Description

Technical Field

[0001] This utility model relates to the field of conveyor technology, specifically a double-stack grouping pitch conveyor. Background Technology

[0002] In the traditional model, goods output from the end of the pallet conveyor line are mostly transported individually. However, for full truckload loading, goods need to be arranged side by side at a preset interval to maximize the use of the transport vehicle's loading space and increase the single transport volume. To achieve this, existing systems require at least one double-pallet marshalling machine and one rail-mounted mobile vehicle (mobile double-pallet conveyor). The pre-loading preparation work is completed through a two-step operation: "the double-pallet marshalling machine marshals individual goods in parallel" and "the rail-mounted mobile vehicle receives the marshalled double pallet goods and transfers them to the loading interface." However, the tandem use of the two devices increases equipment procurement costs and site space occupation, and also extends the goods transfer path, resulting in an increase in the total time spent on marshalling and transfer.

[0003] Therefore, this utility model provides a double-stack grouping pitch conveyor. Utility Model Content

[0004] To address the inherent drawbacks of the traditional two-step operation mode of "double stack marshalling machine + rail-mounted vehicle" for parallel transport of two goods, which results in high procurement costs, large site space, and long transfer paths, leading to low overall loading and preparation efficiency, this utility model aims to provide a double stack marshalling pitch conveyor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a double-stack grouping and tilting conveyor, comprising a frame, wherein a feeding mechanism is provided on the upper part of the frame, capable of synchronously and side-by-side conveying two goods to the next production process, the feeding mechanism comprising: The conveying assembly includes two sets of roller conveyors set on the upper part of the frame, two sets of chain conveyors that work in conjunction with the roller conveyors on the upper part of the frame, four symmetrically distributed rotating shafts rotatably mounted on the upper part of the frame, cams fixedly mounted at both ends of the four rotating shafts, the bottom supports of multiple chain conveyors contacting the outer contour of the cams, and a drive assembly for driving the rotating shafts is provided in the middle of the frame. A tilting assembly, located on the upper side of the frame, is used to adjust the angle of the end of the equipment.

[0006] Preferably, the flipping assembly includes a flipping frame rotatably mounted on one side of the upper part of the frame. Two sets of roller conveyors are also provided on the upper part of the flipping frame. A transmission rod is fixedly installed on the middle of both sides of the roller conveyor. Hydraulic cylinders are rotatably mounted on both sides of the upper part of the frame. The drive ends of the two hydraulic cylinders are movably mounted on one end of the transmission rod.

[0007] Preferably, the drive assembly includes two lifting gear motors fixedly installed in the middle of the frame, and both lifting gear motors are connected to the rotating shaft via a chain-sprocket transmission.

[0008] Preferably, a roller limiter is provided on the upper left side of the frame to limit the goods located on the left roller conveyor.

[0009] Preferably, a chain limiter is provided on the upper right side of the frame, which is used to limit the goods conveyed to the right side by the chain conveyor.

[0010] Preferably, both the roller conveyor and the chain conveyor are driven and controlled by a geared motor in the power box. The roller conveyor is used for longitudinal conveying, and the chain conveyor is used for transverse conveying.

[0011] Beneficial effects This invention provides a double-stack grouping pitch conveyor. Compared with the prior art, it has the following advantages: 1. This application utilizes a roller conveyor for longitudinal positioning, followed by a lifting chain conveyor for lateral transfer and grouping. During operation, the first item is conveyed and positioned by the roller conveyor, then transferred to the chain conveyor by a cam lifting mechanism and laterally transported to a temporary storage position. When the second item completes the same process, the two chain conveyors synchronously descend and reset, placing the two items side by side on the same plane. Finally, the roller conveyor synchronously transports the grouped double stack of goods to the next process. The entire process is automatically completed through photoelectric sensing and program control, achieving highly efficient automated grouping of heavy-load goods from serial to parallel operation, thus improving the logistics efficiency and space utilization of the production line.

[0012] 2. This application uses a hydraulic cylinder to drive a transmission rod, which in turn drives the end tilting frame to adjust its pitch angle. When the interface height or position of the next process (such as loading) changes, there is no need to move the entire equipment or adjust the production line layout. Only the hydraulic cylinder needs to be controlled to raise or lower the roller conveyor at the outlet end, thereby matching the inlet position of the next process. This flexible pitch adjustment capability effectively solves the inconvenience problem between fixed conveyors and mobile receiving equipment, providing crucial concession space for the production line.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-7 This utility model provides a technical solution: a double-stack grouping tilting conveyor, including a frame 1, with a feeding mechanism 2 on the upper part of the frame 1, capable of synchronously and side-by-side conveying two goods to the next production process. The feeding mechanism 2 includes: The conveying assembly 21 includes two sets of roller conveyors 211 disposed on the upper part of the frame 1. The two sets of roller conveyors 211 are respectively located on the upper sides of the frame 1. The goods enter first from the left side of the roller conveyor 211, and then the photoelectric sensor (model LS64 / 2SE-L) is activated.2. This is a photoelectric sensing technology with separate transmitter and receiver. Through the "through-beam" cooperation of the transmitter and receiver, it detects whether an object is blocking the light path. Its core function is for accurate non-contact object recognition. Once detected, the geared motor in the power unit starts. The appropriate geared motor is selected based on the weight of the goods and the running speed. Heavy-load goods are transported on roller conveyor 211 until they are detected by the first diffuse reflection photoelectric sensor (model G18-3B2PB). This diffuse reflection photoelectric sensor is a photoelectric sensing technology that works based on the principle of diffuse reflection of light. Its core is integrating a transmitter (emitting infrared or visible light) and a receiver into the same device, achieving non-contact sensing by detecting the diffuse reflection of light from the object's surface. Upon arrival, the geared motor inside the power box begins to decelerate and is detected by the second diffuse reflection photoelectric sensor (same as the first diffuse reflection photoelectric sensor). The geared motor inside the power box then stops operating. At this time, the goods reach the left roller limit 212. The upper part of the frame 1 is equipped with two sets of chain conveyors 213 that work in conjunction with the roller conveyor 211. Then, the first and second lifting geared motors 214 start synchronously. The lifting geared motors 214 need to be selected based on the weight of the goods, the lifting height, and the lifting speed. Power is transmitted to the rotating shafts 215 via chain drive. The upper part of the frame 1 is equipped with four symmetrically distributed rotating shafts 215, with two shafts on each of the left and right sides. Driven by a lifting gear motor 214, cams 216 are fixedly installed at both ends of four rotating shafts 215. The bottom supports of multiple chain conveyors 213 are in contact with the outer contour of the cams 216. A drive assembly for driving the rotating shafts 215 is provided in the middle of the frame 1, causing the rotating shafts 215 to rotate, driving the cams 216 to rotate 180°. The lifting of the chain conveyors 213 causes the goods to fall off the roller conveyor 211. At this time, the gear motors of two chain conveyors 213 start simultaneously to transport the heavy-load goods until the heavy-load goods reach the diffuse reflection photoelectric point of the second chain conveyor 213. At this time, the gear motor of the first chain conveyor 213 stops first, and the first lifting gear motor... When machine 214 starts, cam 216 rotates 180°, and the left chain conveyor 213 returns to its low position (initial position). Meanwhile, the reduction motor of the second chain conveyor 213 slows down to a stop, and the heavy-loaded goods stop at the chain limit 217. Once the second heavy-loaded goods arrive, they undergo the same conveying process as the first, aligning them side-by-side. At this point, both lifting reduction motors 214 start simultaneously, resetting the chain conveyor 213. Then, both lifting reduction motors 214 stop simultaneously, while the reduction motor of roller conveyor 211 starts, simultaneously conveying the two parallel heavy-loaded goods to the next process step. The flipping component 22 is located on the upper side of the frame 1 and is used to adjust the angle of the end of the equipment.

[0023] The tilting assembly 22 includes a tilting frame 221 rotatably mounted on one side of the upper part of the frame 1. Two sets of roller conveyors 211 are also provided on the upper part of the tilting frame 221. A transmission rod 223 is fixedly installed on the middle of both sides of the roller conveyor 211. Hydraulic cylinders 222 are rotatably mounted on both sides of the upper part of the frame 1. The driving ends of the two hydraulic cylinders 222 are movably mounted on one end of the transmission rod 223. When the inlet position of the next loading process needs to be adjusted, the hydraulic cylinders 222 are driven, and under the transmission of the transmission rod 223, the tilting frame 221 can rotate around the hinge point with the frame 1 to achieve the adjustment of the pitch angle.

[0024] The drive assembly includes two lifting gear motors 214 fixedly installed in the middle of the frame 1. Both lifting gear motors 214 are connected to the rotating shafts 215 via chain-sprocket transmission. Each pair of rotating shafts 215 is driven by two chains-sprockets at the drive end of one lifting gear motor 214, which transmits torque to the rotating shafts 215. When each pair of rotating shafts 215 are connected to the driven sprocket, one is a key connection and the other is a shrink sleeve connection. This avoids the problem of the chain conveyor 213 not being level when both are key connections.

[0025] A roller limiter 212 is provided on the upper left side of the frame 1 to limit the goods located on the left roller conveyor 211.

[0026] A chain limiter 217 is provided on the upper right side of the frame 1. The chain limiter 217 is used to limit the goods conveyed to the right side by the chain conveyor 213. The chain limiter 217 is composed of a baffle and bolts. By rotating the bolts, the position of the baffle is adjusted, thereby limiting the goods that have moved to the side of the chain conveyor 213.

[0027] Both the roller conveyor 211 and the chain conveyor 213 are driven and controlled by a geared motor in the power box. The roller conveyor 211 is used for longitudinal conveying, and goods can be transported by the roller conveyor 211. The chain conveyor 213 is used for transverse conveying, and the chain conveyor 213 can transport two goods simultaneously by transverse transport, and then use the roller conveyor 211 to transport them again.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] During operation, a single heavy-load cargo enters the left roller conveyor 211 from the left side of the frame 1. After the photoelectric sensor detects the cargo, the geared motor in the power box starts and drives the roller conveyor 211 to transport the cargo. When the cargo is detected by the first diffuse reflection photoelectric sensor, the geared motor starts to decelerate. When it reaches the second diffuse reflection photoelectric sensor, the geared motor stops, and the cargo completes the initial positioning at the roller limit 212. At this time, the two lifting reduction motors 214 start synchronously, driving the four symmetrically distributed rotating shafts 215 to rotate through chain-sprocket transmission, and the cams 216 at both ends of the rotating shafts 215 rotate 180° accordingly.

[0030] Cam 216 lifts the bottom support of chain conveyor 213, causing chain conveyor 213 to rise. Goods detach from roller conveyor 211 and fall onto chain conveyor 213. The geared motor of chain conveyor 213 starts, laterally conveying the goods to the right. When the goods reach the diffuse reflection photoelectric point of the right (second) chain conveyor 213, the geared motor of the first chain conveyor 213 stops, and its corresponding lifting geared motor 214 starts in reverse. Cam 216 resets, and the left (first) chain conveyor 213 returns to its low position. The second chain conveyor 213 decelerates its motor to a stop, and the goods are temporarily stored at the chain limit 217. At this time, the second heavy-load goods repeat the above "longitudinal conveying - lateral shifting" steps until they are attached to and aligned with the first temporarily stored goods, completing the double stack grouping. The two lifting deceleration motors 214 start synchronously again, the chain conveyor 213 resets to the low position, and the lifting deceleration motor 214 stops running. When the deceleration motor of the roller conveyor 211 restarts, the two parallel goods are synchronously longitudinally conveyed to the next production process. When the angle of the loading inlet position needs to be adjusted in the current process, the hydraulic cylinders 222 on both sides of the frame 1 are activated, and the tilting frame 221 is driven to rotate around the hinge point with the frame 1 through the transmission rod 223 (two sets of roller conveyors 211 are also provided on the upper part of the tilting frame 221), so as to realize the pitch angle adjustment and provide room for the loading inlet position.
