Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a device for sewing the peripheral edge of a slipper.

[0002]

[Prior art]

 In the slippers, the peripheral edge of the upper is sandwiched between the midsole and the grounded bottom, and the peripheral edge of the bottom is sewn to connect the midsole and the grounded bottom. A special 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 the upper arm is provided with a sewing needle that reciprocates up and down. Place the flipped slipper on the lower arm and insert the needle of the upper arm into the lower arm to sew the slipper. In order to sew the periphery of the slipper, move the periphery of the slipper by hand to the tip of the lower arm. The slippers to be sewn are such that the periphery of the instep is glued to the lower surface of the insole, the grounding bottom is laminated on the lower surface of this insole, and this is turned upside down, that is, the grounding bottom is laminated on the insole. The peripheral edge is sewn in the state where it does. The slipper that moves along the tip of the lower arm can be easily held by temporarily adhering the middle bottom and the ground bottom.

Sewing machines that sew the peripheral edges of slippers in this manner require 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 the slipper 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. For the holder, the insole to which the upper skin is adhered and the grounding bottom are laminated, temporarily fixed and placed horizontally. 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]

[Problems to be solved by the device]

 This device has the 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. When sewing a hard upper slipper, the sewing position tends to shift. 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 defect can be eliminated. However, since the lower arm 2 accommodates the bobbin wound with the lower thread, 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, it is troublesome that in order to sew along the peripheral edge of the bottom, one side of the lower arm 2 projects outward from the outer peripheral edge of the bottom, as shown in FIG. Therefore, the holder 5 cannot be placed outside the upper 1 to hold the slipper 4, and the lower arm 2 inserted into the upper 1 shifts the temporary fixing position of the slipper 4. Can't be stopped. The holder 5 should be located outside the bottom and the outside of the upper 1 should be open.

The present invention was developed for the purpose of solving this drawback. An important object of the present invention is to prevent slipping of the slipper and to accurately sew the periphery of the bottom of the slipper. Providing manufacturing equipment.

[Action]

 The slipper manufacturing apparatus of the present invention sewes the peripheral edge of the bottom as follows. However, in order to make the slipper manufacturing process easier to understand, the process without using the slipper manufacturing equipment 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 periphery of the bottom of the slipper 4 with a holding frame 5A, and holds both sides of the upper 1 with 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 process can be done 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 slippers 4 are taken out without taking out the sewing machine 6 and the non-sewn slippers 4 are set. The steps of are repeated to manufacture the slippers.

However, the embodiments shown below exemplify a device for embodying the technical idea of the present invention, and the device of the present invention has the following materials, shapes, structures, and arrangements of the components. It is not specified in. The device of this invention can be modified in various ways within the scope of claims for utility model registration.

Further, in this specification, in order to make it easy to understand the scope of claims for utility model registration, the numbers corresponding to the members shown in the embodiments are referred to as “column for claims for utility model registration” and “the problem is solved. It is added to the members shown in the section of "means for determining" and the section of "action". However, the members shown in the scope of claims for utility model registration are by no means specified as the members of the embodiment.

The slipper manufacturing apparatus shown in FIG. 2 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 a slipper 4 held by the holder 5. And moving means for moving the sewing machine to the sewing position of the sewing machine 6.

The sewing machine 6 is provided on a lower surface of a slipper 4 which is turned upside down and held, and an upper arm having a lower arm 2 and an upper and lower sewing needle (not shown) provided above the lower arm 2. 3 and 3. The lower arm 2 incorporates a bobbin of a lower thread, and a sewing hole into which a sewing needle of the upper arm 3 is inserted is opened at the tip. A sewing needle is inserted into the sewing hole, and the bottom of the slipper 4 placed on the lower arm 2 is sewn. The upper arm 3 is disposed above the lower arm 2 so as to face the lower arm 2. The lower arm 2 contacts the lower surface of the slipper 4, but the upper arm 3 is located apart from the slipper 4 and a sewing needle provided at the tip penetrates the slipper 4 for sewing.

The holder 5 is for temporarily attaching the slipper 4 detachably and setting it at a predetermined position. That is, the holder 5 to which the slippers 4 have been temporarily fixed is carried into the sewing position, and after the sewing is completed, the holder 5 is discharged from the sewing position and the sewn slippers 4 are taken out. The one in which the holder 5 is removed from the sewing position of the sewing machine 6 and the slipper 4 is detached and attached has a feature that the supply and removal of the slipper 4 can be conveniently performed. However, it is also possible to dispose the holder 5 at the sewing position of the sewing machine 6, supply the unsewn slipper 4 to the holder 5 at this position, and take out the slipper 4 after sewing.

It is important that the holder 5 holds the slipper 4 easily and surely. In order to hold the slipper 4, the holder 5 includes a holding frame 5A and an elastic holding member 7, as shown in FIG. The elastic holding member 7 is arranged below the holding frame 5A as shown in FIG. The elastic holding members 7 elastically press both sides of the upper 1 of the slippers 4 set on the holding frame 5A to temporarily fix them. The elastic holding member 7 elastically presses both sides of the slipper 4 and moves outward when the lower arm 2 pushes the upper 1 outward. The inner shape of the elastic holding member 7 is a shape that follows the upper 1 of the slipper 4.

The elastic holding member 7 shown in FIG. 5 is connected at its upper end to the holding frame 5A via a rotating shaft so as to be rotatable in a horizontal plane. An extension spring, which is an elastic body 8, is connected to the middle of the elastic holding member 7, and the elastic holding member 7 is pressed against the slipper 4 by this extension spring. The elastic holding member 7 shown in FIG. 5 connects two tension springs. In this figure, the upper tension spring adjusts the force with which the elastic holding member 7 presses the slipper 4, and the lower tension spring holds the upper 1 of the slipper 4 on the lower surface, as shown in FIG. In this way, when the lower surface of the upper 1 of the slipper 4 is held by the tension spring connected to the elastic holding member 7, the slipper 4 can be held more reliably and the displacement can be prevented.

The holding frame 5A holds the peripheral edge of the bottom into which the slipper 4 is fitted. Therefore, the inner shape is set along the periphery of the bottom. The simplest holding frame 5A is fixed to the holder body. However, although not shown, it goes without saying that it is also possible to connect the portion holding the peripheral edge of the bottom to the holder main body so as to be able to move somewhat with a spring that is harder than the elastic holding member 7.

As shown in FIGS. 6 and 7, the holding frame 5A projects a mounting plate 5B on which the bottom of the slipper 4 with the upper face facing downward is placed. FIG. 6 shows a portion on which the front end of the slipper 4 is placed, and FIG. 7 shows a state in which the rear end is placed. As shown in these figures, the tip of the slipper 4 has the insole 4A set under the mounting plate 5B and the grounding bottom 4B set on the mounting plate 5B. Set both of the grounding bottoms 4B on the mounting plate 5B. As described above, the holding frame 5A provided with the mounting plate 5B has a feature that the slippers can be held more reliably.

Although not shown, the moving means moves the holder 5 at the sewing position of the sewing machine 6 in the horizontal and horizontal directions along the X-axis and the Y-axis to move the peripheral edge of the bottom of the slipper 4 set in the holder 5. , Move to the sewing position of the sewing machine 6. The moving means has an X-axis drive mechanism, a Y-axis drive mechanism, and a control circuit containing a microcomputer for controlling these. The microcomputer stores the outer shape of the bottom of the slipper 4. The control circuit moves the holder 5 in the horizontal plane according to the stored data and moves the peripheral edge of the bottom to the sewing position of the sewing machine 6.

[0018]

[Effect of device]

 In the slipper manufacturing apparatus of the present invention, a holder for temporarily fixing the bottom of the slipper is provided with an elastic holding member located below the holding frame. The elastic holding member elastically presses the outside of the upper. The slipper held by the elastic holding member can prevent the bottom from being displaced during sewing. In particular, the elastic holding member holds the outside of the upper that is pushed out by the lower arm, because when the lower arm is inserted inside the upper and the upper is pushed outward, it is pushed out and can be displaced. Therefore, it is possible to effectively prevent the bottom from being displaced. Therefore, the slipper manufacturing apparatus of the present invention has the feature that the peripheral edge of the bottom can be sewn accurately and efficiently and neatly.
