Description

DETAILED DESCRIPTION OF THE INVENTION The invention comprises a bobbin creel equipped with an operating device, in particular a piecing device, into which the roving bobbins are loaded via a bobbin carrier coming from a flyer roving machine and movable along the machine. Regarding spinning machines.

It is already known in the prior art to place the roving bobbins drawn in a flyer roving frame into a bobbin transport car, and to move this bobbin transport car to a spinning work position. At this spinning work position, the bobbin is taken out from the bobbin carrier,
It is either stored on the creel or directly attached to the creel when replacing a used roving bobbin. in this case,
It is already known to carry out the movement of the bobbin transport table automatically with a floor conveyor device. However, this work requires a lot of manpower and costs.

Furthermore, it is also known to provide spinning machines with working devices, for example devices for automatically eliminating thread breaks or so-called mobile blowers. These devices run along a ring spinning machine. This is because the working places of these devices are distributed widely along the machine, and they must work over the entire length of the spinning frame.

The object of the invention is to reduce the loading of intermediate bobbins coming from a flyer roving frame onto a spinning frame, to make it possible to do it at low cost and to make it at least quick and partially automated.

The above problems are solved by the present invention as follows. That is, the working device is equipped with a device for catching and moving the intermediate bobbin, and by means of this device, the paper-forming device takes out the intermediate bobbin from the bobbin carrier parked beside the spinning machine and moves it onto the bobbin creel. This problem is solved by configuring the system to carry it into the area and store it there. Therefore, the working device, for example a splicing device or a moving blower, takes on, as another function, the task of transporting the bobbins in the full tube from the stopped bobbin transport bin to the area of the machine reel. This preliminary work on the paper spinning machine is further simplified and facilitated.

In a further development of the invention, the roving bobbin can be placed by means of a working device on a mounting surface provided for working purposes on the bobbin creel.

According to a further embodiment of the invention, a storage position is provided in the area of the bobbin creel, which serves to accommodate the intermediate bobbin, with which it is possible to install a second roving bobbin with the TtK working device. After the spinning of the roving bobbin is completed, the full bobbin is inserted into the supply position in the creel by the worker.

In a further development of the invention, the working device is provided with a companion sensing element for detecting the storage position or the empty support surface in which the bobbin is to be loaded. As a result, the working device recognizes the empty storage position and attaches a full bobbin to this empty storage position.

The invention provides the advantage that whenever this operation is carried out, there is always a bobbin reservoir in the bobbin creel which serves as a working buffer.

According to another proposal of the invention, the spinning end position in the bobbin creel is equipped with sensing devices for sensing the roving bobbin that is about to finish spinning, and these sensing devices in the spinning end positions of the associated group are provided. is combined with a ft1Fi signal generator, which signals the storage belonging to the spinning end position of this group when the signal of at least one soon-to-be-coming roving or ginning is generated. The location is indicated to the Work II device as the storage location where the work must be done. As a result, the running shape and thread facing the bobbin are transferred to the working device, - the storage position 1f belonging to the trout spinning end position;
Provides an opportunity to install the intermediate bobbin of the K711 tube. The advantage of this arrangement is that the worker can know in advance when it will be necessary to replace the outgoing roving bobbin with a new intermediate bobbin.

A feature of the working device used in the present invention is that it is equipped with a device for taking out at least one roving bobbin from a bobbin carrier, storing it for transfer, and loading it onto a bobbin creel. .

The automatic mode of operation of the device completely frees the operator from the difficult and completely tedious activities of carrying side bobbins along the machine and lifting heavy intermediate bobbins to the height of the mounting creel. A bobbin carrier carries a large number of bobbins, for example 10 vertically erecting rows of 8 bobbins each, and the equipment for handling these bobbins is therefore relatively long without the need for operating personnel. It is possible to automatically load the ring spinning frame over time (e.g. at night or over the weekend?) in the presence of a continuous transport vehicle.

Since the working device is capable of storing a large number of roving bobbins, this working device is used for the rounding work phase from the taking-off work phase next to the roving bobbin transport vehicle to returning to the taking-up and paper-making east phase. As a result, it is possible to perform wrapping and loading of full intermediate bobbins at multiple positions on the ring spinning machine. With this mode of operation, the working device returns to the bobbin transport vehicle after each transfer of a full intermediate bobbin to the creel and there removes a new roving bobbin. Therefore, this working device can follow its main operation, for example, the operation of resolving a thread breakage, without being hindered. This is because this operation is interrupted only briefly in order to pick up a new roving bobbin from the bobbin carrier and to transfer this roving bobbin to the creel.

Therefore, an additional and non-living unit for removing and supplying the spinning bobbin is no longer necessary. Viewed from another point of view, this working device meets the demand for intermediate bobbins to be easily installed, which arises in the itinerant work under the continuation of the series of life fIIh according to the plan centered on the ring spinning machine. The bobbin is taken out from the storage of the roving bobbin that comes along with the roving bobbin and covered, thereby avoiding a work bottleneck caused by the removal of the roving bobbin.

Other advantageous configurations of the device and the detailed operating sequence thereof are set out in the claims.

The invention will be explained in more detail below with reference to embodiments illustrated in the accompanying drawings.

In the embodiment shown in FIG. 1, a ring spinning frame 1 is provided. This ring spinning machine is equipped with a bobbin creel 1' (No. 4 wA), which is not shown in detail.
This bobbin creel has a spinning position, generally a so-called suspension holder, in which a roving bobbin 6 is held for spinning operations. In the flyer roving frame 2, the bobbin carrier S is loaded with full roving bobbins and is brought to a defined intermediate position 3' beside the ring spinning frame 1. According to the invention, the roving bobbin 5' is moved by the working device 4.
The bobbin is removed from the bobbin carrier 3 at the position , and is fed into the area of the bobbin creel 1 ′, where it is placed on a mounting surface 5 provided for the bobbin. As working device 4, for example, a splicing device or a mobile blower can be used;
These devices are equipped with gripping elements and carrying elements detailed below for the roving bobbin. Accordingly, these apparatuses have the additional function of transporting a full bobbin from the bobbin transport car 5' into the bobbin creel 1' of the ring spinning frame 1.
4 is equipped with a sensing element (not shown in detail), for example a light beam barrier device, which detects an empty loading stage in order to prevent a roving bobbin from being placed on a loading stage on which a bobbin has already been placed. Sense the surface.

In the embodiment according to FIG. 2, the bobbin creel 1' of the ring spinning frame 1 is provided with a known suspension holder mounted on a bracket arm at a special storage location 7, for example the bobbin creel 1'. The roving bobbin 6 is brought to this special storage position 7.

From these storage positions, these roving bobbins are transferred into a bobbin creel by an operator at the spinning position when spinning of the roving bobbins is finished.

In this case as well, the working device 114 is connected to the opening/closing mechanism 9 by means of a sensing element in the form of a sensing arm 8 which delivers a switching pulse to this working position 4 via a conductor 10, for example at the position 1.
The empty storage position of i7' or 7' is recognized, and the spinning bobbin 6' of the III tube is installed. The advantage is that a working bobbin store is present on the storage location 7, which bobbin store guarantees uninterrupted operation of the four-spinning frame in the event of occasional production stoppages of the flyer roving frame.

In the embodiment according to FIGS. 3 and 5, the field 1 of the roving bobbin in the bobbin creel 1' of the ring spinning frame 1

This i-intermittent sensing device 12 is adjusted to generate a signal when the roving bobbin suspended thereon reaches a weight at which it still has a short time's worth, for example half an hour's worth of roving. There is. A storage location 7.7' and a signal generator 15 each belong to the field 011. This signal generator + fK indicates that the spinning bobbin is about to finish spinning, is given by the weight sensing device 12 via a lead 4114 emanating from the field; The style of (
generates a signal, e.g. in the form of a pin 15, which is perceived by the working device, and which signal is transmitted to the sensing lever 16 by the working device.
Based on this, it is assumed that the cough storage position is to be installed from K, and the storage d1 voltage intermediate bobbin 6' at this position f7' is installed. This structure has the advantage that it is possible to recognize where it is necessary to replace the spinning bobbin with a new intermediate bobbin even from a considerable distance away, without having to worry about the need for a new intermediate bobbin.

The working device 4 carries a limited stock of, for example, two to four roving bobbins, and supplements the light as it passes by the bobbin transport device i3', which has stopped stocking, or It is sufficient to carry out the work only after the reservoir has been exhausted in order to re-accommodate a new, complete reservoir.

It is also possible to operate a large number of ring spinning machines with one working device 4.

The working device 4 is provided with a device 21 .
