Abstract

The aim of the invention is to facilitate and simplify the installation of spindle supports (8, 12, 13) on the spindle supporting bridges (5) of a ring spinning frame. For this purpose, the spindle supporting bridges have bifurcated ends and the seats (14) for the spindle supports arranged on the bifurcated ends (17) engage with the spindle supports in windows which remain free for all spindle gauges (11', 11'') provided for a ring spinning frame.

Description

Spindle support bridges for ring spinning machines

technical field

The invention relates to a spindle support bridge for a ring spinning machine, on both sides of which at least one spindle support, extending from central support to central support, accommodating a spindle bearing housing, extends in each case.

Background technique

The spindle holder can have any desired shape. However, they are preferably cylindrical, in particular configured as a tube, which is a torsion-proof and inexpensive semi-finished product. However, the individual tube as a spindle carrier requires any kind of machining in order to ensure that not only itself but also the spindle bearing housing arranged on it fits in the correct position and also remains in this position, ie does not rotate about the tube axis. This machining is avoided by additionally preferably providing the two spindle supports, in particular arranged vertically one above the other. The two spindle supports can be designed cylindrically and they and the spindle bearing housings arranged thereon can be fixed by clamping at any spindle gauge.

Such a spindle support is disclosed in DD 29 797. But this publication does not specify how the spindle support should be fixed on the frame of the ring spinning machine.

The individual parts of the spindle carrier each extend in a section, ie from the center support to the center support, on which they are respectively fastened by means of the spindle support bridges. The spindle holders should be fastened without overlapping their abutment points, since simultaneous assembly of up to four spindle holders at a time is not possible without auxiliary devices. The clamping devices for the spindle supports are separated at the docking points, which is greatly impaired by the small space provided between the two spindle bearing housings, especially in the case of small spindle gauges.

Contents of the invention

It is therefore the object of the invention to allow such a spindle carrier to be fastened securely, in sections and in pairs. The invention solves this object in that the invention allows the spindle carrier bridges to be separated in a fork-shaped manner, and the receptacle for the spindle carrier can act between the spindle bearing housing adjacent to the docking point and the corresponding immediately following spindle bearing housing on the spindle holder. In this way, successive spindle supports or pairs of spindle supports along the ring spinning machine can each be assembled on their own and optionally also disassembled.

The advantages of the invention are already present if the spindle carrier has any desired shape, for example angular or T-shaped. However, the advantages of the invention are convincing if the spindle supports are cylindrical and in particular every two spindle supports are preferably arranged one above the other. Such a spindle carrier does not require machining for the purpose of securing itself and the spindle bearing housing arranged thereon. This fastening can preferably take place by clamping.

If the one-piece spindle support bridge is to be available for all spindle gauges set on the ring spinning machine, this results in additional tasks, namely the mounting points for the spindle supports and the window spacing With an open setting, the window is not covered by the spindle bearing housing at all set spindle gauges. This object is also solved by the features of the independent claims.

Description of drawings

Exemplary embodiments of the invention are shown in the drawings. in:

Fig. 1 is a schematic cross-sectional view of a ring spinning machine;

Figure 2 is a top view of the clamping area of a spindle support bridge with a large first gauge;

FIG. 3 is a plan view of the clamping region of a spindle support bridge with a second small gauge.

Detailed ways

As can be seen from FIG. 1 , the central support 1 of the ring spinning machine has a foot 2 from which two support tubes 3 extend upwards and support an upper part 4 . This upper part supports the not shown drafting mechanism and the creels of the ring spinning machine. The other working elements of the ring spinning machine, such as the ring bar, the thread guide, the spindle drives and their actuating elements, are not shown for the sake of clarity. This intermediate support is for example disclosed by DE 899 608.

The spindle support bridge 5 is fastened, preferably clamped, to the support tube 3 . According to FIG. 2, this clamping fastening can be carried out by means of a countersunk screw 6 which can be screwed against the support tube. Clamping can also be carried out according to FIG. 3 in that the spindle carrier bridge 5 is separated in a vertical plane and can rest against the carrier tube from both sides. They are then fastened to the support tube 3 by means of connecting elements such as screws 7 . The advantage of this alternative is that the spindle carrier bridge can be retrofitted and easily replaced.

Arranged on the spindle support bridge 5 is a spindle support 8 which serves as a support for the spindle bearing housing 9 . The spindle is supported in the spindle bearing housing, of which only the tube 10 slipped onto the spindle is described here. The spindle bearing housing 9 is clamped and fixed on the spindle support 8 with corresponding spindle gauges 11 ′, 11 ″.

In a preferred embodiment, the spindle support 8 comprises two vertically superimposed tubes 12, 13 which extend from the intermediate support 1 to the intermediate support, a pair of which are shown in FIGS. 2 and 3 contact. The tubes 12 , 13 are secured to the spindle carrier bridge 5 via the receiving points 14 . The receptacle 14 forming the clamping connection comprises a semi-cylindrical bearing shell 15 on the spindle support bridge and a clamping element 16 which can be screwed onto the spindle support bridge so that the tubes 12 , 13 can be pressed against the bearing shell.

The receptacle 14 is not arranged above the abutment points of the spindle carrier 8 between two spindle bearing housings adjacent to these abutment points. Rather, according to the invention, the spindle carrier bridge 5 is formed in the form of a fork at the end. The fork arms 17 each have one of the receptacles 14 which engages on the tubes between the spindle bearing housing 9 ′ adjacent to the abutment point of the tubes 12 , 13 and the respective immediately adjacent spindle bearing housing 9 ″. .

The relative distance of the two receptacles 14 on the fork arm 17 is selected in such a way that said receptacles act on windows which are located at all set spindle gauges 11 ′, 11 ″ of the spindle bearing housing 9 . The advantage of this measure is that the same spindle support bridge 5 can be installed for all set spindle gauges.

FIG. 2 thus shows an example of a maximum set spindle gauge 11 ′, in which the receptacle 14 engages closely next to the spindle bearing housing 9 ′ adjacent to the abutment point of the tubes 12 , 13 . In contrast, FIG. 3 shows an example of a minimum set spindle gauge 11 ″, in which the receptacle engages closely next to the next spindle bearing housing 9 ″. It goes without saying that the receptacle 14 must not be wider than the window.
