In addition, the vertical guide bar 17 of the vertical feed mechanism 11a is installed on the upper surface of the horizontal movement table 23, thereby integrating the horizontal movement of the center table 2a and the side table 2b. .
[0019]
By providing such a table drive mechanism 11 (vertical feed mechanism 11a and lateral feed mechanism 11b), the dough table 2 has an external position where the superposed dough 5 is placed on and taken out of the table, and the superposition on this table. The cloth 5 can be put in and out (vertical feed drive) between the cloth 5 and the position where it is put out to the sewing machine 4 with a button. Further, at the position where the buttoned sewing machine 4 is inserted, a feeding operation is performed in which each buttonhole 6 is replaced with the needle position of the buttoned sewing machine 4 in accordance with the hole pitch of the buttonhole 6 provided in the buttoned cloth 5a of the polymerized cloth 5. (Transverse drive) is possible.
[0020]
The sewing preparation means 3 is for holding the button hole 6 in the cloth 5a with a button hole among the superposed cloths 5 supported on the cloth table 2, and is provided on the button sewing machine 4 side. .
As shown in FIGS. 6 and 7, the sewing preparation means 3 has a pair of opening / closing operation tools 26 and 27. The opening / closing operation tools 26 and 27 are provided with claws 26a and 27a that protrude downward in a bent shape from the tip portions facing each other. The claws 26a, 27a of the opening / closing operation tools 26, 27 can be engaged with the button holes 6 of the cloth 5a with button holes, respectively.
[0021]
The opening / closing operation tools 26 and 27 can be opened and closed by the opening / closing mechanism 28 so that the claws 26a and 27a are brought close to and away from each other.
The opening / closing mechanism 28 includes a slide bar 31 that supports one opening / closing operation tool 26 via an L-shaped bracket 30, a slide bar 33 that supports the other opening / closing operation tool 27 via an L-shaped bracket 32, and both A bearing 34 that holds the slide bars 31 and 33 parallel to each other and movably horizontally, an extrusion driving tool 35 that can press the base end of one slide bar 33, and the relative relationship between the slide bars 31 and 33. And an interlocking mechanism 36 that interlocks reverse movement.
[0022]
The extrusion driving tool 35 is composed of a fluid pressure cylinder, a solenoid or the like. The push driving tool 35 is not connected to the slide bar 33. Therefore, the driving force is transmitted to the slide bar 33 only when the push driving tool 35 is operated in the push direction.
The interlocking mechanism 36 is interlocked attached to each base end portion of the slide bars 31 and 33 by a reversing drive lever 38 that is swingable about a pivot 37 provided between the slide bars 31 and 33. In this structure, the projections 40 and 41 are engaged and pushed or pulled.
[0023]
That is, when the slide bar 33 is driven to be pushed out by the operation of the push-out driving tool 35 (when moving in the right direction in FIG. 7), the interlocking protrusion 41 of the slide bar 33 is connected to one end (upper end) of the reverse drive lever 38. ) Is rotated, the reversal drive lever 38 is pivoted about the pivot 37 (rotation in the clockwise direction in FIG. 7), and the other end portion (lower end portion) of the reversal drive lever 38 is accordingly accompanied. ) Pulls the interlocking protrusion 40 of the other slide bar 31 in the direction opposite to the slide bar 33 (to the left in FIG. 7).
[0024]
Thus, in this interlocking mechanism 36, both opening / closing operation tools 26 and 27 can be driven in opposite directions only by the operation of the extrusion driving tool 35.
The slide bars 31 and 33 are provided with slide shoes 42 and 43, respectively, which serve as guides for the other party bar. Among these, the slide shoes 42 and the bearing 34 of the slide bar 31 (the slide bar 31) are provided. A return spring 44 is inserted between the 33 slide shoes 43 and the bearings 34).
[0025]
The return spring 44 enables the return operation of the slide bars 31 and 33 after the operation of the push-out driving tool 35 is stopped and returned.
Such an opening / closing mechanism 28 is provided with respect to the mounting substrate 45, and this mounting substrate 45 is held by the shaft support portion 47 via the horizontal pivot 46 and is attached to the button via this shaft support portion 47. It can be attached to the sewing machine 4 or the like.
Accordingly, the opening / closing mechanism 28 can move up and down as the mounting substrate 45 swings up and down around the horizontal pivot 46.
[0026]
The mounting board 45 is provided with a tail 48 extending from the mounting position of the horizontal pivot 46 to the side opposite to the side where the opening / closing operation tools 26 and 27 are provided (left side in FIG. 7). The shaft support portion 47 is provided with a bracket 49 extending in the same direction as the tail portion 48 of the mounting substrate 45.
The tail portion 48 of the mounting substrate 45 and the bracket 49 are connected by a spring 50. In addition, between the tail portion 48 of the mounting substrate 45 and the bracket 49, an expansion / contraction operation tool 51 including a fluid pressure cylinder, a solenoid, and the like is provided on one side (the bracket 49 side in the illustrated example). In the example shown in the figure, a tailing piece 52 is provided on the tail portion 48) of the mounting substrate 45 in order to receive the extension operation by the telescopic operation tool 51 (to cause a reaction).
[0027]
Accordingly, when the telescopic operation tool 51 is actuated, the attachment substrate 45 is swung as a reaction, and the opening / closing operation tools 26 and 27 are lifted. When moving toward the attachment sewing machine 4, the opening / closing operation tools 26, 27 become an obstacle to the superposed fabric 5 held on the fabric table 2 by operating the telescopic operation tool 51 in advance. This (causes contact interference) can be avoided.
The button-attached sewing machine 4 is conventionally known, and when the cloth (referred to as a button-unclothed cloth 5b of the polymerized cloth 5 in the present invention) and the button 7 are respectively supplied in a predetermined arrangement to the needle position, 7 (see FIG. 1) can be attached to the fabric by sewing, aiming at a plurality of sewing holes 55.
[0028]
Next, the button attachment method according to the present invention will be described based on the procedure for attaching the button 7 to the polymer fabric 5 using the button attachment device 1 having the above-described configuration.
First, as shown in FIG. 2, the polymerized fabric 5 is placed on the fabric table 2 in a state where the fabric table 2 is positioned at an outer position in front of the buttoned sewing machine 4. This may be a manual operation by an operator.
At this time, it is assumed that the superposed fabric 5 is stacked so that the fabric 5a with a button hole is on the top and the unattached fabric 5b is on the bottom, and is held in the predetermined positional relationship described above.
[0029]
Further, on the upper surface of the fabric table 2, for example, a laser marker (not shown in the figure, but a guide for positioning one button hole 6 or the like in the fabric 5a with a button hole) It is preferable to apply a mark irradiated with a mark to be performed.
In the sewing preparation means 3 provided on the button sewing machine 4 side, the telescopic operation tool 51 performs an extension operation and stands by in a state where the opening / closing operation tools 26 and 27 are lifted.
When the superposition | polymerization dough 5 has been positioned with respect to the dough table 2, the hook 14 of the dough grasping mechanism 10 is lowered and presses the superposition dough 5 onto the dough table 2 by manual switch operation or an automatic system based on a sensor detection signal. Then, the substantial operation of the button mounting device 1 is started.
[0030]
That is, as shown in FIG. 8, the lateral feed mechanism 11b of the table drive mechanism 11 (see FIG. 5) is operated to move the entire fabric table 2 left and right, and the button-holed fabric 5a of the polymer fabric 5 on the table is moved. The button hole 6 is aligned with the front position with respect to the needle position of the button sewing machine 4.
Further, the vertical feed mechanism 11a is operated to move only the side tables 2b on both sides of the dough table 2 toward the buttoned sewing machine 4, and the button holes 6 of the dough 5a with button holes in the superposed cloth 5 on the table are moved to the buttoned sewing machine. Align just below the 4th needle position.
[0031]
The operation order of the vertical feed mechanism 11a and the horizontal feed mechanism 11b may be either first or in some cases.
Next, the expansion / contraction operation tool 51 of the sewing preparation means 3 (see FIGS. 6 and 7) stops the extension operation and returns to the state before the extension, and the opening / closing operation tools 26 and 27 are moved by the contraction force of the spring 50. The nail | claw 26a, 27a is made into the state contact | abutted on the fabric upper surface of the fabric 5a with a button hole.
The vertical feed mechanism 11a of the table drive mechanism 11 performs a forward / reverse switching drive within a predetermined range so that the open / close operation tools 26 and 27 are reciprocated.
[0032]
Accordingly, the claws 26a, 27a of both the opening / closing operation tools 26, 27 are horizontally reciprocated so as to move back and forth on the button hole 6 while being in contact with the upper surface of the cloth 5a with the button hole (about 2 to 3 reciprocations). Therefore, the claws 26a and 27a are surely engaged with the button hole 6 during the reciprocation.
Therefore, the push-out driving tool 35 of the opening / closing mechanism 28 (see FIGS. 6 and 7) in the sewing preparation means 3 is operated to move the opening / closing operation tools 26 and 27 (the claws 26a and 27a) in the direction away from each other. .
[0033]
Thereby, as shown in FIG. 1, the button hole 6 of the cloth 5a with a button hole is made into an open state, and this state is maintained. Accordingly, the button attachment planned position (position indicated by x in FIG. 4) in the button unattached cloth 5b is exposed in the button hole 6.
Note that the button-equipped sewing machine 4 has already been supplied with one button 7 toward the needle position at this point. That is, the button 7 in the supplied state stands by just above the button hole 6 held open.
[0034]
Therefore, in this button sewing machine 4, the button 7 is placed on the button hole 6 in the open state, and a plurality of sewing holes 55 provided in the button 7 are formed through the button hole 6. Aiming is attached to the unbuttoned fabric 5b by sewing.
After the sewing is finished, the push-out driving tool 35 of the opening / closing mechanism 28 stops and returns to operation, and the opening of the button hole 6 by the opening / closing operation tools 26 and 27 is stopped (that is, the button hole 6 is closed). ). Then, the telescopic operation tool 51 performs an extension operation to bring the open / close operation tools 26 and 27 into a lifted state.
[0035]
At this stage, it is clear that the button 7 is fitted in the button hole 6.
Thereafter, as shown in FIG. 9, the above operation is repeated for the number of button holes 6 provided in the cloth 5a with button holes. When the buttons 7 are fitted in all the button holes 6, the dough table 2 moves away from the button sewing machine 4 and returns to the front front position as shown in FIG.
Therefore, the one-cycle operation of the button mounting device 1 according to the present invention is completed by taking out the polymerized fabric 5 from the fabric table 2.
[0036]
By the way, the present invention is not limited to the above-described embodiment, and can be appropriately changed according to the embodiment.
[0037]
【The invention's effect】
