Description

Technical Field

[0001] The utility model relates to the technical field of mounting machine equipment, in particular to an automatic parking device for a mounting machine. Background Art

[0002] A transparent coating is applied to the surface of rolled flat materials (such as paper, photos, posters, paintings, etc.) through a mounting machine, which can increase the gloss of the material, protect it from damage, and extend its service life. Generally, during lamination, the unwinding film roller is passively pulled forward, and the material and film pass through the upper and lower rubber rollers for lamination. The lamination effect can also be better through the use of a film pressing roller. When the film roller is unwound, it is necessary to stop the machine immediately and replace the film roller, otherwise the film supply will be interrupted, the lamination operation cannot be completed, and the lamination quality will be affected.

[0003] In the prior art, many mounting machines rely on infrared to sense the absence of film and send a signal to a controller to stop the mounting machine. However, if the film is transparent or pure black, the infrared cannot receive the signal reflected by the film, so the automatic parking of the mounting machine will be affected.

DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, in the following description, specific details such as specific system structures and technologies are proposed for the purpose of explanation rather than limitation, so as to thoroughly understand the embodiments of the utility model. However, it should be clear to those skilled in the art that the utility model can also be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from hindering the description of the utility model.

[0037] The utility model provides an automatic parking device for mounting machine. Figure 1 -Attached Figure 5 It can be known that the automatic parking device of the mounting machine includes: a first support plate 11 and a second support plate 12 , an air expansion shaft 13 , a connecting shaft 14 , a braking mechanism 20 , a rotating induction plate 31 , an induction seat 32 , and a photoelectric sensor 33 .

[0038] The first support plate 11 and the second support plate 12 are arranged at intervals, one end of the air expansion shaft 13 is connected to and penetrates the rotating shaft of the first support plate 11, the other end of the air expansion shaft 13 is connected to and penetrates the rotating shaft of the second support plate 12 through a connecting shaft 14, and the other end of the air expansion shaft 13 is connected to an air source, so that the air expansion shaft 13 can tighten the film roller.

[0039] The brake mechanism 20 is arranged on the connecting shaft 14 and connected to the second support plate 12, and is used to provide friction damping for the connecting shaft 14 and the air expansion shaft 13. The rotating induction disc 31 is arranged on the connecting shaft 14 that passes through the second support plate 12, and rotates synchronously with the connecting shaft 14 under the action of the brake mechanism 20, and the rotating induction disc 31 is evenly provided with a plurality of grooves 311 in the circumferential direction; the induction seat 32 is arranged on one side of the rotating induction disc 31, and the photoelectric sensor 33 arranged on the induction disc is electrically connected to the controller, and the rotation of the rotating induction disc 31 is sensed by the photoelectric sensor 33. When the signal pattern detected by the photoelectric sensor 33 is abnormal, the controller controls the mounting machine to stop.

[0040] During normal operation, the film roller is unwinding. At this time, the friction damping provided by the brake mechanism 20 to the connecting shaft 14 can keep the film in a taut state while moving forward, which will have a good effect on the quality of the film coating. After the film roller is unwinding, different parts of the air-inflating shaft 13 will be subjected to different degrees of inertial force. Due to the effect of friction damping, the air-inflating shaft 13 and the connecting shaft 14 will stop rotating immediately. If the connecting shaft 14 does not have friction damping, it will easily cause the air-inflating shaft 13 and the connecting shaft 14 to rotate due to the large inertial force, affecting the accuracy of the detection of the photoelectric sensor 33, and the film roller cannot be detected in time. There is no way to control the mounting machine to stop in time.

[0041] As the film roller is unwound, it is passively pulled to rotate. Since the rotating induction disc 31 is provided with a plurality of grooves 311, under normal working conditions, the signal received by the photoelectric sensor 33 is regular on-off-on-off..., and transmits the signal to the controller. When the photoelectric sensor 33 detects only on or only off signals, the signal pattern changes, indicating that the rotating induction disc 31 and the connecting shaft 14 have stopped rotating, and the film roller unwinding is completed. At this time, the controller can control the mounting machine as a whole to stop in time. This detection method is accurate, will not be affected by the color of the film on the detection situation, and is more practical.

[0042] As an embodiment, according to the attached Figure 2 It can be seen that a stop seat 34 is provided on the second support plate 12 , and the upper end of the stop seat 34 is inclined toward the rotating induction disk 31 . The stop seat 34 is away from the side of the rotating induction disk 31 and is hinged to the bottom of the induction seat 32 .

[0043] When it is necessary to detect the rotation of the rotating sensing disk 31, the sensing seat 32 can be swung to make it connect with the side corresponding to the stop seat 34, and the stop seat 34 plays a supporting role for the sensing seat 32; when the sensing seat 32 is swung to keep it away from the rotating sensing disk 31, it is convenient to disassemble and assemble the various parts on the connecting shaft 14, which can make the device more flexible to use.

[0044] As an embodiment, according to the attached Figure 3 -Attached Figure 5It can be seen that the brake mechanism 20 includes a first friction plate 21, a second friction plate 22, a damping positioning plate 23, an elastic connecting member 24, a limiting sleeve 25, and an adjusting member 26, which are sequentially and coaxially arranged along the axial direction of the connecting shaft 14; the first friction plate 21 is fixedly arranged on the outer side of the second support plate 12, and the second friction plate 22 is connected to the first friction plate 21 by glue; the keyway 231 arranged in the middle of the damping positioning plate 23 is horizontally slidably connected to the sliding key 141 arranged on the connecting shaft 14, and the damping positioning plate 23 generates friction damping with the second friction plate 22 through the elastic connecting member 24, the elastic connecting member 24 is connected to the rotating induction plate 31, and under the action of the elastic connecting member 24, the rotating induction plate 31 can rotate synchronously with the connecting shaft 14; the limiting sleeve 25 can be horizontally slidably sleeved on the connecting shaft 14 under the action of the adjusting member 26, and is detachably connected to the connecting shaft 14 through a quick release assembly.

[0045] The elastic connecting member 24 can give an elastic force to the damping positioning plate 23, so that friction damping is generated between the damping positioning plate 23 and the second friction plate 22. The limiting sleeve 25 has a limiting effect on the damping positioning plate 23 and the elastic connecting member 24, and the limiting sleeve 25 is driven by the adjusting member 26 to move horizontally on the connecting shaft 14 to adjust the elastic force of the elastic connecting member 24 on the damping positioning plate 23. In the process of adjusting the force, the damping positioning plate 23 moves horizontally on the connecting shaft 14 through the connection and guiding effect of the key slot 231 and the sliding key 141.

[0046] The air shaft 13 supporting the film roller is generally braked by two friction plates to improve the friction damping of the air shaft 13. The friction plate is a consumable part. If the friction plate is not easy to replace, the downtime will increase and the work efficiency will be affected. Therefore, after the limit sleeve 25 is disassembled by the quick-release assembly, it is convenient to subsequently remove the elastic connection member 24 and the rotation induction plate 31. After the damping positioning plate 23 is disassembled, the friction plate is replaced.

[0047] In this embodiment, according to the specification Figure 3 It can be seen that the elastic connecting member 24 includes: a compression spring 241 sleeved on the connecting shaft 14; two damping sleeves 242 are relatively arranged at both ends of the compression spring 241, and the rotating induction plate 31 is arranged between the compression spring 241 and the damping sleeve 242 on the side close to the damping positioning plate 23.

[0048] Under the action of the compression spring 241, the damping positioning plate 23 has good contact with the second friction plate 22, providing friction damping to the connecting shaft 14. In addition, under the elastic force of the compression spring 241 and the torque transmission effect of the two damping sleeves 242, the rotating induction plate 31 and the connecting shaft 14 rotate synchronously.

[0049] In this embodiment, according to the specification Figure 3 and attached Figure 5It can be seen that the quick-release assembly includes: a flat groove 143 is arranged on the connecting shaft 14 and along its axial direction, and corresponds to the position of the limiting sleeve 25; the limiting leaf spring 27 includes a horizontal thin sheet 271 and an L-shaped spring sheet 272, the horizontal thin sheet 271 is connected to one end of the flat groove 143, when the spring sheet 272 is in a free state, it extends out of the long slot hole 251 set on the limiting sleeve 25, when the spring sheet 272 is pressed to make it extend into the limiting sleeve 25, the limiting sleeve 25 can be disassembled.

[0050] The horizontal sheet 271 is fixed on the flat groove 143 by screws and nuts, and the spring 272 includes a connecting portion connected to the horizontal sheet 271 and a free portion arranged perpendicular to the horizontal sheet 271. In the free state, the connecting portion is not in the same plane as the horizontal sheet 271, and the corner of the spring 272 will extend out of the long slot hole 251 on the limiting sleeve 25, which plays a limiting role for the limiting sleeve 25; when the limiting sleeve 25 needs to be disassembled, the connecting portion of the spring 272 is pressed down, so that the free portion extends into the limiting sleeve 25 and is inserted into the through slot 144 arranged on the connecting shaft 14, and the limiting sleeve 25 can be disassembled at this time.

[0051] In this embodiment, according to the specification Figure 3 It can be seen that the adjusting member 26 is an adjusting handle, the middle of which is threadedly connected to the threaded section 142 provided at the end of the connecting shaft 14. One end of the adjusting handle is in contact with the limiting sleeve 25, and the limiting sleeve 25 is driven to slide horizontally on the connecting shaft 14 by rotating the horizontal displacement between the adjusting handle and the connecting shaft 14. When the compression spring 241 is compressed, its elastic force will push the connected damping positioning plate 23 to move inward, thereby increasing the friction damping.

[0052] In this embodiment, the damping sleeve 242 is made of nylon, and its main function is to absorb mechanical vibration and impact force.

[0053] In this embodiment, the first friction plate 21 is detachably disposed on the second support plate 12 by means of a plurality of screws, so that the installation and replacement of the first friction plate 21 can be facilitated.
