Description

Technical Field

[0001] The present invention relates to a connecting and discharging extruder, an extruder discharging connection system and method, and belongs to the technical field of extruder discharging transfer. Background Art

[0002] Before some rubber materials are used, the rubber materials need to be plasticized by an extruder and formed by extrusion. Common extruders only have standardized plasticizing and forming functions and do not have auxiliary functions such as automatic material taking. The discharging and transfer mainly rely on forklifts and manual labor, resulting in high labor intensity. Some extruders have a structure integrating extrusion and transmission, which needs to be manufactured from the initial design of the extruder, and the transmission method is belt transmission, occupying a large space and having a complex working method. With the development of intelligent manufacturing, the MES (Manufacturing Execution System) system and the AGV (Automated Guided Vehicle) transportation system have been widely used in various types of automated production lines. AGVs are characterized by wheeled movement and have advantages such as fast movement, high work efficiency, simple structure, strong controllability, and good safety compared with walking, crawling, or other non-wheeled mobile robots. Compared with other commonly used equipment in material transportation, the activity area of AGVs does not require fixed devices such as tracks and support frames to be laid, and is not restricted by the site, road, and space. Therefore, it can most fully reflect its automation and flexibility in automated transfer, realizing efficient, economical, and flexible unmanned production. However, AGV cars can only complete the distance transfer of materials and cannot achieve loading and unloading. For example, when an existing extruder is combined with an AGV car to connect and transfer rubber materials, since there is no automatic docking loading and unloading mechanism on the extruder to cooperate with the AGV car, it is necessary to manually carry the rubber materials onto the table of the AGV car every time the AGV picks up and delivers the rubber materials, and seamless connection of the rubber materials from discharging, connection to transfer cannot be formed. Summary of the Invention

[0003] The connecting and discharging extruder provided by the present invention adds a connecting function that automatically docks with an AVG car on the extruder, improves the efficiency of rubber material transfer, reduces the manual labor intensity, ensures the safety of rubber material connection, and only needs to install a connecting and discharging rack on the existing extruder to form a connecting and discharging extruder, without changing the internal structure of the extruder, being easy to install and having a low cost and high practicability. The present invention also provides an extruder discharging connection system and method.

[0020] The following combines Figures 1 to 4 to make a detailed description of the embodiments of the present invention.

[0021] The feeding-out connection extruder includes an extruder 1 and a feeding-out rack 2 installed on the extruder. It is characterized in that: the feeding-out rack 2 includes a material receiving roller bed 3 installed at the discharge port of the extruder 1 to receive the rubber material, and an automatic pusher rod 4 controlled by the upper system of the extruder. The automatic pusher rod 4 moves on the material receiving roller bed 3 under the control of the upper system of the extruder to push the rubber material on the material receiving roller bed 3 outwards.

[0022] For the above-mentioned feeding-out connection extruder, a feeding-out rack 2 is installed on the extruder 1. The material receiving roller bed 3 in the feeding-out rack 2 is installed at the discharge port of the extruder 1 to receive the rubber material extruded from the extruder. The automatic pusher rod 4 is controlled by the upper system of the extruder to push the rubber material on the material receiving roller bed 3 outwards. The feeding-out connection extruder is combined with the AGV cart. The feeding-out rack 2 receives the discharge of the extruder and automatically pushes the discharge onto the AGV cart, realizing seamless connection of the rubber material from the extruder 1 to the AGV cart. A new connection function for automatic docking with the AGV cart is added to the extruder, improving the efficiency of rubber material transfer, reducing the labor intensity of workers. The automatic pusher rod 4 is controlled by the upper system of the extruder and only pushes out the rubber material after the AGV cart cooperates with the material receiving roller bed, ensuring the safety of rubber material connection. Only by installing a feeding-out rack on the existing extruder can a feeding-out connection extruder be formed, without changing the internal structure of the extruder, which is convenient for installation and has a low cost and high practicability.

[0023] Among them, the material receiving roller bed 3 is a roller bed formed by arranging multiple unpowered rollers side by side. The rear end of the material receiving roller bed 3 is hinged to the extruder 1. The material receiving roller bed 3 is supported by a cylinder 5 installed on the extruder 1 and controlled by the upper system of the extruder. The material receiving roller bed 3 is supported to be horizontal as the cylinder 5 extends. The material receiving roller bed 3 is in an open state when the cylinder 5 extends. At this time, it can receive the rubber material at the discharge port of the extruder. When the extruder does not discharge material, the cylinder 5 retracts to lower and retract the material receiving roller bed 5, reducing the occupied space of the extruder in the non-use case. In the case of needing feeding-out connection, the material receiving roller bed 5 is automatically opened to the horizontal under the control of the upper system of the extruder.

[0024] Among them, the automatic pusher rod 4 includes an electric push rod 6 controlled by the upper system of the extruder and a pusher plate 7 that can push the rubber material to move on the receiving roller bed. The pusher plate 7 is fixed to the front end of the electric push rod 6 and is vertically arranged at the rear end of the receiving roller bed 3, and moves on the receiving roller bed 3 along with the movement of the electric push rod 8. The initial position of the pusher plate 7 is set at the rear end of the receiving roller bed 3. When it is necessary to push out the rubber material on the receiving roller bed 3, the electric push rod 8 drives the pusher plate 7 to move on the receiving roller bed 3 to push out the rubber material. After pushing out, the electric push rod 8 drives the pusher 7 to move back to the initial position.

[0025] Among them, the electric push rod 6 includes a linear guide rail 8 with a servo motor and a push rod 9 fixedly arranged in parallel on the linear guide rail 8. The pusher plate 7 is fixed to the front end of the push rod 9. The combination of the servo motor and the linear guide rail can ensure the stability and efficiency of the pushing process when the pushing distance exceeds 1 meter, and is convenient for adjusting the pushing speed and displacement to adapt to different pushing requirements.

[0026] Among them, a weighing sensor that can weigh the rubber material and is connected to the upper system of the extruder is installed on the receiving roller bed 3, and a weighing display 10 for displaying the sensing value of the weighing sensor is installed on the side of the extruder 1. When the rubber material is extruded from the discharge port of the extruder and falls onto the receiving roller bed 3, the weighing sensor senses the weight of the rubber material, and the weighing display 10 displays the weight of the rubber material in real time. When the weight of the rubber material meets the preset requirements, the upper system of the extruder controls the extruder 1 to stop discharging. The weighing sensor and the weighing display 10 can monitor the discharging weight of the extruder in real time, forming a monitoring of the discharging of the extruder, and can stop the operation of the extruder in time when a fault occurs.

[0027] Among them, it also includes a cutter 11 installed at the discharge port of the extruder for cutting the rubber material, and the action of the cutter 11 is controlled by the upper system of the extruder. When the weight of the rubber material on the receiving roller bed 3 meets the preset requirements, the upper system of the extruder controls the cutter 11 to cut the rubber material and stop the discharging of the extruder to prevent the rubber material from sticking continuously.

[0028] The present invention also protects an extruder discharge connection system, which is characterized in that: it includes the above-mentioned connection and discharge extruder and an AGV cart 12. The automatic pusher rod 4 runs with the AGV cart 12 to be docked with the pusher plate to push the rubber material on the receiving roller bed onto the AGV cart 12. By matching the above-mentioned connection and discharge extruder with the AGV cart, the extruder's discharge is received through the connection and discharge rack 2 and automatically pushed onto the AGV cart, realizing seamless connection of the rubber material from the extruder 1 to the AGV cart, improving the efficiency of rubber material transfer, and reducing the labor intensity of workers.

[0029] The AGV trolley 12 includes a shelf 13 and an AGV module 14 that carries the shelf 13 and moves. The top of the shelf 13 is a roller bed surface formed by multiple immobile rollers arranged side by side. The AGV module 14 carries the shelf 13 and moves. The top of the shelf 13 is a roller bed surface that is adapted to the material receiving roller bed 3, so that the rubber material can be pushed from the material receiving roller bed 3 to the roller bed surface of the shelf 13 by the automatic push rod 4. When the AGV trolley is docked with the docking and discharging extruder, the automatic push rod 4 pushes the rubber material from the material receiving mixing bed 3 to the roller bed surface of the AGV trolley, ensuring the reliability of the rubber material docking.

[0030] The present invention also protects an extruder discharge connection method, which uses the above-mentioned extruder discharge connection system to perform discharge connection rotation, and is characterized in that it includes the following steps: First, the extruder host system, the AGV dispatching system, the AGV and the MES system are interconnected through a network. Then: the MES system sends the discharge information to the extruder upper system, the MES system sends the rubber material connection position information to the AGV scheduling system, and the AGV scheduling system sends the scheduling information to the AGV car; Next, the upper system of the extruder controls the discharging extruder to discharge the material to the receiving roller bed, and the AGV runs to the discharging extruder according to the scheduling information; After that, the AGV trolley docks with the receiving roller bed of the material extruder and sends information to the extruder host system. The extruder host system controls the automatic push plate to push the rubber material on the receiving roller bed to the AGV trolley. Finally, the AVG material transport cart transfers the rubber to the delivery location according to the adjustment information, completing the docking and transportation of the rubber.

[0031] The method described above interconnects the extruder host system, the AGV dispatching system of the AGV trolley, the AGV trolley and the MES system, controls the operation of the extruder and the AGV trolley through information transmission, forms a seamless connection of the rubber from discharging, docking to transportation, improves the efficiency of rubber transportation, reduces manual labor intensity, and can intelligently dispatch the AGV trolley according to the operating status of multiple docking discharging extruders, forms a seamless discharging connection of multiple docking discharging extruders to one AGV trolley, and forms intelligent rubber docking and transportation.

[0032] Among them, "the upper system of the extruder controls the discharge of the extruder to the receiving roller bed" specifically refers to: The upper system of the extruder first controls the cylinder to extend to support the material receiving roller bed 3 to the horizontal, then controls the extruder 1 to discharge materials onto the material receiving roller bed 3, and the weighing sensor weighs the rubber material on the material receiving roller bed. When the weight of the rubber material reaches the discharging requirement, the upper system of the extruder controls the extruder 1 to stop discharging and controls the cutter 10 to cut the rubber material. After the upper system of the extruder first controls the material receiving roller bed 3 to open and then discharges, weighs, and cuts the rubber material, the reliability of the rubber material connection is ensured.
