At the remodeling of locking device shown in Fig. 5, wherein, locking bolt 14 is not manually but motion flexibly.The servo-driver 23 that is connected with locking bolt 14 for example can be configured to so-called magnetic relay, and it is pulled out locking bolt 14 from the position of locking first locking device 11 of this locking bolt.In other respects, the locking device shown in the remodeling shown in Fig. 5 and Fig. 4 a to 4d is corresponding.
In Fig. 1, illustrate in addition, go out head piece 10 (referring to Fig. 2) to second and dispose second locking device 12, this second locking device is used for interim sealing second and goes out head piece 10.This second locking device 12 can be configured to the slidingtype locking device and be configured to closing flap in an illustrated embodiment.For this reason, this second locking device 12 can go out head piece and leave saidly to go out head piece and swingingly be bearing in the hinge 13 towards said.
In the container 16 of metering device 3, metering roll 17 is set, on said metering roll, is standing one from storage device 2 powder pillar to the container 16 of trickling.Said post is in the funnel shaped upper curtate of container 16.Said funnel shaped upper curtate has the thin bottom of contracting, and another section of container 16 is connected on the said bottom, and said another section has and the crooked adaptedly wall of metering roll 17.Be arranged on metering roll 17 in the last described section (so-called pump chamber or rotating room) with forming a narrow positions with respect to these metering roll 17 equidistant walls, said metering roll 17 passes said narrow positions with powder and carries downwards.Said narrow positions has the shape of semicircular annular gap basically.Being rotated among Fig. 1 of metering roll 17 schematically shows with arrow.In another section of said container 16, said another section for example can constitute through the pipe that is connected in the said rotating room said metering roll 17 with powder delivery.Powder arrives in the distributor 18 via said section (pipe), and said distributor has pressure air feedway 19 and is used to be mixed into powder-air mixture from the pressure air of said pressure air feedway 19 at powder described in this distributor.Said powder-air mixture flow in the injection apparatus 4 via pipe-line system 20; Said injection apparatus is opened 27 conveying rhythm with said powder-air mixture with the page or leaf of process and is outputed to said page or leaf and open, and carries out spreading and avoids page or leaf to open the fresh printing figure message set-off on 27 when page or leaf is opened stacking so that page or leaf is opened the surface.Said pipe-line system 20 can constitute through flexible pipe.In distributor 18, the powder-air mixture that is produced is assigned on the flexible pipe of said pipe-line system 20 equably.Said powder its from storage device 2 to injection apparatus on 4 the path along the powder delivery direction 30 that schematically shows flow through metering device 3, distributor 18 and pipe-line system 20.
Shown system works as follows: under the situation that storage device 2 is not filled as yet, operating personnel pass first locking device 11 downwards, snap in and till 11 sealings said first of this first locking device go out head piece 9 up to locking bolt 14.Before this or afterwards, second locking device 12 is swung in the position shown in its Fig. 1, these second locking device, 12 sealings said second go out head piece 10 in this position.Then, two powder deposits 28 and 29 are filled in two chambers 7,8.When said two chambers 7,8 were full of by powder respectively fully, the top or the preferred below that are in the level of the powder pillar in second Room 8 or the powder position that " powder position " (to be similar to the address of " liquid level ") is in the powder pillar in first Room 7 perhaps were on the identical height two powder positions.Advantageously, first deposit 28 has and second deposit, 29 roughly the same capacity.
In order to start printing operation; Second locking device 12 is swung open from opening 10; Thereby make powder in second Room 8 only, promptly second deposit 29 can pass second and goes out head piece 10 and trickle lentamente in metering device 3, and makes metering device 3, distributor 18 and injection apparatus 4 startups.
If second deposit 29 exhausts (that kind as shown in Figure 2) fully or reaches predetermined minimum flow in printing operation, locking bolt 14 then gets loose.Back-moving spring 25 is back moved first locking device 11 to thus and is opened first and go out in the position of head piece 9; Thereby making the deposit 28 of winning can pass first goes out head piece 9 and flow in second Room 8; So that replace or additional second deposit 29 that exhausts wholly or in part that kind just as shown in Figure 3.Fall during formula (tandem type) recharges at the said waterfall of second Room, second goes out head piece 10 can temporarily keep shut (that kind just as shown in Figure 3) or keep opening wide by means of second locking device 12.Under both of these case; Printing operation can fall at said waterfall and interruptedly not move during formula (tandem type) recharges, and does not need very many time and during this time interval, be in as the powder deposit in the container 16 of intermediate storage on amount, enough to keep printing operation because this recharges.
Some remodeling are also proposed at last.In a remodeling, can cancel back-moving spring 25 and locking device and first locking device 11 by means of servo-driver for example the electric screw gear drive on both direction, move and go out head piece 9 to open and close first.
In another remodeling (this another remodeling is shown in Fig. 6 to 7b partly), first locking device 11 for open and close first go out head piece 9 purpose can not move along partition wall 6, but can rotate with respect to this partition wall around the axis 21 of partition wall 6.At this, first goes out head piece 9 is processed in first in the circumference of partition wall 6 through a row and connects boring or connect eyelet 32 and a row and be processed in second in the circumference of first locking device 11 of annular and connect boring or connect eyelet 33 formations.Through the rotation of first locking device 11, second connect boring 33 open first effluent 9 o'clock (referring to Fig. 7 b) and first connect that boring 32 overlaps and (a) overlap when going out head piece 9 sealing first with 32 disengagings of first pass through openings referring to Fig. 7.That is, in this remodeling, first effluents 11 works with being similar to rotary valve.
