[patent documentation 1] spy opens the 2004-24843 communique
According to the prior art, has the advantage that to adjust the compress height of many heads at a place of embroidery machine together.But when manually adjusting, when the processing conditions of embroidery decorative pattern changed, adjusting the compress height can be pretty troublesome, has this to adjust problem slowly.In addition, when adjusting automatically, because the timing of the adjustment compress height that is enrolled in the embroidery data is only thick based on cloth, so, after the speed of service of embroidery machine changes, producing the compress height when excessive and not enough, existing and process that cloth is touched (ば つ く) or in a class problem of processing residual impression on the cloth.The present inventor thinks that after deliberation the compress height of the thick adjustment of corresponding cloth under being fit to the situation of speed of service when low, seems not enough when the speed of service is high, and the mobile of processing cloth impacted or residual impression on processing cloth.Otherwise, under the situation of the compress height of the thick adjustment of corresponding cloth when the suitable speed of service is high, when the speed of service is low, seem excessive, the phenomenon that exists processing cloth to touch.
Summary of the invention
The objective of the invention is in order to address the above problem, providing a kind of can revise the height of compress pin automatically soon and carry out optimum multi-head embroidery machine corresponding to the speed of service of embroidery machine.
For overcoming the above problems, multi-head embroidery machine of the present invention has the guiding mechanism corresponding to the height of the compress pin of processing cloth thickness adjustment bottom dead center position on many heads.This embroidery machine has connecting axle, actuator and control device.This connecting axle connects the described guiding mechanism of each head; This actuator drives described connecting axle; This control device is by controlling the height that described actuator is revised described compress pin corresponding to the rotating speed of machine shaft.
At this, as guiding mechanism, be not limited to specific mechanism, preferably adopt the mechanism that separates with the power-transmission system of machine shaft, like this, can be at the multi-head embroidery machine compress height of adjusting at any time in service.Actuator as making the guiding mechanism action for example can use motor such as pulse motor or stepper motor, perhaps fluid-pressure cylinder such as cylinder or oil hydraulic cylinder.As the rotating speed (speed of mainshaft) of machine shaft, can utilize the rotating speed detected value of machine shaft or spindle drive motor, perhaps predefined speed of mainshaft information in embroidery decorative pattern data.
The correction of being undertaken by control device makes the compress height of the thick adjustment of corresponding cloth relatively low when the speed of mainshaft is low in principle, makes it higher relatively when the speed of mainshaft is high, but also can make it opposite according to the kind of cloth.There is no particular limitation for the method for corresponding speed of mainshaft change compress height when this is revised, and for example can adopt any mode of straight line increase and decrease, curve increase and decrease or stage increase and decrease.
In addition, the described control device of multi-head embroidery machine of the present invention has display part, input part and control part.This display part shows that on picture the pin in the embroidery decorative pattern data counts information; This input part is counted the relevant processing cloth thickness of information by operating personnel's input with pin; This control part is corresponding to the rotating speed control actuator of processing cloth thickness of being imported and machine shaft.
At this, as count information at display part with the pin that picture shows, can enumerate the pin number that for example begins to make, at beginning and the pin number of termination, the pin number when stopping to change color etc. of processing cloth varied in thickness scope.The thickness of the processing cloth of operating personnel input is the whole thickness of working position, is the thickness of a slice processing cloth in the place that a slice processing cloth is arranged, overlapping two or more the place of multi-disc processing cloth be this overlapping thickness.
Control part is the described compress height of corresponding speed of mainshaft control actuator correction when thick control actuator is adjusted the compress height corresponding to the cloth of being imported.In the latter's correction, can increase and decrease the compress height continuously along with the increase and decrease of the speed of mainshaft, also can be when the rotating speed amplitude (for example 100 rev/mins) of the every increase and decrease of speed of mainshaft regulation (for example 0.03～0.15mm/100 changes) increase and decrease compress height stage by stage.
The concrete modification method that is undertaken by control part is not particularly limited, and for example can add that the correction value of corresponding speed of mainshaft increase and decrease is carried out by the thickness input value at cloth.The setting of correction value can be imported with the speed of mainshaft on the picture of display part explicitly by operating personnel, also can be in memory the correlation graph of the typing speed of mainshaft and correction value.If like this, just can when the embroidery machine low cruise, revise the compress height of the thick adjustment of corresponding cloth relatively lowly, suppress touching of processing cloth; When the embroidery machine high-speed cruising, revise the compress height of the thick adjustment of corresponding cloth relatively than the highland, to prevent to process the impression of cloth.
In addition, multi-head embroidery machine of the present invention is set up the display that shows the current height of compress pin on actuator.As display, preferably use mechanical type display with actuator output interlock.For example, display board is fixed on the housing of actuator, the scale of the currency that shows the compress height is set on display board, the pointer of display scale is installed on the output shaft of actuator.
According to multi-head embroidery machine of the present invention, owing to drive the guiding mechanism that is located on many heads together with actuator, corresponding to the rotating speed of machine shaft control actuator, like this, obtained the good result that the speed of service of corresponding embroidery machine can the fast automatic correction compress pin height in optimization ground.

Then, operating personnel push cursor movement key 65, are setting moving cursor 69 on the picture 68, and by pressing or enter key 66 down, it is thick that input and pin are counted the relevant cloth of information, pushes definite key 67, in storage part 62 setting pin number and the thick relevant informations of cloth.As shown in Figure 6, when pushing another mode switching key 64, display part 61 shows the thick correction picture 70 of cloth.Be provided with the stage at this picture 70 and represent the zone of the speed of mainshaft and the zone of the thick correction value of cloth of the corresponding speed of mainshaft of expression.Operating personnel by with same operation when thick of input cloth, import the cloth thick correction value relevant with the speed of mainshaft, these relevant informations are set in storage part 62.Illustrated example is represented such example,, when the speed of mainshaft is 0～300 rev/min the thick correction value of cloth is set at 0mm that is, makes the thick correction value stage ground of cloth increase 0.1mm during 100 rev/mins of after this every increases, imports.
In addition, the thick input value of cloth that control panel 8 is set at the storage part 62 that reads out in operation board 7 in service of embroidery machine 1, simultaneously, based on the speed of mainshaft information of counting the information related setting in advance with pin in the rotating speed detected value of machine shaft or spindle drive motor or the decorative pattern data of embroidering, read the thick correction value of cloth in the storage part 62 that is set in operation board 7, by adding that in the thick input value of cloth the thick correction value of cloth controls actuator 45, the height of the compress pin of bottom dead center position is adjusted and revised.
Below, the action of multi-head embroidery machine 1 as constituted above is described.Add man-hour in the embroidery of carrying out various sewingss, to set cloth relatively thick with the pin number on the thick setting picture 68 of cloth at first as described above for operating personnel, sets correction value relatively with the speed of mainshaft on the thick correction picture 70 of cloth.Then, the embroidery decorative pattern data after the renewal that contains these set informations are logined storage part 62, starting embroidery machine 1, processing begins to embroider.In service at embroidery machine 1, as described above, control panel 8 is based on set information control actuator 45, and guiding mechanism 43 is as Fig. 7, action as shown in Figure 8 in each head 3.
Fig. 7, Fig. 8 are illustrated in processing cloth and carry out the action that embossing adds the guiding mechanism 43 in man-hour.In this processing example, on processing cloth W, there is not the pin number interval that begins to make (Fig. 5: 0～199 pin) set the little cloth thick (1.0mm) that has only processing cloth W of embossing sheet Wa; The big cloth thick (3.0mm) that pin number interval (200～299 pin) in the way is set the thickness of attach most importance to stack worker cloth W and embossing sheet Wa for of making that on processing cloth W, has embossing sheet Wa.At this set condition, starting is during embroidery machine 1, and as shown in Figure 7, with the low-angle axle 40 that is rotationally connected, cam 41 makes guiding parts 32 remain on low position via lever 36 to the interval actuator 45 that begins to make at processing cloth W from origin position.
At this state, when lifting body 22 descended, connecting rod 29 was with the angular bend of the height of corresponding gathering sill 31, at the stroke lower end position of slide mass 27, arm 28 is hung the needle bar hoop 18 that stops on the compress rod 12, and compress pin 14 is dropped to and the suitable height of processing cloth W thickness at its bottom dead center position.Like this, the currency of the compress height H 1 of this bottom dead center position is shown on the display board 56 of display 46 by pointer 57.At this, when being decided to be low-speed running interval (for example the speed of mainshaft is 0～300 rev/min interval) in the interval that this is begun to make, because the thick correction value of cloth is made as " 0mm " (with reference to Fig. 6), so compress height H 1 becomes the 1mm as the thick input value of cloth.Like this, because the correction of compress height H 1 by the corresponding speed of mainshaft becomes suitable, so can not produce touching of (causing during the compress excessive height) processing cloth W.In addition,, confirm the indicated value of display 46, can easily set suitable compress height again by operation board 7 even when this compress height is improper.
In addition, making the pin number interval that has embossing sheet Wa, as shown in Figure 8, actuator 45 makes connecting axle 40 rotate with wide-angle, and cam 41 makes guiding parts 32 remain on high position via lever 36.Like this, be accompanied by the decline of lifting body 22, connecting rod 29 is with the wide-angle bending, and the stroke of slide mass 27 dwindles, compress pin 14 drops to the height of the overlapping thickness that is equivalent to process cloth W and embossing sheet Wa at its bottom dead center position, shows the compress height H 2 of these bottom dead center positions at display 46.At this, making the interval that has this embossing sheet Wa when being decided to be high-speed cruising interval (for example the speed of mainshaft is 701～800 rev/mins interval), in this interval because the thick correction value of cloth is set at " 0.5mm " (with reference to Fig. 6), the 3.5mm that obtains so compress height H 1 becomes that 3mm as the thick input value of cloth adds the thick correction value 0.5mm of cloth.Like this, because the correction of compress height H 1 by the corresponding speed of mainshaft becomes suitable, so, also can not give mobile bringing (the compress height the causes when not enough) influence of processing cloth W or residual impression on processing cloth even when high-speed cruising.Like this, at whole service speed interval from low speed to high speed, can corresponding each speed of service be not have too high and not enough optimum height with the compress height correction automatically, apace.
In addition, counting which interval in the scope at whole pin, to get the great speed of mainshaft be arbitrarily, for example in above-mentioned example, also can be decided to be the low cruise interval making the interval that has embossing sheet Wa.
The invention is not restricted to described embodiment, for example can be as described below, in the scope that does not break away from aim of the present invention, can suitably change and it is specialized.
(1) can constitute, show relatively that at the display part 61 of operation board 7 pin in the embroidery decorative pattern data counts information and speed of mainshaft information, in a picture, set thick input value and the correction value of cloth.
