Description

Technical Field

[0001] This utility model relates to the field of film roll transportation technology, specifically a film roll transportation device. Background Technology

[0002] During the film production and processing, rolls of film need to be transported to different processing points for processing, such as slitting, coating, and settling. Therefore, transport devices are required multiple times.

[0003] Currently, in actual production processes, film rolls are repeatedly handled using simple mechanical equipment without precise alignment. This leads to misalignment between the film roll and the central steel roller, as well as between the film roll and the shelf. During transport, the film roll's center of gravity shifts slightly from the transport equipment's centerline, a shift that operators cannot visually detect. This results in uneven lateral forces on the transport device, potentially causing damage. Therefore, we propose a film roll transport device. Utility Model Content

[0004] The purpose of this utility model embodiment is to provide a film roll transport device that solves the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A film roll transport device includes a linear mechanism, which is driven and connected to a movable frame. The movable frame has two hooks symmetrically arranged at its bottom. Each hook is equipped with a distance measuring mechanism for measuring the distance between the hook and the end face of the film roll.

[0007] Furthermore, the ranging mechanism includes a mounting plate, one end of which is fixedly connected to a hook, and a ranging sensor is fixedly mounted on the mounting plate.

[0008] Furthermore, the ranging mechanism also includes a display, which is fixedly mounted on a movable frame and electrically connected to the two ranging sensors to display the values ​​measured by the two ranging sensors.

[0009] Furthermore, the two distance measuring sensors are symmetrically arranged with the center line of the moving frame as the axis of symmetry, and the distance between the two distance measuring sensors is not less than the distance between the two hooks.

[0010] Furthermore, the ranging mechanism includes a second mounting plate, one end of which is fixedly connected to a hook. The second mounting plate is rotatably connected to a movable plate via a rotating shaft. The opposite sides of the two movable plates can contact the film roll, and the opposite sides of the two movable plates are fixedly connected to an arc-shaped indicator plate.

[0011] Furthermore, a connecting rope is fixedly connected to the movable plate, and the end of the connecting rope away from the movable plate is fixedly connected to the hook.

[0012] Furthermore, the surface of the arc-shaped indicator plate is provided with a plurality of first indicator areas and a plurality of second indicator areas in an equiangular radial pattern. The second indicator areas are located on the outer periphery of the first indicator areas, and the number of second indicator areas is at least twice the number of first indicator areas.

[0013] Furthermore, the linear mechanism is a traveling crane.

[0014] By employing the above technical solution, this utility model provides a film roll transport device. It has at least the following beneficial effects: This film roll transport device, by installing distance measuring mechanisms on both hooks, can intuitively reflect the distance between the two hooks and the two end faces of the film roll. By comparing the two distances, the offset of the film roll can be quickly determined, facilitating timely adjustment of the film roll's position before and during lifting, thus avoiding damage to the transport device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example 1

[0023] Please see Figures 1-4 This embodiment provides a film roll transport device, including a linear mechanism 1. The linear mechanism 1 is driven and connected to a movable frame 2. The bottom of the movable frame 2 is provided with two hooks 3 for lifting the film roll. The linear mechanism 1 is a traveling crane, specifically including components for controlling the horizontal movement of the movable frame 2 and components for controlling the vertical movement of the movable frame 2, thereby realizing the transfer of the film roll.

[0024] In actual production, the film rolls are placed and moved by the equipment without precise calibration, which leads to misalignment between the film roll and the center steel roller, as well as between the film roll and the shelf. During hoisting, the center of gravity of the crane and the film roll is offset, which causes the transport device to be subjected to uneven lateral forces and damages the device.

[0025] To address this issue, in the film roll transport device of this embodiment, each of the two hooks 3 is equipped with a distance measuring mechanism. The two distance measuring mechanisms measure the distance between the two hooks 3 and the two end faces of the film roll. By comparing the two distances, the offset of the film roll can be quickly determined, making it convenient to adjust the position of the film roll in a timely manner before and during hoisting.

[0026] Specifically, the ranging mechanism includes a mounting plate 401, one end of which is fixedly connected to a hook 3, and a ranging sensor 402 is fixedly mounted on the mounting plate 401. Combined with... Figure 2 As shown, the two distance sensors 402 are positioned facing each other, respectively towards the two end faces of the film roll, to measure the distance between them and the end faces of the film roll. The two distance sensors 402 are symmetrically arranged about the center line of the moving frame 2 as the axis of symmetry. The axes of symmetry of the two hooks 3 coincide with the axes of symmetry of the two distance sensors 402, and the distance between the two distance sensors 402 is not less than the distance between the two hooks 3, to avoid contact between the distance sensors 402 and the ends of the film roll.

[0027] In addition, the ranging mechanism also includes a display 403, which is fixedly mounted on the movable frame 2 and can move with the movable frame 2. The display 403 is electrically connected to the two ranging sensors 402 to display the values ​​measured by the two ranging sensors 402. In use, the operator can observe the measurement results of the two ranging sensors 402 to determine the positional deviation of the film roll, and thus adjust the position of the film roll. Measuring distance using the ranging sensors 402 has the advantages of high speed and high accuracy.

[0028] Example 2

[0029] The difference between this embodiment and Embodiment 1 is that the ranging mechanism includes a second mounting plate 501, one end of which is fixedly connected to a hook 3. The second mounting plate 501 is rotatably connected to a movable plate 503 via a rotating shaft 502. The axis of the rotating shaft 502 is perpendicular to the axis of the film roll, and the movable plate 503 can swing relative to the end face of the film roll. During the swinging process, the opposite sides of the two movable plates 503 can contact the film roll. When the film roll is located precisely in the middle of the two hooks 3, the distance between the two movable plates 503 and the film roll is the same, therefore the angle between the two movable plates 503 and the hooks 3 is the same. When the position of the film roll shifts, the angle between the two movable plates 503 and the two hooks 3 will deviate, thereby indicating the center of gravity position of the film roll.

[0030] Furthermore, a connecting rope 505 is fixedly connected to the movable plate 503. The end of the connecting rope 505 away from the movable plate 503 is fixedly connected to the hook 3. The connecting rope 505 can limit the swing amplitude of the movable plate 503, so that the movable plate 503 always forms an acute angle with the hook 3. When the hook 3 is lowered to both sides of the film roll, one side of the movable plate 503 can automatically contact the surface of the film roll and be pushed to swing towards the hook 3. After the hook 3 is docked, the two movable plates 503 stop swinging. At this time, the offset of the film roll can be judged by the degree of inclination of the two movable plates 503.

[0031] For indication purposes, an arc-shaped indicator plate 504 is fixedly connected to the opposite side of each of the two movable plates 503. The arc-shaped indicator plate 504 is set through the hook 3, and multiple indicator areas are provided on the side of the arc-shaped indicator plate 504 to display the swing amplitude of the movable plate 503.

[0032] Combination Figure 4As shown, the surface of the arc-shaped indicator plate 504 is provided with multiple first indicator areas 506 and multiple second indicator areas 507 in an equiangular radial pattern. The second indicator areas 507 are located on the outer periphery of the first indicator areas 506, and the number of second indicator areas 507 is at least twice the number of first indicator areas 506. Therefore, the area of ​​the first indicator area 506 is larger than the area of ​​the second indicator area 507. Different markings can be set in each indicator area, including different colors, numbers, symbols, etc. By observing and comparing the positions of the indicator areas on the two arc-shaped indicator plates 504, the degree of offset of the film roll can be quickly determined.

[0033] The offset of the film roll is indicated by the movable plate 503 and the arc-shaped indicator plate 504. The structure is simple, the manufacturing cost is low, the installation is convenient, and it is not easily damaged during the movement of the vehicle. There is no need to adjust the accuracy of the indication during use, and the application is easy.
