Definitions

  • the present invention relates to a label positioning mechanism for use with a printing machine which is operative to print the labels one by one.
  • the invention is related to a label positioning mechanism of the kind as disclosed in French patent publication 2 202 499.
  • a label positioning mechanism for use with a printing machine which is operative to print the labels one by one, which label positioning mechanism comprises: a feed wheel mounted rotatably in the body of said printing machine and formed on its circumference with the label advancing surface which is engageable with the label strip for advancing the same in a preset direction; a label positioning member connected pivotally to the body of said printing machine such that it is rotatable between a first position, where it is apart from the label advancing surface of said feed wheel thereby to form an opening inbetween, and a second position, where it is close to the same thereby to leave a clearance having a spacing substantially equal to the thickness of said label strips; a pivot axis mounted rotatably in the body of said printing machine; and an arm mechanism having its
  • This known state of the art has the disadvantage that it fails to provide a label positioning mechanism, which can bring the continuous label strip into contact with the feed wheel in a reliable manner, even with a simplified construction and which can accomplish the operations of loading and unloading the label strip onto and from the feed wheel.
  • the known label positioning mechanism provides a sliding connection between the arm mechanism and the label positioning member which fails to provide a reliable label strip pushing operation.
  • the known state of the art has the disadvantage that it fails to provide suitable means for guiding the label strip onto the feed wheel.
  • the machine body 1 is equipped with a grip 2, a hand lever 3, a printing head 4 and a not-shown printing platen, all of which are required for the printing operations.
  • the machine body 1 thus constructed has its upper center portion formed integrally with a label holder side plate 6, which in turn is equipped at its center with a core retainer 7.
  • the continuous label strip 8 is composed of a number of labels which are removably adhered to the surface of a strip of backing paper.
  • This backing paper strip is formed at preset positions with not-shown slits, which are sized to be detachably retained by the pawls 10 of a later- described feed roller 9.
  • the label holder side plate 6 is equipped at its rear end (or at the righthand side of Fig. 1) with a guide roller 11, by which the leading end of the continuous label strip 8 is guided while being retained thereon.
  • each of the upper label inlet members 12 has its upper end positioned in the vicinity of the guide roller 11 and its lower end positioned in the vicinity of the upper end portion of a guide plate 13, which will be described later.
  • the intermediate portion of each of the upper label inlet members 12 between the two ends thereof is gently curved along the outer surface of the continuous label strip 8.
  • the aforementioned guide plate 13 is made to have a generally rectangular shape and to depend from the front (which is located in the lefthand side of Fig. 1) of the lower end portions of the lower label inlet members 14. There is located at the back of the guide plate 13 a pressure tongue 16 which is hinged to depend from the lower end portions of the lower label inlet members 14. The pressure tongue 16 thus hinged is always biased by a torsion spring 17 in the direction to be brought into contact with the back of the guide plate 13.
  • an operating shaft 18 of rectangular section which is rotatably mounted to the machine body 1 by means of two rollers 18a.
  • a lock lever 19 is formed with a rectangular hole so that it is fixed therethrough to one end portion of the operating shaft 18.
  • the lock lever 19 is made to have a cylindrical main portion 20 formed in its outer circumference with an engagement notch 21, which is made into and out of engagement, by the raising and laying operations of the lock lever 19, with the engagement projection 23 of an L-shaped engagement member 22 which is fixed to the outer side of the machine body 1.
  • the upright portion 22a of the engagement member 22 is made of an elastic material so as to ensure and facilitate the engagement and disengagement between the engagement notch and projection 21 and 23.
  • a pair of operating arms 25, which are juxtaposed at a preset spacing while being connected by means of a bridge member 24, at their end portions 25a through their rectangular holes 26.
  • the other end portions 25b of the operating arms 25 are arranged before and below the operating shaft 18.
  • a pair of connecting arms 27 are pivotally connected at their one ends 27a to the other end portions 25b of the operating arms 25, respectively.
  • the arms 27 thus connected are made to depend from the other end portions 25b of the operating arms 25 and to have their other ends 27b pivotally connected to the one end 29a of a label positioning member 29 through a long pin 28.
  • there are mounted three guide rollers 30 equidistantly and rotatably on that long pin 28 so as to smooth the feed of the continuous label strip 8.
  • the aforementioned label positioning member 29 is made of a synthetic resin or the like such that it is curved along the outer circumference of the feed wheel 9, which will be described later in detail.
  • the label positioning member 29 is connected at its other end 29b to the machine body 1 pivotally by a preset angle by means of a shaft 31.
  • the center portion of the label holding member 32 is exposed to the outside through an aperture 33 which is formed in the label positioning member 29.
  • a . pair of widthwise regulating side plates 34 are formed to depend from both side edges of the label positioning member 29 so as to regulate the widthwise play of the continuous label strip 8.
  • the label positioning member 29 thus constructed is brought to approach and leave the feed wheel 9 of cylindrical shape through the continuous label strip 8.
  • the feed wheel 9 is mounted to the machine body 1 by means of a shaft 36 such that it can be turned a preset pitch by the manual squeezing action of the hand lever 3 of the machine body 1.
  • the outer circumference of the feed roller 9 acts as a label advancing surface which is formed equidistantly with a number of the pawls 10 in the circumferential direction of the feed wheel 9.
  • a pair of torsion springs 38 are wound on the center portion of the aforementioned operating shaft 18 such that they have their one ends 38a retained on the upper edges of the operating arms 25 and their other ends 38b retained on the upper edge of the bridge member 24.
  • the both operating arms 25 are always biased to rotate counter-clockwise about the operating shaft 18, as viewed in Fig. 2.
  • the label positioning member 29 is biased to rotate clockwise about the shaft 31 by the actions of the operating arms 25 so that it is pushed onto the label advancing surface 35 of the feed wheel 9.
  • FIG. 1 shows the condition, under which the lock lever 19 is at its raised position so that its engagement notch 21 is in engagement with the engagement projection 23 of the engagement member 22.
  • the operating arms 25 have their other ends 25b held before and above their one ends 25a
  • the label positioning member 29 has its one end 29a held at the upper limit of its rotations so that it establishes an open space together with the label advancing surface 35 of the feed wheel 9.
  • the continuous label strip 8 which is held on the core retainer 7, is unrolled therefrom so that its leading end is inserted by way of the guide roller 11 into the clearance 15 between the upper and lower label inlet members 12 and 14 and further advanced along these members 12 and 14.
  • the label strip 8 thus advanced brings its leading end into abutment against the rear surface of the guide plate 13, where it turns its advancing direction so that its leading end can proceed between the guide plate 13 and the pressure tongue 16. Since, in this instance, the pressure tongue 16 is urged forward by the action of the torsion spring 17, the leading end of the label strip 8 is guided, while running on the upper surface of the pressure tongue 16, into the opening which is formed between the label positioning member 29 and the feed wheel 9. Then, the label strip 8 is advanced along the label advancing surface 35 of the feed wheel 9 until it is fed to the outside from between that surface 35 and the other end 29b of the label positioning member 29.
  • the aforementioned lock lever 19 is laid down so as to release the engagement between the notch 21 and the projection 23. Then, the operating shaft 18 is turned counter-clockwise, as viewed in Fig. 1, and the operating arms 25 are accordingly turned counter-clockwise about the operating shaft 18. It should be noted here that the rotations of the operating arms 25 can take place promptly and smoothly because the biasing forces of the torsion springs 38 act in the direction to promote the rotations of the operating arms 25.
  • the connecting arms 27 are moved downward in accordance with the rotations of the operating arms 25 so that the label positioning member 29 is turned clockwise, as viewed in Fig. 1, about the shaft 31 until it pushes the continuous label strip 8 in position onto the label advancing surface 35 of the feed wheel 9, as can be seen from Figs. 2 and 3.
  • the pushing operation of the label positioning member 29 can be accomplished reliably because the biasing forces of the torsion springs 38 act to bias the connecting arms 27 downwardly, as viewed in Fig. 2, through the operating arms 25.
  • the feed wheel 9 is turned a preset pitch so that the continuous label strip 8 can be fed in a desired direction by the actions of the pawls 10 on the feed wheel 9.
  • the label strip 8 as a whole can be taken out of the machine body 1 by way of that opening, the pressure tongue 16, the guide plate 13 and the clearance 15 between the inlet members 12 and 14 in the order recited.
  • the label positioning member is urged toward the feed wheel by the biasing forces of the elastic members, the continuous label strip never fails to be pushed onto the feed wheel so that it can be fed without fail in accordance with the rotations of the feed wheel.
  • the label positioning member is made capable of approaching and leaving the label advancing surface of the feed wheel, the loading and unloading operations of the label strip onto and from the feed wheel can be accomplished easily and promptly.
  • This advantage can be reflected by the case, in which the labels are peeled off from their backing strip and adhered to the feed wheel or the like. Even in this case, those labels can be removed without any difficulty.
  • the major components of the label positioning mechanism of the present invention are five, namely, the label positioning member, the arm mechanism, the operating shaft, the elastic member and the feed wheel.
  • the number of parts required is relatively small for the label positioning mechanism of this kind, while simplifying the construction, so that the label positioning mechanism of the invention is suitable for mass production.
