Description

TECHNICAL FIELD

[0001] The application belongs to the field of labeling and cutting equipment, and particularly relates to a labeling and cutting all-in-one machine. BACKGROUND

[0002] The labeling and cutting all-in-one machine is an automatic equipment integrating labeling and cutting functions. There is a model in the prior art, in which a cutting spindle and a label picking mechanism (including a cylinder and a suction cup) are arranged on the same cross beam, and a label feeding system is arranged on one side of the cross beam. The equipment realizes x-axis processing of the plate by the cutting spindle and picking of the label by the label picking mechanism through reciprocating movement of the cross beam. Although the cooperative operation mode improves the production efficiency to a certain extent, the overall efficiency is insufficient because the labeling and cutting need to be performed at different times. However, the model has certain advantages in cost control. However, a problem is exposed in the use process: although the spindle is provided with a dust collection system, it is still difficult to completely avoid the generation and diffusion of dust during the cutting process. Because the label picking mechanism is very close to the spindle, the dust not only pollutes the working environment, but also seriously adheres to the surface of the suction cup of the label picking mechanism and enters the air hole, which reduces the suction capacity of the suction cup, affects the stability and accuracy of label picking, and further reduces the overall operation efficiency and product quality of the equipment. Therefore, the prior art needs to be further improved and enhanced. CONTENT OF THE UTILITY MODEL

[0003] The labeling and cutting all-in-one machine provided by the utility model at least solves one or more technical problems in the prior art or at least provides a beneficial alternative.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme:

[0005] The labeling and cutting all-in-one machine comprises a cutting mechanism and a label picking mechanism, the cutting mechanism and the label picking mechanism are jointly installed on a cross beam and can synchronously move along the direction of the cross beam, the label picking mechanism comprises a first cylinder and a second cylinder, a piston rod of the first cylinder is connected with the second cylinder to drive the second cylinder to lift, a piston rod of the second cylinder is connected with a suction cup assembly, a pair of protective covers are rotationally connected to the outer side of the second cylinder, when the piston rod of the second cylinder is in a retracted state, the two protective covers are closed to form a protective space, and the suction cup assembly is located in the protective space; when the piston rod of the second cylinder is in an extended state, the suction cup assembly abuts against the inner wall of the protective cover to make the protective cover rotate and expand, and the suction cup assembly is exposed to pick up the label.

[0006] The above structure, when cutting, the protective cover is closed to form a protective space, isolating the suction cup assembly and cooperating with the dust collection system to form a double protective barrier. The rising dust contacts the outer wall of the protective cover instead of the surface of the suction cup. The protective cover can be made of a non-dust-accumulating material, effectively blocking the dust from entering the air path and the surface of the suction cup, reducing the decay rate of the suction force of the suction cup assembly, and improving the success rate of label picking. When labeling, the suction cup assembly pushes the protective cover open to pick up the label. When cutting, the second cylinder piston rod retracts to reset the protective cover, reducing the possibility of dust interference during label picking. The double-cylinder series design controls the height of the first cylinder and the expansion of the protective cover by the second cylinder, ensuring labeling accuracy.

[0007] In a preferred implementation, the piston rod of the second cylinder has a first position and a second position. When the second cylinder piston rod is in the first position, the two protective covers are closed, and the outer wall edge of the suction cup assembly abuts the inner wall of the protective cover. When the second cylinder piston rod is in the second position, the protective cover expands and the lowest point slides in contact with the side wall of the suction cup assembly.

[0008] In a preferred implementation, the second cylinder is electrically connected to the controller. The controller controls the second cylinder to keep the second cylinder piston rod in the first position during cutting, and keeps the second piston rod in the second position during label picking and labeling.

[0009] The controller precisely controls the position of the second cylinder piston rod (first position / second position), achieving intelligent control.

[0010] In a preferred implementation, the outer wall of the second cylinder is provided with a plug-in ring, and the protective cover is provided with a corresponding plug-in hole. The plug-in ring and the plug-in hole are aligned and inserted into the rotating shaft to realize the connection between the protective cover and the second cylinder.

[0011] In a preferred implementation, the center of gravity of the protective cover is located below the bottom of the cylinder barrel of the second cylinder. When the second cylinder piston rod is in the retracted state, the two protective covers can be stably closed under the action of gravity.

[0012] The center of gravity of the protective cover is designed so that when the piston rod of the second cylinder is retracted, the protective cover moves downward along the movement trajectory of the cylinder. The gravitational force is directly converted into closing pressure, without the need for external driving or locking mechanisms. Through the synergistic effect of mechanical structure and gravity, reliable closure of the protective cover can be achieved, simplifying the equipment structure and making it suitable for frequent opening and closing of automated protection scenarios.

[0013] In a preferred implementation, the edge of the suction cup assembly is provided with a rounded corner to reduce the friction between the suction cup assembly and the inner wall of the protective cover.

[0014] In a preferred implementation, a buffer rubber strip is installed on the contact surface of the two protective covers to reduce the impact force of the two protective covers.

[0015] In a preferred implementation, the crossbeam is provided with a labeling machine near one side of the label pickup mechanism.

[0016] In a preferred implementation, the protective cover is made of acrylic plate. BRIEF DESCRIPTION OF DRAWINGS

[0026] In the following, only certain exemplary embodiments are simply described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature rather than limiting.

[0027] In the description of the utility model, need understanding is, the term "center", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and so on the orientation or positional relation indicated is based on the orientation or positional relation shown in the drawing, just is for the convenience of describing the utility model and simplifying the description, and is not indicate or imply the device or element indicated must have a particular orientation, with a particular orientation structure and operation, therefore can not be understood as the restriction of the utility model. In the utility model, unless otherwise explicitly specified and limited, the first feature is "on" or "under" the second feature, and the first and second features can be in direct contact, or the first and second features can be indirectly contacted through an intermediate medium.

[0028] In the utility model, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be broadly understood, for example, it can be fixedly connected, and can also be detachably connected, or integrated; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication between two elements or the interaction relationship between two elements. However, it is noted that direct connection means that the connection between the two main bodies does not form a connection relationship through excessive structure, but is connected to form a whole only through the connecting structure. For ordinary skilled persons in the art, the specific meaning of the above terms in the utility model can be understood according to the specific situation.

[0029] In the utility model, the description such as "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can explicitly or implicitly include at least one of the features.

[0030] The utility model will be described below in conjunction with the drawings of the specification.

[0031] The specific scheme adopted is:

[0032] For example Figures 1-6The utility model provides a kind of label cutting integrated machine, including cutting mechanism 1 and label pickup mechanism 2, cutting mechanism 1 and label pickup mechanism 2 are jointly installed in crossbeam 4, can be synchronously moved along the direction of crossbeam 4, label pickup mechanism 2 includes first cylinder 20 and second cylinder 21, the piston rod of first cylinder 20 is connected second cylinder 21 can drive its lifting, the piston rod of second cylinder 21 is connected suction cup assembly 22, the outside of second cylinder 21 is rotatably connected with a pair of protective cover 23, when the piston rod of second cylinder 21 is in the state of contraction, two protective cover 23 is closed to form protective space, and suction cup assembly 22 is located in protective space;When the piston rod of second cylinder 21 is in the state of extension, suction cup assembly 22 abuts the inner wall of protective cover 23 to make protective cover 23 rotate and expand, and expose suction cup assembly 22 to suck label.

[0033] The above structure, when cutting operation, protective cover 23 is closed to form protective space, and suction cup assembly 22 is isolated, and double protective barrier is formed by cooperating with dust collection system, and dust contacts the outer wall of protective cover 23 instead of the surface of suction cup, protective cover 23 can adopt dust-accumulation-free material, effectively blocks dust from invading air path and the surface of suction cup, reduces the attenuation rate of suction force of suction cup assembly 22, and improves the success rate of label pickup. When label sticking operation, suction cup assembly 22 is pressed to automatically push open protective cover 23 to take label, and when cutting operation, the piston rod of second cylinder 21 is contracted to reset protective cover 23, reduce the possibility of dust interference in label pickup process, and the double-cylinder series connection design is used, first cylinder 20 controls height, second cylinder 21 controls the expansion of protective cover 23, to ensure label sticking accuracy.

[0034] Referring to Figures 2 to 5 The piston rod of second cylinder 21 has first position and second position, when the piston rod of second cylinder 21 is in first position, two protective cover 23 is closed, and the outer wall edge of suction cup assembly 22 abuts the inner wall of protective cover 23, when the piston rod of second cylinder 21 is in second position, protective cover 23 expands and the lowest point slides the side wall of suction cup assembly 22.

[0035] When the piston rod of second cylinder 21 is in first position (contraction state), second cylinder 21 and suction cup assembly 22 are lifted as a whole, so that the outer wall edge of suction cup assembly 22 abuts the inner wall of protective cover 23 tightly, forming a static sealing effect similar to "O-ring sealing".

[0036] When the second cylinder 21 piston rod moves to the second position (extended state), the lowest point of the protective cover 23 forms a sliding contact structure with the side wall of the suction cup assembly 22. By applying a low friction coefficient material (such as a polytetrafluoroethylene coating) to the contact surface, the sliding resistance can be significantly reduced, allowing the protective cover 23 to smoothly slide along the suction cup side wall during the retraction of the second cylinder 21 piston rod to the first position, avoiding reset failure due to mechanical interference or jamming.

[0037] Further, the second cylinder 21 is electrically connected to the controller, which controls the second cylinder 21 to keep the second cylinder 21 piston rod in the first position during the cutting operation, and to keep the second piston rod in the second position during the label taking and sticking operation. By precisely controlling the position of the second cylinder 21 piston rod (first position / second position) through the controller, the controller is electrically connected to the spindle cutting control system, which has been widely used as prior art in the field of numerical control machine tools, automatic production lines and other industrial fields. The controller is not shown in this application and can be connected to the spindle driver through a wire. The spindle driver feeds back the actual speed, position and other working state information of the spindle to the controller through the encoder interface. The controller connects the electromagnetic valve of the control cylinder to drive the cylinder piston rod to move to the specified position (such as the first position). When the spindle starts to work, the controller sends a signal to switch the electromagnetic valve, and the cylinder piston rod retracts to the first position, and the protective cover 23 is closed to avoid dust pollution. In addition, in order to ensure the accuracy of the first position and the second position, the first position can be set as the complete retraction of the second cylinder 21 piston rod, and the second position can be set as the complete extension of the second cylinder 21 piston rod.

[0038] Referring to Figure 6 The outer wall of the second cylinder 21 is provided with a plug-in ring 210, and the protective cover 23 is provided with a corresponding plug-in hole 230. The plug-in ring 210 and the plug-in hole 230 are aligned with each other and inserted into the rotating shaft to realize the connection of the protective cover 23 and the second cylinder 21. To prevent the rotating shaft from loosening due to vibration or external force during operation of the equipment, a latch structure can be added to the end of the rotating shaft to ensure the connection reliability. By using a detachable connection method, the spacing, size or shape of the plug-in hole 230 of the protective cover 23 can be adjusted for different models of cylinders and suction cup assemblies 22, so that customized design can be quickly completed.

[0039] As a preferred embodiment of the present application, the center of gravity of the protective cover 23 is located below the bottom of the cylinder barrel of the second cylinder 21, and when the piston rod of the second cylinder 21 is in the retracted state, the two protective covers 23 can be stably closed under the action of gravity. The center of gravity of the protective cover 23 is designed so that when the piston rod of the second cylinder 21 is retracted, the protective cover 23 moves downward along the movement trajectory of the cylinder, and the gravitational force is directly converted into closing pressure. Without the need for external driving or locking mechanisms, the reliable closure of the protective cover 23 can be achieved only through the synergistic effect of mechanical structure and gravity, simplifying the device structure and being suitable for automated protection scenarios that need to be frequently opened and closed.

[0040] Further, the edges of the suction cup assembly 22 are rounded, and the smooth transition of the curved surface design effectively reduces the contact friction between the suction cup assembly 22 and the inner wall of the protective cover 23 during extension, thereby reducing mechanical wear and improving smoothness of movement.

[0041] Further, in order to reduce the impact of the collision between the two protective covers 23 when closed, a buffer rubber strip is added to the closing contact surface of the protective cover 23. The rubber strip absorbs impact energy through elastic deformation, effectively reducing the direct collision force between the protective covers 23, thereby reducing mechanical wear and noise.

[0042] As a preferred embodiment of the present application, the cross beam 4 is provided with a labeling machine 3 near the label picking mechanism 2.

[0043] As a preferred embodiment of the present application, the protective cover 23 is made of acrylic plate. Compared with metal or composite materials, acrylic plate has significant cost advantage while ensuring structural strength, is suitable for mass production application, has smooth surface and is not easy to attach dust, and only needs to be wiped to restore cleanliness after long-term use, thereby reducing maintenance cost.

[0044] The parts not described in the present application can be realized by using or referring to the existing technology.

[0045] The above is only a specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of various changes or replacements within the technical range disclosed by the present application, and these should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
