Description

Cloth winding device

The present invention relates to a cloth winding device for opened out knitted fabric webs and tubular knitted fabric webs, which includes a vertical axis of rotation, which can be knitted with an endless loop The axis of rotation of the machine is arranged coaxially.

For example, it is known from EP 1 808 518 B1 that a tubular knitted fabric net produced by an endless knitting machine can be directly or in an open state (ie after the tubular fabric is cut and opened) using this cloth winding device It is wound onto a flat web of goods. If you want to change from one type of reel to another, it is only possible after the cloth winding device is properly switched.

Since the cloth winding device is also accommodated in the cylindrical outer cover of the circular knitting machine, the maximum possible diameter of the bale of the knitted cloth being wound is limited due to space reasons. This is especially a disadvantage when winding tubular knitted fabrics, because after about half the length of the mesh, the double-layer needle The woven mesh has created the same bundle diameter as when winding the open knitted mesh.

The object forming the basis of the present invention is to provide a cloth winding device for an endless knitting machine, so that when winding a tubular knitted fabric web, a larger maximum winding diameter can be obtained than a conventional cloth winding device.

The object of the present invention is achieved by the aforementioned kind of cloth winding device, characterized in that the tubular knitted fabric can be wound onto the winding rod at a horizontal position farther from the vertical rotation axis than the opened knitted fabric.

In the case of the conventional cloth winding device, the winding rods for the opened knitted fabric net and the tubular knitted fabric net are arranged at the same position of the apparatus, or the common winding rod is used for both knitted fabric nets. The knitted fabric bundle formed from the tubular knitted fabric is shorter than the one formed from the opened knitted fabric. On this basis, a shorter winding rod can be used for these knitted fabrics and can be wound in the cylindrical outer cover of the knitting machine more outward than the opened knitted fabric. There is also more room in the vertical direction in the periphery of the outer cover than near the middle axis of rotation. These spatial conditions are used in the case of the cloth winding device according to the present invention. Displacing the winding rod for the tubular knitted fabric net to the outside enables these two-layer fabric nets to achieve a significantly larger bundle diameter compared to the cloth winding device according to the conventional technology.

The tubular knitted fabric can also be wound on a winding rod in another vertical position, which is preferably deeper than the opened knitted fabric, to further optimize the use of the available space in the outer cover of the knitting machine .

In the first preferred configuration of the cloth winding device, two Separate winding rods are provided for the opened knitted fabric web and the tubular knitted fabric web, which can be selectively inserted into the cloth winding device. The winding rod for the tubular knitted fabric can be selected to be shorter than the winding rod for the opened knitted fabric, and as a result it can be located relatively far outside if the spatial conditions are more favorable in the area perpendicular to the axis of rotation .

If the cloth winding device has a cheek, the cheek includes a bearing groove at the end of the winding rod for the open knitted fabric, and the winding rod at the opening for the knitted fabric is moved After the removal, the cheeks of the bearing grooves with different guides can be installed between the bearing grooves for the winding rod of the tubular knitted fabric, another advantageous result can be achieved. The proper configuration of the bearing groove can achieve the best position for the two winding rods established in the outer cover of the knitting machine.

In the case where the bearing groove can have a horizontal section, it extends as far as the front end of the cheeks, so that the winding rod and the wound knitted fabric can be removed forward from the device.

Preferably, the cheeks of the winding rod for the tubular knitted fabric can be adjustably spaced from each other. This then allows winding rods of different lengths to be arranged in the cheeks of tubular knitted fabrics of different diameters.

In an alternative configuration of the cloth winding device, a common winding rod for the open knitted fabric and the tubular knitted fabric can be provided, and the end of the rod can be provided in the bearing groove for the tubular knitted fabric The difference is used in the bearing groove of the open knitted fabric.

However, due to the necessary length of the winding rod in this variant, when using a shorter winding rod for the tubular knitted fabric, the winding rod has no Law moves far to the outside.

It is also advantageous that if the winding rod or the winding rods can be driven by a shaft, the shaft is engaged on the outer periphery of the knitted fabric bundle being wound, and the shaft and the inner The winding rods are set to rotate together. This shaft simultaneously presses the knitted fabric against the pre-wound layer and thus ensures that no creases can be formed during the winding process.

If the ends of the winding rods are respectively arranged in bearing grooves in a floating arrangement, it is also advantageous if the bearing grooves have upwardly sloping sections on a linear or curved path, where these windings The end of the rod moves upward with the increased thickness of the knitted fabric bundle, with the shaft engaged on the lower outer peripheral section of the knitted fabric bundle. The friction between the winding rod with the bundle and the shaft is then further promoted by the gravity of the bundle.

The upwardly inclined section of the bearing groove may also have multiple linear sections at different angles from the horizontal. In addition, the section inclined upwards can preferably be combined with the horizontal running section, and the device can be automatically cut off by reaching the horizontal section through the end of the winding rod. The knitted fabric bundle can then be easily removed from the device by removing the winding rod from the horizontal section of the bearing groove.

To this end, the cloth winding device may have a cheek, on which the bearing block can be selectively arranged with bearing grooves of different guides for winding the end of the winding rod of the tubular or open knitted fabric web .

In this case, the position of the winding rod for the tubular knitted fabric according to the present invention can be achieved by: the upwardly inclined section of the bearing groove of the cheek of the winding rod for the tubular knitted fabric Than the needle used to open The upwardly inclined section of the bearing groove of the cheek of the woven mesh winding rod operates at a flatter angle and/or longer length. The end position of the winding rod is therefore placed further away from the axis of rotation of the winding rod for the open knitted fabric and/or the end position of the winding rod for the open knitted fabric Deeper.

The present invention will be described in more detail on the basis of the preferred exemplary embodiment of the cloth winding device.

The winding rod 11 for the knitted fabric 12 opened is inserted into the cloth winding device 10 as shown in FIG. 1. End system of winding rod 11 It is arranged in the bearing groove 1 of the side cheek 13 of the cloth winding device 10. As particularly indicated from the side view of FIG. 2, the bearing groove 1 has an upwardly inclined section 1.1 and a horizontal section 1.2. When the knitted fabric bundle 14 for the opened knitted fabric web 12 has the largest possible diameter as shown in FIG. 2, then the end portion of the winding rod 11 is at the horizontal section 1.2 of the bearing groove. The horizontal section 1.2 of these bearing grooves is opened forward so that the winding rod 11 can be removed from the cloth winding device 10 in the direction of arrow 15 together with the knitted cloth bundle 14.

The maximum possible diameter of the knitted fabric bundle 14 is limited by the cloth guide roller 16 which is arranged above the horizontal section 1.2 of the bearing groove 1. In this position, the winding rod 11 is at a distance A from the vertical axis of rotation D, which is oriented coaxially with the axis of rotation of the circular knitting machine (details not shown here). Due to the arrangement of the cloth winding device 10 in the cylindrical outer cover of the endless knitting machine and the need for the winding rod 11 of the knitted fabric web 12 to be sufficiently long, the distance A may increase. The winding rod 11 must be positioned relatively close to the axis of rotation D.

The driving system of the winding rod 11 is performed by a shaft 3 which meshes with the outside of the knitted fabric bundle 14 and sets the knitted fabric bundle 14 into a rotating state by friction. In this case, the shaft 3 meshes with the lower section of the knitted fabric bundle 14 so that its gravity increases friction. The end of the winding rod 11 which is still empty is inserted into the lower end of the upwardly inclined section 1.1 of the bearing groove 1. In the course of the winding process, as the diameter of the knitted fabric bundle 14 increases, the end of the winding rod translates upward in the upwardly inclined section 1.1 until it reaches the horizontal section 1.2, as shown in FIG. 2.

FIG. 3 shows that the cloth winding device 10 is switched to the winding tubular shape The knitted fabric 22 then serves as the cloth winding device 10'. The shorter winding rod 21 is installed for winding these cloth nets 22. Its end is set again in the bearing groove 2 in the side cheek 23. In this case, the side cheeks 23 are installed between the side cheeks 13 in such a manner that the winding rod 21 provided in the bearing groove 2 can also be driven by the shaft 3.

As shown in FIG. 4, the bearing groove 2 also has an upwardly inclined section 2.1 and a horizontal section 2.2. The upwardly inclined section 2.1 in this case has a flatter course than the upwardly inclined section 1.1 of the bearing groove for the winding rod 11. As a result, in the position shown in FIG. 4, after reaching the maximum possible diameter of the knitted fabric bundle 24, the winding rod 21 is located at a distance A greater than the distance A of the winding rod 11 from the rotation axis D of the cloth winding device 10 ′ The distance B. Furthermore, the guide roller 16 limits the maximum possible diameter of the knitted fabric bundle 24 after switching to winding the tubular knitted fabric web 22. However, since the winding rod 21 is at a greater distance from the position of the rotation axis D than the winding rod 11, when the tubular knitted fabric 22 is wound, it is larger than when the knitted knitted fabric 12 is wound. The diameter of the knitted fabric bundle. The shorter winding rod 21 can be arranged further away from the axis of rotation D without hitting the outer cover of the knitting machine.

The different sizes of the largest possible knitted fabric bundle diameter are shown in FIG. 5. FIG. 5 also shows that the position of the winding rod 21 is not only further outward, but also slightly deeper than the position of the winding rod 11 of the knitted fabric 12 for opening. The possible installation space can thus be used optimally.

6a and 6b respectively show the side cheeks 30 of the cloth winding device, other than that, which are not shown in detail, the knitted fabric net and tube for opening A common winding rod (not shown) of a knitted knitted fabric can be inserted therein. The first bearing block 31 with guide grooves 32 for the open knitted fabric can be attached to the side cheeks according to FIG. 6a to achieve the application of different knitted fabrics. When the tubular knitted fabric is to be wound, this bearing block 31 is replaced by another bearing block 33, as shown in FIG. 6b. The bearing block 33 has a bearing groove 34 that runs at a flatter angle than the bearing block 31. In addition, the bearing groove 34 extends further forward in the direction of the arrow 35, so that the winding rod for winding the tubular knitted fabric can be arranged more radially outward in the outer cover of the circular knitting machine. To this end, the side cheeks 30 are extended in the direction of arrow 35 by the attachment 36.
