Abstract

Buckles (b1 to b4) are each provided with a stopper (S1 to S4). A pair of uptake rollers (W, W1); (W, W2); (W2, W3); (W3, W4), to supply paper to the buckles, and a pair of discharge rollers (W, W2); (W2, W3); (W3; W4); (W4, W5), to fold the portion of the paper discharged outside the buckles, are disposed at each buckle inlet. The discharge roller for a previous buckle simultaneously functions as the uptake roller for the next buckle, and the paper is sequentially introduced into the buckles and folded into a bellows form. Stopper drive mechanisms (d1 to d4) are integrally controlled by a control unit (C). The control unit receives input for the value of the difference in length between the last folded piece and the remaining folded piece of a bellows-folded paper in which a folding error has occurred, divides the length difference by the number of buckles, and sends control instructions to slide the stoppers in the same direction as the buckle inlet (e) relative to the stopper drive mechanisms for the length obtained by division in order to make the length difference zero.

Detailed description of the invention

Below, with reference to accompanying drawing, preferred embodiment of the present invention is described.The enlarged drawing of Fig. 1 to be the figure of the brief configuration of the paper folding apparatus representing one embodiment of the invention, Fig. 2 be structure in the paper folding portion representing the paper folding apparatus shown in Fig. 1.

With reference to Fig. 1, paper folding apparatus of the present invention possesses from the sheet feed section A supplying paper using P with pile M successively, the paper folding portion B that will supply the paper using P that comes and paper supply direction from sheet feed section A and fold at a right angle.

Sheet feed section A has: the shelf 1 that is elevated of mounting pile M and can carrying out thereon; The load-transfer device 2 extended between shelf 1 and paper folding portion B; By the paper using feeder 3 that the paper using P of the upper with pile M be positioned on shelf 1 sends into successively on load-transfer device 2.In this embodiment, paper using feeder 3 is made up of the roller rotated by driving above the front end being configured in shelf 1.It should be noted that, in the drawings, 4 represent the idler rollers group of floating suppressing paper using P from load-transfer device 2.

Paper folding portion B has: the multiple folders imported successively by the paper using P supplied from load-transfer device 2 are four folder b1 ~ b4 in the present embodiment; Be configured to respectively to carry out along the importing direction of paper using P stopper S1 ~ S4 of sliding in four folder b1 ~ b4.In this case, in each folder b1 ~ b4, be provided with the guide rail in parallel therewith extending (not shown), stopper S1 ~ S4 can be slidably mounted on this guide rail.Further, abutted with stopper S1 ~ S4 by the front end importing to the paper using P in folder b1 ~ b4, thus this paper using P is navigated to the folding position pre-determined.

Paper folding portion B also has the stopper driver train d1 ~ d4 that stopper S1 ~ S4 is slided arranged respectively on folder b1 ~ b4.

With reference to Fig. 2, stopper driver train d1 ~ d4 comprises in the present embodiment: extend abreast with folder b1 ~ b4, pivotally can be bearing in the lead screw shaft 5 of the ball-screw on folder b1 ~ b4; Be arranged on folder b1 ~ b4, make the electrical motor 6 that lead screw shaft 5 rotates; Be arranged on upper and paired with the lead screw shaft 5 of the ball-screw nut of stopper S1 ~ S4 (not shown), stopper S1 ~ S4 screws togather with lead screw shaft 5 by nut.

Further, rotated to both forward and reverse directions by electrical motor 6, stopper S1 ~ S4 is to the direction displacement of the entrance e close to or away from relevant folder b1 ~ b4 thus.

It should be noted that, the structure of stopper driver train d1 ~ d4 is not limited to this embodiment, also ball-screw and motor combination can be replaced, and use such as open to be located between a pair pulley and with folder b1 ~ b4 endless belt extended abreast and the motor combination that a side of pulley is rotated, endless belt is fixed stopper S1 ~ S4.

Stopper driver train d1 ~ d4 is unified to control by control part C.

Near the entrance e of each folder b1 ~ b4, for paper using P is taken into roller W, W1 to being rotated by driving for a pair of being taken into of folder b1 ~ b4; W, W2; W2, W3; W3, W4 are arranged opposite, and, for distributing roller W, W2 of being rotated by driving for a pair of folding the part be exposed at outside this folder b1 ~ b4 in the paper using P imported in folder b1 ~ b4; W2, W3; W3, W4; W4, W5 are arranged opposite.

And, the distributing roller relevant to previous folder is taken into roller as relevant with next folder and play function simultaneously, paper using P is imported to multiple folder successively, this paper using P to be rolled over the mountain that the mode at a right angle with paper supply direction alternately carries out the number of times corresponding with the number of folder and paddy is rolled over, thus be folded into corrugated.

That is, the paper using P load-transfer device 2 of sheet feed section A transported is introduced between pair of rolls W and W1, and the front end of paper using P is directed in folder b1.When the front end of paper using P abuts with the stopper S1 of folder b1, paper using P bends near the entrance of folder b1, and this flexed portion is introduced between pair of rolls W2 and W, thus by folding to side for paper using P (first folds).

Folded paper using P then imports for front end with this folding line in folder b2.When the front end importing to the paper using P in folder b2 abuts with stopper S2, paper using P bends at the entrance of folder b2, this flexed portion is introduced between pair of rolls W2 and W3, thus paper using P is folded (the second folding Stacked) to side contrary before.

Below, similarly by pair of rolls W2 and W3, pair of rolls W3 and W4, folder b3, by paper using P to folding with side contrary before (the 3rd folds), then, by pair of rolls W3 and W4, pair of rolls W4 and W5, folder b4, by paper using P to folding with side contrary before (the 4th folds).Like this, be folded into undulatory paper using P to discharge from paper folding apparatus.

In paper folding apparatus of the present invention, as shown in Figure 3A, in order to obtain the paper using P being folded into corrugated (each tabs P1 ~ P5 has equal length) equably, the position of the stopper S1 ~ S4 of each folder b1 ~ b4 is preset (usually by control part C, for all folder b1 ~ b4, to set from the equidistant mode of folder entrance to stopper S1 ~ S4).

But, speed when paper using P abuts with stopper S1 ~ S4 by slightly different each stopper S1 ~ S4, and, the hardness of paper using P or degree of flexibility slightly different by each paper using.Therefore, sometimes as shown in fig. 3b, the last tabs P5 of the undulatory paper using P obtained is than remaining tabs P1 ~ P4 long (L1), or as shown in Figure 3 C, the last tabs P5 of the undulatory paper using P of acquisition is shorter than remaining tabs P1 ~ P4 (L2).

According to the present invention, when there occurs so folding mistake, first, the difference that there occurs the folding wrong last tabs P5 of undulatory paper using P and the length of remaining tabs P1 ~ P4 is measured by operator.

Then, control part C accepts the input of the measured value of the difference of described length, by the number (be in the present embodiment four) of the value of the difference of described length divided by folder b1 ~ b4, when last tabs P5 is longer than remaining tabs P1 ~ P4 (with reference to Fig. 3 B), stopper driver train d1 ~ d4 is sent respectively to stopper S1 ~ S4 of making to be correlated with and slide through the such control command of the value (L1/4) of the length of division arithmetic gained to the direction of the entrance away from relevant folder b1 ~ b4, to make the difference of described length for zero.On the other hand, at last tabs P5 than remaining tabs P1 ~ P4 in short-term (with reference to Fig. 3 C), control part C sends stopper S1 ~ S4 of making to be correlated with respectively and slides through the such control command of the value (L2/4) of the length of division arithmetic gained, to make the difference of described length for zero to the mode of the entrance close to relevant folder b1 ~ b4 to stopper driver train d1 ~ d4.

It should be noted that, control part C will number divided by folder of the measured value of difference of length of input time, when eliminating, based on the result of division arithmetic is rounded up, carry or cast out obtained value and control stopper driver train d1 ~ d4.

Control part C has touch panel display (not shown) in the present embodiment as input part, and Fig. 4 shows the picture of the setting value of the position for inputting stopper S1 ~ S4 shown in this touch panel display.

In the diagram, 7a represents the region of the setting value of the position of the stopper S1 of input first folder b1,7b represents the region of the setting value of the position of the stopper S2 of input second folder b2,7c represents the region of the setting value of the position of the stopper S3 of input the 3rd folder b3, and 7d represents the region of the setting value of the position of the stopper S4 of input the 4th folder b4.Further, set from the position of distance to this stopper S1 ~ S4 of the entrance of folder b1 ~ b4 as stopper S1 ~ S4.

In the diagram, identical setting value (165.0mm) is inputted for all folder b1 ~ b4.It should be noted that, the input of numerical value uses (not shown) numerical key and is located at the "+" button on right side of each region 7a ~ 7d and "-" button carries out.

After the input of setting value completes, start the action of paper folding apparatus.Further, in paper folding action, when there occurs folding mistake, the difference of the last tabs of undulatory paper using and the length of remaining tabs is measured by operator.

Then, the picture of touch panel display is switched, the input picture of display measured value as shown in Figure 5.In Figure 5,8 represent the region inputting measured value, when the last tabs of undulatory paper using is longer than remaining tabs, in this region 8, measured value (difference of length) is inputted as positive numerical value, at last tabs than remaining tabs in short-term, in this region 8, measured value (difference of length) is inputted as negative numerical value.

In Figure 5, due to folding mistake, last tabs 8mm longer than remaining tabs, thus, inputs the numerical value of+8.0mm in region 8.

Like this, the measured value of+8mm is inputted to control part C by touch panel display by operator.

After input measured value, the picture of touch panel display switches to the input picture of the setting value of the position of stopper again.Now, the result that control part C carries out division arithmetic gained is 8mm/4=2mm, therefore the setting value 165.0mm of the region 7a ~ 7d be pre-entered in the picture of touch panel display is modified to 167.0mm by control part C as shown in Figure 6 without exception, to make all stopper S1 ~ S4 to the direction displacement 2mm away from folder entrance.Meanwhile, send to each stopper driver train control command stopper being slided based on this correction from control part C.Thus, folding mistake can be eliminated.

Like this, according to the present invention, when there occurs folding mistake in the operation that paper using is folding in corrugated equably, value by means of only the difference by the last tabs of undulatory paper using and the length of remaining tabs inputs to control part, just automatically again can set the position of the stopper of each folder thus to eliminate this folding mistake, therefore, it is possible to the setting again of the position of stopper easily and when carrying out there occurs folding mistake at short notice.
