DETAILED DESCRIPTION

[0024] The specific embodiment of the utility model is described in detail below in connection with the drawings.

[0025] As Figures 1-5The utility model discloses an automatic package feeding device for stacked envelope logistics pieces, which aims to separate the stacked envelope logistics pieces one by one and improve the feeding rate of the envelope logistics pieces.

[0026] The automatic package feeding device for stacked envelope logistics pieces according to the utility model embodiment utilizes the conveying component to arrange and convey multiple groups of stacked flat pieces in a single column to the material separating platform. This orderly conveying mode avoids the chaotic accumulation of the material and provides a good foundation for subsequent splitting and processing, so that the whole feeding process is more smooth, and the efficiency of material processing is greatly improved. The feeding component is configured to split the stacked flat pieces on the material separating platform layer by layer. The uppermost flat piece of the stacked flat pieces on the material separating platform is moved to the code scanning station one by one by the grabbing mechanism, which realizes the accurate splitting and transfer of the stacked flat pieces by the feeding component, effectively avoids damage to the flat pieces caused by improper operation, ensures the integrity of the material, and ensures the smooth progress of the code scanning and subsequent conveying links. The stacked envelope logistics pieces are separated one by one, and the feeding rate of the envelope logistics pieces is improved.

[0027] As shown in Figure 1 In combination Figure 2 As shown, an automatic package feeding device for stacked envelope logistics pieces includes a conveying component 1 and a feeding component 2. The conveying component 1 is provided with a material separating platform 4 at the end. The conveying component 1 is configured to arrange multiple groups of stacked envelopes 6 in a single column and convey each group of stacked envelopes 6 to the material separating platform 4 one by one.

[0028] As shown in Figure 3 The feeding component 2 is arranged on one side of the conveying component 1. The feeding component 2 is provided with a code scanning station 5 below. The feeding component 2 is configured to split the stacked envelopes 6 on the material separating platform 4 layer by layer, and move the uppermost single envelope 7 of the stacked envelopes 6 on the material separating platform 4 to the code scanning station 5 one by one.

[0029] For example, the conveying component 1 is a step conveying structure. The step conveying structure can accurately control the distance and pause time of each conveying. When processing stacked flat pieces such as envelopes, it can ensure that each group of pieces can be accurately conveyed to the designated position of the material separating platform 4, avoid misalignment of the stacked pieces or failure of material separation due to deviation of the conveying distance, improve the accuracy and stability of the material conveying, and provide reliable protection for subsequent splitting, code scanning and other operations.

[0030] Different sizes, weight of flat object to transport requirements exist differences, step type conveying structure can be through the adjustment step length and frequency, easily adapt to the conveying needs of various materials. Whether it is light and thin envelope, or slightly thick card and other flat objects, can realize stable, efficient conveying, enhances the versatility and adaptability of the equipment for different materials.

[0031] As Figure 2 Combined Figure 4 As shown in the figure, the feeding component 2 includes a base 21 and a grabbing mechanism. The grabbing mechanism is installed above the distribution platform 4 through the base 21. The grabbing mechanism includes a suction cup assembly 22, a crank slider mechanism 23 and a power component 24. The suction cup assembly 22 is connected with the output end of the power component 24 through the crank slider mechanism 23.

[0032] Among them, the base 21 provides a stable support foundation for the whole grabbing mechanism, ensuring that the grabbing operation of the stacked envelope 6 can be carried out at the precise position, reducing the situation of grabbing failure or envelope damage caused by position deviation. The grabbing mechanism adopts the combination of the suction cup assembly 22, the crank slider mechanism 23 and the power component 24. The crank slider mechanism 23 can convert the rotary motion of the power component 24 into the linear reciprocating motion of the suction cup assembly 22. Through the precise mechanical structure design, the moving stroke and position of the suction cup assembly 22 can be accurately controlled, so as to realize the precise grabbing of the uppermost single envelope 7 of the stacked envelope 6. For example, the suction cup can be accurately positioned at the appropriate position of the envelope, ensuring that the suction force is uniformly distributed, stably grabbing the envelope, and avoiding the problems of loose grabbing or taking multiple envelopes.

[0033] As Figure 3 The side of the code scanning station 5 is provided with a feeding conveying table 3. The distribution platform 4, the code scanning station 5 and the feeding conveying table 3 are arranged in a straight line in turn. The grabbing mechanism is configured to move the uppermost single envelope 7 of the stacked envelope 6 on the distribution platform 4 to the code scanning station 5 in turn and then to the feeding conveying table 3.

[0034] The distribution platform 4, the code scanning station 5 and the feeding conveying table 3 are arranged in a straight line, which builds a very smooth operation streamline. The grabbing mechanism moves the single envelope 7 from the distribution platform 4 to the code scanning station 5 in sequence, and then moves to the feeding conveying table 3 after completing the code scanning. The whole process is completed in one breath, greatly reducing the transportation time and distance of the materials between different stations, and effectively improving the overall operation efficiency. This closely linked layout avoids the roundabout transportation and waiting time of the materials, so that the equipment can run continuously and efficiently.

[0035] According to some preferred embodiments of the present application, as Figure 4As shown, the suction cup assembly 22 is provided with a first gripping position 221 and a second gripping position 222. The suction cup assembly 22 is configured such that the first gripping position 221 grips a single envelope 7 on the material distribution platform 4, and the second gripping position 222 grips a single envelope 7 on the barcode scanning station 5. Driven by the power unit 24, the two gripping positions move from one side of the material distribution platform 4 to the side of the loading conveyor 3. The first gripping position 221 releases the gripped single envelope 7 onto the barcode scanning station 5, and the second gripping position 222 releases the gripped single envelope 7 onto the loading conveyor 3.

[0036] In this way, the suction cup assembly 22 has two gripping positions, enabling simultaneous gripping and releasing actions at different stages. While the first gripping position 221 grips envelopes on the sorting platform 4, the second gripping position 222 can work at the barcode scanning station 5, achieving parallel operation. Compared to a single gripping position design, this significantly reduces waiting time, multiplies the number of envelopes processed per unit time, and speeds up the entire logistics and packaging process. Furthermore, the first gripping position 221 and the second gripping position 222 correspond to the operations from the sorting platform 4 to the barcode scanning station 5 and from the barcode scanning station 5 to the loading conveyor 3, respectively, making the material flow path clear and continuous. This orderly flow method ensures close connection between each link, avoids material backlog or operational errors caused by process chaos, and enhances the smoothness of the entire automatic packaging device.

[0037] like Figure 5 As shown, the crank-slider mechanism 23 includes a connecting handle 231, a pull rod 232, a first guide rail 233, and a slide 234. One end of the connecting handle 231 is connected to the output end of the power component 24. The other end of the connecting handle 231 is connected to the pull rod 232. The first guide rail 233 is mounted on the base 21 and is arranged along the direction from the material distribution platform 4 to the barcode scanning station 5. The slide 234 is embedded in the first guide rail 233. A guide seat 235 is mounted on the slide 234. A guide groove is provided on the guide seat 235. The guide groove is arranged perpendicular to the first guide rail 233. The pull rod 232 is embedded in the guide groove. The suction cup assembly 22 is connected to the pull rod 232.

[0038] The connecting handle 231 converts the rotational motion of the power component 24 into the linear motion of the pull rod 232. With the constraint of the first guide rail 233 and the guide seat 235, the suction cup assembly 22 can move accurately from the material distribution platform 4 to the barcode scanning station 5 and then to the loading conveyor 3 along the preset route, ensuring that the position of each envelope grab and release is accurate and correct, effectively improving the accuracy and stability of the work.

[0039] The first guide rail 233 is installed on the base 21 to provide stable support and guidance for the sliding seat 234, reducing shaking and deviation during operation. The sliding seat 234 is embedded in the first guide rail 233, and the pull rod 232 is embedded in the guide groove of the guide seat 235. This multiple constraint structure enhances the stability of the entire mechanism, so that the suction cup assembly 22 can still run smoothly during high-speed movement and frequent start-stop, reducing the risk of failure to grasp or damage to the envelope due to vibration.

[0040] According to some preferred embodiments of the present application, the bottom of the material distribution platform 4 is provided with a lifting device. The lifting device is configured to be driven by the grasping mechanism to grasp the material layer by layer, and drive the material distribution platform 4 to rise layer by layer. As the grasping mechanism grasps the flat objects layer by layer, the lifting device drives the material distribution platform 4 to rise layer by layer, always keeping the uppermost layer of the material matching the best grasping position of the grasping mechanism. This avoids the need for the grasping mechanism to constantly adjust the height during grasping, reduces the action time of each grasping, improves the overall grasping efficiency, and thus speeds up the entire feeding and sorting process.

[0041] The material distribution platform 4 rises as the material decreases, ensuring that the material is always at a relatively stable height and position, reducing the risk of material spilling, scattering, and other situations caused by large changes in material height. Especially for light, thin and easily deformed stacked flat objects such as envelopes, a stable material state can ensure the integrity of the material during splitting and transfer, improving the reliability and accuracy of the operation.

[0042] At the same time, the cooperation of the lifting device and the grasping mechanism makes the material supply of the material distribution platform 4 and the material grasping of the grasping mechanism form a closely coordinated whole. This cooperative mode helps better link with subsequent code scanning, conveying and other links, ensures the coherence and smoothness of the work of each part of the entire feeding and sorting equipment, and improves the overall operation efficiency of the equipment.

[0043] According to some preferred embodiments of the present application, the code scanning station 5 is provided with a transparent supporting plate for carrying a single envelope 7. The transparent supporting plate can ensure that the envelope is in a flat and stable state during code scanning, avoiding the influence of envelope wrinkles and bending on logistics code identification. Moreover, the transparent material will not interfere with the light emitted and received by the code scanning equipment, and the light can penetrate the supporting plate without obstruction, ensuring that the code scanning equipment can clearly and accurately read the logistics code information, thereby improving the accuracy of code scanning and reducing sorting errors caused by code scanning errors.

[0044] The present application is not limited to the specific technical solutions described in the above embodiments. In addition to the above embodiments, the present application can also have other implementation manners. For those skilled in the art, any modification, equivalent replacement, improvement, etc. formed within the spirit and principles of the present application shall be included in the protection scope of the present application.
