Abstract
Description
Technical Field
[0001] This utility model relates to the field of material conveying, and in particular to a material conveying device. Background Technology
[0002] In pharmaceutical manufacturing, material weighing is a crucial step in ensuring product quality and dosage accuracy. Currently, the industry commonly uses a manual weighing method. The process involves operators manually removing materials (such as vials and packaging boxes) from the operating equipment and transferring them to a separate weighing device (such as an electronic scale) for weighing before returning them to the production line for subsequent processes. However, this manual handling and weighing process frequently interrupts the continuous operation of the roller conveyor, leading to longer production cycles, reduced overall efficiency, and difficulty meeting the high-capacity demands of modern pharmaceutical manufacturing. Furthermore, direct contact between personnel and materials and the production environment can cause cross-contamination or microbial contamination, especially in aseptic formulation production, where this issue seriously threatens drug safety and regulatory compliance (such as GMP requirements).

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0026] 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.
[0027] Figure 1This is a schematic structural diagram of a material conveying device provided in an embodiment of this utility model. Figure 1 As shown, and refer to Figures 2 to 6 The present invention provides a material conveying device, including a conveyor line 100 and a weighing component 200. The conveyor line 100 is used to convey a product 300 to be conveyed. The conveyor line 100 includes a conveying component 110 that can move up and down. The weighing component 200 is disposed below the conveying component 110 and is configured to carry the product 300 to be conveyed and weigh the product 300 to be conveyed when the conveying component 110 moves down.
[0028] like Figure 1 , Figure 2 As shown in this embodiment of the invention, a weighing component 200 is installed below the vertically movable conveying component 110. When the product 300 to be conveyed is conveyed onto the conveying component 110, the conveying component 110 is controlled to descend, causing the product 300 to fall onto the weighing component 200, allowing the weighing component 200 to weigh the product 300. After weighing, the conveying component 110 rises, conveying the product 300 normally. Through the cooperation of the conveying component 110 and the weighing component 200, the product 300 can be weighed quickly, improving conveying efficiency; at the same time, the weighing process does not involve direct human contact with the product 300, reducing the risk of contamination.
[0029] like Figure 4 As shown, in one embodiment of this utility model, the conveying assembly 110 includes a plurality of drive rollers 111 that rotate in a preset direction. Any two adjacent drive rollers 111 are spaced apart to form a transmission gap 112 between them. The adjacent drive rollers 111 are connected by a belt drive. Specifically, the conveying assembly 110 also includes a frame 113, on which the drive rollers 111 are rotatably mounted. The conveying line 100 may also include a fixed roller assembly 120, which is positioned upstream and / or downstream of the conveying assembly 110 along the conveying direction for feeding and / or discharging materials. Figure 2 As shown, the fixed roller assembly 120 is disposed downstream of the conveying assembly 110 along the conveying direction, and a transition roller assembly 130 is also disposed between the fixed roller assembly 120 and the conveying assembly 110.
[0030] Furthermore, such as Figure 3As shown, the weighing assembly 200 includes an electronic scale 210 and multiple support claws 220, which are disposed on the weighing pan of the electronic scale 210. Each support claw 220 is located within or below a transmission gap 112, so that when the conveying assembly 110 moves downward, the support claw 220 passes through the transmission gap 112 to carry the product 300 to be conveyed. Specifically, the weighing assembly 200 also includes a base 230 and a telescopic rod 240, which is disposed on the base 230, and the height of the base 230 is controlled by the extension and retraction of the telescopic rod 240. The electronic scale 210 is disposed on the base 230.
[0031] When the product 300 is conveyed onto the conveying assembly 110, the conveying assembly 110 lowers the product 300 until it contacts the support claw 220. As the conveying assembly 110 continues to descend, the product 300 is held on the support claw 220, and the electronic scale 210 weighs it. After weighing, the conveying assembly 110 rises, and the product 300 contacts the drive roller 111 and separates from the support claw 220 until the conveying assembly 110 resets and continues conveying.
[0032] like Figure 2 , 4 As shown, in one embodiment of this utility model, the material conveying device further includes a light sensor 510, a first cylinder 520, and a baffle 530. The light sensor 510 is disposed on the conveying assembly 110 and is used to detect the position of the product 300 to be conveyed on the conveying assembly 110. The first cylinder 520 has an output end that outputs vertical reciprocating motion. The first cylinder 520 is disposed below the transmission gap 112 at the downstream end of the transmission roller 111, and the baffle 530 is connected to the output end of the first cylinder 520. Specifically, the light sensor 510 is disposed on the inner side of the frame 113.
[0033] In application, when the light sensor 510 detects that the product 300 to be conveyed is about to reach the position of the baffle 530, it can transmit the signal to the first cylinder 520 through the PLC. After receiving the signal, the first cylinder 520 controls the output terminal to rise, raising the baffle 530 onto the drive roller 111 to block the product 300 to be conveyed from continuing to move, so that the product 300 to be conveyed stops directly above the electronic scale 210 to ensure the accuracy of subsequent weighing; then the drive roller 111 can be controlled to stop transmission, and the conveying assembly 110 can be controlled to drive the product 300 to descend.
[0034] In one embodiment of this utility model, the conveyor line 100 further includes a base 400 and a lifting device 600, the lifting device 600 being fixed on the base 400; the lifting device 600 includes a second cylinder 610, the piston rod 611 of the second cylinder 610 extending vertically for connecting the conveying assembly 110. In application, the movement of the conveying assembly 110 is controlled by controlling the movement of the piston rod 611.
[0035] like Figure 5 As shown, in one embodiment of this utility model, the lifting device 600 further includes a lifting plate 620, a drive rod 630, a lifting plate 640, and a support rod 650. The lifting plate 620 is disposed on the piston rod 611; there are at least two drive rods 630, spaced apart on the lifting plate 620; the lifting plate 640 is disposed on the top of the drive rod 630; there are at least two support rods 650, which are evenly disposed on the lifting plate 640, and the top of the support rod 650 is connected to the frame 113 of the conveying assembly 110. The piston rod 611, lifting plate 620, drive rod 630, lifting plate 640, support rod 650, and conveying assembly 110 are arranged sequentially from bottom to top to facilitate transmission. The presence of two drive rods 630 allows for even transmission and avoids the problem of the lifting plate 640 easily tilting when there is only one drive rod 630. Preferably, there are four support rods 650, which are distributed at the four corners of the lifting plate 640 so that the conveying assembly 110 is subjected to uniform force.
[0036] Furthermore, the base 400 includes a lower plate 410, an upper plate 420, and a connector 430. The lower plate 410 and the upper plate 420 are spaced apart, and the two ends of the connector 430 are connected to the lower plate 410 and the upper plate 420 respectively. The second cylinder 610 is disposed on the lower plate 410, the lifting plate 620 is located below the upper plate 420, and the lifting plate 640 is located above the upper plate 420. The upper plate 420 is provided with a through hole 421, and the drive rod 630 passes through the through hole 421. This configuration allows for the installation of an isolator on the upper plate 420, sealing both the weighing component 200 and the conveying component 110 within the isolator, thus reducing the risk of contamination of the product 300 to be conveyed. Furthermore, since the second cylinder 610 contains lubricating oil and is prone to generating debris, placing it outside the isolator and transmitting it via the lifting plate 620, drive rod 630, lifting plate 640, and support rod 650 further reduces the risk of contamination of the product 300 to be conveyed.
[0037] like Figure 5 , 6As shown, in one embodiment of this utility model, the lifting device 600 further includes a sealing sleeve 660, which is disposed on the upper plate layer 420 and communicates with the through hole 421; the sealing sleeve 660 includes a fixing seat 661, a cylinder 662 and a sealing ring 663, the fixing seat 661 is detachably disposed on the upper plate layer 420, the cylinder 662 is connected to the fixing seat 661, and the driving rod 630 is spaced apart from the inner wall of the cylinder 662; the sealing ring 663 is disposed inside the cylinder 662 and sleeved on the driving rod 630.
[0038] In this embodiment, to facilitate the up-and-down movement of the drive rod 630, the drive rod 630 and the through hole 421 should be in clearance fit. To prevent external dust and other debris from entering the isolator, a sealing sleeve 660 is added. A first O-ring 668 is provided between the fixing seat 661 and the cylinder 662 of the sealing sleeve 660 to provide a seal between the fixing seat 661 and the cylinder 662; the sealing ring 663 provides a seal between the cylinder 662 and the drive rod 630.
[0039] Furthermore, the sealing sleeve 660 also includes a sliding bearing 664, which is coaxially disposed inside the cylinder 662 and sleeved on the drive rod 630. The sliding bearing 664 is located between the sealing ring 663 and the fixed seat 661, which can reduce friction when the drive rod 630 moves up and down, ensuring smooth operation of the device. A groove is provided at the end of the cylinder 662 away from the fixed seat 661, and the groove is coaxial with the cylinder 662. From the bottom to the opening of the groove, a sealing ring pressure plate 665, a sealing ring 663, and a sealing ring cover 666 are arranged in sequence. The sealing ring pressure plate 665 and the sealing ring cover 666 are used to limit the sealing ring 663 and prevent the sealing ring 663 from moving with the drive rod 630. A dustproof ring 667 is provided at the top of the sealing ring cover 666, located between the sealing ring cover 666 and the drive rod 630, to prevent dust and other debris from passing through the gap between the sealing ring cover 666 and the drive rod 630. A second O-ring 669 is provided between the cylinder 662 and the sealing ring cover 666 to provide a seal between the cylinder 662 and the sealing ring cover 666.
[0040] In one embodiment of this utility model, the lifting device 600 further includes a first limiting post 670, which is disposed on one side of the second cylinder 610 and located below the lifting plate 620. The first limiting post 670 is configured to abut against the lifting plate 620 when the piston rod 611 retracts. When the piston rod 611 retracts, the lifting plate 620 descends to contact the first limiting post 670 and is then restricted from descending further, thus preventing the drive rod 630 from having an excessive stroke and affecting the sealing performance. In addition, the lifting device 600 also includes a second limiting post 680, which is disposed on the lower surface of the upper plate layer 420. When the piston rod 611 extends, the lifting plate 620 rises to contact the second limiting post 680 and is then restricted from rising further, so that the conveying assembly 110, the fixed roller assembly 120, and the transition roller assembly 130 are on the same plane, which facilitates transportation.
[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.
