Description

Technical Field

[0001] The invention belongs to the technical field of suspension conveying systems, and in particular relates to a step-by-step suspension conveying vehicle releasing device. Background Art

[0002] The suspension conveying system can make full use of the three-dimensional space and meet the requirements of effective transportation in a limited space. It is a flexible and highly automated advanced conveying equipment, which plays an increasingly important role in modern large-scale production. The suspension conveying system can freely select the conveying route, effectively utilize space, save manpower, and improve work efficiency. Its structure is mainly composed of components such as chains, rails, hangers, brackets, transmission seats and adjustment seats. It can be widely used in long-distance conveying of workpieces, floor lifting, aerial storage, feeding and other processes and automated production lines.

[0003] At present, the suspended conveyor system uses ramps to cache by gravity according to product characteristics, weight and cost. In the process of large-scale caching, when multiple conveyor vehicles are cached together and released, it is easy for the front vehicle to be released and the rear vehicle to follow, resulting in failure to release one by one or even blockage. Therefore, a step-by-step suspended conveyor vehicle release device is needed to ensure that the conveyor vehicles are released one by one in an orderly manner. Summary of the invention

[0004] Purpose of the invention: In order to overcome the above shortcomings, the purpose of the present invention is to provide a step-by-step suspended transport vehicle release device, which has a simple structure and can give the transport vehicle a certain initial velocity through the cylinder during the release process to ensure that the transport vehicle can overcome the static friction and start from a stationary state, and solves the problem that the following vehicle cannot be released one by one during the release process.

[0005] Technical solution: A step-by-step suspended transport vehicle release device, comprising a track, a transport vehicle, and a release mechanism, wherein a plurality of transport vehicles are arranged in parallel on the track, and the release mechanism comprises a cylinder, a connecting rod 1, a blocking rocker arm 1, a release rocker arm, and a blocking rocker arm 2. One end of the cylinder is hinged to a mounting plate fixed on the track, and the other end is an output end connected to a connecting shaft arranged on the connecting rod 1. One end of the connecting rod 1 is rotatably connected to a release rocker arm, and the other end is rotatably connected to a blocking rocker arm 1. The end of the release rocker arm away from the connecting rod 1 is rotatably connected to the connecting rod 2, and the other end of the connecting rod 2 is rotatably connected to the blocking rocker arm 2. A rotating shaft is fixed on the blocking rocker arm 1, the release rocker arm, and the blocking rocker arm 2, and the rotating shaft is rotatably connected to the track. The blocking rocker arm 1, the release rocker arm, and the blocking rocker arm 2 cooperate with the load-bearing shaft on the transport vehicle. In the cache state, the cylinder is in the extended state, and the blocking rocker arm 1 blocks the conveyor vehicle from moving forward; when the conveyor vehicle needs to be released, the cylinder retracts, and the blocking rocker arm 1 opens. At the same time, the cylinder drives the release rocker arm to hit the load-bearing shaft of the front vehicle of the conveyor vehicle to give the conveyor vehicle a certain initial velocity so that the conveyor vehicle is accelerated and released. At the same time, the blocking rocker arm 2 blocks the rear vehicle of the conveyor vehicle. After the first conveyor vehicle is completely released, the device is reset to the cache state, and the rear vehicle is transported to the end of the device by gravity, and released one by one in this cycle.

[0006] Furthermore, in the above-mentioned step-type suspended conveyor vehicle releasing device, the releasing mechanism also includes a buffer spring, and a joint bearing is connected to the cylinder piston rod. The joint bearing can withstand loads in all directions, reduce the load, and reduce the difficulty of installation. The buffer spring is sleeved on the outside of the joint bearing and the cylinder piston rod. The buffer spring can provide buffering force for the movement of the cylinder, making the equipment run more stably.

[0007] Furthermore, in the above-mentioned step-type suspended transport vehicle release device, a limit plate is provided at the transition between the rod and the connection of the joint bearing, one end of the spring abuts against the limit plate, and the other end abuts against the end surface of the cylinder. By setting the limit plate, the buffering force of the spring is concentrated in the direction of the central axis of the piston rod, and the buffering effect is better.

[0008] Furthermore, in the above-mentioned step-by-step suspended transport vehicle release device, the blocking rocker arm 1, the release rocker arm, and the blocking rocker arm 2 are all V-shaped rods, and the rotating shaft is arranged at the middle position of the turning point of the V-shaped rod. This arrangement makes the rotation of the blocking rocker arm 1, the release rocker arm, and the blocking rocker arm 2 more stable.

[0009] Furthermore, in the above-mentioned step-type suspended transport vehicle release device, a rotating sleeve is provided on the outer side of the rotating shaft, and the rotating sleeve is fixed to a mounting plate provided on the track by welding. The rotating sleeve supports the first blocking rocker arm, the release rocker arm, and the second blocking rocker arm so that they rotate around the rotating sleeve to ensure accurate and stable rotation.

[0010] Furthermore, in the above-mentioned step-by-step suspended conveyor vehicle releasing device, a buffer block is provided at one end of the blocking rocker arm away from the connecting rod, and the buffer block buffers the buffer force when the conveyor vehicle stops, thereby reducing the impact on the conveyor vehicle and the objects conveyed on the conveyor vehicle. The buffer block is made of elastic plastic, which is low in price and has a good buffering effect.

[0011] It can be seen from the above technical scheme that the present invention has the following beneficial effects: the step-by-step suspended transport vehicle releasing device described in the present invention operates stably, and can give the transport vehicle a certain initial velocity through the cylinder during the releasing process to ensure that the transport vehicle can overcome the static friction force to start from a stationary state, and ensure that each transport vehicle can be released one by one in an orderly manner during the releasing process.

[0026] like Figure 3 As shown, the release mechanism 30 also includes a buffer spring 301. The piston rod of the cylinder 1 is connected to a spherical bearing 9. The buffer spring 301 is sleeved on the outside of the spherical bearing 9 and the piston rod of the cylinder 1.
