The bottom labeling device 240 includes an unwind mechanism 241, a tensioning mechanism 242, a steering mechanism 243, a label peeling mechanism 244, a labeling drive mechanism 245, and a rewind mechanism 246.
The unwinding mechanism 241 includes an unwinding reel 2411 for placing a roll of self-adhesive labels, and an unwinding drum 2412 for unwinding the roll of self-adhesive labels. The self-adhesive label roll comprises a bottom tape and a plurality of self-adhesive labels attached to the bottom tape.
The tensioning mechanism 242 includes a tensioning roller 2421, an extension arm rotatably coupled to the tensioning roller 2421 and the unwind reel 2411, respectively, and a spring (not shown due to structural shielding) coupled between the extension arm and the unwind reel 2411.
The steering mechanism 243 includes a plurality of steering rollers 2431 for steering and conveying the unwound self-adhesive label tape and assisting in tensioning the unwound self-adhesive label tape. The unwound self-adhesive label tape is wound around the multi-turn roller 2431 and the tension roller 2421, and the tension roller 2421 tensions the self-adhesive label tape wound thereon toward the lower left in the drawing by the spring.
The labeling driving mechanism 245 includes a labeling driving motor 2451 and a driving roller 2452, and the driving roller 2452 rotates in a predetermined direction under the driving of the labeling driving motor 2451 to drive the self-adhesive label tape wound on the other rollers to rotate.

The surface direction of the peeled self-adhesive label is basically consistent with the surface direction of the upper surface of the peeling plate 2441, an inclined included angle is formed between the surface direction of the peeled self-adhesive label and the surface direction of the bottle bottom 113 to be labeled above the self-adhesive label according to the angle setting of the peeling plate 2441, and the adhesive surface of the peeled self-adhesive label is upwards positioned on the moving path of the bottle bottom 113. Thus, the inclined self-adhesive label is attached to the bottom 113 in a proper manner during the movement of the bottom 113 in the horizontal direction.
In addition, a label sensor is provided at the end of the release plate 2441, which senses a self-adhesive label and generates a corresponding signal upon release of the self-adhesive label from the base tape at the end, and the bottom labeling device 240 can control the speed of unwinding the labels based on the signal.
As shown in fig. 5, the heat shrink labeling device 250 is disposed beside the second conveying device 220, and is used for heat shrink labeling the bottle body 110 with the bottom labeled on the second conveying device 220. The heat shrink sleeve device 250 comprises a sleeve mechanism 251, a circumferential heating mechanism (not shown), a clamping mechanism 253, and a bottom heating mechanism 254.
Wherein, the sleeve mechanism 251 is used for sleeving the film-shaped heat-shrinkable label rolled into a tube shape on the outer circumference of the bottle body 110. The circumferential heating mechanism is used for circumferentially heating the heat-shrinkable label, so that the heat-shrinkable label is circumferentially heat-shrunk and coated on the bottle body 113. The clamping mechanism 253 is similar to the clamping device 230, and is used for clamping the bottle body 110 coated with the heat-shrinkable label, so that the self-adhesive label 130 attached to the bottle bottom 113 is exposed. The bottom heating mechanism 254 is used for heating the heat-shrinkable label portion around the bottle bottom 113 of the clamped bottle body 110, so that the heat-shrinkable label portion shrinks towards the middle of the bottle bottom 113, and the heat-shrinkable label portion wraps the edge portion of the self-adhesive label 130, so as to form the heat-shrinkable label 140.
The specific structure of the heat shrink sleeve label device 250 may be a structure in the prior art, and will not be repeated.
Thus, in step S3, the bottle body 110 to be labeled after the completion of the filling and capping is placed on the first conveyor belt 211, the bottle bottom 113 thereof is placed on the upper surface of the first conveyor belt 211, and the whole bottle body 110 is vertically conveyed to the gripping device 230 in the direction D1.
In step S4, the two conveying belts 231 of the clamping device 230 clamp the middle section of the bottle 110 in the axial direction, and keep the bottle 110 in a vertical state and continue to convey along the direction D1, and at this time, the bottle bottom 113 of the bottle 110 is exposed downward. When the bottle 110 is conveyed to the conveying start point of the conveying belt 231 for clamping, the bottle sensor below the position senses the bottle 110 and generates a corresponding signal, when the signal is received, the bottom labeling device 240 peels off a self-adhesive label, the self-adhesive label is inclined upwards, and in the process that the bottle 110 is continuously clamped and conveyed by the clamping device 230, the self-adhesive label is attached to the bottle bottom 113 moving through the position, so that the self-adhesive label 130 is formed, and the bottle bottom labeling is completed.
In step S5, the two conveying belts 231 of the gripping device 230 grip the bottle 110 and keep the bottle 110 in a vertical state and continue to convey in the direction D1, and at the conveying end of the conveying belt 231, the bottle 110 leaves the end of the conveying belt 231 as the conveying belt 231 rotates and falls to the conveying start point of the second conveying belt 221 below the end of the conveying belt 231, and then the second conveying belt 221 continues to convey the bottle 110 in the direction D1 to below the heat shrink label device 250.
In step S6, when the bottle 110 is conveyed to the predetermined position on the second conveyor belt 221, the second bottle sensor senses the bottle 110 and generates a corresponding signal, and when the signal is received, the heat shrink label sleeving device 250 sleeves the heat shrink label before heat shrink onto the bottle 110 at the predetermined position. Then, the heat shrink label sleeving device 250 circumferentially heats the bottle body 110 sleeved with the heat shrink label, so that the heat shrink label circumferentially shrink-wraps the bottle body 111. Then, the heat shrinkage label sleeving device 250 clamps the bottle body 110, and carries out directional heating on the heat shrinkage label part around the bottle bottom 113, so that the heat shrinkage label part shrinks and closes towards the middle part of the bottle bottom 113, thereby forming the heat shrinkage label 140, and obtaining the full-bottle light-blocking barrier bottle 100.
In this embodiment, the portions not described in detail are known in the art.
Operation and Effect of embodiment one
According to the barrier bottle 100 and the manufacturing method thereof provided by the embodiment, the method comprises the steps of arranging a light-blocking self-adhesive label 130 on the outer surface of the bottle bottom and arranging a light-blocking heat-shrinkable label 140 on the outer periphery of the bottle body, and enabling the heat-shrinkable label 140 to at least cover the edge part of the self-adhesive label 130, thereby forming the barrier bottle 100. Because the light blocking of the whole bottle body 110 is realized through the self-adhesive label 130 and the heat shrinkage label 140 of the bottle bottom 113, the bottle bottom 113 also has no light leakage, the barrier bottle 100 can realize an ideal light blocking effect, and the contents such as drinks in the barrier bottle 100 can have longer shelf life. Because the light blocking effect of the whole bottle is realized through the self-adhesive label 130 and the heat-shrinkable label 140 of the bottle bottom 113, the bottle body 110 can be made of conventional materials without adding light blocking agent, after the beverage and the like in the bottle are consumed, the self-adhesive label 130 and the heat-shrinkable label 140 are removed, and the bottle body and the bottle cap can be recovered and reused in a conventional manner. In addition, compared with the existing methods of spraying or dip-coating a barrier coating on the outer wall of the bottle bottom, manufacturing a sleeve bottle holder on the bottle bottom and the like, the manufacturing method of the embodiment has the advantages of relatively simple process, less equipment investment and contribution to realizing batch production.
In the embodiment, the black self-adhesive label 130 is adopted, so that the cost of the self-adhesive label is low and the self-adhesive label is easy to set compared with the existing modes of spraying or dip-coating a barrier coating on the outer wall of the bottle bottom, manufacturing a bottle holder on the bottle bottom and the like while effective light blocking is realized. Further, the self-adhesive label 130 is a water-washable self-adhesive label, which can be conveniently removed after washing with water, and the outer surface of the bottle bottom 113 is free from self-adhesive marks, so that the recycling difficulty is greatly reduced.
In the embodiment, after the light-blocking heat-shrinkable label 140 is sleeved on the outer periphery of the bottle body 110, the outer surface of the bottle cap 120 and the edge part of the outer surface of the self-adhesive label 130 are coated by heat shrinkage, so that the light blocking of the whole bottle is effectively realized, the self-adhesive label 130 is further reinforced, the self-adhesive label cannot easily fall off, and the reliability of the blocking bottle 100 is improved. The heat shrinkage label has mature process and high production efficiency, and can utilize the existing heat shrinkage label sleeving equipment, and the additional equipment cost is low. In addition, the light blocking layer of the heat shrinkable label 140 is disposed on the inner surface of the bottle body 110, so that the arrangement of the light blocking layer does not affect the design and printing of the outer surface of the heat shrinkable label 140, i.e. the appearance of the outer surface of the heat blocking bottle 100 is not affected while the light blocking effect is achieved.
In the embodiment, the bottle 110 to be labeled is conveyed by the first and second horizontal conveyor belts 211 and 221, and the bottle 110 is held by the two parallel holding conveyor belts 231 so that the bottle bottom 113 is exposed downward, and the bottom label is applied from below. Thus, the bottle body 110 does not need to be turned over in the bottom labeling process, and the two parallel clamping conveying belts 231 also play a role in clamping and fixing at the same time, so that the bottle body 110 cannot turn over or the like due to the acting force of bottom labeling, and therefore, the bottle body is not required to be additionally positioned and fixed, the production efficiency is improved, and the influence of illumination on beverages in the bottle in the production process can be reduced.
In the embodiment, the heat shrinkage label sleeving device 250 firstly circumferentially heats the heat shrinkage label 140 sleeved on the periphery of the bottle body 110, so that the heat shrinkage label is circumferentially shrunk and coated on the bottle body 111, and then the heat shrinkage label part around the bottle bottom 113 is heated, so that the heat shrinkage label is closed towards the middle of the bottle bottom 113, thereby ensuring that the heat shrinkage label 140 well coats and presses the self-adhesive label 130, ensuring the light blocking effect, ensuring that the bottle bottom of the finished product blocking bottle 100 can be kept relatively flat, being easier to stack and convey, and avoiding the conditions of skew, dumping and the like caused by uneven coating of the bottle bottom when placed on a shelf.
< example two >
The present embodiment provides a method for manufacturing a barrier bottle and a barrier bottle, and in the present embodiment, the same reference numerals are given to constituent elements having the same structure as those of the first embodiment, and the corresponding description is omitted.
Fig. 8 is a side view of the barrier bottle in this embodiment.
As shown in fig. 8, in the barrier bottle 100 'of the present embodiment, the bottle cap 120' is also made of a conventional PE material without a light blocking agent or an oxygen blocking agent, and the color is black, and in the alternative, may be other dark colors such as deep blue. Because the dark color bottle cap 120 'has an ideal light blocking effect, the heat shrinkable label 140' of the present embodiment only covers the outer surface of the bottle body 111, the edge portion of the self-adhesive label 130, and a small portion of the outer edge of the bottle cap 120', but does not cover the entire outer surface of the bottle cap 120'.
In the method for manufacturing the barrier bottle 100 'of the present embodiment, in step S6, the heat-shrinkable label sleeving device 250 is sleeved on the bottle body 110 with a heat-shrinkable label having a corresponding height (i.e. the height of the label before heat shrinkage is smaller than that of the label in the first embodiment), and the heat-shrinkable label is heated to shrink and cover the bottle body 110 and the edge portion of the self-adhesive label 130, and the shrunk heat-shrinkable label 140 does not cover the entire outer surface of the bottle cap 120'. The other manufacturing steps are the same as in the first embodiment.
In this embodiment, other structures and effects are the same as those in the first embodiment, and thus the description thereof will not be repeated.
The actions and effects of the second embodiment
According to the barrier bottle 100' and the manufacturing method thereof provided by the embodiment, on the basis of the technical effect of the first embodiment, as the light blocking effect is achieved through the black bottle cap 120', the heat shrinkage label 140' does not need to cover the bottle cap 120', so that the heat shrinkage label 140' has fewer materials, lower cost and environmental protection; in addition, because the structure of the bottle mouth and the bottle cap is more complex relative to the bottle body, a specific heat shrinkage process is needed to realize the ideal coating effect, and in the embodiment, only the bottle body part with a relatively simple coating structure is needed because the bottle cap 120' is not required to be coated any more, the heat shrinkage process is simpler, the cost of the product is reduced, and the production efficiency is improved.
The above examples are only for illustrating the specific embodiments of the present invention, and the present invention is not limited to the description scope of the above examples.
In the above embodiments, the barrier bottle is used for filling drinks with high protein content, and in practice, the barrier bottle may also be used for filling other drinks, health care medicines, etc. that have light blocking requirements.
In the above embodiment, the outer surface of the bottle bottom is substantially flat to facilitate labeling, but in the alternative, the bottle bottom may be other shapes as long as it has a flat surface with enough area to facilitate labeling, for example, the bottle bottom may be a structure with a concave part toward the inside of the bottle, the concave part is a substantially flat annular plane, and the circular self-adhesive label is aligned and attached on the annular plane, so that corresponding technical effects can be achieved.
In the above embodiments the closure is also made of conventional PE material, but in the alternative the closure may be made of other materials, for example also aluminium.
In the above embodiment, the bottle body is clamped by two parallel conveying belts, so that the bottle bottom is exposed downwards, and the bottom labeling device labels the bottle bottom from the lower side, in an alternative scheme, other modes can be adopted to label the bottle bottom, for example, after the bottle body to be labeled is overturned by a mechanical arm, a self-adhesive label is attached to the bottle bottom upwards after overturning by using the equipment for labeling the upper surface in the prior art, and the corresponding technical effect can also be achieved.
