Definitions

  • the invention relates to a machine for strapping packages according to the preamble of claim 1.
  • Such a machine which has a strapping tunnel and operates automatically at the push of a button, is intended for the continuous strapping of packs fed one after the other, which can be packages or objects to be bundled, for example.
  • a plastic tape pulled off a supply roll which is stretched around the package, cut off and welded to one another at its ends, is preferably used as the strapping means.
  • the strapping means can also have a cross-sectional shape other than a band or be a cord.
  • the machine is particularly intended for such a strapping means which, due to insufficient rigidity, has to be pulled around the package instead of being pushed around.
  • a machine of this type known from DE-OS 25 18211 has a program circuit for reversing the rotor, referred to as the driver terminal, for the strapping means. It can be seen from this note that the stopping of the runner and the actuations required for releasing the beginning of the strapping means which is wrapped around the package and for detecting the new beginning are controlled by means of a circuit. To do this, it is necessary to stop and accelerate the belt carrying the runner together with the runner after each revolution. However, each acceleration takes more time, the more mass has to be accelerated.
  • Another disadvantage of the known machine is the retraction force limited by the storage device with the storage capacity when the strapping means is tightened around the package. This is due to the fact that the accumulator is a continuous accumulator arranged between the supply roll and the bypass area, the retraction force of which must be less than the tensile force of the rotor.
  • a strapping machine is known from DE-PS 913 637, which, however, does not belong to the category of tunnel machines, so that the packages to be strapped cannot be pushed through one after the other. It is therefore necessary to take each strapped package back to the side from which it was fed, so that efficient handling is difficult.
  • This known machine has a chain which is constantly set in drive and has lugs as drivers, to which a carriage guided by rollers on a guideway can be coupled and uncoupled. By means of an eyelet-like device, the trolley pulls a wire as a strapping means around the previously inserted package. Due to the type of strapping agent supply, this known machine is not suitable for processing tape. The circulating chain and the carriage running on rollers are known to cause a considerable amount of noise.
  • the drivers on the chain require a special design of the chain that is subject to wear and not only cause additional noise when the car is engaged, but also jerky loads on all moving parts.
  • a preparatory loop formation is not possible with this machine, so that the wrapping process can only take place after the package has been inserted and held in place. As a result, no noteworthy short working cycles are possible with this known machine.
  • the invention has for its object to provide a machine of the type mentioned, in which only a small mass is accelerated to achieve a high cycle speed in each work cycle.
  • the tensioning force when tensioning the strapping means should be greater than the tensile force of the runner.
  • the coupling device is arranged exclusively on the rotor, no means, such as for example drivers, are required on the belt, so that commercially available belts are suitable for this purpose. No guidance is required along the bypass path for the runner carried freely by the belt.
  • Fig. 1 the individual assemblies of the machine intended for strapping packages are shown in a functional context.
  • the band 20 intended for strapping is drawn off from a supply roll 22 by means of a band feed drive 21 and fed to a band store 23 which has two mutually opposite sets of rolls 24 and 25, which are preloaded by spring force in opposite directions.
  • Each of the two roller sets 24 and 25 has a plurality of rollers which are freely rotatable on an axis.
  • the roles of the two sets of roles are alternately wrapped around the belt 20.
  • the beginning of the band 20 is guided by a runner 34 around the four band rolls 30 to 33 along the orbit 28 until it reaches the closure device 29 again.
  • the runner 34 can be coupled and uncoupled to an endless belt 35, which wraps around four belt deflection rollers 36, 37, 38 and 39, which are each located next to the belt rollers 30 to 33, although it is not necessary that they be directly coaxial are arranged to these.
  • a belt drive 40 which is drive-connected to the first belt deflection roller 36 via a belt transmission 41, serves for the continuous drive of the belt 35.
  • An actuating magnet 42 is connected by means of transmission members 43 to the band rollers 30 to 33 in order to pivot it away from the plane of the band, so that the band 20 for releasing the package, not shown, which is located within the orbit 28, is released.
  • the transmission links 43 can have, for example, a linkage or cables.
  • a drive 44 is used to actuate the closure device 29, by means of which a coupling and uncoupling device (not shown in FIG. 1) for the rotor 34 is also actuated. Furthermore, the drive 44 also serves to actuate a belt clamp with which the runner 34 grips the belt 20.
  • a first switch 45 in the vicinity of the closure device 29 signals when the rotor 34 is in the closed position.
  • a second switch 46 connected to the transmission elements 43 serves for the time-delayed release of a further work cycle.
  • a third switch 47 connected to the tape store 23 serves to reload the tape store by switching on the tape feed drive 21.
  • FIG. 2 shows a machine for strapping packages in the front view, which operates according to the basic scheme shown in FIG. 1.
  • 2 shows in particular that the machine has a table surface 50 on which the packages (not shown) intended for strapping can be pushed through the tunnel 51 one after the other.
  • the supply roll 22 is located on the side of the machine for easy replacement.
  • the strapping tunnel 51 is surrounded by a frame 53 which encloses the orbit 28. To symbolize the orbit 28, the belt 35 and the belt deflection rollers 36 to 39 are indicated as invisible edges.
  • the frame 53 Towards the center of the tunnel, the frame 53 has a slot (not visible) in the wrap plane in order to release the band 20 for tying the packages.
  • the rest position of the rotor 34 is in the closed position shown.
  • the unit 54 is connected to the drive 44.
  • the functions mentioned are explained in detail with reference to the following figures.
  • Figures 3 to 5 show the runner 34 coupled to the belt 35 in three views.
  • the beginning of the band 20 is clamped in a band clamp 55.
  • the movable jaw 56 of the band clamp 55 is mounted on an axis 57 and is biased in the clamping direction at the opposite end 56 'by means of a compression spring 58.
  • the runner 34 has guides 59 and 60 on both sides, which serve to guide the runner when positioning in the unit 54 according to FIG. 2.
  • a locking lever 61 is pivoted up in the coupled position in order to ensure the lateral position of the rotor 34 on the belt 35.
  • FIG. 4 shows the arrangement of a release lever 62 which is pivotable about an axis 63 and is loaded by means of a spring 64 in the position coupled to the belt 35.
  • a coupling lever 65 which is connected to the release lever 62 and which engages from below on the belt 35 running in the direction of arrow 66, is used for coupling to the belt 35.
  • the safety lever 61 is mounted on a second transverse pivot axis 67. It is taken along by a release pin 68 from the release lever 62 in such a way that it is pivoted counterclockwise about its axis 67 according to FIG. 4 when the release lever 62 is pivoted clockwise by an actuator, not shown. This means that it is pivoted downward when the runner 34 is uncoupled from the belt 35. This makes it possible for the runner 34 according to FIG. 3 to be moved to the left with the belt 35 running, by an amount which corresponds approximately to the free space 69 to the right. This freedom of movement in the uncoupled position is discussed in more detail in the explanation of the following figures.
  • the driving pin 68 is rigidly connected to the securing lever 61 and engages in a recess 70 in the release lever 62.
  • the housing of the rotor 34 is denoted by 71.
  • FIG. 5 shows the runner 34 approximately along a section line V-V according to FIG. 4. Only the band clamp 55 and the band 20 clamped therein are shown outside the section line mentioned.
  • the rotor can be removed from the belt 35 by actuating the release lever 62 and by pivoting it out. It is put on by actuating the release lever 62 and by pivoting the rotor.
  • FIGS. 6 to 9 show a device for uncoupling and coupling the rotor in different operating positions.
  • This device is a component of the unit 54 indicated in FIG. 2. Components already mentioned are the table surface 50, the belt 35 driven underneath and the rotor 34.
  • the runner 34 coupled to the running belt 35 approaches a braking lever 72 which can be pivoted about a pivot axis which is hidden in FIG. 6 and whose opposite end 72 'is biased in the direction of arrow 73 by a spring.
  • the various elements of the uncoupling and coupling device shown in FIG. 6 are in the ready position for stopping and uncoupling the arriving runner 34, which has already run into a lateral guide rail 74 which leads into the right guide 60 of the runner 34 according to FIG 3 intervenes.
  • the illustrated guide rail 74 is opposite a guide rail of the same length, not shown, which engages in the left guide 59 of the rotor 34.
  • a pawl 75 is embedded in the illustrated guide rail 74, over which the runner 34 is sliding according to FIG. 6.
  • the release lever 62 of the rotor 34 is still in the coupling position.
  • the braking lever 72 was pivoted counterclockwise against the spring force 73 by the impact of the rotor 34 about its pivot axis 77, as a result of which a rod 81, which was guided parallel to itself via two arms 79 and 80, was moved to the left via a driving pin 78.
  • the two arms 79 and 80 are pivotable about fixed pivot axes 82 and 83.
  • the right arm 80 is biased clockwise by a spring force 84 acting on it, so that the rod 81 is moved to the left against the spring force.
  • a recess 85 in the rod 81 cooperates with a pin 86 which is attached to an arm of a ratchet lever 87.
  • the pawl lever 87 was therefore rotated counterclockwise about a fixed axis 88 against a spring force 89 acting on it, since the pin 86 was displaced from the recess 85.
  • the rotary movement of the pawl lever 87 caused its pawl 90, which engages in a notch 91 of the uncoupling plunger 76 in the retired state, to release the uncoupling plunger 76, which in turn rose upwards under a spring force 92 (FIG.
  • the uncoupling plunger 76 is guided by stationary guides 93 and 94 and by further guides, not shown.
  • the brake lever 72 is on an intermediate lever 95 with its pivot axis 77 mounted, which is pivotable about a fixed axis 96 against a spring force 97.
  • the runner 34 uncoupled from the belt 35 has been pushed back against the direction of the pawl 75 by the braking force 72 against its direction of travel by the action of the spring force 73.
  • the braking lever 72 acts as a buffer by first stopping the rotor and pushing it back after it has been uncoupled. In this position, the runner 34 assumes a precisely defined position in relation to the unit 54 for transferring the carried tape and for detecting the new beginning of the tape.
  • the rod 81 also follows it under the action of the spring force 84.
  • the pawl lever 87 was also released, which can be checked with reference to FIGS. 6 and 7.
  • the pawl lever 87 is under the action of the spring force 89 again in the ready position to engage with its pawl 90 in the notch 91 when the uncoupling plunger 76 is retracted.
  • FIG. 9 now shows the operating position in which the runner 34 was coupled to the rotating belt 35 shortly before.
  • a reset lever 98 was pivoted counterclockwise by retracting a rod 99 about a fixed pivot axis 100.
  • the reset lever 98 with its nose 101 arranged at the end, has pivoted the intermediate lever 95 clockwise about its pivot axis 96 by rolling its nose 101 on a roller 102 arranged on the intermediate lever 95.
  • the brake lever 72 mounted on the intermediate lever 95 by means of the axis 77 was withdrawn from the path of the rotor 34.
  • the entire unit 54 is moved in a plurality of movement steps in order to move the runner 34 into the corresponding positions in order to deliver the reversed band start.
  • a full duty cycle takes only a fraction of a second, in which time all of the functions described above expire.
  • the rod 99 according to FIG. 9 is actuated by the drive 44 shown in FIGS. 1 and 2 via cam disks or crank gears, not shown.
  • the unit 54 together with the rotor 34 uncoupled and positioned from the belt 35 according to FIG. 8, is displaceably and pivotably mounted on a fixed round rod 107 by means of bearings 108 and 109 in the direction of the X axis.
  • the displacement in the X-axis is likewise carried out by the drive 44 according to FIGS. 1 and 2 by means of a sliding rod 110 which engages on the unit 54 and which, like the rod 99 according to FIG. 9, is actuated via cam disks or crank mechanisms which are not shown.
  • a plunger 120 can be actuated by means of an angle lever 121 via cam disks or crank mechanisms (not shown) from the drive 44 (FIGS. 1, 2) in order to clamp the jaw 56 of the rotor 34 (FIG. 3.12) by engaging the lever arm 56 ′ to open.
  • FIG. 11 shows a top view according to FIG. 10.

  • the belt 35 is only indicated to represent the relative position of the belt 20 drawn by the runner 34.
  • Such a closure device is generally known in specialist circles. It is only important for the invention that the runner 34, with its belt clamp 55, transfers the start of the bypassed belt in the first longitudinal position X1 and detects the new belt start in the second longitudinal position X2. For this purpose, the rotor 34 must not only be moved in the longitudinal direction X, but also in the transverse direction Y. For the longitudinal movement, the unit 54 can be displaced on the rod 107 by means of the displacement rod 110. The movement in the transverse direction Y takes place by pivoting the unit 54 around the guide rod 107 by means of a pivot rod 113, which engages on a bracket 114 via a joint 115.
  • the pivoting movement is transmitted from the bracket 114 to the unit 54 by means of a roller 116 rotatably mounted on the bracket 114, which acts on the one hand on the surface 54 'of the unit 54 and on the other hand on a guide plate 117 connected to the unit 54.
  • the swivel rod 113 has a trailing roller 118 at its end, which rolls on a cam disc 119, which is only indicated, which is connected to the drive 44 shown in FIGS. 1 and 2.
