Fig. 3 has shown the lithography thin plate piling apparatus 50 (being designated hereinafter simply as " piling apparatus 50 ") according to this embodiment of the invention.This piling apparatus 50 is used to pile up many Zhang Pings version printed web of sending into continuously from belt transporter 42 ends, thereby this lithography thin plate 46 is aligned in predetermined accumulation position and is piled into multilayer.
A pair of back member 58 is arranged on the direction of transfer shown in Figure 2 downstream, edge of the accumulation platform 52 in the piling apparatus 50.Check plate 60 is arranged on each back member 58, in the face of being deposited in the front surface of the lithography thin plate 46 on the deposition surface 54.It is parallel that check plate 60 is configured to its Width direction of transfer of making peace greatly.As shown in Figure 2, the base portion of being made up of metal sheet or plastic flagstone 62 is arranged on the base end part of check plate, is positioned at the opposite sense of piling up platform 52.Be positioned at the padded coaming 64 that the front surface of the base portion 62 of piling up platform 52 1 sides is coated with liner shape.
As shown in Figure 2, cylinder 66 is arranged on the member 58 of back so that support arresting disc 60 and cushion the impact from lithography thin plate 46.Cylinder 66 is arranged on the downstream of arresting disc 60 along direction of transfer, to such an extent as to and through support be fixed to handle line 10 framework, floor or similar portions not relatively belt transporter 42 change positions concern.Cylinder 66 supports central siphon 68 slidably along direction of transfer.The front end of the central siphon 68 in the cylinder 66 is connected and is fixed to the base portion 62 of check plate 60.In addition, the coil spring 70 that is in compressive state is set at the outer circumferential sides of central siphon 68.This coil spring 70 is along pushing check plate 60 in the opposite direction with the sender.At this, cylinder 66 can be adjusted the position along direction of transfer.Therefore, arresting disc 60 is to adjust along the length of direction of transfer according to being deposited in the lithography thin plate of piling up on the platform 52 46 along the position of direction of transfer.
As shown in Figure 3, piling apparatus 50 is provided with side member 72, and this side member is arranged on two ends (left side and the right) outer side surface of piling up platform 52.Shown in Fig. 3 and 4, it is roughly the same that side member 72 is configured to the width of distance and lithographic plate printed web 46 between it.This side member 72 comprises and a pair ofly is used to limit lithography thin plate 46 at the lower side member 72b of the motion of Width with a pair ofly be arranged on this to the upper side member 72a on the lower side member 72b; Among the upper side member 72a each is provided with the part that can move along the sheet width direction, and is formed with on it and becomes the roughly slope shape surface 85 of V-arrangement against each other.As shown in Figure 4, the slope shape of upper side member 72a surface 85 is preferably relative horizontal surface with more than 25 ° and less than 65 ° angle tilt.
In addition, as shown in Figure 4, upper side member 72a and lower side member 72b are fixed to frame fixation member 74.This frame fixation member 74 can move up and down according to the angle of the lithography thin plate 46 that is admitted to from belt transporter 42.Cylinder 76 is connected to each upper side member 72a.Control convenience 110 moves through the sliding component 78 control upper side member 72a broad wayss that are arranged between upper side member 72a and the lower side member 72b.In addition, the chassis, for example frame material 84a and 84b are separately positioned on upper side member 72a and the lower side member 72b.Frame material 84a and 84b are formed by stainless plate, for example steel plate and other slab materials, and it is indeformable so that stand from the impact load of lithography thin plate 46 to have enough intensity.In addition, the position of upper side member 72a broad ways is adjustable.Before lithography thin plate 46 was admitted to belt transporter 42, corresponding to the width of lithography thin plate 46, side member 72 broad wayss were adjusted to certain position.This side member 72 is configured to: its Width be deposited in the Width (direction of arrow W) of piling up the lithography thin plate 46 on the platform 52 and be complementary, its length direction roughly is complementary with the direction of transfer of lithographic plate printed web 46.This has symmetrical structure to side member 72, and broad ways shape respect to one another.
In addition, shown in Fig. 3 and 4, a plurality of claw components 47 that can give prominence in the horizontal direction and regain are arranged on a pair of lower side member 72a of deposition surface 54 tops relative to one another.This is used for outstanding and regain claw component 47 ground and give prominence to/and retraction mechanism do not show, still, and distance, the inside of lower side member 72b is hollowed out, and the hole that is used to give prominence to is formed on lower side member 72b and frame material 84b.So piston cylinder, stepping motor, cam mechanism and allied equipment can be arranged on the inner conduct of lower side member 72b of this hollow and give prominence to/retraction mechanism.Outstanding and withdrawal time time of claw component 47 can be controlled through using above-mentioned control convenience 110 to control outstanding/retraction mechanism.The outstanding time of claw component 47 is preferably before lithography thin plate 46 is about to fall from slope shape respect to one another surface 85, thereby receives the lithography thin plate 46 that this falls.In addition, the preferred withdrawal time of claw component 47 is not instantaneous after claw component 47 receives lithography thin plate 46, but after the lithography thin plate 46 that claw component 47 receives stops vibration and stop motion.Then, this claw component 47 is retracted, thereby lithography thin plate 46 drops on the deposition surface 54 once more.The time that the lithography thin plate 46 that is provided with for control convenience 110 stops to vibrate can obtain through test or similar approach in advance.
According to present embodiment, as shown in Figure 4, the along continuous straight runs compartment of terrain is provided with three (6 altogether) claw components on each lower side member 72b, but this claw component ground quantity can be two or more.Should be noted that lithography thin plate 46 between a pair of slope shape surface that is placed on upper side member 72a respect to one another falls to 54 last times of deposition surface, the quantity of this claw component 47 is enough to be used for firmly and temporarily receiving this lithography thin plate 46.In addition, if begin to fall from being placed on lithography thin plate 46 between a pair of slope shape surface that to receive time of this lithography thin plate 46 up to this claw component 47 oversize, lithography thin plate 46 maybe the medium dip in the whereabouts.Like this, claw component is preferably in the setting as much as possible of the upper part of upper side member 72a.More specifically, 85 lower end is preferably 10 to 30mm scope to the distance of claw component 47 from slope shape surface.Although claw component 47 can be processed by metal, plastic resin and other different materials, a kind of special preferable material is a MC nylon, because MC nylon is difficult on lithography thin plate 46, produce the for example such defective of scratch.
In addition, as shown in Figure 3, piling apparatus 50 is provided with front part 98, and this front part is arranged on piles up the upstream side of platform 52 along direction of transfer.This front part 98 has the shape of essentially rectangular and the shape of slab, and its thickness direction make peace greatly direction of transfer coupling, its length direction and the Width coupling of piling up platform 52.The upper surface of this front part 98 is a little less than the upper surface of belt transporter 42, and the end portion in its downstream is processed to R shape, the inside face in connection downstream.In addition, the inside face that is positioned at the downstream of this front part 98 is configured to: pile up 52 last times of platform this lithography thin plate 46 is placed along direction of transfer when lithography thin plate 46 is fed to, and this inside face forms the plane that is parallel to its short transverse.As shown in Figure 3, a plurality of burner bores 100 with the extension of elongate in shape broad ways are opened on front part 98.Burner bore 100 is horizontally disposed with respectively.It is inner so that provide air to a plurality of burner bores 100 that the air pipe (not shown) is arranged on front part 98.When lithography thin plate 46 was piled up by piling apparatus 50, air was seen off along direction of transfer from a plurality of burner bore 100.This makes at lithography thin plate 46 after belt transporter 42 is admitted to; Perhaps between lithography thin plate 46 and lithographic plate printed web 46, forming air layer between lithography thin plate 46 and the deposition surface 54 at once, and lithography thin plate 46 moving resistance of mobile (slip) on deposition surface 54 is reduced through inertia also.
Hereinafter, operation and the behavior like the piling apparatus 50 of above structure will be described.
At first, in the time of when lithography thin plate 46 is sent to accumulation platform 52 by belt transporter 42 on, lithography thin plate 46 is placed on the deposition surface 54, continues because inertia moves along direction of transfer simultaneously.At this moment, air is seen off from the burner bore 100 of front part 98, and air layer is along the lower surface formation of the lithography thin plate of being sent into by belt transporter 42 46.This air layer reduced the lithography thin plate 46 sent into by belt transporter 42 and deposition surface 54 or the lithography thin plate 46 piled up between friction drag, and the lithography thin plate 46 on the deposition surface 54 moves along direction of transfer reposefully.In addition, the position of elevator 56 (see figure 2)s adjustment deposition surface 54 or lithography thin plate 46 is so that remain constant altitude.This has guaranteed not to be deposited in by falling along continuous lithography thin plate 46 roughly same position on deposition surface 54 of sending into by belt transporter 42 influence of the quantity of the lithography thin plate 46 on the deposition surface 54.
The lithography thin plate 46 that is sent on the deposition surface 54 by belt transporter 42 continues because inertia moves along direction of transfer, and its front end surface begins to contact with a pair of back member 58.Therefore, the check plate 60 of back member 58 receives weight and the corresponding load of speed with lithography thin plate 46.Acceptance is moved to direction of transfer from the check plate of the load of lithography thin plate 46 60, makes coil spring 70 compressive deformations simultaneously, and receives the dumping force from cylinder 66 at this moment.This has eliminated the kinetic energy of lithography thin plate 46 and has alleviated as the impact load from back member 58 to the application force of lithography thin plate 46.In addition, when lithography thin plate 46 stops when direction of transfer moves, back member 58 extends central siphon through the restoring force of coil spring 70, and through check plate 60 with lithography thin plate 46 along with the sender in the opposite direction towards front part 98 pushings.
When lithography thin plate 46 receive from the back member 58 thrust the time, air layer is still residual along lithography thin plate 46 lower surface.Therefore, the lithography thin plate 46 of thrust that receives from back member 58 moves towards the direction of front part 98 on deposition surface 54 reposefully, and surface, its rear end begins to contact with front part 98.At this moment, back member 58 through from the dumping force of cylinder 66 with enough slow speed extending central siphon 68, begin to contact front part 98 until lithography thin plate 46.When lithography thin plate 46 began to contact front part 98, back member 58 made check plate 60 contact lithography thin plates 46.Therefore, lithography thin plate 46 is placed on and front part 98 position contacting along direction of transfer.
Yet only such operation of piling apparatus 50 will cause following problem.When lithography thin plate 46 is piled up; The fore-end of lithography thin plate 46 strikes the check plate 60 of back member 58; And the shape (bow action generation) on lithography thin plate 46 flexural deformations to similar mountain, this bow action possibly strike the surface of next lithography thin plate 46 that arrives and possibility scratch lithography thin plate 46.In addition, when lithography thin plate 46 was piled up, air remained in the lithography thin plate 46 times.Therefore, the whereabouts of lithography thin plate 46 cores is later than its end portion, and produces bow action.As a result of, the scratch of the end portion of lithography thin plate 46 possibility is deposited in the surface of the lithography thin plate 46 on the deposition surface 54.
Further, when lithography thin plate 46 crooked or its line of centers when being transmitted by belt transporter 42 departs from the line of centers of direction of transfer, depart from the line of centers on slope shape respect to one another surface 85 along the line of centers of the lithography thin plate 46 of direction of transfer.Under this situation, lithography thin plate 46 is admitted to piling apparatus 50 with out-of-alignment state, and this moment, the end portion of lithography thin plate 46 broad wayss was placed (not suitably balance) equably between slope shape respect to one another surface 85.As a result of, when lithography thin plate 46 fell to deposition surface 54, lithography thin plate 46 possibly tilt at Width.
In fact, be not only above-mentioned lithography thin plate 46 along sending into the end portion of direction, and the surface of the lithography thin plate 46 also maybe scratch piled up of the end portion that is positioned at the sheet width direction.
Thus; According to the present invention, as described above, a pair of side member 72 is provided with: a pair of lower side member 72b; This is much the same to the width that lower side member 72b is configured to distance and lithographic plate printed web 46 between it, and the motion of restriction lithography thin plate 46 on Width; Pair of upper side member 72a; This is arranged on lower side member 72b top to upper side member 72a; Among the upper side member 72a each is provided with the moving part that can move along the sheet width direction, and is formed with on it and becomes the roughly slope shape surface 85 of V-arrangement against each other.In addition, thus being provided with control convenience 110 controls this to the distance between the upper side member 72a through driving this moving part to upper side member 72a.
In addition; The angle θ on the slope shape of that pair of upper side member 72a respect to one another surface 85 confirms as and with respect to the horizontal plane becomes more than 25 ° and less than 65 ° angle; And a pair of lower side member 72b is provided with the claw component 47 that can give prominence to and regain, thereby this claw component against each other.
Fig. 5 has shown the stacking method according to piling apparatus of the present invention, and has especially shown the general operation of side member 72 and the behavior of the lithography thin plate 46 relevant with this operation.
State when the state A of Fig. 5 has shown when lithography thin plate 46 is fed to accumulation platform 52 from belt transporter 42 on.After lithography thin plate 46 is admitted to; Make the distance between the double-type end portion on slope shape respect to one another surface 85 be narrower than sheet width through controlling distance between the double-type upper side member 72a respect to one another at once, the lithography thin plate 46 that this is admitted to is placed between the double-type slope shape respect to one another surface 85.When lithography thin plate 46 was placed between the slope shape surface 85, its angle θ with respect to the horizontal plane formed more than 25 ° and less than 65 °.If less than 25 °, being used to correct lithography thin plate 46, the angle with respect to the horizontal plane on this slope shape respect to one another surface 85 makes lithography thin plate 46 evenly be placed on this corrective force between slope shape respect to one another surface is difficult to produce.If slope shape surface 85 is with respect to the horizontal plane with more than 25 ° and less than 65 ° angle tilt; Even the line of centers along direction of transfer of the lithography thin plate of sending into continuously on the belt transporter 42 46 departs from the line of centers on slope shape respect to one another surface 85; When lithography thin plate 46 was admitted to, corrective force was applied in and is used for departing from of central line.Therefore, the left and right sides of lithography thin plate 46 is placed on the slope shape respect to one another surface 85 simultaneously equably, thereby has guaranteed that lithography thin plate 46 falls continuously and normally accumulation.If this angle surpasses 65 °, be placed on the upper part on slope shape respect to one another surface 85.Increase because fall to the distance of deposition surface 54, this lithography thin plate 46 maybe the medium dip in the whereabouts.
Shown in Fig. 5 state B, rely on the inertia of the lithography thin plate 46 be admitted to and from the air-flow of air-blast device 100, lithography thin plate 46 moves along the direction of the member towards the back.At this moment, between the double-type upper side member 72a respect to one another apart from Be Controlled, to such an extent as to enlarge gradually along with the motion of lithography thin plate 46.So the core that is placed on the lithography thin plate 46 between the slope shape respect to one another surface 85 is because its deadweight downwarping.Like above description, because during its deadweight downwarping, the rigidity of this lithography thin plate 46 increases when the core that is placed on the lithography thin plate 46 between the slope shape respect to one another surface 85.Therefore, when the check plate 60 of the fore-end of lithography thin plate 46 and back member 58 contacted, the fore-end of lithography thin plate 46 can not fall downwards.
Then, Fig. 5 state C has shown when lithography thin plate 46 and has moved to the state when being about to begin to contact before with back member 58.At this moment, making control makes distance between the end portion on double-type slope shape surface 85 greater than the width of lithography thin plate 46.So lithography thin plate 46 falls towards deposition surface 54 with reclinate state.Before lithography thin plate 46 is about to fall, claw component 47 from deposition surface 54 tops lower side member respect to one another 72b on even keel outstanding.So this claw component 47 temporarily receives this lithography thin plate 46 that falls.Even the lithography thin plate 46 that falls from slope shape respect to one another surface 85 tilts at its Width to the left or to the right, this inclination can be able to be given prominence to and withdrawal so as the claw component of this lithography thin plate 46 of temporary reception 47 correct.For example, suppose that lithography thin plate 46 is not placed between the slope shape respect to one another surface 85 equably, and the angle θ on above-mentioned slope shape surface 85 can not correct this inclination.So, this lithography thin plate 46 with along its Width to the left or to the right the bevelled state fall.Even in this situation, the claw component 47 that level is outstanding can temporarily receive lithography thin plate 46, so that correct reliably.Received ground lithographic plate printed web 46 by claw component 47 and have a shape, the two ends of lithography thin plate 46 broad wayss are placed with same height here, and slightly downwarping of core.The downwarping of lithography thin plate 46 at this moment is big when not being placed between the slope shape surface 85.In addition, because lithography thin plate 46 is temporarily to be received by claw component 47, the position of lithography thin plate 46 broad wayss is by lower side member 72b decision, this lower side member 72b form with lithographic plate printed web 46 roughly be same size.Correspondingly, might correct the inclination of lithography thin plate 46 on its Width reliably, and this lithography thin plate 46 is placed on predetermined accumulation position.
Shown in Fig. 5 state E, when claw component 47 was regained in this state, lithography thin plate 46 kept horizontality roughly to fall imperturbably from predetermined top, accumulation position.This can prevent that lithography thin plate 46 from falling and the inclination on its Width along the fore-end that is admitted to direction downwards, thereby has prevented that reliably lithography thin plate 46 edges are admitted to the surface of the fore-end and the lithography thin plate that two end portion scratches on its Width have been piled up of direction.
It should be noted that; That a pair of slope shape surface 85 broad ways in the state C of Fig. 5 is extended; But between lithography thin plate 46 falls through lower side member 72b and be placed on 54 last times of deposition surface, upper side member 72a returns initial position (Fig. 5 state E).
Correspondingly, the control convenience 110 of foundation piling apparatus of the present invention repeats above-mentioned program, thereby has prevented that the quality that is caused by the lithography thin plate that lithography thin plate 46 scratches that are admitted to have been piled up from reducing.
It should be noted that; Air layer forms along the lower surface of the lithography thin plate 46 that is admitted to; This air layer makes the core protuberance of the lithography thin plate 46 in the above-mentioned piling apparatus 50, and the end of this lithography thin plate 46 possibly contact with the surface that is deposited in the lithography thin plate on the deposition surface.In this situation, extrusion equipment preferably is arranged on piles up the flat-bed top, thereby be used to spray air the approximate centre part of lithography thin plate 46 is depressed from the top towards piling up platform.As an instance of this extrusion equipment, air nozzle is considered.This air nozzle is connected to the air source (not shown), and for example air blower, compressor perhaps similarly are used to provide the device of air.The air that provides from air source is sprayed to the approximate centre part of lithography thin plate 46.At this; Usually consider on the air duct that connects air nozzle and air source, electromagnetic valve to be set; And this electromagnetic valve Be Controlled, thus air duct is opened when lithography thin plate 46 is piled up, and this air duct is closed when piling apparatus shuts down.Like above description; Pile up be provided with on the platform extrusion equipment can prevent when lithography thin plate 46 during by accumulations air remain under the lower surface of lithography thin plate 46; Thereby reduced protuberance bow action further, and the sheet surface that has prevented to have piled up is by scratch in company with effect lithography thin plate 46 cores together of above-mentioned upper side member.
In addition, slotted opening preferably cuts out in the check plate 60 of back member 58.The slotted opening of this check plate 60 can provide the space, and this space is used for air and under the lower surface of the lithography thin plate 46 that is admitted to, discharges.Aspirator system also can be considered to be arranged near the check plate 60.Be arranged on and pile up platform rear side (near check plate 60) and be used for the space that air is discharged under the lower surface of lithography thin plate 46; Perhaps be provided for absorbing the aspirator system of air; Can reduce the protuberance bow action of lithography thin plate 46 cores further, thereby the sheet surface that has prevented to have piled up is by scratch.
Be placed on the lithography thin plate of piling up on the platform 52 46 and be piled into multilayer, it is forward and backward, both sides are aligned with each other.When the quantity of the lithography thin plate 46 on the deposition surface 54 reaches predetermined when piling up the quantity of bag transportation standard or similar of limiting; This lithography thin plate 46 is piled up bag 102 as one and is transported to tray or similar devices from piling apparatus 50; And be transferred into packing and transportation program; Perhaps store freight house, perhaps similarly local.
Should be noted that description of the invention concentrates on the lithography thin plate, but other sheet material can be used also by it.Like above description, according to the piling apparatus consistent with the present invention, the sheet material that is admitted to is partly received by the slope shape of upper side member.So the distance between two upper side members is stretched to and is equal to or greater than sheet width.Thus, sheet material falls to a kind of state to be piled up on the platform, and wherein the core of sheet material is with respect to the deposition surface indent that becomes, and its two end portion are partly supported by slope shape simultaneously.Therefore, the end portion of sheet material does not fall, and the falling speed of the sheet material that falls can be lowered.Correspondingly, the present invention can prevent that the terminal scratch of sheet material has been deposited in the surface of the sheet material on the deposition surface.
In addition, description of the invention concentrates on the situation that sheet material is piled up, and wherein this sheet material is connected with the sheet material of elongated shape again, yet, even the present invention can be applied to not having the situation that the sheet material of long and narrow sheet material is piled up.
