Description

Technical Field

[0001] This utility model relates to the field of conveying technology, specifically to a fall prevention device for a high-rise roller conveyor. Background Technology

[0002] Roller conveyors are a common type of continuous conveying equipment that uses rows of rollers as the load-bearing conveying components. They are characterized by large conveying capacity, high conveying efficiency, strong adaptability, and ease of maintenance, and are widely used in industrial production, logistics and warehousing, and other fields.

[0003] In the raw material and finished product warehouses of cigarette manufacturing plants, roller conveyors are commonly used conveying equipment for transporting tobacco leaves or finished cigarettes. Due to warehouse layout, many logistics systems involve connections between the first and second floors. For example, a second-floor roller conveyor might deliver cigarette packs to a vertical lift, which then delivers them to a first-floor roller conveyor. During transport, the cigarette packs on the second-floor roller conveyor are detected by two pairs of photoelectric sensors to stop them on the conveyor. If the photoelectric sensors fail, the cigarette packs will continue to be transported forward. If the vertical lift's loading platform does not reach the second-floor roller conveyor where the packs are to be received, the cigarette packs may fall and damage the equipment or injure personnel. To eliminate this safety hazard, this invention provides a fall prevention device for high-rise roller conveyors. Utility Model Content

[0004] The purpose of this utility model is to provide a fall prevention device for a high-rise roller conveyor, which can automatically block the goods transported by the roller conveyor before the lifting base plate reaches the corresponding floor, thus preventing them from falling.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A fall prevention device for a high-rise roller conveyor includes a roller conveyor and a lifting base plate. The roller conveyor is installed on the floor of each floor, and the lifting base plate is installed on a lifting device so that the lifting base plate can move up and down between each roller conveyor. A toggle mechanism is provided on the front side of the lifting base plate, and an extension side is provided on the rear side of the roller conveyor. A stop bar and a pressing mechanism are provided on the extension side, wherein the stop bar is rotatable.

[0007] The pressing mechanism includes a base box, a pressing head, and a pressing rod. The base box is fixedly installed at the bottom of the roller conveyor. One end of the pressing rod is provided with a pressing head, which is exposed on the outside of the extension side. The other end of the pressing rod is located in the base box and a spring is connected to that end. A rotating lever is also provided on one side of the pressing rod, and a roller is rotatably provided at the end of the rotating lever.

[0008] The end of the baffle bar passes through the extension edge and connects to the cylinder. An arc-shaped groove is provided on the circumferential surface of the cylinder, and the roller extends into the arc-shaped groove.

[0009] Furthermore, the extended edge is provided with a directional hole and a circular hole, the shaft end of the stop bar passes through the circular hole, and the pressing head has a semi-circular main structure and the pressing head passes through the directional hole.

[0010] Furthermore, the inner wall of the bottom box is provided with a rod sleeve, and the pressure rod is a square rod with its end passing through the rod sleeve.

[0011] Furthermore, the pressing mechanism is a roller or a cylindrical rod, and the pressing mechanism can press the pressing head during the lifting and lowering of the base plate.

[0012] Furthermore, a short shaft is provided on the rear end face of the cylinder, the short shaft is rotatably connected to the side wall of the bottom box, and a torsion spring is sleeved on the short shaft. The two ends of the torsion spring are respectively connected to the rear end face of the cylinder and the inner wall of the bottom box.

[0013] Furthermore, side baffles are provided on both sides of the upper surface of the lifting base plate, and pulleys and a rotating shaft are rotatably provided on both sides of the lower surface of the lifting base plate, with guide wheels provided at both ends of the rotating shaft.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This invention features a toggle mechanism on the side of the lifting platform, and a stop bar and pressing mechanism on the rear extension side of the roller conveyor. A cylinder is connected to the shaft end of the stop bar. The toggle mechanism includes a base box, a pressing head, and a pressure rod, with a rotating lever on one side of the pressure rod. A roller at the end of the rotating lever extends into the arc-shaped groove of the cylinder. When the lifting platform moves up and down, the toggle mechanism presses down on the pressing head, causing the stop bar to rotate and allowing goods to pass. When the lifting platform moves away, the stop bar resets under the action of a spring and a torsion spring, blocking the passage of goods again. This mechanical blocking mechanism prevents goods from falling from heights. Compared to photoelectric detection-based fall prevention mechanisms, this method is safer and more reliable, avoiding the risks associated with circuit failures and other malfunctions.

The roller conveyor 2 is installed on the floor 1 of each floor, and the lifting base plate 6 is installed on a lifting device so that the lifting base plate 6 can move up and down between each roller conveyor 2. The lifting base plate 6 is provided with a toggle mechanism 7 on its front side. The toggle mechanism 7 can be a roller or a cylindrical rod. In this embodiment, a roller is preferred. The roller conveyor 2 is provided with an extension side 3 on its rear side. The extension side 3 is provided with a stop bar 4 and a pressing mechanism 5. The stop bar 4 is rotatable. There are two toggle mechanisms 7, two stop bars 4, and two pressing mechanisms 5.

[0027] refer to Figure 4 and Figure 6 As shown, the pressing mechanism 5 includes a base box 54, a pressing head 51, and a pressing rod 53. The base box 54 is fixedly installed at the bottom of the roller conveyor 2. The pressing head 51 is provided at one end of the pressing rod 53 and is exposed on the outside of the extension side 3. The pressing head 51 must be provided in such a way that the actuating mechanism 7 can press the pressing head 51 during the lifting of the lifting base plate 6. The other end of the pressing rod 53 is located in the base box 54 and is connected to a spring 56. A rotating lever 59 is also provided on one side of the pressing rod 53 and a roller 510 is rotatably provided at the end of the rotating lever 59.

[0028] Specifically, the extended edge 3 is provided with a directional hole 32 and a circular hole 31. The shaft end 41 of the stop bar 4 passes through the circular hole 31. The pressing head 51 has a semi-circular main structure and passes through the directional hole 32. The pressing head 51 is designed to be semi-circular so that it can be pressed without obstruction, regardless of whether the actuating mechanism 7 contacts the pressing head 51 from top to bottom or bottom to top. The inner wall of the bottom box 54 is provided with a rod sleeve 55. The pressing rod 53 is a square rod and its end passes through the rod sleeve 55, thereby ensuring the stability of the pressing head 51.

[0029] The shaft end 41 of the stop bar 4 passes through the extension edge 3 and connects to the cylinder 52, for reference. Figure 5 As shown, an arc-shaped groove 58 is provided on the circumferential surface of the cylinder 52. The roller 510 extends into the arc-shaped groove 58. Preferably, the arc-shaped groove 58 is a 1 / 4 arc, so that the roller 510 can drive the cylinder 52 to rotate 90 degrees. Of course, the curvature of the arc-shaped groove 58 can also be designed to be other, as long as it ensures that when the actuating mechanism 7 presses the pressing head 51, the top of the stop bar 4 can be located below the conveying surface of the roller conveyor 2.

[0030] Furthermore, a short shaft 511 is provided on the rear end face of the cylinder 52. The short shaft 511 is rotatably connected to the side wall of the bottom box 54, and a torsion spring 57 is sleeved on the short shaft 511.

Pulleys 9 and rotating shafts 10 are rotatably provided on both sides of the lower surface of the lifting base plate 6. Guide wheels 11 are provided at both ends of the rotating shaft 10. The pulleys 9 are provided to facilitate the connection or bypass of the steel rope of the lifting device. The guide wheels 11 are provided to allow them to slide within the steel frame of the lifting device to help the lifting base plate 6 maintain horizontality.

[0032] The working principle of this utility model is as follows: when the lifting base plate 6 has not reached the roller conveyor 2 of the corresponding floor, the baffle 4 is set vertically to block the goods from continuing to be transported forward. When the lifting base plate 6 reaches the roller conveyor 2 of the corresponding floor, the actuating mechanism 7 presses the pressing head 51, causing the pressure rod 53 to move linearly. During the movement, rotating the roller 510 at the end of the lever 59 will force the cylinder 52 to rotate, thereby causing the baffle 4 to rotate and release the obstruction.

[0033] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims.
