Description

Spinning cop and bobbin conveying system

The invention relates to a spinning cop and bobbin transport system for a winding machine with a plurality of work stations, comprising:

a feed path for feeding the spun cop arranged on the conveying device to the workstation,

a return path for removing the unwound spinning cop from the workstation,

-a plurality of transverse transport paths, each assigned to a workstation and connecting the feed path and the return path in the area of the workstation, wherein the inlet portion adjoins the feed path, and

-a plurality of conveyors, each assigned to a workstation and driven independently of each other for transferring a conveyor between a feed path and a return path, wherein the feed path extends along a transverse conveyor path such that a conveyor conveyed in a conveying direction along the feed path automatically enters an inlet portion without a conveyor.

Background

Modern winding machines typically have a plurality of similar work stations on which the yarn produced (e.g., on a ring spinning machine) is rewound onto a high capacity cross-wound spool. In order to ensure continuous operation of the workstation, it is necessary to continuously supply spinning cops to the workstation. For this purpose, a spinning cop and tube transport system of the type mentioned at the beginning is used, which transports the spinning cop to a workstation and removes the empty spinning cop.

Such a conveying system has, for example, in particular a conveyor belt guided along a guide rail, over which a conveying device circulates, which is designed as a conveying plate with a vertically arranged receiving spindle for receiving spinning cops. The spun tube yarn remains on these receiving spindles both during feeding and during unwinding, and the unwound spun tube yarn, i.e. the empty tube yarn, is subsequently removed.

The transport system comprises in particular a feed path and a return path, and a plurality of transverse transport paths extending between the feed path and the return path and assigned to the respective work stations, and within which the spinning cops are arranged in the unwinding position.

The feed path extends along the whole winder and supplies the individual work stations with the spun cops to be unwound. The transverse transport path ensures that the spun yarn to be unwound is fed to the workstation in the unwinding position and returns the unwound spun yarn via a return path which extends along the entire workstation of the winder, similarly to the feed path.

The feed path extends along the transverse conveying path such that conveying means conveyed along the feed path in the conveying direction automatically enter the inlet portions, which are devoid of conveying means of the respective transverse conveying path. In the case of a conveyor already arranged in the inlet section, the subsequent conveyor is thus moved further along the conveying path at these stations, wherein the conveyor arranged in the inlet section then acts as a guide element for the subsequent conveyor and causes them to be conveyed further along the feed path in the conveying direction. The conveyor device thus always enters in the conveying direction the first free entry portions of the work stations arranged one after the other in the conveying direction. Within the workstation, the conveyor is used to move the conveyor along a transverse conveying path, in particular to position the spun cop arranged on the conveyor in an unwinding position.

This embodiment of the spin tube and tube delivery system does not allow to selectively assign individual spin tubes to individual workstations. Forced processing of the spun cop from the prior art to the free entry portion at each workstation does not allow for processing of a single type of spun cop at one or more workstations, for example. The processing of special cop types at the work stations provided for this purpose cannot be carried out by means of the known cop and tube transport systems.

Starting from this, it is an object of the present invention to provide a spinning cop and tube transport system which allows an active allocation of the individual spinning cops to the individual work stations along the winding machine.

Disclosure of Invention

The present invention achieves this object by means of a spinning cop and tube transport system having the features of claim 1. Advantageous developments of the invention are specified in the dependent claims.

The spinning cop and tube transport system according to the invention is characterized in that the conveyor provided for transferring the transport means between the feed path and the return path is designed such that in a first rest position it releases the inlet portion of the transverse transport path relative to the feed path and in a second rest position it blocks the inlet portion relative to the feed path such that the transport means is transported further in the transport direction.

The basic function of the conveyor is to move the conveying device on which the spinning cop is arranged in the area between the feed path and the return path. This means that the conveyor means located in the inlet portion of the transverse conveying path are moved to the unwinding position by the conveyor and, after the unwinding process, are transferred from the unwinding position to the return path. According to the invention, the conveyor can be arranged in two rest positions and is designed such that in the first rest position it releases the inlet portion of the transverse path adjoining the feed path. That is, a conveyor moving along the feed path in the conveying direction automatically enters the released entry portion, from where the conveyor can move the conveyor in a transverse path. Furthermore, the conveyor is designed such that in the second rest position it blocks the inlet portion with respect to the feed path, whereby the conveyor moving in the conveying direction on the feed path passes the inlet portion of the transverse path, wherein the conveyor further conveys the conveyor in the conveying direction in the second rest position.

Embodiments of the spin-tube and tube delivery system according to the present invention may allow for selective selection of spin-tube yarns to be processed at various workstations. Since the conveyor may be arranged in the second rest position, the conveyor may be further transported at the respective workstation even if the inlet portion is not occupied by the conveyor. Thus, certain workstations may be used only for processing certain spun cops, so that the spun cop and tube transport system according to the invention allows different spun cops to be processed at a particularly provided workstation of the winder.

The positioning of the conveyor in the first or second rest position and thus the selection of the conveyor device to be received with the spun cop arranged thereon can in principle be carried out in any desired manner. For example, in the case of periodic feeding of different spinning cops via a central control device, the corresponding positioning of the respective conveyors can be carried out at the respective workstations, ensuring that they are selectively fed to the respective workstations.

According to an advantageous development of the invention, however, a first spin-tube identification unit is provided, which is connected to the control unit of the conveyor, arranged at the workstation, in order to position the conveyor in the first rest position or in the second rest position.

According to a development of the invention, the spun yarn approaching the respective workstation is identified by the first spun yarn identification unit. If the first spun yarn identification unit detects that the spun yarn approaching along the conveying path is not intended for processing at a workstation, the control unit of the drive unit controlling the conveyor will cause the conveyor to be arranged in the second rest position such that the spun yarn passes the corresponding workstation and is conveyed further along the conveying path.

On the other hand, if the first spin-tube recognition unit detects a spin-tube to be processed at the corresponding workstation, the conveyor is positioned by the control unit in a first rest position such that the spin-tube enters the inlet portion of the transverse path, and then the conveyor displaces the spin-tube from the inlet portion to the unwinding position. This embodiment of the invention makes it possible to identify the spinning cops assigned to the respective work stations in a particularly reliable manner and to guide them into the work stations accordingly.

According to a particularly advantageous embodiment of the invention, it is further provided that the first spin-tube yarn identification unit and the conveyor are connected to a central control device for transferring the conveyor. According to this embodiment of the invention, the positioning of the conveyor in the first rest position or the second rest position, and its subsequent activation for displacing the cop or the conveyor in the transverse path, takes place via a central control device of the winder, which is designed to control the drive of the respective conveyor in accordance with the identification data transmitted by the first cop identification unit. The central control device, the spinning cop identification unit and the drive unit of the conveyor are connected to each other via suitable data lines. The use of a central control device ensures in a particularly reliable manner the selective distribution of individual spinning cops to the individual workstations.

In principle, the arrangement of the first spun yarn identification unit at the respective workstation can be performed in any desired manner. However, according to a particularly advantageous embodiment of the invention, if the first spun yarn identification unit is arranged in the region of the inlet portion, it is made possible to detect the spun yarn approaching the respective workstation in a particularly reliable manner and thus to identify the spun yarn intended for processing.

According to another embodiment of the invention, a second spinning cop identification unit is provided, which is arranged in the unwinding position area of the workstation. The use of the second spun yarn identification unit makes it possible to verify the spun yarn fed to the workstation, so that it is possible to ensure particularly reliably that only those spun yarns which are intended to be processed at the workstation are processed at the workstation. Therefore, the failure detection of the first spun yarn identifying unit can be corrected by the second spun yarn identifying unit, thereby realizing high reliability of the detection of the spun yarn to be processed.

If the second spun yarn identification unit identifies a spun yarn that does not actually need to be processed, the spun yarn can be transferred again out of the transverse conveying path and into the feed path by the conveyor, wherein the control unit and/or the control device is designed for this purpose to transfer the conveyor in the direction of the return path and in the direction of the feed direction according to a particularly advantageous embodiment of the invention. By means of the movement of the conveyor directed counter to the direction of the return path, the spinning cop which was erroneously fed to the workstation can thus be fed again to the feed path, via which the spinning cop then enters the workstation provided for processing.

The design of the spinning tube yarn identification unit is in principle freely selectable. It is particularly preferred that they have an RFID reader that allows for particularly reliable identification.

The design of the conveyor is in principle freely selectable. According to a particularly advantageous embodiment, however, provision is made for the conveyor to have a conveyor wheel with at least one, preferably at least three, particularly preferably six grippers with conveyor bags which open in the region of the transverse conveying path in the direction of the return path for receiving the conveying means, in particular the guide bases of the conveying means designed as conveying plates. The embodiment of the conveyor as a conveyor wheel allows a particularly simple and compact embodiment of the conveyor, wherein the rotation of the conveyor wheel in the interaction of the conveyor bag with the conveyor device reliably transfers the conveyor device along the transverse conveying path. The shape of the transport bag is adapted to the design of the transport device or to the contact area of the transport device with the transport bag. The transport bag can thus have an opening, for example, adapted to the shape of the guide base of the transport plate, so that a reliable transfer of the transport device in the transverse path and in particular a positioning in the unwinding position is ensured.

The embodiment of the conveyor is in principle freely selectable such that it releases the inlet portion with respect to the feed path in the first rest position and blocks the inlet portion with respect to the feed path in the second rest position. In the case of an embodiment in which the conveyor is advantageously provided as a conveying wheel, it is provided according to a development of the invention that the gripper on the rear side opposite the conveying bag has a guide surface which defines the feed path in the region of the inlet portion in the second rest position. The rear side of the transport bag is thus not randomly configured, but is shaped such that it blocks the inlet portion in the second rest position and at the same time forms a guide surface on which the transport device on the workstation side slides and is thus reliably guided past the workstation in the transport direction.

According to a further embodiment of the invention, provision is made for the conveying wheel to be designed and/or arranged at the workstation so as to disengage from the conveying device arranged in the unwinding position. This embodiment of the invention ensures that after the conveying device is arranged in the unwinding position, even in the case of a backward displacement of the conveying wheel, no displacement of the spun cop arranged in the unwinding position occurs. Thus, after the spinning cops are arranged in the unwinding position, it is possible to receive additional spinning cops and store them at the workstation as spare spinning cops or return the erroneously conveyed spinning cops to the feeding path without changing the position of the spinning cops located in the unwinding position.

According to a further embodiment of the invention, provision is made for the outlet portion extending between the unwinding position and the return path to be designed such that the conveying device arranged in the unwinding position is transferred to the feed path by the conveying device moving to the unwinding position. This embodiment of the invention ensures in a particularly reliable manner that the conveying device with the empty spun cop is reliably transferred by the conveyor via the outlet portion to the return path by the subsequent conveying device.

Drawings

Exemplary embodiments are explained below with reference to the drawings. The drawings show:

FIG. 1 is a perspective view of a path of a spin tube and tube delivery system, and

fig. 2 is a perspective view of the path from the spin tube and tube delivery system of fig. 1 with the spin tube disposed on the delivery device.

Detailed Description

Fig. 1 shows a perspective view of a portion of a spin tube and tube delivery system 1 of a winding machine (not shown here). The spin-tube and bobbin transport system 1 has a plurality of work stations 5 assigned to the individual winding stations of the winding machine, on which the spin-tube 11 is unwound in an unwinding position 12 and the thread is wound onto cross-winding spools (not shown here) of the winding stations.

For supplying the respective work stations 5, the spinning tube and tube conveying system 1 has a feed path 3. The spun yarn 11 is guided on the conveyor 9 along the feed path 3 past the individual stations 5. The work stations 5 each adjoin the feed path 3 and the transverse conveying path 6 such that the conveying means 9 moving in the conveying direction T on the feed path 3 enter the transverse conveying path 6 through a free inlet portion 7 of the transverse conveying path 6, in which the conveying means 9 can be displaced, in particular can be conveyed to the unwinding position 12 by a conveyor designed as a conveying wheel 8.

In order to displace the conveying device 9 arranged in the transverse conveying path 6, the conveyor designed as a conveying wheel 8 has a plurality of grippers (enterainer) 13, by means of which the conveying device 9 with its spinning cop 11 arranged thereon is transferred along the transverse conveying path 6. For displacing the conveyor 9, the gripper 13 has a conveyor bag 14, the shape of which is adapted to the guide base 15. The guide base 15 is part of the conveying device 9 designed as a conveying plate 16 and also serves to rotatably mount the spinning cop 11 on the conveying device 9.

The conveyor wheel 8 may be arranged in a first rest position and a second rest position. In fig. 1, the conveyor wheels 8 are arranged in a second rest position in which they close the inlet portions 7 of the respective transverse conveyor paths 6, wherein a guide surface 18 arranged on the rear side 17 of the gripper 13 defines the feed path 3 in the region of the inlet portions 7, such that the conveyor means 9 moving in the conveying direction T slide on the guide surface 18 and are guided past the respective work stations 5 in which the conveyor wheels 8 are in the second rest position.

However, in a first rest position (not shown here), the gripper 13 is arranged such that the inlet portion 7 is released with respect to the feed path 3, so that the conveyor 9 moving in the conveying direction T enters the released inlet portion 7, from where it is then conveyed to the unwinding position 12 by rotation of the conveyor wheel 8.

The position of the conveyor wheels 8 in the first rest position or the second rest position is set by the respective drive means of the respective conveyor wheel 8, each conveyor wheel being connected to a central control device (not shown here). In this case, the positioning of the transport wheel 8 is carried out by signal inputs of the spinning cop recognition units (not shown here) connected to the control device, which detect the running of the spinning cop 11 towards the respective work station 5. On the basis of the recognition, the actuation of the control device via the respective drive means causes the transport wheel 8 to be arranged in the first rest position or in the second rest position.

In case a spun yarn 11 intended for processing is identified, the transport wheel 8 is moved to the first rest position such that the spun yarn 11 enters the inlet portion 7. On the other hand, the approaching spin-tube 11 is a spin-tube 11 which is not intended to be processed at the workstation 5, the transport wheel 8 is arranged in the second rest position, so that the spin-tube 11 passes the workstation 5.

After completion of the unwinding process of the spun yarn 11 in the unwinding position 12, the subsequent transport device 9 with the spun yarn 11 is moved by rotation in the direction of the transport device 9 in the unwinding position 12 via the transport wheel 8, wherein, under the interaction of the subsequent transport device 9, the transport device 9 in the unwinding position is transferred via the outlet portion 10 to the return path 4, through which the empty spun yarn 11 is then discharged from the winder.
