Description
Technical Field
[0001] The utility model relates to the technical field of product packaging, in particular to a labeling mechanism capable of labeling on both sides. Background Art
[0002] The labeling line is an important part of the automated production line, and is mainly used to automatically attach labels to products or packages. The labeling line usually includes a material conveying line, a label printing mechanism, and a labeling mechanism. The material conveying line usually conveys the material to be labeled through a conveyor belt. The material can be a product or the outer packaging of the product. The label printing mechanism usually includes a reeling component, a printing component, a peeling component, and a paper outlet. The reeling component can unwind the release paper with the label, the printing component can print product information such as product batch, serial number, and code on the label, and the peeling component can peel the printed label from the release paper, and then give the printed label through the paper outlet. The labeling mechanism usually takes the label from the paper outlet and then applies the label to the product or the outer packaging of the product. The existing labeling mechanism is often only able to apply a label to one side of the product or the outer packaging of the product. For the need to label the product or the outer packaging of the product on two adjacent sides, the usual practice is to set up two sets of labeling mechanisms to label the two adjacent sides of the product or the outer packaging of the product, respectively, resulting in equipment redundancy and high cost.

[0034] It is easy to understand that according to the technical solution of the utility model, without changing the essential spirit of the utility model, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the utility model, and should not be regarded as the entirety of the utility model or as a limitation or restriction on the technical solution of the utility model.
[0035] according to Figure 1 As shown, the material conveying line 200 continuously conveys the material 201 through the conveyor belt, and the label printing mechanism 300 is arranged at the label printing station on one side of the material conveying line 200. The labeling mechanism 100 capable of labeling on both sides is suitable for applying the labels printed by the label printing mechanism 300 to the two adjacent surfaces of the material 201 in sequence. The label printing mechanism 300 includes an unwinding component 301, a printing component 302, a peeling component 303 and a paper outlet 304. The unwinding component 301 is suitable for unwinding the release paper with the label on the unwinding shaft, and the release paper with the label is wound and passed through multiple rollers in sequence. The product information of the material 201 is printed on the surface of the empty label through the printing component 302. The product information can be the material 201 code, the material 201 batch, the product serial number, the traceability code, etc., which is not specifically limited. The printed label is peeled off from the release paper through the peeling component 303, and the printed label is sent out from the paper outlet 304.
[0036] according to Figure 2 As shown, after the labeling mechanism 100 applies a label to one surface of the material 201 (specifically, it can be the front surface of the material 201), the material 201 is continuously transported downstream for a distance, and the labeling mechanism 100 grabs the label from the paper outlet 304 of the label printing mechanism 300 again, and applies it to another adjacent surface of the same material 201 (specifically, it can be the side surface of the material 201 adjacent to the front surface).
[0037] according to Figure 3 As shown, the labeling mechanism 100 includes a frame 1 and a swing labeling assembly 2. The swing labeling assembly 2 includes a swing power module 21 arranged on the frame 1, a swing arm 22 with one end connected to the swing power module 21, and a label taking and applying portion 23 arranged on the other end of the swing arm 22 and used for grabbing and applying labels.
[0038] Among them, the swing power module 21 can be a swing cylinder. In some embodiments, the swing power module 21 can also be a rotating motor. The label taking and sticking part 23 can be a vacuum suction cup. In some embodiments, the label taking and sticking part 23 can also be an electrostatic adsorption part, a clamp, a magnetic adsorption part or a sticky adsorption part, without specific limitation.
[0039] The label taking and applying part 23 is configured to be able to move between the label taking position and the first label applying position driven by the swing arm 22. Figure 3 As shown in FIG. , the label taking and applying portion 23 moves to the first labeling position.
[0040] Combination Fig. 9 and Fig.11 As shown, when the labeling mechanism 100 performs the labeling action for the first time, the label taking and sticking part 23 is in the label taking and sticking position. The label taking and sticking part 23 is suitable for grabbing the label printed at the paper outlet 304 of the label printing mechanism 300 at the label taking and sticking position. Then the swing power module 21 can drive one end of the swing arm 22 to rotate around an axis, driving the label taking and sticking part 23 on the other end of the swing arm 22 to move from the label taking and sticking position to the first labeling position. The label taking and sticking part 23 can apply the label to one surface of the material 201 (specifically, it can be the front surface of the material 201) at the first labeling position.
[0041] according to Figure 4 As shown, the label taking and applying part 23 is configured to be able to move between the label taking position and the second label applying position driven by the swing arm 22. Figure 4 The figure shows that the label taking and applying part 23 moves to the second label applying position.
[0042] Combination Fig.10 and Fig.11 As shown, when the labeling mechanism 100 performs the labeling action for the second time, the label taking and applying part 23 returns to the label taking position again, and the label taking and applying part 23 is suitable for grabbing the label printed at the paper outlet 304 of the label printing mechanism 300 at the label taking position. Then the swing power module 21 can drive one end of the swing arm 22 to rotate around an axis, driving the label taking and applying part 23 on the other end of the swing arm 22 to move from the label taking position to the second labeling position. The label taking and applying part 23 can apply the label to another surface adjacent to the material 201 (specifically, it can be the side surface of the material 201 adjacent to the front surface) at the second labeling position.
[0043] according to Fig.11 As shown, when the label applying part 23 completes the label applying operation at the first labeling position, the swing power module 21 can drive one end of the swing arm 22 to rotate in the opposite direction around an axis, so that the label applying part 23 moves from the first labeling position and returns to the label taking position. When the label applying part 23 completes the label applying operation at the second labeling position, the swing power module 21 can drive one end of the swing arm 22 to rotate in the opposite direction around an axis, so that the label applying part 23 moves from the second labeling position and returns to the label taking position.
[0044] according to Figure 5 , Figure 7 and Fig.12As shown, in one embodiment of the utility model, the labeling mechanism 100 includes a first detection element 3, a second detection element 6 and a controller 4. The first detection element 3 is arranged on the label taking and applying part 23 and is used to detect whether the label taking and applying part 23 contacts or approaches the material 201 to be labeled (specifically, to detect the surface of the material to be labeled). When the label taking and applying part 23 moves to the first labeling position or the second labeling position, the first detection element 3 will be triggered and the detection signal will be fed back to the controller; the second detection element 6 is used to detect whether the label taking and applying part 23 is reset to the label taking position. The second detection element 6 can be arranged on the frame 1 and adjacent to the label taking position, or it can be arranged on the swing power module 21 to detect whether the swing power module 21 is reset, and then detect whether the label taking and applying part 23 is reset to the label taking position, without specific limitation.
[0045] The controller 4 is connected to the first detection element 3, the second detection element 6 and the swing power module 21 by signals. When the first detection element 3 detects that the label taking and applying part 23 contacts or approaches the material 201 to be labeled, the controller 4 determines that the label taking and applying part 23 moves to the first labeling position or the second labeling position. The controller 4 is configured to control the swing power module 21 to stop driving the swing arm 22 to rotate based on the detection signal of the first detection element 3 so that the label taking and applying part 23 remains in the first labeling position or the second labeling position, or to control the swing power module 21 to drive the swing arm 22 to rotate in the opposite direction based on the detection signal of the first detection element 3 so that the label taking and applying part 23 moves to the label taking position. The controller 4 is also configured to control the swing power module 21 to stop driving the swing arm 22 to rotate based on the detection signal of the second detection element 6, so that the label taking and applying part 23 remains in the label taking position.
[0046] The controller 4 may be a PLC controller 4 or an industrial computer; the first detection element 3 and the second detection element 6 may be infrared sensors, proximity switches, photoelectric sensors, position sensors, etc., without specific limitation.
[0047] In particular, it should be noted that in other embodiments, the first detection element 3 and the second detection element 6 may not be provided. For example: by directly limiting the rotation angle of the swing arm 22, it is possible to determine whether the label taking and sticking part 23 has reached the label taking position, the first labeling position, and the second labeling position. As agreed, when the swing arm 22 rotates from the label taking position by a first angle, it reaches the first labeling position; when the swing arm 22 rotates from the label taking position by a second angle, it reaches the second labeling position. In this embodiment, since the controller 4 controls the swing power module 21 to drive the swing arm 22 to rotate at a fixed angle each time (the first angle or the second angle), this requires the material conveying line 200 to accurately convey the material 201 to the position corresponding to the first labeling position and the position corresponding to the second labeling position. It should be noted that, when the label taking and applying portion 23 moves from the label taking and applying position to the first label applying position driven by the swing arm 22, the label taking and applying portion 23 can be made roughly parallel to one surface of the material 201 (such as the front surface of the material 201), so that the entire label can be better applied to the material; and when the label taking and applying portion 23 moves from the label taking and applying position to the second label applying position driven by the swing arm 22, the label taking and applying portion 23 and another surface adjacent to the material 201 (such as the side surface of the material 201 adjacent to the front surface) form a certain angle, and the label on the label taking and applying portion 23 can only be partially attached to the other adjacent surface of the material 201 (that is, the label taking and applying portion 23 can only partially apply the label to the side surface of the material 201), as shown in Figure 8 (a), specifically, the end of the label on the label taking and applying portion 23 close to the clamping component 5 is attached to the side surface of the material 201.
[0048] Combination Figure 4 and Figure 6 As shown, in order to solve the above problems, the labeling mechanism 100 includes a clamping component 5, which is arranged at the downstream position of the swing labeling component 2 along the conveying direction of the material conveying line 200. The clamping component 5 includes a clamping portion 51, and the clamping portion 51 is constructed to further press and apply the label on another surface adjacent to the material 201 (specifically, it can be the side surface of the material 201 adjacent to the front surface) applied by the label taking and applying portion 23 at the second labeling position to the material.
[0049] Specifically, the pressing assembly 5 includes a fixed seat 52, a swing frame 53 and a first elastic member 54. One end of the swing frame 53 is rotatably connected to the fixed seat 52, the pressing portion 51 is arranged on the other end of the swing frame 53, and the first elastic member 54 is connected between the swing frame 53 and the fixed seat 52. This allows the pressing portion 51 to float on the fixed seat 52, so that the pressing portion 51 can maintain good contact when pressing the label. Among them, the pressing portion 51 can be a pressing roller rotatably arranged on one end of the swing frame 53.
[0050] Combination Fig.11As shown, after the label applying part 23 applies the label to the other surface adjacent to the material 201 (specifically, the side surface adjacent to the front surface of the material) at the second labeling position, the material 201 is transported downstream under the conveying of the conveyor belt of the material conveying line 200 and passes through the pressing assembly 5, and the pressing roller of the pressing assembly 5 can roll and contact the other surface adjacent to the material 201 (specifically, the side surface adjacent to the front surface of the material), and one end of the swing frame 53 can swing around the fixed seat 52 and make the first elastic member 54 in an elastic force storage state, so that the pressing roller can always apply pressure to the material 201 during the contact with the other surface adjacent to the material 201 (specifically, the side surface adjacent to the front surface of the material), and the label applied by the label applying part 23 at the second labeling position on the other surface adjacent to the material 201 (specifically, the side surface adjacent to the front surface of the material) is further pressed and applied to the material 201, as shown in FIG8 (b). Among them, the first elastic member 54 can be a tension spring or other elastic member, which is not specifically limited.
[0051] In addition, in another embodiment of the present invention, the pressing assembly 5 may further include a brush body fixedly mounted relative to the frame 1, and the pressing portion 51 may be bristles arranged on the brush body, without specific limitation. In yet another embodiment of the present invention, the pressing assembly 5 may further include a roller rotatably arranged relative to the frame 1, and the pressing portion 51 may be bristles arranged on the outer peripheral wall of the roller, without specific limitation.
[0052] Combination Figures 1 to 12As shown, the control process is implemented as follows: the material conveying line 200 stops after conveying the material 201 to the first designated position, and the label picking and applying part 23 is in the label picking position in the initial state. The label picking and applying part 23 grabs the label printed by the label printing mechanism 300, and then the controller 4 controls the swing power module 21 to drive the swing arm 22 to rotate, so that the label picking and applying part 23 moves from the label picking position toward the first labeling position until the first detection element 3 detects that the label picking and applying part 23 contacts or approaches the material 201 and feeds back the detection signal to the controller 4. The controller 4 determines that the label picking and applying part 23 moves to the first labeling position based on this, and then controls the swing power module 21 to stop driving the swing arm 22 to rotate, so that the label picking and applying part 23 remains in the first labeling position and applies the label to one surface of the material 201 (such as: it can be the front surface of the material 201). Next, the controller 4 controls the swing power module 21 to drive the swing arm 22 to rotate in the opposite direction, so that the label picking and pasting part 23 moves from the first labeling position toward the label taking position, until the second detection element 6 detects that the label picking and pasting part 23 is reset to the label taking position and feeds back the detection signal to the controller 4, and then the controller 4 controls the swing power module 21 to stop driving the swing arm 22 to rotate, so that the label picking and pasting part 23 remains in the label taking position, and the label picking and pasting part 23 grabs the label printed by the label printing mechanism 300. During this process, the material conveying line 200 stops after conveying the material 201 to the second designated position. Then the controller 4 controls the swing power module 21 to drive the swing arm 22 to rotate, so that the label taking and applying part 23 moves from the label taking position to the second label applying position, until the first detection element 3 detects that the label taking and applying part 23 contacts or approaches the material 201 and feeds back the detection signal to the controller 4. The controller 4 judges that the label taking and applying part 23 moves to the second label applying position, and then controls the swing power module 21 to stop driving the swing arm 22 to rotate, so that the label taking and applying part 23 remains at the second label applying position and applies the label to another surface adjacent to the material 201 (specifically, it can be the side surface adjacent to the front surface of the material 201). Next, the controller 4 controls the swing power module 21 to drive the swing arm 22 to rotate in the opposite direction, so that the label taking and applying part 23 moves from the second label applying position to the label taking position, until the second detection element 6 detects that the label taking and applying part 23 is reset to the label taking position and feeds back the detection signal to the controller 4. The controller 4 then controls the swing power module 21 to stop driving the swing arm 22 to rotate, so that the label taking and applying part 23 remains at the label taking position. In this embodiment, sensors may be provided at corresponding positions on the material conveying line 200 to detect whether the material 201 has reached the first designated position, the second designated position or other positions.
[0053] Of course, in other embodiments, the material 201 may not stop when it reaches the first designated position or the second designated position (that is, the material 201 may also be continuously conveyed forward), and the controller controls the label taking and applying part 23 to move to the first labeling position for labeling when the material 201 reaches the first designated position, and controls the label taking and applying part 23 to move to the second labeling position for labeling when the material 201 reaches the second designated position. After the label taking and applying part 23 applies the label to the material at the first labeling position or the second labeling position, the controller immediately controls the swing power module 21 to rotate in the opposite direction and reset so as not to affect the continuous forward conveying of the material 201, and the specific implementation method is not limited to this.
[0054] Combination Figure 3 and Figure 4 As shown, in order to enable the label taking and applying part 23 to be accurately positioned at the paper outlet 304 of the label printing mechanism 300 driven by the swing arm 22, the labeling mechanism 100 includes a positioning component 7 for positioning the label taking and applying part 23 at the paper outlet 304 of the label printing mechanism 300.
[0055] Specifically, the positioning assembly 7 includes a positioning rod 71 disposed on the frame 1 , a positioning portion disposed on the positioning rod 71 , and a buffer 72 disposed adjacent to the positioning rod 71 .
[0056] When the swing power module 21 drives one end of the swing arm 22 to rotate around an axis so that the swing arm 22 drives the label taking and sticking part 23 to move to the label taking position, the swing arm 22 can first contact the buffer 72 and decelerate under the damping action of the buffer 72, and then the swing arm 22 slowly moves and contacts the positioning part of the positioning rod 71, and the swing arm 22 can be blocked by the positioning part on the positioning rod 71 and limited at the label taking position.
[0057] In order to limit the swing amplitude of the swing frame 53 relative to the fixed seat 52, a limiting structure 55 is provided between the swing frame 53 and the fixed seat 52. The swing frame 53 includes two first side walls 531 arranged opposite to each other, and a second side wall 532 connected between the two first side walls 531. The limiting structure 55 includes a first limiting portion 551 provided on the first side wall 531, a first limiting matching portion 552 provided on the fixed seat 52 and matched with the first limiting portion 551, a second limiting portion 553 provided on the second side wall 532, and a second limiting matching portion 554 provided on the fixed seat 52 and matched with the second limiting portion 553. The swing amplitude of the swing frame 53 relative to the fixed seat 52 in the direction of overcoming the elastic force of the first elastic member 54 is limited by the limiting matching of the first limiting portion 551 and the first limiting matching portion 552, and the swing amplitude of the swing frame 53 relative to the fixed seat 52 in the swing direction acted upon by the elastic force of the first elastic member 54 is limited by the limiting matching of the second limiting portion 553 and the second limiting matching portion 554. This ensures that when the swing frame 53 swings relative to the fixed seat 52, the swing amplitude of the swing frame 53 in both the counterclockwise direction and the clockwise direction is limited, thereby reducing unnecessary swinging and vibration of the swing frame 53 and avoiding unnecessary collision between the swing frame 53 and the fixed seat 52.
[0058] Among them, the first limiting portion 551 can be a limiting hole or a limiting groove opened on the first side wall 531 of the swing frame 53, the first limiting matching portion 552 can be a limiting column, a limiting pin or a limiting screw installed on the fixed seat 52, the second limiting portion 553 can be a limiting baffle formed on the second side wall 532 of the swing frame 53, the second limiting portion 553 can also be a sheet metal part formed by stamping and bending the second side wall 532 of the swing frame 53, and the second limiting matching portion 554 can be a gasket or a block pasted on the side wall of the fixed seat 52, and there is no specific limitation.
[0059] The pressing assembly 5 further includes a support frame 56, which is independently arranged from the frame 1, and the fixing seat 52 is mounted on the support frame 56. In some embodiments, the pressing assembly 5 can also be mounted on the frame 1 as a whole, which is not specifically limited.
[0060] Combination Figure 4 and Figure 5 As shown, in order to make the label removal part 23 better contact and fit with the surface to be labeled of the material 201 (specifically, the front surface and side surface of the material 201), a shock absorbing component 8 is arranged between the label removal part 23 and the swing arm 22.
[0061] Specifically, the shock absorbing assembly 8 includes a shock absorbing seat 81 fixed to the swing arm 22, a guide rod 82 fixed to the label removal portion 23, and a second elastic member 83 passed through the guide rod 82 and located between the shock absorbing seat 81 and the label removal portion 23. A guide hole 811 is opened on the shock absorbing seat 81, and the guide rod 82 is movably fitted in the guide hole 811.
[0062] Combination Figure 1 and Fig. 9 As shown, the label taking and sticking portion 23 moves to the first labeling position driven by the swing arm 22 so as to apply the label to one surface of the material 201 (specifically, it can be the front surface of the material 201). When the label taking and sticking portion 23 collides and contacts with the front surface of the material 201, the guide rod 82 on the label taking and sticking portion 23 can move along the guide hole 811 of the shock absorbing seat 81, and during the movement of the guide rod 82 along the guide hole 811, the second elastic member 83 is in a state of elastic force storage, so that the relative position of the label taking and sticking portion 23 on the swing arm 22 can be adjusted, so that the label taking and sticking portion 23 can be better fitted with the front surface of the material 201, thereby improving the label application effect. The details are not repeated here.
[0063] Combination Figure 2 and Fig.10 As shown, the label taking and sticking portion 23 moves to the second labeling position driven by the swing arm 22 so as to apply the label to another surface adjacent to the material 201 (specifically, it can be the side surface of the material 201 adjacent to the front surface). When the label taking and sticking portion 23 collides and contacts the side surface of the material 201, the guide rod 82 on the label taking and sticking portion 23 can move along the guide hole 811 of the shock absorbing seat 81, and during the movement of the guide rod 82 along the guide hole 811, the second elastic member 83 is in a state of elastic force storage, so that the relative position of the label taking and sticking portion 23 on the swing arm 22 can be adjusted, so that the label taking and sticking portion 23 can better fit with the side surface of the material 201, thereby improving the label application effect. The details are not repeated here.
