Description

Technical Field

[0001] This application relates to the field of liquor production technology, and in particular to a flipping mechanism and a steamer lifting and flipping device. Background Technology

[0002] In the field of baijiu production technology, when producing certain types of baijiu, all grains such as corn and sorghum need to be steamed before fermentation. This is to kill off-flavors in the raw materials through high-temperature steaming and to volatilize off-flavor substances (such as methanol produced by the decomposition of pectin in sorghum), thus ensuring the purity of the liquor.

[0003] In related technologies, the grain needs to be transferred to a steamer basket, and then the basket is moved to the steaming area by a forklift or overhead crane for steaming. After steaming, the basket is moved to the cooling area and the grain is removed and cooled manually. However, this method is inefficient. Summary of the Invention

[0004] This application provides a flipping mechanism and a steamer tray lifting and flipping device to improve the transfer efficiency of the steamer tray and grain.

[0005] In a first aspect, embodiments of this application provide a flipping mechanism, including:

[0006] Support;

[0007] A drive motor is connected to the support.

[0008] A limiting member is fixedly connected to the support, and the limiting member has a mating hole along its axial direction;

[0009] A flipping component is rotatably disposed within the mating hole. The flipping component is connected to the drive motor. The flipping component is provided with a mating groove for connecting with the item to be flipped.

[0010] The drive motor selectively drives the flipping component to rotate, thereby causing the item to be flipped to rotate.

[0011] In one feasible implementation, the side wall of the limiting member is provided with an opening, the mating groove is provided on the side wall of the flipping member, and the item to be flipped enters the mating hole through the opening and connects with the mating groove.

[0012] In one feasible implementation, the cross-section of the opening on the side wall of the limiting member and the cross-section of the mating groove are both straight or V-shaped.

[0013] In one feasible implementation, the opening on the side wall of the limiting member faces vertically upward, and when the flipping member is in the initial position, the opening of the mating groove faces upward and corresponds to the opening on the side wall of the limiting member.

[0014] In one feasible implementation, a positioning stop is provided on the inner side of the mating groove in the axial direction. The positioning stop is an inclined structure facing the opening direction of the mating groove.

[0015] In one feasible implementation, the flipping mechanism further includes an arrival detection component disposed on the limiting member, the arrival detection component being used to detect whether the part to be flipped has passed through the opening and has completed the engagement with the mating groove;

[0016] Alternatively, the positioning detection component may be configured as a photoelectric detection sensor.

[0017] In one feasible implementation, a wear-resistant pad is disposed between the flipping member and the limiting member.

[0018] In one feasible implementation, the flipping mechanism further includes a speed reducer, through which the drive motor is connected to the flipping component.

[0019] Secondly, embodiments of this application provide a steamer tray lifting and turning device, including a lifting mechanism, a traveling mechanism, and a turning mechanism as described in the first aspect;

[0020] The traveling mechanism is located at the bottom of the lifting mechanism. The lifting mechanism includes forks for fixing the steamer tray. The lifting mechanism is used to raise and lower the steamer tray. The traveling mechanism drives the lifting mechanism to move in order to transfer the steamer tray.

[0021] The flipping mechanism is mounted on the forks, and the handle of the steamer is connected to the flipping mechanism. The flipping mechanism is used to flip the steamer.

[0022] In one feasible implementation, the steamer basket lifting and tilting device further includes an extension fork detection component and / or a steamer basket status monitoring component;

[0023] The fork extension detection component is used to detect whether the flipping mechanism corresponds to the handle of the steamer when the forks are extended. The fork extension detection component includes at least two photoelectric detection sensors arranged on the forks. The at least two photoelectric detection sensors are respectively arranged on both sides of the flipping mechanism. When the handle of the steamer is not fully aligned with the flipping mechanism, the handle of the steamer triggers the photoelectric detection sensor located on the front or rear side of the flipping mechanism.

[0024] The steamer status monitoring component is used to monitor the status of the steamer. The steamer status monitoring component includes at least two sets of photoelectric detection sensors installed on the forks. At least two photoelectric detection sensors are installed on the front and rear sides below the steamer. When the steamer tilts forward or backward, the steamer triggers the photoelectric detection sensors located on the front or rear side of the steamer.

[0025] In one feasible implementation, the steamer status monitoring component further includes a proximity detection element, which is disposed at the front end of the loading platform. The proximity detection element is positioned at a height lower than the horizontal height of the steamer. When the steamer tilts and moves onto the loading platform with the forks, the proximity detection element is triggered.

[0026] In a first aspect, embodiments of this application provide a flipping mechanism, including a support, a drive motor, a limiting member, and a flipping member. The drive motor is connected to the support; the limiting member is fixedly mounted on the support and has a mating hole along its axial direction; the flipping member is rotatably disposed within the mating hole, is connected to the drive motor, and has a mating groove on its side wall for connecting with an item to be flipped; the drive motor drives the flipping member to rotate, thereby causing the item to be flipped to rotate, completing the flipping of the item. It is understood that the limiting member has a radial limiting effect on the object to be flipped, preventing it from detaching from the mating groove and rotating together with the flipping member to complete the flipping of the item.

[0041] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of this application.

[0042] In the description of the embodiments of this application, 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 indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0043] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," 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; 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, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0044] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0045] In the field of liquor production technology, grains such as corn and sorghum need to be steamed before fermentation.

[0046] In related technologies, the grain needs to be transferred to a steamer basket, and then the basket is moved to the steaming area by a forklift or overhead crane for steaming. After steaming, the basket is moved to the cooling area and the grain is removed and cooled manually. However, this method is inefficient.

[0047] To improve the efficiency of grain transfer and transportation, this application provides a flipping mechanism and a steamer lifting and flipping device. The solution provided by this application will be described in detail below with reference to the accompanying drawings.

[0048] Figure 1 This is a schematic diagram of the structure of a flipping mechanism 100 provided in one embodiment of this application; Figure 2 yes Figure 1 A cross-sectional view of the flipping mechanism 100 in the middle; Figure 3 yes Figure 1 Side view of the flipping mechanism 100 in the middle.

[0049] Reference Figure 1As shown, in a first aspect, this application provides a flipping mechanism 100, including a support 110, a drive motor 120, a limiting member 130, and a flipping member 140. The support 110 provides a mounting base for each component, and the drive motor 120 is connected to the support 110. The limiting member 130 is fixedly mounted on the support 110 and has a mating hole 131 along its axial direction. The flipping member 140 is rotatably disposed within the mating hole 131 and is connected to the drive motor 120. The side wall of the flipping member 140 has a mating groove 141 for connecting with an item to be flipped. The drive motor 120 drives the flipping member 140 to rotate, thereby causing the item to be flipped to rotate, completing the flipping of the item. The limiting member 130 has a radial limiting effect on the object to be flipped, preventing it from detaching from the mating groove 141 and rotating together with the flipping member 140 to complete the flipping of the item.

[0050] For example, a wear-resistant pad is provided between the flipping member 140 and the limiting member 130, that is, a wear-resistant pad is provided inside the mating hole 131 to avoid direct friction between the flipping member 140 and the limiting member 130, thereby improving the service life of both. Alternatively, for example, the wear-resistant pad can also be a wear-resistant bearing bush.

[0051] In some examples, the drive motor 120 is fixedly mounted on the support 110, and its output is fixedly connected to the flipping member 140. In other examples, the drive motor 120 is directly fixedly mounted on the limiting member 130, and its output is fixedly connected to the flipping member 140.

[0052] The limiting member 130 is cylindrical on the outside and has a mating hole 131 extending along its axial direction. The flipping member 140 is disposed in the mating hole 131 of the limiting member 130 via a rotating bearing. When the flipping member 140 is subjected to an external force, it can rotate in the mating hole 131.

[0053] like Figure 1 and Figure 2 As shown, the flipping member 140 is also cylindrical, and its diameter matches the diameter of the mating hole 131 of the limiting member 130. The flipping member 140 is provided with a mating groove 141. The mating groove 141 can be provided along the axial direction of the flipping member 140, or it can be provided on the side wall of the flipping member 140.

[0054] When the connecting part of the item to be flipped is connected to the mating groove 141, the connecting part is inserted into the mating groove 141. It should be noted that the cross-section of the connecting part of the item to be flipped is rectangular, and the cross-section of the mating groove 141 is also rectangular, with corresponding dimensions, allowing the connecting part of the item to be flipped to mate with the mating groove 141. It is understood that because both cross-sections are rectangular and they are mated together, the item to be flipped can be locked in the mating groove 141, allowing both to rotate simultaneously without relative rotation, thus improving the flipping stability of the item. Of course, it is understood that the cross-section of the connecting part of the item to be flipped can also be other polygons, such as a regular hexagon. The cross-section of the mating groove corresponds to the cross-section of the connecting part, and relative rotation does not occur after they are mated together.

[0055] Continue to refer to Figure 1 As shown, in some examples, the side wall of the limiting member 130 has an opening, and the mating groove 141 is provided on the side wall of the flipping member 140. The connecting part of the item to be flipped enters the mating hole 131 through the opening in the side wall of the limiting member 130 and connects with the mating groove 141. It should be noted that the size of the opening in the side wall of the limiting member 130 is greater than or equal to the size of the mating groove 141 on the flipping member 140, thereby ensuring that the connecting part of the item to be flipped can enter the mating hole 131 through the opening and connect with the mating groove 141. Moreover, the height of the connecting part of the item to be flipped is equal to or less than the depth of the mating groove 4141, that is, the connecting part of the item to be flipped does not protrude from the surface of the flipping member 140, ensuring that it will not interfere with the limiting member 413 during relative rotation.

[0056] For example, the cross-section of the opening on the side wall of the limiting member 130 and the cross-section of the mating groove 141 are both straight or V-shaped. It should be noted that "straight" means that the two planes on both sides of the opening are parallel, and the dimensions of the inner and outer sides of the opening are the same along the radial direction of the limiting member 130; the distance between the two opposite side walls of the mating groove 141 is the same from the inside to the outside. Figure 1 As shown, the opening on the side wall of the limiting member 130 and the cross-section of the mating groove 141 are both straight. The V-shape refers to the fact that along the radial direction of the limiting member 130, the opening size gradually increases from the inside to the outside, and the cross-section of the opening is V-shaped, similar to a trumpet mouth, facilitating the entry of the item to be flipped into the mating hole 131 from the outside of the opening. Similarly, along the radial direction of the flipping member 140, the cross-section of the mating groove 141 gradually increases from the inside to the outside, forming an overall V-shape, facilitating the mating connection of the item to be flipped. In these examples, the cross-section of the steamer handle is also V-shaped and matches the size of the mating groove 4141.

[0057] Continue to refer to Figure 1As shown, the opening on the side wall of the limiting member 130 faces vertically upward. When the flipping member 140 is in the initial position, the opening of the mating groove 141 faces upward and corresponds to the opening on the side wall of the limiting member 130, so that the connecting part of the item to be flipped can be easily inserted into the mating hole 131 through the opening on the side wall of the limiting member 130 and connected to the mating groove 141.

[0058] It is understandable that the opening direction of the side wall of the limiting member 130 can be any direction. However, when the opening direction of the side wall of the limiting member 130 is vertically upward, it is convenient to let the connecting part of the item to be flipped enter the mating hole 131 through the opening of the side wall of the limiting member 130 and connect with the mating groove 141.

[0059] After the item to be flipped connects with the mating groove 141 through the opening, the drive motor 120 drives the flipping component 140 to rotate. The item to be flipped follows the rotation of the flipping component 140. When the flipping component 140 rotates 180 degrees, the item to be flipped rotates 180 degrees simultaneously, thus completing the flipping process. It is understood that due to the restraining effect of the side wall of the limiting component 130, the item to be flipped will not detach from the mating groove 141. When it is necessary to remove the item to be flipped from the mating groove 141, the drive motor 120 rotates 180 degrees, aligning the mating groove 141 with the opening on the side wall of the limiting component 130, and then the item to be flipped is removed from the opening of the limiting component 130.

[0060] Continue to refer to Figure 2 As shown, the flipping component 140 includes a positioning stop 412, which is located inside the mating groove 140 in the axial direction. The positioning stop 412 has an inclined structure facing the opening direction of the mating groove 141, and is used to axially position the connecting part of the item to be flipped. For example, when the item to be flipped is a steamer basket, the connecting part of the item to be flipped specifically refers to the steamer basket handles located on both sides of the steamer basket.

[0061] like Figures 1 to 3 As shown, the flipping mechanism 100 also includes a reducer 160. The output end of the drive motor 120 is connected to the input end of the reducer 160, and the output end of the reducer 160 is connected to the flipping component 140. The reducer 160 is used to adjust the rotation speed of the flipping component 140, so as to facilitate the adjustment of the rotation speed and rotation angle of the item to be flipped.

[0062] For example, the drive motor 120 is a stepper motor or a servo motor with a self-locking function. When the drive motor 120 is unexpectedly de-energized, the item to be flipped can remain in its original position, preventing the item from rotating out of control due to the power failure.

[0063] Reference Figure 1As shown, the flipping mechanism 100 also includes a positioning detection component 150, which is disposed on the limiting member 130. The detection signal emitted by the positioning detection component 150 passes through the opening on the side wall of the limiting member 130. The positioning detection component 150 can determine whether the connecting part of the item to be flipped has passed through the opening and has completed the engagement with the mating groove 141 based on whether the detection signal is blocked. For example, the positioning detection component 150 can be configured as a photoelectric detection sensor. When the connecting part of the item to be flipped is placed on the flipping member 140, if the detection signal of the positioning detection component 150 is blocked, it indicates that the connecting part of the item to be flipped is entering the mating groove 141 through the opening. If the subsequent detection signal is continuously blocked, it indicates that the connecting part of the item to be flipped has not been placed in the mating groove 141. If the subsequent detection signal is restored, it indicates that the upper surface of the connecting part of the item to be flipped is completely located in the mating groove 141 and has been engaged with the mating groove 141.

[0064] To improve the flow and turning efficiency of the steamer basket 300 during grain steaming, this application provides a steamer basket lifting and turning device. (Refer to...) Figure 4 As shown, the steamer basket lifting and tilting device includes a lifting mechanism 200, a traveling mechanism, and a tilting mechanism 100 as described in the first aspect. The lifting mechanism 200 includes forks 210 for fixing the steamer basket 300. The lifting mechanism 200 is used to lift and lower the steamer basket 300 to facilitate taking the steamer basket 300 from the stack of steamer baskets 300. The traveling mechanism is located at the bottom of the lifting mechanism 200 and is used to drive the lifting mechanism 200 to move and thus transfer the steamer basket 300. The tilting mechanism 100 is located at the end of the forks 210. The handle of the steamer basket 300 is connected to a mating groove 141 in the tilting mechanism 100, and the tilting mechanism 100 is used to tilt the steamer basket 300.

[0065] For example, the lifting mechanism 200 can be configured as a stacker crane; the traveling mechanism can be configured as a rail-guided traveling mechanism or a railless autonomous navigation traveling mechanism. The forks 210 can be bidirectional telescopic forks, specifically single-stage telescopic forks, two-stage telescopic forks, or multi-stage telescopic forks, which can be selected and set according to actual needs. It should be noted that stacker cranes, rail-guided traveling mechanisms, railless autonomous navigation traveling mechanisms, single-stage telescopic forks, two-stage telescopic forks, and multi-stage telescopic forks are all existing technologies. Since no improvements have been made to these structures, their specific structures will not be described in detail here.

[0066] In some examples, the flipping mechanism 100 is a single unit located at the end of either of the two forks of the fork 210. One end of the steamer 300 is connected to the flipping mechanism 100, and the other end is movably connected to the other fork of the fork 210 via a hinged limiter. The flipping mechanism 100 drives the steamer 300 to flip 180 degrees.

[0067] Reference Figure 4 As shown, in this example, the lifting mechanism 200 is configured as a double-column stacker crane, and there are two flipping mechanisms 100. The two flipping mechanisms 100 are respectively set on the two forks of the fork 210 and are arranged opposite to each other. The two ends of the steamer 300 are respectively connected to the corresponding flipping mechanisms. The two flipping mechanisms 100 operate simultaneously to flip the steamer 300 180 degrees.

[0068] Figure 6 yes Figure 4 A schematic diagram showing the assembled components of the steamer tray lifting and tilting device. For example, as shown... Figure 6 As shown, the steamer tray lifting and tilting device also includes a fork extension detection component 180 and / or a steamer tray status monitoring component 170; the fork extension detection component 180 is used to detect whether the tilting mechanism 100 corresponds to the handle of the steamer tray 300 when the forks are extended. Specifically, the fork extension detection component 180 includes at least two photoelectric detection sensors arranged on the forks 210, and the at least two photoelectric detection sensors are respectively arranged on both sides of the tilting mechanism 100. When the handle of the steamer tray 300 is not fully aligned with the tilting mechanism 100, the handle of the steamer tray 300 triggers the photoelectric detection sensor located on the front or rear side of the tilting mechanism 100.

[0069] The steamer tray status monitoring component 170 is used to monitor whether the steamer tray 300 is in a horizontal state. For example, the steamer tray status monitoring component 170 includes at least two photoelectric detection sensors disposed on the forks 210. The at least two photoelectric detection sensors are disposed on the front and rear sides below the steamer tray 300. When the steamer tray 300 tilts forward or backward, the photoelectric detection sensors located on the front or rear sides of the steamer tray 300 are triggered.

[0070] For example, the steamer tray status monitoring component 170 includes a steamer tray forward tilt detection sensor 171 and a steamer tray backward tilt detection sensor 172, both of which are photoelectric detection sensors. The steamer tray forward tilt detection sensor 171 and the steamer tray backward tilt detection sensor 172 are both mounted on the forks of the fork 210, and are located on the front and rear sides of the tilting mechanism 100 respectively, emitting detection signals horizontally. When the fork 210 picks up the steamer tray and the steamer tray 300 is in a horizontal state, both the steamer tray forward tilt detection sensor 171 and the steamer tray backward tilt detection sensor 172 are located below the steamer tray, and the steamer tray 300 does not obstruct the steamer tray forward tilt detection sensor 171 and the steamer tray backward tilt detection sensor 172; that is, the steamer tray 300 will not trigger the activation of the steamer tray forward tilt detection sensor 171 and the steamer tray backward tilt detection sensor 172.

[0071] When the steamer tray 300 is in a horizontal position, the signals emitted by the forward tilt detection sensor 171 and the backward tilt detection sensor 172 are not blocked by the steamer tray 300, and neither is triggered. Once the steamer tray 300 tilts, either the forward tilt detection sensor 171 or the backward tilt detection sensor 172 will be triggered. Specifically, when the steamer tray 300 tilts forward, it will block the forward tilt detection sensor 171, thus triggering it; conversely, when the steamer tray 300 tilts backward, it will block the backward tilt detection sensor 172, thus triggering it.

[0072] Because the forward tilt detection sensor 171 and the backward tilt detection sensor 172 of the steamer tray are respectively set, they can simultaneously detect whether the steamer tray 300 is tilted, thus improving the accuracy of the tilt detection of the steamer tray 300. Of course, in order to reduce costs, the forward tilt detection sensor 171 or the backward tilt detection sensor 172 of the steamer tray can be set only on the fork arm of the fork 210.

[0073] For example, such as Figure 6 As shown, the fork extension detection component 180 includes at least two photoelectric detection sensors. The at least two photoelectric detection sensors are disposed on the fork arms of the fork 210 and respectively disposed on both sides of the flipping mechanism 100. Both emit detection signals upward. When the handle of the steamer 300 is not fully aligned with the flipping mechanism 100, the handle of the steamer 300 will trigger the photoelectric detection sensor located on one side of the flipping mechanism 100.

[0074] Specifically, when the forks 210 extend to pick up the steamer basket 300, if the photoelectric sensor 180 near the end of the forks 210 detects an object, it means that the forks 210 have extended to the vicinity of the steamer basket 300, and the extension speed of the forks 210 can be slowed down. If the photoelectric sensor 180 away from the end of the forks 210 detects an object, it means that the forks 210 have extended too much, and the tilting mechanism 100 has passed the handle of the steamer basket 300, requiring the forks 210 to be retracted and the position of the tilting mechanism 100 to be readjusted. During the process of picking up the steamer basket 300, when the photoelectric sensor on the side of the tilting mechanism 100 near the end of the forks 210 is triggered, the forks continue to extend. If neither the photoelectric sensor on the side of the tilting mechanism 100 near the end of the forks 210 nor the photoelectric sensor on the side of the tilting mechanism 100 away from the end of the forks 210 is triggered, it means that the handle of the steamer basket 300 is now aligned with the tilting mechanism 100.

[0075] In other examples, the steamer tray lifting and tilting device also includes a proximity detection element 173, which is located on the side of the fork platform 210 facing the steamer tray 300, i.e., at the front end of the platform. For example... Figure 4As shown, the proximity detection element 173 is positioned at the middle of the side of the loading platform facing the steamer tray 300, and its position is lower than the height of the steamer tray 300 when it is in a horizontal state. That is, when the steamer tray 300 is horizontal, the proximity detection element 173 is below the height of the lower surface of the steamer tray 300. During the process of the forks 210 picking up the steamer tray 300 and moving it to the loading platform, the proximity detection element 173 will not be triggered by the steamer tray 300. When the steamer tray 300 tilts and moves with the forks 210, the proximity detection element 173 will be triggered, thereby preventing the steamer tray 300 from colliding with the loading platform.

[0076] Under normal circumstances, the steamer status monitoring component 170 may trigger false alarms. For example, after the grain steaming process is completed, a large amount of steam will overflow when the top steamer 300 is lifted. At this time, the steamer status monitoring component 170 may be affected by the steam and trigger false alarms. Therefore, in this scenario, the steamer status monitoring component 170 can be turned off. Instead of monitoring, the proximity detection element 173 can be used to detect whether the steamer 300 is tilted, ensuring that the steamer 300 will not collide with the loading platform.

[0077] Furthermore, it is understood that the positioning detection component 150, the extension fork detection component 180, the steamer tray forward tilt detection sensor 171, the steamer tray backward tilt detection sensor 172, and the proximity detection element 173 are all connected to the controller. Those skilled in the art know how to connect them, how to acquire detection signals, and how to control them; this is prior art. Since this application does not involve improvements to the electrical control scheme, further details will not be provided.
