Then, the carrying device 120 to sheet metal feedway E describes.

Shown in Fig. 8, Figure 11 121 expression propelling for sheet metal 103 engagings that link to each other with the band shape that is arranged in path of navigation 110 send parts.Send parts 121 and main part 122 reciprocal rotations are pivotally mounted on the driving body 133 of sending driving mechanism 130 freely, have the arm 125 of L word shape endways by pivot 122a.On the arm 125 126 expression is used for the holding section that engages with the hole 106 of sheet metal 103.Holding section 126 makes holding section 126 break away from from the hole 106 of sheet metal for when sending parts 121 and retreat (dextrad to Fig. 8, Figure 11 moves), is the end tilts face 127 of oblique shape and form rear side (right side of Fig. 8, Figure 11).128 expressions are used for sending the spring of parts 121 towards the below application of force.

Then, 130 in carrying device expression is used to make sends the driving mechanism of sending that parts 121 move back and forth on fore-and-aft direction (left and right directions of Fig. 6～Fig. 8).Send driving mechanism 130 and comprise the parts of representing by Reference numeral 131～138.Two post parts (being also referred to as piece) that 131 expressions are fixing with respect to the bottom 100b of body frame 100,132 expressions are bearing in the bar between two post parts 131,131,133 expressions move back and forth the driving body of installing freely (being also referred to as slide block) on fore-and-aft direction with respect to bar 132,132,136a represents the driving shaft of stepper motor 136,137 expressions are installed in the arm on the driving shaft 136a, the connecting rod of 138 expression armites 137 and driving body 133.Send driving mechanism 130 via arm 137, connecting rod 138, driving body 133, the reciprocal rotational motion of driving shaft 136a is delivered to the form of front and back motion sends parts 121.

Above-mentioned sheet metal feedway E makes carrying device action as well-known, and the terminal 103a of the sheet metal 103 that the band shape that is positioned at path of navigation 110 links to each other is given prominence to towards outstanding space 118 from feed point 111.Carry out this action repeatedly, and lamellule 104 is constantly supplied with to outstanding space 118.Situation to this action at length describes.

If make carrying device action, and make and send parts 121 and advance, then under the holding section 126 of arm 125 and state that the hole 106 of sheet metal 103 engages, sheet metal 103 is advanced along arrow 150 directions along arrow shown in Figure 11 150 directions.And, make the terminal 103a of sheet metal 103 give prominence to (with reference to the position of Figure 11 (A)) towards the outstanding space 118 that is arranged in needle falling hole 2 tops by single-point line expression from feed point 111.

Then, if send parts 121 and retreat along arrow 151 directions shown in Figure 11 (B), then the end tilts face 127 of arm 125 is met on the peritreme 106a in hole 106 of sheet metal 103, and holding section 126 is lifted.Holding section 126 only retreats the distance of a pitch that is equivalent to sheet metal 103.Carry out such action repeatedly, the terminal 103a that is present in the sheet metal 103 of path of navigation 110 constantly gives prominence to towards the outstanding space 118 that exists previously of feed point 111 and gets final product.In addition, this action gets final product shank, embroidery tambour F synchronously (relevant action as shown in figure 13).

In addition, the pitch (sendout) that carrying device is sent sheet metal 103 is sent the number of steps of the stepper motor 136 of driving mechanism 130 and can be set as well-known by control.And then, as Figure 10, shown in Figure 11, use known adjustment component 140 (parts) adjustment to send moving forward and backward of parts 121 and get final product with parts 140a, 140b.

Then, in Figure 13, represent pin, pressing cloth piece, embroidery tambour F, shank switching mechanism, send the state of the relevant action of driving mechanism 130, sheet metal etc.Their action can be carried out by the computer control that control device H carries out as well-known.

The device that uses above-mentioned formation is described (in addition, about embroidery machine C and sheet metal feedway E action separately, with reference to above-mentioned record) with the action that lamellule 104 is stitched on the cloth G.

At first as shown in Figure 5, make the above-mentioned sheet metal feedway E that is arranged on the extended line 13 by track 107 coincidences make carrying device (with reference to Figure 11) 120 actions that self have, and the terminal 103a of the banded sheet metal that links to each other is given prominence to towards outstanding space 118 from feed point 111.

Thus, shown in Figure 11 (A), the end 103 of above-mentioned sheet metal is overlapped above the needle falling hole position 2 of embroidery machine C.

In these cases, make from feed point 111 towards the motion track 107 in the hole 106 of the lamellule 104 of needle falling hole 2 directions with the rotary middle point 11 of above-mentioned shank retainer is consistent with the extended line 13 of the tie line of needle falling hole position 2, thereby as clear, the size W1 between the both sides of pressure fabric component 37 can be made as narrowlyer identical with the width dimensions W1 in the outside of two cloth-pressing claws 39 from Figure 12 (D).

Therefore, the space that pressure fabric component 37 is set when implementing exists under the situation more than needed, even the error about motion track 107 is spent with respect to the angle existence ± 10 of extended line 13 also can be allowed.This be because, if the error of this degree, even then the cloth-pressing claw 39 of pressure fabric component 37 towards parallel with motion track 107, be benchmark with extended line 13, the width dimensions W1 in the outside of the size W1 between the both sides of pressure fabric component 37 and two cloth-pressing claws 39 also can create a difference hardly.

In addition, under the situation that above-mentioned motion track 107 tilts significantly with respect to above-mentioned extended line 13, need make pressure fabric component 37 peristome 40a towards shown in the double dot dash line of Figure 12 (D) like that, the motion track 107a with from oblique supply sheet metal 103 time is corresponding.So, be benchmark with extended line 13, it is bigger than the size W1 between the both sides of compress parts 37 that the size W2 between the both sides of pressure fabric component 37 becomes.

Like this, make pressure fabric component 37 under the situation corresponding with above-mentioned oblique motion track 107a, the worry that generation can not be configured with

compress part

37a, 37a to each other replaceably in the seam embroidery of a plurality of arrangement settings of Figure 12 (A).

Then, if the shank of above-mentioned embroidery machine C and pressing cloth piece are descended along arrow 152 directions, then shown in Figure 11 (B), the drive division 116b of pin fixed part 17 presses the cut-out parts along arrow 152 directions, and needle point is connected, and the outstanding lamellule 104 of the sheet metal 103 that band shape is continuous cuts, the hole 106 of lamellule is overlapped with needle falling hole 2, and then the pin of installing on the shank arrive bottom dead centre, make suture 63 interweave and rise with rolling off the production line, lamellule 104 seams are solid.

In that being risen, will sting this shank when extracting through the pin in the hole 106 of lamellule 104, pressing cloth piece descended in the moment shown in Figure 13, as shown in figure 12, push securely at its compress face of pressure fabric component 37 usefulness 39a of pressing cloth piece under the state of cloth G of both sides of lamellule 104, pin is extracted from cloth G and is risen.Like this, if the both sides of cloth G are pressed, then cloth G can " play " and become stable, and the position of the lamellule 104 of the upper surface of cloth G is also stable, being under the state that sews up the position with respect to cloth G predetermined, sews up.

Then, as shown in figure 13, pressing cloth piece also begins to rise, and then embroidery tambour F moves.

Then, shown in the 2nd pin of Figure 13, under the situation of the carrying device action that does not make sheet metal feedway E, shank, pressing cloth piece, embroidery tambour F are made synchronously.Thus, in the 2nd pin, line can not pierce through the hole of sheet metal 103, but the sheet metal 103 of crossing the upper surface of cloth G directly is inserted in the cloth, and is with respect to cloth that lamellule 104 is fixing.

Carry out such action repeatedly, make embroidery machine C and sheet metal feedway E synchronously and knee-action, sheet metal is sewed up get final product.

In addition, though in Figure 13, illustrate per two pins with regard to thorn through in the hole of sheet metal 103 and situation about sewing up, but also each pin just stings through in the hole of sheet metal 103 and sew up.

Then, to expression and the pressing cloth piece 37 of Fig. 1～Figure 12 Figure 14 that has different examples aspect the pressure fabric component (A) (B) (C) describe.Figure 14 (A) (B) pressure fabric component of (C) in order more stably to be provided with by compress F.

In addition, at Figure 14 (A) (B) in (C),, on the Reference numeral identical, add alphabetical g and the repetitive description thereof will be omitted with above-mentioned Fig. 1～Figure 12 for the identical or impartial part of thinking among function, character or feature etc. and above-mentioned Fig. 1～Figure 12 of part.

As shown in figure 14, plan view shape about the pressure fabric component 37g of pressing cloth piece 36g, for can be under the decline state, push the cloth G of the both sides of above-mentioned lamellule 104g with compress face 39ag, and from the root 38g of pressure fabric component forwards (below of Figure 14 (A)) with two cloth-pressing claw 39g respectively towards the two side-prominent settings of above-mentioned lamellule 104g.And then (top of Figure 14 (A)) is outstanding towards the rear that two cloth-pressing claw 39g are set from root 38g respectively, increases with respect to the press surface of cloth, and plan view shape forms the H type.Therefore, if can from Figure 14 (A) (B) (C) understand like that, the compress face 39ag of available H type presses the upper surface of compress G securely, so the advantage that can make cloth G under the state of more stably pushing is arranged.

In addition, the pressure fabric component 37g shown in Figure 14 (C) represents to have the example of pin by hole 41bg.

Then, Figure 14 (D) of example that the expression disassembling, assembling and replacing is provided with pressure fabric component 37 (perhaps pressing part 37a), 37g and the attaching parts 43 of pressing cloth piece freely describes.Pressure fabric component (can be Reference numeral 37, the pressure fabric component of 37g mark or any of pressing part 37a) and attaching parts 43 form with minute body component, and disassembling, assembling and replacing is linking freely.The formation of this linking part uses known formation to get final product.For example, can constitute, the female threaded hole that 42 tops that are illustrated in pressure fabric component 37 (perhaps pressing part 37a), 37g form, the open-work that 48 bottoms that are illustrated in attaching parts 43 form, 49 expressions are inserted and to be led in through hole 48, combine with female threaded hole 42 screw threads and the screw element that is used for pressure fabric component 37 (perhaps pressing part 37a), 37g and attaching parts 43 are linked integratedly.

If disassembling, assembling and replacing constitutes freely like this, then can easily change the pressure fabric component that adds the pressing cloth piece that is provided with on the shank.

Therefore, for a plurality of pressing cloth pieces that are set up in parallel, can at random change sheet metal with respect to the pressing cloth piece that is positioned at its position and sew up the pressing cloth piece of usefulness or the pressing cloth piece of seam embroidery usefulness, can be as required, shank in the many shanks that are set up in parallel, that be positioned at certain position at random is chosen as sheet metal sews up usefulness, and making middle use.
