Description

Label gluing device

Technical Field

The invention relates to the technical field of labeling equipment, and in particular to a label gluing device.

Background technique

With the rapid development of mechanical automation technology, labeling has evolved from traditional manual pasting to today's automated technology. Most of the labels in the printing industry have self-adhesive backs, which are called self-adhesive labels. Since self-adhesive labels have the advantages of no need to apply glue, no paste, no water, no pollution, and save labeling time, they have a wide range of applications and are convenient and fast. Therefore, the corresponding existing automatic labeling machines are mostly used to automatically paste self-adhesive labels.

However, some labels are printed without glue, such as most beer labels and product certificates. Product certificates are usually printed with relevant information and then directly placed in the packaging box or pasted on the packaging. However, for occasions where labels need to be pasted on packaging boxes, there is a lack of such automatic label gluing and pasting equipment in the prior art, and the labels can only be manually glued and pasted, which is inefficient and labor-intensive.

Detailed ways

The specific implementation modes of the present invention are described below in conjunction with the accompanying drawings and examples. However, the following examples are only used to illustrate the present invention in detail and do not limit the scope of the present invention in any way.

The programs involved or relied upon in the following embodiments are all conventional programs or simple programs in the technical field, and those skilled in the art can make conventional selections or adaptive adjustments according to specific application scenarios.

Unless otherwise specified, the components, structures, mechanisms, sensors and other devices involved in the following embodiments are conventional commercially available products.

Please refer to FIG. 1 , in which the bottom flaps of the packaging box 100 are all in a folded state, and the upper flaps 101 , 102 , 103 , and 104 are all in an open state.

Embodiment 1: A label gluing and pasting device, see Figures 2 to 4, in which the arrows point to the conveying direction of the label, including a support panel 53, a paging mechanism, a gluing mechanism, a labeling mechanism corresponding to one side of the support panel 53, a label conveying mechanism that conveys the labels to the gluing mechanism and the labeling mechanism in sequence, and a control system, and the label conveying mechanism is arranged at the rear end of the paging mechanism.

The control system includes a control processor and an electric control reversing valve. The control processor uses a PLC, such as the transistor source type CP1E-N60DT1-A of Omron. For specific circuit connections, please refer to the instruction manual published on its official website. The vacuum pump, gas source and gas source processing equipment, electric control reversing valve and cylinder use commercial products, such as the corresponding products produced by Dawei Automation. The photoelectric sensor uses a commercial product. The electric control reversing valve is electrically connected to the control processor.

The paging mechanism includes a silo 11, a paging pressure plate 12 with an arc shape at the contact point with the label, a paging conveyor belt 13 corresponding to the bottom of the silo 11 and used to drive the label to move, and also includes a rubber plate that matches the shape of the paging pressure plate 12 and is arranged below the paging pressure plate 12. The rubber plate can increase the friction with the label, which is conducive to label paging. The bottom plate 14 of the silo 11 is inclined toward the outlet of the silo 11. The paging pressure plate 12 is arranged on the wall plate at the outlet of the silo 11, and the driving pulley 15 connected to the paging conveyor belt is corresponding to the bottom thereof. Since the bottom plate 14 is inclined toward the outlet of the silo 11, due to the conveying effect of the paging conveyor belt 13 and the tilting effect of the bottom plate 14, the stacked labels form an inclined surface protruding from the bottom and enter between the rotating driving pulley 15 and the paging pressure plate 12. The friction between the paging conveyor belt 13 and the label is greater than the friction between the labels, so that the label can be output in single pages.

The glue brushing mechanism includes a glue brushing wheel 21 for brushing glue, a glue groove 22 containing glue liquid arranged below the glue brushing wheel 21, and the bottom of the glue brushing wheel 21 is immersed in the glue liquid. The label conveying mechanism includes a plurality of label conveying belts 41, and a label driving belt 42 arranged above the glue brushing wheel 21 and the label conveying belt 41 and corresponding to the label conveying belt 41. The glue brushing wheel 21 is arranged at the gap between adjacent label conveying belts 41, which can brush glue without affecting the conveying of the label. When the label moves above the glue brushing wheel 21, the rolling glue brushing wheel 21 brushes glue on the label. The label conveying belt 41 is also used to raise the position of the label to prevent the glue liquid on the lower surface of the label from adhering to other objects. The viscosity of the glue liquid is relatively large. Through the setting of the label driving belt 42, the label can be smoothly moved under the joint action of the label conveying belt 41 below the label and the label driving belt 42 above the label. A first photoelectric sensor 43 is arranged at the front end of the conveying belt 41.

The labeling mechanism includes an adsorption element 31 for adsorbing labels and a movable element 32 for adjusting the position of the adsorption element. The adsorption element 31 is arranged at the tail of the conveyor belt 41, and the movable element 32 is arranged on the supporting panel 53. A second photoelectric sensor is arranged at the position corresponding to the adsorption element 31; the adsorption element 31 utilizes the third cylinder 310 to adsorb labels, and the movable element 32 includes a first rotating cylinder and a second rotating cylinder. The first rotating cylinder is arranged above the second rotating cylinder, and the first rotating cylinder is connected to the adsorption element 31 through an L-shaped connecting piece 33. The second rotating cylinder drives the first rotating cylinder to rotate 90 degrees clockwise in the horizontal plane, and the first rotating cylinder drives the L-shaped connecting piece 33 to rotate 90 degrees counterclockwise in the vertical plane to stick the label of the adsorption element 31 to the inner wall of the packaging box 100.

The control system is connected with the paging mechanism, the glue applying mechanism, the labeling mechanism, the label conveying mechanism, the first photoelectric sensor 43 and the second photoelectric sensor through a control loop.

The paging mechanism outputs one label from the hopper 11. When the label moves to the first photoelectric sensor position at the front end of the label conveyor belt, the paging conveyor belt stops, i.e., the label paging stops. During the label conveying process of the label conveyor belt, the glue brushing wheel first brushes the label and then conveys the label to the label removal position, i.e., under the adsorption element. The second photoelectric sensor is triggered, and the third cylinder 310 of the adsorption element is activated to absorb the label. After the vacuum is reached, the cylinder retreats, and then the first rotating cylinder and the second rotating cylinder are activated. After the second rotating cylinder is in place, the first rotating cylinder is activated to complete the labeling.

The U-shaped platform 52 and the mobile bracket 51 are connected to a screw with a handle to achieve precise control of the moving distance. The screw passes through the mobile bracket 51 and is rotatably connected to the U-shaped platform 52. The screw end with the handle end is rotatably connected to the side wall of the mobile bracket 51, and a fastener is provided between the handle and the side wall to prevent the screw from rotating. After the moving distance of the U-shaped platform 52 is adjusted, it is fixed by the fastener to prevent rotation. The lifting principle of the mobile bracket 51 is the same as the moving principle of the U-shaped platform 52, which will not be described in detail here.

A workbench 9 is provided under the movable bracket. The control system is connected to the supporting unit and the closing unit through a control loop.

The support unit includes a fourth cylinder 75 and a rotating shaft 71 perpendicular to the moving direction of the packaging box. The piston rod of the fourth cylinder 75 is connected to the rotating shaft 71 through a rocker 74. A baffle 72 is fixed on the rotating shaft 71 corresponding to the two corners of the packaging box, and a baffle 73 is fixed on the baffle 72 at a certain angle to the baffle 72. In order to adapt to packaging boxes 100 of different sizes, the fourth cylinder 75 and the rotating shaft 71 in the rear support unit are fixed on the U-shaped platform 52, and the fourth cylinder 75 and the rotating shaft 71 in the front support unit are fixed on the mobile bracket 51. After the packaging box 100 transported from the previous process enters the labeling station, the fourth cylinder 75 is activated, and the rotating shaft 71 rotates to drive the baffle 72 and the baffle 73 to move to the outside of the packaging box, thereby opening the swing cover of the packaging box 100, which can prevent the swing cover from buckling inward, making it convenient for labeling and the robot arm to put the product into the packaging box 100.

The closing unit includes a push plate 82 for pushing the flap parallel to the moving direction of the packaging box 100, and a push rod 81 for pushing the flap perpendicular to the moving direction of the packaging box. The push rod 81 is driven by the fifth rotary cylinder 83 to swing back and forth, and the push plate 82 is swung by the sixth cylinder. After the packaging box 100 is labeled and the product is placed, the fifth rotary cylinder 83 drives the push rod 81 to rotate to first close the flap 103 and the flap 102, and then the sixth cylinder is actuated to push the push plate 82 to close the flap 101 and the flap 104.

Two parallel slides 61 are provided on the workbench 6 along the moving direction of the packaging box 100. A transmission unit for moving the packaging box 100 to the next station is provided under the workbench. The transmission unit includes a base 91 that can be raised and lowered and moved.

A box pressing member 511 with an arc-shaped bottom is provided below the movable bracket 51 at the removal end of the packaging box 100. When the packaging box 100 passes under the box pressing member 511, the box pressing member 511 can further press the swing cover of the packaging box 100 to prevent the swing cover from tilting.

The present invention has been described in detail above with reference to the accompanying drawings and embodiments. However, those skilled in the art will appreciate that, without departing from the spirit of the present invention, the specific parameters in the above embodiments may be changed to form a plurality of specific embodiments, which are all within the common variation range of the present invention and will not be described in detail herein.
