Description

Technical Field

[0001] This application relates to the field of packaging bottle transfer technology, and more particularly to a nested pallet. Background Technology

[0002] In the pharmaceutical industry, dry heat sterilization of cartridge vials is a crucial step in ensuring drug sterility. The sterilization tray, as the core component for supporting and positioning these vials, directly impacts sterilization efficiency and product quality. Traditional sterilization trays are often made of high-temperature resistant plastic, but they are prone to thermal deformation in continuous high-temperature sterilization environments (e.g., ≥250℃), leading to tray structural instability, vial misalignment, or even tipping, severely affecting sterilization uniformity and subsequent automated production processes. Furthermore, traditional trays have rough surface treatments and insufficient matching precision between mounting holes and vials. During high-speed robotic gripping, friction or stress concentration can easily cause scratches and breakage of the vials, resulting in drug contamination and economic losses. Utility Model Content

[0027] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not 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 this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Figure 1 This is a schematic structural diagram of a nested tray according to one embodiment of the present invention. Figure 1 As shown, and refer to Figures 2 to 5The present application provides a nested pallet, including a stainless steel base plate 100, a sleeve 200 and a support assembly 300. The stainless steel base plate 100 is provided with a mounting hole 110; the sleeve 200 is installed in the mounting hole 110 and extends out of the mounting hole 110; the support assembly 300 is disposed on the stainless steel base plate 100, and the height of the support assembly 300 is greater than the height of the sleeve 200 extending out of the mounting hole 110.

[0031] In this embodiment of the utility model, on the one hand, the base plate is made of stainless steel, which can ensure that the nested tray does not deform under high temperature environment, and at the same time facilitates storage, maintenance and cleaning; on the other hand, since the support component 300 is provided on the stainless steel base plate 100, when the nested trays are stacked, the support component 300 on one nested tray contacts the stainless steel base plate 100 of another nested tray, which plays a stable support role and ensures the stable storage and transportation of the cartridge bottles.

[0032] like Figure 1 , Figure 2 As shown, in one embodiment of this utility model, the nested tray further includes a fixing plate 400, on which a limiting hole 410 coaxial with the mounting hole 110 is provided. The mounting hole 110 is a stepped hole, and a protrusion 210 is provided on the side wall of the sleeve 200; when the sleeve 200 is installed in the mounting hole 110, the bilateral gap between the sleeve 200 and the mounting hole 110 is ≤0.1mm, the protrusion 210 is located between the stepped surface of the stepped hole and the fixing plate 400, and the sleeve 200 passes through the limiting hole 410.

[0033] In this embodiment, the mechanical engagement between the stepped hole structure (mounting hole 110) and the protrusion 210 of the sleeve 200 precisely restricts the sleeve 200 within the axial space between the stepped surface and the fixing plate 400 during installation. This nested structure forms a bidirectional mechanical restraint, preventing both vertical displacement of the sleeve 200 (preventing detachment) and axial movement of the sleeve 200 during transportation vibrations. The limiting hole 410 on the fixing plate 400 is coaxial with the mounting hole 110, forming a double guiding structure. When the sleeve 200 passes through both the stepped hole and the limiting hole 410 simultaneously, it is equivalent to establishing two radial constraint points, significantly improving the sleeve 200's resistance to lateral shear and avoiding the risk of misalignment of the cartridge bottle. In addition, the sleeve 200 and the stainless steel base plate 100 are fitted together by the stepped installation structure of the sleeve 200, with a bilateral gap of ≤0.1mm, and are locked to the stainless steel base plate 100 by screws through the fixing plate 400, ensuring that the deformation rate is ≤0.1mm after more than 120 high-temperature sterilization cycles.

[0034] Specifically, the stainless steel base plate 100, support assembly 300, fixing plate 400, and sleeve 200 are all made of 304 stainless steel, which can withstand temperatures above 300℃ and has both deformation resistance and corrosion resistance. The stainless steel base plate 100 is treated with quenching and precision grinding processes, and its flatness is ≤0.1mm, completely solving the problem of insufficient flatness caused by traditional processing methods. Multiple sleeves 200 have the same outer diameter, but their inner diameters may be the same or different.

[0035] like Figure 3 As shown, in one embodiment of this utility model, there are multiple mounting holes 110; the mounting holes 110 are arranged in an array along the length and width directions of the stainless steel base plate 100; the limiting holes 410 are provided in a one-to-one correspondence with the mounting holes 110. Specifically, in the length direction of the stainless steel base plate 100, the mounting holes 110 are distributed in 24 rows at intervals; in the width direction of the stainless steel base plate 100, the mounting holes 110 are distributed in 10 rows at intervals. Each nested tray can hold 240 cartridge bottles, adapting to standardized sterilization processes and meeting the load-bearing requirements of cartridge bottle drying ovens.

[0036] Furthermore, the stainless steel base plate 100 is provided with a plurality of first process holes 120, which are located on one or both sides of any row of mounting holes 110; the fixing plate 400 is provided with a plurality of second process holes 420, each second process hole 420 communicating with one first process hole 120. The provision of the first process holes 120 and the second process holes 420 can be used to reduce weight and reduce the heat required for heating, thereby achieving the purpose of energy saving.

[0037] like Figure 4 , Figure 5 As shown, in one embodiment of this utility model, the support assembly 300 includes a support column 310, which is detachably mounted on a stainless steel base plate 100. The height of the support column 310 is greater than the length of the sleeve 200 extending out of the mounting hole 110. The support column 310 and the sleeve 200 are located on the same side of the stainless steel base plate 100. A through hole 430 is provided on the fixing plate 400, through which the support column 310 passes. The height of the support column 310 is 20.00 mm to 35.00 mm, and the outer diameter tolerance of the support column 310 is controlled within ±0.05 mm to ensure installation accuracy. When multiple nested trays are stacked, the support column 310 in the lower nested tray abuts against the stainless steel base plate 100 of the upper nested tray, so that the sleeve 200 is not under pressure. The multiple support columns 310 are evenly distributed on the stainless steel base plate 100 to ensure the vertical positioning accuracy of the cartridge bottles and prevent the nested trays from tipping over or colliding.

[0038] In one embodiment of this utility model, the support component 300 includes a frame 320, which is disposed at both ends of the stainless steel base plate 100. The frame 320 and the sleeve 200 are located on the same side of the stainless steel base plate 100; or, the frame 320 and the sleeve 200 are located on opposite sides of the stainless steel base plate 100. The frame 320 facilitates the stacking, storage, and retrieval of the nested pallets. Furthermore, a positioning hole is provided at the end of the frame 320 away from the stainless steel base plate 100; a positioning pin coaxial with the positioning hole is detachably provided on the side of the stainless steel base plate 100 opposite to the frame 320; when multiple nested pallets are stacked, the positioning pin on one stainless steel base plate 100 is inserted into the positioning hole of the frame 320 on the upper side of another stainless steel base plate 100, which serves as a coarse positioning function.

[0039] When the frame 320 and sleeve 200 are located on the same side of the stainless steel base plate 100, and multiple nested pallets are stacked, the frame 320 of the lower nested pallet abuts against the stainless steel base plate 100 of the upper nested pallet, so that the sleeve 200 is not under pressure. When the frame 320 and sleeve 200 are located on opposite sides of the stainless steel base plate 100, and multiple nested pallets are stacked, the frame 320 of the upper nested pallet abuts against the stainless steel base plate 100 of the lower nested pallet, and the sleeve 200 of the lower nested pallet is located between the two stainless steel base plates 100, so that the sleeve 200 is not under pressure.

[0040] In one embodiment of this utility model, there are multiple fixing plates 400, which are spaced apart along the length of the stainless steel base plate 100, which can reduce the stress concentration caused by thermal expansion and contraction of the fixing plates 400.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model, and should all be included within the protection scope of this utility model.
