JP5173630B2 - Roll information management member - Google Patents

Description

  The present invention relates to a roll information management member for managing information related to a roll used in a rolling mill.

  Conventionally, a roll used in a rolling mill is replaced with a new roll having a polished roll surface when the roll surface is worn by rolling a workpiece such as metal. Therefore, the roll shop attached to the rolling mill is equipped with a roll polishing device for polishing new rolls immediately after purchase, old used rolls, etc., and for applying dull processing to polished rolls. A dull processing device and a device for carrying and exchanging these rolls are also provided. Many of the various operations such as polishing and dull processing (hereinafter referred to as roll shop operations) in the roll shop are performed manually by the operator, and thus require labor and skill of the operator. Therefore, in recent years, various methods for automating the roll shop work have been proposed for the purpose of saving labor and improving the efficiency of the roll shop work.

  For example, the processing unit for rolling mill, the processing unit for roll shop and the processing unit for roll data management are connected to each other, and data is transmitted and received between the rolling mill, the roll transfer unit, and the roll grinder with chock. Thus, it is possible to automate the sorting of the normal roll and the accident roll, the collection and setting of roll data, and the control of the roll grinder with chock and the roll transfer means without requiring an operator. Thus, there is known an automatic operation method and apparatus for roll shop work that can perform all of a series of processes by automatic operation (see, for example, Patent Document 1).

  In addition, a series of roll scheduling functions such as rolling schedule, roll reassignment / grinding / conveyance / schedule, etc. are integrated into a computer system, making scheduling that was difficult even for the judgment of the operator fully automated. There is known an integrated roll shop operation method capable of performing (see, for example, Patent Document 2).

  Further, the total rolling time and grinding time are compared by the grinding load prediction management system, and when the grinding time is insufficient, the production instruction information is changed by the production management system. On the other hand, if the grinding time is not short, the rolling mill and roll transport based on the rolling order confirmation information that has the smallest grinding load margin coefficient αK obtained from the ratio of rolling time and grinding time for each steel strip. Control equipment and grinder. Thus, there is known a technique in which the rolling roll required for the rolling mill is ground and supplied without excess and deficiency to prevent rolling suspension due to grinding delay and eliminate excessive grinding of the rolling roll (for example, (See Patent Document 3).

  In the inventions described in Patent Documents 1 to 3, all the roll shop work is automated to save labor for the entire system, but information on individual rolls cannot be efficiently managed. In other words, these conventional technologies cannot efficiently and accurately manage the current position, current usage status, past usage history, current roll diameter, etc. of each roll as information about individual rolls in the roll shop. It has been difficult for a person to obtain various information about a desired roll.

  Therefore, in the conventional roll shop work, when a situation that requires a specific roll occurs, when an operator wants to find the roll by walking in the roll shop or to know the past usage history for a specific roll In some cases, the worker refers to a management book written manually, and the worker has a lot of trouble. Also, the operator has determined whether or not the roll used in the rolling mill has an optimal roll diameter based on experience, but such determination requires the skill of the operator.

  As described above, if the information about individual rolls cannot be managed efficiently and accurately, there is a problem that the labor saving and efficiency improvement of the roll shop work is hindered. In particular, in a rolling mill (for example, Sendzimir mill) using a small-diameter roll, the number of rolls to be used is larger than that of a rolling mill using a large-diameter roll, and the replacement frequency of the old and new rolls is increased. Then, the number of rolls in which roll shop work is performed also increases, and it has become more difficult to efficiently and accurately manage information about all these rolls.

  An object of the present invention is to provide a roll information management member capable of efficiently and accurately managing information relating to a roll used in a rolling mill.

  In the present invention, the following features are provided alone or in combination as appropriate.

A roll information management member according to the present invention for solving the above-mentioned problems is a roll information management member that holds an information storage medium capable of storing information about a roll used in a rolling mill in a non-conductive main body. And the said main-body part can accommodate the said information storage medium formed in the fitting part which is formed in the one end surface, and can be fitted or detached with respect to the edge part of the said roll, and the other end surface. A storage unit, and the storage unit is formed at a position where information on the roll can be written and / or read by wireless communication with respect to the information storage medium stored in the storage unit. It is characterized by that.

According to the said structure, a roll information management member hold | maintains the information storage medium which can memorize | store the information regarding the roll used for a rolling mill in the main-body part which has nonelectroconductivity. And the main-body part has the fitting part which can be freely attached or detached with respect to the edge part of the roll formed in the one end surface, and can attach a roll information management member to a roll with this fitting part. it can. Further, the main body portion has a storage portion that is formed on the other end surface and can store the information storage medium, and the information storage medium can be disposed in the storage portion. And this accommodating part is formed in the position which can write in and / or read the information regarding a roll by radio | wireless communication with respect to the information storage medium accommodated in the said accommodating part.

  Here, the “information storage medium” stores at least identification information unique to the information storage medium. This unique identification information corresponds to “information about the roll”, and functions as identification information for identifying each roll to which the roll information management member is attached. As “information about rolls”, the current position of each roll, the current use state, the past use history, the current roll diameter, and the like may be stored. The “information storage medium” is a non-contact type storage medium that can be written and / or read by wireless communication, and specifically, a non-contact type IC tag (so-called RFID) is exemplified.

  In addition, “non-conductive” means low electrical conductivity (or high electrical resistance), and at least an information storage medium arranged inside the main body is written from outside by wireless communication or / And the conductivity needs to be low enough to be readable. Therefore, the main body portion is made of an insulating material (rubber, plastic, etc.) that is difficult to conduct electricity because it is non-conductive. In other words, the main body portion has a function of separating the information storage medium from a metal body (here, a roll) that reflects radio waves by being made of a substance that allows radio waves to pass through.

  Here, if the roll (at least the edge of the roll) is made of a conductive metal such as iron, a radio signal related to the information storage medium is reflected, and writing or / and reading to the information storage medium is hindered. There is a fear. On the other hand, since the main body portion is “non-conductive”, it does not reflect a radio signal related to the information storage medium (or the reflectivity of the radio signal is low), and writing to and / or reading from the information storage medium. There is no risk of disturbing.

  And, the “position where the information on the roll can be written or / and read by wireless communication” formed in the main body is the position where the roll information management member is attached to the edge of the roll by the fitting portion. In addition, the position where writing or / and reading of information with respect to the information storage medium in the storage unit is not hindered by the roll. Specifically, the accommodating portion is formed in the main body portion so as to be separated from the fitting portion attached to the end edge portion of the roll to such an extent that the roll does not affect electrically. Thereby, even if a fitting part is attached with respect to the edge part of a roll, the writing or / and reading of the information with respect to the information storage medium in a storage part is attained.

  Thereby, the roll information management member can be attached to the edge portion of the roll in a state where an information storage medium capable of storing information on the roll is held. And even if the roll used for a rolling mill is comprised with the electroconductive metal, it can enable writing and / or reading of information to this information storage medium by radio | wireless communication. Therefore, each roll is uniquely identified by referring to the unique identification information stored in the information storage medium only by attaching the roll information management member to each of the plurality of rolls used in the rolling mill and the roll shop. Is possible.

  If the detailed information (current position, current usage status, past usage history, current roll diameter, etc.) of each roll is centrally managed in the management device, the roll information attached to each roll is managed. It is only necessary to refer to the information storage medium held by the member and appropriately register the detailed information of each roll based on the identification information unique to the information storage medium (that is, roll identification information). Thereby, when an operator wants to know detailed information about a specific roll, the detailed information can be obtained simply by making the management device search using the identification number of the roll as a key. Information on roles used in the shop can be managed efficiently and accurately.

  It should be noted that the detailed information of each roll is stored in the information storage medium held in the roll information management member attached to each roll instead of or in addition to the centralized management of the detailed information of each roll by the management device. May be written by wireless communication. According to this, when an operator wants to know detailed information about a specific roll, the detailed information on the roll is directly read by wireless communication from an information storage medium held in a roll information management member attached to the roll. So that work efficiency is improved.

  In the roll information management member according to the present invention for solving the above-mentioned problems, the main body portion is a cylinder that is substantially coaxial with the axis of the roll in a state where the fitting portion is fitted to an end edge portion of the roll. It is preferable that the outer diameter of the main body is larger than the maximum diameter of the roll.

  According to the said structure, a main-body part makes | forms the cylindrical body which makes a substantially coaxial with the axis line of the said roll in the state by which the fitting part was fitted by the edge part of the roll. That is, when the roll information management member is attached to the roll, the axis of the main body forming the cylindrical body and the axis of the roll having a substantially cylindrical shape substantially coincide. And although the outer diameter of the main body is larger than the maximum diameter portion of the roll, generally the maximum diameter portion of the roll is a body portion that comes into contact with a workpiece such as metal when used in a rolling mill. Therefore, it can be said that the outer diameter of the main body is larger than the outer diameter of the body of the roll.

  As a result, when the roll information management member is attached to the end edge of the roll, the main body protrudes most radially outward as seen from the axis of the main body and the roll. Therefore, when a plurality of rolls are arranged in parallel, even if the adjacent rolls move in a direction in which they are close to each other, the roll information management member attached to each roll is not Each abuts against the body of the adjacent roll or the roll information management member. Therefore, even if a plurality of rolls are arranged adjacent to each other, it is possible to prevent the roll body parts from coming into contact with each other and causing damage or damage to the roll surface.

  In the roll information management member according to the present invention for solving the above-mentioned problems, it is preferable that the main body is integrally formed of an elastic material and has flexibility. This is because the structure of the main body can be simplified by integrally forming the main body with an elastic material, and the manufacturing process and product cost of the roll information management member can be reduced. In addition, since the main body portion is flexible, it can be easily attached to and detached from the roll, and damage due to shot blasting in a dull processing machine can be prevented.

  In addition, rubber is exemplified as the “elastic material”, but the main body portion is deformed due to heat generation of the roll at the time of shot blasting, and the fitting portion is prevented from being detached from the edge portion of the roll. Therefore, it is desirable that the “elastic material” has a predetermined heat resistance.

  In the roll information management member according to the present invention for solving the above-mentioned problem, the end edge portion of the roll is a neck portion having a smaller diameter than a body portion used for rolling a workpiece in the rolling mill. When the fitting portion is fitted to the end edge portion of the roll, it is preferable to enclose substantially the entire neck portion.

  According to this, the edge part of a roll is a neck part (neck part) which makes a diameter smaller than the trunk | drum used for rolling of workpieces, such as a metal, with a rolling mill. In other words, the edge part of a roll is a site | part which is not used for the rolling of the workpiece in a rolling mill. This roll neck has different uses and functions depending on the type of rolling mill.For example, the roll neck functions as a part to be gripped by an operator when the roll is attached to or detached from the rolling mill. It functions as a part that is pivotally supported.

  When the fitting portion is fitted to the end edge portion of the roll, substantially the entire roll neck is enveloped by the fitting portion. In other words, in a state where the roll information management member is attached to the roll, since the substantially entire roll neck portion is protected from the outside by the fitting portion, for example, the projection material is applied to the roll neck portion even during shot blasting. Collision can be prevented, and damage and breakage of the roll neck can be prevented.

  In the roll information management member according to the present invention for solving the above-mentioned problem, the fitting portion includes a concave portion into which an end edge portion of the roll is fitted, and an outer periphery of the roll fitted into the concave portion. It is preferable to have at least a locking portion that protrudes toward the surface and locks the roll on the inner surface of the recessed portion.

  According to this, the fitting part has the recessed part by which the edge part of a roll is fitted. The recessed portion has substantially the same diameter and substantially the same shape as the end edge of the roll so as to be closely fitted to the end edge of the roll. Further, the recessed portion has a depth (distance from the opening to the inner bottom portion of the recessed portion) that allows insertion of substantially the entire edge of the roll, and specifically, the end of the roll. It has a depth that substantially matches the axial length of the edge.

  Moreover, the fitting part has the latching | locking part protruded and formed toward the outer peripheral surface of the roll fitted by the recessed part. Therefore, when viewed from the axis of the main body portion, the distance to the locking portion is slightly smaller than the distance to the inner surface of the recessed portion. In addition, this latching | locking part may be formed over the perimeter in the inner surface (an inner peripheral surface if a recessed part is cylindrical) of a recessed part, and may be formed partially. Moreover, although the cross-sectional shape and protruding shape of the locking portion can be arbitrarily formed, the protruding width of the locking portion is such that the operator can intentionally apply external pressure to insert and remove the roll with respect to the recessed portion. Is preferred.

  When the roll is fitted into the recessed portion, the roll is locked on the inner surface of the recessed portion by the pressing force applied from the locking portion to the roll surface side. Thereby, when a roll information management member is attached to a roll, even if vibration or rotational force is given to a roll by shot blasting etc., the malfunction that a roll information management member will remove from the said roll can be prevented, for example.

  The roll information management member according to the present invention for solving the above-described problems is provided with a sealing member that seals the information storage medium accommodated in the accommodating portion, and the sealing member is at least the accommodating It is preferable that the information storage medium accommodated in the unit has a light-transmitting property. According to this, since the information storage medium accommodated in the accommodating part can be sealed with the sealing member, it is possible to prevent a problem that the information storage medium is removed from the roll information management member. Moreover, since the sealing member has translucency, the information storage medium accommodated in the accommodating portion can be visually recognized even when the sealing member is sealed with the sealing member. Therefore, even if the sealing member is not removed each time, it can be confirmed whether or not the information storage medium is accommodated in the accommodating portion, and the burden on the operator can be reduced.

  The sealing member is made of a transparent material having translucency, and made of a conductive material that does not hinder writing or / and reading of information with respect to the information storage medium in the housing portion. For example, rubber, glass, plastic or the like. Moreover, the sealing member should just have the transparency which can confirm the presence or absence of the information storage medium in an accommodating part at least.

  ADVANTAGE OF THE INVENTION According to this invention, the information regarding the roll used with a rolling mill can be managed efficiently and correctly.

  Hereinafter, the roll information management member according to the present invention will be specifically described with reference to the drawings. In the present embodiment, a roll end cover 1 mainly made of rubber will be described as an example of a roll information management member.

  A roll end cover 1 according to the present embodiment (see FIG. 1 and the like to be described later) is a member that is attached to and detached from a roll used in a processing machine for rolling a workpiece such as metal, and more specifically, a Sendzimir mill. It is attached to and detached from a relatively small diameter roll used in the The roll end cover 1 is configured to be able to hold an information storage medium in which various types of information can be written and / or read by wireless communication, and the information storage medium is physically attached to the roll to which the roll end cover 1 is attached. It has a function of associating (so-called linking).

  First, with reference to FIG. 1 and FIG. 2, the outline | summary of the roll end cover 1 and the roll 100 which concern on this embodiment is demonstrated. FIG. 1 is a schematic perspective view for explaining the external appearance of the roll end cover 1 and the roll 100. FIG. 2 is a schematic perspective view for explaining the appearance of the roll end cover 1 and the roll 100 as seen from a direction different from that in FIG.

  As shown in FIGS. 1 and 2, the roll end cover 1 has a non-conductive main body 10 having a substantially cylindrical shape whose height (axial length) is slightly smaller than the diameter. One end surface of the main body 10 is formed with a fitting portion 20 that can be freely attached to and detached from the edge of the roll 100, and the other end surface of the main body 10 can accommodate a wireless IC tag to be described later. An accommodating portion 30 is formed. Moreover, since this main-body part 10 is integrally molded by the heat-resistant rubber | gum as a nonelectroconductive material, the roll end cover 1 has the flexibility which can deform | transform according to an external pressure as a whole.

  Here, “non-conductive” means low electrical conductivity (or high electrical resistance), and at least a wireless IC tag disposed in the main body 10 is written or externally written by wireless communication. / And the conductivity is low enough to be readable. Here, since the main body portion 10 is made of rubber, which is an insulating material that hardly conducts electricity as a non-conductive material, the main body portion 10 does not reflect a wireless signal related to the wireless IC tag (or the wireless signal). Since the reflectance is low, there is no possibility of hindering writing or / and reading with respect to the wireless IC tag.

In the present embodiment, the main body portion 10 is made of natural wear-resistant rubber that satisfies the above conditions, and the typical hardness (Duro-A) is an example of the performance required for this natural wear-resistant rubber under normal conditions. Mold) “37-47”, tensile strength “20 Mpa or more” and “204 kgf / cm ² or more”, elongation rate “500% or more”. Here, the natural wear-resistant rubber constituting the main body portion 10 has a standard hardness (Duro-A type) “43”, a tensile strength “22.7 Mpa” and “232 kgf / cm ² ”, and an elongation “620%”. Suppose that

  On the other hand, the roll 100 is an iron roll having a relatively small diameter (specifically, 65 mm to 85 mm) used in a rolling mill such as a Sendzimir mill. The roll 100 is formed at a cylindrical main body (body portion) 110 that rolls a workpiece when used in a rolling mill, and at both end edges of the roll 100 and has a slightly smaller diameter than the body portion 110. A neck portion (neck portion) 120 is integrally formed.

  In addition, in this embodiment, the neck part 120 functions as a site | part gripped when incorporating the roll 100 with respect to a rolling mill, for example. Further, the neck portion 120 is formed with a groove portion 121 having a smaller diameter than the neck portion 120 at a portion connected to the body portion 110 in the neck portion 120.

  And when attaching the roll end cover 1 with respect to the roll 100, the said roll end cover 1 is made to adjoin to the state which the fitting part 20 opposes the edge side of the roll 100. FIG. Then, external pressure is applied to the roll end cover 1 so that the neck 120 of the roll 100 is fitted into the fitting portion 20 of the roll end cover 1. Thereby, the roll end cover 1 is attached to the roll 100, and the wireless IC tag accommodated in the accommodation unit 30 is physically associated with the roll 100.

  On the other hand, when removing the roll end cover 1 from the roll 100, external pressure is applied to the roll end cover 1 in a direction in which the fitting portion 20 is separated from the neck portion 120 of the roll 100, and the neck portion 120 is fitted. Pull out from part 20. As a result, the roll end cover 1 is removed from the roll 100, and the physical association with the roll 100 is released for the wireless IC tag accommodated in the accommodating unit 30 (the data stored in the wireless IC tag is stored). Not disappear).

  Next, with reference to FIG. 3 and FIG. 4, the detail of the physical structure of the roll end cover 1 and the roll 100 which concerns on this embodiment is demonstrated. FIG. 3 is a side sectional view of the roll end cover 1. FIG. 4 is a side sectional view of the roll 100 with the roll end cover 1 attached thereto. Note that the axis O shown in FIG. 3 indicates the axis of the main body 10 having a substantially cylindrical shape.

  As shown in FIG. 3, the main body portion 10 of the roll end cover 1 has a cylindrical wall portion 12 perpendicular to the base end portion 11 along the outer peripheral edge of a thin plate-like base end portion 11 having a substantially circular shape. As a whole, it has a substantially U-shaped cross-sectional shape in a side view. In addition, the outer diameter L1 of the main-body part 10 is larger than the diameter in the trunk | drum 110 (refer FIG. 1 or FIG. 2) of the roll 100, and is 90 mm in this embodiment. Further, the height (length in the axis O direction) of the main body 10 is 55 mm in the present embodiment.

  A fitting portion 20 is formed on one end side of the main body portion 10 so as to be surrounded by the surface of the base end portion 11 and the cylindrical wall portion 12. The fitting portion 20 has a concave portion 21 having a substantially circular cross section around the axis O of the main body portion 10, and the concave portion 21 is a portion where the edge of the roll 100 is fitted. Function as. The height of the recessed portion 21 (the length in the direction of the axis O) is equal to the width of the wall portion 12 (that is, the height of the wall portion 12 viewed from the base end portion 11), and is 35 mm in this embodiment. Further, the diameter L2 in the recessed portion 21 is a length obtained by subtracting the thickness of the wall portion 12 from the outer diameter L1, and is substantially equal to the diameter in the neck portion 120 (see FIG. 1 or FIG. 2) of the roll 100. Is 77 mm.

  Moreover, the fitting part 20 has the latching | locking part 22 which protruded and formed over the perimeter from the recessed part 21 toward the radial inside direction in the position along the opening edge of the recessed part 21. As shown in FIG. Specifically, the locking portion 22 is a protrusion formed around the inner peripheral surface of the cylindrical wall portion 12 and is formed at the opening edge of the fitting portion 20. That is, the locking portion 22 has a shape that protrudes toward the outer peripheral surface of the roll 100 (see FIG. 1) fitted in the recessed portion 21, and is formed on the inner surface of the recessed portion 21. It has a function of locking the roll 100. In addition, the protrusion width | variety (height of radial inside direction) of the latching | locking part 22 is a magnitude | size which is the extent which does not inhibit fitting / removal of the neck part 120 of the roll 100 with respect to the recessed part 21, and is about 3 mm in this embodiment. . And the diameter L3 of the internal peripheral surface in the site | part in which the latching | locking part 22 was formed among the recessed parts 21 becomes the length which subtracted the protrusion width | variety of the latching | locking part 22 from the diameter L2, and is 71 mm in this embodiment. .

  On the base end surface 11 a of the main body portion 10, an accommodating portion 30 having a volume that can accommodate the wireless IC tag 80 is formed. Specifically, the accommodating portion 30 is formed such that a part of the surface of the base end portion 11 opposite to the surface on which the wall portion 12 is formed is depressed, and the axis portion O of the main body portion 10 is the center. The cross section is a concave portion having a substantially circular shape with a small diameter. The height (length in the direction of the axis O) of the accommodating portion 30 is about half of the width of the base end portion 11 (that is, the thickness of the base end portion 11), and is 12 mm in this embodiment.

  As described above, the fitting part 20 and the accommodating part 30 are formed on both ends of the main body part 10 respectively. The fitting part 20 and the accommodating part 30 are physically separated by the thickness of the base end part 11. Have a structured. That is, when the neck portion 120 of the roll 100 is fitted into the fitting portion 20, the portion of the base end portion 11 sandwiched between the fitting portion 20 and the accommodation portion 30 is a wireless IC tag accommodated in the accommodation portion 30. This is a buffer unit 50 that separates the neck 120 from 80 and prevents physical contact between the wireless IC tag 80 and the neck 120.

  Here, since the roll 100 of this embodiment is made of iron, which is a conductive metal, when the wireless IC tag 80 and the neck 120 are close to each other, the wireless signal related to the wireless IC tag 80 is reflected. As a result, writing or / and reading to the wireless IC tag 80 may be hindered. On the other hand, when the roll end cover 1 is attached to the roll 100 and the wireless communication with the wireless IC tag 80 is performed, the buffer portion 50 of the present embodiment reflects the radio wave at the neck portion 120 of the roll 100. It has a function to prevent the wireless communication from being hindered.

  In other words, the storage unit 30 is in a position where information can be written to and / or read from the wireless IC tag 80 even when the roll end cover 1 is attached to the roll 100 (in other words, information writing to the wireless IC tag 80 or / And a position where reading is not hindered). Specifically, the accommodating portion 30 is configured such that the roll 100 fitted in the fitting portion 20 does not electrically affect the wireless IC tag 80 by the buffer portion 50 and the neck portion 120. They are formed apart. As a result, even when the roll end cover 1 is attached to the roll 100, information can be written to and / or read from the wireless IC tag 80 in the housing unit 30.

  The main body portion 10 is formed with an air escape hole 40 that penetrates the base end portion 11 substantially parallel to the axis O direction and communicates the recessed portion 21 of the fitting portion 20 with the other end surface of the main body portion 10. ing. The air escape hole 40 causes the air in the recessed portion 21 to flow outside when the roll 100 is fitted into the recessed portion 21, and the air from the outside to the recessed portion 21 when the roll 100 is extracted from the recessed portion 21. Is caused to flow, so that the roll 100 is smoothly attached to and detached from the recessed portion 21.

  The wireless IC tag 80 is a non-contact type storage medium that can be written to and / or read by wireless communication, and stores at least ID information unique to each wireless IC tag. The wireless IC tag 80 is a small and light coin-type IC tag that can be easily put into and out of the accommodating portion 30. Note that the wireless IC tag 80 of this embodiment has a thin disk shape with a diameter of 22 mm and a thickness of 4 mm, and the frequency used is 13.56 MHz and the memory capacity is 112 bytes.

  The sealing lid 90 is a lid member that seals the opening of the housing portion 30 so that the wireless IC tag 80 does not protrude from the housing portion 30 after the wireless IC tag 80 is housed in the housing portion 30. Therefore, the sealing lid 90 has a larger disk shape than the wireless IC tag 80, and is the same as the opening cross section of the housing portion 30 or slightly larger than the opening cross section so as to be tightly fitted to the housing portion 30. It has a large diameter, and in this embodiment, the diameter of the sealing lid 90 is 30 mm.

  The sealing lid 90 is made of a transparent or translucent non-conductive material (here, rubber having transparency or translucency). The reason why the sealing lid 90 is made of a transparent material having translucency is that the operator removes the sealing lid 90 each time the sealing lid 90 is attached to the opening of the accommodating portion 30. This is because it is possible to confirm whether or not the wireless IC tag 80 is housed in the housing unit 30. For this reason, the sealing lid 90 only needs to have transparency at least enough to confirm the presence or absence of the wireless IC tag 80 in the housing portion 30. The reason why the sealing lid 90 is made of a non-conductive material is to prevent the writing or / and reading of information from being performed on the wireless IC tag 80 in the housing unit 30. Furthermore, the sealing lid 90 is preferably made of an elastic material with poor flexibility (here, rubber with low elasticity). Thereby, it becomes easy to attach / detach the sealing lid 90 to / from the opening of the accommodating portion 30, and it is also possible to prevent a problem that the projection material collides and causes damage or breakage during shot blasting.

  Here, the internal structure of the accommodating part 30 is demonstrated in detail. As shown in FIG. 3, the accommodating portion 30 has a substantially circular opening edge 31 formed in the base end surface 11 a, and the diameter of the opening edge 31 is slightly larger than the diameter of the wireless IC tag 80 and It is slightly smaller than the diameter of the sealing lid 90. In the present embodiment, the diameter L11 of the opening edge 31 is 26 mm.

  Moreover, in the accommodating part 30, it is the diameter centering on the axis line O toward the fitting part 20 side (it is a right direction side in FIG. 3, and is hereafter called "an axial direction O-axis side") from this opening edge 31. Is gradually increased (in other words, the opening cross section of the accommodating portion 30 is gradually increased), the inner peripheral surface thereof is inclined with respect to the direction of the axis O. And the site | part enclosed by the inclined surface with respect to the axis line O in the accommodating part 30 is the cover holding | maintenance part 32 by which the sealing lid | cover 90 is engage | inserted. In the accommodating portion 30, the length in the axis O direction occupied by the lid holding portion 32 is slightly larger than the thickness of the sealing lid 90. In the present embodiment, the diameter L12 at the portion where the inner diameter is the largest in the lid holding portion 32 is 30 mm, which is substantially equal to the diameter of the sealing lid 90. That is, the lid holding part 32 is formed so as to have a shape and size capable of sandwiching the sealing lid 90 in the radially inward direction, which will be described in detail later.

  Further, in the accommodating portion 30, a tag holding portion 33 that is a recessed portion having a smaller diameter than the lid holding portion 32 is formed from the lid holding portion 32 toward one end side in the axis O direction. That is, inside the housing portion 30, the lid holding portion 32 that expands in diameter as viewed from the opening edge 31 and the tag holding portion 33 that has a small-diameter cylindrical shape are formed by a step formed on the inner peripheral surface of the housing portion 30. It is connected continuously. In the accommodating portion 30, the length in the axis O direction occupied by the tag holding portion 33 is substantially equal to the thickness 4 mm of the wireless IC tag 80, and the diameter of the tag holding portion 33 is substantially equal to the diameter 22 mm of the wireless IC tag 80. That is, the tag holding unit 33 is formed to have substantially the same shape and size as the external shape of the wireless IC tag 80.

  Next, a specific mode in which the roll end cover 1 is attached to and detached from the roll 100 and the wireless IC tag 80 is attached to and detached from the roll end cover 1 will be described with reference to FIG. When the roll end cover 1 is attached to the roll 100, the axis of the roll 100 and the axis of the main body 10 of the roll end cover 1 substantially coincide.

  By the way, the roll 100 to which the roll end cover 1 is attached and detached includes the trunk portion 110 and the neck portion 120 as described above. And the outer diameter L4 of the trunk | drum 110 is smaller than the outer diameter L1 (refer FIG. 3) of the main-body part 10, and is smaller than the inner diameter (specifically diameter L2 of the recessed part 21, see FIG. 3) of the main-body part 10, In this embodiment, it is 85 mm. Further, the outer diameter L5 of the neck portion 120 is the same as the diameter L2 of the recessed portion 21 or slightly smaller than the diameter L2 of the recessed portion 21 and larger than the diameter L3 (see FIG. 3) of the locking portion 22. In this embodiment, it is 77 mm.

  First, when the operator attaches the wireless IC tag 80 to the roll 100, the operator inserts the wireless IC tag 80 into the housing unit 30 through the opening edge 31, and attaches the wireless IC tag 80 to the tag holding unit 33. To fit. As described above, since the tag holding unit 33 is formed to have substantially the same shape and size as the external shape of the wireless IC tag 80, when the wireless IC tag 80 is fitted to the tag holding unit 33, the tag holding unit 33 is fixed to some extent. . However, if the roll end cover 1 is rotated or vibrated, the wireless IC tag 80 may be naturally detached from the tag holding unit 33 and may jump out of the housing unit 30.

  Therefore, after fitting the wireless IC tag 80 to the tag holding portion 33, the operator inserts the sealing lid 90 into the lid holding portion 32, so that the wireless IC tag 80 is detached from the tag holding portion 33 or the accommodating portion. It is prevented from jumping out from 30. Here, in the lid holding part 32, the diameter L12 (see FIG. 3) on the tag holding part 33 side is substantially equal to the diameter of the sealing lid 90, while the diameter L11 on the opening edge 31 side is the diameter of the sealing lid 90. Smaller than. Therefore, on the inner peripheral surface of the lid holding part 32, a larger elastic pressure is applied to the outer peripheral surface of the sealing lid 90 at a portion closer to the opening edge 31, and the sealing lid 90 is sandwiched. Further, the sealing lid 90 is urged toward one end side in the axis O direction by the elastic pressure applied from the lid holding portion 32. Thereby, even if rotation or vibration occurs in the roll end cover 1, the sealing lid 90 moves to the other end side in the axis O direction (left direction side in FIG. 4) and falls off the lid holding portion 32. In addition to preventing problems, the wireless IC tag 80 is more stably fixed by the sealing lid 90 pressing the wireless IC tag 80 against the tag holding portion 33.

  On the other hand, when the operator removes the wireless IC tag 80 from the roll 100, external pressure is applied to the main body portion 10 to widen the opening area of the opening edge 31 of the housing portion 30, and the sealing lid 90 is taken out of the housing portion 30. . Thereafter, the wireless IC tag 80 may be removed from the tag holding unit 33 and the wireless IC tag 80 may be taken out of the housing unit 30.

  Next, when the operator attaches the roll end cover 1 to the roll 100, the fitting portion 20 of the roll end cover 1 is brought close to the neck portion 120 of the roll 100, and the neck portion 120 is pushed into the recessed portion 21. Apply external pressure as shown. Here, the outer diameter L5 of the neck portion 120 is slightly larger than the diameter L3 of the inner peripheral surface of the recessed portion 21 where the locking portion 22 is formed, and the locking portion 22 is formed on the outer peripheral surface of the neck portion 120. It will abut. However, since the main body portion 10 has flexibility and the wall portion 12 is also deformed according to the external pressure, the locking portion 22 has a rounded protruding shape at the tip. However, if a predetermined amount of external pressure is applied, the neck 120 can be fitted into the recessed portion 21 relatively smoothly.

  In the state where the fitting part 20 of the roll end cover 1 is attached to the neck part 120 of the roll 100, the fitting part 20 makes substantially the entire neck part 120 (specifically, a part of the neck part 120 excluding the groove part 121). ), The neck 120 is stably held and protected from the outside.

  In addition, since the diameter L2 of the recessed portion 21 and the outer diameter L5 of the neck portion 120 are substantially equal inside the fitting portion 20, the inner peripheral surface 21a of the recessed portion 21 is in close surface contact with the outer peripheral surface of the neck portion 120. Thus, the neck 120 is held on the entire outer periphery. Further, the inner bottom surface 21b of the recessed portion 21 abuts on the distal end surface of the neck portion 120 and restricts the movement of the neck portion 120 toward the other end side in the axis O direction. Further, the locking portion 22 abuts on the outer peripheral surface of the neck portion 120, and the neck portion 120 is locked by elastic pressure directed radially inward, thereby restricting the movement of the neck portion 120 toward one end in the axis O direction. That is, when the roll end cover 1 is attached to the roll 100, the entire neck portion 120 is tightly held inside the fitting portion 20, so that the neck portion 120 is not exposed to the outside and is not easily detached from the fitting portion 20. have.

  As described above, when the operator attaches the roll end cover 1 to the roll 100, the neck 120 of the roll 100 is protected from the outside by the roll end cover 1. At the same time, the wireless IC tag 80 held by the roll end cover 1 is physically associated (linked) to the roll 100. Thereby, the worker can uniquely identify the plurality of rolls 100 by reading the unique identification information of the wireless IC tag 80.

  On the other hand, when the worker removes the roll end cover 1 from the roll 100, the worker deforms the wall portion 12 of the main body portion 10 to release the locking of the neck portion 120 by the locking portion 22, and the fitting portion 20. The external pressure may be applied so that the neck 120 is pulled out from the head. When the roll end cover 1 is removed from the roll 100, the physical association (linking) of the wireless IC tag 80 with the roll 100 is released.

  Next, structural features of the roll 100 to which the roll end cover 1 is attached will be described with reference to FIG. FIG. 5 is a schematic plan view when a plurality of rolls 100 each having the roll end cover 1 attached thereto are arranged substantially in parallel. In addition, in FIG. 5, the three rolls 100a-100c with which the roll end cover 1 was attached are illustrated, The roll end cover 1 attached to the both-ends edge part of each roll 100a-100c is each roll end cover 1a. ˜1c.

  As shown in FIG. 5, the roll 100 a and the roll 100 b are arranged in parallel so that the respective axes are substantially parallel and the positions in the respective axial directions are approximately the same. When either of the roll 100a and the roll 100b moves in a direction in which they are close to each other, the roll 100a and the roll 100b are adjacent to each other. At this time, the roll end cover 1a and the roll end cover 1b come into contact with each other at both edge portions of the roll 100a and the roll 100b. As a result, a gap having a predetermined width (width h1) is formed between the body 110a and the body 110b, and interference between the body 110a and the body 110b is avoided. The size of the width h1 corresponds to the sum of the values obtained by subtracting the radius L4 / 2 of the body 110 from the radius L1 / 2 of the main body 10 for the two rolls 100.

  Further, the roll 100b and the roll 100c are arranged in parallel in a state in which the respective axes are substantially parallel while the positions in the respective axial directions are shifted. When either of the roll 100b and the roll 100c moves in a direction in which they are close to each other, the roll 100b and the roll 100c are adjacent to each other. At this time, the roll end cover 1b comes into contact with the body part 110c of the roll 100c at one end side in the axis O direction of the roll 100b, and the roll end cover 1c contacts the body part 110b of the roll 100b at the other end side in the axis O direction of the roll 100c. Abut. A gap having a predetermined width (width h2) is formed between the roll end cover 1b and the body portion 110c (that is, between the roll end cover 1c and the body portion 110b). The size of the width h2 corresponds to the total value of the values obtained by subtracting the outer diameter L4 of the body 110 from the outer diameter L1 of the main body 10 of one roll 100 (that is, approximately half of the width h1). .

  As described above, when a plurality of rolls 100 to which the roll end cover 1 is attached are arranged in parallel, even if the rolls 100 move in the direction in which they are close to each other and the rolls 100 are adjacent to each other, they are attached to the roll 100. The roll end cover 1 forms a gap having a predetermined width (width h1, h2) between the body portions 110. This is because the outer diameter L1 of the roll end cover 1 (specifically, the main body portion 10) is larger than the outer diameter L4 of the roll 100 (specifically, the trunk portion 110).

  Therefore, even if the roll 100 to which the roll end cover 1 is attached is arranged on a plane in a freely rotatable state, the body portions 110 are not in direct contact with each other, and the roll surface is scratched or damaged. Is prevented. Since the main body 10 of the roll end cover 1 is made of a flexible elastic body (here, rubber) as described above, the roll end cover 1 is in contact with the body 110 of the roll 100. Even in such a case, the roll surface of the body 110 is not damaged or damaged.

  Note that FIG. 5 illustrates the case where a plurality of rolls 100 are arranged in parallel for easy understanding. However, if the outer diameter L1 of the roll end cover 1 is larger than the outer diameter L4 of the roll 100, the plurality of rolls 100 is used. The same effects as described above can be obtained even when the rolls are arranged so as to cross each other or when rolls having different overall lengths and diameters are used as the plurality of rolls 100.

  Next, a specific example in which a plurality of rolls 100 each having a roll end cover 1 attached thereto is used in a rolling mill and a roll shop will be described with reference to FIG. FIG. 6 is an external perspective view of a pallet 200 on which a plurality of rolls 100 are mounted.

  When the roll surface used in the rolling mill is worn by rolling a workpiece such as metal, the roll 100 is replaced with a new roll whose roll surface has been polished or / and blasted. Therefore, although not shown, the roll shop attached to the rolling mill is equipped with a roll polishing device for polishing new rolls immediately after purchase, old used rolls, etc. There are also provided a dull processing apparatus for carrying out the above, an apparatus for carrying out and exchanging these rolls, and the like.

  By the way, various operations such as storage and conveyance of the plurality of rolls 100 are performed with the pallet 200 on which a specified number of rolls 100 can be mounted as one unit. For example, when shot blasting is performed on the roll 100 with a dull processing machine, the pallet 200 on which a specified number of rolls 100 are mounted is conveyed to the dull processing machine, and the dull processing machine has a plurality of pallets 200 mounted on the pallet 200. For example, shot blasting of the rolls 100 one by one. In addition, in the pallet 200 of this embodiment, ten rolls 100 can be mounted as a specified number.

  As shown in FIG. 6, the pallet 200 has a base 201 in which four columnar reinforcing bars are connected in a frame shape, and ten rolls 100 can be placed in parallel on the base 201. Yes. Note that the pedestal 201 has a longitudinal left and right direction parallel to the axial direction of the roll 100 when a plurality of rolls 100 are mounted, and the lateral length of the pedestal 201 is greater than the axial length of the roll 100. Is also slightly larger.

  In the pedestal 201, two roll stoppers 202 that can be attached to and detached from the upper surface side of the columnar reinforcing bar can be installed on each of the two columnar reinforcing bars arranged along the longitudinal direction of the pallet 200. Yes. The roll stopper 202 is a rod-like member that stands upward from the columnar reinforcing bar when attached to the upper surface side of the columnar reinforcing bar of the pedestal 201, and the rotation direction of the roll 100 placed on the pedestal 201 (that is, For example, when the pallet 200 is transported, the roll 100 has a function of preventing the roll 100 from dropping from the pedestal 201. On the other hand, for example, when the roll 100 is used in a rolling mill or the like, the roll stopper 202 is removed from the pedestal 201 so that the roll 100 can be easily moved from the pallet 200 while rotating about the axis. Each roll stopper 202 is provided at a position where it abuts on the body 110 of the roll 100 placed on the pedestal 201, and an elastic member that does not cause damage or damage even if it contacts the body 110 (for example, , Rubber).

  In addition, two thin plate-like support rails 203 are installed on the base 201 so as to straddle two columnar reinforcing bars arranged along the longitudinal direction of the pallet 200. These support rails 203 are provided at positions corresponding to the groove portions 121 of the roll 100 placed on the pedestal 201. Here, when the roll end cover 1 is attached to the roll 100, a gap portion is formed between the main body portion 10 and the trunk portion 110 (see FIG. 4). When a plurality of rolls 100 are mounted on the pallet 200, the two support rails 203 are positioned so that the two support rails 203 enter the gaps between the main body 10 and the body 110 in each roll 100, and each roll is placed on the base 201. The operation of placing 100 is performed. When the plurality of rolls 100 are placed on the pedestal 201 in this way, each roll 100 is supported by the respective groove portions 121 by the two support rails 203. As a result, the roll 100 placed on the pedestal 201 is restricted from moving in the axial direction (that is, the left-right direction of the pallet 200) by the two support rails 203. And the fall of the roll 100 from the pallet 200 is prevented. Note that, like the roll stopper 202, the support rail 203 is also made of an elastic member (for example, rubber) that does not cause damage or damage even if it contacts the groove portion 121 or the body portion 110 of the roll 100.

  Furthermore, a wireless IC tag 210 that is a non-contact type storage medium that can be written and / or read by wireless communication is attached to the base 201. The wireless IC tag 210 stores at least ID information unique to each wireless IC tag, and the unique ID information functions as information for uniquely identifying the pallet 200. Note that the wireless IC tag 210 has a side surface of the base 201 that allows easy wireless communication with the wireless IC tag 210 so that various types of information can be written and / or read even when attached to the pallet 200 being transported. It is provided at the site.

  Here, the one aspect | mode which manages the information regarding the roll 100 used for a rolling mill and a roll shop is demonstrated. First, when a roll 100 is newly purchased, the roll 100 is mounted on the pallet 200 after the roll end cover 1 is attached thereto. In addition, although the roll end cover 1 is attached to the both ends edge of each roll 100, the radio | wireless IC tag 210 is hold | maintained at any one roll end cover 1. FIG.

  Then, the worker holds the wireless IC tag 80 with a portable terminal (hereinafter referred to as a reader / writer terminal) incorporating a reader / writer capable of performing writing or / and reading with the wireless IC tag by wireless communication. The unique ID information stored in the wireless IC tag 80 is read close to the roll end cover 1. The reader / writer terminal is connected to a computer (hereinafter referred to as a management device) for managing information related to the roll 100 by wireless or wired, and ID information read from the wireless IC tag 80 is stored in the management device. Remembered. The ID information stored in the management device functions as identification information (that is, role identification ID) for identifying each roll 100 to which the roll end cover 1 is attached.

  Further, the operator brings the reader / writer terminal close to the wireless IC tag 210 of the pallet 200 on which the roll 100 is mounted, and stores unique ID information (that is, a pallet identification ID) stored in the wireless IC tag 210. read out. Then, in the management apparatus, this pallet identification ID is stored in association with the role identification ID. Thereby, the pallet 200 on which the roll 100 is mounted is associated with the roll 100 in the management apparatus.

  The management apparatus uses the roll identification ID as a key and, in addition to the pallet identification ID, roll-related information having data items such as the current position of the roll, the current usage state, and the current roll diameter as time data. Centralized management of affiliates. Therefore, for example, in the case of roll-related information of the new roll 100, the roll current position “roll storage”, the current use state “unused”, the current roll diameter “ Data content such as “77 mm”.

  In the roll shop, each time a polishing operation with a roll polishing apparatus or a shot blasting operation with a dull processing machine is performed with a plurality of rolls 100 mounted on the pallet 200 as a unit, the latest information on the roll 100 is obtained. The role related information is registered in the management apparatus. For example, when a polishing operation is performed by the roll polishing apparatus, when the operator reads the roll identification ID from the roll end cover 1 of the roll 100 to be polished by the reader / writer terminal, the current position of the roll is “ “Roll polishing device” and roll-related information whose current use state is updated to “in polishing work” are registered as the latest history data.

  As described above, since the management apparatus centrally manages the role-related information of each role 100, for example, when the operator wants to know detailed information about the specific role 100, the roll end of the specific role 100 is determined. If the role identification ID is read from the cover 1, the corresponding role-related information can be searched by using the role identification ID as a key in the management device. Then, by referring to this role-related information, not only detailed information regarding the current role 100 but also past history data regarding the role 100 can be referred to. Thus, the information regarding the roll 100 used in a rolling mill or a roll shop can be managed efficiently and accurately only by attaching the roll end cover 1 to the roll 100.

  Furthermore, conventionally, the operator also determines whether or not the roll 100 used in the rolling mill has an optimum roll diameter based on experience. However, in this embodiment, the operator can grasp the current roll diameter, the past use history, and the like by referring to the roll related information of each roll 100 as necessary. Therefore, it is possible to accurately determine whether or not the roll 100 should be used in a rolling mill and whether or not the roll 100 should be discarded or polished without depending on the experience and skill of the operator, thereby reducing the burden on the operator. Working efficiency can be improved.

  By the way, when the roll surface of the roll 100 worn in the roll polishing apparatus (specifically, the outer peripheral surface of the body portion 110) is polished, the outer diameter L4 of the body portion 110 is reduced. And when the outer diameter L4 of the trunk | drum 110 becomes a predetermined amount (for example, 3 mm), the outer peripheral surface of the neck part 120 may also be grind | polished according to this and the outer diameter L5 may become small. However, when the outer diameter L5 of the neck portion 120 is significantly smaller than the diameter L2 of the recessed portion 21 of the roll end cover 1 by this polishing operation, the neck portion 120 cannot be tightly fitted into the recessed portion 21, There is a problem that the roll end cover 1 is easily removed.

  Therefore, in this embodiment, the roll end cover 1 having a plurality of patterns with different diameters L2 of the recessed portions 21 is prepared in advance, and the diameter L2 of the recessed portions 21 that substantially matches the outer diameter L5 of the neck portion 120 of the roll 100 is prepared. The roll end cover 1 having the above is attached to the roll 100. In addition, the roll end cover 1 having such a plurality of patterns is configured such that the thickness of the wall portion 12 of the main body portion 10 is increased or decreased in the radial direction so that the diameters L2 of the recessed portions 21 are different from each other. Can do. Further, the roll end cover 1 having a plurality of patterns has a configuration in which only the thickness of the wall portion 12 of the main body portion 10 is increased or decreased in the radial direction. L1 can be the same.

  Further, when performing dull processing by shot blasting on the roll 100 in the dull processing machine, since the neck portion 120 of the roll 100 is protected by the roll end cover 1, the projection material is exposed to the outer periphery of the trunk portion 110 by shot blasting. A problem that the projection is applied only to the surface and the projection material hits the outer peripheral surface of the neck 120 to cause scratches or damage is prevented. Moreover, since the main-body part 10 and the sealing lid 90 of the roll end cover 1 are comprised with the rubber | gum which is an elastic body, even if a projection material hits, a damage | wound and damage can be suppressed lightly. In addition, although heat is generated when the projection material collides with the roll 100 during shot blasting, the main body portion 10 of the roll end cover 1 is made of heat-resistant rubber, so that it does not deform. Further, when the roll 100 is rotated by shot blasting, the roll end cover 1 may be removed due to the centrifugal force. However, the end edge of the roll 100 is closely fitted in the recessed portion 21 and the locking portion 22 is used. Since it is locked, even if such centrifugal force is applied, the roll end cover 1 is prevented from falling.

  As described above, the roll end cover 1 of the present embodiment holds the wireless IC tag 80 capable of storing information on the roll 100 used in the rolling mill with the non-conductive main body 10. is there. And the main-body part 10 has the fitting part 20 which can be freely attached or detached with respect to the edge part of the roll 100, The roll end cover 1 can be attached to the roll 100 by this fitting part 20. FIG. Further, the main body 10 has a housing 30 that can accommodate the wireless IC tag 80, and the wireless IC tag 80 can be disposed in the housing 30. Then, the storage unit 30 can write or / and read information related to the roll 100 by wireless communication with respect to the wireless IC tag 80 stored in the storage unit 30 (specifically, the buffer unit 50 uses the roll 100 to read and write information). At a position spaced apart from the neck portion 120).

  Thereby, the roll end cover 1 can be attached to the end edge portion of the roll 100 in a state where the wireless IC tag 80 capable of storing the roll related information is held. And the main-body part 10 has a function which separates the radio | wireless IC tag 80 from the roll 100 which reflects an electromagnetic wave by being comprised with the substance which lets an electromagnetic wave pass. Therefore, even if the roll 100 used in the rolling mill is made of a conductive metal, information can be written to and / or read from the wireless IC tag 80 by wireless communication. Therefore, each roll 100 is uniquely identified by simply attaching the roll end cover 1 to each of a plurality of rolls used in a rolling mill and a roll shop, and referring to unique identification information stored in the wireless IC tag 80. Can be identified.

  When the management device centrally manages the detailed information (current position, current usage status, past usage history, current roll diameter, etc.) of each roll 100, the roll attached to each roll 100 The wireless IC tag 80 held in the end cover 1 is referred to, and detailed information of each roll 100 may be registered as appropriate based on identification information unique to the wireless IC tag 80 (that is, role identification information). Thereby, when an operator wants to know the detailed information about a specific roll 100, the detailed information can be obtained simply by making the management device search using the identification number of the roll 100 as a key. It is possible to efficiently and accurately manage information about the roll 100 used in the roll shop.

  Further, the main body 10 forms a cylindrical body that is substantially coaxial with the axis of the roll 100 in a state where the fitting portion 20 is fitted to the end edge of the roll 100. That is, when the roll end cover 1 is attached to the roll 100, the axis of the main body 10 forming a cylindrical body and the axis of the roll 100 having a substantially cylindrical shape substantially coincide with each other. And although the outer diameter L1 of the main-body part 10 is larger than the largest diameter part in the roll 100, generally the largest diameter part in the roll 100 contact | abuts to workpieces, such as a metal, when used for a rolling mill. Since it is the trunk | drum 110, it can be said that the outer diameter L1 of the main-body part 10 is larger than the outer diameter L4 in the trunk | drum 110 of a roll.

  As a result, when the roll end cover 1 is attached to the end edge of the roll 100, the main body 10 protrudes most radially outward when viewed from the axis of the main body 10 and the roll 100. Therefore, even when the plurality of rolls 100 are arranged in parallel, even if the adjacent rolls 100 move in the direction in which they are close to each other, the body 110 of each roll 100 is attached to each roll 100 before contacting each other. The roll end cover 1 abuts on the body 110 of the adjacent roll 100 or the roll end cover 1. Therefore, even if a plurality of rolls 100 are arranged adjacent to each other, it is possible to prevent the body portions 110 of the rolls 100 from coming into contact with each other and causing damage or damage to the roll surface.

  The main body 10 is integrally formed of an elastic material (here, rubber) and has flexibility. By integrally forming the main body 10 with an elastic material, the structure of the main body 10 can be simplified, and the manufacturing process and product cost of the roll end cover 1 can be reduced. Moreover, since the main-body part 10 has flexibility, while being able to make attachment or detachment to the roll 100 easy, damage by the shot blasting in a dull processing machine can be prevented. In order to prevent a problem that the main body is deformed due to heat generation of the roll 100 at the time of shot blasting and the fitting portion 20 is detached from the end edge of the roll 100, this elastic material has a predetermined heat resistance. It is desirable to have the property.

  Moreover, the edge part of the roll 100 is the neck part (neck part) 120 which makes a smaller diameter than the trunk | drum 110, and is a site | part which is not used for the rolling of the workpiece in a rolling mill. For example, the neck 120 functions as a portion that is gripped when the roll 100 is incorporated into a rolling mill, or functions as a portion that is rotatably supported by the rolling mill. When the fitting portion 20 is fitted to the end edge portion of the roll 100, substantially the entire neck portion 120 is enveloped by the fitting portion 20. In other words, in a state where the roll end cover 1 is attached to the roll 100, almost the entire neck portion 120 is protected from the outside by the roll end cover 1, so that, for example, projection is performed on the neck portion 120 even during shot blasting. It is possible to prevent the material from colliding and prevent the neck 120 from being damaged or broken.

  Further, the fitting portion 20 has substantially the same diameter and substantially the same shape as the end edge portion of the roll 100 so as to be tightly fitted to the end edge portion of the roll 100, and substantially the entire end edge portion of the roll 100. Has a recessed portion 21 having a depth (a distance from the opening edge to the inner bottom) that can be inserted. And it has the latching | locking part 22 protrudingly formed toward the outer peripheral surface of the roll 100 fitted by the recessed part 21, and the distance to the latching | locking part 22 seeing from the axis line of the main-body part 10 is the inside of the recessed part 21. It is slightly smaller than the distance to the side. Therefore, when the roll 100 is fitted in the recessed portion 21, the roll 100 is locked on the inner surface of the recessed portion 21 by the pressing force applied from the locking portion 22 to the roll surface side. Thereby, even if vibration or rotational force is applied to the roll 100 by, for example, shot blasting, it is possible to prevent a problem that the roll end cover 1 is detached from the roll 100.

  In addition, although the latching | locking part 22 is formed over the perimeter in the inner surface of the recessed part 21 (an inner peripheral surface if the recessed part 21 is cylindrical), it is partially on the inner surface of the said recessed part 21 May be formed. Moreover, although the cross-sectional shape and protrusion shape of the latching | locking part 22 can also be formed arbitrarily, as for the protrusion width | variety of this latching | locking part 22, an operator intentionally inserts and detaches the roll 100 with respect to the recessed part 21 so that it may mention later. It is suitable that it can be performed by adding

  Moreover, the wireless IC tag 80 accommodated in the accommodating part 30 is sealed, and at least the wireless IC tag 80 accommodated in the accommodating part 30 is provided with a light-transmitting sealing lid 90. According to this, the trouble that the wireless IC tag 80 is removed from the roll end cover 1 can be prevented, and the wireless IC accommodated in the accommodating portion 30 even in the state of being sealed with the sealing lid 90. The tag 80 can be visually recognized. Therefore, it is possible to confirm whether or not the wireless IC tag 80 is accommodated in the accommodating portion 30 without removing the sealing lid 90 each time, and the burden on the operator can be reduced.

  In addition, although this invention is described in said preferable embodiment, this invention is not restrict | limited only to it. Various embodiments are possible without departing from the spirit and scope of the invention.

  For example, in the present embodiment, the case where the main body portion 10 of the roll end cover 1 has a cylindrical shape is illustrated, but the shape and size of the main body portion 10 can be arbitrarily designed. Here, the example which changed the shape of the main-body part 10 of the roll end cover 1 is shown in FIG. FIG. 7 is an external view of a roll 100 to which another form of roll end cover 1 is attached. The roll end cover 1 shown in FIG. 7 is configured in an octagonal column shape in which a cross section perpendicular to the axial direction forms an octagonal shape. According to this, when the plurality of rolls 100 are mounted on the pallet 200, the roll end cover 1 restricts the movement of the roll 100 in the rotation direction even if the base 201 does not have the roll stopper 202. Therefore, mutual interference between the body portions 110 of the roll 100 can be prevented.

  Moreover, the shape and size of the fitting part 20 and the accommodating part 30 which the main-body part 10 of the roll end cover 1 has can also be changed suitably. That is, since the fitting part 20 should just be attachable with respect to the edge part of the roll 100, what is necessary is just to form according to the shape and magnitude | size of the edge part of the roll end cover 1. FIG. In addition, since the accommodation unit 30 only needs to accommodate the wireless IC tag 80, it may be formed in a shape or size that can accommodate at least the wireless IC tag 80 inside. Further, the wireless IC tag 80 is not limited to the coin type as in the present embodiment, but may be a stick type or a card type that can be accommodated in the accommodating unit 30, and the roll end cover 1 also has a use frequency and a storage capacity. What is necessary is just to select an optimal thing suitably according to the environment where is used.

  Further, instead of or in addition to centrally managing detailed information of each roll 100 by the management device, the wireless IC tag 80 held on the roll end cover 1 attached to each roll 100 is attached to the roll. 100 detailed information may be written by wireless communication. According to this, when an operator wants to know detailed information about a specific roll 100, the details of the roll 100 are wirelessly communicated from the wireless IC tag 80 held on the roll end cover 1 attached to the roll 100. Information can be directly read and referred to, and work efficiency is improved.

It is a typical perspective view for demonstrating the external appearance of a roll end cover and a roll. It is a typical perspective view for demonstrating the external appearance of a roll end cover and a roll seen from the direction different from FIG. It is side surface sectional drawing of a roll end cover. It is side surface sectional drawing of the state which attached the roll end cover with respect to the roll. It is a schematic plan view at the time of arrange | positioning the some roll with which the roll end cover was respectively attached substantially in parallel. It is an external appearance perspective view of the pallet in which the some roll was mounted. It is an external view of the roll with which the roll end cover of the other form was attached.
