Definitions

  • Adhesive tape applicators serve for the mechanical enclosing of spools and similar round or noncircular bodies carrying wire coils with self-adhering tapes or bands for the purpose of insulating the spool and protecting the wire coils. These bodies or spools together with their wire cOil wrapping will hereinafter be conveniently referred to as coil body or bodies.
  • adhesive tape or band applicators either form a unit with the winding machine already during manufacture of the latter or provide a device which can be mounted at the winding machine according to requirements. In so doing, the adhesive tape or band is typically pulled off a supply spool over different detlecting rollers,
  • tensioning rollers and measuring rollers and delivered to the coil body. After the tape winding or Wrapping operation has been completed the adhesive tape is automatically cut, the beginning of this tape then brought into contact with the next coil body, whereupon the subsequent work cycle begins.
  • Another object of this invention is to provide an adhesive tape applicator for coil bodies which is relatively simple and robust in construction, economical to manufacture, and capable of applying an adhesive tape wrapping to the coil body without damaging the latter.
  • Still a further more specific and prime object of this invention aims at preventing the uncontrolled tangential forces at the coil body during wrapping thereof, by providing a tape withdrawal roller driven by its own motor and means for forming a loaded adhesive tape or band loop of controllable tape tension between the adhesive tape supply roller and the coil body, so that the tangential forces at the coil body can be controlled.
  • the tangential force for the insulation wrapping or winding required at the spool spindle is thus independent of the withdrawal tension and is in the order of magnitude -of the forces necessary for winding of the wire coils, so that there is effectively prevented damage to the coil body and the wire coils.
  • the inventive adhesive tape applying dexice or applicator for the wrapping of coil ⁇ bodies incorporating spools and usually other cylindrical bodies of optional crosssection is characterized by the features of a motor driven withdrawal roller which pulls the adhesive tape or band from a supply roller, a displaceable member incorporating a tension roller for the adhesive tape which is loaded ice by a tensioning element in order to form an adhesive tape loop between the withdrawal roller and the coil body. Additionally, there is provided a pivotable support which can be actuated through the agency of a servo-mechanism for instance.
  • a tape deflecting roller is advantageously located at the pivot axis or shaft of the pivotable support which cooperates with a blocking roller preventing return feed of the adhesive tape, and furthermore, there is provided an elevationally positionable frame which is mounted for raising and lowering movements and which unites the components of the applicator and serves to bring about contact of the adhesive tape with the coil body.
  • FIGURE 1 schematically illustrates the construction of an embodiment of inventive adhesive tape applicator where the support is located in a position during Winding of a coil body with adhesive tape;
  • FIGURE 2 schematically illustrates the applicator of FIGURE 1 as 'viewed from the rear, this figure being turned 180 in the plane of the paper so as to correspond to the spatial orientation of FIGURE 1, the support being rocked away from the coil body;
  • FIGURE 3 schematically depicts a portion of the applicator of FIGURE I, specifically illustrating the support in elevated position, so that the beginning of the adhesive tape can be brought into contact with a coil body for wrapping or winding thereon.
  • the deilecting roller 5 is rotatably mounted at its shaft 5a to -a frame 20.
  • the latter is pivotably mounted at shaft 19 to a stand 30 of the applicator device A so that such frame 20 can be elevationally displaced i.e. raised or lowered, for reasons to be considered shortly.
  • frame 20 can he raised by pushing an operating lever 18 upwardly into the phantom line position of FIGURE l, such lever being mounted at shaft 19.
  • the shaft 6a of the previously considered displaceable tension roller 6 is Connected with a Slide member 11 gliding within an elongated guideway or slot 12 -provided at the frame 20.
  • Slide member 11 is connected via a cable or cord 14 with a slide-loading member, in the case considered such is the one end 13a of a spring 13, the other end 13b of which embraces a pin 32 mounted at frame 20.
  • the cord or cable 14 passes over a turning roller 31 on its way to the end 13a of spring 13.
  • the adhesive band or tape 1a is withdrawn from its supply roller 1 by means of the withdrawal roller ⁇ 4 driven by motor 40, the spring 13 displaces the slide member 11 together with the tension roller 6 to the left of FIGURE l and, thus, forms an adhesive tape or band loop, generally indicated at 1b, and from which this tape la is pulled-olf by the coil body 15 to be wrapped against the resistance of the 3 spring 13.
  • terminal switch 23 actuates a cutter knife 16 for cutting the tape 1a
  • terminal switch 24 deener- Igizes a relay -41 controlled by a control mechanism 42 in order to stop the driving motor 4i? for the withdrawal roller 4.
  • the cam means 50 can be formed of two overlapping plate members 51 Vand 52 fixed by screws 53 or otherwise to the slide member 11.
  • the rearmost plate 51 of- FGURE 2 has a cam surface 51a which acts upon terminal switch 23 controlling the cutter .16.
  • the forwardmost plate 52 has va cam surface 52a for actuating the terminal switch 24 controlling stoppage of the drive motor 4b for the withdrawal roller 4.
  • plate 52 is provided with two elongated slots 54 through which piercingly extend the screws 53, so that the cam surface 52a can be selectively axially positioned with regard to the slide member 11.
  • this expedient thus ⁇ also enables selective varying of the length of tape 1a to be wrapped onto the coil body 15.
  • the adhesive band or tape 1a is cut by an electromagnet-actuated knife or cutter 416 displaceably mounted at a support 22 mounted for instance to be pivotable about the pivot shaft 8a of the detiecting roller 8.
  • the vcutter knife 16 is supported at a bracket 36 having an electromagnet core or armature 33 slidably extending through a block 34 :arranged at the pivotable support 22 and carrying the windings 37 of the electromagnet.
  • terminal switoh 23 actuates the cutter knife 16, specically by energizing the windings 37 via a suitable supply source (not shown) so that core 33 is displaced to the left of FIGURE 1, to thus cut the tape 1a.
  • FIGURE 1 there is shown a roller 43 articulated by 'a lever 44 to the support 22 and urged by a blade spring 45 against the tape 1a. It is also possible to provide a control installation by means of which it is possible to pre-select a number of different predetermined tape winding lengths and during operation it can be adjusted by means of a selector switch, or enables an automatic adjustment of the winding length according to a programmed plan.
  • yContact of the leading tape end with the next coil body 15 to be wound can be realised by raising the frame 20 by upwardly pressing the manual lever 1S mounted at the shaft 19.
  • a servo-control for displacing or rocking the support 22 and which incorporates, for instance, an air cylinder 21 having therein a slidable piston 28 connected by its support actuating piston rod 25 at pivot pin 27 to the pivotable support 22, has its cylinder 21 supplied with pressurized air, or any other suitable iluid medium, through the agency of a valve 55 opened by a relay 56 operatively connected with the control device or mechanism 42.
  • a terminal switch 57 operably connected with the control mechanisrn 42 is mounted in the path of movement of the frame 20 so that when this frame is raised by upward-ly pivoting the .manual lever 18 this terminal switch 57 is actuated, whereby control mechanism 42 energizes relay 56 in a manner to open the valve 55.
  • air is admitted from an inlet supply conduit 58 leading to a suitable source (not shown) through the valve 55 and conduit 59 to the inlet or port 29 communicating with the cylinder 21.
  • the support 22 is pivoted upwards into the position of FIGURE 3, the beginning of the tape being pressed against the coil body 15 to be wound.
  • the manual lever 18 is pressed ldownwards the band or tape 1a then sticks to the coil body 15.
  • the frame member has its inclined surface a bearing against the terminal switch 57 to actuate the latter so that the just-explained operation occurs.
  • the support 22 is in the position of FIGURE 3 the leading tape end is pressed against the coil body 15.
  • the manual lever 18 is rocked back from its phantom line position of FIGURE 1 into the full line position, so that the frame member 20 is lowered and the upper shoe 10 bears against the coil body 15.
  • the coil body 15 is then placed into rotation and winds the tape 1a onto it, the slide member 11 during such time moving continuously towards the right of FIGURE 1 until it contacts the terminal switch 23.
  • the cutter knife 16 is actuated to cut the tape 1a.
  • the button 25 at the Imanual lever 18 is actuated and such causes the control mechanism 42 to act upon the valve relay 55V so that the valve 55 is positioned to allow the pressurized air to escape via the port 29, the conduit 59 and the outlet conduit 60. Consequently, the support 22 rocks away from the coil body 15.
  • Operation of the push button 25 also causes the control mechanism 42 to actuate the relay 41, so that the drive motor 40 is started and the withdrawal roller 4 pulls more tape off the supply roller 1 until a new tape loop 1b is formed, the slide 11 again moving to the left of FIGURE 1, the cam surface 52 actuating the terminal switch 24 to cause the relay 41 to de-energize and to cut-olf this drive motor 40.
