Description

Technical Field

[0001] This invention relates to the field of racking technology, and more specifically to a logistics rack that facilitates palletizing. Background Technology

[0002] With the development of the logistics industry, the warehousing of logistics goods has become particularly important. Logistics racks are usually set up to stack and place goods. Traditional racks are mainly fixed multi-layer shelf structures, on which goods are stacked.

[0003] In addition, there are some palletizing racks in related technologies. These racks are mainly composed of several individual racks stacked from bottom to top, meaning that each individual rack can be used as a carrier for placing goods. Compared with traditional fixed racks, the advantage of this type of rack is that each individual rack can be used as a carrier for stacking goods and can also be used directly as a pallet. After the goods are placed on the individual rack, a forklift can be used to lift the individual racks for stacking.

[0004] For existing stacking racks, the top four corners of each individual rack are usually equipped with insertion holes, and the bottom four corners are equipped with corresponding insertion posts. During stacking, the insertion posts at the bottom of the upper individual rack are inserted into the insertion holes at the top of the lower individual rack to achieve stacking. Therefore, it is generally referred to as four-corner stacking or four-corner positioning in the industry. With the positioning of the insertion holes and insertion posts, the upper individual rack can be prevented from slipping off the lower individual rack, thus ensuring that the stacked rack is relatively stable.

[0005] However, the existing stacking racks still have shortcomings in practical use. Generally speaking, when stacking individual racks, these racks mainly rely on a forklift to lift the individual rack to be stacked and lift it above the lower individual rack. Then, the forklift driver operates the forklift to align the bottom post of the lifted individual rack with the top hole of the bottom individual rack. Then, the forklift driver lowers the individual rack until the two individual racks are stacked.

[0006] Therefore, it is evident that during this process, the forklift operator needs to accurately align the pins and posts of the individual frames on both the upper and lower levels. For stacking two to three individual frames, the operator can generally stack them normally. However, as the number of stacked individual frames increases, the stacking height also increases accordingly. As a result, when continuing to stack, the forklift operator will find it difficult to see whether the pins and posts of the next stacked individual frame are vertically aligned with the top individual frame, which will greatly increase the difficulty of operating the forklift. Moreover, the lifting height of the forklift is limited, making it difficult to stack higher-level individual frames. Summary of the Invention

[0007] In order to solve at least one of the technical problems mentioned in the background art, the object of the present invention is to provide a logistics placement rack that facilitates palletizing.

[0008] To achieve the above objectives, the present invention provides the following technical solution:

[0009] A palletizing logistics storage rack includes:

[0010] At least two individual racks are provided, which can be stacked vertically in sequence in the stacking area. The top of each individual rack is provided with an insertion hole and the bottom of each rack is provided with a post corresponding to the insertion hole.

[0011] A support frame, used to lift individual frames;

[0012] Positioning components are used to position the individual frame on the carrier in the horizontal direction;

[0013] Vertical drive mechanism, used to drive the vertical movement of the carrier frame;

[0014] A lateral drive mechanism is used to drive the carrier to move laterally between an initial position and an end position. In the initial position, the carrier is located on the side of the stacking area. When the carrier carries the individual frame to the end position, the individual frame on the carrier is located in the stacking area, and the insertion post of the individual frame on the carrier is vertically aligned with the insertion hole of the top individual frame in the stacking area.

[0015] The advantages of using this solution are:

[0016] This solution uses a carrier, positioning components, and vertical and horizontal drive mechanisms to enable the use of forklifts to stack the bottom individual frames (such as the bottom 2 or 3 layers of individual frames) to form a basic frame group when stacking individual frames.

[0017] When it is necessary to continue stacking on top of the base frame, a forklift can be used to lift the individual frame to be stacked (for simplicity, this individual frame is referred to as the high-level individual frame). Then, it is placed on the carrier arm and positioned by the positioning component. In this way, the high-level individual frame will not move horizontally on the carrier. Then, the high-level individual frame is lifted above the base frame by the vertical drive mechanism. Then, the high-level individual frame is moved laterally to the end position by the horizontal drive mechanism. At this time, the insertion post at the bottom of the high-level individual frame is directly above the insertion hole on the top individual frame of the base frame. Then, the high-level individual frame is lowered by the vertical drive mechanism. During the lowering process, the insertion hole and the insertion post gradually engage. Finally, the high-level individual frame is placed on the top individual frame. Finally, the control arm is reset to complete the stacking.

[0018] Therefore, it can be seen that the placement rack provided by this solution can facilitate forklift drivers to perform stacking operations. This is because the stacking of the basic rack group is generally a stacking of 2 to 3 individual racks, and the height is not very high. It is still within the normal line of sight of the driver, and the driver can operate the forklift normally to align the sockets and posts when stacking.

[0019] When continuing to stack at higher levels, the driver does not directly stack the high-level individual frames on the base frame assembly. The driver only needs to use the forklift to place the high-level individual frames onto the carrier arm, which will then continue to stack them. The carrier arm can be driven to a lower position via a vertical drive mechanism, at which point the driver can properly place the high-level individual frames onto the carrier frame.

[0020] In summary, when stacking individual racks, the driver operates the forklift at a relatively low height, avoiding the problem of obstructed vision and difficulty in aligning the insertion holes and posts due to a higher operating height, which would affect the stacking operation.

[0021] In addition, this solution, through the cooperation of vertical drive mechanism, horizontal drive mechanism and carrier, can realize the combination of multiple layers of single frames without being limited by the lifting height of the forklift.

[0022] Preferably, the stacking area includes positioning holes that correspond one-to-one with the insertion posts at the bottom of the individual frame for insertion of the insertion posts. When the insertion post is inserted into the positioning hole, the individual frame is positioned in the stacking area in the horizontal direction.

[0023] Preferably, the positioning component includes a positioning hole and a positioning post that can be vertically inserted, wherein one of the positioning hole and the positioning post is located on the carrier arm and the other is located on the single frame.

[0024] Preferably, the positioning hole is opened on the carrier arm, and the positioning post is set on the single frame, wherein the positioning post is a structure that can be elastically extended and retracted vertically, and in its natural state, the positioning post is in the extended state.

[0025] Preferably, the single frame is provided with an elastic component, which includes a fixed sleeve fixed on the single frame and a spring disposed in the fixed sleeve. The positioning post is vertically movably inserted through the fixed sleeve. The spring is sleeved on the positioning post, with its upper end abutting against the top wall of the fixed sleeve and its lower end abutting against the positioning post. In its natural state, the positioning post is pushed to remain extended under the elastic force of the spring.

[0026] Preferably, the top of the fixing sleeve has a through hole for the positioning post to extend vertically, and the peripheral wall of the positioning post has an indicator mark. In its natural state, the indicator mark is located inside the fixing sleeve, and when the positioning post is lifted upward a certain distance, the indicator mark is exposed outside the fixing sleeve.

[0027] Preferably, the vertical drive mechanism includes a frame and a lead screw linear module mounted on the frame, and the carrier arm is fixed to the lead screw linear module and driven to move vertically by the lead screw linear module.

[0028] Preferably, the lateral drive mechanism includes a laterally extending track and a hydraulic cylinder. The upright is slidably mounted on the track, and the hydraulic cylinder is fixedly mounted on the track and fixed to the upright to drive the upright to move laterally.

[0029] Preferably, the stacking area includes positioning holes that correspond one-to-one with the insertion posts at the bottom of the individual frame for insertion of the insertion posts. When the insertion post is inserted into the positioning hole, the individual frame is positioned in the stacking area in the horizontal direction, and the positioning holes are located on the track.

[0030] Preferably, the carrier frame is a U-shaped structure, which includes two carrier arms parallel to the transverse direction; each side of the single frame is provided with a support part corresponding to the position of the two carrier arms, and the support part is used to support the carrier arms.

[0031] Other advantages and effects of the present invention will be specifically explained in the detailed description and accompanying drawings. Attached Figure Description

[0038] The technical solutions of the embodiments of the present invention will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present invention and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present invention.

[0039] In the following description, terms such as “inner,” “outer,” “upper,” “lower,” “left,” and “right” that indicate orientation or positional relationship are used only for the convenience of describing the embodiments and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0040] Please see Figure 1-6 As shown, this embodiment provides a logistics placement rack that facilitates palletizing, including several individual racks 1, carrier racks 2, positioning components, vertical drive mechanisms, and horizontal drive mechanisms. The following is a detailed description of each component.

[0041] like Figure 1 As shown, each individual rack 1 includes at least two layers, and each individual rack 1 can be stacked vertically in the stacking area. For example, in this embodiment, for ease of demonstration, a three-layer individual rack 1 is shown.

[0042] The single-unit frame 1 has an insertion hole 121 at the top and an insertion post 13 at the bottom corresponding to the insertion hole 121. Specifically, in this embodiment, a quadrilateral single-unit frame 1 is used as an example. It mainly includes a base plate 11 and four uprights 12 located at the four corners of the base plate 11. Goods are placed on the base plate 11. An insertion hole 121 is opened at the top of each upright. Four insertion posts 13 are located at the four corners of the bottom of the base plate 11, directly below the uprights 12. The insertion posts 13 and the insertion holes 121 are vertically aligned. When stacking, the insertion posts 13 on the upper single-unit frame 1 are vertically inserted into the insertion holes 121 on the lower single-unit frame 1 to realize the stacking between the two single-unit frames 1.

[0043] Carrier 2 is used to support the single frame 1; such as Figure 4 As shown, the carrier 2 is preferably a U-shaped structure, which includes two carrier arms 21 parallel to the transverse direction; as Figure 1 As shown, each side of the single frame 1 is provided with a support part 111 corresponding to the position of the two carrier arms 21. The support part 111 is used to support the carrier arms 21. Specifically, at least one set of opposite sides of the base plate 11 extends outward to form an extension part, which constitutes the support part 111. In use, the two support parts 111 are respectively mounted on the two carrier arms 21.

[0044] In addition, to facilitate forklift lifting of the single frame 1, in this embodiment, as follows: Figure 1 As shown, two L-shaped support arms 14 are fixed to the top of the side of the base plate 11 adjacent to the two support parts 111. The two support arms 14 are used for the two forks of the forklift to insert.

[0045] The positioning component is used to position the individual frame 1 on the carrier 2 in the horizontal direction, that is, under the positioning of the positioning component, the individual frame 1 placed on the carrier 2 cannot be offset relative to the carrier 2 in the horizontal direction.

[0046] A vertical drive mechanism is used to drive the carrier 2 to move vertically;

[0047] The lateral drive mechanism is used to drive the carrier 2 to move laterally between the initial position and the final position. The initial position can be referenced... Figure 1 As shown, the carrier 2 is located to the side of the palletizing area; when the carrier 2 carrying the single frame 1 travels to the end position, it can be referred to Figure 2 As shown, the individual frame 1 on the carrier 2 is located in the stacking area, and the insertion post 13 of the individual frame 1 on the carrier 2 is vertically aligned with the insertion hole 121 of the individual frame 1 located at the top layer of the stacking area.

[0048] Therefore, when stacking individual racks 1, a forklift can be used to directly stack the bottom individual racks 1 (such as the bottom 2nd or 3rd layer individual racks 1) to form a basic rack group, where the basic rack group can be referred to Figure 1 As shown in section B, in other words, the stacking of the basic rack group is mainly carried out directly by forklifts; as for the specific number of individual racks 1 that make up the basic rack group, it depends on the height of the individual racks 1. For example, if the individual racks 1 are relatively short, more individual racks 1 can be used to make up the basic rack group. Conversely, if the individual racks 1 are relatively tall, they can be made up of one or a few individual racks 1. For example, this embodiment specifically shows the case where two individual racks 1 make up the basic rack group.

[0049] When it is necessary to continue stacking the base frame assembly, a forklift can be used to lift the individual frame 1 to be stacked (for simplicity, this individual frame 1 will be referred to as the high-level individual frame 1). The high-level individual frame 1 can be referred to as... Figure 1 As shown in section A.

[0050] It is then placed on the carrier arm 21 and positioned by the positioning component, so that the high-level single frame 1 will not move horizontally on the carrier 2.

[0051] Next, the high-level single frame 1 is lifted above the base frame group by the vertical drive mechanism, and then the high-level single frame 1 is driven to move laterally to the end position by the horizontal drive mechanism. At this time, the insertion post 13 at the bottom of the high-level single frame 1 is directly above the insertion hole 121 on the top single frame 1 of the base frame group.

[0052] Next, the high-level single unit frame 1 is lowered using the vertical drive mechanism. During the lowering process, the insertion hole 121 and the insertion post 13 are gradually inserted, and finally the high-level single unit frame 1 sits on the top single unit frame 1. Finally, the control arm is reset to achieve stacking.

[0053] Therefore, the placement rack provided by this solution can facilitate forklift drivers to perform stacking operations. This is because the basic rack group is generally a stacking of 2 to 3 layers of individual rack 1, and the height is not very high. It is still within the driver's normal line of sight, and the driver can operate the forklift normally to align the insertion holes 121 and insertion posts 13 when stacking.

[0054] When continuing to stack at higher levels, the driver does not directly stack the high-level single unit frame 1 on the base frame group. The driver only needs to use the forklift to place the high-level single unit frame 1 onto the carrier arm 21, and then the carrier arm 21 will continue to stack it. The carrier arm 21 can be driven to a lower position by the vertical drive mechanism. At this lower position, the driver can normally place the high-level single unit frame 1 onto the carrier 2.

[0055] In summary, when stacking individual frames 1, the driver operates the forklift at a relatively low height, thus avoiding the problem of obstructed vision due to a higher operating height, which would hinder the alignment of the insertion holes 121 and the insertion posts 13 and affect the stacking operation.

[0056] In addition, through the cooperation of the vertical drive mechanism, the horizontal drive mechanism, and the carrier 2, this solution can achieve the combination of multiple layers of single frames 1 without being limited by the lifting height of the forklift.

[0057] Finally, it is worth noting that the reason why this solution can utilize the vertical drive mechanism, the horizontal drive mechanism, and the carrier 2 to continue stacking the high-level single-unit rack 1 lies in the positioning problem, mainly three positioning issues: First, after the forklift places the high-level single-unit rack 1 on the carrier 2, the high-level single-unit rack 1 cannot move laterally relative to the carrier 2 in the horizontal direction; second, when the carrier 2 brings the single high-level rack above the base rack group, the insertion post 13 at the bottom of the high-level single-unit rack 1 must be directly above the insertion hole 121 of the top single-unit rack 1 in the base rack group; third, the positioning problem of the bottom single-unit rack 1, which must be ensured that the bottom single-unit rack 1 is positioned in the predetermined position (i.e., the aforementioned stacking area) from the beginning, and cannot move in the horizontal direction.

[0058] The first positioning problem mentioned above is mainly solved by the positioning component, which ensures that the high-position single frame 1 will not undergo relative horizontal displacement on the carrier 2. This is because once relative horizontal displacement occurs, even if the carrier 2 subsequently travels to the end position, the insertion hole 121 and the insertion post 13 will be misaligned and unable to be inserted into each other.

[0059] As for the second positioning problem, it is mainly achieved by the driving stroke of the lateral drive mechanism. That is, the end position of the stroke of the lateral drive mechanism can be preset. Of course, a proximity switch can also be set to control the end position. For example, a proximity switch can be set at the end position. When the lateral drive mechanism drives the carrier 2 to the end position, the proximity switch is triggered, and the lateral drive mechanism stops moving forward in response to the proximity switch.

[0060] Regarding the third positioning problem, since subsequent stacking is based on the bottommost single-unit rack 1, if the bottommost single-unit rack 1 is misaligned, even if the previous two positioning problems are solved, it will be impossible to accurately stack the subsequent higher-level single-unit racks 1; because the endpoint position depends on the position of the bottommost single-unit rack 1, and these two positions must be corresponding.

[0061] The third positioning problem is mainly solved by setting up a palletizing area, which positions the individual frame 1 within the palletizing area. For example, limiting holes 631 are fixedly set in the palletizing area, corresponding one-to-one with the insertion posts 13 at the bottom of the individual frame 1 for insertion of the insertion posts 13. When the insertion post 13 is inserted into the positioning hole 211, the individual frame 1 is positioned horizontally within the palletizing area, thus preventing horizontal displacement.

[0062] In this embodiment, the positioning component is specifically configured as follows:

[0063] Combination Figure 1 and Figure 5 As shown, the positioning assembly includes a positioning hole 211 and a positioning post 3 capable of vertical insertion. One of the positioning hole 211 and the positioning post 3 is located on the carrier arm 21, and the other is located on the single frame 1. Specifically, in this embodiment, as... Figure 4 As shown, two positioning holes 211 are provided and opened on the same carrier arm 21, and two positioning posts 3 are correspondingly provided and set on the support part 111 of the single frame 1. The two positioning holes 211 and the two positioning posts 3 correspond one-to-one.

[0064] In use, the forklift lifts the elevated single-unit frame 1 and moves it above the boom 21. Then, the forklift is operated to align the positioning hole 211 with the positioning post 3. Finally, the elevated single-unit frame 1 is lowered using the forklift. Figure 5 The state shown.

[0065] During the process of lowering the high-level single frame 1 to the carrier arm 21, if the positioning post 3 and the positioning hole 211 are not aligned and misalignment occurs, such as... Figure 6As shown in the diagram, as the high-level single frame 1 is lowered, the positioning column 3 will directly contact the carrier arm 21 and will not be able to penetrate the positioning hole 211. As a result, the positioning column 3 will lift up the high-level single frame 1. Since there is no positioning column 3 on the other side of the high-level single frame 1, the high-level single frame 1 will tilt, which will easily lead to the danger of the single frame 1 tipping over.

[0066] To address this issue, in this embodiment, the positioning post 3 is configured as a structure capable of elastic expansion and contraction along the vertical direction. In its natural state, as... Figure 5 As shown, the positioning post 3 is in the extended state. Because the positioning post 3 is an elastically expandable structure, if the positioning post 3 and the positioning hole 211 are not aligned, such as... Figure 6 As shown, during the lowering process of the high-position positioning frame, the positioning column 3 directly contacts the carrier arm 21. As it continues to be lowered, the positioning column 3 can overcome the elasticity and continuously retract inward, so that the high-position single frame 1 will not tilt due to the positioning column 3 lifting it.

[0067] Specifically, such as Figure 5 As shown, the single frame 1 is provided with an elastic member, which includes a fixing sleeve 41 fixed on the single frame 1 and a spring 42 provided in the fixing sleeve 41. Preferably, the fixing sleeve 41 is vertically fixed on the upper surface of the support part 111.

[0068] The positioning post 3 is vertically movably inserted through the fixed sleeve 41; the spring 42 is sleeved on the positioning post 3, with its upper end abutting against the top wall of the fixed sleeve 41 and its lower end abutting against the positioning post 3. In its natural state, the positioning post 3 is pushed to remain extended under the elastic force of the spring 42.

[0069] To allow the driver to visually determine whether the positioning post 3 is inserted into the positioning hole 211 when the high-mounted single frame 1 is lowered onto the boom 21, in this embodiment, the top of the fixing sleeve has a through hole for the positioning post 3 to extend vertically, and the peripheral wall of the positioning post 3 has an indicator mark 31. In its natural state, as... Figure 5 As shown, the indicator mark 31 is located inside the fixed sleeve. When the positioning post 3 is lifted upwards a certain distance (for example, when the lower end of the positioning post 3 is flush with the lower wall of the base plate 11, it can be referenced...), Figure 6 (as shown in the diagram), the indicator mark 31 is exposed outside the fixing sleeve.

[0070] Thus, the driver can determine whether the positioning pin 3 has been inserted into the positioning hole 211 simply by observing whether the indicator mark 31 appears. If the indicator mark 31 appears, it indicates that the positioning pin 3 is in the retracted state and has not been inserted into the positioning hole 211; otherwise, it indicates that it has been inserted into the positioning hole 211.

[0071] The indicator mark 31 can be a colored coating, such as a red coating, applied to the outer periphery of the positioning post 3.

[0072] In this embodiment, the specific structures of the vertical drive mechanism and the horizontal drive mechanism are as follows:

[0073] like Figure 4 As shown, the vertical drive mechanism includes a frame 51 and a lead screw linear module mounted on the frame 51. The carrier arm 21 is fixed on the lead screw linear module and is driven to move vertically by the lead screw linear module.

[0074] The linear module of lead screw 52 mainly includes lead screw 52, ​​motor (not shown in the figure), and guide rod 53. Lead screw 52 is vertically arranged and rotatably connected to the upright frame 51; guide rod 53 is vertically fixed to the upright frame 51; motor is installed on the top of the upright frame 51 to drive lead screw 52 to rotate. The carrier frame 2 is vertically movably inserted through the guide rod 53. Lead screw 52 is threadedly connected to carrier frame 2. Thus, the rotation of lead screw 52 can drive carrier frame 2 to move vertically.

[0075] The lateral drive mechanism includes a laterally extending track 61 and a hydraulic cylinder 62, wherein there are two tracks 61, and the tracks 61 can be fixed to the ground by means of screws or the like.

[0076] The lower end of the upright frame 51 is slidably mounted on the track 61. The hydraulic cylinder 62 is fixedly mounted on the track 61 and fixed to the upright frame 51 to drive the upright frame 51 to move laterally. That is, the upright frame 51 is driven to move laterally on the track 61 by the action of the hydraulic cylinder 62. In this way, the carrier 2 on the upright frame 51 moves laterally together with the upright frame 51, so as to achieve the purpose of the lateral drive mechanism driving the carrier 2 to move laterally.

[0077] like Figure 4 As shown, the limiting hole 631 can be set on the track 61. For example, four legs 63 can be fixedly set on the track 61, and the limiting hole 631 can be opened on the top of the four legs 63.

[0078] Furthermore, it is worth noting that in this embodiment, the lateral movement of the support frame 51 is achieved by using a lateral drive mechanism to drive the lateral movement of the support frame 2. The significance of this is that, after stacking is completed, the hydraulic cylinder 62 can push the entire support frame 51 to partially close at the position of the stacked individual frame 1 (see reference). Figure 3 As shown in the diagram, after the stacking is completed, the uprights 51 are joined together at the position of the individual frame 1, thereby reducing the overall footprint of the uprights 51 and the individual frame 1 to facilitate pedestrian passage.

[0079] Furthermore, after completing the topmost single frame 1, it is preferable to... Figure 3In the state shown, the carrier 2 is not controlled to reset, but the insertion hole 121 on the carrier arm 21 is kept in the insertion state with the positioning post 3 of the uppermost single frame 1. At this time, the carrier 2 is equivalent to being placed together with the single frame 1 after stacking, and the carrier 2 is equivalent to surrounding the upper single frame 1. In this way, the insertion state of the insertion hole 121 and the positioning post 3 of the uppermost single frame 1 allows the carrier 2 to play a certain role in stabilizing the entire assembled single frame 1 and reducing the risk of the assembled single frame 1 tipping over.

[0080] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within the present invention.
