Description

Technical Field

[0001] The utility model relates to the technical field of labeling equipment, in particular to a labeling machine with a rotating suction nozzle. Background Art

[0002] The labeling machine is a very common automated device used to transfer labels from a label tape to a target product. Existing labeling machines usually use a fixed suction nozzle to absorb the label peeled off by the label peeling mechanism, and complete the labeling in the following ways:

[0003] First, after the suction nozzle absorbs the label peeled off by the label peeling mechanism, the label peeling mechanism moves backward, so that the label tape paper after the label is peeled off escapes from the suction nozzle range.

[0004] Then, the suction nozzle moves downward so that the adsorbed label is pressed onto the target product.

[0005] Then, the suction nozzle releases adsorption and moves upward to its original position.

[0006] Finally, the label peeling mechanism returns to its original position and peels off the next label.

[0007] It can be seen that the existing labeling machine requires the precise coordination of the label peeling mechanism and the suction nozzle to complete a labeling action, and the continuous reciprocating movement of the label peeling mechanism will cause the label tape to be continuously stretched and retracted, making it easy for the label paper to be broken during stretching or to fall off the guide wheel during retraction. When the above problems occur, the machine needs to be stopped and the label tape needs to be adjusted manually, which affects the continuous labeling action of the labeling machine. Utility Model Content

[0008] In order to solve the shortcomings of the prior art, the utility model provides a labeling machine with a rotating suction nozzle, including a labeling machine, a label tape disk, a rotating suction nozzle and a control system. The label tape is rotatably mounted on the label tape disk, one end of the label tape extends into the labeling machine and is guided by the labeling machine to peel off the label. The rotating suction nozzle absorbs the label peeled off by the labeling machine and then sticks it on the target object.

[0009] The labeling machine is provided with a first guide wheel, which is driven to rotate by the third driving mechanism, and the label tape is pulled to the label peeling mechanism, and the label peeling mechanism peels the label from the label tape. After the label is peeled off, the label tape paper is guided by the second guide wheel and then enters the recovery wheel. The recovery wheel is driven to rotate by the first driving mechanism.

[0010] The rotating suction nozzle comprises: a rotating disk driven to rotate by a second driving mechanism, and a plurality of suction nozzles are arranged at equal intervals on the side edge of the rotating disk. The suction nozzle is arranged to face the label to be peeled off when rotating to the label peeling mechanism.

[0011] The suction nozzle comprises: a suction sheet with a plurality of small through holes, and the side of the suction sheet facing away from the label is connected with the suction pipe of the micro vacuum machine through an airtight connecting pipe.

[0012] The first driving mechanism, the second driving mechanism, the third driving mechanism, the micro vacuum machine and the control system are connected by signal.

[0013] Furthermore, a stabilizing mechanism is provided between the first guide wheel and the inlet end of the label peeling mechanism. The stabilizing mechanism is provided with a flat channel wider than the label tape, and the stabilizing mechanism is provided with a plurality of roller columns pressing against the surface of the label tape at the upper and lower surfaces of the label tape inside the flat channel.

[0014] Furthermore, the inlet end of the flat channel is wider than the outlet end, and the inlet end of the flat channel faces the first guide wheel.

[0015] Furthermore, after the label tape paper is rotated out from the outlet end of the label peeling mechanism, it enters the second guide wheel through the guidance of the elastic traction mechanism.

[0016] Furthermore, the elastic traction mechanism includes a third guide wheel. The label paper enters the second guide wheel after being guided by the third guide wheel.

[0017] The two ends of the rotating shaft of the third guide wheel are rotatably connected with a slider. The two sliders are respectively sleeved on the sliding shaft, and the sliding shaft is horizontally arranged along the transmission direction of the label tape. The slider is controlled by a control mechanism to slide along the sliding shaft.

[0018] Furthermore, the control mechanism is an electric telescopic device.

[0019] Furthermore, the control mechanism includes baffles fixed at both ends of the sliding shaft, and the sliding block is connected to the baffle on one side through a first compression spring, and is connected to the baffle on the other side through a second compression spring.

[0020] Furthermore, the adsorption sheet and the airtight connection tube are connected via an airtight elastic tube. The distance L1 between the adsorption sheet and the surface of the target object satisfies: L3<L1<L2, where L2 is the length L2 of the elastic tube when it is not compressed, and L3 is the minimum length of the elastic tube after it is compressed.

[0021] Furthermore, the rotating disk is provided with an electric slip ring along the rotating shaft, the electric slip ring is sleeved with an electrically connected sliding sleeve, the sliding sleeve is electrically connected to the micro vacuum machine, and the electric slip ring is an insulating ring segment at a position corresponding to the target object.

[0022] Furthermore, the label tape is introduced into the labeling machine through a fourth guide wheel arranged outside the labeling machine.

[0023] The beneficial effect of the utility model is that the utility model performs label adsorption and labeling actions through the continuously rotating suction nozzle, and the label peeling mechanism no longer performs corresponding reciprocating actions, thereby avoiding intermittent stretching and retraction forces received by the label belt, but maintaining a fixed traction force, so that the label belt is not easy to break and is not easy to fall off from the guide wheel, which significantly improves the stability of continuous labeling of the labeling machine.

DETAILED DESCRIPTION

[0033] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0034] Please note that the terms "above", "below", "left", "right", "top", "top", "bottom", "bottom", etc. used in the present invention to describe the positional relationship do not represent the absolute positional relationship between the modules / components / assemblies / components / parts, but the relative positional relationship between the modules / components / assemblies / components / parts.

[0035] Example 1

[0036] A labeling machine with a rotating suction nozzle, such as Figure 1 As shown, it includes a labeling machine 1, a label reel 2, a rotating suction nozzle 6 and a control system. The label reel 2 is rotatably mounted with a label tape 3, one end of which extends into the labeling machine 1 and is guided by the labeling machine 1 to peel off the label. The rotating suction nozzle 6 absorbs the label peeled off by the labeling machine 1 and then sticks it on the target object 7.

[0037] The labeling machine 1 is provided with a first guide wheel 101, which is driven to rotate by the third driving mechanism, and pulls the label tape 3 to the label peeling mechanism 103, and the label peeling mechanism 103 peels the label from the label tape 3. The label tape paper 106 after the label is peeled off is guided by the second guide wheel 107 and enters the recovery wheel 105. The recovery wheel 105 is driven to rotate by the first driving mechanism.

[0038] like Figure 4 and Figure 5 As shown, the rotating suction nozzle 6 comprises: a rotating disk 601 driven to rotate by a second driving mechanism, and a plurality of suction nozzles 602 are arranged at equal intervals on the side edge of the rotating disk 601. The suction nozzles 602 are arranged to face the label to be peeled when rotating to the label peeling mechanism 103.

[0039] The suction nozzle 602 includes: a suction sheet 6021 with a plurality of small through holes, and the side of the suction sheet 6021 facing away from the label is connected to the suction pipe 6024 of the micro vacuum machine 6025 through an airtight connecting pipe 6023.

[0040] The first drive mechanism, the second drive mechanism, the third drive mechanism, and the micro vacuum machine 6025 are connected to the control system signal. The control system can be a PLC control system, a microprocessor controller, or a host controller as needed. The first drive mechanism, the second drive mechanism, and the third drive mechanism can be a servo motor or a stepper motor as needed.

[0041] The working principle of the device is as follows: first, the label tape 3 to be labeled is installed on the label tape reel 2, and a label tape 3 is led out. After being guided by the first guide wheel 101, the led label tape 3 enters the tip surface of the label peeling mechanism 103 from the flat surface of the label peeling mechanism 103, and the label and the label tape are peeled off from each other at the tip surface of the label peeling mechanism 103. After the label is peeled off, the label tape paper 106 is guided by the second guide wheel 107 along the inclined surface of the label peeling mechanism 103 and then rolled up by the recovery wheel 105. At this time, the recovery wheel 105 is continuously driven to rotate by the first driving mechanism, so that the label tape 3 can be driven to continuously move from the label tape reel 2 to the label peeling mechanism 103. After the label is peeled off, the label tape paper 106 is rolled up by the recovery wheel 105. At the same time, the rotating disk 601 driven by the second driving mechanism continues to rotate, and the rotating speed of the rotating disk 601 satisfies the rotation speed of the suction nozzle 602 and the speed of the label peeling mechanism 103 to peel the label, so that when each suction nozzle 602 rotates to the tip of the label peeling mechanism 103, a new label is passing through the tip of the label peeling mechanism 103, so that under the force of the sharp bend of the label tape 106 and the vacuum suction of the suction nozzle 602, the label can be guaranteed to be peeled off and adsorbed on the adsorption sheet 6021 of the suction nozzle 602 and rotate with the rotating disk 601 to the labeling location of the target object 7. At this time, the micro vacuum machine 6025 stops, so that the suction nozzle 602 no longer provides vacuum adsorption force to the label, so that under the action of the label's own adhesive, the label is attached to the labeling location of the target object 7 to complete the labeling.

[0042] The utility model performs label adsorption and labeling actions by a continuously rotating suction nozzle, and the label peeling mechanism no longer performs corresponding reciprocating actions, thereby avoiding intermittent stretching and retraction forces received by the label belt, and instead maintains a fixed traction force, so that the label belt is not easy to break and is not easy to fall off from the guide wheel, which significantly improves the stability of continuous labeling of the labeling machine.

[0043] Example 2

[0044] Based on the labeling machine with a rotating nozzle in Example 1, Figures 1 to 3 As shown, a stabilizing mechanism 102 is provided between the first guide wheel 101 and the inlet end of the label peeling mechanism 103. The stabilizing mechanism 102 is provided with a flat channel 1021 wider than the label tape 3, and the stabilizing mechanism 102 is provided with a plurality of roller columns 1022 pressed against the surface of the label tape 3 at the upper and lower surfaces of the label tape 3 inside the flat channel 1021.

[0045] The inlet end of the flat channel 1021 is wider than the outlet end, and the inlet end of the flat channel 1021 faces the first guide wheel 101 .

[0046] The added stabilizing mechanism 102 can make the label tape 3 enter the label peeling mechanism 103 in a fixed position through the gradually narrowing side walls and a plurality of roller columns 1022 respectively arranged on the upper and lower surfaces of the label tape 3 to press against the surface of the label tape 3, thereby making the position of the peeled label more stable, which is conducive to matching the position of the suction nozzle 602 with the label.

[0047] Example 3

[0048] Based on the labeling machine with a rotating nozzle in Example 1, Figure 1 As shown, after the label tape 106 is rotated out from the outlet end of the label peeling mechanism 103 , it enters the second guide wheel 107 through the guidance of the elastic traction mechanism 104 .

[0049] like Figure 7 and Figure 8 As shown, the elastic traction mechanism 104 includes a third guide wheel 1041. The label paper 106 enters the second guide wheel 107 after being guided by the third guide wheel 1041.

[0050] The two ends of the rotating shaft 1042 of the third guide wheel 1041 are rotatably connected with a slider 1043. The two sliders 1043 are respectively sleeved on the sliding shaft 1044, and the sliding shaft 1044 is horizontally arranged along the transmission direction of the label paper 106. The slider 1043 is controlled by the control mechanism to slide along the sliding shaft 1044.

[0051] The utility model mainly provides traction force for the label tape 3 and the label paper 106 by the rotation speed difference between the first guide wheel 101 and the recovery wheel 105. However, during operation, the traction force may change due to the slip of the label tape 3 relative to the first guide wheel 101. At this time, the traction force can be adjusted in time by the elastic traction mechanism 104, so that the traction force on the label tape 3 and the label paper 106 is maintained within an appropriate range.

[0052] According to an embodiment of the utility model, the control mechanism is an electric telescopic device. This setting can adjust the distance between the third guide wheel 1041 and the label peeling mechanism 103 by controlling the telescopic action of the electric telescopic device as needed, so that when the traction force is insufficient, additional pulling force is provided by increasing the distance between the third guide wheel 1041 and the label peeling mechanism 103, the traction force is temporarily increased, and then the distance between the third guide wheel 1041 and the label peeling mechanism 103 is adjusted back to restore the traction force. When the traction force is too high, the pulling force is reduced by decreasing the distance between the third guide wheel 1041 and the label peeling mechanism 103, the traction force is temporarily reduced, and then the distance between the third guide wheel 1041 and the label peeling mechanism 103 is adjusted back to restore the traction force.

[0053] According to one embodiment of the utility model, Figure 7 and Figure 8 As shown, the control mechanism includes: baffles 1045 fixed at both ends of the sliding shaft 1044, and the slider 1043 is connected to the baffle 1045 on one side through a first compression spring 1046, and is connected to the baffle 1045 on the other side through a second compression spring 1047. This setting offsets the traction provided by the pressure difference provided by the first compression spring 1046 and the second compression spring 1047, so that the slider 1043 drives the third guide wheel 1041 to maintain a force balance position. When the traction force changes, the force on the slider 1043 will be unbalanced and displaced. At this time, the first compression spring 1046 and the second compression spring 1047 will provide a reverse force to make the slider 1043 tend to return to the original force balance position, that is, the first compression spring 1046 and the second compression spring 1047 provide a reverse force to balance the change of traction force, so that the total value of the traction force on the label tape 3 and the label tape paper 106 is maintained within a suitable range. After the traction force is restored, the first compression spring 1046 and the second compression spring 1047 will drive the slider 1043 to return to the original force balance position.

[0054] Example 4

[0055] Based on the labeling machine with a rotating nozzle in Example 1, Figure 4 and Figure 5 As shown, the adsorption sheet 6021 and the airtight connection tube 6023 are connected through an airtight elastic tube 6022. The distance L1 between the adsorption sheet 6021 and the surface of the target 7 satisfies: L3<L1<L2, where L2 is the length L2 of the elastic tube 6022 when it is not compressed, and L3 is the minimum length of the elastic tube 6022 after it is compressed.

[0056] This arrangement allows the suction sheet 6021 to move to the surface of the target object 7, and the surface of the target object 7 presses against the suction sheet 6021, causing the elastic tube 6022 to contract, so that the elastic tube 6022 provides rebound pressure, so that the label can be tightly pressed on the surface of the target object 7, so that the label can be attached more stably. When the suction sheet 6021 leaves the surface of the target object 7, the elastic tube 6022 rebounds, so that the suction sheet 6021 returns to its original position, so that when the suction sheet 6021 moves to the label peeling mechanism 103, it is located at the designed position for adsorbing the label, so that the label can be stably adsorbed.

[0057] Example 5

[0058] Based on the labeling machine with a rotating nozzle in Example 1, Figure 6 As shown, the rotating disk 601 is provided with an electric slip ring 6011 along the rotating shaft, and the electric slip ring 6011 is sleeved with an electrically connected sliding sleeve 6012, and the sliding sleeve 6012 is electrically connected to the micro vacuum machine 6025. The electric slip ring 6011 is provided with an insulating ring segment 6013 at a position corresponding to the target 7.

[0059] This arrangement allows the micro vacuum machine 6025 to continue receiving power and maintain the attraction to the label while rotating with the rotating disk 601. At the same time, at the corresponding position of the target object 7, due to the insulating ring segment 6013, the micro vacuum machine 6025 is powered off and stops vacuuming, so that the label can be smoothly separated from the suction nozzle 602 and attached to the surface of the target object 7.

[0060] According to one embodiment of the utility model, Figure 1 As shown, the label tape 3 is introduced into the labeling machine 1 through the fourth guide wheel 4 arranged outside the labeling machine 1. This arrangement allows the label tape 3 to have an observable movement section before entering the labeling machine 1, so that it is convenient for the staff to check whether there are still labels on the label tape 3, that is, whether the label tape 3 has moved to the end section. If so, a new label tape 3 needs to be replaced.

[0061] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
