Device for initiating a work cycle "in a feeder of a spinning or twisting machine

The invention relates to a spinning or twisting machine and in particular to a control system for initiating a work cycle in a feeder for operating the machine _{or the like}

The expression "lap" or "yarn lap ¹¹ used in the following description means the product of a bobbin" or. Twisting machine or other Sarn <= handling machine in wound form ₉ so that it can be moved from place to place ", the expression" Yarn ¹¹ should be understood in its general sense and refer to all types of thread = materials, and "indeed" both textile and other-kind,

The automatic operation of a spinning = or twisting machine is described in German patent P 16 85 884.7 disclosed These Patentsehriit relates check "to hawks a-service" or _o feed rotor which reciprocates on a strainer of bobbin-winding stations of Hasohine and forth "runs and a control system for initiating the operation of such a service station erforderndes mtafweiet specifically ₉ holds the Sufuhrläufer au at a certain station to a full, .dh- bespülten bobbin withdraw to put an empty winding core and initiate the bathe the winding core; in the event of an interruption of the thread running towards the bobbin, the feeder removes the partially flushed bobbin,

puts on an empty winding core and then initiates the winding of the thread »If the feeder runs the The station concerned cannot be operated satisfactorily capable, this station is shut down and the feeder then runs past this station without " hold up until the operator waits this station by hand and makes it ready for operation «

In short, the invention is directed to an operational electronic control device for an operating or feed runner running through the stations of a spinning or twisting machine if the station in question is in operating condition while another photocell supplies a signal or a display when the station in question requires operation or »maintenance o Depending on these two signals, a working cycle of the feeder is initiated» If the feeder stops the station not able to wait or operate satisfactorily »he automatically activates a roving« breaker, which interrupts the roving feed upstream of the drafting rollers of the station Interrupt the thread feed is in the position, no operating signal is supplied. The Bedienungsslgnai may be either a signal or an indication of a photocell ₀ due to the interruption of the tapered bobbin to the yarn = * yarn or a signal or be "a display of two Faotozellen deducted a bobbin.

The object of the invention is therefore primarily the sheep *

füng a novel improved control device for a yarn-handling machine, and specifically the creation a new and improved optiech electronics Control device eur control of a feeder one Spinning or twisting machine and in particular for delivery A notification when a station is in operating condition is located, and another display if this station requires operation, the duty cycle of a feeder being a function of these two displays is directed. One of the related inventions siel concerns the creation of such a device, in which the body display either means that a bobbin is ready for pulling off, but represents an indication for an interruption of the thread running on the bobbin.

According to Figo 1, a spinning machine 10 has a substructure 12 on which a number of spindles 14 are rotatably mounted, one at each of several stations 16 "Each spindle 14 removes a telescope" like a winding core pushed onto it, on which one Yarn thread to form a winding, such as a bobbin 18, can be wound up.

As explained in more detail in the patent cited at the outset, two parallel rails 20 are mounted on the substructure 12 for sensing the bobbins 18 and for operating the stations 16 requiring such an operation take up and guide, which is able to run back and forth along the rails at the stations 16 «, you slide wheels 22 are rotatably mounted on the slide body 26; more precisely, two of these wheels 22 are rotatably connected at the right end of the slide body 26 to a shaft 28 which is passed through bearings 30 provided in the slide body 26 Regieterhaltigen Zeiteteuer-Zahnrieiuen 3 ^ with dew drive wheel 36 of a mounted on the carriage body 26 reversible JJruckluft Mo tors 38 is connected.

Similarly Weiee the actuator 40 is at the left end of the rails 20 with another stop 46 in contact, wherein the direction of travel of the carriage 24 again reverses _o The formwork

In this way it is achieved that the carriage 24 is attached to the Stations 16 flushed bobbins A18 back and forth τor-

When the carriage 24 moves past a station 16, a photoelectric cell 76 supplies a work signal or an operational signal. The photo line 76 is rigidly attached as the carriage body 26 and is activated by a light beam 78 which is emitted by a lamp 80 mounted on the carriage body and thrown back by the roving interrupter 64 when the latter is pulled out in FIG marked operations position. This signal is initiated in connection with an operating signal or an operating display of the work cycle of the carriage 24. The operating signal can either be activated by activating a second photocell 02 mounted on the carriage body 26, which receives a light beam 84 sent by a lamp 86 fixed on the carriage body 26 and from the yarn Y at one point between the drafting rollers 52 and the lower ones yarn guide 56 reflected ffird and in this Wii · "a signal or · an ad for a thread break is _v or \ lepulenkörper by a signal Vo
