Description

The present invention relates to a rebel machine.

Conventionally, a roll spreader for spreading a part of a raw fabric (a cloth wound in a roll with respect to a core material) on a roll spread table (flat plate) flatly and without wrinkles has been known. ing. In this type of rolling machine, for example, a first roller used for moving on a rolling table, a second roller for rotating the raw fabric to feed the dough from the raw fabric, and a rolled dough are rolled. It is provided with a third roller for sending out to a table and placing it, and a fourth roller for unraveling and sending out the dough between the second roller and the third roller.

Then, the roll spreader moves on the roll spread table by rotating the first roller, and rotates the second roller to the fourth roller along with the movement to move the dough from the raw fabric onto the spread table. It is configured so that it can be sent out. Here, the fourth roller is connected to the second roller by a timing belt or the like so as to passively rotate in synchronization with the rotation of the second roller.

Such a roll spreader is used in the garment manufacturing process. Such a rolling machine cuts the dough unwound from the raw fabric at a predetermined timing. As a result, parts (fabric for cutting) are created. At the time of manufacturing this raw fabric, the dough is wound around the core material so as to form a roll under a predetermined tension. Therefore, immediately after the dough is unwound from the raw fabric, tension remains in the dough.

The tension remaining on the dough unwound from the raw fabric disappears from the dough over time, which causes the dough to shrink. If cutting is performed before the shrinkage of the fabric is completed, the parts obtained by the cutting will shrink, and there is an inconvenience that the dimensions of the parts will be incorrect. Therefore, in order to solve this problem, a rebel machine including a transport belt for transporting the dough wound between the rollers and a vibrator for vibrating the transport belt has been proposed (for example, Patent Document 1). reference).

Then, after the fabric 13 is sent from the original fabric 2 onto the rolling table 3 by the raw fabric support portion 6 and the transport portion 7, the carriage 5 is moved in the direction of the arrow 26 while the fabric 13 is continuously delivered. .. As a result, the dough 13 is spread on the spreading table 3.

After that, the carriage 5 is stopped at a predetermined timing (for example, the timing when the carriage 5 is moved to the transport position by a predetermined amount on the extension table 3), and the cutting portion 8 cuts the dough 13. As a result, the dough 13 on the rolling table 3 is separated from the original fabric 2 (the fabric 13 being conveyed by the conveying portion 7), and the parts (cutting fabric) 13a independent of the original fabric 2 are provided. It becomes.

Subsequently, the carriage 5 is moved in the direction of arrow 27 so as to return to the initial position on the extension platform 3. Next, the operation for providing the part 13a independent of the original fabric 2 as described above is performed again. This operation is repeated a plurality of times while the spreader 1 is in use. In this way, as a result of using the spreader 1, it is possible to bring about a state in which the parts 13a are spread out and a plurality of parts 13a are stacked on the spreader table 3.

Next, the transport unit 7 in the present embodiment will be described in more detail.

FIG. 2 is a side view of the transport belt 41 in the transport unit 7. FIG. 3 is a partially enlarged view of FIG. 2 (a view showing an enlarged portion of the convex portion of the transport belt 41). FIG. 4 is a plan view of the transport belt 41 in the transport unit 7. As shown in FIGS. 1, 2, 3 and 4, the transport unit 7 further includes a vibrator 71 in addition to the transport belt 41, the third roller 42, and the fourth roller 43.

The vibrator 71 is configured to be able to apply vibration to the material 13 being conveyed, which is placed on the mounting surface 11. In the present embodiment, in order to apply this vibration, the vibrator 71 is described in detail when the transport belt 41 rotates around the third roller 42 and the fourth roller 43 in the direction of the arrow 76 in FIG. Is configured to be able to vibrate its upper 41c.

In the present embodiment, the vibrator 71 has a rotating body 81 and a rotating body driving unit. The rotating body 81 is composed of a square pipe having a square cross section. The rotating body 81 is arranged between the upper 41c and the lower 41d of the transport belt 41 in the vertical direction of the transport belt 41, and is in the width direction (arrow 75 in FIG. 4) orthogonal to the transport direction (arrow 46 direction) of the fabric 13. (Direction) is extended.

The rotating body 81 is rotatably supported by the rotating shaft 85 with respect to the bogie main body 21. When the rotating body 81 rotates around the rotating shaft 85, it comes into intermittent contact with the transport belt 41. Specifically, the rotating body 81 is adapted to intermittently contact the central portion of the upper portion 41c of the transport belt 41 with respect to the length direction of the transport belt 41 (the transport direction of the fabric 13).

The rotating body 81 is provided with a plurality of corner portions 81a (four in the present embodiment). The corner portions 81a are arranged at predetermined intervals in the circumferential direction of the rotating body 81. Then, when the rotating body 81 is rotated, only each corner portion 81a of the rotating body 81 comes into contact with the upper portion 41c of the conveying belt 41 so as to come into contact with the upper portion 41c of the conveying belt 41 from the back surface side.

The rotating body driving unit has a rotating shaft 85 and a driving source such as a motor. The rotating body driving unit is connected to the rotating body 81 in a state where the rotating body 85 is coaxially fitted in the rotating body 81. The rotation drive unit is configured to be able to rotate the rotating body 81 around the rotating shaft 85 so that each corner portion 81a of the rotating body 81 comes into contact with the back surface of the upper portion 41c of the transport belt 41.

In this way, when the fabric 13 is transported by the transport belt 41 while the fabric 13 is mounted on the mounting surface 11, the vibrator 71 is used to shrink each corner of the rotating body 81 from the state after the fabric 13 is disengaged. By intermittently contacting the upper portion 41c of the conveying belt 41 with the 81a, the upper portion 41c of the conveying belt 41 is vibrated so that the fabric 13 being conveyed can be vibrated.

Further, as shown in FIGS. 2, 3 and 4, the transport belt 41 is provided with a convex portion 91. The convex portion 91 includes the first convex portion 91A. The first convex portion 91A is provided on the mounting surface 11 in order to regulate the relative movement of the fabric 13 mounted on the mounting surface 11 to the downstream side (cut portion 8 side) in the transport direction with respect to the transport belt 41. It is a thing. At least one convex portion 91 is provided.

In the present embodiment, the convex portion 91 includes a second convex portion 91B in addition to the first convex portion 91A. The first convex portion 91A is located on the mounting surface 11 (upper 41c) of the transport belt 41, and the second convex portion 91B is located on the portion (lower 41d side) of the transport belt 41 excluding the upper 41c. is there. A plurality of first convex portions 91A and a plurality of second convex portions 91B (three in the present embodiment) are provided.

The convex portions 91 (first convex portion 91A and second convex portion 91B) are arranged at predetermined intervals from the adjacent convex portions 91 in the circumferential direction of the transport belt 41. In the present embodiment, the convex portion 91 extends in the width direction of the transport belt 41 and is arranged from one end to the other end of the transport belt 41 along the width direction of the transport belt 41. Body). The convex portion 91 has a flat plate shape and protrudes from the mounting surface 11 by the thickness thereof.

As shown in FIG. 3, the convex portion 91 has a predetermined protrusion amount P as a protrusion amount with respect to the mounting surface 11. The protrusion amount P of the convex portion 91 is appropriately set so as not to hinder the movement of the fabric 13 from the original fabric support portion 6 side to the cut portion 8 side. In the present embodiment, the protrusion amount P of the convex portion 91 is set to be slightly larger than the thickness T of the transport belt 41.

In the present embodiment, the convex portions 91 are arranged at equal intervals in the circumferential direction of the transport belt 41 (the transport direction of the fabric 13). When the transport belt 41 rotates, the convex portion 91 moves in the transport direction of the dough 13 of the transport portion 7 integrally with the mounting surface 11. Specifically, the convex portion 91 is attached to the surface of the transport belt 41 by adhesion.

Further, in the present embodiment, since the transport belt 41 rotates for transporting the dough 13 as described above, the mounting surface 11 of the surface of the transport belt 41 is rotated with the rotation of the transport belt 41. The area to prepare changes. Therefore, as the transport belt 41 rotates, the convex portion 91 provided on the mounting surface 11 is replaced. Here, the convex portions 91 are always provided in a predetermined number (three) on the mounting surface 11.

Therefore, when the transport belt 41 is rotated, the convex portion 91 located on the most downstream side in the transport direction in the upper portion 41c of the transport belt 41 becomes the second convex portion 91B. Along with this, the convex portion 91 located on the upstream side in the transport direction on the lower 41d side of the transport belt 41 becomes the first convex portion 91A. In this way, the convex portion 91 can appropriately replace the first convex portion 91A with the second convex portion 91B by the rotation of the transport belt 41.

With such a configuration, when the fabric 13 is transported by the transport belt 41 while the fabric 13 is mounted on the mounting surface 11, the transport portion 7 makes the convex portion 91 function as a non-slip, and the fabric 13 acts as a non-slip. It is possible to regulate the relative movement toward the downstream side (cutting portion 8) in the transport direction. That is, the possibility that the fabric 13 placed on the transport belt 41 slides down to the downstream side in the transport direction during transport by the transport unit 7 can be suppressed.

Further, in the present embodiment, since a plurality of convex portions 91 are provided and arranged at a predetermined distance from the adjacent convex portions 91, the convex portion 91 of the fabric 13 placed on the mounting surface 11 It is possible to increase the number of points in contact with the convex portion 91 and improve the effect of the convex portion 91 as a non-slip.

Further, in the present embodiment, since the convex portion 91 is a ridge extending in the width direction of the transport belt 41 orthogonal to the transport direction (arrow 46 direction) of the fabric 13 of the transport portion 7, the transport portion 7 The fabric 13 placed on the mounting surface 11 can be efficiently brought into contact with the convex portion 91 to improve the effect of the convex portion 91 as a non-slip.

Further, in the present embodiment, since the convex portion 91 has a width direction dimension larger than the width direction dimension of the fabric 13 mounted on the mounting surface 11, the convex portion 91 is mounted on the mounting surface 11 in the transport portion 7. It is possible to surely bring the dough 13 into contact with the convex portions 91, suppress the number of the convex portions 91, and sufficiently secure the effect of the convex portions 91 as a non-slip.

In the present embodiment, the convex portion in the present invention is a convex portion 91 composed of one ridge, but the present invention is not limited to this, and for example, a part of the ridge is interrupted. 97 (see FIG. 5) may be used, 98 (see FIG. 6 (a)) consisting of a plurality of hemispheres arranged adjacent to each other and a plurality of hemispheres arranged at a predetermined interval, or 99 (see FIG. 6) having a plurality of triangular columns. (Refer to (b)).

Also, in view of the above teachings, it is clear that the present invention can take many modified and modified forms. Therefore, it should be understood that the present invention may be practiced in a manner other than that described herein, within the scope of the appended claims.
