Description

Technical Field

[0001] This invention relates to the field of explosion-proof film roll transportation technology, and more specifically to a transportation device for explosion-proof film rolls. Background Technology

[0002] Explosion-proof film, as a thin film that enhances the impact resistance of glass or other brittle materials, is widely used in construction, automotive, and other fields. The transportation and storage of the explosion-proof film rolls are crucial steps in its manufacturing process. The finished rolls of explosion-proof film must be manually removed from the winding rollers of the production equipment, and the film roll ends must be manually straightened and sealed to prevent loosening. Only after this process can the film be transported to the warehouse for storage, awaiting subsequent sales or processing.

[0003] Currently, existing short-distance transportation devices for explosion-proof membrane rolls after disassembly within the workshop generally use manual hydraulic forklifts or electric tractors with special pallets for transport. This traditional transportation method requires manual handling and placement of the membrane rolls. The loading and unloading of the membrane rolls during transportation is relatively labor-intensive and resource-intensive. Moreover, this simple stacking method makes it easy for the membrane rolls to roll and slide and collide when encountering uneven workshop surfaces or when starting, stopping, or accelerating. This can not only cause them to fall and be damaged, but also pose safety hazards to workshop personnel. It can also cause the membrane layer to deform, affecting subsequent use. Furthermore, most of the limiting structures are of fixed size and cannot flexibly adapt to explosion-proof membrane rolls of different diameters, resulting in poor versatility and increased equipment costs.

[0004] Based on this, the present invention designs a transportation device for explosion-proof film rolls to solve the above problems. Summary of the Invention

Protective side frames are movably mounted on both sides of the AGV body; The insert rod is inserted into the mandrel set in the membrane roll and locked in place, with its two ends placed in the V-shaped slots of the corresponding support frames on both sides.

[0007] As a preferred embodiment of the present invention, the servo motor is fixedly installed at the center of the upper end of the top plate, the upper end of the limiting rod is fixedly connected to the lower end of the top plate, the lower end of the limiting rod is fixedly connected to the upper end of the AGV body, and the upper end of the AGV body is provided with a groove that matches the support frame that is integrally formed by the sliding block and the V-shaped bracket.

[0008] As a preferred embodiment of the present invention, the support frame includes: The frame serves as the support for the entire structure; V-shaped slots are symmetrically opened at the top of the frame, and each V-shaped slot is provided with a flexible anti-slip pad. The mounting post is fixedly installed on one side of the frame and is used to be inserted into the adjustment hole. A threaded post is provided at the end of the mounting post; A fixing nut, threaded onto the threaded post, is used for the installation and fixing of the support frame and the upright plate.

[0009] As a preferred embodiment of the present invention, the lower end of the protective side frame is provided with a rotating shaft, the two ends of the rotating shaft are respectively movably connected to the inside of the AGV body, and one end of the rotating shaft is provided with a micro motor, which is embedded in the inside of the AGV body and is used to drive the protective side frame to fold up or flip down to a flat position.

[0010] As a preferred embodiment of the present invention, the insertion rod includes: The rod body, which is a hollow tube, is used to support the insertion of the membrane roll; A positive and negative threaded rod is movably disposed inside the rod body, and a handwheel is provided at one end extending out of the rod body; A bearing is provided at the connection point of the protruding end of the positive and negative threaded rods to support the positive and negative threaded rods. The threaded portions are symmetrically arranged on the positive and negative threaded screws, and the two threaded portions have opposite directions of rotation; A fixing block is fixedly connected to the inside of the rod body. Two fixing blocks are symmetrically arranged inside the rod body, and the fixing blocks are threadedly connected to the threaded part of the rod body. The movable blocks are movably disposed inside the rod body. Two movable blocks are symmetrically arranged inside the rod body, and the movable blocks are threadedly connected to the threaded part of the rod body. Hinged seats are symmetrically arranged on opposite sides of the fixed block and the movable block; The connecting rod is movably hinged to a hinge seat on the opposite side of the fixed block and the movable block; The abutment block is movably hinged to the upper ends of the two opposite connecting rods.

[0011] As a preferred embodiment of the present invention, a through groove is provided inside the rod body corresponding to the location of each contact block, so that the contact block can be pushed outward and upward from inside the rod body.

[0012] As a preferred embodiment of the present invention, both the contact surface of the contact block and the contact surface of the film roll are provided with anti-slip flexible pads for flexible locking and fixing of the film roll, thereby achieving positioning.

[0013] As a preferred embodiment of the present invention, it further includes a control component disposed on the AGV body, for receiving scheduling instructions and controlling the movement of the AGV body, the lifting and lowering of the lifting component and the flipping action of the protective side frame, so as to realize automated transportation.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention features downward-flipping protective side frames on both sides of the AGV vehicle body. These protective side frames are driven by a micro motor. During normal transport, the side frames fold upward to protect the film rolls. When loading or unloading, simply control the motor to flip the protective side frames downward, allowing them to lie flat on the ground. The explosion-proof film rolls can be directly loaded and unloaded via the protective side frames. Then, a servo motor drives the rotation of the threaded rod to raise and lower the sliding block, lifting the rolled explosion-proof film rolls to the required height. The film rolls are then secured by the insertion rod and support frame, achieving anti-slip fixation and allowing for spaced storage of the explosion-proof film rolls. No hoisting equipment is required, and the operation can be completed by a single person. This not only limits the position of the explosion-proof film rolls and prevents them from sliding during transport, but also saves time and effort in operation. 2. This invention integrates the explosion-proof film roll storage structure onto the AGV vehicle body. During use, it is uniformly scheduled by a computer and control system, which can accurately complete the material conveying task without manual operation. Compared with traditional manually controlled hydraulic forklifts or electric tractors, it runs more smoothly and is less prone to problems such as starting bumps, thus avoiding material and equipment damage caused by human error.

[0015] 3. This invention uses an adjustable height support frame array to flexibly adapt to the storage needs of film rolls of different diameters and quantities. The unique insertion rod utilizes a positive and negative threaded screw mechanism to achieve radial tightening from the internal core of the film roll. This central locking method is more stable and space-saving than external binding or clamping, and can adapt to cores of different inner diameters, making it more versatile. Furthermore, the flexible anti-slip pads set in the V-shaped slots on the two symmetrical support frames on the left and right sides can provide anti-slip support for both ends of the insertion rod, preventing the film roll from slipping during transportation.

[0018] The following will refer to the appendices in the embodiments of the present invention. Figures 1-9The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0019] Example Please see Figures 1-9 The present invention provides the following technical solution: a transportation device for explosion-proof film rolls, including an AGV body 1, a column 2, a top plate 3, a vertical plate 4, an adjustment hole 5, a support frame 6, a servo motor 7, a protective side frame 8, a control component 9, and an insertion rod 10; The AGV vehicle body 1 serves as the basic mobile platform for the transportation device. It integrates a drive system, navigation system, and power supply, and can automatically travel along a preset path.

[0020] Furthermore, four uprights 2 are vertically fixed at the four corners of the upper part of the AGV body 1, and the top plate 3 is set on the top of the four uprights 2 and integrally formed with the uprights 2 to form the fixed frame of the upper part of the device.

[0021] Furthermore, the upright plate 4 is fixedly connected to the lower end of the top plate 3 and located between two upright columns 2 on the same side. Its lower end is connected to the upper end of the AGV body 1 to enhance the overall structural strength. Multiple rows of adjustment holes 5 are equidistantly opened on the upright plate 4 along the vertical direction for installing the support frame 6.

[0022] Furthermore, the support frame 6 is detachably installed in the adjustment holes 5 in the same row for placing and fixing the two ends of the insertion rod 10. Each support frame 6 includes a frame body 601, two V-shaped slots 602 symmetrically formed at the upper end of the frame body 601, a mounting post 603 fixed to one side of the frame body 601 for insertion into the adjustment hole 5, a threaded post 604 provided at the end of the mounting post 603, and a fixing nut 605 threadedly connected to the threaded post 604. Flexible anti-slip pads are provided in the V-shaped slots 602 to increase friction and prevent the insertion rod 10 from sliding.

[0023] Furthermore, the lifting assembly, used to lift the explosion-proof film roll to the placement height, consists of a servo motor 7, a threaded rod 701 connected to the output shaft of the servo motor 7, two parallel limiting rods 702, a sliding block 703 that slides in cooperation with the threaded rod 701 and the limiting rods 702, a V-shaped bracket 704 symmetrically fixed to the sliding block 703, and a rubber pad 705 located inside the V-shaped bracket 704. The servo motor 7 is fixedly installed at the center of the upper end of the top plate 3. The upper ends of the two limiting rods 702 are fixedly connected to the lower end of the top plate 3, and the lower ends are fixedly connected to the upper end of the AGV body 1. The upper end of the AGV body 1 has a groove that matches the support frame formed by the sliding block 703 and the V-shaped bracket 704, so that the lifting assembly can be stored when not in operation.

[0024] Furthermore, the protective side frames 8 are movably mounted on both sides of the AGV body 1 to protect the film roll during transportation. A rotating shaft 801 is provided at its lower end, and the two ends of the rotating shaft 801 are movably connected to the inside of the AGV body. One end of the shaft is connected to a micro motor 802 embedded in the body, which is used to drive the protective side frames 8 to fold up or flip down to a flat position.

[0025] Furthermore, the insertion rod 10 is used to insert into the mandrel of the membrane roll 11 and lock it in place. The insertion rod 10 mainly consists of a rod body 1001, a threaded rod 1002, a bearing 1003, a threaded part 1004, a fixing block 1005, a movable block 1006, a hinge seat 1007, a connecting rod 1008, and an abutment block 1009. The rod body 1001 is a hollow tube. The threaded rod 1002 is movably disposed inside the rod body 1001, with one end extending out of the rod body 1001 and equipped with a handwheel. The bearing 1003 is disposed at the connection point of the threaded rod 1002 extending out of the rod body 1001 and is used to support the membrane roll 11. Two threaded parts with opposite directions are symmetrically arranged on the threaded rod 1002. 1004, Two fixed blocks 1005 are fixedly connected to the inside of the rod body 1001 and arranged symmetrically, and two movable blocks 1006 are movably disposed inside the rod body 1001 and arranged symmetrically. Both the fixed blocks 1005 and the movable blocks 1006 are threadedly connected to the threaded part 1004. Hinges 1007 are symmetrically arranged on opposite sides of the fixed blocks 1005 and the movable blocks 1006. The two ends of the connecting rod 1008 are respectively movably hinged to the hinges 1007 of the fixed blocks 1005 and the movable blocks 1006. The abutment block 1009 is movably hinged to the upper end of the two connecting rods 1008. A through groove is opened inside the rod body 1001 corresponding to the position of each abutment block 1009, penetrating its tube wall.

[0026] Furthermore, the control component 9 is installed on the AGV body 1 to receive instructions from the central dispatch system and uniformly control the movement of the AGV body 1, the lifting and lowering of the lifting components, and the flipping action of the protective side frame 8 to achieve fully automated transportation.

[0027] The working principle and usage process of this invention are as follows: In specific use, the control component 9 issues an instruction to drive the AGV body 1 to the designated loading station. The micro motor 802 is controlled to drive the protective side frames 8 on both sides to flip down to a flat position, forming a slope with the ground. The operator rolls the film roll 11 to be transported along the lowered protective side frames 8 and pushes it onto the platform of the AGV body 1. The lifting component is started, the servo motor 7 works, and drives the threaded rod 701 to rotate, which drives the sliding block 703 and the V-shaped bracket 704 to rise smoothly along the limit rod 702, lifting the film roll 11 to the position of the highest support frame 6. Then, the insertion rod 10 is inserted into the mandrel of the film roll 11. The handwheel at the end of the rotating insertion rod 10 drives the positive and negative threaded rods 1002 to rotate. Since the two sections of the positive and negative threaded rods 1002 have opposite threads, they can simultaneously drive the two movable blocks 1006 to move towards or away from each other along the rod body 1001. When the movable blocks 1006 move, through the transmission of the connecting rod 1008, the two symmetrically arranged abutment blocks 1009 are pushed outward and upward from the through grooves on the side wall of the rod body 1001, tightly abutting against the inner wall of the membrane roll mandrel, flexibly locking and fixing the membrane roll from the inside. The contact surfaces of the abutment blocks 1009 and the membrane roll are provided with anti-slip flexible pads to prevent damage to the membrane roll. After the fixing insertion rod 10 is inserted into the membrane roll 11, the lifting assembly then descends and resets, placing the two ends of the internally fixed insertion rod 10 into the... Within the V-shaped slots 602 of the two support frames 6 on the left and right sides, flexible anti-slip pads within the V-shaped slots 602 prevent the insert rod 10 from rolling during transportation. Then, the micro motor 802 is controlled to reverse, driving the protective side frame 8 to flip upwards to a vertical position, forming a protective enclosure for the film rolls on both sides of the device. According to the received dispatch instructions, the AGV vehicle 1 automatically travels along the planned path, transporting the film roll 11 to the target unloading area or the designated location in the warehouse. Upon arrival at the destination, the protective side frame 8 is lowered again to form a ramp, and the lifting component is raised, slightly lifting the film roll 11 from the support frame 6. After the operator removes the insert rod 10 (by rotating the handwheel in the opposite direction to release the contact block 1009), the film roll 11 can be easily rolled off the ramp, completing the transportation operation.
