Reference numeral 37 denotes a drive source motor, and its output is transmitted to a drive mechanism composed of rotating wheels 35b and 35c attached to the structural member 35a and a timing belt 35d (see FIGS. 9 to 1). As a result, the left and right opening / closing movements of the spreading clamps 28 and 29 are performed. Reference numeral 38 denotes the above-mentioned transport conveyor, and 39 denotes a processing device for large-sized cloths transported by the transport conveyor, for example, a folding machine.

  Furthermore, in the present invention, there is provided a suction means 40 that exerts a suction force on the large-sized cloth W that has been input to the input conveyor 12. The suction means 40 is on the lower side of the input conveyor 12 at the position where the large-sized cloth transferred to the input conveyor is input, and an upper suction portion 41 that exerts a suction force on the upper side portion of the large-sized cloth, A lower suction portion 42 that exerts a suction force on the lower side portion of the large-sized fabric and biases it in the direction of the introduction roll 44 disposed below the front surface of the input conveyor 12 is provided.

  In the figure, 43 is a suction fan as a suction drive source, and 45 is a suction box. The suction box 45 communicates with the inside of the lower suction portion 42 by the ventilation partition plate 42a, and exerts a shaping action on the lower side portion of the large-sized cloth that is wound inside with the help of the rotation of the introduction roll 44. A suction part damper 46 controls the suction force in the suction means 40.

  The introduction of the large-sized cloth W by the apparatus 10 of the present invention configured as described above will be described with reference to FIG. In the state of FIG. 6, the lifting body 22 is in the loading position located on the front side of the loading conveyor 12, and the left and right lifting clamps 24, 25 are closest to each other and are equidistant on the left and right with respect to the loading center line CL. positioned. Therefore, the operator is approaching the lifting clamp 24 approaching at the low input position L with the upper side t of the large fabric W facing the downstream side with the lower side portion of the large fabric W in contact with the floor. , 25, the large cloth W can be easily attached by one person.

  Next, the lifting clamps 24 and 25 to which the large cloth W is attached move upward and are lifted to the lifting position H. In the state shown in FIG. 7, the lower side b is in a state where the lower side portion of the large-sized fabric W hardly drags the floor, and even when the variable side portion is biased as shown in FIG. The center of W and the input portion center line CL are substantially coincident. When this operation is finished, the large-sized cloth W is lowered to the low loading position L, and is in a state for depositing to the spread clamps 28 and 29 (see FIG. 8).

  The spread clamps 28 and 29 are large cloths W in which the spread spread portion 13 is advanced toward the lift portion 11 by the operation of the back and forth movement mechanism 30 and is bent to an angle close to a right angle to the downstream side. And hold the portion of the upper side t. In the state of FIG. 9, the lifting clamps 24 and 25 after the holding are released and moved upward to create a working space for the clamps 28 and 29 (FIG. 10). Is completed.

  After receiving the large fabric W, the spread clamps 28 and 29 have a state in which the clamp opening / closing mechanism 35 moves outward along the guide member 36 so that the large fabric W is expanded to the left and right at the upper side t. (FIG. 11). FIG. 5 is a bird's-eye view of this state, and it can be seen that the large-sized cloth W is spread left and right at the upper side t. In addition, at this stage where the centering of the large-sized cloth W has been completed, even if the lower side portion of the large-sized cloth W comes in contact with the floor and is loosened, the shaping shape or the like is not affected.

  The spread clamps 28 and 29 start to move in the downstream direction due to the backward movement of the back-and-forth movement mechanism 30, and the suction damper 46 of the lower suction part 42 opens, so that the suction force of the suction means 40 reaches the large cloth W. And the introduction roll 44 rotates clockwise in the figure (FIG. 12). For this reason, the large-sized cloth W receives a suction force in the vicinity of the middle portion thereof, and the lower side portion is caught and enters the suction box 45 almost instantaneously (FIG. 13B). In this process, as described above, the upper side portion of the large-sized cloth W is being drawn onto the input conveyor 12 by the spread clamps 28 and 29, and the portion is sucked through the conveyor to the upper suction portion 41. The cloth W has moved to the feeder side as a whole (FIG. 13).

  Accordingly, when almost half of the large-sized cloth W moves to the input conveyor 12 due to the retraction of the spread clamps 28 and 29, the holding by the spread clamps 28 and 29 becomes unnecessary and is released. In this way, the transfer to the input machine side is completed and the input of the large-sized cloth W is completed. At this stage, since the front elevation part 11 is already open, it becomes possible to attach the next large cloth W '. The apparatus 10 of the present invention can be used for manual input. In this case, the lifting body 22 is lifted up to the lifting position H in advance, and the spreader 13 is moved back to the retreat limit position (see FIG. 14). The worker P puts the large-sized cloth W ″ directly on the feeding conveyor 12 in a state where the suction means is operated. It is suggested by the above description that the operation of the apparatus of the present invention is performed.
