[0001] The present invention belongs to the field of pen refill packing, and particularly relates to an automatic counting device and method for pen refill packing. Background Art

[0002] In the production process of pencil refills, after the lead cores are fired and formed, they need to be packed into boxes. Currently, the packing method used in the industry is manual weighing and manual boxing, which requires a great deal of physical strength from the operators. There are problems of high labor intensity and inaccurate weighing in the existing packing process. Summary of the Invention

[0003] In view of this, the present invention aims to provide an automatic counting device and method for pen refill packing to solve the problems of high labor intensity and inaccurate weighing in the existing pen refill packing process.

[0004] To achieve the above object, the present invention adopts the following technical solutions: An automatic counting device for pen refill packing, which includes a pen refill hopper, a pen refill tray, a blanking core hopper, a middle box transportation chain, a middle box detection sensor, a laser detection sensor and a control system module. The upper end of the pen refill hopper is provided with a pen refill hopper feed port, and one side of the lower end is provided with a pen refill hopper discharge port. The number of the pen refill hoppers is two, and the two pen refill hoppers are horizontally symmetrically arranged. At the pen refill hopper discharge ports of the two pen refill hoppers, pen refill trays are rotatably arranged. A blanking core hopper is arranged between the two pen refill trays. The blanking core hopper is vertically slidably arranged with respect to the horizontal plane. The middle box transportation chain is chain-driven at the bottom of the blanking core hopper. The middle box detection sensor is arranged on one side of the middle box transportation chain and below the blanking core hopper. Laser detection sensors are arranged on one side of each of the two pen refill trays. The pen refill trays, the blanking core hopper, the middle box transportation chain, the middle box detection sensor and the laser detection sensor are all connected to the control system module.

[0005] Furthermore, the control system module is provided with a PLC control system and an HMI control system, and the control system module conducts data transmission with the ERP production management system.

[0006] Furthermore, a pen refill tray servo motor is arranged on one side of the pen refill tray, and the pen refill tray is rotationally connected to the pen refill tray servo motor.

[0007] Furthermore, a blanking core hopper stepping motor is arranged at the top of the blanking core hopper. An eccentric wheel of the blanking core hopper is rotatably arranged on one side of the blanking core hopper stepping motor, and the blanking core hopper is rotationally matched with one end of the eccentric wheel of the blanking core hopper.

[0008] Furthermore, a vertical linear guide rail is arranged outside the blanking core hopper, and the blanking core hopper is slidably matched with the vertical linear guide rail.

[0009] Furthermore, a stepping motor of the middle box transportation chain is provided at the bottom of the middle box transportation chain, and the stepping motor of the middle box transportation chain is in chain drive cooperation with the middle box transportation chain.

[0010] Furthermore, a vibration motor is provided at the lower end of the blanking core hopper, and the vibration motor is arranged at the bottom of the upper chain of the middle box transportation chain.

[0011] Furthermore, a plurality of grooves are evenly arranged on the outer circumference of the pen core tray.

[0012] The present invention also provides a method for an automatic counting device for pen core packaging, which includes the following steps:

[0013] Step 1: Load the pencil cores from the pen core hopper feed port into two pen core hoppers. After filling the two pen core hoppers, neatly place the middle boxes on the middle box transportation chain;

[0014] Step 2: The stepping motor of the middle box transportation chain drives the middle box transportation chain to rotate. When the middle box rotates to the middle box detection sensor, after the middle box detection sensor recognizes and detects the middle box, the stepping motor of the middle box transportation chain stops running;

[0015] Step 3: After the stepping motor of the middle box transportation chain stops running, the stepping motor of the blanking core hopper drives the eccentric wheel of the blanking core hopper to rotate. The eccentric wheel of the blanking core hopper drives the blanking core hopper to descend into the middle box and flatten the bottom of the middle box. At this time, the pencil cores flow from the discharge ports of the two pen core hoppers into the corresponding grooves of the two pen core trays respectively. Only one pencil core can be placed in one groove. The two pen core tray servo motors drive the corresponding pen core trays to rotate. The laser detection sensor on one side of the pen core tray emits laser. Each time the laser is blocked by the pencil core in the pen core tray, it is counted once. When the pencil core in the pen core tray rotates to the blanking core hopper, the pencil core is affected by gravity and thus falls into the middle box along the blanking core hopper. When the number of pencil cores reaches the preset value, the pen core tray servo motor and the pen core tray stop working, and the vibration motor starts to compact the pencil cores in the middle box;

[0016] Step 4: After the pencil cores are compacted, the stepping motor of the blanking core hopper drives the eccentric wheel of the blanking core hopper to rotate. The eccentric wheel of the blanking core hopper drives the blanking core hopper to rise back to the initial position. The stepping motor of the middle box transportation chain drives the middle box transportation chain to rotate to transport the filled middle box out, completing one cycle, and the device starts to run automatically.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. The present invention adopts an automated packaging method to replace the traditional manual packaging method, effectively reducing the workload of the staff, thereby reducing the rest times of the staff during the operation process, increasing the daily output from 55 boxes to 70 boxes, and effectively improving the work efficiency of pen core packaging;

[0019] 2. The present invention replaces the traditional manual weighing method with a counting method using a counting machine, making the number of pen refills in each box completely accurate and avoiding the error in the number of pen refills in each box caused by the inconsistent weight of single pen refills.

[0020] 3. The present invention changes the traditional manual operation mode in an information-based mode, greatly improving the production management efficiency of pen refill packaging. The application of the control system module and the data of the ERP production management system improves the automation and intelligence level in the pen refill production process, resulting in a significant increase in production efficiency.

A PLC control system and an HMI control system are arranged in the control system module 12. The control system module 12 transmits data to the ERP production management system.

[0031] During the operation of the device, the control system module 12 is the core part of the pen refill packaging automatic counting machine. The control system of the control system module 12 mainly consists of a Siemens PLC control system and an HMI control system. Among them, the control system module 12 can configure the working parameters of the automatic line using a configuration program, detect the status data of the automatic line equipment using detection equipment, realize the automatic counting and automatic boxing of the equipment, process raw materials using the transportation automatic line to realize the automatic transportation of the equipment, and display the configured working parameters and detect the status data of the equipment using the display of the control system module 12, saving time and labor costs and improving work efficiency.

[0036] Step 3: After the middle box transportation chain stepping motor 7 stops running, the blanking hopper stepping motor 5 drives the blanking hopper eccentric wheel 9 to rotate. The blanking hopper eccentric wheel 9 drives the blanking hopper 3 to descend into the middle box and flatten the bottom of the middle box. At this time, the pencil leads flow from the discharge ports of the two pencil lead hoppers 1 into the grooves of the corresponding two pencil lead trays 2 respectively. Only one pencil lead can be placed in one groove. The two pencil lead tray servo motors 4 drive the corresponding pencil lead trays 2 to rotate.

[0037] Step 4: After the pencil leads are compacted, the blanking hopper stepping motor 5 drives the blanking hopper eccentric wheel 9 to rotate. The blanking hopper eccentric wheel 9 drives the blanking hopper 3 to rise back to the initial position.
