Description

Technical Field

[0001] This utility model relates to the field of packaging box production equipment technology, and in particular to a material feeding system. Background Technology

[0002] In the packaging box manufacturing industry, sheet material (sheet stock) is an important raw material in the packaging box production process. Its automated feeding process occupies a key position in the entire production line, directly affecting the continuity of production, efficiency and cost control.

[0003] In traditional packaging box production lines, sheet metal feeding typically employs a "dual-bin switching + robotic arm suction-type loading and unloading" solution. The basic principle of this solution is to set up two bins. When the sheet metal in one bin is depleted, the system switches to the other bin to continue feeding, while simultaneously replenishing empty bins. The robotic arm is responsible for grabbing the sheet metal from the top of the bins and placing it at the subsequent processing station.

[0004] However, this "dual hopper switching + robotic arm suction-type material handling" solution still has the following problems: 1. During material switching, the production line needs to be paused to ensure production safety and accurate board supply. Although each interruption is short, the cumulative time loss caused by frequent switching is significant, greatly reducing production efficiency and making it difficult to meet the high-efficiency production needs of modern packaging box manufacturers.

[0005] 2. A lifting mechanism needs to be installed in the hopper to continuously lift the sheet material upwards, so that the robotic arm can smoothly grab the sheet material from the top of the hopper. This makes the hopper structure complex and the equipment cost high.

[0006] 3. The sheet metal may have a certain positional deviation in the hopper. After the robotic arm picks up the material, it still needs to perform a positioning operation. This not only increases the number of operation steps, but also reduces the overall production efficiency and affects the smoothness of subsequent processing procedures.

[0026] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] Figure 1 A schematic diagram of a feeding system 100 according to an embodiment of the present invention is shown below. Figure 1 Provide a detailed description.

[0028] like Figure 1 As shown, the feeding system 100 can be used to provide various types of sheet materials (hereinafter referred to as "sheet materials"). These sheet materials are diverse in material and use, such as cardboard, plastic sheets, thin metal sheets, composite material sheets, etc., used for making packaging boxes, or sheet materials suitable for other printed products.

[0029] The feeding system 100 mainly includes a platform 110, a hopper 120, a material handling device 130, and a positioning device 140, wherein the hopper 120 is located on one side of the platform 110. Figure 1 (on the right side of the image), and the hopper 120 is significantly higher than the platform 110. Figure 2 A schematic diagram of a hopper 120 according to an embodiment of the present invention is shown. Figure 1 and Figure 2 As shown, the hopper 120 includes a storage chamber 121, an inlet 122, an outlet 123, and one or more retaining members 124. The storage chamber 121 is configured to store sheet metal, for example in... Figure 1 In the illustrated embodiment, sheet metal can be neatly stacked along a first direction in the storage cavity 121. The discharge port 123 is located on the side of the storage cavity 121 near the platform 110. Simultaneously, the bottom surface of the storage cavity 121 is inclined (the first end of the bottom surface near the platform 110 is significantly lower than the end away from the platform 110), so that the sheet metal in the storage cavity 121 can automatically slide towards the discharge port 123 under the influence of gravity. Furthermore, a baffle 124 is located at the discharge port 123 to control the output of the sheet metal and prevent it from leaving the storage cavity 121 by itself from the discharge port 123.

[0030] like Figure 1 As shown, the material handling device 130 is positioned between the platform 110 and the hopper 120, while the positioning device 140 is mounted on the platform 110. Through the cooperation of the material handling device 130 and the positioning device 140, rapid material handling and precise positioning of the sheet metal can be achieved. Specifically, the material handling device 130 mainly includes a suction cup 131 and an actuator 132. The actuator 132 can drive the suction cup 131 to switch between the material handling position and the material dispensing position, thereby realizing automated material handling operations. Specifically, when the suction cup 131 is in the material handling position, it is aligned with the outlet 123 of the hopper 120 and can reliably pick up the sheet metal from the hopper 120. When the suction cup 131 switches from the material handling position to the material dispensing position, thanks to the elastic deformation of the sheet metal or the retaining member 124, the suction cup 131 can smoothly remove the sheet metal from the hopper 120 (storage chamber 121). When the suction cup 131 is in the feeding position, it is located directly above the stage 110 and can place the sheet material onto the upper surface of the stage 110. After the sheet material is placed on the stage 110, the positioning device 140 can position the sheet material, thereby reducing the additional positioning operations caused by the deviation of the sheet material position in subsequent processing, which is conducive to improving production efficiency and optimizing the production process.

[0031] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the discharge port 123 is a rectangular opening, and correspondingly, four baffles 124 are provided, which are respectively located at the four corners of the discharge port 123. Preferably, the baffles 124 are elastic sheets, so that the material handling device 130 can more easily remove the sheet material from the storage cavity 121.

[0032] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the feed inlet 122 can be located at the top of the storage cavity 121 to facilitate workers adding sheet metal to the storage cavity 121 and to facilitate workers organizing the sheet metal in the storage cavity 121. In some embodiments, the feed inlet 122 can also be located on the side of the storage cavity 121 away from the platform 110. It is easy to understand that in some embodiments, the feed inlet 122 can also be located at both the top of the storage cavity 121 and the side away from the platform 110.

[0033] According to one embodiment of the present invention, such as Figure 1 and Figure 2As shown, the hopper 120 may also include a counterweight 125. The counterweight 125 is disposed in the storage cavity 121 and can slide along the inclined direction of the bottom surface, thereby pushing the sheet material towards the discharge port 123 to ensure that the sheet material moves smoothly towards the discharge port 123.

[0034] In some embodiments, the bottom surface of the storage cavity 121 is provided with an elongated mounting hole 126, and an inclined guide rod 127 (or a guide rail, etc.) is provided below the storage cavity 121. A portion of the counterweight 125 passes through the mounting hole 126 and slides in engagement with the guide rod 127. The guide rod 127 provides guidance for the sliding of the counterweight 125, ensuring that the counterweight 125 moves smoothly along a predetermined trajectory, thereby more effectively pressing the sheet metal and allowing the sheet metal to slide smoothly towards the discharge port 123.

[0035] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the counterweight 125 includes a magnetically attractive material. The hopper 120 also includes a magnet 128, which is disposed in the storage chamber and away from the discharge port 123. The magnet 128 can be used to temporarily fix the counterweight 125 to facilitate workers to add sheet metal into the discharge chamber.

[0036] In some embodiments, the magnet is fixedly mounted by a bracket at one end of the bottom surface of the storage chamber away from the discharge port 123 (i.e., the opposite side near the stage 110).

[0037] In some embodiments, the counterweight 125 is made entirely of a magnetically pleasing material (e.g., iron). In other embodiments, the main structure of the counterweight 125 is made of a lightweight and stable conventional material (e.g., aluminum, stainless steel, plastic, etc.) to prevent corrosion. Meanwhile, a magnetically pleasing material (e.g., an iron sheet) is fixed to the main structure of the counterweight 125 to ensure reliable attraction between the counterweight 125 and the magnet 128.

[0038] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the hopper 120 may also include a through-beam photoelectric sensor 129, which is mainly used to detect whether there is a shortage of material in the storage chamber 121. Specifically, the through-beam photoelectric sensor 129 may include a transmitter 129a and a receiver 129b. The transmitter 129a is located on one side of the storage hopper 120 (e.g., Figure 1 (e.g., the front side of the storage bin 120), the receiving end 129b is located on the other side of the storage bin 120 (e.g., the front side of the storage bin 120). Figure 1The transmitter 129a and receiver 129b are both located near the discharge port 123 (e.g., 3-8 cm from the discharge port). During operation, the transmitter 129a emits a detection beam towards the receiver 129b. When the storage chamber 121 contains a large amount of sheet metal, the detection beam is blocked by the sheet metal. When the storage chamber 121 is low on material, the detection beam will directly reach the receiver 129b, which receives the complete detection beam and outputs a material shortage signal. The equipment control system can then alert workers to replenish the sheet metal via sound or light upon receiving the material shortage signal.

[0039] Figure 3 A schematic diagram of a material handling device 130 according to an embodiment of the present invention is shown. Figure 1 and Figure 3 As shown, the actuator 132 mainly includes a mounting plate 132a, a guide seat 132b, a connecting rod 132c, a guide shaft 132d, a swing arm 132e, and a rotary drive module 132f. The mounting plate 132a is fixedly connected to the side of the hopper 120 (e.g., Figure 1 The guide seat 132b is connected to the front side of the mounting plate 132a via a first rotating shaft 132g, and a guide hole 132b-1 is provided on the guide seat 132b. The first end of the connecting rod 132c is fixedly connected to the suction cup 131, and the second end is provided with a through hole 132c-1. The guide shaft 132d is slidably passed through the guide hole 132b-1 and the through hole 132c-1. Preferably, a limit head is provided at the upper end of the guide shaft 132d (the end near the guide hole 132b-1) to prevent the guide rod from falling off. At the same time, the first end of the swing arm 132e is connected to the front side of the mounting plate 132a via a second rotating shaft 132h, and the second end of the swing arm 132e is rotatably connected to the second end of the connecting rod 132c (e.g., rotatably connected via a bearing). The rotary drive module 132f is connected to the swing arm 132e and can drive the swing arm 132e to swing around the second rotating shaft 132h, thereby causing the suction cup 131 to switch between the picking position and the discharging position. In this embodiment, the rotary drive module 132f adopts a geared motor (a motor with a reducer), wherein the output shaft of the geared motor serves as the second rotating shaft 132h and is fixedly connected to the swing arm 132e. In other embodiments, the rotary drive module 132f may also adopt a common motor (a motor without a reducer), a pneumatic motor, a hydraulic motor, or a rotary electromagnet, etc., which will not be described in detail here.

[0040] In some embodiments, the actuator can also be implemented using a robotic arm, such as a Cartesian coordinate system robotic arm or a spherical coordinate system robotic arm. These robotic arms can also drive the suction cup to switch between the picking and unloading positions, but their switching speed is slightly slower. Figure 3The actuator shown.

[0041] Figure 4 A schematic diagram of a platform 110 and a positioning device 140 according to an embodiment of the present invention is shown. Figure 1 and Figure 4 As shown, the positioning device 140 may include a first positioning member 141 and a first pushing module 142 arranged at intervals along a first direction. The first positioning member 141 is fixed on the upper side of the platform 110. The first pushing module 142 is mounted on the platform 110 and configured to push the sheet material along the first direction so that the sheet material is against the first positioning member 141, thereby realizing the positioning of the sheet material in the first direction.

[0042] In some embodiments, the first pushing module 142 mainly includes a first push plate 142a and a first linear actuator 142b. Correspondingly, a first receiving hole 111 is provided on the stage 110, and the first push plate 142a passes through the first receiving hole 111. The first linear actuator 142b is mounted on the lower side of the stage 110 and connected to the first push plate 142a. The first linear actuator 142b can drive the first push plate 142a to move along a first direction, thereby enabling the first push plate 142a to push the sheet material along the first direction.

[0043] According to one embodiment of the present invention, such as Figure 1 and Figure 4 As shown, the positioning device 140 may further include a second positioning member 143 and a second pushing module 144 arranged at intervals along the second direction. The second positioning member 143 is fixed on the upper side of the platform 110. The second pushing module 144 is mounted on the platform 110 and configured to push the sheet material along the second direction so that the sheet material abuts against the second positioning member 143, thereby realizing the positioning of the sheet material in the second direction.

[0044] In some embodiments, the second pushing module 144 mainly includes a second push plate 144a and a second linear actuator 144b. Accordingly, a second receiving hole 112 is provided on the stage 110, and the second push plate 144a passes through the second receiving hole 112. The second linear actuator 144b is mounted on the lower side of the stage 110 and connected to the second push plate 144a. The second linear actuator 144b can drive the second push plate 144a to move in a second direction, thereby enabling the second push plate 144a to push the sheet material in the second direction.

[0045] According to one embodiment of the present invention, such as Figure 1 and Figure 4As shown, the feeding system 100 may further include a photoelectric sensor 150, which is configured to project a detection beam onto the stage 110 to detect whether there is a sheet material on the stage 110. In some embodiments, a light-transmitting hole 113 is provided on the stage 110, located within the area enclosed by the first positioning member 141, the first push plate 142a, the second positioning member 143, and the second push plate 144a. Accordingly, the photoelectric sensor 150 is disposed in or directly below the light-transmitting hole 113 and projects a detection beam upward to detect whether a sheet material is placed on the stage 110. Specifically, when a sheet material is placed on the stage 110, the detection beam emitted by the photoelectric sensor 150 will be reflected by the sheet material. At this time, the photoelectric sensor 150 can capture the reflected light, thereby determining that a sheet material is present on the stage 110. Conversely, if no sheet metal is placed on the stage 110, the photoelectric sensor 150 will not be able to detect the reflected light, thus determining that there is no sheet metal on the stage 110.

[0046] Compared with the prior art, the embodiments of this utility model provide a feeding system 100, wherein by tilting the bottom surface of the storage cavity (the end of the bottom surface near the platform 110 is lower than the end away from the platform 110) and setting the discharge port 123 on the side of the storage cavity 121 near the platform 110, the sheet material can automatically slide towards the discharge port 123 under the action of gravity, thereby significantly simplifying the structure of the hopper 120 and reducing equipment costs. In addition, through the cooperation of the picking and placing device 130 and the positioning device 140, rapid picking and placing and precise positioning of the sheet material are achieved, effectively reducing the additional positioning operations caused by the position deviation of the sheet material in subsequent processing, improving production efficiency, and further optimizing the production process.

[0047] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
