Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery, and particularly to a multi-channel automatic cartoning device. Background Art

[0002] In the field of existing packaging equipment, automatic cartoning devices are widely used in industries such as food, medicine, and electronic products to automatically pack materials (such as bottles, cans, bagged products, small parts, etc.) into cartons; traditional cartoning devices usually include a material transmission mechanism and a blanking mechanism. The material is transported to the blanking area through a conveyor belt or other transmission devices, and then the blanking mechanism opens, allowing the material to fall into the carton below under the action of gravity or auxiliary pushing; during the transportation process, the material may shift due to factors such as fluctuations in transmission speed, mechanical vibration, or friction, resulting in uneven spacing when entering the blanking area, affecting subsequent accurate blanking, and even causing material accumulation or missed loading. Summary of the Invention

[0003] The purpose of the present invention is to provide a multi-channel automatic cartoning device to solve the problems existing in the transportation process of materials as mentioned in the above background art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A multi-channel automatic cartoning device, comprising: a frame and a feeding mechanism, a blanking station, and a carton transmission mechanism provided on the frame; The feeding mechanism includes a transmission mechanism and a material limiting component provided on the transmission mechanism. The material limiting component is used to sequentially transport the materials on the transmission mechanism to the blanking station; The blanking station includes two movable pallets, a first detector, and a driving member. The driving member is used to drive the two movable pallets to move away from each other after the first detector detects that materials enter the blanking station, so as to open the blanking station and allow the materials to fall into the cartons on the carton transmission mechanism.

[0005] Preferably, the material limiting component includes a first cylinder, a third cylinder, and third detectors respectively provided on the first cylinder and the third cylinder. The first cylinder and the third cylinder are sequentially provided on the transmission mechanism along the transmission direction of the transmission mechanism. Both the first cylinder and the third cylinder are used to extend when the third detector detects materials, so as to prevent the materials from passing through the first cylinder and the third cylinder. The first cylinder and the third cylinder are also used to shorten when the third detector does not detect materials.

[0006] Preferably, the transmission mechanism includes a belt transmission device, two side baffles respectively provided on both sides of the belt transmission device, and an adjusting member for changing the distance between the two side baffles.

[0007] Preferably, a second detector is provided on the belt conveyor, the second detector is located upstream of the first cylinder, a second cylinder is provided on the side wall of the belt conveyor, and openings for the movable end of the second cylinder to pass through are provided on the side walls of the two side baffles.

[0008] Preferably, a guide plate is provided on the side wall of the belt conveyor to guide the materials pushed down by the second cylinder.

[0009] Preferably, there are several feeding stations and feeding mechanisms, and they correspond to each other one by one. The feeding stations are arranged on the rack in sequence along the transmission direction of the packaging box transmission mechanism.

[0010] Preferably, the driving member includes a conveyor belt mechanism and a driving device for driving the conveyor belt mechanism to drive. Two connecting members are provided on the conveyor belt of the conveyor belt mechanism, and the two connecting members are respectively connected to the two movable pallets.

[0011] Preferably, the packaging box transmission mechanism includes a transmission device and several limiting blocks. The several limiting blocks are arranged on the transmission device at intervals in sequence along the transmission direction of the transmission device.

[0012] Compared with the prior art, the beneficial effects of the present invention are: 1. The positions of the materials are monitored in real time by the third detectors on the first cylinder and the third cylinder. When it is detected that the materials reach the set position, the cylinders immediately extend and intercept the subsequent materials to prevent them from continuing to be transmitted downstream; when the detection signal disappears, the cylinders contract to release the restriction, enabling the materials to pass through orderly, effectively avoiding the accumulation of materials at the blanking station, and ensuring the continuity and accuracy of the box loading process; 2. When there are signals from the second detector, the third detector of the first cylinder, and the third detector of the third cylinder, the second cylinder extends to push the materials off the belt conveyor, removing the materials on the belt conveyor, so that the materials can continue to be fed onto the belt conveyor without being blocked.

[0016] Embodiment 1 Please refer to Figure 1 , a multi-channel automatic box loading device, comprising: a frame 1 and a controller (PLC controller), and a feeding station 2, a loading mechanism 3 and a packaging box transmission mechanism 4 are installed on the frame 1; the feeding station 2 is located above the packaging box transmission mechanism 4, and the loading mechanism 3 is located on one side of the feeding station 2

[0017] Please refer to Figure 1 , Figure 2 and Figure 3 , the feeding station 2 includes two movable pallets 201, a first detector 202 and a driving member 5; the two movable pallets 201 are rotatably arranged on the frame 1, the two movable pallets 201 are symmetrically arranged, and the vertical section of the movable pallet 201 is L-shaped. The first detector 202 is installed on the frame 1 and is located above the two movable pallets 201; the driving member 5 includes a transmission belt mechanism 502 and a driving device 501. The transmission belt mechanism 502 includes two rotating shafts and a transmission belt sleeved on the outer walls of the two rotating shafts. The two rotating shafts are rotatably installed on the frame 1. The driving device 501 includes a motor and a reducer connected to the output shaft of the motor. The output shaft of the reducer is connected to one rotating shaft. Two connectors 203 are arranged on both the upper and lower sides of the transmission belt (when the transmission belt drives, the moving directions of the two connectors 203 are opposite), and the two connectors 203 are respectively connected to the two movable pallets 201

[0018] Please refer to Figure 1 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in Figure 1 , Figure 4 , Figure 5 , Figure 6 and Figure 7 , the loading mechanism 3 includes a transmission mechanism 301 and a material limiting component arranged on the transmission mechanism 301. The material limiting component includes a first cylinder 302, a third cylinder 306, and third detectors 307 respectively arranged on the first cylinder 302 and the third cylinder 306. The first cylinder 302 and the third cylinder 306 are sequentially arranged on the transmission mechanism 301 along the transmission direction of the transmission mechanism 301.

[0019] It should be noted that the third detector 307 is the same as the first detector 202, and both are photoelectric sensors.

[0020] Please refer to Figure 1 As shown in Figure 1 , the packaging box transmission mechanism 4 includes a transmission device 401 and a plurality of limiting blocks 402. The plurality of limiting blocks 402 are sequentially arranged at intervals on the outer side wall of the conveyor belt of the transmission device 401 along the transmission direction of the transmission device 401. A placement groove is formed between two adjacent limiting blocks 402, and the interior of the placement groove is used for placing the packaging box.

[0021] Working principle: The packaging boxes are successively placed into the placement slots of the packaging box transmission mechanism 4 (the placement of the packaging boxes is operated by an external manipulator, and the upper part of the packaging box is open), and the materials are successively placed on the feeding mechanism 3 and transmitted by the transmission mechanism 301; when a material passes through the first cylinder 302 and moves below the third detector 307 on the first cylinder 302, after the third detector 307 detects the material (this material is located downstream of the first cylinder 302), the controller controls the first cylinder 302 to extend to prevent subsequent materials from continuing to cross the first cylinder 302. After the material continues to be transmitted and moves away from below the third detector 307 on the first cylinder 302, and the third detector 307 no longer detects the material, the controller controls the first cylinder 302 to contract to allow subsequent materials to continue to be transmitted to the area of the first cylinder 302, and this operation is repeated; when the material that has crossed the third detector 307 on the first cylinder 302 is detected when it moves below the third detector 307 of the third cylinder 306, the controller controls the third cylinder 306 to extend to prevent subsequent materials from continuing to cross the third cylinder 306. After the material continues to be transmitted and moves away from below the third detector 307 on the third cylinder 306, and the third detector 307 no longer detects the material, the controller controls the third cylinder 306 to contract to allow subsequent materials to continue to be transmitted to the area of the third cylinder 306, and this operation is repeated; the materials that have crossed the third detector 307 on the third cylinder 306 are transmitted to the two movable pallets 201 at the discharging station 2. After the first detector 202 detects that the materials are in place, the controller controls the driving device 501 of the driving member 5 to operate, causing the conveyor belt mechanism 502 to drive, and driving the two connecting members 203 to drive the two movable pallets 201 away, so that the materials on the discharging station 2 fall into the packaging boxes below; after the discharging is completed, the controller controls the driving device 501 to cause the two connecting members 203 to drive the two movable pallets 201 to reset, and also controls the packaging box transmission mechanism 4 to convey a certain distance to move the controlled packaging box to directly below the discharging station 2.

[0022] It should be noted that the two third detectors 307 are respectively installed on the side walls of the first cylinder 302 and the third cylinder 306 close to the discharging station 2.

[0023] In this embodiment, as a further optimized solution, please refer to Figure 4 and Figure 5 , the transmission mechanism 301 includes a belt transmission device 3011, two side baffles 3012 and two adjusting members 3013; the two adjusting members 3013 are respectively installed on both sides of the frame of the belt transmission device 3011. The adjusting member 3013 includes a support frame, a moving rod slidably installed on the support frame, and a bolt for fixing the moving rod. The side baffle 3012 is installed on the moving rod. By pushing the moving rod to move, the distance between the two side baffles 3012 is changed to adapt to the transmission of materials of different sizes on the belt transmission device 3011.

[0024] In this embodiment, as a further optimized solution, please refer to Figure 4 , Figure 5 and Figure 7 . A second detector 304 (photoelectric sensor) is provided on the belt conveyor 3011. The second detector 304 is located upstream of the first cylinder 302. A second cylinder 305 is provided on the side wall of the belt conveyor 3011. The second cylinder 305 is located between the second detector 304 and the first cylinder 302. Openings 3014 are provided on the side walls of the two side baffles 3012. The openings 3014 are for the moving end of the second cylinder 305 to pass through; the second detector 304 is used to detect whether there is material at the inlet of the belt conveyor 3011; when signals are received from the second detector 304, the third detector 307 of the first cylinder 302, and the third detector 307 of the third cylinder 306 (indicating that materials have accumulated on the belt conveyor 3011 and the materials have accumulated to the inlet of the belt conveyor 3011), at this time, the controller controls the second cylinder 305 to extend, so that the moving end of the second cylinder 305 moves through the opening 3014 of one side baffle 3012, contacts the materials on the belt conveyor 3011, and pushes the materials through the opening 3014 of the other side baffle 3012, pushing the materials off the belt conveyor 3011, reducing the accumulated length of the materials on the belt conveyor 3011, removing the materials on the belt conveyor 3011, and enabling the materials to continue to be fed onto the belt conveyor 3011 without being blocked.
