The guide rods 13 extend to the vicinity of the magazine guide 12b disposed opposite to each other through a hollow hole provided in a side portion of the magazine frame 12a. (See FIGS. 2 and 3).
[0029]
Thus, by adjusting the amount of protrusion of the guide rod 13 in the horizontal direction with respect to the magazine frame 12a, the magazine guide 12b is locked to the magazine frame 12a by the nut 40, so that the width dimension between the left and right magazine guides 12b, 12b. W can be adjusted to a width corresponding to the width of a thin rectangular article M such as a floppy disk.
[0030]
One end of the magazine holder main body 11a is fixed at one end of the magazine holder 11 on the article cut-out side A and extends outward in the width direction of the magazine holder main body 11a so that it is outside the width end of one magazine guide 12b. A bracket 14 that protrudes to the opposite position is disposed, and a bracket 15 is erected at a tip portion of the bracket 14 opposite to the magazine holder main body 11 a so as to be substantially perpendicular to the bracket 14.
[0031]
A cylinder base 16 is provided on the upper surface of the bracket 15 so as to extend toward the center position in the width direction of the magazine holder 11 and the magazine 12. The article cutting roller unit 17 is mounted.
[0032]
That is, the article cutting roller unit 17 includes a fluid pressure cylinder 19 installed on the cylinder base 16 via the bracket 18, and the fluid pressure cylinder 19 faces forward in the article cutting direction D2 as shown in FIG. The piston rod 19a is disposed so as to be inclined downward and to be located on the upper end side.
[0033]
A knuckle 20 is attached to the upper end of the piston rod 19 a of the fluid pressure cylinder 19, and a horizontal pin 21 whose axis extends in the width direction of the magazine 12 is rotatably fitted in the knuckle 20.
[0034]
A cam clutch 22 is externally fitted to the tip of the horizontal pin 21 that protrudes toward the knuckle 20, and a cutting roller 23 is externally fitted to the cam clutch 22. In addition, a timing pulley 41 is externally fitted and fixed so as to be positioned at the knuckle 20 partway in the longitudinal direction of the horizontal pin 21, and the cylinder base 16 is parallel to the axis L 1 of the fluid pressure cylinder 19. A timing belt 39 laid in a rack shape in the direction is provided, and the teeth of the portion of the timing pulley 41 facing the timing belt 39 mesh with the timing belt 39. Further, the outer diameter d1 of the cutting roller 23 is approximately twice the outer diameter d2 of the timing pulley 41 (see FIG. 5).
[0035]
As shown in FIG. 7, the cam clutch 22 includes an outer ring 24, an inner ring 25 that is concentrically fitted to the outer ring 24 and fitted to the horizontal pin 21, and an annular shape between the inner and outer rings 25, 24.

A coil spring 28 is provided so as to give a rotational moment to R1.
[0036]
As shown in FIGS. 7 and 8, the cam 27 is formed in a semi-cylindrical shape as viewed from the axial direction of the inner and outer rings 25 and 24, and is in contact with the inner periphery of the outer ring 24. On the side, only the top is formed in an arc shape.
[0037]
Thus, the cam 27 is in contact with the inner and outer rings 25 and 24 at the contact points X and Y, and when the outer ring 24 rotates in the counterclockwise direction R1 in FIG. When engaged and rotated in the clockwise direction R2, the radius of the arc-shaped portion at the top of the cam 27 on the outer ring 24 side is gradually increased so that the outer ring 24 can idle. .
[0038]
In the cam clutch 22, when the piston rod 19 a of the fluid pressure cylinder 19 descends obliquely downward, the outer ring 24 extends so that the most advanced article M can be cut downward by the frictional force with the cutting roller 23. The cut-out roller 23 does not rotate. In the cam clutch 22, when the piston rod 19 a protrudes obliquely upward, the outer ring 24 idles counterclockwise in FIG. 1 and the cutting roller 23 is placed on the surface of the article M that has come to the forefront. On the other hand, it can roll in the same direction as the outer ring 24.
[0039]
A plate-like bracket 29 is provided on the outside of the left and right magazine guides 12b of the magazine 12, and the bracket 29 is parallel to the cutting roller 23 so as to protrude toward the center in the width direction of the magazine 12, and Two guide rollers 30 having a diameter smaller than that of the cutting roller 23 are provided so as to be rotatable two by one with respect to one bracket 29 (see FIGS. 2, 3, 9, and 13).
[0040]
As shown in FIGS. 9 and 13, one of the two guide rollers 30 on one side is slightly spaced from the outer periphery of the guide roller 30 so that the rotation center is located immediately below the rotation center of the cutting roller 23. The remaining one is slightly spaced from the outer periphery of the guide roller 30 so that the center of rotation is positioned at the same height as the center of rotation of the cutting roller 23 and on the opposite end side of the magazine 12. Is placed.
[0041]
Thus, as shown in FIG. 13, when viewed from the side, the axis L1 of the fluid pressure cylinder 19 passing through the center of the horizontal pin 21 and the axis L2 connecting the rotation centers of the two upper and lower guide rollers 30 are The imaginary straight line L3 drawn parallel to the lower end of the guide roller 30 and in contact with the outer circumferences of the rollers 30 and 30 is parallel to the axis lines L1 and L2 and is in contact with the outer circumference of the cutting roller 23. 23 and a guide roller 30 are arranged. This is because the surface of the article M at the head of the article cutting direction D2 cut out by the cutting roller 23 and the guide roller 30 is pressed with an equal force.
[0042]
A bracket 32 integrally provided with a horizontal pin 31 parallel to the guide roller 30 is provided on both sides of the magazine frame 12a at the tip end side D2 of the magazine frame 12a. Fits freely.
[0043]
As shown in FIG. 10, the receiver 33 protrudes forward from the center of rotation of the horizontal pin 31 in the article cutting direction D2 and can support the lower edge of the leading article M in the article cutting direction D2. 33a and a weight attachment member 33b extending downward from the rotation center of the horizontal pin 31, and the side surface shape is formed in a substantially inverted L shape.
[0044]
A weight 34 extending rearward in the article cutting direction D2 is attached to the outer surface of the weight attaching member 33b in the receiver 33. Thus, when the article M is not cut out, the upper surface of the receiving body 33a is placed on the top of the article M in the article cutting direction D2 by the counterclockwise rotational force applied to the receiver 33 by the weight 34 in FIG. Can support the lower edge.
[0045]
The base of the article pusher 35 is guided in the longitudinally extending guide groove 12e (see FIGS. 2 and 3) formed on the upper surface of the magazine frame 12a so that the article pusher 35 is smoothly guided along the guide groove 12e. 35a (refer FIG. 3) is inserted. The article pushing tool 35 is provided with a pushing surface 35b on the front surface of the article cutting direction D2 that has a downward slope toward the front of the article cutting direction D2 and whose inclined surfaces are parallel to the axes L1 and L2.
[0046]
On the back surface of the pressing surface 35b of the article pusher 35 that can be slid along the magazine frame 12a, a strap-like conston spring 36 wound in a coil shape and freely rewound and fed can be used as a spring body. The tip of the conston spring 36 that is housed and unwound from the article pusher 35 is connected to the lower surface of a stopper 37 that is attached to the tip of the magazine frame 12a in the article cutting direction D2 so as to be positioned in the hollow portion of the magazine frame 12a. (See FIGS. 2, 11, and 12).
[0047]
2 and 9, reference numeral 38 denotes a stopper provided on the inner surface of the front end portion of the article cutting direction D2 in the magazine guide 12b so as to stop the second article M from the top. The slope of the contacting edge is in a direction perpendicular to the plane of the article M.
[0048]
Further, although not shown, an article detection means such as an optical sensor for detecting the leading article M is provided at the leading end of the article cutting direction D2 of the magazine holder 11.
[0049]
Next, the operation of the present invention will be described.
[0050]
In the article cutting device 3 installed on the shelf 1 in FIGS. 14 to 16 when the article M is cut out, the width of the magazine guide 12b in the magazine 12 is adjusted corresponding to the width of the article M, and the article is pushed. The tool 35 is located at the rear end portion of the magazine frame 12a in the article cutting direction D2. For example, a thin rectangular article M is formed between the pressing surface 35b of the article pressing tool 35, the cutting roller 23, and the guide roller 30. Are arranged so that the front and rear surfaces are in contact with each other, and both ends in the width direction are supported on the upper surface of the magazine rail 12c of the magazine 12.
[0051]
Thus, the last article M in the article cutting direction D2 is pushed in the article cutting direction D2 by the pushing surface 35b of the article pushing tool 35 biased by the conston spring 36, and the article M in the middle part is the rear article. M is pushed in the article pushing direction D, and the article M at the head of the article cutting direction D2 is pushed by the second article M from the beginning and supported by the outer circumferences of the cutting roller 23 and the guide roller 30.
[0052]
The lower edge of the leading article M is supported on the upper surface of the receiving body 33a of the receiver 33, the lower edge of the second article M from the leading edge is supported by a stopper 38, and the piston rod 19a of the fluid pressure cylinder 19 is further supported. Is in the most prominent state.
[0053]
When the article detection means confirms that the article M is present, a command is given to the means for operating the fluid pressure cylinder 19 from the host computer, and the piston rod 19a moves downward. At this time, the inner ring 25 and the outer ring 24 of the cam clutch 22 of the cutting roller 23 can be forcibly rotated integrally with the horizontal pin 21 by the timing belt 39 and the timing pulley 41 when the piston rod 19a is lowered. Therefore, the cutting roller 23 descends together with the piston rod 19a while rotating.
[0054]
For this reason, the leading article M is forcibly sent downward by the cutting roller 23, rotates the receiver 33 in the clockwise direction in FIGS. 1 and 10, and the lower edge of the article M is detached from the receiver body 33a. As a result, the leading article M is cut out from the magazine 12 by the cutting roller 23, supplied to the transport device 2, and transported downstream by the transport device 2. At this time, since the outer diameter d1 of the cutting roller 23 is about twice the outer diameter d2 of the timing pulley 41, the outer periphery of the cutting roller 23 rotates at a speed about twice the speed of the piston rod 19a. The rotational distance of the cutting roller 23 also moves about twice as much as the movement amount of the piston rod 19a. Therefore, even if the movement amount of the piston rod 19a is small, the turning distance of the cutting roller 23 can be increased, and the article M can be cut out reliably.
[0055]
When the leading article M is cut out, the lower edge of the second article M is supported by the stopper 38, so the second article M is not cut out together with the leading article M.
[0056]
When the first article M is cut out from the magazine 12, the article M stored in the magazine 12 is pushed forward by the pushing surface 35b of the article pushing tool 35 urged by the conston spring 36, and is second from the beginning. The article M is the head and is supported by the cutting roller 23 and the guide roller 30. At this time, the article pusher 35 moves toward the article cutting direction D2 by the thickness of one article M along the magazine frame 12a.
[0057]
When the leading article M is cut out, the receiver 33 returns to the original position even if it rotates counterclockwise from the position of the phantom line in FIG. Support the lower edge of M.
[0058]
Further, when the leading article M is cut out and the second article M becomes the leading article M, the fluid pressure cylinder 19 moves in the direction in which the piston rod 19a moves up. At this time, the outer ring 24 of the cam clutch 22 of the cut-out roller 23 is lifted while idling in contact with the article M when the piston rod 19a is lifted, so that the leading article M in contact with the cut-out roller 23 is lifted upward. It will never be done.
[0059]
For this reason, the articles M are sequentially cut out from the magazine 12 and supplied to the conveying device 2 by repeatedly lowering and raising the piston rod 19 a of the fluid pressure cylinder 19.
[0060]
In the present embodiment, as in the conventional apparatus, the articles M are not stacked on top and bottom and cut out from the lowermost layer portion, but are arranged in the horizontal direction and cut out from the front end. Therefore, the article M can be cut out smoothly.
[0061]
Further, since the article M is sent forward by the article pusher 35 urged by the conston spring 36, the article M can be reliably cut out without clogging all the articles M. It is possible to cut the article M without damaging it even if it is thin or soft.
[0062]
Furthermore, by arranging a plurality of article cutting roller units 17 side by side in the width direction of the magazine holder 11, it is possible to simultaneously cut out a plurality of articles M. For this reason, a variety of articles M can be cut out efficiently in a small space. Can do.
[0063]
It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.
