The operation for counting comb 91,93,95,97 can be controlled in different ways.Counting the two different of comb can
Can operation order respectively as shown in Fig. 4 A, 4B, 4C and 5A, 5B, 5C, and will briefly describe below.Count the movement quilt of comb
Control into the stacking for allowing to produce the interfolded sheet material of predetermined quantity.
Come in an alternating manner with reference to two pairs of counting combs 91,93,95,97 in Fig. 4 A, 4B, 4C, are controlled (i.e. with time-shifting side
Formula) execute identical operation, i.e., first pair counting comb 91,93 executes and combs 95,97 identical operations with second pair of counting.Scheming
In 4A, second pair of counting combs 95,97 downward (direction Y) movement to remove folding sheet material S1, S2 from interfolded roller 9,11
First stacks SK1, allows the second of folding sheet material S1, S2 to stack SK2 and is formed on first pair of counting comb 91,93, and first
91,93 are combed positioned at the underface of the interfolded clamping part 9,11 in the front of interfolded clamping part 13 to counting.
In figure 4b, first pair of counting comb 91,93 has moved downward a short stroke, to allow the second stacking SK2 to increase,
And first stacks SK1 via second pair of 95,97 discharge of counting comb.In this step, the stacking SK2's that support is shaping
First pair counts comb 91,93 and is about moved downward with stacking the speed that increases, i.e., with the height of the stacking formed with its by
Gradually increased speed moves downward.
Second pair of counting comb 95,97 can will stack SK1 and be discharged on a conveyor, and the conveyer is along the direction orthogonal with figure
It removes and stacks SK1.
After having unloaded the first stacking SK1, second pair of counting comb 95,97 comes into upper position (along respective direction Y
Movement).In figure 4b, second pair of counting comb 95,97 is in rest position.The direction of comb 95,97 along axis X is spaced each other
It opens, so that they do not interfere interfolded roller 9,11 and the operation of disengaging pawl 21,23 (to be not shown in Fig. 4 A, 4B, 4C in this stage
In sequence), and interfolded roller 9,11 and disengaging pawl 21,23 continue on the first pair of counting comb 91,93 moved gradually downward
It forms second and stacks SK2.
Once required amount of interfolded sheet material S1, S2 are stacked on first pair of counting comb 91,93, second pair
It counts comb 95,97 just to move towards one another along the direction of axis X, therefore SK2 and next input sheet separation will be stacked.While or
Immediately in later, the movement (along axis Y) downwards of comb 91,93 is counted.In this way, first pair of counting comb 91,93 to
Under (along the direction of axis Y) movement to remove the second stacking SK2 while, third stack SK3 can start second pair count
(as shown in Figure 4 C) is formed on number comb 95,97.
It is appreciated that 91,93 and 95,97 pairs of sequences are combed in two pairs of countings from the brief description above with reference to Fig. 4 A, 4B, 4C
The sheet-stacking of formation executes identical movement.This may be beneficial for machine programming, because control software becomes
It is simpler.
When a pair count comb 91,93 or it is a pair of count comb 95,97 and be in lower position when, the heap that can will be supported on
It is folded be discharged in such as withdraw from band etc, be orthogonal to Fig. 4 A-4C (being parallel to axis 9A, 11A) extension withdraw from conveyer
On.Fig. 4 A, 4B, 4C operation mode in, two pairs of countings comb 91,93 and 95,97 is adapted for carrying out from neighbouring interfolded and presss from both sides
The upper position (combing 95,97 see, for example, the counting in Fig. 4 B) for holding portion 13 withdraws from position to the neighbouring lower part for withdrawing from conveyer
Stroke, for example, see counting comb 95,98 in Figure 4 A.
However, not being the only possible mode that operation count is combed with reference to Fig. 4 A, 4B, 4C disclosure.Fig. 5 A,
In 5B, 5C sequence, each stacking SK1, SK2, SK3 are partially formed to be counted on comb 91,93 with a pair of, and is partly formed
On counting comb 95,97.Comb 95,97 is only counted to be responsible for that the stacking of formation is discharged on withdrawing from conveyer.In other words, often
It executes on first pair of counting comb 91,93 to a stacking cycle portions and is partly executed on second pair of counting comb 95,97.
In stacking the initial step formed, each stacking SK1, SK2, SK3 is by counting 91,93 support of comb, until stacking
Until the step of being transmitted to second pair of counting comb 95,97 from first pair of counting comb 91,93.
More specifically, when 91,93 and second pair of counting comb 95,97 is combed in first pair of counting is in same level, that is, locate
It when identical height, counts comb 91,93 and is opened, i.e., be separated from each other on the direction of axis X, to be discharged in stop place
Second pair waited counts the stacking formed on comb 95,97.Once the stacking formed is combed in second pair of counting
95, it transmits on 97, first pair counts comb 91,93 and just moves upwards and back to the positions of neighbouring interfolded clamping part 13,
They will wait next stacking period to start there.
Meanwhile second pair of counting comb 95,97 is moved downward with stacking forming speed, while growth being supported to stack.When first
When stacking SK1 completion, counts comb 91,93 and be closed (that is, moving along axis X with close to each other) again, and second pair of counting comb 95,
97 stack certain speed further (axis Y) movement downwards of growth rate to be greater than.Once second pair of counting comb 95,97 is
Through reaching drain position, they are separated from each other (movement along axis X) just to be discharged just from first pair of counting comb 91,93
The stacking received.
As long as stacking SK1 has been discharged from second pair of counting comb 95,97, this second pair counting comb 95,97 is transported upwards
It dynamic (direction Y) and is moved again to count at first Dui on the position below comb 91,93 close to each other (direction X).Therefore,
It is properly positioned this second pair and counts comb 95,97 to receive formed and temporarily counted by first Dui and comb the next of 91,93 supports
A heap SK2.
The stacking formed is counted into comb 91,93 from first pair there and is transmitted to second pair of position for counting comb 95,97
Setting, which can according to need, is adjusted, and can carry out selecting based on the sheet material quantity of each stacking and can be selected as making
The dynamic that comb 91,93 and 95,97 must be counted is to optimize, i.e., dynamic load minimum thereon.
Separation is stacked by being inserted into counting comb 91,93 in sheet material stream high speed to obtain.Each counting comb with sheet material and
Disengaging pawl 21,23 in phase (moves) insertion along axis X.When sheet material second from the bottom is detached from from related folding roller and passes through phase
Disengaging pawl label is closed when heap is stacked on (outside that the distal end of disengaging pawl is located at the periphery of the first interfolded roller 9), insertion
First counts comb.When being stacked last sheet material and related disengaging pawl is still when heap is stacked on, insertion second counts comb and has come
It is separated at stacking.Second counting comb is to count to comb an out of phase sheet material relative to first.During separation phase or immediately in
After separation phase, counts comb 91,93 and move downward to support the advance newly stacked.Therefore, according to Fig. 5 A, Fig. 5 B and Fig. 5 C
Shown in operation mode, first pair of counting comb 91,93 moves up and down a short stroke required for (axis Y), to allow just in shape
At be stacked between interfolded roller 9,11 and first pair of counting comb 91,93 and increase.On the contrary, second pair of counting comb 95,97 is held
The longer vertical stroke of row, with from this to removing each stacking in interfolded roller 9,11.
In two kinds of operation modes (Fig. 4 A-4C and Fig. 5 A-5C), the adjustable movement counted in the X-direction combed,
In order to by the stacking SK completed from by interfolded roller 9,11 transmit Lai entrance interfolded sheet material stream in isolate
Come.For this purpose, for example, the close of direction along the axis X for the counting comb for separating the stacking completed and next sheet material moves
It is out of phase, because before two one movements counted in comb start from another.In other words, comb is counted along the side X
To can be close to movement it is asymmetrical, i.e., it is asynchronous.
In addition, the movement for counting comb is synchronous with the pivoting action of disengaging pawl 21,23, in order to always clamp from interfolded
Each completed stacking SK is separated in the continuous interfolded sheet material stream of the entrance in portion 13.
