Definitions

  • the present invention relates to a device, used in an apparatus for alternately unrolling and supplying strip-like materials, e.g., strip-like wrapping papers for wrapping cigarettes from at least two rolls without interrupting supply of the strip-like materials.
  • strip-like materials e.g., strip-like wrapping papers for wrapping cigarettes from at least two rolls without interrupting supply of the strip-like materials.
  • the European patent application published as EP-A-0 273 286 discloses an apparatus for splicing a replacement web.
  • the apparatus comprises first and second web supply means for alternatively supplying a web to splicing means located in a joining path.
  • Cutter means are provided for severing the first web to establish a trailing edge and to sever the second web to establish a leading edge thereon.
  • the splicing station includes supply means for providing splice tape strips having a self-adhesive surface. Transfer means transfer the adhesive strips to stamper means.
  • a stamper driving mechanism reciprocates to apply the adhesive strips to the leading and trailing edges of the webs to be connected.
  • EP-A-0 273 287 discloses a splicing apparatus comprising a guide for guiding the moving web along a predetermined path.
  • the first and second webs to be joined are aligned such that a lap joint is formed between the leading edge of the replacement web and the moving web.
  • a positioning device applies an adhesive strip in a direction perpendicular to the direction of the moving web.
  • the adhesive strip is applied to the two webs by means of a pair of pressure rollers.
  • Another conventional device of this type is disclosed in Published Unexamined Japanese Patent Application No. 63-162434.
  • This joining devices overlays a leading end portion of a new wrapping material unrolled from the other roll on a trailing end portion of a strip-like wrapping material unrolled and supplied from one roll, and joins the trailing and leading end portions of these wrapping materials by a joining tape.
  • the conventional joining device since the trailing and leading end portions of the wrapping materials are joined while they overlap each other, the overlapping portion may cause troubles in the following wrapping process or the like.
  • a joining tape must be supplied to both the trailing end portion of the already supplied wrapping material, and the leading end portion of a new wrapping material, resulting in a complicated supply mechanism of a joining tape. The complicated mechanism also impairs reliability of an operation.
  • the present invention has been made to eliminate the drawbacks of the conventional joining device, and has the object to provide a device which mates the leading end of a new strip-like material to the trailing end of the already supplied strip-like material, and joins the trailing and leading end portions of these strip-like materials by a joining tape in this state. It is another object of the present invention to provide a joining device which has a simple structure, and can improve reliability of operation.
  • a joining device is provided as defined in claim 1.
  • the joining device comprises a joining preparation path for conveying a strip-like material.
  • a stamper base is arranged midway along the joining preparation path.
  • a first guide path is connected to an upstream end portion of the joining preparation path.
  • a first strip-like material unrolled from a first roll is fed to the joining preparation path through the first guide path.
  • a second guide path is connected to the middle portion of the joining preparation path on the upstream side of the stamper base.
  • a second strip-like material unrolled from a second roll is fed to the joining preparation path through the second guide path.
  • First and second feed mechanisms are arranged in correspondence with the first and second guide paths.
  • a convey mechanism is arranged on a downstream end portion of the joining preparation path.
  • the first strip-like material is continuously supplied to a device for executing the next process through the stamper base by the first feed mechanism and the convey mechanism.
  • the second strip-like material is fed to a portion of the stamper base by the second feed mechanism, and stands by in a state wherein its leading end is aligned with a predetermined position of the stamper base.
  • the joining device comprises a stamper.
  • the stamper has a suction surface capable of holding a joining tape by suction.
  • the joining device comprises a joining tape supply mechanism which supplies a joining tape to the suction surface of the stamper.
  • the joining device preferably comprises a cutter mechanism for cutting the joining tape by a predetermined length. The cut joining tape piece is held on the suction surface of the stamper by suction.
  • the stamper is preferably pivoted through about 90°, so that the suction surface which holds the joining tape piece by suction opposes a predetermined position of the stamper base.
  • the joining device also comprises a stamper driving mechanism for driving the stamper toward the stamper base.
  • the joining device is supplied with the first strip-like material, i.e., the already supplied strip-like material through the joining preparation path and the stamper base.
  • the second strip-like material stands by in a state wherein its leading end is aligned with the predetermined position of the stamper base.
  • the stamper is operated to join the trailing end of the first strip-like material with the leading end of the standby second strip-like material by a joining tape.
  • the second strip-like material is then supplied to be continuous with the first strip-like material.
  • the trailing end of the first strip-like material and the leading end of the second strip-like material are joined by a joining tape while mating them with each other. Therefore, the joined portion of the first and second strip-like materials will not cause a trouble in the following wrapping process or the like. Only one joining tape is needed, and hence, a structure such as a joining tape supply mechanism can be simplified. As a result, reliability of an operation of the device can be improved.
  • the joining device of this embodiment is a device for joining the trailing end of a strip-like wrapping material for forming a package of cigarettes to the leading end of a new wrapping material.
  • Fig. 1 shows a joining preparation path 1.
  • the joining preparation path 1 extends in the vertical direction, and is mainly constituted by a plurality of pairs of guide plates 2 which oppose each other at predetermined intervals.
  • a stamper base 3 is arranged midway along the joining preparation path 1.
  • the stamper base 3 has a flat receiving surface 4 extending along the joining preparation path 1 to oppose it.
  • the central position on the receiving surface 4 is defined as a joining position P.
  • the upper end of the joining preparation path 1 is connected to a first guide path 5.
  • Fig. 1 illustrates a portion of the first guide path 5.
  • the upstream side of the first guide path 5 is connected to a first roll formed by winding a strip-like material, e.g., a first wrapping material A1.
  • the first guide path 5 guides the first wrapping material A1 unrolled from the first roll to the joining preparation path 1.
  • a first feed mechanism 6 for the wrapping material A1 is arranged at the terminal end of the first guide path 5, e.g., a connected portion between the first guide path 5 and the joining preparation path 1.
  • the first feed mechanism 6 comprises a base feed roller 7 constituting a portion of the first guide path 5 and a pinch feed roller 8 which is in rolling contact with the base feed roller 7.
  • the pinch feed roller 8 is attached to the distal end of a pivot arm 9. When the pivot arm 9 is pivoted, the pinch feed roller 8 can approach/separate from the base feed roller 7.
  • the pinch feed roller 8 is driven only when it is in rolling contact with the base feed roller 7.
  • the first feed mechanism 6 feeds the first wrapping material A1 from the first guide path 5 to the joining preparation path 1.
  • the mechanism 6 can guide the leading end of the first wrapping material A1 to the stamper base 3 to be aligned with the joining position P.
  • a register mark (not shown) is printed on the first wrapping material A1 to be separated from its leading end at a predetermined interval, and a sensor 10 for detecting the register mark is arranged along the first guide path 5.
  • the operation of the first feed mechanism 6 is controlled in accordance with the detection signal from the sensor 10.
  • a length from the leading end to the register mark of the first wrapping material A1 is set to be equal to a convey distance of the first wrapping material A1 between the sensor 10 and the joining position P. Therefore, when the sensor 10 detects the register mark, the operation of the first feed mechanism 6 can be stopped to align the leading end of the first wrapping material A1 with the joining position P.
  • a second guide path 11 is connected to the joining preparation path 1 to be located at a downstream side of the first guide path 5 and at an upstream side of the stamper base 3.
  • a second feed mechanism 12 is arranged at a connecting portion between the second guide path 11 and the joining preparation path 1.
  • the upstream side of the second guide path 11 is connected to a second roll formed by winding a second wrapping material A2. Since the second feed mechanism 12, and the like have the same structures as those of the first feed mechanism 6, and the like, the same reference numerals denote parts having the same functions as those described above, and a detailed description thereof will be omitted.
  • a pair of suction brake units 13 and 14 are arranged above the stamper base 3 to sandwich the joining preparation path 1 therebetween.
  • One suction brake unit 15 is arranged below the stamper base 3.
  • These suction brake units are connected to negative pressure sources, and can hold the corresponding first and second wrapping materials A1 and A2 guided to the joining preparation path 1 by suction. More specifically, when the leading end of the wrapping material A2 unrolled from the second roll is aligned with the joining position P, i.e., in a joining preparation state, the leading end portion is held by suction by the suction brake unit 13. Therefore, the leading end of the second wrapping material A2 can be prevented from being accidentally moved.
  • the joining preparation path 1 is connected to a convey mechanism 21.
  • the convey mechanism 21 comprises a guide path 17, extending from the lower end of the joining preparation path 1, for guiding one wrapping material toward the next process.
  • the convey path 17 is defined by some guide rollers 18.
  • a base feed roller 19 and a pinch feed roller 20 which are basically the same as the base feed roller 7 and the pinch feed roller 8 described above, are arranged to be located near the lower end of the joining preparation path 1.
  • the rotational speed of the pinch feed roller 20 is variable. Therefore, if the first wrapping material A1 is assumed to be a wrapping material in use, the wrapping material A1 is unrolled beyond the joining position P of the joining preparation path 1. Then, the unrolling operation is taken over by the base feed roller 19 and the pinch feed roller 20, so that the wrapping material is fed toward the next process via the convey path 17.
  • a sensor 16 for detecting another register mark (not shown) printed on each of the first and second wrapping materials A1 and A2 is arranged below the suction brake unit 15 described above.
  • the other register mark is printed at a position separated from the trailing end of each wrapping material by a predetermined length.
  • the trailing end of the wrapping material A can be easily aligned since the unrolling speed of the wrapping material can be varied by the base and pinch feed rollers 19 and 20. In this case, upon operation of the suction brake unit 15, the trailing end side of the wrapping material in use is held by suction.
  • a joining tape piece supply unit 22 shown in Fig. 1 is operated, and the trailing end of the first wrapping material in use and the leading end of the second wrapping material A2 in a joining preparation state are joined to each other by a joining tape piece by the joining tape supply unit 22.

  • the stamper 23 can be selectively connected to a negative pressure source (not shown), and its upper surface facing up at its reset position serves as a suction surface 24.
  • a joining tape piece is supplied to the suction surface 24. More specifically, the suction surface 24 extends in a direction perpendicular to the convey direction of the wrapping material, i.e., in a direction perpendicular to the drawing surface in Fig. 1. As schematically shown in Fig.

  • the downward movement of the unrolling roller 33 can be attained since the guide roller 34 of the swing arm 31 reaches an inclined portion of the guide surface 43 of the first guide 41. Thereafter, the first guide 41 is moved upward to a predetermined position.
  • the unrolling roller 33 is moved while being in rolling contact with the joining tape T on the suction base 26, and winds the joining tape T therearound by a predetermined length, as shown in Fig. 6.
  • the stamper 23 When the unrolling roller 33 is returned to a predetermined position above the stamper 23, the stamper 23 is connected to a negative pressure source to draw the adhesive tape T on the stamper 23 by suction, and at the same time, the ratchet of the unrolling roller 33 is released.
