The protective cylinder is horizontally arranged in the bracket, the rollers are rotatably and concentrically arranged in the protective cylinder, a feed inlet is arranged at the top of the protective cylinder, a blanking outlet is arranged at the bottom of the protective cylinder, the steel pipe temporary storage box is arranged above the feed inlet, a hopper connected to the feed inlet is arranged at the bottom of the steel pipe temporary storage box, the partition plate can move along the length direction of the steel pipe temporary storage box, the partition plate is vertically arranged in the steel pipe temporary storage box, and embedding grooves corresponding to the steel pipes are arranged at intervals on the outer circumference of the rollers; in the steel pipe blanking control mechanism in this patent, the axial limit of the steel pipes is carried out by the movement of the partition plate along the length direction of the steel pipe temporary storage box, improving the adaptability to the lengths of different batches of steel pipes, and the steel pipes are blanked one by one by the rotation of the rollers driving the embedding grooves.

[0004] When the above technical solution is used for steel pipe blanking, the steel pipes fall from the steel pipe temporary storage box by gravity. For square pipes, during the blanking process, it is very easy for two pipes to get stuck at the bottom discharge port of the steel pipe temporary storage box, resulting in the situation where blanking cannot be carried out smoothly. Summary of the Invention

[0005] The present invention provides a temporary storage device for ladder production, aiming to solve the problem that in the related technology, during the blanking process of square pipes, it is very easy for two pipes to get stuck at the discharge port, resulting in the inability to carry out smooth blanking.

[0006] A temporary storage device for ladder production, including a material box, the bottom of the material box is provided with a discharge port, and further includes a rotating body, two blanking control components and a driving component. The rotating body is rotatably installed at the bottom of the material box. Two receiving grooves are provided on the outer peripheral surface of the rotating body, and the two receiving grooves are symmetrical about the rotation center of the rotating body. The two blanking control components are respectively arranged at the two receiving grooves. The blanking control component includes two guiding frames, and the two guiding frames are respectively arranged on both sides of the receiving groove. The guiding frame includes a first guide rod, a second guide rod, a positioning frame and a transmission belt. Both the first guide rod and the second guide rod are slidably connected to the rotating body. The sliding direction of the first guide rod is the same as the arrangement direction of the two receiving grooves. The second guide rod is located outside the first guide rod and can rotate in a cycle. The two ends of the positioning frame are respectively rotatably connected to the first guide rod and the second guide rod. The transmission belt is looped on the outer peripheral sides of the first guide rod and the second guide rod, so that the first guide rod and the second guide rod can rotate synchronously. The driving component can drive the first guide rod to slide, and when the first guide rod slides, the second guide rod can rotate in a cycle.

[0007] The beneficial effects of the present invention are as follows: When the square pipe is taken out of the material box in the present invention, by controlling the sliding of the first guide rod and the cyclic rotation of the second guide rod, the two second guide rods in the blanking control component can extend into the material box, and the pipe can be clamped between the transmission belts, so that the pipe can be smoothly taken out of the material box, and the situation that two pipes are stuck at the discharge port of the material box and cannot be smoothly discharged will not occur, which is convenient to use.

[0008] Preferably, the rotating body is provided with a groove corresponding to the end of the second guide rod. A triangular fixing block is fixedly arranged in the groove. A ring groove is formed on the outer peripheral side of the fixing block, and the ring groove is triangular. The second guide rod can rotate in a cycle in the ring groove. The effect is that the triangular ring groove can limit the second guide rod to facilitate the cyclic rotation of the second guide rod.

[0009] Preferably, a baffle is rotatably connected to the corner of the fixing block facing the inner side of the rotating body. The area between the two second guide rods is defined as the feeding port. The free end of the baffle is biased towards the feeding port. A torsion spring is connected between the baffle and the rotating body. The effect is that when the second guide rod starts to slide from the fixing block towards the inner corner of the rotating body, the baffle can ensure that the second guide rod can slide towards the side away from the baffle.

[0010] Preferably, on the opposite outer side surfaces of the two fixing blocks corresponding to the blanking control components, a first rack is provided on each. A gear for meshing with the first rack is fixedly installed on the second guide rod. The effect is that when the second guide rod slides and the gear meshes with the first rack, it can drive the transmission belt to rotate, facilitating the control of the pipe in the material box to move between the two guiding frames.

[0011] Preferably, racks two for engaging with the gear are provided on the upper side surfaces of the two fixing blocks.

[0012] Preferably, among the two inner side surfaces of the two fixing blocks facing each other, a rack three for engaging with the gear is provided on one inner side surface, and a rack four for engaging with the gear is provided on the side surface of the annular groove facing the other inner side surface.

[0013] Preferably, an elastic member is arranged between the two guide rods two in the blanking control assembly. The two ends of the elastic member are respectively rotatably connected to the two guide rods two. The effect is that when the distance between the two guide rods two gradually increases to a set state, the stretched elastic member can drive the two guide rods two to gradually approach each other.

[0014] Preferably, the driving assembly includes two connecting members, a lead screw, and a driving member two. The two connecting members respectively correspond to the two blanking control assemblies. The connecting member is rotatably connected to the two guide rods one in the blanking control assembly. The lead screw is rotatably connected to the rotating body, and the length direction of the lead screw is the same as the arrangement direction of the two receiving grooves. The lead screw is in threaded transmission connection with the two connecting members. The driving member two can drive the lead screw to rotate, and when the lead screw rotates, the two connecting members can approach or move away from each other.

[0015] Adopting the above technical solution, the beneficial effect of the present invention is that when the square pipe is taken out of the material box, by controlling the sliding of the guide rod one and the cyclic rotation of the guide rod two, the two guide rods two in the blanking control assembly can extend into the material box, and the pipe can be clamped between the transmission belts, so that the pipe can be smoothly taken out of the material box. Next, control the rotating body to rotate 180°, so that the receiving groove clamping the pipe faces downward, and continue to control the cyclic rotation of the guide rod two. The pipe clamped between the transmission belts will fall on the ladder assembly equipment, that is, the ladder can be assembled on the ladder assembly equipment. Brief Description of the Drawings

[0027] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0028] As Figures 1 to 5 shown, the temporary storage device for ladder production in the embodiment of the present invention includes a material box 1, a rotating body 2, two blanking control components and a driving component. The bottom of the material box 1 is provided with a discharge port. The bottom of the material box 1 has a V-shaped structure. During use, a plurality of cut pipes to be used can be stacked in the material box 1. Only one pipe can fall through the discharge port at a time. The material box 1 is installed on the ladder assembly equipment 7. The pipes falling through the discharge port of the material box 1 will fall on the ladder assembly equipment 7 and the ladder can be assembled on the ladder assembly equipment 7.

[0029] The rotating body 2 is rotatably installed at the bottom of the material box 1. Two receiving grooves 221 are provided on the outer peripheral surface of the rotating body 2. The two receiving grooves 221 are symmetric about the rotation center of the rotating body 2.

[0030] Specifically, the rotating body 2 includes two vertical plates 21 and a shaft body 22 fixedly installed between the two vertical plates 21. The two receiving grooves 221 are symmetrically arranged on the shaft body 22. The axial direction of the shaft body 22 is the same as the length direction of the pipes in the material box 1. The pipes falling through the material box 1 can enter the receiving grooves 221. The bottom of the material box 1 is fixedly connected with a mounting frame 11. The vertical plate 21 is rotatably connected with the mounting frame 11. A driving member 1 5 is fixedly installed on the mounting frame 11. The driving member 1 5 is a motor, and its output end is fixedly connected with the rotating body 2. Controlling the operation of the driving member 1 5 can drive the rotation of the rotating body 2.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] Specifically, the annular groove 212 in a triangular structure is composed of three sequentially connected chutes. The three chutes are respectively defined as chute one 2121, chute two 2122, and chute three 2123. The area between the two guide rods two 32 is defined as the feed inlet. Chute one 2121 is located near the feed inlet, chute two 2122 is located far from the feed inlet, and chute three 2123 is located above chute one 2121 and chute two 2122. The rack one 41 is fixedly arranged on the fixed block 211 corresponding to chute two 2122. The gear 42 is fixedly installed on the guide rod two 32. When the guide rod two 32 moves along chute two 2122, the gear 42 will mesh with the rack one 41, driving the guide rod two 32 to rotate. Through the transmission belt 34, the guide rod one 31 will be driven to rotate. Moreover, when the guide rod two 32 moves from the inner side to the outer side of the rotating body 2 along chute two 2122, the sides of the transmission belt 34 facing the feed inlet all move towards the inner side of the rotating body 2.

[0036] On the upper side surface of the fixed block 211, a rack two 43 for meshing with the gear 42 is fixedly arranged. The rack two 43 is opposite to chute three 2123. When the guide rod two 32 moves along chute three 2123, the gear 42 will mesh with the rack two 43, driving the guide rod two 32 to rotate. Through the transmission belt 34, the guide rod one 31 will be driven to rotate. Moreover, when the guide rod two 32 enters chute three 2123 from chute two 2122 and continues to move in chute three 2123, the sides of the transmission belt 34 facing the feed inlet all move towards the inner side of the rotating body 2.

[0037] Among the two opposite inner side surfaces of the two fixed blocks 211, a rack three 44 for meshing with the gear 42 is provided on one of the inner side surfaces, and a rack four 45 for meshing with the gear 42 is provided on the side surface of the annular groove 212 opposite to the other inner side surface. That is, both the rack three 44 and the rack four 45 face chute one 2121. The rack three 44 is fixedly arranged on the fixed block 211, and the rack four 45 is fixedly arranged on the side surface of the annular groove 212 corresponding to chute one 2121. When the two guide rods two 32 respectively enter chute one 2121 from the corresponding chute three 2123 and continue to move along chute one 2121, the gear 42 on one of the guide rods two 32 will mesh with the rack three 44, driving the corresponding guide rod two 32, transmission belt 34, and guide rod one 31 to rotate. The gear 42 on the other guide rod two 32 will mesh with the rack four 45, driving the corresponding guide rod two 32, transmission belt 34, and guide rod one 31 to rotate. And the moving directions of the sides of the two transmission belts 34 facing the feed inlet are opposite, one side moves towards the inner side of the rotating body 2, and the other side moves towards the outer side of the rotating body 2.

[0038] A baffle plate 47 is rotatably connected to the corner of the fixed block 211 facing the inside of the rotating body 2. The area between the two second guide rods 32 is defined as the feeding port. The free end of the baffle plate 47 biases towards the direction where the feeding port is located. A torsion spring (not shown in the figure) is connected between the baffle plate 47 and the rotating body 2.

[0039] Specifically, one end of the baffle plate 47 is rotatably connected to the fixed block 211, and the other end biases towards the first slideway 2121 under the action of the torsion spring. When the end of the second guide rod 32 is located at the connection of the first slideway 2121 and the second slideway 2122 and starts to move towards the outside of the rotating body 2, the baffle plate 47 can block the second guide rod 32 to ensure that the second guide rod 32 enters the second slideway 2122. And when the second guide rod 32 moves from the inside of the first slideway 2121 towards the connection of the first slideway 2121 and the second slideway 2122, the second guide rod 32 will push the baffle plate 47 to rotate, and the torsion spring will store energy. At this time, the baffle plate 47 no longer blocks the second guide rod 32, and the second guide rod 32 can smoothly enter the connection of the first slideway 2121 and the second slideway 2122.

[0040] An elastic member 46 is arranged between the two second guide rods 32 in the blanking control assembly. The elastic member 46 can be a spring, and its two ends are respectively rotatably connected to the two second guide rods 32. When the second guide rods 32 move along the second slideway 2122 towards the direction of the third slideway 2123, the distance between the two second guide rods 32 in the blanking control assembly gradually increases, and the elastic member 46 will be gradually stretched. When the second guide rods 32 move to the connection of the second slideway 2122 and the third slideway 2123, under the pulling of the elastic member 46, the second guide rods 32 will move along the third slideway 2123, and the distance between the two second guide rods 32 gradually decreases.

[0041] The driving assembly includes two connecting members 61, a lead screw 62 and a second driving member 63. The two connecting members 61 respectively correspond to the two blanking control assemblies. The connecting member 61 is slidably connected to the vertical plate 21, and the sliding direction of the connecting member 61 is the same as the arrangement direction of the two receiving grooves 221. Both of the first guide rods 31 in the blanking control assembly are rotatably connected to the connecting member 61. The lead screw 62 is rotatably connected to the rotating body 2, and the length direction of the lead screw 62 is the same as the arrangement direction of the two receiving grooves 221. The lead screw 62 is in threaded transmission connection with the two connecting members 61, and the spiral directions of the two sections of threads on the lead screw 62 at the connections with the two connecting members 61 are opposite. The second driving member 63 is a motor, and its output end is connected to the lead screw 62 through a gear transmission structure. Controlling the operation of the second driving member 63 can drive the lead screw 62 to rotate. And 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 first guide rod 31 to move synchronously.

[0042] In the initial state of the temporary storage device in this embodiment, the conveyor belts 34 on the two guide frames 3 in the blanking control assembly are in a parallel state, the distance between the two first guide rods 31 is equal to the distance between the two second guide rods 32, and the second guide rods 32 are located at the corners of the annular groove 212 close to the rotation center of the rotating body 2. The pipe size applicable in this embodiment is larger than the size between the conveyor belts 34 on the two guide frames 3 in the parallel state, and the conveyor belts 34 are formed by elastic materials.

[0043] When assembling the ladder, control the first driving member 5 to drive the rotating body 2 to rotate, so that the opening of one of the receiving grooves 221 faces the upper side 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 will face downwards. The following describes the process of the pipe in the material box 1 entering the upper receiving groove 221 based on the movement change of the blanking control assembly corresponding to the upper receiving groove 221:

[0044] Control the operation of the second driving member 63 to move the two connecting members 61 on the vertical plate 21 away from each other, which will drive the first guide rod 31 at the upper accommodation groove 221 to move upward along the chute. Since the first guide rod 31 and the second guide rod 32 are connected by the positioning frame 33, the second guide rod 32 will enter the second chute 2122. When the second guide rod 32 moves along the second chute 2122, the gear 42 will mesh with the first rack 41, driving the second guide rod 32 and the transmission belt 34 to rotate. And the side of the transmission belt 34 facing the feed port will move downward (towards the inner side of the rotating body 2). The second guide rod 32 will gradually enter the material box 1 through the discharge port of the material box 1, and the distance between the two second guide rods 32 in the blanking control assembly will gradually increase, that is, the feed port will gradually increase, and the elastic member 46 will be gradually stretched. The pipes in the material box 1 will enter between the two guide frames 3 through the feed port between the two second guide rods 32. Since the sides of the transmission belts 34 on the two guide frames 3 facing the feed port are both in the downward moving state at this time, under the action of the friction between the transmission belt 34 and the pipes and the gravity of the pipes, the pipes will be driven to move downward. When the second guide rod 32 moves to the connection of the second chute 2122 and the third chute 2123, control the first guide rod 31 to stop moving. Under the pulling of the elastic member 46, the second guide rod 32 will move along the third chute 2123, and the distance between the two second guide rods 32 will gradually decrease. Under the meshing action of the gear 42 and the second rack 43, the transmission belt 34 will continue to rotate, and the transmission belts 34 on both sides of the pipes will apply a downward driving force to the pipes, making the pipes continue to move downward, and the transmission belts 34 on both sides of the pipes will maintain the clamping state of the pipes. When the second guide rod 32 moves to the connection of the third chute 2123 and the first chute 2121, control the first guide rod 31 to move downward, and the second guide rod 32 will move downward along the first chute 2121. Under the meshing action of the gear 42 and the third rack 44, and the gear 42 and the fourth rack 45, the moving directions of the sides of the two transmission belts 34 facing the feed port are opposite, one side will move upward and the other side will move downward, that is, the moving directions of the sides of the transmission belts 34 attached to both sides of the pipes are opposite. During this process, the transmission belt 34 will polish the cutting position at the end of the pipe, and can polish off the chips remaining after cutting the end of the pipe. When the second guide rod 32 moves to the connection of the first chute 2121 and the second chute 2122, the pipes will completely leave the material box 1 and enter the accommodation groove 221. The transmission belts 34 on the two guide frames 3 in the blanking control assembly will return to the parallel state again and maintain the clamping state of the pipes.

[0045] The following describes the process of releasing the pipes clamped in the accommodation groove 221 onto the ladder assembly device 7:

[0046] Control the driving member 1 - 5 to drive the rotating body 2 to rotate, so that the accommodating groove 221 clamping the pipe rotates to a state where the opening faces downward. Then, continue to control the driving member 2 - 63 to operate, so that the two connecting members 61 on the vertical plate 21 move away from each other, driving the first guide rod 31 at the accommodating groove 221 rotated to the lower side to move downward along the sliding groove, which will cause the second guide rod 32 to enter the second sliding track 2122. When the second guide rod 32 moves along the second sliding track 2122 towards the direction of the third sliding track 2123, the distance between the two second guide rods 32 will gradually increase, and the pipe clamped between the transmission belts 34 can fall onto the ladder assembly device 7 under the action of its own gravity. Next, the ladder can be assembled on the ladder assembly device 7.

[0047] Moreover, as can be seen from the above, by moving the two connecting members 61 on the vertical plate 21 away from each other, the blanking control components at the two accommodating grooves 221 can be operated simultaneously, that is, the process of the pipe entering the accommodating groove 221 and the process of releasing the pipe in the accommodating groove 221 can be carried out simultaneously, which can improve the ladder assembly efficiency.

[0048] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
