It is spacing that feeding spaced papers carry out forward.
After feeding spaced papers are placed and finished, the depression bar 9 of both sides is overturn and makes its movable end pressure holding on feeding spaced papers, pressure holding gas
Cylinder 5 is operated so that the pressure holding that lever 52 is up and release is to balancing weight 34, and roller 33 is descending under Gravitative Loads and pressure holding exists
The top of feeding spaced papers.It is specific also the height of lever 52 to be determined with the frictional force needed for playing paper according to the weight of roller 33 when setting
Degree, to cause that there is appropriate frictional force to carry out paper feeding operation between feeding spaced papers for it during the rolling of roller 33.
Treat after the completion of aforesaid operations, paper storing box 2 is pushed forward into, the positioning cylinder 72 on the detent mechanism 7 of both sides is distinguished
In being operated so that locating shaft 73 reinserts the location hole on locating piece 71, realize that paper storing box 2 is determined with the fixation of fixed seat 1
Position.Complete and change paper and corresponding preparation operation.
The automatic document feeder operationally, by drive mechanism 4 orders about roller 33 and rotates, roller 33 just can by its with
Frictional force between feeding spaced papers and feeding spaced papers are one by one released from the front to the back, feeding spaced papers are pushed away forward from the front portion of holding tray 2
After going out, continue forward, the feeding spaced papers to be transferred into needs by follow-up manipulator or other equipment under the guiding of directing plate 6
The top of the product of placement.
In specific setting, the above-mentioned feeding spaced papers automatic document feeder in product line is settable two groups, is sent at one group
After feeding spaced papers have been used on paper device, automatic paper feeding is carried out by another group of paper feeder, can so ensure that production line is protected
Not shutdown operation is held, its production efficiency is greatly improved.
To sum up, the feeding spaced papers automatic document feeder of production line of the present utility model, its simple structure is with low cost, can be real
Now stablize the transmission one by one of feeding spaced papers, the normal transmission and operation of production line are not influenceed, its fault rate is low, and production efficiency is high, energy
Enough be advantageously applied to feeding spaced papers in such as large-size glass substrate product line automatically delivers operation.
