The specific embodiment

Fig. 1 is the schematic side view of folding machine of the present invention.The one material band 01 such as paper tape 01 grade from not shown printing equipment passes the superstructure 03 that chill roll frame 02 arrives folding machine.Described superstructure 03 comprises: longitudinal cutting device 04 is used for the paper tape 01 of input is cut into a plurality of branch paper tapes arranged side by side; Commutation cover plate 06, paper tape 01 and other sometimes not shown paper tape divide the direction of being with that is provided with to be adjusted respectively on described commutation cover plate 06, and be perpendicular to page orientation (in Fig. 1 from left to right) displacement and/or revolution, stacked mutually then.The path of paper tape 01 is from commutation cover plate 06, strip length compensated and 07 pair of compensating roller being used for traction is controlled extends to folding set square 08 through being used for.

Folding set square 08 and compensating roller 07, repeat to illustrate with the position of two mutual dislocation in Fig. 1 for this situation is illustrated being maintained at movably on the side direction of Fig. 1 on the common frame.

Paper tape 01 begins to be passed down through infeed set-up 24 and cross break device from the outlet of folding set square 08, in view of the cross break device known, so its structure is repeated no more at this.As among Fig. 1 with shown in the thick black line, guide rail 09 extends along the paper feed path of paper tape 01.The inlet that enters chill roll frame 02 from guide rail 09 begins until the guide rail 09 of the lower end of folding set square 08 as seen from the figure; Preferred guide rail 09 extends to folding set square 08 incessantly always or surpasses folding set square 08 from the roll changer of unshowned printing equipment among Fig. 1 that is arranged on the folding machine front.

As shown in Figure 2, guide rail 09 has the cross section of U-shaped or C shape, and Chain element 51 is directed in the groove 23 of guide rail 09 respectively, particularly is directed in the cannelure 23.Chain link 51 is by joints 52 monobasic that replaces or two yuan; 53 constitute described joint 52; At least one joint in 53 supports the arm 19 that stretches out in groove 23.Two adjacent joints 53 support an arm 19 jointly among Fig. 2.Also chain link 51 and arm 19 are called

keeper

51,19 hereinafter.Be provided with a hook spare in the end of arm 19, so that the leading end 54 of the new paper tape that remains to be drawn 01 or the traction end that is connected with leading end 54 are fixed by means of band around grab.

The chain link 52 of monobasic itself has elasticity, for example be made into integration by elastomeric material, or have the middleware that (unshowned in Fig. 2) is made of spring steel etc., and therefore Chain element 51 can realize around the axle longitudinally that is parallel to guide rail 09 reverse and center on perpendicular to the plane of paper tape 01 spool deflection.

On guide rail 09, the motor (not shown) is installed with the orderly spacing of standard, described motor supports sprocket wheel respectively, described sprocket wheel passes through in the groove 23 of the slit of guide rail 09 side embedding guide rail 09 and is engaged in case of necessity between the

chain link

52,53 that is positioned at the locational Chain element 51 of sprocket wheel.The length that Chain element 51 is selected for use is slightly larger than the spacings of two sprocket wheels that successively are provided with along guide rail 09, thereby guarantees that Chain element 51 when guide rail 09 moves, has at least one sprocket wheel and Chain element 51 to mesh and described Chain element 51 is driven all the time.The leading end 54 of paper tape 01 is separately fixed on the arm 19 that Chain element 51 stretches out in the groove 23, and then Chain element 51 is moved along guide rail 09, so that paper tape 01 is drawn.

Fig. 3 is the zoomed-in view of folding set square 08 shown in Figure 1 and surrounding member thereof.Chain-dotted line among Fig. 3 is represented guide rail 09 or by the stretching, extension of the paper tape 01 of guide rail 09 traction.With two other rail guide piece 12 shown in dotted line or the uniform fine rule; 13 converge at guide rail 09 and to converge roller 11.At rail guide piece 12; 13 with the point that converges of guide rail 09 before not far position, at each rail guide piece 12; 13 are provided with the sensor 14 of the existence that is used to detect trailed paper tape 01, for example photoelectric tube 14 and the bonding preparation device 16 that is used for adhesive-applying 15.The design of bonding preparation device 16 should be with on the boot segment of liquid adhesive substance band attached to paper tape 01, paper tape 01 along rail guide piece 12 or 13 from bonding preparation device 16 bypass mistakes; For example in EP0477769B1 the organization plan to this bonding preparation device describe.It is also conceivable that in addition and adopt the splicing tape supply as bonding preparation device 16, in case photoelectric tube 14 illustrates entering of paper tape 01, the splicing tape supply will move on the bandwidth direction of paper tape 01, so as with the two-sided tape roll extrusion on paper tape 01.

Bonding preparation device 16 also can be made of a plurality of bonding agent nozzles, described nozzle is distributed on the bandwidth of paper tape 01 and to described nozzle and is equipped with a photoelectric tube 14 respectively, when being conducted through one of them bonding agent nozzle, will impel the bonding agent nozzle that the certain amount of bonding agent is sprayed on the paper tape 01 with convenient paper tape 01.Scope in Fig. 5 above the folding set square 08 is clearly shown that this especially.

Point last one was to along guide rail 09 between the selection that the paper tape that is directed to along rail guide piece 12 01 is arrived the time point that converges roller 11 should make at this moment, the Chain element 51 that 13 paper tapes that move 01 draw is just in time by converging roller 11, thereby makes Chain element 51 from rail guide piece 12 be switched on the guide rail 09 and continued to carry on guide rail 09.

In case described Chain element 51 is fully by converging roller 11, can be in the corresponding way along

rail guide piece

09,13 then to another paper tape channeling conduct, and it be bonded in move through on the paper tape 01 that converges roller 11.

The band bundle that adopts this mode to obtain passes cutting means 17, for example pass set square cutting means 17 with rotating knife and edge bearing roller, described set square cutting means 17 is used for passing at all the paper tape (its end is mutually bonding with another trailed paper tape) of set square cutting means 17, promptly particularly by rail guide piece 12; The arm 19 that no longer need this moment on 13 paper tapes of carrying excises with the joint of paper tape end.

Band bundle is tilted to down and is shrunk on the most advanced and sophisticated surface being commutated again on the set square input roller 18 and arrive folding set square 08.When the band bundle drew on folding set square 08 side rib, the orientation of band bundle changed; Become the orientation that is basically parallel to Fig. 3 midplane from the orientation that is basically perpendicular to Fig. 3 midplane at set square input roller 18 upstream sides.In order still to lead to paper tape except carrying out directional transforms, described guide rail 09 reverses 90 ° in the section 21 of folding deflector roll 18 back, in order to be clearly shown that, has only intercepted part guide rails 09 in the vertical in Fig. 4.Guide rail 09 reverses 90 ° on the section 21 of set square input roller 18 back.For ease of understanding, a part of set square input roller 18 and a part of folding set square 08 only are shown among the figure to orientation; The axle of set square input roller 18 is parallel to the plane orientation of Fig. 4.By after the set square input roller 1818, still towards set square input roller 18, and the arm 19 of keeper protrudes out to set square input roller 18 in groove 23 during groove 23 beginnings of guide rail 09.Groove 23 in twist section 21 Fig. 4 changes forward gradually, thereby can see the pin and the chain link 52 of the chain in groove 23; 53.By twist section 21 time, the orientation of Chain element 51 is rotated 90 °, and is given prominence to forward perpendicular to the plane of Fig. 4 by the arm 19 that Chain element 51 supports.Be to be noted that three arms 19 shown in Figure 4 are not three arms 19 of same Chain element 51, but the arm 19 that illustrates is the different stages of moving along guide rail 09.Even realized paper tape 01 accurate guiding to it after by folding set square 08 by reversing.

Fig. 5 is clearly shown that the stretching, extension of the continuation of guide rail 09, and Fig. 5 illustrates the structure identical with Fig. 3 with the visual angle of half-twist.Tip below folding set square 08 begins guide rail 09 stretches vertically downward and passes between conveying roller, and described conveying roller is adapted to tripping when the traction paper tape, thereby can not hinder the passing through of arm 19 of fixing paper tape end.Guide rail 09 should make paper tape 01 be admitted to cutting in the slit of described infeed set-up 24 by the moving of slit that cut of infeed set-up 24.Infeed set-up 24 comprises cylinder 26 and cylinder 27, for example knife cylinder 26 and grippers cylinder 27 and/or folding blade cylinder 27, cylinder 27 is provided with the edge bearing that not shown hard rubber material is made, and described edge bearing cooperates with the cutter of knife cylinder 26 when infeed set-up 24 work.Cylinder 27 is folding blade cylinder 27 preferably, and has such as grippers or choose the keeper of paper pin.When paper tape 01 is drawn, the cylinder 26 of infeed set-up 24; 27 are in the state shown in the figure, and wherein the cutter 28 of knife cylinder 26 is aimed at the parallel lines of guide rail 09 substantially, thereby at cylinder 26; Leave the slit between 27, paper tape 01 passes described slit and is pulled.

Figure 12 illustrates the useful form of implementation of Chain element 51.Chain element 51 has the wheel that is supported on respectively on the pin 22, and wherein pin 22 is connected plate and links together spaced reciprocally.In order to make Chain element 51 not only around the swing of the longitudinal axis of pin 22, the hole in the connecting plate for example is slightly larger than the diameter of pin 22, thereby Chain element 51 can be perpendicular to the moving direction of pin 22 or crooked on the y direction of pin 22.Therefore the maximum deflection radius R 51 under case of bending is 1000mm, or preferably less than 600mm, particularly preferably is less than 500mm.

Pin 22 can have different diameters on it is vertical, particularly can be spherical.

Shown in Figure 4 below folding set square 08 the tip and two convergent points 29 between the inlet of infeed set-up 24; 31, at described convergent point 29; Another rail guide piece 32 is arranged respectively on 31; 33 meet with guide rail 09.Described rail guide piece 32; 33 are used for the band bundle channeling conduct to other, and these band bundles are for example by other not shown folding set square of folding machine.For with the described band bundle that is directed attached on the paper tape that is directed on the guide rail 09, be rail guide piece 32; 33 also are equipped with photoelectric tube 14 and bonding preparation device 16 respectively.

The separator 30 identical with not far position one its 26S Proteasome Structure and Function in back and set square separator 17 before infeed set-up 24, for example folding separator 30 is arranged on the guide rail 09.The folding separator 30 of front is used for along rail guide piece 32; The 33 band Shu Yuqi keepers of carrying are separated; The paper tape 01 at tip that the formation that the folding separator 30 of back is used at first will being pulled into enters the band bundle of horizontal cutting means separates with its keeper.

When all paper tapes 01 are pulled through infeed set-up 24, just can start infeed set-up 24.The end of all paper tapes 01 of trailed band bundle is cut through cutting for the first time.

After all keepers are separated by corresponding paper tape 01, described keeper is begun again along guide rail 09 or rail guide piece 12 at the latest; 13; 32; 33 are returned and are transported to its corresponding original position.Be transported to each original position for keeper is accurately returned, be provided with railway switch 34 respectively, the position of described railway switch 34 is controlled automatically, so that each keeper returned the original position that is transported to its distribution at the convergent point place.

Fig. 6 shows the structural design of folding machine with the visual angle that is similar to Fig. 4, and described folding machine has two folding set squares 08 arranged side by side, and described folding set square is used for the paper tapes 01 of four seal page widths of wide paper tape 01 are processed.In described design, be respectively each folding set square 08 oneself a guide rail 09 is set, 09 pair of paper tape of described guide rail is guided through infeed set-up 24.Say in principle, also two guide rails 09 can be converged before the path that passes infeed set-up 24 mutually; Certain this parallel conductive to the advantage of guide rail 09 be, there are two keepers can pass through infeed set-up 24 simultaneously respectively, thereby the time less that the traction of paper tape 01 is needed, and obviously reduced keeper at all paper tapes 01 and must draw total paper amount of passing through before by infeed set-up 24.

Fig. 7 and 11 illustrates guide rail 09 another design in the stretching, extension of the inlet of infeed set-up 24.Inlet front at infeed set-up 24 is provided with cutting means 36, is used for cutting edge to being pulled the band Shu Jinhang that passes through.Guide rail 09 directly passes cutting means 36 in vertical direction above the wedge shape inlet of infeed set-up 24.Below cutting means 36, guide rail 09 has bending section 37, and described bending section stretches upwards to separator 39 at the upper side of guide plate 38, and wherein said separator 39 is used for each end Duan Yuqi keeper by its paper tape 01 is separated.The band bundle that is not directed in separator 39 back freely falls and is disallowable from folding machine; Keeper is continued transported to one or more storage devices 41, described storage device 41 as shown be helical coil around guide rail.Another kind of structure of saving the storage device 41 in space is the guide rail of zigzag shape bending, and it preferably has and cylinder 26; 27 the parallel longitudinal axis of axle.

In this design, all paper tapes 01 be pulled finish before, the cylinder 26 of infeed set-up 24; 27 can Phase synchronization ground rotate with the carry-over pinch rolls of folding machine or the printer part that is positioned at its front.In case this situation occurs, cutting means 36 is just once cut edge to band Shu Jinhang.Simultaneously, the railway switch 42 that is provided with in the wedge shape porch of infeed set-up 24 from shown in traction pass position transfer to position shown in the dotted line so that newly-generated band bundle leading edge is embedded in the infeed set-up 24 reliably.This is because the rotary speed that infeed set-up can adapt with the transporting velocity with the band bundle when band Shu Jinhang is cut moves, thereby shortened the needed time of realization stable printing condition and therefore reduced the maculature amount that when printing machine is started shooting, produces.

In order further to reduce the maculature amount, can carry-over pinch rolls on be provided for detecting the sensor such as photoelectric tube 14 of the existence of paper tape 01, wherein to pass described carry-over pinch rolls by roll changer to the path of infeed set-up 24 right for paper tape 01, and carry-over pinch rolls are to being adapted to tripping when paper tape 01 is drawn, to pass carry-over pinch rolls right in case described photoelectric tube 14 identifies paper tape 01, to impel carry-over pinch rolls to quilt combined pressure and driving mutually, so that on relevant paper tape 01, produce predetermined traction stresses.Therefore paper tape 01 being carried out can begin to make traction stresses and the desired value of stable printing operation to adapt between period of traction, also shortened thus and realized the described needed time of stable condition.

Adding man-hour at the paper tape 01 that adopts folding machine to different in width, is that described paper tape 01 accurately passes infeed set-up 24 and cross break device following closely in the centre for trouble-free operation the important point.Need to carry out for this reason in conjunction with Fig. 1 described with cylinder 26; 27 axle or with infeed set-up 24 cut moving of double spread set square 08 on the parallel direction of direction.Fig. 3 and 8 clearly shows this point.The position that is applicable to the folding set square 08 of paper tape 01 shown in Figure 3 with maximum machining width in folding machine.If under the situation of the identical position of folding set square 08 to width narrow the paper tape of 2a process, preferably respectively the left side edge of infeed set-up 24 reserve width be a a blank need not, and carry out in the right side edge of infeed set-up 24 that situation with the wideest paper tape 01 is identical carries out vertical folding.For this narrow paper tape 01 is correctly imported in the infeed set-up 24, need double spread set square 08 as shown in Figure 8, converge roller 11, rail guide piece 12; 13 and the frame that supports of compensating roller 07 be moved to the left the distance of a/2.For realizing this point, guide rail 09 pull at commutation lid 06 and compensating roller 07 between scope 43 in (see figure 1) can telescopically be drawn out or can change length in other suitable mode, and guide rail 09 is respectively in the scope 44 of the tip or the bottom of folding set square 08; 46 is interior with movable joint section 44; 46 form has flexible structure, so that can both realize keeper passing smoothly on folding machine on each position that folding set square 08 is got, arrives storage device 41 always.

Fig. 9 and 10 illustrates the decision design of the guide rail 09 of this bending.Wherein Fig. 9 is the vertical view of bending

section

44 or 46, and Figure 10 illustrates the cutaway view on the online X-X height of guide rail of Fig. 9.Tangent plane passes any in a plurality of otch 47, and described otch 47 difference in the

scope

44 or 46 of bending is alternately formed by the not ipsilateral of guide rail 09, and the sidewall 48 of the saturating incisal guide rail 09 of otch 47 difference.The sidewall 48 that still exists on otch 47 height is not significantly than being easy to bending by the guide rail 09 of otch, and described sidewall 48 at first can realize the controlled bending of guide rail 09 on a plane, can not occur again reversing simultaneously.

Fig. 8 illustrates the configuration of guide rail 09 with dotted outline, and wherein being positioned at can crooked scope 44; The guide rail section of 46 tops is crooked left.Otch 47 alternately narrows down according to orientation or broadens.For this principle is illustrated visually, the width and the degree of crook of otch 47 is shown in the mode of exaggeration in the drawings; In fact the width of otch 47 and deformation extent thereof do not reach the degree that chain link passes groove 23 smoothly that influences.Because the crooked free degree of necessity of guide rail 09 is not more than the several years and when bending the quantity of otch many more, then the degree launched of each otch is just more little, thereby can satisfy this requirement without a doubt.

In a kind of useful form of implementation, the interval X of guide rail 09 and paper tape 01 is both at distraction procedure, also at whole hinge structure, promptly at least from carrying set square folding roller 18 without the paper tape 01 of folding, promptly at least from carrying to not begun through folding set square 08 path, until the tip of folding set square by the set square folding roller 18 of the paper tape 01 of folding.

The preferred employing do not carried out attaching troops to a unit of presswork this moment and realized distraction procedure to the printing equipment in the paper feed path of paper tape.
