Since the configuration for switching between normal sewing and embroidery sewing is the same as that disclosed in Japanese Patent Laid-Open No. 2002-237478, which is a publicly known document, the details thereof are omitted.
The sewing machine frame 90 is composed of a free arm bed 94 that houses the above-described seam capturing part and cloth feeding part, a removable auxiliary floor part 97, and a bed part 99. These upper surfaces are kept at the same level, The bed upper surface 91 is formed. This bed upper surface 91 becomes a work surface at the time of sewing.
By removing the removable auxiliary floor portion 97, the free arm bed 94 is configured to enable sewing as a free arm such as cylindrical sewing.
As shown in the drawing, the width direction of the sewing machine body is the X direction, and the depth direction of the sewing machine body is the Y direction.

2 is a perspective view of the embroidery sewing machine according to the present invention as seen from the rear side. As shown in FIG. 2, the sewing machine frame 90 has the embroidery device 1 on the base B. Detachable on top. Since the detachable configuration is the same as that described in Japanese Patent Laid-Open No. 2002-237478, which is a publicly known document, details are omitted.
The sewing machine frame 90 is provided with an attachment detection means 71 for arranging a photocoupler and detecting that the embroidery device 1 is attached. As another form of the attachment detection means 71, it is also possible to use a microswitch arranged on the base B as a contact type detection means.
The embroidery device 1 is composed of two parts: an X-direction moving mechanism 4 fixed on the base of the sewing machine, and a Y-direction moving mechanism 11 that rotates with respect to the X-direction moving mechanism 4.
The embroidery device 1 houses an X-direction moving mechanism 4 and a Y-direction moving mechanism 11 that is rotatably connected to the X-direction moving mechanism 4. The Y-direction moving mechanism 11 is disposed on the X-direction moving mechanism, and is located at a storage position that coincides with the X-direction moving mechanism 4 of the embroidery device 1. The upper surface 10 of the embroidery device 1 is also at the same level as the bed upper surface 91, and forms a flat surface that is continuous with the bed upper surface 91.

The Y-direction moving mechanism 11 can be rotated from the storage position. As shown in FIG. 3, the Y-direction moving mechanism 11 is rotated to a position orthogonal to the mounted X-direction moving mechanism 4, thereby It is positioned so as to protrude in the depth direction (Y direction). The mechanical structure to be positioned will be described later.
At this position, the Y-direction moving mechanism 11 is ready for embroidery sewing. This position is called an embroidery position. At this embroidery position, the embroidery frame is mounted on an embroidery frame mounting piece 19 provided on the Y-direction moving mechanism 11. Note that the position of the embroidery frame attachment piece 19 shown in FIG. 3 is the storage end located at the end, and is not a position suitable for mounting the embroidery frame. For this reason, it is desirable to move to a position where it can be mounted by operation.
As will be described later, the Y-direction moving mechanism 11 is connected to an X-direction moving mechanism 4 housed in the embroidery device 1, and is moved by the X-direction moving mechanism 4 in the width direction (X direction) of the sewing machine body. The frame attachment piece 19 is moved in the Y direction, and the embroidery frame attached here is moved in the Y direction. The embroidery frame is moved in the XY directions by the operations of the X direction moving mechanism 4 and the Y direction moving mechanism 11 to perform embroidery.
The embroidery frame mounting piece 19 is provided with an embroidery frame sensor 8 (not shown), and is configured to output a signal to that effect when the embroidery frame is mounted. The embroidery frame sensor 8 may be configured to output a signal for identifying the type of the embroidery frame.

As shown in FIG. 2, the storage position is a storage position for storing the Y-direction moving mechanism 11, and when the Y-direction moving mechanism 11 is rotated and stored as shown in FIGS. The mechanism 11 coincides with the X-direction moving mechanism 4, and the upper surface of the Y-direction moving mechanism 11 is substantially the same level as the bed upper surface 91.
The Y-direction moving mechanism 11 is connected to the X-direction moving mechanism 4 and moves in the X direction.
A gap 36 is provided between the free arm bed 94 and the attached embroidery device 1 as shown in FIG. 2, and this gap 36 is free for both normal sewing and frame embroidery sewing even when the sewing machine is attached. Arm sewing function is secured. It is also possible to provide an adapter or the like for making the gap 36 flush with the bed upper surface 91.

  The Y-direction moving mechanism 11 has the arm upright 96 side as a base 12, the base 12 side is connected to the X-direction moving mechanism 4, rotates around the base 12 side as an axis, and the tip 12 a side opens and protrudes in the Y direction. Is configured to do. By positioning the Y-direction moving mechanism 11 on the arm upright 96 side, the arm upstand 96 can be prevented from interfering with the embroidery frame at the rotated embroidery position, so that it is closest to the arm upright 96. The distance in the X direction can be increased, and as a result, the embroidery frame can be increased by increasing the embroidery area.

The interior of the embroidery device 1 will be described with reference to FIGS.
As shown in FIGS. 4 and 5, the X carriage 40 of the X direction moving mechanism 4 is configured to move on the two X guide shafts 41 and 41 and is fixed to the drive belt 45. The drive belt 45 is driven by an X motor 46, whereby the X carriage 40 moves in the X direction.

The Y-direction moving mechanism 11 has a Y guard rail 13, and a Y carriage 14 moves on the Y guard rail 13. The embroidery frame mounting piece 19 is mounted on the Y carriage 14, and an embroidery frame (not shown) is mounted on the embroidery frame mounting piece 19.
The Y carriage 14 is fixed to a Y drive belt 18 provided on the lower side of the Y guard rail 13 and is moved by driving the Y drive belt 18.
The Y drive belt 18 is hung between a Y drive gear driven by the Y motor 15 and a Y pulley disposed at the tip of the Y guard rail 13, and is configured to rotate by driving the Y motor 15. ing.

The base portion 12 of the Y-direction moving mechanism 11, that is, the base portion 12 of the Y guard rail 13 is coupled to the connecting portion 2, and is rotated and positioned about the base portion 12 until it is orthogonal to the X moving mechanism 4. The The connecting portion 2 includes a rotating substrate 20, and the Y-direction moving mechanism 11 is rotated by rotating the rotating substrate 20.
In FIG. 4, the Y-direction moving mechanism 11 is at an orthogonal position protruding from the bed back surface 93 in the direction of approximately 90 degrees, and this position is an embroidery position and an embroidery position. When embroidery is not performed, the Y-direction moving mechanism 11 is rotated about 90 degrees and stored on the X-direction moving mechanism. This state is the storage position.

The connecting portion 2 is mounted on the X carriage 40.
As shown in FIGS. 6 to 8, the connecting portion 2 includes a rotating substrate 20 and a rotating shaft 21, and the rotating shaft 21 is inserted into a rotating hole 42 provided in the X carriage 40 and rotates. It is configured as follows.
A square-shaped protrusion base 26 is provided on the lower side of the rotating substrate 20, and a pair of V-shaped fixing protrusions 22 and 22 are formed on one end side and the other end side of the lower end thereof.
The X carriage 40 is provided with V-shaped grooves 43 and 43 into which the pair of V-shaped fixing protrusions 22 and 22 are fitted, and V-shaped grooves 44 and 44 at positions orthogonal to the grooves. .
The rotating shaft 21 is normally pushed downward by a spring 23 as a proximity means, and the pair of fixing protrusions 22 and 22 are inserted into the protruding fixing groove 43 or the storing fixing groove 44, and A force is applied in the approaching direction by the pressing force of the spring 23, and the rotating substrate 20 is fixed on the X carriage 40. In this state, the Y-direction moving mechanism 11 is not rotated.

As shown in FIG. 8, the X carriage 40 is provided with overhanging fixing grooves 43, 43 and storage fixing grooves 44, 44 having an angle of 90 degrees, and is opposed to the rotating substrate 20 by 180 degrees. The provided pair of fixing protrusions 22 and 22 are respectively inserted and inserted.
When the Y guard rail 13 protrudes in the Y direction and comes to a stop position where embroidery is executed, the fixing protrusions 22 and 22 are inserted into the fixing grooves 43 and 43 when extended, and the Y guard rail 13 is in the storage position where it is stored. Sometimes, the fixing protrusions 22 and 22 are configured to be inserted into the fixing grooves 44 and 44 when stored.
A storage sensor 7 is provided in the vicinity of the storage fixing groove 44, and detects the protrusion base 26 to detect that the Y-direction moving mechanism 11 is in the storage position.

  The rotating substrate 20 provided in the connecting portion 2 to which the Y-direction moving mechanism 11 is connected is lifted up against the depressing force of the spring 23 by an operation of pulling up the rotating substrate 20. The engagement between the projections 22 and 22 and the overhanging fixing groove 43 or the storing fixing groove 44 is released, and the Y-direction moving mechanism 11 can rotate.

  On the X carriage 40, rotating springs 5 and 5 are provided. The rotation spring 5 presses the side wall of the protrusion base 26 to release the rotation substrate 20 when the fixing protrusions 22, 22 and the fixed groove 43 when extended or the fixed groove 44 when retracted are released. This is for rotating a predetermined amount.

As shown in FIG. 9, when the Y-direction moving mechanism 11 is in the storage position in which it is stored, the fixing protrusions 22, 22 are inserted into the storage fixing grooves 44, 44, and the rotating spring 5 is the protrusion base. 26 is disposed at a position where it abuts against the embroidery sewing position and is pressed toward the embroidery sewing position. This pressing direction is a direction in which the Y-direction moving mechanism 11 protrudes toward the bed rear surface 93 side, that is, a direction in which the Y-direction moving mechanism 11 is rotated in the direction of the embroidery sewing position for executing embroidery.
When the Y-direction moving mechanism 11 is in the embroidery position, the other rotation spring 5 ′ has the fixing protrusions 22, 22 fitted in the fixing grooves 43, 43, and comes into contact with the protrusion base 26. The Y-direction moving mechanism 11 is pressed in a direction that rotates in the storage position direction.

As shown in FIG. 2, when the Y-direction moving mechanism 11 is in the storage position described above, the fixing protrusion 22 is in a state of being fitted into the storage fixing groove 44 as shown in FIG. 9A. When the rotating shaft 21 is pushed up by operation from this state, the engagement between the fixing protrusions 22 and 22 and the grooves 44 and 44 is released, and at this time, the protrusion base 26 is pushed by the rotating spring 5 at the same time. The moving substrate 2 rotates by a predetermined amount.
This state is shown in FIG. At this time, the Y-direction moving mechanism 11 rotates and slightly protrudes from the storage unit 31. Then, by inserting a finger into the gap with the storage portion 31 and manually rotating the arm 1, it can be easily set at the embroidery position.
Further, as shown in FIG. 9 (B), the fixing protrusion 22 is retained and held on the flat upper surface of the X carriage, so that it does not re-fit into the groove 44. Accordingly, when the one end is operated and pulled up, the X carriage can be smoothly rotated on the flat upper surface.
The above operation is the same when returning from the embroiderable position where the fixing protrusions 22 and 22 and the grooves 43 and 43 are fitted to the storage position.
Since it is configured in this manner, the Y-direction moving mechanism 11 is not in a stable state in a state where it is not engaged with either of the grooves 43 or 44, and is held in either one. Accordingly, the position of the Y-direction moving mechanism 11 is mechanically determined as the storage position or the embroidery position. For this reason, it is possible to detect the embroidery position by not only the above-described storage sensor 8 being the storage position.

In the above configuration, it is not necessary to remove the embroidery enabling device 1 when shifting from embroidery sewing to normal sewing. When the embroidery device 1 is mounted and normal sewing is performed, the Y-direction moving mechanism 11 is set to the storage position, which is the position on the X-direction moving mechanism 4, as shown in FIG. At this time, since the arm upper surface 10 of the Y-direction moving mechanism 11 is flush with the bed upper surface 91, the cloth upper surface 91 is enlarged as an auxiliary table without obstructing the cloth operation sewing work. Convenience is improved.
At the time of embroidery, as shown in FIG. 3, the Y-direction moving mechanism 11 is pulled out approximately 90 degrees, and is pulled out perpendicular to the X-direction moving mechanism 4, and an embroidery frame (not shown) is fixed to the embroidery frame mounting piece 19 to execute embroidery. . Since the Y-direction moving mechanism 11 is not housed in the machine frame, the Y-direction moving mechanism 11 can be enlarged regardless of the length of the sewing machine body in the Y direction. And large embroidery can be realized. Since the length of the Y-direction moving mechanism 11 can be attached and detached, it can be of any length.
Further, as the Y-direction moving mechanism 11, by increasing the length of the free arm bed along the length direction, the movement amount in the Y direction is increased and further increased, or the movement amount in the Y direction is increased. In order to make the entire apparatus compact, an amplifying unit can be provided in the Y-direction moving mechanism 11.
JP-A-2001-17765 by the applicant of the present application can be used for details of the amplifying means. Details are omitted.
Further, since the Y-direction moving mechanism 11 is securely fixed at the storage position and the embroidery position by the mechanism of the connecting portion 2 described above, it is possible to obtain a reliable operation. If the Y-direction moving mechanism 11 is pulled up and the rotary shaft 21 is pulled up, the engagement between the fixing projection 22 and the grooves 43 and 44 is released, and at the same time, the projection base 26 is pushed by the rotary spring 5, The rotating substrate 2 rotates by a predetermined amount. Therefore, the turning operation of the arm 1 is simple. Further, since the fixing protrusion 22 is locked on the flat upper surface of the X carriage, the fixing protrusion 22 is not re-fitted into the grooves 43 and 44, and can be rotated if it is rotated once, and the operability is good. .

  In the above configuration, as shown in FIG. 10, the micro switch 6 can be further provided so that the Y-direction moving mechanism 11 can be detected at the embroidery position. The microswitch 6 is mounted on the X carriage 40 and is operated by a striker surface 60 formed to project downward on the lower side of the base 12 of the arm 1.

The striker surface 60 turns on the microswitch 6 when the Y-direction moving mechanism 11 is in the embroidery position and the rotating shaft 21 is pushed down to engage the fixing protrusion 22 and the groove 43. ing. The microswitch 6 is configured to be turned off at the position where the rotation shaft 21 is raised.
When the Y-direction moving mechanism 11 is not in the embroidery position, the striker surface 60 is disengaged from the position of the microswitch 6, so that the microswitch 6 is turned off.

  In the above configuration, as shown in FIG. 10, when the Y-direction moving mechanism 11 is in the embroidery position and the rotating shaft 21 is pushed down and the fixing projection 22 and the groove 43 are engaged, the microswitch 6 Is turned on. On the other hand, when the rotating shaft 21 is pushed up, the microswitch 6 is turned off. When the Y-direction moving mechanism 11 is not in the embroidery position, the microswitch 6 is turned off.

The drive control of the Y motor 15 and the X motor 46 can be performed according to the signal of the micro switch 6.
The microswitch 6 that detects the embroidery position rotated by the Y-direction moving mechanism 11 and the storage sensor 7 constitute a position detecting means 70.
