Description

Technical Field

[0001] This invention relates to a method for batch unpacking of finished packaging bags. Background Technology

[0002] High-speed packaging machines that continuously and rapidly manufacture and transport small packaging bags, such as the high-speed packaging machine disclosed in Chinese Patent No. CN102874423A entitled "High-Speed ​​Fully Automatic Packaging Machine" (hereinafter referred to as "high-speed packaging machine"), include a frame and a film feeding device, a bag forming device, a longitudinal sealing device, a filling device, a sealing device, a cutting device, a bag feeding device, and a finished product output device respectively mounted on the frame. The aforementioned film feeding device, bag forming device, longitudinal sealing device, sealing device, bag feeding device, and finished product output device are arranged sequentially along the conveying direction of the packaging material. The filling device is located above the longitudinal sealing device, and the finished product output device is located below the bag feeding device. Therefore, it can form packaging bags from packaging film, fill and package the packaging bags, and produce finished packaging bags containing materials (hereinafter referred to as finished packaging bags), thus achieving high-speed fully automatic packaging.

[0003] However, after more than a decade of development, continuous improvements have been made to the various mechanisms of this high-speed packaging machine, resulting in a continuous increase in the speed at which it manufactures and transports packaged products. If the packaged products are still output through a single channel, subsequent processing equipment (such as sorting, boxing, and other packaging bag processing equipment, which have relatively slow processing speeds and cannot significantly improve work efficiency) will be unable to meet the demand. Therefore, further improvements are needed to enable the bag feeding device of the high-speed packaging machine to transport packaged products through multiple channels. Summary of the Invention

[0004] The purpose of this invention is to provide a method for batch unpacking of finished packaging bags, which enables continuously conveyed finished packaging bags to be transported in batches through multiple channels. The technical solution adopted is as follows:

[0005] A method for batch unpacking of finished packaging bags, characterized by the following steps:

[0006] (1) Set up multiple finished product channels for packaging bags;

[0007] (2) The finished packaging bags conveyed by the bag feeding device of the packaging machine are respectively matched with the finished packaging bag channels;

[0008] (3) Send the finished packaging bag that has been moved to the top of the finished packaging bag channel and is corresponding to the finished packaging bag channel into the finished packaging bag channel;

[0009] All the finished packaging bag channels in step (1) are distributed sequentially along the direction of finished packaging bag conveying, and the distance between any two adjacent finished packaging bag channels is equal to the width of the finished packaging bag.

[0010] The method of step (2) to correspond the finished packaging bags to each finished packaging bag channel is as follows: the finished packaging bags conveyed by the bag feeding device of the packaging machine are alternately assigned to the front conveying group and the rear conveying group in sequence. The front conveying group and the rear conveying group move to the top of multiple finished packaging bag channels and correspond one by one with the entrance of these finished packaging bag channels.

[0011] Step (3) involves alternately feeding multiple finished packaging bags from the front conveyor group and the rear conveyor group downwards into the inlets of the finished packaging bag channels. That is, when multiple finished packaging bags from the front conveyor group are conveyed directly above the inlets of the multiple finished packaging bag channels, these finished packaging bags are simultaneously detached from the clamping parts of the bag feeding device of the packaging machine and fed into the multiple finished packaging bag channels respectively. Since multiple finished packaging bags from the rear conveyor group need to move a distance equal to the width of a finished packaging bag to reach the inlets of the multiple finished packaging bag channels, after the front conveyor group has finished feeding multiple finished packaging bags, after a period of time, these finished packaging bags from the rear conveyor group move to the inlets of the multiple finished packaging bag channels, and then are detached from the clamping parts of the bag feeding device of the packaging machine and fed into the multiple finished packaging bag channels respectively. After another period of time, after the next batch of multiple finished packaging bags from the front conveyor group are conveyed directly above the inlets of the multiple finished packaging bag channels, the front conveyor group continues to feed finished packaging bags. This process alternates between the front conveyor group and the rear conveyor group to deliver the finished packaged bags.

[0012] In a preferred embodiment, the specific steps of step (2) of sequentially and alternately distributing the finished packaging bags conveyed by the bag feeding device of the packaging machine to the front conveying group and the rear conveying group are achieved by using a continuously swinging distribution device to alternately distribute the finished packaging bags to the front and rear sides of the separator.

[0013] A better solution is that the specific steps of step (3) of alternately feeding multiple finished packaging bags from the front conveyor group and the rear conveyor group into the inlet of each finished packaging bag channel are as follows: a servo motor is used to drive the paddle to rotate, so that the paddle cooperates with the front or rear side of the separator to pull the finished packaging bag from the bag clamp of the bag feeding device of the packaging machine and feed it down into the corresponding finished packaging bag channel inlet located below.

[0014] A better embodiment is that the lower front side of the separator is provided with a front transfer chute for feeding the torn-off finished packaging bag into the corresponding finished packaging bag channel entrance, and the lower rear side of the separator is provided with a rear transfer chute for feeding the torn-off finished packaging bag into the corresponding finished packaging bag channel entrance.

[0015] The beneficial effects of this invention compared to the prior art are that, by setting up multiple finished packaging bag channels and dividing the conveyed finished packaging bags into front conveying groups and rear conveying groups according to odd and even numbers, each corresponding to a finished packaging bag channel, and alternately feeding the finished packaging bags from the front conveying group and the rear conveying group into the corresponding finished packaging bag channels, the work efficiency is greatly improved, enabling the conveying of finished packaging bags to keep up with the speed of the packaging machine's production of finished packaging bags, thus meeting the processing needs brought about by the ever-increasing production capacity of packaging machines.

[0020] A method for batch unpacking of finished packaging bags according to one embodiment of this application includes the following steps:

[0021] (1) Set up multiple finished product channels for packaging bags 1;

[0022] (2) The finished packaging bags 3 conveyed by the bag feeding device 2 of the packaging machine are respectively matched with each finished packaging bag channel 1;

[0023] (3) The finished packaging bag 3 that is moved to the top of the entrance of each finished packaging bag channel 1 and corresponds to the finished packaging bag channel 1 is sent into the finished packaging bag channel 1.

[0024] In this embodiment, the finished product channel 1 of the packaging bag can be set at a suitable location as needed, and the number of finished product channels 1 of the packaging bag can also be set as needed.

[0025] like Figure 1As shown, in an alternative embodiment of this application, a packaging production line employing the above-described method has a film feeding mechanism that conveys the film. After folding and forming, the film is fed into the longitudinal sealing and filling mechanism on the right side to complete the longitudinal sealing and filling process. The film is then conveyed to the left, and after transverse sealing and cutting to form the finished package, it is sequentially clamped and conveyed to the left by the bag-feeding device 2's bag clamping components 201. A second batch bag removal method is used to convey the film downwards in batches, followed by stacking and boxing. This batch bag removal method is as follows:

[0026] like Figure 1-4 As shown, in an optional embodiment of this application, all the finished packaging bag channels 1 in step (1) are distributed sequentially along the direction of conveying the finished packaging bag 3, and the distance between any two adjacent finished packaging bag channels 1 is equal to the width of the finished packaging bag 3.

[0027] like Figure 1-4 As shown, in an optional embodiment of this application, the method of step (2) corresponding the finished packaging bags 3 to each finished packaging bag channel 1 is as follows: the finished packaging bags 3 conveyed by the packaging machine bag feeding device 2 are alternately distributed to the front conveying group and the rear conveying group in sequence. The front conveying group and the rear conveying group move to the top of multiple finished packaging bag channels 1 and correspond one-to-one with the entrances of these finished packaging bag channels 1. The method of step (3) is as follows: the multiple finished packaging bags 3 of the front conveying group and the rear conveying group are alternately fed downward into the entrances of each finished packaging bag channel 1. In other words, when multiple finished packaging bags 3 of the front conveyor group are conveyed to the entrance of multiple finished packaging bag channels 1, these finished packaging bags 3 are simultaneously detached from the clamping parts 201 of the bag feeding device 2 of the packaging machine and fed into the multiple finished packaging bag channels 1 respectively. Since multiple finished packaging bags 3 of the rear conveyor group need to move a distance equal to the width of one finished packaging bag 3 to reach the entrance of the multiple finished packaging bag channels 1, after the front conveyor group has finished conveying multiple finished packaging bags 3, after a period of time, these finished packaging bags 3 of the rear conveyor group move to the entrance of the multiple finished packaging bag channels 1, and then detach from the clamping parts 201 of the bag feeding device 2 of the packaging machine and fed into the multiple finished packaging bag channels 1 respectively. After another period of time, after the next batch of multiple finished packaging bags 3 of the front conveyor group are conveyed to the entrance of the multiple finished packaging bag channels 1 respectively, the front conveyor group continues to convey finished packaging bags 3. In this way, the work of conveying finished packaging bags 3 by the front conveyor group and the rear conveyor group is completed alternately.

[0028] like Figure 1-4As shown, in an optional embodiment of this application, the specific step of step (2) of alternately distributing the finished packaging bags 3 conveyed by the bag feeding device 2 of the packaging machine to the front conveying group and the rear conveying group is achieved by using a continuously swinging distribution device 5 to alternately distribute the finished packaging bags 3 to the front and rear sides of the separator 6. In this embodiment, the finished packaging bags 3 conveyed by the bag feeding device 2 of the packaging machine are arranged sequentially along the conveying direction. The finished packaging bags 3 in odd-numbered positions are sent to the front side of the separator 6 by the distribution device 5 to form the front conveying group, and the finished packaging bags 3 in even-numbered positions are sent to the rear side of the separator 6 by the distribution device 5 to form the rear conveying group.

[0029] like Figure 3 , 4 As shown, in one alternative embodiment of this application, the dispensing device 5 includes a dispensing slot that can reciprocate in a horizontal plane and a servo motor. The dispensing slot is mounted on the vertically upward-extending output shaft of the servo motor, allowing the left outlet of the dispensing slot to swing back and forth at the right inlet of the separator 6. Because the dispensing slot is an inclined groove whose width gradually decreases from right to left, the finished packaging bag 3 can always enter from the right side and be alternately dispensed to the front and rear sides of the separator 6 by the dispensing slot. In other alternative embodiments, a mechanical mechanism with similar functions can be used.

[0030] like Figure 1-4 As shown, in an optional embodiment of this application, the specific steps of step (3) of alternately feeding multiple finished packaging bags 3 of the front conveying group and the rear conveying group downward into the inlet of each finished packaging bag channel 1 are as follows: the servo motor 7 drives the lever 8 to rotate, so that the lever 8 cooperates with the front or rear side of the separator 6 to pull the finished packaging bag 3 off the bag clamp 201 of the bag feeding device 2 of the packaging machine and feed it downward into the corresponding finished packaging bag channel 1 inlet located below.

[0031] like Figure 1-4 As shown, in one alternative embodiment of this application, all the finished packaging bags 3 located on the front side of the separator 6 are simultaneously rotated by a servo motor 7 with multiple paddles 8 and engaged with the front side of the separator 6 to pull off these finished packaging bags 3 (i.e., the front conveyor group); all the finished packaging bags 3 located on the rear side of the separator 6 are simultaneously rotated by another servo motor 7 with multiple paddles 8 and engaged with the rear side of the separator 6 to pull off these finished packaging bags 3 (i.e., the rear conveyor group).

[0032] like Figure 1-4 As shown, in one alternative embodiment of this application, the lower front side of the separator 6 is provided with a front transfer groove 9 for feeding the torn-off finished packaging bag 3 into the inlet of the corresponding finished packaging bag channel 1, and the lower rear side of the separator 6 is provided with a rear transfer groove 10 for feeding the torn-off finished packaging bag 3 into the inlet of the corresponding finished packaging bag channel 1.

[0033] In this embodiment, all finished product channels 1 of the packaging bags can be set at appropriate locations as needed, and the number of finished product channels 1 can also be set as needed, but the spacing between any two adjacent finished product channels 1 is fixed. The bag-clamping components 201 of the bag-feeding device 2 do not require modification; the finished product packaging bags 3 held by them are pulled off and conveyed downwards, all accomplished by the servo motor 7 controlled by the control device. This batch bag removal method is mainly achieved by adding the aforementioned dedicated batch bag removal structure and using a control device for control.

[0034] Furthermore, it should be noted that the names of the various parts of the specific embodiments described in this specification may differ. All equivalent or simple variations made to the structure, features, and principles described in this invention are included within the scope of protection of this invention. Those skilled in the art can make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this invention or exceed the scope defined in these claims, all of which should fall within the scope of protection of this invention.
