Description

Technical Field

[0001] This utility model relates to the field of high-performance concrete production technology, specifically to a fully automatic fiber feeding station. Background Technology

[0002] In modern construction, transportation, and other engineering projects, high-performance concrete has been increasingly widely used due to its superior properties such as high strength and high durability. To further improve the crack resistance, toughness, and impact resistance of concrete, adding steel fibers during the concrete preparation process has become a crucial step.

[0003] However, the process of adding steel fibers to concrete is still mostly done manually. In this traditional mode, the addition process relies entirely on manual decision-making and execution. Operators must judge the timing and amount of steel fiber addition based on experience, which not only demands a high level of professional experience but also introduces significant subjectivity, making it difficult to guarantee the accuracy and consistency of the addition process, thus affecting the final performance and quality of the concrete. Furthermore, manual addition is extremely labor-intensive, requiring operators to repeatedly handle and add materials for extended periods, easily leading to fatigue. In addition, operators frequently come into contact with various mechanical equipment at the addition site, posing safety risks such as mechanical injury and dust inhalation, resulting in a high degree of danger and seriously threatening the health and safety of the operators. Utility Model Content

[0004] This invention provides a fully automatic fiber feeding station to solve the technical problems in the prior art.

[0005] To solve the above problems, the fully automatic fiber feeding station provided by this utility model adopts the following technical solution: it includes a feeding robot, which is equipped with a material clamp for gripping fiber bags;

[0006] Fiber bag trays, which are used to hold fiber bags, are stacked around the feeding robot;

[0007] The old bag recycling device is located on the side of the feeding robot and is used to recycle waste fiber bags.

[0008] A fiber vibrating feeder is installed on the side of the feeding robot. The fiber vibrating feeder is used to receive and feed metal fibers.

[0009] The bag-opening mechanism is located above the fiber vibrating feeder. The bag-opening mechanism is used to cut open the fiber bag so that the metal fibers inside the fiber bag fall onto the fiber vibrating feeder.

[0010] The discharge port of the fiber vibrating feeder is located in the middle of the upper part of the bidirectional conveyor, enabling the bidirectional conveyor to supply materials to two sets of mixing plants.

[0011] As a further improvement, the bag-opening mechanism includes a device frame and a bag-opening cutter mounted on the device frame.

[0012] As a further improvement, the bag-opening knife is connected to the equipment frame through a telescopic mechanism, so that the extended part of the bag-opening knife can be adjusted through the telescopic mechanism to prevent the failure of the robot arm to open the bag due to insufficient strength caused by the high strength of the steel fiber during the bag-opening process.

[0013] As a further improvement, the feeding robot is also equipped with a vision system, which is used to obtain the position and palletizing type of the fiber bag pallet so that the external control system can automatically plan the gripping path.

[0014] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0015] 1. This utility model basically realizes fully automatic feeding, effectively reducing the labor intensity of personnel, reducing employees' proximity to relatively dangerous mechanical equipment, reducing safety hazards, significantly reducing the occurrence of personnel injuries, and improving safety.

[0016] 2. This utility model effectively avoids clumping of steel fibers during the feeding process by using vibration feeding. In addition, weighing and feeding are controlled by an external control system, which has high weighing accuracy and improves the stability and quality of steel fiber concrete products.

[0017] 3. The components of this utility model are highly mature, the system integration threshold is low, and the practicality is good, which is conducive to its widespread use. Attached Figure Description

In the drawings, several embodiments of the present invention are shown by way of example and not limitation, and like or corresponding reference numerals denote like or corresponding parts, wherein:

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] In existing technologies, steel fiber feeding is mostly done manually or semi-automatically. The feeding process requires human decision-making and execution, which is labor-intensive and has a high risk factor.

[0024] To address the aforementioned issues, this invention achieves fully automated feeding of steel fiber by incorporating a high-maturity component.

[0025] Fiber bag pallets are used to hold fiber bags containing steel fibers. A forklift stacks these pallets around a feeding robot. The robot uses a vision system to acquire the position and stacking type of the fiber bag pallets and transmits this information to an external control system, which then autonomously generates a feeding path program. The feeding robot's material gripper places the fiber bags onto a bag-unpacking mechanism, which tears the bags, allowing the steel fibers to fall into a vibrating fiber feeder.

[0026] The fiber vibrating feeder has a built-in weighing function. It calculates the weight of material that can be fed through a program. When the fiber vibrating feeder is not working, the feeding robot continuously feeds material into the fiber vibrating feeder until its upper limit capacity is reached.

[0027] The fiber vibrating feeder uses subtraction metering. The feeder sends a feeding signal to the mixing plant control system and feeds the fiber to the bidirectional conveyor or directly onto the main conveyor belt of the mixing plant.

[0028] After introducing the basic principles of this utility model, various non-limiting embodiments of this utility model are described in detail below. Any quantity of elements in the accompanying drawings is for illustrative purposes only and not for limitation, and any naming is for distinction only and has no limiting meaning.

[0029] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0030] Example 1 of the fully automatic fiber feeding station provided by this utility model:

[0031] like Figure 1 As shown, the fully automatic fiber feeding station includes a feeding robot 4, a fiber bag tray 5, an old bag recycling device 6, a fiber vibrating feeder 1, a bag unpacking mechanism 2, and a bidirectional conveyor.

[0032] The feeding robot 4 is used to grab materials. The feeding robot 4 is equipped with a material gripper for grabbing fiber bags. In this embodiment, the feeding robot 4 is also equipped with a vision system 3. The vision system 3 adopts an industrial camera. The vision system 3 is used to obtain the position and palletizing type of the fiber bag tray 5 so that the external control system can automatically plan the grabbing path.

[0033] The fiber bag tray 5 is used to hold fiber bags, and the fiber bag tray 5 is stacked around the feeding robot 4; placing the fiber bags on the fiber bag tray 5 facilitates stacking.

[0034] The old bag recycling device 6 is located on the side of the feeding robot 4. The old bag recycling device 6 is used to recycle waste fiber bags. The old bag recycling device 6 achieves orderly recycling of old bags by squeezing, rotating and packing.

[0035] The fiber vibrating feeder 1 is located on the side of the feeding robot 4. The fiber vibrating feeder 1 is used to receive and feed metal fibers. The fiber vibrating feeder 1 can disperse the material during the conveying process to avoid clumping and ensure the quality of concrete.

[0036] The bag-opening mechanism 2 is located above the fiber vibrating feeder 1. The bag-opening mechanism 2 is used to cut open the fiber bag so that the metal fibers inside the fiber bag fall onto the fiber vibrating feeder 1. The bag-opening mechanism 2 includes a frame and a bag-opening cutter mounted on the frame. The bag-opening cutter can be a cutting tool or a blade.

[0037] In this embodiment, the bag-opening knife is connected to the equipment frame through a telescopic mechanism, so that the extended part of the bag-opening knife can be adjusted through the telescopic mechanism. In this embodiment, the telescopic mechanism adopts an electric telescopic structure.

[0038] By adjusting the extension length of the bag-opening blade using a telescopic mechanism, the bag-opening effect can be improved. If the extension length of the bag-opening blade is relatively short, the high strength of the steel fiber may cause insufficient force of the robotic arm during the bag-opening process, resulting in failure to open the bag. On the other hand, it can reduce damage to the bag-opening blade. If the extension length of the bag-opening blade is too long, the metal fiber may obstruct the flow, leading to an increased load on the bag-opening blade.

[0039] The outlet of the fiber vibrating feeder 1 is located in the middle of the upper part of the bidirectional conveyor, enabling the bidirectional conveyor to supply materials to both sets of mixing plants.

[0040] In this utility model, the feeding robot 4, the fiber vibration feeder 1, the old bag recycling device 6 and other devices are all relatively mature existing technologies. No improvements have been made to the above devices in this embodiment, and their specific structures will not be described in detail here.

[0041] While this specification has shown and described numerous embodiments of the present invention, it will be apparent to those skilled in the art that such embodiments are provided by way of example only. Many modifications, alterations, and alternatives will occur to those skilled in the art without departing from the spirit and intent of the present invention. It should be understood that various alternatives to the embodiments of the present invention described herein may be employed in the practice of the present invention. The appended claims are intended to define the scope of protection of the present invention and therefore cover the modular compositions, equivalents, or alternatives within the scope of these claims.
