As shown in fig. 1 to 7, an embodiment of the present invention provides a label roll counting device for counting and confirming the number of labels 202 on a source label roll 100 of a whole roll. Specifically, as shown in fig. 1 to 3, the label winding counting device comprises a mounting frame 10, and a feeding mechanism 20, a winding mechanism 30 and a counting mechanism 40 which are mounted on the mounting frame.

The mounting bracket 10 includes a mounting base plate 11 and a support plate 12 vertically disposed on the mounting base plate 11.

The feeding mechanism 20 is used for mounting the source label roll 100 and for conveying the label tape 200 wound on the source label roll 100; specifically, the feeding mechanism 20 is mounted on the support plate 12, and the source label roll 100 is mounted on the feeding mechanism 20 and is capable of releasing the label tape 200 wound thereon for subsequent counting and secondary winding processes.

The winding mechanism 30 is used for performing secondary winding on the label tape 200 released from the source label roll 100 to form a new label roll; specifically, the feed mechanism 20 is also mounted to the support plate 12.

The counting mechanism 40 is configured to count the number of the labels 202 on the label tape 200 before the winding mechanism 30 winds the label tape 200 for the second time; specifically, the counting mechanism 40, the feeding mechanism 20 and the winding mechanism 30 are all mounted on the support plate 12, and the label tape 200 released from the source label roll 100 is conveyed to the counting mechanism 40 for counting labels 202, and then conveyed to the winding mechanism 30 for secondary winding to form a new label roll.

When the label winding counting device of the embodiment of the present invention is used, the source label roll 100 of the whole roll is mounted on the feeding mechanism 20, then the label tape 200 released from the source label roll 100 is transported to the winding mechanism 30, the winding mechanism 30 is started to perform the secondary winding of the label tape 200, and before the label tape 200 is subjected to the secondary winding, the counting mechanism 40 on the mounting rack 10 counts the number of the labels 202 on the label tape 200 to confirm the number of the labels 202 after the secondary winding. In this way, the winding mechanism 30 is arranged to wind the label tape 200 wound on the source label roll 100 for the second time, and the counting mechanism 40 is used to measure the number of labels 202 on the label tape 200 to be wound for the second time while the label tape is wound for the second time, so that the number of the labels 202 can be checked and confirmed according to the actual use requirement, and the labels 202 with the corresponding number can be provided according to the pasting requirement of the labels 202, thereby avoiding the occurrence of label missing caused by insufficient number of the labels 202 in the pasting process of the labels 202; in addition, before the label 202 is attached, the label tape 200 is wound for the second time in a unified manner to form a new label roll, the label discharging modes of the label roll after the second winding are consistent, and the phenomenon that the labeling equipment works abnormally due to different label discharging modes of the label 202 is avoided, so that the processing time of the abnormal label discharging can be saved, the smoothness of the labeling process is improved, and the production efficiency is improved.

Specifically, as shown in fig. 2 and 3, the label tape 200 released from the source label roll 100 passes through the sensing gap 411 and then is conveyed to the winding mechanism 30 for secondary winding, when the label tape 200 passes through the sensing gap 411, the label sensor counts the labels 202 on the label tape 200, the number information is fed back to the sensing counter 42 after the label sensor counts, the sensing counter 42 accumulates and superposes the number of the labels 202, and displays the number of the measured labels 202, so that an operator can judge whether the number of the labels 202 on the label roll after secondary winding meets the use requirement according to the number displayed by the sensing counter 42, the number measuring process is more intuitive, and the use is more convenient.

In the present embodiment, the label sensor is a thickness sensor, and the thickness sensor obtains and confirms the number of labels 202 on the label tape 200 by sensing the thickness variation information of the label tape 200. Generally, as shown in fig. 7, the label tape 200 includes a base paper 201 and a plurality of labels 202 adhered to the base paper 201, two adjacent labels 202 are disposed at an interval and form a blank area 203 for cutting the labels 202 at the interval, and the thickness of the area where the labels 202 are adhered is greater than the thickness of the blank area 203 where no label 202 is adhered, so that the thickness sensor can sense and confirm the number of the labels 202 on the base paper 201 with the thickness variation of the label tape 200, thereby achieving the purpose of counting the labels 202 one by one.

Preferably, in this embodiment, the thickness sensor is an optical fiber sensor, and the labels 202 are counted by using different influences (such as different influences on the intensity, wavelength, frequency, phase, and the like) of the blank base paper 201 and the base paper 201 on which the labels 202 are attached to the light. Of course, in some other embodiments, other label sensors may be used to perform sensing counting on the label 202, for example, when the base paper 201 and the label 202 have different colors, a sensor capable of sensing color change may be used to perform sensing on the label 202.

So, through the spacing distance between adjusting connection board 414 and mounting bracket 10 (backup pad 12), adjust the distance between response clearance 411 and the backup pad 12, avoid inductor installed part 41 to obstruct the normal removal of label area 200 for the normal response of guaranteeing the label inductor is guaranteed in the response clearance 411 that passes that different width dimension's label area 200 homoenergetic is smooth.

In another embodiment of the present invention, as shown in fig. 1, 2 and 5, the feeding mechanism 20 comprises a second rotating shaft 21 rotatably mounted on the mounting frame 10 and a second roll-tensioning assembly 22 for tensioning and fixing the roll of the source label roll 100 on the second rotating shaft 21, the second roll-tensioning assembly 22 comprises a second inner sleeve 221, a second elastic middle sleeve 222 and a second adjusting nut 223; the second inner sleeve 221 is sleeved on the second rotating shaft 21, the second elastic middle sleeve 222 is sleeved outside the second inner sleeve 221 and used for sleeving the reel of the source label roll 100, the second adjusting nut 223 is rotatably connected to the end portion of the second rotating shaft 21 extending out of the second elastic middle sleeve 222, and the second adjusting nut 223 is rotatably close to the second elastic middle sleeve 222 on the second rotating shaft 21, so that the second adjusting nut 223 extrudes the second elastic middle sleeve 222 to tension and fix the reel of the source label roll 100 on the second rotating shaft 21. Likewise, in this embodiment, to ensure the sleeving stability of the second inner sleeve 221, the winding mechanism 30 further includes a second baffle 224, a second fixed ring 225 and a second connecting ring 226. Specifically, the specific structure, the connection manner between the structures, and the tensioning principle of the second reel tensioning assembly 22 are the same as those of the first reel tensioning assembly 34, and therefore, the detailed description thereof is omitted.

In another embodiment of the present invention, as shown in fig. 2 and 5, the feeding mechanism 20 further includes an emergency stop assembly 23 for clamping the second rotating shaft 21 and forcing the second rotating shaft 21 to stop rotating, the emergency stop assembly 23 includes a first pair of clamping members 231 and a second pair of clamping members 232, the first pair of clamping members 231 and the second pair of clamping members 232 are disposed opposite to each other and reserve a clamping gap for the second rotating shaft 21 to pass through, both the first pair of clamping members 231 and the second pair of clamping members 232 are rotatably mounted on the mounting frame 10, and the first pair of clamping members 231 and the second pair of clamping members 232 are rotated on the mounting frame 10 to clamp the second rotating shaft 21, so that the second rotating shaft 21 stops rotating.
