Definitions

  • the present invention relates to a portable label applying system, which is equipped with a printer, a cassette for taking up a continuous web of printed labels, and a label applicator adapted to be charged with the cassette and to be manually actuated to peel the labels from their backing paper and to apply them to commodities, and more particularly to an automatic label winding and charging device for use in the portable label applying system.
  • the printing head for the bar codes necessarily has its size made larger than that for the usual characters because of their standardized size.
  • the hand labeler is accordingly large-sized and heavy for easy handling so that it augments the fatigue of its operator.
  • the bar codes are required to have check digits, but the hand labeler finds it difficult to have a function to automatically compute the check digits because it is restricted in size and structure. As a result, the check digits have to be separately computed and set in the printing head, thus making the hand labeler inconvenient in this respect.
  • Another but specific object of the present invention is to provide an automatic label winding and charging device which can automatically wind a web of printed labels upon a cassette and charge a label applicator with the cassette.

  • the upward bent portion 119a has its intermediate portion fitted in the cam hole 123 of a locking member 122.
  • the cam hole 123 has its one side edge composed of a stepped cam portion 123a for regulating the lock position and a stepped cam portion 123b for regulating the release position, and the two cam portions 123a and 123b are joined through a sloped portion 123c.
  • a label guide 124 is formed, as shown in Fig.
  • the label guide 124 has its lower end extending outside of the bent portion lllb of the lock lever 111 and below the lower side of the lock lever 111.
  • a connecting bar 125 which extends between the link 114 and the guide pin 106.
  • the connecting bar 125 has its one end hingedly connected through a ball. joint 126 to the end portion of the actuating lever 119 opposite to the knob 121 and its other end fixed to the side of the label guide 124.
  • the connecting bar 125 is so guided by two pairs of guide rollers 127, 128, 129 and 130 that it can conduct linear motions.
  • a guide bar 131 which has its one end fixed to the label guide 124.
  • the guide bar 131 is also so guided by guide rollers 132, 133, 134 and 135 that it can conduct linear motions.
  • the guide rollers 127 to 130 and 132 to 135 thus far described are attached to a bracket 136 which is fixed on the base frame 90.
  • the guide rollers 127 to 130 and 132 to 135 may be grooved or not or may be combined.
  • a guide member 137 which draws a large arcuate curve.
  • This guide member 137 is fixed to either the base frame 90 or the bracket 136 and has its leading end leading to the vicinity of the upper end of the opening of_the leading end of the frame 7 of the cassette 1.
  • a peel preventing member 138 Inside of the guide member 137, there is disposed a peel preventing member 138.
  • This member 138 is such a block as has its side edge curved to profile the guide member 137 to define inbetween a guide groove 139. In order to clean this guide groove 139 or to prevent the same from being jammed with the label or labels, incidentally, it is preferred to make removable at least one of the guide member 137 and the peel preventing member 138.
  • This peel preventing member 138 is shaped to complement the side edge of the leading end side of the cassette 1 and is formed in its midway with a projection. 138a which is to be fitted in the notches 7d formed in the leading end of the cassette 1. The reason why the peel preventing member is so highly curved is intended to prevent the labels from being peeled off their backing paper if the label web is guided in an acutely bent shape.
  • an empty cassette 1 is set on the frame 90 of the printer 3 by making use of the lock levers 110 and 111.
  • the rotary member 12 of the cassette 1 is turned clockwise of Fig. 1 to its open position.
  • the actuating lever 119 is turned clockwise of Fig. 7 around the pin 120, by manually pinching the knob 121, to move its bent portion 119a from the cam portion 123a to the cam portion 123b of the locking member 122.
  • the link 114 and the connecting bar 125 are pushed upward of F ig. 7 to push the label guide 124 and to turn the lock levers 110 and 111 clockwise around the pins- 112 and 113, respectively.
  • the bent portion 110a of the lock lever 110 and the bent portion lllb of the lock lever 111 are respectively turned apart from the head 109 of the rotary shaft 108.
  • the cassette 1 can be mounted on the bracket 136 above the base frame 90.
  • the cassette 1 is brought onto the bracket 136 with its open rotary member 12 being positioned at the side of the actuatinq lever 119 and with its backing paper guide groove 15 being directed toward the label guide 124.
  • the guide pins 106 and 107 are fitted in the positioning holes 7a of the cassette 1.
  • the projection 138a of the peel preventing member 138 is fitted in the notches 7d formed in the side edges of the leading ends of the cassette 1.
  • the cassette 1 should be erroneously set with the rotary member 12 being left unopened, this setting is impossible because the rotary member 12 has its label holding portion 13 closing the notches 7d.
  • the bent portions 110a and llla of the lock levers 110 and 111 are positioned apart from the recesses 7c and 7d of the cassette 1 so that they provide no obstruction to the mounting operation of the cassette 1.
  • the actuating lever 119 is turned coounter-clockwise around the pin 120 to have its bent portion l19a fitted on the stepped cam portion 123a. Then, the link 114 and the connecting lever 125 are pulled downwardly of Fig. 10 so that the label guide 124 is pulled toward the cassette 1 whereas the lock levers 110 and 111 are turned counter-clockwise. As a result, the upper end portion 124a of the label guide 124 comes into the backing paper guide groove 15 of the cassette 1, as shown in Fig. 12, to leave a such a gap from the bottom plate 14 as to guide the continuous label web 4. By the counter-clockwise turn of the lock lever 110, moreover, the bent portion 110a is fitted in the notches 7d of the cassette 1.
  • the bent portion llla is fitted in the recess 7c of the cassette 1 by the counter-clockwise turn of the lock lever 111.
  • the engagement tongues 25 at the lower end of the knob 24 are pushed by the bent portion lllb located at the outer side of the lock lever 111 so that the pressure member 20 enters against the elastic force of the spring 26 thereby to disengage its needle 23 from the backing paper guide groove 15.
  • the cassette 1 is reliably locked by the lock levers 110 and 111.
  • the not-shown keyboard of the printer 3 is used to input the bar codes which are desired to be printed.
  • the continuous label web 4 having the non- printed labels is pulled out of the reel 91 along the guides 93 and 94 through the position detecting mechanism 95 acting as another label guide and is turned along the platen 97 until its leading end is guided into the gap between the label guide 124 and the bottom plate 14 of the cassette 1.
  • the heat transfer ink ribbon 100 is also pulled out of the reel 99 and is guided along the guide rollers 101 and 102 and between the thermal head 96 and the label web 4 until its leading end is taken up by the take-up reel 1 105 through the guide rollers 103 and 104.
  • a not-shown motor is energized to turn the rotary shaft 108 so that the take-up core 8 starts its rotations through the boss 11 of the cassette 1, in which the head 109 of the shaft 108 is fitted.
  • the platen 97, the take-up reel 105 and so on are started to rotate so that the thermal head 96 is operated to start the printing operations of the bar codes in response to the set printing instructions.
  • the continuous label web 4 having bar codes heat-transferred to its labels is ' advanced continuously or consecutively intermittently through the label guide 124.
  • the label web having left the label guide 124 is advanced along the guide member 137 to the cassette 1 by way of the guide groove 139 extending between the guide member 137 and the peel preventing member 138. Since, at this time, the rotary member 12 of the cassette 1 is opened, as shown in Fig. 5, the label web 4 is guided along the lower side of the label holding portion 13 into the winding space 8c defined by the rotary member 12 and the take-up core 8. Since the winding space 8c is counter-tapered by the inner faces of the flanges 8a and 8a of the take-up core 8, the label web 4 is guided for a while between the flanges 8a and 8a without being dragged by their inner faces.
  • the label web 4 is guided along the guide spring 9 to the take-up core 8 until it is thrusted onto the take-up core 8 by the leading end of the guide plate 9. At this time, the label web 4 is in the state in which both its side edges contact with the straight core body 8b at the legs of the flanges 8a and 8a. Since the straight core body 8b has a width slightly smaller than that of the label web 4, this web 4 has both its side edges restricted, when it is pushed onto the take-up core 8 by the guide spring 9, by the core body 8b so that it is wound or taken up sequentially as the take-up core 8 is turned.
  • the not-shown motor is stopped to interrupt the supply or let-off of the label web.
  • a cutter C interposed between the platen 97 and the label guide 124 may be operated to cut the label web.
  • the cassette 1 on which the label web having the bar codes printed is wound in the predetermined quantity is demounted from the printer.
  • the actuating lever 119 is turned clockwise, as viewed in Fig. 10, to unlock the cassette 1 from the lock levers 110 and 111, and the label guide 124 is disengaged from the cassette bottom plate 14 to release the cassette 1 from any restriction.
  • the cassette 1 can be easily removed if it is manually disengaged from the guide pins 106 and 107.
  • Two or three sheets of the labels 6 are peeled from the bottom plate 14 of the removed cassette 1, and the rotary member 12 is returned to the locked state of Fig. 1, .thus finishing the charging operations of the cassette 1 with the labels 6.
  • the cassette 1 thus having been charged with the printed labels is attached to the label applicator 2 in the following manners. Specifically, the mounting portions 31 of the cassette 1 are accommodated in the accommodating space 34 of the applicator 2 such that the engagement projections 30 at the leading end of the cassette 1 are held in engagement with the engagement notches 37 of the applicator 2. At this time, the pent-roofs 77, which are formed below the display label fitting recesses 32 of the cassette 1, are placed on the ledges 35 of the applicator 2 so that the cassette 1 is automatically locked by the lock mechanism 67.
  • the aforementioned engagement projections 73 drop while turning the lock member 69 counter-clockwise against the biasing force of the spring 68.
  • the backing paper 5 is released from being held by the pressure land 22 and the needle 23 of the pressure member 20 so that it is smoothly fed back until it is discharged to the outside of the label applicator 2.
  • the push-up plate 60 is retracted to disengage its lower face from the supporting member 62.
  • the pressure member 20 is moved down to restore its original position, while pushing down the push-up plate 60 counter-clockwise, by the force of the spring 26, so that the backing paper 5 is held again by the coactions of the pressure land 22 and the needle 23.
  • the label web 4 since the label web 4 has its advancing position regulated to a horizontal position, only the backing paper 5 'is .
  • the push-up plate 60 abuts against the supporting member 62 to turn the same counter-clockwise because the force of the spring 26 to push down the push-up plate 60 is stronger than the summation of the forces of the springs 64 and 65. Then, the push-u p plate 60 advances sliding on the lower faces of the tongues 25 but not raising the same. As a result, the backing paper 5 is fixed by the pressure member 20 and is not returned to the front by the forward motion of the pawl member 46.
  • this pawl member 46 has its advancing pawls 45 disengaged from the cuts 78 of the backing paper 5 and is turned clockwise against the action of the spring 59 to slide on the lower side of the backing paper 5 until it restores its original position, in which it engages again with the cuts 78 of the backing paper 5.
  • the demounting button 70 is pushed foward, as shown in Fig. 25.

  • the pressure member 20 is moved down to restore its original position so that the backing paper 5 is held again by the coactions of the pressure land 2-2 and the needle 23.
  • the push-up plate 60 is set to advance while sliding on the lower faces of the tongues 25 but not raising the same.
  • the backing paper 5 is fixed by the pressure member 20 and is not returned to the front by the forward motion of the pawl member 46.
  • this pawl member 46 has its advancing pawls 45 disengaged from the cuts 78 of the backing paper 5 to slide on the lower side of the backing paper 5 until it restores its original position, in which it engages again with the cuts-78 of the backing paper 5.
  • the demounting button 70 is pushed forward. Then, the lock member 69 is turned counter-clockwise to disengage its lower end corner 71 from the engagement projections 73 of the cassette 1, and the rear portion of the cassette 1 is slightly popped up by the spring action of the backing paper holding member 74, which presses the lower side of the backing paper 5 in front of the backing paper guide groove 15, so that the cassette 1 can be easily removed by the single action.
  • the label web having its labels printed with the bar codes can be automatically wound over a predetermined length merely by charging the printer with the cassette so that the troublesome work of winding the labels upon the cassette can be eliminated to ensure efficient operations.
  • the operation of mounting the cassette in the printer can be conducted by the single action of actuating the actuating lever, but the labels are not peeled off while the label web is being taken up, because the printer is equipped with the peel preventing member.
  • Figs.56 to 58 show another example of use of the present invention.
  • the take-up cassette 1 and the label applicator 2 are not used, but the printed labels 6 are manually applied to the commodities.
  • the example is constructed of an adaptor 1200 and a take-up tool 1201, as shown in Fig. 56.
  • the adaptor 1200 is constructed such that a cylindrical shaft 1203 protrudes from the center of a rectangular base plate 1202.
  • the shaft 1203 is formed with a blind bore 1205 which extends from the base plate 1202 and which has grooves 1204.
  • These grooves 1204 and the blind boref205 are so shaped as can fit therein the head 1122 of the rotary shaft 1121 of the printer 3.
  • the axial length of the shaft 1203 is made larger than the width of the label web 4.
  • the take-up tool 1201 is formed into such a shape as has a generally C-shaped section having a slit 1206 by axially cutting the outer circumference of a cylinder.
  • the take-up tool 201 is made of a flexible material such as metal or plastics.
  • the take-up tool 1201 is made to have an internal diameter slightly smaller than the external diameter of the shaft 1203 and to have an axial length equal to that of the shaftf203.
  • the adaptor 1200 is fitted on the head 1122 of the rotary shaftf121 of the.printer 3.
  • the keyboard 1146 of the printer 3 is used to input the bar codes to be printed.
  • the continuous label web 4 is printed with the bar codes, and the leading end of the printed label web 4 is threaded through the gap formed between the guide portion 120 and the label guide 1143.
  • the keyboard 1146 is used to temporarily interrupt the operations of the printer 3.
  • the take-up tool 1201 is mounted on the outer circumference of the shaft 1203 by expanding its internal diameter. Then, the take-up tool 1201 is held in close contact upon the outer circumference of the shaft 1203 by its own flexibility. Thus, the leading end portion of the label web 4 is inserted into the inside of one end portion 1207 of the take-up tool 1201. As a result, that leading end portion is clamped and held between the take-up tool 1201 and the shaftf203. If, in this state, the keyboard 1146 of the printer 3 is used to restart the printer 3, the printed label web 4 is let off, and the adaptor1200 is turned clockwise so that the label web 4 is taken up on the take-up tool 1201.
  • the cutter mechanism 1118 is actuated to cut the trailing end of the label web 4.
  • the take-up tool 1201 is removed from the shaft 1203. More specifically, the end portion of the take-up tool 1201 at the side where the label web 4 is not wound is gripped and pulled sideway. Then, the take-up toolf201 is slid on the outer circumference of the shaft 1203 so that it is removed from the. shaftf203 together with the printed label web 4 in the rolled shape. If the outer circumference of the take-up tool 1201 is pinched by the fingers, as shown in Fig.
  • the tool 1201 is warped inwardly so that only the tool 1201 can be pulled out of the rolled label web 4 if it is pulled to the side of the Operator.
  • the take-up tool 1201 thus removed can be reused for taking up the subsequent label web 4 if it is set on the adaptor 1200 of the printer 3 likewise the procedures explained in the above.
  • the aforementioned rolled label web 4 itself is brought to a commodity counter or warehouse, in which the labels 6 are manually peeled from the backing paper 5 and applied to the target commodities.
  • the using example of the present invention is composed of the adaptor 1200 and the take-up tool 1201 both having the simple constructions.
  • the label web 4 can be simply taken up and taken out from the printer 3 by the single action after the taking-up operation.
  • the take-up tool 1201 can be simply extracted by its own flexibility from the rolled label web 4.
  • the present using example need not use the take-up cassette 1 and the label applicator 2 of the foregoing embodiment.
  • the portable label applying system becomes so inexpensive that it can be employed at a reasonable cost even by stores which handle a relatively small number of labels.
  • the label web having its labels printed with the bar codes can be automatically wound while automating the setting of the backing paper in the bottom of the cassette.
  • the label web having been wound up can be cut to have a predetermined length, thus making it possible to provide an automatic label winding and charging device which has a small number of parts and a simple construction.
