Description

Technical Field

[0001] The present invention relates to the technical field of label wrapping machines, and particularly to an automatic deviation-correcting label wrapping machine. Background Art

[0002] In modern industrial product packaging assembly lines, it is necessary to paste and wrap labels on the produced industrial products. Using manual labor will have problems such as low efficiency and deviation of the pasting position. Therefore, automated label wrapping machines often replace manual labor and are set in the packaging assembly line.

[0003] In the existing automatic label pasting / wrapping machines, when positioning the material, they can often only adjust the alignment degree of the labels in the front-back direction, that is, they only have one-axis deviation correction ability. For example, the patent document with the publication number CN214524972U discloses a filter automatic labeling device, which sets a label detection sensor on the transmission path of the roll-type label to detect the label position, and drives the telescopic movement of the label guiding roller through a motor to correct the deviation of the label transmission. It only has one-axis deviation correction ability and can only adjust the front-back position of the label relative to the material. When the label sent out is deflected due to other reasons such as the tilting of the label output device, its deviation correction ability is insufficient and it cannot correct the deflected label. At this time, manual intervention is required, increasing the use and maintenance costs. Summary of the Invention

[0004] The present invention provides an automatic deviation-correcting label wrapping machine to solve the problem that the existing automatic label pasting / wrapping machines only have one-axis deviation correction ability and cannot correct the deflected labels.

[0044] Referring to "embodiments" in this context means that the specific features, structures, or characteristics described in connection with the embodiments may be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0045] The present invention provides an automatic deviation-correcting labeling machine, such as Figure 1 and Figure 2As shown, the workbench 1 supports other devices. The upper surface of the workbench 1 has a long strip-shaped opening, and handling tracks 11 are provided on both sides of the opening; the label dispensing device 2 is arranged at one end of the handling track 11, and the label dispensing direction points to the handling track 11; the label applying device 3 straddles the handling track 11 and is close to the label dispensing side of the label dispensing device 2; the discharging device 5 is arranged at the other end of the handling track 11; the loading and unloading device 4 is arranged parallel to the handling track 11; the handling platform 6 is installed on the handling track 11 and is driven by the handling track 11, and can slide along the handling track 11; the controller 7 is installed on the workbench 1, controls the movement of other devices, and does not interfere with other devices in terms of position. The specific structures and functions of each device are described in detail below.

[0046] As Figure 3 and Figure 4 shown, the label dispensing device 2 mainly includes a label dispensing base 21, a label dispensing rotating frame 22 and a label rack 23. The label dispensing rotating frame 22 is installed on the label dispensing base 21. The label dispensing base 21 is provided with a driver and a track, and can drive the label dispensing rotating frame 22 to slide on the label dispensing base 21; the label dispensing rotating frame 22 itself has a rotating shaft, the lower part of which is installed on the label dispensing base 21, and the rotating shaft of the upper part is installed and connected to the label rack 23, that is, the label dispensing rotating frame 22 can drive the label rack 23 to rotate around the rotating shaft of the label dispensing rotating frame 22; the label dispensing turntable 231 is installed on the top of the label rack 23, and the detachable and replaceable label reel 8 is installed on the label dispensing turntable 231, on which a label tape (multiple labels 81 are arranged in the label tape) is wound, and the label tape of the label reel 8 is released by the rotation of the label dispensing turntable 231; a plurality of tension rollers 232 are also arranged on the label rack 23. After the label tape passes through and bypasses each tension roller 232, it is wound by the winding roller 234; at the end of the label rack 23 where the label exits, a first detection optical fiber 233 is provided, which detects the position of the label 81 in the feeding direction.

[0047] For each label 81, in its own feeding direction, the label dispensing turntable 231 controls the feeding linear motion in this direction; the label dispensing base 21 can control the movement of the label dispensing rotating frame 22 in the direction perpendicular to the feeding direction in the horizontal plane, indirectly controlling the movement of the label 81 in this direction; the label dispensing rotating frame 22 controls the rotation of the label rack 23 around the vertical axis, and thus indirectly controls the rotation of the label 81 around the vertical axis; in summary, the label 81 has two degrees of freedom in the linear direction and one degree of freedom of rotation around the vertical axis, that is, the label 81 can be corrected by three axes.

[0048] As Figure 5 and Figure 6As shown in the figure, the entire labeling device 3 is carried by a gantry-shaped labeling frame 31 which holds all the components; a linear labeling module 32 is installed on the labeling frame 31 and drives the gripper 33 to move linearly. The gripper 33 is installed on the side close to the discharging device 5, and its longitudinal height can be finely adjusted; a label wrapping roller frame 34 is fixedly installed below the gripper 33 on the labeling frame 31. The label wrapping roller frame 34 is in the shape of a pair of pincers, and on each of the two opposite inner sides, rollers are provided along the upper and lower edges. The material with the label 81 pasted on its upper surface passes through the label wrapping roller frame 34 from bottom to top and is sent to the gripper 33. At the same time, the rollers on the two inner sides of the lower edge of the label wrapping roller frame 34 will bend the parts of the label 81 that exceed the upper surface of the material on both sides downward. Then, the gripper 33 drives the material to move linearly, so that the material is respectively rolled by the rollers on both sides of the upper edge of the label wrapping roller frame 34, thereby completing the overall surrounding and wrapping of the label 81 around the material.

[0049] On the side of the labeling device 3 close to the label feeding device 2, a pressure labeling roller 35 that can move longitudinally is installed, which can press the label 81 sent out by the label feeding device 2 onto the upper surface of the material; on the side of the labeling device 3 close to the label feeding device 2, a detection optical fiber frame 36 is also installed (in a specific embodiment of the present invention, the fixed parts of the detection optical fiber frame 36 and the pressure labeling roller 35 are installed and connected together), and a second detection optical fiber 361 and a third detection optical fiber 362 are installed on it with adjustable positions.

[0050] As Figure 7 shown in the figure, the loading and unloading device 4 is carried by a loading and unloading frame 41 which holds other components. A linear loading and unloading module 42 is horizontally fixedly installed on the loading and unloading frame 41 and drives a suction cup frame 43 to move linearly; the suction cup frame 43 itself can drive the suction cups 44 to move linearly longitudinally and suck the material; a finished product conveyor belt 45 is fixedly installed on the back side of the loading and unloading frame 41.

[0051] As Figure 8 shown in the figure, in the discharging device 5, a discharging base 51 supports at the bottommost part. A silo 52 is erected in a cylindrical shape on the discharging base 51, and it has an opening at its lower part. The materials to be labeled are longitudinally stacked in the silo 52, and the height of the opening is greater than the thickness of one material and less than twice the thickness of the material; a sliding plate 53 is driven by a discharging linear module installed on the discharging base 51 and can take out the materials in the silo 52. Due to the height limitation of the opening of the silo 52, the sliding plate 53 can only take out one material at a time.

[0052] As Figure 9 shown in the figure, in the handling platform 6, a platform frame 61 is fitted and installed with a handling track 11, and a clamping plate 62 that can clamp the material is provided in the middle of the handling platform 6, and a lifting cylinder 63 that can lift the clamping plate 62 is installed below the handling platform 6.

[0053] In the present invention, the specific process of attaching the label is as follows: The sliding plate 53 of the discharging device 5 sends out the material. The suction cup 44 of the loading and unloading device 4 picks up the material and sends it to the clamping plate 62 of the handling platform 6. The clamping plate 62 carries the material to the pressing label roller 35 of the label attaching device 3. The label feeding device 2 sends out the adjusted label 81. The pressing label roller 35 presses the label 81 onto the material. The clamping plate 62 is lifted to the clamping jaw 33 of the label attaching device 3. After the bagging label is completed by the operation of the clamping jaw 33 as described above, the clamping jaw 33 carries the material to the finished product conveyor belt 45 of the loading and unloading device 4.

[0054] For the adjustment of the label 81 by the label feeding device 2 in the present invention, it is necessary to identify the specific state of the label 81, such as Figure 10 and Figure 11 shown, the first detection optical fiber 233, the second detection optical fiber 361 and the third detection optical fiber 362 respectively irradiate the first detection point 2331, the second detection point 3611 and the third detection point 3621 on the label tape. Since the label tape is white and the label 81 has other colors, each detection optical fiber can sense whether the irradiation point is on the label tape or on the label 81 by perceiving the change in the light reflected at the irradiation point. In the present invention, the label is in the shape of a long rectangle. Taking the feeding direction marked in Figure 10 as a reference, in the plane where the label 81 is located, the line connecting the second detection point 3611 and the third detection point 3621 is perpendicular to the feeding direction, and the length of the line is the same as the length of the longer side of the label 81. The first detection point 2331 is behind the second detection point 3611 and the third detection point 3621 in the feeding direction. When the first detection point 2331 irradiates the rear side edge of the label 81, through the cooperation of the label feeding turntable 231, the label feeding base 21 and the label feeding rotating frame 22, it is adjusted so that the second detection point 3611 and the third detection point 3621 respectively irradiate the two narrow sides of the label 81. At this time, the position of the label 81 is adjusted.

[0055] In another embodiment of the present invention, as Figure 12 shown, the arrangement of the second detection optical fiber 361 and the third detection optical fiber 362 can be changed so that when the position of the label 81 is adjusted, the line connecting the second detection point 3611 and the third detection point 3621 is parallel to the feeding direction and both irradiate on one of the narrow sides of the label 81. In addition, the length of the line connecting the second detection point 3611 and the third detection point 3621 should also be less than or equal to the length of the narrow side of the label 81.

[0056] The above-described embodiments merely represent the implementation manners of the present invention. Their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
