Abstract
Description
Technical Field
[0001] This invention belongs to the field of metal bar processing technology, specifically relating to a high-precision, lightweight conveying device and method. Background Technology
[0002] Currently, the trimming of metal raw material bars is done manually in a traditional manner. The worker places the trolley loaded with bars at the end of a 0.8-meter-high trimming machine, stands beside the machine head, and first uses their left hand to pass the bar through the spindle head and lock it in place. Then, they step on the switch with their left foot to start the spindle's high-speed rotation. Next, they hold the trimming machine's cutter slide with their right hand and push it towards the spindle head to cut the bar. After cutting, they release the foot switch, the spindle stops rotating, and then push the handle backward with their left hand to release the clamped bar. The trimmed bar is then pulled out, completing the trimming of one bar. In large-volume production, this repetitive process can easily lead to worker fatigue and increase the risk of production safety accidents. Furthermore, in large-volume production, efficiency cannot keep up with the production demands of downstream processes. Also, the dimensional accuracy of the trimmed bar heads produced by the worker is often large, affecting the precision of downstream processes. Additionally, the process requires a certain level of height and physical strength from the worker. Summary of the Invention
[0003] The purpose of this invention is to provide a high-precision, lightweight conveying device and method to solve the above-mentioned problems.
[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-precision, lightweight conveying device, including a transfer mechanism, wherein a feeding mechanism is installed on one side of the transfer mechanism, and a discharging mechanism is provided on the top of one side of the conveying mechanism for discharging materials.
[0005] The conveying mechanism includes a side frame that is fixedly connected to the transfer mechanism and the unloading mechanism. Both ends of the side frame are provided with conveying devices for orderly conveying the bars that roll off the unloading mechanism.
[0006] The conveying device includes two rotating shafts that are movably mounted on one side of the side frame. A timing belt is fitted on the outside of each rotating shaft, and a servo motor is connected to one end of one of the rotating shafts.
[0007] The synchronous belt has two air holes for sorting the rods. Two opposite air holes are provided on the protrusion between two adjacent air holes. Both sides of the air holes have arc-shaped grooves for adsorbing the rods.
[0008] Preferably, the conveying device has an arc-shaped groove inside, and the edge of the arc-shaped groove is slidably disposed on the side of the side frame, sliding on the side frame with the synchronous belt. The side of the side frame has a through groove with the same shape as the arc-shaped groove but larger in size, used to cover multiple connecting holes. The connecting holes are opened at the protrusion between each pair of adjacent air holes and are connected to multiple air holes. Air pumps are provided on both sides of the conveying mechanism, and the two air pumps correspond to the two conveying mechanisms respectively. The air inlet pipe of the air pump is connected to the arc-shaped groove, and the air outlet pipe is connected to the connecting holes.
[0009] Preferably, the transfer mechanism includes a base frame conveying mechanism, on which a plurality of electric cylinders are provided. An intermediate frame is mounted on the output shaft of the electric cylinders and drives the intermediate frame to move up and down. A movable frame is slidably provided on the intermediate frame. An electric push rod is provided between the movable frame and the intermediate frame to drive the movable frame to slide on the intermediate frame. The movable frame has a plurality of arc-shaped grooves II, and the diameter of the arc-shaped grooves II is larger than that of the air holes II.
[0010] Preferably, a plurality of rotating rollers are arranged between the tops of the conveying mechanism, and the plurality of rotating rollers are arranged to gradually tilt upward from the transfer mechanism toward the unloading mechanism.
[0011] Preferably, one end of each of the plurality of rotating rollers is connected to a through conveying mechanism via an extension shaft, and a synchronous belt is sleeved on the outer side of the plurality of extension shafts for synchronous movement, and a motor is driven to one of the extension shafts for the main power.
[0012] Preferably, each of the rotating rollers is provided with an air pipe at the end away from the extension shaft and passes through the air pipe to the other side of the conveying mechanism. An air pump is connected to the outside of the multiple air pipes. The rotating roller is cross-shaped and each protrusion has an arc-shaped top. Each arc has several air holes for discharging the gas that the air pump has filled into the air pipe and the interior of the rotating roller.
[0013] The specific steps for using a high-precision, lightweight conveying device are as follows:
[0014] S1. Unloading: The staff can place all the bars on the unloading mechanism and guide them to the conveying mechanism through the inclined guide of the unloading mechanism.
[0015] S2. Sorting: Using the conveying device on the conveying mechanism, multiple bars are conveyed in an orderly manner. During the conveying process, the bar can be initially positioned by the groove of the second air hole. The negative pressure is generated by the suction of the arc groove of the second air hole by the start of the first air pump to adsorb and fix the bar that falls into the second air hole. Then, the air blowing of the first air hole is used to prevent the bar from accumulating between the two second air holes. The whole process also utilizes the orderly entry of the bar into the second air hole.
[0016] S3. Stacking and sorting: The rotating rollers rotate in the direction of the bar towards the feeding mechanism. The lowest rotating roller is higher than the conveying device so as not to touch the highest point of the bar inside the air hole. The multiple air holes on the rotating rollers reduce hard contact with the bar during the rotation process to prevent the bar from stacking, thus reducing the noise generated during the operation.
[0017] S4. Transfer: The moving frame is moved by the electric cylinder and electric push rod and receives the bars conveyed by the conveying device from the top and bottom. The moving frame is located inside the two conveying devices.
[0018] The technical effects and advantages of this invention are as follows: By utilizing the second air hole, the bar can be initially positioned in a groove. The activation of the first air pump utilizes the arc-shaped groove on the second air hole to generate negative pressure, adsorbing and fixing the bar that falls into the second air hole. Then, air is blown through multiple first air holes to prevent the bar from accumulating between the two second air holes. Multiple air outlets on the rotating roller reduce hard contact with the bar during rotation, thus reducing noise during operation. An electric cylinder and electric push rod drive the moving frame to move and receive the bars conveyed by the conveying device. The moving frame is located inside the two conveying devices. The entire device represents a significant improvement in bar loading and automatic sorting, operating fully automatically. It also makes substantial progress in bar fixing, preventing bar accumulation, and reducing noise during operation. While maintaining the existing working environment, it achieves automated material handling, sorting, and stacking adjustment. Attached Figure Description

[0033] Specifically, the conveying device 202 has an arc-shaped groove 2026 inside, and the edge of the arc-shaped groove 2026 is slidably set on the side of the side frame 201. It slides on the side frame 201 with the synchronous belt 2022. The side of the side frame 201 has a through groove with the same shape as the arc-shaped groove 2026 but larger in size to cover multiple connecting holes 2025.
