A discharge port is provided at the bottom of the material box 1, and the bottom of the material box 1 is in a V-shaped structure. When in use, a number of cut pipes to be used can be stacked in the material box 1, and the discharge port can only allow one pipe to fall at a time. The material box 1 is installed on the ladder assembly equipment 7, and the pipes will fall onto the ladder assembly equipment 7 through the discharge port of the material box 1, and the ladder can be assembled on the ladder assembly equipment 7.

[0024] The rotating body 2 is rotatably mounted at the bottom of the material box 1 . Two receiving grooves 221 are arranged on the outer peripheral surface of the rotating body 2 . The two receiving grooves 221 are symmetrical with respect to the rotation center of the rotating body 2 .

[0025] Specifically, the rotating body 2 includes two vertical plates 21 and a shaft body 22 fixedly installed between the two vertical plates 21. Two receiving grooves 221 are symmetrically arranged on the shaft body 22. The axial direction of the shaft body 22 is in the same direction as the length direction of the pipe in the material box 1. The pipe falling through the material box 1 can enter the receiving groove 221. The bottom of the material box 1 is fixedly connected with a mounting frame 11. The vertical plates 21 are rotatably connected to the mounting frame 11. A driving member 5 is fixedly installed on the mounting frame 11. The driving member 5 is a motor, and its output end is fixedly connected to the rotating body 2. The operation of the driving member 5 is controlled to drive the rotating body 2 to rotate.

[0026] The two material unloading control components are respectively arranged at the two receiving grooves 221. The material unloading control components include two guide frames 3. The two guide frames 3 are respectively arranged on both sides of the receiving groove 221. For ease of understanding, the direction where the rotation center of the rotating body 2 is located is defined as the inner direction, and the direction away from the rotation center of the rotating body 2 is defined as the outer direction.

[0027] The guide frame 3 includes a guide rod 1 31, a guide rod 2 32, a positioning frame 33 and a transmission belt 34. The guide rod 1 31 and the guide rod 2 32 are both slidably connected to the rotating body 2. The sliding direction of the guide rod 1 31 is in the same direction as the arrangement direction of the two accommodating grooves 221. The guide rod 2 32 is located on the outside of the guide rod 1 31 and can rotate cyclically. Specifically, a sliding groove adapted to the guide rod 1 31 is provided on the vertical plate 21. The extension direction of the sliding groove is in the same direction as the arrangement direction of the two accommodating grooves 221. The guide rod 1 31 is slidably fitted in the sliding groove. The vertical plate 21 is provided with a groove corresponding to the end of the guide rod 2 32. The groove has a triangular structure and is located on the outside of the sliding groove. A triangular fixing block 211 is fixedly arranged in the groove. A triangular annular groove 212 is formed on the outer peripheral side of the fixing block 211. The guide rod 2 32 is slidably fitted in the annular groove 212 and can rotate cyclically around the annular groove 212.

[0028] The two ends of the positioning frame 33 are respectively connected to the guide rod 1 31 and the guide rod 2 32 for rotation, and the transmission belt 34 is arranged on the outer peripheral side of the guide rod 1 31 and the guide rod 2 32 so that the guide rod 1 31 and the guide rod 2 32 can rotate synchronously. Specifically, the positioning frame 33 is an arc-shaped structure, and the positioning frame 33 can position the distance between the guide rod 1 31 and the guide rod 2 32, so that when the guide rod 1 31 slides, the guide rod 2 32 can rotate in a circle at the same time, and the guide rod 1 31 and the guide rod 2 32 are connected through the transmission belt 34.

[0029] In the two fixed blocks 211 corresponding to the material discharge control assembly, a rack 41 is provided on the opposite outer sides of the two fixed blocks 211, and a gear 42 for meshing with the rack 41 is fixedly installed on the guide rod 2 32.

[0030] Specifically, the triangular ring groove 212 is composed of three slideways connected in sequence, and the three slideways are defined as slideway 1 2121, slideway 2122 and slideway 3 2123, respectively. The area between the two guide rods 2 32 is defined as the feed port. The slideway 1 2121 is located near the feed port, the slideway 2122 is located far from the feed port, and the slideway 3 2123 is located on the upper side of the slideway 1 2121 and the slideway 2 2122. The rack 1 41 is fixedly arranged. On the fixed block 211 corresponding to the slideway 2122, the gear 42 is fixedly installed on the guide rod 2 32. When the guide rod 2 32 moves along the slideway 2122, the gear 42 will engage with the rack 1 41, which will drive the guide rod 2 32 to rotate. Through the transmission belt 34, the guide rod 1 31 will be driven to rotate. Moreover, when the guide rod 2 32 moves along the slideway 2122 from the inside to the outside of the rotating body 2, the side of the transmission belt 34 facing the feed port moves toward the inside of the rotating body 2.

[0031] A rack 2 43 for meshing with the gear 42 is fixedly provided on the upper side surface of the fixed block 211, and the rack 2 43 is directly opposite to the slideway 3 2123. When the guide rod 2 32 moves along the slideway 3 2123, the gear 42 will mesh with the rack 2 43, which will drive the guide rod 2 32 to rotate, and through the transmission belt 34, it will drive the guide rod 1 31 to rotate, and when the guide rod 2 32 enters the slideway 3 2123 from the slideway 2122 and continues to move in the slideway 3 2123, the side of the transmission belt 34 facing the feed port moves toward the inner side of the rotating body 2.

[0032] Of the two inner side surfaces opposite to the two fixing blocks 211, one of the inner side surfaces is provided with a rack 3 44 for meshing with the gear 42, and the side surface of the annular groove 212 directly facing the other inner side surface is provided with a rack 45 for meshing with the gear 42, that is, the rack 3 44 and the rack 4 45 are both facing the slideway 1 2121, the rack 3 44 is fixedly arranged on the fixing block 211, and the rack 4 45 is fixedly arranged on the side surface of the annular groove 212 corresponding to the slideway 1 2121, when the two guide rods 2 32 enter the slideway 1 2121 from the corresponding slideway 3 2123 respectively. When the guide rod 2 is moved inside and continues to move along the slideway 1 2121, the gear 42 on one of the guide rods 2 32 will mesh with the rack 3 44, which will drive the corresponding guide rod 2 32, the transmission belt 34 and the guide rod 1 31 to rotate, and the gear 42 on the other guide rod 2 32 will mesh with the rack 4 45, which will drive the corresponding guide rod 2 32, the transmission belt 34 and the guide rod 1 31 to rotate, and the two transmission belts 34 move in opposite directions toward the side of the feed port, one of the side surfaces moves toward the inner side of the rotating body 2, and the other side surface moves toward the outer side of the rotating body 2.

[0033] A baffle 47 is rotatably connected to the corner of the fixed block 211 toward the inner side of the rotating body 2, and the area between the two guide rods 32 is defined as the feed port. The free end of the baffle 47 is biased toward the direction of the feed port, and a torsion spring (not shown in the figure) is connected between the baffle 47 and the rotating body 2.

[0034] Specifically, one end of the baffle 47 is rotatably connected to the fixed block 211, and the other end is biased toward the slideway 1 2121 under the action of the torsion spring. When the end of the guide rod 2 32 is located at the connection between the slideway 1 2121 and the slideway 2 2122 and begins to move toward the outside of the rotating body 2, the baffle 47 can block the guide rod 2 32 to ensure that the guide rod 2 32 enters the slideway 2 2122, and when the guide rod 2 32 moves from the slideway 1 2121 to the connection between the slideway 1 2121 and the slideway 2 2122, the guide rod 2 32 will push the baffle 47 to rotate, and the torsion spring will accumulate force. At this time, the baffle 47 no longer blocks the guide rod 2 32, and the guide rod 2 32 can smoothly enter the connection between the slideway 1 2121 and the slideway 2 2122.

[0035] An elastic member 46 is arranged between the two guide rods 2 32 in the material discharge control assembly. The elastic member 46 can be a spring, and its two ends are respectively rotatably connected to the two guide rods 2 32. When the guide rod 2 32 moves along the slide 2 2122 to the slide 3 2123, the distance between the two guide rods 2 32 in the material discharge control assembly gradually increases, and the elastic member 46 will be gradually stretched. When the guide rod 2 32 moves to the connection between the slide 2 2122 and the slide 3 2123, under the pulling of the elastic member 46, the guide rod 2 32 will move along the slide 3 2123, and the distance between the two guide rods 2 32 will gradually decrease.

[0036] The driving assembly includes two connecting members 61, a lead screw 62 and a second driving member 63. The two connecting members 61 correspond to the two material discharge control assemblies respectively. The connecting member 61 is slidably connected to the vertical plate 21. The sliding direction of the connecting member 61 is in the same direction as the arrangement direction of the two accommodating grooves 221. The two guide rods 31 in the material discharge control assembly are both rotationally connected to the connecting member 61. The lead screw 62 is rotationally connected to the rotating body 2, and the length direction of the lead screw 62 is in the same direction as the arrangement direction of the two accommodating grooves 221. The lead screw 62 is threadedly connected to the two connecting members 61, and the spiral directions of the two sections of threads on the lead screw 62 at the connection points with the two connecting members 61 are opposite. The driving member 2 63 is a motor, and its output end is connected to the lead screw 62 through a gear transmission structure. The driving member 2 63 is controlled to operate, and the lead screw 62 can be driven to rotate. When the lead screw 62 rotates, the two connecting members 61 can approach or move away from each other. When the connecting member 61 moves, it will drive the guide rod 1 31 to move synchronously.

[0037] In the initial state of the temporary storage device in this embodiment, the transmission belts 34 on the two guide frames 3 in the material discharge control assembly are in a parallel state, the distance between the two guide rods 1 31 is equal to the distance between the two guide rods 2 32, and the guide rod 2 32 is located at the corner of the annular groove 212 close to the rotation center of the rotating body 2. The size of the pipe applicable to this embodiment is larger than the size between the transmission belts 34 on the two guide frames 3 in the parallel state, and the transmission belts 34 are prepared and molded from elastic material.

[0038] When assembling the ladder, the driving member 15 is controlled to drive the rotating body 2 to rotate so that the opening of one of the receiving grooves 221 faces upward and is directly opposite to the discharge port at the bottom of the material box 1, that is, the opening of the other receiving groove 221 faces downward. The following describes the process of the pipe in the material box 1 entering the upper receiving groove 221 by the movement change of the unloading control component corresponding to the upper receiving groove 221: The second driving member 63 is controlled to operate, so that the two connecting members 61 on the vertical plate 21 are separated from each other, which will drive the guide rod 1 31 at the upper receiving groove 221 to move upward along the slide groove. Since the guide rod 1 31 and the guide rod 2 32 are connected by the positioning frame 33, the guide rod 2 32 will enter the second slideway 2122. When the guide rod 2 32 moves along the second slideway 2122, the gear 42 will mesh with the rack 1 41, which will drive the guide rod 2 32 and the transmission belt 34 to rotate, and the side of the transmission belt 34 toward the feed port will move downward (towards the inner side of the rotating body 2), and the guide rod 2 32 will gradually enter the material box 1 through the discharge port of the material box 1. The distance between the two guide rods 32 gradually increases, that is, the feed opening will gradually increase, the elastic member 46 will be gradually stretched, and the pipe in the material box 1 will enter between the two guide frames 3 through the feed opening between the two guide rods 32. At this time, the transmission belts 34 on the two guide frames 3 are in a downward moving state toward the side of the feed opening. Under the action of the friction between the transmission belts 34 and the pipe and the gravity of the pipe, the pipe will be driven to move downward. When the guide rod 2 32 moves to the connection between the slideway 2122 and the slideway 3 2123, the guide rod 1 31 is controlled to stop moving. Under the pulling of the elastic member 46, the guide rod 2 32 will move along the slideway 3 2123 moves, the distance between the two guide rods 2 32 gradually decreases, and under the meshing action of the gear 42 and the rack 2 43, the transmission belt 34 will continue to rotate, and the transmission belts 34 located on both sides of the pipe will apply a downward pushing force to the pipe, so that the pipe continues to move downward, and the transmission belts 34 located on both sides of the pipe will maintain the clamping state of the pipe. When the guide rod 2 32 moves to the connection between the slideway 3 2123 and the slideway 1 2121, the guide rod 1 31 is controlled to move downward, and the guide rod 2 32 will move downward along the slideway 1 2121. Under the meshing action of the gear 42 and the rack 3 44, and the gear 42 and the rack 4 45, the two transmission belts 34 will continue to rotate, and the transmission belts 34 located on both sides of the pipe will apply a downward pushing force to the pipe, so that the pipe continues to move downward, and the transmission belts 34 located on both sides of the pipe will maintain the clamping state of the pipe. When the guide rod 2 32 moves to the connection between the slideway 3 2123 and the slideway 1 2121, the guide rod 1 31 is controlled to move downward, and the guide rod 2 32 will move downward along the slideway 1 2121. The moving direction of the moving belt 34 toward the side of the feed port is opposite, one of the side surfaces will move upward and the other side surface will move downward, that is, the moving directions of the side surfaces of the driving belt 34 attached to the two sides of the pipe are opposite. During this process, the driving belt 34 will grind the cutting position of the end of the pipe, and can grind off the chips remaining after the end of the pipe is cut. When the guide rod 2 32 moves to the connection between the slide 1 2121 and the slide 2 2122, the pipe will completely break away from the material box 1 and enter the receiving groove 221, and the driving belts 34 on the two guide frames 3 in the unloading control assembly will return to a parallel state and maintain the clamping state of the pipe.

[0039] The following describes the process of releasing the pipe clamped in the receiving groove 221 onto the ladder assembly device 7: The driving member 1 5 is controlled to drive the rotating body 2 to rotate, so that the aforementioned receiving groove 221 that clamps the pipe is rotated to a downward opening state, and the driving member 2 63 is continued to be controlled to operate, so that the two connecting members 61 on the vertical plate 21 are moved away from each other, driving the guide rod 1 31 that rotates to the receiving groove 221 on the lower side to move downward along the slide groove, which will make the guide rod 2 32 enter the slideway 2122. When the guide rod 2 32 moves along the slideway 2122 to the direction of the slideway 3 2123, the distance between the two guide rods 2 32 will gradually increase, and the pipe clamped between the transmission belts 34 can fall to the ladder assembly device 7 under the action of its own gravity, and then the ladder can be assembled on the ladder assembly device 7.

[0040] Furthermore, it can be seen from the above that by moving the two connecting pieces 61 on the vertical plate 21 away from each other, the unloading control components at the two receiving grooves 221 can be operated simultaneously, that is, the process of the pipe entering the receiving groove 221 and the process of releasing the pipe in the receiving groove 221 can be carried out simultaneously, which can improve the ladder assembly efficiency.

[0041] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
