Description

[0001] The present invention relates to a soft roll sheet cutting machine,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a soft material sheet cutting apparatus, and more particularly, to a soft material sheet cutting apparatus capable of smoothly and accurately cutting a raw material sheet fed in a roll form such as a glass wool fabric or a nonwoven fabric.

Soft fabric sheets, such as glass wool fabrics, nonwoven fabrics or foam sheets, are typically supplied in roll form and are cut and used to the desired size in a cutting device. The cut of the fabric sheet is mainly cut by a cutter blade which traverses the fabric sheet which is unwound from the fabric roll and is transported over the conveyor, or cut by the shearing action of the cutter blade that vertically moves up and down. However, when a soft fabric sheet such as a glass wool fabric, a nonwoven fabric fabric, or a foam sheet is cut, the fabric sheet is contacted with the blade, and when the fabric is sheared, the fabric sheet is pushed by the blade and slackened to be moved or chewed together with the blade, There is a problem in that it can not be accurately cut into a desired size and shape. In addition, these fabric sheets have a relatively large unit weight of the material itself compared to paper or thin film, and due to the frictional force of the material itself or the adhesive component applied to the surface, the fabric sheet is stretched by the gap between the tip of the conveyor belt and the cutter blade There is a problem that the fabric sheet can not be smoothly conveyed on the joint plate arranged to prevent the gap or to prevent the gap.

Hereinafter, preferred embodiments of the present invention will be described. FIG. 1 is a front view of an embodiment of the present invention, FIG. 2 is a partial cross-sectional view of a raw-end loading portion of the embodiment, FIG. 3 is a front end view of a conveyor belt of a raw- Fig. 6 is a front view of the cut portion, Fig. 7 is a configuration diagram of the raw roll mounting portion, and Fig. 8 is a configuration diagram of the raw friction transmission portion. As shown in the drawing, according to the present invention, there is provided a raw roll mounting portion 10 on which a raw roll 1 having a roll of a soft raw sheet 2 such as a glass wool fabric is placed, A cutter 30 for cutting the fabric sheet 2 and a fabric outlet 40 for discharging the cut fabric sheet 2 are arranged in order And a controller 50 for controlling them are provided.

The far-end roll holder 10 includes a pivot arm 12 pivotally supported at a lower portion of the cradle frame 11 and a pivot drive means 16 such as a cylinder for driving the pivot arm 12. A seating groove 14 is formed at the distal end of the pivoting arm 12 to seat the roll shaft 4 projecting sideways of the end roll 1. The pivoting arm 12 is located at the same level as the roll axis 4 of the fabric roll 1 that approaches or descends from the lower position A by means of a conveying means such as a bogie, And when it is raised to the elevated position B by the rotation driving means 16, it is positioned at the same level as the upper surface of the cradle frame 11, The roll shaft 4 is moved along the upper surface of the mount frame 11 to be mounted on the mount roll 18 formed on the upper surface thereof. At this position, the fabric roll (1) is rotated and the fabric sheet (2) is unwound.

On the other hand, the far-end feeding portion 20 includes driving rolls 24 and 25 rotatably arranged in front of and behind the upper end of the supporting frame 21 and a conveyor belt 22 wound around the driving rolls 24 and 25. As shown in FIG. 4, the drive rolls 24 and 25 have three grooves 26 formed at regular intervals along the circumferential direction, and a recessed groove 27 is formed between the V grooves 26. Then, the conveyor belt 22 is divided into four partial conveyor belts 23 at the boundaries of these relief grooves 27. A V-shaped protrusion 28 is formed at the center of the bottom surface of each of the partial conveyor belts 23 and inserted into the V-groove 26 of the driving roll 24 to be guided. As a result, even if four partial conveyor belts 23 are wound in parallel to the drive rolls 24 and 25 and rotate, they are accurately rotated without departing from the correct position. On the other hand, the evacuation grooves 27 exposed between the individual partial conveyor belts 23 are provided in the support frame 21 and are horizontally extended to come close to the cut portions of the upper and lower cutter blades 32, A plurality of guide bars 29 are provided. The height of the guide bar 29 coincides with the upper surface of the conveyor belt 22 and the trailing end of the guide bar 29 curves slightly downward so that the soft fabric sheet 2 transported on the conveyor belt 22 smoothly mounts on the guide bar 29 So that the contact area with the guide bar 29 is small and there is no problem that the conveyance is not performed properly due to the frictional force. No. 8, which is not shown, is a motor for rotating the driving roll 25.

5 and 6, the cutting portion 30 disposed next to the conveyor belt 42 includes upper and lower cutter blades 32 and 34 vertically opposed to each other on a frame 31 so as to be vertically movable, And a cutter blade driving mechanism 36 for moving the upper and lower cutter blades 32 and 34 up and down. The bending drive mechanism 36 includes a cylinder 37 provided with a rapid exhaust valve, hinge levers 38 and 39 connected to the cylinder 37 and rotated, and hinge members 38 and 39, And a link member 48 connecting the blades 32 and 34 with each other. The cylinder 37 is provided with a rapid exhaust valve so that the blade can be quickly lifted and lowered. When the cutting stroke is controlled by the controller 50 so that the lower cutter blade 34 is first raised to reach the top dead center The upper cutter blade 32 is quickly lowered to cut off the fabric sheet 2 by the shearing action, and then the upper and lower cutter blades 32 and 34 are quickly returned to the original position. According to this operation, the fabric sheet 2 can be cut in a clearance of the blade or can be cut neatly without being caught.

A safety cover 35 is provided at the entrance of the cutout 30 to prevent the user's body from being inserted into the cutout 30 by the safety cover 35. If the safety cover 35 is removed Or if it is opened, the power is cut off so that the cutting device does not operate. The controller 50 for driving the cutouts 30 is provided with an exclusive push button for reverse rotation so that when an error occurs in the operation of the conveyor belt 22 or the cutouts 30, (22) is reversed, and the reverse rotation is stopped when the hand is released from this reverse pushing button.

On the other hand, the support frame 21 disposed on both sides of the conveying path of the conveyor belt 22 of the raw material feeding section 20 is provided with a roller member 57 mounted on an elevating member 52 such as a cylinder, Is provided with a release film winding portion 51 in which a branch pipe insertion portion 58 formed in a truncated cone shape is formed. The roller member 57 is pivotally supported in one direction by the clutch bearing 56 and braked in the opposite direction. A release film recycling paper tube 6 is inserted into the paper tube insertion portion 58. The roller member 57 is configured to be able to move back and forth in the width direction by the pressurizing cylinder 59 in order to pressurize the paper tube 6. [ This branch pipe 6 is interposed between the fabric sheets 2 of the fabric roll 1 while rotating together as the roller member 57 rotates by the friction force with the conveyor belt 22 or the fabric sheet 2 placed thereon. The release film 3 can be taken up and recovered. When the fabric sheet 2 tries to move back on the conveyor belt 22 due to its own weight or other reasons, the releasing film 3 is prevented from being unwound from the branch tube 6 by the braking action of the clutch bearing 56, (2) is kept in the correct position without being reversed.

The fabric sheet 2 cut to a predetermined size in the cut-out portion 30 is discharged through a tail end discharge portion 40 composed of a subsequent conveyor belt, is loaded on a loading device or the like not shown and is transferred to the next process.
