[0002] At present, traditional steel bar conveying devices have gradually faded out of people's sight because of many limitations such as low mechanization degree and low production efficiency. Many traditional steel bar processing and conveying rely on manual handling and piecemeal processing, making the whole process relatively cumbersome and inefficient, time-consuming and laborious. Moreover, most steel bar conveying and processing on the market do not have a perfect integrated implementation method, and additional steel bar storage and classification are required. The steps are numerous and complex, which is not conducive to the automatic processing and operation of on-site steel bars. Content of the Utility Model

[0003] In order to overcome the deficiencies of the prior art, the technical problem to be solved by the utility model is to provide a device for transporting and storing steel bars, so as to solve the problems of consuming more manpower in steel bar transportation and low efficiency due to repeated operations for many times, realize high-efficiency automatic transportation of steel bars, and be able to store and classify them for easy access.

[0004] To achieve the above object, the utility model provides a device for transporting and storing steel bars, including: a steel bar straightening part, including a steel bar concentrator for steel bar aggregation, a spring driver installed in the steel bar concentrator and driving the steel bar to transport forward, and a straightener for correcting the steel bar; a transportation and cutting part, connected to the steel bar straightening part, including a conveyor belt for driving the corrected steel bar to move forward and a steel bar cutter for cutting the steel bar; a classification and storage part, connected to the transportation and cutting part, including a semi-circular feeder for receiving the cut steel bars, two storage tanks, and a classification moving rod. The classification moving rod acts to drop the steel bars of a specified length from the semi-circular feeder into different storage tanks for classification and storage.

[0005] Preferably, the straightener includes two vertically straightening rollers, two horizontally straightening rollers, and a motor driving the two vertically straightening rollers and the two horizontally straightening rollers to rotate in opposite directions. The motor drives the two vertically straightening rollers and the two horizontally straightening rollers to rotate to correct the steel bar from four dimensions.

[0006] Further, the steel bar concentrator is installed at one end of the workbench, and the two vertically straightening rollers and the two horizontally straightening rollers are installed at the other end of the workbench through two spaced support plates; the driving end of the spring driver is fixed in the steel bar concentrator, driving the spring to extend and contract, so that the concave slider moves linearly, driving the steel bar on the concave slider to transport forward.

[0007] Preferably, the steel bar cutter is installed on a crank - connecting rod mechanism, and the crank - connecting rod mechanism is installed on a rotating wheel disc. The reciprocating rotation of the rotating wheel disc drives the steel bar cutter to rotate and cut the steel bar.

[0008] Preferably, the classification moving rod is located between two storage slots. Vertical rods are installed on the outer sides of the two storage slots. The moving rod of the classification moving rod rotates under the drive of a servo motor and in cooperation with a transmission gear to form a closed system with the vertical rod, leaving only the other storage slot for storing steel bars.

[0009] Furthermore, a four - footed motor is fixed on the vertical rod of the semi - arc feeder. A semi - arc robotic arm is installed on the rotating shaft of the four - footed motor. The semi - arc robotic arm rotates to pour the cut steel bars into the storage slot.

During operation, the straightening wheels are driven by a motor to rotate simultaneously to correct the steel bar from four dimensions.

[0012] The transportation and cutting part is composed of a conveyor belt, a steel bar cutter and a ranging sensor. The steel bar enters the conveyor belt under the action of the straightener. The conveyor belt moves under the drive of a motor to drive the steel bar to move. When the extended length of the steel bar reaches the set value of the ranging sensor, the steel bar cutter quickly cuts the steel bar. The cut part is received by the classification and storage part.

[0013] The semi - arc feeder of the classification and storage part accepts the cut steel bars and periodically tilts towards the storage slot side to send the steel bars to the storage slot. The classification moving rod cooperates with the vertical rod to make the steel bars roll into the designated storage slot, realizing the classification and storage of steel bars of a specified length.

[0033] Next, refer to Figures 1 to 4 A detailed description will be given to the steel bar conveying and storing device of the present invention.

[0034] The steel bar conveying and storing device of the present invention is composed of a steel bar straightening part 200, a transportation and cutting part 100, and a classification and storage part 300 that are connected in sequence.

[0035] As Figure 2As shown in the figure, the transportation and cutting part 100 mainly consists of a base 101, a conveyor belt 102, a driving mechanism 103, a perforated plate 104, a rotating wheel disc 105, a crank - connecting rod mechanism 106, a steel bar cutter 107, and a ranging sensor 108. The base 101 is used to stably support the entire device. The conveyor belt 102 steadily conveys steel bars under the drive of the driving mechanisms 103 at both ends. The perforated plate 104 is located at one end of the conveyor belt 102 close to the steel bar cutter 107. A number of rollers are installed on both sides of the perforated plate 104, which are used to gather the steel bars on the conveyor belt 102 at the center and pass through the holes one by one under the action of thrust to achieve subsequent precise cutting. The rotating wheel disc 105 rotates reciprocally during operation, and cooperates with the crank - connecting rod mechanism 106 thereon to realize the rotary cutting of the steel bar cutter 107 thereon. The ranging sensor 108 obtains distance information through the reception and emission of laser signals, and is linked with the rotating wheel disc 105 to stop and cut the steel bar at a specified length.

[0036] As Figure 3As shown in the figure, the steel bar straightening part 200 mainly consists of a workbench 201, a steel bar concentrator 202, a spring driver 203, a concave slider 204, a reel 205, a support plate 206, a rotating shaft a207a, a rotating shaft b207b, a large runner a208a, a large runner b208b, a corner motor a209a, a corner motor b209b, a small corner motor a210a, a small corner motor b210b, a stepping motor a211a, a stepping motor b211b, a runner a212a, a runner b212b, and a single-hole steel plate 213. The workbench 201 is used to support and stabilize the entire mechanism, and other workpieces can be installed on it. The steel bar concentrator 202 is used for the aggregation of steel bars. The bundled steel bars are placed on the steel bar concentrator 202 for subsequent straightening treatment. The driving end of the spring driver 203 is fixed inside the steel bar concentrator 202 to drive the spring to extend and contract, so that the concave slider 204 moves linearly, indirectly driving the steel bar on the concave slider 204 to be transported forward. Two spaced support plates 206, large runners a208a, large runners b208b, rotating shafts a207a, rotating shafts b207b, corner motors, small corner motors, stepping motors, runners, and single-hole steel plate 213 constitute a straightener for correcting steel bars. Among them, the large runners a208a and large runners b208b are two vertical straightening runners with opposite rotation directions, driving the steel bar to be transported to the outlet and responsible for vertical straightening; the runners a212a and runners b212b are similar, responsible for horizontal straightening of the steel bar, and the runners a212a and runners b212b are two horizontal straightening runners.

The four feet of the four-foot motor are fixed on the vertical rod of the semi-circular feeder, and the semi-circular robotic arm on the rotating shaft of the four-foot motor is driven to rotate to pour the cut steel bars into the storage tank.

[0038] Next, with reference to Figures 1 to 4 and in combination with the description of the above structural features, the working principle of the device for conveying and storing steel bars of the present utility model will be described in detail:

[0039] 1. Assemble the device according to the above structure. Fix the bottom column of the steel bar concentrator 202 and the single-hole steel plate 213 to the bottom workbench 201 by welding. Select a steel column of appropriate length and weld it firmly. According to the height of the transportation cutting part 100, make it flush and point to the straightener, and make the outlet of the straightener and the round hole of the single-hole steel plate 213 coaxial. The driving end of the internal spring driver 203 is fixed to the inner wall of the steel bar concentrator 202 by screws. The spring is connected to the concave slider 204 to control its movement along the central axis. The protruding part of the steel bar concentrator 202 is placed between the large wheel a 208a and the large wheel b 208b. Support plates 206 are welded on both sides of the workbench 201, and the rotating shafts a 207a and b 207b are installed through them. When the corner motor works, the large wheels a 208a and b 208b on the rotating shafts start to rotate. Similarly, the stepping motors mounted on the inner side of the support plates 206 also rotate simultaneously to drive the rotation of the wheels a 212a and b 212b. The reel 205 is fixed to a suitable position on the workbench 201 with screws, and the rotation center line passes through the orifice of the straightener.

[0040] 3. The rotating shaft of the driving mechanism 103 is connected between the conveyor belts 102. When it rotates under drive, it drives the conveyor belts 102 to run. The conveyor belts 102 are concave long strip chains that can accommodate cylindrical steel bars, facilitating the transportation of steel bars. The perforated plate 104 is fixed at the outlet of the conveyor belts 102, with a roller group having a 45-degree inclination on both sides, causing the steel bars to gather towards the middle, and cooperating with the steel bar cutter 107 to achieve the cutting and transportation of steel bars one by one. The distance measuring sensor 108 is fixed to a suitable position on the outer shell of the driving mechanism by screws to accurately measure the length of the steel bars. The steel bar cutter 107 realizes the rotation cutting of the outer circle saw teeth through a central rotor, is designed with a crank structure, and its internal receiver cooperates with the distance measuring sensor 108 for real-time drive. It is installed at a suitable position on the outer shell and performs circular motion to cut steel.

[0041] 3. Select steel and make the storage tank a 303a and the storage tank b 303b by electric welding. Two vertical rods a 302a and b 302b are installed on the outside. A universal wheel set 309 is installed below the storage tanks. The classification moving rod 304 is fixed at the center between the storage tank a 303a and the storage tank b 303b by bolts. The two ends of the moving rod are perforated, and the hole centers are connected to the rotating shafts and fixed on the vertical rods. The rotation of the moving rod is realized through the drive of the transmission gear 306 and the servo motor 305. The semi-circular feeders a 301a and b 301b are collinear with the vertical rod 302a. Similarly, the rotation of the semi-circular robotic arm is realized by using the cooperation of the perforations, the rotating shafts, and the four-foot motor 307 to meet the functional requirements of storage and classification.
