Description

Technical Field

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

[0002] The ring-shaped sheet workpiece conveying and counting device based on electrical automation is used to realize the continuous automatic conveying and accurate counting of workpieces, so as to improve production efficiency, ensure product quality, reduce human error, and realize the intelligent management of the production process. This device consists of a conveying track or conveyor belt, sensors, a control unit, and a display or storage device. The ring track design helps to achieve the continuous cyclic conveying of workpieces. Sensors (such as photoelectric or proximity sensors) are responsible for detecting the arrival and departure of workpieces. After receiving the signal, the control unit (usually a PLC or an industrial computer) automatically updates the count value and controls relevant mechanical actions. The whole process is as follows: when a workpiece passes by the sensor, the signal is transmitted to the control system, and the system automatically increases the count, ensuring that each workpiece is accurately counted and avoiding the error of 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 ring-shaped sheet workpieces are basically in a lying state, and their shape is similar to a flat ring or disc. Due to their structural characteristics, the surface area of the workpieces is large and the thickness is relatively thin. When the ring-shaped sheet workpieces are densely arranged in a lying posture, the edge spacing between adjacent workpieces is extremely small or even partially overlapped, resulting in the detection area of the sensor 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 workpieces or be reflected by adjacent workpieces, forming a "continuous signal coverage area". The device cannot effectively distinguish the passing events of individual workpieces. For example, when the spacing between workpieces 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 recognize two workpiece passes as a single trigger, resulting in missed detection and misdetection phenomena. Summary of the Invention

[0003] The purpose of the present invention is to provide a counting device and a counting method applied to electrical automation. A speed reduction motor and a front belt conveyor send the ring-shaped sheet workpieces into the storage area formed by the ring-shaped enclosure and the bearing plate. And the worm and worm gear rotating table receives the rotating power from the front belt conveyor through a gear-type belt composite transmission structure, so that the turntable transfers the ring-shaped sheet workpieces to the discharging part of the bearing plate by using through holes. The ring-shaped sheet workpieces fall through the discharging part and pass through the frame-type counting sensor. After being counted, the ring-shaped sheet workpieces continue to be sent out by the rear belt conveyor, so as to solve the problems raised in the above background technique.

A control panel electrically connected to the input ends of the reduction motor and the height-adjustable material blocking assembly is installed on one side of the surface of the horizontal I-shaped frame, and the output end of the frame-shaped counting sensor is electrically connected to the input end of the control panel.

[0005] Preferably, the front belt conveyor includes a main shaft and a sub-shaft rotatably installed on both sides of the top end of the horizontal I-shaped frame, and belt pulleys fixed at one ends of the surfaces of the main shaft and the sub-shaft. A conveyor belt is sleeved between the two belt pulleys, and the output shaft of the reduction motor is fixedly connected to one end of the main shaft.

[0006] Preferably, guide strips are bolted and installed at the top ends of the horizontal I-shaped frame on both sides of the conveyor belt. A gap part is arranged between the two guide strips, and the lower surface of the guide strip is in contact with the upper surface of the conveyor belt.

[0007] Preferably, a bent part is arranged at one end of the guide strip close to the annular enclosure.

[0008] Preferably, the height-adjustable material blocking assembly includes a return-shaped frame fixed on the front and rear outer walls of the annular enclosure, a top plate fixed between the two return-shaped frames, and a screw rod electric lifting module installed inside one of the return-shaped frames. Two symmetrical material blocking arms are installed at the moving end of the screw rod electric lifting module, and the material blocking arms are located below the bent part of the guide strip.

[0009] Preferably, rectangular concave parts for the material blocking arms to perform Z-axis sliding are arranged on the front and rear outer walls of the annular enclosure.

[0010] Preferably, the worm and worm gear rotary table includes a casing fixed to the outer wall of one side of the horizontal I-shaped frame, a vertical shaft rotatably installed at the central position inside the casing, and a worm shaft rotatably installed at one side inside the casing. One end of the surface of the vertical shaft is fixed with a worm gear disk meshing with the worm shaft. The top end of the vertical shaft penetrates to the outside of the casing and is fixedly connected to the center position at the bottom end of the turntable. The bearing disk is fixed to the top end of the casing. One end of the worm shaft penetrates to the outside of the casing and is power-connected to the front belt conveyor and the rear belt conveyor through a gear-type belt composite transmission structure.

[0011] Preferably, the gear-type belt composite transmission structure includes a first gear shaft, a second gear shaft rotatably installed on one side of the surface of the horizontal I-shaped frame, and a third gear fixed to one end of the worm shaft.

One end of the auxiliary shaft is equipped with a front belt transmission structure for driving the first gear shaft to rotate.

[0012] Preferably, a rear belt transmission structure for power transmission is installed between one end of the worm shaft and the rear belt conveyor.

[0013] The present invention also provides a counting method applied to electrical automation. For the counting device applied to electrical automation as described above, it includes the following steps: S101: Turn on the device through the control panel for no-load trial operation. Observe whether the turntable rotates smoothly and whether the alignment periodicity between the discharging part and the through hole is consistent. At the same time, turn on the height-adjustable material blocking component through the control panel to make the movable end of the height-adjustable material blocking component contact the upper surface of the turntable. S102: The staff sets the rotation speed of the reduction motor on the control panel according to the workpiece specifications. The rotation speed of the turntable needs to match the feeding rate of the front belt conveyor to ensure that the workpiece accumulation amount in the storage area formed by the annular enclosure and the bearing disk is appropriate. Place the annular sheet-shaped workpieces in batches at the starting end of the front belt conveyor, and start the reduction motor to run at a low speed. The workpieces are smoothly fed into the storage area formed by the annular enclosure and the bearing disk through the front belt conveyor. S103: The front belt conveyor transmits the rotary power to the worm and worm gear rotary table and the rear belt conveyor through the gear-type belt composite transmission structure. Then the worm and worm gear rotary table drives the turntable to rotate. A single workpiece falls into the through hole and is transferred to the upper part of the discharging part of the bearing disk along with the turntable. When the workpiece is at the discharging part, it falls 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 one counting. The control panel displays the cumulative count value in real time. S104: The detected workpieces are guided to the rear belt conveyor by the discharging part until all the workpieces in the storage area of the annular enclosure and the bearing disk are transferred by the turntable and counted by the frame-type counting sensor. After the counting is completed, turn off the reduction motor.

[0014] 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 rotating 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 rotating table receives the rotational power from the front belt conveyor through the gear-type belt composite transmission structure, so that the turntable transfers the annular sheet workpiece to the discharge part of the carrying plate through the through hole, and the annular sheet workpiece falls through the discharge part and passes through the frame-type counting sensor. 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 lying 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.

[0015] 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 by 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 detected, thereby significantly reducing the stacking density of the workpieces, ensuring that only one workpiece passes through the detection area of ​​the frame-type counting sensor at a time, avoiding the detection 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, and transfer the workpieces one by one to the discharge part, ensuring that each workpiece passes through the detection area of ​​the frame-type counting sensor at a time. 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 to accurately identify the presence of the workpiece, reduce the detection error caused by the offset, rotation or position of the workpiece, and adopt the nesting method to separate the workpieces one by one and pass 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 the misjudgment caused by multiple workpieces passing at the same time. At the same time, the frame-type counting sensor design can accurately detect the blocking area of ​​a single workpiece, further improving the counting accuracy; Secondly, the workpieces are separated one by one by mechanical means to ensure that there is only a single workpiece 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.

Specific embodiments

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Embodiment 1, consisting of Figures 1 to 4Given that, 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. A front belt conveyor 2 and a rear belt conveyor 6 are respectively installed at the tops of the horizontal I-shaped frame 1 and the side frame 101. A reduction motor 3 for driving the front belt conveyor 2 to work is installed on one side of the surface of the horizontal I-shaped frame 1. A worm and gear rotary table 7 is installed on the outer wall of the horizontal I-shaped frame 1 above the rear belt conveyor 6. The top end of the output shaft of the worm and gear rotary table 7 is installed with a turntable 12. 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 guiding structure and surrounds the periphery of the turntable 12, restricting the movement range of the workpiece in the storage area and preventing it from scattering to non-target areas due to inertia or vibration. And the bearing plate 8 is located below the turntable 12 and does not rotate, realizing the transition from disordered feeding to ordered temporary storage; A bearing plate 8 is fixed at the top end of the worm and gear rotary table 7 below the turntable 12. A discharge part 801 is arranged at one side edge position of the bottom end of the bearing plate 8. A frame-shaped counting sensor 9 is installed at the bottom end of the bearing plate 8 below the discharge part 801. A plurality of through holes 1201 arranged in an annular and equally spaced array are formed inside the turntable 12. A height-adjustable material blocking component 11 is installed on the outer wall of the annular enclosure 5; The discharge part 801 is located at the edge of the bearing plate 8. When the discharge part 801 and the through hole 1201 coincide, the releasable workpiece can be released and guided to the detection area of the frame-shaped counting sensor 9. By restricting the falling path of the workpiece, the workpiece is forced to pass through the detection area in a vertical posture, maximizing the effective triggering area of the sensor; A gear-type belt composite transmission structure 13 is arranged on the other side of the surface of the horizontal I-shaped frame 1, and is used to transmit the rotary power of the front belt conveyor 2 to the worm and gear rotary table 7 and the rear belt conveyor 6. A control panel 4 electrically connected to the input ends of the reduction motor 3 and the height-adjustable material blocking component 11 is installed on one side of the surface of the horizontal I-shaped frame 1. The output end of the frame-shaped counting sensor 9 is electrically connected to the input end of the control panel 4.

[0020] A counting method applied to electrical automation in this embodiment, such as the counting device applied to electrical automation described above, includes the following steps: S101: Turn on the device through the control panel 4 for no-load trial operation, observe whether the rotation of the turntable 12 is stable and whether the periodic alignment of the discharge part 801 and the through hole 1201 is consistent. At the same time, turn on the height-adjustable material blocking component 11 to work through the control panel 4 so that the movable end of the height-adjustable material blocking component 11 contacts the upper surface of the turntable 12; S102: The operator sets the rotation speed of the reduction motor 3 on the control panel 4 according to the workpiece specifications. The rotation speed of the turntable 12 needs to match the feeding rate of the front belt conveyor 2 to ensure an appropriate accumulation of workpieces in the storage area formed by the annular enclosure 5 and the bearing plate 8. Place a batch of annular sheet workpieces at the starting end of the front belt conveyor 2, and start the reduction motor 3 to run at a low speed. The workpieces are smoothly fed into the storage area formed by the annular enclosure 5 and the bearing plate 8 through the front belt conveyor 2; S103: The front belt conveyor 2 transmits the rotation power to the worm and gear rotating table 7 and the rear belt conveyor 6 through the gear-type belt composite transmission structure 13. Then, the worm and gear rotating table 7 drives the turntable 12 to rotate. A single workpiece falls into the through hole 1201 and is transferred with the turntable 12 above the discharging part 801 of the bearing plate 8. When the workpiece is at the discharging part 801, it falls 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 one count, and the control panel 4 displays the cumulative count value in real time; S104: The detected workpieces are guided by the discharging part 801 onto the rear belt conveyor 6 until all the workpieces in the storage area in the annular enclosure 5 and the bearing plate 8 are transferred by the turntable 12 and counted by the frame-type counting sensor 9. After the counting is completed, the reduction motor 3 is turned off.

[0021] Embodiment 2 is based on Embodiment 1 and is given by Figure 5 、 Figure 6 and Figure 7 The front belt conveyor 2 includes a main shaft 201 and a sub-shaft 202 rotatably installed on both sides of the top end of the horizontal I-shaped frame 1, and belt pulleys 203 fixed to one ends of the surfaces of the main shaft 201 and the sub-shaft 202. A conveyor belt 204 is sleeved between the two belt pulleys 203, and the output shaft of the reduction motor 3 is fixedly connected to one end of the main shaft 201; Guide strips 205 are bolted and installed at the top ends of the horizontal I-shaped frames 1 on both sides of the conveyor belt 204. A gap part is provided between the two guide strips 205. The lower surface of the guide strip 205 is in contact with the upper surface of the conveyor belt 204. The end of the guide strip 205 close to the annular enclosure 5 is provided with a bent part. The driving shaft of the reduction motor 3 drives the main shaft 201 to rotate, and then the main shaft 201 and the sub-shaft 202 drive the conveyor belt 204 to move the workpiece by means of the belt pulleys 203. During this process, a passage for the workpiece to pass through is formed between the two guide strips 205, so as to ensure that the workpieces are neatly arranged in a lying 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 bearing plate 8 through uniform motion; The height-adjustable material blocking assembly 11 includes a U-shaped frame 1101 fixed on the front and rear outer walls of the annular enclosure 5, a top plate 1102 fixed between the two U-shaped frames 1101, and a screw rod electric lifting module 1103 installed inside one of the U-shaped frames 1101. Two symmetrical material blocking arms 1104 are installed on the moving end of the screw rod electric lifting module 1103. The material blocking arms 1104 are located below the bent part of the material guiding strip 205. Rectangular concave parts 10 for the Z-axis sliding of the material blocking arms 1104 are provided on the front and rear outer walls of the annular enclosure 5. In order to prevent the workpieces that have not entered the through holes 1201 from being rotated to the discharging part 801, the staff uses the height-adjustable material blocking assembly 11 to remove these non-hole inner workpieces. At this time, the staff turns on the screw rod electric lifting module 1103 through the control panel 4 to work, and uses the screw rod electric lifting module 1103 to drive the material blocking arms 1104 to move downward until the lower surface of the material blocking arms 1104 contacts the upper surface of the turntable 12. At this time, the non-hole inner workpieces on the upper surface of the turntable 12 are blocked by the material blocking arms 1104 and cannot move, while the workpieces in the through holes 1201 can be transferred to the discharging part 801 under the rotation of the turntable 12.

[0022] Embodiment 3, on the basis of Embodiment 2, is given by Figure 8 The worm and gear rotating table 7 includes a machine shell fixed on the outer wall of one side of the horizontal I-shaped frame 1, a vertical shaft rotatably installed at the central position inside the machine shell, and a worm shaft rotatably installed on one side inside the machine shell. One end of the surface of the vertical shaft is fixed with a worm wheel disk meshing with the worm shaft. The top end of the vertical shaft penetrates to the outside of the machine shell and is fixedly connected to the bottom central position of the turntable 12. The bearing plate 8 is fixed on the top of the machine shell. One end of the worm shaft penetrates to the outside of the machine shell and is power-connected to the front belt conveyor 2 and the rear belt conveyor 6 through a gear-type belt composite transmission structure 13. The gear-type belt composite transmission structure 13 includes a first gear shaft 1301, a second gear shaft 1303 rotatably installed on one side of the surface of the horizontal I-shaped frame 1, and a third gear 1304 fixed at one end of the worm shaft. The first gear shaft 1301, the second gear shaft 1303, and the third gear 1304 are meshed in sequence. One end of the auxiliary shaft 202 is installed with a front belt transmission structure 1302 for driving the first gear shaft 1301 to rotate. The gear-type belt composite transmission structure 13 converts the rotary power of the front belt conveyor 2 into the rotary motion of the worm and gear rotating table 7 to provide stable torque output. In this process, the auxiliary shaft 202 drives the first gear shaft 1301 through the front belt transmission structure 1302. Then, the first gear shaft 1301 drives the third gear 1304 to rotate through the second gear shaft 1303. The input shaft of the worm and gear rotating table 7 is driven by the third gear 1304 to rotate, so that the turntable 12 rotates self-driven under the drive of the worm and gear rotating table 7. The worm shaft of the worm and worm gear rotary table 7 rotates under the drive of the third gear 1304. Subsequently, the vertical shaft in the machine housing is driven to rotate by the worm shaft through the worm gear disk, and the rotary table 12 rotates self-driven by the vertical shaft. The self-locking characteristic of the worm and worm gear rotary table 7 prevents the rotary table 12 from shifting due to the workpiece gravity or vibration in the stationary state; A rear belt drive 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 and worm gear rotary table 7 also drives the rear belt conveyor 6 to work through the rear belt drive structure 1305, so that the rear belt conveyor 6 continuously sends out the fallen workpieces.

[0023] When the embodiment of the present application is in use, 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, and whether the transmission structure is intact. There is no looseness, deformation or jamming in the annular enclosure 5, the bearing plate 8, the gear-shaped belt composite transmission structure 13, the worm and worm gear rotating table 7, and the turntable 12. After the device inspection is completed, start the device through the control panel 4 for no-load commissioning, observe whether the rotation of the turntable 12 is stable and whether the periodic alignment of the discharging part 801 and the through hole 1201 is consistent. At the same time, start the height-adjustable material blocking component 11 through the control panel 4 so that the movable end of the height-adjustable material blocking component 11 touches the upper surface of the turntable 12; the staff sets the rotation speed of the reduction motor 3 on the control panel 4 according to the workpiece specifications. The conveying speeds of the front belt conveyor 2 and the rear belt conveyor 6 and the rotation speed of the turntable 12 are proportional to the rotation speed of the reduction motor 3. At this time, the rotation speed of the turntable 12 needs to match the feeding rate of the front belt conveyor 2 to ensure that the workpiece accumulation amount in the material storage area formed by the annular enclosure 5 and the bearing plate 8 is appropriate, neither causing the turntable 12 to jam due to excessive feeding nor causing the turntable 12 to rotate idly due to insufficient feeding; the staff places a batch of annular sheet workpieces at the starting end of the front belt conveyor 2 and starts the reduction motor 3 to run at a low speed. The workpieces are smoothly fed into the material storage area formed by the annular enclosure 5 and the bearing plate 8 through the front belt conveyor 2; the front belt conveyor 2 transmits the rotary power to the worm and worm gear rotating table 7 and the rear belt conveyor 6 through the gear-shaped belt composite transmission structure 13. Then the worm and worm gear rotating table 7 drives the turntable 12 to rotate. A single workpiece falls into the through hole 1201 and is transferred to the upper part of the discharging part 801 of the bearing plate 8 along with the turntable 12. When the workpiece is at the discharging part 801, it falls by itself and passes through the detection area of the frame-shaped counting sensor 9. At this time, the frame-shaped counting sensor 9 detects the presence of the workpiece and completes one counting, and the control panel 4 displays the cumulative count value in real time; the inspected workpieces are guided to the rear belt conveyor 6 by the discharging part 801 until all the workpieces in the material storage area in the annular enclosure 5 and the bearing plate 8 are transferred by the turntable 12 and counted by the frame-shaped counting sensor 9. After the counting is completed, turn off the reduction motor 3. At this time, the control panel 4 displays the final count value; after confirming that there are no residual workpieces on the rear belt conveyor 6, turn off the device and clean and maintain the turntable 12, the bearing plate 8, and the frame-shaped counting sensor 9 to prevent oil stains or debris from affecting subsequent operation.

10. A counting method applied to electrical automation, which is applied to a counting device for electrical automation according to any one of claims 1-9, characterized in that: It includes the following steps: S101: Turn on the device through the control panel (4) for no-load trial operation. Observe whether the turntable (12) rotates smoothly and whether the periodic alignment of the discharging part (801) and the through hole (1201) is consistent. At the same time, turn on 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) can contact the upper surface of the turntable (12). S102: The staff sets the rotation speed of the reduction motor (3) on the control panel (4) according to the workpiece specifications. The rotation speed of the turntable (12) needs to match the feeding rate of the front belt conveyor (2) to ensure that the workpiece accumulation amount in the storage area formed by the annular enclosure (5) and the bearing plate (8) is appropriate. Place the annular sheet workpieces in batches at the starting end of the front belt conveyor (2), and start the reduction motor (3) to run at a low speed. The workpieces are smoothly fed into the storage area formed by the annular enclosure (5) and the bearing plate (8) through the front belt conveyor (2). S103: The front belt conveyor (2) transmits the rotary power to the worm and worm gear rotary table (7) and the rear belt conveyor (6) through the gear type belt composite drive structure (13). Then the worm and worm gear rotary table (7) drives the turntable (12) to rotate. A single workpiece falls into the through hole (1201) and is transferred to the upper part of the discharging part (801) of the bearing plate (8) along with the turntable (12). When the workpiece is at the discharging part (801), it falls by itself and passes through the detection area of the frame type counting sensor (9).
