Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, and in particular to an accumulation and release type conveying chain conveying device. Background Art

[0002] The development process of flexible production lines from single-vehicle single-line to multiple-vehicle co-line. In the production and assembly process of automobiles, multi-directional conveyor chains are needed to transport automobile parts to designated locations. In factory workshops, these items can not only be transported conveniently and accurately, but also save manpower and improve production efficiency.

[0003] The Chinese patent application number 201320800318.9 discloses a stacking type conveyor line device, including a head wheel, a tail wheel and a conveying trolley, wherein the head wheel and the tail wheel respectively include a bending disc arranged around the main shaft, and the outer periphery of the bending disc is provided with a bending disc connecting block, and the bending disc telescopic pin passes through the bending disc connecting block and extends from its outer surface; the bottom side of the wheel cover is connected to the auxiliary bending mechanism buffer block through the auxiliary bending mechanism welding block; the conveying trolley includes a bending contact block and an auxiliary roller. The conveying line device also includes a stop mechanism with a connecting shaft, and the connecting shaft is provided with an impact block that can move up and down, which cooperates with a stop baffle provided on the conveying trolley. The conveying line device also includes a tensioning mechanism, which has a movable adjustment sprocket. The bending mechanism can clamp the trolley to ensure that the trolley can turn smoothly. The stopping mechanism can stop the conveying trolley at a specific position and prevent it from moving backwards. The tensioning mechanism can tension the conveying chain to ensure the smooth operation of the conveyor line. However, the conveying device still has some shortcomings. The device uses a single chain for conveying during the conveying process, and the conveying stability is poor. At the same time, the conveying load is small. At the same time, the conveying device cannot adjust the conveying width and cannot stably convey goods of different widths, resulting in poor applicability. At the same time, the conveying device cannot limit and fix the goods on the pallet during the conveying process, which can easily cause the goods to slip and cause damage to the goods. At the same time, during the conveying process, since the goods need to be transported to the next workstation, when the conveying device stops conveying, the goods will move due to inertia, which will produce a certain inertial impact force on the pallet. Long-term impact force will cause damage to the conveying device. Summary of the invention

[0022] (1) The material discharging mechanism is installed on the transmission tray plate, and the positions of the clamping block and the first mounting block are adjusted according to the size of the material. When the material is placed in the material discharging frame on the material discharging mechanism, the weight of the material drives the material discharging frame to move downward, and then the material discharging frame drives the support column to move downward, and then drives the ball bearings on the clamping block to automatically clamp and fix the two sides of the material. At the same time, the downward movement of the material discharging frame drives the transmission rod to move, thereby driving the first buffer clamping roller and the second buffer clamping roller 27 to move to clamp and fix the other two sides of the material, so that the conveying device can automatically limit and fix goods of different sizes, thereby improving the stability of cargo transportation.

[0023] (2) When the conveying device stops after conveying the material to the specified position, the material continues to move forward due to the inertia force, which will drive the discharge mechanism and the transmission tray plate to move forward. At this time, the conveying device will have a large impact force, causing damage to the conveying device. At this time, the goods slide on the discharge roller due to inertia, and then slide to the first buffer clamping roller and the second buffer clamping roller. At this time, the goods are lifted, and the inertia force is converted into the gravitational potential energy of the goods, thereby buffering the inertia of the goods, reducing the impact damage to the conveying device caused by the inertia force of the goods, and increasing the service life of the conveying device.

[0024] (3) The two mounting frames are driven to move by the adjustment mechanism, and the spline shaft on the mounting shaft slides in the spline groove, and then the connecting plate on the transmission tray plate slides in the connecting groove, so as to adjust the width of the two transmission tray plates, thereby improving the applicability of the conveying device, thereby expanding the conveying width of the conveying device, and at the same time, the transmission is carried out through two chains and two second transmission gears on the transmission tray plate, which greatly improves the stability of the conveying device, so that the conveying device can be automatically adjusted, and the conveying device can stably transport goods of different sizes. (4) By inserting the connecting block on the discharge mechanism into the fixing groove on the fixing block, and then portable fixing the connecting block in the fixing groove on the fixing block by the clamping fixing mechanism, the portable installation of the discharge mechanism is realized. When replacing different discharge mechanisms, the ring can also be removed in a portable manner, thereby realizing the portable replacement of the discharge mechanism, which is convenient for users.

At the same time, during the goods transportation process, when the goods are transported to the designated position After the conveying device is put into operation, the conveying device begins to suspend conveying.
