Description

Technical Field

[0001] This invention relates to the field of food and pharmaceutical packaging machinery and equipment, specifically to an article rotating device, a conveying system, and a conveying method. Background Technology

[0002] An existing application (application number 202122083946.7) describes a bottle washing machine's tilting device. A cam follower moves along a cam track, and through a specific track curve, the cam follower moves up and down along the cam track, causing a swing arm to oscillate in a vertical plane. The swing arm's oscillation drives a second gear to rotate, which in turn drives a first gear, causing a robotic arm to rotate and thus tilting the bottle held by the robotic arm 180°. However, this tilting device tilts all bottles it passes through, preventing selective tilting. It only allows bottles that need to be tilted to pass through, which is detrimental to continuous bottle transport and affects transport efficiency.

[0003] Existing bottle conveying systems generally include a vibrating feeding device and a bottle conveying device. The bottle outlet of the vibrating feeding device is directly connected to the bottle conveying device, which outputs the bottle after feeding to the bottle conveying device. On the one hand, the vibrating feeding device cannot guarantee that all bottles are output upright or upside down; on the other hand, upright and upside down bottles must be conveyed along separate paths, resulting in low conveying efficiency. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide an article rotation device, conveying system and conveying method that meets the selective rotation requirements of articles, allows all articles to pass through, facilitates continuous article conveying, and improves article conveying efficiency.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An item rotation device includes a rotation mechanism, a pick-and-place mechanism, a guide rail, multiple reciprocating moving blocks, and an adjustment mechanism. Each of the pick-and-place mechanisms is evenly distributed on the rotation mechanism. The reciprocating moving blocks are disposed on the rotation mechanism and can move along the guide rail. The reciprocating moving blocks are correspondingly connected to the pick-and-place mechanisms to drive the pick-and-place mechanisms to rotate. The guide rail is provided with a docking section. The docking section is provided with at least a first track and a second track. The adjustment mechanism is connected to the docking section and is used to switch the first track or the second track to dock with the guide rail, thereby changing the running trajectory of the reciprocating moving blocks and driving the pick-and-place mechanism to rotate.

[0006] As a further improvement to the above technical solution: The reciprocating moving block is equipped with rollers and an elastic reset component is provided between it and the rotating mechanism. The reciprocating moving block is in rolling cooperation with the guide rail through the rollers.

[0007] The reciprocating moving block is provided with a rack, and the picking and placing mechanism is provided with a gear, and the rack and the gear mesh.

[0008] The rotating mechanism includes a rotating disk and a rotating drive assembly for driving the rotating disk to rotate. The pick-and-place mechanism is located on the periphery of the rotating disk, and the reciprocating moving block is located on the rotating disk.

[0009] The rotating disk is arranged horizontally, the reciprocating moving block reciprocates in the vertical direction, and the guide rail is fixed below the rotating disk.

[0010] The rotating device is used to flip the bottle. The rotating mechanism is a circulating conveying mechanism. Multiple picking and placing mechanisms are provided for picking and placing the bottle. Each picking and placing mechanism is arranged at intervals along the conveying direction of the circulating conveying mechanism. The first track is used to translate the bottle. The second track is used to push the reciprocating moving block to drive the picking and placing mechanism to rotate and flip the bottle.

[0011] An item conveying system includes an item handling device, a conveying channel, a standing channel, an item receiving and delivery mechanism, and the aforementioned item rotating device. One end of the conveying channel is connected to the outlet of the item handling device, and the other end is connected to the upper inlet of the standing channel. The item receiving and delivery mechanism is used to receive items at the lower outlet of the standing channel and convey the items to the retrieval point of the item rotating device's pick-up and drop-off mechanism.

[0012] As a further improvement to the above technical solution: The receiving and feeding mechanism includes a receiving seat and a reciprocating drive mechanism. The reciprocating drive mechanism is used to drive the receiving seat to move back and forth between the vertical channel outlet and the rotating mechanism. The receiving seat is provided with a bearing surface for bearing items. The bearing surface is provided with a groove. The groove is smaller than the bottom of the item and larger than the top of the item. The side of the groove facing the feeding direction is open to form an outlet.

[0013] The receiving base is provided with a first orientation detection mechanism for detecting the orientation of an item and a positioning detection mechanism for detecting whether an inverted item is inserted into a predetermined position in the groove. The corresponding position of the docking section is provided with a second orientation detection mechanism for detecting the orientation of an item and an inverted item collection mechanism. The first orientation detection mechanism and the positioning detection mechanism are signal-connected to the adjustment mechanism, and the second orientation detection mechanism is signal-connected to the pick-up and put-down mechanism.

[0014] A method for conveying goods, using the aforementioned goods conveying system, includes the following steps: S1. Conveying Items: After being sorted by the material handling equipment, the items are conveyed sequentially along the conveyor channel and the vertical material channel; S2, Item receiving: The bearing surface of the receiving seat is located below the vertical channel to receive items; S3. Determine the orientation of the item: If the first orientation detection mechanism detects that the item is inverted, and the positioning detection mechanism detects that the inverted item is inserted into the predetermined position in the groove, then it is determined that the item needs to be flipped, and the adjustment mechanism receives a signal to make the second track connect with the guide rail; otherwise, it is determined that the item does not need to be flipped, and the adjustment mechanism receives a signal to make the first track connect with the guide rail. S4. Pushing items: The reciprocating drive mechanism drives the receiving seat to push the items to the picking and placing mechanism. S5. Selective item flipping: The pick-up and place mechanism picks up the item and moves with the rotating mechanism. At the same time, the reciprocating block corresponding to the pick-up and place mechanism moves along the guide rail. If the reciprocating block passes through the first track, the pick-up and place mechanism does not rotate and flip the item. If the reciprocating block passes through the second track, the reciprocating block drives the pick-up and place mechanism to rotate and flip the item. S6. Re-determine the orientation of the item: The second orientation detection mechanism detects the orientation of the item after it has passed through the docking section. If the item is upside down, the corresponding pick-up and drop mechanism releases the item and collects it into the inverted collection mechanism. Otherwise, the item continues to be transported backward.

[0015] Compared with the prior art, the advantages of the present invention are as follows: In this invention, the rotating device for handling items involves a pick-and-place mechanism that grips or sucks up items, rotating along with the rotating mechanism. A reciprocating block also rotates with the rotating mechanism and moves along a guide rail. When the item needs to be rotated and reversed, an adjustment mechanism aligns the second track of the docking section with the guide rail. This changes the trajectory of the reciprocating block as it passes the second track, thus driving the pick-and-place mechanism to rotate and reverse the item. When the item does not need to be rotated and reversed, the adjustment mechanism aligns the first track of the docking section with the guide rail. This prevents the reciprocating block from changing its trajectory when it passes the first track, thus not driving the pick-and-place mechanism to rotate and reverse the item. When used to flip bottles, this rotating device can switch between the first and second tracks and the guide rail, allowing selective docking of the guide rail with either track. This satisfies the selective flipping requirements of bottles, allowing all bottles to pass through, facilitating continuous bottle transport and improving transport efficiency. This rotating device satisfies the selective rotation requirements of items, allowing all items to pass through, facilitating continuous transport and improving transport efficiency.

[0016] The article conveying system of the present invention, on the one hand, since the sorting device and conveying channel cannot guarantee that all articles are output upright or upside down, by combining the upright channel and the selective docking of the docking section, it is further guaranteed that all articles are output upright or upside down; on the other hand, both upright and upside down articles are conveyed by guide rails, which is relatively separate path conveying, and the conveying efficiency is high.

[0017] The article conveying method of the present invention, on the one hand, further ensures that all articles are output upright or upside down by combining the selective docking of the upright channel and the docking section; on the other hand, both upright and upside down articles are conveyed through the guide rail, which is relatively separate path conveying and has high conveying efficiency; thirdly, through the cooperation of various detection mechanisms and their adjustment mechanisms, it is easy to accurately control the lifting and lowering of the docking section, accurately switch the first track and the second track to dock with the guide rail, so that the articles that continue to be conveyed through the guide rail are all in an upright state.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] In the description of this invention, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0032] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "assembly," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] Example 1: Figures 1 to 5An embodiment of the article rotating device of the present invention is shown. The article rotating device of this embodiment includes a rotating mechanism 1, a pick-and-place mechanism 2, a guide rail 3, a plurality of reciprocating moving blocks 4, and an adjustment mechanism 5. Each pick-and-place mechanism 2 is evenly distributed on the rotating mechanism 1. The reciprocating moving blocks 4 are disposed on the rotating mechanism 1 and can move along the guide rail 3. The reciprocating moving blocks 4 are correspondingly connected to the pick-and-place mechanisms 2 and are used to drive the pick-and-place mechanisms 2 to rotate. The guide rail 3 is provided with a docking section 31. The docking section 31 is provided with at least a first track 311 and a second track 312. The adjustment mechanism 5 is connected to the docking section 31 and is used to switch the first track 311 or the second track 312 to dock with the guide rail 3, so that the running trajectory of the reciprocating moving blocks 4 changes, thereby driving the pick-and-place mechanism 2 to rotate.

[0035] In use, the pick-and-place mechanism 2 grips or picks up items as the rotating mechanism 1 rotates, and the reciprocating moving block 4 also rotates with the rotating mechanism 1 and moves along the guide rail 3. When the items need to be rotated or reversed, the adjustment mechanism 5 aligns the second track 312 of the docking section 31 with the guide rail 3 (e.g., ...). Figure 1 As shown, when the reciprocating block 4 passes the second track 312, its trajectory changes, driving the pick-and-place mechanism 2 to rotate and change the direction of the item. When the item does not need to rotate and change direction, the adjustment mechanism 5 aligns the first track 311 of the docking section 31 with the guide rail 3. Thus, when the reciprocating block 4 passes the first track 311, its trajectory does not change, and the pick-and-place mechanism 2 is not driven to rotate and change direction. When this item rotation device is used to flip bottles, it can switch the docking of the first track 311 and the second track 312 with the guide rail 3, allowing the guide rail 3 to selectively dock with either the first track 311 or the second track 312. This satisfies the selective flipping requirements of the bottle, allowing all bottles to pass through, facilitating continuous bottle transport and improving bottle transport efficiency. This item rotation device satisfies the selective rotation requirements of the item, allowing all items to pass through, facilitating continuous item transport and improving item transport efficiency.

[0036] Furthermore, in this embodiment, the reciprocating moving block 4 is provided with a roller 41 and an elastic reset member 43 is provided between it and the rotating mechanism 1. The reciprocating moving block 4 rolls with the guide rail 3 through the roller 41. Under the elastic force of the elastic reset member 43, the reciprocating moving block 4 rolls with the guide rail 3 through the roller 41, reducing friction with the guide rail 3 and improving movement stability.

[0037] Furthermore, in this embodiment, the reciprocating moving block 4 is provided with a rack 42, and the pick-and-place mechanism 2 is provided with a gear 21, with the rack 42 and gear 21 meshing together. The reciprocating motion of the reciprocating moving block 4 causes the pick-and-place mechanism 2 to rotate through the transmission action of the rack 42 and gear 21.

[0038] Furthermore, in this embodiment, the rotating mechanism 1 includes a rotating disk 11 and a rotating drive assembly 12 for driving the rotating disk 11 to rotate. The pick-and-place mechanism 2 is disposed on the periphery of the rotating disk 11, and the reciprocating moving block 4 is disposed on the rotating disk 11. The rotating drive assembly 12 drives the rotating disk 11 to rotate, and the pick-and-place mechanism 2 and the reciprocating moving block 4 rotate with the rotating mechanism 1.

[0039] Furthermore, in this embodiment, the rotating disk 11 is arranged horizontally, the reciprocating block 4 reciprocates vertically, and the guide rail 3 is fixed below the rotating disk 11. The rotating disk 11 is arranged horizontally, that is, the rotation axis of the rotating disk 11 is arranged vertically. Of course, the position and orientation of the rotating disk 11 can be arranged as needed, as long as the rotation axis of the rotating disk 11 and the reciprocating direction of the reciprocating block 4 are parallel.

[0040] Furthermore, in this embodiment, the item rotation device is used to flip the bottle, the rotation mechanism 1 is a circulating conveying mechanism, and multiple pick-and-place mechanisms 2 are provided for picking up and placing the bottle. Each pick-and-place mechanism 2 is arranged at intervals along the conveying direction of the circulating conveying mechanism. The first track 311 is used to make the bottle translate, and the second track 312 is used to push the reciprocating moving block 4 to drive the pick-and-place mechanism 2 to rotate to flip the bottle.

[0041] Example 2: Figures 6 to 11 An embodiment of the article conveying system of the present invention is shown. The article conveying system of this embodiment includes a sorting device 6, a conveying channel 61, a standing channel 7, a receiving and delivering mechanism 8, and an article rotating device of Embodiment 1. One end of the conveying channel 61 is connected to the outlet of the sorting device 6, and the other end is connected to the upper inlet of the standing channel 7. The receiving and delivering mechanism 8 is used to receive articles at the lower outlet of the standing channel 7 and convey the articles to the picking and placing mechanism 2 of the article rotating device.

[0042] The production process of this material conveying system is as follows: First, the materials sorted by the material handling device 6 are conveyed sequentially along the conveying channel 61 and the standing channel 7; Second, the receiving and feeding mechanism 8 receives the materials below the standing channel 7; Third, the orientation of the materials is determined. If the materials are inverted and inserted into a predetermined position on the receiving and feeding mechanism 8, it is determined that the materials need to be flipped, and the adjusting mechanism 5 aligns the second track 312 with the guide rail 3; otherwise, it is determined that the materials do not need to be flipped, and the adjusting mechanism 5 aligns the first track 311 with the guide rail 3; Fourth, the receiving and feeding mechanism 8 pushes the materials to the picking and placing mechanism 2; Fifth, the picking and placing mechanism 2 picks up the materials and moves with the rotating mechanism 1. At the same time, the reciprocating block 4 corresponding to the picking and placing mechanism 2 moves along the guide rail 3; If the reciprocating block 4 passes the first track 311, the picking and placing mechanism 2 does not rotate and flip the materials; if the reciprocating block 4 passes the second track 312, the reciprocating block 4 drives the picking and placing mechanism 2 to rotate and flip the materials; Sixth step... On the one hand, since the material handling device 6 and the conveying channel 61 cannot guarantee that all items are output upright or upside down, the combination of selective docking of the upright channel 7 and the docking section 31 further ensures that all items are output upright or upside down; on the other hand, both upright and upside down items are conveyed through the guide rail 3, which is relatively separate path conveying and has high conveying efficiency.

[0043] Furthermore, this material conveying system is used for conveying bottles, ensuring that all bottles are output upright or upside down, eliminating unnecessary separate paths for upright and upside-down conveying, and improving conveying efficiency.

[0044] Furthermore, in this embodiment, the receiving and feeding mechanism 8 includes a receiving seat 81 and a reciprocating drive mechanism 82. The reciprocating drive mechanism 82 is used to drive the receiving seat 81 to reciprocate between the outlet of the standing channel 7 and the rotating mechanism 1. The receiving seat 81 is provided with a bearing surface 811 for bearing items (e.g., ...). Figure 11 As shown in Figure b), a groove 812 is provided on the bearing surface 811. The groove 812 is smaller than the bottom of the item and larger than the top of the item. The side of the groove 812 facing the feeding direction opens to form an outlet 813. The outlet 813 facilitates the horizontal movement of the item. In use, the bearing surface 811 is arranged horizontally. When an item (such as a bottle) falls upright onto the receiving base 81, because the groove 812 is smaller than the bottom of the item, the bottom of the item will be supported on the bearing surface 811. When an item (such as a bottle) falls upside down onto the receiving base 81, because the groove 812 is larger than the top of the item, the top of the item may insert into the groove 812 (e.g., the bottom of the bottle). Figure 11 (As shown in Figure a), or the top surface of the item may be supported on the bearing surface 811 (e.g. Figure 11As shown in Figure c), the upright and inverted states of an object can be determined by detecting its height. If the height of the object is lower than the normal height (the height at which the object is supported on the bearing surface 811), the object is inverted; otherwise, it may be upright or inverted. In summary, by providing a groove 812 on the bearing surface 811, it is easier to more accurately detect the upright and inverted states (positive and negative states) of an object.

[0045] Furthermore, in this embodiment, the receiving base 81 is provided with a first positive / negative detection mechanism 814 for detecting the positive / negative state of an item and a positioning detection mechanism 815 for detecting whether an inverted item is inserted into a predetermined position in the groove 812. The receiving section 31 is provided with a second positive / negative detection mechanism 9 for detecting the positive / negative state of an item and an inverted item collection mechanism. The first positive / negative detection mechanism 814 and the positioning detection mechanism 815 are signal-connected to the adjustment mechanism 5, and the second positive / negative detection mechanism 9 is signal-connected to the pick-and-place mechanism 2.

[0046] Determining the orientation of an item: If the first orientation detection mechanism 814 detects that the item is upside down, and the positioning detection mechanism 815 detects that the upside-down item is inserted into the predetermined position in the groove 812, then it is determined that the item needs to be flipped. The adjustment mechanism 5 receives a signal to align the second track 312 with the guide rail 3. Otherwise, it is determined that the item does not need to be flipped, and the adjustment mechanism 5 receives a signal to align the first track 311 with the guide rail 3. The second orientation detection mechanism 9 detects the status of the item after passing through the docking section 31. If the item is upside down, the corresponding pick-up and drop mechanism 2 releases the item, allowing it to be collected into the item collection mechanism. Otherwise, the item continues to be conveyed backward. In this way, through the cooperation of each detection mechanism and the adjustment mechanism 5, the lifting and lowering of the docking section 31 can be accurately controlled, and the first track 311 and the second track 312 can be accurately switched to align with the guide rail 3, so that all items conveyed backward after passing through the guide rail 3 are in an upright position.

[0047] Furthermore, the second forward / reverse detection mechanism 9 includes a bottle-tipping detection component 91 and a bottle-reversing detection component 12, both of which are signal-connected to the pick-and-place mechanism 2. In addition, to ensure that all bottles output from the bottle sorting process have their openings facing upwards, bottle-tipping detection components 91 and 12 are installed after the bottle is flipped. Both are signal-connected to the pick-and-place mechanism 2. The bottle-tipping detection component 91 detects the lower edge of the bottle. If the bottle opening is downwards (due to improper flipping or incorrect flipping, the lower edge will be below the bottom of the bottle), the detection switch illuminates, the pick-and-place mechanism 2 releases, the bottle falls, and the waste is removed. The bottle-reversing detection component 12 detects the edge of the bottle opening. If a reversed bottle fails to fall completely into the groove 812, it is mistakenly detected as a normal bottle. Figure 11As shown in Figure c, the bottle is now facing upwards with its top dimension larger than the normal bottle opening size. The switch is lit, and the pick-and-place mechanism 2 is released, causing the bottle to fall and complete the rejection. This ensures that all bottles output to subsequent workstations are in an upright position with their openings facing upwards.

[0048] Example 3: A bottle conveying method, using the article conveying system of Embodiment 2, includes the following steps: S1. Conveying items: The items sorted by the material handling device 6 are conveyed sequentially along the conveyor channel 61 and the vertical material channel 7; S2, receiving items: The bearing surface 811 of the receiving seat 81 receives items below the vertical channel 7; S3. Determine the orientation of the item: If the first orientation detection mechanism 814 detects that the item is inverted and the positioning detection mechanism 815 detects that the inverted item is inserted into the predetermined position in the groove 812, then it is determined that the item needs to be flipped, and the adjustment mechanism 5 receives a signal to make the second track 312 dock with the guide rail 3; otherwise, it is determined that the item does not need to be flipped, and the adjustment mechanism 5 receives a signal to make the first track 311 dock with the guide rail 3. S4. Pushing items: The reciprocating drive mechanism 82 drives the receiving seat 81 to push the items to the picking point of the picking and placing mechanism 2. S5. Selective flipping of items: The pick-up and place mechanism 2 picks up the items and moves with the rotating mechanism 1. At the same time, the reciprocating block 4 corresponding to the pick-up and place mechanism 2 moves along the guide rail 3. If the reciprocating block 4 passes through the first track 311, the pick-up and place mechanism 2 does not rotate and flip the items. If the reciprocating block 4 passes through the second track 312, the reciprocating block 4 drives the pick-up and place mechanism 2 to rotate and flip the items. S6. Re-determine the orientation of the item: The second orientation detection mechanism 9 detects the orientation of the item after passing through the docking section 31. If the item is upside down, the corresponding pick-up and drop mechanism 2 releases the item so that it is collected into the inverted collection mechanism. Otherwise, the item continues to be transported backward.

[0049] This bottle conveying method, on the one hand, further ensures that all items are output upright or upside down through the selective docking of the upright channel 7 and the docking section 31; on the other hand, both upright and upside down items are conveyed via the guide rail 3, which is relatively separate path conveying and has high conveying efficiency; thirdly, through the cooperation of various detection mechanisms and their adjustment mechanisms 5, it is easy to accurately control the lifting and lowering of the docking section 31, accurately switch the first track 311 and the second track 312 to dock with the guide rail 3, so that the items that continue to be conveyed through the guide rail 3 are all in an upright state.

[0050] Furthermore, this bottle conveying method is used to convey bottles. After being processed by the material handling device 6, the bottles are conveyed sequentially along the conveying channel 61 and the standing channel 7. The bearing surface 811 of the receiving seat 81 receives the bottle below the standing channel 7. The bottle's orientation is determined. If the first orientation detection mechanism 814 detects that the bottle is inverted, and the positioning detection mechanism 815 detects that the inverted bottle is inserted into the predetermined position in the groove 812, then it is determined that the bottle needs to be flipped. The adjustment mechanism 5 receives a signal to align the second track 312 with the guide rail 3. Otherwise, it is determined that the bottle does not need to be flipped. The adjustment mechanism 5 receives a signal to align the first track 311 with the guide rail 3. The reciprocating drive mechanism 82 drives the receiving seat 81 to deliver the bottle to the bottle pick-up point of the pick-up and place mechanism 2. The pick-up and place mechanism 2 picks up the bottle and moves with the bottle conveying mechanism 1. At the same time, the reciprocating moving block 4 corresponding to the pick-up and place mechanism 2 moves along the guide rail 3. If the reciprocating moving block 4 passes through the first track 311, the pick-up and place mechanism 2 does not rotate to flip the bottle. If the reciprocating moving block 4 passes through the second track 312, the reciprocating moving block 4 drives the pick-up and place mechanism 2 to rotate and flip the bottle. The second forward and reverse detection mechanism 9 detects the state of the bottle after passing through the docking section 31. If the bottle is inverted, the corresponding pick-up and place mechanism 2 puts the bottle down so that the bottle is collected in the bottle collection mechanism. Otherwise, the bottle continues to be conveyed backward.
