Abstract
The utility model belongs to the technical field of the offset printing device fabrication, introduced a sheet -fed offset press's transfer part, including impression anterior segment and transfer back end, the impression anterior segment includes impression cylinder, impression cylinder has set the grippers, the transfer back end is including corresponding simultaneously two sets of transfer mechanisms of impression cylinder, transfer mechanism of every group by a transfer tooth and with the corresponding defeated paper platform of transfer tooth constitutes, the transfer parts still include a switching mechanism who is used for switching over the work of two sets of transfer mechanisms. Compared with the prior art, the utility model has the advantages of the printing links up, and the down time rate is little.
Description
Technical field
The utility model belongs to offset printing equipment manufacturing technology field, relates to a kind of transfer parts of offset press, is related specifically to a kind of transfer parts of sheet-fed offset press.
Background technology
Transfer parts are vitals of sheet-fed offset press, the static paper that it will locate on defeated paper platform, hold in the month accurately and to accelerate to print speed printing speed reposefully consistent.Then it is submitted to accurately the grippers of impression cylinder, or through transfer roller, paper is given the grippers of impression cylinder, print.But when the note detection mechanism before transfer detects that paper need stop transfer extremely, can great infringement work continuity and reduce overall machine running efficiency.
Summary of the invention
The purpose of this utility model is to solve the problem, and when making paper occur abnormal, still ensures the continuity of producing.
Therefore the utility model provides a kind of transfer parts of sheet-fed offset press, it is characterized in that, comprise impression leading portion and transfer back segment, described impression leading portion comprises impression cylinder, described impression cylinder is equipped with grippers, described transfer back segment comprises two groups of feeding mechanisms of corresponding described impression cylinder simultaneously, and described feeding mechanism of often organizing is formed by a transfer gripper and the defeated paper platform corresponding with described transfer gripper; Described transfer parts also comprise one for switching the switching mechanism of two groups of feeding mechanism work.
Preferably, described switching mechanism comprise processing center and with feeding mechanism two sheet detecting apparatus one to one, described sheet detecting apparatus is arranged at defeated paper platform region.Utilize electronic monitoring and mechanical switch to carry out switching action operation, meet the requirement of quick transfer.First carry out work by single feeding mechanism, transfer gripper is by the paper sheet delivery on defeated paper platform to impression cylinder place, and grippers is held paper in the month and then left with impression cylinder; When checkout gear detects that paper occurs extremely; abnormal conditions comprise many hanging togothers, paper sheet askew, single paper stretch smooth, paper is incomplete, capture paper unsuccessfully etc.; processing center controls this feeding mechanism at once and shuts down correction; comprise machinery or manually change paper etc., and another group feeding mechanism of post command carries out work.Design like this can farthest reduce shuts down the loss in efficiency that causes, and shuts down frequently and easily can cause and damage and increase maintenance fine setting frequency by each parts of offset press.
More preferably, described transfer back segment also comprises transfer roller, and described transfer roller is between described impression cylinder and feeding mechanism.
Above scheme preferred, described transfer gripper swings transfer gripper for centering.
Above scheme is preferred again, and described transfer gripper is dynamic axis swing transfer gripper.
Above scheme is preferred equally again, and described transfer gripper is rotary swing transfer gripper.
Also above scheme again is preferred, and described transfer gripper is that override type swings transfer gripper.
Compared with prior art, the beneficial effects of the utility model are:
Printing is coherent, and outage rate is little.
Accompanying drawing explanation
Fig. 1 is the structural representation of the transfer parts of sheet-fed offset press of the present utility model.
Detailed description of the invention
With reference to Fig. 1, this embodiment describes a kind of transfer parts of sheet-fed offset press, comprise impression leading portion and transfer back segment, impression leading portion comprises impression cylinder 1, impression cylinder 1 is provided with grippers 2, and the effect of grippers 2 is to enter impression cylinder 1 for holding the paper sent here in the month.This impression cylinder 1 is corresponding two groups of feeding mechanisms simultaneously, often organize feeding mechanism and form with the defeated paper platform 4 being positioned at transfer gripper 3 rear end by the transfer gripper 3 that is positioned at front end, defeated paper platform 4 is placed with and opens for transfer.Meanwhile, the transfer parts of the present embodiment also include a switching mechanism, and the effect of this switching mechanism is the duty for alternately opening switching two groups of feeding mechanisms.Switching mechanism is formed primarily of two parts, be respectively processing center 5 and checkout gear 6 is formed, checkout gear 6 detects the state of paper, when paper occurs abnormal, processing center 5 switches feeding mechanism in time, to be connected transfer action smoothly, and can arrange automatic repariring equipment on feeding mechanism, rejecting problem paper, to change to initial feeding mechanism in time carrying out work.The selection of this feeding mechanism can be various, comprises centering and swing transfer gripper, dynamic axis swing transfer gripper, rotary swing transfer gripper or override type swing transfer gripper.
