Description of drawings
Reach in conjunction with the accompanying drawings by following nonrestrictive explanation, can more be expressly understood the present invention.
Fig. 1 is used to sew the schematic diagram of the present invention's machinery first embodiment of fabric structure;
Fig. 2 is used to sew the schematic diagram of the present invention's machinery second embodiment of fabric structure; With
Fig. 3 is the side view of the machinery among Fig. 2, and right hand portion illustrates the maximum puncture position of pin.
The specific embodiment
Fig. 1 and 2 illustrates two embodiments of machinery of the fabric structure on the plane that is used to sew.Certainly, be appreciated that the present invention only is not limited in making planar structure, the structure that coiling fibre sheet (fiber sheet) is made also constitutes application of present inventor, sheet or fabric can hoops and are helically twistedly formed flat stack circle, and sheet also can twist in and forming the stack circle on the axle.
Machinery generally includes " sewing " workbench 10, is used for supporting layer or sheet 12, and the length of this layer or sheet 12 and width depend on the final structure that produces.Feed in succession, thus be superimposed as continuous layer.Workbench is vertically set on below the sewing head 14, and this sewing head has the conventional belt pricker 18 of the quantification that is contained on the needle plate 16, the driving of one or more crank parts 20 that this sewing head drives by one or more motors, and vertically live reciprocating cutter.The stripper 22 that is fixed to the frame 24 of machinery is installed on the sewing work platform, prevents that fabric structure from deforming when pin lifts.Certainly, workbench and stripper all are installed with hole 26,28 respectively, are used to make pin to pass through.Workbench vertical motion under the driving of the device of for example forming 30 by motor-driven worm screw.Two groups of driven rollers 32,34 (being also referred to as the entrance and exit compressing member) are arranged on the upstream and downstream of machinery, are used for flatly carrying fabric structure towards sewing head.
The present invention is furnished with device 36, is used to measure fabric structure top surface position, and is arranged in sewing head 14, so that determine when the low spot of maximum puncture the actual paracentesis depth of pin in fabric structure.Because the stroke of pin is constant with respect to its frame that is connected to, and because the relative frame of sewing work platform is arranged on known distance, therefore can demonstrate easily, the degree of depth of pin puncture textile material is directly dependent on the thickness of the sewing work platform and the material between the top surface of surveying.
For this purpose, measurement mechanism 36 is fixed in frame 24, and needle plate 16 (with stripper 22) is drilled with hole 38 and 40, so that measurement mechanism can match with the top surface of fabric structure.
In the illustrated embodiment, this cooperation contactlessly (position of remote metering fabric structure top surface) or have and (mechanical detector is reduced to the top surface of fabric structure) contiguously and carries out.
Fig. 1 illustrates a preferred embodiment of the present invention, and wherein the noncontacting measurement device is made up of the optical measurement assembly, as generating laser/receiver 42.Transmitter sends a laser beam, passes needle plate and stripper, and towards the top surface of fabric structure, top surface arrives receiver with beam reflection then.Suppose that distance between transmitter and the sewing work platform is known to the preceding first measurement, therefore the distance between transmitter and the fabric structure top surface can be determined by analyzing the laser beam go and return path, is enough to make exactly the thickness of the fabric structure that the sewing work platform supported.In addition, for avoiding the problem of obvious defects on the fabric structure, the preferred angle pencil of ray type of laser module (because the laser of the type has comprehensive function by the measurement on the whole width of light beam).Certainly, can use fully to be operated in ultrared optical measurement assembly, but not be essential preferred infrared ray.
Fig. 2 illustrates an optional embodiment, wherein, measurement mechanism is made up of the mechanical detector that the inner plunger 44 that is fixed to frame 24 forms, and outer sleeve 46 is slidably mounted on it, sleeve has a slightly end of circle, is used for directly contact fabric structure (after by needle plate and stripper).The slip of sleeve is sprayed controllably from the control module 48 that is fixed to frame 24 by the fluid that is preferably Compressed Gas and to be advanced piston, and is driven.The pressure of fluid is adjusted into the function of the characteristic (hardness, elastic reaction) of fabric structure, and it is adjusted to guarantee that sleeve does not bounce on described fabric structure.Sleeve also is included in the reflection collar 50 on its top, is used for and the optical measurement assembly that is fixed on frame 24 equally, matches as laser or RF transmitter/receiver 52.Transmitter is with the collar of light beam directive sleeve, and light is again by its reflected back receiver.When the end of detector contacts with the sewing work platform, suppose that distance between transmitter and the receiver is known to the previous measurement, therefore, determine the distance (by analyzing the light beam go and return path) between transmitter and the receiver when contacting with the top surface of fabric structure, in this case, also be enough to make exactly the thickness of the fabric structure that the sewing work platform supported in described end.
In above-mentioned two embodiments, measurement mechanism 36 preferably is arranged in the midplane of sewing head 14, the direction (although certainly far leaving from it) of advancing perpendicular to fabric structure.If the form of fabric structure is two adjacent sheets that advance under sewing head parallel to each other, then measurement mechanism is paired.In structure shown in Figure 3, sewing head can comprise two independently needle plates that are arranged side by side, and has to be substantially disposed in the middle measurement mechanism of each sheet subsequently.For ease of understanding, Fig. 3 illustrates the machinery in the above optional embodiment, two different positions, a position (left side of Fig. 3 is half of) corresponds to the resting position that a syringe needle lifts, and another (right-hand component) corresponds to the low dot location of described head in the maximum puncture of its pin.
The low spot of the maximum puncture of pin is determining that by the sensor 54 of for example induction or optical type sensor is fixed on frame in real time, matches with a specific flank of cam 56 on the crank assemblies 20 for example, thus the up-and-down movement of control sewing head.This flank of cam is used for determining that a period of time (being not only an independent transient measurement moment) is in the down stroke process of needle plate, preferably near low spot, measurement mechanism 36 work in this process, can obtain several measured values, the processor module 58 that is connected to sensor 54 and measurement mechanism 36 is determined first mean value of a sewing layer according to these measured values.These are measured subsequently after the step of advancing of each level of fabric structure and carry out repeatedly, be used for determining the actual average paracentesis depth of pin at this class value of given channel end acquisition, on this basis, the device 30 that is used to drive the sewing work platform and be connected to processor device 58 can automatically make the work vertical motion to hold following passage, the size of the downward step of workbench is controlled, so that the distance that pin punctures in fabric structure and determines.
Therefore, the bind that machinery of the present invention carried out is summarized as follows.Beginning, second thickness is superimposed upon on the ground floor thickness that is arranged on the sewing work platform, and these two layers of the method stack are sewed head under predetermined condition barbed pin combines.Thereafter, the sewing work platform moves a distance relative to sewing head, and this distance is confirmed as the function with suitable measurement mechanism, the two superimposed layer surface locations that record at the low spot place of maximum puncture.At last, the threeply degree superpose aforementioned two-layer on, described threeply degree is incorporated into aforementioned two-layer under identical predetermined condition.Subsequently, for the layer of back, these steps repeat, till fabric structure reaches desirable thickness.
The method of using in above-mentioned machinery comprises: at first, with one or two stack the layer be put on the workbench 10, then, use needle plate 16, utilize driven roller 32,34 to make fabric structure horizontal ground motion on whole width simultaneously, each layer combined by sewing.Then, workbench descends with the mobile step of determining size, thereby the 3rd layer can be applied, and is sewn into two-layerly in addition successively, and proceeds till obtaining desirable thickness.
In the present invention, the mobile step that size is determined is not constant, do not concern according to predetermined down yet, but by in the above-mentioned layer of pin at fabric structure of the low point measurement of the maximum puncture of pin actual paracentesis depth determined, thereby obtain the sewing density of the desirable reality of described fabric structure, density is constant, perhaps can be with the varied in thickness of fabric structure.Therefore, the position of described fabric structure top surface is measured in the centre of pin, thereby produces the size of the downward step of sewing work platform, so that pin is to determine distance puncture fabric structure.
