Detailed description of the invention

With reference to accompanying drawing, L represents the driving surface of known printer 100, the entirety of 100 finger known type chopping machines; As mentioned above, driving surface L can move in outer stroke N1 and return of stroke N2, as shown in Figure 2, to outer stroke N1 and return of stroke N2 all with the plane orthogonal of paper.

Whole Equipment of the present invention Reference numeral 10 represents, is placed in the side of driving surface L docking station S.

Described equipment comprises gantry 1, described gantry 1 known devices 2A and 2B support works face 3, and the top set 4A of the closed loop conveyer 4 that described driving surface 3 is supported by described gantry is formed; In the illustrated embodiment, described conveyer is made up of belt conveyor 80A, 80B, 80C and 80D that a series of side is relative, and described belt conveyor 80A, 80B, 80C and 80D are wrapped in common driven roller 90A and common driven voller (not shown).

Described loading surface 3 is driven by the motor (not shown) of known type can (direction X1, X2) upper motion in the vertical direction.

Described conveyer 4 can load onto stepping or continuous working motor (adopt known way, do not show), to make top set 4A can translation in the Y direction; Note, longitudinal expanding unit of top set at least equals the longitudinally height of driving surface L, and its width at least equals the width of driving surface L.

The acception station 70 of the sheetpile 15 of flat board 200,300 is placed on relative platform 30A, 30B, is positioned at the offside of driving surface L, relative with side, gantry 1.

The depth B of sheetpile is not more than the width of driving surface L print zone; The longitudinal size of sheetpile 15 is not more than the longitudinally height of print zone.

Fig. 3 is the printable maximum breadth of flat board 200 of chopping machine 100; Fig. 4 is the dull and stereotyped breadth 300 being less than maximum possible breadth.

In Fig. 2-4, the flat board 20 supported by loading surface 3 captures and adopts generic representation method, because they can be made in any way with transfer device M.

Below the operation of present device is described.

Operator will at least a pile 15 be put in acception station 70.

According to the height H (indicating with dotted line in Fig. 2) of described heap relative reference line " O ", still with reference to figure 2, loading surface 3 produces translation to be positioned at the head slab place of described heap 15; The first control position K (indicating with dotted line in Fig. 2) of loading surface 3 is consistent with the height H of described heap.

The alterable height of the first control position K, because the height of the first control position K depends on the height of sheetpile, the height of sheetpile reduces along with constantly collecting head slab from sheetpile.

Described equipment 1 comprises the detecting device of described sheetpile 15 head slab height and the detecting device of loading surface 3 height: because these devices belong to prior art, therefore do not represent by numbering.

Now, starter gear M, first captures the head slab of sheetpile 15, transfers on loading surface 3 afterwards, be loaded into described head slab more precisely on the top set 4A of conveyer 4.

With shifted simultaneously be (device M and described head slab depart from), re-move loading surface 3 (direction X1 or X2) with the best intended orientation making loading surface 3 obtain the docking station S of opposite working L, thus the second control position Q (Fig. 2) determines, because it is the function of the height of driving surface L.

This makes the grabbing device MP associated with chopping machine docking station S capture the described head slab be positioned on conveyer 4 top set 4A, to be located at (control step see using dotted line U instruction in Fig. 2) on chopping machine driving surface L.

Described head slab is transferred to driving surface L from top set 4A and is optimized by the variant shown in Fig. 7 A, 7B.

This variant comprises and is parallel to each other and is positioned at mutually level a series of axle 50, gap 60 place of each axle between Liang Ge adjacent conveyor belts top set opposite side; Each axle 50 has longitudinal pressed flat 50A.

Described axle 50 loads onto synchronous dynamo with known system, and is placed to the axle that can not disturb relative pressed flat 50A and remain static R, and the top supported near belt conveyor is dull and stereotyped: see Fig. 7 A.

Described axle 50 rotates (control position W) on P direction simultaneously makes described flat board rise (thus being separated with belt conveyor) to chopping machine docking station translation (arrow G): this can help grabbing device MP to capture described flat board.

Electric machine makes the vertical movement of loading plane 3 according to the detecting device of sheetpile head slab and the detecting device of loading surface; These device combinations determine the first control position K and the second control position Q.

Fig. 3 is dull and stereotyped maximum breadth; The head slab 200A of sheetpile transfers on the top set 4A of belt conveyor 4; In this case, top set does not move.

Fig. 4 is the flat board that breadth is less than maximum breadth.

The head slab 300A of sheetpile 15 is placed on the start-up portion (position Z1 represented by dashed line in Fig. 4) of conveyer 4 top set 4A by device M; Simultaneously, top set 4A in the Y direction translation is greater than a segment distance of dull and stereotyped longitudinal size (i.e. Y-direction): described conveyer moves in a stepwise manner in operation therewith.

Like this, a series of dull and stereotyped 300 are just placed on top set 4A (position Z1, Z2, Z3...), until all longitudinal extension parts of branch 4A are completely capped; Described a series of flat board is transferred on driving surface L by device MP by this.

Once and between flat board transfers to top set 4A from sheetpile 15 by another time, described loading surface 3 vertical translation is to be cyclically placed on the first control position H and the second control position Q: this optimizes dull and stereotyped transfer.

Also comprise another variant of conveyer 4, described conveyer moves (see Fig. 5 and Fig. 6) continuously under driving, and this is advantageous particularly.

With reference to figure 5 and Fig. 6,55 represent the bearing that the translation direction Y of relative conveyer 4 top set laterally places.

Each bearing is made up of a kind of rake, and its pointed tooth 56 is placed in gap 60 and size can ensure freely to insert described gap.

Downstream bearing 55A fixes, and other bearings (by known method, not showing) can move to elevated position A2 (as shown in phantom in Figure 6) from lowered position A1 (as shown in solid line Fig. 6).

At elevated position A2, pointed tooth 56 is for be positioned in conveyer top set and the corresponding flat board arranged forms the bearing of equal number at its upstream; In this case, dull and stereotyped and there is dragging effect between belt conveyor below.

At lowered position A1, pointed tooth 56 does not disturb dull and stereotyped displacement in the Y direction.

When dull and stereotyped for maximum breadth 200 (Fig. 3), bearing 55 remains on lowered position A1; Like this, each flat board transferred on conveyer 4 is against on fixed bearing 55A.

When breadth when dull and stereotyped 300 is less than maximum breadth, such as shown in Figure 4, the starting of described bearing 55 and flat plate gripping and transfer device M is synchronously carried out circulation and is started (lowered position A1 and elevated position A2), thinks that each dull and stereotyped 300 determine position Z1, Z2 and Z3.

In the preferred embodiment of described equipment, only use a pile; This makes only to move a pile to described station 70, has all advantages that it can bring.

In the end in a station without any jacking system, make use of the space that in prior art, jacking system occupies like this; And, contribute to entering loading surface 3.

Because loading surface can perpendicular movement, optimize the operation at sheetpile top gripping flat board, to transfer on loading surface and to transfer to the operation the driving surface L of chopping machine by flat board from loading surface.

In a variant of the present invention, as shown in Fig. 8 A, 8B, 8C and 9, described equipment comprises longitudinal expanding unit conveyer parallel with longitudinal expanding unit of loading surface 3 16 further, described conveyer 16 be placed in the same plane of described equipment on (especially, from the planar view of described equipment, relative with the side of loading surface 3) and extend to acception station 70 from the upstream of loading surface 3.

Especially, structure and the size of described conveyer 16 should guarantee to support the relative pile in multiple side 15 (particularly many groups, often group is made up of the relative pile 15 in side and opposed platforms 30A, 30B), and (stepping or continuous) can be started so that each pile 15 is transferred to acception station 70 (on the first working direction V, as shown in arrow in Fig. 8 A-8C and Fig. 9) from loading depot 160.

In other words, by this variant, each pile 15 supported by opposed platforms 30A, 30B can be loaded on conveyer 16 by known device in loading depot 160 by operator.

Then, conveyer 16 transfers to acception station 70 (see Fig. 8 A) by disposable for pile 15 after starting, and wherein to pick up mode described above for paper.Picking up in the process of paper from pile 15, described conveyer 16 obviously stops using (situation of Fig. 8 B).

Picked up all paper in a pile 15 once described crawl and transfer device M, conveyer 16 restarts, and hollow panel 30A, 30B is transferred to the discharge point 161 in acception station 70 downstream.Meanwhile, another pile 15 is sent to acception station 70 (particularly seeing Fig. 8 C).

Advantageously, this variant can improve the capacity rating of described equipment and all print systems, decreases pile 15 and is placed in acception station 70 in advance and acception station 70 empties time needed for rear transfer platform 30A, 30B.This variant equipment can comprise sensor 18 (particularly as shown in Figure 8 A and 8 B) further, described sensor device 18 is arranged, to be sent to by pile 15 motion that conveyer 16 was detected and removed in acception station 70 along the extension of the conveyer 16 being positioned at loading depot 160 downstream and acception station 70 upstream.

In other words, sensor device 8 detects being transferred in acception station 70 by pile 15, and removes the motion of conveyer 16 to make crawl and transfer device M pick up paper.

Advantageously, this specification sheets can optimize the operation of present device further for prior art.

Such as, or conveyer 16 by operator's hand starting and releasing, can also realize by acting on button (not illustrating this situation).

In the preferred embodiment shown in Fig. 8 A, 8B, 8C and 9, conveyer 16 comprises roller conveyor.

Or described conveyer 16 can comprise two roller conveyors that mutual adjacent alignment is placed, the first and second roller conveyors.

The following describes with the variant shown in Fig. 9 especially favourable for the pile of phase mutual different parameters, the pile 15,15 ' of such as different materials.

In this variant of the present invention, described equipment comprises the waiting station 162 being placed in acception station 70 downstream (with loading depot 161 upstream) further.

And, described conveyer 16 extends to waiting station 162 (therefore beyond acception station 70) from loading depot 160, to transmit pile 15 ' (on the first working direction V after motion) to waiting station 162, described pile 15 ' keeps standby mode after arriving acception station 70, capture relative paper with transfer device M until capture and to be transferred on chopping machine 100 (pile 15 ' of the determination material such as will processed subsequently, this hereinafter can clearly).

In particular, described conveyer 16 above can move (along equidirectional), again pile 15 ' can be transferred to acception station 70 from waiting station 162 at the second working direction V ' contrary with the first working direction V in addition.

According to this variant, described equipment can comprise reading device 19 further, described reading device 19 is arranged along the extension (between loading depot 160 and acception station 70) of conveyer 16, whether to check each pile 15,15 ' to transmit to waiting station 162, this hereinafter can be clearly.

Can load two or more pile 15,15 ' on conveyer 16, to transfer to acception station 170 carrying out print procedure, wherein each pile is made up of the paper of different materials simultaneously.But it is inconsistent that pile 15,15 ' installs to the order that the order on conveyer 16 effectively may be processed by chopping machine 100 with pile 15,15 '.Usually, some print job is carried out to the paper of same material, to be necessary to process (or shifting to same chopping machine 100) the paper of same material before print job completes.

Therefore, print at the paper of the first material, and the pile 15 ' of the second material is when being just sent to acception station 70, described pile 15 ' is temporarily transferring to waiting station 162 (conveyer 16 is moved on the first working direction V), until the sheet processing of the first material completes.At this moment, make conveyer 16 in the upper motion of the second working direction V ', to process the pile 15 ' of the second material.

Each platform 30A, 30B of support pile 15,15 ' are upper to be comprised, such as, and bar code; Bar code is for identifying the material type of the pile 15,15 ' supported by platform 30A, 30B.In this case, described reading device 19 can comprise, such as, where necessary, the bar code reader (namely when being made up of the material different from the material of the paper processed according to the reading determination pile 15 ' of bar code) for pile 15,15 ' is transmitted to waiting station.

Fig. 9 is above-mentioned variant, especially the pile 15 of the first material, and crawl and transfer device M will pick the paper of the first material, and another pile 15 ' of the second material is in standby mode in waiting station 162.

Advantageously, owing to can avoid stopping print procedure and can optimize net cycle time, therefore for the pile 15,15 ' of different materials, this variant is especially flexible.
