Description

Technical Field

[0001] This application relates to the field of medical material production technology, and in particular to a feeding device. Background Technology

[0002] Medical supplies such as vials and cartridges are typically placed in batches on pallets before being loaded. Currently, pallet loading usually involves manual placement of pallets containing materials one by one onto a conveyor, with subsequent equipment removing the pallets one by one from the conveyor. Loading large quantities of materials requires continuous manual loading, resulting in a heavy workload for workers and is time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of this application is to provide a feeding device that allows workers to stack multiple pallets into a pallet group and move them onto the pallet support assembly at once, reducing labor intensity and saving time and effort.

[0004] The embodiments of this application can be implemented as follows:

[0005] This application provides a feeding device, including a frame, a lifting mechanism, and a conveying mechanism;

[0006] The conveying mechanism includes a conveying drive assembly, a conveying assembly, and a tray assembly;

[0007] Two conveying components are mounted side by side on the frame along a first horizontal direction, and the pallet assembly is connected to the side of each conveying component that is close to each other. The two pallet assemblies opposite each other in the first horizontal direction are used to jointly support the pallet.

[0008] The conveying drive assembly is mounted on the frame and connected to the conveying assembly. The conveying drive assembly is used to drive the conveying assembly to move so that the conveying assembly drives the pallet assembly to move along the second horizontal direction to the lifting position, wherein the first horizontal direction and the second horizontal direction are perpendicular.

[0009] The lifting mechanism includes a connected lifting drive assembly and a lifting member. The lifting drive assembly is disposed on the frame, and the lifting member can lift the pallet under the drive of the lifting drive assembly.

[0010] In the above embodiment, two conveying components are mounted side by side on the frame along a first horizontal direction, so that the space between the two conveying components can accommodate the pallets. Since the pallet-bearing components are connected to the sides of the two conveying components that are close to each other, the two pallet-bearing components opposite each other in the first horizontal direction can jointly carry multiple pallets containing materials and stacked together. In this way, workers can stack multiple pallets into a pallet group and move them onto the pallet-bearing components at once, which reduces the amount of labor and saves time and effort.

[0011] The two conveying components work synchronously to move the pallet along the second horizontal direction to the lifting station. After the pallet reaches the lifting station, the lifting component is first located below the entire pallet group. Then, the lifting drive component drives the pallet upward, so that the entire pallet moves upward. This makes it easier for the downstream equipment to take away the highest pallet in the pallet group. After the downstream equipment takes away the pallet, the lifting drive component continues to drive the lifting component to rise. This cycle continues until all the pallets on the pallet support component are taken away.

[0012] In an optional embodiment, the transmission assembly includes a drive shaft, a driven shaft, and a transmission component, wherein the transmission component includes a chain or a timing belt;

[0013] Both the drive shaft and the driven shaft are vertically and rotatably mounted on the frame, and the drive shaft and the driven shaft are spaced apart along the second horizontal direction;

[0014] The transmission component is wound around the drive shaft and the driven shaft;

[0015] The bearing assembly is fixed to the transmission component;

[0016] The conveying drive assembly is connected to the drive shaft and is used to drive the drive shaft to rotate;

[0017] The drive shafts in the two conveying components rotate in opposite directions.

[0018] The above-described implementation method transmits the power provided by the conveying drive assembly to the pallet assembly through chain drive or belt drive, which is low-cost for long-distance transmission and simple to maintain. Since the drive shafts in the two conveying assemblies rotate in opposite directions, the two transmission components move in the same direction when they are close to each other. This ensures that the pallet assembly in the middle of the two conveying assemblies moves in the same direction, thereby enabling the pallet group to move smoothly.

[0019] In an alternative embodiment, a plurality of the bearing assemblies are distributed circumferentially along the transmission member.

[0020] In the above embodiment, when the drive shaft rotates under the drive of the conveyor drive assembly, the bearing plate assembly moves around the drive shaft and the driven shaft together with the transmission component. The conveyor drive assembly only needs to provide torque in one direction and does not need to change the output torque direction of the conveyor drive assembly, thus extending the service life of the conveyor drive assembly.

[0021] In an optional embodiment, the feeding device further includes a detector located above one of the conveying components, the conveying drive component being able to stop if the detector detects a human body.

[0022] In the above implementation, a detector is used to detect the human body. This makes it easier for the human body to be detected when the worker carries the pallet across the detector. At this time, the conveying drive component stops, and the corresponding transmission components and pallet assembly also stop, so that the pallet assembly can be placed into the pallet assembly.

[0023] In an optional embodiment, the pallet assembly includes a base plate and a vertically connected upright plate to the base plate, the upright plate being connected to the conveying assembly; the base plate is used to support the bottom surface of the pallet, and the upright plate is used to limit the sides of the pallet.

[0024] In the above implementation, the pallet is supported by the base plate and the pallet is limited on the sides by the upright plate, so that the pallet can be transported stably on the pallet support assembly without shaking.

[0025] In an optional embodiment, the pallet is rectangular; the upright has an L-shaped cross-section and includes a first plate and a second plate connected at an angle, the first plate being connected to the conveying assembly; the inside corner between the first plate and the second plate is used for placing a corner portion of the pallet; wherein, the pallet-bearing assembly includes two uprights spaced apart along the second horizontal direction, the inside corners of the two uprights facing each other.

[0026] In the above embodiment, L-shaped uprights correspond to the corners of the pallet. The first plate, the second plate, and the bottom plate can jointly restrict the movement of one corner of the pallet. Since a pallet support assembly has two uprights, and the inside corners of these two uprights are opposite each other, a pallet support assembly can restrict two corners of the pallet. In this way, two pallet support assemblies opposite each other in the first horizontal direction can restrict the position of the entire pallet and ensure the stable bearing of the pallet.

[0027] In an optional implementation, in the two pallet assemblies opposite each other in the first horizontal direction, the height of the upright plate of one of them is greater than the height of the upright plate of the other.

[0028] In the above embodiment, by designing the upright plate of one side of the pallet assembly in the first horizontal direction to be shorter and the upright plate of the other side of the pallet assembly in the first horizontal direction to be taller, it is convenient for workers to move the pallet assembly from the lower upright plate to between the two conveying components in the first horizontal direction, and then place it into the pallet assemblies on both sides.

[0029] In an optional embodiment, the feeding device further includes a clamping mechanism, which is fixed to the frame;

[0030] The clamping mechanism is used to clamp or release the pallet when only one pallet remains on the pallet assembly.

[0031] In the above embodiment, the last pallet is clamped by a clamping mechanism. As the downstream equipment removes the pallet, the lifting component can descend via the lifting drive assembly. This allows the next batch of pallets to be transported by the conveying assembly and positioned above the lifting component at the lifting station. After the downstream equipment removes the last pallet of the previous batch, the lifting component can then lift the next batch of pallets, thus providing pallets to subsequent downstream equipment without interruption.

[0032] In an optional embodiment, the clamping mechanism includes two pushers arranged along the first horizontal direction, the two pushers being located on opposite sides of the two conveying components; the two pushers can move closer or further apart to clamp or release the tray together.

[0033] In the above embodiment, by arranging two pushers along a first horizontal direction and respectively located on the side of the two conveying components that are far apart from each other, the two pushers can clamp the tray when they are close to each other and release the tray when they are far apart, so that the downstream equipment can take it away.

[0034] In an optional embodiment, the clamping mechanism further includes two supports located on opposite sides of the two conveying components, respectively, away from each other;

[0035] The pushing component includes a tray and a driving component. The driving component is fixed on the support and connected to the tray. The driving component is used to drive the tray to move along the first horizontal direction.

[0036] In the above embodiment, a support member is used for the installation of the pushing member, so that the entire pushing member can be raised to match the height when the lifting member lifts the last pallet. The driving member drives the pallet to move along the first horizontal direction, so that the distance between the two pushing members can be shortened or lengthened, thereby achieving the effect of clamping or releasing the pallet.

[0037] In an optional embodiment, the feeding device further includes a detection element disposed on the clamping mechanism, which can clamp the pallet when the detection element detects that only one pallet remains.

[0038] In the above implementation, a detection component is used to identify whether there is only one pallet left on the lifting component. When it is identified that there is only one pallet left, the clamping mechanism clamps the pallet, so that the lifting component can descend to receive the next batch of pallets.

[0039] In an optional embodiment, the lifting drive assembly includes a lifting drive motor and a lifting transmission assembly. The lifting drive motor is fixed to the frame and connected to the lifting transmission assembly. The lifting transmission assembly is connected to the lifting member and is used to convert the torque of the lifting drive motor into a linear driving force that causes the lifting member to rise and fall.

[0040] In the above implementation, a stable torque is provided by a lifting drive motor, and the torque is converted into linear driving force by a lifting transmission assembly to drive the lifting component to move up and down smoothly. Moreover, the lifting transmission assembly can also amplify the power, reduce the load on the lifting drive motor, and extend its service life. Attached Figure Description

[0056] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0057] refer to Figures 1 to 3 This application discloses a feeding device, which includes a frame 100, a lifting mechanism 300 and a conveying mechanism 200;

[0058] The conveying mechanism 200 includes a conveying drive assembly, a conveying assembly 210, and a tray assembly 230;

[0059] Two conveying components 210 are mounted side-by-side on the frame 100 along a first horizontal direction X, and each of the two conveying components 210 is connected to a tray support component 230 on the side closest to it. The two tray support components 230 facing each other in the first horizontal direction X are used to jointly support a tray 700. In other words, the two conveying components 210 can be regarded as a first conveying component 214 and a second conveying component 215, respectively, and the first conveying component 214 and the second conveying component 215 are arranged side-by-side at intervals along the first horizontal direction X. The tray support component 230 connected to the first conveying component 214 is the first tray support component 233, and the tray support component 234 connected to the second conveying component 215 is the second tray support component 234. In this way, the first tray support component 233 and the second tray support component 234 facing each other in the first horizontal direction X jointly support a set of trays 710.

[0060] The conveyor drive assembly is mounted on the frame 100 and connected to the conveyor assembly 210. The conveyor drive assembly is used to drive the conveyor assembly 210 to run, so that the conveyor assembly 210 drives the pallet assembly 230 to move along the second horizontal direction Y to the lifting position, wherein the first horizontal direction X and the second horizontal direction Y are perpendicular.

[0061] The lifting mechanism 300 includes a connected lifting drive assembly 310 and a lifting component 320. The lifting drive assembly 310 is disposed on the frame 100. When the pallet 700 is in the lifting position, the lifting component 320 can lift the pallet 700 under the drive of the lifting drive assembly 310.

[0062] In this way, the two conveying components 210 are mounted side by side on the frame 100 along the first horizontal direction X. The space between the two conveying components 210 can accommodate the pallets 700. Since the pallet support components 230 are connected to the sides of the two conveying components 210 that are close to each other, the two pallet support components 230 that are opposite each other in the first horizontal direction X can jointly support multiple pallets 700 that are filled with materials and stacked. In this way, workers can stack multiple pallets 700 into a pallet group 710 and move them onto the pallet support components 230 at once, which reduces the workload and saves time and effort.

[0063] The two conveying components 210 work synchronously to move the pallet 700 along the second horizontal direction Y to the lifting position. After the pallet 700 reaches the lifting position, the lifting component 320 is first located below the entire pallet group 710, and then the lifting drive component 310 drives the pallet 700 upward so that the entire pallet 700 moves upward. This makes it convenient for the downstream equipment to take away the highest pallet 700 in the pallet group 710. After the downstream equipment takes away the pallet 700, the lifting drive component 310 continues to drive the lifting component 320 to rise. This cycle continues until all the pallets 700 on the pallet support component 230 are taken away.

[0064] Specifically, please refer to Figures 1 to 3 The transmission assembly 210 includes a drive shaft 211, a driven shaft 212, and a transmission component 213. The transmission component 213 includes a chain or a synchronous belt. The drive shaft 211 and the driven shaft 212 are both vertically rotatably mounted on the frame 100, and the drive shaft 211 and the driven shaft 212 are spaced apart along the second horizontal direction Y.

[0065] The transmission component 213 is wound around the drive shaft 211 and the driven shaft 212; the bearing assembly 230 is fixed to the transmission component 213; the conveying drive assembly is connected to the drive shaft 211 and is used to drive the drive shaft 211 to rotate; wherein, the drive shafts 211 in the two conveying assemblies 210 rotate in opposite directions.

[0066] In this embodiment, the power provided by the conveying drive assembly is transmitted to the tray assembly 230 through chain drive or belt drive, which is low-cost for long-distance transmission and simple to maintain. Since the drive shafts 211 in the two conveying assemblies 210 rotate in opposite directions, the two transmission components 213 move in the same direction when they are close to each other. This ensures that the tray assembly 230 in the middle of the two conveying assemblies 210 also moves in the same direction, thereby enabling the smooth translation of the tray group 710.

[0067] Of course, in order to ensure the reliable installation of the conveying assembly 210 on the frame 100, a conveying mounting frame 110 extending along the second horizontal direction Y is provided on the frame 100, and the drive shaft 211 and the driven shaft 212 are respectively rotatably located at both ends of the conveying mounting frame 110.

[0068] The number of transmission components 213 can be two or more, and they are vertically spaced apart. In this way, the connection reliability between the bearing assembly 230 and the transmission assembly 210 can be guaranteed by connecting two or more transmission components 213 to the bearing assembly 230 at the same time.

[0069] Optionally, multiple bearing assemblies 230 are distributed circumferentially along the transmission member 213, with each first bearing assembly 233 and a second bearing assembly 234 facing each other in the first horizontal direction X, that is, the first bearing assembly 233 and the second bearing assembly 234 correspond one-to-one.

[0070] When the drive shaft 211 rotates under the drive of the conveyor drive assembly, the bearing assembly 230 will move around the drive shaft 211 and the driven shaft 212 together with the transmission component 213. The conveyor drive assembly only needs to provide torque in one direction, without changing the output torque direction of the conveyor drive assembly, thus extending the service life of the conveyor drive assembly.

[0071] Continue to refer to Figure 1 and Figure 2 The loading device also includes a detector 600, which is located above a conveying assembly 210. The conveying drive assembly can stop when the detector 600 detects a human body. By using the detector 600 to detect the human body, it is convenient for workers carrying pallets 700 to cross the detector 600. When the human body is detected by the detector 600, the conveying drive assembly stops, and the corresponding transmission component 213 and pallet assembly 230 stop, so that the pallet assembly 710 can be placed into any pair of opposite pallet assemblies 230 in the first horizontal direction X.

[0072] The detector 600 can be a light curtain, an infrared sensor, or something similar, as long as it can emit a pulse signal when it is blocked, and the drive component can stop according to the pulse signal.

[0073] The drive components include, but are not limited to, motors, which facilitate control and provide stable and continuous torque.

[0074] Of course, it is understandable that the method of conveying the pallet 700 is not limited to the chain drive or belt drive mentioned above. In some embodiments, the conveying component 210 can also be a screw pair, rack pair or other components to drive the pallet assembly 230 to translate.

[0075] Optionally, the pallet assembly 230 includes a base plate 231 and a vertical plate 232 connected to the base plate 231. The vertical plate 232 is connected to the conveying assembly 210. The base plate 231 is used to support the bottom surface of the pallet 700, and the vertical plate 232 is used to limit the sides of the pallet 700.

[0076] Thus, the pallet 700 is supported by the base plate 231 and the pallet 700 is limited on the side by the upright plate 232, so that the pallet 700 can be transported stably on the pallet support assembly 230 without shaking.

[0077] More specifically, the pallet 700 is roughly rectangular in shape; in order to accommodate the shape of the pallet 700 and ensure that the corners of the pallet 700 are fully limited by the upright plate 232, the cross-section of the upright plate 232 is designed to be L-shaped.

[0078] Specifically, the upright plate 232 includes a first plate body 2320 and a second plate body 2321 that are vertically connected. The first plate body 2320 is connected to the conveying assembly 210. The inside corner side between the first plate body 2320 and the second plate body 2321 is used for placing a corner of the pallet 700.

[0079] The bearing assembly 230 includes two vertical plates 232 arranged at intervals along the second horizontal direction Y. The inner angle sides of the two vertical plates 232 (the inner angle between the first plate 2320 and the second plate 2321 is the inner angle, and the corresponding outer angle between the first plate 2320 and the second plate 2321 is the outer angle) are opposite each other.

[0080] In other words, a bearing assembly 230 contains two upright plates 232, which are respectively regarded as the first upright plate 2322 and the second upright plate 2323. The second plate body 2321 in the first upright plate 2322 and the second plate body 2321 in the second upright plate 2323 are directly opposite and parallel in the second horizontal direction Y. Thus, the inside corner side of the first upright plate 2322 and the inside corner side of the second upright plate 2323 are opposite each other, and the angle bisectors of the inside corners of the first upright plate 2322 and the second upright plate 2323 are perpendicular.

[0081] In this way, by using the L-shaped upright plate 232 to correspond to the corner of the pallet 700, the first plate 2320, the second plate 2321, and the bottom plate 231 can jointly restrict the movement of one corner of the pallet 700. Since one pallet support assembly 230 has two upright plates 232, and the inside corners of these two upright plates 232 are opposite each other, one pallet support assembly 230 can restrict two corners of the pallet 700. Thus, the two pallet support assemblies 230 that are opposite each other in the first horizontal direction X can restrict the position of the entire pallet 700 and ensure the stable bearing of the pallet 700.

[0082] Of course, in some embodiments, depending on the angle of the corner of the tray 700, the angle between the first plate 2320 and the second plate 2321 can also be an acute angle or an obtuse angle, and the angle bisectors of the respective internal angles of the first upright plate 2322 and the second upright plate 2323 are obtuse or acute angles.

[0083] In addition, it should be noted that in some embodiments, the upright plate 232 can also be a straight plate or an arc plate, as long as it can be adapted to the shape of the tray 700.

[0084] refer to Figure 1 , Figure 2 and Figure 4 In the two bearing assemblies 230 that are opposite each other in the first horizontal direction X, the height of the upright plate 232 of one is greater than the height of the upright plate 232 of the other. That is, the height of the upright plate 232 in the first bearing assembly 233 is greater than the height of the upright plate 232 in the second bearing assembly 234.

[0085] By designing the upright plate 232 of the pallet assembly 230 on one side of the first horizontal direction X to be shorter and the upright plate 232 of the pallet assembly 230 on the other side of the first horizontal direction X to be taller, it is easier for workers to move the pallet assembly 710 from the lower upright plate 232 to between the two conveying assemblies 210 in the first horizontal direction X, and then place it into the pallet assemblies 230 on both sides.

[0086] Optionally, the lifting drive assembly 310 includes a lifting drive motor 311 and a lifting transmission assembly 312. The lifting drive motor 311 is fixed to the frame 100 and connected to the lifting transmission assembly 312. The lifting transmission assembly 312 is connected to the lifting member 320 and is used to convert the torque of the lifting drive motor 311 into a linear driving force that causes the lifting member 320 to rise and fall.

[0087] In this way, the lifting drive motor 311 provides stable torque, and the lifting transmission assembly 312 converts the torque into linear driving force to drive the lifting component 320 to move up and down smoothly. Moreover, the lifting transmission assembly 312 can also amplify the power, reduce the load on the lifting drive motor 311, and extend its service life.

[0088] Among them, the lifting transmission assembly 312 can adopt transmission components such as gear rack pairs, ball screw pairs, etc., which can convert torque into linear driving force.

[0089] In order to realize the installation of the lifting mechanism 300, a lifting mounting frame 120 is provided on the frame 100. The lifting transmission assembly 312 and the lifting drive motor 311 are both provided on the lifting mounting frame 120. The lifting component 320 is slidably provided on the lifting mounting frame 120 so as to be lifted and lowered under the drive of the lifting drive motor 311.

[0090] Of course, in some embodiments, the lifting drive assembly 310 may also be a power component such as a hydraulic cylinder that can directly provide linear driving force, as long as it can control the lifting component 320 to lift the tray 700 to a preset height each time.

[0091] refer to Figure 1 , Figure 2 and Figure 5 In this embodiment, the feeding device further includes a clamping mechanism 400, which is fixed on the frame 100. The clamping mechanism 400 is used to clamp or release the tray 700 when there is only one tray 700 left on the tray assembly 230.

[0092] Thus, the clamping mechanism 400 clamps the last pallet 700, so that while the downstream equipment removes the pallet 700, the lifting component 320 can be lowered by the lifting drive component 310, so that the next batch of pallet groups 710 can reach the lifting station under the conveying action of the conveying component 210 and be located above the lifting component 320. After the downstream equipment removes the last pallet 700 of the previous batch, the lifting component 320 can then lift the next batch of pallet groups 710, so as to continuously provide pallets 700 for subsequent downstream equipment.

[0093] For more details, please refer to the following: Figure 5 The clamping mechanism 400 includes two pushers 410 arranged along a first horizontal direction X. The two pushers 410 are located on the side of the two conveying components 210 that are far apart from each other. The two pushers 410 can move closer to each other or further apart to clamp or release the tray 700 together.

[0094] By arranging two pushers 410 along the first horizontal direction X and respectively located on the side of the two conveying components 210 that are far apart from each other, the two pushers 410 can clamp the tray 700 when they are close to each other and can release the tray 700 when they are far apart, so that the downstream equipment can take it away.

[0095] refer to Figure 6 and Figure 7The clamping mechanism 400 also includes two support members 420 located on opposite sides of the two conveying assemblies 210; the pushing member 410 includes a tray 411 and a driving member 412, with the tray 411 facing each other in the two pushing members 410, and the driving member 412 fixed on the support member 420 and connected to the tray 411, and the driving member 412 is used to drive the tray 411 to move along the first horizontal direction X.

[0096] By using the support member 420 for the installation of the push member 410, the entire push member 410 can be raised to match the height when the lifting member 320 lifts the last pallet 700. When the drive member 412 drives the pallet 411 to move along the first horizontal direction X, the distance between the two push members 410 can be shortened or lengthened, thereby achieving the effect of clamping or releasing the pallet 700.

[0097] In detail, the support member 420 includes a base column 421 and a support platform 422 connected to the top of the base column 421. The bottom end of the base column 421 is connected to the frame 100. The pusher 410 is installed on the support platform 422 to raise the pusher 410.

[0098] Continue to refer to Figures 5-7 The feeding device also includes a detection element 500, which is disposed on the clamping mechanism 400. When the detection element 500 detects that there is only one tray 700 left, the clamping mechanism 400 can clamp the tray 700.

[0099] In this embodiment, a detection element 500 is used to identify whether there is only one pallet 700 left on the lifting element 320. When it is identified that there is only one pallet 700 left, the clamping mechanism 400 clamps the pallet 700, so that the lifting element 320 can descend to receive the next batch of pallet group 710.

[0100] The detection component 500 can be a photoelectric sensor, a Hall sensor, or other proximity switch. Taking the photoelectric sensor as an example, its setting height should be lower than the height of the tray 700 when it is taken away by the downstream equipment. In this way, when there are multiple trays in the tray group 710, the photoelectric sensor is blocked by the tray 700. However, when there is only one tray 700 left, the height of the tray 700 should be higher than the photoelectric sensor, so the photoelectric sensor is not blocked. The light spot sensor sends a pulse signal accordingly, and the pushing component 410 can operate. The two driving components 412 drive the connecting plate 411 to move closer to each other to clamp the last tray 700.

[0101] In summary, this application discloses a feeding device that allows workers to stack multiple pallets 700 into a pallet group 710 and then move them onto the pallet support assembly 230 in one go, reducing labor intensity and saving time and effort.
