Description

Automatic balance balance device for left and right tension of fabric using roller

The present invention relates to an automatic balancing device for left and right tension of a fabric to be conveyed using a roller, and more particularly, to install the tension balancing roller between the inlet and the outlet of the fabric to be conveyed from a roll or a continuously fed device. The left and right tension of the fabric applied to the roller is maintained using the seesaw principle to prevent the advancing direction of the fabric from being distorted, and also the advancing and exiting sections of the roller do not have to be horizontal. Bearing guides are installed in the housings of the left and right ends of the rollers to maintain the constant energy, so that the left and right tensions can be uniformly matched without the use of the auxiliary roller even in the advancing direction of the fabric. It relates to a right and left tension automatic balancing device.

In general, as a product using paper and plastic fabric, packaging boxes for safe packaging of various items such as electronic products, foodstuffs, glass products, etc. are widely used. Manufacturing is accomplished by automated production lines that go through several stages of processing equipment to cut or join.

In such an automated production line, a feed roller for the continuous and uniform supply of paper fabric is inevitably used, and this fabric is subjected to the joining process according to its processing process or trimmed and cut according to the standard to produce the required product. In the manufacturing process, various types of apparatuses and methods are used to prevent warpage of the fabric during warping and warping due to bonding.

Twisting that occurs during the progression of the fabric is usually done by using several rollers while the tension is maintained, or by installing a roller equipped with a device that can be moved at one end of the rollers. Although it is using a method that can be corrected, it requires complicated and skilled workers to set up each time according to the type of fabric, and the warpage of the fabric is similarly adjusted by hand by manually adjusting the position of the roller shaft or the amount of roller. The tension is controlled by attaching a spring to the end, but the effect is not obtained very much.

In addition, the twisting phenomenon that occurs from the direction of fabric movement occurs because the left and right tension of the fabric conveyed from the supplying device is not constant, and the tension is oriented toward the larger direction depending on the deviation of the right and left tension while contacting the feed roller. It can be seen that the warpage phenomenon is also caused by the distortion of the left and right tension after the completion of the joining is completed in the state that the two sides have different tension when joining two or more different fabrics. Not only is it difficult to maintain product quality or specifications, but it is also a major factor in increasing the defective rate.

In order to prevent such a problem, the left and right tension of the conveyed fabric is kept constant and enters the next process step. Conventionally, according to the tension, the position of the roller shaft is manually adjusted, or springs are attached to both ends of the roller or half moon. Although the tension is controlled by a structure such as a rack and a pinion, it is not possible to precisely control it because it is controlled by a worker's manual work, and it takes a lot of working time.

In addition, although the tension adjusting device by a spring or the like is installed on the axis of the transfer roller, it is very complicated in structure and expensive to install, and when the width of the fabric is small compared to the axial length of the roller due to the repulsive force caused by the spring There was a problem that the fine tension can not be adjusted.

On the other hand, in order to solve this problem, the automatic adjustment device of the tension of the transfer roller No. 20-0396131 for registration room has been devised, which is coupled to the shaft formed on both ends of the transfer roller and the upper surface of the transfer roller for transferring various sheet paper fabric A connecting member having a central roller connected to each other so as to rotate with the shaft on one side, and having a balance roller installed on the other side to rotate with an idle and parallel to the central roller; Longitudinal direction to form a center guide hole to the center roller is coupled to, and the balance adjustment guide ball to form a horizontal direction on one side is coupled to the balance roller consists of a pair of supporting members formed symmetrically with each other.

In the prior art of such a configuration, by using the seesaw principle the tension applied to the feed roller of the roll-type fabric is always uniform left and right tension to significantly reduce the phenomenon that the fabric is stretched or shrunk and to combine the fabric and heterogeneous fabric When laminating (laminating) work, the warp phenomenon that the fabric is irregularly bent or distorted is significantly reduced, thereby improving the quality of the product and reducing the defective rate of the product.

However, in the prior art, it is inconvenient to adjust the horizontality of the center roller and the balance roller first.

In addition, since the center roller is moved up and down only in the vertical direction with respect to the support member, when the position energy of the left and right support shafts is changed, the tension of the feed roller due to the seesaw principle is not smoothly adjusted.

It is an object of the present invention to provide an automatic balance adjustment device for the left and right tension of a fabric using a roller that allows the feed roller shaft to flow in various angles as well as in the vertical direction.
