Description

[0001] This application is a divisional application of a patent application with the patent application number "202111675285.5", the application date of "December 31, 2021", and the title of "A Membrane Roll Suspension Packaging System". Technical Field

[0002] The present invention relates to the technical field of membrane roll packaging, and particularly to a membrane roll suspension packaging system. Background Art

[0003] The coil material is a cylindrical plastic film roll. After the coil material is manufactured, it needs to be transported to various places for sale. In order to protect the integrity of the coil material during transportation, reduce wear, and increase the transportation quantity, it is necessary to carry out suspension packaging for the coil material. Suspension packaging can be understood as first independently packaging a single coil material, covering the surface of the coil material with bubble film, then using a paper cover and a foam pad to buckle the two ends and fixing them with tape winding; then installing support clamping plates at both ends of the coil material, and then bundling the two support clamping plates, so that the coil material is suspended between the two support clamping plates. At present, the suspension packaging of coil materials in this industry is mainly manual packaging, with the help of a crane for packaging. The use of manual packaging has very low efficiency, seriously reduces the overall productivity, requires a large amount of labor, has high production costs, and low automation.

[0060] The present invention provides a film roll suspension packaging system. To make the purpose, technical solution and effects of the present invention clearer and more definite, the following further describes the present invention in detail with reference to the accompanying drawings and by way of examples. It should be understood that the specific examples described herein are only used to explain the present invention and are not used to limit the protection scope of the present invention.

[0061] In this article, "left" is the direction of film roll transportation, that is, Figure 2 the direction indicated by the arrow in

[0062] Please refer to Figures 1 - 41, the present invention provides a film roll suspension packaging system, which includes a frame y, a film conveying input line a, a first film roll handling device b, a film wrapping device c, a second film roll handling device d, a fastening device e, a feeding device f, a bundling device g, a film roll flipping and handling device h, and a wooden pallet conveying device j that are sequentially arranged on the frame y from right to left; the fastening device e is connected to the bundling device g through a film conveying trolley m; a stacking station j5 is arranged on the wooden pallet conveying device j. The film roll suspension packaging system is controlled by a film roll packaging control system to work.

[0063] During operation, the film roll P1 formed by a winding machine or a slitting machine is transported to the film roll suspension packaging system through the film conveying input line a. The first film roll handling device b first transports the film roll P1 on the film conveying input line a to the film wrapping device c, and then the film wrapping device c automatically performs film wrapping treatment on the circumferential surface of the film roll. Subsequently, the second film roll handling device d transports the film roll after film wrapping to the fastening device e. At this time, the feeding device f automatically transports the support splint p2 and the plug p3 to the fastening device e. Then the fastening device e installs the plug p3 and the support splint p2 at both ends of the film roll. The second film roll handling device d then transports the film roll to the film conveying trolley m, and the film conveying trolley m transports the film roll to the bundling device g. The bundling device g bundles the two support splints p2, so that the film roll p1 is firmly suspended between the two support splints p2; then the film conveying trolley m drives and moves to the left, and the film roll flipping and handling device h removes the film roll from the film conveying trolley m. The film roll flipping and handling device h drives the film roll p1 to complete a 90° flip, so that the bundling belt p5 located between the two support splints p2 is flipped from the original top and bottom of the support splint p2 to the left and right sides of the support splint p2, avoiding damage and breakage of the bundling belt p5 due to extrusion during stacking; at the same time, the wooden pallet conveying device j transports an empty wooden pallet adapted to the film roll to the stacking station j5. Finally, the film roll flipping and handling device h transports the film roll after suspension packaging smoothly and accurately to the wooden pallet at the stacking station. Then the fixing part installation device k installs the fixing part k9 on the top of the support splint. The film roll packaging control system repeats the above process according to the set number of film rolls in each film roll stack to achieve the stacking of film rolls. The film roll stack after stacking is transported away from the stacking station through the wooden pallet conveying device j, and further labeled and peripherally wrapped with film, waiting for forklift handling and shipment.

[0064] Compared with the prior art, the various devices in the film roll suspension packaging system cooperate with each other to complete the handling and suspension packaging operations of the film roll fully automatically. The film roll packaged by the film roll suspension packaging system is protected on its circumferential surface and at the end, ensuring that the film material is not damaged during transportation; it greatly improves the production efficiency and packaging quality, and reduces the use of labor and production costs.

[0065] Specifically, both the first film roll handling device b and the second film roll handling device d are film roll grippers that slide in the left-right direction. In this embodiment, the film roll gripper uses gears to drive the gears on two gripping arms to open and close, so as to transfer the film roll.

[0066] Specifically, the film wrapping device c feeds the packaging film into the film wrapping device c through the upper film mechanism c3000. The film pulling mechanism c2100 includes a film pulling driver c2120 arranged in the front-back direction and a film pulling claw c2110 driven by the film pulling driver c2120. The film pulling claw c2110 moves between a gripping position and a releasing position.

[0067] The roll film mechanism c2200 includes a roller driver c2210 arranged on the frame y, a first roll support roller c2220 and a second roll support roller c2230 that are rotatably mounted on the frame y. The first roll support roller c2220 and the second roll support roller c2230 are located between the gripping position and the releasing position. The roller driver c2210 is drivingly connected to the first roll support roller c2220.

[0068] After the film wrapping device c configures the film pulling mechanism c2100 to automatically pull the packaging film above the first roll support roller c2220 and the second roll support roller c2230 and spread it out, the sticky side of the packaging film faces upward. Then, the film roll is transferred between the first roll support roller c2220 and the second roll support roller c2230 by a manipulator and the packaging film is pressed below. Starting the roller driver c2210 to rotate can adhere the packaging film to the film roll p1. The film wrapping device c realizes automatically ensuring the film roll, improving safety and efficiency.

[0069] Specifically, the use process of this film wrapping device is as follows: First, prepare a packaging film with a sticky surface. For example, a layer of adhesive film is pre-covered on the upper surface of kraft paper. The film pulling claw c2110 pulls the packaging film with the upper surface covered with glue to the release position and releases it at the grasping position. At this time, the packaging film is placed on the first film supporting roller c2220 and the second film supporting roller c2230. The film roll is placed above the packaging film through a mechanical claw. At this time, the film roll is adhered to the upper surface of the packaging film. Start the roller driver c2210 to drive the film roll to rotate through the first film supporting roller c2220, and the packaging film can be wrapped around the film roll and adhered to the film roll. The action of the roller driver c2210 driving the film roll to rotate can rotate the film roll in one direction after placing it on the packaging film until the packaging film completely wraps the film roll. It can also first rotate forward several circles in one direction, and then reverse the rotation of the roller driver c2210 until the packaging film completely wraps the film roll. The method of first rotating forward and then reversing can ensure that a section of the packaging film is firmly adhered to the film roll, avoiding the film roll from separating at the position where the packaging film is placed when the packaging film is wrapped later. The film pulling driver c2120 is a rodless cylinder in this embodiment. In other embodiments, the film pulling driver c2120 can be a pneumatic push rod, an electric push rod, a hydraulic push rod, a linear module, a linear guide module, a lead screw assembly, etc. Its main effect is to provide an output end for linear motion.

[0070] Further, the film winding mechanism c2200 further includes a placement table c2240. The placement table c2240 is arranged on the frame y. The top surface of the placement table c2240 is a placement surface. A relief hole is provided in the middle of the placement table c2240. The relief hole is located below the film pulling claw c2110. The first film supporting roller c2220 and the second film supporting roller c2230 communicate with each other below the relief hole. By arranging the placement table c2240 among the film pulling claw c2110, the first film supporting roller c2220 and the second film supporting roller c2230 components, and the film pulling claw c2110 pulling the packaging film to the placement table c2240 for placement, the flatness of the spread of the packaging film can be improved, and the accuracy of adhesion of the film pulling claw c2110 can be improved. Specifically, two sets of film pulling mechanisms c2100 are provided, and the two sets of film pulling mechanisms c2100 are respectively located on both sides of the film winding mechanism c2200.

[0071] Further, the film wrapping device c further includes a film wrapping mechanism c2300. The film wrapping mechanism c2300 includes a film wrapping lifting table c2310 that is liftably provided on the frame y, a first film wrapping rod c2320 rotatably connected to the film wrapping lifting table c2310, a second film wrapping rod c2330 rotatably connected to the film wrapping lifting table c2310 on the film wrapping lifting table c2310, and a film wrapping driver that drives the first film wrapping rod c2320 and the second film wrapping rod c2330 to move away from or close to each other. The first film wrapping rod c2320 and the second film wrapping rod c2330 are respectively located on both sides of the first film roll supporting roller c2220 and the second film roll supporting roller c2230. The film wrapping lifting table c2310 drives the first film wrapping rod c2320 and the second film wrapping rod c2330 to move back and forth on both sides of the first film roll supporting roller c2220. By configuring the film wrapping mechanism c2300, the film wrapping device c can also wrap the film roll in a clamping manner to adapt to the packaging requirements of different packaging film materials. The working principle of the film wrapping mechanism c2300 is as follows: Before use, first place the packaging film and the film roll on the first supporting roller and the second supporting roller, then the film wrapping lifting table c2310 drives the first film wrapping rod c2320 and the second film wrapping rod c2330 to rise, lift both sides of the packaging film above the film roll, and then the film wrapping driver drives the first film wrapping rod c2320 and the second film wrapping rod c2330 to move closer to each other to close the packaging film, completing the packaging of the film roll. After the packaging film is closed, the connection between both sides of the packaging film can be achieved by pre-coating glue on the packaging film or by heat melting the two sides of the packaging film together.

[0072] Further, the film wrapping mechanism c2300 further includes a first connecting rod c2321 and a first guide base c2322. The first guide base c2322 is arranged on the frame y. A first guiding surface c23221 is provided on the side of the first guide base c2322 adjacent to the second film wrapping rod c2330. The first guiding surface c23221 is inclined upward in a direction away from the second film wrapping rod c2330. The first connecting rod c2321 is hinged to the film wrapping lifting table c2310. The first connecting rod c2321 swings left and right. The top of the first connecting rod c2321 is connected to the first film wrapping rod c2320. A first guide block is further provided on the first connecting rod c2321. The first guide block slides along the first guiding surface c23221. The first film wrapping rod c2320 is hinged to the film wrapping lifting table c2310 through the first connecting rod c2321. During the process of the film wrapping lifting table c2310 driving the first film wrapping rod c2320 and the first connecting rod c2321 to rise, the first guide block slides along the first guiding surface c23221, so that the first film wrapping rod c2320 swings in a direction away from the second film wrapping rod c2330 while rising, increasing the span between the first film wrapping rod c2320 and the second film wrapping rod c2330, and expanding the maximum diameter of the film roll that the film wrapping mechanism c2300 can wrap.

[0073] Further, the film wrapping mechanism c2300 further includes a second connecting rod c2331 and a second guide base c2332. The second guide base c2332 is arranged on the frame y. A second guide surface c23321 is provided on the side of the second guide base c2332 adjacent to the second film wrapping rod c2330. The second guide surface c23321 is inclined upward in a direction away from the second film wrapping rod c2330. The second connecting rod c2331 is hinged to the film wrapping lifting table c2310. The second connecting rod c2331 swings left and right. The top of the second connecting rod c2331 is connected to the second film wrapping rod c2330. A second guide block is further provided on the second connecting rod c2331. The second guide block slides along the second guide surface c23321. The functions of the second connecting rod c2331, the second guide base c2332, and the second guide block are similar to those of the first connecting rod c2321, the first guide base c2322, and the first guide block. The second connecting rod c2331, the second guide base c2332, and the second guide block are configured such that the second film wrapping rod c2330 swings in a direction away from the first film wrapping rod c2320 while rising, further increasing the span between the first film wrapping rod c2320 and the second film wrapping rod c2330, and expanding the maximum diameter of the film roll that the film wrapping mechanism c2300 can wrap. In addition, the first film wrapping rod c2320 and the second film wrapping rod c2330 swing in directions away from each other while rising. The lateral moving forces generated by the swinging of the first film wrapping rod c2320 and the second film wrapping rod c2330 on the packaging film can cancel each other out, reducing the lateral movement of the packaging film caused by the swinging.

[0074] In this embodiment, the film wrapping driver is a cylinder. The fixed end and the driving end of the cylinder are respectively hinged to the first connecting rod c2321 and the second connecting rod c2331.

[0075] Further, the film wrapping mechanism c2300 further includes a first driving wheel c2340, a second driving wheel, and a synchronous wheel that are all rotatably arranged on the film wrapping lifting table c2310. The first driving wheel c2340 is fixedly connected to the first connecting rod c2321. The first connecting rod c2321 is rotatably connected to the film wrapping lifting table c2310 through the first driving wheel c2340. The second driving wheel is fixedly connected to the second connecting rod c2331. The second connecting rod c2331 is rotatably connected to the film wrapping lifting table c2310 through the second driving wheel. The synchronous wheel is located between the first driving wheel c2340 and the second driving wheel, and the synchronous wheel is drivingly connected to both the first driving wheel c2340 and the second driving wheel. The synchronous wheel abuts against the first driving wheel c2340 and the second driving wheel respectively located on both sides of the synchronous wheel, which can ensure the synchronous rotation of the first driving wheel c2340 and the second driving wheel. Thus, through the first connecting rod c2321 and the second connecting rod c2331, it is ensured that the first film wrapping rod c2320 and the second film wrapping rod c2330 swing synchronously. When the first film wrapping rod c2320 and the second film wrapping rod c2330 are driven by the film wrapping driver to swing inward, that is, in the direction of approaching each other, it is ensured that the packaging film symmetrically wraps the film roll, and the degree of fit between the packaging film and the film roll is maximally ensured.

[0076] Further, the film wrapping mechanism c2300 further includes a heating member (not shown in the figure). The heating member includes a heater arranged in the first film wrapping rod c2320 and / or the second film wrapping rod c2330. By configuring the heating member and arranging the heating wire in the first film wrapping rod c2320 and / or the second film wrapping rod c2330, hot melt processing can be conveniently performed when the first film wrapping rod c2320 and the second film wrapping rod c2330 clamp the packaging film.

[0077] Further, the film wrapping mechanism c2300 further includes a lifting drive assembly. The lifting drive assembly includes a chain assembly c2352 and a lifting guide rail c2351. The chain assembly c2352 and the lifting guide rail c2351 are both arranged on the frame y. The chain assembly c2352 includes a circulating chain. The chain is arranged in the up and down direction. A lifting drive block c2353 is fixedly connected to the chain. The lifting drive block c2353 is fixedly connected to the film wrapping lifting table c2310. The film wrapping lifting table c2310 in the film wrapping mechanism c2300 is driven to lift by the chain assembly c2352, which has the advantage of low cost.

[0078] Further, the number of the film wrapping mechanisms c2300 is two groups. The two groups of film wrapping mechanisms c2300 are respectively arranged on the front side and the rear side of the first film supporting roller c2220. A film wrapping driving assembly is arranged between the two groups of film wrapping mechanisms c2300. The film wrapping driving assembly includes a film wrapping driving motor c2361, a film wrapping driving worm gear c2362, a first film wrapping driving worm c2363 and a second film wrapping driving worm c2364 arranged on the frame y. The film wrapping driving motor c2361 is drivingly connected with the film wrapping driving worm gear c2362. The film wrapping driving worm gear c2362 is in transmission connection with the first film wrapping driving worm c2363 and the second film wrapping driving worm c2364. The first film wrapping driving worm c2363 and the second film wrapping driving worm c2364 are respectively in transmission connection with the chain assemblies c2352 in the two film wrapping mechanisms c2300. Configuring two groups of film wrapping mechanisms c2300 makes the actions of the first film wrapping rod c2320 and the second film wrapping rod c2330 more balanced and stable. The chains of the two groups of film wrapping mechanisms c2300 achieve synchronous rotation through the transmission connection between the first film wrapping driving worm c2363, the second film wrapping driving worm c2364 and the film wrapping driving worm gear c2362, ensuring that the chain assemblies c2352 of the two groups of film wrapping mechanisms c2300 act in unison and lifting and lowering the first film wrapping rod c2320 and the second film wrapping rod c2330 in a balanced manner.

[0079] Both the film wrapping mechanism c2300 and the film rolling mechanism c2200 can wrap the film roll. When the film rolling mechanism c2200 wraps the film roll, it mainly relies on the glue pre-coated on the upper surface of the packaging film to bond with the film roll to keep it fixed. This is especially suitable for packaging films with a flat surface, such as kraft paper packaging films, PVC packaging films, etc. For some non-flat packaging films with an uneven surface, for example, the amount of glue that can adhere to the same area on the surface of a bubble film non-flat packaging film is less, and it is easy to have problems such as falling off when using the film wrapping mechanism c2300 to bond with the film roll. The film wrapping mechanism c2300 in the present disclosure fixes the packaging film and the film roll in a way of closing after enclosing the film roll, without pre-coating glue on the surface of the packaging film, has a lower requirement for surface flatness, and can adapt to different packaging films for packaging operations.

In addition, during use, the center support plate e3 can be arranged above the lifter e11, so that the first support plates e2 are respectively arranged on the left and right sides of the center support plate e3, and its structure is compact.

[0088] In addition, in actual use, in order to automatically buckle and support the clamping plates p2 and the plugs p3 at both ends of the film roll, it is necessary to position the center of the film roll. When the center of the film roll has been positioned, the setting of the center support plate e3 facilitates the placement of the film roll.

[0089] In some embodiments, the highest point of the stroke of each of the first support plates e2 is flush with the center support plate e3. This structure is simple and convenient to set. Through the setting of this structure, it is ensured that the first support plate e2 and the center support plate e3 are flush when supporting the film roll, avoiding damage caused by excessive stress received by a local part of the side of the film roll due to the height difference between the first support plate e2 and the center support plate e3.

[0090] In some embodiments, the lifting assembly e1 includes a lifter e11 arranged on the first support frame e0, a guide rod e12 arranged on the first support frame e0, a lifting slider e13 slidably engaged with the guide rod e12, and a connecting frame e14 fixedly connected to the lifting slider e13.

The connecting frame e14 extends to the left and right sides with the lifting slider e13 as the center. The first support plates e2 are symmetrically arranged on both the left and right sides of each connecting frame e14. This structure is simple and convenient to set. All the lifters e11 are arranged in the front-back direction, and each connecting frame e14 extends to the left and right sides with the corresponding lifting slider e13 as the center, which is convenient to be set into a symmetrical structure, making the structure more stable. In addition, the lifters e11 are arranged in the front-back direction, so as to realize the interval between adjacent connecting frames e14 and play a role in avoiding interference between adjacent connecting frames e14.

[0091] In actual use, in each lifting assembly e1, preferably, two guide rods e12 are provided, and the lifter e11 is arranged between the two guide rods e12. In some embodiments, in each lifting assembly e1, the two guide rods e12 are arranged in the left-right direction.

[0092] Since all the first support plates e2 extend in the left-right direction, the length of each connecting plate extending should be adapted to the positions of the corresponding two first support plates e2. Preferably, the two first support plates e2 symmetrically arranged on the same connecting frame e14.

[0093] In some embodiments, the lifter e11 is an electric cylinder or a rodless cylinder. Optionally, a rodless cylinder is adopted in this embodiment.

The first support frame e0 is fixed on the lifting mechanism e5, and the lifting mechanism e5 drives the first support frame e0 to reciprocate in the up and down direction.

[0095] In actual use, in order to fasten the plug p3 and the support clamp p2 to the film roll, it is necessary to fix the position of the center of the film roll to accurately position the center of the film roll, so as to realize the fastening and installation of the plug p3 and the support clamp p2. When the film rolls with different diameters are placed flat, the height of the center position of the film roll is different, so it is necessary to adjust the height of the film roll.

[0096] Therefore, by driving the first support frame e0 to move in the up and down direction by the lifting mechanism e5, the height of the film roll supported by the first support plate e2 and the center support plate e3 can be adjusted, thereby realizing the adjustment of the height of the center of the film roll.

[0097] In some embodiments, a first recess e20 extending in the left-right direction is formed in the middle of the center support plate e3, and a second recess e30 extending in the left-right direction is formed in the middle of the first support plate e2. The first recess e20 and the second recess e30 are opposite to each other. This structure is simple and convenient to set. Through the setting of the recess, the film roll disposed in the first recess e20 and the second recess e30 can be limited to prevent the film roll from easily rolling and falling. In addition, through the setting of the first recess e20 and the second recess e30, the contact area between the side surface of the film roll and the first recess e20 and the second recess e30 can be effectively increased, thereby reducing the stress of the compressed part of the film roll and avoiding damage to the film roll.

The vertical electric lead screw e53 drives the vertical slide block e52 to reciprocate in the up and down direction. By driving the vertical slide block e52 to reciprocate in the up and down direction by the vertical electric lead screw e53, since the vertical slide block e52 is fixedly connected to the first support frame e0, the up and down movement of the first support frame e0 can be realized.

[0100] Preferably, two vertical slide rails e51 are provided, and a vertical electric lead screw e53 is arranged between the two vertical slide rails e51. The vertical slider e52 is slidably engaged with the two vertical slide rails e51 at the same time. Its structure is more stable.

[0104] In use, the user can first place the plug p3 on the first plug mounting shaft e9, pass the first plug mounting shaft e9 through the through hole e61 on the support clamping plate e63, and tension the through hole e61 through the expansion of the expansion assembly e10, so as to realize the positioning of the through hole e61. Drive the first plug mounting shaft e9 to move in the left-right direction through the material pushing assembly e011, and adjust the relative position between the suction cup e8 and the first plug mounting shaft e9. Thus, the support clamping plate p2 is fixed by using the suction cup e8. After fixing the support clamping plate p2, the expansion assembly e10 releases the through hole e61. The user can move the film roll to the left relative to the first plug mounting shaft e9, so that the first plug mounting shaft e9 is inserted into the core. However, the expansion assembly e10 expands again to realize the positioning of the core of the film roll and fine-tune the film roll to achieve centering, ensuring that the through hole e61 on the support clamping plate e63 and the center of the core are concentric, so that the plug p3 on the first plug mounting shaft e9 can be smoothly inserted into the through hole e61 and the core to achieve buckling.

[0105] Preferably, a plurality of the suction cups e8 are provided, and all the suction cups e8 are circumferentially and arrayed around the axis of the first plug mounting shaft.

[0106] In some embodiments, an avoidance hole e70 is formed in the fixing plate e7, and the avoidance hole e70 is used for the first plug mounting shaft to pass through. Through the setting of this structure, it is convenient for the expansion assembly e10 on the first plug mounting shaft to tension the through hole e61 on the support clamping plate p2 to realize positioning and centering.

[0107] In some embodiments, a cavity is formed in the first plug mounting shaft e9, the expansion assembly e10 is disposed in the cavity, a plurality of openings e90 are formed in the side surface of the first plug mounting shaft, the expansion assembly e10 includes a pusher e101 fixedly connected to the first plug mounting shaft, an inner push shaft e103 disposed in the cavity, and a plurality of jaw blocks e102 disposed on the push shaft e103. The movable part of the pusher e101 is fixedly connected to the push shaft e103. The jaw blocks e102 are disposed in the openings e90, and the jaw blocks e102 are slidably engaged with the openings e90. The openings e90 and the jaw blocks e102 are arranged in one-to-one correspondence. A plurality of card slots e1031 are formed in the push shaft e103, the depth of the card slots e1031 gradually increases in the direction close to the film roll support device e17, a convex rib e1032 is provided on the inner wall of the card slot e1031, and the extending direction of the convex rib e1032 is arranged along the extending direction of the depth of the card slot e1031. The convex rib e1032 and the card slot e1031 are respectively in concave-convex fit with the jaw block e102, and the jaw block e102 is in sliding fit with the card slot e1031, and the jaw block e102 is in sliding fit with the convex rib e1032. This structure is simple and convenient to set. The expansion assembly e10 is disposed in the cavity, and its structure is compact, which can reduce the weight of the plug e64 mounting shaft.

[0108] When the pusher e101 drives the push shaft e103 to move in the direction close to the film roll support device e17, the jaw block e102 is pushed out in the depth direction of the opening e90 away from the axis of the first plug mounting shaft along with the decrease of the depth of the card slot e1031 under the limiting action of the convex rib e1032, realizing the tightening action.

[0109] When the pusher e101 drives the push shaft e103 to move in the direction away from the film roll support device e17, the clamp block retracts into the cavity in the depth direction of the opening e90 close to the axis of the first plug mounting shaft along with the increase of the depth of the card slot e1031 under the limiting action of the convex rib e1032, realizing the loosening action.

[0110] In some embodiments, the end surface of the jaw block e102 away from the axis of the first plug mounting shaft is provided as an inclined surface, and the height of the inclined surface gradually increases from right to left. Through the setting of this structure, it is convenient to guide during the process of inserting into the through hole e61 or the core.

[0111] In some embodiments, a flange e91 is provided on the first plug mounting shaft e9, and the flange e91 is used to abut against a plug e64 provided on the first plug mounting shaft. The opening e90 is provided between the flange e91 and the film roll support device e17. Through the arrangement of the flange e91, it is convenient to abut against the end face of the plug e64 facing away from the film roll support device e17, so that under the action of the left and right driving device e16 driving the fastening head e18 to move, after the first plug mounting shaft is inserted into the through hole e61 and the core of the support clamping plate e63, the plug e64 is inserted into the through hole e61 and the core.

[0112] In some embodiments, a second plug mounting shaft e012 is provided on the end face of the first plug mounting shaft close to the film roll support device e17. The outer diameter of the second plug mounting shaft is smaller than the outer diameter of the first plug mounting shaft, and the second plug mounting shaft is used to mount the plug e64.

[0113] Preferably, the opening e90 is provided between the second plug mounting shaft and the flange e91.

[0114] For some with smaller apertures, such as Figure 9 As shown, for example, when using a three-inch small plug p32 for fastening, the corresponding sized plug p3 can be directly inserted through the second plug mounting shaft and directly fastened and installed into the through hole e61 and the core that are adapted to the size of the plug p3. Since the size of the plug p3 is small, the interference area caused by the deviation is small, and the damage to the film roll caused by forced insertion is small. Moreover, when forcedly inserted into the core and the through hole e61, the through hole e61 and the core can be centered under the guiding action of the plug p3 itself. Therefore, the expansion assembly e10 can be not adopted. As Figure 8 As shown, when using a six-inch large plug p31, the expansion assembly e10 needs to be adopted.

[0115] In some embodiments, the fastening frame e013 includes a main body frame e0131 and a sleeve e0132 fixed on the main body frame e0131. The fixing plate e7 is fixedly connected to the sleeve e0132 through a transition frame e0133.

With this structure, it is convenient to control the distance of the left - right sliding of the first plug mounting shaft, so that the user can adjust the relative position between the first plug mounting shaft and the suction cup e8 according to different film roll sizes, and it is convenient to position the through - hole e61.

[0117] The loading device f includes a gantry f18, a first transverse movement mechanism f16, a second transverse movement mechanism f17, a clamping plate gripper f12, a plug gripper f103 and a feeding device; the first transverse movement mechanism f16 is arranged on the gantry f18; the second transverse movement mechanism f17 is arranged on the gantry f18; the clamping plate gripper f12 is arranged on the first transverse movement mechanism f16, and the first transverse movement mechanism f16 drives the clamping plate gripper f12 to reciprocate in the left - right direction; the plug gripper f103 is arranged on the second transverse movement mechanism f17, and the second transverse movement mechanism f17 drives the plug gripper f103 to reciprocate in the left - right direction; the feeding device is arranged beside the gantry f18, and the feeding device is arranged within the working space of the plug gripper and the clamping plate gripper. The feeding device is used to place a plurality of support clamping plates p2 stacked and position the support clamping plates p2 in terms of length or width. The feeding device is used to stack the plugs p3 and restrict the radial degrees of freedom of the plugs p3.

[0118] From the above, during use, the film roll f62 to be packaged can be horizontally arranged on an external support frame. A plurality of support clamping plates p2 are placed on the feeding device and stacked, and by positioning the support clamping plates p2 in terms of length or width, it is convenient for the clamping plate p2 gripper to position and clamp the clamping plate p2. In addition, the feeding device is used to stack the plugs p3 and restrict the radial degrees of freedom of the plugs p3, which is convenient for the plug p3 gripper to grasp the plugs p3. At the same time, with the arrangement of the first transverse movement mechanism f16 and the second transverse movement mechanism f17, it is convenient to transfer the clamping plate p2 gripper and the plug p3 gripper, so as to install the clamped clamping plate p2 and plug p3 onto the film roll f62 after grasping.

[0119] Specifically, the bundling device g includes a first three-axis drive structure g2 disposed on the frame y, a tape-running frame g3 disposed on the first three-axis drive structure g2, a bundling head g4 disposed around the tape-running periphery, and a tape storage assembly for supplying bundling tapes to the bundling head g4 and the tape-running frame g3. The bundling head g4 is used to cooperate with the tape-running frame to bundle the articles in the tape-running frame g3. A centering and clamping mechanism g7 for pushing two support clamping plates to clamp the film roll is provided on the frame y.

[0120] After the film roll is buckled with the upper support clamping plate and the plug, the film roll is transported to the bundling station g6 by the film transporting trolley m for suspended bundling. Then, the centering and clamping mechanism g7 pushes the film roll to be centered and positioned and pushes the two support clamping plates to clamp the ends of the film roll. At this time, the tape-running frame g3 is lifted to the highest position (i.e., the initial position) by the three-axis drive structure, and the film roll is located directly below the tape-running frame g3 to avoid collision with the film roll. Then, the first three-axis drive structure g2 first drives the tape-running frame g3 to move in front of the film roll, and then the first three-axis drive structure g2 drives the tape-running frame g3 to descend to a suitable height according to the diameter of the film roll. Then, the first three-axis drive structure g2 drives the tape-running frame g3 to move backward, so that the front ends of the two support clamping plates pass through the tape-running frame g3. The bundling head g4 is used to draw the bundling tape into the tape-running frame g3. After the bundling tape goes around the tape-running frame g3 for one circle, the overlapping part of the bundling tape and the bundling tape head is butted, and the bundling tape is pulled back, so that the bundling tape p5 tightly binds the two support clamping plates p2. The bundling head g4 heat-seals the butted part of the bundling tape and the bundling tape head, and finally cuts the bundling tape to complete the automatic bundling on the front side of the film roll.

[0121] To further improve the reliability of bundling, the first three-axis drive structure g2 will reset to the initial position, and then the first three-axis drive structure g2 drives the tape-running frame g3 to the rear of the film roll. Then, the first three-axis drive structure g2 drives the tape-running frame g3 to descend to a suitable height. Then, the first three-axis drive structure g2 drives the tape-running frame g3 to move forward, so that the rear ends of the two support clamping plates p2 pass through the tape-running frame g3. The bundling head g4 then performs automatic bundling on the rear side of the film roll. After the film roll is bundled on the front and rear sides, it is ensured that the support clamping plates p2 are closely attached to the film roll to prevent the support clamping plates p2 from detaching from the film roll. Finally, the centering and clamping mechanism g7 releases the film roll, and the film transporting trolley m removes the bundled film roll from the bundling station g6, and the transportation process is stable.

[0122] Furthermore, the centering clamping mechanism g7 includes two clamping assemblies g71 symmetrically arranged on the frame y, each clamping assembly g71 includes a casing g711 fixedly connected to the frame y, an electric push rod g712 arranged on the casing g711, and a pressure plate g713 vertically arranged on one side of the casing g711; a pressure sensor g714 is arranged at the output end of the electric push rod g712, and the pressure sensor g714 is transmission-connected to the pressure plate g713, and the electric push rod g712 is used to drive the pressure sensor g714 and the pressure plate g713 to move back and forth laterally. After the supporting plates are installed on both ends of the film roll, the film roll is transported to the bundling station g6. At this time, the two clamping components g71 work synchronously and automatically. Each of the electric push rods g712 drives the pressure plate g713 to move toward the supporting plate. The two pressure plates g713 jointly push the film roll to move, so that the film roll is centered. During the pushing process, the supporting plate generates a reaction force on the pressure plate g713. At this time, the pressure sensor g714 can feed back the value of the reaction force to the control system. Assume that the reaction force value is relatively large (such as 50N). After the film roll is centered, the two pressure plates g713 continue to press the supporting splints against the film roll, and then the reaction force gradually increases until the reaction force value fed back by the pressure sensor g714 is equal to the preset value, which means that the pressure plate g713 firmly presses the supporting splints against the end of the film roll. The control system controls the electric push rod g712 to stop moving, and the two supporting splints jointly clamp the film roll to ensure that the strapping tape is tighter and more secure when bundling the two supporting splints.

[0123] Specifically, the film roll flipping and transporting device h includes a slide h2 slidably arranged on the frame y, a front and rear driving assembly h3 for driving the slide h2 to move forward and backward, a lifting frame h4 slidably arranged on the slide h2, a lifting driving assembly h5 for driving the lifting frame h4 to move up and down, two flipping grippers h6 slidably arranged at the bottom of the lifting frame h4, and a grabbing driving mechanism h7 for driving the two flipping grippers h6 to move closer to or away from each other; the two flipping grippers h6 are used to clamp the film roll and flip the film roll.

[0124] After the film roll is suspended and packaged, it is transported from the bundling station to the grabbing station by the film transport trolley m. At this time, the film roll is located between the two flip grippers h6. Since the upstream equipment has learned the diameter of the film roll, the two flip grippers h6 are driven by the lifting drive component h5 and the front and rear drive component h3 to align with the film roll. Then the grabbing drive mechanism h7 drives the two flip grippers h6 to move toward the film roll. After the two flip grippers h6 clamp the film roll, the lifting drive component h5 drives the film roll on the flip gripper h6 to move up, so that the film roll is separated from the film transport trolley. Trolley m; then the front and rear drive components h3 drive the film roll on the flip gripper h6 to move toward the stacking station. During the movement, the flip gripper h6 drives the film roll to automatically complete a 90° flip, so that the strapping belt between the two supporting splints is flipped from the top and bottom of the supporting splint to the left and right sides of the supporting splint p2, to avoid the strapping belt being squeezed and damaged and broken during stacking. Finally, the lifting drive component h5 drives the film roll on the flip gripper h6 down to the stacking station, and the two flip grippers h6 move away from each other to release the film roll.

[0125] The film roll flipping and transporting device h can automatically complete the film roll transport and flipping. The two flipping grippers h6 are driven by the grabbing drive mechanism h7 to grab the film roll, and the film roll is transferred to the work station under the drive of the front and rear drive components h3 and the lifting drive component h5. The flipping operation of the film roll is completed synchronously during the transport process. It is efficient and fast, does not require staff to assist in the transport, and has a high degree of automation.

[0126] Specifically, the flip gripper h6 includes a hanging bracket h61 slidingly connected to the bottom of the lifting frame h4, a positioning shaft h62 rotatably arranged on the hanging bracket h61, a flip driving device h63 transmission connected to the positioning shaft h62, and a pressure plate h622 fixed on the positioning shaft h62; the positioning shaft h62 is sleeved with a positioning round head h65 which can move axially relative to it, the pressure plate h622 is provided with an in-position sensor h661, and the positioning round head h65 is provided with a round head in-position contact piece for triggering the in-position sensor h661; a plurality of elastic limiting mechanisms h67 for limiting the moving stroke of the positioning round head 65 are arranged between the positioning round head h65 and the pressure plate h622; a plurality of flip anti-skid components h68 are arranged on the pressure plate h622, and the flip anti-skid components h68 are used to keep the supporting splint and the pressure plate h622 relatively still.

[0127] If the film roll is suspended and packaged using a small plug p32 (the diameter of the plug is 3 inches), the positioning rotating shaft h62 is inserted into the center of the small plug p32. The positioning rotating shaft h62 has a clearance fit with the small plug p32. The positioning rotating shaft h62 supports the film roll. The clamping end face of the positioning round head h65 abuts against the peripheral edge protrusion of the small plug p32. As the flipping gripper h6 continues to move towards the center of the film roll, the elastic limiting mechanism h67 provides a thrust to the positioning round head h65, so that the clamping end face of the positioning round head h65 always presses against the peripheral edge protrusion of the small plug p32 during the process of the pressing plate h622 gradually approaching the positioning round head h65. At the same time, all the flipping anti-slip components h68 press against the supporting clamping plate, increasing the friction between the film roll and the flipping gripper h6, ensuring that the film roll and the flipping gripper h6 remain relatively stationary during the subsequent flipping process of the film roll and do not slip. When the in-place sensing mechanism h66 senses that the pressing plate h622 has moved in place, it means that the two positioning round heads h65 clamp the two small plugs p32 (i.e., the flipping gripper h6 clamps both ends of the film roll), and the flipping gripper h6 successfully grabs the film roll. Then the film roll is moved away from the transport trolley and towards the palletizing station. During the movement, the flipping drive device h63 drives the positioning rotating shaft h62 and the pressing plate h622 to rotate, thereby driving the film roll to complete a 90° flip, so that the strapping band located between the two supporting clamping plates flips from the original top and bottom of the supporting clamping plate to the left and right sides of the supporting clamping plate, avoiding damage and disconnection of the strapping band due to extrusion during palletizing. Finally, the film roll is placed at the palletizing station, and the two flipping grippers h6 move away from each other and release the film roll.

[0128] If the film roll is packaged in suspension using a large plug p31 (the diameter of the plug is 6 inches), the positioning round head h65 is inserted into the center of the large plug p31. The large plug p31 is sleeved on the positioning round head h65. The positioning round head h65 plays a supporting role for the large plug p31. The edge h652 of the positioning round head h65 abuts against the peripheral edge protrusion of the large plug p31. As the flipping gripper h6 continues to move towards the center of the film roll, the elastic limiting mechanism h67 provides a thrust to the positioning round head h65, so that the edge h652 of the positioning round head h65 is always pressed against the peripheral edge protrusion of the large plug p31 during the process of the pressing plate h622 gradually approaching the positioning round head h65. At the same time, all the flipping anti-slip components h68 press against the supporting clamping plate, increasing the friction between the film roll and the flipping gripper h6, ensuring that the film roll and the flipping gripper h6 remain relatively stationary during the subsequent flipping process and do not slip. When the in-place sensing mechanism h66 senses that the positioning round head h65 has moved in place, it means that the two positioning round heads h65 clamp the two large plugs p31 (i.e., the flipping gripper h6 clamps both ends of the film roll), and the flipping gripper h6 successfully grabs the film roll. Then the film roll is moved away from the transport trolley and towards the palletizing station. During the movement, the flipping drive device h63 drives the positioning rotating shaft h62 and the pressing plate h622 to rotate, thereby driving the film roll to complete a 90° flip, so that the binding belt p5 located between the two supporting clamping plates p2 is flipped from the original top and bottom of the supporting clamping plate p2 to the left and right of the supporting clamping plate p2, avoiding damage and breakage of the binding belt due to extrusion during palletizing. Finally, the film roll is placed at the palletizing station, and the two flipping grippers h6 move away from each other and release the film roll.

[0129] Specifically, the elastic limiting mechanism h67 includes a first guide sleeve h671 fixedly arranged on the pressing plate h622, a first guide rod h672 slidably connected with the first guide sleeve h671, and a first spring h673 sleeved on the first guide rod h672. The first guide sleeve h671 is arranged on the end face of the pressing plate h622 facing the positioning round head h65. One end of the first spring h673 presses against the first guide sleeve h671, and the other end presses against the positioning round head h65. The first guide rod h672 passes through the pressing plate h622. One end of the first guide rod h672 is fixedly connected with the positioning round head h65, and the other end limits the first guide rod h672 to break away from the pressing plate h622. In the normal state, the first spring h673 is expanded, keeping the maximum distance between the positioning round head h65 and the pressing plate h622. The limiting round plate limits the first guide rod h672 to break away from the pressing plate h622. When the positioning round head h65 is squeezed by the plug, the positioning round head h65 moves towards the pressing plate h622, and the first spring h673 is gradually compressed, applying an elastic thrust to the positioning round head h65 to ensure that the two positioning round heads h65 can clamp the film roll.

[0130] In this embodiment, a plurality of elastic limiting mechanisms h67 are provided and are reasonably arranged between the positioning round head h65 and the pressing plate h622. On the one hand, it ensures that the forces on each part of the positioning round head h65 are evenly distributed. On the other hand, it ensures that the clamping force of the positioning round head h65 on the film roll is sufficient, ensuring that the film roll will not shift or become loose during the movement and flipping processes.

[0131] Further, the flipping anti-slip assembly h68 includes a second guide sleeve h681 fixed on the pressing plate h622, a second guide rod h682 slidably connected to the second guide sleeve h681, and a second spring h683 sleeved on the second guide rod h682. The second guide rod h682 passes through the pressing plate h622. One end of the second guide rod h682 is provided with a pressing head h684, and the other end limits the second guide rod 682 from detaching from the pressing plate h622. Dense spikes h685 are arranged on the pressing head h684. One end of the second spring h683 abuts against the second guide sleeve h681, and the other end abuts against the pressing head h684. Under the elastic force of the second spring h683, the spikes h685 on the pressing head h684 pierce into the wooden support splint, forming a good gripping force. Compared with setting an anti-slip gasket on the pressing head h684, it can better improve the anti-slip performance of the film roll flipping; in addition, the second guide rod h682, the pressing head h684, and the spikes h685 can be integrally formed by casting, which is strong and durable and not easily deformed.

[0132] Preferably, the end of the positioning rotating shaft h62 away from the flipping driving device h63 is of a truncated cone structure; by setting it like this, a guiding conical surface h621 can be formed on the positioning rotating shaft h62, and the guiding conical surface h621 guides the positioning rotating shaft h62 to insert into the small plug p32, reducing the assembly difficulty and ensuring that the positioning rotating shaft h62 can be smoothly inserted into the small plug p32. The positioning round head h65 includes a round head main body h651 with a hollow structure and a retaining edge h652 provided on the peripheral wall of the round head main body h651. The middle part of the round head main body h651 is slidably connected to the positioning rotating shaft h62, the peripheral wall of the round head main body h651 cooperates with the inner wall of the large plug p31, and the retaining edge h652 fits with the peripheral edge protrusion of the large plug p31 to form an axial positioning for the large plug p31.

[0133] Preferably, a plug anti - detachment structure h64 is provided on the pressing plate h622. The plug anti - detachment structure h64 includes a third guide sleeve h641 fixedly arranged on the pressing plate h622, a third guide rod h642 slidably connected to the third guide sleeve h641, and a third spring h644 sleeved on the third guide rod h642. The third guide rod h642 passes through the pressing plate h622. One end of the third guide rod h642 is provided with a head h643 that abuts against the large plug p31, and the other end limits the third guide rod h642 from detaching from the pressing plate h622. One end of the third spring h644 abuts against the third guide sleeve h641, and the other end abuts against the head h643. When the flipping gripper h6 grabs the film roll, the positioning rotating shaft h62 is tightly connected to the small plug p32. Similarly, the positioning round head h65 is tightly connected to the large plug p31. When the positioning rotating shaft h62 and the positioning round head h65 pull out the plug, it is easy to take the plug away from the core. Under the elastic force of the third spring h644, the head h643 always pushes the peripheral bulge of the plug to the end of the film roll, playing a role in fixing the plug, so as to prevent the positioning rotating shaft h62 and the positioning round head h65 from taking the plug away from the core under the action of friction during the process of pulling out the film roll.

[0134] Specifically, the wooden pallet conveying device j includes an iron pallet conveying line j1 extending in the front - rear direction, and a plurality of iron slide plates j2 arranged on the iron pallet conveying line. The palletizing station j5 is arranged in the middle of the iron pallet conveying line. Each iron slide plate j2 is placed with a wooden pallet j3. The iron pallet conveying line j1 can transport the iron slide plate and the wooden pallet j3 on the iron slide plate j2 to the palletizing station j5. On both sides of the palletizing station j5, there are two groups of wooden pallet position detection devices and iron slide plate travel detection devices j42, and two pusher plate assemblies j43 arranged between the two groups of iron slide plate travel detection devices. The two pusher plate assemblies are symmetrically arranged left and right. One group of wooden pallet position detection devices and iron slide plate travel detection devices j42 is arranged at the front end of the palletizing station j5, and the other group of wooden pallet position detection devices and iron slide plate travel detection devices j42 is arranged at the rear end of the palletizing station j5. The wooden pallet position detection device, the iron slide plate travel detection device j42, and the pusher plate assembly j43 are all electrically connected to the coil packaging control system. Before palletizing, the wooden pallet j3 to be transported may be in front of or behind the palletizing station j5. Whether the wooden pallet j3 enters the palletizing station j5 from the front of the palletizing station j5 or from the rear of the palletizing station 5, there are wooden pallet position detection devices and iron slide plate travel detection devices j42 to detect the travel of the wooden pallet j3 and the iron slide plate j2, ensuring that the wooden pallet j3 accurately moves to the palletizing station j5. The iron slide plate conveying line is connected by a plurality of transportation components j11, and each transportation component is independently controlled without interference with each other.

[0135] The wooden pallet conveying device j controls the movement of the iron skid j2 through the iron skid conveying line j1, so that the iron skid j2 corresponding to the current coil and the wooden pallet j3 move to the palletizing station j5 together. When the iron skid j2 and the wooden pallet j3 enter the palletizing station j5, the iron skid travel detection device j42 detects the moving distance of the front end of the iron skid j2, and detects the triggering timing of the front end face of the wooden pallet j3 through the wooden pallet position detection device, so that the coil packaging control system automatically calculates the placement error of the iron skid j2 in the front-back direction, makes the iron skid j2 drive the wooden pallet j3 to accurately stop at the palletizing station j5, and synchronously pushes the wooden pallet j3 through two pusher assemblies j43 to further correct the left-right placement of the wooden pallet j3, ensuring that the wooden pallet j3 accurately moves to the preset palletizing station j5.

[0136] In the non-palletizing state, all iron skids j2 are away from the palletizing station j5, that is, no iron skids j2 and wooden pallets j3 are placed at the palletizing station j5. In this embodiment, 4 iron skids j2 are provided, and each iron skid j2 is numbered. An iron skid j2 with a certain number corresponds to loading a specific type of wooden pallet. When it is found that a wooden pallet is not placed on an iron skid j2 with a certain number, the staff immediately replenishes and places the corresponding type of wooden pallet j3 on the iron skid j2 with that number. That is, before palletizing, the corresponding type of wooden pallet j3 is manually placed on each numbered iron skid j2. The coil packaging control system can know the coil type to be palletized according to the upstream equipment located in the wooden pallet conveying device, and then know the iron skid j2 and wooden pallet to be transported to the palletizing station j5. It can be understood that since the wooden pallet j3 is manually placed on the iron skid j2, the wooden pallet j3 is not accurately positioned at this time, and it is impossible to determine whether the wooden pallet j3 is placed in the center, so there will generally be a placement error.

[0137] Regarding the placement position of the wooden pallet in the front-back direction, the following three situations will occur: First, set the length of the iron skid j2 as a mm. If the wooden pallet j3 is just placed in the center of the iron skid j2 without any placement error, the position of the front end face of the wooden pallet j3 is the standard position at this time, and the distance between the front end face of the wooden pallet j3 and the front edge of the iron skid j2 is s mm; the iron skid j2 carries the wooden pallet j3 and moves towards the palletizing station j5. When the iron skid travel detection device j42 senses the front end of the iron skid j2, the iron skid travel detection device j42 feeds back a signal to the coil packaging control system, records it as the first point, and the iron skid travel detection device j42 starts to monitor the moving stroke of the iron skid j2 in real time. As the iron skid j2 continues to move forward, the wooden pallet position detection device senses the front end face of the wooden pallet j3 and feeds back a signal to the coil packaging control system, records it as the second point, and the coil packaging control system immediately obtains the moving stroke △b1 of the iron skid j2 during the time from the first point to the second point.

[0138] (1) If △b1 = smm, it means that there is no placement error for the wooden pallet j3. After the palletizing conveyor line j1 drives the iron slide j2 to move forward by (a - △b1) mm, the wooden pallet j3 can accurately stop at the palletizing station j5. That is, when the iron slide travel detection device j42 monitors that the iron slide j2 has moved from the first point to the current travel △b2, and when △b2 = amm, a feedback signal is sent to the coil packaging control system, and the coil packaging control system controls the palletizing conveyor line 1 to stop moving.

[0139] (2) If △b1 < smm, it means that the wooden pallet j3 has shifted forward after being placed on the iron slide j2. At this time, the front end face of the wooden pallet j3 is located in front of the standard position. After the palletizing conveyor line j1 drives the iron slide j2 to move forward by [(a - s) - (s - △b1)] mm, the wooden pallet j3 can accurately stop at the palletizing station j5 to compensate for the placement error. That is, when the iron slide travel detection device j42 monitors that the iron slide j2 has moved from the first point to the current travel △b2, and when △b2 = (a - s + △b1) mm, a feedback signal is sent to the coil packaging control system, and the coil packaging control system controls the palletizing conveyor line j1 to stop moving.

[0140] (3) If △b1 > smm, it means that the wooden pallet j3 has shifted backward after being placed on the iron slide j2. At this time, the front end face of the wooden pallet j3 is located behind the standard position. After the palletizing conveyor line j1 drives the iron slide j2 to move forward by [(a - s) + (s - △b1)] mm, the wooden pallet j3 can accurately stop at the palletizing station j5 to compensate for the placement error. That is, when the iron slide travel detection device j42 monitors that the iron slide j2 has moved from the first point to the current travel △b2, and when △b2 = (a + s - △b1) mm, a feedback signal is sent to the coil packaging control system, and the coil packaging control system controls the palletizing conveyor line j1 to stop moving.

[0141] After the iron slide j2 transports the wooden pallet j3 to the palletizing station j5, the coil packaging control system controls the two pusher assemblies j43 to synchronously push the wooden pallet j3, so that the wooden pallet j3 is centered between the two pusher assemblies j43, correcting the deviation of the wooden pallet j3 in the left - right direction. The position of the wooden pallet j3 after positioning is the same as the preset placement setting. The auxiliary film roll flipping and handling device h accurately places the suspended packaging film roll on the wooden pallet j3. Then, the fixing part installation device k installs fixing parts on the top of the support clamping plate of the suspended packaging film roll, enabling the two suspended packaging film rolls to be stacked stably.

[0142] Specifically, the iron slide plate stroke detection device j42 includes a first bracket j421, a touch pressure detection head arranged above the first bracket j421, and an elastic push rod assembly j423 arranged on the top of the first bracket j421; the elastic push rod assembly j423 is used to push the touch pressure detection head to touch the iron slide plate j2. Under normal conditions, the elastic push rod assembly j423 provides elastic thrust for the touch pressure detection head, so that the touch pressure detection head extends and waits for the iron slide plate j2 to be triggered. When the front end of the iron slide plate j2 passes the touch pressure detection head, the front end of the iron slide plate j2 pushes the touch pressure detection head to retract, thereby triggering the touch pressure detection head. Under the action of the elastic push rod assembly j423, the touch pressure detection head always presses against the side of the iron slide plate j2 and monitors the moving stroke of the iron slide plate j2 in real time as the iron slide plate j2 moves.

[0143] Further, the touch pressure detection head includes a push wheel bracket j4221, a push wheel j4222, and a rotary encoder j4223 arranged above the push wheel j4222. The axis of the push wheel j4222 is arranged vertically and is rotatably connected to the push wheel bracket j4221 through a rotating shaft, and the rotary encoder j4223 is connected to the rotating shaft on the push wheel j4222. The push wheel j4222 is pressed against the side of the iron slide j2 by the elastic push rod assembly j423, and under the action of friction, the push wheel j4222 rotates with the movement of the iron slide j2. Since the rotating shaft rotates synchronously with the push wheel j4222, the rotary encoder j4223 can detect the angular displacement variable of the rotating shaft and the push wheel j4222, so that the coil packaging control system can calculate the rotation amount of the push wheel j4222 according to the circumference of the push wheel j4222, and the rotation amount of the push wheel j4222 is the travel distance of the iron slide j2.

[0144] Specifically, the elastic push rod assembly j423 includes a hollow sleeve j4231, a push rod j4232 passing through the inner cavity of the sleeve j4231, and a spring j4234 sleeved on the push rod j4232. The sleeve j4231 is provided with a stopper j4235 at one end facing the push wheel bracket j4221. One end of the push rod j4232 is fixedly connected to the push wheel bracket j4221, and the other end is provided with a limit head j4236 for limiting the push rod j4232 from being separated from the sleeve j4231. The spring j4234 is located between the stopper j4235 and the push wheel bracket j4221. Through such a configuration, the push wheel j4222 can, on the one hand, be compressed by the spring j4234 to buffer the moving impact of the iron slide j2, and on the other hand, the elastic force of the spring j4234 can ensure that the push wheel j4222 is always pressed against the side of the iron slide j2, thereby ensuring the effectiveness of the stroke detection of the iron slide j2.

[0145] Preferably, the wooden pallet position detection device includes a set of opposed sensors. The transmitter j411 and the receiver j412 of the opposed sensors are respectively arranged on the left and right sides of the palletizing station j5. The transmitter j411 emits infrared light to the receiver j412. When the infrared light is blocked by the wooden pallet j3, it indicates that the front end face of the wooden pallet j3 is detected by the opposed sensors.

[0146] The push plate assembly j43 includes a second bracket j431, a push plate carriage j432 slidably arranged on the second bracket j431, a push plate j433 fixed on the push plate carriage j432, and a push plate cylinder j434 for driving the push plate carriage j432 to reciprocate left and right. The push plate j433 extends transversely. The push plate cylinders j434 on the two push plate assemblies j43 move synchronously. The two push plate cylinders j434 drive the corresponding push plates j433 to move towards the center of the palletizing station j5. The two push plates j433 push against the side of the wooden pallet j3 to correct the deviation of the wooden pallet j3 in the left and right directions.

[0147] Specifically, the fixture installation device k includes a second three-axis drive structure k1 arranged on the frame y, a gripper assembly k8 arranged on the second three-axis drive structure k1, and a feeding mechanism k2 arranged beside the palletizing station. The gripper assembly k8 includes a gripper bracket k81, a picking and placing mechanism k82 arranged on the gripper bracket k81, a ranging mechanism k83, and a hammering mechanism k84. The picking and placing mechanism k82 is located on one side of the ranging mechanism k83. The hammering mechanism k84 is located above the picking and placing mechanism k82. The picking and placing mechanism k82 is used to grab the fixture on the feeding mechanism k82 and place the fixture on the support clamping plate. The ranging mechanism k82 is used to detect the distance between the installation gripper and the side of the support clamping plate. The hammering mechanism is used to hammer the fixture to make the fixture closely combine with the support clamping plate.

[0148] The fixture k9 is a workpiece for assisting palletizing. In the front projection from left to right, the fixture k9 is in an H shape. The fixture k9 includes a profile body in a "U" shape, and the profile body includes a bottom plate portion k91 and two vertical plate portions k92 respectively arranged on both sides of the bottom plate portion k91. The two vertical plate portions k92 and the bottom plate portion k91 enclose an upper notch. Each vertical plate portion k92 is provided with a turned-down flap k93. The two flaps k93 and the bottom plate portion k91 enclose a lower notch.

[0149] Since the control system has learned the specifications of the current film roll when the film roll is packaged, it can determine the specifications of the support clamping plates on the wooden pallet, thereby obtaining the preset height for placing the fasteners. The gripper assembly k8 makes flexible three-axis spatial movements under the coordinated movement of the second three-axis drive structure k1. The gripper assembly k8 first moves above the loading point of the feeding mechanism k2, and then the second three-axis drive structure drives the gripper assembly k8 to slowly descend. The gripper assembly k8 grabs the fastener k9, extends it into the upper slot of the fastener k9, and sucks the fastener k9. Then the gripper assembly k8 moves to the outside of the support clamping plate k14 and is at a suitable height for placing the fastener. Subsequently, the gripper assembly k8 moves in the direction close to the outer surface of the support clamping plate. When the gripper assembly k8 moves above the support clamping plate, the gripper assembly k8 stops moving. At this time, the fastener k9 is directly above the support clamping plate p2. Then the second three-axis drive structure k1 drives the gripper assembly k8 to slowly move downward, so that the lower slot of the fastener k9 is accurately stuck into the top of the support clamping plate, completing the automatic installation of one fastener k9. In fact, two fasteners k9 need to be installed front and back on each support clamping plate k14 to form four stable stacking fulcrums. Therefore, in order to improve the installation efficiency of the fasteners k9, in this embodiment, the second three-axis drive structure k1 and the gripper assembly k8 are provided with two groups and are symmetrically arranged. The installation work of the fastener k9 on one support clamping plate p2 corresponding to each gripper assembly k8 is carried out. The two gripper assemblies k8 synchronously carry out the feeding and installation work, each completing the installation of two fasteners k9, realizing the automatic assembly of the fasteners, solving the problems of low efficiency and high labor cost in manual assembly, and better promoting the automatic transformation of the coil suspension packaging production line.
