Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for manufacturing a carpet capable of forming a complicated pattern on a carpet simply and at high speed.

[0002]

2. Description of the Related Art A carpet is obtained by embedding a pile loop or a cut (cut from a pile pile) into a carpet base fabric, and is manufactured by a carpet loom as shown in FIG. Since the conventional carpet loom and the carpet loom of the present invention have the same basic configuration except for the invention, the carpet loom of the present invention shown in FIG.
Is used in the description of the conventional example.

[0003] The rolled carpet backing is attached to an unloader of a carpet loom, and the carpet backing is pulled out from the winding roll. The pulled out carpet base fabric is guided to the machine base through dancer rollers, and a pile loop is implanted in this portion.

That is, a row of needles is simultaneously inserted in a line into a carpet base cloth in a state where the carpet yarn is passed through a through hole at the tip of each needle. Then, the loopers that were waiting immediately beneath rise up all at once and catch the carpet thread at the tip of the needle. When the needle is lifted and pulled out of the carpet base fabric in this state, a loop is formed on the lower surface of the carpet base fabric. In the case of cutting, the loop is cut thereafter or simultaneously with the formation of the loop.

A large number of the needles are arranged in a row at right angles to the traveling direction of the carpet base cloth, and a single row of piles is formed at regular intervals on the lower surface of the carpet base cloth as the needles move up and down. Will be. By repeating such an operation, a large number of loop rows are formed at a constant interval on the lower surface of the carpet base cloth. The carpet formed by repeating such an operation is a carpet having a plain ground pattern. . This portion is the portion B in FIG. (Of course, a carpet yarn can be patterned by using many colors.) Therefore, a carpet having a complex ground pattern formed from a plain carpet by making the carpet rows discontinuous on the way. An attempt was made to try. According to the method, a needle is shifted by one stitch of a needle guide in a direction perpendicular to a traveling direction of a carpet base cloth, and a carpet thread is implanted in a zigzag manner with respect to a carpet base cloth continuously fed in a certain direction. A method was proposed. As a result, after the needle is reciprocated (portion A in FIG. 7), a discontinuity occurs between the loop line (portion B in FIG. 7) formed before the movement, and a ground pattern is formed on the carpet surface. Will be.

Although the above-mentioned object has been achieved to some extent, the conventional apparatus has to move the entire row of needles. Therefore, the reciprocating apparatus is very large, and the reciprocating apparatus has a large size. Since the lower looper and the needle plate are fixed, the needles must be accurately inserted between the needle guides of the needle plate. , The subsequent work was interrupted), which inevitably reduced the machine speed. For example, the production speed had to be reduced to approximately one-fourth to one-fifth of the production speed for producing solid pile carpet. This is inevitably reflected in the manufacturing cost, and there is a problem that the carpet having the ground pattern must be expensive.

[0007]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art. In forming a ground pattern on a carpet, it is not necessary to reduce the machine speed and the mechanism is simple. An object of the present invention is to develop an innovative carpet manufacturing method and apparatus.

[0008]

According to the first aspect of the present invention, there is provided a carpet manufacturing method comprising the steps of: "moving a carpet base cloth (1) in a certain direction, and moving a needle (3) up and down to the carpet base cloth (1). In the method of manufacturing a carpet by implanting a carpet yarn (2), the carpet is manufactured by reciprocating a carpet backing cloth (1) in a direction perpendicular to a traveling direction in synchronization with a vertical movement of a needle (3). Carpet yarn on base cloth (1)
Planting (2) ".

According to this, when the carpet base cloth (1) is moved in one direction and the carpet yarn (2) is planted on the carpet base cloth (1), the rows of the piles (2a) are arranged at regular intervals. The pile (2a) will be formed regularly on the lower surface of (1), but if you want to swing the pile (2a) to the left or right, the needle (3) side was conventionally shaken as described above, so the implantation speed is equivalent. Although it had to be lowered, the pile (2a) row can be formed without lowering the implantation speed by shaking the carpet base cloth (1) side in synchronization with the vertical movement of the needle (3).

According to a second aspect of the present invention, there is provided a carpet manufacturing method comprising the steps of: "moving a carpet base cloth (1) in a predetermined direction, and raising and lowering a needle (3) to a carpet base cloth (1).
In the method of manufacturing a carpet by planting (2),
In synchronization with the vertical movement of the needle (3), the carpet backing cloth (1) is reciprocated in a direction perpendicular to the traveling direction and the carpet thread (2) is planted on the carpet backing cloth (1). The ground pattern is formed by switching between the case where the carpet yarn (2) is planted on the carpet base cloth (1) which is moving by moving the needle (3) up and down. "

(Part B in FIG. 7) On the other hand, in order to plant the carpet yarn (2), the carpet backing cloth (1) which is moving in synchronization with the vertical movement of the needle (3) reciprocates in the direction perpendicular to the moving direction. When the pile (2a) is moved, the eyes of the pile (2a) are displaced from the row of the regularly formed pile (2a) to form a zigzag row. (Part A in FIG. 7) By repeating this, a complicated ground pattern is formed. As described above, the eyes of the pile (2a) form a zigzag row because the carpet base fabric (1) continuously moving in one direction is reciprocated in the direction perpendicular to the traveling direction.

Further, in forming the ground pattern as described above, necessary parts for reciprocating the carpet base cloth (1) in a direction perpendicular to the traveling direction are arranged before and after the row of needles (3). Book tension roller (5) (6)
In addition to this, the moving mechanism can not only be configured extremely easily, but also because the light carpet backing cloth (1) side is moved, it is possible to easily compose a complicated ground pattern without lowering the pile planting speed. Despite the possibility, high-speed implantation work can be realized.

A third aspect of the present invention relates to an improvement of the method for manufacturing a carpet according to the first or second aspect, characterized in that "the right-and-left reciprocating movement distance can be freely changed". This makes it possible to freely change the interval (zigzag width) between the eyes of the pile (2a), and to realize a more complicated pattern.

It is a figure showing a principle.

In FIG. 1, a carpet base fabric (1) wound up in a roll shape is attached to a loader (41) of a carpet loom, and is mounted via a plurality of dancer rolls (42).
It is withdrawn from 1) and supplied to the machine base (8). In the machine stand (8), a large number of needles (3) are arranged in a row at a right angle to the direction of movement of the carpet base cloth (1), so that the needles are raised and lowered all at once and penetrate the carpet base cloth (1). It has become.

A carpet thread (2) is supplied to the tip of the needle (3), and a pile (2a) is provided immediately below the needle (3) by a looper (4) provided corresponding to the needle (3). ) Is formed on the lower surface of the carpet base fabric (1).
The carpet base cloth (1) moves continuously regardless of the vertical movement of the needle (3). Since the carpet backing (1) is composed of coarse grain, even when the needle (3) descends and penetrates the carpet backing (1), the yarn in contact with the needle (3) easily bends. There will be no resistance when the needle (3) comes out.

The needle (3) is located immediately below the needle (3).
Accordingly, a needle plate (7) in which a needle guide (7a) is formed in a skewed shape is attached to the machine base (8) to guide the needle (3). As can be seen from FIG. 3, a thin rod-shaped tension roller (5) (6) having needles (5a) (6a) protruding from its outer periphery before and after the row of needles (3) is a carpet base cloth (1). The needles (5a) and (6a) are engaged with the carpet backing cloth (1), and the carpet backing cloth (1) is interposed between the tension rollers (5) and (6). )
The carpet base fabric (1) rotates as the tension is applied to the carpet base fabric (1).

As a result, when the needle (3) pierces the carpet backing (1) to implant the pile (2a) of the carpet thread (2) as described above, the carpet backing (1) becomes loose. It does not happen. Tension roller (5) (6)
Is rotatably and slidably held by a bearing (25b). The other ends of the tension rollers (5) and (6) are rotatably held by bearings (25a) attached to the connection arm (26), and move in the axial direction together with the connection arm (26). I have.

The other end of the transmission shaft (9) is attached to a switching block (29) of the connection / disconnection mechanism (D), and reciprocates in the axial direction in accordance with the movement of the switching block (29). ing. The switching block (29) is a block having a substantially U-shaped cross section, and a switching groove (10b) of an inverted T type (of course, not limited to this and may be an L type) is formed on a side surface thereof. . The switching groove (10b) is composed of a transmission groove (10b1) and an idling groove (10b2), and the transmission groove (10b1) is a groove extending in a direction perpendicular to the transmission shaft (9) and the transmission shaft (10a). Is formed in a width that can be fitted. Therefore, when the transmission shaft (10a) reciprocates while being fitted into the transmission groove (10b1), this reciprocation is transmitted to the switching block (29) and transmitted to the transmission shaft (9).
At the same time, the switching block (29) reciprocates in the axial direction of the transmission shaft (9).

On the other hand, the idling groove (10b2) is
(9) is formed in parallel with the transmission shaft (10a) so that the transmission shaft (10a) can freely reciprocate in the idling groove (10b2) and the reciprocation of the transmission shaft (10a) is not transmitted to the switching block (29). Has become. The transmission shaft (10a) is the transmission groove of the switching groove (10b) as described above.
(10b1) and the inside of the idling groove (10b2). The movement is based on the operation of the operation block (30). The operation block (30) includes a oscillating block (30a), a rod mounting block (30b), and an oscillating shaft (30c).
The oscillating block (30a) is a block having a substantially Y-shaped cross section, and both ends of the transmission shaft (10a) are attached to both arms (30a1) of the oscillating block (30a), and together with the oscillating block (30a). It is designed to move.

A cylinder rod (31a) is mounted on the rod mounting block (30b). The oscillating block (30a) and the rod mounting block (30b) are connected via a oscillating shaft (30c). 30a) is swingably connected. As a result, when the cylinder (31) fixed to the frame of the device operates and the cylinder rod (31a) moves up and down, the operation block (3
The transmission shaft (10) fixed to the swing block (30a)
a) moves up and down, and the transmission shaft (10a) moves to the transmission groove of the switching groove (10b).
(10b1) and the idling groove (10b2). Here, a switching unit (E) is configured by the switching block (29) and the operation block (30), and a disconnection mechanism (D) is configured by the switching unit (E) and the cylinder (31) described below. I have.

The operation direction of the cylinder (31) is switched by a switching valve (32), and the above-mentioned operation block (30) is moved up and down. Further, the transmission shaft (10a) is attached to one end of the crank arm (10) as described above,
The crank arm (10) is attached to a crank plate (12) via a crank shaft (11). This allows the crank plate (12), crank shaft (11) and crank arm
(10) constitutes the crank mechanism (K). The crankshaft (11) is eccentric with respect to the drive shaft (15) of the crank plate (12), and the amount of eccentricity is the stroke of the transmission shaft (10a). The crankshaft (11) is fixed to an eccentricity adjusting plate (13) that can slide on the crank plate (12) and can be fixed at an arbitrary position on the crank plate (12). By changing the mounting position, the drive shaft (1
The stroke can be adjusted by freely changing the amount of eccentricity of the crankshaft (11) with respect to (5).

A sensor (1) is provided near the crank plate (12).
9) is provided, and by detecting the detection plate (20) attached to the crank plate (12) with the sensor (19), the rotation timing of the crank plate (12) is detected and the control unit (34) is detected. ) To control the opening and closing of the switching valve (32) in synchronization with the rotation drive source (M) of the loom. The drive shaft (15) is rotatably held on a support portion (43) of the apparatus via bearings, and a driven wheel (16) is attached to the other end, and a rotary drive source (M ) Is transmitted by a transmission means (17) connected to the crank plate (12).

Next, the operation of the first embodiment (X1) will be described. Carpet base fabric (1) pulled out from loader (41)
Is supplied to the machine base (8) through the dancer roll (42), and the rows of the piles (2a) are formed at predetermined intervals on the lower surface of the carpet backing cloth (1) by the implantation action of the needles (3). There is
In the machine stand (8), tension rollers (5) and (6) are provided on both sides of the needle (3), and the needles of the tension rollers (5) and (6) are provided.
(5a) and (6a) are hooked on the carpet base cloth (1) to apply tension to the carpet base cloth (1) at a position between the tension rollers (5) and (6).

As a result, when the needle (3) descends and penetrates the carpet backing (1) for the implantation of the carpet thread (2), the carpet backing (1) is tightened without loosening. Smooth and needle (3) carpet backing (1)
Will penetrate. Then, the looper (4) waiting below rises, catches the carpet thread (2) inserted into the tip of the needle (3), and when the needle (3) rises in that state, the carpet base cloth (1) The piles (2a) are formed in rows on the lower surface of the carpet base fabric (1). During this time, the carpet base fabric (1) is continuously fed.

Subsequently, the needle (3) is lowered, and the pile (2a) is formed on the lower surface of the carpet base fabric (1) by the same operation as described above. By repeating such an operation, a large number of rows of piles (2a) are formed at regular intervals on the lower surface of the carpet base cloth (1). This part is shown in FIG.

In this case, the tension rollers (5) and (6) do not reciprocate in the axial direction, but simply match the carpet base fabric (1).
It is only rotating while applying tension to the carpet base fabric (1). The state of the crank mechanism (K) is as shown in FIG. That is, with the cylinder (31) retracting the cylinder rod (31a), the oscillating block (30a) is pulled down together with the transmission shaft (10a), and the transmission shaft (10a) is moved to the idling groove (10) of the switching block (29).
b2). Even if the crank arm (10) performs the crank motion in this state, the transmission shaft (10a) only reciprocates in the idling groove (10b2), and the reciprocating motion is not transmitted to the switching block (29). At this time, in order to prevent the tension rollers (5) and (6) from moving in the axial direction due to another external force, the first return spring (21) and the second return spring (22)
Due to the spring balance described above, the transmission shaft (9) is held at the neutral position between the support portions (44a).

On the other hand, when it is desired to form the pile (2a) by making the next row of the pile (2a) discontinuous with respect to the row of the previous pile (2a), the needle (3) is moved up and down. (I.e., when the needle (3) is lifted up and separated from the carpet base cloth (1), the carpet base cloth (1) is moved at right angles to the traveling direction. Since (1) reciprocates at a right angle while traveling, the resultant vector is oblique to the traveling direction, so that the carpet yarn (2) is implanted in a zigzag.) The zigzag-like implantation into (1) is performed by reciprocating the tension rollers (5) and (6) at right angles to the traveling direction of the carpet base fabric (1). This is performed as follows. That is, the rotational drive source (M) of this device
Is transmitted to the driven wheel (16) by the transmission means (17), and the crank plate (12) of the crank mechanism (K) is rotated by the drive shaft (15). Crank plate as described above
Since the crankshaft (11) of (12) is eccentric, the crank arm (10) cranks. And the needle (3)
The switching valve (32) is operated in synchronization with the vertical movement of the cylinder, the cylinder rod (31a) is protruded from the cylinder (31), and the operation block (30) is lifted. This allows the arm (30a1)
The transmission shaft (10a) is fixed to the idle groove of the switching groove (10b).
It moves from (10b2) to the transmission groove (10b1).

The transmission shaft (10a) attached to the end of the crank arm (10) is attached to the arm (30a1) as described above and fits in the transmission groove (10b1) of the switching block (29). Since it is jammed, it is a switching block with the transmission shaft (10a)
(29) reciprocates, and the crank motion of the crank arm (10) is transmitted to the transmission shaft (9). Tension roller
(5) (6) is the transmission shaft via the connection arm (26) as described above.
(9), and reciprocates in the axial direction in accordance with the movement of the transmission shaft (9). At this time, since the oscillating block (30a) is supported by the rod mounting block (30b) via the oscillating shaft (30c), the oscillating motion is performed around the oscillating shaft (30c). .

Since the carpet base cloth (1) is pinned to a large number of needles (5a) (6a) protruding from the outer circumference of the tension rollers (5) (6), the tension rollers (5) (6) When 6) reciprocates in the axial direction, the carpet base cloth (1) reciprocates at right angles to the transport direction of the carpet base cloth (1). The timing of the reciprocating movement of the tension rollers (5) and (6) is synchronized with the vertical movement of the needle (3), and the eyes of the pile (2a) are shifted at every glance. By repeating this, the zigzag portion (A) of FIG. 8 is formed.

Next, a second embodiment (X2) of the present invention will be described with reference to FIG. This case is characterized in that a clutch mechanism (C) is used instead of the switching section (E). That is, the transmission shaft
(9) is connected to a slide shaft (9a) reciprocally mounted on a guide bearing (18) mounted on the support portion (44a) of the second embodiment (X2). The slide shaft (9a) and the transmission shaft (9) are connected by a connection pin (28). Further, the slide shaft (9a) is connected to the crank arm (10) via a connection pin (27). The other end of the crank arm (10) is
As in the first embodiment (X1), it is rotatably mounted on a crankshaft (11) mounted on an eccentric position of a crank plate (12).

In the clutch mechanism (C), the power-side drive shaft
(15a) and the transmission side drive shaft (15b) are connected and disconnected by the clutch plate (14a), and the connection and disconnection operation is performed by the clutch operating portion (14). Also in this case, the clutch plate (14a) is disconnected and connected in accordance with the vertical timing of the needle (3) as in the first embodiment (X1).

That is, when the row of piles (2a) formed on the carpet backing cloth (1) is single and in a plain state with a constant interval, the clutch plates (14a) are separated from each other and the power-side drive shaft (15) is separated.
The rotation force of a) is not transmitted to the transmission-side drive shaft (15b). As a result, the transmission shaft (9) is fixed to the neutral position with respect to the support (44) by the action of the first return spring (21) and the second return spring (22) as described above, and that state is maintained. . Therefore, the tension rollers (5) and (6) attached to the transmission shaft (9) via the connection arm (26) do not move in the axial direction,
It rotates while applying tension together with the carpet base fabric (1).

As a result, the state shown in FIG. 7B is continuously formed. Next, as shown in FIG. 7A, the pile (2a)
If the carpet thread (2) is implanted in the carpet backing (1) so that the eyes are discontinuous, the needle (3)
By operating the clutch operating portion (14) in accordance with the up and down directions and connecting the clutch plate (14a), the torque of the power drive shaft (15a) is transmitted to the transmission drive shaft (15b). Transmission side drive shaft (15
b) is thus rotated, causing the crank arm (10) to crank. The synchronization timing described above is based on the detection plate (2
The rotation of (0) is detected by the sensor (19) and is calculated by the control unit (34).

The crank motion of the crank arm (10) is transmitted to the tension rollers (5) and (6) via the slide shaft (9a), the transmission shaft (9) and the connection arm (26).
(5) (6) reciprocates while rotating in the axial direction.
As a result, a discontinuous pile (2a) is formed on the lower surface of the carpet base fabric (1).

Next, a third embodiment (X3) of the present invention will be described. In this case, unlike the above, a servomotor (45) is used as a driving unit, and a reciprocating mechanism (S) is employed as a mechanism for switching the rotational motion of the servomotor (45) to reciprocating motion. The reciprocating mechanism (S) includes a nut (38) reciprocally mounted on a reciprocating guide (38a) and a screw shaft (37) mounted on a motor shaft of a servomotor (45) via a coupling (39). ).

The nut (38) is fixed to one end of the transmission shaft (9) with a set screw (40). When the tension rollers (5) and (6) do not reciprocate and rotate simply while applying tension with the carpet backing cloth (1), the servo motor
(45) is stopped. On the other hand, as described above, (A)
When forming a part, needle the servo motor (45)
By rotating forward and reverse in synchronization with the reciprocation of (3), the screw shaft (37) rotates forward and reverse, and the screw shaft (3)
The nut (38) screwed into (7) reciprocates. The reciprocating motion of the nut part (38) is transmitted to the transmission shaft (9) and transmitted to the tension rollers (5) and (6) via the connection arm (26). This allows the carpet base cloth
(1) rotates in the axial direction while rotating together with the tension rollers (5) and (6) to form a portion (A) on the lower surface of the carpet base fabric (1), thereby forming a discontinuous ground pattern. Become.
