Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spindle frame for a multi-spindle double twisting machine.

Multi-spindle double twisting machines are already well known and are already on the market. There are two basic types of double twisting machines: one is a vertical type that is used with the axis of the spindle unit vertical, and the other is a horizontal type that is used with the axis of the spindle unit horizontal. It is something. A horizontal version is disclosed, for example, in US Pat. No. 3,641,757.

Vertical spindle machines generally have two parallel rows of spindle units on the same plane, and horizontal spindle machines generally have two rows of spindle units on either side of the spindle machine. This horizontal spindle machine has the great advantage of being extremely economical, since it is possible to arrange significantly more spindles than a vertical machine for the same floor space. Furthermore, horizontal spindle machines have significantly lower noise factors. Thus, horizontal spindle machines are more effective and functional than vertical machines, but vertical machines are simpler in construction, less expensive, and require less space. , and has the advantage of being easy to operate. For the above reasons, both horizontal spindle machines and vertical spindles are commonly used.

Manufacturers interested in supplying machines for the horizontal and vertical spindle market must now produce horizontal and vertical spindle machines and parts thereof that are suitable for high productivity. In view of this, the primary concern in the manufacture of double twisting machines lies in the construction of the spindle frame on which the spindle unit is mounted and which supports it together with the package during the twisting operation. In the past, it has been necessary to fabricate and stock various parts for spindle frames of vertical and horizontal spindle machines.
However, according to the present invention, since the spindle frame is formed as a universal spindle frame that can be used commonly for both horizontal and vertical machines, it is only necessary to manufacture and stock one type of support plate. Therefore, there is no need to carry out production in accordance with special orders, and the product becomes cheaper.

Another important part of the double twisting machine is the partition wall placed between the rows of spindle units. This partition wall can be used if the thread of one row of spindles breaks.
This is a part that prevents this thread from becoming entangled with the spindle units of the adjacent row. Conventionally, different partition walls are generally required for each type of machine, and in practice are generally not used in horizontal spindle machines. This partition therefore poses another problem for manufacturers of horizontal and vertical spindle machines. However, according to the present invention, the partition wall has a structure that can be used in both horizontal and vertical machines, and can be incorporated as an integral part of the spindle frame structure when used in either model. can.
Furthermore, this partition wall is designed to be movably adjustable in combination with the support of the ballooning thread guide, thereby providing effective access to the spindle unit during package changes and spindle maintenance.

In both horizontal spindle machines and vertical spindle machines, a belt (tape) that frictionally engages each warb of the spindle unit to rotate it.
A drive system is used to drive the A spindle frame is therefore formed in such a way that this belt drive system can be at least partially mounted.
Conventionally, a different spindle frame design is required for each different model. On the other hand, according to the present invention, the spindle frame structure is independent from the belt drive system, and the belt drive system can be used with a general spindle unit structure for spindle machines having different types of belt drive systems. ,
Attached to spindle machine.

Another difference between a typical horizontal spindle machine and a vertical spindle machine is the difference in the means for preventing rotation of the package during operation. In a standard vertical spindle machine, a magnet is attached to a disk in the spindle unit, which attracts another magnet attached to the machine frame; in a standard horizontal spindle machine, A weight is mounted eccentrically from the axis of the spindle unit to prevent rotation of the spindle about its horizontal axis. Different spindle unit parts are required to accommodate these different anti-rotation means. According to the invention, on the other hand, a spindle unit part is provided which can be adapted both to the magnet and to the weight, so that this spindle unit part can be used both for horizontal spindle machines and for vertical spindle machines; Therefore, it offers the same manufacturing and stock advantages as a spindle frame.

The gist of the invention is a spindle frame for a double twisting machine, in which a vertical row of spindles is supported on each side of a longitudinal midplane perpendicular to the spindle frame;
In a version in which the longitudinal midplane forms the vertical longitudinal midplane of the double twisting machine when the spindle is arranged vertically, the spindle frame consists of two support plates, which The spindles are connected to each other at the edges and each support a row of spindles, and the spindles are supported on the support plate such that the warb is located on one side of the support plate and the spindle is located on the other side of the support plate. , whereby the support plate is selectively located in a horizontal or vertical plane, with its longitudinal ends
This is due to the fact that it is fixed to a vertical machine frame that limits each machine section.

The advantage of the invention, as already mentioned, is that the spindle frame is designed as a universal spindle frame that can be used in common for both horizontal and vertical machines, so that only one type of support plate can be produced. Therefore, there is no need to carry out production in response to special orders, and the product is inexpensive.

Next, the present invention will be specifically explained with reference to the illustrated embodiments.

1 and 2 show a section of a two-part two-for-one double twisting machine. Each section is located between two sharp machine frames 1. The spindle frame 2 according to the present invention arranged in each section is the same for the vertical machine and the horizontal machine, and the one in Fig. 1 is arranged horizontally, and the one in Fig. 2 is arranged with the width direction vertical. ing.

In the embodiment shown in FIG. 1, the spindle frames 2 of each section are attached between the machine frames 1 via fixing angle members 31. This spindle frame 2 is provided with side flanges 3 on both sides. As shown in detail in FIG. 3, this spindle frame 2 consists of two support plates 2.1 and 2.1 with a U-shaped cross section.
2, each supporting plate 2.1, 2.2
are connected to each other by their flanges 25. A partition wall is attached to the center of the central plane of the spindle frame 2. This partition wall consists of a lower part 4 with a U-shaped cross-section and an upper part 5 inserted into this lower part 4 in a telescopically height-adjustable manner. A support 14 for a balloon thread guide 13 is mounted on the upper part 5 of the partition wall. The lower part 4 is formed from two stepped bent plates which are joined together in one section and clamped between the two flanges 25 and are thereby connected to the spindle frame.

As can also be seen in FIG. 3, the upper part 5 and the lower part 4 of the partition wall are connected by a threaded spindle 27 and a spindle nut 28. One such threaded spindle 27 is provided for each section at each end of the partition wall. By turning this threaded spindle 27, the height of the balloon thread guide 13 is adjusted together with the height of the partition wall.

A bearing casing (spindle unit mounting) 8 for the spindle 6 is arranged stationary on the spindle frame 2. The spindle 6 includes a worm 7, a ballooning limiting member 9, a protection tube 10,
It consists of a package 11 and an upper part 12 of the spindle. The structure of the two-or-one spindle itself is already known. A two-or-one spindle of this type is described, for example, in US Pat. No. 3,295,306. The type of connection between the bearing housing 8 and the spindle frame 2 is known, for example from US Pat. No. 3,716,980. An opening 20 in the spindle frame for mounting the bearing casing 8 is of the bayonet type. The spindle frame 2 is connected to the machine frame 1 in each section by means of fixing angle members 31. An overfeed roller 15 is provided downstream of the ballooning yarn guide 13.
A rotationally driven shaft is arranged. A traverse rod 16 with a traverse thread guide 17 is connected to the overfeed roller 15. The traverse rod 16 extends in the longitudinal direction of the machine. A drive roller 18 is attached to a further rotationally driven shaft, by means of which drive roller 18 the tube thread 19 is frictionally driven.
Since this attachment method of the pipe thread 19 is common, explanation thereof will be omitted.

The worm 7 is cantilevered to 1 of the spindle frame 2.
The arrangement of the spindle is made effective by the fact that the spindle itself is arranged on the other side of the spindle frame 2. The worm 7 is driven by a drive belt 22 extending tangentially to the worm.
(tape). A guide and tension roller 33 presses the drive belt to press it against the warb 7 and guide it. A beam 26 is provided for guiding and supporting the tensioning roller 33. This beam 26 is again arranged between two machine frames 1. As already mentioned, this machine slot 1 is 1
Separates the machinery categories. This beam 26 is separated from the spindle frame 2 and fixed to the machine frame by a fixing angle member 32. The spindle frame 2 and the spindle bearing as well as the belt guide are therefore isolated from each other as far as vibrations and noise are concerned.

In contrast to vertical machines, horizontal machines have two rows of horizontally positioned spindles arranged on each side of the machine (see Figure 2). Only one shaft for overfeed rollers 15 is provided on each machine side, but twice as many overfeed rollers 1 are provided.
5 is attached to this one shaft. On both sides of the machine, two sets of drive systems are arranged, which correspond to the drive systems of the vertical machine shown in FIG. For example, the spindles on each side of the machine are driven by drive belts 23 and 24, respectively. spindle frame 2
Together with the covers 29, 30 they form a box-shaped casing in which the cantilevered warp 17 and the drive belts 23, 24 are guided. Inside this box-shaped casing, there is also a beam 26 for installing guide and tension rollers 33 for the drive belts 23 and 24, similar to the vertical machine.
is located. Even with this horizontal machine, this beam 2
6 is insulated from the spindle frame 2 as far as vibration and noise are concerned, and is fixed to the machine frame 1 of each machine section via a fixing angle member 32 as shown in FIG.

FIG. 4 is a schematic plan view of a two-or-one double twisting machine that can be used both horizontally and vertically.
Each machine is of two-part type and has a side indicated by arrow A and a side indicated by arrow B;
and is divided into machine sections by a machine frame 1 in the longitudinal direction. The structure of each machine segment is all the same. At one end of the machine there is a drive casing with an electric motor 34 and a transmission (not shown) for driving the drive belt for the spindle, the drive roller of the take-up bobbin, the shaft of the overfeed roller and the traverse movement device. It is being At the other end of the machine, primarily the tensioning roller and deflection roller of the drive belt are arranged in the casing 83.

A horizontal machine of the type shown in FIGS. 3 and 5 has already been proposed, for example, in US Pat. No. 3,641,757 (Bag. 674). The construction of this machine is advantageous with regard to environmental impact (noise damping, vibration damping) and operation. The horizontal machine can also be equipped with a casing, as disclosed in the above-mentioned US patent. The advantage of the spindle frame of the invention shown in FIG. 5 is that the spindles of one row are offset with respect to the spindles of the other row. This has the advantage that the thread passage is unobstructed. The same spindle frame can also be used in small vertical machines at low cost. Therefore, as shown in FIG. 1, the spindle 6 on the left side of the drawing and the spindle on the right side of the drawing (A side, B side) are arranged offset from each other.
The same applies to the one shown in FIG. This results in a free space (see FIG. 5), i.e. a free space 80 corresponding to or slightly larger than half the space of the spindle, at each machine end in each machine section. Storage containers 21 and the like can be installed within this free space 80.

However, the layout of the spindle frame of the present invention is such that the plates 2.1, 2.
The plates 2.1, 2.2 can be formed in such a way that two free spaces 80 are provided on opposite sides of the machine section so that the spindles can be arranged offset from each other. It can also be provided that the free spaces 80 of each plate 2.1, 2.2 occur at the same end of the machine section 81. In that case, both spindle rows of the spindle frame are arranged opposite each other as shown in FIG. 6 for one machine section. This spindle frame, shown in FIG. 6, can be used in both vertical and horizontal machines.

The spindle will now be described with reference to FIGS. 7 and 8.

The two-or-one double-twist spindle shown in FIG. 7 has the construction specified in DIN 63955. This spindle mainly consists of a rotating rotor 101 and a package carrier 10 supported on this rotor.
It consists of 2. Rotor 101 is supported within casing 103 via ball bearings. This rotor 101 includes a warb 104 and a drive belt 105.
driven by. A disk 106 and a thread sliding surface 107 (ballooning thread guide) are fixed to the rotor. The package carrier 102 is mounted on the spindle shank via ball bearings 118, 119. The package carrier 102 primarily consists of a spool pot 109, a spool uptake 110, and a package carrier plate 111. Connect the thread brake 112 (indicated by a dashed line in FIG. 7) to the spool uptake 11.
It can also be inserted within 0.

Package carrier plate 111 includes segments 113 and mounting members 114. Details of these segments 113 and attachment members 114 are shown in FIG. Segment 113 is suitable for mounting magnet 115. When this spindle unit is used in a two-or-one twister with its axis vertical, this magnet 115 interacts with a stationary magnet 116. This acting force acts as a resistance to the rotational force of the package carrier 102, which includes the spool pot 109, the spool uptake 110, and the package carrier plate 111.

When this spindle unit is used in a two-or-one twister with its axis horizontal, a weight 117 is attached to the attachment member 114. For this purpose, the weight 117 has a hole into which the elastic expansion plug of the attachment member 114 is inserted and the weight 117 is locked by means of a radial projection of the expansion plug. In such a case, where the spindle unit is arranged with its axis horizontal, this weight prevents rotation of the package carrier.

The manner in which magnets 115, 116 and weight 117 are secured is not critical to the invention. The important point is to form the package carrier plate 111 in such a way that either the magnet or the weight is fixed. Magnets or weights may be glued to the package carrier.
