Embodiment
Fig. 1 shows sheet feeding device, it is from the downside of the stacking 2 of pending paper, card or other thin materials
Extract sheet material.2 are stacked to be shelved in feeding station 4.Feeding station 4 is preferably tilted from horizontal direction, and is limited by feeding block 6
System stacks 2 and moves under the effect of gravity, wherein the leading face paste of stacking 2 is leaned against on the feeding block 6.Feed block 6 and feeding
Small―gap suture between platform 4 allows once to extract a sheet material out from the bottom for stacking 2 and passes through the gap.It is arranged in feeding station 4
The downside of transport band 8 and bottom sheet be frictionally engaged and drive it to pass through gap towards roller 10.
The details of feeding station 4, feeding block 6 and transport band 8 is conventional and does not form the part of the present invention.Can be with
Use the sheet feeding device of replacement；It is all it is important that single sheet of material is along one every time, the direction substantially perpendicular to axis
Ground is driven towards roller 10.It note that this is not meant to that conveying direction must be pointing directly at axis；Preferably, its aiming axis
Above line.In rectangular sheet in typical case, the leading edge of every sheet material aligns the axis for being basically parallel to roller.
Roller 10 is installed into be rotated around horizontal axis.Multiple blades 12 are equally spaced apart from around the periphery of roller.At this
There are five blades 12 in example.Blade 12 is roughly parallel to the axis extension of roller 10, and outwards launches from the surface of roller.Each leaf
Piece 12 is bent backward preferably relative to the direction of rotation of roller 10.Roller 10 or blade 12 is not necessarily set to extend across feeder
Whole width.Two or more rollers 10 that width reduces can be spaced apart along single axis, and each roller has its own
One group of blade 12.Alternatively, the two or more groups blade 12 that single overall with roller 10 can be reduced with support width.Blade 12 can be with
It is integrally formed with roller 10, or blade can be attached on roller.Latter selection is carried using more complicated manufacturing process as cost
The advantage of independent selection material is supplied.Blade 12 is flexible and submissive to avoid damaging sheet material and allow described below
" springing " acts.They can be made of the material of such as rubber, it can capture sheet material and contribute to draw when rotated
Guide card material crosses roller 10.
It is an output table 14 in the downstream of roller 10, for receiving the sheet material of a succession of trailing laminated.As shown in the figure, output
Platform 14 is not necessarily to align with input feeding station 4, and preferably it extends below roller 10.Platform 14 can be laminating machine or by piece
The estrade for other machines that material feeder provides.As described below, there is provided gate 18 for use as it is as described below optionally
Sheet material is prevented to move away from the barrier of roller 10.Gate 18 can include the one or more that can be risen by the groove in platform 14
Tooth.The gate of other known form can be used for the present invention.
Output driving mechanism 16 can be associated with output table 14, for a series of sheet materials to be extracted out from roller 10 and along defeated
Put into effect for 14 next stages for pulling to the process, such as laminating machine.In the shown embodiment, output driving mechanism is separated including a pair
Roller 16,17.When fall gate 18 with allow sheet material by when, while fall upper roller 16 so that sheet material is clipped in upper roller 16 and roller
Between 17.Drive at least one roller in the two pairs of rollers so that sheet material is between the roller 16,17 of reverse rotation by pushed downstream.
The output driving mechanism of the other forms synchronous with gate 18 is also possible.In some applications, inclined output table 14 can
It can be enough the sheet material for moving outflow under the influence of gravity, without any extra output driving mechanism.
Fig. 2 illustrates the operation of the present invention.In this case, continuous sheet material 21,22,23 is shown as along feeding station
4 seriatim advance, rather than are extracted out from the downside of stacking.This is in order to make it easy to understand, but being also to fall within the scope of the present invention
Possibility.For the sake of simplicity, input driving mechanism and output driving mechanism is not shown in the schematic diagram of Fig. 2.
Fig. 2 (a) shows the first sheet material 21 to advance along feeding station 4 towards roller 10.First sheet material 21 small―gap suture it
Rear molding is with there is the second sheet material 22.The gap is determined by the timing of supplied upstream mechanism, and is not required.Feeding station 4 is put down
The face preferably just top of the axis of alignment roller 10 so that the first half of the leading edge of the first sheet material 21 towards roller 10.As schemed
Show, leading edge enters the space between two blades 12.
Roller 10 is continuously rotated in a manner of the superficial velocity of roller 10 is faster than the conveying speed of sheet material 21.Therefore, blade 12
Leading edge than sheet material 21 moves more quickly than and does not stop the traveling forward of sheet material.The leading edge 24 of feeding station 4 is preferably only located at
In the range of the scanning of blade 12 so that when roller 10 rotates, edge 24 is caught in the outer end of blade 12.Due to being flexible, Mei Geye
Then piece 12 is bent backward, until its tip is by edge 24, and due to being elastic, blade 12 and then springs forward
To recover its original-shape.Gap between this arrangement most of the time closing feeding edge of table 24 and blade 12, and therefore
Prevent the leading edge of sheet material 21 from passing through in the lower section of roller 10.When blade springs forward, the tip of blade 12 is also set quickly to transport upwards
Dynamic, this helps sheet material 21 lifting the top of roller 10, as described below.
Fig. 2 (b) shows the moment after Fig. 2 (a) soon, when the continuous rotation of roller 10 makes by feeding edge of table
During the contacts-side-down of 24 12 and first sheet material 21 of a blade, then sheet material 21 has been lifted off the top of roller 10 by the blade
Portion.Sheet material 21 is still moved forward with the speed determined by input driving mechanism, and input driving mechanism continues to act in feeding station 4
Sheet material 21 rear portion.Meanwhile roller 10 is rotated with sufficiently high speed so that the downside of the inswept sheet material 21 of continuous blade 12 is simultaneously
Keep the raised position of sheet material.
Fig. 2 (c) shows further process, as the first sheet material 21 has further moved across the top of roller 10, directly
No longer acted on to its trailing edge by input driving mechanism, and its leading edge starts to be acted on by output driving mechanism.Rotating vane 12 with
Friction between the downside of sheet material 21 can help to keep sheet material to move forward in the transition period.
In Fig. 2 (d), further process of first sheet material 21 away from roller 10 is stopped that the gate hinders it by gate 18
Leading edge.Alternatively (or in addition), the movement of sheet material 21 can be stopped by the operation of interrupt output driving mechanism.Therefore,
One sheet material 21 is in 10 upper stationary of roller and is supported on rotating vane 12.Meanwhile second sheet material 22 have progressed to Fig. 2 (a)
In the location of the first sheet material 21, its leading edge is close to roller 10 and penetrates the space between two blades 12.3rd sheet material 23
The second sheet material 22 is trailed along feeding station 4 now.
In Fig. 2 (e), after a moment, the second sheet material 22 by the lasting rotation of blade 12 and elevated so that
The over top of roller 10 is supported on rotating vane.In addition to the first sheet material 21 has existed, second in Fig. 2 (e)
The position of material 22 is identical with the position of the first sheet material 21 in Fig. 2 (b).Therefore, the leading edge of the second sheet material 22 is pressed with trailing now
Folded relation is located at below the afterbody of the first sheet material 21.The system can be by institute after being stopped from the first sheet material 21 by gate 18
Elapsed time has arrived at desired locations preferably by using sensor (not shown) to detect the second sheet material 22
Determine when the trailing laminated for having reached sufficient degree.Then gate 18 can be made to be stopped and/or can restart defeated
Go out driving mechanism, drive the first sheet material 21 to leave roller 10 to be driven toward the identical speed of roller 10 with the second sheet material 22, from
And the trailing laminated amount needed for keeping.
It is readily apparent that the circulation for the step of showing and describing with reference to Fig. 2 (c)-(e) can be repeated ad infinitum, so that
3rd sheet material 23 and 22 grade of the second sheet material trail laminated.
, can also be with relatively low instead of with the identical speed of input driving mechanism but being operated intermittently output driving mechanism
Speed operates continuously output driving mechanism, the speed is by equal to the average speed in the first embodiment of the present invention just described
Degree.In the first embodiment, the first sheet material 21 stops waiting the second sheet material 22 to catch up with.In the alternate embodiment, based on two
Speed difference between person, the second sheet material 22 will gradually catch up with (and trailing laminated) first sheet material 21, but result will be identical.
Under any circumstance, if the sheet material of a succession of trailing laminated of output is continuous, it reaches the input of next process
It should be moved before with this slower speed.
The quantity of blade 12 can be selected according to the speed of application, the property of pending sheet material and roller 10.Using less
Blade 12, roller 10 will may need quickly to rotate to realize intended effect.As described above, surface of the minimum speed by roller
Speed needs to determine more than sheet material conveying speed.Therefore, roller may need at least three blades just to come into force.More than ten
Blade quantity can not possibly have any benefit；In next blade contact sheet material and before being lifted, greater number of blade will
So that the time that the leading edge of sheet material penetrates between them is less.
Roller 10 can independently be driven by the motor (not shown) of its own.Preferably, driven by being connected to input
The transmission device of motivation structure is driven with appropriate speed.As it was previously stated, roller 10 normally will continuously rotate, but roller relative to
The intermittently operated of the operation timing of gate 18 and/or driving mechanism 8 is also possible.
