Abstract
Description
Technical Field
[0001] The utility model relates to the field of automatic packaging, in particular to a tray used in an automatic packaging machine, and specifically relates to a wooden tray for automatic packaging and an automatic packaging system. Background Art
[0002] The materials of trays mainly include wood, plastic, metal, etc. Wooden trays are widely used because of their low price, firmness and durability. They can be used as auxiliary equipment for cargo transportation, warehouse cushioning, placing goods (facilitating loading and unloading with forklifts), moisture-proofing, etc. However, the current wooden trays still have the following problems more or less: (1) When multiple wooden trays are stacked and stored, the height is relatively high, which is not conducive to reducing the space occupation ratio; (2) When goods are placed on a wooden tray, it is possible that the placement position is not in the exact middle of the tray and extends out of the tray. Then, when multiple trays need to be placed side by side, after the space is occupied by the goods, the total space is insufficient. If forced to squeeze, it is easy to cause damage and scratches to the part of the goods that extends out of the tray. Therefore, it is only necessary to readjust the placement position of the goods. However, once the goods are heavy, it is very difficult to adjust them manually; (3) Wooden trays are usually processed manually. Limited by the processing level of technicians, the specifications and dimensions of wooden trays are prone to deviation. Since the automatic packaging machine has a high degree of automation and has strict requirements for the specifications and dimensions of trays, otherwise there will be a situation where it cannot be detected and cannot automatically enter the tray warehouse. Therefore, in the industry, a standard plastic tray is added under the wooden tray to facilitate the detection of the wooden tray on the automatic packaging machine and avoid the situation of not being able to enter the tray warehouse due to specification and dimension differences. However, this method cannot solve the fundamental problem, and it increases the labor force, making the fully automatic become semi-automatic. At the same time, the stacked use of wooden trays and plastic trays also increases the stacking height, affecting production convenience and safety, etc. Summary of the Utility Model

[0014] According to some preferred aspects of the utility model, except for the outermost two second make way channels among the n+1 second make way channels, the widths of the other second make way channels along the first direction are greater than or equal to the width of the wooden support member along the first direction.
[0015] In some embodiments, m is less than n.
[0016] In some embodiments, the widths of the m-1 first give way channels along the second direction are all the same.
[0017] According to some preferred aspects of the present utility model, the wooden bearing layer includes a wooden supporting layer and a connecting layer which are arranged in sequence from top to bottom, and the upper surface of the wooden supporting layer forms a bearing surface. The wooden supporting layer is composed of a plurality of wooden supporting members distributed at intervals, and the connecting layer is composed of a plurality of wooden connecting members. The wooden connecting members are used to fix the plurality of wooden supporting members, and the extending direction of the wooden connecting members is perpendicular to the extending direction of the wooden supporting members. The wooden supporting layer is fixedly arranged or detachably arranged on the connecting layer.
[0018] According to some preferred aspects of the present utility model, the wooden supporting member is of a block structure.
[0019] According to some preferred aspects of the present utility model, the wooden pallet for automatic packaging further includes a wooden base layer. The wooden base layer includes n wooden bases respectively extending along the second direction.

DETAILED DESCRIPTION
[0036] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model is described in detail below in conjunction with the accompanying drawings and specific embodiments. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.
[0037] In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise clearly and specifically defined.
[0038] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.
[0039] The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings.
[0040] like Figures 1 to 8As shown, this example provides a wooden pallet for automatic packaging, which includes a wooden bearing layer 1 and a wooden supporting layer 2 arranged in sequence from top to bottom, the orthographic projection of the wooden supporting layer 2 is located in the area of the orthographic projection of the wooden bearing layer 1, and the orthographic projection of the wooden supporting layer 2 and the orthographic projection of the wooden bearing layer 1 have at most two opposite sides overlapping; wherein the wooden bearing layer 1 has a first direction and a second direction perpendicular to each other, and the wooden supporting layer 2 is composed of m×n wooden support members 21 distributed in an array along the first direction and the second direction; in the first direction, the wooden bearing layer 1 and the m wooden support members 21 form m-1 first make way channels 22; in the second direction, the wooden bearing layer 1 and the n wooden support members 21 form n+1 second make way channels 23; the widths of the above-mentioned n+1 second make way channels 23 along the first direction are different.
[0041] In this example, the widths of the n+1 second make way channels 23 along the first direction are larger in the middle and smaller on both sides. Furthermore, n is greater than or equal to 4, and the widths of the n+1 second make way channels 23 along the first direction include a first width L1, a second width L2, and a third width L3, wherein the third width L3 is greater than the first width L1 and less than the second width L2; wherein the widths of the n+1 second make way channels 23 along the first direction are arranged in sequence along the first direction as follows: first width L1, second width L2, third width L3, second width L2, and first width L1. See Figure 1 As shown, a second clearance channel 23 with a smaller width is formed on both sides. The existence of the second clearance channel 23 allows the two pallets to overlap each other, thereby reducing the space occupied in the first direction, and the vertical space is also lower than the height of the two wooden pallets, that is, the overall space occupied can be reduced by overlapping. In this way, when the goods are placed irregularly, the space occupied can be reduced by overlapping, thereby avoiding scratches and damage to the outside world after the goods extend out of the pallet, and there is no need to adjust the placement of the goods, especially for goods with larger volume or weight, it is difficult to adjust their placement manually. Further, in this example, only the two opposite sides of the orthographic projection of the wooden support layer 2 and the orthographic projection of the wooden load-bearing layer 1 are in a coincidence state.
[0042] In this example, except for the two outermost second make way channels 23 among the n+1 second make way channels 23 , the widths of the other second make way channels 23 along the first direction are all greater than or equal to the width of the wooden support member 21 along the first direction.
[0043] In this example, m is smaller than n, and the widths of the m-1 first make way channels 22 along the second direction are all the same.
[0044] In this example, the wooden bearing layer 1 includes a wooden supporting layer 11 and a connecting layer 12, which are arranged in sequence from top to bottom and have a bearing surface formed on the upper surface. The wooden supporting layer 11 is composed of a plurality of wooden supporting members 111 distributed at intervals, and the connecting layer 12 is composed of a plurality of wooden connecting members 121. The wooden connecting members 121 are used to fix the above-mentioned plurality of wooden supporting members 111, and the extension direction of the wooden connecting members 121 is perpendicular to the extension direction of the wooden supporting members 111. The wooden supporting layer 2 is fixedly arranged or detachably arranged on the connecting layer 12.
[0045] Further, see Figure 2 and 3 As shown, the wooden supporting members 111 and the wooden connecting members 121 in this example can both be long wooden blocks. The wooden supporting members 111 can be distributed with multiple wooden blocks at intervals, and the wooden connecting members 121 can also be distributed with multiple wooden blocks at intervals. Among them, the number of wooden supporting members 111 can be greater, and the extension directions are perpendicular to each other; and the function of the wooden connecting members 121 of the lower layer is, on the one hand, to fix the multiple wooden supporting members 111 of the upper layer to maintain stability, and on the other hand, it is also conducive to the arrangement of the wooden support members 21 of the lower layer.
[0046] In this example, the wooden support member 21 is a block structure, for example, a wooden block, further a square wooden block, etc. Figure 4 As shown, in this example, the wooden support members 21 are exemplarily presented in a 3×4 array distribution state, with 4 in the first direction and 3 in the second direction, totaling 12. Of course, in other embodiments, it can also be a 3×5 array distribution, a 4×5 array distribution, etc., which is not specifically limited here.
[0047] In this example, the wooden pallet for automatic packaging also includes a wooden base layer 3, which includes n wooden bases 31 extending along the second direction respectively. The wooden bases 31 are located directly below the wooden support layer 2, and each wooden base 31 supports m wooden support members 21. The setting of the wooden base layer 3 can make the whole more stable and increase the contact area with the placement plane, which is beneficial to structural stability and force dispersion.
[0048] In this example, the wooden pallet for automatic packaging further includes a positioning mechanism, which includes a protrusion provided on the wooden bearing layer 1 and a groove formed on the wooden supporting layer 2, and the protrusion can be inserted into the groove. The setting of the positioning mechanism is conducive to assembling the wooden pallet, and also has an error-proofing effect. The existence of the protrusion and the groove can play an indicating and guiding role. The two must be aligned before the components can be assembled with each other.
[0049] In this example, the wooden pallet for automatic packaging further includes a locking mechanism for mutually locking the wooden bearing layer 1 and the wooden supporting layer 2. Further, the locking mechanism can be a screw, a bolt and a nut, a clamp, etc., as long as the wooden bearing layer 1 and the wooden supporting layer 2 can be mutually locked.
[0050] Further, see Figures 6 to 8 As shown, Figure 6 It shows that two wooden pallets are ready to be stacked in a manner that the bottoms are opposite (i.e. one is inverted relative to the other). It can be seen that the wooden support layer 2 and the wooden base layer 3 can be embedded in the second clearance channel 23, so as to achieve the purpose of reducing the overall vertical space after the two are stacked. Figure 7 The middle is the final state of two wooden pallets already interlocked. Figure 8 It further illustrates the stacking diagram of more wooden pallets. It can be seen that they are stacked on top of each other in pairs and then stacked on top of each other, which greatly reduces the space occupied.
[0051] In some other embodiments, an automatic packaging system is also provided, which includes an automatic packaging machine and a pallet, wherein the pallet includes the above-mentioned wooden pallet for automatic packaging. Further, the automatic packaging machine includes a packaging machine conveying roller 4 and a detection member 5 arranged on one side of the packaging machine conveying roller 4, which can be extended or retracted from the gap between the packaging machine conveying roller 4, and is at least used to detect the presence or absence of the wooden pallet, see Figure 9 As shown, the detection member 5 is tilted and can extend and retract along its own extension direction. When the wooden pallet is driven by the conveying roller 4 of the packaging machine, once the detection member 5 contacts the wooden base 31 of the wooden base layer 3, it means that the existence of the wooden pallet is detected. When the wooden pallet continues to move forward, the wooden base 31 will press the detection member 5 downward to retract it until the wooden pallet completely passes through the detection member 5. In actual operation, when the detection member 5 detects the existence of the wooden pallet, a signal can be given through some auxiliary mechanisms. For example, the conveying roller can be operated to stop moving through a remote control system, and then the goods can be placed on the wooden pallet. After the placement is completed, a signal can be given to make the conveying roller continue to move, so as to realize automatic continuous operation. When the wooden pallet is completely out of contact with the detection member 5, the detection member 5 can return to the initial position, that is, extend to wait for the contact detection position with the next wooden pallet, and so on. The width between the two wooden bases 31 in the middle is the third width L3, which is just enough to ensure that even if the wooden pallet deviates slightly from the middle, the detection member 5 will not fail to detect the wooden pallet, thereby greatly improving the accuracy and convenience.
[0052] In summary, based on the many defects of existing wooden pallets during use, the utility model innovatively provides a wooden pallet for automatic packaging with a new structure. The wooden pallet is improved in structure, specifically including setting the orthographic projection of the wooden support layer to be located within the area of the orthographic projection of the wooden load-bearing layer, so that there is a makeshift space under the wooden load-bearing layer. When multiple pallets are arranged side by side, they can be partially overlapped when necessary to reduce the side-by-side space occupancy. This is conducive to the side-by-side arrangement of multiple pallets when the goods are not arranged regularly, and can also avoid squeezing and scratching the goods. Further, a first makeshift channel and a second makeshift channel are formed in two vertical directions. Such a setting is conducive to stacking multiple pallets in the vertical direction, and having a large part of the interlocking with each other, which greatly reduces the vertical space occupancy. In particular, the utility model makes the widths of the above-mentioned n+1 second makeshift channels along the first direction different, which increases the diversity of choices and is conducive to matching detection pieces of different widths, so that it is easy to be detected when transported on the packaging machine, thereby avoiding the defects caused by the solution of adding plastic pallets using the prior art.
[0053] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
