Description

Technical Field

[0001] This application belongs to the field of blister packaging machines, and particularly relates to a feeding-type continuous capsule feeder. Background Technology

[0002] Existing blister packaging machines require frequent stops during the capsule feeding process. Specifically, when the blister pack moves to the next station, the feeder must stop discharging to prevent capsules from falling outside the blister openings. Feeding can only resume after the blister pack has come to a complete stop. This intermittent operation significantly reduces the effective operating time of the equipment and results in low production efficiency. Therefore, it is necessary to solve the aforementioned technical problems. Utility Model Content

On the other hand, during the process of the drive mechanism driving the inner box to return, the capsules can also enter the vibratory feeder from the hopper in sequence and enter the holes on the target blister pack through the guide tube, the equalization box, and the feeding slide set on the feeding block. Because the inner box and the second feeding component integrated on the inner box can move precisely synchronously or in the opposite direction to the blister pack, the feeding chute outlet can always dynamically track and align with the target blister opening when the blister pack moves. This enables continuous and uninterrupted feeding of capsules while the blister pack is in motion and completely eliminates the invalid time caused by the machine having to stop and wait due to the movement of the blister pack in traditional feeding methods. Therefore, the feeding continuous capsule feeder provided in this application can significantly improve the feeding efficiency of blister packaging machines, which is far superior to the prior art.

In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] Please refer to the following: Figures 1 to 6 The present application provides a continuous capsule feeder with a feeding mechanism. This continuous capsule feeder includes an outer housing 101, an inner housing 103, a first feeding assembly, a second feeding assembly, and a drive mechanism. Wherein:

[0042] The outer housing 101 forms a linear guide 102 parallel to the moving direction of the target blister pack; the inner housing 103 is slidably connected to the linear guide 102; the first feeding assembly includes a hopper 104 and a vibrating plate 105 respectively connected to the outer housing 101 and communicating with each other, and also includes a guide pipe 106 communicating with the vibrating plate 105, the guide pipe 106 being an elastic flexible hose; the second feeding assembly includes a leveling box 107 connected to the inner housing 103, and also includes a feeding block 108 disposed below the leveling box 107, the feeding block 108 forming a feeding chute 109 communicating with the leveling box 107, the guide pipe 106 being connected to the top of the leveling box 107 and communicating with the feeding chute 109 through the leveling box 107; the drive mechanism is connected to the inner housing 103 and is used to drive the inner housing 103 to reciprocate on the linear guide 102.

[0043] According to the structure provided in this embodiment, in the continuous capsule feeder provided in this embodiment, on the one hand, the driving mechanism can drive the inner box 103 to move along the linear track 102 provided on the outer box 101 and move synchronously with the blister pack. The vibrating plate 105 in the first feeding assembly can continuously vibrate and transport the capsules through the elastic guide tube 106 to the uniform box 107 fixed on the inner box 103. After uniform feeding, the capsules can be quickly and accurately dropped into the corresponding holes on the target blister pack through the feeding slide 109 provided on the feeding block 108. On the other hand, during the process of the driving mechanism driving the inner box 103 to return, the capsules can also enter the vibrating plate 105 from the hopper 104 in sequence and enter the holes on the target blister pack through the guide tube 106, the uniform box 107 and the feeding slide 109 provided on the feeding block 108. Since the inner box 103 and the second feeding component integrated on the inner box 103 can move precisely synchronously or in the opposite direction to the blister pack, the outlet of the feeding chute 109 can always dynamically track and align with the target blister hole when the blister pack moves. This enables continuous and uninterrupted feeding of capsules while the blister pack is in motion and completely eliminates the invalid time caused by the machine having to stop and wait due to the movement of the blister pack in traditional feeding methods. Therefore, the feeding continuous capsule feeder provided in this embodiment can significantly improve the feeding efficiency of the blister packing machine, which is far superior to the prior art.

[0044] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The material distribution box 107 includes a top cover plate 110, a material frame 111, and a guide plate 112. It also includes a vibration mechanism that is connected to the material frame 111 and is used to drive the material frame 111 to reciprocate. The top cover plate 110, the material frame 111, and the guide plate 112 cooperate to form a first cavity 113. The guide pipe 106 is connected to the top cover plate 110. Multiple sets of guide holes 114 are formed on the guide plate 112. Multiple sets of discharge blocks 108 are arranged side by side and form multiple sets of discharge slides 109 that correspond one by one with the guide holes 114.

[0045] According to the structure provided in this embodiment, in the continuous capsule feeder provided in this embodiment, the first cavity 113 formed by the top cover plate 110, the material frame 111, and the guide plate 112 used to form the uniform material box 107 can be used to receive capsules from the guide tube 106. In this way, during the process of the vibration mechanism driving the material frame 111 to vibrate continuously, the capsules in the first cavity 113 can be evenly distributed in the first cavity 113 and accurately guided into the discharge slide 109 through the multiple sets of guide holes 114 neatly arranged on the guide plate 112. This is conducive to further improving the feeding efficiency of the continuous capsule feeder in this embodiment.

[0046] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The vibration mechanism includes a feeding motor 115, a crank seat 116, a guide post 117, a floating seat 118, a crank 119, and a connecting rod 120. The feeding motor 115, the crank seat 116, and the guide post 117 are fixedly connected to the inner housing 103. The axial direction of the guide post 117 is parallel to the axial direction of the guide hole 114. The floating seat 118 is connected to the material frame 111 and slidably connected to the guide post 117. The crank 119 is connected to the output end of the feeding motor 115. The two ends of the connecting rod 120 are respectively hinged to the crank 119 and the floating seat 118 so that the floating seat 118 can be driven by the feeding motor 115 and move along the axial direction of the guide post 117.

[0047] According to the structure provided in this embodiment, in the continuous capsule feeder provided in this embodiment, the uniform motor 115 can drive the crank 119 to rotate and drive the floating seat 118 to move axially along the guide post 117 fixed on the inner box 103 via the connecting rod 120. In this way, the material frame 111 connected to the floating seat 118 can drive the entire uniform box 107 to vibrate axially along the guide post 117. As a result, the capsules in the first cavity 113 can be efficiently and accurately guided into the feeding chute 109 through the guide hole 114 under the action of directional vibration. This is also conducive to further improving the feeding efficiency of the continuous capsule feeder in this embodiment.

[0048] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The second feeding assembly also includes a metering mechanism, which includes a vertical plate 121, a bottom plate 122, and a middle cover plate 123, as well as an upper gate 124, a lower gate 125, a metering tube 126, and a stop pin 127. The vertical plate 121 is connected to the inner housing 103. The bottom plate 122 and the middle cover plate 123 are respectively connected to the vertical plate 121 and are interconnected to form a second cavity 128. The upper gate 124 and the lower gate 125 are arranged in parallel and spaced apart in the second cavity 128 and each has a top 129 extending out of the second cavity 128. The metering tube 126 passes through the bottom plate 122, the lower gate 125, the upper gate 124, and the middle cover plate 123 in sequence. The feeding chute 109 is connected to one end of the metering tube 126, and the end of the metering tube 126 away from the feeding block 108 is connected to the metering tube 126. The material guide hole 114 is movable and communicates with the material guide hole 114. The material stop pin 127 is connected to the upper gate plate 124 and the lower gate plate 125 respectively and is located in the holes of the upper gate plate 124 and the lower gate plate 125 for the metering tube 126 to pass through. The metering tube 126 forms a through hole 130 for the material stop pin 127 to pass through. The second feeding assembly also includes an adjustment mechanism for driving the upper gate plate 124 and the lower gate plate 125 to move in the second cavity 128 respectively. The moving direction of the upper gate plate 124 and the lower gate plate 125 is perpendicular to their own normal direction and can drive the material stop pin 127 to enter or exit the metering tube 126 from the through hole 130. Here, the connection between the material stop pin 127 and the lower gate plate 125 or the upper gate plate 124 can adopt existing technologies such as welding, snap-fit, and threaded connection.

[0049] According to the structure provided in this embodiment, in the continuous capsule feeder provided in this embodiment, when the adjusting mechanism drives the upper gate 124 and the lower gate 125 to move in the second cavity 128 in a direction perpendicular to their own normal, the baffle pin 127 connected to the upper gate 124 and the lower gate 125 can alternately enter or exit the through hole 130 on the metering tube 126. Thus, when the adjusting mechanism drives the upper gate 124 to move and its upper stop pin 127 to exit the metering tube 126, the capsule enters the metering section between the upper gate 124 and the lower gate 125. Subsequently, the upper gate 124 resets, causing the stop pin 127 to insert into the through hole 130 and block the entry of subsequent capsules. At the same time, the adjusting mechanism drives the lower gate 125 to move, causing its upper stop pin 127 to exit the through hole 130. Thus, the capsules in the metering section fall precisely into the blister pack holes via the feeding chute 109. After the capsule filling is completed, the lower gate 125 immediately resets, causing its stop pin 127 to re-insert into the metering tube 126 through the through hole 130, forming a metering cycle of alternating opening and closing of the two gates. Combined with the synchronous movement of the inner box 103, this enables precise quantitative filling of capsules during the continuous movement of the blister pack, which is beneficial for further improving the feeding efficiency of the continuous capsule feeder in this embodiment. It can be understood that the metering section between the upper gate 124 and the lower gate 125 in this embodiment can be set to accommodate only a single capsule or a fixed number of capsules at the same time. In the specific implementation process, you can set it up flexibly as needed, which will not be elaborated on here.

[0050] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The adjustment mechanism includes a spring seat 131 connected to the base plate 122 and a spring 132 connected to the spring seat 131, and a cylinder 133 connected to the inner housing 103; the spring 132 is placed between the upper gate plate 124 and the spring seat 131, and also between the lower gate plate 125 and the spring seat 131; the output direction of the cylinder 133 is parallel to the elastic deformation direction of the spring 132, and the top 129 is used to abut against the output end of the cylinder 133.

[0051] According to the structure provided in this embodiment, in the continuous capsule feeder provided in this embodiment, when the output end of the cylinder 133 abuts against the top 129 on the upper gate 124 or the lower gate 125, the stop pins 127 on the upper gate 124 and the lower gate 125 can be inserted into the through hole 130; and when the output shaft of the cylinder 133 retracts, the spring 132 connected to the base plate 122 by the spring seat 131 can push the upper gate 124 and the lower gate 125 to reset, which can effectively save the reset time of the upper gate 124 and the lower gate 125, thereby further improving the feeding efficiency of the continuous capsule feeder in this embodiment.

[0052] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The metering tube 126 forms a square segment 134 in its middle portion; the two end faces of the square segment 134 abut against the middle cover plate 123 and the bottom plate 122 respectively in the axial direction of the metering tube 126. According to the structure provided in this embodiment, the square segment 134 formed in the middle portion of the metering tube 126 abuts against the middle cover plate 123 and the bottom plate 122 respectively in the axial direction, which can firmly constrain the metering tube 126 in the second cavity 128. This can effectively limit the axial movement of the metering tube 126 during the gate operation and ensure that the through hole 130 on the metering tube 126 can always maintain precise alignment with the stop pin 127. This is also conducive to further improving the feeding efficiency of the feeding continuous capsule feeder in this embodiment.

[0053] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The holes on the upper gate 124 and lower gate 125 for the metering tube 126 to pass through are formed to fit the shape of the square segment 134 and can restrict the rotation of the metering tube 126 around its own central axis. According to the structure provided in this embodiment, the holes on the upper gate 124 and lower gate 125 for the metering tube 126 to pass through can be set as rectangular holes that fit the square segment 134. This allows the double gates to move laterally while strictly restricting the rotation of the metering tube 126 around its own central axis, ensuring that the axis of the through hole 130 on the metering tube 126 is always orthogonally aligned with the movement trajectory of the stop pin 127. It can be understood that the length of the rectangular hole in the axial direction of the stop pin 127 is adapted to the moving distance of the upper gate 124 and lower gate 125, which is also conducive to further improving the feeding efficiency of the feeding continuous capsule feeder in this embodiment.

[0054] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The continuous capsule feeder also includes a guide rail 135 connected to the base plate 122, a connecting plate 136 slidably connected to the guide rail 135, and a locking mechanism for locking the connecting plate 136 to the guide rail 135; the feeding block 108 is connected to the connecting plate 136. According to the structure provided in this embodiment, when a capsule gets stuck in a feeding chute 109, loosening the locking mechanism can push the connecting plate 136 to slide laterally along the guide rail 135, so that the corresponding feeding block 108 can be moved away from the working position of the blister pack, exposing the blocked feeding chute 109 for quick unblocking and cleaning; after cleaning, sliding the connecting plate 136 in the opposite direction will accurately reset the feeding block 108 to the working position and lock it in place, which also helps to further improve the feeding efficiency of the continuous capsule feeder in this embodiment.

[0055] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6The locking mechanism includes a locking bolt 137 and a locking plate 138 connected to the connecting plate 136; the locking plate 138 is connected to the middle cover plate 123 by the locking bolt 137. According to the structure provided in this embodiment, when it is necessary to clean the blocked feeding chute 109, it is only necessary to loosen the locking bolt 137 to release the constraint of the locking plate 138 on the connecting plate 136. After cleaning, tightening the locking bolt 137 will rigidly press the connecting plate 136 onto the middle cover plate 123 through the locking plate 138. This is also conducive to further improving the feeding efficiency of the feeding continuous capsule feeder in this embodiment.

[0056] In another embodiment of this application, please refer to [the relevant document / reference]. Figures 1 to 6 The driving mechanism includes a servo motor 139, a lead screw 140, and a nut 141. The servo motor 139 is connected to the outer housing 101, the lead screw 140 is connected to the power end of the servo motor 139 and is parallel to the linear guide 102, and the nut 141 is connected to the inner housing 103 and threadedly connected to the lead screw 140. According to the structure provided in this embodiment, since the lead screw 140 is parallel to the linear guide 102, when the servo motor 139 drives the lead screw 140 to rotate, the nut 141 threadedly connected to the lead screw 140 can drive the inner housing 103 to perform linear displacement along the linear guide 102 formed on the outer housing 101. This can effectively improve the moving speed and moving stability of the inner housing 103, and is also conducive to further improving the feeding efficiency of the feeding continuous capsule feeder in this embodiment.

[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
