  2. Description of the Related Art Conventionally, a belt-type conveyance device (hereinafter, also referred to as “conveyance device”) that conveys articles using a conveyor belt such as a modular chain (hereinafter also simply referred to as “belt”) is known (for example, Patent Documents). 1, 2 etc.). A conveyor belt (for example, a modular chain) of such a conveying apparatus is configured by connecting a plurality of belt constituent members (modules) in series in a rotatable manner via a hinge portion. The belt constituent member has a plurality of hinge portions protruding on both sides in the connecting direction. The protruding positions of the hinge portions on both sides are shifted by a half pitch in the hinge arrangement direction. When connecting adjacent belt constituent members, both hinge portions are inserted into the recesses between the other hinge portions. Then, by inserting a single pin through the aligned holes with the holes of both hinge portions aligned, adjacent belt constituent members are connected so as to be rotatable about the pins (for example, patents). Literature 1, 2 etc.).

  However, in the assembly process of rotatably connecting the adjacent belt constituent members 70 shown in FIG. 26, the first hinge portion 72 and the second hinge portion 73 extending on both sides of the base portion 71 should be connected. The 1st hinge part 72 and the 2nd hinge part 73 are inserted in the recessed part between the other hinge parts. At this time, as shown in FIG. 26, the holes 72a and 73a (pin holes) of both the hinge portions 72 and 73 may be displaced. This is because the holes 72a and 73a are aligned at a position where the insertion depth of the hinge portions 72 and 73 into the recess is shallower than the depth of the recess for some reason. For this reason, since the pins cannot pass through the holes 72a and 73a as they are, the operator has to perform the work of inserting the pins into the holes 72a and 73a after aligning the holes 72a and 73a. Therefore, the troublesome positioning of the holes 72a and 73a has caused a reduction in work efficiency when the conveyor belt is assembled. The belt constituent member is provided with a meshing portion 74 that can mesh with a tooth portion of a sprocket (not shown).

  In addition, even in a conveyor belt other than the modular chain, there is a similar problem in a conveyor belt that is assembled by connecting adjacent belt constituent members by inserting pins into holes in both hinge portions.

  The present invention has been made in order to solve the above-mentioned problems, and the object thereof is to both insert a pin when connecting two adjacent belt constituent members in a conveyor belt at respective hinge portions. It is an object of the present invention to provide a conveyor belt, a belt component, and a belt type conveying device that can easily align the holes of the hinge portion of the belt.

Hereinafter, means for solving the above-described problems and the effects thereof will be described.
A conveyor belt that solves the above problems is a conveyor belt formed by connecting a plurality of belt constituent members to adjacent belt constituent members and hinges in a rotatable state, and the belt constituent members A long base, a plurality of hinges extending on both sides in a direction intersecting with the longitudinal direction of the base, and when inserting the hinge of another belt constituent member into a recess between the hinges A restricting portion that abuts the hinge portion at a position before the bottom of the concave portion and restricts further movement of the hinge portion toward the insertion side. In the state of contact, the two belt constituent members are positioned at positions where the holes of both the hinge portions fit together so that the pins can be inserted.

  According to this configuration, when both the hinge portions are inserted into the recesses between the mating hinges in order to connect the belt constituent members, the hinge portions abut on the restricting portion at a position before the bottom of the recesses and beyond. Movement to the insertion side is restricted. As a result, the two belt constituent members are positioned at positions where the holes of the hinge portions of the two belt members can be inserted. Therefore, careful work is not required to align the holes of the hinge portions, so that workability is improved. Then, a pin may be inserted into the aligned hole.

In the conveyor belt, at least two of the restriction portions are provided so as to be able to contact the hinge portion at at least two positions in the longitudinal direction of the belt constituent member.
According to this configuration, since the hinge portion contacts at least two restricting portions in at least two places in the longitudinal direction of the belt constituent member, both belt constituent members are held in a parallel posture at the time of contact. For example, if there is only one restricting portion, both belt constituent members may be tilted at the time of contact, and in this case, holes that are out of position among all the holes are generated. However, since the hinge part and the restricting part abut at least two places in the longitudinal direction of the belt constituent member, it is avoided that the postures of both belt constituent members are inclined at the time of the abutment, and a plurality of hinge parts to be connected The holes can be aligned in all cases.

In the conveyor belt, the restriction portion is provided on a side surface of all the hinge portions.
According to this configuration, even if the belt constituent member is cut at any position in the longitudinal direction according to the required belt width, the regulating portion is always provided on the side surface of the hinge portion of the belt constituent member to be cut and used. Exists. For this reason, regardless of where the belt constituent member is cut in accordance with the belt width, both holes can be aligned at the contact portion between the hinge portion and the regulating portion.

  In the conveyor belt, the belt constituent member has a meshing portion that can be engaged with a tooth portion of a sprocket, and the restricting portion is in a position not in contact with the sprocket when the meshing portion is engaged with the tooth portion. Is provided.

  According to this configuration, in a state where the meshing portion of the belt constituent member is engaged with the tooth portion of the sprocket, the restricting portion does not contact the tooth portion, so that the restricting portion interferes with the transmission of power from the sprocket to the belt constituent member. There is nothing. Moreover, it is easy to avoid damage to the restricting portion due to contact with the tooth portion.

  In the conveyor belt, the base portion of the belt component member is provided with a meshing portion that can be engaged with a tooth portion of a sprocket, and the restricting portion includes the base portion into which the pin is inserted in a side wall of the hinge portion. It is provided at a position on the bottom side below the pitch line connecting the holes of the hinge portions on both sides of the sandwiched side.

According to this configuration, when the conveyor belt back-bends, the restricting portion does not get in the way, so a large back-bend angle can be secured on the conveyor belt.
A belt constituent member that solves the above-described problem is a belt constituent member that constitutes the conveyor belt, and extends to one of a long base portion and both sides in a direction crossing the longitudinal direction of the base portion. A plurality of first hinge portions; a plurality of second hinge portions extending to the other side of the both sides of the base portion; and the restriction portion in the conveyor belt.

According to this structure, the same operation effect as said conveyor belt can be acquired in the assembly operation which connects two belt structural members.
The belt type conveying device that solves the above-mentioned problem is that the conveyor belt and the endless conveyor belt are wound at two positions apart from each other by a predetermined distance and one of the two positions is located. A plurality of sprockets driven by a power source. According to this structure, the same effect as said conveyor belt can be acquired.

  ADVANTAGE OF THE INVENTION According to this invention, when connecting two belt structural members which adjoin each other in a conveyor belt with each hinge part, the hole of both hinge parts which should insert a pin can be aligned easily.

(First embodiment)
Hereinafter, a conveyor belt according to a first embodiment and a belt-type conveyance device equipped with the same will be described with reference to the drawings.

  As shown in FIG. 6, the belt-type transport device 11 has a function of transporting an article W placed on an article transport surface 12 a on the upper surface thereof in the transport direction X by rotating a belt-shaped conveyor belt 12. ing. The conveyor belt 12 is configured by an endless (annular) modular chain (modular conveyor belt) having a predetermined width and a predetermined length. The conveyor belt 12 is made of plastic in this example.

  In the belt-type transport device 11, a pair of rotary shafts 13 can be rotated via bearings (both not shown) attached to a frame at positions on both sides that are separated by a predetermined distance in the transport direction X. It is supported. A plurality of sprockets 14 are fitted to the pair of rotating shafts 13 at positions spaced apart from each other in the axial direction in a state where they can rotate together. A plurality of tooth portions 14 a are formed at a constant pitch on the outer periphery of each sprocket 14. The conveyor belt 12 is wound around the sprocket 14 with the meshing portion (engagement convex portion 27 in FIG. 4) meshing with the tooth portion 14a.

  As shown in FIG. 6, a motor 15, which is an example of a power source, is connected to the rotation shaft 13 of the drive-side sprocket 14 located downstream in the transport direction X (right side in FIG. 6) via a power transmission mechanism (not shown). Are connected in a state where power can be transmitted. Therefore, the rotational force of the sprocket 14 that rotates when the motor 15 is driven is transmitted to the conveyor belt 12 through meshing with the tooth portions 14a, so that the conveyor belt 12 circulates. The articles W on the conveyor belt 12 are conveyed in the conveyance direction X by this circulation. The conveyor belt 12 can also rotate in the direction opposite to the conveyance direction X by driving the motor 15 in the reverse direction.

  As shown in FIG. 6, a plurality of rollers 16 that support the sag of the conveyor belt 12 are disposed below the conveyor belt 12. The conveyor belt 12 can be bent (back bend) in the direction opposite to the bending direction of the portion wound around the sprocket 14 so that it can be bent along the arc surface of the roller 16.

  Next, the configuration of the conveyor belt 12 will be described with reference to FIGS. The conveyor belt 12 has a connecting structure for rotatably connecting two belt constituent members 20 adjacent to each other in the transport direction X, and is the same between the other adjacent belt constituent members. Any two adjacent belt components 20 shown and their connection structure will be described. Further, in the belt width direction Y of the conveyor belt 12 shown in FIG. 1, the belt constituent members 20 are merely arranged in the belt width direction Y in the number of rows necessary for the belt width. The connection structure for one row of the belt component member 20 will be described.

  The two adjacent belt constituent members 20 constituting the conveyor belt 12 shown in FIG. 1 have a long base portion 21 extending along the longitudinal direction y (belt width direction Y) and the longitudinal direction of the base portion 21. A plurality of first hinge portions 22 extending to one side (downstream side in the transport direction X in FIG. 1) of both sides of the short direction x intersecting the direction, and a plurality of second hinge portions extending to the other side 23. The first hinge part 22 and the second hinge part 23 are arranged at a constant pitch in the belt width direction Y (longitudinal direction y). In the state shown in FIGS. 1 and 2, the two belt constituent members 20 are a state where the first hinge portion 22 and the second hinge portion 23 on the connection side are slightly inserted into the recesses 24 between the hinge portions on the other side, respectively. Is arranged. The pin 22a (pin hole) formed in the first hinge part 22 and the hole 23a (pin hole) formed in the second hinge part 23 (see FIG. 3) are aligned in this state. By inserting 30, the two belt constituent members 20 are connected so as to be rotatable around the pin 30. The pin 30 has a length substantially equal to the belt width of the conveyor belt 12, and one common pin is inserted into the plurality of belt constituent members 20 arranged in the belt width direction Y.

  The conveyor belt 12 of the present embodiment has a shape in which the interval between the adjacent belt constituent members 20 is increased for the purpose of increasing the opening of the article conveying surface 12a and reducing the radius of the back bend. Of course, it may be due to other reasons that the distance between adjacent belt constituent members 20 is large. For this reason, the depth at which the hinges 22 and 23 are inserted into the recesses 24 in order to align the positions of the holes 22a and 23a with respect to the depth of the recesses 24 substantially equal to the extension length of the hinges 22 and 23 is reduced. ing.

  On the side surfaces of the hinge portions 22 and 23, positioning is performed so that the hinge portions 22 and 23 of both belt constituent members 20 and 20 are aligned so that the pins 30 can be inserted into the respective holes 22a and 23a when the belt is assembled. Restricting portions 25 and 26 are provided. The restricting portions 25 and 26 in this example are formed of protrusions that can come into contact with the hinge portions 22 and 23. The detailed configuration of these restricting portions 25 and 26 will be described later.

  As shown in FIGS. 1 and 4, an engagement convex portion 27 as an example of a meshing portion is formed on a side surface of the belt component member 20 at a position corresponding to the base portion 21. As shown in FIG. 4, the engagement convex portion 27 is a central position in the lateral direction x between the holes 22 a and 23 a (in other words, the pins 30) of the hinge portions 22 and 23 on the side surface of the belt component member 20. Is arranged. In other words, the engagement protrusions 27 are arranged at the same pitch as the pins 30 at the center position between the pins 30 in the longitudinal direction of the conveyor belt 12. Further, the engagement convex portion 27 is formed in a predetermined shape capable of meshing with the tooth portion 14 a of the sprocket 14. The engagement convex portion 27 of the present example has a shape that becomes narrower toward the bottom side (lower side in the figure) of the belt constituent member 20 in a side view shown in FIG. It has an inverted triangular shape toward

  Further, as shown in FIG. 4, the restricting portion 26 is disposed at a position slightly closer to the article conveying surface 12 a on the side surface of the second hinge portion 23. In addition, when the two belt constituent members 20 are connected, the restricting portion 26 can contact the first hinge portion 22 of the other (adjacent) belt constituent member 20 connected to the one belt constituent member 20. Is arranged. When the positions of both the holes 22a and 23a are in a state in which the pin 30 can be inserted, the first hinge portion 22 abuts the restricting portion 26 at a position before the bottom of the concave portion 24, and the further insertion side Movement to is regulated.

  1 and 2 also has a predetermined shape (substantially inverted triangular shape) similar to that of the restricting portion 26. And the control part 25 is arrange | positioned in the location near the article conveyance surface 12a in the side surface on the opposite side to the side surface in which the control part 26 in the 2nd hinge part 23 was formed in the 1st hinge part 22. FIG. In addition, when the two belt constituent members 20 are connected to each other, the restricting portion 25 can be brought into contact with the second hinge part 23 of the other (adjacent) belt constituent member 20 connected to the one belt constituent member 20. Is arranged. When the positions of both holes 22a and 23a are such that the pin 30 can be inserted, the second hinge portion 23 comes into contact with the restricting portion 26 at a position closer to the front side than the bottom of the concave portion 24 and further to the insertion side. Movement is restricted. As described above, the two belt constituent members 20 have the first hinge portion 22 in contact with the restricting portion 26 and the second hinge portion 23 in contact with the restricting portion 25, whereby the holes 22 a of both the hinge portions 22, 23. , 23a are positioned so that the pin 30 can be inserted.

  As shown in FIG. 5, at the portion of the conveyor belt 12 that meshes with the sprocket 14, the engagement convex portion 27 of the belt component member 20 meshes with the tooth portion 14 a of the sprocket 14. Specifically, the sprocket 14 has a pair of tooth portions 14a that form an engagement concave portion 14b that can be engaged with the engagement convex portion 27 between the engagement convex portions 27 on the conveyor belt 12 side. Are arranged in The engaging convex part 27 meshes with the tooth part 14a while being inserted into the engaging concave part 14b. Further, as shown in FIG. 5, the restricting portion 26 is disposed at a position where the restricting portion 27 of the belt component member 20 does not come into contact with the tooth portion 14 a under a state where the engaging convex portion 27 is engaged with the tooth portion 14 a. In other words, the restriction portions 25 and 26 are disposed on the side surfaces of the hinge portions 22 and 23 closer to the article transport surface 12a (closer to the upper surface) to prevent the restriction portions 25 and 26 from coming into contact with the tooth portion 14a. Because. Here, among the plurality of sprockets 14 on the rotating shaft 13, the pair of teeth 14a of the inner row of the sprockets 14 disposed between the outer two sprockets 14 has the base 21 inserted into the engaging recess 14b. In the state, it is engaged with a pair of recessed parts 24 located on both sides of the base 21. The restricting portion 25 is disposed on the side surface of the first hinge portion 22 at a position where it does not come into contact with the tooth portion 14 a inserted into the recess 24. In the present embodiment, the base portion 21 that engages with the sprocket tooth portion constitutes an example of the meshing portion in the same manner as the engagement convex portion 27.

  As shown in FIG. 3, before assembling the conveyor belt 12, the portion where the two adjacent belt constituent members 20, 20 shown in FIGS. 1, 2 are connected to the two belt constituent members 20, 20. It is comprised with the pin 30 of a book. Here, a detailed configuration of the belt component member 20 will be described with reference to FIGS.

  As shown in FIGS. 7, 9, and 10, the plurality of first hinge portions 22 extend toward one side in the lateral direction x orthogonal to the longitudinal direction y of the base portion 21. The first hinge portion 22 has a plate-like portion extending toward the base 21, and a portion closer to the tip than the plate-like portion bulges to one side in the longitudinal direction y (right side in FIGS. 7 and 9). The annular portion 28 is thicker than the plate-like portion. Similarly, the plurality of second hinge portions 23 extend toward the other side in the short direction x orthogonal to the longitudinal direction y of the base portion 21. In the second hinge portion 23, the portion closer to the base 21 extends slightly obliquely in a plate shape, and the portion closer to the tip than the plate-like portion is on the other side in the longitudinal direction y (left side in FIGS. 7 and 9). The annular portion 28 bulges and is thicker than the plate-like portion.

  As shown in FIG. 10, the plate-like portion of the first hinge portion 22 near the base 21 forms an angle slightly smaller than 90 degrees (for example, 80 to 85 degrees) with respect to the longitudinal direction y from the base 21. It extends to. The annular portion 28 bulges from the surface on the acute angle side in the plate-like portion that is slightly inclined at the distal end portion of the first hinge portion 22. On the other hand, the plate-like portion near the base 21 of the second hinge part 23 is at an angle slightly smaller than 90 degrees (for example, 80 to 85 degrees) from the base 21 with respect to the longitudinal direction y of the first hinge part 22. It extends in a direction inclined to the opposite side to the plate-like part. The annular portion 28 bulges from the acute angle side surface of the plate-like portion that is slightly inclined at the tip portion of the second hinge portion 23. For this reason, the bulging direction of the annular portion 28 at the tip portions of the hinge portions 22 and 23 is the opposite side.

  As described above, the plate-like portions of the hinge portions 22 and 23 extend while being inclined to the opposite side, and the annular portion 28 bulges from the acute-angle-side surface of the plate-like portion. The annular part 28 on the side of the part 22 and the annular part 28 on the side of the second hinge part 23 are located at a half pitch shift in the longitudinal direction y of the base part 21. Therefore, in the longitudinal direction y of the base portion 21, the annular portion 28 of the first hinge portion 22 is disposed at a position corresponding to the recess 24 between the annular portions 28 of the second hinge portion 23, and the annular shape of the second hinge portion 23 is The portion 28 is disposed at a position corresponding to the recess 24 between the annular portions 28 of the first hinge portion 22. Both end surfaces of the annular portion 28 are surfaces perpendicular to the longitudinal direction y of the base portion 21. The opening of the recess 24 between the annular portions 28 is formed to be slightly wider than the width of the annular portion 28, and a gap for play when the annular portion 28 is inserted into the recess 24 is secured.

  The two belt constituent members 20 are assembled in a state in which the respective annular portions 28 face each other in the longitudinal direction y in a state where the hinge portions 22 and 23 are inserted into the concave portion 24 on the other side to a predetermined depth. At the time of this assembly, if the two belt constituent members 20 are arranged so as to face each other on a horizontal plane and the two belt constituent members 20 are brought close to each other while keeping the base portions 21 in parallel, the hinge portions 22 and 23 are respectively It is inserted into the counterpart recess 24. And the circular holes 22a and 23a formed in the center part of the cyclic | annular part 28 because the hinge parts 22 and 23 contact | abut to the control parts 25 and 26 and the movement to the further recessed part 24 is controlled, The pin 30 is positioned so that it can be inserted.

  As shown in FIG. 10, the restricting portion 25 is formed on the surface of the first hinge portion 22 opposite to the side on which the annular portion 28 bulges. The restricting portion 26 is formed on the surface of the second hinge portion 23 opposite to the side on which the annular portion 28 bulges. As shown in FIG. 12, from the state where the two belt constituent members 20 are horizontally arranged with the first hinge portion 22 and the second hinge portion 23 facing each other, both the hinge portions 22 and 23 are recessed portions on the other side. 24 so as to be inserted. As shown in FIGS. 1, 2, and 13, when the second hinge part 23 of the other belt component member 20 is inserted into the recess 24 between the first hinge parts 22, the first hinge part 22 is Further entry is restricted by hitting the restricting portion 26, and further entry is restricted by the second hinge portion 23 hitting the restricting portion 25. In a state where further approach is restricted by the restriction by both restriction portions 25 and 26, the hole 22a of one belt constituent member 20 and the hole 23a of the other belt constituent member 20 coincide as shown in FIG. It is supposed to be. In this restricted state, the holes 22a and 23a do not necessarily have to be positioned in a state in which the respective axes coincide with each other, and need only be positioned so that the pin 30 can be inserted.

  Further, the shape of the engagement convex portion 27 formed on the side surface of the belt component member 20 shown in FIG. 11A and the sectional shape of the base portion 21 shown in FIG. 11B (for example, A- in FIG. 10). (A line cross section) is substantially the same. In detail, in FIG.11 (b), the cross-sectional shape of the base 21 is a substantially inverted triangle of the same shape as the engagement convex part 27 shown to Fig.11 (a).

  This is because the belt constituent member 20 of the present embodiment has a part of the belt constituent members 20 arranged in the belt width direction Y at predetermined positions in the longitudinal direction y in order to make the conveyor belt 12 have a necessary belt width. This is because it may be cut and used. Even if the base portion 21 of the belt component member 20 is cut between any hinge portions in the longitudinal direction y, an engagement convex portion 27 similar to that shown in FIG. .

  Further, it is set so that two or more restricting portions always remain in the longitudinal direction y regardless of where the belt constituent member 20 is cut according to the required belt width. In the present embodiment, as an example, restricting portions 25 and 26 are provided on the side surfaces of all the hinge portions 22 and 23, respectively.

  As shown in FIG. 14A, a reference that is in contact with the bottom side end portions (lower end) of the inverted triangular regulation portions 25 and 26 and that is parallel to the center line passing through the center in the thickness direction on the side surface of the belt component member 20. An angle θ1 formed by the line L and the abutted surface 26a that is a surface with which the hinge portion of the other (other party) belt component member abuts is set to a relatively large angle of, for example, 50 degrees or more. Here, the angle θ1 is more preferably 70 degrees or more, and the angle θ1 in the present embodiment is set to an acute angle of 70 degrees or more. Note that the angle θ1 of the abutted surface 26a is set in accordance with the inclination angle of the abutting surface of the hinge portion 22 on the counterpart side when bent at the maximum back bend angle. The surface abuts against the abutting surface 26a.

  As shown in FIG. 14B, it is possible to bend (back-bend) the two adjacent belt constituent members 20 and 20 in the direction opposite to the bending direction of the portion wound around the sprocket 14. Yes. That is, the restricting portions 25 and 26 provided at positions where the hinge portions 22 and 23 can be brought into contact with each other for assembly work have a shape that allows the hinge portions 22 and 23 to turn to the back bend side. In the example of the present embodiment, the maximum back bend angle θ1 is necessary to bend the conveyor belt 12 along the arc surface of the roller 16. If the roller 16 is not provided, the angle θ1 may be less than 50 degrees.

Next, the operation of the conveyor belt 12 and the belt component 20 will be described.
In the process of assembling the conveyor belt 12, the two belt constituent members 20, 20 to be connected to each other are brought close to each other so that the hinge portions 22, 23 are inserted into the concave portion 24 on the other side, and the holes 22 a, 23 a. Align. That is, as shown in FIG. 3 and FIG. 12, the two belt constituent members 20 are aligned in the longitudinal direction y, and both hinge portions 22 and 23 to be connected are opposed to the concave portion 24 on the other side. Place on the workbench.

  Next, from the state shown in FIG. 3 and FIG. 12, at least one of the two belt constituent members 20 and 20 is moved horizontally on the work table in a direction approaching each other, and both the hinge portions 22 and 23 are moved to each other. Insert into the side recess 24. At this time, as shown in FIG. 13, the first hinge portion 22 inserted into the recess 24 abuts on the restricting portion 26, and at the same time, the second hinge portion 23 abuts on the restricting portion 25. For this reason, both the hinge parts 22 and 23 are contact | abutted to the control parts 25 and 26, respectively, and the movement to the further insertion direction (approach direction) is controlled, The two belt structural members 20 and 20 are shown in FIG. Positioned by position. In the positioning state shown in FIG. 13, the holes 22a and 23a of both the hinge portions 22 and 23 coincide. For this reason, the operator positions the holes 22a and 23a while adjusting the insertion depth of the hinges 22 and 23 into the recess 24 while visually confirming the positions of the holes 22a and 23a. There is no need to match. Then, the pin 30 is inserted into the holes 22a and 23a that coincide with each other by the positioning by the restriction portions 25 and 26. Both ends of the pin 30 are prevented from coming off at both sides in the belt width direction Y of the conveyor belt 12. And the conveyor belt 12 is assembled by repeating the same connection operation | work with the adjacent belt structural member 20 about the other belt structural member 20 which comprises the conveyor belt 12. FIG.

  Further, in the belt-type transport device 11 manufactured by winding the assembled conveyor belt 12 around the sprocket 14, the tooth portion 14 a of the sprocket 14 meshes with the engaging convex portion 27 and the base portion 21. At this time, since the restricting portions 25 and 26 are disposed at positions near the article conveying surface 12a on the side surface of the belt component member 20, contact with the tooth portion 14a is avoided as shown in FIG.

  Further, the lower part of the conveyor belt 12 is supported by the roller 16 to support the sag. The angle θ1 formed by the contact surfaces 25a and 26a of the restricting portions 25 and 26 with respect to the reference line is 50 degrees or more. Set to. For this reason, since the conveyor belt 12 can be bent at a relatively large angle, the conveyor belt 12 can be bent along the arc surface of the roller 16. For example, detachment of the conveyor belt 12 from the roller 16 is suppressed.

According to the embodiment described above in detail, the following effects can be obtained.
(1) At the time of an assembly operation for connecting any two adjacent belt constituent members 20 constituting the conveyor belt 12, the hinge portions 22, 23 are placed in the recessed portion 24 on the other side, and the hinge portions 22, 23 are placed in the recessed portion 24. Further, the movement toward the insertion side is restricted by abutting against the restriction portions 25 and 26 at a position before the bottom. Therefore, if the hinge parts 22 and 23 are inserted to a control position, both holes 22a and 23a can be aligned in the position. For this reason, the troublesome operation | work which an operator aligns both holes 22a and 23a visually can be made unnecessary.

  (2) Since the restricting portions 25 and 26 are provided on all the hinge portions 22 and 23, the two belt constituent members 20 can be brought into contact with each other at two or more locations in the longitudinal direction y during assembly. In particular, the hinge portions 22 and 23 abut on the restricting portions 25 and 26 at least at two locations including positions on both sides of the two belt constituent members 20 with the center position in the longitudinal direction y therebetween. For example, when there is one contact portion in the longitudinal direction y, the two belt constituent members 20 contact with each other in an inclined posture during positioning, which may cause the positions of some of the holes 22a and 23a to shift. On the other hand, in the present embodiment, the adjacent belt constituent members 20 abut on each other in at least two places in the longitudinal direction y, so that all the holes 22a and 23a can be aligned.

  (3) Since the restricting portions 25 and 26 are provided on all the hinge portions 22 and 23, the center position in the longitudinal direction y is sandwiched regardless of where the belt constituent member 20 is cut in the longitudinal direction y. The hinge portions 22 and 23 abut against the restricting portions 25 and 26 at at least two places including positions on both sides. For this reason, all the holes 22a and 23a can be aligned regardless of where the belt component member 20 is cut in the longitudinal direction y.

  (4) Since the restricting portions 25 and 26 are provided at positions where they do not contact the tooth portion 14a of the sprocket 14, interference between the restricting portions 25 and 26 and the sprocket 14 can be avoided. In particular, in the present embodiment, the engaging convex portion 27 and the base portion 21 are engaged with the tooth portion 14a of the sprocket 14 and the tooth portion 14a is engaged from the bottom side of the belt component member 20, but the restricting portions 25 and 26 are provided. The belt component 20 is disposed at a position near the article conveying surface 12a on the opposite side to the bottom side that is the engagement side of the tooth portion 14a. For this reason, even if the restricting portions 25 and 26 are provided on the wall surfaces (side surfaces of the hinge portions 22 and 23) forming the area in which the tooth portion 14a is engaged, the contact between the restricting portions 25 and 26 and the tooth portion 14a. Can be avoided.

  (5) Since the restricting portions 25 and 26 have a shape that is wider on the article conveying surface 12a side than the bottom side of the belt component member 20 (for example, an inverted triangle shape), the restricting portions 25 and 26 are relatively relatively arranged in a narrow area with many restrictions. High strength can be secured. For example, if the restricting portion is a rectangle having a shape and size that does not contact the tooth portion 14a of the sprocket 14, for example, the width is as narrow as the bottom side (the width of the lower end portion of the inverted triangle) of the restricting portions 25 and 26 of the present embodiment. It must be rectangular. In this case, only a low strength can be obtained with a narrow rectangular regulating portion. For this reason, there is a possibility that the restricting portion may be damaged when the hinge portion slightly hits the thin rectangular restricting portion during assembly work. On the other hand, since the regulation parts 25 and 26 of this embodiment can ensure the width | variety wider than the width | variety of the bottom part side in the part near the article conveyance surface 12a, it can ensure high intensity | strength compared with the above-mentioned rectangular regulation part.

  (6) The angle θ1 formed between the contact surfaces 25a and 26a where the restricting portions 25 and 26 are in contact with the hinge portions of the adjacent belt constituent member 20 and the reference line L is set to a relatively large value (for example, 50 degrees or more). . In particular, in this embodiment, the angle θ1 is set to 70 degrees or more. Therefore, the maximum back bend angle when the conveyor belt 12 is bent in the direction opposite to the bending direction of the sprocket 14 can be secured relatively large. For this reason, the conveyor belt 12 can be bent along the arc surface of the roller 16. For example, the conveyor belt 12 can be securely held by the arc surface of the roller 16 and the pressure received by the conveyor belt 12 from the roller 16 can be reduced. For example, the conveyor belt 12 is excessively brought into contact with the roller 16 due to close contact with the roller 16. The situation where an excessive pressure is applied can be avoided. Further, since the conveyor belt 12 can be back-bended at a relatively large angle, the maintenance of the conveyor belt 12 and the like are facilitated.

(Second Embodiment)
Next, the conveyor belt of 2nd Embodiment is demonstrated, referring FIGS. 15-25.
As shown in FIG. 15, the conveyor belt 12 of the second embodiment includes a plurality (but only two are shown) of belt constituent members 40. As in the first embodiment, the belt member connection structure is simply the same connection structure repeated in the transport direction X, and the belt width direction Y includes a required number of belt component members corresponding to the required belt width. They are only placed next to each other. For this reason, in the following description, the arbitrary two belt structural members which comprise the conveyor belt 12 of this 2nd Embodiment, and its connection structure are demonstrated.

  Two adjacent belt constituent members 40 constituting the conveyor belt 12 are each composed of a long base 41 extending along the longitudinal direction y and both sides of the lateral direction x intersecting the longitudinal direction y of the base 41. The first hinge portion 42 and the second hinge portion 43 extend in a plurality. As shown in FIGS. 15 and 17, the plurality of first hinge portions 42 extend to one side of both sides in the lateral direction x with respect to the base portion 41, and the plurality of second hinge portions 43 extend to the base portion 41. It extends to the other side in the short direction. The first hinge portions 42 are arranged at regular intervals in the longitudinal direction y of the belt constituent member 40, and a recess 44 having a depth corresponding to the extension length is formed between the first hinge portions 42. Yes. Similarly, the second hinge portions 43 are arranged at the same constant intervals as the first hinge portions 42 in the longitudinal direction of the belt constituent member 40, and a depth corresponding to the extension length is set between the second hinge portions 43. A concave portion 44 is formed. The first hinge portion 42 and the second hinge portion 43 are arranged at positions that are shifted from each other by a half pitch at a pitch equal to the longitudinal direction y of the belt constituent member 40.

  Then, as shown in FIG. 15, the first hinge part 42 of one belt constituent member 40 and the second hinge part 43 of the other (adjacent) belt constituent member 40 are respectively recessed between the hinge parts on the other side. The pin 30 is inserted into the matching holes 42a and 43a (see FIG. 20) of both the hinge portions 42 and 43 in a state where the pin 30 is inserted to a predetermined depth. And the conveyor belt 12 is comprised by connecting the some belt structural member 40 in series by the connection structure which connects the two belt structural members 40 by the pin 30 so that rotation is possible.

  Here, in the conveyor belt 12 of this embodiment, as in the first embodiment, adjacent belts are used for the purpose of enlarging the opening of the article conveyance surface 12a (conveyance surface) and the purpose of reducing the radius of the back bend. The configuration is such that the interval between the constituent members 20 is increased. Of course, another reason may be sufficient as the reason which makes the space | interval of the adjacent belt structural member 20 large. For this reason, the depth at which the hinge portions 42, 43 are inserted into the recess 44 in order to align the positions of the holes 42a, 43a with respect to the depth of the recess 44 substantially equal to the extension length of the hinge portions 42, 43 is reduced. ing.

  In the first embodiment, since the belt component 20 is configured to be used by cutting the belt component 20 at an arbitrary position in the longitudinal direction y, the restricting portions 25 and 26 remain so as to remain where they are cut. The restricting portions 25 and 26 are provided on the side surfaces of all the hinge portions 22 and 23, respectively. On the other hand, in the second embodiment, the belt component 40 is basically not used for cutting. For this reason, as shown in FIGS. 15 to 17, the same direction as the direction in which one restricting portion 45 extends on the bottom surface of one recess 44 among the recesses 44 between the first hinge portions 42. One restricting portion 46 protrudes from the bottom surface of one of the recesses 44 between the second hinge portions 43 in the same direction as the extending direction of the second hinge portion 43. The two restricting portions 45 and 46 are arranged at two different positions in the longitudinal direction y of the belt constituent member 40. In particular, the two restricting portions 45 and 46 are respectively arranged at predetermined intervals at positions on both sides of the center position in the longitudinal direction y of the belt constituent member 40. In this example, the two restricting portions 45 and 46 are arranged at positions on the inner side from both ends by about ¼ of the total length in the longitudinal direction y of the belt constituent member 40.

  As shown in FIGS. 17 to 20, the base portion 41 of the belt component member 40 can be engaged with the tooth portions 14 a of the sprocket 14 at predetermined locations in the longitudinal direction y (predetermined two locations in this example). An engaging recess 47 is formed as an example of the meshing portion. That is, the position of the engaging recess 47 is predetermined in the belt width direction Y of the conveyor belt 12 (that is, the longitudinal direction y of the belt constituent member 40), and the belt constituent member 40 is basically cut somewhere in the longitudinal direction. It is not used. For this reason, in this embodiment, when the first hinge part 42 and the second hinge part 43 to be connected are respectively inserted into the recesses 44 of the mating belt constituent member 40, the two in the longitudinal direction y of the belt constituent member 40. The hinge portions 42 and 43 are in contact with the restricting portions 45 and 46 at a position before the bottom of the concave portion 44 so that further movement to the insertion side is restricted.

  As shown in FIGS. 15, 17, and 19, in particular, the restriction portions 45 and 46 are respectively located at both sides of the center position in the longitudinal direction y of the belt component member 40 with a predetermined interval and short. In the direction x, they are located on opposite sides of the base 41. Further, as shown in FIG. 16, the restricting portion 45 is disposed at a position on the bottom side below the pitch line PL, which is an imaginary line connecting the axes of the holes 42a and 43a (that is, the pin 30) in a side sectional view in FIG. Has been. Although not shown, the other restricting portion 46 is also arranged at a position on the bottom side below the pitch line PL.

  This is because when the two belt constituent members are rotated about the pin 30, the restricting portions 45 and 46 are arranged at positions where the rotation trajectories of the hinge portions 42 and 43 are avoided. For this reason, when the two belt constituent members 40 are back-bended, the restricting portions 45 and 46 do not interfere with the rotation of the two belt constituting members 40 on the back bend side regardless of the presence or absence of the restricting portions 45 and 46. The range is the same, and the maximum back bend angle necessary for the conveyor belt 12 can be secured (see FIG. 23).

  Further, the protruding amount of the restricting portions 45 and 46 is such that both the hinge portions 42 and 43 on the other side are in contact with the restricting portions 45 and 46 when the mating hinge portions 42 and 43 are inserted into the recess 44 and further movement is restricted. The holes 42a and 43a of the hinge portions 42 and 43 are set to values to be aligned. That is, in a state where the two belt constituent members 40 are positioned by the restricting portions 45 and 46, the hole 42a of the first hinge portion 42 and the hole 43a of the second hinge portion 43 are aligned within a range where the pin 30 can be inserted. It will be.

  Further, an engagement recess 47 into which the tooth portion 14 a of the sprocket 14 shown in FIG. 6 is engaged is formed in the base portion 41. In the first embodiment, the tooth portions 14a of the sprockets 14 in the inner row may be engaged with some of the concave portions 24 among all the concave portions 24 into which the hinge portions 22 and 23 are inserted. In the embodiment, since the engaging recess 47 in which the tooth portion 14 a is engaged is formed in the base portion 21 separately from the recess 44, the tooth portion 14 a is not engaged in the recess 44. For this reason, the restricting portions 45 and 46 may be provided in any recess 44 without being restricted by the tooth portion 14 a without worrying about interference with the tooth portion 14 a of the sprocket 14, and on the inner wall surface of the recess 44. The degree of freedom of its installation position is also high.

  For this reason, as an example in this embodiment, as shown in FIGS. 15 and 16, in the longitudinal direction y of the belt constituent member 40, the position where the restricting portions 45, 46 overlap the engaging recess 47, that is, the sprocket 14. It arrange | positions in the position which overlaps with the tooth | gear part 14a. There is an appropriate interval when the engaging recesses 47 are arranged at two places in the longitudinal direction y of the belt constituent member 40, and also when the restricting portions 45 and 46 are arranged at two places in the longitudinal direction y of the belt constituent member 40. There is a proper interval. Appropriate positions of both are near the center in the longitudinal direction y on both sides of the center position in the longitudinal direction y of the belt constituent member 40. Even if the position of the pair of restricting portions 45 and 46 and the position of the pair of engaging recesses 47 overlap in the longitudinal direction y in securing an appropriate distance between them, in the present embodiment, the pair of restricting portions 45 and 46 The pair of engaging recesses 47 are arranged at appropriate positions overlapping each other in the longitudinal direction y.

  As shown in FIGS. 17, 18, and 20, a rib 48 that extends across the hinge portions 42 and 43 from the base portion 41 in the short direction is provided on the article conveying surface 12 a side of the belt component member 40. However, it extends substantially perpendicularly from the surface (upper surface) opposite to the engagement recess in the thickness direction of the belt constituent member 40 to a certain extension height. That is, the plurality of ribs 48 are arranged at a pitch approximately half the pitch of the hinge portions 42 and 43 in the longitudinal direction of the belt component member 40. The base 41 and the hinge portions 42 and 43 are formed to have substantially the same thickness, and the plurality of ribs 48 have an extension length that is approximately half of these thicknesses from the upper surfaces of the base portion 21 and the hinge portions 42 and 43. Yes.

  The interval between the plurality of ribs 48 is sufficiently shorter than the bottom surface of the article to be conveyed, and the article is conveyed while being supported (placed) on the upper surface of the plurality of ribs 48. As shown in FIGS. 17 and 19, a pair of engaging recesses 47 formed in the base portion 41 at a predetermined interval in the longitudinal direction pass through except for the portions covered with the ribs 48. In addition, a through hole 49 that is narrower in the longitudinal direction than the engaging recess 47 and substantially the same length in the lateral direction is formed in a portion along the longitudinal direction with the engaging recess 47.

Next, the operation of the conveyor belt 12 composed of a plurality of belt constituent members 40 will be described.
The first hinge portion 42 of one belt constituent member 40 and the second hinge portion 43 of the other belt constituent member 40 abut against the restricting portions 45 and 46 that protrude from the bottom surface of the recess 44 between the hinge portions on the other side. In the state where it is inserted all the way to the contact position, the hole 42a of the first hinge part 42 and the hole 43a of the second hinge part 43 coincide with each other to the extent that the pin 30 can be inserted.

  At this time, two restricting portions 45 and 46 provided on one belt constituent member 40 are positions on both sides of the belt constituent member 40 at a predetermined interval across the center position in the longitudinal direction y. In addition, the belt components 40 are provided at positions opposite to each other across the center line in the short direction x. For this reason, when the two belt constituent members 40 are brought close to each other while keeping their postures parallel to each other, both the first hinge part 42 and the second hinge part 43 are inserted into the recesses 44 on the other side. In the longitudinal direction y of the constituent member 40, the hinge portions 42 and 43 and the restricting portions 45 and 46 come into contact with each other at two locations. Therefore, when the two belt constituent members 40, 40 are positioned by contact between the hinge portions 42, 43 and the restricting portions 45, 46, it is avoided that the postures of both are inclined with respect to the counterpart posture. The holes 42a and 43a of all the hinge parts 42 and 43 can be made to coincide.

  For example, when the contact position between the hinge portion and the restricting portion is one place, one belt constituent member is easy to tilt with respect to the other belt constituent member, and the position of the hole is in a part of the hinge portions. Will shift. For this reason, carefulness is required for the operation of aligning the hinge portion by bringing the belt component members close to each other while maintaining a parallel posture. On the other hand, in this embodiment, since the hinge parts 42 and 43 and the control parts 45 and 46 contact | abut at two places and the two belt structural members 40 are positioned, the hinge parts 42 and 43 are set to the control part 45. , 46 is inserted into the recess 44 until it abuts the two belt constituent members 40 at positions where the holes 42a, 43a coincide. Therefore, the workability of the assembly work of connecting the plurality of belt constituent members 40 with the pins 30 is improved. Then, the pin 30 is inserted into the matching holes 42a and 43a.

  The conveyor belt 12 manufactured in this way is wound around the sprocket 14 in a state where the tooth portion 14 a is engaged with the engagement recess 47. At this time, the lower portion of the conveyor belt 12 is supported by the roller 16, and the back bend angle of the portion supported by the roller 16 is the same regardless of the presence or absence of the regulating portion. That is, the restricting portions 45 and 46 are provided at a position on the bottom side of the bottom surface of the concave portion 44, and therefore do not interfere with the back bend of the conveyor belt 12. Therefore, the conveyor belt 12 can bend back at a relatively large angle, and the conveyor belt 12 can be wound along the arc surface of the roller 16. Therefore, the conveyor belt 12 is supported by the roller 16 on the surface, and the pressure that the conveyor belt 12 receives from the roller 16 can be reduced.

As described above in detail, according to the present embodiment, the following effects can be obtained.
(6) Since only two restricting portions 45 and 46 are provided, the number of restricting portions 45 and 46 per belt constituent member 40 can be reduced. In this case, the two restricting portions 45 and 46 are arranged at predetermined intervals on both sides of the belt component member 40 in the longitudinal direction y with the center position therebetween, and the center of the base portion 41 is sandwiched in the short direction x. And are arranged on the inner peripheral surface (for example, the bottom surface) of the recess 44 positioned on the opposite sides. For this reason, the two belt constituent members 40 can be brought into contact with each other at two locations on both sides of the center position in the longitudinal direction y. Therefore, when the hinge portions 42 and 43 are inserted into the concave portion 44 on the other side, it is easy to avoid the posture when the two belt constituent members 40 come into contact with each other, and the positions of all the holes 42a and 43a to be connected are determined. Can be aligned.

  (7) Since the restricting portions 45 and 46 are arranged at positions on the bottom side below the pitch line PL connecting the axes of the holes 42a and 43a (or the pins 30), the same large back bend angle as in the configuration without the restricting portion. Can be secured.

The embodiment may have the following aspects.
In the restricting portions 25 and 26 of the first embodiment, as shown in FIG. 24, the angle θ2 formed between the reference line L and the contacted surfaces 25a and 26a may be an obtuse angle. In this case, as shown in FIG. 25, two adjacent belt constituent members 20 can be back-bended at an obtuse angle. Therefore, the conveyor belt 12 can be bent along the arc surface of the roller 16. Of course, the angle between the contact surfaces 25a and 26a of the restricting portions 25 and 26 and the reference line may be 90 degrees.

  In the first embodiment, the restriction portions are provided on the side surfaces of all the hinge portions 22 and 23. However, for example, the restriction portions may be provided at regular intervals such as every other, every second, every third. Further, the interval at which the restricting portion is provided may be an irregular interval instead of a fixed interval. Even in such a configuration, even when the belt constituent member is cut and used, in most cases, at least two restricting portions remain, so the hinge portion and the restricting portion of the adjacent belt constituent members are positioned in the longitudinal direction y. Can be brought into contact with each other in at least two different places. Further, the restriction portions 25 and 26 may be provided one by one, and the restriction portions 25 and 26 may be arranged at two different positions in the longitudinal direction y of the belt constituent member 20.

  -In 1st and 2nd embodiment, one regulation part may be sufficient per one belt structural member. In this case, it is preferable that one restricting portion be arranged in the central area among the belt constituent members equally divided into three areas in the longitudinal direction y. In particular, the one restricting portion is more preferably a central position in the longitudinal direction y of the belt constituent member. Of course, one restricting portion may be arranged at a position other than the central area.

  -In 1st Embodiment, the to-be-contacted surface of a control part is not limited to linear form (plane shape) like one side of a substantially inverted triangular shape. For example, it is good also as a concave curved surface dented in circular arc surface shape along the circular arc surface outer peripheral surface of the front-end | tip part (annular part 28) of a hinge part.

  -In 1st Embodiment, a control part is not limited to substantially reverse triangle shape. For example, a semicircular shape, a circular shape, an elliptical shape, a trapezoidal shape, or other polygonal shapes may be used. Further, the shape is not limited to a shape that is narrower toward the bottom side of the belt component, and may be a rectangular shape having a constant width in the belt thickness direction or a trapezoidal shape or a triangular shape that becomes wider toward the back side as long as contact with the sprocket can be avoided. . Further, the shape of the restricting portion is not particularly limited as long as a necessary back bend angle can be secured.

-In 2nd Embodiment, the control parts 45 and 46 are not limited to two.
In the second embodiment, the restricting portions 45 and 46 are replaced by plate-like columnar protrusions having a width narrower than the width of the recessed portion 44, and the bottom side portion of the bottom surface of the recessed portion 44 is recessed with the extending direction of the hinge portion. It is good also as a bulging part which bulged with the same width. Moreover, you may provide a control part in the side surface (inner side surface of the recessed part 44) of a hinge part.

  -The position which provides a control part should just be at least one among the side surface (inner side surface of a recessed part) of a hinge part, and the bottom face of a recessed part. For example, a restricting portion provided on the side surface of the hinge portion and a restricting portion provided on the bottom surface of the recess may be mixed in one belt constituent member. Moreover, in one conveyor belt 12, a belt constituent member provided with a restricting portion on the side surface of the hinge portion and a belt constituent member provided with a restricting portion on the bottom surface of the recess may be mixed.

  The position where the restricting portion is provided is not limited to at least one of the side surface of the hinge portion (inner side surface of the concave portion) and the bottom surface of the concave portion, and may be the bottom surface of the hinge portion or the front end surface (outer peripheral surface) of the hinge portion, for example. In addition, in the belt component members adjacent to each other, when the hinge portion is in the posture to be inserted into the recess, a restriction portion is provided at each position facing each other, and the two belt component members are positioned by bringing the respective restriction portions into contact with each other. May be.

  When the restricting portion is a protrusion, the restricting portion is not limited to a plate shape or a column shape, but may be a cylinder shape or a frustum shape such as a truncated cone or a square weight. Further, it may be bent such as L-shaped or T-shaped. Moreover, the structure which provides multiple control parts which contact | abut with one hinge part, and a single hinge part contact | abuts with a some control part, and the position control is carried out in multiple places may be sufficient.
