Description

Technical Field

[0001] The present application relates to the field of pharmaceutical equipment, and in particular to a desiccant dispenser. Background Art

[0002] A desiccant dispenser is a device that uses automated mechanical control to package desiccant into designated bags or place it in a specific location. It is primarily used to ensure the dryness and quality of items. In the pharmaceutical industry, desiccant placement is crucial for ensuring drug quality and extending shelf life.

[0003] The desiccant dispenser mainly includes a feeding system, a metering system, a dispensing system, a control system and a detection system. The feeding system is responsible for transporting the desiccant from the storage container to the metering and dispensing system; the metering system includes a metering device and an adjustment mechanism. The metering device is responsible for accurately measuring the amount of desiccant dispensed each time, and the adjustment mechanism is responsible for adjusting the dispensing amount and dispensing speed to meet the needs of different products or production lines; the dispensing system includes a dispensing port and a guide mechanism. The dispensing port is used to dispense the desiccant into the packaging bag or bottle through this port, and the guide mechanism is used to guide the desiccant into the dispensing port to ensure a smooth and unobstructed process; the control system plays an important role in intelligent management to adapt to different application scenarios.

[0004] There are many different types of desiccant dispensing equipment available in the related art. Bottles are transported at regular intervals on a conveyor belt. When bottles are transported to the dispensing port for desiccant delivery, some may be missed. A detection system is responsible for detecting missed desiccant delivery, and bottles that miss desiccant delivery are considered unqualified. To reject unqualified bottles, the detection system of the related art desiccant dispenser requires an operator to collect them in a recycling bin and then re-place them at the dispensing port for desiccant delivery. This is labor-intensive for the operator. Utility Model Content

[0005] In order to solve the problem in the related art that the detection system of the desiccant dispenser can only detect and collect the unqualified packaging bottles after rejecting them, and the subsequent work still requires manual intervention to re-add the unqualified packaging bottles, which increases labor intensity, the present application provides a desiccant dispenser.

[0006] The present application provides a desiccant dispenser, which adopts the following technical solution:

[0007] A desiccant dispenser includes a feeding mechanism, a first conveyor belt arranged below the feeding mechanism for transmitting packaged bottles, a belt scale arranged at the unloading end of the first conveyor belt, a first controller electrically connected to the belt scale, a second conveyor belt for transmitting unqualified packaged bottles, a third conveyor belt for transmitting qualified packaged bottles, a first pushing component arranged above the belt scale for moving unqualified packaged bottles to the second conveyor belt, the first pushing component being electrically connected to the first controller; a photoelectric sensor arranged on the second conveyor belt, a second controller electrically connected to the photoelectric sensor, a second pushing component arranged above the second conveyor belt for moving unqualified packaged bottles to the loading end of the first conveyor belt, the second pushing component being electrically connected to the second controller.

[0008] By adopting this technical solution, compared to related art desiccant dispensers whose detection systems only detect unqualified bottles, collecting them in a collection bin and awaiting manual re-delivery, the unqualified bottles are moved to a belt scale, which measures their mass. For unqualified bottles, a first controller issues a command, instructing the first pusher assembly to push them onto a second conveyor belt. The second conveyor belt transports the unqualified bottles toward the loading end of the first conveyor belt. When the unqualified bottles reach the photoelectric sensor area, the second controller issues a command, instructing the second pusher assembly to push them from the second conveyor belt to the loading end of the first conveyor belt. The unqualified bottles are then transported by the first conveyor belt to the bottom of the feeding mechanism for re-delivery of desiccant. This entire process allows unqualified bottles to be re-delivered with desiccant without manual intervention, reducing operator workload. Furthermore, the belt scale ensures that unqualified bottles are detected for missed desiccant doses while also ensuring the proper delivery of qualified bottles.

[0009] Optionally, the first pushing assembly includes a first push plate arranged on the side of the belt scale away from the second conveyor belt and a first telescopic driving member for pushing the first push plate, and the first telescopic driving member is electrically connected to the first controller.

[0010] By adopting the above technical solution, when the belt scale identifies an unqualified packaged bottle whose weight does not meet the standard, the first controller issues an instruction to activate the first telescopic drive member. The first push plate contacts the unqualified packaged bottle under the driving action of the first telescopic drive member, and applies a horizontal force to the bottle body of the packaged bottle to ensure that the packaged bottle slides horizontally from the belt scale to the second conveyor belt. The first push plate and the first telescopic drive member enable the packaged bottle to reach the second conveyor belt by only moving in the horizontal direction.

[0011] Optionally, a guide member is provided on a side of the first push plate away from the first telescopic driving member, and the guide member fits the shape of the bottle body of the packaging bottle.

[0012] By adopting the above technical solution, the shape of the guide member fits the shape of the bottle body of the packaging bottle, and can adapt to packaging bottles with different bottle body shapes. During the pushing process of the first push plate, the bottle body of the packaging bottle is evenly stressed, ensuring the smooth sliding of the packaging bottle. At the same time, the shape of the guide member plays a certain guiding role in the sliding direction of the packaging bottle, ensuring that the packaging bottle can slide along the direction pushed by the first push plate.

[0013] Optionally, a buffer member is provided between the first push plate and the guide member to buffer the guide member.

[0014] By adopting the above technical solution, when the first push plate drives the guide member to contact the bottle body of the packaging bottle under the driving action of the first telescopic driving member, the buffer member alleviates the vibration and impact generated by the packaging bottle when it is pushed by the guide member to a certain extent, ensuring that the packaging bottle can slide smoothly under the pushing action of the first pushing component.

[0015] Optionally, the second pushing assembly includes a second push plate provided on a side of the second conveyor belt away from the first conveyor belt and a second telescopic driving member for pushing the second push plate, and the second telescopic driving member is electrically connected to the second controller.

[0016] By adopting the above technical solution, when the photoelectric sensor identifies an unqualified packaging bottle, the second controller issues an instruction to activate the second telescopic drive member. The second push plate contacts the unqualified packaging bottle under the driving action of the second telescopic drive member and applies a horizontal force to the bottle body of the packaging bottle to ensure that the packaging bottle slides horizontally from the second conveyor belt to the feeding end of the first conveyor belt. The second push plate and the second telescopic drive member enable the packaging bottle to move only in the horizontal direction and then return to the first conveyor belt.

[0017] Optionally, a first limit plate and a third telescopic drive component for extending and retracting the first limit plate are provided between the belt scale and the first conveyor belt. The third telescopic drive component is electrically connected to the first controller. When the belt scale detects unqualified packaging bottles, the first limit plate limits the packaging bottles to be inspected.

[0018] With this technical solution, when the belt scale identifies an unqualified bottle that does not meet the weight standard, the first controller issues a command to activate the third telescopic drive member, which then extends the first limit plate, limiting the position of the bottles to be inspected behind the currently detected unqualified bottle. The first limit plate prevents the bottles to be inspected behind the unqualified bottle from being pushed onto the second conveyor belt by the first push assembly. After the first push plate retracts, the first limit plate, driven by the third telescopic drive member, retracts, ensuring normal inspection and conveyance of the bottles to be inspected behind.

[0019] Optionally, the loading end of the first conveyor belt is provided with a second limit plate and a fourth telescopic drive component for extending and retracting the second limit plate. The fourth telescopic drive component is electrically connected to the second controller. When the photoelectric sensor identifies the packaging bottle, the second limit plate limits the packaging bottle without desiccant.

[0020] By adopting the above technical solution, when the photoelectric sensor identifies a packaging bottle, the second controller issues an instruction to activate the fourth telescopic drive member, and the fourth telescopic drive member drives the second limit plate to extend, thereby limiting the packaging bottles behind the packaging bottles pushed by the second pushing component on the first conveyor belt. The packaging bottles behind the packaging bottles pushed by the second pushing component are packaging bottles without desiccant. The second limit plate prevents the packaging bottles without desiccant from being affected by the second pushing component. After the second push plate retracts, the second limit plate retracts under the drive of the fourth telescopic drive member, ensuring that the packaging bottles without desiccant at the rear can be normally transported and desiccant can be added.

[0021] Optionally, a first baffle is provided on a side of the second conveyor belt away from the first conveyor belt to block unqualified packaging bottles pushed by the first pushing assembly.

[0022] By adopting the above technical solution, unqualified packaging bottles will be subjected to a force in a pushing direction when pushed by the first pushing component. In order to prevent the packaging bottles from being pushed out of the second conveyor belt, the first baffle plays a certain blocking role on the pushed packaging bottles, thereby preventing the packaging bottles from falling from the second conveyor belt.

[0023] Optionally, a second baffle is provided on the second conveyor belt for isolating unqualified packaging bottles conveyed by the second conveyor belt.

[0024] By adopting the above technical solution, unqualified packaging bottles are transported to the position of the second pushing assembly under the transmission of the second conveyor belt, and the second baffle plays a certain blocking role on the packaging bottles transmitted to the second pushing assembly, preventing the packaging bottles from falling from the second conveyor belt.

[0025] Optionally, a buffer platform is provided between the first conveyor belt and the second conveyor belt to slow down the sliding speed of the first pushing assembly and the second pushing assembly in pushing unqualified packaging bottles.

[0026] By adopting the above technical solution, when unqualified bottles are moved from the belt scale to the second conveyor belt, the belt scale and the second conveyor belt move in opposite directions, resulting in a speed difference between the first conveyor belt and the second conveyor belt. This speed difference may cause the bottles to fall during movement. Similarly, when unqualified bottles are moved from the second conveyor belt to the first conveyor belt, they may also fall due to the speed difference. By providing a buffer table, when unqualified bottles pass from the belt scale to the second conveyor belt, the speed difference between the belt scale and the buffer table is minimized, and the speed difference between the buffer table and the second conveyor belt is minimized, thus ensuring the stability of the movement of unqualified bottles. Similarly, when unqualified bottles are moved from the second conveyor belt to the first conveyor belt, the buffer table also reduces the speed difference, thus ensuring the stability of the movement of unqualified bottles.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. Compared to desiccant dispensers in related technologies that only detect unqualified bottles but still require an operator to refill them, the belt scale in this application identifies unqualified bottles. A first controller issues a command to cause a first push assembly to move the unqualified bottles from the belt scale to a second conveyor belt. A photoelectric sensor then identifies the bottles, causing a second controller to issue a command to cause a second push assembly to move the unqualified bottles from the second conveyor belt to the first conveyor belt. The second conveyor belt transports the unqualified bottles from a position near the unloading end of the first conveyor belt to a position near the loading end of the first conveyor belt. This entire process allows unqualified bottles to be refilled with desiccant without human intervention.

[0029] 2. The setting of the belt scale not only ensures the detection of whether the desiccant is omitted in the packaging bottles, but also ensures that the qualified packaging bottles can be transported normally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Reference Figure 1 The present application discloses a desiccant dispenser, comprising a feeding mechanism 1 fixedly mounted on the ground via a bracket, and a first conveyor belt 2 disposed below the feeding mechanism 1, with the feeding mechanism 1 located in the middle of the first conveyor belt 2. The first conveyor belt 2 is used to transport desiccant bottles, and the loading end of the first conveyor belt 2 is used to receive bottles that have not been loaded with desiccant. The first conveyor belt 2 is fixedly mounted on the ground, and a belt scale 3 of the same width as the first conveyor belt 2 is aligned with the unloading end of the first conveyor belt 2. A third conveyor belt 6 for transporting qualified bottles is aligned with the end of the belt scale 3 away from the first conveyor belt 2. The belt scale 3 and the third conveyor belt 6 are each fixedly mounted on the ground.

[0038] A second conveyor belt 5 is installed on one side of the first conveyor belt 2. The conveyor belt 5 runs in the opposite direction of the first conveyor belt 2 and is used to transport unqualified bottles. The second conveyor belt 5 is fixed to the ground, with one end extending to the loading end of the first conveyor belt 2 and the other end extending to the unloading end of the first conveyor belt 2. The upper surface of the second conveyor belt 5 is flush with the upper surface of the first conveyor belt 2.

[0039] Reference Figure 2 and Figure 3A desiccant dispenser also includes a first push assembly 7 disposed above a belt scale 3 and a first controller 4 electrically connected to the belt scale 3. The first controller 4 is fixedly mounted on a side of the third conveyor belt 6 near the first push assembly 7. The first push assembly 7 pushes unqualified bottles onto the second conveyor belt 5. The first push assembly 7 includes a first push plate 71 disposed on a side of the belt scale 3 away from the second conveyor belt 5 and a first telescopic drive member 72 for pushing the first push plate 71. The first telescopic drive member 72 is a pneumatic cylinder fixed to the ground via a bracket. The first telescopic drive member 72 is electrically connected to the first controller 4.

[0040] A guide member 73 is mounted on the side of the first push plate 71 facing away from the first telescopic drive member 72. A buffer member 74 is disposed between the first push plate 71 and the guide member 73 to cushion the guide member 73. The buffer member 74 is made of rubber, but is not limited to rubber; other elastic materials may also be used. Under the action of the first push plate 71, the guide member 73 contacts the bottle, and the side of the guide member 73 facing away from the first push plate 71 conforms to the shape of the bottle. In this embodiment, the side of the guide member 73 facing away from the first push plate 71 is arc-shaped. It should be noted that the shape of the guide member 73 is not limited to a single shape and can vary depending on the shape of the bottle.

[0041] When the guide member 73 contacts the bottle under the action of the first push plate 71, the elasticity of rubber absorbs the vibration and impact generated by the guide member 73 pushing the bottle, which is then absorbed by the buffer member 74. This ensures that the bottle slides smoothly under the push of the first push plate 71. At the same time, the guide member 73 conforms to the shape of the bottle, ensuring that the force applied to the bottle by the first push plate 71 is evenly distributed, ensuring smooth sliding of the bottle from the belt scale 3 to the second conveyor belt 5.

[0042] Reference Figure 2 and Figure 4 A desiccant dispenser also includes a second pushing assembly 10 mounted on the ground, a photoelectric sensor 8 fixedly mounted on the second conveyor belt 5, and a second controller 9 electrically connected to the photoelectric sensor 8. The second controller 9 is fixedly mounted on the side of the second conveyor belt 5 close to the second pushing assembly 10. The second pushing assembly 10 moves unqualified packaging bottles to the loading end of the first conveyor belt 2. The second pushing assembly 10 includes a second push plate 101 disposed on the side of the second conveyor belt 5 away from the first conveyor belt 2 and a second telescopic drive member 102 for pushing the second push plate 101. The second telescopic drive member 102 is a cylinder fixedly mounted on the ground via a bracket. The second telescopic drive member 102 is electrically connected to the second controller 9.

[0043] Photoelectric sensors 8 are fixedly mounted on both sides of the second conveyor belt 5, located on the side of the second pusher assembly 10 near the unloading end of the first conveyor belt 2. Photoelectric sensors 8 include a receiving end mounted on one side of the second conveyor belt 5 and a transmitting end mounted on the other side of the second conveyor belt 5. The transmitting end is a light-emitting diode that emits a light beam, and the receiving end is a photosensor that detects the light beam emitted by the transmitting end. Photoelectric sensors 8 detect bottles by detecting the light beam emitted by the transmitting end when the bottle blocks the light beam.

[0044] Replay Figure 1 A buffer platform a is provided between the first conveyor belt 2 and the second conveyor belt 5. The buffer platform a is a metal plate flush with the height of the first and second conveyor belts 2 and 5. One end of the buffer platform a extends to the end of the belt scale 3 away from the first conveyor belt 2, and the other end of the buffer platform a extends to the loading end of the first conveyor belt 2. When the first pusher assembly 7 pushes an unqualified bottle, the unqualified bottle slides from the belt scale 3 to the second conveyor belt 5 via the buffer platform a. When the second pusher assembly 10 pushes an unqualified bottle, the unqualified bottle slides from the second conveyor belt 5 to the first conveyor belt 2 via the buffer platform a. The provision of the buffer platform a minimizes the speed difference between the belt scale 3 and the buffer platform a, minimizes the speed difference between the buffer platform a and the second conveyor belt 5, and minimizes the speed difference between the buffer platform a and the first conveyor belt 2, thereby ensuring the stability of the movement of unqualified bottles.

[0045] A first baffle 51 is fixedly mounted on the side of the second conveyor belt 5 away from the first conveyor belt 2. The first baffle 51 blocks unqualified bottles pushed by the first pusher assembly 7. The first baffle 51 is aligned with the first pusher assembly 7. When bottles are moved from the belt scale 3 to the second conveyor belt 5 by the first pusher assembly 7, they may fall off the second conveyor belt 5 due to inertia. The first baffle 51 prevents the bottles from falling off the second conveyor belt 5.

[0046] The second conveyor belt 5 is provided with a second baffle 52 to block unqualified bottles being transported along the second conveyor belt 5. The second baffle 52 is fixedly mounted at the end of the second conveyor belt 5 in its conveying direction. When bottles reach the end of the second conveyor belt 5 after being transported by the second conveyor belt 5, they may fall off the second conveyor belt 5 due to inertia. The second baffle 52 prevents the bottles from falling off the second conveyor belt 5.

[0047] A third baffle 25 is fixedly mounted on the side of the first conveyor belt 2 away from the second conveyor belt 5. This baffle 25 blocks unqualified bottles pushed by the second pusher assembly 10. The third baffle 25 is aligned with the second pusher assembly 10. When bottles are pushed from the second conveyor belt 5 to the first conveyor belt 2 by the second pusher assembly 10, they may fall off the first conveyor belt 2 due to inertia. However, the third baffle 25 prevents these bottles from falling off the first conveyor belt 2.

[0048] Reference Figure 5 A first limit plate 21 and a third telescopic driving component 22 for controlling the extension and retraction of the first limit plate 21 are arranged between the belt scale 3 and the first conveyor belt 2. The third telescopic driving component 22 is a cylinder, which is fixedly mounted on the ground through a bracket. The third telescopic driving component 22 is electrically connected to the first controller 4.

[0049] When the belt scale 3 identifies an unqualified packaging bottle, the first controller 4 issues an instruction to activate the third telescopic drive member 22, and the third telescopic drive member 22 drives the first limit plate 21 to extend, and the first limit plate 21 limits the packaging bottle to be inspected; when the first push plate 71 of the first pushing assembly 7 retracts, the first controller 4 issues an instruction to activate the third telescopic drive member 22 to drive the first limit plate 21 to retract.

[0050] The loading end of the first conveyor belt 2 is provided with a second limit plate 23 and a fourth telescopic driving component 24 for controlling the extension and retraction of the second limit plate 23. The fourth telescopic driving component 24 is a cylinder, which is fixedly mounted on the ground through a bracket. The fourth telescopic driving component 24 is electrically connected to the second controller 9.

[0051] When the photoelectric sensor 8 identifies a packaging bottle, the second controller 9 issues a command to activate the fourth telescopic drive member 24, which drives the second limit plate 23 to extend, and the second limit plate 23 limits the packaging bottle without desiccant; when the second push plate 101 of the second pushing assembly 10 retracts, the second controller 9 issues a command to cause the fourth telescopic drive member 24 to drive the second limit plate 23 to retract.

[0052] The implementation principle of a desiccant dispenser in the embodiment of the present application is as follows:

[0053] Before the desiccant dispenser is activated, a weighing threshold X is set for belt scale 3. This threshold X represents the weight of the bottles after desiccant is dispensed. The desiccant dispenser is then activated, and belt scale 3 weighs the bottles to be inspected, obtaining a weight Y. As desiccant is dispensed through feeding mechanism 1, some bottles may miss the desiccant.

[0054] When Y < X, it is identified as a non-conforming packaging bottle. The first controller 4 issues an instruction to make the first telescopic driving member 72 act. The first telescopic driving member 72 drives the first push plate 71 to push the non-conforming packaging bottle. Under the pushing action of the first push plate 71, the non-conforming packaging bottle reaches the second conveyor belt 5 from the belt scale 3 via the buffer table a. The non-conforming packaging bottle moves in the direction of the feeding end of the first conveyor belt 2 closer to the second conveyor belt 5 under the conveyance of the second conveyor belt 5. When the photoelectric sensors 8 on both sides of the second conveyor belt 5 identify the packaging bottle, it means that the packaging bottle is transported to the position of the second conveyor belt 5 close to the second pushing component 10. The second controller 9 issues an instruction to make the second telescopic driving member 102 act. The second telescopic driving member 102 drives the second push plate 101 to push the non-conforming packaging bottle. Under the pushing action of the second push plate 101, the non-conforming packaging bottle reaches the feeding end of the first conveyor belt 2 from the second conveyor belt 5 via the buffer table a. The non-conforming packaging bottle is fed again through the feeding mechanism 1 under the conveyance of the first conveyor belt 2.

[0055] When Y = X, it is identified as a conforming packaging bottle. The conforming packaging bottle is continuously conveyed by the belt scale 3 to the third conveyor belt 6 for the next process.

[0056] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
