Description

Technical Field

[0001] This utility model relates to the field of finished explosive boxes, and in particular to a finished explosive box conveying and buffering device. Background Technology

[0002] The loading of finished explosives often employs a tracked loading and unloading robot system. This system consists of a tracked system, a multi-jointed robot, and a buffer telescopic belt. During loading, the tracked system provides power, propelling the robot and the telescopic buffer belt into the truck bed. The robot then picks up the finished explosive boxes from the buffer belt and places them into the truck bed. The buffer telescopic belt moves along with the tracked system. During the transport of the finished explosive boxes, there is a height difference between the fixed belt and the telescopic buffer belt. This height difference is addressed by a non-powered transition roller. Therefore, during this process, the finished boxes are continuously accelerated by gravity and eventually impact the telescopic belt. Since the finished boxes weigh up to 25 kg and the contact area is small during impact, the significant impact force easily leads to structural damage such as cracking or breakage of the boxes.

[0003] Chinese Patent CN107879135A discloses a continuous feeding automatic loading system. Specifically, it discloses a forward output roller line with an inclined arrangement at one end of a forward and reverse belt conveyor. Due to the inclined arrangement of the forward output roller line, the finished explosive box continuously accelerates and eventually impacts the telescopic belt, thereby damaging the finished explosive box. Therefore, there is an urgent need for a finished explosive box conveying buffer device that can reduce the descent speed of the finished explosive on the forward output roller line, thereby avoiding damage to the finished explosive box.

[0030] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0031] Please refer to Figures 1 to 2 A finished product box conveying buffer device, comprising:

[0032] First conveyor belt 1;

[0033] The inclined transition roller 2 has its starting end located at the end of the first conveyor belt 1;

[0034] Gantry 3 is connected to the side of the transition roller 2 near the end.

[0035] The buffer device body 4 includes a rotating shaft 41, a first cylinder 42, a connecting rod 43, and a fixing block 44. The fixing block 44 is inclinedly connected to one side of the gantry 3. The cylinder body of the first cylinder 42 is connected to the fixing block 44. The rotating shaft 41 is rotatably connected between the gantry 3. One end of the rotating shaft 41 extends to one side of the gantry 3. The rotating shaft 41 is pivotally connected to the piston rod of the first cylinder 42 through the connecting rod 43. The axis of the pivot is parallel to the axis of the rotating shaft 41.

[0036] Baffle 5 is connected to the upper part of the rotating shaft 41;

[0037] Photoelectric switch 6 is connected to the side of transition roller 2 near the beginning.

[0038] The first cylinder 42 drives the baffle 5 to switch between the first and second states;

[0039] In the first state, the baffle 5 is closed and perpendicular to the surface of the first conveyor belt 1;

[0040] In the second state, the baffle 5 is open and parallel to the surface of the first conveyor belt 1.

[0041] In the above embodiments, when the finished explosive box is conveyed from the beginning to the end of the first conveyor belt 1, it falls onto the transition roller 2. The photoelectric switch 6 senses the finished explosive box and transmits a signal to the controller. The controller controls the first cylinder 42 to switch the baffle 5 from the second state to the first state, thereby blocking the finished explosive box from falling. After a period of time, the first cylinder 42 drives the baffle 5 to switch from the first state to the second state, the baffle 5 opens, and the finished explosive box continues to fall by gravity, thereby reducing the acceleration of the finished explosive box at the end and realizing staged falling to reduce the impact force at the end. Compared with the prior art, this device is simple to install, has low cost, strong versatility, can reduce the falling speed of the finished explosive box on the forward output roller line, can greatly reduce carton damage, save production costs, and improve product quality.

[0042] As an alternative implementation, the baffle 5 is welded to the rotating shaft 41.

[0043] As an optional implementation, the side of the baffle 5 near the beginning of the transition roller 2 is provided with a buffer layer 51.

[0044] In the above embodiments, the buffer layer 51 is a sponge layer, which can reduce the damage when the finished explosive box touches the baffle 5.

[0045] As an optional implementation, there are two buffer device bodies 4, which are symmetrically arranged on both sides of the gantry 3.

[0046] In the above embodiments, the stability of the baffle 5 rotation is further enhanced.

[0047] As an optional implementation, the end of the first conveyor belt 1 is also provided with a blocking device 7. The blocking device 7 includes a second cylinder 72 and a baffle 71. The baffle 71 is located between two adjacent conveyor rollers at the end of the first conveyor belt 1. The baffle 71 is parallel to the axial direction of the rotating shaft 41. The piston rod of the second cylinder 72 is connected to the baffle 5. The axial direction of the second cylinder 72 is vertical.

[0048] In the above embodiments, by setting the baffle 71, it is possible to prevent two finished explosive boxes from falling onto the transition roller 2 at the same time. When the first cylinder 42 drives the baffle 5 to switch to the second state of opening, the second cylinder 72 drives the baffle 5 to extend. The baffle 5 is higher than the surface of the first conveyor belt 1, thereby blocking the subsequent finished explosive boxes.

[0049] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent modifications made based on the content of this utility model specification and drawings, or direct or indirect applications in related technical fields, are similarly included within the patent protection scope of this utility model.
