Abstract

PURPOSE:To enable the automatic assembly of a belt to pulleys in a narrow, part by pushing a belt held by the four pins of holding members in between pulleys utilizing its elasticity in a device for automatically assembling a rubber belt to said pulleys. CONSTITUTION:When a belt 1 is fed to holding members 2, 3, the whole assembly unit is lowered by means of a Z-axis air cylinder. Then, together with the rotation of a cam train 24, a Y-slider 18 slides and the belt is moved to pulleys 4, 5 side and passes the boss 23 of the pulley 4. Then, the holding members 2, 3 slides to the right and left to spread the belt 1. After that, the Y-slider 18 is moved again to introduce the upper part of the belt 1 onto the grooves of the pulleys 4, 5 with the lower part of the belt 1 left hooked on the boss 23 of the pulley 4. Here, a slider 6 is lowered by means of the cam train 24 and the lower part of the belt 1 is hooked to the downside of the pulleys 4, 5. Then, the holding members 2, 3 are retracted and the belt 1 comes off of finger pins falling onto the grooves of the pulleys 4, 5, thereby, completing assembling.

Description

Detailed Description of the Invention - [Field of Industrial Application] The present invention relates to a device for automatically assembling a rubber belt tractor to a pair of pulleys, and is particularly suitable for assembling a rubber belt to a pulley located in a narrow part of a product. The present invention relates to a belt assembling device.

[Conventional technology]

As shown in FIG. 6, the conventional device grips the belt 8 held by the chuck 7! The belt 8 is automatically mounted on the pulleys 9 and 10 by placing the belt 8 on the pulleys 9 and 10 and rotating or swinging the holders 11 to 13. However, this method requires a wide space around the goo IJ9.10 through which the belt 8 and the holders 11 to 13 can pass through at the same time, and especially the upper part of the side of the pulley must be completely open, i.e. When the other parts 14 are attached to overhang the side surface of the pulley 9 as shown in FIG. 4, or when the pulley 14 is attached as shown in FIG.
If it is installed in a state where it is sunk into the base 15, it is impossible to assemble it, and there are great restrictions on product design.

Note that related devices of this type include, for example, Japanese Patent Application Laid-Open No. 55-95251.

[Problem that the invention seeks to solve]

In the above-mentioned conventional technology, it was necessary to widely open the n-plane of the pulley and its surroundings, but applying this would place many restrictions on the product, especially when it comes to high-density mounting of components. This was a major hindrance, resulting in a decline in the competitiveness of products in terms of miniaturization. SUMMARY OF THE INVENTION An object of the present invention is to solve these problems and provide a belt assembling device that can perform a belt hanging operation even between pulleys mounted in a narrow space as long as there is a space through which the belt can pass.

[Means for solving problems]

In order to achieve the above object, the present invention has the following configuration. That is, the belt 1 is gripped by the gripper 2.3,
This is expanded and a part of it is pressed against the sides of the two pulleys 4.5 and guided to the upper part of the groove of the other t pulley (.After this,
Push the side of the belt 1 that is pressed against the side of the pulley, and pull each pulley 4°50 to one side. Next, the grip on the side that has already been guided to the upper part of the pulley groove is released and the belt 1 is dropped into the pulley groove, completing the work of assembling the belt to the pulleys 4 and 5.

[Effect]

The thickness of the slider that slides along the side of the pulley is sufficient if it is equal to the thickness of four belts, and therefore, the belts can be assembled as long as there is a space through which the belts can pass.

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5.

In the same figure, a Y slider 18 that slides in the Y direction is mounted on a base 17 that is integrated with a two-axis slider 16 that slides in the Z-axis direction, and furthermore, two left and right sliders that slide in the X direction are mounted on the base 17. There are two X sliders 19.21. At the tips of these X sliders, there is a left gripping tool 2. There is a right gripping tool 3, and the belt 1 is gripped between four finger bins 21 provided on the right gripping tool 3. On the other hand, the slider 6 is
The product slides on a guide 24 provided on the base 17 along the side surfaces of the pulleys 4 and 5, but in this embodiment, one pulley 4 of the product is provided with a boss 23. 6 is provided with a corresponding U-shaped relief. And these Y sliders 18. The left and right X sliders 19, 20 and the slider 6 have a structure in which they are each driven by rotating the cam row 24.

Next, the operation will be explained using FIG. 2. In FIG. 2, first, ■When the belt 1 is supplied to the grippers 2 and 3,
(2) The entire assembly unit is lowered by the two-axis air cylinder 25. The Y slider slides as the 0th cam rotates,
The belt 1 is moved to the pulley side, and the boss 25 of the pulley 4
pass through. ■Subsequently, the grips A2.5 slide to the left and right to expand the belt 1, and then the Y slider 1B is moved again.
moves and guides the belt top S onto the grooves of the two pulleys 4 and 5 while keeping the lower part of the belt hanging on the pulley boss 23 (.

(2) At this point, the slider 6 is lowered by the cam, and the lower part of the belt is pushed by the slider 6 and hooked onto the lower side of the pulley 4.5.

(2) Next, the gripper 2.5 retreats, and the belt 1 is detached from the finger bin 21 and falls into the groove of the pulley 5, completing the assembly. ■The entire assembly unit rises, and the workpiece receiver returns to the position of picking it up.

In this example, four bottles are provided as belt gripping tools with a gap slightly smaller than the belt thickness, and the structure is such that the belt is pushed in and gripped using the elasticity of the belt, so the chuck There is no need to open or close the slider, and the grip can be released simply by retracting gripper A while the slider is lowered by 6%. Also, the series of assembly operations is performed by a cam, which speeds up the assembly work. planned,
It has a great effect on reducing man-hours.

Figure 3 is Ki-ni F! FIG. 2 is a diagram showing the basic configuration of an AK device and its sequence.

〔Effect of the invention〕

According to the present invention, it is possible to assemble a belt in a narrow area, which has been difficult to automate up to now, for example, as shown in FIG.
If part of the part is covered by other parts 14,
Alternatively, even if the Gooley knife 0 is installed by sinking into the base 15 as shown in Figure 5, automatic assembly of the belt is possible as long as there is a gap through which the belt can pass, allowing for high-density mounting of parts and products. Can be converted into a hut.
