Sleeve labeling machine with feeding adjustment

Abstract

A sleeve labeling machine with feeding adjustment is mainly characterized in that an angle adjustment device is disposed on a machine platform. The angle adjustment device is capable of simultaneously adjusting an inclined angle of a feeding device, a sleeve labeling device, and a heating device of the sleeve labeling machine instead of executing a conventional horizontal feeding manner whereby the inclined angle of the feeding device can be varied according to needs. Thus, the machine is applicable to feed objects with different shapes, sizes, and volumes. The varied angles of the feeding objects assist in facilitating a sleeving operation of a shrinkage film of the sleeve labeling device and effectively improving the production efficiency.

Description

[Technical Field]

[0001] This invention relates to a feeding design for objects to be labeled, and in particular to an adjustable feeding labeling machine. [Previous Technology]

[0002] It is found that after the product is manufactured, in order to avoid damage caused by collisions during transportation, a shrink film is wrapped around the product to protect its appearance. However, in the early days, the labeling operation of the shrink film was carried out manually, which was not only time-consuming and labor-intensive, but also made it impossible to effectively control the quality.

[0003] In view of this, an automated labeling machine has been developed: As shown in Figure 1, the labeling machine 1 includes a machine base 11, a feeding device 12 disposed on the machine base 11, a labeling device 13 disposed on the machine base 11 and located on the side of the feeding device 12, and a heating device 14 located at the output end of the feeding device 12; wherein, the labeling device 13 has a central column 131 for covering the shrink film b (shown as a dashed line in the figure), a label feeding roller 132 and a label pulling roller 133 disposed on the side of the central column 131, and a cutting unit 134 for cutting the shrink film b, and the aforementioned shrink film b is cut by the cutting unit 134 after being output by the label feeding roller 132 and the label pulling roller 133; in addition, the feeding device 12 has a conveyor belt 121 disposed on the side of the central column 131, and a plurality of conveyor belts 121. The aforementioned support seats 122 are arranged at intervals, each of which can be used to place the object a to be labeled. The objects a to be labeled are sequentially fed and conveyed by the conveyor belt 121, and each object a to be labeled is covered by the shrink film b. The heating device 14 is provided on the conveyor belt 121, and the heating device 14 can heat the shrink film b on each object a to be labeled at a high temperature. Thus, each object a to be labeled is fed and conveyed by the conveyor belt 121 to the corresponding center column 131. The shrink film b is then instantly covered on the object a after being output by the label feeding wheel 132 and the label pulling wheel 133. Then it is cut by the cutting unit 134 and then conveyed by the conveyor belt 121 through the heating device 14 for high temperature heating, so that the shrink film b shrinks and adheres tightly to the object a, thereby completing the labeling operation.

[0004] However, the feeding device 12 of the conventional labeling machine 1 adopts a horizontal feeding method, that is, the object a to be labeled is fed horizontally, and then the shrink film b is injected by the labeling device 13 so that the shrink film b is sleeved on the object a, so as to facilitate the subsequent heating device 14 to perform heating and shrinking operations; however, in actual use, it was found that the object a to be labeled is fed horizontally, so there is no problem in performing labeling operations on the object a in general, but for the object a to be labeled is When the items are of different shapes, sizes, and volumes, it is necessary to use a different size labeling machine. For example, if the item to be labeled, 'a', is too heavy, the labeling device 13 cannot smoothly apply the shrink film 'b' to the item to be labeled, meaning that the shrink film 'b' is affected by the weight of the item 'a' during the application process. The shrink film 'b' cannot support the item 'a' during the application process, causing the shrink film 'b' to be easily obstructed. Therefore, poorly applied shrink film 'a' can easily affect production efficiency and needs to be improved. [Summary of the Invention]

[0005] Therefore, the purpose of this invention is to provide an adjustable feeding labeling machine that can be adjusted at different angles according to the characteristics of different objects to be labeled, so that the shrink film can be applied more smoothly when the object is being labeled, thereby effectively improving production efficiency.

[0006] Therefore, the adjustable feeding labeling machine of the present invention has an angle adjustment device disposed on the labeling machine, which includes a machine base extending outward with a horizontal reference line, and a feeding device, a labeling device, and a heating device respectively disposed on the machine base. The angle adjustment device has an actuating plate, an adjustment group, and a power actuator. The actuating plate has a top surface for the feeding device, the labeling device, and the heating device, and a bottom surface opposite to the top surface and corresponding to the machine base. An imaginary line extends outward from the bottom surface. The adjustment group is disposed between the machine base and the bottom surface, so that the actuating plate can be controlled by the adjustment group to swing between itself and the machine base, so that the imaginary line can be parallel to the reference line. Alternatively, the device can be set at an inclined angle. Furthermore, one end of the power actuator is connected to the machine base, while the other end pushes the feeding device, the labeling device, and the heating device fixed on the actuating plate to move synchronously. Therefore, the power actuator can adjust the inclination angle of the feeding device, the labeling device, and the heating device on the actuating plate in a synchronous mode. When feeding objects of different shapes, sizes, and volumes, different angle changes can be presented according to the required operation mode, making the shrink film application of the labeling device smoother. Therefore, the labeling operation is no longer just carried out in a single horizontal feeding mode, so that different angles can be adjusted according to the characteristics of different objects to be labeled, effectively improving production efficiency.

Implementation Method

[0007] The foregoing description and other technical contents, features and effects of the present invention will become clear in the following detailed description of the preferred embodiments with reference to the accompanying drawings.

[0008] Referring to Figure 2, a preferred embodiment of the adjustable feeding labeling machine of the present invention includes a machine base 31 extending outward with a horizontal baseline, and a feeding device 32, a labeling device 33, and a heating device 34 respectively disposed on the machine base 31; wherein, the labeling device 33 has a central column 331 for covering shrink film B (shown as dashed line in the figure), a label feeding roller 332 and a label pulling roller 333 disposed on the side of the central column 331, and a cutting blade 334 for cutting the shrink film B, and the aforementioned shrink film B is cut by the cutting blade 334 after being output by the label feeding roller 332 and the label pulling roller 333. In addition, the feeding device 32 has a component disposed on the central column 331. A conveyor belt 321 is provided on one side. A plurality of spaced-apart support seats 322 are formed on the conveyor belt 321, and a guide unit 323 is located on one side of the conveyor belt 321. Each support seat 322 can be used to place an object A to be labeled. The conveyor belt 321 feeds each object A to be labeled in sequence. The guide unit 323 can cooperate with the conveyor belt 321 to assist in guiding the fed object A to be labeled. At the same time, each object A to be labeled is covered by a shrink film B. Furthermore, a heating device 34 is located at the conveying end of the conveyor belt 321, and the heating device 34 can heat the object A covered with the shrink film B at a high temperature so that the shrink film B can quickly shrink and stick tightly to the object A.

[0009] Continuing from the foregoing, in particular, an angle adjustment device 4 is further provided on the machine base 31. The angle adjustment device 4 has an actuating plate 41, an adjustment assembly 42, and a power actuator 43. The actuating plate 41 has a top surface 41a for positioning the feeding device 32, the labeling device 33, and the heating device 34, a bottom surface 41b opposite to the top surface 41a and corresponding to the machine base 31, and a [missing information - likely a type of actuation device] disposed on the top surface 41a. A sliding seat 41c is provided on which the labeling device 33 is mounted, allowing the labeling device 33 to slide on the actuating plate 41. An imaginary line 41d extends outward from the aforementioned bottom surface 41b. Furthermore, an adjustment assembly 42 is located between the machine base 31 and the bottom surface 41b. The adjustment assembly 42 has a plurality of positioning protrusions 421, a plurality of positioning recesses 422, and a shaft 423. The positioning protrusions 421 are spaced apart on the bottom surface 41b. Positioning recesses 422 are spaced apart on the machine base 31 and correspond to positioning protrusions 421. The positioning recesses 422 are fitted into the positioning protrusions 421. Each positioning protrusion 421 and each positioning recess 422 is provided with a through hole D, through which the shaft 423 passes, so that the positioning protrusions 421 and positioning recesses 422 cannot be separated. This allows the actuating plate 41 to swing relative to the machine base 31 by the adjustment group 42. The imaginary line 41d can be set parallel to the reference line 31a without inclination C1 (as shown in Figure 3), or it can swing at an inclination angle. The inclination angle can be set as a first inclination C2 with an inclination of at least 45 degrees (as shown in Figure 4), or as a second inclination C3 with an inclination of at least 60 degrees (as shown in Figure 5). In this way, the inclination angle can be adjusted appropriately according to the characteristics and operational requirements of different specifications and sizes.

[0010] Furthermore, one end of the power actuator 43 is connected to the machine base 31, while the other end pushes the feeding device 32, the labeling device 33 and the heating device 34 fixed on the actuation plate 41 to move synchronously, so that by the extension and retraction of the power actuator 43, the feeding device 32 can be adjusted flexibly according to the needs of the labeling operation so that the feeding device 32 can present a corresponding tilt angle as needed. At the same time, the power actuator 43 is set in a controlled pneumatic extension and retraction mode.

[0011] Referring to Figure 2, before performing the labeling operation, the shape, size, and volume of the object A to be labeled are first observed. The heating temperature of the heating device 34, the conveying speed of the conveyor belt 321 carrying the object A, and the speed and expansion of the labeling device 33 when outputting the shrink film B are then adjusted to correspond to the conveying speed of the conveyor belt 321. The angle adjustment device 4 is then used to adjust the inclination angle of the feeding device 32, the labeling device 33, and the heating device 34 on the actuating plate 41 to a better labeling operation angle according to the actual shape of the object A. After setting and adjusting in this way, the labeling operation of objects A of different sizes can be performed. The following description only takes small, medium, and large volume objects A to be labeled as examples.

[0012] Therefore, referring to Figure 3, when labeling a small object A, since the object A is small in size and light in weight, there is no need to control the power pusher 43 to extend the actuating plate 41. At this time, the imaginary line 41d extending outward from the bottom surface 41b is parallel to the baseline 31a of the machine tool 31 and is set without inclination C1, so that the labeling machine 3 can be presented in a single horizontal feeding form. Therefore, during operation, the conveyor belt 321 feeds the objects A to be labeled, which are placed on the support seats 322, one by one, so that each object A to be labeled is fed to the position corresponding to the central column 331. At this moment, the shrink film B, which is fitted onto the central column 331, will immediately expand outward rapidly under the synchronous output of the label feeding roller 332 and the label pulling roller 333, simultaneously supporting the object. This allows the shrink film B to be immediately fitted onto the object A. Then, the cutting unit 334 cuts the shrink film B at the point where it does not expand further. After that, the labeling and wrapping operation of another object A to be labeled can continue. The object A, after being wrapped with the shrink film B, will be continuously conveyed by the conveyor belt 321 and enter the heating device 34. Under the high temperature heating, the shrink film will quickly shrink and adhere tightly to the entire object A. In this way, the labeling and wrapping operation of the relatively small object A is completed.

[0013] Referring to Figures 2 and 4, when performing the labeling and wrapping operation on a medium-volume object A, because the object A is slightly larger and heavier, if only a general horizontal labeling operation is performed, the shrink film B will be unable to effectively support the object A at the moment of output due to the size and weight of the object A. Therefore, the shrink film B cannot be slipped on. Before the operation, the power pusher 43 is controlled to extend. The actuating plate 41 will then be pushed by the extension of the power pusher 43, and the actuating plate 41 will be moved through the fixed... The positioning protrusion 421 rotates around the pivot 423 as its central fulcrum and corresponds to the positioning recess 422. When the power pusher 43 extends and pushes to the set control state, the actuating plate 41 swings to an inclined angle, so that the imaginary line 41d extending outward from the bottom surface 41b corresponds to the baseline 31a of the machine tool 31 and has a first inclination C2 of at least 45 degrees. During the process of the power pusher 43 pushing the actuating plate 41, the labeling device 33 also slides appropriately on the actuating plate 41 through the sliding seat 41c to adapt to the situation. When the labeling operation mode between the labeling device 33 and the conveyor belt 321 is adjusted, and the actuating plate 41 is inclined at a 45-degree angle with the reference line 31a of the machine platform 31 as a reference, the center of gravity of each item A to be labeled placed on the support 322 will shift backward. The guide unit 323 located on one side of the conveyor belt 321 will then engage to stop the item A to be labeled placed on the support 322, ensuring that each item A to be labeled remains stably placed in the support 322 even when being fed at an inclined angle, without any impact. If the object A falls off or shifts, and its weight does not excessively press on the support 322, then when the object A to be labeled is fed to the predetermined labeling position, the shrink film B can quickly support the object A and be slipped on it under the auxiliary guide of the guide unit 323 (as shown in Figure 6A). Subsequently, after the cutter unit 334 cuts the unexpanded shrink film B, the object A will be continuously conveyed and heated by the high temperature of the heating device 34, causing the shrink film B to quickly shrink and adhere tightly to the entire object A. In this way, the labeling operation of the medium-sized object A is completed.

[0014] Referring to Figures 2 and 5, when labeling a large-volume object A, because the object A is not only large in size but also heavy, if the labeling operation mode for a medium-volume object A is used, the shrink film B will not be able to support the object A at the moment of output due to the large size and heavy weight of the object A. Therefore, before the operation, based on the first inclination C2 originally set by the actuating plate 41, the power pusher 43 then... The control drive extends the actuating plate 41 outwards again, at which point the inclination of the actuating plate 41 is further converted to a second inclination C3 of at least 60 degrees. The labeling device 33 also slides appropriately on the actuating plate 41 via the sliding seat 41c during the process of the power pusher 43 pushing the actuating plate 41. Thus, when a large object A to be labeled is placed on the support 322 and transported, its weight will be affected by the inclination of the actuating plate 41. The object A to be labeled is transferred, so that it will not be excessively pressed on the support 322. This allows the object A, in its tilted position, to be quickly supported by the output shrink film B, resulting in the shrink film B completely covering and encasing the object (as shown in Figure 6B). Then, it is further heated by the high temperature of the heating device 34, causing the shrink film B to quickly shrink and adhere tightly to the entire object A. This completes the labeling operation for the large-volume object A. Therefore, the present invention, through the angle adjustment device 4 on the machine 31, can target... The simultaneous adjustment of the tilt angles of the feeding device 32, the labeling device 33, and the heating device 34 allows the labeling machine 3 to be more than just a horizontal feeding and conveying type. It can be used to label objects A of different shapes, sizes, and volumes without changing to different specifications and sizes of labeling machines. The different angles allow the shrink film B of the labeling device 33 to be wrapped more smoothly, effectively improving production efficiency and operational convenience.

[0015] In summary, the adjustable feeding labeling machine of the present invention, by adding an angle adjustment device to the machine base, allows for simultaneous adjustment of the tilt angle of the feeding device, labeling device, and heating device on the labeling machine. This facilitates different angle changes for the objects to be labeled, making it applicable to feeding objects of different shapes, sizes, and volumes. This means that the feeding mode of the labeling operation is not limited to a single horizontal mode. Therefore, the feeding device can be made to present different tilt angles as needed, so that the shrink film application of the labeling device is smoother when the objects to be labeled are being labeled, effectively improving production efficiency.
