Description

[Detailed Description of the Invention] [Industrial field of application] In this invention, a plurality of calender rollers are arranged side by side so that adjacent calender rollers rotate in opposite directions. The present invention relates to a lapping device which is sequentially guided between the calender rollers and stretches the fleece through the calender rollers to finish it into a lap.

[Prior Art and Problems Thereof] In the spinning process, many short fibers are mixed in the sliver obtained in the carding process using a card device or the like, and the uneven fibers are caused by the mixed short fibers. Since the sliver is generated or the strength of the yarn is reduced, the sliver as described above has been conventionally guided to the carding step, and in this carding step, the short fibers mixed in the sliver are removed to obtain roughly the same result. It has been practiced to make fibers of a uniform length and completely remove fine contaminants and nep to make a clean and uniform sliver.

Here, in this carding process, in general, a plurality of slivers obtained in the carding process are arranged in parallel and guided to a sliver wrap device, and after the sliver wrap device finishes a wrap, the wrap is further formed. The ribbon wrapping device, and in this ribbon wrapping device, the overlapped wraps are stretched and finished into one uniform wrap, and then the wrap finished evenly in this way is applied to the combing device. So I tried to finish it again with a clean sliver.

Here, in the case where a wrap is manufactured by a sliver wrap device or a ribbon wrap device before being guided to the combing device as described above, conventionally, as shown in FIG. 2, a sheet-shaped fleece (2 ) Is guided to the fleece guide (6) through the press roller (5), and the fleece (2) is passed through the fleece guide (6) so that adjacent calender rollers (1) rotate in opposite directions. The rollers (1) are arranged so that they are supplied to a portion where the four calendar rollers (1) are arranged in the vertical direction in the apparatus shown in the drawing.

Then, while applying a load of 500 to 1000 kg from above the calender rollers (1) juxtaposed as described above,
The fleece (2) fed through the fleece guide (6) is guided between the top calender roller (1b) located at the top and the second calender roller (1c) located below the fleece guide (6), and the calender roller (1b),
Extend the fleece (2) through (1c) and then
Use this fleece (2) as the second calendar roller (1c)
As it rotates, it is guided between it and the third calendar roller (1d) located below it.
The fleece (2) is also stretched between c) and (1d), and this fleece (2) is guided between the third calender roller (1d) and the bottom calender roller (1a) located at the end. , The fleece (2) was further stretched between the calender rollers (1b) and (1c), and then, although not shown, the stretched fleece (2) was wound to form a wrap. .

However, as described above, when the tip of the fleece (2) is guided between the lower calender roller (1) and the mouth with the rotation of the calender roller (1), the fleece (2)
As the fenders (2) are gradually stretched between the calender rollers (1) and become flat, the fleece (2) does not flow well along the peripheral surface of the calender rollers (1), and the tip of the fleece (2) rotates. There is a problem in that the fleece (2) is separated from the peripheral surface of (1) and is not properly guided to the next calender roller (1), and the fleece (2) hangs down and is clogged in the lapping device.

Therefore, in the conventional art, as shown in FIG. 2, the guide plate (3) is arranged along a part of the outer circumference of the third calender roller (1d) that guides the fleece (2) between the fleece (2) and the bottom calender roller (1a). ) Is attached to the lower end of the clearer (7) that removes the fibers adhering to the peripheral surface of the second calendar roller (1c), and the fleece (2) is attached to the bottom calendar roller (1a) by this guide plate (3).
I was trying to get you to guide me.

However, even when the guide plate (3) is provided along a part of the outer circumference of the third calender roller (1d) as described above, the fleece (2) is provided with the calender roller (1) as described above. When it was stretched and flattened in order, the tip of the fleece (2) was not guided well between the fleece (2) and the bottom calender roller (1a), and the problem that it fell down and became clogged still remained.

Therefore, conventionally, the fleece (2) was controlled so that the fleece (2) was along the peripheral surface of the calendar roller (1) by appropriately spraying water on the peripheral surface of the calendar roller (1). ) The work of spraying water properly on the peripheral surface is troublesome, and when the amount of water sprayed is large, the fleece (2) may wind around the calendar roller (1) and the fleece (2) also becomes fuzzy. Further, there is a problem that the peripheral surface of the calendar roller (1) is rusted by this water.

Further, in the conventional lapping device, even if the tip of the fleece (2) is not guided well between the lower calender roller (1) and is hung down and clogged as described above, There is a problem that the lapping device may be continuously operated without noticing, the waste of the fleece (2) increases, and the lapping device fails due to clogging of the fleece (2).

[Problems to be Solved by the Invention] In this invention, a plurality of calender rollers are arranged side by side so that adjacent calender rollers rotate in opposite directions, and a sheet-shaped fleece is provided between the calender rollers. It is an object of the present invention to solve the above-mentioned problems in a wrapping device in which the fleece is stretched through the calender rollers to finish it into a lap.

That is, in this invention, in the lap device as described above, when the leading end of the fleece is guided to the next calender roller along with the rotation of the calender roller to perform kissing, the fleece is sequentially moved between the calender rollers. Even when stretched and flattened, the tip of this fleece is reliably guided along the circumferential surface of the rotating calendar roller between the next calender roller and the fleece from the calender roller. The first task is to ensure that it does not hang down and get stuck.

Even if the fleece hangs down from the calendar roller and becomes jammed, the lap device does not continue to operate as in the past, and there is less waste of the fleece and less failure of the wrap device due to clogging of the fleece. The second task is to do.

[Means for Solving the Problems] In order to solve the above-mentioned first problem, in the present invention, a plurality of calendar rollers (1) are arranged so that adjacent calendar rollers (1) rotate in opposite directions. 1)
The sheet-shaped fleeces (2) are arranged in parallel, and are sequentially guided between the calendar rollers (1), and the fleeces (2) are stretched through the calendar rollers (1) to form a wrap. In the finishing lap device,
Calendar roller (1) rotating the fleece (2)
In order to guide between the next calender rollers (1) along the outer circumference of the calender roller (1), at least the fleece (2) is guided between the calender roller (1) and the bottom calender roller (1a) located last, Along the outer circumference of the calendar roller (1), the bottom calendar roller (1
Guide plate (3) extended to near the contact point with a)
Was set up.

In order to solve the above-mentioned second problem in this invention, in the above-mentioned lapping device, the guide plate (3) along the outer periphery of the calendar roller (1) is attached to the calendar roller (1). It is provided so as to be rotatable with respect to 1), and a stop means (4) for stopping the lapping device when the guide plate (3) is rotated away from the outer circumference of the calendar roller (1). Of.

[Operation] Like the wrapping device according to the present invention, at least the bottom calender roller (1
With respect to the calender roller (1) which is guided between the guide plate (3) and the bottom calender roller (1a) along the outer circumference of the calender roller (1), the guide plate (3) is installed. If provided, even if this fleece (2) is stretched in order between the calender rollers (1) and becomes flat before being guided to the bottom calender roller (1a), the tip of this fleece (2) Guided by the guide plate (3), it is surely guided to the bottom calender roller (1a) as the calender roller (1) rotates.

Further, the guide plate (3) is rotatably provided with respect to the calendar roller (1), and when the guide plate (3) is rotated away from the outer circumference of the calendar roller (1), the wrapping is performed. If the stop means (4) for stopping the device is provided, even if the fleece (2) hangs down from the calendar roller (1) and becomes jammed, the guide plate ( 3) is pushed, this guide plate (3)
Rotates away from the outer periphery of the calendar roller (1), and the stopping means (4) stops the lapping device.

[Embodiment] An embodiment of the present invention will be specifically described below with reference to the accompanying drawings.

As shown in FIG. 1, the lap device according to this embodiment also has
Similar to the conventional lapping device, the sheet-shaped fleece (2) is guided to the fleece guide (6) through the press roller (5), and the fleece (2) is brought close to the calendar roller through the fleece guide (6). (1) In a portion where a plurality of calendar rollers (1) are arranged side by side so that they rotate in opposite directions, in the example shown in the figure, a portion where four calender rollers (1) are arranged side by side in the vertical direction. I was supposed to supply it.

Then, while applying a load of 500 to 1000 kg from above the calender rollers (1) juxtaposed as described above,
The fleece (2) fed through the fleece guide (6) is guided between the top calender roller (1b) located at the top and the second calender roller (1c) located below the fleece guide (6), and the calender roller (1b),
I tried to stretch the fleece (2) through the interval (1c).

Then, the fleece (2) stretched in this way is guided between the second calender roller (1c) and the third calender roller (1d) located below the second calender roller (1c), and the calender rollers (1c), ( I also tried to stretch the fleece (2) during 1d).

Further, the fleece (2) stretched in this manner is guided between the third bottom calender roller (1a) and the bottom calender roller (1a) located below the third calender roller (1d) as the third calender roller (1d) rotates. , (1c), the fleece (2) is further stretched and then, although not shown, the fleece (2) stretched in this way
I wrapped it up to make a wrap.

In addition, the second, third, and bottom calender rollers (1b), (1c), which guide the fleece (2) as described above,
In (1d), a clearer (7) is provided on the outer peripheral side where the fleece (2) is not guided, and each clearer (7)
Depending on the above calendar rollers (1b), (1c),
The fibers attached to the peripheral surface of (1d) were removed.

Here, in this embodiment, the fleece (2) is the last bottom calender roller (1d) located below the third calender roller (1d) as the third calender roller (1d) rotates as described above. When guiding it to the 1a), it extends as a guide plate (3) along the outer circumference of the third calender roller (1d) to which the fleece (2) is guided to the contact point with the bottom calender roller (1a), and further to this bottom. Use this guide that extends from the contact point with the calendar roller (1a) to the upper surface of the clearer (7) provided on the bottom calendar roller (1a) along the outer periphery of the bottom calendar roller (1a). The plate (3) was attached to the upper surface of the clearer (7).

Further, in this embodiment, the clearer (7) to which the guide plate (3) is attached as described above is rotatably provided, and the guide plate (3) is combined with the clearer (7). I tried to rotate.

Then, while the cam (9) is provided on the mounting shaft (8) of the clearer (7) to which the guide plate (3) is mounted, the guide plate (3) rotates in a direction away from the outer periphery of the calendar roller (1). At this time, a limit switch (4) for stopping is provided at a position close to the cam (9) as a stopping means (4) for stopping the lapping device.

Then, in the lapping apparatus of this embodiment, the tip of the sheet-shaped fleece (2) is supplied to the portion where the four calender rollers (1) are arranged side by side in the vertical direction as described above, and each calender is fed. When the roller (1) is rotated and guided to the lower calender roller (1) in order and kissing is performed, the fleece (2) is sequentially moved between the calender rollers (1) as described above. Even if it is flattened before being drawn to the bottom calender roller (1a),
The tip of the fleece (2) has the guide plate (3).
Guided to the bottom calendar roller (1a) with the rotation of the third calendar roller (1d), the fleece (2) is not guided to the bottom calendar roller (1a). The fleece (2) was almost never clogged between the bottom calendar roller (1a) and the guide plate (3).

In addition, when the tip of the fleece (2) is not properly guided to the bottom calender roller (1a) and hangs downward, and is jammed between the bottom calender roller (1a) and the guide plate (3), The guide plate (3) is pushed by the clogged fleece (2), and this guide plate (3) rotates together with the clearer (7) in a direction away from the outer periphery of the calendar roller (1). Due to the rotation of the cam (9) provided in (7), the limit switch (4) for stopping, which is provided in a position close to the cam (9), is actuated, and the wrapping device is stopped. .

Therefore, even if the fleece (2) is jammed between the bottom calendar roller (1a) and the guide plate (3), the fleece (2) continues to be fed, and a large amount of fleece (2) is wasted. And the fleece (2) was not clogged and the wrapping device failed.

Further, in this embodiment, the guide plate (3) is attached to the top surface of the clearer (7) provided on the bottom calendar roller (1a) as described above, and the fleece (2) is attached to the bottom calendar roller (1a). If there is a jam between the guide plate (3) and the guide plate (3), the guide plate (3) is rotated downward together with the clearer (7) so that it is laid down. It is now possible to easily guide and kiss between the third calender roller (1d) and the bottom calender roller (1a).

Further, when guiding the thus packed fleece (2) between the third calender roller (1d) and the bottom calender roller (1a) by hand, the guide plate (3) acts as a clearer (7). Since the limit switch (4) for stopping is activated by being tilted downward together, the lap device is not accidentally driven during the kissing work, and the kissing work can be performed safely. Became.

[Advantage of the Invention] As described in detail above, in the wrapping device according to the present invention, at least the calender roller that guides the fleece between the fleece and the bottom calender roller located at the end,
Since the guide plate is provided along the outer circumference of this calender roller up to the point of contact with the bottom calender roller, the fleece is stretched in sequence between the calender rollers and flattened before being guided to the bottom calender roller. Even if it is, the tip of the fleece is guided by the guide plate and is reliably guided to the bottom calender roller as the calender roller rotates.

As a result, in the lapping apparatus according to the present invention, when the calender roller is rotated and the leading end of the fleece is sequentially guided to the next calender roller for kissing, the fleece bottoms as in the conventional case. There was significantly less chance of clogging by hanging down from the calender roller without being guided well with the calender roller.

Further, in the wrapping device according to the present invention, the guide plate is rotatably provided with respect to the calendar roller, and when the guide plate is rotated so as to separate from the outer circumference of the calendar roller, the wrapping device is stopped. If a means is provided, even if the fleece hangs down from the calender roller and becomes jammed, the guide plate is pushed by the jammed fleece, and this guide plate rotates away from the outer periphery of the calender roller. Was automatically stopped by the stopping means.

As a result, in the case of this wrapping device, even if the fleece hangs down from the calendar roller and becomes jammed, the wrapping device does not continue to operate as in the conventional case, and the wrapping device is not wasted due to waste of the fleece or clogging of the fleece. The number of failures has decreased significantly.
