Description

[Detailed Description of the Invention] 〓Field of Industrial Application〓 The present invention is directed to a yarn winding device, particularly a yarn splicing/dolphing truck that runs along a guideway provided along the back side of a yarn winding device, particularly a plurality of yarn winding units arranged in a row. The present invention relates to a thread winding device made by

During yarn winding work in one winding unit,
When the package cage is full, or when a natural yarn breakage occurs and a sign is posted to notify the operator, the splicing/dolphing cart must be stopped when the yarn is full. In order to
At the same time, a full winding indicator lamp for the operator is lit on the front of the winding unit to notify the operator of the occurrence of this situation.

〓Conventional technology〓 When the yarn spun by a spinning unit is wound into a package cage, the presence or absence of a slub is detected by the slub catcher, and when the presence of a slub is detected, the yarn is cut and After the part is removed, the thread is tied and the winding into the package cage is resumed. This operation is performed by a splicing and doffing cart running along the plurality of spinning units arranged in a row. In addition, if spinning is not carried out in a spinning unit due to, for example, a sliver getting entangled with the rollers of a drawing device, or for other reasons, and there is a natural yarn breakage in that unit, it is necessary to wind up the package of the unit. will be stopped. If winding is stopped due to such a reason, even if the moving yarn splicing/durfing cart stops at the unit concerned and performs the yarn tying operation, the thread will not break unless the cause of the yarn breakage is eliminated. No matter how many times you try to tie the thread, the knot will not be completed, resulting in wasted work. Therefore, when such a natural yarn breakage occurs, a sign is posted at that unit, and the yarn splicing/dolphing cart is not stopped at the unit, so that workers can find the sign and identify the cause of the yarn breakage. After correcting this, the yarn splicing/dolphing truck is stopped and the yarn splicing/dolphing truck is made to perform the yarn tying work. Additionally, a sign will be displayed when the cage is full.

With this kind of equipment, the operator cannot tell whether the yarn is broken or full just by looking at the sign, and the worker may accidentally press the re-drive button to return the sign to its original position even though the yarn is full. If it is returned to its original position, the splicing and doffing cart will stop at the unit and perform splicing work. If the yarn splicing operation is performed even though the yarn is stopped at full winding, the package will wind up extra yarn, and the yarn length of the wound package cannot be kept constant.

Furthermore, when the yarn is cut by the operation of the slab catcher, the yarn splicing/durfing cart is stopped by a separate mechanism in relation to the unit in question, but no sign is displayed.

〓Problems to be solved by the invention〓 In view of the above-mentioned points, the present invention aims to make it possible for the operator to clearly recognize the stoppage due to occurrence of natural thread breakage and the stoppage due to full yarn. In addition, it is an object of the present invention to enable display means for displaying the prefecture to be implemented without major modification of the device.

〓Means for solving the problem〓 A failure display means that operates whenever a failure such as natural thread breakage occurs in the winding unit and when the package of the unit becomes full;
A fullness indicating means is provided which operates only when the package of the unit becomes full.

〓Operation〓 During the thread winding operation in one winding unit,
When the package cage is full, or when a natural yarn breakage occurs and a sign is posted to notify the operator, the splicing/dolphing cart must be stopped when the yarn is full. In order to
At the same time, a full winding indicator lamp for the operator is lit on the front of the winding unit to notify the operator that this situation has occurred.

〓Example〓 Embodiments of the present invention will now be described with reference to the drawings.

FIG. 1 shows an example in which the winding device of the present invention is implemented in an air spinning device, which comprises a drawing device 1 for drawing a sliver S, an air spinning device 2 for spinning the drawn sliver S into yarn, etc. unit 3
Next, a winding unit 7 consisting of a delivery roller 4, a slab catcher 5, a winding member 6, etc.
One spinning winding unit 8 is provided, and a plurality of spinning winding units 8 are arranged in a row. In each winding unit 7, a winding member 6 winds up the package P, and when the package P is fully wound up, a yarn splicing/doffing cart 1
A yarn splicing/dolphing cart stop fullness indicator lamp 9' for informing the operator 2 and a worker fullness indicator lamp 9 for informing the worker of this are provided. Indicator lamp 9, 9'
As shown in Fig. 2, the light emitting part is the winding unit 7.
They are provided at two locations facing both the front and rear surfaces of the. The one facing the front is a fullness indicator lamp 9 for workers to inform the worker that the package cage is full, and the one facing the rear is a light emitting lamp for the yarn splicing/dolphing cart 12, which will be described later. When a detection member (not shown) provided on the yarn splicing/doffing truck 12 detects that the indicator lamp 9' is lit at the full capacity indicator lamp 9' for stopping the yarn splicing/doffing truck 12. Then, the splicing/dolphing cart 12 is stopped at the winding unit 7 whose indicator lamp 9' is lit.

On the back side of the winding unit 7, guideways 10 and 11 are provided along the spinning winding unit row 8.
A splicing/doffing cart 12 is provided which is guided by and reciprocates. The trolley 12 includes a doffing device 13,
A yarn splicing device 14 is provided. 15 is full,
Signs indicating no sliver, natural thread breakage, etc.
16 is a re-drive button for restarting winding after a failure such as natural thread breakage.

It is now assumed that the yarn Y spun by the spinning unit 3 is being wound up by the winding member 6 of the winding unit 7. When the package P of the winding member 6 becomes full, a mechanism (not shown) detects the full state and displays the indicator 15.
is taken out, the winding of the package P is stopped, and the indicator lamps 9 and 9' are turned on. Indicator lamp 9,
9' is lit toward the front and back of the winding unit 7, so the operator can see the indicator lamp 9 along with the sign 15. In this case, the sign 15 is displayed when the machine is fully loaded. Recognize that it has stopped and do not take any particular action to deal with it. On the other hand, the yarn splicing and doffing truck 12 moves along the guideways 10 and 11, and when it recognizes that the indicator lamp 9' is lit, it stops behind the winding unit 7 and activates the doffing device 13. Do a doff and move on to the next unit.

During spinning, if a natural yarn breakage occurs in the spinning unit 3 due to some reason such as the sliver running out or the sliver getting wrapped around the rollers and being cut, a sign 15 appears to alert the operator. Inform. However, in this case, the indicator lamps 9, 9' are not lit. Therefore, the operator determines the cause of the failure, takes measures to eliminate the cause of the failure, and then presses the re-drive button 16. As a result, the yarn splicing and doffing cart 12 stops relative to the winding unit, performs yarn splicing work, and resumes winding. In this case, the yarn splicing/doffing cart 12 will not stop unless the operator removes the cause of the failure and presses the re-drive button 16.

〓Effects of the invention〓 As mentioned above, the device of the present invention has the winding unit,
A failure indicating means that operates when a failure such as a natural thread breakage occurs or when the package of the unit becomes full, and a fullness indicator that operates only when the package of the unit becomes full. Since it is equipped with a display means, along with the signs that appear when the thread is full, there is no sliver, natural thread breakage, etc.
Furthermore, a full indicator lamp is displayed on the worker's side only when the tank is full, so that the worker no longer misunderstands whether the tank is full or other malfunctions occur.

In addition, for the full-fill indicator lamp, it is only necessary to branch out another lighting circuit toward the worker from the lighting circuit used as a signal to stop the yarn splicing/dolphing cart when the yarn is full. This goal can be achieved without the need for major modifications to the equipment.
