Description

Technical Field

[0001] This utility model belongs to the field of automated packaging technology, and in particular relates to an automatic box-packing fixture for flexible packaging products. Background Technology

[0002] In the production of flexible packaging products (such as boxed items), taking hamburger boxes as an example, after production, multiple hamburger boxes are usually stacked together and sealed in packaging bags to form a single product. This product then needs to be further packed into cartons for bulk transportation. Currently, most automatic carton packing mechanisms on the market use suction cup structures, which use negative pressure to adsorb the product and transfer it into the carton. However, such mechanisms have significant limitations: suction cups can only achieve planar adsorption and cannot adjust the overall size of the product to fit the inner cavity of the carton by squeezing, which easily leads to the need for manual squeezing during packing due to size mismatch; in addition, after the suction cup releases the product, it is easy for the product to pop out of the carton, which not only reduces packing efficiency but may also cause product damage or loose packaging. Utility Model Content

[0003] Based on this, and to address the aforementioned technical problems, an automatic box-packing fixture for flexible packaging products is provided.

[0004] The technical solution adopted in this utility model is as follows:

[0005] An automatic packing fixture for flexible packaging products is characterized by comprising a horizontal fixed plate for fixing to a robotic arm, a stationary clamping plate and a movable clamping plate for compressing and clamping the product back and forth below the fixed plate, a first driving mechanism for driving the movable clamping plate to move closer to or away from the stationary clamping plate, a pressing head for pressing down the product between the stationary clamping plate and the movable clamping plate, and a second driving mechanism for driving the pressing head to move up and down. The stationary clamping plate and the movable clamping plate are arranged opposite to each other. The stationary clamping plate is fixed to the rear of the fixed plate, and the movable clamping plate is located in front of the fixed plate. The first driving mechanism is fixed to the fixed plate and connected to the movable clamping plate. The pressing head is connected to the second driving mechanism, and the second driving mechanism is fixed to the fixed plate.

[0006] The beneficial effects of this utility model are as follows:

[0007] 1. No manual squeezing required, improving automation: Through the front-to-back arrangement of the static and dynamic clamping plates and the drive of the first drive mechanism, the stacked soft packaging products can be mechanically compressed directly, replacing the traditional manual squeezing operation, reducing human intervention and improving the automation level of the packing process.

[0008] 2. Prevent product rebound and improve packing stability: After the product is clamped by the clamping plate and placed into the carton, the second drive mechanism drives the pressing head to further press down on the product, preventing the product from popping out of the carton and ensuring the stability of the product inside the carton.

[0009] 3. Adaptable to different product sizes and enhanced versatility: By adjusting the driving stroke of the first drive mechanism on the moving clamping plate, the clamping distance between the clamping plates can be flexibly changed to adapt to flexible packaging products with different stacking thicknesses, thereby improving the adaptability of the fixture to diverse production needs.

[0010] 4. Compact structure and integrated operation: The clamping and pressing functions are integrated into the same fixture. It is connected to the robot arm through the fixed plate, which can realize continuous actions of product gripping, compression, transfer and pressing, simplifying the equipment structure and improving the continuity and efficiency of packing operations.

[0015] The embodiments of this utility model will be described below with reference to the accompanying drawings. It should be noted that the embodiments described in this specification are not exhaustive and do not represent the only embodiments of this utility model. The corresponding embodiments below are only for clearly illustrating the utility model content of this patent and are not intended to limit its implementation. For those skilled in the art, different variations and modifications can be made based on the described embodiments. Any obvious variations or modifications that fall within the technical concept and utility model content of this utility model are also within the protection scope of this utility model.

[0016] like Figure 1 and Figure 2 As shown, this utility model embodiment provides an automatic packing fixture for flexible packaging products, including a horizontal fixed plate 1100, a static clamping plate 1200, two moving clamping plates 1300, two first driving mechanisms 1400, a pressing head 1500, a second driving mechanism 1600, a first sensing element 1700, and two second sensing elements 1800.

[0017] The horizontal fixing plate 1100 has a fixing structure for fixing to the robot arm. In this embodiment, the fixing structure is a plurality of bolt holes 1110.

[0018] like Figure 3 As shown, the fixing plate 1100 also has two detection holes 1120 and one through hole.

[0019] The stationary clamping plate 1200 and the movable clamping plate 1300 are arranged opposite each other to compress and clamp the product from the front and back below the fixed plate 1100.

[0020] like Figure 2 As shown, the upper edge of the static clamping plate 1200 is integrally connected with a first fixing strip 1210 in the left-right direction. The first fixing strip 1210 is fixed to the rear edge of the lower surface of the fixing plate 1100 by bolts.

[0021] like Figure 1 As shown, the two movable clamping plates 1300 are located in front of the fixed plate 1100 and are arranged side by side, as follows. Figure 2 As shown, each movable clamping plate 1300 has a second fixing strip 1310 integrally connected to its upper edge in the left and right direction. Two first driving mechanisms 1400 are arranged side by side and correspond one-to-one with the two movable clamping plates 1300. The front end of the output shaft of the first driving mechanism 1400 has a transmission plate 1410. The transmission plate 1410 is connected to the second fixing strip 1310 of the corresponding movable clamping plate 1300 by bolts, thereby driving the movable clamping plate 1300 to move closer to or away from the stationary clamping plate 1200.

[0022] The side of the moving clamping plate 1300 facing the stationary clamping plate 1200 has anti-slip texture. For example... Figure 1-3 As shown, each first drive mechanism 1400 is clamped to the upper surface of the fixed plate 1100 by an n-shaped clamp 1420. The two ends of the clamp 1420 are connected to the fixed plate 1100 by bolts, so as to achieve a detachable connection with the fixed plate 1100. Loosening the clamp 1420 can adjust the front and rear position of the first drive mechanism 1400 to adapt to different products.

[0023] In this embodiment, the first drive mechanism 1400 is a cylinder.

[0024] The pressing head 1500 is used to press down the product between the stationary clamping plate 1200 and the moving clamping plate 1300. It is located below the aforementioned through hole. The second drive mechanism 1600 is an electric cylinder, which is fixed on the upper surface of the fixed plate 1100. Its output axis passes downward through the through hole and is connected to the pressing head 1500, thereby driving the pressing head 1500 to rise and fall.

[0025] In practical applications, products may be deformed or have posture deviations (such as inversion or tilting), causing the clamps to fail to clamp the product on the target side, resulting in damage to the carton during packing. Therefore, the first sensor 1700 is located above the rear side of the first drive mechanism 1400 with its sensing end facing downwards, to sense the stroke of the rear end of the output shaft of the first drive mechanism 1400, thereby determining whether the stationary clamping plate and the moving clamping plate are clamping the product on the target side. The first sensor 1700 is fixed to the upper surface of the fixing plate 1100 via the first bracket 1710.

[0026] In this embodiment, when the stationary and moving clamps clamp the product on the target side (such as the two opposite sides of the product), the stroke of the rear end of the output shaft of the first drive motor 1400 will be larger. This rear end of the output shaft will then be sensed by the first sensor 1700, indicating that the stationary and moving clamps are clamping correctly. Conversely, if the stationary and moving clamps clamp the product on the other two opposite sides, the stroke of the rear end of the output shaft of the first drive motor 1400 will be smaller, and thus will not be sensed by the first sensor 1700, indicating that the stationary and moving clamps are not clamping correctly. Taking a hamburger box as an example, multiple hamburger boxes are stacked together and sealed in a packaging bag to form a product. The stationary and moving clamps compress and clamp the product on both sides of the stacking direction. In this case, the rear end of the output shaft of the first drive motor 1400 will be sensed by the first sensor 1700.

[0027] Of course, for different products, the output shaft of the first drive motor 1400 being sensed by the first sensor 1700 can indicate that the stationary clamping plate and the moving clamping plate are not being clamped correctly, while the output shaft of the first drive motor 1400 not being sensed by the first sensor 1700 can indicate that the stationary clamping plate and the moving clamping plate are being clamped correctly.

[0028] It is understandable that the first sensor 1700 can also sense other parts of the output shaft of the first drive motor 1400, and these parts can be equipped with markers to facilitate sensing by the first sensor 1700.

[0029] In practical applications, there may be situations where the clamp is missing or the product is lost. Therefore, the second sensing element 1800 is used to sense whether there is a product between the stationary clamp and the moving clamp. The sensing ends of the two second sensing elements 1800 face downwards to the corresponding detection holes 1120, and are respectively fixed to the upper surface of the fixing plate 1100 by a second bracket 1810.

[0030] The first sensing element 1700 is a proximity switch, and the second sensing element 1800 is a photoelectric sensor.

[0031] The working principle of the fixture in this embodiment of the utility model is as follows:

[0032] Material handling: First, open the clamp (moving clamp 1300 is away from stationary clamp 1200). The robot arm carries the clamp and moves it so that the stationary clamp 1200 and the moving clamp 1300 are on two opposite sides of the product. After they are in place, the clamp closes and the moving clamp 1300 compresses the product to a certain extent (e.g., 3-4 cm).

[0033] Unloading: The robot moves the clamp to the bottom of the carton and releases the clamp (only the cylinder is depressurized). Then the second drive mechanism 1600 drives the pressing head 1500 to press down on the product. Finally, the robot carries the clamp away from the carton, retracts the pressing head 1500 and opens the clamp.

[0034] Inspection: After the material is picked up, the first sensor 1700 detects whether the clamp is holding the product correctly. If it is not, an alarm will be triggered to remind the staff to check and prevent the carton from breaking when the product is put into it.

[0035] During operation, the second sensor 1800 remains in a continuous monitoring state. If a missing package (product missing) or a dropped package (product fallen) occurs, an alarm will be triggered to alert staff to check. This prevents products from being missed during packing, resulting in insufficient quantity in the boxes and quality issues.

[0036] As can be seen from the above, the automatic packing fixture for flexible packaging products provided in this embodiment of the present invention has the following beneficial effects:

[0037] 1. No manual squeezing required, improving automation: Through the front-to-back arrangement of the static and dynamic clamping plates and the drive of the first drive mechanism, the stacked soft packaging products can be mechanically compressed directly, replacing the traditional manual squeezing operation, reducing human intervention and improving the automation level of the packing process.

[0038] 2. Prevent product rebound and improve packing stability: After the product is clamped by the clamping plate and placed into the carton, the second drive mechanism drives the pressing head to further press down on the product, preventing the product from popping out of the carton and ensuring the stability of the product inside the carton.

[0039] 3. Adaptable to different product sizes and enhanced versatility: By adjusting the driving stroke of the first drive mechanism on the moving clamping plate, the clamping distance between the clamping plates can be flexibly changed to adapt to flexible packaging products with different stacking thicknesses, thereby improving the adaptability of the fixture to diverse production needs.

[0040] 4. Compact structure and integrated operation: The clamping and pressing functions are integrated into the same fixture. It is connected to the robot arm through the fixed plate, which can realize continuous actions of product gripping, compression, transfer and pressing, simplifying the equipment structure and improving the continuity and efficiency of packing operations.

[0041] In addition, the detection by the first and second sensors can prevent the carton from breaking and prevent missing or swapped packages.

[0042] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
