BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, the assembling apparatus 1 includes a base 11, a disk portion 12 arranged on the base 11, a cage inserting portion 13 for inserting the cage 2 into the disk portion 12, and a A cage positioning part 14 that presses the cage 2 that has been thrown in, an inner throwing part 15 that puts the inner 3 into the cage 2, an inner reversing part 16 that changes the direction of the inner 3 put into the cage 2, and the cage 2. A dispensing part 17 for dispensing the inner cage assembled with the inner 3 to the outside is provided.

As shown in FIG. 2, the cage 2 has a substantially annular shape and has a plurality of windows on its outer peripheral surface. For example, the outer peripheral surface of the cage 2 is provided with six windows at regular intervals in the circumferential direction. Hereinafter, the Z direction shown in FIG. 2 is defined as the axial direction, and the XY directions are defined as the radial direction. In addition, let the space inside the cage 2 in which the inner|underwear 3 is thrown into the cage 2 be a hollow part.

As shown in FIG. 3, the inner 3 has a ring shape with six ball grooves provided at regular intervals on the outer circumference. Hereinafter, the Z direction shown in FIG. 3 is defined as the axial direction, and the XY directions are defined as the radial direction.

As shown in FIG. 1, the base 11 has a rectangular plate surface. The base 11 is arranged so that one side is high and the opposite side is low. In other words, the base 11 is arranged in the assembling apparatus 1 such that the normal direction from the surface is an oblique direction. In the following description, the vertical direction on the surface of the base 11 is the Y1 direction, the normal direction from the surface is the Z1 direction, and the horizontal direction perpendicular to the Y1 and Z1 directions is the X1 direction. For example, when the height of the assembling apparatus 1 itself is the Z direction, the front-rear direction is the Y direction, and the lateral direction is the X direction, the X1 direction is the same direction as the X direction. Regarding the Z1 direction, the side on which the cage 2 is placed with respect to the base 11 is defined as the front side.

As shown in FIG. 1 , the disc portion 12 is arranged on the surface of the base 11 . That is, the normal direction of the disk main body 21 of the disk portion 12 and the normal direction of the base 11 are arranged to be the same. As shown in FIGS. 4 and 5, the disc portion 12 includes a disc main body 21, a Geneva gear 22 disposed so as to be in contact with the central axis of the disc main body 21, and a plurality of phases protruding to the front side in the Z1 direction. and an ejection guide 23 are provided. It should be noted that the disk portion 12 will be described as rotating clockwise when viewed from the Z1 front side.

Geneva gear 22 is a mechanism that converts continuous rotary motion into intermittent rotation. Specifically, the Geneva gear 22 is provided in the vicinity of the central axis of the disk body 21 and gives a force to rotate the disk body 21 by 60°. As a result, the disc portion 12 rotates around the central axis extending in the Z1 direction. Therefore, when the cage 2 is sandwiched between the phase adjusting guides 23 , the cage 2 moves simultaneously with the rotation of the disc portion 12 .

The phasing guide 23 protrudes from the disk main body 21 toward the front side in the Z1 direction, and is arranged on the same circumference with respect to the central axis. Each of the phase adjustment guides 23 has a substantially elliptical shape when viewed from the Z1 front direction, and is arranged so that its major axis direction substantially coincides with the radial direction of the disk main body 21 . Here, six phase adjusting guides 23 are provided on the disk body 21 at equal intervals on the same circumference.

In the disc portion 12 , the cage 2 is arranged between the adjacent phasing guides 23 . At this time, the positions of the windows of the cage 2 and the bulging of the phase finding guide 23 in the circumferential direction are matched, so that two points of the cage 2 are determined and the phase of the cage 2 is determined.

The cage insertion part 13 is a part where the cage 2 is inserted into the disk part 12 . As shown in FIGS. 4 and 5 , the cage insertion part 13 is located on the left side of the disk part 12 in the X1 direction and at a position approximately 60° from the upper direction in the Y1 direction with respect to the disk part 12. The cage 2 is arranged between the guides 23 so that the cage 2 can be inserted.

In addition, the cage insertion portion 13 is arranged such that the inner end, which is the end closer to the disc portion 12, is lower in the Y1 direction, and the outer end, which is the end farther from the disc portion 12, is higher in the Y1 direction. is arranged to be 20°. When the cage 2 is inserted into the cage loading section 13 from the outside with the Z1 direction being the axial direction and the X1 and Y1 directions being the radial directions, the cage 2 rotates in the cage loading section 13 due to its own weight. , reaches the disc portion 12 .

The cage positioning portion 14 is provided above the disk portion 12 in the Y1 direction. The cage positioning portion 14 includes a cage pressing base 31 having a spring mechanism and a cage pressing portion 32 .

The cage retainer base 31 is connected to a disk-shaped cage retainer 32 . The cage pressing base 31 is connected to the base 11 via a spring mechanism. Further, the cage pressing base 31 operates only in the Y1 direction.

For example, the cage presser 32 is a disk having approximately the same size as the cage 2 . The cage retainer 32 presses and fixes the cage 2 while operating only in the Y1 direction together with the cage retainer base 31 .

More specifically, when the cage 2 is positioned upward in the Y1 direction by the rotation of the disk portion 12, the cage 2 rotates clockwise and counterclockwise by 60° from the downward direction in the Y1 direction. are guided by the phase adjusting guide 23 at two points of the position of . At this time, the outer peripheral surface of the disk-shaped cage retainer 32 enters the window arranged on the upper side in the Y1 direction of the cage 2, and a downward force in the Y1 direction is applied. As a result, the cage presser 32 presses and fixes the cage 2 .

As shown in FIG. 6, the inner throwing portion 15 includes an inner chute 41 that brings the inner 3 closer to the disk portion 12, a pusher 42 that moves the inner 3 transferred by the inner chute 41 in the X1 direction, an inner guide 43 for guiding the position of the inner 3 before insertion, an inner lock 44 for locking the inner 3 in a state in which the cage 2 faces the inner 3, an unlock pin 45 for unlocking the inner lock 44, Prepare.

For example, it is assumed that these components of the inner throwing portion 15 are provided on a base 46 for the inner throwing portion arranged at a predetermined distance from the front side of the disk portion 12 in the Z1 direction. .

Here, as shown in FIG. 1 , the innerwear inserting portion 15 is arranged on the Z1 front side with respect to the disk portion 12 . Further, the inner loading portion 15 is arranged so as to face the cage 2 fixed by the cage retainer 32 above Y1 of the disk portion 12 when the inner 3 is locked by the inner lock 44. ing.

As shown in FIG. 6, the inner chute 41 is a throw-in portion for the inner 3 having one end located near the disk portion 12 on the front side of the disk portion 12 and the other end located far from the disk portion 12 . . It should be noted that they are arranged such that the end portion closer to the disk portion 12 is at a lower position in the Z direction, and the other end portion is at a higher position in the Z direction. Thus, when the inner 3 is thrown in from the other end of the inner chute 41 with its axial direction set to the X1 direction, it rolls due to gravity and reaches the end near the disc portion 12 .

The disc-side end portion of the inner chute 41 is arranged to be at substantially the same height in the Z direction as the position of the cage 2 fixed by the cage retainer 32 in the disc portion 12, but deviated in the X1 direction. It is

The cut-out pusher 42 moves the inner 3, which has been transferred to the end on the disc portion 12 side in the inner chute 41, in the X1 direction. As a result, the cut-out pusher 42 arranges the inner 3 to be inserted into the cage 2 so as to face the cage 2 . For example, when a plurality of inner 3 are thrown into the inner chute 41 , the cut-out pusher 42 cuts out one inner 3 to be thrown into the cage 2 so as to face the cage 2 . can be set to

Here, when the inner 3 faces the cage 2, the axial direction of the inner 3 is the X1 direction.

As shown in FIGS. 6 and 7 , the inner guide 43 adjusts the position of the inner 3 with respect to the cage 2 on the disc portion 12 . For example, the inner guide 43 can move in the Y direction while the inner 3 is fixed. Thereby, the inner guide 43 can adjust the distance between the position of the inner 3 and the cage 2 on the disc portion 12 .

When the inner lock 44 is moved by the cut-out pusher 42 and faces the cage 2 on the disk portion 12, the inner lock 44 is formed by inserting a projecting portion having a shape that matches the shape of the ball groove of the inner 3. , and a ball groove shaft provided on the lower side of the inner 3 to hold the inner 3.

The lock release pin 45 releases the state in which the inner 3 is held by the inner lock 44 . As a result, the inner 3 falls while rolling toward the hollow portion of the cage 2 and is inserted.

As shown in FIG. 1, the inner reversing portion 16 is arranged near the upper portion in the Y1 direction and near the right portion in the X1 direction of the disk portion 12 . The inner reversing portion 16 includes a guide vane portion 51 inserted into the cage 2 and an inner reversal suppressing plate 52 that suppresses reversing operation of the inner 3 that is reversed by the guide vane portion 51 .

As shown in FIG. 8, one end of the guide blade portion 51 is fixed to the base 46 for the inner inserting portion, and the other end extends substantially in the Y direction. Further, for example, the guide blade portion 51 is arranged so that the surface of the blade is in the X1 direction. When the disc portion 12 rotates and the cage 2 into which the inner 3 is inserted from above in the Y1 direction moves along with the rotation of the disc portion 12, the guide vanes 51 come into contact with the side surfaces of the inner 3. Change the axial direction of the inner 3 to a right angle.

As shown in FIGS. 9A and 9B, the blade surface of the guide blade portion 51 has the same spherical shape as the side surface of the inner 3. As shown in FIGS. 9(a) is a front view of the guide blade portion 51 viewed from the blade surface side, and FIG. 9(b) is a top view. As a result, the inner 3 can be firmly grasped by the guide blades 51, and the inner 3 can be smoothly laid down in the cage 2 to be reversed. In other words, the guide vane portion 51 can change the axial direction of the inner 3 from the X1 direction to the Z1 direction by 90 degrees so that the inner 3 is assembled to the cage 2 . In addition, the guide blade portion 51 is of a movable type in which one end is not fixed, and is a mechanism in which the force is released in accordance with the rotation of the disc portion 12 .

The inner reversal suppressing plate 52 is a plate that suppresses the inner 3 reversed by the guide blade portion 51 from being excessively reversed. The inner reversal suppressing plate 52 is arranged so that the surface of the plate is in the Z1 direction. Further, the inner reversal suppression plate 52 is slidably connected to the base 11 and can move in the X1 direction according to the position of the guide blade portion 51 (see FIG. 1). Specifically, the inner reversal suppressing plate 52 is spring movable in order to reduce interference with the guide blade portion 51 .

The inner reversal suppressing plate 52 prevents the portion on the opposite side of the central shaft from the portion where the guide vane portion 51 abuts against the inner 3 when the inner 3 is reversed by the guide vane portion 51. suppress. That is, the inner reversal suppressing plate 52 suppresses reversing by contacting the plate surface with the inner 3 when the inner 3 is subjected to excessive reversing force.

As shown in FIG. 1 , the dispensing section 17 dispenses the inner cage, which is the inner cage attached to the cage 2 by the inner reversing section 16 . Note that the payout portion 17 is provided near the lower side of the base 11 in the Y1 direction. Therefore, the ejector 17 ejects the inner cage that has been conveyed clockwise when viewed from the Z1 front side by the operation of the disc portion 12 and has reached the vicinity of the lower side in the Y1 direction to the outside of the assembling apparatus 1 .

Next, with reference to FIG. 10, an example of the flow for assembling the inner 3 to the cage 2 using the assembling apparatus 1 will be described.

First, the cage 2 is fixed on the disc portion 12 .

The cage 2 is loaded into the cage loading unit 13 (step S1). The thrown-in cage 2 reaches the disc portion 12 and is arranged between the adjacent phasing guides 23 (step S2).

The disk portion 12 is rotated by 60° by the operation of the Geneva gear 22, and the cage 2 is arranged on the upper side in the Y1 direction (step S3). Then, the cage 2 is fixed by the cage retainer 32 of the cage positioning portion 14 .

More specifically, at position A shown in FIG. 4, the cage is not determined to be transported, and moves to position B while rotating due to its own weight. At this time, since the cage rotates while the windows of the cage follow the phasing guide 23, the two points of the cage 2 are settled in the phasing guide 23 and two points are determined. Since the cage positioning part 14 is a mechanism that moves up and down in the Y1 direction when it is rotated from the position B to the position C, one point of the cage window arranged on the upper side of the cage 2 in the Y1 direction is moved by the force of the spring. It is possible to determine the phase at a total of three points.

Next, the inner 3 is put into the fixed cage 2 .

The inner 3 is thrown into the inner chute 41 (step S4).

One of the inners 3 thrown into the inner chute 41 is moved by the cut-out pusher 42 and arranged so as to be at the throwing position into the cage 2 (step S5).

The inner guide 43 is operated to adjust the state in which the inner 3 is close to the cage 2 (step S6). At this time, since the inner 3 is locked by the inner lock 44, it is in a state where it does not drop to the cage 2 side.

The unlock pin 45 is operated to unlock the inner lock 44 (step S7). As shown in FIG. 7 , the inner 3 drops toward the cage 2 while rotating and is inserted into the hollow portion of the cage 2 .

For example, when the inner lock 44 is released, the inner 3 rotates and drops about the ball groove shaft inserted in the ball groove arranged below the inner 3 . At this time, the inner 3 contacts the edge of the cage 2 at the bottom of the ball groove next to the fulcrum. The inner 3 is inserted into the cage 2 by rotating and dropping toward the inside of the cage 2 using the point of contact with the cage 2 as a second fulcrum.

At this time, the axial direction of the cage 2 is the Z1 direction, and the axial direction of the inner 3 is the X1 direction. That is, the relationship between the axial direction of the cage 2 and the axial direction of the inner 3 is substantially vertical.

Next, the axial direction of the inner 3 is changed.

The disc portion 12 is rotated (step S8). As a result, the cage 2 into which the inner 3 is inserted moves rightward in the X1 direction from the upper portion of the disk portion 12 in the Y1 direction in accordance with the rotation of the disk portion 12 .

During this rotating operation, the blade surface of the guide blade portion 51 comes into contact with the inner 3 (step S9). More specifically, a portion of the inner 3 protruding from the cage 2 toward the front side in the Z1 direction contacts the guide blade portion 51 . As a result, the guide blade portion 51 is reversed by 90 degrees so that the axial direction of the inner 3 is changed from the X1 direction to the Z1 direction (step S10).

By making the shape of the guide vane portion 51 the same spherical shape as the side surface of the inner 3, the surface of the inner 3 can be pressed and the inner 3 can be turned over smoothly. Further, when the guide vane portion 51 exerts a force that causes the inner 3 to be excessively reversed, the inner reversal suppressing plate 52 suppresses the reversal. As a result, an inner cage in which the inner 3 is attached to the cage 2 is formed.

After that, the disk portion 12 is further operated to convey the inner cage downward in the Y1 direction and to be delivered from the delivery portion 17 (step S11).

In this manner, the positioning of the cage 2, the insertion of the inner 3 into the cage 2, and the reversal of the inner 3 in the cage 2 can be performed, respectively, and the inner 3 can be attached to the cage 2. More specifically, when the cage 2 is supplied to the disk portion 12, the cage 2 can be rotated and always fixed in the same phase and at the same position. In addition, in the inner throwing portion 15, the operation for combining the inner 3 with the cage 2 can be realized in a simple form of dropping and throwing the inner 3. Furthermore, the reversal of the inner 3 in the cage 2 can be efficiently executed using the guide blade portion 51 .

In addition, from the above, it is possible to attach the inner 3 to the cage 2 in accordance with the rotation of the disk portion 12 . Therefore, for example, one assembling apparatus 1 can continuously perform the reversal of the inner 3 put into the cage 2, the putting of another inner 3 into another cage 2, and the execution of positioning of the other cage 2. can be executed by Therefore, the working time can be shortened.

Therefore, it is possible to carry out the work without relying on the skill such as intuition and tricks of the worker, and to construct a line for automatically executing the assembly and to reduce the cost.

It should be noted that the present invention is not limited to the above embodiments, and can be modified as appropriate without departing from the scope of the invention.
