Description

Technical Field

[0001] The present invention relates to the technical field of roller conveyors, and particularly to a stainless-steel roller conveyor and a method thereof. Background Art

[0002] Roller conveyors are applicable to various goods, such as intelligent packaging after agricultural product production, conveying lines far from laser cutting, and transportation of intelligent welding parts. The multi-section roller conveyor has the advantage that it can be controlled to open and close in single sections to prevent line blockage, and is favored by a large number of users. Due to different usage scenarios, the lengths of roller conveyors required by different users are also different. Currently, manufacturers disassemble the roller conveyor into multiple roller conveying units, and users can choose to purchase an appropriate number of roller conveying units according to the required length and splice them by themselves.

[0003] After retrieval, although the roller conveyors in the prior art have the function of individually controlling opening and closing, during the actual conveying process, it is still necessary to allocate manpower to observe the density of goods on the line for conveying adjustment. This not only causes waste of labor, but also cannot achieve seamless docking of feeding, reducing the conveying efficiency. Therefore, we propose a new type of stainless-steel roller conveyor and a conveying method. Summary of the Invention

[0009] Preferably, on the lower surfaces of Rack 1 and Rack 2, a support frame 1 is fixed. And below the incoming material rack, a support frame 2 for fixing the front side plate and the rear side plate is arranged. The heights of the support frame 1 and the support frame 2 are adjustable.

[0010] Preferably, the tail guardrail includes a grooved baffle fixed to the ends of two connecting strips, and the bottom of the groove of the grooved baffle faces the second roller. The bottom of the groove of the grooved baffle is embedded with sliding bearings near both ends, and the two sliding bearings are slidably connected with guide round rods. The two guide round rods are fixed with the same strip support plate at one end close to the second roller. The strip support plate is located above the conveying plane as a whole, and a compression spring is fixed on the side of the middle of the strip support plate close to the grooved baffle, and a circular hole is opened in the middle of the grooved baffle for the compression spring to pass through.

[0014] A stainless steel roller conveying method comprises the following steps:

[0015] S1: First, the material runs to the end position via the original roller. When the material reaches the photoelectric position 1, roller 1 is started and begins to carry the material. When the material reaches the photoelectric position 2, roller 2 begins to carry the material and continues to run. When the material leaves the photoelectric position 2, roller 1 stops. When the material reaches the photoelectric position 3, that is, the tailgate, roller 2 stops.

[0016] At the same time, when photoelectric 3 detects the presence of material, roller conveyor 2 cannot be started by photoelectric 2. When photoelectric 3 detects the presence of material and material reaches photoelectric 2, roller conveyor 1 stops running. When the material at the position irradiated by photoelectric 3 is transported away, all lines resume operation.

[0017] S2: When the material reaches the photoelectric position 3, it will hit the extended strip plate, which will drive the connected contact head and electrical contact piece to separate, and then cut off the power to the reduction motor driving the roller table 2;

[0018] S3: When the original roller conveyor receives materials, the drive motor in the anti-wear mechanism is started. At this time, under a series of transmissions such as the rack push-pull rod and the driven gear, the two swing fences are allowed to swing alternately to guide the materials to run alternately from the two lines near the middle.

[0019] The beneficial effects of the present invention are:

[0020] 1. The three-stage conveying method is set up, and each stage is equipped with its own independent transmission mechanism, which makes it more convenient to control the material conveying spacing of the entire line. Combined with the sensing mechanism set at the end point of each transmission stage, the material can automatically and orderly advance at equal intervals. After the material finally reaches the tailgate and is taken out, the next material can quickly follow, thereby improving the overall conveying efficiency.

[0021] 2. Through the oil storage tank and oil-absorbing brush bristles, the roller can be intermittently stained with lubricating oil when it rotates, and then flow into the load-bearing bearing, playing the role of automatically lubricating the load-bearing bearing.

[0022] 3. By setting up the strip-shaped support plate and compression spring, when the conveyed material is about to reach the photoelectric third position, it can avoid the strong impact of inertia on the surface of the grooved baffle and cause collision to the material. This setting can play a certain buffering role.

[0023] 4. By setting up two swinging fences that can swing left and right, it is possible to prevent the material from always moving forward from a certain position during the conveying process, causing uneven wear of the roller and then easily causing deviation during the conveying process. This setting allows the material to move forward alternately from the middle position of the roller. Brief Description of the Drawings

[0050] A stainless steel roller conveying method comprises the following steps:

[0051] S1: First, the material runs towards the end position along the original roller path 12. When the material reaches the position of Photoelectric Sensor 1 - 10, Roller Path 1 - 9 is started and begins to carry the material. When the material reaches the position of Photoelectric Sensor 2 - 8, Roller Path 2 - 7 starts to carry the material and continue running. When the material leaves the position of Photoelectric Sensor 2 - 8, Roller Path 1 - 9 stops running. When the material reaches the position of Photoelectric Sensor 3 - 6, that is, at the tail gate 5, Roller Path 2 - 7 stops running.

[0052] Meanwhile, when Photoelectric Sensor 3 - 6 detects the presence of material, Roller Path 2 - 7 cannot be started by Photoelectric Sensor 2 - 8, that is, only one material can be ensured on Roller Path 2 - 7. When Photoelectric Sensor 3 - 6 detects the presence of material and a material reaches Photoelectric Sensor 2 - 8, Roller Path 1 - 9 stops running. When the material at the position irradiated by Photoelectric Sensor 3 - 6 is transported away, all lines resume operation.

[0053] S2: When the material reaches the position of Photoelectric Sensor 3 - 6, it will hit the protruding strip - shaped retaining plate 502 at this time, which will drive the separation of the connected contact head and electrical contact piece 508, and then cut off the power supply of the reduction motor 142 used to drive Roller Path 2 - 7.

[0054] S3: When the original roller path 12 receives the material, the drive motor 138 in the anti - wear mechanism 13 is started. At this time, under the drive of a series of transmissions such as the rack push - pull rod 1313 and the driven gear 133, the two swing gates 135 swing alternately to guide the material to run alternately along the two lines close to the middle, preventing continuous friction on a certain fixed position of the roller path and reducing the wear of the roller path.

[0055] The above - mentioned is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
