Description

Technical Field

[0001] This utility model relates to the technical field of material sorting and counting equipment for production lines, and in particular to a control structure for a sorting counter. Background Technology

[0002] In manufacturing production lines for pipe fittings, small mechanical parts, and electronic components, only a single material feeding area is configured, and the width of the feeding area is fixed and narrow. It is impossible to adjust the feeding range according to the workpiece conveying volume. As a result, when the production line continuously conveys workpieces, all workpieces fall into the same feeding area, which easily stacks, squeezes, or even blocks the conveying channel below the feeding port. To address this accumulation problem, manual inspection and cleaning are required at regular intervals. To prevent the accumulation from worsening, the production line must be stopped during cleaning, which is time-consuming. In addition, frequent shutdowns not only disrupt the production rhythm and create production gaps in subsequent processes, but also accelerate the mechanical wear and tear of components such as the production line motor and conveyor belt, seriously affecting the continuous operation capability, production efficiency, and equipment lifespan of the production line. Utility Model Content

[0003] The purpose of this invention is to provide a control structure for a box-separating counter, which solves the problem in existing manufacturing production lines that only have a single material dropping area, the width of the material dropping area is fixed and narrow and cannot be adjusted according to the amount of workpieces being transported, which leads to the workpieces being concentrated in the same material dropping area and easily stacking below the material dropping port.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A control structure for a box-separating counter includes a fixed plate, a hydraulic cylinder fixedly mounted on the surface of the fixed plate, a movable rod disposed on the side of the fixed plate away from the hydraulic cylinder, a movable plate disposed on the surface of the movable rod, a connecting member disposed at the output end of the hydraulic cylinder, and a rotating member disposed on the surface of the movable rod. The movable rod is rotatably connected to the fixed plate through the rotating member. The hydraulic cylinder drives the connecting member to move on the fixed plate, thereby using the connecting member to drive the movable rod to reciprocate around the rotating member, thereby causing the movable plate to intermittently flip towards both sides.

[0006] Preferably, the rotating component includes a pin and a fixing component. The pin passes through the movable rod and the fixing plate. The surface of the pin is provided with an annular groove. The fixing component is fixed to the surface of the fixing plate by bolts and has an interference fit with the annular groove of the pin to restrict the pin, making it impossible for it to be easily pulled out of the fixing plate.

[0007] Preferably, the connector includes a mounting shaft and a connecting plate. The mounting shaft passes through the output end of the hydraulic cylinder and is fixed by bolts. The connecting plate is fixedly installed at the end after installation. The surface of the fixing plate has an elongated groove. The mounting shaft slides inside the elongated groove. The circumferential surface of the connecting plate has an annular groove. The surface of the movable rod has a movable groove. The connecting plate is embedded in the movable groove through the annular groove, so that when the connector reciprocates in the elongated groove, the connecting plate drives the movable rod to reciprocate around the rotating component.

[0008] Preferably, the end of the movable plate is provided with an ear plate, and the movable plate is fixed to the surface of the movable rod by the ear plate and bolts.

[0009] Preferably, the surface of the fixing plate is pre-drilled according to the equipment size, so as to facilitate fixing it to the conveying end of the equipment.

[0010] Preferably, a connecting plate is fixedly installed at the end of the fixed plate, and the hydraulic cylinder is horizontally fixed through the connecting plate.

[0011] This utility model has at least the following beneficial effects:

[0012] By using the intermittent flipping function of the movable plate, the original concentrated single material dropping area is transformed into a dual-area alternating material dropping mode, increasing the width of the material dropping area and realizing the dispersed collection of materials in the two material dropping areas. This completely avoids the problem of accumulation in a single area, eliminating the need for manual cleaning or machine shutdown, and ensuring the continuous operation of the production line 24 hours a day. It also reduces equipment wear and production interruptions caused by accumulation and improves production efficiency. Attached Figure Description

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Reference Figure 1-5 A control structure for a box-separating counter includes a fixed plate 1. A hydraulic cylinder 5 is fixedly mounted on the surface of the fixed plate 1. A movable rod 3 is provided on the side of the fixed plate 1 away from the hydraulic cylinder 5. A movable plate 2 is mounted on the surface of the movable rod 3. A connecting piece 6 is provided at the output end of the hydraulic cylinder 5. A rotating piece 4 is provided on the surface of the movable rod 3. The movable rod 3 is rotatably connected to the fixed plate 1 through the rotating piece 4. The hydraulic cylinder 5 drives the connecting piece 6 to move on the fixed plate 1, thereby using the connecting piece 6 to drive the movable rod 3 to reciprocate around the rotating piece 4, thereby causing the movable plate 2 to intermittently flip towards both sides.

[0023] The fixed plate 1 provides the installation support foundation for the entire structure, bearing the weight of components such as the hydraulic cylinder 5 and the movable rod 3; the hydraulic cylinder 5 is the power source, driving the connecting piece 6 to move through extension and retraction; the movable rod 3 is the transmission component, converting the linear motion of the connecting piece 6 into its own rotational motion, driving the movable plate 2 to move; the movable plate 2 directly contacts the material, guiding the material to the two side boxing stations by flipping; the connecting piece 6 transmits the power of the hydraulic cylinder, connecting the output end of the hydraulic cylinder to the movable rod 3; the rotating part 4 provides a rotation fulcrum for the movable rod 3, ensuring its stable reciprocating rotation.

[0024] Furthermore, the rotating component 4 includes a pin 41 and a fixing component 42. The pin 41 passes through the movable rod 3 and the fixing plate 1. The surface of the pin 41 is provided with an annular groove. The fixing component 42 is fixed to the surface of the fixing plate 1 by bolts and is interference-fitted with the annular groove of the pin 41 to restrict the pin 41, making it impossible for it to be easily pulled out of the fixing plate 1.

[0025] The pin 41 is the core rotating component. It provides the rotation axis for the movable rod 3 by passing through the movable rod 3 and the fixed plate 1, ensuring that the movable rod 3 rotates stably around it. The fixing part 42 restricts the axial movement of the pin 41 through the interference fit with the annular groove of the pin 41, preventing the pin 41 from coming out of the fixed plate 1 and the movable rod 3, while enhancing the overall connection stability of the rotating part 4. The annular groove provides a positioning reference for the fixing part 42, ensuring that the fixing part 42 can accurately limit the pin 41.

[0026] Furthermore, the connecting member 6 includes a mounting shaft 61 and a connecting plate 62. The mounting shaft 61 passes through the output end of the hydraulic cylinder 5 and is fixed by bolts. The connecting plate 62 is fixedly installed at the end after installation. The surface of the fixing plate 1 is provided with an elongated groove 11. The mounting shaft 61 slides inside the elongated groove 11. The circumferential surface of the connecting plate 62 is provided with an annular groove. The surface of the movable rod 3 is provided with a movable groove 31. The connecting plate 62 is embedded in the movable groove 31 through the annular groove, so that when the connecting member 6 moves back and forth in the elongated groove 11, the connecting plate 62 drives the movable rod 3 to swing back and forth around the rotating member 4.

[0027] Furthermore, the end of the movable plate 2 is provided with an ear plate 21, and the movable plate 2 is fixed to the surface of the movable rod 3 by the ear plate 21 and bolts.

[0028] Furthermore, the surface of the fixing plate 1 is pre-drilled according to the equipment size, so as to facilitate fixing it to the conveying end of the equipment.

[0029] Furthermore, a connecting plate is fixedly installed at the end of the fixing plate 1, and the hydraulic cylinder 5 is horizontally fixed through the connecting plate.

[0030] Furthermore, the rotating component 4 is located above the connecting component 6 so that the movable plate 2 is in a state where it faces downwards on both sides during rotation.

[0031] Furthermore, both the fixed plate 1 and the movable plate 2 are made of industrial-grade 316L stainless steel, and their outer surfaces are coated with a wear-resistant coating by plasma spraying. The wear-resistant coating is a tungsten carbide-based composite coating or a nano-ceramic coating.

[0032] Furthermore, the hydraulic cylinder 5 is externally connected to a hydraulic oil pump, which is a variable vane pump or a gear pump with a rated working pressure of 6-10 MPa. The hydraulic cylinder 5 and the hydraulic oil pump are connected via a high-pressure oil pipe and a sealing joint. The high-pressure oil pipe has a pressure resistance rating of not less than 16 MPa, and the sealing joint conforms to ISO 8434-1 standard. The hydraulic cylinder 5 establishes a signal connection with a counter through a controller, which is a PLC controller (such as a Siemens S7-1200). The counter is a photoelectric counter using through-beam photoelectric detection. The controller is electrically connected to the drive unit of the hydraulic oil pump, the solenoid directional valve of the hydraulic cylinder 5, and the counter. The counter is used to collect the quantity of material passing through and transmit the counting signal to the controller in real time. After receiving the counting signal, the controller generates corresponding control commands, adjusts the oil supply status of the hydraulic oil pump (including oil supply start and stop and oil supply flow) through the control commands, and controls the solenoid directional valve of the hydraulic cylinder 5 to perform directional operation, thereby realizing precise control of the extension and retraction of the hydraulic cylinder 5. At the same time, the flipping rhythm of the movable plate 2 is synchronously adjusted with the quantity of material collected by the counter.

[0033] In summary, the entire fixed plate 1 is installed at the end of the production line equipment by bolts and pre-drilled holes on the surface. After the equipment is started, the movable plate 2 maintains its initial orientation (such as the direction of the first side material box), and the material falls sequentially along the conveying channel; at the same time, the counting and detection module detects the number of falling materials in real time, and the counter accumulates once for each material that passes through.

[0034] Once the counter has accumulated and detected the required amount of material falling into the first side hopper, the counter immediately outputs a "reversal trigger signal" to the control unit of hydraulic cylinder 5, instructing the hydraulic valve to switch the oil circuit and start the hydraulic cylinder 5 to operate.

[0035] After receiving the trigger signal, the output end of the hydraulic cylinder 5 switches from the "initial retracted state" to the "extended state", driving the mounting shaft 61 fixed thereto to slide along the long groove 11 of the fixed plate 1 away from the connecting plate; at this time, the connecting plate 62 slides synchronously with the mounting shaft 61, and because the annular groove of the connecting plate 62 is embedded in the movable groove 31 of the movable rod 3, it provides power for the rotation of the movable rod 3.

[0036] When the connecting plate 62 slides, it applies a lateral thrust to the movable groove 31 of the movable rod 3 through the annular groove, forcing the movable rod 3 to rotate around the pin 41 toward the second side of the equipment conveying end; since the movable plate 2 is fixed to the movable rod 3, the movable plate 2 flips synchronously with the movable rod 3, and finally stabilizes toward the second side material box.

[0037] After the movable plate 2 faces the second side, the subsequently falling materials are guided to the material box on the second side, and the counting and detection module continues to accumulate the number of materials. When the number of materials is accumulated to 5 again, the counter outputs a "reverse trigger signal", which controls the output end of the hydraulic cylinder 5 to switch from "extended state" to "retracted state", driving the mounting shaft 61 to slide along the long groove 11 towards the connecting plate.

[0038] When the mounting shaft 61 retracts, the connecting plate 62 applies a reverse pulling force to the movable rod 3's movable groove 31 through the annular groove, forcing the movable rod 3 to rotate around the pin 41 to the first side, and the movable plate 2 simultaneously flips back to its initial orientation; thereafter, the above steps are repeated.

[0039] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
