Definitions

  • the invention relates to an apparatus and a method for splicing label strips of the type described in the preambles of claims 1, 25 and 16, 17, respectively.
  • a recurrent problem with labeling machines is the fact that used label tapes must be connected to a new label tape without changing the production speed or production parameters.
  • devices of this type are known.
  • the splicer includes an anvil roll and a pressure roller located directly at the splice site.
  • Anvil roll and pressure roller are located on both sides of the label strip, so that the label strip passes between the two rollers.
  • the pressure roller is movable in the direction of the anvil roll and can briefly exert a higher pressure on the intermediate label tape.
  • two pairs of Nachschrollen are preferably provided, one of which is resiliently mounted in each pair. Again, the label tape passes between the rollers of each pair.
  • the resilient Nachdschreibrolle constantly exerts a depending on the need according to the thickness of the label strip adjustable contact pressure on the opposite, fixed Nachdschreibrolle the same pair.
  • Each label tape to be used in this splicer must be equipped at its trailing end with a special adhesive layer and a signal generator which controls the splicing operation; There are therefore only special label tapes to use.
  • the conveying path in front of the splicing device contains two branches, which are alternately used to convey the leading and trailing label strips. In the currently not active branch of the conveying path a label tape is held in readiness, so that it can be attached immediately and without interruption of production to the trailing end of the leading, old label tape. At least one label is manually removed from the new label tape and the thus prepared beginning inserted into the splicing device, to the pressure roller.
  • the label-free beginning of the new label band is pressed in the direction of the adhesive at the end of the old label band as soon as it is in the gap between the anvil roller and the pressure roller located. Subsequently, the splice passes through the Nachdrückrollen, with a further pressure on the splice with the overlapping spliced band areas is exercised. However, it is unavoidable that this pressure is exerted on the labels, which could complicate the subsequent detachment of the labels. In addition, the known device requires a great deal of care from the operator when preparing and inserting the trailing new label tape.
  • the label-free beginning is positioned so that the entire adhesive area after splicing is on the carrier tape of the trailing label tape and does not project beyond the beginning edge or on a label.
  • the distance between the last label before the splice and the first label after the splice should not be too large.
  • the label-free beginning must move together with the pressure roller in the direction of the anvil roll, so that an operator must also take into account the time required for this movement and the longer path required for this, which is difficult to do manually.
  • the DE 31 19 109 shows a device and a method for changing supply rolls in a labeling machine, in which a drive withdraws a label-carrying carrier web from a first or second supply roll and feeds an intermittently promotional label dispenser. To perform the change automatically and without interrupting the Etikettierbetiiebs, a memory loop is generated between the drive and the label dispenser.
  • the invention is thus based on the object to provide an apparatus and a method for splicing tape labels, with which the label tapes can be spliced without a high, experience prerequisite, manual effort accurately and at high speed.
  • a defined end edge and / or a defined splice region is produced during the conveyance of the leading label strip on the leading label strip whose position can be accurately determined and tracked. This eliminates the need to position a label tape exactly in the conveying path.
  • separating device By arranged in the conveying path in front of the splicing station separating device can do without manual work an exact defined end edge of the leading label tape are generated, the distance to the splicing station is known. In addition, the most unusable last labels a label tape can be separated without the need for additional manual effort.
  • a label-free splice region can be generated at a defined location on the leading label tape without manual work.
  • this deflecting edge is assigned according to the invention a guide recess into which the label tape can be pressed as soon as the tape is separated and / or a label detached got to.
  • the deflection can be set in a structurally simple way during conveying out of action, but can be activated immediately as soon as it is needed.
  • a removable label receiving surface provided on the label removal means provides a means of removing the detached label in a defined manner without the risk of the label sticking to undesired locations.
  • the receiving surface is connected to the pivot lever such that both could be brought together in their operative position and swung out of this operative position.
  • the splicing station contains splice jaws which can be pressed against the label band and which are movable along a predetermined region of the conveying path. In this way, it is ensured that the pressure applied to solidify the splice can be applied uniformly and uniformly over the entire splice without printing on any labels.
  • the splice blocks are displaceable along a guide.
  • the splice station includes a suction mount therefor.
  • each branch of which is provided with at least one respective label removal device, but may also each contain a separating device, simplifies the operation of the device and reduces the type and number of movements to be performed by the label tapes.
  • the control of the device according to the invention is particularly simple, and in principle requires only a sensor which detects a position of a label in the conveying path, preferably after the splicing station. If this position is known, it can be determined from the known distance of the sensor to the separator and / or the label removal device and from the known dimensions of the label tape, i. In particular, the dimension of the labels in the conveying direction and the distance between the labels on the label tape, to be determined exactly when can be cut and where cut or when a label is in a position where it can be removed from the label tape. With this sensor can be further determined how large the gap caused by the gap between the immediately before the splice and the immediately after the splice is arranged label, which can optionally be used to control subsequent labeling or the like.
  • the trailing label tape should also be cut. Since in the apparatus according to the invention and the method according to the invention, the beginning of the trailing label tape does not have to be label-free, this can be done in the usually very narrow space between two labels, so that the This resulting initial edge is in a largely optimal register alignment with the labels. Also in this way an excessive gap between the labels in front of and behind the splice is avoided.
  • the label bands 2, 3 are of conventional type and each contain a carrier tape 4, on one side of which self-adhesive labels 5 of the same size and with uniform spacing are preferably applied, which are detachable from the carrier tape 4 in a labeling machine.
  • the label strips 2, 3 are identical in their design. Furthermore, to simplify the illustration, labels 5 are drawn only on a part of the label tape 2, although both label tapes 2, 3 are provided with the labels 5.
  • the size of the labels 5 and their spacing on the carrier tape 4 of both label tapes 2, 3 are known and can be set to a not shown control.
  • Both label bands 2, 3 are withdrawn from a supply, for example a supply roll on a conventional turntable, or the like, not shown, and with the aid of a Conveyor 6, which is a driven belt roller in the illustrated embodiment, conveyed in a conveying direction A by the device 1.

  • the guide 9a, 9b each contain a guide rod, the defined front and rear end stops 10 are assigned, so that the splice jaws 8a, 8b between the end stops 10 are ball-bearing displaced.
  • the pressing movement B of the splicing jaws 8a, 8b is effected by suitable means, for example pneumatically.
  • the movement along the double arrow C is effected by the moving in the conveying direction A label tape, the splice jaws 8 a, 8 b are pressed symmetrically to each other and from both sides with a force against the label strip sufficient that the splicing jaws 8 a, 8 b through the label tape be dragged along.
