Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of beverage bottle labeling, in particular to a glass beverage bottle labeling device based on a robot. BACKGROUND

[0002] The glass bottle labeling machine realizes accurate positioning and fitting of labels through the cooperative movement of the drive wheel, the labeling wheel and the reel, combined with sensor detection and PLC control. The drive wheel intermittently drags the label strip, the label strip is pulled out from the reel, and the label is separated from the backing paper through the label stripping plate (label knife). When the glass bottle reaches the specified position through the conveyor belt, the label strip drive wheel accelerates to match the speed of the conveyor belt, the labeling wheel presses the label on the bottle, and then slows down and stops. The extension speed and length of the label during labeling of the glass beverage bottle can be adjusted through the control panel. The glass beverage bottle is generally clamped and fed by a robot during feeding, and placed on the conveyor belt for labeling.

[0003] When labeling the glass beverage bottle in the prior art, the label backing paper passes through the label knife, and the label is automatically stripped by the winding assembly. When the infrared sensor detects that the glass beverage bottle passes, the control equipment pushes the compression roller to realize contact between the glass beverage bottle and the label, and the rotating roller rotates to realize rotary labeling. Since the backing paper and the rotating roller will rotate and stop rotating, the label knife will be slightly offset after a long time. When the label knife is offset, the backing paper will move up and down on the side of the label knife, and the label will be inclined on the glass bottle during labeling, affecting the accuracy of labeling. In addition, the label knife is fixed to the bottom plate by two adjustable screws, and the levelness of the label knife needs to be adjusted repeatedly by adjusting the two screws, which is not convenient for quickly adjusting the levelness of the label knife. In addition, no component is arranged on the label knife to monitor the label, and workers can only observe the label on the glass bottle to understand whether the label is offset. No offset alarm component is arranged, which is not convenient for timely detection of label offset for maintenance, resulting in the need for rework and cleaning of the labeled glass bottle, wasting time and reducing the labeling qualification rate. When installing the backing paper, the end of the backing paper needs to be clamped with the winding roller. In the prior art, the backing paper is generally fixed by a U-shaped elastic clamp when clamping the backing paper, and the clamp is not convenient to move and insert into the clamping groove on the side of the winding roller, which is not convenient to operate.

DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in conjunction with specific embodiments.

An installation plate 404 is mounted on the bottom of the side frame 301 and located at the bottom of the movable opening 402. An installation frame 405 is fixedly connected to the bottom of the installation plate 404. A bottom plate 406 is fixedly connected to the bottom of the installation frame 405. Two wedge-shaped blocks 408 are fixedly connected to the bottom plate 406 in a symmetrical manner. A trapezoidal block 409 is slidably connected to the bottom plate 406 and located between the two wedge-shaped blocks 408. A lead screw 411 is horizontally and threadedly connected to one of the wedge-shaped blocks 408. The lead screw 411 is rotatably connected to the trapezoidal block 409. Rolling balls 410 are arranged between the two wedge-shaped blocks 408 and the two sides of the trapezoidal block 409. Two push rods 407 are rotatably connected to the installation plate 404 in a symmetrical manner about the rotating seat 403. The bottom of each push rod 407 is rollingly connected to a rolling ball 410. The bottom of each push rod 407 abuts against the bottom of the marking cutter 401. The height of the trapezoidal block 409 is equal to the height of the two wedge-shaped blocks 408. The side surface of the trapezoidal block 409 and the two wedge-shaped blocks 408 form a V-shaped structure. One end of the marking cutter 401 is inclined. The other end of the marking cutter 401 is in a rectangular structure. The rotating seat 403 is located at the center of the rectangular surface at the bottom of the marking cutter 401. The adjusting mechanism 4 further comprises two groups of baffles 412 mounted on the bottom plate 406 in a symmetrical manner about the centers of the two rolling balls 410. The length of each baffle 412 is greater than the distance between the wedge-shaped block 408 and the trapezoidal block 409. The guide mechanism 3 further comprises a placement disc 302 rotatably connected to the side frame 301. The side frame 301 rotatably connects a guide column one 303 and a guide column two 304. A fixed frame 305 in an inverted L-shaped structure is mounted on the side frame 301. A motor two 307 is mounted on the fixed frame 305. A drive shaft 306 is connected to the output end of the motor two 307 through a coupling. The conveying mechanism 2 comprises a track 201 mounted on the support 1. Two rolling shafts 204 are rotatably connected to the track 201 in a symmetrical manner. A conveying belt 203 is mounted on the two rolling shafts 204. A motor one 202 is mounted on the track 201. The output end of the motor one 202 is fixedly connected to one of the rolling shafts 204 through a coupling. The marking cutter 401 and the drive shaft 306 are located on the inner side of the track 201. A robot body 205 is mounted on the support 1.The pressing mechanism 6 comprises a support frame 601, the support frame 601 is fixedly connected between the track 201 and the support frame 1, two air cylinders 602 opposite to the driving shaft 306 are installed on the support frame 601, a fixed frame 603 in a V-shaped structure is fixedly connected to the extension end of the two air cylinders 602, a pressing roller 604 is vertically rotatably connected to the two fixed frames 603, and the driving shaft 306 and the two pressing rollers 604 are distributed in a triangular shape.

[0035] When labeling the outer side of the glass beverage bottle, the back paper with the label is placed on the placing disc 302. Since the placing disc 302 is rotationally connected with the side frame 301, automatic feeding can be realized, the back paper is pulled to be wound on the guide column one 303 and the guide column two 304, further passes between the label cutter 401 and the driving shaft 306, then the back paper passes the other side of the label cutter 401 and rolls with the guide column three 502, and finally the end of the back paper is fixed on the reel 504. The glass beverage bottle is fed to the conveying belt 203 by the robot body 205, the motor one 202 is started to realize the rotation of the conveying belt 203 driven by the roller 204, and the glass bottle is conveyed. When the infrared sensor installed on the track 201 detects that the glass bottle reaches, the motor two 307 is started to drive the driving shaft 306 to rotate, and the rotation of the reel 504 drives the back paper to move a distance. The label is peeled off by the label cutter 401. When the glass bottle reaches the driving shaft 306, the control equipment controls the cylinder 602 to extend, and then the two compression rollers 604 clamp the glass bottle. The label is clamped between the glass bottle and the driving shaft 306. After the motor two 307 rotates for a certain number of turns, the glass bottle is rotated, the compression roller 604 is rotated, and the labeling is completed. If the label cutter 401 is tilted due to the shaking of the driving shaft 306 caused by the unevenness of the overall structure or the one-stop-one-rotation of the driving shaft 306, which causes the label on the back paper to be attached obliquely, the screw rod 411 horizontally connected with the rotating wedge block 408 can be rotated. Since the screw rod 411 is rotationally connected with the trapezoidal block 409, rotating the screw rod 411 can drive the trapezoidal block 409 to slide between the two wedge blocks 408. The height of the trapezoidal block 409 is equal to the height of the two wedge blocks 408, and the side surface thereof forms an inverted V-shaped structure with the two wedge blocks 408. During the sliding process, the rolling balls 410 between the two sides of the trapezoidal block 409 and the two wedge blocks 408 roll, reducing the friction force and making the adjustment process smoother. The two push rods 407 are symmetrically rotationally connected with the rotating seat 403 on the mounting plate 404. The bottom of the push rod 407 is rolling connected with the rolling ball 410 and abuts against the bottom of the label cutter 401. When the position of the trapezoidal block 409 changes, the positions of the rolling balls 410 change, one rolling to the left and the other rolling to the right, thereby driving one of the push rods 407 to rise and the other to lower. The distance between one side of the trapezoidal block 409 and the wedge block 408 becomes smaller, and the distance between the other side of the trapezoidal block 409 and the other wedge block 408 becomes larger. Since the bottom of the push rod 407 abuts against the bottom of the label cutter 401, the two push rods 407 rise and lower, thereby adjusting the levelness of the label cutter 401. One end of the label cutter 401 is arranged obliquely, and the other end is in a rectangular structure. The rotating seat 403 is located at the center of the rectangular surface at the bottom of the label cutter 401. This structure design ensures the stability and accuracy of the levelness adjustment of the label cutter 401, avoids small deviations in the conveying process of the back paper from causing the label to be attached obliquely, and is simple and fast to operate.
