DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pleating machine for processing pleats having a jacquard pattern in which front and back folds are mixed on a work cloth, and more particularly to an improvement in a mechanism for switching the direction of a cloth feed blade. is there.

[0002]

2. Description of the Related Art As a conventional pleat machine of this kind,
For example, a pleat machine as shown in FIG. 10 is known (first conventional example). Here, a large number of cloth feed blades 52 are arranged in a row in the width direction of the work cloth 51, and a drum 53 is installed below the cloth feed blade 52. A corresponding pin 54 is attached, and the rod 55 is
, The direction of the cloth feed blade 52 can be switched.

Further, Japanese Patent Publication No. 58-51060 discloses a pleating machine in which the direction of a cloth feed blade is switched by a solenoid (second conventional example). Each switching piece is provided with a solenoid via a switching spring so that a switching piece for switching the direction of each cloth feed blade can be pulled and driven, and many sets of these are arranged in the width direction of the work cloth.

[0004]

However, according to the pleat machine of the first conventional example, every time the pleated jacquard pattern is changed, a large number of pins 54 need to be reattached to the drum 53. It took a lot of trouble and a long time.

On the other hand, in the case of the second conventional example, since the solenoid is used, the work associated with the pattern change becomes simple, but the solenoid applies a considerable load for the purpose of pulling the switching piece. , It requires a certain level of driving force. Therefore, if a solenoid having a sufficient capacity is not used, a malfunction may occur and reliability may be reduced. Further, since the switching spring is interposed between the solenoid and the switching piece, there is a problem in responsiveness at the time of switching, and there is also a problem that the machining speed cannot be increased much.

Accordingly, an object of the present invention is to enable the direction of a large number of cloth feed blades to be switched easily, reliably and with good responsiveness by means of a solenoid that does not apply a load. An object of the present invention is to provide a pleating machine capable of processing at high speed.

[0007]

In order to solve the above-mentioned problems, a pleating machine according to the present invention comprises a pair of upper and lower pressure rollers, and a plurality of cloth feed blades for feeding a work cloth between the pressure rollers. A slider connected to each of the cloth feed blades; front-rear drive means for pressing the base ends of these sliders to move in the front-rear direction; and a detachable engagement between the base end of each slider and the front-rear drive means. A solenoid comprising a movable piece and its exciting portion, and a vertical drive means for moving the slider in the vertical direction when each slider is moved forward or backward by the front-rear drive means, and the movable piece of each solenoid is The width of the cloth feed blade is equal to or smaller than the width of the cloth feed blade, and the exciting section is formed wider than the width of the cloth feed blade, and these exciting sections alternately change positions so that adjacent ones do not interfere with each other. Array It is characterized in that was.

Here, the "slider" can be connected directly to the cloth feed blade or indirectly via a rod or the like. The configuration of the “front-rear drive unit” or the “up-down drive unit” is not particularly limited, and examples thereof include a drive unit that changes the rotational motion of a motor into a reciprocating linear motion using a crank, a cam, or the like. In addition, the front in the "front-back direction" refers to the side on which the work cloth advances, and the rear refers to the opposite side. Further, as a specific example of the arrangement of the "exciting unit",
30 pieces centered on a movable piece,
An arrangement in which the angle is alternately changed every 120 degrees or the like can be given.

[0009]

According to the pleating machine of the present invention, by selectively controlling a large number of solenoids, the work associated with the change of the pleated jacquard pattern is automated. Also,
Excitation parts of each solenoid are arranged alternately at different positions so that adjacent ones do not interfere with each other.Use an excitation part that has a sufficient capacity and is wider than the width of the cloth feed blade. Can be. Also, since the movable piece of each solenoid only engages with the base end of each slider and the front-rear drive means in a detachable manner, unlike the second conventional example, there is almost no load and no driving force is required. Therefore, even if the exciting section has the same capacity as that of the second conventional example, it can be used with sufficient margin. Further, since there is no need to interpose a switching spring between the exciting portion and the movable piece as in the second conventional example, the response at the time of switching is improved, and the processing speed can be increased. Further, since the movable piece of the solenoid is formed to be equal to or narrower than the width of the cloth feed blade, even if the cloth feed blade is considerably narrow,
Correspondingly, the narrow movable pieces can be densely aligned, so that small jacquard pattern pleats can be processed on the work cloth.
