Adhesive labeling machine product orientation device
Technical field
The present invention relates to labeling device technical field, a kind of product orientation used on especially special labeling device is filled
It sets.
Background technique
For adhesive sticker because of good characteristics such as its firm pasting, water-proof skid-proof, pattern finenesses, application is very extensive, can be applied to
In the mark of the products such as food, beverage, daily use chemicals, medicine, logistics.In order to improve working efficiency, production enterprise is adopted mostly at present
Carry out the stickup of adhesive sticker on the surface of product with adhesive labeling machine, bonding method be in product line transmission process into
Mobile state labels or by being labelled after sucker suction label by cylinder moving;No matter labelled using which kind of form,
It requires to position product in poster process, just can guarantee the qualification rate of labeling position.
In adhesive labeling machine poster process, for convenient for fixed plane class product, labeling is comparatively easy,
Product conveyor can be directlyed adopt as carrier push label-sticking mechanism downwards can be completed, and for irregular or circle class
For product in paste process, the positioning of product just becomes more intractable.In addition, currently in order to reaching the mesh of full automatic high efficiency production
, adhesive labeling machine also gradually adopts rotating disc type to design, i.e., product is conveyed by turntable, and will during conveying
Label is attached on product.Since product rotates in turntable, so that the direction of product constantly changes, how could be correct
To apply labels to be that labelling machine needs one of the technological difficulties that solve on product.
Summary of the invention
The technical problem to be solved by the invention is to provide a kind of product orientation device applied on adhesive labeling machine,
The labeling requirement that can satisfy various shape product improves the labeling qualification rate of product.
In order to solve the above technical problems, the technical solution used in the present invention is as follows.
Adhesive labeling machine product orientation device, including the laser scanning for acquiring shape of product structure to be labelled
Instrument treats the adjusting positioning mechanism that labeling product is positioned and the PLC controller for controlling to adjust positioning mechanism movement,
The laser scanner and adjusting positioning mechanism are arranged at the other side of the product conveyor relative to labelling machine label-sticking mechanism, swash
The input terminal of the output end connection PLC controller of photoscanner, the output end connection of PLC controller adjust the controlled of positioning mechanism
End.
Above-mentioned adhesive labeling machine product orientation device, the adjusting positioning mechanism include hold out against cylinder, mounting plate with
And fixed setting, on a mounting board and towards the shape adjustment component that conveyer belt is arranged, the shape adjustment component includes several groups
Shape adjustment cylinder, the piston-rod end of shape adjustment cylinder are adjacent to the patch of product surface to be labelled by attachment base hinged one
Block;It is described to hold out against cylinder and the controlled end of each shape adjustment cylinder is connect with the output end of PLC controller respectively.
Above-mentioned adhesive labeling machine product orientation device, the attachment base are Horizontal U-shaped structure, and paste block passes through connecting column
It is hinged in U-shaped attachment base, paste block can be in U-shaped attachment base perpendicular to attachment base Plane Rotation.
Above-mentioned adhesive labeling machine product orientation device, the paste block are flat structure, are contacted with product to be labelled
End face on be provided with non-skid film.
Due to using above technical scheme, the invention technological progress is as follows.
The present invention can be equipped with as individual components with any labelling machine, and when use is directly installed on labelling machine labeling
The right opposite of mechanism, it is very convenient.Each shape adjustment cylinder is all independently controlled by PLC controller on mounting plate in the present invention
System, the product structure shape that PLC controller can be acquired according to laser scanner control each shape adjustment cylinder movement, thus make with
The opposite face of the paste block and product position to be labelled that adjust cylinder end is in close contact, and product is stablized in labeling position, is labelling machine
The thrust generated in structure poster process provides support, further increases the labeling qualification rate of product.Due to each shape adjustment cylinder
By PLC controller independent control, therefore the labeling positioning that can meet various shape product uses, versatile.

Specific embodiment
Below in conjunction with specific embodiment, the present invention will be described in further detail.
A kind of adhesive labeling machine product orientation device is arranged in product conveyor 1 relative to labelling machine label-sticking mechanism 2
The other side, structure as shown in Figure 1, include laser scanner 3, PLC controller 4 and adjust positioning mechanism;Laser scanner
Output end connection PLC controller 4 input terminal, for the shape and structure of product to be labelled of acquisition to be conveyed to PLC control
Device 4;The output end connection of PLC controller 4 adjusts the controlled end of positioning mechanism, and PLC controller 4 is according to laser scanner scans
Shape of product control and regulation positioning mechanism is treated labeling product and is positioned.
The feed side of conveyer belt is arranged in laser scanner 3, for acquire conveyed on conveyer belt with the outer of labeling product
ZLDS200 laser scanner can be used in portion's shape, obtains shape of product using non-contact scanning, is not required to shut down.
Adjusting positioning mechanism includes holding out against cylinder 5, the shape adjustment group of mounting plate 6 and fixed setting on a mounting board
Part, shape adjustment component is arranged towards conveyer belt, including several groups shape adjustment cylinder 7, the piston rod end of shape adjustment cylinder
End is adjacent to the paste block 8 of product surface to be labelled by attachment base hinged one;It is above-mentioned hold out against cylinder and each shape adjustment cylinder by
Control end is connect with the output end of PLC controller respectively.
Attachment base in the present invention is Horizontal U-shaped structure, and paste block is hinged in U-shaped attachment base by connecting column, can be U-shaped
Perpendicular to attachment base Plane Rotation in attachment base.For the positioning requirements for meeting different shape product, paste block direction product to be labelled
End face be flat structure, be provided with non-skid film on the end face contacted with product to be labelled, be firmly supported with facilitating wait paste
Mark product.
The present invention at work, when walking on the conveyor belt wait label product, first passes around laser scanner and is scanned,
The result of scanning is conveyed to PLC controller by laser scanner, and PLC controller obtains shape of product structure, is then calculated
The distance of each shape adjustment cylinder distance product to be labelled makes shape to control each shape adjustment cylinder movement at labeling position
It adjusts component and forms linear structure corresponding with product institute position location to be labelled, then control holds out against cylinder and stretches out shape tune
Section component is adjacent in the position location of product to be labelled;Hereafter label-sticking mechanism can carry out labelling operation.
