Description

Technical Field

[0001] The present invention relates to the technical field of logistics packaging, in particular to a self-adaptive size packaging device and method for logistics packaging. Background Art

[0002] With the strengthening of the trend of global economic integration, the logistics industry has become the leading industry in promoting commercial development. The quality of commodity packaging is crucial in the logistics system, which directly affects the full play of the quality of each link of the logistics system. Modern packaging design should conform to the requirements of each link of the logistics system, and design based on this standard, highlighting the convenience of "transportation", "loading and unloading", "in-warehouse management", "intelligent identification", "information transmission" and other functions. As one of the components of logistics companies, packaging has a very close relationship with transportation, storage, handling, circulation and processing. Packaging is the end of production and the starting point of logistics.

[0003] At present, the main method of packaging items is to use boxes made of paper and other materials. Since the items generally need to be transported for a long time and over long distances after packaging, it is very important to protect the items during packaging. The traditional protection method is usually to fill the box with flexible materials such as sponge, but this type of protection cannot effectively position the items in the box. When the packaging box is transported over long distances, the items are easy to move around in the box, causing the items to easily collide with the inner wall of the packaging box, or even through the packaging box and the transport vehicle that transports the packaging box. There is also a protection method in the prior art of injecting foam into the box. When packaging the items, foam is injected into the packaging box. After the foam expands, it is wrapped around the upper and lower sides of the items. After expansion, the foam will form a groove that fits the item at the contact position of the upper and lower layers. Through the expansion, the foam will form a groove that fits the item. The expanded foam glue can be used to position the items in the packaging box. However, in the prior art, the injection of foam glue into the packaging box is generally done manually by staff. It is difficult to achieve precise matching between the injection amount of foam glue and the volume of the items and the internal volume of the packaging box. If the amount of foam glue injected is small, it is difficult for the foam glue to fill the interior of the packaging box after expansion, and it cannot effectively protect the items. If the amount of foam glue injected is large, the foam glue will overflow from the packaging box after expansion, and the excess foam glue needs to be cut off later, which increases the workload. For this reason, we propose an adaptive size packaging device and method for logistics packaging to solve the above problems. Summary of the invention

[0014] A method for using an adaptive size packaging device for logistics packaging, comprising the following steps:

[0015] S1, the programmable controller controls the packing box conveying mechanism and the article conveying mechanism to start, the conveying servo motor in the packing box conveying mechanism drives the conveying belt to rotate to convey the article conveying mechanism, and the conveying servo motor in the article conveying mechanism drives the conveying belt to rotate to convey the articles to be packaged;

[0016] S2. When the position sensor 2 detects the item packaging box, the packaging box conveying mechanism stops, and the programmable controller controls the electric telescopic rod 2 to drive the 3D scanner to move downward, extend the 3D scanner into the item packaging box, and drive the 3D scanner to move up and down in the item packaging box to scan the volume inside the item packaging box, and transmit the detection data to the programmable controller;

[0017] When the article to be packaged is transported by the article conveying mechanism, it passes through the article detecting mechanism, detects the article to be packaged through the detection grating in the article detecting mechanism, obtains the volume data of the outside of the article to be packaged, and transmits the detection data to the programmable controller. After the article packaging box and the article to be packaged are detected, the packaging box conveying mechanism and the article conveying mechanism are started to continue conveying;

[0018] S3, when the position sensor 1 on the packaging box conveying mechanism detects the article packaging box, the packaging box conveying mechanism stops; when the position sensor 3 on the article conveying mechanism detects the article to be packaged, the article conveying mechanism stops;

[0019] S4. The programmable controller sends a command to the three-axis moving module, and the three-axis moving module drives the connecting arm and the horizontal mounting plate to move, drives the foam glue dispensing mechanism to move to the top of the item packaging box, and then controls the foam glue dispensing mechanism to open, and injects the foam glue of the lower layer into the item packaging box. Then the three-axis moving module drives the connecting arm, the horizontal mounting plate and the adsorption mechanism to move, and the separation film in the placement frame is adsorbed by the adsorption mechanism, and the separation film is placed on the top of the foam glue of the lower layer in the item packaging box. Then the three-axis moving module drives the connecting arm, the horizontal mounting plate and the clamping mechanism The three-axis moving module controls the adsorption mechanism to adsorb the separation film and places the separation film on the top of the items to be packaged inside the item packaging box. Then, the three-axis moving module controls the foam glue dispensing mechanism to inject foam glue into the item packaging box again. The injection amount of the upper and lower layers of foam glue is determined by the programmable controller according to the external volume of the items to be packaged, the internal volume of the item packaging box and the expansion coefficient of the foam glue, so that the foam glue can just fill the interior of the item packaging box after injection.

[0020] S5. When the clamping mechanism clamps the packaged item, the clamping servo motor drives the bidirectional adjustment screw to rotate, thereby driving the two sets of locking clamps to move inward synchronously, and the two sets of locking clamps cooperate to clamp the packaged item;

[0021] S6. After two layers of foam glue are injected into the item packaging box and the items to be packaged are placed, the three-axis moving module drives the connecting arm, the horizontal mounting plate and the flat pressing plate to move, and presses the flat pressing plate tightly against the top of the item packaging box to restrict the foam glue inside the item packaging box, so that the foam glue fills the interior of the item packaging box and ensures that the top of the foam glue is flat.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The self-adaptive size packaging device and method for logistics packaging respectively transports the packaging box and the articles by setting two groups of conveying mechanisms. During the conveying process of the packaging box and the articles, the internal volume of the packaging box is detected by the packaging box detection mechanism, and the volume of the articles is detected by the article detection mechanism. The programmable controller can calculate the injection amount of the foam glue according to the detection data to ensure that the foam glue just fills the interior of the packaging box after expansion, so that the size of the foam glue after expansion is compatible with the packaging box and the articles, thereby achieving effective protection of the articles, avoiding the waste of foam glue, and avoiding the subsequent cutting of excess foam glue, thereby reducing the workload.

[0024] 2. The self-adaptive size packaging device and method for logistics packaging drives the connecting arm and the horizontal mounting plate to move through a three-axis moving module, drives the foam glue dispensing mechanism to move into the packaging box, injects the lower layer of foam glue into the packaging box, drives the clamping mechanism to move to clamp the items, puts the items into the packaging box, and then injects the upper layer of foam glue into the packaging box, thereby realizing automatic injection of foam glue and automatic placement and packaging of items, improving the degree of automation, and at the same time, after the foam glue is injected, by pressing a flat pressing plate on the top of the packaging box, the flatness of the top after the foam glue expands is ensured, which is convenient for subsequent packaging of the packaging box.

[0025] 3. The self-adaptive size packaging device and method for logistics packaging can drive the connection arm, the horizontal mounting plate and the adsorption mechanism to move through the three-axis moving module when injecting foam glue into the packaging box and placing articles. The separation membrane is adsorbed by the adsorption mechanism, and the separation membrane is placed between the upper and lower layers of foam glue and the articles to isolate the articles from the foam glue, thereby ensuring that the foam glue expands to effectively protect the articles and avoid adhesion between the articles and the foam glue, which is convenient for subsequent retrieval of the articles.
