- the US 2005/0178307 A1 describes a quilting machine.
- the EP 2 206 820 A1 describes a thread cutting device for a sewing machine.
- an upper thread detection section of an upper thread knife can be used simultaneously for clamping a seam starting upper thread and also for shearing off the seam starting upper thread in order to produce a defined short seam starting upper thread.
- a compact assembly which on the one hand ensures a clamping and on the other hand a cutting of the upper thread, is thus made possible.
- the counter knife can also represent the upper thread clamp. Alternatively, it is possible to design the upper thread clamp as a separate component from the counter knife.
- the counter knife can be arranged fixed to the frame. Alternatively, it is possible that the counter knife moves relative to a frame of the sewing machine during cutting.
- the upper thread gripping position, the upper thread clamping position and the upper thread cutting position are mutually different positions of the upper thread gripping section.
- the upper thread clamping position can be a position of the upper thread gripping section which lies between the upper thread gripping position on the one hand and the upper thread cutting position on the other hand.
- a displacement drive according to claim 2 is inexpensive.
- a displacement drive according to claim 3 is precise.
- the displacement drive can be designed as a lifting cylinder and in particular as a pneumatic lifting cylinder.
- the displacement drive can be designed as a stepper motor.
- This stepping motor can be controlled with a corresponding control in such a way that the three positions of the upper thread detection section correspond to corresponding stepping positions of the stepping motor. With such a stepper motor design, stops for presetting the position can be dispensed with.
- An adjustable clamping position stop according to claim 4 simplifies the manufacture of the assembly.
- a clamping position stop according to claim 5 is inexpensive to manufacture. Self-locking can be achieved by screwing the threaded pin into a plastic body fixed to the frame.
- An adjustable cutting position stop according to claim 6 simplifies the manufacture of the assembly.
- a stop body according to claim 7 enables precise adjustment of the cutting position stop, a force that is absorbed by the cutting position stop not acting in the direction of displacement of the stop body, which could lead to undesired slippage of the stop.
- a suction device avoids undefined deposition of sections of the upper thread. This prevents undesirably cut thread remnants from collecting in the area of the sewing machine.
- a sewing machine 1 designed in particular as a lockstitch sewing machine has a base plate 2 with a stand 3 extending upward therefrom and an angled arm 4. The latter ends in a head 5.
- an arm shaft 6 is rotatably mounted.
- the crank drive 7 is drivingly connected to a needle bar 9 which is mounted axially displaceably in the head 5.
- the needle 10 can be moved up and down on a vertical axis 11 by the crank mechanism 7.
- a Cartesian xyz coordinate system is used below.
- the vertical axis 11 runs along the z direction of this coordinate system.
- the x-direction runs perpendicular to the plane of the drawing Fig. 1 into this and runs parallel to a sewing direction of the sewing machine 1.
- the y-direction runs in the Fig. 1 to the left.
- the needle 10 guides in an eye a needle thread 13, which is also referred to as the upper thread, which is fed from a bobbin 12 via a thread tensioning device and the thread lever 8.
- the needle thread 13 has a free upper thread starting section 13a.
- the base plate 2 carries a support plate 14 which is fastened with screws and on which a workpiece 15 rests.
- the support plate 14 has a recess designed for the passage of a lower material slide 17.
- the latter has a needle hole 18 for the needle 10 to pass through.
- a gripper 19 which has a gripper body 20 with a gripper tip 21.
- a cup-shaped bobbin housing 22 for receiving a supply of hook thread in the form of a bobbin 22a is mounted in the hook body 20.
- Upper edge contours on the one hand of the coil housing 22 and on the other hand of the coil 22a are shown in the schematic illustration according to FIG Fig. 2 indicated by dashed lines.
- the looper thread is also known as the bobbin thread.
- the gripper 19 can be rotated about a vertical gripper axis 23 running in the z direction.
- a sewing operation direction of rotation 24 of the hook body 20 runs in FIG Fig. 3 clockwise around the gripper axis 23.
- the gripper body 20 is firmly connected to a shaft 25 which runs coaxially to the gripper axis 23.
- the shaft 25 is rotatably supported in a bearing block 26 screwed to the base plate 2.
- a drive shaft 27 is mounted, which is connected to a gear mechanism arranged in the interior of the bearing block 26.
- the gear transmission has a transmission ratio of 1: 2, so that with one revolution of the drive shaft 27, the gripper body 20 located on the shaft 25 rotates twice.
- the drive shaft 27 is drivingly connected to the arm shaft 6 via a belt drive 28.
- a thread-pulling knife 29 (cf. Fig. 3 ), for example from the EP 1 847 641 B1 is known.
- the sewing machine 1 To hold and transport the workpiece 15, the sewing machine 1 also has a presser foot 30 and an upper conveyor 31, which interacts with the lower material slide 17 for transporting the workpiece.
- the schematic Figure 2 also shows a course of the upper thread 13 from the bobbin 12 to the upper thread starting section 13a.
- the upper thread 13 is guided to the needle 10 via a thread tensioning device 32 and the thread lever 8 and an upper thread guide clamp 33.
- the upper thread guide clamp 33 has a tension washer 34 which is attached to a guide rod 35.
- the tensioning disk 34 is pulled via a compression spring 36 against an abutment 37, which is fixed to the housing, of the upper thread guide clamp 33 in order to clamp the upper thread 13.
- abutment 37 is a in the Fig. 2 attached schematically shown electromagnet 38, which is controlled via a central control device 39 of the sewing machine 1 in a manner not shown.
- the assembly 40 is arranged on a side of this xz plane opposite the gripper 19 (cf. Fig. 1 and 3 ).
- the assembly 40 has an upper thread catcher 41 for grasping a seam starting upper thread at the beginning of a seam to be sewn with the needle thread 13.
- the upper thread catcher 41 has an upper thread knife 42 (see. Eg Fig. 5 ) with an upper thread gripping section 43 designed as a passage opening.
- the upper thread catcher 41 also has a counter knife 44 which cooperates with the upper thread knife 42 to cut the needle thread 13.
- the counter knife 44 is fixedly arranged in relation to a frame of the sewing machine 1.
- the upper thread catcher 41 has an upper thread clamp 45.
- the latter is designed as a U-shaped clamping spring.
- a contact pressure of the clamping spring 45 against the needle thread knife 42 can be set via a clamping spring adjusting screw 46.
- a knife pressure, that is to say a contact pressure of the counter knife 44 against the upper thread knife 42, can be set by means of a knife adjusting screw 47.
- the upper thread detection position is in the Figures 4 to 6 shown.
- the upper thread clamping position is in the Figures 7-11 shown.
- the upper thread cutting position is in the Figures 12 to 15 shown.
- the upper thread gripping position, the upper thread clamping position and the upper thread cutting position are mutually different positions of the upper thread gripping section 43. These three positions can be specified with the displacement drive 48, that is to say with exactly one drive.
- a linear guide guides a displacement movement of the upper thread detection section 43 between the three aforementioned positions.
- the linear guide comprises a guide pin 49 which runs approximately in the z-direction and is attached to a connecting piston 50 which is connected to a piston rod 51 of the lifting cylinder 48 in a tensile manner.
- the guide pin 49 interacts with an elongated hole 52 in a mounting plate 53 of the assembly 40 to guide the displacement movement of the upper thread gripping section 43 (cf., for example, FIG Figures 4 and 5 ).
- the upper thread knife 42 is attached to the guide pin 49.
- the upper thread knife 42 In the upper thread detection position, the upper thread knife 42 is extended in the negative y-direction relative to the counter knife 44 so that the upper thread detection section 43 projects completely over the upper thread knife 42 and the upper thread clamp 45 and is freely accessible for the needle 10 to pass through.
- An adjustable clamping position stop is used to preset a relative position of the upper thread knife 42 to the upper thread clamp 45 in the upper thread clamping position.
- the clamping position stop contains a threaded pin 54 which is screwed into a plastic body 55. This results in a self-locking design of the threaded pin 54.
- In the stop position of the clamping position stop i.e. in the upper thread clamping position after the Figures 7-11 , strikes a free end of the threaded pin 54 on the guide pin 49 and thus limits a movement of the upper thread knife 42, starting from the upper thread detection position in the positive y-direction, for example in the Fig. 7 to the left.
- the threaded pin 54 is correspondingly rotated relative to the plastic body 55.
- the threaded pin 54 is via a passage opening 56 (cf. Fig. 8 ) in a drive support plate 57 accessible from the outside.
- the clamping position stop is between a particular in the Fig. 7 shown stop position and an ineffective neutral position displaceable. This neutral position is for example in the Figure 12 shown.
- a clamping stop drive 58 which is also designed as a pneumatic lifting cylinder, is used for this displacement of the threaded pin 54 of the clamping position stop.
- the plastic body 55 is connected to the clamping stop drive 58 via its piston rod 59.
- the plastic body 55 is supported on the drive support plate 57 against the pretensioning force that the guide pin 49 exerts on the threaded pin 54 (cf. Fig. 7 ).
- the clamping stop drive 58 is also mounted on the drive support plate 57.
- the drive support plate 57 is bent into an L-shape, the upper thread gripping section displacement drive 48 being mounted on a first leg and the clamping stop drive 58 being mounted on a second leg of this L-shape.
- a displacement movement by the clamping stop drive 58 takes place approximately perpendicular to the displacement movement by the displacement drive 48.
- the upper thread In the upper thread clamping position, the upper thread is clamped between the upper thread clamp 45 and the upper thread knife 42. This clamping position is such that a cutting edge of the upper thread knife 42 does not yet interact with the counter knife for cutting the upper thread 13.
- the assembly 40 also has an adjustable cutting position stop for specifying a relative position of the upper thread knife 42 to the counter knife 44 in the upper thread cutting position.
- the cutting position stop has a stop body 60, which is supported by a stop plate (see Figures 12 and 13 ) is formed. The latter in turn interacts with the guide pin 49 of the assembly 40 in the cutting stop position of the cutting position stop.
- a contact between the guide pin 49 and the stop plate 60 takes place in the area of an inclined wall section 61 of the stop plate 60, that is to say in the area of a Edge section, which in the plan after Fig. 13 assumes an angle to the x-axis or to the sewing direction.
- a relative position of the stop plate 60 to the mounting plate 53 can be specified via a mounting connection which has an adjusting screw 62 which runs through an elongated hole 63 in the stop plate 60 running along the x-direction (cf. Fig. 13 ).
- the stop plate 60 is displaced along the x direction so that a contact area between the guide pin 49 and the inclined wall section 61 in the cutting stop position moves accordingly along the y direction.
- the stop body 60 can be displaced transversely to a cutting movement direction of the upper thread knife 42, that is to say transversely to the y direction.
- the stop plate 60 In the stop position of the cutting position stop (cf. Fig. 13 ) the stop plate 60 is supported against the pretensioning force by the guide pin 49 on the drive carrier plate 57.
- the cutting position stop acts when the clamping position stop has moved into the neutral position.
- the assembly 40 also has a suction device 64 for suctioning off a section of the upper thread 13 that has been cut off with the upper thread knife 42 Upper thread knife 42 and the counter knife 44 opens out (cf. Fig. 12 ).
- An opposite end 66 of the suction pipe 65 is connected to a vacuum source (not shown) of the suction device 64.
- a section of the needle thread 13 is first transported from the upper side of the sewing material to a lower side of the sewing material 15 in the upper thread grasping position of the upper thread grasping section 43, the needle 10 passes through the opening of the upper thread engaging portion 43. Then the upper thread starting section 13a is pulled out with the looper 19 until the entire upper thread starting section 13a lies under the underside of the sewing material 15. After a first short stitch, when the thread lever 8 is in the region of the top dead center, the upper thread gripping section 43 is brought out of the upper thread gripping position into the drawn in upper thread clamping position by actuating the displacement drive 48.
- the seam is then sewn with the normal stitch length.
- a stitch length is preset with the aid of the control device 39.
- the further seam with the participation of the upper thread 13 and the lower thread can be designed as a lockstitch seam.
- a thread cutting operation of the upper thread 13 and the lower thread with the thread-pulling knife 29 then takes place.
- FIG. 10 shows a seam 67 produced with the sewing assembly 40 in a seam starting section.
- the sewing direction runs along the x-direction in the Fig. 6 to the left. Because of the upper thread section between the upper thread knife 42 and the counter knife 44, the upper thread starting section 13a at the beginning of the seam 67 is so short that a maximum seam protrusion A of 10 mm results.
- the displacement drive 48 can also be designed as a stepping motor, the different positions of the upper thread detection section 43 then corresponding to different stepping positions of the stepping motor. These different step positions can be specified via the control device 39.
