Description

Technical Field

[0001] This invention relates to medical devices, and in particular to a feeding device and a medical device production line. Background Technology

[0002] In the automated production of medical devices, the shape of materials is not exactly the same at different locations, and the processing often needs to target specific parts of the material. Therefore, a feeding device is needed to process the materials so that the materials passing through the feeding device maintain the same shape.

[0003] The efficiency of the feeding device is usually matched with the processing efficiency of the subsequent materials. However, in actual production, the efficiency of the feeding device may not match the processing efficiency of the subsequent materials. This is mainly manifested in the feeding device being too efficient, causing material to accumulate on the feeding device. As a result, it is difficult to ensure that the materials passing through the feeding device maintain the same shape, which needs to be improved. Summary of the Invention

[0004] Therefore, it is necessary to provide an improved feeding device and medical device production line. This feeding device can prevent material accumulation, thus ensuring that all materials passing through the feeding device maintain the same shape. Medical device production lines using this feeding device offer stable and reliable production.

[0005] The present invention first provides a feeding device, including a first material tray, the first material tray including a plurality of rejection channels and a plurality of discharge channels, which are arranged perpendicular to the material moving direction. The width of the rejection channels is greater than the width of the discharge channels, and the plurality of rejection channels and the plurality of discharge channels are alternately distributed along the direction perpendicular to the material moving in the first material tray.

[0006] By adopting the above technical solution, when material accumulates in the discharge channel, material entering the first tray cannot enter the discharge channel. The rejection channel is adjacent to the discharge channel, so material that cannot enter the discharge channel will enter the rejection channel. Furthermore, the width of the rejection channel is greater than the width of the discharge channel, causing material entering the rejection channel to fall from the first tray, while material entering the discharge channel will not fall from the discharge channel. Ultimately, when material accumulates in the discharge channel, excess material will leave the first tray through the rejection channel, thus reducing material accumulation in the discharge channel and ensuring that all material passing through the feeding device maintains the same shape.

[0007] In one embodiment of the present invention, the feeding device further includes a second material tray and a guide. The second material tray includes a plurality of feeding channels, and the plurality of feeding channels and the plurality of discharging channels correspond one-to-one. The height of the plurality of feeding channels is higher than the height of the plurality of rejection channels and the plurality of discharging channels. The guide is disposed in the rejection channel and is used to guide the material falling from the feeding channel to the discharging channel.

[0008] By adopting the above technical solution, when there is no material accumulation in the discharge channel, the material falling from the feeding channel moves to the discharge channel and falls there under the guidance of the guide. When there is material accumulation in the discharge channel, the material falling from the feeding channel moves to the discharge channel under the guidance of the guide but cannot fall into the discharge channel. Therefore, the material continues to move to the rejection channel and falls there. The material falling into the rejection channel will then fall from the first material tray. Therefore, the guide can accelerate the accurate and rapid entry of material into the discharge channel when there is no material accumulation, and accelerate the rapid entry of material into the rejection channel when there is material accumulation, thereby reducing the material accumulation in the discharge channel.

[0009] In one embodiment of the present invention, the guide member is provided with a guide surface, which is inclined toward the discharge channel. Material falls from the feeding channel onto the guide surface and moves to the discharge channel under the guidance of the guide surface.

[0010] In one embodiment of the invention, the guiding surfaces of two adjacent guides face the same direction.

[0011] In one embodiment of the present invention, the feeding device further includes a third material tray and a vibrating plate. The discharge port of the vibrating plate is higher than that of the third material tray, and the third material tray is higher than that of the second material tray. The third material tray includes a base plate and multiple partition plates. The lower ends of the multiple partition plates are all connected to the base plate. Multiple primary screening channels are formed between the multiple partition plates and the base plate. The second material tray further includes multiple secondary screening channels. The multiple feeding channels and the multiple secondary screening channels are alternately distributed along a direction perpendicular to the material movement direction. The secondary screening channels are used for material to fall from the second material tray.

[0012] By adopting the above technical solution, when material falls from the discharge port of the vibrating plate to the third tray, materials of a specific shape can enter the primary screening channel, while materials of other shapes cannot enter the primary screening channel and can only remain on the partition plate. When material on the third tray falls to the second tray, material in the primary screening channel can enter the feeding channel, while materials of other shapes remaining on the partition plate may change shape during the fall, thus entering the feeding channel. However, material that still does not conform to the specific shape after falling from the third tray to the second tray cannot enter the feeding channel and will eventually enter the secondary screening channel and leave the second tray. Therefore, the setting of the primary screening channel and the secondary screening channel not only screens materials of a specific shape but also increases the material feeding efficiency.

[0013] In one embodiment of the present invention, the extending direction of the feeding channel is the same as the extending direction of the primary screening channel.

[0014] In one embodiment of the present invention, the feeding device further includes a deweighing component, which overlaps with the first material tray in the height direction. When two materials overlap in the height direction, one of the materials moves along the discharge channel and interferes with the deweighing component.

[0015] By adopting the above technical solution, when two materials in the discharge channel overlap in the height direction, one material, after moving along the discharge channel, interferes with the de-weighting component and cannot continue moving along the discharge channel, while the other material can continue moving along the discharge channel. Therefore, the de-weighting component ensures that the two materials in the discharge channel no longer overlap in the height direction.

[0016] In one embodiment of the present invention, the feeding device further includes a material preparation component, which includes a plurality of material cutting sections. Adjacent material cutting sections form material cutting grooves that correspond one-to-one with the plurality of material discharge channels. When the material preparation component moves along a direction perpendicular to the material's movement on the first material tray, the plurality of material cutting grooves and the plurality of material discharge channels are aligned, or the plurality of material cutting sections and the plurality of material discharge channels are aligned.

[0017] In one embodiment of the present invention, the material preparation assembly further includes a plurality of pushing parts, which are aligned with the plurality of cutting grooves when the plurality of cutting grooves and the plurality of discharge channels are misaligned, and the pushing parts are used to push the material in the corresponding cutting groove out of the cutting groove.

[0018] By adopting the above technical solution, when the material preparation component moves along a direction perpendicular to the material's movement on the first material tray, the multiple cutting troughs and multiple discharge channels change from an aligned state to a misaligned state, and the multiple cutting sections and multiple discharge channels change from a misaligned state to an aligned state. Therefore, the material in the discharge channel is blocked by the cutting section and cannot leave the discharge channel, while a specific amount of material remains in the cutting trough. At this time, the multiple pushing sections and multiple cutting troughs are aligned one by one, thus enabling the material in the cutting trough to be pushed out of the cutting trough. The cooperation of the cutting section and the pushing section enables the removal of a specific amount of material from the discharge channel.

[0019] The present invention also provides a medical device production line, including the above-mentioned feeding device.

[0020] By adopting the above technical solution, the medical device production line using this feeding device can operate stably and reliably. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] It should be noted that when a component is said to be "mounted on" another component, it can be directly mounted on the other component or may be interspersed with a component. When a component is said to be "set on" another component, it can be directly set on the other component or may be interspersed with a component. When a component is said to be "fixed to" another component, it can be directly fixed to the other component or may be interspersed with a component.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] The embodiments of the present invention first provide a feeding device, including a vibratory plate 100, a first material tray 200, a second material tray 300, a third material tray 400, a guide 500, a weight removal component 600, and a material preparation assembly 700.

[0032] The discharge port of the vibratory feeder 100 is higher than the third feed plate 400, the third feed plate 400 is higher than the second feed plate 300, and the second feed plate 300 is higher than the first feed plate 200. Therefore, the discharge port of the vibratory feeder 100, the third feed plate 400, the second feed plate 300 and the first feed plate 200 show a trend of decreasing height.

[0033] The third material tray 400 includes a base plate 410 and multiple partition plates 420. The lower ends of the multiple partition plates 420 are all connected to the base plate 410. Multiple primary screening channels 430 are formed between the multiple partition plates 420 and the base plate 410.

[0034] The second material tray 300 includes multiple feeding channels 310 and multiple secondary screening channels 320. The feeding channels 310 and secondary screening channels 320 are alternately distributed along a direction perpendicular to the material movement direction. The feeding channels 310 are used to convey material, and the secondary screening channels 320 have open bottoms, allowing material passing through them to fall from the second material tray 300. The extending direction of the feeding channels 310 is the same as that of the primary screening channels 430. The heights of the feeding channels 310 and the secondary screening channels 320 are both lower than the heights of the primary screening channels 430.

[0035] When material falls from the discharge port of vibrating plate 100 to the third tray 400, materials of a specific shape can enter the primary screening channel 430, while materials of other shapes cannot enter the primary screening channel and can only remain on the partition plate 420. When material on the third tray 400 falls to the second tray 300, material in the primary screening channel can enter the feeding channel 310. At the same time, materials of other shapes remaining on the partition plate 420 may change shape during the fall, thus being able to enter the feeding channel 310. However, material that still does not conform to the specific shape after falling from the third tray 400 to the second tray 300 cannot enter the feeding channel 310 and will eventually enter the secondary screening channel 320 and leave the second tray 300. Therefore, the primary screening channel 430 and the secondary screening channel are designed to both screen materials of a specific shape and increase material feeding efficiency.

[0036] The first material tray 200 includes multiple rejection channels 210 and multiple discharge channels 220. The rejection channels 210 and discharge channels 220 are alternately distributed along a direction perpendicular to the material's movement in the first material tray 200. Along this direction, the width of the rejection channels 210 is greater than the width of the discharge channels 220. The bottom of the rejection channels 210 is open, allowing material entering the rejection channels 210 to fall from the first material tray 200. The bottom of the discharge channels 220 is also open, allowing material entering the discharge channels 220 to change from a horizontal to a vertical position. The multiple discharge channels 220 correspond one-to-one with the multiple feeding channels 310. The heights of both the rejection channels 210 and the discharge channels 220 are lower than the heights of the feeding channels 310.

[0037] A guide member 500 is disposed at one end of the rejection channel 210 near the second material tray 300. The guide member 500 guides the material falling from the feeding channel 310 to the discharge channel 220. The guide member 500 is provided with a guiding surface, which is inclined towards the discharge channel 220, and the guiding surfaces of two adjacent guide members 500 have the same orientation. The material falls from the feeding channel 310 onto the guiding surface and moves to the discharge channel 220 under the guidance of the guiding surface.

[0038] When material accumulates in the discharge channel 220, material entering the first tray 200 cannot enter the discharge channel 220. The rejection channel is adjacent to the discharge channel, so material unable to enter the discharge channel 220 will enter the rejection channel. Since the width of the rejection channel 210 is greater than the width of the discharge channel 220, material entering the rejection channel 210 will fall from the first tray 200, while material entering the discharge channel 220 will not fall from the discharge channel 220. Ultimately, when material accumulates in the discharge channel 220, excess material will leave the first tray 200 through the rejection channel, thus alleviating the accumulation in the discharge channel 220 and ensuring that all material passing through the feeding device maintains the same shape.

[0039] When there is no material accumulation in the discharge channel 220, the material falling from the feeding channel 310 moves to the discharge channel and falls there under the guidance of the guide 500. When there is material accumulation in the discharge channel 220, the material falling from the feeding channel 310 moves to the discharge channel under the guidance of the guide 500 but cannot fall there. Therefore, the material continues to move to the rejection channel 210 and falls there. The material falling into the rejection channel 210 will then fall from the first tray 200. Therefore, the guide 500 can accelerate the accurate and rapid entry of material into the discharge channel 220 when there is no material accumulation, and accelerate the rapid entry of material into the rejection channel 210 when there is material accumulation, thereby reducing the material accumulation in the discharge channel 220.

[0040] The deweighting component 600 and a portion of the first material tray 200 overlap in the height direction. Guide members and the deweighting component 600 are spaced apart along the material's movement direction in the first material tray 200. When two materials in the discharge channel overlap in the height direction, one material, after moving along the discharge channel 220, interferes with the deweighting component 600 and cannot continue moving along the discharge channel, while the other material can continue moving along the discharge channel 220. Therefore, the deweighting component 600 prevents the two materials in the discharge channel from overlapping in the height direction.

[0041] The material preparation assembly 700 includes a cutting component 710, a pushing component 720, a cutting drive component 730, a pushing drive component 740, and a material preparation component 750.

[0042] The material cutter 710 is located at the end of the first material tray 200 away from the second material tray 300. The material cutter 710 includes multiple material cutters 711 and a material cutter connecting portion 712 connecting the multiple material cutters 711. Material cutter grooves 713 are formed between adjacent material cutters 711, corresponding one-to-one with the multiple discharge channels 220. The material cutter drive 730 drives the material cutter connecting portion 712 to move the material cutters 711. When the material cutters 711 move along a direction perpendicular to the material's movement in the first material tray 200, the multiple material cutter grooves 713 and the multiple discharge channels 220 are aligned, or the multiple material cutters 711 and the multiple discharge channels 220 are aligned. When the multiple material cutter grooves 713 and the multiple discharge channels 220 are aligned, the multiple material cutters 711 and the waste removal channels are aligned.

[0043] The pusher 720 includes multiple pusher sections 721 and pusher connecting sections 722 connecting the multiple pusher sections 721. The multiple pusher sections 721 are located in different scrap rejection channels and are located near the end of the scrap rejection channel away from the second material tray 300. The pusher drive 740 drives the pusher connecting section 722 to move the pusher sections 721. When the multiple cutting sections 711 and the multiple discharge channels 220 are aligned, the multiple cutting grooves 713 and the multiple discharge channels 220 are misaligned and aligned one by one with the multiple pusher sections 721 located in the scrap rejection channel. At this time, the pusher drive 740 drives the pusher sections 721 to act on the material in the cutting groove 713, pushing the material in the cutting groove 713 out of the cutting groove 713.

[0044] The material preparation component 750 is located on the side of the material cutting component 710 opposite to the material pushing component 720. The material preparation component 750 includes multiple limiting parts 751 and a supporting part 752. The multiple limiting parts 751 are connected to the upper surface of the supporting part 752. The multiple limiting parts 751 correspond one-to-one with the multiple discharge channels 220, and a limiting channel 753 is formed between two adjacent limiting parts 751. When the multiple cutting parts 711 and the multiple discharge channels 220 are aligned, the multiple cutting grooves 713 and the multiple discharge channels 220 are misaligned and aligned one-to-one with the limiting channel 753. The upper surface of the supporting part 752 and the bottom of the cutting groove 713 are as flush as possible. After the material is pushed out of the cutting groove 713 by the material pushing part 721, the material moves onto the supporting part 752 after passing through the limiting channel 753.

[0045] The working process of the feeding device is as follows:

[0046] The material falls from the discharge port of the vibrating plate 100 to the third material tray 400. Material in a specific shape enters the primary screening channel 430, while material in other shapes is located on the partition plate 420.

[0047] Material falls from the third material tray 400 onto the second material tray 300. Material in the primary screening channel 430 enters the feeding channel 310. Material in other forms will transform into a specific form during the falling process and thus enter the feeding channel 310. Material that still does not conform to the specific form cannot enter the feeding channel 310 and will eventually enter the secondary screening channel 320 and leave the second material channel.

[0048] Material falls from the second tray 300 onto the third tray 400, and is guided by the guide 500 into the discharge channel 220. When accumulation occurs in the discharge channel 220, the material, guided by the guide 500, cannot enter the discharge channel 220 and instead enters the rejection channel 210, eventually leaving the first channel.

[0049] After leaving the discharge channel 220, the material enters the intercepting trough 713. The intercepting drive 730 drives the intercepting connector 712 to move the intercepting part 711, causing the multiple intercepting troughs 713 and the multiple discharge channels 220 to change from an aligned state to a misaligned state, and the multiple intercepting parts 711 and the multiple discharge channels 220 to change from a misaligned state to an aligned state. At this time, the material in the discharge channel 220 is blocked by the intercepting part 711 and can no longer leave the discharge channel 220.

[0050] The pusher drive 740 drives the pusher connection 722 to move the pusher 721, so that the pusher 721 acts on the material in the cutting groove 713 and pushes the material out of the cutting groove 713. The material leaving the cutting groove 713 then moves to the bearing part 752 after passing through the limiting channel 753.
