Brief description of the drawings
Technical scheme in order to illustrate the embodiments of the present invention more clearly, make required in being described below to embodiment
Accompanying drawing briefly describes：
Fig. 1 is the dimensional structure diagram of material centralising device one embodiment of the present invention；
Fig. 2 is the structural representation of the members of embodiment described in Fig. 1；
Fig. 3 is a kind of structural representation of sewing machine of the present invention.
Embodiment
Carried out below with reference to the design of embodiment and accompanying drawing to the present invention, concrete structure and caused technique effect clear
Chu, it is fully described by, to be completely understood by the purpose of the present invention, feature and effect.Obviously, described embodiment is this hair
Bright part of the embodiment, rather than whole embodiments, based on embodiments of the invention, those skilled in the art is not paying
Obtained other embodiment is put after creative work, belongs to the scope of protection of the invention.In addition, it is related in patent
All connection/annexations, not singly refer to component and directly connect, and refer to can according to specific implementation situation, by addition or
Couple auxiliary is reduced, to form more excellent draw bail.The orientation such as upper and lower, left and right involved by the present invention describe
For the mutual alignment relation of each part of the present invention in accompanying drawing.Each technical characteristic in the present invention, not
Being put after conflicting conflict can be with combination of interactions.
The present invention provides a kind of material centering method, and one of embodiment is as follows：
Clamping benchmark is determined on fixture, material first side is alignd with clamping benchmark after simultaneously clamping, determines one
The edge point of individual set point, the first position of fixture and material second side, set point are located at clamping benchmark corresponding material second
Side where side, for determining the second place of fixture；
Fixture is set to be moved to set point, when edge point reaches the position of set point, fixture stops movement, and now fixture arrives
Up to the second place, the displacement for recording the second place and fixture movement being calculated is L；Because error be present in the size of material,
Therefore the position of edge point is not fixed, so that difference of the position of the second place of fixture with the material size of its clamping
And it is different, therefore L is variable.
Fixture is withdrawn into 0.5L, stops movable clamp, completes the centering of the part material；
The material that above-mentioned centering is completed is taken away and carries out next step processing by feeding device, and fixture returns to first position, circulates
The clamping of above-mentioned material and the shift action of fixture so that in Manufacturing Automated process, centering can be carried out to every material respectively.
The present embodiment sets the first induction installation, is moved back and forth by motion track of first induction installation along fixture,
The first position of fixture is determined, specifically, origin plate is fixedly installed on fixture, the first induction installation is conventional sensing in place
Device, motion track of first induction installation along fixture is moved back and forth, stop moving when the first induction installation is reached at origin plate
It is dynamic, record the action origin of first position, as fixture that the position is fixture；Then the first induction installation position is fixed,
Fixture is acted again, during fixture do action, after often the centering of material of completion and material are removed, is returned to
The first position, repeats centering action, and whether in place fixture origin plate is identified by first induction installation, and one determines fixture
Whether the first position is reached.
In the present embodiment, set point is relative to the edge point of material second side further from clamping benchmark.At set point
Second induction installation is set, positioning presser feet, the positioning presser feet first end and the edge of material second flexibility are set at the edge point
Recline, so as to determine the edge point by the positioning presser feet, and be applied to various sizes of material, positioning presser feet second end
Motion track pass through set point, for coordinating the second induction installation to be sensed, the second induction installation is conventional biography in place
Sensor, for identifying whether the second end of positioning presser feet reaches set point.Material promotes the of the positioning presser feet when fixture moves
One end moves it, and the second end is moved to the second induction installation at set point.When positioning presser feet second end reaches set point
When, the second induction installation detects positioning presser feet in place, and fixture stops movement, and this position is the second place of fixture, due to not
There is error in the size with material, so the second place that fixture can reach every time is different.
When it is implemented, set point can be also disposed relative to edge point closer to the position of clamping benchmark, now press from both sides
The tool direction of motion in a first direction and above-described embodiment it is in opposite direction.
For various sizes of material, after the completion of clamping, its edge point position is different so that and specifically value is also different by L, from
And the value for withdrawing 0.5L also differs, this method continuously can carry out centering to different size materials, solve different size things
There is the technical problem that certain deviation causes to influence the sewing effect of later process in the center of material, so as to improve sewn product
Quality and production efficiency.
