Description

Technical Field

[0001] The utility model relates to the technical field of packaging equipment, in particular to a labeling production line with a function of adjusting the distance between medicine bottles. Background Art

[0002] After the Chinese patent medicine is concentrated and made into pill granules or capsules, it needs to be filled into medicine bottles according to a set quantity. After covering the bottle cap on the bottle mouth of the medicine bottle, it is also necessary to paste a label on the outer peripheral surface of the medicine bottle.

[0003] The labeling production line of the prior art is equipped with a labeling machine. The labeling machine is provided with a label output port, a label rolling device and a baffle at the labeling station. A labeling channel is formed between the label rolling device and the baffle. The label output port is located at the input end of the labeling channel. A batch of medicine bottles to be labeled are sequentially conveyed to the labeling channel through a conveyor belt, so that the medicine bottles to be labeled complete labeling one by one through the labeling channel.

[0004] If the distance between two adjacent medicine bottles to be labeled arranged on the conveying surface of the conveyor belt is less than the moving distance of the medicine bottle to complete labeling in the labeling channel, there will be a phenomenon that one medicine bottle has not completed labeling in the labeling channel while another medicine bottle has entered the input end of the labeling channel, and a label will be pasted on the outer peripheral surfaces of the two medicine bottles. Subsequently, it is necessary to manually remove the label and clean the outer peripheral surfaces of the two medicine bottles, which reduces the production efficiency.

[0005] If the distance between two adjacent medicine bottles to be labeled arranged on the conveying surface of the conveyor belt is greater than the moving distance of the medicine bottle to complete labeling in the labeling channel, when one medicine bottle completes labeling in the labeling channel and another medicine bottle has not entered the input end of the labeling channel, the label output port has already output the second label. This will not only waste labels, but also cause the second label to be pasted on the side wall of the labeling channel, resulting in the need to stop the machine to clean the labeling channel, which reduces the production efficiency.

[0025] A labeling production line with a function of adjusting the spacing between medicine bottles, comprising a conveyor belt 10 and a labeling machine 2. The labeling production line is provided with a labeling station 11. The labeling machine 2 includes a label roll device 21 and a baffle 22. The label roll device 21 and the baffle 22 are mounted above the conveyor belt 10 at a left-right interval. The label roll device 21 and the baffle 22 are located at the labeling station 11. A labeling channel 201 is formed between the label roll device 21 and the baffle 22. The production line further includes a spacing adjustment device 3;

[0026] The spacing adjustment device 3 includes two turntables 31; the two turntables 31 approach from the left and right sides of the conveyor belt 10 respectively and are mounted above the conveyor belt 10. The central axis of the turntable 31 is perpendicular to the conveying surface of the conveyor belt 10, and the bottom surface of the turntable 31 is close to the conveying surface of the conveyor belt 10; the two turntables 31 rotate in opposite directions, and the labeling station 11 is located in front of the running directions of the two turntables 31; a plurality of grooves 311 are provided on one of the turntables 31, and the plurality of grooves 311 are equidistantly distributed on the outer peripheral surface of the turntable 31, and the grooves 311 penetrate through the turntable 31 from top to bottom; the grooves 311 are used for accommodating a medicine bottle 6 conveyed by the conveyor belt 10 to the labeling channel 201.

[0027] Figure 1 It is a schematic structural diagram of an embodiment of a labeling production line with a function of adjusting the spacing between medicine bottles of the present invention. Figure 2 It is a schematic structural diagram of an embodiment of the spacing adjustment device 3 of the present invention. Figure 1 The labeling machine 2 in [description] is provided with a label output port 20. The label output port 20 is located at the input end of the labeling channel 201, and the conveyor belt 10 runs from back to front.

[0028] For the labeling production line with a function of adjusting the spacing between medicine bottles of the present invention, the adopted spacing adjustment device 3 includes two turntables 31; the spacing between two medicine bottles 6 output from two adjacent grooves 311 can be adjusted by adjusting the rotation speeds of the two turntables 31.

[0029] If it is necessary to avoid the phenomenon that a label is pasted on the outer peripheral surfaces of two medicine bottles and avoid label waste and rework, it is only necessary to adjust the rotation speeds of the two turntables 31 so that the spacing between two medicine bottles 6 output from two adjacent grooves 311 is the same as the moving distance of any medicine bottle 6 for completing labeling in the labeling channel 201.

[0030] Specifically, the spacing adjustment device 3 includes a driver 30, a transmission rod 34, a sprocket transmission assembly 33, two rotating shafts 32 and the two turntables 31;

[0031] The sprocket drive assembly 33 includes an output gear 331, a drive gear 332, a drive chain 333, two first driven gears 334, and two second driven gears 335;

[0032] The driver 30 is installed near the turntable 31 below the conveyor belt 10; the transmission rod 34 is mounted below the conveyor belt 10; the output end of the driver 30 and the transmission rod 34 extend respectively in a direction perpendicular to the running direction of the conveyor belt 10; both ends of the transmission rod 34 are exposed on both sides of the conveyor belt 10;

[0033] The output gear 331 is sleeved on the output end of the driver 30, and the drive gear 332 is sleeved in the middle of the transmission rod 34; the drive chain 333 is sleeved on the outer peripheral surface of the output gear 331 and the outer peripheral surface of the drive gear 332, and the drive chain 333 drives the output gear 331 and the drive gear 332 to rotate synchronously; the two first driven gears 334 are respectively sleeved on both ends of the transmission rod 34; the two second driven gears 335 are respectively sleeved on the lower ends of the two rotating shafts 32; the two first driven gears 334 and the two second driven gears 335 are meshed with each other in one-to-one correspondence; the turntable 31 is sleeved on the outer peripheral surface of the corresponding rotating shaft 32.

[0034] As Figure 1 and Figure 2 shown, through the cooperation of the output gear 331, the drive gear 332 and the drive chain 333, the driver 30 drives the transmission rod 34 to rotate, and through the two first driven gears 334 and the two second driven gears 335 that are meshed with each other in one-to-one correspondence, drives the two rotating shafts 32 to rotate synchronously and in opposite directions, and further drives the two turntables to rotate synchronously in opposite directions.

[0035] Preferably, the distance between the two rotating shafts 32 is adjustable.

[0036] As Figure 1 shown, by adjusting the distance between the two rotating shafts 32, the distance between the outer peripheral surfaces of the two turntables 31 can be adjusted, so that the labeling production line with the function of adjusting the distance between medicine bottles can be applicable to the labeling production of medicine bottles with different outer diameters.

[0037] Preferably, the arc distance between two adjacent grooves 311 is the same as the horizontal length of the labeling channel 201.

[0038] The linear velocity of the conveyor belt 10 can be set with reference to the length of the label to be pasted and the horizontal length of the labeling channel 201, so that the moving distance of the medicine bottle 6 during labeling in the labeling channel 201 is equal to the horizontal length of the labeling channel 201. Also, the arc distance between two adjacent grooves 311 is set to be the same as the horizontal length of the labeling channel 201. In this way, the linear velocities of the two turntables 31 during rotation and the linear velocity of the conveyor belt 10 during operation can be kept the same for labeling production. This can not only improve the smoothness of the movement of the medicine bottles to be labeled on the conveying surface, but also enable the labeling production line with the function of adjusting the spacing between medicine bottles to have a high production efficiency.

[0039] Further, it also includes multiple railings 12;

[0040] The multiple railings 12 are divided into two groups; the two groups of railings 12 extend respectively along the extending direction of the conveyor belt 12 and are respectively mounted on the left and right sides of the conveying surface.

[0041] As Figure 1 shown, setting two groups of railings 12 on the left and right sides of the conveying surface can prevent the misaligned medicine bottles from falling outside the conveyor belt 10.

[0042] In summary, as Figure 1-2 shown in the embodiment of the present invention, for a labeling production line with the function of adjusting the spacing between medicine bottles proposed by the present invention, the spacing adjustment device 3 includes two turntables 31. By adjusting the rotation speeds of the two turntables 31, the spacing between two medicine bottles 6 output from two adjacent grooves 311 can be made the same as the moving distance of a medicine bottle 6 during labeling in the labeling channel 201. This can avoid the phenomenon that one label is pasted on the outer circumferential surfaces of two medicine bottles and the waste of labels, thereby reducing the cleaning work and improving the production efficiency.

[0043] The technical principle of the present invention has been described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted in any way as a limitation on the protection scope of the present invention. Based on this explanation, those skilled in the art can think of other specific embodiments of the present invention without creative labor, and these embodiments will fall within the protection scope of the present invention.
