Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an emery raising device that raises or straightens the surface of cloth by polishing to obtain products with suede, flannel, velvet, or the like.

Although emery-type napping devices have been widely used in the past, it is considered to be a field of processing technology that requires advanced technology and experience.
This is an emery process that not only cannot be reprocessed if raised spots or defects such as reduced strength occur.
This is because there is a possibility that the product cannot be used even after crushing. For this reason, there has been a strong demand for an apparatus capable of uniform emery raising. These measures include creating a device that can draw out the fabric uniformly, equalizing the contact pressure between the fabric surface and the emery roll, and preventing abnormal tension, but currently none of these items are effective. There is no satisfactory device or proposal that incorporates this.

The present invention was made in view of the current situation, and
The object of the present invention is to provide a device that incorporates all of the above items and is capable of uniform, high-quality emery raising.

That is, the present invention provides an emery raising device equipped with one or more emery rolls that rotate in the opposite direction to the direction in which the cloth travels. A large number of cloth drawer cylinder rolls are installed in the cloth drawer part to perform the pull-out drive by the cloth drawer, and secondly, contact angle adjusting rolls are installed between each emery roll and for adjusting the degree of contact between the cloth surface and the emery roll surface. / Or a vertically movable device is installed between the emery roll and the guide roll, and thirdly, the fabric tension is adjusted to adjust the contact pressure between the emery roll and the fabric surface by moving two guide bars. A rotatable fabric tension adjustment guide bar consisting of two bars is provided just before the emery roll to adjust the tension by changing the resistance force. This emery raising device is characterized in that a pair of forced cloth feed rolls and a cloth timing section are attached to the cloth entrance section of the emery section, and according to the method of the present invention, uniform emery raising can be easily and stably performed. .

The present invention will be described in detail below with reference to the drawings.

FIG. 1 is a side view showing the main parts of the device of the present invention. In the drawing, the cloth 1 is fed by a delivery roll 2,
2', the cloth is fed in one roll from a cart or batch roll (not shown) to the cloth timing device 3. Next, the fabric 1 passes through the guide roll 4 located above the fabric timing device 3, and then passes through the guide roll 5, the tension adjustment guide bar 6, the emery roll 7, the contact angle adjustment roll 8, the emery roll 7', and the contact angle adjustment roll 8. The surface of the cloth 1 is raised while passing through the angle adjustment roll 8', the emery roll 7'', and the contact angle adjustment roll 8'' in sequence. The brushed cloth 1 is transferred to the cloth drawer cylinder roll 1 next to the guide roll 9.
After being pulled out by 0, 10', 10'', 10,
It is shaken off by a shake-off roll 11 onto a truck or a timing device (not shown).

Since the emery raising device of the present invention uses an emery roll that rotates in the opposite direction to the direction in which the cloth travels,
The conveyance drawer of the cloth has a large influence on the uniformity of the emery raising, and if the cloth conveyance drawer has unevenness, a horizontal step-like defect will occur on the raised surface of the cloth. This is because when the fabric is conveyed intermittently, the emery rotates in contact with it for a long time at the same position, and because the contact pressure to the emery roll changes due to changes in tension. In the apparatus of the present invention, a large number of drawer cylinder rolls are provided, and the drawer is driven by frictional resistance between the surface of the drawer cylinder rolls and the cloth surface. Further, if necessary, the surface of the cloth draw-out roll may be lined with soft rubber, wrapped with a sponge plate or tape, or wrapped with urethane film or coarse cloth. In the apparatus of the present invention, the surface speed of the cloth drawing cylinder rolls 10, 10', 10'', and 10 is the cloth processing speed.Needless to say, the raising effect has an important relationship with the cloth processing speed, and it is possible to reproduce a certain quality. In order to obtain a raised product with good properties, it is necessary to keep the cloth processing speed, that is, the rotation speed of the cloth drawer cylinder roll, constant.The diameter of the cloth drawer cylinder roll is usually about 30 to 60 cm.Next, the cloth surface contact angle adjusting rolls 8, 8', for adjusting the degree of contact between the emery roll and the surface of the emery roll;
8'' is installed between the emery rolls 7, 7', 7'' and the guide roll 9. The number of emery rolls may be one or two, but in order to improve productivity, the number of emery rolls is three or more, usually 3 to 10, and 3 to 5 is particularly efficient. If the number of emery rolls and contact angle adjustment rolls increases, the tension applied to the cloth will increase, causing deformation of the cloth and making adjustment complicated, making it difficult to obtain uniform napping and reproducibility. In the drawing, by lowering the contact angle adjusting rolls 8, 8', 8'', the contact area between the cloth and the emery rolls 7, 7', 7'' increases, thereby improving the napping effect of the cloth. but,
On the other hand, since the tension applied to the cloth increases, if the cloth should not stretch too much, the contact angle needs to be adjusted appropriately.
8', 8'' have a structure that allows them to be fixed at any appropriate position during the napping process.In addition, it is better for the contact angle adjustment rolls 8, 8', 8'' to rotate freely upon contact with the fabric 1. This is preferable because the tension applied to 1 is reduced. The emery rolls 7, 7', and 7'' usually have a diameter of about 10 to 30 cm, and are designed to be wrapped with tape having a sandpaper grain size of about 120 to 250.

2 to adjust the contact pressure between the emery roll and the cloth surface.
This is done by changing the contact resistance force with the cloth 1 by rotating and moving a rotatable cloth tension adjustment guide bar 6 made of a book bar, but the raising effect can be improved by increasing the contact pressure between the emery roll and the cloth surface. However, the tension applied to the cloth becomes large, causing the disadvantage that the cloth 1 deforms or wrinkles occur, so it is necessary to set the position of the tension adjustment guide bar 6 to the lowest tension that does not cause raised unevenness. What is more important is to prevent abnormal tension, and in the present invention, in order to prevent this abnormal tension and always maintain a constant tension, forced cloth delivery rolls 2, 2' are installed at the cloth entrance in front of the cloth tension adjustment guide bar 6. A cloth timing device 3 is also installed. When the fabric 1 is directly passed from the cloth transporting trolley or winding roll to the cloth tension adjustment guide bar 6, when the overlapped fabric in the cloth transporting trolley is pulled out from inside the trolley or when it is pulled out from the winding roll. When the tension changes, the tension adjustment guide bar 6
Even if the emery roll is attached, the contact pressure between the emery roll and the fabric changes, resulting in the occurrence of raised spots, which is caused by the fabric being conveyed intermittently as the tension changes.
Therefore, in the present invention, a cloth timing device 3 is provided to eliminate this drawback. What is important here is the state in which the fabric is timed by the fabric timing device 3, but it is meaningless if the fabrics overlap each other as in the fabric transport trolley. The timing of the cloth 1 sent out by 2' is such that the cloths do not overlap each other. The method of processing the emery nap most uniformly and with high reproducibility is to pass through the guide roll 4 provided above the cloth timing device 3, pass through another guide roll 5, and then connect to the tension adjustment guide bar 6.

As the present invention has been described in detail above, even if any of the above-mentioned configurations is omitted, uniform emery raising is not guaranteed. The present invention exhibits great effects by combining known simple devices, and has been able to overcome the conventional drawbacks such as emery fluffing, reduced strength, and poor reproducibility.

Additionally, if necessary, additional equipment can be installed such as a brushing device for removing lint, a drying cylinder device for cloth that has been left unused for a long time, a heating cylinder device for removing pile wrinkles, a dust collector, etc. There is no problem in providing an electrostatic device or the like as long as it does not impair the operation and effects of the present invention.
