- the hand lever 8 When the printing operations of the labels 60 of the label strip L is to be performed, the hand lever 8 is squeezed toward the grip lever 2 so that the head carrying lever 3 is turned downward about the pivot pin 4. In response to the downward rotation of the head carrying lever 3, the inking roller 7 is brought to turn on the type bearing surface of the printing head 6 so as to supply the same with ink. As i the squeezing operation of the hand lever 8 further proceeds, the printing head 6 is finally brought into abutment contact with one of the labels 60, which have been fed onto the printing platen 41 by that time, so that the printing operation is effected with its type bearing surface.

Abstract
Description
- The present invention relates to a label printing and applying machine of portable or desk type, and particularly to a clogging preventive device for preventing the label printing and applying machine from being clogged with labels. More particularly, the present invention relates to a label printing and applying machine of the above type for preventing such a printing platen of the label printing and applying machine, which is made responsive to the squeezing operation of a hand lever toward a grip lever to feed a continuous label strip composed of a series of self-adhesive labels carried through an adhesive upon a strip of carrier paper onto the printing platen, as is made operative to print and guide the continuous label strip, with the labels due to the adhesive which frequently flows out of the side edges of the label strip. ;
- Conventionally, the printing platen of that type is constructed to have its upper surface formed with a guide recess, which is sized to have substantially the same width as that of the continuous label strip so as to guide the same while continuously contacting with the both side edges of the label strip.
- In case, however, the label printing and applying machine of that type is used in summer in the tropics or in an area of higher temperature than a proper level, or in case the storing condition of the continuous label strip is bad, the adhesive will frequently flow out of the both side edges of the label strip until it sticks to the printing platen. As a result, the adhesive will further stick to the both guide walls defining the guide recess of the printing platen so that it provides an obstacle against the forward movement of the label strip.
- If the adhesive having stuck to the guide walls grows a lump of the adhesive, the continuous label strip fails to be held in a horizontal position upon the printing platen thereby to form a raised portion, thus deteriorating the resultant printing effects.
- On the other hand, moreover, there is stored in the label guide recess of the printing platen a label residue such as label chips which are produced when the cuts and perforations of the labels and carrier paper are formed in the label strip. The label residue thus produced will also provide an obstacle against the movement of the label strip.
- It is therefore ah object of the present invention to provide a clogging preventive device for use with a label printing and applying machine, which device is free from those drawbacks concomitant with the prior art.
- Another but major object of the present invention is to provide a clogging preventive device of the above type, which is operative to eliminate the troubles, which might otherwise take place at the printing platen due to the adhesive of the labels and the label residue, thereby to ensure the smooth feed of the continuous label strip.
- According to a major feature of the present invention, there is provided a clogging preventive device for use with a label printing and applying machine including a printing platen for guiding a continuous strip of labels, in which a series of self-adhesive labels are carried on a strip of their carrier paper by means of an adhesive, wherein the improvement comprises: a pair of juxtaposed label guide walls formed to longitudinally extend at the both sides of said printing platen; and label relief means for receiving the continuous label strip so that at least the both label side portions may be prevented from contacting with said label guide walls.

- Fig. 9 is an enlarged perspective view showing a continuous strip label, in which self-adhesive labels and their carrier paper are adhered temporarily.
- Before entering into the detailed description of the clogging preventive device according to the present invention, a. label printing and applying machine of portable type will be generally described with reference to Figs. 1 and 2 in case it is equipped with the clogging preventive device.
- As shown, a
head carrying lever 3 composed of a pair of side plates is arranged to have its trailing end hinged by means of a pivot pin 4 to an upper trailing end portion of a pair of machine frames 1 such that it is biased upward or clockwise by the biasing force of areturn spring 5 at all times. A printing head 6 is carried on the leading end portion of thehead carrying lever 3. Indicated at reference numeral 7 is an inking roller which is operative to apply ink to the type bearing surface of the printing head 6. Ahand lever 8 to be manually squeezed toward and released from a grip lever 2 is made integral with thehead carrying lever 3. - As can be better seen from Fig. 2, a
feed roller 17 for feeding a continuous strip of labels L is formed on its circumference with two rows of radial feed teeth 9 and 10, a pressure groove 18 defined between the feed teeth 9 and 10, and a one-way clutch 20. Thefeed roller 17 thus formed is mounted on itsshaft 21 which in turn is piv- otted to the machine frames 1. With close reference to Figs. 1 and 2, to the side plate 11 depending from the lower rear portion of the afore-mentionedhead carrying lever 3, there is hinged aratchet pawl 12 which is biased to rotate counter-clockwise of Fig. 1 by the biasing force of atorsion spring 14. Indicated at reference numeral 16 is a ratchet wheel which can engage with theratchet pawl 12 in response to the releasing operation of thehand lever 8 so as to turn thefeed roller 17 intermittently by one pitch between the adjacent feed teeth 9 and 10. - Turning now to Fig. 3, there is hinged to the feed roller 17 a
printing platen 40 which forms a part of the clogging preventive device according to the present invention. This detail will be described later, and short discussion is made in the following. Theprinting platen 40 is arranged between the paired machine frames 1 and formed with aplaten surface 41 of such a recessed cross-section as is formed with a pair of juxtaposedlabel guide walls 42 which are formed slightly higher than the thickness of the continuous label strip L. Theprinting platen 40 thus arranged and formed is made to have a knife edge shape at its leading end. The trailing end of theprinting platen 40 is extended to form a pair ofarm plates 43 at its both sides. Below thearm plates 43, there are formed a pair ofshaft holes 44, in which theshaft 21 of thefeed roller 17 is fitted. Incidentally, there are mounted to the arm plates 43 a pair of connectingmembers 45 which in turn are hinged to a later-describedlabel holding member 26 by means of apin 27. - Reverting to Fig. 1, a pair of
label holding members 38 forming accessory parts of the clogging preventive device of the present invention are composed of shelf-shaped beams which are made to extend inwardly of the machine frames 1. Thelabel guide walls 42 of the afore-mentionedprinting platen 40 are made to abut against the lower sides of thelabel holding members 38, thus forming such athin passage 39 as to barely admit the continuous label strip L. - There is arranged above the afore-mentioned feed roller 17 a
label holding member 26 of an arcuate shape which is elastically biased toward thefeed roller 17 by means of aspring member 24. Thelabel holding member 26 is formed at its front back side with an abutment surface, which is in abutment contact with the upper sides of thelabel guide walls 42 of the afore-mentionedprinting platen 40, thus forming a label feed passage 22 which is slightly thicker than the continuous label strip L. - On the other hand, a
bottom cover 28 located below the machine frames 1 is constructed to have its leading end hinged to the machine frames 1 by means of apivot pin 29 such that it can be opened clockwise and its trailing end retained on the machine frames 1 by means of alocking device 30. Thebottom cover 28 has its center portion made integral with a carrierpaper guide member 31, which in turn has its inclined carrierpaper receiving surface 32 positioned below the leading end portion of the afore-mentionedlabel holding members 38, thus forming apeeling turning portion 33 of a restricted clearance between the carrierpaper receiving surface 32 andlabel holding members 38. On the other hand, a carrierpaper holding spring 24a is forced into engagement with the pressure groove 18 which is formed between the feed teeth 9 and 10 carried on thefeed roller 17. In front of theprinting platen 40, there is located alabel applying device 36 which is supported pivotally on apivot pin 35 in the vicinity of alabel outlet 34. Above the machine frames 1, moreover, there is located alabel roller holder 37 which is used to hold the continuous label strip L stored in the rolled shape. - Turning to Fig. 9, the continuous label strip L to be used with the clogging preventive device according to the present invention is composed of a series of self-
adhesive labels 60 and a strip ofcarrier paper 61 carrying thelabels 60 through an adhesive 62 which is applied to the backs of thelabels 60. - With closer reference to Fig. 9, in order that the label strip L can be advanced by its engagement with the feed teeth 9 and 10 of the
feed roller 17, thebacking paper strip 61 is formed with a series ofperforations 64 at such positions as correspond to thecuts 63 formed between anyadjacent labels 60a peeled from thebacking paper strip 61. In order to facilitate the separation of thelabels 60a having theadhesive 62, moreover, a parting agent such as silicone oil is applied to the surface of the backing paper strip 16. Incidentally, the both side portions La of the label strip L are used merely to illustrate theside edges 65,lower side portions 65 andupper side portions 67, as is also shown in Fig. 4. - In order to enable the clogging preventive device of the present invention to be understood more, the printing and feeding operations of the continuous label strip L thus prepared will be generally discussed in the following.
- When the printing operations of the
labels 60 of the label strip L is to be performed, thehand lever 8 is squeezed toward the grip lever 2 so that thehead carrying lever 3 is turned downward about the pivot pin 4. In response to the downward rotation of thehead carrying lever 3, the inking roller 7 is brought to turn on the type bearing surface of the printing head 6 so as to supply the same with ink. As ithe squeezing operation of the hand lever 8 further proceeds, the printing head 6 is finally brought into abutment contact with one of thelabels 60, which have been fed onto theprinting platen 41 by that time, so that the printing operation is effected with its type bearing surface. - On the other hand, the feeding operation of the label strip L is performed by releasing the squeezed
hand lever 8. During this release, the label strip L engaging with the feed teeth of thefeed roller 17 at the upper circumference thereof is fed by the intermittent rotation of thefeed roller 17. As a result, the printedforemost label 60a is advanced upon theprinting platen 41 to the leading end thereof. At the afore-mentionedpeeling turning portion 33, theforemost label 60a thus advanced is peeled from thecarrier paper 61 due to its own rigidity by the turning action of a small loop of thecarrier paper 61 formed. In the meantime, on the other hand, thecarrier paper 61 is advanced along the lower side of the printing platen in the backward direction of the hand labeler until it restores its engagement with the feed teeth 9 and 10 of thefeed roller 17 at the lower circumference thereof so as to effect its tensile action. - Incidentally, the
label 60a thus peeled is prepared by the pushing actions of both thelabel holding members 38 arranged above theprinting platen 41 and the carrierpaper receiving surface 32 formed below theprinting platen 41. After having been separated from thecarrier paper 61, theforemost label 60a is adhered to a commodity or the like by means of thelabel applying device 36. - The clogging preventive device according to the present invention will now be described in detail with reference to Figs. 4 to 8.
- A first embodiment of the clogging preventive device of the present invention is shown in Figs. 4 and 5, in which
printing platen 40 is formed, according to a first feature of the present invention, with alabel receiving recess 46 having a larger width b than that a of the continuous label strip L. As shown, thelabel receiving recess 46 is defined between thelabel guide walls 42 which are juxtaposed widthwise of theprinting plate 41 and is made to extend longitudinally thereof. As a result, the label side portions La, more specifically, theside edges 65 of the label strip L can be prevented from contacting with thelabel guide walls 42, thus leaving bothside clearances 47 inbetween. - According to a second feature of the present invention, there are formed in the upper surface of the printing platen 41 a pair of elongated
label relief grooves 48 which are arranged at the both side corners of the afore-mentionedlabel receiving recess 46 and which are cut deeper than therecess 46. As a result, the bothlower side portions 66 of the label strip L can be prevented from contacting with thelabel receiving recess 46. - According to a third feature of the present invention, moreover, the
label holding members 38, which are arranged above theprinting platen 41 in a manner to extend from the machine frames 1, are formed at their lower sides with a pair of elongatedlabel relief grooves 38a which correspond to the afore-mentionedlabel relief grooves 48, and at its inner lower side with a label guide surfaces 38b which will contact with the label strip L. As a result, the both upper side portions of the label strip L can be prevented from contacting with thelabel holding members 38. - These
label holding members 38 are used in the label peeling system thus described in the fore-going embodiments, in which the continuous label strip L is subjected to the pushing and pulling actions. However, thelabel holding members 38 can be dispensed within the system, in which pins are provided either at the leading end or in the longitudinal direction of theprinting platen 41 so that the labels may be peeled from the label strip L by pulling thecarrier paper 61 only. - According to a fourth feature of the present invention, still moreover, in case the
printing platen 41 has its upper surface formed with thelabel receiving recess 46 which has the larger width b than that a of the continuous label strip L, this label strip L may meander while being advanced because its side portions La are prevented from contacting with thelabel guide walls 42. As a countermeasure of this trouble, the printing platen is formed at its lower side with a carrierpaper guide recess 50 which has the same width as that of thecarrier paper 61 separated from thelabels 60. As a result, the label strip L can be advanced straight as a whole upon theprinting platen 41. - According to a fifth feature of the present invention, still moreover, both of the
label relief grooves 48 formed in the longitudinal direction of theprinting platen 41 are formed with two series of throughslots 49 which are arranged at a suitable spacing from one another. As a result, the residue of the labels such as their chips, which might otherwise drop down upon theprinting platen 41 from the continuous label strip L so that it is stored thereon, can be discharged to the outside through the through holes 49. Incidentally, the label residue is produced, when thecuts 63 connecting temporarily the lables 60a of the label strip L and theperforations 64 of their carrier paperl,61 are formed, and is stuck to the label strip L. - The second embodiment of the present invention is shown in Fig. 6, in which the
printing platen 40 has also itsupper platen surface 41 formed with thelabel receiving recess 46 having the larger width b than that a of the continuous label strip L similarly to the first embodiment and having a flattened label sliding surface. Moreoever, thelabel receiving recess 46 is formed also at its both side corners with two series of the throughholes 49, which are arranged at a suitable spacing in the longitudinal direction so as to permit the discharge of the label residue. Theprinting platen 41 is also formed at its lower side with the carrierpaper guide recess 50 for thecarrier paper 61. - According to the third embodiment of the present invention shown in Fig. 7, the
printing platen 41 having a similar construction to the first embodiment is formed with two series oflabel guide projections 51 which project from thelabel guide walls 42 so as to guide the label strip L in a discontinuous manner. Thelabel guide projections 51 thus formed are arranged to face each other at a spacing equal to the width a of the label strip L so that they can contact with the side edges 65 of the label strip L thereby to stabilize the forward movement of the same. - In the fourth embodiment shown in Fig. 8, the
printing platen 41 having a similar construction to the second embodiment is formed with thelabel guide projections 51 which also project from thelabel guide walls 42 so as to guide the label strip L in a similarly discontinuous manner. - As has been described hereinbefore, the clogging preventive device according tolthe present invention has the fore-going constructions so that it can enjoy the following advantages:
- (1) Since the label receiving recess which is formed in the upper surface of the printing platen between the juxtaposed label guide walls is made to have a larger width than the continuous label strip, this label strip can be prevented from having its both side edges contacting with the label receiving recess while being advanced. As a result, even if an adhesive flows out of the both side edges of the label strip, in which the labels are temporarily adhered to the carrying paper by means of the adhesive, it can be prevented from being stuck to the label guide walls so that the smooth label feed can be ensured to prevent the clogging with the adhesive with the resultant satisfactory printing effects.
- (2) Since the afore-mentioned label receiving recess is formed at its both side corners with two rows of longitudinal label relief grooves, even both the lower side portions of the label strip can be prevented from contacting with the label receiving recess. As a result, the adhesive can be effectively prevented from being stuck.
- (3) Since, still moreover, the label holding members arranged above the printing platen are formed with a pair of elongated label relief grooves, the label strip is forced into contact with the upper surface of the printing platen so that the both upper side portions of the label strip can be prevented from contacting with the
label holding members 38, in the case of the label peeling system in which the label strip is subjected to the pushing and pulling actions. As a result, the adhesive can be further effectively prevented from being stuck. - (4) Since, still moreover, the printing platen is formed at its lower side with a carrier paper guide recess which has the same width as that of the carrier paper of the label strip, the label strip can be advanced straight as a whole by the carrier paper being guided in its guide recess even if the label strip is not guided upon the- upper surface of the printing platen.
- (5) Since, still moreover, either the label relief grooves or label relief recess of the printing platen are formed at their both side corners with two series of through slots, the label residue which might otherwise be left on the platen, can be discharged to eliminate the label troubles.
