Description

Technical Field

[0001] This application relates to the technical field of packing items, and in particular to a box packing machine. Background Technology

[0002] Currently, after various items are produced, they need to be packaged and shipped in cardboard boxes. Since multiple items are placed inside these boxes, dividers are needed to prevent damage from collisions. The current method of placing dividers is manual, which is inefficient. Furthermore, the dividers are prone to tipping over after being placed inside the box, affecting the placement of items. Manual uprighting is required during packing, and the operator's hands can obstruct the box's opening, occupying space and hindering item placement, resulting in a slow and inefficient packing process.

[0003] Regarding the aforementioned technologies, the inventors believe that there are drawbacks such as the space occupied by packaging cartons and low packing efficiency. Summary of the Invention

[0004] In view of this, this application provides a case packing machine to prevent partitions from tipping over inside the case while reducing the space occupied inside the case and improving case packing efficiency.

[0005] This application provides a case packing machine, which adopts the following technical solution:

[0006] A case packing machine includes: a case packing platform for placing cardboard boxes containing items to be loaded;

[0007] A partition pick-and-place device includes a partition clamping mechanism, a pick-and-place driving mechanism, and a lifting driving mechanism. The lifting driving mechanism is connected to the partition clamping mechanism to drive the partition clamping mechanism to move upward or downward. The partition clamping mechanism includes a first clamping wire and a second clamping wire. The pick-and-place driving mechanism drives the first clamping wire and the second clamping wire to move closer to each other to clamp the partition, or drives the first clamping wire and the second clamping wire to move away from each other to release the partition.

[0008] By adopting the above technical solution, the first clamping wire and the second clamping wire can clamp the partition during the packing process and keep it upright so as not to tip over. This eliminates the need for manual support of the partition, avoids hands blocking the packing opening, improves packing efficiency, and uses wire-like materials to clamp the partition, thus occupying less space inside the box during the packing process.

[0009] Preferably, the partition clamping mechanism includes a first support plate and a second support plate, the first clamping wire is connected to the first support plate, the second clamping wire is connected to the second support plate, the first support plate and the second support plate are opposite to each other, the first clamping wire and the second clamping wire are parallel, and both ends of the first clamping wire and both ends of the second clamping wire are connected to the pick-and-place driving mechanism.

[0010] By adopting the above technical solution, even if the clamping wires are no longer clamping the partition after it is placed inside the box, it can still be supported by the support plate to prevent it from tipping over. The use of a flat support plate inside the box can reduce the space occupied in the box and does not affect the packing efficiency.

[0011] Preferably, both ends of the first clamping wire and both ends of the second clamping wire are connected to the pick-and-place driving mechanism. The first clamping wire and the second clamping wire are staggered vertically, and during the packing process, the axes of the first clamping wire and the second clamping wire are located in the same vertical plane.

[0012] By adopting the above technical solution, the first clamping wire and the second clamping wire are staggered vertically. During the packing process, the partition is clamped by the support plate. There is a height difference between the first clamping wire and the second clamping wire. The space occupied by the two clamping wires in the second direction is reduced to the space of one clamping wire, which shortens the distance between the two support plates and further reduces the space occupied.

[0013] Preferably, the partition clamping mechanism includes two first locking structures and two second locking structures. The first locking structure includes a first wire threading seat, a first adjusting member, and a first locking member. The first wire threading seat includes a first wire threading hole and a first threaded hole, which are connected. The first adjusting member includes a first stud and a second wire threading hole, which are connected to the first threaded hole. The first locking member includes a third wire threading hole and a second threaded hole, which are connected to the second threaded hole. The second threaded hole is connected to a fastening screw. The first steel wire passes through the first wire threading hole and the second wire threading hole and then enters the third wire threading hole. The fastening screw locks and fixes the first steel wire. The second locking structure includes a second wire threading seat, a second adjusting member, and a second locking member, and their structures are the same as those of the first wire threading seat, the first adjusting member, and the first locking member, respectively.

[0014] By adopting the above technical solution, the locking component pre-locks the clamping wire, so that the clamping wire will not be pulled away from the wire threading seat due to the gravity of the support plate during assembly. The adjusting component can tighten or loosen the clamping wire to facilitate rapid on-site assembly.

[0015] Preferably, the partition clamping mechanism includes a first silicone sleeve and a second silicone sleeve, the first silicone sleeve being coaxially sleeved with the first steel wire, and the second silicone sleeve being coaxially sleeved with the second steel wire, so as to clamp the partition through the first silicone sleeve and the second silicone sleeve.

[0016] By adopting the above technical solution, a silicone sleeve is set on the outer layer of the clamping wire, which can increase the friction between the wire and the partition and improve the clamping stability.

[0017] Preferably, the pick-and-place driving mechanism includes a first driving member, a linkage rod, a first pulley assembly, and a second pulley assembly. The first driving member is connected to the first pulley assembly, and the linkage rod is connected to the first pulley assembly and the second pulley assembly respectively. When the first driving member is activated, the first pulley assembly and the second pulley assembly drive synchronously in the same direction. The two ends of the first clamping wire are respectively connected to the upper belts of the first pulley assembly and the second pulley assembly, and the two ends of the second clamping wire are respectively connected to the lower belts of the first pulley assembly and the second pulley assembly. The upper belts and the lower belts drive in opposite directions.

[0018] By adopting the above technical solution, the synchronous operation of two pulley assemblies can be driven by a single drive component, realizing the clamping or releasing action of the clamping wire on the partition. The control is simple and the procurement and production cost of the parts is low.

[0019] Preferably, the partition removal and placement device further includes a cover support mechanism, which includes a first corner plate, a first support rod, a second corner plate, and a second support rod. The removal and placement driving mechanism drives the first support rod and the second support rod to move away from or closer to each other. The first corner plate is connected to the first support rod, and the second corner plate is connected to the second support rod. The first corner plate and the second corner plate are symmetrical and are used to open the cover of the packaging carton.

[0020] By adopting the above technical solution, the cover plates at both ends of the packaging carton in the width direction are restricted and supported to prevent them from tilting inward during the packing process and affecting the packing progress.

[0021] Preferably, the packing platform includes a base, a platform plate, and a first positioning mechanism. The first positioning mechanism includes a third driving member, a bidirectional transmission member, and two positioning side plates. The two positioning side plates are arranged opposite to each other and located on both sides of the platform plate along its length. The third driving member is connected to the bidirectional transmission member, and the bidirectional transmission member is connected to the two positioning side plates respectively. The third driving member drives the two positioning side plates to move back to back or towards each other through the bidirectional transmission member to loosen or fix the packaging carton.

[0022] By adopting the above technical solution, when the two positioning side plates come into contact with the packaging carton, they keep it stationary during the packing process. When the two positioning side plates separate from the packaging carton, they form a limit on both sides of the packaging carton, preventing it from shifting too much during transmission.

[0023] Preferably, the packing platform includes a second positioning mechanism, which includes a sensor, a positioning block, and a second cylinder. During the packing process, the positioning block protrudes from the platform plate to restrict the movement of the packaging carton. After packing is completed, the positioning block retracts to the bottom of the platform plate to eliminate the restriction on the packaging carton. The sensor is used to sense the positioning status of the packaging carton, and the second cylinder is used to drive the positioning block to extend or retract.

[0024] By adopting the above technical solution, the second positioning mechanism positions the packaging carton in the conveying direction, enabling it to accurately reach the packing station, which facilitates the positional correspondence with the partition clamping mechanism and the packing of goods.

[0025] Preferably, the system further includes a partition delivery device located at the rear of the packing platform. The partition delivery device includes a base box, a partition storage mechanism, an upper limit structure, and a rear limit structure. The partition storage mechanism includes an inclined support and a pallet rack. The inclined support is connected to the base box and tilts downward toward the packing platform. The pallet rack is connected to the inclined support and is used to store multiple partitions. The multiple partitions are stacked one by one along the tilt direction of the inclined support. The upper limit structure and the rear limit structure are connected to the inclined support and are used to limit the multiple partitions to maintain their vertical state.

[0026] By adopting the above technical solution, multiple partitions can be pre-stored for easy retrieval during item packing. By setting up inclined supports, the partitions can be moved downwards towards the packing platform, improving packing efficiency. The entire process of partition placement is automated, eliminating the need for manual transfer and improving packing efficiency.

[0027] The case packing machine provided by the embodiments of this application can automatically place partitions into the packaging carton and prevent the partitions from tipping over during the packing process, without the need for manual support, thereby reducing the space occupied at the packing opening and improving the efficiency of packing goods.

Detailed Implementation

[0040] To better understand the purpose, technical solutions, and advantages of this application, it has been described and illustrated below with reference to the accompanying drawings and embodiments. However, those skilled in the art should understand that this application can be implemented without these details. In some cases, to avoid obscuring various aspects of this application due to unnecessary description, well-known methods, processes, systems, components, and / or circuits already described at a higher level will not be elaborated upon. It will be apparent to those skilled in the art that various modifications can be made to the embodiments disclosed in this application, and the general principles defined in this application can be applied to other embodiments and application scenarios without departing from the principles and scope of this application. Therefore, this application is not limited to the illustrated embodiments, but conforms to the broadest scope consistent with the scope of protection claimed in this application.

[0041] It should be noted that the descriptions of these embodiments are for the purpose of aiding understanding the present invention, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0042] In the description of this application, "several" means one or more, "more than" means two or more, "greater than," "less than," and "exceeding" are understood to exclude the stated number, while "above," "below," and "within" are understood to include the stated number. The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0043] In the description of this application, the terms "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples.

[0044] This application discloses a carton packing machine for quickly packing various items into boxes. This application uses cardboard box packing as an example. Before packing, multiple cardboard boxes are typically divided into two groups, each group containing multiple boxes stacked on top of each other. The two groups of boxes are then placed into a packaging carton for shipment. A partition is needed between the two groups of boxes to prevent mutual abrasion. To prevent excessive shaking of the cardboard boxes during transportation, the internal space of the carton is not excessive. Its internal length and width dimensions are generally about 10mm larger than the length and width dimensions of the two groups of boxes. Therefore, when manually packing, holding the partition with one's hands can obstruct the packing opening and occupy space inside the carton, making packing difficult and resulting in low packaging efficiency.

[0045] Please refer to Figure 1 This application provides a case packing machine, which includes a feeding device 101 for conveying a carton 106 to a case packing station; a case packing platform 102 for placing and supporting the carton 106 and packing the items on the case packing platform 102, wherein the area for packing is the case packing station; a discharging device 103 for conveying the packed carton 106 away from the case packing machine; and a partition picking and placing device 104, which corresponds to the position of the case packing station, for picking up a partition 107 and placing it into the carton 106, so that the space inside the carton 106 is divided into two, and the two cartons to be packed are placed into the spaces on both sides of the partition 107 respectively. The feeding device 101 is connected to the packing platform 102 via a conveyor belt, which is connected to the conveying drive mechanism to realize the conveying action. The feeding device 101 includes a feeding sensor switch, which can sense the feeding status of the packaging carton 106. The discharging device 103 is equipped with a roller assembly, which can transfer the packaging carton 106.

[0046] Please refer to Figure 2 This is a perspective view of the partition loading and unloading device provided in this application embodiment. The partition loading and unloading device 104 includes a partition clamping mechanism 1, a loading and unloading drive mechanism 2, and a lifting drive mechanism 3. The lifting drive mechanism 3 is connected to the partition clamping mechanism 1 and can drive the partition clamping mechanism 1 to perform up and down lifting movements. The loading and unloading drive mechanism 2 is connected to the partition clamping mechanism 1 and can drive the partition clamping mechanism 1 to clamp or release the partition 107. The position of the partition clamping mechanism 1 corresponds to the loading opening of the packaging carton 106. Figure 2As shown, the partition clamping mechanism 1 includes a first clamping wire and a second clamping wire, which are used to clamp the partition. The pick-and-place driving mechanism 2 can drive the first and second clamping wires to move closer together to clamp the partition 107, or drive the first and second clamping wires to move away from each other to release the partition. When rising, the first and second clamping wires can clamp the partition 107; when falling, the partition 107 can be placed inside the packaging carton 106 while maintaining the clamping of the partition 107, so that during packing... During the process, the partition 107 inside the packaging carton 106 remains vertical and will not tilt or fall over, which facilitates the packing of the carton and eliminates the need for manual support of the partition 107, thus avoiding the occupation of internal space by human hands and improving packing efficiency. After the carton is packed, the partition clamping mechanism 1 can release the partition 107 and drive it to rise and leave the inside of the packaging carton 106 through the lifting drive mechanism 3, so as to avoid obstructing the packaging carton 106 from moving to the discharge device 103. At this time, the partition 107 is supported by the carton on both sides and will not tilt over.

[0047] In this embodiment, the lifting drive mechanism 3 drives the partition clamping mechanism 1 to rise and the pick-and-place drive mechanism 2 drives the first clamping wire and the second clamping wire to automatically clamp the partition 107. The partition clamping mechanism 1 is driven to fall so that the partition 107 is placed in the packaging carton 106. The partition clamping mechanism 1 clamps the partition 107 during the packing process, keeping the partition 107 in a vertical position without tilting, improving the smoothness of packing. The packing process does not require manual operation, improving packing efficiency. Moreover, the clamping wire is small in size, occupies little space, and does not hinder the packing of items.

[0048] In this embodiment, the left side of the packing platform 102 is a feeding device 101, and the right side is a discharging device 103. Packaging cartons 106 are conveyed from the feeding device 101 to the packing platform 102. In this embodiment, the conveying direction of the packaging cartons 106 is taken as the first direction, and when the packaging cartons 106 are placed on the packing station, their length direction is consistent with the first direction. In this embodiment, the width direction of the packaging cartons 106 is taken as the second direction.

[0049] like Figure 3As shown, the partition clamping mechanism 1 also includes a first support plate 111 and a second support plate 112. The first support plate 111 and the second support plate 112 are vertical flat plates, arranged opposite each other and parallel along a first direction. The first support plate 111 and the second support plate 112 are respectively connected to the pick-and-place driving mechanism 2 via a first clamping wire and a second clamping wire. They can move in opposite directions or towards each other under the drive of the pick-and-place driving mechanism 2. When they are close to each other, they can support the partition 107 to prevent it from tipping over. When they are far apart, they can release the partition 107. In this embodiment, the first support plate 111 and the second support plate 112 are positioned above the packaging carton 106 when rising and inside the packaging carton 106 when falling. The first support plate 111 and the second support plate 112 can be made of metal or plastic sheets. The first support plate 111 and the second support plate 112 disclosed in this embodiment have the same structural dimensions. In other embodiments, the structural dimensions of the first support plate 111 and the second support plate 112 may be different. By using a flat support plate connected to the clamping wires, the support plate can assist in supporting the partition when the clamping wires are holding it, thus improving clamping stability. When the partition 107 falls into the box, even if the clamping wires no longer hold the partition, the partition will not tip over due to the support plate. The support plate occupies little space inside the box during the packing process and does not affect the normal packing of items.

[0050] The first and second clamping wires disclosed in this application include, but are not limited to, wires such as steel wire, copper wire, iron wire or nylon rope that can clamp each other when they come into contact. The materials used for the two can be the same or different. In this embodiment, the first and second clamping wires are both made of steel wire. The first clamping wire is a first steel wire 113 and the second clamping wire is a second steel wire 114. The steel wires used as clamping wires to clamp the partition can ensure the clamping strength, and the small diameter of the steel wires can reduce the space occupied at the packing opening and not hinder the placement of items.

[0051] like Figure 2As shown, the first steel wire 113 and the second steel wire 114 are parallel, and both ends of the first steel wire 113 and the second steel wire 114 are connected to the pick-and-place drive mechanism 2, respectively. During the packing process, when the partition 107 is clamped, the first steel wire 113 and the second steel wire 114 are vertically opposite each other, and the axis of the first steel wire 113 and the axis of the second steel wire 114 are located in the same vertical plane. That is, when the partition is clamped, there is a height difference between the two steel wires, and one of the steel wires is located directly below the other steel wire. In this embodiment, the first steel wire 113 is positioned directly below the second steel wire 114. After the partition falls into the packaging carton, the partition 107 will be located below the first steel wire 113 and the second steel wire 114, and will no longer be in contact with the two steel wires. At this time, the partition 107 is supported or clamped by the first support plate 111 and the second support plate 112. When the partition 107 is clamped during the packing process, there is a height difference between the first steel wire 113 and the second steel wire 114. The space occupied by the two steel wires in the second direction is reduced to the space of one steel wire, which reduces the distance between the two support plates and further reduces the space occupied at the packing opening.

[0052] The first steel wire 113 and the second steel wire 114 are also provided with a first silicone sleeve and a second silicone sleeve (not shown in the figure). The first silicone sleeve is coaxially connected to the first steel wire 113, and the second silicone sleeve is coaxially connected to the second steel wire 114. The length of the first silicone sleeve and the second silicone sleeve can be equal to or greater than the length of the carton. When clamping the partition, the partition can be clamped by contacting the partition with the first silicone sleeve and the second silicone sleeve, which can improve the friction between the partition and the partition and improve the clamping stability.

[0053] The first support plate 111 and the second support plate 112 can be one piece or multiple pieces, such as... Figure 3 As shown, in this embodiment of the application, there are three first support plates 111 and three second support plates 112. These three support plates are spaced apart along the first direction, with the six support plates facing each other in pairs. By setting multiple support plates spaced apart, the clamping range of the partition 107 can be increased, and the weight is lighter compared to a single support plate with the same clamping range. Both the first support plate 111 and the second support plate 112 are provided with two wire-passing holes 115, located at both ends of the width direction of the support plate, which is the same as the first direction. Figure 3As shown, the first steel wire 113 passes through the first wire hole 115 from the front side of the first support plate 111 and wraps around to the rear side of the first support plate 111, then passes through the second wire hole 115 from the rear side, and so on, until the connection with the three first support plates 111 is completed. The second steel wire 114 passes through the first wire hole 115 from the rear side of the first second support plate 112 and wraps around to the front side of the second support plate 112, then passes through the second wire hole 115 from the front side, and so on, until the connection with the three second support plates 112 is completed. That is, the first steel wire 113 and the second steel wire 114 are positioned opposite each other when connected to the corresponding support plates, and by staggering them vertically, it can be ensured that the axes of the first steel wire 113 and the second steel wire 114 are in the same vertical plane during the packing process.

[0054] The three support plates are connected as one unit by steel wires, and the two ends of the steel wires are connected to the pick-and-place drive mechanism 2 to ensure that the three support plates can move synchronously. Figure 2 As shown, when packing items, they enter the packaging carton 106 through the upper packing openings on both sides of the partition 107. In this embodiment, steel wires are used to connect the items to the support plates, which can minimize the space occupied at the packing openings and avoid affecting the packing process. The first steel wire 113 and the second steel wire 114 have the same wire diameter, which can be 1mm. The thickness of the first support plate 111 and the second support plate 112 can be less than 1mm, for example, a 0.75mm thin metal plate, thus minimizing the overall space occupied.

[0055] like Figure 3 As shown, the partition clamping mechanism 1 also includes two first locking structures 12 and two second locking structures 13. The two first locking structures 12 and two second locking structures 13 are located above the packaging carton 106 and are respectively located at both ends in the first direction. The two ends of the first steel wire 113 are connected to the pick-and-place drive mechanism 2 through the two first locking structures 12, and the two ends of the second steel wire 114 are connected to the pick-and-place drive mechanism 2 through the two second locking structures 13. Figure 4 and Figure 5As shown, the first locking structure 12 includes a first threading seat 121, a first adjusting member 122, and a first locking member 123. One side of the first threading seat 121 is provided with a first threaded hole 1211. The first adjusting member 122 includes a first stud 1221 and a nut 1222. The first stud 1221 is connected to the nut 1222 and the first threaded hole 1211 in sequence. The nut 1222 is used to adjust the relative position between the first stud 1221 and the first threading seat 121. The first threading seat 121 has a first threading hole 1212, which communicates with the first threaded hole 1211. A second threading hole 1223 is provided through the central shaft of the first stud 1221, thus connecting the first threading hole 1212 to the second threading hole 1223 via the first threaded hole 1211. The first locking member 123 includes a third threading hole 1232, a second threaded hole 1231, and a fastening screw. The second threaded hole 1231 communicates with the third threading hole 1232, and the fastening screw is threadedly connected to the second threaded hole 1231. One end of the first steel wire 113 enters the first threading seat 121 through the first threading hole 1212 and exits through the second threading hole 1223, then enters the third threading hole 1232 and is locked in place by the fastening screw. The first threading seat 121 also has four mounting holes for connection and fixation with the pick-and-place drive mechanism 2. During the assembly of the first wire 113, the first wire threading seat 121 can be connected and fixed to the pick-and-place drive mechanism 2 firstly, and then the two ends of the first wire 113 can be passed through the corresponding first wire threading hole 1212 and second wire threading hole 1223 in sequence. Then the first stud 1221 is connected to the nut 1222 and the first threaded hole 1211, and the two ends of the first wire 113 enter the corresponding third wire threading hole 1232 respectively. The first wire 113 is pre-locked by the two first locking members 123 so that the first wire 113 will not come off the first wire threading seat 121. Then the first stud 1221 is screwed so that the end of the first stud 1221 moves toward the corresponding first locking member 123 and abuts against the first locking member 123. Finally, the nut 1222 is used to lock it, thereby tightening and fixing the two ends of the first wire 113. Pre-locking is achieved by the first locking member 123, ensuring that the first steel wire 113 will not detach from the first wire threading seat 121 due to the gravity pull of the first support plate 111 during assembly. The first adjusting member 122 can be used to tension or loosen the first steel wire 113, facilitating rapid on-site assembly. In this embodiment, the second locking structure 13 is the same as the first locking structure 12, that is, the second locking structure 13 includes the second wire threading seat 131, the second adjusting member, and the second locking member, which are the same as the first wire threading seat 121, the first adjusting member 122, and the first locking member 123, respectively, and will not be described again here.

[0056] Please continue to refer to this. Figure 4 and Figure 5The front end of the top surface of the first threading seat 121 is recessed downward to form a first step 1213, and the depth of the recess is the same as the height of the first step 1213. The first threading hole 1212 is opened from the chamfered surface of the first step 1213 and is inclined towards the first threaded hole 1211 until it is interconnected with the first threaded hole 1211. The second threading seat 131 is similarly configured, including a second step and a threading hole with the second step. In the embodiments of this application, the installation directions of the first locking structure 12 and the second locking structure 13 are different, such as... Figure 6 As shown, the bottom surface of the first wire threading seat 121 is connected to the pick-and-place drive mechanism 2, and the top surface of the second wire threading seat 131 is connected to the pick-and-place drive mechanism 2. The first step 1213 of the first wire threading seat 121 and the second step of the second wire threading seat 131 face each other but are at different heights, thereby creating a height difference between the first wire 113 and the second wire 114. That is, during the packing process, when the partition clamping mechanism 1 maintains the clamping state of the partition 107, the first step 1213 and the second step overlap, and the distance from the center of the first wire 113 to the bottom of the carton and the distance from the center of the second wire 114 to the bottom of the carton are different, resulting in a height difference between the two distances. In this embodiment, the first steel wire 113 is positioned lower than the second steel wire 114, meaning the distance from the first steel wire 113 to the bottom of the carton is less than the distance from the second steel wire 114 to the bottom of the carton. The height difference is equal to the thickness of the step. During packing, the first steel wire 113 is located directly below the second steel wire 114, reducing the space occupied by the two steel wires in the second direction to the space of one steel wire, further reducing the space occupied at the packing opening.

[0057] Please continue to refer to this. Figure 2 and Figure 3The pick-and-place drive mechanism 2 includes a frame 21, a first drive member 22, a linkage rod 23, a first pulley assembly 24, and a second pulley assembly. The first pulley assembly 24 includes a first drive pulley 241, a first driven pulley 242, and a first synchronous belt 243. The first synchronous belt 243 is engaged with the first drive pulley 241 and the first driven pulley 242 respectively. According to the positional relationship, the first synchronous belt 243 is divided into an upper belt 2431 and a lower belt 2432. The transmission directions of the upper belt 2431 and the lower belt 2432 are opposite. The second pulley assembly is the same as the first pulley assembly 24, and is respectively located on both sides of the width direction of the frame 21. The first driving pulley 241 and the second driving pulley are connected and driven by a linkage rod 23. The length direction of the frame 21 is the same as the first direction, and the width direction of the frame 21 is the same as the second direction, that is, the width direction of the frame 21 is the same as the width of the packaging carton 106. The first driving pulley 241 and the first driven pulley 242 are respectively located at both ends of the width direction of the frame 21. The first synchronous belt 243 and the second synchronous belt drive in the second direction. The first driving component 22 includes a first cylinder 221, a first connecting member 222 and a second connecting member 223. The first cylinder 221 is located below the first driving pulley 241, and its fixed end is connected to the first connecting member 222. The first connecting member 222 is connected to the frame 21. The telescopic end of the first cylinder 221 is connected to the second connecting member 223. The second connecting member 223 is connected to the lower belt 2432 of the first synchronous belt 243 through a belt component 244. When the first cylinder 221 extends and retracts, it drives the first synchronous belt 243 to move back and forth in the second direction. Consequently, the first driving pulley 241 and the first driven pulley 242 rotate synchronously, and the second driving pulley rotates synchronously through the linkage rod 23, thereby driving the second driven pulley and the second synchronous belt to rotate or move synchronously. This application can drive the synchronous operation of two pulley assemblies with a single driving component, realizing the relative or opposite movement of the first support plate 111 and the second support plate 112. The control is simple, and the procurement and production costs of the components are low.

[0058] The pick-and-place drive mechanism 2 also includes a first guide assembly and a second guide assembly. The first guide assembly includes a guide rail 251, a first slider 252, and a second slider 253. The guide rail 251 is connected to the upper surface of the frame 21, and its length direction is consistent with the second direction. The first slider 252 is connected to the first threading seat 121 and connected to the upper belt 2431 of the first synchronous belt 243 via a belt member 244. The second slider 253 is connected to the second threading seat 131 and connected to the lower belt 2432 of the first synchronous belt 243 via a belt member 244. The first slider 252 is close to the first drive wheel 241, and the second slider 253 is close to the first driven wheel 242. The first cylinder 221 extends. During movement, the lower belt 2432 drives the first driven wheel 242, and the upper belt 2431 moves towards the first driving wheel 241. At this time, the first threading seat 121 and the second threading seat 131 move away from each other as the corresponding sliders move, and the first support plate 111 and the second support plate 112 move away from each other, thus releasing the partition 107. When the first cylinder 221 retracts, the lower belt 2432 drives the first driving wheel 241, and the upper belt 2431 drives the first driven wheel 242. The first threading seat 121 and the second threading seat 131 move closer to each other as the corresponding sliders move, and the first support plate 111 and the second support plate 112 approach each other to clamp the partition 107. The second guide assembly has the same components and corresponding connection relationships as the first guide assembly, and the two are symmetrically arranged on both sides of the width direction of the frame 21.

[0059] When packing goods, the lid of packaging carton 106 is open and upright to facilitate packing. However, creases between the lid and the carton body make the lid prone to tilting inward, or it may tilt inward when the goods are bumped during packing, causing the packing opening to narrow and affecting the packing process. Figure 2As shown, the partition 107 clamping device provided in this application embodiment also includes a cover support mechanism 4, which is used to open the cover of the packaging carton 106 to prevent it from tilting inward so that the items can be packed. The cover support mechanism 4 includes a first corner plate 41, a first support rod 43, a second corner plate 42, and a second support rod 44. The first guide assembly and the second guide assembly both include a third slider 254 and a fourth slider 255. The length direction of the first support rod 43 is consistent with the first direction, and its two ends are respectively connected to the two third sliders 254. The first support rod 43 is close to the first drive wheel 241. The first corner plate 41 is connected to the first support rod 43. The inner corner of the first corner plate 41 faces the outer side of the packaging carton 106, and its vertical side plate extends towards the bottom of the packaging carton 106, so that its bottom is lower than the top of the cover plate. The two ends of the second support rod 44 are respectively connected to the two fourth sliders 255. The second corner plate 42 is connected to the second support rod 44. The second corner plate 42 is symmetrical to the first corner plate 41. The first corner plate 41 and the second corner plate 42 restrict and support the cover plates at both ends of the width direction of the packaging carton 106 to prevent them from tilting inward during the packing process and affecting the packing progress. In this embodiment, the first support rod 43 and the second support rod 44 are square strips, while in other embodiments they may be round rods.

[0060] like Figure 3 As shown, the third slider 254 of the first guide assembly is connected to the lower belt 2432 of the first synchronous belt 243 via the belt member 244, and the fourth slider 255 is connected to the upper belt 2431 of the first synchronous belt 243 via the belt member 244. The third slider 254 and the fourth slider 255 of the second guide assembly are similarly configured. When the first cylinder 221 extends, the lower belt 2432 drives the first driven wheel 242, and the upper belt 2431 moves towards the first driving wheel 241. At this time, the first support rod 43 and the second support rod 44 approach each other, and the first corner plate 41 and the second corner plate 42 do not contact the cover plates at both ends of the width direction of the packaging carton 106. When the first cylinder 221 retracts, the lower belt 2432 drives the first driving wheel 241, and the upper belt 2431 drives the first driven wheel 242. The first support rod 43 and the second support rod 44 move away from each other, and the first corner plate 41 and the second corner plate 42 contact the cover plates at both ends of the width direction of the packaging carton 106 and open the cover plates.

[0061] This application embodiment uses a single driving mechanism to simultaneously drive the partition clamping mechanism 1 to clamp the partition 107 and drive the cover support mechanism 4 to open the cover, or simultaneously drive the partition clamping mechanism 1 to release the partition 107 and drive the cover support mechanism 4 to leave the cover. Both functions can be achieved with a single control. The structure is compact, cost-saving, and easy to control, thus improving packing efficiency.

[0062] In other embodiments, the first drive element 22 may be a rotary motor connected to the first drive pulley 241, and the synchronous belt transmission is achieved by controlling the forward and reverse rotation of the rotary motor.

[0063] In other embodiments, the pick-and-place drive mechanism can be a bidirectional cylinder drive, with the first wire threading seat and the second wire threading seat respectively connected to two opposite telescopic shafts to bring the two steel wires closer or further apart.

[0064] Please refer to Figure 7 This is a schematic diagram of the lifting drive mechanism provided in the embodiments of this application. The lifting drive mechanism 3 includes a fixed base 31, a lifting base 32, a second drive member 33, a first transmission screw 34, and a third guide assembly 35. The second drive member 33 includes a motor 331, a third driving wheel 332, and a third driven wheel 333. The third guide assembly 35 includes a slide rail and a slider. The slide rail of the motor 331 and the third guide assembly 35 is connected to the fixed base 31. The lifting base 32 is connected to the first transmission screw 34 and the slider of the third guide assembly 35. The third driving wheel 332 is connected to the output shaft of the motor 331. The third driven wheel 333 is connected to the third driving wheel 332 via a belt. The third driven wheel 333 is connected to the first transmission screw 34. When the motor 331 operates, it sequentially drives the third driving wheel 332, the third driven wheel 333, and the first transmission screw 34 to rotate, thereby causing the lifting seat 32 to move up or down. The lifting seat 32 includes two push rods 321, which are clamped and connected to the linkage rod 23. The linkage rod 23 passes between the two push rods 321, thereby driving the partition clamping mechanism 1 to move up or down synchronously through the push rods 321. In some embodiments, the second driving member 33 can be a cylinder, which is connected to the lifting seat 32 through the cylinder's telescopic shaft to drive the lifting seat 32 to rise and fall.

[0065] Please refer to Figure 8The packing platform 102 includes a base 51, a platform plate 52, and a first positioning mechanism 53. The base 51 is connected to and supports the platform plate 52. The platform plate 52 is used to place the packaging carton 106. The base 51 and the platform plate 52 can be made of aluminum profiles and aluminum sheets. The first positioning mechanism 53 includes a third driving component 531, a bidirectional transmission component 532, and two positioning side plates 533. The two positioning side plates 533 are arranged opposite each other at both ends in the second direction. When the packaging carton 106 is located on the platform plate 52, the two positioning side plates 533 are respectively located on both sides of the width direction of the packaging carton 106. The third driving component 531 is connected to the two positioning side plates 533, and can drive the two positioning side plates 533 to move back to back or towards each other to leave or contact the packaging carton 106. When the two positioning side plates 533 contact the packaging carton 106, they clamp and position the sides of the packaging carton 106, keeping it stationary during the packing process. When the two positioning side plates 533 separate from the packaging carton 106, they limit the sides of the packaging carton 106, preventing it from shifting excessively during transport. The length direction of the two positioning side plates 533 is the same as the first direction, and their length is greater than or equal to the length of the platform plate 52, so that the packaging carton 106 is limited by the two positioning side plates 533 from the moment it enters the packing platform 102 until it leaves the packing platform 102 after packing. Two positioning side plates 533 are provided with guide plates 5331 at one end near the feeding device 101. The two guide plates 5331 form a funnel shape between them, which facilitates the guidance of the packaging carton 106 into the packing platform 102.

[0066] Please refer to Figure 9 The third driving component 531, like the second driving component 33, uses a motor and pulley; the similarities will not be repeated. The bidirectional transmission component 532 is a bidirectional screw, with its length direction the same as the second direction, but its two ends have different helical directions. Each end of the bidirectional screw is connected to two connecting rods 534, and each end of the two connecting rods 534 is connected to a fourth guide assembly 535. The fourth guide assembly 535 includes a slide rail and a slider, where the slider is connected to the base 51 of the packing platform 102. The two ends of the slide rail are connected to the connecting rods 534 and the positioning side plates 533, respectively. Thus, when the third driving component 531 operates, it drives the bidirectional screw to rotate. Due to the different helical directions at its two ends, the two positioning side plates 533 move in opposite directions, either back to back or towards each other, achieving separation from or contact with the packaging carton 106. By using one third driving component 531 to simultaneously drive two positioning side plates 533, the structure is compact, cost-effective, and easy to control, improving packing efficiency. In some embodiments, a bidirectional cylinder can be used as the third driving component instead of the bidirectional screw.

[0067] Please refer to Figure 10 and Figure 11The packing platform 102 also includes a second positioning mechanism 54, which is located at the bottom of the platform plate 52 and on the side near the discharge device 103. The platform plate 52 has a positioning opening, and the second positioning mechanism 54 is positioned corresponding to the positioning opening. The second positioning mechanism 54 includes a sensor 541, a positioning block 542, and a second cylinder 543 that drives the lifting positioning block 542 to rise and fall. When the packing process begins, the packaging carton 106 enters from the feeding device 101 and is conveyed to the packing platform 102, continuing to move towards the discharging device 103. Sensor 541 senses the arrival status of the packaging carton 106. When the sensor detects that the packaging carton 106 has reached the packing station, the second cylinder 543 drives the positioning block 542 to rise, blocking the movement of the packaging carton 106. At this point, it is confirmed that the packaging carton 106 has reached the packing station and the packing process can begin, so the conveying of the packaging carton 106 stops. After the packing is completed, the second cylinder 543 drives the positioning block 542 to descend and resumes the conveying of the packaging carton 106, allowing it to continue moving to the discharging device 103 to complete the packing process. The second positioning mechanism 54 positions the packaging carton 106 in the conveying direction, ensuring accurate arrival at the packing station and facilitating its alignment with the partition clamping mechanism 1, thus aiding in the packing process.

[0068] Please refer to Figure 12 and 13 This is a schematic diagram of the partition delivery device provided in this application embodiment. The partition delivery device 105 is located on the rear side of the packing platform 102, opposite to the lifting drive mechanism 3, and is used to deliver the partitions 107 above the packing station so that the partition clamping mechanism 1 can clamp them. The partition delivery device 105 includes a base box 61, a partition storage mechanism 62, an upper limit structure 63, a rear limit structure 64, and a partition delivery mechanism 65. The base box 61 is used to support the partition storage mechanism 62 and the partition delivery mechanism 65. The interior of the base box 61 can also serve as the main control box of the packing machine, housing various electrical components. Figure 12 and 13As shown, the partition storage mechanism 62 includes an inclined support 621 and a tray frame 622. The inclined support 621 is connected to the base box 61 and tilts downward toward the packing platform 102. In this application, the tilting direction of the inclined support 621 is taken as the third direction. The tray frame 622 is connected to the inclined support 621 and is used to store multiple partitions 107. The multiple partitions 107 are stacked one by one in the third direction. The upper limit structure 63 and the rear limit structure 64 can be indirectly or directly connected to the inclined support 621 to limit the multiple partitions 107 to maintain their vertical state. The tray frame 622 includes two symmetrically arranged L-shaped trays. The length direction of the two trays is consistent with the third direction. The two trays support the bottom of multiple partitions 107 and limit the left and right sides of the multiple partitions 107. The top of the front side of the first partition 107 is in contact with the upper limit structure 63 and is limited. The front end of the two trays is provided with a lower limit part. The bottom of the front side of the first partition 107 is in contact with the lower limit part and is limited. The back of the last partition 107 is limited by the rear limit structure 64. Thus, the multiple partitions 107 are restricted in all directions, and will not slide downward and detach themselves due to the tilt of the tray frame 622. The upper limit structure 63 includes a limit rod 631 and two limit components. The two ends of the limit rod 631 are connected to the bottom box 61 indirectly or directly. The limit components include a limit seat 632 and a limit member 633. The limit seat 632 is slidably connected to the limit rod 631. The distance between the two limit seats 632 can be adjusted to accommodate partitions 107 of different sizes. The limit member 633 includes an upper limit part and an adjustment part. The upper limit part is used to contact the top of the front side of the first partition 107 to limit the front end of the partition 107. The adjustment part includes a strip hole for connecting with the limit seat 632 and adjusting the height of the upper limit part to accommodate partitions 107 of different heights. The rear limiting structure 64 includes a rear limiting plate 641 and a first sliding assembly 642. The rear limiting plate 641 is used to contact the rear side of the last partition 107 for limiting. The first sliding assembly 642 is used to adjust the position of the rear limiting plate 641 to accommodate different numbers of partitions 107. When the pallet rack 622 is full of partitions 107, the rear limiting plate 641 moves to the position furthest from the packing platform 102, i.e., the highest position of the inclined bracket 621. As the number of partitions 107 decreases step by step, the rear limiting plate 641 also moves step by step towards the packing platform 102, always maintaining contact with the rear side of the last partition 107 for limiting. In this embodiment, the upper and lower parts are circular rods.

[0069] In this embodiment, multiple partitions 107 are pre-stored in the pallet frame 622 for easy access when packing items. By setting the inclined bracket 621, the partitions 107 move downwards towards the packing platform 102, thereby improving packing efficiency.

[0070] Please continue to refer to this. Figure 12 and13 The partition delivery mechanism 65 includes a third cylinder 651, a fifth guide assembly 652, a suction cup frame 654, and two suction cups 653. The fixed end of the third cylinder 651 is connected to the inclined bracket 621, the telescopic shaft of the third cylinder 651 is connected to the suction cup frame 654, the slide rail of the fifth guide assembly 652 is connected to the suction cup frame 654, the slider of the fifth guide assembly 652 is connected to the inclined bracket 621, and the two suction cups 653 can be connected to an external vacuum system. When delivering the partition 107, the two suction cups 653 are brought into contact with the front side of the first partition 107 and the air is drawn from the suction cups 653 so that the first partition 107 is firmly held by the two suction cups 653. The third cylinder 651 drives the suction cup frame 654 to extend towards the packing platform 102, so that the two suction cups 653 move the first partition 107 to the top of the packaging carton 106. The lifting drive mechanism 3 drives the partition clamping mechanism 1 to rise. The pick-and-place drive mechanism 2 is activated so that the first support plate 111 and the second support plate 112 clamp the partition 107. The vacuum system delivers gas to the two suction cups 653 so that they are released from the partition 107. The lifting drive mechanism 3 drives the partition clamping mechanism 1 to descend so that the partition 107 enters the carton along with the first support plate 111 and the second support plate 112, thereby completing the delivery of the partition 107. The partition 107 is automatically delivered to the partition clamping mechanism 1 by the partition delivery mechanism 65, and the whole process is automated, eliminating the need for manual transfer and improving packing efficiency.

[0071] The workflow of the case packing machine provided in this application embodiment can be as follows:

[0072] Multiple partitions 107 are placed on the tray 622 of the partition delivery device 105;

[0073] When the packaging carton 106 is placed on the feeding device 101, the feeding sensor switch detects that the packaging carton 106 has entered, the conveying mechanism starts to make the conveyor belt run towards the packing platform 102 to move the packaging carton 106. At the same time, the lifting drive mechanism 3 drives the partition clamping mechanism 1 to rise to avoid affecting the packaging carton 106 entering the packing station.

[0074] The second positioning mechanism 54 senses that the packaging carton 106 has arrived at the packing station, raises the positioning block 542 to block the movement of the packaging carton 106, and closes the conveying mechanism, so that the packaging carton 106 is paused at the packing station.

[0075] The lifting drive mechanism 3 drives the partition clamping mechanism 1 to descend and reset, so as to avoid affecting the operation of the partition delivery mechanism 65; at this time, the first cylinder 221 can be controlled to be in the extended state, so that the cover support mechanism 4 does not touch the carton cover when it descends, and the first steel wire 113 and the second steel wire 114 are far apart from each other.

[0076] The partition delivery mechanism 65 delivers the partition 107 to the top of the packing station. The lifting drive mechanism 3 drives the partition clamping mechanism 1 to rise, so that the partition 107 partially enters between the first steel wire 113 and the second steel wire 114. The first cylinder 221 is driven to retract, so that the first steel wire 113 and the second steel wire 114 approach each other to clamp the partition 107.

[0077] The partition delivery mechanism 65 releases the partition 107 and resets, the lifting drive mechanism 3 drives the partition clamping mechanism 1 to descend and reset, and the first steel wire 113 and the second steel wire 114 carry the partition 107 into the packaging carton 106.

[0078] Drive the first cylinder 221 to extend and release the partition 107. The partition 107 falls freely to the bottom of the packaging carton 106. The partition 107 is located below the first steel wire 113 and the second steel wire 114. The partition 107 is supported by the first support plate 111 and the second support plate 112 to prevent it from tipping over.

[0079] The first cylinder 221 is driven to retract, causing the first support plate 111 and the second support plate 112 to approach the clamping partition 107. The first steel wire 113 is located directly below the second steel wire 114, and the first corner plate 41 and the second corner plate 42 open the cover of the packaging carton 106.

[0080] Place the items into the spaces on both sides of the inner partition 107 of the packaging carton 106;

[0081] Drive the first cylinder 221 to extend so that the first support plate 111 and the second support plate 112 are separated, and the first corner plate 41 and the second corner plate 42 are separated from the cover plate. The lifting drive mechanism 3 drives the partition clamping mechanism 1 to rise away from the packaging carton 106.

[0082] The control positioning block 542 descends, the conveying mechanism starts, and the packaging carton 106 is transferred to the discharge device 103, and removed from the carton packer through the roller assembly of the discharge device 103.

[0083] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
