Description

Technical Field

[0001] This utility model relates to a workbench, specifically to an intelligent warehouse dual-channel roller conveyor workbench. Background Technology

[0002] There are some problems with existing warehousing and logistics equipment:

[0003] The conflict between space and efficiency: Traditional single-channel conveyor lines only support single-person, single-side operation, which is inefficient (such as the fixed operating table in patent CN202222192289.4), and the reversal depends on manual intervention, which leads to process interruption.

[0004] Lack of queuing control: The turnover boxes are prone to accumulation and blockage during circulation (compared to the conveying system of patent CN202310391748.8), lacking a dynamic segmented blocking mechanism, and unable to achieve continuous operation.

[0005] The paths for empty container replenishment and full container transfer intersect (refer to the storage equipment in patent CN202110128765.X), requiring frequent avoidance and increasing operational complexity.

[0006] Poor stopping stability: Traditional conveyor lines rely solely on physical baffles at the end for interception, resulting in high impact force on the turnover boxes, which can easily damage the boxes or equipment.

[0007] Existing equipment struggles to simultaneously achieve efficient material feeding, automatic reversing, dynamic diversion, and path optimization, resulting in low warehouse turnover efficiency. Utility Model Content

[0008] To address the problems in the existing technology, this utility model provides an intelligent dual-channel roller conveyor worktable for warehousing.

[0009] This utility model provides the following technical solution:

[0010] A smart warehouse dual-channel roller conveyor workbench includes an L-shaped frame divided into upper and lower roller lines. A dual-channel roller conveyor line is installed on the L-shaped frame, comprising a first roller conveyor working area and a second roller conveyor working area. A workbench and a display mounting column are installed at the front end of the dual-channel roller conveyor line. The workbench is used to temporarily place turnover boxes. A first display and a second display are installed on the display mounting column. An electric stopper for the middle box and a turning mechanism for the middle box are installed in the second roller conveyor working area. A lifting conveyor transformation module is installed in the first roller conveyor working area. An electric stopper for the box and a hydraulic buffer are installed on the left side of the L-shaped frame. A tail baffle and an empty box ejection mechanism are installed at the left rear end of the L-shaped frame.

[0012] Furthermore, the lifting and conveying transformation module includes two support plates on both sides of the conveying transmission, a conveying tank chain, linear bearings, two synchronous shafts on both sides, and a drive motor. The drive motor drives the two synchronous shafts on both sides through a reducer. A first sprocket and a second sprocket are installed on the two synchronous shafts. The two synchronous shafts are installed inside the two support plates on both sides of the conveying transmission. The conveying tank chain is set inside the two support plates on both sides of the conveying transmission, and the conveying tank chain is sleeved on the sprockets of the two synchronous shafts.

[0013] Furthermore, the reducer is fixed to the bottom surface of the profile by a reduction mounting bracket, the synchronous shafts on both sides are mounted on bearing seats, a profile base frame is set around the bottom surface of the profile, and a central fixed bracket for the conveying module is set in the middle of the bottom surface of the profile.

[0014] Furthermore, a linear bearing and a bearing fixing plate are installed on the profile base frame. The linear bearing passes through the lifting guide shaft, and a conveying module fixing plate is installed on the bearing fixing plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Dual-station collaboration: Through the L-shaped frame and dual-channel design, it supports two people to feed materials at the same time, improving the throughput per unit time.

The second roller conveyor working area 6 is equipped with a middle box electric stopper 7 and a turning middle box 9. The first roller conveyor working area 5 is equipped with a lifting conveyor transformation module 8. A box electric stopper 10 and a hydraulic buffer 11 are set on the left side of the L-shaped frame 19. A tail baffle 12 and an empty box ejection 13 are set at the left rear end of the L-shaped frame 19. The empty box ejection 13 is the placement position for the large vehicle robot.

[0028] An exit box detection sensor 16 is installed on the L-shaped frame 19 at the exit empty box 13. Two electric stoppers 14 are installed on the lower left side of the L-shaped frame 19, two stoppers 15 are installed on the lower right side of the L-shaped frame 19, and an electric control module 18 is also installed below the L-shaped frame 19.

[0029] The lifting conveyor transformation module includes two side support plates 24 for the conveyor drive, a conveyor tank chain 23, linear bearings 20, two side synchronous shafts 26, and a drive motor 28. The drive motor 28 drives the two side synchronous shafts 26 through a reducer 27. A first sprocket 33 and a second sprocket 29 are installed on the two side synchronous shafts 26. The two side synchronous shafts 26 are installed inside the two side support plates 24 for the conveyor drive. The conveyor tank chain 23 is arranged inside the two side support plates 24 for the conveyor drive and is sleeved on the sprockets of the two side synchronous shafts 26.

[0030] The reducer 27 is fixed on the bottom surface 17 of the profile by the reducer mounting bracket 32. The synchronous shafts 26 on both sides are mounted on the bearing seats 25. The bottom surface 17 of the profile is surrounded by the profile base frame 31. The middle fixed bracket 34 of the conveying module is set in the middle of the bottom surface 17. The linear bearing 20 and the bearing fixing plate 22 are installed on the profile base frame 31. The linear bearing 20 passes through the lifting guide shaft 21. The conveying module fixing plate 30 is installed on the bearing fixing plate 22.

[0031] Main features of this utility model:

[0032] 1. L-shaped frame layout:

[0033] A dual-channel roller conveyor line is installed on the right side, with customized workbenches and dual display stands on both sides, supporting simultaneous operation and information monitoring by two people. A lifting conveyor transformation module is installed at the corner for changing the direction of the turnover boxes.

[0034] 2. Lifting and Conveying Transformation Module:

[0035] After the lifting platform lifts the turnover box, the conveyor tank chain drives it to rotate 90° and transport it to the next section of the roller conveyor.

[0036] 3. Dynamic blocking system:

[0037] The stops are spaced along the roller line (with a spacing of 1.5 times the length of the turnover box). Each stop is equipped with a photoelectric sensor, which detects the position of the turnover box in real time and triggers the stop's lifting logic.

[0038] When the first turnover box is reversed, the rear stopper rises to intercept the second box; after the reversal is completed, the stopper descends and releases.

[0039] A pressure sensor is installed at the rear to detect the docking status of the turnover box and feed it back to the software system.

[0040] 4. Separate design for upper and lower roller conveyors:

[0041] Lower roller conveyor: Fully loaded containers are conveyed forward to the tail end for use by the large-scale robot.

[0042] Upper roller conveyor: Empty boxes are transported in reverse to a fixed station. Sensors at the end monitor the amount of empty boxes and control the timing of the trolley pushing the empty boxes.

[0043] 5. Tail buffer structure:

[0044] Tail baffle: This is the mounting bracket for the shock absorber. The tail baffle is made of polyurethane material to absorb impact energy. Shock absorber: It has a built-in damping structure that slows down and stops the turnover box, reducing the impact force by more than 60%.

[0045] 6. Control system:

[0046] Software system main control: Receives sensor signals and controls the action of the stopper and the operation of the lifting module.

[0047] Human-computer interaction: The dual-display bracket displays the real-time status of the process (such as "feedable" and "busy queue"), guiding the staff to operate at a faster pace.

[0048] Detailed workflow:

[0049] Step 1: Two workers simultaneously place turnover boxes on both sides of the L-shape, and the boxes are conveyed to the corner by roller conveyor.

[0050] Step 2: Automatic Reversing

[0051] The dual lifting mechanism lifts the box, and the conveyor chain turns and transports it to the vertical section. After the reversal is completed, a "ready to receive the next box" signal is sent.

[0052] Dual lifting mechanism refers to Figure 3 The two lifting conveying transformation modules are located on both sides of the fixed bracket 34 in the middle of the conveying module.

[0053] Step 3: Dynamic Queuing

[0054] If the first box has not completed its turn when the second box arrives, the second box will be blocked by the barrier, and the distance between them will automatically increase from 300mm to 600mm.

[0055] Step 4: Tail buffer positioning

[0056] The container contacts the hydraulic buffer (damping force adjustable from 200-500N), the baffle triggers the pressure sensor, and the software system confirms that it is in place before notifying the trolley to pick up the container.

[0057] Step 5: Empty container recirculation

[0058] The trolley pushes the empty container into the upper roller conveyor. When the second-to-last container in the temporary storage area triggers the sensor, the system stops pushing the container until the staff retrieves it.

[0059] Key parameters and selection criteria:

[0060] Roller line:

[0061] The roller has a diameter of 50mm, a wall thickness of 1.5mm, and is covered with a polyurethane anti-slip layer (coefficient of friction ≥0.6).

[0062] The motor has a power of 0.75kW, a reduction ratio of 1:30, and supports frequency conversion speed regulation (0.3-1.0m / s).

[0063] Hydraulic buffer:

[0064] Model: ACE MC25, stroke 25mm, maximum energy absorption 3.7J, suitable box weight ≤30kg;

[0065] Damping adjustment: Automatically adjusted based on pressure sensor feedback (e.g., a 30kg chamber corresponds to a damping force of 450N).

[0066] Advantages of this utility model:

[0067] 1. Dual-station collaboration: Through the L-shaped frame and dual-channel design, it supports two people to feed materials at the same time, improving the throughput per unit time.

[0068] 2. Automatic reversing: By using the lifting conveyor module in conjunction with the roller chain, the turnover box can be automatically turned 90°, eliminating manual intervention.

[0069] 3. Dynamic queuing control: Based on the collaboration of multi-level barriers and sensors, the turnover boxes are intercepted in segments to ensure continuous flow without blockage.

[0070] 4. Path separation: The upper and lower roller lines move in opposite directions, and the empty box replenishment and full-load flow paths are independent, reducing cross-interference.

[0071] 5. Buffering and Loss Reduction: The tail baffle is the mounting bracket for the buffer. The hydraulic buffer structure at the tail reduces the impact of the turnover box stopping and extends the service life of the equipment.
