MODE FOR CARRYING OUT THE INVENTION

[0066] The present invention relates to a method for manufacturing non-slip socks, which fits a sock main body 1 to a mold, arranges a gripping member 2 on a surface of the sock main body 1, and then presses and bonds the gripping member 2 to the surface of the sock main body 1 by using a press.

[0067] FIG. 2 is a photograph showing a state in which the gripping member 2 is bonded to a fabric 3.

[0068] The gripping member 2 may be made of various materials for exhibiting a non-slip function. Preferably, the gripping member 2 may be made of a wet-type polyurethane sheet.

[0069] The wet-type polyurethane sheet is disclosed in the patent document 4 and illustrated in FIGS. 2 and 3.

[0070] Specifically, a gripping surface may be formed: by manufacturing the wet-type polyurethane sheet by using one of the fabric 3 or a polyester film as a carrier and then removing the carrier to obtain a surface from which the carrier is removed and use the surface as the gripping surface; by impregnating and coating a non-woven fabric with a polyurethane resin in a process of manufacturing the wet-type polyurethane sheet and then removing a surface skin of sheet manufactured after performing a process for solidifying and removing DMF to obtain a surface from which the surface skin is removed and use the surface as the gripping surface; or by manufacturing the wet-type polyurethane sheet by using one of the fabric 3 or the polyester film as a carrier and then removing a surface layer at an opposite surface of the carrier by using a sandpaper to use the surface as the gripping surface.

[0071] The polyurethane sheet manufactured by the above method has a structure, in which numerous pores are formed therein, external moisture is introducible to a space around the frame, and all or a portion of the introduced moisture is dischargeable to a bottom surface or a wall surface, and form a gripping surface by forming a micro-uneven surface through the above method such as carrier removal, surface skin removal, or sandpaper removal.

[0072] The gripping member 2 in FIG. 3 has a structure in which a column cell 2b having a roly-poly toy shape is formed therein.

[0073] In addition, the gripping member 2 has a structure in which a non-slip groove 2c communicating with the column cell 2b is formed as a portion of the column cell 2b is torn when the carrier such as the fabric 3 is detached.

[0074] A feature of forming the gripping member 2 having a predetermined pattern on the fabric 3 may be performed by using a roll cutter.

[0075] In addition, a hot-melt adhesive 2a is applied to the exposed surface of the gripping member 2 so that bonding using a heat press is easily performed and bonded to the sock main body 1 when pressure and heat is transferred through the heat press.

[0076] In addition, in a finishing process of the roll cutter, the fabric is cut into a predetermined gap to have a rectangular shape as in FIG. 2.

[0077] Referring to FIG. 2, three or four gripping members are repeated in a direction from a left side to a right side on the picture.

[0078] In this case, as schematically illustrated in FIG. 3, the fabric 3 cut in the roll cutter is manufactured such that the fabric in which four gripping members are disposed on an end thereof and the fabric in which three gripping members are disposed on an end thereof are continuously and alternately manufactured.

[0079] In this case, when the fabric in which four gripping members are disposed on the end thereof is arranged and bonded to an inside of the sock, the in which three gripping members are disposed on the end thereof is arranged and bonded to an outside of the sock.

[0080] Since a bonding state between the fabric 3 and the gripping member 2 is easily broken when a person holds and tears by hands, when the fabric 3 is pulled by hands in a state in which the gripping member 2 is bonded to the sock main body 1 through the hot-melt adhesive and the press, the gripping member 2 and the fabric 3 are easily detached from each other.

[0081] Hereinafter, an apparatus for manufacturing non-slip socks of the present invention, which manufactures non-slip socks by bonding the gripping member on the fabric to the socks will be described.

[0082] 1. Inside Setting Process

[0083] As illustrated in FIG. 4, a mold 40 in which a fabric guide groove 43a in which the fabric 3 with the gripping member 2 bonded is seated is prepared.

[0084] Thereafter, as illustrated in FIG. 5, the fabric 3 is seated in the fabric guide groove 43a, and the gripping member 2 faces upward.

[0085] 2. Sock Installation Process

[0086] As illustrated in FIG. 6, the sock main body 1 is fitted to the mold 40 on which the fabric 3 is seated, so that the inner circumferential surface of the sock main body 1 faces the gripping member 2.

[0087] 3. Inside Press Process

[0088] As illustrated in FIG. 7, an one side press device 51 including a lower mold 50a for supporting a lower portion of the mold 40, an upper mold 50b spaced upward from the lower mold 50a, a heating wire installed on one of the lower mold 50a and the upper mold 50a, and an actuator connected to one of the lower mold 50a and the upper mold 50a is prepared, and then the gripping member 2 inside the sock main body 1 is bonded to the inside of the sock main body 1 such that one side of the mold 40 is disposed between the lower mold 50a and the upper mold 50b, and then the upper mold 50b moves downward to heat and press the sock main body 1.

[0089] Although an example in which the actuator is connected to the upper mold 50b, and the heating wire is attached to the inside of the upper mold 50b is illustrated in the drawing, as the actuator and the heating wire may be connected to the lower mold 50a, the two molds may be simultaneously operated from the top and the bottom.

[0090] More preferably, the one side press device 51 includes a first one side press device 51a and a second one side press device 51b, which are spaced apart from each other, and the inside press process is performed such that the gripping member 2 and an inner circumferential surface of the sock main body 1 is firstly temporarily bonded in the first one side press device 51a, a cooling time elapses while the mold 40 moves to the second one side press device 51b, and then the gripping member 2 and the inner circumferential surface of the sock main body 1 is secondarily completely bonded in the second one side press device 51b.

[0091] 4. Outside Setting Process

[0092] As illustrated in FIG. 8, a guide device 60 including a movable frame 61 moving vertically toward the mold 40 is prepared, wherein a fabric guide member 62, in which a guide hole 62a for guiding an arrangement position of the fabric 3 on the sock main body 1 fitted to the mold 40 is formed, is installed on the movable frame 61. Thereafter, the fabric guide member 62 is disposed above the sock main body 1, and the separate fabric 3 with the gripping member 2 bonded is inputted to the guide hole 62a, so that the gripping member 2 is disposed below the fabric 3.

[0093] Alternatively, a mark caused by the pressing may be generated in a surface because the sock main body 1 firstly receives heat and pressure through the inside press process, and this pressing mark may be used as a guide so that the gripping member 2 is disposed below the fabric 3.

[0094] In this case, however, since the fabric 3 is positioned by a manual work, accuracy may decrease, and the position may be changed by static electricity and wind, it will be much better to use the guide device 60.

[0095] 5. Outside Press Process

[0096] The other side press device 52 including a lower mold 50a supporting a lower portion of the mold 40 and an upper mold 50b spaced upward from the lower mold 50a, including a heating wire 50c installed therein, and connected with the actuator to vertically move is prepared. Thereafter, one side of the mold 40 is positioned between the lower mold 50a and the upper mold 50b, and then the upper mold 50b moves downward to heat and press the gripping member disposed on the sock main body 1 so that the gripping member 2 is bonded to an outer surface of the sock main body 1.

[0097] A configuration and a press state of the the other side press device 52 may be substantially the same as those of FIG. 7.

[0098] More preferably, the the other side press device 52 may include a first the other side press device 52a and a second the other side press device 51b, which are spaced apart from each other, and the outside press process may be performed such that the gripping member 2 and an outer circumferential surface of the sock main body 1 are firstly temporarily bonded in the first the other side press device 52a, the fabric 3 disposed on the outer circumferential surface of the sock main body 1 is separated from the gripping member 2, and then the gripping member 2 and the outer circumferential surface of the sock main body 1 are secondarily completely bonded in the second the other side press device 52b.

[0099] FIGS. 9 and 10 illustrate the manufacturing apparatus for achieving the above-described configuration.

[0100] The manufacturing apparatus includes a support frame 10, a rotation table 20, a mold connection member 30, a mold 40, a press device 50, and a guide device 60.

[0101] As illustrated in FIGS. 9 and 10, the support frame 10 includes an upper plate having a circular shape, and a circular guide groove 11 in which the rotation table 20 is seated is formed in the upper table.

[0102] In addition, a driving motor 12 is installed at one side of a lower portion of the support frame 10.

[0103] The rotation table 20 has one side connected with the driving motor 12 and an upper portion seated in the guide groove 11 and rotates along the guide groove 11 by an operation of the driving motor.

[0104] Although an arrangement state between the rotation table 20 and the driving motor 12 in the drawing is simply illustrated for easy understanding, a structure and a connection relationship between the rotation table 20 and the driving motor 12 may be configured by various well-known structures allowing the rotation table 20 to rotate.

[0105] For example, a method of forming gear teeth in an inner circumferential surface of the rotation table 20, arranging a circular gear engaged with the gear teeth in an upper or lower portion of the support frame 10, and connecting the driving motor 12 to the gear may be used.

[0106] As illustrated in FIGS. 9 and 10, the mold connection member 30 having one side connected to the rotation table 20 to rotate together with the rotation table 20.

[0107] The mold connection member 30 has the other side protruding in an outward direction of the rotation table 20, and a plurality of mold connection members 30 are arranged radially around a center of the rotation table 20.

[0108] In the drawing, the other side of the mold connection member 30 includes two frames disposed in parallel so that two molds 40 are mounted thereto. Since socks typically include a pair of socks (two socks for left and right feet), the two frames are provided so that one pair of socks are manufactured at once.

[0109] As illustrated in FIG. 9, the mold 40 has one side connected with the mold connection member 30 and an upper portion in which a fabric guide groove 43a in which the fabric 3 with the gripping member 2 bonded is seated is formed, so that the sock main body 1 is fit to the mold 40.

[0110] In case that the fabric guide groove 43a is formed in the mold 40, the mold 40 arranges the fabric 3 to which the plurality of gripping members 2 are bonded at an exact position when the gripping member 2 is bonded to the inside of the sock to increase a bonding position accuracy of the gripping member 2.

[0111] However, when a numeric value of a sum of a height of the fabric 3 and a height of the gripping member 2 is less than that of a depth of the fabric guide groove 43a, the gripping member 2 may not be bonded to the sock main body 1 through the press.

[0112] Furthermore, in case that the fabric guide groove 43a has a low depth, a phenomenon in which the fabric 3 is bonded to an inner circumferential surface of the sock when the sock is fitted to the mold 40 to move a position that is not a bonding target position is generated.

[0113] To restrict the above-described phenomenon, the mold 40 may include a connection plate 41, a seat member 42, and an elevation member 43 as illustrated in FIG. 11.

[0114] The connection plate 41 has an overall shape and a size, which correspond to an approximately foot shape so that the socks fit tight.

[0115] The seat member 42 may be installed on the connection plate 41, and the fabric 3 with gripping member 2 bonded is seated on the seat member 42.

[0116] Also, the elevation member 43 is configured such that the fabric guide groove 43a through which the seat member 42 passes is defined therein, and a lower portion thereof is connected to the connection plate 41 through an elastic member 44 to vertically move by an upper pressure.

[0117] Here, the elastic member 44 may be made of flexible foam such as a sponge. The elastic member 44 may be made of a material that is preferably resistant to heat and has a restoration force that is not weakened when a pressure is applied.

[0118] In order to prepare a case in which the restoration force of the elastic member 44 is reduced by receiving a repeated compressive force or by a thermal damage, a plate spring 45 having both rounded ends and made of a metal material may be further installed between the connection plate 41 and the elevation member 43 as illustrated in the drawing.

[0119] In case that the mold 40 is configured as described above, since the fabric guide groove 43a may have a great depth, the fabric 3 may be restricted from being separated from the fabric guide groove 43a due to a friction of the inner circumferential surface of the sock main body 1 when the socks are fitted to the mold 40 after the fabric 3 is inserted to the fabric guide groove 43a.

[0120] Also, when a pressing operation is performed, a height of the elevation member 43 may be lowered, and thus the press may easily compress the gripping member 2.

[0121] Here, when a thickness of the gripping member 2 is varied according to the kind of the socks, or the elevation member 43 is not easily restored due to a damage of the elastic member 44, a height of the seat member 44 may be lowered to be simply and continuously used.

[0122] That is, the seat member 42 may adjust a height from the connection plate 41.

[0123] More specifically, as illustrated in FIG. 12, a through-hole 41a that is vertically perforated is formed to form the fabric guide groove 43a in the elevation member 43, and a stepped portion 41b obtained by bending a middle portion of an inner wall of the through hole 41a in an outward horizontal direction is formed.

[0124] Here, the seat member 42 may be configured to adjust a height of a bottom thereof such that the seat member 42 has an upper portion inserted to the through-hole 41a and a lower portion forming a protruding portion 42a protruding in the outward horizontal direction, and an adjusting bolt 42b screw-coupled to the stepped portion 41b is formed to pass through the protruding portion 42a.

[0125] Also, as illustrated in FIG. 12, in order to further restrict the phenomenon in which the fabric 3 is bonded to the sock main body 1 due to friction or an electrostatic phenomenon, a suction hole 46 may be formed on the seat member 42, and a suction pump 46a connected to the suction hole 46 through a hose or the like may be provided.

[0126] In case that the suction pump 46a is operated when the socks are fitted to the mold 40 after the suction pump 46a is installed, and the fabric 3 is inserted to the fabric guide groove 43a, a phenomenon in which the fabric 3 is suctioned to the sock main body 1 by an air suction force may be further restricted.

[0127] Also, when the suction pump 46a is turned on and off in a short frequency after the pressing operation is finished, the fabric 3 may be easily detached from the gripping member 2, and when the suction pump 46a is operated in a state in which the fabric 3 is placed by using the guide device 60 to bond the gripping member 2 to an outside of the sock main body 1, and the rotation table 20 rotates toward a next press device, the fabric 3 disposed on the sock main body 1 may not be easily separated from the sock main body 1.

[0128] To this end, a plurality of suction holes 46 may be defined although only one suction hole 46 is illustrated in the drawing.

[0129] The press device 50 includes a typical heat press and is installed adjacent to one side of the support frame 10. Specifically, the press device 50 includes: a lower mold 50a for supporting a lower portion of the mold 40; and an upper mold 50b spaced upward from the lower mold 50a, including a heating wire 50c installed therein, and connected with an actuator 50d to vertically move and press an upper portion of the mold 40, thereby heating and pressing the sock main body 1 fitted to the mold 40, so that the gripping member 2 is bonded to the sock main body 1.

[0130] More specifically, the press device 50 includes one side press device 51 for heating and pressing to bond the gripping member 2 to the inside of the sock main body 1 and the the other side press device 52 for heating and pressing to bond the gripping member 2 to the outside of the sock main body 1.

[0131] The two press devices are disposed as illustrated in FIGS. 9 and 10. That is, the one side press device 51 is disposed in one side direction along a circumference of the support frame 10 with respect to the guide device 60 to heat and press the fabric 3 disposed between the sock main body 1 and the mold 40.

[0132] The the other side press device 52 is disposed in the other side direction along the circumference of the support frame 10 with respect to the guide device 60 to heat and press the fabric 3 disposed outside the sock main body 1 fitted to the mold 40

[0133] Here, in case that the sock main body 1 has a small thickness or is easily damaged by heat, a phenomenon in which the sock main body 1 is damaged is generated when heated and pressed for a long time at once.

[0134] In order to prevent this phenomenon, the one side press device 51 may include a first one side press device 51a and a second one side press device 51b, and the the other side press device 52 may include a first the other side press device 52a and a second the other side press device 52b as illustrated in the drawing.

[0135] In a plan view of FIG. 10, since the first one side press device 51a and the second one side press device 51b are spaced a predetermined angle from each other with respect to a center of the support frame 10, the sock main body 1 is cooled while the mold 40 moves from the first one side press device 51a to the second one side press device 51b.

[0136] The first the other side press device 52a and the second the other side press device 51b of the the other side press device 52 have a predetermined angle therebetween as illustrated in the drawing, the angle therebetween is two times greater than that between the first one side press device 51a and the second one side press device 51b with respect to the center of the support frame 10.

[0137] Since the first the other side press device 52a heats and presses the gripping member 2 through the fabric 3 instead of directly heating and pressing the gripping member 2, the first the other side press device 52a has a long heating time and a higher heating temperature than the one side press device 51. In this case, since the sock main body 1 may be damaged, the fabric 3 is separated after a temporary bonding is firstly performed and before a main bonding is secondarily performed.

[0138] Here, although the fabric 3 may be manually separated, as illustrated in FIG, 14, a suction hole 50d may be formed in the upper mold 50b of the first the other side press device 52a, and a suction pump 50e connected to the suction hole 50d through a pipe may be provided in order to improve a productivity.

[0139] In this case, when the upper mold 50b moves upward after the pressing is finished, a suction force to the fabric 3 may be generated, so that the gripping member 2 and the fabric are easily detached.

[0140] In addition, although not shown, a blower for blowing the fabric 3 in a side direction to prevent the fabric 3 from falling to an upper portion of the lower mold 50a when an operation of the suction pump 50e is stopped.

[0141] As illustrated in FIGS. 9 and 10, the guide device 60 is installed adjacent to one side of the support frame 10 and arranges the fabric 3 at an exact position of the outside of the sock main body 1.

[0142] Specifically, the guide device 60 includes a movable frame 61 that vertically moves toward the mold 40 with the sock main body 1 fitted, and a fabric guide member 62 in which a guide hole 62a is formed and which guides an arrangement position of the fabric 3 on the sock main body 1 fitted to the mold 40 is installed on the movable frame 61.

[0143] As the movable frame 61 moves downward when the mold 40 is disposed below the guide device 60, and the fabric guide member 62 is disposed above the sock main body 1 by the downward movement of the movable frame 61, a worker inputs the fabric 3 through the guide hole 62a above the sock main body 1, so that the fabric 3 is disposed at the exact position.

[0144] Also, as the movable frame 61 moves upward in order to perform a next process, and the rotation table 20 rotates, so that the mold 40 moves to the the other side press device 52, the gripping member 2 at the outside of the sock main body 1 is heated and pressed.

[0145] As illustrated in FIG. 10, since the fabrics are sequentially cut from one roll, and the gripping members 2 on the continuous fabric 3 are alternately arranged along a longitudinal direction thereof, the gripping members 2 disposed on the inner circumferential surface and the outer circumferential surface of the sock main body 1 may be alternately arranged in position.

[0146] When the fabric 3 remained after the gripping member 2 is bonded to the sock main body 1 in the above-described configuration is detached and removed, the gripping member 2 is firstly temporarily bonded to the sock main body 1 and then detached in the first the other side press device 52a in case of the outer circumferential surface of the sock main body 1, and the fabric at the inside of the sock main body 1 is taken out and removed after the outside press process is finished in case of the inner circumferential surface of the sock main body 1.

[0147] According to the above-described configuration, as a plurality of gripping members 2 are arranged with a predetermined gap in a horizontal direction and a vertical direction on each of the fabrics 3 installed on the inside of the sock main body 1 and the fabrics 3 installed on the outside of the sock main body 1 on a plane, one group of grapping members 2 forming one horizontal line may be arranged alternately with one group of grapping members 2 adjacent thereto in the vertical direction, and the gripping members 2 disposed at the inside of the sock main body 1 and the gripping members 2 disposed at the outside of the sock main body 1 may be alternately arranged on the plane.

[0148] The above-described configuration of the present invention is illustrated in FIGS. 13 and 14.

[0149] FIG. 13 is a view illustrating a process of bonding the gripping member 2 to the inside of the sock main body 1, and FIG. 14 is a view illustrating a process of bonding the gripping member 2 to the outside of the sock main body 1.

[0150] As described above, the present invention may exactly and alternately arrange the gripping members 2 on the inside and the outside of the sock main body 1 and have the improved working speed to provide the sock having the excellent non-slip function to various consumers in addition to sports athletes of a specific game.
