Definitions

  • the invention relates to a spinning machine, in particular a ring spinning machine in combination with a winding machine according to the preamble of patent claim 1.
  • JP-OS 57-161 134 it is already known (JP-OS 57-161 134) to use the trunnion slides used in the winding machine connected to the ring spinning machine also as empty tube feed means or full tube discharge means by this trunnion slide, which generally consists of a circular disc and a vertical one center pins arranged thereon are displaced in a guide rail running around the ring spinning machine, the diameter, in particular the length, of a pin slide being slightly smaller than the distance between two adjacent spinning positions.
  • the individual pin slides are in contact with one another and are pushed forward by exerting force on one or more pin slides, the thrust force being at least partially transmitted by the direct contact of the pin slides.
  • a conveyor device for such trunnion slides is also known from DE-OS 35 44 560.
  • a disadvantage of the ring spinning machine according to JP-OS 57-161 134 is that the sleeve journals are not exactly in alignment with the spinning positions if a group of journal carriages with empty sleeves on one machine side has been moved in front of the assigned spinning stations. Therefore, before the sleeve change can be made, a rake at right angles to the longitudinal axis of the spinning machine between the trunnion slides in the known ring spinning machine be pushed so that the distances between the adjacent sleeve pins are coordinated exactly with the distances between adjacent spinning positions.
  • a reciprocating rail or the like extending along the spinning positions is used, which can be moved with a guide rail
  • the peg slide interacts in such a way that these are gradually moved to the assigned spinning position. So that the trunnion slides are precisely aligned with the assigned spinning station, they must either have a length exactly equal to the distance between the spinning stations, or there are pawl-like locking elements on the reciprocating rail, which are located exactly at the distance from the spinning stations, so that the locking elements ensure an exact alignment of the trunnion slides with the assigned spinning station even when the holding sledges are not in contact with one another.
  • the aim of the invention is to create a spinning machine, in particular a ring spinning machine, in combination with a winding machine of the type mentioned at the outset, in the case of the tube changing position of the endless conveyor an exact alignment of the sleeve pin relative to the assigned spinning station is to be ensured without the need for expensive mechanical measures that are prone to failure and require special maintenance, such as the introduction of rakes or the arrangement of pivoting pawls.
  • the idea of the invention is therefore that drivers are attached to the endless conveyor in exact positioning, which only have to be held in entraining mechanical engagement with the trunnion slides in order to ensure an exact alignment of the sleeve spigot with the assigned spinning position in the sleeve changing position of the endless conveyor.
  • this intervention occurs automatically when the trunnion slides have been transported to the spinning station.
  • an exact alignment of the trunnion with the spinning stations is ensured without excessive manufacturing and maintenance work having to be carried out for this purpose, although the trunnion carriages customary in winding machines are also used for supplying and removing the sleeves from the ring spinning machine.
  • the attachment of the drivers on the endless conveyor in precise alignment brings the essential advantage that the trunnion slides only come into engagement with the drivers at the loading station.
  • the trunnion slides can easily be removed from the drivers, while the precisely positioned drivers remain unchanged on the endless conveyor, which is realized in particular by a vertically arranged steel belt.
  • journal carriages which are guided in groups in an unsynchronized manner one after the other in the winding machine, are exactly positioned during the transition to the spinning machine by being brought into engagement in a controlled manner with the precisely positioned drivers.
  • the full sleeve Aragenden trolley at the end of the spinning group in question are removed from their exact positioning on the endless conveyor and fed to the normal transport system of the winding machine, which operates in a completely different cycle than the ring spinning machine. There is therefore no need for a timing interface between the ring spinning machine and the winding machine.
  • the main advantage of the combination of the spinning machine according to the invention is to be seen in the fact that one and the same trunnion slides on the spinning machine are brought into exact alignment with the individual spinning positions using the simplest means, namely the precisely positioned carriers the normal, unsynchronized transport of consecutive tenon slides takes place within the winding machine.
  • both debris of the endless conveyor on a single machine side, expediently, according to claim 3, both debris are equipped with drivers and trunnion slides.
  • the endless conveyor is guided around two mutually opposite machine sides of one or more spinning station groups, so that the full sleeves (cops) on both sides of the spinning machine can be exchanged for empty sleeves.
  • the endless conveyor can be suitably moved forwards or backwards at times by half a division of the spinning position.
  • the arrangement of the additional pins on the driver is particularly advantageous because conventional pin slides can thereby be used.
  • the measure according to claim 7 is provided.
  • the endless conveyor can only be used for advancing, but not for carrying the trunnion slides be used.
  • the support rail according to claim 8 is preferably provided for carrying the trunnion slide.
  • the mounting rail can also perform the longitudinal guidance of the trunnion according to claim 9.
  • the driver has a pure drive function.
  • the pin carriage is additionally guided by the driver, for example by being in a snap connection with the latter.
  • the drivers hold the trunnion magnetically.
  • a buffer path is expediently connected between the spinning machine and the winding machine in order to take into account somewhat different working speeds of the two machines.
  • a predetermined supply of full sleeves or empty sleeves, which are arranged on journal slides, is kept available on the buffer sections. If a buffer section is full, the subsequent device can be switched off for a certain period of time. Conversely, the device supplied can be temporarily switched off by suitable switching means, for example working with light barriers, when there are no more storage sleeves on the buffer line.
  • suitable switching means for example working with light barriers
  • the full heads can be removed from the sleeve journal on one buffer section.
  • the trunnion slides are also removed from the buffer section, fitted with a new sleeve and then placed on the second buffer section again. Thanks to the monitoring according to the invention, pin slides with full cops are always supplied and the pin slides with empty sleeves are conveyed back into the ring spinning machine.
  • the buffer sections which are to be protected against fiber flight, can also ensure that the full sleeves (cops) are largely protected against fiber flight by rapid transfer into the buffer section.
  • the buffer zone at the exit of the ring spinning machine should have a capacity approximately equal to the number of spinning stations supplying it.
  • the gripper-free transfer of the trunnion carriage from the spinning machine to the winding machine or the buffer section and vice versa can expediently be carried out according to claim 13.
  • a particularly advantageous development of the invention is characterized in accordance with claim 18 in that the drivers are arranged on the endless conveyor with adjustable length.
  • the drivers are arranged on the endless conveyor with adjustable length.
  • the construction of the endless conveyor according to claim 19 is particularly advantageous in terms of construction and function.
  • Claim 20 characterizes a further advantageous variant.
