Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a method for removing sewing waste in a sewing factory,
In a sewing factory that uses a large number of industrial sewing machines to cut and sew various types of women's clothing, children's clothing, etc., the central dust collection equipment that cleans the fabric is used to cut and sew fabric. This system automatically collects and disposes of sewing waste (female waste) generated by cutting when sewing while aligning edges and cutting, keeping the inside of a garment factory that has cutting areas, sewing areas, finishing areas, etc. clean. The present invention relates to a sewing waste concentrated dust collection device in a sewing factory, which improves the working environment.

(Prior art) In general, various types of clothing including women's clothing are
After the original fabric is cut by a cutting machine in a cutting factory, it is sewn in large quantities by a high-speed sewing machine for the sewing industry in a sewing factory.

For garment factories equipped with such cutting machines and high-speed sewing machines, it is particularly important to consider how to efficiently allocate a large number of sewing machines and the workers who operate them, and how to operate and work without wasting time. Costs vary greatly depending on the Therefore, how the sewing machines are arranged and how the work performed by the workers is managed are very important factors in whether or not the sewing machine can be provided at a low cost.

However, in the cutting process using a cutting machine, the edges of the fabric are cut together, and in the sewing process using an industrial sewing machine, the edges of the fabric are aligned and cut while sewing. During the process and sewing process, a large amount of sewing waste is generated.
In particular, if sewing waste is left unattended in a sewing shop, it will scatter around sewing machines and workers, and become a major cause of hindering improvements in work efficiency. Therefore, we stop work at predetermined intervals and collect sewing waste.
It is being removed.

However, such work interruptions are not desirable in terms of sewing process control, since they increase work losses and contribute to increased costs.

Therefore, as shown in FIG.
A vacuum device 103 having a suction port 102 is disposed near the sewing/cutting section to collect and remove sewing waste by vacuum suction.

This vacuum device 103 includes a forced air blower 104 driven by a motor, a dust collection tank 105 that collects and stores sewing waste, and a suction pipe 106 that has the suction port 102 at its tip and is located at a place where sewing waste is generated. A blower pipe 107 is connected to the suction pipe 106 and makes the inside of the suction pipe 106 a negative pressure by the inflow of air from the blower 104, and a check valve is provided near the outlet of the suction pipe 106. 108. That is, the blower 104 driven by a motor
By the suction action accompanying the air blowing, sewing waste generated in the sewing/cutting section of the sewing machine is sucked and collected in the dust collecting tank 105.

(Problem to be solved by the invention) However, these conventional vacuum devices 10
According to No. 3, since the check valve 108 is opened and closed by the suction action generated in the blower pipe 107, the sewing waste may clog the check valve 108 at the position where the sewing waste flows. Then, blower 1
04 may not be suctioned at the suction port 102 and may flow back through the suction pipe 106 and blow out as it is, or sewing waste stored in the dust collection tank 105 may flow back and cause the air to flow back through the suction port 102.
There were times when I would burst out laughing. Further, as a result of this blowout, machine oil and the like adhering to the sewing waste sometimes adhered to the fabric being sewn and soiled it.

Further, even if such a sewing waste collection system can automatically collect sewing waste near the sewing/cutting section of the sewing machine 101, fine sewing waste that cannot be collected by the suction port 102 may be collected automatically. floating in the garment factory, resulting in a poor working environment throughout the garment factory.

Furthermore, as stated in Utility Model Publication No. 52-10526,
When suctioning and collecting thread waste, cotton dust, etc. using a suction pipe placed near the sewing machine needle, a silencer is connected to the exhaust side of the suction drive source, and this silencer removes suspended substances in the exhaust gas with water. A sewing waste collection device has been proposed in which the sewing waste is moistened by water and collected by settling through a filter in a water tank. However, according to this, even if floating dust in the exhaust air from the silencer could be removed and recovered, there was insufficient ventilation within the factory, which had a major impact on the working environment throughout the factory. Therefore, separate air purification and purification equipment had to be installed in order to remove and collect the dust floating in the sewing machine workshop or the entire sewing shop.

Therefore, in view of the existing circumstances as described above, the present invention was created in order to eliminate these various drawbacks.The present invention was created in order to eliminate these various drawbacks. Fine sewing waste generated in sewing factories,
The purpose of the present invention is to provide a centralized dust collection device for sewing waste in a sewing factory that can automatically remove cutting waste and other items from inside the sewing factory, improve the working environment, increase the efficiency of cleaning work, and significantly reduce costs. shall be.

(Means for Solving the Problems) In order to solve the above-mentioned problems, one of the sewing waste concentrated dust collection devices in a garment factory according to the present invention is designed to solve the problems described above. A suction pipe with a suction port located near the sewing/cutting section allows you to switch and select whether to suck air from around the sewing machine through the suction port or to suck air from other locations within the sewing factory. The switching means for carrying out the operation is connected to a dust collection tank that collects and stores sewing waste,
The present invention is characterized by comprising a conveyance duct connected to the switching means and a suction mechanism that constantly sucks the inside of the conveyance duct.

Furthermore, in the case of another one, there is a suction pipe having a suction port located near the sewing/cutting section of the sewing machine that is appropriately laid out in the sewing factory, and a suction pipe that communicates with this suction pipe to collect sewing waste. A damper mechanism has a damper mechanism that has a charging chamber directly below the storage tank for temporarily storing sewing materials, via a damper that swings open and close in the vertical direction, and a damper mechanism that stores sewing waste generated at the sewing/cutting section in the storage tank. a suction mechanism for sucking sewing waste into the dust collection tank; a conveyance duct that communicates with a dust collection tank that collects and stores sewing waste and is continuous with the input chamber; and a suction mechanism that sucks sewing waste in the conveyance duct into the dust collection tank. It is characterized by:

(Function) In the sewing waste concentrated dust collector in a sewing factory according to the present invention, when each sewing machine operator starts sewing work using sewing machines that are appropriately laid out in the sewing factory, the sewing/cutting section of the sewing machine Sewing waste to be cut and removed is sucked by a vacuum suction operation at a suction port located nearby.

At this time, according to the suction mechanism in the dust collection section that is constantly in operation, the air from the sewing machine is either sucked through the suction port or from other places in the sewing factory when the switching means is switched. Do not suck the air in place. If air is being sucked in next to the sewing machine, the sewing waste generated therein is sucked in and transported into the dust collection tank via the transport duct. Furthermore, if air is being sucked from other locations within the sewing factory, the air within the factory will also be circulated, and fine sewing waste throughout the entire factory will also be suctioned and removed.

By constantly suctioning, the load on the suction mechanism is always constant, allowing stable operation in the dust collection section.

Further, by temporarily collecting and holding sewing waste in the accumulation storage tank of the damper mechanism, an appropriate amount of sewing waste is accumulated in the damper mechanism as the sewing waste is accumulated and held. Then, when the bottom of the storage tank is opened by the rocking motion of the damper in the damper mechanism, the accumulated sewing waste is dropped by suction into the input chamber directly below the storage tank.

The charging chamber is communicated with the conveyance duct and the dust collection tank, and therefore, sewing waste is collected into the dust collection tank via the conveyance duct by suction operation from the dust collection tank by the suction mechanism.

In any case, the sewing waste stored and stored in the dust collection tank in this way is then, for example,
It is disposed of appropriately, such as by using it as heating fuel.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 to 8.

That is, in the present invention, various sewing wastes generated in the sewing factory F are sucked together with the air in the factory through the conveyance ducts 11, 12, 13, and 51 piped into the sewing factory F, and the suctioned sewing scraps are Dust collection tank 2 separated from air and installed at a designated location
The aim is to centrally store it within 1,50 yen.

Therefore, when constructing the sewing waste concentrated dust collection device according to the present invention, the first embodiment concentrates the sewing waste in the dust collection tank 21 by a constant suction method, and the first embodiment collects the sewing waste in the damper mechanism 40 and then , and a second embodiment in which the dust is concentrated in the dust collection tank 50 by suction operation again.

[First Embodiment] In the first embodiment shown in FIGS. 1 to 5, reference numeral 1 in the figures is a sewing machine,
A suction port 2 is located near the sewing/cutting section of the sewing machine 1 to vacuum up sewing waste generated during sewing and cutting.
It is equipped with The sewing machines 1 themselves are arranged, for example, in a plurality of opposing rows according to the layout in the sewing factory F, so that the configuration of the later-described conveyance ducts 11, 12, 13 and other piping can be simplified.

The piping configuration is such that the overall layout of the sewing factory F is, for example, as shown in FIG.
An example of a case where the sewing shop M and the finishing shop N are arranged adjacent to each other in order and the sewing waste dust collecting section 20 is arranged outside the factory building is as follows. That is, the centralized conveyance duct 11 is connected to the dust collection tank 21 in the dust collection section 20 located outdoors of the cutting shop C.
A main conveyance duct 12 extending along the center of the sewing factory M is connected to the end of the concentrated conveyance duct 11 at the cutting factory C, and on the left and right of this main conveyance duct 12, Branch conveyance ducts 13 located in front of and between the sewing machines 1 arranged in a plurality of opposing rows are connected in a branched manner, and these conveyance ducts 11, 12, 13 in the sewing factory F are connected to each other in a branched manner. The pipes are installed under the floor (see Figure 2).

Further, as shown in FIG. 2, the branch conveyance duct 13 is located below a storage channel 4 having a groove-shaped cross section, which is disposed on the floor of the factory between the sewing machines 1 arranged in an opposed manner in front of each other. The opening surface of the storage channel 4 substantially matches the floor surface. By doing this, the switching operation by the switching means 5, which will be described later, arranged in the storage channel 4,
and facilitate its maintenance and inspection work.

Sewing waste generated near the sewing/cutting section of the sewing machine 1 is sucked by a suction port 2, and sucked into the delivery ducts 11, 12, 13 by a suction pipe 3 connected to the suction port 2. and transported to the dust collecting section 20.

Inside the conveyance ducts 11, 12, 13, there is a dust collection section 2.
0, the suction mechanism 22 consisting of a motor and a blower is in a constant state of suction, and by operating the switching means 5, the air next to the sewing machine 1 can be suctioned through the suction port 2, or the air inside the sewing factory F can be suctioned. It is now possible to switch and select whether to suck air from other locations.

As shown in FIGS. 2 to 4, this switching means 5 is provided within the storage channel 4, and is located, for example, between the front and between the sewing machines 1 facing each other. The switching means 5 itself has a closing cap 6 or the suction pipe 3 attached to the upper end of the suction pipe 14 which is branched from the branch conveyance duct 13 and raised up into the storage channel 4. A removably connected connection cap 7 is attached in a replaceable manner, and an on-off valve 9 is provided on a suction pipe 15 which is branched from a suction pipe 14 and whose open end is located below the floor surface of the factory. It is.

The closing cap 6 is formed in a blind shape so as to close the upper end of the suction pipe 14, as shown in FIG. An appropriate number of connecting pipes 8 having a diameter corresponding to the suction pipe 3 can be freely connected.
The connecting tubes 8 shown in the drawing are of two sizes, one large and one small, and are provided in a pair to correspond to the suction ports 2 of the respective sewing machines 1 facing each other.

The open end of the suction pipe 15 is designed to suck air from below the floor of the factory.
As shown in the figure, the projecting direction is not limited to the case of projecting downward in the storage channel 4, but the projecting direction may be changed to the side of the storage channel 4.

Now, if you want to make the sewing machine 1 suction sewing waste, as shown in FIG. By closing the opening/closing valve 9, the suction pipe 15 is closed.
Then, the suction mechanism 2, which is constantly operating in the suction state,
Sewing waste generated in the sewing/cutting section of the sewing machine 1 by the suction pipe 3 is sucked by the suction pipe 3, and is sucked into the dust collection section 20 through the ducts 13, 12, and 11.

When the sewing machine 1 stops sewing and no sewing waste is generated, the upper end of the suction tube 14 is closed with the closing cap 6, and the on-off valve 9 is opened, as shown in FIG. 4B. Depending on the operation, the suction pipe 15
Leave the gauze open. Then, the suction mechanism 22 in the constant suction state will suck air from below the factory floor, and this will circulate the air in the garment factory F in general, so that the air in the factory will be It helps a lot in cleaning. Not only that, but by suctioning air from under the floor, fine sewing debris floating in the factory is drawn to the floor, making the working environment in the factory extremely good.

Note that the switching operation by this switching means 5 is as follows:
It is not limited to the case where only one of them is used completely, but it may be set so that both of them are sucked at the same time, so that each has half the capacity. In addition, the switching means 5 is not limited to being placed in the storage channel 4, but may be placed at almost the same height as the suction port 2 of the sewing machine 1. By doing so, the switching operation can be simplified. It's easy to do.

The sewing waste thus sucked through the branch conveyance duct 13, the main conveyance duct 12, and the concentrated conveyance duct 11 is stored and stored in the dust collection tank 21 in the dust collection section 20.

As shown in Fig. 1, the dust collecting section 20 is placed outside the building of the garment factory F, and separates only the sewing waste sucked in together with the air inside the garment factory F, and the air is released into the atmosphere. It is structured as follows.

That is, as shown in FIG. 5, a cyclone separator 23 with the end of the concentrated conveyance duct 11 connected to the upper part of the outer wall is provided on the dust collection tank 21, and the cyclone separator 23 is installed in the center of the upper wall of the cyclone separator 23. An intake pipe 24 is connected to the inner wall of the engine, a suction mechanism 22 is connected to the intake pipe 24, and an exhaust pipe 25 is connected from the suction mechanism 22.

The illustrated cyclone separator 23 is formed into an inverted conical shape that gradually becomes smaller in diameter as it goes downwards, and is arranged in parallel in two groups on the left and right, and is branched from the end of the centralized conveyance duct 11 to be used in the factory. Air and sewing waste are brought in. Then, due to the inertial action and gravity action within the cyclone separator 23, the sewing waste is removed from the cyclone separator 23.
The dust collection tank 21 is located below along the inner surface of the outer peripheral wall.
The air also falls into the cyclone separator 23
The intake pipe 24
It's starting to get sucked in.

The dust collection tank 21 has a substantially box-like structure, and a door provided at the front allows the trolley 26 loaded inside to be taken out. dust tank 21
It is made so that it can be taken outside.

Further, a duct chamber 27 having an appropriate number of nets arranged therein is interposed at a portion of the suction pipe 24 immediately in front of the blower in the suction mechanism 22 to protect the blower.

In addition, the reference numeral 16 in the figure is a cleaning opening for facilitating cleaning inside the garment factory F, and 17
1 is an inspection port that can be opened and closed to inspect the conditions under the factory floor, and 18 is an air purifier attached to the ceiling to remove fine sewing waste floating in the factory.

This first embodiment is constructed as described above, and next, an example of its use will be explained.

When each sewing machine operator starts sewing work using the sewing machine 1 which is appropriately laid out in the sewing factory F, the suction port 2 located near the sewing/cutting section of the sewing machine 1 is used to generate water through the suction pipe 3. The sewing waste to be cut and removed is suctioned by a vacuum suction operation.

That is, the suction mechanism 22 in the dust collecting section 20
Since the is constantly in suction operation, when the switching operation is performed by the switching means 5, the air around the sewing machine 1 is sucked through the suction port 2, or it is sucked out from other places in the sewing factory F, e.g. Suction the air under the floor.

If the air is being sucked next to the sewing machine 1, the sewing waste generated there is sucked and the branch conveyance duct 1 is
3. The dust is transported into the dust collection tank 21 via the main transport duct 12 and the central transport duct 11.

Further, when the air under the floor in the sewing factory F is sucked, the air in the factory is also circulated, and fine sewing waste throughout the factory is also suctioned and removed.

And, by constantly suctioning, the suction mechanism 2
The load at 2 is always constant, enabling stable operation.

According to the first embodiment configured as above,
The suction mechanism 22 in the dust collection section 20 constantly sucks the air inside the sewing factory F along with sewing waste, so when the suction mechanism 22 is operated, there is no possibility of instability such as the load increasing or decreasing. Without a problem,
It is always constant, and there is no need to make it excessive in terms of capacity.

In addition, by switching operation by the switching means 5, the air under the floor is sucked outside the sewing work, and the air is made to flow from the upper part to the lower part in the sewing factory F. Since it is constantly circulated, the inside of the factory can be kept in an extremely clean condition. In addition, in practice, approximately 1
It has been confirmed that it is possible to exchange the air in the factory in about an hour.

[Second Embodiment] In the second embodiment shown in FIGS. 6 to 8, reference numerals 1 and 2 in the figures are a sewing machine and a suction port, as in the first embodiment, and the sewing machine 1 itself is are arranged, for example, in a plurality of facing rows according to the layout in the garment factory, and are connected to the conveyor ducts 5 described later.
1. Simplify the configuration of other piping (see Figure 7).

The sewing waste sucked by the suction port 2 is collected in the damper mechanism 40 through the suction pipe 3 connected to the suction port 2, as shown in FIG. As shown in FIG. 7, the suction port 2 and the suction pipe 3 are attached to each sewing machine 1, and the suction mechanism 35 consisting of a blower, motor, etc. for vacuum suction is provided in two units as shown in the figure. It is not limited to the case where it is provided for each pair of sewing machines 1, or even for each sewing machine 1, but it may be provided in a unit type so that several sewing machines 1 are grouped together and subjected to vacuum suction. In the former case, the drive can be controlled depending on the work situation and work status of each worker, and individual circumstances can be dealt with, whereas in the latter case, batch processing is possible. Which one to adopt is arbitrary, and the choice is made so that the driving cost is low.

The damper mechanism 40 is used to collect and temporarily store sewing waste generated in each sewing machine 1 in a dust collection tank 50 (to be described later).
1 and the suction pipe 3 are communicated with each other so that they can be opened and closed freely. That is, as shown in FIG. 8, an accumulation storage tank 41 is connected to the suction pipe 3 and temporarily stores the vacuum-suctioned sewing waste.
At the top, there is a loading chamber 46 communicating with the conveying duct 51.
A damper 47 that swings in the vertical direction is provided at the lower part thereof, and a damper 47 that swings in the vertical direction is provided at approximately the center so that the integrated storage tank 41 and the input chamber 46 are communicated with each other in an openable and closable manner.

The accumulation storage tank 41 is formed into a substantially trapezoidal box shape with a cross section that gradually becomes narrower as it reaches the bottom, and a connecting pipe 43 connected to the suction pipe 3 is connected to a lid plate 42 that closes the upper opening. A connecting pipe 44 connected to the blower of the suction mechanism 35 is provided on any arbitrary side wall, and a net 45 is stretched over the opening of the connecting pipe 44 inside the side wall of the accumulation storage tank 41. Therefore, when vacuum suction is started by the operation of the suction mechanism 35, as the inside of the accumulation storage tank 41 becomes vacuum, sewing waste is suctioned from the suction port 2 through the suction pipe 3, and the sewing waste is sucked out. The collected sewing waste remains in the accumulation storage tank 41 by a net 45 and is accumulated therein.

The charging chamber 46 is located directly below the accumulation storage tank 41 , and the bottom portion opened below the charging chamber 46 communicates with the transport duct 51 .
By opening the bottom of the accumulation storage tank 41 by the opening operation, the sewing waste is sucked and dropped into the conveyance duct 51.

The damper 47 is controlled to swing by, for example, a motor (not shown) disposed outside the input chamber 46, and swings downward at fixed intervals and at fixed accumulation amounts of sewing waste. The movement is released. That is, the damper 47 is pivotally connected to the tip of a damper arm 48 fixed to the motor drive shaft on the back side thereof, and is press-fitted to a gasket 49 fixed around the bottom opening of the accumulation storage tank 41. 41 is hermetically closed to improve the suction efficiency of the vacuum suction action by the suction mechanism 35.

On the other hand, the conveyance duct 51 is connected to the dust collection tank 50, and a suction mechanism 5 that vacuums the inside of the dust collection tank 50 removes sewing waste that has fallen into the conveyance duct 51.
The dust is conveyed and suctioned into the dust collection tank 50 by the vacuum driving action of the dust collection tank 50.

The dust collection tank 50 itself is installed at an appropriate location outside the building of the sewing factory F, in which, for example, the sewing machines 1 are arranged, and has an outlet for taking out the sewing waste accumulated and stored inside. The operation of the suction mechanism 55 for transporting sewing waste into the dust collection tank 50 is as follows:
It does not need to be carried out all the time, and it is sufficient if it is driven at least after the damper 47 is opened, and its suction capacity is limited to the charging chamber 46 of all the damper mechanisms 40.
There is no need to suck up all the sewing waste at once.

In addition, a suction mechanism 55 that causes the dust collection tank 50 to perform suction, and the suction mechanism 35 that causes sewing waste from the sewing/cutting section to be sucked into the accumulation storage tank 41.
It is also possible for one suction mechanism unit to serve both functions by operating them separately by switching the flow paths.

This second embodiment is constructed as described above, and next, an example of its use will be explained.

Sewing machines 1 randomly laid out in a sewing factory
When each sewing machine operator starts sewing work, the suction mechanism 35 operates to suction the sewing waste at the suction port 2 located near the sewing/cutting section of the sewing machine 1, and the sewing waste is transferred to the damper mechanism 40. Temporarily accumulated and held in an accumulation storage tank 41.

After this accumulation is maintained and when a suitable amount has been accumulated, the bottom of the accumulation storage tank 41 is opened by the downward swinging motion of the damper 47 in the damper mechanism 40,
The accumulated sewing waste is dropped into the input chamber 46 by suction. After opening and falling, it swings upward again and closes, sealing the bottom of the accumulation storage tank 41 and waiting for the next operation.

Since the input chamber 46 is communicated with the conveyance duct 51, sewing waste is collected into the dust collecting tank 50 via the conveyance duct 51 by suction operation of the suction mechanism 55.

According to the second embodiment configured as above,
Sewing waste generated under each sewing machine operator is removed from the suction port 2.
Accumulation storage tank 4 with damper mechanism 40
Once accumulated and held in the dust collection tank 50 , the dust can be collected in the dust collecting tank 50 by the opening operation of the damper 47 and the suction operation of the suction mechanism 55 .

Moreover, the suction operation in the suction pipe 3 and the dust collection tank 20 allows the air flow obtained by the vacuum suction operation of the suction mechanisms 35 and 55 to be used for air conditioning by the air conditioner in the garment factory F. This allows effective use of airflow.

[Effects of the Invention] Therefore, according to the present invention configured as described above, sewing waste generated under each sewing machine operator is
Since the cleaning process is done automatically and does not bother the sewing machine operator, sewing work can be done extremely efficiently, leading to significant cost reductions, and moreover, airflow can be reused effectively. It has excellent effects such as being useful for air conditioning.

In particular, by switching the switching means in the suction mechanism of the dust collecting section, the air around the sewing machine is suctioned through the suction port, making it possible to suction sewing waste generated by the sewing machine. The air inside the factory is circulated by suctioning air from other places within the factory, and it is also possible to suction and remove fine sewing waste, floating dust, etc. throughout the factory, purifying the air throughout the factory. A good working environment can be maintained.

Even if the suction point is switched using the switching means in the suction mechanism, the suction mechanism of the dust collection section can be operated at all times, so the load on the suction mechanism is always constant, and the load on the dust collection section does not change. This has the advantage of reducing friction, enabling stable operation, and reducing failures.

Furthermore, the sewing waste is temporarily accumulated and retained in the accumulation storage tank of the damper mechanism, and is sucked from the accumulation storage tank with the bottom open into the input chamber directly below this accumulation storage tank by the rocking motion of the damper of the damper mechanism. Because it is made so that it can fall by
This improves the suction efficiency of the vacuum suction action by the suction mechanism, and is useful for downsizing the device.

Furthermore, since the charging chamber is communicated with the conveyance duct and the dust collection tank, the sewing waste is collected into the dust collection tank via the conveyance duct by the suction operation of the suction mechanism from the dust collection tank. The collected sewing waste can be appropriately reused, for example, as fuel for heating, and there is no waste.
