Description

Technical Field

[0001] This utility model relates to the field of production and conveying technology, specifically to a conveying device for powder packaging products. Background Technology

[0002] In powder packaging, such as paint powder, the powder is first bagged into individual bags, then the powder bags are filled into finished product drums / bags, and finally the finished product drums / bags are stacked. In highly automated workshops, this process has been fully automated. The powder is automatically fed to the packaging machine for bagging and sealing. After being sealed, the powder packaging bags fall onto the conveyor line and are gradually conveyed by multiple conveyor lines to the assembly conveyor line at a greater distance. The assembly conveyor line has a process for filling the powder packaging bags into finished product drums / bags. After the finished product is formed, it continues to be conveyed along the finished product assembly conveyor line to the stacking station.

[0003] In the entire automated production process, the upstream and downstream processes are interconnected, resulting in high production efficiency. However, if the downstream process (packing barrels / bags, palletizing, etc.) malfunctions and the production line stops operating, the packaging machine is still continuously bagging and sealing the powder because it is connected to the upstream process. The packaging machine usually cannot be stopped, which leads to the accumulation of powder packaging bags on the production line, requiring manual handling. This increases labor costs, and the excessive accumulation of semi-finished products also brings additional quality risks. Utility Model Content

[0004] The present invention aims to provide a conveying device for powder packaging products, so as to solve the problem that when the downstream process of the existing packaging production line fails, the front-end powder bagging and packaging machine cannot be stopped, resulting in continuous accumulation of packaging bags that require manual intervention.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A conveying device for powder packaging products includes a packaging output conveyor line, a finished product receiving and packing pre-conveying conveyor line, and a finished product assembly line. The finished product assembly line is connected to the end of the finished product receiving and packing pre-conveying conveyor line. It also includes a forward and reverse conveyor line disposed between the packaging output conveyor line and the finished product receiving and packing pre-conveying conveyor line. The conveying direction of the forward and reverse conveyor line is perpendicular to the conveying direction of both the packaging output conveyor line and the finished product receiving and packing pre-conveying conveyor line. A temporary storage bin is provided at the end of the forward and reverse conveyor line away from the finished product receiving and packing pre-conveying conveyor line. When the forward and reverse conveyor line rotates forward, the material is sent from the packaging output conveyor line to the finished product receiving and packing pre-conveying conveyor line via the forward and reverse conveyor line. When the forward and reverse conveyor line rotates in reverse, the material is sent to the temporary storage bin.

[0007] When a malfunction occurs in the finished product assembly line, the finished product assembly line stops working; the end of the finished product receiving conveyor is equipped with a sensor to detect whether the material is stagnant, and also includes a controller. The controller is used to control the finished product receiving conveyor to pause conveying when the sensor at the end of the finished product receiving conveyor detects that the material is stagnant, and to control the forward and reverse conveyors to reverse.

[0008] The principle and advantages of this solution are as follows: When the material sensor at the end of the pre-packaging conveyor detects a material stoppage, it indicates that the finished product assembly line, which is the subsequent process of the production line, has malfunctioned and stopped conveying. At this time, the controller controls the pre-packaging conveyor to pause conveying and controls the forward and reverse conveyors to reverse, so that the material sent from the packaging output conveyor is no longer sent to the pre-packaging conveyor, avoiding the accumulation of material on the pre-packaging conveyor. Instead, the material is sent to the temporary storage warehouse for storage through the reverse forward and reverse conveyors, avoiding the problem of needing manual intervention to handle a large amount of accumulated material.

[0009] Preferably, as an improvement, the finished product receiving and loading conveyor line includes two conveyor sections. Each conveyor section is equipped with a sensor at the end to detect material stagnation. When the corresponding sensor detects material stagnation in each conveyor section, the controller controls the corresponding conveyor section to stop conveying.

[0010] The controller will only reverse the forward and reverse conveyor lines when both conveyor sections detect that the material has stopped moving.

[0011] Beneficial effects: This allows more materials to be sent to the pre-finished product receiving conveyor line without causing accumulation problems. This reduces the amount of material sent to the temporary storage warehouse and ensures that there are enough materials available for continuous production after the subsequent finished product assembly line resumes operation. (When the forward and reverse conveyor lines reverse, the materials that were originally destined for the pre-finished product receiving conveyor line are also sent to the temporary storage warehouse, causing gaps on the forward and reverse conveyor lines. However, since the pre-finished product receiving conveyor line is a two-section line, there are enough materials on both sections, ensuring that even if the materials on the forward and reverse conveyor lines are not immediately sent to the pre-finished product receiving conveyor line, the finished product assembly line still has enough materials for immediate production.)

[0012] Preferably, as an improvement, the packaging output conveyor line is a three-section conveyor line, which includes a first conveyor belt, a second conveyor belt and a third conveyor belt arranged in sequence. The second conveyor belt is a weighing conveyor line, which is used to weigh the material while it is being conveyed. When the weight weighed by the weighing conveyor line exceeds the threshold set by the controller, the controller controls the connected alarm to issue an alarm signal.

[0013] Preferably, as an improvement, the first, second, and third conveyor belts are all inclined upward conveying methods with a lower front end and a higher rear end, so that the material goes uphill and then falls down in a cycle on each conveyor belt. This can control the center of gravity of the powder in the packaging bag, making it relatively stable and facilitating the weighing and measurement of the weighing conveyor line.

[0014] Preferably, as an improvement, the pre-collection conveyor line is also an inclined upward conveyor with a low front end and a high rear end, which helps the powder packaging bags fall into the finished product barrels / bags on the finished product assembly line at basically the same center of gravity position.

[0015] Preferably, as an improvement, the temporary storage bin is a storage bucket with casters installed at the bottom, which facilitates the transfer of materials in the temporary storage bin. Attached Figure Description

[0020] The following detailed description illustrates the specific implementation method:

[0021] The reference numerals in the accompanying drawings include: packaging output conveyor line 10, first conveyor belt 11, second conveyor belt 12, third conveyor belt 13, forward and reverse conveyor line 20, finished product receiving and packing conveyor line 30, conveyor section one 31, conveyor section two 32, sensor 311, sensor 321, finished product assembly line 40, temporary storage warehouse 50, packaging machine 100, and drum unloader 200.

[0022] The basic implementation examples are as follows: Figures 1 to 4 As shown.

[0023] A conveying device for powder packaging products includes a packaging output conveyor line 10, a forward and reverse conveyor line 20, a finished product pre-collection conveyor line 30, and a finished product assembly line 40 arranged sequentially. The conveying direction of the forward and reverse conveyor line 20 is perpendicular to the conveying directions of the packaging output conveyor line 10 and the finished product pre-collection conveyor line 30. When rotating forward, the forward and reverse conveyor line 20 conveys the material from the end of the packaging output conveyor line 10 to the front end of the finished product pre-collection conveyor line 30 (in this embodiment, the front end or first end is the input end of the conveyor line, and the end is the output end). A temporary storage bin 50 is provided at the end of the forward and reverse conveyor line 20 away from the finished product pre-collection conveyor line 30. When the forward and reverse conveyor line 20 rotates in reverse, the material is sent to the temporary storage bin 50. In this embodiment, the temporary storage bin 50 is a storage bin with wheels installed at the bottom, and the top of the storage bin is open.

[0024] The finished product assembly line 40 is connected to the end of the finished product receiving and packing conveyor line 30. The finished product assembly line 40 is perpendicular to the finished product receiving and packing conveyor line 30. The input end of the finished product assembly conveyor line is equipped with a barrel unloader 200. The barrel unloader 200 is used to place the barrel containing the powder packaging bag. The barrel unloader 200 is used to place the barrel on the finished product assembly line 40 so that the material sent from the finished product receiving and packing conveyor line 30 can be placed into the barrel for packing by automated equipment or manual operation.

[0025] In a specific implementation, the packaging output conveyor line 10 is a three-section conveyor line, including a first conveyor belt 11, a second conveyor belt 12, and a third conveyor belt 13 arranged sequentially. The second conveyor belt 12 is a dynamic weighing conveyor line (in the prior art, a dynamic weighing conveyor line is also called a belt-type dynamic weighing scale; this is prior art, and its specific structure is not shown in this embodiment), used for weighing materials during transport. The first conveyor belt 11, the second conveyor belt 12, and the third conveyor belt 13 all use an inclined upward conveying method with a lower front end and a higher rear end.

[0026] The finished product receiving and loading conveyor line 30 includes two conveyor sections, referred to as conveyor section one 31 and conveyor section two 32. The beginning of conveyor section one 31 receives the material sent from the forward and reverse conveyor lines, and the end of conveyor section one 31 sends the material to the beginning of conveyor section two 32. Sensors for detecting material stagnation are installed at the ends of both conveyor sections (sensor 311 and sensor 321, respectively). In this embodiment, the sensor is a through-beam photoelectric switch.

[0027] It also includes a controller. When the finished product assembly line 40 malfunctions, the material will stop at the end of the second conveyor section 32. The sensor 321 at the end of the second conveyor section 32 detects the material stoppage and controls the second conveyor section 32 to stop conveying through the controller. After the second conveyor section 32 stops conveying, the material sent from the first conveyor section 31 to the second conveyor section 32 stops at the docking area of ​​the first conveyor section 31 and the second conveyor section 32 (the docking area is also the end of the first conveyor section 31). The sensor 311 detects the material stoppage. At this time, both the sensor 311 and the sensor 321 detect the material stoppage and control the forward and reverse conveyor line 20 to reverse through the controller, so that the powder packaging bags continuously produced by the packaging machine 100 are sent to the temporary storage warehouse 50 for placement.

[0028] The two conveyor sections of the finished product collection and loading conveyor line 30 also adopt an inclined upward conveying method with a lower front end and a higher rear end.

[0029] The working process of this embodiment is as follows:

[0030] During normal operation: the forward and reverse conveyor line 20 rotates forward, and the material is sent from the packaging output conveyor line 10 to the finished product receiving conveyor line 30 via the forward and reverse conveyor line 20, and finally enters the finished product assembly production line 40.

[0031] During troubleshooting: When the finished product assembly line 40 stops due to a fault, the sensor 321 at the end of the finished product receiving conveyor 30 detects that the material is stuck. The controller first stops the operation of the second conveyor section 32. If both the sensors 311 and 321 of the two conveyor sections of the finished product receiving conveyor 30 detect that the material is stuck, the controller controls the forward and reverse conveyor 20 to reverse and send the material to the temporary storage bin 50 for temporary storage to avoid the material from accumulating on the conveyor line.

[0032] During the conveying process, the dynamic weighing conveyor line 12 monitors the weight of the material in real time. If the weight exceeds the set threshold, the controller triggers an alarm.

[0033] This embodiment achieves automatic material storage in case of failure through the cooperation of forward and reverse conveyor line 20 and temporary storage bin 50, reducing manual intervention and improving the automation level and stability of the production line.
