Description

Technical Field

[0001] This utility model relates to the field of filling production lines, specifically a material receiving device for the discharge port of a liquid packaging machine. Background Technology

[0002] The final stage of our factory's liquid bagged products is filling and sealing. Most of this stage is completed on an assembly line. Currently, we use a relatively mature liquid filling production line, which achieves continuous production by moving the packaging bags horizontally, resulting in automated, continuous, and efficient production. However, after filling and sealing, subsequent operations are done manually, with workers performing sorting and packing. This leads to low production efficiency, high labor costs, and unavoidable operational errors. Utility Model Content

[0003] The purpose of this utility model is to provide a material receiving device for the discharge port of a liquid packaging machine, which automates the unloading and packing of bagged products after filling, thereby improving efficiency and reducing labor.

[0004] To achieve the above objectives, this utility model employs the following technical solution:

[0005] A material receiving device for the discharge port of a liquid packaging machine includes a base. A swing arm with a 90-degree swing stroke is hinged to the middle of the base. The swing arm has an upper stroke in an upright state and a lower stroke in a horizontal state based on the swing stroke. A swing seat is rotatably connected to the side of the base near the lower stroke. A smooth rod is slidably connected to the swing seat. A hinge seat is provided at the end of the smooth rod away from the swing seat and rotatably connected to the swing arm. A horizontally extending mounting rod is fixed on the hinge seat. A suction cup assembly is provided at the end of the mounting rod. When the swing arm is at the upper stroke, the suction position of the suction cup assembly corresponds to the packaging bag at the discharge end of the filling line. When the swing arm is at the lower stroke, a guide cylinder corresponding to the upper and lower parts of the packaging bag is provided below the suction cup assembly. The bottom end of the guide cylinder has a discharge port.

[0006] The base has a bearing seat in the middle, the bottom end of the swing arm is rotatably mounted on the bearing seat, a fixed shaft is provided on one side above the bearing seat, the swing seat is rotatably mounted on the fixed shaft, the top end of the swing arm is fixed with a horizontal shaft, the hinge seat is rotatably connected to the horizontal shaft, and the fixed shaft, bearing seat, horizontal shaft and mounting rod are arranged parallel in length direction.

[0007] The base is rotatably mounted with a drive shaft higher than the bearing seat at the end away from the fixed axis. The drive shaft is driven by a motor. A drive rod is connected to the drive shaft. A connecting rod is rotatably connected to the end of the drive rod away from the drive shaft. The connecting rod is a straight rod. A hinge shaft is provided in the middle of the swing arm. The end of the connecting rod away from the drive rod is rotatably sleeved with the hinge shaft in the middle of the swing arm.

[0008] The end of the mounting rod is fixed with a mounting base. The mounting base is in an upright state when the swing arm is vertical and in a horizontal state when the swing arm is horizontal. There are multiple suction cup assemblies, which are installed and distributed along the length of the mounting base.

[0009] A counter is installed inside the feed cylinder.

[0010] A conveyor belt is provided below the guide cylinder. The conveyor belt is located below the guide cylinder. A position sensor is provided below the corresponding discharge port. The start of the conveyor belt is linked to the counting of the counter, and the stop of the conveyor belt is linked to the position sensor.

[0011] It also includes a fixedly installed stop block, which has an upright mating surface on the side near the swing arm. When the swing arm is at the upper end of its stroke, the mating surface is close to the suction cup assembly.

[0012] The top of the guide cylinder is provided with a receiving port, and the discharge port is slightly smaller than the receiving port.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] Through the above improvements, this device can automate the boxing operation. It uses a swing arm and suction cup assembly to grab, flip, and put down the product packaging bags after filling and sealing, achieving fixed-point placement to meet the boxing requirements. The guide cylinder further guides the position and boxes downwards, completing the fully automated production line operation, improving production efficiency and quality, and greatly reducing labor costs.

[0023] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0024] This device is mainly used in conjunction with an automated production line for liquid packaging machines. In the production process up to the discharge port, a chute and conveyor belt 14 are used. The finished products slide down the slope of the chute and are guided onto the conveyor belt 14, and then transported to the downstream process via the conveyor belt 14. On both sides of the conveyor belt 14, workers can manually sort and pack the finished products. Currently, the products are mainly packaged in boxes of 20. During peak production periods, the work at this station is quite intense, with high production pressure and labor intensity for workers. In addition, manual counting and packing inevitably introduces errors. A separate load-bearing verification step is also required in the later stages, making the post-discharge processes labor-intensive, time-consuming, cumbersome, and prone to errors.

[0025] After improvement, this device is installed at the discharge port of the packaging machine to replace the conveyor belt for receiving materials. The existing packaging machine uses a row of clamping and pushing mechanisms to handle the material through grasping, spreading, filling, and sealing operations, before it reaches the end discharge position horizontally. This device is installed at this position, and its main structure includes a base 1 that is fixedly mounted at the discharge port of the packaging machine.

[0026] The base 1 has a bearing seat in the middle, and a swing arm 2 is rotatably mounted on the bearing seat. A drive shaft 3 and a fixed shaft are respectively provided on both sides of the bearing seat. The fixed shaft is fixedly mounted on the base 1, and the drive shaft 3 is rotatably mounted on the base 1. The fixed shaft and the drive shaft 3 are respectively located above the bearing seat.

[0027] A drive rod 4 is fixed on the drive shaft 3. A connecting rod 5 is rotatably connected to the end of the drive rod 4 away from the drive shaft 3. The connecting rod 5 is a straight rod. A hinge shaft 6 is provided in the middle of the swing arm 2. The end of the connecting rod 5 away from the drive rod 4 is rotatably connected to the hinge shaft 6 in the middle of the swing arm 2, thereby indirectly transmitting the drive rod 4 to control the swing arm 2. A motor is installed at one end of the base 1. The output shaft of the motor is connected to the drive shaft 3 through a reduction gearbox (gear reduction gearbox), realizing the motor's drive rotation of the drive shaft 3. When the drive shaft 3... When driven by the motor, the swing arm 2 can be swung by the drive rod 4, so that the swing arm 2 has a swing stroke of 90 degrees. Based on the swing stroke, the swing arm 2 has an upper end and a lower end. When the swing arm 2 is at its upper end, the swing arm 2 is in an upright state. When the swing arm 2 is at its lower end, the swing arm 2 is in a horizontal state near the fixed axis. The swing range of the swing arm 2 is (on the side near the fixed axis) to perform a right-angle swing reciprocating motion from vertical to horizontal.

[0028] The top of the swing arm 2 is provided with a horizontal shaft 7 perpendicular to the swing arm 2. A hinge seat 8 is rotatably sleeved on the horizontal shaft 7. A smooth rod 9 and a mounting rod 10 integrally formed therewith are fixedly connected to the hinge seat 8. The smooth rod 9 and the mounting rod 10 are arranged perpendicular to each other. The length direction of the mounting rod 10 is parallel to the axial direction of the bearing seat. The mounting rod 10 extends horizontally towards the feed port. A mounting seat 16 is provided at the end of the mounting rod 10 away from the swing arm 2. A suction cup assembly 17 is fixed on the mounting seat 16. Two suction cup assemblies 17 are provided to grip the top and bottom of the packaging bag respectively during gripping, so as to obtain a more stable gripping effect. When the swing arm 2 is at the upper end of its stroke, the suction cup assemblies 17 are distributed vertically, and the suction port of the suction cup assembly 17 is vertical and faces the drive shaft 3, which facilitates the suction gripping of the packaging bag at the end of the packaging line. When the swing arm 2 is at the lower end of its stroke, the suction cup assemblies 17 are distributed horizontally. The optical rod 9 is a straight cylindrical mirror-finish rod, facilitating smooth sliding. A swing seat 11 is rotatably connected to the fixed shaft. The swing seat 11 has sliding holes extending through it on both sides. The optical rod 9 passes through these sliding holes and slides within them. (The text abruptly ends here.) Figure 1-3 The positioning and sliding constraint of the swing seat 11 on the left side of the light rod 9, combined with the hinge constraint of the top of the swing arm 2 on the right end of the light rod 9, allows the light rod 9 to achieve a linkage action that flips the hinge seat 8 in coordination with the swing stroke of the swing arm 2 and the positioning and sliding of the light rod 9 itself. This results in the suction cup assembly 17 being distributed vertically when the swing arm 2 is at the upper end of its stroke. As the swing arm 2 swings downward from the vertical to the fixed axis side during the swing stroke, the suction cup assembly 17 gradually flips from vertical to horizontal, so that the packaging bag can be put down by closing the negative pressure, flipping the packaging bag from upright to horizontal and placing it at a fixed point.

[0029] To facilitate the gripping action of the suction cup assembly 17, a stop block 12 is fixed to one side of the frame via a bracket. The stop block 12 has an upright mating surface 13 on the side near the swing arm 2. In application, the mating surface 13 is installed at the discharge position of the packaging line and is located on the back side of the packaging bag. When the swing arm 2 is upright, the suction cup is located on the front side of the packaging bag. By moving towards the packaging bag and using negative pressure adsorption, the suction cup grips the packaging bag. The mating surface 13 supports the packaging bag on the back side to prevent the packaging bag from shifting, making the gripping more effective and preventing missed gripping.

[0030] A conveyor belt 14 is provided on one side of the base 1, and the existing conveyor belt 14 can be reused. A guide cylinder 15 is fixed on the base 1 or the frame of the conveyor belt 14 above the conveyor belt 14. The guide cylinder 15 is a straight cylinder with a size adapted to the packaging bag. The guide cylinder 15 is arranged vertically. The top of the guide cylinder 15 is provided with a receiving port and the bottom of the guide cylinder 15 is provided with a dropping port. When the swing arm 2 is at the lower end of its stroke, the receiving port corresponds to the position of the packaging bag adsorbed on the suction cup assembly 17.

[0031] The guide cylinder 15 is shaped like a bucket, wider at the top and narrower at the bottom. Therefore, the discharge port is slightly smaller than the receiving port. The receiving port, which is slightly larger than the packaging bag, provides better adaptability for the bag's placement. The discharge port, which corresponds to the size of the packaging bag, more precisely controls the bag's position. In actual use, a packaging box is placed below the discharge port, and the device can automatically pack the boxes. A counter is installed inside the guide cylinder 15. The counter uses an infrared or laser sensor to identify passing objects and count them. When the count reaches the predetermined quantity for each box, an alarm is triggered, prompting manual feeding or box replacement.

[0032] Furthermore, the counter can be linked with the conveyor belt 14. When the conveyor belt 14 is directionally conveying from the drive shaft 3 towards the fixed shaft, the position directly below the discharge port of the guide cylinder 15 is the packing position. A position sensor is installed at this position. When the carton reaches the packing position, the conveyor belt 14 stops and packing begins. When the counter calculates that the fallen product bag meets the requirements, the conveyor belt 14 starts conveying the next carton to the packing position, thus achieving continuous packing operations. The loading and alignment of the packaging boxes at the front end of the conveyor belt 14, and the unloading and sealing at the rear end, can be done manually or by other automated devices.

[0033] Through the above improvements, this device can automate the packing operation. The robotic arm grabs the packaging bags, and the continuous swing of the swing arm 2 enables continuous grabbing, flipping, and fixed-point placement, thus efficiently replacing manual labor in the packing operation. The full boxes of products can be manually removed or directly transported to subsequent processes such as quality inspection via the conveyor belt 14, completing the fully automated production line operation, improving production efficiency and quality, and greatly reducing labor costs.
