Shoemaking sewing machine {SEWING MACHINE FOR SHOES}

The present invention relates to a sewing machine manufactured by sewing shoes, and in particular, by combining a feed restraining piece having a restraining tooth formed at the bottom of a support piece fixed to a support of a main body, when sewing the inner and outer skin of a shoe with a sewing needle, the transfer cup The conveying speed of the inner skin is adjusted to the conveying speed of the outer skin that is conveyed while in contact with the feed teeth to make a round that forms the toe cap of the shoe, and the conveying restraining piece is moved by the forward and backward moving means By moving forward and backward in the direction of the feed teeth formed on the transfer cup of the main body, the inner and outer skins can be pressurized and depressurized. By moving left and right at the same speed, the inner and outer skins under sewing can be moved, and then the feed sawtooth of the transfer cup can be rotated at the same speed as the transfer speed of the transfer restraint piece by the rotation means of the transfer cup, and the shifting means of the transfer restraint piece By shifting the transfer restraining piece at a speed different from that of the feed teeth of the rotating transfer cup, the inner skin can be moved at a slower feed rate than the transfer speed of the outer skin, If the speed and the speed of the inner sheath transported by the restraining teeth formed on the feed-restraining piece are kept constant, the inner and outer sheaths can be sewn in a straight line, and the speed of the outer sheath conveyed by the feed teeth is constant while the restraining teeth are fed. If the speed is reduced to cause the inner skin to slip, it is possible to make a round that forms the toe cap of the shoe, so you can get both straight and curved seams you want with one machine, improving workability and productivity. Since the lower swing piece of the rocking body is connected to the conveying body of the transfer restraint piece with the pivot pin of the pivoting body for easy movement, the conveying element can be moved forward and backward by the motion of the lower swing piece, and the conveying element is left by the pivoting pin. ,It can move to the right, and eventually the restraining teeth of the transfer restraining piece can move in the forward, backward, left, and right directions, so that two functions can be derived by using the power transmitted to one drive shaft of the sewing machine, so a very efficient operation rate. It relates to a sewing machine for shoemaking that can obtain.

In the prior art, there is a previously filed Patent Publication No. 10-2019-0062579 entitled "Gathering Sewing Machine and Method".

The above prior art, "as a sewing machine: a thread having a tightening plate and a pressing portion, the pressing portion being adjustable with respect to the tightening plate so as to allow adjustment of tension received by a thread extending between the pressing portion and the tightening plate. tensioner; a gathering assembly having a transfer cup and a transfer disk, wherein an item to be sewn can pass between the transfer cup and the transfer disc; and a transfer disc and a mechanical mechanism to variably adjust the rotational speed of the transfer disc through a friction action. It consists of "including a brake assembly that engages with the

The above prior art states that "the sewing machine is capable of gathering one or more materials through a variable speed conveying disc or conveying cup. The gathering operation can be performed to obtain different lengths of material without causing warping or other unintended deformation of the sewn article." May assist in bonding materials. Gathering operation may be used in connection with sewing an article of footwear upper with an insole portion to form a foot-receiving cavity. During the sewing operation, the tension of the thread may be adjusted. Similarly, an indication of the pressure applied to reduce the rotational speed of the transfer disk or transfer cup may be presented on the display output to ensure reproducibility across operators and articles." is the invention of

However, the above prior art is a sewing machine used to sew the inner skin and outer skin of a shoe side by side in a straight line.

In order to make a round to form a toe cap of a shoe using the above sewing machine, a high-level skill of the operator is required.

That is, while the sewing worker is constantly transported by the rotation of the transfer cup and the transfer disk, the outer skin to be sewn is left as it is, and the rear end of the endothelium immediately before sewing is pulled by hand while forcibly suppressing the transfer of the endothelium as a result of the result. got a round of

Since it is a sewing method in which the operator forcibly pulls the endothelium as described above, a desired uniform round of the front nose cannot be obtained, and since it is a manual operation, a uniform sewing line cannot be obtained.

The purpose of the present invention to solve and supplement these conventional problems,

If the speed of the outer skin transported by the feed teeth formed in the transfer cup and the speed of the inner skin transported by the restrain teeth formed on the feed restraining piece are kept constant, the inner and outer skins can be sewn in a straight line and transported by the feed teeth If the speed of the outer skin is constant and the feed speed of the restraining teeth is reduced to cause the inner skin to be pushed, it is possible to make a round that forms the toe cap of the shoe, so you can create the desired straight and curved seams in one machine. Improved workability and productivity can be improved by obtaining all of them, and since the lower swing piece of the rocking body is connected to the conveying body of the transfer restraint piece with the rotation pin of the rotating body for easy movement, the conveying body is moved forward and backward by the movement of the lower swing piece. and the conveying body can be moved left and right by the turning pin, so that the restraining teeth of the conveying restraining piece can move in the forward, backward, left, and right directions. Since two functions can be derived, it serves the purpose of obtaining a very efficient operation rate.

In order to achieve the above object, the present invention,

The bottom of the support piece fixed to the support of the main body is coupled with the transfer restraint piece with the restraining teeth formed, so that the inner and outer leather of the shoe are in contact with the transfer teeth of the transfer cup when sewing with a sewing needle. By adjusting the feed speed, it is possible to make a round that forms the toe cap of the shoe, and the feed-restrictor piece is moved forward and backward in the direction of the feed tooth formed on the feed cup of the main body by the forward and backward moving means of the feed-restrictor piece. The inner and outer skins can be blotted and depressurized, and the conveying restraining piece is moved left and right at the same speed as the rotating feed saw of the transfer cup by the left and right moving means of the transfer restraining piece to move the inner and outer covering during sewing. Then, by the rotation means of the transfer cup, the feed sawtooth of the transfer cup can be rotated at the same speed as the transfer speed of the transfer restraint piece, and by the shifting means of the transfer restraint piece, the transfer restraint piece is rotated differently from the feed sawtooth of the transfer cup being rotated. The object of the present invention can be achieved if the endothelium can be moved at a lower feed rate than the feed rate of the outer skin by variable speed movement.

Thus, the present invention can sew the inner and outer skins in a straight line by keeping the speed of the outer skin transported by the feed teeth formed in the transfer cup and the speed of the inner skin transported by the restraining teeth formed on the transfer restraint piece constant to each other. If the transfer speed of the restraining teeth is reduced while the speed of the outer skin conveyed by the feed teeth is constant, causing the inner skin to slip, it is possible to make a round that forms the toe cap of the shoe, so in one machine It is possible to obtain all desired straight and curved seam lines, which has the effect of increasing workability and productivity.

In the present invention thus formed, since the lower rocking piece of the rocking body is connected to the conveying body of the conveying member for easy movement with the rotation pin of the rotating body, the conveying body can be moved forward and backward by the motion of the lower swinging piece and rotated The pin can move the conveying body left and right, and eventually the restraining teeth of the conveying restraining piece can move in the forward, backward, left, and right directions. Therefore, two functions are derived by using the power transmitted to one drive shaft of the sewing machine. Because it can be done, it has the effect of obtaining a very efficient operation rate.

In addition, the upper swing piece 108 coupled to the front side of the first connection piece 111 while the first connection piece 111 coupling the rear side to the lower side of the second connection piece 112 moves forward and backward It rotates and reverses by pushing and pulling.

Since the center of the upper swing piece 108 is rotatably coupled to the support bolt 109 fixed to the main body 1, the front part of the upper swing piece 108 rotates and rotates around the support bolt 109. It rotates in reverse, and the swing body 105 connected to the lower part of the upper swing piece 108 moves forward and backward, so eventually the lower swing piece 106 formed on the lower side of the swing body 105 also rotates. , will make a later move.

In addition, the rotation pin 122 of the rotation body 121 press-fitted into the first press-in hole 107 of the lower swing body 106 is press-fitted through the through hole 4 of the support piece 3 to pass through the main body ( Since it is assembled with the assembly hole 104 of the conveying body 103 coupled to the support 2 of 1), the rotation pin 122 of the rotation body 121 by the forward and backward movement of the lower swing piece 106 and The restraining teeth 102 of the conveying member 103 and the conveying restraining piece 101 can also move forward and backward as shown in FIG.

On the other hand, Figures 3 to 5 are views for explaining the configuration and action for left and right movement of the restraining teeth of the shoe sewing machine of the present invention, coupled to the drive shaft 7 by the rotation of the drive shaft 7 of the main body 1 The second eccentric piece 172 moves forward and backward.

By the forward and backward movement of the second eccentric piece 172, the first connecting rod 171 coupling the rear side to the lower side of the second eccentric piece 172 moves forward and backward, while the first connecting rod 171 moves forward and backward. The second rocking piece 147 coupled to the front side of 171 is moved forward and backward, so that the first pivoting piece 145 forming the second rocking piece 147 is rotated and reversed.

In addition, the first rotation piece 145 rotates and reverses together with the first press-fit bar 134 while maintaining a fixed state to the first press-fit bar 134, and at the same time to the rear side of the first rotation piece 145. Since the formed first rocking piece 146 is also rotated and reversed, the first link 154 coupled to one side of the first rocking piece 146 is rotated and reversed.

In addition, the third link 153 coupling the rear side to the other side of the first link 154 by means of a connecting bolt 150 also rotates and reverses.

And, in the front part of the third link 153, the second pivoting piece is coupled with the fixing hole 151 to the lower side of the first press-in rod 134 exposed through the center of the first pivoting piece (145). By combining the first coupling hole 152 of 149 as shown in FIG. 10, power can be transmitted to the first press-fit rod 134 through their link action.

That is, the first link 154, the third link 153, and the second link 155 are connected by the link action of the first link 154, the third link 153, and the second pivoting piece 149. Power can be transmitted to the first press-fit bar 134 fixed to the fixing hole 151 of the second pivot piece 149 while the height of the connecting bolt 150 being coupled fluctuates as shown in FIGS. 6 and 7 There is.

In addition, the power transmitted to the first press-fit bar 134 is driven by the rotation tube 136 coupled to the upper side of the first press-fit bar 134 and the third swing piece 133 attached to the upper end of the first press-fit bar. While rotating in the left and right directions, the transmission piece 132 coupled to the rear side of the third rocking piece 133 is moved left and right.

In addition, the second press-in bar 129 attached to the front side of the fourth rocking piece 131 while the fourth swinging piece 131 coupling the rear side to the right side of the delivery piece 132 rotates and reverses. ) is rotated and reversed, and the seventh connecting piece 128 coupling the right side to the upper side of the second press-fit bar 129 is moved forward and backward, and the rear side to one side of the seventh connecting piece 127 is moved. The eighth connecting piece 127 being coupled is moved forward and backward.

In addition, the third press-in bar 125 fixed to the other side of the ninth connection piece 126 while the ninth connection piece 126, which has one side coupled to the front side of the eighth connection piece 127, moves forward and backward. is rotated and reversed, and at the same time, the tenth connecting piece 124 fixing the lower side and the rear side of the third press-in rod 9125 is also rotated and reversed.

In addition, as a result of left and right movement of the 11th connecting piece 123 coupled to the right side to the front side of the 10th connecting piece 124, the pivoting body 121 to which the 11th connecting piece 123 is coupled to the left side and rotation The pin 122 can be moved in the left and right directions inside the through hole 4 of the support piece 3.

Therefore, the rotation pin 122 moves the restraining teeth 102 of the transfer restraining piece 101 in the left and right directions by the lower rocking piece 106 and the eleventh connecting piece 123 as shown in FIG. It can.

In addition, the stroke for forward, backward, left, and right movement of the restraining teeth 102 as described above is shown in detail in FIG. 13 .

That is, the restraining teeth 102 advance and come into contact with the endothelial 181 before being sewn by the sewing needle 10, and immediately the restraining teeth 102 move to the right while turning the endothelium 181 to the right After moving in the direction, the restraining teeth 102 are moved to the rear side and separated from the endothelium 181, and immediately the process of moving to the first position on the left side is continuously and repeatedly performed at a high speed.

Accordingly, the restraining teeth 102 are operated at the same speed as the feeding teeth 9 of the feeding cup 8 that is rotated, and the outer shell 182 and the restraining teeth 102 are transferred by the feeding teeth 9. Since the inner sheath 181 transported by the same is transported at a uniform speed, as shown in FIG. 14, it is possible to sew the inner and outer sheaths 181 and 182 in a straight state.

On the other hand, with the action of the restraining teeth 102, the feed teeth 9 of the transfer cup 8 must also rotate, and the rotation of the feed teeth 9 reduces the rotational force of the aforementioned rotary pipe 136. will use

That is, the 12th coupling of the front side to one side of the fourth pivoting piece 135 formed on the upper side of the pivoting tube 136 by the rotation of the pivoting tube 136 coupled to the upper end of the first press-in bar 134 The connection piece 137 moves forward and backward, and the 13th connection piece 138, which has one side coupled to the upper side of the 12th connection piece 137, moves left and right while moving backwards and forwards to the other side of the 13th connection piece 138. The conventional one-way clutch housing 139 coupled to the side is rotated and reversed.

By the rotation and reverse rotation of the one-way clutch housing 139 as described above, the inner one-way clutch rotates in only one direction, and the transfer cup 8 and the transfer teeth 9 coupled thereto can be rotated in one direction. .

On the other hand, in order to make a round to form a toe cap on the shoe to be sewn by the guidance of the restraining teeth 102 and the feed teeth 9, the amount of feed of the restraining teeth 102, which is a restraining means, is reduced by the feed teeth 9 By reducing the speed of the shoe, it is possible to create a natural roundness of the toe of the shoe.

That is, when the control handle 165 shown in FIG. 3 attached to one side of the main body 1 and exposed to the outside is rotated, the control piece 164 coupled to the lower side of the control handle 165 is rotated and the main body ( The control shaft 163 coupled to 1) for easy rotation rotates, and the movement piece 162 coupled to the other side of the control shaft 163 moves forward and backward while the second connecting rod coupled to the lower part (161) is moved forward and backward.

In addition, since the protruding piece 159 coupled to the front side of the second connecting rod 161 moves forward and backward, the third pivot piece 156 forming the protruding piece 159 is the first part of the main body 1. As it rotates while being bolted to 1 fixture 6, the second link 155 coupling the front part to the second coupling hole 157 of the third pivot piece 156 is moved. .

As described above, the connection bolt 150 connecting the second link 155, the first link 154, and the third link 153 by the movement of the second link 155 is shown in FIGS. 8 and 9 As it is in a state of moving from the usual position (h) to a higher position (H), the link action of the first link 154, the third link 153 and the second pivoting piece 149 decreases As a result, the amount of rotation of the second pivoting piece 149 and the first press-fit rod 134 is reduced.

Therefore, the restraining teeth 102 of the transfer restraining piece 101 receiving the power transmitted through the first press-fit rod 134 hold the endothelium 181 while moving to the right at a smaller amount than the transfer saw teeth 9 Although it does not visually appear on the endothelium 181, the feed rate of the endothelium 181 is reduced compared to the feed rate of the outer skin 182 due to the phenomenon in which fine wrinkles are caught due to the shedding phenomenon, so eventually, in the direction of the endothelial 181 Since sewing is performed by the sewing needle 10 while being bent, it is possible to make a round to form a toe cap on the shoe as shown in FIG. 15.

In addition, by forming the direction of the restraining teeth 102 of the transfer restraining piece 101 opposite to the direction of the transfer teeth 9 of the transfer cup 8, consideration was given to ensure that the endothelium 181 is pushed back.
