Definitions

  • the invention relates to a method for dispensing labels from a label tape which has a carrier tape and adhesive labels adhering thereon, the carrier tape coming from a supply roll and leading to a carrier tape rewinder being placed in a loop around a label detaching edge and the label being passed to a label transfer device, e.g. a movable suction device, which transfers the detached label to the label, is donated. It also relates to a device for performing such a method.
  • a method is known in which a movable table is used, around which the carrier tape is placed approximately in the form of a rectangle.
  • this table is moved with its one end under a label transfer element, here in the form of a suction device, and the carrier tape is driven by a motor until a label on this table end is located exactly under the suction device.
  • This label is sucked up by the vacuum cleaner.
  • the table is then moved away again under the suction device, the carrier tape wrapped around the table shifting relative to it without changing the overall length of the rectangular loop.
  • the label held by the sucker is detached from the carrier tape and can then be transferred to the label.
  • the device known from DE-A1 3 233 546 also works in a comparable manner.
  • the carrier tape must be driven by an electric motor so that the label comes to rest exactly under the sucker. This is particularly difficult at higher labeling speeds, since due to the rectangular guiding of the carrier tape around the movable table, considerable flexing work is required if the carrier tape is driven by this electric motor. This can lead to difficulties when starting this electric motor, so that it stops if you try to increase the labeling speed too much.
  • the labeling accuracy (the electric motor is controlled by a label button) naturally also depends on the properties of the drive, e.g. the accuracy of a clutch.
  • high-precision switching drives e.g.
  • GB-A 1 369 568 is a labeling device in which the labels are detached by moving the carrier tape around a label detaching edge and then pressed directly onto the goods to be labeled by a transfer element, here in the form of a scraper.
  • a carrier tape rewinder is provided, which has a one-way clutch and therefore can only rewind the carrier tape, but prevents the same from unwinding.
  • the label peeling edge - together with the guide for the label tape - is pivoted about a horizontal axis of rotation by the label material being fed.
  • the carrier tape is moved by a linear drive with high specific power, typically a pneumatic working cylinder, during a first partial feed, the process is very fast.
  • a low-power but precise drive namely a rotating drive.
  • the labeling accuracy possible with such rotating drives is obtained, e.g. a stepper motor of normal dimensions can be used, which provides the required high torque and the required positioning accuracy at low speeds.
  • This rotating drive can then advantageously be used to quickly pull the label release edge back into its starting position by quickly pulling off the carrier tape.
  • the label detaching itself from the label carrier tape is taken over by a label transfer device.
  • the rotating drive can keep the carrier tape blocked - a separate brake may also be possible for this purpose, and conversely, during the rapid removal of the carrier tape, the label tape is blocked at a point in front of the label detaching edge.
  • the method is advantageously designed in such a way that during the first partial feed the feed movement is limited by a stop which can preferably be set to different label lengths.
  • the method according to the invention can advantageously be designed such that the linear drive is designed to act only in the feed direction, the label detaching edge then being retracted into its starting position only by pulling off the carrier tape.
  • the device according to the invention is designed such that the carrier tape deflected in the opposite direction is guided in a rotating drive which blocks the carrier tape when it is at a standstill and, during operation, ensures precise positioning, preferably at low speed, and a rapid pull-off movement of the in comparison to the positioning speed deflected carrier tape enables.
  • the rotating drive can thus perform several functions within the scope of the invention.
  • the linear drive is advantageously designed as a working cylinder, preferably as a pneumatically working working cylinder, or as an electric linear motor.
  • An adjustable stop is advantageously provided to limit the conveying stroke and / or the return stroke of the linear drive. This enables adaptation to different label lengths.
  • an end position shock absorber is advantageously provided for damping the delivery stroke and / or the return stroke of the linear drive, and at least one sensor is provided for detecting the end position of the linear drive.
  • the rotating drive for the carrier belt e.g. training as a stepper motor, as a disc motor, or as a motor provided with a clutch.
  • control unit preferably has a microprocessor.
  • the label tape remains flat on the label detaching edge, despite the differences in tensile force in the tape due to friction in front of and after this edge.
  • a positionally accurate transfer to the label transfer element is thereby achieved.
  • This effect can be improved in a device according to the invention in a preferred manner in that a constantly acting brake is provided between the supply roll and the label detaching edge in order to maintain the tape tension required in the label tape.
  • Fig. 1 shows an embodiment of a labeling device according to the invention. This device is in its starting position for a subsequent labeling cycle.
  • This labeling device uses a label tape 1 in the form of a carrier tape 1a, usually coated with a transparent silicone varnish, on which individual printed pressure-sensitive adhesive labels 1 are located.
  • the label tape 1 is located on a supply roll 2 and is guided by the latter via a deflection roller 20 to a stationary table 21, against which it is pressed by an adjustable, continuous brake 3.
  • This brake 3 serves to maintain a corresponding tension in the label tape.
  • a signal transmitter or sensor 4 serves to detect the position of the individual labels 1 on the carrier tape 1a. He can e.g. a microswitch that detects the edges of the labels or a photoelectric sensor, e.g. a light barrier which emits a signal when the transparent carrier tape 1a is in its gap and allows light to pass through.
  • a microswitch that detects the edges of the labels
  • a photoelectric sensor e.g. a light barrier which emits a signal when the transparent carrier tape 1a is in its gap and allows light to pass through.
  • the parking brake 5 works pneumatically, and the pneumatics are electrically controlled in the usual way.
  • the label transfer element 9 To the left of the longitudinally movable label detaching edge 6 is the label transfer element 9, shown in FIG. 1 in the rest position, with its pneumatic drive 9a.
  • the label transfer member 9 can e.g. be a vacuum-operated suction device, as is known in many ways to the person skilled in the art of labeling devices, so that a detailed representation is unnecessary.
  • a linear drive 10 which only has to be effective in the feed direction, serves to move the longitudinally movable label detaching edge 6.
  • the linear drive 10 can e.g. be an electric linear motor, or a pneumatic or hydraulic working cylinder. Typical of such linear motors is their high specific power and their rapid acceleration. Since the stroke of the linear drive 10 must be different in different label formats, namely slightly less than half the label length or slightly less than half the label division (the label division is the distance between the center of two successive labels 1 on the carrier tape 1 a) this stroke is limited by two adjustable stops 11 and 13, which interact with a connecting element 14 which rigidly connects the linear drive 10 to the label detaching edge 6. Furthermore, two limit switches 16 and 17 are provided in the manner shown for detecting the position of this connecting element 14. The limit switch 17 detects the retracted position of the label detaching edge 6 shown in FIG. 1, while the limit switch 16 detects the advanced position of the label detaching edge 6 shown in FIG. 2.
  • a control unit 15 typically a microprocessor controlled by a corresponding program, has a mains connection 15a and, as shown, is connected to the sensor 4, the rotating drive 7a of the pair of extraction rollers 7, and the limit switches 16 and 17 by lines indicated by dashed lines. likewise with the corresponding (not shown) control valves of the pneumatically operated devices, that is the parking brake 5, of the drive 9a for the label transfer element 9, and of the linear drive 10.
  • the control device 15 controls the chronological sequence of the movement processes according to the invention, as will be described below.
  • the operation of the device according to FIG. 1 is as follows: First, the control unit 15 blocks the motor 7a, so that the pair of take-off rolls 7 stands and clamps the carrier belt 1a and thereby blocks it. Now the linear drive 10 is switched on and moves the label detaching edge 8 forward as far as the stop 11. The abutment against the stop 11 can - like the abutment against the stop 13 - be damped by small shock absorbers, not shown, which are expediently attached to the connecting element 14.
  • the label peeling edge 6 is now advanced by one stroke, which e.g. is smaller than D / 2, ie slightly smaller than half the label length D, this stroke being determined by the distance between the stops 11 and 13. 4B, the foremost label 1 is thereby detached from the carrier tape 1 a and pushed under the suction device 9, but has not yet reached its exact, final position, but is still missing, for example, a few millimeters.
  • the motor 7a is switched on by the control unit 15, and the pulling roller pair 7 moves the carrier tape 1a forward at a low speed until the sensor 4 indicates to the control unit 15 the correct position of the label tape 1.
  • This movement process is indicated by the arrow 22 in FIG. 4B.
  • the label 1 is located at its end exactly under the suction device 9, as is also shown in FIG. 2.
  • the control unit 15 switches on the brake 5 and presses the label strip 1 against the table 21.
  • the linear drive 10 is switched off, e.g. in a pneumatic cylinder this is depressurized, and the motor 7a is switched to rapid feed, so that the pulling roller pair 7 pulls the carrier tape 1a and feeds the take-up reel 8 until the label peeling edge 6 is pulled back into its starting position by the carrier tape 1a , that is, against the stop 13, the limit switch 17 emitting a corresponding signal. Due to this rapid removal process, the carrier tape 1 a is completely removed from the label 1 b, which is located on the sucker 9 and is held onto it by vacuum.
  • this pull-off movement advantageously takes place against a braking force, for example, as shown, against the force of a spring 25 with a flat spring characteristic, or against the force of a one-sided damping cylinder (not shown) .
  • the spring 25 in FIG. 1 is not in the gap between the suction device 9 and the goods to be labeled 12, but rather, for example, in front of or behind this gap.
  • the suction device 9 serving as the label transfer element can transfer the label onto the product to be labeled 12, as is also shown in FIGS. 3 and 4D .
  • the control unit 15 then moves the suction device 9 back into its rest position by means of its drive 9a, and the cycle described can then start again.
  • the label peeling edge 6 each time a label 1b comes to rest on it so that its front edge is flush with the left end of the label peeling edge 6, and this can be adjusted by adjusting the stop 13.
  • the label tape 1 is deflected only on the deflection roller 20, for example, by 45 ° , and then on the label detaching edge 6 by 180 ° , so that the label tape 1 is approximately in the form of a when inserted into the machine elongated hairpin.
  • two such devices can also be used back to back.
  • a mirror plane through the longitudinal axis of the linear drive 10 on which the upper part of FIG. 1 would be mirrored, and one would then have two labeling devices which could label the goods to be labeled 12 from above and from below.
  • the invention prevents the formation of "bubbles" in the labeling tape 1 in the area of the label detaching edge 6 and thereby increases the labeling accuracy.
  • the invention results in a small stroke of the label peeling edge 6 for the transfer of the labels 1b, which also increases the working speed, and moreover - due to the small thickness of the label peeling edge 6 - a very small stroke of the label transfer member 9, especially in comparison to the device DE - A 3 233 546.
