Description

[Technical Field]

[0001] The present invention relates to a profiled belt comprising a belt body and a profile attached to the back surface of the belt body. [Background technology]

[0002] A profiled belt 900 as shown in FIGS. 19 and 20 is known, which includes a belt body 910 and a profile 920 attached to a back surface 910a of the belt body 910 (see Patent Document 1).

[0003] Specifically, this profiled belt 900 includes a belt body 910, a profile 920, and a fixing member 930 for detachably fixing the profile 920 to the belt body 910.

[0004] The belt body 910 has a protrusion 911 protruding from a back surface 910a, and this protrusion 911 extends from one end 910b to the other end 910c of the belt body 910 in the belt width direction.

[0005] The profile 920 has a recess 921 in a bottom surface (surface opposite to the rear surface 910a) 920a, into which the protrusion 911 is fitted.

[0006] The profile 920 and the protrusion 911 are each formed with a through hole 922, 912 through which the fixing member 930 is inserted, and the through holes 922, 912 penetrate the belt width direction through the center of the belt longitudinal direction of the profile 920 and the protrusion 911, respectively.

[0007] The fixing member 930 extends in the belt width direction and is inserted into the through holes 922 and 912 of the profile 920 and the protrusion 911 . [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-216259 Summary of the Invention [Problem to be solved by the invention]

[0009] In the profiled belt 900 described above, the profile 920 can be replaced with one having various shapes, but since the profile 920 is not in contact with the belt main body 910 (rear face 910a) on both sides of the protrusion 911 in the belt width direction, the profile 920 is prone to vibrating in the belt width direction when the belt is driven, etc. In particular, in the curved portion (portion wound around pulleys 951 and 952) when the profiled belt 900 is arranged in an endless manner as shown in Fig. 21, the entire bottom face 920a of the profile 920 is separated from the belt main body 910 (rear face 910a), so the profile 920 is more likely to vibrate in the width direction.

[0010] Therefore, an object of the present invention is to provide a profiled belt that can suppress vibration of the belt body in the width direction at the profile. [Means for solving the problem]

[0011] The profiled belt of the present invention comprises: The belt body, a profile removably attached to the back surface of the belt body; a fixing member that fixes the profile to the belt body, The belt body has a protrusion protruding from the back surface, In the width direction of the belt body, the dimension of the convex portion is smaller than the dimension of the belt body, The profile may include: a first portion adjacent to the protruding portion in a protruding direction of the protruding portion; a pair of second portions extending from the first portion toward the back surface of the belt body to a position where the second portions abut on the back surface of the belt body on both sides of the convex portion in the width direction of the belt body, The fixing member extends in the width direction and is inserted into each of the pair of second portions with the protrusions inserted therethrough.

[0012] According to this configuration, a pair of second portions of the profile abut against the belt body (back surface) on both sides of the convex portion in the width direction of the belt body, thereby suitably suppressing the widthwise vibration of the profile when the profiled belt is driven, etc.

[0013] In addition, in the profiled belt, The protrusion and each second portion have a hole extending in the width direction and through which the fixing member is inserted, The profile may have a pair of guide portions extending from the first portion along the convex portion toward the back surface of the belt body on both sides of the convex portion in the longitudinal direction of the belt body.

[0014] According to this configuration, when the profile is placed on the back surface of the belt body so that the convex portion fits between the pair of second portions, the pair of guide portions align the profile with the convex portion in the longitudinal direction of the belt body (i.e., align the convex portion with each hole of the pair of second portions in the longitudinal direction), thereby making it easier to insert or fasten the fixing member into each hole.

[0015] In addition, in the profiled belt, The profile may have a support portion extending from a position in the first portion spaced apart from the second portion in the longitudinal direction of the belt body toward the back surface of the belt body to a position abutting the back surface of the belt body.

[0016] With this configuration, the profile can be prevented from vibrating in the longitudinal direction.

[0017] In addition, in the profiled belt, the protrusion and one of the pair of second portions have an insertion hole penetrating in the width direction, the other second portion of the pair of second portions has a screw hole extending in a direction from the one second portion toward the other second portion in the width direction and having a female thread on an inner circumferential surface, The fixing member may be constituted by a bolt extending in the width direction and having a male thread at its tip, and may be inserted into the protrusion and each insertion hole of the one second portion, and may be screwed into a threaded hole of the other second portion.

[0018] According to this configuration, the profile can be fixed to and removed from the belt body by inserting and removing the bolt serving as the fixing member. [Effects of the Invention]

[0019] As described above, according to the present invention, it is possible to provide a profiled belt in which vibration of the belt body in the width direction at the profile is suppressed. [Brief explanation of the drawings]

[0021] Hereinafter, one embodiment of the present invention will be described with reference to FIGS.

[0022] As shown in Figures 1 to 5, the profiled belt 1 according to this embodiment comprises an endless (annular) belt body 2, at least one profile 3 removably attached to the outer surface (back surface) 21a of the belt body 2, and a fixing member 4 that fixes the profile 3 to the belt body 2.

[0023] In this profiled belt 1, the profiles 3 are removably attached, so they can be easily replaced (exchanged) if damaged or soiled. In addition, the profiles 3 can be replaced with profiles of appropriate material and shape depending on the material, physical properties, shape, etc. of the goods being transported by the profiled belt 1.

[0024] The profiled belt 1 of this embodiment has a plurality of profiles 3, which are arranged on the outer surface 21a of the belt body 2 at intervals in the longitudinal direction of the belt body 2 (hereinafter referred to as the "belt longitudinal direction") The profiled belt 1 is wound around, for example, a drive pulley P1 and a driven pulley P2, and runs in accordance with the rotation of the pulleys P1 and P2.

[0025] Specifically, the belt body 2 has a belt-shaped belt base 21 having a plurality of teeth 211 arranged in the belt longitudinal direction on its inner surface (the surface opposite to the outer surface 21a) 21b, and at least one protrusion 22 protruding from the outer surface 21a of the belt base 21. The belt body 2 of this embodiment has a plurality of protrusions 22, which are arranged at intervals in the belt longitudinal direction. More specifically, the plurality of protrusions 22 are arranged at equal intervals in the belt longitudinal direction on the outer surface 21a of the belt base 21. The intervals between the protrusions 22 are set based on the object to be conveyed by the profiled belt 1.

[0026] In the belt main body 2 of this embodiment, the belt base 21 and the protrusions 22 are made of separate members. By making the belt base 21 and the protrusions 22 out of separate members in this way, the protrusions 22 can be made of a different material from that of the belt base 21. For example, the belt base 21 is made of urethane or the like, and the protrusions 22 are made of a thermoplastic elastomer or the like. These multiple protrusions 22 are fused to the outer surface 21a of the belt base 21.

[0027] Each protrusion 22 protrudes from the outer surface 21a of the belt base 21 and extends in the width direction of the belt main body 2 (hereinafter referred to as the "belt width direction"). In this embodiment, the protrusion 22 is a cylindrical portion extending in the belt width direction. That is, the protrusion 22 has a through hole (insertion hole) 221 that penetrates in the belt width direction. In this embodiment, the through hole 221 is a through hole that extends in the belt width direction and has the same cross-sectional shape at each position in the belt width direction.

[0028] The dimension of the protrusions 22 in the belt width direction is smaller than the dimension of the belt base 21 in the belt width direction. In the belt body 2 of this embodiment, the protrusions 22 are arranged in the center of the belt base 21 (outer surface 21a) in the belt width direction. At this time, a predetermined distance α is formed between each edge of the protrusions 22 in the belt width direction and the edge of the belt base 21 corresponding to the end (see FIG. 3).

[0029] 6, the profile 3 has a first portion 31 adjacent to the protrusion 22 in the protruding direction of the protrusion 22 (in other words, in the normal direction to the outer surface 21a), and a pair of second portions 32 on both sides of the protrusion 22 in the belt width direction, extending from the first portion 31 toward the outer surface 21a of the belt base 21 to a position where the second portions 32 abut against the outer surface 21a. The profile 3 also has a pair of guide portions 33 on both sides of the protrusion 22 in the belt longitudinal direction, extending from the first portion 31 along the protrusion 22 toward the outer surface 21a of the belt base 21. The profile 3 also has a support portion 34 extending from a position in the first portion 31 spaced apart from the second portion 32 in the belt longitudinal direction toward the outer surface 21a of the belt base 21 to a position where the second portions 32 abut against the outer surface 21a of the belt base 21. The profile 3 of this embodiment has a pair of support portions 34 extending from a position spaced apart on one side of the belt longitudinal direction from the second portion 32 and a position spaced apart on the other side of the belt longitudinal direction from the second portion 32. In the profile 3 of this embodiment, the first portion 31 forms a storage portion capable of storing an object, and each second portion 32 forms an engagement portion that engages with the protrusion 22 of the belt body 2.

[0030] The storage section (first section) 31 extends in the belt longitudinal direction and the belt width direction at a position adjacent to the protrusion 22 in the protrusion direction of the protrusion 22. In other words, the storage section 31 extends along the outer surface 21a of the belt base 21 in a straight state. Specifically, the storage section 31 has a bottom wall 311 extending in the belt longitudinal direction and the belt width direction, and a cylindrical peripheral wall 312 extending from the periphery of the bottom wall 311 in the protrusion direction of the protrusion 22. In the storage section 31 of this embodiment, the bottom wall 311 is rectangular when viewed from the protrusion direction, and the peripheral wall 312 is rectangular cylindrical. That is, the storage section 31 is a bottomed rectangular cylindrical shape. The dimension of the storage section 31 in the belt width direction is smaller than the dimension of the belt base 21 in the width direction.

[0031] Each of the pair of engagement portions (second portions) 32 extends from the bottom wall portion 311 of the storage portion 31 toward the outer surface 21a at a position adjacent to the protrusion 22 in the belt width direction, and has an abutment surface 321 at its tip (the end portion on the outer surface 21a side) that can come into surface contact with the outer surface 21a. The engagement portion 32 in this embodiment has a quadrangular prism shape, and the abutment surface 321 is rectangular. Furthermore, each engagement portion 32 extends from the center of the bottom wall portion 311 in the belt longitudinal direction toward the outer surface 21a.

[0032] Each engaging portion 32 has a through-hole (hole) 322 that extends in the belt width direction and into which the fixing member 4 is inserted. The through-hole 322 of this engaging portion 32 is arranged at a position that overlaps with the through-hole 221 of the protruding portion 22 when viewed in the belt width direction.

[0033] In the profile 3 of this embodiment, the through-hole (insertion hole) 322A of one engaging portion 32A of the pair of engaging portions 32 is a through-hole that extends in the belt width direction and has a shape that follows the shape of the fixing member 4 (in the example of this embodiment, the head portion of the bolt). Furthermore, the through-hole (screw hole) 322B of the other engaging portion 32B of the pair of engaging portions 32 has a female thread 322M formed on the inner circumferential surface (see FIG. 3).

[0034] Each of the pair of guide portions 33 extends from the bottom wall portion 311 toward the outer surface 21a of the belt base 21 at a position adjacent to (along) the protrusion 22 on both sides of the protrusion 22 in the belt longitudinal direction, and also extends in the belt width direction. The interval between the pair of guide portions 33 in the belt longitudinal direction corresponds to the dimension of the protrusion 22 in the belt longitudinal direction (more specifically, the interval at which the protrusion 22 fits) (see FIG. 5). The interval between the pair of guide portions 33 in this embodiment is such that when the profile 3 is placed at the position of the protrusion 22 on the outer surface 21a of the belt body 2, the protrusion 22 is inserted between the guide portions 33 while abutting against each guide portion 33.

[0035] The interval between the pair of guide portions 33 may be the interval at which the protrusions 22 are press-fitted. In this case, it is preferable that the protrusions 22 are made of a material that is compressible and deformable in the belt longitudinal direction and the radial direction of the through-holes 221. If the protrusions 22 are press-fitted between the pair of guide portions 33 in this way, the profile 3 can be temporarily fixed to the belt main body 2 until the profile 3 is fixed to the belt main body 2 by the fixing member 4, and the work of attaching the profile 3 to the belt main body 2 becomes easier.

[0036] In this embodiment, the dimension L1 of the guide portion 33 in the belt width direction is smaller than the interval L2 between the engagement portions 32 (see FIG. 6). As a result, a gap S1 is formed between the guide portion 33 and each engagement portion 32 in the belt width direction.

[0037] Each of the pair of support portions 34 extends from an end of the bottom wall portion 311 in the belt longitudinal direction toward the outer surface 21a of the belt base 21 and also extends in the belt width direction. In this embodiment, each support portion 34 extends from one end of the bottom wall portion 311 to the other end in the belt width direction. Each support portion 34 has an abutment surface 341 at its tip (the end on the outer surface 21a side) that can come into surface contact with the outer surface 21a. In this embodiment, the abutment surface 341 is rectangular (strip-shaped) that is elongated in the belt width direction.

[0038] The fixing member 4 extends in the belt width direction and is inserted into each of the pair of engagement portions 32 while passing through the protrusions 22. In this embodiment, the fixing member 4 is a bolt extending in the belt width direction and having a male thread 41 at its tip (see FIG. 3). The outer diameter of this fixing member 4 (excluding the bolt head) is slightly smaller than the inner diameter of the corresponding portion of the through hole 322A of one engagement portion 32A and the inner diameter of the through hole 221 of the protrusions 22. The male thread 41 at the tip of the fixing member 4 is threadedly engaged with the female thread 322M of the through hole 322B of the other engagement portion 32B. As a result, when the profile 3 is fixed to the belt main body 2 (protrusions 22), the fixing member 4 is inserted through the through hole 221 of the protrusions 22 and the through hole 322A of one engagement portion 32A, and is threaded into the through hole 322B of the other engagement portion 32B.

[0039] In the profiled belt 1 configured as above, the profile 3 is attached to and detached from the belt body 2 as follows.

[0040] When attaching the profile 3 to the belt body 2, the profile 3 is moved toward the outer surface 21a of the belt body 2 (belt base 21) so that the protrusion 22 fits between a pair of engagement portions 32, and is then placed on the outer surface 21a.

[0041] At this time, the protrusion 22 fits between the pair of engaging portions 32 (see FIG. 4), thereby determining the approximate position of the profile 3 in the belt width direction relative to the belt main body 2. Furthermore, the protrusion 22 fits between the pair of guide portions 33 (see FIG. 5), thereby determining the position of the profile 3 in the belt longitudinal direction relative to the belt main body 2. As a result, when viewed from the belt width direction, the through-hole 221 of the protrusion 22 and the through-holes 322A, 322B of the engaging portions 32A, 32B coincide (i.e., are located on the same straight line).

[0042] Next, the fixing member 4 is inserted into each of the through holes 322A, 221, 322B in a direction from one engaging portion 32A toward the other engaging portion 32B in the belt width direction. Specifically, the fixing member 4 is inserted sequentially through the through hole 322A of one engaging portion 32A and the through hole 221 of the protruding portion 22, and then the fixing member 4 is rotated around the central axis to screw the tip portion (the portion where the male thread 41 is formed) into the through hole 322B of the other engaging portion 32B.

[0043] This fixes the profile 3 to the belt body 2. At this time, the contact surfaces 321 of the engagement portions 32 of the profile 3 and the contact surfaces 341 of the support portions 34 are in surface contact with the outer surface 21a of the belt body 2, respectively.

[0044] On the other hand, when removing the profile 3 from the belt main body 2, the fixing member 4 is rotated around the central axis (in the opposite direction to when it is screwed into the through hole 322B) to remove the tip portion from the through hole 322B of the other engaging portion 32B and also remove it from the through hole 221 of the convex portion 22 and the through hole 322A of the one engaging portion 32A.

[0045] Next, the profile 3 is moved in a direction from the inner surface 21b of the belt body 2 toward the outer surface 21a, and separated from the belt body 2. As a result, the profile 3 is removed from the belt body 2.

[0046] As described above, in the profiled belt 1 of this embodiment, the fixing member 4 is inserted and removed in the belt width direction during the installation and removal of the profile 3. Therefore, even if the distance between adjacent profiles 3 (convex portions 22) in the belt longitudinal direction is small when inserting or removing the fixing member 4, the adjacent profile 3 does not get in the way of the insertion or removal of the fixing member 4, which makes it easy to insert or remove the fixing member 4.

[0047] The profiled belt described above comprises a belt body 2, a profile 3 removably attached to the outer surface (back surface) 21a of the belt body 2, and a fixing member 4 that fixes the profile 3 to the belt body 2. The belt body 2 has a protrusion 22 protruding from the outer surface 21a, and the dimension of the protrusion 22 in the belt width direction (width direction of the belt body 2) is smaller than the dimension of the belt body 2. The profile 3 also has a storage portion (first portion) 31 adjacent to the protrusion 22 in the protruding direction of the protrusion 22, and a pair of engagement portions (second portions) 32 that extend from the storage portion 31 toward the outer surface 21a of the belt body 2 to a position where the fixing member 4 abuts against the outer surface 21a of the belt body 2, on both sides of the protrusion 22 in the belt width direction. The fixing member 4 extends in the belt width direction and is inserted into each of the pair of engagement portions 32 while passing through the protrusion 22. In this way, a pair of engagement portions 32 of the profile 3 abut against the belt main body 2 (outer surface 21a) on both sides of the convex portion 22 in the belt width direction, thereby suitably suppressing vibration of the profile 3 in the belt width direction when the profiled belt 1 is driven, etc.

[0048] Furthermore, in the profiled belt 1 of this embodiment, the protrusions 22 and the engagement portions (second portions) 32 each have a through-hole (hole) 221, 322 extending in the belt width direction and through which the fixing member 4 is inserted, and the profile 3 has a pair of guide portions 33 extending from the accommodation portion (first portion) 31 along the protrusion 22 and toward the outer surface (back surface) 21 a of the belt body 2 on both sides of the protrusion 22 in the belt longitudinal direction (longitudinal direction of the belt body 2). Therefore, when the profile 3 is placed on the outer surface 21 a of the belt body 2 so that the protrusion 22 fits between the pair of engagement portions 32, the pair of guide portions 33 aligns the profile 3 with the protrusion 22 in the belt longitudinal direction (i.e., aligns the through-holes 221, 322 of the protrusion 22 and the pair of engagement portions 32 in the belt longitudinal direction), which makes it easy to insert the fixing member 4 into the through-holes 221, 322.

[0049] Furthermore, in the profiled belt 1 of this embodiment, the profile 3 has a support portion 34 that extends from a position spaced apart in the belt longitudinal direction from the engaging portion (second portion) 32 in the accommodation portion (first portion) 31 toward the outer surface 21a (back surface) of the belt body 2 to a position where it abuts against the outer surface 21a. This also suppresses vibration of the profile 3 in the belt longitudinal direction.

[0050] Furthermore, in the profiled belt 1 of this embodiment, the protrusion 22 and one engagement portion 32A of the pair of engagement portions (second portions) 32 have through holes (insertion holes) 221, 322A penetrating in the belt width direction, the other engagement portion 32B of the pair of engagement portions 32 has a through hole (screw hole) 322B extending in the belt width direction from one engagement portion 32A toward the other engagement portion 32B and having a female thread on its inner circumferential surface, and the fixing member 4 is formed by a bolt extending in the belt width direction and having a male thread at its tip, which is inserted into the through holes 221, 322A of the protrusion 22 and one engagement portion 32A and is screwed into the through hole 322B of the other engagement portion 32B. With this configuration, the profile 3 can be fixed to and detached from the belt body 2 by inserting and removing the fixing member (bolt) 4.

[0051] The profiled belt of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the configuration of one embodiment can be added to the configuration of another embodiment, or part of the configuration of one embodiment can be replaced with the configuration of another embodiment. Furthermore, part of the configuration of one embodiment can be deleted.

[0052] Although the belt body 2 in the above embodiment is arranged in an endless state (so-called endless state), it is not limited to this configuration. The belt body 2 may be arranged in an extended state with both ends (so-called open-end state).

[0053] In the belt body 2 of the above embodiment, the belt base 21 and the protrusions 22 are separate members, and the protrusions 22 are joined (fused) to the belt base 21, but the present invention is not limited to this configuration. The belt base 21 and the protrusions 22 may be integral.

[0054] Furthermore, the joining of the protrusions 22 to the belt base 21 is not limited to fusion, but may be by adhesion, welding, etc. In other words, as long as the protrusions 22 are firmly joined to the outer surface 21a of the belt base 21, the joining method is not limited.

[0055] Furthermore, there is no limitation on the specific configuration of the profile 3. In other words, profiles 3 of various shapes can be attached to the belt body 2.

[0056] For example, as shown in Figures 7 to 9, the profile 5 has a first portion 51 adjacent to the protrusion 22 in the protruding direction of the protrusion 22, and an abutment portion 55 surrounding the periphery of the protrusion 22 and abutting against the outer surface 21a of the belt body 2.

[0057] Specifically, the first portion 51 has a plate-shaped base 52, a rotating portion 53 that is rotatable relative to the base 52, and a rotating shaft 54 ​​that engages the base 52 and the rotating portion 53.

[0058] The base portion 52 is a rectangular plate-shaped portion that extends in the belt longitudinal direction and the belt width direction and is long in the belt longitudinal direction, and has a protrusion 521 that protrudes in a direction away from the abutting portion 55.

[0059] The rotating portion 53 has a rotating portion main body 531 that is long in the belt width direction, and a pair of extension portions 532 that extend from both ends of the rotating portion main body 531 in the belt longitudinal direction toward the base portion 52 side.

[0060] The rotating portion main body 531 is a rectangular plate that is long in the belt width direction, and has a first convex rib 531a that protrudes toward the base 52 at one end in the belt width direction and extends in the belt longitudinal direction, and a second convex rib 531b that protrudes toward the opposite side of the base 52 at the other end in the belt width direction and extends in the belt longitudinal direction.

[0061] The pair of extension portions 532 are arranged at an interval corresponding to the dimension of the protrusion 521 in the belt width direction. Each of these extension portions 532 extends to a position where it overlaps with the protrusion 521 when viewed in the belt longitudinal direction. In other words, the protrusion 521 is located between the pair of extension portions 532.

[0062] The rotation shaft 54 ​​extends in the belt longitudinal direction, and penetrates the pair of extensions 532 and the protrusion 521 in the belt longitudinal direction so that the rotation portion 53 can rotate around the rotation shaft 54 ​​relative to the base portion 52.

[0063] The abutting portion 55 includes a pair of second portions 32A, 32B on both sides of the protrusion 22 in the belt width direction, extending from the first portion 51 toward the outer surface 21 a of the belt body 2 to a position where the second portions 32A, 32B abut against the outer surface 21 a of the belt body 2, and a pair of guide portions 33 on both sides of the protrusion 22 in the belt longitudinal direction, extending from the first portion 51 along the protrusion 22 toward the outer surface 21 a of the belt body 2. The abutting portion 55 is integral with the base portion 52 of the first portion 51.

[0064] In this abutment portion 55, one second portion 32A has a through hole (insertion hole) 322A that penetrates in the belt width direction, and the other second portion 32B has a through hole (screw hole) 322B that penetrates in the belt width direction and has a female thread formed on its inner surface.

[0065] The pair of second portions 32 and the pair of guide portions 33 are integrally connected, so that when the profile 5 is attached to the belt body 2, the abutment portion 55 surrounds the periphery of the protrusion 22.

[0066] The profile 5 described above can also be fixed to or removed from the belt body 2 by inserting or removing the fixing member 4.

[0067] Furthermore, although the profile 3 in the above embodiment is attached to one belt body 2, it may be configured to be attachable to multiple belt bodies 2 arranged in parallel. In this configuration, for example, as shown in Figures 10 to 13, the profile 6 includes a first portion 61 adjacent to the protruding portion 22 in the protruding direction of the protruding portion 22, multiple mounting portions 62 (the number of which corresponds to the number of belt bodies 2) attached to the corresponding belt bodies 2, and multiple fixing members 4 (the number of which corresponds to the number of mounting portions 62). In the example shown in Figures 10 to 13, the profile 6 is attached to two belt bodies 2 arranged in parallel.

[0068] Specifically, the first portion 61 extends in the belt width direction from a position overlapping with at least one belt body 2 to a position overlapping with the other belt body 2. This first portion 61 has, on a surface 61a opposite to the belt body 2, a groove portion 610 that extends in the belt width direction and is recessed toward the belt body 2. This groove portion 610 has a tapered portion 611 where the groove width gradually decreases toward the groove bottom, and a constant width portion 612 where the groove width is constant at each position in the groove depth direction.

[0069] Each of the multiple mounting portions 62 has a pair of engaging portions (second portions) 32A, 32B, a pair of guide portions 33, and a pair of support portions 34. The configurations of the engaging portions 32A, 32B, the guide portions 33, and the support portions 34 are the same as the configurations of the corresponding portions (portions with the same reference numerals) of the profile 3 in the above embodiment.

[0070] In the profile 6 described above, the attachment portions 62 can be fixed to or removed from the belt body 2 by inserting or removing the fixing members 4 in or from the attachment portions 62.

[0071] Furthermore, although the profile 3 in the above embodiment independently forms a space for accommodating an object to be conveyed, it may also be configured to form a space for accommodating an object to be conveyed in cooperation with an adjacent profile in the longitudinal direction of the belt. In this configuration, for example, as shown in Figures 14 to 18, the profile 7 includes a first portion 71 adjacent to the protrusion 22 in the protruding direction of the protrusion 22, a contact portion 55 disposed on the belt main body 2 side of the first portion 71, and an extension portion 72 extending from the first portion 71 and the contact portion 55 toward the adjacent profile 7 in the longitudinal direction of the belt.

[0072] The first portion 71 is a rectangular plate-shaped portion, and the abutting portion 55 has the same configuration as the example shown in Figures 7 to 9. That is, the abutting portion 55 includes a pair of second portions 32A, 32B and a pair of guide portions 33, one second portion 32A having a through hole (insertion hole) 322A, and the other second portion 32B having a through hole (screw hole) 322B.

[0073] The first portion 71 and the contact portion 55 are integrally configured to form a rectangular parallelepiped shape (prism-shaped portion 70) that is elongated in the belt width direction.

[0074] The extended portions 72 extend in the belt longitudinal direction from both ends of the prismatic portion 70 in the belt width direction. That is, the profile 7 has a pair of extended portions 72. A step portion 73 is formed at each connection portion between the extended portion 72 and the prismatic portion 70, and the dimension (step dimension) L3 (see FIG. 14) of this step portion 73 in the belt width direction corresponds to the dimension of the extended portion 72 in the belt width direction. Furthermore, each extended portion 72 extends to a position where its tip fits into the step portion 73 of the adjacent profile 7 in the belt longitudinal direction (see FIG. 17). As a result, the space (area) surrounded by the profile 7 and the prismatic portion 70 of the adjacent profile 7 becomes a storage space (storage area) S2 that stores conveyed goods.

[0075] The above-mentioned profiles 7 cooperate with adjacent profiles 7 to form a storage space S2 when the belt body 2 is located between the pulleys P, but when the belt body 2 is wound around the pulley P and curved, the tip end side of each extension portion 72 is positioned away from the belt body 2 (see Figure 18), allowing the belt body 2 to run smoothly even if the radius of curvature of the pulley P is small.

[0076] This profile 7 can also be fixed to or removed from the belt body 2 by inserting or removing the fixing member 4. [Explanation of symbols]
