Description

Technical Field

[0001] This utility model belongs to the field of I-beam wheel sorting technology, and relates to a water tank I-beam wheel sorting system. Background Technology

[0002] The monofilament water tank I-beams produced on the robotic production line have different specifications. After production, the I-beams are assembled onto pallets that match their specifications. Workers then sort the I-beams on the pallets to the corresponding areas. Due to the limited size of the pallets, the process of repeatedly moving and sorting the I-beams is time-consuming and labor-intensive. Furthermore, the process may cause unnecessary dangers due to worker errors such as bumps and knocks. Therefore, a water tank I-beam sorting system is urgently needed to solve the above technical problems. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a water tank I-beam wheel sorting system. This system can solve the technical problems in the prior art, where the limited pallet size leads to the time-consuming and labor-intensive process of repeatedly moving water tanks on I-beam wheels for sorting, and the possibility of unnecessary dangers caused by worker errors and collisions during the handling process.

[0004] To alleviate the above-mentioned technical problems, this utility model is implemented using the following technical solution:

[0005] In a first aspect, the present invention provides a water tank I-beam wheel sorting system, comprising:

[0006] Pallets are used to support water tanks of different models on I-beam wheels.

[0007] At least one pair of photoelectric sensors are used to receive light signals collected when the pallet enters the sorting mechanism, and convert the light signals into electrical signals and transmit them to the PLC controller.

[0008] The PLC controller is used to receive the electrical signals from the photoelectric sensor and transmit them to the robotic arm;

[0009] The sorting mechanism receives signals from the PLC controller and acts on the water tank rollers in the tray to complete the sorting.

[0010] Furthermore, the distance between each pair of photoelectric sensors is less than or equal to the width of the tray.

[0011] Furthermore, the sorting mechanism includes a robotic arm that is signal-connected to the PLC controller. The robotic arm includes grippers that can adjust the gripping range, and the gripping range of the grippers corresponds one-to-one with the model of the I-beam wheel of the water tank.

[0012] Furthermore, the sorting mechanism also includes:

[0013] A three-axis motion module is used to slide with the robotic arm to achieve displacement in the horizontal and vertical directions.

[0014] Furthermore, the sorting mechanism also includes:

[0015] A gantry frame is used to connect to and support the three-axis motion module.

[0016] Furthermore, the photoelectric sensor is arranged on the gantry frame at the same horizontal plane as the tray.

[0017] Furthermore, the sorting mechanism also includes:

[0018] In the sorting area, the photoelectric sensor is used to receive the light signal collected when the pallet enters the sorting mechanism, and the sorting area is divided according to the specifications of the pallet.

[0019] Furthermore, it also includes:

[0020] A buffer unit is used to store the water tank I-beams that are sorted by the robotic arm. The buffer unit includes a limiting part for restricting the displacement of the water tank I-beams.

[0021] Compared with the prior art, the beneficial effects achieved by this utility model are as follows:

[0022] The photoelectric sensor collects the light signal when the pallet enters the sorting area. The photoelectric sensor then converts the light signal into an electrical signal and transmits it to the PLC controller. The PLC controller controls the robotic arm to work according to the signal transmitted by the photoelectric sensor to complete the sorting. This solves the technical problems in the prior art, where the limited size of the pallet leads to the time-consuming and labor-intensive process of workers repeatedly moving water tanks and using I-beams for sorting. Furthermore, the process may also cause unnecessary dangers due to worker errors such as bumps and knocks. By replacing manual labor with machines to complete the sorting, sorting efficiency is improved, and the risks that workers may encounter during the sorting process are avoided.

[0023] Since the robotic arm includes adjustable grippers, and the gripping range of the grippers corresponds one-to-one with the model of the water tank I-beam, sorting can be completed for different models of water tank I-beams simply by adjusting the different grippers on the robotic arm, further improving sorting efficiency.

[0027] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0028] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art will understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1:

[0030] like Figure 1 and Figure 2 As shown, this embodiment provides a water tank I-beam wheel sorting system, including:

[0031] The tray 1 is used to support water tank I-beam wheels 2 of different models. In this embodiment, the model of the water tank I-beam wheels 2 can be 220, 236 and 255, which means that the diameter of the water tank I-beam wheels 2 is 220 mm, 236 mm and 255 mm.

[0032] At least one pair of photoelectric sensors are used to receive light signals collected when the pallet 1 enters the corresponding sorting mechanism, and convert the light signals into electrical signals and transmit them to the PLC controller 3. The sorting mechanism includes a sorting area, and the photoelectric sensors are used to receive light signals collected when the pallet enters the sorting area. The sorting area is divided according to the specifications of the pallet.

[0033] The distance between each pair of photoelectric sensors is less than or equal to the width of the tray 1, which enables better monitoring of whether the tray 1 has entered the corresponding sorting area.

[0034] The PLC controller 3 is used to receive the electrical signals from the photoelectric sensor and transmit them to the robotic arm 4.

[0035] The sorting mechanism includes a robotic arm 4 connected to a PLC controller 3 for receiving signals from the PLC controller 3 and acting on the water tank rollers 2 in the pallet 1 to complete the sorting.

[0036] The robotic arm 4 includes grippers 41 with adjustable gripping ranges. The gripping range of the grippers 41 corresponds one-to-one with the model of the water tank I-beams 2. The gripping range refers to the distance between the grippers 41 on the same horizontal line. The correspondence between the gripping range of the grippers 41 and the model of the I-beams means that the distance between the grippers 41 corresponds one-to-one with the diameter of the I-beams. Therefore, by adjusting the gripping range of the grippers 41 on the robotic arm 4, sorting can be completed for different models of water tank I-beams 2, further improving sorting efficiency. Preferably, the adjustment of the specifications of the grippers 41 can be achieved by a PLC controller 3. The PLC controller 3 can identify different models of water tank I-beams 2 based on the electrical signals transmitted by the photoelectric sensor, and then adjust the rotation of the grippers 41 of different specifications on the robotic arm 4 according to the different signals of the water tank I-beams 2, which greatly improves the sorting efficiency. The specific algorithm logic is existing technology and will not be described in detail here.

[0037] The sorting mechanism also includes a three-axis motion module 5, which is slidably connected to the robotic arm 4 to achieve displacement in the horizontal and vertical directions. The three-axis motion module 5 is a conventional technology and will not be described in detail here.

[0038] The sorting mechanism also includes a gantry frame 6, which is used to connect with the three-axis motion module 5 and support the three-axis motion module 5. The gantry frame 6 is a conventional technology and will not be described in detail here. The photoelectric sensor is arranged on the gantry frame 6 at the same horizontal plane as the pallet 1 to monitor the pallet 1.

[0039] A buffer unit is used to store the water tank I-beam wheels 2 that are sorted by the robotic arm 4. The specific buffer unit can be set according to the actual scenario. The buffer unit includes a limiting part for limiting the displacement of the water tank I-beam wheels 2. The limiting part can be similar to the limiting structure set on the tray 1 to prevent the water tank I-beam wheels 2 from being displaced. Example 2:

[0040] This embodiment further defines some of the components disclosed in Embodiment 1. Otherwise, it is the same as Embodiment 1 and will not be described again.

[0041] The robotic arm 4 is model ZDH-FJZ-001, which is a common robotic arm 4 on the market. The robotic arm 4 is used to receive signals from the PLC controller 3 and act on the water tank I-beam wheel 2 in the tray 1 to complete the control logic in sorting. This is conventional existing technology and will not be described in detail here.

[0042] The PLC controller 3 is model 6ES7 521-1BL00-0AB0, which is a common PLC controller 3 on the market. The signal transmission logic of the PLC controller 3 receiving the electrical signal from the photoelectric sensor and transmitting it to the robotic arm 4 is conventional existing technology and will not be described in detail here.

[0043] The photoelectric sensor is model E3Z-T81A2M, which is a common photoelectric sensor on the market. Its function of collecting the light signal when the tray 1 enters the corresponding sorting area and converting it into an electrical signal to transmit to the signal transmission logic in the PLC controller 3 is conventional existing technology and will not be described in detail here.

[0044] Working principle: When the tray 1 enters the sorting area, the light signal is collected by the photoelectric sensor. The photoelectric sensor then converts the light signal into an electrical signal and transmits it to the PLC controller 3. The PLC controller 3 controls the robotic arm 4 to work according to the signal transmitted by the photoelectric sensor to complete the sorting. This solves the technical problems in the prior art where the limited size of the tray 1 leads to the time-consuming and labor-intensive process of workers repeatedly moving the water tank I-beams 2 for sorting, and the unnecessary danger caused by workers' mistakes and bumps during the handling process. By replacing manual labor with machines to complete the sorting, sorting efficiency is improved and the risks that workers may encounter during the sorting process are avoided.

[0045] Since the robotic arm 4 includes a rotatable and adjustable gripper 41, and the gripping range of the gripper 41 corresponds one-to-one with the model of the water tank I-beam 2, it is only necessary to adjust the different grippers 41 on the robotic arm 4 to complete the sorting for different models of water tank I-beam 2, which further improves the sorting efficiency.

[0046] The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention.
