DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a collection chamber for collecting fiber waste generated in a textile machine and then communicating with the collection chamber via a suction pipe and transferring the fiber waste to the collection chamber. And a suction force generating source for generating a suction flow for the same.

[0002]

2. Description of the Related Art A fiber litter collecting device for collecting lint, fuzz and the like generated in a textile machine and then storing the lint is provided with a lint collection chamber surrounded by a side wall of the device and a lint collection filter. ,
A filter for the lint collection chamber, a side wall of the lint collection device,
A fly waste collection chamber surrounded by a fly waste collection filter and a suction force generating source for generating a suction air flow for transporting fiber waste to the collection chamber are arranged in order from the upstream side of the suction air flow. Has been established. Here, the lint among the lint is collected in the lint collection chamber by passing through the lint duct communicating with the lint collection chamber by the action of the suction air flow. On the other hand, the fly waste penetrates the lint collecting chamber on the upstream side, and the fly waste is collected in the fly waste collecting chamber by passing through the fly waste duct communicating with the fly waste collecting chamber by the action of the suction air flow. I have. Therefore, by the above operation, yarn waste and fly waste can be collected separately, and the collected fly waste is reused as a raw material of spun yarn.

[0003]

By the way, when the fly waste is collected in the collecting chamber, the amount of the fly collected on the surface of the fly filter in the waste collecting chamber also increases. In addition, since the fly waste is uniformly deposited over the entire surface of the fly waste filter to block the air flow passage portion, the suction force from the suction force generating source is blocked by the fly waste filter, and the fly waste is returned to the fly waste collection chamber. Not only is the suction air flow for collecting the cotton weakened, but also the suction air flow for collecting the lint into the lint collection chamber on the suction air flow upstream side of the fly waste collection chamber is weakened, The collection efficiency of fiber waste is reduced.

[0004] Therefore, in order to remove the fly waste that blocks the entire surface of the fly waste filter, an operator periodically performs a fly waste cleaning operation. The larger, the longer. However, since the fly waste filter is formed on one plane, the time required for the fly waste to be uniformly deposited on the entire surface of the fly waste filter is short, and the fly waste must be cleaned frequently. there were. Therefore, it has been proposed to increase the surface area of the filter by providing the fly wool filter surface in a direction along the flow of the suction air. However, even if this filter is applied, it is difficult to increase the surface area of the filter. There was a limit.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has been made to increase the surface area (total) of a filter and to prevent fiber dust (fly wool) from being uniformly deposited on the entire surface of the filter. It is an object of the present invention to provide a fiber waste collection device that can lengthen the cycle of performing the collection work.

[0006]

In order to achieve the above object, according to the first aspect of the present invention, after collecting fiber waste generated in a textile machine, the fiber waste is collected via a collection chamber for storing the same and a suction pipe. A suction force generating source for generating a suction flow for conveying the fiber waste to the collection chamber, wherein the collection chamber is provided with a shaft of the suction pipe. It is characterized by comprising a front filter that is substantially perpendicular to the direction, and a side filter that is substantially perpendicular to the front filter, and a lateral ventilation space that communicates with the suction pipe is provided outside the side filter. In the present invention, the front filter includes a front filter substantially perpendicular to the axial direction of the suction pipe, and a side filter substantially perpendicular to the front filter, and a side ventilation space communicating with the suction pipe is provided outside the side filter. This facilitates the accumulation of fiber dust (wool fly) at the bent portion (intersection), that is, at the corner, of the front filter and the side filter substantially orthogonal to the front filter, thereby preventing uniform deposition on the filter surface.

According to a second aspect of the present invention, an upper filter is provided which is substantially orthogonal to the side filter together with the front filter, and an upper ventilation space communicating with the suction pipe is provided outside the upper filter surface. I have. According to the present invention, by providing the upper filter, which is substantially orthogonal to the side filter, together with the front filter, an upper ventilation space communicating with the suction pipe is provided outside the upper filter surface.
The total area of the filter is increased, and the required suction air flow can be maintained for a long time by intensively depositing fiber waste at the intersection of the three filter surfaces.

[0008] The invention according to claim 3 is characterized in that the inner peripheral surface of the suction tube is located inside a position facing the orthogonal portion between the front filter and the side filter. In the present invention, the inner peripheral surface of the suction pipe is located inside the position facing the orthogonal portion between the front filter and the side filter, so that the side ventilation space moves straight toward the suction pipe. To reduce the component of the suction air flow that flows through it, thereby increasing the horizontal component of the suction air flow from the collection chamber to the side ventilation space, and guiding the fiber debris to more easily accumulate at the intersections of the filter surfaces. Can be.

According to a fourth aspect of the present invention, the collection chamber includes a lint collection chamber having a lint collection filter on the upstream side of the suction flow, and collects lint via the lint collection filter. It is characterized in that it has a structure provided with a fly waste collection chamber connected to the chamber, and the lint collecting filter and the suction pipe are directly connected by the side ventilation space or the upper ventilation space. According to the present invention, in the collection chamber, a lint collection chamber having a lint collection filter is provided on the upstream side of the suction flow, and fly waste connected to the lint collection chamber via the lint collection filter. Assuming that the structure provided with the collection chamber and the lint collection filter and the suction pipe are directly connected by the side ventilation space or the upper ventilation space, the accumulation amount of fly waste in the fly waste collection chamber is increased. Also, since the suction air flow passes through the ventilation space (which flows without passing through the fly waste collection chamber) directly from the lint collection chamber to the suction pipe, it is possible to suppress a decrease in suction force in the lint collection chamber.

This is a duct that sucks and transports the lint generated at the time. A lint filter 6 is provided in front of the slack tube duct 4 and the lint duct 5. The lint filter 6 has a lint collection chamber ceiling 7, side walls 2 a and 2 b of the dust box 2, A lint collecting chamber 8 is formed by being surrounded by 2c (the dashed line in FIG. 1).

I have.

As shown in FIG. 2, the dust box top plate 2
e, an opening 18 b is provided, and an opening 18 a is also provided on the outer peripheral surface of the suction tube 9.
A bypass duct 18 formed in a substantially inverted U-shape is connected between a and 18b. In addition, in the vicinity of the opening 18a, the shielding plate 20a for the bypass duct and the shielding plate 2 for the suction pipe are provided.
A switching member 20 having an Ob and a suction pipe inner peripheral surface 9a are provided with a rod-shaped stopper / seal packing member 21. An inlet opening 18b of the bypass duct 18 is provided with a fly filter 18c. 20a and 20b
And are connected by a link. The dust box top plate 2e is provided with a flapper 23 so that the opening 3a on the outlet side of the fly waste collecting duct 3 can be shielded.

Here, when the bypass duct shielding plate 20a and the suction pipe shielding plate 20b of the switching member 20 are both horizontal, the bypass duct shielding plate 20 shields the opening 18a of the bypass duct 18. It has become. At this time, as shown in FIG. 2, the suction air flow is near the opening 3a of the fly waste collection duct 3, that is, the bypass duct 18
At the opening 18b at the entrance of the air, an air flow (arrow 36) directed to the suction pipe 9 via the bypass duct 18 and an air flow (arrow 3) directed to the suction pipe 9 via the fly waste collection chamber 24 described later.
7), but the opening 18 of the bypass duct 18
In a, since the air flow is shielded by the bypass duct shielding plate 20a, most of the air flows in the direction of the fly waste collection chamber 24 (arrow 37).

Next, as shown in FIG. 3, when the suction pipe shielding plate 20b rotates in the direction of the dust box 2, the bypass duct shielding plate 20a also rotates in the same direction. When the suction pipe shielding plate 20b comes into contact with the stopper / seal packing member 21, the opening 9a of the suction pipe 9 located on the dust box 2 side is shielded. At this time, as shown in FIG. 3, the suction force passing through the bypass duct 18 causes the flapper 23 to block the opening 3a on the outlet side of the fly waste collecting duct 3. Therefore, the suction air flow is applied to the fly waste collection duct 3.
From the opening 3a of the bypass duct 18, ie, the opening 18b at the entrance of the bypass duct 18, in the direction of arrow 37 ', and the flow in the direction toward the suction pipe 9 via the fly waste collection chamber 24 is blocked by the flapper 23. Then, as shown by an arrow 36, the air flows into the suction pipe 9 via the bypass duct 18. As shown in FIG. 3, after switching the flow path of the air flow to the bypass duct 18 and blocking the air flow to the fly waste collection chamber 24, the operator opens the opening / closing door (not shown) and opens the inside of the dust box 2. Cleaning work can be performed.

The side wall 2 of the dust box 2 on the side of the blower 35
At the end of the opening 9 b on the inlet side of the suction pipe 9 connected to the suction pipe 9, a front filter 29 for fluff is provided substantially vertically so as to be substantially perpendicular to the axial direction of the suction pipe 9. A side filter 30 provided substantially vertically so as to be substantially orthogonal to the front filter 29 and a top filter 31 provided substantially horizontally are provided. In the fly waste collection chamber 24, an intersection 32 is formed by the filters 29, 30, and 31 intersecting each other. Further, as shown in FIG. 1, the filters 29, 30, 31 and the walls 25, 26, 2
7, the lint collecting chamber ceiling 7 constituting the lint collecting chamber 8;
A fly waste collection chamber 24 is formed which is surrounded by the lint filter 6 and the side walls 2a to 2d of the dust box 2. That is, the front filter 29 forms one side surface of the fly waste collecting chamber 24, and the upper filter 31 forms the upper surface of the fly waste collecting chamber 24.

As shown in FIGS. 1, 4 and 5, outside the side filter 30 as viewed from the fly waste collecting chamber 24, the side ventilation between the side filter 30 and the side wall 2a of the dust box 2 is performed. A space 28 is formed. The lint filter 6 is directly connected to the inlet-side opening 9 b of the suction pipe 9 via the side ventilation space 28. That is, the side ventilation space 28
Thus, an air flow directed toward the suction pipe 9 acts on the lint collecting chamber 8 without passing through the fly waste collecting chamber 24. An upper ventilation space 33 is formed by being surrounded by the upper filter 31, the dust box top plate 2 e, and the wall 25, and the upper ventilation filter 33 allows the upper filter 31 to have an opening 9 b on the inlet side of the suction pipe 9. Is in communication with However, in the present embodiment, the lint collecting chamber 8 is directly connected to the inlet-side opening 9b by the side ventilation space 28 without passing through the fly waste collecting chamber 24, and the upper filter 31 is formed by the upper ventilation space 33 so that the upper surface filter 31 is a suction pipe. 9 communicates with the opening 9b on the inlet side, but on the contrary, the lint collecting chamber 8 is formed by the upper ventilation space.
And the opening 9b on the inlet side without passing through the fly waste collecting chamber 24.
And the upper surface filter 31 by the side ventilation space.
May be configured to communicate with the opening 9 b on the inlet side of the suction pipe 9.

Accordingly, the lint collecting chamber 8 and the lint collecting chamber 24 are partitioned by the lint collecting chamber ceiling 7 and the lint filter 6, and the lint collecting chamber 24 and the side ventilation space 28 are separated from each other. ,
The fly waste collection chamber 24 and the upper ventilation space 33 are partitioned by the walls 25 to 27 and the side filter 30.
And the upper surface filter 31. The lint collection chamber 8 and the side ventilation space 28 are partitioned by the lint collection filter 6.

Here, the behavior of the flow of fly waste and the flow of suction air in the dust box 2 will be described with reference to FIGS. 4 and 5. FIG. However, in FIGS. 4 and 5, for convenience of explanation, the bypass duct 18, the opening 18a, the switching device 20, and the flapper 23 are omitted.

When the impeller 10 of the blower box 11 rotates, a suction air flow passing through the lint filter 6, the front filter 29, the side filter 30, and the top filter 31 is generated in the dust box 2. In this state, The fly waste is carried by the fly waste duct 3 from each of the spinning units 1 shown in FIGS. 2 and 3 on the above-mentioned suction air flow, exits the opening 3a, and is sent into the fly waste collecting chamber 24.

In FIG. 4, the inner peripheral surface 9a of the suction pipe 9 is opposed to the intersection 32 of the fly waste collecting chamber 24 at the position P (intersection 32).
(Where the line or surface extending in the axial direction of the suction pipe 9 intersects the side wall 2d).

In this case, by combining the forward component 39 and the lateral component 40 of the air flow, the fly fly draws a trajectory as shown in FIG. It adheres and accumulates at the intersection 32.

On the other hand, in FIG. 5, the inner peripheral surface 9a of the suction pipe 9 is shown.
Is located outside the position facing the intersection 32 of the fly waste collection chamber 24.

In this case, due to the synthesis of the forward component 39 and the lateral component 40 of the air flow, the fly fly draws a trajectory that gradually flows in the direction of the side filter 30, that is, in the lateral direction, as shown in FIG. The air flow component 41 shown in FIG. 2 causes the filter to adhere and accumulate at a position slightly away from the intersection 32 of the three filters.

The reason why the position where the fly waste adheres and accumulates as described above is considered to be due to the following factors.

In the case of the fiber waste collecting apparatus 34 shown in FIG. 4, since the inner peripheral surface 9a of the suction pipe 9 is located inside the position P facing the intersection 32 of the fly waste collecting chamber 24,
That is, since the inner peripheral surface 9 a of the suction pipe 9 is located inside the side filter 30, the suction air flow passes through the lint filter 6 and flows to the side suction space 28 in the forward direction. (Direction of arrow 38) and a forward component flowing from the fly waste duct 3 to the fly waste collection chamber 24 and the front filter 29, or an upward component flowing through the upper filter 31 to the upper suction space 33 (arrow) 41 direction), the pressure loss due to bending is large, so that the side ventilation space 2
8 suction air flow in the forward direction (direction of arrow 38)
Is a forward suction air flow 39 flowing through the fly waste collection chamber 24.
And the suction power for sucking fly waste is weak.

As a result, of the air flow in the direction of the obliquely forward arrow 40 flowing from the fly waste collection chamber 24 through the side filter 30 and into the side ventilation space 28, the horizontal component (the side filter 30 (A component orthogonal to). In the state of the air flow as described above, the fly waste sent to the fly waste collection chamber 24 is subjected to the air flow in the direction of the arrow 40 in the region surrounded by the front filter 29, the side filter 30, and the top filter 31. While moving in the horizontal direction by the horizontal component, the intersection portion 32 is formed by combining with the airflow component in the forward direction of the arrow 39.
Will go to Further, since the same can be said between the upward component flowing in the upper suction space 33 after passing through the upper surface filter 31 (in the direction of arrow 41) and the airflow component obliquely forward in the direction of arrow 40, the intersection can be obtained. Attach to 32 and accumulate.

On the other hand, in the case of the fiber waste collecting apparatus 34 shown in FIG. 5, the inner peripheral surface 9a of the suction pipe 9 is located outside the position P facing the intersection 32 of the fly waste collecting chamber 24. Accordingly, the forward component (direction of arrow 38) of the suction air flow that passes through the lint filter 6 and flows through the side ventilation space 28 has a small pressure loss due to bending. It is greater than the forward airflow flowing in the direction.
Therefore, the horizontal component of the oblique horizontal air flow 40 that flows from the fly waste collection chamber 24 into the side ventilation space 28 through the side filter 30 is reduced.

In the state of the air flow as described above, the fly waste sent into the fly waste collection chamber 24 is directed in the direction of the arrow 40 in a region surrounded by the front filter 29, the side filter 30, and the top filter 31. Since the horizontal component of the air flow is small, the lateral movement is smaller than that in FIG.
5 from the intersection 32 to a position slightly lower in the plane of FIG. Further, since the same can be said between the upward component flowing in the upper suction space 33 after passing through the upper surface filter 31 (in the direction of arrow 41) and the airflow component obliquely forward in the direction of arrow 40, the intersection can be obtained. From 32, the toner is slightly deposited at a lower position in FIG.

Here, the change in the negative pressure in the dust box 2 when the dust box 2 shown in FIG. 1 (referred to as the present invention in FIG. 6) is used and the dust box described in "Problems to be Solved by the Invention". FIG. 6 shows a bar graph showing the result of comparison with a change in negative pressure in the box when a conventional device is used. The horizontal axis in the bar graph of FIG. 6 indicates the volume amount (unit: kg) of fluff in each dust box, and the vertical axis indicates the measured negative pressure (unit: mmAq) in each dust box.

In FIG. 6, when the amount of fly waste is 0 (kg), it is 400 (mmAq) in the conventional machine, but about 350 (mmAq) in the machine of the present invention (dust box 2).
This indicates that the conventional machine has a larger negative pressure value and a stronger suction air flow than the machine of the present invention, but when fluff is accumulated and becomes 2 (kg), the conventional machine becomes Indicates that the negative pressure value sharply decreases and is substantially equal to that of the present invention. Further, when the amount of accumulated fly waste increases to 4 (kg), the negative pressure value of the present invention machine is clearly larger than the negative pressure value of the conventional machine, and the accumulated fly waste amount is 6 (kg). At 8 (kg), this magnitude relationship continues.

That is, FIG. 6 shows that the degree of decrease in the negative pressure value in the machine of the present invention is slower than that in the conventional machine. This is shown in FIG.
As shown in FIG. 2, a front filter 29 that is substantially perpendicular to the axial direction of the suction pipe 9 and a side filter 30 that is substantially perpendicular to the front filter 29 to form the fly waste collection chamber 24. And the upper surface filter 3 which is substantially orthogonal to the side filter 30 together with the front filter 29
1 and a side ventilation space 28 communicating with the suction pipe 9 is provided outside the collection chamber 24 of the side filter 30, so that the three filters 29, 30, and 31 intersect with each other at a substantially right angle.
2 In other words, fiber waste (fly waste) is easily deposited at the corners of the fly waste collection chamber 24, and it is possible to prevent uniform deposition on the surfaces of the filters 29, 30, and 31. It can be said that even if the amount of fly waste increased by such a configuration, the result that the time when the deposited fly waste affects the suction air flow can be delayed was obtained. Therefore, the total area of the filters increases, and the three filters 29, 30, 3
By intensively depositing the fiber debris on the first bent portion, the suction air flow can be maintained, and the period of the cleaning operation of the fly and the like performed by the operator can be lengthened.

Further, the inner peripheral surface 9a of the suction pipe 9 is positioned on the front side more than the position P which faces the orthogonal portion between the front filter 29 and the side filter 30, that is, the intersection P where the three filters 29, 30, 31 intersect. Arrow 3 that flows straight through side ventilation space 28 by being located inside filter 29
By suppressing the components of the suction air flow in eight directions, the components of the suction air flow in the direction of arrow 40 from the fly waste collection chamber 24 to the side ventilation space 28 are increased, and the fly waste is more easily deposited on the intersection 32. Can be guided.

Further, since the lint filter 6 and the suction pipe 9 are communicated with each other via the side ventilation space 28, the amount of fly waste accumulated in the fly waste collecting chamber 24 increases, and the accumulated fly waste Are front filter 29, side filter 30, top filter 31
Even if the air flow passage portion is blocked, the suction air flow 38 can suppress a decrease in the suction force in the slack tube duct 4, the lint collection duct 5, and the lint collection chamber 6.

[0039]

Fiber waste (fly wool) easily accumulates in the portion, thereby preventing uniform accumulation on the filter surface. Therefore, the suction air flow is maintained by intensively depositing the fiber waste on the bent portion, and the period of the cleaning operation of the fly and the like performed by the operator can be lengthened.
