[0002] After the welding wire is processed, it usually needs to be packed into a packaging box for subsequent product transportation. Existing packaging equipment generally uses automated equipment. However, during the packaging process of the automated equipment, when the welding wire products are temporarily out of stock, empty boxes are likely to be generated on the production line. If the empty boxes are to be processed, after the empty boxes are transported along the production line to the subsequent packing station, it is necessary to detect the empty boxes and select them manually or by machine to remove the packaging boxes without welding wire. However, since the packaging boxes need to be transported by a conveyor belt, the existing manual selection method has low efficiency and cannot guarantee accuracy. The existing machine selection mainly identifies empty boxes through vision, which is not suitable for the packaging boxes that have been sealed or closed, and cannot meet the requirements of detecting and removing empty boxes in the welding wire packaging boxes, affecting the packaging efficiency of the welding wire.

[0027] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0028] An empty box detection device, such as Figures 1 to 4As shown in the figure, it includes a conveyor belt 1, a detection mechanism arranged on the conveyor belt 1, and a rejection mechanism arranged on one side of the conveyor belt 1; there are two rollers 2 at the position corresponding to the detection mechanism on the conveyor belt, and there is a receiving gap for accommodating the detection mechanism between the two rollers 2; the detection mechanism includes a detection piece 6 rotatably arranged on the conveyor belt 1, the rotation direction of the detection piece 6 is the same as that of the roller 2, one end of the detection piece 6 extending into the receiving gap is provided with an elastic element 10, and the other end extends out of the receiving gap. At the position corresponding to the lower part of the roller 2 on the conveyor belt 1, there is a positioning plate 11. One end of the elastic element 10 abuts against the positioning plate 11, and the other end abuts against the detection piece 6. Among them, the positioning plate 11 can be fixed on the frame of the conveyor belt 1 or can be installed and fixed on the frame by screws.

[0029] Exemplarily, the conveyor belt 1 can adopt an existing roller conveyor belt, and the two rollers 2 corresponding to the detection mechanism can be rotatably installed on the frame of the conveyor belt 1 through rotating shafts. By setting a receiving gap for accommodating the detection mechanism between the two rollers 2, it is convenient for the detection mechanism to be received and for the packaging box with welding wires to continue to move along the conveyor belt 1.

[0030] Optionally, the detection piece 6 is an L-shaped or V-shaped structural part. Exemplarily, the middle part of the detection piece 6 can be rotatably installed on the frame of the conveyor belt 1 through a rotating shaft. Those skilled in the art can also choose other ways to install the detection piece 6 according to actual needs to achieve the stable rotation of the detection piece 6 on the conveyor belt 1, which will not be elaborated here.

[0031] In the actual application process, the packaging boxes can pass through this detection device one by one. By rotatably installing the middle part of the detection piece 6 on the frame of the conveyor belt 1 and making one end of the detection piece 6 extend out of the receiving gap, when the empty box moves to the detection piece 6 under the action of the conveyor belt 1, due to the light weight of the empty box, it cannot push the detection piece 6 to rotate and compress the elastic element 10. Therefore, the detection piece 6 can play a good role in intercepting the empty box, which is convenient for subsequent use of the rejection mechanism to remove the empty box from the conveyor belt 1. On the contrary, when the packaging box with welding wires moves to the detection piece 6 under the action of the conveyor belt 1, due to the large mass of the packaging box, it can push the detection piece 6 to rotate and compress the elastic element 10, so that after the detection piece 6 is received into the receiving gap, the packaging box can continue to move downward along the conveyor belt 1.

[0032] Optionally, an upper roller 7 is provided at one end of the detection piece 6 extending out of the receiving gap, and the upper roller 7 is rotatably installed on the detection piece 6. Exemplarily, the upper roller 7 can be rotatably installed on the detection piece 6 through a rotating shaft. Those skilled in the art can also choose other ways to install the upper roller 7 according to actual needs to achieve the stable rotation of the upper roller 7 on the detection piece 6.

[0033] In actual use, the rotation direction of the upper roller 7 is the same as that of the roller 2. By arranging the upper roller 7 at the upper end of the detection member 6, when the detection member 6 is received into the accommodation gap, the upper roller 7 can change the sliding friction between the detection member 6 and the packaging box into rolling friction, facilitating the rapid passage of the packaging box through the detection member 6. In addition, the rotated detection member 6 can also play a good role in filling the accommodation gap, which is beneficial for the packaging box with welding wire to smoothly pass through the accommodation gap and continue to be conveyed downward along the conveyor belt 1.

[0034] Optionally, a transmission wheel 8 is provided at the position corresponding to the upper roller 7 and the roller 2 on the detection member 6, and the transmission wheel 8 is rotatably installed on the detection member 6. Exemplarily, the transmission wheel 8 can also be rotatably installed on the detection member 6 through a rotating shaft. By arranging the transmission wheel 8 between the upper roller 7 and the roller 2 and using the transmission wheel 8 to contact the upper roller 7 and the roller 2 respectively, when the detection member 6 is received into the accommodation gap, under the transmission action of the transmission wheel 8, the roller 2 can drive the upper roller 7 to rotate while rotating, which is beneficial for further ensuring that the packaging box can smoothly pass through the detection member 6. In addition, by using the cooperation between the transmission wheel 8 and the roller 2, the rotational limit of the detection member 6 can also be realized, avoiding over-rotation of the detection member 6 under the pressure of the packaging box and preventing the jamming of the packaging box caused by over-rotation of the detection member 6, thus improving the continuity of this detection device when detecting the packaging box.

[0035] Optionally, a lower roller 9 capable of cooperating with the roller 2 is provided at one end of the detection member 6 extending into the accommodation gap, and the lower roller 9 is rotatably installed on the detection member 6. Exemplarily, the lower roller 9 can also be rotatably installed on the detection member 6 through a rotating shaft. By rotatably installing the lower roller 9 at the lower end of the detection member 6, the lower roller 9 can prevent friction between the detection member 6 and the roller 2, thus facilitating the packaging box to push the detection member 6 to rotate.

[0036] Optionally, the elastic element 10 is a compression spring. Exemplarily, the compression spring can be an arc-shaped spring, and clamping blocks capable of cooperating with the compression spring are fixed on both the detection member 6 and the positioning plate 11. By using the clamping blocks to cooperate with both ends of the compression spring, the limitation of both ends of the compression spring can be realized, enabling the compression spring to continuously and stably play a role in limiting and resetting the detection member 6. Those skilled in the art can select a compression spring with appropriate elasticity according to the mass of the empty box so that the empty box cannot push the detection member 6 to rotate, while the packaging box with welding wire can push the detection member 6 to rotate, which will not be elaborated here.

[0037] Optionally, the conveyor belt 1 is provided with a driver 3 for driving the roller 2 to rotate. Exemplarily, the driver 3 can be a driving motor, the fixed end of the driving motor can be fixed to the frame of the conveyor belt 1 by screws, and the output end can be connected to the rotating shaft of the roller 2 by a belt. Those skilled in the art can also select other suitable drivers 3 and their installation methods according to actual needs to achieve stable rotation of the roller 2, which will not be repeated here.

[0038] In actual application, by using the driver 3 to drive the rollers 2 on both sides of the detection mechanism to rotate, it can be ensured that the packaging box with welding wire can have sufficient power to pass through the detection mechanism, further reducing the possibility of the packaging box getting stuck at the detection mechanism.

[0039] Optionally, the rejection mechanism includes a detection device 5 for detecting the stay of the box, and a pushing device 4 for pushing the empty box out of the conveyor belt 1. Exemplarily, both the pushing device 4 and the detection device 5 can be installed on the frame of the conveyor belt 1. Those skilled in the art can also choose other ways to install the pushing device 4 and the detection device 5 according to actual needs, which will not be repeated here. Among them, the pushing device 4 can adopt a high-pressure air blower. Compared with other pushing devices 4, the high-pressure air blower has the advantage of fast corresponding speed. The detection device 5 can adopt existing photoelectric sensors, such as laser sensors or infrared sensors. The use of photoelectric sensors to detect the existence of objects and their stay belongs to the existing technology, so it will not be repeated here.

[0040] In actual application, the detection device 5 and the pushing device 4 can also be connected through an existing controller. When the empty box is intercepted by the detection member 6 and stays on the conveyor belt 1, the detection device 5 can detect that the packaging box stays for 10 seconds, 20 seconds, 30 seconds or other artificially preset time, and then the controller can be used to control the pushing device 4 to work, and the high-pressure blower can be used to blow the empty box out of the conveyor belt 1. The utility model does not involve improvements to the detection device 5, the controller, and the pushing device 4, and the use of a controller to connect the detection device 5 and the pushing device 4 to achieve detection of the packaging box and control of the pushing device 4 are all existing technologies in the field, so they are not repeated here.

[0041] The empty box detection device described in the utility model has the advantages of simple structure, good detection effect, and high applicability. It can be applied to the empty box detection in the welding wire packaging process, has good detection effect on both open empty boxes and sealed empty boxes, and can quickly remove empty boxes, which is beneficial to improving the welding wire packaging efficiency. By setting a receiving gap between the two rollers to accommodate the detection mechanism, it is convenient for the detection mechanism to be stored, and it is convenient for the packaging box with welding wire to move quickly along the conveyor belt, which is beneficial to improving the transmission efficiency of the packaging box with welding wire.

[0042] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
