An air ejection member 70 is provided at a position below the suction duct 62 on both side shielding disks 60 of the ring drum 6, and the air ejection member 70 is connected to an external exhaust blower 63.

  The air ejection member 70 and the exhaust blower 63 are capable of ejecting air downward over the entire length in the axial direction inside the ring drum 6, that is, toward the discharge port 57 between the lower portions of the front and rear closing members 55. In addition, air is blown outward from the inside to the fiber adsorption recess 5 that has been moved from the upper part to the lower part due to the rotation of the ring drum 6, and the partial basis weight fibers P in the fiber adsorption recess 5 are peeled off from the fiber adsorption recess 5. Release downward. The air ejection member 70 and the exhaust blower 63 constitute the air ejection side of the laminated air flow means 22.

Below the ring drum 6, a carry-in belt 21 for carrying in the basic fabric fibers B conveyed by the supply conveyor 37 and a partial fabric fiber P laminated on the basic fabric fibers B by the laminated air flow means 22 are conveyed. However, a temporary forming means 23 for compressing and temporarily fusing is disposed.
The carry-in belt 21 is a net conveyor belt and can flow air up and down. A suction port member 73 is provided below the forward path portion of the carry-in belt 21, and the suction port member 73 is opposed to the discharge port 57 between the lower portions of the front and rear closing members 55. It is connected to an intake blower 71 on the air suction side.

  Therefore, the partial basis weight fibers P in the fiber adsorption recess 5 are peeled off from the fiber adsorption recess 5 by the air ejected from the air ejection member 70 connected to the exhaust blower 63 and pass through the discharge port 57 onto the basic basis fiber B. The basic fabric fibers B and the partial fabric fibers P laminated in two layers are pulled by the suction port member 73 connected to the intake blower 71 together with the jet air, and compressed on the carry-in belt 21 by the suction air, It is conveyed to the temporary molding means 23 in the compressed state.

Since the gap between the compression belt 75 and the carry-in belt 21 is gradually narrowed from the rear end to the front end, the basic fabric fibers B and the partial fabric fibers P stacked in two layers are compressed up and down, and the basis weights are different. The entire length including the portion is formed to have a substantially uniform thickness.

The fibers having a different basis weight due to the basic basis fiber B and the partial basis weight fiber P are in a continuous band shape, cut to a required length after passing through the compression heating roller 76, and temporarily fused to become an intermediate product of a certain size, and press working. Sent to the process.
Next, a different-textured fiber supply method using the different-textured fiber supply device 1 will be described.
The raw cotton is supplied to the cotton insertion roller 36 and the defibrating roller 26 of the basic fabric weight supply mechanism 3 through the rough opening machine 31, the precision opening machine 32, the fixed supply box 33 and the duct 35, and the fibers are arranged in a band shape with the chute 27. The belt-shaped basic fabric fibers B are stacked on the supply conveyor 37.

  On the other hand, the raw cotton is supplied to the cotton insertion roller 43 and the defibrating roller 44 of the partial basis weight fiber supply mechanism 4 through the rough opening machine 31, the precision opening machine 32, the fixed amount supply box 33 and the duct 42, and the guide member from the defibrating roller 44 The defibrated fibers are scattered and released into the inside of the apparatus. While rotating the ring drum 6 in which a plurality of fiber adsorbing recesses 5 are formed on the outer periphery, the inside of the ring drum 6 is made negative pressure by the fiber suction means 7 and air is sucked from the inside of the guide member 8. The air carrying fibers guided to the outer periphery are adsorbed and gathered in the fiber adsorbing recess 5.

In order to slightly adjust the amount of fibers adsorbed in the fiber adsorption recess 5, the suction pressure of the intake blower 24 of the fiber suction means 7 is adjusted.
If the bottom of the fiber adsorption recess 5 formed by the surrounding blocking member 10 is formed by the porous member 9 and the size and arrangement of the holes are uniform, the adsorbed fibers have a substantially uniform thickness, When the nesting member 11a is arranged as the restricting member 11 in the fiber adsorbing recess 5, the air flow is blocked only at the portion of the nesting member 11a, and a portion without adsorbing fibers is formed.

  Since a part of the outer peripheral surface of the ring drum 6 is closed by the closing member 55, the fibers in the fiber adsorption recess 5 do not fall until reaching the lower end of the closing member 55, and the discharge port at the lower end of the closing member 55. When the pressure reaches 57, the fiber is pushed out of the fiber adsorbing recess 5 by the air blown from the air jetting member 70 of the laminated air flow means 22, and the basic weight on the carry-in belt 21 by the air suction by the suction port member 73. Laminated on the fiber B.

The partial basis weight fiber P becomes the shape of the fiber adsorption | suction recessed part 5 restrict | limited by the limiting member 11, and unites with the basic basis fiber B, and turns into a different basis weight fiber. When changing the shape of the partial basis weight fiber P, the lid 16 is opened to expose the outer peripheral surface of the ring drum 6 from the window 15, and the restriction member 11 having a different shape, structure, arrangement, etc. with respect to the ring drum 6 is used. replace.
The continuous band-shaped irregular weight fibers that have become irregular due to the basic weight fiber B and the partial weight fibers P are subjected to surface treatment and temporary treatment by the upper and lower compression heating rollers 76 while being compressed by the carry-in belt 21 and the downwardly inclined compression belt 75. Fuse.

  In addition, although fiber molded articles, such as a floor carpet of a car, are substantially square shapes in a plan view, some have different vertical and horizontal dimensions. The basic fabric weight supply mechanism 3 can change the width of the belt-like fiber by adjusting the width of the chute 27. In the partial basis weight fiber supply mechanism 4, the ring drum 6 is formed in a size that can secure the width and length of the maximum fiber molded product. When a small fiber molded product is manufactured, the closing member 10 is replaced. The required shape and number of fiber adsorption recesses 5 are formed, and the restricting member 11 is arranged in the necessary fiber adsorption recesses 5. Thereby, the intermediate product of many types of fiber molded products from which a magnitude | size differs with the one unitary fabric supply apparatus 1 can be manufactured.

FIG. 11 shows a modification of the limiting member 11.
The ring drum 6 has a structure in which a closing member 10 having a plurality of openings is provided on the surface of the porous cylindrical member 6 </ b> A of the above-described embodiment, and a limiting member 11 is provided in a fiber adsorption recess 5 having a bottom formed by the porous member 9. A masking member 11b is arranged.

The masking member 11b1 is a band plate shape without holes, is a filter member that shields a part of the air flow in the fiber adsorption recess 5, and closes the surface of the porous member 9 at the bottom of the fiber adsorption recess 5.
Unlike the nesting member 11a, the masking member 11b1 does not exclude the entry of fibers on the surface side of the fiber adsorption recess 5 (upper side of the masking member 11b1). Thinly connected fibers can be formed, and a partial basis weight fiber P having a thick fiber layer can be formed by sandwiching an extremely thin fiber layer in one fiber adsorption recess 5.

The masking member 11b2 has a strip shape with a large number of holes, is a filter member that changes a part of the air flow amount or air flow resistance in the fiber adsorption recess 5, and the porous member 9 at the bottom of the fiber adsorption recess 5 is Double mesh structure to increase air flow resistance.
Unlike the nesting member 11a and the masking member 11b1, the masking member 11b2 adsorbs fibers also on the upper side of the masking member 11b2, so that there are fewer fibers on both sides of the masking member 11b2, but the fibers are stacked and collected. A partial basis weight fiber P in which a thick fiber layer exists between two fiber adsorbing recesses 5 can be formed.

The masking member 11b3 is obtained by overlapping a fiber layer 80 on the lower surface side of a strip having a large number of holes. The porous member 9 at the bottom of the fiber adsorption recess 5 has a triple mesh structure to further increase the air flow resistance. This is a filter member that restricts a part of the air flow amount or air flow resistance in the fiber adsorption recess 5 and reduces the fiber loading volume.
The masking member 11b3 in the fiber adsorbing recess 5 has a thinner space on the surface side due to the presence of the fiber layer 80, and the fibers are also adsorbed on the upper side of the masking member 11b3. Partially-weighted fibers P in which a thick fiber layer exists with a thin fiber layer sandwiched in one fiber adsorption recess 5 can be formed.

The nesting member 11 a and the masking members 11 b 1, 11 b 2, 11 b 3 can be used in combination. One or a plurality of the nesting members 11 a 1, 11 b 2, 11 b 3 are arranged in one fiber adsorption recess 5, and the amount of fibers adsorbed in the fiber adsorption recess 5 is partially It is possible to form a different basis weight in the partial basis weight fibers P by reducing the target or the entire area, and to laminate the basic basis weight fibers B as the partial basis weight-containing partial basis weight fibers P.
In the present invention, the shape and positional relationship of each member in the embodiment and the like are best configured as shown in FIGS. However, it is not limited to the said embodiment etc., A member, a structure can be variously deformed, and a combination can also be changed.

For example, the basic fabric weight supply mechanism 3 is configured to form the basic fabric fiber B in a shape divided by a constant length in the longitudinal direction, and supply the partial fabric fiber P to an appropriate position on the short basic fabric fiber B. Also good.
The basic fabric-based fiber supply mechanism 3 and the partial fabric-based fiber supply mechanism 4 may have different material fibers or different additives.

The ring drum 6 is formed with irregularities on the surface of the sheet metal, a number of holes are drilled in the bottom of the recesses to form the porous member 9 portion, and the portion without the holes is the closing member 10 portion, which is processed into an arc shape In addition, a plurality of the arc-shaped members may be circularly arranged and assembled into a circular drum.
Further, the ring drum 6 is formed by forming the closing member 10 into a cylindrical shape having a large number of openings, overlaying it on the outer peripheral surface of a perforated plate material 6a made of punching metal, and arranging a wire mesh 6b on the opening of the closing member 10. The bottom may have a structure in which the fiber adsorption recess 5 of the porous member 9 is formed.

While rotating the ring drum 6 in which a plurality of fiber adsorbing recesses 5 are formed on the outer periphery, the inside of the ring drum 6 is made negative pressure by the fiber suction means 7 and air is sucked from the inside of the guide member 8. The air carrying fibers guided to the outer periphery are adsorbed and gathered in the fiber adsorbing recess 5.

In order to slightly adjust the amount of fibers adsorbed in the fiber adsorption recess 5, the suction pressure of the intake blower 24 of the fiber suction means 7 is adjusted.
If the bottom of the fiber adsorption recess 5 formed by the surrounding blocking member 10 is formed by the porous member 9 and the size and arrangement of the holes are uniform, the adsorbed fibers have a substantially uniform thickness, When the nesting member 11a is arranged as the restricting member 11 in the fiber adsorbing recess 5, the air flow is blocked only at the portion of the nesting member 11a, and a portion without adsorbing fibers is formed.

  Since a part of the outer peripheral surface of the ring drum 6 is closed by the closing member 55, the fibers in the fiber adsorption recess 5 do not fall until reaching the lower end of the closing member 55, and the discharge port at the lower end of the closing member 55. When the pressure reaches 57, the fiber is pushed out of the fiber adsorbing recess 5 by the air blown from the air jetting member 70 of the laminated air flow means 22, and the basic weight on the carry-in belt 21 by the air suction by the suction port member 73. Laminated on the fiber B.

The partial basis weight fiber P becomes the shape of the fiber adsorption | suction recessed part 5 restrict | limited by the limiting member 11, and unites with the basic basis fiber B, and turns into a different basis weight fiber. When changing the shape of the partial basis weight fiber P, the lid 16 is opened to expose the outer peripheral surface of the ring drum 6 from the window 15, and the restriction member 11 having a different shape, structure, arrangement, etc. with respect to the ring drum 6 is used. replace.

Fuse.

  In addition, although fiber molded articles, such as a floor carpet of a car, are substantially square shapes in a plan view, some have different vertical and horizontal dimensions. The basic fabric weight supply mechanism 3 can change the width of the belt-like fiber by adjusting the width of the chute 27. In the partial basis weight fiber supply mechanism 4, the ring drum 6 is formed in a size that can secure the width and length of the maximum fiber molded product. When a small fiber molded product is manufactured, the closing member 10 is replaced. The required shape and number of fiber adsorption recesses 5 are formed, and the restricting member 11 is arranged in the necessary fiber adsorption recesses 5. Thereby, the intermediate product of many types of fiber molded products from which a magnitude | size differs with the one unitary fabric supply apparatus 1 can be manufactured.

FIG. 11 shows a modification of the limiting member 11.
The ring drum 6 has a structure in which a closing member 10 having a plurality of openings is provided on the surface of the porous cylindrical member 6 </ b> A of the above-described embodiment, and a limiting member 11 is provided in a fiber adsorption recess 5 having a bottom formed by the porous member 9. A masking member 11b is arranged.

The masking member 11b1 is a band plate shape without holes, is a filter member that shields a part of the air flow in the fiber adsorption recess 5, and closes the surface of the porous member 9 at the bottom of the fiber adsorption recess 5.
Unlike the nesting member 11a, the masking member 11b1 does not exclude the entry of fibers on the surface side of the fiber adsorption recess 5 (upper side of the masking member 11b1). Thinly connected fibers can be formed, and a partial basis weight fiber P having a thick fiber layer can be formed by sandwiching an extremely thin fiber layer in one fiber adsorption recess 5.

The masking member 11b2 has a strip shape with a large number of holes, is a filter member that changes a part of the air flow amount or air flow resistance in the fiber adsorption recess 5, and the porous member 9 at the bottom of the fiber adsorption recess 5 is Double mesh structure to increase air flow resistance.
Unlike the nesting member 11a and the masking member 11b1, the masking member 11b2 adsorbs fibers also on the upper side of the masking member 11b2, so that there are fewer fibers on both sides of the masking member 11b2, but the fibers are stacked and collected. A partial basis weight fiber P in which a thick fiber layer exists between two fiber adsorbing recesses 5 can be formed.

The masking member 11b3 is obtained by overlapping a fiber layer 80 on the lower surface side of a strip having a large number of holes. The porous member 9 at the bottom of the fiber adsorption recess 5 has a triple mesh structure to further increase the air flow resistance. This is a filter member that restricts a part of the air flow amount or air flow resistance in the fiber adsorption recess 5 and reduces the fiber loading volume.
The masking member 11b3 in the fiber adsorbing recess 5 has a thinner space on the surface side due to the presence of the fiber layer 80, and the fibers are also adsorbed on the upper side of the masking member 11b3. Partially-weighted fibers P in which a thick fiber layer exists with a thin fiber layer sandwiched in one fiber adsorption recess 5 can be formed.

The nesting member 11 a and the masking members 11 b 1, 11 b 2, 11 b 3 can be used in combination. One or a plurality of the nesting members 11 a 1, 11 b 2, 11 b 3 are arranged in one fiber adsorption recess 5, and the amount of fibers adsorbed in the fiber adsorption recess 5 is partially It is possible to form a different basis weight in the partial basis weight fibers P by reducing the target or the entire area, and to laminate the basic basis weight fibers B as the partial basis weight-containing partial basis weight fibers P.
