Description

Technical Field

[0001] This application relates to a cotton-applying machine, and more particularly to an interference detection device for detecting whether there are interfering substances adhering to the bottom of the pressure plate of the cotton-applying machine. Background Technology

[0002] Flat die-cutting molds are commonly used tools in the packaging industry. They are equipped with blades that cut or crease packaging materials to meet usage requirements.

[0003] Typically, elastic material, such as foam or sponge, is also provided on the cutting template on both sides of the blade. This elastic material adheres to the cutting template and is located on both sides of the blade, thus encasing the blade within it. The blade is only exposed when the elastic material is compressed during cutting. This design serves two purposes: first, it protects the blade, minimizing damage from impacts during non-working hours; second, after cutting the packaging material, the compressed elastic material returns to its original position, lifting the packaging material and detaching it from the blade.

[0004] The applicant has developed an automatic sponge applicator machine. A gripper head picks up sponge strips and attaches them to a die template. When the sponge strip is placed on the die template, the pressure plate of the gripper head presses the strip firmly against the template, and the pins of the gripper head retract upwards, thus removing the sponge strip. After this process, the gripper head proceeds to the next cycle of picking up and attaching sponge strips to the die template. However, sometimes sponge strips accidentally adhere to the bottom of the pressure plate, preventing them from being properly attached to the die template. This interferes with the normal operation of the next cycle and causes unnecessary losses.

[0005] Therefore, an interference detection device for the pressure plate of a cotton-applying machine has become a necessity. Utility Model Content

[0006] In view of at least one of the above technical problems, this application provides an interference detection device for the pressure plate of a cotton applicator.

[0008] As a further improvement of this utility model, the detection range of the laser sensor is located below the pressure plate.

[0009] As a further improvement of this utility model, the pressure plate can rotate in either the forward or reverse direction.

[0010] As a further improvement of this utility model, a plurality of through holes are provided through the upper and lower surfaces of the pressure plate, and a retractable pin is provided above the pressure plate corresponding to the through holes.

[0014] As a further improvement of this utility model, the pressure plate can rotate 360°.

[0015] As a further improvement of this utility model, the laser sensor emits a laser irradiation line towards the pressure plate.

[0025] like Figures 1 to 7 As shown, an embodiment of this application provides an interference detection device for the pressure plate of a cotton applicator, which includes: a laser sensor 2 and a pressure plate 1. The pressure plate 1 can rotate around its own central axis. The laser sensor 2 is disposed on one side of the pressure plate 1 and faces the pressure plate 1. The detection range of the laser sensor 2 extends up to or beyond the diameter endpoint of the pressure plate 1 that is away from the laser sensor 2.

[0026] In other embodiments, other sensors, such as infrared sensors, can also be used, as long as they can detect whether there is an interfering object 4 attached to the bottom of the pressure plate 1.

[0027] The detection range of the laser sensor 2 is located below the pressure plate 1.

[0028] The pressure plate 1 can rotate in either the forward or reverse direction. Since the laser sensor 2 emits a laser irradiation line 3, when the pressure plate 1 rotates in either direction, the area below the pressure plate 1 can be scanned by the laser irradiation line 3, thereby avoiding missed detections.

[0029] In this application, the interfering object 4 is a sponge strip with a certain thickness. Before detection, the irradiation height and range of the laser irradiation line 3 will be adjusted according to the thickness parameter of the sponge strip. When the interfering object 4 passes through the position of the laser irradiation line 3, it can intersect with the laser irradiation line 3.

[0030] Several through holes are provided through the upper and lower surfaces of the pressure plate 1, and retractable pins 5 are provided above the pressure plate 1 corresponding to the through holes. When the pins 5 pass through the lower surface of the pressure plate 1, they are inserted into the sponge strip, causing the sponge strip to move with the gripper tool head. When the sponge strip is moved to the position to be pasted on the die template and pasted, the pins 5 will retract, either retracting into the through holes or leaving the upper surface of the pressure plate 1, and the pressure plate 1 will press the sponge strip firmly. When the pressure plate 1 also moves upward, it may lift the sponge strip. At this time, the sponge strip adhering to the bottom surface of the pressure plate 1 becomes an interference 4, which will interfere with the normal progress of the next process.

[0031] The inspection range of the laser sensor 2 extends to the diameter endpoint of the pressure plate 1 furthest from the laser sensor 2. In this embodiment, it is preferable that the inspection range of the laser sensor 2 covers the diameter endpoint of the pressure plate 1 furthest from the laser sensor 2. If there is an interfering substance 4 adhering to the bottom of the pressure plate 1, no missed detection will occur after the pressure plate 1 is rotated 360°.

[0032] The laser sensor 2 is positioned toward the central axis of the pressure plate 1.

[0033] The laser irradiation line 3 emitted by the laser sensor 2 is located below the pressure plate 1 and is parallel to the pressure plate 1. The laser irradiation line 3 is set parallel to the base. As long as the distance between the laser irradiation line 3 and the lower surface of the base is less than the height of the interferometer 4, and the height of the interferometer 4 is the thickness of the sponge strip, there will be no missed detection.

[0034] The pressure plate 1 can rotate 360°.

[0035] The laser sensor 2 emits a laser irradiation line 3 towards the pressure plate 1. When there is an interfering object 4 adhering to the bottom of the pressure plate 1, the laser sensor 2 receives a feedback signal; when there is no interfering object 4 under the pressure plate 1, the laser sensor 2 does not receive a feedback signal.

[0036] The interference element 4 is a sponge strip.

[0037] During operation, the inserter 5 moves to the next sponge-picking position to prepare to insert the sponge strip. During this movement, the pressure plate 1 rotates at a set angle. If the laser sensor 2 does not receive a feedback signal, the inserter 5 inserts the sponge strip, and the next cycle of sponge strip processing begins, attaching the sponge strip to the flat die. If the pressure plate 1 rotates at the set angle and the laser sensor 2 receives a feedback signal, it means that the laser sensor 2 has detected an interference object 4 adhering to the bottom of the pressure plate 1. At this time, the machine stops running and issues a warning. After the operator removes the interference object 4, the next cycle of sponge strip processing continues.

[0038] This utility model is reasonably and ingeniously designed, and can accurately detect whether there is an interference object 4 adhering to the bottom of the pressure plate 1. When the interference object 4 is detected, it can feed the signal back to the equipment, the machine stops running and issues a warning, thereby reminding the staff to quickly clean the interference object, avoiding the possibility of damage to the equipment, cutting template and finished product in the next process, saving costs and ensuring the normal and orderly operation of production.

[0039] The above description is merely a preferred embodiment of this application and does not constitute any limitation on this application. Any person skilled in the art can make many possible variations and modifications to the technical solution of this application, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this application. Therefore, all equivalent changes made based on the shape, structure, and principle of this application without departing from the content of the technical solution of this application should be covered within the protection scope of this application.
