Abstract
ABSTRACT OF THE DISCLOSURE
A device for uniformly overlapping flat stiff objects, especially blanks, comprises a yieldable baffle above a conveyor with drive elements being driven at the same speed and located forwardly and rearwardly of the baffle. Force applied to one of the objects by the rear drive element is transmitted by the latter to displace the baffle thus permitting that object to pass between the baffle and the conveyor.

Description
10~97~0 In the processing of flat objects, especially blanks m~de of stiff material, often there is a need for objects which have been delivered in an irregular sequence onto a belt, to b~e uniformly overlapped as a conveyor belt carries them along.
It is the purpose of the invention to provide a device ~hich will position the flat objects with the same degree of overlap.
The invention is a device for overlapping flat rigid objects comprising a conveyor supported by a first conveyor element and a second conveyor element, a displaceable kaffle means mounted above and bebween said first acnveyor element and said second conveyor element, said second conveyor element being upstream said baffle means, the conveyor forming a passage through which said flat objects may pass in controlled manner, the second conve~Dr element being adjustable to a position at a distanca from said baffle which distance is less than the length of a single objeat, whereby the forae applied to one of said cbjects by said second conve~or el3ment is transmitted to said ba1e and the baf1e yields thus enlarging the passage and allowing the object to pass therethrough.
In the devioe according to the invention, the baffle is controlled without any special sensor and drive. The thrust applied to an object by the rear drive element is used to actuate the baffle, so that it does not hold back the objeat. The object, which is acted upon by the said rear drive ele~ent, shields the next overlying object from the feed action of the r~Ar drive element until the rear edge o the moving object leaves the rear drive element. By altering the distance between the rear drive element and the baffle, the degree of overlap may be determined. The closer the drive element to the baffle, the greater the degree of overlap.
m e baffle preferably has a sloping stop. This kind of design produces, at the baffle, a reaction force of the feed force applied to the object, a force component of which raises the baffle against the force of gravity and against an adjustable spring force.
Since uniform overlapping requires that the objects be backed up, the speed of the drive elements is controlled by means of a sensor which ~ ' .
:. .
~0~9760 senses the height of the backed-up objects. This speed is increased when there is a large or an increasing back-up; it is reduced when the back-up is small or decreasing.
Acoording to one embodiment of the invention, the same speed of the two drive elements may be obtained, while the degree of overlap still remains the same, by providing the two drive elements with a common conveyor belt which, between the baffle and the rear drive element, is lower than a feed conveyor.
The invention is explained hereinafter in greater detail in conjunc-tion with the drawing attached hereto of a diagrammatic example of embcdiment in side elevation.
Blanks 2 of stiff material are carried in an irregular arrangement ~with varying amLunts of overlap), on a conveyor belt 1, in the direction of arr~w 3. The said blanks could be conveyed separate from each o~h3r. The said blanks pass from conve~or belt 1 to a lcwer level, where they back up and orm an accum~lation 4.
This accumwlation 4 forms in ront of a baffle 5 having a sloping stop 6, as shown in the drawing. Arranged under the track, in the vicinity of accum~lation 4 is a roller or second conveyor element 7 over which a conveyor belt 10, passing over deflecting rollers 8, 9, runs. Between second conveyor element or roller 7 and passage 12, formed by baffle 5, conveyor belt 10 is offset in a downward direction in relation to the feed plane at passage 12 and roller 7. Immediately ahead of passage 12, this feed plane consists of a plate or grid 22 comprising recesses for belt 10 in the vicinity of drive element 7. The design of belt 10 may vary. It may, for instance, consist of a plurality of separate narrow belts passing upwardly through the grid in the vicinity of roller 7. Or it may be in the form of a wide belt, with plate 22 running on each side thereof.
In the direction of travel 3,and behl~d baffle 5, belt 10 runs in the feed plane over first conveyor element guide roller 13. A belt 18, running over roller guides 16, 17, hinged to baffle 5, rests upon overlapped blanks 2 and is carried along therewith. The degree of overlap is thus retained as

Baffle 5, which is vertically adjustable, is maunted in a holder 20 which is ada~ted to pivot about an axis 19 and`bears against a stop 21. ~affle 5 may be pushed upwardly against the force of a spring 14 having an adjust-able pre-load.
When an accumulation 4 is formed in front of baffle 5, conveyor belt 10 applies a force, in the vi~inity of roller 7, to lowermost blank 2.
Since this blank is relatively stiff, this conveying force is transferred to sloping stop 6 of baffle 5. The resulting reaction force m~ves baffle 5 upwardly against the force of spring 14. The blank seized by conveyor belt 10 in the vlrinity of roller 7 can then pass through gap 12. The blanks lying above the aforesaid blank are still held back, assuming, of course, that there is not too much friction between the blank being conveyed, and the blank lying thereabove. This condition is u9~11y fulfilled in the case of lac~uered blanks and no problems therefore arise. As soon as blank 2 seized by roller 7 on belt 10 leaves the said belt at the said roller, transportation is a~fected entirely by front drive elements 10, 13 extending as far as gap 12.
