Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a feeding device of a labeling machine for automatically conveying packaging bags. Background Art

[0002] In the product packaging and processing production line, pasting sticker labels is a common process. This process is usually carried out by a robot to grab the labels and paste them. In order to facilitate the robot to grab, the stickers need to be neatly stacked and promptly loaded into the robot's grabbing station.

[0003] During the feeding process, the packing bags are mainly transported by conveyor belts. However, the spacing between the packing bags is generally difficult to control during the transportation process. Moreover, if the packing bags cannot be fixed well during transportation, the labels on the packing bags may be misaligned during labeling. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the utility model provides a feeding device for a labeling machine that automatically conveys packaging bags, so as to solve the problem mentioned in the above background technology that the packaging bags are mainly conveyed by a conveyor belt during the feeding process, but the spacing between the packaging bags is generally difficult to control during the transportation process, and if the packaging bags cannot be well fixed during transportation, then the packaging bags may be misplaced when being labeled.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding device of a labeling machine for automatically conveying packaging bags, comprising a base frame, four supporting legs fixedly installed at the bottom of the base frame, the four supporting legs are arranged in a rectangular array at the bottom of the base frame, a conveyor belt is arranged on the base frame, a mounting plate is fixedly installed at a position closer to the front end of one side end face of the base frame, a driving motor is fixedly installed on the mounting plate, the output end of the driving motor is connected to the conveyor belt, a plurality of groups of fixing frames in a linear array are arranged on the conveyor belt, a magnetic block is fixedly installed in the fixing frame, and a fixing platform is arranged inside the fixing frame.

[0006] By adopting the above technical solution, the structure on the base frame is supported by the four supporting legs installed at the bottom of the base frame. Then, when the packaging bags need to be transported, the staff turns on the driving motor through the controller, so that the driving motor drives the conveyor belt in the base frame to move, so that the conveyor belt drives the packaging bags to be transported forward. Then, the staff can remove the fixed platform from the fixed frame through the protruding blocks installed on both sides of the fixed platform. After the fixed platform is removed, the staff can place the packaging bag on the electrostatic suction cup, so that the electrostatic suction cup can adsorb the packaging bag.

[0007] Preferably, a mounting block is fixedly installed at the bottom of the fixing table, a magnetic suction groove is opened at the bottom of the mounting block, raised blocks are fixedly installed on both sides of the top of the fixing table, and an electrostatic suction cup is provided at the top of the fixing table.

[0008] By adopting the above technical solution, the fixing platform is removed from the fixing frame by using the protruding blocks installed on both sides of the fixing platform, and then the mounting frame at the bottom of the fixing platform is aligned with the fixing frame, so that the magnetic blocks in the fixing frame are attracted to the magnetic grooves opened in the mounting frame, thereby fixing the fixing platform in the fixing frame.

[0009] Preferably, the two vertical plates fixedly mounted on the base frame have infrared sensors fixedly mounted on the inner end surfaces of the two vertical plates, and a controller fixedly mounted on one end surface of the vertical plates.

[0010] By adopting the above technical solution, after the packaging bag is moved to the bottom of the glue injection head by the conveyor belt, the fixed frame will block the infrared sensors installed at the inner ends of the two vertical plates, so that they cannot receive the signals sent. Then the controller will send signals to both the glue injection head and the drive motor to open the solenoid valves thereon and also stop the drive motor from driving the conveyor belt, so as to inject glue onto the packaging bag directly below it.

[0011] Preferably, a glue storage tank is fixedly installed on the top of the vertical plate, and two glue injection heads are fixedly installed on the bottom of the glue storage tank. Solenoid valves are provided in the two glue injection heads, and the glue injection heads are both arranged directly above the fixed frame.

[0012] By adopting the above technical solution, the glue storage tank provided at the top of the vertical plate can better store the glue, and then the packaging bag can be injected with glue through the two glue injection heads installed at the bottom of the glue storage tank.

[0013] Preferably, the fixing platform and the fixing frame are fixed together by means of a magnetic groove provided on the bottom of the fixing platform and a magnetic block provided in the fixing frame.

[0014] By adopting the above technical solution, the mounting bracket at the bottom of the fixing platform is aligned with the fixing bracket, so that the magnetic blocks in the fixing bracket are attracted to the magnetic grooves in the mounting bracket, thereby fixing the fixing platform in the fixing bracket.

Then, when the electrostatic suction cup adsorbs the packing bags, the staff aligns the mounting frame at the bottom of the fixed platform with the fixed frame, so that the magnetic blocks in the fixed frame adsorb with the magnetic grooves in the mounting frame, so that the fixed platform is fixed to the fixed frame, so that the staff can better position the packing bags, thereby better preventing misalignment during labeling and better controlling the distance between the packing bags.

[0017] 2. The feeding device of the labeling machine that automatically conveys the packaging bags sends signals to the glue injection head and the drive motor to open the solenoid valve on them and also stop the drive motor from driving the conveyor belt to inject glue onto the packaging bags directly below. After the glue injection of the packaging bags is completed, the controller closes the solenoid valve on the glue injection head and then turns on the drive motor, so that the conveyor belt drives the glue-coated packaging bags to be transported forward, making it easier to label them.

A conveyor belt 3 is provided on the base frame 1, and a mounting plate 4 is fixedly installed at a position closer to the front end of one side of the base frame 1. A drive motor 5 is fixedly installed on the mounting plate 4. The output end of the drive motor 5 is connected to the conveyor belt 3, and the conveyor belt 3 is provided with multiple groups of linear arrays. The fixing frame 6 has a magnetic block 7 fixedly installed in the fixing frame 6, a fixing platform 8 is provided inside the fixing frame 6, a mounting block 9 is fixedly installed at the bottom of the fixing platform 8, a magnetic groove 10 is provided at the bottom of the mounting block 9, and a raised block 11 is fixedly installed on both sides of the top of the fixing platform 8. An electrostatic suction cup 12 is provided at the top of the fixing platform 8, and the fixing platform 8 and the fixing frame 6 are fixed by the magnetic groove 10 provided at the bottom and the magnetic block 7 provided in the fixing frame 6.

[0026] Working principle: The structure on the base frame 1 can be supported by the four supporting legs 2 installed at the bottom of the base frame 1. Then, when the packaging bags need to be transported, the staff will turn on the driving motor 5 through the controller 15, so that the driving motor 5 drives the conveyor belt 3 in the base frame 1 to move, so that the conveyor belt 3 drives the packaging bags to be transported forward. Then, because there is a magnetic block 7 in the fixed frame 6, and the magnetic block 7 can be well connected with the magnetic groove 10 opened in the mounting block 9, the staff can remove the fixed platform 8 from the fixed frame 6 through the protruding blocks 11 installed on both sides of the fixed platform 8. Then, when After the fixing table 8 is disassembled, the staff can place the packaging bag on the electrostatic suction cup 12, so that the electrostatic suction cup 12 can adsorb the packaging bag. Then, when the electrostatic suction cup 12 has completed adsorbing the packaging bag, the staff aligns the mounting frame at the bottom of the fixing table 8 with the fixing frame 6, so that the magnetic block 7 in the fixing frame 6 and the magnetic suction groove 10 opened in the mounting frame are adsorbed with each other, so that the fixing table 8 is fixed to the fixing frame 6, so that the staff can better position the packaging bag, thereby better preventing misalignment during labeling and better controlling the distance between the packaging bags.

[0027] Example 2:

[0028] Please refer to Figures 1-4, which show a feeding device for a labeling machine that automatically conveys packaging bags. The output end of the drive motor 5 is connected to the conveyor belt 3. The conveyor belt 3 is provided with multiple groups of fixed frames 6 in a linear array. The top of the fixed platform 8 is provided with an electrostatic suction cup 12. Two vertical plates 13 are fixedly installed on the base frame 1.

Solenoid valves are provided in the two glue injection heads 17. The glue injection heads 17 are both arranged directly above the fixed frame 6.

[0029] Working principle: The conveyor belt 3 connected to its output end is driven by the driving motor 5 to move, so that the conveyor belt 3 drives the fixed frame 6 on it to move, and then the electrostatic suction cup 12 of the fixed platform 8 can better adsorb the packaging bag, so as to facilitate the gluing of the packaging bag. Then, when the conveyor belt 3 drives the packaging bag to move directly below the glue injection head 17, the fixed frame 6 will block the infrared sensor 14 installed at the inner end of the two vertical plates 13, so that it cannot receive the signal sent. Then the controller 15 will send a signal to both the glue injection head 17 and the driving motor 5 to open the solenoid valve thereon and also make the driving motor 5 stop driving the conveyor belt 3, so as to inject glue onto the packaging bag directly below it. Then, when the glue injection of the packaging bag is completed, the controller 15 will close the solenoid valve on the glue injection head 17 and then turn on the driving motor 5, so that the conveyor belt 3 drives the glued packaging bag to be transported forward, so as to facilitate labeling thereof.
