The roll cartridge 21 is slidably engaged with a slide body 24 on a rail 23 supported substantially horizontally, and a plurality of roll cartridges 21 are fixed on the upper surface of the slide body 24 so as to be aligned in the slide direction. Accordingly, two roll cartridges 21 are arranged side by side so that the inner material 10 is drawn downward from the roll cartridge 21 on the left side in FIG.
[0015]
Further, a sensor for detecting the inner material 10 drawn from the roll cartridge 21 is provided between a drawer port 21a1 of the roll cartridge 21 used first (the left roll cartridge 21 in FIG. 2) and a driving roller 22a described later. 44 is disposed.
The sensor 44 is used to determine that the inner material roll 10 ′ in the upper roll cartridge 21 has been used up when the inner material 10 is no longer detected. The inner material roll 10 ′ is exchanged for another existing one.
[0016]
The feeding roller mechanism 22 sandwiches the inner material 10 between a driving roller 22a rotated by a driving source (not shown) and the driving roller 22a below the roll cartridge 21 on one axial end side (left side in FIG. 2). And the driven roller 22b that is rotated at the same position, and the inner material 10 drawn out from the roll cartridge 21 is fed downward.
[0017]
According to the inner material supply unit 20 configured as described above, the inner material 10 in the roll cartridge 21 on the one end side (left side in FIG. 2) is fed out in the longitudinal direction of the inner material 10 by the feeding roller mechanism 22, and The feeding tip side is suspended and supplied downward.
When the inner material roll 10 ′ in the one end side roll cartridge 21 is used up, the plurality of roll cartridges 21 are simultaneously slid in the substantially horizontal direction, and the used roll cartridge 21 (on the left side in FIG. 2) is used. Is replaced with the roll cartridge 21 before use (on the right side in FIG. 2).
[0018]
The fusion cutting mechanism 30 is disposed in the middle of the supply path of the inner material 10. Specifically, the fusion cutting blade 31 and a movable blade receiving type that contacts the fusion cutting blade 31 so as to sandwich the inner material 10. 32.
[0019]
The fusion cutting blade 31 is a mold having a curved shape in a plan view protruding toward the inner material 10 side, and is heated within a temperature range of about 380 to 450 degrees by the heater portion 31a on the back side. In addition, a sensor 45 for detecting the fed inner material 10 is disposed below the fusion cutting blade 31. This sensor 45 detects that the inner material 10 has been cut and dropped by the fusion cutting blade 31, and immediately after that, the movable blade receiving die 32 is controlled to move away from the fusion cutting blade 31. Is for.
[0020]
The movable blade receiving die 32 is a plate material made of fluororesin such as tetrafluoroethylene resin, and is configured to abut on the fusion cutting blade 31 by advancing and retreating by a horizontal drive mechanism 34 such as a cylinder piston mechanism. Yes. According to the illustrated example, the movable blade receiving die 32 has a substantially inverted U-shaped cutout portion 32a. The cutout portion 32a prevents the movable blade receiving die 32 from being warped by thermal deformation. It is for releasing distortion. In addition, the material of the movable blade receiving die 32 is not limited to the above-described material. For example, a metal material or a metal material coated with a fluororesin may be used. It is preferable that the material is difficult to adhere.
[0021]
According to the above configuration, when the movable blade receiving die 32 comes into contact with the fusion cutting blade 31, the cylindrical inner material 10 is fused in a closed shape by the heat of the fusion cutting blade 31, and the fusion The cutting is performed along the fusion cutting blade 31 substantially simultaneously with the arrival.
When the cut inner material 10 (inner 11) falls due to its own weight, the sensor 45 detects the fall, and the movable blade receiving die 32 is controlled to move away from the fusion cutting blade 31.
[0022]
Further, according to a preferred example of the present embodiment, the ejection nozzle 46 that assists the falling of the cut inner material 10 (inner 11) due to its own weight by air pressure, and the payment for surely removing the inner material 10. A drop bar 33 is provided.
[0023]
The ejection nozzle 46 is disposed so as to eject air from the upper side of the fusion cutting mechanism 30 toward the space between the fusion cutting blade 31 and the movable blade receiving die 32, and the inner 11 The fusion cutting part is cooled and solidified, and the inner 11 is blown downward.
According to the ejection nozzle 46, the fusion cut portion of the inner 11 is rapidly solidified after the fusion, so that it is less likely to be stretched into a yarn shape by heat. Further, even if the fusion cutting portion of the inner 11 is stretched into a thread shape by heat, and the upper end portion of the thread portion adheres to the fusion cutting blade 31, the movable blade receiving die 32, the upper inner material 10 or the like. The inner 11 hung by the thread-like portion can be blown off from above and dropped downward.
[0024]
The scraping bar 33 is a rod-shaped member 33 a formed at least longer than the horizontal width of the fusion cutting blade 31, and the turn-off drive source 33 b supported integrally with the movable blade receiving die 32. By being fixed to the moving shaft, the tip end side is configured to rotate up and down.
As for this dropping bar 33, the fusion cutting part of the inner 11 cut | disconnected by the said fusion cutting mechanism 30 is the fusion cutting blade 31 of the fusion cutting mechanism 30 with the heat | fever, the movable blade receiving die 32, the upper side. Adhering to the inner material 10 or the like, or the fusion cutting portion is stretched into a thread shape by heat, and the upper end portion of the thread portion is the fusion cutting blade 31 of the fusion cutting mechanism 30, the movable blade receiving die 32, When it adheres to the inner material 10 or the like on the side, the inner 11 or the thread-like portion is struck down from above to be surely dropped.
[0025]
The cutting mechanism 40 is disposed in the middle of the supply path of the inner material 10 on the lower side of the fusion cutting mechanism 30. Specifically, the cutting blade 41 and the cutting blade 41 are arranged so as to sandwich the inner material 10 therebetween. A receiving plate 42 for abutting the tip is provided, and the inner material 10 is sandwiched between the cutting blade 41 and the receiving plate 42 and cut in a substantially horizontal shape.
[0026]
The cutting mechanism 40 is configured integrally with a cutting blade 41 and a receiving plate 42, and the cutting blade 41 is brought into contact with and separated from the receiving plate 42 by a horizontal drive mechanism (not shown) including a cylinder piston mechanism or the like. The receiving plate 42 integrated with the cutting blade 41 is supported by a vertical drive mechanism (not shown) such as a ball screw mechanism so as to be movable in the vertical direction.
Therefore, the cutting mechanism 40 cuts the inner material 10 between the cutting blade 41 and the receiving plate 42 and makes the cutting position adjustable by the vertical movement of the cutting blade 41 and the receiving plate 42.
According to a preferred example of the present embodiment, the length of the inner 11 can be adjusted within the range of 45 to 90 cm by adjusting the cutting position of the cutting mechanism 40 in the vertical direction.
[0027]
Further, a position sensor 43 is disposed below the cutting blade 41.
The position sensor 43 detects the lower end portion 10a of the inner material 10 that is suspended and fed downward, and controls the cutting blade 41 in the cutting direction substantially simultaneously with the detection of the lower end portion 10a.
Therefore, the length of the lower end side portion of the inner material 10 relative to the cutting blade 41, that is, the length of the hamper portion 12 (see FIG. 4A) is determined by the position of the position sensor 43 in the vertical direction. . The position sensor 43 may be attached so as to be movable in the vertical direction so that the length of the hamper portion 12 can be varied as required.
[0028]
Next, the procedure for processing the inner 11 from the inner material 10 using the inner manufacturing apparatus A for boots configured as described above will be described in detail.
First, the tip of the inner material 10 is pulled out from the roll cartridge 21 on one end side (left side in FIG. 2). Then, the drawn inner material 10 is drawn downward by the feeding roller mechanism 22.
That is, the inner material 10 is supplied downward with its leading end side suspended.
[0029]
When the lower end portion 10a of the inner material 10 is detected by the position sensor 43, the driving roller 22a of the feeding roller mechanism 22 is stopped by the instruction from the control unit (not shown) that has received the detection signal, and the inner material 10 is simultaneously fed. Stops.
[0030]
Next, the cutting blade 41 of the cutting mechanism 40 moves forward and comes into contact with the receiving plate 42, whereby the lower end portion 10a side of the inner material 10 is cut. This cut portion is the hamper portion 12 that is not used as a product, and falls into the collection container 90 below.
And the rear-end opening part 11b of the inner 11 is formed in the inner raw material 10 above the cutting blade 41 (refer Fig.4 (a)).
[0031]
After the processing by the cutting mechanism 40, the movable blade receiving die 32 of the fusion cutting mechanism 30 moves forward and comes into contact with the fusion cutting blade 31, so that the lower portion of the inner material 10 than the fusion cutting blade 31 is located. Is cut off. At this time, the tubular inner material 10 is fused in a closed manner by the heat of the fusion cutting mechanism 30 substantially simultaneously with the cutting by the fusion cutting blade 31.
Therefore, the portion of the inner material 10 cut off becomes the inner 11 having the rear end opening 11b on the lower end side and the front end closing portion 11a on the upper end side when the inner material 10 is dropped (see FIG. 4B). .
[0032]
The inner 11 cut and fused by the fusion cutting mechanism 30 receives the air pressure ejected from the ejection nozzle 46, thereby cooling and solidifying the tip closing portion 11 a and being guided downward.
[0033]
Next, the tip end side of the drop-off bar 33 rotates from the upper side to the lower side with respect to the fusion cutting blade 31. Therefore, after the processing by the fusion cutting mechanism 30, the tip closing portion 11a of the inner 11 adheres to the fusion cutting blade 31 or the inner material 10 above the movable blade receiving die 32 by heat, or When the tip closing portion 11a is stretched into a thread shape by heat and the thread portion adheres to the fusion cutting blade 31 or the inner material 10 above the movable blade receiving die 32, the inner 11 is paid off by the payout bar 33.
[0034]
Then, the dropped inner 11 is accumulated in the collection container 90 together with the hump portion 12 dropped by the processing by the cutting mechanism 40.
Thereafter, the feeding operation of the inner material 10 by the feeding roller mechanism 22, the detection of the lower end portion 10 a of the inner material 10 by the position sensor 43 and the stop of the feeding roller mechanism 22, and the opening of the rear end opening 11 b of the inner 11 by the cutting mechanism 40 are performed. The above-described operations are repeated in the order of processing and processing of the tip closing portion 11a by the fusion cutting mechanism 30, and about 10 inners 11 are manufactured per minute.
[0035]
According to an example of the above embodiment, the fusion cutting mechanism 30 is cut into the cutting mechanism 40 so that the inner 11 is processed in the order of the rear end opening portion 11b and the front end closing portion 11a (see FIG. 4A). However, the fusion cutting mechanism 30 is set to the lower side so that the inner 11 is processed in the order of the front end closing portion 11a and the rear end opening portion 11b (see FIG. 4B). It is also possible to arrange the fusion cutting blade 31 upside down.
However, in the case of this configuration, if the length of the hamper portion 12 ′ to be cut by the fusion cutting mechanism 30 is not secured long, the shorter and lighter hamper portion 12 ′ can be melted by the fusion cutting mechanism 30 or the fusion cutting mechanism 30. Since it may adhere to the inner raw material 10 above the cutting / cutting blade 31 and may not drop due to its own weight, the above-described configuration is preferable.
[0036]
【The invention's effect】
Since the present invention is configured as described above, the following effects can be obtained.
According to the first invention, the inner material is fed from the inner material supply unit and is supplied to the processing position by the fusion cutting mechanism and the cutting mechanism in a suspended state.
First, of the fusion cutting mechanism and the cutting mechanism, the lower end side of the inner is processed by one mechanism arranged on the lower side, and then the upper end side of the inner is processed by the other mechanism arranged on the upper side.
The processed inner falls downward due to its own weight and is collected by a collection container or the like.
Therefore, according to the present invention, by utilizing the weight of the inner material effectively, a mechanism for feeding the inner material to a processing position by the fusion cutting mechanism and the cutting mechanism, and a mechanism for storing the processed inner in a collection container or the like Etc. can be made into a simple structure with few power sources.
[0037]
Furthermore, according to the second invention, by arranging the fusion cutting mechanism above the cutting mechanism, the inner is processed in the order of the rear end opening portion and the front end closing portion. Compared to the reverse case (when the cutting mechanism is above the fusion cutting mechanism), the inner material cut off by the fusion cutting mechanism can be secured longer, and the processed inner is dropped by its own weight. Can be made easier.
That is, when the cutting mechanism is above the fusion cutting mechanism and the inner is processed in the order of the front end closing part and the rear end opening part, the part cut off by the lower fusion cutting mechanism is This is a hamper part of the inner material, and this hump part is usually lightened because it is shortened as much as possible to improve the yield, and it adheres to the fusion cutting mechanism and the lower end of the upper inner material and falls. There is a possibility that it will not.
However, according to the present invention, after the rear end opening is cut by the cutting mechanism, the front end closing portion is fused and cut by the fusion cutting mechanism. Therefore, the part cut off by the fusion cutting mechanism is the inner product part in which a predetermined length is secured, and is heavier than the above-described hump part.
In addition, since the fusion cutting mechanism is disposed above the cutting mechanism, when the inner or the above-mentioned hump portion is accumulated in a mountain shape in the lower collection container or the like, the accumulated inner or The hamper portion does not come into contact with and adhere to the fusion cutting mechanism, and a large amount of the recovery container can be secured.
[0038]
Further, according to the third invention, since the cutting mechanism can be moved up and down, the mechanism for manufacturing the inner having different length dimensions can be made a simple structure.
That is, for example, when an attempt is made to move the fusion cutting mechanism up and down, since the heat generating device is provided, the mechanism becomes complicated.
[0039]
Furthermore, according to the fourth invention, when the inner material in one roll cartridge is used up, the used roll cartridge can be easily replaced with another roll cartridge before use by a sliding operation. .
[0040]
Furthermore, according to the fifth aspect, after the processing by the fusion cutting mechanism, the fusion cutting portion of the inner material below the fusion cutting mechanism is heated so that the inner cutting portion above the fusion cutting mechanism is heated. Adhering to the material, the fusion cutting mechanism or the like, or the fusion cutting part is stretched into a thread shape by heat, and the inner part of the upper part from the fusion cutting mechanism is the inner material or the fusion cutting mechanism. Even if the inner material does not fall due to being attached to the inner surface, etc., the inner material can be surely dropped by being wiped off by the dropping bar.
[0041]
Furthermore, according to the sixth invention, after processing by the fusion cutting mechanism, the inner material below the fusion cutting mechanism can be cooled by the gas ejected from the ejection nozzle and blown downward. Therefore, it is possible to prevent the fusion cutting portion of the inner material below the fusion cutting mechanism from being stretched into a thread shape by heat, and the fusion cutting mechanism is cut by the pressure of the gas ejected from the ejection nozzle. The inner material can be reliably dropped.
