Description

  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 for conveying 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.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a belt accessory that can be easily attached to and detached from the belt main body without adhesion or fusion, and a belt provided with the belt accessory.

  As shown in FIG. 2, the profile body 20 has a rectangular shape that is long in the width direction of the belt body 2, and has a belt contact surface 22 that contacts the transport surface of the belt body 2 at the lower end in the drawing. An engaging female portion 16 is formed on the belt contact surface 22 side. The engaging female portion 16 is disposed at the center in the width direction of the belt contact surface 22 and has an opening 24 formed in the front surface of the profile main body 20. When the front surface of the profile body 20 is installed on the belt 1A, the front surface of the profile body 20 is disposed on the length direction side of the belt 1A. The opening 24 penetrates the profile body 20 in the thickness direction. Restricting surfaces 26 are formed on both sides of the opening 24. 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 is provided. A guide surface 28 is provided at the tip of the jaw 27.

  In the case of this figure, the engaging female portion 16 is provided in a female main body 21 formed integrally with the profile main body 20. 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. The profile 12 </ b> A may have an engagement protrusion 29 that engages with the side surface of the belt body 2. The engaging protrusions 29 are provided on both sides of the profile body 20 and protrude from the belt contact surface 22.

  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 to the back surface of the profile body 20. The guide surfaces 28 are parallel to each other with a constant distance between the tips of the jaw portions 27 from the front surface to the back surface of the profile body 20.

  As shown in FIG. 4, the guide 14 </ b> A has a guide main body 31, and the engaging male portion 18 is integrally formed with the guide main body 31. The guide main body 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 sectional shape. In the case of this figure, the longitudinal cross-sectional shape of the guide main body 31 is a trapezoid.

  The engaging male part 18 has a head part 30, a belt contact surface 32, a shaft part 34, and a convex part 36. The head 30 has a trapezoidal shape in plan view, and has an inclined insertion surface 38 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. The head portion 30 is connected to the belt contact surface 32 via a shaft portion 34. The belt contact surface 32 is the upper surface of the guide body 31 and contacts the pulley contact surface of the belt body 2.

Less than the thickness of

(installation method)
Next, a method for attaching the belt accessory 10A to the belt body 2 will be described. As shown in FIG. 6, first, a belt main body 2 is prepared in which a trapezoidal through hole 42 having the same shape as the planar shape of the head 30 is formed in the thickness direction. The through hole 42 is formed such that the short side and the long side are parallel to the width direction of the belt. Although omitted in this figure, a plurality of through holes 42 are formed at a predetermined pitch in the length direction of the belt body 2. In the case of this figure, there is one through hole 42 in the width direction of the belt body 2.

  Next, as shown in FIG. 7, the guide 14 </ b> A is disposed on the pulley contact surface side of the belt body 2, the head 30 is passed through the through hole 42, and the convex portion 36 is fitted into the through hole 42. Subsequently, as shown in FIG. 8, the profile 12 </ b> A is arranged on the transport surface with the front face facing the head 30. The opening 24 is disposed in the length direction of the belt body 2. By sliding the profile 12A in the length direction of the belt body 2, the head portion 30 is inserted into the opening 24 while the shaft portion 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 belt contact surface 22 of the profile 12A is in contact with the conveying surface, the belt contact surface 32 of the guide 14A is in contact with the pulley contact surface around the through hole 42, and the belt body 2 is sandwiched between the profile 12A and the guide 14A in the thickness direction. Thus, the belt accessory 10 </ b> A is attached to the belt body 2. The belt 1 </ b> A obtained as described above is wound around a pulley 44 having a guide groove 46.

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

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

  By detaching and appropriately observing the belt accessory 10A, the life of the profile 12A can be determined. Since the belt accessory 10A can be attached to the belt main body 2 without adhesion or fusion, the material of the belt main body 2, the profile 12A, and the guide 14A can be freely selected. Therefore, for example, a standard product made of resin or rubber can be used as the belt body 2, and the profile 12 </ b> A is made of a material suitable for contacting the conveyed product, and the guide 14 </ b> A 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 conveying direction of the belt body 2 and the opening 24 is arranged on the upstream side in the conveying 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 body 2 by sandwiching the belt body 2 in the thickness direction between the profile 12A and the guide 14A, and therefore the belt accessory 10A is not easily detached from the belt body 2.

  Since the belt accessory 10A is fixed with the belt main body 2 sandwiched between the belt contact surfaces 22 and 32, the area of the belt accessory 10A fixed to the belt main body 2 is smaller than that of conventional bonding or fusion. 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.

  By providing the profile 12 </ b> A, the belt 1 </ b> A can reliably feed the conveyed product in the conveying direction. When the guide 14A enters the guide groove 46, the belt 1A is prevented from meandering while the belt body 2 is running 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 force is applied to the profile 12A from the conveyed product, the convex portion 36 is trapezoidal and is fitted into the through hole 42 of the belt main body 2, thereby preventing the guide 14 </ b> A from rotating with respect to the belt main body 2. it can. Therefore, the belt 1 </ b> A can prevent the profile 12 </ b> A from rotating with respect to the belt body 2 and can hold the profile 12 </ b> A in a predetermined posture with respect to the belt body 2.

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

  In the belt accessory 10A, the engagement male part 18 is passed through the through hole 42 penetrating in the thickness direction of the belt main body 2 so as to prevent the belt main body 2 from being displaced in the length direction. be able to.

  In the case of the above 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, the belt accessory 10B shown in FIG. 11 includes a profile 12A as a contour addition body provided on the conveyance surface, and a fixing body 50 provided on the pulley contact surface and fixing the profile 12A to the belt body 2. . The fixed body 50 has a locking main body 52 instead of the guide main body 31 in the first embodiment. The locking body 52 is a thin plate-like member to avoid interference with the pulley. 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 10 </ b> C shown in FIG. 12 includes a guide 14 </ b> A as a contour addition body provided on the pulley contact surface, and a fixing body 54 provided on the transport surface and fixing the guide 14 </ b> A to the belt body 2. The fixed body 54 does not have the profile main body 20 in the first embodiment but has the female main body 21. Since the belt 1 </ b> C of the present modification includes the belt accessory 10 </ b> C, the same effect as in the first embodiment can be obtained.

  In the case of the above-described embodiment, the case where the profile 12A has the engaging female portion 16 and the guide 14A has the engaging male portion 18 has been described in the belt accessory 10A, but the present invention is not limited thereto. For example, in the belt accessory 10 </ b> D shown in FIG. 13, the profile 12 </ b> B has an engaging male part 56, and the guide 14 </ b> B has an engaging female part 58. Since the belt 1D of the present modification includes the belt accessory 10D, the same effect as in the first embodiment can be obtained.

  Although the case where the profile is a plate shape has been described, the present invention is not limited to this, and may be, for example, a trapezoidal shape, a mountain shape, or a semicircular shape in a side view.

  Although the case where the opening has penetrated in the thickness direction from the front to the back has been described, the back side may be closed. Since the back side is closed, foreign matter can be prevented from being mixed.

  Although the description has been given of the case where the restriction surface is in contact with the side surface of the head, the restriction surface includes a case in which the restriction surface is in contact with at least one of the side surface of the head, the top surface of the head, and the tip surface of the head.

  Although the case where the head is trapezoidal in plan view has been described, it may be a polygon such as a triangle or a pentagon in plan view.

  As for the accessory for the belt, the case where the combination of the engaging male part and the engaging female part is set as one set and the set is provided in the width direction of the belt main body has been described. Two or more sets may be provided in the direction. When two sets of the engaging male part and the engaging female part are provided in the width direction of the belt main body, the convex part may be omitted, and the shape of the head, the through hole, and the convex part in plan view is a perfect circle. It is good. 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 embodiment, and description is abbreviate | omitted.

  The belt accessory 10 </ b> E shown in FIG. 14 includes two sets of engaging female portions 60 and engaging male portions 62 in the width direction of the belt body 2. The belt body 2 shown in this figure has a longer width than the above embodiment. The width of the belt body 2 is longer than the profile 12C. The profile 12C is different from the above-described embodiment in that the profile 12C has two engaging female portions 60 and does not have an engaging protrusion. The opening 63 (FIG. 18) of the engaging female part 60 is not shown, but is closed on the back side.

  As shown in FIG. 15, the guide 14 </ b> C has a guide main body 31 and an engaging male part 62. The head 64 of the engaging male part 62 is circular in a plan view and is a cylindrical member. The head portion 64 is connected to the belt contact surface 32 via the shaft portion 34.

  Next, a method of attaching the belt accessory 10E to the belt body 2 will be described. As shown in FIG. 16, first, a belt body 2 is prepared in which a circular through hole 66 having the same planar shape as the head 64 is formed in the thickness direction. Two through holes 66 are formed in the width direction of the belt main body 2 and at a predetermined pitch in the length direction.

  Next, as shown in FIG. 17, the guide 14 </ b> C is disposed on the pulley contact surface side of the belt body 2, and the head 64 is passed through the through hole 66. Subsequently, as shown in FIG. 18, the profile 12 </ b> C is arranged on the transport surface with the front face directed to the head 64. By sliding the profile 12C in the length direction of the belt body 2, the engaging female portion 60 and the engaging male portion 62 are engaged, and the profile 12C and the guide 14C are integrated.

  The belt accessory 10E includes two sets of the engaging female portion 60 and the engaging male portion 62 in the width direction of the belt main body 2, thereby preventing the rotation of the profile 12C with respect to the belt main body 2, and the profile 12C with respect to the belt main body 2. Can be held in a predetermined posture. Therefore, since the guide 14C does not need to be fitted into the through hole 66 of the belt main body 2, the shape can be simplified as compared with the above-described embodiment because the convex portion can be omitted.

  Since the head 64 of the engagement male part 62 is circular in plan view, the through hole 66 formed in the belt body 2 can be circular. That is, since the shape of the through hole 66 is simple, the through hole 66 can be formed more easily than in the above embodiment.
