Description

Belt accessories and belts with belt accessories

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

Generally speaking, the conveying belt used in conveying devices for conveying paper sheets (such as printing paper), etc., uses a flat belt whose conveying surface is flat. The flat belt system is in surface contact with the conveyed object, so the conveyed object can be stably conveyed. However, there is a problem that the snake belt will move away from the pulley during walking. Here, it is known that there is a conveying belt with a guide provided with a guide for preventing meandering on the side (pulley contact surface) on the side that contacts the pulley of the belt (for example, Patent Document 1). In addition, there is known a conveyor belt provided with a contour member provided with a contour member such as a baffle on the transport surface (for example, Patent Document 2). The contour member is, for example, when transporting the transported object to a high place, to prevent the transported object from falling from the transport belt. The guides installed on the contact surface of the pulley or the contours installed on the conveying surface are generally joined to the belt by welding or welding.

In this patent specification, the running direction of the belt hanging on the pulley is called "longitudinal", and the direction perpendicular to the surface of the belt is called "thickness direction", and the direction perpendicular to the longitudinal direction and the above-mentioned thickness direction is (Axial) is called "width direction". Moreover, in this patent specification, "direction" is not limited to the case of one direction, but also includes the case of adding a direction opposite to the above one direction. Also, the surface in contact with the pulley of the belt hanging on the pulley is called the "inner peripheral surface" or "pulley contact surface", and the surface opposite to the surface in contact with the pulley is called the "outer peripheral surface" or "transport surface" ".

(Whole structure) Fig. 1 is a perspective view showing a belt 1A of this embodiment. In FIG. 1, the x direction is regarded as the longitudinal direction (also called the walking direction), the y direction is regarded as the width direction, and the z direction is regarded as the thickness direction. The belt 1A shown in FIG. 1 includes a belt body 2A and a belt attachment 10A. In FIG. 1, the belt body 2A is shown by an imaginary line for convenience of explanation. For the belt body 2A, an endless flat belt made of resin or rubber, a belt with teeth, or the like can be used. Although the belt attachment 10A is omitted in FIG. 1, a plurality of attachments are provided at a predetermined pitch in the longitudinal direction x.

The belt attachment 10A includes: a contour member 12A as an additional body of the contour member; and a guide 14A as a fixed body. The belt attachment 10A can be made of the same material as the belt body 2A or different materials. For example, the belt attachment 10A is made of synthetic resin such as polyacetal, nylon or polypropylene, or metal such as brass, iron, stainless steel or aluminum. The profile member 12A and the guide 14A can be made of the same material or different materials.

The profile 12A has a profile body 20 in a plate shape, and a female body 21 formed integrally with the profile body 20. The profile body 20 is a rectangle that is longer in the width direction y of the belt body 2A, and has a first belt contact surface 22 in contact with the conveying surface of the belt body 2A at the lower end in FIG. The profile 12A may have an engaging protrusion 29 that engages with the side 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 body 21 has a shape in which the thickness of the plate-shaped profile body 20 is locally thicker. The profile member 12A makes the thickness of the profile member body 20 other than the female body 21 thinner, whereby material reduction can be achieved.

As shown in FIG. 2, the female body 21 is arranged at the center of the profile body 20 in the width direction y, and is provided to be in contact with the first belt contact surface 22. The female body 21 is a contour member having a shape in which a triangular column is laid down. The female body 21 is provided with an engaging female part 16. The engaging female part 16 is formed on the first belt contact surface 22 side of the female body 21. The engaging female portion 16 may be formed by bending or cutting the contour body 20.

The engaging female portion 16 is arranged at the center of the first belt contact surface 22 in the width direction y, and has an opening 24 formed on the front surface 33 of the profile body 20. The front surface 33 of the profile body 20, when provided on the belt 1A, is arranged on the longitudinal x side of the belt 1A. That is, the front surface 33 of the profile body 20 crosses the longitudinal direction x of the belt body 2A. Therefore, the engaging female portion 16 is provided on the surface of the female body 21 crossing the longitudinal direction x of the belt body 2A and has an opening 24.

The opening 24 extends through the thickness direction of the profile body 20. That is, the opening 24 penetrates from the front surface 33 to the rear surface 35 of the profile body 20. On both sides of the opening 24, restriction surfaces 26 are formed. As shown in FIG. 3, the restricting surface 26 is a side surface of the opening 24, in which the distance from the front surface 33 to the rear surface 35 of the profile body 20 is inclined toward the direction in which the distance between the side surfaces decreases.

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

The introducer 14A has an engaging male part 18 and a guide part 31 (FIG. 1 ). The introducer 14A is engaged with the engaging male part 18 by the engaging female part 16 and integrated with the contour member 12A.

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

The male engagement portion 18 has a head portion 30, a shaft portion 34, and a convex portion 36. The upper end of the shaft portion 34 is connected to the lower surface of the head 30, and the lower end is connected to the upper surface of the convex portion 36. The head portion 30 is trapezoidal in plan view, and has a base end that is a long side and a tip that is a short side, and the distance between the two sides is gradually reduced and the inclined pushing portion 37 is inclined. The side surface of the head 30, that is, the surface of the pushing portion 37 is referred to as an insertion surface 38. The head 30 passes through the shaft portion 34 and is connected to the second belt contact surface 32.

As shown in FIG. 5, the shaft portion 34 has side surfaces that are parallel to each other at a certain distance from the base end of the head 30 to 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 is formed into a plate shape having the length in the thickness direction z as the thickness (also referred to as "height"). The convex portion 36 is in a shape other than a true circle in a plan view, and in the case of FIG. 5, it has the same trapezoidal shape as the top view of the head 30, in which it is arranged coaxially with the head 30 and the height is smaller than the belt The thickness of the body 2A.

(installation method) Next, a method of attaching the belt attachment 10A to the belt body 2A will be described. First, the belt body 2A shown in FIG. 6 is prepared. The belt body 2A has a conveying surface 3 as one side surface; a pulley contact surface 5 parallel to the other side surface of the conveying surface 3; and a through hole 42 penetrating from the conveying surface 3 to the pulley contact surface 5. That is, the belt body 2A having the trapezoidal through hole 42 having the same shape as the plan view of the head 30 is formed in the thickness direction z. The through hole 42 is formed so that the short side and the long side are parallel to the width direction y. Although it is omitted in FIG. 6, the through-hole 42 is formed in the longitudinal direction x and a plurality of holes are formed at a predetermined pitch. The plurality of through holes 42 are arranged in a row along the longitudinal direction x of the belt 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 14A is arranged on the pulley contact surface 5 side of the belt body 2A, passes through the head 30 to the through hole 42, and fits the convex portion 36 to the through hole 42. In a plan view, the convex portion 36 having a trapezoidal shape is inserted into the through hole 42 having the same trapezoidal shape. Therefore, the guide 14A is fixed to the belt body 2A with the thickness direction of the belt body 2A as a rotation axis turn around.

Next, as shown in FIG. 8, the front surface 33 is directed toward the head 30 to arrange the profile 12A to the conveying surface 3. The opening 24 is arranged on the surface of the female body 21 crossing the longitudinal direction x. By sliding the profile 12A in the longitudinal direction x, the 34 is in contact with the guide surface 28 while the head 30 is inserted into the opening 24 (FIG. 9 ). The insertion surface 38 of the head 30 inserted into the opening 24 comes into contact with the restriction surface 26, the male engagement portion 18 engages with the female engagement portion 16, and the contour member 12A and the introducer 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 contacts the conveying surface 3, and the second belt contact surface 32 of the guide 14A contacts the pulley contact surface 5 on the periphery of the through hole 42. The belt body 2A is sandwiched between the profile member 12A and the guide 14A in the thickness direction z, whereby the belt attachment 10A is attached to the belt body 2A. The belt 1A obtained as described above is wound around the pulley 44 including the guide groove 46.

With the jaw portion 27 contacting the lower surface of the head 30, the contour member 12A is only lifted in the vertical direction with respect to the surface of the belt body 2A, and the contour member 12A does not detach from the guide 14A. In addition, the belt attachment 10A can be detached from the belt body 2A in the reverse order to the above.

(Function and effect) The belt attachment 10A of this embodiment slides the profile member 12A in the longitudinal direction x to engage the engaging female portion 16 with the engaging male portion 18, whereby it can be attached to the belt body 2A. Therefore, the attachment 10A for the belt is not easily attached or welded as before, and can be easily attached to and detached from the belt body 2A. When attaching the belt attachment 10A to the belt body 2A, special tools such as a hot punch or an ultrasonic welding machine are not required, so the belt attachment 10A can be easily installed to the belt body 2A.

The belt 1A including a plurality of belt attachments 10A can be easier to install and remove the belt attachment 10A. Therefore, when a part of the belt attachment 10A is damaged, it is easier to repair by replacing the damaged part. The belt attachment 10A can be easily removed, so the belt 1A can wash the belt body 2A with the belt attachment 10A removed.

By suitable removal to observe the belt attachment 10A, the life of the profile member 12A can be judged. The accessory 10A for the belt can be attached to the belt body 2A without adhesion or welding, so the materials of the belt body 2A, the contour member 12A and the guide 14A can be freely selected. Therefore, for the belt body 2A, a standard product formed of, for example, resin or rubber can be used. At the same time, the contour member 12A can be made of a material suitable for contact with the conveyed object, and the guide 14A can be made of a material suitable for contact with the guide groove 46. .

The short side of the head 30 is arranged to the downstream side of the belt body 2A in the walking direction, and the opening 24 is arranged to be an upstream side in the walking direction to engage the male portion 18 to the female portion 16. The male engaging portion 18 and the female engaging portion 16 are able to engage with each other more firmly by the force of pushing out the carried objects. Moreover, the belt body 2A is sandwiched between the profile member 12A and the guide 14A in the thickness direction z, whereby the belt attachment 10A is attached to the belt body 2A, so the belt attachment 10A is less likely to come off the belt body 2A .

The belt attachment 10A clamps and fixes the belt body 2A by the first belt contact surface 22 and the second belt contact surface 32, so compared with the previous adhesion or fusion, the area fixed to the belt body 2A is small. Therefore, the belt 1A is less likely to be affected by the diameter of the wound pulley. Compared with the belt where the previous belt accessory is fixed to the belt body, it can also be applied to a pulley with a smaller diameter.

The belt 1A includes a profile member 12A, so that the conveyed object can be more surely conveyed in the walking direction. The belt 1A enters the guide groove 46 by the guide 14A to prevent the belt body 2A from snaking during walking to detach from the pulley 44. Therefore, the belt 1A can obtain higher walking stability and carrying capacity.

The head portion 30 is trapezoidal, and the engaging male portion 18 and the engaging female portion 16 are integrated by contacting with the restricting surface 26, so that the profile member 12A can be prevented from rotating relative to the guide 14A . Even when force is applied to the profile member 12A from the conveyed object, the convex portion 36 is trapezoidal, in which it is fitted into the through hole 42 of the belt body 2A, so that the guide 14A can be prevented from rotating relative to the belt body 2A. Therefore, the belt 1A can prevent the profile member 12A from rotating relative to the belt body 2A, and the profile member 12A can maintain the predetermined posture relative to the belt body 2A.

The belt 1A is engaged with the side surface of the belt body 2A by the engaging protrusion 29, which can more surely prevent the profile member 12A from rotating relative to the belt body 2A.

The attachment 10A for the belt is fitted with the engaging male portion 18 through the through-hole 42 penetrating in the thickness direction z, so that the occurrence of deviation in the longitudinal direction x can be prevented.

(Modification) In the case of the above-described first embodiment, the accessory 10A for a belt is described as including the profile 12A and the guide 14A, but the present invention is not limited to this. In the following, the modified example will be described with reference to the same structures as those in the first embodiment described above and the same reference numerals.

For example, the belt attachment 10B shown in FIG. 11 includes: a profile member 12A as a profile member attachment body provided on the conveying surface 3; and a fixed body 50A, which is provided on the pulley contact surface 5 and fixes the profile member 12A to the belt Body 2A. The fixing body 50A replaces the guide portion 31 in the first embodiment described above, and has a locking portion 52 which is formed integrally with the engaging male portion 18. In order to avoid interference with the pulley, the locking portion 52 is a thin plate-shaped member, and the engaging male portion 18 is integrally formed on the second belt contact surface 32 as the upper surface. The belt 1B of this modification includes the belt attachment 10B, so the same effect as the first embodiment described above can be obtained.

The belt attachment 10C shown in FIG. 12 includes: a guide 14A as an additional body of the profile member provided on the pulley contact surface 5; and a fixed body 54A provided on the conveying surface 3 to fix the guide 14A to Belt body 2A. The fixed body 54A does not have the profile body 20 in the first embodiment described above, but has a female body 21. The female body 21 is attached to the lower end of FIG. 12, that is, on the side of the first belt contact surface 22 that contacts the conveying surface 3, and an engaging female portion 16 is provided. The belt 1C of this modification includes the belt attachment 10C, so the same effect as the first embodiment described above can be obtained.

In the case of the first embodiment described above, although the case where the belt attachment 10A, the profile 12A has the engaging female part 16 and the guide 14A has the engaging male part 18 has been described, the present invention is not limited to this . For example, the accessory 10D for a belt shown in FIG. 13, the profile member 12B has a profile body 20 and an engaging male portion 18. On the first belt contact surface 22 of the profile body 20, an engaging male portion 18 is provided. The introducer 14B has a guide portion 31 and an engaging female portion 16. The guide portion 31 is provided on the second belt contact surface 32 side as the upper surface, and is provided with an engaging female portion 16. The engaging female part 16 is provided on the surface of the guide part 31 crossing the longitudinal direction x, and has an opening 24. At the upper end of the opening 24, a pair of jaws 27 protruding from the side of the opening 24 toward the center are provided. At the tip of the jaw 27, a guide surface 28 is provided. The belt 1D of this modification includes the belt attachment 10D, so the same effects as the first embodiment described above can be obtained.

The belt attachment 10E shown in FIG. 14 includes: a guide 14B as an additional body of the profile member provided on the contact surface 5 of the pulley; and a fixed body 50A, which is provided on the conveying surface 3 and fixes the guide 14B to Belt body 2A. The introducer 14B has a guide portion 31 and an engaging female portion 16.

The belt 1E including the belt attachment 10E shown in FIG. 14 has the fastening portion 52 as a thin plate-shaped member, so that the guide 14B can be fixed to the belt body 2A almost without protruding from the belt body 2A. Therefore, the belt 1E is used in addition to the conveyor belt and can also be used as a driving belt.

The belt 1F shown in FIG. 15 includes a belt attachment 10E and a belt body 2B. As shown in FIG. 16, the belt body 2B has a through hole 42 and a countersunk hole 43. The countersunk hole 43 is formed by processing the periphery of the through hole 42 of the conveying surface 3 on which the fixing body 50A is arranged into a concave shape. The depth of the countersunk hole 43, that is, the length from the conveying surface 3 to the bottom surface of the countersunk hole 43, is the same as the thickness of the locking portion 52. Here, the so-called "same" is not limited to completely identical situations, it includes several different situations.

The fixed body 50A is a head portion 30 that is inserted into the counterbore 43 from the conveyance surface 3 side of the belt body 2B through the through hole 42 and the locking portion 52. Next, the opening 24 is directed toward the head 30 to arrange the guide 14B to the pulley contact surface 5. By sliding the introducer in the longitudinal direction x, the engaging male part 18 and the engaging female part 16 are engaged, and the introducer 14B and the fixed body 50A are integrated (FIG. 15 ).

The depth of the countersunk hole 43 is the same as the thickness of the locking portion 52, so there is no drop between the surface of the locking portion 52 and the conveying surface 3. That is, the conveying surface 3 of the belt 1F can be said to be flat. Therefore, the belt 1F includes the guide 14B on the pulley contact surface 5 while keeping the conveying surface 3 flat. Therefore, the belt 1F can prevent the accessory 10E for the belt from restricting the conveyed object placed on the conveying surface 3 or becoming an obstacle to the conveyed object.

The belt body 2B has been described as having a countersunk hole 43 in the conveying surface 3, however, the present invention is not limited to this, and the countersunk surface 5 may have a countersunk hole. In this case, it can be applied to the belt attachment 10B including the profile member 12A as the profile member attachment body and the fixed body 50A (FIG. 11 ). That is, the locking portion 52 of the fixed body 50A is fitted into the countersunk hole formed in the pulley contact surface 5, whereby the conveying surface 3 includes the profile 12A, and at the same time, the pulley contact surface 5 can be kept flat.

The head has been described as being trapezoidal in plan view, but may be polygonal such as triangle, pentagon, etc. in plan view. That is, if it has a predetermined angle with respect to the longitudinal direction x in a plan view and has an insertion surface that contacts the restriction surface, various shapes can be adopted.

The opening 24 has been described from the front surface 33 to the rear surface 35 and penetrates the thickness direction of the profile. However, the rear surface 35 side may be closed. If the rear surface 35 side is occluded, foreign matters can be prevented from being mixed. When the rear surface 35 side of the opening 24 is occluded, the head portion of the male engagement portion may be a rectangle having side surfaces parallel to the longitudinal direction in a plan view. In this case, the surface where the opening 24 is closed on the rear surface 35 side of the profile member becomes the restriction surface, and the tip surface of the head contacts the restriction surface.

2. Second embodiment The accessory for the belt of the second embodiment will be described. In the case of the above-mentioned first embodiment, although it has been described that the accessory for a belt is a combination of the engaging male part and the engaging female part, and a group is provided in the width direction y, the present invention is not limited to Here, two or more sets in the width direction y may be provided. In addition, when the engaging male part and the engaging female part are provided in two groups 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 a plan view may be a true circle. That is, the engaging male portion may be rotated relative to the belt body in the rotation direction in which the thickness direction of the belt body is regarded as the rotation shaft. Refer to the picture to explain in detail. In addition, the same structure as that of the above-mentioned first embodiment is given the same number, and its description is omitted.

The accessory 10G for a belt shown in FIG. 17 includes a profile member 12C and two guides 14C. The engaging female part 60 and the engaging male part 62 are provided with two groups in the width direction y. The belt main body 2C shown in FIG. 17 has a longer lateral length than the first embodiment described above. The lateral length of the belt body 2C is longer than that of the profile member 12C. The contour member 12C is different from the first embodiment described above in that it has two points for engaging the female part 60 and points that do not have engaging protrusions. Although the opening 63 (FIG. 21) of the engaging female part 60 is not shown, the rear surface 35 side is closed.

As shown in FIG. 18, the guide 14C has a guide portion 31 and an engaging male portion 62. The engaging male part 62 has a head 64 and a shaft 34. The head 64 is circular in plan view, and it is a cylindrical member. The head 64 passes through the shaft portion 34 and is connected to the second belt contact surface 32. The second belt contact surface 32 is not provided with the convex portion in the first embodiment described above. 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 attachment 10G to the belt body 2C will be described. As shown in FIG. 19, first, a belt body 2C formed with a circular through-hole 66 having the same planar shape as the head 64 in the thickness direction z is prepared. Two through holes 66 are formed in the width direction y, and a plurality of through holes are formed at a predetermined pitch in the longitudinal direction x. The belt body 2C is a row formed by plural through holes 66 arranged in one row in the longitudinal direction x, and has two rows in the width direction y.

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

The belt attachment 10G is in the width direction y, and includes two sets of engaging female parts 60 and engaging male parts 62, thereby preventing the profile member 12C from rotating relative to the belt body 2C, and relative to the belt body 2C, The profile 12C is maintained in a predetermined posture. Therefore, the guide 14C does not need to be fitted into the through hole 66 of the belt body 2C, that is, it does not need to be fixed in the rotation direction in which the thickness direction z is taken as the central axis, so the convex portion can be omitted. Compared with the first embodiment described above, the shape can be simplified.

The head portion 64 of the engaging male portion 62 is circular in plan view, whereby the through hole 66 formed in the belt body 2C can be circular. That is, the shape of the through-hole 66 is very simple, and as a result, the through-hole 66 can be formed more simply than the first embodiment described above.

3. Third embodiment The accessory for the belt of the third embodiment will be described. The same structure as that of the first embodiment is given the same number, and its description is omitted. As shown in FIG. 22, the belt 1H includes a belt body 2A and a belt attachment 10H.

The belt attachment 10H includes a guide 14D as a profile attachment body and a fixed body 50A. As shown in FIG. 23, the introducer 14D has a guide portion 79A and an engaging female portion 83. The engaging female portion 83 has: a first opening 24 formed on the front surface 80 of the guide portion 79A crossing the longitudinal direction x; an occlusion surface 86 facing the first opening 24; and a second opening 85 formed on the The surface 23 on the opposite side of the first belt contact surface 22. The first opening 24 is a range in the width direction y and is divided by a pair of restriction surfaces 81. The pair of restricting surfaces 81 are from the front surface 80 to the rear surface 84 of the introducer, and the distance between the pair of restricting surfaces 81 in the width direction y decreases gradually and is inclined at a predetermined angle. The occlusion surface 86 is perpendicular to the longitudinal direction x.

Each restricting surface 81 is formed with a protrusion 82 as an engaging structure. The protruding portion 82 is centered on the first opening 24 and protrudes perpendicularly to the longitudinal direction x from each restricting surface 81 in the inner direction of the width direction y. Between the tips of the protrusions 82, there is a space having a predetermined length YF. The protruding portion 82 is provided at the beginning of the front surface 80 side of each restricting surface 81. The protruding portion 82 is on the rear surface 84 side, and has a receiving surface 87 that is substantially perpendicular 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. The guide portion 79A has the second opening 85, whereby the portion corresponding to the engaging female portion 83 of the surface 23 is opened to the outside.

As shown in FIG. 24, the fixed body 50A has a locking portion 52 and an engaging male portion 18. The engaging male portion 50A has the same structure as the engaging male portion shown in FIG. 11. The male engagement portion 18 has a head portion 30, a shaft portion 34, and a convex portion 36. The head 30 has a base end which is a longitudinal x of the long side and a tip which is the longitudinal x of the short side, and the distance between the two sides is gradually decreased and the pushing portion 37 is inclined. The head 30 has a size and shape to fit into the space (FIG. 23) of the female part 83 enclosed by the restricting 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 the engaging surface is perpendicular to the longitudinal direction x.

The locking portion 52 is a thin plate-shaped member to avoid interference with the pulley. On the second belt contact surface 32 as the upper surface, the engaging male portion 18 is integrally formed. The fixed body 50A is a head 30 passing through the through hole 42 from the conveyance surface 3 side of the belt body 2A. Next, the front surface 80 is directed toward the head 30 so that the guide 14D arranged to the pulley contact surface 5 slides in the longitudinal direction x, thereby inserting the engaging male portion 18 to the engaging female portion 83A.

The head 30 passes between the tips of the protrusions 82 from the short side to enter the opening 24, and the pushing portion 37 contacts the protrusions 82. Moreover, the engaging male portion 18 is relatively moved in the longitudinal direction x relative to the engaging female portion 83, whereby the guide portion 79A is a direction in which the length YF between the tips of the protruding portions 82 increases, that is, Elastically deforms outward in the width direction y. The guide portion 79A is elastically deformed outward in the width direction y, and the head 30 passes between the tips of the protrusions 82.

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

The guide 14D has the second opening 85 on the surface 23 of the guide portion 79A. Therefore, when the engaging female portion 83 is formed, workability can be improved. That is, through the second opening 85, the restriction surface 81, the blocking surface 86, the receiving surface 87, and the jaw 27 can be formed relatively easily. Therefore, the guide 14D can be manufactured relatively easily. As shown in FIG. 25, the upper surface of the head 30 of the male engaging portion 18 integrated with the female engaging portion 83 can be recognized from the outside. Since the surface 23 of the guide portion 79A is opened, that is, there is no need to cover the upper surface of the head 30, so the height of the guide 14D protruding from the belt body 2A can also be reduced.

The head 30 embedded in the space surrounded by the restricting surface 81 and the receiving surface 87 has the base end surface 76 contact the receiving surface 87, whereby it is fixed in the longitudinal direction x. When the front surface 80 is viewed from the longitudinal direction x, the base end surface 76 of the head 30 is hidden by the protrusion 82, and both sides of the width direction y are concealed (FIG. 25). In this way, the guide 14D is strongly fixed by the fixing body 50A, so that it is possible to more surely prevent the accessory 10H for the belt from falling off from the belt 1H during running. Moreover, by expanding the space between the protruding portions 82, the guide 14D and the fixed body 50A can be separated.

(Modification) In the case of the present embodiment, although it has been described that the protruding portion 82 takes the opening 85 as the center, and protrudes perpendicularly to the longitudinal direction x from the restricting surface 81 inward in the width direction y, the present invention is not limited to Here. For example, the protruding portion may protrude in a direction slightly offset from the longitudinal direction x in the widthwise direction y.

In the case of the present embodiment, although the case where the protruding portion 82 is provided on the engaging female portion 83 has been described, the present invention is not limited to this. For example, the protruding portion may be provided on the side surface or upper surface of the head of the engaging male portion. In this case, by providing the concave portion to the inner surface corresponding to the opening of the aforementioned protruding portion, the same effect as the present embodiment can be obtained.

In the case of the present embodiment, although it has been described that the protruding portion 82 is provided at the beginning of the front surface 80 side of the restricting surface 81, the present invention is not limited to this. The protruding portion 82 only needs to be provided at least one from the start portion on the front surface 80 side of the restriction surface 81 to the end portion, that is, to the end portion on the rear surface 84 side of the restriction surface 81.

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

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

In the case of the above-mentioned 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 shown in FIG. 27, the fixed body 50B may have the engaging male portion 18 and the profile body 20. The belt 1J shown in FIG. 27 includes the belt attachment 10J having the guide 14D and the profile body 20, whereby the same effect as the first embodiment described above can be obtained. In FIG. 27, although the structure having the engaging male portion 18 and the profile body 20 is referred to as the fixed body 50B, the fixed body 50B is the same as the profile 12B shown in FIG. 13, so it can also be referred to as Contour piece attached body. In this case, the introducer 14D is called a fixed body.

4. Modification The present invention is not limited to the above-mentioned embodiment, and can be modified as appropriate within the scope of the present invention.

The profile body 20 has been described in the form of a plate. However, the present invention is not limited to this. For example, it may be trapezoidal, mountain-shaped, semicircular, etc. in a side view.

The restriction surface has been described as being in contact with the side of the head, but it includes a situation where it is in contact with at least one of the side of the head, the ceiling surface of the head, and the tip surface of the head.

The above-mentioned first embodiment, the above-mentioned second embodiment and the above-mentioned third embodiment may be combined as appropriate and applied. Although specific examples are illustrated below, the present invention is not limited to this.

For example, in the second embodiment, the case where the engaging male portion 62 has the cylindrical head 64 has been described. However, the present invention is not limited to this, and the engaging male portion 18 of the first embodiment can also be applied.

Furthermore, the second embodiment can also be applied to the belt attachments 10B and 10D shown in FIG. 11 or FIG. 13 of the first embodiment. In this case, the engaging protrusions 29 of the profile pieces 12A, 12B can be omitted.

Modifications from the third embodiment to the first embodiment or the second embodiment can also be applied.

Moreover, in the case of the guides 14D and 14E shown in FIGS. 23 and 26, although the case where the engaging female portion 83 has the protruding portion 82 has been described, the present invention is not limited to this, and it can also be applied to The guides 14B and 14C that do not have the protrusion 82 shown in the first embodiment and the second embodiment.
