Description

Technical Field

[0001] This utility model relates to the field of thin film production technology, and specifically to an intermediate transfer system. Background Technology

[0002] Considering practical needs, film production workshops are often formed by arranging multiple independent workshops sequentially. For large-scale film production lines, the traditional method of transporting materials by conveyor machinery has been abandoned between adjacent workshops. Instead, communication is achieved directly through walls with roller shutters, and materials are transported directly through these shutters. Taking actual production as an example, the film stretching and slitting processes are carried out in two separate production areas. The production area where the stretching process takes place is defined as the stretching area, and the production area where the slitting process takes place is defined as the slitting area. Due to process requirements, a curing process is needed after the film stretching process. Therefore, a curing area is usually set up between the stretching area and the slitting area. After the rolls in the stretching area are made, they are usually transferred to the curing area for temporary storage and curing before being transported to the slitting area for slitting and rewinding using the slitting machine.

[0003] For ease of understanding, Figure 1 This diagram illustrates a material roll structure in the prior art, where 'a' represents a steel core and 'b' represents a multi-layered film wound onto the steel core. On one hand, due to the long length and heavy weight of the material roll, a front-end lifting device is typically used in the curing area to lift the cured roll. It is first placed on the curing area side of the roller shutter door, and then lifted to the slitting machine entrance by a rear-end lifting device located on the slitting area side. This operation is clearly cumbersome. On the other hand, for material rolls that have undergone corona treatment on the outside, depending on customer requirements, the corona-treated side after slitting and rewinding needs to become the outer or inner side of the finished roll. Therefore, the roll's exit direction needs to be determined before lifting and transporting it to the slitting machine. Generally, adjusting the roll's exit direction involves the front or rear-end lifting device lifting the roll beforehand, and then manually rotating it in the air to adjust the exit direction. Obviously, this high-altitude direct rotation operation method carries extremely high operational risks and adversely affects the safety of surrounding equipment and even workers. Therefore, this issue urgently needs to be addressed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by proposing an intermediate transfer system. This system provides a simple and compact transfer structure for transporting material rolls in adjacent factory buildings with partitions, thereby achieving the needs for safe turning and convenient transfer of material rolls between adjacent factory buildings.

[0005] To solve the above problems, this utility model provides the following technical solution:

[0006] An intermediate transfer system includes a rotating assembly and a transfer bracket arranged sequentially along the direction of material roll travel, wherein:

[0007] The rotating component is used to support the material roll and can drive the material roll to rotate in the horizontal direction to change the output direction of the material roll;

[0008] The adapter bracket has a feeding end located in the curing area and a discharging end located in the slitting area; it also includes a pusher arm movably mounted on the adapter bracket. The actuator end of the pusher arm is normally located below the working surface of the adapter bracket, and can be flipped to a position above the feeding end when in operation. When the material roll is placed at the feeding end, the actuator end of the pusher arm obliquely abuts against the side of the steel core of the material roll and generates a corresponding abutting force, causing the material roll to move from static to dynamic along the working surface.

[0009] As a further embodiment of this utility model: the booster arm is L-shaped, and its short end constitutes the actuating end; the long end of the booster arm is rotatably mounted on the first rotating shaft at the feeding end, and is driven by the first driving source to generate the flipping action of the booster arm.

[0010] As a further embodiment of this utility model: the feed end is provided with a stop for blocking the steel coil core, and the side of the stop that contacts the steel coil core is arc-shaped; the arc-shaped side of the stop and the horizontal rolling surface on the adapter bracket that allows the steel coil core to roll together constitute the working surface, and the execution end of the booster arm under normal conditions is higher than the horizontal rolling surface and flush with the arc-shaped side of the stop.

[0011] As a further embodiment of this utility model: a second rotating shaft is provided at the discharge end, and a bridging bridge plate is installed on the second rotating shaft. The bridging bridge plate can overlap the frame of the slitting machine as the second rotating shaft rotates to form a transition channel for rolling steel coil cores.

[0012] As a further embodiment of this utility model: a second drive source is movably disposed on the adapter bracket, and the execution end of the second drive source is provided with a second connecting arm for connecting with the second rotating shaft.

[0013] As a further embodiment of this utility model: the rotating assembly includes a support seat rotatably disposed on the side of the feed end, and the rotation axis of the support seat is arranged in the vertical direction, and a roll support platform for supporting the material roll is provided on the support seat.

[0014] As a further embodiment of this utility model: the rotating assembly also includes an annular ground rail located beside the feed end, and the axis of the annular ground rail coincides with the rotation axis of the support base. Several auxiliary wheels are provided at the bottom of the roll tray platform, and the auxiliary wheels are located in the track of the annular ground rail.

[0015] As a further embodiment of this utility model: the top surface of the roll tray platform is arranged in an arc shape, and a cushioning cotton layer is fixedly provided on the top surface.

[0016] As a further embodiment of this invention, the auxiliary wheel is configured as a universal wheel and has a self-locking structure.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Unlike the traditional method of transporting materials between independent workshops that are far apart, the material transport environment of adjacent workshops with partitioned walls requires fast and efficient material transport. However, in actual operation, the presence of existing production equipment in the workshop, such as a large number of curing supports in the curing area and slitting machines in the slitting area, will compress the workshop space, making it impossible to place highly complex and bulky transfer equipment.

[0019] Therefore, this application provides a simple and compact transfer structure. Firstly, its simple design and compact size facilitate actual production and maintenance, and it is easier to place it on the adjacent wall of two workshops to meet the material roll transfer needs of the two workshops. Secondly, due to the presence of human labor, the pushing and transfer of material rolls can be done manually. What actually needs to be solved is the huge friction force that needs to be overcome when the large mass material roll initially rolls.

[0020] 2. Therefore, this application clearly defines functional areas at the feed and discharge ends of the transfer bracket, making the steel coil core transfer process clear and controllable. The movable setting of the booster arm and the position design of its execution end can precisely apply inclined thrust, decomposing the force into vertical and horizontal components. This reduces the frictional resistance between the steel coil core and the contact surface while providing horizontal driving force, achieving efficient and labor-saving rolling conveying. The pushing action of this booster arm can transform the steel coil core from a stationary state to a moving state, resulting in a substantial change in the state of the steel coil core from "static" to "dynamic." At the same time, the design of the rotating component further enhances the flexibility of the system, allowing adjustment of the coil output direction to adapt to different slitting requirements.

[0021] 3. The L-shaped support arm features a compact structure and superior mechanical performance, effectively transmitting driving force. Through the cooperation of the first rotating shaft and the first drive source, precise tilting control of the support arm is achieved, ensuring the actuator can quickly reach the working position when needed. The design of the first connecting arm enhances the stability of power transmission, making the booster operation more reliable and suitable for high-intensity industrial scenarios.

[0022] 4. The combination of the second rotating shaft and the bridging bridge plate forms an adjustable transition channel, which flexibly connects to the slitting machine frame through rotation, achieving seamless transfer of steel coil cores. This design solves the problem of mismatched height or position between equipment, reduces the risk of collisions during material transfer, and improves the continuity of the production line.

[0023] 5. The second drive source controls the rotation of the second rotating shaft via the second connecting arm, enabling the automated deployment and retraction of the bridge plate. This structure, together with the first drive source, forms a collaborative system, ensuring bidirectional coordination during the transfer process, further reducing manual operation intensity and improving system response speed.

[0024] 6. The support base rotates along the vertical axis, driving the coil support platform to rotate and achieve precise angle adjustment of the material coil. The rotary structure is simple, reliable, and easy to maintain, and the coil support platform directly supports the material coil, ensuring uniform load distribution.

[0025] 7. The combination of the circular ground rail and auxiliary wheels makes the support base rotate more smoothly, suitable for carrying heavy material coils. The rail guide structure reduces the risk of swaying during rotation and improves positioning accuracy, while the auxiliary wheels reduce frictional resistance and extend the equipment's lifespan.

[0026] 8. The arc-shaped top surface of the roll support platform conforms to the shape of the roll, reducing stress concentration; the buffer cotton layer further absorbs vibration and impact, protecting the surface quality of the roll. Attached Figure Description

[0035] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Example 1:

[0037] like Figures 4-6 As shown, an intermediate transfer system connects the curing area and the slitting area, enabling smooth and convenient transport of material rolls from the curing area to the slitting area. This transfer system provides excellent transport functionality, eliminating the need for sufficiently large lateral and longitudinal spaces in the slitting area, and also avoiding the requirement for the curing and slitting areas to be arranged adjacently. Specifically, the system includes the following:

[0038] (1) Adapter bracket 1, the two ends of the adapter bracket 1 are defined as feed end 101 and discharge end 102 respectively. Feed end 101 is placed in the curing area and discharge end 102 is placed in the slitting area. Feed end 101 is provided with a stop part 9, and one side of the stop part 9 is arc-shaped. In use, the material roll in the curing area can be lifted to the feed end 101 by the lifting equipment. At this time, the steel core a of the material roll will fall to the top of the feed end 101 and be blocked by the arc side of the stop part 9, so that the steel core a can be kept stable. Then the steel core a is rolled and conveyed to the discharge end 102, and finally conveyed to the slitting machine c for slitting and rewinding, thus completing the entire transfer work. It should be noted that the design length of this adapter bracket 1 can be adapted to the distance between the curing area and the cutting area, and this adapter bracket 1 serves to directly connect the two areas without forcing the two areas to be adjacent, thus adapting to the spatial layout of different types of factory areas.

[0039] (2) A booster arm 2 has a first rotating shaft 3 rotatably mounted at the feed end 101. The booster arm 2 is mounted on the first rotating shaft 3, and the rotation of the first rotating shaft 3 can drive the booster arm 2 to swing. Simultaneously, a first drive source 4 is mounted on the adapter bracket 1, and the execution end of the first drive source 4 is connected to a first connecting arm 5. The first connecting arm 5 is connected to the first rotating shaft 3. This connection layout can be configured by… Figure 4 The booster arm 2 has an L-shaped layout, with one end connected to the first rotating shaft 3 and the other end serving as the actuator. When the first drive source 4 retracts, the first connecting arm 5 drives the booster arm 2 to rotate clockwise around the first rotating shaft 3. When a coil is placed on top of the feed end 101, and the steel core a of the coil is within the movement path of the booster arm 2, the clockwise movement of the booster arm 2 applies an initial boosting force to the steel core a, causing the steel core a to change from a stationary state to a rolling state.

[0040] Furthermore, in this embodiment, the booster arm 2 has the following two designs for the boosting direction of the steel coil a:

[0041] (1) The direction of the push is horizontal: Under this design, when the execution end of the push arm 2 comes into contact with the steel core a, the direction of the force applied by the push arm 2 to the steel core a is horizontal, and this horizontal direction is from the feed end 101 to the discharge end 102.

[0042] (2) The booster direction is tilted, and the tilt direction is from the lower left to the upper right: This design layout can be achieved by... Figure 4 The state shown is represented by the fact that the actuating end of the push arm 2 abuts against the side of the steel coil core a. When the first drive source 4 is working, the push arm 2 in this state can generate a pushing force. This pushing force can be decomposed into two components: vertically upward and horizontally to the right. The horizontally to the right component can overcome the frictional resistance between the steel coil core a and the feed end 101, giving the steel coil core a a tendency to roll to the right. The vertically upward component will partially offset the weight of the coil, thereby reducing the support force of the feed end 101 on the coil.

[0043] Example 2:

[0044] To enhance protection of the slitting area, the inlet and outlet near the discharge end 102 are controlled by a roller shutter d. When the material roll has not reached the discharge end 102, the roller shutter d is closed, effectively preventing insects from entering the slitting area; when the material roll reaches the discharge end 102, the roller shutter d is open, allowing it to be transferred to the frame of the slitting machine c via the discharge end 102.

[0045] In the design of the roller shutter door d, if it needs to be combined with the above-mentioned transfer system, then in this embodiment, a second rotating shaft 6 is rotatably provided at the feeding end 101. A crossover bridge plate 15 is installed on the second rotating shaft 6. The rotation of the second rotating shaft 6 can drive the crossover bridge plate 15 to move accordingly. A second driving source 7 is movably provided on the transfer bracket 1. A second connecting arm 8 is provided at the execution end of the second driving source 7. The second connecting arm 8 is connected to the second rotating shaft 6. Therefore, by starting the second driving source 7, the crossover bridge plate 15 can be driven to perform corresponding swinging movements.

[0046] Figure 4 In the indicated state, when the second drive source 7 retracts, it can drive the bridging plate 15 to rotate clockwise until the bridging plate 15 rotates to a horizontal position and overlaps the frame of the slitting machine c. This state can be achieved by... Figure 5 To represent this. At this time, Figure 4 The material roll in this state can roll horizontally to the right sequentially from the feed end 101, the discharge end 102, and the bridging plate 15 onto the slitting machine c. When Figure 5 After the slitting machine c completes the slitting and rewinding process, only the steel coil core a remains. At this point, the roller shutter d can be opened to detach the steel coil core a from the slitting machine c and transfer it to the middle position of the transfer bracket 1 via the bridging bridge 15. Then, the roller shutter d is closed, and the steel coil core a is lifted upwards using lifting equipment. This state can be achieved by... Figure 6 To represent it.

[0047] The design of the first driving source 4 and the second driving source 7 in Embodiment 1 and Embodiment 2 can be any linear driving component in the prior art, such as a cylinder or a hydraulic cylinder. To avoid cumbersome writing, this article will not elaborate further.

[0048] Example 3:

[0049] The difference between this embodiment and any of the above embodiments is that this embodiment adds a set of rotating components, such as... Figures 2-3 As shown, the rotating component is located on the side of the feed end 101. The rotating component is used to support the material roll and can drive the material roll to rotate in the horizontal direction, so that the output direction of the material roll can be easily adjusted so that the corona side on it will become the designated outer or inner side in the subsequent rewinding process.

[0050] Specifically, the rotating assembly includes a support base 10 mounted on the ground. The support base 10 is designed to rotate, and a roll-up platform 11 is mounted on top of the support base 10. The top surface of the roll-up platform 11 is arc-shaped to accommodate the material roll. A cushioning layer 14 can be fixedly mounted on this top surface to cushion and protect the material roll during connection. Due to the rotational design of the support base 10, the roll-up platform 11 can drive the material roll to rotate horizontally. Alternatively, the support base 10 can be fixed, with the connection between the roll-up platform 11 and the top of the support base 10 being rotational. Furthermore, the support base 10 can be a telescopic structure to allow for height adjustment of the roll-up platform 11.

[0051] Under normal circumstances, the tray platform 11 is Figure 3 As shown in the layout, the lifting equipment places the material roll on the roll support platform 11. If the roll exit direction on the roll support platform 11 in this state is opposite to the required direction, the roll support platform 11 can be rotated 180 degrees to adjust the roll exit direction and meet the position requirements of the corona side during subsequent slitting and rewinding by the slitting machine c. Figure 2 This can be represented as a state where the rotation angle of the tray platform 11 is 90 degrees during the process of rotating 180 degrees.

[0052] To ensure smooth and stable rotation of the coil support platform 11 while supporting the coil, this embodiment also includes an annular ground rail 12. The annular ground rail 12 is located on the ground next to the feed end 101, and the rotation axis of the support base 10 coincides with the axis of the annular ground rail 12. At the same time, several sets of auxiliary wheels 13 are provided at the bottom of the coil support platform 11. The auxiliary wheels 13 are located in the track of the annular ground rail 12. During the rotation of the coil support platform 11, the auxiliary wheels 13 will travel in the track of the annular ground rail 12, playing a role in assisting support and assisting rotation.

[0053] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the present invention should still fall within the patent coverage of the present invention.
