Definitions
- the present invention relates to an apparatus, an assembling method, and a manufacturing method for assembling a belt constituted by arranging a large number of plate-like elements in an annular shape with their directions aligned, and bundling these elements by a ring. .
- This type of belt is configured to transmit torque by the pressing force between the metal pieces arranged in contact with each other, and the metal piece sandwiched in the winding groove in the pulley on the driving side, By rotating the pulley, the pulley is sequentially pushed out from the winding groove to press the preceding metal piece. As the metal piece thus advanced enters the winding groove in the driven pulley, torque is transmitted to the driven pulley as the metal piece advances.
- FIG. 10 shows the shape of the block 100.
- the block 100 shown here is annularly arranged so that the short side is the inner peripheral side.
- the left and right side portions 101 and 102 in the arrangement state are inclined corresponding to the tapered inner surface of the V-shaped winding groove in the pulley (not shown).
- a saddle surface 104 around which the endless carrier 103 is wound is formed at substantially the center in the vertical direction and the width direction.
- the saddle surface 104 is formed to have a width equal to or larger than the width of the two endless carriers 103 arranged side by side in the width direction.

- the interval between the locking portions that is, the width of the opening is narrower than the width of the entire endless carrier in a state where the blocks are bound. Therefore, when the endless carrier and the block are assembled to each other, if the endless carrier and the block are arranged at the same relative positions as after the completion of the assembly, the endless carrier cannot pass through the opening in the block, so that they cannot be assembled to each other. . For this reason, it is necessary to devise some means to assemble the blocks on the endless carrier. However, in the past, a method or apparatus for assembling a large number of blocks to the endless carrier has not been developed.
- the present invention has been made paying attention to the above technical problem, and has as its object to efficiently assemble or manufacture a belt comprising a large number of elements and a ring for binding them in an annular shape.

- FIG. 2 is a view taken in the direction of arrows II in FIG. 1. It is a perspective view which shows an example of a cartridge. It is a front view which shows an example of the jig
- the belt is used, for example, in a continuously variable transmission, and is sandwiched in a winding groove having a V-shaped cross section formed on the outer peripheral portion of the pulley, and as a result, a frictional force generated between the belt and the pulley. It is configured to transmit torque.
- FIG. 8 An example of this is schematically shown in FIG. 8, in which the belt 1 is wound around a driving pulley 2 and a driven pulley 3 that constitute a continuously variable transmission.
- Each of these pulleys 2 and 3 has a fixed sheave and a movable sheave each provided with a tapered surface so as to face each other, thereby forming a winding groove 4 having a V-shaped cross section between these sheaves.
- the movable sheave is configured to change the width of the winding groove 4 by moving the movable sheave back and forth with respect to the fixed sheave by an actuator 5 such as a hydraulic cylinder.
- the belt used in this manner is formed by annularly binding a number of elements with a ring so that the entire belt has an annular shape and both side surfaces are V-shaped or tapered.
- An example of the element 6 constituting the belt 1 shown in FIG. 8 is shown in FIG.
- the element 6 is a metal plate piece, and elements having the same shape and size are arranged in an annular shape with the same posture.
- a convex portion called a dimple 7 and a concave portion (not shown) called a hole into which the dimple 7 is loosely fitted. are formed at one location on both the front and back sides of the element.
- the dimple 7 is formed so as to protrude from the back surface or the front surface as a hole is formed by pressing one portion of the front surface or back surface of the element 6 in the thickness direction to form a hole. Therefore, when the dimple 7 is fitted into the hole of the adjacent element 6, the relative movement of the element 6 in the radial direction, that is, the vertical direction and the horizontal direction is restricted.
- each element 6 is arranged in a ring shape, there is always a place where each element 6 is arranged in a so-called fan-shaped (radial) open state around the center of curvature of the belt 1 without being parallel.
- a locking edge 8 is formed on the element 6 to allow a fan-shaped arrangement with the elements 6 in contact with each other.
- the rocking edge 8 is a boundary line or a boundary region where the thickness of the element changes, and the width direction (direction parallel to the rotation center axis of the pulley) is substantially at the center of the element 6 in the height direction. ).
- the peripheral length on the upper side of the element 6 (the outer peripheral side as the belt 1) becomes longer. Since the circumference of the lower side of the element 6 (inner circumference side as the belt 1) becomes shorter, the interval between the elements 6 becomes narrower. Therefore, the lower part of the element 6 is configured to be thin on the lower end side.
- the rocking edge 8 is where the plate thickness changes between the upper side and the lower side of the element. Therefore, each element 6 rotates in the plate thickness direction around the rocking edge 8, that is, pitching occurs and opens like a fan as described above.
- the locking edge 8 may be formed on either one of the front and back surfaces. For example, the locking edge 8 is formed on the surface from which the dimple 7 protrudes.
- Each element 6 has a saddle surface 10 on which a ring 9 is placed (arranged). Since the saddle surface 10 is in contact with a ring 9 that binds a large number of elements 6, the contact pressure increases when the belt 1 is transmitting torque, whereas the element 6 In the case where the pulleys 2 and 3 are wound around the pulleys 2 and 3 and opened in a fan shape from the linearly arranged state, sliding occurs between the ring 9 and the saddle surface 10, and accordingly, a large frictional force is generated.
- the saddle surface 10 is formed at a position as close as possible to the aforementioned locking edge 8 so that the moment due to the frictional force does not increase. Therefore, the saddle surface 10 is formed at a substantially central portion of each element 6 in the vertical direction.
- the ring 9 in the belt 1 is formed by laminating thin metal strips, and the two rings 9 are arranged adjacent to the saddle surface 10 in the width direction so as to bind the elements 6. It is configured.
- each ring 9 is described as a “ring member”.
- the saddle surface 10 is formed with a width equal to or greater than the width of the two rings 9 arranged side by side.
- the ring is placed on the saddle surface and binds the elements so that the elements maintain an annular arrangement so that the elements do not separate outward in the radial direction.
- the ring also acts to pull out the element from the winding groove when the element is fed out from the winding groove of the pulley. Therefore, in order to prevent the ring from coming out of the element in the radial direction, a retaining portion for holding the ring in a state of being sandwiched between the saddle surface is provided.
- hook portions 11 are provided on both the left and right sides of the element 6 as a retaining portion that extends upward from the saddle surface 10 and covers a part of the upper side of the saddle surface 10.
- the hook portion 11 is a portion having a hook shape (inverted L shape), and the left and right side edges of the ring 9 arranged in parallel to the saddle surface 10 are connected to the saddle surface 10. It is designed to be loosely sandwiched between the two. Therefore, the tip portions of the hook portions 11 are separated from each other, and an opening portion 12 for the saddle surface 10 is formed here.
- the interval between the hook portions 11, in other words, the opening width of the saddle surface 10 is wider than the width of one ring 9 and smaller than the sum of the widths of the two rings 9.
- an example of the belt 1 that is the subject of the present invention is that the width of any one (one) ring 9 is narrower than the width of the opening 12 in the element 6 and two (two) rings 9. Is wider than the width of the opening 12 in the element 6. Therefore, after assembling all the elements 6 to any one ring 9 and then assembling the other ring 9 to those elements 6, the element 6 falls off in the process of assembling the other ring 9. Cannot be assembled. Further, in the state in which the two rings 9 are adjacent to each other in the width direction and arranged in parallel to each other in the same manner as in the assembled state as the belt 1, the entire width becomes wider than the width of the opening 12, so the saddle of the element 6 The surface 10 cannot be inserted as it is.

Since the other ring 9 is inclined and slightly displaced from the center of the element 6 as described above, the other ring 9 passes through the opening 12 without interfering with the hook 11. Enter the saddle surface 10. Then, by increasing the push-down force by the oblique push pusher 34 with respect to the push-up force of the holder 30, the holder 30 is lifted, that is, the element 6 is lifted while the other ring 9 is in contact with the saddle surface 10. Stop. This state is shown in FIG. This raised position is substantially the same as the height of the ring 9 in a state where tension is applied by the rollers 43 and 46 in the jig 40 described above.
- the cartridge 31 is lowered together with the holder 30 while being held by the holder 30. That is, the element 6 is removed from the cartridge 31 and remains attached to the ring 9. Therefore, the traverser 22 is moved backward to return the holder 30 to the original position, and is ready for assembly of the next group of elements 6.
- the group of elements 6 that have been assembled are moved to one of the rollers 43 and 46 by rotating the rollers 43 and 46 in the jig 40 and running the ring 9, and from the above-mentioned assembly position.
- the ring 9 and the element 6 that are prevented from being detached by the hook portion 11 are assembled, the element 6 is moved in the horizontal direction and the vertical direction.
- Each ring 9 can be inserted into the saddle surface 10 from the opening 12 of the element 6 and inserted into the hook portion 11 by pushing down the ring 9. Since the operation of the process is extremely simple, the belt 1 can be assembled or manufactured easily and efficiently.
- the above-described specific example is an example in which the element 6 is annularly bound by the two rings 9 and the belt 1 is assembled so that the entire width of the two rings 9 is wider than the opening width of the opening 12 of the element 6.
- the present invention is not limited to the above specific example, and can also be applied to a case where a belt is assembled by assembling a single ring and element wider than the width of the opening 12. In short, the side edge of any of the rings is pushed down and tilted, and is slightly displaced in the width direction so that the ring is accommodated on the saddle surface of the element without causing interference with the retaining portion. That's fine.
