Description

Technical Field

[0001] This invention relates to the field of logistics equipment technology, and in particular to a single-motor stacking roller conveyor and a stacking method. Background Technology

[0002] With the rapid development of logistics in my country, many industries have adopted stacking roller conveyors for material transport. In special environments, such as narrow spaces like elevators, new requirements are placed on material transport. Traditional single-motor stacking roller conveyors require five sets of power assemblies to drive the roller conveyor and one set of photoelectric sensors to control one set of power assemblies. This method is cumbersome to install and adjust in limited spaces and is not conducive to the later maintenance of the equipment. Summary of the Invention

[0003] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and its accompanying drawings.

[0004] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a single-motor parallel stacking roller conveyor.

[0005] To achieve the above objectives, the technical solution of the present invention is: a single-motor parallel stacking roller conveyor, comprising a frame and a plurality of conveying rollers, all of which are rotatably connected to the frame, and adjacent conveying rollers are mutually driven. The frame is provided with a power assembly, the output shaft of which is drivenly connected to one of the conveying rollers. The frame is provided with a plurality of photoelectric sensor assemblies, which are spaced apart. One of the photoelectric sensor assemblies is located at the end of the frame, and there is also a space between the other end of the frame and the last photoelectric sensor assembly. The length of each space is equal.

[0006] By adopting the above technical solution and utilizing multiple photoelectric sensor assemblies, materials can be continuously placed in front of the first photoelectric sensor assembly, causing the power assembly to continuously drive all materials forward, thereby completing the stacking. The single-motor stacking roller conveyor only requires adjustment and maintenance of one power assembly, making operation simple and solving the need to transport large-tonnage materials in narrow spaces within elevators.

[0007] Preferably, each of the conveying rollers is provided with a sprocket at one end, and adjacent conveying rollers are interconnected by a chain for transmission. This invention utilizes the meshing of chains and sprockets to achieve the transmission connection between the conveying rollers.

[0008] Preferably, the photoelectric sensor assembly includes a support frame, a support rod, and a mounting bracket. The support frame is fixedly connected to the frame, the support rod is detachably connected to the support frame, and the mounting bracket is connected to the support rod. This invention utilizes the support frame, support rod, and mounting bracket to fix and support the photoelectric sensor.

[0009] Preferably, the support frame has a movable groove, and the support rod passes through the movable groove. The support rod is threaded with two clamping nuts, which are respectively mounted on both sides of the support frame. This invention allows the support rod to be fixed or released by tightening or loosening one of the clamping nuts, thereby adjusting the position of the support rod and changing the spacing to suit the width of the goods.

[0010] Preferably, the mounting bracket has a mounting hole, the support rod passes through the mounting hole, the mounting bracket has a deformation groove that communicates with the mounting hole, and a clamping bolt is threaded through the mounting bracket. This invention allows the mounting bracket to deform at the deformation groove by tightening the clamping bolt, thereby tightening the mounting hole to clamp the support rod and establishing a connection between the mounting bracket and the support rod. Simultaneously, the cooperation between the support rod and the mounting hole allows the mounting bracket and the support rod to rotate, thus adjusting the orientation of the photoelectric sensor.

[0011] Preferably, the support frame has a first fixing hole, and the machine frame has several second fixing holes. The support frame is equipped with a fixing bolt and a fixing nut. The fixing bolt passes through the first fixing hole and one of the second fixing holes, and the fixing nut is threadedly connected to the fixing bolt and pressed against the machine frame. This invention utilizes multiple second fixing holes to allow the support frame to be adjusted in position, thereby accommodating goods of different widths.

[0012] Preferably, a retaining ring is provided at one end of the conveying roller near the frame. This invention utilizes the retaining ring to prevent material from rubbing against the frame.

[0013] Preferably, there are several conveyor rollers without the retaining ring between each conveyor roller equipped with the retaining ring. This method of configuring the retaining rings reduces the number of retaining rings used and lowers costs.

[0014] Preferably, two sets of single-motor parallel stacking roller conveyors are provided, and the two sets of single-motor parallel stacking roller conveyors are arranged symmetrically with each other. By symmetrically arranging two sets of single-motor parallel stacking roller conveyors, the present invention can increase the volume of materials that the roller conveyor can accommodate.

[0015] Preferably, both sets of single-motor stacking roller conveyors are equipped with an alignment mechanism. The alignment mechanism includes a trigger roller, a triggering mechanism, and a trigger switch. The trigger rollers on both sets of single-motor stacking roller conveyors are on the same straight line. The trigger roller includes a rotating shaft, a contact tube, several support pins, and several elastic elements. The rotating shaft is rotatably connected to the frame and is drivenly connected to the conveyor roller. The contact tube is sleeved on the outside of the rotating shaft. The contact tube and the rotating shaft are separated by the support pins. Each support pin is slidably connected to the rotating shaft. Several elastic elements are respectively disposed between each support pin and the rotating shaft. The triggering mechanism includes a roller, a slide, a base, and an elastic element. The base is fixedly connected to the frame, and the slide is slidably connected to the base. The elastic element is disposed between the base and the slide. The roller is rotatably connected to the slide and abuts against the contact tube. The trigger switch is disposed between the slide and the base and abuts against the slide. This invention enables materials on two sets of roller conveyors to align with each other through an alignment mechanism. Specifically, the material is placed on one of the roller conveyors. When the material moves to the trigger roller, the contact tube overcomes the elastic force of the first elastic element under the pressure of the material and pushes the support pin downward. When it moves downward, it pushes the slide block through the roller to overcome the elastic force of the second elastic element, causing the slide block to press the trigger switch. At this time, the power assembly on the roller conveyor will stop working. When the material on the other roller conveyor also presses the trigger roller, the two trigger switches close simultaneously. This condition enables the power assemblies on both roller conveyors to be in working state at the same time. At this time, the two sets of materials can be aligned with each other and transported synchronously.

[0016] A method for stacking roller conveyors, wherein the stacking method employs the single-motor stacking roller conveyor described above, and includes the following steps:

[0017] (1) Adjust the spacing of each photoelectric sensor assembly according to the width of the material;

[0018] (2) Place a set of materials in front of the photoelectric sensor assembly located at the end;

[0019] (3) The photoelectric sensor receives the signal and transmits it to the powertrain, causing the powertrain to drive the conveyor roller to rotate;

[0020] (4) The material comes into contact with the trigger roller under the drive of several conveyor rollers. The trigger roller drives the trigger mechanism to press the trigger switch so that the power assembly of one set of single motor parallel stacking roller conveyors stops working.

[0021] (5) Place another set of materials in front of the photoelectric sensor assembly of another set of single-motor parallel stacking roller conveyors;

[0022] (6) Another group of materials comes into contact with the trigger roller under the drive of several conveyor rollers. The trigger roller drives the trigger mechanism to press the trigger switch. At this time, both trigger switches are closed, and the two power assemblies on the two single motor stacking roller conveyors start to work. At this time, the two groups of materials are aligned and the conveyor is started.

[0023] (7) Two groups of materials simultaneously enter the gap between the two photoelectric sensor assemblies;

[0024] (8) When the two groups of materials leave the range of the photoelectric sensor assembly, the powertrain stops working;

[0025] (9) Repeat steps (2) to (8) until there is material in each interval, and complete the stacking of materials;

[0026] (10) The elevator transports the roller conveyor and the materials on the roller conveyor to the unloading point. The power unit drives all the conveyor rollers to rotate and send all the materials out of the roller conveyor.

[0027] In summary, the beneficial effects of this invention are:

[0028] 1. The single-motor parallel stacking roller conveyor only requires adjustment and maintenance of one power unit, making it easy to operate and solving the need to transport large-tonnage materials in narrow spaces within elevators.

[0029] 2. Reduces equipment maintenance time and costs, greatly improves material flow efficiency, and reduces usage costs and maintenance time.

[0030] 3. Multiple fixing holes allow the support frame to be adjusted in position, thus enabling the use of goods of different widths.

[0031] 4. The position of the support rod can be further fine-tuned using the movable groove.

[0032] 5. The alignment mechanism enables the materials on the two sets of roller conveyors to be aligned with each other.

[0049] like Figure 1-5 As shown, a single-motor parallel stacking roller conveyor includes a frame 1 and several conveyor rollers 2. The several conveyor rollers 2 are rotatably connected to the frame 1, and adjacent conveyor rollers 2 are mutually connected through transmission. The frame 1 is provided with a power assembly 3, and the output shaft of the power assembly 3 is connected through transmission to one of the conveyor rollers 2. The frame 1 is provided with several photoelectric sensor assemblies 4, and there is a gap 5 between the several photoelectric sensor assemblies 4. One of the photoelectric sensor assemblies 4 is located at the end of the frame 1, and there is also a gap 5 between the other end of the frame 1 and the last photoelectric sensor assembly 4. The length of each gap 5 is equal.

[0050] By adopting the above technical solution and utilizing multiple photoelectric sensor assemblies 4, materials can be continuously placed in front of the first photoelectric sensor assembly 4, causing the power assembly 3 to continuously drive all materials forward, thereby completing the stacking. The single-motor stacking roller conveyor only requires adjustment and maintenance of one set of power assemblies 3, making operation simple and solving the need to transport large-tonnage materials in narrow spaces of elevators.

[0051] Each conveyor roller 2 is equipped with a sprocket 6 at one end, and adjacent conveyor rollers 2 are connected to each other by a chain 7. The transmission connection between the conveyor rollers 2 is achieved by the meshing of the chain 7 and the sprocket 6.

[0052] The photoelectric sensor assembly 4 includes a support frame 8, a support rod 9, and a mounting bracket 10. The support frame 8 is fixedly connected to the frame 1, the support rod 9 is detachably connected to the support frame 8, and the mounting bracket 10 is connected to the support rod 9. The support frame 8, support rod 9, and mounting bracket 10 are used to fix and support the photoelectric sensor.

[0053] The support frame 8 has a movable slot 11, through which the support rod 9 passes. The support rod 9 is threadedly connected to two clamping nuts 12, which are respectively mounted on both sides of the support frame 8. By tightening or loosening one of the clamping nuts 12, the support rod 9 can be fixed or released, thereby adjusting its position to change the size of the gap 5 to accommodate the width of the goods.

[0054] The mounting bracket 10 has a mounting hole through which the support rod 9 passes. The mounting bracket 10 also has a deformation groove 13 that communicates with the mounting hole. A clamping bolt 14 is threaded through the mounting bracket 10. Tightening the clamping bolt 14 causes the mounting bracket 10 to deform at the deformation groove 13, thereby tightening the mounting hole and clamping the support rod 9, thus establishing a connection between the mounting bracket 10 and the support rod 9. Simultaneously, the cooperation between the support rod 9 and the mounting hole allows the mounting bracket 10 and the support rod 9 to rotate, thereby adjusting the orientation of the photoelectric sensor.

[0055] The support frame 8 has a first fixing hole, and the frame 1 has several second fixing holes 16. The support frame 8 is equipped with a fixing bolt 15 and a fixing nut. The fixing bolt 15 passes through the first fixing hole and one of the second fixing holes 16, and the fixing nut is threaded to the fixing bolt 15, pressing the fixing nut onto the frame 1. The multiple second fixing holes 16 allow the support frame 8 to be adjusted in position, thus accommodating goods of different widths.

[0056] A retaining ring 17 is provided at one end of the conveyor roller 2 near the frame 1. The retaining ring 17 prevents the material from rubbing against the frame 1.

[0057] Between each conveyor roller 2 equipped with a retaining ring 17, there are several conveyor rollers 2 without retaining rings 17. By configuring the retaining rings 17 in this way, the number of retaining rings 17 used can be reduced, thereby reducing costs.

[0058] The single-motor parallel stacking roller conveyor is configured in two sets, symmetrically arranged. By symmetrically arranging two sets of single-motor parallel stacking roller conveyors, the volume of material that the roller conveyor can accommodate can be increased.

[0059] Both sets of single-motor parallel stacking roller conveyors are equipped with alignment mechanisms. The alignment mechanism includes a trigger roller, a triggering mechanism, and a trigger switch 26. The trigger rollers on both sets of single-motor parallel stacking roller conveyors are on the same straight line. Each trigger roller includes a rotating shaft 18, a contact tube 19, several support pins 20, and several elastic elements 21. The rotating shaft 18 is rotatably connected to the frame 1 and is drively connected to the conveyor roller 2. The contact tube 19 is sleeved on the outside of the rotating shaft 18, and a movable gap is formed between the contact tube 19 and the rotating shaft 18 through the support pins 20. Each support pin 20 is connected to the rotating shaft 18. The shaft 18 is slidably connected, and several elastic elements 21 are respectively arranged between each support pin 20 and the rotating shaft 18. The triggering mechanism includes a roller 22, a slide 23, a base 24 and an elastic element 25. The base 24 is fixedly connected to the frame 1, the slide 23 is slidably connected to the base 24, the elastic element 25 is arranged between the base 24 and the slide 23, the roller 22 is rotatably connected to the slide 23, the roller 22 abuts against the contact tube 19, and the trigger switch 26 is arranged between the slide 23 and the base 24, and the trigger switch 26 abuts against the slide 23. The alignment mechanism enables the materials on the two sets of roller conveyors to be aligned with each other. Specifically, the material is placed on one of the roller conveyors. When the material moves to the trigger roller, the contact tube 19 will push the support pin 20 downward under the pressure of the material, overcoming the elastic force of the elastic element 21. When it moves downward, it will push the slide 23 through the roller 22 to slide against the elastic force of the elastic element 25, so that the slide 23 presses the trigger switch 26. At this time, the power assembly 3 on the roller conveyor will stop working. When the material on the other roller conveyor also presses the trigger roller, the two trigger switches 26 will close at the same time. Through this condition, the power assemblies 3 on the two roller conveyors will be in working state at the same time. At this time, the two sets of materials can be aligned with each other and transported synchronously.

[0060] A method for stacking roller conveyors includes the following steps:

[0061] (1) Adjust the spacing of each photoelectric sensor assembly 4 according to the width of the material;

[0062] (2) Place a set of materials in front of the photoelectric sensor assembly 4 located at the end;

[0063] (3) The photoelectric sensor receives the signal and transmits it to the powertrain 3, causing the powertrain 3 to drive the conveyor roller 2 to rotate;

[0064] (4) The material comes into contact with the trigger roller under the drive of several conveyor rollers 2. The trigger roller drives the trigger mechanism to press the trigger switch 26 so that the power assembly 3 of one set of single motor stacking roller conveyors stops working.

[0065] (5) Place another set of materials in front of the photoelectric sensor assembly 4 of another set of single-motor parallel stacking roller conveyors;

[0066] (6) Another group of materials comes into contact with the trigger roller under the drive of several conveyor rollers 2. The trigger roller drives the trigger mechanism to press the trigger switch 26. At this time, both trigger switches 26 are closed, and the two power assemblies 3 on the two sets of single motor stacking roller conveyors start to work. At this time, the two sets of materials are aligned and the conveying begins.

[0067] (7) The two groups of materials simultaneously enter the gap 5 between the two photoelectric sensor assemblies 4;

[0068] (8) When the two groups of materials leave the range of the photoelectric sensor assembly 4, the power assembly 3 stops working;

[0069] (9) Repeat steps (2) to (8) until there is material in each interval 5, and complete the stacking of materials;

[0070] (10) The elevator transports the roller conveyor and the materials on the roller conveyor to the unloading point. The power unit 3 drives all the conveyor rollers 2 to rotate and send all the materials out of the roller conveyor.

[0071] It should be noted that many specific details have been set forth in the above description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.
