Description of the Invention: [Technical Field of the Invention] The present invention relates to a quotation of a corpse of a corpus of a patent application, and a tenter frame of a citation of a term (tenter) Spannrahmen, English: tenter frame or stenter. [Prior Art] According to Fried Sch6ner and Kius Freier's book "embroidery technology" (veb Science and Technology Publishing House, Leipzig, 1982, (4), embroidery machines can be classified according to different viewpoints: - The classification is for the number of line systems involved in the embroidery process: in the case of some machines, embroidery is only produced with a one-line system, and the machine requires two line systems, that is, another second line is required: the lower line, the rear Line, line axis 'snake line, or yarn tube line (10) (6) is like, English: secret ^ thread). The second classification is for the number of needles that work at the same time: examples of single-needle embroidery machines are (4), A., and crank embroidery machines. The multi-needle or proportional lancet machine (RaPPirtStiekma Sehlne) is a shuttle type slinger and a hand screaming machine. In addition to these two groups, there are also multi-head embroidery machines, which are not in the above two groups. The principle of this machine is to install 3, 4, 6, 1G or 12 embroidery heads into a large private rainbow. _ , . On the board, some embroidery heads use a common drive

The simultaneous operation of the M m i P battles thus achieved is necessary to enable all the needles to simultaneously pierce the embroidered base fabric (stickboden or stichgut, English: gr〇Und) or simultaneously from the piercing base fabric. Here, the thorn and embroidered base fabric can be individually sandwiched in the embroidery frame ϋ 3 201114970 (SUckrahmen, English: embroidery frame). These embroidery frames are screwed to a structure like a creel, which is controlled by a small automatic device (Antomat) at the horizontal. In the embroidery automatic machine with six heads, the embroidery field area is about 24〇x24〇mn^, the embroidery forming το pieces and the procedure for forming the embroidery are the same as those of the singer embroidery machine, and the only difference with the latter is that in the above various settings A cloth press that holds the embroidered base fabric firmly when embroidering. If the embroidery frame moves further, the presser is often raised. In addition, individual embroidery heads typically have a line monitoring system that automatically turns off the machine when the line is broken. The first multi-head embroidery machine was sold by De Singer sewing machine 100 years ago (see The Art of Embroidery, Coleman, Schneider, 1991). The first automatic multi-head embroidery machine was launched in 1927 (also known as "Wi^kei-Automat"). Further literature can be found in general textbook technology and production engineering" Klaus Freier, VEB Science & Technology Publishing House, Yebishi, 130 ~13 1 page". SUMMARY OF THE INVENTION The present invention relates to the above-described multi-head embroidery sewing machine in which each embroidery head is provided with a plurality of types of positions. Hereinafter, in order to clearly distinguish the same, the multi-head embroidery sewing machine is also referred to as a "multi-head multi-needle embroidery machine". Here, in general, each needle position has a line monitor (set as needed), a wire guide (dry punch in the literature), and the wire guide device includes a wire tensioning position for compensating the stitches (on-line) And a needle provided on a needle pusher (Nadelstbssel) which can be moved up and down and driven by a drive unit. The above-mentioned shape 201114970 The component of the stitching is supported by the embroidery head of the head embroidery machine on a support arm i, and can be moved laterally. Below each of the thorns, there is a stitch board (needle board), and a pinhole is provided in the stitch board for inserting a needle, and the stitch board defines the position of the embroidery position. Each of the needles of an embroidery head can move laterally to the embroidery position, and in operation, the embroidery base fabric (which is stretched over a tent frame movable in the X direction and the y direction) rests on the embroidery position . The needles in the embroidered position pass through the embroidery base cloth into the pinholes as the needle moves. Here, the upper thread passes through the embroidery base fabric and uses the associated needle movement to form a loop on the back side of the embroidery base fabric (Schlauf, 00p). Then wear the lower thread: this loop. When the needle is pulled back, the upper thread is pulled and formed in the embroidery base fabric - a so-called stitch (stitch, stitch) (stich, English: stitch). During embroidery, only one needle position for each needle position is active, that is, the needle position at the embroidery position. The embroidery heads of the above-described multi-head embroidery machine are arranged in a conventional manner along a carrier arm in a specific ratio. Therefore, one of the features of these multi-head multi-needle embroidery sewing machines is that each embroidery head has a plurality of needle positions. This has the advantage that another line can be placed at each needle position, so that multi-color embroidery can be done, and often only the relevant needle is in motion. A needle pusher of a needle set and its associated wire rod are generally supported in a carrier which, by movement, brings the selected needle bar and each of its associated wire rods to a positionally fixed manner The front of the drive, the line is replaced. f For example - Muguo 1 and Figure z Dinghu Xiaoyi Lidu multi-headed acupuncture and embroidering machine "It contains a rack (Xie), a screaming platform on the rack (10)) (203), and most embroidery heads (2〇5) [they are arranged in a row above the embroidery table], 201114970 As shown in Fig. 2, each embroidery head (2G5) has several needle positions each having a needle (2i5) Here, the needle position includes a fixed wire guide member (10) or a wire stop g (four) wire take-up lever or wire guide (209), and a wire steering finger (21 1), and a pin (2). 5) [The needle is placed on a needle (2U) with a needle pusher (7) 4]. (4) 2 In addition, each needle pusher (214) is provided with a - presser (1) 7), and an embroidery frame (219) is provided below the embroidery head (10), and the spunlace fabric to be embroidered can be placed in the hedgehog frame. The thorn _ 〇 3) can be placed in a large tent frame (9)) 'The clamping frame extends over the embroidery lift (the dog's width range ° the tenter frame (221) can be moved in the X and y directions in a conventional manner. The embroidery head is arranged on the linear guide (223) and can be moved along the X direction along the guide. The conventional multi-needle embroidery sewing machine comprises two time-keeping components arranged at a distance from each other. Can be fixed between them. To lose the cloth (this is also called "the bottom cloth" in the stroke. This cloth must be clamped and sweetened into the edge of the thorn end. The edge is also clamped and clamped. People. _, the embroidery sewing machine is provided with a clamping frame 'the size of its space metric (= y direction) is about 150 cm ~ 180 cm. The entire clamping frame can use the conventional guiding device and drive 2 along the X direction And the y-direction movement '俾 can be used to make the entire area of the thorn. The bottom of the embroidery head is provided by the small bobbin (Spulehen), which is in the shell - as used in traditional sewing machines. , : Winding up to (10) meters of line 'This will make a rush in the multi-head seam: The small spool is replaced more frequently. If the line reserve is replaced托 surplus and small spools to be 6 201114970 The shortcoming of this conventional multi-head multi-needle embroidery sewing machine is that its space requirement is large, equivalent to twice the depth of the tenter frame (y direction) ^ such a large tenter frame itself There is also a disadvantage. "When the machine is in operation, the small spool with the lower thread is not easy to find. It is often necessary to replace the small spool, and people have to climb under the tent frame, and can get the small spool' or when the upper thread breaks to be repaired. It has to climb to the machine. Therefore, the large tenter frame is greatly hindered during the maintenance of the embroidery machine. DE-A-3720907 published a shuttle embroidery machine with two fabrics arranged up and down. Here, The fabric is wound on the cloth shaft, and the cloth shaft is supported on the embroidery frame of the machine. The upper cloth shaft and the lower cloth shaft are selectively driven by an endless belt and driven by a motor drive shaft to drive the cloth by the motor. The shaft is rotated to individually "roll onto the shaft" (Aufwellen, English: wind_up 〇nt〇shaft) or synchronously "continue to take over" [Nachweiien, English: further (after) wind]. a reversible "belt clamping rod" (it Provided on the free end of the drive shaft) can selectively move the upper belt or the lower belt' so that the cloth can be transported forward or backward. It is not mentioned in dE_a_3720907: Tightening or how to continue to be wound onto the shaft in the clamped state. European patent ΕΡ-Α-0 148 127 published a creel for large embroidery machines (Gatter, English: creel), in which the cloth shaft is utilized The pulling means are connected to each other and the cloth shaft is kept rotatable only in the unclamped state. A motor which is freely movable relative to the creel is used as a driver to clamp the embroidery backing which is taken up onto the cloth shaft. The sides have a tooth structure in the form of a crown gear. = Klinke (English: detent) (it is fixed in a sturdy way) embedded in the crown gear. When the cloth is slack, the rear end of the rafter is contiguous with a plate, such as 201114970. The detachment of the shank is disengaged from the tooth structure, and the disadvantage of the cloth yoke is that the cymbal rotates when clamped. This type of cylinder does not continue to be re-rolled when it is tight, and the motor of μ at 1 will limit the range of motion of the movement.

Advantageous further features of the tenter frame are found in the accompanying 1 'the tenter frame of the invention has the advantage that it can be embroidered longer than the fabric embroidered with a conventional tenter frame (more than the multi-headed needle-punching machine used so far) A fabric that reaches a longer length). Embodiments of the present invention are exemplified below by way of drawings. [Embodiment] The tenter frame (11) of the embroidered base fabric shown in Fig. 3 has two cloth shafts (13), (15) which are rotatably provided on the side portions (17). A profiled recess (10)' extends around the shaft in the axial direction, and a clamped rib (not shown) can be placed therein. Here, the edge of the embroidery base fabric can be clamped between the clamping rib and the contour recess ( 11) on 11 201114970. The tenter frame (11) is particularly used with a multi-needle multi-needle embroidery sewing machine whose conventional tenter frame has not been able to allow the embroidered base fabric to continue to be re-wound. For this reason, most of the conventional tenter frames have a depth of 〇5〇cm, and the enamel can also embroider the large embroidered base fabric. The depth of the tent frame (1) of the present invention is less than: and is less than 100 cm, particularly preferably about 80 cm or less, since the embroidered base fabric can be rolled back. The embroidered base fabric extends over the entire length of the embroidery machine and is supported by the so-called "axis key" in the necessary It $. The diameter of the cloth shaft can be 120 cm, and should be g 1 〇〇 mm, especially $ 9 〇 mm. The cloth shaft (13) (1 50 is coupled by a first and a second chain driver (2) (9) and a coupling means (clutch) (25) [which is disposed between the chain drivers (21) (23)] (25) formed by two serrations having axial projections (3 耦 couplings. 卩 ( (27) (29) (they are designed in the form of a ring) (Fig. 4 to Fig. 6), the first coupling portion (27) A first sprocket (33) of the first chain pivot is firmly connected to be non-rotatable, and the face means (27) and the chain=ring (53) are preferably made into a body. The second portion (29) and the second chain drive (23) - the second sprocket (35 () is firmly connected in a manner that cannot be rotated. The second sprocket (35) and the second merging portion (29) There are two compression elastics (9) between them. They hold the second facing part (29) against the first-synthesis part called the in-coupling position. In this position, the serrations are mutually toothed, and the engaging part is engaged. And the chain, the wheel is rotatably supported on the _ facet shaft (39) (clutch shaft). The turning part (29) and the sprocket (35) can be combined with the _ related design, for example: quadrilateral connection means (39) Transmitting torque. Switching lever (41) [It is fitted with the eccentrically designed head (43) on the second 12 201114970 coupling portion (29)] to make the serration (31) of the coupling portion (29) Disengaged from the first coupling portion (27), so that the chain drivers (21) (23) are decoupled from each other. In the decoupled position, the cloth shafts (13) (15) can independently rotate independently of each other, and for example The embroidered base fabric can be taken up or rolled up. The zigzag shape of the teeth (31) of the above embodiment is used [there are steep side flaps on one side and oblique side flaps on the other side] δ first coupling portion (29 When the first coupling portion is stopped and the first coupling portion is rotated in the direction of the arrow (), the younger part (27) can be moved along the second engaging portion (29) (7) if a coiled embroidery base fabric is required This option is used for clamping.

Here, the stitch plate (10) functions as a counter bearing. As shown in Figure 8, the clamping lever door π ', dry (3) is pivotally supported on a shaft 'drive| § (ordered as a dust end delivery plant ★, Hawthorn wild fine pressure cylinder) It is embedded at one end (88) ^ of the clamping rod (77) and allows the clamping rod (77) to pivot. The fitting rod (5) should not directly embed the embroidered bottom cloth on the stitching plate (75), but use the clamping rib (85). Clamp the rib (10) first onto the pin plate (75) and then with the clamping bar (77) to the pin plate (5). The needle (87) provided on the opposite end of the clamping rib (10) can also be used to lay the edge of the fabric iim (4), and only need to embed the rod with each material, every 3, 4 or 5 embroidery heads can be used. Set a separate clamp bar. In Fig. 9a, the cloth axis (13) (15) and the cloth (4) that is placed between them are shown. Figure number (chuan indicates the needle of the upper unit. To tension the cloth (89), turn the cloth shaft (13) (15) in the opposite direction (arrows 92, 93) until the cloth is tight enough. Figure 9b shows the cloth axis (13) on which is stored a section of the cloth (89) to be punctured (Oat '彡: storage). To embroider the cloth, lay it between the shafts (13) and (15) (Fig. 9〇. When embroidering, the tenter frame moves to the left and right with the cloth axis (13) (15) until The cloth is actually fully embroidered (figure %). Then press the cloth with the clamping ribs (85) onto the stitching plate to prevent the cloth from moving (see Figures 7 and 8). The position is fixed, and the side edge of the cloth can be loosened. 'Where the side edge ribs (not shown) are removed. Then the unconsumed cloth can be taken up, and the cloth shaft (13) (15) is the same. Rotate in the direction of rotation, by the 201114970 frame unreversed / rust direction. (4) The embroidered cloth is taken to the shaft (10). The cloth can be slightly removed from the shaft (13) (Fig. 9e), then, as If necessary, make sure that the tension is not tightened and the clamped ribs are removed. Use the clamp ribs (10) ', ' the needle (91) to change its final position relative to the needle. In the case of post-winding, a sensor can also be used to maintain the final embroidery position of 2. For example, the sensor _1 continues to indicate a point on the base fabric and cooperates with the screaming machine. control The means makes the = point to be in the same position after the rewinding. In practice, the post-winding operation should be synchronized with the moving operation of the tenter frame, so the final position of the spike does not move relative to the needle. The entire width of the embroidery base fabric is evenly tensioned, so that its faces are horizontally tensioned by the "side tensioning ribs" perpendicular to the tensioning direction of the shaft, and at the end, the rear tension is made in the vertical direction. The side of the side portion (17) facing the stab fabric is provided with a guide member, for example in the form of a u-shaped guide channel (97), the towel accommodating a plurality of side clamping portions (99) The side misaligned rib portion (99) is movably disposed in the guide passage (97). When the rear reel is taken, that is, when the embroidered base fabric (89) is wound onto the shaft (13), the side The tensioning rib portion (99) is pushed out from the guiding passage. In order to collect the side tensioning rib portion (99), a storage raft (1〇1 storage) should be attached to the front end of a guiding passage (97). The 匣(1〇1) metric is designed such that the side tensioning rib portions (99) are pushed out from the guiding channel (97) when they are reeled. There is room for storage in the craftsman. If the wind is punctured and then taken up, the storage (101) is attached to the rear end of the guiding passage (97) by a coupling buckle (1〇3) and the side clamping rib portion It is preferred to push it into the guide channel by hand. The embroidery base fabric can then be tensioned by the side, wherein the base fabric is pierced on the needle (1〇5) of the side guiding rib portion (99) of 15 201114970. The side guide rib (9) is preferably a molded piece of 15 to 4 Qem long with a row of needles (1〇5) (Fig. ") on one longitudinal edge (). On its opposite longitudinal edge (_ Guide pins (111), which are fitted into the guide channel (97). The multi-head embroidery machine has a plurality of embroidery heads, and each of the embroidery heads has a plurality of needle positions: two are disposed to be laterally arranged with respect to a stitch position. The way to move is set. The "pin forming member" of each needle position includes at least a state, a plurality of wire guiding devices, and a _ λ , . . pin (located on the -needle push rod, and 7 is movable in the first direction) .
