Description

Technical Field

[0001] This application relates to the field of material conveying technology, and in particular to a conveying device and processing system. Background Technology

[0002] In continuous production processes in the food, pharmaceutical, and chemical industries, material handling is a crucial link connecting various processes. Its stability and the protection it provides to materials directly impact the quality of the final product and production efficiency. This is especially true in the production of pharmaceutical solid dosage forms (such as tablets). The process from tablet compression to coating or aluminum-plastic coating presents challenges related to tablet integrity, dust control, and material lifting. Currently, issues such as surface blackening, wear, chipping, and breakage may arise during material handling. Summary of the Invention

[0003] The main purpose of this application is to propose a conveying device and processing system, which aims to solve the technical problem that materials may be damaged during material conveying.

[0004] To achieve the above objectives, in a first aspect, this application proposes a conveying device, comprising: The cover has a side peripheral wall that encloses a cavity. The side peripheral wall is provided with an inlet and an outlet, both of which are connected to the cavity. Along the height direction of the cover, the height of the inlet is lower than the height of the outlet. A receiving component is disposed within the cavity and is used to receive materials. A first drive mechanism is configured to drive the receiving member to move along the height direction of the cover, so that the receiving member can move between the inlet and the outlet.

[0005] In some embodiments, the first drive mechanism includes a power element and a drive rod, the power element being configured to drive the drive rod to rotate along a first direction and a second direction, the first direction and the second direction being opposite to each other; The receiving member is connected to the drive rod, which is configured to drive the receiving member to move up and down. For example, when the drive rod rotates in the first direction, the receiving member rises with the drive rod, and when the drive rod rotates in the second direction, the receiving member descends with the drive rod.

[0006] In some embodiments, a protective cover is provided on the outer side of the drive rod, the protective cover being used to isolate the drive rod from the receiving member.

[0007] In some embodiments, the top of the cover is provided with an air blowing port, which communicates with the cavity and is adapted to be connected to an air blowing mechanism; the bottom of the cover is provided with an air suction port, which communicates with the cavity and is adapted to be connected to an air suction mechanism. The receiving component is provided with a filter port, through which impurities in the material can be discharged. The blowing mechanism can blow air into the cavity through the blowing port, so that impurities in the material received by the receiving member can be discharged through the filter port, and the discharged impurities can be sucked in by the suction mechanism through the suction port.

[0008] In some embodiments, a storage box is provided at the discharge port. The storage box includes a first storage cavity and a second storage cavity. A partition is provided between the first storage cavity and the second storage cavity. The partition is used for secondary screening of impurities in the material. The first storage cavity is used to store the material, and the second storage cavity is used to store the impurities.

[0009] In some embodiments, the conveying device further includes a first oscillator connected to the mesh, the first oscillator being used to vibrate the mesh to separate the material and the impurities on the mesh.

[0010] In some embodiments, the receiving member is provided with a discharge port, and the conveying device is provided with a second driving mechanism at the discharge port. The second driving mechanism includes a driving member and a baffle. The driving member is configured to drive the baffle to move along a third direction and a fourth direction, wherein the third direction and the fourth direction are opposite to each other. When the discharge port and the first storage cavity are aligned, the driving member drives the baffle to move along the third direction so that the baffle avoids the discharge port and realizes the communication between the discharge port and the first storage cavity; when the discharge port and the first storage cavity are not aligned, the driving member drives the baffle to move along the fourth direction so that the baffle blocks the discharge port.

[0011] In some embodiments, the conveying device further includes a conveying pipe and a second oscillator, the conveying pipe being in communication with the first storage cavity, and the second oscillator being connected to the conveying pipe for vibrating the conveying pipe to discharge the material inside the conveying pipe.

[0012] In some embodiments, the conveying device includes a first sensor, a second sensor, and a controller, wherein the first sensor and the second sensor are capable of transmitting position signals to the controller; The first sensor is located at the feed inlet and is used to monitor the position of the receiving component at the feed inlet. When the first sensor detects that the receiving component has reached the first target position, it transmits a first position signal to the controller so that the controller controls the first drive mechanism to stop driving the receiving component. The second sensor is located at the discharge port and is used to monitor the position of the receiving component at the discharge port. When the second sensor detects that the receiving component has reached the second target position, it transmits a second position signal to the controller so that the controller controls the first drive mechanism to stop driving the receiving component.

[0013] Secondly, this application proposes a processing system, comprising: The conveying device in any of the above embodiments; A feeding device is connected to the inlet of the conveying device and is used to feed materials into the cavity; A feeding device is connected to the discharge port of the conveying device and is used to feed the material into the cavity.

[0014] Compared with the prior art, the beneficial effects of this application are: In the technical solution of this application, due to the limitations of the discharge position of the upstream equipment, such as the discharge position of the upstream tablet press, the inlet height of this conveying device is set relatively low to ensure that the inlet of the conveying device can smoothly connect with the discharge position of the upstream equipment, thereby ensuring production continuity. During material conveying, the material is conveyed from the inlet into the housing and can naturally slide onto the receiving component. Then, the first drive mechanism drives the receiving component to rise along the height direction of the housing, that is, the first drive mechanism drives the receiving component to move upwards towards the discharge port. Finally, when the receiving component reaches the discharge port, the material received on the receiving component is conveyed to the outside of the housing through the discharge port, realizing the conveying of material to the next process.

[0015] When materials are conveyed from the inlet to the receiving component, and when materials are conveyed from the receiving component to the outside of the enclosure through the outlet, the materials are transferred by free-fall, without any pushing or pushing steps. Furthermore, the receiving component uses a static lifting principle to move the materials from the inlet to the outlet. Throughout these processes, the materials are not subjected to external forces, thus effectively preventing damage during transport and ensuring lossless material transfer.

[0016] The processing system using the above-mentioned conveying device can ensure the smooth and continuous conveying of materials during production, prevent the materials from being damaged during conveying, and improve the production quality and efficiency of materials.

Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

For example, "A and / or B" includes solution A, solution B, or a solution where A and B are simultaneously satisfied. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0024] In continuous production processes in the food, pharmaceutical, and chemical industries, material handling is a crucial link connecting various processes. Its stability and the protection it provides to materials directly impact the quality of the final product and production efficiency. This is especially true in the production of pharmaceutical solid dosage forms (such as tablets). The process from tablet compression to coating or aluminum-plastic coating presents challenges related to tablet integrity, dust control, and material lifting. Currently, issues such as surface blackening, wear, chipping, and breakage may arise during material handling.

[0025] Therefore, in order to solve the above problems, refer to Figures 1 to 3 This application provides a conveying device 10, which can convey materials such as tablets. The conveying device 10 includes a cover 100, a receiving member 200, and a first driving mechanism 300. The cover 100 has a side peripheral wall 110, which encloses a cavity 120. The side peripheral wall 110 is provided with an inlet 130 and an outlet 140, both of which communicate with the cavity 120. Along the height direction of the cover 100, the inlet 130 is positioned lower than the outlet 140. The receiving member 200 is disposed within the cavity 120 and is used to receive materials. The first driving mechanism 300 is configured to drive the receiving member 200 to move along the height direction of the cover 100, enabling the receiving member 200 to move between the inlet 130 and the outlet 140.

[0026] Specifically, in this embodiment, due to the limitations of the discharge position of the upstream equipment, such as the discharge position of the upstream tablet press, the inlet 130 of the conveying device 10 is set at a relatively low height to ensure that the inlet 130 of the conveying device 10 can smoothly connect with the discharge position of the upstream equipment, thereby ensuring production continuity. When conveying materials, the materials are conveyed from the inlet 130 into the cover 100 and can naturally slide onto the receiving member 200. Then, the first driving mechanism 300 drives the receiving member 200 to rise along the height direction of the cover 100, that is, the first driving mechanism 300 drives the receiving member 200 to rise towards the discharge port 140. Finally, the receiving member 200 reaches the position of the discharge port 140, and the materials received on the receiving member 200 are conveyed to the outside of the cover 100 through the discharge port 140, realizing the conveying of materials to the next process.

[0027] When materials are conveyed from the inlet 130 to the receiving component 200, and when materials are conveyed from the receiving component 200 to the outside of the cover 100 through the outlet 140, the materials are transferred by free sliding, without any pushing or pushing of the materials. Furthermore, the receiving component 200 uses a static lifting principle to move the materials from the inlet 130 to the outlet 140. During the above processes, the materials are not subjected to external forces, thus effectively preventing damage to the materials during conveying and ensuring lossless material transport.

[0028] In some embodiments, refer to Figure 1 and Figure 3 The first driving mechanism 300 includes a power element 310 and a drive rod 320. The power element 310 is configured to drive the drive rod 320 to rotate in a first direction and a second direction, which are opposite to each other. A receiving member 200 is connected to the drive rod 320. When the drive rod 320 rotates in the first direction, the receiving member 200 rises with the drive rod 320; when the drive rod 320 rotates in the second direction, the receiving member 200 falls with the drive rod 320. For example, the power element 310 can be a drive motor, and the drive rod 320 can be a drive screw connected to the drive shaft of the drive motor. The drive motor can drive the drive screw to rotate, thereby using the drive screw to drive the receiving member 200 to rise or fall.

[0029] One possible implementation is to refer to Figure 1 and Figure 3The drive rod 320 passes through the center of the receiving component 200, ensuring uniform force distribution and preventing overturning or shifting due to uneven force, thus improving the stability of the receiving component 200 during movement. The receiving component 200 may be connected to a lead screw nut, with the drive rod 320 passing through it. The lead screw nut has an anti-rotation lock, which allows the receiving component 200 to be stably positioned at a certain height, preventing it from falling due to gravity.

[0030] Specifically, in this embodiment, when the receiving member 200 transfers material from the inlet 130 to the outlet 140, the power element 310 drives the drive rod 320 to rotate in the first direction. At this time, the drive rod 320 can drive the receiving member 200 to rise, so that the receiving member 200 can move to the outlet 140. When the receiving member 200 moves from the outlet 140 to the inlet 130, the power element 310 drives the drive rod 320 to rotate in the second direction. At this time, the drive rod 320 can drive the receiving member 200 to fall, so that the receiving member 200 can move to the inlet 130.

[0031] By adopting the above-mentioned driving method, it is possible to ensure the smooth movement of the receiving component 200, prevent the material from rubbing or colliding during material conveying, thus ensuring that the material is not damaged, and also ensure the movement accuracy of the receiving component 200, so that the receiving component 200 can move precisely to the target position and smoothly realize the loading and unloading of materials.

[0032] In some embodiments, a protective cover (not shown) is provided on the outer side of the drive rod 320 to isolate the drive rod 320 from the receiving member 200. Exemplarily, the protective cover may be an accordion-style cover.

[0033] Specifically, in this embodiment, the protective cover can completely enclose the drive rod 320, completely isolating the risk of contact between the lead screw lubricant and the material, preventing the lubricant adhering to the drive rod 320 from dripping onto the material during the movement of the drive rod 320, thus avoiding cross-contamination of the material.

[0034] One possible implementation is that the drive rod 320 includes a first rod located above the receiving member 200 and a second rod located below the receiving member 200. A first protective cover is provided on the outer side of the first rod, and a second protective cover is provided on the outer side of the second rod. Both the first and second protective covers are accordion-style protective covers. One end of the first protective cover can be connected to the top of the receiving member 200, and the other end can be connected to the top of the cover body 100. One end of the second protective cover can be connected to the bottom of the receiving member 200, and the other end can be connected to the bottom of the cover body 100.

[0035] When the receiving component 200 rises, the first protective cover will compress while the second protective cover will extend, allowing the first and second protective covers to move with the receiving component 200. This prevents the receiving component 200 from getting tangled with the first and second protective covers during its ascent, ensuring the normal ascent of the receiving component 200.

[0036] Similarly, when the receiving component 200 descends, the first protective cover will extend and the second protective cover will compress, so that the first and second protective covers can move with the receiving component 200. This can prevent the receiving component 200 from getting tangled with the first and second protective covers during descent, and ensure the normal descent of the receiving component 200.

[0037] In some embodiments, refer to Figure 1 and Figure 3 The top of the cover 100 is provided with an air blowing port 150, which is connected to the cavity 120. The air blowing port 150 is suitable for connecting to an air blowing mechanism. The bottom of the cover 100 is provided with an air suction port 160, which is connected to the cavity 120. The air suction port 160 is suitable for connecting to an air suction mechanism. The receiving component 200 is provided with a filter port 210, through which impurities in the material can be discharged. The air blowing mechanism can blow air into the cavity 120 through the air blowing port 150, so that impurities in the material received by the receiving component 200 can be discharged through the filter port 210, and the discharged impurities can be sucked in by the air suction mechanism through the air suction port 160.

[0038] It should be noted that the filter port 210 has a small aperture, which means that the filter port 210 can only filter out small particles such as dust, ensuring that the material will not leak out from the filter port 210.

[0039] Specifically, in this embodiment, after the material is fed onto the receiving member 200, the blowing mechanism blows gas into the receiving member 200 in the cavity 120 through the blowing port 150 (for example, the gas can be a clean inert gas to prevent the gas and the material from reacting chemically). At this time, the fine particles such as dust in the material received by the receiving member 200 can leak out from the filter port 210 under the blowing action of the gas and be drawn and collected by the suction mechanism through the suction port 160.

[0040] The combined action of the blowing and suction mechanisms ensures that fine particles such as dust in the material inside the cavity 120 and on the receiving part 200 are sucked out, thereby ensuring the cleanliness of the material inside the cavity 120 and on the receiving part 200 and preventing the material from being contaminated by dust, which would lead to a decline in the quality of the material.

[0041] In some embodiments, a storage box (not shown in the figure) is provided at the discharge port 140. The storage box includes a first storage cavity and a second storage cavity, and a partition is provided between the first storage cavity and the second storage cavity. The partition is used for secondary screening of impurities in the material. The first storage cavity is used to store the material, and the second storage cavity is used to store the impurities.

[0042] It should be noted that the aperture of the mesh is slightly larger than that of the filter port 210. The mesh can filter out broken or damaged materials (for example, if the material is damaged, its size will definitely be smaller, and it can then leak out through the mesh), thereby ensuring the consistency of material size.

[0043] Specifically, in this embodiment, when the receiving component 200 unloads the material, the material is first temporarily stored in a storage box, for example, in the first storage cavity of the storage box. Since the first and second storage cavities are separated only by a mesh, any damaged or broken material in the first storage cavity will leak into the second storage cavity through the mesh, ensuring the structural integrity and consistent size of the material in the first storage cavity, thus improving the quality and appearance of the material.

[0044] In some embodiments, the conveying device 10 further includes a first oscillator (not shown in the figure), which is connected to a mesh screen and is used to vibrate the mesh screen to separate the material and impurities on the mesh screen. It should be noted that the impurities here mainly refer to damaged or broken materials, or may also include fine particles such as dust mixed in with the material.

[0045] Specifically, in this embodiment, the first oscillator can vibrate the mesh, causing the material on the mesh to vibrate. During the vibration process, it is beneficial to achieve uniform mixing of the material, ensuring that defective or damaged material can effectively leak out from the mesh openings of the mesh, improving the sorting efficiency and effect of the material, and ensuring the quality of the material in the first storage cavity.

[0046] Understandably, the vibration frequency, amplitude, and other parameters of the first oscillator need to match the physical properties of the material, such as hardness and brittleness, to prevent the first oscillator from causing further damage to the material.

[0047] In some embodiments, refer to Figures 1 to 3The receiving component 200 is provided with a discharge port 220. The conveying device 10 is provided with a second driving mechanism 400 at the discharge port 220. The second driving mechanism 400 includes a driving component 410 and a baffle 420. The driving component 410 is configured to drive the baffle 420 to move along a third direction and a fourth direction, which are opposite to each other. Specifically, when the discharge port 220 is aligned with the first storage cavity, the driving component 410 drives the baffle 420 to move along the third direction, so that the baffle 420 avoids the discharge port 220, realizing the connection between the discharge port 220 and the first storage cavity; when the discharge port 220 and the first storage cavity are not aligned, the driving component 410 drives the baffle 420 to move along the fourth direction, so that the baffle 420 blocks the discharge port 220. For example, the driving component 410 can be a drive motor or a drive cylinder.

[0048] Specifically, in this embodiment, under normal circumstances, the baffle 420 can block the discharge port 220, ensuring that the receiving member 200 can transport materials without leakage. When material needs to be discharged, the discharge port 220 and the first storage chamber are in a connected state. At this time, the material on the receiving member 200 can be transported to the storage box, where the material can be temporarily stored and sorted. Using the above structure, the continuity of material transport can be ensured, and the material can be purged and screened in different production processes, improving the production quality and efficiency.

[0049] In some embodiments, refer to Figure 2 The drive unit 410 can adjust the angle of the baffle 420, thereby adaptively adjusting the opening size of the discharge port 220. When conveying larger materials, the drive unit 410 can adjust the baffle 420 at a larger angle, making the opening of the discharge port 220 larger and preventing material blockage at the discharge port 220. When conveying smaller materials, the drive unit 410 can adjust the baffle 420 at a smaller angle, making the opening of the discharge port 220 smaller, reducing the conveying speed of the material at the discharge port 220, and avoiding damage to the material due to excessive conveying speed.

[0050] In some embodiments, refer to Figure 1 and Figure 3 The conveying device 10 also includes a conveying pipe 500 and a second oscillator (not shown in the figure). The conveying pipe 500 is connected to the first storage cavity, and the second oscillator is connected to the conveying pipe 500 to vibrate the conveying pipe 500 so that the material in the conveying pipe 500 is discharged.

[0051] Specifically, in this embodiment, after the material in the first storage cavity is screened, the material in the first storage cavity can be conveyed into the conveying pipe 500, and the material can be unloaded using the conveying pipe 500. For example, the screen can be driven by a structure such as a drive motor. During unloading, the drive motor can drive the screen to tilt so that the material can be conveyed from the first storage cavity into the conveying pipe 500 under its own weight.

[0052] The second oscillator can vibrate the conveying pipe 500 to ensure that the material will not be blocked in the conveying pipe 500 during the conveying process, thereby improving the material feeding efficiency of the conveying device 10 and ensuring the continuity of material conveying by the conveying device 10.

[0053] One possible implementation is that the connection end between the conveying pipe 500 and the discharge port 140 is provided with a spherical bearing, so that the conveying pipe 500 and the cover 100 are hinged, thereby facilitating the free adjustment of the length of the conveying pipe 500 or the angle between the conveying pipe 500 and the cover 100 according to the conveying distance or conveying direction, so as to improve the applicability of the conveying device 10.

[0054] Understandably, the vibration frequency, amplitude, and other parameters of the second oscillator need to match the physical properties of the material, such as hardness and brittleness, to prevent the second oscillator from causing further damage to the material.

[0055] In some embodiments, the conveying device 10 includes a first sensor, a second sensor, and a controller (not shown). The first and second sensors are capable of transmitting position signals to the controller. The first sensor is disposed at the feed inlet 130 and is used to monitor the position of the receiving member 200 at the feed inlet 130. When the first sensor detects that the receiving member 200 has reached a first target position, it transmits a first position signal to the controller, so that the controller controls the first drive mechanism 300 to stop driving the receiving member 200. The second sensor is disposed at the discharge outlet 140 and is used to monitor the position of the receiving member 200 at the discharge outlet 140. When the second sensor detects that the receiving member 200 has reached a second target position, it transmits a second position signal to the controller, so that the controller controls the first drive mechanism 300 to stop driving the receiving member 200.

[0056] Specifically, in this embodiment, the first sensor and the second sensor can monitor the position of the receiving component 200. Only when the receiving component 200 moves to the target position will the first sensor and the second sensor transmit position signals to the controller. The controller can control the start and stop of the first drive mechanism 300, thereby ensuring the movement accuracy of the receiving component 200, improving the alignment accuracy of the receiving component 200 with the inlet 130 and the outlet 140, and improving the stability of material conveying.

[0057] In some embodiments, the connection structures between the partition net and the storage box, and between the conveying pipe 500 and the cover 100, can adopt detachable connection methods such as snap-fit, so as to facilitate the installation or disassembly of components, and to enable timely cleaning of components, ensuring the cleanliness of the conveyed materials and preventing the materials from being contaminated.

[0058] Correspondingly, another embodiment of this application also provides a processing system that can be used to produce materials such as tablets. The processing system includes the conveying device 10 in any of the above embodiments, and also includes a feeding device and a discharging device. The feeding device is connected to the inlet 130 of the conveying device 10 and is used to feed materials into the cavity 120. The discharging device is connected to the outlet 140 of the conveying device 10 and is used to discharge the materials from the cavity 120.

[0059] Specifically, in this embodiment, the processing system using the above-mentioned conveying device 10 can ensure the smoothness and continuity of material conveying during production, ensure that the material is not damaged during conveying, and improve the production quality and efficiency of the material.

[0060] Thanks to the improvements to the conveying device 10 described above, the processing system of this embodiment has the same technical effects as the conveying device 10 described above, which will not be repeated here.

[0061] It should be noted that other undisclosed aspects of the conveying device 10 and processing system provided in this application can be found in the prior art, and will not be repeated here.
