Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figures 1-3 An automatic roll-changing device for a fabric inspection machine according to an embodiment of this utility model includes a conveyor belt 1 and a roll-changing mechanism 2. The conveyor belt 1 is used to place multiple fiberglass fabric rolls a and to transport the fiberglass fabric rolls a to the roll-changing mechanism 2. The roll-changing mechanism 2 is located at the end of the conveyor belt 1 in the conveying direction and includes a pair of swing modules 3 mirror-arranged on both sides of the conveyor belt 1. The swing module 3 includes a mounting plate 31, a support 32, a gripper 33, and a first swing rod 34. The first swing rods 34 of the pair of swing modules 3 are connected by a synchronizing rod 4 to move synchronously.

[0028] The mounting plate 31 is provided with an arc-shaped groove 311; one end of the first swing rod 34 along its length direction is connected to the support 32, and the other end of the first swing rod 34 along its length direction is disposed in the groove 311 and serves as a movable end; the gripper 33 is disposed on the movable end of the first swing rod 34.

[0029] When the first swing rod 34 swings to the top of the groove 311, the gripper 33 faces upward, and at this time the gripping part of the gripper 33 is open and can accommodate the roller of the glass fiber cloth roll a. When it is necessary to change the roll, the conveyor belt 1 conveys a roll of glass fiber cloth a to the front end, so that the roller of the glass fiber cloth roll a enters the gripping part of the gripper 33, and then the gripper 33 grips the roller of the glass fiber cloth roll a to complete the acquisition.

[0030] When the first swing rod 34 swings to the bottom of the groove 311, the gripper 33 flips at a preset angle, and then the gripper 33 releases the glass fiber cloth roll a onto the inspection machine, thus completing the roll change.

[0031] In this embodiment, it should be noted that before changing the roll, the operator first removes the roller that has been fully unwound on the fabric inspection machine and places it on the take-up roller group at the rear end of the fabric inspection machine to rewind the fiberglass cloth. Furthermore, this embodiment does not limit the rotation angle of the gripper 33; its rotation angle should be no less than 90° and no more than 180°, depending on the arrangement of the device and the fabric inspection machine. In practical applications, it is only necessary to satisfy the requirement of releasing the roller of fiberglass cloth roll a.

[0032] In this embodiment, the automatic roll-changing device for the fabric inspection machine conveys a roll of fiberglass cloth a to the roll-changing mechanism 2 via conveyor belt 1. The roll-changing mechanism 2 then places the fiberglass cloth onto the unloading roller group of the fabric inspection machine. This eliminates the need for manual handling of the fiberglass cloth roll a, automatically changing the roll on the inspection machine, thereby reducing the labor intensity of workers and improving the efficiency of fabric inspection. Furthermore, the automatic roll-changing device in this embodiment uses grippers 33 to grasp the fiberglass cloth roll a, significantly improving the reliability of the roll-changing process.

[0033] In this embodiment, preferably, the automatic roll-changing device of the fabric inspection machine further includes a first drive mechanism (not shown in the figure); the first drive mechanism is connected to one of the swing modules 3 in a transmission manner; the first drive mechanism is signal-connected to the PLC controller and is used to drive the movable end of the first swing rod 34 to swing along the groove 311. The first drive mechanism is a motor, and its output end is connected to one end of the first swing rod 34 that is disposed on the support 32, thereby driving the first swing rod 34 to rotate around the support 32.

[0034] In this embodiment, to increase the degree of automation, the automatic roll-changing device of the fabric inspection machine also includes a PLC controller (not shown in the figure). The PLC controller is used to realize the fixed-length conveying of the conveyor belt 1, the swinging of the first swing rod 34, and the tightening and loosening of the gripper 33. Since the PLC controller is a well-known technology in the art, its control method will not be described in detail in this embodiment for the sake of simplicity.

[0035] refer to Figure 2 In this embodiment, specifically, the movable end of the first swing rod 34 is provided with a first roller 341; the first roller 341 is slidably connected within the groove 311. Under the above design, the first roller 341 effectively increases the stability of the flipping motion of the gripper 33, enabling it to slide stably along the groove 311.

[0036] In this embodiment, more specifically, the swing module 3 further includes a second swing rod 35; the first swing rod 34 and the second swing rod 35 move synchronously; one end of the first swing rod 34 along its length is connected to the support 32, and the other end of the second swing rod 35 along its length is a movable end and is provided with a second roller 351; the second roller 351 is slidably connected to the outer wall of the mounting plate 31. Of course, this design requires the outer wall of the mounting plate 31 to be designed as an arc shape matching the groove 311. Under this design, the second swing rod 35 can further increase the stability of the flipping movement of the gripper 33, enabling it to slide stably along the groove 311.

[0037] As a preferred embodiment, the gripper 33 is an electric gripper. Of course, this embodiment does not limit the type of gripper 33; for example, those skilled in the art can choose a pneumatic gripper or a hydraulic gripper according to the actual situation.

[0038] In this embodiment, specifically, the conveyor belt 1 is a chain conveyor belt, including a frame 11, a pair of conveyor chains 12 and their sprockets 13 symmetrically arranged on both sides of the frame 11, and a second drive mechanism (not shown in the figure) arranged on the frame 11 for driving the pair of conveyor chains 12 and their sprockets 13 to move synchronously. The second drive mechanism is a motor, which drives the sprockets 13 on both sides to rotate through a driving wheel 14 and a driven wheel 15.

[0039] In this embodiment, in order to improve the accuracy of conveying and prevent the glass fiber cloth roll a from failing to accurately enter the gripping part of the gripper 33, the conveyor chain 12 is provided with a plurality of slots 121 for positioning the glass fiber cloth roll a, and the roller of the glass fiber cloth roll a is placed into the slots 121 to achieve positioning.

[0040] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
