Description

Technical Field

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

[0002] Currently, many devices or raw materials require coating for protection before leaving the factory. For example, Chinese Patent Publication No. CN221416763U, published on July 26, 2024, discloses a utility model invention entitled "A Protective Film Application Device." This application discloses a device that can cut film rolls into sheets and then wrap articles. However, this device can only coat block materials and cannot coat cylindrical (or cylindrical) materials (including but not limited to rolls). Utility Model Content

[0003] The purpose of this invention is to provide a roll wrapping device capable of wrapping cylindrical rolls.

[0004] The technical solution of this utility model is:

[0005] A roll wrapping device, comprising:

[0006] A film unwinding device includes a release frame and a film roll rotatably mounted on the release frame;

[0007] The base platform and the release frame are located on one side of the base platform. The base platform includes a support plane and a negative pressure cavity. The support plane is provided with several air intake holes that communicate with the negative pressure cavity. The cover film released by the cover film roll can be laid on the support plane.

[0008] The gantry robot includes two grippers for holding the rolled material. The gantry robot can drive the two grippers to move up, down, and translate synchronously. After the two grippers clamp both ends of the rolled material, the rolled material can rotate on the grippers. The specific operation of one type of rolled material wrapping device in this solution is as follows:

[0009] The coiled material is gripped by two jaws on the gantry manipulator (the coiled material can rotate on the two jaws after the two jaws grip both ends).

[0010] The film unwinding device releases the film by rotating the film roll, and the released film is laid on the support plane. Since the air intake on the support plane is connected to the negative pressure cavity, the film will be adsorbed onto the support plane.

[0011] After the coating film is adsorbed onto the supporting surface, it is cut into individual sheets. Then, adhesive is applied to the edges of both ends of the coating film adsorbed onto the supporting surface. Next, the gantry robot lowers the roll of material through two grippers, so that the roll contacts the adhesive-coated edges of the coating film on the supporting surface. Then, the gantry robot moves the roll of material horizontally through two grippers. During this process, the roll of material rotates relative to the grippers, so that the sheet-like coating film on the supporting surface wraps around the outer circumference of the roll of material, thereby realizing the coating operation of the cylindrical roll of material.

[0012] Preferably, the system also includes a film cutting mechanism, which comprises:

[0013] Suspension brackets are installed on the base platform;

[0014] The suspension seat is slidably mounted on the suspension bracket, and a cutting blade is installed on the suspension seat, with the cutting blade located above the supporting plane;

[0015] The suspension drive mechanism moves the suspension seat, causing the cutting blade to move with the suspension seat to cut the film released from the film roll. Thus, when the film released from the film roll is laid on the supporting plane, the film cutting mechanism can automatically cut the film into individual sheets. Specifically, after the film is adsorbed onto the supporting plane, the suspension drive mechanism moves the suspension seat, causing the cutting blade to move with the suspension seat. The cutting blade cuts the film adsorbed on the supporting plane, cutting it into individual sheets.

[0016] Preferably, it also includes a first pressing mechanism, which comprises:

[0017] A pressure bar is located above the supporting plane, and the pressure bar is parallel to the supporting plane. The cutting blade is close to the pressure bar, and the direction of movement of the suspension seat is parallel to the pressure bar.

[0018] The first lifting actuator drives the pressure rod to rise and fall, pressing the film released from the film roll onto the supporting plane. The function of the first film pressing mechanism is to press the film onto the supporting plane, facilitating the film cutting mechanism to cut the film. Specifically, after the film is adsorbed onto the supporting plane, the first lifting actuator drives the pressure rod to fall, pressing the film onto the supporting plane; then, the suspension seat drive mechanism drives the suspension seat to move, causing the cutting blade to move with the suspension seat, cutting the film adsorbed on the supporting plane. This facilitates the film cutting mechanism and prevents the film from shifting or wrinkling during the cutting process.

[0019] Preferably, a second pressing mechanism is also included, which comprises:

[0020] The pressure plate is parallel to the supporting plane and parallel to the pressure rod, and the cutting blade is located between the pressure plate and the pressure rod.

[0021] The second lifting actuator drives the pressure plate to rise and fall, pressing the film released from the film roll onto the supporting plane. The function of the second film pressing mechanism is to cooperate with the first film pressing mechanism to press the film onto the supporting plane, facilitating the film cutting mechanism's cutting of the film and further preventing the film from shifting or wrinkling during the cutting process. Specifically, after the film is adsorbed onto the supporting plane, the first lifting actuator drives the pressure rod to descend, pressing the film onto the supporting plane; the second lifting actuator drives the pressure plate to descend, pressing the film released from the film roll onto the supporting plane; then the suspension seat drive mechanism drives the suspension seat to move, causing the cutting blade to move along with the suspension seat. The cutting blade performs the cutting operation on the film in the space between the pressure rod and the pressure plate, thus facilitating the film cutting mechanism's cutting of the film and preventing the film from shifting or wrinkling during the cutting process.

[0022] Preferably, the system also includes a film-laying mechanism, which comprises:

[0023] The movable frame is slidably mounted on the base platform. The sliding direction of the movable frame is perpendicular to the rotation axis of the coating film roll. The movable frame is equipped with several clamps for holding the coating film, and the clamps are located above the support plane.

[0024] A moving frame drive mechanism drives the moving frame to move. Thus, when it is necessary to release the coating film from the coating film roll, one end of the coating film is clamped by clamps, and then the coating film is released from the coating film roll. At the same time, the moving frame drive mechanism drives the moving frame to move the clamps, thereby causing the coating film to spread out on the supporting plane and be adsorbed onto the supporting plane through the air suction hole.

[0025] Preferably, the film-laying mechanism further includes two parallel guide rails perpendicular to the rotation axis of the film roll. The moving frame includes two movable seats corresponding to the guide rails and a connecting beam connecting the two movable seats. The connecting beam is parallel to the rotation axis of the film roll, and the clamps are mounted on the connecting beam. This facilitates the installation and arrangement of the clamps and ensures that the moving frame can move smoothly.

[0026] Preferably, each gripper is provided with a connecting post, and the connecting posts on the two grippers are coaxially arranged and parallel to the supporting plane. The function of the connecting posts on the two grippers is to allow the connecting posts on the two grippers to insert into the shaft holes at both ends of the coil when the two grippers hold the ends of the coil, so that the coil can rotate relative to the connecting posts. The axis of rotation of the coil is the axis of the two connecting posts.

[0027] Preferably, the system also includes an air pump, the air pump's suction port of which is connected to the negative pressure cavity. In this way, the air pump can be used to evacuate the negative pressure cavity, creating a negative pressure state that allows the coating film to be adhered to the supporting surface.

[0028] Preferably, the film unwinding device also includes a support frame located on one side of the base platform, a release frame mounted on the support frame, and guide rollers mounted on the support frame, the guide rollers being parallel to the rotation axis of the film roll. The guide rollers are used to guide and clamp the film released from the film roll.

[0029] Preferably, the gantry robot can drive two grippers to move along the XYZ axis. When the two grippers clamp the roll, the rotation axis of the roll is perpendicular to the X-axis, and the rotation axis of the coating roll is parallel to the X-axis.

[0030] After the two grippers clamp the roll of material, the gantry robot drives the roll to move along the X-axis to achieve the wrapping operation. This facilitates the arrangement of the wrapping roll and the roll held by the two grippers in the wrapping unwinding device, making it easier for the gantry robot to grasp the roll and drive it to move along the X-axis to achieve the wrapping operation. It also avoids collisions with the wrapping roll or other components during the wrapping operation.

[0031] The beneficial effect of this utility model is that it can perform coating operations on cylindrical roll materials. Attached Figure Description

[0056] Specific Implementation Example 1, such as Figure 1 , Figure 2 , Figure 3 As shown, a film wrapping device includes: a film unwinding device, a base platform 3, and a gantry robot 16. The film unwinding device includes a support frame 2, a release frame 1, and a film roll 4 rotatably mounted on the release frame 1. The release frame 1 is mounted on the support frame 2, and the support frame 2 and the release frame 1 are located on one side of the base platform 3. The specific method and structure of the film unwinding device are prior art, and its specific structure is not the inventive point of this application. Therefore, this application will not elaborate on the specific method and structure of the film unwinding device and other conventional technical means.

[0057] The base 3 includes a supporting plane 301 and a negative pressure cavity 302. The supporting plane 301 is provided with several air intake holes 3011 that communicate with the negative pressure cavity 302. The covering film released from the covering film roll 4 can be laid on the supporting plane 301.

[0058] The gantry robot 16 includes two grippers 1601 for holding the coil 17. The gantry robot 16 can drive the two grippers 1601 to move up and down and translate synchronously. After the two grippers 1601 clamp the two ends of the coil 17, the coil 17 can rotate on the two grippers 1601.

[0059] The specific operation of a roll wrapping device in this embodiment is as follows:

[0060] The coil 17 is gripped by two jaws 1601 on the gantry robot 16 (after the two jaws 1601 grip both ends of the coil 17, the coil 17 can rotate on the two jaws 1601).

[0061] The unwinding device releases the coating film by rotating the coating film roll 4, and the released coating film is laid on the support plane 301. Since the air suction hole 3011 on the support plane 301 is in communication with the negative pressure cavity 302, the coating film will be adsorbed onto the support plane 301.

[0062] After the coating film is adsorbed onto the support plane 301, the coating film is cut into individual sheets (in actual operation, a cutting mechanism can be used to automatically cut the coating film; or the coating film can be cut manually). Then, glue is applied to the two ends of the coating film adsorbed onto the support plane 301. Next, the gantry robot 16 drives the roll 17 to descend through two grippers 1601, so that the roll 17 contacts the glued end of the coating film on the support plane 301. Then, the gantry robot 16 drives the roll 17 to translate through two grippers 1601. During this process, the roll 17 rotates relative to the grippers 1601, so that the sheet-like coating film on the support plane 301 is wrapped around the outer circumference of the roll 17, thereby realizing the coating operation of the cylindrical roll 17 (the material of the coating film on the coating film roll 4 can be selected according to actual needs, such as plastic film, kraft paper or other materials).

[0063] Specific embodiment two, such as Figure 1 , Figure 2 , Figure 3 As shown, a film wrapping device includes: a film unwinding device, a base platform 3, an air pump, and a gantry robot 16. The film unwinding device includes a support frame 2, a release frame 1, and a film roll 4 rotatably mounted on the release frame 1. The release frame 1 is mounted on the support frame 2, and the support frame 2 and the release frame 1 are located on one side of the base platform 3. The specific method and structure of the film unwinding device are prior art, and its specific structure is not the inventive point of this application. Therefore, this application will not elaborate on the specific method and structure of the film unwinding device and other conventional technical means.

[0064] The base 3 includes a supporting plane 301 and a negative pressure cavity 302. The supporting plane 301 has several suction holes 3011 communicating with the negative pressure cavity 302. The suction port of the vacuum pump is connected to the negative pressure cavity 302. In this embodiment, the supporting plane 301 is horizontally distributed, and the negative pressure cavity 302 is located below the supporting plane 301. The covering film released from the covering film roll 4 can be laid on the supporting plane 301. The vacuum pump evacuates the negative pressure cavity 302, creating a negative pressure state so that the covering film is adsorbed onto the supporting plane 301.

[0065] The gantry robot 16 includes two grippers 1601 for holding the coil 17. The gantry robot 16 can drive the two grippers 1601 to move up and down and translate synchronously. After the two grippers 1601 clamp the two ends of the coil 17, the coil 17 can rotate on the two grippers 1601.

[0066] The specific operation of a roll wrapping device in this embodiment is as follows:

[0067] The coil 17 is gripped by two jaws 1601 on the gantry robot 16 (after the two jaws 1601 grip both ends of the coil 17, the coil 17 can rotate on the two jaws 1601).

[0068] The film unwinding device releases the film by rotating the film roll 4, and the released film is laid on the support plane 301. After the film is laid on the support plane 301, the vacuum pump starts to evacuate the negative pressure cavity 302, putting the negative pressure cavity 302 into a negative pressure state. Since the suction hole 3011 on the support plane 301 is in communication with the negative pressure cavity 302, the film will be adsorbed onto the support plane 301.

[0069] After the coating film is adsorbed onto the support plane 301, it is cut into individual sheets. Then, adhesive is applied to the edges of both ends of the coating film adsorbed onto the support plane 301. Next, the gantry robot 16 lowers the roll 17 through two grippers 1601, so that the roll 17 contacts the adhesive-coated edges of the coating film on the support plane 301. Then, the gantry robot 16 moves the roll 17 horizontally through the two grippers 1601. During this process, the roll 17 rotates relative to the grippers 1601, so that the sheet-like coating film on the support plane 301 wraps around the outer circumference of the roll 17, thereby realizing the coating operation on the cylindrical roll 17 (the material of the coating film on the coating film roll 4 can be selected according to actual needs, such as plastic film, kraft paper, or other materials).

[0070] Specifically, the two grippers 1601 of the gantry robot 16 can open or close to each other, and the distance between the two grippers 1601 can be adjusted as needed to grip rolls 17 of different lengths to meet the wrapping requirements of rolls 17 of different lengths. Similarly, different lengths of wrapping film rolls 4 can be installed on the release frame 1 of the wrapping film unwinding device as needed to match the length of the wrapping film with the length of the roll 17.

[0071] In this embodiment, as Figure 1 , Figure 2 As shown, each gripper 1601 is provided with a docking post 1602. The docking posts 1602 on the two grippers 1601 are coaxially arranged and parallel to the supporting plane 301. In this embodiment, the docking post 1602 is cylindrical. The function of the docking posts 1602 on the two grippers 1601 is to allow the two grippers 1601 to insert into the shaft holes at both ends of the coil 17 when the two grippers 1601 are holding the two ends of the coil 17, so that the coil 17 can rotate relative to the docking posts 1602. The axis of rotation of the coil 17 is the axis of the two docking posts 1602.

[0072] In this embodiment, as Figure 3 As shown, the support frame 2 is also equipped with a guide roller 5, which is parallel to the rotation axis of the coating film roll 4. The guide roller 5 is used to guide and clamp the coating film released from the coating film roll 4.

[0073] Furthermore, such as Figure 3 , Figure 4As shown, a roll wrapping device further includes a wrapping film cutting mechanism. The wrapping film cutting mechanism includes a suspension bracket 6, a suspension seat 7, and a suspension seat drive mechanism. The suspension bracket 6 is mounted on a base platform 3. The suspension seat 7 is slidably mounted on the suspension bracket 6, and the sliding direction of the suspension seat 7 is parallel to the supporting plane 301. A cutting blade 10 for cutting the wrapping film is mounted on the suspension seat 7, and the cutting blade 10 is located above the supporting plane 301. The suspension seat drive mechanism drives the suspension seat 7 to move, so that the cutting blade 10 moves with the suspension seat 7 to cut the wrapping film released from the wrapping film roll 4. The suspension seat drive mechanism is a linear module, an electric cylinder, or an electric lead screw drive mechanism. In this embodiment, the suspension seat drive mechanism includes a rack fixed on the suspension bracket 6, a gear meshing with the rack, and a motor driving the gear, the motor being mounted on the suspension seat 7. Thus, when the coating film released from the coating film roll 4 is laid on the supporting plane 301, the coating film can be automatically cut by the coating film cutting mechanism to cut the coating film into independent pieces. Specifically, after the coating film is adsorbed on the supporting plane 301, the suspension seat drive mechanism drives the suspension seat 7 to move, so that the cutting blade 10 moves together with the suspension seat 7. The cutting blade 10 cuts the coating film adsorbed on the supporting plane 301 to cut the coating film into independent pieces.

[0074] Furthermore, such as Figure 3 , Figure 4 As shown, a roll film wrapping device further includes a first pressing mechanism. The first pressing mechanism includes a first lifting actuator 11 and a pressing rod 12 located above a supporting plane 301. The pressing rod 12 is parallel to the supporting plane 301. A cutting blade 10 is close to the pressing rod 12. The movement direction of the suspension seat 7 is parallel to the pressing rod 12. The first lifting actuator 11 drives the pressing rod 12 to rise and fall, pressing the wrapping film released from the wrapping film roll 4 onto the supporting plane 301. The first lifting actuator 11 is a pneumatic cylinder, an electric cylinder, or an electric push rod. The function of the first pressing mechanism is to press the film onto the supporting plane 301, which facilitates the film cutting mechanism to cut the film. Specifically, after the film is adsorbed onto the supporting plane 301, the first lifting actuator 11 drives the pressing rod 12 to descend, pressing the film onto the supporting plane 301. Then, the suspension seat driving mechanism drives the suspension seat 7 to move, so that the cutting blade 10 moves with the suspension seat 7. The cutting blade 10 cuts the film adsorbed onto the supporting plane 301, which facilitates the film cutting mechanism to cut the film and avoids the film from moving or wrinkling during the cutting process.

[0075] Furthermore, such as Figure 3 , Figure 4As shown, a roll film wrapping device further includes a second film pressing mechanism. The second film pressing mechanism includes a second lifting actuator 13 and a pressure plate 14. The pressure plate 14 is parallel to the supporting plane 301. The pressure plate 14 is parallel to the pressure rod 12. The second lifting actuator 13 drives the pressure plate 14 to rise and fall, pressing the wrapping film released from the wrapping film roll 4 onto the supporting plane 301. The second lifting actuator 13 is a pneumatic cylinder, an electric cylinder, or an electric push rod. A cutting blade 10 is located between the pressure plate 14 and the pressure rod 12. The function of the second pressing mechanism is to cooperate with the first pressing mechanism to press the film onto the supporting plane 301, so as to facilitate the film cutting mechanism to cut the film and further prevent the film from moving or wrinkling during the cutting process. Specifically, after the film is adsorbed onto the supporting plane 301, the first lifting actuator 11 drives the pressure rod 12 to descend, pressing the film onto the supporting plane 301; the second lifting actuator 13 drives the pressure plate 14 to descend, pressing the film released from the film roll 4 onto the supporting plane 301; then the suspension seat driving mechanism drives the suspension seat 7 to move, so that the cutting blade 10 moves with the suspension seat 7. The cutting blade 10 cuts the film in the space between the pressure rod 12 and the pressure plate 14, thus facilitating the film cutting mechanism to cut the film and preventing the film from moving or wrinkling during the cutting process.

[0076] Furthermore, such as Figure 3 , Figure 4 , Figure 5 , Figure 6 As shown, a roll wrapping device further includes a wrapping film laying mechanism. The wrapping film laying mechanism includes a movable frame and a movable frame drive mechanism. The movable frame is slidably mounted on a base platform 3. The sliding direction of the movable frame is perpendicular to the rotation axis of the wrapping film roll 4. In this embodiment, the sliding direction of the movable frame is horizontally distributed. The movable frame is provided with a plurality of clamps for holding the wrapping film. The clamps are located above the supporting plane 301. The movable frame drive mechanism drives the movable frame to move. In this embodiment, the movable frame drive mechanism is a linear module, an electric cylinder, or an electric lead screw drive mechanism. In this embodiment, the movable frame drive mechanism includes a rack fixed on the base platform 3, a gear meshing with the rack, and a motor driving the gear, the motor being mounted on the movable frame. Thus, when it is necessary to release the coating film from the coating film roll 4, one end of the coating film is clamped by the clamp, and then the coating film is released from the coating film roll 4. At the same time, the moving frame drive mechanism drives the moving frame to move the clamp, so that the coating film is spread out on the support plane 301 and adsorbed onto the support plane 301 through the air suction hole 3011.

[0077] In this embodiment, the film-laying mechanism further includes two parallel guide rails 15. The guide rails are horizontally distributed. The guide rails 15 are perpendicular to the rotation axis of the film roll 4. The movable frame includes two movable seats 9 corresponding one-to-one with the guide rails 15 and a connecting beam 8 connecting the two movable seats 9. The movable seats 9 slide along the guide rails 15. The connecting beam 8 is parallel to the rotation axis of the film roll 4. Clamps are disposed on the connecting beam 8. In this embodiment, each clamp is distributed sequentially along the length of the connecting beam 8. This facilitates the installation and arrangement of the clamps and ensures that the movable frame can move smoothly.

[0078] In this specific embodiment, the remaining structure is the same as in specific embodiment one or specific embodiment two, except that...

[0079] like Figure 1 , Figure 3 As shown, the gantry robot 16 can drive two grippers 1601 to move along the XYZ axes. When the two grippers 1601 clamp the roll 17, the rotation axis of the roll 17 is perpendicular to the X-axis. The rotation axis of the coating film roll 4 is parallel to the X-axis. The sliding direction of the moving frame is parallel to the Y-axis. The coating film released from the coating film roll 4 moves along the Y-axis and lays on the supporting plane 301. When the two grippers 1601 clamp the roll 17, the gantry robot 16 drives the roll 17 to move along the X-axis to achieve the coating operation of the roll 17. This facilitates the arrangement of the film roll 4 of the film unwinding device and the roll 17 held by the two grippers 1601, making it easier for the gantry robot 16 to grasp the roll 17 and drive the roll 17 to move along the X-axis to achieve the film wrapping operation. It also avoids collisions with the film roll 4 or other components during the process of the gantry robot 16 grasping the roll 17 and driving the roll 17 to move along the X-axis to achieve the film wrapping operation.

[0080] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
