  • GLASS BULB BLOWING MACHINE Inventors: Noboru Inoue, Funabashi-shi; Makoto Wada, Kawasaki-shi, both of Japan Assignee: Tokyo Shilbaura Denki Kabushiki Kaisha a/k/a Tokyo Shibaura Electric (10., Ltd., Kanagawa-ken, Japan Filed: July 23, 1969 Appl. No; 844,036
  • ABSTRACT A glass-bulb-blowing machine including a plurality of interconnected orifice plate supporting link units, comprising a baseplate. Each orifice plate is removably connected to one end of the baseplate by means of a projection and opening connection and locked in position by means of a sliding member.
  • the sliding member is mounted on the one end of the baseplate and springs urge it into locking engagement with the orifice plate.

  • This invention relates to a glass-bulb-blowing machine of the so-called ribbon machine type and more particularly to improved means for removably supporting orifice plates.
  • each orifice plate is removably connected to one end of a base plate of each orifice plate supporting link unit by suitable connecting means, such as a pin and opening connection, and locked in the connected position by means of a sliding member which is normally urged toward the orifice plate into locking engagement therewith.
  • suitable connecting means such as a pin and opening connection
  • FIG. I is a plan view of an orifice plate supporting link unit constructed in accordance with this invention.
  • FIG. 2 is a front elevation of the orifice plate supporting link unit shown in FIG. 1;
  • FIG. 3 is a side view, partly in section, of blow head links cooperating with the orifice plates.
  • an orifice plate supporting link unit 1 comprising a horizontal base or support plate 2, and locking means comprising a slidable plate member 3 slidable along a guideway defined by the base plate 2 and a cover plate 4 secured to the base plate for releasably locking an orifice plate 9 in a predetermined fixed position.
  • the sliding plate 3 is continuously biased into a locking position by a pair of compression springs S and its fore or leading lower edge is slanted as at 6.
  • Pins 7 or projections are secured to the base plate 2 near its free end and extend through mounting openings of the orifice plate 9 with its fore end 8 slanted to cooperate with the slanted leading end 6 of the slidable or sliding plate 3.
  • the slanted portions 6 and 8 comprise inclined mating surface portions and cooperate together when the slidable plate 3 is in its locking position to releasably lock the orifice plate in its fixed position.
  • the slidable plate member 3 is also provided with a lip portion (not numbered) projecting towards the orifice plate 9 and engageable therewith to increase the locking effect of the inclined mating surfaces.
  • the orifice plate 9 is provided with a glass-bulb-blowing opening or orifice 11 and the orifice plate supporting link unit 1 with guide rollers 12 and I3 cooperating with a rail 14 having a L-shaped cross section.
  • each one of the blow head links 15 which are connected together to form an endless chain is provided with a bushing 16 to slidably receive a sleeve 17 which is normally urged upwardly by means of a compression spring 18.
  • the sleeve 17 accommodates a blow pipe 19 which is normally biased downwardly by means of a compression spring 20.
  • the blow pipe 19 is provided at its lower end with a blow tip 22 adapted to engage a glass ribbon 21 from which glass bulbs are to be blown through openings 11 of the orifice plates 9 and at its upper end with a blow shoe 24 adapted to slidably engage a liner 23 at the bottom of an air tank (not shown).
  • Cam rollers or followers 25 and 26 are mounted respectively on one side of the sleeve 17 and the blow pipe I9 to be operated by cams (not shown) such that blow shoe 24 is brought to engage liner 23 before blow tip 22 engages the glass ribbon 21 thus ensuring a supply of air blow at the time when the blow tip 22 and glass 21 are brought into positive engagement.
  • a bulb 27 is blown beneath each opening 11 of the orifice plate, the configuration of the bulb being determined by the mould, not shown.
  • the sliding plate 3 is retracted against the bias of springs 5 to disengage slants the inclined mating surface portions 6 and 8 and then orifice plate 9 is raised to disengage it from the pins 7 thus removing the orifice plate from the base plate.
  • each of said orifice plate supporting link units comprises a base plate, a sliding member slidably mounted on one end of said base plate, an orifice plate removably connected to said one end of said base plate, and means urging said sliding member into locking engagement with said orifice plate.
  • an orifice plate In a glassbulb-blowing apparatus: an orifice plate; a support plate member; means removably mounting said orifice plate in a fixed position on said support plate member; and locking means for releasably locking said orifice plate in said fixed position on said support plate member comprising a slidable plate member slidable into and out of a locking position, means on said slidable plate member coacting with said orifice plate for releasably locking said orifice plate in said fixed position when said slidable plate member is in said locking position, means mounting said slidable plate member for sliding movement on said support plate member into and out of said locking position, and means continuously biasing said slidable plate member into said locking position; whereby sliding movement of said slidable plate member out of said locking position allows said orifice plate to be readily removed from said support plate member and easily replaced by another.
  • a glass bulb blowing apparatus according to claim 4; wherein said means on said slidable plate member coacting with said orifice plate comprises inclined mating surface portions on said slidable plate member and said orifice plate engageable together when said slidable plate member is in said locking position to releasably lock said orifice plate in said fixed position and disengageable from each other when said slidable plate member is out of said locking position.
  • a glass-bulb-blowing apparatus according to claim 5; wherein said slidable plate member includes a lip portion projecting outwardly from the slidable plate member inclined surface portion towards said orifice plate and overlying a surface portion of said orifice plate when said inclined mating surfaces are engaged to effectively increase the locking effect.
  • a glass-bulb-blowing apparatus according to claim 4; wherein said means mounting said slidable plate member for sliding movement comprises a cover member connected to said support plate member and defining therewith a guideway, and wherein said slidable plate member has an end portion slidable along said guide way into and out of said locking position 8.
  • a glass-bulb-blowing apparatus according to claim 7; wherein said means continuously biasing said slidable plate member comprises spring means disposed along said guideway continuously urging said slidable member into said locking position.
  • a glassbulb-blowing apparatus comprising means defining mounting openings in said orifice plate, and projections on said support plate member each releasably and snugly engaged within respective ones of said mounting opening thereby defining said fixed position of said orifice plate.
  • a glass-bulb-blowing apparatus according to claim 9; wherein said means on said slidable plate member coacting with said orifice plate comprises inclined mating surface portions on said slidable plate member and said orifice plate engageable together when said slidable plate member is in said locking position to releasably lock said orifice plate in said fixed position and disengageable from each other when said slidable plate member is out of said locking position.
