[0023]
  When thick paper is inserted into the slit 111 by the roller 131, the winding motor 112 provided below the winding bar 11 is now activated. The motor 112 is also stopped when the winding bar 11 is rotationally driven a predetermined number of times. After the end of the cardboard is engaged with the slit 111, the motor 112 is activated to allow the cardboard to move to the outer periphery of the coiling bar 11. It is designed to be wound up by
[0024]
  Next, the spread preventing mechanism 12 will be briefly described. The spread preventing mechanism 12 has a purpose of preventing a gap from being formed between the cardboard and the winding bar 11 when the winding bar 11 is rotated, and the winding bar 11. It is provided for the purpose of preventing the end of the cardboard from coming off from the guide 133 just before the end of winding and spreading the cardboard, and is configured to press the cardboard along the outer peripheral surface of the winding bar 11. .

Has been. Further, the pressing member 122 is made of resin so as to prevent the winding bar 11 from being worn because it contacts the winding bar 11 (here, made of iron). The pressing member 122 may be formed of metal and the front surface thereof may be coated with a material having a low friction coefficient.
(B)Propeller shaftDescription of transport mechanism 2
  next,Propeller shaftThe transport mechanism 2 will be described below.Propeller shaftThe transport mechanism 2 is provided on the downstream side (left side in the figure) of the transport conveyor 4 shown in FIG. 1 and has been transported by the transport conveyor 4.Propeller shaftIs transported to the cardboard insertion work position.
[0027]
  Where thisPropeller shaftAs shown in FIGS. 1 and 2, the transport mechanism 2 includes a transport loader 21 and an axis alignment mechanism 22. Among these, the conveyance loader 21 is from the conveyance conveyor 4.Propeller shaftTo the insertion work position and to the next process after the insertion workPropeller shaftIs operated by a predetermined program.
[0028]
  As shown in FIG.Propeller shaftThe transport loader 21 includes a rail 212 mainly constructed on a frame 211, an actuator 213 extending and contracting in the vertical direction,Propeller shaftAnd an arm mechanism 214 for gripping. The arm mechanism 214 normally stands by directly above the transport conveyor 4, and this transport conveyor 4Propeller shaftIs conveyed from the right side in FIGS. 1 and 2, the actuator 213 and the arm mechanism 214 are operated,Propeller shaftIs to be gripped.
[0029]
  After that, the arm mechanism 214Propeller shaftIs lifted, the arm mechanism 214 moves on the rail 212,Propeller shaftIs placed on the work table 6. Also,Propeller shaftIs placed on the work table 6, a conveyor (not shown) on the work table 6 is operated to reach the insertion work position shown in FIG. 1.Propeller shaftIs to be transported.
[0030]
  Next, the shaft alignment mechanism 22 will be described. The shaft alignment mechanism 22 is provided at the insertion work position. Further, this axis alignment mechanism 22 has different diameters.Propeller shaftThe axial center of the winding bar 11 is always adjusted to a certain height.Propeller shaftIt is comprised so that it may correspond with the axial center.
  Specifically, as shown in FIGS. 11A and 11B, the axis alignment mechanism 22 isPropeller shaftThe two actuators 221 provided symmetrically on both sides of the actuator 221 and the upper roller 222 and the lower roller 223 provided at the tip of each actuator 221 are configured.
[0031]
  The work table 6 is assumed.Propeller shaftOf the largest diameterPropeller shaftWhen [shown by phantom lines in FIG. 11 (a)] is placed, the central axis of the winding bar 11 andPropeller shaftIt is set so that the central axis of
  On the other hand, the two rollers 222 and 223 have a central axis (that is, a maximum diameter) of the winding bar 11.Propeller shaftIt is attached at a height that is symmetric with respect to the height position of the central axis of.
[0032]
  Then, as shown in FIG.Propeller shaftBy extending toward the center of thePropeller shaftIs narrowed by the rollers 222 and 223, and the intermediate height of the upper and lower rollers 222 and 223 (the height of the point divided into two equal parts connecting the centers of the two rollers 222 and 223) andPropeller shaftThe center axis heights of these are the same. Here, the intermediate height of the upper and lower rollers 222 and 223 is equal to the height of the center axis of the winding bar, thereby reducing the diameter.Propeller shaftEven so, the heights of the central axes can be matched.
[0033]
  In addition,Propeller shaftBy always making the extension amount of the actuator 221 provided symmetrically on both sides of thePropeller shaftIt is also possible to always match the position in the width direction of the center [the left and right direction in FIGS. 11 (a) and 11 (b)].
(C) Description of the insertion mechanism 3
  Next, the insertion mechanism 3 will be described.Propeller shaftIt has been transported by transport mechanism 2Propeller shaftIt is a mechanism for inserting the wound cardboard, and is mainly composed of a hand mechanism 31 and a cardboard transport mechanism 32 (both see FIG. 7).
[0034]
  Here, the hand mechanism 31 sandwiches and holds cylindrical cardboard wound around the winding bar 11 from the outer periphery, and the cardboard transport mechanism 32 holds the cardboard gripped by the hand mechanism 31.Propeller shaftIt is transported to the side and cardboard is inserted.
  First, the hand mechanism 31 will be described. As shown in FIGS. 6 and 7, the hand mechanism 31 includes semicircular hand members (holding members) 311 and 312 and an actuator 313 that operates the hand members 311 and 312. Is provided.
[0035]
  As shown in the drawing, the hand members 311 and 312 hold the cardboard by sandwiching the winding bar 11 from both the left and right sides. By operating the actuator 313, the standby position and the virtual position shown by the solid line in FIG. 6 and FIG. The hand members 311 and 312 are driven to open and close between the work positions indicated by the lines (two-dot chain lines). The left and right hand members 311 and 312 constitute a pair of hands, and a plurality of sets of hands are provided along the axial direction of the winding bar 11 as shown in FIG.
[0036]
  The hand members 311 and 312 are respectively disposed between the pressing members 122 (see FIG. 5) of the spread preventing mechanism 12 so that the hand members 311 and 312 and the pressing member 122 do not interfere with each other. ing.
  A thin rubber sheet 314 (see FIGS. 6 and 7) is attached to the inside of the hand members 311 and 312. The inner diameters of the hand members 311 and 312 including the rubber sheet 314 are slightly larger than the outer diameter of the winding bar 11.
[0037]
  Accordingly, after the cardboard is wound around the winding bar 11, the actuator 313 is operated to move the hand members 311 and 312 to the positions indicated by phantom lines in FIG. 7, and then the actuator 121 of the spread prevention mechanism 12 is retracted. The cardboard spreads out due to elasticity, and the cardboard comes into close contact with the rubber sheet 314 inside each hand member 311, 312.
[0038]
  Then, by moving the hand mechanism 31 along the axial direction of the winding bar 11 in this state, the cardboard is separated from the winding bar 11 in a cylindrical state.
  The hand mechanism 31 holds the thick paper by a thick paper transport mechanism 32 described later.Propeller shaftTo the side. And although the detailed mechanism is not shown, the tip of the cardboardPropeller shaftOnce inserted, the hand members 311 and 312 on the tip (left end in FIG. 4) side are opened sequentially.Propeller shaftTo prevent interference.
[0039]
  Next, the cardboard transport mechanism 32 will be described. As shown in FIG. 7, the cardboard transport mechanism 32 includes a motor 321, a rack and pinion mechanism 322, a movable rail 323, a guide 324, and the like. As shown in FIGS. 2 and 7, the motor 321 is fixed on the frame 5, and a pinion gear 326 is attached to the tip of the motor 321.
[0040]
  A guide 324 is fixed to the frame 5, and a movable rail 323 is slidably engaged with the guide 324. A rack 327 is attached to the movable rail 323 in parallel with the movable rail 323 and meshes with the pinion gear 326. The movable mechanism 323 is also attached with the hand mechanism 32 described above.
[0041]
  Therefore, when the motor 321 rotates, the rail 323 moves along the guide 324 so that the cardboard held by the hand mechanism 31 is transported together with the hand mechanism 31.
  Incidentally, as shown in FIGS. 5 and 9, a pusher (pressing member) 325 is provided on one end side of the winding bar 11. This pusher 325 is a cylindrical member,Propeller shaftIt is provided to ensure that it is pushed into the end. In other words, cardboard is loaded only with the hand mechanism 32.Propeller shaftWhen trying to insert into the inside, when the last pair of hand members 311 and 312 (that is, at the right end in FIG. 4) is opened, there is no member holding the cardboard, and the cardboard is completely removed.Propeller shaftIt cannot be inserted inside.
[0042]
  Therefore, a pusher 325 is provided to ensure that the cardboard isPropeller shaftIt is designed to be inserted inside. Here, the pusher 325 is attached to the outer peripheral surface of the winding bar 11, and its outer diameter isPropeller shaftIt is formed smaller than the inner diameter.
  Further, the front end (the left end in FIGS. 5 and 9) of the pusher 325 is in contact with the cardboard wound up by the take-up bar 11, and the rear end is connected via an arm 328, a pin 329 and the like (see FIG. 9). It is attached to the movable rail 323.
[0043]
  Accordingly, when the motor 321 of the cardboard transport mechanism 32 is operated, the pusher 325 also moves together with the movable rail 323. And the cardboard is graduallyPropeller shaftOnce the last set of hand members 311 and 312 is opened, the end of the pusher 325 pushes the rear end of the cardboard until the end.Propeller shaftCardboard is inserted inside.
[0044]
  The pusher 325 is supplied.Propeller shaftA plurality of pushers having different diameters are prepared in accordance with the diameters of the pins 329 and are configured to be exchangeable by removing the pins 329. This is because all of the pushersPropeller shaftThe smallest diameter is required to make it insertable insidePropeller shaftIt is necessary to match the outer diameter of the pusher with this, but when configured in this way, the diameter is large.Propeller shaftThen, the pusher does not come into contact with the cardboard.Propeller shaftThis is because there is a possibility that it cannot be inserted inside.
[0045]
  By the way, when inserting cardboard,Propeller shaftUp to the insertion work position shown in FIG. 1 and FIG.Propeller shaftHowever, in addition to the above-described axis alignment mechanism 22,Propeller shaftA rotation mechanism (not shown) is provided for rotating the.
  This rotating mechanism is used when inserting cardboard.Propeller shaftIs rotated in the direction opposite to the direction in which the cardboard is wound (the direction of rotation of the winding bar), so that even if the cardboard is about to spread when the cardboard is inserted, the cardboard can be inserted with as little resistance as possible. ing.
[0046]
  According to one embodiment of the present inventionPropeller shaftSince the inner cardboard incorporating device is configured as described above,Propeller shaftThe method for incorporating the inner cardboard will be described as follows.
  First, rectangular thick paper is cut from the roll-shaped thick paper, and the rectangular thick paper is wound a predetermined number of times while being pressed against the surface of the winding bar 11 (winding operation). Next, the wound cardboard is sandwiched and gripped from the outer periphery, and the pressing of the cardboard is released. The gripped cardboard was placed on the central axis of the winding bar 11Propeller shaftInsert the slide into the inside (insertion work).
[0047]
  Explaining in more detail about this integration method,Propeller shaftIs started, the first cutter 14 and the second cutter 15 are activated at a predetermined timing,Propeller shaftThe roll-shaped cardboard is cut into a rectangle according to the length and inner diameter of the paper.
  The thick paper is then inserted into the slit 111 of the winding bar 11 by the thick paper supply mechanism 13. That is, when the thick paper is conveyed to the front of the roller 131 of the thick paper supply mechanism 13, insertion of the thick paper is detected by a photoelectric switch or the like, and the motor 132 is driven. The rotational driving force of the motor 132 is transmitted to the roller 131 via the belt 134, whereby the cardboard is fed by the roller 131 while being guided by the guide 133 and is fed toward the winding bar 11. When the motor 132 rotates by a predetermined number of rotations, the edge of the cardboard is inserted into the slit 111 of the winding bar 11 and the operation of the motor 132 is stopped.
[0048]
  When thick paper is inserted into the slit 111, the actuator 121 of the spread prevention mechanism 12 then extends toward the winding bar 11, and the pressing member 122 provided at the tip of the actuator 121 is close to the outer peripheral surface of the winding bar 11. (Or contact).
  When the actuator 121 is extended, the winding motor 112 below the winding bar 11 is operated to wind the cardboard around the outer periphery of the winding bar 11. Further, when the winding bar 11 is rotated, the pressing member 122 presses the cardboard so as to be along the outer peripheral surface of the coiling bar 11, so that the cardboard is wound without forming a gap with the winding bar 11.
[0049]
  Also, almost at the same time as this winding work,Propeller shaftIs conveyed to the insertion work position by the conveyor 4 and the conveyor loader 21. At this insertion work position, the winding bar 11 isPropeller shaftAxis alignment is performed. That is,Propeller shaftIs transferred to the insertion work position, the actuator 221 expands as shown in FIG.Propeller shaftIs lifted by rollers 222 and 223. ThisPropeller shaftCenter height ofPropeller shaftRegardless of the diameter, it is adjusted to an intermediate position between the upper and lower rollers 222 and 223. The intermediate position between the upper and lower rollers 222 and 223 is set in advance so as to coincide with the center axis position of the winding bar 11, and the actuator 221 only extends.Propeller shaftAnd the central axis of the winding bar 11 coincide with each other.
[0050]
  When the center alignment is performed by the axis alignment mechanism 22 in this way,Propeller shaftAn insertion operation for inserting a cardboard is performed.
  In this case, the cardboard is first held by the hand mechanism 31 of the insertion mechanism 3. In other words, the semicircular hand members 311 and 312 that have been waiting above the winding bar 11 operate to hold the winding bar 11, and when the winding bar 11 is held by these hand members 311 and 312, the spreading is performed. The actuator 121 of the prevention mechanism 12 is degenerated. As a result, the thick paper spreads outward due to the elasticity of the thick paper, and the thick paper comes into close contact with the rubber sheet 314 inside each hand member 311, 312. At substantially the same time, the actuator 115 at the tip of the winding bar 11 is retracted, and the tip of the winding bar 11 is released.
[0051]
  In such a state, by operating the motor 321 of the cardboard transport mechanism 32, the movable rail 323 moves along the guide 324 via the rack and pinion mechanism 322, and the cardboard gripped by the hand mechanism 31. Comes out of the winding bar 11 and the cardboardPropeller shaftConveyed to the side.
  Thereafter, the thick paper transport mechanism 32 removes the leading edge of the thick paper.Propeller shaftWhen inserted, the hand members 311 and 312 open sequentially from the tip side.Propeller shaftThe cardboard is inserted while avoiding the interference.
[0052]
  At this time, a rotation mechanism (not shown)Propeller shaftIs rotated in the opposite direction to the winding direction of the thick paper (the rotation direction of the winding bar), thereby reducing the resistance when the thick paper is about to spread when the thick paper is inserted.
  When the last pair of hand members 311 and 312 (that is, the right end in FIG. 4) is opened, the cardboard is pushed in by the pusher 325 that is in contact with the trailing edge of the cardboard, and it is ensured to the end.Propeller shaftCardboard is inserted inside.
[0053]
  After the cardboard is inserted as described above, the transport loader 21 thereafterPropeller shaftIs transported to the next process and newPropeller shaftIs supplied and the above-described operation is repeatedly executed.
  Thus, according to the position embodiment of the present invention.Propeller shaftAccording to the inner cardboard incorporating device, the winding mechanism 1 andPropeller shaftThe work of winding cardboard by the transport mechanism 2 and the insertion mechanism 3Propeller shaftSince the inserting operation into the inside is continuously and automatically performed, the burden on the operator can be reduced by the automation of the operation. In addition, there is an advantage that the number of man-hours required for the work can be reduced, and there is an advantage that variations in quality can be eliminated. Further, since the winding bar 11 is formed with the slit 111 into which the end of the thick paper is inserted along the axial direction thereof, the thick paper can be reliably wound around the winding bar 11.
[0054]
