Description

Keel baling machine, keel baling system and keel baling method

[0001] This application claims priority to Chinese patent application No. 2024100647833, filed on January 16, 2024, entitled “Keel Packing Machine, Keel Packing System and Keel Packing Method”, the contents of which should be understood as incorporated into this application by reference. Technical Field

[0002] This article relates to but is not limited to the field of keel technology, and in particular to a keel packing machine, a keel packing system and a keel packing method. Background Art

[0003] The current way of packaging keels (such as cassette keels) on production lines is to stack multiple keels together and then use wire or tape to bundle them into small bundles.

[0004] Since the shapes of the two ends of the keel are different and the elasticity is different, the current bundling method results in inconsistent tightness at both ends after bundling, resulting in loose bundling. As a result, the bundled keel falls over when it is moved in the process before large-scale palletizing, resulting in more manual intervention during equipment failure, resulting in high production costs and low production efficiency. In addition, since the widths of the two ends after bundling are different, the overall space occupied after large-scale palletizing is large, affecting the factory's palletizing efficiency.

[0031] An embodiment of the present application provides a keel baling machine, as shown in Figures 1 to 11, the keel baling machine 100 includes a frame 1 and a stacking device 2 and a riveting device 5 installed on the frame 1; wherein, the stacking device 2 is configured to stack multiple keels 6 in sequence, and the riveting device 5 is configured to rivet the stacked multiple keels 6 together through rivets to form a whole bundle of keels.

[0032] The technical solution provided by the embodiment of the present application realizes the automatic stacking of keels by providing a stacking device 2. Then, the stacked keels are riveted together by a riveting device 5 using the openings provided on the keels (the openings are aligned after the multiple keels are stacked, and rivets can be inserted for riveting), thereby forming a whole bundle of keels. This keel bundling method not only realizes the automation of keel packaging, thereby improving production efficiency and reducing production costs, but also makes the bundled keels firm. In addition, since there is no wire or tape for binding on the keels, the keels are more neat when stacking the bundles, and the overall space occupied is small, which can improve the stacking efficiency and is not easy to fall over.

[0033] In one embodiment, the stacking device 2 is configured to stack the keels at a stacking station. The keel baling machine further includes a transfer device 3 configured to transfer the stacked keels 6 from the stacking station to a riveting station, where the riveting device 5 rivets the stacked keels 6. In this way, while the riveting station is riveting the stacked keels 6, keels 6 can continue to be stacked at the stacking station, thereby improving baling efficiency.

[0034] In one embodiment, the stacking device 2 includes a blanking mechanism 22 installed on the frame 1, and the blanking mechanism 22 is configured to blank multiple keels 6 in sequence to achieve stacking.

[0035] In the example shown in Figures 2 and 3, the blanking mechanism 22 includes a first blanking plate 221, a second blanking plate 222 and a blanking drive mechanism. The blanking drive mechanism is configured to drive the first blanking plate 221 and the second blanking plate 222 to rotate away from each other to open the blanking port, and to drive the first blanking plate 221 and the second blanking plate 222 to rotate toward each other to close the blanking port. When the first blanking plate 221 and the second blanking plate 222 open the blanking port, the keel 6 can fall from the blanking port.

[0036] In the example of Figure 3, the blanking drive mechanism includes a first rotating shaft 223, a second rotating shaft 224, a first gear 225, a second gear 226 and a gear driving member, the first rotating shaft 223 is connected to the first blanking plate 221, the second rotating shaft 224 is connected to the second blanking plate 222, and the first rotating shaft 223 and the second rotating shaft 224 are respectively rotatably mounted on the stacking frame 11 of the frame 1 through bearing seats 229; wherein, the gear driving member is configured to drive the first gear 225 to rotate, the first gear 225 and the second gear 226 are engaged, the first gear 225 drives the first rotating shaft 223 to rotate and the second gear 226 drives the second rotating shaft 224 to rotate, thereby driving the first blanking plate 221 and the second blanking plate 222 to rotate respectively to realize the opening and closing of the blanking port. The gear drive member may be a gear drive cylinder 227, and the first gear 225 may be a non-circular gear, or a non-circular structure having meshing teeth on one side. The driving end of the gear drive cylinder 227 may drive the first gear 225 to rotate back and forth, so that the second gear 226 rotates synchronously with the first gear 225. In this way, the first blanking plate 221 and the second blanking plate 226 may rotate synchronously to open the blanking port, so that the keel 6 will not deflect when blanking. The structure of the second gear 226 may be the same as or different from that of the first gear 225, as long as it can rotate back and forth through the meshing of the first gear 225.

[0037] In one embodiment, the stacking device 2 may further include a keel traction mechanism 21, which includes an upper roller 211 and a lower roller 212 rotatable on the frame 1, a roller rotation mechanism for driving one of the upper roller 211 and the lower roller 212 to rotate, and a roller lifting mechanism for driving the other to rise and fall. The roller lifting mechanism causes the upper roller 211 and the lower roller 212 to clamp the keel 6. The roller rotation mechanism drives one of the upper roller 211 and the lower roller 212 to rotate, thereby moving the keel 6 to the blanking mechanism 22. The blanking mechanism 22 may be provided with a plurality of guide rollers 228 spaced apart on both sides of the keel 6 and along the moving direction of the keel 6, so that the keel 6 moves in the correct direction.

[0038] In the example shown in FIG3 (combined with FIG7 ), the roller rotation mechanism is a roller drive motor 213 that drives the upper roller 211 to rotate, and the roller lifting mechanism is a roller lifting cylinder 214 that drives the lower roller 212 to rise and fall. When the roller lifting cylinder 214 rises, causing the lower roller 212 to rise to clamp the keel 6 together with the upper roller 211, the roller drive motor 213 drives the upper roller 211 to rotate, which can drive the keel 6 of a predetermined length to move to the blanking mechanism 22 and separate from the upper roller 211 and the lower roller 212. It is understandable that the roller drive motor 213 can also be connected to the lower roller 212, and the roller lifting cylinder 214 can be connected to the upper roller 211, and the upper roller 211 can be driven to descend to clamp the keel 6 with the lower roller 212.

[0039] During actual operation, a keel cutting device can be set upstream of the keel baling machine. When the keel traction mechanism 21 pulls the keel to a predetermined position, the keel cutting device can cut the keel, so that the keel 6 of a predetermined length is moved from the keel traction mechanism 21 to the blanking mechanism 22, and then the blanking mechanism 22 is controlled to make the keel 6 fall, and this is repeated to achieve the stacking of multiple keels 6.

[0040] In one embodiment, the stacking device 2 further includes an alignment mechanism configured to push the ends of the newly dropped keels 6 from the blanking mechanism 22 so that the ends of the stacked keels 6 are flush. In this way, the stacked keels are aligned in the length direction, and the rivet holes (the original openings on the keels) provided thereon are aligned, so that the keels can be neatly riveted together using rivets.

[0041] In the example shown in FIG3 , the pushing mechanism includes a pushing cylinder 23 disposed at the end of the blanking mechanism 22. The pushing cylinder 23 pushes each newly dropped keel 6, and the driving end of the pushing cylinder 23 pushes forward to a predetermined position so that the newly dropped keel 6 does not exceed the predetermined position. Specifically, the pushing frequency of the pushing cylinder 23 can be set according to the dropping frequency of the keels 6. In this way, when a predetermined number of keels (for example, ten) are dropped, the pushing cylinder 23 stops pushing. After the predetermined number of stacked keels 6 are moved to the riveting station, when the keels 6 are stacked again, the pushing cylinder 23 pushes the keels again at the predetermined frequency.

[0042] In one embodiment, as shown in Figures 2 and 4, the transfer device 3 includes a fork 35 and a fork driving mechanism for driving the fork 35 to move. When the fork 35 is in the stacking station, the stacking device 2 stacks multiple keels 6 on the fork 35. When the fork 35 is driven by the fork driving mechanism to move to the riveting station, the riveting device 5 rivets the keels 6 stacked on the fork 35.

[0043] In one example, the shift fork driving mechanism includes a shift fork driving motor 31 and a chain 34 driven by the shift fork driving motor 31 , and a plurality of shift forks 35 are arranged on the chain 34 at intervals along the length direction.

[0044] FIG2 shows a shift fork drive motor 31 connected to a reducer 32. The reducer 32 drives a transmission shaft 33 to rotate. The transmission shaft 33 extends along the length of the keel 6 dropped by the blanking mechanism 22. A chain mechanism having a chain 34 can be provided with multiple chains (two are shown in FIG2 , but more can be provided). The chains 34 are connected to the transmission shaft 33 at intervals along the length of the transmission shaft 33 to be driven by the transmission shaft 33. Each chain 34 is provided with multiple shift forks 35, and the positions of the shift forks 35 on the multiple chains 34 correspond to each other. That is, the multiple chains 34 are provided with shift forks 35 at the same multiple positions. In this way, the keel can be supported by multiple shift forks 35 arranged at intervals along the length.

[0045] 5 and 6 , the fork 35 includes a mounting bracket 353 mounted on the chain 34 and two oppositely arranged limit plates 351 connected to the mounting bracket 353 , and an accommodating space for accommodating the keel 6 is formed between the limit plates 351 , wherein in order to allow the keel 6 to easily enter between the two limit plates 351 , the tops of the two limit plates 351 are bent outward respectively, and a guide portion 352 is provided between the two limit plates 351 , and the guide portion 352 is provided to guide the first keel 6 to fall, so as to ensure that the keel 6 stacked at the bottom is in the correct position, and then the stacking position of the subsequently stacked keels can be ensured to be correct.

[0046] Figure 13 shows a cross-section of a keel 6 in an example. This cross-section is a U-shaped structure, and the spacing between the two layers of the U-shaped structure gradually increases along the direction toward the opening. When the opening of the keel 6 falls downward to the fork 35, the two side panels of the keel 6 move along the guide portion 352 to the bottom of the fork 35. The subsequent stacked keel 6 is then stacked on the keel below, guided by the layer of the keel below. Of course, in other embodiments, the keel 6 can also have other structural forms, such as a keel with a V-shaped cross-section, as long as it has a gradually expanding opening structure that allows stacking. In addition, it is understood that the keel 6 is not limited to being stacked with the opening facing downward; it can also be stacked with the opening facing upward.

[0047] In order to improve the packaging efficiency of the keel, the multiple forks 35 on each chain 34 are set as follows: when one of the forks 35 moves to the stacking station, the other fork 35 moves to the riveting station; when one of the forks 35 moves to the riveting station, the other fork 35 moves to the releasing station. At the releasing station, the fork 35 flips with the chain 34 to dump the keel.

[0048] Referring to the example shown in Figures 9 and 10 , in this example, a chain 34 is provided with five forks 35, namely a first fork 35a, a second fork 35b, a third fork 35c, a fourth fork 35d, and a fifth fork 35e, with equal spacing between the five forks. The figure shows that the first fork 35a is in the stacking position, capable of receiving the keels 6 dropped from the blanking mechanism 22. The second fork 35b is in the riveting position, where the riveting device 5 can rivet the multiple stacked keels carried by the second fork 35b. The third fork 35c is in the releasing position, located at the bend of the chain 34. The opening on the third fork 35c faces downward, enabling the dumping of the entire bundle of riveted keels. The dumped keels can then fall onto the conveyor 200. That is, the entire bundle of riveted keels is received and transported by the conveyor 200 after being dumped from the forks. After a predetermined number of keels are stacked on the first fork 35a and multiple keels on the second fork 35b are riveted and fixed, the chain 34 runs, the first fork 35a moves to the riveting station, the second fork 35b moves to the releasing station, and the fifth fork 35e moves to the stacking station. In this way, the chain runs in a cycle to complete the bundling operation of bundles of keels.

[0049] In one embodiment, the keel baling machine further includes a pressing device, which presses the stacked keels 6 before the stacked keels are riveted by the riveting device 5. The pressing device can press down the two ends of the stacked keels, or can apply pressure to the keels at certain intervals in the length direction, so that the thickness of the entire bundle of keels in the stacking direction is consistent, thereby ensuring that the volume of each bundle of keels is consistent, ensuring the neatness of the stacking, and avoiding the occurrence of tipping due to uneven stacking.

[0050] In the example shown in Figure 2, the pressing device includes a plurality of pressing cylinders 4, which are arranged at intervals along the length direction of the keel to press the stacked keels at multiple positions along the length direction of the keel. After the keel is pressed, the riveting operation is performed by the riveting device 5.

[0051] In one embodiment, as shown in Figures 4 and 5, the riveting device 5 includes a rivet feeding mechanism for feeding rivets into the riveting holes of the stacked multiple keels, and also includes a pushing mechanism 55 located below the stacked multiple keels and a pressing mechanism 54 located above the stacked multiple keels. The pushing mechanism 55 pushes against the rivet holes from below the keels, and the pressing mechanism 54 presses down the rivets in the rivet holes to achieve riveting.

[0052] In one example, the rivet feeding mechanism includes a vibrating feeder 51, a rivet clamp 52 and a transfer mechanism 53. The transfer mechanism 53 is configured to drive the rivet clamp 52 to move between a picking position and a discharge position. At the picking position, the rivet clamp 52 receives the rivet 7 given by the vibrating feeder 51 through vibration and clamps the rivet 7. At the discharge position, the rivet clamp 52 places the rivet 7 in the rivet hole of the keel.

[0053] Among them, the vibrating feeder 51 is an existing device that provides rivets by vibration and is not described in detail here. The rivet clamp 52 may include a clamping claw and a clamping mechanism. The clamping mechanism is configured to control the two clamping claws to clamp the rivet 7 when the sensor detects that the rivet 7 has fallen from the vibrating feeder 51 between the two clamping claws of the rivet clamp 52. The clamping mechanism that drives the clamping claws of the rivet clamp 52 to clamp may be a clamping cylinder. The transfer mechanism 53 includes a transfer cylinder 531 and a rotating frame 532 connected to the transfer cylinder 531. The rivet clamp 52 is installed on the rotating frame 532. The driving end of the transfer cylinder 531 is extended and retracted to control the rotating frame 532 to rotate back and forth between the two positions, thereby driving the rivet clamp 52 to rotate back and forth between the material collection position and the material discharge position. Figure 5 shows the rivet clamp 52 in two states. In one state, the rivet clamp 52 is in the picking position and can receive the rivets 7 dropped from the vibrating feeder 51 (a guide is provided between the rivet clamp 52 and the vibrating feeder 51, and the rivet 7 can fall directly between the two jaws of the rivet clamp 52 along the guide). In the other state, the rivet clamp 52 is in the discharging position and places the clamped rivets 7 into the rivet holes above the multiple stacked keels 6 at the riveting station.

[0054] In one example, the abutting mechanism 55 includes an abutting cylinder 551 and an abutting portion 552 connected to the driving end of the abutting cylinder 551. The abutting portion 552 can abut against the rivet holes below the stacked keels. The pressing mechanism 54 includes a pressing cylinder 541 and a pressing portion 542 connected to the driving end of the pressing cylinder 541. As shown in FIG5 , when the abutting portion 552 of the abutting mechanism 55 abuts against the rivet holes below the keels, the pressing portion 542 of the pressing mechanism 54 presses down the rivet 7 located in the rivet hole above the keel, thereby achieving riveting of multiple stacked keels with the rivet 7.

[0055] In addition, in one example, referring to Figures 7-11, the rack 1 includes a stacking rack 11, a riveting rack 12, and a material transfer rack 13. The stacking device 2 is mounted on the stacking rack 11, the riveting device 5 is mounted on the riveting rack 12, and the transfer device 3 is mounted on the transfer rack 13. The stacking rack 11 and the riveting rack 12 are arranged side by side along the width direction of the keel 6 to be bundled, and the transfer rack 13 is located in the space below the stacking rack 11 and the riveting rack 12. Of course, the structure of the rack 1 can have many variations, which are not limited here.

[0056] An embodiment of the present application also provides a keel packaging system, as shown in Figure 1, comprising the keel packaging machine 100 as described above, and also comprising a conveying device 200 and a palletizing device 300. The whole bundle of keels formed by riveting by the keel packaging machine 100 is moved to the conveying device 200, and the conveying device 200 is configured to transport the whole bundle of keels to the palletizing device 300, and the palletizing device 300 palletizes the whole bundle of keels.

[0057] The specific process of packing keels using a keel packing system is described in detail below based on an embodiment.

[0058] 2 , the keel 6 cut to a predetermined length is moved to the blanking mechanism 22 through the keel traction mechanism 21 ;

[0059] After receiving the keels 6, the blanking mechanism 22 controls the first blanking plate 221 and the second blanking plate 222 to open the blanking opening, and the keels 6 fall from the blanking opening to the shift fork 35 below. Each time a keel 6 falls, the aligning cylinder 23 pushes the keel 6 so that the ends of the stacked keels are flush.

[0060] After a predetermined number of keels are stacked, the transfer device 3 controls the chain 34 to operate, so that the fork 35 with the stacked keels 6 moves from the stacking station to the riveting station, and the other fork moves to the stacking station to continue receiving the stacked keels;

[0061] The multiple pressing cylinders 4 of the pressing device press the stacked keels at the riveting station;

[0062] Then, the riveting device 2 rivets the keel at the riveting station. Specifically, the vibrating feeder 51 vibrates and feeds, causing the rivet 7 to fall into the rivet fixture 52. After receiving the rivet 7 at the material taking position, the rivet fixture 52 moves to the material discharging position and places the rivet 7 in the riveting hole of the stacked keels. The abutting portion 552 of the abutting mechanism 55 moves upward to abut the riveting hole below the keel. The pressing portion 542 of the pressing mechanism 54 presses down the rivet 7 in the riveting hole from above, thereby achieving riveting of the keel.

[0063] The keel in this example is a U-shaped structure (see FIG13 ), with an opening provided at the bottom of the U-shaped structure. When multiple keels are stacked together, the openings at the bottoms of the multiple U-shaped structures align to form rivet holes that can be riveted. To facilitate riveting, the keels of the multiple stacked U-shaped structures are placed with their openings facing downward, so that the bottoms of the U-shaped structures face upward. The multiple pressing cylinders 4 press on the outside of the bottom of the U-shaped structure. The top portion 552 of the pressing mechanism 55 extends into the inside of the bottom of the U-shaped structure, while the pressing portion 542 of the pressing mechanism 54 is located above the outside of the bottom of the U-shaped structure to press down the rivet 7.

[0064] The control chain 34 moves, the shift fork 35 at the riveting station moves to the releasing station, while the shift fork 35 at the stacking station moves to the riveting station, and at the same time another shift fork moves to the stacking station;

[0065] The shift fork 35 of the releasing station dumps the whole bundle of keels to release the keels, and the released keels slide down along the sliding component 201 to the conveying device 200 (refer to FIG. 9 ), and the conveying device 200 conveys the keels to the palletizing device 300 .

[0066] As shown in Figure 12, the palletizing device 300 includes a palletizing frame 301 and a load-bearing frame 308. The palletizing frame 301 is equipped with a liftable lifting frame 302, a lifting cylinder 304 for driving the lifting frame 302 to lift and lower, and a transverse cylinder 303 for driving the lifting frame 302 to move transversely. The lifting frame 302 is provided with two or more keel clamping components 305, which are configured to clamp a whole bundle of keels. The clamping cylinder 306 is configured to control the two clamping parts of the keel clamping component 305 to clamp the keels. When the lifting cylinder 304 lowers the lifting frame 302 to the first position, the keel clamping components 305 clamp the entire bundle of keels on the conveyor 200. The lifting frame 302 then rises to the second position. The traverse cylinder 303 drives the lifting frame 302 to move laterally. When it reaches a predetermined position above the carrier 308, the unloading cylinder 307 pulls back the clamping portion of the keel clamping components 305 located below the keels, causing the keels to fall onto the carrier 308. The lifting frame 302 then moves back to the conveyor 200, clamping the keels delivered from the conveyor 200. This process is repeated until the keels are stacked on the carrier 308 in the desired layer height and width.

[0067] After a certain number of keels are stacked on the carrier 308, the drive motor of the feeding device 400 is started, and the rotating roller of the feeding device 400 and the rotating roller on the carrier 308 are driven by the chain to rotate. The keels stacked on the carrier 308 are moved to the feeding device 400 as the rotating roller rotates. Then the feeding device 400 can deliver the keels to the forklift unloading area, and the entire work process is completed.

[0068] An embodiment of the present application further provides a keel packaging method, the method comprising:

[0069] Stack multiple keels;
