Description

Technical Field

[0001] The present invention relates to the technical field of workpiece counting and detection, in particular to a counting device and a counting method thereof applied to electrical automation. Background Art

[0002] An annular, sheet-shaped workpiece conveying and counting device based on electrical automation is used to achieve continuous, automatic conveying and precise counting of workpieces, thereby improving production efficiency, ensuring product quality, reducing human error, and enabling intelligent management of the production process. The device consists of a conveyor track or belt, sensors, a control unit, and a display or storage device. The annular track design facilitates continuous, cyclical conveying of workpieces. Sensors (such as photoelectric or proximity sensors) detect the arrival and departure of workpieces. The control unit (typically a PLC or industrial computer) receives signals, automatically updates the count, and controls related mechanical operations. The overall process: When a workpiece passes the sensor, a signal is transmitted to the control system, which automatically increments the count, ensuring that each workpiece is accurately counted and avoiding errors caused by manual counting. The system can also be equipped with an adjustment device to adapt to workpieces of different sizes, a fault detection system to ensure the stable operation of the equipment, and an emergency stop button to deal with emergencies. However, during the use of the current counting device, the annular sheet workpiece is basically in a lying state, and its shape is similar to a flat ring or disk. Due to its structural characteristics, the surface area of ​​the workpiece is large and the thickness is relatively thin. When the annular sheet workpieces are densely arranged in a lying posture, the edge spacing of adjacent workpieces is extremely small or even partially overlapped, resulting in the sensor detection area being covered by multiple workpieces at the same time. The light beam of the photoelectric sensor or the electromagnetic field of the proximity sensor may penetrate the gap between the workpieces or be reflected by the adjacent workpieces, forming a "continuous signal coverage area". The device cannot effectively distinguish the passing event of a single workpiece. For example, when the workpiece spacing is less than the minimum recognizable interval of the sensor, the edges of adjacent workpieces will enter the same detection area, causing the device to identify two passes as a single trigger, resulting in missed detection and false detection. Summary of the Invention

[0003] The purpose of the present invention is to provide a counting device and a counting method thereof for electrical automation, wherein a reduction motor and a front belt conveyor send annular sheet workpieces into a storage area formed by an annular enclosure and a carrying plate, and a worm gear rotating table receives the rotational power from the front belt conveyor through a gear-type belt composite transmission structure, so that the turntable transfers the annular sheet workpieces to the discharge part of the carrying plate through the through hole, and the annular sheet workpieces fall through the discharge part and pass through the frame-type counting sensor. The counted annular sheet workpieces continue to be sent out by the rear belt conveyor to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned object, the present invention provides the following technical solution: a counting device applied to electrical automation, comprising:

[0005] The top of the worm gear rotating platform is installed on the outer wall of the horizontal I-beam frame above the rear belt conveyor, and a turntable is installed on the top of the output shaft of the worm gear rotating platform, and an annular surrounding is fixed on the outer wall of the horizontal I-beam frame above the turntable. A carrying plate is fixed on the top of the worm gear rotating platform below the turntable, and a discharging portion is provided at an edge position of one side of the bottom end of the carrying plate, and a frame-type counting sensor is installed on the bottom end of the carrying plate below the discharging portion. A plurality of through holes in an annular array with equal spacing are opened in the interior of the turntable, and a height-adjustable material resistance component is installed on the outer wall of the annular surrounding.

[0006] A gear-type belt composite transmission structure is arranged on the other side of the horizontal I-frame surface, and is used to transmit the rotational power of the front belt conveyor to the worm gear rotating table and the rear belt conveyor. A control panel electrically connected to the reduction motor and the input end of the height-adjustable material resistance component is installed on one side of the horizontal I-frame surface, and the output end of the frame-type counting sensor is electrically connected to the input end of the control panel.

[0007] Preferably, the front belt conveyor includes a main shaft, a secondary shaft and pulleys rotatably installed on both sides of the top of the horizontal I-frame, fixed at one end of the surface of the main shaft and the secondary shaft, a conveyor belt is set between the two pulleys, and the output shaft of the reduction motor is fixedly connected to one end of the main shaft.

[0008] Preferably, the top ends of the horizontal I-shaped frames on both sides of the conveyor belt are bolted with guide bars, a gap is provided between the two guide bars, and the lower surface of the guide bar contacts the upper surface of the conveyor belt.

[0009] Preferably, a bending portion is provided at one end of the material guide strip close to the annular portion.

[0010] Preferably, the height-adjustable material blocking assembly includes a circular frame fixed on the front and rear outer walls of the annular enclosure, a top plate fixed between the two circular frames, and a screw electric lifting module installed inside one of the circular frames. The movable end of the screw electric lifting module is equipped with two symmetrical material blocking arms, which are located below the bending portion of the material guide strip.

[0011] Preferably, the front and rear outer walls surrounded by the ring are both provided with rectangular recessed portions for the blocking arm to slide in the Z-axis.

[0012] Preferably, the worm gear rotating table includes a casing fixed on the outer wall of one side of the horizontal I-frame, a vertical shaft rotatably installed at the center position inside the casing, and a worm shaft rotatably installed on one side of the casing. One end of the surface of the vertical shaft is fixed with a worm gear disk that meshes with the worm shaft. The top end of the vertical shaft passes through the outside of the casing and is fixedly connected to the center position of the bottom end of the turntable. The supporting plate is fixed to the top of the casing. One end of the worm shaft passes through the outside of the casing and is powered by the front belt conveyor and the rear belt conveyor through a gear-type belt composite transmission structure.

[0013] Preferably, the gear-type belt composite transmission structure includes a first gear shaft, a second gear shaft, and a third gear fixed to one end of the worm shaft, which are rotatably installed on one side of the horizontal I-frame surface. The first gear shaft, the second gear shaft, and the third gear are meshed in sequence, and one end of the secondary shaft is installed with a front belt transmission structure for driving the first gear shaft to rotate.

[0014] Preferably, a rear belt transmission structure for power transmission is installed between one end of the worm shaft and the rear belt conveyor.

[0015] The present invention also provides a counting method applied to electrical automation, such as the counting device applied to electrical automation described above, comprising the following steps:

[0016] S101: Start the device through the control panel to conduct a no-load test run to observe whether the turntable rotates smoothly and whether the alignment period of the discharge portion and the through hole is consistent. At the same time, start the height-adjustable material blocking assembly through the control panel to make the movable end of the height-adjustable material blocking assembly contact the upper surface of the turntable;

[0017] S102: The staff sets the speed of the reduction motor on the control panel according to the workpiece specifications. The speed of the turntable must match the feeding rate of the front belt conveyor to ensure that the workpiece accumulation in the storage area formed by the circular enclosure and the carrier plate is appropriate. The circular sheet workpieces are placed in batches at the starting end of the front belt conveyor, and the reduction motor is started at low speed. The workpieces are smoothly fed into the storage area formed by the circular enclosure and the carrier plate via the front belt conveyor;

[0018] S103: The front belt conveyor transmits the rotational power to the worm gear rotary table and the rear belt conveyor through the gear-belt composite transmission structure. The worm gear rotary table then drives the turntable to rotate. A single workpiece falls into the through hole and is transferred with the turntable to the discharge portion above the carrier plate. When the workpiece is at the discharge portion, it falls down by itself and passes through the detection area of ​​the frame-type counting sensor. At this time, the frame-type counting sensor detects the presence of the workpiece and completes a count. The control panel displays the accumulated count value in real time.

[0019] S104: The inspected workpieces are guided by the discharge section to the rear belt conveyor until all the workpieces in the storage area in the circular enclosure and the carrier plate are transferred through the turntable and counted by the frame-type counting sensor. After the counting is completed, the reduction motor is turned off.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the counting device and counting method applied to electrical automation are provided with a reduction motor, a front belt conveyor, an annular enclosure, a carrying plate, a discharge part, a gear-type belt composite transmission structure, a worm gear rotary table and a turntable and other structures that cooperate with each other. The reduction motor and the front belt conveyor send the annular sheet workpiece into the storage area formed by the annular enclosure and the carrying plate, and the worm gear rotary table receives the rotational power from the front belt conveyor through the gear-type belt composite transmission structure, so that the turntable uses the through hole to transfer the annular sheet workpiece to the discharge part of the carrying plate, the annular sheet workpiece falls through the discharge part and passes through the frame-type counting sensor, and the counted annular sheet workpiece continues to be sent out by the rear belt conveyor, so as to avoid the workpieces being densely arranged in a flat posture, and only one annular sheet workpiece passes through the frame-type counting sensor at a time, thereby optimizing the workpiece arrangement, improving the detection accuracy and reducing the missed detection error.

[0021] The annular sheet workpieces are sent to the storage area through the reduction motor and the front belt conveyor, and the workpieces are temporarily stored in a centralized manner using the structure of the annular enclosure and the carrier plate. Under the action of the worm gear rotary table, the workpieces are transferred one by one to the discharge part, so that the workpieces are formed into a single and separated state before being inspected, thereby significantly reducing the stacking density of the workpieces and ensuring that only one workpiece passes through the detection area of ​​the frame-type counting sensor at a time, avoiding the inspection difficulties caused by the dense arrangement of workpieces from the source, and through the gear-type belt composite transmission structure, the worm gear rotary table can rotate evenly at a lower speed, transferring the workpieces one by one to the discharge part, ensuring that each workpiece is When passing through the frame-type counting sensor, the workpiece is in a relatively fixed and stable position. The stable workpiece posture and position help the sensor accurately identify the presence of the workpiece, reducing detection errors caused by workpiece offset, rotation, or different positions. In addition, a nesting method is adopted to separate the workpieces one by one and pass them through the frame-type counting sensor individually, so that the sensor only detects one workpiece at a time. This "single-piece detection" strategy greatly reduces the probability of missed detection caused by multiple workpieces blocking the sensor at the same time, and also avoids misjudgment caused by multiple workpieces passing at the same time. At the same time, the frame-type counting sensor design can accurately detect the blocked area of ​​a single workpiece, further improving counting accuracy.

[0022] Secondly, the workpieces are separated one by one by mechanical means to ensure that only a single workpiece exists in the detection area, which significantly reduces the workload of the sensor and the possibility of errors. By achieving orderly flow and automatic separation of workpieces, the problem of workpiece accumulation and blockage is effectively avoided, reducing dependence on operators, thereby shortening the detection cycle and improving overall production efficiency.

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] Embodiment 1, by Figures 1 to 4 The present invention includes a horizontal I-shaped frame 1, a side frame 101 is fixed on the outer wall of one side of the horizontal I-shaped frame 1, and a front belt conveyor 2 and a rear belt conveyor 6 are respectively installed on the top of the horizontal I-shaped frame 1 and the side frame 101. A reduction motor 3 for driving the front belt conveyor 2 is installed on one side of the surface of the horizontal I-shaped frame 1, and a worm gear rotating platform 7 is installed on the outer wall of the horizontal I-shaped frame 1 above the rear belt conveyor 6. A turntable 12 is installed on the top of the output shaft of the worm gear rotating platform 7, and an annular enclosure 5 is fixed on the outer wall of the horizontal I-shaped frame 1 above the turntable 12. The annular enclosure 5 serves as a guide structure, surrounding the outer periphery of the turntable 12, limiting the movement range of the workpiece in the storage area, and preventing it from being scattered to non-target areas due to inertia or vibration, and the carrying plate 8 is located below the turntable 12 and does not rotate, thereby realizing the transition from disordered feeding to orderly temporary storage;

[0034] A carrying plate 8 is fixed to the top of the worm gear rotating platform 7 below the turntable 12, and a discharge portion 801 is provided at one edge position of the bottom end of the carrying plate 8. A frame-type counting sensor 9 is installed at the bottom end of the carrying plate 8 below the discharge portion 801. A plurality of through holes 1201 in an annular array with equal spacing are opened inside the turntable 12, and a height-adjustable material blocking component 11 is installed on the outer wall of the annular enclosure 5;

[0035] The discharge portion 801 is located at the edge of the carrier plate 8. When the discharge portion 801 and the through hole 1201 overlap, the workpiece can be released and guided to the detection area of ​​the frame-type counting sensor 9. By limiting the workpiece's falling path, the workpiece is forced to pass through the detection area in a vertical posture, maximizing the effective triggering area of ​​the sensor.

[0036] The gear-type belt composite transmission structure 13 is arranged on the other side of the surface of the horizontal I-frame 1, and is used to transmit the rotational power of the front belt conveyor 2 to the worm gear rotating table 7 and the rear belt conveyor 6. A control panel 4 electrically connected to the input end of the reduction motor 3 and the height-adjustable material resistance component 11 is installed on one side of the surface of the horizontal I-frame 1, and the output end of the frame-type counting sensor 9 is electrically connected to the input end of the control panel 4.

[0037] A counting method applied to electrical automation in this embodiment, such as the above-mentioned counting device applied to electrical automation, includes the following steps:

[0038] S101: Start the device through the control panel 4 to conduct a no-load test run to observe whether the turntable 12 rotates smoothly and whether the alignment period of the discharge portion 801 and the through hole 1201 is consistent. At the same time, start the height-adjustable material blocking assembly 11 through the control panel 4 so that the movable end of the height-adjustable material blocking assembly 11 contacts the upper surface of the turntable 12;

[0039] S102: The staff sets the speed of the reduction motor 3 on the control panel 4 according to the workpiece specifications. The speed of the turntable 12 must match the feeding rate of the front belt conveyor 2 to ensure that the workpiece accumulation in the storage area formed by the annular enclosure 5 and the carrier plate 8 is appropriate. The annular sheet workpieces are placed in batches at the starting end of the front belt conveyor 2, and the reduction motor 3 is started at a low speed. The workpieces are smoothly fed into the storage area formed by the annular enclosure 5 and the carrier plate 8 via the front belt conveyor 2;

[0040] S103: The front belt conveyor 2 transmits the rotational power to the worm gear rotary table 7 and the rear belt conveyor 6 through the gear-belt composite transmission structure 13, and the worm gear rotary table 7 drives the turntable 12 to rotate. A single workpiece falls into the through hole 1201 and is transferred with the turntable 12 to the top of the discharge portion 801 of the carrier plate 8. When the workpiece is located at the discharge portion 801, it falls down by itself and passes through the detection area of ​​the frame-type counting sensor 9. At this time, the frame-type counting sensor 9 detects the presence of the workpiece and completes a count. The control panel 4 displays the accumulated count value in real time.

[0041] S104: The inspected workpieces are guided by the discharge section 801 to the rear belt conveyor 6 until all the workpieces in the storage area of ​​the annular enclosure 5 and the carrier plate 8 are transferred via the turntable 12 and counted by the frame-type counting sensor 9. After the counting is completed, the reduction motor 3 is turned off.

[0042] Example 2, based on Example 1, Figure 5 、 Figure 6 and Figure 7 The front belt conveyor 2 includes a main shaft 201, a secondary shaft 202, and pulleys 203 fixed at one end of the main shaft 201 and the secondary shaft 202, which are rotatably mounted on both sides of the top of the horizontal I-frame 1. A conveyor belt 204 is set between the two pulleys 203. The output shaft of the reduction motor 3 is fixedly connected to one end of the main shaft 201.

[0043] The top of the horizontal I-shaped frame 1 on both sides of the conveyor belt 204 is bolted with a guide bar 205, a gap is provided between the two guide bars 205, the lower surface of the guide bar 205 is in contact with the upper surface of the conveyor belt 204, and the end of the guide bar 205 close to the annular enclosure 5 is provided with a bent portion. The driving shaft of the reduction motor 3 drives the main shaft 201 to rotate, and then the main shaft 201 and the secondary shaft 202 drive the conveyor belt 204 to move the workpiece through the pulley 203. In this process, a channel for the workpiece to pass is formed between the two guide bars 205, so as to ensure that the workpieces are neatly arranged in a flat posture, avoid posture deviation caused by sliding or collision, and smoothly convey the scattered annular workpieces to the storage area at the annular enclosure 5 and the carrying plate 8 through uniform motion;

[0044] The height-adjustable material blocking assembly 11 includes a circular frame 1101 fixed to the front and rear outer walls of the annular enclosure 5, a top plate 1102 fixed between the two circular frames 1101, and a screw electric lifting module 1103 installed inside one of the circular frames 1101. The movable end of the screw electric lifting module 1103 is equipped with two symmetrical material blocking arms 1104, which are located below the bent portion of the guide strip 205. The front and rear outer walls of the annular enclosure 5 are both provided with rectangular recesses 10 for the material blocking arms 1104 to slide along the Z axis.

[0045] In order to prevent the workpiece that has not entered the through hole 1201 from being rotated to the discharge section 801, the staff uses the height-adjustable material blocking component 11 to exclude this part of the non-hole workpiece. At this time, the staff turns on the screw electric lifting module 1103 through the control panel 4 to work, and uses the screw electric lifting module 1103 to drive the blocking arm 1104 to move downward until the lower surface of the blocking arm 1104 contacts the upper surface of the turntable 12. At this time, the non-hole workpiece on the upper surface of the turntable 12 cannot be moved due to the obstruction of the blocking arm 1104, while the workpiece in the through hole 1201 can be transferred to the discharge section 801 under the rotation of the turntable 12.

[0046] Example 3, based on Example 2, Figure 8 It is given that the worm gear rotating platform 7 includes a casing fixed on the outer wall of one side of the horizontal I-frame 1, a vertical shaft rotatably installed at the center position inside the casing, and a worm shaft rotatably installed on one side of the casing. One end of the vertical shaft surface is fixed with a worm wheel disk that meshes with the worm shaft. The top of the vertical shaft passes through the outside of the casing and is fixedly connected to the center position of the bottom end of the turntable 12. The carrying plate 8 is fixed to the top of the casing. One end of the worm shaft passes through the outside of the casing and is powered by the front belt conveyor 2 and the rear belt conveyor 6 through the gear-belt composite transmission structure 13.

[0047] The gear-belt composite transmission structure 13 includes a first gear shaft 1301, a second gear shaft 1303, and a third gear 1304 fixed to one end of the worm shaft, which are rotatably mounted on one side of the surface of the horizontal I-frame 1. The first gear shaft 1301, the second gear shaft 1303, and the third gear 1304 are meshed in sequence. A front belt transmission structure 1302 for driving the first gear shaft 1301 to rotate is installed at one end of the secondary shaft 202. The gear-belt composite transmission structure 13 converts the rotational power of the front belt conveyor 2 into the rotational motion of the worm gear rotating platform 7 to provide stable torque output. In this process, the secondary shaft 202 drives the first gear shaft 1301 through the front belt transmission structure 1302, and then the first gear shaft 1301 drives the third gear 1304 to rotate through the second gear shaft 1303. The third gear 1304 drives the input shaft of the worm gear rotating platform 7 to rotate, so that the turntable 12 rotates under the drive of the worm gear rotating platform 7.

[0048] The worm shaft of the worm gear rotating platform 7 rotates under the drive of the third gear 1304, and then the vertical shaft in the housing is driven by the worm shaft to rotate through the worm gear plate, and the vertical shaft drives the turntable 12 to rotate. The self-locking feature of the worm gear rotating platform 7 prevents the turntable 12 from shifting due to the gravity or vibration of the workpiece when it is stationary.

[0049] A rear belt transmission structure 1305 for power transmission is installed between one end of the worm shaft and the rear belt conveyor 6. The worm shaft of the worm gear rotating table 7 also drives the rear belt conveyor 6 through the rear belt transmission structure 1305, so that the rear belt conveyor 6 can continuously deliver the fallen workpiece.

[0050] When using the embodiment of the present application, first confirm that the power connection of the control panel 4 is normal, all buttons, display screens and indicator lights are working properly, check the operating status of the reduction motor 3 to ensure that it is well lubricated and there is no abnormal noise, then check whether the belts of the front belt conveyor 2 and the rear belt conveyor 6 are flat and tight, whether the transmission structure is intact, and whether the annular enclosure 5, the carrier plate 8, the gear-type belt composite transmission structure 13, the worm gear rotating table 7, and the turntable 12 are not loose, deformed or stuck. After completing the device inspection, turn on the device through the control panel 4 for a no-load test run, and observe whether the turntable 12 rotates smoothly and whether the discharge part 801 is in contact with the through hole. Whether the alignment periodicity of 1201 is consistent, and at the same time, the height-adjustable material resistance component 11 is turned on through the control panel 4, so that the movable end of the height-adjustable material resistance component 11 can contact the upper surface of the turntable 12; the staff sets the speed of the reduction motor 3 on the control panel 4 according to the specifications of the workpiece, the conveying speed of the front belt conveyor 2, the rear belt conveyor 6, the rotation speed of the turntable 12 and the speed of the reduction motor 3 are proportional. At this time, the speed of the turntable 12 needs to match the feeding rate of the front belt conveyor 2 to ensure that the amount of workpieces accumulated in the storage area formed by the annular enclosure 5 and the carrier plate 8 is moderate, and the turntable 12 will not be stuck due to too fast feeding, and The turntable 12 will not idle due to insufficient feeding; the staff will place the annular sheet workpieces in batches at the starting end of the front belt conveyor 2, start the reduction motor 3 to run at a low speed, and the workpieces will be smoothly sent into the storage area formed by the annular enclosure 5 and the carrying plate 8 through the front belt conveyor 2; the front belt conveyor 2 transmits the rotational power to the worm gear rotating table 7 and the rear belt conveyor 6 through the gear belt composite transmission structure 13, and the worm gear rotating table 7 drives the turntable 12 to rotate, and a single workpiece falls into the through hole 1201 and is transferred with the turntable 12 to the top of the discharge part 801 of the carrying plate 8. When the workpiece is at the discharge part 801, it falls down by itself and passes through the frame-type The detection area of ​​the counting sensor 9, at this time the frame-type counting sensor 9 detects the presence of the workpiece and completes a count, and the control panel 4 displays the accumulated count value in real time; the detected workpiece is guided by the discharge part 801 to the rear belt conveyor 6, until all the workpieces in the storage area of ​​the annular enclosure 5 and the carrying plate 8 are transferred through the turntable 12 and counted by the frame-type counting sensor 9. After the counting is completed, the reduction motor 3 is turned off, and the control panel 4 displays the final count value; after confirming that there are no residual workpieces on the rear belt conveyor 6, the device is turned off, and the turntable 12, the carrying plate 8, and the frame-type counting sensor 9 are cleaned and maintained to prevent oil or debris from affecting subsequent operations.
