Definitions

  • An apparatus for connecting the rear end of a web of a nearly empty unwinding roll to a front end portion of a web carrying an adhesive strip and pertaining to a new roll to be unwound which includes two pressing rollers for receiving therebetween the unwinding end of the web from one roller and the forward end of the web of a new roller while a cutter is provided between the web rollers and the pressing rollers for alternate cooperation with the rear end portion of the nearly empty web roll to out said rear end portion off after it has been pressed and glued to the front portion of the new web, electromagnetic control means controlled by the rear end of the unwinding web being provided for reducing the speed of the respective unwinding web pror to the cutting off operation of said cutter.
  • the present invention relates to an apparatus for connecting the rear end of an unwinding web of material with the front end of a new web of material, said webs of material being wound to form a roll and being unwound therefrom.
  • the knife is arranged on a pivotable knife head which shortly prior to the unwinding of the web of material is pivoted by the operator in such a way that the knife engages the unwinding web of material which is cut by the simultaneous engagement of the pertaining knife rail.
  • This apparatus has the drawback that an operator must watch the apparatus in order to actuate the same when the web has almost been completely unwound.
  • FIG. 1 is a vertical section through an apparatus according to the invention.
  • FIG. 2 illustrates a section taken along the line II-II of FIG. 1 through a portion of the apparatus.
  • FIG. 3 is a section through a portion of the knife carrier, said section being taken along the line IlI--III of FIG. 2.
  • FIG. 4 is an approximately vertical section through the contact carrier which carries the feeler contacts, said section being taken along the line IV-IV of FIG. 1.
  • FIG. 5 is an approximately vertical section through the contact carrier, said section being taken along the line V-V of FIG. 1.
  • FIG. 6 represents a vertical section through the knife carrier, the adjusting shaft and through a preferred embodiment of the pressing rollers in interengaging positrons.
  • the apparatus according to the present invention is characterized primarily in that the knife is arranged on a knife carrier rotatable by from which the knife protrudes unilaterally and is adapted selectively to cooperate with one of the two grooved bars while the pivoting of the supporting levers carrying the pressing rollers and the grooved bars, which is effected in a manner known per so by a magnet, is controlled by feeler contacts which cooperate with the end of the unwinding web of material.
  • each contact carrier with two parallel feeler contacts the feelers of which are located in the vicinity of the edges of the web of material.
  • the feeler contacts which are respectively associated with the unwinding web of material are made effective by means of a microswitch which is operable by a cam disc coupled to the movement of the knife carrier.
  • the cam disc is arranged on a control shaft carrying a control handle and having connected thereto a sprocket wheel which through a chain is connected to a further sprocket wheel connected to the knife carrier.
  • a stationary holding plate above the knife carrier has outside the path of the web of material adjustably located thereon two abutment screws for the knife.
  • the pressure rollers are in the region of the webs of material equipped with a compressible covering, for example of foam material.
  • a compressible covering for example of foam material.
  • the lining support is also proposed to mount the lining support on a support shaft so that it can pivot due to the force of a tension spring. Furthermore, the lining support is provided with an actuating lever, which, after the web of material has run off, is released by a coupling part, which is arranged on a pivotable lever which supports a tension roller. Due to this indirect operation of the braking device there is achieved a more gentle engagement of the braking device when the device is being started and when the web rolls are being changed.
  • a frame 1 has mounted thereon the roller shafts 2c and 3c of two roller disks 2b and 3b, which receive the webs of material 2 and 3 wound into web rolls 2a and 3a.
  • Each of these webs of material 2 and 3 is guided over a guide roller 4, a tension roller 5 arranged on a pivoted lever 7, and a further guide roller 6 to a cutter support 20.
  • Beneath the cutter support 20 there are arranged two rollers 9 and 10, which are mounted with their roller shafts 9a, 10a on the frame 1.
  • the support lever 11 is loaded by a pressure spring 19, however, it is held in its position by a stop 11a on the support lever 11, which engages in a recess of a pivoted lever 18.
  • the pivoted lever 18 is movably mounted on a pivot shaft 18a attached to the frame 1 and is connected to pull rod 17a of a solenoid 17. When current flows through the solenoid 17, the pull rod 17a moves to the left according to FIG. 1. The pivoted lever 18 thus releases the stop 11a of the support lever 11, so that the pressure spring 19 tilts the support lever 11 and the support lever 12 toward each other by means of the gear rims 9b and 10b.
  • notched bars and 16 are attached to the support levers 11 and 12. One of these bars selectively cooperates with the cutter 21 attached to the cutter support 20.
  • This control shaft 25 is provided with a control handle 25a, by means of which it can be turned in such a way that the cutter 21 which projects from the cutter support 20 cooperates either with the left-hand cutter bar 15 or with the right-hand cutter bar 16.
  • a clamping body 29 with clamping grooves or slots 29a in which the beginning of the new web of material 3 to be connected to the winding-off web 2 of material is clamped by means of the clamping beams 30.
  • the projecting bar of this clamping beam 30 is inserted into the clamping slot 29a by means of a handle 30a for securing the beginning of the web of material.
  • the clamping beams 30 are automatically ejected from the clamping slots 29a.
  • sensing contacts 34 two of which are provided on a contact support 34a attached to the pivotable levers 7.
  • FIGS. 4 and 5 show that the sensing contacts 34 which are equipped with two contacts 34c and a contact spring 34d, have a feeler 34b which holds the contacts 34c open when the web of material 2 passes normally between the contact support 34a and a counter plate 342.
  • the contact spring 34d contracts and the feelers 34b enter a recess 34 of the counter plate 34a. In such case the contacts 34c are closed and the solenoid 17 is excited.
  • the solenoid 17 is excited also when the edge of the web or material 2 or 3 is torn or when with an inclined run of the running-off edge of the material web 2 or 3 the useless section begins.
  • micro switches 31 and 32 In order to make the operation of the device possible even during the change of the web rolls 2a and 3a, on a support plate 33 there are arranged two micro switches 31 and 32, each of which is respectively associated with the sensing contacts 34 of one web of material 2 or 3. These micro switches 31 and 32 are actuated by a cam disk 25b, which is attached to the control shaft 25. This cam disk 25b has a recess which only switches on that micro switch 31 or 32 which is associated with the sensing contacts of the respective web of material 2 or 3 which is winding off.
  • the micro switches 31 and 32 are adjusted along with the turning of the cutter 21 through By this means, the micro switch whose associated web is winding off, is switched on, whereas the other micro switch is switched off, in order to eliminate an excitation of the solenoid 17 during the process of inserting the new web roll.
  • the cutter support 20 is tilted through 180, and the micro switch 31 is switched olf, while the micro switch 32 is switched on. Subsequently, the remains of the web of material 2 which has wound off is removed and a new web roll 2a is inserted. The beginning of this web roll 2a is clamped in the left-hand clamping slot 29a by means of the left-hand clamping beam 30, after the front edge has been provided with an adhesive strip 3.
  • the support levers 11 and :12 together with the pull rod 17a and the pivoted lever 18 have previously been brought into the open initial position. Thus, the device is ready for a further automatic changing process.
  • This braking device 8 comprises a support 8b which supports a brake lining 8a.
  • the said support 8b is adapted to be pivoted by means of a tension spring 8e attached to a pin 8d. Normally, such pivoting is prevented by an actuating lever 8 which is held by a coupling part 8g, which is attached to the pivoted lever 7 carrying the tension roller 5.
  • the coupling part 8g with the pivoted lever 7 pivots so that the actuating lever 81 is released and there occurs a braking f the roller disk 2b.
  • the pressure rollers 13 and 14 may be provided with a cover 13a, 14a. of foam material, so that in place of the former linear contact there occurs a surface contact of the two pressure rollers 13 and 14 which makes superfluous any exact positioning of the beginning of the web of material provided with an adhesive strip, and also results in an improvement of the adhering process.
  • the pressure rollers 13 and 14 are equipped with a stationary cover, so that a well-defined abutment area is provided.
  • a cam disc is shaft coupled for controlled actuation With the knife-carrier means, a pair of micro-switch contact means selectively actuated by said cam disc, and a feeler contact activated alternately through said pair of micro-switch contact means at a time overseeing the emptying respectively new material track web.
  • each of said brake means comprising a brake lining equipped carrier movable to cause the brake lining thereof brakingly to engage the respective roller disc pertaining thereto, spring means continuously urging said brake lining into braking engagement with the roller disc pertaining thereto, control lever means operatively connected to said brake lining equipped carriers and normally holding said brake lining away from the respective roller discs against the action of said spring means, and means operatively connected to said control lever means rendering said control lever means ineffective in response to the rear end of a web being nearly unwound from the roller carrying the same.
