DE1096260B - Method and device for collecting and stacking ejected finished bobbins - Google Patents

Description

The invention relates to a method and a device for automatically transferring with a Sleeve or a coil core provided finished bobbins from an automatic winder into a magazine.

In a known device for transferring such bobbins from the automatic winder into a magazine an ejector is provided which engages over the fully wound coil, it in the axial direction stripped from the winding spindle and releases at the end of its stroke, so that it is in free fall on an elongated Catching tray arrives. The movable up and down and in to the axis of the winding spindle at right angles Catch tray is automatic when a sensor hits one that is already in the magazine Coil can be tilted to dispense the coil located in the collecting tray.

In another known device of this type, the magazine is on a mobile body guided collecting container with an insert shaft which is inserted into these and is divided into compartments, and there are chutes provided, along which the ejected reels in turn the same compartment are fed, and the mobile collecting body is after each compartment is completely filled Shifted by a compartment width, so that the now following coils are fed to the next compartment.

Another known device for depositing a completely wound bobbin has a collecting container for the individual ejected bobbin, which are equipped with special bobbin holding means in the form of grippers Is provided.

In each of these known devices so grip parts of the devices when transferring the Coils or when removing from the winding spindle on the circumference of the thread roll. The ones in the collecting bins lying coils touch each other with their windings. However, this is the case with sensitive people Threads and yarns are disadvantageous, since even the smallest damage to the fabric produced from them Product appear as a defect. Such errors or damage will be recognized after the Invention avoided in that the thread lap neither with a machine part during its transfer comes into contact with another coil.

A device for carrying out the method according to the invention with means for collecting the individually ejected finished spool, to lower it to the level of the top in one Magazine contained coil and for ejecting the coil in the magazine by tilting can preferably be characterized in that the coil supports both the catching device and the Magazine are designed as two-part shells, method and device

in such a way that they only attach the bobbins to the unwound Support the ends of the coil cores. This training avoids with certainty that the thread pack comes into contact with the bobbin supports, and the possibility of damage of the thread winding through the bobbin support is prevented.

According to a preferred feature of the invention, the spool supports of the magazine for the separate Storage of successive coils be arranged at intervals that are greater than that Diameter of the thread wrap. While in the known devices, the bobbins with their thread winding rest directly on the bottom of the collector body and also the walls of the same and optionally even touch the walls of individual compartments into which the collecting container is divided and which Thread lap of the adjacent bobbins touch each other, which leads to the transport of the full collecting container unavoidable chafing of the thread lap on the collecting container and against each other is by this training according to the invention, a separate storage of the individual finished coils in the Magazine, protected against damage, guaranteed.

The magazine can advantageously be provided with grooved strips in whose grooves the free coil core ends are recordable.

In the known devices, if provided, sensors for the purpose of automatic use Bringing about, lowering or lifting as well as tilting the safety gear also on the circumference of the thread wrap. The risk of damage to the thread roll by such devices is increased preferably prevented according to the invention that the sensor to trigger the tilting process with the end of the bobbin core free of the thread lap of the uppermost bobbin contained in the magazine interacts.

An embodiment of the invention is described below with reference to the drawing. In this shows

Fig. 1 is a side view schematically showing the essential parts of the device according to the invention represents

Fig. 2 is a front view of Fig. 1, partly in section,

Fig. 3 is a partial view of the parts shown in Fig. 2 on an enlarged scale.

A completely wound bobbin 10 is held between the winding head 11 and the counter holder 12, directly before it is released in a known manner by pulling back the counter holder to the right. Under the bobbin guides 13 and 14 are arranged so that only the ends of the yarn and not the Winding of the bobbin itself when the bobbin is ejected. Under these guides two rockers 15, 16 are arranged, which catch the coil and hold it only at its core ends. These rockers are mounted on a crossbar 17, which can be pivoted with their ends in with Nut thread provided bearings 18, 19 is mounted, which in turn sit on guide spindles 20, 21, the wear at their lower ends bevel gears 22, 23, which mesh with bevel gears 24, 25 on a common Wave 26 standing. A sheet metal 27 is connected to the bearing 18 and carries a guide sleeve 28, which runs on the lead screw 20. This guide sleeve carries a three-armed lever, its Arm 29 acts as a sensor and the arm 30 of which is connected to the rocker 15 via a link 31.

As can be seen from Fig. 2, a frame-like, rectangular-shaped magazine 32 is next to the path of the Swing 15, 16 arranged. This magazine slides in upper and lower guide rails 33 and has a plurality of inclined recesses 34 capable of receiving the ends of the spool cores, to store the bobbins. At the head of the magazine there is a slot 35 for the feeler arm to pass through 29 provided. The third arm 36 of the three-armed lever is provided with a pin 37 with a fixed curve 38 can cooperate to return. Next to the magazine is a mounted in the vertical direction movable rod 39, which has upper and lower pins 40 and 41, which are able to come into engagement with a stop 42 on the sheet metal 27. With the An auxiliary thread guide 43 and scissors 44 work together on the winding head.

When operating the device, if the winding the bobbin 10 is finished by an automatic mechanism of the winding head in a known per se Way stopped and the counter holder 12 moved so that it releases the coil. The coil falls between the guides 13, 14 through until their ends get into the vibrations 15, 16. The guides ensure an accurate location of the coil so that the winding does not come into contact with any part the machine comes. Immediately after the coil has reached its rest position in the rocker the auxiliary thread guide 43 is pivoted to the left, whereby it moves the thread running from the bobbin to the thread guide S and feeds it into the scissors, which are then used to cut the yarn. Of course, a new bobbin core has now been inserted into the winding head in a known manner, who picked up the thread before the cutting process was carried out. The automatic one The machine's mechanism then causes the new bobbin to be wound. These last mentioned Operations are of course common in automatic winding machines.

Simultaneously with the start of the winding of the new bobbin, the drive mechanism for the common shaft 26 and thus automatically set in motion for the guide spindles 20 and 21, so that the rockers 15, 16 are lowered relative to the magazine 32. Assumes that the magazine is empty, nothing happens until the bottom of the web is reached and the feeler arm 29 strikes the lower frame part of the magazine and activates the linkage 30, 31, which

^a 5 has the effect that the rocker tilts and releases its coil into the lowest recess in the magazine. The rocker continues its way down until the stop 42 strikes against the lower pin 41 and moves the rod 39 in such a way that it activates the reversing mechanism for the drive. The rocker is then moved back into the uppermost position, and during the last part of its movement the pin 37 comes into engagement with the cam 38, whereby the linkage and thus the rocker are returned to their original position. As soon as this has happened, the stop 42 comes into engagement with the upper pin 40, whereby the rod 39 comes into a neutral position and puts the drive for the rocker out of operation. This completes the cycle of movement.

During subsequent movements of the rocker bearing the coil, the feeler arm 29 is activated set when it touches the bobbin in the last recess, so that the delivery of the new bobbin takes place in the recess above. The swing arm naturally completes its way down to the lower one End and is then returned as previously described. This filling process of the magazine continues until it is full. A mechanism, not shown, can be provided with which Help the triggering of the tilting process by the sensor to fill the upper recess in the magazine at the same time causes the winder to be disengaged.
