This device for compensating the allowance between two components, that are the cutting knife 3 and the cutting block 2 provided in a sewing machine so as to cut a buttonhole, is provided. One of the components 2 and 3 is fixed and the other component can be settled on the fixed component by acting devices 4, 5 and 6 movable from an upper end part position to a lower end part position. At least one of the components 2 and 3 is spring elastically supported.

Description

Device for the cutting device compensate
The present invention relates to a kind ofly to be used to compensate between two parts, i.e. the device of a cutting knife and a cutter interblock deviation, these two parts are positioned on the Sewing machines and are used for the cutting buttonhole, wherein, one in two parts is fixed-site, and another can drop to by the effect of a manipulation device on these parts of fixed-site, and this manipulation device can be moved to a lower terminal position by a upper terminal position.
This compensation arrangement can be used on the eye-shaped buttonhole Sewing machines, for example, and as what sold with D ü rkopp Adler Kl.558 title by the applicant.
A kind of Buttonhole sewing machine is cutting pattern or moved under the cutting pattern of back formerly.Formerly under the cutting pattern, first cutting buttonhole stitches buttonhole caterpillar shape drawing lines then, and under the cutting pattern of back, the buttonhole drawing lines has been stitched out, cuts out otch then between drawing lines.Because cutting knife switches on the cutter piece in running, therefore, cutting knife and cutter piece belong to an integral body of cutting device.When the parts of mutual coupling are employed, just may cut out neat beautiful otch.If cutting knife is because wearing and tearing must be replaced, the cutter piece also must be replaced.
The driving that can drop to the cutter piece on the cutting knife is selected like this, and promptly the cutter piece lies against on the cutting knife at its lower end position, but moving downward of continuing is excluded, this continuation move downward the wearing and tearing or the breakage that can cause parts.Therefore in vertical direction coverage (Uberdeckungsbereich) just in time is big like this between cutter piece and the cutting knife, promptly guarantees a neat otch." coverage " understood like this, although promptly cutter is cut and touched cutting knife, the lever of manipulation device also carries out moving downward of a continuation.For this reason, when the cutter piece had too strong cutting knife impression, this cutter piece can not or only be trimmed by grinding in very little scope, because, otherwise its height dimension becomes too little, and this cutter piece no longer can touch cutting knife.Owing to this reason, this cutter piece must be replaced basically.Another kind of possibility is to adjust the driving of cutter piece like this after finishing, even lower terminal position changes corresponding to the finishing of being carried out.Yet this can cause all other cutter pieces that can be used to this machine must be finished to identical height dimension equally.
In order to address this problem, should create a kind of device that is used for Buttonhole sewing machine, can compensate deviation between cutting knife and the cutter piece by means of it.
This problem is solved thus, and promptly at least one of these parts flexibly supported and settle.
Can between cutting knife and cutter piece, adjust a bigger vertical coverage by this structure.Promptly, when these parts on dropping to another parts and it are in a horizontal plane, for this parts manipulation device that will descend does not also need to have arrived its lower terminal position,, flexibly supported these parts of settling can be offset because in the decline that continues.Thus, avoided effectively damaging or excessive wearing and tearing.
The advantage of this arrangement is that the cutter piece can individually be trimmed or individually be replaced, and does not therefore relate to the cutter piece that other alternately uses on this machine.Also needn't change the terminal location of manipulation device.
Especially, elastic bearing realizes like this, is about to these parts that can descend and is contained in the anchor clamps that link with manipulation device, and these anchor clamps can overcome the power of at least one spring in vertical direction with respect to the manipulation device relative motion at lower terminal position.
Especially holding an end of axle journal in anchor clamps inside, this axle journal is imported in the bearing of a fixed-site, is acting on manipulation device on the other end of axle journal.In addition, settled a spring at least between axle journal and anchor clamps, wherein, this relative motion occurs between axle journal and anchor clamps, and this bearing is arranged between anchor clamps and the manipulation device.
When axle journal is loaded by a compression spring that is bearing on the bearing, the simple fixation of anchor clamps and prevent that the protection that drops out is implemented.In addition particularly, at least one spring is made of groups of springs (Federpaket) in anchor clamps.
If below the bottom of parts settle a block rubber, flexibly mounted another program then is provided.
If the parts of this below have anchor clamps and a plate, block rubber can be positioned between these anchor clamps and the plate, and these anchor clamps and block rubber and plate are configured the all-in-one-piece parts.This can be by the sulfuration or bonding realization of parts.Only changing into by one, parts make the fixing simplification of supporting.In addition,, therefore make manufacturing cost little owing to there is not movable part, and the elastic device reliable operation.
Especially advantageously, if but the part detachable ground of descending motion be connected with its anchor clamps.Thus can be rapidly and change parts simply.If but the parts of this descending motion are the cutter pieces, a plurality of cutter pieces can be installed, they be installed in one removably with carriage that anchor clamps are connected on.Further simplified the replacing of cutter piece thus.By with carriage by unloading on the anchor clamps, and rotate thus, make to forward action direction to for the other set cutter piece of pattern, can be transformed into cutting pattern afterwards by first cutting pattern very simply, perhaps be the otch replacing equipment more of cutting all lengths.To this, each cutter piece has different length.

As shown in Figure 1, Buttonhole sewing machine is equipped with the device 1 that is used to cut buttonhole.This device 1 mainly is made of cutter piece 2 and cutting knife 3.Cutter piece 2 can be landed towards cutting knife 3 to its lower terminal position by the upper terminal position shown in the figure by a manipulation device of forming by a lever 4,5 and a continuous cylinder thereof basically.At this, making of keeping flat on plane 7 cuts out buttonhole on the thing.The stitch plate of not describing in detail for example also is positioned on the plane 7 herein.The location of the arrangement of lever 4,5 and cutting device 1 is settled and is selected like this, promptly makes cutter piece 23 move along straight line towards cutting knife in vertical direction.
For the various buttonhole length of energy cutting, on this Sewing machines, be provided with 3 cutter piece 2a, 2b, 2c, they respectively have different length l 1, l 2, l 3(directions X).Selected the cutter piece 2a of respective length by use, 2b, 2c form otch only making on the thing on cutter piece 2 bumps against the position of cutting knife 3.Can not be cut open making the position that exceeds cutter piece 2 that thing lies on the cutting knife 3.
Three cutter piece 2a, 2b, 2c indicate with position symbol 2 generally, and they are positioned in a cross section is on the hexagonal carriage 21 (Fig. 6).Wherein, the hexagonal face between per two cutter pieces 2 is idle.As shown in Figure 6, each cutter piece 3 all is fixed on the carriage 21 by at least one bolt 25.Carriage 21 is connected with anchor clamps 22 through a quick retaining mechanism, and the feasible tool using that do not need promptly can be with carriage by manually unloading on the anchor clamps 22.Can make this machine adjust to other buttonhole length or cutting pattern simply by this structure, promptly carriage 21 be unclamped by anchor clamps 22, it is rotated, the cutter piece 2 of desired length be turned to cutting knife 3, and then carriage 21 is connected on the anchor clamps 22 by the operator.
As shown in figure 13, can carry out this connection by a pin 23, it can be inserted in the hole 24 of relative configurations on the carriage 21.For carriage 21 is fixed on the anchor clamps 22, be provided with supporting plate 17,18 in latter both sides, yet they are screwed in and can limitedly move with anchor clamps 22 through screw 19.A supporting plate 18 is provided with a through hole in its underpart, another supporting plate 17 is being provided with a hole 37 (Fig. 8) of having opened groove with above-mentioned through hole coaxial line place.This pin 23 has a pin perpendicular to its longitudinal axis arrangement.By inserting in the hole 37 of slotting pin 23 and half-twist, this pin is screwed into the back of supporting plate 17, and cooperates with supporting plate 17, has prevented that pin 23 from dropping out.
This quick connection also can be carried out like this, that is: carriage 21 is connected with anchor clamps 22 magnetic, for example in anchor clamps 22-be not shown specifically-settle an electromagnet here, it holds the carriage of being made by ferromagnetic material 21.By corresponding auxiliary guiding and auxiliary centering, must guarantee reliably that carriage 21 always is in a definite position with respect to anchor clamps 22, thereby guarantee to use each cutter piece 2 to cut out buttonhole reliably.
By in anchor clamps 22, inserting a permanent magnet 50, also can be provided with and realize that a simple magnetic clamps, and in addition, side at permanent magnet 50 is provided with pin 51, they protrude in downwards outside the anchor clamps 22, by the hole 52 on carriage 21 corresponding to pin 51 make carriage with respect to machine or anchor clamps 22 centerings, prevent to rotate and by permanent magnet 50 fixing (seeing Figure 15).
In the stitch plate that is not shown specifically (plane 7) below, in cutter holder 30, fixing cutting knife 3, this cutter holder 30 is again through a plate 32 and tool rest 31 screw-drivings.For can be with straightforward procedure and mode compensate, this deviation may be passed through single cutter piece 2a when the cutting buttonhole, 2b, and the differing heights size H of 2c produces, and this cutting knife 3 can be bearing on the block rubber 33 with suitable Shore hardness.To this, as shown in figure 10, this block rubber 33 is positioned between the cutter holder 30 and plate 32 of clamping cutting knife 3, and wherein, cutter holder 30, block rubber 33 and plate 32 are made into parts in a sulfidation.In addition, the connection between this parts also can be by gluing realization.This cutting knife 3 is fixed on the cutter holder 30 by two screws 35 of at least one clamping plate 34 usefulness.
The advantage that is used to compensate the device of deviation between cutter piece 2 and the cutting knife 3 is, as cutter piece 2a, 2b, one of 2c be because wearing and tearing and must finishing or when changing, and each cutter piece 2a, 2b, 2c self can be trimmed or change and will cutter piece 2 monolithic finish or replacing.The effect of offset compensation device is, effect by manipulation device and axle journal 10 makes cutter piece 2 move to lower terminal position, be in the terminal location that it is determined at this terminal location upper lever transmission device, and on the lower terminal position of cutter piece 2, or cutting knife 3 can be downwards or cutter piece 2 can be to top offset,-as following also will further describe-, for fear of mechanical overload or even the damage of parts.Thisly be limited in practice below the 1mm, always at a few tenths of a mm at the possible displacement movement of vertical direction.
In order to allow cutter piece 2 relative motion in vertical direction, anchor clamps 22 are settled versatilely with respect to axle journal 10, and downward motion is imported through axle journal 10 through lever 4,5 by manipulation device.Axle journal 10 has one with its shaft shoulder that broadens 11, is installed in the pin-and-hole 28, and the diameter of this shaft shoulder approximates the diameter in hole 28 greatly.Settled the groups of springs 27 of a precompressed in hole 28, it is bearing in the bottom in hole 28 on the one hand, is bearing on the other hand on the shaft shoulder 11.The lower end 10 ' of axle journal 10 protrude in concentric hole 29, hole 28 in, yet before the end of anchor clamps 22, stop.So as shown in figure 13, leave a cavity 26 between the lower end 10 ' of axle journal 10 and carriage 21, wherein, the space height of this cavity has been determined the relative motion of the maximum possible of cutter piece 2.The location of axle journal 10 in anchor clamps 22 realizes that by a safety collar 13 it is placed in the opposing on the side of groups of springs 27 of the shaft shoulder 11.The upper end 10 of axle journal 10 " be imported in the sliding bearing sleeve 9 in a bearing 8 that links to each other with Sewing machines wall 15.By the spring 14 of a precompressed, this spring-loaded links to each other with axle journal 10 in bearing sleeve 9 is taken out in slip and through a safety collar 16, makes the parts terminal location fixed thereon that is made of cutter piece 2, cutter piece carriage 21 and anchor clamps 22.Compression spring 14 is simultaneously as back-moving spring.
If the piston rod of cylinder 6 outwards moves, lever 4 moves downward, and the power that thus axle journal 10 is overcome compression spring 14 is to pressing down and make cutter piece 2 to cutting knife 3 motions.The mobility of supporting plate 17,18 makes on diameter and cutter piece 2a, 2b, and opposite opposed of 2c contacts with anchor clamps 22 on its whole length, and therefore realizes the power transmission of an optimization.If before lever 4 arrived its lower terminal position, cutter piece 2 was run into cutting knife 3, the power that anchor clamps 22 overcome spring 27 is defeated in reaction, thereby makes it with respect to axle journal 10 motions, reaches its lower terminal position until lever 4.
In order to ensure for each course of work, use the carriage 21 that has correct selection cutter piece 2 (to cooperate correct length l 1, l 2, l 3), shown in Figure 14 to 16, carriage 21 is equipped with coding 40.This coding 40 is made of single light reflector 41, and they are placed on the extension 42 on the carriage 21 with certain length.Machine is provided with a light reflector fixture 42 regularly, settles single photoconduction line 43 (for example optical fiber (Glasfaserkabel)) thereon.By this optical scanning to employed carriage 21, can detect by corresponding treatment circuit in controller 44, employed carriage 21 is complementary with just selected sewing process.
Coding 40 shown in Figure 15 and 16 is equipped with 4 light reflectors 41, produces 2 thus 4=16 codifiabilities.Therefore, it for example can identify 15 kinds of cutter piece 2a that settle on various carriage 21,2b, and 2c sends corresponding signal and give controller 44, and (Fehlen) sends an other signal to controller 44 when set carriage 21 lacks.
