Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail.But, persons of ordinary skill in the art may appreciate that in each embodiment of the present invention, proposing many ins and outs to make reader understand the application better.But, even without these ins and outs with based on the many variations of following embodiment and amendment, each claim of the application technical scheme required for protection also can be realized.
First embodiment of the present invention relates to a kind of creasing method of automatic cutting machines.The method controls the upper-lower position of head by controlling depth of cup.
Carry out in the process of impression treating rapidoprint, control the adjustment amount that head moves up and down, obtain distance-sensor by distance-sensor and treat the distance between impression material, first creasing mechanism least significant end is moved to the position for the treatment of impression, then the amount adjusted downwards by controlling head controls the depth of cup that creasing mechanism treats rapidoprint, thus obtains the consistent impression of the depth.Said impression device least significant end refers to the height never contacting fabric at impression device and moves downward herein, contacts the position of fabric at first.
Specifically, the distance that can first adopt distance-sensor to respond to obtain perpendicular below, its present position and treat between impression material, then according to responding to the distance obtained, and the position relationship between distance-sensor and creasing mechanism, calculate creasing mechanism least significant end and treat the distance between impression material surface.If creasing mechanism least significant end and treat that the distance between impression material is greater than 0, then control creasing mechanism and move downward, until creasing mechanism least significant end and treat that the distance between impression material equals 0, now creasing mechanism least significant end with treat that impression material contacts.Now, make the creasing mechanism evolution of heat, then control head and adjust downwards, adjustment amount can determine according to the degree of depth for indentation.
Second embodiment of the present invention relates to a kind of creasing method of automatic cutting machines.The method obtains the distance between creasing mechanism least significant end and table top, deducts predeterminable range, obtains the adjustment amount of creasing mechanism; If the adjustment amount of creasing mechanism is not 0, then adjust the upper-lower position of creasing mechanism, until the adjustment amount of creasing mechanism is 0; Wherein, predeterminable range equals to treat that the thickness of impression material deducts depth of cup.Move up and down because automatic cutting machines can control head, make the distance between creasing mechanism least significant end and table top be predeterminable range, creasing mechanism can be made to follow the motion of cutting table top, thus obtain the consistent impression of the depth, promote impression effect.
Specifically, the downward adjustment amount of head can be controlled according to the distance between creasing mechanism least significant end and table top.That is, if the distance between creasing mechanism least significant end and table top is greater than predeterminable range, then controls creasing mechanism and move downward, until the distance between creasing mechanism least significant end and table top equals predeterminable range.Here predeterminable range should be remaining thickness after material indent locations to be processed is etched.This situation is particularly suitable for the consistent situation of material thickness to be processed.
In order to accurately determine the adjustment amount that creasing mechanism moves up and down further, coordinate system can be set up.After setting up coordinate system, the coordinate of each point on creasing mechanism least significant end, table top can be determined, accurately determine the distance between creasing mechanism least significant end and table top, thus control the position of creasing mechanism.
Specifically, the protective layer laid above whole Cutting table or Cutting table can be scanned in advance, set up table top coordinate database; Wherein, table top coordinate database comprises the Z coordinate of each point on table top.Such as can set up coordinate system as shown in Figure 1, in figure, X-axis positive direction is the width of Cutting table, and Y-axis positive direction is the length direction of Cutting table, and Z axis positive direction is perpendicular to Cutting table towards upper direction, and O is the origin of coordinates.When head is in the origin position of X and Y, the upper-lower position of adjustment head, it is made to be in the determined origin position of original point position mechanism, employing is arranged on head bottom, distance-sensor near creasing mechanism obtains the distance between the table top of perpendicular below, its present position, with the distance now obtained for benchmark; Head moves with Y-direction in X direction, obtains the distance between the table top of perpendicular below, its present position, then deduct benchmark, obtain the Z coordinate of each position, record X, Y, Z coordinate of each position in each position employing distance-sensor.Because table top coordinate database comprises the Z coordinate of each point on table top, therefore, in Indentation Process, the distance between head and table top can be controlled, realize head and follow the motion of cutting table top.Again because creasing mechanism is generally positioned at head bottom, and the position of creasing mechanism is relatively fixing, therefore, when determining head center of gravity position coordinates, also can determine the position of creasing mechanism least significant end.In simple terms, scan whole table top by following method, set up table top coordinate database:
Adopt original point position mechanism, determining table areal coordinate initial point;
Employing distance-sensor obtains the distance between its present position and table top;
According to the distance that distance-sensor obtains, and the position relationship between original point position mechanism and distance-sensor, calculate the Z coordinate of each point on table top.
In Indentation Process, according to the position relationship between creasing mechanism least significant end and table top, the distance-sensor being arranged on head bottom can be adopted to determine to treat the upper surface coordinate of impression material, then search corresponding table top Z coordinate, thus obtain the degree of depth of the downward impression of creasing mechanism exactly.Specifically, distance-sensor can be followed head and be moved to and treat Indentation position, distance-sensor is moved to and treats Indentation position, distance-sensor can be measured present position and treat the distance between impression material upper surface, when creasing mechanism moves to this position, the Z coordinate of its least significant end should be greater than the Z coordinate that Indentation position upper surface treated by material, that is, determines that head is the need of adjusting up and down and adjustment amount size with this.Idiographic flow as shown in Figure 2, comprises following steps:
Step 201, moves to distance-sensor and treats Indentation position, and induction obtains the distance that itself and vertical lower are treated between impression material.
Step 202, according to responding to the distance obtained, and the position relationship between distance-sensor and original point position mechanism, calculate the Z coordinate treating the upper surface of Indentation position material;
Specifically, distance-sensor is when measuring the distance between current present position and material, and head can be adjusted to the position measuring Z initial point, the distance measured like this deducts benchmark, the Z coordinate being the upper surface treating Indentation position material obtained.
Step 203, in coordinate database, searches the Z coordinate treating Indentation position vertical lower table top.
Step 204, according to the size of creasing mechanism and the position relationship with original point position mechanism thereof, calculates the Z coordinate of creasing mechanism least significant end.
Step 205, moves to the upper surface treating impression material by creasing mechanism least significant end.
Step 206, opens creasing mechanism (making creasing mechanism produce heat), controls creasing mechanism simultaneously and move downward.
Step 207, calculates the difference between the Z coordinate of creasing mechanism least significant end and the Z coordinate of creasing mechanism vertical lower table top, obtains the distance between creasing mechanism least significant end and table top.
Step 208, judges whether the distance between creasing mechanism least significant end and table top is predeterminable range, if not, then returns and performs step 206; If so, the impression process of this position is then terminated.
For example, as shown in Figure 3, in figure, dash area is for treating impression material, original point position mechanism position is A, current creasing mechanism least significant end is E, range sensor present position is B, and range sensor vertical lower treats that impression material upper surface is C, and range sensor vertical lower cutting table top is D; Creasing mechanism least significant end need move to C from A, and then downward impression is to F.When determining the coordinate of C, head can be moved to the state of scanning Cutting table, now distance-sensor measures the distance (T namely in figure) treating impression material upper surface, deducts benchmark, and that obtain is exactly the Z coordinate (Z treating Indentation position vertical lower material upper surface
c).According to the position relationship of creasing mechanism least significant end E and original point position mechanism, be exactly the L in figure.Also the Z coordinate (Z of creasing mechanism least significant end E can be determined
e).From table top database, search the Z coordinate (Z obtaining treating Indentation position table top
d).
Before creasing mechanism least significant end is moved on to C from E, first can calculate the distance t=Z between C and D
c-Z
d, and the distance t=Z between E and D

dif d>t, then need to move down head (mobile head is equivalent to move creasing mechanism); If d≤t, then need the head that moves up.It should be noted that, if d=t needs slightly to rise entire machine head, just mean creasing mechanism least significant end because equal and treat that the upper surface of impression material is in same level, if now move creasing mechanism, the surface of attacking material possibly, slightly to rise entire machine head, this damage can be avoided.
After creasing mechanism least significant end is moved to the upper surface treating impression material, open creasing mechanism, control creasing mechanism simultaneously and move downward.The degree of depth that creasing mechanism moves downward, calculates current creasing mechanism least significant end coordinate Z
ewith the coordinate Z of Cutting table table top
fbetween difference d determine; Along with creasing mechanism moves downward, d reduces gradually, until d is close to 0, namely, and Z

dduring for predeterminable range, then terminate the impression process of this position.
The step of various method divides above, just in order to be described clearly, can merge into a step or splitting some step, being decomposed into multiple step, when realizing as long as comprise identical logical relation, all in the protection domain of this patent; To adding inessential amendment in algorithm or in flow process or introducing inessential design, but the core design not changing its algorithm and flow process is all in the protection domain of this patent.
