Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical spider arm technology, and in particular to a belt conveyor-assisted spider arm loading device. Background Technology
[0002] In belt conveyor systems, the spider arm is a key automated device that connects goods on the ground to the belt. With the help of the spider arm, goods can be easily moved onto the belt. In the early days, manual handling was inefficient and physically demanding. During the constant speed conveying of the belt, goods could not be moved onto the belt in time, resulting in reduced belt utilization and failure to meet the needs of large-scale production.
[0003] To meet the demands of large-scale production, robotic spider arms are equipped at the loading end of conveyor belts to accelerate the transfer of goods from the ground to the belt. However, in actual use, the spider arm, as a cooperating loading arm, primarily alleviates the physical exertion and low efficiency of manual handling. While using high-precision multi-axis robotic spider arms can solve the problems of high physical exertion and low efficiency in manual handling, it also increases production and maintenance costs. The complex structure increases the difficulty of subsequent maintenance and significantly reduces its ease of maintenance. Therefore, we propose a conveyor belt assisting spider arm loading device with a simple structure, stable clamping force, and convenient maintenance. Utility Model Content
[0004] The purpose of this invention is to address the problems of complex structure and high maintenance cost in the prior art by proposing a belt conveyor assisting spider arm loading device with simple structure, stable clamping force, and convenient maintenance.
[0005] The technical solution of this utility model: a belt conveyor assisting a spider arm in loading, including a suspension plate, a flange seat fixedly installed at the top of the suspension plate, and the top of the flange seat fixedly connected to an external robotic arm, and further including:
[0006] The support arm has several arms arranged in a ring and fixed to the bottom of the suspension plate. A clamping arm is rotatably mounted on the support arm. A second cylinder is fixedly mounted on the support arm, and the output end of the second cylinder is movably connected to the top of the support arm.
[0007] A suspension arm is fixedly mounted on one end of a support arm, and a first cylinder is fixedly mounted on the suspension arm. The output end of the first cylinder is movably connected to the bottom of the clamping arm.
[0008] Optionally, the support arm has an adjustment opening, a positioning shaft that passes through the adjustment opening is fixedly installed on the support arm, and a circular through hole is drilled on the clamping arm. One end of the positioning shaft passes through the circular through hole and is movably connected to it.

[0028] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0029] Example
[0030] like Figure 1 As shown, the belt conveyor-assisted spider arm loading device proposed in this utility model includes a suspension plate 1. A flange seat 2 is fixedly mounted on the top of the suspension plate 1, and the end of an external robotic arm is fixedly connected to the flange seat 2 as a whole. The robotic arm drives the spider arm to move in multiple axes, which facilitates the clamping and handling of goods. Several ring-shaped support arms 3 are fixedly installed at the bottom of the suspension plate 1. A clamping arm 4 is rotatably mounted on the support arm 3. A second cylinder 7 is fixedly installed on the support arm 3. The output end of the second cylinder 7 is movably connected to the top of the clamping arm 4. The second cylinder 7 pushes the top of the clamping arm 4. The clamping arm 4 can be rotated and adjusted to ensure that the bottom end of the clamping arm 4 can approach the goods. When the bottom ends of multiple clamping arms 4 are in close contact with the goods, the goods can be gripped. A suspension arm 33 is fixedly installed at one end of the support arm 3. A first cylinder 5 is fixedly installed on the suspension arm 33. The output end of the first cylinder 5 is movably connected to the bottom of the clamping arm 4. During the rotation and adjustment of the clamping arm 4, the bottom end of the clamping arm 4 is pushed to move towards the goods by the first cylinder 5, ensuring that the bottom end of the clamping arm 4 can be in close contact with the goods, effectively enhancing the clamping force and improving the stability when gripping the goods.
[0031] like Figures 1-3As shown, in order to improve the stability of the rotatable connection between the clamping arm 4 and the support arm 3, an adjustment opening 31 is drilled on the support arm 3, and a positioning shaft 32 is fixedly installed on the support arm 3. One end of the positioning shaft 32 passes through the adjustment opening 31. A circular through hole 41 is drilled on the clamping arm 4, and one end of the positioning shaft 32 passes through the circular through hole 41 and is movably connected to it. The clamping arm 4 can be rotatably installed on the support arm 3 through the positioning shaft 32, which effectively improves its stability after installation.
[0032] Furthermore, in order to increase the friction between the bottom end of the gripping arm 4 and the contact surface of the goods, a rubber block 6 is fixedly installed on the inner wall of the gripping arm 4. The rubber block 6 is installed at the end away from the second cylinder 7. When the bottom ends of multiple gripping arms 4 are in contact with the goods, the rubber block 6 is in close contact with the goods, which can increase the friction between the contact surface of the goods and improve the stability of gripping.
[0033] like Figures 1-5 As shown, in order to facilitate pushing the top of the clamping arm 4, the push rod 711 on the second push frame 71 is fixedly installed at the output end of the second cylinder 7. The second cylinder 7 can drive the second push frame 71 to move laterally. A limit opening 42 is drilled on the clamping arm 4. One end of the push rod 711 passes through the limit opening 42 and is movably connected to it, so that the output end of the second cylinder 7 can form a soft connection with the clamping arm 4. When the second push frame 71 moves laterally, it can drive the clamping arm 4 to rotate stably.
[0034] Furthermore, in order to enable the push rod 711 to stably push the top of the clamping arm 4, two second rollers 712 are rotatably installed on the two outer side walls of the push rod 711. The four second rollers 712 are divided into two groups, each group consisting of two second rollers 712. A group of second rollers 712 is distributed on both sides of the opening of the aforementioned limiting opening 42. When the push rod 711 moves laterally, the two second rollers 712 near the side of the second cylinder 7 can provide a stable thrust to the push rod 711, ensuring that the push rod 711 can stably push the top of the clamping arm 4.
[0035] Secondly, when it is necessary to put the goods onto the belt, the push rod 711 is pulled back to its original position by the second cylinder 7. At this time, the two second rollers 712 on the side away from the second cylinder 7 provide pulling force for the push rod 711, which facilitates the reverse adjustment of the clamping arm 4, ensuring that the bottom end of the clamping arm 4 is away from the goods, so that the goods can be released and put onto the belt.
[0036] It is worth noting that, in order to improve the stability of the gripping arm 4 when gripping goods, the U-shaped bracket 511 installed on the first push frame 51 is fixedly assembled at the output end of the first cylinder 5. The first roller 512 is rotatably installed on the U-shaped bracket 511. A limiting groove 43 is chiseled on the outer wall of the gripping arm 4. One end of the first roller 512 is embedded in the limiting groove 43 and movably connected to it. When the bottom end of the gripping arm 4 rotates towards the goods, the first push frame 51 is pushed laterally towards the goods by the first cylinder 5. At this time, the first roller 512 rolls upward inside the limiting groove 43, which can provide a pushing force towards the goods for the bottom end of the gripping arm 4, increase the gripping force of the goods, and effectively improve the stability of the gripping arm 4 when gripping goods.
[0037] In this embodiment, the flange seat 2 is first fixedly mounted on the external robotic arm. The robotic arm drives the spider arm to perform multi-axis movements, facilitating the transfer of gripped goods onto the conveyor belt, reducing manual labor consumption, and improving the efficiency of goods handling. When it is necessary to grip the goods, the second cylinder 7 pushes the top of the gripping arm 4 to move away from the suspension plate 1. Under the soft connection of the second push frame 71, the gripping arm 4 can be rotated and adjusted around the positioning shaft 32, facilitating the adjustment of the bottom end of the gripping arm 4 to the side of the goods. When the rubber block 6 is in close contact with the outside of the goods, the goods can be gripped by multiple gripping arms 4. During the process, the first cylinder 5 pushes the first pusher 51 towards the cargo side. At this time, the first roller 512 can provide a pushing force towards the cargo at the bottom of the gripping arm 4, increasing the gripping force and improving the stability when gripping the cargo. After the cargo is transported above the belt, the second cylinder 7 drives the second pusher 71 to move towards the suspension plate 1 side. At this time, the first cylinder 5 drives the first pusher 51 to move away from the cargo, and then rotates and resets the gripping arm 4 to ensure that the bottom of the gripping arm 4 can move away from the cargo, so that the cargo can be released and placed on the belt. This spider hand has a simple structure, stable gripping force, and is convenient for later maintenance.
[0038] The above specific embodiments are merely several optional embodiments of this utility model.
