BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for sewing a peripheral edge of a slipper.

[0002]

2. Description of the Related Art In a slipper, a peripheral edge of an instep is sandwiched between a midsole and a grounded bottom, and the peripheral edge of the bottom is sewn to connect the midsole and the grounded bottom. A dedicated sewing machine for sewing the peripheral edges of the insole and the grounded bottom has already been developed and used. In this sewing machine, a lower arm and an upper arm are arranged so as to face each other. A bobbin thread is built in the tip of the lower arm, and a sewing needle that reciprocates up and down is provided in the upper arm. On the lower arm,
Put the slipper upside down and insert the needle of the upper arm into the lower arm to sew the slipper. In order to sew the peripheral edge of the slipper, the slipper is manually moved to the tip of the lower arm. The sewn slippers adhere the periphery of the instep to the lower surface of the insole, stack the grounding bottom on the lower surface of this insole, and turn it upside down, that is, stacking the grounding bottom on the insole. Then, sew the peripheral edge. The slipper that moves along the tip of the lower arm can be easily held by temporarily adhering the middle bottom and the grounded bottom.

A sewing machine that sewes the periphery of a slipper by this method requires considerable skill. This is because it is difficult to sew exactly along the periphery of the slippers. The present inventor has developed a device for automatically sewing the periphery of a slipper in order to solve this drawback. This device includes a holder for temporarily fixing the slipper and a moving member for moving the holder in the X-axis and Y-axis directions. The holder is arranged horizontally by temporarily stacking the insole to which the upper skin is adhered and the grounding bottom and temporarily fixing them. The moving means moves the holder in the X-axis and Y-axis directions to move the peripheral edge of the temporarily fixed slipper to the tip of the lower arm.

[0004]

This device has a feature that when the slipper is set in the holder, the periphery of the slipper can be automatically sewn. However, this device has a drawback that the peripheral edge of the slipper cannot be accurately sewn and the distance between the peripheral edge and the sewing position is partially changed. Especially,
When sewing a slipper with a hard upper, there was a drawback that the sewing position was easily displaced. This is because the lower arm 2 inserted inside the upper 1 shifts the position of the slipper 4 as shown in FIG. If the width of the lower arm 2 can be made very narrow, this drawback can be solved. However, the lower arm 2
Since the bobbin wound with the bobbin is stored, the width cannot be reduced so much. Therefore, when the lower arm 2 is inserted into the upper 1 and the periphery of the upper 1 is sewn, the lower arm 2 pushes the upper 1 outward as shown by the arrow A to shift the temporary fixing position. Further, to trouble, in order to sew along the peripheral edge of the bottom, as shown in FIG. 1, one side of the lower arm 2 projects outward from the outer peripheral edge of the bottom. For this reason, the holder 5 is arranged outside the upper 1 and the slipper 4
Cannot be held, and the lower arm 2 inserted into the upper 1 cannot prevent the slipper 4 from temporarily shifting its position. The holder 5 should be located outside the bottom and the outside of the upper 1 should be open.

The present invention was developed with the object of resolving this drawback. An important object of the present invention is to manufacture a slipper which prevents displacement of the slipper and enables accurate sewing of the peripheral edge of the bottom. To provide the equipment.

[0006]

In order to achieve the above-mentioned object, a slipper manufacturing apparatus of the present invention has the following structure. (A) The slipper manufacturing apparatus includes a holder 5 for temporarily fixing the slipper 4, a sewing machine 6 for sewing the peripheral edge of the slipper 4 held by the holder 5, and the slipper 4 held by the holder 5 for the sewing position of the sewing machine 6. And moving means for moving to. (B) The sewing machine 6 is provided with a lower arm 2 provided on the lower surface of a slipper 4 which is held upside down, and an upper arm 3 provided above the lower arm 2 and having sewing needles that move up and down. (C) The holder 5 is located below the holding frame 5A that holds the peripheral edge of the slipper 4 and includes an elastic holding member. (D) The elastic holding members 7 are arranged on both sides of the upper-sewn portion of the slipper 4. (E) The elastic body 8 is connected to the elastic holding member 7. (F) The elastic body 8 elastically presses the elastic holding member 7 against the side edge of the slipper 4.

[0007]

The slipper manufacturing apparatus of the present invention sewes the peripheral edge of the bottom as follows. However, in order to make the manufacturing process of the slipper easy to understand, the process not using the slipper manufacturing device is also described. The peripheral edge of the upper 1 is adhered to the lower surface of the insole 4A. The grounding bottom 4B is laminated on the insole 4A to which the upper 1 is adhered. In this state, it is possible to temporarily bond the middle bottom 4A and the ground bottom 4B. The slippers 4 are turned upside down and set on the holder 5 with the upper 1 facing downward. The holder 5 holds the peripheral edge of the bottom of the slipper 4 with a holding frame 5A.
, And both sides of the upper 1 are held by elastic holding members 7.
The elastic holding member 7 elastically presses both sides of the upper 1 to prevent the slipper 4 from being displaced. The holding frame 5A is carried into the sewing position of the sewing machine 6. This step is performed manually or automatically. The sewing machine 6 sewes the peripheral edge of the slipper 4, and the moving means moves the holder 5 in the horizontal plane to move the peripheral edge of the bottom to the sewing position of the sewing machine 6. When the sewing of the peripheral edge of the bottom is completed, the operation of the sewing machine 6 is stopped. The holder 5 is taken out from the sewing machine 6, or the sewn slipper 4 is taken out without taking out the holder 6 and the non-sewn slipper 4 is set. The steps of are repeated to manufacture the slippers.
