Description

Technical Field

[0001] This application relates to the field of material conveying, and more particularly to a guardrail passage switching component and conveying device. Background Technology

[0002] In the field of freeze-dried formulation production, existing production processes typically include key steps such as bottle washing, drying, filling, and freeze-drying. In conventional production line configurations, filled vials are transferred to the freeze-drying machine's trays via an automated feeding and discharging system for freeze-drying. After the freeze-drying process, they are then transferred to the capping station for sealing. With increasing capacity demands, modern production workshops generally adopt a parallel layout of multiple freeze dryers, commonly in T- or Y-shaped configurations, where two or more freeze dryers are symmetrically positioned on either side of the filling machine's extension conveyor line.

[0003] However, after completing the continuous feeding operation of one freeze dryer, the guide rails of the conveyor line must be physically disassembled and reinstalled before switching to the feeding operation of the other freeze dryer. This railing replacement process not only consumes a lot of manual operation time, but also causes frequent interruptions in the production line, seriously affecting production efficiency. Utility Model Content

[0004] This application provides a guardrail channel switching component and conveying device, which aims to improve the production efficiency problem caused by the guardrail replacement process.

The third guardrail is at least partially disposed between the first guardrail and the second guardrail and is located at the end away from the bottle inlet channel. The first guardrail, the second guardrail, and the third guardrail together form the mounting hole. A bottle outlet channel is formed between the third guardrail and each of the first and second guardrails.

[0011] Optionally, the base guardrail also includes a plurality of first connectors, and the first guardrail and the second guardrail, the first guardrail and the third guardrail, and the third guardrail and the second guardrail are all detachably connected by the first connectors.

[0012] Optionally, the base guardrail further includes a connecting plate, which is disposed at the bottom of the base guardrail and extends to the bottom of the mounting hole. The turntable guardrail is rotatably disposed on the connecting plate.

This improves the time for switching bottle outlet channels and thus increases production efficiency. Furthermore, it effectively avoids the risk of particulate contamination caused by traditional disassembly and assembly methods. Attached Figure Description

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 guardrail passage switching component provided in one embodiment of this utility model. Figure 1 As shown, and refer to Figures 2 to 6This application provides a guardrail channel switching component, including a bottle inlet channel 100, multiple bottle outlet channels 300, and a switching channel 200; the bottle inlet channel 100 and the multiple bottle outlet channels 300 are spaced apart; the switching channel 200 is rotatably disposed between the bottle inlet channel 100 and the bottle outlet channels 300; the switching channel 200 is configured as follows:

[0031] When it rotates to the first position, the bottle inlet channel 100 is connected to one of the bottle outlet channels 300, and the remaining bottle outlet channels 300 are blocked;

[0032] When it rotates to the second position, the bottle inlet channel 100 is connected to another bottle outlet channel 300, and the remaining bottle outlet channels 300 are blocked.

[0033] In this embodiment of the invention, a conversion channel 200 is provided between the bottle inlet channel 100 and multiple bottle outlet channels 300, connecting one of the multiple bottle outlet channels 300 to the bottle inlet channel 100. When the conversion channel 200 rotates to the first station, it forms a continuous guiding channel with the target bottle outlet channel 300, while physically isolating non-target bottle outlet channels 300, ensuring unidirectional and accurate material flow. When switching to the second station, the path connection to the new target bottle outlet channel 300 and the blocking of non-associated bottle outlet channels 300 are simultaneously completed by adjusting the axial rotation angle, completely eliminating the manual disassembly and assembly of guardrails when the freeze dryer is used alternately in the traditional layout, improving the time for switching bottle outlet channels 300, and thus improving production efficiency. In addition, it effectively avoids the risk of particulate contamination caused by the traditional disassembly and assembly mode.

[0034] Specifically, such as Figure 1 , Figure 2 As shown, to achieve the above functions, the guardrail channel switching component further includes a base guardrail 400 and a turntable guardrail 500. The base guardrail 400 is provided with a mounting hole 440. The bottle inlet channel 100 and the bottle outlet channel 300 are both provided on the base guardrail 400 and communicate with the mounting hole 440. The turntable guardrail 500 is rotatably disposed in the mounting hole 440, and the switching channel 200 is disposed on the turntable guardrail 500.

[0035] Furthermore, there are two bottle outlet channels 300, which are spaced apart from each other; the conversion channel 200 includes a first sub-channel 210 and a second sub-channel 220, the first sub-channel 210 is used to connect the bottle inlet channel 100 to one of the bottle outlet channels 300, and the second sub-channel 220 is used to connect the bottle inlet channel 100 to the other bottle outlet channel 300.

[0036] In this embodiment, the independently distributed bottle outlet channels 300 can correspond to the freeze dryers on both sides of the T / Y type layout. Combined with the directional connection function of the first sub-channel 210 and the second sub-channel 220, a physically isolated dual material flow path is formed. When it is necessary to switch the conveying direction, the path conversion can be completed simply by directional switching of the sub-channels (i.e., the first sub-channel 210 and the second sub-channel 220), completely eliminating the manual disassembly and assembly of guardrails when alternating freeze dryers in traditional layouts, achieving zero-downtime switching.

[0037] In one embodiment of this utility model, the base guardrail 400 includes a first guardrail 410, a second guardrail 420, and a third guardrail 430. The first guardrail 410 and the second guardrail 420 are spaced apart in the horizontal direction to form the bottle inlet channel 100 between the two at one end of the first guardrail 410 and the second guardrail 420. The third guardrail 430 is at least partially disposed between the first guardrail 410 and the second guardrail 420 and is located at one end away from the bottle inlet channel 100. The first guardrail 410, the second guardrail 420, and the third guardrail 430 enclose the mounting hole 440. A bottle outlet channel 300 is formed between the third guardrail 430 and each of the first guardrail 410 and the second guardrail 420. Accordingly, the turntable guardrail 500 includes a fourth guardrail 510, a fifth guardrail 520, and a sixth guardrail 530. The fourth guardrail 510 and the sixth guardrail 530 are spaced apart in the horizontal direction, and the fifth guardrail 520 is disposed between the fourth guardrail 510 and the sixth guardrail 530. A first sub-channel 210 is formed between the fourth guardrail 510 and the fifth guardrail 520, and a second sub-channel 220 is formed between the fifth guardrail 520 and the sixth guardrail 530.

[0038] Furthermore, the base guardrail 400 also includes multiple first connectors 450. The first guardrail 410 and the second guardrail 420, the first guardrail 410 and the third guardrail 430, and the third guardrail 430 and the second guardrail 420 are all detachably connected via the first connectors 450. The multiple first connectors 450 connect the first guardrail 410, the second guardrail 420, and the third guardrail 430 into a single unit, fixing the position, shape, and size of the bottle inlet channel 100, the mounting hole 440, and the bottle outlet channel 300. This ensures stable operation of the guardrail channel switching assembly and avoids impacting production efficiency. Similarly, the turntable guardrail 500 also includes a plurality of second connectors 550, each of which is connected to the fourth guardrail 510, the fifth guardrail 520, and the sixth guardrail 530, thereby connecting the fourth guardrail 510, the fifth guardrail 520, and the sixth guardrail 530 into a whole, so that the shape and size of the turntable guardrail 500 are fixed and the movement interference between the turntable guardrail 500 and the base guardrail 400 is avoided.

[0039] like Figure 3 As shown, in one embodiment of this utility model, the base guardrail 400 further includes a connecting plate 460, which is connected to the lower end of the third guardrail 430. The connecting plate 460 extends to the bottom of the mounting hole 440, and the turntable guardrail 500 is rotatably mounted on the connecting plate 460. Specifically, the bottom of the third guardrail 430 near the mounting hole 440 is provided with a mounting groove, which communicates with the mounting hole 440. The connecting plate 460 has a fan-shaped structure, with its arc end set in the mounting groove and its tip extending into the mounting hole 440, located at the bottom of the mounting hole 440. The bottom of the turntable guardrail 500 is provided with a fan-shaped limiting groove 560. When the turntable guardrail 500 is installed in the mounting hole 440, the connecting plate 460 is located in the limiting groove 560, and the turntable guardrail 500 and the connecting plate 460 are rotatably connected. The central angle of the limiting groove 560 is larger than that of the connecting plate 460, and it is configured such that: when the connecting plate 460 contacts one side wall of the limiting groove 560, the conversion channel 200 on the turntable guardrail 500 is located at the first station; when the connecting plate 460 contacts the other side wall of the limiting groove 560, the conversion channel 200 is located at the second station. In other words, when the turntable guardrail 500 rotates, the connecting plate 460 is always located within the limiting groove 560; the cooperation between the connecting plate 460 and the limiting groove 560 restricts the rotation angle of the turntable guardrail 500, and the conversion channel 200 only connects to the target bottle outlet channel 300 when the connecting plate 460 contacts the wall of the limiting groove 560, ensuring accurate channel positioning.

[0040] Furthermore, such as Figure 4As shown, the tip of the connecting plate 460 has a first through hole. A bolt passes through the first through hole from the bottom of the connecting plate 460 and is screwed onto the nut 810. A bearing 820 is sleeved on the bolt, and the bearing 820 is located between the connecting plate 460 and the nut 810. The fifth guardrail plate 520 has a second through hole, and the bearing 820 is embedded in the second through hole so that the fifth guardrail plate 520 can rotate through the bearing 820.

[0041] In one embodiment of this utility model, the base guardrail 400 further includes a first diverting strip 470 and a plurality of second diverting strips 480. The first diverting strip 470 is disposed within the bottle inlet channel 100 to divide the bottle inlet channel 100 into two flow channels. Each second diverting strip 480 is disposed within a bottle outlet channel 300 to divide the bottle outlet channel 300 into two flow channels. The two flow channels of each bottle outlet channel 300 correspond to the two flow channels of the bottle inlet channel 100. Each first diverting strip 470 / second diverting strip 480 is connected to a first connecting member 450, thereby connecting the first diverting strip 470, the second diverting strip 480, the first guardrail 410, the second guardrail 420, and the third guardrail 430 into a whole. Correspondingly, the turntable guardrail 500 also includes two third diversion strips 540. One third diversion strip 540 is disposed within the first sub-channel 210 to divide the first sub-channel 210 into two flow channels; the other third diversion strip 540 is disposed within the second sub-channel 220 to divide the second sub-channel 220 into two flow channels. Each third diversion strip 540 is connected to multiple second connectors 550, so that the third diversion strip 540 is connected to the fourth guardrail 510, the fifth guardrail 520, and the sixth guardrail 530 as a whole. The two flow channels of the first sub-channel 210 and the two flow channels of the second sub-channel 220 correspond to the two flow channels of the bottle inlet channel 100. When the first sub-channel 210 connects the bottle inlet channel 100 with a bottle outlet channel 300, the two flow channels of the bottle inlet channel 100, the two flow channels of the first sub-channel 210, and the two flow channels of the bottle outlet channel 300 are sequentially connected to form two continuous guide channels, significantly improving the conveying efficiency.

[0042] like Figure 5As shown, this application embodiment also provides a conveying device, including a first feeding mesh belt 600, a plurality of second feeding mesh belts 700, and a guardrail channel switching component as in any of the above embodiments, to have all the effects of the guardrail channel switching component. The first feeding mesh belt 600 is located below the bottle inlet channel 100, and each of the second feeding mesh belts 700 is located below one of the bottle outlet channels 300. Specifically, the first feeding mesh belt 600 and the second feeding mesh belts 700 partially overlap in the mesh belt flow direction and are adjacent to each other in the direction perpendicular to the mesh belt flow direction. When the switching channel 200 connects the bottle inlet channel 100 to one of the bottle outlet channels 300, a portion of the switching channel 200 is located above the first feeding mesh belt 600, and a portion of the second feeding mesh belts 700 is located above the second feeding mesh belts 700.

[0043] Taking the conversion channel 200 as an example when it is in the first station, at this time, the first sub-channel 210 connects the bottle inlet channel 100 with one of the bottle outlet channels 300, and the second sub-channel 220 does not connect with the bottle inlet channel 100. In application, after the vial leaves the filling machine, it flows on the first feed conveyor belt 600. When it flows to the guardrail channel switching component, it enters the bottle inlet channel 100. Driven by the first feed conveyor belt 600, the vial flows along the bottle inlet channel 100 and enters the first sub-channel 210. When the vial flows to the junction of the first feed conveyor belt 600 and the second feed conveyor belt 700, it is pushed by the other vials upstream and enters the second feed conveyor belt 700 along the first sub-channel 210. Driven by the second feed conveyor belt 700, it flows to the bottle outlet channel 300 connected to the first sub-channel 210, and then flows on the corresponding second feed conveyor belt 700 until it reaches the freeze dryer on one side of the second feed conveyor belt 700.

[0044] When switching to another freeze dryer, rotate the turntable guardrail 500 to position the transfer channel 200 in the second position. For example... Figure 6 As shown, at this time, the second sub-channel 220 connects the bottle inlet channel 100 with another bottle outlet channel 300, while the first sub-channel 210 is not connected to the bottle inlet channel 100. When the vial enters the bottle inlet channel 100, it flows along the bottle inlet channel 100 under the drive of the first feed mesh belt 600 and enters the second sub-channel 220. When the vial flows to the junction of the first feed mesh belt 600 and the second feed mesh belt 700, it is pushed by the other vials upstream and enters another second feed mesh belt 700 along the second sub-channel 220. Under the drive of the second feed mesh belt 700, it flows to the bottle outlet channel 300 connected to the second sub-channel 220, and then flows on the second feed mesh belt 700 until it reaches the freeze dryer on one side of the second feed mesh belt 700.

[0045] The above-described 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.
