Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 This embodiment provides a technical solution: an automatic weighing and barcode reading device for express delivery, including a platform 1, which provides support for the setting of the weighing and barcode reading components. A weighing plate 2 is provided in the middle of the upper surface of the platform 1 to provide space for weighing the express delivery. A barcode reading camera 3 is provided on the lower surface of the mounting plate at the upper end of the platform 1. The barcode reading camera 3 collects the barcode image information on the upper surface of the express delivery and converts it into a digital signal. By analyzing the digital signal, the barcode of the express delivery can be read. The device also includes a conveying mechanism 5.

[0022] Conveying mechanism 5 includes a loading plate 51, a unloading plate 52, a chute 53, and a sliding plate 54. The loading plate 51 is located at the right end of the upper surface of platform 1, and the unloading plate 52 is located at the left end of the upper surface of platform 1. The upper surfaces of the loading plate 51, the unloading plate 52, and the weighing plate 2 are all provided with chute 53. The sliding plate 54, which moves in a circular motion, is slidably connected inside the chute 53. The upper surface of the sliding plate 54 as a whole gradually slopes downward from the front and rear sides towards the middle. When the express delivery is placed on the upper surface of the loading plate 51, it moves counterclockwise through the sliding plate 54. The package is continuously lifted upwards and moved to the left in a circular motion, and then placed on the surface of the loading plate 51 again. The above operation is repeated to automatically move the package from right to left. During the movement, the tilt of the upper surface of the sliding plate 54 is used to make the package move towards the longitudinal center of the weighing plate 2 under the action of gravity during the lifting process, so that the delivery trajectory of the package is centered and more accurate. After the code is read and the weight is weighed, as the package continues to move to the left, the package falls down from the slope of the unloading plate 52 into the external transfer frame.

[0023] The front surface of platform 1 is equipped with a PLC controller 4. The input terminal of the PLC controller 4 is electrically connected to an external power supply. The barcode reader 3 is bidirectionally electrically connected to the PLC controller 4 to control the start and stop of the overall device. When the PLC controller 4 receives the weighing data, the PLC controller 4 controls the barcode reader 3 to work. At this time, the express delivery is located on the surface of the weighing plate 2. The barcode reader 3 continuously collects the barcode information on the surface of the express delivery. The barcode information on the surface of the express delivery is accurately collected when the express delivery is placed on the surface of the weighing plate 2 and is not lifted, so as to avoid the influence of the movement of the express delivery on the barcode reading.

[0024] The conveying mechanism 5 also includes a sliding plate 55, a rotating plate 56, and a turntable 57. The turntable 57 is rotatably connected to the front and rear inner walls of the platform 1 via a rotating shaft 1. The eccentric ends of the two turntables 57 in the longitudinal position are rotatably connected to the rotating plate 56 via a rotating shaft 2. The upper ends of the rotating plates 56 pass through the clearance holes on the upper surface of the platform 1 and are fixedly connected to the lower surface of the sliding plate 55. The slide plates 54 are all set on the upper surface of the sliding plate 55. When the right turntable 57 rotates, the right turntable 57 drives the rotating plate 56 to rotate. With the connection of the sliding plate 55, the left and right turntables 57 rotate synchronously. The sliding plate 55 drives the slide plates 54 to perform counterclockwise circular motion. During the rotation, the sliding plate 55 remains horizontal. When the rotating shaft 2 of the rotating plate 56 corresponds to the lateral position of the rotating shaft 2 of the turntable 57, the upper surface of the slide plate 54 and the upper surface of the feeding plate 51 are in the same plane, ensuring that the slide plate 54 can accurately lift the express delivery upwards during the rotation.

[0025] The conveying mechanism 5 also includes a gear 58 and a motor 59. The motor 59 is located inside the platform 1. The output shaft of the motor 59 is equipped with a gear 58. The outer arc surface of the turntable 57 on the right side is equipped with an external gear ring. The external gear rings are meshed with the adjacent gears 58 respectively. The input end of the motor 59 is electrically connected to the output end of the PLC controller 4. The output shaft of the motor 59 is equipped with a drive shaft. The drive shaft is rotatably connected to the inner wall of the platform 1. There are two gears 58, which are respectively located at the front and rear ends of the drive shaft. The gears 58 are meshed with the two external gear rings on the right side respectively. When the motor 59 is started, the output shaft of the motor 59 drives the gear 58 to rotate. Through the meshing connection between the gear 58 and the external gear ring, the external gear ring drives the turntable 57 on the right side to rotate. There are elastic rubber pads between the rotating plate 56 and the inner wall of the clearance hole of the platform 1. Through the deformation of the elastic rubber pads, the clearance hole of the platform 1 is sealed during the movement of the rotating plate 56 to prevent external dust from entering the interior of the platform 1 and to ensure the normal operation of the transmission components such as the gear 58 and the turntable 57.

[0026] Rubber pads 6 are provided at both ends of the slide plate 54. The rubber pads 6 are respectively attached to the inner wall of the slide groove 53. During the circular motion of the slide plate 54, the deformation of the rubber pads 6 seals the gap between the slide plate 54 and the slide groove 53, preventing debris from entering the interior of the slide groove 53 and causing the slide plate 54 to be obstructed.

[0027] A baffle 7 is symmetrically provided between the upper surfaces of the feeding plate 51 and the unloading plate 52 to prevent the express delivery from leaving the surfaces of the feeding plate 51 and the unloading plate 52 during the transportation process.

[0028] Weighing sensors 8 are respectively installed between the lower surface of the weighing plate 2 and the upper surface of the platform 1. The output terminal of the weighing sensor 8 is electrically connected to the input terminal of the PLC controller 4. The weighing sensor 8 adopts the weighing sensor commonly used in the prior art to detect the weight of the surface of the weighing plate 2.

[0029] The working principle of the automatic weighing and barcode reading device for express delivery provided by this utility model is as follows: In use, the express delivery is placed on the upper surface of the loading plate 51. The motor 59 is started by the PLC controller 4. The output shaft of the motor 59 drives the gear 58 to rotate. Through the meshing connection between the gear 58 and the external gear ring, the external gear ring drives the right-side turntable 57 to rotate. The right-side turntable 57 drives the rotating plate 56 to rotate. With the connection of the sliding plate 55, the left and right turntables 57 rotate synchronously. The sliding plate 55 drives the slide plate 54 to perform a counterclockwise circular motion. When the second rotation axis of the rotating plate 56 corresponds laterally to the second rotation axis of the turntable 57, the upper surface of the slide plate 54 and the upper surface of the loading plate 51 are in the same plane. As the slide plate 54 rotates, when the slide plate 54 protrudes from the upper surface of the loading plate 51, the slide plate 54 lifts the express delivery upwards and moves it slightly to the left. When the upper surface of the slide plate 54 and the upper surface of the loading plate 51 are once again in the same plane, the express delivery is placed back on the surface of the loading plate 51. The above operation is repeated, and the express delivery is automatically moved from right to left. During the movement, the tilt of the upper surface of the slide plate 54 is used to lift the express delivery, causing it to move towards the longitudinal center of the weighing plate 2 under the action of gravity, making the delivery trajectory more accurate. As the weighing plate 2 moves to the left, when the weighing plate 2 is placed on the upper surface of the weighing plate 2, the weight of the express delivery is applied to the detection end of the weighing sensor 8 through the weighing plate 2. The weighing sensor 8 is used to detect the weight of the express delivery. At the same time, the PLC controller 4 starts the barcode reader 3 to read the barcode information on the upper surface of the express delivery. After the barcode is read and the weight is weighed, as the express delivery continues to move to the left, the express delivery falls down from the slope of the unloading plate 52 into the external transfer frame.

[0030] It is worth noting that the PLC controller 4 disclosed in the above embodiments can be an NX7 model PLC controller, while the barcode reader camera 3, motor 59 and weighing sensor 8 can be freely configured according to the actual application scenario. The barcode reader camera 3 can be a TS25MCXP-85M model scanning camera, the motor 59 can be a GK97-86.52-YVP132M-4-7.5KW model corner motor, and the weighing sensor 8 can be an SLC610 model weighing sensor. The PLC controller 4 controls the operation of the barcode reader camera 3, motor 59 and weighing sensor 8 using methods commonly used in the prior art.

[0031] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
