Abstract
Description
Technical Field
[0001] This utility model relates to the field of production logistics technology, and in particular to a roller conveyor step. Background Technology
[0002] When finished cigarettes leave the warehouse, roller conveyors are often used to transport entire pallets of cigarettes or pallet groups. At the same time, maintenance or operation personnel often need to cross the roller conveyors to perform maintenance or operation work. The roller conveyors are generally about 80 centimeters above the ground and 1-2 meters wide. In this case, the common approach to crossing the roller conveyor is to build a fixed crossing platform (bridge) directly above the roller conveyor. However, when building such a bridge, it is necessary to avoid the pallets of cigarettes or pallet groups (which are close to 2 meters high) on the roller conveyor below. In addition, the height of the bridge needs to be set at no less than 2.5 meters. Including the steps on both sides, it is obvious that building such a crossing bridge is not easy to implement and has extremely low passage efficiency, which is time-consuming and labor-intensive.
[0003] Based on this, the roller conveyor steps of this application were designed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a roller conveyor step, which is used for conveying cigarette pallets or pallet groups by roller conveyor when finished cigarettes are shipped out of the cigarette factory. It has the advantages of high technical reliability, high conveying efficiency and low cigarette damage rate.
[0005] The technical problem to be solved by this utility model is achieved through the following technical solution:
[0006] A roller conveyor step includes multiple step bodies, each step body being disposed between two adjacent electric rollers of the roller conveyor. The upper edge of each step body is lower than the height of the circular surface of the electric roller, and the bottom of each step body is fixed to the roller conveyor base.
[0007] Preferably, in the above technical solution, the step body is an arc-shaped structure, the width of its upper edge is adapted to the gap width between two adjacent electric rollers, and does not interfere with the operation of the electric rollers.
[0008] Preferably, in the above technical solution, the upper edge of the step body gradually increases in height along the running direction of the roller conveyor to form an inclined plane, and the angle between the inclined plane and the horizontal plane is less than 30°.
[0009] Preferably, in the above technical solution, the height difference between the upper edge of the step body and the circular surface height of the electric roller is less than 2 mm.
[0010] Preferably, in the above technical solution, the gap between two adjacent electric rollers is 10 cm, and the diameter of the circular surface of the electric roller is less than 10 cm.
[0011] Preferably, in the above technical solution, the width of the roller conveyor is 1-2 meters and the height is 80 centimeters above the ground.
[0012] The above-mentioned technical solution of this utility model has the following beneficial effects:
[0013] (1) It improved the efficiency of maintenance operators passing through the roller conveyor;
[0014] (2) It reduces the labor intensity of operation and maintenance personnel. Attached Figure Description
[0015] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments of the present invention and, together with their description, serve to explain the principles of the present invention.
[0016] Figure 1 This is a schematic diagram of the roller conveyor steps.
[0017] Figure 2 This is another schematic diagram of the roller conveyor steps.
[0018] Wherein: 1-electric roller, 2-step body, 3-roller conveyor base. Detailed Implementation
[0019] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps set forth in these embodiments do not limit the scope of the present invention.
[0020] like Figure 1 As shown, this application relates to a roller conveyor tread, which is part of a finished cigarette warehousing system. This system includes a high-bay warehouse, stacker crane, chain conveyor, roller conveyor, robotic arm, sorting machine, etc.
[0021] When the finished goods outbound system is running normally, the warehouse management system (WMS) sends outbound tasks to the warehouse control system (WCS). The WCS schedules the stacker crane to take out the palletized cigarettes and send them to the corresponding chain conveyor. The chain conveyor then transports the cigarette pallet to the roller conveyor, which then transports it to the next outbound stage.
[0022] Finished product shipments utilize numerous roller conveyors as transport equipment. These conveyors are arranged in a multi-layered planar layout and contain robotic arms and other devices. Maintenance or operation personnel frequently need to cross these roller conveyors for repairs or operations. The roller conveyors are typically about 80 centimeters above the ground and 1-2 meters wide. In this situation, a common approach to crossing the roller conveyors is to build a fixed crossing platform (bridge) directly above them. However, when building such a bridge, it is necessary to avoid palletized cigarettes or pallet assemblies (nearly 2 meters high) on the roller conveyors below. Considering the height of the roller conveyors themselves, the bridge height needs to be set at no less than 2.5 meters. Including the steps on both sides, it is clear that building such a crossing bridge is not easy to implement and has extremely low traffic efficiency, being time-consuming and labor-intensive.
[0023] Based on this, the present application proposes a roller conveyor step, which includes multiple step bodies 2. The step bodies 2 are disposed between two adjacent electric rollers 1 of the roller conveyor. The upper edge of the step body 2 is lower than the height of the circular surface of the electric roller. The bottom of the step body 2 is fixed on the roller conveyor base 3.
[0024] Because the roller conveyor is approximately 80 cm high, the electric rollers are unstable and prone to rotation when stationary, making direct passage impossible. However, a 10 cm gap is reserved between adjacent electric rollers 1. The diameter of the electric roller 1's circular surface is less than 10 cm. A special step 2 with an arched structure is installed in each gap. The bottom of the step 2 is fixed to the roller conveyor base 3. The width of the upper edge of the step 2 is close to the gap width of the electric roller 1, but it should not affect the operation of the electric roller 1. The height of the upper edge is close to the circular surface height of the electric roller 1, slightly lower by about 2 mm, and along the direction of roller conveyor operation (indicated by the arrow), the height of the upper edge is... The steps gradually rise (the upper edge of step 2 is a small-angle slope), and its shape is similar to an inverted trapezoid. When the roller conveyor is stopped, when the operator or maintenance personnel walk across the roller conveyor and step directly onto the electric roller 1, due to the ergonomic characteristics of the human foot and the softness of the foot, the foot can make good use of step 2 as the main support, while electric roller 1 is used for auxiliary support. At the same time, since the length of an adult's foot is generally at least 20 centimeters (the total width of one electric roller 1 and one step 2 is nearly 20 centimeters), this ensures that each foot can contact at least one step, and the personnel will not experience instability. In this way, they can pass through the roller conveyor very smoothly.
[0025] Meanwhile, since the height of the upper edge of step 2 is slightly lower than the height of the circular surface of electric roller 1, and it gradually rises along the running direction of the roller conveyor (the upper edge of the step is a small-angle slope), when there are slightly protruding wooden parts or nails at the bottom of the cigarette tray or tray group (wooden tray), they will not be blocked by the upper edge of step 2, but will pass smoothly along the running direction of electric roller 1 of the roller conveyor, ensuring that the roller conveyor with step device installed can smoothly pass through the cigarette tray or tray group.
[0026] Therefore, by utilizing this roller conveyor stepping device, the problem of ensuring the safe and efficient passage of maintenance operators through the roller conveyor has been perfectly solved.
[0027] This roller conveyor step utilizes the existing roller conveyor layout, combined with the roller conveyor's operating direction, and also takes advantage of ergonomic features. It allows for a smooth and safe crossing of the roller conveyor when it is stopped, saving time and effort, and is highly efficient and fast.
[0028] Although the present invention has been disclosed above with reference to embodiments, it is not intended to limit the present invention. Any person skilled in the art can make various different choices and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention is defined by the claims and their equivalents.
