CN1004689B - Conveying line of annular stacking paper feeder - Google Patents

Abstract

The invention relates to an annular stack feeder conveyor line for conveying stacks by means of an endless conveyor. On this conveyor line, a form roller 4 is mounted, the end journal 5 of which rests loosely on a rolling bearing 7. The form rolls are mounted close to each other so that the end journals of the two form rolls run on one bearing. If the installation distance is too large, a reinforcing sliding plate 3 needs to be additionally arranged between the two rollers. The upper edge of the slide plate should be flush with the bottom of the guide groove 9 in the profile roll. The vehicle 10 is accommodated in these guide grooves. The shaping rollers are preferably arranged in the stacking table 1, but also in the sheet-fed transport table 12; but also for the steering section, but in this case each end journal needs to be supported by three bearings.

Description

The travel line of ring-shaped stacks feeder

The version of the transportation means transportation stacking that the present invention relates to usefulness cycle operation stacking feeder to the printing processing machine device.

Before about 90 years, a kind of ring-shaped stacks feeder has been proposed on German patent specification 87411.This stacking feeder is that two circulating conveyer belts are installed on solid upper stages.This conveyer belt guides by bending roller, and turns back to upper stages again through carrying roller.In upper stages, that is to say on load-transfer device, put stacking and sign indicating number one-tenth flakey.Make stacking through being transported to behind the bending roller on the same solid lower table by load-transfer device, and overturn, promptly the stacking bottom is put into topmost, thus just can make easily the bottom but present superincumbent paper carries out individual conveying.Simultaneously, the design of the propulsive effort of load-transfer device is relevant with individual traffic condition of the stacking that betransported.

This principle of work is used today always.But just replaced two load-transfer devices now, and with many load-transfer devices by upper stages and walk around bending roller.This as German Democratic Republic patent DD-PS72545 and 104956 disclosed.

The shortcoming of all these class ring-shaped stacks feeders is, because the weight of stacking can produce sizable pressure on load-transfer device and upper stages, therefore need overcome very big friction force when carrying.Big like this friction force can cause stacking to do impact type motion, promptly so-called "blind"effect again.Therefore, concerning the paper of some type, "blind"effect can produce on lepidiod paper echelon and tear phenomenon, the space occurs, and this can cause fault at paper again when individual transmits continuously.

Another shortcoming is because friction force is bigger, in order to carry the paper buttress that complete code is flat, just needs sizable energy resource consumption.

Another shortcoming is exactly that load-transfer device can produce shifted laterally when being placed on load-transfer device and the upper table by the flat paper buttress of sign indicating number, and this just may make paper edge suffer damage.

The objective of the invention is to design a travel line of being convenient to the transported sheet buttress, on sizable degree, avoid damaging paper, and individual conveyance of sheets serially.

Basis of the present invention is a design ring-shaped stacks feeder, makes when filling stacking, can not cause the load-transfer device side travel, reduces friction between stacking bench board and the lepidiod pile buttress greatly, reaches higher transportation stability and individual transmission stability.

The travel line of ring-shaped stacks feeder of the present invention especially is equipped with the shape roller on the bench board of stacking, roller is provided with end journal, is used as the supporting-point of shape roller with it, and is placed on loosely respectively on two antifriction-bearing boxs.Antifriction-bearing box is preferably outstanding to be placed on the axle bolt.Also can adopt suitable plain bearing to replace antifriction-bearing box, but its friction coefficient is not so good as the little of antifriction-bearing box.On the shape roller, to be processed with guide groove, its shape will with therein the operation means of delivery, match as belt, rope etc.

The shape roller can make two shape rollers of laying each other to move on an antifriction-bearing box mutually near laying like this.If the shape roller is installed with big distance, then to consider between two shape rollers, to lay a slide plate that rigidity is big.The slide plate upper limb must be contour with the guide groove bottom, so that means of delivery can move on sustained height.As low equipment equipment rate (it is relevant with stacking work platform length), be on the stacking bench board, only to need a shape roller is installed, just can reach desirable effect (if mode of operation also be simple simon says).

When considering that throughput direction changes in advance, for example in the turn-around zone of ring-shaped stacks feeder, also will be to the 3rd supporting-point of each end journal installing.

On individual conveying workbench of ring-shaped stacks feeder, reasonably arrange the shape roller, can further help improving plant efficiency.

Use an embodiment below the present invention is described.

Fig. 1 is the lateral plan of travel line upper stages;

Fig. 2 is the diagrammatic side views of travel line upper stages, and this figure directly shows mutual configuring condition between Fig. 3 I-I section place shape roller;

Fig. 3 is the birds-eye view of travel line upper stages shown in Figure 2;

Fig. 4 is the schematic side view of a ring-shaped stacks feeder, there is shown the situation of the turn-around zone of being made up of the shape roller, but the load-transfer device that do not draw;

Fig. 5 is shape roller structure enlarged drawing when non-horizontal transmission direction in the part A of Fig. 4.

As seen from Figure 1, the stacking bench board 1 of ring-shaped stacks feeder is subjected to the restriction of the trusses 2 of upper stages both sides, the connecting each other between the trusses side of not drawing among the figure.The slide plate 3 that has been reinforced is installed in the trusses 2.Respectively be equiped with a shape roller 4 between two slide plates 3 in the corresponding way, this shape roller 4 is placed on the outer shroud of antifriction-bearing box 7 loosely with its end journal 5.In trusses 2, antifriction-bearing box 7 is installed on the axle bolt 8.Have guide groove 9 on the shape roller 4, its structure is consistent with the means of delivery 10 of band shape or rope form.The degree of depth of guide groove 9 will be enough to avoid when loading onto with the flat pile of sign indicating number, and means of delivery 10 is jumped out in guide groove 9.With the profile of the means of delivery 10 corresponding guide grooves 9 of being packed into, add and be put in the shape roller 4.

In order further to avoid the cliding friction between stacking and the stacking bench board 1, according to Fig. 2-4,4 on shape roller is also wanted mutually near laying.Antifriction-bearing box 7 will reasonably be installed on the axle bolt 8, so that each antifriction-bearing box 7 is used for supporting two shape rollers 4 simultaneously.In the structure of turn-around zone 11, available shape roller 4 replaces bending roller, and shape roller 4 can be semicircle shape and arrange.Their end journals of shape roller 4 usefulness 5 of Bu Zhiing are placed on three antifriction-bearing boxs 7 like this.Shown in Fig. 5 embodiment, the reasonable Arrangement of antifriction-bearing box is related to the power transfer situation.

Shape roller 4 is placed on individual transfer table and also suits.Low friction by means of the flakey stacking is carried, and can reduce the propulsive effort of ring-type stacking feeder.
