Description

Technical Field

[0001] The present invention relates to a device for shoe adhesive, and more particularly, to a device for activating polyurethane resin, which is an adhesive for bonding various parts of a shoe. Background Art

[0002] Usually, shoes are mainly composed of an upper and a sole, and the sole includes an outsole, a midsole, an insole, etc. After each component is made through various manufacturing processes, it is assembled with an adhesive.

[0003] For example, after adhesive (for example, polyurethane resin) is applied to the bonding surface where the parts of the shoe are bonded to each other, the adhesive is activated, and then the parts are bonded to each other. In this case, in order to activate the adhesive, a heating process is usually performed.

[0004] However, the bonding surfaces of the various components of the shoe are generally curved, and in particular, due to the characteristics of the shoe, the shapes of the left and right sides are generally different. Therefore, the curvature and shape of the bonding surface may cause uneven heat transfer to the adhesive. If the heat transferred to the bonding surface is uneven, the bonding strength of the entire bonding surface may deviate, thereby causing a problem of reduced product reliability.

[0005] Therefore, existing operators can only implement a cumbersome process of manually installing each component coated with adhesive into the shoe adhesive activation device one by one, positioning it so that heat is evenly transferred to the entire bonding surface, and then recovering the above components after the heating operation.

[0006] Therefore, the existing shoe adhesive activation operation has problems such as low operation efficiency, increased workload of operators and decreased productivity. Summary of the invention

[0007] In order to solve the above-mentioned problems, the present invention provides a shoe adhesive activation device capable of operating efficiently.

[0008] The present invention provides a shoe adhesive activation device, comprising: a conveyor for transferring outsoles; a drying chamber for the conveyor to pass through; and an outsole adhesive activation unit, which is located behind the drying chamber and on the upper part of the conveyor and is connected to one or more connecting arms extending from an activation unit bracket to change one or more of the horizontal position, vertical position and inclination.

[0009] According to an embodiment of the present invention, by using a shoe adhesive activation device, operators can continuously put in each component in each process and recycle them after the process, rather than putting them in and recycle them individually, thereby improving work efficiency.

[0010] Furthermore, according to an embodiment of the present invention, the position of the shoe adhesive activation unit can be conveniently adjusted and continuously operated without requiring an operator to install each component and adjust the position of the shoe adhesive activation unit one by one in a manner corresponding to the position of the corresponding component.

[0016] The following is a detailed description of the embodiments of the present invention. However, the present invention is not limited to the embodiments disclosed below, and can be implemented in various different implementations. The embodiments are only used to fully disclose the present invention and more completely inform the ordinary technicians in the technical field to which the present invention belongs.

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0018] Figure 1 and Figure 2 Schematic diagram of activation devices according to various embodiments of the present invention.

[0019] exist Figure 1 and Figure 2 In order to explain the present invention, the right side is defined as the front and the left side is defined as the rear based on the schematic diagram of the activation device 1.

[0020] Reference Figure 1 and Figure 2The activation device 1 may include a drying chamber 100 , a conveyor 200 , a last transferring device 300 , an outsole adhesive activation unit 500 , and an upper adhesive activation unit 600 .

[0021] In the activation device 1 , a shoe last transferring device 300 may be included on the upper portion of the stage-shaped device base 10 .

[0022] The shoe last transfer device 300 may be formed into a structure capable of placing the shoe last 3, and the shoe last 3 is combined with the shoe upper to maintain the shape of the shoe upper. In this case, the shoe last transfer device 300 may be continuously circulated and moved in the form of a conveyor on the upper part of the device base 10. Therefore, in the activation device 1, the shoe last transfer device 300 may transfer the shoe upper mounted on the shoe last 3 in a single direction, for example, from the front to the rear in the order of passing through the drying chamber 100 and the activation unit bracket 400.

[0023] In the activation device 1 , a conveyor 200 may be included at an upper portion of the last transferring device 300 .

[0024] In the activation device 1, the conveyor 200 may transfer the outer sole 2 in a single direction, for example, from the front to the rear in the order of passing through the drying chamber 100 and the activation unit support 400. In this case, the conveyor 200 may be a belt type or a roller type, but is not limited thereto.

[0025] As a component constituting the bottom of the shoe, the outsole 2 may include a sole and a midsole. Also, in the outsole 2, the upper surface of the outsole 2 may be uneven, forming a curved surface.

[0026] like Figure 2 As shown, in the conveyor 200, the first conveyor 200a ( Figure 2 ) and a second conveyor 200b ( Figure 2 ) can be separated and driven independently of each other. Therefore, the first conveyor 200a ( Figure 2 ) and the speed of the second conveyor 200b ( Figure 2 ) speed to adjust the transfer speed of the outsole 2, thereby effectively activating the adhesive applied to the outsole 2.

[0027] For example, the first conveyor 200a ( Figure 2 ) enables the first conveyor 200a ( Figure 2 ) is less than the speed of the second conveyor 200b ( Figure 2) so as to effectively dry the primer applied to the outer sole 2 and effectively preheat the outer sole 2 and the adhesive applied to the outer sole 2. Figure 2 ) can make the second conveyor 200b ( Figure 2 ) is faster than the first conveyor 200a ( Figure 2 ) in order to avoid deformation of the outsole 2 passing through the outsole adhesive activation unit 500 due to excessive transfer of heat applied through the outsole adhesive activation unit 500, but is not limited thereto.

[0028] The drying chamber 100 is a device for heating the upper and the outer sole 2 to dry the upper mounted on the shoe last 3 and the primer applied to the outer sole 2. For example, the drying chamber 100 can heat the interior of the drying chamber 100 using an infrared lamp, a halogen lamp, heat rays, and hot air, but is not limited thereto.

[0029] The outsole adhesive activation unit 500 may be located behind the drying chamber 100 and on the upper portion of the conveyor 200 to activate the adhesive applied to the outsole 2. For example, the outsole adhesive activation unit 500 may include a plurality of lamps that emit heat and light so that the adhesive applied to the outsole 2 may be melted and activated by heating it.

[0030] The outsole adhesive activating unit 500 can be connected to one or more connecting arms connected to the activating unit bracket 400, and the horizontal position, vertical position and inclination can be changed by the connecting arms. Therefore, the outsole adhesive activating unit 500 can change the position of the outsole adhesive activating unit 500 in a manner corresponding to the position of the outsole 2 placed on the upper end of the conveyor 200, and can change the inclination in a manner corresponding to the shape of the outsole 2 to effectively heat the adhesive applied to the outsole 2. This will be described later. Figure 3 and Figure 4 Let me explain in detail.

[0031] The upper adhesive activation unit 600 may be located behind the drying chamber 100 and at the bottom of the conveyor 200, thereby activating the adhesive applied to the upper that is combined with the last 3 installed and moved on the last transfer device 300. For example, the upper adhesive activation unit 600 may include a plurality of lamps that emit heat and light so that the adhesive applied to the upper may be melted and activated by heating it.

[0032] The upper adhesive activation unit 600 can be connected to one or more connecting arms connected to the activation unit bracket 400, and the horizontal position, vertical position and inclination can be changed through the connecting arms. Therefore, the upper adhesive activation unit 600 can change the position of the upper adhesive activation unit 600 in a manner corresponding to the position of the upper, and the upper is combined with the shoe last 3 installed on the shoe last transfer device 300 and moved, and the inclination can be changed in a manner corresponding to the shape of the upper to effectively heat the adhesive applied to the upper.

[0033] The detection unit 700 may be located between the drying chamber 100 and the activation unit support 400, and is used to confirm at least one of the position and shape of the outsole 2 moving at the upper end of the conveyor 200. For example, the detection unit 700 may include a detection sensor such as a visual sensor, a photoelectric sensor, an infrared sensor, and a laser sensor to confirm at least one of the position and shape of the outsole 2. Therefore, the position detection may be performed using the position and shape data of the outsole 2 located at the upper end of the conveyor 200 measured in the detection unit 700, that is, the movement control including the horizontal position, vertical position, and inclination of the outsole adhesive activation unit 500 may be performed.

[0034] For example, the above-mentioned movement control can be performed automatically or manually.

[0035] For example, the above-mentioned detection sensor can be used to identify at least one of the position and shape of the outer sole 2, and the above-mentioned movement control can be automatically performed by a control unit provided with a central processing unit (CPU) etc. Specifically, the optimal heating angle can be set by reflecting at least one of the position and shape of the outer sole 2, and the driving of the connecting arm 510 described later can be automatically controlled according to the position change of the outer sole 2.

[0036] For example, the movement control may be performed according to a preset algorithm. For example, according to the shape of the outer sole 2, the algorithm for the movement control method may be pre-stored in the control unit, and when the detection sensor recognizes the entry of the outer sole 2, the position and inclination of the activation unit 500 may be controlled according to the preset algorithm, that is, the movement of the connecting arm 510 may be controlled.

[0037] In addition, the detection unit 700 may be used to confirm the position and shape of the shoe upper that is combined with the shoe last 3 that is installed on the shoe last transfer device 300 and moves.

[0038] Figure 3 FIG. 4 is a schematic diagram of an outsole adhesive activation unit according to an embodiment of the present invention.

[0039] Reference Figure 3 , the outsole adhesive activating unit 500 can be connected to the connecting arm 510 extending from the activating unit bracket 400 .

[0040] The connecting arm 510 may include a hydraulic cylinder and one or more joints to change the horizontal position, vertical position, and inclination of the outsole adhesive activating unit 500. For example, the connecting arm 510 may adjust the length of the connecting arm 510 by the hydraulic cylinder, thereby changing the vertical position of the outsole adhesive activating unit 500. Also, like a robot arm, the connecting arm 510 may include an angle-adjustable joint to change the horizontal position, vertical position, and inclination of the outsole adhesive activating unit 500. Therefore, the horizontal position, vertical position, and inclination of the outsole adhesive activating unit 500 may be effectively changed in a manner corresponding to the position and shape of the outsole 2 located at the upper end of the conveyor 200.

[0041] Figure 4 FIG. 1 is a schematic diagram showing the operation of the outsole adhesive activating unit according to an embodiment of the present invention.

[0042] Reference Figure 4 , the outsole adhesive activating unit 500 can be connected to at least one connecting arm 510 extending from the activating unit bracket 400 .

[0043] In the activation unit support 400 through which the conveyor 200 can pass, the upper end of the first connecting arm 510a can be fixed to the left side of the upper end of the activation unit support 400 by a fixed shaft and extend downward, and the upper end of the second connecting arm 510b can be fixed to the right side of the upper end of the activation unit support 400 by a fixed shaft and extend downward. In this case, the first connecting arm 510a and the second connecting arm 510b on the activation unit support 400 can move freely with the fixed shaft as a reference.

[0044] The lengths of the first connecting arm 510a and the second connecting arm 510b may be adjusted by including a hydraulic cylinder.

[0045] A first connection jig driving motor 512a may be installed on the left side of the upper end of the outsole adhesive activating unit 500, and a second connection jig driving motor 512b may be installed on the right side. In this case, the first connection jig driving motor 512a and the second connection jig driving motor 512b may be installed in a direction in which the driving shafts of the first connection jig driving motor 512a and the second connection jig driving motor 512b are oriented parallel to the driving shaft of the conveyor 200.

[0046] The first connection jig 511 a is mounted on the driving shaft of the first connection jig driving motor 512 a , and the second connection jig 511 b is mounted on the driving shaft of the second connection jig driving motor 512 b .

[0047] The upper end of the first connecting fixture 511a is combined with the lower end of the first connecting arm 510a, and a multi-axis joint can be applied to the joint portion. The upper end of the second connecting fixture 511b is combined with the lower end of the second connecting arm 510b, and a multi-axis joint can be applied to the joint portion.

[0048] like Figure 4 As shown in part (a) of FIG. 1 , when the lengths of the first connecting arm 510 a and the second connecting arm 510 b are the same, the outsole adhesive activating unit 500 can be parallel to and horizontal to the upper surface of the conveyor 200 .

[0049] like Figure 4 As shown in part (b), the hydraulic cylinder of the first connecting arm 510a is contracted to adjust the length of the first connecting arm 510a to be smaller than the length of the second connecting arm 510b. When the hydraulic cylinder of the second connecting arm 510b is expanded to adjust the length of the second connecting arm 510b to be larger than the length of the first connecting arm 510a, the position of the part of the outsole adhesive activating unit 500 connected to the first connecting arm 510a rises, and the position of the part of the outsole adhesive activating unit 500 connected to the second connecting arm 510b falls. Therefore, the outsole adhesive activating unit 500 can be tilted to one side, and the outsole adhesive activating unit 500 is tilted at an inclination corresponding to the inclination of the outsole 2 located at the upper end of the conveyor 200.

[0050] As the outsole adhesive activating unit 500 is inclined in a manner corresponding to the inclination of the outsole 2, heat can be effectively transferred to the adhesive applied to the outsole 2, and a specific portion of the outsole 2 can be prevented from being overheated.

[0051] Figure 5 FIG. 1 is a schematic diagram showing the operation of the outsole adhesive activating unit according to an embodiment of the present invention.

[0052] exist Figure 5 In the embodiment, the outer sole 2 can be moved along with the movement of the conveyor 200 according to Figure 5 Part (a) of Figure 5 Part (b) of Figure 5 Move in the order of part (c).

[0053] Reference Figure 5 The outsole adhesive activation unit 500 can use the connection fixture 511 and the connection fixture driving motor 512 to adjust the inclination of the outsole adhesive activation unit 500.

[0054] The connection fixture 511 connected to the lower end of the connection arm 510 can be mounted on the driving shaft of the driving motor 512, and the driving shaft of the driving motor 512 is mounted on the upper end of the outsole adhesive activating unit 500. Therefore, when the driving shaft of the driving motor 512 rotates, the driving motor 512 and the outsole adhesive activating unit 500 combined with the driving motor 512 rotate with the connection fixture 511 as a reference, thereby changing the inclination.

[0055] For example, Figure 5 As shown in part (a) of FIG. 5 , the outsole adhesive activating unit 500 can rotate the driving shaft of the driving motor 512 so that the lower end of the outsole adhesive activating unit 500 faces the outsole 2 approaching from the right side, thereby tilting the outsole adhesive activating unit 500 .

[0056] Afterwards, if Figure 5 As shown in part (b), when the position of the outsole 2 is located at the lower end of the outsole adhesive activation unit 500 as the conveyor 200 moves, the drive shaft of the drive motor 512 can be rotated so that the outsole adhesive activation unit 500 is located at a level with the conveyor 200.

[0057] like Figure 5 As shown in part (c) of FIG. 5 , the outsole adhesive activating unit 500 can rotate the driving shaft of the driving motor 512 to make the lower end of the outsole adhesive activating unit 500 face the outsole 2 moving to the left, thereby tilting the outsole adhesive activating unit 500 .

[0058] Therefore, as the inclination of the outsole adhesive activating unit 500 is adjusted, the outsole adhesive activating unit 500 can expand the heat irradiation range for the outsole 2, thereby effectively utilizing the outsole adhesive activating unit 500. Also, as the inclination of the outsole adhesive activating unit 500 is adjusted, the outsole adhesive activating unit 500 can irradiate heat at an angle suitable for the outsole 2 formed with a higher side surface and a lower inner side surface, thereby effectively activating the adhesive applied to the outsole 2. For example, the angle of the outsole adhesive activating unit 500 can be adjusted so that heat is effectively irradiated to the inner side surface of the outsole 2.

[0059] Figure 6 FIG. 1 is a schematic diagram showing a lamp of an outsole adhesive activation unit according to an embodiment of the present invention.

[0060] Reference Figure 6 , the outsole adhesive activation unit 500 may include a plurality of lamps 501 .

[0061] The lamp 501 can emit heat to heat the solid adhesive (e.g., polyurethane resin) applied to the outsole 2. For example, the lamp 501 can be a short-wave infrared lamp, a sodium lamp, a halogen lamp, a xenon lamp, etc., but is not limited thereto. Therefore, the solid adhesive applied to the outsole 2 can be melted and activated into a liquid or flexible gel state by the lamp 501 of the outsole adhesive activation unit 500, so that after the outsole 2 and the upper are bonded to each other, the activated adhesive is hardened, thereby firmly bonding them.

[0062] The light 501 of the outsole adhesive activating unit 500 can be turned on and off in a manner corresponding to the position of the outsole 2 transferred to the conveyor.

[0063] For example, Figure 6 As shown in part (a) of FIG. 5 , when the outsole 2 is located on the right side of the outsole adhesive activating unit 500 , the light 501 located on the right side of the outsole adhesive activating unit 500 may be in an on state.

[0064] Afterwards, if Figure 6 As shown in part (b), when the position of the outsole 2 is located at the center of the outsole adhesive activation unit 500 as the conveyor moves, the light 501 located on the right side of the outsole adhesive activation unit 500 may be in an off state, and the light 501 located in the center of the outsole adhesive activation unit 500 may be in an on state.

[0065] Afterwards, if Figure 6 As shown in part (c), when the position of the outsole 2 is located on the left side of the outsole adhesive activation unit 500 as the conveyor moves, the light 501 located at the center of the outsole adhesive activation unit 500 may be in an off state, and the light 501 located on the left side of the outsole adhesive activation unit 500 may be in an on state.

[0066] Therefore, the outsole adhesive activating unit 500 can adjust the turning on and off of the lamp 501 in such a manner that only the lamp 501 at the position corresponding to the outsole 2 is turned on, thereby preventing unnecessary waste of power.

[0067] The lamp 501 of the outsole adhesive activation unit 500 can be in various shapes. For example, a U-shaped lamp 501a can be applied to the center of the outsole 2, and formed into a shape corresponding to the inner side of the heel of the outsole 2, thereby increasing the heating area. Therefore, heat can be effectively transferred to the inner side of the heel of the outsole 2 formed with a higher side and a lower inner side, and the adhesive applied to the inner side of the heel of the outsole 2, which is difficult to effectively transfer heat, can be effectively activated.
