- a pair of holes 52c and 52d are formed on the upper wall of the holding frame 52 in correspondence with the magnets 53 and the lever members 61, and the operation parts 61a and 61b can protrude outside from the holes 52c and 52d, respectively. It has become. Therefore, when the magnet 53 is at the attraction position, the operation portion 61b projects outside, and when the magnet 53 is at the non-attraction position, the operation portion 61a projects outside.
- the position of each magnet 53 attached to the holding frame 52 by the magnet position switching means 55 is separated from the attraction position shown in FIG. 27 where the magnet 53 is attracted to the support frame 51 and from the attraction position. This is switched over to the non-sucking position shown in FIG.
- the non-sucking position holding means 56 has a disc spring 62 externally mounted on the pivot pin 60 inside the holding frame 52.
- the lever member 61 is pressed against the inner surface of the holding frame 52 by the urging force of the disc spring 62, and a frictional force acts between the lever member 61 and the holding frame 52. As a result, the lever member 61 starts rotating and the magnet 53 is held at the non-sucking position.
- the cloth holding device 50 when holding the work cloth W, the work cloth W is placed on the support frame 51, and the holding frame 52 is placed on the support member 51 so as to sandwich the force cloth W.
- the magnet 53 when the magnet 53 is switched from the non-adsorption position to the adsorption position by the magnet position switching means 55, the magnet 53 is adsorbed to the support frame 51.
- the magnet holding member 54 at one end of the lever member 61 has a first engagement portion 63 that engages with the upper wall of the holding frame 51 from outside, and a second engagement portion 63 that engages with the upper wall of the holding frame 51 from inside.
- An engagement portion 64 is formed.
- the magnet holding member 54 of the magnet 53 attracted to the support frame 51 presses the holding frame 52 against the support frame 51 via the first engagement portion 63. Also, if the second engaging portion 64 engages with the upper wall of the holding frame 51 to place the magnet 53 in the non-sucking position, and in this state, the lever member 61 is prevented from projecting below the holding frame 52. Since it does not rotate any more clockwise in the figure, the force S can be stably placed on the support frame 52 with the presser frame 52 sandwiching the work cloth W when holding the Karoe cloth W.
- the work cloth W is extended while being positioned, and further, the work cloth W is further extended.
- the magnet position switching means 55 has the lever member 61 and the operation parts 61a and 61b, the lever member 61 is rotated by operating the operation parts 61a and 61b provided at both ends of the lever member 61.
- the magnet 53 connected to one end of the lever member 61 can be easily switched between a suction position and a non-suction position.
- the support frame and the presser frame may be changed as follows.
- the support member will not be described, the support member may be modified similarly to the support frame.
- a non-slip portion 71a is formed in a portion of the support frame 71 facing the holding frame 70.
- a non-slip portion 72a is formed in a portion of the holding frame 72 facing the support frame 73.
- non-slip portions 74a and 75a are formed on a portion of the holding frame 74 facing the support frame 75 and a portion of the holding frame 75 facing the holding frame 74, respectively. .
- the non-slip portions 71a, 72a, 74a, 75a are formed by forming a plurality of minute irregularities. As a result, the work cloth held on the support frames 71, 73, 75 by the upper frames 70, 72, 74 becomes less slippery due to the non-slip portion, and the work cloth is extended to form the support frames 71, 73, 75. On the other hand, it is possible to more reliably maintain the state of positioning at a desired position.
- the magnet holding member is made of synthetic resin, but may be a member made of, for example, iron as a magnetic material.
- the magnet holding member acts as a yoke (yoke) forming the magnetic circuit, the magnet holding force can be increased, and the force-pulling cloth W can be held more reliably.
- the attracting means may be constituted only by a magnet.
- the magnet is formed in a cylindrical shape having a protrusion of about lmm at the tip thereof, and the protrusion is configured to engage with the engagement hole.
- the spacer 38 when the spacer 38 is provided between the operation unit 34b and the presser frame 32 and is integrally provided on the magnet holding member 34 (see FIGS. 33 and 34),
- the holding frame 32 is pressed against the support frame 31 via the magnet holding member 34 of the magnet 33 attracted by the magnet 31 and the spacer 38 via the spacer 38. That is, the magnetic attractive force of the magnet 33 to the support frame 31 is
- the pressing frame 32 is transmitted from the gnet holding member 34 to the pressing frame 32, and the pressing frame 32 can be pressed against the supporting frame 31 at the periphery of the magnet 33.
- the cloth holding device 10 may be partially changed as follows.
- the embroidery sewing machine can be applied as a device for holding a work cloth to be used for sewing, thereby improving sewing and sewing position accuracy, shortening a series of sewing work times, and the like.
- the cloth holding device 20 may also be partially modified as described above.
- the support member may be formed in a frame shape having substantially the same shape and the same size as the holding frame 22.
- the cloth holding device 30 may be partially changed as follows. 1] The shape and size of the support frame 31 and the holding frame 32, the shape, size and number of the magnet 33 and the magnet holding member 34, the arrangement of the magnet 33, the magnetic force, and the like can be appropriately changed. 2] In the non-sucking position holding means 36, in addition to the configuration having the plate-like member 37, the engaged portion provided on the magnet holding member 34 engages with the engaging portion provided on the holding frame 32.
- Non-sucking such as a configuration in which the magnet 33 is held in the non-sucking position, and a configuration in which the magnet 33 is held in the non-sucking position simply by friction between the magnet holding member 34 and the inner surface of the presser frame 32 in contact therewith.
- Position holding means can be applied.
- the cloth holding device 40 may be partially modified as described above. Further, the support member may be formed in a frame shape having substantially the same size as the holding frame 42.
- the cloth holding device 50 may be partially changed as follows. 1] The shape and size of the support frame 51 and the holding frame 52, the shape and size and number of the magnet 53 and the lever member 61 (magnet holding member 54), the arrangement of the magnet 53, the magnetic force, etc. It can be changed as appropriate.
- non-sucking position holding means 56 various biasing members such as a compression coil panel may be applied in addition to the plate panel 62, and in addition to the configuration having the plate panel 62, simply a magnet holding member
- Various non-suction position holding means such as a configuration for holding the magnet 53 at the non-suction position by friction between the 54 and the inner surface of the presser frame 52 that comes into contact with it, can be applied.
- the cloth holding device according to the present invention is useful as a cloth holder for a printer that prints on an embroidery frame of an embroidery sewing machine or a kamen cloth.
