Description

Technical Field

[0001] This invention relates to the field of feeding device technology, and in particular to a sheet feeding device. Background Technology

[0002] With the increasing level of production automation, the use of robotic arms and robots to automatically perform production tasks is becoming more and more common. Through automatic control systems, large-scale industrial production is truly achieved, labor intensity is reduced, and production efficiency is greatly improved. Sheet materials are a commonly used material in the field of mechanical production and processing. Current sheet material feeding methods typically involve manual feeding, requiring multiple operators to place and load the materials.

[0003] The shortcomings of the existing method are that, on the one hand, it is labor-intensive and time-consuming, and manual operation makes it difficult to ensure the continuity of material feeding, resulting in high labor costs. At the same time, errors are prone to occur during manual operation. Because the outer surface of the workpiece is smooth and the workpiece is mostly thin, overlapping is easy to occur during manual operation. Multiple workpieces of the same type may be picked up during picking, resulting in the problem of over-placing, which affects subsequent processing. Secondly, because it is difficult to ensure that the placement of each piece is the same during manual placement, it may cause inconsistencies in the positional accuracy of each piece when it is transferred to the next processing area, resulting in errors. Therefore, it affects subsequent production and even product quality. Summary of the Invention

[0004] Therefore, the technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a sheet feeding device that can realize automatic continuous feeding and is applicable to sheets of different sizes.

[0005] To solve the above-mentioned technical problems, the present invention provides a sheet feeding device, comprising,

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0033] Example

[0034] Reference Figure 1 As shown in Figure *, the present invention discloses a sheet feeding device, including a frame unit, the frame unit including a base 1 and a first side plate 11 and a second side plate 12 vertically disposed on the base 1, and the first side plate 11 and the second side plate 12 are parallel to each other.

[0035] The sheet feeding device further includes a storage unit located within the frame unit. The storage unit comprises a first support plate 21 and a second support plate 22 disposed opposite to each other, situated between the first side plate 11 and the second side plate 12. Each support plate is provided with a support assembly; the first support plate 21 has a first support assembly, and the second support plate 22 has a second support assembly. It should be noted that the first and second support assemblies have identical structures.

[0036] Specifically, taking the first support assembly as an example, the first support assembly includes a movable stop 20 and a first driving member 23. A mounting block 210 is embedded in the first support plate 21, and the mounting block 210 has a through hole. One end of the movable stop 20 passes through the through hole and contacts the sheet to be loaded, thereby supporting the sheet. A protrusion 201 is provided in the middle of the movable stop 20. An elastic member 202 is sleeved on the movable stop 20 between the protrusion 201 and the sheet to be loaded. A boss 211 is provided in the through hole near the end of the sheet to be loaded, and the elastic member 202 limits the movement. Between the boss 211 and the protrusion 201, the first driving member 23 abuts against the other end of the movable stop 20. The elastic deformation direction of the elastic member 202 is on the same horizontal line as the movement direction of the movable stop 20. Multiple sheets to be loaded are placed layer by layer on the movable stop 20 and are located between the first support plate 21 and the second support plate 22. The first support plate 21 and the second support plate 22 are in contact with both ends of the sheets to be loaded, and the planes of the first support plate 21 and the second support plate 22 are perpendicular to the plane of the sheets to be loaded.

[0037] The sheet feeding device further includes a discharge unit, which includes a conveying component and a second driving component 30. The conveying component is connected to the first support plate 21 and the second support plate 22 and is located below the first support component and the second support component. The second driving component 30 is connected to the conveying component and drives the conveying component to move along the discharge direction. The sheet to be fed falls from the storage unit to the conveying component and is conveyed to a designated position by the conveying component.

[0038] Therefore, it can be understood that the sheet feeding device protected by this invention includes a frame unit, a storage unit, and a discharge unit. Multiple sheets to be fed are stacked on the support components in the storage unit. When feeding is required, the first driving member moves upward, causing the movable stop block to move away from the sheet to be fed under the action of the elastic member. As a result, the sheet to be fed loses its support and falls to the conveying component. Then, the first driving member moves downward, pushing the movable stop block in the opposite direction. As a result, the movable stop block extends between the two support plates to support the next sheet to be fed, preventing it from falling further. The sheet that falls to the conveying component moves to the designated position along the discharge direction under the drive of the second driving member, thereby realizing the orderly feeding of one sheet at a time. Then repeat the above actions to feed the next sheet. With the sheet feeding device of the present invention, precise feeding of one sheet at a time can be achieved. In conjunction with the first driving component and the second driving component, continuous and precise feeding can be achieved. Compared with the existing manual feeding, the present invention can greatly improve the sheet feeding efficiency, reduce labor costs, and avoid sheet feeding overlap, thereby ensuring the smoothness of the subsequent production process and improving production efficiency.

[0039] Furthermore, the sheet feeding device also includes a pressing assembly, which includes a connecting frame 4 and a pressing rod assembly. The two ends of the connecting frame 4 are respectively mounted on the first support plate 21 and the second support plate 22. Specifically, the pressing rod assembly includes a pressing rod 41 movably connected to the connecting frame 4. The pressing rod 41 is located above the conveying assembly and can reciprocate along the height direction. The pressing rod 41 is used to press down the sheet to be fed, preventing it from tilting during operation on the conveying assembly. The height of the pressing rod 41 is adjustable. In actual operation, the distance between the pressing rod 41 and the conveying assembly is adjusted to allow only one sheet to pass through. This setting further avoids overlapping feeding, limits the number of sheets discharged each time, and ensures that only one sheet is fed at a time.

[0040] In addition, the pressure rod assembly also includes a guide wheel 42, which is located at one end of the pressure rod 41. When the pressure rod 41 comes into contact with the sheet to be loaded, the guide wheel 42 can make active contact with the sheet to be loaded, thereby avoiding scratching the sheet to be loaded.

[0041] Furthermore, the movable stop 20 also includes a first support portion 203 and a second support portion 204, which are respectively disposed at both ends of the protrusion 201. The elastic element 202 is sleeved on the second support portion 204. In a preferred embodiment, the elastic element 202 is a spring. The first support portion 203 is connected to the first driving member 23, and the second support portion 204 is in contact with the sheet to be loaded. It should be noted that the side of the first support portion 203 in contact with the first driving member 23 is an inclined surface, and the side of the second support portion 204 in contact with the sheet to be loaded is also an inclined surface. This facilitates the second support portion 204 in supporting the sheet to be loaded. It also facilitates the first driving member 23 in applying force to the movable stop 20.

[0042] In a preferred embodiment, the first driving member 23 is a driving cylinder. The push rod of the driving cylinder moves along the height direction. Accordingly, there are two first driving members 23, which are respectively disposed on the first support plate 21 and the second support plate 22.

[0043] In detail, the second driving component 30 includes a drive motor disposed on the frame unit. Specifically, the second driving component 30 is mounted on the second side plate 12. The output shaft of the drive motor is connected to the transmission assembly and drives the transmission assembly to operate.

[0044] Furthermore, the conveying assembly includes a first transmission shaft 31, a second transmission shaft 32, and a third transmission shaft 33 arranged horizontally, with the axial directions of the first transmission shaft 31, the second transmission shaft 32, and the third transmission shaft 33 perpendicular to the discharge direction. One end of the first transmission shaft 31 is provided with a first idler wheel 310, one end of the second transmission shaft 32 is provided with a second idler wheel 320, and one end of the third transmission shaft 33 is provided with a third idler wheel 330. The output shaft of the drive motor is provided with a synchronous pulley 34, and the synchronous pulley 34, the first idler wheel 310, the second idler wheel 320, and the third idler wheel 330 are connected by a belt 35.

[0045] In a preferred embodiment, the second support plate 22 is further provided with a fourth idler wheel 340, which is located below the second idler wheel 320. The belt 35 is sequentially wound around the first idler wheel 310, the fourth idler wheel 340, the second idler wheel 320, the third idler wheel 330 and the synchronous pulley 34 to form a rotation circuit.

[0046] The first idler wheel 310, the fourth idler wheel 340, the second idler wheel 320, the third idler wheel 330 and the synchronous wheel 34 are provided with a protective cover 120, which is disposed on the second side plate 12.

[0047] Specifically, the sheet feeding device further includes a width adjustment mechanism, which comprises a lead screw 50, a lead screw slider 51, and a knob 52. The lead screw slider 51 is movably connected to the lead screw 50. The lead screw 50 passes through the first support plate 21 and the second support plate 22, and the first support plate 21 is connected to the lead screw 50 via the lead screw slider 51. The knob 52 is located at one end of the lead screw 50. Rotating the knob 52 causes the first support plate 21 to move along the length of the lead screw 50, thereby adjusting the distance between the first support plate 21 and the second support plate 22 to accommodate sheets of different sizes to be fed.

[0048] In a preferred embodiment, the first support plate 21 and the second support plate 22 are respectively provided with a first guide groove 61 and a second guide groove 62 on opposite sides. The first guide groove 61 and the second guide groove 62 are symmetrically arranged, and the first guide groove 61 and the second guide groove 62 are configured to accommodate one sheet of the material to be loaded. The first guide groove 61 and the second guide groove 62 are located above the conveying assembly, and the extending direction of the first guide groove 61 and the second guide groove is in the same direction as the discharge direction.

[0049] In addition, the present invention also provides a pair of auxiliary support components, which are used to support and limit the sheet material to be loaded. Taking one of the auxiliary support components as an example, the auxiliary support component includes a support block 70 and an adjusting member. The bottom of the side of the support block 70 that contacts the sheet material to be loaded is provided with an arc angle 71, which can support the sheet material to be loaded. The adjusting member is mounted on the second support plate 22 and is connected to the support block 70. The support block 70 moves horizontally under the action of the adjusting member.

[0050] In detail, the adjusting component includes a housing 72, a guide screw 73, and a guide block 74. The housing 72 is connected to the first support plate 21. The extension direction of the guide screw 73 is in the same direction as the material discharge direction. The guide block 74 is connected to the guide screw 73 and can move along the extension direction of the guide screw 73. The guide block 74 is connected to the support block 70. Thus, the guide block 74 can drive the support block 70 to move along the extension direction of the guide screw 73. One end of the guide screw 73 is provided with a guide knob 75. By rotating the guide knob 75, the position of the support block 70 can be adjusted so that the support block 70 is in close contact with the sheet to be fed. It should be noted that the first support plate 22 is provided with the same auxiliary support assembly.

[0051] In summary, the sheet feeding device protected by this invention includes a frame unit, a storage unit, and a discharge unit. Multiple sheets to be fed are stacked on a support assembly within the storage unit. When feeding is required, a first driving member moves upward, causing a movable stop block to move away from the sheet to be fed under the action of an elastic member. As a result, the sheet to be fed loses its support and falls to the conveying assembly. Then, the first driving member moves downward, pushing the movable stop block in the opposite direction. The movable stop block then extends between two support plates to support the next sheet to be fed, preventing it from falling further. The sheet that falls to the conveying assembly moves along the discharge direction to a designated position under the drive of the second driving member, thereby achieving orderly feeding of one sheet at a time. Then repeat the above actions to feed the next sheet. With the sheet feeding device of the present invention, precise feeding of one sheet at a time can be achieved. In conjunction with the first driving component and the second driving component, continuous and precise feeding can be achieved. Compared with the existing manual feeding, the present invention can greatly improve the sheet feeding efficiency, reduce labor costs, and avoid sheet feeding overlap, thereby ensuring the smoothness of the subsequent production process and improving production efficiency.

[0052] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
