It is rotatably supported.
The driving member 132 is joined to the rotating shaft 22 of the driving member support 20 at one end thereof and is rotatably connected to the driven member 133 at the other end. Specifically, the other end portion side of the driving member 132 is formed to extend obliquely downward, and an opening penetrating vertically is formed at the tip portion. A substantially cylindrical first connecting member 310 that protrudes upward from the end of the driven member 133 is inserted into the opening, and the driving member 132 is inserted into the driven member 133 via the first connecting member 310. It is the structure connected to a rotation.

  The driven member 133 is a substantially L-shaped member in plan view that moves according to the rotation of the driving member 132. As described above, the first connecting member 310 is provided at one end of the driven member 133, and the driven member 133 is rotatably connected to the driving member 132. The second end of the driven member 133 is provided with a second connecting member 311 having a substantially cylindrical shape, and is rotatably connected to the rotating member 134 via the second connecting member 311. . The mounting base 12 is attached to a portion extending laterally from the other end of the driven member 133.

  The rotating member 134 is joined to the rotating shaft 32 of the rotating member support 30 at one end, and is rotatably connected to the driven member 133 at the other end. Specifically, the other end portion side of the rotating member 134 is formed so as to extend obliquely downward, and an opening penetrating vertically is formed at a tip portion thereof. A substantially cylindrical second connecting member 311 that protrudes upward from the end of the driven member 133 is inserted into the opening, and the rotating member 134 is inserted through the second connecting member 311. And are connected in a rotatable manner.

  Here, as shown in FIG. 8, a straight line connecting both ends of the driving member 132, that is, a joint point between the driving member 132 and the rotating shaft 22 of the driving member support portion 20, and the driving member 132 and the first connecting member 310. Let L1 be a straight line connecting the connection points. Then, a straight line connecting both ends of the rotating member 134, that is, a straight line connecting a joint point between the rotating member 134 and the rotating shaft 32 of the rotating member support 30 and a connecting point between the rotating member 134 and the second connecting member 311. Is L2. A straight line connecting both ends of the driven member 133, that is, a straight line connecting the joining point of the first connecting member 310 and the joining point of the second connecting member 311 is defined as L3.

Then, when viewed in plan, the fixed member 131, the driving member 132, the driven member 133, and the rotating member 134 are connected so that the straight line L1 and the straight line L2 are parallel, and the straight line L3 and the straight line L4 are parallel. Thus, a parallel four-joint link mechanism 13 is configured.

  Further, an auxiliary member 312 is rotatably connected to a substantially central portion in the longitudinal direction of the driving member 132 and a substantially central portion in the longitudinal direction of the rotating member 134. When the rotary motor 141 is driven, as shown in FIG. 8, the driving member 132 starts to rotate counterclockwise in a substantially horizontal plane around the joint portion with the rotating shaft 22, and according to the rotation of the driving member 132, The driven member 133 moves backward. As the driven member 133 moves, the rotating member 134 also rotates about the joint portion with the rotating shaft 32. However, due to the nature of the parallel four-bar linkage mechanism 13, the straight line L3 and the straight line L4 are always viewed in plan view. Move while maintaining parallel state. Accordingly, the mounting base 12 moves while maintaining the orientation at the button set position, that is, in a state where the longitudinal direction thereof is along the front-rear direction, while the button holding pins 15 and 16 are positioned forward.

Thereafter, the driving member 132, the driven member 133, and the rotating member 134 reach a so-called dead point where they are aligned on the same straight line L in plan view. In this state, in the general parallel four-bar linkage mechanism 13, the connection point between the driven member 133 and the rotating member 134 can be located on either side of the straight line L. Since the auxiliary member 312 is attached to the parallel four-bar linkage mechanism 13 shown in the form, the connecting point between the driven member 133 and the rotating member 134 does not lie on the right side with respect to the straight line L, and passes through the dead point. can do.
Thereafter, the mount 12 moves to the vicinity of the button gripping device 5 at the button supply position (see FIG. 7), and the button gripping arms 51L and 51R grip the button B between the button gripping portions 52L and 52R facing left and right. This completes the button supply operation.

<Operation for adjusting the distance between button holding pins>
Next, the interval adjustment operation of the button holding pins 15 and 16 in the button transport device 1 will be described.
For example, when there are two threading holes of a button used for sewing, it is assumed that the distance between the button holding pins 15 and 16 is as shown in FIG. If the button to be sewn next is larger than the button currently being sewn, the interval between the threading holes generally increases.
At this time, the user loosens the screw 111c and the screw 112c to release the button placement arm 111 and the button placement arm 112 from being fastened by the screw 111c and the screw 112c.
Then, the button placement arm 111 is slid back by the same distance, and the button placement arm 112 is slid forward by the same distance. Note that this sliding movement is enabled by the long holes 111a and 112a. Thereby, the space | interval between the button holding pins 15 and 16 spreads.

When the threading hole of the button used for sewing is four, the user loosens the screw 111c and the screw 112c and releases the button placement arm 111 and the button placement arm 112 from being fastened by the screw 111c and the screw 112c. Then, the button mounting arm 111 is slid back and the button mounting arm 112 is slid forward by the same distance, and the button mounting arm 111 is rotated clockwise around the screw 111c, so that the button mounting arm is rotated. 112 is rotated counterclockwise around the screw 112c. As a result, as shown in FIG. 3, the button holding pin 15 and the button holding pin 16 face each other in an oblique direction (for example, 45 ° oblique) with respect to the front-rear direction or the left-right direction across the intersection 12p. Is inserted into the threading hole on the front left side toward the button, and the button holding pin 16 is inserted into the threading hole on the front right side toward the button.
It should be noted that these interval adjustment operations are performed so that the position where the button is placed is not greatly shifted while the user looks at the intersection 12p.

<Effects of Embodiment>
According to the button-equipped sewing machine 1 in the embodiment, since the button mounting arms 111 and 112 can be moved and the distance between the button holding pins 15 and 16 can be adjusted, the button holding pins 15 are matched to the buttons used for sewing. , 16 can be changed so that a variety of buttons can be held by a single button transport device.
Thereby, it is not necessary to manufacture the button mounting base 11 in advance for each type of button used for sewing, and the cost for sewing can be suppressed. Moreover, since the quantity of the button mounting base 11 which should be prepared can be reduced, the burden of replacement work and parts management by a user can be reduced. Further, even if there is a sudden specification change during sewing, it can be dealt with by simply changing the distance between the button holding pins 15 and 16, so that the sewing is stagnant until the button mounting table 11 is newly manufactured. Therefore, the sewing efficiency can be improved.
Further, conventionally, when a button having a different size from another is used at only one place in a long sewing process, it is necessary to manufacture the button mounting table 11 for the button. Therefore, all such problems can be solved by adjusting the distance between the button holding pins 15 and 16, so that the use of resources used for manufacturing the button mounting table 11 can be suppressed, and resource saving can be achieved. Can contribute.

Further, the mounting base 12 is formed with a groove 12b along the front-rear direction and a groove 12c along the left-right direction. Since these grooves 12b, 12c have intersections 12p, these grooves 12b, 12c and intersections 12p Can be used as a center index indicating the center position of the button when the button is gripped by the button gripping device 5, and these grooves 12b, 12c and It can be moved while looking at the intersection 12p.
