本発明は記憶した縫製情報にしたがって自動縫製する自
動縫いミシンにおいて、縫製中の布を押える布押え装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a cloth presser device for pressing cloth during sewing in an automatic sewing machine that automatically sews according to stored sewing information.
記憶素子に記憶させた縫製情報にしたがい仮縫製物を布
保持板で挾持させながら任意の方向に移動させて自動縫
製する自動縫いミシンが周知であり、工業用ミシンを始
めとして家庭用ミシンとしても広く実用化されている。Automatic sewing machines that automatically sew by moving temporarily sewn items in any direction while holding them between cloth holding plates according to sewing information stored in a memory element are well-known, and can be used not only as industrial sewing machines but also as household sewing machines. It has been widely put into practical use.
この種自動綿いミシンには縫製中の布を押える布押え装
置が設けられており、自動縫製時には布送り作用を円滑
にするため通常この布押え装置の布押えを布送りに支障
がない程度の高さに設定して縫製が行なわれる。すなわ
ち、被縫製物が複数枚の布を重ね縫いするいわゆる平縫
いの場合には、縫製枚数に対応した布押えの高さが設定
される。This type of automatic cotton sewing machine is equipped with a presser foot device that presses the cloth during sewing, and in order to ensure smooth cloth feeding during automatic sewing, the presser foot of this presser foot device is usually held at a level that does not interfere with cloth feeding. Sewing is performed by setting the height to . That is, when the object to be sewn is so-called plain stitching in which a plurality of cloths are sewn one on top of the other, the height of the presser foot is set in accordance with the number of cloths to be sewn.

ばたつき、目飛びや先締り不良等が発生して円滑、適正
な自動縫製がなされないことがあシ、従来からその改良
が要語されていた。However, this is fine if the material to be sewn is plain stitched from the beginning to the end of sewing, but it is not possible to combine so-called step stitching and flat stitching in which the number of sewn pieces or the thickness of the fabric changes during sewing in one sewing pattern. If the height of the presser foot is set for flat stitching, the presser foot will hit the step when it comes to the step sewing area, making it impossible to sew. If the height of the presser foot was set for 1st stitch, there was a drawback that the appropriate presser foot action could not be obtained in the plain seam section.
Therefore, conventionally, in order to make it possible to sew a workpiece that has flat stitches and step stitches in one sewing turn, the height of the presser foot can be moved up and down to change between, for example, 2 mm and 5R+. However, in conventional automatic sewing machines equipped with this type of presser foot that can move up and down, the presser foot cannot be used during plain stitching. When the needle passes through the fabric, the fabric flaps, causing skipped stitches and poor stitching, which prevents smooth and proper automatic sewing. It was summarized.

布押え１２の上下運動量が零になる。The bell crank 24 has one free end pivotally connected to a link 39, which will be described later, and the other free end, which is supported by a stepped shaft 47 and a protruding shaft 48, which will be described later. In normal times, the movement of the fulcrum position is restricted by the L fitting 23, but by rotating the adjusting screw 21 and expanding and contracting the compression coil spring 26 on the spring shaft 22, the spring shaft 22 can be moved up and down. Bell crank 24 with metal fittings 23
The fulcrum position is configured to move. That is, on the main shaft 3, an eccentric cam 27 in which the shaft center of the inner peripheral shaft hole and the shaft center of the outer peripheral shaft are eccentrically fitted is fitted and fixed with a screw 28. rod 29
However, the thrust casing 31 is fixed to the main shaft 3 with the screw 30.

A swing shaft 32 is rotatably supported, and the free end of the rod 2T is connected to a step screw 35 in an arcuate elongated hole 34 of a swing arm 33 fixed to one end of the swing shaft 32. It is pivotally mounted with a latch 37 with a washer 36 so that its movement can be adjusted freely. Further, another swinging arm 38 is fixed to the other end of the swinging shaft 32, and the free end of this swinging arm 38 and the bell crank 2
Each end of the link 39 is connected to the upper free end of the link 39 with a stepped screw 4.
0 and 41, respectively. By doing this, when the main shaft 3 rotates, the swing shaft 32 reciprocates via the Shirorad 29 and the swing arm 33 due to the eccentric action of the eccentric cam 27. As shown in Figure 4, the Velcla/Li 24 moves towards the swaying tide.
Insert the hook 39 into the swing shaft 32 from the screw hole 42 of the swing arm 3B.

4 is configured to stop swinging. Furthermore, a protruding shaft 45 pivotally connected to the spring receiver 14 is engaged with a shaft hole 44 provided at the free end of the side of the bell crank 24, and the shaft hole 44 is engaged with the shaft hole 44 provided at the free end of the side of the bell crank 24. The presser bar 9 and the presser foot 12 are configured to move up and down. By changing the pivot position of the rod 29 with respect to the elongated hole 34, the vertical motion of the presser foot 12 is adjusted, and by stopping the bell crank 24 as described above, the vertical motion of the presser foot 12 is adjusted.

えば２ｒｒＩＴｒｌと５ｒｒ［［ｎとの間で変化する。The operation of the automatic sewing machine configured as described above will first be described for a sewn product having plain stitches and step stitches in one sewing turn. In this case, one end of the link 39 is pivotally connected to a screw hole 42 at the free end of the swing arm 38 with a stepped screw 41. When the motor is started by passing the upper thread and bobbin thread and pressing the cloth with the presser foot 12, the main shaft 3 rotates and the needle 6 operates, and the eccentric cam 2T rotates, causing the rod 29 to reciprocate due to its eccentric action. and the swing shaft 32 via the swing arm 33.
rotates back and forth. This rotation is caused by the swing arm 38 and the link 3.
9 to the bell crank 24, and the bell turns from A to Ir1, resting at 1-75. A shaft hole 44 provided at the other free end of the bell crank 24
Since the protruding shaft 45 is engaged with the bell franchise 2,
4, and this is converted into the vertical movement of the fixed presser foot shaft 9, and the presser foot shaft 9 moves up and down while sliding the rollers 49 of the stepped screw 47 up and down along the long groove 52. . Therefore, the presser foot 12 also moves up and down. in this case,
The compression coil spring 26 presses the spring shaft 22 downward, and the L fitting 23 and the bell crank 24 are connected to the stepped screw 25.
, the fulcrum position of the bell crank 24 is adjusted by rotating the adjusting screw 21. In addition,
The timing of the vertical movement of the presser foot 12 relative to the vertical movement of the needle 6 is determined by the fixed phase of the eccentric cam 2T with respect to the main shaft 3. Further, the vertical movement of the presser foot 12 is adjusted by moving the rod 29 along the elongated hole 34 of the swing arm 33 and fixing it. In other words, if the pivoting portion of the rod 29 is brought closer to the swinging shaft 32, the swinging arm 33 can be moved closer.
The swing angle of the presser foot 12 increases, and the vertical motion of the presser foot 12 changes, for example, between 2rrITrl and 5rr[[n.

When the main shaft 3 is pivoted by a stepped screw 41 into a screw hole 43 bored in the shaft center of the main shaft 3, the swing shaft 32 is rotated in the same manner as described above.
rotates back and forth, but the link 39 is +ltl of the swing shaft 32.

する。As is clear from the above description, according to the present invention, in the presser foot device of an automatic tying sewing machine, a machine 4Fj for converting the rotation of the main drum 1 into vertical movement of the presser foot is provided in the presser foot. By providing a mechanism for switching the vertical motion between an adjustable state of 1 t and a zero state, it is possible to sew plain stitches even on a workpiece that has both plain stitches and step stitches in one sewing pattern. Even if the material is to be sewn with a chisel, the appropriate presser foot height can be set, so the presser foot does not ridge over the multi-layered parts, skipped stitches, or shin holes occur, ensuring excellent sewing at all times. Performance can be ensured, and the versatility of the sewing machine is improved since there is no need to use different models depending on the item to be sewn.
