Description

Technical Field

[0001] This utility model relates to the field of profile cutting and feeding, specifically to a rigid automatic feeding device. Background Technology

[0002] Aluminum door and window processing is rapidly entering the stage of automated production, and various production lines and workstations are emerging, such as sawing and milling lines and sawing and milling workstations. The initial stage of the process logic in these production lines involves automatic feeding, where manual labor involves placing raw materials one by one into the feeding mechanism in the loading area. The feeding mechanism then cyclically feeds the material to the gripping position of the feeding robot before proceeding to the next step of automated production. Existing automatic feeding structures all use synchronous belt drives. Synchronous belt drives are flexible drives, and therefore possess the technical characteristics that flexible drives cannot avoid. Specifically, in the door and window profile processing industry, due to the technological development of the door and window industry in recent years, the specifications of corresponding thermally broken aluminum profiles have also gradually changed. On the one hand, the difference in cross-sectional dimensions is getting bigger and bigger, and on the other hand, the number of irregular profiles and reinforced profiles is getting bigger and bigger. This has led to the increasing disadvantages of flexible transmission. On the one hand, flexible transmission is prone to shaking during the transmission process, which has a great impact on the feeding stability of irregular profiles or profiles with irregular bottom surfaces, and may even prevent the feeding of irregular profiles, greatly reducing the utilization rate of the production line. On the other hand, synchronous belt conveyors have fixed partition sizes, but now, due to the increasing difference in the size of profile cross-sections, the adaptability is very poor. If the spacing is large, the small cross-section profiles will tilt during transmission due to shaking, resulting in the final positioning failure. If the spacing is small, large cross-section profiles cannot be put in.

[0003] Therefore, in order to solve the above-mentioned problems, a rigid automatic feeding device is proposed. Utility Model Content

[0004] This utility model addresses the problems mentioned above by designing a rigid automatic feeding device. This device can effectively achieve step-by-step rigid feeding, has a compact structure, high stability, and can be adapted to profiles of different sizes, greatly improving product utilization.

[0005] To achieve the above objectives, this utility model provides a rigid automatic feeding device, comprising several feeding units and a driving mechanism. The feeding units are supported on the ground and their ends are connected to the feeding area of ​​the machine tool frame. Each feeding unit includes a fixed feeding frame and a movable feeding frame. One of the feeding units is provided with the driving mechanism for driving the movable feeding frame to reciprocate. A linkage mechanism is provided at the lower part of the feeding unit, and the feeding units are connected to each other through the linkage mechanism. Limiting protrusions are provided at the top of both the fixed feeding frame and the movable feeding frame, and the profile is placed between the limiting protrusions.

[0006] In the above manner, the profile is placed on the feeding unit. The number of feeding units can be selected according to the length of the profile to provide sufficient support for the profile. The moving feeding frame, driven by the drive mechanism, makes a reciprocating motion of rising and moving forward while falling and moving backward, thus driving the profile on it to move. When the profile falls after rising and moving forward, it will land on the fixed feeding frame, where the limiting protrusions limit the profile, thus causing the profile to move forward one step. This process is repeated to place more profiles on it, and the profiles will move forward step by step, entering the loading area of ​​the machine tool frame in an orderly manner.

[0007] Furthermore, the fixed feeding rack includes: a bracket, a fixed support plate, a linear guide rail, and a mounting plate. The fixed support plate is connected to the upper part of the bracket, and the fixed support plate is provided with spaced-apart limiting protrusions. The linear guide rail is fixedly connected to the side of the bracket, and the movable feeding rack is slidably connected to the side of the bracket through the linear guide rail. The mounting plate is connected to the front end of the bracket and is connected to the machine tool frame.

[0008] Furthermore, the mobile feeding rack includes: a lifting cylinder, an adjusting plate, a moving support plate, a guide rail slider, and a connecting plate. The guide rail slider is fixedly connected to the side of the connecting plate and slidably connected to the linear guide rail. The lifting cylinder is fixedly connected to the other side of the connecting plate, and the adjusting plate is fixedly connected to the upper part of the lifting cylinder. The moving support plate is connected to the adjusting plate, and the upper surface of the moving support plate is provided with spaced-apart limiting protrusions. The output end of the driving mechanism is connected to the connecting plate, and the linkage mechanism is mounted on the connecting plate.

[0009] Furthermore, the drive mechanism also includes a cylinder seat and a feeding cylinder. The cylinder seat is installed at the rear end of the bracket, the feeding cylinder is installed on the cylinder seat, and the output end of the cylinder seat is connected to the connecting plate.

[0010] Through the combined movement of the lifting cylinder and the feeding cylinder described above, the moving pallet can be driven, causing the profiles on it to move and achieving "step-by-step" transportation. The feeding cylinder pushes the connecting plate to move linearly, and the connecting plate drives the feeding pallet on it to move.

[0011] Furthermore, the linkage mechanism includes: a rack, a drive shaft, a gear, and a bearing housing. The rack is fixedly connected to the side of the connecting plate, the bearing housing is fixedly connected to the lower part of the bracket, the drive shaft is rotatably connected to the bearing housing, the gear is connected to the drive shaft, and the gear is connected to the rack.

[0012] In this way, when the feeding cylinder pushes the connecting plate, the connecting plate drives the rack to move, the rack drives the gear to move, the gear drives the transmission shaft to rotate, and the transmission shaft synchronously drives the other gears on it to rotate, which in turn drives the racks and connecting plates on other feeding units that do not have a drive mechanism to move linearly.

[0013] Furthermore, the fixed tray includes a fixed plate one and a fixed plate two, and the movable tray includes a movable plate one and a movable plate two. The fixed plate one and the fixed plate two are detachably connected to the bracket, and the movable plate one and the movable plate two are detachably connected to the adjusting plate.

[0014] In summary, this utility model has the following advantages and beneficial technical effects:

[0015] 1. This utility model provides a rigid automatic feeding device to replace flexible transportation. By using rigid feeding, it can improve the utilization rate of products. It has a compact structure, high stability, and can adapt to profiles of different sizes.

[0016] 2. The rigid automatic feeding device of this utility model, through a linkage mechanism and a feeding cylinder, can synchronously realize the movement of each feeding unit, which improves the synchronization of the overall structure and saves production costs. Attached Figure Description

The lifting cylinder 21 is fixedly connected to the other side of the connecting plate 25 by bolts. The lifting cylinder 21 is placed vertically and its output end moves in the vertical direction.

The upper surface of the moving support plate 23 is provided with spaced limit protrusions 15. The output end of the drive mechanism 3 is connected to the connecting plate 25, and the linkage mechanism 37 is installed on the connecting plate 25.

[0034] like Figure 1 , Figure 2 and Figure 3As shown, the fixed support plate 12 includes a first fixed plate 121 and a second fixed plate 122, and the movable support plate 23 includes a first movable plate 231 and a second movable plate 232. Both the first fixed plate 121 and the second fixed plate 122 are detachably connected to the bracket 11 by bolts. The bracket 11 has a long groove.

Similarly, the movable support plate 23 is adjusted in the same way.

[0039] S2. Place the profile on the pallet, and then start the drive mechanism 3;

[0040] S3, lifting cylinder 21 lifts the profile, feeding cylinder 32 pushes the moving pallet 23 forward, and the profile moves accordingly. When the feeding cylinder 32 pushes forward, the power is transmitted to the moving pallet 23 of another feeding unit 5 through the linkage of rack 33, gear 35 and transmission shaft 34.

[0041] S4. The lifting cylinder 21 descends, placing the profile between the limiting protrusions 15 on the fixed support plate 12. The feeding cylinder 32 retracts, causing the moving support plate 23 to reset.

[0042] S5. Place the new profile in the starting position;

[0043] S6. Repeat S3, S4 and S5 until the first batch of profiles is delivered to the loading area on the machine tool frame 4.

[0044] S7. Repeat S5 and S6 to form a work cycle.

[0045] In the mode of separating the fixed material support area and the movable lifting area, a lifting action and a forward and backward movement are added to the movable lifting area. When the movable lifting area lifts, the profile can be completely separated from the fixed material support area. When the lifting area falls, because it is lower than the fixed area, the profile can be completely separated from the lifting area. Based on this, the rigid feeding of the profile can be achieved by combining the forward and backward movement, that is, the transmission logic of "moving forward step by step".

[0046] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
