It is desirable to have a roller having an information storage medium capable of efficiently performing quality control, inventory management, etc. even when repeatedly exposed to a high temperature, high pressure, and high humidity environment. The roller of the present invention is characterized by comprising: a core material having a storage portion; an information storage medium stored in the storage portion; and a cover member formed of a cured product of a thermosetting resin and provided on the upper portion of the information storage medium stored in the storage portion in a manner to block an opening of the storage portion.
Description
Technical Field
The present invention relates to a roller including an information storage medium for efficiently performing quality control, inventory control, and the like.
Among them, the present invention relates to a technique for enabling a roll having an elastomer coated on a core material to achieve high efficiency in quality control, inventory control, and the like.
Among them, the present invention relates to a technique for improving efficiency of quality control, inventory control, and the like by using an elastic roll (for example, a rubber roll, a urethane roll, or a sponge roll) formed (coated) with an elastomer by vulcanization and curing. In other words, the present invention relates to a technique for enabling an elastic roller repeatedly exposed to high temperature, high pressure, and high humidity during manufacturing, use, maintenance (re-coating), and the like to achieve high efficiency in quality control, inventory control, and the like.
Background
In the process of manufacturing, processing, and transporting a sheet-like product such as a steel sheet, paper, or film, a large number of rolls are used. The roller is often used in a severe environment, and is periodically replaced because of the consumption and deterioration caused by load, heat, chemical liquid, oil, and the like. In addition, when sudden breakage or trouble occurs during use, the roller is replaced. Therefore, in order to cope with such a failure, a plurality (hundreds) of rolls are stored and managed in a factory.
In particular, in the roller, the use of an elastic roller in which an elastic body is coated on a core material causes the coated elastic body to be consumed, degraded, or broken. Thus, with respect to the elastic roller, the manufacturer of the elastic roller represented by the applicant of the present application retrieves the used elastic roller for maintenance and delivers it to the factory used. In maintenance, in many cases, the worn, deteriorated or broken old elastomer is removed to re-coat the new elastomer, and the new elastomer is delivered to a factory to be used. Therefore, the elastic roller is stored and managed not only in a factory but also in a manufacturer of the elastic roller during the conveyance process.
In addition, conventionally, the storage and management of these large numbers of rollers are performed by printing roll information such as numbers and marks on the end surfaces of the core material and identifying (visually confirming) the marks.
However, this method has a problem that it is difficult to recognize engraved roll information due to a severe environment (load, heat, chemical liquid, oil, etc.) in use. In particular, there are also rollers that are replaced every few years, and this problem is more pronounced with such rollers.
As a technique for replacing the imprinting, a technique of attaching or embedding an information storage medium such as a bar code or an IC tag, to which roll information is input, in a core material to store and manage the information storage medium has been proposed (patent documents 1 and 2).

Problems to be solved by the invention
However, in the inventions described in patent documents 1 and 2, there is a problem that the information storage medium peels off or falls off during use or maintenance of the roller, or communication failure is caused by the environment at the time of use or maintenance.
In particular, when the roller is an elastic roller such as a rubber roller, a urethane roller, or a sponge roller, vulcanization and curing are performed at the time of recoating the elastomer, and this problem becomes more remarkable. That is, since the information storage medium is repeatedly exposed to high temperature, high pressure, and high humidity in the vulcanizing step and the curing step every time the re-coating is performed on the elastic roller such as the rubber roller, the urethane roller, or the sponge roller, there is no problem in the re-coating for 1 or 2 times, and if the number of re-coatings increases, there are problems such as peeling, detachment, and communication failure of the information storage medium.
In addition to the above-described problems, the roller information management member described in patent document 2 has a problem that an error (human error) occurs during installation because the roller information management member is manually installed on a roller to be managed.
Therefore, in rolls (particularly, elastic rolls) used in factories, quality control and inventory control using information storage media are hardly performed, and in the present situation, control by imprinting is also generally performed.
The present inventors have conducted intensive studies and as a result, have found the following findings: by providing the housing portion having the opening in the core material of the roller, the information storage medium is housed in the housing portion, and further providing the cover member formed of the cured product of the thermosetting resin so as to close the opening of the housing portion on the upper portion of the information storage medium housed in the housing portion, quality control, inventory control, and the like of the roller can be efficiently performed even if a commercially available general-purpose information storage medium is used. In other words, the following findings were obtained: by providing the same or corresponding specific technical features (STF: SPECIFIC TECHNICAL Feature) as those of the core material provided with the storage portion, the information storage medium, and the cover member formed of the cured product of the thermosetting resin, quality control, inventory control, and the like of the roller can be efficiently performed even when a commercially available general-purpose information storage medium is used.
In addition, the following findings were obtained: this "same or corresponding Specific Technical Feature (STF)" is particularly useful in the case where the roller is an elastic roller such as a rubber roller, a urethane roller, a sponge roller, or the like. Namely, the following findings were obtained: even when the information storage medium is repeatedly exposed to high temperature, high pressure and high humidity, the information storage medium is not peeled off, separated or communication failure is not caused, and quality control, inventory control and the like can be efficiently performed by using a commercially available general-purpose information storage medium.
Further, the following findings were obtained: whether or not the information storage medium can pass the high-temperature high-pressure high-humidity test under the specific conditions can be used as a criterion for determining whether or not the information storage medium can be used in the present application.
The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a roller capable of efficiently performing quality control, inventory control, and the like using a commercially available general-purpose information storage medium.

The roller of the present invention is characterized in that the information storage medium is bonded in the housing portion by a thermosetting resin.
Effects of the invention
According to the roller of the present invention, the housing portion having the opening is provided in the core material of the roller, the information storage medium is housed in the housing portion, and the cover member formed of the cured thermosetting resin is provided so as to cover the housing portion in the upper portion of the information storage medium housed in the housing portion, whereby the roller can be realized in which inventory management, quality management, and the like can be performed even when the roller is exposed to an environment of high temperature, high pressure, and high humidity at the time of manufacturing, use, and maintenance (at the time of re-coating). Such a roller can be realized by using a commercially available general-purpose information storage medium.
Specifically, with respect to an information storage medium that passes a high-temperature high-pressure high-humidity test (e.g., a pressure cooker test) under specific conditions, by adopting the above-described configuration, a roller that can perform inventory management, quality management, and the like (that can satisfactorily maintain the communication state of the information storage medium) can be realized. In addition, if the cover member is used in addition to the cured product of the thermosetting resin, the communication state of the information storage medium can be maintained more satisfactorily.
In addition, even in the case of an information storage medium that does not pass the high-temperature high-pressure high-humidity test under specific conditions, by using a cover having a thickness equal to or greater than a predetermined thickness in addition to the cured thermosetting resin, a roller (capable of maintaining the communication state of the information storage medium) that can perform inventory management, quality management, and the like can be realized.
This effect is particularly remarkable in elastic rolls (rubber rolls, urethane rolls, sponge rolls, etc.) that require a vulcanization step and a curing step.
According to the roller of the present invention, the information storage medium can be effectively protected by forming the cover from a specific thermosetting resin (heat-resistant material).
According to the roller of the present invention, interference (attenuation of radio waves) between radio waves from an information storage medium and a core material can be effectively suppressed. In addition, the information storage medium and the wireless device can be secured in a communication state of the information storage medium and the information storage medium can be protected. In addition, this effect is particularly remarkable when the core material is made of metal.
According to the roller of the present invention, the information storage medium can be more effectively protected by further using the storage container for storing the information storage medium. Further, the information storage medium can be more effectively prevented from being stored in the storage portion at a position closer to one side, and as a result, interference (attenuation of electric waves) between electric waves from the information storage medium and the core material (metal) can be more effectively suppressed.
According to the roller of the present invention, the deflection (directivity) of the radio wave can be suppressed by forming the information storage medium in a specific shape. In addition, the interference with the electric wave of the core material, which is easily generated when the rectangular information storage medium is used, can be more effectively suppressed.
According to the roller of the present invention, by using the passive RFID as the information storage medium, erroneous recognition between a plurality of rollers, which occurs when using an active (high-output) RFID, an IC tag having a wide communication range, or the like, can be effectively prevented. In addition, the present invention can be used without any problem in places such as iron works where it is required to prevent mutual interference with radio waves of other electronic devices. Further, since the battery does not need to be replaced, the roller can be used until the life of the roller is reached by only once mounting the roller for a long period of time.
According to the roller of the present invention, by providing the groove portion or the concave portion on the inner side surface of the housing portion and filling the inside of the groove portion or the concave portion with the cured product of the thermosetting resin, even when the cover (cured product of the thermosetting resin) is deteriorated, the cover can be prevented from coming off the housing portion more effectively by hooking the cured product of the thermosetting resin filled in the groove portion or the concave portion. As a result, the communication state of the information storage medium can be maintained more favorably.
According to the roller of the present invention, by adhering the information storage medium to the storage portion with the thermosetting resin, even when the information storage medium is repeatedly exposed to vibrations generated when the roller is used (rotated), the information storage medium can be prevented from being disturbed in the storage portion by the vibrations. As a result, the information storage medium can be more effectively prevented from malfunctioning due to vibration.

Detailed Description
Embodiments of the present invention will be described based on the drawings. The embodiments described below are merely examples of embodying the present invention, and do not limit the technical scope of the present invention.
(Basic structure)
First, the structure of the roller 1 of the present invention will be described with reference to fig. 1 to 3.
The roller 1 of the present invention has a core material 2, an information storage medium 3, and a cover 4 as main components.
In fig. 2 and 3, a storage container 5 for storing the information storage medium 3 is used in addition to the main components described above. Although this storage container 5 is not an indispensable constituent element in the present application, it is preferable to protect the information storage medium 3 and prevent interference of electric waves more effectively as described later.
The type of the roll 1 to be subjected to the present invention (the type of the coating layer 6 coated on the core material 2) is not particularly limited, and rolls to which various coating layers 6 are applied, such as a metal roll, a sponge roll, and a rubber roll, may be used. The present invention can be used not only for the roll in which the coating layer 6 is formed on the core material 2 as described above, but also for a roll in which a product is wound directly on the core material 2 without providing a coating layer, such as a paper roll or a film roll.
Among them, an elastic roll (rubber roll, urethane roll, sponge roll, etc.) having an elastic body produced by vulcanization or curing as the coating layer 6 is a roll capable of more effectively exhibiting the technical effects of the present invention.
Next, each constituent element will be described with reference to fig. 1 to 6.
(Core material)
The core material 2 used in the present invention has a columnar shape and includes a storage portion 7 for storing the information storage medium 3.
As described above, the core material 2 may be provided with various coating layers 6, or may be provided with no coating layer and a product may be directly wound around the core material 2. Here, when the roller 1 is provided with the coating layer 6, the core material 2 of the present application includes not only the shaft portion 2a but also the body portion 2b located between the shaft portion 2a and the coating layer 6, as shown in fig. 1 and 2.
The material of the core material 2 is not particularly limited, and various materials can be used.
The form of the housing 7 is not particularly limited, and various forms may be selected according to the environment in which the roller 1 is used.
Specifically, examples of the form shown in fig. 1 to 5 include a form in which the hole 7a provided in the core material 2 is used as the receiving portion 7, and a form in which the cylindrical portion 7b joined to the core material 2 is used as the receiving portion 7, as shown in fig. 6.
In the case of using the hole 7a as the housing 7, it is preferable to use a shape in which the opening 8 of the housing is circular, the bottom 9 of the housing is hemispherical (fig. 2 and 3), or a shape in which the opening is circular and the bottom is rounded (not shown), because the housing 7 can be easily manufactured by only punching (drilling).
In the case of using the tubular portion 7b as the housing portion 7, it is preferable to use a method of directly bonding a pipe cut to an appropriate length to an appropriate position of the core material 2 and a method of bonding a member cut to an appropriate length to a flat plate (fig. 6 (a)) after manufacturing the member and then bonding the member to an appropriate position of the core material 2 (fig. 6 (b)), because the housing portion 7 can be easily manufactured.
The housing portion 7 may be formed by providing a groove portion 10 or a recess portion on the inner surface of the housing portion 7 (the hole portion 7a or the cylindrical portion 7 b). Specifically, as shown in fig. 7 and 8, a groove 10 formed by cutting the entire inner surface of the hole 7a (fig. 7), a groove 10 formed by cutting the entire inner surface of the cylindrical portion 7b (fig. 8), and the like are provided. In fig. 7 and 8, the groove 10 is provided on the entire inner surface of the housing portion 7 (the hole 7a or the cylindrical portion 7 b), but the present invention is not limited to this, and a recess (not shown) may be provided by machining a part of the inner surface of the housing portion 7 (the hole 7a or the cylindrical portion 7 b).
In this case, when the cover 4 to be described later is formed, the thermosetting resin used is cured in a state of entering the groove 10 or the recess (the groove 10 or the recess is filled with the cured thermosetting resin). Therefore, even when the cover 4 (cured product of thermosetting resin) is deteriorated by repeated exposure of the roller to high temperature, high pressure, and high humidity, the cover 4 can be more effectively prevented from falling off from the storage portion by the cured product of thermosetting resin filled in the groove 10 or the recess.
The installation position of the storage portion 7 in the core material 2 is not particularly limited, and may be set at any position such as the center, end, peripheral surface, end surface, or the like of the core material 2 (the shaft portion 2a or the body portion 2b in the case where the roll 1 is provided with the coating layer 6).
Further, from the point that the roll information input to the information storage medium 3 can be easily read, and the information storage medium 3 can be easily attached and detached, exchanged, and the like, as shown in fig. 1 and 2, it is preferable that the roll is provided on the end face 11 of the core material (the end face 11a of the shaft portion 2a or the end face 11b of the body portion 2b in the case where the roll 1 is provided with the coating layer 6). In the case where the installation position of the storage portion 7 is the end face 11 of the core material, the size (diameter) of the opening 8 of the storage portion is preferably 25% or less of the diameter (Φ) of the end face 11 (in particular, the end face 11a of the shaft portion 2 a) of the core material in order to maintain balance between the strength of the roller shaft and the rotation of the roller.
(Information storage Medium)
The information storage medium 3 used in the present invention stores roll information. Specifically, various storage media such as an IC tag, an RF tag, and an RFID tag can be used. Further, if a passive RFID tag is used as the information storage medium 3, erroneous recognition with other rollers can be prevented because of a narrow communication range, and since the battery does not need to be replaced, it is preferable to realize a long-term service life. Further, since the passive RFID tag is difficult to cause interference of radio waves, it can be used without being affected by interference of radio waves with other electronic devices even in factories where various radio waves are staggered.
In the present invention, the cover 4 corresponds to stress from the outside, but it is preferable to use an information storage medium having heat resistance, pressure resistance, moisture resistance, chemical resistance, and the like for the information storage medium 3.
Specifically, the communication function can be maintained as a criterion for determination of the information storage medium 3 usable in the present application even after the high-temperature high-pressure high-humidity test (for example, a pressure cooker test) under the conditions of 155 ℃, 100% rh, 0.5MPa to 0.6MPa, and 3 hours is performed. That is, since the present application uses the cover member formed of the cured product of the thermosetting resin as an indispensable constituent element, the information storage medium 3 usable for the roller (in particular, the elastic roller) of the present application can be easily found from commercially available information storage media only by confirming whether or not the above-described high-temperature high-pressure high-humidity test is passed. This is an extremely useful insight in that: in many cases, the conditions of the actual vulcanization step and curing step performed in the elastic roller are more severe than the above conditions, but the above conditions can be used as a criterion.
The storage form of the information storage medium 3 in the storage portion 7 (core material 2) is not particularly limited, and can be determined according to the type of the information storage medium 3 and the roller used.
However, when the core material 2 is made of metal, it is necessary to prevent interference of electric waves generated between the information storage medium 3 and the housing portion 7 (core material 2). Specifically, it is necessary to provide a certain distance between the side surface and the upper surface of the information storage medium 3 and the housing portion 7 (core material 2).
More specifically, it is preferable that the information storage medium 3 is housed in the housing portion such that a distance (gap: G) between the side surface 12 of the information storage medium and the inner surface 13 of the housing portion is at least 1mm or more, and the upper surface 14 of the information storage medium is located at a depth (D) within 4mm from the opening surface 15 of the housing portion. The upper limit of the distance (gap: G) is not particularly limited, but if the distance (gap: G) becomes too large, the storage portion 7 becomes large, the processing of the storage portion 7 becomes difficult, or the cover 4 becomes large, so that it is preferably set to 2mm or less (1 mm to 2mm range). The lower limit value of the depth (D) is not particularly limited, but if the depth (D) is too shallow, the effect of the cover 4 is reduced, and thus, it is preferably set to 0.5mm or more (0.5 mm to 4mm range).
When the information storage medium 3 is stored in the storage portion 7 (core material 2), as shown in fig. 9, the information storage medium 3 may be bonded (fixed) to the storage portion 7 by using an adhesive or the like. Specifically, there are a form in which the information storage medium 3 is bonded to only the bottom of the hole 7a provided in the core material 2 (fig. 9 (a)), a form in which the information storage medium 3 is bonded to the bottom of the cylindrical portion 7b (fig. 9 (b)), a form in which the information storage medium 3 is bonded to the recess 20 described later (fig. 9 (c)) when the storage container 5 is used, and the like.
In such a configuration, even when the information storage medium 3 is repeatedly exposed to vibrations generated when the roller is used, the information storage medium 3 can be prevented from being disturbed in the housing portion 7 by the vibrations. As a result, the information storage medium 3 can be more effectively prevented from malfunctioning due to vibration, which is preferable.
The adhesive to be used is not particularly limited as long as it is a thermosetting resin, and if a thermosetting resin having the same material as the thermosetting resin described later is used, it is preferable because the adhesive strength can be more effectively prevented from being lowered even when the adhesive is repeatedly exposed to an environment of high temperature, high pressure and high humidity.
As the roll information stored in the information storage medium 3, the following roll information is exemplified.
Manufacturing number
Manufacturing year, month and day
Last maintenance (last re-coating) year, month and day
Delivery site
Use place (production line)
Type of elastomer
Initial film thickness of coating layer
Full length of roller
Outer diameter of roller
Length of surface of roller
The shape of the information storage medium 3 is not particularly limited, and various shapes may be selected. Among them, from the viewpoint of ease in manufacturing the housing portion 7 and the lid 16 described later, it is preferable that the housing portion be circular (disk-shaped) in plan view, as shown in fig. 2 to 6. Further, if the information storage medium 3 is formed in a circular shape (disk shape) in a plan view, deflection (directivity) of radio waves can be suppressed, which is preferable.
(Cover member)
The cover 4 used in the present invention is formed of a cured product of a thermosetting resin. Specifically, as shown in fig. 2 and 3, the cover 4 is provided on the upper portion of the information storage medium 3 so as to block the opening 8 of the storage portion, and is used to protect the information storage medium 3 from various stresses (particularly, under high-temperature, high-pressure, high-humidity environments). The sealing material (fixing material) also functions as a sealing material (fixing material) for sealing (fixing) the information storage medium 3 stored in the storage portion 7. Here, the storage container 5 described later also has a function of protecting the information storage medium 3 from stress, but in the present invention, basically the cover 4 functions to protect the information storage medium 3 from stress.
Therefore, in the present invention, the protective ability of the information storage medium 3 disappears without the cover 4.
This protection function is particularly remarkable when the roller 1 is an elastic roller (rubber roller, urethane roller, sponge roller, or the like) in which an elastomer produced by vulcanization or curing is used as the coating layer 6. That is, in the case where the roller 1 is an elastic roller, the re-coating is performed a plurality of times, but in this case, the present application can effectively prevent the occurrence of problems such as peeling, falling-off, communication failure, and the like of the information storage medium 3 by having the cover 4.
The material of the cover 4 is not particularly limited as long as it is a thermosetting resin, and the thermosetting resin having various physical properties can be selected according to the environment in which the roller 1 is used.
Further, in the case where the roll 1 is an elastic roll (rubber roll, urethane roll, sponge roll, or the like) in which an elastomer produced by vulcanization or curing is used as the coating layer 6, a thermosetting resin having physical properties of 130 ℃ or more, 180 ℃ or more, and 250 ℃ or more as measured in accordance with astm d648 or ISO75 is preferably used.
Examples of the thermosetting resin having such physical properties include epoxy resins, phenolic resins, silicone resins, polyester resins, and melamine resins. Among them, epoxy resins and phenolic resins are preferably used.
The shape of the cover 4 is not particularly limited, and various shapes can be selected according to the environment in which the roller 1 is used. Further, if the information storage medium 3 is sealed with an adhesive or a putty material, the opening 8 of the storage portion can be easily closed without any gap, which is preferable.
In addition, since the storage and management of the roller 1 are generally performed in a state where the roller 1 is set down (a state shown in fig. 1), when a material cured by curing such as an adhesive or a putty material is used for the cover 4, it is necessary to use a material which remains in a state where the material does not flow down to the opening 8 of the housing portion even in an initial state (a state immediately after the adhesive or the putty material is applied), that is, a material which has a certain degree of viscosity even in the initial state. Therefore, when a material cured by hardening such as an adhesive or a putty material is used for the cover 4, a material having a viscosity of 100pa·s or more at room temperature (25 ℃) in the initial state is preferably used, and among these, a material of 1000pa·s or more is preferably used, and further, among these, a material of 10000pa·s or more is preferably used.
In addition, when the groove 10 or the recess is provided on the inner side surface of the housing 7, the cover 4 may be formed by filling a cured product of the thermosetting resin in the groove 10 or the recess, as shown in fig. 7 to 9, in addition to the form of blocking the opening 8 of the housing. In this configuration, even when the cover 4 (cured product of thermosetting resin) is degraded by repeated exposure of the roller to high temperature, high pressure, and high humidity, the cured product of thermosetting resin filled in the groove 10 or the recess is caught, and hence the cover 4 can be prevented from falling off from the storage portion more effectively, which is preferable.
The thickness (T) of the cover 4 is not particularly limited, but from the viewpoint of protecting the information storage medium 3 from stress and preventing interference of electric waves generated between the information storage medium 3 and the housing portion 7, the thickness (T) of the cover 4 is preferably a thickness within 4 mm. The thickness (T) corresponds to the depth (D) described in [0045 ].
(Cover member: cover member)
In addition to the above-described modes (adhesive, putty material, etc.), as shown in fig. 2 to 6, a cover 16 made of plastic or glass (e.g., quartz glass, lead glass, borosilicate glass) may be used in combination with the cover 4. If the cover 16 is used in combination, the information storage medium 3 can be more effectively protected from stress, and the thickness of the cover itself can be made thin, which is preferable. That is, the communication state of the information storage medium 3 can be maintained more well while the information storage medium 3 is more effectively protected from stress.
In the case where a plastic cover is used for the cover 16, as described in [0050], a cover formed of a thermosetting resin having physical properties of 130 ℃ or higher, 180 ℃ or higher, and 250 ℃ or higher in terms of flexural temperature under load measured according to astm d648 or ISO75 is preferably used. That is, if a material made of a thermosetting resin of the same material as that of the cover member 4 (cured product of the thermosetting resin) is used as the cover member 16, a continuous protective layer of the same material as that of the cured product of the thermosetting resin provided so as to block the opening 8 of the storage portion is formed, and therefore the protective capability of the information storage medium 3 can be further improved.
Examples of the thermosetting resin having such physical properties include epoxy resins, phenolic resins, silicone resins, polyester resins, and melamine resins. Among them, epoxy resins and phenolic resins are preferably used.
The shape of the cover 16 is not particularly limited, and is preferably a disk shape matching a circular shape, which is a preferable shape of the opening 8 of the storage portion. As shown in fig. 4 and 6, the storage portion 7 is preferably large enough to be closed.
In the case where the storage container 5 is used, the lid 16 may be in the form shown in fig. 5 (a) and 5 (b). Specifically, the upper surface 17 of the lid may be coplanar with the upper end of the container 5 when the lid 16 is fitted to the container 5 and covered.
In addition, when the cover 16 is formed in this shape, the cover 16 does not completely block the storage portion 7, so that the function as a whole of the cover is reduced as compared with the configuration of fig. 4 and 6, but there is an advantage that the storage performance when the information storage medium 3 is stored in the storage container 5 can be further improved.
The thickness (T) of the cover 16 is not particularly limited, but since it forms a part of the cover 4, as described in [0053], the thickness (T) of the cover 16 is preferably adjusted so that the thickness (T) of the cover including the cover 16 is within 4 mm.
In the case of using the information storage medium according to [0044] which passes the high-temperature high-pressure high-humidity test as the information storage medium 3, the thickness (t) of the cover 16 is preferably 0.5mm to 2mm. On the other hand, when an information storage medium that does not pass the high temperature, high pressure and high humidity test as described in [0044] is used as the information storage medium 3, the thickness (t) of the cover 16 needs to be 1mm or more (preferably 1mm to 2 mm) from the viewpoint of protecting the information storage medium from stress.
The above is summarized as follows.
(1) Case of using information storage medium passing high temperature high pressure high humidity test
Thickness (T) of the cover as a whole: thickness (t) of the cover within 4 mm: 0.5 mm-2 mm.
(2) Use of information storage Medium that fails the high temperature high pressure high humidity test
Thickness (T) of the cover as a whole: thickness (t) of the cover within 4 mm: 1 mm-2 mm.
(Storage Container)
In the present invention, the storage container 5 for storing the information storage medium 3 may be used. The use of the storage container 5 is preferable because the information storage medium 3 can be more effectively protected from various stresses (particularly, under high-temperature, high-pressure, and high-humidity environments). In addition, in the case where the core material 2 is made of metal, the influence of the core material 2 (metal) can be more effectively eliminated, and radio waves from the information storage medium 3 can be more appropriately transmitted, which is preferable.
The material of the storage container 5 is not particularly limited, and various materials may be selected according to the environment in which the roller 1 is used. Further, in the case where the roller 1 is an elastic roller (rubber roller, urethane roller, sponge roller, or the like) in which an elastomer produced by vulcanization or curing is used as the coating layer 6, it is preferable to use a thermosetting resin having a load deflection temperature of 130 ℃ or more, 180 ℃ or more, and 250 ℃ or more measured according to astm d648 or ISO75, as in the case of the cover 4.
Examples of the material having such physical properties include epoxy resin, phenolic resin, silicone resin, polyester resin, melamine resin, and the like. Among them, epoxy resins and phenolic resins are preferably used.
The shape of the storage container 5 is not particularly limited, and various shapes can be selected according to the shape of the storage portion 7 and the environment in which the roller 1 is used. As shown in fig. 2 to 6, the container is preferably formed in a circular shape in a plan view, the opening 18 of the container is preferably formed in a circular shape, and the bottom 19 of the container is preferably formed in a hemispherical shape. With this shape, even when various stresses (particularly high-pressure stresses) are applied to the storage container 5, the stress concentration in the storage container 5 can be reduced by the effect of the circular or hemispherical shape. Therefore, it is possible to prevent a localized portion of stress from being generated inside the storage container 5, and to effectively protect the stored information storage medium 3 from the stress.
In addition, the shape of the storage container 5 is preferably the shape described above, since the storage container can be easily stored in the storage portion 7 formed by punching without any gap.
Further, as shown in fig. 3 to 6, a recess 20 for accommodating the information storage medium 3 is preferably formed in the storage container 5. According to this aspect, the information storage medium 3 can be easily placed in the center of the storage unit 7 without being displaced in the radial direction of the storage unit 7 by simply storing the information storage medium 3 in the recess 20. That is, the information storage medium 3 can be easily placed in the center of the housing 7, and the distance (gap: G) between the side surface 12 of the information storage medium and the inner surface 13 of the housing can be easily and uniformly maintained in the radial direction.
Therefore, if the recess 20 is provided in the storage container 5, a certain distance can be naturally secured between the information storage medium 3 and the core material 2, and as a result, the occurrence of interference of the electric wave can be more effectively prevented. In addition, this effect is particularly remarkable when the core material 2 is made of metal.
The shape of the recess 20 is not particularly limited, and may be determined according to the shape of the information storage medium 3 to be stored. Further, as shown in fig. 4 to 6, if the hollow is formed in a cylindrical shape, the stress concentration can be reduced, and the interference of the electric wave can be effectively prevented.
The size of the recess can be appropriately adjusted according to the size of the information storage medium to be stored. In addition, spacers may be used as needed.
The thickness (g) of the storage container 5 is not particularly limited, but from the viewpoint of protecting the information storage medium 3 and preventing radio interference, the storage container 5 preferably has a thickness of 1mm or more. The measurement position of the thickness (g) in the storage container 5 may be based on the thinnest portion of the storage container 5, but from the viewpoint of preventing interference of the electric wave, it is preferable to use the thickness of the thinnest portion of the storage container 5 when viewed in the radial direction as a reference. That is, it is preferable that the thickness (g 1) of the storage container 5 is based on the radial direction of the side surface 12 of the information storage medium. The thickness (G1) corresponds to the distance (gap: G) described in [0045 ].
Next, the operation and operation of the roller 1 configured as described above will be described with reference to fig. 1 to 4.
First, the information storage medium 3 is stored in the recess 20 of the storage container 5.
Next, the storage container 5 is stored in the storage portion 7 provided in the core material 2 of the roller 1.
Then, the lid 16 is attached to the upper portion of the container 5 to close the opening 18 of the container, and the cover 4 (adhesive or putty material in fig. 2 to 4) is coated on the upper portion thereof, thereby closing the container 7.
Finally, by curing the cover 4, the roller 1 of the invention is produced.
Then, as shown in fig. 1, the wireless device 21 is covered on the end of the roller 1, and the roller information stored in the information storage medium 3 is read. Further, new roll information is transmitted from the wireless device 21 and stored in the information storage medium 3, as necessary. Therefore, the roll information can be easily grasped at all times, and quality control, inventory control, and the like of the roll 1 can be efficiently performed.
In addition, when the roll 1 requires recoating of an elastic body (coating layer 6) such as an elastic roll, even in a contaminated state sent to the manufacturer, roll information can be easily grasped, and errors can be effectively prevented from occurring during the recoating operation.
Examples
Next, the roller of the present invention will be described in detail based on examples and comparative examples. The present invention is not limited to the following examples.
( Test example 1: test for positional relation between information storage Medium and storage section (core Material) )
First, a test was performed on the position of the information storage medium in the housing portion (core material), and this test enabled communication between the information storage medium and the core material without causing interference of electric waves. Specifically, as shown in fig. 10, a cylindrical hollow (accommodation portion (hole portion)) was provided in an iron material imitating a core material, and an information storage medium 3 was accommodated in the accommodation portion (hole portion), and samples of each test example were produced by variously changing (1) a distance (gap: G) between a side surface 12 of the information storage medium and an inner surface 13 of the accommodation portion when viewed in a radial direction and (2) a depth (D) from an opening surface 15 of the accommodation portion to an upper surface 14 of the information storage medium.
Then, it was tested whether or not the information storage medium could communicate without any problem in the storage section (core material). Further, as an evaluation criterion, by ∈: stable communication state of sufficient radio wave intensity is ensured, Δ: unstable communication state with weak radio wave intensity, ×: the 3 criteria of poor communication were evaluated.
The results are shown in Table 1.
TABLE 1
As a result, it was found that if the information storage medium is stored in the storage portion (core material) such that the distance (gap: G) is 1mm or more and the depth (D) is within a range of 4mm, the information storage medium can maintain a stable communication state.
( Test example 2: test for determination criterion of information storage Medium )
Next, a test was performed on a criterion for determining an information storage medium that can be used even when exposed to an environment of high temperature, high pressure, and high humidity. Specifically, 2 kinds of commercially available information storage media (passive RFID) were tested for (1) a test under steam-resistant vulcanization conditions (155 ℃, 100% rh, 0.5 to 0.6MPa, 3 hours) (high-temperature high-pressure high-humidity test) and (2) a test under hot-water-resistant vulcanization conditions (160 ℃, hot-water immersion, 1.6MPa, 3 hours), and whether communication failure occurred after the test was tested.
Information storage medium 1 (model number JOPPD, manufactured by king company)
Information storage medium 2 (manufactured by Beijing ceramic Co., ltd., model: 0502)
Information storage medium 3 (manufactured by Beijing ceramic Co., ltd., model: 0603)
Information storage medium 4 (manufactured by letterpress printing Co., ltd., model number SMARTRAC)
Information storage medium 5 (model LXTBKZMCMG-010 manufactured by village field manufacturing company)
Information storage medium 6 (model: dot-On XS, manufactured by the company of the Loose, wipe, inc.)
Further, as an evaluation criterion, by ∈: stable communication state of sufficient radio wave intensity is ensured, Δ: unstable communication state with weak radio wave intensity, ×: the 3 criteria of poor communication were evaluated.
The results are shown in Table 2.
TABLE 2
As a result, it was found that there was an information storage medium which was poor in communication in the test under the temperature-resistant water vulcanization condition, but was capable of communication without problems in the test under the vapor vulcanization condition (high-temperature high-pressure high-humidity test).
It is apparent from the results of examples 1 to 21 and 28 (using the information storage medium 6) described later that the information storage medium passed the test under the steam-resistant vulcanization condition (high-temperature high-pressure high-humidity test), even if the information storage medium was an information storage medium having poor communication in the test under the hot-water-resistant vulcanization condition, the information storage medium could be an information storage medium constituting the present application. That is, it is known that if an information storage medium that is acceptable in a test under a steam-resistant vulcanization condition (high-temperature high-humidity test) is used, the information storage medium that can be used in the present application (that can pass 10 endurance tests (re-coating operation)) can be obtained by the synergistic effect of the durability of the information storage medium itself and the cover.
From the above, it is clear that the test (high temperature high pressure high humidity test) under the steam curing condition (155 ℃, 100% rh, 0.5 to 0.6mpa, 3 hours) of (1) is not the test under the hot water curing condition of (2) but is appropriate as a criterion for the information storage medium usable in the present application.
In addition, if this determination criterion is used, options (for example, cost-wise options) that can be used for the information storage medium of the present application can be extended. Therefore, from this point of view, this criterion is also useful.
Next, samples of examples and comparative examples using the core material (storage portion), the information storage medium, and the cover were prepared and evaluated according to the above-described test examples 1 and 2. Since the actual roll was a very large roll (core material: diameter 2m×length 10m, etc.), samples simulating the constitution of the roll were prepared and evaluated for examples and comparative examples.
Example 1
First, a phenolic resin molded body (load deflection temperature: 250 ℃ (stress: 1.8 MPa)) was processed to produce a container and a lid having the following dimensions.
Outer dimensions of the container: diameter 10mm x height 6mm, and bottom is hemispherical with radius (R) 5mm
Thickness (g 1): 2mm of
Concave part: cylindrical cavity with diameter of 6m x depth of 4mm
Cover external dimensions: disc-shaped with diameter of 10mm x thickness (t) of 1mm
Then, the iron material was perforated to provide hemispherical holes (receiving portions) having a diameter of 10mm, a height of 10mm, and a bottom portion having a radius (R) of 5 mm.
Next, as the information storage medium, an information storage medium 6 (model Dot-On XS, manufactured by the back-up company, model number 6mm diameter by 2.5mm height) which passed the high temperature high pressure high humidity test was used. Then, a spacer having a thickness of 1.5mm is placed in the bottom of the recess of the storage container, and the information storage medium 6 is placed on the spacer, whereby the information storage medium is stored in the recess of the storage container. Then, the container is accommodated in a hole (accommodation portion) of the iron material, and the upper portion of the container is closed with a lid.
The hole (housing), the housing container (including the recess), and the lid are formed so that the respective surfaces thereof are smooth surfaces free from large irregularities, and thus the components can be easily housed (inserted).
Next, an epoxy adhesive (viscosity: 10000pa·s (25 ℃) and load deflection temperature after curing: 180 ℃ (stress: 1.8 MPa)) was applied to the upper portion of the lid member so as to close the opening of the hole portion (receiving portion) and to have a thickness of 3 mm.
Finally, by curing the epoxy adhesive, a sample of example 1 was produced in which a cover (cured material of epoxy adhesive+cover) having a thickness (T) of 4mm was formed on the upper portion of the information storage medium as shown in fig. 11.
(Example 2-example 13)
Samples of examples 2 to 13 were produced in the same manner as in example 1 except that the thickness of the cover (cured epoxy adhesive+cover) was changed to the thickness shown in table 3.
(Example 14-example 21)
Samples of examples 14 to 21 were produced in the same manner as in example 1, except that the thickness of the epoxy adhesive was changed to the thickness shown in table 3 without using a cover.
Example 22
Samples of example 22 were produced in the same manner as in example 1 except that the information storage medium was changed to the information storage medium 1 (disc shape having a diameter of 6 mm. Times. Height of 4mm, manufactured by Newland Japan Co., ltd.; model number JOPPD) and a spacer was not used.
(Example 23-example 27)
Samples of examples 23 to 27 were produced in the same manner as in example 22 except that the thickness of the cover (cured epoxy adhesive+cover) was changed to the thickness shown in table 4.
Example 28
First, an iron pipe having an inner diameter of 10mm and a thickness of 2.5mm was cut into a length of 10mm, and the iron pipe was welded to an iron plate having a thickness of 60mm×25mm×2mm, whereby a cylindrical portion (housing portion) was produced.
Next, the information storage medium 6 is used as an information storage medium, and the information storage medium is stored in the recess of the storage container together with the spacer, similarly to the case described in [0077 ]. Then, the container was housed in a cylindrical portion (housing portion), and the upper portion of the container was closed with a lid (thickness: 1 mm) described in [0075 ].
Next, an epoxy adhesive (viscosity: 10000pa·s (25 ℃) and load deflection temperature after curing: 180 ℃ (stress: 1.8 MPa)) was applied to the upper portion of the lid member so as to close the opening of the cylindrical portion (receiving portion) and to have a thickness of 3 mm.
Finally, by curing the epoxy adhesive, a sample of example 28 (form of fig. 6 (b)) was produced in which a cover (cured epoxy adhesive+cover) having a thickness (T) of 4mm was formed on the upper portion of the information storage medium.
Comparative example 1
A sample of comparative example 1 was produced in the same manner as in example 1, except that an epoxy adhesive was not used.
Comparative example 2
A sample of comparative example 2 was produced in the same manner as in example 7, except that an epoxy adhesive was not used.
(Comparative examples 3 to 9)
Samples of comparative examples 3 to 9 were produced in the same manner as in example 22 except that the thickness of the cover (cured epoxy adhesive+cover) was changed to the thickness shown in table 4.
(Comparative examples 10 to 17)
Samples of comparative examples 10 to 17 were produced in the same manner as in example 22, except that the thickness of the epoxy adhesive was changed to the thickness shown in table 4 without using a cover.
Comparative example 18
A sample of comparative example 18 was produced in the same manner as in example 22, except that an epoxy adhesive was not used.
Comparative example 19
A sample of comparative example 19 was produced in the same manner as in example 22, except that the thickness of the cover was changed to 0.5mm without using an epoxy adhesive.
(Evaluation method and evaluation result)
Next, the samples of examples 1 to 28 and comparative examples 1 to 19 were evaluated. Specifically, durability tests under multiple vulcanization conditions were performed, and it was evaluated whether communication failure did not occur in the information storage medium after each test. Regarding the vulcanization conditions, durability tests were conducted under 160℃and hot water immersion, 1.6MPa, 5 hours, which are one of the conditions (hot water vulcanization conditions) of the actual vulcanization process. Further, as an evaluation criterion, by ∈: stable communication state of sufficient radio wave intensity is ensured, ×: an unstable communication state or communication failure, in which the radio wave intensity was weak, was evaluated.
The results are shown in tables 3 and 4.
(Table 3)
(Table 4)
As is clear from tables 3 and 4, the information storage medium maintained a good communication state even after a plurality of durability tests for the samples of the examples having the constituent elements of the present application.
Samples of examples 1 to 21 and 28 using the information storage medium passing the high-temperature high-pressure high-humidity test maintained good communication state even after the durability test.
In particular, it is clear from the evaluation results of the samples of examples 14 to 20 that the cover material made of only the cured product of the thermosetting resin can pass 10 endurance tests when the information storage medium passed the high-temperature high-pressure high-humidity test. It is to be noted that, although the sample of example 21, in which the thickness of the cover was the thinnest (0.5 mm), failed 10 durability tests, the sample failed 5 durability tests, and therefore, it was found that the roller was sufficiently usable as long as the limitation was placed on the use period.
Further, as is clear from the evaluation results of the samples of examples 22 to 27, even in the case of the information storage medium which did not pass the high temperature high pressure high humidity test, the durability test was passed although the number of times of the durability was reduced by using the cover member having a thickness (t) of 1mm or more in combination with the cured thermosetting resin. That is, it is found that even in the case of an information storage medium that fails the high-temperature high-pressure high-humidity test, by adopting specific components, a roller that can be used sufficiently as long as the use period is restricted can be obtained in the same manner as the sample of example 21.
On the other hand, the sample of the comparative example having no constituent element failed the durability test at a time, and an unstable communication state and communication failure were generated.
In particular, as is clear from the evaluation results of the samples of comparative examples 1 and 2, even in the case of the information storage medium passing the high-temperature high-pressure high-humidity test, the durability test could not be qualified once without the cover (cured product of thermosetting resin).
Further, when the results of the evaluation of the samples of comparative examples 3 to 9 and the results of the evaluation of the samples of examples 22 to 27 were compared and observed, it was found that, when the thickness of the cover member was 0.5mm (the thickness of the cover member was less than 1 mm) for the information storage medium that failed the high temperature high pressure high humidity test, the durability test could not be qualified once even if the thickness of the cover member including the cover member was the same as the samples of examples 22 to 27.
Further, as is clear from the evaluation results of the samples of comparative examples 10 to 17 and the evaluation results of the samples of comparative examples 18 and 19, if any of the elements "cured product of thermosetting resin" and "cover having a thickness (t) of 1mm or more" is missing as the structure of the cover member, the durability test cannot be qualified once for the information storage medium that fails the high-temperature high-pressure high-humidity test. In particular, as is clear from the evaluation results of the samples of comparative example 10, in the case where the cover had a structure without a cover (in the case where the cover was made of only a cured product of an epoxy adhesive), the durability test could not be qualified once even if the thickness of the cover as a whole was 4 mm. It is also clear from the evaluation results of the samples of comparative examples 18 and 19 that the durability test could not be accepted once even when the cover member had a structure of only the cover member (when the cover member had a structure of a cured product of an epoxy-free adhesive).
As described above, when an information storage medium that does not pass the high-temperature high-pressure high-humidity test is used as the information storage medium, it is necessary to provide a cover member in addition to the cured product of the thermosetting resin, and the thickness thereof becomes an important factor.
Example 29
Next, a sample was prepared by providing a groove portion on the inner surface of the housing portion.
First, a hemispherical hole (receiving portion) having a diameter of 10mm, a height of 10mm, and a bottom portion having a radius (R) of 5mm is formed by punching an iron material.
Next, a groove portion having a depth of 1.0mm was formed by cutting Φ6 (manufactured by seta corporation) straight around the inner surface having a depth of 1.0mm from the opening surface of the hole portion (housing portion) using a high-speed steel cutter.
The subsequent steps were performed in the same manner as in example 1 to prepare a sample of example 29 (a form similar to that of fig. 7).
Example 30
Next, a sample is produced in which the information storage medium is bonded (fixed) in the storage section.
First, a hemispherical hole (receiving portion) having a diameter of 10mm, a height of 10mm, and a bottom portion having a radius (R) of 5mm is formed by punching an iron material.
Next, using the storage container and the lid described in [0075], an epoxy adhesive (viscosity: 10000pa·s (25 ℃) and a load deflection temperature after curing: 180 ℃ (stress: 1.8 MPa)) was applied to the information storage medium using the information storage medium 6 instead of the spacer so as to have a thickness of 1.5mm, and then the information storage medium was placed thereon, and cured, whereby the information storage medium was adhered (fixed) to the recess of the storage container.
The subsequent steps were performed in the same manner as in example 1 to prepare samples of example 30 (a form similar to that of fig. 9 (c)).
Next, samples of example 29 and example 30 were evaluated.
Specifically, the sample of example 29 was evaluated by the evaluation method and the evaluation standard described in [0091 ]. For the sample of example 30, vibration test was performed using a vibration tester (model: F-16000BDH/LA16AW, manufactured by the Kyoto Co., ltd.) under the conditions of frequency=10 to 55HZ, acceleration=19.6 m/s 2 (2G), and scanning cycle number=10, and whether communication failure did not occur in the information storage medium after the test was evaluated. The evaluation criterion was evaluated by the same criterion as the evaluation criterion described in [0091 ].
As a result, the sample of example 29 maintained a good communication state even after 10 durability tests. In addition, for the sample of example 30, a good communication state was maintained after the vibration test (o evaluation).
