The specific embodiment

At first with reference to Fig. 1 and 2, stack device or entire system represent that with Reference numeral 1 it comprises a plurality of conveyers, and these conveyers are successively set between the input end and mouth of device in order.In an example shown, device 1 comprises two row conveyers, and this two row conveyer all starts from the input end of device, ends at two storage platforms different, that be used for paper buttress heap respectively.Be construed as: this is a kind of possibility structure of device, and generally, device can have the single-row conveyer that is equipped with single storage platform, perhaps can have the above conveyer of two row that is equipped with two above cardboard stacking platforms.The utility model can only be applied to the single-row conveyer or the above conveyer of row of same device.In an example shown, as the explained in detail of back, the utility model only is applied to form the row conveyer in the two row conveyers of device 1, and designs another row conveyer in a conventional manner.

Particularly, device 1 shown in the drawings comprises the first row conveyer and secondary series conveyer, 3 expressions of the first row conveyer entirety by reference numeral, and 5 expressions of secondary series conveyer entirety by reference numeral, secondary series conveyer 5 is positioned on the first row conveyer 3.

The first row conveyer 3 comprises the first conveyer 3A, the second conveyer 3B, the 3rd conveyer 3C and the 4th conveyer 3D; They arrange successively in order that along the transport path of carrying cardboard F1 cardboard F1 moves to mouth according to the input end of direction shown in the arrow f3 from transport path through conveyer 3A-3D.Member 7 is connected with the first conveyer 3A through known manner, and is that the imbrication mode is arranged cardboard with the overlapping mode in part.Anchor clamps 9 are connected with the second conveyer 3B and are supported by support 11, and support 11 can move back and forth along conveyer 3B.For example can produce and control anchor clamps 9 and support 11 according to american documentation literature US-A-5626336 number described content, further detailed content please refer to this piece american documentation literature.

The cardboard F1 that is transferred along the transport path that is defined by conveyer 3A-3D is discharged on the platform 13, and platform 13 is positioned at the downstream of the mouth of conveyer 3D and also can vertically moves according to direction shown in the double-head arrow f13.Fig. 1 has shown the buttress heap P1 that just is formed on the platform 13.Cardboard F1 is carried by the part along the path that conveyer 3A-3D defines overlappingly, and one cover another ground and be unloaded on the buttress heap P1 that just is being formed, and remains on the standing height place basically through reducing the upper end that platform 13 makes buttress pile P1 gradually.Adjustable supporter 15 is arranged on the mouth front of conveyer 3D, highly is higher than the flat-bed position, and the cardboard F1 against part 15 that is transferred along the path of being defined by conveyer 3A-3D stops.

In embodiment illustrated, this part of device 1 is for example worked like the american documentation literature US-A-5626336 number disclosed the sort of mode of having mentioned basically with known manner work.

Fig. 1 has shown the stage that buttress heap P1 just is being done, and the cardboard F1 that is arranged on the conveyer 3D must be stacked on the buttress heap P1.On the upstream portion of conveyer 3D and conveyer 3C, do not have cardboard F1, this is because it is essential that the above-mentioned zone in the path forms this spacing, to guarantee in case when accomplishing buttress heap P1 just with its unloading, reorientate platform 13 then.Can form this spacing with known manner: the delivery speed through regulating single conveyer 3A-3D, and keep the first cardboard F1 of continuous paper sheets series motionless through the anchor clamps 9 that support by support 11.

Secondary series conveyer 5 comprises the first conveyer 5A; Member 21 is at the input end of the first conveyer 5A; It is overlapping with the part to be that the imbrication mode is arranged the cardboard that will be stacked on the platform 23, and platform 23 is arranged on the path output that is defined by secondary series conveyer 5 and can on vertical, moves according to direction shown in the double-head arrow f23.The second conveyer 5B is arranged on the downstream of conveyer 5A, and the anchor clamps 25 that supported by support 27 are connected with the second conveyer 5B, and the 26S Proteasome Structure and Function of anchor clamps 25 is similar to the anchor clamps 9 that supported by support 11.The 3rd conveyer 5C is arranged on the downstream of conveyer 5B, then is provided with conveyer 5D in the downstream of the 3rd conveyer 5C, piles P2 at the mouth unloading cardboard of conveyer 5D on vertical movable platform 23, to form buttress.Supporter 29 is arranged on platform 23 tops, and its function class is similar to the supporter of having mentioned 15.

Although buttress heap P1 is that buttress heap P2 is tied by a plurality of paper and forms through the stacked parallelepiped shape buttress heap that forms of all cardboards, these paper are tied with M1, M2, M3 and M4 and are represented in Figure 1A.In Fig. 2, buttress heap P2 is done, and in this example, buttress heap P2 ties M1-M7 by seven stacked paper and forms.Paper tie M1-M7 with respect to the throughput direction of the cardboard that forms buttress heap P2 in a lateral direction (promptly perpendicular to Fig. 1,1A, 2 and the in-plane of 2A on) one with respect to another ground alternative arrangement.Fig. 3 schematically illustrates the layout that paper is tied.Each paper is tied M1-M7 and is tied laterally staggered with respect to the paper of its underpart.Like this, the paper of just can be easily each paper being tied M1-M7 and its underpart at subsequently working stage is tied and is separated.

Fig. 3 has schematically shown two adjacent buttress heap P2, representes that the transverse width of this system can allow the more cardboard of parallel running.In an example shown, the paper bale amount of two buttress heap P2 and size, cardboard size equate.But also can make the structure between the buttress heap different, for example, can pile by parallel production two buttress, the cardboard and the paper bale amount of each buttress heap equate, but the cardboard size is different.

Make the buttress heap P2 that is formed on the platform 23 according to direction cross motion shown in the double-head arrow fM (Fig. 3) through design platform 23, thereby alternative arrangement paper is tied M1-M7.To be described as producing this motion and method of designing that platform 23 is adopted with reference to Fig. 3 and 4 below.

Valuably; Tie the regular arrangement of M1-M7 and do not need horizontal alternative arrangement to form the single cardboard that each paper is tied in order to obtain single paper; Accomplish buttress heap P2 and accomplishing each paper when tying, can interrupt the cardboard stream on the conveyer 5A-5D of secondary series conveyer 5.

Fig. 1 has schematically shown the cardboard stream that is subdivided into a succession of cardboard group, and each cardboard group all is used for forming paper and ties M1-M7.Particularly, in Fig. 1, F2 representes to be arranged in one group of cardboard on the conveyer 5D, is used for accomplishing the paper that just is being formed on the platform 23 and ties M5.Cardboard group F3 is arranged in the upper reaches of cardboard group F2, is separated with one section zone of not arranging the cardboard group between between the two cardboard groups.In addition, cardboard group F4 is located at the upper reaches of cardboard group F3, and it is arranged in, and conveyer 5C goes up and cardboard group F3 separates.The cardboard group is not arranged at least the second half zone of conveyer 5B, and cardboard group (representing with F5) in succession is almost completely on conveyer 5A.

Basically be and the identical mode of interruption when the process that forms single buttress heap P1, P2 finishes obtains among cardboard group F2, F3, F4, the F5 the one group spacing between organizing with another.Practically, can regulate the conveyer element speeds suitably quickens to carry downstream cardboard group, slows down and carry upper reaches cardboard group.As american documentation literature US-A-5626336 number disclosed, slow down to carry upper reaches cardboard group, and keep conveyer 5B to shut down to keep first cardboard in each cardboard group along conveyer 5B through the anchor clamps 25 that supported by support 27.Patent documentation US-A-5626336 interrupts cardboard stream, will pile up neatly and pile discharged method on the storage platform then when having described buttress heap and being done.But; Be construed as: same method of operation can be used for making little cardboard group F2-F5 to be separated from each other; Thereby, when accomplishing paper and tie, form before cardboard that paper in succession ties arrives, be formed on laterally (the arrow fM direction indication) translation of buttress heap P2 on the movable platform 23.Like this, carrying from conveyer 5D under the situation of cardboard, the buttress heap is always according to direction side travel shown in the arrow fM, thereby cardboard keeps correct location not in its alternative arrangement in a lateral direction.

In fact; Because the required time of translation buttress heap obviously is less than from storage platform and discharges the buttress heap, makes platform return to the required time of original position then on a direction or other directions, thereby the distance that is used for forming between the continuous paper sheet group that continuous paper ties can be very narrow.In fact; In order to form narrow-pitch; The work speed of conveyer can only slow down; Thereby the work speed through under work speed, move forward the downstream cardboard group and the downstream cardboard group that slows down forms this spacing, causes reducing the spacing that form previous stage with regard to the acceleration of avoiding downstream cardboard group occurring like this.

Usually,, can the different operation method be provided flexibly, only reduce or only increase work speed, maybe will reduce work speed and increase work speed and combine according to the different working condition when the user programmes when changing the speed of conveyer.

Fig. 2 and 2A have shown the stage when 7 paper are tied the formed buttress heap of M 1-M7 P2 and have been done.The length in zone of not arranging cardboard on the conveyer 5D is greater than cardboard group F3-F5 and consecutive cardboard component are opened required length.Like this, do not carry cardboard to platform 23 during this period of time can be longer; Need remove the buttress heap P2 (or the buttress that forms simultaneously heap P2) that has been formed and then lifting platform 23 (that is, immediately platform being positioned under the conveyer 5D outlet cardboard that first paper that is used for forming continuous buttress heap P2 with reception is tied M1) during this period of time.

Make platform carry out traverse motion in the following manner according to direction shown in the arrow fM.

Platform 23 comprises that the parallel roller 33 of frame 31, row is installed on the frame 31, and they are around separately axis rotation, and the axis of these rollers and buttress heap or the buttress that just is being formed are piled P2 and become 90 ° according to the traverse motion direction of arrow fM.In an example shown, each roller is subdivided into two parts of representing with

Reference numeral

33A and 33B respectively.Part 33A forms gravity roller carrier, and belt conveyor 35 is provided with around the part 33B of roller 33, thereby forms storage surface forms buttress heap P2 with storage cardboard.

In an illustrated embodiment, each roller 33 has groove 34, and belt conveyor 37 is engaged in the groove 34, activates the motion that axle drive shaft 39 is produced through motor 41 and is received by groove 34.Axle drive shaft 39 is arranged on roller 33 belows and becomes 90 ° of location with roller.Motor 41 is applied required motion with pair of rollers 33, thereby is made load-transfer device 35 carry out appropriate exercise by centralized control unit 43 controls shown in Fig. 4 signal.This motion to following either way be useful: come the buttress heap P2 that translation just forming through the crank motion shown in the double-head arrow fM, thereby back and forth staggered paper is tied M1-M7; And, unload the buttress heap that has been formed through for example direction shown in the arrow fP (Fig. 4) or its rightabout motion of translation.

Thereby, can form common buttress heap P1 and tie the buttress heap that M1-M7 constitutes with said apparatus by each laterally staggered each other paper.

Although be understood that in embodiment illustrated; The secondary series conveyer that is in top 5 and platform 23 controlled to form have the buttress heap P2 that staggered paper is tied; The first row conveyer 3 to being in the bottom forms parallelepiped shape buttress heap P1 with platform 13; But; Through appropriate program design, also can form to have buttress heap that staggered paper ties and form parallelepiped shape buttress heap or form with the lower member 3 and 13 of device and all be to have that buttress that staggered paper ties is piled or all be that the buttress of plane hexahedral shape is piled according to production requirement with the parts up and down of device with the upper member 5,23 of device.

In an example shown, storage platform shown device, that be used for cardboard buttress heap can progressively move downward.Also can adopt different structure: platform remains on the standing height place and the progressively lifting of conveyer quilt; The mouth of end feed device can increase along with the height of buttress heap and raise like this, just can always keep suitable distance with the terminal cardboard that forms the buttress heap.

Be appreciated that for: accompanying drawing has only shown the actual example that is provided that is provided with of the utility model, and still, under the situation that does not break away from the implicit essential scope of the utility model, the utility model also can alternation of form and setting.Reference numeral in the appended claims only is used for coming easy-to-read to understand claims according to specification sheets and accompanying drawing, does not limit the protection domain of claims.
