Description

TECHNICAL FIELD

[0001] The utility model belongs to the field technology of nickel sulfate packaging line equipment, specifically relates to a kind of tray conveying system under narrow space of nickel sulfate packaging line. BACKGROUND

[0002] In the production and packaging process of nickel sulfate, the conveying of the tray is one of the key links. In the conventional production scene, many tray conveying systems are used in cooperation with the unstacker to complete the entire tray conveying process. However, some scenes are limited by the space position and cannot install the unstacker. In this case, enterprises usually use manual tray placement to replace the unstacker to complete the placement and conveying of the tray. The traditional manual tray placement method is to place the tray manually on the stacking station by the worker after the robot stacking is completed and the stack tray is conveyed out for the next round of stacking operation. However, this traditional manual tray placement method has obvious disadvantages: first, the safety risk is high. When the worker places the tray near the stacking station, a collision may occur between the worker and the robot or other automated equipment that is running, resulting in personal injury. Second, the placement position is not fixed, which affects the subsequent stacking effect and reduces the overall production efficiency and stability. SUMMARY

[0003] The utility model aims to provide a kind of tray conveying system under narrow space of nickel sulfate packaging line, to solve the problem of the above background technology that narrow space cannot install unstacker, manual tray placement has safety risk and placement position stability is insufficient.

[0004] To achieve the above purpose, the technical scheme of the utility model is as follows: A kind of tray conveying system under narrow space of nickel sulfate packaging line, including conveying platform, the conveying platform includes several conveying rollers and rack, the several conveying rollers are arranged in parallel on rack, the conveying platform bottom is provided with driving device, and the side of conveying platform is provided with positioning device, the conveying platform is sequentially and circularly connected and is provided with multiple, wherein the end conveying platform is provided with buffer device.

[0005] Further, the driving device includes a driven sprocket connected to one end of the conveying roller, the driven sprocket is connected with a driving sprocket, and a chain is arranged between the two. The driving sprocket is connected with a speed reducer, and the speed reducer is connected with a motor.

[0006] Further, the positioning device includes a positioning cylinder arranged on the rack, and the positioning cylinder is connected with a positioning block. The positioning device also includes a positioning sensor arranged on the side of the conveying platform, and the positioning sensor is connected with a PLC.

[0007] Furthermore, the buffer device includes a buffer cylinder disposed at one end of the frame, and the buffer cylinder is connected to a buffer block.

[0008] Furthermore, a foot pedal is provided at the bottom of the frame, and a button is provided at one end of the frame.

[0009] The beneficial effects of this utility model are as follows: The conveying platform is equipped with continuously and compactly arranged conveying rollers to form empty pallet placement stations, palletizing stations, and pallet output stations. The physical distance between each station is minimized to adapt to the layout of narrow spaces. The drive device drives the conveying rollers to rotate through precisely controlled driving force to achieve pallet positioning and conveying. The positioning device can sense the lateral and longitudinal position deviation of the pallet in the narrow space in real time and provide instant and precise correction feedback through pneumatic or electric actuators to ensure that the pallet is always in the optimal palletizing position in the limited space. The buffer device assembly can reduce the impact force of the pallet during extremely close-range or high-speed conveying and prevent it from causing accidental collisions to surrounding equipment or structures. Foot pedals and buttons enable operators to perform semi-automatic operation and improve the flexible human-machine collaboration capability according to production needs.

[0012] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figs. 1-2 As shown, a pallet conveying system for a nickel sulfate packaging line in a confined space includes a conveying platform 1. The conveying platform 1 includes several conveying rollers 2 and a frame 3. The several conveying rollers 2 are arranged in parallel on the frame 3. A driving device is provided at the bottom of the conveying platform 1, and a positioning device is provided on the side of the conveying platform 1. Multiple conveying platforms 1 are arranged sequentially end to end, and a buffer device is provided at the end of the conveying platform 1.

[0014] Specifically, the drive device includes a driven sprocket 8 connected to one end of the conveyor roller 2, a drive sprocket 6 connected to the driven sprocket 8, a chain 7 between the two, a reducer 5 connected to the drive sprocket 6, and a motor 4 connected to the reducer 5.

[0015] Specifically, the positioning device comprises a positioning cylinder 9 arranged on the frame 3, the positioning cylinder 9 being connected with a positioning block 10, and further comprises a positioning sensor 11 arranged on the side of the conveying platform, the positioning sensor 11 being connected with a PLC.

[0016] Specifically, the buffering device comprises a buffering cylinder 12 arranged at one end of the frame 3, the buffering cylinder 12 being connected with a buffering block 13.

[0017] Specifically, the frame 3 is provided with a foot pedal 14 at the bottom, and is provided with a button 15 at one end.

[0018] Embodiment 1 In actual application, the conveying platform 1 comprises three workstations, i.e. an empty tray placing workstation, a stacking workstation and a stacked tray output workstation. Each workstation is composed of a plurality of parallel arranged conveying rollers 2. In the automatic mode, when the stacked tray has been output from the stacking workstation, and the positioning sensor 11 detects that the empty tray placing workstation has a tray to be conveyed, and the stacking workstation is also ready, a detection signal is transmitted to the PLC, the driving device is started, the output shaft of the motor 4 is connected with the input shaft of the speed reducer 5, further driving the driving sprocket 6 and the driven sprocket 8, and then driving the conveying rollers 2 of the empty tray placing workstation to convey the tray to the stacking workstation. The retractable positioning sensor 11 is used to detect the longitudinal and transverse offset of the tray in real time, and sends a signal to the positioning cylinder 9 to drive the positioning block 10 to make fine adjustment, so as to ensure the optimal stacking position of the tray in the narrow space. After the positioning block 10 accurately positions the tray at the specified position, the next round of stacking operation can be prepared.

[0019] The buffering cylinder 12 plays a protective role on the tray in this process, preventing external objects from impacting and interfering. When the tray contacts the buffering block 13, the buffering cylinder 12 acts to slow down the impact force of the tray and protect the tray. In particular, the buffering block 13 is made of flexible material or energy-absorbing structure, and the deceleration curve of the buffering cylinder 12 is optimized in design when the tray contacts the buffering block 13, so as to minimize the disturbance to the nickel sulfate product in the tray and ensure the long-term stable operation of the equipment.

[0020] Embodiment 2 Further, the embodiment is basically the same as embodiment 1, like Figs. 1-2As shown, the difference lies in that the foot pedal 14 and the button 15 are added in the embodiment, and in the embodiment, it belongs to a semi-automatic mode, allowing the operator to intervene through the foot pedal 14 and the button 15, and the PLC can receive and respond to the control signal issued by the operator to convey the tray from the empty tray placing station to the stacking station or from the stacking station to the pallet conveying station at a preset, controlled speed and path, thereby providing high flexibility and man-machine cooperation capability for the start-up, debugging, abnormal handling or specific production requirements of the production line.
