  By the way, when the label-forming base material M is thick and stiff, it does not matter so much. However, in recent years, the thickness of the label has been reduced from the viewpoint of reducing the material cost, etc. If the thin and thin waist, the label-forming substrate M delivered by the delivery roller 51 may cause a jam at the cutting and conveying unit 52, and the thin and thin label-forming substrate M is cut and conveyed. There is a problem that smooth and reliable supply to 52 is not possible. Even in the case of the label forming substrate M to which the heat-sensitive adhesive is applied, even if it is thick, a slight adhesive force is generated by the clamping pressure of the delivery roller 51, and it is easy to bend at the delivery roller 51 portion. There is also a problem.

The substantially U-shaped shaping portion 31 having a pair of inner corner portions ic, ic provided at a distance shorter than the width of the label forming substrate M, and the label forming base curved by the shaping portion 31 In order to fix the shape holding portion that holds the curved shape of the label forming base material M and the shaping portion 31 to the support plates 11 and 11 of the frame 10 by being along the both side portions of the material M, the shaping portion 31 is screwed. The shape holding portion is constituted by the lower end portions of the base material shape holding guides 40 and 40 screwed to the shaping portion 31.

  A plurality of guide pieces 31a project from the curved surface of the curved label-forming base material M on the shaping portion 31, and the central portion in the width direction extends along the curved label-forming base material M. The amount of protrusion of the guide piece 31a is the largest, and the amount of protrusion gradually decreases toward both sides in the width direction.

  The base material shape retention guide 40 is a bar-shaped member having a pentagonal cross section. As shown in FIGS. 6 to 9, in the downstream base material shaping member 30 portion, the label forming base material M curved by the shaping portion 31 is used. A label forming base that is curved by the downstream base material shaping member 30 and the upstream base material shaping member 50 along both side portions and between the downstream base material shaping member 30 and the upstream base material shaping member 50. An inclined guide surface 41 that supports both sides of the material M is provided.

  As shown in FIGS. 6 and 7, the upstream-side base material shaping member 50 is basically composed of a pair of inner corner portions and a plurality of internal corner portions that are the same components as the shaping portion 31 of the downstream-side base material shaping member 30. The shaping part 51 which has the guide piece 51a and curves the label forming base material M in the width direction by bringing both side edges in the width direction of the label forming base material M into contact with the pair of inner corners, and this shaping The closing plate 52 screwed to the shaping portion 51 and the curve of the label forming substrate M so that the center portion in the width direction of the label forming substrate M curved by the portion 51 is sandwiched with a slight gap. A shape holding portion for holding the shape, and the shape holding portion is configured by upper end portions of the base material shape holding guides 40 and 40 inserted into the fitting space formed by the shaping portion 51 and the closing portion 52. Has been.

  Cylindrical stoppers 42 and 42 are attached to the upper ends of the base material shape holding guides 40 and 40, and upstream base material shaping members fitted into the upper end portions of the base material shape holding guides 40 and 40. Positioning of the upstream side base material shaping member 50 is performed by the lower end edge of the 50 closed portions 52 coming into contact with the stoppers 42 and 42 of the base material shape holding guides 40 and 40.

  The blocking plate 52 has protrusions 52a at positions corresponding to the guide pieces 51a formed at the center in the width direction of the shaping portion 51 and at positions inside the guide pieces 51a and 51a adjacent to the guide pieces 51a. Are formed, and the shape of the label-forming base material M when the label-forming base material M is introduced is determined by the guide pieces 52a and the guide pieces 51a of the shaping portion 51.

  In order to assemble the downstream-side base material shaping member 30, the base material shape holding guide 40, and the upstream-side base material shaping member 50 configured as described above to the frame 10 on which the delivery roller 20 is supported, Then, the base material shape holding guides 40, 40 whose lower ends are screwed to the downstream side base material shaping member 30 are inserted into the space outside the clamping portions 21a, 22a of the driving roller 21 and the driven roller 22, and the downstream side After the mounting plate 32 of the base material shaping member 30 is screwed to the support plates 11, 11 of the frame 10, the upstream side base material shaping member 50 is moved from the upper side of the frame 10 to the upper ends of the base material shape holding guides 40, 40. It should just fit in.

  As described above, the label base material delivery unit 2 is provided with the downstream side base material shaping member 30 and the upstream side base material shaping member 50 disposed on the downstream side and the upstream side in the delivery direction of the delivery roller 20, respectively. The forming base material M is curved in the width direction, and the center portion of the curved label forming base material M in the width direction is sandwiched between the sandwiching portion 21a of the driving roller 21 and the sandwiching portion 22a of the driven roller 22, and the sending roller A label curved on the guide surface 41 of the base material shape holding guides 40 and 40 disposed between the downstream base material shaping member 30 and the upstream base material shaping member 50 disposed above and below the substrate 20. Since the curved shape of the label forming base material M is maintained by keeping both sides of the forming base material M along, even the thin label forming base material M having no waist has a pseudo waist. Can be Moreover, since the waist can be maintained to some extent, the cutting and conveying means 3 installed between the delivery roller 20 and the downstream base material shaping member 30 or downstream of the label base material delivery unit 2. The thin-walled label-forming base material M does not generate jam at this portion, and can be sent to the cutting and conveying means 3 in a stable state. This is particularly effective in the case of a thin label-forming substrate M having a thickness of 30 to 50 μm.

  Further, in order to prevent the jamming before the fed label-forming base material M reaches the cutting and conveying means 3 installed on the downstream side, a belt mechanism that keeps the label-forming base material M in the meantime. In order to prevent the label forming base material M from jamming at the cutting and conveying means 3 part, a complicated mechanism is installed such that the leading end of the label forming base material M is sucked and sent while being pulled. Therefore, the structure becomes simple and the manufacturing cost of the thermal labeler 1 can be reduced.

  Since the label forming substrate M is pulled by the delivery roller 20 and the label forming substrate M does not jam on the upstream side of the delivery roller 20, the upstream substrate is located upstream of the delivery roller 20 in the delivery direction. It is not necessary to provide the shaping member 50. However, if the upstream side substrate shaping member 50 is also arranged on the upstream side in the delivery direction of the delivery roller 20 as in the label substrate delivery unit 2, the label is formed first. When setting the base material M through the label base material delivery unit 2, the setting operation can be easily performed.

Since this label base material sending unit 2A also has the same structure as the above-described label base material sending unit 2 in the frame and the sending roller portion, the same components are denoted by the same reference numerals and the description thereof is omitted. The downstream side base material shaping member 60 </ b> A, the upstream side base material shaping member 60 </ b> B, and the base material shape holding guide 70 having different configurations will be described in detail.

  The downstream-side base material shaping member 60A and the upstream-side base material shaping member 60B have the same configuration, and each has a shaping roller 62 rotatably supported by a pair of opposing support plates 61 and 61, and a shape retention. Two pairs of rollers including rollers 66 are provided. The downstream base material shaping member 60A has a mounting plate 60Aa screwed to a pair of opposing support plates 61, 61. As shown in FIG. 11, the mounting plate 60Aa is attached to the support plate 11, 11 is screwed.

  As shown in the figure, the shaping roller 62 includes a fixed shaft 63 screwed to a pair of opposing support plates 61 and 61, and a pair of roller bodies 64 and 64 that are rotatably fitted to the fixed shaft 63. And a coil spring 65a that is inserted into the fixed shaft 63 and urges the pair of roller bodies 64, 64 away from each other, and is fixed between the support plates 61, 61 and the pair of roller bodies 64, 64. It is composed of a spacer 65b fitted around the shaft 63, and a slight gap is formed between both roller bodies 64, 64.

  The roller main body 64 includes a main body portion 64a having a tapered shape on the support plate 61 side, and a flange portion 64b projecting outward in the radial direction that is connected to the small diameter end of the main body portion 64a. A concave portion 64c for accommodating the coil spring 65 is formed at the large-diameter end facing the roller body 64.

  As shown in the figure, the shape maintaining roller 66 includes a fixed shaft 67 screwed to a pair of opposing support plates 61, 61, a roller body 68 rotatably fitted on the fixed shaft 67, and a support. The spacers 69 are fitted on the fixed shaft 67 between the plates 61 and 61 and both ends of the roller body 68.

  The roller body 68 includes a small-diameter portion 68a at the center in the width direction corresponding to the large-diameter portions of the main-body portions 64a and 64a of the shaping roller 62, and the shaping roller 62 connected to both ends of the small-diameter portion 68a. The main body portions 64a and 64a are formed of a tapered taper portion 68b corresponding to the tapered taper portion, and the shaping roller 62 and the shape are formed so that a slight gap is formed between the main body portion 64a of the shaping roller 62. An installation interval with the holding roller 66 is set.

  Therefore, when the label forming substrate M is passed between the shaping roller 62 and the shape maintaining roller 66, both side edges in the width direction of the label forming substrate M are wrinkles in the roller body 64 of the shaping roller 62 as shown in FIG. By abutting against the inner surface of the portion 64b, the label forming substrate M is curved in the width direction along the main body portions 64a and 64a of the roller main body 64.

  As shown in FIGS. 13 and 14, the base material shape holding guide 70 is formed at both ends on a pair of opposing support plates 61 and 61 of the downstream base material shaping member 60 </ b> A and the upstream base material shaping member 60 </ b> B. By fitting into the connecting hole, the connecting rod 71 that connects the downstream side base material shaping member 60A and the upstream side base material shaping member 60B, and the cross-section substantially fixed to the central portion in the length direction of the connecting rod 71 As shown in FIG. 16, the guide main body 72 is formed between the downstream base material shaping member 60A and the upstream base material shaping member 60B, as shown in FIG. It has the inclined guide surface 72a which supports the both sides of the label forming base material M curved by the base material shaping member 60A and the upstream side base material shaping member 60B.

  In order to assemble the downstream base material shaping member 60A, the base material shape holding guide 70, and the upstream base material shaping member 60B configured as described above to the frame 10 on which the delivery roller 20 is supported, Thus, the base material shape holding guides 70 and 70 having the lower ends of the connecting rods 71 and 71 attached to the downstream base material shaping member 60A are inserted into the space outside the holding portions 21a and 22a of the drive roller 21 and the driven roller 22. Then, after the attachment plate 6Aa of the downstream side base material shaping member 60A is screwed to the support plates 11 and 11 of the frame 10, the upstream side base material shaping member 60B is moved from the upper side of the frame 10 to the base material shape holding guide 70, What is necessary is just to insert in the upper end part of 70 connecting rods 71 and 71. FIG.

  As described above, the label base material sending unit 2A is also provided with the downstream side base material shaping members respectively disposed on the downstream side and the upstream side in the sending direction of the sending roller 20, similarly to the label base material sending unit 2 described above. The label forming base material M is curved in the width direction by 60A and the upstream side base material shaping member 60B, and the center part in the width direction of the curved label forming base material M is sandwiched by the sandwiching portion 21a of the driving roller 21 and the driven member. The base material shape holding guide is sandwiched between the downstream base material shaping member 60 </ b> A and the upstream base material shaping member 60 </ b> B which are sandwiched by the sandwiching portion 22 a of the roller 22 and arranged vertically with the delivery roller 20 interposed therebetween. Since the curved shape of the label forming base material M is maintained by arranging both sides of the curved label forming base material M along the guide surfaces 72a of 70 and 70, a thin label with no waist is provided. Even if it is the forming base material M, the waist can be given in a pseudo manner, and the waist can be maintained to a certain extent, so that the space between the feed roller 20 and the downstream base material shaping member 60A The thin-walled label-forming substrate M is not jammed in the portion of the cutting and conveying means 3 installed on the downstream side of the label substrate feeding unit 2, and is sent to the cutting and conveying means 3 in a stable state. be able to.

  Similarly to the above-described label base material delivery unit 2, the label base material delivery unit 2A is also provided with the upstream side base material shaping member 60B on the upstream side in the delivery direction of the delivery roller 20, so that the label first is labeled. When the forming base material M is set through the label base material delivery unit 2, the setting operation can be easily performed.

  Further, in the label base material delivery unit 2A, as described above, the pair of roller bodies 64 and 64 that are rotatably fitted to the fixed shaft 63 are urged in a direction away from each other by the coil spring 65a. Therefore, by adjusting the thickness of the spacer 65b, it is possible to adjust the gap between the roller bodies 64, 64, that is, the interval between the flange portions 64b, 64b of the roller bodies 64, 64. Even if the width slightly changes, it can be dealt with, and the effect that the mold can be easily changed is obtained.

  In each of the above-described embodiments, the upstream base material shaping members 50 and 60B are disposed on the upstream side in the delivery direction of the delivery roller 20, but the present invention is not limited to this. The downstream side base material shaping members 30 and 60A may be provided on the downstream side in the delivery direction. However, as described above, by providing the upstream side base material shaping members 50 and 60B, the initial setting operation of the label forming base material M becomes easy. Therefore, it is preferable to provide the upstream side base material shaping members 50 and 60B. desirable.

Although the side base material shaping member 50 has been described, the present invention is not limited to this, and the shaping parts 31 and 51 are divided into two in the width direction in the same manner as the shaping roller 62 of the label base material delivery unit 2A described above. By adopting a configuration capable of approaching and separating, it is possible to cope with a change in the width of the label forming substrate M.

  Further, in each of the above-described embodiments, the label base material feeding unit mounted on the thermal labeler in which the heat-sensitive adhesive label is sequentially attached so as to be wound around the outer peripheral surface of the body of the dry battery has been described. Of course, the film delivery unit of the present invention can be mounted on various apparatuses for delivering a belt-like film, and it is needless to say that the film delivery unit is particularly effective when delivering a thin belt-like film having no waist.

  It can be used as a film delivery unit that is mounted on a labeler or the like that sequentially sticks the label to an adherend while forming a label of a predetermined length by sequentially cutting the long strip of film.
