Blocking mechanism and logistics transmission line

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure is based on the Chinese patent application with application number 202311293186.X, application date October 8, 2023, and invention name “Blocking mechanism and logistics transmission line”, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this disclosure as a reference. Technical Field

[0003] New energy batteries are being used more and more widely in life and industry. For example, new energy vehicles equipped with batteries have been widely used. In addition, batteries are also being increasingly used in energy storage fields.

[0004] The present disclosure relates to the field of logistics, and in particular to a blocking mechanism and a logistics transmission line. Background Art

[0005] In related technologies, to keep pace with production, a blocking mechanism is typically installed between the front and rear workstations on a logistics conveyor line transporting workpieces. When the rear workstation is operating, the blocking mechanism blocks the workpiece on the front workstation. When the rear workstation needs to dock with the front workstation and stops operating, the blocking mechanism allows the workpiece on the front workstation to be transferred to the rear workstation. Current blocking mechanisms are not suitable for operations where the logistics conveyor line at the rear workstation moves in both directions, allowing workpieces to be transferred between multiple layers of logistics conveyor lines.

[0006] Summary of the Invention

[0007] In view of this, the embodiments of the present disclosure hope to provide a blocking mechanism and a logistics transmission line that can effectively solve the production rhythm problem of transferring workpieces between multiple layers of logistics transmission lines.

[0008] To achieve the above-mentioned purpose, an embodiment of the present disclosure provides a blocking mechanism, comprising a blocking assembly and a trigger member. The blocking assembly comprises a transmission member, a blocking member and an elastic member. The blocking member comprises a first position in which it is blocked and a second position in which it is released from the blockage. The transmission member is connected to the blocking member, and the elastic member is capable of placing the blocking member in the first position. The trigger member is capable of contacting the transmission member in two opposite directions so that the blocking member is in the second position. The elastic member stores elastic potential energy under the action of the transmission member, and when the trigger member is disengaged from the transmission member, the elastic member is capable of restoring the blocking member from the second position to the first position.

[0009] The trigger member can push the transmission member, which in turn drives the blocking member to move, causing it to reach the second position to release the blocking function. When the trigger member is no longer in contact with the transmission member, the elastic member returns the blocking member to the first position to resume blocking. The trigger member can engage the transmission member in two opposing directions, enabling workpieces to be transferred between multiple layers of transmission lines.

[0010] In some embodiments, the blocking assembly further includes a base, the blocking member being rotatably connected to the base, and the transmission member including a push rod capable of linear movement relative to the base, one end of the push rod being connected to the blocking member, and the other end of the push rod being capable of contacting the trigger member.

[0011] The base serves to support the push rod and the blocking member. The push rod can move in a straight line relative to the base, and the blocking member is rotatably connected to the base, thereby converting the linear motion of the push rod into rotation of the blocking member, thereby realizing the state change of the blocking member between the first position and the second position.

[0012] In some embodiments, the base has a through hole, the push rod is passed through the through hole, and the push rod is restricted to perform linear motion in the direction of the axis of the through hole.

[0013] In some embodiments, the base includes a first base and a second base, one of the first base and the second base has a slide rail, the other of the first base and the second base has a slide groove, and the first base and the second base are slidably matched through the slide rail and the slide groove; the blocking member is rotatably connected to the first base, and the push rod is fixedly connected to the second base.

[0014] The slide rail and the slide groove are slidably matched, and the second base can move linearly relative to the first base, and together with the movement of the push rod fixed thereon, the push rod moves linearly. The use of the slide rail and slide groove structure can effectively reduce costs.

[0015] In some embodiments, the base includes a base body and a linear bearing. The blocking member is rotatably connected to the base body. The linear bearing is disposed on the base body, and the linear bearing has a through hole, and the push rod is inserted into the through hole.

[0016] The linear bearing is a linear motion system with the advantages of low friction and high stability. The push rod is inserted into the through hole and contacts and rubs with the linear bearing during movement. By reducing the friction loss of the push rod during movement, the service life of the blocking mechanism can be effectively improved.

[0017] In some embodiments, the seat body includes a seat plate and an ear seat. The linear bearing is disposed on the seat plate. The ear seat is connected to the seat plate and includes a base plate and two first ear plates spaced apart from each other on the base plate. The blocking member is located between the two first ear plates and is rotatably connected to the two first ear plates.

[0018] The seat body is divided into the seat plate and the ear seat, and the two parts can be integrally formed to simplify the installation of the blocking mechanism; the two parts can also be detachably connected to facilitate processing and maintenance.

[0019] In some embodiments, the transmission member further includes a roller, the push rod includes a rod body and a rod seat connected to one end of the rod body, the rod seat includes two second ear plates spaced apart, the roller is located between the two second ear plates and is rotatably connected to the two second ear plates, and the roller is used to roll in contact with the trigger member.

[0020] The roller converts the contact between the trigger member and the transmission member into rolling contact, which can effectively reduce friction loss and movement resistance during the contact process.

[0021] In some embodiments, the elastic member is a compression spring, which is sleeved on the rod body and located between the rod seat and the base. The outer dimension of the rod seat projected along the axial direction of the rod body is larger than the inner diameter of the compression spring to block the compression spring.

[0022] The compression spring is sleeved on the rod body and located between the rod seat and the base, which can simplify the installation of the compression spring. The two ends of the compression spring do not need to be connected to the rod seat and the base. The compression performance of the compression spring can alleviate the vibration and impact of the blocking member during operation, reduce noise, and reduce wear and damage between components, thereby extending the service life of the blocking mechanism.

[0023] In some embodiments, the elastic member is a compression spring, which is sleeved on the push rod and located on a side of the base away from the blocking member.

[0024] In some embodiments, the elastic member is a tension spring, which is sleeved on the push rod and located on a side of the base close to the blocking member.

[0025] In some embodiments, the elastic member is a torsion spring, which is provided at the connection between the blocking member and the base, and two torsion legs of the torsion spring respectively abut against the blocking member and the base.

[0026] In some embodiments, the elastic member is a rectangular spring.

[0027] The cross-sectional shape of the material used to make the rectangular spring is rectangular, and it has the advantages of being able to withstand high-speed amplitudes, and having good stability and fatigue resistance, and can better adapt to the application scenarios of the blocking mechanism.

[0028] In some embodiments, the blocking member includes a rotating portion and a pushing portion, the rotating portion being rotatably connected to the base, the pushing portion having an escape groove and an elongated hole, two escape grooves being formed on either side of the pushing portion, and the elongated hole connecting the escape grooves on both sides. One end of the push rod is connected to the pushing portion and is movable along the elongated hole.

[0029] The elongated hole is provided on the pushing portion to avoid the restriction of the degree of freedom when the linear movement of the push rod is converted into the rotation of the blocking member. The avoidance groove is provided on the pushing portion to reduce the diameter of the push rod, making the structure more compact.

[0030] In some embodiments, the blocking member includes a blocking surface and an avoidance surface, the blocking surface faces away from the base, and the avoidance surface is arranged at an angle with the blocking surface, and the angle is less than 90 degrees.

[0031] The avoidance surface is provided to reduce the linear travel of the push rod and the triggering height of the triggering member under the same conditions, so that the blocking member can release the blocking.

[0032] In some embodiments, the blocking member includes a blocking surface and a limiting surface, wherein the blocking surface faces away from the base and the limiting surface faces the base. When the blocking member is in the first position, the limiting surface abuts against the base.

[0033] When the blocking member is in the first position, the limiting surface can disperse the force applied by the blocked object to the abutment portion between the limiting surface and the base by limiting the rotational stroke of the blocking member.

[0034] In some embodiments, the trigger member includes a guide portion and a trigger portion, the two guide portions are respectively located at both ends of the trigger portion, the guide portion has a first guide end and a second guide end, the height of the first guide end is greater than that of the second guide end, the first guide end is connected to the trigger portion, and a smooth transition is formed between the contact surface of the guide portion for contacting the transmission member and the contact surface of the trigger portion for contacting the transmission member.

[0035] When the trigger member contacts the transmission member, the guide member first contacts the transmission member, pushing the transmission member to move. When the trigger member contacts the transmission member, the blocking member moves to near the second position. When the trigger member no longer contacts the transmission member, the elastic member returns the blocking member to the first position. The smooth transition between the contact surface of the guide member and the contact surface of the trigger member enhances transmission stability.

[0036] In some embodiments, the contact surface of the guide portion is a plane, and the contact surface of the contact portion is an arc surface.

[0037] The present disclosure also provides a logistics transmission line, comprising a first transmission line, a second transmission line, and any of the aforementioned blocking mechanisms. The first transmission line is used to transport a workpiece. The second transmission line is used to transport the workpiece. The blocking assembly is disposed on a fixed component of the first transmission line or a fixed portion of the second transmission line, and the trigger is disposed on a moving portion of the second transmission line. The blocking member is in the first position to prevent the workpiece from falling. The trigger is capable of contacting the transmission member to position the blocking member in the second position, enabling the workpiece to move between the first and second transmission lines.

[0038] The blocking mechanism is set on the first logistics transmission line and the second logistics transmission line. The trigger member can be set on the bidirectionally moving logistics transmission line, and the blocking member is triggered to change its position at an appropriate time, effectively solving the production rhythm problem of logistics transmission.

[0039] In some embodiments, the first transmission line comprises multiple layers of horizontal transmission lines, each of which is provided with the blocking assembly. The second transmission line is a vertical elevator. The blocking assembly is provided on the fixed frame of the vertical elevator at a location corresponding to each layer of the horizontal transmission line, or the blocking assembly is provided on each layer of the horizontal transmission line.

[0040] Due to the provision of the above-mentioned blocking component, the workpieces on the logistics transmission line can move or stop at the appropriate time, which can effectively solve the production rhythm problem of transferring the workpieces between multiple layers of horizontal transmission lines.

[0041] In some embodiments, the first transmission line includes at least one first horizontal transmission line, and the second transmission line includes a second horizontal transmission line. The blocking assembly is provided on each of the first horizontal transmission lines, or the blocking assembly is provided on the fixed component of each of the second horizontal transmission lines corresponding to the first horizontal transmission line. The triggering element is provided on each of the moving components of the second horizontal transmission line.

[0042] Due to the provision of the above-mentioned blocking component, the workpieces on the logistics transmission line can move or stop at the appropriate time, which can effectively solve the production rhythm problem of transferring the workpieces between multiple horizontal transmission lines on a layer.

[0065] Currently, new energy batteries are increasingly being used in everyday life and industry. They are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in a variety of fields such as aerospace. As the application of power batteries continues to expand, market demand is also growing.

[0066] In the embodiments of the present disclosure, the battery may be a battery cell. A battery cell refers to a basic unit that can realize the mutual conversion of chemical energy and electrical energy, and can be used to make a battery module or battery pack, thereby being used to supply power to an electrical device. The battery cell may be a secondary battery, which refers to a battery cell that can be recharged to activate the active material after the battery cell is discharged and continue to be used. The battery cell may be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-metal hydride battery, a nickel-cadmium battery, a lead-acid battery, etc., and the embodiments of the present disclosure are not limited to this.

[0067] In the production process of batteries, please refer to Figure 10. Pallets 5 are commonly used to support materials, which are transferred or stored between various processes through logistics transmission lines. In a certain production scenario, multiple layers of horizontal transmission lines 3 are arranged in the vertical direction. The vertical elevator 4 is a logistics transmission line in the vertical direction. The vertical elevator 4 can realize the transfer of the materials between the multiple layers of horizontal transmission lines 3. When the vertical elevator 4 is docked with a certain layer of horizontal transmission line 3, the blocking mechanism on the horizontal transmission line 3 releases the pallet 5; when the vertical elevator 4 is not docked with the horizontal transmission line 3, an electrical blocking system 6 is provided on the horizontal transmission line 3 to block the pallet 5. At the same time, a blocking mechanism is provided to block the pallet 5 when the electrical blocking system 6 fails to prevent it from falling. The vertical elevator 4 can transport materials upward or downward. Accordingly, the blocking mechanism needs to respond to the direction of movement of the vertical elevator 4, that is, to cooperate with the production rhythm of the vertical elevator 4.

[0068] In the present disclosure, "takt time" refers to the time required for each piece of equipment or process to complete a single cycle during the manufacturing process. The coordination of the takt times of each production line equipment or process ensures the smooth flow or processing of workpieces. Equipment failures or process capacity issues can result in lost or defective parts or unfinished products.

[0069] Based on the above considerations, an embodiment of the present disclosure provides a blocking mechanism 1. Referring to Figures 1 to 5, the blocking mechanism 1 includes a blocking assembly 10 and a trigger member 20. The blocking assembly 10 includes a transmission member 11, a blocking member 12, and an elastic member 13. The blocking member 12 has a first position in which it is blocked and a second position in which it is released. The trigger member 20 is capable of contacting the transmission member 11 in two opposite directions to place the blocking member 12 in the second position, and to cause the elastic member 13 to store elastic potential energy under the action of the transmission member 11, so that when the trigger member 20 is disengaged from the transmission member 11, the elastic member 13 can restore the blocking member 12 from the second position to the first position.

[0070] Taking the blocking mechanism 1 in Figures 1 and 5 as an example, the movement directions of the trigger member 20 are both represented by ν1 and ν2. The trigger member 20 can contact the transmission member 11 in two opposite directions, meaning that the trigger member 20 can contact the transmission member 11 in both directions, achieving bidirectional movement of the trigger member 20. For example, this can be left-right movement, front-back movement, or up-and-down movement. Specifically, the trigger member 20 in Figure 1 can move up and down, while the trigger member 20 in Figure 5 can move back and forth.

[0071] When the trigger member 20 moves to the specified position, it starts to push the transmission member 11. One end of the transmission member 11 contacts the trigger member 20, and the other end of the transmission member 11 is connected to the blocking member 12. The movement of the transmission member 11 drives the blocking member 12 to move.

[0072] The transmission member 11 and the trigger member 20 can be in contact connection, including by forming a rotation pair, a spherical pair or a moving pair to achieve transmission. The transmission member 11 and the blocking member 12 can be in contact connection, including by forming a rotation pair, a spherical pair or a moving pair to achieve transmission.

[0073] The elastic member 13 may be an elastic block or a spring, and the spring may include a tension spring, a compression spring or a torsion spring, etc. The elastic member 13 stores elastic potential energy, thereby providing a driving force capable of causing the transmission member 11 or the blocking member 12 to move in the opposite direction.

[0074] By pushing the transmission member 11 with the trigger member 20, the transmission member 11 drives the blocking member 12 to move, causing the blocking member 12 to reach the second position, thereby releasing the blocking. When the trigger member 20 is no longer in contact with the transmission member 11, the elastic member 13 returns the blocking member 12 to the first position, resuming the blocking. Because the trigger member 20 can contact the transmission member 11 in two opposing directions, workpieces such as the pallet 5 can be transferred between multiple layers of the conveyor line.

[0075] In some embodiments, referring to Figures 10 to 12, the trigger member 20 is disposed on the loading platform 41 of the vertical hoist 4, and the blocking assembly 10 is disposed on the frame of the horizontal transmission line 3 or on the fixed frame 42 of the vertical hoist 4, wherein the loading platform 41 is capable of moving up and down within the fixed frame 42. When the loading platform 41 of the vertical hoist 4 docks with the horizontal transmission line 3 from top to bottom or from bottom to top, the trigger member 20 reaches the designated position, applies a force to the transmission member 11, and the transmission member 11 pushes the blocking mechanism 1 to the second position to release the blockage, and the elastic member 13 stores elastic potential energy under the force of the transmission member 11. When the loading platform 41 of the vertical hoist 4 is not docked with the horizontal transmission line 3, that is, when the trigger member 20 is disengaged from the transmission member 11, the elastic potential energy of the elastic member 13 causes the blocking member 12 to return to the first position, and the blocking mechanism 1 establishes the blockage.

[0076] The blocking mechanism 1 of the embodiment of the present disclosure can be applied to a certain scenario in the battery production process, but it should not be understood that the application of the blocking mechanism 1 is limited to this scenario. The blocking mechanism 1 is further described below based on its application in the battery production process.

[0077] In some embodiments, referring to Figures 1 to 3 , the blocking assembly 10 further includes a base 14 , with the blocking member 12 rotatably connected to the base 14 . The transmission member 11 includes a push rod 111 , which is linearly movable relative to the base 14 . One end of the push rod 111 is connected to the blocking member 12 , and the other end of the push rod 111 is capable of contacting the trigger member 20 .

[0078] The base 14 supports the push rod 111 and the blocking member 12. The push rod 111 can move in a straight line relative to the base 14, and the blocking member 12 is rotatably connected to the base 14, so that the linear motion of the push rod 111 is converted into the rotation of the blocking member 12, thereby realizing the state change of the blocking member 12 between the first position and the second position.

[0079] In some embodiments, referring to FIG2 , the base 14 has a through hole 14A through which the push rod 111 passes. The through hole 14A restricts the push rod 111, allowing the push rod 111 to move linearly.

[0080] In some embodiments, referring to FIG. 4 , the base 14 includes a first base 143 and a second base 144. One of the first base 143 and the second base 144 has a slide rail, and the other of the first base 143 and the second base 144 has a slide groove. The first base 143 and the second base 144 slidably engage with each other via the slide rail and the slide groove. The blocking member 12 is rotatably connected to the first base 143, and the push rod 111 is fixedly connected to the second base 144. For example, the push rod 111 and the second base 144 may be integrally formed or connected via fasteners.

[0081] The slide rail and the slide groove are slidably engaged. For example, the first base 143 has a slide groove, and the second base 144 has a slide rail. The second base 144 can move linearly relative to the first base 143, and together with the push rod 111 fixed thereto, the push rod 111 can move linearly. The use of a slide rail and slide groove structure can effectively reduce production and maintenance costs.

[0082] In some embodiments, referring to FIG2 , the base 14 includes a base 141 and a linear bearing 142 , with the blocking member 12 rotatably connected to the base 141 . The linear bearing 142 is disposed on the base 141 and has a through hole 14A. The push rod 111 is disposed through the through hole 14A.

[0083] Linear bearing 142 is a bearing system used for linear motion. It is used in conjunction with a cylindrical shaft, such as push rod 111, and offers advantages such as low friction and high stability. Push rod 111 is inserted through hole 14A of linear bearing 142, which is mounted on base 141. When push rod 111 is moved by the force of trigger member 20, linear bearing 142 reduces friction losses, ensuring a longer lifespan and greater stability for blocking mechanism 1 during operation. The appropriate specifications and model of linear bearing 142 can be selected based on the force applied to push rod 111.

[0084] In some specific embodiments, please refer to Figure 2, the linear bearing 142 has a square cylindrical shell and is arranged on the seat body 141 by a snap or threaded connection. In other specific embodiments, please refer to Figure 7, the linear bearing 142 is cylindrical, and the seat body 141 has a mounting hole. The linear bearing 142 is connected to the seat body 141 through the mounting hole.

[0085] In some embodiments, referring to FIG. 2 , the seat body 141 includes a seat plate 1411 and an ear seat 1412. The linear bearing 1411 is disposed on the seat plate 1411. The ear seat 1412 is connected to the seat plate 1411 and includes a base plate 14121 and two first ear plates 14122 spaced apart from the base plate 14121. The blocking member 12 is located between the two first ear plates 14122 and is rotatably connected to the two first ear plates 14122. For example, the two first ear plates 14122 and the blocking member 12 are connected by a pin.

[0086] For ease of installation and maintenance, the seat body 141 can be divided into two removable parts: a seat plate 1411 and an ear seat 1412. For example, a gasket can be placed between the seat plate 1411 and the ear seat 1412 to adjust the rotation range of the blocking member 12. The two first ear plates 14122 sandwich the blocking member 12, and the blocking member 12 is rotatably connected to the two first ear plates 14122. Referring to Figure 7, for processing considerations, the seat plate 1411 and ear seat 1412 can also be integrally formed.

[0087] In some embodiments, referring to FIG. 2 , the transmission member 11 further includes a roller 112. The push rod 111 includes a rod body 1111 and a rod base 1112 connected to one end of the rod body 1111. The rod base 1112 includes two second lugs 11121 spaced apart from each other. The roller 112 is located between and rotatably connected to the two second lugs 11121. The roller 112 is configured to roll in contact with the trigger member 20. For example, the two second lugs 11121 and the roller 112 are connected by a pin.

[0088] Rolling friction can effectively reduce friction loss of materials and reduce frictional resistance. In some application scenarios, the production cycle can reach tens of thousands of times per day. The roller 112 can be made of metal or alloy to extend the life of the trigger member 20 and the transmission member 11.

[0089] In some specific embodiments, referring to FIG2 , the elastic member 13 is a compression spring, which is sleeved on the push rod 111 and located on the side of the base 14 away from the blocking member 12. For example, the compression spring is sleeved on the rod body 1111 and located between the rod seat 1112 and the base 14. The outer dimension of the rod seat 1112 projected along the axial direction of the rod body 1111 is larger than the inner diameter of the compression spring, thereby blocking the compression spring.

[0090] The compression spring is sleeved on the rod body 1111, between the rod seat 1112 and the base 14, which simplifies the installation of the compression spring. The two ends of the compression spring do not need to be connected to the rod seat 1112 and the base 14. The compression performance of the spring can reduce the vibration and impact of the blocking member 12 during operation, reduce noise, and reduce wear and damage between components, thereby extending the service life of the blocking mechanism 1.

[0091] The implementation cases of the elastic member 13 are not limited to the above-mentioned embodiments. For example, referring to FIG3 , the elastic member 13 may be a tension spring, which is sleeved on the push rod 111 and is located on the side of the base 14 close to the blocking member 12. For example, the tension spring is sleeved on the rod body 1111 and is located between the blocking member 12 and the base 14, and the two ends of the tension spring can be connected to the blocking member 12 and the base 14, respectively. When a linear bearing 142 is provided on the base 14, the two ends of the tension spring can be connected to the blocking member 12 and the linear bearing 142, respectively. When the transmission member 11 contacts the trigger member 20, the push rod 111 moves, the tension spring is stretched, and elastic potential energy is stored, causing the blocking member 12 to rotate to the second position. When the transmission member 11 is not in contact with the trigger member 20, the elastic force of the tension spring causes the push rod 111 to move in the opposite direction, and the blocking member 12 returns to the first position.

[0092] Referring to Figure 4 , the elastic member 13 can also be a torsion spring, disposed at the junction of the blocking member 12 and the base 14, for example, sleeved on a pin. The two torsion legs of the torsion spring abut against the blocking member 12 and the base 14, respectively. Rotation of the blocking member 12 causes the torsion spring to twist, storing elastic potential energy and providing a spring force capable of returning the blocking member 12 to the first position.

[0093] In some embodiments, the elastic member 13 is a rectangular spring.

[0094] Rectangular springs are made of a rectangular material with a cross-section that allows them to withstand high-speed vibrations, while also offering excellent stability and fatigue resistance. Depending on your production schedule, pallet mass, and transportation speed, you'll need to select the appropriate rectangular spring to meet your specific needs.

[0095] In some embodiments, referring to Figures 2 and 6 , the blocking member 12 includes a rotating portion 121 and a pushing portion 122. The rotating portion 121 is rotatably connected to the base 14. The pushing portion 122 has an escape groove 122A and an elongated hole 122B. The two escape grooves 122A are formed on either side of the pushing portion 122, and the elongated hole 122B connects the escape grooves 122A on both sides. One end of the push rod 111 is connected to the pushing portion 122 and can move along the elongated hole 122B.

[0096] The elongated hole 122B is provided on the pushing portion 122 to avoid the restriction of the degree of freedom when the linear movement of the push rod 111 is converted into the rotation of the blocking member 12. The avoidance groove 122A is provided on the pushing portion 122 to reduce the diameter of the push rod 111 and make the structure more compact.

[0097] In some embodiments, referring to FIG. 6 , the blocking member 12 includes a blocking surface 12A and an avoidance surface 12B. The blocking surface 12A faces away from the base 14 , and the avoidance surface 12B forms an angle with the blocking surface 12A, wherein the angle is less than 90 degrees.

[0098] Providing a relief surface 12B on blocking member 12 shortens the travel of transmission member 11, thereby reducing the rotation angle of blocking member 12 and enabling complete unblocking of blocking member 12 in the second position. When blocking member 12 is in the first position, blocking surface 12A blocks pallet 5. When blocking member 12 is in the second position, relief surface 12B reduces the height of blocking member 12 extending beyond horizontal conveyor line 3, allowing unblocked pallet 5 to pass smoothly.

[0099] 1 and 6 , the blocking member 12 includes a blocking surface 12A and a limiting surface 12C, wherein the blocking surface 12A faces away from the base 14 and the limiting surface 12C faces the base 14. When the blocking member 12 is in the first position, the limiting surface 12C abuts against the base 14.

[0100] In some application scenarios, when the blocking member 12 is in the first position, when the blocking member 12 is subjected to the force from the tray 5, the limiting surface 12C can limit the rotation stroke of the blocking member 12, and disperse the force to the abutment point between the limiting surface 12C and the base 14, thereby reducing the wear of the transmission member 11.

[0101] In some embodiments, please refer to Figure 2, the trigger part 20 includes a guide part 21 and a trigger part 22, and the two guide parts 21 are respectively located at the two ends of the trigger part 22, and the guide part 21 has a first guide end and a second guide end, the height of the first guide end is greater than the second guide end, and the first guide end is connected to the trigger part 22. The lowest height of the trigger part 22 can be equal to the highest height of the guide part 21. A smooth transition is formed between the contact surface of the guide part 21 for contacting the transmission part 11 and the contact surface of the trigger part 22 for contacting the transmission part 11. The above-mentioned "higher height" and "lower height" are relative to the mounting surface of the trigger part 20. The mounting surface of the trigger part 20 is used to install the trigger part 20 on other equipment, such as on the loading platform 41 of the vertical hoist 4.

[0102] When trigger member 20 reaches the designated position, guide portion 21 first contacts transmission member 11, and trigger member 20 begins to push transmission member 11. As trigger member 20 moves, trigger portion 22 smoothly switches to contact with transmission member 11. At this point, transmission member 11 moves to near its limit position, and blocking member 12 rotates to near the second position. In some applications, the height difference between the ends of guide portion 21 can be adjusted based on the inclination angle of avoidance surface 12B to control the travel of transmission member 11.

[0103] In some embodiments, referring to FIG2 , the contact surface of the guide portion 21 is a flat surface, while the contact surface of the trigger portion 22 is a convex arc surface. The convex arc surface of the trigger portion 22 can be tangent to the flat surface of the guide portion 21 to improve transmission smoothness. The contact surface of the trigger portion 22 can also be a flat surface, forming a smooth transition with the contact surface of the guide portion 21, thereby increasing the tolerance of the blocking mechanism 1 to transmission errors.

[0104] On the other hand, the present disclosure further provides a logistics transmission line, please refer to Figures 10 to 13, the logistics transmission line includes a first transmission line, a second transmission line and the blocking mechanism 1 in any of the above embodiments. The first transmission line and the second transmission line can both be used to transmit workpieces. In the following description, the workpiece is taken as an example of a pallet 5, but is not limited thereto. The first transmission line is used to transmit the pallet 5, and the second transmission line is used to transmit the pallet 5. The blocking assembly 10 of the blocking mechanism 1 is arranged on the fixed part of the first transmission line or the fixed part of the second transmission line, and the trigger member 20 is arranged on the moving part of the second transmission line. Among them, the blocking member 12 is in the first blocking position to prevent the pallet 5 from falling. The trigger member 20 can contact the transmission member 11 to make the blocking member 12 be in the second unblocking position, and the pallet 5 can move between the first transmission line and the second transmission line.

[0105] In some embodiments, referring to Figures 10 to 12 , the first transmission line comprises multiple layers of horizontal transmission lines 3, and the second transmission line comprises a vertical elevator 4. A blocking assembly 10 is provided on the mounting bracket 42 of the vertical elevator 4 at a location corresponding to each layer of horizontal transmission lines 3. In other embodiments, the blocking assembly 10 may also be provided on each layer of horizontal transmission lines 3.

[0106] In some embodiments, referring to FIG. 13 , the first transmission line includes at least one first horizontal transmission line 31, each of which is provided with a blocking assembly 10. The second transmission line includes a second horizontal transmission line 32, each of which has a trigger 20 provided on its moving components. In other embodiments, the blocking assembly 10 may also be provided on the fixed components of the second horizontal transmission line 32 corresponding to each of the first horizontal transmission lines 31.

[0107] Due to the provision of the blocking mechanism 1 in any of the above embodiments, the pallets 5 on the logistics transmission line move or stop at the appropriate time, which can effectively solve the production rhythm problem of transferring pallets 5 between multiple horizontal transmission lines in a layer and / or between multiple layers of horizontal transmission lines.

[0108] For example, referring to Figure 10, the horizontal conveyor line 3 has multiple layers, spaced apart in the vertical direction. The vertical elevator 4 is located at one end of the horizontal conveyor line 3 and has a moving component for carrying a pallet 5, such as a loading platform 41. In some application scenarios, when the loading platform 41 docks with the horizontal conveyor line 3 on the third layer, the blocking mechanism 1 is unblocked, and the pallet 5 on the horizontal conveyor line 3 on the third layer is transferred to the loading platform 41; when the loading platform 41 docks with the horizontal conveyor line 3 on the second layer from top to bottom, the blocking mechanism 1 is unblocked, and the pallet 5 is transferred from the loading platform 41 to the horizontal conveyor line 3 on the second layer. In some application scenarios, when the loading platform 41 docks with the horizontal conveyor line 3 on the second layer, the blocking mechanism 1 is unblocked, and the pallet 5 on the horizontal conveyor line 3 on the second layer is transferred to the loading platform 41; when the loading platform 41 docks with the horizontal conveyor line 3 on the third layer from bottom to top, the blocking mechanism 1 is unblocked, and the pallet 5 is transferred from the loading platform 41 to the horizontal conveyor line 3 on the third layer. In some application scenarios, the pallet 5 is transferred from the horizontal conveyor line 3 to the loading platform 41 of the vertical elevator 4, and then transported to other workstations; or, the pallet 5 is transferred from the loading platform 41 of the vertical elevator 4 to the horizontal conveyor line 3.

[0109] For example, referring to Figure 13 , there are multiple first horizontal conveyor lines 31 arranged horizontally, and a second horizontal conveyor line 32 is arranged perpendicular to the first horizontal conveyor line 31 and has a moving component, such as a loading platform 41, that carries a tray 5. In some application scenarios, when the loading platform 41 docks with the first first horizontal conveyor line 31, the blocking mechanism 1 is released, and the tray 5 on the first first horizontal conveyor line 31 is transferred to the loading platform 41; when the loading platform 41 docks with the second first horizontal conveyor line 31 from front to back, the blocking mechanism 1 is released, and the tray 5 is transferred from the loading platform 41 to the second first horizontal conveyor line 31. In some application scenarios, when the loading platform 41 docks with the second first horizontal conveyor line 31, the blocking mechanism 1 is released, and the pallet 5 on the second first horizontal conveyor line 31 is transferred to the loading platform 41. When the loading platform 41 docks with the first first horizontal conveyor line 31 from back to front, the blocking mechanism 1 is released, and the pallet 5 is transferred from the loading platform 41 to the first first horizontal conveyor line 31. In some application scenarios, the pallet 5 is transferred from the first horizontal conveyor line 31 to the loading platform 41 of the second horizontal conveyor line 32 and then transported to another workstation; alternatively, the pallet 5 is transferred from the loading platform 41 of the second horizontal conveyor line 32 to the first horizontal conveyor line 3.

[0110] It is understandable that the transport direction is not limited to the vertical or horizontal direction in the above embodiments, and the installation positions of the various components of the blocking mechanism 1 can be adjusted in a timely manner according to production needs.

[0111] The above-mentioned logistics transmission line has various uses, including the flow of semi-finished products in production line processes, the distribution of products from the parts workshop to the assembly workshop, and the storage or release of finished products in the warehouse. Referring to Figure 10, in some application scenarios, a blocking assembly 10 is provided at one end of the fixed frame 42 of the vertical elevator 4 corresponding to each horizontal transmission line 3. An electrical blocking system 6 is provided upstream of the blocking assembly 10 corresponding to each horizontal transmission line 3. The electrical blocking system 6 may include a light sensor, a lifting cylinder, and a control computer. The control computer adjusts various system parameters. When the light sensor recognizes that the pallet 5 is approaching and the vertical elevator is not in place, the lifting cylinder is activated to block the pallet 5 until the vertical elevator 4 is in place. Due to the life of the lifting cylinder or the sensitivity of the light sensor, the electrical blocking system 6 may be unstable and unable to block the pallet 5 in time. The blocking mechanism 1 provided in the present disclosure serves as another line of defense to prevent the pallet 5 from falling from the logistics transmission line, thereby enhancing the stability of the logistics transmission line during operation and providing a guarantee for operational safety.

[0112] In some application scenarios, the blocking mechanism 1 is in direct contact with the pallet 5 and is the first line of defense for blocking the pallet 5. The blocking member 12 is in high-frequency contact with the pallet 5. The material properties or dimensional relationship of the blocking mechanism 1 can be changed according to actual production conditions to improve durability and stability.

Although the present disclosure has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present disclosure, and they should be included in the scope of the specification of the present disclosure.
