Description

Technical Field

[0001] The invention relates to the technical field of automatic packaging equipment, in particular to a rotary material feeding counting device. Background Art

[0002] At present, toys that can be assembled (mainly building blocks and other splicing toys) have many types of parts and different quantities of different parts. Therefore, in order to meet the needs of large-scale industrial production, the packaging production line of toy parts needs to set up a counting and sorting mechanism for each part for subsequent packaging. In the past, most toy packaging loading methods used a single unloading or conveyor track working method, which had low work efficiency, low pass rate, low equipment accuracy, low stability, long maintenance time, inconvenient installation and debugging, and the counting method logic was not rigorous enough, which was prone to misjudgment. Summary of the invention

[0003] The present invention aims at the technical problems existing in the prior art and provides a rotary feeding counting device to solve the problem that most toy packaging feeding methods adopt a single feeding or conveying track working mode, which has low working efficiency, low qualified rate, low equipment precision, low stability, long maintenance time, inconvenient installation and debugging, and the counting method logic is not rigorous enough, which is prone to misjudgment.

[0005] The material falls into the feeding port of the unloading chute and triggers the signal of the optical fiber sensor in turn. The optical fiber sensor counts the material. The material falls on the unloading chute and slides into the inner groove of the arc of the impeller by gravity. After counting to the target number, the motor of the equal-division drive structure rotates 90°, and drives the positioning ring, connecting sleeve and impeller of the equal-division drive structure to rotate together. After receiving the signal of the slot-type photoelectric, the motor stops rotating. The rotation angle is determined by the four-equal-division notches on the positioning ring and the slot-type photoelectric. The material is discharged from the discharge port of the discharge chute, and the optical fiber sensor at the discharge port of the discharge chute performs a secondary detection of the material; when the number of materials falling in exceeds the target number, the motor reverses 90° to discharge the material falling into the inner groove of the arc from the residual material discharge port. The impeller is divided into four parts, and there is no need to rotate after discharge, which reduces movement and improves efficiency.

[0040] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0041] The present invention provides the following preferred embodiments

[0042] See also Figure 1 , Figure 2 , Figure 4 and Figure 5The present embodiment provides a rotary material discharging counting device, which includes a material discharging tunnel 1000, which is divided into a material discharging chute 10, a material discharging chute 20, a transition section 30 and a residual material discharging port 40. The material discharging chute 20 intersects with the material discharging chute 10, and the material discharging chute 10 and the material discharging chute 20 form an angle, which can be set between 30° and 70° to ensure that the material can smoothly flow from the material discharging chute 10 to the material discharging chute 20 under the action of its own gravity. A counter-fiber sensor 50 is provided at the feed port of the material discharging chute 10 and the discharge port of the material discharging chute 20, and the number of materials falling in and out can be effectively counted by the counter-fiber sensor 50; the transition section 30 is provided at the intersection of the material discharging chute 10 and the material discharging chute 20, which plays a transition role and also provides space for subsequent material processing. The residual material discharge port 40 is connected to the transition section 30, ensuring that the residual material generated during the material calculation and processing process can be effectively discharged. A rotatable impeller 60 is provided inside the transition section 30. The impeller 60 is divided into four equal parts, and an arc inner groove 601 that can accommodate materials is formed between two adjacent blades. The outer side of the transition section 30 is also provided with an equal-division driving structure 70 that can drive the impeller 60 to rotate counterclockwise and clockwise. The angle of each rotation of the equal-division driving structure 70 is precisely set to 90°. This design enables the material in the arc inner groove 601 to face the unloading chute 10, the residual material discharge port 40 and the discharge chute 20 in turn, thereby realizing the orderly flow and accurate counting of materials. In addition, the discharge chute 20 is also provided with an accelerated impurity removal structure 80. The function of this structure is to speed up the falling speed of the material and effectively remove the impurities adsorbed on the surface of the material due to static electricity, thereby ensuring the purity of the material and the smoothness of the unloading process.

[0043] The main structure of the blanking tunnel 1000 in the embodiment of the present invention is surrounded by a paging side cover plate 1001, a track side cover plate 1002, a blocking observation plate 1003, and a plurality of track blocks 1004. The paging side cover plate 1001 and the track side cover plate 1002 are arranged in parallel with each other, and the blocking observation plate 1003 is arranged on the front side of the paging side cover plate 1001 and the track side cover plate 1002, wherein two track blocks 1004 are arranged on the paging side cover plate 1001 and the track side cover plate 1002 at both ends of the blocking observation plate 1003, and the other track blocks 1004 are arranged on the paging side cover plate 1001 and the track side cover plate 1002 at the two ends of the blocking observation plate 1003. The rear side of the page side cover plate 1001 and the track side cover plate 1002, and the interval between the two track blocks 1004 on the rear side form a residual material discharge port 40, one of the track blocks 1004 on the rear side is provided with an arc surface to facilitate the rotation of the impeller 60, and the size of the residual material discharge port 40 is determined by the equal size of the impeller 60, thereby ensuring the accuracy of the discharge; specifically, the surface of one blade in the impeller 60 is flush with the bottom surface of the residual material discharge port 40, while the other blade serves to block the residual material discharge port 40, thereby preventing the material from flowing out when it should not be discharged.

[0044] Furthermore, in order to conveniently observe the material dropping situation inside the material dropping tunnel 1000 and observe whether there is material accumulation in the material dropping tunnel 1000, the track side cover plate 1002 is made of transparent acrylic. The operator observes the material dropping situation through the transparent acrylic plate, understands the operation of the equipment structure, observes the wear and tear of parts, and facilitates maintenance. In addition, the paging side cover plate 1001 and the track side cover plate 1002 are integrally machined and formed, and the side of the paging side cover plate 1001 and the track side cover plate 1002 is provided with a sink that cooperates with the impeller 60, which reduces the gap step, can greatly reduce the gap problem caused by the structure and installation accuracy, and improve the material dropping efficiency.

[0045] In order to avoid the accumulation of materials on the unloading chute 10 during the production process, which leads to the inability to unload materials smoothly and the inability to ensure the accuracy of the packaging quantity, the blocking material observation plate 1003 is provided with an L-shaped connector 1005. One side of the blocking material observation plate 1003 can be detachably connected to the track side cover 1002 through the L-shaped connector 1005, and the other side is abutted against the paging side cover 1001. The staff can simply disassemble the blocking material observation plate 1003 to quickly clean up the accumulated materials, thereby ensuring the smooth progress of the production process and avoiding production stagnation caused by material accumulation.

[0046] In the embodiment of the present invention, the equally divided driving structure 70 is used to drive the impeller 60 to rotate 90° each time. In order to enable the equally divided driving structure 70 to drive the impeller 60 to rotate 90° accurately, please refer to Figure 3 and Figure 6The sub-drive structure includes a mounting seat, a motor, a positioning ring 701, a connecting sleeve 702, and a slot-type photoelectric 703. The mounting seat is fixed on the paging side cover 1001. The motor adopts a stepping motor, and the motor is installed on the mounting seat. The connecting sleeve 702 is connected to the output shaft of the motor. The central axis of the positioning ring 701 is hollow, matched with the outer diameter of the connecting sleeve 702, and fixed on the connecting sleeve 702 by a top screw, and the positioning ring 701 is divided into four equal parts along the circumferential direction and has slots 704; the slot-type photoelectric 703 is installed on the mounting seat through a right-angle sheet metal, and the slot 704 of the slot-type photoelectric 703 corresponds to the four-divided slot 704 of the positioning ring 701, which can determine the motor to rotate 90 degrees. Each slot 704 of the four-divided slot 704 corresponds to each blade of the sub-impeller 60. By setting the equally divided drive structure 70, the driving task of the sub-impeller 60 can be completed efficiently and stably, ensuring the reliability and accuracy of the entire system.

[0047] In an embodiment of the present invention, the design of the equally divided drive structure 70 not only considers the accuracy of rotation, but also the stability and reliability of the system. For this reason, the material selection and manufacturing process of the mounting seat are 6061 aluminum alloy, and are processed by CNC machining with high precision to ensure that it can maintain stable performance in various working environments. The motor is the driving core, and the use of its stepper motor ensures the high accuracy and repeatability of rotation, which is crucial for achieving precise control of the impeller 60. The design of the connecting sleeve 702 not only needs to ensure a firm connection with the motor output shaft, but also ensure that no unnecessary vibration or noise is generated during the rotation process. The design of the four-equally divided notch 704 of the positioning ring 701, combined with the precise detection of the slot-type photoelectric 703, enables each rotation to reach a predetermined 90 degrees, thereby ensuring the accurate position of the impeller 60 blades. In addition, the entire drive structure also includes necessary sealing and lubrication systems to reduce wear and extend the service life of the equipment.

[0048] For the main structure of the impeller 60 in the embodiment of the present invention, please refer to Figure 3 The central axis of the impeller 60 is hollow and is equipped with a pin 602. The central hole of the impeller 60 and the pin 602 are provided with keyways. The impeller 60 and the pin 602 are fixed with flat keys. Both ends of the pin 602 pass through the transition section 30 and are connected with seat bearings 603. One end of the pin 602 is connected to the connecting sleeve 702, and the connecting sleeve 702 is connected to the output shaft of the motor. The two seat bearings 603 are respectively fixed to the paging side cover 1001 and the track side cover 1002. The setting of the seat bearing 603 can support the pin 602, reduce wear, absorb vibration, and improve the running stability of the entire mechanical system.

[0049] Furthermore, an impeller side cover plate 604 is provided on the impeller 60 away from the side of the equally divided driving structure 70. The impeller side cover plate 604 is connected to the blades with screws so that the impeller 60 forms four semi-closed grooves for accommodating materials. The impeller side cover plate 604 is made of transparent acrylic, and the impeller 60 is machined as a whole to avoid the gap step problem and improve the material discharge efficiency.

[0050] In the embodiment of the present invention, the accelerated impurity removal structure 80 is mainly used to accelerate the falling speed of the material in the discharge chute 20, and to remove impurities adsorbed on the surface of the material due to static electricity. The accelerated impurity removal structure 80 includes a through hole provided on the material blockage observation plate 1003 and an air blowing pipe with one end passing through the through hole. The air blowing pipe is fixed to the material blockage observation plate 1003 through a fixing plate, and the air blowing pipe is connected to an external air source.

[0051] In summary, after the material falls from the feed port of the unloading chute 10, the signal of the opposite-beam optical fiber sensor 50 will be triggered in turn, and the opposite-beam optical fiber sensor 50 will count immediately, and the material will slide onto the unloading chute 10 by gravity, and finally fall into the circular arc inner groove 601 of the impeller 60; when the count reaches the preset target number, the motor in the equal-division drive structure 70 starts to rotate 90 degrees, and at the same time drives the positioning ring 701, the connecting sleeve 702 and the impeller 60 of the equal-division drive structure 70 to rotate together. After receiving the signal of the slot-type photoelectric sensor 703, the motor stops rotating, and the rotation angle is determined by the cooperation of the four-equal-division slot 704 on the positioning ring 701 and the slot-type photoelectric sensor 703; then, the material in the circular arc inner groove 601 falls into the discharge chute 20, and the material is discharged from the discharge port of the discharge chute 20, and the opposite-beam optical fiber sensor 50 at the discharge port of the discharge chute 20 performs secondary detection on the discharged material.

[0052] If the amount of material falling in exceeds the target amount, the motor will reverse 90 degrees, so that the excess material falling into the inner groove 601 of the arc can be discharged through the excess material discharge port 40. In this way, the rotary material discharge counting device of the present invention not only improves the efficiency of material processing, but also ensures the accuracy of material counting, and at the same time avoids material waste by timely discharging the excess material.

[0053] The beneficial effects of the present invention are mainly reflected in the following aspects:

[0054] First, the rotary material discharging counting device of the present invention realizes accurate counting and efficient material discharging through its unique design. Due to the quarter-divided design of the impeller 60, the device does not need to perform complex rotational movements during material discharging, thereby reducing mechanical wear and energy consumption and extending the service life of the equipment. In addition, the design of the circular arc inner groove 601 of the impeller 60 ensures the stability of the material during the discharging process and avoids the scattering or damage of the material during the discharging process.

[0055] Secondly, the device of the present invention realizes accurate management of the material discharge process through the precise control of the equally divided driving structure 70. The equally divided driving structure 70 rotates 90 degrees each time, which ensures the accuracy and consistency of material discharge and avoids material waste caused by improper operation. At the same time, the stability and reliability of the structure also greatly improve the working efficiency of the entire device.

[0056] Furthermore, the accelerated impurity removal structure 80 of the present invention effectively increases the falling speed of the material, reduces the residence time of the material in the slideway, and thus reduces the possibility of material contamination. At the same time, the structure can also remove impurities adsorbed on the surface of the material, ensuring the purity and quality of the material and meeting the requirements of high-precision production.

[0057] Finally, the design of the residual material discharge port 40 of the present invention provides a fast and effective discharge channel for materials exceeding the target quantity. This design not only avoids the waste of materials, but also ensures the continuity and stability of the production process, providing strong support for the realization of automated production.

[0058] In summary, the rotary material discharging counting device of the present invention not only improves the efficiency and accuracy of material processing through its innovative design and structure, but also ensures the quality of materials and the continuity of production. The device is suitable for various automated production lines, especially in occasions with strict requirements on material counting and discharging, and has broad application prospects.

[0059] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
