Description

Technical Field

[0001] This invention relates to a material conveying device, specifically to a feeding mechanism for strip packages before boxing. Background Technology

[0002] Feeding of flat, strip-shaped packages (referred to as strip packs) before boxing is crucial. If the feeding is incomplete, the number of strip packs to be boxed will be incorrect, resulting in substandard packaging, low packaging yield, increased production consumption, and increased production costs. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a bar bag reversing feeding mechanism that integrates bar bag feeding reversal, replenishment, and automatic return after replenishment, ensuring no material shortage during bar bag feeding and featuring a simple operating structure.

[0004] This invention is implemented through the following technical solutions: A reversing feeding mechanism for strip packages includes a reversing feeding disc that rotates at indexing intervals during operation. The reversing feeding disc is characterized by having a feeding station, a replenishing station, and a discharging station arranged circumferentially. Each station has a receiving plate fixedly installed on the reversing feeding disc. Each receiving plate has M receiving slots arranged horizontally. The feeding station faces the outlet of the strip package pushing platform. The strip package pushing platform has M strip-shaped material channels arranged horizontally. Each strip-shaped material channel of the strip package pushing platform is equipped with a sensor to detect whether a strip package is present in that channel. Two replenishing stations are provided, and a replenishing material is installed on the outer side of the receiving plate at each replenishing station. The feeding plate is mounted on a horizontal slide, which is controlled by a feeding servo motor to move laterally. M feeding slots are arranged on the left and right sides of the feeding plate, corresponding to the receiving slots on the receiving plate. Above the feeding plate is a feeding pusher plate that pushes the strip packages on the feeding plate to the receiving plate at the feeding station. The feeding pusher plate can move back and forth on the feeding pusher plate seat, which is controlled by a pusher plate seat servo motor to move laterally. Above the feeding station is also a return pusher plate that pushes the strip packages on the receiving plate at the feeding station to the feeding plate. The sensor, feeding servo motor, pusher plate seat servo motor are electrically connected to the PLC.

[0005] The discharge station faces the strip bag conveyor belt, which is driven by a conveyor belt servo motor to make intermittent circular motion. The conveyor belt servo motor is electrically connected to the PLC. Strip grooves are set at equal intervals on the strip bag conveyor belt, and the spacing between the strip grooves is equal to the spacing between the receiving grooves. M strip grooves form a set of conveying units, which are set on chain link seats and connected to the strip bag conveyor belt.

[0006] Above the outlet of the strip pack pusher is a first pusher plate that pushes the strip packs on the pusher plate to the receiving plate of the feeding station. Above the discharge station is a second pusher plate that pushes the strip packs on the receiving plate of the discharge station to the strip pack conveyor belt and a third pusher plate that pushes the strip packs on the strip pack conveyor belt to the outside.

[0007] By adopting the above technical solution, the present invention can reverse the direction of the bar package during the feeding process, replenish the material according to the specific material shortage of the receiving plate, and automatically return the replenishing plate after replenishment. It integrates the functions of reversing, replenishing and returning the material in bar package feeding to ensure that the bar package feeding is not short of material, and the action structure is simple.

[0010] like Figure 1-5As shown, the bar package reversing feeding mechanism of the present invention includes a reversing feeding plate 4. The reversing feeding plate 4 rotates in 90-degree increments during operation. The reversing feeding plate 4 is arranged circumferentially with one feeding station, two replenishing stations, and one discharging station. Each station has a receiving plate 5 fixedly installed on the reversing feeding plate 4. Each receiving plate 5 has twelve receiving grooves 12 arranged horizontally. The feeding station faces the outlet of the bar package pusher 10, which has twelve receiving grooves 12 arranged horizontally. The strip-shaped material channel 11 is set up with twelve channels. Each channel 11 of the strip-shaped package pusher 10 is equipped with a sensor to detect whether there is a strip package 101 in that channel 11. Above the outlet of the strip package pusher 10, there is a first pusher plate 7 that pushes the strip packages 101 on the pusher 10 to the receiving plate 5 at the feeding station. The discharge station faces the strip package conveyor belt 1. The strip package conveyor belt 1 is driven by a conveyor belt servo motor to make a circular intermittent motion. Equally spaced strip grooves 3 are arranged, with the spacing of the strip grooves 3 equal to the spacing of the receiving grooves 12. Twelve strip grooves 3 constitute a set of conveying units. A set of conveying units is set on a chain link seat 2, which is connected to the strip bag conveyor belt 1. Above the discharge station, there is a second pusher plate 9 that pushes the strip bag 101 on the receiving plate 5 of the discharge station to the strip bag conveyor belt 1, and a third pusher plate 8 that pushes the strip bag 101 on the strip bag conveyor belt 1 to the outside. The first pusher plate 7 is composed of... The first pusher plate cylinder 18 is pushed up and down, the first mounting base 19 of the first pusher plate cylinder 18 is pushed back and forth by the first rodless cylinder 20, the second pusher plate 9 is pushed up and down by the second pusher plate cylinder 15, the second mounting base 14 of the second pusher plate cylinder 15 is pushed back and forth by the second rodless cylinder 17, and the third pusher plate 8 is pushed up and down by the third pusher plate cylinder 16. The third pusher plate cylinder 16 is fixedly mounted on the second mounting base 14. Both receiving plates 5 at the two replenishment stations are equipped with replenishment plates 6 on their outer sides. The replenishment plates 6 are mounted on the transverse slide 27, which is controlled by a replenishment servo motor to move laterally. The replenishment plates 6 have twelve replenishment slots 13 arranged horizontally, corresponding to the receiving slots 12 on the receiving plates 5. Above the replenishment plates 6 is a replenishment push plate 24 that pushes the strip package 101 on the replenishment plates 6 to the receiving plates 5 at the replenishment stations. The replenishment push plate 24 is fixedly mounted on the slider support plate 22, which is pushed by a third rodless cylinder 25. The third rodless cylinder 25 is fixed on the feeding push plate seat 26. The feeding push plate seat 26 is controlled by the push plate seat servo motor to move horizontally. Above the feeding station, there is also a return push plate 21 that pushes the strip package 101 on the feeding station receiving plate 5 to the feeding plate 6. The return push plate 21 is pushed up and down by the return push plate cylinder 23. The return push plate cylinder 23 is installed on the slider support plate 22. The sensor, conveyor belt servo motor, feeding servo motor, push plate seat servo motor are electrically connected to the PLC.

[0011] The working process of this invention is as follows: At the outlet of the strip package pusher 10, the first pusher plate 7 pushes the strip package 101 onto the receiving plate 5 at the feeding station. Previously, the sensor had sent the information on which strip channel 11 was short of material to the PLC. The reversing feeder 4 rotates 90 degrees. If the first and fourth channels of the strip channel 11 were short of material, then the corresponding receiving slots 12 of the first and fourth channels of the receiving plate 5 would also be short of material. Therefore, at the two replenishment stations, the PLC replenishes the material according to the replenishment plate 6. The status of the strip package 101 stored in the trough 13 and the position of the replenishment trough 13 are calculated, and then signals are sent to control the replenishment servo motor and the pusher plate servo motor to perform corresponding actions. This aligns the replenishment trough 13 with the strip package 101 and the replenishment pusher plate 24 with the material-deficient receiving trough 12. Then, through the pushing action of the replenishment pusher plate 24, the strip package 101 on the replenishment plate 6 is pushed to the receiving plate 5, so that the material-deficient receiving trough 12 on the receiving plate 5 is filled with strip packages. Thus, at the discharge station, the second pusher... When the material plate 9 moves, it pushes the strip package 101 on the receiving plate 5 at the discharge station into the strip groove 3 of the strip package conveyor belt 1, where it is intermittently conveyed by the strip package conveyor belt 1, and the strip groove 3 is never short of material. During the above process, if the sensor detects that at least three strip material channels 11 are short of material, then the replenishing push plate 24 will not push the material. Moreover, after the second push plate 9 pushes the strip package 101 onto the strip package conveyor belt 1, the third push plate 8 immediately moves to push the strip package 1 onto the strip package conveyor belt 1. The strip package 101 is pushed into the external collection box for collection, awaiting subsequent use. During this process, the strip package conveyor belt 1 does not perform any conveying action. During this process, when it is found that the material trough 13 of the replenishment plate 6 is empty of strip packages 101, the receiving plate 5 at the receiving station of the strip package 101, upon reaching the replenishment station, does not activate the replenishment push plate 24. Instead, the return push plate 21 activates to push all the strip packages on the receiving plate 5 onto the replenishment plate 6, restoring the replenishment plate 6 to a full state. Repeating the above actions completes the reversing, replenishment, and automatic return actions of the strip package feeding of this invention, ensuring that the strip package feeding is not lacking material, and the action structure is simple.
