Description

Technical Field

[0001] This utility model relates to the technical field of yeast block handling equipment, specifically a stacking mechanism for a yeast block stacking and conveying system. Background Technology

[0002] In baijiu brewing, yeast blocks primarily function as saccharification, fermentation, and aroma-generating agents. Pressed yeast blocks, typically rectangular in shape, need to be quickly transported to the fermentation room and scientifically stacked to control the fermentation environment and optimize microbial metabolism. The pressed yeast blocks are fragile and rich in microbial flora (such as molds and yeasts). They must be handled gently during transport to avoid breakage or damage to their porous structure. Improper handling can hinder oxygen penetration and microbial reproduction, leading to decreased saccharifying enzyme activity or uneven fermentation of the mash. Therefore, the handling of yeast blocks is a crucial step in ensuring successful fermentation; improper handling can result in reduced yeast block utilization, fermentation crusting, or even the spoilage of the entire batch of mash.

[0003] Currently, the handling of yeast blocks is mainly done manually. Because yeast blocks are typically large and heavy, the process is extremely physically demanding. Manual handling requires not only careful attention to prevent the yeast blocks from slipping and falling, causing injuries, but also extreme caution to avoid collisions or scratches to the edges and vulnerable parts, which could lead to damage. Furthermore, manual stacking has low precision and poor stability, making it prone to rolling or collapsing. Therefore, only experienced and skilled workers can barely control losses and risks; novices are more likely to cause accidents or waste.

[0004] To address the aforementioned problems, the inventors designed a yeast block stacking and conveying system and designed a stacking mechanism for the system to replace manual stacking of yeast blocks. Utility Model Content

[0005] To address the technical problems existing in the background art, this utility model provides a stacking mechanism for a yeast block stacking and conveying system.

[0006] The technical solution of this utility model is as follows:

[0007] A stacking mechanism for a yeast block stacking and conveying system includes a support frame and a stacking module mounted on the support frame. The stacking module includes a conveying unit and a flipping unit.

[0008] The conveying unit can transport materials from front to back;

[0009] The flipping unit is located in front of and above the conveying unit. It includes a rotating shaft extending to the left and right. A four-bladed flipping wheel is provided on the rotating shaft corresponding to the position of the conveying unit. The four-bladed flipping wheel includes four blades that are evenly distributed in a windmill shape along the circumference of the rotating shaft. Adjacent blades are perpendicular to each other and form an L-shaped flipping station.

[0010] The four-blade tilting wheel is configured such that when the two centrally symmetrical blades rotate to the horizontal position, the lower blade extends backward and is lower than the top surface of the conveying unit by a preset distance, while the upper blade is higher than the top surface of the conveying unit.

[0011] The position of the rotating shaft is set so that when the yeast block flips from front to back, it contacts the top surface of the conveying unit.

[0012] The stacking mechanism of this application can replace manual labor in turning the yeast blocks from flat to upright, and can stack the yeast blocks tightly and horizontally, which is convenient for subsequent stacking operations. It not only realizes unmanned operation and avoids the safety and damage problems of manual handling, but also makes the stacking more regular and scientific, which is conducive to the subsequent fermentation and other biochemical reactions of the yeast blocks.

[0013] In the above scheme, the blade is an independent strip, and the four-bladed reversing wheel is formed by connecting the four blades tangentially to the cylindrical surface of the rotating shaft, which facilitates the installation and maintenance of the four-bladed reversing wheel.

[0014] Furthermore, one end of the blade is connected to the rotating shaft, and the other end extends tangentially along the connection point, extending beyond its adjacent blade by a predetermined length. This predetermined length is less than the thickness of the yeast block to prevent collision between the four-blade tilting wheel and the yeast block on the conveying unit during rotation, thus avoiding damage to the yeast block. Additionally, this predetermined length is preferably greater than 2 / 3 of the yeast block thickness to ensure sufficient contact area with the yeast block and guarantee stable support.

[0015] Furthermore, the flipping unit is equipped with two four-leaf flipping wheels, which are symmetrically distributed on both sides of the conveying unit along the rotation axis. The two four-leaf flipping wheels can flip the same yeast block together to ensure the smoothness of flipping the yeast block.

[0016] Furthermore, when the blades rotate to extend backward, they are staggered with the top surface of the conveying unit by a preset distance in the front-back direction, so that one end of the conveying unit is inserted between the two four-bladed turning wheels at a certain distance, increasing the contact area between the yeast block and the top surface of the conveying unit when it is turned, making the yeast block more stable and smooth when it is transferred from the four-bladed turning wheels to the conveying unit.

[0017] In the above scheme, the conveying unit includes a drive shaft, a driven shaft, and a conveyor belt connected to the two shafts. The support is also equipped with a rail, which supports the upper horizontal belt body of the conveyor belt to prevent the yeast blocks from tipping over when the conveyor belt moves due to the flexibility of the conveyor belt.

[0018] Furthermore, the conveyor belt includes two sub-belts arranged symmetrically on the left and right sides to distribute the load, improve the anti-torsion ability when conveying materials, and enhance the conveying stability.

[0019] To improve the stacking efficiency of the yeast blocks, multiple stacking modules are provided, which are evenly spaced along the left and right directions.

[0020] Furthermore, multiple flipping units share the same rotating shaft, and multiple conveying units share the same driving shaft and driven shaft.

[0021] This application also provides a yeast block palletizing and conveying system, including the above-mentioned stacking mechanism.

[0022] This utility model provides a stacking mechanism for a yeast block stacking and conveying system, which can replace manual labor in turning yeast blocks from flat to upright, and can tightly stack the yeast blocks horizontally, facilitating subsequent stacking operations. It not only achieves unmanned operation, avoiding the safety and damage problems of manual handling, but also results in a more orderly and scientific stacking, which is beneficial to the subsequent fermentation and other biochemical reactions of the yeast blocks.

[0029] like Figure 1 and Figure 2 As shown, this utility model embodiment provides a stacking mechanism for a yeast block stacking and conveying system, and also provides a yeast block stacking and conveying system including the stacking mechanism 1. The system includes not only the stacking mechanism 1, but also a pushing mechanism 2 and a conveyor belt 3.

[0030] like Figure 1As shown, the stacking mechanism 1 and the pushing mechanism 2 are located on opposite sides of the conveyor belt 3, and their positions correspond to each other. The conveyor belt 3 is used to transport the yeast blocks. The pushing mechanism 2 includes a frame, a cylinder mounted on the frame, and an L-shaped pusher plate connected to the telescopic end of the cylinder. The L-shaped pusher plate is used to intercept the yeast blocks, confining them within their inner corners. The cylinder is used to push the L-shaped pusher plate out along the conveyor belt 3 in a direction perpendicular to the conveyor belt 3, pushing the yeast blocks away from the conveyor belt 3 and towards the stacking mechanism 1. The stacking mechanism 1 flips the yeast blocks pushed by the pushing mechanism 2 for stacking. As the pushing mechanism 2 continues to push, after a certain amount of yeast blocks are stacked on the stacking mechanism 1, they are transferred in batches by other mechanisms to the fermentation room for stacking and storage. The batch transfer by other mechanisms mentioned here is a subsequent process and is unrelated to the stacking mechanism 1 and the conveying system described in this application, and will not be described here.

[0031] like Figure 2 As shown, the arranging mechanism 1 in this embodiment includes a support 11 and an arranging module disposed on the support 11. The arranging module includes a conveying unit 12 and a flipping unit 13.

[0032] The conveying unit 12 can convey materials from front to back;

[0033] The flipping unit 13 is located in front of and above the conveying unit 12. It includes a rotating shaft 131 extending to the left and right. A four-bladed flipping wheel 132 is provided on the rotating shaft 131 corresponding to the position of the conveying unit 12. The four-bladed flipping wheel 132 includes four blades that are evenly distributed in a windmill shape along the circumference of the rotating shaft 131. Adjacent blades are perpendicular to each other and form an L-shaped flipping station.

[0034] The four-blade tilting wheel 132 is configured such that when the two centrally symmetrical blades rotate to the horizontal, the lower blade extends backward and is lower than the top surface of the conveying unit 12 by a preset distance, while the upper blade is higher than the top surface of the conveying unit 12.

[0035] The position of the rotating shaft 131 is set so that when the yeast block is flipped from front to back, it contacts the top surface of the conveying unit 12.

[0036] In detail, the stacking module is located on top of the support 11. Its flipping unit 13 is used to flip the yeast blocks 90 degrees, stand them up, and transfer them to the conveying unit 12. The conveying unit 12 is used to move and temporarily store the yeast blocks. As the flipping unit 13 continuously transfers the yeast blocks, they are gradually stacked into a certain quantity on the conveying unit 12. It should be noted that the yeast blocks are typically rectangular blocks. When conveyed on the conveyor belt 3, they are transported flat, meaning the long side of the yeast block is parallel to the conveying direction of the conveyor belt 3, and the wide side is parallel to the width direction of the conveyor belt 3. When stacking, the yeast blocks need to be stood upright to improve their compressive strength and space utilization.

[0037] More specifically, the conveying unit 12 employs a belt conveyor. For easier understanding of the present application's solution, the rotation direction of the conveying unit 12 moving the yeast blocks from front to back is taken as clockwise.

[0038] In the flipping unit 13, the rotating shaft 131 extends to the left and right and is rotatably connected to the bracket 11. The bracket 11 is provided with a rotating driver that drives the rotating shaft 131 to rotate. The rotating shaft 131 rotates in a clockwise direction.

[0039] The four-bladed reversing wheel 132 mounted on the rotating shaft 131 is used to support the yeast blocks and rotate them 90 degrees. In this embodiment, to facilitate the installation and maintenance of the four-bladed reversing wheel 132, all four blades are independent slats. The four-bladed reversing wheel 132 is formed by connecting the four blades tangentially to the cylindrical surface of the rotating shaft 131.

[0040] Specifically, such as Figure 3 As shown, one end of the blade is detachably connected to the rotating shaft 131 by screws, and the other end extends tangentially along the cylindrical surface of the rotating shaft 131 at the connection point, with the blade surface tangential to the cylindrical surface of the rotating shaft 131. Four blades are evenly distributed circumferentially along the rotating shaft 131, with adjacent blades perpendicular to each other, forming a windmill shape. The extended portion of the blade mates with its adjacent blade to form an outward-facing L-shaped flipping station.

[0041] The four blades extend in a counterclockwise direction. That is, when the two centrally symmetrical blades are turned to the horizontal, the blade located below extends backward and the blade located above extends forward. Of the other two, the blade located behind extends upward and the blade located in front extends downward.

[0042] The rotating shaft 131 rotates intermittently, 90 degrees each time. Each rotation causes two centrally symmetrical blades to rotate horizontally, with the top surface of the upper blade flush with the top surface of the conveyor belt 3. After being pushed away from the conveyor belt 3 from front to back, the yeast block is pushed onto the upper horizontal blade. The rear side of the yeast block is blocked by the upward-extending blade on the right side, placing the yeast block in an L-shaped flipping position. The rotating shaft 131 drives the blades to rotate 90 degrees clockwise, flipping the yeast block 90 degrees backward and standing it upright. At this time, the bottom surface of part of the yeast block contacts the top surface of the conveying unit 12, and the conveying unit 12 rotates clockwise, moving the yeast block backward by a distance equal to the thickness of the yeast block. In addition, at this time, the blade that originally extended upward on the right side becomes a horizontal blade that extends backward, and its top surface is lower than the top surface of the conveying unit 12 by a preset distance. This preset distance can be selected as 3-7mm, so that the blade is slightly lower than the top surface of the conveying unit 12. In this way, the yeast block is transferred to the conveying unit 12, and the yeast block is changed from being supported by the blade to being supported by the conveying unit 12, so that the yeast block can be separated from the blade and move with the conveying unit 12.

[0043] The rotation of the conveying unit 12 during the stacking operation is also intermittent. Each rotation moves the yeast blocks backward by a distance equal to the thickness of one yeast block, achieving tight stacking of the yeast blocks. When the number of yeast blocks stacked on the conveying unit 12 reaches a preset number, the conveying unit 12 moves the preset number of yeast blocks a preset distance further away to facilitate batch grabbing of the yeast blocks by subsequent mechanisms.

[0044] To prevent the four-bladed turning wheel 132 from colliding with the yeast blocks on the conveying unit 12 and damaging them during rotation, the extended end of the blade extends beyond its adjacent blade by a predetermined length, which is less than the thickness of the yeast block. However, to provide sufficient support area for the yeast blocks and ensure stable support, the predetermined length of the extended end of the blade extending beyond its adjacent blade is greater than 2 / 3 of the thickness of the yeast block.

[0045] As can be seen from the above description, since the end of the belt conveyor is arc-shaped, the four blades of the four-blade turning wheel 132 in this embodiment are arranged in a windmill shape and extend counterclockwise. This allows the rotating shaft to be closer to the top surface of the conveying unit 12, increasing the contact area between the yeast block and the conveying unit 12. This not only improves the stability of the four-blade turning wheel 132 when transferring the yeast block to the conveying unit 12, but also improves the stability of the conveying unit 12 when moving the yeast block.

[0046] At the same time, it can also meet the requirements of having a relatively long plate to correspond to the width of the yeast block and a relatively short plate to correspond to the thickness of the yeast block, so as to achieve the requirement of stable support. Furthermore, it can also prevent the four-leaf flipping wheel 132 from colliding with the yeast block on the conveying unit 12 when it rotates.

[0047] Furthermore, the flipping unit 13 is provided with two four-leaf flipping wheels 132, which are symmetrically distributed on both sides of the conveying unit 12 along the axis of rotation 131. Not only can the two four-leaf flipping wheels 132 flip the same yeast block together to ensure the smoothness of flipping the yeast block, but the axis of rotation 131 can also be set closer to the top surface of the conveying unit 12. When the blades are rotated to extend backward, they are staggered with the top surface of the conveying unit 12 by a preset distance in the front-back direction. This allows one end of the conveying unit 12 to be inserted between the two four-leaf flipping wheels 132 at a certain distance, increasing the contact area between the yeast block and the top surface of the conveying unit 12 when it is flipped. This makes the yeast block more stable and smooth when it is transferred from the four-leaf flipping wheels 132 to the conveying unit 12.

[0048] With the above settings, when the yeast blocks are flipped up, they can be almost entirely supported by the top surface of the conveying unit 12.

[0049] Please refer to again Figure 2As shown, the conveying unit 12 in this embodiment adopts a belt conveyor, which specifically includes a drive shaft 121, a driven shaft 122, and a conveyor belt 123 connected to the two shafts. The drive shaft 121 and the driven shaft 122 are arranged horizontally and parallel to each other, and pulleys are provided on both for the conveyor belt 123 to connect. The support 11 is provided with a conveyor driver to drive the drive shaft 121 to rotate.

[0050] In this embodiment, the driven shaft 122 is located in front of the driving shaft 121, and the rotating shaft 131 is set in relation to the driven shaft 122, thereby offsetting the setting positions of the rotary driver and the conveying driver, providing sufficient space for their setting.

[0051] Preferably, the conveyor belt 123 is a synchronous belt and the pulley is a synchronous pulley to avoid slippage of the conveyor belt 123 during the movement of the yeast.

[0052] In addition, the support frame 11 is also equipped with a support rail 124, which is located below the horizontal belt body on the upper side of the conveyor belt 123 to prevent the yeast blocks from tipping over when the conveyor belt 123 moves with it due to its flexibility. The support rail 124 extends back and forth and is connected to the support frame 11 by a support rod.

[0053] Furthermore, the conveyor belt 123 includes two sub-belts 1231 arranged symmetrically on the left and right sides. The drive shaft 121 and the driven shaft 122 are respectively provided with two pulleys for connecting the two sub-belts 1231. By having the two sub-belts 1231 jointly support and move the unified block of yeast, the load of the conveying unit 12 can be distributed, the anti-torsion ability during material conveying can be improved, and the conveying stability can be enhanced.

[0054] In addition, the support 11 has multiple stacking modules, which are evenly spaced along the left and right direction. Multiple flipping units 13 share the same rotating shaft 131, and multiple conveying units 12 share the same driving shaft 121 and driven shaft 122.

[0055] In this embodiment, there are three stacking modules, and the corresponding pushing mechanism 2 is equipped with three sets of cylinders and L-shaped push plates. When the four-leaf flipping wheels 132 of the three stacking modules are carrying yeast blocks, the rotary driver is started, and the flipping unit 13 flips the three yeast blocks at the same time. As stacking continues, a yeast block array with a preset number of three columns is formed, which improves the stacking efficiency of the yeast blocks in subsequent processes.

[0056] This utility model provides a stacking mechanism for a yeast block stacking and conveying system, which can replace manual labor in turning yeast blocks from flat to upright, and can tightly stack the yeast blocks horizontally, facilitating subsequent stacking operations. It not only achieves unmanned operation, avoiding the safety and damage problems of manual handling, but also results in a more orderly and scientific stacking, which is beneficial to the subsequent fermentation and other biochemical reactions of the yeast blocks.
