[0031] To enable those skilled in the art to better understand the technical solution of the present invention, the present solution will be further described in detail below with reference to specific embodiments.

[0032] like Figures 1 to 5 As shown, this embodiment of the invention provides a railing return device, which includes a return frame 21, a railing output unit 31, a railing input unit 11, a hoisting trolley 41, and a controller. The railing input unit 11 is disposed at the first end 211 of the return frame 21 and is used to input railings into the first end 211. The railing output unit 31 is disposed at the second end 212 of the return frame 21 and is used to output railings from the second end 212. The hoisting trolley 41 is disposed within the return frame 21 and is capable of moving within the return frame 21. The controller is capable of controlling the hoisting trolley 41 to reciprocate between the first end 211 and the second end 212. The hoisting trolley 41 is provided with a fixing structure for connecting with railings.

[0033] The railing return device provided in this embodiment of the invention only requires the railing input unit 11 to input the railing into the first end 211 of the return frame 21, and then fix the railing on the hoisting trolley 41. The controller can control the hoisting trolley 41 and the railing to move together from the first end 211 to the second end 212 of the return frame 21. When the railing is removed from the hoisting trolley 41, the railing output unit 31 outputs the railing from the second end 212. At the same time, under the control of the controller, the hoisting trolley 41 moves from the second end 212 to the first end 211 of the return frame 21 to transport the next railing. This realizes the automatic cyclic handling of railings without the need for manual handling, making the handling of railings more labor-saving.

[0034] like Figure 3 and Figure 4As shown, a first guide rail 12 and a second guide rail 13 are arranged opposite each other within the return frame 21, with the first guide rail 12 and the second guide rail 13 being parallel to each other. The hoisting trolley 41 reciprocates along the first guide rail 12 and the second guide rail 13. This provides good guidance for the hoisting trolley 41 during reciprocating motion and makes its operation relatively stable. It can be understood that the hoisting trolley 41 can achieve movement by sliding with the first guide rail 12 and the second guide rail 13. In this case, the controller can control the drive mechanism to pull the hoisting trolley 41 to slide on the first guide rail 12 and the second guide rail 13 to achieve the above-mentioned reciprocating motion; the hoisting trolley 41 can also achieve movement by rolling with the first guide rail 12 and the second guide rail 13.

[0035] like Figure 5 As shown, the hoisting trolley 41 includes a crossbeam 42 and two mounting blocks 43 respectively disposed at both ends of the crossbeam 42. A drive device 46 is disposed on the mounting block 43. Rollers 44 driven by the drive device 46 are disposed in both mounting blocks 43. Two guide wheels 45 are disposed opposite each other on both sides of the mounting block 43. The controller controls the drive device 46 to drive the rollers 44 to roll on the first guide rail and the second guide rail, thereby realizing the rolling cooperation between the hoisting trolley 41 and the first guide rail and the second guide rail. This makes the movement of the hoisting trolley 41 on the first guide rail and the second guide rail easier to realize. At the same time, the guide wheels 45 can better limit the mounting block 43 and prevent the rollers 44 from disengaging from the first guide rail and the second guide rail, thereby providing better guidance for the movement of the hoisting trolley 41. It is understood that each mounting block 43 can be equipped with a drive device 46, and each drive device 46 is used to drive one roller 44. Alternatively, only one mounting block 43 can be equipped with a drive device 46, and the rollers 44 on the two mounting blocks can be connected by a connecting rod. The drive device 46 drives the connecting rod 493 to rotate, and the connecting rod 493 drives the two rollers 44 to rotate. Preferably, each mounting block 43 can be equipped with two rollers 44, which are respectively located at both ends of the mounting block 43, so as to better realize the rolling cooperation between the hoisting trolley 41 and the first guide rail 12 and the second guide rail 13. Two guide wheels 45 can be respectively provided at both ends of each mounting block 43, so as to play a better role in limiting and guiding between the mounting block 43 and the first guide rail 12 and the second guide rail 13. The drive device 46 can be a motor. Figure 5 The mounting block on the left side has been omitted to better showcase the structure of the roller.

[0036] Furthermore, the hoisting trolley 41 may also include a lifting mechanism 47 and a connecting rod 492 mounted on the crossbeam 42. The fixing structure includes two handles 48 respectively mounted at both ends of the connecting rod 492, which are used to fix to the handles located on both sides of the railing. The power component of the lifting mechanism 47 is connected to a controller; the transmission rod 49 of the power component is connected to the connecting rod 492. The lifting mechanism 47 drives the handles 48 to rise or fall through the connecting rod 492, thereby enabling the controller to control the activation of the power component of the lifting mechanism 47, which in turn drives the handles 48 to be fixed or separated from the handles on both sides of the railing, thus conveniently realizing the fixing and separation of the hoisting trolley 41 from the railing. At the same time, since the hoisting trolley 41 is fixed to the handles on both sides of the railing, it can better avoid contact with the railing body, greatly reducing the wear of the railing body caused during transportation. The power component can be a motor, cylinder, etc.

[0037] To better guide the lifting and lowering of the handle 48, a guide rod 491 can be provided on the connecting rod 492, and a guide hole for the guide rod 491 to pass through is provided on the crossbeam 42. Preferably, there are two guide rods 491 to achieve better guiding effect.

[0038] Specifically, a push rod can be installed on the connecting rod 492. One end of the push rod has a push block 481 for abutting against the top plate of the railing, and the other end of the push rod passes through a through hole on the connecting rod 492 and is connected to a fixing nut. A spring 482 is fitted on the push rod. One end of the spring 482 abuts against the push block 481, and the other end of the spring 482 abuts against the connecting rod 492. Thus, the push rod abuts against the top plate of the railing, thereby effectively preventing the railing from tilting during transportation. It is understood that, depending on the different shapes of the handles on both sides of the railing, the push rod may not be required, provided that the stability of the railing can be guaranteed.

[0039] like Figure 4As shown, in another embodiment of the present invention, the railing return device further includes a first support frame 213, which is perpendicularly connected to the first end 211. The railing input unit includes a slide rail 16, a conveyor plate 15 that slides with the slide rail 16, a transmission mechanism 18, and a drive motor 17. The slide rail is mounted on the first support frame 213 and extends into the first end 211. The drive motor 17 is connected to one end of the transmission mechanism 18, and the conveyor plate 15 is connected to the other end of the transmission mechanism 18. The drive motor 17 drives the conveyor plate 15 to slide on the slide rail 16 through the transmission mechanism 18. With this solution, a front-end robotic arm or robot places the railing on the conveyor plate 15, and then the controller starts the drive motor 17. The transmission mechanism 18 then drives the conveyor plate 15 to transport the railing to the hoisting position in the first end 211. This hoisting position is below the first guide rail 12 and the second guide rail 13, which makes it easier to fix the hoisting trolley 41 to the railing. It is understandable that the drive motor 17 can be set on the first support frame 213 or inside the first end 211, as long as it can drive the conveyor plate 15 to move on the slide rail 16 through the transmission mechanism 18.

[0040] It is understandable that the barricade return device may also include a second support frame, which is vertically connected to the second end 212. The barricade output unit may have the same structure as the barricade input unit, that is, it may also include a slide rail, a conveyor plate, a transmission mechanism, and a drive motor. The slide rail in the barricade output unit is set on the second support frame and extends into the second end 212 so that the barricade can be conveniently conveyed from the second end 212 to the unloading manipulator or robot via the conveyor plate.

[0041] In another embodiment of the present invention, the number of hoisting trolleys 41 can be one or two; a water collection tray 51 is provided inside the return frame 21, located below the first guide rail and / or the second guide rail, and a railing buffer position for storing railings is provided on the water collection tray 51. With this technical solution, when there are two hoisting trolleys 41, one hoisting trolley 41 can first transport the railings to the railing buffer position of the water collection tray 51 inside the return frame 21, and then the other hoisting trolley can transport the railings to the second end 212 of the return frame 21, thereby achieving railing return more quickly and better meeting the high-cycle production requirements of the production line. Simultaneously, when there are excess railings or railings malfunction, the hoisting trolley 41 can place the railing in the railing buffer position. It is understood that the return frame 21 can be connected by multiple end-to-end single frames 24, and each single frame 24 can be provided with a water collection tray 51.

[0042] Furthermore, the hoisting trolley 41 can be equipped with a sensor 61 connected to the controller, and the return frame 21 and / or the first guide rail 12 and / or the second guide rail 13 are equipped with sensing plates 14 for cooperating with the sensor 61; a sensing sensor for detecting whether there is a rail at the rail buffer position is provided, and the sensing sensor is connected to the controller, so that the sensor 61 can feed back the position signal of one of the hoisting trolleys to the controller, so that the controller can control the other trolley to continue transporting the rail, thereby improving the working efficiency of the rail return device. The sensing plates 14 have different codes, and the sensor 61 can know the position of the hoisting trolley 41 through the sensing plates 14; the sensing plates 14 can be installed on at least one of the return frame 21, the first guide rail 12, and the second guide rail 13.

[0043] Specifically, a water collection trough may be provided on the water collection tray 51, and a drain hole for connecting to the drain pipe is provided at the bottom of the water collection trough, so as to collect the dripping water during the transportation of the railing and drain the dripping water.

[0044] The general working process of the railing return device provided by the present invention is as follows: the front-end robotic arm or robot places the railing on the conveyor plate 15 of the railing input unit, the drive motor 17 drives the conveyor plate 15 to slide along the slide rail 16 through the transmission mechanism 18, and transports the railing to the bottom of the first guide rail in the first end; the hoisting trolley 41 moves to the top of the railing in the first end, the lifting mechanism 47 drives the handle 48 to fix the handles on both sides of the railing, lifts the railing from the conveyor plate 15, and then the conveyor plate returns to its original position; the hoisting trolley 41 carries the railing from the first end 211 of the return frame 21 to the second end 212 of the return frame 21, the hoisting trolley 41 releases the railing, the railing output unit 31 outputs the railing from the second end 212, the unloading robotic arm or robot removes the railing, and then the hoisting trolley 41 returns to the first end 211 of the return frame 21.

[0045] It should be noted that the gripper input unit 11 and gripper output unit 31 are not limited to the above structure, that is, they include the slide rail 16, the conveyor plate 15 that slides with the slide rail 16, the transmission mechanism 18 and the drive motor 17; the front-end manipulator or robot can directly place the gripper in the first end 211 so that the hoisting trolley 41 can fix the gripper. At this time, the front-end manipulator or robot is the gripper input unit. Similarly, the unloading manipulator or robot can also directly take out the gripper from the second end 212. At this time, the unloading manipulator or robot is the gripper output unit; of course, the gripper can also be placed in the first end 211 in other ways and then taken out from the second end 212.

[0046] The above are merely preferred embodiments of the present invention. It should be noted that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. Moreover, after reading the contents of the present invention, those skilled in the art can make various modifications or alterations to the present invention, and these equivalent forms also fall within the scope defined by the appended claims.
