Description

Technical Field

[0001] The utility model relates to the technical field of labeling machines, in particular to a negative pressure labeling device. Background Art

[0002] The labeling plate of the labeling machine on the existing packaging line is relatively short, with a length of 99mm, while the length of the label is 200mm. As a result, more than half of the labels sent by the box labeling machine will not be adsorbed on the labeling plate, which can easily cause the labels to fall off. Occasionally, the labels will be pasted off-center or wrinkled. When the back-end staff finds that the label is wrinkled, they need to tear it off and re-paste it to ensure that the scanner can recognize the QR code on the label when selling it later, resulting in low work efficiency of the back-end staff. In addition, since the labeling plate is rigidly connected to the cylinder and there is no buffer device, the impact on the box during labeling is relatively large, causing packaging quality problems.

[0003] Therefore, there is an urgent need to provide a negative pressure labeling device that can solve at least one of the above technical problems. Utility Model Content

[0004] The purpose of the utility model is to provide a negative pressure labeling device, the adsorption surface of which is of sufficient length, and can ensure that the label and the adsorption surface have better fit during the process of the box label machine sending out the label and during the labeling process, and the label state and position are more stable, effectively avoiding the phenomenon of label falling off, label deviation and wrinkles.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model provides a negative pressure labeling device, comprising a labeling mechanism and a lateral air blowing component, the labeling mechanism having an adsorption surface, the adsorption surface being configured to reciprocate along a labeling direction, the adsorption surface being provided with an adsorption port and the length of the adsorption surface being not less than the length of the label, the lateral air blowing component being spaced apart from the labeling mechanism and projected along the moving direction of the adsorption surface, the projection of the lateral air blowing component being located to the side of the projection of the adsorption surface, and the lateral air blowing component being provided with an air blowing hole for blowing air toward the adsorption surface.

[0007] Furthermore, the lateral blowing assembly comprises a blowing pipe, and the blowing pipe is provided with a plurality of the blowing holes.

[0008] Furthermore, the plurality of blowing holes include a plurality of first air holes and a plurality of second air holes that are spaced apart and distributed along the height direction of the blowing tube, and the plurality of first air holes and the plurality of second air holes are arranged one by one relatively along the circumference of the blowing tube, and each of the first air holes is used for blowing air toward one end of the adsorption surface in the length direction, and each of the second air holes is used for blowing air toward the other end of the adsorption surface in the length direction.

[0009] Furthermore, a projection of the lateral blowing assembly along the moving direction of the adsorption surface is located on a side of the adsorption surface close to the box label machine.

[0010] Furthermore, the lateral blowing assembly includes a mounting seat and a locking piece, the mounting seat has a clamping hole, the blowing pipe passes through the clamping hole and slidably cooperates with the clamping hole, the locking piece is connected to the mounting seat, and the locking piece is used to adjust the clamping state of the clamping hole.

[0011] Furthermore, the labeling mechanism includes a driving member and a labeling plate group connected to the driving member, the driving member is used to drive the labeling plate group to reciprocate along the labeling direction, and the labeling plate group has the adsorption surface.

[0012] Furthermore, the labeling plate group includes a fixed plate, a movable plate and an elastic member, the fixed plate is connected to the driving member, the movable plate slides with the fixed plate along the labeling direction, the movable plate has the adsorption surface, and the elastic member is clamped between the movable plate and the fixed plate.

[0013] Furthermore, a guide column is provided between the fixed plate and the movable plate, one of the fixed plate and the movable plate is fixedly connected to the guide column, and the other is slidably matched with the guide column, and the elastic member is sleeved on the outside of the guide column.

[0014] Furthermore, the movable plate has a main airway and a plurality of branch airways, the main airway is used to communicate with an external air source, one end of each branch airway is connected to the main airway, and the other end is the adsorption port.

[0015] Furthermore, the suction ports are configured in plurality, and the plurality of suction ports at least include a first suction port arranged corresponding to a corner of the label.

[0016] The negative pressure labeling device provided by the utility model can produce the following beneficial effects:

[0017] During the labeling process, a single label coming out of the box label machine on the side of the labeling mechanism will move from one end of the adsorption surface in the labeling mechanism to the other end of the adsorption surface. The label delivery will be stopped after the single label is in place. During the above process, the blowing holes on the side blowing assembly can blow air toward the adsorption surface to ensure that the label can be tightly attached to the adsorption surface during the box label machine delivering the label, and the label will not be wrinkled or bent. When the label delivery is about to stop, the adsorption port of the adsorption surface works to adsorb the label; then the adsorption surface moves toward the box to be labeled, and the label is attached to the box. During the above process, due to the projection along the moving direction of the adsorption surface, the projection of the side blowing assembly is located on the side of the projection of the adsorption surface, so that the side blowing assembly does not interfere with the movement of the adsorption surface; after the pasting is completed, the adsorption surface moves away from the box and resets to wait for the next label to be delivered by the labeling mechanism.

During the labeling process, the lateral blowing component can also assist the adsorption port to maintain the stability of the label state and position, thereby effectively avoiding phenomena such as label falling off, label deviation and wrinkles.

DETAILED DESCRIPTION

[0027] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0031] The first aspect of the present invention provides a negative pressure labeling device. Figures 1 to 3 As shown, it includes a labeling mechanism 1 and a lateral blowing component 2, the labeling mechanism 1 has an adsorption surface 1221, the adsorption surface 1221 is configured to move back and forth along the labeling direction, a suction port is provided on the adsorption surface 1221 and the length of the adsorption surface 1221 is not less than the length of the label, the lateral blowing component 2 is spaced apart from the labeling mechanism 1, and projected along the moving direction of the adsorption surface 1221, the projection of the lateral blowing component 2 is located on the side of the projection of the adsorption surface 1221, and the lateral blowing component 2 is provided with a blowing hole 211 for blowing air toward the adsorption surface 1221.

[0032] When the negative pressure labeling device provided in the above embodiment is used, Figure 1 Direction, box label machine ( Figure 1(not shown) will be placed on the right side of the labeling mechanism 1, and the label outlet of the box labeling machine is located on the right side of the adsorption surface 1221, such as Figure 2 As shown, a single label from the box label machine will move from the left end to the right end of the adsorption surface 1221. In this process, Figure 3 As shown, the blowing hole 211 on the blowing pipe 21 will blow air toward the adsorption surface 1221 to ensure that the label sent by the box label machine can be tightly attached to the adsorption surface 1221, and the label will not be wrinkled or bent. The adsorption port on the adsorption surface 1221 can be used in conjunction with the blowing hole 211 in the above process, or the label can be adsorbed when the box label machine is about to stop sending the label; during the labeling process, Figure 2 As shown, due to the projection along the moving direction of the adsorption surface 1221, the projection of the side blowing component 2 is located on the side of the projection of the adsorption surface 1221, so that the side blowing component 2 will not interfere with the movement of the adsorption surface 1221. The adsorption surface 1221 can drive the label along the labeling direction to approach the box to be labeled to achieve label pasting. In the above process, the side blowing component 2 can assist the adsorption surface 1221 to maintain the stability of the label state and position, and effectively avoid phenomena such as label falling off, label deviation and wrinkles.

[0033] It should be noted that the box signing machine can be an existing box signing machine, and the improvements of the above and following embodiments are not in the box signing machine, so the box signing machine is not shown in the accompanying drawings.

[0034] Specifically, the length of the adsorption surface 1221 may be 200 mm, or may be 210 mm or 220 mm which is greater than 200 mm.

[0035] In at least one embodiment, the pressure applied to the label by the blowing hole 211 is smaller than the suction force of the suction port on the label.

[0036] During the process of the box label machine delivering the label, the suction port may not absorb the label, and pressure may be applied to the label through the air hole 211, so that the label is pressed on the suction surface 1221. The purpose of this setting is: since one end of the label is suspended in the air and the other end is connected to the box label machine during the process of the box label machine delivering the label, the external force applied to the label does not need to overcome the gravity of the label, and it is only necessary to ensure that the label with a certain curvature is attached to the suction surface 1221. If the pressure or suction applied to the label is too large, it will increase the friction between the label and the suction surface 1221, so that the label cannot slide smoothly relative to the suction surface 1221, which may easily cause the label to be stuck for a short time, which is not conducive to the accurate placement of the label. If the label is soft, the following phenomenon may occur: during the stuck process, the position of the suspended end of the label relative to the suction surface 1221 remains unchanged. As the box label machine delivers the label, the other end of the label is pushed to the suction surface 1221 and is adsorbed by the suction surface 1221, which may cause the label to wrinkle.

[0037] Therefore, the blowing hole 211 can pass 0.5 bar of compressed air, and the adsorption port can adsorb the label onto the adsorption surface 1221 through a negative pressure of -0.6 bar.

[0038] In some embodiments, Figure 2 As shown, there are multiple suction ports, and the multiple suction ports at least include a first suction port 1222 arranged corresponding to the corner of the label, so that the label can be effectively adsorbed.

[0039] The number of adsorption ports can be four, six, eight, ten, twelve, fourteen, etc.

[0040] In at least one embodiment, Figure 2 As shown, there are ten adsorption ports, which are distributed in two rows, with five in each row, and the adsorption ports in the upper row and the adsorption ports in the lower row are arranged correspondingly up and down.

[0041] The lateral blowing assembly 2 is described in detail below:

[0042] In some embodiments, the lateral blowing assembly 2 includes a blowing pipe 21 , and the blowing pipe 21 may be provided with one blowing hole 211 or a plurality of blowing holes 211 .

[0043] When there is one blowing hole 211 , the blowing hole 211 may be in a long strip shape, and the length direction thereof is parallel to the axial direction of the blowing pipe 21 .

[0044] When there are multiple air holes 211, Figure 3 As shown, the plurality of blowing holes 211 are distributed at intervals along a direction parallel to the axial direction of the blowing pipe 21 .

[0045] In some other embodiments, such as Figure 4 and Figure 5 As shown, the multiple air holes 211 include a plurality of first air holes 2111 distributed at intervals along the height direction of the air blowing tube 21 and a plurality of second air holes 2112 distributed at intervals along the height direction of the air blowing tube 21. The multiple first air holes 2111 and the multiple second air holes 2112 are arranged one by one opposite to each other along the circumference of the air blowing tube 21, and the blowing directions of the first air holes 2111 and the second air holes 2112 are different.

[0046] The above arrangement enables the blowing holes 211 to blow air not only into one area of ​​the adsorption surface 1221 , thereby increasing the blowing area of ​​the blowing tube 21 , so as to apply pressure more evenly to all parts of the label.

[0047] by Figure 4 and Figure 5For example, each first air hole 2111 is used to blow air toward the left end of the adsorption surface 1221 in the length direction, and each second air hole 2112 is used to blow air toward the right end of the adsorption surface 1221 in the length direction, so as to more comprehensively apply pressure to the label on the adsorption surface 1221 during the entire process of the box label machine feeding the label.

[0048] It can be understood that the length direction of the adsorption surface 1221 is Figure 5 The left and right direction in .

[0049] Of course, in some other embodiments, the blowing directions of the blowing holes 211 on the blowing tube 21 may be different.

[0050] Specifically, the height of the air blowing pipe 21 may be 100 mm, and the diameter of the air blowing hole 211 may be 6 mm.

[0051] In some embodiments, Figure 3 As shown, the projection of the lateral blowing assembly 2 along the moving direction of the adsorption surface 1221 is located on the side of the adsorption surface 1221 close to the box label machine.

[0052] Reference Figure 5 During the label feeding process of the box label machine, the label moves from right to left on the adsorption surface 1221. The above arrangement can make the force F of the gas blown out of the blowing hole 211 in the length direction of the adsorption surface 1221 x It is also from right to left, which helps to ensure the flatness of the label and does not cause resistance to the label delivery process.

[0053] In some embodiments, Figure 5 As shown, the lateral blowing assembly 2 includes a mounting seat 22 and a locking member 23. The mounting seat 22 has a clamping hole. The blowing pipe 21 passes through the clamping hole. The locking member 23 is connected to the mounting seat 22. The locking member 23 is used to adjust the clamping state of the clamping hole.

[0054] The mounting seat 22 may include two seat bodies that are arranged opposite to each other, and a clamping hole is formed between the two seat bodies. When the locking piece 23 is disconnected from the seat body, the blowing tube 21 can slide relative to the clamping hole. After the locking piece 23 is tightened, the position of the blowing tube 21 relative to the clamping hole is locked, so that the height of the blowing tube 21 is adjustable.

[0055] In some embodiments, Figure 5 As shown, the labeling mechanism 1 includes a driving member 11 and a labeling plate group 12 connected to the driving member 11 . The driving member 11 is used to drive the labeling plate group 12 to reciprocate along the labeling direction. The labeling plate group 12 has an adsorption surface 1221 .

[0056] The driving member 11 can be arranged on the operating platform 3 , and the driving member 11 can drive the labeling plate group 12 to move back and forth along the labeling direction, so as to realize the labeling action of the labeling plate group 12 and the resetting action of the labeling plate group 12 .

[0057] The driving member 11 may be a pneumatic cylinder, a hydraulic cylinder, a linear motor, etc., and any structure that can drive the labeling plate group 12 to move back and forth along the labeling direction may be used.

[0058] In at least one embodiment, the driving member 11 is a pneumatic cylinder.

[0059] In some embodiments, Figure 5 As shown, the labeling plate group 12 includes a fixed plate 121, a movable plate 122 and an elastic member 123. The fixed plate 121 is connected to the driving member 11. The movable plate 122 slides with the fixed plate 121 along the labeling direction. The movable plate 122 has an adsorption surface 1221. The elastic member 123 is clamped between the movable plate 122 and the fixed plate 121.

[0060] When in use, the driving member 11 drives the fixed plate 121 along the labeling direction to approach the box to be labeled. Under the limitation of the elastic member 123, the movable plate 122 moves accordingly until the adsorption surface 1221 on the movable plate 122 contacts the box to be labeled. The movable plate 122 overcomes the elastic force of the elastic member 123 to squeeze the elastic member 123, which has a buffering effect on the movement of the movable plate 122, thereby avoiding a large impact of the movable plate 122 on the box during labeling, and will not cause packaging quality problems.

[0061] The elastic member 123 may be a rubber pad, a spring, etc. In at least one embodiment, the elastic member 123 is a coil spring.

[0062] In some embodiments, Figure 5 As shown, a guide column 124 is provided between the fixed plate 121 and the movable plate 122 , one of the fixed plate 121 and the movable plate 122 is fixedly connected to the guide column 124 , and the other is slidably matched with the guide column 124 , and the elastic member 123 is sleeved on the outside of the guide column 124 .

[0063] The above arrangement does not require the provision of a guide structure in which the guide groove and the slider cooperate, and is more convenient for processing the fixed plate 121 and the movable plate 122 .

[0064] In at least one embodiment, the movable plate 122 is fixedly connected to the guide post 124 , and the fixed plate 121 is slidably matched with the guide post 124 . Since an air path is provided in the movable plate 122 , the above arrangement makes it easier to process and assemble the labeling plate set 12 as a whole.

[0065] Specifically, the guide posts 124 may be configured as two, three, four or other multiple numbers.

[0066] In at least one embodiment, four guide posts 124 are provided to effectively ensure stable sliding of the movable plate 122 .

[0067] In some embodiments, Figure 6 As shown, the movable plate 122 has a main airway 1223 and a plurality of branch airways 1224 . The main airway 1223 is used to communicate with an external air source. One end of each branch airway 1224 is connected to the main airway 1223 , and the other end is a suction port.

[0068] The above arrangement allows the movable plate 122 to be connected to only one gas source, thereby effectively reducing the device cost.

[0069] It should be noted that when the adsorption port has Figure 2 When there are multiple rows as shown, there may be multiple main air passages 1223 , and the multiple main air passages 1223 are gathered at one place and communicated with an external air source.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
