Description

Technical Field

[0001] The present invention relates to a fishing rod having a characteristic handle for holding and retaining and a method for forming the handle of the fishing rod. Background Art

[0002] In the past, a handle was provided at the base end of a fishing rod. Usually, the handle is formed by attaching another flexible component to the outer peripheral surface of the rod, but such a handle can also be formed by printing. When the handle is formed by printing, it is necessary to form it so that it is not easy to slip when gripped or held and has a good grip.

[0003] As a method of forming a grip by printing, there is known a method using screen printing as disclosed in Patent Document 1. Also, Patent Document 2 is known to use a transfer sheet having a printing ink layer and an adhesive layer.

[0004] Patent Literature

[0005] Patent Document 1: Japanese Patent Publication No. 4-59857

[0006] Patent Document 2: Japanese Patent Application Laid-Open No. 7-298808 Summary of the invention

[0007] In the past, when a grip is formed on the surface of a pole by printing as described above, various problems have arisen. In the screen printing disclosed in Patent Document 1, it is difficult to print thicker, and Figure 7 As shown, the printed portion has a sharp edge 90a of a raised printed portion (convex portion) 90 formed on the surface 80A of the rod 80. In addition, since the convex portion is raised by multiple screen printings, it is difficult to perform accurate alignment, which is not practical. In addition, using a transfer sheet as in Patent Document 2 only costs the cost of the sheet. In addition, since the sheet member is bonded to the circumferential surface, the adhesion will be reduced depending on the bonding conditions.

[0008] In addition, although it is known that an inkjet printer is used as a method for printing on the surface of a fishing rod, it is generally believed that this printing method is used to form patterns and text. Figure 7 As shown, if the edge 90a of the printed portion 90 is not sharp as much as possible (the edge 90a is formed to be substantially right angle), the pattern and text will become blurred and the visibility will be poor. That is, in inkjet printing, the corner is made as sharp as possible to improve the visibility.

[0009] Furthermore, since it is not preferred to weight the fishing rod, the height (thickness) of the protrusion is not considered to be sufficient. According to the grip evaluation conducted by the inventors, when the height is not at least 80 μm, it cannot be felt as a handle, and the anti-slip effect is also insufficient. When printing on the rod using an existing inkjet printer, the formation of a handle with a protrusion of such a height is not considered.

[0010] That is, when the grip of the fishing rod is formed by printing, the height of the printed convex portion and the shape of the surface have not been sufficiently studied, so that a good grip is not achieved and an anti-slip effect cannot be obtained.

[0011] The present invention is an invention focusing on the above-mentioned problems, and the technical problem to be solved is to provide a fishing rod and a method for forming the handle of such a fishing rod, which has a good grip and a non-slip effect when a handle is formed on the fishing rod using an inkjet printer.

[0012] In order to achieve the above-mentioned purpose, the fishing rod of the present invention is a fishing rod in which a convex portion constituting a handle is formed on the surface of the rod by an inkjet printer, and is characterized in that the convex portion is printed by multiple overlapping coatings so that its thickness is greater than 80 μm, and its surface is leveled so that there are no edges.

[0013] As described above, since the handle has a convex portion formed by inkjet printing and the height of the convex portion is 80 μm or more, it is easy to catch the palm and fingers when holding it, and a non-slip effect can be obtained, thereby improving the operability of the fishing rod. In addition, since the surface of the convex portion is flattened, there is no corner on the surface, so the grip is good.

[0014] In addition, the present invention is a method for forming a grip by printing a convex portion on the surface of a pole using an inkjet printer, comprising:

[0015] Step 1, an ink coating step of causing the head of the inkjet printer to scan in the axial direction of the rod while rotating the rod to discharge ultraviolet curing ink onto the surface of the rod;

[0016] and step 2, after applying the ink, performing an ultraviolet curing step of curing the ink by UV irradiation,

[0017] The rotation speed of the rod in step 1 is 90 to 360 rpm, and the viscosity of the ink is 10.5±1.0 mPa·s (45° C.).

[0018] The UV irradiation in step 2 is performed 0.01 to 0.03 seconds after the ink is ejected, and the peak intensity of the UV irradiation is 700 mW / cm 2 ~950mW / cm 2 ,

[0019] The steps 1 and 2 are repeated to perform overlapping coating so that the thickness of the protrusions becomes 80 μm or more.

[0020] By combining the above conditions, i.e., the rotation speed of the rod, the viscosity of the ink, the time from ink adhesion to UV irradiation, the UV irradiation intensity, and overlapping coating (printing by rotating the rod multiple times), the centrifugal force acting on the rod and the above conditions can form a flat convex portion. That is, according to such a printing method, a grip that is easy to hold in the palm of the hand when held, can obtain a non-slip effect and a good grip can be obtained.

[0021] According to the present invention, a fishing rod having a good grip and an anti-slip effect and a method for forming a handle of the fishing rod can be obtained by using an inkjet printer. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] Next, a fishing rod and a method for forming a handle thereof according to the present invention will be described with reference to the drawings.

[0032] Figure 1The fishing rod 1 shown is, for example, a pull-out fishing rod, which includes a first rod section 3 and a plurality of intermediate rods 5 and a rod tip section 7 (the number of rods connected is arbitrary) that can be stored in the first rod section 3. At this time, the fishing rod can be a plug-in type, a sleeve type, etc., or a fishing rod with a reel seat and a fishing line guide and a reel installed.

[0033] As is well known, each rod is formed by winding a fiber reinforced resin material (FRP; prepreg), and a handle 10 having a convex portion is formed on the surface (material surface) of the first rod section 3 according to a printing method described later.

[0034] The handle 10 is formed by using an ultraviolet curing ink (hereinafter also referred to as UV ink) on an inkjet printer and printing it in the gripping and holding area of ​​the rod. UV ink can use colorless (transparent ink), colored (color ink), metallic ink with a glittering color, and is applied to the surface of the first section of the rod according to a predetermined printing pattern. In this case, a convex portion with a certain height can be formed by continuously overlapping the UV ink. In addition, since a thermal curing process is required after coating, thermal curing inks cannot be applied in an overlapping manner, and therefore a sufficient height cannot be ensured.

[0035] Figure 2 It is a schematic diagram of an inkjet printer 50 for forming a convex portion, and the convex portion constitutes the handle 10 of the first section of the rod 3. The inkjet printer 50 used in the present invention comprises: a head 51, which has a nozzle for discharging UV ink 30 and moves back and forth in a scanning direction (the axial direction of the first section of the rod) through a slide; and a light source 52 for UV curing, which is arranged at a position different from the setting position of the slide (a position opposite to 180° in the figure).

[0036] When a convex portion is formed on a tubular body such as the first rod section 3 by using an inkjet printer 50 as in the present invention, the two ends of the first rod section 3 are fixed, and the head 51 of the inkjet printer is scanned in the axial direction of the first rod section 3 while rotating it, and the amount of droplets of UV ink 30 ejected from the nozzle, the ejection position, and the amount of irradiation light of the light source 52 for curing ultraviolet rays, the irradiation time, the time until irradiation, etc. are controlled according to the shape of the convex portion formed on the surface. That is, the UV ink 30 attached to the surface of the first rod section 3 is cured by the light source 52 and fixed in this state. In the present embodiment, a transparent ink of one color is used, and thus the ejection nozzle is configured to control the ejection of one color while the head 51 is scanning.

[0037] In the above-mentioned inkjet printing, the shape of the convex portion formed on the surface of the first section of the rod can be adjusted by controlling the viscosity of the ejected UV ink, the rotation speed of the first section of the rod, the time until the leveling treatment is performed (the time until the UV ink is attached, the droplets are expanded by the centrifugal force acting on the first section of the rod, and the time until the droplets are cured by light irradiation), and the irradiation intensity of the light source. At this time, if the amount of UV ink ejected from the ejection nozzle is controlled, the density of the ink (ink concentration) attached to the surface in a dotted state can be changed. Specifically, when the ink concentration is high, the surface tends to become flat during leveling, and when the ink concentration is low, tiny bumps and depressions tend to be generated on the surface during leveling, thereby changing the reflective state (sparkling).

[0038] like Figure 2 As shown, when an inkjet printer is used to eject droplets of UV ink from the ejection nozzle, they will adhere to the surface of the first section of the rod 3 (exaggerated representation of the attached droplets 30A). At this time, since the droplets will solidify immediately if light is immediately irradiated in the attached state, it is difficult to level them by the centrifugal force exerted by the rotation of the first section of the rod. In other words, each convex portion cannot form a fully leveled shape (curved smooth surface), causing the edge portions to become sharp. In contrast, by attaching ink of a specified viscosity (ink with transferability), adjusting a specified rotation speed and the time until light irradiation, and irradiating light at a specified intensity, the attached ink can be transferred and solidified.

[0039] That is, Figures 2 to 4 As shown, by controlling the viscosity of the UV ink, the rotation speed of the first section of the rod 3 after the ejected ink droplets 30 adhere, and utilizing the centrifugal force, the adhered droplets 30 can be diffused along the surface 3A, and by irradiating the diffused droplets with light of a specified intensity, a leveled convex portion (a convex portion 35 that protrudes from the surface and has no edges) can be formed.

[0040] In this case, in order to form a grip 10 with a good grip and a non-slip effect, the inventor conducted experiments under various conditions. When printing is performed by inkjet printing, the convex portion 35 that can achieve the above-mentioned effect can be formed by printing under the following conditions.

[0041] (1) About speed

[0042] Regarding the rotation speed of the first section of the rod, although it also depends on the parameters of the inkjet printer used, when the rotation speed is too fast, the attached droplets are easy to fly away, and when the rotation speed is too slow, it is impossible to obtain a sufficient centrifugal force effect. Here, considering the viscosity of the UV ink used, the rotation speed of the first section of the rod is set to 90-360rpm (this rotation speed is within the range that can be covered by a normal inkjet printer). In addition, this range is also due to the change in the diameter of the first section of the rod for printing.

[0043] (2) Regarding the viscosity of UV ink

[0044] Regarding the viscosity of the ink, although it is set in relation to the rotation speed of the first rod section, if the first rod section is rotated within the above range, the viscosity of the ink only needs to be 10.5±1.0 mPa·s (45°C). That is, it is sufficient to use UV ink of a viscosity that allows the UV ink to spread and flow by centrifugal force before being cured by the light source 12.

[0045] (3) Time until UV irradiation

[0046] As described above, since the leveling effect of the centrifugal force acting on the first section of the pole cannot be fully obtained when the light source is set on the carriage and cured at the same time as the UV ink is ejected, the ink is not cured at the same time as it is attached. Specifically, considering the rotation speed and the viscosity of the UV ink, the irradiation is performed 0.01 to 0.03 seconds after the ink is ejected.

[0047] (4) Peak intensity of UV irradiation

[0048] If the UV light from the light source is too weak, sufficient curing will not be achieved, so a certain level of irradiation intensity is required. By setting the peak intensity of UV irradiation at 700mW / cm 2 ~950mW / cm 2 Within the range of , sufficient curing effect can be obtained in a leveling state.

[0049] (5) Regarding the thickness of the formed protrusions

[0050] Regarding the thickness (height) T of the convex portion 35, in order to form a grip 10 with a good grip and a non-slip effect, it is preferably ensured to be 80 μm (0.08 mm) or more. At this time, since the convex portion 35 with a thickness of about 0.02 to 0.03 mm can be formed by one printing when the convex portion is formed under the above conditions, at least three overlapping coatings are performed. At this time, if Figure 4As shown, in one printing, a so-called substantially semicircular (arc-shaped) surface without edges can be formed on the convex portion 35, and even if overlapping coating is performed thereon, the thickness increases in the same shape. That is, even if overlapping coating is performed three or more times, a handle 10 composed of concave and convex portions (the surface of the concave portion is the surface of the first section of the rod) with a predetermined thickness and no edges can be formed.

[0051] In addition, in general printing methods (screen printing, etc.), overlapping coating cannot be performed at the same position. On the contrary, by performing inkjet printing as in the present invention, the attachment position of the UV ink can be controlled, so the desired concave and convex shape can be easily and quickly formed. In addition, although there is no restriction on the thickness of the convex portion 35, it is preferably less than 150 μm in consideration of processing time, stability, etc.

[0052] Figure 5 FIG. 1 is a diagram showing an example of the grip 10 after the protrusions 35 are formed by the above-mentioned printing method.

[0053] Although various convex parts 35 (concave parts 35a) can be formed by inkjet printing, in this example, the convex parts formed on the surface are formed into a honeycomb pattern of adjacent polygons. That is, since the hexagonal part is formed as the convex part 35 and the boundary line is the honeycomb pattern of the concave part 35a (unprinted part), the convex part 35 with a predetermined height in the axial direction, the circumferential direction and the inclined direction is easy to be caught when holding and holding, so that a grip structure with a good grip and a high anti-slip effect can be obtained. In addition, although the honeycomb pattern is made into a hexagon in the drawings, it can also be composed of a pentagon, an octagon, etc.

[0054] Figure 6 This is a diagram showing another example of a handle in which convex portions are formed by the above-mentioned printing method.

[0055] Although Figure 5 The structure shown is the same, and in this example, a honeycomb pattern is formed on the surface, but the outline portion (dividing line portion) of the hexagon is a convex portion 35, and the inside of the hexagon is a concave portion 35a (a portion not printed).

[0056] Thus, by using inkjet printing, a flat convex (concave-convex) pattern can be easily formed. Therefore, a grip with a good grip and a high anti-slip effect can be easily formed without installing soft parts as in the prior art.

[0057] The convex portion 35 formed as described above can also be printed on the surface 3A of the FRP material. In this case, since the concavoconvex is produced by the fibers on the surface, the anchoring effect between the printed convex portion can be improved, so that the convex portion is not easy to peel off. Alternatively, by performing a base treatment on the surface of the material to form a base layer (coating a primer, etc. or grinding to form grinding ribs on the surface, etc.), the adhesion strength of the UV ink can be improved so that the convex portion is not easy to peel off. In particular, if the surface 3A is a curved surface formed by a tubular body, the attached impurities can be removed by grinding and the anchoring effect can be improved, so that a stable convex portion can be formed.

[0058] In addition, it is preferred that a protective film of a transparent layer (including a color transparent layer) is pre-formed on the surface of the formed protrusion 35. Such a transparent layer may be formed by applying a UV curable transparent ink as it is after the protrusion is formed by the inkjet printing, or may be formed separately by transparent coating or the like.

[0059] By forming such a protective film, the surface of the protrusion 35 can be protected, and Figure 6 In the case where the width of the convex portion is narrow as shown, it is possible to effectively prevent breakage, chipping, etc. In addition, the three-dimensional effect can be enhanced by the prism effect.

[0060] Although the embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit and scope of the present invention.

[0061] Although the handle formed by inkjet printing is illustrated by the first section 3 in the above embodiment, it can also be applied to other than the first section. For example, on a casting rod or a large fishing rod for a boat, there is a case where a handle is formed on a portion other than the first section. Therefore, if the handle is formed by Figure 1 In the fishing rod shown in the figure, there is a case where a handle is set at the tail, top and middle part of the middle rod 5 to prevent slipping. The above-mentioned inkjet-printed handle can also be formed in a specified area on this rod.

[0062] In addition, for substrate treatment, various color patterns (including multi-color or transparent) can be formed on the surface of the material by surface treatment such as printing, coating, electroplating, etc. In addition, for surface grinding, grinding ribs can be formed with directionality, or grinding ribs can be formed with random concave and convex.

[0063] Furthermore, as for the convex portion 35, as long as it is not easy to slip and has a good grip, its shape (pattern) is not limited. Since the anti-slip effect can be obtained if the directions of the formed convex portions are directed in different directions, for example, the convex portions directed in multiple directions can be formed into a grid-like pattern, or a large number of convex portions can be formed, or different convex portion shapes and thicknesses can be combined to perform appropriate deformation. In addition, as long as there is no discomfort in the grip, the leveling can also have some concave and convex on the surface of its convex portion.
