[0034] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0035] As Figures 1 to 9As shown, a high-efficiency bag supplementing method suitable for pillow packaging line, comprising a base platform 1 and a cover outside the base platform 1, one side of the base platform 1 is provided with a feeding device capable of pushing two materials, the base platform 1 is provided with a linear running conveying belt 8 corresponding to the feeding device, the other side of the conveying belt 8 is provided with a supplementing workbench 3 not lower than the conveying belt 8; the supplementing workbench 3 is provided with an opening corresponding to one side of the conveying belt 8, the opening is provided with a bag supplementing mechanism 19, the bag supplementing mechanism 19 comprises a bag supplementing bin 20 and a discharging channel 22, the bag supplementing bin 20 is matched with the conveying belt 8, the discharging channel 22 is fixedly arranged at the bottom end of the bag supplementing bin 20, the bottom of the discharging channel 22 is provided with a linear module 14 parallel to the conveying belt 8, the supplementing workbench 3 is provided with a single-channel bag scraping mechanism 6 at the bag supplementing mechanism 19, and the supplementing workbench 3 is provided with an overall bag scraping mechanism at the tail of the conveying belt 8; the bag supplementing bin 20 is provided with a turnover plate 24 capable of closing the bin by rotating at the bottom end of each bin; the single-channel bag scraping mechanism 6 comprises a linear module 14 and a single-channel cylinder 17 arranged in the same row on the linear module 14, the single-channel cylinder 17 is matched with each bin of the bag supplementing bin 20 respectively, and a single-channel scraper 18 is connected to the single-channel cylinder 17; the bag supplementing method comprises the following steps:

[0036] (1) The conveying line continuously conveys the whole column of strip packages to the feeding device, the feeding device pushes the first whole column of strip packages to the conveying belt 8, then the conveying belt 8 runs forward to align the first whole column of strip packages with the bag supplementing bin 20, at the same time, the feeding device pushes the subsequent whole column of strip packages to the conveying belt 8, and the operation is repeated repeatedly;

[0037] (2) When initially running, the conveying belt 8 conveys the whole column of strip packages to the supplementing position corresponding to the bag supplementing bin 20, if the column of strip packages is complete, it is directly conveyed backward by the conveying belt 8, if the column of strip packages has a vacancy, the feeding device pushes the column of strip packages into the bag supplementing bin 20, and then the next batch of whole column of strip packages is conveyed to the supplementing position;

[0038] (3) When the next batch of strip packages has a vacancy and the bag supplementing bin 20 has a complete column of strip packages which can be supplemented at one time, the linear module 14 at the bottom of the bag supplementing mechanism 19 is controlled to horizontally translate, the supplementable strip packages are aligned with the supplementing position, the single-channel cylinder 17 of the single-channel bag scraping mechanism 6 is started to lower the single-channel scraper 18, the linear module 14 pushes the single-channel scraper 18 to supplement the strip packages in the bag supplementing bin 20 to the supplementing position on the conveying belt 8, so that the column of strip packages is complete, when the bag supplementing bin 20 has multiple complete columns of strip packages which can be supplemented at one time, one side of the bag supplementing bin 20 is selected as the initial supplementing direction, the strip packages corresponding to the side are preferentially supplemented, the complete whole column of strip packages is continuously conveyed backward by the conveying belt 8, and the complete whole column of strip packages is pushed out of the conveying belt 8 by the overall bag scraping mechanism at the tail of the conveying belt 8 for packaging.

[0039] (4) When there is a vacancy in the strip package at the position to be replenished, but the remaining strip packages in the bag replenishment bin 20 do not have a complete strip package that can be replenished at one time, the bag replenishment bin 20 is reset, the swing cylinder 23 in the bag replenishment bin 20 corresponding to the repeated strip package position of the strip package at the position to be replenished is opened, the bottom of the corresponding bin is opened by rotating the turnover plate 24, and the repeated strip package in the bag replenishment bin 20 falls out of the discharge channel 22. Then the feeding device is started to push the strip package at the position to be replenished into the bag replenishment bin 20 as a new bag replenishment strip package. When there is no strip package in the position of the bag replenishment bin 20 corresponding to the position to be replenished, the bag replenishment bin 20 is not reset, and the repeated strip package corresponding to the position to be replenished is directly rejected, and then the strip package at the position to be replenished is pushed into the bag replenishment bin 20 as a new bag replenishment strip package.

[0040] (5) Repeat the above steps to replenish the bag.

[0041] The feeding device includes a pushing workbench 2, a rotary drive 10, and a feeding bin 9. The pushing workbench 2 is higher than the conveying belt 8, and two whole bag scraping machines are sequentially arranged on the pushing workbench 2 along the conveying direction of the conveying belt 8. The rotary drive 10 is fixedly arranged on the base platform 1 and located at the bottom side of the pushing workbench 2. The feeding bin 9 is arranged on the rotary drive 10 and has at least two feeding bins, one of which is matched with the conveying line, and the other of which is matched with the conveying belt 8. The pushing workbench 2 is provided with a notch at the feeding bin 9 matched with the conveying belt 8, and one of the whole bag scraping machines is arranged on the top surface of the pushing workbench 2 corresponding to the notch. The feeding bin 9 is used to transfer the whole row of strip packages from the conveying line to the conveying belt 8. The first whole bag scraping machine 4 on the pushing workbench 2 is used to push the whole row of strip packages onto the conveying belt 8, and the second whole bag scraping machine 5 is used to push the whole row of strip packages onto the bag replenishment bin 20. As shown in FIG. 4, the pushing workbench 2 is provided with a notch at the feeding bin 9 matched with the conveying belt 8, which can avoid interference when the first whole bag scraping machine 4 pushes the material. When the first whole bag scraping machine 4 is fixedly arranged at the bottom end of the pushing workbench 2, the notch can not be opened on the pushing workbench 2. Figure 1

[0042] The whole bag scraping machine includes a linear module 14 and a scraping cylinder 15. The scraping cylinder 15 is connected to the extension end of the linear module 14, and the piston rod of the scraping cylinder 15 extends downward and is provided with a whole scraping plate 16 wider than the whole row of strip packages to be scraped. The scraping cylinder 15 is used to extend downward to lower the whole scraping plate 16, and the whole scraping plate 16 is pushed by the linear module 14 after reaching the position.

[0043] ​The top surface of the rotary drive 10 is fixedly provided with a circular turntable, the edges of each feeding bin 9 match the outer periphery of the circular turntable, transition bins 11 are arranged between the feeding bin 9 and the conveying line and between the feeding bin 9 and the conveying belt 8, the bottom of each transition bin 11 is provided with a lifting cylinder 12, the pushing workbench 2 has a gap for arranging the transition bin 11, and the lifting cylinders 12 are fixedly provided with an arc-shaped baffle 13 surrounding the periphery of the circular turntable. When the two transition bins 11 push the strip packs to the feeding bin 9 and the first integral bag scraping mechanism 4 pushes the strip packs to the conveying belt 8, the lifting cylinders 12 are in a retracted state, and the two transition bins 11 are in a lowered position and are flush with the corresponding feeding bin 9. When the strip packs are pushed, the two transition bins 11 are raised to be higher than the feeding bin 9 and are arranged at the end of the corresponding feeding bin 9, so that the strip packs in the feeding bin 9 are protected from being thrown out in the state that the rotary drive 10 starts to rotate and stops rotating. The feeding bin 9 is provided with four feeding bins 9, which are uniformly arranged on the circular turntable. The uniform arrangement of the four feeding bins 9 can enable the rotary drive 10 to replace the feeding bin 9 of the conveying belt 8 once every 90°, so that the continuous bag replenishment is completed in a directional and quantitative manner. The arc-shaped baffle 13 between the lifting cylinders 12 can also prevent the strip packs from being thrown out due to centrifugal force during the rotation of the rotary drive 10, and cooperates with the transition bin 11 to protect the strip packs during the whole rotation of the rotary drive 10.

[0044] The two sides of the bag replenishment bin 20 and the side wall of the second opening are provided with an organ protection cover 21, which can be elongated and compressed, so that the bag replenishment bin 20 can be laterally translated in the opening of the bag replenishment workbench 3 without interference, and other components located at the bottom side of the bag replenishment workbench 3 are also protected.

[0045] The bag replenishment bin 20 is provided with a swing cylinder 23 connected with a turnover plate 24 at each bin. One turnover plate 24 and one swing cylinder 23 are arranged at each bin, so that the bag replenishment mechanism 19 has the functions of single-channel replenishment and single-channel rejection.

[0046] The swing cylinder 23 is provided with a rotation gap capable of rotating the rotating shaft of the turnover plate 24 by 90°, and the turnover plate 24 is provided with a limiting block 25 capable of abutting against the rotation gap. The cooperation of the 90° rotation gap and the limiting block 25 can limit the rotation range of the turnover plate 24, so as to avoid interference with adjacent bins due to too large rotation range of the turnover plate 24.

[0047] In this embodiment, a row of strip packs is 10, and the specific bag replenishment method steps are as follows:

[0048] (1) Before the operation of the bag replenishing machine, the transition material bin 11 and the two material feeding bins 9 are in the initial position, one of the material feeding bins 9 corresponds to the conveying belt 8, and the other material feeding bin 9 corresponds to the conveying line for conveying the whole row of bags, the conveying line continuously conveys the whole row of bags to the corresponding material feeding bin 9 of the feeding mechanism, at this time, the two transition material bins 11 are in the lowered position, and the piston rods of the two lifting cylinders 12 are in the retracted state, that is, the two transition material bins 11 are flush with the corresponding material feeding bin 9. After the conveying line conveys the first group of whole row of bags to the material feeding bin 9, the piston rods of the two lifting cylinders 12 are extended to make the transition material bins 11 higher than the material feeding bin 9, the rotary drive 10 rotates the material feeding bin 9 containing the bags to correspond to the conveying belt 8, the piston rods of the two lifting cylinders 12 are retracted to make the transition material bins 11 flush with the material feeding bin 9, the first whole row of bag scraping mechanism 4 is started to push the whole row of bags to the conveying belt 8, the first whole row of bag scraping mechanism 4 is retracted, and then the conveying belt 8 is driven by the motor to run forward to the first group of whole row of bags aligning with the bag replenishing bin 20, at the same time, the rotary drive 10 rotates to rotate the next material feeding bin 9 containing the whole row of bags to the conveying belt 8, and the operation is repeated. In the embodiment, the motor of the conveying belt 8 is fixedly arranged at the bottom end of the material replenishing workbench 3.

[0049] (2) When initially operated, the conveying belt 8 conveys the first group of whole row of bags to the bag replenishing position corresponding to the bag replenishing bin 20, if the first group of bags is complete, the conveying belt 8 directly conveys the bags backward, if the first group of bags has a vacancy, the second whole row of bag scraping mechanism 5 is started to push the first group of bags into the bag replenishing bin 20, and then the second group of whole row of bags is conveyed to the bag replenishing position.

[0050] (3) When the second group of bags has a vacancy and the bag replenishing bin 20 has a whole row of bags that can be replenished at one time, the linear module 14 at the bottom of the bag replenishing mechanism 19 is controlled to horizontally translate to align the replenishable bags with the bag replenishing position, the single-cylinder 17 corresponding to the single-cylinder 17 is started to lower the single-cylinder 18, the single-cylinder 18 is pushed by the linear module 14 to replenish the bags in the bag replenishing bin 20 to the bag replenishing position on the conveying belt 8, so that the row of bags is complete. Figure 10As shown, when the replenishment hopper 20 has multiple sets of strips that can be replenished completely at once, for example, if strips at positions 6 and 8 are missing in the second set of strips, and the two strips are in a state of being separated by a single position, the strips in the replenishment hopper 20 that are in a state of being separated by a single position are: positions 2 and 4, positions 4 and 6, and positions 7 and 9. Then, one side of the replenishment hopper 20 is selected as the initial replenishment direction, and the strips corresponding to that side are preferentially selected for replenishment. In this embodiment, the side of position 1 is selected as the initial replenishment direction. Then, the straight module 14 at the bottom of the replenishment mechanism 19 is controlled to move laterally, so that the strips at positions 2 and 4 of the replenishment hopper 20 are aligned with the strips at positions 6 and 8 in the second set of strips. Then, they are replenished by the single-stage scraping mechanism 6. The replenished strips continue to be conveyed backward by the conveyor belt 8, and the complete strips are pushed out by the conveyor belt 8 for packaging by the third overall scraping mechanism 7.

[0051] (4) When a gap appears in the strip package at the station to be replenished, but the remaining strip packages in the replenishment hopper 20 do not have enough strip packages to replenish completely at once, the replenishment hopper 20 resets, the swing cylinder 23 in the replenishment hopper 20 that has a duplicate strip package position with the strip package at the station to be replenished is activated, the flip plate 24 is rotated to open the bottom of the corresponding hopper, so that the duplicate strip packages in the replenishment hopper 20 fall out through the discharge channel 22. Figure 11 As shown, for example, if the strips at the station to be replenished are missing strips in positions 2, 4, and 5, and the replenishment hopper 20 has strips in positions 4, 6, and 8, even if the replenishment hopper 20 is laterally shifted to align positions 4 and 6 with positions 2 and 4 at the station to be replenished, it is still impossible to replenish all the strips at the station to be replenished at once. Simultaneously, the strip in position 8 at the replenishment hopper 20 will overlap with the strip in position 6 at the station to be replenished. If the strips are duplicated, preventing the entire strip to be replaced from being pushed into the replacement bag hopper 20 as a new replacement strip, the replacement bag hopper 20 will reset. The swing cylinders 23 at positions 6 and 8 in the replacement bag hopper 20 will be activated to rotate the flip plate 24, causing the strips at positions 6 and 8 to fall out through the discharge channel 22. Then, the second overall bag scraping mechanism 5 will be activated to push the strips at the replacement station into the replacement bag hopper 20 as new replacement strips.

[0052] like Figure 12 As shown, when the work station to be repaired is misplaced and there are no strip packages in positions 9 and 10 of the bag repair hopper 20, the bag repair hopper 20 is not reset. Instead, the strip package in position 8, which is the same as the work station to be repaired, is directly removed. Then, the strip package in the work station to be repaired is pushed into the bag repair hopper 20 as a new strip package for bag repair.

[0053] (5) Repeat the above steps to replenish the bags.

[0054] The above merely provides the preferred embodiment of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
