Description

Technical Field

[0001] The present invention relates to the technical field of automated production lines, in particular to a material pushing mechanism for preventing material piling. Background Art

[0002] In existing automated production lines, material transportation typically involves multiple stages, including feeding, sorting, and packaging. Due to factors such as the shape, size, and weight of the materials, material accumulation is prone to occur in these stages, especially in specific areas such as turns and junctions on the conveyor line.

[0003] Vials, a common pharmaceutical packaging container, are prone to accumulation and jamming during conveyance. The triangular area on the conveyor line (formed by the convergence of two or more conveyor lanes) is a high-incidence area for bottle jams. In this triangular area, due to spatial constraints and changes in conveying direction, bottles are prone to collision and compression, resulting in three or more bottles becoming stuck, creating the so-called "triangle zone" bottle jam.

[0004] Material accumulation can cause production line blockages, reduce production efficiency, and even damage equipment. Currently, there are two main methods to address material accumulation: manual cleaning, which involves assigning personnel to monitor workstations in real time and clearing materials as they accumulate; and pneumatic conveying, which involves using compressed air to blow vials apart to prevent accumulation. However, manual intervention is inefficient, requires real-time monitoring, is labor-intensive, and can easily pollute the pharmaceutical production environment. Pneumatic conveying, on the other hand, consumes large amounts of compressed air, which is costly, and the airflow can affect the stability of the vials, posing certain safety risks. Summary of the Invention

[0005] In order to solve the above problems, the present invention provides an anti-piling pushing mechanism that realizes precise control of the material conveying process, effectively prevents material accumulation, and improves production efficiency.

[0006] In order to achieve the above-mentioned purpose, the present invention is designed to prevent the material from piling up and push the material mechanism, including:

[0007] base;

[0008] A plurality of first material guide strips are arranged in parallel and spaced apart on the base, wherein the first material guide strips define a feeding channel;

[0009] a plurality of second material guiding strips spaced apart from and parallel to the first material guiding strips, each second material guiding strip correspondingly separating one of the feed channels to define a material guiding channel;

[0010] A plurality of shifting rods, each shifting rod being correspondingly arranged in a transition area between a feed channel and a guide channel;

[0011] In which, the first material guide bar and the second material guide bar are located on the same side of the base, and jointly define a working area on one side of the base; the shift rod at least partially passes through the base and extends outside the working area; a driving device is provided outside the working area, and the driving device is configured to drive the shift rod to reciprocate along the feeding direction of the feed channel to push the material accumulated in the transition area between the feed channel and the material guide channel.

[0012] In order to simply and effectively realize the driving of the shift rod, the driving device includes a driving mechanism, a pull rod, a bearing seat, a rotating shaft, a transmission mechanism and a slider. The bearing seat is vertically arranged and rotatably matched with the rotating shaft; one end of the pull rod is hingedly connected to the power output end of the driving mechanism, and the other end is fixedly connected to one end of the rotating shaft; the transmission mechanism connects the rotating shaft and the slider, and is used to convert the rotational motion of the rotating shaft into the reciprocating linear motion of the slider; the slider drives the shift rod to reciprocate in the horizontal direction.

[0013] In order to solve the problem of synchronous movement of multiple shift rods, it also includes a synchronization rod extending along the width direction of the feed channel, and multiple shift rods are arranged at intervals on the synchronization rod; there are two driving devices, and the two sliders corresponding to the two driving devices are respectively fixedly connected to the two ends of the synchronization rod.

[0014] In order to improve the driving efficiency, it also includes a driving rod extending along the width direction of the feeding channel, and the two pull rods corresponding to the two driving devices are hinged at both ends of the driving rod.

[0015] In order to adapt to different application scenarios and design requirements, the transmission mechanism is a crank-connecting rod mechanism, a cam slider mechanism, a gear rack mechanism or an eccentric wheel mechanism.

[0016] In order to optimize the spatial layout, the two driving devices, the synchronization rod and the driving rod are located on a side of the base facing away from the working area, and together define an avoidance space.

[0017] In order to enable the material to move more smoothly, the heads of the first material guiding strip and the second material guiding strip are cut along an inclined plane, and the inclined plane forms a predetermined angle with the angle between the feed channel and the material guiding channel.

[0018] A further solution is that the heads of the first guide bar and the second guide bar form a first accommodating groove, and a cylindrical guide member is rotatably arranged in the first accommodating groove, and the cylindrical guide member is used to guide the material along the inclined surface into the corresponding feed channel or guide channel.

[0019] In order to guide and position the material more accurately, a second accommodating groove is also formed at the head of the second material guide bar, and the second accommodating groove is adapted to the outer shape of the part of the shift rod placed in the working area, and the base is provided with an oblong hole adapted to the shift rod; when the shift rod moves along the oblong hole into the second accommodating groove, the shift rod is coaxially arranged with the cylindrical material guide part at the head of the second material guide rod.

[0020] The anti-piling pushing mechanism designed by the present invention realizes precise control of the material conveying process by arranging a shift rod in the working area to accurately push the material, arranging the driving device outside the working area for easy maintenance, and arranging a bevel surface and a cylindrical material guide at the head of the guide bar to guide the smooth transition of the material; at the same time, the synchronization rod and the driving rod are used to make multiple shift rods move synchronously and expand the working range, and the design of the shift rod passing through the base reduces the impact on the normal conveying of the material, and the limit groove and the oblong hole are used to ensure the stability of the shift rod movement, thereby effectively preventing material accumulation, improving production efficiency, reducing production costs, and having good application prospects.

DETAILED DESCRIPTION

[0030] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0031] Example 1.

[0032] like Figures 1 to 8 As shown, the anti-stacking pushing mechanism described in this embodiment is mainly used to prevent the accumulation and jamming of vials in the transition area between the feed channel and the guide channel due to collision and squeezing between the vials during the transportation process. The anti-stacking pushing mechanism includes:

[0033] Base 10; provides support for the entire mechanism;

[0034] A plurality of first material guide strips 20 are arranged in parallel and spaced apart on the base 10 , wherein the first material guide strips 20 define a material feeding channel 30 ;

[0035] a plurality of second material guiding strips 40 spaced apart from and parallel to the first material guiding strips 20 , each second material guiding strip 40 correspondingly separating one of the feed channels 30 to define a material guiding channel 50 ;

[0036] A plurality of shifting rods 60, each shifting rod 60 is correspondingly disposed in a transition area between a feed channel 30 and a guide channel 50;

[0037] In which, the first guide bar 20 and the second guide bar 40 are located on the same side of the base 10, and jointly define a working area 70 on one side of the base 10; the shift rod 60 at least partially passes through the base 10 and extends outside the working area 70; a driving device 80 is provided outside the working area 70, and the driving device 80 is configured to drive the shift rod 60 to reciprocate along the feeding direction of the feed channel 30 to push the material accumulated in the transition area between the feed channel 30 and the guide channel 50.

[0038] For specific implementation, see Figures 1 to 4 As shown, see Figures 1 to 4As shown, a plurality of first guide bars 20 are arranged in parallel and at intervals on the base 10, and are used to guide the vials into the feed channel 30. Subsequently, a plurality of second guide bars 40 are arranged in parallel and at intervals with the first guide bars 20, and are used to separate the guide channel 50 and guide the vials into the feed channel 30, thereby further dividing the materials in a regular manner and facilitating the operation of subsequent processes, such as filling after regular arrangement.

[0039] When the vials are conveyed along the feed channel 30, if accumulation occurs in the transition area between the feed channel 30 and the guide channel 50, such as the "triangle area" bottle jam problem, refer to Figure 5 As shown, the driving device 80 drives the shifting rod 60 to perform reciprocating motion, pushing the stacked vials back into the material guiding channel 50 to ensure smooth transportation of the vials.

[0040] It can be understood that the mechanism is not only suitable for conveying vials, but can also be used for conveying materials of other shapes and sizes, such as ampoules, tablets, etc., reflecting its good versatility.

[0041] Specifically, if Figures 6 to 8 As shown, in order to simply and effectively realize the driving of the shift rod 60, the driving device 80 includes a driving mechanism 81, a pull rod 82, a bearing seat 83, a rotating shaft 84, a transmission mechanism 85 and a slider 86. The bearing seat 83 is vertically arranged and rotatably matched with the rotating shaft 84; one end of the pull rod 82 is hingedly connected to the power output end of the driving mechanism 81, and the other end is fixedly connected to one end of the rotating shaft 84; the transmission mechanism 85 connects the rotating shaft 84 and the slider 86, and is used to convert the rotational motion of the rotating shaft 84 into the reciprocating linear motion of the slider 86; the slider 86 drives the shift rod 60 to reciprocate in the horizontal direction.

[0042] In a specific implementation, the driving mechanism 81 can be a device that can provide reciprocating power, such as an electric screw, a cylinder, etc. For example, a cylinder can be used as the driving mechanism 81 to provide precise ejection stroke control, that is, the driving mechanism 81 outputs power, drives the rotating shaft 84 to rotate through the pull rod 82, and the rotating shaft 84 drives the slider 86 to perform reciprocating linear motion through the driving mechanism 81. The reciprocating linear motion of the slider 86 drives the lever 60 to perform reciprocating motion, thereby achieving the pushing of the material. In this embodiment, the transmission mechanism 85 is a crank-connecting rod mechanism, a cam slider mechanism, a gear rack mechanism, or an eccentric wheel mechanism. In one embodiment, the transmission mechanism 85 is as follows: Figure 8 The crank-connecting rod mechanism shown is preferably a crank-connecting rod mechanism, which has the advantages of simple structure, high transmission efficiency, easy maintenance, high movement reliability and small space occupation, and can meet the requirements of the mechanism for the transmission mechanism.

[0043] In addition, if Figure 6As shown, the bearing seat 83 is vertically arranged, which can make full use of the vertical space and arrange the main components of the driving mechanism 80 (such as the cylinder, crank-connecting rod mechanism, etc.) below the working area 70, thereby avoiding occupying the horizontal space of the working area 70, leaving more space for the transportation of materials and the movement of the shift rod 60. In addition, the vertically arranged bearing seat 83 also helps the driving device 80 to be as far away from the working area 70 as possible, thereby avoiding possible contamination of the materials transported in the working area during its operation. For example, when the driving device 80 is driven by a cylinder, the vertical arrangement can effectively isolate the impact of potential air leakage on the working area.

[0044] In some embodiments, as Figure 7 and Figure 8 As shown, the mechanism further includes a synchronization rod 87 extending along the width of the feed channel 30, with multiple shifting rods 60 spaced apart on the synchronization rod 87. Two drive devices 80 are provided, and two corresponding sliders 86 are fixedly connected to the ends of the synchronization rod 87. In this embodiment, by introducing the synchronization rod 87, two drive devices 80 can be used to drive multiple shifting rods 60, eliminating the need for a separate drive device for each shifting rod 60. This significantly simplifies the mechanism structure, reduces the number of drive devices, and lowers manufacturing and maintenance costs.

[0045] In some embodiments, as Figure 7 As shown, the embodiment further includes a drive rod 88 extending along the width direction of the feed channel 30, and two pull rods 82 corresponding to the two drive devices 80 are hingedly connected to the ends of the drive rod 88. In this embodiment, by introducing the drive rod 88, a single drive mechanism 81 can drive both drive devices 80, thereby further simplifying the structure, reducing costs, ensuring synchronous movement of the two drive devices, enhancing the stability of the mechanism, and facilitating power transmission.

[0046] In some embodiments, as Figure 6 and Figure 7 As shown, in order to optimize the spatial layout, the two driving devices 80 , the synchronization rod 87 and the driving rod 88 are located on the side of the base 10 facing away from the working area 70 , and together define an escape space 90 .

[0047] With this structural design, the drive device 80, synchronization rod 87 and drive rod 88 are arranged on the side away from the working area 70, which can effectively separate the working area 70 and the drive device 80 and other components, and further optimize the spatial layout: Figure 6As shown, the formed avoidance space 90 can provide installation space for the material conveying mechanism on the base 10, facilitating the conveying and transfer of materials. This can also avoid the contamination of the working area 70 by the moving parts in the conveying mechanism, facilitate maintenance, and improve safety, thereby making the anti-stacking and pushing mechanism more compact, efficient and safe.

[0048] In some embodiments, as Figures 1 to 4 As shown, the heads of the first material guiding strip 20 and the second material guiding strip 40 are cut along an inclined surface 100 , and the inclined surface 100 forms a predetermined angle with the angle between the feed channel 30 and the material guiding channel 50 .

[0049] Specifically, the inclined surface 100 is the slanted surface formed by cutting the ends of the first and second guide bars 20 and 40. The angles formed between the inclined surface 100 and the feed channel 30 and the guide channel 50 are predetermined, such as 30 degrees, 45 degrees, or 60 degrees. During operation, the inclined surface 100 prevents material from becoming stuck between the guide bars 20 and 40. Specifically, if the ends of the guide bars were vertical, material could easily become stuck between the bars, especially with large or irregularly shaped materials. The design of the inclined surface 100 effectively prevents this from occurring, allowing the material to pass smoothly through the guide bars.

[0050] In some embodiments, as Figure 2 As shown, the heads of the first and second guide strips 20 and 40 form a first receiving groove 101. A cylindrical guide member 102 is rotatably disposed within the first receiving groove 101. The cylindrical guide member 102 is used to guide the material along the inclined surface 100 into the corresponding feed channel 30 or guide channel 50. The cylindrical guide member 102 can form a rolling contact surface between the material and the guide strips, thereby significantly reducing the friction between the material and the guide strips, thereby enhancing the guiding effect on the material and further reducing the risk of material accumulation or jamming.

[0051] In some embodiments, as Figure 2 and Figure 5As shown, the head of the second material guide bar 40 also forms a second receiving groove 103. This second receiving groove 103 matches the shape of the portion of the lever 60 positioned within the working area 70. The base 10 is provided with an oblong hole 11 that matches the lever 60. When the lever 60 moves along the oblong hole 11 into the second receiving groove 103, it is coaxially arranged with the cylindrical material guide member 102 at the head of the second material guide bar. In this embodiment, the lever 60 is normally concealed within the second receiving groove 103 and does not protrude from the surface of the second material guide bar 40 or the cylindrical material guide member 102 at the head of the second material guide bar, thereby preventing interference with the movement of the material. However, when material becomes stuck, the lever 60 moves along the oblong hole 11, exerting a thrust on the stuck bottle, pushing the bottle away and allowing it to re-enter the material guide channel 50, resuming normal conveying.

[0052] In another embodiment, the shift lever 60 may also be configured to be rotatably mounted on the synchronization rod 87 .

[0053] The anti-piling pushing mechanism provided in this embodiment realizes precise control of the material conveying process by arranging a shift rod in the working area to accurately push the material, arranging the driving device outside the working area for easy maintenance, and arranging a bevel surface and a cylindrical material guide at the head of the guide bar to guide the smooth transition of the material; at the same time, the synchronization rod and the driving rod are used to make multiple shift rods move synchronously and expand the working range, and the design of the shift rod passing through the base reduces the impact on the normal conveying of the material, and the limit groove and the oblong hole are used to ensure the stability of the shift rod movement, thereby effectively preventing material accumulation, improving production efficiency, reducing production costs, and having good application prospects.
