Description

Technical Field

[0001] The present invention relates to the technical field of packaging equipment, and in particular to an automatic product packaging line and a method thereof. Background Art

[0002] In the modern production process, packaging equipment, as an important machine for packaging products, not only protects the products, but also significantly improves the appearance of the products, thereby enhancing the market competitiveness of the products. Packaging machines are mainly divided into two categories according to their application scenarios and functional requirements: one is the assembly line type overall production packaging equipment, and the other is the equipment that focuses on the peripheral packaging of products. In actual applications, these two types of equipment have different structural designs and implemented functions according to specific packaging requirements to meet diverse and personalized packaging requirements.

[0003] With the continuous changes in market demand, especially in the field of food packaging, a new demand has emerged: filling pre-packaged and sealed products, that is, putting these packaged products into cans or containers. This filling method is not only convenient for subsequent packaging and transportation of products, but also provides convenience for consumers when eating, because the cans or containers can be used as temporary containers to directly hold products.

[0004] However, in current production practices, the filling process of bagged products is mostly completed by manual operation. Although there are various packaging equipment in the prior art, these equipment are not suitable for filling bagged products. The main reason is that the width of most bagged products in their natural state is usually larger than the diameter of the can or container, which makes it difficult for the packaging equipment in the prior art to fill bagged products and realize an automated and efficient filling process. Summary of the invention

[0005] Therefore, in order to solve the above-mentioned shortcomings, on the one hand, the present invention provides a product automatic packaging line, comprising: A bottle feeding unit drives a plurality of linearly arranged containers to move, and the moving direction of the containers is parallel to the arrangement direction of the containers. A turntable unit is provided on one side of the bottle feeding unit, and the turntable unit drives the containers to rotate along the central axis of the turntable unit; A pick-and-place unit, through which the container on the bottle-feeding unit is placed on the turntable unit; A canning unit, which bends and deforms the bagged product and delivers it into a container; The canning unit comprises a third power device and a clamping module, the clamping module is connected to the third power device, and the clamping module is driven to slide vertically by the third power device; The clamping module comprises: Fixed splint; Seventh power unit; A movable clamping assembly, which is arranged opposite to the fixed clamping plate and is connected to the seventh power device, and the movable clamping assembly is driven by the seventh power device to move linearly so as to move the movable clamping assembly closer to or away from the fixed clamping plate; The movable clamping assembly comprises: a movable clamping plate, which is arranged opposite to the fixed clamping plate and connected to the sixth power device; Arc plates, which are installed on both sides of the movable splint and are rotationally connected with the movable splint; The sixth power device drives the arc plate to rotate through the sixth power device.

[0006] The present invention drives the movable clamping assembly to move linearly through the seventh power device, so that the movable clamping plate and the fixed clamping plate clamp and fix the product. Then the sixth power device drives the arc plate to rotate to bend the two sides of the product, so that the width of the product is smaller than the diameter of the container mouth. The third power device drives the clamping module to slide vertically, so that the clamping module partially extends into the container. Finally, the sixth power device drives the arc plate to rotate in the opposite direction and the seventh power device drives the movable clamping assembly to move linearly, so that the movable clamping assembly releases the product, and the product slides into the container due to its own gravity, thereby realizing automatic canning of bagged products.

[0007] Furthermore, the pick-and-place unit includes: Eighth power unit; The ninth power unit; The bottle clamp is connected to the ninth power device, and the bottle clamp is driven to slide vertically by the ninth power device. The eighth power device drives the bottle clamp to move horizontally linearly, so that the bottle clamp moves back and forth between the bottle feeding unit and the turntable unit.

[0008] The container is clamped by the bottle clamp, the ninth power device drives the bottle clamp to rise, the eighth power device drives the bottle clamp to move horizontally, and then the ninth power device drives the bottle clamp to descend, and the bottle clamp releases the container, thereby realizing automatic transfer of the container.

[0009] Furthermore, the canning unit also includes a fifth power device, which drives the clamping module to move linearly along the first direction, so that the clamping module can reciprocate linearly between the material taking point and the canning point.

[0010] Furthermore, the canning unit also includes a fourth power device, which drives the clamping module to move horizontally linearly along a second direction, and the second direction is perpendicular to the first direction.

[0011] The fifth power device drives the clamping module to move back and forth linearly between the material picking point and the canning point, thereby realizing automatic transfer of products between the material picking point and the canning point, facilitating the clamping module to load products and avoiding interference. The fourth power device drives the clamping module to move linearly, thereby adjusting the position of the clamping module and improving the practical flexibility of the canning unit.

[0012] Furthermore, the automatic packaging line also includes a feeding unit, which is arranged at the material taking point and through which the product is sent to the canning unit; The feeding unit comprises: A first conveying device, wherein a plurality of partitions are provided on the first conveying device, and the plurality of partitions are arranged parallel to the conveying direction of the first conveying device to separate the first conveying device into a plurality of conveying channels; a second conveying device; The feeding channel includes a first channel and a second channel. The upper portion of the first channel is connected to a plurality of conveying channels. The middle portion of the first channel is linearly narrowed. The second channel is connected to a second conveying device. The first channel and the second channel are parallel to each other.

[0013] A plurality of small bags of products are fed into the feeding channel by the first conveying device; a large bag of products is fed into the feeding channel by the second conveying device. The feeding channel guides the movement of the bagged products so that the products move to a predetermined landing point. The guidance of the feeding channel allows the products to overlap with each other, making it easier to clamp and can multiple products, thereby improving packaging efficiency.

[0014] Furthermore, the automatic packaging line further comprises a baffle unit, which is arranged below the outlet end of the feeding channel; The baffle unit comprises: The first power unit; A baffle, which is arranged below the outlet end of the feeding channel and driven by the first power device to move horizontally and linearly; The second power device drives the baffle to slide vertically.

[0015] Before the product enters the feeding channel, the second power device will drive the baffle to rise, and then the first power device will drive the baffle to extend so that the baffle is at the outlet of the feeding channel. When the product enters the feeding channel and moves along the feeding channel to the upper surface of the baffle, the second power device will drive the baffle to slowly descend to prevent the product from slipping. After descending to a preset height, the seventh power device will drive the movable clamping assembly to move linearly so that the movable clamping plate and the fixed clamping plate clamp the product, and then the sixth power device will drive the arc plate to rotate to bend the two sides of the product. Through the above arrangement, the canning unit is given enough reaction time to clamp the product, so as to prevent the product from slipping to the ground before it is clamped and fixed.

[0016] Furthermore, the automatic packaging line also includes a material blocking unit, which is arranged at the canning point; The material blocking unit comprises: tenth power unit; The material-blocking rod is driven to slide vertically by the tenth power device.

[0018] When the movable clamping assembly releases the product, the tenth power device will drive the material-repelling rod to slide down, and the material-repelling rod will slide down to a preset height below the container mouth. Then the third power device will drive the clamping module to slide vertically up to a preset height. During this process, the product will be pushed into the container under the blocking action of the material-repelling rod, thereby preventing the product from being taken out of the container again due to the friction between the product and the clamping module.

[0019] Furthermore, the automatic packaging line also includes: A detection unit, which is arranged on the bottle feeding unit and through which the container image is acquired; A control unit obtains a container image, performs container height analysis based on the container image, obtains current container height data, performs difference calculation based on the current container height data and historical height data, obtains container height change data, performs stroke compensation calculation based on the height change data, obtains stroke compensation calculation results, and controls the lifting and lowering of the canning unit, the picking and placing unit, and the material resisting unit based on the compensation calculation results.

[0021] On the other hand, the present invention also provides a product automatic packaging method, the automatic packaging method uses the above automatic packaging line, and the automatic packaging method comprises: A plurality of empty containers are transported to the bottle feeding unit. Under the guidance of the bottle feeding unit, the plurality of empty containers form an orderly empty container column. The bottle feeding unit drives the empty container column to move.

[0027] As described in the background technology, in current production practices, the filling process of bagged products mostly relies on manual operation. Although there are various packaging equipment in the prior art, these equipment are not suitable for filling bagged products. The main reason is that the width of most bagged products in their natural state is usually larger than the diameter of the can or container, which makes it difficult for the packaging equipment in the prior art to fill bagged products and it is difficult to achieve an automated and efficient filling process.

Fig. 22 As shown, the third power device drives the clamping module to slide vertically so that the clamping module partially extends into the container. Finally, the sixth power device drives the arc plate to rotate in the opposite direction and the seventh power device drives the movable clamping assembly to move linearly, so that the movable clamping assembly releases the product, and the product slides into the container due to its own gravity, thereby realizing automatic canning of bagged products.

[0030] In this embodiment, the clamping module may also include a mounting portion 640, which is integrally mounted on the third power device.

The guidance of the feeding channel allows the products to overlap with each other, making it easier to clamp and can multiple products, thereby improving packaging efficiency.

[0040] Embodiment 3: During the feeding process, the clamping process of the clamping module has a certain delay, which is caused by the movement of the active clamping component. That is, the active clamping component clamps the product for a certain period of time, and during this period of time, the product moving out of the feeding channel may fall directly.

Fig.19As shown, when the product enters the feeding channel and moves along the feeding channel to the upper surface of the baffle, the second power device drives the baffle to slowly descend to prevent the product from sliding. After descending to a preset height, the seventh power device drives the movable clamping assembly to move linearly, so that the movable clamping plate and the fixed clamping plate clamp the product, and then the sixth power device drives the arc plate to rotate to bend the two sides of the product.

During this process, the product will be pushed into the container under the blocking action of the material-blocking rod, thereby preventing the product from being taken out of the container again due to the friction between the product and the clamping module.

[0047] like Fig.10 As shown, the material blocking unit may also include a support frame, through which the various structures of the material blocking unit are provided with installation space. For example, the above-mentioned eleventh power device is fixedly installed on the top of the support frame, the twelfth power device is installed at the bottom of the support frame, and the slide is slidably connected to the support frame.

[0050] In this embodiment, the container cover is placed in the cover storage slot with a preset orientation, and the rotating disk is driven to rotate by the fifteenth power device. The container cover rotates with the rotating disk. When it rotates to the guide plate position, the container cover gradually moves toward the third conveying device under the action of the guide plate, and is driven by the third conveying device to move to the end of the third conveying device, and then the container cover is taken out by the cover removing assembly and placed at the container mouth. The turntable unit drives the container to continue to rotate to the cap screwing unit, and the seventeenth power device drives the cover clamp to slide down.
