Technical Field

[0001] The utility model belongs to the technical field of mechanical equipment, in particular to a full stack detection device. Background Art

[0002] After powder materials such as flour and cement are canned, the canned materials need to be stacked on the conveyor belt. After full stacking, the conveyor belt will transport them to the designated position and then unload them. At present, photoelectric sensors are usually used to stop the stack at the designated position when full stacking is conveyed. However, photoelectric sensors are sensitive to changes in working conditions. For example, dust falling on the emitting or receiving surface of the photoelectric sensor will affect the accuracy of the sensor; or large changes in ambient light will also affect the photoelectric sensor, resulting in collisions, loose stacks, etc. Therefore, it is urgent to design a full stack detection device that can enable the equipment to better adapt to the environment and achieve reliable and accurate positioning when full stacking is achieved. Summary of the invention

DETAILED DESCRIPTION

[0019] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-Figure 5 As shown, a full stack in-place detection device comprises a floating roller 1, one side of the floating roller 1 is rotatably connected to a fixed block 3 via a fisheye bearing 2, and the other side of the floating roller 1 is fixedly connected to an in-place detection mechanism, the in-place detection mechanism comprises a first vertical plate 4 bolted to the floating roller 1, an induction horizontal plate 5 perpendicular to and integrally connected to the lower end of the first vertical plate 4, a lower horizontal plate 6 located below the induction horizontal plate 5 and arranged parallel to the induction horizontal plate 5, and a second vertical plate 7 and a third vertical plate 8 respectively perpendicular to and integrally arranged at both ends of the lower horizontal plate 6, the second vertical plate 7 is adjacent to and parallel to the first vertical plate 4, the third vertical plate 8 is located on one side of the induction horizontal plate 5, a proximity switch 9 is fixedly arranged on the third vertical plate 8, an upper limit structure 10 for limiting the position of the induction horizontal plate 5 is arranged between the induction horizontal plate 5 and the lower horizontal plate 6, and a lower limit structure 11 for limiting the position of the induction horizontal plate 5 is arranged on the lower horizontal plate 6.

[0021] Specifically, the floating roller 1 can be raised or lowered by changing the load caused by a full stack of materials. When floating up and down, one side of the floating roller 1 is realized by the fisheye bearing 2 structure, and the other side is realized by the in-place detection mechanism. The upper limit structure 10 and the lower limit structure 11 limit the range of movement of the sensing cross plate 5 in the in-place detection mechanism. When the full stack of materials presses the floating roller 1 downward, the sensing cross plate 5 descends to the position of the lower limit structure 11, and the proximity switch 9 detects the sensing cross plate 5. When the full stack of materials is transported away, the floating roller 1 rises and returns to its initial position. At the same time, the upper limit structure 10 drives the sensing cross plate 5 to return to its initial position.

[0022] Furthermore, baffles 12 are provided on both sides of the second vertical plate 7 , and guide grooves 13 are formed between the baffles 12 and the second vertical plate 7 . A plurality of ball bearings 14 are bolted to the first vertical plate 4 , and the ball bearings 14 are located in the guide grooves 13 and matched with the guide grooves 13 .

[0023] Specifically, in order to make the floating drum 1 move up and down more stably and smoothly, a guide groove 13 is formed by the second vertical plate 7 and the baffle 12 to provide a guide for the up and down movement of the floating drum 1. At the same time, a ball bearing 14 is arranged in the guide groove 13 to make the floating drum 1 move up and down more smoothly. The number of the ball bearings 14 is not less than 2.

[0024] Furthermore, the upper limit structure 10 includes an upper limit bolt 15 that penetrates the sensing cross plate 5 and the lower cross plate 6, the lower end of the upper limit bolt 15 is connected to a limit nut 16, and a compression spring 17 is sleeved on the upper limit bolt 15 between the sensing cross plate 5 and the lower cross plate 6; the lower limit structure 11 includes a lower limit bolt 18 that is fixed on the lower cross plate 6, and the end of the lower limit bolt 18 close to the sensing cross plate 5 is at the same height as the proximity switch 9.

[0025] Specifically, when the floating roller 1 is pressed down by a full stack of materials, it drives the first vertical plate 4 and the sensing cross plate 5 to move downward, and the compression spring 17 is further compressed until the sensing cross plate 5 contacts and stops with the lower limit bolt 18. At this time, the proximity switch 9 detects the sensing cross plate 5. When the full stack of materials is transported away, the compression spring 17 rebounds, driving the sensing cross plate 5, the first vertical plate 4 and the floating roller 1 upward until the lower cross plate 6 contacts and stops with the limit nut 16.

[0026] Furthermore, the floating drum 1 includes an inner fixed shaft 19 and an outer cylinder 20 rotatably connected to the inner fixed shaft 19 by a bearing, and the fixing block 3 and the first vertical plate 4 are respectively fixed to two ends of the inner fixed shaft 19 with bolts.

[0027] Specifically, the floating drum 1 is provided with a bearing, which can push the outer drum 20 to rotate when a full stack of materials arrives or passes by, so that the stack can pass smoothly without causing any resistance to it.

[0028] like Figure 6-Figure 7As shown, the working process of the utility model is as follows: first, the floating roller 1 is fixedly mounted on the frame 22 of the roller conveyor 21 through the fixing block 3 and the second vertical plate 7, and the initial position of the floating roller 1 is set to be 10 mm to 15 mm higher than the conveying plane of the roller conveyor 21. When a full stack of materials reaches the floating roller 1, the floating roller 1 is pressed down by the gravity of the full stack, and at the same time, the first vertical plate 4 and the induction cross plate 5 are driven to move downward, and the compression spring 17 is further compressed until the induction cross plate 5 contacts the lower limit bolt 18 and stops. At this time, the proximity switch 9 detects the induction cross plate 5, and the proximity switch 9 outputs a signal to pause the roller conveyor 21. When the full stack leaves the position, the compression spring 17 rebounds, driving the inductive cross plate 5, the first vertical plate 4 and the floating roller 1 upwards, until the lower cross plate 6 contacts the limit nut 16 and stops, and the floating roller 1 returns to its initial position, and the inductive cross plate 5 leaves the detection range of the proximity switch 9. The utility model has a stable and reliable structure, is less affected by changes in the working environment, has sensitive detection, and realizes the rising and falling actions of the floating roller 1 through the change of the load applied to the floating roller 1 by the full stack, and performs signal feedback through the proximity switch 9, thereby realizing reliable and accurate positioning of the full stack, solving the problem of inaccurate stop position or inability to stop of the full stack, and greatly improving the stability of the equipment.

[0029] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
