Description

Technical Field

[0001] This invention relates to the field of packaging equipment technology, specifically to a multi-directional fully automatic carton packing machine specially adapted for use in integrated production lines. It can be widely used in carton packaging plants in the food, daily chemical, electronics, and logistics industries, and can be configured in various continuous production scenarios requiring carton packaging, such as fully automatic stapled and glued integrated machines and carton production lines, to achieve efficient collaborative packing operations with the production line. Background Technology

[0002] In modern industrial production processes, cardboard box packaging equipment, as a key terminal piece of equipment in the packaging production line, directly affects the overall production capacity and product delivery quality due to its operating efficiency, adaptability, and packaging quality. Therefore, it is widely used in various large-scale production enterprises. However, after long-term market research and practical application verification, it has been found that existing cardboard box packaging equipment still has many shortcomings that urgently need to be addressed, specifically in the following four core aspects:

[0003] Firstly, the adaptability of the packing direction is insufficient. Most current packing machines adopt a fixed packing direction design, usually only supporting a single straight packing mode. However, different customers have significant differences in production workshop layout and production line connection paths. Equipment with a single packing direction often cannot accurately match the actual production needs, requiring the additional construction of a conveyor transfer mechanism. This not only increases the equipment investment cost but also reduces the utilization rate of workshop space. At the same time, problems such as carton jamming during the transfer process may affect the continuity of production.

[0004] Secondly, the alignment effect of cardboard boxes is unstable. Existing alignment mechanisms mostly use a unidirectional mechanical drive structure, which can only align one side of the cardboard box, making it difficult to achieve omnidirectional, neat positioning. When dealing with cardboard boxes of different sizes and weights, problems such as misaligned corners, tilted boxes, and irregular stacking easily occur. The quality of the alignment effect directly determines the tightness and stability of subsequent packaging. Irregularly aligned cardboard boxes are prone to loose strapping and deformation after packaging, severely reducing packaging quality and potentially affecting the product protection during subsequent warehousing and transportation.

[0005] Third, the product protection performance is lacking. Traditional packaging equipment generally uses strapping for bundling. The strapping will generate a large local pressure during the tightening process. For cardboard boxes with soft body material and containing fragile or easily deformable products, the strapping is very likely to damage the box body or even cause the box to break, which will damage the internal products and increase production loss costs.

[0006] Fourth, the equipment lacks flexibility in use. Most existing packaging equipment has a fixed, integrated structure; its overall size and functional modules are pre-designed, making it impossible to flexibly combine and use it according to changes in production scale or adjustments to the production line layout. It is also difficult to separate it for use as an independent packaging device. This fixed design limits the applicable scenarios for the equipment. When a company's production needs change, existing equipment is often unsuitable, requiring the purchase of new equipment and increasing the company's production investment burden.

[0007] Given the numerous shortcomings of existing technologies, the industry urgently needs a fully automated packaging equipment with strong adaptability, high packaging quality, and good flexibility of use to meet the packaging needs of different production line layouts and product specifications, improve production efficiency and product protection, and reduce enterprise production input costs. Summary of the Invention

[0008] The purpose of this invention is to solve four core technical problems existing in current carton packaging machines: First, the single output direction makes it unable to adapt to different customer production line layouts, resulting in low space utilization; second, the carton alignment mechanism is ineffective, easily leading to misalignment and irregular stacking of cartons, resulting in a decline in packaging quality; third, traditional strapping packaging methods easily damage the carton body and break the internal products, resulting in poor product protection; and fourth, most of the equipment has a fixed integrated structure, which cannot be flexibly combined or used alone according to production needs, resulting in weak adaptability.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A fully automatic carton packing machine for a multi-directional packaging production line includes a frame, on which a aligning section, a conveying section and a packing section are sequentially arranged along the carton conveying direction.

[0011] The alignment section is equipped with a pneumatically driven omnidirectional alignment mechanism, which is electrically adjustable according to the carton specifications to adapt to cartons of different lengths and widths.

[0012] The conveying section adopts a conveying roller assembly driven by frequency conversion reduction, and each conveying roller is connected by a synchronous transmission structure;

[0013] The packaging section is equipped with a multi-directional packaging mechanism, which includes at least a left packaging unit, a right packaging unit, and a straight packaging unit. Each packaging unit can operate independently or in combination.

[0014] The packing section is equipped with a stretch film packing mechanism for fully wrapping the carton.

[0015] The fully automatic carton packing machine of the multi-directional packaging production line is connected to the carton production line to achieve coordinated linkage with the production line. It can be used in combination with similar equipment or used alone, and each piece of equipment is equipped with an independent control system.

[0016] Furthermore, the bottom of the frame is evenly equipped with multiple movable casters with locking function. The movable casters are made of wear-resistant rubber and are equipped with locking knobs. By rotating the locking knobs, the casters can be locked and unlocked.

[0017] Furthermore, the omnidirectional alignment mechanism includes at least two sets of vertically distributed pneumatic alignment components, namely a transverse alignment component and a longitudinal alignment component, and each set of pneumatic alignment components includes a cylinder and an alignment plate.

[0018] Furthermore, the multi-directional packaging mechanism is equipped with a column adjustment mechanism, which includes an adjustment column.

[0019] Furthermore, the independent control system is a PLC control system, which includes a PLC controller, a frequency converter module, and a control panel. The control panel is used to input parameters and control the operation of the equipment, and the frequency converter module is used to adjust the conveying speed of the conveying section.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0021] 1. Multi-directional output design enhances layout adaptability: With three independent output units (left, right, and straight output), the output direction can be flexibly selected according to different customers' production line layouts and workshop space planning. No additional transfer mechanism is required, which effectively improves the utilization rate of workshop space. At the same time, it adapts to different production line connection needs and enhances the versatility of the equipment.

[0022] 2. All-round alignment ensures packaging quality: The system uses multiple vertically distributed pneumatic alignment components to achieve all-round alignment of the carton in the length and width directions. At the same time, it is equipped with an electric adjustment mechanism to adapt to different sizes of cartons, which completely solves the problems of poor alignment effect and easy misalignment of cartons in existing equipment. This ensures the regularity of the cartons before packaging, provides a basic guarantee for high-quality packaging, and significantly improves packaging quality.

[0023] 3. Stretch film packaging enhances product protection: Replacing traditional strapping with full-wrap stretch film packaging avoids the localized high pressure caused by tightening strapping, which can damage the box. At the same time, the stretch film can fit tightly against the box, providing excellent protection for the box and the products inside, effectively reducing product damage caused by box breakage during transportation and storage, and reducing production losses.

[0024] 4. Flexible combination and independent control enhance scenario adaptability: The equipment supports combination with similar equipment or use alone. The configuration can be flexibly adjusted according to changes in production scale. At the same time, each piece of equipment is equipped with an independent control system, which can set parameters individually for different packaging needs, adapt to diverse production scenarios, reduce the equipment investment costs caused by changes in production needs, and improve the cost-effectiveness of equipment use.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0028] In the description of the embodiments of the present invention, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of the invention is in use, they are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention. Furthermore, terms such as "first," "second," and "third" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0029] Furthermore, the use of terms such as "horizontal," "vertical," and "sag" does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0030] In the description of the embodiments of the present invention, "multiple" means at least two.

[0031] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances.

[0032] This invention provides a fully automatic carton packing machine for a multi-directional packaging production line. The packing machine adopts a modular design and includes a frame 100 as the supporting foundation of the entire equipment. Multiple movable casters 101 with locking function are evenly arranged at the bottom of the frame 100. The movable casters can realize the convenient movement of the equipment. When the equipment is moved to the preset working position, the locking casters can realize the stable fixation of the equipment, ensuring that the equipment will not be displaced during operation.

[0033] The frame 100 is precisely equipped with a aligning section 2, a conveying section 3, and a packing section 4 arranged sequentially along the carton conveying direction. Each section is seamlessly connected via a precise mechanical positioning structure, ensuring smooth carton conveying between sections and preventing issues such as jamming or shifting. The specific structural design of each section is as follows:

[0034] Alignment section 2 is a specially configured pneumatically driven omnidirectional alignment mechanism. This alignment mechanism includes at least two sets of vertically distributed pneumatic alignment components, typically configured as a transverse alignment component 21 and a longitudinal alignment component 22. The transverse alignment component 21 is used to achieve alignment in the width direction of the carton, and the longitudinal alignment component 22 is used to achieve alignment in the length direction of the carton. The two sets of components work together to achieve omnidirectional alignment of the carton.

[0035] The conveying section 3 adopts a frequency-reduction driven conveying roller group 31. The conveying roller group 31 consists of multiple evenly arranged conveying rollers. Each conveying roller is connected by a synchronous transmission structure to ensure consistent rotation speed. The frequency-reduction drive mechanism can flexibly adjust the rotation speed of the conveying rollers according to the conveying rhythm of the front-end production line, so that the conveying speed of the conveying section is precisely matched with the output speed of the front-end production line, avoiding the accumulation of cartons or the discontinuity of conveying, and ensuring the continuity of production.

[0036] Packaging section 4, as the core functional section, is mainly equipped with a multi-directional packaging mechanism 41 and a stretch film packaging mechanism 42. The multi-directional packaging mechanism 41 specifically includes three independent packaging units: a left packaging unit, a right packaging unit, and a straight packaging unit. Each packaging unit is equipped with an independent drive component and guide structure. It can start a single packaging unit to achieve packaging in one direction according to actual production needs, or it can combine multiple packaging units to achieve packaging in multiple directions simultaneously. The stretch film packaging mechanism 42 replaces the traditional strapping packaging structure. It uses stretch film to fully wrap the neatly arranged carton, which can effectively improve the tightness and stability of the packaging, while avoiding damage to the carton. The multi-directional packaging mechanism 41 is equipped with a column adjustment mechanism 411. By adjusting the guide angle of the column, the accuracy of the packaging direction can be further optimized to ensure that the carton is discharged smoothly.

[0037] In addition, the packaging machine has good linkage adaptability and can be directly connected to various carton production lines to achieve collaborative operation. At the same time, it can be combined with multiple similar machines according to the needs of production scale. Each machine is equipped with an independent control system, which can realize independent parameter setting and operation control of a single machine, improving the flexibility and adaptability of the equipment. Specific implementation examples:

[0039] The following is in conjunction with the appendix Figure 1-2 The specific embodiments of the present invention are described in detail below. These embodiments are only for illustrating the technical solutions and do not limit the scope of protection.

[0040] like Figure 1-2 As shown, the frame of the baling machine in this embodiment is welded from high-strength steel, and four wear-resistant rubber casters with locking function are evenly installed at the bottom, which can be easily moved. After being moved to the designated position, it can be fixed by locking knob to prevent displacement during operation.

[0041] Alignment process: After the carton enters, the photoelectric sensor detects the signal and transmits it to the control system, which then activates the pneumatic alignment mechanism (one set of components each in the horizontal and vertical directions) to simultaneously advance the alignment plate and achieve all-round alignment. When adapting to different carton sizes, the operator inputs the size parameters through the control panel, and the control system automatically adjusts the spacing of the alignment components to ensure alignment accuracy.

[0042] Conveying section workflow: After the cartons are aligned, the end photoelectric sensor sends a signal, and the control system starts the stainless steel conveyor roller group (synchronous belt drive) driven by frequency conversion reduction, which smoothly conveys the cartons to the packaging section; the conveying speed can be adjusted by the frequency conversion module to match the rhythm of the front-end production line and avoid cartons piling up or becoming disconnected.

[0043] Packaging section workflow: After the carton enters, the stretch film packaging mechanism starts, the roll rotates and moves up and down with the lifting mechanism to achieve full wrapping packaging. The number of wrapping turns and tension can be set by the control system. After packaging is completed, the corresponding left, right and straight-out packaging units are started according to preset requirements. They can be operated individually or in combination. The packaging direction is optimized by the column adjustment mechanism to ensure stable material discharge.

[0044] Linkage and Control: The equipment connects to the carton production line via a communication interface to achieve collaborative operation; it can be combined with multiple similar equipment or used independently, and data interaction is achieved through bus communication; each equipment is equipped with an independent industrial-grade PLC control system, which is highly stable and resistant to interference. Operators can set various parameters individually through the control panel to achieve independent operation control.

[0045] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
