Universal transport mechanism for auxiliary devices in weaving mills

Abstract: Universal transport mechanism for auxiliary devices in weaving mills, with the characteristic that it consists of one single rail (3) mounted above the weaving machines, with two or more guides (4) along which respective auxiliary devices (5, 6, 7, 10, 11) can travel unhindered by each other along several weaving machines.

Description: This invention concerns an arrangement of several weaving machines comprising an universal transport mechanism with auxiliary devices. By auxiliary devices is meant for example a cleaning device, or devices for automatic thread repair, etc. It is common technology for cleaning devices for weaving machines to travel along a rail extending above the weaving machines. It is also common for thread repair devices to travel along rails. It is clear that with further automation of weaving mills, it will be necessary to be able to present more and more auxiliary devices to parts of the weaving machine, in order to carry out automatic repairs, deliver yarn packages and suchlike. As a result, it may be necessary to install several rail systems above and alongside the weaving machines in order to enable all the devices to be properly presented to the weaving machine. However, such an arrangement would have the disadvantage that access to the weaving machine would be severly restricted. The present invention concerns an arrangement which does not have this disadvantage. For this purpose it is characterized in that said transport mechanism consists of one single rail mounted above the weaving machines, with two or more guides along which said respective auxiliary devices can travel unhindered past each other along said weaving machines. In order to explain the characteristics of the invention, the following preferred embodiments are described, by way of example only and without being limitative in any way, with reference to the accompanying drawings, where: Figure 1 is a perspective view of the transport mechanism according to the invention; Figure 2 shows a practical embodiment as a cross-section through the rail; Figures 3 and 4 show two variants of the embodiment shown in Figure 2. As shown in Figure 1, the transport mechanism 1 according to the invention consists essentially of one single rail 3 mounted above the weaving machines 2, with several guides 4A, 4B and 4C along which several auxiliary devices 5, 6 and 7 respectively can travel unhindered relative to each other. In the most preferred embodiment, the rail 3 is supported by stanchions 8 fixed to the ground between the weaving machines 3. In a variant, the rail could also be suspended from the roof of the weaving mill or suchlike. As shown in Figure 1, the rail is preferably designed so that the most central guide 4B carries the cleaning device 5 which with its wide arms 9 can easily move over the other auxiliary devices. Figure 2 shows a variant in which the rail 3 consists of an I section whose flanges form the guides 4A to 4C. Figure 3 shows yet another variant in which the various guides 4A to 4C of the rail 3 are arranged side by side. Finally, Figure 4 shows a variant for five auxiliary devices 5, 6, 7, 10 and 11 which operate with guides 4A, 4B, 4C, 4D and 4E respectively, where the auxiliary devices consists of, for example, respectively an automatic weft thread repair device, a cleaning device, a device for repairing warp thread breaks, a separate cleaning system for the reed and a package delivery system. Said guides 4A to 4E are positioned so that each auxiliary device finds itself above the part of the weaving machine on which it must operate.

Claims: Arrangement of several weaving machines comprising a Universal transport mechanism with auxiliary devices, characterized in that said transport mechanism consists of one single rail (3) mounted above the weaving machines, with two or more guides (4) along which said respective auxiliary devices (5,6,7,10,11) can travel unhindered past each other along said weaving machines. Universal transport mechanism for auxiliary devices in weaving mills as in claim 1, with the characteristic that each guide (4) is located so that each auxiliary device finds itself above the part of the weaving machine on which it must operate. Universal transport mechanism for auxiliary devices in weaving mills as in claim 1 or 2, with the characteristic that the most central guide (4B) is used for transport of the general cleaning device (5) for the weaving machines. Universal transport mechanism for auxiliary devices in weaving mills according to any of the above claims, with the characteristic that the rail (3) is centrally supported.
