Description

Technical Field

[0001] The present invention relates to the field of packaging equipment, in particular to a packaging device and a packaging method for a product. Background Art

[0002] At present, the self-service retail industry and the medical and pharmaceutical industry are selling more and more products with higher integration. In order to meet the needs of different customers, it is necessary to classify and package the goods before they are sold or to package them quantitatively. Different packaging generates different labeling and recording requirements to facilitate customers to understand the usage method or couriers to understand relevant information. However, the current integrated sales equipment does not have the packaging function of sheet and plate products (products include but are not limited to all aluminum foil and tin foil products such as tablets, milk tablets, candy tablets, and the packaging of tablets or granules prescribed by doctors is also one of the important needs of the future market), or can only meet the packaging needs of one category, which limits the development of equipment, cannot meet market demand, reduces the experience, and has a bottleneck of incomplete functions. At present, the equipment packaging is mainly for standard items, which can be packaged in batches. The first category is the plastic bag packaging bag of the express bag. The size and size of the bag are certain, which is suitable for flexible packaging of products with a certain volume and a certain weight, but not suitable for light and small packaging such as products. The second category is the packaging of cartons. The packaging box has a unified size, which facilitates the packaging process, causes a waste of packaging space and packaging materials, and the packaging equipment is large in size and cannot adapt to the packaging box of extremely small products. The third type is the high-end robotic gripper method, which adjusts the product direction angle and position, and has an adaptive packaging design that can adapt to different packages and products. For smart self-service equipment, mechanical grippers are very expensive and take up a lot of space, making it difficult to achieve market-oriented operation and promotion. None of the above is suitable for direct packaging of products, which increases the operating time and operating costs of the equipment, and ultimately consumers pay for it, reducing the shopping experience. The fourth type even requires manual assistance in some usage scenarios to complete customized needs. This is one of the important reasons why self-service equipment can only replace part of the manual labor, which hinders the popularization of smart self-service equipment.

[0003] In view of this, it is necessary to provide a product packaging device and packaging method. Summary of the invention

DETAILED DESCRIPTION

[0027] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 As shown, the first embodiment provided by the present application is a product packaging device, whose structure includes a frame 1, and also includes a bag storing mechanism 2, a heat sealing mechanism 3, a bag taking mechanism 4, a conveying mechanism 5 and a flap feeding mechanism arranged on the frame 1, the bag storing mechanism 2 is used to store empty bags 100, the bag taking mechanism 4 is used to grab the empty bags 100 in the bag storing mechanism 2 one by one, the conveying mechanism 5 is used to transport the bag taking mechanism 4 back and forth between the bag storing mechanism 2 and the heat sealing mechanism 3, the flap feeding mechanism is used to feed the product into the hole bag 100 in the bag taking mechanism 4, and the heat sealing mechanism 3 is used to heat-seal the bag 100 in the bag taking mechanism 4 after receiving the product.

[0029] It should be noted that the bag 100 of the present application may be a pearlescent film packaging bag.

[0030] During actual use, the product is placed in the flap mechanism 6, and the empty bag 100 is placed in the bag storage mechanism 2. The conveying mechanism 5 first drives the bag taking mechanism 4 to move to the bag storage mechanism 2 to take out an empty bag 100, and then the conveying mechanism 5 drives the bag storage mechanism 2 to move to the heat sealing mechanism 3. At this time, the opening of the empty bag 100 is located at the top, and then the flap mechanism 6 pours the product into the empty bag 100 and resets it, and then the heat sealing mechanism 3 heat seals the bag opening.

[0031] In the above design, light-weight and small-volume products such as sheets and plates can be directly packaged and sealed, using less space and equipment costs, and can be better integrated and transformed with existing equipment.

[0032] Specifically: Figure 2 As shown, the bag storage mechanism 2 includes a bag storage frame 21, a push plate 22, a guide rod 23, a tension spring 24 and a limiter 25 arranged on the bag storage frame 21. The bag storage frame 21 includes a bag storage groove with an upper opening and a side opening, and the side opening corresponds to the conveying mechanism 5. The push plate 22 is slidably connected to the bag storage frame 21 through the bag storage groove. The number of the guide rod 23 is at least one, and the guide rod 23 is fixedly arranged on the outer wall of the bag storage frame 21 and the extension direction is the same as the sliding direction of the push plate 22. The two ends of the push plate 22 protrude from the bag storage frame respectively. The outer wall of the bag storage frame 21 is horizontally slidably connected to the guide rod 23 through a No. 1 linear bearing, and the two ends of the tension spring 24 are respectively fixedly connected to the No. 1 linear bearing and the outer wall of the bag storage frame 21, so that the push plate 22 slides toward the side opening, and the limiting member 25 includes an upper limiting plate 251 arranged on the bag storage frame 21 for limiting the upper edge of the bag 100 arriving at the side opening, a left limiting plate 252 arranged on the bag storage frame 21 for limiting the left edge of the bag 100 arriving at the side opening, and a right limiting plate 253 for limiting the right edge of the bag 100.

[0033] In actual use, a number of empty bags 100 are stacked in the bag storage slot in a horizontal direction. When there are more than two bags 100 in the bag storage slot, the two outermost bags 100 are respectively against the push plate 22 and the stopper 25. After the bag taking mechanism 4 takes out the bag 100 stopped by the stopper 25, under the elastic tension of the tension spring 24, the push plate 22 is driven to automatically press the remaining bags 100 along the side opening of the slide slot.

[0034] In the above design, the structural design and specific implementation of the bag storage mechanism 2 can effectively store and push the empty bag 100, making it easier for the bag taking mechanism 4 to take the bag.

[0035] Specifically: Figure 3 As shown, the conveying mechanism 5 includes a linear module 51 arranged on the frame 1 along the X direction, and a supporting plate 52 fixedly arranged on the output end of the linear module 51. The bag taking mechanism 4 is fixedly arranged on the supporting plate 52, and the bag storing mechanism 2 and the heat sealing mechanism 3 are arranged on one side of the linear module 51 along the X direction.

[0036] In actual use, the linear module 51 drives the supporting plate 52 to move along the X direction, so that the bag taking mechanism 4 moves back and forth between the bag storing mechanism 2 and the heat sealing mechanism 3 along the supporting plate 52 along the X direction.

[0037] In the above design, the structural design and specific implementation method of the conveying mechanism 5 can effectively realize the back and forth conveyance of the bag taking mechanism 4, ensuring the rapid movement and stable conveyance of the bag taking mechanism 4.

[0038] Specifically: Figure 3 As shown, the bag taking mechanism 4 includes a mounting plate 41 fixedly arranged on the supporting plate 52, a No. 1 cylinder 42 arranged on the mounting plate 41 along the Y direction and with the output end facing the side of the heat sealing mechanism 3, a movable plate 43 fixedly arranged at the output end of the No. 1 cylinder 42, and a plurality of No. 1 suction cups 44 arranged in an array on the movable plate 43, wherein the No. 1 suction cup 44 is horizontally arranged on the movable plate 43 along the Y direction, and the suction port of the No. 1 suction cup 44 faces the side away from the No. 1 cylinder 42.

[0039] In actual use, when the bag taking mechanism 4 is in an empty state, the output end of the No. 1 cylinder 42 shrinks. When the conveying mechanism 5 drives the bag taking mechanism 4 to move to the corresponding position of the side opening of the bag storing mechanism 2, the No. 1 cylinder 42 drives the moving plate 43 to move toward the side opening, so that the No. 1 suction cup 44 sucks the empty bag 100 limited by the limiter 25, and then the output end of the No. 1 cylinder 42 is retracted, and then driven by the conveying mechanism 5 to move to the corresponding position of the heat shrink mechanism.

[0040] In the above-mentioned design, the structural design and specific implementation method of the bag taking mechanism 4 can effectively realize the rapid material taking and stable transportation of the bag taking mechanism 4 .

[0041] Specifically: Figure 1 and Figure 4 As shown, the heat sealing mechanism 3 includes a support frame 31 arranged on the frame 1, an adsorption component 32 arranged on the side of the support frame 31 for cooperating with the bag taking mechanism 4 to adsorb the other side of the bag 100, and a heat sealing component 33 arranged above the support frame 31. The adsorption component 32 includes a fixed plate 321 arranged on one side of the support frame 31 and a plurality of No. 2 suction cups 322 arranged on one side of the fixed plate 321.

[0042] In actual use, after the bag taking mechanism 4 transports the bag 100 to the corresponding position of the No. 2 suction cup 322, the No. 2 suction cup 322 and the No. 1 suction cup 44 respectively adsorb the two sides of the bag 100, so that the bag opening of the bag 100 opens. Then, after the bag 100 receives the product, the bag opening is heat-sealed by the heat sealing component 33.

[0043] In the above design, the structural design and specific implementation of the heat sealing mechanism 3 can realize the effective opening of the bag 100, so that the bag 100 can receive the product easily.

[0044] Specifically: Figure 1 and Figure 4As shown, the heat sealing assembly 33 includes a rotating shaft 331 arranged on the support frame 31 with the Z axis as the rotating axis 331, a motor arranged on the support frame 31 and fixedly connected to the lower end of the rotating shaft 331 for driving the rotating shaft 331 to rotate, a connecting rod 332 fixedly arranged at the upper end of the rotating shaft 331 in a centrally symmetrical manner, a vertical plate 334 arranged on the support frame 31, a number of No. 2 linear bearings 335 and No. 3 linear bearings 336 arranged on the vertical plate 334 along the Y direction, a number of No. 2 guide pillars 337 respectively sleeved in the No. 2 linear bearing 335, and a number of No. 3 linear bearings 336 respectively sleeved in the No. 2 linear bearing 335 and having a length less than that of the No. 2 guide pillars 337. Guide pillar No. 338, connecting plate A339 connecting one end of several guide pillars No. 237, connecting plate a341 connecting the other end of several guide pillars No. 237, connecting plate B340 connecting one end of several guide pillars No. 338, connecting plate b342 connecting the other end of several guide pillars No. 338, a heating pressure block 343 fixedly arranged on one side of the connecting plate B340, pressure block No. 1 344, and an elastic member 333 connecting pressure block No. 1 344 and connecting plate A339, the heating pressure block 343 corresponds to pressure block No. 1 344 in the Y direction, and the two ends of the connecting rod 332 are hinged to the connecting plate a341 and the connecting plate b342 respectively.

[0045] In actual use, after the bag 100 receives the product, the motor rotates, driving the connecting rod 332 to rotate, so that the two ends of the connecting rod 332 respectively drive the connecting plate a341 and the connecting plate b342 to move in opposite directions, so that the connecting plate a341 drives the second guide column 337 and the connecting plate A339 to move synchronously, and the connecting plate b342 drives the third guide column 338, the heating block 343 and the connecting plate B340 to move synchronously. When the No. 1 block 344 applies pressure to the bag 100, it will cause the elastic member 333 to be gradually compressed, and finally the heating block 343 and the No. 1 block 344 squeeze the bag opening from both sides of the bag 100 and heat it to achieve heat sealing.

[0046] In the above design, the mechanism design and specific implementation method of the heat sealing assembly 33 can effectively achieve rapid sealing of the bag 100 .

[0047] Specifically: Figure 4 As shown, the connecting rod 332 includes a rod 3321 fixedly connected to the upper end of the rotating shaft 331, a rod 3322 of which one end is hinged to one end of the rod 3321, and a rod 3323 of which one end is hinged to the other end of the rod 3321, the other end of the rod 3322 is hinged to the connecting plate a341, the other end of the rod 3323 is hinged to the connecting plate b342, the two ends of the rod 3321 are symmetrical along the axis of the rotating shaft 331, and the lengths of the rod 3322 and the rod 3323 are equal.

[0048] During actual use, the first rod 3321 rotates horizontally along with the rotating shaft 331, thereby driving the second rod 3322 and the third rod 3323 to rotate.

[0049] In the above design, the structural design and specific implementation of the connecting rod 332 can effectively realize the central symmetrical rotation.

[0050] Specifically: Figure 5 As shown, the flap mechanism 6 includes a No. 2 cylinder 61, a rotating shaft 62 hinged on the frame 1 along the X-axis direction, and a material box 63 whose lower end is fixedly connected to the rotating shaft 62. The cylinder body of the No. 2 cylinder 61 is hinged on the frame 1, and the output end of the No. 2 cylinder 61 is hinged to the lower end surface of the material box 63, so that when the output end of the No. 2 cylinder 61 is extended, the material box 63 drives the rotating shaft 62 to rotate along the axis of the rotating shaft 62.

[0051] During actual use, the product is placed on a material box 63 in a horizontal state. When the bag 100 is opened, one end of the material box 63 is driven to rise by the No. 2 cylinder 61, so that the material box 63 rotates around the rotating shaft 62 and tilts toward the bag opening, pouring the product in the material box 63 into the bag 100.

[0052] In the above design, the structural design and specific implementation method of the flip mechanism 6 can effectively realize the rapid dumping of the product.

[0053] Specifically: Figure 5 As shown, the material box 63 includes a bottom plate 631, a baffle 632 arranged on the side of the bottom plate 631 and extending upward, and a material guide plate 633 arranged on the bottom plate 631 and extending obliquely downward. The side plate and the bottom plate 631 form a material storage trough with a material discharge port, and the material guide plate 633 is located below the material discharge port.

[0054] During actual use, the product is placed on the bottom plate 631 and is limited by the baffle 632. When the bottom plate 631 is tilted toward the bag opening, the product is guided by the guide plate 633 along the discharge port into the bag 100.

[0055] In the above design, the structural design and specific implementation method of the flap mechanism 6 can realize the dumping and guiding of the product.

[0056] The second embodiment provided by the present application is a packaging method, which adopts the packaging device of the product, the product is placed in the flip mechanism 6, the empty bag 100 is placed in the bag storage mechanism 2, the conveying mechanism 5 first drives the bag taking mechanism 4 to move to the bag storage mechanism 2 to take out an empty bag 100, and then the conveying mechanism 5 drives the bag storage mechanism 2 to move to the heat sealing mechanism 3. At this time, the opening of the empty bag 100 is located at the top, and then the flip mechanism 6 pours the product into the empty bag 100 and resets it, and then the heat sealing mechanism 3 heat seals the bag opening.

[0057] In the above design, plate-shaped and granular products can be quickly bagged and sealed, thereby improving work efficiency.
