Technical field

The present invention relates to a fiber opening machine for opening a bedding such as a used futon or a bed pad to recycle a recycled product similar to raw cotton.

Background art

[0002] At present, all products are being recycled, and for example, it is obliged to disassemble automobiles, electric appliances, nosocons, and the like and use them again. The same applies to used futons. The futons are opened and recycled, and the recycled ones are mixed with new raw cotton to produce futons again.

[0003] These beddings such as comforters and mattresses, beddings such as bed pads, cushions and cushions are generally composed of cotton inside, a fabric as a surface material, and a thread for quilting. I have. Conventionally, when opening bedding products, it is impossible to open the bedding with the weaving machine as it is, and the fabric and cotton are separated manually and the fabric is opened with the fabric opening machine. In addition, cotton was opened with a cotton opener using cotton.

[0004] Therefore, when opening used bedding, it is extremely difficult to manually separate the cloth and the cotton, and the cost is enormous. There was a problem that the cost was higher. In addition, a large amount of quilted yarn remained, and the yarn could not be recycled, and such a large amount of yarn was discarded or incinerated.

[0005] In addition, if the bedding is supplied as it is to the conventional opening machine for recycling the raw materials of the bedding such as a futon and the fiber is opened, the fiber is not opened as neatly as the raw cotton. At present, it is difficult to spread the fibers and fabrics into chunks of a certain size as they are.

[0006] By the way, a card machine (carding machine) has conventionally been known as a machine for producing Shinosawa from raw cotton. For example, Patent Documents 1 and 2 disclose patent documents. No.

[0007] Patent Document 1: Japanese Patent Application Laid-Open No. 8-109524 (Patent No. 3423785) Patent Document 2: JP-A-11-189928

[0008] When used beddings such as futons and bed pads are spread by using the card machines described in Patent Documents 1 and 2, the cloth and cotton are thinned as in the case of the conventional spreaders. There is a problem that the fiber is not spread and is sent out as a lump of a certain size as it is, and it is not possible to spread finely.

The invention's effect

According to the spreader according to claim 1 of the present invention, the holding force of the upper and lower feed rollers 10, 11 is set by the pulling force of the cutting edge 7 of the metallic wire 16 of the rotating cylinder 3. If the leading end of the bedding 35 is sent out to the cylinder 3 side so that it slides, even if the fiber is opened with the metallic wire 6, as in the conventional case, Some parts are opened in this state, and it is not possible to regenerate fibrous recycled wool 51 like new wool.

However, in the present invention, since the tooth portions 19 of the upper and lower feed rollers 10 and 11 are urged so as to be engaged with the grooves 13, the cylinder 3 is rotating at a high speed, and the bedding 35 is rotated by the cutting edge 7 of the metallic wire 6. Even if the fiber is opened by pulling the leading end of the bedding 35, the bedding 35 does not slip out from the feed rollers 10, 11 unless the upper and lower feed rollers 10, 11 rotate. It is possible to open the bedding 35 neatly without causing any serious trouble, and to recycle the fibrous recycled wool 51 like a new wool.

Therefore, the used bedding 35 can be opened into a fibrous form by the weaving machine 1 in its original state without separating the used bedding 35 into the fabric and the cotton inside. Recycled raw cotton can be recycled into 51. Also, when recycling recycled cotton wool 51, only the used bedding 35 is supplied to the opening machine body 1 in the recycling process. The costs required for the industry can be significantly reduced, and low-cost recycled raw cotton 51 can be regenerated.

[0021] According to the spreader of the second aspect, the direction in which the teeth 19 of the feed rollers 10 and 11 are pointed is opposite to the direction in which the bedding 35 is fed. Is supplied and the bedding 35 is held by the upper and lower feed rollers 10 and 11, even if the bedding is opened by the cutting edge 7 of the metallic wire 6 of the cylinder 3 rotating at high speed. The bedding 35 can be held firmly and securely without being sent out between the upper and lower feed rollers 10 and 11 by sliding.

According to the spreader of claim 5, the cross-sectional shape of the upper and lower pre-stage feed rollers 10 and 11 is substantially gear-shaped, and the tooth portions 19 and the grooves 13 of the pre-stage feed rollers 10 and 11 are the same. The fact that the bedding 35 is firmly held by the rear feed rollers 70 and 71 and that the bedding 35 is firmly held by the rear feed rollers 70 and 71 allows the front feed rollers 10 and 11 and the rear The two-stage configuration of 70 and 71 is adopted, so that even if the leading end of the bedding 35 is opened with the cutting edge 7 of the metallic wire 6 of the cylinder 3, Sliding of the bedding 35 due to the pulling force of the point 7 can be more reliably prevented, the bedding 35 can be reliably opened in a fibrous form, and the recycled raw cotton 51 similar to a new one can be regenerated.

According to the spreader of claim 6, since the direction of the cutting edge 62 of the metallic wire 61 of the subsequent feed rollers 70, 71 is sharp in the direction opposite to the conveying direction of the bedding 35, The bedding 35 can be firmly held by the first-stage feed rollers 10 and 11, thereby preventing the metallic wire 6 of the cylinder 3 from slipping in the feeding direction due to the pulling force of the cutting edge 7 of the bedding 35. Can be surely opened into a fibrous form.

[0024] Further, according to the spreader of claim 9, the bag 90 for storage of the recycled raw cotton 51 is detachably attached to the air outlet of the discharge duct 50. From the blower 49, the recycled cotton wool 51 is fed into the bag 90 by the blower 49, and at the same time, the exhaust air of the blower 49 is blown through the space between the fibers of the bag 90, and the bag When the recycled cotton wool 51 becomes full in the body 90, the operation of the spreader main body 1 is stopped, and the empty bag body 90 is attached to the discharge duct 50. Therefore, it is not necessary to take out the recycled raw cotton 51 from the storage room 52 every time the bag 90 is in a desired position, for example, a card machine (carding machine). You can bring it to

[0025] According to the fiber opening machine of claim 10, the bedding product 35 does not slide to the cylinder 3 side only by the pulling force at the time of opening the leading end of the bedding product 35 with the metallic wire 6 of the cylinder 3. As described above, since the bedding 35 is firmly held by the feed rollers 10 and 11 or the subsequent feed rollers 70 and 71, the bedding 35 can be opened neatly, and a fibrous material such as new raw cotton can be obtained. Recycled raw cotton can be recycled into 51.

A vertical recess 15 is formed in the center of the base 14, and a vertical groove 16 is formed to face the inner wall surface of the recess 15.

Rectangular bearings 21 and 22 that support the shafts 17 and 18 of the upper and lower feed rollers 10 and 11 are inserted into the recesses 15 through the vertical grooves 16 and positioned in the recesses 15. It is arranged. The upper and lower bearings 21 and 22 are slidable vertically in the recess 15.

As shown in FIG. 5, shaft rods 23 are erected from the upper surface of the base 14 on both sides of the recess 15, and a screw portion 24 is threaded on the upper part of the shaft rod 23. . A flat plate-like holding plate 25 is inserted between the two shaft rods 23 through the holes (not shown), and nuts 26 are screwed into the screw portions 24 of the shaft rods 23, respectively. A coil spring-like panel 27 interposed between the upper surface of the upper bearing 21 and the upper surface of the upper bearing 21 projects downward.

[0032] Since the upper and lower bearings 21 and 22 are projected by the compression panel type panel body 27 in this manner, the upper feed roller 10 is constantly developed with respect to the lower feed roller 11, and FIG. As shown in FIG. 7, the tooth portions 19 of the upper and lower feed rollers 10 and 11 bite into the groove 13, and the feed rollers 10 and 11 are in a completely joined state.

As shown in FIG. 1 and FIG. 2, in front of the upper and lower feed rollers 10 and 11, futons such as comforters and mattresses, cushions, cushions, kotatsu futons, bed pads, skin quilts, A conveyor device 30 for feeding bedding 35 such as a bedlet is provided. The conveyor device 30 includes a belt 31 on which a bedding item 31 is placed and directly conveyed, and sprockets 32 and 33 provided at both ends of the belt 31.

[0034] Above the end of the conveyor device 30 on the feed roller 10, 11 side, the above-mentioned bedding 35 A pressing roller 41 for holding the pressing roller 41 is provided, and the pressing roller 41 is rotatably supported by a bearing 44. The cross-sectional shape of the pressing roller 41 is substantially gear-shaped, and a groove 42 is formed along the entire length of the pressing roller 41 along the axial direction. And is formed so as to protrude therethrough.

The sprockets 32 and 33, the pressing roller 41, and the feed rollers 10 and 11 are driven to rotate in conjunction with a chain or the like (not shown), rotate at the same peripheral speed, and are conveyed by the conveyor device 30. The bedding 35 to be fed is fed flat to the next feed rollers 10 and 11 while being held flat by the holding roller 41. Further, the cylinder 3 is driven at a higher speed than the number of rotations of the feed rollers 10 and 11!

The cylinder 3 is covered by a substantially cylindrical case 45, and the upper half of the case 45 is a lid 47 that can be opened and closed by a hinge 46. A feed duct 48 having a substantially funnel-shaped cross section is provided integrally with the case 45 at the rear of the case 45, and a blower 49 is provided at the narrow end of the feed duct 48. It is.

FIG. 8 shows a plan view of a comforter 36 which is an example of the bedding 35, and FIG. 9 shows an enlarged sectional view of a main part of the comforter 36. As is well known, the comforter 36 includes an inner cotton 37, a fabric 38 as a surface material, and a thread 39 for quilting the cotton 37 and the fabric 38. The comforter 36 has a relatively large thickness, and is pressed down by the pressing roller 41 of the spreader main body 1 to be fed to the next-stage feed rollers 10 and 11.

FIG. 10 shows another example of the bedding 35, in which the bed pad 56 is shown, FIG. 10 (a) is a plan view of the bed pad 56, and FIG. 10 (b) is a front view thereof. I have. FIG. 11 is an enlarged sectional view of a main part of the pad 56.

As in the case of the comforter 36, the bed pad 56 is also composed of the cotton 37 inside, the garment 38 as the outer material, and the thread 39 for quilting the cotton 37 and the fabric 38. Since the components of the bed pad 56 are the same as those of the comforter 36, the same numbers are given. In the case of this bed pad 56, the thickness is quite thin! [0039] Fig. 12 shows a so-called solid cotton 57 as a core material such as a mattress. Fig. 12 (a) is a plan view of the solid cotton 57, and Fig. 12 (b) is a front view of the solid cotton 57. Is shown. This solid cotton 57 is obtained by laminating and compressing several layers of cotton wool produced by a carding machine (carding machine) described in Patent Documents 1 and 2. The solid cotton 57 having a predetermined size is formed by cutting at the dashed line shown in FIG.

By cutting around the solid cotton 57, a square rod-shaped solid cotton piece 58 as shown in FIG. 13 is formed. Conventionally, the force of discarding the remaining hard-cut cotton pieces 58 is discarded. In the present invention, the hard-water cotton pieces 58 are also recycled. Note that the solid cotton piece 58 itself is composed only of the compressed cotton 37!

Next, the opening process or operation of the used bedding 35 by the opening device main body 1 of the present invention will be described with reference to FIG. The used bedding 35 is different from the conventional one, and the bedding 35 without separating the cotton 37, the fabric 38, and the thread 39 is placed on the belt 31 of the conveyor device 30 in its original state as it is.

The bedding 35 is conveyed by the rotation of the belt 31, and the bedding 35 is compressed by the holding roller 41 at the holding roller 41. At the same time as the rotation of the conveyor device 30 and the pressing roller 41, the upper and lower feed rollers 10, 11 and the cylinder 3, and the blower 49 are driven.

As shown in FIG. 14, the bedding 35 compressed by the pressing roller 41 is fed between the upper and lower feed rollers 10 and 11, and the teeth of the feed rollers 10 and 11 are attached to the tip of the bedding 35. Part 1 9 bites. At this time, the upper feed roller 10 feeds the leading end of the bedding 35 while moving upward against the urging force while the upper and lower feed rollers io and 11 rotate. The bedding 35 is forcibly sent out to the metallic wire 6 side of the cylinder 3 while biting the bedding 35 with the teeth 19 of the rollers 10 and 11.

The leading end of the bedding 35 sent out by the feed rollers 10 and 11 is opened by the cutting edge 7 of the metallic wire 6 of the cylinder 3 rotating at a higher speed than the rotation of the feed rollers 10 and 11.

[0042] When the bedding 35 is opened at the cutting edge 7 of the metallic wire 6, the cotton 37, the fabric 38, and the thread 39 of the bedding 35 are simultaneously opened, and the cotton 37 itself and the fabric 38 themselves become a lump. Without The fibers are mixed and opened. When this fiber is opened, it falls into the case 45 along the rotation direction of the cylinder 3 as the recycled cotton 51, which remains as a fiber or as a piece of new cotton as a lump, to a certain extent. T

The large number of recycled cotton wools 51 that have fallen into the case 45 are forcibly sent to the discharge duct 50 via the feed duct 48 and the blower 49 by the suction action of the blower 49. Recycled cotton wool 51 is fed into the discharge duct 50 by the blower 49, and is further fed into the storage room 52 from the tip of the discharge duct 50. The recycled raw cotton 51 thus opened is stored in the storage room 52.

Here, the leading end of the bedding 35 is firmly held by the upper and lower feed rollers 10, 11, and the leading end of the bedding 35 sent out by the feed rollers 10, 11 is rotating at high speed. The fiber is opened at the cutting edge 7 of the metallic wire 6 of the cylinder 3.

If the bedding 35 is opened at the cutting edge 7 of the metallic wire 6 so that it can be pulled out, the bedding 35 cannot be sent out only by the pulling force of the cutting edge 7. The bedding 35 is firmly clamped and held between the upper and lower feed rollers 10 and 11.

Therefore, even if the cylinder 3 is rotating at a high speed and the leading end of the bedding 35 is pulled and opened by the cutting edge 7 of the metallic wire 6, the conveyor device 30, the pressing roller 41, and the upper and lower feed rollers 10 The bedding 35 is not fed from the feed rollers 10 and 11 unless the and 11 rotate.

In other words, the upper feed roller 10 is biased toward the lower feed roller 11 by the panel body 27 so that the teeth 19 of the upper and lower feed rollers 10 and 11 and the groove 13 are joined together. The bedding 35 is not sent out unless the upper and lower feed rollers 10 and 11 rotate because they are biased.

[0045] Here, the pulling force of the cutting edge 7 of the metallic wire 6 of the cylinder 3 rotating at a high speed causes the holding force of the upper and lower feed rollers 10, 11 to stake and the leading end of the bedding 35 to slide. If it is sent out to the cylinder 3 side, even if it is opened with the metallic wire 6, as in the conventional case, there is a part that is opened in a lump of the same size as before. As a result, it cannot be recycled into fibrous recycled cotton wool 51 like new cotton wool. However, in the present invention, even if the cylinder 3 is rotating at a high speed and the leading edge of the bedding 35 is opened by the cutting edge 7 of the metallic wire 6, the conveyor device 30, the holding roller 41 and the vertical As long as the feed rollers 10 and 11 do not rotate, the bedding 35 is prevented from slipping out of the feed rollers 10 and 11, so that such a problem does not occur, and the bedding 35 should be opened neatly. It can be regenerated into fibrous resital wool 51 like new wool.

That is, the feed rollers 10 and 11 use the feed rollers 10 and 11 to prevent the bedding 35 from slipping toward the cylinder 3 only by the pulling force at the time of opening the leading end of the bedding 35 by the metallic wire 6 of the cylinder 3. Since the bedding 35 is firmly held, the bedding 35 can be opened neatly, and can be recycled into fibrous recycled wool 51 such as new wool.

FIG. 1 shows the case of the comforter 36 as an example of the bedding 35, and FIG. 2 shows the case of the bed pad 56 as an example of the bedding 35. Although the thickness of the bed pad 56 is small, the bed pad 56 is further pressed by the pressing roller 41 and is fed to the feed rollers 10 and 11.

In the case of the comforter 36 having a large thickness, the comforter 36 is pressed down more thinly by the pressing roller 41 and sent to the feed rollers 10 and 11.

[0047] In the above embodiment, the force described in the case of the comforter 36 and the bed pad 56 as an example of the bedding 35 is used. Similarly, it is possible to recycle the recycled raw cotton 51 similar to a new one by opening the used original shape in a fibrous state with the opener main body 1 without separating the cotton and the fabric.

In addition, the solid cotton piece 58 as shown in FIG. 13 can be opened into a fiber shape by the opening device main body 1, and in such a case, the recycled raw cotton 51 similar to a new one can be easily regenerated.

[0048] The members (batting, cloth, etc.) constituting the bedding 35 can be applied to polyester, acrylic, nylon, rayon, cotton (cotton), wool, and the like, and can be recycled in the same manner as new ones. The raw cotton 51 can be regenerated, and recycling can be achieved.

[0049] As described above, in the present embodiment, the used bedding 35 can be opened into a fibrous form in the opening device body 1 in the original state without being separated into the fabric and the cotton inside. The used bedding 35 can be recycled into recycled cotton wool 51 similar to new one. Also, When recycling recycled raw cotton 51, it is only necessary to supply used bedding 35 to the opening device 1 in the recycling process. Costs can be significantly reduced, and low-cost recycled raw cotton 51 can be regenerated.

FIGS. 15 and 16 show other examples of the feed rollers 10 and 11, in which the cross-sectional shapes of the tooth portions 19 and the grooves 13 of the feed rollers 10 and 11 are triangular. The tooth portions 19 and the grooves 13 are formed along the entire length of the feed rollers 10 and 11 along the axial direction. When the bedding 35 is not held, the tooth portions 19 and the grooves 13 of the upper and lower feed rollers 10 and 11 are provided. And eat each other!

When the bedding 35 is fed and the bedding 35 is held by the upper and lower feed rollers 10 and 11, when the bedding is opened by the cutting edge 7 of the metallic wire 6 of the cylinder 3 rotating at high speed. Also, the bedding 35 can be held firmly by the pulling force without being sent out by sliding between the upper and lower feed rollers 10 and 11.

FIG. 17—FIG. 19 show still another example of the feed rollers 10 and 11, in which the shape of the teeth 19 of the upper and lower feed rollers 10 and 11 is pointed in the direction opposite to the cylinder 3 side. That is, As shown in the plan view of FIG. 19, the tooth portions 19 of the feed rollers 10, 11 are formed integrally over the entire length along the axial direction of the feed rollers 10, 11, and the groove 13 between the tooth portions 19 is also formed. Similarly, the feed rollers 10 and 11 are recessed over the entire length along the axial direction.

In the example of the tooth portion 19, the pointed direction of the tooth portion 19 is opposite to the feeding direction of the bedding 35, so that the bedding 35 is fed and the upper and lower feed rollers 10 When the bedding 35 is held at, 11, even when the bedding is opened by the cutting edge 7 of the metallic wire 6 of the cylinder 3 rotating at high speed, the bedding 35 is fed up and down by the pulling force. It can be held firmly and reliably without being sent out between rollers 10 and 11.

FIG. 20—FIG. 22 show another example of the feed rollers 10, 11. In this example, as in the case of the metallic wire 6 of the cylinder 3, the feed rollers 10, 11 The groove 60 is formed in a spiral shape over substantially the entire length along the axial direction of the feed rollers 10 and 11, and a metallic wire 61 is provided in the groove 60 in a spiral shape. FIG. 21 shows an enlarged side view of the main part of the metallic wire 61, and the cutting edge 62 of the metallic wire 61 is pointed like the cutting edge 7 of the metallic wire 6 of the cylinder 3. The direction in which the cutting edge 62 of the metallic wire 61 is sharp is opposite to the direction in which the bedding 35 is fed, as in the case of FIG.

The bedding 35 can be firmly and reliably held by the cutting edge 62 of the metallic wire 61, which prevents the bedding 35 from being slid between the upper and lower feed rollers 10 and 11 by the pulling force.

(Second Embodiment)

Next, a second embodiment will be described with reference to FIG. In the present embodiment, the feed roller at the front stage of the cylinder 3 has a two-stage configuration, the holding force of the bedding 35 is further strengthened, and the leading end of the bedding 35 is opened with the cutting edge 7 of the metallic wire 6 of the cylinder 3. In this case, it is possible to reliably prevent the bedding 35 from being fed by the pulling force of the cutting edge 7 when the bedding is provided.

FIG. 23 shows a schematic side view of the spreader main body 1, and FIG. 24 shows a schematic plan view of the spreader main body 1. The upper and lower pre-stage feed rollers 10 and 11 are constituted by the same feed rollers as in the previous embodiment, and the upper and lower post-feed rollers 70 and 71 following the pre-stage feed rollers 10 and 11 are the same as those of the previous embodiment. Consists of a feed roller similar to that shown in Fig. 22

The first-stage feed rollers 10 and 11 and the second-stage feed rollers 70 and 71 are supported by the same bearing portion 12, and the configuration of the bearing portion 12 is shown in FIG. The configuration of the bearing unit 12 is basically the same as that shown in FIG. 5, and the description of the bearing structure of the first-stage feed rollers 10 and 11 is omitted, and the bearing structure of the second-stage feed rollers 70 and 71 will be described. Note that the bearing structures of the first-stage feed rollers 10 and 11 and the second-stage feed rollers 70 and 71 are basically the same.

[0059] The base 14 of the bearing unit 12 is fixed to the upper surface of the frame 2, and on the left side of the base 14, a shaft supporting unit 12a that supports the front-stage feed rollers 10, 11 is similar to that of the previous embodiment. On the right side of the base 14, there is provided a shaft support portion 12b for supporting the rear-stage feed rollers 70 and 71. The two shaft supports 12a and 12b have the same configuration, but are described with different numbers. A vertical recess 72 is provided in the center of the shaft support 12b, and the inner wall surface of the recess 72 is formed on the inner wall of the recess 72. Vertical grooves 73 are formed in opposing shapes.

Rectangular bearings 76, 77 that support the shafts 74, 75 of the upper and lower rear feed rollers 70, 71 are inserted into the recess 72 through the vertical groove 73, and are inserted into the recess 72. Positioned and positioned. The upper and lower bearings 76, 77 are slidable vertically in the recess 72.

As shown in FIG. 25, shafts 78 are respectively erected from the upper surfaces on both sides of the recess 72 on the right side of the base 14, and a screw portion 79 is screwed on the upper part of the shaft 78. It is engraved. A flat holding plate 82 is inserted between the two shaft rods 78 through the holes (not shown), and nuts 83 are screwed into the screw portions 79 of the shaft rods 78, respectively. A coil spring-like panel body 84 interposed between the upper surface of the bearing 76 and the upper surface of the bearing 76 projects downward.

[0061] Since the upper and lower bearings 76 and 77 are generated by the compression panel type panel body 84 in this manner, the upper feed roller 70 is constantly generated with respect to the lower feed roller 71, and FIG. As shown in FIG. 26, the cutting edges 62 of the metallic wires 61 of the upper and lower rear feed rollers 70 and 71 are in a state of being biased and abutting against the outer peripheral surfaces of each other.

Further, as for the first-stage feed rollers 10 and 11, the upper and lower bearings 21 and 22 are developed by the compression panel type panel body 27 in the same manner as the previous embodiment, so that The upper feed roller 10 constantly erupts, and as shown in FIG. 23, the teeth 19 of the upper and lower feed rollers 10, 11 bite into the groove 13, and the feed rollers 10, 11 are completely connected to each other. It is in a state.

[0062] The configuration of the spreader main body 1 other than the front-stage feed rollers 10, 11 and the rear-stage feed rollers 70, 71, which are configured in two stages, is the same as that of the previous embodiment, and thus the same reference numerals are assigned and detailed descriptions are given. Is omitted.

Next, the opening process or operation of the used bedding 35 by the opening device main body 1 of the present embodiment will be described with reference to FIGS. 23 to 27. The bedding 35 such as the used comforter 36 and the bed pad 56 is different from the conventional one in that the cotton 37 and the fabric 38 are used similarly to the previous embodiment. The bedding 35 to be separated is placed on the belt 31 of the conveyor device 30 as it is. The bedding 35 is conveyed by the rotation of the belt 31, and the bedding 35 is compressed by the holding roller 41 at the holding roller 41. At the same time as the rotation of the conveyor device 30 and the press roller 41, the upper and lower front feed rollers 10, 11, the upper and lower rear feed rollers 70, 71, the cylinder 3, and the blower 49 are driven.

The peripheral speeds of the sprockets 32 and 33, the pressing roller 41, the first-stage feed rollers 10 and 11, and the second-stage feed rollers 70 and 71 of the conveyor device 30 are the same. Also, the rotation speed of the cylinder 3 is set to a high speed based on the peripheral speed of these downstream feed rollers 70, 71, etc.

The bedding 35 compressed by the pressing roller 41 is fed between the upper and lower feed rollers 10 and 11, and the teeth 19 of the feed rollers 10 and 11 bite into the leading end of the bedding 35. At this time, the upper feed roller 10 moves upward against the urging force protruding downward, and while the upper and lower feed rollers 10 and 11 rotate, the leading end of the bedding 35 is fed to the feed roller. The bedding 35 is forcibly fed out to the rear feed rollers 70 and 71 while biting the bedding 35 at the teeth 19 of 10 and 11.

[0066] The leading end of the bedding 35 sent out from the front feed rollers 10, 11 is fed between the following rear feed rollers 70, 71, and the leading end of the bedding 35 has the metallic wire of the rear feed rollers 70, 71. The 61 cutting edges 62 bite each. At this time, the upper feed roller 70 moves upward against the urging force protruding downward, the upper and lower rear feed rollers 70, 71 rotate, and the leading end of the bedding 35 is rotated. Is forcibly sent out to the metallic wire 6 side of the cylinder 3 while biting the bedding 35 with the cutting edge 62 of the metallic wire 61 of the subsequent feed rollers 70 and 71.

The leading end of the bedding 35 sent out by the rear feed rollers 70 and 71 is opened by the cutting edge 7 of the metallic wire 6 of the cylinder 3 rotating at a higher speed than the rotation of the rear feed rollers 70 and 71.

[0067] When the bedding 35 is opened at the cutting edge 7 of the metallic wire 6, the cotton 37, the fabric 38, and the thread 39 of the bedding 35 are simultaneously opened, and the cotton 37 itself and the fabric 38 themselves become a lump. Without mixing, the fibers are mixed and opened. When opened into this fibrous form, there is a fibrous state Alternatively, like recycled cotton, it will fall into the case 45 along the rotation direction of the cylinder 3 as recycled cotton 51 that has been clumped to some extent.

Here, the leading end of the bedding 35 is firmly held by upper and lower rear feed rollers 70 and 71, and the leading end of the bedding 35 sent out by the rear feed rollers 70 and 71 rotates at high speed. It is opened at the cutting edge 7 of the metallic wire 6 of the cylinder 3. At this time, the bedding 35 is also firmly held by the first-stage feed rollers 10 and 11 before the second-stage feed rollers 70 and 71.

When the leading end of the bedding 35 is opened at the cutting edge 7 of the metallic wire 6 so that it can be removed, the bedding 35 is prevented from slipping out only by the pulling force of the cutting edge 7. The bedding 35 is firmly clamped and held by the upper and lower rear feed rollers 70 and 71 and the front feed rollers 10 and 11.

[0069] Therefore, even if the cylinder 3 is rotating at a high speed and the leading end of the bedding 35 is opened by pulling the tip of the bedding 35 by the cutting edge 7 of the metallic wire 6, the conveyor device 30, the pressing roller 41, the upper and lower front feeds As long as the rollers 10, 11 and the rear feed rollers 70, 71 do not rotate, the bedding 35 is not fed out of the rear feed rollers 70, 71!

In other words, the upper feed roller 10 is biased toward the lower feed roller 11 by the panel body 27 so that the teeth 19 of the upper and lower feed rollers 10 and 11 and the groove 13 are joined together. The upper and lower rear feed rollers 70, 71, etc. do not rotate because they are urged and at the same time are pulled and locked by the cutting edge 62 of the metallic wire 61 of the upper and lower rear feed rollers 70, 71. As long as the bedding 35 is not sent out.

[0070] In particular, since the direction of the cutting edge 62 of the metallic wire 61 of the rear feed rollers 70, 71 is sharp in the direction opposite to the conveying direction of the bedding 35, the bedding 35 is firmly held by the front feed rollers 10, 11. Can be held and therefore the metallic wire 6 of the cylinder 3 The bedding 35 can be prevented from slipping in the feeding direction due to the pulling force of the cutting edge 7, and the bedding 35 can be reliably opened in a fiber form.

Here, due to the pulling force of the cutting edge 7 of the metallic wire 6 of the cylinder 3 rotating at high speed, the tip of the bedclothes 35 slides on the holding force of the upper and lower rear feed rollers 70 and 71. If it is sent out to the cylinder 3 side, even if it is opened with the metallic wire 6, there will be a part that is opened in a lump of the same size as the original one. Fiber-like recycled raw cotton such as 51

Although the configuration of the rear feed rollers 70 and 71 has been described using the metallic wire 61, as shown in FIG. 18, the feed roller in which the teeth 19 are integrally formed without using the metallic wire 61 is used. It may be a roller.

As shown in FIGS. 28 and 29, the rear feed rollers 70 and 71 may have the same configuration as the front feed rollers 10 and 11. In the case of power, since feed rollers having the same configuration are used, the cost can be reduced.

Further, the configuration of the first-stage feed rollers 10 and 11 may be the same as that of the second-stage feed rollers 70 and 71 as shown in FIG. 26, and the first-stage and second-stage feed rollers may be combined with feed rollers of various shapes. Of course you can.

As described above, in the present embodiment, in addition to the effects of the first embodiment, the bedding product has a two-stage configuration of the front-stage feed rollers 10 and 11 and the rear-stage feed rollers 70 and 71 before the cylinder 3. Even if the top of the bedding 35 is opened with the cutting edge 7 of the metallic wire 6 of the cylinder 3, the sliding of the bedding 35 due to the pulling force of the cutting edge 7 can be further ensured. Thus, the bedding 35 can be reliably opened in a fibrous form, and the recycled cotton wool 51 as new can be regenerated.

By the way, in both of the above embodiments, the force to feed the recycled raw cotton 51 opened by the spreader main body 1 from the discharge duct 50 to the storage room 52 for storage is shown in FIG. Such a method may be used. That is, the discharge duct 50 from the blower 49 of the opening device main body 1 is bent in a substantially U-shape, and the upper end of the bag body 90 formed of cloth is attached to the discharge-side end of the discharge duct 50 at the end. It is provided detachably at 91.

In this embodiment, the recycled raw cotton 51 is blown from the discharge duct 50 by the blower 49. Is blown into the bag 90, and at the same time, the exhaust air from the blower 49 is passed through the space between the fibers of the bag 90.

Then, when the recycled cotton wool 51 becomes full in the bag body 90, the operation of the spreader main body 1 is stopped, the band 91 is removed, and the empty bag body 90 is attached to the discharge duct 50. Therefore, it is not necessary to take out the recycled cotton wool 51 from the storage room 52, and the bag 90 can be brought to a desired position, for example, a card machine (carding machine).

[0077] In each of the above embodiments, it is preferable that the bedding 35 has a certain thickness in terms of fiber opening, and it is difficult to perform fiber opening only with a thin cloth. In the main body 1 of the spreader, the thickness is small and the fabric is not suitable.
