Abstract
Description
【Technical Field】 , , , , , 【0004】 【0001】 The present invention relates to an assembly device for manufacturing a shoe washing and drying device that washes and removes mud, soil, etc. adhering to the sole or upper of golf shoes, etc., and dries them. In particular, it relates to a welding assembly device in which some of the main components of the shoe washing and drying device are installed on the operation table of the assembly device and can be assembled by welding. 【Background Art】 【0002】 Generally, the manufacture of a shoe washing and drying device involves installing some of the main components of the shoe washing and drying device on a fixed operation table, with one person supporting the installed main components and another person welding to assemble them. However, for a device that can wash and dry shoes simultaneously by multiple people, since its main components are large and heavy, the burden of supporting the main components and, furthermore, the burden of taking an unreasonable welding posture to access the welding points was large. Therefore, it has been required to rotate the operation table so that welding can be easily performed. 【Disclosure of the Invention】 【Problems to be Solved by the Invention】 【0003】 However, there is a risk of mechanical problems such as stably rotating a long and heavy operation table according to the welding posture and, furthermore, the operation table being twisted when rotating the long and heavy operation table from only one location on one side. In addition, from the perspective of stable welding operation, it is required to prevent the operation table from unexpectedly rotating while welding the assembly parts of the shoe washing and drying device on the operation table. Therefore, it has been difficult to realize an operation table that can be rotated. 【Means for Solving the Problems】 【0004】 The object of the present invention is to solve such problems, and the specific means are as follows. (1) In order to solve the above problem, a welding assembly apparatus having an operating table for assembling a shoe washing and drying apparatus by welding, wherein the welding assembly apparatus is A drive unit including one motor, The left second transmission unit and the right second transmission unit are arranged on the left and right sides of the control panel and transmit the rotation of the drive unit, A first transmission unit having a first pivot shaft and a second pivot shaft, located between the drive unit and the left second transmission unit and the right second transmission unit, which transmit the rotation of the drive unit to the left second transmission unit and the right second transmission unit, A left control stand rotating part and a right control stand rotating part are provided at the respective ends of the left second transmission part and the right second transmission part, respectively, and rotate the control stand. The system comprises the aforementioned control panel and a control panel section including a left control panel holder and a right control panel holder that hold the control panel from the left and right sides, The left control panel rotating unit and the right control panel rotating unit are characterized by rotating the control panel simultaneously with the same movement. 【0005】 With the invention described in (1) above, the left and right operating table rotating parts rotate the operating table simultaneously in the same motion from both directions, thus eliminating the risk of the operating table twisting. 【0006】 (2) In the above (1), the second pivot shaft of the first transmission unit is mechanically connected to the left second transmission unit and the right second transmission unit, respectively, so that the left second transmission unit and the right second transmission unit move simultaneously and in the same way. 【0007】 As a result of the invention described in (2) above, the left second transmission unit and the right second transmission unit can move simultaneously and in the same way, and since the left operating platform rotating unit and the right operating platform rotating unit are provided at the respective ends of the left second transmission unit and the right second transmission unit, the left second transmission unit and the right second transmission unit and the left operating platform rotating unit and the right operating platform rotating unit can move simultaneously and in the same way. 【0008】 (3) In the above (2), a bevel gear is used for the mechanical connection between the second pivot shaft of the first transmission unit and the left second transmission unit and the right second transmission unit. 【0009】 With the invention described in (3) above, the second rotating shaft is mechanically connected to the left second transmission unit and the right second transmission unit by bevel gears, respectively, so that the left second transmission unit and the right second transmission unit can be reliably made to move simultaneously in the same way. The bevel gears can also be miter gears in which the number of teeth of the intersecting bevel gears are the same. 【0010】 (4) In the above (1), the left operating stand rotating part and the right operating stand rotating part are each characterized by being reverse-preventing worm gears. 【0011】 According to the invention described in (4) above, the operating table rotation part is configured as a worm gear consisting of a worm and a worm wheel. This configuration is a reverse-prevention gear that prevents the worm from being rotated from the worm wheel side, thus preventing the operating table from moving unexpectedly during welding work and ensuring stable welding operation. 【0012】 (5) In the above (1), a helical gear is arranged at the output end of the drive unit in order to adjust the height difference in the connection between the first transmission unit and the first pivot shaft. 【0013】 With the invention described in (5) above, by using helical gears to adjust the height difference in the connection between the output end of the drive unit and the first rotating shaft, the meshing ratio between the gears is increased, and the strength of the tooth surface can be made higher than that of spur gears. [Brief explanation of the drawing] 【0014】 [Figure 1] A perspective view showing one embodiment of the welding and assembly apparatus for the shoe washing and drying apparatus of the present invention. [Figure 2] This is a perspective view of the overall structure of a shoe washing and drying machine. [Figure 3]This is a disassembled perspective view of the entire structure of a shoe washing and drying machine. [Figure 4] This figure shows the configuration of the pivot shaft that transmits the rotation of the welding assembly device shown in Figure 1. [Best Mode for Carrying Out the Invention] 【0015】 In this specification and in the figures, the directions left, right, up, and down refer to the directions when viewed from the front of the welding assembly apparatus, i.e., from the position of the welder shown in Figure 1. 【0016】 Figure 1 shows one embodiment of the welding assembly apparatus 100 of the shoe washing and drying apparatus of the present invention. This welding assembly apparatus 100 is a device for which the components of the shoe washing and drying apparatus are placed in order on an operating table 650, and a welder assembles them by welding from around the operating table 650, ultimately creating the overall frame 1 of the shoe washing and drying apparatus. 【0017】 Before describing the welding assembly apparatus 100, we will describe the overall frame 1 of the shoe washing and drying apparatus assembled by this welding assembly apparatus 100. Figure 2 is a perspective view of the overall frame of a typical shoe washing and drying apparatus. This overall frame 1 consists of 10 parts: a left plate 11, a right plate 12, a drainpipe 13, a rear wall 14, a bottom wall 15, a support frame 16, a support rail 17, a left partition plate 18, a right partition plate 19, and a bottom rail 20. 【0018】 Once the assembly of the overall frame 1 is complete, the necessary washing platform, footrest, drying platform, and grid-like plate for the shoe washing and drying device are installed, the water and air supply piping required for washing and drying is installed inside the rear wall 14, and the water tap and blower are placed in a location easily accessible to the user, thereby completing the shoe washing and drying device. 【0019】 Figure 3 is an exploded perspective view of the overall skeleton 1 of the shoe washing and drying device. The overall skeleton 1 is composed of 10 parts. These parts are sequentially placed on the operating table 650 of the welding and assembly device 100, and the overall skeleton 1 is assembled by temporary welding, and then completed by final welding. The order of assembling the parts is not particularly determined. Due to the size of the shoe washing and drying device from the single-person type to the multi-person type, the number and size of the parts of the overall skeleton 1 are different, so it can be appropriately determined in consideration of the ease of assembly. 【0020】 The configuration of the welding and assembly device 100 of the present invention is shown in FIG. 1. The welding and assembly device 100 is a device that can freely adjust the inclination of the operating table 650 so that the welder can be in a convenient welding orientation during the process of installing the parts of the overall skeleton 1 of the shoe washing and drying device on its operating table 650 and assembling them by welding to form the overall skeleton 1. In addition, the welder can perform welding operations not only from the position shown in FIG. 1 but also from the opposite side of the operating table 650. The welding and assembly device 100 mainly includes a drive unit 200, a first transmission unit 300, a left second transmission unit 400, a right second transmission unit 450, a left operating table rotation unit 500, a right operating table rotation unit 550, and an operating table unit 600. 【0021】 Referring also to FIG. 4, which shows the configuration of the rotating shaft that transmits the rotation of the drive unit 200 of the welding and assembly device in FIG. 1 to the left operating table rotation unit 500 and the right operating table rotation unit 550, an explanation will be given of how the rotation of the drive unit 200 is transmitted to the operating table unit 600. 【0022】 The drive unit 200 includes a motor 201 and a drive-side spur gear 202 provided on the output shaft of the motor. The motor 201 can be switched between forward rotation and reverse rotation by the operation of the welder. By this forward rotation and reverse rotation, the inclination of the welding table 650 located at the center of the welding table unit 600 can be adjusted to a direction that is easy for the welder to weld through the first transmission unit 300, the left second transmission unit 400, the right second transmission unit 450, the left operation table rotation unit 500, and the right operation table rotation unit 550. The drive-side spur gear 202 is used to adjust the level of the output shaft on the motor side and the level of the first rotation shaft 310 on the first transmission unit side when transmitting the rotation of the motor 201 to the first transmission unit 300. By using spur gears, the meshing rate between the gears can be increased, and the strength of the tooth surface can be made higher than that of spur gears. 【0023】 The first transmission unit 300 mainly includes a first rotation shaft 310 and a second rotation shaft 350, and the rotation of the motor 201 is transmitted to the first rotation shaft 310. A first transmission-side spur gear 302 that meshes with the drive-side spur gear 202 is provided at the drive unit side end of the first rotation shaft 310. The rotation of the first rotation shaft 310 is transmitted to the second rotation shaft 350 that extends horizontally at an angle of 90° with the first rotation shaft. A bevel gear is used for the engagement between the first rotation shaft and the second rotation shaft (see Fig. 4). A first rotation shaft side bevel gear 303 on the first rotation shaft side and a second rotation shaft side first bevel gear 351 on the second rotation shaft side are meshing at an angle of 90°. 【0024】 The rotation of the second drive shaft 350 is transmitted to the left second transmission section 400 and the right second transmission section 450, which extend perpendicularly to the second drive shaft at a 90° angle. The left second transmission section mainly consists of the left first drive shaft 410 and the left second drive shaft 420, while the right second transmission section mainly consists of the right first drive shaft 460 and the right second drive shaft 470. On the left second transmission section side, the left first bevel gear 401 is provided at the lower end of the left first drive shaft 410 and meshes with the second bevel gear 352 on the second drive shaft side of the second drive shaft 350. The left second bevel gear 402 is provided at the upper end of the left first drive shaft 410 and meshes with the left third bevel gear 403 at a 90° angle. Similarly, on the right second transmission side, a right first bevel gear 451 is provided at the lower end of the right first pivot shaft 460 and meshes with the second pivot shaft side third bevel gear 353 of the second pivot shaft 350. A right second bevel gear 452 is provided at the upper end of the right first pivot shaft 460 and meshes with the right third bevel gear 453 at a 90° angle. 【0025】 The left second transmission unit 400 is provided with a left control stand rotating unit 500 at its tip, and the right second transmission unit 450 is provided with a right control stand rotating unit 550 at its tip. The left control stand rotating unit mainly consists of a left worm wheel 510 and a left worm 520, while the right control stand rotating unit mainly consists of a right worm wheel 560 (not shown) and a right worm 570 (shown in Figure 4). 【0026】 The left worm 520 is directly connected to the left second pivot shaft 420 and rotates simultaneously with the left second pivot shaft 420 in the same direction. The left worm 520 forms a worm gear with the left worm wheel 510. That is, for example, when the left worm 520 rotates clockwise, the left worm wheel 510 rotates in a certain direction, and when the left worm 520 rotates counterclockwise, the left worm wheel 510 rotates in the opposite direction. However, due to the characteristics of the worm gear, it is configured with an anti-reverse gear that prevents the left worm 520 from being rotated by the left worm wheel 510, thus preventing the operating table 650 from moving unexpectedly during welding and ensuring stable welding operation. 【0027】 The control platform 600 mainly consists of a left bearing 610 on the left side that receives the left pivot shaft 530, which is the pivot axis of the left worm wheel 510, a left control platform holder 620 that holds the control platform 650 on its left side, a right bearing 660 on the right side that receives the right pivot shaft 580 (not shown), which is the pivot axis of the right worm wheel 560 (not shown), and a right control platform holder 670 that holds the control platform 650 on its right side. 【0028】 The operating table 650 is, for example, roughly rectangular in shape with a width of 950 mm and a length of 4500 mm in plan view, and is supported at both ends in the longitudinal direction by the left operating table holder 620 and the right operating table holder 670. Taking the left side of the operating table 650 as an example, the left bearing 610 and the left operating table holder 620 rotate around the left pivot axis 530 of the left worm wheel 510. Since the left operating table holder 620 is integrated with the operating table 650, the operating table 650 rotates around the left pivot axis 530. The right side of the operating table 650 has the same configuration as the left side, and the operating table 650 is supported at two points on the left and right, and rotates until it is at an angle that is easy for the welder to weld.
