Description of the invention: [Technical field of inventions] Field of the Invention The present invention relates to the delivery of a yarn in a textile machine according to the first sentence of the first sentence of the first application of the patent application. mechanism. BACKGROUND OF THE INVENTION In the production or processing of yarns and further processing of yarns, a conveyor mechanism as previously described is used to guide one or more yarns 10 in a textile machine, this type of conveying mechanism having At least one driven transport roller, one or more yarns being guided around the drum. The multiple partial circuit of the yarn surrounding the transport roller is in this case completed by a guide roller assigned to the transport roller so that the yarn is guided by multiple loops around the two rollers. A transport mechanism of this type is known, for example, from DE 1 926 308. The known transport mechanism has a driven transport roller and a guide roller that is rotatably fixed to the transport roller. For guiding, the yarn is guided by multiple partial loops on the drum housing. During the yarn travel, for example due to faults such as yarn breakage or yarn slack, overlap, etc., which are well known, it is necessary to interrupt the process, particularly on the driven transport drum of the transport mechanism. The transport drum is therefore directly equipped with an overlap detector that cooperates with a switching device to close the drive unit. An overlap detector is disposed in the gap between the two rollers, the detector being fixed at one end of the detector at a short distance from at least one of the drum housings of the rollers. The overlap detector is connected to the switching device via an actuator. When the overlap detector 5 200804163 is moved, a switching pulse is triggered to turn the driving device off. However, the basic disadvantage of using this type of overlap detector mechanically in the transport mechanism is that after one of the yarn overlaps around the transport roller is detected, the long switching time and signal transmission path Putting 5 results in a relatively long reaction time until a drive is turned off. Especially at higher guiding speeds, relatively large yarn overlaps are formed very quickly around the transport roller. Especially when considering the direct drive of the transport roller, even before the shutdown, the overloaded drive will be overloaded. In addition, this type of closing system has a very complicated construction, and the mechanically generated signal is converted in a switching device and supplied to a control device through a line to actuate a small yarn drum to interrupt the process. DE 2 229 801 A1 discloses a conveying mechanism for directly dispensing a small drum of yarn during the running of the yarn. The yarn small roller can be activated by a switching device that cooperates with an overlapping detector. For this purpose, the overlapping pickers are assigned to at least one of the rollers of the transport mechanism. When a yarn overlap is formed around the drum of the transport mechanism, the front yarn drum will be actuated thereby causing the overlap detector to be triggered so that no overlap of (four) steps occurs on the driven drum . Therefore, although the increased overload state formed by the weight 4 of the assigned drive unit 20 can be effectively avoided, the defective portion is inevitably elongated in order to eliminate the interruption of the yarn overlap. Since it is often necessary to stop the drum in order to eliminate the yarn overlap, the closing of the drive must be carried out subsequently. [Picture] 6 200804163 SUMMARY OF THE INVENTION It is an object of the present invention to design a universal type of wheeling mechanism that avoids overloading of the electronic drive under any operating conditions. The object of the invention also provides a transport mechanism which can be used separately as a structural unit for guiding the yarn with high operational reliability as a textile machine. This object is achieved according to the invention, since when a contact switch is placed in the power supply line connected to the drive and the drive has at least one switchable interrupt contact point for interrupting the power supply of the drive, the cut A 10 change device is formed. The provoked improvements of the present invention are defined by the features and feature combinations of the scope of the secondary patent application. The present invention circumvents the currently known system that utilizes an overlay detector to signal the formation of an overlap to generate a control pulse control by the switching device - a drive is turned off, or preferably, the entire processing station is actuated . In contrast, the invention follows a completely new approach because the signals triggered by an overlap on a roller are used directly to interrupt the power supply of the drive. A very fast, no-delay shutdown of the drive is thus achieved. The control methods required for the previous manufacturing and subsequent assembly of the process were triggered only as 20 tracking. This type of control command can be triggered, for example, by a control device assigned to the drive device and recording a power failure on the drive device. An improvement of the present invention is that it provides a drive unit that is a three-phase current motor that is directly coupled to the transport drum. In particular, it can be utilized to form a small structural unit that can be used separately on a textile machine. Therefore, the overload of the three-phase motor can be avoided in the event of yarn overlap formation on the drum of 200804163. In order to ensure that the power supply is interrupted in a continuous and unambiguous manner, according to a preferred refinement of the invention, the contact switch is designed in a preferred manner to provide a circuit breaker for each of the phases of the power line.

The overlap detector is fixed at its free end, and it has = rare - cooperation with the contact switch Cam. 15 words; ^ test phase direct wheel off _, its transport roller is connected in the axial direction - electric ride, the switch shaft is difficult to be rotated, and the t-starting is broken and guided in the parking position and - Mode between off positions = axially parallel to the transport roller. The parking position forms an electric ... to the normal operating position of the power supply: for the spring - ": the change of the y-axis is _ axis t movement is broken overlap, the device is triggered, according to the invention, there is an improvement, overlap The detector is formed by the switching lever of the end, and the opposite end has a grip to - and the fineness of the transport roller, the detector end is rotated by the preferred drum, so that the tilt angle is positioned. The transition to the direction of rotation of the knife and the vehicle and thus the position of the stop position 20 200804163 to the -II lock position is predetermined. In addition, the overlap detector is designed such that the switch lever has an overlap detector At the same time it is used as a special advantage of a manual switch that closes the transport mechanism. This design is better used in the transport mechanism driven by the Xuxi-group rectification. Although it is controlled by 5 groups, each treatment is handled separately. The stations can thus be switched independently to on or off. For the sake of safety and for the advantageous operation of the transport mechanism, the improvement of the invention is preferably provided for use in a textile machine, in which a transport roller, a guide roller The three-phase motor and the switching shaft are fixed to a flat-plate carrier, and the drum housings of the 10 cylinders and the overlapping debt detectors fixed to the free ends of the switching shafts are arranged on a front side of the switching shaft. The required components are thus separated for easy handling by an operator. In production, yarn processing and further processing, it is customary to use a textile machine having a plurality of processing stations. Thus, for example, in the - false twist yarn 15 tissue manufacturing process More than two hundred workstations are used in a textile machine. In order to achieve a simple and cost-effective transport mechanism concept, the improvements of the present invention have proven to be particularly suitable for use on a three-phase motor that is configured to prevent overheating. The transport mechanism, the temperature protection device cooperates directly with the contact switch. Therefore, an overload condition that may occur on the three-phase horse 20, for example, due to an operation error or other error, can also be avoided. A comparison of the transport mechanism according to the present invention In a good design, the temperature protection device has a stress deflection device that is tightly coupled to the switching shaft to actuate the contact switch. In this example The deflecting device cooperates with a temperature sensitive protective device to release the prestressing force, and the released deflecting device generates an upward torque 9 200804163 to rotate the switching shaft. In this example, the bimetal can be used as a protective device. In order to release a pre-stress when the size of the deflecting device is changed. However, for a protective device formed of a fusible plastic component, it is also possible to shift the stress-biasing device at a specific temperature at which the motor is overheated.

A side view of one exemplary embodiment; FIG. 6 is a schematic view of a rear view of another exemplary embodiment of a wheeling mechanism according to the present invention. [Embodiment] 10 200804163 DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Sections 1 and 2 illustrate a first exemplary embodiment of a transport mechanism in accordance with the present invention in multiple views. In this example, Fig. 1 schematically shows the transport mechanism in a side view and Fig. 2 shows the transport mechanism in a front view. Since , 5 does not have a clear reference to one of the diagrams, the following description applies to both schemas. The exemplary embodiment has a transport roller 1 and a guide roller 2 located a short distance from the transport roller. The guide roller 2 is rotatably supported by a shaft 5 on a carrier 22. To this end, the carrier 22 has a first load point 10 21·2. The transport drum 1 is connected to the three-phase motor 6 via a drive shaft 3. The drive shaft 3 is fixed to the intermediate portion of the carrier 22 between the transport roller 1 and the three-phase motor 6. For this purpose, the carrier 22 has a second load point 21.1. The transport roller 1 and the guide roller 2 are thus arranged on the front side of the flat carrier 22. A three-phase motor 6 connected to a power source via a power supply line 7 is placed on the rear side of the carrier 22, and will not be described here. ® ' On the front side of the carrier plate 22, an overlap detector 8 is assigned to the transport roller 1. The overlap detector 8 is fixed at a small distance from the drum housing 4 of the transport roller 1 by a detector end 9. The distance between the drum housing 4 and the detector end 9 is guided by the drum housing 4 with a yarn that bears the circumference of the transport drum 在 without being in contact with the detector end 9 be chosen. Only in the case where a large number of yarns are continuously traversed on the drum casing 4 and stacked on each other and placed very quickly, the conveyed rolls are caused in the event that the yarn rolls are formed on the circumference of the conveying roller W and the yarn is wound. The circumferentially guided yarn blood overlaps the detector end 9 of the debt detector 8 for contact. In this case, the movement of the end of the bow 9 200804163 == is mechanically converted by the actuator 11 to switch into the connection 2 to interrupt the power supply. For this purpose, the contact switch 13 is placed in the power line 7 of the phase motor 6. The axis 12 of the axis 12 is shown in the example of the actual implementation of the switch. The overlap maker 8 is fixed (four) to the free end of the shaft 12. #, 2 is substantially axially parallel to the transport roller and is coupled to the switching shaft 12 at the opposite end of the carrier 22 via a third negative switching κ, χ 钡 17 and a 。. 10 1 is a diagram explaining the switching portion 36 in cooperation with the contact switch 13, see the interpolation of Fig. 3 and Fig. 3, which shows a section of the contact switch 13 in the power supply line 7 - switching cam 27. Bu 2 2 And 27 3 are formed in the switch as it is touched. The switching cams 27. 2 and 27, 3 cooperate in each case with one of the circuit breaker contacts 14 of the switch. Thus, Figure 3 shows an example of a circuit breaker contact point 14 that cooperates with the cutting and camming. The circuit breaker contact point 4 has two magazine contact elements 丨 and 丨 5 2 which, in the described operational state, are fixed against each other with the contact ends. In this example, the elastic splicing = element 15.α 15.2 can be fixed against each other by spring prestressing: a spring, a contact 70 pieces 15.1 and I5.2 are assigned a power line 7 in each case. Phase only. In this case, the phase 16.1 is assigned to the magazine contact elements 151 and 15.2. As can be obtained from the description in Fig. 1, the power supply line 7 has all three phases 16·!, 162 of the three-phase motor 6 and 16.3. Therefore, each of the phases 16.1, 16.2 and 16.3 is referred to as a circuit breaker contact 14 by a method similar to that described in FIG. In the operational state depicted in Figure 3, the switching shaft 12 is in a parked position such that the cams 27·1 are not in contact with the spring contact members 151. The spring contact tl pieces 15 · 1 and 15 · 2 are closed so that the power supply of the three-phase motor 6 is ensured. In the event that a yarn overlaps and abuts the detector end 9 of the overlap detector 8 thereby causing a rotational movement of the switching shaft 12, the switching cam 271 is pressed in the direction of rotation as indicated by the arrow and pushes the spring contact. Element 151. The contact points between the spring contact elements 15.1 and 15.2 will be released due to the bias of the spring contact 10 丨5·1. The power delivered via phase 16.1 is therefore interrupted. In the same manner, all the phases of the power supply line 7 can be immediately interrupted after the yarn overlap on the circumference of the transport drum 1 is detected, so that the two-phase motor 6 loses power supply and decelerates without an open circuit. Only when the yarn overlap on the transport drum 1 is eliminated and the overlap detector 8 returns to its original 15 park position, the circuit breaker contact 14 is closed and the three-phase motor 6 is powered by the power line 7. Even in the case where there is only some slight movement of the detector end 9, a flash lock device 17 is formed on the switching shaft 12 in order to trigger the switching stroke on a switching shaft 12 and to make it as far as possible. In order to explain the latching device π, see Fig. 1 to Fig. 4, which shows a cross-sectional view of the switching shaft 12 in the region of the latching device 17. The switching shaft 12 has a collar 37 having a latching track 20 on the circumference, the f-shackle track 20 guiding the balls 18 carried by a spring 19. In this case, the latching lane 20 is shaped and shaped in this manner. After a first small angle of rotation has been exceeded, the flash lock device 17 triggers a torque assist action on the switching consumption 13 200804163 12 to reach a latched position. The switching shaft 12 is parked in the latched position and can be brought back to the parked position by manual guidance only. As shown in Fig. 1, the free end of the switching shaft 12 extending on the rear side of the carrier 22 is coupled to a temperature protection device 23. The temperature protection device 23 is placed directly adjacent to the two-phase motor 6 to detect the overload condition of the three-phase motor due to overheating. In the present exemplary embodiment, the temperature protection device μ is constituted by a biasing device 24 that is firmly coupled to the switching shaft 12. A prestressing device 25 acts on the deflecting device 24 and the bimetal tear is used as a protective device. In this example, in the case of an increase in temperature, the bimetal % can be changed to its shape. In the described condition, the pre-stressing device 25 is secured to a tensioned position via one of the free ends of the bimetal 26. For this purpose, the bimetal 26 is fixed to the deflecting means 24 with a fixed end. In the case where the three-phase motor is overheated and the ambient temperature continues to rise, in particular, the free end of the bimetal % changes in size. The dimensional change of the bimetal 26 is indicated by the dashed line of Fig. 5 . In this case, the free end of the bimetal % is moved away from a tensioned position and transferred to a relaxed position. The prestressing device 25 is released and the switching shaft is shifted from its parked position to the flash lock position via the (four) to the device % on the switching shaft. As a result, the circuit breaker contact point 位于 located on the contact open_ is switched by the switching of the 20-axis 12 switch 6 wheels 27 > 1 to 27 3 to interrupt the power supply. Therefore, the temperature protection of the other 'three-phase motor 6' is ensured. In order to produce on the deflecting means 24: a torque action 'a free tension end of the prestressing means 25 is supported at a fixed stop point 38 supported by the three-phase motor 6. In the dilute implementation of the first and second products, the overlay controller 8 is designed to be a switch bar 28 of 200804163. For this purpose, the overlap detector has an additional detection of the crying end 9, the grip end 10, so that the switching shaft 12 can be moved by the switching lever; the actuation is directed from the parked position to the _ position. Therefore, it can be realized by manually closing the three-phase motor 6. , #5 threat and - yarn overlap contact, in order to actuate the switching lever 28 in the direction of switching indicated by the - arrow, the detector end 9 of the overlap detector 8 is fixed in relation to the axis of the transport roller 1 - inclination. The inclination of the detector end 9 is directed to the direction of rotation of the transport roller 1 such that at the contact surface of the detector end 9, the latter is directed directly to the switching direction of the switching lever 28 to interrupt the supply of power. In this example, the switching shaft 12 is also transitioned from the parked position to the latched position by the aid of the latching device 。. Fig. 5 schematically illustrates another exemplary embodiment of a transport mechanism in a side view. The exemplary embodiment is essentially identical to the exemplary embodiment according to Figures 2 and 2, and thus only the differences will be described herein. In the exemplary embodiment shown in Fig. 5, the actuator 11 connected to the overlap detector 8 is designed as a rocker arm 29. The rocker arm 29 is rotatably fixed to the carrier 22 via a rotary bearing 31. In this example, the detector end 9 of the overlap detector 8 is arranged on one of the free ends of the rocker arm 29 on the front side of the carrier 22. The opposite end of the rocker arm 29 has a switching pusher 3〇 that is assigned to one of the contact breakers 14 of the contact 20 switch 13. Contact switch 13 includes a circuit breaker contact point formed by spring contact elements 15.1 and 15.2. Switching on the rocker arm 29 The push rod 30 is supported on the spring contact element 15.1. The movement caused by the overlap of a yarn on the overlap detector 8 which is located on the drum casing 4 of the transport drum 1 causes the rocker arm 29 to rotate relative to the rotary bearing 31. In this case, the switching pusher 15 200804163 rod 30 abuts the spring contact element 15·1 and releases the contact point between the spring contact elements 15 j and 15.2, and the connected power supply line 7 is thus interrupted. The rocker arm 29 is elastically tensioned so that the cantilever 29 is moved back to a parked position after the overlap on the transport drum has been removed. 5 A temperature protection device 2 3 acts on the contact switch! 3 contact elements 15.2. The temperature protection device 23 has a biasing device 24 and a prestressing device 25 . The deflecting means 24 is fixed to a U-shaped bimetal 26, and the prestressing means 25 is disposed in the u-shaped bimetal 26 in the form of a compression spring. The bimetal 26 is fixed to the 10 motor 6 by being fixed to a holder 39 formed of a heat conductor material. In the case where the two-phase motor 6 is overheated, the size of the bimetal 26 is deformed, and the legs of the U-shaped bimetal 26 are separated from each other, so that the prestressing device 25 presses the biasing device 24 to make the pressing spring contact member. Ϊ́5·2 separates the contact point η between the spring contact elements 15·1 and 15.2. This will cause the power of the -15 source line 7 to be interrupted. - Figure 6 shows another exemplary embodiment of a temperature protection device, and as can be understood, for example, the exemplary embodiment described in Figures 1 and 2, in this example, the deflection device 24 is a U-shaped design It has a spring leg 32 and a fixing leg 33. The spring leg 32 and the fixing leg 33 are commonly disposed on the switching shaft 12. 2〇 The spring leg 32 is tensioned with the fixing leg 33 via a fixing device 35. A fixing device 35, such as a cord or a wire, is fixed to the fixing leg 33 by a fusible plastic nail 34. Both the spring leg 32 and the free end of the fixed leg 33 are fixed in the vicinity of the three-phase motor 6. In the case where the periphery of the three-phase motor 6 is not allowed to overheat, the plastic nail 16 200804163 3 melts so that the fixing device 35 is released and causes the elastic nail η to leave the fixing leg 33 by the elastic force. In this case, the spring (4) pushes against the housing 40 of the three-phase motor 6 and causes a reaction moment on the fixed leg 33 to move the switching shaft 12 from the parked position to the π-lock position. This state is indicated by the dotted line of the sixth figure. This will cause the circuit breaker contact point 14 on the contact switch 13 to separate, so that the power supply to the three-phase motor is interrupted. Such transport mechanisms in accordance with the present invention are merely exemplary in the exemplary embodiments described in Figures 1-6 and may be modified in accordance with equally similar actuation design methods. Importantly, in this case, the switching action initiated by the overlap detection due to the overlap of the yarns is immediately transmitted and causes an interruption of the driving means of the rollers that guide the yarns to overlap. Delay times, in particular signal flow and complex control devices on the device, can therefore be avoided. The mechanically triggered action of the yarn overlap can be directly converted into a circuit interruption, thus ensuring a very fast closing and thus protecting the drive from overloading. 15 [Brief Description of the Drawings] Fig. 1 is a schematic side view showing a first exemplary embodiment of a wheeling mechanism according to the present invention; and Fig. 2 is a schematic view showing a front view of an exemplary embodiment from Fig. 1; 3 is a cross-sectional view schematically showing a contact 20 switch according to the exemplary embodiment of FIG. 1; FIG. 4 is a schematic cross-sectional view showing a switching shaft in a portion of the latch device of the exemplary embodiment of FIG. 1; Figure 5 is a schematic illustration of a side view of another exemplary embodiment of a wheeling mechanism in accordance with the present invention, 17 200804163.
