Description

Technical Field

[0001] The conveying devices that feed the packaging machine all use the bottle bottom as the basis. The glass bottles are fed to the packaging machine, and the packaging is then packaged based on the bottle bottom. When producing glass bottles with special-shaped bottle bottoms, the conveying devices still use the bottle bottom as the basis for transportation. Since the bottle bottom is not flat and cannot stand, the packaging machine cannot be used for packaging, and manual packaging can only be used, resulting in low packaging efficiency. Background Art

DETAILED DESCRIPTION

[0022] The utility model will be further described below in conjunction with the accompanying drawings.

[0023] like Figure 1 As shown, the preferred embodiment of the U-turnable conveying device of the utility model comprises a conveying mechanism 1, a mounting frame 2, a rotating driver 3, a rotating shaft 4, a lifting driver 5 and a grabbing mechanism 6. The conveying mechanism 1 is used to convey glass bottles 7. The grabbing mechanism 6 is used to grab the glass bottles 7 located on the conveying mechanism 1, and the grabbing mechanism 6 is mounted on the lifting driver 5, and the lifting driver is used to drive the grabbing mechanism 6 to rise and fall. The rotating driver 3 is mounted on the mounting frame 2, the rotating shaft 4 is mounted on the rotating driver 3, and the lifting driver 5 is mounted on the rotating shaft 4; the rotating driver 3 is used to drive the rotating shaft 4 to reciprocate, for example, to stop after rotating 180° clockwise, and to reset by 180° counterclockwise when necessary, and of course, it can also rotate counterclockwise first and then clockwise; the rotating shaft 4 is used to transmit torque, that is, the rotating shaft 4 is used to drive the lifting driver 5, and when the lifting driver 5 receives the torque transmitted by the rotating shaft 4, the lifting driver 5 will also drive the grabbing mechanism 6 to rotate. The lifting drive 5 is a lifting cylinder, and of course in other embodiments, an oil cylinder can also be used; the rotation drive 3 is a stepping motor, and of course in other embodiments, a rotating cylinder can also be used.

[0024] When it is necessary to grab the glass bottle 7, the grabbing mechanism 6 grabs the glass bottle 7 on the conveying mechanism 1, and then the lifting driver 5 drives the grabbing mechanism 6 to rise and fall, and then the rotating driver 3 drives the rotating shaft 4 to rotate, the rotating shaft 4 rotates to drive the lifting driver 5 to rotate, the lifting driver 5 rotates to drive the grabbing mechanism 6 to rotate, and the grabbing mechanism 6 drives the glass bottle 7 to rotate 180°, thereby completing the U-turn of the bottle bottom and the bottle mouth. After the U-turn is completed, the lifting driver 5 is used to drive the grabbing mechanism 6 to descend, and the grabbing mechanism 6 puts the glass bottle 7 back to the conveying mechanism 1, completing the online U-turn of a glass bottle 7, and grabs the glass bottle 7 at the back position at the same time, that is, the U-turn process of the next glass bottle 7 is started again. In the next glass U-turn process, the rotating driver 3 rotates 180° in the opposite direction, and rotates back and forth in this way.

[0025] The mounting frame 2 includes two bases 21 installed on both sides of the transmission mechanism, two columns 22, a first connecting plate 23 and a second connecting plate 24. Each of the columns 22 is fixed on the corresponding base 21. The two ends of the first connecting plate 23 are respectively installed on the two columns 22. The second connecting plate 24 is fixed on the first connecting plate 23. The second connecting plate 24 is arranged along the width direction of the first connecting plate 23. One end of the second connecting plate 24 extends out of the first connecting plate 23, that is, the second connecting plate 24 and the first connecting plate 23 are arranged in a T shape. The rotary driver 3 is installed on the end of the second connecting plate 24 away from the first connecting plate 23, so that the grasping mechanism 6 can be kept away from the column 22, which is convenient for installation and debugging, and will not interfere with the column 22 during operation.

[0026] like Figures 1 to 3 As shown, a connecting block 231 is provided on the first connecting plate 23, and connecting blocks 231 are fixed on both sides of each end of the first connecting plate 23. The first connecting plate 23 is connected to the column 22 through the connecting block 231; positioning parts 232 are provided at both ends of the first connecting plate 23, and the positioning parts 232 are used to cooperate with the column 22.

[0027] The column 22 is provided with a slide groove 221 and a first positioning groove 222. There are two slide grooves 221, each of which is arranged in the vertical direction. A bolt 25 is arranged in the slide groove 221, and the bolt 25 can slide up and down in the slide groove 221. The head of the bolt 25 is located in the slide groove 221, and the screw rod of the bolt 25 extends out of the slide groove 221. The slide groove 221 is T-shaped, so that the slide groove 221 can limit the bolt 25 from being separated from the axial direction of the bolt 25. After the screw rod of the bolt 25 extends out of the slide groove 221, it passes through the connecting block 231 and is screwed with a nut 26 to fix the first connecting plate 23 on the column 22. When the height of the first connecting plate 23 needs to be adjusted, the nut 26 is loosened and then the height of the first connecting plate 23 is adjusted, and then the nut 26 is tightened. The position of the first connecting plate 23 can be adjusted according to the lifting drive 5 of different heights. The first positioning groove 222 is located between the two sliding grooves 221 , and the positioning portion 232 on the first connecting plate 23 extends into the positioning groove to guide the first connecting plate 23 to keep moving straight up and down when the height of the first connecting plate 23 is adjusted.

[0028] like Figure 1 and Figure 4 As shown, the gripping mechanism 6 includes a negative pressure suction nozzle 61 and a mounting plate 62. The mounting plate 62 is fixed to the lifting drive 5. The negative pressure suction nozzle 61 is fixed to the mounting plate 62. The negative pressure suction nozzle 61 is used to suck the glass bottle 7. There are two negative pressure suction nozzles 61 and two mounting plates 62. One negative pressure suction nozzle 61 is fixed to each mounting plate 62. With two negative pressure suction nozzles 61, when releasing one glass bottle 7, another glass bottle 7 can be gripped at the same time, without waiting for the suction nozzle to reset before gripping the glass bottle 7, thereby improving the efficiency of reversing.

[0029] In another embodiment, only one negative pressure suction nozzle 61 may be used. When the negative pressure suction nozzle 61 releases the glass bottle 7 after turning around, it is necessary to wait for the negative pressure suction nozzle 61 to reset and move the next glass bottle 7 to be turned around to the bottom of the negative pressure suction nozzle 61 before the turning process can be carried out.

[0030] When in use, the lifting drive 5 is used to drive the negative pressure suction nozzle 61 to move down to the position of picking up and placing the glass bottle 7, and then the negative pressure suction nozzle 61 located behind the conveying direction of the conveying mechanism 1 grabs the glass bottle 7. After the grabbing is completed, the lifting drive 5 drives the negative pressure suction nozzle 61 to move up. After the upward movement is completed, the transmission belt on the conveying mechanism 1 moves one station, and then the rotary drive 3 drives the negative pressure suction nozzle 61 to rotate and exchange the positions of the two negative pressure suction nozzles 61, and the suction nozzle previously located behind the conveying direction is rotated to the front of the conveying direction, and the suction nozzle originally located in the front of the conveying direction is rotated to the back of the conveying direction. In this way, the grabbed glass bottle 7 is aligned with the previous station, and the bottle mouth of the glass bottle 7 is turned around. Finally, the lifting drive 5 drives the negative pressure suction nozzle 61 to move down, and the glass bottle 7 is sent to the position of picking up and placing the glass bottle 7, and the rear negative pressure suction nozzle 61 releases the glass bottle 7. At this time, the other negative pressure suction nozzle 61 located behind the conveying direction also starts to grab the glass bottle 7, and so on. All the glass bottles 7 on the conveying mechanism 1 are turned around, and the turned glass bottles 7 can be packaged by a packaging machine with the bottle mouth as the packaging reference, replacing manual packaging, improving packaging efficiency, and reducing labor costs.

[0031] like Figure 5 As shown, in another embodiment, the lifting drive 5 is connected to the rotating shaft 4 through a fixing mechanism 8. The fixing mechanism 8 includes a flexible steel belt 81, a fixing plate 82 and a fixing column 83. The fixing plate 82 is fixed on the rotating shaft 4. One end of the flexible steel belt 81 is fixed on the fixing plate 82. The other end of the flexible steel belt 81 is connected to the fixing column 83 after passing around the lifting drive 5. The fixing column 83 is passed through the fixing plate 82 and is screwed with a nut 26 located on the side of the fixing plate 82 away from the lifting drive 5. In this way, the connection between the lifting drive 5 and the rotating shaft 4 is set to be detachable, which can facilitate the replacement of the lifting drive 5. The lifting drive 5 is provided with a second positioning groove 51, and the flexible steel belt 81 is fixed in the second positioning groove 51 to ensure that the flexible steel belt 81 does not slide and is fixed more stably.
