Then, with reference to Fig. 1～Fig. 4, for the effect of the sticker again 1 of the present embodiment being formed by structure as described above, be divided into (1) for the processing of supply tray, (2) for the processing that pallet reversed again paste, (3) for sheet cutting these three situations of processing of receiving are described.
[1-2-1. is for the processing of supply tray]
Again sticker 1 is for supply tray, first, charging tray 2 moves in the vertical direction by lift 3, and desirable supply tray K is positioned at as the plane identical from the lift-launch face 511 drain position and absorption hand 51 pusher mechanism 4 or pallet reversing device 5 of charging tray 2 and stop.
The discharge of pusher mechanism 4 is inserted press section with respect to charging tray 2 under this state in the horizontal direction with pusher 41, and supply tray K is discharged to absorption hand 51 sides from charging tray 2.The supply tray K discharging from charging tray 2 is sent to the lift-launch face of pallet reversing device 5, is adsorbed and remains on absorption hand 51.By such processing, supply tray K is supplied with to pallet reversing device 5 from charging tray 2.
[1-2-2. is for making the pallet processing of again pasting of reversing]
Again sticker 1 is as for making the pallet processing of again pasting of reversing, first, by absorption hand 51 adsorbed in the pallet reversing device 5 of supply tray K, reverse process before, by be arranged on pallet reversing device 5 supply tray K receiving position directly over surface inspection camera 141 carry out visual examination to being mounted in the element surface of pasting on the first sheet material S1 on supply tray K.
In this visual examination, by near the RFID recognizer 15 being arranged on the receiving position of supply tray K of pallet reversing device 5, read the identifying information about being attached to classification stored in the IC tag on supply tray K, it is inputted to the control part of bar code label printer 9 described later and sheet material classification lift 12, in bar code label printer 9, prepare the bar code of the presentation class information on sheet material of sticking together, and at sheet material classification lift 12, determine in the time receiving the second sheet material S2 to accepting rack 13, this second sheet material S2 is accommodated in to which position of multistage accepting rack 13.
Then, pallet reversing device 5, by the effect of reverse motor 52, makes to adsorb hand 51 and reverses centered by rotating shaft O.Now, rotate by feed rolls 72, supply with the second sheet material S2 from the sheet material cylinder 71 of the bottom that is arranged on pallet reversing device 5.This second sheet material S2 is emitted by volume in substantially vertical direction from sheet material cylinder 71, and by roller 711 and 712 location, sheet material is towards being converted in the horizontal direction.In addition, peel off sticking on the protection sheet material sticking together face that sticks together sheet material from roller 711, the protection sheet material takers-in 8 that this protection sheet material is arranged on bottom batches.By this roller 712 changed in the horizontal direction towards stick together sheet material by the rotary actuation of feed rolls 72, make to stick together towards on be transported, by the rotation control of this feed rolls 72, stop at assigned position.
Under such state, reverse motor 52 makes supply tray K reversion, reverse motor 52 makes the lift-launch face 511 that adsorbs hand 51 taking its axial region 512 as rotating shaft Rotate 180 degree, maintain by be maintained at the first sheet material S1 on supply tray K on the second sheet material S2 butt horizontal level.
Then, paste adjusting mechanism 54 and start the state shown in this figure (a) from the state of Fig. 4 (b), below the second sheet material S2, side is by push jack material the face forming with the equal area of pasted area, accordingly, the first sheet material S1 and the second sheet material S2 that are maintained at the supply tray K on absorption hand 51 are sandwiched.
Specifically, paste the lifting of adjusting mechanism 54 and rotate with motor 547, accompany with it, lifting is rotated with cam 546, accordingly, bears platform 545 and rises.So, the supporter 544 being attached thereto rises, and matches with it, and silica gel sheet material 541, board mounting 542 also rise, and presses the second sheet material S2 by this silica gel sheet material 541 from below.Now, first, eccentric degree according to lifting with cam 546, the rising degree of platform 545, supporter 544, silica gel sheet material 541 and board mounting 542 is born in adjustment, adjust the amount of pushing from below with respect to the second sheet material S2, the second, adjust spring 543 by the plus-pressure by the bottom that is arranged on board mounting 542, silica gel sheet material 541 and board mounting 542 are suppressed to the second sheet material S2 direction, adjust the butt pressure with respect to the second sheet material S2 of silica gel sheet material 541.
Now, for example use as gel sheet the sheet material that adhesion is 2～3N/20mm as the first sheet material S1, the sheet material that the second sheet material S2 is 5～10N/20mm as the UV sheet material use adhesion of ultraviolet pre-irradiation like this, use the sheet material that sticks together a little less than adhesion as the first sheet material S1 that pastes main body, as the second sheet material S2 of the body that is stuck use adhesion strong stick together sheet material, accordingly, absorption hand 51 by structure as described above reverses, apply modest pressure and push the first sheet material S1 to the second sheet material S2, carry out the stickup again of element.
If as described above, element finishes to the sticking operation again of the second sheet material S2 from the first sheet material S1, adsorbs hand 51 again by reverse motor 52 derotation turnbacks, returns to the original receiving position that has received supply tray K from charging tray 2.
In the position of such absorption hand 51, wiper mechanism 6 plays a role.That is, roller supporter 62 and the cleaning roller 61 that is supported on its front end by lift cylinders 631 from primary position A upwards position B move, then, use cylinder 632 to the first sheet material S1 side shifting by slip.Now, the pulling by this slip with cylinder 632, sticks together band and is drawn out from sticking together band roller 64.And, by lift cylinders 631 from position B to moving with the upper/lower positions of primary position A equal height, be arranged on behind the end of the first sheet material S1, by the effect of slip cylinder 632, one side moves on the first sheet material S1, one side is cleaned the first sheet material S1.Cleaning roller 61 now the pushing force of the first sheet material S1 is adjusted with cylinder 632 by lifting.
As mentioned above, if cleaning roller 61 finishes to move on the first sheet material S1, use cylinder 631 by lifting and slide with the effect of cylinder 632, supporter 62 returns to primary position A, still, now, conventionally sticks together belt sag.Therefore, in the present embodiment, rotate and prevent such relaxing by utilizing motor to make and having cleaned with roller 65.This moment of torsion that batches the motor of use is suppressed to and is low to moderate the lax degree of eliminating.In addition, ratchet 651 is set having cleaned band roller 65, by this ratchet 651, in the time cleaning, in the time that cleaning roller 61 and roller supporter 62 move because of the effect of slip cylinder 632, band is sticked together in pulling, accordingly, do not exist use stick together band because of derotation then from having cleaned the situation of having been emitted by volume with roller 65.In addition, if excessively strong because batch the moment of torsion of motor of use, be not subject to the impact of the action of cylinder 63, will stick together band and all batch, so, be necessary to carry out the adjustment of appropriate moment of torsion.
If clean finishes, adsorb hand 51 and empty supply tray K to charging tray 2 returned by above-mentioned returning with pusher 42 in this position of having returned.By such absorption hand 51 is reversed, again paste, finish a processing, absorption hand 51 receives the supply tray K from above-mentioned charging tray 2 again, reverses by reverse motor 52, again pastes.
Now, displacement mechanism 53 slides mobile with respect to the direct of travel of the second sheet material S2 of absorption hand 51 to Y direction in the figure as Width., absorption hand 51 carries out following a series of processing repeatedly by the control of displacement mechanism 53 and feed rolls 72, described a series of being treated to: if the stickup again of the element at a position finishes, one side moves in the Y direction of the Width as the second sheet material S2, one side is on the second sheet material S2, the receiving position of supply tray K and again paste position spend toward double action 180 at 1～4 position, one side is pasted element again, after this, by feed rolls 72 described later by the second about sheet material S2 feeding 5cm, absorption hand 51 slides mobile again, element is pasted at 5～8 positions to the second sheet material S2 again, again by the second sheet material S2 feeding 5cm, element is pasted at 9～12 positions to the second sheet material S2 again, and then, by the second sheet material S2 feeding 5cm, carry out again pasting so a series of processing to 13～16 positions of the second sheet material S2.
Here, if because pallet reversing device 5 Rotate 180 degree, return to original position, the element that the first sheet material S1 from supply tray K has been pasted again becomes at the second sheet material S2 that to make its inside side be the state being stuck, so, by be arranged on pallet reversing device 5 paste position again directly over the inside check that camera 142 carries out the visual examination of element the inside.
If a series of gluing treatment again as described above finishes, feed rolls 72 is rotated driving, makes the second sheet material S2 side shifting downstream.Now, in the bar code label printer 9 under being arranged on feed rolls 72, with respect to the second sheet material S2 being pasted again, paste the bar code of making according to the Classification and Identification information of inputting from RFID recognizer 15.Meanwhile, be accompanied by the rotary actuation of this feed rolls 72, from protection sheet material cylinder 10, protection sheet material volume emitted, with respect to the component affixing protection sheet material on the second sheet material S2 that is secured at of specified quantity.That is, with regard to this bar code label and protection sheet material, by sandwiching of feed rolls 72, paste bar code label in the inside of the second sheet material S2 side respectively simultaneously, paste protection sheet material on the surface of the second sheet material S2.
[1-2-3. for by sheet cutting the processing of receiving]
By the rotary actuation of feed rolls 72 as described above, by be secured at element on the second sheet material S2 downstream side transport, be transported between the maintaining roller 121 and 122 of sheet material classification lift 12.Now, in the maintaining roller 122 of accepting rack 13 that approaches downstream, if confirmed the arrival of the second sheet material S2 by the detection means such as transducer, camera, feed rolls 72 stops transporting.
If the maintaining roller 122 by sheet material classification lift 12 has kept the situation of the second sheet material S2 to be confirmed, feed rolls 72 stops the second transporting of sheet material S2, and the sheet material cutter 11 that is arranged on the upstream side compared with maintaining roller 121 cuts the second sheet material S2 in this position at Width (Y-direction in figure).
Sheet material classification lift 12, in order to keep cut the second square sheet material S2 of 20cm by the maintaining roller 121 and 112 that is arranged on front-end and back-end, inserts the second kept sheet material S2 the accepting rack 13 of regulation, and moves up and down by the effect of elevator mechanism.If sheet material classification lift 12 moves to the position of the accepting rack 13 of regulation, the maintaining roller 121 and 122 of sheet material classification lift 12 is rotated driving, and the second kept sheet material S2, to accepting rack 13 side feedings, is accommodated in the second sheet material S2 in accepting rack 13.After storage, sheet material classification lift 12 turn back to as original position, with feed rolls 72 upper and lower identical position in the vertical direction, wait for the arrival of the second sheet material S2 that the next one sent here.
[1-3. effect]
According to the sticker again 1 of present embodiment as described above, by carry out successively from multistage the charging tray of receiving the pallet that possesses the first sheet material that is pasted with the element that is classified differentiation to can the second sheet material of the size utilized in operation again paste element, the stickup again between sheet material of element based on automatic operation can be realized, high speed and the convenience processed can be sought to improve.In addition, compared with the stickup again of the element by manually carrying out etc., the mistake such as can prevent from batch sneaking into.
