TECHNICAL FIELD

[0001] The utility model relates to automatic packaging equipment technical field especially, relates to a kind of drop bag packing machine. BACKGROUND

[0002] Drop bag packing machine is a kind of mechanical equipment specially used to automatically pack various types of bags (such as food bags, medical bags or other industrial goods bags, etc.). This machine is usually suitable for the production line of bagged products, and can realize the automation operation from the arrangement, conveying and positioning of the bags to the final packing. Common on the market are mostly small bag drop packing, and the equipment can only be used for packing bags of a single size during operation. However, in actual production, there are often cases where the packaging boxes are the same, but the sizes of the bagged products inside are different, such as 5KG bagged products and 10KG bagged products. The length of the 5KG bagged products is the same as the width of the 10KG bagged products, and they share the same size packaging box. The 5KG bagged products are dropped into the packaging box in the first direction during packing, while the 10KG bagged products need to be dropped into the packaging box in the second direction perpendicular to the first direction. For the packaging and production of such products in the past, the equipment needs to be adjusted after completing the packing and production of the 10KG bagged products, and then the equipment structure needs to be adjusted to adapt to the packing production of the 5KG bagged products. The operation is complicated. Therefore, it is necessary to optimize the structure of the existing drop bag packing machine. SUMMARY

[0004] The technical solution to achieve the purpose of the utility model is as follows:

[0005] A drop bag packing machine includes a machine frame, a bag feeding part and a box feeding part that extend into the machine frame and are arranged in an upper and lower distribution. The upper part of the bag feeding part is provided with a bag turning mechanism and a bag pushing mechanism in sequence along the conveying direction, and the end is provided with a bag turning mechanism. The bag turning mechanism is provided with a lifting mechanism below the bag turning mechanism, and the conveying plane of the lifting mechanism overlaps the conveying plane of the box feeding part. The bag turning mechanism includes a clamping part that rotates around its own vertical axis. The clamping part includes a pair of clamping plates that can rotate and open and close. The clamping plates are used to clamp the bag on the bag feeding part and turn to the designated position. The bag turning mechanism is used to receive the bag pushed by the bag pushing mechanism, and is suitable for dropping the bag into the box lifted by the lifting mechanism.

[0006] Furthermore, a top plate is fixedly mounted on the top of the frame, and a planetary reducer is fixedly mounted on the top plate. The clamping part is rotatably suspended on the lower surface of the top plate by the planetary reducer, and a servo motor is coaxially fixedly connected to the input end of the planetary reducer.

[0007] Furthermore, the clamping part includes a mounting base fixedly connected to the output end of the planetary reducer. A connecting shaft rotatably mounted on the mounting base is provided parallel between the two sides of the mounting base. A connecting plate and a connecting block are fixedly connected to the connecting shaft. The clamping plate is detachably mounted on the lower end of the corresponding connecting plate. A clamping cylinder is connected between the connecting block and the top surface of the mounting base. The cylinder body and piston rod of the clamping cylinder are respectively hinged to the mounting base and the connecting block.

[0008] Furthermore, the bag pushing mechanism includes a translation mechanism fixedly mounted on the top of the machine frame and extending above the bag turning mechanism. A support frame is fixedly suspended on the moving end of the translation mechanism, and a lifting mechanism is fixedly mounted on the support frame. The output end of the lifting mechanism is provided with a bag pushing plate.

[0009] Furthermore, the translation mechanism includes a servo belt conveyor fixed on the frame and a pair of guide rail assemblies arranged parallel to the servo belt conveyor. The support frame is fixed on the moving blocks of the two guide rail assemblies and is fixedly connected to the belt of the servo belt conveyor.

[0010] Furthermore, the lifting mechanism includes a lifting cylinder fixed on a support frame and a guide rod assembly arranged parallel to the lifting cylinder. The piston rod of the lifting cylinder is arranged vertically downward and connected to the push bag plate by a floating joint. The lower end of the guide rod assembly is connected to the push bag plate.

[0011] Furthermore, a cushioning pad is provided on the side of the bag pusher plate near the bag turning mechanism.

[0012] Furthermore, the box feeding section is a roller conveyor, and the box lifting mechanism includes a chain lift fixedly installed at the bottom of the frame section. The moving end of the chain lift is fixedly connected to a lifting platform, and the lifting platform includes multiple lifting rods arranged in parallel and offset from the conveying rollers of the roller conveyor.

[0013] Furthermore, it also includes a box body limiting part, which includes a limiting rod arranged parallel above the lifting platform and connected to the moving end of the chain lifting machine.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] (1) This utility model uses a bag feeding section and a box feeding section distributed vertically to transport bags to be packaged and empty boxes respectively. When the bag passes through the bag turning mechanism, according to the setting, the bag can be clamped by the clamping section and the direction can be changed by rotation. Then, it passes through the bag pushing mechanism and is pushed by translation to move the bag to the bag turning mechanism, and finally falls into the empty box below.

[0018] (3) The clamping part of this utility model drives the connecting shaft to rotate through two clamping cylinders via a connecting block, thereby driving the two clamping plates to rotate and clamp, thus achieving both clamping the bag below and not interfering with the conveying of the bag; in addition, the clamping plates are detachable and easy to replace, which improves versatility and saves costs.

[0019] (4) The bag pushing mechanism of this utility model is driven by a translation mechanism and a lifting mechanism to move and lift the bag pushing plate along the bag conveying direction, thereby realizing that the pushing can move the bag forward without interfering with the bag conveying, and the structure is simple.

[0020] (5) This utility model uses a servo belt conveyor to control the translation of the pusher plate, which is precise in position and efficient in production.

[0021] (6) This utility model uses a lifting cylinder to drive the pusher plate to lift and lower, which has a fast response. At the same time, a guide rod assembly is provided to improve the stability of the lifting and lowering movement.

[0022] (7) This utility model increases the contact friction between the bag and the bag body by setting a buffer pad on the bag pusher plate, while protecting the bag body and reducing the risk of breakage.

[0023] (8) By setting a box limiting part, this utility model can prevent the box from moving forward when it is conveyed to the box lifting mechanism, thereby improving the position accuracy of the box and thus improving the reliability of drop packing.

[0024] (9) This utility model uses a two-section belt conveyor as the bag feeding section, which can realize differential speed conveying, fully taking into account the different time required for bag turning and bag flipping processes, making it easier to automate production control and improve the overall packing efficiency.

Detailed Implementation

[0033] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0034] (Example 1)

[0035] like Figures 1 to 5The drop-type bag packing machine shown includes a frame section 1, a bag feeding section 2, a box feeding section 3, a bag turning mechanism 4, a bag pushing mechanism 5, a bag flipping mechanism 6, and a box lifting mechanism 7. The bag feeding section 2 and the box feeding section 3 both extend into the frame section 1 and are arranged vertically, respectively for conveying bagged products and empty boxes. The bag turning mechanism 4 and the bag pushing mechanism 5 are sequentially suspended above the bag feeding section 2 along the conveying direction. The bag flipping mechanism 6 is located at the end of the conveying section 2. When packaging 10KG bagged products, the bag turning mechanism 4 is not needed. When packaging 5KG bagged products with the same width as the 10KG bagged products, the bag turning mechanism 4 rotates the lower bagged product by 90°, making it directly usable with the entire machine. The bag pushing mechanism 5 then pushes the bagged product horizontally to the bag flipping mechanism 6. The lifting mechanism 7 is located directly below the bag-flipping mechanism 6. Its initial working plane overlaps with the conveying plane of the box feeding section 3. When the empty box is conveyed to the lifting mechanism 7 by the box feeding section 3, it is lifted upward by the lifting mechanism 7 and brought closer to the bag-flipping mechanism 6 above. Finally, the bag product falls into the empty box below through the bag-flipping mechanism 6.

[0036] Specifically, the bag feeding section 2 is a two-section belt conveyor, including a first bag feeder 2-1 and a second bag feeder 2-2 connected sequentially along the conveying direction. The bag turning mechanism 4 is located above the first bag feeder 2-1, and the bag pushing mechanism 5 spans across the second bag feeder 2-2 and the bag flipping mechanism 6. Using a two-section belt conveyor as the bag feeding section enables differential speed conveying, fully considering the different times required for the bag turning and flipping processes, facilitating automated production control, and improving overall packing efficiency.

[0037] A top plate 8 is fixedly mounted on the top of the frame 1, and a planetary reducer 9 is fixedly mounted on the top plate. A servo motor 10 is coaxially fixed to the input end of the planetary reducer 9. The bag-turning mechanism 4 includes a clamping part consisting of a mounting base 4-1, a connecting shaft 4-2, a connecting plate 4-3, a connecting block 4-4, a clamping plate 4-5, and a clamping cylinder 4-6. The mounting base 4-1 is fixedly connected to the output end of the planetary reducer 9, thereby achieving rotational motion around itself with the vertical direction as the rotation axis under the drive of the servo motor 10. Two parallel connecting shafts 4-2 are rotatably mounted on mounting base 4-1 via bearings. Four connecting plates 4-3 are provided, each mounted on one of the two connecting shafts 4-2. Two connecting blocks 4-4, two clamping plates 4-5, and two clamping cylinders 4-6 are also provided. The lower end of the connecting plate 4-3 on the same connecting shaft 4-2 is detachably connected to the same clamping plate 4-5 via screws or similar means. One end of each of the two connecting blocks 4-4 is fixedly connected to one of the two connecting shafts 4-2, and the other end is hinged to the piston rod ends of the two clamping cylinders 4-6 hinged to mounting base 4-1. The clamping cylinders 4-6 drive the connecting shafts 4-2 to rotate, thereby causing the two clamping plates 4-5 to perform a rotational clamping motion.

[0038] The bag-pushing mechanism 5 includes a translation mechanism, a lifting mechanism, a support frame 5-1, and a bag-pushing plate 5-2. The translation mechanism includes a servo belt conveyor 5-3 fixed on the frame 1 and a pair of guide rail assemblies 5-4 parallel to the servo belt conveyor 5-3. Both the servo belt conveyor 5-3 and the guide rail assemblies 5-4 span the second bag feeder 2-2 and the bag-turning mechanism 6. The support frame 5-1 is fixed on the moving blocks of the two guide rail assemblies 5-4 and is fixedly connected to the belt of the servo belt conveyor 5-3, thereby achieving translation under the drive of the servo belt conveyor 5-3. The lifting mechanism includes a lifting cylinder 5-5 fixed on the support frame 5-1 and a guide rod assembly 5-6 parallel to the lifting cylinder 5-5. The piston rod of the lifting cylinder 5-5 is vertically downward and connected to the bag-pushing plate 5-2 with a floating joint, thereby driving the bag-pushing plate 5-2 to move up and down. The lower end of the guide rod assembly 5-6 is connected to the bag pusher plate 5-2 to ensure the stability of the lifting and lowering movement of the bag pusher plate 5-2. In order to prevent the bag pusher plate 5-2 from scratching the bag product, a buffer pad is also provided on the side of the bag pusher plate 5-2 near the bag turning mechanism 6 in this embodiment.

[0039] The bag-flipping mechanism 6 adopts the existing flip-plate structure, which will not be described in detail here. The same structure is widely used in this field, such as the structure disclosed in the patent document with authorization announcement number CN209667442U.

[0040] The box-feeding section 3 is a roller conveyor. The box-lifting mechanism 7 includes a chain lift 7-1 fixedly installed at the bottom of the frame section 1. The moving end of the chain lift 7-1 is fixedly connected to a lifting platform 7-2. The lifting platform 7-2 includes multiple parallel lifting rods that are offset from the conveying rollers of the roller conveyor. The chain lift 7-1 drives the lifting platform 7-2 to rise or fall. When falling, the lifting rods fall exactly between two adjacent conveying rollers, achieving flush alignment with the conveying plane of the box-feeding section 3.

[0041] The lifting mechanism 7 is also equipped with a box limiting part, which includes a limiting rod 7-3 that is parallel to the lifting platform 7-2 and connected to the moving end of the chain lift 7-1. The limiting rod 7-3 is installed on the moving end of the chain lift 7-1 by locking screws and adjusting rods, so that the spacing is adjustable to meet the limiting requirements of boxes of different sizes. A limiting cylinder 7-4 is fixedly installed at the end of any limiting rod 7-3 along the box conveying direction. The piston rod of the limiting cylinder 7-4 is extended and retracted toward the other limiting rod 7-3 and the end is fixedly connected to a baffle plate 7-5, so as to prevent the box from moving forward when it is conveyed to the lifting mechanism 7, thereby improving the positional accuracy of the box and thus improving the reliability of drop packing.

[0042] This invention uses a bag-feeding section 2 and a box-feeding section 3, which are distributed vertically, to transport bags to be packaged and empty boxes respectively. When the bag passes through the bag-turning mechanism 4, it can be clamped by the clamping part according to the setting, and its direction can be changed by rotation. Then, it passes through the bag-pushing mechanism 5, and is pushed by translation to move the bag to the bag-flipping mechanism 6, and finally falls into the empty box below. The bag-turning mechanism allows small bags with the same length and width as large bags to be used with this device, so as to take into account at least two different types of bags for drop-packing, thereby helping to achieve efficient and safe production.

[0043] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
