(54) TRAVELLING SERVICE CARRIAGE FOR TWISTING FRAMES (71) We, SAURER-ALLMA GmbH I ALL- GAUER MASCHINENBAU, of Leonhardstrasse 19, 8960 Kempten, Germany, a Body Corporate organised under the laws of Germany, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement: The invention relates to an installation comprising a plurality of thread twisting frames and a travelling service carriage for the frames.
Service carriages travel along the sides of thread twisting frames and fulfil various functions. Thus, in the case of double twisting frames, in the event of stoppage they effect the feeding and insertion of thread and also the tying of broken threads. The relatively complicated service carriages must be capable of being located very accurately in the longitudinal direction of the frame, but must be able to position themselves in accordance with the level of the twisting spindles to be serviced.
Service carriages are relatively very expensive, hence as far as possible one carriage has to be associated with a plurality of twisting frames.
A running rail arrangement for a ring twisting frame is known (see German
Offenlegungsschrift 2,143,205) in which a lower running rail is secured in the lower region of the frame, approximately at the level of the spindles bank. An upper running rail is arranged above the creel and above head height. In order that the service carriage may travel from one side of the frame to the other, a U-shaped transfer rail is provided which extends from one side of the frame to the other and is arranged as an extension of the upper running rail. Likewise, there is also provided in the region of the lower running rail a U-shaDed transfer rail which proiects beyond the end of the frame by about half the width of the frame.This projecting rail uses up some of the space between aligned twisting frames, and for a required minimum width of passageway between the frames the frames must be arranged at a greater distance from one another.
This applies similarly when the lower running rail is arranged on the frame near the floor, as is known from another running rail arrangement (see German Patent
Specification No. 1,685,932).
According to the invention there is provided an installation comprising a plurality of thread twisting frames and a travelling service carriage for the frames, each side of each frame having a lower running rail for supporting the service carriage and an upper running rail for guiding the carriage, wherein the installation further comprises a transfer rail and a parallel auxiliary rail for transfer of the service carriage from one side of a frame to the other side of the frame and a transfer rail and a parallel auxiliary rail for transfer of the service carriage from one frame to another frame, each transfer rail and each auxiliary rail being above the height of the frames.
With this arrangement of running rails, the service carriage will be guided during movement along the longitudinal sides of a frame, by an upper running rail and a lower running rail. However, the lower running rail ends at the end of the frame. The support of the service carriage during travel around the end of the frame is on an auxiliary rail and a transfer rail. Since both the auxiliary and the transfer rails are preferably arranged above head height, they do not use up space between the machines which is required for a passageway. Consequently, adjacent frames, may be situated closer together than was hitherto possible.
The invention will now be described by way of example and with reference to the drawings, in which: Fig. 1 is a plan view of a plurality of twisting frames with a running rail arrangement for a service carriage,
Fig. 2 is a vertical section on the lines
II-II of Fig. 1, also showing the service carriage, and
Fig. 3 is a vertical section on the line
III-III of Fig. 1, also showing the service carriage.
In Fig. 1 of the drawings there are indicated four adjacent thread twisting frames 1, 2, 3 and 4. Upper running rails 5 and lower running rails 6 are arranged on each side of each frame for the running wheels of a service carriage 7 that can travel along the sides of each frame. The service carriage, which moves automatically along the frames 1 to 4, serves to overcome trouble in the event of thread breakage, and also serves for threading the thread into the twisting bobbin or for applying the thread to the take-up bobbin.
In order that the service carriage 7 may be capable of travelling from one side of a frame to another there is provided at one end of each frame, a transfer rail 8 and a parallel auxiliary rail 10. Similar transfer and auxiliary rails 8' and 10' are provided to enable the service carriage to travel from one frame to the adjacent frame, and transfer and auxiliary rails 8" and 10" enable travel of the carriage directly between frame 4 and frame 1. The transfer rails 8, 8' and 8" and the auxiliary rails 10, 10' and 10" are arranged above the twisting frames 1, 2, 3 and 4 to ensure that they are above head height K. Preferably the transfer rails 8, 8' and 8" are continuations of the upper running rails 5.
As can be seen from Figs. 2 and 3, during normal travel of the service carriage 7 longitudinally along one side of the twisting frame 1 the lower rails 6 are the bearing rails that take the weight of the heavy service carriage 7, which in practice may weigh about 400 kg. The upper running rails 5 are, during travel along the frame, supporting rails against which the service carriage is supported against movement laterally of its direction of travel F. Supporting is effected by means of at least one roller 12 rotatable about a vertical axis in the upper region of the service carriage 7, the roller 12 taking up essentially only the forces re; sulting from the lateral tilting moment. The service carriage 7 is moved by means of a lower wheel 14 supported on the lower running rail 6 and driven by a brake motor 13.
After reaching the spindle to be serviced, the carriage is braked, and positioned with great accuracy in front of the spindle. The long distance of the upper running rail 5 from the lower running rail 6 which is located near the floor, makes possible very accurate guiding of the service carriage along the twisting frame 1, 2, 3 or 4, it is also advantageous that the heavy weight of the service carriage is applied- to the running rail 6 arranged wholly beneath the twisting frame near the floor. Since the wheel 14 which is heavily loaded in the vertical direction is driven, positioning of the service carriage 7 to great accuracy is possible, since slip between the lower running rail 6 and the wheel 14 is avoided.
In the embodiment illustrated the transfer rails 8, 8', and 8" have upper running surfaces 15 for an auxiliary driving wheel 16 of the service carriage 7 and a further wheel which is not shown in the drawings.
During travel of the service carriage from one frame to another or from one side of a frame to the other side the weight of the carriage is shared substantially equally between the auxiliary driving wheel 16 the further wheel running on the transfer rails 8, 8' and 8", and an auxiliary supporting wheel 11 running on the auxiliary rails 10, 10' and 10". The auxiliary driving wheel 16 and the further wheel running on the transfer rails 8, 8 and 8" act as guide wheels. The auxiliary driving wheel 16, which is connected to an auxiliary driving motor 17, the further wheel running on the transfer rail 8, 8' and 8" and the auxiliary supporting wheel 11 are arranged on the service carriage and are rotatable about horizontal axes.
As can be seen from Fig. 1 of the drawings, the service carriage 7 can travel from one side of the frame to the other side by means of the transfer rails 8 and the auxiliary rails 10, the transfer rail 8 being located inwardly. Travel of the service carriage 7 from one frame to an adjacent frame is enabled by the transfer rails 8' and the auxiliary rails 10', the rails 8' being outward and the rail 10' being parallel thereto above the twisting frame, and having a smaller radius of curvature. In Fig. 1 it can be seen that the lower running rails 6 and the auxiliary rails 10, 10' and 10" overlap somewhat in the longitudinal direction of each twisting frame, so that a smooth transfer of the service carriage 7 either to the other side of the frame or to another frame is ensured.
In the embodiment illustrated in Fig. 1 of the drawings a plurality of twisting frames are arranged in series adjacent one another.
In order that the service carriage 7 may always pass along the frames in the same direction there is provided from the last frame 4 to the first frame 1 a transfer rail 8" extending across the ends of the frames and having a corresponding parallel auxiliary rail 10". In the case of twisting frames arranged one behind the other in one direction the transfer rails and the auxiliary rails arranged above head height would be straight. However, -- other paths of travel between the frames may be provided, with out the rails obstructing the spaces between the frames.
The upper running rails 5 and the lower running rails 6 of the rail arrangement are secured to the respective individual frames 1 to 4. For exact relative positioning, the transfer rails and auxiliary rails 8, 8' and 8" and 10, 10' and 10" respectively are preferably also arranged on the respective twisting frames 1 to 4. As can be seen from Figs. 2 and 3 of the drawings, this can be effected by securing the transfer rails and auxiliary rails 8, 8' and 8" and 10, 10' and 10" respectively to a supporting frame 19 mounted on the twisting frames.
Departing from the embodiment shown in the drawings it is also possible to arrange the auxiliary rail displaced in height with respect to the transfer rail 8, below or above the transfer rails, as long as both rails are above head height. Referring to Fig. 3, the transfer and auxiliary rails project beyond the ends of the frames but, because they are above head height, the space beneath the rails may be utilised as a passageway, the passageway being occasionally obstructed by the service carriage.
