Description

Technical Field

[0001] The present invention belongs to the technical field of packaging equipment, and particularly relates to case packing equipment. Background Art

[0002] The stand-up pouch structure is a bag structure that is narrow at the top and wide at the bottom. In the placed state, the stand-up pouch will be more significantly affected by the gravity of the material, and the structural difference between the narrow top and wide bottom will be more obvious because the material will accumulate at the bottom of the stand-up pouch. If the stand-up pouches are loaded into the carton in the spatial attitude when placed, the number of stand-up pouches that the carton can accommodate is limited; if more stand-up pouches are to be placed, the already placed stand-up pouches must be squeezed to make room, and such case packing operations are not conducive to mechanized operation and cannot load more stand-up pouches to improve the utilization rate of the carton. Summary of the Invention

[0003] Aiming at the defects of the prior art, the technical problem to be solved by the present invention is to provide a case packing equipment to ensure that more packaging bags can be loaded into the packaging box.

[0004] To solve the above technical problem, the present invention adopts the following technical solutions:

[0006] The lifting assembly includes a lifting driver and a lifting member driven by the lifting driver to lift; the mounting frame is connected to the lifting member, and the mounting frame is driven by the lifting member to perform linear motion in the vertical direction;

[0007] The flipping assembly is mounted on the mounting frame. The flipping assembly includes a flipping member and a flipping driver. The flipping member is connected to the load-carrying assembly, and the flipping driver drives the flipping member to drive the load-carrying assembly to perform an overall swing;

[0008] The load-carrying assembly includes a load-carrying frame for placing articles. The load-carrying frame is rotatably mounted on the flipping member. The load-carrying frame is provided with a blanking opening and a feeding opening, and the orientation of the blanking opening is perpendicular to the orientation of the feeding opening;

[0009] The movement range of the load-carrying frame of the connection and flipping device includes an unloading state where the blanking opening is vertically downward and a loading state where the blanking opening is horizontally oriented. The operating height of the load-carrying frame in the unloading state is lower than the operating height of the load-carrying frame in the loading state.

[0010] Preferably, a guiding plate is provided on the outer side of the load-carrying frame, and a guiding gap is provided between the guiding plate and the load-carrying frame.

[0011] Preferably, the loading assembly further comprises a supporting component, and the supporting component comprises a pallet rotatably mounted below the loading frame and a supporting driver, the pallet being driven to move by the supporting driver, and a movement range of the pallet intersecting with an area in front of the blanking opening.

[0012] Preferably, the loading frame includes a bottom plate that closes the bottom of the loading frame, a back plate that closes the back of the loading frame, and side plates that close the left and right sides of the loading frame, and a blanking opening is formed on the front side of the loading frame. The top of the loading frame is provided with a cover plate in a swinging manner, and the cover plate is driven by a cover plate driver installed on the loading frame to close the top of the loading frame or open the top of the loading frame, and a feeding opening is formed when the top of the loading frame is opened.

[0013] Preferably, a support platform is provided in the loading frame to assist the stand-up bag in unfolding in a horizontal position, the support platform is located on the back plate, and the support platform includes a lower inclined surface and a horizontal surface above the inclined surface.

[0014] Preferably, the flipping driver includes a swing servo motor, a reducer, and a swing arm, the flipping component is a connecting rod, the output end of the swing servo motor is connected to the input end of the reducer, one end of the swing arm is connected to the output end of the reducer, and the other end is movably connected to the connecting rod, and the connecting rod is connected to the loading assembly.

[0015] The present invention also provides a packing equipment, including the above-mentioned docking and flipping device, and also including an article conveying component, a carrying component, and a packaging box conveying component. The article conveying component is located above the packaging box conveying component. The article conveying component and the packaging box conveying component are both located on one side of the docking and flipping device. The packaging box conveying component is provided with a box pushing assembly. The docking and flipping device is in the same horizontal working plane as the packaging box conveying component in a loading state with the blanking opening horizontally oriented, and the blanking opening is located in the conveying direction of the box pushing assembly. The motion range of the working end of the carrying component includes above the working plane of the article conveying component and above the loading frame in the loading state, so as to carry the articles on the article conveying component to the loading frame.

[0016] Furthermore, the box packing device further comprises a box packing conveying component, which is located below the packing box conveying component and directly below the material drop opening in the unloading state. Furthermore, the packing box conveying component is provided with a box pushing component for pushing the packing box to the cargo frame.

[0017] The present invention also provides an article handling method, which includes an article conveying path, a packing box conveying path, a packing conveying path, and a connecting conveying path. The article conveying path, the packing box conveying path, and the packing conveying path are distributed in the horizontal direction, and the working height of the article conveying path is greater than that of the packing box conveying path, and the working height of the packing box conveying path is greater than that of the packing conveying path. The connecting conveying path is distributed in the vertical direction;

[0018] First, the article is conveyed to the working range of the connecting conveying path through the article conveying path, and the handling component handles the article and places it on the connecting conveying path. A horizontally placed packing box is conveyed on the packing box conveying path;

[0019] Second, after the connecting conveying path loads the article, it makes a descending conveying movement until the article is opposite to the packing box lying horizontally on the packing box conveying path, and the opening of the packing box faces the article;

[0020] Third, push the packing box until the packing box covers the article located on the connecting conveying path in a horizontal state;

[0021] Fourth, after the connecting conveying path loads the packing box and the article, it continues to make a descending conveying movement, and flips the packing box and the article above the packing conveying path, prompting the horizontally placed packing box to change its spatial posture and be in an upright state. Thus, after the article changes its spatial posture, it is loaded into the packing box, and the upright packing box is output outward through the packing conveying path.

[0022] Preferably, the articles on the connecting conveying path are stacked in a layered manner. The articles are divided into two groups in the stacking direction, and one group of stacked articles is arranged in a staggered manner with the other group of stacked articles in the reverse stacking direction.

[0023] The technical solution adopted by the present invention has the following beneficial effects:

[0024] When packing, first stack the packaging bags in the loading frame. After the stacking is completed, put the outer packing box on the loading frame, and support the packing box through the supporting member. Then, the whole loading component is turned downward through the flipping component. After the flipping is completed, the packing box is in an upright state. At this time, the lifting component descends to place the packing box stably. Finally, the supporting member no longer supports the packing box, and the lifting component drives the loading frame to rise, and the loading frame is separated from the packing box. At the same time, the packaging bags also separate from the loading frame and are transferred into the packing box. Since the stacked packaging bags in the loading frame are taken as a whole and are separated from the loading frame and transferred into the packing box at the same time, the shape of the packaging bags basically does not change before and after being transferred from the loading frame to the packing box. Since the structure of the loading frame can be designed according to the characteristics of different packaging bags to ensure that more packaging bags can be stacked in the loading frame, it also ensures that more packaging bags can be loaded into the packing box.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] Those skilled in the art will appreciate that, in the absence of conflict, the features in the following embodiments and implementations may be combined with each other.

[0040] The terms used in the present invention are only for the purpose of describing specific embodiments, and are not intended to limit the present invention. For example, the following words indicating orientation or positional relationship, such as "upper", "lower", "front", "back", "left", "right", etc., are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device / element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0041] In the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "fixation" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0042] refer to Figures 1 to 10As shown, a box packing device can be used for various articles, especially for box packing of packaging bags 201, including a docking and flipping device 1, an article conveying component 2, a handling component, and a packaging box conveying component 4. Among them, the article conveying component 2 is located above the packaging box conveying component 4, and the article conveying component 2 and the packaging box conveying component 4 are both located on one side of the docking and flipping device 1. The article conveying component 2 conveys articles to the docking and flipping device 1, and the handling component transfers the articles from the article conveying component 2 to the docking and flipping device 1 and stacks them. The packaging box conveying component 4 conveys the packaging box 401 and transfers it to the docking and flipping device 1, and the docking and flipping device 1 transfers the stacked articles into the packaging box 401 as a whole.

[0043] The docking and flipping device 1 includes a frame 10 and a lifting assembly 11, a mounting frame 114, a loading assembly 13 and a flipping assembly 12 installed on the frame 10. The loading assembly 13 and the flipping assembly 12 are both installed on the mounting frame 114. The lifting assembly 11 drives the mounting frame 114 and the loading assembly 13 and the flipping assembly 12 thereon to rise and fall, and the flipping assembly 12 drives the loading assembly 13 to flip on the mounting frame 114. The specific structure and working principle of the docking and flipping device 1 are described below by taking the packaging bag 201 as an example.

[0044] The lifting assembly 11 includes a lifting drive and a lifting component driven by the lifting drive to lift. The mounting frame 114 is connected to the lifting component. The mounting frame 114 is driven by the lifting component to make linear motion in the vertical direction. In this embodiment, the lifting drive includes a lifting servo motor 111, a screw 112, and a guide rod 113. The lifting servo motor 111 is connected to the screw 112 through a reducer. The screw 112 is parallel to the guide rod 113. The mounting frame 114 is slidably connected to the guide rod 113. The lifting component here is a screw sleeve. The screw sleeve is driven by the screw 112 to move up and down along the screw 112. The mounting frame 114 is connected to the screw 112 through the screw sleeve. After the screw 112 rotates, the mounting frame 114 can be driven to reciprocate linearly in the vertical direction through the screw sleeve, thereby driving the object-carrying component 13 and the flip component 12 carried on the mounting frame 114 to move up and down together. Of course, it can be understood by those skilled in the art that the above-mentioned lifting drive can also be replaced by a cylinder, an oil cylinder, etc.

[0045] The flipping assembly 12 includes a flipping member and a flipping driver. The flipping member is connected to the load-carrying assembly 13, and the flipping driver drives the flipping member, which drives the load-carrying assembly 13 to swing as a whole. In this embodiment, the flipping driver includes a flipping servo motor 121, a reducer 122, and a swing arm 123, and the flipping member is a connecting rod 124. The flipping frame 125 is swingably mounted on the mounting frame 114 through a swing shaft 1251. The output end of the flipping servo motor 121 is connected to the input end of the reducer. One end of the swing arm 123 is connected to the output end of the reducer, and the other end is movably connected to the connecting rod 124. The connecting rod 124 is connected to the load-carrying assembly 13 through the flipping frame 125. The spatial attitude of the flipping frame 125 is controlled by the flipping servo motor 121. The spatial attitude of the flipping frame 125 includes a vertical attitude and a horizontal attitude. Of course, those skilled in the art can understand that the above flipping driver can also be replaced by a cylinder, an oil cylinder, etc. For example, when it is a cylinder, the flipping member can be a connecting rod or a flipping block, and the piston rod of the cylinder is hinged to the flipping block, and the load-carrying assembly 13 is driven to swing as a whole by the telescopic movement of the piston rod.

[0046] The load-carrying assembly 13 includes a load-carrying frame 131 for placing the packaging bag 201. The packaging box 401 can be sleeved on the load-carrying frame 131. The load-carrying frame 131 is fixed to the flipping frame 125. The flipping frame 125 is rotatably mounted on the mounting frame 114. The load-carrying frame 131 is provided with a blanking opening and a feeding opening, and the orientation of the blanking opening is perpendicular to the orientation of the feeding opening. Corresponding to the spatial attitude of the flipping frame 125, the movement range of the load-carrying frame 131 includes an unloading state where the blanking opening is vertically downward and a loading state where the blanking opening is horizontally oriented. The working height of the load-carrying frame 131 in the unloading state is lower than the working height of the load-carrying frame 131 in the loading state, and the conversion of its working height is achieved through the lifting assembly 11. When the spatial attitude of the flipping frame 125 is a vertical attitude, the load-carrying frame 131 is in an unloading state with the blanking opening vertically downward. When the spatial attitude of the flipping frame 125 is a horizontal attitude, the load-carrying frame 131 is in a loading state with the blanking opening horizontally oriented. At this time, the packaging box 401 can be sleeved on and swing and lift together.

[0047] When the load-carrying assembly 13 swings, the packaging bag 201 placed in the load-carrying frame 131 is transferred into the packaging box 401. In order to enable the packaging bag 201 placed in the load-carrying frame 131 to be transferred into the packaging box 401 while keeping the whole state intact, the packaging box 401 is sleeved on the load-carrying frame 131. The load-carrying assembly 13 can be provided with a supporting member for supporting the packaging box 401, and the packaging box 401 sleeved on the load-carrying frame is supported by the supporting member. In the vertical attitude, correspondingly, the blanking opening of the load-carrying frame 131 faces downward, and the packaging box 401 is in an upright state. In the horizontal attitude, correspondingly, the blanking opening of the load-carrying frame 131 is horizontal, and the packaging box 401 is in a lying state.

[0048] Therefore, during packing, first place the packaging bags 201 in the load frame 131. After the placement is completed, put the packing box 401 over the load frame 131 and support the packing box 401 through the supporting member. Then, use the flipping assembly 12 to flip the entire load assembly 13 downward. After the flipping is completed, the packing box 401 is in an upright state. At this time, the lifting assembly 11 descends to place the packing box 401 stably. Finally, the supporting member no longer supports the packing box 401, and the lifting assembly 11 drives the load frame 131 to rise. The load frame 131 is separated from the packing box 401, and at the same time, the packaging bags 201 also separate from the load frame 131 and are transferred into the packing box 401. According to the description of the above packing process, since the stacked packaging bags 201 in the load frame 131 are regarded as a whole and are separated from the load frame 131 and transferred into the packing box 401 at the same time, the shape of the packaging bags 201 basically does not change before and after being transferred from the load frame 131 to the packing box 401. Since the characteristics of different packaging bags 201 can be considered, the structural design of the load frame 131 can ensure that more packaging bags 201 can be stacked in the load frame 131, thus also ensuring that more packaging bags 201 can be loaded into the packing box 401.

[0049] In this embodiment, the specific structure of the load frame 131 includes a bottom plate that closes the bottom of the load frame, a back plate that closes the back of the load frame, and side plates that close the left and right sides of the load frame. Therefore, a blanking opening is formed at the front side of the load frame.

[0050] Furthermore, a cover plate 132 that can be turned up and down is provided at the top of the load frame 131. For example, the cover plate 132 is movably installed at the top of the load frame 131 in a swinging manner. Specifically, it can be hinged and installed at the rear side of the back plate. The cover plate 132 is driven by a cover plate driver installed on the load frame 131 to rotate to close or open the top of the load frame. When the top of the load frame is opened, a feeding opening is formed. In this embodiment, the cover plate driver is a cover plate driving cylinder 1321. The cover plate driving cylinder 1321 is arranged at the rear side of the load frame 131, and the piston rod of the cover plate driving cylinder 1321 extends and retracts up and down to drive the cover plate 132 to rotate. After the cover plate 132 is turned up and opened, it is very convenient to place the packaging bags 201 into the load frame 131. After the packaging bags 201 are placed, the cover plate 132 can be turned down again to close the top of the load frame 131, which is beneficial to transfer the packaging bags 201 stacked in the load frame 131 to the packing box 401 through the blanking opening.

[0051] Further, a guiding plate 133 for guiding the packing box 401 to gradually push in from the blanking opening and externally sleeve on the outer side of the load-carrying frame 131 is provided on the outer side of the load-carrying frame 131. The guiding plate 133 is fixedly installed on the turnover frame 125, and a guiding gap is provided between the guiding plate 133 and the load-carrying frame 131. The two guiding plates 133 are correspondingly arranged on the left and right sides of the front part of the load-carrying frame 131, and an inclined surface for guiding is provided on the front side of the guiding plate 133. Corresponding side inclined surfaces 1313 are also provided on the side plates on the left and right sides of the load-carrying frame 131. The inclination directions of the two inclined surfaces are opposite, forming an "eight"-shaped opening. Taking the packing box as a cardboard box as an example, the opening of the cardboard box is closed by a hinge. In the natural open state, the position of the hinge is not completely fixed. Therefore, the "eight"-shaped opening structure formed by the inclined surface on the guiding plate and the inclined surface at the front part of the side plate of the load-carrying frame is beneficial to the entry of the hinge. It can be understood that packing box nesting spaces are provided between the bottom, left and right sides of the turnover frame 125 and the load-carrying frame 131 correspondingly, so that the packing box is basically completely externally sleeved on the load-carrying frame 131, and the blanking opening of the load-carrying frame 131 is close to the bottom of the packing box.

[0052] As Figure 5 shown, in this embodiment, the supporting member includes a tray 134 rotatably installed below the load-carrying frame 131 and a supporting driver. The tray 134 is driven to move by the supporting driver, and the movement range of the tray intersects with the area in front of the blanking opening. The supporting driver is a tray driving cylinder 1342. A rotating shaft 1252 is provided below the load-carrying frame of the turnover frame 125. Two V-shaped members 1341 are rotatably installed on the rotating shaft side by side through bushings. One side of the two V-shaped members is fixed to the tray 134, and the other side is connected with a pin shaft, and the pin shaft is connected with the piston rod of the tray driving cylinder 1342. After the packing box is externally sleeved on the load-carrying frame, the tray driving cylinder 1342 drives the tray 134 to rotate and support one side of the bottom of the packing box. Of course, the size of the tray is small, and it can only support a part of the packing box, and the bearing capacity is limited. Such a design is because the load-carrying frame will be close to the bearing surface after the packing box falls (that is, the conveying plane of the packing and conveying component mentioned in the following description), and it can be supported by the bearing surface after being separated from the tray 134.

[0053] Taking the self-standing bag as an example of the packaging bag, in order to load more self-standing bags to improve the utilization rate of the cardboard box, an auxiliary structure for assisting the self-standing bags to form more layers of stacking in the horizontal state is provided inside the load-carrying frame. The purpose is to make the self-standing bags unfold to form a state where the overall thickness tends to be uniform. In this way, after the self-standing bags are stacked, they can be filled in the limited area (after changing from the horizontal state to the vertical state, with the limitation of the cardboard box, the space filling effect brought by the stacked state can be maintained). Specifically, as Figure 6As shown, the auxiliary structure is a support platform located inside the object frame 131, and the support platform is located on the back plate. The support platform has an upper and lower structure, and the lower structure provides a support inclined surface 1311, and the upper structure provides a support horizontal surface 1312. Correspondingly, the self-supporting bag is also stacked in two layers, wherein the mouths of the multiple stacked self-supporting bags in the lower layer are supported on the support inclined surface 1311, and the mouths of the multiple stacked self-supporting bags in the upper layer are supported on the support horizontal surface 1312, so that the overall thickness of the self-supporting bag is relatively uniform after deformation, and obvious gaps between the self-supporting bags are avoided.

[0054] It is understandable that the specific structures of the lifting assembly 11, the object carrying assembly 13 and the flipping assembly 12 can be changed or replaced.

[0055] Continuous automated operation is achieved through the cooperation of the above-mentioned article conveying component 2, the handling component, the packaging box conveying component 4 and the docking and flipping device 1. The article conveying component 2 conveys the articles, and the handling component transfers the articles from the article conveying component to the loading frame 131. The movement range of the working end of the handling component includes the upper part of the working surface of the article conveying component and the upper part of the loading frame in the loading state, so as to transport the articles on the article conveying component 2 to the loading frame 131. The packaging box conveying component 4 conveys the packaging box horizontally, and the packaging box conveying component 4 is provided with a box pushing component 41. The docking and flipping device 1 is in the same horizontal working surface as the packaging box conveying component 4 in the loading state with the blanking opening facing horizontally, and the blanking opening is located in the conveying direction of the box pushing component 41. Therefore, under the action of the box pushing component 41, the packaging box 401 on the packaging box conveying component 4 is just pushed to the loading frame 131 and is covered on the loading frame 131.

[0056] In this embodiment, the transport component is a robot 3, and the packaging box conveying component 4 is a conveying surface constructed by rollers to carry and convey the packaging box 401, and the rollers are driven by chains.

[0057] Taking the packaging bag 201 as an example, the article conveying path provided by the article conveying component 2 conveys the packaging bag 201 to the position corresponding to the docking and flipping device 1. At this time, the docking and flipping device 1 is in the loading state with the blanking opening horizontally oriented and is in the same horizontal working plane as the packaging box conveying path provided by the packaging box conveying component 4, and the blanking opening is located in the conveying direction of the box pushing assembly.

[0058] Then the manipulator 3 grabs the packaging bag above the working surface of the article conveying component 2, and when it is transferred to the top of the loading frame 131 in the loading state, the manipulator 3 moves down and releases the packaging bag 201, and stacks the packaging bag 201 in the loading frame 131. In this embodiment, the article conveying component is a conventional conveyor belt, and the manipulator is a spider manipulator, which is provided with a suction cup 31, and grabs and releases the packaging bag 201 through the suction cup.

[0059] When the packing box 401 is conveyed to the position corresponding to the connecting and flipping device 1, the loading frame 131 rises to the height corresponding to the conveying plane of the packing box conveying component 4, that is, the connecting and flipping device 1 is in the same horizontal working plane as the packing box conveying component 4 in the loading state with the blanking opening horizontally facing. Therefore, the opening of the packing box 401 is directly opposite to the blanking opening of the loading frame in the horizontal state. The box pushing assembly 41 pushes the packing box 401 towards the loading frame 131. After being guided by the guiding plate 133, it finally sleeves on the outside of the loading frame 131.

[0060] As one of the implementable structures of the box pushing assembly 41 package, the box pushing assembly 41 includes a box pushing cylinder and a pushing plate, and the pushing plate is connected to the piston rod of the box pushing cylinder. In addition, the packing box conveying component 4 is also provided with a packing box stopping assembly 42. The packing box stopping assembly 42 includes a stopping cylinder and a stopping plate. The stopping plate is installed on the stopping cylinder, and the stopping plate also obtains guiding and limiting effects through the cooperation of a guide rod and a guide sleeve to realize up and down linear movement. In the initial state, the pushing plate is far away from the conveying area, the stopping plate located upstream is far away from the conveying area, and the stopping plate located downstream extends into the conveying area. The working area of the box pushing assembly is between the two packing box stopping units, and the distance between the two packing box stopping units is greater than the length of the packing box.

[0061] After the packing is completed, in order to realize the automatic conveying of the packing box 401 after the packing is completed, a packing conveying component 5 is also provided to receive the packing box 401 lowered from the connecting and flipping device 1 and convey it. The packing conveying component 5 is located below the packing box conveying component 4 and directly below the blanking opening in the unloading state, so as to correspond to the position where the packing box 401 falls from the connecting and flipping device 1. The packing conveying component 5 provides a packing conveying path. Therefore, after the loading frame 131 is flipped and lowered, the packing box 401 is exactly placed on the conveying plane of the packing conveying component 5.

[0062] The position of the connecting and flipping device 1 is fixed, and the conveying of the packaging bag 201, the stacking of the packaging bags 201 on the loading frame 131, the conveying of the packing box 401, the pushing of the packing box 401, and the flipping and lifting of the loading frame 131 in the connecting and flipping device 1 can be connected and carried out continuously. It provides a connecting conveying path and can fully realize the automation in the whole packing process.

[0063] Taking the packaging product as a stand-up bag and the packing box as a cardboard box as an example, the packing equipment in this embodiment is described as follows:

[0064] As Figure 1 and Figure 2As shown, during operation, the article conveying component 2 conveys stand-up pouches; the packing box conveying component 4 conveys cartons. The manipulator 3 places the stand-up pouches one by one into the loading frame 131. The stand-up pouches lie horizontally and are stacked. At the same time, after the carton is stopped by the stop plate, the upstream stop plate also extends into the conveying area, and the subsequent cartons in the conveying state are isolated without affecting the movement of the current carton.

[0065] As Figure 7 shown, after a sufficient number of stand-up pouches are placed in the loading frame 131, the cover plate 132 covers the top opening of the loading frame.

[0066] As Figure 8 shown, then, the push plate pushes the carton. The carton lies horizontally and the opening faces horizontally, so that the carton moves towards the position of the loading frame; the guiding plate 133 restricts the movement range of each flap of the carton, prompting the loading frame 131 to extend into the carton; then the support plate 134 swings upward, and the bottom of the carton is supported by the support plate. At the same time, the carton conveying component resets.

[0067] As Figure 9 and Figure 10 shown, the loading frame 131 is turned downward, and the spatial attitude of the carton changes to a state with the opening facing upward. Then, the connecting and flipping device 1 drives the carton and the stand-up pouches to move downward until the carton is placed on the packing and conveying component 5. The support plate 134 resets and no longer supports the carton. The loading frame rises and disengages from the carton. Finally, the stand-up pouches are loaded into the carton, and the connecting and flipping device 1 resets.

[0068] It can be seen that the article conveying path, the packing box conveying path, and the packing conveying path in the packing equipment are distributed in the horizontal direction, and the working height of the article conveying path is greater than that of the packing box conveying path, and the working height of the packing box conveying path is greater than that of the packing conveying path. The connection conveying path is distributed in the vertical direction. During operation, the article is conveyed through the article conveying path to the working range of the connection conveying path, and the handling component handles the article and places it on the connection conveying path. The packing box conveying path conveys the lying packing box. The articles on the connection conveying path are stacked in a layered manner. The articles are divided into two groups in the stacking direction, and in the opposite stacking direction, one group of stacked articles is arranged in a staggered manner with the other group of stacked articles, so as to stack more articles in a limited space. After the connection conveying path is loaded with articles, it makes a descending conveying movement until the article is opposite to the packing box lying on the packing box conveying path, and the opening of the packing box faces the article. Push the packing box until the packing box covers the article located on the connection conveying path in the lying state. After the connection conveying path is loaded with the packing box and the article, it continues to make a descending conveying movement, and flips the packing box and the article above the packing conveying path, prompting the lying packing box to change its spatial attitude and be in an upright state. Thus, the article is loaded into the packing box after changing its spatial attitude, and the upright packing box is output outward through the packing conveying path.

[0069] In summary, in this packing equipment, the article is automatically conveyed through the article conveying path, the packing box is automatically conveyed through the packing box conveying path. Corresponding to the connection conveying path, the handling component handles the article and places it on the connection conveying path. After the connection conveying path is loaded with the packing box and the article, it continues to make a descending conveying movement, and flips the packing box and the article above the packing conveying path, prompting the lying packing box to change its spatial attitude and be in an upright state. Thus, the article is loaded into the packing box after changing its spatial attitude, and the upright packing box is output outward through the packing conveying path, and the entire packing process can be fully automated.

[0070] As mentioned above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Those skilled in the art should understand that the present invention includes but is not limited to the content described in the above specific implementation manner. Any modification that does not deviate from the functional and structural principles of the present invention will be included in the scope of the claims.
