Description

CO94 U 000003 DESCRIPTION of the Utility Model entitled: "IMPROVED POSITIVE POWER SUPPLY, HAVING THE WIRE INPUT POSITIONED LATERALLY AND APPLICABLE TO KNITWEAR MACHINES AND TO TEXTILE MACHINERY IN GENERAL" of the Lord Angelo PAGGIARO, of Italian nationality, resident in Via Pradisera n°56 Gallarate - (Varese) - DESCRIPTION The present invention relates to an improved positive feeder having the thread entry positioned laterally, to facilitate the replacement of the belt used for its operation, and applicable to machines used for the production of fabrics, sweaters and clothing items, and to textile machinery in general. As is known, circular knitting machines feature several yarn feeders, which are generally mounted on two rings, and currently have the yarn inlet positioned in their respective front parts. The one-piece toothed belt, used for their operation, is positioned immediately behind the wire entry in contact with the toothed wheel of each individual feeder. In case of a normal castle or creel, the thread that starts from the fortress, after having passed on of the supports provided in the machine, enters the feeder through a bushing positioned on a rod mounted in front of it. In the case of a tube creel; the -Thread starting from the bobbin enters the tubes of the creel and thus arrives directly at the feeder; the end part of the tube is -Fixed to the rod mounted in front of it. When it happens to replace the toothed belt, in the case of a normal castle or creel, since the -Thread entry is positioned in front of the toothed wheel, all the Threads must be cut to be able to reposition the new belt, threading it from under the machine. Once the new one is in place, the threads need to be tied, and this takes a lot of time. If you then need to replace a belt with a tube creel, the problems double, since in addition to cutting the wires you also have to detach all the terminal tubes connected to the feeder input shaft. Once the new belt has been positioned, threading it from under the machine, you need to replace the terminal tubes, use the compressed air gun to thread all the wires and re-tie them. In this case, the time will vary depending on how many feeders are installed, corresponding to the number of feeds, but as you can imagine, it takes a lot of time, combined with a lot of patience. Currently this type of creel is increasingly in use, and is replacing both the castle and the normal creel, given the numerous advantages it offers: the threading from the cone to the feeder is done quickly with a compressed air gun; when working with natural fibres, since the longer path It is inside the tube, there is less dust in the air and pollution between the various fibres being processed is also reduced. The aim of the present invention is to solve the problems and drawbacks mentioned above by creating an improved feeder having the wire inlet positioned laterally, so that the belt does not interfere with the wire inlet, and thus making it possible to replace it quickly and easily. With this power supply, therefore, the operator's work, in case of belt replacement, is considerably facilitated, thus creating optimal conditions for increasing productivity. Furthermore, the power supply in question, due to its peculiar manufacturing characteristics, does not involve higher costs, given that it uses the same parts, but assembled in a more rational and functional way. Further features and advantages of the present invention will be better highlighted through an examination of the description of the preferred, but not exclusive, embodiment of the improved power supply in question, with the aid of the attached drawings, in which: Figure 1 is a perspective view of the inventor's improved invention having the wire entry positioned laterally; Figure 2 represents a front view of the same improved power supply illustrated in Figure 1; Figure 3 represents a side view of two improved power supplies in question, mounted on two rings, in position Work With particular reference to the numerical symbols of the aforementioned -Figures. and in particular to -Figure 1 and 2, the improved power supply in question in the present invention is indicated in its entirety with the reference letter <A) . In this feeder, the rod 1 supporting the end part of the tube 2, in which the -Thread 3 comes out, coming from a reel of -Thread (not shown), passes through a -Brake 4. The important peculiarity of the invention is constituted by the fact, as more visible in Figure 2, that the above-mentioned details are mounted laterally, in such a way that the toothed belt 8 does not interfere with the terminal part of the tube 2 anchored to the laterally mounted rod 1, and indeed is outside of the same. Subsequently, the wire 3 supports a first lever 5 designed to stop the machine in the event of its breakage and is wrapped in several turns around a drum 6. The rotation of said drum 6 is controlled by a pulley 7 coaxially integral with it, and is moved by a toothed belt 8, formed in a single piece. Before being sent to the textile machine M, the Thread 3 rests on the second lever 9, like the first, which is designed to intervene in the event of its breakage, and on a support with a bushing 10. In this case the rod 1 supporting the end part of the tube and the brake group is mounted in a 90° position with respect to the body of the power supply. It is also possible to mount it with a different inclination, for example 45' or 30°, the important thing is the maintaining the input group Wire behind the toothed belt. In -Figure 3 is represented the side view opposite to the -Thread entrance of two feeders (A), positioned as follows; the first on a low (small) ring 11, the second on the high (large) ring 12, as actually happens on a circular knitting machine. In particular, we would like to emphasize with these drawings that, by mounting the toothed belts from below, there are no obstacles, everything happens without detaching the end tubes and without cutting the wires. The invention thus conceived is susceptible to numerous modifications and variations, all of which fall within the scope of the inventive concept.

Claims

CLAIMS 1. Improved positive feeder applicable to knitting machines and textile machinery in general, having the thread entry positioned laterally, or in any case in such a way that the belt, suitable for their operation, is outside the thread entry into the feeder, to facilitate the replacement of the aforementioned belt.

2. Improved feeder, as in claim 1, characterised by -The fact that the rod -Provided with a bushing for the entry of the -Wire into the feeder is positioned laterally, and is located between the belt and the attachment of the feeder itself to the machine, and can vary according to an inclination, with respect to the body of the feeder, from 0 to 180 degrees.

3. Improved feeder, as in one or more preceding claims, characterised by -the fact that the support rod of the terminal part of the tube coming from the creel, in which the thread comes out, is positioned laterally, and is located between the belt and the attachment of the 1 ' to the inventor himself to the machine, and can vary according to an inclination, with respect to the body of the feeder, from 0 to 180 degrees.

4. Improved feeder, as per one or more preceding claims, characterised by -the fact that the thread brake group is mounted laterally, and is located between the belt and the attachment of the feeder itself to the machine, and can vary according to an inclination, with respect to the body of the feeder, from 0 to 180 degrees.

5. Improved power supply, as claimed in one or more claims previous, characterized by the fact that at least the entrance of the Wire is positioned between the belt and the power supply attachment same as the machine, and can vary according to an inclination, relative to the power supply body, from 0 to 180 degrees.
