Rotation Ratio Variable Power Train {A speed change gear apparatus}

The present invention is connected to the main shaft and the driven shaft, the rotation ratio is controlled by the user's operation, and relates to a power transmission device for the feed amount of the object to be transferred by the rotation of the driven shaft, in particular the main shaft and the driven shaft Since the range of rotation ratio that can be deformed by the user's operation is infinitely wide because it is connected by the zero-roll method, it can be used in various devices such as a device for precisely controlling the amount of conveyed object and a device requiring a large change in the amount of conveyance. It relates to a rotation ratio variable power transmission device.

In general, the power transmission device is installed between a main shaft connected to an engine or a motor and a driven shaft through which power is transmitted from the main shaft, so that the driving force suitable for the final driving body is transmitted by converting the driving direction of the driving force or converting the rotational speed thereof. As an apparatus to be used, a description will be given of only the power transmission apparatus which can reduce or decrease the rotational speed of the roller for conveying the filter in the cigarette filter manufacturing apparatus.

There are many types of variable speed transmission power transmission devices according to the prior art, but in general, a plurality of various gears are installed on a driven shaft, such as a transmission mounted on an automobile, and the driven shaft is installed to be movable in the axial direction. There is a power transmission device whose rotation ratio is determined according to the gear of the coaxial shaft and the driven shaft being meshed.

In addition, unlike the power transmission device described above, a spline gear in which the peak of the gear is formed long in the axial direction is installed on the output shaft, and a helical gear is installed to move in the axial direction along the spline gear to connect the input shaft and the output shaft. There is a device.

However, in the case of a power transmission device in which the rotational speed variable power transmission device according to the prior art has a plurality of gears installed in the driven shaft, the speed ratio is converted in stages because the rotation ratio is converted according to the dimensions of the gear installed in the driven shaft. As a result, there is a problem in that the fine speed ratio cannot be converted.

In addition, in the case of the power transmission device in which the spline gear and the helical gear are installed, since the range in which the helical gear slides along the spline gear is limited to a predetermined length, speed conversion over a predetermined value cannot be performed and thus cannot be installed in various devices. There is a problem.

The present invention is devised to solve the above-mentioned problems of the prior art, and is installed to control the rotation ratio by the user's operation bar bar, the planetary gear is installed so as to rotate 360 ° around the sun gear, It is an object of the present invention to provide a variable rotation speed transmission device that can be installed in a variety of devices that require precise conversion ratio conversion or wide rotation ratio conversion because the range of the conversion ratio is infinitely wide.

Figure 5 is a perspective view showing the inner skin of the tobacco filter manufactured by the tobacco filter manufacturing apparatus to which the present invention is applied, Figure 6 is an exploded perspective view of the tobacco filter manufactured by the tobacco filter manufacturing apparatus to which the present invention is applied.

The crimping acid 75a is formed while maintaining a predetermined interval on the circumferential surface of the crimping roller 75 as shown in FIGS. 2 and 3, and the crimping roller is formed because the flat portion 75b is formed at the interval. Endothelial 56 passing through 75a is also formed with a certain length of wrinkles 56a, and a marginal portion 56b without wrinkles is formed regularly.

The margin part 56b becomes a part to be cut by the cutter 84 when the filter is later cut by the cutter 84 to a certain length, and the cutter 84 is the center of the margin part 56 (M).

Looking at the operation of the present invention is configured as described above applied to the cigarette filter manufacturing apparatus as follows.

First, when power is applied, the first, second, and third supply devices are driven to transfer the fibers 52, the outer shell 54, and the inner shell 56 to the winder 80, and then the outer shell 54 and the inner shell 56. ), The fibers are stacked in order, and the cross-sectional shape thereof is wound so as to form a circle having the same diameter as that of the pistol portion, so that the circumferential end of the shell is finished, thereby forming a filter.

At this time, the endothelial wrinkles (56a) is formed while maintaining a predetermined distance in the longitudinal direction by the crimping acid (75a) while passing through the crimping roller (75), the space between each of the wrinkles (56a) The part 56b is formed and supplied.

Subsequently, the filter is continuously transferred to the cutter 84 and the cutting center of the margin 56b is cut by the cutter 84 performing a cutting operation while maintaining a constant time difference, thereby completing a tobacco filter connected to the pistol. .

If the operation as described above is repeatedly performed for a long time, the error that the position off the center of the margin 56b is cut due to various reasons, such as the play between the gears or the error of the transfer devices, such as In this case, when the user operates the lever 44, the rotation ratio variable power transmission device is driven by the lever to control the rotational speed of the crimping roller 75, so that the feed amount of the endothelial 56 is adjusted so that the filter is cut.
