Description

Technical Field

[0001] This invention relates to the field of labeling equipment technology, and more specifically to a fully automatic labeling machine for packaging bags. Background Technology

[0002] Automatic labeling machines for packaging bags are devices that affix rolls of self-adhesive labels to PCBs, products, or prescribed packaging. Label materials are generally paper or metal foil, and automatic labeling machines for packaging bags are an indispensable component of modern packaging. The variety of labeling machines produced in my country is gradually increasing, and the technological level has also greatly improved.

[0003] Existing labeling machines can complete the application of a large number of labels by machine, which can greatly reduce labor consumption. However, while ensuring quantity, quality may not be guaranteed. When applying a large number of labels at once, some labels may not be properly attached and may fall off easily, which will affect the quality of the product. Once the label falls off, the customer will not be able to obtain the information provided on the label. Summary of the Invention

[0004] To address the problem that labels sometimes fail to adhere properly when applied by current fully automatic labeling machines for packaging bags, this invention proposes a fully automatic labeling machine for packaging bags.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] This application discloses a fully automatic labeling machine for packaging bags, including a pressing block. The pressing block has an air suction hole at its top, a lifting drive device below it, and is also connected to the air suction device. Flat plates are provided on both sides of the pressing block, with the flat plates higher than the plane of the air suction hole. The air suction device communicates with the air suction hole, and a pressing panel is provided above the air suction hole. The distance between the two flat plates is greater than the distance between the two sides of the pressing panel.

[0007] The above technical solution is as follows: The present invention has flat plates on both sides of the pressing block. When the plastic packaging that needs to be labeled is transported over, it will be nested on the pressing panel. The flat plates on both sides will exert a pulling force on the plastic packaging in two directions, making the surface for labeling flatter. An air suction hole is provided on the top of the pressing block and connected to an air suction device. When pressing, the label can be sucked up and then pressed, ensuring that it can be pressed firmly in the end.

[0008] Preferably, a telescopic rod is connected to one side of the pressing panel.

[0009] Using the above technical solution: the telescopic rod on one side of the pressing plate can adjust the position of the pressing panel. For different plastic packaging, the pressing panel provided by the present invention can adapt to different positions where the label needs to be pasted.

[0010] A further preferred embodiment includes a label tape placement rod, which is connected to the first rotary drive device.

[0011] The above technical solution allows for the placement of pre-wound label tapes on the label tape placement rod, which, together with other rods, assists in the pasting of labels. It can also work in conjunction with the first infrared sensing device to achieve reverse rotation.

[0012] A further preferred embodiment includes a label tape support rod, on which a rotating sleeve is nested.

[0013] The above technical solution employs a label tape support plate to support the label tape, assist in pulling out the label tape from the label tape placement rod, and simultaneously assist the label tape collecting rod in collecting the labeled label tape. The rotating sleeve assists in the transfer of labels.

[0014] Further preferably, it also includes a first infrared sensing device and a second infrared sensing device.

[0015] Using the above technical solution: the first infrared sensing device can detect the label tape that has been pasted. When it finds that the label on the label tape is not pasted, it can send a signal to the label tape placement rod to rotate in the opposite direction, which can prevent the label from being missed when pasting.

[0016] A further preferred embodiment includes a label tape collecting rod, which is connected to a second rotary drive device.

[0017] Using the above technical solution: the second rotary drive device can drive the label tape to rotate and collect the label tape that has been applied.

[0018] A further preferred embodiment includes a handbrake switch, which is connected to the first rotary drive device and is capable of stopping the rotation of the rotary motor.

[0019] By adopting the above technical solution: when it is not necessary to affix labels, or when it is found that the label affixing has been incorrect, the handbrake can be pressed to stop the rotation of the first rotary drive device and avoid related losses.

[0020] In a further preferred embodiment, a fixing member is also provided on one side of the telescopic rod.

[0021] The above technical solution addresses the issue that the telescopic rod may deform when the panel is pressed, affecting the label's adhesion quality. The fixing component reduces the deformation of the telescopic rod, ensuring that it does not deform during pressing and guaranteeing the pressing quality.

[0022] More preferably, the first infrared sensing device is electrically connected to the first rotary drive device.

[0023] The above technical solution is adopted: the first infrared sensing device can detect the label tape after the label has been affixed. When a label is still detected, it proves that the label has not been affixed. The device will send a signal to the first rotation drive device to rotate in the opposite direction and re-affix the label, which can reduce label waste.

[0024] More preferably, the second infrared sensing device is electrically connected to the second rotary drive device and the lifting drive device.

[0025] The above technical solution is adopted: the second infrared sensing device can detect the label tape that has not yet been pasted. When the label is sensed, it sends a signal to the second rotary drive device, so that the label is rotated to the position of the pressing block and pressed, thus realizing complete automation.

[0037] Please see Figure 1 as well as Figure 3This application discloses a fully automatic labeling machine for packaging bags, including a pressing block 1. The pressing block 1 has an air suction hole 2 at its top, a lifting drive device 3 below it, and is also connected to an air suction device 4. Flat plates 15 are provided on both sides of the pressing block 1, with the flat plates 15 being higher than the plane containing the air suction hole 2. The air suction device 4 communicates with the air suction hole 2. A pressing panel 5 is provided above the air suction hole 2, and the distance between the two flat plates 15 is greater than the distance between the two sides of the pressing panel 5.

[0038] When the label tape is conveyed to the position of the pressing block 1, the pressing block 1 will press upward. There are flat plates 15 on both sides of the pressing block 1. When the pressing block 1 presses onto the pressing panel 5, since the plastic packaging is in a nearly taut state, the flat plates 15 on both sides of the pressing block 1 are higher than the plane of the pressing block 1, which will lift up both sides of the plastic packaging, making the plastic packaging completely taut. When pressing, the adhesive surface of the plastic packaging will not wrinkle. There are suction holes 2 on the pressing block 1. When the label is conveyed, the label is sucked to the top position of the pressing block 1, and then pressed towards the pressing panel 5. This can ensure better label adhesion and prevent label wrinkles during the pasting process.

[0039] For example, please refer to Figure 1 The pressing panel 5 is connected to a telescopic rod 6 on one side. The telescopic rod 6 can move forward to change the position of the pressing panel 5 to adapt to the position of the label.

[0040] For example, please refer to Figure 1 It also includes a label strip placement rod 7, which is connected to the first rotary drive device 13. The label strip placement rod 7 is used to place the label strip that has been wound by the roller. The label strip that has been wound and is to be pasted can be placed on the top of the label strip placement rod 7 to assist in pasting the label with other rods. It can also cooperate with the first infrared sensing device 10 to achieve reverse rotation.

[0041] For example, please refer to Figure 1 It also includes a label tape support rod 8, on which a rotating sleeve 9 is nested. The label tape support rod 8 can support the label tape transmitted between the label tape placement rod 7 and the label tape collection rod 11, so that the label tape passes the position of the pressing block 1 and is pressed by the pressing block 1. During the label tape transmission process, the label tape is attached to the rotating sleeve 9, which can cooperate with the rotating motor at the label tape collection rod 11 to drive the label tape.

[0042] For example, please refer to Figure 1It also includes a first infrared sensor 10 and a second infrared sensor 16. The first infrared sensor 10 can detect the label tape that has been pasted. If it finds that a label on the label tape is not pasted, it can send a signal to the label tape placement rod 7 to rotate in the opposite direction, which can prevent the label from being missed when pasting. There are marks on the labels on the label tape. When the second infrared sensor 16 detects a label, it sends a signal to the relevant motor to rotate and paste the next label.

[0043] For example, please refer to Figure 1 as well as Figure 2 It also includes a label tape collecting rod 11, which is connected to a rotating motor.

[0044] The label tape collecting rod 11 provides power for the entire label tape transmission process. The rotating motor can give the label tape collecting rod 11 a rotational force. When a label is applied, the label tape collecting rod 11 can rotate to collect the label tape with the applied label.

[0045] For example, please refer to Figure 1 as well as Figure 2 It also includes a handbrake 12, which is connected to the rotary drive device and can stop the rotation of the rotary motor. When the label tape fails to adhere, the handbrake can be pulled to stop the rotation of the rotary drive device and prevent the label tape from continuing to be transmitted in order to prevent further failures.

[0046] For example, please refer to Figure 1 A fixing member 14 is also provided on one side of the telescopic rod 6.

[0047] To adapt to the location of the label, the telescopic rod 6 can adjust the position of the pressing panel 5. When the adjustment is complete, it can be fixed by the fastener 14. During the pressing process of the pressing block 1, the pressing panel 5 will not deform backward, making the pressing more secure.

[0048] For example, please refer to Figure 1 The first infrared sensor 10 is electrically connected to the first rotary drive device. The first infrared sensor 10 is positioned at the location where the label tape is pasted and can detect the label. When the label is detected, it indicates that the label has not been pasted. The first infrared sensor 10 will send a signal to the first rotary drive device 13 connected to the label tape support rod 8 to achieve reverse rotation, which can press the label again.

[0049] For example, please refer to Figure 1The second infrared sensor 16 is electrically connected to the second rotary drive device 17 and the lifting drive device 3. The second infrared sensor 16 can sense specific marks on the label. When the label is transmitted to the position of the second infrared sensor 16, the second infrared sensor 16 can send commands to the second rotary drive device 17 and the lifting drive device 3 to transmit the label tape and for the lifting drive device 3 to press the label so that the label is attached to the product packaging.

[0050] Example: When the label is transmitted to the location of the second infrared sensor 16, the second infrared sensor 16 senses the label and sends relevant signals to the second rotary drive device 17 and the lifting drive device 3. The second rotary drive device 17 drives the label tape placement rod 7 to rotate at a certain angle, so that part of the label tape is wound into the label tape placement rod 7. At this time, the label tape on the label tape placement rod 7 also extends a certain distance, and the label on the label tape is also at the position of the pressing block 1. The air suction hole 2 sucks in air, so that the label adheres to the pressing block 1 to prevent wrinkles. The product packaging is also transported by the corresponding mechanism. When the label is pressed between the pressing block 1 and the pressing panel 5, the pressing block 1 completes the pressing. The infrared sensor continues to sense the label, and the second rotary drive device 17 continues to rotate. The label tape collecting rod 11 can collect the label tape after the label is applied, and continue to press and apply the next label. When the first infrared sensor 10 senses that there is still a label on the label tape, it will transmit a signal to the first rotary drive device 13. The first rotary drive device 13 drives the label tape support rod 8 connected to it to rotate in the opposite direction. The second infrared sensor 16 senses the label again and sends a signal to the lifting drive device 3 to realize the pressing again.

[0051] Unless otherwise specified, the equipment components involved in the above embodiments are all conventional equipment components, and the connection methods and control methods involved are all conventional connection methods and control methods unless otherwise specified.

[0052] The present invention has been described in detail above with reference to the embodiments. However, those skilled in the art will understand that, without departing from the spirit of the present invention, various specific parameters in the above embodiments can be changed to form multiple specific embodiments, all of which are common variations of the present invention, and will not be described in detail here.
