Description

Belt accessories and belts with belt accessories

The present invention relates to a belt accessory and a belt provided with the belt accessory.

Generally, a flat belt having a flat conveyance surface is used as a conveyance belt used in a conveyance device that conveys paper sheets (for example, printing paper). Since the flat belt is in contact with the conveyed object in a surface contact, the conveyed object can be stably conveyed, but there is a problem that the flat belt meanders during traveling and comes off the pulley. Therefore, a guided conveyance belt is known in which a guide for preventing meandering is provided on a surface (pulley contact surface) on a side of the belt that contacts the pulley (for example, Patent Document 1). In addition, a profiled conveyance belt having a profile such as a crosspiece provided on the conveyance surface is known (for example, Patent Document 2). The profile prevents the conveyed product from falling from the conveying belt when the conveyed product is conveyed to a high place, for example. The guide attached to the pulley contact surface and the profile attached to the conveying surface are generally joined to the belt by adhesion or fusion.

When a guide or profile is joined to the belt by adhesion or fusion, the joint is harder than other places, especially when it is wound around a pulley, it is susceptible to bending fatigue and becomes a starting point for cracks in the belt. . Therefore, materials that are easy to fuse and bond are selected for the guide and profile, and the same material as the belt and a relatively low hardness (soft) that is compatible with the belt so as not to cause peeling or cracking due to running. ) Material must be selected. Therefore, the material of the guide and profile has been selected from limited materials. In addition, since the profile and guide cannot be removed, it is often difficult to determine the life of the joint because the state of the joint cannot be confirmed simply by observing the appearance.

In order to fix the guide or profile to the belt by bonding or fusing, a dedicated fusing machine, heat press and adhesive may be used, and a dedicated mold may be used as necessary. There was a problem that it was difficult to install. If the guide or profile can be easily attached to and detached from the belt, if a part of the guide or profile is damaged, it can be easily repaired.

(overall structure)
FIG. 1 is a perspective view showing a belt 1A according to the present embodiment. In FIG. 1, the x direction is the longitudinal direction (also referred to as the traveling direction), the y direction is the width direction, and the z direction is the thickness direction. A belt 1A shown in FIG. 1 includes a belt main body 2A and a belt accessory 10A. In FIG. 1, the belt body 2A is indicated by an imaginary line for convenience of explanation. For the belt main body 2A, an endless flat belt or a toothed belt formed of resin or rubber can be used. Although not shown in FIG. 1, a plurality of belt accessories 10A are provided at a predetermined pitch in the longitudinal direction x.

The belt accessory 10A includes a profile 12A as a contour addition body and a guide 14A as a fixed body. The belt accessory 10A may be made of the same material as the belt body 2A or may be formed of a different material. For example, the belt accessory 10A is made of a synthetic resin such as polyacetal, nylon, or polypropylene, or a metal such as brass, iron, stainless steel, or aluminum. The profile 12A and the guide 14A may be made of the same material or different materials.

The profile 12A has a plate-like profile body 20 and a female body 21 formed integrally with the profile body 20. The profile main body 20 has a rectangular shape that is long in the width direction y of the belt main body 2A, and has a first belt contact surface 22 that contacts the conveying surface of the belt main body 2A at the lower end in FIG. The profile 12A may have an engagement protrusion 29 that engages with the side surface of the belt body 2A. The engaging protrusions 29 are provided on both sides of the profile body 20 and protrude from the first belt contact surface 22.

The female main body 21 has a shape in which the thickness of the plate-shaped profile main body 20 is partially increased. The profile 12A reduces the amount of material by reducing the thickness of the profile body 20 excluding the female body 21.

As shown in FIG. 2, the female main body 21 is disposed at the center in the width direction y of the profile main body 20 and is provided so as to contact the first belt contact surface 22. The female main body 21 has a contour in which a triangular prism is tilted sideways. The female main body 21 is provided with an engaging female portion 16. The engaging female portion 16 is formed on the first belt contact surface 22 side of the female main body 21. The engaging female portion 16 may be formed by bending or cutting the profile body 20.

The engaging female portion 16 is disposed at the center in the width direction y of the first belt contact surface 22 and has an opening 24 formed in the front surface 33 of the profile body 20. When the front surface 33 of the profile body 20 is installed on the belt 1A, the front surface 33 is disposed on the longitudinal direction x side of the belt 1A. That is, the front surface 33 of the profile body 20 intersects the longitudinal direction x of the belt body 2A. Therefore, the engaging female portion 16 has an opening 24 on the surface of the female main body 21 that intersects the longitudinal direction x of the belt main body 2A.

The opening 24 penetrates the profile body 20 in the thickness direction. That is, the opening 24 penetrates from the front surface 33 to the back surface 35 of the profile body 20. Restricting surfaces 26 are formed on both sides of the opening 24. As shown in FIG. 3, the regulation surface 26 is a side surface of the opening 24 and is inclined in a direction in which the distance between the side surfaces gradually decreases from the front surface 33 to the back surface 35 of the profile body 20.

A pair of jaws 27 projecting from the side surface of the opening 24 toward the center is provided at the lower end of the opening 24 (FIG. 2). A guide surface 28 is provided at the tip of the jaw 27. The guide surfaces 28 have a constant distance between the tips of the jaws 27 from the front surface 33 to the back surface 35 of the profile body 20 and are parallel to each other (FIG. 3).

The guide 14A has an engaging male part 18 and a guide part 31 (FIG. 1). The guide 14A is integrated with the profile 12A when the engaging female portion 16 and the engaging male portion 18 are engaged.

As shown in FIG. 4, the guide 14A has a guide portion 31 and an engaging male portion 18 formed integrally. The guide portion 31 is formed in a trapezoidal shape, a rectangular shape, a semicircular shape, a V shape, a U shape, or the like in the longitudinal cross section. That is, the guide part 31 has a three-dimensional shape whose longitudinal section is the shape as described above. In the case of FIG. 4, the longitudinal cross-sectional shape of the guide part 31 is a trapezoid. As for the guide part 31, the engagement male part 18 is integrally formed on the 2nd belt contact surface 32 which is an upper surface. The second belt contact surface 32 is in contact with the pulley contact surface of the belt main body 2A.

The engaging male part 18 has a head 30, a shaft part 34, and a convex part 36. The shaft portion 34 has an upper end connected to the lower surface of the head 30 and a lower end connected to the upper surface of the convex portion 36. The head 30 has a trapezoidal shape in plan view, and has an inclined tapered portion 37 in which the distance between both side portions gradually decreases from the proximal end having the long side toward the distal end having the short side. A side surface of the head 30, that is, a surface of the tapered portion 37 is referred to as an insertion surface 38. The head 30 is connected to the second belt contact surface 32 via the shaft portion 34.

As shown in FIG. 5, the shaft portion 34 has parallel side surfaces in which the distance between the side portions is constant from the base end of the head 30 toward the tip of the head 30. A convex portion 36 is provided on the second belt contact surface 32. That is, the lower surface of the convex portion 36 is connected to the second belt contact surface 32. The convex portion 36 has a plate shape in which the length in the thickness direction z is the thickness (also referred to as “height”). The convex portion 36 has a shape other than a perfect circle in a plan view, and in the case of FIG. 5, has the same trapezoidal shape as the plan view of the head portion 30, and is arranged coaxially with the head portion 30. Less than the thickness of

(installation method)
Next, a method for attaching the belt accessory 10A to the belt main body 2A will be described. First, a belt body 2A as shown in FIG. 6 is prepared. The belt main body 2 A includes a conveyance surface 3 as one surface, a pulley contact surface 5 as another surface parallel to the conveyance surface 3, and a through hole 42 penetrating from the conveyance surface 3 to the pulley contact surface 5. That is, the belt main body 2A in which the trapezoidal through-hole 42 having the same shape as the planar shape of the head 30 is formed in the thickness direction z is prepared. The through hole 42 is formed such that the short side and the long side are parallel to the width direction y. Although omitted in FIG. 6, a plurality of through holes 42 are formed at a predetermined pitch in the longitudinal direction x. The plurality of through holes 42 are arranged in a line along the longitudinal direction x of the belt main body 2A. In the case of FIG. 6, there is one through hole 42 in the width direction y.

Next, as shown in FIG. 7, the guide 14 A is disposed on the pulley contact surface 5 side of the belt body 2 A, the head 30 is passed through the through hole 42, and the convex portion 36 is fitted into the through hole 42. Since the trapezoidal convex part 36 fits into the same trapezoidal through-hole 42 in plan view, the guide 14A is fixed to the belt body 2A in the rotation direction with the thickness direction of the belt body 2A as the rotation axis.

Subsequently, as shown in FIG. 8, the profile 12 A is arranged on the transport surface 3 with the front surface 33 facing the head 30. The opening 24 is disposed on the surface of the female main body 21 that intersects the longitudinal direction x. By sliding the profile 12A in the longitudinal direction x, the head 30 is inserted into the opening 24 while 34 contacts the guide surface 28 (FIG. 9). When the insertion surface 38 of the head 30 inserted into the opening 24 comes into contact with the restriction surface 26, the engagement male portion 18 and the engagement female portion 16 are engaged, and the profile 12A and the guide 14A are integrated ( FIG. 10).

At this time, the jaw 27 is in contact with the lower surface of the head 30. The first belt contact surface 22 of the profile 12A is in contact with the conveying surface 3, and the second belt contact surface 32 of the guide 14A is in contact with the pulley contact surface 5 at the periphery of the through hole 42. The belt accessory 10A is attached to the belt body 2A by sandwiching the belt body 2A in the thickness direction z by the profile 12A and the guide 14A. The belt 1 A obtained as described above is wound around a pulley 44 having a guide groove 46.

Since the jaw portion 27 is in contact with the lower surface of the head 30, the profile 12A does not come off the guide 14A simply by lifting the profile 12A in the direction perpendicular to the surface of the belt body 2A. Further, the belt accessory 10A can be removed from the belt main body 2A by a procedure opposite to the procedure described above.

(Action and effect)
The belt accessory 10A according to the present embodiment can be attached to the belt main body 2A by sliding the profile 12A in the longitudinal direction x and engaging the engaging female portion 16 and the engaging male portion 18 with each other. Therefore, the belt accessory 10A can be easily attached to and detached from the belt main body 2A without using adhesion or fusion as in the prior art. When attaching the belt accessory 10A to the belt main body 2A, a special tool such as a heat press or an ultrasonic fusion machine is not required. Therefore, the belt accessory 10A can be easily attached to the belt main body 2A accordingly. Can do.

The belt 1A having a plurality of belt accessories 10A can be easily attached and detached. Therefore, if some of the belt accessories 10A are damaged, the damaged parts can be replaced by replacing them. Can be repaired easily. Since the belt accessory 10A can be easily removed, the belt 1A can clean the belt body 2A with the belt accessory 10A removed.

By detaching and observing the belt accessory 10A as appropriate, the life of the profile 12A can be determined. Since the belt accessory 10A can be attached to the belt main body 2A without adhesion or fusion, the material of the belt main body 2A, the profile 12A, and the guide 14A can be freely selected. Therefore, for example, a standard product formed of resin or rubber can be used as the belt main body 2A, and the profile 12A is made of a material suitable for contacting the conveyed product, and the guide 14A is made of a material suitable for contacting the guide groove 46. It can be.

The short side of the head 30 is arranged on the downstream side in the running direction of the belt body 2A, the opening 24 is arranged on the upstream side in the running direction, and the engaging male part 18 is engaged with the engaging female part 16. To do. The engaging male part 18 and the engaging female part 16 are more firmly engaged by the force pushing out the conveyed product. Further, the belt accessory 10A is attached to the belt main body 2A by sandwiching the belt main body 2A in the thickness direction z by the profile 12A and the guide 14A, and therefore the belt accessory 10A is not easily detached from the belt main body 2A.

Since the belt accessory 10A is fixed with the belt main body 2A sandwiched between the first belt contact surface 22 and the second belt contact surface 32, the belt accessory 10A is fixed to the belt main body 2A as compared with conventional bonding or fusion. The area is small. Therefore, the belt 1A is not easily affected by the diameter of the pulley to be wound, and can be applied to a pulley having a relatively small diameter as compared with a belt in which a conventional belt accessory is fixed to the belt body.

The belt 1 A is provided with the profile 12 A, so that the conveyed product can be more reliably sent out in the traveling direction. When the guide 14A enters the guide groove 46, the belt 1A is prevented from meandering while the belt body 2A is traveling and coming off the pulley 44. Therefore, the belt 1A can obtain high running stability and conveyance capability.

Since the head 30 is trapezoidal and the engaging male part 18 and the engaging female part 16 are integrated by contacting the regulating surface 26, the profile 12A is prevented from rotating with respect to the guide 14A. Can do. Even when a force is applied to the profile 12A from the conveyed product, the convex portion 36 is trapezoidal and is fitted in the through hole 42 of the belt main body 2A, so that it is possible to prevent the guide 14A from rotating with respect to the belt main body 2A. it can. Accordingly, the belt 1A can prevent the profile 12A from rotating with respect to the belt body 2A, and can hold the profile 12A in a predetermined posture with respect to the belt body 2A.

The belt 1A can more reliably prevent the profile 12A from rotating with respect to the belt body 2A by engaging the engagement protrusion 29 with the side surface of the belt body 2A.

The belt accessory 10A can be prevented from being displaced in the longitudinal direction x because the engaging male part 18 is attached to the through hole 42 penetrating in the thickness direction z.

(Modification)
In the case of the first embodiment, the case where the belt accessory 10A includes the profile 12A and the guide 14A has been described, but the present invention is not limited thereto. Hereinafter, modifications will be described with reference to the drawings with the same reference numerals for the same configurations as those of the first embodiment.

For example, a belt accessory 10B shown in FIG. 11 includes a profile 12A as a contour addition body provided on the conveyance surface 3, and a fixed body 50A provided on the pulley contact surface 5 and fixing the profile 12A to the belt body 2A. Is provided. The fixed body 50A has a locking part 52 instead of the guide part 31 in the first embodiment, and the locking part 52 and the engaging male part 18 are integrally formed. The locking portion 52 is a thin plate-like member to avoid interference with the pulley, and the engaging male portion 18 is integrally formed on the second belt contact surface 32 that is the upper surface. Since the belt 1B of this modification includes the belt accessory 10B, the same effects as those of the first embodiment can be obtained.

The belt accessory 10C shown in FIG. 12 includes a guide 14A as a contour addition body provided on the pulley contact surface 5 and a fixing body 54A provided on the transport surface 3 and fixing the guide 14A to the belt body 2A. . The fixed body 54A does not have the profile main body 20 in the first embodiment but has a female main body 21. The female main body 21 is provided with an engaging female portion 16 on the lower end in FIG. 12, that is, on the first belt contact surface 22 side in contact with the transport surface 3. Since the belt 1 C of the present modification includes the belt accessory 10 C, the same effect as in the first embodiment can be obtained.

In the case of the first embodiment, the belt accessory 10A has been described in which the profile 12A has the engaging female portion 16 and the guide 14A has the engaging male portion 18, but the present invention is not limited thereto. . For example, in the belt accessory 10 D shown in FIG. 13, the profile 12 B has a profile body 20 and an engaging male part 18. An engaging male portion 18 is provided on the first belt contact surface 22 of the profile body 20. The guide 14 B has a guide portion 31 and an engaging female portion 16. As for the guide part 31, the engaging female part 16 is provided in the 2nd belt contact surface 32 side which is an upper surface. The engaging female portion 16 has an opening 24 on the surface of the guide portion 31 that intersects the longitudinal direction x. At the upper end of the opening 24, a pair of jaws 27 protruding from the side surface of the opening 24 toward the center is provided. A guide surface 28 is provided at the tip of the jaw 27. Since the belt 1D of the present modification includes the belt accessory 10D, the same effect as in the first embodiment can be obtained.

The belt accessory 10E shown in FIG. 14 includes a guide 14B as a contour addition body provided on the pulley contact surface 5, and a fixed body 50A provided on the transport surface 3 and fixing the guide 14B to the belt body 2A. . The guide 14 B has a guide portion 31 and an engaging female portion 16.

Since the belt 1E provided with the belt accessory 10E shown in FIG. 14 is a thin plate-like member, the guide 14B can be fixed to the belt main body 2A without substantially protruding from the belt main body 2A. it can. Therefore, the belt 1E can be used as a driving belt as well as a conveying belt.

15 includes a belt accessory 10E and a belt body 2B. As shown in FIG. 16, the belt main body 2 B has a through hole 42 and a counterbore 43. The counterbore 43 is formed by processing the periphery of the through hole 42 of the transport surface 3 on which the fixed body 50A is disposed into a concave shape. The depth of the counterbore 43, that is, the length from the conveying surface 3 to the bottom surface of the counterbore 43 is the same as the thickness of the locking portion 52. Here, “same” is not limited to completely matching, but includes cases where they are slightly different.

In the fixed body 50A, the head 30 is passed through the through hole 42 from the conveying surface 3 side of the belt main body 2B, and the locking portion 52 is inserted into the counterbore 43. Subsequently, the guide 14 B is disposed on the pulley contact surface 5 with the opening 24 facing the head 30. By sliding the guide in the longitudinal direction x, the engaging male portion 18 and the engaging female portion 16 are engaged, and the guide 14B and the fixed body 50A are integrated (FIG. 15).

Since the depth of the counterbore 43 and the thickness of the locking part 52 are the same, there is no step between the surface of the locking part 52 and the conveying surface 3. That is, it can be said that the conveyance surface 3 of the belt 1F is flat. Therefore, the belt 1 F includes the guide 14 B on the pulley contact surface 5 and can hold the transport surface 3 flat. Therefore, the belt 1 F can prevent the belt accessory 10 E from restricting the transported object placed on the transport surface 3 or obstructing the transported object.

The belt main body 2B has been described with respect to the case where the conveying surface 3 has the counterbore 43, but the present invention is not limited thereto, and the pulley contact surface 5 may have a counterbore. In this case, the belt accessory 10B (FIG. 11) including the profile 12A as the contour addition body and the fixed body 50A can be applied. That is, by fitting the locking portion 52 of the fixed body 50 A into the counterbore formed on the pulley contact surface 5, the profile 12 A can be provided on the transport surface 3 and the pulley contact surface 5 can be held flat.

Although the case where the head is trapezoidal in plan view has been described, it may be a polygon such as a triangle or pentagon in plan view. That is, in a plan view, various shapes can be employed as long as they have an insertion surface that has a predetermined angle with respect to the longitudinal direction x and contacts the regulating surface.

The case where the opening 24 penetrates in the thickness direction of the profile from the front surface 33 toward the back surface 35 has been described, but the back surface 35 side may be closed. By blocking the back surface 35 side, foreign matter can be prevented from being mixed. When the back surface 35 side of the opening 24 is closed, the head of the engaging male part may be a rectangle having a side surface parallel to the longitudinal direction in plan view. In this case, the surface that closes the opening 24 on the side of the back surface 35 of the profile serves as a restriction surface, and the tip surface of the head contacts the restriction surface.

2. Second Embodiment A belt accessory according to a second embodiment will be described. In the case of the first embodiment, the belt accessory has been described with respect to the case where the combination of the engaging male part and the engaging female part is set as one set, and one set is provided in the width direction y, but the present invention is not limited thereto. Instead, two or more sets may be provided in the width direction y. When two sets of the engaging male part and the engaging female part are provided in the width direction y, the convex part may be omitted, or the shape of the head, the through hole, and the convex part in plan view may be a perfect circle. Good. In other words, the engaging male part may be rotatable with respect to the belt body in the rotation direction with the thickness direction of the belt body as the rotation axis. This will be described in detail with reference to the drawings. In addition, the same code | symbol is attached | subjected to the structure similar to the said 1st Embodiment, and description is abbreviate | omitted.

The belt accessory 10G shown in FIG. 17 includes a profile 12C and two guides 14C. Two sets of the engaging female portion 60 and the engaging male portion 62 are provided in the width direction y. The belt main body 2C shown in FIG. 17 has a longer width than the first embodiment. The width of the belt body 2C is longer than the profile 12C. The profile 12C is different from the first embodiment in that it has two engaging female portions 60 and does not have an engaging protrusion. The opening 63 (FIG. 21) of the engaging female portion 60 is not shown, but is closed on the back surface 35 side.

As shown in FIG. 18, the guide 14 C has a guide portion 31 and an engaging male portion 62. The engaging male part 62 has a head part 64 and a shaft part 34. The head 64 is a circular member in a plan view and is a cylindrical member. The head portion 64 is connected to the second belt contact surface 32 via the shaft portion 34. The second belt contact surface 32 is not provided with the convex portion in the first embodiment. That is, the lower end of the shaft portion 34 is connected to the second belt contact surface 32.

Next, a method of attaching the belt accessory 10G to the belt body 2C will be described. As shown in FIG. 19, first, a belt body 2 C is prepared in which a circular through hole 66 having the same planar shape as the head 64 is formed in the thickness direction z. Two through holes 66 are formed at a predetermined pitch in the longitudinal direction x and two in the width direction y. The belt main body 2 C has two rows in the width direction y, each row including a plurality of through holes 66 arranged in a row in the longitudinal direction x.

Next, as shown in FIG. 20, the guide 14 C is disposed on the pulley contact surface 5 side of the belt body 2 C, and the head 64 is passed through the through hole 66. Subsequently, as shown in FIG. 21, the profile 12 C is arranged on the transport surface 3 with the front surface 33 facing the head 64. By sliding the profile 12C in the longitudinal direction x, the engaging female portion 60 and the engaging male portion 62 are engaged, and the profile 12C and the guide 14C are integrated (FIG. 17).

The belt accessory 10G includes two sets of the engaging female portion 60 and the engaging male portion 62 in the width direction y, thereby preventing the rotation of the profile 12C with respect to the belt main body 2C, and the profile 12C with respect to the belt main body 2C. Can be held in a posture. Therefore, the guide 14C does not need to be fitted into the through hole 66 of the belt main body 2C, that is, does not need to be fixed in the rotation direction with the thickness direction z as the central axis. Compared with the first embodiment, the shape can be simplified.

The through-hole 66 formed in the belt main body 2C can be circular because the head 64 of the engaging male part 62 is circular in plan view. That is, since the shape of the through hole 66 is simple, the through hole 66 can be formed more easily than in the first embodiment.

3. Third Embodiment A belt accessory according to a third embodiment will be described. Components similar to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted. As shown in FIG. 22, the belt 1H includes a belt main body 2A and a belt accessory 10H.

The belt accessory 10H includes a guide 14D as a contour addition body and a fixed body 50A. As shown in FIG. 23, the guide 14D includes a guide portion 79A and an engaging female portion 83. The engaging female portion 83 includes a first opening 24 formed on the front surface 80 of the guide portion 79A that intersects the longitudinal direction x, a closing surface 86 that faces the first opening 24, and a side opposite to the first belt contact surface 22. And a second opening 85 formed in the surface 23 of the first. The range of the first opening 24 in the width direction y is partitioned by a pair of restriction surfaces 81. The pair of restricting surfaces 81 are inclined at a predetermined angle so that the distance in the width direction y between the pair of restricting surfaces 81 gradually decreases from the front surface 80 to the back surface 84 of the guide. The closing surface 86 is orthogonal to the longitudinal direction x.

Each protruding surface 82 as an engaging structure is formed on each regulating surface 81 one by one. The protrusions 82 protrude inward in the width direction y around the first opening 24 so as to be orthogonal to the longitudinal direction x from the respective restriction surfaces 81. An interval having a predetermined length YF is provided between the tips of the protrusions 82. The protrusions 82 are provided at the beginning of the respective regulating surfaces 81 on the front 80 side. The protrusion 82 has a receiving surface 87 on the back surface 84 side that is substantially orthogonal to the longitudinal direction x.

The engaging female portion 83 is provided with a jaw portion 27 so as to be in contact with the first belt contact surface 22, and a guide surface 28 is formed at the tip of the jaw portion 27. Since the guide portion 79A has the second opening 85, a portion corresponding to the engaging female portion 83 of the surface 23 is open to the outside.

The fixed body 50A has a locking part 52 and an engaging male part 18 as shown in FIG. The engaging male part 50A has the same configuration as the engaging male part shown in FIG. The engaging male part 18 has a head part 30, a shaft part 34, and a convex part 36. The head 30 has an inclined tapered portion 37 in which the distance between both side portions gradually decreases from the proximal end in the longitudinal direction x that is the long side toward the distal end in the longitudinal direction x that is the short side. The head 30 has a size and a shape that fit into the space (FIG. 23) of the engaging female portion 83 surrounded by the regulating surface 81 and the receiving surface 87. The length YM in the width direction y of the short side of the head 30 is shorter than the length YF of the interval between the tips of the protrusions 82. The base end surface 76 of the head 30 as an engagement surface is orthogonal to the longitudinal direction x.

The locking portion 52 is a thin plate-like member to avoid interference with the pulley, and the engaging male portion 18 is integrally formed on the second belt contact surface 32 that is the upper surface. In the fixed body 50A, the head portion 30 is passed through the through hole 42 from the conveying surface 3 side of the belt body 2A. Subsequently, the engaging male portion 18 is inserted into the engaging female portion 83A by sliding the guide 14D disposed on the pulley contact surface 5 with the front face 80 facing the head 30 in the longitudinal direction x.

The head 30 enters the opening 24 from the short side through the tip of the protruding portion 82, and the tapered portion 37 contacts the protruding portion 82. Further, the engaging male portion 18 moves relative to the engaging female portion 83 in the longitudinal direction x, so that the guide portion 79A extends in the direction in which the length YF between the tips of the protruding portions 82 increases, that is, outside the width direction y. Elastically deforms in the direction. When the guide portion 79A is elastically deformed outward in the width direction y, the head portion 30 passes between the tips of the protruding portions 82.

When the head 30 completely passes between the tips of the projecting portions 82, the guide portion 79A is elastically deformed, and the length YF between the tips of the projecting portions 82 that has spread returns to the original length. The head 30 is fitted into a space surrounded by the pair of regulating surfaces 81, the pair of receiving surfaces 87, and the closing surface 86. As described above, the engaging female portion 83A and the engaging male portion 18 are engaged, and the guide 14D and the fixed body 50A are integrated (FIG. 25).

Since the guide 14D has the second opening 85 on the surface 23 of the guide portion 79A, the workability when forming the engaging female portion 83 can be improved. That is, the regulating surface 81, the closing surface 86, the receiving surface 87, and the jaw portion 27 can be easily formed through the second opening 85. Therefore, the guide 14D can be easily manufactured. As shown in FIG. 25, the upper surface of the head 30 of the engaging male part 18 integrated with the engaging female part 83 can be visually recognized from the outside. Since the surface 23 of the guide portion 79A is open, that is, it is not necessary to cover the upper surface of the head 30, the height of the guide 14D protruding from the belt main body 2A can be reduced.

The head 30 fitted in the space surrounded by the regulating surface 81 and the receiving surface 87 is fixed in the longitudinal direction x when the base end surface 76 contacts the receiving surface 87. When the front surface 80 is viewed from the longitudinal direction x, the base end surface 76 of the head 30 is partially hidden by the protrusions 82 on both sides in the width direction y (FIG. 25). In this way, the guide 14D is firmly fixed by the fixed body 50A, so that the belt accessory 10H can be more reliably prevented from dropping off from the running belt 1H. Further, the guide 14D and the fixed body 50A can be separated by widening the space between the protrusions 82.

(Modification)
In the case of the present embodiment, the description has been given of the case where the projecting portion 82 projects from the regulating surface 81 inward in the width direction y and perpendicular to the longitudinal direction x with the opening 85 as the center.

In the case of this embodiment, although the case where the protrusion part 82 was provided in the engagement female part 83 was demonstrated, this invention is not limited to this. For example, the protruding portion may be provided on the side surface or the upper surface of the head of the engaging male portion. In this case, an effect similar to that of the present embodiment can be obtained by providing a recess on the inner surface of the opening corresponding to the protruding portion.

In the case of this embodiment, although the case where the protrusion part 82 was provided in the part of the beginning of the front surface 80 side of the control surface 81 was demonstrated, this invention is not limited to this. It is only necessary that at least one protrusion 82 be provided between the beginning portion on the front surface 80 side of the restriction surface 81 and the end portion, that is, the end portion on the back surface 84 side of the restriction surface 81.

26 is different from the guide 14D in FIG. 23 only in the outer shape of the guide portion 79B. The guide 14E has a columnar guide portion 79B. The guide portion 79 B has an engaging female portion 83, and one bottom surface (the lower surface in the case of FIG. 26) is the first belt contact surface 22. The engaging female portion 83 has a first opening 24 on the side surface of the guide portion 79B that intersects the longitudinal direction x. The side surface of the guide portion 79B in which the first opening 24 is formed is processed into a flat shape. The engaging female portion 83 has a second opening 85 opened to the outside on the other bottom surface 23 of the guide portion 79 B opposite to the first belt contact surface 22. Therefore, the guide 14 E can improve workability when forming the engaging female portion 83.

The guide part may have a polygonal column shape such as a triangle or a pentagon in plan view.

In the above embodiment, the case where the fixed body 50A has the engaging male portion 18 and the locking portion 52 has been described, but the present invention is not limited to this. As illustrated in FIG. 27, the fixed body 50 B may include the engaging male portion 18 and the profile main body 20.
