Definitions
- the present invention relates to a feeding device of a sewing machine, which feeds cloth for sewing placed on a needle plate provided over a sewing machine bed.
- Sewing by a sewing machine is performed by placing cloth for sewing on a needle plate provided over a sewing machine bed, pressing the cloth for sewing with a presser metal which descends to the needle plate, and intermittently feeding it in synchronization with a vertical movement of a needle.
- the presser metal hangs from a sewing machine arm located above the sewing machine bed, and is attached to a tip portion of a presser bar which allows for a rise and fall operation and adjustment of pressure by a user.
- a user of a sewing machine places cloth for sewing on the needle plate in a state where the presser metal is raised, and lowers the presser metal to hold the cloth for sewing.
- Cloth for sewing is generally fed by a movement of feed teeth arranged within a sewing machine bed (for example, refer to Japanese Patent No. 367902 ).
- the feed teeth By transmission from a feeding mechanism provided in the sewing machine bed, the feed teeth perform an elliptic movement in a face perpendicular to the needle plate, and repeats a motion of projecting from the needle plate, performing a feed movement in one direction, retracting below the needle plate and performing a return movement in an opposite direction.
- the cloth for sewing can be fed by an action of the feed teeth performed during the feed movement.
- Document US 3,018,746 describes a feeder for a sewing machine comprising a feed roller that is driven via a transmission gear by the main shaft of the sewing machine the feed roller is further accompanied by feed teeth. Due to the interplay of the forces of the feed wheel and the feed teeth, the cloths for sewing are fed into the sewing machine during the feed movement.
- the present invention has been made with the aim of solving the above problems, and it is an object of the present invention to provide a feeding device of a sewing machine which is capable of reliably and properly feeding cloth for sewing irrespective of a type of cloth for sewing.
- a feeding device of a sewing machine is a feeding device of a sewing machine comprising a sewing machine bed having an upper surface over which a needle plate is provided, and a sewing machine arm which is located above the sewing machine bed and hangs and supports a needle bar and a presser bar towards the needle plate, the feeding device feeding cloth for sewing placed on the needle plate in synchronization with a vertical movement of the needle bar, characterized by comprising: a presser base attached to a lower end of the presser bar; a feed roller supported by the presser base so as to rotate about a shaft extending in parallel with the needle plate; driving means for intermittently driving the feed roller to rotate; and a driven roller supported by a lower part of the needle plate so as to rotate about a shaft extending in parallel with the feed roller; wherein the feed roller sandwiches the cloth for sewing between itself and the driven roller which is exposed to the needle plate by fall of the presser bar, and feeds the cloth for sewing.
- the feed roller which descends with the presser bar rotates in a state where cloth for sewing is sandwiched between the feed roller and the driven roller located on the needle plate, and feeds the cloth for sewing, there is no possibility that a trace caused by feed may remain in the sewn cloth, a proper feed can be reliably performed by adjustment of pressure by the feed roller according to a type of cloth for sewing, and thereby sewing of good quality can be realized simply.
- a feeding device of a sewing machine is characterized in that the driving means has: a feed motor which is fixed and supported outside the sewing machine arm; and a transmitting mechanism which transmits rotation of the feed motor to the feed roller.
- a feed rate of cloth for sewing fed by rotation of the feed roller can be appropriately adjusted by control of the feed motor.
- a feeding device of a sewing machine is characterized by further comprising: an auxiliary presser metal which is mounted on the presser base so as to vertically move, and is located in front of the feed roller; and biasing means for biasing the auxiliary presser metal downward.
- the auxiliary presser metal which is biased downward is arranged in front of the feed roller, the auxiliary presser metal can press cloth for sewing placed on the needle plate, can feed it to a sewing position stably, and can allow for reliable sewing.
- a feeding device of a sewing machine is characterized by further comprising an auxiliary feed tooth which is provided in the sewing machine bed, projects from the needle plate, sandwiches cloth for sewing between itself and the auxiliary presser metal, and feeds the cloth for sewing towards the feed roller.
- the auxiliary feed tooth is provided which projects from the needle plate, sandwiches cloth for sewing between the auxiliary feed tooth and the auxiliary presser metal, and feeds the cloth for sewing, feed to a sewing position can be reliably performed. Moreover, by increasing or decreasing a feed rate fed by the auxiliary feed tooth, an extension degree of cloth for sewing between the auxiliary feed tooth and the feed roller can be changed, and thereby cloth with high stretchability can be sewn satisfactorily.

- the needles 12 which descend with the needle bar 1 pass through a needle hole (not shown) provided in the needle plate 3 corresponding to the needle hole 28, and can enter the sewing machine bed provided on a lower part of the needle plate 3. Note that the needle bar 1 and the needles 12 shown in FIGS. 1 and 2 are in a rise position.
- a driven roller 30 is attached to the back part of the needle plate 3 corresponding to a fall position of the feed roller 5.
- the driven roller 30 is rotatably supported by a supporting shaft 32 laterally extending in parallel with the needle plate 3 through a bracket 31 projecting from a lower face of the needle plate 3.
- Apart of the driven roller 30 is exposed on an upper side of the needle plate 3, and contacts and rolls the feed roller 5 which descends as mentioned above.
- the cloth for sewing is sandwiched also between the feed roller 5 and the driven roller 30.
- the feed roller 5 rotates by transmission from the feed drive shaft 40 provided in the sewing machine arm.
- the feed drive shaft 40 is juxtaposed to the arm shaft 4, and is supported in the sewing machine arm.
- a swinging lever 41 is fixed in the middle of the feed drive shaft 40, and is connected to an eccentric ring 42 fitted onto the middle of the arm shaft 4.
- the arm shaft 4 is a rotary shaft which rotates in one direction by transmission from a sewing machine main shaft.
- the eccentric ring 42 reciprocates based on eccentricity according to rotation of the arm shaft 4, and the reciprocation is transmitted to the feed drive shaft 40 via the swinging lever 41.
- the feed drive shaft 40 repeatedly rotates about a center axis in an angular range corresponding to the eccentricity of the eccentric ring 42.
- a one end part of the feed drive shaft 40 extends even close to back positions of the needle bar 1 and the presser bar 2, and a swinging arm 43 is fixed to the one end part of the feed drive shaft 40.
- a feed transmission shaft 44 is provided at the back position of the presser bar 2.
- the feed transmission shaft 44 is a short sliding shaft which is supported by a support bush 45 so as to slide upward and downward, and an upper end part of the feed transmission shaft 44 extending into the sewing machine arm is connected to the swinging arm 43 fixed to the one end part of the feed drive shaft 40 via an upper link 46.
- feed transmission shaft 44 reciprocates upward and downward according to repeated rotation of the feed drive shaft 40.
- a lower end part of the feed transmission shaft 44 extending outside the sewing machine arm is connected to a transmission bracket 48 via a lower link 47.
- the transmission bracket 48 is a flat U-shaped member which is open on one side, is fitted onto the support arms 23, 23 of the presser base 21 in a state where the open side faces the front, and is connected to end parts of the supporting shaft 50 of the feed roller 5 which project on the respective sides.
- one-way clutches 6 are incorporated into the projecting end parts of the supporting shaft 50 respectively, and the transmission bracket 48 is connected via the one-way clutches 6 provided on the respective sides.
- the transmission bracket 48 swings about the supporting shaft 50 of the feed roller 5 provided as a center according to the reciprocation of the feed transmission shaft 44 transmitted via the lower link 47. This swing is transmitted to the supporting shaft 50 of the feed roller 5 via the one-way clutches 6. Thereby, the feed roller 5 rotates only during the swing in one direction of the transmission bracket 48 by the upward movement or the downward movement of the feed transmission shaft 44, and can intermittently feed cloth for sewing sandwiched between the feed roller 5 and the driven roller 30.
- feed roller 5 rotates by transmission from the arm shaft 4 provided in the sewing machine arm, and the needle bar 1 and the needles 12 also vertically move by transmission from the arm shaft 4, feed of cloth for sewing by rotation of the feed roller 5 is performed in synchronization with the vertical movement of the needles 12, and the cloth for sewing can be sewn by the vertical movement of the needles 12 and a movement of a looper (not shown) provided below the needle plate 3.
- Cloth for sewing can be reliably fed by increase of pressure for sandwiching between the feed roller 5 and the driven roller 30, and for example, even at the time of sewing slippery cloth, deterioration of a finish quality of a sewn product resulting from poor feed can be prevented.
- the pressure for sandwiching cloth for sewing can be adjusted by increasing or decreasing a spring force of a compression spring (not shown) for pressing and biasing the presser bar 2 downward, and by changing pressure of the feed roller 5.
- the adjustment is the same as adjustment of pressure to be performed for a presser metal provided in the conventional sewing machine. Note that much more reliable feed can be realized by coating surfaces of the feed roller 5 and the driven roller 30 using a material with a high friction coefficient.
- a plurality of feed holes 33 long forward and backward are provided in the front part of the needle plate 3 which the auxiliary presser metal 25 contacts, and a plurality of auxiliary feed teeth 34 are provided in lower parts of the feed holes 33 so as to project or retract, respectively.
- the auxiliary feed teeth 34 repeat a known motion of projecting from the needle plate 3 through the feed holes 33, performing a feed movement backward, retracting below the needle plate 3 and performing a return movement forward.
- the auxiliary feed teeth 34 sandwich cloth for sewing between themselves and the auxiliary presser metal 25, and intermittently feed the cloth for sewing while projecting from the needle plate 3 and performing the feed movement.
- the auxiliary feed teeth 34 have non-slip teeth on upper surfaces thereof which act on cloth for sewing, since the auxiliary presser metal 25 which sandwiches cloth for sewing between itself and the auxiliary feed teeth 34 moves upward against the spring forces of the compression springs 26 for biasing downward and alleviates pressure of the auxiliary feed teeth 34, there is no possibility that shapes of the auxiliary feed teeth 34 may remain in the sewn cloth.
- Feed by the auxiliary feed teeth 34 is performed to assist feed of cloth for sewing to fall positions of the needles 12 for sewing.
- a feed rate thereof can be adjusted by an operation of the feeding mechanism separately from a feed rate added by the feed roller 5. The adjustment is performed in order to prevent extension of cloth for sewing by feed and improve a quality of a sewn product, for example at the time of sewing cloth for sewing with high stretchability.
- FIG. 3 is a perspective view showing a feeding device of a sewing machine according to Embodiment 2.
- FIG. 3 is illustrated as a perspective view from the back of the sewing machine contrary to FIG. 1
- Embodiment 2 is the same as Embodiment 1 shown in FIGS. 1 and 2 except driving means of the feed roller 5, and reference numerals common to FIGS. 1 and 2 are given to corresponding component members, and descriptions and movements thereof are omitted.
- the feed roller 5 is driven to rotate by a dedicated feed motor 8.
- the feed motor 8 is fixed to a rear surface of a tip part of a sewing machine arm 7 via a supporting bracket 80.
- the supporting bracket 80 has a support plate which vertically rises from the rear surface of the sewing machine arm 7, and the feed motor 8 is mounted on the support plate.
- the feed motor 8 projects towards the tip part of the sewing machine arm 7, and has an output shaft extending in parallel with the supporting shaft 50 of the feed roller 5 and a drive pulley 81 is fitted and fixed to the output shaft.
- the supporting shaft 50 of the feed roller 5 projects from the support arm 23 provided on one side of the presser base 21, a driven pulley 51 is fitted and fixed to the projecting end part, and the driven pulley 51 and the drive pulley 81 are connected to each other via a transmission belt 82 suspended therebetween.
- the feed motor 8 is a stepping motor which is intermittently driven for a predetermined period, and rotation of the feed motor 8 is transmitted to the feed roller 5 via the drive pulley 81, the transmission belt 82 and the driven pulley 51, and thereby the feed roller 5 rotates. Therefore, the feed movement similar to that in Embodiment 1 can be performed by drive of the feed motor 8 in synchronization with a vertical movement of the needle bar 1 and the needles 12.
- the drive pulley 81 and the driven pulley 51 are synchronous pulleys comprising teeth in outer circumferences thereof and the transmission belt 82 is a synchronous belt comprising teeth in an inner surface thereof, rotation of the feed motor 8 is transmitted to the feed roller 5, without slip, and thereby the more reliable feed movement can be performed.
- An air cylinder 83 is fixed to the supporting bracket 80.
- the air cylinder 83 is located above a front side of the feed motor 8 and has an output rod extending below, and a supporting member 84 is mounted on a lower end of the output rod.
- the supporting member 84 is a U-shaped member which is open on the downside thereof, and a tensioning pulley 85 located inside transmission belt 82 is attached close to open end parts extending so as to sandwich both sides of the transmission belt 82.
- the air cylinder 83 is usually in a shown projection position. At this time, the tensioning pulley 85 does not contact the transmission belt 82, and the transmission belt 82 is in a state where it is suspended between the drive pulley 81 and the driven pulley 51. Tension of the transmission belt 82 is lost when the feed roller 5 moves upward by rise of the presser bar 2.
- the air cylinder 83 raises the tensioning pulley 85 via the supporting member 84, according to the upward movement of the feed roller 5.
- the tensioning pulley 85 contacts a corresponding portion of the transmission belt 82, pulls up it, maintains tension of the transmission belt 82, and prevents the transmission belt 82 from separating from the drive pulley 81 or the driven pulley 51.
- a transmitting mechanism which transmits rotation of the feed motor 8 to the feed roller 5 is not limited to the belt transmission mechanism comprising the drive pulley 81, the driven pulley 51 and the transmission belt 82, and other transmitting mechanisms, such as a gear transmission mechanism, may be used.
