AUTOMATIC HAT VISOR STITCHING MACHINE
[30] The present invention relates to the sewing device of the hat brim, and in particular, when positioning the feed tray to the initial initial position so that the insertion rod coupled to the feed tray can be accurately positioned to the initial starting position of the screw so that the sewing start point is always the same. The same starting point and uniform spacing of the sewing line sewn with the hat visor can be obtained, and the linear movement distance of the feeder can be controlled, so that the sewing can be variable in response to the hat visors of different widths. It is possible to smoothly sew in the unfolded state and minimize the frictional force in the rotating hat visor to ensure a smooth rotation of the hat visor and to guide the sewing of the hat visor to the sewing machine of the hat visor to obtain a good quality seams.
[31] The prior art is 1998 1998 patent application No. 18063 "curve teeth and sewing apparatus for sewing a round or oval hat window".
[32] The prior art is configured to sew a circular or oval hat brim by moving the moving body by the screw gradually increasing the width of the lead.
[33] However, the prior art described above was that the insertion rod coupled to the moving body was not accurately positioned at the initial starting position of the screw when the moving body was placed at the initial initial position for sewing on another hat brim after sewing.
[34] That is, since there is no device for controlling the rotation of the screw, the insertion rod of the movable body is usually located at the point where the screw is rotated more about the starting point of the screw or at the point where the screw is rotated less. Sewing start point also changed every time you sew.
[35] Therefore, all of the sewing lines to be sewn with the hat brim appeared differently and had a problem that a uniform sewing line could not be obtained.
[36] In addition, the prior art had a problem that the variable sewing is not possible in response to the hat brim having a different width because it can not control the linear moving distance of the moving body.
[37] And, the prior art of the bar is to transmit the elasticity of the coil spring to the guide bobbin, the coil spring is the elasticity given to the guide bobbin during the initial sewing of the hat visor and the degree of elasticity given to the guide bobbin during the final sewing of the hat visor Because of the different appearance of the hat brim caused by the strong elasticity at the beginning was not smooth sewing work could not be done and at the end of the weak elasticity was not able to squeeze the hat brim due to the problem that the sewing line is virtually affected by the problem There is a problem that can not expect the effect.
[38] The purpose of the present invention for solving and solving these conventional problems,
[39] When positioning the feeder to the initial initial position, the insertion rod coupled to the feeder can be precisely positioned to the initial starting position of the screw so that the sewing start point is always the same so that the same starting point and evenly spaced the sewing line sewn with the hat brim. It is possible to control the linear movement distance of the feeder, so that it is possible to change the sewing according to the hat brim with different widths, and smooth sewing is possible while the hat brim is always unfolded by the soft touch of the blotter plate. The friction force on the hat visor can be minimized to allow smooth rotation of the hat visor and guide the sewing of the hat visor to the end to provide a high quality sewing line.
[40] In order to achieve the above object, the present invention,
[41] Coupling the rotating plate protruding the sensing projection to the rotating shaft of the reduction motor, and equipped with a support plate of one side support the rotation sensor for detecting the sensing projection rotated by the rotation of the rotating plate,
[42] Coupling the sensing round bar to the rear side of the conveying table conveyed by the screw and is equipped with a support plate of the movement support sensor for detecting the movement of the sensing rod as a support plate,
[43] After the elastic member is coupled to the support shaft protruding from the fourth connecting rod, the lower end of the elastic member is supported by the support screw of the connecting piece, and the upper end is coupled with the adjustment cap coupled to the support shaft to rotate the adjustment cap. To adjust the elasticity,
[44] The pressure plate is loosely coupled to the center axis of the pressure plate to allow rotation.
[45] The guide plate connected to the first connecting rod to the second connecting rod can also be moved in the same way as the transfer table to achieve the object of the present invention.

[48] Detecting protrusion 104 protruding from the rotating plate 103,
[49] In order to detect the rotation of the sensing protrusion 104 is a configuration having a rotation sensor 123 mounted to the support plate 122 of the one side support 121.
[50] And, to control the linear movement distance of the conveying table 111 is coupled to the rear side of the conveying table 111 is a sensing rod 114 is fixed by the fixing bolt 115, and
[51] Further provided with a movement detecting sensor 124 mounted on the support plate 122 of the one side support 121 to detect the movement of the sensing rod 114.
[52] In addition, while being coupled with the feed table 111 which is transported by the rotation of the screw 105 connected to the rotary shaft 102 of the reduction motor 101 is coupled to the tack 143 for pressing the cap brim 154. A support shaft 137 protruding from the fourth connecting rod 136 to impart fine elasticity to the pressure plate 145,
[53] An elastic member 139 coupled to the support shaft 137 and supporting the lower end portion of the support screw 140 of the connection piece 142;
[54] The upper end of the elastic member 139 is coupled to the support shaft 137 is provided with a control cap 141 is fixed to the fixing screw 138.
[55] And, the pressure plate 145 is loosely coupled to the central axis 144 is coupled to the pressure plate 143 so that the self-rotation,
[56] The stopper plate 145 was further provided with a stopper 146 coupled to the pusher 143 to allow self-rotation only within a predetermined angle.
[57] In addition, the guide plate 133 connecting the second connecting rod 132 to the first connecting rod 131 connected to the transfer table 111 is transported with the transfer table 111 to guide the hat brim 154. It is.
[58] Referring to the operation of the present invention as described above is as follows.
[59] First, Figure 2 is a functional diagram for explaining the operation of the hat brim sewing device of the present invention, the hat brim 154 of Figure 9 for sewing work is inserted into the lower portion of the fourth connecting rod 136 and the tack 143. It is inserted into the back of the pressure plate (145).
[60] In addition, the cap brim 154 of the upper side of the pressure plate 145 passes through the lower portion of the guide piece 135 of the third connecting rod 134 and is positioned under the presser foot 152 of the sewing machine 151, and the upper portion is inclined. The guide plate 133 is positioned on the surface.
[61] When the hat brim 154 is completed as described above is to start the sewing by pressing the start button of the sewing machine 151, at the same time as the start of the sewing machine 151 power is also applied to the reduction motor 101, the rotating shaft 102 Rotated).
[62] That is, when the sewing needle 153 of the sewing machine 151 is lifted and starts sewing on the hat visor 154, the hat visor 154 should be transferred little by little in the direction of the deceleration motor 101 to the snail-shaped sewing line on the hat visor 154. The bar will be obtained, and the above-described operation will be described in detail.
[63] When the rotating shaft 102 rotates by the rotation of the reduction motor 101, the screw 105 arranged on one side support 121 and the other side support 125 also rotates.
[64] In addition, since the insertion rod 113 inserted into the valley of the screw 105 is transferred by the rotation of the screw 105, the transfer table 111 to which the insertion rod 113 is coupled is reduced in speed motor ( 101) is transferred to the direction.
[65] In addition, the first connecting rod 131 and the third connecting rod 134, the fourth connecting rod 134, the fourth connecting rod 136, the pressing rod 143, Both the connecting rod 132 and the guide plate 133 are gradually transferred from the solid line position of FIG. 2 to the virtual line position together with the transfer table 111.
[66] Thus, the sewing line sewn with the hat brim 154 can obtain a snail-shaped sewing line as shown in FIG.
[67] The reason why the lead width of the screw 105 is gradually increased is that the seam of the hat visor 154 is transferred from the outside of the hat visor 154 while gradually drawing a small circle.
[68] That is, the conveyance table 111 is slowed down by the width of the lead that increases as the advancing toward the reduction motor 101, the sewing speed by the sewing needle 153 is constant, but the rotation speed of the hat visor 154 is gradually Because it is faster.
[69] When the sewing of the hat brim 154 is completed by the above-described action, the sewing machine 151 and the motor 101 are stopped, and the worker removes the sewing hat brim 154 and inserts a new hat brim 154 at the same time. The 111 is returned to the initial initial position.
[70] At this time, since the insertion rod 113 is removed from the valley of the screw 105 by pressing the handle 112 coupled to the conveyer 111, push the conveyer 111 to its original position and prepare for the next operation. do.
[71] However, the question remains whether the insertion rod 113 of the transfer table 111 is correctly positioned at the initial starting point of the screw 105, in the present invention, the rotating plate 103 and the rotation detection sensor 123 By interacting with, it is possible to exactly match the initial initial position.
[72] That is, when the sensing protrusion 104 formed on the rotating plate 103 of the present invention is located in line with the rotation detecting sensor 123 of the support plate 122 as shown in Figs. Insertion rod 113 is to be always located at the initial point.
[73] In other words, the rotation detection sensor 123 does not operate while the feed table 111 is transported along the screw 105, and the rotation detecting sensor 123 works when the feed table 111 stops feeding. Will start.
[74] Therefore, when the sensing protrusion 104 of the rotating plate 103 is not located on the same line as the rotation detecting sensor 123, the sensing protrusion 104 is driven by driving the deceleration motor 101. After being positioned on the same straight line as 123, the deceleration motor 101 is stopped and the rotation sensor 123 is also stopped.
[75] As described above, since the sensing protrusion 104 of the rotating plate 103 stops in a state in which it is always located in the same line as the rotation detecting sensor 123, the insertion rod 113 of the transfer table 111 returned after the work is completed. Also, since it is always possible to start at the initial initial position, the same starting point and uniform spacing of the sewing line 155 sewn by the hat brim 154 can be obtained.
[76] In addition, in the present invention, it is possible to cope with a change in width of the hat brim 154 very efficiently.
[77] That is, the transfer bar 111 is also moved to the sensing rod bar 114 coupled to the high information bolt 115 at the rear side of the transfer table 111, the end of the sensing rod 114 When placed on a straight line as shown in Figure 4 and the movement detection sensor 124 mounted on the additional support plate 122 will stop the feed table 111.
[78] In other words, after adjusting the width of the hat brim 154 for sewing the length of the sensing rod (114) by releasing the high information bolt 115 of the transfer table 111 and tightening the high information bolt 115 is adjusted length As much as the detection round bar 114 is stopped after the transfer, the snail-shaped sewing line 155 can be smoothly obtained on the hat brim 154 having different widths.
[79] In addition, the tack plate 145 coupled to the tack 143 of the present invention is receiving the soft elasticity of the elastic member 139 as shown in Figures 6 and 8, so the brim 154 with the same elastic force from the beginning to the end of sewing Will be pressed.
[80] That is, since the elastic member 139 is to give elasticity to the blotter 143 using the lateral force, it is possible to consistently exhibit uniform elasticity.
[81] In addition, the elasticity of the elastic member 139 can be adjusted.
[82] That is, when the fixing screw 138 of the adjusting cap 141 is released, the adjusting cap 141 can be rotated. The supporting shaft can be rotated by rotating the adjusting cap 141 in one direction and then fastening the fixing screw 138. The elastic member 139 of 137 is in a loosened state, whereby a stronger elasticity is exhibited.
[83] In addition, when the adjustment cap 141 is reversely rotated in the opposite direction and the fixing screw 138 is fastened, the elastic member 139 of the support shaft 137 is wound, thereby exhibiting a weaker elasticity.
[84] Therefore, wrinkles are not generated in the hat brim 154 by the elastic adjustment of the elastic member 139 as described above, and sewing can be performed on the hat brim 154 in a always taut state, thereby obtaining a high quality sewing line.
[85] In addition, by adjusting the elasticity of the elastic member 139, the hat visor 154 having a thick or thin material may be sewn without problems.
[86] And, since the tack plate 145 of the present invention is loosely coupled to the central axis 144 of the tack body 143 is to move little by little with the visor 154 is rotated friction force to the visor 154 is rotated It can be minimized to enable a smooth rotation of the hat brim 154.
[87] The stopper 146 around the central axis 144 is a stopper 146 that serves to hold the pressure plate 145 so as not to rotate any more.
[88] On the other hand, the guide plate 133 of the present invention supports the hat visor 154 to rotate smoothly in addition to serving as a guide to the same as the transfer table 111 to support the sewing visor 154 to be sewn to the end of the quality seam Be considerate to get it.
[89] Thus, the present invention combines the rotating plate protruding the sensing projection to the rotation axis of the reduction motor, and by mounting the rotation sensing sensor for detecting the sensing projection rotated by the rotation of the rotating plate as a support plate of one side support. When placed in the initial initial position, the insertion rod coupled to the feeder can be precisely positioned to the initial starting position of the screw so that the sewing starting point can always be the same, so that the same starting point and the uniform spacing of the sewing line sewn with the hat visor It is possible to control the linear movement distance of the carriage by mounting the sensing rod to the rear side of the transfer table conveyed by the screw and by mounting a movement sensor to support the support plate on one side to detect the movement of the sensing rod. Variable sewing is possible by responding to hats of different widths. After the elastic member is coupled to the supporting shaft protruding from the fourth connecting rod, the lower end of the elastic member is supported by the supporting screw of the connecting piece, and the upper end is coupled with the adjusting cap coupled to the supporting shaft to resilient the elastic member by rotation of the adjusting cap. By allowing to control the smooth touch of the tack plate to enable smooth sewing in the state that the hat visor is always unfolded, and the tack plate is loosely coupled to the central axis of the tacker to allow the rotation of the visor to rotate to enable friction Since it is possible to minimize the smooth rotation of the hat visor and the guide plate connected to the second connecting rod to the first connecting rod can be moved in the same way as the transfer table to guide the sewing of the hat visor to the end to obtain a high quality sewing line Has a useful effect.
