Description

Technical Field

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

[0002] After the film rolls are cut into sections within the factory space using slitting equipment, the resulting rolls are horizontal and positioned at the same height as the slitting equipment. For these rolls, a conveyor table or conveyor belt extending into the packaging area is typically used. Taking a conveyor table as an example, the rolls are first packaged, then manually driven to roll along the conveyor table until they reach the lifting equipment in the packaging area. The rolls are then manually tilted at a certain angle (usually to an upright position to prepare for lifting), and the lifting equipment lifts them to the appropriate position. When the conveyor table is replaced with a conveyor belt, the characteristics of the conveyor belt allow for direct transport of the packaged rolls without the need for manual rolling.

[0003] However, both the conveyor platform and the conveyor belt serve as transfer carriers to move the material rolls. The erection of the material rolls after they have moved to the corresponding positions on the conveyor platform or conveyor belt is done manually. Since the material rolls are large in size and weight, this erection work usually requires the cooperation of multiple workers. However, the presence of the conveyor platform and conveyor belt makes it impossible for multiple workers to stand in a reasonable position, that is, they cannot cooperate well in the erection work.

[0004] To address this issue, we propose a tilting and dropping device for unloading materials. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the prior art by proposing a tilting and dropping device for unloading. This device realizes the transfer of the material roll from side support to end support by switching between two states of the flipping pallet. The dual change of the position and posture of the material roll is completed with only a single action, simplifying the operation.

[0006] To solve the above problems, this utility model provides the following technical solution:

[0007] A tilting and unloading device for unloading includes a frame located at the end of a transfer carrier. A tilting tray with an initial state and a working state is hinged on the frame. The tilting tray has a first support portion for supporting the side of the material roll and a second support portion for supporting the end face of the material roll. When the tilting tray switches from the initial state to the working state, the material roll is transferred from the first support portion to the second support portion, thereby changing the position of the material roll.

[0008] As a further embodiment of this utility model: a drive source is provided on the frame, and the execution end of the drive source is connected to the flip tray.

[0009] As a further embodiment of this utility model: a buffer cotton layer is provided on one side of the second support portion used to support the end face of the material roll.

[0010] As a further aspect of this utility model: in the initial state, the top surface of the first support is flush with the top surface of the transfer carrier.

[0011] As a further embodiment of this utility model, the device also includes a plurality of auxiliary rollers rotatably mounted on the first support portion, and the plurality of auxiliary rollers are evenly distributed along the length direction of the first support portion, with the rotation axis of the auxiliary rollers being perpendicular to the movement direction of the material roll.

[0012] As a further embodiment of this invention, the device also includes a limiting component disposed on the first support portion and used for radially limiting the material roll.

[0013] As a further embodiment of this utility model: the limiting component includes two sets of clamps, the bottom ends of which can be detached and installed on both sides of the first support, and the top ends of the two clamps are connected by a pin to achieve clamping and limiting of the material roll in the clamped state.

[0014] As a further embodiment of this utility model: a sliding groove is provided on the side of the first support part along its width direction, and a slider is fixedly provided at the bottom end of the clamp, and the slider can be inserted and slidably installed on the sliding groove.

[0015] As a further embodiment of this utility model: a groove is provided on the top of the first support portion, and a seat for supporting the side of the material roll is slidably installed in the groove along the direction of material roll movement. A threaded screw is rotatably provided in the groove and threadedly connected to the seat, and a power source connected to the threaded screw is provided on the frame.

[0016] As a further embodiment of this utility model: the top surface of the first support and / or the seat body for supporting the side of the material roll is designed with a V-shaped groove.

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

[0018] 1. Through the dual-state switching design of the flipping pallet, the posture change (horizontal → vertical) and position transfer (first pallet → second pallet) of the material roll are realized simultaneously with a single mechanical action, effectively changing the position state of the material roll and simplifying the operation process. At the same time, the integrated structure of the first pallet (supporting side) and the second pallet (supporting end face) simplifies the traditional unloading process and avoids secondary positioning operations.

[0019] 2. An additional drive source enables automated control of the flipping pallet, solving the force control problem of manually flipping heavy material coils. Simultaneously, the precise application of drive force ensures the stability and repeatability of the 90-degree flipping process, while avoiding the safety risks associated with operator intervention in the moving mechanism.

[0020] 3. The buffer cotton layer added to the end face of the second support section effectively attenuates the impact force of the material roll falling through the energy absorption characteristics of the soft material, prevents the end face from being scratched or deformed, and at the same time reduces the collision noise of the mechanism and extends the service life of the equipment.

[0021] 4. In the initial state, the top surface of the first support is strictly flush with the transfer carrier, eliminating the step difference during material roll slippage. This design ensures that the material roll is transferred without jamming, while fixing the relative position of the material roll axis and the flipping axis, providing a geometrically consistent basis for subsequent attitude conversion.

[0022] 5. The auxiliary rollers evenly distributed in the first support section convert the sliding friction of the material roll into low-resistance rolling friction, reducing the loss of pushing power. The layout of the roller axis perpendicular to the direction of material roll movement forms a natural guide track, forcing the material roll to fall accurately into the second support section along a predetermined path, eliminating the risk of deviation.

[0023] 6. The clamp-type limiting assembly achieves rapid opening and closing locking via a pin, completing radial rigid constraint on the coil before flipping. The double clamp opposing gripping mode can resist centrifugal force and inertial torque, ensuring the dynamic stability of high-ratio coil flipping.

[0024] 7. The design of the V-groove support surface provides a self-centering function, using the inclined surface to guide the material roll to automatically center and position it under gravity; on the other hand, it forms an anti-rolling structure, with its two inclined walls forming physical constraints to completely suppress circumferential displacement during the tumbling process.

[0038] 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.

[0039] A tilting and unloading device for unloading is installed at the end of a transfer carrier (such as a conveyor table or conveyor belt) a, and is used to support and tilt the material roll b at the end of the transfer carrier a (preferably in a vertical position) to facilitate lifting by the lifting equipment in the packaging area.

[0040] Example 1:

[0041] like Figures 1-3As shown, specifically, the device includes a frame 1 located at the end of the transfer carrier a. Two sets of bearing seats are symmetrically arranged on the frame 1, and a rotating shaft 13 is rotatably mounted on each of the two sets of bearing seats. A tilting tray 2 is mounted on the rotating shaft 13. This arrangement allows the tilting tray 2 to be hinged to the frame 1, enabling it to tilt at a corresponding angle when driven. The tilting tray 2 has two states on the frame 1: an initial state and a working state. Figure 1 The state shown is the initial state of the flip tray 2. Figure 2 The state shown is the working state of the flip tray 2.

[0042] Furthermore, the flip tray 2 is designed to have a first support portion 201 and a second support portion 202, which are arranged vertically, preferably in an L-shape. Figure 1 In the initial state shown, the first support 201 is in a horizontal position and the second support 202 is in a vertical position; Figure 2 In the indicated state, the first support 201 is in a vertical position, and the second support 202 is in a horizontal position. This change in state indicates that the flipping angle of the flipping pallet 2 is ninety degrees. When the material roll b is placed horizontally... Figure 1 After being placed on the first support portion 201 in the state shown, the flipping tray 2 transforms into... Figure 2 After reaching the indicated state, the material coil b becomes upright and is supported by the second support 202. Through the flipping action of this flipping pallet 2, the horizontal state of the material coil b can be quickly changed to an upright state, which facilitates subsequent lifting operations.

[0043] To ensure that the material roll b on the transfer carrier a can roll seamlessly onto the flipping pallet 2, preferably, the top surface of the transfer carrier a is flush with the top surface of the first support portion 201. This top view can be achieved by... Figure 3 To represent it.

[0044] Furthermore, since the material roll b has a large volume and weight, in order to ensure that the flipping pallet 2 can perform the flipping action smoothly and improve the flipping efficiency, this application provides a drive source (cylinder or hydraulic cylinder, etc.) 3 on the frame 1. The actuator of the drive source 3 is connected to the flipping pallet 2 to... Figure 1 Based on the layout and connection relationships shown, when the actuator of the drive source 3 retracts, it causes the flip plate 2 to flip clockwise, transforming it into... Figure 2 The state shown; when it is in Figure 2 When the extension action is performed in the state shown, the flip plate 2 can be flipped counterclockwise.

[0045] exist Figure 1 The state shown Figure 2During the state switching process shown, the force-bearing surface of the material roll b also changes from the side to the end face. In order to prevent the end face of the material roll b from being damaged during the transition, this application provides a buffer cotton layer 4 on the second support 202 to support the end face of the material roll b. The setting of this buffer cotton layer 4 not only provides buffer protection for the end face of the material roll b, but also reduces the collision with the second support 202 and reduces the impact on the drive source 3.

[0046] Of course, to further prevent damage to the b-end face of the coil, a pushing operation can be performed before the flipping action. Figure 1 Taking the state shown as an example, push the material roll b from left to right until the right end face of the material roll b contacts the buffer cotton layer 4, and then make the flipping tray 2 flip. During this flipping process, the end face of the material roll b will always be in contact with the buffer cotton layer 4.

[0047] Example 2:

[0048] like Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that, based on Embodiment 1, this embodiment further includes multiple assist rollers 5 on the first support portion 201. These assist rollers 5 are evenly distributed along the length of the first support portion 201, and their rotation axes are perpendicular to the direction of movement of the material roll b. After the material roll b on the transfer carrier a is pushed onto the multiple assist rollers 5 on the first support portion 201, the material roll b can be further pushed along the length of the first support portion 201. Figure 5 As shown, the material roll b is pushed from left to right. Under the action of multiple assist rollers 5, the movement of the material roll b can be changed from the original sliding friction to rolling friction, which reduces the pushing resistance until the right end face of the material roll b comes into contact with the buffer cotton layer 4.

[0049] Example 3:

[0050] In the material roll b by Figure 1 The initial state shown Figure 2 During the transition to the working state shown, that is, during the 90-degree rotation, the center of gravity of the material roll b undergoes a significant change. When initially placed horizontally, the center of gravity is above the first support 201; during rotation, the center of gravity shifts until it finally stands vertically above the second support 202. During this process, if there is no limiting protection for the material roll b, the material roll b is prone to rolling or slipping, especially if the surface of the material roll b is smooth or if it is initially slightly offset.

[0051] Therefore, the difference between this embodiment and any of the above embodiments is that, as Figure 6As shown, in this embodiment, a limiting component is detachably provided on the first support portion 201 to limit and fix the material roll b placed on the first support portion 201. Specifically, a sliding groove 8 is provided on the side of the first support portion 201 along its width direction. The limiting component includes two sets of clamps 6, and a slider 9 is fixedly provided at the bottom end of the clamp 6. The slider 9 can be inserted and slidably installed on the sliding groove 8. The clamps 6 are installed on the first support portion 201 in this way. The installation process can be carried out sequentially from... Figures 7 to 8 Then Figure 9 To indicate, Figure 7 and Figure 8 The arrows indicate the direction of movement of slider 9. Of course, the installation method where the bottom ends of both clamps 6 can be detached and installed on both sides of the first support 201 is not limited to this sliding method; it can also be achieved through existing methods such as snap-fit ​​or fastening. Furthermore, the top ends of the two clamps 6 are connected by pins 7 to achieve clamping and limiting of the material coil b in the clamped state. This state can be achieved by… Figure 6 To be indicated. Further details will follow. Figure 6 When the material roll b in the shown state rotates 90 degrees clockwise, the two clamps 6 limit the material roll b, which can stably restrict the material roll b and prevent it from rolling or shifting.

[0052] Example 4:

[0053] Because the material roll b is both heavy and bulky, even with the assistance roller 5 used in Embodiment 2 to aid its axial movement, it still requires considerable effort from technicians to move the material roll b. Therefore, as... Figure 10 As shown, the difference between this embodiment and any of the above embodiments is that a groove is provided at the top of the first support 201. A seat 10 for supporting the side of the material roll b is slidably installed in the groove along the movement direction of the material roll b. A threaded screw 11 threadedly connected to the seat 10 is rotatably arranged in the groove, and a power source (drive motor, etc.) 12 is provided on the frame 1 and driven by the threaded screw 11. The power source 12 can drive the threaded screw 11 to rotate, and under the limiting action of the groove, the seat 10 can move along the length direction of the groove. When the material roll b is placed on the seat 10, the seat 10 can drive the material roll b to move towards the buffer cotton layer 4. This embodiment realizes the adjustment of the axial position of the material roll b in an automated manner, which facilitates the stable operation of subsequent flipping actions.

[0054] Preferably, in order to ensure that the material roll b is placed stably on the seat 10 and does not shift left or right during movement, therefore, as Figure 11As shown, in this embodiment, the top surface of the base 10 is designed with a V-groove, so that the material roll b placed on it can be restrained by the side walls of the V-groove and will not wobble. Of course, this V-groove design is not limited to use in this embodiment, and can also be applied to other embodiments, such as in Embodiment 1, as... Figure 4 As shown, the V-shaped groove is located on the top surface of the first support 201.

[0055] 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 claims of the present invention should still fall within the patent coverage of the present invention.
