[0038] 1-3 , according to some embodiments of the present application, a box packing device 100 is provided, including a first conveying mechanism 10 and a second conveying mechanism 50. The first conveying mechanism 10 is used to convey a box body 200, and the second conveying mechanism 50 is used to convey materials. When the first conveying mechanism 10 conveys the box body 200 to below the unloading end 53 of the second conveying mechanism 50, the materials conveyed by the second conveying mechanism 50 can fall into the box body 200 on the first conveying mechanism 10, thereby realizing automated box packing.

[0039] The first conveying mechanism 10 includes a first conveying assembly 20 having a first conveying surface 21 for conveying the box 200. When the first conveying assembly 20 is in operation, it can drive the box 200 on the first conveying surface 21 to move, thereby conveying the box 200. Generally, the first conveying assembly 20 can be a conveying assembly such as a transmission roller assembly or a transmission belt assembly.

[0040] The second conveying mechanism 50 includes a second conveying assembly 52 for conveying materials, the second conveying assembly 52 is arranged at intervals above the first conveying surface 21, and the conveying downstream of the second conveying assembly 52 has a suspended unloading end 53. That is, the second conveying assembly 52 is arranged at intervals above the first conveying assembly 20, and the end of the conveying downstream of the second conveying assembly 52 is the unloading end 53. When the material is conveyed on the second conveying assembly 52, it is finally conveyed to the unloading end 53, and then falls from the unloading end 53 into the box body 200 on the first conveying surface 21, realizing automatic boxing.

[0041] Among them, along the conveying direction of the first conveying component 20, the first conveying surface 21 has a plurality of pause positions 22, and the pause positions 22 are used to pause the conveying of the box 200, that is, the box 200 can move under the drive of the first conveying component 20 until the box 200 moves to the pause position 22 and then stops moving. Moreover, the first conveying surface 21 is provided with a plurality of pause positions 22, and the box 200 can be paused at the plurality of pause positions 22 respectively, and can be paused multiple times. When the box 200 pauses at different pause positions 22, different areas of the box 200 receive the materials sent out by the unloading end 53. For example, when the box 200 pauses at the previous pause position 22, the front half of the box 200 close to the upstream of the transmission receives the materials sent out by the unloading end 53. After that, when the box 200 continues to move and pauses at the next pause position 22, the rear half of the box 200 close to the downstream of the transmission receives the materials sent out by the unloading end 53. In this way, both the front half and the rear half of the box 200 can receive the materials, and the inside of the box 200 can evenly receive and distribute the materials, so that the packing effect is better and the packing efficiency is improved.

[0042] The first conveying mechanism 10 includes a plurality of blocking components 30, which are arranged at intervals on the first conveying component 20 along the conveying direction of the first conveying component 20; the plurality of blocking components 30 sequentially block the box 200 conveyed on the first conveying surface 21, and a pause position 22 is formed at each blocking component 30. In other words, a plurality of blocking components 30 are arranged at intervals on the first conveying component 20, so that a plurality of pause positions 22 are formed by setting a plurality of blocking components 30, and the box 200 is blocked and paused at a plurality of different blocking components 30, so that the box 200 receives materials at different areas along the conveying direction, and the materials can be evenly distributed in the box 200.

[0043] Furthermore, each blocking component 30 has a blocking state protruding from the first conveying surface 21 and a releasing state exiting from the first conveying surface 21. Thus, when the blocking component 30 is in the blocking state, it protrudes from the first conveying surface 21, and can block the box 200, and the box 200 is blocked and paused at the blocking component 30, and the first half of the box 200 in the conveying direction is packed; when the blocking component 30 is in the releasing state, it exits from the first conveying surface 21, and no longer blocks the box 200, and the box 200 continues to move until it encounters the next blocking component 30, and the box 200 pauses again, and the second half of the box 200 along the conveying direction can be packed.

[0044] Furthermore, the initial state of each blocking assembly 30 is a blocking state, and along the upstream to downstream of the first conveying assembly 20, the plurality of blocking assemblies 30 are switched from the blocking state to the releasing state at their respective preset moments in turn, and a certain time interval exists between the two preset moments of each two adjacent blocking assemblies 30. In other words, the plurality of blocking assemblies 30 are switched at their respective preset moments, and a certain time interval exists between the preset moments of adjacent blocking assemblies 30, so that along the transmission direction of the box body 200, the box body 200 can be blocked and stay at each blocking assembly 30 for a certain time, so that the box body 200 can be dropped and packed into different areas of the box body 200 respectively, so as to realize uniform packing of the box body 200.

[0045] For example, from the upstream to the downstream of the first conveying component 20, the first blocking component 30 blocks the box 200 for a certain period of time and then switches from the blocking state to the releasing state at the first preset time. The box 200 is conveyed to the next blocking component 30 and is blocked for a certain period of time, and then switches from the blocking state to the releasing state at the second preset time. In this way, the box 200 pauses for a certain period of time at each blocking component 30 to achieve uniform packing of the box 200.

[0046] Specifically in some embodiments, the first conveying component 20 includes a bracket and a plurality of conveying rods arranged on the bracket. The plurality of conveying rods are arranged in parallel and spaced apart from each other. Each conveying rod can rotate around its own axis. The arrangement direction of the plurality of conveying rods is the conveying direction of the first conveying component 20. In this way, the box 200 on the first conveying surface 21 can be conveyed forward by the cooperation of the plurality of conveying rods.

[0047] The blocking assembly 30 includes a driving member 72 and a blocking member, wherein the driving member 72 is fixed to the bracket, and the blocking member is connected to the driving member 72, and can extend into between two adjacent conveying rollers and protrude from the first conveying surface 21 under the drive of the driving member 72 to block the conveyed box 200. In addition, the blocking member can also withdraw from the first conveying surface 21 and the gap between two adjacent conveying rollers under the drive of the driving member 72 to release the box 200. Optionally, the driving member 72 is a cylinder.

[0048] According to some embodiments of the present application, the second conveying mechanism 50 also includes a counting piece 54, which is arranged on the second conveying component 52 corresponding to the unloading end 53 and is used to count the amount of unloading, that is, the amount of material flowing to the unloading end 53 is counted by the counting piece 54, and then the amount of material delivered through the unloading end 53 can be obtained.

[0049] When the number of unloading materials reaches different preset unloading values, it is judged that different preset moments have been reached, that is, the number of materials received in the current box 200 is judged by the unloading value, and then different preset moments can be considered to have been reached when the number of unloading materials reaches different numbers. In this way, when the box 200 moves to the first blocking component 30 and the number of materials received reaches the first preset unloading value, it is judged that this is the first preset moment, and the blocking component 30 is switched from the blocking state to the release state, and the box 200 can continue to move to the next blocking component 30, and then continue to receive materials until the number of materials reaches the second preset unloading value, and it is judged that this is the second preset moment, and the blocking component 30 is switched from the blocking state to the release state, so that the box 200 continues to stay at different blocking components 30 for a certain period of time, and receives materials through different areas of the box 200, so as to achieve uniform boxing.

[0050] Optionally, the difference between two adjacent preset unloading values ​​is equal to the smallest preset unloading value among a plurality of different preset unloading values. That is, the box 200 pauses to accept the material of the first preset unloading value at the first blocking component 30, and the first preset unloading value is the smallest at this time. Subsequently, the box 200 pauses to accept the material at the second blocking component 30 until the material of the first preset unloading value is accepted again, and the second preset unloading value is reached at this time. The difference between the second preset unloading value and the first preset unloading value is equal to the first preset unloading value. This is equivalent to the number of materials accepted at each pause position 22 being the first preset unloading value, and the number of materials accepted at each pause position 22 being the same, so that the same number of materials can be arranged in different areas of the box 200, so that the materials are evenly distributed inside the box 200.

[0051] For example, there are multiple different preset unloading values ​​of 15 and 30. When the box 200 is conveyed to the first blocking component 30 for pause, when the front half of the box 200 along the conveying direction receives 15 materials, the first preset unloading value is reached, and the first blocking component 30 is switched from the blocking state to the releasing state, and the box 200 continues to move to the next blocking component 30 for pause. The rear half of the box 200 along the conveying direction receives materials. When the total number of received materials is 30, another preset unloading value is reached, and the front part of the box 200 also receives 15 materials. At this time, the box 200 as a whole completes uniform packing.

[0052] Referring to FIG. 2 and FIG. 4 , according to some embodiments of the present application, the second conveying mechanism 50 further includes a buffer assembly 70, which is disposed at one end of the second conveying assembly 52 having the unloading end 53 and includes a buffer element 71, and the buffer element 71 has a buffer position and a non-buffer position. When in the buffer position, the buffer element 71 docks with the unloading end 53 and is used to carry the material conveyed by the unloading end 53; when in the non-buffer position, the buffer element 71 is separated from the unloading end 53, allowing the unloading end 53 to unload the material, and at the same time, the buffer element 71 releases the material cached by itself for unloading.

[0053] In this way, a cache component 70 is set on the second conveying component 52, and the cache component 71 in the cache component 70 can be docked with the unloading end 53 to cache materials. In this way, during the time period when the current box 200 is full and waiting for the next box 200 to arrive at the first pause position 22, the material conveyed by the second conveying component 52 can be collected by the cache component 71, preventing the material on the second conveying component 52 from continuing to be conveyed and falling outside the box 200 in the gap of the switching box 200, thereby preventing material loss.

[0054] Furthermore, when the box 200 is switched into place, the cache member 71 can be switched to a non-cache position, at which time the materials collected in the cache member 71 can be released and all placed in a new box 200, while the unloading end 53 can continue to unload materials into the box 200 to continue packing the materials.

[0055] Specifically, the cache member 71 is controlled to switch to the cache state after the current box 200 passes through all the pause positions 22 and is full, and the cache member 71 is controlled to switch to the non-cache position when the next box 200 moves to the first pause position 22 among the multiple pause positions 22. In this way, when the current box 200 passes through all the pause positions 22 and is full, the packing of the current box 200 is completed. At this time, the cache member 71 is switched to the cache position and docked with the unloading end 53 to receive the material until the next box 200 moves to the first pause position 22 among the multiple pause positions 22, and the next box 200 moves into place. At this time, the cache member 71 is switched to the non-cache position, releasing the material collected by the cache member 71, and the unloading end 53 unloads the material to the box 200, starting a new round of packing. In this way, in the gap between switching two boxes 200, the material is received by the cache member 71, and the material will not fall outside the box 200, preventing material waste.

[0056] According to some embodiments of the present application, the cache component 70 further includes a driving member 72 and a transmission member 74, wherein the driving member 72 is fixedly disposed at one end of the second transmission component 52 having the unloading end 53, and the transmission member 74 is transmission-connected between the driving member 72 and the cache component 71; wherein the cache component 71 rotates relative to the unloading end 53 under the drive of the transmission member 74, and switches between a cache position and a non-cache position. In this way, a rotatable cache component 71 is provided, and the cache component 71 can rotate under the drive of the driving member 72 and the transmission member 74, and can rotate to dock with the unloading end 53, or rotate to separate from the unloading end 53.

[0057] Further, the second conveying assembly 52 includes a support assembly 521 and a second conveying member 523 disposed on the support assembly 521, and the second conveying member 523 has a material discharge end 53 downstream of its own conveying. The second conveying member 523 is a structure for conveying materials, such as a transmission belt or a plurality of transmission rollers, etc., which is not limited here.

[0058] Along the conveying direction of the second conveying member 523, the side frame of the bracket assembly 521 protrudes from the unloading end 53, and the side frame and the unloading end 53 enclose a unloading space 60, and the unloading space 60 has an unloading port facing the first conveying surface 21. When the buffer element 71 is in the buffering position, the buffer element 71 rotates until the buffer element 71 at least partially blocks the unloading port, so that the buffer element 71 and the unloading end 53 are docked. At this time, the material sent out from the unloading end 53 enters the buffer element 71 through the unloading port and is collected and cached by the buffer element 71. When the buffer element 71 is in the non-buffering position, the buffer element 71 rotates until the buffer element 71 exits the side of the unloading space 60 with the unloading port, and opens the unloading port, so that the buffer element 71 is separated from the unloading end 53, allowing the material to enter the unloading port and be unloaded into the box body 200 for boxing.

[0059] Furthermore, the buffer element 71 has a buffer space 711 and a notch 713 connected to the buffer space 711. When the buffer element 71 is in the buffer position, the notch 713 faces the second conveying member 523, and the buffer space 711 is connected to the material discharge space 60. When the buffer element 71 is in the non-buffer position, the notch 713 faces the first conveying surface 21. In this way, the buffer space 711 and the notch 713 are provided on the buffer element 71, so that the buffer space 711 can accommodate materials, and the notch 713 can also face the first conveying surface 21 to release the materials in the buffer space 711 for discharge.

[0060] Furthermore, the transmission member includes a first transmission rod 741 and a second transmission rod 743, the second transmission rod 743 is rotatably arranged on the side frame around a hinge point 76, the two ends of the second transmission rod 743 located on opposite sides of the hinge point 76 are respectively connected to the first transmission rod 741 and the cache member 71, and the end of the first transmission rod 741 away from the second transmission rod 743 is connected to the output end of the driving member 72. Driven by the driving member 72 and the first transmission rod 741, the second transmission rod 743 rotates around the hinge point 76 and drives the cache member 71 to rotate between the cache position and the non-cache position. In this way, the first transmission rod 741 drives the second transmission rod 743 to swing, and then drives the cache member 71 connected to the second transmission rod 743 to swing at the unloading end 53, so as to achieve the docking and separation of the cache member 71 and the unloading end 53.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
