Description

Technical Field

[0001] The invention belongs to the technical field of bagging, and in particular relates to a color mark detection and correction device and a color mark detection and correction method. Background Art

[0002] During the injection molding and filling process, the raw material film used is pre-printed with color codes and packaging instructions at intervals. Each set of color codes and packaging instructions corresponds to each other. After the raw material film is formed, each packaging material will correspond to a set of color codes and label instructions. In the ideal state, the color code and label instructions on each packaging material are located in the middle of the packaging material. However, in the actual molding and filling process, due to the limitations of equipment accuracy, equipment technology and other issues, as the molding and filling process continues, the movement of the raw material film will deviate, resulting in a deviation in the position of the color code on the packaging material (not in the middle of the packaging material), affecting the quality of the molded packaging material.

[0026] The structure of the present invention will now be described in further detail with reference to the accompanying drawings.

[0027] Example 1

[0028] like Figure 1 and Figure 2 As shown, this embodiment 1 provides a color mark detection and correction device, including: a control module, a color mark detection module 10, a pulling mechanism 20, and a correction mechanism 30; wherein the control module is suitable for controlling the pulling mechanism 20 to pull the raw material film 40 to move toward the subsequent process according to a preset travel distance; the color mark detection module 10 is suitable for detecting the color mark signal on the moving raw material film 40 and sending it to the control module; and when the color mark detection module 10 does not detect the color mark signal, the control module is suitable for controlling the correction mechanism 30 to correct the pulling distance of the pulling mechanism 20 to correct the travel distance of the raw material film 40.

[0029] Specifically, the color mark detection and correction device of this embodiment is suitable for detecting the color mark signal on the moving raw material film 40 through the color mark detection module 10, and when the color mark detection module 10 fails to detect the color mark signal, the correction mechanism 30 timely corrects the pulling distance of the pulling mechanism 20 to correct the moving distance of the raw material film 40, thereby ensuring that the raw material film 40 accurately enters the subsequent process and improves the subsequent molding quality of the raw material film 40.

[0030] In this embodiment, it is used as an implementation mode of the color mark detection and correction device.

[0031] The color mark detection and correction device further includes: a traction mechanism 50 controlled by a control module; the traction mechanism 20 and the correction mechanism 30 are both located on the traction mechanism 50; the traction mechanism 50 is suitable for driving the correction mechanism 30 and the traction mechanism 20 to synchronously move toward a subsequent process according to a preset travel distance; the traction mechanism 20 is suitable for clamping the raw material film 40 when moving toward the subsequent process to pull the raw material film 40 toward the subsequent process; and when the color mark detection module 10 does not detect a color mark signal, the correction mechanism 30 is suitable for pushing the traction mechanism 20 to move a preset correction distance along the traction mechanism 50 to the previous process, and after the traction mechanism 20 clamps the raw material film 40, the correction mechanism 30 is reset to correct the pulling distance of the traction mechanism 20, that is, the traction mechanism 50 drives the correction mechanism 30 and the traction mechanism 20 to move toward the subsequent process according to the sum of the preset travel distance and the preset correction distance.

[0032] Specifically, when the color mark detection module 10 detects a color mark signal, the correction mechanism 30 is not started and moves synchronously with the pulling mechanism 20; when the color mark detection module 10 does not detect a color mark signal, the correction mechanism 30 is started, that is, the pulling mechanism 20 is pushed to move a preset correction distance along the traction mechanism 50 toward the previous process, and then after the pulling mechanism 20 clamps the raw material film 40, the correction mechanism 30 can be reset, and then the traction mechanism 50 drives the correction mechanism 30 and the pulling mechanism 20 to move toward the next process according to the sum of the preset travel distance and the preset correction distance; if the color mark detection module 10 still does not detect a color mark signal after the correction mechanism 30 is calibrated once, the correction mechanism 30 repeats the calibration until the color mark detection module 10 detects a color mark signal.

[0033] In this embodiment, another implementation of the color mark detection and correction device is provided.

[0034] The color mark detection and correction device further includes: a traction mechanism 50 controlled by a control module; the traction mechanism 20 and the correction mechanism 30 are both located on the traction mechanism 50; the traction mechanism 50 is suitable for driving the correction mechanism 30 and the traction mechanism 20 to synchronously move toward a subsequent process according to a preset travel distance; the traction mechanism 20 is suitable for clamping the raw material film 40 when moving toward the subsequent process to pull the raw material film 40 toward the subsequent process; and when the color mark detection module 10 does not detect the color mark signal, the correction mechanism 30 is suitable for pushing the traction mechanism 20 to move toward the subsequent process along the traction mechanism 50 by a preset correction distance, and after the traction mechanism 20 clamps the raw material film 40, the correction mechanism 30 is reset to correct the pulling distance of the traction mechanism 20, that is, the traction mechanism 50 drives the correction mechanism 30 and the traction mechanism 20 to move toward the subsequent process according to the difference between the preset travel distance and the preset correction distance.

[0035] Specifically, when the color mark detection module 10 detects a color mark signal, the correction mechanism 30 is not started and moves synchronously with the pulling mechanism 20; when the color mark detection module 10 does not detect a color mark signal, the correction mechanism 30 is started, that is, the pulling mechanism 20 is pushed to move a preset correction distance along the traction mechanism 50 to the subsequent process, and then after the pulling mechanism 20 clamps the raw material film 40, the correction mechanism 30 can be reset, and then the traction mechanism 50 drives the correction mechanism 30 and the pulling mechanism 20 to move to the subsequent process according to the difference between the preset travel distance and the preset correction distance; if the color mark detection module 10 still does not detect a color mark signal after the correction mechanism 30 is calibrated once, the correction mechanism 30 repeats the calibration until the color mark detection module 10 detects a color mark signal.

[0036] Both of the above two implementations can realize the correction of the travel distance of the raw material film 40 . The drawings of this embodiment take the first implementation as an example for explanation.

[0037] In this embodiment, the pulling mechanism 20 includes: a pulling cylinder 21 controlled by a control module, a support plate 22, and a clamping plate 23; wherein the support plate 22 can be slidably arranged on the traction mechanism 50, and is provided with a through hole 220 suitable for the raw material film 40 to pass through; the clamping plate 23 is connected to the piston rod of the pulling cylinder 21, and is located in the through hole 220; and the pulling cylinder 21 is located on the support plate 22, and is suitable for driving the clamping plate 23 to move toward the raw material film 40 to clamp the raw material film 40.

[0038] In this embodiment, the correction mechanism 30 includes: a correction cylinder 31 located on the traction mechanism 50 and controlled by the control module; and the correction cylinder 31 is suitable for pushing the support plate 22 to drive the pull cylinder 21 along the traction mechanism 50 to move a preset correction distance toward the previous process or the next process.

[0039] Specifically, the traction mechanism 50 includes: a traction shaft 51 and a linkage assembly 52; the correction cylinder 31 is located on the traction shaft 51 through a mounting plate 32; the support plate 22 is slidably disposed on the traction shaft 51; the control module is suitable for driving the linkage assembly 52 to drive the traction shaft 51 to move, thereby driving the correction cylinder 31 and the pulling cylinder 21 to move along the traction shaft 51.

[0040] In this embodiment, the color mark detection module 10 includes: a color mark detection sensor 11 .

[0041] Example 2

[0042] Based on Example 1, this Example 2 provides a color mark detection and correction method, including: driving the traction mechanism 20 through the traction mechanism 50 to pull the raw material film 40 to the subsequent process according to a preset travel distance; detecting the color mark signal on the moving raw material film 40 through the color mark detection module 10; and when the color mark detection module 10 fails to detect the color mark signal, correcting the pulling distance of the traction mechanism 20 through the correction mechanism 30 to correct the travel distance of the raw material film 40.

[0043] Furthermore, the pulling mechanism 20 and the correction mechanism 30 are both located on the traction mechanism 50; the correction mechanism 30 and the pulling mechanism 20 are driven by the traction mechanism 50 to synchronously move toward the subsequent process at a preset moving distance; and when the pulling mechanism 20 and the correction mechanism 30 move toward the subsequent process, the pulling mechanism 20 can clamp the raw material film 40 to pull the raw material film 40 to move toward the subsequent process.

[0044] As an implementation method of this embodiment.

[0045] The method for correcting the pulling distance of the pulling mechanism 20 by the correction mechanism 30 includes: setting a preset travel distance as x, a preset correction distance as y, and a corrected travel distance as z; pushing the pulling mechanism 20 to move the preset correction distance along the traction mechanism 50 toward the previous process by the correction mechanism 30, and resetting the correction mechanism 30 after the traction mechanism 20 clamps the raw material film 40; the traction mechanism 50 drives the correction mechanism 30 and the pulling mechanism 20 to move toward the next process according to the corrected travel distance z; wherein z = x + y; if the color mark detection module 10 still fails to detect the color mark signal after correction by the correction mechanism 30, repeating the aforementioned correction process until the color mark detection module 10 detects the color mark signal.

[0046] Taking this implementation as an example, the correction principle is described in detail as follows:

[0047] As shown in Figures 3 (a) and 3 (b), with color mark No. 2 as the reference color mark, the current raw material film 40 appears to be in a state of lagging in travel distance. After one calibration, the color mark detection module 10 can detect the signal of color mark No. 2, and the calibration is completed; as shown in Figures 4 (a) to 4 (d), still with color mark No. 2 as the reference color mark, the current raw material film 40 appears to be in a state of advancing in travel distance. After three calibrations, the color mark detection module 10 can detect the signal of color mark No. 1, and the calibration is completed.

[0048] Therefore, the correction method of this embodiment can not only offset the advance travel distance of the raw material film 40 , but also compensate for the lag travel distance of the raw material film 40 .

[0049] As another implementation of this embodiment.

[0050] The method for correcting the pulling distance of the pulling mechanism 20 by the correction mechanism 30 includes: setting a preset travel distance as x, a preset correction distance as y, and a corrected travel distance as z; pushing the pulling mechanism 20 to move the preset correction distance along the traction mechanism 50 to the subsequent process by the correction mechanism 30, and resetting the correction mechanism 30 after the pulling mechanism 20 clamps the raw material film 40; the traction mechanism 50 drives the correction mechanism 30 and the pulling mechanism 20 to move to the subsequent process according to the corrected travel distance z; wherein z = x- y; if the color mark detection module 10 still does not detect the color mark signal after the correction by the correction mechanism 30, repeat the above-mentioned correction process until the color mark detection module 10 detects the color mark signal.

[0051] Specifically, the correction principle of this embodiment is similar to the correction principle of the first embodiment, which can offset the advanced travel distance of the raw material film 40 and compensate for the lagging travel distance of the raw material film 40, which will not be elaborated here.

[0052] Specifically, in the two implementations of this embodiment, the correction mechanism 30 is reset after the drawing mechanism 20 clamps the raw material film 40 and before the drawing mechanism 20 moves to the subsequent process according to the corrected travel distance z.

[0053] Specifically, the specific structures and principles of the pulling mechanism 20, the correction mechanism 30 and the traction mechanism 50 can refer to the description of the embodiment 1, which will not be repeated here.

[0054] To sum up, the color mark detection and correction device and the color mark detection and correction method can detect the color mark on the raw material film, and when the color mark detection module does not detect the color mark signal, the correction mechanism can timely correct the pulling distance of the pulling mechanism to correct the travel distance of the raw material film, thereby ensuring that the raw material film accurately enters the subsequent process and improves the subsequent molding quality of the raw material film.

[0055] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
