Description

  The present invention relates to a ring dispensing method and apparatus for dispensing a plurality of metal rings cut from a thin metal drum in a ring shape one by one.

  For example, in a power transmission belt employed in a continuously variable transmission, a laminated ring formed by laminating a plurality of metal ring members is used in order to bind together a plurality of elements arranged in a ring shape. It is done. The metal ring constituting this type of laminated ring is formed by cutting a cylindrical drum formed by welding both ends of a rectangular metal thin plate into a ring shape with a predetermined width.

  Conventionally, when forming a metal ring by cutting a cylindrical drum every predetermined width, for example, as seen in Patent Document 1, the drum is used as a rotating cutting holder having a shape corresponding to the drum. Holding and rotating the drum through the cutting holder, the blade is cut at a predetermined width in the circumferential direction of the drum. The plurality of metal rings formed in a ring shape from the drum are paid out from the cutting holder and sent to a subsequent process such as a shaping process.

By the way, when a plurality of metal rings are sent to a subsequent process such as a shaping process, the metal rings are introduced one by one into, for example, a discharge conveyance path. In this case, a plurality of metal rings are pulled out from the cutting holder at once and dropped into a receiving box or the like, and then manually inserted into the payout conveyance path. Alternatively, the metal rings are pulled out from the cutting holder one by one by manual work and put into the payout conveyance path. However, such a manual payout operation is extremely time-consuming and has a disadvantage of poor work efficiency.
No. 02/028580 (FIG. 1)

  In order to eliminate such inconvenience, the present invention can smoothly dispense a plurality of metal rings for product cut from a metal thin drum one by one without manual work, thereby dramatically improving work efficiency. It is an object of the present invention to provide a ring delivery method and apparatus that can be improved.

  In order to achieve such an object, the present invention is formed by cutting a drum formed in a cylindrical shape by a thin metal plate from the inside by holding the drum by a drum holding mechanism and then cutting the drum into a circular shape. A ring dispensing device that dispenses a plurality of metal rings one by one, maintaining a state in which a plurality of metal rings cut and formed from a drum are arranged in the same axial direction, and releasing the holding by the drum holding mechanism A holding release step and a spiral feed groove having a width dimension corresponding to the width dimension of the metal ring after the plurality of metal rings released from the holding by the drum holding mechanism are conveyed while maintaining their arrangement state. A ring mounting step for mounting on a rotatable feed rotary shaft formed on the outer periphery, and a metal ring mounted on the feed rotary shaft to rotate the feed rotary shaft Along said feed groove guided by causing, characterized in that it comprises a payout process for sequentially dispenses one by one each of the metal rings from the tip of the rotary shaft feeding said.

  According to the present invention, after the holding release step, the metal rings are conveyed while maintaining a state in which they are arranged in the same axial direction, and a plurality of metal rings are sent out and held on the rotating shaft by the ring mounting step, and then the payout is performed. The feed rotation shaft is rotated according to the process. Thereby, since a metal ring is sent out along a spiral feed groove, a metal ring can be paid out one by one reliably without manual work, and work efficiency can be improved.

  Further, according to the present invention, in the dispensing step, prior to the rotation start of the delivery rotary shaft, a regulating member extending in the axial direction of the delivery rotary shaft is brought close to or in contact with the outer periphery of the delivery rotary shaft, and the delivery It restricts the movement of the metal ring held on the rotating shaft in the radial direction.

  When the metal ring is delivered along the feed groove by the rotation of the delivery rotary shaft, the metal ring can be delivered quickly by making the rotational speed of the delivery rotary shaft relatively high. However, if the rotational speed of the feed rotating shaft is high, the metal ring guided by the feed groove may vibrate and come off from the feed groove.

  Therefore, in the present invention, the movement of the metal ring in the radial direction is restricted by bringing the restricting member closer to or in contact with the outer periphery of the feed rotation shaft in the payout step, so that the metal ring comes off the feed groove. Can be reliably prevented.

  In the present invention, a drum formed in a cylindrical shape by a metal thin plate is held from the inside by a drum holding mechanism and the drum is cut into a ring shape, and then a plurality of metal rings formed by the cutting are removed. A ring dispensing device for dispensing one by one, a rotatable delivery rotation for mounting and holding a plurality of metal rings cut from a drum and released from holding by the drum holding mechanism in the same axial direction A shaft, a spiral feed groove formed on the outer periphery of the feed rotation shaft and having a width corresponding to the width of the metal ring, and a metal ring supported by the feed groove along the feed groove And a rotation drive means for rotating the delivery rotary shaft so as to be guided and detached from the tip of the delivery rotary shaft.

  In the dispensing device of the present invention, the plurality of metal rings cut and formed from the drum held by the drum holding mechanism are held on the delivery rotary shaft while maintaining the arrangement state. A plurality of metal rings can be transported and mounted very smoothly. And since the feed rotating shaft is provided with the spiral feed groove, the metal ring guided by the feed groove is surely detached one by one from the tip of the feed rotating shaft only by rotating the feed rotating shaft by the driving means. Can be paid out.

  As described above, according to the present invention, a dispensing device can be simply provided, and a plurality of metal rings cut and formed from a metal thin plate drum can be smoothly dispensed one by one without manual operation. Work efficiency can be dramatically improved.

  In the dispensing device according to the present invention, a regulating member that extends in the axial direction of the delivery rotating shaft and that can be moved forward and backward toward the outer periphery of the delivery rotating shaft, and the delivery member rotates forward and backward. And an advancing / retreating drive means for approaching or contacting the outer periphery of the shaft, and the restricting member is a metal held on the delivery rotating shaft when the delivery rotating shaft is rotated when approaching or contacting the outer periphery of the delivery rotating shaft. The movement of the ring in the radial direction is restricted.

  Specifically, the regulating member may be a rod-shaped member extending over substantially the entire length of the feed rotating shaft, or may be a rotary shaft that extends over the entire length of the feed rotating shaft in parallel with the axis of the feed rotating shaft. You may employ | adopt the roller provided rotatably. When a roller is employed as the restricting member, the outer periphery of the roller can be brought into contact with the outer periphery of the delivery rotary shaft, and the roller can be rotated following the rotation of the delivery rotary shaft. In addition, by bringing the outer periphery of the roller into contact with the outer periphery of the feed rotating shaft, the open side of the feed groove can be covered with the roller. As a result, the metal ring can be reliably regulated in the feed groove, the metal ring can be prevented from coming off, and the feed rotary shaft can be rotated at high speed. In addition, when a roller is used, a spiral groove corresponding to the feed groove of the feed rotation shaft is formed on the outer periphery of the roller, thereby forming a feed groove of the feed rotation shaft and a spiral groove of the roller. The metal ring can be reliably guided in the feed-out direction while maintaining a state in which a part of the metal ring is accommodated in the space to be formed.

  In the dispensing device of the present invention, it is preferable that an outer diameter of the delivery rotating shaft is 1 to 3 mm smaller than an inner diameter of the metal ring. In order to mount the metal ring on the outer periphery of the delivery rotary shaft, the outer diameter of the delivery rotary shaft is formed smaller than the inner diameter of the metal ring. At this time, if the difference between the outer diameter of the feed rotating shaft and the inner diameter of the metal ring is larger than 3 mm, a gap between the feed rotating shaft and the metal ring is formed relatively large. There is a possibility that the deflection becomes large, and collision or contact occurs between adjacent metal rings, and smooth guidance by the feed groove is hindered. Further, if the difference between the outer diameter of the delivery rotary shaft and the inner diameter of the metal ring is smaller than 1 mm, it is difficult to attach the metal ring to the delivery rotary shaft. Therefore, in the present invention, by forming the outer diameter of the delivery rotary shaft to be 1 to 3 mm smaller than the inner diameter of the metal ring, the metal ring can be easily attached to the delivery rotary shaft, and the delivery rotary shaft It is possible to reliably guide the metal ring along the feed groove in the payout direction by reducing the deflection of the metal ring accompanying the rotation.

  An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an explanatory view showing a ring payout device according to the present embodiment, FIG. 2 is an explanatory view showing the operation of the ring payout device according to the present embodiment, and FIG. 3 is an explanatory view showing a part of FIG. FIG. 4 is an explanatory view showing a ring payout method in the present embodiment, and FIG. 5 is a cross-sectional explanatory view of a main part in a ring payout device of another embodiment.

  As shown in FIG. 1, the ring dispensing device 1 of the present embodiment includes a cylindrical delivery rotating shaft 2 that holds and holds a plurality of metal rings W arranged in the same axial direction. The delivery rotary shaft 2 is rotatably supported by a support frame 4 erected on the machine base 3 via a bearing member 5, and a distal end of the delivery rotary shaft 2 faces above the payout conveyance path 6. . The delivery rotary shaft 2 is rotationally driven by a motor 8 (rotation drive means) through a gear box 7 connected to the bearing member 5. The payout conveyance path 6 is constituted by a conveyor, and sends the metal ring W to a subsequent process such as a shaping process.

  A spiral feed groove 9 is formed on the outer periphery of the feed rotary shaft 2. The feed groove 9 is formed to have a width slightly larger than the width dimension of the metal ring W, and has a depth dimension larger than the thickness of the metal ring W. Further, the outer diameter of the feed rotating shaft 2 is formed to be 1 to 3 mm smaller than the inner diameter of the metal ring W.

  In addition, the movement of the metal ring W in the radial direction is restricted above the feed rotating shaft 2 so that the metal ring W held on the feed rotating shaft 2 is smoothly fed out while being housed in the feed groove 9. Thus, there are provided restricting means 10 for preventing the metal ring W from being detached from the feed groove 9 during the delivery.

  The regulating means 10 includes a regulating roller 11 (regulating member) and an elevating cylinder 12 (advancing / retreating driving means) that raises and lowers the regulating roller 11. The regulating roller 11 is rotatably held by a rotation shaft 13 parallel to the rotation axis of the delivery rotation shaft 2, and the rotation shaft 13 is supported by a bracket 14 having a U-shape when viewed from the side.

  The elevating cylinder 12 is supported at a position above the motor 8 at the upper end of the support frame 4, and the bracket 14 supporting the restriction roller 11 is connected to the tip of the piston rod 15. Thereby, the restriction roller 11 is raised and lowered by the expansion and contraction of the piston rod 15 by the raising and lowering cylinder 12, and when the restriction roller 11 is lowered, the restriction roller 11 is brought into contact with the delivery rotating shaft 2.

  When the regulating roller 11 abuts on the feeding rotary shaft 2, the opening side of the feeding groove 9 is covered by the regulating roller 11, and the metal ring W can be prevented from coming off from the feeding groove 9. In addition, since the regulation roller 11 is rotatable, the regulating roller 11 abuts on the delivery rotary shaft 2 and rotates following the delivery rotary shaft 2 so that the rotation of the delivery rotary shaft 2 is not hindered. The regulation roller 11 may be close to a position where the metal ring W can be prevented from coming off from the feed groove 9 without contacting the feed rotary shaft 2. In this case, the distance between the outer periphery of the feed rotating shaft 2 and the outer periphery of the regulating roller 11 is preferably slightly smaller than the thickness dimension of the metal ring W, for example.

  The operation of the dispensing device 1 having the above configuration will be described. As shown in FIG. 1, a plurality of metal rings W are mounted on the delivery rotary shaft 2. Thereby, each metal ring W is held in a state of being hooked one by one in the feed groove 9 on the outer periphery of the feed rotating shaft 2. Next, as shown in FIG. 2, the regulation roller 11 is lowered by the drive of the elevating cylinder 12 and comes into contact with the delivery rotary shaft 2. When the delivery rotary shaft 2 is rotated by the motor 8 in this state, each metal ring W is sent toward the tip of the delivery rotary shaft 2 by the spiral feed groove 9, and the delivery conveyance is performed from the tip of the delivery rotary shaft 2. Fall one by one toward the road 6. As a result, the metal rings W can be reliably dispensed one by one. In addition, since the regulating roller 11 is in contact with the delivery rotating shaft 2, the metal ring W is regulated by the regulating roller 11 and does not come off the feeding groove 9 even if the delivery rotating shaft 2 is rotated at a high speed. It is reliably sent out along the feed groove 9.

  Next, a metal ring payout method using the payout device 1 of the present embodiment will be described. First, as shown in FIG. 4A, a metal ring held by a drum holding mechanism 16 of a drum cutting device is used. A plurality of metal rings W are cut and formed from the thin drum. Although not shown, the drum is formed by bending a rectangular metal thin plate into a cylindrical shape and welding both edges. Each metal ring W is formed by being cut into a ring shape by pressing the disk-shaped cutting blade 17 at a predetermined width while rotating the drum held by the drum holding mechanism 16.

  The plurality of metal rings W cut from the drum while being held by the drum holding mechanism 16 are then pressed and clamped from the outer periphery by a cylindrical ring pull-out member 18 that is divided vertically as shown in FIG. 4B. Then, it is pulled out from the drum holding mechanism 16 in the axial direction to release the holding (holding releasing step).

  Subsequently, as shown in FIG. 4C, the metal ring W is attached to the feed rotary shaft 2 so that the feed rotary shaft 2 is inserted in the axial direction of the metal ring W held by the ring pulling member 18. Then, the ring pull-out member 18 is divided up and down, and the press-clamping of the metal ring W by the ring pull-out member 18 is released (ring mounting step). At this time, the restricting means 10 maintains the restricting roller 11 at the raised position by the elevating cylinder 12 and prevents interference between the restricting roller 11 and the ring pulling member 18.

  As described above, as shown in FIGS. 2 and 3, the restricting means 10 lowers the restricting roller 11 by the elevating cylinder 12 to bring the restricting roller 11 into contact with the feed rotating shaft 2, and then the feed rotating shaft. Rotate 2 As a result, the spiral feed groove 9 feeds out each metal ring W, and the metal rings W are delivered one by one from the tip of the delivery rotary shaft 2 onto the delivery path 6 (dispensing step).

  As described above, by adopting the dispensing device 1 of the present embodiment, a plurality of metal rings W cut from the drum can be reliably dispensed one by one without any manual work. Can be improved.

  In the present embodiment, the restriction roller 11 is used as the restriction member in the present invention. However, as shown in FIG. 5, the feed groove 9 of the feed rotary shaft 2 is provided on the outer periphery of the restriction roller 11. A spiral groove 19 corresponding to may be formed. By doing so, it is possible to reliably maintain a state in which a part of the metal ring W is accommodated in the space formed by the feed groove 9 of the feed rotation shaft 2 and the spiral groove 19 of the regulating roller 11. . And even if the metal ring W swings and comes off from the feed groove 9 as the feed rotation shaft 2 rotates, the spiral groove 19 of the regulating roller 11 regulates the metal ring W and prevents the metal ring W from coming off at the same time. Since W is guided in the delivery direction, the metal ring W can be reliably delivered to the delivery path 6 while reliably preventing the metal ring W from coming off. Moreover, the space formed by the feed groove 9 of the feed rotation shaft 2 and the spiral groove 19 of the regulating roller 11 only needs to be large enough to accommodate the metal ring W, as shown in FIG. The feed groove 9 of the feed rotary shaft 2 can be made shallower than the thickness dimension of the metal ring W. When the metal ring W is mounted on the feed rotary shaft 2 in the above-described ring mounting process, the metal ring W and the feed groove 9 Interference with both side walls can be prevented, and the metal ring W can be mounted very easily.

  In the present embodiment, the restriction roller 11 is used as the restriction member. However, although not shown, a rod-like body extending in the axial direction of the delivery rotary shaft 2 may be adopted instead of the restriction roller 11. Good. In this case, the rod-shaped body is not brought into contact with the outer periphery of the delivery rotary shaft 2 but is allowed to approach the outer circumference of the delivery rotary shaft 2 at a distance slightly smaller than the thickness dimension of the metal ring W. preferable.

  Moreover, in this embodiment, although the example which provided the said control means 10 was shown in order to perform the quick discharge of the metal ring W by rotating the delivery rotating shaft 2 at high speed, the delivery rotating shaft 2 is rotated at low speed. In this case, since the swing of the metal ring W is small and does not come off from the feed groove 9, the restriction means 10 need not be provided.
