Definitions

  • the invention relates to driving modules for driving fastening means connected to one another by means of a connecting means to form a fastener tape and rolled up into a roll of tape into a workpiece, these driving modules being mounted on a tool bridge, in particular in the context of industrial production.
  • These drive modules are used, for example, in the manufacture of prefabricated house modules.
  • U.S. 4,898,316 A discloses an automatic nailing machine for nailing unassembled pallet parts from above and below, the nails being present in a magazine, in particular in the form of a nail tape rolled up to form a tape roll.
  • the automatic nailing machine has at least two nailing tools.
  • a corresponding magazine is attached to each of the at least two nailing tools.
  • the tool bridge In the case of previously known drive modules, for example the "Toolmatic Series CT550" sold by ITW Fixing Systems GmbH, the tool bridge must be stopped when the fasteners in the magazine are running low. In addition, several tools are often used on a tool bridge, which have to be filled at different times. In order to minimize the number of stops, modules whose magazine is not yet completely empty are therefore often refilled with a stop, which means that the driving agents still in the magazine are no longer used and are thrown away.
  • the object of the present invention is to improve these disadvantages, in particular to shorten the duration of the machine downtime when refilling fasteners, and more preferably to reduce the number of necessary stops and to use all fasteners if possible.
  • a driving module for driving fastening means which are connected to one another by means of a connecting means to form a fastener tape and rolled up into a roll of tape, into a workpiece, the driving module having a driving unit, the driving module, preferably the unit carrier, if present (see below).
  • the driving unit has a mounting section for mounting the driving module on a tool bridge, the driving unit having a driving drive which acts with a driving force on the fastening means to be driven via a driving ram that can be displaced in the driving direction, and a magazine having at least one output section is attached to the driving module , via which the fastener tape can be led out of the magazine from the tape roll, and wherein the magazine has at least one fastening section for fastening the magazine or parts thereof a n has the driving module, wherein the driving module has a unit carrier and the driving unit is arranged on the unit carrier and the driving unit as such can be brought up to the respective workpiece in a moving motion by means of a drive drive and for this purpose is guided displaceably in the driving direction via an assembly guide on the unit carrier .
  • the driving module has a unit carrier and the driving unit is arranged on the unit carrier and the driving unit as such can be brought up to the respective workpiece in a moving movement by means of a drive drive, preferably pressed, and for this purpose on the unit carrier via an assembly guide the driving direction slidably guided.
  • the approach drive is preferably designed as a wedge drive, i.e. by moving a wedge perpendicular to the driving direction, with the wedge located above the driving unit, the driving unit can be raised and lowered.
  • the magazine is coupled to the unit carrier in such a way that a tape roll inserted in the magazine is essentially, preferably completely, decoupled from the approach movement of the driving unit.
  • This makes it possible to use a larger magazine with a higher capacity of fasteners.
  • decoupling the weight of the Fastening means are not moved along every time the driving unit is brought up, which thus saves energy and puts less stress on the components, so that a higher magazine weight can be withstood due to the increased magazine capacity.
  • This version is already suitable with an otherwise common magazine for rolled up fastener tapes (i.e. without multiple tape roll holders) to increase the capacity of the magazine without major negative side effects and thus to reduce the number of stops for refilling the magazine. It is therefore not necessary for the magazine to have at least two tape roll holders for receiving at least one tape roll each; and in a correspondingly broader claimed form, this embodiment in particular can also be the subject of a divisional application, whereby it is also possible to pursue other embodiments as a divisional application.
  • Essentially decoupled is preferably understood to mean that the core of the roll or the roll center point is static, and thus also the part of the roll that is still rolled up, while the unrolled piece of tape can move with it.
  • the magazine can have at least two tape roll holders for receiving at least one tape roll each.
  • fastening means from two different tape rolls stored in the magazine can be provided for the driving process.
  • the object is also achieved in particular by a magazine for a drive module according to the invention and / or a magazine cassette for a magazine according to the invention.
  • the tape roll holders are preferably arranged next to one another.
  • the axes of the tape reels inserted in the tape reel holders in the magazine are preferably essentially coaxial with one another.
  • a tape roll holder is preferably a compartment in the magazine or a predetermined space in the magazine for a tape roll, which is preferably separated by a partition from the other tape roll holder defining the space.
