Abstract

Bobbin changing device in spinning and twisting machines having a support which extends along the length of the machine and is movable towards the machine and in vertical plane and provided with a gripper for eac of the spindles as well as a conveyor belt which has a carrier peg for each of the spindles is provided with facility for intermediate storage of bobbin cores. Intermediate storage means for the cores is disposed within the confines of the machine above the flange which supports the spindles.

Description

The invention relates to a device for detecting and inserting bobbins and tubes on spinning or twisting machines, a β beam arranged along a machine which is movable horizontally in the machine cross-sectional direction and vertically and provided with a gripper for each spindle, with a conveyor belt provided for each spindle with a mandrel, and with a device for clamping the tubes.

In a known device for replacing coils for cores in spinning and twisting machines, a mandrel (DAS · δ. 2 165 041) is arranged on the spindle bench for each spindle. These mandrels are used to interpose the tubes. A disadvantage here is that this arrangement increases the width of the device for detecting and inserting the coils and tubes and hence the space requirement.

It is an object of the invention to reduce the space required for the sensing and insertion device. coils and cores.

The technical object of the present invention is to reduce the width of the device for detecting and spooling coils and tubes.

According to the invention, this is done. This is achieved in that the device for interrupting the tubes is arranged over the spindle cover flange in the machine cross section.

The invention will now be explained in more detail with reference to the drawings, in which:

Giant. 1 is a cross-sectional view of an annular spinning machine in a schematic representation with components involved in the process of detecting and inserting coils and tubes, in a rest position; FIG. 2 is a top view of a part of the device for interrupting the tubes; FIG. 3 shows the components shown in FIG. 1 in the operating position; FIG. 4 is a cross-sectional view of another exemplary embodiment in the rest position; FIG. 5 shows the components shown in FIG. 4 in the operating position; FIG. 6 shows a cross-section of another embodiment in the rest position; and FIG. 7 of the component shown in FIG. 6 in the working position.

Spindles 2 are fastened to the spindle bench 1, each of which is provided with a cover flange 2 (FIG. 1). The spindles 2 receive the sleeves 6 and 6 respectively. spools 2 above the spindles 2 and e are thread guide flaps X pivotally mounted on carriers 6. Further, above the spindles 2, a stand 8 and a blower 2 ^{and a} creel 10 holding the bobbin 11 are arranged. The yarns 12 leaving the puller 2 are Under the spindles 2, a movable conveyor 13 is arranged parallel to the longitudinal of both machines and a mandrel 14 for each spindle 2 is located in the center of the conveyor belt 13. A shaft 15 is disposed on the machine. The slide cranks 16 are pivotable about a shaft 15 and connected to a carrier 17 extending along the machine. As a result, the carrier 17 is movable horizontally in the machine cross-sectional direction and eviale.

A gripper 18, which is designed as a pneumatically operated outer gripper, is arranged on the carrier 17 for each spindle 2. Between the thread guide flaps X and the stand 8 of the draw-in device ^{80 there} is a device 19 for interrupting the tubes 7, which is thus arranged over the machine cross-section above the cover flange 2 of the spindles 2. The device 19 consists of a guide rod 20. driven in a manner not shown, which is movable horizontally in the machine cross-section direction and provided for each spindle 2 with one mandrel 21 and one sliding chute 22 for the yarn 12 (Fig. 2).

The operation of said device is as follows:

At the time the tubes 8 are wrapped on the spindles 2, the components involved in the removal and insertion process of the bobbins ^{28 are} in the rest position (FIG. 1). During this time, the full coils 2 removed in the previous procedure for replacing the full coils 2 s and the empty tubes 6 are removed from the conveyor belt 22 and the tubes 14 are injected into the darkness 14. In this case, the conveyor belt 13 ae reaches the end position in which the mandrels 14 ^{8 on the} inserted tubes 8 are located below the spindles 2. When the wrapping of the spools 2 located on the spindles 2 is finished. the yarns 12 disposed between the coating device 2 and the yarn guide flap X are fed via a chute 22 from the region in front of the mandrel 21. The yarn 12 then grips the carrier with its grips 18, the sleeves 8 prepared on the conveyor belt 13 deviate from the machine and are guided upwardly around the spindle bench 1, tilting over the device 19 to fold and deposit the sleeves 8 on the mandrels 21 of the guide bar 20a. In a further sequence, the carrier 17 is moved upwards, the device 19 is brought to its starting position and the carrier 17 shows with its grips 18 coils fi. Then it detects the coil carrier 17 on the mandrels 14 of the conveyor belt 11, the guide rod 20 moves with its mandrels 21 through the spindles 2, the carrier 17 grips its sleeves 18 with the sleeve 4, the carrier 17 moves upwards, the device 19 and the carrier 17 removes the sleeves 4 on the spindles.

In another embodiment, the device 19 for interchanging the tubes 4 is in the rest position in the region of the creel 10 (FIG. 4). The device 19 consists of a plurality of arms 23, driven in a manner not shown, which are connected to a support 24 extending along the machine. A gripper 2fi is provided on the carrier 24 for each spindle 2, which is designed as a pneumatically operated outer gripper. The device 19 is pivotable in the cross-sectional direction of the machine.

The mode of action, if it deviates from the previously described embodiment, is as follows:

To clamp the tubes 8, the device 19 swings up from the creel 10 upstream of the spindles 2 and upwards after the tubes 17 (FIG. 5) have been taken over. When the coils fi are removed from the spindles 2 and lowered. on the conveyor belt 13 ,. the carrier 24 again deflects in front of the spindles

2. The grips 18 of the carrier 17 receive the sleeves 6 from the device 19 and set them on the spindles 2. The device 19, in turn, rotates to a rest position in the region of the creel 10.
