Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION This invention relates to a spinning factory,
The present invention relates to a lap bobbin wrap removal processing device for efficiently removing a residual wrap from a wrap bobbin that winds a ribbon wrap or a sliver wrap (hereinafter, simply referred to as a wrap).

[0002]

2. Description of the Related Art In a spinning factory, raw cotton is first opened by a kneading and blending device to remove impurities and form a sheet-shaped wrap. A so-called lapping machine is used in the final step at this time, and the manufactured wrap is wound up on a large-diameter bobbin (hereinafter referred to as a lap bobbin) called a spool for convenience of transportation to the next step. It is common to seek

In the carding process subsequent to the kneading cotton process, a sliver wrap machine or a ribbon wrap machine is used to make a sliver wrap or a ribbon wrap,
These are also wound around the lap bobbin and conveyed.

Since the lap bobbin used in these various steps is reciprocally conveyed between the steps and is repeatedly used, in order to mount it on a lap machine or the like and wind a new lap, a preparatory step thereof is required. As a result, it is necessary to completely remove the wrap remaining on the surface of the lap bobbin, and as a device for performing such a lap removing process, for example, a device using a combination of a draft mechanism and an air nozzle is known (special feature: JP-A-54-22528).

In this device, an unprocessed lap bobbin with a lap is held on a draft mechanism composed of a pair of parallel rollers and rotated in the unwinding direction of the lap, and at the same time, an air nozzle is tangential to the lap bobbin. By jetting out the air jet from, the remaining wrap can be exposed and rewound.

There is also known a device in which a rotary brush is pressed against the surface of the lap bobbin so that the lap on the lap bobbin can be mechanically stripped off (for example, Japanese Patent Laid-Open No. 3-30083).
79563).

[0007]

According to the former case of the prior art, since the lap bobbin is frictionally driven through the parallel rollers, its rotation is not always smooth,
In particular, when there is a large amount of lap remaining on the lap bobbin, there is a problem that it may be difficult to completely remove the lap on the entire circumference. Also, in the latter case,
Since the wrap is mechanically peeled off, the fibers constituting the wrap are seriously damaged, and there is an unavoidable problem that the quality of the product may be deteriorated when the collected wrap is reused.

Therefore, an object of the present invention is to combine a holding mechanism for holding a lap bobbin in the axial direction and positively rotating the held lap bobbin with an air jet type lap removing unit, thereby remaining laps. It is an object of the present invention to provide a lap removing processing apparatus for a lap bobbin that can reliably remove the entire amount of the wrapping fibers without damaging the fibers even if the amount is large.

[0009]

The structure of the present invention for achieving the above object comprises a conveyor for conveying a lap bobbin and an air jet type lap removing unit which are arranged on both sides of a rotary shaft with a swing arm. And a holding mechanism that is attached to one end of the swing arm and that holds and rotates the lap bobbin in the axial direction. The swing arm includes a wrap bobbin that holds the wrap bobbin via the holding mechanism between the conveyor and the wrap removing unit. The point is to move back and forth between them.

The wrap removing unit can have a hopper with an air nozzle, and the hopper can be connected to the wrap collecting box via an opening mechanism.

[0011]

According to the structure of the invention, the holding mechanism is
The wrap bobbin on the conveyor is axially held, and the swing arm can convey the held wrap bobbin to the lap removing unit via the holding mechanism. On the other hand, since the holding mechanism can positively rotate the held lap bobbin, the lap removing unit can reliably remove the laps on the entire circumference of the lap bobbin.

When the lap removing unit has a hopper with an air nozzle, the air nozzle blows an air jet against the lap bobbin on the hopper,
The wrap on the lap bobbin can be easily peeled off.

If the hopper is connected to the wrap collection box via the opening mechanism, the wrap collected in the wrap collection box is returned to the carding step or the lap machine step because the opened state is good. Can be easily reused.

On the other hand, the holding mechanism 20 can rotate the held lap bobbin LB by starting the motor 35 and rotating the spline shaft 21 via the chain 35c (FIGS. 1 and 2). The spline shaft 21 is
This is because they are rotatably supported via bearings 31b and 31b, and can be rotationally driven by the chain 35c via the chain sprocket 21c and the rear boss 21b. At this time, the spline shaft 21 can rotate relative to the bearing holder 24a and the cylinder 25 via the bearings 24, 24.

Further, the holding mechanism 20 reciprocates the held lap bobbin LB between the conveyor 10 and the lap removing unit 40 by rotating the swing arm 31 upward by about half a turn by the motor 34. Can be made (solid line and two-dot chain line in FIG. 3).

Therefore, first, the holding mechanism 20 closes the swing levers 22, 22, ..., Stands above the conveyor 10, and carries in the lap bobbin LB with the lap L via the conveyor 10 (see FIG. 1). Arrow K1 direction). Swing lever 2
The conveyor 10 is stopped at a fixed position where 2, 22, ...
When 2 is opened to the outside, the holding mechanism 20 moves the lap bobbin L
Since B can be held, the motor 34
To start the lap bobbin LB and remove the lap removing unit 40.
The upper part of the line (two-dot chain line in FIG. 3).

Subsequently, the motor 35 is started to rotate the lap bobbin LB, and the lap removing unit 4 is operated.
0 air nozzles 41a, 41a ..., 42a, 42a. At this time, the blower B2 of the lap collection box B is operated in advance and a downward air flow is formed in the hopper 41. The air nozzles 41a, 41a, ... While spraying an air jet over the entire length of the lap bobbin LB,
The wrap L on B can be peeled off in order and dropped into the hopper 41, and the wrap L dropped into the hopper 41.
Can be unraveled and opened by the air jets from the air nozzles 42a, 42a ... And can be recovered in the container B1 of the lap recovery box B via the air hose 43.

The lap bobbin LB on the lap removing unit 40 is supplied onto the conveyor 10 so that the winding direction of the lap L is counterclockwise in FIG. 3 (FIG. 5).
Further, the rotation direction of the lap bobbin LB by the motor 35 is also preferably set in the same direction (direction of arrow K2 in the figure).

Further, at this time, the air nozzles 41a, 41a, ... Inject air jets in the horizontal direction with respect to the lap L or slightly downward from the horizontal direction at substantially the same height as the axis of the lap bobbin LB. Good.

When all the laps L on the lap bobbin LB have been removed as described above, the air nozzles 41a, 41
, 42a, 42a ... stop their operation, stop the motor 35 to stop the rotation of the lap bobbin LB, and also start the motor 34 to rotate the swing arm 31 half a turn to move the empty lap bobbin. Move the LB onto the conveyor 10. Next, the swing levers 22, 22, ... Of the holding mechanism 20 are closed to release the holding of the lap bobbin LB, and the conveyor 10
Is operated in the direction opposite to the arrow K1 direction in FIG. 1, the lap bobbin LB can be carried out to the outside. Therefore, the same process can be repeated for the lap bobbin LB with the new lap L.

[0035]

As described above, according to the present invention, by combining the holding mechanism for holding and rotating the lap bobbin in the axial direction and the air jet type wrap removing unit, the holding mechanism is a wrap. By positively rotating the lap bobbin with a wrap that has been moved onto the removal unit, the lap removal unit can smoothly peel off the lap using its air jet, so that the wrap remaining on the lap bobbin can be removed. Regardless of the amount, the entire amount can be surely removed, and since the wrap is not mechanically peeled off, there is no possibility of damaging the fibers constituting the wrap, which is an excellent effect.
