The configuration was adopted.

[Operation] With this configuration, parts such as the body after button attachment or buttonhole are finished are laid on the cloth stacking device, and semi-finished products or long objects are discharged out of the sewing machine by the discharge mechanism. Thus, the sewing operation can be performed continuously.

[Embodiment] Hereinafter, the embodiment of the present invention will be described in detail with reference to the drawings.

1 and 2 show the configuration of an indexer with preset according to an embodiment of the present invention.

In both figures, reference numeral 6 denotes a sewing machine main body that performs button attachment or buttonhole sewing, and is provided on the table 7.

A cloth transport mechanism 2 for moving the cloth 10 in the direction of arrow B at the pitch of a button or a buttonhole with respect to the sewing machine body 6 is provided.

In front of the cloth transport mechanism 2,
A cloth supply mechanism 1 for supplying 10 is provided.

Further, in front of the sewing machine main body 6, near the side of the cloth transport mechanism 2 in the direction B (cloth transport direction), there is provided a cloth discharge mechanism 3 for discharging the cloth 10 after buttoning or boring to the outside of the apparatus in the direction of arrow C. Provided. The cloth discharging mechanism 3 is composed of pulleys 33 and 34 on which a belt 32 is stretched, a motor 31 as a driving source, and a table 35. By driving the motor 31, the pulley 33 is rotated in the direction of arrow D in FIG. It is designed to run around. Then, the cloth 10 after the sewing is completed enters between the belt 32 and the table 35 with the movement of the cloth transport mechanism in the direction B, and the belt 32 runs by the drive of the motor 31 so that the cloth is subjected to friction between the table 35 and the belt 32. Is sent in the direction of arrow C and discharged from above the indexer.

Here, in the indexer of the present embodiment, a mode in which the cloth discharging mechanism 3 is driven and a mode in which the cloth discharging mechanism 3 is not driven can be selected. For this purpose, an operation panel 4 provided on the sewing machine main body 6 is provided with a mode selection switch 5 for selecting the above-mentioned mode. It is to be noted that the number and pitch of buttons or holes are set as desired by operating key switches (not shown) on the operation panel 4.

Next, the operation of the thus configured indexer of the present embodiment will be described below.

First, an operator presses a start switch (not shown) after setting a cloth on the cloth supply mechanism 1. Thereby, the cloth supply mechanism 1
Is driven to transport the cloth 10 in the direction of arrow A, and the cloth transport mechanism 2
Hand over to

Next, the cloth conveying mechanism 2 conveys the cloth 10 in the direction of the arrow B, and stops the conveyance when the portion where the first button setting or boring is performed reaches the position of the needle for sewing the sewing machine body 6.
Then, the sewing machine body 6 is driven to perform the first buttoning or boring. In the case of attaching buttons, a button feeder (not shown) supplies the buttons. When the operation is completed, the cloth conveying mechanism 2 conveys the cloth 10 in the direction B by a predetermined pitch, and the sewing of the button or the buttonhole is automatically performed sequentially by driving the sewing machine main body 6 again.

Here, when the cloth 10 is the semi-finished product 9 shown in FIG. 4 to the long object 11 shown in FIG. 3, the mode in which the cloth discharge mechanism 3 is driven by the mode selection switch 5 is set in advance. When the sewing is completed, the clamp 10 on the cloth 10 by the cloth transport mechanism 2 is released, and then the cloth discharge mechanism 3 is driven to discharge the cloth 10 after the sewing is completed in the direction of arrow C.

If the cloth 10 is a part such as a body indicated by reference numeral 8 in FIG. 3, the cloth 5 is set to a mode in which the cloth discharge mechanism 3 is not driven by the switch 5, so that the cloth 10
The cloth transport mechanism 2 moves in the direction opposite to the direction B, returns to the initial position, and the cloth 10 is automatically stacked on the cloth stacking mechanism.

As described above, according to the indexer with preset of the present embodiment, the cloth having the cloth discharging mechanism 3 is provided, and when the cloth to be buttoned or holed is a semi-finished product or a long one, the cloth after the sewing is completed is moved in the C direction. Since discharge can be performed, buttoning or boring can be performed continuously, the operator can take charge of a large number of indexers, and the productivity of sewing products can be significantly improved.

In the above configuration, the cloth discharge mechanism 3 can of course be constituted by other means such as an air cylinder.
