A vibrating feeder

Abstract

This application discloses a vibrating feeder, including a guide plate with an internal slide, a roller located below the discharge port of the slide, and a guard plate located outside the roller. The outer circumference of the roller has a material receiving trough adapted to the discharge port. A bypass opening is formed at the discharge port, extending forward along the direction of roller rotation and penetrating the side wall of the slide. The outer side of the bypass opening is covered with a stop that can be opened by the thrust generated by material that has not fully entered the material receiving trough and protrudes from the trough opening, allowing the material to pass through the bypass opening. The guard plate is a thin sheet structure with multiple plates spaced apart along the axial direction of the roller. Each guard plate has an arc-shaped edge adapted to the outer circumference of the roller, and a channel is formed between any two guard plates. The arc-shaped edge and the channel are used to guide materials that have entered the material receiving trough and those that have not entered the trough to different discharge positions.

Description

Technical Field

[0001] This application relates to the technical field of feeding equipment for blister packaging machines, specifically a vibrating feeder. Background Technology

[0002] Blister packaging machines are automated devices that form PVC materials into blister packs and then feed the material into the blister packs using a feeder. Existing feeders of this type typically use a chute for material alignment and conveying. A roller with a material trough is positioned below the chute's outlet. After the material enters the trough through the chute, the roller rotates a predetermined interval until the material-filled trough is below the roller's axis and falls into the blister pack, completing one feeding cycle. To prevent material escape, the gap between the end face of the chute at the outlet and the roller surface is usually designed to be relatively small. During operation, when the material exhibits abnormal structures, such as being larger than the trough or having an abnormally shaped sheet, preventing complete entry into the trough and protruding from the trough opening, the material is crushed by the trough opening and the corresponding sidewall of the chute's outlet as the roller rotates. This results in material breakage, causing the material to fall into the blister pack below, severely impacting packaging quality and yield. Therefore, it is necessary to address these issues. Summary of the Invention

[0003] The purpose of this application is to provide a vibratory feeder to solve the problems in the prior art.

[0004] To achieve the above objectives, this application provides the following technical solution: a vibrating feeder, including a guide plate 2 with an internal slide 3, a roller 4 located below the discharge port 6 of the slide 3, and a protective plate 12 located outside the roller 4. The outer circumference of the roller 4 is provided with a material receiving groove 5 adapted to the discharge port 6. A bypass port 7 is formed at the discharge port 6, extending through the side wall of the slide 3 in front of the roller 4 along the rotation direction. The bypass port 7 is covered with a stop 8 that can be opened by the thrust generated by the movement of material that does not enter the material receiving groove 5 but protrudes from the opening surface of the material receiving groove 5, allowing the material to pass through the bypass port 7.

[0005] Furthermore, the guard plate 12 is a thin sheet structure and multiple plates are spaced apart along the axial direction of the roller 4. The guard plate 12 has an arc-shaped edge 1201 that is adapted to the outer circle of the roller 4. A channel 18 is formed between any two guard plates 12. The arc-shaped edge 1201 and the channel 18 are used to guide materials that have entered the material trough 5 and materials that have not entered the material trough 5 to different discharge positions.

[0006] Furthermore, it also includes a vibratory feeder 1, with the slide 3 inlet of the guide plate 2 connected to the output end of the vibratory feeder 1 for conveying materials output from the vibratory feeder 1 in a row.

[0007] Furthermore, one end of the stop 8 is rotatably supported by the rotating shaft 10, the free end of the stop 8 faces the roller 4 and the side wall of the free end is used to cover the bypass port 7; it also includes a force-applying member for making the side wall of the stop 8 cover the bypass port 7.

[0008] Furthermore, the force-applying component is a counterweight 9 installed on the stop 8, and the distance between the center of gravity of the counterweight 9 and the center of the rotating shaft 10 is adjustable.

[0009] Furthermore, the force-applying component is a torsion spring 19 mounted on the rotating shaft 10, and the force-applying direction of the torsion spring 19 causes the side wall of the stop 8 to tend to cover the bypass port 7.

[0010] Furthermore, a notch 1202 is formed at the top of the guard plate 12; the side of the notch 1202 near the roller 4 forms an acute angle 1203 with the beginning of the arc edge 1201 and the end of the acute angle has a rounded arc, which is used to allow the material that has not entered the material trough 5 and travels with the roller 4 to the end of the acute angle 1203 to be removed from the surface of the roller 4. The lowest positions of the notches 1202 of two adjacent guard plates 12 are staggered, which is used to cause the material that reaches the guard plate 12 to become unstable and enter the channel 18.

[0011] Furthermore, it also includes a guide rail 14 arranged parallel to the axis of the roller 4, the guard plate 12 is sleeved on the guide rail 14, and a partition 15 is installed between the guard plates 12 to maintain the width of the channel 18. It also includes locking members 13 provided at both ends of the guide rail 14 to clamp and fix all the guard plates 12 on the guide rail 14.

[0012] Furthermore, it also includes a storage box 16 located below the roller 4. The storage box 16 extends upward along the channel 18 toward the surface of the roller 4 on the side close to the roller 4, forming an extension edge 17, which is used to guide the material discharged from the channel 18 into the storage box 16. The end of the arc-shaped edge 1201 is closer to the lowest position of the outer circular surface of the roller 4 than the extension edge 17.

[0013] Furthermore, each of the material troughs 5 is provided with at least one guard plate 12 located in the area of ​​the material trough 5 in the axial direction of the roller 4, for guiding the material in the material trough 5 to the end of the arc-shaped edge 1201 for release.

[0014] The beneficial technical effects of this application are as follows: The vibratory feeder provided by this application opens a bypass port in the direction of the roller rotation at the discharge port and covers the outside of the bypass port with a baffle. The baffle can be opened by the thrust generated by the movement of material that has not fully entered the receiving trough and protrudes from the surface of the receiving trough, allowing the material to pass through the bypass port and leave the discharge port area with the roller, completely avoiding the material being crushed. When such material enters the front end of the guard plate, it is guided to the guard plate and thus detaches from the roller surface. Under the action of the notch, it falls into the channel and enters the collection box for separation. Material that has fully entered the receiving trough enters the holding range of the arc-shaped edge and is released into the blister pack as the roller rotates to the end of the arc-shaped edge. This effectively ensures the integrity of the material entering the blister pack, which is far superior to the prior art. Attached Figure Description

Detailed Implementation

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Please see Figure 1-8 A vibrating feeder includes a guide plate 2 with an internal slide 3, a roller 4 located below the discharge port 6 of the slide 3, and a protective plate 12 located outside the roller 4. The outer circumference of the roller 4 is provided with a material receiving groove 5 adapted to the discharge port 6. In this embodiment, the longitudinal direction of the material receiving groove 5 is parallel to the axial direction of the roller 4. At the discharge port 6, a bypass port 7 is formed through the side wall of the slide 3 in front of the roller 4 in the direction of rotation. The outside of the bypass port 7 is covered with a baffle 8 that can be opened by the thrust generated by the movement of material that has not fully entered the material receiving groove 5 and protrudes from the opening surface of the material receiving groove 5, allowing the material to pass through the bypass port 7. In this embodiment, the baffle 8 is an independent baffle corresponding to the bypass port 7. When each baffle is pushed open, the baffles corresponding to the other bypass ports 7 remain in the state of covering the bypass ports 7 to guide the material normally.

[0026] As a further preferred embodiment, please refer to the following: Figure 8 As the path of the slide 3 extends to the surface of the roller 4, it smoothly turns from a vertical direction to an oblique direction, so as to smoothly turn the long material from a vertical state to a horizontal direction consistent with the longitudinal direction of the receiving trough 5, so as to facilitate the material entering the receiving trough 5. At the discharge port 6, the guide wall edges on the slide 3 corresponding to the two longitudinal ends of the receiving trough 5 are respectively aligned with the two longitudinal end faces of the receiving trough 5. That is, at the discharge port 6, relative to the turned material, a guide wall located at the tail of the material extends smoothly in an arc from the vertical direction toward the receiving trough 5 and its opening edge is aligned with the corresponding end face of the receiving trough 5. Another guide wall located at the head of the material extends along the longitudinal direction of the receiving trough 5 and its opening edge is aligned with the corresponding end face of the receiving trough 5. It can be understood that the width of the bypass port 7 covers the area of ​​the two guide walls at the discharge port 6.

[0027] According to the structure provided in this embodiment, the vibratory feeder provided in this application opens a bypass port 7 in the direction of rotation of the roller 4 at the discharge port 6 and covers the outside of the bypass port 7 with a baffle 8. The baffle 8 can be opened by the thrust generated by the material that has not fully entered the material trough 5 and protrudes from the opening of the material trough 5, allowing the material to pass through the bypass port 7 and leave the discharge port 6 area with the roller 4, completely avoiding the material being crushed, which is far superior to the prior art.

[0028] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8The guard plate 12 is a thin sheet structure and multiple plates are spaced apart along the axial direction of the roller 4. The guard plate 12 has an arc-shaped edge 1201 that is adapted to the outer circle of the roller 4. A channel 18 is formed between any two guard plates 12. The arc-shaped edge 1201 and the channel 18 are used to guide materials that have entered the material tank 5 and those that have not entered the material tank 5 to different discharge positions. According to the structure provided in this embodiment, the material that has not fully entered the material tank 5 and protrudes from the opening of the material tank 5 is guided to the guard plate 12 when it enters the front end of the guard plate 12, thereby detaching from the surface of the roller 4. Under the action of the notch 1202, it falls into the channel 18 and enters the storage box 16 through the channel 18, thus separating from the normally moving material. The material that has fully entered the material tank 5 enters the holding range of the arc-shaped edge 1201 and is released into the formed blister pack as the roller 4 rotates to the end of the arc-shaped edge 1201. This effectively ensures the integrity of the material entering the blister pack, which is far superior to the prior art.

[0029] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8 It also includes a vibratory feeder 1, and the slide 3 of the guide plate 2 is connected to the output end of the vibratory feeder 1 for conveying materials output from the vibratory feeder 1 in a row. In this way, capsules and tablets can be automatically fed through the vibratory feeder 1, which is conducive to improving the level of automation.

[0030] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8 One end of the stop 8 is rotatably supported by the rotating shaft 10, the free end of the stop 8 faces the roller 4, and the side wall of the free end is used to cover the bypass opening 7; it also includes a force-applying component for making the side wall of the stop 8 cover the bypass opening 7, see details. Figure 3 Through the action of the force-applying component, the bypass port 7 is kept in a normally closed state to guide and convey the material, allowing the material to smoothly enter the receiving trough 5. When there is material that has not fully entered the receiving trough 5 and is stuck at the opening of the receiving trough 5, as the roller 4 rotates, the material moves forward towards the bypass port 7. The thrust of the material during its movement pushes the stop 8 to rotate outward around the rotating shaft 10. The opening size can adaptively change according to the size of the material and its position, allowing the material to smoothly pass through the bypass port 7 and leave the discharge port 6 area, avoiding the material from being crushed and fully protecting the integrity of the material. After the current material passes through, the stop 8 automatically resets and covers the bypass port 7 under the action of the force-applying component to guide the subsequent material to the receiving trough 5 normally. In this embodiment, both ends of the rotating shaft 10 can be connected to the guide plate 2 through a rotating support structure such as a rotating seat or a bearing seat.

[0031] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8The force-applying component is a counterweight 9 mounted on the stop 8. The distance between the center of gravity of the counterweight 9 and the center of the rotating shaft 10 is adjustable. In this way, the closing force of the stop 8 can be easily adjusted by adjusting the center of gravity of the counterweight 9, thereby adapting to materials of different hardness. In this embodiment, the counterweight 9 is a bolt screwed onto the outside of the opening direction of the stop 8. The closing force can be adjusted by adjusting the depth of the bolt or the position of the nut mounted on the bolt. That is, the deeper the bolt is screwed in, the smaller the closing force, and vice versa. It can be understood that the weight of the stop 8 itself is also one of the force-applying components in this embodiment.

[0032] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8 The force-applying component is a torsion spring 19 mounted on the rotating shaft 10. The force applied by the torsion spring 19 tends to keep the side wall of the stop 8 covering the bypass port 7. In this way, through the elastic force of the torsion spring 19, the elastic force of the stop 8 can make the stop 8 more sensitive to movement, faster to reset, and without rebound.

[0033] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8 The top of the guard plate 12 has a notch 1202; the side of the notch 1202 near the roller 4 forms an acute angle 1203 with the beginning of the arc edge 1201 and the end of the acute angle has a rounded arc, which is used to allow the material that has not entered the material trough 5 and has traveled with the roller 4 to the end of the acute angle 1203 to be removed from the surface of the roller 4. The lowest positions of the notches 1202 of two adjacent guard plates 12 are staggered, which is used to make the material that reaches the guard plate 12 unstable and enter the channel 18. According to the above structure provided in this embodiment, when the material reaches the guard plate 12, it is guided by the notch 1202 toward the side of the roller 4. Since the positions of the notches 1202 of two adjacent guard plates 12 are different, the slope of the corresponding side of the two guard plates 12 is different. In this way, the material will become skewed and unstable and slide toward the channel 18, thereby separating it from the material that is traveling normally in the material trough 5.

[0034] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8It also includes a guide rail 14 parallel to the axis of the roller 4, a protective plate 12 sleeved on the guide rail 14, and a partition 15 installed between the protective plates 12 to maintain the width of the channel 18. It also includes locking members 13 at both ends of the guide rail 14 to clamp and fix all the protective plates 12 on the guide rail 14. In this embodiment, the cross section of the guide rail 14 is rectangular, and both ends are supported by the support 11. The corresponding protective plates 12 have rectangular mating openings or mating holes. The locking member 13 is a locking block that is also sleeved on the guide rail 14. After the protective plates 12 and the partitions 15 are adjusted to the set position on the guide rail 14, the locking block is fastened to the guide rail 14 with fasteners to complete the installation, clamping, positioning and fixing of the protective plates 12 and the partitions 15. According to the above structure provided in this embodiment, the protective plates 12 can be installed and positioned in an adjustable manner to maintain their relative position with the roller 4, thereby ensuring the reliability and stability of the feeder.

[0035] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8 It also includes a storage box 16 located below the roller 4. The storage box 16 extends upward along the channel 18 toward the surface of the roller 4 on the side near the roller 4, forming an extension edge 17, which is used to guide the material out of the channel 18 into the storage box 16. The end of the arc-shaped edge 1201 is closer to the lowest position of the outer circular surface of the roller 4 than the extension edge 17. According to the structure provided in this embodiment, materials in different states can be separated and output to different positions. In this embodiment, the end of the arc-shaped edge 1201 is adapted to the position of the empty blister pack on the blister packaging machine. The material is supported by the arc-shaped edge 1201 in the material trough 5 and moves with the roller 4. When it is at the lowest position of the outer circular surface of the roller 4, the opening of the material trough 5 faces downward. At this time, the material trough 5 leaves the end of the arc-shaped edge 1201, the material loses its support and falls from the material trough 5 into the empty blister pack, completing one feeding action; while the material out of the extension edge 17 enters the storage box 16, ensuring that the material entering the blister pack is correct and improving the feeding quality.

[0036] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 8 Each material trough 5 is equipped with at least one guard plate 12 located in the area of ​​the material trough 5 along the axial direction of the roller 4, which is used to guide the material in the material trough 5 to the end of the arc edge 1201 for release. In this embodiment, each material trough 5 area is provided with two guard plates 12. In this way, it can be ensured that the material in the material trough 5 is stably located in the material trough 5 during the rotation of the roller 4 until the end of the arc edge 1201, which further improves the reliability of this feeder.
