Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and apparatus for cutting sliver when replacing a can in a spinning machine.

Conventionally, in a spinning machine such as a comb, in order to cut the sliver stored in the can from the drawing section through the calender roller and coiler tube when exchanging a full can and an empty can, for example, two pairs of rollers are used in the sliver passage path. Various mechanical means are employed, such as providing a roller and cutting the sliver using the difference in circumferential speed of the roller. In this way, in the conventional device, a special mechanism must be provided for cutting the sliver, which makes the structure of the device complicated and expensive, and its installation position is limited, requiring consideration in design. This has had various problems, such as complicating maintenance work.

The present invention aims to solve the above problems of the conventional device, and according to the first invention of the present application, when changing between a full can and an empty can, the coiler tube is stored in the can from the calender roller through the coiler tube outlet. When cutting the sliver, the machine is stopped by regulating the coiler tube outlet to a predetermined position on the outer periphery of the full can, excluding the upper center, and then the full can is moved, and the coiler tube outlet is fixed at a predetermined position on the outer periphery of the full can, and then the full can is moved. In a method of cutting the sliver by creating tension in the sliver between two points with a nearby corner, the predetermined position is set at the predetermined position, and when the sliver is coiled clockwise within the can, the direction of movement when the full can is taken out is set at the predetermined position. When the sliver is coiled counterclockwise in the can, it is approximately 5 o'clock when the direction of movement is 12 o'clock when the can is taken out. o'clock to about 10 o'clock, and in the second invention of the present application, a full can detector for detecting a full can of sliver stored in a can from a calendar roller through a coiler tube discharge port, and a coiler If the tube outlet is located at the outer periphery of the full can, excluding the upper center, and the sliver is coiled clockwise within the can, the direction of movement when removing the full can is the 12 o'clock direction. When the sliver is coiled counterclockwise in the can, it should be positioned between approximately 5 o'clock and approximately 10 o'clock when the moving direction when taking out a full can is 12 o'clock. a position regulation detector that regulates the position of the machine; a control device that stops the machine in response to detection signals from both detectors; By adopting a configuration consisting of a moving means that applies tension to the sliver between two points with a corner near the exit, a special mechanism for cutting the sliver is not required.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a comb will be described in detail below with reference to the drawings.

In the figure, a gear end portion 2 is disposed on one side of a combing machine main body 1, and a coiler device 3 is disposed on the other side, and the coiler device 3 in the illustrated example is shown as having a two-delivery configuration. Coiler device 3
Candy box 4 located at the bottom of
A candate wheel 5 is rotatably supported inside via a bearing 6, and the upper surface of the candate wheel 5 is flush with the floor surface FL. With this configuration, the base plate 7 on the upper part of the library box 4 can be placed on the floor.
Can be used with FL. A trumpet 8, a pair of calender rollers 9, a coiler tube 10, and a coiler tube wheel 11 are provided on the upper part of the coiler device 3. It can be rotated in the direction of the arrow A through the cover. Further, a coiler wheel 11 is provided at the lower end of the coiler tube 10.
A discharge port 13 formed in the coiler wheel 13 communicates with the coiler, and a guide groove 13a is provided in the discharge port 13 on the side opposite to the rotation direction of the coiler wheel 11.
During normal coiling, the sliver S is accommodated in the cans FC ₁ and FC ₂ via the guide groove 13a.
(See FIG. 4) Furthermore, the coiler wheel 11 is provided with a detection piece 1.
4 is attached to the coiler plate 15 at a fixed position corresponding to this detection piece 14, and the discharge port 13 at the lower end of the coiler tube 10 is set at a fixed position.
That is, when the sliver S is coiled clockwise within the can, the moving direction when taking out a full can is from about 2 o'clock to about 7 o'clock, and when the sliver S is coiled clockwise within the can, the moving direction is between about 2 o'clock and about 7 o'clock. When coiling is clockwise, a position regulation detector 16 is provided, which includes a limit switch or the like, which regulates the position between about 5 o'clock and about 10 o'clock when the moving direction when a full can is taken out is 12 o'clock. The reason why the stop position of the discharge port 13 is regulated as described above is as follows.

That is, the sliver S located on the uppermost surface in the can is attached to the coiler tube 10 as shown in FIG.
When the discharge port 13 is between approximately 2 o'clock and approximately 7 o'clock (the range indicated by the Calendar roller 9 and discharge port 1
The tension generated in the sliver S with the corner part near 3 becomes particularly large, which causes the sliver S to
If the outlet 13 of the coiler tube 10 is located outside the range mentioned above, as shown in FIG.
Even if the full can is moved in the direction of the arrow), the sliver S
As the coiling unwinds and the tension loosens,
This is because the tension generated in the sliver S is not so large that the sliver S may not be cut. Therefore, the detection signal from the position regulation detector 16 and the detection signal from the full can detector 17, which is provided at a suitable location of the coiler device 3 and is composed of a limit switch or the like for detecting a full can of sliver S, are connected. sent to a control device (not shown);
Based on the command from this control device, the combing machine main body 1
It is designed to lead to a halt.

Next, full cans FC ₁ , FC ₂ and empty cans EC ₁ , EC ₂
The configuration of the automatic can exchange device 18 as a moving means for automatically exchanging cans will be explained.

An upright shaft 21 is rotatably supported by bearings 19 and 20 fixed to the base plate 7 and the coiler plate 15 of the coiler device 3, and a gear 22 fitted on the upper part of the upright shaft 21 is connected to the coiler. A gear 24 at the tip of a drive device 23 fixed on the plate 15 is engaged with the drive device 23 to transmit rotational force. Furthermore, rotary arms 26 and 27 in which can housing recesses 25 (four in this example) are formed are fitted at intermediate upper and lower positions of the upright shaft 21, and the lower rotary arm 27 is fitted with an appropriate number of can housing recesses 25 (in this example, four locations). A can guide roller 28 is rotatably arranged. On the other hand, a can guiding roller 30 is provided which is rotatable via a spindle 29 fixed on the base plate 7 at the coiling position (right side in FIG. 3). It is always biased in the can holding direction (in the direction of arrow B) by the wound spring 31.

In addition, in the figure, 32 is a can loading/unloading conveyor;
3 and 34 are detectors for checking the presence or absence of empty cans;
5 is a detector that confirms the completion of can exchange.

Subsequently, the operation of this embodiment having the above-described configuration will be explained.

Sliver S spun from the combing machine main body 1
is collected by the trumpet 8 of the coiler device 3, compressed by the calender roller 9, and coiled through the discharge port 13 below the coiler tube 10 and stored in the cans FC ₁ and FC ₂ . At this time, the sliver S is stretched in the opposite direction to the coiler wheel ₁₁ due to the mutual movement of the coiler wheel 11 and the cans FC ₁ and FC 2 rotating in the direction of the arrow A, but the guide groove 13a is formed on the opposite direction side. Since the sliver S is formed in this guide groove 13
It is smoothly accommodated in cans FC ₁ and FC ₂ via a. In this way, when the spun sliver S reaches a predetermined length and the cans FC ₁ and FC ₂ become full, this is detected by the full can detector 17 and the detection signal is input to the control device. A position restriction detector 16 is activated by the detection piece 14, and its detection signal is also input to the control device. However,
A command to stop the machine is sent from the control device, the combing machine main body 1 stops, and the rotation of the coiler wheel 11 is also stopped accordingly.
6 and stops at the predetermined position mentioned above. In this embodiment, the stopping position of the discharge port 13 is set so that the moving direction when taking out the full can FC1 is P in FIG.
The direction of movement when taking out the full can FC2 is the direction of arrow Q in Figure 2, so the discharge port 13 is located in the range from about 2 o'clock to about 7 o'clock when these directions are taken as 12 o'clock. I'm starting to do that.

Next, when the empty cans EC ₁ and EC ₂ are carried into the can storage recess 25 of the automatic can exchange device 18 by the can carry-in/out conveyor 32, this is detected by the detectors 33 and 34, and the full can is detected.
FC ₁ and FC ₂ are exchanged with empty cans EC ₁ and EC ₂ . That is, the drive device 23 of the automatic can changing device 18 is activated, the upright shaft 21 is rotated, and the rotating arm 2 is rotated.
6 and 27 rotate 180 degrees in the direction of arrow C to complete
FC ₁ , FC ₂ and empty cans EC ₁ , EC ₂ are moved in an arc. The sliver S in the full cans FC ₁ and FC ₂ is connected to the coiler wheel 11 and the coiler plate 1 by a spring (not shown) provided inside the can.
It is pressed against the bottom surface of 5, so it is full.
As FC ₁ and FC ₂ move, the sliver S moves to the corner 13b near the discharge port 13 below the calender roller 9 and coiler tube 10, as shown in FIG.
It is cut due to the tension generated between the two points. At this time, the sliver S is tensioned without loosening the coiling within the can, so that a particularly large tension is generated in the sliver S. Therefore, as described above, the sliver S can be reliably cut without using a special cutting mechanism. In this way, the full
When the automatic exchange with FC ₁ , FC ₂ and the empty cans EC ₁ , EC ₂ is completed, this is detected by the detector 35, and the operation of the combing machine main body 1 is restarted, and the empty cans EC ₁ , EC are replaced as described above. ₂ accommodates the sliver S. On the other hand, the full cans FC ₁ and FC ₂ are carried out to the next process by the can carry-in/out conveyor 32, and new empty cans are carried into the can storage recess 25.

In the above embodiment, the case where the can moves in an arc is described, but the present invention is not limited to this and can also be applied when the can moves in a straight line. In addition to the embodiment in which the sliver is accommodated in a can, it is also applicable to a planetary type coiler device in which the sliver is accommodated in a can in a stationary state.

As is clear from the detailed description above, according to the method and apparatus of the present invention, the sliver can be reliably cut by simply moving the full can when exchanging a full can with an empty can, and the sliver can be reliably cut by simply moving the full can. It has excellent features such as no special means for cutting is required, the structure is extremely simple, it is inexpensive, and maintenance work is easy.
