Definitions

  • the invention relates to a timing device for controlling the joining of the trailing and leading ends of two webs being fed successively to a processing machine, such as a packing machine, whilst maintaining predetermined spacings between centering markings provided on the webs, wherein the leading end of the second material web is held in preparation, at the mouth of a pair of displaceable rollers between which the other web runs, said rollers being adapted to be pressed one against the other for connecting the trailing end of the first material web with the leading end of the second material web.
  • the wrapping material is provided with imprints or legends which must appear in certain predetermined positions on the wrapped object.
  • the printed wrapping material is supplied wound on storage reels. It is known to arrange two mountings for these storage reels alongside the packing machine. Whilst one reel is being used, the second reel can be prepared on its mounting and its leading end is fed into the machine when the first web is used up. Hitherto it has been necessary to stop the packing machine for feeding and aligning the leading end of a new material web. The trailing end of the old material web was always joined by glueing to the leading end of the new web.
  • the material webs carry regularly spaced centering marks which are provided simultaneously with the printing. When the two ends of two strips of webs are joined, care must be taken that the correct distance is mentioned between the last centering mark on the used web and the first on the new web.
  • the stopping of the packing machine for joining the end of the used web to the leading end of the new web causes an undesirable interruption of the operation.
  • the invention seeks to provide a device whereby this operation may be efiected automatically, without having to stop the machine.
  • a timing device comprising a sensing member capable of r being actuated by the trailing end to initiate a signal for joining the ends together, the signal being stored in a memory at least until effective joining can take place and a signal transmitter synchronized with the machine or with the passage of the material web carrying periodically repeated imprints to trigger off the joining if the memory contains a signal transmitted by the sensing member.
  • FIG. 1 shows diagrammatically a device according to the invention
  • FIG. 2 shows on an enlarged scale, the rollers supplying the material webs
  • FIG. 3 shows two possibilities of joining the trailing end of the used material web to the leading end of the new material web
  • FIGS. 4 and S are a top view and side elevation, respectively, of a mechanical memory for operating the contact member of the rollers connecting the material webs;
  • FIG. 6 is an electric circuit diagram of the said memory
  • FIGS. 7 and 8 are details of another embodiment, using a different storage principle.
  • a machine shown only diagrammatically in FIG. 1, for example a packing machine 1, receives a web of material 2a, from which the machine makes wrappers.
  • the web 2a is provided with imprints, not shown, and with centering marks 3, the position of which are indicated by short lines perpendicular to the web in FIG. 1. These centering marks 3 are equidistantly spaced apart by a distance 1: (FIG. 3).
  • the web 2a is reeled off a storage reel 4, mounted in a support 50.
  • a similar support 5b carries a reserve roller 6 from which a material web 2b is fed into the machine 1, when the material web 20 coming from the roller 4 has been used up.
  • the material web 2a is fed from the storage reel 4 over a tensioning device, comprising two rollers 8, 9, mounted on a rocker arm 7 and two stationary rollers 10, 11, to a table 12a. From this table, the material web 20 is fed over a press roller 13 and a guide roller 14 to the machine 1. Equalizing rollers 15, 16, 17 may be provided between the roller 14 and the machine 1, of which the rollers 15 and 17 are stationary and the roller 16 displaceable, as indicated in the drawing, causing the web to form a loop. Adjustment of the roller 16 makes it possible to change the size of the loop and to adapt it to the spacing between the centering marks.
  • the material web 2b passes over an identically constructed tensioning device to table 12b. When it is supplied to the machine 1, it passes over a counter-roller 18 and then along the same path as the Web 2a.
  • the pressure roller 13 is mounted on a lever 19, pivotable about the spindle of the roller 14 and may be pressed against the rigidly mounted counter-roller 18, for example, by means of a pressure magnet 20.
  • the two rollers .13 and 18 are positively connected by a driving belt 21 so that no accelerating forces can occur when the two rollers are pressed against each other.
  • the table 12a carries a sensing member 22a and a brake 23a.
  • the sensing member 22a responds, when the end of the material web 2a passes thereunder.
  • the brake 23a prevents the web 2a from running backwards.
  • the sensing member 22a may be longitudinally displaceable on the table 12a to enable it to be adapted to the varying gaps between the centering marks.
  • the table 12b carries an equivalent sensing member 22b and a brake 23b.
  • FIG. 2 shows, on an enlarged scale, the ends of the tables 12a, 12b and the rollers 13 and 18. The process of joining the two material webs 2a, 2b will now be explained with reference to this figure.
  • an operator pulls the leading end of the material web 2b off the reel 6 and threads it through the tensioning device onto the table 12b until its leading edge 2b is exactly over the center of the press roller 18.
  • the first centering mark 3 is spaced at y from the leading edge 2b. If necessary, the web is trimmed accordingly.
  • an adhesive strip 24 is so glued to the underside of the web 2b that it projects beyond the edge 2b and rests with its non-sticky surface on the press roller 18.
  • the sticky surface of the adhesive strip 24 is facing outwardly.
  • the adhesive strip must surround the roller 18 sufficiently to make contact with the material web 2a and to adhere thereto, when the roller 13 is pressed against the roller 18.
  • the material webs may be joined in two ways. Either the edges of the two webs are one behind the other, or the two webs 2a, 2b overlap one another by an amount 2. It is only necessary that the distance between the last or penultimate centering mark on the web 2a and the first centering mark on the web 2b corresponds to the spacing between the other centering marks on both webs.
  • FIGS. 4 and 5 An embodiment of a memory device is shown, by way of example, in FIGS. 4 and 5, whilst the associated electric circuit diagram of the arrangement is shown in FIG. 6.
  • the next of the pins 31 to 34 passing within the range of the electromagnet is moved into a storage position, shown for the pin 31 in FIG. 5.
  • two electric switches 37, 38 are arranged along the periphery of the disc 30 and are operated by the contact pins 31 to 34, when one of these has been moved into the storage position by the magnet 35.
  • the disc revolves in the direction of the arrow 5 so that a contact pin moved into the actuating position by the magnet 35 actuates first the switch 37 and then the switch 38.
  • a return member 39 pushes the pin from the storage position back into the inoperative position when the disc 30 continues to revolve.
  • FIG. 6 showing two switches arranged in the sensing devices 22a, 22b of FIG. 1.
  • a relay 1 actuates the switching contact a, and a whilst a relay B actuates the switching contacts b1 and b2.
  • the trailing edge of the material web 2a closes the switch of the sensing member 22a.
  • This causes the magnet 35 to be energized so that, for example, contact pin 31 is pushed into an operating position.
  • a signal lamp 40 lights up. Since the machine continues to run, the disc 30 rotates so that the switch 37 is closed by the contact pin 31 after a certain time interval.
  • the relay A is energized and the contacts a; and a close, causing the magnet 20 to be energized.
  • This magnet presses the roller 13 against the roller 18, and the web 2a is joined to the web 2b.
  • the pin 31 closes the switch 38 which energizes the relay B.
  • This relay actuates the contacts b1 and b2 so that the magnet 35 and the relay A, and with it also the press magnet 20, are de-energized.
  • the relay B and the signal lamp remain energized until a new storage reel 4 has been prepared.
  • FIGS. 7 and 8 uses another storage principle. It comprises a cam plate 41, running synchronously, for example, at the transmission ratio of 1:1, with the centering marks 3 on the material webs 2a and 2b, and driven by the machine 1.
  • the switches 37 and 38 are actuated by the cam 42.
  • the cam plate revolves in the direction of the arrow S so that first the switch 37 and then the switch 38 are actuated.
  • the operation of this embodiment will be explained with reference to the circuit diagram in FIG. 8.
  • This circuit diagram shows the two switches arranged in the sensing members 22a, 22b in FIG. l.
  • the relay A actuates the contacts 01, a2 and 03, whilst the relay B actuates the contacts b1 and b2.
  • the sensing member 22a is actuated by the trailing edge of the material web 20, the signal emitted by the sensor 22a is recorded in the system and stored. Since the cam plate 41 with the cam 42 revolves in the direction of the arrow, the switch 37 is first closed after a certain time interval.
  • the relay A is energized, the contacts a1, a2 and a3 close and the press magnet 20 is energized.
  • the magnet presses the roller 13 against the roller 18 and the trailing end of the web 2a is joined to the leading end of the web 2b.
  • the cam 42 closes the switch 38 and the relay B is energized, actuating the contacts b1 and b2, so that the relay A and the press magnet 20 are de-energized.
  • both the sensing devices 22a, 22b and the switches 37 and 38 are displaceable.
  • the described mechanical transmitter may also be replaced by a photo-electric transmitter.
  • the cam of the cam plate is replaced by a centering mark on the web and the switches 37 and 38 by photo-electric cells.
  • the storage of the signal emitted by the sensing device 22a or 22b may also be effected, for example by a timing relay, as known in the art.
  • the adjustment of the machine from the material webs 2a or 2b to material webs with dilferently spaced centering marks may be effected selectively as follows:
  • the sensing devices 22a and 225 may have to be adjusted in all three cases.
  • a processing machine for joining a pair of webs at a trailing and leading end whilst maintaining predetermined spacings between centering marks provided on the webs
  • a pair of displaceable rollers between which the leading end of one web is held whilst the other web runs therethrough, means for urging said rollers one against the other for joining the trailing end of said other web to said leading end
  • a timing device comprising a sensing member capable of being actuated by the trailing end to initiate a signal for joining the ends together, a memory for storing said signal until effective joining can take place and a signal transmitter synchronized with the machine to trigger off the joining if the memory contains a signal transmitted by the sensing member.
  • a device in which a table is arranged in front of the displaceable rollers for carrying out the preparation to the leading end of the web.
  • a device in which a disc driven synchronously with the passage of the centering marks serves as the memory, contact pins on said disc and a first magnet controlled by the sensing member being provided to displace said contact pins from an inoperative position into a storage position.
  • a device in which said disc functions as a transmitter.
  • a device in which a second magnet actuates the displaceable rollers to initiate the joining of the webs upon actuation of a switch by said contact pins in the storage position.
  • a device in which a time relay serves as said memory.
  • a processing machine for joining a pair of webs at a trailing and leading end whilst maintaining predetermined spacings between centering marks provided on the webs
  • a pair of displaceable rollers between which the leading end of one web is held whilst the other web runs the-rethrough, means for urging said rollers one against the other for joining the trailing end of said other web to said leading end
  • a timing device comprising a sensing member capable of being actuated by the trailing end to initiate a signal for joining the ends together, a memory for storing said signal until effective joining can take place and a signal transmitter synchronized with the passage of the web to trigger off the joining if the memory contains a signal transmitted by the sensing member.
