Description

Technical Field

[0001] The utility model relates to the field of cold stretch hooding machines, in particular to a full-automatic product conveying device and a hooding system for the cold stretch hooding machines. Background Art

[0002] The cold stretch hooding machine refers to a special equipment that uses cold stretch film to automatically wrap and package goods stacked on pallets. The cold stretch hooding machine is often used for outer packaging wrapping when pallet packaging products are packed in pallets. Its working principle is: the film feeding equipment automatically extracts the film that is suitable for the height of the stacking pallet from a cold stretched film roll, and then cuts it after double-sided heat sealing on the top to form a bag. Then the film stretching device first collects the extracted film roll, and then stretches the film from the four top corners of the stacking pallet at the same time, and bags it from top to bottom. Relying on the characteristics of the cold stretch film itself, the film is shrunk back to the stack shape to form a five-sided waterproof, moisture-proof, and stable stack shape package.

[0003] Before the pallet cargo is covered with film, dust, mosquitoes and other impurities on its surface must be cleaned to ensure that the surface of the cargo inside the film is clean. The existing method is to manually use compressed air to blow dust off the surface of the cargo, and then use a forklift to move the dust-free cargo to the film covering machine. According to the height of the pallet cargo (manual measurement), the height data is input into the height parameter of the film covering machine. The film covering machine extracts the film suitable for the height of the stacked pallet according to the set parameters and performs the film covering operation. There are the following disadvantages.

[0004] Manual dust removal is inefficient and labor-intensive. Due to different products or loading requirements, the height of cargo stacks is inconsistent. Before each pallet of product is filmed, the height must be manually measured and input into the film machine. The work efficiency is relatively low and the labor intensity is high. When the pallet cargo is transported to the film machine by a forklift, the pallet and the film machine need to be positioned and matched to ensure that the filming operation can accurately cover the cargo. The existing method is often to install a fixed position on the base of the film machine, and manually adjust the forklift to match the pallet cargo with the film machine base position. Because of its fixed position, it can only match pallet cargo of a single size. Commonly used pallet sizes on the market include products of different widths such as 1m-1.3m. When different products use pallets of different specifications, the position needs to be manually adjusted to adapt to pallets of different specifications. The forklift adjustment process is inefficient. In addition, the manual adjustment process is prone to collisions between cargo and equipment due to improper operation, resulting in safety problems.

[0047] The fully automatic product conveying device 10 for the cold stretch hood film machine also includes a fan 700, which is connected to the multiple air knives 510 of the gantry 500, and is used to blow air to the air knives 510, and blow it out to the middle position of the gantry 500 through the air outlet 520, that is, it can be blown to the stacked goods conveyed through the gantry 500, so as to achieve air blowing and dust removal of the stacked goods. The dust removal is completed during the conveying process of the stacked goods, and then enters the film coating machine to prevent dust from adhering to the film coating and affecting the film coating effect.

[0048] Specifically, an infrared proximity switch 400 is also fixed on the gantry 500, and the infrared proximity switch 400 is used to sense and start the fan 700 to achieve full-automatic removal of mosquitoes and dust from the goods.

[0049] Specifically, the gantry 500 includes an air inlet pipe 600 and a blowing pipe 610. The air inlet pipe 600 has a U-shaped structure, and the blowing pipe 610 also has a U-shaped structure. The blowing pipe 610 is located on the inner side of the air inlet pipe 600. One end of the air inlet pipe 600 is connected to the fan 700, and the other end of the air inlet pipe 600 is connected to the blowing pipe 610.

The first wind blade 510 and the second wind blade 510 are fixed on two opposite sides of the gantry 500, and the air outlets 520 of the first wind blade 510 and the second wind blade 510 extend in the vertical direction. The third wind blade 510 is fixed on the top of the gantry 500, and the air outlet 520 of the third wind blade 510 extends in the horizontal direction.

[0051] The gantry 500 is in a "U" shape, and the first wind knife 510, the second wind knife 510 and the third wind knife 510 are also arranged in a "U" shape and fixed on the left and right sides and the top of the gantry 500 to blow the stacked goods conveyed through the gantry 500 from both sides and the top. The blade is strip-shaped, which increases the blowing area and improves the dust removal effect during the movement of the stacked goods.

[0052] Reference Figure 1 , Figure 2 and Figure 3 In this embodiment, the fully automatic product conveying device 10 for the cold stretch hood machine also includes an infrared rangefinder 530, which is fixed to the top of the gantry 500. The infrared rangefinder 530 is used to detect the distance from the top of the stacked goods to the top of the gantry 500.

[0053] The infrared rangefinder 530 is arranged above the stacked goods. The height of the stacked goods can be calculated according to the measured height, and the data is sent to the main control module of the film covering machine to realize fully automatic measurement of the film covering.

[0054] An embodiment of the utility model also provides a hood system, which includes a hood machine and a fully automatic product conveying device 10 for the cold stretch hood machine. The fully automatic product conveying device 10 for the cold stretch hood machine is arranged upstream of the hood machine, and the fully automatic product conveying device 10 for the cold stretch hood machine is used to convey stacked goods to the hood machine.

[0055] The centrally stacked goods are transported to the coating machine for coating. During the transportation process, air blowing and dust removal can be carried out and the height of the stacked goods can be measured to achieve fully automatic coating without manual measurement, thereby improving efficiency and construction safety.

[0056] According to a fully automatic product conveying device 10 for a cold stretch hood machine provided in this embodiment, the working principle of the fully automatic product conveying device 10 for a cold stretch hood machine is: the fully automatic product conveying device 10 for a cold stretch hood machine is spliced ​​with the hood machine, and its function is to realize automatic dust blowing on the surface of pallet goods, match full-size pallet goods with the hood machine for centering, automatically measure the height of the goods and feed back the data to the hood machine.

[0057] The motor 310 at the bottom of the conveying platform 100 serves as a power source. The motor 310 is connected to the screw rod 320. The first thread segment at both ends of the screw rod 320 has a left-handed thread direction at one end and a right-handed thread segment at the second thread segment. When the motor 310 rotates, it drives the screw rod 320 to rotate, driving the two baffles 200 to move laterally in opposite directions. Because the thread directions at both ends of the screw rod 320 are different, when the screw rod 320 rotates, the two baffles 200 move closer to the middle or away from both sides at the same time, driving the two baffles to move toward the middle to push the goods. A proximity switch 400 is installed on each of the two baffles. The proximity parameter is set according to the distance between the proximity switch 400 and the baffle. When the baffle pushes the goods, the proximity switches 400 on both sides stop pushing when they are sensed.

[0058] A gantry 500 is installed above the conveying platform 100, and wind knives 510 are installed on the left and right support beams and the upper beam of the gantry 500. An infrared proximity switch 400 is installed on the top, and a high-power fan 700 is used as a power source. When the infrared proximity switch 400 senses the goods, the fan 700 is automatically started, and the powered wind is blown out from the wind knife 510 to blow away the dust and mosquitoes on the surface of the goods.

[0059] An infrared rangefinder 530 is installed above the gantry 500. When the goods pass through the gantry 500, the height between the top and the gantry 500 is automatically measured. After calculation and conversion by the PLC program, the height of the goods is measured and the height data is fed back to the film covering machine to achieve automatic distance measurement and extract the corresponding length of stretch film. If the height of the gantry 500 is L1, the infrared measurement shows that the top of the goods is L2 higher than the gantry 500, and the fixed film covering margin L3 is added, then the data L4=L1-L2+L3 is fed back to the film covering machine, and L1 and L3 are fixed values.

[0060] The fully automatic product conveying device 10 for a cold stretch hooding machine provided in this embodiment has at least the following advantages:

[0061] The two baffles 200 on the conveying platform 100 are driven by the driving mechanism 300 to synchronously approach and move away from each other, driving the stacked goods to be in a central position, thereby automatically aligning the pallet stacked goods with the sleeve machine, eliminating the need for manual adjustment, and being adaptable to full-size wide pallets and unconventional wide pallets, greatly improving work efficiency and avoiding safety hazards caused by complex operations during manual adjustment.

[0062] Proximity switches 400 are installed on the baffles on both sides. When the two proximity switches 400 sense at the same time, the motor 310 stops moving and returns, which can match the full-size pallet for deviation correction and centering.

[0063] The air knife 510 replaces manual mosquito and dust removal, reduces the number of pre-filming operations, improves work efficiency, and has a better dust removal effect than manual dust removal. There are no dead corners for cleaning, and the intensity of manual work is reduced. After dust removal, the air knife 510 directly enters the film covering machine for film covering operations, avoiding secondary pollution to the surface of the goods caused by subsequent operations after manual dust removal.

[0064] The infrared rangefinder 530 automatically measures distance and transmits data to replace manual measurement input, which improves work efficiency and reduces manual work intensity. The measurement data is more accurate, and the film covering machine can extract the film with the optimal matching length for film covering operation. The packaging of pallet goods can be more beautiful, and the moisture-proof and dust-proof effects are more ideal. It can also reduce the waste of film materials caused by certain deviations in manually set parameters.

[0065] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
