Description

Technical Field

[0001] The utility model relates to the technical field of film winding equipment, in particular to a reel loading mechanism for film winding. Background Technique

[0002] Film winding is a key link at the end of the film production line. Common winding equipment can achieve automatic winding. After winding is completed, the wound film can also be taken away by hoisting. However, replacing a new empty reel requires manual installation. In the form of hoisting, it is difficult to ensure accurate alignment, so that the empty reel cannot be installed in place, affecting the continuity and efficiency of film winding, and affecting the working efficiency of the entire film production line. Summary of the Invention

[0003] Purpose of the Invention: In order to overcome the deficiencies in the prior art, the utility model provides a reel loading mechanism for film winding, which solves the problem of affecting the film winding efficiency due to the inability to install a new reel in a timely and accurate manner.

[0004] Technical Solution: To achieve the above purpose, a reel loading mechanism for film winding of the utility model includes loading components symmetrically located on both sides of the auxiliary roller. The loading component is provided with a side plate, and a receiving plate is arranged at the loading end of the side plate for receiving and driving the reel to a position where its center is at the same height as the center of the auxiliary roller. A transverse transfer mechanism is arranged between the auxiliary roller and the receiving plate, and a limiting plate is fixedly arranged on the end face of the auxiliary roller. A positioning member is fixedly arranged above the limiting plate, and a rotating shaft is rotatably matched with the center of the limiting plate. A lifting plate is fixedly connected to the rotating shaft. When the lifting plate swings to the lower limit position, it corresponds to the material clamping groove of the transverse transfer mechanism. When the lifting plate swings to the upper limit position, a vertical limiting groove is formed between the lifting plate and the positioning member, and the limiting groove is located directly above the auxiliary roller.

[0005] Further, the receiving plate is swingably arranged inside the side plate, and a limiting surface adapted to the outer circumferential surface of the reel is arranged at the swinging end of the receiving plate. When the receiving plate swings to the vertical position, the center positions of the reel in contact with the limiting surface and the auxiliary roller are at the same height.

[0006] Further, a guide rolling surface is arranged on one side of the limiting surface away from the auxiliary roller, and a limiting roller is arranged on one side of the limiting surface close to the auxiliary roller.

[0007] Further, the limiting plate is a disc structure with the same diameter as the auxiliary roller, and the limiting plate and the auxiliary roller are coaxially arranged.

[0008] Further, the transverse conveying mechanism includes a main slider, which is slidably engaged with a guide bar on the inner side of the side plate. The guide bar is arranged horizontally. An arc mating surface and a limiting post are provided at the upper end of the main slider. The arc mating surface faces the side of the material receiving plate, and the limiting post is telescopically arranged on the facing side of the arc mating surface. The material clamping groove with an upward opening is formed between the arc mating surface and the limiting post.

[0009] Further, a positioning pin and a position sensor are fixedly arranged on the inner side of the side plate. The positioning pin and the position sensor are arranged flush with each other vertically. The positioning pin is inserted and engaged with a positioning hole on the side surface of the material receiving plate. The position sensor is electrically connected to the telescopic driving module of the limiting post and the sliding driving module of the main slider; a winding drum induction module is fixedly arranged on the lifting plate. The winding drum induction module is electrically connected to the lifting and lowering driving module of the lifting plate.

[0010] Beneficial effects: The winding drum feeding mechanism for film winding of the present invention realizes the state that the winding drum continuously experiences the handover among the three components of the material receiving plate, the transverse conveying mechanism, and the lifting plate and is finally transported to a state where it maintains a preset relative position relationship with the auxiliary roller by the movement cooperation and positioning constraint among the material receiving plate, the transverse conveying mechanism, and the lifting plate. It ensures the accurate alignment during the installation of the winding drum, and the process is controlled by sensor induction, which can automatically realize the feeding of the winding drum, maintain the continuous working state of the film winding station, and improve the overall winding efficiency. Description of the Drawings

[0011] Figure 1 It is a schematic diagram of the overall structure of an embodiment of the present invention. Detailed Embodiment

[0012] The present invention will be further described below with reference to the drawings.

[0013] As shown in the attached Figure 1 The winding drum feeding mechanism for film winding includes a feeding assembly symmetrically located on both sides of the auxiliary roller. The feeding assembly is provided with a side plate 1. A material receiving plate 2 is arranged at the feeding end of the side plate 1 for receiving and driving the winding drum 4 to a position where its center is at the same height as the center of the auxiliary roller; a transverse conveying mechanism 5 is arranged between the auxiliary roller and the material receiving plate 2. A limiting plate 4 is fixedly arranged at the end face of the auxiliary roller; a positioning member 6 is fixedly arranged above the limiting plate 4. A rotating shaft is rotatably fitted at the center of the limiting plate 4. A lifting plate 7 is fixedly connected to the rotating shaft. When the lifting plate 7 swings to the lower limit position, it corresponds to the material clamping groove of the transverse conveying mechanism 5. When the lifting plate 7 swings to the upper limit position, a vertical limiting groove is formed between the lifting plate 7 and the positioning member 6. The limiting groove is located directly above the auxiliary roller. Among them, the limiting plate 4 is a disc structure with the same diameter as the auxiliary roller, and the limiting plate 4 and the auxiliary roller are coaxially arranged.

[0014] The roll is then moved vertically along the limit groove, that is, as the thickness of the film on the roll gradually increases, the roll can adaptively move upward along the limit groove, so that the auxiliary roller is always in contact with the outer layer of the film roll, thereby ensuring the flatness of the film during the winding process.

[0015] The receiving plate 2 is swingably arranged inside the side plate 1, and a limiting surface 22 is arranged at the swinging end of the receiving plate 2 to match the outer circumferential surface of the reel 4; when the receiving plate 2 is swung to a vertical position, the reel 4 that is in close contact with the limiting surface 22 has the same center position as the auxiliary roller. A guide roller surface 21 is arranged on the side of the limiting surface 22 away from the auxiliary roller, and a limiting roller wheel 23 is arranged on the side of the limiting surface 22 close to the auxiliary roller.

[0016] Specifically, the bottom end of the material receiving plate can be hinged to the inner wall of the side plate, and the material receiving plate can be driven by the cylinder to rotate and tilt in the direction of the roll conveyor belt, so that the dropped roll can roll downward along the guide roller surface until the roll just fits with the limiting surface, and when fitting, the limiting roller just fits with the outer wall surface of the roll, which can constrain the abutting and matching relationship between the roll and the limiting surface, ensuring that the roll will not separate from the limiting surface during the process of the material receiving plate actively moving to the vertical state, thereby ensuring that when reaching the vertical state position, the roll on it can just fit with the material picking part of the transverse conveying mechanism, thereby ensuring that the roll will not move when transferred between the handling modules.

[0017] The transverse conveying mechanism 5 includes a main slider, which is slidably matched with the guide bar 11 on the inner side of the side plate 1. The guide bar 11 is arranged horizontally. An arc matching surface 51 and a limit column 52 are arranged on the upper end of the main slider. The arc matching surface 51 faces the side of the receiving plate 2, and the limit column 52 is telescopically arranged on the facing side of the arc matching surface 51. The arc matching surface 51 and the limit column 52 form the material clamping groove that opens upward.

[0018] Preferably, the arc mating surface and the limiting surface are both set to be 1 / 4 arc surfaces. When the main slider slides to the position where the reel is connected with the material receiving plate, the arc mating surface and the limiting surface just form a semicircular arc surface. When both are in contact with the reel at the same time, the limiting column is controlled to extend, thereby forming a clamping groove, so that the reel is limited and fits on the arc mating surface. Under the sliding action of the main slider, the reel is driven away from the limiting surface of the material receiving plate. The notch of the constructed clamping groove is set in a direction so that the reel can move upward, thereby providing an escape space for the reel to pass over the limiting roller and be lifted out of the clamping groove by the lifting plate.

[0019] A positioning pin 12 and an in-place sensor 13 are fixedly provided on the inner side of the side panel 1. The positioning pin 12 and the in-place sensor 13 are arranged flush with each other up and down. The positioning pin 12 is inserted into and matched with the positioning hole on the side of the receiving plate 2. The in-place sensor 13 is electrically connected to the telescopic driving module of the limiting column 52 and the sliding driving module of the main slider; a roll sensing module 7 is fixedly provided on the lifting plate 7, and the roll sensing module 7 is electrically connected to the lifting and lowering driving module of the lifting plate 7.

[0020] The positioning pin is used to constrain the receiving plate in a vertical state to ensure the position accuracy when the roll is handed over. The vertical state of the receiving plate is sensed by the in-position sensor, thereby controlling the extension of the limit column. The roll sensing module is used to sense the relative position of the roll relative to the lifting plate. After ensuring that the relative position is determined, the lifting plate is controlled to rotate upward, thereby lifting the roll to the top of the auxiliary roller. After it is in place, the roll is connected to the rotating mechanism by the fixed connection at the end to achieve the purpose of film winding.

[0021] Based on the above structure, during the preparation stage of the roll installation and loading, the receiving plate is swung to an inclined state so that its swinging end is close to the roll conveyor belt, and at the same time the transverse conveying mechanism is moved to the extreme position close to the receiving plate, and the lifting plate is rotated 90 degrees from a vertical state toward the transverse conveying mechanism to a horizontal state.

[0022] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
