Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical conveying technology, and in particular to a material handling mechanism for an anti-clogging conveyor belt. Background Technology

[0002] like Figure 7 The image shows a common form of pharmaceutical packaging. During the production and packaging process, light inspection and other corresponding testing procedures are often required. However, due to the high speed of the conveyor belt, the efficiency of light inspection cannot meet the needs of the conveyor speed. Therefore, it is necessary to split the conveyor belt in two so that the finished drugs can enter two light inspection lines for testing. Therefore, a reversing mechanism needs to be set on the conveyor belt to evenly distribute the drugs into the two light inspection lines.

[0003] In existing technologies, the track-separating material handling mechanism only has one proximity switch and a corresponding support, such as Figure 6 As shown, its position is usually installed at the first crossbar; since it is fixed on the swing arm of the reversing assembly, the whole thing moves with the swing arm; the proximity switch is affected by the vibration of the swing arm movement for a long time, which leads to insensitive detection, false detection or even no detection, and ultimately causes excessive medicine to flood into a certain light inspection line, causing medicine jamming; medicine jamming occurs every 5-10 minutes, the frequency of medicine jamming is too frequent, and manual troubleshooting is required to eliminate the fault, which affects production efficiency.

[0018] like Figure 1-2As shown, the present invention proposes an anti-clogging conveyor belt material handling mechanism, which includes a reversing component 2 and a triggering component 6 installed on the conveyor belt 1; The reversing component 2 controls the feeding direction through the pushing component 5, so that the medicine plate 4 switches directions between the first mesh belt 11 and the second mesh belt 12; The triggering component 6 is mounted at the end of the reversing component 2 via the support component 3; the triggering component 6 includes at least two proximity sensors 62; the at least two proximity sensors 62 form a complementary dual detection structure at the end of the reversing component 2; when the medicine plate 4 passes over the first mesh belt 11 or the second mesh belt 12, both proximity sensors 62 will receive detection signals; the reversing component 2 is controlled to move according to the detection signals to prevent the medicine plate 4 from accumulating on a certain mesh belt.

[0019] In this embodiment, as Figure 1 As shown, the conveyor belt 1 includes a first mesh belt 11 and a second mesh belt 12; The incoming conveyor belt extends to the second conveyor belt 12; the first conveyor belt 11 is arranged parallel to one side of the second conveyor belt 12; the reversing assembly 3 is installed on the parallel section of the first and second conveyor belts; the reversing assembly 3 switches the direction, guiding the medicine plate 4 to the first conveyor belt 11 or the second conveyor belt 12. Figure 2 As shown, the reversing assembly 2 includes two parallel movable plates 22 and a connecting shaft 21 adapted to the movable plates 22; the parallel movable plates 22 are provided with columns and a first crossbar 23; when the pushing assembly 5 pushes the outer movable plate 22, the movable plate 22 rotates relative to the connecting shaft 21, and at the same time, the inner movable plate 22 rotates synchronously relative to its corresponding connecting shaft 21 through the connection of the first crossbar 23. The connecting shafts 21 located on the outer and inner sides are staggered, and the ends of the movable plates 22 located on the outer and inner sides are flush with each other away from the connecting shafts 21. Since the two sets of connecting shafts 21 are staggered, under the connection of the first crossbar 23, when the outer movable plate 22 rotates relative to its matching connecting shaft 21, the inner movable plate 22 rotates synchronously relative to its matching connecting shaft 21, and the two movable plates 22 always remain parallel during rotation.

[0020] In this embodiment, as a preferred solution, such as Figure 1As shown, at least one guide groove is provided on the outer movable plate 22; the output end of the pushing assembly 5 is provided with a connecting block that slides back and forth along the guide groove. The pushing assembly 5 is fixed to the outer side of the conveyor belt 1 by the support assembly 3; the pushing assembly 5 can be a linear motor, hydraulic cylinder, pneumatic cylinder or other drive that can maintain linear motion; specifically, the pushing assembly 5 includes a drive component that moves linearly and a shaft that is rotatably connected to the connecting block; a pin is provided on the upper surface of the connecting block, and the shaft is fitted on the pin and rotates with the pin; a matching limiter is provided on the shaft to limit the movement of the shaft relative to the pin in the Z-axis direction; When the output end of the drive unit extends outward, the output end presses against the pin, and due to the setting of the limiter, the shaft part rotates relative to the pin under the action of force; correspondingly, the connecting block moves along the guide groove; when the drive unit is reset, the direction of movement is completely opposite. Through the action of the drive unit, the reversing assembly 2 can switch between the first mesh belt 11 and the second mesh belt 12, so that the medicine plate 4 enters different lamp inspection lines.

[0021] like Figure 3 As shown, the trigger component 6 cooperates with the support components 3 located on both sides of the first mesh belt 11 and the second mesh belt 12 to form a mounting surface, and a second crossbar 61 is set across the first mesh belt 11 and the second mesh belt 12; two sets of proximity sensors 62 are fixed on the first crossbar 61, and the signal acquisition ends of the two sets of proximity sensors 62 correspond to the first mesh belt 11 and the second mesh belt 12 respectively. A round rod is set on the support component 3, spanning the first mesh belt 11 and the second mesh belt 12; the round rod is located below the second crossbar 61; two sets of symmetrical limiting grooves are set on the round rod, and guide rods 63 are installed in the limiting grooves; one end of the guide rod 63 is annular and fits in the limiting groove, and the other end is straight and curves upward; the straight section extends to the mesh belt and contacts the mesh belt surface; the guide rods 63 on both sides are connected by a connecting rod 64; the guide rods 63 form a linkage structure through the connecting rod 64.

[0022] When a medicine plate 4 passes through either the first mesh belt 11 or the second mesh belt 12, the guide rod 63 in the corresponding channel will be lifted. Since the other guide rod 63 is connected by the connecting rod 64, the other guide rod 63 will also be lifted. Furthermore, the signal acquisition end of the proximity sensor 62 is directly opposite the connection between the connecting rod 64 and the guide rod 63. The connecting rod 64 and the guide rod 63 are metal parts; therefore, both proximity sensors 62 will acquire proximity signals. Because the proximity sensor 62 is installed at the end of the reversing assembly via the support component 3 and does not move with the swing arm, false detections caused by mechanical vibration are greatly reduced. In addition, the two proximity sensors 62 form a dual detection effect, improving detection accuracy and reducing the possibility of medicine jamming. Example 2

[0023] like Figure 4As shown, unlike Embodiment 1, a connector 65 is provided in the middle of the connecting rod 64; the middle of the connector 65 forms a horn-shaped cavity 651; a movable shaft 642 is provided on one side of the cavity 651; a retaining plate 641 is provided on both ends of the connecting rod 64 to insert into the cavity 651, and one end of the retaining plate 641 is fitted onto the movable shaft 642; the retaining plate 641 moves inside the cavity 651; when the connecting rod 64 contacts the surface of the mesh belt, the retaining plate 641 is located at the first position in the middle of the cavity 651.

[0024] In this embodiment, for ease of understanding, the guide rod 63 corresponding to the first mesh belt 11 is designated as the first guide rod, and the guide rod 63 corresponding to the second mesh belt 12 is designated as the second guide rod; both the first and second guide rods are engaged into the connector 65 via the clamping plate 641 and the movable shaft 642; the two linkages 64 in Embodiment 1 are optimized into cooperative motion; such as Figure 4 As shown, in the initial state, when the connecting rod 64 contacts the surface of the mesh belt, the clamping plate 641 is located at the first position in the middle of the cavity 651. When a medicine plate 4 passes through the first mesh belt 11, the first guide rod moves upward first, moving to the second position above the cavity 651. At this time, the clamping plate 641 of the second guide rod is still located at the first position. As the first guide rod continues to move, the position of the clamping plate 641 on the second guide rod gradually moves to the third position (the position below the cavity 651). At this time, the second guide rod moves after a certain delay relative to the first guide rod, so that there is a time difference in the proximity signals obtained by the two proximity sensors 62. This helps to determine which mesh belt has the medicine plate 4 passing through. Furthermore, by combining the duration of the proximity signal, the number of medicine plates 4 entering the two mesh belts can be determined, and the direction can be dynamically reversed so that the number of medicine plates 4 entering the two light inspection lines is approximately the same, reducing the probability of medicine plate 4 accumulation and improving production efficiency. In this embodiment, to ensure that the clamping plate 641 is located at the first position in the middle of the cavity 651 when the connecting rod 64 contacts the surface of the conveyor belt in the initial state, a damping structure such as a torsion spring can be provided on the movable shaft 642. This embodiment simplifies the power supply and signal lines of the proximity sensor, and also simplifies the support structure of the conveyor belt 1.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
