Abstract

PURPOSE:To prevent a gear from being damaged, and to aim at simplifying the operation of an automatic gear assembly device, by attaching an air nozzle to a hand, and by blowing air from the air nozzle to obtain a rotary motion for engaging gears with each other. CONSTITUTION:When a hand section 3 of a conveying means 6 is located above a gear 2 at the front end of a chute 7, pawls 8 are opened, and then the hand section 3 is lowered onto the gear 2 in association with the operation of a cylinder 13 so that the pawls 18 grips the gear 2. Further, the hand 13 comes to a stop above a gear shaft 16 of a mechanical part 14, and is lowered so that the gear 2 is fitted onto a shaft 6. Accordingly a gear already fitted onto the shaft and the gear 2 fall into an engaging condition. When air from an air nozzle provided on the hand 3 is blown onto the tooth section of the gear 2, the gear 2 is rotated so that it is released from the gear 1 and falls into a meshing condition. Therefore, the gear 2 is dropped to be completely fitted onto the shaft 16. With this arrangement, the gears may be assembled in a simple operation without the gears being damage.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field of the Invention) The present invention relates to an automatic gear assembly device for assembling gears into equipment components such as machine tools so as to mesh with each other.

[Technical background of the invention and its problems]

Automatic gear assembly equipment is generally assembled by manually gripping a gear supplied from a feeder, fitting it onto the gear shaft of the equipment, and rotating this gear so that it meshes with another gear already attached to the equipment part. is being carried out.

FIG. 4 is a perspective view of a conventional example for performing this meshing. A claw 22 that can be opened and closed is attached to the lower surface of the hand 21, and is adapted to grip a gear 23. hand 21
is controlled to be movable as appropriate, and by movement of the hand 21, another gear 2 already attached to a device part (not shown) is moved.
The gear 23 is fitted to a gear shaft adjacent to the gear shaft 25 of No. 4.

A lever 26 that can come into contact with the gear 23 protrudes forward from the hand 21 so as to impart rotational motion to the gear 23.

When the gear 23 is to mesh with another gear 24 by this attachment, the gear 23 held by the claw 22 of the hand 21
3 is fitted into a predetermined gear shaft, and then the -hand 21 is moved laterally in the direction of the arrow in FIG. With this horizontal movement, lever 2
6 hits the gear 23 and rotates the same gear 23 in the direction of arrow B.

This rotation causes the gears 23 and 24 to mesh with each other, and the assembly work is completed.

Therefore, according to the conventional device, the hand 21 needs to move laterally in order to rotate the gear 23, and the operation of the hand 21 is complicated and difficult to control, and it takes a long time to assemble. Further, since the lever 26 contacts the tooth if 23, the gear 23 is easily damaged and the lever 26 is also easily broken.

[Purpose of the invention]

The present invention was made in order to solve the above problems, and an object of the present invention is to provide an automatic gear assembly device that can mesh gears with a simple operation and does not damage the gears. .

[Summary of the Invention] In order to achieve the above object, an automatic gear assembly device according to the present invention is provided with an air nozzle attached to the hand, and a rotational movement that causes the gears to mesh with each other by blowing air from the air nozzle. Features.

[Embodiments of the invention]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The automatic gear assembly apparatus according to the present invention will be specifically described below with reference to illustrated embodiments.

FIG. 1 is an overall perspective view of an embodiment of the present invention, and FIG. 2 is a perspective view of the hand portion in an assembled state.

A feeder 5 that continuously supplies gears 12 is disposed on a base 10, and a chute portion 7 that extends linearly is formed at an upper end portion of the feeder 5. The chute section 7 is inclined so as to gradually move downward toward the tip, and the gears 12 fed to the feeder 5 are sent out to the chute section 7 in order and slide down under their own weight, so that the gears 12 are sequentially arranged in a row from the tip of the chute section 7. They are now aligned. A conveyance means 6 is arranged on the left side of the feeder 5, and a hand 3 is attached to the conveyance means 6. In the conveyance means 6, a guide 6b is hung horizontally between the left and right legs 6a, and a slider 6C is attached to the guide 6b so as to be slidable in the longitudinal direction. The slider 6C slides by having its left end hooked onto a belt 6d, which is rotated by the drive of a motor (not shown).

The hand 3 is attached to the slider 6C of the conveying means 6. In this embodiment, the hand 3 is attached to the lower end of a rod 13a of a cylinder 13 fixed to a slider 6C, and is moved up and down by driving the cylinder 13. A pair of left and right claws 8 that are driven to open and close extend from the lower surface of the hand 3, and the opening and closing operations of the claws 8 grip and release the gear. Further, an air nozzle 9 is attached to the hand 3, as shown in FIG. This air nozzle 9 is connected to an air supply source (not shown) such as an air pump, and its tip is bent in the direction of the claw 8 so as to spray air onto the gear 2 held by the claw 8. . This blowing of air imparts a rotational motion in which the gear 2 meshes with the gear 1, as will be described later.

Equipment parts 1 assembled so that gears mesh with each other
4 is positioned at a predetermined position on the base 10 by appropriate positioning means (not shown) provided within the sliding range of the slider 6C. In FIG. 1, two parallel gear shafts 15 and 16 are erected on the upper surface of the equipment component 14, and the gear 1 is fitted into one gear shaft 15, and the gear 2 is fitted into the other gear shaft 16. It is designed to be fitted.

Next, the operation will be explained. Gears are aligned in a chute portion 7 formed on the feeder 5. When the conveyance means 6 is driven and the hand 3 is positioned above the gear 2 at the tip of the chute section 7, the pawl 8 opens and the hand 3 is lowered onto the gear 2 by the operation of the cylinder 13. Next, when the claw 8 closes and grips the gear 2, the hand 3 is raised by the reverse operation of the cylinder 13. Then, the hand 3 gripping the gear 2 is moved above the equipment component 14 by the drive of the conveying means 6, and stops directly above the gear shaft 16. This stop activates the cylinder 13, lowers the hand 3, engages the gear 2 held by the claws 8 onto the gear shaft 16, and then the claws 8 open to release it from the gripped state.

FIG. 3 is a front view showing such a state, in which the teeth of the gear 2 come into contact with the teeth of the gear 1 already fitted into one gear shaft 15 of the equipment part 14, and are in a floating state.

Here, as shown in FIG. 2, air is ejected from the air nozzle 9, and the gear 2 is blown with air. As a result, the gear 2 rotates around the gear shaft 16, and due to the rotation, the state of engagement with the teeth of the gear 1 is released and meshes with the teeth ill.

Therefore, the gear 2 falls under its own weight and is inserted into the gear shaft 16. Therefore, since there is no need to move the hand 3 laterally to rotate the gear 2, the operation becomes simple and control becomes easy. Furthermore, since the gear 2 is rotated by blowing air, the gear 2 will not be damaged.

In addition, in the present invention, if the chute portion of the feeder and the equipment component are at the same height, the cylinder for raising and lowering the hand can be omitted. Further, the conveyance means may be constituted by a cylinder.

〔Effect of the invention〕

As described above, according to the present invention, the rotational movement for interlocking the gears is performed by blowing air from an air nozzle, which simplifies the operation and facilitates control, while also preventing damage to the gears. An automatic gear assembly device that can perform the following operations is obtained.
