Description

Technical Field

[0001] This utility model belongs to the field of nursing product processing technology, specifically relating to an automatic replenishment feeding device for assembling moving blades. Background Technology

[0002] Currently, in the assembly of the cutter head, the moving blades need to be fed into the assembly platform, and the assembly of each component is carried out based on the continuous operation of the robot. However, the moving blades are mainly stacked, that is, the moving blades are stacked on the carrier, and then the carrier automatically fills in the position during the movement of the carrier to form a rapid feeding.

[0003] However, during the feeding process of the carrier, the blade supply channel and the carrier return channel are usually the same channel. Therefore, the previous carrier must be completely withdrawn before the next carrier can be replenished. As a result, the following technical defects exist in actual feeding: The time consumed by the return of the carrier and the replenishment of the fully loaded cutting inserts will cause interruption or time stop in the cutting head assembly, which will not only seriously affect the efficiency of the moving tool assembly, but also increase the probability of the stacked cutting inserts tipping over during the hasty replenishment. Due to the stability of the stack, the number of blades in the resulting stack is relatively low, generally not exceeding 50. If the number of stacked blades is too high, the risk of tipping over will increase. Therefore, frequent replacement operations are required, which further reduces the replacement efficiency of the blades. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an improved automatic replenishment feeding device for moving blade assembly.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An automatic replenishment feeding device for assembling moving blades includes a material rack, a carrier, and a power unit. Two parallel material channels, the first and second, are formed on the material rack. The first material channel is a material preparation channel with inlet and outlet ends, and the second material channel is a material return channel with inlet and outlet ends. A third material channel connects the outlet end of the first material channel and the inlet end of the second material channel, and a replenishment station is connected to the inlet end of the second material channel. The carrier includes a platform and a frame erected on the platform. The platform can move laterally in the first, second and third feed channels, and the frame can automatically fit and pass through the internal space of the cutting blades. Multiple moving blades are stacked on the platform with the frame as a reference. The power unit includes a first, second, and third power unit that moves the platform laterally along the length of the first, second, and third material channels, respectively. The second power unit has two sets: one set located in the second material channel to form a push group, and the other set located in the replenishment station to form a retraction group. Based on the collaborative pushing of the first, second, and third power units, the platform in the preparation channel is moved into the return channel through the third material channel, while the push group pushes the platform to the replenishment station.

[0006] Preferably, the material rack includes a material platform and a baffle disposed on the material platform, wherein a first, second, and third material channel are formed between the baffle and the material platform. The use of an assembled material channel not only facilitates implementation but also allows for adaptive adjustment of the channel width according to the actual dimensions of the platform.

[0007] According to a specific embodiment and preferred aspect of this utility model, the baffle includes first, second, and third side plates arranged side by side; and an end plate forming an end, wherein a first material channel and a second material channel are formed between the first, second, and third side plates; and a third material channel is formed between the second side plate and the end plate to match the transverse movement of the platform. The assembly of the baffle and the end plate forms the required channel and feeding station to facilitate automatic feeding.

[0008] Preferably, the end plate includes a first end body forming the discharge end of the first material channel, and a second end body connecting the first end body to the third side plate and forming a matching platform to constitute a feeding station.

[0009] According to a specific embodiment and preferred aspect of this utility model, one of the stage and the baffle has an inner groove, and the other has a matching outer convex ridge, wherein the movement of the inner groove and the outer convex ridge is matched relative to the lateral movement. In short, the movement guide formed by the inner groove and the outer convex ridge makes the translation of the stage more stable and reduces the overturning rate of stacked blades caused by collisions.

[0010] Preferably, protruding ridges are formed on the inner sides of the first, second, and third side plates, and inner grooves are formed on the opposite sides of each stage. Based on the constraints and guidance at both ends of the stage, misalignment of the stage ends during the flat pushing process is avoided, which not only reduces the probability of stage movement jamming, but also achieves smoother transfer of stacked blades.

[0011] In some specific embodiments, the first power unit includes a first push plate and a first telescopic rod, wherein the first push plate is parallel to the platform, and the extension and retraction of the first telescopic rod causes the first push plate to push the platform horizontally in the first material channel. Here, the platform is smoothly transferred based on parallel pushing.

[0012] Alternatively, the first power unit includes a first push plate and a first telescopic rod, wherein the first push plate is respectively attached to the first material channel from both ends and the bottom, and the opposite ends of the first push plate have notches that match the outward protruding ridge. Here, based on the attachment of the push plate and the motion guidance, not only is the uniformity of the force on the carrier increased during flat pushing to reduce the stacking sway rate caused by impact, but the motion trajectory is also fixed to achieve high-precision transfer and replacement of the carrier platform.

[0013] In some specific embodiments, the pusher assembly includes a second pusher plate and a second telescopic rod, wherein the second pusher plate is parallel to the platform, and the extension and retraction of the second telescopic rod allows the second pusher plate to push the platform horizontally in the second material channel. Here, the platform is smoothly transferred based on parallel pushing.

[0014] Alternatively, the supplementary push assembly includes a second push plate and a second telescopic rod, wherein the second push plate is attached to the second material channel from both ends and the bottom, and the opposite ends of the second push plate have notches that match the outward protruding ridges. Here, based on the push plate attachment and motion guidance, not only is the uniformity of force on the carrier increased during flat pushing to reduce the stacking sway rate caused by impact, but the motion trajectory is also fixed to achieve high-precision transfer and replacement of the carrier platform.

[0015] In some specific embodiments, the retraction assembly includes a third push plate and a third telescopic rod, wherein a channel opening is formed in the second end body, and the third push plate can move in and out of the channel opening to push the platform horizontally towards the return channel. Based on the horizontal pushing of the third push plate, the unloaded platform is retracted towards the retraction channel. At this time, the retraction distance is at least the width of two platforms. Then, after the third push plate is reset, the platform in the material preparation channel can move laterally towards the retraction channel, and then the retraction channel pushes the platform to fill the gap at the material replenishment station.

[0016] In addition, the third power unit is a telescopic rod, and the movement of the telescopic rod will move the platform laterally from the material preparation channel to the return channel along its own length direction.

[0017] Due to the implementation of the above technical solution, this utility model has the following advantages compared with the prior art: In existing stacked blade carrier feeding processes, the time consumed by carrier return and full-load blade replenishment causes interruptions or time stops in blade assembly, severely impacting the efficiency of moving blade assembly and increasing the probability of stacked blade tipping during hasty replenishment. Furthermore, due to the stability of the stack, the number of blades in a stack is relatively low, generally not exceeding 50. Excessive stacking increases the risk of tipping, necessitating frequent replenishment operations, further reducing blade replenishment efficiency. This invention, based on the structure of an automatic replenishment feeding device for moving blade assembly, cleverly solves the shortcomings and defects of existing technologies. Using this automatic replenishment feeding device, the first power unit first moves the material from the preparation channel... The platform loaded with blades is pushed to the discharge end, and then the third power unit pushes the platform horizontally to the return channel. Then, the supplementary pushing group of the second power unit pushes the platform to the replenishment station to complete the automatic replenishment. Therefore, this utility model, on the one hand, is based on the cooperative pushing of the first, second and third power units to put the platform in the preparation channel into the return channel through the third material channel, while the supplementary pushing group pushes the platform to the replenishment station. This not only realizes the automatic replenishment of the platform, but also effectively shortens the replenishment time and improves the blade assembly efficiency. On the other hand, based on the multi-blade moving blades stacked on the platform with the frame rod as the reference, it not only increases the number of stackable blades (more than 4 times that of the original, at least 200 to 300 blades), but also reduces the accidental overturning rate during platform movement.

[0025] like Figures 1 to 5 As shown, the automatic replenishment feeding device for assembling moving blades in this embodiment includes a material rack 1, a carrier 2, and a power unit 3.

[0026] Specifically, the material rack 1 includes a material platform 10 and a baffle 11 disposed on the material platform 10, wherein a first material channel s1, a second material channel s2, and a third material channel s3 are formed between the baffle 11 and the material platform 10. The use of an assembled material channel not only facilitates implementation but also allows for adaptive adjustment of the channel width according to the actual dimensions of the platform. The carrier 2 includes a platform 20 and a support rod 21 erected on the platform 20, wherein the platform 20 can move laterally within the first material channel s1, the second material channel s2, and the third material channel s3, and the support rod 21 can automatically match and pass through the internal space of the cutting blades M. Multiple moving blades M are stacked on the platform with the support rod 21 as a reference. The power unit 3 includes a first power unit 31, a second power unit 32, and a third power unit 33 that move laterally along the length direction of the first material channel s1, the second material channel s2, and the third material channel s3, respectively, to drive the platform 20.

[0027] In some specific embodiments, the material platform 10 is horizontal, and the baffle 11 includes a first side plate 111, a second side plate 112, a third side plate 113 arranged side by side, and an end plate 114 forming the end. A first material channel s1 is formed between the first side plate 111 and the second side plate 112, and a second material channel s2 is formed between the second side plate 112 and the third side plate 113. A third material channel s3 is formed between the second side plate 112 and the end plate 114 to match the transverse movement of the platform. The first material channel s1 is a material preparation channel with inlet and outlet ends, and the second material channel s2 is a material return channel with inlet and outlet ends. The third material channel s3 connects the outlet end of the first material channel s1 and the inlet end of the second material channel s2, and the feeding station is connected to the inlet end of the second material channel s2. The assembly of the baffle and the end plate forms the required channel and feeding station to facilitate automatic feeding. The end plate 114 includes a first end body d1 forming the discharge end of the first material channel s1, and a second end body d2 connecting the first end body d1 to the third side plate 113 and forming a matching platform to constitute a feeding station.

[0028] In this example, protruding ridges t are formed on the inner sides of the first side plate 111, the second side plate 112, and the third side plate 113, respectively, and inner grooves 200 are formed on the opposite sides of each stage 20. Based on the constraints and guidance at both ends of the stage, misalignment of the stage ends during the flat pushing process is avoided, which not only reduces the probability of stage movement jamming, but also achieves smoother transfer of stacked blades.

[0029] In some specific embodiments, the first power unit 31 includes a first push plate 310 and a first telescopic rod 311, wherein the first push plate 310 is parallel to the platform 20, and the extension and retraction of the first telescopic rod 311 causes the first push plate 310 to push the platform 20 horizontally in the first material channel s1. Here, the platform is smoothly transferred based on parallel pushing. Alternatively, the first power unit 31 includes a first push plate 310 and a first telescopic rod 311, wherein the first push plate 310 is attached to the first material channel s1 from both ends and the bottom, and the opposite ends of the first push plate 310 form notches q that match the outward convex ridge t. Here, based on the push plate attachment and motion guidance, not only is the uniformity of force on the frame increased during horizontal pushing to reduce the stacking sway rate caused by impact, but the motion trajectory is also fixed to achieve high-precision transfer and replacement of the platform. The second power unit 32 has two sets, one set located in the second material channel s2 to form a push-back set, and the other set located in the material replenishment station to form a retraction set. Specifically, the supplementary pushing group includes a second push plate 320 and a second telescopic rod 321. The second push plate 320 is parallel to the platform 20, and the extension and retraction of the second telescopic rod 321 allows the second push plate 320 to push the platform 20 horizontally in the second material channel s2. Here, the platform is smoothly transferred based on parallel pushing. Alternatively, the supplementary pushing group includes a second push plate 320 and a second telescopic rod 321. The second push plate 320 is attached to the second material channel s2 from both ends and the bottom, and the opposite ends of the second push plate 320 have notches q that match the outer convex edge t. Here, based on the push plate attachment and motion guidance, not only is the uniformity of force on the carrier increased during horizontal pushing to reduce the stacking sway rate caused by impact, but the motion trajectory is also fixed to achieve high-precision transfer and replacement of the platform. The retraction group includes a third push plate 322 and a third telescopic rod 323. A channel opening is formed in the second end body d2, and the third push plate 322 can enter and exit the channel opening to push the platform 20 horizontally towards the return channel. The third pusher plate pushes the unloaded platform back towards the return channel. The return distance is at least the width of two platforms. After the third pusher plate resets, the platforms in the material preparation channel can move laterally towards the return channel, and then the return channel pushes the platforms to their designated replenishment positions. The third power unit 33 is a telescopic rod, and its movement propels the platform laterally along its length from the material preparation channel to the return channel. In this example, the telescopic rod is an electric cylinder, pneumatic cylinder, or hydraulic cylinder.

[0030] In summary, the automatic platform replacement process in this embodiment is as follows: First, multiple platforms are placed side by side in the material preparation channel (first material channel), and the first power unit pushes them horizontally to the discharge end for transmission. Secondly, the third power unit pushes the platform laterally to the return channel (second material channel); Next, the platform is pushed to the material replenishment station by the second power unit.

[0031] The above steps complete the feeding of a single platform. When continuous feeding is required, the platform is first pushed back by the replenishment push group, and then pushed to the return channel by the return group. The pushing length is at least twice the width of a single platform. Next, the third power unit pushes the automatically replenished platform in the first material channel horizontally to the return channel. At this time, the replenished platform and the returned platform are aligned and fit together. Finally, the second power unit pushes the replenished platform towards the replenishment station, thereby completing the automatic replenishment of the second platform.

[0032] Therefore, with this automatic replenishment feeding device, the first power unit first pushes the platform fully loaded with blades in the preparation channel to the discharge end. Then, the third power unit pushes the platform horizontally to the return channel. Next, the replenishment pushing group of the second power unit pushes the platform to the replenishment station to complete the automatic replenishment. Thus, this invention, on the one hand, is based on the cooperative pushing of the first, second, and third power units, which moves the platform in the preparation channel into the return channel through the third material channel, while the replenishment pushing group pushes the platform to the replenishment station. This not only achieves automatic replenishment of the platform but also effectively shortens the replenishment time, thereby improving the blade assembly efficiency. On the other hand, based on multiple moving blades stacked on the platform with the support rod as the reference, it not only increases the number of stackable blades (more than four times the original) but also reduces the accidental overturning rate during platform movement. Thirdly, the use of an assembled material channel is not only convenient to implement but also allows for adaptive adjustment of the material channel according to the actual size of the platform. The width of the platform is wide, and the assembly of baffles and end plates forms the required channels and replenishment stations to facilitate automatic replenishment. Fourthly, the motion guide formed by the inner groove and outer convex ridge avoids the phenomenon of misalignment of the platform ends during the flat push, which not only reduces the probability of platform movement jamming, but also achieves smoother transfer of stacked blades. Fifthly, the platform is smoothly transferred based on parallel pushing, and based on the push plate fit and motion guide, it not only increases the uniformity of the force on the frame during flat pushing to reduce the stacking sway rate caused by impact, but also fixes the motion trajectory to achieve high-precision transfer and replenishment of the platform. Sixthly, the flat push of the third push plate retracts the unloaded platform to the return channel. At this time, the return distance is at least the width of two platforms. After the third push plate is reset, the platform in the preparation channel can move laterally to the return channel, and then the return channel pushes the platform to the replenishment station.

[0033] The present utility model has been described in detail above, with the aim of enabling those skilled in the art to understand its contents and implement it. However, this description should not be construed as limiting the scope of protection of the present utility model. All equivalent changes or modifications made in accordance with the spirit and essence of the present utility model should be included within the scope of protection of the present utility model.
