Description

Technical Field

[0001] The invention belongs to the technical field of grain brewing, and in particular relates to an automatic material distribution system for a cellar group. Background Art

[0002] Currently, the production of condiments such as soy sauce, vinegar, and alcohol requires that grain be fermented in a cellar cluster after koji making. Typically, a cellar cluster consists of several cellar units distributed in an array, and a distribution cart is used to evenly distribute grain along each cellar unit. There are usually two ways to add material to the distribution cart during the distribution process. One is that multiple people work together to move the feed pipe following the distribution cart. The disadvantage of this method is that it is labor-intensive and can easily cause the feed pipe to have a dead bend and become blocked during transportation. The other method is that the feed pipe is fixed, and the distribution cart periodically returns to the discharge port of the feed pipe for adding material. The disadvantage of this method is that the distribution cart has too many invalid strokes, which not only makes the route planning of the distribution cart complicated and difficult to control, but also seriously affects the distribution efficiency of the cellar cluster.

DETAILED DESCRIPTION

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "multiple" and "several" is two or more, unless otherwise clearly and specifically defined.

[0019] Please also refer to Figures 1 to 11Now, the automatic material distribution system for a cellar group provided by the present invention is described. The automatic material distribution system for the cellar group includes a ceiling rail 30, a first gantry trolley 10, a second gantry trolley 20, a material distribution trolley 40, two steering mechanisms 50, and a material distribution pipe 60. The ceiling rail 30 is arranged above both sides of the cellar group 90. The first gantry trolley 10 and the second gantry trolley 20 respectively span the cellar group 90 and are connected to the ceiling rail 30. The travel speed of the first gantry trolley 10 is twice that of the second gantry trolley 20. The material distribution trolley 40 is connected to the first gantry trolley 10 in a transverse sliding manner and follows the longitudinal movement of the first gantry trolley 10. The two steering mechanisms 50 are respectively provided at the lateral ends of the second gantry trolley 20. The material distribution pipe 60 is arranged along the ceiling rail 30 on one side of the cellar group 90. The material distribution pipe 60 sequentially passes through the two steering mechanisms 50 and is fixedly connected to the first gantry trolley 10. The material distribution pipe 60 is connected to the material distribution trolley 40. A drag chain 70 is connected to the material distribution pipe 60, and the drag chain 70 is used to cooperate with the two steering mechanisms 50 to guide the material distribution pipe 60 to bend and turn.

[0020] It should be understood that, as is conventional technology, the overhead rail 30 in this embodiment can be understood as a track with a certain suspended height. Its installation base can be a load-bearing wall or column within the fermentation workshop, or a gantry load-bearing beam spanning above the cellar group 90 within the fermentation workshop, without limitation. There are two overhead rails 30, one on each side of the cellar group 90. The first gantry trolley 10 and the second gantry trolley 20 are connected to one of the overhead rails 30 at both ends. The first gantry trolley 10 and the second gantry trolley 20 each have a power system that drives themselves along the overhead rail 30. It can also be considered that the first gantry trolley 10 and the second gantry trolley 20 are both common overhead cranes in industrial workshops. In addition, the material distribution vehicle 40 used in this embodiment is the same as the existing material distribution vehicle 40. It only needs to connect the material distribution pipe 60 to the feeding port of the material distribution vehicle 40. The material distribution vehicle 40 can be self-propelled or passively moved by the drive of the first gantry vehicle 10. Since the cellar group 90 is usually composed of a number of cellar units distributed in a vertical and horizontal array, the movement trajectory of the material distribution vehicle 40 in this embodiment can be to first align the cellar units in one vertical column, and then the material distribution vehicle 40 will move horizontally to the next vertical column after the material distribution is completed in each cellar unit in the vertical column from front to back, and move in the opposite direction to distribute the material from back to front, and repeat this process until the distribution of the entire cellar group 90 is completed. The material distribution vehicle 40 can also first distribute the material horizontally and then move forward and backward, which is not limited here.

[0021] The working principle of the automatic material distribution system for the cellar group provided in this embodiment can be combined with Figure 1It is understood that the two steering mechanisms 50 are disposed at the lateral ends of the second gantry 20 and cooperate with the drag chain 70 on the fabric pipe 60. The cooperation between the steering mechanisms 50 and the drag chain 70 can be understood as a chain transmission method. The two steering mechanisms 50 guide the fabric pipe 60 in a U-shape, and the second gantry 20 as a whole acts as a movable pulley (the travel distance of the first gantry 10 is equal to the sum of the travel lengths of the fabric pipe 60 on both sides of the second gantry 20). Therefore, the travel speed of the first gantry 10 is configured to be twice that of the second gantry 20, so that the fabric pipe 60 is always in a taut state. Moreover, although the bending position of the fabric pipe 60 changes continuously, it can always be turned in a circular arc shape under the bending guidance of the steering mechanism 50, thereby avoiding the phenomenon of dead bends in the fabric pipe 60 when bending and changing direction.

[0022] Compared with the prior art, the automatic material distribution system for a cellar group provided in this embodiment utilizes a ceiling rail 30 arranged above both sides of a cellar group 90 to install a first gantry car 10 and a second gantry car 20. A distribution pipe 60 is arranged along the ceiling rail 30 and forms a dynamic path that bypasses the second gantry car 20 and is fixed to the first gantry car 10 based on the cooperation of a drag chain 70 and two steering mechanisms 50. When the first gantry car 10 drives the distribution car 40 to move synchronously, the first gantry car 10 simultaneously pulls the distribution pipe 60, and the second gantry car 20 follows the first gantry car 10 at half the speed of the first gantry car 10, so that the second gantry car 20 can form a fixed path. It plays a role similar to that of a movable pulley, thereby ensuring that the fabric pipe 60 always remains in a straight state on the overhead rail 30 and that material can be added to the fabric cart 40 at any time, without the need for manual dragging of the fabric pipe 60. This not only saves manpower and reduces labor intensity, but also avoids ineffective travel of the fabric cart 40 and improves fabric efficiency. On this basis, since the fabric pipe 60 can utilize the cooperation of the drag chain 70 connected thereto and the steering mechanism 50 to obtain stable bending and steering, it is possible to avoid dead bends at the bending parts of the fabric pipe 60 that may cause material blockage, thereby improving the smoothness of the fabric operation and further promoting the improvement of fabric efficiency.

[0023] In some embodiments, see Figure 1 、 Figure 6 and Figure 8 The above-mentioned automatic material distribution system for the cellar group also includes two sets of chain guide mechanisms 80 respectively hoisted and fixed above the ceiling rails 30 on both sides of the cellar group 90; the chain guide mechanism 80 includes a hanger 81 and a plurality of chain guide frames 82 longitudinally spaced apart on the hanger 81; wherein, one end of the chain guide frame 82 is suspended and provided with a guide groove 821, and each link of the drag chain 70 is provided with a guide member suitable for sliding into the guide groove 821.

[0024] The installation base of the hanger 81 can be the same as that of the overhead rail 30, such as being fixed on the load-bearing wall or column structure of the fermentation workshop, or being fixed on the gantry beam above the cellar group 90, which is not limited here. The above-mentioned guide member can be a guide block with a width smaller than the groove width of the guide groove 821, or a guide wheel 71 set on the chain link (here the guide wheel 71 cooperates with both the guide groove 821 and the slot 530 of the steering mechanism 50). The hanger 81 is used as the installation base of the guide chain frame 82. One end of the guide chain frame 82 is suspended in the air to provide sufficient space. On this basis, the guide groove 821 is used to guide each link of the drag chain 70, so that the drag chain 70 can always move along the trajectory of the guide groove 821, thereby enabling the drag chain 70 to stably constrain the fabric pipe 60 and ensure the smooth flow of materials in the fabric pipe 60.

[0025] For some possible implementations, see Figures 8 to 10 Each chain guide frame 82 is rotatably connected to the hanger 81, and each chain guide frame 82 is provided with a downwardly extending swing arm 822 at the end away from its guide groove 821, and the portion of the chain guide frame 82 deviating from its rotation axis is overlapped and supported on the hanger 81; both ends of the second gantry vehicle 20 are provided with a longitudinally extending guide rod 21; wherein, when the guide rod 21 contacts the swing arm 822 as the second gantry vehicle 20 moves, the suspended end of the swing arm 822 flips upward to disengage the guide groove 821 from the drag chain 70.

[0026] The guide chain frame 82 is rotatably connected to the hanger 81 to obtain the freedom of upside down flipping. In the normal state, the guide chain frame 82 maintains the middle part of the hanger 81 on the basis of the gravity of its suspended end, and in this state it guides the drag chain 70; as the various chain links on the running drag chain 70 of the first gantry car 10 and the second gantry car 20 pass through the two steering mechanisms 50 in turn, when passing through the steering mechanism 50, it is necessary to make the drag chain 70 disengage from the guide groove 821, so by providing a swing arm 822 on the guide chain frame 82 and a guide rod 21 on the second gantry car 20, the abutment of the guide rod 21 on the swing arm 822 drives the suspended end of the guide chain frame 82 to flip upward, so that the guide groove 821 is higher than the drag chain 70, ensuring that the drag chain 70 can smoothly pass through the steering mechanism 50 to achieve bending and steering, avoiding the problem that the drag chain 70 cannot disengage from the guide groove 821 and cannot enter the steering mechanism 50 for smooth steering, which can improve the bending and switching stability of the fabric pipe 60.

[0027] Specifically, please combine Figures 8 to 10 It is understood that in this embodiment, a roller 8221 is provided at the lower end of the swing arm 822, and guiding slopes 211 are provided at both ends of the guide rod 21, and the side wall of the guide rod 21 located between the two guiding slopes 211 forms a limiting surface 212; wherein, the guiding slope 211 is used to guide the roller 8221 to roll into or out of the limiting surface 212 to drive the swing arm 822 to swing.

[0028] When the second gantry vehicle 20 moves, the guide rod 21 contacts the roller 8221 at the lower end of each swing arm 822 in turn, causing the roller 8221 to roll from the guide inclined surface 211 at one end of the guide rod 21 to the limit surface 212. In this process, the swing arm 822 can be driven to swing, thereby causing the guide groove 821 to break away from the drag chain 70. When the roller 8221 rolls to the other end of the guide rod 21, the corresponding chain link has been released from the constraint range of the guide groove 821 under the guidance of the steering mechanism 50. Therefore, the roller 8221 rolls away from the limit surface 212 along the other guide inclined surface 211, thereby causing the swing arm 822 to automatically reset under the action of the gravity of its own suspended end. The automatic flipping of the guide chain frame 82 is realized purely from the mechanical structure without the need for electronic control components, and the operation reliability is strong.

[0029] In some embodiments, see Figure 5 、 Figure 7 and Figure 8 A supporting platform 811 is provided on the hanger 81, and the first gantry vehicle 10 and the second gantry vehicle 20 both have a load-bearing surface 11 that is flush with the supporting platform 811; wherein, each link of the drag chain 70 is provided with a support plate 72 at the bottom, and a plurality of casters 721 for rolling the supporting platform 811 and the load-bearing surface 11 are distributed in an array on the support plate 72.

[0030] Utilizing the casters 721 to roll the supporting platform 811 and the load-carrying table 11 can provide stable support force for the drag chain 70, thereby providing support force for the fabric tube 60. This not only ensures the ease of movement of the fabric tube 60, thereby preventing the fabric tube 60 from being subjected to excessive traction, but also prevents the fabric tube 60 from extending too long and falling and bending under the action of gravity, thereby ensuring the coordination stability of the drag chain 70 and the guide groove 821, and further ensuring the posture stability of the fabric tube 60.

[0031] As a specific embodiment of the steering mechanism 50, please refer to Figure 11 The steering mechanism 50 includes a bogie 51, a rotary drive member 52, and a steering chain disc 53; the bogie 51 is fixedly connected to the second gantry vehicle 20, the rotary drive member 52 is fixedly connected to the bogie 51, the steering chain disc 53 is connected to the output end of the rotary drive member 52, and a plurality of slots 530 are evenly distributed along the edge of the steering chain disc 53; each link of the drag chain 70 is provided with a guide wheel 71 suitable for being embedded in the slot 530, and the guide wheel 71 is suitable for rolling into the guide groove 821.

[0032] The rotary drive member 52 can specifically be an electric motor, a hydraulic motor, or a pneumatic motor. The rotary drive member 52 directly or indirectly drives the steering chain disc 53 to rotate, thereby causing the guide wheel 71 embedded in the retaining groove 530 to shift the corresponding chain link, thereby constraining the distribution tube 60 to the position of the chain link to complete the bending and reversing process. This not only provides a simple and reliable overall structure, but also prevents the distribution tube 60 from slipping during the bending and reversing process through the cooperation between the guide wheel 71 and the retaining groove 530, thereby improving the bending and reversing stability of the distribution tube 60. Furthermore, the guide wheel 71 also serves as a guide member that cooperates with the guide groove 821 to constrain the running trajectory of the drag chain 70. This not only improves the compactness of the motion coordination structure between each chain link and the guide groove 821, but also reduces the relative motion resistance between the chain link and the guide groove 821, thereby improving the stability of the distribution operation process.

[0033] Alternatively, see Figure 11 In this embodiment, the rotating drive component 52 includes a slide 521, a swivel seat 522 and a driving motor 523; the slide 521 is longitudinally slidably connected to the bogie 51 and an elastic buffer member 54 is provided between the slide 521 and the bogie 51, the swivel seat 522 is rotatably connected to the slide 521 and coaxially connected to the steering chain disc 53, and the driving motor 523 is fixed to the slide 521 and is transmission-connected to the swivel seat 522 to drive the swivel seat 522 to rotate.

[0034] The driving motor 523 is connected to the slide 521 and can maintain stable driving of the swivel seat 522 when the slide 521 moves. The elastic buffer 54 can specifically be a rubber buffer pad or a spring. By setting the elastic buffer 54, the slide 521 can be formed in a flexible connection state on the bogie 51. In this way, during the bending and reversing process of the cloth tube 60 around the steering chain disc 53, the slide 521 can be driven to swing flexibly based on the magnitude of the traction force on the cloth tube 60. On the one hand, it is to avoid the cloth tube 60 from being damaged by excessive force, and on the other hand, it is to avoid the jamming phenomenon between the drag chain 70 and the steering chain disc 53, thereby ensuring the smoothness and stability of the cloth operation.

[0035] Specifically, such as Figure 11 As shown, a worm 5211 is rotatably connected to the slide 521, one end of which is connected to the drive motor 523. A worm wheel 5221 is mounted on the rotating seat 522, and the worm wheel 5221 is meshed with the worm 5211. The drive motor 523 drives the worm 5211 to rotate, thereby driving the worm wheel 5221 to rotate, and ultimately achieving the rotational motion of the steering chain 53 following the rotating seat 522. The transmission method is simple, compact, and highly reliable.

[0036] As a specific structural form of the steering chain disc 53, please refer to Figure 11The steering chain disc 53 includes a ring seat 531 and a face plate 532 coaxially fixed to the ring seat 531. The diameter of the face plate 532 is larger than that of the ring seat 531, and a groove 530 is provided on the edge of the face plate 532. Each link of the drag chain 70 is provided with a lateral support wheel 73, which is used to roll and support the circumferential wall of the ring seat 531. The face plate 532 is used to achieve meshing connection with each link. At the same time, considering that the distribution pipe 60 exerts a large lateral force on the steering chain disc 53 during bending and reversing, a ring seat 531 with a smaller diameter is provided below the face plate 532. On the one hand, the ring seat 531 is used to achieve a fixed connection with the rotating seat 522. On the other hand, the circumferential wall of the ring seat 531 serves as an annular support surface, providing rolling support for the lateral support wheels 73 on the chain links, thereby improving the bending and reversing stability of the distribution pipe 60.

[0037] For some possible implementations, see Figure 5 Each link of the drag chain 70 has a top plate 74, which is connected to the support plate 72 by a number of spaced-apart vertical rods 75; the fabric pipe 60 is passed between the top plate 74 and the support plate 72 and each side of the fabric pipe 60 has at least one vertical rod 75; the lateral support wheel 73 is rotatably connected to the vertical rod 75 located on the inner side of the curve of the fabric pipe 60; adjacent chain links are connected by pull rods 76 hinged to the top plate 74 and the support plate 72.

[0038] Four vertical rods 75 can be used to connect the top plate 74 and the supporting plate 72 as a whole to form a chain link. In this way, the two sides of the cloth tube 60 can have two vertical rods 75 for horizontal radial constraints. At the same time, the top plate 74 and the supporting plate 72 can provide vertical diameter constraints for the cloth tube 60, which can not only prevent the cloth tube 60 from slipping off the chain link, but also ensure the flexibility of the cloth tube 60 to bend between the top plate 74 and the supporting plate 72. On this basis, the vertical rods 75 are used as the installation base of the lateral support wheels 73, thereby improving the structural compactness and movement stability of the chain link. The chain links of the drag chain 70 are connected by pull rods 76. The two ends of the pull rod 76 are hinged to the adjacent links respectively, and at the same time, hinge points are set at both ends of each link. The distance between the two hinge points is consistent with the distance between the two hinge points of the pull rod 76, so that the bending flexibility between adjacent links can be guaranteed; further, a guide wheel 71 is installed on the hinge points at both ends of the link respectively, and the guide wheel 71 and the pull rod 76 can share the same rotating shaft for connection, and the distribution spacing of each slot 530 on the surface plate 532 matches the center distance of adjacent guide wheels 71, thereby ensuring the meshing stability between each link and the surface plate 532, thereby improving the bending and steering stability of the fabric tube 60.

[0039] Please note that Figure 2 and Figure 7The first gantry vehicle 10 is provided with a movable material pipe 61. One end of the movable material pipe 61 is connected to the feeding port of the material distribution vehicle 40, and the other end is connected to the material distribution pipe 60.
