[0025] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0026] The purpose of this embodiment is to provide an automatic loading device that can transport bulk materials from a placement platform to a drop point one by one, replacing manual labor, saving manpower, and improving feeding efficiency. It is suitable for loading non-magnetic, bulky, and soft materials. This embodiment also aims to provide an automatic mattress production line that includes the automatic loading device.

[0027] The following embodiments are described in detail with reference to the accompanying drawings. Furthermore, the embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the invention as set forth in the claims.

[0028] Please refer to the attached Figure 1-4 The present embodiment provides an automatic loading device, comprising a frame, a placement platform 1 for placing materials, and a conveying device for conveying materials to a drop point. The conveying device comprises a loading platform 2, a loading mechanism, and a conveying mechanism. The loading platform 2 is provided between the placement platform 1 and the drop point and extends along the direction from the placement platform 1 to the drop point. The loading mechanism is used to load materials from the placement platform 1 to one end of the loading platform 2, and the conveying mechanism conveys materials along the extension direction of the loading platform 2, that is, the direction from the placement platform 1 to the drop point, so that the materials move along the direction from the placement platform 1 to the drop point. After the materials are loaded to one end of the loading platform 2 by the loading mechanism, the materials can be completely moved to the loading platform 2 through the movement and conveying of the conveying mechanism, and then continue to move the materials to the other end of the loading platform 2. Finally, the materials are moved out of the loading platform 2 and fall to the drop point. The drop point can be the starting point for processing the materials or the starting end of the conveyor belt. The materials are automatically transported here and can be directly processed later.

[0029] In this way, the automatic loading equipment provided in this embodiment can automatically transfer and transport materials, and transport the materials from the placement platform 1 to the drop point one by one, replacing manual labor, completing the automatic loading operation, improving the feeding efficiency, and can provide stable support for the materials and perform smooth movement and transportation. It is especially suitable for conveying and loading block-shaped materials that are soft and difficult to grasp, such as sponge blocks, latex pads, etc.

[0030] Typically, multiple materials are stacked together on the placement platform 1, and the materials need to be transferred one by one to the loading platform 2 and transported one by one. Therefore, one of the loading platform 2 or the placement platform 1 can be raised and lowered to align the loading platform 2 with each stacked material, so that each material can be loaded onto the loading platform 2.

[0031] The loading mechanism that carries the material from the placement platform 1 to one end of the loading platform 2 can specifically include a pushing component arranged on the other side of the placement platform 1 and used to push the material onto the loading platform 2, such as a base that can be raised and lowered and connected to the frame, a retractable pushing rod connected to the base, a power device for driving the base to rise and fall, and a retractable power for driving the pushing rod to retract and extend. The power device and the retractable power can both be set as cylinders, and the pushing rod is located on the side of the placement platform 1 opposite to the loading platform 2, and retracts toward the loading platform 2, pushing the material that has been highly matched with the loading platform 2 onto the loading platform 2.

[0032] Alternatively, the loading mechanism may also include a pressing mechanism for pressing the material and a translation mechanism for driving the loading platform 2 to move back and forth in the direction of approaching or moving away from the placement platform 1. At the same time, the loading platform 2 includes a plate-shaped receiving end 201 for inserting under the material on the placement platform 1. The receiving end 201 is the end of the loading platform 2 close to the placement platform 1. First, the receiving end 201 of the loading platform 2 is made flush with the lower end surface of the material to be transported by lifting. Then, the translation mechanism drives the loading platform 2 to move in the direction close to the placement platform 1, and moves to the receiving end 201 of the loading platform 2 and inserts it under the material on the placement platform 1, picks up the end of the material and carries the material to the receiving end 201 of the loading platform 2. When the receiving end 201 is inserted under the material to be transported, in order to prevent the material from being moved by force and unable to be carried smoothly, the pressing mechanism can be used to press the material to be transported to prevent the material from moving, thereby ensuring that the loading platform 2 is in a stable state. Driven by the translation mechanism, it can be smoothly inserted under the material to be conveyed, such as between the top material and the next piece of material, and the end of the material to be conveyed can be lifted up so that the material is carried on the material receiving end 201; then the conveying mechanism drives the material to move to the other end of the loading platform 2, so that the material can be completely moved to the loading platform 2; after the material is conveyed, or during the conveying process of the material, the translation mechanism can also drive the loading platform 2 to move in the direction close to the drop point, and when the next material needs to be conveyed, the loading platform 2 is driven again to move toward the placement platform 1 and to the bottom of the next material.

[0033] The loading platform 2 can be plate-shaped at only the receiving end 201 or flat-shaped as a whole, so as to facilitate the movement of materials from the receiving end 201 to the other end close to the drop point and to be removed from the other end.

[0034] Specifically, the pressing mechanism includes a pressing block 3 , which is liftably connected to the frame. This pressing block 3 is positioned above the placement platform 1 and higher than the loading platform 2. Multiple pressing blocks 3 can be provided, distributed along the width of the loading platform 2. Each pressing block 3 is raised and lowered by a pneumatic cylinder, whose cylinder body is connected to the frame and whose piston rod is vertically positioned. Each pressing block 3 is connected to the piston rod of the cylinder directly or via a connecting plate 7.

[0035] like Figure 2 As shown, the translation mechanism includes a loading power 4 and a guide rail 5. The guide rail 5 is provided on the frame and extends in the same direction as the loading platform 2. The guide rail 5 may be provided with two, spaced apart along the width direction of the loading platform 2, and the loading platform 2 is slidably connected to the two guide rails 5. The loading power 4 is transmission-connected to the loading platform 2 and drives the loading platform 2 to move along the guide rail 5. The guide rail 5 may be a linear slide rail in the prior art. The translation mechanism also includes a sliding block 6 slidably connected to the guide rail 5 and a connecting plate 7 connecting the sliding block 6 and the loading platform 2. There are two guide rails 5, and correspondingly, there are also two connecting plates 7, which are respectively connected to the two side walls in the width direction of the loading platform 2. At the same time, the upper ends of the two connecting plates 7 are respectively connected to the sliding blocks 6 on the two guide rails 5, so that the loading platform 2 can be slidably mounted on the guide rails 5.

[0036] The transmission connection between the loading power 4 and the loading platform 2 can be configured as follows: the translation mechanism also includes a driving wheel and a driven wheel connected to the frame and spaced apart along the extension direction of the guide rail 5, and a belt or chain mounted on the driving wheel and the driven wheel. The loading power 4 can be configured as a motor, the power output shaft of the motor being connected to the driving wheel and driving the driving wheel to rotate, while the connecting plate 7 is connected to the belt or chain via a traction block 8 and translates with the belt or chain. The forward and reverse rotation of the motor can move the loading platform 2 back and forth between the placement platform 1 and the drop point.

[0037] The conveying mechanism includes two rotating rollers 16 spaced apart along the extending direction of the guide rail 5 and rotatably connected between the two connecting plates 7, a conveyor belt sleeved on the two rotating rollers 16, and a conveying power 15 connected to the rotating rollers 16 and driving the conveyor belt to move. The conveyor belt and the two rotating rollers 16 form or partially form the loading platform 2. The conveying power 15 is set as a motor, such as Figure 3 As shown, a drive shaft 17 and a rotating shaft are connected between the two connecting plates 7. The drive shaft 17, the rotating shaft, and a rotating roller 16 are connected by an endless belt. The motor is connected to the drive shaft 17 via the belt and drives the drive shaft 17 to rotate. The rotation of the drive shaft 17 drives the rotating roller 16 to rotate, thereby driving the conveyor belt to move. The drive shaft 17 can be located at the end of the conveyor belt near the placement platform 1 and outside the conveyor belt. The drive shaft 17, the rotating roller 16 at this end, and the conveyor belt at this end together form the material receiving end 201 of the loading platform 2.

[0038] A plurality of support rods 18 mounted between the two connecting plates 7 may be further provided between the transmission shaft 17 and the rotating shaft to provide auxiliary support.

[0039] To facilitate the insertion of the material receiving end 201 of the loading platform 2 under the material to be transported, the loading mechanism also includes a lifting assembly, which includes a lifting rod 19 arranged to be lifted and lowered in a vertical direction and a first lifting power that drives the lifting rod 19 up and down. The lifting rod 19 is hinged to the end of the loading platform 2 away from the placement platform 1 and can drive this end up and down. With this arrangement, when the material receiving end 201 of the loading platform 2 is inserted under the material, the other end of the loading platform 2 can be slightly lifted, so that the material receiving end 201 is slightly tilted downward, making it easier for the material receiving end 201 to be smoothly inserted between the two materials and allowing the material on the upper side to be loaded onto the material receiving end 201. The first lifting power can be set as a cylinder, the piston rod of the cylinder is arranged vertically and forms the lifting rod 19. In the preferred embodiment, not only is the piston rod end of the cylinder hinged to the loading platform 2, but the cylinder body of the cylinder opposite to the piston rod end is also hinged to the connecting plate 7. The end of the piston rod of the cylinder can be hinged to the rotating roller 16 away from the placement platform 1, and the connecting plate 7 is provided with a movable long hole for the rotating roller 16 to move up and down.

[0040] In this embodiment, Figure 4 As shown, of the loading platform 2 and the placing platform 1, the placing platform 1 is arranged to be liftable by a lifting mechanism, and the loading platform 2 is located above the lowest position of the placing platform 1 so as to be aligned with each stacked material.

[0041] The lifting mechanism includes two moving belts 10, each rotatably mounted on a frame and extending vertically, and a second lifting power 9 that drives the two moving belts 10 to move vertically. The two moving belts 10 are connected to either side of the placement platform 1. The frame is provided with two vertically distributed rotating shafts, both extending along the width of the loading platform 2. One rotating shaft is provided with a driving pulley at each end, while the other rotating shaft is provided with a driven pulley at each end. An annular moving belt 10 is provided on one driving pulley and the corresponding driven pulley on the same side. The second lifting power 9 is provided as a motor. The motor's power output shaft is in transmission connection with the rotating shaft provided with the driving pulley, driving the two driving pulleys to rotate synchronously, causing the two moving belts 10 to rotate synchronously, ensuring smooth lifting and lowering of the placement platform 1.

[0042] Materials are typically transferred in bulk to the placement platform 1 using a forklift or other device. To facilitate the placement platform 1 receiving materials, the automatic loading equipment in this embodiment also includes a sliding mechanism that drives the placement platform 1 to slide. This mechanism can move the placement platform 1 to a location with less interference from the machine frame, making it easier for a forklift to place the stacked materials onto the placement platform 1. Once the materials are unloaded, the sliding mechanism drives the placement platform 1 back to its original position, facilitating docking with the conveyor for loading.

[0043] like Figure 4 As shown, the sliding mechanism includes a support frame 12 connected between two moving belts 10, a driving pulley and a driven pulley arranged at intervals along the length or width direction of the placement platform 1 and rotatably connected to the support frame 12, a sliding belt 13 mounted on the driving pulley and the driven pulley, and a sliding force 13 connected to the driving pulley. The placement platform 1 is connected to the sliding belt 13 and moves with the sliding belt 13. The sliding belt 13 can be provided in multiple groups and distributed along the width or length direction of the placement platform 1. The support frame 12 can be a directional frame, and vertical support plates can be connected to both sides. The support plates are connected to the moving belts 10 in a one-to-one correspondence. The moving belts 10 drive the support frame 12 and the placement platform 1 to rise and fall as a whole. Each driving pulley can be mounted on the same rotating shaft, which is rotatably connected to the support frame 12. The sliding force 13 is set as a motor, fixed to the support frame 12 and connected to the rotating shaft. Along the extension direction of the slip belt 13, between the driving pulley and the driven pulley, a support cross column 13 is further provided on the support frame 12. A plurality of support cross columns 13 can be provided, distributed along the extension direction of the slip belt 13 and extending in a direction perpendicular to the slip belt 13 to provide auxiliary support.
