DETAILED DESCRIPTION

[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 replenishing machine suitable for pillow packaging line, comprising a base platform 1 and a cover outside the base platform 1, the base platform 1 table is provided with a conveying belt 8, the base platform 1 is provided with a first workbench 2 higher than the conveying belt 8 on one side of the conveying belt 8 and a second workbench 3 not lower than the conveying belt 8 on the other side, and the base platform 1 is provided with a feeding mechanism at the bottom side of the first workbench 2; the feeding mechanism comprises a rotary drive 10 and at least two feeding bins 9 on the rotary drive 10, one of which is matched with the conveying line and the other is matched with the conveying belt 8; the first workbench 2 is sequentially provided with a first overall bag scraping mechanism 4 and a second overall bag scraping mechanism 5 along the conveying direction of the conveying belt 8; the second workbench 3 is provided with an opening corresponding to one side of the conveying belt 8, and the opening is provided with a bag replenishing mechanism 19, the bag replenishing mechanism 19 comprises a bag replenishing bin 20 and a discharge channel 22, the bag replenishing bin 20 is matched with the conveying belt 8 and arranged on the opposite side of the second overall bag scraping mechanism 5, the discharge channel 22 is fixedly arranged at the bottom end of the bag replenishing bin 20, the bottom of the discharge channel 22 is provided with a linear module 14 parallel to the conveying belt 8, the second workbench 3 is provided with a single-channel bag scraping mechanism 6 at the bag replenishing mechanism 19, and the second workbench 3 is provided with a third overall bag scraping mechanism 7 at the tail of the conveying belt 8; the bag replenishing 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 replenishing bin 20 respectively, and the single-channel cylinder 17 is connected with a single-channel scraper 18.

[0036] 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 first 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 conveying line pushes the strip package to the feeding bin 9 and the first integral bag scraping mechanism 4 pushes the strip package 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 package is pushed to the end of the corresponding feeding bin 9, the two transition bins 11 are lifted to be higher than the feeding bin 9, and in the state that the rotary drive 10 starts to rotate and stops rotating, the strip package in the feeding bin 9 is protected from being thrown out. 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 package 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 package during the entire rotation of the rotary drive 10.

[0037] The two sides of the bag replenishment bin 20 and the open side wall 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 second workbench 3 without interference, and other components located at the bottom side of the second workbench 3 are also protected.

[0038] The bag replenishment bin 20 is provided with a swing cylinder 23 connected with a turnover plate 24 at each bin. Each bin is provided with a turnover plate 24 and a swing cylinder 23, so that the bag replenishment mechanism 19 has the functions of single-channel replenishment and single-channel rejection.

[0039] The swing cylinder 23 is provided with a rotation gap that can rotate the rotating shaft of the turnover plate 24 by 90°, and the turnover plate 24 is provided with a limiting block 25 that can abut 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.

[0040] The first, second and third integral bag scraping mechanisms 4, 5 and 7 each comprise a linear module 14 and a scraping cylinder 15 connected to the extension end of the linear module 14, the piston rod of the scraping cylinder 15 extends downward and is provided with an integral scraper 16 wider than the integral strip bag to be scraped.

[0041] The first workbench 3 is provided with a notch at the material inlet bin 9 matched with the conveying belt 8, and the first integral bag scraping mechanism 4 is arranged at the notch on the top surface of the first workbench 3. The notch is arranged on the first workbench 3 in the pushing direction of the first integral bag scraping mechanism 4, so as to avoid interference of the first workbench 3 with the first integral bag scraping mechanism 4 when the first integral bag scraping mechanism 4 pushes the material. When the first integral bag scraping mechanism 4 is fixedly arranged at the bottom end of the first workbench 3, the notch can not be arranged on the first workbench 3.

[0042] In the embodiment, one column of strip bags is 10, and the specific bag supplementing method steps are as follows:

[0043] (1) Before the operation of the bag supplementing machine, the transition material bins 11 and the two material inlet bins 9 are all in the initial position, one of the material inlet bins 9 corresponds to the conveying belt 8, and the other material inlet bin 9 corresponds to the conveying line for conveying the integral strip bags, the conveying line continuously conveys the integral strip bags to the corresponding material inlet bin 9 of the feeding mechanism, at this time, the two transition material bins 11 are both 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 inlet bin 9. After the conveying line conveys the first group of integral strip bags to the material inlet bin 9, the piston rods of the two lifting cylinders 12 extend to make the transition material bins 11 higher than the material inlet bin 9, the rotary drive 10 rotates the material inlet bin 9 containing the strip bags to correspond to the conveying belt 8, the piston rods of the two lifting cylinders 12 retract to make the transition material bins 11 flush with the material inlet bin 9, the first integral bag scraping mechanism 4 is started to push the integral strip bags to the conveying belt 8, the first integral bag scraping mechanism 4 retracts, and then the conveying belt 8 is driven by the motor to move forward to the position where the first group of integral strip bags is aligned with the bag supplementing bin 20, at the same time, the rotary drive 10 rotates to rotate the next material inlet bin 9 containing the integral strip bags to the conveying belt 8, and the operation is repeatedly repeated. In the embodiment, the motor of the conveying belt 8 is fixedly arranged at the bottom end of the second workbench 3.

[0044] (2) When initially operated, the conveying belt 8 conveys the first group of integral strip bags to the position corresponding to the bag supplementing bin 20, if the first group of strip bags is complete, the conveying belt 8 directly conveys the first group of strip bags backward, if the first group of strip bags has a vacancy, the second integral bag scraping mechanism 5 is started to push the first group of strip bags into the bag supplementing bin 20, and then the second group of integral strip bags is conveyed to the position to be supplemented.

[0045] (3) When a gap appears in the second group of strips and the replenishment hopper 20 has strips that can be replenished completely at once, the linear module 14 at the bottom of the replenishment mechanism 19 is controlled to move laterally, aligning the replenishable strip with the station to be replenished. The corresponding single-channel cylinder 17 on the single-channel scraping mechanism 6 is activated to lower the single-channel scraper 18. The linear module 14 pushes the single-channel scraper 18 to replenish the strips in the replenishment hopper 20 to the station to be replenished on the conveyor belt 8, making the strips in that row complete. Figure 10 As 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.

[0046] (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.

[0047] like Figure 12As shown, when the above-mentioned case does not have a strip bag in the 9th and 10th positions of the bag-replenishing position, the bag-replenishing position 20 is not reset, the 8th position strip bag which is repeated with the bag-replenishing position is directly rejected, and then the strip bag of the bag-replenishing position is pushed into the bag-replenishing position 20 as a new bag-replenishing strip bag.

[0048] (5) Repeat the above steps to perform the bag-replenishing operation.

[0049] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
