Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a preparation device for spinning spouts conveyed from a supply station to a preparation station upstream of a winding machine, and in particular to a device for preparing spinning spuns which are conveyed from a supply station to a preparation station upstream of a winding machine, and in particular to The present invention relates to a device for preparing a spinning tip for preparation by transfer to a shuttle or gripper and for feeding to a winder.

PRIOR ART AND PROBLEMS THEREOF It is known to prepare or finish rewound cops at a preparation or finishing station by means of fully automated winding devices. Such winders are usually equipped with a storage device in the form of a cot container or magazine. In the storage device, ready chips are stored until they are transferred to a winding station of a winding machine, which generally has several winding stations.
Preparation of cotsup is generally done by several different operations. In connection with the present invention, there is an operation of locating or selecting the spun yarn, grasping it, and feeding it to the yarn gripper or shuttle. As soon as the cot thread is gripped by a thread gripper or shuttle and detected by a thread detection device connected to the gripper, the thread with the thread is passed through the thread gripper and fed to the thread gripper magazine by means of a rocking device. be done. If the thread gripper does not grip the sprung thread, the rocking device moves and the sprung is ejected, for example into a container. The rejected tip is either prepared manually and placed in a tip magazine or returned to the preparation station, where the preparation of the tip, ie the thread detection and the delivery of the thread gripper, is repeated.

It is clear that in a more automated tip preparation process, the tips that are not yet ready in the preparation station are not simply removed, but are returned to the preparation station again. Thus, in the supply station, the newly fed and rejected cops are mixed and sent from the supply station to the preparation station, where the cops are subjected to the preparatory operations as described above.
The reason for returning the rejected cops to the supply station is as follows. Many chips that were unprepared during the first pass through the preparation station will be prepared during the second or, if repeated, third pass. Because of this significant increase in ready tips, it is desirable that unprepared tips are returned to the preparation station again.

However, one cannot ignore the fact that a small number of cops may not be prepared even after passing through the preparation station several times. These threads have winding defects that make it impossible to detect and grip the thread. As a result, the number of chips that are circulated from the supply station to the preparation station and from the preparation station to the supply station increases progressively, and the chips with these defects cannot be prepared at the supply station. Therefore, these tips should be removed to ensure that the appropriate tips are fed into the tip magazine. However, such a situation
That is, an increase in the proportion of unprepared cops is usually determined after a considerable period of time has elapsed, so that interruption of the winding operation of the winder is inevitable. Of course, circulating spuds can be removed manually, but this requires human supervision. It is also possible to monitor the circulation of unprepared chips by means of suitable devices, but this has the problem of requiring the use of very complex devices.

The object of the present invention is to solve the above-mentioned problems and to be able to manage unprepared chips circulating from a preparation station to a supply station without the need for manpower and without the need for complex and expensive equipment. Moreover, it is an object of the present invention to provide a spinning tip preparation device that can remove the unprepared tip at an appropriate time.

Means for Solving the Problems The object of the present invention is to provide a spinning tip feeding station and a spinning tip provided upstream of a winding machine to detect the spinning tip of each spinning tip and attaching it to a gripper. The method includes a preparation station for making preparations, a conveying device for sending the spinning tips from the supply station to the preparation station, and a separation station for sorting the spinning tips sent from the preparation station depending on whether the spinning tips are ready or not. The preparation station includes a counting and control unit that detects unprepared spinning tips, detects the number of spinning tips, and issues command signals based on these, and the separation station receives spinning tips from the preparation station. a supply line; a discharge line branching off from the supply line and forming a circulation path to the preparation station, a supply path to the winder side, and a discharge path from the spinning spun flow, respectively; and a discharge line from the supply line; and a deflector provided at a branch point to the line and for distributing the flow of the spinning spun tip to one of the discharge lines in accordance with a command from the counting and control unit, the counting and control unit controlling the preparation station. When the passing spinning tips are ready, they go to the supply path, and when they are not ready, they go to the circulation path, so that the proportion of unready spinning tips included in a predetermined number of spinning tips exceeds a predetermined limit value. Preparation of a spinning tip, characterized in that, when the limit value is exceeded, a signal is sent to the deflector so that unprepared spinning tips that have exceeded the limit value are distributed to the discharge path, respectively. This is accomplished by a device.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

The figure shows one part of the apparatus according to the invention, which supplies spinning tips in an irregular arrangement, sends them to a feeding station, then moves them to a preparation station, and returns unprepared tips to the feeding station. FIG. 2 is a schematic diagram of an example.

The illustrated apparatus comprises a supply station Z, a preparation station V and a separation station T. The preparation station V is, for example, an elevator 4.
The separating station T is connected to a feeding station Z by a conveying device F such as
It is equipped with

The supply station Z comprises a receiving device 1, such as a trolley or a truck, for receiving the chips in an irregular manner, and a feeding device 3. Supply device 3
Accordingly, the spinning tip 2 sent from the storage device 1
are aligned by an operation not shown in the figure and individually transported to the transport device F. Supply device 3
can have various structures, for example, can be equipped with a conveying and aligning device using a vibrating device.

The tip 2 is raised to the preparation station V by an elevator 4. The preparation station V is arranged a certain distance above the supply station Z, so that the preparation station V
The cots 2 from the feed station Z are sent through the cavity to a cotsup magazine 5 or to a discharge container 6 of a winding device (not shown).

At the preparation station V, the chips 2 are counted by a photoelectric counter. Further signals are issued after completion of the appropriate preparatory actions. This signal informs whether preparations such as detection and gripping of the spun yarn have been properly carried out, and is sent to the counting/control unit 9 via the connecting line 8. A signal from the counting and control unit 9 controls a controllable deflector 10 of the separation station T, which feeds the ready tips into the tip magazine 5. Unready taps are returned to the supply station Z for circulation or sent to the discharge container 6. The separation station T is connected to the preparation station V by a supply line 11. The supply line 11 is connected to the discharge lines 12, 13, 14 by the deflector 10.
is combined with The discharge line 12 (supply path) is connected to the magazine 5, the discharge line 13 (discharge path) is connected to the discharge container 6, and the discharge line 14 (circulation path) is connected to the supply station Z. The tip 2 returned to the discharge line 14 reaches the vicinity of the supply device. At this time, it is desirable to reach a spot near a tip that has not yet been aligned. However, instead of this, the discharge line 14 is connected to the storage device 1.
It can also be extended nearby.

The illustrated device operates as follows. Containment device 1
The cups 2 sent from the station are individually supplied to the preparation station V by the elevator 4, where they are counted and checked for readiness. When preparations are properly made at the preparation station,
A deflector 10 connects a supply line 11 to a discharge line 12, and the tip 2 is supplied to the tip magazine 5. If a lack of preparation is discovered, the deflector 10 connects the supply line 11 to the discharge line 14. Thereby, the unprepared chips are returned to the supply station Z and circulated. In the same way, all unprepared chips are sent to the supply station Z, and these chips are transported again to the preparation station V. Some of the tips 2 circulating in this manner are appropriately prepared during the second conveyance and supplied to the tip magazine 5. There are only a small number of cots that continue to circulate, and they can be prepared manually. Even if the amount of unprepared chips increases due to the increased operation, in order to prevent the preparation station V from being overloaded with a load that would make it inoperable, the preparation of other chips is not hindered. passing through the preparation station V at each predetermined time, depending on the time;
For each item, the ratio of ready tips to unprepared tips is determined to be appropriate.
For example, if n=8, the readiness status of 8 tips is checked, and if the number of unready tips exceeds a predetermined value such as 2 or 3, this value is exceeded. Instead of being circulated to the supply station Z, a number of tips are sent to the discharge container 6 by the changing movement of the deflector 10. Therefore, the number of tips that can be manually prepared will never exceed a predetermined number, and as a result, the preparation station V will not be filled with more tips than necessary. Adjustment of the number of such tips in the preparation station V can be carried out with a relatively simple control device. All prepared tips are sent to the tip magazine 5 of the winding device, and unprepared tips are sent to the supply station Z.
It is returned to and circulated. If the proportion of unready tips is too high, the number of unready tips exceeding the set value will be sent to the ejection container.

The device described above, which has a simple structure, can be applied to chips with a wide range of diameters and lengths without changing the mechanism.

Effects of the Invention As is clear from the above, the present invention includes a supply station, a conveyance device, a preparation station, and a separation station, and the separation station has a branch point from the supply line to the discharge line.
A deflector which directs the flow of spinning tips, i.e. the preparation contained in a predetermined number of spinning tips, into the supply path when the spinning tips passing through the preparation station are ready and into the circulation path when not yet ready. When the proportion of unfinished spinning tips exceeds a predetermined limit value, the discharge path is equipped with a deflector that distributes unprepared spinning tips that exceed the limit value, thereby reducing the need for human labor. It is possible to significantly reduce and manage the circulation of unprepared chips from the preparation station through the supply station without the need for more complex and expensive equipment, and to remove the unprepared chips at the appropriate time. It is possible to provide a spinning tip preparation device that can be used.
