Description

Technical Field

[0001] The present invention relates to the field of packaging technology, and in particular to a packaging box stacking and grouping device, a cargo pallet separation and processing equipment, and an automatic loading device. Background Art

[0002] In the related technologies known to the inventor, most of them use suction cups to dismantle single boxes or whole layers and then re-stacking them, and there are also ways to use rolling shutters to place the whole layers. This packaging box stacking method is not widely adaptable. For example, the rolling shutter method requires the front end to dismantle the whole stack into single layers and then push them onto the rolling shutter. For example, suction cups to dismantle single boxes or whole layers have problems with stability and adaptability.

[0003] In the related art known to the inventor, when separating goods from pallets, the whole stack is rotated 180 degrees after being picked up by a forklift. At this time, the packaging box is located at the bottom and the pallet is located at the top, and the pallet can be directly extracted. Each stack of goods needs to be rotated 180 degrees, which takes a long time, and some products are not suitable for 180-degree inversion. In the process of rotating the goods to remove the pallet, the packaging box stack may become loose and the stability is not high.

[0004] Among the related technologies known to the inventors, automatic loading equipment is mostly suitable for loading bagged materials, but not for loading boxed materials. Some solutions suitable for loading boxed materials are mostly in the form of pallets, or robot single-box or multi-row loading mode, which is inefficient and the pallets take up a lot of space.

[0077] like Figures 1 to 7As shown, the embodiment of the present disclosure provides a packaging box stacking and grouping device 300. The packaging box stacking and grouping device 300 mainly includes a tilting mechanism 310, a first grouping conveyor 320 and a second grouping conveyor 330.

[0078] The tilting mechanism 310 includes a flipping frame 311. The tilting mechanism 310 includes a flipping frame 311, which is configured to be flippable around a horizontal axis to switch between a first working position and a second working position. The flipping frame 311 includes a first box stack bearing portion 3111 and a second box stack bearing portion 3112 that is at an angle to the first box stack bearing portion 3111. In the first working position, the first box stack bearing portion 3111 is horizontal, and the second box stack bearing portion 3112 is located above the first box stack bearing portion 3111; in the second working position, the second box stack bearing portion 3112 is horizontal, and the first box stack bearing portion 3111 is located above the second box stack bearing portion 3112.

[0081] The packaging box stacking and stacking device 300 of the disclosed embodiment can realize stacking, stacking, stacking and stacking of packaging boxes by tilting 90 degrees, and has high stability. The tilting action of the whole stack of packaging boxes is fast and efficient.

[0082] In the packaging box palletizing and grouping device 300 of some embodiments of the present disclosure, the first box pallet bearing portion 3111 is at right angles to the second box pallet bearing portion 3112, and the turning frame 311 is configured to be able to turn 90 degrees around the horizontal axis to switch between the first working position and the second working position.

[0083] In some embodiments of the packaging box stacking and stacking device 300, the tilting mechanism 310 further includes a flipping drive mechanism 312, which is drivably connected to the flipping frame 311 to drive the flipping frame 311 to flip. The flipping drive mechanism 312 is configured to drive the flipping frame 311 to flip, which is beneficial to achieving the degree of automation of the packaging box stacking and stacking device 300 and increasing the stacking capacity of the packaging box stacking and stacking device 300.

[0084] exist Figures 1 to 7 In the illustrated embodiment, the flip driving mechanism 312 includes a driving part and a transmission part, and the driving part is connected to the flip frame 311 through a transmission gear. The driving part can be, for example, a motor or a driving cylinder. The transmission part includes, for example, a transmission gear.

[0085] like Figure 7 As shown, in some embodiments of the packaging box stacking and grouping device 300, the first box stacking bearing part 3111 includes a plurality of first bearing beams arranged parallel to each other and perpendicular to the horizontal axis. The first grouping conveyor 320 includes a plurality of first conveying parts 321 arranged parallel to each other and perpendicular to the horizontal axis. At the first working position, the plurality of first bearing beams and the plurality of first conveying parts 321 are arranged alternately.

[0086] Referring to the arrangement of the first box stack bearing part 3111 and the first stacking conveyor 320, in some embodiments of the packaging box stacking and stacking device 300, the second box stack bearing part 3112 includes a plurality of second bearing beams arranged parallel to each other and perpendicular to the horizontal axis. The second stacking conveyor 330 includes a plurality of second conveying parts 331 arranged parallel to each other and perpendicular to the horizontal axis.

[0087] The above configuration of the first box stack bearing portion 3111 and the first group stacking conveyor 320 and the configuration of the second box stack bearing portion 3112 and the second group stacking conveyor 330 are conducive to reducing the occupied space of the packaging box stacking and stacking device 300, so that the structure of the packaging box stacking and stacking device 300 is compact.

[0088] In some embodiments, the first stacking conveyor 320 may include, for example, a first chain conveyor including a plurality of first chain conveying parts 321 arranged in parallel and at intervals and a first chain driving mechanism 322 , each of which is driven by the first chain driving mechanism 322 .

[0089] In some embodiments, the second stacking conveyor 330 may include, for example, a second chain conveyor including a plurality of second chain conveying parts 331 arranged in parallel and at intervals and a second chain driving mechanism 332 , each of which is driven by a second chain driving mechanism 322 .

[0090] like Figure 1 , Figure 5 and Figure 6As shown, in some embodiments, the packaging box stacking and stacking device 300 further includes a packaging box stacking buffer device. The packaging box stacking buffer device is configured to receive and buffer the packaging box stack G from the second stacking conveyor 330, and to convey at least part of the packaging box layer of the packaging box stack G thereon to the second stacking conveyor 330.

[0091] like Figure 1 As shown, in some embodiments of the packaging box stacking and stacking device 300, the packaging box stacking and buffering device includes a third stacking conveyor 340 and a pushing device 350. The third stacking conveyor 340 is configured to receive the packaging box stack G and buffer the packaging box stack G from the second stacking conveyor 330. The pushing device 350 is configured to push at least part of the packaging box layer of the packaging box stack G on the third stacking conveyor 340 to the second stacking conveyor 330.

[0092] like Figure 1 As shown, in some embodiments of the packaging box stacking and stacking device 300, the pushing device 350 includes a pushing member 351 and a pushing member driving mechanism 352. The pushing member 351 is arranged above the third stacking conveyor 340 in the transverse direction of the third stacking conveyor 340. The pushing member driving mechanism 352 is drivingly connected to the pushing member 351 to drive the pushing member 351 to reciprocate along the conveying direction of the third stacking conveyor 340.

[0093] The stacking device is used to participate in the stacking, and single-layer or multi-layer packaging boxes can be flexibly combined; it can adapt to a variety of stack shapes and has high stability.

[0094] In some embodiments, the third stacking conveyor 340 may include a roller conveyor, which includes a plurality of rollers 341 arranged side by side and a driving mechanism 342 for driving the rollers to rotate.

[0097] In some embodiments of the packaging box stacking and stacking device 300, the packaging box stacking and stacking device 300 further includes a tipping buffer mechanism 360, which is configured to buffer the tipping frame 311 when the tipping frame 311 switches between the first working position and the second working position.

[0098] The tipping buffer mechanism 360 can be configured in a variety of different forms. For example, the tipping buffer mechanism 360 can include any one or more components that can achieve a buffering function, such as a buffer spring, a buffer pad, a cylinder or an oil-gas cylinder. Before the flip frame 311 moves to the first working position or the second working position, the tipping buffer mechanism 360 gradually slows down the rotation speed of the flip frame 311, so that the flip frame 311 can be smoothly switched to the corresponding working position. This setting is conducive to preventing the various components of the packaging box stacking and stacking device 300 from colliding with each other, thereby helping to reduce equipment noise, preventing the items in the packaging box stack G from being damaged, and also helping to increase the service life of the packaging box stacking and stacking device 300.

[0099] The packaging box palletizing and stacking device 300 of this embodiment further includes a stacking device frame 370, and the tipping machine 310, the first stacking conveyor 320, the second stacking conveyor 330, the third stacking conveyor 340, and the pushing mechanism 350 are all arranged on the stacking device frame 370.

[0103] The first stack of whole packaging boxes G is transported to the first stacking conveyor 320 via an external docking device (such as the packaging box stack extraction device 100 described later). After the first stack of whole packaging boxes G is transported to abut against the second stacking support portion 3112, the whole stack of packaging boxes G is flipped 90 degrees by the tilting mechanism 310, and the whole stack of packaging boxes G is tilted onto the second stacking conveyor 330 under the support of the second stacking support portion 3112. The first stack of whole packaging boxes G is transported to the third stacking conveyor 340 via the second stacking conveyor 330 for material preparation, waiting for the next step of stacking and stacking.

[0104] The second stack of packaging boxes G is tipped over onto the second stacking conveyor 330 in the same manner as the first stack of packaging boxes G, waiting for the separated packaging boxes G to come over for stacking.

[0105] Pushing and stacking. After the first stack of complete packaging box stack G and the second stack of complete packaging box stack G are ready, the pushing drive mechanism pushes the first stack of complete packaging box stack G to approach the second stack of complete packaging box stack G, and the required moving distance is determined according to the number of layers required to be stacked. After reaching the required moving distance, the stacking process is completed. At this time, the packaging boxes located on the second box stack bearing portion 3112 are ready to form the reassembled packaging box stack G.

[0106] The packaging boxes that are divided from the first stack of packaging boxes G onto the second box stack bearing portion 3112 are continuously pushed by the second stacking conveyor 330 toward the first box stack bearing portion 3111, and finally abut against the second stack of packaging boxes G, completing the stacking process with the second stack of packaging boxes G. The reassembled packaging box stack G is flipped and erected by the tilting mechanism 310, and can then be output by the first stacking conveyor 310.

[0107] The packaging box stacking process of the packaging box stacking and stacking device 300 of the embodiment of the present disclosure can refer to the stacking process, except that the second stack of packaging box stacks G does not need to participate, which will not be described in detail here.

The single vertical pallet conveyor 410, the pallet transfer mechanism 420, the pallet flipping mechanism 430, the single horizontal pallet conveyor 440, the pallet stacking mechanism 450 and the stacking horizontal pallet conveyor 460 are all arranged on the pallet collection device frame 470. The pallet collection device frame 470 can be set as an integrated or split structure as needed.

[0120] The single vertical pallet conveyor 410 may be, for example, a roller conveyor or a chain conveyor. In order to prevent the vertical pallet T from tipping over, anti-tipping devices may be provided on both sides of the conveying passage. The anti-tipping devices may include fences or a plurality of vertical rollers provided on both sides of the conveying passage.

[0121] The pallet transfer mechanism 420 can be implemented in many ways. For example, the pallet can be transferred from the packaging box palletizing and grouping device 300 to the single-unit upright pallet conveyor 410 by a clamping device, a suction cup device, a pushing device or a pulling device.

[0122] like Fig. 9As shown, in this embodiment, the tray transfer mechanism 420 includes a driving mechanism 421, a transmission mechanism 422, a drag member guide rail 423 and a drag member 424. The driving mechanism 421 includes, for example, a motor, and the transmission mechanism 422 includes, for example, a sprocket and a chain arranged on the sprocket, and the motor drives the sprocket to rotate. The chain is connected to the drag member 424. The drag member 424 is arranged along the drag member guide rail 423 to be reciprocatingly movable. The drag member is used to cooperate with the tray T to drag the tray T to move.

[0123] In this embodiment, the dragging member 424 includes a slider that slides with the dragging member guide rail 423 and a hook that is rotatably arranged on the slider, and may also include a hook driving part that drives the hook to rotate, and the hook driving part is, for example, a motor or a driving cylinder. The hook can be switched to different working positions by rotating the hook, such as Fig. 9 As shown in FIG. 1 , the hook is rotated to be perpendicular to the guide rail 423 of the dragging member, and then the first working position can be used to pull the tray T. In the first working position, if the hook is located on the side of the tray T away from the tray turning mechanism 430, the tray T can be pulled toward the tray turning mechanism 430. When the hook is rotated to an angle less than a certain range with the guide rail 423 of the dragging member, as shown in FIG. Fig. 9 When it is located above the tray T as shown, it is in the second working position for avoiding the tray T.

[0124] like Fig.10 As shown, the pallet flipping mechanism 430 includes a pallet carrier 431 and a pallet flipping driving mechanism 432. The pallet carrier 431 has a first pallet bearing portion and a second pallet bearing portion spaced apart from the first pallet bearing portion. The pallet flipping driving mechanism 432 is drivingly connected to the pallet carrier 431 to drive the pallet carrier 431 to rotate between a vertical first working position and a horizontal second working position. In the first working position, the first pallet bearing portion is close to the pallet stacking mechanism 450, and the second pallet bearing portion is away from the pallet stacking mechanism 450; in the second working position, the first pallet bearing portion is located below the second pallet bearing portion.

[0125] In some embodiments, the tray flipping drive mechanism 432 includes a drive cylinder. In other embodiments, the tray flipping drive mechanism may include a motor.

[0126] The pallet T can be transported between the first pallet carrying portion and the second pallet carrying portion by the single-unit vertical pallet conveyor 410 and / or the pallet transfer mechanism 420, and then carried on the pallet carrier 431. Afterwards, the pallet flipping drive mechanism 432 drives the pallet carrier 431 to rotate from a vertical state to a horizontal state, and the pallet T can be driven by the pallet carrier 431 to rotate to a horizontal state.

[0127] like Fig.10As shown, after the pallet T is turned to the horizontal position, it will be carried on the single horizontal pallet conveyor 440 and transported by the single horizontal pallet conveying device to the pallet stacking mechanism 450 located downstream.

[0128] In some embodiments, the single horizontal pallet conveyor 440 may be a roller conveyor or a chain conveyor, etc. The first pallet bearing portion is configured to avoid the conveying surface of the single horizontal pallet conveyor 440 after the pallet carrier 431 turns horizontal, so that the horizontal pallet T falls on the conveying surface of the single horizontal pallet conveyor 440. For example, the first pallet bearing portion may include two supporting beams located outside the conveying surface of the single horizontal pallet conveyor 440 when in the second working position. In some embodiments, the first pallet bearing portion and the single horizontal pallet conveyor 440 may also be configured in a similar arrangement to the arrangement of the first box stack bearing portion 3111 of the flip frame 311 of the aforementioned packaging box stacking and grouping device 300 and the first grouping conveyor 320.

[0129] like Fig.10 As shown, the pallet stacking mechanism 450 includes a pallet lifting platform 451, a lifting drive mechanism 452 and a supporting mechanism not shown in the figure. The pallet lifting platform 451, for example, includes a scissors-type structure and a supporting platform arranged on the top of the scissors-type structure. The lifting drive mechanism 452, for example, includes a driving cylinder. The driving cylinder is connected to the scissors-type structure to drive the supporting platform to lift and lower. When it is necessary to receive the pallet T, the supporting platform rises, lifts up the pallet stack on it, and the pallet stack is supported by the supporting mechanism, and then the supporting platform falls, and a vacant space appears between the pallet stack and the supporting platform. The single horizontal pallet conveyor 440 can convey the pallet T on it to the vacant space, and then stack the pallet stack supported by the supporting mechanism on the pallet T on the vacant space. By analogy, the stacking of pallets can be achieved.

[0130] The support platform may have a conveying function, for example, the support platform may be a roller conveyor platform or a chain conveyor. When the number of stacked pallets T reaches a predetermined amount, a required pallet stack is formed, and the support platform may convey the pallet stack downstream. In this embodiment, the support platform conveys the pallet stack to the whole stack horizontal pallet conveyor 460. The whole stack horizontal pallet conveyor 460 may be, for example, a roller conveyor.

[0131] The following is a detailed description of the action process of the cargo pallet separation and processing equipment of this embodiment. The main action process includes the whole stack tipping separation, pallet extraction, pallet 90 degree rotation and pallet stacking.

[0132] The stack of packaging boxes G with pallets is tilted and separated. The whole stack of packaging boxes G is transferred to the first stacking conveyor 320 via the external docking equipment, and the first stacking conveyor 320 conveys the whole stack of packaging boxes G close to the first stack bearing part 3111 of the turning frame 311. The whole stack of packaging boxes G is tilted 90 degrees along with the turning frame, and falls onto the second stacking conveyor 330 with the support of the second stack bearing part 3112. The second stacking conveyor 330 drives the tilted whole stack of packaging boxes G to move a small distance, so that a certain distance is opened between the whole stack of packaging boxes G and its pallet T and the second stack bearing part 3112, and the tilting of the whole stack of packaging boxes G and the separation of the pallet T are completed.

[0133] Pallet extraction. The pallet transfer mechanism 420 moves close to the upright pallet T, and the dragging member 424 of the pallet transfer mechanism 420 moves to cooperate with the upright pallet T. Driven by the pallet transfer mechanism 420, the pallet T moves along the single upright pallet conveyor 410 to the single upright pallet conveyor 410, completing the extraction of the pallet T from the whole stack of packaging boxes G, and then is transferred by the single upright pallet conveyor 410 to the pallet carrier 431 of the pallet flipping mechanism 430.

[0134] The pallet rotates 90 degrees. The pallet carrier 431 of the pallet flipping mechanism 430 rotates 90 degrees around the rotation axis under the action of the pallet flipping driving mechanism 432, driving the pallet T to rotate from the vertical state to the horizontal state. The pallet T turned to the horizontal state is placed on the single horizontal pallet conveyor 440.

[0135] Pallet stacking. The pallet stacking mechanism 450 is activated to form an empty space between the support platform and the stacked pallets. The single horizontal pallet conveyor 440 conveys the pallet T into the empty space of the pallet stacking mechanism 450, and the pallet stacking mechanism 450 completes the stacking of the horizontal pallets T. The stacked pallets are transferred to the whole-stack horizontal pallet conveyor 460, and are taken away by a forklift or directly transported to the docking external conveyor line.

[0136] The cargo pallet separation and processing equipment of the present embodiment has at least one of the following advantages: it is highly flexible and can remove the pallet T after the stack of packaging boxes G with the pallet is overturned. The second group of stack conveyors 330 can move the entire stack of packaging boxes G a short distance after the stack of packaging boxes G with the pallet is overturned, thereby reducing the resistance to the removal of the pallet, and can flexibly and quickly realize the removal of the pallet T; at the same time, after the pallet is removed, the entire stack can be moved in the opposite direction to approach the second box stack bearing part to prevent the problem of loose stacking caused by the stack of packaging boxes G being directly turned over. The removed pallet T is further processed after being vertically transported downstream, which occupies a small space and has a high equipment utilization rate. A pallet turning mechanism 430 and a pallet stacking mechanism 450 are configured to automatically stack and collect the removed pallets T. The cargo pallet separation and processing equipment of the present embodiment has simple movements throughout the entire process, high stability, and a wide range of applicable products.
