  2. Description of the Related Art Conventionally, in a product assembly process, a parts feeder that vibrates a conveyance path surface is widely used as a component supply device that sequentially sends various components constituting the product to an assembly station (see, for example, Patent Document 1). . In this parts feeder, for example, a plurality of parts are arranged on a conveyance path surface, and the parts are sequentially aligned and conveyed to an assembly station by vibrating the conveyance path surface.

JP-A-11-342912

  However, in this type of parts feeder that vibrates the conveying path surface, the conveying path surface and the parts come into contact with each other and are conveyed by friction. For example, a lightweight part that does not reach 1 gram of components to be conveyed is used. In some cases, the frictional force generated between the conveying path surface and the part is small, so even if the conveying path surface vibrates, the part remains floating, and it is difficult to convey the part in the direction to be conveyed due to vibration. There was a bug. That is, in the conventional parts feeder that vibrates the conveyance path surface, when the object to be conveyed is an extremely light component, there is a problem that a conveyance failure of the component occurs and good component supply is not performed.

  An object of the present invention is to provide a component supply apparatus and a component supply method that can perform satisfactory component supply even when a conveyance target is a relatively lightweight component.

  The component supply device according to the present invention includes a rotating container that accommodates a plurality of components and rotates to scrape the components, a receiving device that receives the components that are scraped up and dropped, and the receiving device from the inside of the rotating container. Receiving means moving means to be pulled out to the outside.

  The receiver moving means includes a rod-shaped handle having the receiver provided at the tip, an axial movement mechanism for moving the handle in the longitudinal direction, a swing mechanism for swinging the handle around the base end of the handle, and the handle And a handle rotation mechanism for rotating the handle about a central axis extending in the longitudinal direction of the handle. A suction hole is formed in the receiver, and air is sucked through the suction hole to receive the component received by the receiver. It is also possible to provide a suction device for adsorbing to the receiving tool.

A suction pressure sensor that detects fluctuations in the suction pressure sucked by the suction device when a component is adsorbed to the receiver, and a controller that controls the receiver moving means based on the detection output of the suction pressure sensor. Upon detecting the pressure fluctuation, the controller controls the receiver moving means to pull the receiver from the inside of the rotating container to the outside of the rotating container, and while the suction pressure sensor does not detect the fluctuation of the suction pressure, the controller It is also preferable to control the receiving means moving means so that the parts that are not attracted to the receiving means are dropped from the receiving means and the receiving means is rotated after being rotated about the axis of the handle and then restored every predetermined time. . In this case, before withdrawing the receiving device from the rotating container, the controller rotates the receiving device around the axis of the handle as a center of rotation and drops the components other than the components adsorbed on the receiving device to separate them. It is also possible to control the receiver moving means.

In the component supply method of the present invention, a rotating container containing a plurality of components is rotated to scrape the components inside the rotating container, and the components that are picked up and dropped are received by the receiving tool, and the receiving tool is pulled out from the rotating container. A component supply method for supplying a component pulled out from the inside of a rotating container together with a receiving device, wherein a suction hole is formed in the receiving device, air is sucked through the suction hole, and the component received by the receiving device is received by the receiving device. Before pulling out the receiving tool that is sucked into the tool and receiving the component from the rotating container, the receiving tool is rotated and the components other than the parts sucked into the receiving tool are dropped from the receiving tool and separated .

While the part products are not adsorbed to the receptacle, it is preferable to repeat be restored after rotating the receptacle so as to drop the part that is not adsorbed to the receptacle from the receptacle at predetermined time intervals.

  In the component supply apparatus and the component supply method according to the present invention, since the component that is scraped up and dropped is received by the receiving tool, even if the object to be transported is a relatively lightweight component, the component can be reliably received by the receiving tool. it can. Then, since the received part is pulled out from the rotating container together with the receiving tool, and the part is supplied to the next process, a good part supply can be performed.

  In this case, if the component is adsorbed to the receiving device, it is possible to avoid a situation where the component is detached from the receiving device when the receiving device is moved, and before the receiving device receiving the component is pulled out of the rotating container. By reversing the receiving tool and dropping the parts other than the part sucked by the receiving tool from the receiving tool and separating the parts, it is possible to avoid a situation where parts other than the sucked parts are pulled out of the rotating container. Then, while the parts are not attracted to the receiver, the parts that have fallen to the receiver but are not attracted to the receiver are received by repeating the restoration after being turned upside down in the vertical direction every predetermined time. The component can be dropped from the tool every predetermined time, and then the parts falling on the receiver can be efficiently adsorbed to the receiver.

It is configured to repeat the restoration later every predetermined time.

  Next, the component supply method in the present invention will be described.

  In the component supply method of the present invention, the rotating container 12 containing a plurality of components 11 is rotated to scrape the component 11 inside the rotating container 12, and the component 11 that is scraped and dropped is provided at the tip of the handle 17. It is received by the received receiving tool 16, the handle 17 is moved, the receiving tool 16 is pulled out from the rotating container 12, and the part 11 pulled out from the inside of the rotating container 12 together with the receiving tool 16 is supplied to an assembly station (not shown). And Although each of these operations will be described in detail below, the operations shown below are automatically operated by the controller 27 except for housing the component 11 in the rotating container 12.

  The plurality of parts 11 are accommodated in the rotating container 12 by an operator, the cover plate 12e is opened by a hinge 12f to open the insertion hole 12d formed in the cylindrical body 12a, and a plurality of parts are released from the opened insertion hole 12d. The component 11 is put into the rotary container 12. Thereafter, the insertion hole 12d is sealed by the cover plate 12e, and the work knob 12g is rotated in this state, and a male screw (not shown) connected thereto is screwed to the cylindrical body 12a. This prohibits the opening of the cover plate 12e. Thereafter, the rotating container 12 is rotated. However, the rotation of the rotating container 12 drives the container servomotor 14 to rotate the rotating shaft 14a, thereby causing the rotating container 12 to move along the horizontal central axis of the cylindrical body 12a. Rotate as the center of rotation.

  When the rotating container 12 is rotated, the rotating servo motor 23 is brought close to the rotating container 12 as shown by a one-dot chain line arrow in FIG. 1 by the fluid pressure cylinder 21 which is an axial movement mechanism, and the handle 17 is connected via the extraction hole 12j. A receiver 16 provided at the tip of the container 12 is allowed to enter the inside of the container 12. Further, an aspirator (not shown) is driven to suck air through the air tube 19, the extension hole 17b, and the suction hole 16d.

  When the rotating container 12 rotates, the plurality of parts 11 accommodated in the rotating container 12 are formed radially on the inner periphery of the cylindrical body 12a and are rotated by the plurality of fin members 12h that rotate together with the rotating container 12. It is scraped up. Since the fin members 12h are provided radially around the center of rotation, when the fin member 12h located at the lower part of the container 12 is directed above the container 12, the plurality of parts 11 are scraped up by the fin members 12h. As shown in FIG. 6, the component 11 that has been scraped when the fin member 12 h reaches the upper side falls due to its own weight. In this way, the component 11 that is scraped up and dropped is received by the receiving tool 16 provided at the tip of the handle 17.

  As shown in FIG. 6, the receiving device 16 that receives the component 11 tilts the mounting portion 16 b so that the tip of the mounting portion 16 b is higher than the fixing portion 16 a to which the base end is connected. Make it stand by. By tilting the mounting portion 16b in this manner, the ring-shaped component 11 that has dropped onto the mounting portion 16b is positioned between the mounting portion 16b and the covering portion 16c along the tilt, as indicated by a solid arrow. The outer periphery can be brought into contact with the fixed portion 16a. On the other hand, the fixed portion 16a between the placement portion 16b and the cover portion 16c is provided with the end of the suction hole 16d open, so that the outer periphery enters between the placement portion 16b and the cover portion 16c and the fixed portion 16a. The component 11 that has come into contact with is attracted to the receiving member 16 by the air sucked from the suction hole 16d.

  While the component 11 is not attracted to the support 16, the controller 27 controls the support moving means 20, and as shown in FIG. 9, it is predetermined that the vertical direction of the support 16 is reversed and then restored again. Repeat every hour. That is, although the mounting portion 16b is inclined and waited, if the component 11 is not adsorbed to the receiving member 16, the suction pressure sucked by a suction device (not shown) does not increase, and is shown in the suction pressure in the lower part of FIG. Thus, the suction pressure detected by the suction pressure sensor 26 shows a low value. When the state where the suction pressure is low has elapsed for a predetermined time, as shown in the movement of the receiver at the upper end in FIG. 9, the receiver 16 is reversed and then restored again. Furthermore, when the state where the suction pressure is low has elapsed for a predetermined time, the receiver 16 is reversed again and then restored again. Repeat this. As a result, as shown in FIG. 8, the ring-shaped component 11 that has fallen onto the placement portion 16b of the receptacle 16 but does not enter between the placement portion 16b and the cover portion 16c is removed from the receptacle 16 for a predetermined time. The component 11 that is dropped every time and does not enter between the placement portion 16b and the cover portion 16c blocks the space between the placement portion 16b and the cover portion 16c, and another ring-shaped component 11 becomes the placement portion. It is possible to eliminate such a situation that prevents entry between 16b and the cover portion 16c every predetermined time. Here, the predetermined time is preferably about 3 to 10 seconds, and more preferably about 3 to 6 seconds.

  On the other hand, as shown in FIG. 6, when the component 11 that is scraped up and falls enters between the placement portion 16 b and the cover portion 16 c and the outer periphery abuts against the fixing portion 16 a, the component 11 passes through the suction hole 16 d. Adsorbed to the receiving tool 16 by the sucked air. When the component 11 is sucked in this way, the suction hole 16d is blocked by the component 11, and the suction pressure sucked by a suction device (not shown) increases. The fluctuation of the pressure is detected by the suction pressure sensor 26, and the controller 27 recognizes the fact that the component 11 is attracted to the receiving tool 16 by the detection output of the sensor 26. Then, the controller 27 controls the receiver moving means 20 so as to pull out the receiver 16 from the inside of the rotating container 12 to the outside of the rotating container 12.

  Specifically, as shown in FIG. 10, when the component 11 is attracted to the support 16, the suction pressure detected by the suction pressure sensor 26 changes from a low value to a high value. The controller 27 recognizes the fact that the component 11 is adsorbed to the receiving member 16 because the suction pressure has changed from a low value to a high value. Then, the controller 27 reverses the receiver 16 as shown in FIG. 7 from the standby state shown in FIG. 6 and sucks it to the receiver 16 before the receiver 16 receiving the component 11 is pulled out of the rotating container 12. The parts 11 other than the parts 11 are dropped from the receiving tool 16. Thereby, the parts 11 other than the part 11 adsorbed by the receiving tool 16 are prevented from being pulled out of the rotating container 12 together with the adsorbed part 11. FIG. 10 shows a case where the inverted receiver 16 is restored again and then pulled out from the rotating container 12. However, as long as the component 11 does not attract and fall on the receiver 16, the receiver 16 is inverted as shown in FIG. 7. You may pull out from the rotation container 12 in the state shown. The inversion of the receiver 16 is performed by driving a servo motor 23 for rotation in the receiver moving means 20, and by rotating the handle 17 about its axis, the receiver provided at the tip thereof. 16 is inverted.

  Thereafter, the controller 27 controls the receiver moving means 20 to move the handle 17, pulls out the receiver 16 from the rotating container 12, and removes the receiver 11 together with the parts 11 adsorbed by the receiver 16 inside the rotating container 12. Pull out from. This drawing is performed by the fluid pressure cylinder 21 in the receiver moving means 20, and the slider 21 b is moved away from the rotating container 12 together with the rotating servo motor 23 and the handle 17. Then, the receiving tool 16 provided at the tip of the handle 17 is pulled out from the inside of the rotating container 12 to the outside of the rotating container 12, whereby the component 11 can be pulled out from the inside of the rotating container 12 together with the receiving tool 16. Then, although the component 11 pulled out in this way is supplied to the next process, the receiver moving means 20 includes a handle 17 swinging mechanism 22 that swings the handle 17, so that it is shown by a one-dot chain line in FIG. Further, by swinging the handle 17 whose base end is connected to the rotation servomotor 23, the receiving tool 16 at the tip of the handle 17 is moved in an arc shape together with the component 11 pulled out from the rotating container 12, and the component is moved. 11 can be supplied to the next step.

  The component 11 that has been pulled out and moved together with the support 16 is separated from the support 16 and sent out directly or through another transport means (not shown) to a next assembly station (not shown). After the parts 11 have been safely delivered to the assembly station, the receiver 16 from which the parts 11 have been detached is re-entered into the rotating container 12 and the same operation is repeated again, and the parts 11 are sequentially withdrawn from the rotating container 12. Thus, it is sent to an assembly station (not shown).

  As described above, in the component supply device 10 and the component supply method according to the present invention, the component 11 that is scraped up and dropped is received by the receiving tool 16, so that even if the component 11 is relatively light, The part 11 can be received by the receiving tool 16. In this embodiment illustrating the ring-shaped component 11, the mounting portion 16 b and the cover portion 16 c are formed on the receiving member 16, and the ring-shaped component 11 enters between the mounting portion 16 b and the cover portion 16 c. As a result, only the component 11 that has entered between the placement portion 16b and the cover portion 16c is adsorbed to the receiving device 16, and the component 11 is adsorbed to the predetermined position of the receiving device 16 in a predetermined shape. Can be made.

  Although the receptacle 16 to which the component 11 is adsorbed is then pulled out from the rotating container 12, the component 11 is adsorbed to the receptacle 16 so that the component 11 is detached from the receptacle 16 when the receptacle 16 is moved. Such a situation can be avoided. Then, before pulling out the receiving device 16 that has received the component 11 from the rotating container 12, the receiving device 16 is reversed and the components 11 other than the component 11 adsorbed to the receiving device 16 are dropped from the receiving device 16 and separated. It is possible to avoid a situation in which components 11 other than the adsorbed component 11 are pulled out from the rotating container 12. Since the parts 11 sucked and pulled out in a predetermined shape to the receiver 16 in this way are supplied to the next step, that is, an assembly station (not shown), even if the parts 11 to be transported are relatively lightweight Supply of various parts 11 can be performed.

  In the above-described embodiment, the case where the component 11 is a ring-shaped member made of paper has been described. However, the component 11 is not limited to the one made of paper, but made of resin or metal. Alternatively, it may be a ring-shaped resin film. For example, the resin component 11 may be a ring-shaped member made of a polyimide film (trade name; Kapton). Further, the component 11 is light enough to be difficult to convey depending on the vibration of the conveyance path surface in the conventional parts feeder, and the shape thereof is not limited to the ring shape.

  In the above-described embodiment, the receiver 16 having the placement portion 16b and the cover portion 16c is exemplified, and the ring-shaped component 11 is inserted between the placement portion 16b and the cover portion 16c. As long as 11 can be received at a predetermined position of the receiving tool 16 in a predetermined shape, the mounting portion 16b and the cover portion 16c are not necessarily required. That is, the shape of the receiver 16 is appropriately changed depending on the shape of the component 11 to be supplied. For example, when the component is like an O-ring, as shown in FIG. 11, the receiving member 66 includes a main body 66a provided at the tip of the handle 17, and an upper surface from the upper surface of the main body 66a. It may be provided with a truncated cone-shaped fitting portion 66b which is provided so as to protrude toward the edge and into which the component 61 can be fitted. In this case, by forming a plurality of suction holes 66d in the main body portion 66a so as to surround the fitting portion 66b, only the component 61 fitted into the fitting portion 66b can be adsorbed to the receptacle 66. If the receiver 66 is configured to be detachable from the handle 17, it is possible to relatively easily switch to a supply device that is used for parts of other shapes and supplies other parts by simply replacing the receiver 66. It becomes.

  Further, in the above-described embodiment, the cylindrical rotating container 12 in which both sides of the cylindrical body 12a are sealed with the disks 12b and 12c has been described. However, the rotating container 12 accommodates a plurality of components 11. As long as the part 11 is rotated so as to scrape up the part 11, it may be in the shape of a prism such as a quadrangular, pentagonal or hexagonal shape.
