Abstract
Description
Technical Field
[0001] This invention relates to the field of sensor detection technology, specifically to a sensor detection device for a throat lozenge pillow pack. Background Technology
[0002] The sensor detection device for throat lozenge pillow packs is a specialized piece of equipment used in automated production lines to monitor and inspect the quality of throat lozenge pillow packs. By integrating multiple sensors and a control system, it monitors parameters such as pack integrity, sealing, dimensions, weight, and foreign objects in real time, ensuring that products meet production standards and sorting or issuing alarms for non-conforming products.
[0003] During the testing of throat lozenge pillow packs, the packing process is continuous and automated. However, to assess the quality of the throat lozenge pillow packs, random sampling is usually conducted to check their integrity and airtightness. In this routine sampling process, staff need to periodically and quantitatively select a portion of the throat lozenges from the pillow packs. However, this sampling requires placing the lozenges separately into the testing instrument, not at the location of the pillow pack, making it impossible to adjust the pillow pack quality promptly based on the sampling results. Furthermore, the low frequency of pillow pack sampling makes it difficult to detect the pillow pack quality in real time.
[0004] To address these issues, existing technologies typically employ a combination of blowing and sampling. By adding a blowing device to the end of the pack, empty throat lozenges are blown away by the air as they pass through the device, preventing them from getting mixed in with the lozenges and thus affecting the yield. However, throat lozenges are small and irregular or spherical, which can cause incomplete airtightness during packing, while their overall mass remains unchanged, making them difficult to blow away and thus affecting the yield.
[0005] Therefore, in order to solve the problem that the small size of throat lozenges makes it difficult to detect their low airtightness during the pillow-packing process, thus affecting the yield of throat lozenges, this invention designs a sensor detection device for throat lozenge pillow-packs. Summary of the Invention
[0006] The present invention provides a sensor detection device for throat lozenge pillow packs, which solves the problem that the small size of throat lozenges makes it difficult to detect their low airtightness during the pillow packing process, thus affecting the yield of throat lozenges. By periodically and automatically detecting the throat lozenges after pillow packing, the airtightness of the throat lozenge pillow pack can be detected in real time during the pillow packing process, thereby improving the yield of throat lozenges.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] This invention provides a sensor detection device for throat lozenge pillow packs, applied on the conveyor belt of the throat lozenge pillow pack. It includes a detection disc located at the end of the conveyor belt, a placement disc mounted on the detection disc, a partition mounted on the placement disc, a piston disc mounted above the partition, an adjustment mechanism mounted on the piston disc, and an airtightness detection device installed inside the detection disc. The adjustment mechanism periodically moves the piston disc downwards, and the airtightness detection device performs airtightness detection on the throat lozenges below the piston disc.
[0009] The piston plate moves up and down by adjusting the piston mechanism, thereby transferring the throat lozenges on the tray while simultaneously performing a seal test. This allows for the packaging of the appropriate number of throat lozenges according to individual needs, thus achieving a three-in-one workflow of packaging, testing, and transportation. This optimizes the throat lozenge pillow pack process, reduces the sampling inspection process, and improves the yield and transmission efficiency of the throat lozenge pillow packs.
[0010] Preferably, an mounting plate is installed on the outside of the placement plate and the piston plate, and a fixing plate is installed on the top of the piston plate. The mounting plate has an inlet and an outlet.
[0011] By combining the mounting plate and the fixing plate, the bottom support can be transferred to the top support, thereby improving the overall stability during transmission.
[0012] Preferably, a fixed frame is installed at the discharge port, and a gripper is mounted on the fixed frame. The gripper moves laterally periodically via an electric telescopic rod, and a collection trough is installed below the gripper. Thus, when the placement tray rotates slowly, the gripper pushes the throat lozenges downwards in sync, thereby collecting the lozenges through the collection trough.
[0013] Preferably, the adjusting mechanism includes a motor, a rotating shaft, a connecting ring, a collar, a fixed ring, a push block, a compression spring, a return spring, and a limiting mechanism. The motor is installed below the detection plate, the rotating shaft is installed at the motor output end, the connecting ring is installed on the rotating shaft and is connected to the placement plate and the piston plate respectively, the collar is installed at the center of the piston plate, and the collar is slidably connected to the connecting ring, the fixed ring is installed on the fixed plate, and the fixed ring has a threaded groove and a straight groove corresponding to the collar position, the push block is installed on the collar and corresponds to the threaded groove, the compression spring is installed between the push block and the fixed ring, a movable groove is opened above the piston plate, the return spring is installed in the movable groove and its two ends are respectively connected to the piston plate and the collar, and the limiting mechanism is installed between the collar and the connecting ring.
[0014] Under the action of the motor, the connecting ring is driven to rotate through the rotating shaft. The connecting ring rotates through the collar. The collar uses the principle of unidirectional reciprocation to move the rotating placement plate and the piston plate downward synchronously. This enables the transmission of throat lozenges while allowing for longitudinal adjustment of the position of the throat lozenges. This allows for the partitioning and arrangement of the throat lozenges, facilitating their sorting and output. It also provides space for the airtightness testing of the throat lozenges, thereby improving the convenience of throat lozenge testing.
[0015] Preferably, the limiting mechanism includes a limiting groove, a limiting spring, a limiting block, and a pressing block. The limiting groove is formed on the connecting ring, one end of the limiting spring is installed in the limiting groove, the limiting block is installed at the other end of the limiting spring, and the pressing block is installed in the connecting ring. When the limiting block moves, on the one hand, the limiting block presses the limiting spring, and on the other hand, the limiting block releases the restraint on the collar, allowing the collar to continue moving downward. When the collar moves downward, the thrust of the collar and the elasticity of the return spring itself will quickly push the placement plate and the piston plate downward, thereby instantly switching the positions of the placement plate and the piston plate at the feed inlet, thus improving the switching speed and avoiding affecting the normal transmission of the conveyor belt.
[0016] Preferably, the airtightness detection device includes an airtight hole and a retaining ring. The airtight hole is opened on the mounting plate, and the retaining ring is installed on the placement plate and located near the center of the partition.
[0017] When an airtightness test is required, an external vacuum pump is connected to the airtightness hole. As the piston disc descends, the vacuum pump is started to extract gas from the interior. The airtightness information at that location is determined by comparing the pressure change of the vacuum pump with the received information. The retaining ring is used to achieve a central seal.
[0018] Preferably, the extrusion block is semi-circular, with a sloping surface at its top, and the limiting block has a wedge-shaped surface corresponding to the position of the extrusion block. After rotating half a turn, the extrusion block releases its pressure on the limiting block, and the push block rotates to the straight groove, where it is instantly pushed upward by the compression spring, thereby driving the collar to move upward. As the collar moves upward, the return spring pulls the placement plate and piston plate upward, thus ending the airtightness test and completing one cycle.
[0019] Preferably, the limiting block is inverted J-shaped, and the bottom of the collar has a cavity groove adapted to the extrusion block.
[0020] The beneficial effects of this invention are as follows:
[0021] 1. The present invention proposes a sensor detection device for throat lozenge pillow packs. By adjusting the mechanism, the piston plate moves up and down, thereby performing sealing detection while the throat lozenges on the tray are being transported. Simultaneously, the device can pack the corresponding number of throat lozenges according to individual needs, thus realizing a three-in-one work composition of packing, detection and transportation. This optimizes the throat lozenge pillow pack process, reduces the sampling inspection process, and improves the yield and transportation efficiency of throat lozenge pillow packs.
[0022] 2. The sensor detection device for throat lozenge pillow packs proposed in this invention, under the action of a motor, drives the connecting ring to rotate through a rotating shaft. The connecting ring rotates through a collar, which uses the principle of unidirectional reciprocating to move the rotating placement plate and piston plate downward synchronously. This enables the transmission of throat lozenges while allowing for longitudinal adjustment of the position of the throat lozenges, thereby achieving zoned arrangement of the throat lozenges. This facilitates the sorting and output of the throat lozenges and also provides space for the airtightness detection of the throat lozenges, thus improving the convenience of throat lozenge detection.
[0023] 3. The sensor detection device for throat lozenge pillow packs proposed in this invention initially engages with the collar, allowing the collar to move downward relative to the connecting ring, thereby compressing the return spring. As the connecting ring rotates, the compression block rotates with the connecting ring, and the inclined surface of the compression block contacts the wedge-shaped surface of the compression block. This causes the compression block to gradually drive the compression block to slide outward. As the compression block moves, it compresses the limiting spring while simultaneously releasing the collar, allowing it to continue moving downward. The downward movement of the collar, combined with the elasticity of the return spring, rapidly pushes the placement plate and piston plate downward, instantly switching the positions of the placement plate and piston plate at the feed inlet. This improves the switching speed and prevents interference with the normal transmission of the conveyor belt. Attached Figure Description

[0036] To better understand the above solution, the technical solution will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0037] like Figure 1-2 As shown, the present invention provides a sensor detection device for a throat lozenge pillow pack, which is applied on the conveyor belt 1 of the throat lozenge pillow pack. It includes a detection disc 2, which is located at the end of the conveyor belt 1. A placement disc 3 is installed on the detection disc 2, and a partition 4 is installed on the placement disc 3. A piston disc 5 is installed above the partition 4, and an adjustment mechanism 6 is installed at the piston disc 5. An airtightness detection device 7 is installed inside the detection disc 2. The adjustment mechanism 6 periodically drives the piston disc 5 to move downward, and the airtightness detection device 7 performs airtightness detection on the throat lozenges below the piston disc 5.
[0038] At the end of conveyor belt 1, an air pipe is added. This air pipe is connected to an external air pump to blow air in real time during the transmission process, thereby blowing air onto the throat lozenges (wrapped) on conveyor belt 1, blowing away the unwrapped candy wrappers, and thus achieving preliminary detection.
[0039] Subsequently, the throat lozenges on conveyor belt 1 enter the placement tray 3 through the feed inlet 81. It should be noted that the gap between conveyor belt 1 and feed inlet 81 should not be greater than the diameter of a throat lozenge. At the same time, in order to prevent the throat lozenges from not being able to enter feed inlet 81, certain connecting or transmission components can be added, such as a feeding plate or channel. This is conventional existing technology and will not be described in detail here.
[0040] After the throat lozenges arrive at the placement tray 3, they are separated by individual partitions 4, facilitating individual packaging and preventing mixing that would hinder subsequent packing. After the placement tray 3 rotates half a turn, the adjusting mechanism 6 moves the piston disc 5 downwards, causing half of the throat lozenges to undergo an airtightness test. An airtightness testing device 7 evacuates the bottom, sensing internal pressure changes. The reading from the internal pressure sensor is compared with the vacuum pressure reading to determine the quality and airtightness of the batch of throat lozenges. Meanwhile, the partitions 4 above the piston disc 5 continue to pack and collect the throat lozenges. After the placement tray 3 rotates one full turn, the adjusting mechanism 6 raises the placement tray 3, at which point a second partition is added between the two partitions 4 on the placement tray 3. For lozenges (set as needed, such as single-piece packaging, simply open the electric valve at the discharge port 82), the cycle is one revolution, and the usable area of the placement tray 3 is 1 / 2. If the usable area of the placement tray 3 needs to be increased, the adjustment mechanism 6 can be changed (mainly adjusting the threaded groove 651 and the extrusion block 694 on the inner fixing ring 65 of the adjustment mechanism 6, reducing the area of the extrusion block 694, and changing the projection angle of the threaded groove 651). It is necessary to ensure that the sum of the projection angle of the extrusion block 694 and the projection angle of the threaded groove 651 is equal to 360°. This allows for the use of a larger area of the placement tray 3, but the sealing test time is shorter at this time. The sealing test and packaging cycle should be adjusted according to the needs of the user.
[0041] The adjusting mechanism 6 drives the piston plate to move up and down, thereby transferring the throat lozenges on the placement tray 3 while simultaneously performing a sealing test. This allows for the packaging of the appropriate number of throat lozenges according to individual needs, thus achieving a three-in-one work process of packaging, testing, and transportation. This optimizes the throat lozenge pillow pack process, reduces the sampling inspection process, and improves the yield and transmission efficiency of the throat lozenge pillow pack.
[0042] like Figure 1-3 As shown, an installation plate 8 is installed on the outer side of the placement plate 3 and the piston plate 5, and a fixing plate 9 is installed on the top of the piston plate 5. The installation plate 8 has an inlet 81 and an outlet 82.
[0043] Mounting plate 8 provides shielding during airtightness testing and also obstructs the transmission of throat lozenges. Fixing plate 9 acts like a top cover, providing support from above and serving as a connecting component. By combining mounting plate 8 and fixing plate 9, the support from the bottom can be transferred to the top, thereby improving the overall stability during transmission.
[0044] like Figure 3 As shown, a fixing frame 10 is installed at the discharge port 82, and a gripper 11 is installed on the fixing frame 10. The gripper 11 moves laterally periodically by an electric telescopic rod, and a collection trough 12 is installed below the gripper 11.
[0045] When it is necessary to remove the throat lozenges, the grippers 11 on the fixing frame 10 (the grippers 11 are existing technology, which can be a pull rod reciprocating on an electric telescopic rod) grab the throat lozenges on the placement tray 3 and place them into the collection trough 12 for collection. During this process, the placement tray 3 can rotate or stop. When the placement tray 3 rotates, the frequency of the grippers 11 needs to be controlled to be in sync with the rotation of the placement tray 3. Thus, when the placement tray 3 rotates slowly, the grippers 11 push the throat lozenges downward in sync with the rotation, thereby collecting the throat lozenges through the collection trough 12.
[0046] like Figure 4-10 As shown, the adjustment mechanism 6 includes a motor 61, a rotating shaft 62, a connecting ring 63, a collar 64, a fixing ring 65, a push block 66, a compression spring 67, a return spring 68, and a limiting mechanism 69. The motor 61 is installed below the detection disk 2, the rotating shaft 62 is installed at the output end of the motor 61, the connecting ring 63 is installed on the rotating shaft 62 and is connected to the placement disk 3 and the piston disk 5 respectively, and the collar 64 is installed at the center of the piston disk 5. The collar 64 is slidably connected to the connecting ring 63. A fixed ring 65 is mounted on a fixed plate 9. The fixed ring 65 has a threaded groove 651 and a straight groove 652 at the position corresponding to the collar 64. The push block 66 is mounted on the collar 64 and corresponds to the threaded groove 651. The compression spring 67 is mounted between the push block 66 and the fixed ring 65. A movable groove 51 is provided above the piston plate 5. The return spring 68 is mounted in the movable groove 51 and its two ends are respectively connected to the piston plate and the collar 64. The limiting mechanism 69 is mounted between the collar 64 and the connecting ring 63.
[0047] Driven by motor 61, the rotating shaft 62 rotates. A coupling can be added between motor 61 and rotating shaft 62 to control the rotation speed of rotating shaft 62. The controller keeps motor 61 and conveyor belt 1 in sync. When rotating shaft 62 rotates, it drives connecting ring 63 to rotate, which in turn drives placement disc 3 and piston disc 5 to rotate, thus facilitating the transmission of throat lozenges. Simultaneously, the rotating ring 63 drives collar 64 to rotate. Here, connecting ring 63 and collar 64 are longitudinally slidingly connected, allowing collar 64 to drive push block 66 to rotate. A compression mechanism is connected below push block 66. The compression spring 67 is connected to the fixed ring 65 by a key, allowing the compression spring 67 to rotate relative to the fixed ring 65 (it should be noted that the compression spring 67 has a certain bending strength, so it will not deform laterally during rotation). During the rotation of the collar 64, the push block 66 rotates synchronously, and then rotates along the threaded groove 651. The threaded groove 651 is spiral downward, which will gradually squeeze the compression spring 67, causing the collar 64 to move downward as a whole, and then gradually squeeze the return spring 68 until the collar 64 is unlocked by the limiting mechanism 69, so that it continues to move downward.
[0048] Under the action of motor 61, the connecting ring 63 is driven to rotate through the rotating shaft 62. The connecting ring 63 rotates through the collar 64. The collar 64 uses the principle of unidirectional reciprocation to move the rotating placement disk 3 and the piston disk 5 downward synchronously. This enables the transmission of throat lozenges while allowing for longitudinal adjustment of the position of the throat lozenges, thus achieving the partitioned arrangement of the throat lozenges. This facilitates the sorting and output of the throat lozenges and also provides space for the airtightness testing of the throat lozenges, thereby improving the convenience of throat lozenge testing.
[0049] like Figure 4-8 As shown, the limiting mechanism 69 includes a limiting groove 691, a limiting spring 692, a limiting block 693, and a pressing block 694. The limiting groove 691 is formed on the connecting ring 63. One end of the limiting spring 692 is installed in the limiting groove 691, and the limiting block 693 is installed at the other end of the limiting spring 692. The pressing block 694 is installed in the connecting ring 63. The pressing block 694 is semi-circular, and its top has a slope 6941. The limiting block 693 has a wedge-shaped surface 6931 corresponding to the position of the pressing block 694. The limiting block 693 is inverted J-shaped, and the bottom of the collar 64 has a cavity adapted to the pressing block 694.
[0050] The limiting block 693 initially engages with the collar 64. When the collar 64 initially moves downward, it does not drive the placement plate 3 and piston plate 5 downward; it can only rotate and slide around itself. At this time, there is a certain position between the collar 64 and the limiting block 693, allowing the collar 64 to move downward relative to the connecting ring 63, thereby compressing the return spring 68. During the rotation of the connecting ring 63, the compression block 694 rotates with the connecting ring 63, and then the inclined surface 6941 of the compression block 694 contacts the wedge-shaped surface 6931 of the limiting block 693, thereby gradually driving the limiting block 693 to slide outward. The inclined surface 6941 of the extrusion block 694 is arc-shaped, that is, it is inclined from the inner circle apex to the outer circle, so as to cooperate with the wedge surface 6931 to achieve lateral movement. When the limiting block 693 moves, on the one hand, the limiting block 693 squeezes the limiting spring 692, and on the other hand, the limiting block 693 releases the restraint on the collar 64, so that the collar 64 can continue to move downward. When the collar 64 moves downward, the thrust of the collar 64 and the elasticity of the return spring 68 will push the placement plate 3 and the piston plate 5 downward rapidly, thereby instantly switching the position of the placement plate 3 and the piston plate 5 at the feed port 81, thereby improving the switching speed and avoiding affecting the normal transmission of the conveyor belt 1.
[0051] After rotating half a turn, on the one hand, the squeezing block 694 releases the squeezing of the limiting block 693, and on the other hand, the push block 66 rotates to the straight groove 652 and is instantly pushed upward by the compressed spring 67, thereby driving the collar 64 to move upward. When the collar 64 moves upward, it pulls the placement plate 3 and the piston plate 5 upward through the reset spring 68, thereby ending the airtightness test and completing one cycle.
[0052] Piston disc 5 is not a piston in the true sense, but rather refers to the good sealing performance of piston disc 5 at its edges, which enables airtightness testing.
[0053] The airtightness testing device 7 includes an airtightness hole 71 and a retaining ring 72. The airtightness hole 71 is opened on the mounting plate 8, and the retaining ring 72 is installed on the placement plate 3 and is located near the center of the partition plate 4.
[0054] When an airtightness test is required, an external vacuum pump is connected to the airtightness hole 71. As the piston disc 5 descends, the vacuum pump is started to extract gas from the interior. At this time, the reading of the internal sensor changes, and the internal pressure change is converted into an electrical signal. The airtightness information at that location is obtained by comparing the pressure change of the vacuum pump with the received information. The retaining ring 72 is used to achieve a central seal.
[0055] like Figure 1-10As shown, an air pipe is added at the end of the conveyor belt 1. The air pipe is connected to an external air pump to blow air in real time during the transmission process. Then, the throat lozenges on the conveyor belt 1 enter the placement tray 3 through the feed port 81. After the throat lozenges reach the placement tray 3, they are separated by partitions 4. After the placement tray 3 rotates half a turn, the adjusting mechanism 6 drives the piston plate 5 to move downward, thereby driving the throat lozenges to perform airtightness testing.
[0056] Specifically, driven by motor 61, the rotating shaft 62 rotates, which in turn drives the connecting ring 63 to rotate. The connecting ring 63 then drives the placement disc 3 and the piston disc 5 to rotate, thereby facilitating the transmission of the throat lozenge. As the connecting ring 63 rotates, it drives the collar 64 to rotate. During the rotation of the collar 64, the push block 66 rotates synchronously, and then rotates along the threaded groove 651. The threaded groove 651 spirals downward, which gradually compresses the compression spring 67, causing the collar 64 to move downward as a whole. This gradually compresses the return spring 68 until the collar 64 is unlocked by the limiting mechanism 69, allowing it to continue moving downward.
[0057] When the collar 64 initially moves downward, it does not cause the placement plate 3 and piston plate 5 to move downward; it can only rotate and slide around itself. At this time, there is a certain position between the collar 64 and the limiting block 693, allowing the collar 64 to move downward relative to the connecting ring 63, thereby compressing the return spring 68. During the rotation of the connecting ring 63, the compression block 694 rotates with the connecting ring 63, and then contacts the wedge-shaped surface 6931 of the limiting block 693 through the inclined surface 6941 of the compression block 694. Thus, the compression block 694 gradually drives the limiting block 693 to slide outward. When the limiting block 693 moves, on the one hand, the limiting block 693 compresses the limiting spring 692, and on the other hand... The limiting block 693 releases the restraint on the collar 64, allowing the collar 64 to continue moving downward. When the collar 64 moves downward, the thrust of the collar 64 and the elasticity of the return spring 68 will quickly push the placement plate 3 and the piston plate 5 downward, thereby instantly switching the position of the placement plate 3 and the piston plate 5 at the feed port 81. After rotating half a turn, on the one hand, the squeezing block 694 releases the squeezing of the limiting block 693, and on the other hand, the push block 66 rotates to the straight groove 652, and is instantly pushed upward by the compressed spring 67, thereby driving the collar 64 to move upward. When the collar 64 moves upward, it pulls the placement plate 3 and the piston plate 5 upward through the return spring 68, thus ending the airtightness test and completing one cycle.
[0058] The foregoing has shown and described the basic principles and beneficial effects of the present invention. However, the present invention is not limited to the above embodiments.

All such changes and modifications fall within the scope of the present invention as claimed, which is defined by the appended claims and their equivalents.
