[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for inserting gears into gears.

[0002]

2. Description of the Related Art A conventional method and apparatus for inserting and engaging a gear of this kind will be described below with reference to the drawings. FIG. 2 is a perspective view schematically showing an outline of an insertion device capable of implementing a conventional gear insertion method.

In the figure, 1 is a gear supply device, 2 is a gear, 3 is a gear take-out portion provided in the gear supply device 1, and 4 is a gear 2
5 is a suction shaft for sucking the gear 2, 6 is a rotating device for rotating the suction shaft 5, 7 is a transfer device, 8 is a lifting device, 9 is a gear 2 into which the gear 2 is finally inserted, and These are a plurality of spindles for constituting a power transmission mechanism using gears.

In order to finally assemble the power transmission mechanism using the plurality of gears, the gear tooth inserting / inserting apparatus is an apparatus which inserts the gears constituting the gear while aligning the gears with the support shaft. First, the gear 2 is connected to the supply device 1
Is supplied to the gear take-out section 3, and the positioning pin 4 is lowered by the lifting / lowering device 8 while protruding from the suction shaft 5 to ride on the gear 2. After sucking the gear 2 by the suction shaft 5, the gear 2 is lifted as it is, moved by the transfer device 7, lowered again by the elevating device 8, and floats when the tip of the positioning pin 4 hits the tip of the support shaft 9, and the gear 2 is supported. 9 is inserted up to the base. When the second and subsequent gears 2a are engaged with each other, the gears 2a are sucked in the same manner as described above, and then lowered while rotating the suction shaft 5 with the turning device 6. After the axial end faces of the gear 2 and the gear 2a come into contact with each other, if the gear 2a is rotated at least by the tooth pitch of the gear 2a, the gear 2a meshes with the gear 2 and the lifting / lowering device 8 reaches the lower limit and engages with the support shaft 9. Insertion is complete.

However, in such a method and apparatus, especially when the gear is made of metal, the burrs at the tip of the teeth are stuck during turning, making it difficult to align the teeth.
Also, if the gear is made of resin, if you forcibly turn it while pressing it, the tooth surface will be scratched and it will cause noise during gear movement, and it is also very difficult to match the phase of each gear, etc. There is a problem that the so-called gear tooth insertion insertion ratio and the phase alignment ratio are reduced, and the area productivity of the device is deteriorated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and provides a method and an insertion device for gear insertion which can improve the gear insertion ratio, the phase alignment ratio, and the area productivity of the device. The purpose is to provide.

[0007]

Embodiments of the present invention will be described below with reference to the drawings. Note that the same reference numerals are used for the same parts as those of the related art.

FIG. 1 is a perspective view schematically showing an outline of an insertion device capable of carrying out the method for inserting gears of the present invention.

In the figure, reference numeral 1 denotes a plurality of gear supply devices. 2 is a gear, 2p is a gear requiring phase matching, 3
Is a gear take-out portion provided in the gear supply device 1, 4 is a positioning pin of the gear 2, 5 is a suction shaft for sucking the gear 2, 7 is a transfer device, 8 is a lifting device, and 9, 9a are finally gears. 2,
A plurality of shafts into which a 2p is inserted and which constitute a power transmission mechanism using a plurality of gears, 10 is a tooth matching device, 11 is an image recognition device, and 12 is a rotation positioning device.

In order to finally assemble the power transmission mechanism using the plurality of gears, the gear tooth inserting / inserting apparatus is an apparatus which inserts the gears constituting the gear while aligning the gears with the support shaft. First, a plurality of gears 2 are successively supplied to a gear take-out portion 3 by a supply device 1, and a plurality of positioning pins 4 are lowered at once by an elevating device 8 while protruding from respective suction shafts 5. After the gear 2 is put on each gear 2, the gear 2 is sucked by the suction shaft 5, the gear 2 is lifted as it is, and is moved by the transfer device 7. In the meantime, the suction shaft 5 approaches the horizontal direction by the tooth matching device 10 and aligns with each other in accordance with the positions of the plurality of support shafts 9 to be inserted. The plurality of gears 2 with the gears are lowered at once by the lifting / lowering device 8, and when the tip of each positioning pin 4 hits the tip of each support shaft 9, the gears 2 float and the gears 2 are mounted on the support shaft 9. Inserted to the root,
The meshing insertion is completed.

As for the gear 2p which needs to be phase-matched, an image recognition device 11 is arranged on the gear take-out section 3 to calculate the difference from the angle at the time of completion of the tooth-matching, and to calculate the difference between the angle in advance. Then, the suction shaft 5a is rotated by the rotation positioning device 12, and thereafter, as in the case of the gear 2, after the descent, suction, and ascent, the rotation positioning device 12 is reversely rotated while being moved by the transfer device 7, and then the teeth are rotated. A plurality of gears 2
The gear 2p, which needs to be phase-matched, is geared, and the whole is inserted into the support shafts 9 and 9a to complete the process.

As described above, according to the present embodiment, a plurality of gears are respectively taken out from the supply device, are combined in the horizontal direction to perform tooth matching, and then are inserted into a plurality of spindles at once. , The gear tooth insertion rate has been improved,
