Description

Detailed Description of the Invention

The present invention relates to a continuous belt for use in an apparatus for feeding free flowing material at high speed.

The present invention provides a free-flowing material in a receiving space that separates a filter plug as the plug moves over a conveyor (such a conveyor is referred to in the tobacco manufacturing art as garniture tape). The present invention relates to a laminated belt used in the device.

According to a second embodiment, the invention comprises a pair of parallel endless belts with hanging rows of units called pockets. It is particularly useful for supplying free flowing material in the manufacture of cigarettes. The present invention, as the plug travels on the conveyor (in the tobacco manufacturing art, such conveyors are referred to as garniture belts), the free space, such as charcoal granules, in the receiving space separating the filter plugs. Used in equipment for supplying flowable materials.

Some prior art devices for inserting free flowing material between filter plugs use belts. For example, U.S. Pat. No. 4,285,678 includes a belt. The belt travels around multiple wheels. During some portion of this movement, the belt travels along and parallel to the garniture tape. The garniture tape carries an axially aligned row of filter plugs separated by a receiving space for movement of the filter plugs between the garniture tape and the belt. The belt includes apertures aligned with the receiving space separating the filter plugs. These apertures guide the free-flowing material into the receiving space. The blank portion of the belt covers the filter plug from exposure to free-flowing material.

Similarly, US Pat. No. 3,464,324 includes a belt that travels over a row of filter plugs that are moved over garniture tape (referred to in this patent as moving inclusion tape). .. Granular material passes through the apertures in this belt and is deposited in the space between the plugs. The apertures in the belt are timed to match the receiving space between the filter plugs.

Similarly, US Pat. No. 3,464,324 includes another embodiment which utilizes linked chains. The chain includes a web portion with an elongated groove that allows the granular material to pass into the cavity separating the filter plugs.

Some prior art devices, including those described in US Pat. No. 3,623,404, include belts or chains of rows of endless links. In such a device each link is connected to a preceding and a following link to form an endless chain. The chain travels around multiple wheels or sprockets to drive it, tension it, and hold it in place. The chains are spaced apart in space and are axially aligned and move in part parallel and adjacent to the garniture tape that carries the row of filter plugs.

Links including such chains are provided with channels or funnels through which the particulate matter can flow. As the chain and garniture tape move parallel to each other, the links move adjacent to the axially aligned filter plugs. During this adjacent movement, the funnel in the link aligns with the space between the filter plugs and the distributor supplies particulate matter to the funnel in the link. The funnel flushes this granulate into the adjacent receiving space.

Belts in the prior art serve to cover the filter plug from exposure to free-flowing material. However, these belts do not hold the filter plug in a stable position on the garniture tape as it advances at high speed.

Currently utilized chains suffer losses resulting from tolerances due to the connections between their respective links. Losses resulting from connection tolerances result in varying distances between links, causing varying distances between apertures in the links. Due to this variation, the apertures running parallel to and adjacent to the receiving space cannot maintain alignment with said space. This discrepancy between the aperture and the receiving space causes an incorrect feeding of the particulate matter.

It has been desired to provide laminated belts for use in devices that supply free-flowing material into the receiving space between filter plugs.

Further, it has been desired to accurately feed free-flowing material into the receiving space between filter plugs that move at high speeds over garniture tape.

Furthermore, there has been a desire to protect filter plugs from exposure to free flowing materials.

The present invention, in one embodiment, provides a belt that is laminated with a metal band and a component strap. The laminating belt travels around a plurality of wheels on a path that is partially parallel to and adjacent to the path of the garniture tape that carries the axially aligned filter plugs. The construction strap follows the round shape of the filter plug carried by the garniture tape. During their translation, the laminated belt garnishes the filter plugs.
Press on the tape to hold the plug in place.

A plurality of apertures extend through the belt. Independent means synchronize the movement of the laminated belt with the movement of the garniture tape so that the apertures through the belt are aligned with the receiving space between the filter plugs. Similarly, the blank part of the belt matches the filter plug,
Shield the filter plug from exposure to free flowing materials. By pressing the plug against the garniture tape, the laminating belt ensures that the plug holds the plug in this aligned configuration. A device known in the art, a charcoal chute, feeds particulate matter through apertures in the belt and into the receiving space separating the plugs.

By holding the filter plug firmly against the garniture tape, this laminated belt allows the open area of the belt to be received against the receiving space, even when the garniture tape moves the plug at high speed. Keep it up. Such stable alignment allows accurate delivery of free-flowing material even at very high speeds,
Laminated belts, on the other hand, shield the filter plug from exposure to free flowing materials.

It has also been desired to accurately feed free-flowing material into the receiving space separated by axially aligned filter plugs as the plugs move over the garniture tape at high speeds. ..

Furthermore, it has a hanging pocket,
It has been desired to have a device that includes parallel belts for supplying free flowing material in the receiving space between the filter and plug.
