Description

Technical Field

[0001] The utility model relates to the field of strip material transportation, in particular to an automatic unloading device suitable for strip materials of different lengths. Background Art

[0002] Existing long strip workpieces such as steel pipes and iron bars often need to go through processes such as forming, cutting, blanking, and weighing in the production process. In the prior art, after multiple strip workpieces are cut and blanked, they are usually weighed together through a weighing mechanism. However, in the actual production process, the length of the strips is often not uniform, and the automatic strip blanking device in the prior art is unable to adjust the blanking position of the strips according to the length of the strips, thereby failing to ensure that the middle of each strip is blanked from the blanking position during blanking. As a result, in the subsequent weighing process, it is impossible to ensure that the middle of each strip is located at the center of the weighing mechanism. This deficiency directly leads to the instability of the weighing results. When the strip deviates from the center of the weighing mechanism, the data received by the weighing sensor will deviate, thereby affecting the accuracy of the weighing results. This error not only affects the precise control of the weight of the raw materials, but may also have a series of adverse effects on subsequent production plans, cost control, and product quality.

[0003] Therefore, in an environment where the requirements for weighing measurement accuracy are getting higher and higher, how the automatic unloading device adjusts the unloading position according to the length of the strip material is a technical problem that technicians in this field urgently need to solve.

[0027] See also Figures 1 to 5, provides an automatic unloading device suitable for strips of different lengths, including a support frame 13, a control center 17 is provided on the top of the support frame 13, and a conveying mechanism 11 is arranged along the X direction, the control center 17 can receive the length information of the strip 3 being conveyed at this time in advance, and the control center 17 determines whether the strip 3 being conveyed at this time is long or short according to the length information of the strip 3, and the clamping and discharging trolley makes different transportation processes according to short or long materials. When the strip 3 is short, it arrives at the designated position and directly pushes out the unloading; when the strip 3 is long, a clamping and transportation process is added, and the control center 17 can control the clamping and discharging trolley 15 to clamp the long material and move it to the designated position before pushing it out for unloading, ensuring that whether it is short or long material, the middle position of the strip can be accurately corresponding to the discharging inclined guide plate during unloading, so that the middle position of each strip is in the same position after unloading, ensuring that the middle position of each strip is located at the center of the weighing mechanism in the subsequent weighing process, thereby improving the weighing accuracy, and the following provides an embodiment:

[0028] The conveying mechanism 11 is a plate chain conveying mechanism, and a discharging inclined guide plate 12 is provided on one side of the conveying mechanism 11; a clamping and discharging trolley 15 capable of reciprocating along the X direction is also provided on the upper side of the conveying mechanism 11, and the clamping and discharging trolley 15 includes a main body, a detection mechanism is provided on the main body along the X direction, and a clamping and discharging mechanism is provided along the Y direction; a trolley drive assembly 14 is provided on the other side of the conveying mechanism 11, and the trolley drive assembly 14 is driven and connected to the main body, and the trolley drive assembly 14 includes a drive motor and a ball screw connected to the output end of the drive motor, the ball screw is arranged along the X direction, and the bottom of the body is connected to the ball screw; the control center 17 is respectively controlled and connected to the conveying mechanism 11, the clamping and discharging trolley 15 and the trolley drive assembly 14, and the trolley drive assembly 14 can move on the ball screw through the drive motor according to the instruction of the control center 17, thereby improving the flexibility of the trolley drive assembly 14.

[0029] See also Figures 2 to 4 The clamping and discharging mechanism includes a discharging baffle 154, a first driving member 151, a second driving member 156, and a thrust plate 157. The discharging baffle 154 is movably arranged at one end of the main body along the Y direction close to the discharging inclined guide plate 12. The discharging baffle 154 is connected to the first driving member 151, and under the action of the first driving member 151, the discharging baffle 154 can be in an open position or a closed position. The second driving member 156 is arranged in the main body along the Y direction, and the thrust plate 157 is provided at the output end of the second driving member 156. The thrust plate 157 is located on the inner side of the discharging baffle 154.

[0030] Specifically, when the discharge baffle 154 is in the closed position, a material passage for the strip material 3 to pass through is formed between the thrust plate 157 and the discharge baffle 154, and by changing the position of the thrust plate 157, the thrust plate 157 and the discharge baffle 154 can clamp and convey the strip material 3; when the discharge baffle 154 is in the open position, the thrust plate 157 can push the strip material 3 to leave the conveying mechanism 11 and fall along the discharge inclined guide plate 12. The side of the discharge baffle 154 close to the main body is hinged to the main body through a third rotating shaft 155, and the side away from the main body is hinged to the first driving member 151 through a second rotating shaft 153. The first driving member 151 is extended and retracted along the Y direction and drives the discharge baffle 154 to rotate between the open position and the closed position with the third rotating shaft 155 as the axis. Since the trolley drive assembly 14 can move in the X direction, the thrust plate 157 and the discharge baffle 154 can also adjust the clamping position of the strip material 3 accordingly.

[0031] See also Figure 5 The detection mechanism includes a detection baffle assembly 16 and a third driving member 164. The detection baffle assembly 16 is movably arranged on one side of the body away from the feeding end of the strip material 3 along the X direction. The detection baffle assembly 16 is connected to the third driving member 164, and under the action of the third driving member 164, the detection baffle assembly 16 can be in an open position or a closed position.

[0032] Specifically, the detection baffle assembly 16 includes a detection baffle 161 and a detector 163. The detector 163 is disposed on the surface of the detection baffle 161 near the bottom. Since the detector 163 is located at a lower position, even if the diameter of the strip 3 is relatively small, the detector 163 can still detect it, thus providing a wide range of applications. The third driving member 164 is provided with a connecting shaft 165 at its end. The connecting shaft 165 is disposed in a matching connecting buckle 162 at the top of the detection baffle 161. The third driving member 164 extends and retracts along the X-direction and drives the detection baffle 161 to rotate between an open position and a closed position about the connecting shaft 165.

[0033] The specific implementation steps of this embodiment are:

[0034] S1. The device is restored to its initial state. At this time, the clamping and discharging trolley 15 is located at the discharging position. That is, the center position of the clamping and discharging trolley 15 is arranged opposite to the center position of the discharging inclined guide plate 12. The discharging baffle 154 and the detection baffle 161 are both in the closed position. A material passage for the strip material 3 to pass through is formed between the thrust plate 157 and the discharging baffle 154.

[0035] S2. The control center 17 receives the length information of the strip material 3 to be conveyed, and the conveying mechanism 11 conveys the strip material 3 along the X direction until the end of the strip material 3 contacts the detection baffle assembly 16. The detection baffle assembly 16 feeds back a signal to the control center 17, and the control center 17 controls the conveying mechanism 11 to stop moving. When the length of the strip material 3 is greater than a certain set value, the process proceeds to step S3; when the length of the strip material 3 is less than a certain set value, the process proceeds to step S5.

[0036] S3. The control center 17 calculates the center position of the strip 3 according to the length of the strip 3, the third driving member 164 drives the detection baffle assembly 16 to move to the open position, and the control center 17 controls the clamping and discharging trolley 15 to move along the X direction to the center position of the strip 3 and stop;

[0037] S4, the second driving member 156 drives the thrust plate 157 to move toward the discharge baffle 154 until the thrust plate 157 and the discharge baffle 154 clamp the strip 3, and the control center 17 controls the clamping and discharging trolley 15 to clamp the strip 3 and move in the opposite direction along the X direction to the discharge position and stop;

[0038] S5. The first driving member 151 drives the discharge baffle 154 to move to the open position, and the second driving member 156 drives the thrust plate 157 to move toward the discharge baffle 154 until the strip material 3 is pushed to leave the conveying mechanism 11 and fall from the discharge inclined guide plate 12, completing the automatic unloading of the strip material 3.

[0039] The utility model provides an automatic unloading device suitable for strips of different lengths, so that the middle position of each strip is in the same position after unloading, ensuring that the middle position of each strip is located at the center of the weighing mechanism during the subsequent weighing process, thereby improving the weighing accuracy.
