  By the way, since the processing machine disclosed in Patent Document 1 described above is provided with a large number of pulleys around which a belt ring-shaped body is wound, the configuration of the apparatus is relatively complicated and the apparatus is enlarged. . Further, when the belt ring-shaped body is wound around the processing machine, it is necessary to grip many points on the belt ring-shaped body and set the pulleys on each pulley. Generally, the belt ring-shaped body set in the processing machine has no elasticity because it is not vulcanized, and the belt body can be gripped by gripping a plurality of locations as described above. There is a risk of deformation.

  Moreover, as for the shaping | molding apparatus disclosed by patent document 2 mentioned above, the shaping | molding die in which a belt molded object is formed in an outer peripheral surface is formed in the drum type | mold (column shape). This complicates the apparatus configuration for removing the belt molded body from the mold, and increases the apparatus cost because it is necessary to prepare a mold for each belt circumferential length.

  The present invention is for solving the above-described problems, and an object of the present invention is to provide a molding apparatus for a belt molded body having a compact and general-purpose configuration and capable of suppressing deformation of the belt ring-shaped body during manufacturing. And a method of forming a belt molded body capable of suppressing deformation of the belt ring-shaped body during manufacturing.

That is, one traveling mechanism having a pair of pulleys functions as both a mechanism that travels the belt ring-shaped body when the skive process is performed and a mechanism that travels the belt ring-shaped body when the covering process is performed. Therefore, it is not necessary to provide a traveling mechanism for each process. Thereby, the structure of a shaping | molding apparatus can be simplified. Further, in this configuration, since the belt ring-shaped body can be driven by two pulleys, the molding apparatus can be simplified and miniaturized as compared with the case where the belt ring-shaped body is driven by three or more pulleys. it can.

The belt ring-shaped body before the skive treatment and the covering treatment are in an unvulcanized state, has low elasticity and high adhesiveness. On the other hand, in this configuration, since the pair of pulleys are arranged apart in the vertical direction as described above, for example, a part of the inner peripheral surface of the belt ring-shaped body is gripped and the part is bridged to the upper pulley. As a result, the lower part of the belt ring-like body hangs downward due to its own weight. By setting the position of the lower pulley in advance so that the lower pulley is disposed on the inner peripheral surface side of the portion that hangs downward in this way, the belt ring-shaped body is placed below the lower pulley. The inner peripheral side portion on the lower side can be opposed. That is, according to this configuration, the belt ring-shaped body can be wound around the pair of pulleys only by holding a part of the belt ring-shaped body, so that the deformation of the belt ring-shaped body can be prevented.

In addition, the belt ring-shaped body is configured to be bridged to the upper pulley in a state where the protruding member on which the belt ring-shaped body is hung is in contact with the upper pulley.

  In this configuration, the upper part of the inner peripheral surface of the belt ring-shaped body is supported by the upper side surface of the protruding member. Thereby, the deformation degree of a belt ring-shaped body can be made small compared with the case where a belt ring-shaped body is supported by a dotted | punctate or linear part, for example. Further, in this configuration, the belt ring-shaped body can be bridged from the bridge mechanism to the upper pulley without substantially changing the form of the belt ring-shaped body (particularly, the shape of the upper portion of the belt ring-shaped body). That is, according to this configuration, it is possible to suppress the outflow of defective products due to molding problems.

  (5) More preferably, the pressing portion includes a pressing surface that presses a portion of the belt ring-shaped body that is hung on the upper side surface of the protruding member toward the upper pulley.

  In this configuration, when the belt ring-shaped body is bridged to the upper pulley, the belt ring-shaped body is pressed by the planar portion (pressing surface), so that deformation of the belt ring-shaped body can be prevented.

  (6) More preferably, the pressing surface abuts at least the upper pulley of the protruding member when the pressing surface is relatively displaced toward the belt ring-shaped body hung on the protruding member. Displace to part.

  In this configuration, the skive process can be performed in a state where the shavings cut immediately before are not present in the portion cut by the skive process. That is, according to this configuration, it is possible to suppress the outflow of defective products due to molding problems. Further, in this configuration, since the canvas is pressed against the belt ring-shaped body that travels downward, the canvas is wound around the belt ring-shaped body in a state of extending downward due to its own weight. Thereby, the outflow of the inferior goods resulting from the trouble on shaping | molding can be suppressed.

  (9) Preferably, the apparatus for forming the belt molded body further includes a canvas supply mechanism capable of supplying a plurality of the canvases to the covering processing unit, and each of the canvas supply mechanisms corresponds to each of the canvases.

The belt ring-shaped body 100 is formed in an endless loop shape having a predetermined circumferential length (for example, 60 to 105 inches). The width w of the belt ring-shaped body 100 is, for example, about 13 mm, and the thickness t of the belt ring-shaped body 100 is, for example, about 8 mm.

  The compressed rubber layer 101 is a loop-shaped rubber layer having a predetermined circumferential length, and a cross-sectional shape perpendicular to the longitudinal direction is formed in a rectangular shape as shown in FIG. The compressed rubber layer 101 is made of, for example, natural rubber (NR), styrene butadiene rubber (SBR), chloroprene rubber (CR), or the like. The compression rubber layer 101 is provided as a rubber layer on the inner peripheral side of the belt ring-shaped body 100.

  The stretched rubber layer 103 is a loop-shaped rubber layer having a circumferential length substantially the same as that of the compressed rubber layer 101, and the compressed rubber is sandwiched between the compressed rubber layer 101 and a plurality of core wires 102. The layer 101 is overlaid on the layer 101. The width of the stretched rubber layer 103 is the same as that of the compressed rubber layer 101, while the thickness of the stretched rubber layer 103 is formed to be thinner than that of the compressed rubber layer 101. The stretched rubber layer 103 is configured using, for example, natural rubber (NR), styrene butadiene rubber (SBR), chloroprene rubber (CR), and the like, like the compressed rubber layer 101.

[Configuration of each component constituting the molding apparatus]
[Configuration of belt ring-shaped body supply mechanism]
The belt ring-shaped body supply mechanism 2 includes a suspension mechanism 3 and a transfer mechanism 4. The suspension mechanism 3 is a mechanism for sequentially transferring the plurality of belt-like members 100 one by one to the transfer mechanism 4. Further, the transfer mechanism 4 is a mechanism for sequentially transferring the belt ring-shaped body 100 received from the suspension mechanism 3 to the traveling mechanism 5.

  FIG. 4 is a schematic diagram showing the configuration of the suspension mechanism 3. As shown in FIGS. 3 and 4, the suspension mechanism 3 includes a belt ring-shaped body hanging base 31, a belt ring-shaped body conveyance belt 32, and a gripping mechanism 33.

  The belt ring-shaped body hanging base 31 is a portion formed in an elongated base shape extending in a predetermined direction (left and right direction in the case of FIG. 3), and a plurality of belt ring-shaped bodies 100 are hung along the longitudinal direction. The plurality of belt ring-shaped bodies 100 are hung across a pair of belt ring-shaped body conveyance belts 32 described later by an operator or by automatic conveyance from the previous process.

  The belt ring-shaped body transport belt 32 is provided on each of both ends in the width direction of the belt ring-shaped body hanging base 31, and a plurality of belt ring-shaped bodies 100 hung on the belt ring-shaped body hanging base 31 are arranged in a predetermined direction (in the case of FIG. It is conveyed in the direction of arrow A). Specifically, the belt ring-shaped body conveyance belt 32 intermittently conveys the belt ring-shaped body 100 by a predetermined distance in the arrow A direction. Accordingly, the belt ring-shaped body 100 sequentially picked up by the gripping mechanism 33 can be sequentially sent out to a position where the belt ring-shaped body 100 can be picked up by the gripping mechanism 33.

  Further, the distance between the pair of belt-shaped member transport belts 32 is that the belt ring-shaped member required when the degree of bending of the upper portion of the belt-shaped member 100 hung on the suspension mechanism 3 is hung on the protruding member 43. It is set so that the degree of bending is substantially smaller than the degree of bending of the upper part of 100. In other words, the upper part of the belt ring-shaped body 100 that is hung on the suspension mechanism 3 is less flat and flatter than the upper part of the belt ring-shaped body 100 that is hung on the protruding member 43. It is close. That is, the suspension mechanism 3 also has an action of attaching the belt ring-shaped body 100 in advance so that the shape of the upper portion of the belt ring-shaped body 100 is in a small bending state. Thereby, it becomes easy to bridge the belt ring-shaped body 100 to the protruding member 43, and the outflow of defective products due to molding problems can be suppressed.

  As the belt ring-shaped body conveyance belt 32, it is preferable to use a timing belt in order to ensure feeding accuracy. Moreover, as the belt ring-shaped body conveyance belt 32, it is preferable to use a resin made of urethane or the like in order to prevent the belt ring-shaped body 100 from sticking.

  The gripping mechanism 33 is for picking up the belt ring-shaped body 100 hung on the hanging base 31 and delivering it to the transfer mechanism 4. The gripping mechanism 33 includes a gripping part 34 and a presser part 38.

The upper plate 35 and the lower plate 36 are provided as plate-like portions extending along a horizontal plane. The upper plate 35 is formed with a pair of upper claw portions 35a (only one upper claw portion 35a is shown in FIG. 4) provided in parallel with each other. On the other hand, the lower plate 36 is formed with a pair of lower claw portions 36a (only one lower claw portion 36a is shown in FIG. 4) provided in parallel with each other. Each claw portion 35a, 36a is formed to extend toward the hanging base 31 and the conveyor belt 32 side.

  The lower plate 36 can move in the vertical direction with respect to the upper plate 35 by an air cylinder (not shown). Thereby, although mentioned later in detail, grip part 34 can hold belt ring-shaped object 100 on both sides of upper claw part 35a and lower claw part 36a.

  The grip portion 34 is configured to be slidable along an LM guide (not shown) extending in parallel with the hanging base 31. The gripping part 34 can be advanced along the LM guide to the platform 31 side (Bf direction in FIG. 3) and retracted away from the platform 31 (Bb direction in FIG. 3) by a linear actuator (not shown). Is possible.

  FIG. 5 is a view of FIG. 4 as viewed from the direction of the arrow V and is a view for explaining a schematic shape of the presser portion 38. The presser portion 38 is disposed above the mount 31 and can be moved up and down by an air cylinder (not shown) or the like. The presser portion 38 is one before the belt ring-shaped body 100 (that is, the belt ring-shaped body 100 picked up next by the gripping mechanism 33) located on the most distal side (the right side in FIGS. 3 and 4) of the hanging base 31. This is for pressing the belt belt-like body 100 on the side from the upper side. As a result, when the belt ring-shaped body 100 is picked up by the gripping portion 34, the belt ring-shaped body 100 adjacent thereto is accidentally caught and dropped from the hanging base 31, or the two belt ring-shaped bodies 100 are gripped at a time. Can be prevented. That is, by providing the presser portion 38, even if a plurality of belt ring-shaped bodies 100 are arranged on the hanging base 31 without gaps, the belt ring-shaped bodies 100 can be reliably picked up one by one.

  And the press part 38 has a pair of acute angle | corner front-end | tip parts 38a which protrude in an acute angle shape downward as shown in FIG. In the presser portion 38, each acute angle distal end portion 38 a presses each of the portion of the belt ring-shaped body 100 that is placed on the one conveyance belt 32 and the portion that is placed on the other conveyance belt 32. Thereby, since the belt ring-shaped body 100 is not pressed by the planar portion but is pressed by the dot-shaped portion, it is possible to prevent the belt ring-shaped body from sticking to the pressing portion 38.

[Belt ring pick-up operation by gripping part]
6A and 6B are diagrams for explaining the operation of the suspension mechanism 3, in which FIG. 6A is a diagram illustrating a state in which the gripping portion 34 advances toward the hanging base 31, and FIG.

  The suspension mechanism 3 operates as follows with reference to FIG. Specifically, in the suspension mechanism 3, the gripping portion 34 moves in the advance direction Bf (see FIG. 6A) and stops near the hanging base 31 (see FIG. 6B). When this operation is performed, the belt ring-shaped body 100 that is one before the belt ring-shaped body 100 to be picked up next is pressed by the pressing portion 38.

  Next, the lower plate 36 of the grip part 34 is raised. Thereby, the belt ring-shaped body 100 located on the most distal end side (right side in FIG. 6) of the hanging base 31 is sandwiched and held by the upper claw portion 35a and the lower claw portion 36a (see FIG. 6C). . Thereafter, in the gripping mechanism 33, the gripping portion 34 is retracted in the retracting direction Bb, and the presser portion 38 is raised. Then, although the illustration is omitted after the presser portion 38 is lifted, the belt-shaped member 100 that is gripped by the gripping portion 34 next is transported to the front end portion of the hanging base 31 by driving the transport belt 32. . Thereafter, the belt ring-shaped body 100 that is one before the belt ring-shaped body 100 to be picked up next is pressed by the presser 38, and the state returns to the state of FIG.

Specifically, the linear motion mechanism 24 has the above-described standby position P2 and a transfer position P3 that is a position where the belt main body 40 is moved to the travel mechanism 5 side and the belt ring-shaped body 100 is transferred to the travel mechanism 5. And the gantry body part 40 is moved directly between.

[Delivery operation of belt ring-shaped body from gripping part to crossover body]
FIG. 10 is a diagram for explaining a state when the belt-shaped member 100 gripped by the gripping part 34 is delivered to the gantry main body 40, and (A) is a diagram showing a state before delivery; (B) is a figure which shows the state after delivery. In addition, in FIG. 10, about the holding | grip part 34, only a pair of upper claw part 35a and a pair of lower claw part 36a are shown in figure.

  When the belt ring-shaped body 100 is transferred from the gripping part 34 to the gantry main body 40, the gripping part 34 in the state of gripping the belt ring-shaped body 100 is in a state of being retracted in the retracting direction Bb. On the other hand, the transfer main body 40 is turned by the turning mechanism 23 and is located at the receiving position P1. In this state, the gripping portion 34 and the crossing main body portion 40 face each other (refer to FIG. 27 described later in detail).

  As described above, after the gripping portion 34 and the crossing main body portion 40 face each other, the gripping portion 34 advances toward the advance direction Bf. Then, the belt ring-shaped body 100 sandwiched and held by the upper claw portion 35a and the lower claw portion 36a in the gripping portion 34 is positioned above the protruding member 43 in the crossing main body portion 40 (FIG. 10 ( A)). Thereafter, when the pair of lower claw portions 36a are lowered, the belt ring-shaped body 100 supported by the lower claw portions 36a is dropped and is caught by the upper side surface 43a of the protruding member 43 (FIG. 10 ( B)). At this time, each lower claw portion 36 a enters each notch 44 a of the protruding member 43, so that interference between the lower claw portion 36 a and the protruding member 43 can be avoided.

[Configuration of traveling mechanism]
FIG. 11 is a schematic diagram illustrating a schematic configuration of the traveling mechanism 5. As shown in FIG. 11, the traveling mechanism 5 includes an upper pulley 51 and a lower pulley 55, and an air cylinder (not shown) for raising and lowering the lower pulley 55. The upper pulley 51 and the lower pulley 55 are arranged so as to be separated in the vertical vertical direction. The upper pulley 51 is disposed above the lower pulley 55. A rotation shaft of an electric motor (not shown) is connected to the center portion of the upper pulley 51. On the other hand, the lower pulley 55 is provided to be rotatable about the central axis of the lower pulley 55.

  12A and 12B are diagrams showing the shape of the upper pulley 51, where FIG. 12A is a plan view and FIG. 12B is a side view. The upper pulley 51 has a pulley body 52 and a pair of flanges 53, which are integrally provided.

  The pulley main body 52 is a portion formed in a disk shape having a predetermined thickness, and is provided as a portion around which the belt ring-shaped body 100 is wound. The axial thickness of the pulley main body 52 is substantially the same as the length of the width w of the belt ring-shaped body 100. Further, a plurality of groove portions 52 a extending along the axial direction of the pulley main body portion 52 are formed on the outer peripheral surface of the pulley main body portion 52. A plurality of the groove portions 52 a are formed along the circumferential direction of the outer peripheral surface of the pulley main body portion 52. This prevents slipping of the belt ring-shaped body 100 with respect to the upper pulley 51 during travel of the belt ring-shaped body 100 (when the upper pulley 51 is rotationally driven).

  Each flange 53 is a disk-shaped portion provided on both axial ends of the upper pulley 51. The flange portion 53 is provided coaxially with the pulley main body portion 52. The outer diameter of the flange 53 is larger than the outer diameter of the pulley main body 52. Thereby, it is possible to prevent the belt ring-shaped body 100 from being detached from the upper pulley 51 in a state where the belt ring-shaped body 100 is wound around the pulley main body portion 52. Moreover, the outer diameter of the collar part 53 is the same as the outer diameter of the protrusion member 43, or is a little (for example, about 1 mm). The height h of each flange 53 is set to be lower than the thickness t of the belt ring-shaped body 100. Specifically, the height h is set to be approximately half of the thickness of the compressed rubber layer 101 (see FIG. 1) of the belt ring-shaped body 100. A tapered surface that gradually decreases from the outer side to the inner side in the thickness direction of the flange 53 is formed on the radially outer portion of each flange 53. Thereby, the belt ring-shaped body 100 can be smoothly transferred from the transfer main body 40 to the upper pulley 51.

  Referring to FIG. 11, the lower pulley 55 has a pulley main body portion 56 and a flange portion 57, and these are integrally provided. The pulley main body portion 56 is a portion formed in a columnar shape, and is provided as a portion around which the belt ring-shaped body 100 is wound. The lower pulley 55 can move up and down.

  The outer diameter of the pulley body 56 of the lower pulley 55 is equal to the outer diameter of the pulley body 52 of the upper pulley 51. The flange portion 57 is provided on the back side of the pulley main body portion 56 (on the opposite side of the pulley main body portion 56 in the axial direction of the pulley main body portion 40). The flange portion 57 is provided coaxially with the pulley main body portion 56. The outer diameter of the flange portion 57 is larger than the outer diameter of the pulley main body portion 52. Thereby, it is possible to prevent the belt ring-shaped body 100 from being detached to the back side of the lower pulley 55 when the traveling mechanism 5 is traveling.

  In the traveling mechanism 5, the belt annular body 100 is wound around the pair of pulleys 51 and 55 as will be described in detail later, and then the electric motor connected to the upper pulley 51 is rotationally driven to rotate the belt annular body 100. Runs so as to circulate between the pair of pulleys 51 and 55. Then, a skive process and a covering process, which will be described in detail later, are performed on the belt ring-shaped body 100 traveling in this way.

[Transfer operation of the belt ring-shaped body from the main body to the upper pulley]
13 and 14 are diagrams illustrating a process in which the belt-shaped member 100 is bridged from the bridge body 40 to the upper pulley 51. FIG. Specifically, FIG. 13 (A) is a diagram showing a state in which the gantry main body 40 on which the belt ring-shaped body 100 is hung is close to the upper pulley 51, and FIG. 13 (B) is a gantry main body. FIG. 14A is a view showing a state in which the 40 protruding members 43 are in contact with the upper pulley 51, FIG. 14A is a view showing a state in which the support member 42 is in contact with the belt ring-shaped body 100, and FIG. It is a figure which shows the state in which the annular body 100 was spanned on the upper pulley 51. FIG.

  The belt ring-shaped body 100 hung on the protruding member 43 of the gantry main body 40 is wound around the traveling mechanism 5 as follows. Specifically, the gantry body 40 that has received the belt ring-shaped body 100 at the receiving position P1 is turned to the standby position P2 by the turning mechanism 23. As a result, the gantry main body 40 and the upper pulley 51 face each other (see FIG. 28 described later in detail).

  When the linear motion mechanism 24 is driven in this state, the transfer main body 40 gradually advances toward the upper pulley 51 (in the direction of the white arrow in FIG. 13A), and the circle of the protruding member 43 The plate portion 44 comes into contact with the front flange portion 53 of the upper pulley 51 (see FIG. 13B). Since the central axis of the protruding member 43 is set to be coaxial with the central axis of the upper pulley 51, in the state shown in FIG. 13B, the disk portion 44 and the flange portion 53 of the protruding member 43 Will be in a state of exactly overlapping. Note that the central axis of the protruding member 43 may be set slightly above the central axis of the upper pulley 51 (for example, about 0.5 mm as an example).

  Further, when the linear motion mechanism 24 is driven, the protruding member 43 is maintained at the position as it is, while the support member 42 moves forward against the urging force of the coil spring 47. Thereby, the front end surface 42b (pressing surface) of the support member 42 contacts the belt ring-shaped body 100 hung on the protruding member 43 (see FIG. 14A). Then, the support member 42 is further advanced, and the front end surface 42b thereof is slightly beyond the surface in contact with the flange portion 53 of the protruding member 43, specifically, the back surface of the front flange portion 53. And move to the same position. As a result, the belt ring-shaped body 100 gets over the front flange 53 and fits between the pair of flanges 53 (see FIG. 14B), and is wound around the upper pulley 51. In this state, as shown in FIG. 15A, the lower pulley 55 is in a raised state, and therefore the belt ring-shaped body 100 is wound only on the upper pulley 51.

  FIG. 15 is a diagram illustrating a process in which the belt ring-shaped body 100 laid around the upper pulley 51 is wound around both the upper pulley 51 and the lower pulley 55. Specifically, FIG. 15A is a diagram showing a state immediately after the belt ring-shaped body 100 is bridged over the upper pulley 51, and FIG. 15B is a diagram illustrating the lower pulley 55 being lowered and both pulleys. FIG. 5 is a view showing a state in which a belt ring-shaped body 100 is wound around 51 and 55;

  When the belt ring-shaped body 100 is stretched over the upper pulley 51, the lower pulley 55 is lowered by the air cylinder. Thereby, the belt ring-shaped body 100 is wound around the lower surface of the pulley body 56 of the lower pulley 55 (see FIG. 15B). Further, since the belt ring-shaped body 100 is pulled in the vertical direction by the upper pulley 51 and the lower pulley 55, an appropriate tension is applied to the belt ring-shaped body 100.

  In addition, when the lower pulley 55 descends as described above, the gantry main body 40 remains in the vicinity of the traveling mechanism 5. That is, when the lower pulley 55 is lowered, the belt-like member 100 that is hung on the upper pulley 51 is covered by the flat plate portion 22 (see FIG. 7) so as not to protrude toward the front side. Thereby, the belt ring-shaped body 100 can be reliably wound around the lower pulley 55. In the traveling mechanism 5, after the belt ring-shaped body 100 is wound around the pair of pulleys 51 and 55 in FIG. 15B, the upper pulley 51 is rotated by the electric motor, so that the belt ring-shaped body 100 is paired. It travels so that it may circulate between pulleys 51 and 51. In the present embodiment, the upper pulley 51 is rotationally driven in the clockwise direction when the traveling mechanism 5 is viewed from the front side. As a result, the right part of the belt ring-shaped body 100 set in the traveling mechanism 5 travels downward, while the left part travels upward.

[Configuration of skive processing section]
FIG. 16 is a diagram illustrating a schematic configuration of the skive processing unit 6, and is a diagram illustrating the belt ring-shaped body 100 in a state in which skive processing is performed by the skive processing unit 6.

By doing so, the cross-sectional shape of the belt ring-shaped body 100 is made to be substantially trapezoidal. The skive processing unit 6 includes a skive processing main body 61 and a skive adjusting mechanism 65.

  The skive processing main body 61 has a pair of skive cutters 62. Each skive cutter 62 is formed in a substantially cylindrical shape whose central axis extends in the vertical direction. The skive cutter 62 can be displaced between a standby position P4 and a skive position P5 shown in FIG. 17 by a displacement mechanism (not shown). The skive cutter 62 is located at the standby position P4 while the skive process is not being performed. On the other hand, the skive cutter 62 moves from the standby position P4 to the skive position P5 when the skive process is performed. At this time, the outer peripheral edge of the skive cutter 62 comes into contact with the corner portion 101 a of the belt ring-shaped body 100. In this state, when the traveling mechanism 5 is driven and the belt ring-shaped body 100 travels, the corner portion 101a is cut off.

  As shown in FIGS. 16 and 17, the skive cutter 62 is a portion that travels from the upper side to the lower side of the belt ring-shaped body 100 that circulates between the pair of pulleys 51 and 55 (in FIGS. 16 and 17). Abut on the right part). Thereby, the shavings excised by the skive cutter 62 fall downward due to gravity. The shavings that have fallen downward in this way are discharged by a scrap discharge duct (not shown) provided slightly below the portion where the belt ring-shaped body 100 is cut by the skive cutter 62.

  The skive adjusting mechanism 65 has a back pushing roll 66 and a pair of guide rolls 67. The back pushing roll 66 is provided to be rotatable around a central axis extending in parallel with the central axes of the pulleys 51 and 55 of the traveling mechanism 5. The pair of guide rolls 67 are arranged along the width direction of the belt ring-shaped body 100 (vertical direction in FIG. 17) so that the gap is slightly wider than the width w of the belt ring-shaped body 100 (see FIG. 1). Yes.

  The skive adjusting mechanism 65 can be displaced between a standby position P6 and a skive adjusting position P7 shown in FIG. 17 by, for example, an air cylinder (not shown). The skive adjusting mechanism 65 is located at the standby position P6 while the skive process is not being performed. On the other hand, the skive adjustment mechanism 65 moves from the standby position P6 to the skive adjustment position P7 when the skive process is performed. At this time, the back surface of the belt ring-shaped body 100 (the portion on the elongated rubber layer 103 side) is pushed into the skive cutter 62 side by the back pushing roll 66, so that the corner 101 a of the belt ring-shaped body 100 contacts the outer peripheral edge of the skive cutter 62. Can be touched. And the range of the corner | angular part 101a to be excised can be adjusted by adjusting the pushing amount of the belt ring-shaped body 100 by the back pushing roll 66. FIG.

  When the skive adjusting mechanism 65 moves from the standby position P6 to the skive adjusting position P7 as described above, the belt ring-shaped body 100 is guided between the pair of skive cutters 62 by the pair of guide rolls 67. Thereby, the belt ring-shaped body 100 can be reliably passed between the pair of skive cutters 62.

[Configuration of canvas supply mechanism]

[Operation of the cover processing unit]
In the covering processing unit 8, the constituent elements of the covering processing unit 8 operate as follows, so that the lower cover 106 and the upper cover 107 are attached to the belt ring-shaped body 100 that has been subjected to skive processing. On the other hand, it is wound sequentially.

  In a state before the covering process by the covering process unit 8 is performed, the pressing roll 81, the catcher unit 82, and the bottom-side bent disc 88 are respectively in a standby position P8, with reference to FIGS. 19 and 20. Waiting at P10 and P12. When the covering process is performed, the lower cover tip gripping portion 74 a that grips the tip of the lower cover 106 moves to the vicinity of the upper end of the upper pulley 51 by the cover gripping portion displacement mechanism 79. As a result, the tip of the lower cover 106 is in close contact with the belt ring-shaped body 100. On the other hand, the pressing roll 81, the catcher portion 82, and the bottom-side bent disk 88 are moved from the standby positions P8, P10, P12 to the covering processing positions P9, P11, P13 by a displacement mechanism (not shown) thereafter or in parallel therewith. Move up. As a result, the tip of the lower cover 106 in close contact with the belt ring-shaped body 100 is pressed by the pressing roll 81. Thereafter, the lower cover tip gripping portion 74a releases the grip on the lower cover 106 and retracts backward.

  In the state as described above, since the upper pulley 51 is rotationally driven by the electric motor, the front end portion of the lower cover 106 is sequentially sent out downward. The front end portion of the lower cover 106 is first squeezed by a squeeze roll 83 so that the cross-sectional shape is substantially U-shaped, and then travels further downward. The belt is wound around the outer peripheral surface of the belt ring-shaped body 100 by the back roller 85 and the bottom-side bent disk 88. Note that when the side-side bending rolls 84 are pressed against the side surfaces of the belt ring-shaped body 100 at both ends in the width direction of the lower cover 106, the center portion in the width direction of the lower cover 106 is pressed by the back roller 85. The winding wrinkles of the lower cover 106 can be effectively suppressed.

  Then, immediately before the lower cover 106 is wound around the entire outer peripheral surface of the belt ring-shaped body 100, the upper pulley 51 temporarily stops while decelerating. Next, after the lower cover 106 is gripped by the lower cover tip gripping portion 74a, a portion closer to the belt ring-shaped body 100 than the gripped portion is cut by scissors (not shown). Thereafter, the upper pulley 51 is rotationally driven again, and the remaining lower cover 106 is wound around the belt ring-shaped body 100, whereby the winding of the lower cover 106 around the belt ring-shaped body 100 is completed.

  Next, the upper cover 107 is wound by the covering processing unit 8. Specifically, first, after the position of the lower cover tip gripping portion 74a and the position of the upper cover tip gripping portion 78a are switched by the cover gripping portion displacement mechanism 79, the tip end portion of the upper cover 107 is gripped. The upper cover tip gripping portion 78 a is moved to the vicinity of the upper end portion of the upper pulley 51 by the cover gripping portion displacement mechanism 79. As a result, the tip of the upper cover 107 comes into close contact with the lower cover 106 wound around the belt ring-shaped body 100. On the other hand, thereafter, or in parallel therewith, after the winding of the lower cover 106 is completed, the pressing roll 81 and the catcher portion 82 that have once retracted to the standby positions P8 and P10 move again to the covering processing positions P9 and P11. As a result, the tip of the upper cover 107 in a state of being in close contact with the lower cover 106 wound around the belt ring-shaped body 100 is pressed by the pressing roll 81. Thereafter, the upper cover tip gripping portion 78a releases the grip on the upper cover 107 and retracts backward.

  Thereafter, the upper cover 107 is wound around the belt ring-shaped body 100 in the same manner as the case of the lower cover 106 described above. Thereby, the belt molded body 105 having the shape shown in FIG. 2 is completed.

If it does so, it will be in the state where the belt ring-shaped body 100 supported by the lower side claw part 36a fell, and was hooked on the upper side of the protrusion member 43. FIG. Thereby, the belt ring-shaped body 100 is bridged from the gripping part 34 to the bridge body part 40 (see FIG. 10B).

  Next, in step S <b> 4, the belt ring-shaped body 100 is transferred from the transfer main body 40 to the traveling mechanism 5. Specifically, first, after the gripping part 34 that has laid the belt ring-shaped body 100 to the laying body part 40 in step S3 has moved to the retracting direction Bb side, the linking body part 40 has moved to the standby position P2. (Refer to FIG. 28), and further move to the transfer position P3 (see FIG. 9). Accordingly, as shown in FIGS. 13 and 14, the belt ring-shaped body 100 is bridged from the bridge body 40 to the upper pulley 51. The transfer main body 40 moves the belt ring-shaped body 100 to the upper pulley 51 and then moves to the standby position P2 again (see FIG. 29).

  In this embodiment, as described above, after the transfer main body 40 moves to the transfer position P3, the gripping part 34 moves to the belt ring-shaped body hanging base 31, and the next belt ring-shaped body 100 is gripped. The robot moves again in the retracting direction Bb, and then waits at that position until the belt ring-shaped body 100 is bridged over the bridge body 40 (see FIG. 28).

  In step S4, next, referring to FIG. 15, the lower pulley 55 moves downward (see FIG. 15B). As a result, the belt ring-shaped body is wound around the pair of pulleys 51 and 55 in the traveling mechanism 5 and an appropriate tension is applied.

  Next, in step S5, skive processing by the skive processing unit 6 is performed. Specifically, in step S5, with reference to FIGS. 16 and 17, the pair of skive cutters 62 moves from the standby position P4 to the skive position P5 with respect to the belt-shaped ring body 100 traveling by the rotational drive of the upper pulley 51. In addition to the displacement, the skive adjusting mechanism 65 is displaced from the standby position P6 to the skive adjusting position P7. Thereby, the skive process in which the corner | angular part of the belt ring-shaped body 100 is excised is performed.

  Next, in steps S6 and S7, a covering process is performed by the canvas supply mechanism 7 and the covering processing unit 8. Specifically, in step S6, the lower cover 106 is wound around the belt ring-shaped body 100 on which the skive process has been performed. In step S <b> 7, the upper cover 107 is wound around the outer side of the lower cover 106 wound around the belt ring-shaped body 100 in step S <b> 6.

  First, in step S6, referring to FIG. 19 to FIG. 21, the lower cover tip gripping portion 74a of the canvas supply mechanism 7 moves the tip portion of the lower cover 106 near the upper end portion of the upper pulley 51 by the cover gripping portion displacement mechanism 79. Move up. On the other hand, the pressing roll 81, the catcher portion 82, and the bottom-side bent disk 88 are moved from the standby positions P8, P10, P12 to the covering processing positions P9, P11, P13 by a displacement mechanism (not shown) thereafter or in parallel therewith. Move up. Thereby, each component 81, 82, 88 for performing the process for winding the lower cover 106 around the belt ring-shaped body 100 is disposed at a predetermined position.

  In step S6, after the lower cover tip gripping portion 74a releases the grip on the lower cover 106 and retracts backward, the upper pulley 51 is driven to rotate, whereby the lower cover 106 is placed on the outer peripheral surface of the belt ring-shaped body 100. Wrapped. After the winding of the lower cover 106 is completed in this way, the pressing roll 81 and the catcher unit 82 are temporarily retracted from the covering processing positions P9 and P11 to the standby positions P8 and P10, and the rotational driving of the upper pulley 51 is once performed. Stopped.

  Next, in step S <b> 7, the upper cover tip gripping portion 78 a of the canvas supply mechanism 7 moves the tip portion of the upper cover 107 to the vicinity of the upper end portion of the upper pulley 51 by the cover gripping portion displacement mechanism 79. On the other hand, after that or in parallel therewith, the pressing roll 81 and the catcher portion 82 move again to the covering processing positions P9 and P11. Thereby, each component 81,82,88 for performing the process for winding the upper cover 107 around the belt ring-shaped body 100 is arrange | positioned in a predetermined position.

  In step S7, the upper cover tip gripping portion 78a releases the grip on the upper cover 107, retracts backward, and then the upper pulley 51 is driven to rotate, whereby the lower cover 106 wound around the belt ring-shaped body 100 is driven. The upper cover 107 is wound around the outer side of the belt, thereby completing the belt molded body 105.

  In the present embodiment, while the above-described steps S5 to S7 are performed, the transfer main body 40 moves to the receiving position P1, and the belt 34 from the gripping portion 34 that has already gripped the next belt ring-shaped body 100. The ring-shaped body 100 is received (see FIG. 30). Furthermore, in the present embodiment, the arm portion 94 of the removal mechanism 9 moves from the standby position P14 to the advanced position P15 while steps S6 and S7 are being performed (see FIG. 30).

  Finally, in step S <b> 8, the belt molded body 105 is removed from the traveling mechanism 5 and is hung on the belt molded body hanging base 98. Specifically, in step S8, referring to FIG. 23 and FIG. 24, the belt molded body 105 released from being held by the pair of pulleys 51 and 55 as the lower pulley 55 is lifted is pushed forward by the discharge bar. Then, it falls downward and is caught by a pair of arm claws 95 formed on the arm 94. Thereafter, when the arm portion 94 returns to the standby position P <b> 16, the belt molded body 105 held by the arm portion 94 is caught by the horizontal bar 96 and falls downward, and is caught by the left portion of the belt molded body hanging base 98. Thereby, the belt molded body 105 can be removed from the traveling mechanism 5. Thereafter, the belt molded body 105 is conveyed to the right side by the belt molded body conveyance belt 99. Thereby, in the belt molded body conveyance belt 99, a place where the belt molded body 105 to be molded next is hung can be made empty (see FIG. 31).

  Then, from the state shown in FIG. 31, the transfer main body 40 in the state where the belt ring-shaped body 100 to be subjected to the skive process and the covering process is already applied is the same as in the case of step S4 described above. To the transfer position P3, and the belt ring-shaped body 100 is transferred to the upper pulley 51.

  Thereafter, the steps described above are sequentially repeated. Thereby, in the shaping | molding apparatus 1 which concerns on this embodiment, the some belt molded object 105 can be shape | molded automatically sequentially.

[effect]
As described above, in the molding apparatus 1 for the belt molded body 105 according to the embodiment, the pair of pulleys 51 and 55 (the upper pulley 51 and the lower pulley 55) are wound around the pair of pulleys 51 and 55. A skive process and a covering process are performed on the belt-shaped annular body 100 traveling in the above manner. That is, one traveling mechanism 5 having a pair of pulleys 51 and 55 causes the belt annular body 100 to travel when the skive process is performed, and the mechanism causes the belt annular body 100 to travel when the covering process is performed. Therefore, it is not necessary to provide a traveling mechanism for each process. Thereby, the structure of the shaping | molding apparatus 1 can be simplified. Further, in the molding apparatus 1, since the belt ring-shaped body 100 can be driven by the two pulleys 51 and 55, the molding apparatus can be simplified and compared with the case where the belt ring-shaped body 100 is driven by three or more pulleys. Miniaturization can be achieved.

  And according to the shaping | molding apparatus 1, the upper side pulley 51 and the lower side pulley 55 around which the belt ring-shaped body 100 is wound are arrange | positioned away in the up-down direction. The belt ring-shaped body 100 before the skive process and the covering process are performed is in an unvulcanized state and thus has low elasticity and high adhesiveness. On the other hand, in the molding apparatus 1, since the pair of pulleys 51 and 55 are arranged apart in the vertical direction as described above, for example, a part of the inner peripheral surface of the belt ring-shaped body 100 is gripped, and the part is By spanning the upper pulley 51, the lower portion of the belt ring-shaped body 100 hangs downward due to its own weight. By setting the position of the lower pulley 55 in advance so that the lower pulley 55 is disposed on the inner peripheral surface side of the portion that hangs downward in this manner, the belt is placed below the lower pulley 55. The inner peripheral side portion on the lower side of the ring-shaped body 100 can be opposed. That is, according to the molding apparatus 1, the belt ring-shaped body 100 can be wound around the pair of pulleys 51 and 55 by only holding a part of the belt ring-shaped body 100. Can be prevented.

  Therefore, the molding apparatus 1 can provide a molding apparatus for a belt molded body that has a compact and general-purpose configuration and can suppress deformation of the belt ring-shaped body 100 during manufacturing.

  Further, in the molding apparatus 1, after the belt ring-shaped body 100 is supplied to the traveling mechanism 5 by the belt ring-shaped body supply mechanism 2, the skiving process and the covering process are automatically performed on the belt ring-shaped body 100 traveling by the traveling mechanism 5. As a result, the belt molded body 105 is molded. The belt molded body 105 formed in this manner is automatically detached from the traveling mechanism 5 by the removal mechanism 9. As a result, the belt ring-shaped body 100 to be subjected to the skive process and the covering process next can be set to the traveling mechanism 5 by the belt ring-shaped body supply mechanism 2. In other words, according to this configuration, a plurality of belt molded bodies can be formed fully automatically without intervention of the operator.

  In the molding apparatus 1, the upper part of the inner peripheral surface of the belt ring-shaped body 100 is supported by the upper side surface 43 a of the protruding member 43. Thereby, the deformation degree of the belt ring-shaped body 100 can be reduced as compared with the case where the belt ring-shaped body 100 is supported by, for example, a dotted or linear portion. In the molding apparatus 1, the belt ring-shaped body 100 is hung from the transfer mechanism 4 to the upper pulley 51 without substantially changing the form of the belt ring-shaped body 100 (particularly, the shape of the upper portion of the belt ring-shaped body 100). Can pass. That is, according to the shaping | molding apparatus 1, the outflow of inferior goods resulting from the trouble on shaping | molding can be suppressed.

  Further, in the molding apparatus 1, the belt ring-shaped body 100 can be bridged to the upper pulley 51 in a state where the protruding member 43 with the belt ring-shaped body 100 hung on the upper side surface 43 a is in close contact with the upper pulley 51. The ring-shaped body 100 can be reliably transferred to the upper pulley 51.

  Moreover, in the shaping | molding apparatus 1, both the function which supports the protrusion member 43 by one member (support member 42), and the function which presses the belt ring-shaped body 100 hung on the protrusion member 43 to the upper pulley 51 side. Can be fulfilled. Thereby, the apparatus can be made compact.

  Further, in the molding apparatus 1, when the belt ring-shaped body 100 is bridged to the upper pulley 51, the belt ring-shaped body 100 is pressed by the planar portion (the front end surface 42b as the pressing surface), so that deformation of the belt ring-shaped body 100 is prevented. Can do.

  Further, in the molding apparatus 1, all portions of the belt ring-shaped body 100 that are hung on the protruding member 43 can be moved from the protruding member 43 to the upper pulley 51. As a result, the belt ring-shaped body 100 can be reliably transferred to the upper pulley 51.

  Further, in the molding apparatus 1, after the belt ring-shaped body 100 is bridged from the protruding member 43 to the upper pulley 51, the protruding member 43 is subjected to the skive process and the covering process for the belt ring-shaped body 100. Next, the belt ring-shaped body 100 to be subjected to the skive process and the covering process can be hung. In other words, according to the molding apparatus 1, steps necessary for molding the belt molded body 105 can be performed in parallel, so that work efficiency can be improved.

  In the molding apparatus 1, the skive process is performed on the portion of the belt ring-shaped body 100 that is traveled by the travel mechanism 5 that travels from the upper side to the lower side. In this way, the skive process can be performed in a state where the shavings cut immediately before are not present in the portion cut by the skive process. That is, according to the shaping | molding apparatus 1, the outflow of inferior goods resulting from the trouble on shaping | molding can be suppressed. In the molding apparatus 1, the covers 106 and 107 are pressed against the belt ring-shaped body 100 traveling downward, so that the covers 106 and 107 are wound around the belt ring-shaped body 100 in a state of extending downward due to their own weight. Thereby, the outflow of the inferior goods resulting from the trouble on shaping | molding can be suppressed.

  In the molding apparatus 1, the plurality of canvases (the lower cover 106 and the upper cover 107) can be continuously and automatically wound around the belt ring-shaped body 100. That is, according to the molding apparatus 1, manual work is not required when the plurality of covers 106 and 107 are wound, so that outflow of defective products due to molding problems can be suppressed. Moreover, according to the shaping | molding apparatus 1, since it becomes unnecessary to provide the traveling mechanism corresponding to each cover in order to wind a some cover around a belt ring-shaped body, an apparatus can be simplified.

  In addition, according to the method for forming the belt molded body 105 by the molding apparatus 1 described above, it is possible to provide a method for molding a belt molded body that can suppress deformation of the belt ring-shaped body 100 during manufacturing.

(2) In the above-described embodiment, the depth d ₄₂ of the support member 42 is set to be the sum of the height h ₄₃ of the protruding member ₄₃ and the thickness t ₅₃ of the flange portion 53. Not exclusively. Specifically, the depth d ₄₂ of the support member 42 may be set to be equal to the height h ₄₃ of the protruding member 43.

  (3) In the above-described embodiment, the skive process and the covering process for the belt ring-shaped body 100 are performed on the same side (the right side in FIGS. 16 and 19, the side on which the belt ring-shaped body 100 travels downward). However, not limited to this, one may be performed on the right side and the other on the left side. In this case, a bidirectionally rotatable motor is used as the electric motor for driving the upper pulley 51 so that each process is performed on the belt ring-shaped body 100 that travels downward during skiving and covering. Is better.

  (4) In the above-described embodiment, the molding apparatus 1 is configured so that the plurality of belt molded bodies 105 can be manufactured fully automatically. However, the present invention is not limited to this. Specifically, for example, the belt ring-shaped body supply mechanism 2 and the removal mechanism 9 may be omitted. Thereby, although the work process by the worker increases (set of the belt ring-shaped body with respect to the traveling device and removal of the belt molded body from the traveling device), it has a compact and general-purpose configuration as in the above-described embodiment. In addition, it is possible to provide a belt molded body forming apparatus capable of suppressing deformation of the belt ring-shaped body 100 during manufacturing.

  The present invention relates to a belt molded body molding apparatus and a belt molded body molding method, and more particularly, to molding a wrapped V belt in which a surface of a belt ring-shaped body formed so as to have a V-shaped cross section is covered with a canvas. The present invention can be widely applied to a body molding apparatus and a molding method thereof.
