Background technology

To cut the stacked paper lined on the table into a predetermined size in the cutting machine, press one side of the stacked paper against the gauge plate at the back of the cutting blade to cut the stacked paper. The position is determined, and then the vicinity of the cutting position of the stacking paper is pressed and fixed to the table top by the clamp mechanism, the cutting blade is lowered to cut, and then the stacking paper is once separated from the gauge plate. The stack is rotated 90 or 180 degrees on the table, the stack is pressed against the gauge plate again, positioning is performed, and the stack is clamped and cut. . At this time, the gauge plate is positioned at a predetermined position for each cutting. Conventionally, various improvements have been made to the cutting machine. For example, automation of the positioning of the gauge plate for each cutting operation and the automatic operation of the gauge plate pushing the stacked paper forward after cutting have been widely implemented. Have been.

However, at present, operations such as pressing the stacking paper against the gauge plate to determine the position and rotating the stacking paper on the table still rely on humans. This operation requires skill and is dangerous This was an operation, and there were problems such as the heavy weight of the stacked paper and the need for large force depending on the size and amount of the stacked paper.

The present invention has been made based on such a demand, and it is possible to arbitrarily move or rotate the stacked paper provided on the table of the cutting machine on the table, and to use the gauge of the cutting machine. It is an object of the present invention to provide a stacking paper handling device for a cutting machine that can be pressed well on a plate and positioned.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, preferred embodiments of the present invention shown in the drawings will be described in detail.

In Figs. 1 to 3, 1 is a cutting machine, 2 is a table of the cutting machine, 3 is a cutting line by a cutting blade (not shown), and is behind the cutting line parallel to the cutting line 3. A gage plate (not shown) is provided for pressing and positioning the edge of the stacked paper. The gauge plate is movable in a direction perpendicular to the cutting line 3. Reference numeral 10 denotes a stacked paper handling apparatus embodying the present invention. The stacking paper handling device 10 has a rail 11 arranged in front of the cutting machine 1 in parallel with the cutting line 3 and a carriage 12 running on the rail 11. A guide member 13 is arranged near the rail 11 and engages with the rollers 14 on the side of the carriage 12 to prevent the carriage 12 from lifting. Stopped. A pneumatic or hydraulic cylinder 15 parallel to the rail 11 is connected to the underside of the trolley 12 to reciprocate the trolley. The rail 11 extends longer than the carriage 15 moves by the cylinder 15. This is to allow the carriage 1 2 to be kept away from the cutter 1 when the cutter 1 or the stacking paper handling device 10 is maintained or inspected.

The trolley 12 has an apron 16 at the same height as the table on the table 2 side, and together with the table 2, forms a paper support surface. The upper surface of the apron 16 has a number of air outlets so that the stacked paper can slide easily. Instead of the air blowing holes, a number of rotatable balls may be arranged, or the upper surface of the apron may be made of a material with a low coefficient of friction. The tip of the apron 16 swivels downward so as to form a clearance for cutting chips between it and the table 2. The swiveling movable part 16A has a movable part 16A. A pneumatic cylinder (not shown) is provided for turning.

On the upper surface of the trolley 12, a rotating shaft 20 parallel to the cutting line 3 of the cutting machine 1 is provided, and the rotating shaft 20 is provided with the worm wheel 21 and the worm box 22. It is connected to the reversible motor 24 with brake via the worm and belt 23 inside. The motor 24 is capable of rotating the rotary shaft 20 in both the forward and reverse directions and stopping accurately at an arbitrary position. As described later, the motor 24 rotates the holder 30 held on the rotary shaft 20. Acts to pivot about axis 20 or to stop at any position. The pivoting range of the holder 30 is about 90 degrees, and in order to regulate this range, a shaft 25 is attached to the rotating shaft 20. A pair of holders 30 are held in the rotating putta 20, and each holder 30 has two L-shaped side plates 31 fixed to the rotating shaft 20 and the side plates 31. It has a first guide shaft 32, a screw shaft 33, and a second guide shaft 34 parallel to the rotation axis 20. The first guide shaft 32 is splined and rotatable with respect to the side plate 31. A sprocket 35 is fixed at one end, and the sprocket 35 is a chain 36. Through a fixed sprocket 37 mounted on the same axis as the rotating shaft 20. The fixed bracket 37 is fixed to the carriage 12 by the bracket 38 and cannot rotate. The screw shaft 33 is also rotatable with respect to the side plate 31 and is drivingly connected to a motor 39 mounted on the side plate 31 such as a pulse motor.

The first arm 40 (see FIG. 4) is held by the first guide shaft 32, the screw shaft 33, and the second guide shaft 34. The first arm 40 is composed of linear bearings 41 1, 42 slidable in the axial direction with respect to the guide shafts 32, 34, respectively, and a ball nut 4, which is screwed with the screw shaft 33. It moves left and right in Fig. 2 by the rotation of the screw shaft 33.

In Fig. 5, the linear bearing 41 held on the first guide shaft 32 engages the spline of the first guide shaft 32 and rotates with the first guide shaft 32. The first arm 40 is rotatable. The linear bearing 41 also holds the second arm 44 rotatably. Thus, the second arm 44 is pivotable about the axis of the guide shaft 32 with respect to the first arm 40. At the end of the second arm 44, a shaft 46 parallel to the guide shaft 32 is rotatably held. Hands 4 5 (details will be described later) are fixed to 6 and held.

The shaft 46 holding the hand 45 has a sprocket 51, and the sprocket 51 is connected to the sprocket 51 on the linear bearing 41 via the chain 52, the intermediate sprocket 53, and the chain 54. Linked to 5-5. As described above, the linear bearing 41 rotates together with the spline of the first guide shaft 32, and the first guide shaft 32 connects the sprockets 35 and chains 36 at the ends. As a result, the shaft 46 of the hand 45 is connected to the fixed sprocket 37. Here, the number of teeth of two sprockets connected to each other by a chain is determined in a one-to-one relationship. Thus, in FIG. 3, no matter how the holder 30 pivots about the central axis X of the rotation axis 20, the second arm 44 does not move with respect to the first arm 40. In this manner, the shaft 46 does not rotate, and the hand 45 is always maintained at the horizontal position shown in the figure. In other words, the guide shaft 32, sprockets 35, 37, chain 36, sprockets 51, 53, 55, chains 52, 54, etc. A posture maintaining mechanism is constructed to keep 5 in a constant posture at all times. In this embodiment, a large number of tunes and sprockets are used as the attitude maintaining mechanism for maintaining the hand 45 horizontally, but other known mechanisms, for example, a link mechanism are used instead. Is also good.

A pneumatic cylinder 60 is provided between the first arm 40 and the second arm 4. As shown in Fig. 4, the pneumatic cylinder 60 is supplied with air pressure in the direction in which the piston rod extends, and usually, the pneumatic cylinder 60 is in the extended state. Is kept. Therefore, this sky In FIG. 4, the pressure cylinder 60 plays a role as a stopper that regulates the minimum value of the angle formed by the second arm 44 with respect to the first arm 40, and the second arm 44 is used as a clock. It also plays the role of pushing in the direction. When the holder 30 is pivoted clockwise about the rotation axis 20 as shown in FIGS. 8A and 8B, the second arm 44 is kept at the minimum angular position with respect to the first arm 40. The hand 45 falls while it is leaning. When the holder 30 continues to pivot even after the hand 45 descends and comes into contact with the apron 16 or the table 2, as shown in FIG. 8C, the first arm 40 of the second arm 44 continues. The hand 45 is slid on the table 2 and pushed forward. At this time, since the pneumatic cylinder 60 pushes the second arm 44 clockwise, the hand 45 is pressed onto the table 2 and does not float during movement. When the holder 30 is pivoted in the opposite direction from the position shown in FIG. 8C, the hand 45 slides back on the table 2 and the apron 16 and rises from a certain position. When the holder 30 is positioned as shown in Fig. 8C and the screw shaft 33 of the holder 30 is rotated, the first arm 40 moves along the screw shaft 33. Or, slide on the apron 16 and move left and right in Fig. 1. Thus, the pair of hands 45 move forward on the table 2 toward the gauge plate together with the pivoting of the holder 30 due to the rotation of the rotation axis 20 or move away from the gauge plate. By moving the screw shaft 33 of each holder, the holder can be individually moved on the table 2 in the direction parallel to the gauge plate, that is, in the lateral direction. The means for moving the hand 45 on the table 2 is the same as that in the illustrated embodiment. The present invention is not limited to this, and various changes can be made.

Next, the details of the hand 45 will be described with reference to FIG. The hand 45 shown in Fig. 6 is arranged on the right side in Fig. 1, and the hand 45 arranged on the left side is symmetrical to that in Fig. 6. In FIG. 6, a hand 45 is fixed to a shaft 46 and moves on the table top of the cutting machine. A vertical bin 62 is provided at the tip of the hand body 61. A paper retainer 63 held pivotally between a position extending substantially forward of the hand body and a position extending substantially laterally around the axis, and the paper retainer 63 are pivoted. It has a driving means 64 for pivoting and a paper pushing member 65 attached to the side surface of the hand body 61. It is desirable to arrange a plate made of a material with a low coefficient of friction, such as a plastic plate, on the lower surface of the hand body 61 so that the table 2 can slide smoothly on the upper surface. The paper retainer 63 is formed of a support 63A held in a bin 62, a paper push 63B held movably in the lateral direction by the support 63A, and a paper press plate 63B. It has a spring 63C that pushes away from the support 63A. The paper push plate 6 3 B is used to move the stack paper on both sides of the stack on the table 2 or to push the end face of the stack paper. The surface of the portion sandwiching both sides of the stack paper Is provided with a material having a large coefficient of friction with respect to the stacking paper _: rubber 63D, for example. The paper presser 63 shown in FIG. 6 is provided so as to be able to pivot about 90 degrees counterclockwise from a position shown in which the support body 63A extends straight ahead of the hand body 61. As the driving means 64 for pivoting the paper retainer 63, a pneumatic cylinder, a hydraulic cylinder, a torque actuator, a motor, or the like can be used. In this embodiment, a pneumatic cylinder is used. The pneumatic cylinder 64 has Sensors 68 and 69 are provided to detect that is at both ends of the reciprocating motion.

The paper pushing member 65 attached to the carrying surface of the hand body 61 is provided so that it can contact and push the rear end face of the stacked paper on the table 2. It is arranged on the left side, that is, the side of the pair of hands 45 facing each other. The shape of the paper pushing member 65 is not limited to the one shown in the drawing, and any shape can be used as long as the hand 45 can be pushed forward by contacting the end face of the stacked paper when the hand 45 is advanced. Also, it may be movable. Fig. 7 shows a movable paper pushing member 65. The paper pushing member 65 is attached to the side surface of the hand body 61 with a hinge 66, and is indicated by a solid line with a pneumatic cylinder 67. In this example, the paper push member 65 is not used when the paper push member 65 is not used. When the center of the side surface of the stacked paper is sandwiched between the pressers 63, the paper pressing member 65 does not become an obstacle, which is convenient.

Referring again to FIG. 1, the stacking paper rotating device 100 extending above the table 2 of the cutting machine 1 is held substantially at the center of the bogie 12. The stacking paper rotating device 100 has a support arm 101 mounted on a carriage 12 as shown in FIGS. 9 and 10. The support arm 101 extends above the table 2 of the cutting machine 1 and has, at its tip, a turntable 103 that can rotate around an axis perpendicular to the table 2 and a motor that drives the turntable. It has a first driving device 105. A plurality of slide bearings 107 are fixed to the lower surface of the turntable 103, and a plurality of (four in this embodiment) shafts 107 are fixed to the slide bearings 107. Are held parallel to the table 2 and movably in the axial direction.

The left paper holder 1 110 is fixed to the left end of the two shafts 109, and the right paper holder 1 1 1 is fixed to the right end of the other two shafts 109. Is done. The left paper holder 110 is connected to the piston rod 115 of the pneumatic cylinder 113 mounted on the turntable 103. Furthermore, as shown in Fig. 11, the paper holders 110, 111 are connected to the slides 117, 118 slidably held on the lower surface of the turntable 103. The two racks are connected via gears 119, 120, and 121, which are rotatably held on a turntable 103. Therefore, when one paper holder 110 is moved by the pneumatic cylinder 113, the other paper holder 111 moves in the opposite direction due to the engagement of gears and racks. . Thus, one pair of pneumatic cylinders 113 can be driven in the opposite direction so that the pair of paper holders 110, 111 approaches or moves away from each other. In other words, the pneumatic cylinder 113, the racks 117, 118, and the gears 119 to 121 constitute a second drive unit that moves the paper holder in the opposite direction.

Since the paper holders 110 and 111 and the members held by them are the same except that they are symmetrical, only one paper holder 110 will be described. In Fig. 11, Fig. 12, Fig. 13 and Fig. 13, the paper holder 110 is provided with a rotating shaft having an axis parallel to the table 2 and perpendicular to the moving direction of the paper holder 110. 1 23 is rotatably held, and a support plate 125 is fixed to the rotating shaft 123. The support plate 125 holds a paper retainer 127 having an L-shaped cross section as shown in Fig. 13 so as to be slidable and a pneumatic cylinder for driving the paper retainer 127. 1 2 9 is also retained. Therefore, the paper retainer 127 can rotate around an axis Y-Y parallel to the table 2 and perpendicular to the moving direction of the paper retainer 110. The rotating shaft 1 2 3 holds the gear 1 3 1, and this gear 1 3 1 moves to the rack 1 3 5 which is reciprocated by the pneumatic cylinder 13 3 held by the paper holder 1 110. I'm engaged. Thus, when the rack 13 35 is reciprocated by the pneumatic cylinder 13 3, the paper presser 127 moves about the axis Y-Y at right angles to the standby position parallel to the table 2. Swivels between positions. That is, the pneumatic cylinder 13 3, the rack 13 5, the gear 13 1, etc., constitute the third drive for turning the paper presser 127. The paper retainer 127 holds the both sides of the stack as described later, and a soft material such as a filter or cloth is stuck on the surface to prevent the stack from being damaged.

The turntable 10 3, the paper holder 1 110, 1 1 1 and the paper holder 1 27 at the standby position (horizontal position) are cut on table 2 as can be clearly seen from Fig. 9. Is placed at an appropriate distance from the top of the table so that it does not interfere with the movement of the stack paper. Further, when the paper presser 127 is rotated to the operating position as shown in Fig. 13 with the pneumatic cylinder 1229 retracted, the lower end is located slightly away from the upper surface of the table 2. It is manufactured in such a size that it can move downward by the operation of the pneumatic cylinder 12 and contact the upper surface of the table 2. The paper retainer 127 does not necessarily have to be movable with respect to the support plate 125. The dimension is such that when the paper retainer is turned from horizontal to vertical, the lower end of the paper retainer is almost immediately in contact with the table top. Therefore, the pneumatic cylinder 1 29 may be omitted. Next, the operation of the above device will be described. The following operations are performed automatically by a control device (not shown) or by operating the operation buttons of an operation device (not shown). These control devices and operation devices are as follows. A person skilled in the art can easily design the device to perform the operation described above, and a description of the structure will be omitted.

First, the cart 1 2 is positioned in front of the cutting machine 1. At this time, the turntable 103 of the stacking paper rotating device 100, the paper retainer holders 110, 111, the paper retainer 127, etc. occupy the positions shown by the solid lines in Fig. 9. I have. Then, as shown in Fig. 14A, the stack 4 to be cut is placed on the table 2 of the cutting machine 1 by hand or by any transport device. Next, as shown in FIGS. 8A to 8C, the rotating shaft 20 rotates to rotate the holder 30, the hand 45 is lowered onto the table 2, and the table 45 is slid on the table 2. Move forward, and at the same time, the screw shaft 33 of each holder 30 rotates to move the hand 45 in the horizontal direction. As shown in Fig. 14A, both sides of the stack 4 are held by the paper holders of the hand 45. 6 Lightly sandwich with 3. In this state, when the holder 30 is further turned and the hand 45 is advanced, the paper pushing member 65 of the hand 45 contacts the rear end of the stacking paper 4 and pushes this rear end to stack. Move the paper towards gauge plate 5. At this time, even if the stacking paper 4 is slightly inclined with respect to the gauge plate 5, the paper pushing member 65 pushes the rear end of the stacking paper 4, so that the paper can be moved without any trouble. The stacking paper 4 is automatically straightened against the gauge plate while moving, and is pressed well against the gauge plate 5. Also, at this time, since the both sides of the stacking paper 4 are sandwiched by the paper retainers 63, the stacking paper is prevented from being disturbed while the stacking paper 4 is moving. Further, the paper retainer 63 is clearly shown in FIG. As can be seen, since the paper pressing plate 63B is in contact with the side of the stacking paper via the spring 63C, it is not necessary to accurately position the hand 45 with respect to the stacking paper. Also, no excessive pressing force is applied to the children's paper. In addition, instead of using the paper pushing member 65, it is also possible to strongly sandwich the both sides of the stacking paper 4 with the paper retainer 63 and advance the stacking paper 4 by the frictional force. However, in this case, if the side of the stacking paper 4 is not parallel to the surface of the paper retainer 63, the paper will not be properly sandwiched by the paper retainer 63 and the paper will be advanced. That is difficult. Therefore, if the stacking paper 4 is oblique, it is necessary to correct it straight. However, in this embodiment, since the paper pushing member 65 that presses the rear end of the stacking paper is provided, the correction is made. The stacking paper 4 can be moved forward very quickly without any need for the adjustment and while correcting the posture of the stacking paper 4.

Next, the hand 45 moves away from the stack 4 and moves to the rear of the stack 4, and as shown in FIG. 14B, the paper retainer 63 of the hand 45 is inclined. Turn and push the trailing edge of calf 4 and press stack 4 against gauge plate 5. The pressing force at this time is the force applied by the driving means 6 4 (see FIG. 6) for pivoting the paper presser 63. The force by the driving means 64 does not apply an excessive pressing force to the rear end of the stacked paper. It is set as follows. With the paper retainer 63 pushing the trailing edge of the stack of paper, the clamp mechanism of the cutting machine operates to fix the paper, and then the paper retainer 63 moves at right angles to the hand 45. It turns in a certain direction to move away from the trailing edge of the stack, and then the cutting blade descends to cut the stack. At this point, some troubles may cause the paper retainer 63 to extend below the cutting line 3 without contacting the rear end of the stacked paper. If the clamp mechanism operates in this state, the paper When the cutting tool 63 is clamped and the cutting blade falls on it, a serious accident occurs. In order to prevent this accident, the clamp mechanism is operable only when the paper retainer 63 is in an inclined position with respect to the hand 45 as shown in Fig. 14B. . More specifically, when the paper press 63 is pivoted by the pneumatic cylinder 64 to make contact with the rear end of the stacked paper, if the paper press does not touch the rear end of the stacked paper, the paper press As shown in Fig. 6, 63 is a position extending in front of the hand 45, and the sensor of the pneumatic cylinder 64 is detected by the sensor 69. While the sensor 69 is outputting the detection signal, the clamp mechanism is not operated. Further, when the cutting blade descends, the paper presser 63 pivots in a direction away from the trailing edge of the stack of paper, returns to a position substantially perpendicular to the hand 45, and the sensor 68 changes its state. It is configured to be performed only when a signal is detected and output. With this configuration: Even if the paper presser 63 is clamped by the clamping mechanism, the cutting blade does not drop in that state.

At the end of one cut, the gauge plate is pushed out to the position for rotating the stacking paper 4 (Fig. 14C). If the paper feeding position by the gauge plate 5 is inappropriate for the rotation of the stacking paper, the both ends of the stacking paper 4 are sandwiched by the hand 45 as shown in Fig. 14A. The hand 45 may be moved forward or backward to an appropriate position. At this time, since the paper presser 127 of the stacking paper rotating device 100 is at the horizontal standby position as shown in Fig. 9, there is no hindrance to the movement of the stacking paper. Next, the paper holders 110 and 111 move away from each other, and the paper holder 127 pivots to the operating position perpendicular to the table (Fig. 14c). Then, the pneumatic cylinder 12 9 is operated to press the lower end of the paper retainer 127 onto the upper surface of the table, and in this state, the paper retainers 110 and 111 move in the direction approaching each other. By this operation, both ends of the stack 4 are gripped by the paper retainers 127 as shown in Fig. 14D and Fig. 14d. Next, while holding the stacking paper, the turntable 103 rotates 90 degrees, and the stacking paper 4 rotates 90 degrees on the table (Figs. 14E and 14e). Next, the paper retainers 1 1 0 and 1 1 1 move in the direction away from each other to release the stack of paper 4 held by the paper retainer, the paper retainer returns to its original horizontal position, and the turntable is also returned Return to the state. After the stacking paper rotating device 100 is in a state where it does not hinder the paper movement in this way, the rear end of the paper is gently lightened as shown in Fig. 14A again. The hand 45 is moved forward by pressing the holding paper 63 and pressing the stacking paper against the gauge plate. Thereafter, the same operation is repeated, and the desired cutting is performed.

After the cutting of the desired side is completed, the stacking paper 4 is pushed out by the gauge plate 5, and the stacking paper is further pulled out to the paper feeding position with the hand 45 interposed. Next, the carriage 12 moves to the right and sends out the stacking paper 4 to the position shown in FIG. 14F. If you want to send the stack 4 further to the right from this position, remove the hand 45 from the stack 4, move the bogie to the left once, and then use the back of the right hand 4 5 Press the left end of the stack 4 as shown in Fig. 14F, and move the carriage 12 to the right.
