Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a spinning machine in which a pneumatically loaded top roller holder arm is mounted on a bar-like holder of a machine by means of a support.

[0002]

2. Description of the Related Art In the case of spinning machines, for example, as known from DE-A-3732132, a central compressed air supply to the individual top roller holder arms is provided as a hose in the center of the machine, which runs in the machine direction. This is done via compressed air piping. Another hose branches off from the central pipe toward the top roller holder arm. However, all these hose lines are vulnerable and require additional installation space.

[0003]

SUMMARY OF THE INVENTION The object of the invention is to improve a spinning machine of the type mentioned at the outset in such a way that the central compressed air supply system is less susceptible and does not require additional installation space. .

[0004]

According to the present invention, there is provided according to the present invention, in a spinning machine of the type described at the outset, a plurality of polygonal tube members which are mounted on a machine and which guide compressed air through the machine. The problem is solved by attaching a closing element to the ends of these polygonal tube members, and fitting the connecting tube member into the end opening of the closing element of both polygonal tube members adjacent to each other.

[0005] In the case of a spinning frame formed according to the invention, the bar-shaped holder for the top roller holder arm is simultaneously used as a central compressed air guide system. Thus, a separate, fragile conventional hose for the compressed air supply system is not required here. The holding body is constituted by a plurality of individual polygonal tube members, and each of the polygonal tube members is connected to each other by a closing element and a connecting tube member so as to communicate with each other. And the compressed air supply system can be modularly assembled.

[0006] The closure element is fitted in an airtight manner, preferably with an adhesive, at the end of the polygonal tube member. The connecting pipe member is hermetically sealed, for example by an O-ring, and is fitted into the end opening of the closure element.

Advantageously, the polygonal tube member is mounted on the machine at a position corresponding to the location of the closure element in the axial direction, the closure element sealing the interior of the polygonal tube member against the point of attachment to the machine. It is. In this case, in particular, the mounting portion of the polygonal tube member is disposed at a portion where the compressed air of the closing element does not flow and guide, and between the closing element and the polygonal tube member, the tube inner side as viewed from the end side of the polygonal tube member. A packing seal is arranged at the bottom. Thus, for example, it is not necessary to seal the bolt connection hole between the polygonal tube member and the machine. The compressed air is guided completely bypassing the mounting point. Furthermore, the closing element serves to reinforce the polygonal tube member.

When connecting a plurality of polygonal tube members one after another,
A blind plug or a compressed air hose pipe is fitted into the end opening of the closing element attached to the end of the polygonal tube member located at the end. The blind plug is fitted, for example, at the end of the holder among the plurality of holders. When the compressed-air guide holders are arranged on both sides of the machine, these holders are connected by hoses which fit into the end openings of the closing element.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the compressed-air guide-type holder of a spinning machine according to the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 shows two polygonal tube members 10 and 11 of a bar-shaped holder of a spinning machine, which are formed here as square tube members. These polygonal tube members 1
0, 11 are provided with closing elements 12, 13 respectively at the ends of the polygonal tube members adjacent to each other. Closing elements 12, 13
Have circumferential grooves 14, 15 on the end faces of the polygonal tube members 10, 11 facing the inner chamber, in which the closing elements 12, 13 are provided with respect to the polygonal tube members 10, 11. The sealing adhesive is packed. The closing elements 12, 13 each have an opening 16 at its axially outer end face, which can be clearly seen from FIG. The opening 16 has O-rings 18, 1
A connecting pipe member 17 with a plug 9 is fitted and connects the two adjacent closing elements 12, 13 in communication. This connecting pipe member 17 is a polygonal pipe member 1.
It functions as a compressed air connection pipe that connects between 0 and 11. Thus, the plurality of tube members are connected in series by the closing element and the connecting tube member, but a blind plug or the opposite of the machine is provided in the opening 16 at the end of the polygon tube member located at the end. A hose for connecting to the end of the plurality of polygonal tube members connected at the side is moored. The closing elements 12, 13 furthermore have holes 20, 21 for fixing the polygonal tube members 10, 11 to a machine not shown here. These holes 20, 2
Reference numeral 1 is located at a location where compressed air is not guided. That is, the compressed air flows through the space formed near the holes 20 and 21 without communicating with the holes 20 and 21, and is guided through the connecting pipe member 17. As a result, the holes 20, 21 do not need to be sealed. Closing elements 12, 13
Are located closer to the inner chamber of the tube than the attachment points 20 and 21 when viewed from the ends of the polygonal tube members 10 and 11.

FIG. 3 shows the closing elements 12, 1 of FIG.
3 does not have the peripheral grooves 14 and 15 for the adhesive,
Instead, closure elements 12 ', 13' are shown here, which have frusto-conical inner ends 22, 23 against which a sealing ring, not shown, is pressed. Other constructions of the closure elements 12 ', 13' are similar to the closure elements 12, 13 described above.
Is consistent with the structure.
