Description

Technical Field

[0001] The present invention relates to a product packaging film pasting system, in particular to a fence automatic film pasting system that realizes full-process automatic film pasting. Background Art

[0002] Fences are common profile products in life, usually composed of at least two horizontal bars in the horizontal direction and several vertical bars in the vertical direction. When they are manufactured and leave the factory, a film is pasted on them to protect the surface of the rails during subsequent storage and transportation.

[0003] In the film pasting process of traditional fence products, the staff manually place the fence in position at the film pasting rack, and manually paste the film according to different film pasting methods. After pasting, the staff then take down the fence and place it in the material box. Each time of material taking, film pasting, and material discharging requires at least 2 people to cooperate. According to the different specifications of the fence, the number of staff participating in the above process will increase.

[0004] With the gradual acceleration of social development and urbanization, the demand and output of profiles are increasing year by year. It is necessary to improve the production efficiency of fence products. For the staff, the labor intensity of manual loading, unloading, and film pasting is getting greater and greater. Moreover, the processes of manual loading, unloading, and film pasting are not accurate enough, and the quality of manual film pasting is also easily affected by various factors, resulting in an unbeautiful situation. The demand for production automation in the profile production field is becoming more and more urgent. Summary of the Invention

[0016] The present invention is a full-automatic production line including feeding, film pasting, and blanking. The beneficial effects are as follows.

[0017] (1) The structures of the loading machine and the unloading machine are basically the same. It can control the clamping action of the clamping hand, and the movement of the horizontal and vertical moving devices through preset parameters.

[0018] (2) The three-sided packaging film laminating machine uses 3 imprinting rollers for the outer side, top surface, and bottom surface of the fence crossbar for automatic film laminating and conveying. It can laminate about 8 in one minute. Compared with the existing manual film laminating, the efficiency is increased by about 400%, and the labor intensity of employees is greatly reduced.

That is, manually lift the fence to be film laminated in the material box and place it at the film laminating position, and 2 people cooperate to laminate the film, and then manually lift the film-laminated fence and place it in the material box of the subsequent process. When different film laminating methods or fence specifications are required, more people may be involved in this process. The number of people increases but the efficiency is not improved. And because the film laminating process has certain requirements for fineness and cannot blindly pursue speed, the time is uncontrollable, and it is difficult to effectively balance time and quality. By applying the automatic film laminating system in the present invention, after presetting the parameters of clamping and moving, the processes of loading, film laminating, and unloading are all mechanized and automated. Only 1 person is on duty to handle possible emergencies, saving manpower, reducing the labor intensity of personnel, and the time and quality of the film laminating process are stable, effectively improving the efficiency.

Detailed implementation mode

[0040] In the present invention, the direction in which the fence moves forward is defined as the rear, the direction in which the material comes is defined as the front, and the directions perpendicular to the direction in which the fence moves forward are defined as both sides; it is defined that when the fence is in a Figure 6 flat state, the up and down directions are the outer sides, the connection between the horizontal bar and the vertical bar is the inner side, the side in contact with the driving roller is the bottom surface, and the side opposite to the bottom surface is the top surface. The above definitions are only for the convenience of explanation and description, but the present invention is not limited to the above orientations.

[0041] The fence automatic film pasting system of the present invention is a full-automatic production line including feeding, film pasting, and discharging. As shown in the embodiment, the system includes a feeding machine 1, a feeding conveyor frame 4, a film pasting machine 2, a shearing conveyor frame 7, a discharging conveyor frame 5, and a discharging machine 3 arranged in the forward movement direction. The discharging conveyor frame 5 can be selected to be configured in the whole system according to actual situations.

[0042] The loading machine 1 at least includes a loading support, a loading transverse movement mechanism, a loading longitudinal movement mechanism, and a loading gripper. The loading transverse movement mechanism is connected to the loading support. The loading longitudinal movement mechanism is installed on the loading transverse movement mechanism, and the loading gripper is installed at the bottom of the loading longitudinal movement mechanism.

[0043] As Figures 1 to 3 shown in the embodiment, the loading support includes two loading longitudinal rods 111 and a loading transverse movement support 112 connected to the upper sections of the two loading longitudinal rods 111. The loading transverse movement support 112 extends horizontally to form a range that can drive the fence materials to move along the movement direction. A loading transverse movement guide rail 113 is provided on the loading transverse movement support 112.

[0044] The loading transverse movement mechanism includes a first mounting plate 122, and six loading transverse movement sliders 121 that are connected to the bottom of the first mounting plate 122 and cooperate with the loading transverse movement guide rail 113. A first servo motor 123 is installed on the upper surface of the first mounting plate 122, which controls the six loading transverse movement sliders 121 to move horizontally on the loading transverse movement guide rail 113. A loading transverse movement limit photoelectric eye 124 is also provided at a suitable position on the first mounting plate 122 for sensing the moving position of the entire loading transverse movement mechanism.

[0045] The loading longitudinal movement mechanism includes a second servo motor 133 and a loading transmission rod 131 whose moving position is controlled by the second servo motor 133. The loading transmission rod 131 passes through a first through hole preset on the first mounting plate 122. A loading linear guide rail slider 134 is provided beside the first through hole, which includes a first limit groove. One side of the loading transmission rod 131 is placed in the first limit groove and can move up and down. The second servo motor 133 is installed on the first mounting plate 122. The loading transmission rod 131 is a rack, and the second servo motor 133 drives the loading transmission rod 131 to move up and down by means of gear and rack cooperation. The loading linear guide rail slider 134 is used to stabilize the up-and-down vertical movement of the loading transmission rod 131 when the loading transmission rod 131 and the gear are stressed against each other and prevent it from tilting. The bottom of the loading transmission rod 131 is connected to a second mounting plate 132, and the second mounting plate 132 is connected to the loading gripper. In addition, a loading longitudinal movement limit photoelectric eye 135 can also be provided beside the first through hole for sensing the moving position of the entire loading longitudinal movement mechanism.

[0046] The loading gripper includes a frame-shaped loading gripper bracket 141, which is connected to the bottom or periphery of the second mounting plate 132. Pairs of loading gripper cylinders 143 are provided at the front and rear sections of the bottom of the loading gripper bracket 141. The ends of the expansion rods of the pairs of loading gripper cylinders 143 extending outwardly are connected to loading gripper plate members 144. By electrically controlling the expansion and contraction of the expansion rods of the loading gripper cylinders 143, the pairs of loading gripper plate members 144 move outwardly or inwardly simultaneously to achieve the gripping action. A loading limit rod is connected to the loading gripper bracket 141, and first material clamping limit photoelectric eyes 145 are provided at one or both ends of the rod to sense the positions of the loading gripper bracket 141, the loading gripper plate members 144 and the materials on the fence of the material cart. To better implement the above functions, the end of the loading limit rod can be bent downward, the first material clamping limit photoelectric eye 145 is installed at the bottom of the bend, and it is optimal that the bent part of the loading limit rod and the first material clamping limit photoelectric eye 145 are arranged on the same outer side as the loading gripper plate member 144, and it is optimal that the height of the first material clamping limit photoelectric eye 145 is lower than the bottom edge of the loading gripper plate member 144, so that Figure 1 as shown, when gripping the fence, the positions of the gripped materials and the materials below can be accurately sensed.

[0047] The loading conveyor rack 4, the film laminating machine 2, the shearing conveyor rack 7, and the unloading conveyor rack 5 all include a bottom frame for support. A plurality of driving rollers are arranged in parallel on each bottom frame, and both ends of the driving rollers are arranged on the long sides on both sides of the bottom frame through bearing seats. The driving rollers rotate forward or backward in the traveling direction to realize the traveling of the fence.

[0048] The structure of the loading conveyor rack 4 in this embodiment is specifically combined with Figures 1 to 3 as shown. A support plate 4112 is arranged as needed between the long sides 4111 of the two loading bottom frames. Two symmetrically arranged side shift cylinders 4121 are arranged on the support plate 4112. A vertically upwardly arranged vertical positioning roller 4122 is connected to the end of each side shift cylinder 4121 near the long side 4111 of the loading bottom frame. The positions of the two vertical positioning rollers 4122 can be adjusted by their respective side shift cylinders 4121 to adapt to the width of the fence 6 to be film laminated. A cycloidal pinwheel speed reducer 413 is arranged at a suitable position on the long side 4111 of the loading bottom frame, and it is connected to the bearing seat on one side of the bottom of the driving roller through a transmission rod and bevel gears.

[0049] In the film laminating machine 2 in this system, different types of film laminating machines can be used according to the actual situation. The following takes an automatic three-sided film laminating machine as an example for illustration.

[0050] Combined with as Figures 5 to 11As shown, the drive roller between the long sides 211 of the film pasting chassis on both sides of the film pasting machine 2 may include a groove matching the width D2 of the cross bar 61 of the fence. To save materials, it can also be provided with soft felt at both ends and without soft felt in the middle, only having a central rotating shaft, and can be adjusted according to actual needs.

[0051] First limit rollers 22 are symmetrically arranged on the long sides 211 of the film pasting chassis on both sides of the film pasting machine 2, and are arranged in a way that the rotating shafts are vertical and horizontal. It also includes at least two second limit rollers 23 parallel to the upper side of the drive roller, and they are arranged in a way that the rotating shafts are horizontal and vertical. The second limit rollers 23 can be moved up and down to adjust the distance from the drive roller. Specifically, the second limit rollers 23 are installed on the chassis through the mounting frame 231. The bottom end of the mounting frame 231 is fixed on the film pasting machine chassis 21. A lift rod 233 that can be lifted and lowered is arranged in the mounting frame 231. Slideways are included on the inner side of the side of the mounting frame 231. Both ends of the lift rod 233 slide in the slideways in a matching manner to achieve lifting and lowering. An adjusting screw 232 passing through the top of the mounting frame 231 is connected to the lift rod 233. Rotating the adjusting screw 232 can adjust the position of the lift rod 233. A lifting cylinder 234 is also arranged on the lift rod 233. The bottom of the lifting cylinder 234 is connected to the middle section of the second limit roller 23. Specifically, a roller positioning housing is provided in the middle section of the second limit roller 23, which can fix the relative position with the lifting cylinder 234 and has no influence on the housing when the second limit roller 23 rotates. The position of the second limit roller 23 can be finely adjusted through the lifting cylinder 234. For the connection structure between the above-mentioned roller positioning housing and the second limit roller 23 below, any connection and rotation structure that can achieve the above structure and function can be used, and will not be specifically described here.

[0052] Combined Figures 7 to 10 As shown, first imprinting rollers 241, second imprinting rollers 242, and third imprinting rollers 243 are also arranged on both sides of the film pasting chassis 21. The first imprinting rollers 241 are arranged in a way that the rotating shafts are vertical and horizontal, and include a first working groove 2411 matching the thickness D1 of the cross bar 61 of the fence 6. The height H1 of the first working groove 2411 matches the cross-sectional thickness D1 of the cross bar 61, and H1 can be slightly larger than D1; the depth H2 of the first working groove 2411 can be selected according to actual situations. In the illustrated embodiment, the depth H2 is less than the width D2 of the cross section of the cross bar 61. The first working groove 2411 is used to pre-wrap the whole piece of film along the transmission direction on the outer side, top surface, and bottom surface of the cross bar 61.

[0053] The second impression cylinder 242 and the third impression cylinder 243 are arranged in such a way that their rotating shafts can rotate horizontally and vertically. It is better that the second impression cylinder 242 and the third impression cylinder 243 are respectively arranged above and below the fence, staggered front and back. The front-back order of the two can be arranged according to the actual situation. The second impression cylinder 242 includes a second working groove 2421 that matches the width D2 of the cross bar 61 of the fence 6. The width L1 of the second working groove 2421 matches the width D2 of the cross section of the cross bar 61, and L1 can be slightly larger than D1; the diameter or width of the longitudinal bar 62 of the fence 6 is smaller than the thickness D1 of the cross bar 61. Therefore, the distance between the top surface of the cross bar 61 and the edge of the top surface of the longitudinal bar 62 is D3, and the depth L2 of the second working groove 2421 is less than D3. The second impression cylinder 242 is used to press the film pre-coated on the top surface of the cross bar tightly, and at the same time guide and bend the film into the inner side of the cross bar 61. The third impression cylinder 243 includes a third working groove that matches the width D2 of the cross bar 61 of the fence 6. Generally, the third impression cylinder 243 uses components with the same specifications as the second impression cylinder 242, so it will not be specifically described here. The third impression cylinder 243 is used to press the film pre-coated on the bottom surface of the cross bar 61 tightly, and at the same time guide and bend the film into the inner side of the cross bar 61. Through the combined action of the first, second, and third impression cylinders, the film is firmly and smoothly attached to the cross bar 61.

[0054] The film laminating machine 2 is also provided with a tape supply device, which at least includes a film laminating tape roll 251 and a guiding roller 252 as shown in the figure. The guiding roller 252 is arranged before the first impression cylinder 241, and it is used to pre-press the film on the film laminating tape roll 251 on the side of the cross bar 41. At this time, the film between the film laminating tape roll 251 and the guiding roller 252 is in a straightened and complete state. According to the actual situation, the existing first limiting roller 22 can also be used as the guiding roller 252.

[0055] Adjusting mechanisms that can be finely adjusted are provided at the bottoms of the first limiting roller 22, the first impression cylinder 241, the second impression cylinder 242, the third impression cylinder 243, and the film laminating tape roll 25 to adapt to fences of different specifications. The above-mentioned driving rollers, positioning rollers, the first limiting roller 22, the second limiting roller 23, and the guiding roller 252 can be made of soft felt rollers to protect the fence 6 without abrasion. The first impression cylinder 241, the second impression cylinder 242, and the third impression cylinder 243 are made of PP material.

[0056] A servo motor and a speed reducer are set at an appropriate position of the film laminating chassis 21 to control the actuation of the driving sprocket and the driving roller.

[0057] Such as Figure 7 , Figure 11 and Figure 12As shown in the figure, a film shearing device for shearing the film is provided on the shearing conveyor rack 7, which includes a heating wire bracket 71 provided at the starting section of the shearing conveyor rack 7, and the bottom of the heating wire bracket 71 is connected to the shearing bottom rack 73. An L-shaped lifting arm 72 is provided on the heating wire bracket 71. One end of the L-shaped lifting arm 72 realizes lifting on the heating wire bracket 71, and the other end is above the shearing bottom rack 73. A straightened heating wire is provided at the position corresponding to the cross bar 61.

[0058] In addition to the embodiment shown in the figure, if it is required in actual engineering, the blanking conveyor rack 5 may not be provided.

[0059] The structure and movement mode of the blanking machine 3 are basically the same as those of the loading machine 1, but the moving directions are opposite.

[0060] The blanking machine 3 at least includes a blanking bracket, a blanking transverse movement mechanism, a blanking longitudinal movement mechanism and a blanking gripper. The blanking transverse movement mechanism is connected to the blanking bracket, the blanking longitudinal movement mechanism is connected to the blanking transverse movement mechanism, and the blanking gripper is installed at the bottom of the blanking longitudinal movement mechanism.

[0061] As Figures 13 to 15 In the embodiment shown in the figure, the blanking bracket includes two blanking longitudinal rods 311 and a blanking transverse movement bracket 312 connected to the upper sections of the two blanking longitudinal rods 311. The blanking transverse movement bracket 312 extends horizontally to form a range that can drive the movement of the fence material, and a blanking transverse movement guide rail 313 is provided on the blanking transverse movement bracket 312.

[0062] The blanking transverse movement mechanism includes a third mounting plate 322, and six blanking transverse movement sliders 321 that are connected to the bottom of the third mounting plate 322 and cooperate with the blanking transverse movement guide rail 313 are provided. A third servo motor 323 is installed on the third mounting plate 322, which controls the movement of the six blanking transverse movement sliders 321 on the blanking transverse movement bracket 312. A blanking transverse movement limit photoelectric eye 324 is provided at a suitable position on the third mounting plate 322 for sensing the movement position of the entire blanking transverse movement mechanism.

[0063] The blanking longitudinal movement mechanism includes a fourth servo motor 333 and a blanking transmission rod 331 whose moving position is controlled by it. The blanking transmission rod 331 passes through a second through hole preset on the third mounting plate 322. A blanking linear guide slider 334 is arranged beside the second through hole, which includes a second limiting groove. One side of the blanking transmission rod 331 is placed in the second limiting groove and can move up and down. The function of the blanking linear guide slider 334 is the same as that of the loading linear guide slider 134. The fourth servo motor 333 is installed on the third mounting plate 322. The blanking transmission rod 331 is a rack, and the fourth servo motor 333 drives the blanking transmission rod 331 to move up and down by means of a gear meshing with the rack. The bottom of the blanking transmission rod 331 is connected to a fourth mounting plate 332, and the fourth mounting plate 332 is connected to the loading gripper. A blanking longitudinal movement limit photoelectric eye 335 can also be arranged beside the second through hole, which is used to sense the moving position of the whole loading longitudinal movement mechanism.

[0064] The blanking gripper includes a frame-shaped blanking gripper bracket 341, which is connected to the bottom or periphery of the fourth mounting plate 332. At the front and rear sections of the bottom of the blanking gripper bracket 341, paired blanking gripper cylinders 343 are arranged. The ends of the expansion rods extending outward from the paired blanking gripper cylinders 343 are connected to blanking gripper plate members 344. By electrically controlling the expansion and contraction of the expansion rods of the blanking gripper cylinders 343, the paired blanking gripper plate members 344 move outward or inward simultaneously to achieve the gripping action. A blanking limit rod is connected to the blanking gripper bracket 341, and second material clamping limit photoelectric eyes 345 are arranged at one or both ends of the blanking limit rod to sense the positions of the blanking gripper bracket 341, the blanking gripper plate members 344 and the materials on the fence of the material cart. In order to better realize the above functions, the end of the blanking limit rod can be bent downward, the second material clamping limit photoelectric eye 345 is installed at the bottom of the bend, and it is best that the bent part of the blanking limit rod and the second material clamping limit photoelectric eye 345 are arranged on the same side as the blanking gripper plate members 344, and it is best that the height of the second material clamping limit photoelectric eye 345 is lower than the bottom edge of the blanking gripper plate members 344, so that Figure 13 as shown, when putting down the fence, the positions of the gripped materials and the materials below can be accurately sensed.

[0065] The different structure of the blanking machine 3 from the loading machine 1 is that the blanking gripper cylinder 343 is a cylinder with a fine-tuning sliding component 8, which can be used to replace the function of the misalignment of the fence materials during the manual stacking process. Specifically, the fine-tuning sliding component 8 is arranged between the blanking gripper bracket 341 and the blanking gripper cylinder 343. The fine-tuning sliding component 8 includes a fine-tuning slide rail 81 and a fine-tuning slider 82 that cooperate with each other to slide. As Figure 18 shown, the fine-tuning slider 82 is connected to the bottom of the blanking gripper bracket 341 above, and the fine-tuning slide rail 81 is connected to the blanking gripper cylinder 343 below, or the opposite sliding connection method.

[0066] The overall system and specific structural details in the illustrated embodiments are described above. The following describes the automated process when applying this system.

[0067] (1) Loading: The finished product bin of the stacker crane is transported to the lower part of the front section of the loading machine 1 as shown in Figure 1 and Figure 2 At this time, the first servo motor 123 drives the first mounting plate 122 to also run to the front section of the loading transverse movement bracket 112. The second servo motor 133 drives the loading transmission rod 131 to move downward. At the same time, the loading clamping cylinder 143 drives the loading clamping plate member 144 to push open to both sides and be greater than the overall width of the fence 6. When the loading longitudinal movement limit photoelectric eye 135 senses that the loading clamping plate member 144 can just clamp the highest 1 fence 6, the loading transmission rod 131 stops moving. The loading clamping plate member 144 pulls back inward to clamp the outside of the fence crossbar 61. The loading transmission rod 131 moves upward to clamp the fence 6 from the bin of the stacker crane. At the same time, the first servo motor 123 drives the entire loading transverse movement mechanism and loading longitudinal movement mechanism to move backward to the rear section of the loading transverse movement bracket 112, as shown in Figure 4 . Then, the fence is lowered to the front section of the loading conveyor 4 in a manner opposite to the above process, that is, the automatic loading process of 1 fence 6 is completed. After the loading clamping plate member 144 opens and puts down the fence 6, the loading transverse movement mechanism and loading longitudinal movement mechanism return to the front section of the loading machine 1 to clamp the next fence 6.

[0068] (2) Film sticking: The driving roller of the loading conveyor 4 is driven by a motor to automatically convey the fence 6 to the front section of the film sticking machine 2, as shown in Figures 5 to 7As shown, the first limiting roller 22, a group of second limiting rollers 23 and the conveying roller 5 work together to make the fence 6 stably conveyed backward without deviation. The horizontal bar 61 of the fence 6 reaches the guide roller 252, and the film is first pre-attached to the outer side of the horizontal bar 61; then it passes through the first working groove 2411 of the first impression roller 241, the film on the outer side of the horizontal bar 61 is compacted, and the film above and below the outer side is pressed against the top and bottom surfaces of the horizontal bar 61; then the horizontal bar 61 passes through the third working groove 2431 of the third impression roller 243, the film on the bottom surface is compacted, and the film on the inner side of the bottom surface is pressed against the inner side of the horizontal bar 61; the horizontal bar 61 passes through the second working groove 2421 of the second impression roller 242, the film on the top surface is compacted, and the film on the inner side of the top surface is pressed against the inner side of the horizontal bar 61. Since the film pasting parts on both sides of the film pasting machine 2 are symmetrically arranged, the above-mentioned film pasting process occurs symmetrically on the horizontal bar 62 on the other side of the fence. The rear end of the fence 6 pasted with film passes between a set of second limiting rollers 23 and the conveying roller to ensure the stability of the overall movement of the fence 6. The fence 6 pasted with film continues to be transported backward and enters the shearing conveying rack 7. When the rear end of the horizontal bar 61 just passes where the heating wire is located, the L-shaped lifting arm 72 descends, and the heating wire cuts the film, and the film pasting process of one fence 6 is completed.

[0069] (3) Unloading: The fence 6 is transferred backward from the shearing conveyor rack 7 to the unloading conveyor rack 5. The rear section of the unloading conveyor rack 5 is located below the front section of the unloading machine 3. Another finished material frame is located below the rear section of the unloading machine 3. The finished material frame is transferred to the rear section of the unloading conveyor rack 5 after passing through the film-applied fence 6. At this time, the third servo motor 323 drives the third mounting plate 322 to move to the front section of the unloading transverse moving bracket 312. The fourth servo motor 333 drives the unloading transmission rod 331 to move downward. At the same time, the unloading clamping cylinder 343 drives the unloading clamping plate 3 44 is pushed to both sides and is larger than the overall width of the fence 6. When the unloading longitudinal movement limit electric eye 335 senses that the unloading clamping plate 344 can just clamp the fence 6, the unloading transmission rod 331 stops moving, and the loading clamping plate 344 is pulled back inward to clamp the outer side of the fence horizontal bar 61. The unloading transmission rod 331 moves upward to clamp the fence 6 from the unloading conveyor rack. At the same time, the third servo motor 323 drives the unloading lateral movement mechanism and the unloading longitudinal movement mechanism to move backward as a whole to the rear section of the unloading lateral movement bracket 312, as shown in FIG. Figure 16 As shown, the fence is then lowered onto the finished material frame in the opposite manner to the above process, completing the unloading process of one fence 6. Different from the loading process, during the downward movement of the unloading gripping hand, the fence in the unloading process is misaligned with the fence already placed on the finished material frame according to the cooperation between the unloading longitudinal limit electric eye 335 and the fine adjustment sliding assembly. The misalignment method is as follows: Figure 18 As shown, the left and right sides are staggered by a distance of about the width D2 of the horizontal bar 61 .
