Description

Technical Field

[0001] The utility model belongs to the technical field of material storage pits, in particular to a material height positioning device for a material storage pit. Background Art

[0002] In the process of producing strip materials, it is essential to flatten the rolled strip materials and slit them through a slitting device. During the flattening process, a part of the strip materials will naturally fall into the storage pit.

[0003] Due to the unstable speed of the subsequent processing flow, the bottom height of this part of the strip material located in the storage pit is also unstable. It is easy for the subsequent processing speed to be too fast or the feeding to cause excess or shortage of strip material. When there is excess strip material, its bottom can easily hit the bottom of the storage pit. When there is a shortage of strip material, the angle between the discharge end of the strip material and the horizontal plane is smaller, which can easily cause the knife to break during subsequent stripping, affecting subsequent processing. Utility Model Content

[0004] In view of this, the utility model provides a material height positioning device for a storage pit to solve the above-mentioned problem.

[0005] A material height positioning device for a material storage pit, comprising a material storage pit body, and a positioning body arranged in the material storage pit body. The positioning body comprises four groups of sensor assemblies arranged on the inner wall of the material storage pit body, and three travel switches arranged on the inner wall of the material storage pit body. The sensor assemblies are arranged at intervals along the depth direction of the material storage pit body. The spacing between adjacent sensor assemblies is equal. Each of the travel switches is respectively arranged between adjacent sensor assemblies. Each of the sensor assemblies comprises a transmitting part arranged on the inner wall of the material storage pit body, and a receiving part located on the same horizontal plane as the corresponding transmitting part.

[0006] Furthermore, a feeding assembly is arranged on one side of the opening of the storage pit body, and a discharging assembly is arranged on the other side of the storage pit body.

[0007] Furthermore, the feed assembly includes two feed rotating shafts spaced apart, two first mounting plates spaced apart on one side of the feed rotating shaft, and at least one set of first guide shafts rotatably disposed between the two first mounting plates.

[0008] Furthermore, the discharging assembly includes two discharging shafts spaced apart, two second mounting plates spaced apart on one side of the discharging shaft, and at least one set of second guide shafts rotatably disposed between the two second mounting plates.

[0009] Furthermore, the height of the first guide shaft at the end of the first mounting plate is the same as the height of the second guide shaft at the end of the second mounting plate, and the distance between the first guide shaft and the inner wall of the storage pit is equal to the distance between the second guide shaft and the inner wall of the storage pit.

[0010] Further, the travel switch is located at the symmetric center between the first guide shaft at the end of the first mounting plate and the second guide shaft at the end of the second mounting plate.

[0011] Compared with the prior art, the material height positioning device for a storage pit provided by the utility model arranges a travel switch along the depth direction in the storage pit body, so that the bottom of the arc formed by the strip material after hanging down in the storage pit body passes through the uppermost and lowermost two travel switches, and control signals can be formed respectively, thereby controlling the deceleration or acceleration of the rotation of the discharge component, and then adjusting the bottom height of the strip material in the storage pit body. The sensor is arranged so that the position of the strip material in the storage pit body can be continuously detected to avoid accidental touch or damage of the travel switch during use, which causes the strip material to be too high or too low.

[0015] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0016] like Figures 1 to 3As shown, it is a schematic diagram of the structure of the material height positioning device for a material storage pit provided by the utility model. The material height positioning device for a material storage pit includes a material storage pit body 10, a positioning body 20 arranged in the material storage pit body 10, a feeding assembly 30 arranged on one side of the material storage pit body 10, and a discharging assembly 40 arranged on the other side of the material storage pit body 10. The material height positioning device for a material storage pit also includes some other functional modules, such as a control circuit arranged in the material storage pit body 10 and connected to the positioning body 20, etc., which should be technologies well known to those skilled in the art and will not be described in detail one by one here.

[0017] The material storage pit body 10 is a cylindrical pit. The cross section of the material storage pit body 10 is rectangular and its inner wall is arranged vertically. The material storage pit body 10 is used to store naturally falling strip materials. A horizontal surface 11 is arranged around the material storage pit body 10 to facilitate the installation of various equipment on the production line.

[0018] The positioning body 20 includes four groups of sensors 21 spaced apart along the depth direction of the material storage pit 10 , and three travel switches 22 spaced apart along the depth direction of the material storage pit 10 .

[0019] Each group of sensors 21 is spaced and arranged equidistantly. Each group of sensors 21 includes a transmitter 211 arranged on the side wall of one side of the storage pit body 10, and a corresponding receiver 212 arranged on the side wall of the other side of the storage pit body 10. Each transmitter 211 and the corresponding receiver 212 are located at the same height, and the signal emitted by each transmitter 211 is received by the corresponding receiver 212. When the strip material sags, the strip material will block the receiving part 212 at the corresponding position from top to bottom, so that the blocked receiving part 212 cannot receive the corresponding signal. The sensor 21 continuously detects the position of the strip material, and the position of the strip material in the storage pit body 10 can be obtained through continuous detection by the four sensors 2. When the strip material passes through the travel switch 22, the controller needs to determine whether it is touched by mistake based on the detection information of the sensor 21 at the same time.

[0020] The travel switches 22 are respectively arranged between the adjacent sensors 21. The travel switches 22 are distributed at the symmetric axis of the curve formed by the natural bending of the strip material. When the bottom of the strip material rises or falls, the bottom of the strip material will pass through the travel switch 22. At this time, the travel switch 22 will receive a signal and control the feed assembly 30 and the discharge assembly 40 to accelerate or decelerate, so that the strip material returns to its original position.

[0021] The feed assembly 30 includes a first mounting frame 31, two feed rotating shafts 32 installed at intervals in the first mounting frame 31, a guide plate 33 arranged in front of the feed rotating shaft 32, two first mounting plates 34 vertically and spaced apart at the rear of the feed rotating shaft 32, and at least one first rotating shaft 35 rotatably inserted between the first mounting plates 34.

[0022] The first mounting frame 31 is disposed on one side of the material storage pit body 10 to provide a mounting position.

[0023] The two feeding rotating shafts 32 are rotating rollers whose surfaces are in contact with each other, so as to drive the strip material into the storage pit body 10 after rotation. The speed of the feeding rotating shaft 32 is controllable, and the speed adjustment is obtained by analyzing the information detected by the travel switch 22 and the sensor 21. The specific adjustment method is described in detail below.

[0024] The guide plate 33 includes a plate body 331 and a first cylinder 332 whose two ends are respectively hinged to the plate body 331 and the horizontal platform 11. The first cylinder 332 is controlled to extend or retract, thereby lifting the end of the plate body 331, thereby supporting and guiding the strip material.

[0025] The two first mounting plates 34 are fixedly mounted on the first mounting frame 31 and are located on one side of the first mounting frame 31 close to the material storage pit 10, thereby providing a mounting position for the first rotating shaft 35. At the same time, when the strip material is transmitted on the first rotating shaft 35, it has a certain protection and limiting effect on the strip material. The top of the first mounting plate 34 is arc-shaped, and the first rotating shafts 35 are arranged along the arc-shaped contours of the first mounting plate 34.

[0026] The first rotating shaft 35 is used to guide the position of the strip material so that the strip material falls into the material storage pit 10 along the distribution of the first rotating shaft 35 .

[0027] The discharge assembly 40 includes a second mounting frame 41 arranged on the other side of the storage pit body 10, two discharge shafts 42 rotatably arranged on the second mounting frame 41, two second mounting plates 43 spaced apart on one side of the discharge shaft 42, and at least one second rotating shaft 44 arranged between the two second mounting plates 43.

[0028] The second mounting frame 41 is used to provide a mounting position. The second mounting frame 41 and the first mounting frame 31 are respectively arranged on two opposite sides of the material storage pit body 10 and are located at the edge of the material storage pit body 10.

[0029] The discharging shaft 42 is controlled to rotate, so as to deliver the material in the storage pit 10 to the subsequent stripping assembly. The speed control of the discharging shaft 42 is related to the information detected by the travel switch 22 and the sensor 21, and the specific content will be described in detail below.

[0030] The second mounting plate 43 is fan-shaped and provides a mounting position for the second rotating shaft 44 .

[0031] The second rotating shaft 44 is used to guide the position of the strip material so that the strip material is distributed along the second rotating shaft 44 and is smoothly fed into the second rotating shaft 44 .

[0032] The first rotating shaft 35 at the end of the first mounting plate 34 and the second rotating shaft 4 at the end of the second mounting plate 43 are at the same height, and the distance between the two and the inner wall of the storage pit 11 is the same, so that when the speed of the strip material is stable, the lowest point of the strip material after naturally falling is close to the symmetry axis of the storage pit 10. The travel switch 22 is arranged here to obtain more accurate information.

[0033] During use, a motor is disposed on one side of the feed assembly 30 and the discharge assembly 40 respectively, for driving the feed assembly 30 and the discharge assembly 40 to rotate respectively. The sensor 21 continuously detects the position of the strip material.

[0034] During normal operation, the strip material is located at the middle travel switch 22. When the bottom of the strip material drops and passes the lowest travel switch 22, the second driving shaft 44 of the discharging assembly 40 is controlled to accelerate the rotation, thereby accelerating the strip material out of the storage pit 10; when the bottom of the strip material rises and passes the highest travel switch 22, the second driving shaft 44 of the feeding and discharging assembly 40 is controlled to accelerate the rotation, thereby leaving the strip material in the storage pit 10. After speed adjustment, the second driving shaft 44 will restore the original speed. It is noted that the speed of the feeding assembly 30 can also be adjusted. In actual use, the height adjustment of the strip material can be accelerated by adjusting the speeds of the feeding assembly 30 and the feeding assembly 40 at the same time.

[0035] Compared with the prior art, the material height positioning device for the storage pit provided by the utility model sets three travel switches 22 in the depth direction in the storage pit body 10, so that the bottom of the arc formed by the strip material after hanging in the storage pit body 10 can form a control signal respectively after passing through the uppermost and lowermost two travel switches 22, thereby controlling the discharge component 40 to slow down or accelerate the rotation, and then adjust the bottom height of the strip material in the storage pit body 10. The sensor 21 is set, so that the position of the strip material in the storage pit body 10 can be continuously detected to avoid the travel switch 22 being accidentally touched or damaged during use, resulting in the strip material being too high or too low.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention are included in the scope of the claims of the present invention.
