Description

Technical Field

[0001] The utility model relates to a U-turn mechanism technology, in particular to an online front-to-back U-turn mechanism. Background Art

[0002] In today's industrial production, there is a widespread demand for the front-to-back rotation of materials. Especially in the processing of soft bag packaging materials, ensuring the consistency of the front-to-back direction of the materials is crucial for subsequent processing steps.

[0003] However, existing front-to-back turning mechanisms present numerous practical challenges. Some conventional turning mechanisms, due to their inability to keep up with the material being conveyed from the front, can easily cause the material to overlap with the material being conveyed from the rear after the turn, or become stuck on the conveyor belt beneath the turning mechanism, severely impacting production efficiency. Furthermore, these conventional mechanisms can typically only turn 90°, requiring a baffle on the conveyor belt to block the rear end in order to complete a 180° turn. This method is not only complex to operate, but also significantly reduces speed during the turn, making it inefficient for efficient production.

[0004] Traditional forward and backward turning mechanisms have limitations in their structure and operation. For example, some mechanisms utilize a single servo motor fixed to a conveyor belt. If the servo motor rotates too fast for the material being conveyed at the front end, the material can become stuck on the conveyor belt, leading to equipment failure and production interruption. Furthermore, traditional mechanisms are difficult to adjust and adapt to materials of varying specifications, requiring complex parameter adjustments and mechanical component replacements, which increases operator workload and time costs.

[0005] In addition, the traditional front and rear turning mechanism has high requirements on the position and state of the material when turning the material. When the material is not in a straight line or is too skewed when it is transported, the vacuum suction cup on the turning device cannot suck the material to turn it around. Moreover, when the material is transported at an angle, if the position of the vacuum suction cup deviates, the suction cup will not be able to suck the material and the material will be thrown out, or the material will fall when it rotates halfway, resulting in blockage at the outlet, further affecting the smooth progress of production. In summary, the existing front and rear turning mechanisms have problems in actual application such as slow turning speed, easy material jamming, complicated operation, high requirements on material position, and difficulty in adapting to materials of different specifications. In order to solve these problems, there is an urgent need for a new type of online front and rear turning mechanism that can achieve accurate and fast turning of materials without affecting the conveying speed, thereby improving production efficiency and product quality. Utility Model Content

[0006] The purpose of the utility model is to provide an online front-to-back turning mechanism to solve the above-mentioned deficiencies in the prior art.

[0007] In order to achieve the above object, the utility model provides the following technical solutions: an online front-to-back turning mechanism, comprising a base, a conveying mechanism is provided above the base, the conveying mechanism is used to convey materials, and the conveying mechanism comprises a material conveyor belt;

[0008] A visual inspection mechanism is installed above the conveying mechanism and is used to perform visual scanning and inspection on the material being conveyed. The visual inspection mechanism includes a visual inspection camera.

[0009] Furthermore, the conveying mechanism also includes a support frame fixedly connected to the top of the base, and a driving roller and a driven roller are rotatably connected between the support frames. The material conveying belt transmission sleeve is arranged on the outside of the driving roller and the driven roller.

[0010] Furthermore, the visual inspection mechanism also includes a first support rod fixedly connected to the top of the base, an adjustable movable frame is fixedly connected above the first support rod, and the visual inspection camera is fixedly connected to the adjustable movable frame by bolts.

[0011] Furthermore, a second support rod is fixedly connected to the top of the base, a servo linear module is fixedly connected to the second support rod, and a turning device is provided on one side of the servo linear module.

[0012] Furthermore, the turning device includes a first slide and a second slide, one side of the first slide and the second slide are respectively slidably connected to the servo linear module, and the first slide and the second slide are located above the material conveyor belt.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] First, it excels in improving production efficiency. This mechanism employs a servo linear module and two reversing devices to work in tandem. When the visual inspection camera detects that a material needs to be reversing, the reversing device quickly activates, with a pneumatic cylinder pressing down on the vacuum suction cup to grip the material and rotate it. Simultaneously, the servo linear module follows suit, maintaining a speed equal to that of the conveyor belt, ensuring that the material does not become stuck or lose speed during the reversal process. Furthermore, when two conveyed materials need to be reversed consecutively, reversing devices A and B operate alternately, greatly improving reversal efficiency and effectively increasing production speed.

[0015] Secondly, the accuracy and stability of the turning process are guaranteed. The visual inspection camera accurately detects the forward and backward direction of the material and feeds the signal back to the turning mechanism and servo linear module, ensuring that the turning mechanism can accurately grasp the material and turn the material. Furthermore, the turning mechanism can be fine-tuned up and down according to the thickness of the material. A material guide guard installed at the front of the conveyor belt guides the material and prevents it from tilting. This improves the turning mechanism's material suction accuracy and reduces the possibility of errors.

[0016] Furthermore, it offers excellent adaptability and practicality. This mechanism boasts a simple and scientific design, a straightforward structure, and easy adjustments, adapting to various soft bag packaging specifications. The visual inspection camera is easily adjustable, allowing for precise positioning and parameter adjustments based on the material. Furthermore, the follow-up reversal design makes this mechanism even more flexible in material handling, making it suitable for a wider range of products.

[0017] Finally, this mechanism offers significant energy-saving advantages. By matching the conveyor belt speed during reversing, it reduces energy waste. Furthermore, its stable operation reduces equipment maintenance costs and failure rates, saving companies money. In short, this in-line reversing mechanism provides an efficient, accurate, and stable solution for reversing flexible bag packaging materials. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] See also Figure 1-3 An online front-to-back turning mechanism is mainly composed of a base 7 and various components installed on the base 7.

[0026] The base 7 serves as a solid support foundation for the entire mechanism, providing a stable installation platform for the components above. A conveying mechanism is provided above the base 7, which is mainly used for efficiently conveying materials. The conveying mechanism includes a material conveyor belt 1, which plays a key role in the process of conveying materials. In addition, the conveying mechanism also includes a support frame 9 fixedly connected to the top of the base 7. The support frame 9 is firm and reliable, and an active roller and a driven roller are rotatably connected therebetween. The transmission sleeve of the material conveyor belt 1 is arranged on the outside of the active roller and the driven roller. The rotation of the active roller drives the driven roller and the material conveyor belt 1 to operate together, ensuring that the material can be smoothly conveyed forward.

[0027] The visual inspection mechanism is mounted above the conveyor mechanism and is primarily used for precise visual scanning and inspection of conveyed materials. It includes a visual inspection camera 2, bolted to an adjustable movable frame, which in turn is secured to a first support rod 8 fixedly connected to the top of the base 7. This design allows the visual inspection camera 2 to be flexibly adjusted in position and angle to suit different materials and inspection requirements, significantly improving inspection accuracy and adaptability.

[0028] A second support rod is also fixedly connected to the top of the base 7, and the servo linear module 3 is fixedly connected to the second support rod. The servo linear module 3 has high-precision linear motion control capabilities, which provides a strong guarantee for the precise operation of the entire mechanism. A turning device 4 is provided on one side of the servo linear module 3, and the turning device 4 includes a first slide 5 and a second slide 6. One side of the first slide 5 and the second slide 6 are respectively slidably connected to the servo linear module 3, and the first slide 5 and the second slide 6 are located above the material conveyor belt 1. This design allows the turning device 4 to perform precise linear motion under the drive of the servo linear module 3, thereby realizing accurate turning operations on the material.

[0029] Working Principle: Material is first placed on the material conveyor belt 1. Driven by the driving and driven rollers, the material conveyor belt 1 conveys the material forward. When the material passes under the visual inspection camera 2, the visual inspection camera 2 visually scans the material to determine its front-to-back orientation. If the visual inspection camera 2 detects that the material needs to turn, a signal is transmitted to the turning device 4 and the servo linear module 3. At this time, the cylinder in the turning device 4 quickly presses down, and the vacuum suction cups suck the material and rotate it to turn. Simultaneously, the corresponding slide of the servo linear module 3 (such as the first slide 5 or the second slide 6) is driven by the servo motor to follow the material conveyor belt 1, completing a tracking motion. After the turn is completed, the slide returns to its original position. If two conveyed materials need to be turned back in succession, the first slide 5 and the second slide 6 of the turning device 4 operate alternately to ensure that the materials can be turned quickly and accurately. Finally, the materials continue to be conveyed by the material conveyor belt 1 to the next process.

[0030] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
