Description

Technical Field

[0001] This utility model belongs to the field of steel drum manufacturing technology, and specifically relates to an automatic waste collection device. Background Technology

[0002] In the steel drum manufacturing industry, steel strip, as the core raw material, needs to be formed through multiple stamping and cutting processes. Among them, the cutting of the circular drum bottom is a key step - after the steel strip is cut into a circular drum bottom along a preset trajectory by laser or punching, the remaining edge part of the steel strip (i.e., waste material) will be left below the cutting station in the form of continuous strips or scattered fragments.

[0003] Traditional steel drum scrap collection relies heavily on manual labor: workers use simple pliers or suction cups to repeatedly pick up scrap along the cutting line and put it into a turnover box. The drawbacks are that the steel strips are cut quickly, making manual collection not only labor-intensive and inefficient, but also posing safety hazards such as cuts from cutting debris and collisions with moving equipment. Utility Model Content

[0004] The purpose of this invention is to provide an automatic waste collection device that, through precise position detection and reliable execution control, adapts to the waste handling needs of high-speed production lines, thereby improving production continuity and intelligence.

[0005] The purpose of this utility model is achieved as follows: An automatic waste collection device includes a frame, on which a material placement platform is provided. Waste is placed on the material placement platform. A suction and discharge device and a displacement device are provided above the waste. The suction and discharge device can reciprocate linearly along the length of the frame through the displacement device to switch back and forth between the suction station and the discharge station. The suction and discharge device includes a horizontally arranged transfer frame. Several electromagnets are provided on the lower side of the transfer frame corresponding to the waste. The upper side is fixedly connected to the output end of the displacement device through a mounting base. A proximity switch one and a proximity switch two are respectively provided on the frame corresponding to the suction station and the discharge station. A sensing block is provided on the front side of the transfer frame. The electromagnets, proximity switch one, and proximity switch two are all electrically connected to a controller. When the controller receives an electrical signal from proximity switch one, it controls several electromagnets to be energized simultaneously. When it receives an electrical signal from proximity switch two, it controls several electromagnets to be de-energized simultaneously.

[0006] In use, the displacement device first drives the transfer frame to move along the length of the frame from the initial position to the suction station. When the induction block on the front side of the transfer frame triggers the proximity switch one corresponding to the suction station on the frame, the controller receives the signal and immediately controls several electromagnets on the lower side of the transfer frame to be energized simultaneously. The electromagnets generate magnetic force to attract the metal waste that is dispersed or continuously distributed on the placement platform. Then, the displacement device continues to drive the transfer frame with the attracted waste to move to the discharge station. When the induction block triggers the proximity switch two corresponding to the discharge station, the controller receives the signal again and controls all electromagnets to be de-energized simultaneously. After losing the attraction force, the waste falls into the collection container of the discharge station. After completing a single adsorption-release cycle, the transfer frame returns to the initial position under the drive of the displacement device, waiting for the next trigger signal of proximity switch one. This process is repeated to achieve continuous, precise and automated collection of waste.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: The device drives the transfer frame to reciprocate through the displacement device, and combined with the logic control of the proximity switch and the controller, it automatically completes the "material suction-displacement-discharge" process without manual handling or intervention, significantly reducing labor intensity and adapting to the needs of continuous and high-speed production; The displacement device drives the transfer frame to reciprocate in a straight line along the length of the frame. With the horizontal design of the transfer frame, the straightness of the electromagnet's movement trajectory can be guaranteed, avoiding adsorption failure caused by shaking and improving the stability of system operation; After the electromagnet is de-energized, the waste material falls vertically into the collection container at the discharge station. The landing point is consistent and evenly distributed, forming a neatly stacked waste pile, which has high operating efficiency and facilitates subsequent packaging work.

[0008] As a further improvement of this utility model, the displacement device includes a servo motor mounted on the machine body. The output shaft of the servo motor is coaxially provided with a drive wheel. The drive wheel is connected to the driven wheel via a synchronous belt. The beginning and end of the synchronous belt are fixed on the mounting base. Both the drive wheel and the driven wheel are mounted on the machine body via bearing seats.

[0009] As a further improvement of this utility model, a tray is provided below the feeding station, and the tray is used to receive waste materials.

[0010] As a further improvement of this utility model, the waste material has a parallelogram structure, including a hollow part composed of several circles of equal size and a solid frame surrounding the hollow part, with several electromagnets arranged corresponding to the solid frame.

[0011] As a further improvement of this utility model, several of the circular shapes are distributed at equal intervals along the length of the waste material.

[0012] As a further improvement of this utility model, the transplanting frame includes horizontally arranged horizontal tubes 1, 2, 3, 4, and 5, and longitudinally arranged vertical tubes 1, 2, 3, and 4; the left end of horizontal tube 1 is welded to the upper end of vertical tube 1, and the right end is welded to the upper end of vertical tube 3; the left end of horizontal tube 2 is welded to vertical tube 1, and the right end is welded to the upper end of vertical tube 4; the left end of horizontal tube 3 is welded to the midpoint of vertical tube 1, and the right end is welded to the midpoint of vertical tube 4; a large electromagnet is installed at the center of horizontal tube 4, and its left end is welded to vertical tube 1.

[0013] As a further improvement of this utility model, the transplanting frame is constructed by welding several 30mm*40mm square tubes to form a frame structure of 1180mm*1270mm.

[0014] As a further improvement of this utility model, the machine body is provided with two guide rails along its own length direction, and the guide rails are slidably connected to the transplanter frame through a number of sliders.

[0023] like Figure 1-6 As shown, an automatic waste collection device includes a frame 1, a material placement platform 2 on the frame 1, waste 3 placed on the material placement platform 2, and a suction / discharge device and a displacement device above the waste 3. The suction / discharge device can reciprocate linearly along the length of the frame 1 via the displacement device to switch back and forth between the suction station and the discharge station. The suction / discharge device includes a horizontally arranged transfer frame 4, with several electromagnets on the lower side of the transfer frame 4 corresponding to the waste 3, and the upper side is fixedly connected to the output end of the displacement device via a mounting base 5. A proximity switch 6 and a proximity switch 7 are respectively arranged on the frame 1 corresponding to the suction station and the discharge station. A sensing block 8 is arranged on the front side of the transfer frame 4. The electromagnets, proximity switch 6, and proximity switch 7 are all electrically connected to a controller. When the controller receives an electrical signal from proximity switch 6, it controls several electromagnets to be energized simultaneously. When it receives an electrical signal from proximity switch 7, it controls several electromagnets to be de-energized simultaneously. A tray 9 is arranged below the discharge station to receive the waste 3.

[0024] In this embodiment, the waste material 3 is cut into a parallelogram structure by a slant shearing machine. Specifically, it includes a hollow part 301 composed of six circles of equal size that are staggered at equal intervals along the length of the waste material 3, and a solid frame 302 disposed around the hollow part 301. The electromagnet is disposed corresponding to the solid frame 302.

[0025] The transplanting frame 4 is constructed from square tubes with a cross-section of 30mm*40mm, forming a frame structure of 1180mm*1270mm. Specifically, the transplanting frame 4 includes horizontally arranged horizontal tubes 401, 402, 403, 404, and 405, and longitudinally arranged vertical tubes 406, 407, 408, and 409. The left end of horizontal tube 401 is welded to the upper end of vertical tube 406, and the right end is welded to the upper end of vertical tube 408. The left end of horizontal tube 402 is welded to vertical tube 406, and the right end is welded to the upper end of vertical tube 409. The left end of horizontal tube 403 is welded to the midpoint of vertical tube 406, and the right end is welded to the midpoint of vertical tube 409. The center of horizontal tube 404 is... A large electromagnet 17 is installed, with its left end welded to the first longitudinal tube 406 and its right end welded to the lower end of the fourth longitudinal tube 409; the left end of the fifth horizontal tube 405 is welded to the lower end of the first longitudinal tube 406 and its right end is welded to the lower end of the fourth longitudinal tube 409; the upper ends of the second and third longitudinal tubes 407 and 408 are both welded to the second horizontal bar, and a large electromagnet 17 is installed at the connection point; the lower ends of both are welded to the fourth horizontal bar; between the second and third longitudinal tubes 407 and 408, there are symmetrically distributed horizontal tubes 410 and 411, with the third horizontal tube 403 as the center; small electromagnets 18 are installed at both ends of the sixth horizontal tube 410 and at the center of the seventh horizontal tube 411; the mounting base 5 is installed at the connection point between the third horizontal tube 403 and the first longitudinal tube 406.

[0026] The displacement device includes a servo motor 10 mounted on the machine body. The output shaft of the servo motor 10 is coaxially mounted with a drive wheel 11 via a coupling. The drive wheel 11 is connected to the driven wheel 13 via a synchronous belt 12. The beginning and end of the synchronous belt 12 are fixed to the mounting base 5 with screws. Both the drive wheel 11 and the driven wheel 13 are mounted on the machine body via bearing seats 14.

[0027] The electrical control system of the automatic waste collection device 3 is integrated into a small electrical cabinet. Through modular design, it achieves precise coordination of transplanting, adsorption, and logic control. Among them, the SV630P servo driver serves as the core of power control, responsible for driving the servo motor 10, which in turn drives the transplanting frame 4 to reciprocate along the guide rail 15, realizing precise switching between the suction and release stations. The NDR-240-24 small power module converts the external 240V input voltage into 24V DC power, providing stable power to the EDC-24T electromagnetic controller. The latter controls the on / off state of several electromagnets under the transplanting frame 4 to realize the adsorption and release of waste 3. The FX3G-24M PLC serves as the overall computing center, receiving the station signals from proximity switches one / two and the equipment status feedback, ensuring the automation and stability of waste 3 collection.

[0028] The machine body is made of square tubes with dimensions of "100mm*100mm*5mm" welded into a floor-shaped frame structure with dimensions of "1270mm*1180mm*3000mm". Two guide rails 15 are set along the length of the machine body. The two guide rails 15 are slidably connected to horizontal tube 1 401 and horizontal tube 5 405 respectively through several sliders 16. The double guide rails 15 constrain the degree of freedom of the transplanter 4 in the lateral direction, avoiding lateral deviation or shaking of the single guide rail 15 due to manufacturing errors, uneven force or external disturbances (such as the impact force when the waste material 3 is absorbed).

[0029] The working principle of this utility model is as follows: In the initial state, the transplanting frame 4 is located above the material placement platform 2, and the electromagnets on its lower side are de-energized. During operation, the FX3G-24M PLC, acting as the central controller, issues a start command. The SV630P servo driver drives the servo motor 10 to rotate, which in turn drives the mounting base 5 to move linearly along the double guide rails 15 of the machine body via the drive wheel 11 and the synchronous belt 12, thereby driving the transplanting frame 4 to move from the initial position to the suction station. When the induction block 8 on the front side of the transplanting frame 4 triggers the proximity switch 6 on the frame 1 corresponding to the suction station, the PLC receives the signal and controls the EDC-24T electromagnetic controller in conjunction, causing all the electromagnets on the lower side of the transplanting frame 4 to be energized simultaneously, generating magnetic force to attract the regularly arranged metal waste 3 on the material placement platform 2 (the electromagnets precisely correspond to the area of ​​the solid frame 302 for attraction, avoiding the dispersion of the attraction force caused by the hollow part 301). After adsorption is complete, the servo motor 10 continues to drive the transfer rack 4, which is loaded with waste material 3, to move towards the discharge station. When the sensing block 8 triggers the proximity switch 7 of the corresponding discharge station, the PLC receives the signal again and controls the electromagnetic controller to simultaneously cut off the power supply to all electromagnets. After losing its adsorption force, the waste material 3 falls vertically into the tray 9 below the discharge station, completing a single transfer of waste material 3. Subsequently, the servo motor 10 drives the transfer rack 4 in the reverse direction to return to the initial position along the guide rail 15, waiting for the trigger signal of the next proximity switch 6. This cycle repeats continuously, realizing the continuous automated collection of waste material 3 from suction, displacement to discharge. The entire process is precisely coordinated by the electronic control system for displacement and adsorption actions, ensuring collection efficiency and reliability.

[0030] The advantages of this utility model are as follows: the multi-electromagnet layout of the transplanting rack 4 (with 18 large and small electromagnets arranged in separate areas) and the uniform displacement control of the servo motor 10 ensure that the waste material 3 falls vertically onto the tray 9 when released, and the stacking shape is neat (such as the solid frame 302 aligned), avoiding the problem of scattering during manual collection; the neatly stacked waste material 3 has small gaps and a compact volume, which not only reduces the storage space occupied, but also facilitates forklift transfer to the reprocessing process, improving the efficiency of the entire chain from collection to post-processing; the device has a simple structure, low investment cost, and convenient maintenance and repair.

[0031] This utility model is not limited to the above embodiments. Based on the technical solutions disclosed in this utility model, those skilled in the art can make some substitutions and modifications to some of the technical features without creative labor, and these substitutions and modifications are all within the protection scope of this utility model.
