Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of damage detection, in particular to a production line plate-shaped object damage detection structure. Background Art
[0002] The production line refers to the route of a series of activities experienced in the production process of a product. It includes all the steps from the entry of raw materials into the production site, through processing, transportation, assembly and inspection, and finally the output of finished products. The basic principle of the production line is to decompose the repetitive links in the production process into functions, carry out them in sequence in time, and overlap and parallel in space, so that different sub-processes can be carried out at the same time, thereby improving production efficiency. Therefore, if any process in the production line stops, it will cause all subsequent processes to wait, not to mention that the entire production line stops production. If the production line is easily stopped, it will seriously affect the production efficiency of the factory.
[0003] For example, in a tile production line, the method for detecting whether a tile is broken during the production process is to use an optical sensor such as an edge sensor or a reference sensor to turn on, and after determining the turn-on time or the number of pulses, compare it with a predetermined reference value to determine whether the tile is broken; that is, multiple sensors are set above or below the moving position of the tile to detect the integrity of the edge of the tile, so as to deduce whether the tile is broken from whether the four edges of the tile are broken; when it is judged to be broken, the movement is stopped and an alarm is issued.
[0004] The above method requires the use of multiple or more sensors for detecting the edge of tiles, and they also need to be set up on the production line to detect the tiles passing by, and then the main controller processes and judges the multiple or more sensor signals to get the final result; whether it is the complexity of the setting relationship of multiple or more sensors, or the installation of sensor accessories on the production line, the cost is very high and complicated, the installation time is long, and the maintenance is difficult; and the main controller also needs to comprehensively judge and process the multi-sensor signals, and the judgment and processing time is long; more importantly, the handling method of broken tiles also seriously affects the production efficiency of the production line; so this method cannot meet the current production line The high-efficiency production needs.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present invention can be understood according to specific circumstances.
[0030] Combine the following Figures 1 to 3 , describing a production line plate-like object damage detection structure according to an embodiment of the utility model.
[0031] A production line plate-like object damage detection structure comprises a rightward conveying mechanism 1, a frontward conveying mechanism 2, a forward conveying mechanism 3, a backward conveying mechanism 4 and a main controller; the right end of the rightward conveying mechanism 1 is connected to the left end of the frontward conveying mechanism 2, the rear end of the frontward conveying mechanism 2 is connected to the front end of the backward conveying mechanism 4, and the front end of the frontward conveying mechanism 2 is connected to the rear end of the forward conveying mechanism 3;
[0032] A damage detection electric eye 11 is provided at the upper center of the right conveying mechanism 1, and the main controller is electrically connected to the damage detection electric eye 11 and the front and rear conveying structures 2 respectively;
[0033] The main controller is used to detect the passing time A of the plate-like object through the damage detection electric eye 11; when the passing time A exceeds the preset time B, the front and rear conveying mechanisms 2 are controlled to convey forward.
[0034] The utility model proposes a preferred embodiment of a production line plate-like object damage detection structure, such as Figure 1 As shown, in the case where the plate-like object is not damaged, the plate-like object is transported to the right by the right conveying mechanism 1, and after being transferred to the front-rear conveying mechanism 2, it is transported backward by the front-rear conveying mechanism 2, and transferred to the rear conveying mechanism 4, and finally transferred to the subsequent process by the rear conveying mechanism 4. If the plate-like object is damaged, the plate-like object will be detected and scanned by the damage detection electric eye 11 during the process of the right conveying mechanism 1 transferring the plate-like object to the front-rear conveying mechanism 2, and the passing time A of the plate-like object passing through the damage detection electric eye 11 is known; because the passing time A is basically constant when the plate-like object is intact, this basically constant time is used as the preset time B. When the plate-like object is damaged, due to the shaking of the conveying mechanism during the conveying and transferring process, the damaged parts of the damaged plate-like object will gradually separate due to the friction, etc., which leads to the extension of the passing time A. Therefore, by comparing the passing time A with the preset time B, it can be known whether the conveyed plate-like object is damaged. When the plate-like object is confirmed to be damaged, the main controller controls the front and rear conveying mechanism 2 to change from backward conveying to forward conveying, and removes the damaged plate-like object from the production line without transferring it to the subsequent process; after removal, the main controller changes the front and rear conveying mechanism 2 back to backward conveying, and waits for the next plate-like object to be transferred. In this way, it is possible to identify whether the plate-like object on the production line is damaged with the least detection equipment and the simplest algorithm, and remove it from the production line in time, which is convenient to install, simple to maintain, low in cost, short in judgment and processing time, and does not affect the normal operation of the production line.
[0035] Furthermore, the damage detection electric eye 11 is used to generate a detection signal when a plate-like object is detected, otherwise it generates a signal to be tested;
[0036] The main controller is used to start timing to a preset time B when receiving a detection signal, and generate a holding signal after timing to the preset time B; when the holding signal and the detection signal exist at the same time, the front and rear conveying mechanisms 2 are controlled to convey forward.
[0037] In this embodiment, the main controller can use a controller similar to a PLC, and the signal relationship between the main controller and the damage detection electric eye 11 is: when the damage detection electric eye 11 detects a plate-like object, it will generate a detection signal transmitted to the main controller, triggering the timer programmed by the main controller to start timing to the preset time B; when timing to the preset time B, keep this time without resetting, and judge whether the damage detection electric eye 11 still detects the plate-like object (that is, the detection signal) at this time; if the plate-like object is still detected, it proves that the plate-like object passing time A is longer than the original preset time B, which means that the plate-like object has been damaged, resulting in the separation of the damaged parts, resulting in the lengthening of the passing time A, so at this time the main controller can control the front and rear conveying mechanisms 2 to change to forward transmission, and remove the damaged plate-like objects from the production line, thereby realizing the judgment and processing process.
[0038] Furthermore, the damage detection electric eye 11 is arranged at the right end of the rightward conveying mechanism 1 .
[0039] In this embodiment, because the damage detection electric eye 11 will take measures to process the plate-like object after detecting the plate-like object, it is necessary to ensure that the plate-like object completely enters the conveying part of the front-rear conveying mechanism 2 after being detected and scanned by the damage detection electric eye 11. Therefore, the damage detection electric eye 1 is set at the right end of the right conveying mechanism 1. When the leftmost end of the plate-like object is detected, it completely enters the front-rear conveying mechanism 2 and can be processed by the front-rear conveying mechanism 2 according to the judgment.
[0040] Further, the front and rear conveying mechanism 2 is provided with an ascending limit electric eye 21 and a descending limit electric eye 22; the ascending limit electric eye 21 and the descending limit electric eye 22 are mounted on the right side of the front and rear conveying mechanism 2, the ascending limit electric eye 21 and the top of the conveying part of the forward conveying mechanism 3 or the backward conveying mechanism 4 are in the same horizontal plane, the descending limit electric eye 22 and the top of the conveying part of the forward conveying mechanism 3 or the backward conveying mechanism 4 are in the same horizontal plane, and the front and rear conveying mechanism 2 can rise or fall between the ascending limit electric eye 21 and the descending limit electric eye 22;
[0041] The main controller is electrically connected to the rising limit electric eye 21 and the falling limit electric eye 22 respectively;
[0042] The main controller is also used to control the front and rear conveying mechanisms 2 to rise to the rising limit electric eye 21 or to fall to the falling limit electric eye 22 when the holding signal and the detection signal exist at the same time.
[0043] In this embodiment, Figure 2As shown, after the plate-like object enters the front-and-rear conveying mechanism 2, it needs to be transferred by the front-and-rear conveying mechanism 2 to the forward conveying mechanism 4 (subsequent process) or the backward conveying mechanism 3 (rejection), and the conveying parts of the forward conveying mechanism 4 and the backward conveying mechanism 3 are not necessarily in the same horizontal plane. Therefore, when the front-and-rear conveying mechanism 2 conveys the plate-like object to the corresponding conveying mechanism according to the judgment result, the conveying part of the front-and-rear conveying mechanism 2 needs to be raised and lowered to the same horizontal plane as the conveying part of the corresponding conveying mechanism. To this end, an upward limit electric eye 21 and a downward limit electric eye 22 are set on the right side of the front-and-rear conveying mechanism 2 to limit the lifting degree of the front-and-rear conveying mechanism 2.
[0044] Furthermore, the top ends of the conveying parts of the rightward conveying mechanism 1 and the backward conveying mechanism 4 are in the same horizontal plane.
[0045] In this embodiment, because the right conveying mechanism 1 and the rear conveying mechanism 4 are both conveying devices for plate-like objects in normal state, the top ends of the conveying parts of the right conveying mechanism 1 and the rear conveying mechanism 4 are set to be in the same horizontal plane, which can ensure that the production line segment formed with the front and rear conveying mechanisms 2 can normally transport the plate-like objects in normal state.
[0046] Furthermore, the forward conveying mechanism 3 includes a horizontal conveying part 31, a slope conveying part 32 and a damaged collection trough 33; the rear end of the horizontal conveying part 31 is transferred and connected to the front end of the front and rear conveying mechanism 2, the front end of the horizontal conveying part 31 is transferred and connected to the upper end of the slope conveying part 32, and the lower end of the slope conveying part 32 is arranged in the damaged collection trough 33.
[0047] In this embodiment, Figure 3 As shown, the forward conveying mechanism 3 functions to receive and collect the rejected damaged plate-like objects for subsequent centralized processing; therefore, the forward conveying mechanism 3 is composed of a horizontal conveying part 31, a slope conveying part 32 and a damaged collection trough 33, wherein the horizontal conveying part 31 is in the same horizontal plane as the conveying parts of the front and rear conveying mechanisms 2, receives the damaged plate-like objects transferred from the front and rear conveying mechanisms 2, and then is guided and conveyed to the damaged collection trough 33 by the slope conveying part 32.
[0048] Furthermore, both the rightward conveying mechanism 1 and the backward conveying mechanism 4 are one-way conveyor belt devices.
[0049] In this embodiment, when the front and rear conveying mechanism 2 conveys backward, the front and rear conveying mechanism 2, the right conveying mechanism 1 and the backward conveying mechanism 4 form a one-way conveying line to convey the plate-like object to the subsequent process, so the right conveying mechanism 1 and the backward conveying mechanism 4 are preferably one-way conveyor belt devices, and their conveyor belts are driven by a one-way rotating motor.
[0050] Furthermore, the front and rear conveying mechanism 2 is a bidirectional conveyor belt device with a lifting function.
[0051] In this embodiment, the front and rear conveying mechanisms 2 need to have bidirectional conveying functions and lifting functions, so the front and rear conveying mechanisms 2 are preferably bidirectional conveyor belt devices with lifting functions, and their conveyor belts are driven by forward and reverse motors and controlled by the main controller; their conveyor belt device frames are equipped with lifting motors, and the lifting of the device frame is controlled by the main controller, thereby lifting and lowering the conveyor belt.
[0052] Furthermore, the horizontal conveying part 31 is a one-way conveyor belt device, and the slope conveying part 32 is a one-way inclined conveyor belt device.
[0053] In this embodiment, when the front and rear conveying mechanisms 2 convey forward, the front and rear conveying mechanisms 2, the horizontal conveying part 31 and the slope conveying part 32 form a one-way conveying line to convey the damaged plate-like objects forward to the damaged collection tank 33, so the horizontal conveying part 31 is preferably a one-way conveyor belt device, and the slope conveying part 32 is preferably a one-way inclined conveyor belt device, and their conveyor belts are driven by a one-way rotating motor.
[0054] Other structures and operations of a production line plate-like object damage detection structure according to an embodiment of the utility model are known to ordinary technicians in the field and will not be described in detail here.
