain group of packs as rejects because it can be assumed that the adhesive strip is in this group of packs.
  • the packaging machine e.g. eject a certain group of packs as rejects because it can be assumed that the adhesive strip is in this group of packs.
  • the packaging machine e.g. eject a certain group of packs as rejects because it can be assumed that the adhesive strip is in this group of packs.
  • the packaging machine e.g. eject a certain group of packs as rejects because it can be assumed that the adhesive strip is in this group of packs.
  • the packaging machine e.g. eject a certain group of packs as rejects because it can be assumed that the adhesive strip is in this group of packs.
  • the group of packs which are ejected as rejects can be exactly determined in the running production line because the Production speed is specified and thus the distance between the adhesive piece arriving with the plastic tape to the pack, to which the plastic tape is applied with this adhesive piece, is precisely determined.
  • the pack-making machine can therefore continue to run, continuously feed an edge protection strip made of plastic, even though a first storage drum with a plastic band runs empty after a long period of operation and is replaced by a second replacement drum.
  • the winding scanning roller which can be guided along the circumference of the winding, is rotatably attached to a scanning arm arranged symmetrically to the center line with respect to another scanning arm, and the respective scanning arm is attached to an articulated block which can be pivoted about an axis parallel to the winding axis and carries a switch pan for operating the switch.
  • the machine can be particularly robust and reliable in this way because a scanning arm with roller and control is provided for each drum on the respective side of the center line mentioned. The control is carried out by the angular position of the scanning arm, which, for example, is horizontal at the start when the winding is full and an angle of e.g. Has passed through 45 ° until the end position is reached.
  • the hinge block has thus also pivoted about 45 ° about the axis, so that the switching pan carried by it comes into the area of the switch after actuation of the elbow and actuates it. It is particularly advantageous if the switching socket is adjustable relative to the joint block, because in this way an adjustment to the individual drum sizes can be carried out.
  • the hub of the drums, the axis of the joint blocks, the switch and the adhesive device are attached to a main plate.
  • these parts are arranged symmetrically to the center line mentioned and are therefore always present in pairs.
  • an arrangement is provided on a main plate, which results in a good manufacturing possibility and also better handling; in particular if, according to the invention, the main plate can be pivoted relative to the packaging machine. If the staff wishes to carry out maintenance or repair during operation or even during downtimes, then the main plate can be swiveled up easily from the frame of the machine without dismantling the device for the flying change according to the invention, and the parts installed behind this plate are immediately accessible.
  • At least one deflection roller is designed as a dancer roller.
  • the transverse sealing through the hose in the packaging production machine results in an intermittent operation, which has the consequence that the plastic band is also intermittently drawn from the supply into the production machine.
  • the dancer role can be used according to the invention to balance between continuous and intermittent.
  • a brake designed as a V-shaped steel bracket is connected to the arm of the dancer roll and can be brought into engagement with a side plate of the drum.
  • a V-shaped brake is not only easy and inexpensive to manufacture, but it can also be easily.
  • angled double arm are attached at one end, while the dancer roll is rotatably arranged at the opposite end of the double arm, while a rotating bracket is in the middle where the two levers come together.
  • the V-bracket follows the movement of the dancer roll in the manner described above.
  • This design and arrangement of the brake is advantageous because the side plate of the drum does not change during operation. The diameter of the disc remains the same despite the rotation of the drum and despite the reduction in the number of wraps on the drum. With one and the same position of the dancer roll and thus also the brake, the braking effect on the drum always remains the same.
  • a cut-off protection is fitted behind the adhesive device. So if for any reason the tensile stress in the plastic belt drops too much on the outlet side, this fuse switches off the belt drive in question, so that malfunctions are advantageously avoided.
  • This switch-off protection can be designed according to the invention in a particularly advantageous manner so that a roller provided with a certain weight is arranged between two deflection rollers in such a way that this roller is carried by the continuous plastic belt. If the tension in the plastic belt drops very sharply or the belt even tears, then this roller falls down and actuates a switch to interrupt a drive circuit.
  • This switch and also the switch mentioned above can be microswitches, preferably proximity switches.
  • An approximation can be provided or canceled via a switching flag, as a result of which one or the other switching state of the switch is reached. If the mentioned roller can be rotated about an axis via a pivotable arm, then its path of rotation is a circle.
  • the switching flag connected to this roller as a switch-off safeguard can, according to the invention, also be embodied in an arc shape in such a way that a switching flag with a partial cylinder surface is provided, which is used for switching on device or switching off the proximity switch concerned.
  • the roller can dance during operation with a certain amplitude on the plastic tape running under the roller and with it the elongated switching flag in the direction of movement, so that the proximity switch really only switches off when the roller acting as a switch-off protection has passed through a larger amplitude.
  • FIG. 1 On a main plate 1 with its center line m, the hub 2 of a first drum (not shown) with the first winding 3 is symmetrical on the left and the differently designed hub 2 'of the second winding 3' is symmetrical on the right. by means of the axes 4, 4 'arranged, which protrude perpendicularly from the plane of the paper and thus also perpendicularly from the main plate 1.

  • the second plastic belt 13 'initially held in the waiting position runs in an analogous manner from the winding 3', loops around the deflection roller 15 'designed as a dancer roller, then the deflection roller 16' and then runs symmetrically to the belt 13 with respect to the center line m on the cutting device 9 ' over the guide roller 8 'to adhere to the pressure roller 7' held at a distance from the pressure roller 7 '.
  • the circumference of the respective roll 3 is scanned by a roll scanning roller 26 on one or 26 'on the opposite side.
  • the winding scanning roller 26 is rotatably attached to a scanning arm 27 or 27 ', which is connected via clamping and screwing to the mentioned joint block 11 or 11'.

  • the deflection roller 15 at the end of the first lever 35 can run against a Z-shaped bracket 40 according to the illustration in FIG. 1, which ensures that the lever 35 about the pivot point 37 are not rotated further in the counterclockwise direction but are locked in the position shown in FIG. 1.
