[0002] In order to reduce production costs and improve production efficiency, fasteners are produced on automated production lines. However, the height of the material drop outlet from the production line to the material box is too high. During the material feeding process, the products are prone to collisions and scrapes against the inner wall of the material box, which can lead to product damage. Utility Model Content

[0014] like Figure 1 As shown, a fastener bin tipping mechanism includes a base frame 1, on which a bin tipping bucket 2, a tipping bucket tipping mechanism 3, and a tipping bucket control system are integrated.

[0015] like Figure 2 As shown, the structure of the material bin tipping hopper 2 further includes a bottom plate 21, a limiting plate 22, a left side plate 23, and a right side plate 24. The bottom plate is supported on the base frame, and the rear end of the bottom plate is connected to the front end of the limiting plate as a whole. The limiting plate is inclined, and the left sides of the bottom plate and the limiting plate are connected as a whole through the left side plate, and the right sides of the bottom plate and the limiting plate are connected as a whole through the right side plate. This structure is simple, has low manufacturing cost, is suitable for material bins of various sizes, and has high versatility.

[0016] like Figure 3 and Figure 4 As shown, the structure of the tipping mechanism 3 further includes: a bearing support 31, a rotating shaft 32, a tipping bracket 33, a hydraulic cylinder 34, and a hydraulic station 35. The rotating shaft is fixed to the base frame via the bearing support. One end of the tipping bracket is fixedly connected to the rotating shaft, and the other end of the tipping bracket is fixedly connected to the upper back of the limiting plate. The hydraulic cylinder is located in the lower cavity of the tipping bracket, and the working end of the hydraulic cylinder is hinged to the lower back of the limiting plate. The cylinder body of the hydraulic cylinder is hinged to the base frame, and the hydraulic station is fixed to the base frame. This structure is simple, which helps to reduce the number of parts and reduce weight, and provides good working stability.

[0017] like Figure 3 and Figure 4As shown, the structure of the tipping bucket control system further includes an upper limit sensor 41, a lower limit sensor 42, an angle sensor 43, and a weighing sensor 44. The upper limit sensor is fixed on the top of the bearing support of the tipping bucket mechanism, and the lower limit sensor is fixed on the base frame. The upper limit sensor and the lower limit sensor are used to control the start / stop of the tipping bucket mechanism. The angle sensor is fixed on the rotating shaft of the tipping bucket mechanism and is used to control the rotation angle of the rotating shaft and start / stop the hydraulic oil station in the tipping bucket mechanism, thereby controlling the tipping angle of the hopper. The weighing sensor is fixed on the tipping bucket mechanism and is used to measure the weight of the hopper and start / stop the hydraulic oil station in the tipping bucket mechanism.

[0018] Furthermore, the upper limit sensor and lower limit sensor are contact limit sensors, the angle sensor is an electromechanical angle sensor, and the load cell is a hydraulic load cell; a pin seat is provided on the back of the lower end of the limit plate, the pin seat 45 is connected to the load cell through a pivot pin 46, and the load cell is connected to the piston rod of the hydraulic cylinder.

[0019] like Figure 2 As shown, a rubber buffer layer 5 is further provided on the support surface of the limiting plate; in order to avoid abnormal noise and damage caused by collision, the rubber buffer layer buffers the tipping of the material box.

[0020] like Figure 5 As shown, during operation, the material box 6 is placed on the base plate. The PLC controller starts the hydraulic oil station to supply hydraulic oil to the hydraulic cylinder, thereby pushing the material box tipper to rotate. When the material box tipper triggers the upper limit sensor, the hydraulic oil station stops working. At this time, the material box is tilted at a small angle, and the distance from the material drop port of the production line 7 to the side plate of the material box is small, so there will be no damage to the products after they fall. When the products in the material box reach a certain quantity, the weighing sensor sends a signal to the PLC controller, which starts the hydraulic cylinder to pull the material box tipper back to a small angle. When it returns to the preset position, the angle sensor sends a signal to the PLC controller, and the hydraulic cylinder stops working. The products in the material box are displaced by flipping, making room for subsequent products to fall. When the weighing sensor senses the weight limit value, it sends a signal to the PLC controller, the production line stops conveying, and the hydraulic oil is started to continue pulling the material box tipper back to its original position. When the material box tipper triggers the lower limit sensor, the hydraulic oil station stops working. At this time, the base plate is supported on the base frame, and the material boxes in the tipper can be transferred.
