The present invention relates to a stapler having a mechanism for pulling a button holding member.

Background of the invention

For example, in the third to seventh drawings, a conventional stapler structure having a mechanism for pulling up a button holding member described in Patent Document 1 will be described.

The button fastening machine includes a machine arm 21a having a needle N or the like, a machine tool 21b having a cloth lowering plate 22, and the like, and is coupled to a cam (not shown) and is slidably coupled to the cam. The feed mechanism 23 is a feed table 23 that slides on the machine tool 21b, and a button holding member 24 that is rotatably supported by the fulcrum shaft 24d. The button holding member 24 is normally pressed by the push rod 24f to the lower side by the spring 24e with the potential energy applied thereto. The structural member of the button holding member 24 is disposed opposite to the button holding portion 24a, 24b and the pressing cloth lower portion 22 at one of the outer periphery of the front end portion holding button.

As shown in Fig. 7, a snap hook 24c bent in an inverted J shape is formed on the button holding member, and the engaging hook 24c is extended by the upright portion 24c1 and the front end of the upright portion 24c1 which is folded obliquely downward. The portion (inclined extension portion) 24c2 is disposed, and the engagement hook 24c is disposed to be engageable with the upper hook 26 to be described later. Then, the button holding portions 24a and 24b are rotatably supported at a lowering position close to the pressing lower plate 22 and away from the pressing lower plate 22 around the base portion 24d, so that the button holding portions 24a and 24b sandwich the button. Rising position Set.

Further, in order to cooperate with the rotation of the push-up hook 26 with the rotation of the push-up lever 25, the push-up hook 26 is most efficiently and surely engaged and slid, and the engaging hook 24c is designed to be extended. The imaginary extension line of the portion (inclined extension portion) 24c2 points in the direction of the center of the rotation of the upper push rod 25.

The shaft 27 is rotatably supported by the intermediate portion at the intermediate portion of the arm 21a. The push rod 25 is formed in the groove portion of the rotary link 28 which is rotatably supported by the arm 21a on the shaft 28a. The shaft body 25a is coupled to the upper end of the actuating wrist 51 and the upper end of the link 33, which will be described later, to the same shaft. A slightly L-shaped upper pushing member 26 is formed at an end portion of the upper push rod 25, and the pushing member 26 is perpendicularly intersected from the front end of the hanging portion 26a and the longitudinal direction of the pressing rod 25 from the front end of the hanging portion 26a. The direction extends and is formed by an extending portion 26b perpendicularly intersecting the extending portion 24c2 of the engaging hook 24c.

When the actuating wrist 51 is lowered, the upper push rod 25 is rotated about the shaft 27, and the extending portion 26b of the push-up member 26 of the upper push rod 25 is followed by the extension of the aforementioned engaging hook 24c provided to the button holding member 24. When the 24c2 is engaged, the button holding portions 24a and 24b are lifted upward and moved upward from the pressing plate 22.

Returning to Fig. 3, the buttoning machine has a tangential 29 knife located below the needle plate 21c, and the tangential cutter 29 is coupled to the actuating wrist 51 by the links 30, 31, 32, 33 interlocking with the actuating wrist 51. When the actuating wrist 51 is lowered, the thread cutting blade 29 is horizontally moved with the rotation of the upper push rod 25, and the line connecting the wire hook is cut from the cloth between the fixed blades outside the drawing. Further, the tangential cutter 29 and the links 30 to 33 constitute a tangential mechanism.

The main body shaft 34 supported by the machine tool 21b is represented by the clutch shown in FIG. The mechanism 35 transmits the rotational force from a drive source (not shown) of the button motor or the like. In other words, the clutch mechanism 35 includes a blocking slip 35a having a truncated cone-shaped braking portion 35a1 fixed to the main body main shaft 34, and a driving pulley 35b that is rotatable relative to the main shaft 34 of the machine body and moved in the axial direction. The 35b forms a concave surface portion 35b1 that is insertable and detachable with respect to the aforementioned braking portion 35a1. Further, the drive pulley 35b is coupled to a drive source outside the drawing by a belt 35c that is stretched over the outer peripheral surface thereof, and the brake portion 35a1 is fitted to the drive pulley 35b by the concave surface portion 35b1, whereby the rotational force of the motor can be transmitted to Body spindle 34.

As shown in Figs. 3 to 5, the outer peripheral surface of the eccentric cam 36 fixed to the main body main shaft 34 contacts one of the pair of sliding portions 37a and 37b of the double-fork-shaped rocking link 37. The eccentric cam 36 is rotated once with the main body main shaft 34, and the rocking link 37 is rocked back and forth about the shaft 38, and the locking portion 37c formed at one end thereof is moved up and down.

The drive control shaft 39, which is disposed in parallel with the main body main shaft 34, is interlocked with the main body main shaft 34 by the interlocking mechanism, and is rotated once by the sewing machine main shaft 34 by the sewing cycle amount. The first control cams 40 fixed to the drive control shaft 39 form first recesses (first actuation portions) 40a and 40b at intervals of 180 Å on the outer peripheral surface thereof. The recesses 40a and 40b are formed at a rotation angle range of one stitch of the control cam 39 (a range of rotation angles of the drive control shaft 39 corresponding to one rotation of the main body main shaft 34). For example, it is formed in an angular range of 1.5 stitches. Similarly, the second recesses (second actuation portions) 41a and 41b are formed at an outer peripheral portion of the second control cam 41 fixed to the drive control shaft 39 at an angular interval of 180 。.

A rotary rocking shaft 43 that is rotatably supported by the machine tool 21b and has a hollow shape is disposed in parallel with the aforementioned drive control shaft 39. Then, rotate freely The first rotary rocking shaft 42 that is inserted into the hollow portion of the second rotary rocking shaft 43 forms a double shaft structure together with the second rotary rocking shaft 43 (see FIG. 4).

Therefore, the rising position at the end of the pulling of the button holding member 24 is generally in a state related to the engagement position of the extending portion 24c2 and the circumferential surface of the upper push hook 26.

Therefore, the shock (vibration) generated when the main shaft 34 of the main body is disconnected from the drive source is blocked, and once the engagement of the push hook 26 and the engagement hook 24c is released, the engagement position is changed when the oscillation subsides. Before the jump, the button holding member 24 cannot be supported at a predetermined upper and lower position, which causes a disadvantage that the operator does not easily place the button on the button holding portions 24a, 24b.

Further, since the extending portion 24c2 engaged with the circumferential surface of the push-up hook 26 is formed to be inclined in the direction of the arrow f, when the button holding member 24 is in the raised position, the weight of the button holding member 24 applied to the extending portion 24c2 is The button holding member 24 generates the imparting ability of the feeding direction (arrow direction f), and the imparting force is transmitted to the feeding mechanism (not shown) by being coupled to the base portion 24d of the feeding table 23, and the feeding mechanism is also formed. The main cause of the disadvantages such as incorrect fitting of the feed cam and the engaging member engaged with the feed cam at the start of sewing.

Therefore, the object of the present invention is to provide a button holding member that can be supported at a predetermined position under the influence of vibration (vibration) generated when the main shaft of the body is not connected to the driving source, so that the operator can clamp the button. The button of the holding part is placed in a simple buttoning machine.

Further, it is an object of the present invention to provide a button fastening machine which can prevent the occurrence of the imparting ability of the button holding member 24 in the feeding direction when the button holding member 24 is in the raised position, and remove the main cause of the disadvantage of the feeding mechanism. .

In order to achieve the above object, the button fastening machine of claim 1 includes a middle portion that is rotatably supported on the upper arm of the arm; and a button holding portion that holds the button at the front end portion, and a button holding member that is rotatably supported by the machine tool to move the button holding portion up and down; a snap hook that protrudes upward from the button holding member and has an extending portion extending in the lateral direction; and The front end portion of the upper push rod protrudes downward and has a hook on the extension portion opposite to the extension portion of the engaging hook. Also, by the aforementioned push rod in one direction Rotating, the extending portion of the push-up hook is engaged with the extending portion of the engaging hook, and the button holding member is pulled upward. The front end surface of one of the push-up hook and the engaging hook is disposed to engage with a surface of the extension portion of the other in the extending direction.

Further, another feature is that one of the aforementioned front end faces is formed in a plane to be in contact with the face of the other extension portion.

According to the button fastening machine of the present invention, the peripheral surface of the extending portion of the one of the push-up hook and the engaging hook that is engaged with the button holding member when the button holding member is moved to the raised position abuts against the front end surface of the extension portion of the other, and supports The button holding portion.

Therefore, it is possible to suppress the occurrence of a load acting on the opening end direction of the engaging hook when the pulling of the button holding member is completed. Therefore, even when the main shaft of the body is disconnected from the driving source, vibration is generated, and the hook is pushed up. The engagement position of the snap hook does not change before and after the jump, and the button holding member can be normally supported at a predetermined position. Therefore, it is also convenient for the operator to place the button on the button holding portion.

In particular, when the front end surface is formed to move the button holding member to the raised position, the upper push hook and the engagement hook can be smoothly engaged (slidably) on the plane extending in the horizontal direction, and the button holding member can be made. The support is true.

Further, when the button holding member is in the raised position, the generation of the ability to impart force to the button holding member in the feeding direction can be prevented, and the main cause of the disadvantage of the feeding mechanism can be removed.
