DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Such as Figures 1 to 4As shown in the figure, the utility model relates to a high-speed back-sealing in-line bag replenishing device, which includes a feeding conveyor belt 1 driven by a servo motor, used to receive back-sealed bags that are intermittently pushed after being weighed and inspected by a small bag sorting machine to eliminate unqualified products; on one side of the output end of the feeding conveyor belt 1, there is a counting conveyor belt 2 driven by a servo motor, and on the other side, there is a transition pusher 21, used to push a group of back-sealed bags on the feeding conveyor belt 1 onto the counting conveyor belt 2; the counting conveyor belt 2 is arranged parallel and at the same height as the feeding conveyor belt 1.

[0028] Rectangular grooves are evenly distributed on the feeding conveyor belt 1 and the counting conveyor belt 2 respectively, so as to facilitate the placement and transportation of back-sealed bags. The transition pusher 21 includes a push plate 3, a pusher cylinder 5 and two guiding components 4. The piston rod of the pusher cylinder 5 is connected to the middle of one side of the push plate 3. The two guiding components 4 are symmetrically arranged on both sides of the pusher cylinder 5, and the guiding rods are respectively connected to the push plate 3. The cylinder body of the pusher cylinder 5 and the guiding seats of the two guiding components 4 are respectively fixed on the other side of the output end of the feeding conveyor belt 1 through a transition pusher bracket 6.

[0029] On one side of the middle of the counting conveyor belt 2, there is a detection component, used to detect whether there are back-sealed bags in the grooves on the counting conveyor belt 2 entering the detection area. The detection component includes a detection bracket 18 fixed on one side of the middle of the counting conveyor belt 2. A number of detection sensors 17 are evenly fixed on the detection bracket 18. The detection sensors 17 correspond one by one to the grooves on the counting conveyor belt 2 entering the detection area, so as to facilitate detection. The detection sensor 17 is preferably a photoelectric sensor. The signal output end of the photoelectric sensor is connected to the PLC controller (not shown in the figure) of the high-speed back-sealing in-line bag replenishing device. The controller is used to control the servo motors of each conveyor belt and the actions of each cylinder.

[0030] On the other side of the counting conveyor belt 2, there is a bag replenishing conveyor belt 7 driven by a servo motor in parallel, used to store back-sealed bags required for bag replenishment; on the side of the middle of the bag replenishing conveyor belt 7 far from the counting conveyor belt 2, there is a bag replenishing pusher 22, used to replenish the missing bag grooves on the counting conveyor belt 2 after entering the bag replenishing area. Grooves are evenly distributed on the bag replenishing conveyor belt 7 and correspond one by one to the grooves on the counting conveyor belt 2, so as to facilitate bag replenishment.

[0031] The bag replenishing pusher 22 includes a slide plate 8 arranged horizontally. A number of vertically arranged sliding grooves are evenly distributed on the slide plate 8 in the horizontal direction, and a bag replenishing push plate 26 is slidably installed in each sliding groove respectively; on the slide plate 8 at the opening side of the sliding groove, a cylinder bracket 9 is fixedly attached, used to limit the bag replenishing push plate 26 in the sliding groove; the cylinder bracket 9 is formed by stamping a plate and is approximately S-shaped. A number of selection cylinders 10 are evenly arranged at the upper end of the cylinder bracket 9. The selection cylinders 10 correspond one by one to the bag replenishing push plates 26 and are connected to each other, used to push the corresponding bag replenishing push plates 26 to move up and down along the sliding grooves;

[0032] On one side of the cylinder bracket 9, a bag mending cylinder 11 and two symmetrically arranged guiding components 12 are connected. The cylinder body of the bag mending cylinder 11 and the guiding seat of the guiding component 12 are fixed on one side of the bag mending conveyor belt 7 through a bag mending bracket 25. The cylinder body of the bag mending cylinder 11 and the guiding rod of the guiding component 12 are respectively fixedly connected to the cylinder bracket 9.

[0033] On the side of the counting conveyor belt 2 away from the bag mending pusher 22, a bag taking pusher 16 is provided. The bag taking pusher is located in front of the detection component and is opposite to the position of the bag mending pusher 22, and is used to push the back-sealed bags entering the bag mending area on the counting conveyor belt 2 onto the bag mending conveyor belt to prepare for storing bags for the next cycle of bag mending work. The bag taking pusher has the same structure as the transition pusher 21 and is fixed on the side plate on one side of the counting conveyor belt 2 through a bag taking pusher bracket 24.

[0034] On the side of the output end of the counting conveyor belt 2 and on the side of the bag mending conveyor belt 7, a counting pusher 23 is provided, which is used to push the back-sealed bags entering the lane counting area on the counting conveyor belt 2 onto the lane counting board.

[0035] The counting pusher 23 includes a push plate 15 and two counting pusher cylinders 14. The two counting pusher cylinders 14 are symmetrically connected to both ends on one side of the push plate 15, and the two counting pusher cylinders 14 are fixed on the side plate on one side of the counting conveyor belt 2 and the bag mending conveyor belt 7 through a counting pusher bracket 13.

[0036] The lane counting board 19 is arranged on the side of the output end of the counting conveyor belt 2 and on the side of the bag taking pusher 16, and is used to gradually push the pushed group of back-sealed bags onto the lane counting and packaging chain 20 through a reciprocating push plate (not shown in the figure) provided thereon. During the pushing process, the group of back-sealed bags is divided into several equally spaced groups of back-sealed bags that meet the subsequent packaging requirements, and finally is pushed onto the lane counting and packaging chain 20.

[0037] During operation, the specific working process is as follows:

[0038] 1. After the back-sealed bags produced by the multi-column back-sealing equipment are sorted by the sorting machine to remove unqualified products, they are pushed into the grooves on the incoming material conveyor belt 1; the incoming material conveyor belt 1 is driven intermittently by a servo motor to convey the back-sealed bags to the transition area at the output end. In the transition area, the pusher cylinder 5 of the transition pusher 21 is started to push the back-sealed bags on the incoming material conveyor belt 1 onto the counting conveyor belt 2 to complete the transition between the conveyor belts.

[0039] 2. The back-sealed bags entering the counting conveyor belt 2 are intermittently conveyed by the counting conveyor belt 2 and sequentially pass through the detection area of the missing bag detection, the bag mending area of the bag mending station, and the lane counting area corresponding to the lane counting board.

[0040] 3. In the detection area, the detection sensors 17 evenly and fixedly arranged on the detection bracket 18 detect the presence or absence of the back-sealed bags on the counting conveyor belt 2, and transmit the detection results to the controller, facilitating the operation of the bag-filling pusher 22 in the next step when entering the bag-filling area to complete the grooves of the missing back-sealed bags.

[0041] 4. In the bag-filling area, according to the previous bag-missing detection results and the positions of the back-sealed bags on the bag-filling conveyor belt 7, the controller controls the corresponding selection cylinder 10 to work, pushing the corresponding bag-filling push plate 26 downward; then controls the bag-filling cylinder 11 to extend, pushing the slide plate and the bag-filling push plate 26 to move horizontally forward, and pushing the back-sealed bags in the corresponding grooves on the bag-filling conveyor belt 7 to the counting conveyor belt 2 entering the bag-filling area through the bag-filling push plate 26 to complete the bag-filling work;

[0042] At the same time, the controller adjusts the position of the back-sealed bags in the corresponding bag-filling area on the bag-filling conveyor belt, and drives the bag-filling conveyor belt to operate to adjust the positions of the back-sealed bags according to the actual bag-missing and filling positions, preparing for the subsequent bag-filling work.

[0043] 5. When the controller determines based on the detection results of the detection sensors 17 that the back-sealed bags stored on the bag-filling conveyor belt 7 cannot meet the bag-filling work requirements for the counting conveyor belt 2 in the bag-filling area, it controls the bag-filling conveyor belt 7 to start, moving the remaining back-sealed bags on the bag-filling conveyor belt 7 out of the bag-filling area. Then it controls the pusher cylinder of the bag-taking pusher to work, pushing the back-sealed bags on the counting conveyor belt 2 in the bag-filling area to the bag-filling conveyor belt 7 to complete the bag storage work of the bag-filling conveyor belt 7. The remaining back-sealed bags on the bag-filling conveyor belt 7 fall into the receiving trough from one end for recycling.

[0044] 6. When a group of back-sealed bags after bag-filling on the counting conveyor belt 2 are sent to the lane counting area of the corresponding lane counting board, the controller controls the counting pusher cylinder 14 of the counting pusher 23 to start, driving the push plate of the counting pusher to push the back-sealed bags from the counting conveyor belt 2 to the lane counting board. The lane counting board divides the back-sealed bags into several equal groups meeting the subsequent packaging requirements as required, and finally they are pushed onto the lane counting and packaging chain at the output end of the lane counting board to complete the feeding work for the subsequent packaging.
