Description

Technical Field

[0001] This utility model relates to the field of conveyor line technology, and in particular to a product weight detection device. Background Technology

[0002] After the products are packed, they need to be transported to a designated location for retrieval or stacking. However, before stacking, it is necessary to check whether the box contains the specified number of products. To avoid damaging the packaging, this is generally done by weighing. If the weight of the box is within a preset range, it means that the number of products inside the box is correct.

[0003] Currently, the common method is to add a weighing device to the product conveyor line to obtain the weight of the boxes while they are being transported. However, existing weighing devices generally only have a weighing function. When the weight of a box is found to be unqualified, it is still necessary to manually remove the unqualified box. This results in high labor costs, and if the box is not removed in time, it will cause the conveyor line to stop, which will greatly affect production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a product weight detection device that can automatically reject unqualified products, resulting in low labor costs and high production efficiency.

[0008] A weighing mechanism is disposed below the conveying mechanism, and the weighing mechanism is configured to detect the weight of the product;

[0009] The rejection mechanism includes a second driving member and a push plate. The push plate is disposed above the roller. The second driving member is configured to drive the push plate to move along a second direction perpendicular to the first direction, thereby pushing the product away from the roller.

[0010] The controller is electrically connected to the first drive unit, the weighing mechanism, and the second drive unit, respectively.

[0011] Furthermore, the rejection mechanism also includes a support box and a first connecting rod.

The roller is disposed in the roller groove and rotatably connected to the support base. A slot is formed on the bottom wall of the roller groove, and the slot extends along a second direction. The first connecting rod is at least partially disposed in the slot and can move along the slot.

[0028] The following detailed, non-limiting description of the utility model's technical solution, in conjunction with preferred embodiments and accompanying drawings, is provided. In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. Furthermore, the terms "first" and "second" 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, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0029] like Figures 1 to 4 As shown in the figure, an embodiment of this utility model provides a product weight detection device, including a controller 5 and a conveying mechanism 1, a weighing mechanism 2, and a rejection mechanism 3 electrically connected to the controller 5. The conveying mechanism 1 is a roller conveyor belt that can transport products 6 placed on it. During the transport of products 6, the weighing mechanism 2 detects the weight of the product 6 and sends the data to the controller 5, which then determines whether the weight of the product 6 is within a preset range. If the weight of the product 6 is within the preset range, it is qualified and transported to the next workstation by the conveying mechanism 1. Conversely, if the weight is not within the preset range, the rejection mechanism 3 pushes the product 6 away from the conveying mechanism 1, thereby achieving automated rejection of unqualified products 6 and preventing unqualified products 6 from accumulating on the conveying mechanism 1, causing production line stagnation and affecting production efficiency.

[0030] Specifically, the conveying mechanism 1 includes multiple evenly arranged rollers 10 and a first driving member 16. The first driving member 16 drives the rollers 10 to rotate, thereby driving the product 6 to move along the first direction X. The conveying mechanism 1 also includes a support base 12, on which a roller groove 120 is provided. The rollers 10 are disposed within the roller groove 120 and rotatably connected to the support base 12. The first driving member 16 is disposed within a protective shell 125 on the side of the support base 12 and is drively connected to the rollers 10. This design not only prevents dust and debris from affecting the rotation of the rollers 10, but also improves the overall appearance.

[0031] In addition, a photoelectric sensor 15 is provided on the conveying mechanism 1, and the photoelectric sensor 15 is located in the middle of the conveying mechanism 1 to detect whether a product 6 is transported to the conveying mechanism 1.

[0032] The weighing mechanism 2 is an existing weighing structure, that is, it has a pressure sensor 20 and a processor 21 electrically connected to the pressure sensor 20. When the weight on the weighing mechanism 2 changes, that is, when the product 6 is transported to the conveying mechanism 1, the electrical signal output by the pressure sensor 20 changes, and the processor 21 calculates the weight of the product 6 based on the change in the electrical signal.

[0033] The rejection mechanism 3 includes a second drive member 30 and a push plate 31. The push plate 31 is disposed above the roller 10. The second drive member 30 drives the push plate 31 to move along a second direction Y perpendicular to the first direction X, thereby pushing the product 6 away from the roller 10. The controller 5 is electrically connected to the first drive member 16, the weighing mechanism 2, and the second drive member 30 to achieve precise control of the device's operation.

[0034] Furthermore, the rejection mechanism 3 also includes a support box 32 and a first connecting rod 33. The support base 12, the support box 32, and the weighing mechanism 2 are arranged sequentially in the vertical direction. The aforementioned second driving member 30 is fixed inside the support box 32 by screws. One end of the first connecting rod 33 is connected to the output end of the second driving member 30, and the other end passes through the gap 11 between adjacent rollers 10 and is fixedly connected to the push plate 31. The second driving member 30 is arranged along the second direction Y and can drive the first connecting rod 33 to move along the second direction Y, thereby driving the push plate 31 to move along the second direction Y, and finally pushing the product 6 to move along the second direction Y.

[0035] Preferably, in this embodiment, the second driving component 30 is an electric push rod with a sealed, dustproof, and waterproof design, which can withstand dust and oil stains on the conveying mechanism site, extend the equipment life, and has a fast response speed.

[0036] Preferably, a groove 122 is formed on the bottom wall 121 of the roller groove 120. The groove 122 extends along the second direction Y. The first connecting rod 33 is at least partially disposed within the groove 122 and can move along the groove 122. That is, the first connecting rod 33 passes through the groove 122 and the gap 11 in sequence and is fixed to the push plate 31. In this embodiment, the width of the groove 122 is slightly larger than the width of the portion of the first connecting rod 33 disposed within the groove 122, so that it can play a guiding role during the movement of the first connecting rod 33, making the movement of the first connecting rod 33 more stable.

[0037] Optionally, the first connecting rod 33 is U-shaped, with its opening facing the roller 10. Two slots 122 are arranged in parallel to allow the two ends of the U-shaped opening of the first connecting rod 33 to pass through, thereby further improving the stability of the first connecting rod 33 during movement.

[0038] Furthermore, to reduce the horizontal installation space and footprint of the device, the rejection mechanism 3 also includes a second connecting rod 34. One end of the second connecting rod 34 is fixed to the first connecting rod 33, and the other end is fixed to the output end of the second driving member 30. The second connecting rod 34 is L-shaped, and its vertical projection at least partially overlaps with the vertical projection of the second driving member 30.

[0039] Furthermore, the push plate 31 has an initial position. Due to the thickness of the first connecting rod 33, a gap 123 exists between the push plate 31 and the support base 12 when in the initial position. To prevent the product 6 from getting stuck in the gap 123 during transportation, which would prevent the push plate 31 from pushing the product 6, the conveying mechanism 1 also includes a baffle 13, which is disposed above the roller 10 to guide the product 6. The baffle 13 is inclined from the first side 124 of the support base 12 toward the push plate 31, so that the product 6 can move along the baffle 13 to the right side of the push plate 31 when it moves, thus preventing the product 6 from getting stuck in the gap 123.

[0040] Furthermore, when the push plate 31 is in the initial position, the baffle 13 is in contact with the push plate 31, that is, there is no gap between the baffle 13 and the push plate 31, so as to prevent debris from passing through the gap between the baffle 13 and the push plate 31 and affecting the movement of the push plate 31, thus causing damage to the device.

[0041] In this embodiment, baffles 13 are provided at both ends of the push plate 31 to make the device applicable to more usage scenarios, so that it can be used regardless of which direction the product 6 is conveyed by the conveying mechanism 1.

[0042] In addition, the product weight detection device also includes a control cabinet 4 and at least one third connecting rod 40. One end of the third connecting rod 40 is fixedly connected to the weighing mechanism 2, and the other end is fixedly connected to the control cabinet 4. The third connecting rod 40 is designed as a hollow structure to facilitate wiring. The hollow third connecting rod 40 serves two purposes: it can fix the control cabinet 4, and it also facilitates wiring, avoiding exposed wires and improving the safety and aesthetics of the device.

[0043] Furthermore, the control cabinet 4 is equipped with a touch screen display 41 that is electrically connected to the controller 5 and the weighing mechanism 2. After the weighing mechanism 2 obtains the weight of the product 6, it can be displayed on the touch screen display 41. The user can also input the weight range of the product 6 at the touch screen display 41.

[0044] Finally, in this embodiment, the product weight detection device also includes a recovery platform 7, which is arranged opposite to the push plate 31 and adjacent to the conveying mechanism 1. In the horizontal direction, the platform 70 of the recovery platform 7 is not higher than the carrying surface 14 of the conveying mechanism 1 to receive the pushed-away product 6. Furthermore, casters are provided under the recovery platform 7 for rapid transfer.

[0045] Understandably, another conveyor line could be set up at the recycling station 7 to transport the defective products 6 to the processing station, which would be more efficient, but the corresponding cost would also be higher.

[0046] The working process of the product weight detection device provided by this utility model is as follows:

[0047] First, the user inputs the weight range of product 6 under acceptable conditions at the touch display 41. Then, product 6 is conveyed from the first direction X onto the conveyor mechanism 1. The first drive unit 16 drives the roller 10 to rotate, thereby driving product 6 to continue moving along the first direction X. When product 6 reaches the middle position of the conveyor mechanism 1, the photoelectric sensor 15 detects product 6, and the controller 5 controls the first drive unit 16 to stop working. At this time, the weighing mechanism 2 detects the weight of product 6 and sends a signal to the controller 5 and the touch display 41. The touch display 41 displays the weight of product 6, and the controller 5 determines whether the weight is within the range. If the weight of product 6 is within the preset range, it is acceptable, and the controller 5 controls the first drive unit 16 to start, conveying product 6 to the next station. Otherwise, it controls the second drive unit 30 to start, driving the pusher plate 31 to move along the second direction Y, thereby pushing product 6 away from the conveyor mechanism 1 and moving product 6 to the recycling table 7. This achieves automated rejection of unacceptable product 6, preventing unacceptable product 6 from accumulating on the conveyor mechanism 1, causing production line stagnation, and affecting production efficiency.

[0048] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
