Definitions

  • the invention relates to an automatic label dispenser for attachment to a packaging machine, a conveyor belt or the like. with a supply roll of a label tape with labels arranged on a carrier tape at a distance from one another, the label tape for dispensing the labels by means of a driven Transport roller around a dispensing edge, at which the labels are removed, stepped in a controlled manner depending on the label arrangement on the carrier tape by means of a button or contact, and the empty carrier tape can preferably be wound on a driven take-up roll.
  • the step-by-step transport of the carrier tape takes place by the control of a clutch driving the transport roller.
  • the arrangement of this coupling is bulky and prevents a compact, particularly narrow construction of the label dispenser.
  • relatively large masses must always be accelerated and decelerated again in the control, so that high labeling speeds, especially when labeling with relatively small labels, cannot be achieved.
  • the object of the present invention is to provide a label dispenser of the type mentioned in e, which allows a high labeling speed with a compact structure.
  • the invention provides that the transport roller can be driven at a constant speed
  • the circumferential speed preferably corresponds approximately to the transport speed of the objects to be labeled and a carrier tape clamping device which interacts with the transport roller is provided for the step-by-step transport of the label tape, by means of which the carrier tape is pressed in a controlled manner against the transport roller and thus transported further or is released with free passage of the transport roller and is not transported like this.
  • the carrier tape clamping device can have a pressure roller which interacts with the transport roller and can be pressed and lifted in a controlled manner against the transport roller.
  • the pressure roller can also serve as a deflection guide for the carrier tape, so that few parts are required for the construction of the dispenser.
  • a significant reduction in the stress on the carrier tape and thus the usability of particularly thin carrier tapes can be achieved in that the lifting movement of the pressure roller from the transport roller leads to a shortening of the course of the carrier tape between the transport roller and the winding roll, so that the carrier tape at least briefly during the introduction the braking process becomes tension-free.
  • a carrier tape brake is then provided, by means of which the carrier tape can be held in a controlled manner without obstructing the further travel of the transport roller, so that the carrier tape can always be controlled in an exact position.
  • the carrier tape brake can have a fixed brake abutment and a brake shoe that can be moved approximately perpendicularly against the brake abutment, between which the carrier tape is guided.
  • the brake shoe can then be provided at the free end of a pivoted lever and can be controlled directly or indirectly by the pressure roller of the conveyor belt clamping device, so that transport and braking can be controlled alternately by a single control.
  • a control roller can then be provided on the pivotably mounted lever in a particularly simple manner, which rests on the pressure roller by spring pressure, so that the control movement of the pressure roller can be transmitted via the control roller to the lever carrying the movable brake shoes.
  • the displacement of the pressure roller relative to the transport roller can be easily controlled by a lifting magnet.
  • the stroke frequency of such a solenoid is limited. Therefore, with a high dispensing frequency, the displacement of the pressure roller relative to the transport roller can advantageously be controlled by means of a stepping motor by switching it forward and backward.
  • the pressure roller can be rotatably mounted on an eccentric, in which case the eccentric is controlled by the lifting magnet or the stepping motor.
  • a space-saving structure can be achieved in that the brake shoes and, if applicable, the control roller and at least partially the lever carrying them are arranged in a circumferential groove of the transport roller. the groove on the circumference is partially covered by the carrier tape.
  • the transport and braking of the carrier belt can be carried out in a structurally particularly simple manner in that the pressure roller is provided between the transport roller and a brake abutment and the carrier belt is passed both between the pressure roller and the transport roller and between the transport roller and the brake abutment and that the pressure roller counteracts the transport effect the transport roller can be pressed and, for braking the carrier belt, the pressure roller can be lifted off the transport roller and at the same time can be pressed against the brake abutment.
  • the control can be simplified further in that the pressure roller is pulled against the brake abutment by a spring and is preferably displaceable against the transport roller in a controlled manner by means of a lifting magnet or a stepping motor.
  • the pressure roller can be brought into an intermediate position with a wiping transport roller and brake abutment by a mechanical lifting device.
  • the pressure roller can advantageously be formed by two rollers mounted in a displacement part, with the transport and braking of the carrier belt then being displaced by displacement of the displacement part is controlled.
  • the spacing of the rollers can be chosen practically arbitrarily according to the design requirements, the displacement part expediently has two U-shaped recesses in which the rollers are rotatably mounted.
  • the bearing pin of a roller can advantageously be extended and guided in a longitudinal groove in the carrier wall, as a result of which tilting of the sliding part is impossible and further guidance is saved.
  • the label tape can advantageously be guided over a probe arm that can be pivoted at least in a vertical plane. This makes it easy, for example, to label fruits automatically.
  • the formation of such a probe arm is known for example from German patent 23 08 373.
  • the carrier tape can be guided over a control roller, this control roller having projections on its periphery which engage in corresponding openings in the carrier tape and the arrangement of the projections and openings corresponds to the arrangement of the labels or a multiple or fraction of the label division and is then controllable by at least one with the control roller or a control wheel connected to it via a tap of the lifting magnet or the stepping motor.
  • a microswitch can be used particularly easily as a tap, which is switched by appropriate switching of a cam wheel driven by the control roller.
  • a wide variety of labels can be processed without a significant change in the label dispenser by the label tape carrying the label being guided past a mechanical or optical scanner and the lifting magnet or the stepping motor being controlled via this scanner.
  • the button can be longitudinally adjustable in the direction parallel to the label tape.
  • a fixed disc is used as the brake bearing, which has the same diameter as the transport roller and is aligned with the transport roller and is at least partially wrapped around by the conveyor belt. By arranging this disc, space can be gained for the flying storage of the transport roller.
  • the associated lever can advantageously be fixedly connected to the pivotable eccentric bearing of the pressure roller, so that the control of the pressure roller and the carrier tape brake can be summarized particularly easily.
  • the brake shoe at the end of the lever can be held so that it can be adjusted and clamped, and at least the surface of the brake shoe interacting with the brake bearing can advantageously be made of hard metal to reduce wear.
  • a deflection roller can be provided in a particularly advantageous design parallel to the transport roller and to the pressure roller, this deflection roller being fixedly arranged on the supporting wall and carrying a bearing bracket for the eccentric bearing of the pressure roller at its free end.
  • the label dispenser shown schematically in FIG. 1 has a vertical support wall 1, above which a supply roll 2 of a label tape 3 is mounted.
  • the label tape 4 carrying labels is guided over one or more deflection rollers 5 to a dispensing edge 6, at each of which one of the labels 4 is delivered to identify a good 7.
  • the labels 4 are arranged on a carrier tape 8, which is fed around the dispensing edge 6 via a transport roller 9, a pressure roller 10 and a further deflection roller 5 to a winding roller 11.
  • the goods 7 are passed on a conveyor belt 12 below the dispensing edge 6 and the transport of the carrier belt 8 is controlled, for example, via a light barrier 13 or a switching contact.
  • the transport roller is driven continuously. It has a circumferential groove 14 in which an arm of a pivotally mounted lever 15 is arranged. At the end of the lever 15, a brake shoe 16 is provided, which by a spring 17 arranged at the other end of the arm is pressed against a brake bearing 18 arranged fixed on the supporting wall, so as to form a carrier band brake 19. In the vicinity of the brake shoe 16, a control roller 20 is also provided on the lever 15, which cooperates with the pressure roller 10.
  • the pressure roller 10 itself is mounted in a manner not shown on an eccentric, which enables this pressure roller 10 to be displaced against the transport roller 9. If the pressure roller 10 is pressed against the transport roller 9, the brake shoe 10 is simultaneously lifted off the brake bearing 18 and the carrier belt 8 is transported.
  • the eccentric bearing the pressure roller 10 is reversed by a control after the label 4 has been dispensed at the dispensing edge 6.
  • the pressure roller 10 is lifted so far that the brake shoe 16 rests against the brake bearing 18 by the spring 17 and thus further transport of the carrier tape 8 is prevented.
  • This reversal takes place via a mechanical or optical button 21, which is arranged above the label strip 3 in front of the dispensing edge 6 and controls the braking when the end of a label is reached, while the start of the dispensing process takes place in a controlled manner by the light barrier 13 by releasing the carrier tape brake 19, so that on everyone individually labeled object of the good 7 only a label is applied.
  • the transport speed of the conveyor belt 12 is the same as the take-off speed of the carrier belt 8.
  • the button 21 can be adjusted in the direction parallel to the label strip 3.
  • the height of the carrier wall 1, which carries the entire label dispenser can be adjusted to the item 7 to be marked, and can be adjustable.
  • control of the carrier tape brake 19 and, at the same time, the transport of the carrier tape 8 is carried out not via a button 21, but via a control roller 21 '.
  • This control roller 21 ' has conically extending projections 22 distributed around the circumference, which engage in correspondingly arranged openings in the carrier tape 8.
  • the division of the projections 22 on the circumference of the control roller 21 corresponds to the division of the labels 4 on the carrier tape 8.
  • the application of the labels 4 to differently shaped goods 7 takes place via a vertically pivotable on the support wall 1 mounted probe arm 23, which has a label dispensing head 24 and a feed device 25, by means of which the probe arm 23 is adapted to the good 7 and brought into its correct position for labeling the good 7.
  • the probe arm 23 is provided with a damping device 26.
  • the material 7 itself for example oranges, is guided past the sensing arm 23 via rollers 27, the activation of the label transport being able to be controlled by the movement of the sensing arm 23, or, as in the exemplary embodiment in FIG. 1, also by means of a light barrier.
  • the transport roller 9 is driven continuously.
  • the pressure roller 10 is mounted in an H-shaped sliding part 28, while a further roller 29 is mounted opposite, which cooperates with the brake bearing 18 and thus forms the carrier tape brake 19.
  • the sliding part 28 is, as indicated in Fig. 2, mounted on an eccentric.
  • the eccentric consists of a cylindrical part 30, on which the sliding part 28 is pivotably mounted and an aligned but offset to it another cylindrical part 31 which is pivotally mounted in the support wall 1.
  • a lever 34 is clamped on the cylindrical part 31 and can be pivoted by a certain amount by means of a lifting magnet 35.
  • the lifting magnet 35 is held in its rest position by a non-illustrated spring, in which the carrier tape 8 is clamped between the roller 29 and the brake bearing 18 at the same time via the lever 34, the eccentric and the displaceable part 28.
  • the pressure roller 10 is lifted off the transport roller 9 so that the transport roller can rotate freely without transporting the carrier belt 8. If the transport of the carrier belt 8 is now started by a pulse from the probe arm 23 or another arrangement, the lifting magnet 35 is excited, it pulls in and lifts the roller 29 from the brake bearing 18 via the lever 34 and presses the pressure roller 10 against the transport roller '9, whereby the carrier tape 8 is transported further.
  • the winding roller 11 is always driven via a slip clutch. As soon as a label has been dispensed and attached to the good 7, the lifting magnet 35 is switched over again by the control roller 21 ', so that the carrier tape brake 19 comes into operation again and brakes the carrier tape.
  • a lifting device 36 is provided, which is shown in more detail in FIG. 4.
  • a bolt 37 is guided in the supporting wall 1 against a spring 38.
  • the bolt has an actuation button 39 at one end and a cone piece 40 at its opposite end.
  • the transport roller 9 is driven by two friction rollers 41 arranged in the space 33, which can be driven by friction via a drive shaft (not shown). For example, when labeling oranges, many such label dispensers can be arranged side by side and driven by a single drive shaft. To drive the winding roller 11, the transport roller 9 can be provided with a shaft piece 42 opposite the friction rollers 41.
  • the pressure roller 10 which is mounted on an eccentric, is arranged between the brake bearing 18 and the transport roller 9 and is accordingly wrapped around by the carrier tape 8.
  • the pressure roller 10 is pressed against the transport roller 9, so that the carrier belt 8 is transported in the direction of the arrows by the always driven transport roller 9, while in FIG. 6 the pressure roller 10 is lifted off the transport roller 9 and against the brake bearing 18 is pressed.
  • the carrier belt 8 is braked by the carrier belt brake 19 and there is no longer any tension at the end of the wrapping of the transport roller 9, so that further transport is prevented by the friction between the transport roller 9 and carrier belt 8.
  • the transport roller 9 is cantilevered in the carrier wall 1. Between the carrier wall 1 and the transport roller 9, a disk serving as a brake bearing 18 is fixedly arranged on the carrier wall 1 in alignment and of the same diameter. Both this disc and the transport roller 9 are partially wrapped around the circumference of the carrier belt 8, as shown in Fig. 7 can be seen.
  • a deflection roller 5 is fixedly arranged above it, at the free end of which a bearing carrier 43 for an eccentric bearing 44 is provided, in which one side of the pressure roller 10 is received.
  • the pressure roller 10 is rubber-coated, it is freely rotatable on a cylindrical part 30 'of the eccentric bearing 44.
  • Cheek pieces 45 are provided between the cylindrical part 30 'and the cylindrical parts 31' forming the eccentric.
  • a lever 15 ' is provided on the cheek piece 45 on the support wall side, and a brake shoe 16' is screwed onto its free end.
  • the plate-shaped brake shoe 16 ' is made of hard metal to reduce wear and has a longitudinal slot 46 for readjustment when worn and for initial adjustment.
  • the brake shoe 16 interacts with the disk-shaped brake bearing 18 and for this purpose a lever 34 is arranged on the cylindrical part 31' penetrating the carrier wall 1 and is coupled to the lifting magnet 35.
  • the pressure roller 10 is lifted from the transport roller 9 by rotation about the cylindrical part 31 'and at the same time the brake shoes 16' are pressed against the brake bearing 18.
  • the solenoid 35 When tightening the solenoid 35 the brake shoe 16 'is lifted off the brake bearing 18 so that the carrier tape 8 which runs between the brake bearing 18 and the brake shoe 16' is no longer clamped but is released. Due to the pivoting movement of the lever 34, the pressure roller 10 is simultaneously pressed against the transport roller 9 and thus the carrier belt 8 is further conveyed by the continuously rotating transport roller 9.
  • a lifting device 36 is provided in the carrier wall 1, through which the lever 34 can be pivoted against the action of the spring 47 via an actuating lever 39' and a lever 48.
  • the lifting device 36 is only indicated schematically in FIG. 7.
