Description

Technical Field

[0001] This utility model relates to the field of roller conveyor positioning, specifically a roller conveyor positioning device with an adjustable stopper. Background Technology

[0002] Roller conveyors are suitable for conveying items with flat bottoms. They mainly consist of transmission rollers, frames, supports, and drive units, and are characterized by large conveying capacity, high speed, and smooth operation.

[0003] According to the publicly available patent CN212075551U, a high-efficiency and energy-saving roller conveyor line with side discharge function, it includes a frame and a roller conveyor line mounted on the frame; the roller conveyor line includes several rollers; it also includes a side discharge mechanism; the side discharge mechanism includes a lifting mechanism and a belt conveyor line mounted on the lifting mechanism; the lifting mechanism drives the belt conveyor line to reciprocate up and down; the belt conveyor line is arranged with rollers spaced apart; the conveying direction of the belt conveyor line intersects with the conveying direction of the roller conveyor line; the technical solution adopted by this utility model solves the problem that existing roller conveyors do not have a structure for side discharge, cannot select and adjust the discharge direction as needed, and have a single discharge direction, resulting in low transportation efficiency.

[0004] In traditional roller conveyor lines, multiple belt conveyors are configured on the roller surface for side discharge of items. However, in practice, due to changes in production processes, equipment layout, or processing requirements, the discharge position often needs frequent adjustments. This frequent repositioning requires operators to repeatedly adjust and replace the overall conveyor layout, increasing operational complexity and time costs, reducing production efficiency, and causing numerous inconveniences in daily operations. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a positioning device for a roller conveyor line with an adjustable stopper. This addresses the problem that in the current use of traditional roller conveyor lines, multiple belt conveyors are configured on the surface of the rollers for discharging materials from the side. However, in actual applications, due to changes in production processes, equipment layout, or processing requirements, the discharge position of the materials often needs to be frequently adjusted according to specific circumstances. This frequent positional change requires operators to repeatedly adjust and replace the overall layout of the conveyor line, which not only increases the complexity and time cost of operation but also reduces production efficiency, bringing many inconveniences to daily operations.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a positioning device for a roller conveyor line with an adjustable stopper is designed, including a first fixed plate and a second fixed plate. Multiple roller bodies are installed between the first fixed plate and the second fixed plate. A first fixed block and a second fixed block are fixed on both sides of the top of the first fixed plate and the second fixed plate. A threaded rod is rotatably provided between the first fixed block and the second fixed block. A movable block passes through the outside of the threaded rod, and the threaded rod is threadedly connected to the threaded hole in the movable block. An adjustable stopper assembly is provided on the top of the movable block.

[0007] Preferably, the adjustable blocking assembly includes a circular groove, inside which a telescopic cylinder is installed. A piston rod is connected to the top of the telescopic cylinder, and a first motor is embedded in the top of the piston rod. The first motor installed on the top of the moving block can drive the fixed frame plate and its internal multiple rotating wheels to move flexibly and adjust their angles, thereby forming a dynamic blocking barrier on the roller surface and precisely controlling the stopping position of the item.

[0008] Preferably, the output shaft at the top of the first motor is connected to a rotating rod via a coupling, and a fixed frame plate is fixed to the top of the rotating rod.

[0009] Preferably, the fixed frame plate has multiple first grooves and second grooves respectively opened at the upper and lower ends, and the multiple first grooves and second grooves are arranged vertically and vertically.

[0010] Preferably, a motor is installed inside the first groove, and a rotating wheel is fixed to the output shaft at the bottom of the motor. A connecting rod is fixed to the bottom of the rotating wheel, and the bottom of the connecting rod extends into the second groove and is rotatably connected to the bearing in the second groove. Multiple rotating wheels installed in the fixed frame are driven by independent motors and rotate synchronously in the same direction. After blocking the item, a directional driving force can be actively applied to push the stuck item out of the roller conveyor line along a preset trajectory. This breaks through the limitations of the traditional passive blocking mode and improves the adaptability and operational flexibility of the device under complex working conditions.

[0011] Preferably, one end of the threaded rod passes through the first fixed block and is connected to the output shaft of the second motor via a coupling. The second motor is mounted on the surface of the first fixed block and drives the moving block to move as a whole through the threaded rod transmission mechanism. This can further adjust the lateral position of the fixed frame plate and the rotating wheel assembly, thereby adjusting the blocking position on the roller surface and meeting diverse process requirements.

[0012] Preferably, the other end of the threaded rod passes through the second fixing block and is rotatably connected to the bearing inside the second fixing block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model combines a moving block, a telescopic cylinder, and a fixed frame plate. A first motor mounted on the top of the moving block drives the fixed frame plate and its internal rotating wheels to move flexibly and adjust their angles, thus forming a dynamic blocking barrier on the roller surface and precisely controlling the stopping position of the item. Simultaneously, a threaded rod transmission mechanism drives the moving block to translate as a whole, further adjusting the lateral position of the fixed frame plate and rotating wheel assembly, achieving adjustment of the blocking position on the roller surface to meet diverse process requirements. Furthermore, the multiple rotating wheels installed inside the fixed frame plate are driven by independent motors and rotate synchronously in the same direction. After blocking the item, they can actively apply a directional driving force to push the stuck item along a preset trajectory. The roller conveyor line breaks through the limitations of the traditional passive blocking mode, improves the adaptability and operational flexibility of the device under complex working conditions, and solves the problem of the current use of traditional roller conveyor lines. The roller surface is equipped with multiple belt conveyors for discharging materials from the side. However, in actual application, due to changes in production process, equipment layout or processing requirements, the discharge position of the materials often needs to be frequently adjusted according to the specific situation. This frequent position change requires the staff to repeatedly adjust and replace the overall layout of the conveyor line, which not only increases the complexity and time cost of operation, but also reduces production efficiency and brings many inconveniences to daily operation.

[0015] 2. This utility model combines double fixed frame plates and rotating wheels. The moving block can control the position and angle of multiple fixed frame plates and rotating wheels. By setting multiple blocking points at different positions on the roller conveyor line, it can achieve precise single-point interception and also build multi-level buffer barriers to adapt to complex sorting needs. For large-volume items, the device can link two sets of fixed frame plates to adjust them to the same angle to form a guide channel. The double frame plates stably clamp the items, and the two sets of rotating wheels drive in the same direction to transform passive interception into active conveying. This ensures the stability of the large items during transportation and allows for flexible adjustment of their movement trajectory. It overcomes the limitations of traditional devices in handling large-sized goods and improves the operating efficiency and applicability under complex working conditions.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0021] Example 1

[0022] A positioning device for a roller conveyor line with an adjustable stopper, see [link / reference]. Figures 1 to 3 The system includes a first fixed plate 1 and a second fixed plate 102. Multiple roller bodies 101 are installed between the first fixed plate 1 and the second fixed plate 102. First fixed blocks 2 and second fixed blocks 203 are fixed to both sides of the top of the first fixed plate 1 and the second fixed plate 102. A threaded rod 202 is rotatably provided between the first fixed block 2 and the second fixed block 203. A movable block 204 passes through the outside of the threaded rod 202, and the threaded rod 202 is threadedly connected to a threaded hole 207 in the movable block 204. An adjustable blocking component is provided on the top of the movable block 204. When it is necessary to block items on the roller conveyor line, the piston rod 210 is extended by the telescopic cylinder 209, causing the fixed frame plate 205 to rise to an appropriate height. Then, the first motor... The drive rod 211 rotates the rotating rod 212 and the fixed frame plate 205 to the required angle, forming a dynamic barrier to precisely control the stopping position of the item. This solves the problem that in the current use of traditional roller conveyor lines, multiple belt conveyors are configured on the roller surface for discharging items from the side. However, in actual applications, due to changes in production processes, equipment layout, or processing requirements, the discharging position of the item often needs to be frequently adjusted according to specific circumstances. This frequent position change requires the staff to repeatedly adjust and replace the overall layout of the conveyor line, which not only increases the complexity and time cost of operation but also reduces production efficiency and brings many inconveniences to daily operations.

[0023] For details, see Figure 2 The adjustable blocking assembly includes a circular groove 208, inside which a telescopic cylinder 209 is installed. A piston rod 210 is connected to the top of the telescopic cylinder 209, and a first motor 211 is embedded in the top of the piston rod 210.

[0024] Further, see Figure 2The output shaft at the top of the first motor 211 is connected to a rotating rod 212 via a coupling, and a fixed frame plate 205 is fixed to the top of the rotating rod 212.

[0025] It is worth mentioning that, see Figure 1 One end of the threaded rod 202 passes through the first fixed block 2 and is connected to the output shaft of the second motor 201 via a coupling. The second motor 201 is mounted on the surface of the first fixed block 2.

[0026] It is worth emphasizing that, see Figure 1 The other end of the threaded rod 202 passes through the second fixing block 203 and is rotatably connected to the bearing inside the second fixing block 203.

[0027] Example 2

[0028] See Figure 3 The fixed frame plate 205 has multiple first grooves 3 and second grooves 303 at its upper and lower ends, respectively, and the multiple first grooves 3 and second grooves 303 are arranged vertically and vertically. A motor 301 is installed inside the first groove 3. A rotating wheel 206 is fixed to the output shaft at the bottom of the motor 301. A connecting rod 302 is fixed to the bottom of the rotating wheel 206. The bottom of the connecting rod 302 extends into the second groove 303 and is rotatably connected to the bearing in the second groove 303. The second motor 201 drives the threaded rod 202 to rotate, which drives the moving block 204 and the adjustable blocking assembly to move as a whole, so as to realize the flexible adjustment of the blocking position on the roller surface. In this section, the fixed frame plate 205 has a first groove 3 and a second groove 303 at its upper and lower ends. A motor 301 is installed in the first groove 3. Multiple motors 301 drive the rotating wheels 206 to rotate synchronously in the same direction. After the item is blocked, a directional driving force can be actively applied to push the stuck item out of the roller conveyor line along a preset trajectory, thereby realizing the active conveying of the item. For large items, the two sets of fixed frame plates 205 can be linked together to adjust them to the same angle to form a guide channel. The double frame plates are used to stably clamp the item, and the stable conveying and trajectory adjustment of large items are realized through the coordinated drive of the two sets of rotating wheels 206.

[0029] It should be noted that in this application, multiple motors 301 are connected to an external synchronous controller. Through the precise control of the synchronous controller, multiple motors 301 can achieve synchronous rotation in the same direction, thereby driving the rotating wheel 206 to rotate synchronously in the same direction. To ensure the coordination and accuracy of the device operation, a synchronous controller of model SIMOCODE pro VDP manufactured by Siemens is used. The actual product can be selected according to the latest market conditions and technical requirements.

[0030] In a roller conveyor positioning device with an adjustable stopper, when it is necessary to stop items on the roller conveyor, the telescopic cylinder 209 drives the piston rod 210 to extend, causing the fixed frame plate 205 to rise to an appropriate height. Then, the first motor 211 drives the rotating rod 212 and the fixed frame plate 205 to rotate to the required angle, forming a dynamic blocking barrier to precisely control the stopping position of the items. The second motor 201 drives the threaded rod 202 to rotate, causing the moving block 204 and the adjustable blocking assembly to move as a whole, realizing flexible adjustment of the blocking position on the roller surface. The inner upper and lower ends are provided with a first groove 3 and a second groove 303. A motor 301 is installed in the first groove 3. Multiple motors 301 drive the rotating wheels 206 to rotate synchronously in the same direction. After the object is blocked, a directional driving force can be actively applied to push the stuck object out of the roller conveyor line along a preset trajectory, thereby realizing the active conveying of the object. For large-volume objects, two sets of fixed frame plates 205 can be linked to adjust them to the same angle to form a guide channel. The double frame plates are used to stably clamp the object, and the stable conveying and trajectory adjustment of large objects are realized through the coordinated drive of the two sets of rotating wheels 206.
