(How to fold a piece of cloth)
Next, a method of folding the cloth piece Y by the cloth piece folding apparatus F will be described.
First, the stretched cloth pieces Y0 are supplied one by one to the first conveyor 11 of the front stage 1. In the middle of being conveyed by the first to third conveyors 11 to 13, the first folding device 31 and the second folding device 32 make a four-fold cloth piece Y <b> 1, and are conveyed to the fourth conveyor 14 of the rear stage portion 2. The The details of the folding method by the front stage 1 will be described later.

  Next, the four-fold cloth piece Y1 is folded into 32 by the third, fourth, and fifth folding devices 33, 34, and 35 while being conveyed by the fourth to eleventh conveyors 14 to 21 in the rear stage portion 2. Folded up to Y4.

  Then, the cloth pieces Y4 folded into a predetermined small area are discharged from the gate plates 41 and 41 and stacked in a predetermined number.

  Below, the detail of the folding method of the cloth piece Y by the front | former stage part 1 is demonstrated. The operation of the front part 1 has two types of operations, “front folding” and “back folding”. Here, “surface folding” is a folding method in which the surface of the cloth piece Y appears on the outside when the cloth piece Y is folded into 32 folds. Further, “back folding” is a folding method in which the back surface of the cloth piece Y appears on the outside when the cloth piece Y is folded into 32 folds.

(Folded)
First, the case of a table turn will be described.
As shown in FIG. 1, the first folding device 31 always keeps the folded plate 31 a pushed into the connecting portion between the first conveyor 11 and the second conveyor 12. Therefore, the cloth piece Y0 in the stretched state conveyed on the first conveyor 11 is changed in the conveying direction as it is, and passes between the first conveyor 11 and the second conveyor 12 to the position of the second folding device 32. Be transported.

As shown in FIGS. 4 to 6, the control device 50 operates the second folding device 32 as follows.
(1) The unfolded cloth piece Y0 passing between the first conveyor 11 and the second conveyor 12 is discharged so that the front part of the cloth piece Y0 hangs down from the end of the second conveyor 12. At this time, the folded plate 32a is waiting (temporarily stopped) at the standby position III, and the cloth piece Y0 hangs down on the back side (left side in FIG. 4) of the folded plate 32a. That is, the standby position III is a position where the cloth piece Y0 exists in the moving direction of the folded plate 32a in the next step, and is a position between the discharge position and the pushing position I of the cloth piece Y0 in the front folding operation.

  (2) The folded plate 32a is moved toward the pull-back position II at a predetermined timing. Then, the back surface of the folded plate 32a and the cloth piece Y0 are in contact with each other during the movement. Since the folded plate 32a is moved from the standby position III and brought into contact with the cloth piece Y0, the movement from the activation of the folded board 32a to the contact with the cloth piece Y0 is compared with the case where the folded plate 32a is moved from the pushing position I as in the prior art. The distance becomes shorter.

  (3) When the folded plate 32a reaches the pull-back position II, the folding position 1/4 (folded position a in FIG. 9A) from the front edge of the cloth piece Y0 is pressed by the folded plate 32a and the pressing member 36. .

  In this way, since the folded plate 32a is moved from the standby position III to press the cloth piece Y0, the moving distance from the activation (1) of the folded plate 32a to the contact (2) with the cloth piece Y0 is shortened. Therefore, the fluctuation of the moving time of the folded plate 32a is reduced, and the folding position can be pressed with high accuracy. In addition, since the bending of the folded plate 32a until it comes into contact with the cloth piece Y0 is reduced, the wind generated by the movement of the folded plate 32a becomes weak, and the shaking of the cloth piece Y0 can be reduced. As a result, folding accuracy can be improved.

  (4) When the cloth piece Y0 is further discharged while the cloth piece Y0 is pressed by the folded plate 32a and the pressing member 36, the middle part of the cloth piece Y0 is located on the front side of the folded board 32a (the right side in FIG. 5). ) Hangs down in a U shape.

  (5) The folded plate 32a is moved toward the insertion position I at a predetermined timing. Then, the tip of the folded plate 32a comes into contact with the cloth piece Y0 during the movement.

  (6) When the folded plate 32a reaches the insertion position I, the position of 3/4 from the front edge of the cloth piece Y0 (the folding position c in FIG. 9A) is the connection between the second conveyor 12 and the third conveyor 13. It is thrust into the part. As a result, the cloth piece Y0 is folded in four to form a four-fold cloth piece Y1.

  (7) After the insertion of the cloth piece Y0 is completed, the folded plate 32a is moved to the standby position III and temporarily stopped. Here, the timing at which the folded plate 32a is moved to the standby position III is set while the folded plate 32a is in contact with the cloth piece Y1. That is, it is the timing before the entire cloth piece Y1 moves between the second conveyor 12 and the third conveyor 13.

  In this way, the folded plate 32a after the cloth piece Y1 is pushed in is waited at the standby position III away from the conveyors 12 and 13, so that the folded plate 32a and the conveyor belt are not in direct contact. Therefore, deterioration of the conveyor belt due to contact with the folded plate 32a can be prevented.

(Folded)
Next, the case of reverse folding will be described.
The stretched cloth piece Y0 conveyed on the first conveyor 11 is folded in two at the center folding position (folding position b in FIG. 9A) by the first folding device 31, and then the first conveyor 11 and the second conveyor 12 are conveyed to the position of the second folding device 32.

As shown in FIGS. 7 and 8, the control device 50 operates the second folding device 32 as follows.
(1) The folded cloth piece Y0 ′ that has passed between the first conveyor 11 and the second conveyor 12 is discharged so that its front part hangs down from the end of the second conveyor 12. At this time, the folded plate 32a is waiting (temporarily stopped) at the standby position III, and the cloth piece Y0 'hangs down on the surface side (right side in FIG. 7) of the folded plate 32a. That is, the standby position III is a position where the cloth piece Y0 ′ exists in the moving direction of the folded plate 32a in the next step, and is a position between the discharge position and the pull-back position II of the cloth piece Y0 in the reverse folding operation.

  (2) The folded plate 32a is moved toward the insertion position I at a predetermined timing. Then, the tip of the folded plate 32a comes into contact with the cloth piece Y0 'during the movement. Since the folded plate 32a is moved from the standby position III and brought into contact with the cloth piece Y0, the moving distance from the activation of the folded board 32a to the contact with the cloth piece Y0 is compared with the case where the folded plate 32a is moved from the pull-back position II as in the conventional case Becomes shorter.

  (3) When the folded plate 32a reaches the indentation position I, the second conveyor 12 and the third conveyor are located at positions 1/2 (folded positions a and c in FIG. 9A) from the front edge of the cloth piece Y0 ′. 13 is inserted into the connecting portion. As a result, the cloth piece Y0 'is folded in half to form a four-fold cloth piece Y1.

  In this way, since the folded plate 32a is moved from the standby position III and the cloth piece Y0 ′ is pushed in, the moving distance from the start (1) of the folded plate 32a to the contact (2) with the cloth piece Y0 ′ is shortened. . Therefore, the fluctuation of the moving time of the folded plate 32a is reduced, and the folding position can be pushed in with high accuracy. Moreover, since the bending of the folded plate 32a until it comes into contact with the cloth piece Y0 'is reduced, the wind generated by the movement of the folded plate 32a is weakened and the shaking of the cloth piece Y0' can be reduced. As a result, folding accuracy can be improved.

  (4) After the insertion of the cloth piece Y0 is completed, the folded plate 32a is moved to the standby position III and temporarily stopped. Here, the timing at which the folded plate 32a is moved to the standby position III is set while the folded plate 32a is in contact with the cloth piece Y1. That is, it is the timing before the entire cloth piece Y1 moves between the second conveyor 12 and the third conveyor 13.

  In this way, the folded plate 32a after the cloth piece Y1 is pushed in is waited at the standby position III away from the conveyors 12 and 13, so that the folded plate 32a and the conveyor belt are not in direct contact. Therefore, deterioration of the conveyor belt due to contact with the folded plate 32a can be prevented.

(Other embodiments)
In the above embodiment, the folded plate 32a can be temporarily stopped at the standby position III by controlling the servo actuator 32c with the control device 50. However, the folded plate 32a may be temporarily stopped at the standby position III by other configurations. Good. For example, the stepping motor may be controlled by a control device. Moreover, it is good also as a structure which controls an air cylinder, a hydraulic cylinder, and a hydraulic cylinder with a control apparatus. However, the position control of the folded plate 32a is easier with the servo actuator or the stepping motor. Further, a temporary stop at the standby position III may be possible by a mechanism such as using a telescopic cylinder.
