Description

Technical Field

[0001] This utility model relates to the field of ton bag sub-packaging technology, and in particular to a fully automatic ton bag sub-packaging conveyor. Background Technology

[0002] A ton bag, also known as a bulk container bag or woven bag, is a large plastic bag used for storing and transporting bulk materials. These ton bags are typically made of polypropylene fiber, featuring high strength, wear resistance, water and moisture resistance, and ease of loading and unloading. Ton bags are usually designed in a cuboid or rectangular shape, and one or more openings can be provided on the surface to facilitate the pouring or unloading of bulk materials such as chemicals, grains, minerals, and building materials. Furthermore, ton bags can be suspended using lifting rings or other lifting devices for easy transport.

[0003] Currently, the industry has limited conditions for automated material conveying in ton bag packaging. Several key challenges exist in the material conveying process of fully automated ton bag unpacking machines, including the following:

[0004] (1) High equipment inlet: It is challenging to transport materials from a single ton bag to a high unpacking machine inlet;

[0005] (2) Problem of stacking ton bags: incoming materials are often stacked in two bags, but unpacking machines can only process single bags of materials, which requires an effective unpacking and repacking solution;

[0006] (3) External stain cleaning problem: There are often stains on the surface of ton bags. It is necessary to avoid bringing the stains into the material during the unpacking process to ensure the purity of the material. Currently, the stains on the surface of the ton bags are usually cleaned manually.

[0007] Although fully automated ton bag unpacking production lines offer the advantage of high automation, manual intervention is still required for tasks such as cleaning, handling, and conveying incoming materials. To achieve a higher level of automation and reduce the need for manual operation, this application urgently requires the design of a fully automated ton bag repacking machine, positioned in front of the fully automated ton bag repacking conveyor, to address the aforementioned problems of existing fully automated ton bag unpacking machines and provide a reliable guarantee for the full automation of ton bag unpacking production lines. Utility Model Content

[0008] The purpose of this invention is to overcome the above-mentioned shortcomings of the prior art and provide a fully automatic ton bag sub-packaging and conveying machine that is easy to operate and has high material purity.

[0009] The technical solution of this utility model is: a fully automatic ton bag repackaging conveyor, including a machine body, wherein the machine body is provided with an elevator for conveying stacked ton bags to a target position and a bag gripping mechanism for performing repackaging operations on the ton bags; the machine body is provided with a dust removal device along the conveying path of the elevator.

[0010] Furthermore, the elevator is equipped with a roller conveyor line, which is used to transport ton bags as the elevator rises and falls.

[0011] Furthermore, the machine body is equipped with an automatic opening and closing inlet door and outlet door; stacked ton bags enter the roller conveyor line through the inlet door; when the roller conveyor line conveys to a designated height, it connects to an external conveyor line through the outlet door; the external conveyor line connects to the internal conveyor line of the ton bag unpacking machine.

[0012] Furthermore, a barcode scanning device for detecting whether the incoming material is correct is provided on the outside of the feeding gate.

[0013] Furthermore, the bag-grabbing mechanism is installed on the top of the inner cavity of the machine body; the dust removal device is installed on the side wall of the inner cavity of the machine body.

[0014] Furthermore, dust removal devices are provided on both sides of the machine body to remove dust from the front and back of the ton bag, respectively.

[0015] Furthermore, the dust removal device is a pulse dust collector for cleaning stains on the outside of the ton bag, including an air tank. The air inlet of the air tank is used to receive compressed gas, and the air outlet of the air tank is connected to at least one blow pipe via a pulse solenoid valve. The blow pipe extends along the length of the ton bag and has multiple spray holes on it.

[0016] Furthermore, the bag-grabbing mechanism is a bag-grabbing robot arm, used to grab the upper layer of bags after multiple ton bags are delivered to the target position to realize the repackaging operation.

[0017] Furthermore, the elevator is equipped with a first detection position for determining whether the roller conveyor has reached a specified height, and a second detection position for determining whether the roller conveyor has risen a second time to the gripping position of the bag-grabbing mechanism.

[0018] Furthermore, the machine body is also equipped with a control system, which includes a controller for electrically connecting to the electrical control devices corresponding to the elevator, bag grabbing mechanism and dust removal device.

[0019] The beneficial effects of this utility model are:

[0020] (1) By setting up an elevator and a bag grabbing mechanism, the elevator can be used to raise the stacked ton bags to the position corresponding to the internal conveying line of the unpacking machine, and the bag grabbing mechanism can be used to perform the sub-packing operation, thereby realizing the conveying of a single ton bag material to a higher unpacking machine inlet. The operation is simple and solves the problems of ton bag stacking and high inlet in the material conveying process of the existing fully automatic ton bag unpacking machine.

[0021] (2) By setting up a dust removal device, the external stains of the ton bag can be cleaned during the rising process, so as to prevent the stains from being brought into the material during the unpacking process after the ton bag is sent to the unpacking machine, thereby ensuring the purity of the material.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] like Figures 1-3 As shown: A fully automatic ton bag repackaging conveyor is located in front of the unpacking machine 8. It includes a machine body 1, an elevator 2 located inside the machine body 1 for conveying stacked ton bags 6 to the target position, a bag-grabbing robot 3 located above the elevator 2, and a roller conveyor line 4 that cooperates with the elevator 2. A dust removal device 5 is provided on the conveying path of the elevator 2 for cleaning stains on the outside of the ton bags. The bag-grabbing robot 3 is used to grab the upper ton bags to perform repackaging operations.

[0029] Specifically, in this embodiment, the stacked ton bags are usually two stacked ton bags 6. In order to facilitate the transportation of the ton bags, it is preferable to place the two ton bags on a pallet (not shown in the figure) for transportation.

[0030] In this embodiment, the machine body 1 is a structural main body used to support and fix the bag-grabbing robot and the dust removal device, and to cover the entire sub-packaging equipment to prevent equipment failure and material falling during operation, thereby ensuring a clean and safe working environment. The elevator 2 is installed in the inner cavity of the machine body 1 and is covered by the machine body 1; the bag-grabbing robot 3 is installed on the top of the inner cavity of the machine body 1; and the dust removal device 5 is installed on the side wall of the inner cavity of the machine body 1.

[0031] The machine body 1 is equipped with a feed roller shutter 11 and a discharge roller shutter 12 for material entry and exit. The roller shutters can open and close automatically to prevent external environmental pollutants from entering the equipment. Since the automated structure of the roller shutters is existing technology, it will not be described in detail here. Stacked multi-ton bags enter the roller conveyor line 4 through the feed roller shutter 11. The roller conveyor line 4 connects to the external conveyor line 7 via the discharge roller shutter 12, and the external conveyor line 12 connects to the internal conveyor line of the unpacking machine 8. It is understood that a barcode scanning device, such as a barcode scanner, can also be installed on the outside of the feed roller shutter to scan the identification code on the ton bags to confirm whether the incoming material is correct. If correct, the control system automatically opens the feed roller shutter; if incorrect, it does not open and an alarm can be triggered.

[0032] In this embodiment, the body 1 can be designed with any structure capable of enclosing the subcontracting equipment, such as a frame structure composed of supporting columns and beams. The frame is provided with a plate for sealing the inner cavity, and inlet roller shutters and outlet roller shutters are respectively provided at positions corresponding to the roller conveyor line and the external conveyor line. It is understood that at least one maintenance door can also be provided on the body.

[0033] In this embodiment, the elevator 2 is a lifting device with its own roller conveyor. It mainly includes a lifting frame, a lifting mechanism connected to both sides of the lifting frame, and a drive mechanism that controls the lifting mechanism's movement. The roller conveyor 4 is located between the lifting frames and can move up and down with the lifting mechanism. When material enters and is positioned on the roller conveyor 4, the lifting mechanism drives the roller conveyor 4 to rise to a designated height, which is consistent with the height of the external conveyor 7 and the internal conveyor of the unpacking machine 8. Additionally, it rises a second time to the gripping position of the bag-grabbing robot, so that the bag-grabbing robot 3 can place the gripped upper-layer ton bags onto the elevator. Photoelectric sensors or limit switches are typically installed at the designated height of the elevator 2 and at the gripping position of the bag-grabbing robot. Once the roller conveyor 4 reaches the designated height, a signal is detected and sent to the control system. The elevator in this embodiment can be a chain elevator or a belt elevator, etc. Since the mechanical structure of the elevator is already conventional technology in the mechanical field, it will not be described in detail here.

[0034] In this embodiment, the bag-grabbing robot 3 can grab the upper-layer ton bags on the elevator 2, move them up and down, and transport them to the target position. Its main function is: the bag-grabbing robot 3 descends to grab the upper-layer ton bags on the elevator 2, holds them in the air, and after the lower-layer ton bags are conveyed, places the upper-layer ton bags onto the roller conveyor line. Since the structure of the bag-grabbing robot is roughly the same as that of existing ton-bag grabbing robots, it will not be described in detail here. The bag-grabbing robot can also be equipped with a successful grab detection device, such as a force sensor or camera, which connects to the control system to achieve the detection function.

[0035] In this embodiment, the dust removal device 5 is a pulse dust collector used to clean the external stains of the ton bags. This embodiment can use an existing small pulse dust collector. For example, a pulse dust collector mainly includes a main structure and a pulse jet device, or it can only include the pulse jet device. The pulse jet device includes an air tank 51, whose inlet is used to receive compressed gas. The outlet of the air tank is connected to a pulse jet pipe 53 via a pulse solenoid valve 52. The pulse jet pipe 53 extends along the length of the ton bag 6 and has multiple nozzles. Compressed air is blown directly onto the surface of the ton bag through the nozzles on the pulse jet pipe 53 to clean the surface of the ton bag. Preferably, this embodiment has pulse dust collectors on both sides of the machine body to perform pulse dust removal on the front and back of the ton bags respectively. Each pulse dust collector's air tank 51 is connected to two pulse jet pipes 53, corresponding to the upper and lower layers of ton bags 6 respectively, performing dust removal operations simultaneously.

[0036] This embodiment also includes a control system, which comprises a controller. The control terminals of the infeed roller shutter and the discharge roller shutter are both connected to the output terminal of the controller. The detection sensors corresponding to the detection terminals of the barcode scanner, the bag-grabbing robot, the specified height detection terminal of the elevator, and the bag-grabbing robot's gripping position detection terminal are all connected to the input terminal of the controller. The output terminal of the controller is also connected to the drive terminal of the roller conveyor, the drive terminal of the elevator, the drive terminal of the bag-grabbing robot, and the pulse solenoid valve of the pulse dust collector. The control system can also communicate bidirectionally with the monitoring terminal through a communication module to achieve visual management and monitoring.

[0037] The working principle of this embodiment is as follows:

[0038] (1) The pallet and the two stacked ton bags on the pallet are transported to the feed roller shutter door 11 of the subcontracting conveyor by the automatic AGV (handling robot) 9. The incoming material is identified by the barcode scanner. If it is correct, the feed roller shutter door 11 is opened automatically.

[0039] (2) The AGV delivers the ton bag to the roller conveyor line 4 through the feeding shutter 11, starts the roller conveyor line 4 to position the material, the AGV exits the sub-packaging conveyor, and the feeding shutter 11 closes.

[0040] (3) Control the elevator 2 to drive the roller conveyor line 4 and the stacked ton bags on the roller conveyor line to start rising. At the same time, the pulse dust collector is turned on. During the rising process, the dirt on the outside of the ton bags is cleaned. When the roller conveyor line rises to the specified height, it stops. The specified height is consistent with the height of the external conveyor line and the height of the internal conveyor line of the unpacking machine.

[0041] (4) The gripper of the bag grabbing robot 3 above descends and grabs the upper ton bag located on the elevator 2 into the air. The gripper is equipped with a device to detect successful grabbing. After grabbing, it sends a signal to the control system to control the opening of the discharge roller shutter door 12.

[0042] (5) After the discharge roller shutter door 12 is opened, the roller conveyor line 4, the external conveyor line 7, and the internal conveyor line of the unpacking machine 8 of the elevator are opened simultaneously to transport the material to the inside of the unpacking machine 8. After the unpacking machine 8 collects the material, it returns the pallet to the elevator 2 through the roller conveyor line 4.

[0043] (6) The elevator 2 rises to the grabbing height of the bag grabbing robot 3 for the second time. The bag grabbing robot 3 descends and places the upper ton bag that was originally grabbed on the pallet. The elevator 2 descends to the conveying position, i.e. the designated height.

[0044] (7) The roller conveyor 4 runs to send the ton bag into the unpacking machine 8. After the unpacking is completed, the pallet returns to the elevator 2. After the elevator 2 lowers the pallet to the bottom, the feeding roller shutter 11 opens, the pallet returns to the material picking position, and the AGV picks up the pallet.
