[0001]

[Industrial applications]

 The present invention relates to a woven fabric cutting machine used when, for example, the used clothes that have been collected are processed to produce industrial waste.

[0002]

[Problems to be solved by conventional techniques and devices]

 FIG. 4 is a view showing the entire outer shape of a conventional woven cloth cutting machine of this type. In the figure, reference numeral 1 is a base, and 2 is a protective case mounted and fixed to the base 1 via a frame 3, a part of which serves as a cover 2a, which can be opened and closed by a hinge mechanism. Reference numeral 2b is a guide portion which is integrally formed with the protective case 2 and whose tip is finished in a curved surface. Reference numeral 4 is a rotary cutter mounted in the protective case 2, and a blade is formed on the peripheral edge thereof. Reference numeral 5 is a bearing of the rotary cutter 4. Reference numeral 6 denotes a motor mounted and fixed to the base 1, the rotating shaft of which is connected to the rotating shaft of the rotary cutter 4 via a transmission belt 7 to drive the rotary cutter 4 to rotate at a desired speed in the direction of the arrow. .

Next, a procedure of cutting work will be described. It should be noted that the second-hand clothes, which are the woven fabrics to be cut here, are collected by a specialized trader and have been subjected to treatments such as washing and drying. By the way, using the above-mentioned woven cloth cutting machine, it is necessary to cut into a substantially rectangular woven cloth within the size range required for industrial waste, but the recovered used clothes are classified into several types according to their fiber quality. However, the shapes are various. Therefore, this cutting work is completely manual work that the operator appropriately processes according to the shape size of each used clothing, and the work efficiency using the woven cloth cutting machine greatly affects the productivity of waste cloth manufacturing. .

However, the conventional woven cloth cutting machine cannot be said to have sufficiently high work efficiency. That is, in the cutting of used clothes here, the original annular shape is exclusively cut open to form a flat shape. As shown in FIG. 5, an example of the posture of the worker during cutting work is shown in FIG. Is fixed, it is necessary for the worker to grasp both side portions of the used clothing D near the portion to be cut with both hands and guide the portion to be cut to the cutting position C in order. As a result, depending on the size of the used clothes, the operator needs to push the used clothes forward (in the direction of the arrow in FIG. 5) by sequentially changing the grip position of the used clothes as the cutting progresses.

In this case, the size at which the cutting can be pushed with one grip is naturally limited in terms of safety and safety of the work, and it depends on the shape size of the second-hand clothes and the heat kneading degree of the worker. Depending on the situation, it is usually necessary to re-grip multiple times to cut one place.

For this reason, the work efficiency of cutting is low and the degree of fatigue of the worker is high, so that the productivity of waste manufacturing remains below a certain level.

The present invention has been made to solve the above problems, and an object thereof is to obtain a woven cloth cutting machine capable of significantly improving the working efficiency of the cutting. .

[Means and Actions for Solving the Problems]

 The woven fabric cutting machine according to the invention of claim 1 guides the planned cutting portion of the woven fabric to be cut to the cutting position, and therefore the woven fabric cutting surface placed on the side of the woven fabric introduction surface formed on the workbench is cut. It is equipped with a moving mechanism that moves the woven fabric from the outside in the radial direction to the inside. In this case, the worker puts the woven fabric to be cut on the workbench, guides the cutting start part of the portion to be cut to the cutting position and starts cutting, and then the woven fabric also automatically advances in accordance with the progress of cutting. If the worker does not stop, the cutting end part is cut.

Further, the moving mechanism of the woven cloth cutting machine according to the invention of claim 2 is a pair of pulleys which are arranged in front of and behind the woven cloth introducing surface and are rotatable about an axis parallel to the axis of the rotary cutter. A belt spanned between the two pulleys and a drive source for rotating and driving one of the two pulleys, and the cloth to be cut is moved by the moving operation at the upper position of the belt. Is.

Further, in the cloth cutting machine according to the invention of claim 3, a roller arranged so as to sandwich the cloth between the upper surface of the belt and the roller, and a downward pressing force is applied to the roller. It is equipped with a pressing mechanism consisting of an urging means. In this case, the roller increases the frictional force between the woven fabric and the belt, so that the woven fabric can be moved more reliably.

According to a fourth aspect of the present invention, there is provided a woven fabric cutting machine in which a drive source for rotationally driving a rotary cutter and a drive source for rotationally driving a pulley are shared. Therefore, for example, only one motor is required as a drive source, which is economical.

【Example】

 Example 1. 1 is a diagram showing a main part of a woven cloth cutting machine according to a first embodiment of the present invention. It should be noted that parts not directly related to the gist of the present invention, such as the mounting part of the base 1, etc., are omitted in the drawings, and the same or corresponding parts as in the conventional ones are designated by the same reference numerals and their individual explanations are omitted. 2 (1) is a view seen from a section taken along the line AA of FIG. 1, and FIG. 2 (2) is a figure seen from a section taken along the line BB of FIG.

In both figures, 8 is a frame as a work table which is fixedly attached to a base 1 (not shown in FIGS. 1 and 2) so as to sandwich the rotary cutter 4 from both sides with a predetermined gap. The upper surface of the frame 8 is horizontal and constitutes a woven fabric introduction surface 9 on which a portion to be cut of used clothes to be cut is placed, and both ends of the frame 8 support a shaft of a pulley to be described later.

Reference numerals 10 and 11 are arranged between the frame 8 and a frame 12 which is paired with the frame 8 and fixed to the base 1 in the same manner. A belt spanned between the pulleys 10 and 11, which is made of a material such as rubber and has caterpillar-shaped irregularities formed on the outer peripheral surface. The arrows in the figure indicate the directions of rotation and movement. The frame 12 is not shown in FIG. Although not shown, the pulley 11 is rotationally driven by a motor 6 that drives the rotary cutter 4 via a transmission mechanism having an appropriate gear ratio, and the pulley 10 is driven by the pulley 11 via a belt 13. It

Reference numeral 14 is a guide portion fixed to the ends of the frames 8 and 12 so as to cover the ends of the frames 8 and 12 and the pulley 10, and the tip is formed in a curved shape, and the upper surface thereof is the frame. It is formed at the same level as the upper surfaces of 8 and 12 and constitutes a part of the woven cloth introducing surface 9.

Next, the operation, that is, the outline of the cutting work using this woven cloth cutting machine will be described. As in the conventional case, the operator grasps both side portions near the portion to be cut of the used clothes to be processed with both hands and moves the cutting start portion of the portion to be cut to the cutting position C so as to cover the guide portion 14. Lead. When the front end of the used clothes comes into contact with the surface of the belt 13 which is rotating and moved, the used clothes are forcibly sent to the front by the belt 13 and, at the same time, the central tip portion reaches the cutting position to start cutting. After that, the woven fabric is sequentially pushed forward by the belt 13, the cutting operation progresses automatically, and when the fabric passes through the cutting end portion, the woven fabric is cut and separated into right and left and falls downward.

Although the operation has been described in detail above, the point is that the operator puts a portion of the used clothing that is to be cut on the upper surface of the guide portion 14, and starts cutting by gently pressing down on both sides of the used clothing and pressing the hand. If guided to this point, after that, the cutting operation will proceed automatically even if you release your hand, which will greatly improve the work efficiency and reduce the fatigue of the worker, which is advantageous in terms of work safety.

The traveling speed of the belt 13 may be set in consideration of the shape and size of the used clothes to be processed, the familiarity of the operator, etc., but the result of trial by the inventor is about 30 to 50 m. Good results were obtained at about / min.

Example 2. FIG. 3 shows a main part of a woven cloth cutting machine according to a second embodiment of the present invention. The difference from the first embodiment is that used clothes on the belt 13 are held by rollers 15 from above. is there. As shown in FIG. 3, the roller 15 is pivotally supported on one end of the support rod 16, and the other end of the support rod 16 is pivotally supported on the cover 2 a of the protective case 2, for example. Therefore, when used clothes are fed between the roller 15 and the belt 13, the roller 15 presses the used clothes against the belt 13 by its own weight, and the friction force between the used clothes and the belt 13 is correspondingly increased. Will increase and the used clothing will be sent to the destination more reliably. Although the roller 15 is pressed downward by its own weight in FIG. 3, a spring or the like may be used separately and the roller 15 may be pressed by the stored force.

In each of the above-mentioned embodiments, the rotary cutter 4 and the pulleys 10, 11 are rotationally driven by the single motor 6, but the required rotational speed and the mounting position of both, and the other devices It is also possible to use a method in which each motor is driven by a separate motor because of the relationship with the components of the above. Further, in each of the above-described embodiments, description has been made on the assumption that used clothes are cut and processed to manufacture an industrial waste, but it goes without saying that the present invention is not limited to these applications.
