Description

Technical Field

[0001] This application relates to the field of conveying technology, and in particular to a material conveying device. Background Technology

[0002] In the fields of automated logistics and intelligent manufacturing, the collaborative picking technology of AGVs (Automated Guided Vehicles) and transport machines has become one of the core solutions for improving material handling efficiency, and is widely used in e-commerce warehousing, automotive parts processing, electronic component production and other scenarios.

[0003] Although the technology of AGV and conveyor co-retrieval has been widely used, for easily deformable materials such as thin metal sheets and flexible packaging, AGVs are prone to pushing the materials off course during retrieval, causing the materials to back up, retrieval failure, and even material damage, affecting the continuity and safety of the conveying process. Utility Model Content

[0004] This application provides a material conveying device that helps to prevent material from backing up and reduces the possibility of failure to pick up goods.

[0005] This application provides a material conveying device, which includes a transmission mechanism and a one-way limiting mechanism.

[0006] The transmission mechanism includes multiple support brackets and a transmission component. The multiple support brackets are spaced apart along a first horizontal direction. The support brackets are provided with mounting grooves. The transmission component is rotatably connected to the support brackets. At least a portion of the transmission component is located in the mounting groove. The support brackets include an input end and an output end that are arranged opposite to each other along a second horizontal direction. The first horizontal direction is perpendicular to the second horizontal direction.

[0007] The one-way limiting mechanism is detachably connected to the bearing bracket, and the one-way limiting mechanism includes a stop and a first limiting member.

[0008] The stop is rotatably connected to the support bracket. The stop includes a stop end and a limiting end. The stop end is located outside the mounting groove, and the limiting end is located inside the mounting groove. The center of gravity of the stop is eccentrically set with respect to its horizontal rotation axis, and is located below the horizontal rotation axis.

[0009] The first limiting member is connected to the support bracket. At least a portion of the first limiting member is disposed in the mounting groove. The first limiting member is disposed on the side of the limiting end near the output end. The first limiting member is used to restrict the limiting end from rotating toward the output end.

[0010] In the material conveying device of this application embodiment, a stop member is rotatably connected to the support bracket. When the material is transported from the input end to the output end, the material can push the stop member to rotate through the end of the stop member so that the end of the stop member can avoid the material. At this time, the stop member will not obstruct the transported material, and the material can be transported smoothly to the output end.

[0011] The center of gravity of the stop is located below the horizontal rotation axis, making it eccentric relative to the axis. When transported material passes over the stop, its center of gravity, being below the axis, allows it to return to a vertical position under its own weight, causing the stop end to extend out of the mounting groove and block the reversing material. In this embodiment, no additional drive device is needed to rotate the stop, reducing the number of components and assembly difficulty.

[0012] By setting a stop and positioning its end outside the mounting groove, and simultaneously providing a first limiting member to restrict the limiting end from rotating towards the output end, when the material being transported by the conveying mechanism reverses during the picking process, the first limiting member restricts the limiting end from rotating towards the output end. The stop end, located outside the mounting groove, blocks the backward-moving material, reducing the possibility of picking failure. Furthermore, by detachably connecting the one-way limiting mechanism to the support bracket, the position of the stop can be adjusted according to the size of the transported material, reducing the possibility of the material reversing too far, minimizing the risk of material damage, and improving the transport efficiency of the material conveying device.

[0013] In some feasible embodiments, the support bracket includes a connecting base and a support member, the support member being disposed at the bottom of the connecting base, the connecting base being provided with a mounting groove, a stop member being rotatably connected to the connecting base, and a first limiting member being connected to the connecting base.

[0014] In some feasible implementations, the one-way limiting mechanism also includes a connector connected to a connecting base, a stop rotatably connected to the connector, and the connector positioned above the first limiting member in the vertical direction.

[0015] In some feasible implementations, the vertical distance between the central axis of the connector and the central axis of the first limiting member is greater than zero along the second horizontal direction.

[0016] In some feasible implementations, the stop includes two side plates spaced apart along a first horizontal direction, the two side plates being rotatably connected to the connector.

[0017] In some feasible configurations, the stop end extends beyond the side plate in the vertical direction, and the side plate extends to the limiting end.

[0018] In some feasible implementations, a second limiting element is provided between the side plate and the connecting base, and there is a gap between the side plate and the connecting base along a first horizontal direction.

[0019] In some feasible implementations, there is a gap between the limiting end and the connecting base in the vertical direction.

[0020] In some feasible embodiments, the transmission element includes multiple transmission rollers spaced apart in a mounting groove along a first horizontal direction, with a stop element disposed between two adjacent transmission rollers.

[0021] In some feasible implementations, there is a clearance distance between two adjacent drive rollers and the stop for avoiding the stop. Attached Figure Description

[0046] See Figures 1 to 3 As shown in the figure, this application provides a material conveying device, which includes a transmission mechanism 1 and a one-way limiting mechanism 2.

[0047] The transmission mechanism 1 includes multiple support brackets 11 and transmission components 12. The multiple support brackets 11 are spaced apart along the first horizontal direction X. The support brackets 11 are provided with mounting grooves 110. The transmission components 12 are rotatably connected to the support brackets 11. At least a portion of the transmission components 12 is located in the mounting grooves 110. The support brackets 11 include an input end 1101 and an output end 1102 that are arranged opposite each other along the second horizontal direction Y. The first horizontal direction X is perpendicular to the second horizontal direction Y.

[0048] The one-way limiting mechanism 2 is detachably connected to the support bracket 11. The one-way limiting mechanism 2 includes a stop member 21 and a first limiting member 22. The stop member 21 is rotatably connected to the support bracket 11. The stop member 21 includes a stop end 211 and a limiting end 212. The stop end 211 is located outside the mounting groove 110, and the limiting end 212 is located inside the mounting groove 110. The center of gravity of the stop member 21 is eccentrically set with respect to the horizontal rotation axis of the stop member 21, and the center of gravity of the stop member 21 is located below the horizontal rotation axis.

[0049] The first limiting member 22 is connected to the bearing bracket 11. At least a portion of the first limiting member 22 is disposed in the mounting groove 110. The first limiting member 22 is disposed on the side of the limiting end 212 near the output end 1102. The first limiting member 22 is used to restrict the limiting end 212 from rotating toward the output end 1102.

[0050] The conveying mechanism 1 is used to support materials. Materials can be temporarily stored in the conveying mechanism 1. The picking equipment can then retrieve the materials from the conveying mechanism 1.

[0051] In some feasible implementations, a one-way limiting mechanism 2 is installed on each support bracket 11. All one-way limiting mechanisms 2 installed on each support bracket 11 are arranged correspondingly to each other along the first horizontal direction X. The spacing between the support brackets 11 and the distance between the one-way limiting mechanism 2 and the output end 1102 are adjusted according to the size of the transported material.

[0052] When material is transported from input end 1101 to output end 1102, after the material comes into contact with the stop end 211, the material can push the stop member 21 to rotate through the stop end 211. The limiting end 212 of the stop member 21 rotates towards the input end 1101, and the stopping end 211 of the stop member 21 gradually moves under the material to avoid it. The transported material slides over the stopping end 211 of the stop member 21. After the transported material slides over the stopping end 211 of the stop member 21, the stop member 21 returns to the vertical direction under its own weight, and the stopping end 211 extends out of the mounting groove 110 again. The limiting end 212 abuts against the first limiting member 22, so that the stop member 21 can be used to block the material. When the material moves backward from the output end 1102 to the input end 1101, after the material comes into contact with the stop end 211, the stop end 211 can limit and constrain the material, so that the material stops moving backward.

[0053] When the material retreats towards the input end 1101 and comes into contact with the stop end 211, the first limiting member 22 restricts the limiting end 212 from rotating towards the input end 1101. Therefore, the limiting end 212 cannot rotate around the horizontal rotation axis towards the output end 1102, which in turn prevents the stop end 211 from rotating around the horizontal rotation axis towards the input end 1101. The stop end 211 blocks the retreating material, preventing it from passing through the stop member 21. This means that the material can only pass through the transmission mechanism 1 unidirectionally from the input end 1101 to the output end 1102.

[0054] In the material conveying device of this application embodiment, a stop member 21 is rotatably connected to the support bracket 11. When the material is transported from the input end 1101 to the output end 1102, the material can push the stop member 21 to rotate through the stop end 211 so that the stop end 211 can avoid the material. At this time, the stop member 21 will not obstruct the transported material, and the material can be smoothly transported to the output end 1102.

[0055] The center of gravity of the stop 21 is located below the horizontal rotation axis, making it eccentric relative to the horizontal rotation axis. When the transported material passes over the stop 21, because its center of gravity is below the horizontal rotation axis, the stop 21 can return to the vertical direction under its own weight, causing the stop end 211 to extend out of the mounting groove 110 again, thus blocking the backward movement of material. In this embodiment, there is no need for an additional drive device to drive the stop 21 to rotate, which helps reduce the number of parts used and the assembly difficulty.

[0056] By setting a stop 21 and positioning the stop end 211 outside the mounting groove 110, and simultaneously setting a first limiting member 22 to restrict the limiting end 212 from rotating toward the output end 1102, when the material being transported by the conveying mechanism 1 moves backward during the picking process, the first limiting member 22 restricts the limiting end 212 from rotating toward the output end 1102. The stop end 211, located outside the mounting groove 110, blocks the backward-moving material, reducing the possibility of picking failure. Furthermore, by setting a one-way limiting mechanism 2 that is detachably connected to the bearing bracket 11, the position of the stop 21 can be adjusted according to the size of the transported material, reducing the possibility of the material moving backward too far, reducing the possibility of material damage, and improving the transport efficiency of the material conveying device.

[0057] In some feasible ways, such as Figure 1 As shown, the support bracket 11 includes a connecting base 111 and a support member 112. The support member 112 is disposed at the bottom of the connecting base 111. The connecting base 111 is provided with a mounting groove 110. The stop member 21 is rotatably connected to the connecting base 111. The first limiting member 22 is connected to the connecting base 111.

[0058] By setting a support member 112 at the bottom of the connecting base 111, the support member 112 makes the transported material a certain distance from the ground, thereby facilitating the automatic guided vehicle to receive and transport the material from the transmission mechanism 1.

[0059] In some implementations, the connecting base 111 includes two mounting plates spaced apart along a first horizontal direction X, forming a mounting groove 110 between the two mounting plates. Multiple through holes are provided on the mounting plates, communicating with the mounting groove 110. The stop member 21 and the transmission member 12 are detachably connected to the mounting plates through the through holes. This allows the stop member 21 and the transmission member 12 to adjust the distance between the stop member 21 and the output end 1102 according to the size of the transported material, reducing the possibility of damage to the reversing material due to excessive reversal distance.

[0060] In some feasible ways, the support 112 and the connecting base 111 can be connected by bolts, but not limited to.

[0061] In some feasible ways, such as Figure 2 As shown, the one-way limiting mechanism 2 also includes a connector 23, which is connected to the connecting base 111. The stop 21 is rotatably connected to the connector 23. In the vertical direction, the connector 23 is located above the first limiting member 22.

[0062] In some possible implementations, the connecting base 111 includes two mounting plates spaced apart along a first horizontal direction X. The mounting plates have multiple through holes. One end of the connector 23 is threaded to one mounting plate through a through hole, and the other end passes through a stop member 21 and is threaded to the other mounting plate. Both ends of the connector 23 extend beyond the two mounting plates and are connected to fixing nuts.

[0063] The connector 23 is provided with threads, and the connection between the stop 21 and the connector 23 is also provided with threads. The threads of the connector 23 and the threads of the stop 21 are matched, so that the stop 21 can rotate around the connector 23.

[0064] By rotatably connecting the connector 23 and the stop 21, the stop 21 can rotate around the connector 23 during the process of transporting material from the input end 1101 to the output end 1102, allowing the transported material to pass smoothly through the stop 21. Furthermore, after the transported material has successfully passed through the stop 21, the stop 21 can rotate around the connector 23 under the influence of gravity, returning the stop 21 to its initial state.

[0065] In the initial state, the stop end 211 is above the limit end 212 in the vertical direction, and the stop end 211 is located outside the mounting groove 110.

[0066] In some feasible ways, connector 23 may be, but is not limited to, a stud.

[0067] In some feasible ways, such as Figure 4 and Figure 5 As shown, along the second horizontal direction Y, the vertical distance between the central axis of the connector 23 and the central axis of the first limiting member 22 is greater than zero. The central axis of the first limiting member 22 is relatively close to the output end 1102.

[0068] Along the second horizontal direction Y, by setting the vertical distance between the central axis of the connector 23 and the central axis of the first limiting member 22 to be greater than zero, when the stop member 21 is not subjected to external force, the stop member 21 can be relatively easily kept in the vertical direction instead of being in an inclined state.

[0069] In some feasible ways, such as Figure 2 As shown, the stop member 21 includes two side plates 213 spaced apart along the first horizontal direction X, and the two side plates 213 are rotatably connected to the connector 23.

[0070] In some feasible ways, along the first horizontal direction X, two side plates 213 spaced apart on the stop member 21 can increase the weight of the stop member 21 and facilitate the connection between the stop member 21 and the connector 23.

[0071] In some feasible ways, such as Figures 2 to 5 As shown, along the vertical direction, the stop end 211 extends beyond the side plate 213, and the side plate 213 extends to the limiting end 212.

[0072] In the vertical direction, by not setting side edges on both sides of the stop end 211, the weight of the stop end 211 can be reduced. By setting side plates 213 on both sides of the limiting end 212, the side plates 213 can increase the weight at the limiting end 212, causing the center of gravity of the stop 21 to shift downward. When there is no external force acting on the stop 21, the state in which the stop end 211 is above and the limiting end 212 is below can be relatively easily achieved in the vertical direction under the action of gravity.

[0073] In some feasible ways, such as Figure 2 As shown, a second limiting member 24 is provided between the side plate 213 and the connecting base 111, and there is a gap between the side plate 213 and the connecting base 111 along the first horizontal direction X.

[0074] The second limiting member 24 can limit the stop member 21, so that there is a gap between the side plate 213 and the connecting base 111 along the first horizontal direction X, reducing the possibility of contact and friction or scratch between the side plate 213 and the connecting base 111.

[0075] In some feasible methods, the stop 21 is adjusted to a suitable position along the first horizontal direction X according to the size of the transported material, and the position of the stop 21 is fixed by the second limiting member 24.

[0076] In some possible implementations, the second limiting member 24 is connected to the connecting member 23. The second limiting member 24 may be, but is not limited to, a nut. The second limiting member 24 is threadedly connected to the connecting member 23.

[0077] In some feasible ways, such as Figure 5 As shown, there is a gap between the limiting end 212 and the connecting base 111 in the vertical direction.

[0078] In some feasible ways, by having a gap between the limiting end 212 and the connecting base 111, when the limiting end 212 is rotating, the connecting base 111 will not block the limiting end 212, ensuring that the stop 21 can rotate normally, while reducing the possibility of contact and friction or scratching between the limiting end 212 and the connecting base 111.

[0079] In some feasible ways, such as Figure 1 and Figure 3As shown, the transmission component 12 includes multiple transmission rollers, which are spaced apart in the mounting groove 110 along the first horizontal direction X, and the stop component 21 is disposed between two adjacent transmission rollers.

[0080] In some feasible implementations, the drive rollers are detachably connected to the connecting base 111. Before transporting materials, the spacing between the drive rollers is adjusted according to the size of the materials to accommodate the support requirements of materials of different sizes. For larger materials, widening the spacing between the drive rollers avoids excessively dense arrangement of the rollers, which helps reduce running resistance and ensures uniform force distribution on the bottom of the material. For smaller materials, narrowing the spacing between the drive rollers prevents materials from falling or getting stuck in the gaps between the rollers, ensuring smooth conveying. Setting up multiple drive rollers can achieve material transport without deviation or collision, improving conveying stability and safety, while also enhancing the adaptability of the conveying mechanism 1 to materials of multiple specifications and improving overall transport efficiency.

[0081] In some feasible ways, such as Figure 4 As shown, there is a clearance distance between two adjacent drive rollers and the stop 21 for avoiding the stop 21.

[0082] In some feasible implementations, the drive rollers need to rotate continuously to transport materials. In the transmission mechanism 1, a clearance distance is provided between adjacent drive rollers and the stop 21 to avoid mechanical interference between the drive rollers and the stop 21 during operation. This reduces the possibility of friction or jamming between the drive rollers and the stop 21, which could lead to component damage or affect the normal operation of the drive rollers. Simultaneously, when the stop 21 rotates, this clearance ensures that the stop 21 does not contact the drive rollers, further reducing the possibility of friction or jamming after contact between the drive rollers and the stop 21, which could lead to component damage or affect the normal operation of the drive rollers.

[0083] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
