Description
Technical field
The purpose of the present invention is for the automatic cutting one or more overlapping usually in predetermined preparatory window
The method and system of fabric pieces.
Background technique
In the presence of the known machine for automatic cutting fabric, cuts a fabric or cut the fabric pieces of overlapping simultaneously
Stacking (in the term of this field be referred to as " tissue layer "), knitted generally according to the acquisition of existing cutting pattern (pattern) is multiple
Object shape (quantity that each shape is equal to the layer of the overlapping of fabric in quantitative aspects).Then, these shapes be used to make respectively
Kind product, including such as clothes, cover for seat or the fabric for automotive interior etc..These cutting machines include cutting surfaces, are cutting
The cutting head and telecontrol equipment on surface are cut, telecontrol equipment is suitable for making cutting head along two axis for being parallel to cutting surfaces
Line movement, to define cutting region (that is, machine can be in the maximum surface area wherein cut).Cutting head is equipped with for cutting
The cutting element of fabric is cut, the vertical blades typically with high-frequency reciprocating linear motion.Command unit is connected to sportswear
Set and be connected to cutting head, thus issue instruction control they according to the cutting pattern being loaded in command unit come to putting
(one or more) fabric set on cutting surfaces is cut.The cutting process can be held in stepped or continuous mode
Row.In the case where the process of stepping, each step generally corresponds to limit the cutting pattern of cutting window, and cutting window is defined as
Region comprising constituting the shape group of cutting pattern.In tissue layer, usually there is the space of multiple cutting windows.Once cutting
Pattern is completed tissue layer simultaneously and is remain stationary, then tissue layer is just advanced on cutting surfaces, so that fabric is entirely cut what is followed
It cuts and extends on window.In the case where continuous process, the above process is still maintained, but cutting window is in relative to tissue layer
In continuous movement.
For automatic cutting, it is important that fabric is arranged on cutting surfaces, so that it extends throughout entire cutting window,
Command unit will execute cutting action in the entire cutting window.Otherwise, one or more shapes can be imperfect or have scarce
Sunken.For example, such case will occur when the side that tissue layer is arranged as side and cutting region is not parallel.In the feelings
Under condition, even if one or more first cutting window bendings are located in fabric, there is also such risks, that is, cuts in subsequent
It cuts in step, the edge of cutting window will be more than fabric.
In order to avoid such case, before starting cutting action, operator usually check to ensure that tissue layer relative to
Cutting region is sufficiently placed in the middle, and especially its side is fully aligned with the side of cutting region.For this purpose, cutting head
Equipped with laser source, it is suitable for transmission laser beam on the fabric (usually X-shaped light beam).Processed tissue layer is used for when executing
The first cutting process step (and may be in one or more subsequent program step/operation windows) when, operator
Cutting head is taken near the vertex of tissue layer, and typically by laser, his/her fixed origin, that is, operator should
Position inputs in command unit, and therefore command unit knows origin, cutting window should be positioned relative to the origin.It connects
, operator moves cutting head along the first direction for the side for being parallel to cutting region, and checks to ensure that laser beam
It remains in the acceptable distance in the edge away from tissue layer (for example, operator ensures that laser beam will not enter the week of tissue layer
There is the fabric for being unsuitable for production in the perimeter region, or ensure that laser beam will not move the edge away from tissue layer in battery limit (BL) domain
It is too far), and possibly, then since origin, same check is executed along the second direction for being orthogonal to first direction.At this
During step, if the laser beam of projection on the fabric proves the edge of too close tissue layer or transports beyond edge or laser beam
Too far isolated edge is moved, then operator can make origin correspondingly move and (thus relocate cutting window) (in certain limits).
In extreme circumstances, tissue layer must be relocated manually, especially for keeping it placed in the middle again and/or make the side of tissue layer
More accurately it is aligned again with the side of cutting region.
It has been discovered by the applicants that the method for positional dissection window and/or the position for adjusting tissue layer is
It is extremely difficult and/or very long, therefore the downtime is produced in the fabric treating stage.In addition, this is substantially empirical
Method is related to a degree of inexactness.Additionally, in the case where being manuallyd locate to tissue layer, when there are heavy load
When, produce job security problem.

In operation, automatic cutting system 1 described above executes automatic cutting according to the present invention, for fabric
Illustrative methods.
Firstly, method includes stacking 4 with 7 pairs of label of at least two spatial points 8,9 represented in stacking 4 to be marked.
Stacking 4 is marked and preferably includes the sheet that the multiple label 20 is applied to top by (direct or indirect)
On 3.
In one embodiment, label 20 is manually applied by operator.In this case, operator applies label, makes
It obtains the spatial point that label limits in sheet 3 to be aligned relative to each other as much as possible, and is aligned with long side 24.For example, being
This purpose, operator arrange that all labels are in away from the identical distance of transverse edge 24 (for example, to all fabrics to be discarded
Between each label and the edge).
In a preferred embodiment, label 20 is applied automatically by labeller.For this purpose, starting point is (for example, close
First vertex) and part or sheet in placement surface stacking orientation initially, be preferably entered manually in command unit
(for example, second point being aligned by being manually entered near the vertex opposite with the first vertex), so that passing through on label
Spatial point straight line 23 proof be parallel to long side 24.
Then after label processing, stacking 4 is placed on cutting surfaces 2, so that the end sections stacked are located at cutting
In region 5;The end sections stacked include the first vertex, and first label 25 is located near first vertex.
At this time, it is contemplated to the detection to label.
For this purpose, control system 100 initially makes the movement of camera 10 (for example, by the zigzag of cutting head 11
Movement), to be scanned to sheet 3 close to the part that the first vertex includes starting point 8, obtain the relevant digital picture of part
(usually passing through camera electronic device mounted), until the QR code of the first label is completely into the optical field of camera
Until (Fig. 1 a).When control system (for example, electronic device that camera carries) identification QR code, control system makes cutting head
Stop with camera.For example, acquired QR code signal is sent instruction by the electronic device that camera carries and control calculates
Machine, and computer sends stop signal and receives stopping confirmation signal to cutting head and from cutting head.At that time, control system
100 obtain the position (for example, the space coordinate of optical axial 15 relative to system X, Y) of camera and the digitized map comprising QR code
Picture, and continue to handle it, so that it is determined that actual position of the spatial point 8 relative to system X, Y, and the point 8 obtains
It is taken as starting point.For this purpose, control system determines relative position (example of the spatial point 8 represented by QR code in digital picture
Such as, relative position of the spatial point 8 about the point for corresponding to optical axial 15 in the picture).In addition, by image QR code it is opposite
Size (for example, the diagonal line as QR code or pixel number as occupied by the side of QR code) is compared with known full-size(d)
Compared with to obtain the ratio (in another words, it is determined that the full-size(d) for corresponding to single pixel in image) of image.It, can by the data
To determine actual position of the starting point 8 relative to optical axial 15, and thus can determine starting point 8 relative to reference system X,
The actual position of Y.In addition, can determine the height of tissue layer from the data, and this is highly available for instruction cutting process step,
Such as constructing parameter, such as sharpening time of speed, frequency of oscillation or blade.
Then, camera rapidly, preferably along X-axis line moves, as far as the opposite apex (figure of cutting region 5
1b), preferably not snoop tag, and camera this time repeats again on the contrary towards the first vertex movements from this
State scanner program step, until the second label 26 QR code completely into the optical field of camera until (Fig. 1 c).Pass through
It completes above for program step described in the first label, it is determined that actual position of the second space point 9 about system X, Y,
And second space point 9 is retrieved as " point of alignment ".By this method, control system 100 obtains the direction of straight line 23, and therefore
Obtain the direction of the side 24 of tissue layer.The detection of above-mentioned example method can be used for being aligned and farthest since starting point
Label makes it possible to determine the orientation of tissue layer with possible maximal accuracy.
In short, have been determined starting point 8 actual position (and it is thus determined that the stacking 4 of sheet 3 or sheet position
Set), and by the point 9 of alignment determined in the cutting surfaces 2 of side 24 orientation (and it is thus determined that sheet 3 or
The orientation of the stacking 4 of sheet), position and true orientation of the tissue layer relative to system X, Y, and be proved to be and pass through control system
100 acquisitions.
At this point, control system is provided according to identified position and orientation automatic cutting tissue layer, preferably in order to obtain
The purpose (Fig. 3, Fig. 4 a and Fig. 4 b) of multiple shapes in predetermined cutting window 30.
Program step can be described in terms of according to predetermined position and direction positional dissection window.As described in
, statement " positional dissection window " is interpreted as in metaphoric meaning.Control system is held generally according to the cutting pattern of preloading
Row cutting process step, the cutting pattern of the preloading are adapted to such as previously determined positioning and orientation.
Fig. 3 shows such situation, wherein tissue layer is located on cutting surfaces, wherein side is parallel to axis X, Y simultaneously
And it is placed in the middle relative to cutting region.In this case, control system is positioned (example relative to starting point 8 to cutting window 30
Such as, the vertex of cutting window overlaps in starting point), and this is generally to make the fabric of tissue layer in entire cutting window enough
Extend on 30.
Fig. 4 A and Fig. 4 B show such situation, wherein tissue layer is located on cutting surfaces, wherein long side is not parallel
In X-axis line (as also shown in Fig. 1 a- Fig. 1 c).It should be noted that the clarity for description exaggerates in the figure
This is misaligned.In reality, by straight line 23 and side 24 be formed by angle be it is lesser, usually in the magnitude in several years.
In this case, the translational motion simple on cutting surfaces by cutting window, it is impossible to not moved in window
Window is positioned (as indicated by the ellipse of two dotted lines) in the case where more than tissue layer.Situation tend to
The advance (in the accompanying drawings to the left) of tissue layer and even worse is become for the cutting in subsequent cutting window.
By suitably circumgyration incision window 30, restores tissue layer and run through the state that entire cutting window extends, without
Centainly tissue layer is relocated.
Once cutting action is completed in the first cutting window, then sheet 3 or sheet stack and 4 usually advance (for example, by
Conveyer belt at cutting surfaces 2) suitable length, so that new fabric is located in cutting region 5 for subsequent cutting rank
Section.Preferably, locator step is executed again, the new orientation for snoop tag and for determining tissue layer 4.For
This purpose, it is preferable that after the advance of tissue layer 4, the spatial position as occupied by the point 9 of previous alignment is considered new
Starting point, preferably calculated by control system 100 without the use of detection system 6 (because the advance along X-axis line occur).Phase
Instead, system continues as described above to detect the label 20 near the opposite end of cutting region, and determines phase from it
The actual position for the spatial point answered.By this method, position and the orientation for having redefined the stacking 4 of part, according to its execution with
The cutting in cutting window afterwards.
