Description

Technical Field

[0001] This application relates to the field of shot blasting machine control, and in particular to feeding control methods, devices and components for use with shot blasting machines. Background Technology

[0002] Currently, shot blasting machines generally use conveyor belts to add materials, such as workpieces to be shot blasted or shot balls to be added. This is usually done manually or with the assistance of a robotic arm, resulting in low automation, complex and discontinuous action cycles, and the need for process connection design.

[0003] When adding materials, there is a risk of residue buildup. Furthermore, traditional auxiliary equipment suffers from problems such as high noise levels and poor flexibility during operation.

[0004] Regarding the aforementioned technologies, the inventors believe that reducing the pace of movement, minimizing the need for auxiliary equipment, improving the continuity, integration, and coordination of movements, and reducing noise are urgent technical problems that need to be solved. Of course, in order to study this device, the inventors designed matching components to solve the technical problems of this invention, and innovated to solve the problems of this invention and / or the problems of this device in operation. Summary of the Invention

[0005] To address the aforementioned technical problems, this application provides a feeding control method, device, and components for use with a shot blasting machine, employing the following technical solution:

[0006] In order to achieve automated control and continuous operation and reduce the cycle time of actions, this invention provides a feeding control method for a shot blasting machine, the control method including the following steps;

[0007] In order to determine the position of the hopper and thus facilitate the execution of subsequent actions, S1, determine the work position of the hopper body. If the work position and state of the hopper body can be determined, proceed to step S2; otherwise, proceed to step S3. The hopper body includes an empty state and a loaded state. S2, based on the work position of the hopper body, continue to execute the subsequent operation steps.

[0008] To address unexpected situations at the detection location, step S3 involves manual intervention. The hopper body is moved to the designated station, and the station program is entered to confirm the location of the hopper body. Step S2 is then executed after confirmation.

[0009] As a further improvement to the above technical solution:

[0010] In order to determine the position, in step S1, the hopper body is determined to be at the corresponding work station position by the corresponding sensor and / or limit switch, and the hopper body is determined to be empty or loaded by the sensor at the corresponding work station.

[0011] As a judgment rule, when it is determined to be empty, the hopper body returns; when it is determined to be loaded, the hopper body moves forward.

[0012] To simplify control, this invention designs three workstations compared to existing technologies. In step S2, the workstation where the hopper body is located includes a discharge workstation, a transfer workstation, or a feeding workstation;

[0013] To achieve smooth operation and a compact cycle time, this invention sets standardized cycle times for each workstation. When the hopper is at the unloading station and is unloaded, it sequentially executes steps S21 (unloading), S22 (forward movement), S23 (tilting), S24 (tipping), S25 (reverse movement), and S26 (reset). When the hopper is at the transfer station and is loaded, it executes steps S23 (tilting), S24 (tipping), S25 (reverse movement), and S26 (reset). When unloaded, it executes steps S25 (reverse movement) and S26 (reset).

[0014] To implement the above method, a tilting feeding device for use with a shot blasting machine is provided. The tilting feeding device includes a frame assembly.

[0015] A set of rotating rollers for conveying hopper frame components is sequentially arranged on the frame assembly. The rotating rollers are sequentially equipped with a discharge station, a transfer station and a feeding station.

[0016] At the unloading station, there is a material dropping component, which is used to drop the pre-stored material into the hopper frame component;

[0017] At the transfer station, a flipping component is installed. The flipping component is used to receive the hopper frame assembly and separate the hopper frame assembly from the rotating roller group, so that the hopper frame assembly can move forward diagonally in a straight line and swing forward around the center to tilt; the hopper frame assembly can move forward diagonally in a straight line and swing forward around the center in combination or one by one.

[0018] At the feeding station, there is a corresponding feed inlet for the shot blasting machine, which is used to receive the material poured out by the hopper frame assembly.

[0019] As an extension, a shot blasting machine includes a tilting feeder for use with the shot blasting machine and the shot blasting machine itself. During operation, the inlet of the shot blasting machine is opened, and the material is poured in.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] This invention enables automatic quantitative feeding, automatic transportation, and automatic tilting of materials. The actions are seamless and can be achieved through limit switches, or sensors can be used. This eliminates the need for a robotic arm, reduces interruptions during cycle transitions, and makes material output more convenient during tilting.

[0022] Specific advantages include material feeding via a hopper frame assembly, support via a frame assembly, information collection via a data acquisition module, assisted hopper tilting output via a tilting assembly, material falling at the unloading station, changes in hopper working status at the transfer station, material output at the feeding station, better material output via a tilting hopper nozzle, improved material output via a slope, protection pads at the hopper nozzle to prevent damage to the hopper body during contact and collision, preferred side guide blocks for guiding support, material storage within the hopper cavity, hopper output via a rotating roller assembly, and roller process gaps to accommodate the lower crossbeam of the frame, thus preventing obstruction during separation. The tilting hinge provides support, the swing guide slide is optional, and the tilting guide slider is not essential. The tilting frame encompasses the hopper and tilts it, the drive unit provides actuation, the front opening of the frame allows for material output, the frame's contoured baffle provides support, the frame's side guide rails, the lower arched bridge legs, and the lower arch of the frame achieve better fit clearance, facilitating hopper handover and preventing jamming. The tilting shaft provides support, the limit switch determines the position, the connecting hinge plate, and the cleaning component clears accumulated material. The storage section, with its swinging component, achieves automatic feeding; when the material reaches the set weight, it automatically resets, operating smoothly without jamming.

[0034] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0035] like Figure 1 As shown in this embodiment, the feeding control method for a shot blasting machine includes the following steps: First, a startup is initiated. During the first operation, the program is initialized. Alternatively, the program from the previous shutdown can be continued, stored and retrieved via hard disk. The name of this invention is used to distinguish it from other inventions, indicating that they aim to achieve a common technical effect, such as cleaning a buffer pad; the buffer pad is mentioned as part of the cleaning effect.

[0036] S1, determine the position of the hopper body 8. If the position and state of the hopper body 8 can be determined, proceed to step S2; otherwise, proceed to step S3. The hopper body 8 includes an empty state and a loaded state. This invention determines the action rhythm and the next action to be performed by judging the load and position of the hopper.

[0037] S2, based on the station where the hopper body 8 is located, continues to execute subsequent operation steps; thereby greatly improving work efficiency and reducing the intervention of the robotic arm.

[0038] S3, manual intervention: The hopper body 8 is sent to the designated station, and the station program is entered to confirm the station where the hopper body 8 is located. After confirmation, step S2 is executed. For undetected hopper bodies, the operator, depending on the situation, sends them to the corresponding station or the sensed location, retrieves the program for that location from the program, and executes it.

[0039] like Figure 2 As a refinement of each execution step, in step S1, the position of the hopper body 8 at the corresponding work station is determined by the corresponding sensor and / or limit switch, and the hopper body 8 is determined to be in an empty or loaded state by the sensor at the corresponding work station; the sensor includes a gravity sensor, a camera or other similar components.

[0040] As a judgment rule, when it is determined to be empty, the hopper body 8 returns; when it is determined to be loaded, the hopper body 8 moves forward. A weight threshold can be set to accommodate the weight difference between different hopper bodies.

[0041] In step S2, the workstations where the hopper body 8 is located include the unloading workstation 5, the transfer workstation 6, or the feeding workstation 7; the present invention achieves a compact rhythm and smooth operation by cleverly designing these three workstations.

[0042] For example, when the hopper body 8 is at the unloading station 5 and is in an unloaded state, the hopper body 8 sequentially executes steps S21, unloading step; S22, forward step; S23, flipping step; S24, tilting step; S25, backward step; S26, resetting step.

[0043] For example, when the hopper body 8 is at the transfer station 6, if it is in a loaded state, the following steps are executed: S23, flipping step; S24, tilting step; S25, reversing step; S26, resetting step; if it is in an unloaded state, the following steps are executed: S25, reversing step; S26, resetting step.

[0044] For example, when the hopper body 8 is at the feeding station 7, if it is in a loaded state, the following steps are executed: S23, flipping step; S24, tilting step; S25, reversing step; S26, resetting step; if it is in an unloaded state, the following steps are executed: S25, reversing step; S26, resetting step.

[0045] Combination Figures 4-10As a specific action description, in S21, during the unloading step, firstly, the unloaded hopper body 8 swings and tilts backward and downward at the swing conveyor roller section 44 of the unloading station 5; then, the material falls from the storage section 40 into the front half 49, causing the center of gravity of the hopper body 8 to shift forward, thereby causing the swing conveyor roller section 44 to become horizontal or forward tilted, preferably slightly tilted upward, so as to make it easier for the hopper carrying the material to move forward and reduce the power during startup. Of course, the horizontal state is also within the protection range.

[0046] In S22, during the forward movement, the fully loaded hopper body 8 moves up to the transfer station 6 via the rotating roller group 13, where it waits to be turned over.

[0047] In S23, during the flipping step, firstly, the limit switch 28 drives the flipping frame 18 to flip, so that the flipping guide slider 17 slides on the swing guide slide 16. Under the action of its own weight, the fully loaded hopper body 8 slides along the frame side guide rail 23 to the feeding station.

[0048] As a preferred travel trajectory, in step S24, the tilting nozzle 9 of the hopper first protrudes from the front opening of the tilting frame 18 at the feeding station 7 to tilt the material; then, the trajectory of the tilting frame 18 includes at least a straight upward oblique trajectory and a swing trajectory around a fixed center, which are either combined or performed one at a time; thus, the material is smoothly removed. The motion trajectory used in this invention has an upward separation force F in the initial stage. 上 Greater than the horizontal forward component F 前 This allows the hopper to better separate upwards from the rotating rollers, while simultaneously stabilizing the forward speed and preventing jamming or collisions, ensuring good continuity. In the later stages, the acceleration generated by the driving force of the drive unit 20 on the material continuously increases, while its front opening swings forward and downward. As a result, the material swings forward in a parabolic motion under the action of inertial force, while the hopper body makes a downward circular motion, thus achieving separation. Its operation is smooth and has low resistance.

[0049] As a subsequent return stroke, it is also within the protection range. In S25, during the retraction step, firstly, the hopper body 8 becomes horizontal; then, the hopper body 8 retracts to the unloading station.

[0050] In step S26, during the reset step, the hopper body 8, due to its center of gravity being in the rear half, swings and tilts backward and downward on the swing conveyor roller section 44, waiting for material to be discharged.

[0051] To achieve the above control method, such as Figure 3 The present invention is equipped with a control system; the control system includes the following components: a data acquisition module 3, which is set at each workstation and is used to acquire the position information and / or load information of the hopper body 8;

[0052] The main controller retrieves preset instructions based on the information collected by the acquisition module 3;

[0053] The execution module receives control commands from the main controller and controls the corresponding modules to execute the corresponding steps.

[0054] The backup controller sends heartbeat commands to the main controller at regular intervals and frequencies. After receiving the heartbeat command, the main controller sends feedback information to the backup controller at regular intervals and frequencies. If the backup controller does not receive feedback information within the set time and time interval, it determines that the main controller has failed and alarms through the alarm module. The main controller is downgraded to a backup controller, and the backup controller is upgraded to a new main controller.

[0055] The detection module is used to detect whether the hopper body 8 and / or the corresponding module are in place. If they are not in place, an alarm will be triggered by the alarm module.

[0056] Acquisition module 3 includes a gravity sensor;

[0057] The data acquisition module 3 includes a position sensor or a limit switch.

[0058] The control system of this invention also includes a power supply circuit, a voltage regulator circuit, a clock module, an emergency stop module, etc.

[0059] like Figures 4-10 The tilting feeding device used in this embodiment for the shot blasting machine performs the above method; the tilting feeding device includes a frame assembly 2, which is a general term and can be a separate or integral part, in short, a fixed support component;

[0060] A rotating roller group 13 for conveying the hopper frame assembly 1 is sequentially arranged on the frame assembly 2. As an extension, the conveying mechanism may also include a part of the conveyor belt, chain or push rod, etc. The rotating roller group 13 is sequentially provided with a feeding station 5, a transfer station 6 and a feeding station 7.

[0061] At the unloading station 5, a material dropping component is provided. As an extension, it can be a mechanical gripper, a funnel, or other conventional dropping mechanism. The material dropping component is used to drop the pre-stored material into the hopper frame component 1. The material can be shot blasting balls or corundum, etc. As an extension, it also includes impact-resistant shot blasting materials, such as casting handle blanks, impact-resistant workpieces that are not easily deformed.

[0062] As a device for realizing the motion trajectory, a flipping component 4 is provided at the transfer station 6. The flipping component 4 is used to receive the hopper frame assembly 1 and separate the hopper frame assembly 1 from the rotating roller group 13, so that the hopper frame assembly 1 moves forward diagonally in a straight line and moves forward and tilts around the center. The hopper frame assembly 1 moves forward diagonally in a straight line and moves forward and tilts around the center in a combination or one by one. It is preferably driven by a push rod, but other drive structures are not excluded.

[0063] At feeding station 7, there is a corresponding feed inlet for the shot blasting machine. The feed inlet of the shot blasting machine is used to receive the material poured out by the hopper frame assembly 1, thereby realizing the entry of the material.

[0064] Several acquisition modules 3 are distributed on the rack assembly 2; this is a general term, and the required sensors or switches can be selected according to the required functions.

[0065] The hopper frame assembly 1 includes a hopper body 8, the shape of which is not limited to the attached drawings. The front end of the hopper body 8 has a hopper tilting spout 9, and a hopper spout guard 10 is located below the lower lip of the hopper tilting spout 9 to prevent collisions during tilting. Hopper side guide blocks 11 are provided on both sides of the hopper body 8 to facilitate forward movement. The hopper body 8 has a hopper cavity 12 with at least an upper opening, thus enabling material feeding and discharging.

[0066] As an example, the rotating roller group 13 includes a plurality of rotating rollers that roll and rotate; there is a roller process gap 14 between adjacent rotating rollers; thereby realizing the load transmission.

[0067] To facilitate flipping and achieve the aforementioned parabolic trajectory, the flipping assembly 4 includes a flipping hinge seat 15; a swing guide slide 16 rotates on the flipping hinge seat 15, and a flipping guide slider 17 slides linearly on the swing guide slide 16; a circle is drawn with the center of the flipping hinge seat 15 as the center, and the point of intersection of this circle and the travel trajectory of the flipping guide slider 17 is the radius R, and this circle is tangent to the travel trajectory of the flipping guide slider 17; a flipping frame 18 is provided on the flipping guide slider 17;

[0068] An internal channel 19 is provided inside the tilting frame 18, and a front opening 21 is provided at the front end of the tilting frame 18. A front bottom plate is inclinedly provided at the lower part of the front opening 21. A frame-shaped baffle 22 is provided on the tilting frame 18 to prevent the hopper body 8 located in the internal channel 19 from tilting and separating from the frame-shaped baffle 22. At the same time, the material is allowed to be poured out from the front opening 21.

[0069] The two inner walls of the flipping frame 18 are provided with frame side guide rails 23, which are used to match the hopper side guide blocks 11; thus, the hopper can enter smoothly, but this is not necessary.

[0070] A tilting shaft 27 is coaxially arranged on both outer sides of the tilting frame 18. A drive unit 20 is arranged between the tilting shaft 27 and the frame assembly 2. The drive unit 20 drives the tilting frame 18 to move. Its drive is not limited to push rods, but can be hydraulic cylinders, etc.

[0071] A lower arch bridge support leg 24 is provided at the bottom of the flipping frame 18, and a lower arch portion 25 is provided between the lower arch bridge support legs 24; a lower crossbeam 26 is connected between the two lower arch portions 25; when the lower arch portion 25 rides on the corresponding rotating roller, the lower crossbeam 26 is located in the roller process gap 14, and the upper surface of the lower crossbeam 26 is lower than the upper surface of the rotating roller; this is another small innovation of the present invention. Among them, limit switches 28 are provided at least at the unloading station 5, the transfer station 6, and the feeding station 7.

[0072] For the hopper body 8, a cleaning component is provided in the hopper cavity 12; this allows for better output of materials from the hopper. This innovation is currently still in the experimental stage and is an optional feature. The concept is to use two ropes: first, the front rope is pulled taut and the back rope is loosened to open the cleaning plate and clean the materials. Then, the back rope is pulled and the front rope is loosened to reset the cleaning plate, thus achieving more thorough dumping of materials without taking up space.

[0073] The cleaning assembly includes a connecting hinge plate 29 hinged at the upper end to the rear side wall of the hopper body 8, a cleaning hinge plate 30 hinged at the lower part of the connecting hinge plate 29, and a cleaning buffer pad 31 for contacting the inner wall of the hopper body 8 at the front end of the cleaning hinge plate 30, thereby playing a buffering role.

[0074] A rear pulling process hole 32 is provided on the rear side wall of the hopper body 8, and a front pulling process hole 34 is provided on the hopper tilting nozzle 9. Hinge plate connecting seats 33 are provided on both sides of the cleaning hinge plate 30.

[0075] A rear winch assembly 39 is provided at the rear end of the rack assembly 2;

[0076] A front guide roller 36 is provided at the front end of the frame assembly 2, located in front of the tilting assembly 4, and a front hoisting assembly 37 is provided below the front guide roller 36;

[0077] A front pull rope 35, which passes through the front guide roller 36, the flip frame 18, and the front pull process hole 34, is connected between the front hoist assembly 37 and the corresponding hinge plate connecting seat 33.

[0078] A rear pull rope 38 passing through the rear pull process hole 32 is connected between the rear winch assembly 39 and the corresponding hinge plate connecting seat 33.

[0079] As an improvement to the unloading point, the unloading assembly includes a storage section 40 located above the unloading station 5; a half-shaft rotating part 41 is provided at the lower outlet of the storage section 40 for opening or closing the lower outlet to discharge material downwards.

[0080] A swing conveyor roller section 44 is provided below the unloading station 5 to connect to the corresponding rotating roller.

[0081] At both ends of the middle part of the swing conveyor roller section 44, there are corresponding swing shaft heads 42, and swing support seats 43 are provided on the swing shaft heads 42. The swing shaft heads 42 are swinging on the swing support seats 43.

[0082] An arc-shaped swing guide slide 45 is provided on the swing support 43, with the swing guide slide 45 centered on the swing shaft head 42;

[0083] A swing guide column 46 located in the swing guide slide 45 is provided at the rear end of the swing conveyor roller section 44.

[0084] A spring buffer plate 47 is provided on the frame of the swing conveyor roller section 44 to support the downward swinging hopper body 8.

[0085] A limiting part 48 is provided on the frame assembly 2 to limit the swing angle of the swing conveyor roller part 44;

[0086] The hopper body 8 has a hopper cavity 12 with a front half 49 and a rear half 50.

[0087] When the hopper body 8 is unloaded, the swing conveyor roller 44 swings backward and tilts downward; the material falls from the storage section 40 into the front half 49, causing the center of gravity of the hopper body 8 to shift forward to the front half 49, thereby causing the swing conveyor roller 44 to become horizontal or tilted forward.

[0088] When unloaded, the center of gravity of the hopper body 8 is in the rear half 50, and when fully loaded, the center of gravity of the hopper body 8 is in the front half 49.

[0089] This innovation cleverly employs a seesaw structure to achieve dispersed and quantitative collection of materials, and automatically fills the container by changing the center of gravity.

[0090] As an extended protection, the shot blasting equipment in this embodiment includes a tilting feeder for use with the shot blasting machine and the shot blasting machine.

[0091] The preferred principle of a feeding control method for a shot blasting machine is as follows: When the user uses it,

[0092] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
