Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of logistics conveying chute, specifically is a kind of converging spiral chute. BACKGROUND

[0002] In the logistics sorting industry, when the goods on two parallel conveyors need to be converged to a position, generally, the goods on the two conveyors are converged together by manual carrying, but this method consumes a lot of manpower and is a big test for the strength of the carrier. Therefore, people think of using two guide slots to guide the goods on the two conveyors, so that the goods on the two conveyors converge to a position. At this time, the goods transported by the two conveyors can be directly transported to a position without assigning a person to carry the goods on the two conveyors, saving manpower.

[0003] Among them, there are many types of chutes, such as spiral chutes, flat inclined plate chutes and other different chutes produced on demand.

[0004] The existing converging spiral chute is made of smooth spiral groove plate, and the package rotates around the center and slides down in a spiral manner, which is transported. However, the package rotates around the center and slides down during the sliding process, and the rotation and sliding will generate a certain centrifugal force. The heavier the package, the faster the sliding speed and the greater the centrifugal force. It is difficult to ensure the stability of the rotating and sliding of the package by relying on the enclosure on both sides of the groove body. Under the action of centrifugal force, it is easy to cause the package to fly out. When the package rotates and slides, the torque direction of the inclined surface sliding can only be single, and it is not spiral. The package can rotate and slide, completely rely on the collision of the side wall to limit, forcibly change the sliding torque direction of the package, so that the package rotates and slides in the collision, and the package enters a curved position and collides once, changes the sliding direction. This method is likely to cause damage to the package, thereby affecting the safety of transportation and the quality of package transportation.

[0005] Therefore, in view of the above problems, the existing structure is improved, and a converging spiral chute is proposed. CONTENT OF THE UTILITY MODEL

[0019] The technical scheme in the embodiments of the utility model will be apparently and completely described below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor fall within the scope of protection of the utility model.

[0020] As Figures 1-3 Shown, a kind of confluence spiral chute, including center column 1, center column 1 is divided into two symmetrical, the surface of center column 1 is all fixedly covered with spiral groove 2, the outer surface of spiral groove 2 upper side is all fixedly installed with protrusion 3, protrusion 3 is set as the arc plate that protrudes to one side of center column 1, the inner surface wall of spiral groove 2 is all provided with recess 4, recess 4 is evenly distributed rotationally connected with soft roller 5, one side of soft roller 5 protruding recess 4 is located in the interior of spiral groove 2.

[0021] By adopting the above technical scheme, protrusion 3 will the arc-shaped inner recess limit of spiral groove 2 upper end opening, so as to avoid, in the quality of too large wrapping fast rotation downslide, produce too large centrifugal force and make wrapping fly out and separate from spiral groove 2 condition;

[0022] The centrifugal force also makes the package wrapped around the side wall of the spiral groove 2 preferentially contact the soft roller 5 when sliding in a spiral curve, and the soft roller 5 avoids damage to the package caused by direct collision with the side wall by utilizing its flexible roller body.

[0023] The soft roller 5 also rotates due to friction, thereby being able to more quickly guide the package to turn and slide downward.

[0024] Further, the bottom end of the spiral groove 2 is fixedly connected with a same converging groove 6, and the converging groove 6 is arranged in a "Y" shape.

[0025] By adopting the above technical solution, the converging groove 6 can simultaneously receive the packages conveyed by the two spiral grooves 2.

[0026] Further, the inner surface of the converging groove 6 is provided with a sunken groove 7 on the left and right sides of the bifurcated and merged part of the "Y" shape.

[0027] The inner surface of the sunken groove 7 is provided with a torsion spring 10 fixedly installed on the outer side of the shaft rod 8 on the upper and lower sides.

[0028] The opposite ends of the torsion spring 10 are fixedly connected with the movable plate 9, and the opposite ends of the movable plate 9 are protrudingly provided with a buffer cotton plate 11 fixedly installed in the sunken groove 7.

[0029] By adopting the above technical solution, when the package moves downward to the converging groove 6, it will collide with the buffer cotton plate 11. The buffer cotton plate 11 will be impacted and will drive the shaft rod 8 to rotate through the movable plate 9, thereby pulling the torsion spring 10 to rotate. The rotation of the torsion spring 10 will generate a certain reset elastic force, which will weaken the impact generated by the downward sliding of the package. When the packages converge, the sliding speed of the package can be greatly reduced, thereby avoiding the situation that the packages directly converge and collide at high speed to cause damage.

[0030] Working principle: when using the spiral chute, first, the packages on the two sides of the logistics platform can be put into the left and right spiral grooves 2 respectively. When the packages slide down along the spiral groove 2, they will rotate around the center column 1 due to the spiral shape, that is, the packages will generate a certain centrifugal force. The convex 3 will limit the opening of the upper end of the spiral groove 2 in an arc shape, so as to avoid the situation that the packages fly out of the spiral groove 2 due to the excessive centrifugal force generated by the rapid rotation of the packages with excessive weight. The centrifugal force will also make the packages contact the soft roller 5 first when sliding down along the spiral curved wall. The soft roller 5 uses its flexible roller body to avoid damage to the packages caused by direct collision with the wall. At the same time, the soft roller 5 will also rotate due to friction, so as to guide the packages to turn and slide down faster. When the packages slide to the bottom of the spiral groove 2, they will enter the converging groove 6. When the packages slide down to the converging groove 6, they will collide with the buffer cotton board 11. The buffer cotton board 11 will rotate the shaft 8 through the movable plate 9 when it is hit, and then pull the torsion spring 10 to rotate. The rotation of the torsion spring 10 will generate a certain reset elastic force, which will weaken the impact generated by the sliding down of the packages. When the packages converge, the sliding speed of the packages can be greatly reduced to avoid the situation that the packages are directly converged and collide at high speed, which will damage the packages. This is the working principle of the spiral chute.
