LABELING MACHINE WITH IMPROVED PRINTING AND APPLICATION HEAD CONNECTION MECHANISM.

Abstract

The invention relates to a head mounting mechanism used in labeling machines with printing and application functions. Specifically, the invention encompasses an improved mounting arrangement for connecting the printing and application head to a head carrier block (4.3). In the current art, the distance (x) and angular positioning between the head and the carrier structure cause moment generation on the mounting axis, and this results in wear and play in shaft-bushing based connections. In this invention, the moment arm is reduced by decreasing this distance (x), and the connection is formed by at least two bearings (4.1) aligned on the same axis on a mounting shaft (4.2). This structure provides rolling contact bearing in the mounting area and is designed to limit wear and play in the mounting elements.The invention offers a solution for enabling the printing and application head mechanism to operate with a more stable connection structure.

1 TARIFF IMPROVED PRINTING AND APPLICATION HEAD CONNECTION MECHANISM OWNER LABELING MACHINE TECHNICAL AREA 5 The invention relates to printing and application systems used in industrial production and packaging lines. This relates to (print & apply) labeling machines, specifically regarding printing and application. improved connection arrangement for attaching the head to the carrier mechanism It is related. PREVIOUS TECHNIQUE In conventional technology, this refers to labeling with a print and apply function. in the machines, the connection of the print and application head to the carrier mechanism. This is generally achieved through shaft-bushing based bearing structures. In these structures, The geometric positioning of the print head relative to the carrier structure is often entirely 15° It is non-linear, and due to assembly and compact design requirements in particular, it has a specific design. It is regulated by the angular position difference. This angular positioning is the pressure. the center of gravity of the head is positioned offset from the axis of connection This causes moment on the connection axis during operation. This leads to its formation. 20 This moment effect causes the print and application head to move up and down in each cycle. It creates repeated loads during its movement, especially on the shaft-bushing. It accelerates friction-induced wear on contact surfaces. Bushing bearing In their structures, friction is a natural consequence of surface contact-based operation. the relatively high coefficient and performance depending on lubrication conditions 25 Variability further increases this wear process. Over time, between the shaft and the bushing... The resulting wear causes gaps to form in the connection area; this The gap negatively affects the positional stability of the print and application head. It has an effect. These types of gap formations occur especially during printing, between the print head and the silicone print roller 30 the inability to maintain parallelism between them, the uniform distribution of the pressure force across the surface This prevents the transfer of information and consequently reduces print quality. Furthermore, 2 Due to mechanical gaps, vibrations and deflections increase in the system, which affects both This reduces the repeatability of printing and also mechanically during long-term use. This shortens the lifespan of the components. For these reasons, within the scope of known technology... The head mounting mechanisms used are shaft-bushing based and have angular positioning. Insufficient for applications requiring high precision and long-term stable operation. 5 It remains. Within the framework of the disadvantages arising from the known technique described above, The technical problem that the invention aims to solve is the carrier of the print and application head. reducing the moment effect resulting from the connection to the mechanism, this moment 10 friction-related issues occurring in fasteners depending on the effect prevention of wear and tear and the resulting mechanical gaps It is to prevent. Another technical problem that is targeted to be solved within this scope is printing and Maintaining the positional stability of the application head throughout its operation, pressure on the head. Maintaining sustainable parallelism between the rolls and thus ensuring print quality 15 The quality can be maintained consistently over a long period of time. Also, mechanical connection. to limit wear and void formation occurring in the elements by restructuring the system, the need for maintenance is reduced and its service life is extended. Increasing the number of participants is also among the technical problems that are intended to be solved. In addition, during the dynamic movements of the printing and application head, 20 It ensures that the loads generated are carried more evenly, instead of friction. It offers a rolling-based contact characteristic and structurally applies the moment effect. Developing a connection mechanism that will reduce the number of people who will solve the problem is also a solution of the invention. This is one of the technical problems it aims to solve. A BRIEF DESCRIPTION OF THE INVENTION In conventional technology, this refers to print and apply labeling. The head mounting mechanisms used in these machines are generally shaft-bushing based. It includes bearing structures and a carrier mechanism for the printing and application head. Due to its geometric arrangement, the mass distribution is offset with respect to the connection axis. 30 This occurs because a moment is generated on the connection axis during operation. and the moment in question occurs under repeated loadings, resulting in shaft-bushing contact. 3 This causes friction-induced wear on their surfaces over time. This wear creates gaps in the connection area, compromising mechanical stability. It has a negative impact. Based on this technical situation, the closest known technique to the invention (closest prior art) as such, the printing and application head is carried via a shaft-bushing bearing 5 the moment due to the connection to the mechanism and the angular positioning in that connection. Systems in which this formation occurs are accepted. The solution in question is derived from this known technique; (i) printing and application head (x) reduction of the connection distance between the carrier mechanism and (ii) bushing based Instead of a single bearing, a 10-inch bearing containing at least two bearings positioned on the same axis. They differ in terms of the use of a bedding arrangement. Considering these distinctive features, the objective technical problem is: Reducing the moment effect generated in the connection structure of the printing and application head, This prevents friction-induced wear due to the moment effect and the connection. by preventing mechanical voids that develop in the region over time 15 This is defined as increasing the positional stability of the system. The solution proposed within the scope of this invention reduces the connection distance. This reduces the distance of the head's center of gravity from the axis of connection, thereby reducing the moment. The arm is being reduced in size; in addition, a ball bearing system is being used instead of a bushing. Contact characteristics shift from sliding (friction) to rolling. 20 It is being converted. The use of at least two bearings positioned on the same axis. This improves the distribution of loads and provides a more balanced resistance to bending moments. A load-bearing structure is obtained. As a result of this structural arrangement, friction occurs in the fasteners and Wear is significantly reduced, limiting the formation of clearances on the shaft surface. It is structured in such a way that the mechanism maintains positional stability over long-term use. This ensures greater stability of the printing and application head during operation. This enables movement, creating a geometric interaction between the print head and the printing surface. This contributes to preserving the relationship. Furthermore, it reduces the moment effect. As a result, the loads to which other mechanical elements in the system are subjected are also more balanced. is becoming. 4 In this respect, the invention is not reduced to merely changing the type of bearing, The rearrangement of the connection geometry and the bearing structure must be considered together. It offers a holistic solution, whereby these features are applied together. The resulting technical effect is clearly different from known technology. LIST OF FIGURES Figure 1.

DETAILED EXPLANATION OF THE INVENTION The labeling machine described in this invention is used for products in industrial production and packaging lines. Printing and application devices used for printing and applying labels. It is a machine. As shown in Figure 1, the machine generally feeds labels. mechanism (1), operator screen (2), sensor mechanism (3) and motor-driven printing 5 and includes the application head mechanism (4). The label feeding mechanism (1) enables the transport of the label roll on the machine. and directs it to the printing area. The operator screen (2) shows the machine's operation. It is a control interface that allows the adjustment of the sensor parameters. mechanism (3) enables the perception of information regarding the location of the label and / or product 10 It provides. The motor-driven printing and application head mechanism (4) prints on the label. and the print head to be brought to the working position by moving it up and down. It is the main mechanism that is set in motion. Motor-driven printing and application head mechanism used in known technology. This is shown in Figures 2 to 5. In this structure, the carrier structure of the print and application head is 15 Its connection is established through a specific angular and distance positioning. The distance (x) shown in Figure 2 is relative to the connection axis of the print and application head. It indicates the offset position. As this distance increases, the weight of the head and the work the moment generated on the connection axis by the dynamic loads that occur during the process Its impact is also increasing. 20 Figure 3 shows the motor-driven printing and application head in the known technique. The image shows a rear view of the mechanism, and in this view, the head mass. The positional relationship with respect to the connection axis can be observed. The AA section given in Figure 4 and The detail view B given in Figure 5 shows the internal structure of the connection area in the known technique. This shows that in these structures, the connection is based on shaft and bushing bearing systems. This is achieved by a sliding contact between the shaft and the bushing during operation. Surface contact occurs. In this standard shaft-bushing connection structure, the printing and application head because the mechanism moves up and down in each working cycle The connection area is subjected to repeated loads. The 30-degree gap between the head and the supporting structure... The larger the distance (x), the greater the moment arm formed on the connection axis. This increases torque; the increased torque effect leads to higher friction at the shaft-bushing contact surfaces. 6 and causes wear and tear. This wear occurs over time in the connection area. This causes a gap to form. The gap that forms in the connection area affects the position of the print and application head. This negatively affects its stability. In this case, the print head attaches to the silicone print roller. The parallelism can be disrupted depending on the surface, and the force applied during printing may not be homogeneous. This cannot be transferred in this way, and the print quality deteriorates, especially with long-term use. Fluctuations can occur. Additionally, void formation can cause vibration in the system. This can cause head wobble and irregular operation of the spring elements. In the known technique, the printing and application head is attached to the carrier structure. The angular positioning that occurs during this process, the center of gravity of the printing and application head is 10 This causes it to be positioned offset from the axis of connection. This offset positioning, printing and application head movement on the connection axis It creates a bending moment, and the effect of this moment affects the connecting elements. This leads to the creation of additional loads. In the solution that is the subject of the invention, the word The issue is that angular positioning is not completely eliminated, but this positioning is 15 connection geometry to reduce the effect of the centroid offset it creates It has been reorganized. In this context, distance (x) and connection arrangement are considered together. by taking a way that reduces the distance of the center of gravity from the axis of connection. A settlement has been established. The invention concerns an improved motor-driven printing and application head mechanism 20 This is shown in Figures 6 to 8. The basic technical approach of the invention is based on the known art. rearrangement of the moment-generating connection geometry and connection The use of ball bearings instead of bushings in this region. In this context, pressure and The distance (x) between the application head and the carrier structure has been reduced and the connection system It is designed with a ball bearing structure suitable for backlash-free operation. 25 Figure 6 shows the motor-driven printing and application head mechanism that is the subject of the invention. A perspective view is shown. In this view, the print and application head are shown. positioned closer to the carrier block and the long moment arm in known technology It is observed that the resulting settlement has been shortened. In the known technique, as shown in Figure 2. Compared to the distance (x), the distance in question in the structure subject to the invention is significantly 30 It is observed that this is reduced in this way. This difference represents the moment generated on the connection axis. This is the fundamental structural difference that allows for the direct reduction of the arm. Distance (x) 7 By reducing the distance, the center of gravity of the head is lowered from the connection axis. Thus, the moment effect generated in the connection area during operation is structurally... is being reduced. In the connection arrangement described in the invention, the print and application head and the head carrier structure (4.3) The distance (x) between the center of gravity of the printing and application head is 5 It is determined in such a way as to reduce the distance from the axis. In this context, the distance (x) It is not merely a measurement indicating the assembly gap between two parts, but also includes printing and Determines the moment arm created by the application head relative to the connection axis. It is defined as a geometric distance. The distance in question (x) is defined in this way. By determining this, the connecting shaft 10 during the working cycles of the printing and application head. (4.2) and bending loads transferred onto bearing coupling elements (4.1) This allows for movement along a line closer to the axis. Ball bearing connection. In the components (4.1), preferably two bearings are used. Figure 7 shows the rear view of the mechanism that is the subject of the invention. This In appearance, the print and application head has a more compact connection with the carrier structure. 15 It appears to be organized within a relationship. This compact layout is not just about the machine. not only to reduce its volume, but also to prevent it from forming on the connection axis. It is a technical arrangement aimed at reducing the bending moment. Thus, the head movement during this process, the loads occurring on the fasteners are more evenly distributed. It is being moved. 20 Figure 8 shows the cross-sectional view (CC) of the mechanism described in the invention. This In the cross-section, a ball bearing is used instead of a bushing at the connection point of the printing and application head to the carrier structure. The use of a ball bearing coupling system is shown. The ball bearing coupling system is a connecting shaft. It is formed by at least two bearings positioned on it. The aforementioned The bearings are located on the same connection axis and the loads in the connection area are 25 not through a single contact surface, but through multiple bearing points It enables transportation. As shown in Figure 8, the ball bearing connection by axially spaced placement of the elements (4.1) on the connecting shaft (4.2) Double-point support is provided in the connection area. The bearings in question are the same. The alignment of the connecting shaft (4.2) on the axial direction ensures stability 30° It creates a system that will enable it to function in this way. 8 In the connection arrangement that is the subject of the invention, connection with bearing connection elements (4.1) The contact between the shafts (4.2) is a rolling contact instead of a sliding surface contact. It is arranged in such a way as to form. In this context, bearing fasteners (4.1), Load transfer via rolling elements in contact with the connecting shaft (4.2) It is structured in such a way as to accomplish this. Thus, in the known technique, the shaft and bushing 5 By eliminating the sliding contact that occurs between them, on the contact surfaces The resulting friction and associated wear effects are limited. Rolling This contact-based bearing arrangement uses axially spaced bearings. When evaluated together, the loads generated in the connection area are lower. It offers a structure that allows for friction-based and distributed transport. 10 In a ball bearing arrangement, the slip between the shaft and the bearing element Instead of direct contact, rolling contact occurs. Therefore, in the known technique... Surface friction occurring in the bushing structure is significantly reduced. Reducing friction decreases the formation of wear on the shaft surface and bearing area. limiting; the reduction in wear, however, leads to a gap of 15 in the connection area over time. It is structured in a way that will limit its formation. The invention utilizes at least two ball bearing structures, with a single point of contact. Instead of a bearing system, it creates an intermittent and axially balanced bearing arrangement. This structure, bending of the printing and application head during operation It counteracts the moments more evenly. Thus, the head mechanism operates in a more balanced manner. oscillation during operation, misalignment of the connecting shaft, or pressure This prevents the head from changing its position relative to the roller surface. The invention involves reducing the distance (x) and combining a bearing coupling arrangement. Their use represents two structural measures that complement each other in terms of technical impact. Reducing the distance (x) reduces the moment arm, while the bearing coupling arrangement remains 25 It enables loads to be transported with lower friction and without gaps. Therefore... The invention is a simple modification of the bearing system, using a bearing instead of a bushing. No. The invention is based on the simultaneous optimization of the connection geometry and the bearing characteristics. It is a holistic head connection mechanism. Thanks to this structure, the printing and application head mechanism can operate for a long period of 30 years. to limit the formation of gaps in the connection area during operating cycles It is structured. Preventing the connection gap allows the print head to press silicone. 9 It helps maintain its position relative to the roller. Between the print head and the print roller. Parallelism becomes more stable and the pressure force is transferred to the surface more evenly. It is possible. The mechanism described in the invention reduces the effect of moment, and at the same time, the spring... It also positively affects the working characteristics of its components. In known technology, connection 5 The void and oscillation that occur in this region cause the springs to exert an irregular compressive force. while this could cause transmission; the invention features a backlash-free bearing connection and a shortened Thanks to the connection distance, the springs' response to the load becomes more stable. Thus, the print and application head mechanism is more efficient throughout its operating cycles. It moves in a balanced and repeatable manner. 10 In a preferred application of the invention, the bearings are mounted on the connecting shaft. They are positioned at a specific axial distance from each other. This spaced arrangement allows the head It limits the bending or wobbling of the mechanism under the influence of moment. Alignment of the bearings on the same axis ensures smooth rotation of the connecting shaft and / or while allowing for oscillatory motion, it prevents the formation of mechanical voids in the system. It is structured in a way that will limit it. In another preferred application of the invention, the bearing coupling arrangement head It is mounted within the supporting structure. In this case, the connecting shaft passes through the bearings. It is attached to the carrier block and the loads from the print head are carried by the carrier structure. is met. Thus, load transfer is achieved directly and through a balanced mechanical path. 20 It happens. In another preferred application of the invention, a bearing coupling arrangement is used. It is configured to work without gaps or with reduced gaps. This This includes bearing mounting tolerances, connecting shaft diameter, and carrier structure. The bed frames inside are designed to be compatible with each other. Thus, 25 This prevents unwanted looseness in the head connection during operation. The working principle of the invention can be explained as follows: During the labeling process The sensor mechanism (3) generates a signal regarding the position of the product or label. This signal In line with this, the motor-driven printing and application head mechanism (4) is operated and The print head is moved towards the printing position. The movement of the print head is 30°. during this time, due to the shortened connection distance (x) between the head and the supporting structure The moment generated along the connection axis is reduced. At the same time, in the connection area... The ball bearing system carries loads resulting from motion with low friction. In the printing position, the print and application head operates with a silicone print roller. It comes into position. At this stage, the bearing linkage system connects to the head mechanism. This prevents gaps from forming at that point. Thus, the print head is 5 inches from the roller surface. its position is maintained and helps to distribute the pressure force evenly across the surface. The print head mechanism starts again after the printing process is complete. It is moved to this position. This cycle is repeated for successive products on the production line. One of the technical advantages offered by the invention is the reduction of wear in the connection area. The aim is to reduce friction-induced wear seen in bushing structures in known technology. In this invention, the reduction is achieved thanks to the ball bearing system. This also reduces the need for maintenance and It increases the lifespan of the mechanism. Another technical advantage of the invention is the structural reduction of the moment effect. Reducing the distance (x) between the head and the carrier reduces the moment arm. Reducing the torque arm reduces the effect of 15 on the connecting shaft and bearing elements. It reduces bending loads. This is especially true in industrial settings with high cycle counts. Mechanical stability is important in labeling applications. Another advantage of the invention is the prevention of gap formation in the connection area. It is structured in a way that will limit it. When no gaps are created, printing and application The positional stability of the print head is maintained. This stability is ensured by the print head being 20 degrees Celsius against the silicone print roller. It contributes to maintaining its parallel position. Another advantage of the invention is that it contributes to more efficient operation of spring elements. This ensures that the spring elements are protected because the gap and oscillation are reduced in the connection area. This allows for a more stable transfer of the printing force. This also applies between printing cycles. It reduces force variations. 25 This invention cannot be reduced to simply changing the bearing element, A mechanical system where the connection geometry and bearing characteristics are optimized together. It refers to the arrangement. The connection arrangement described in the invention is not just a bushing; it also includes a connection point. There is no change in the use of bearings, only in the connection geometry (distance x) and by optimizing the bearing arrangement together, the structural effect of the moment is reduced. It offers a holistic solution aimed at reducing [the risk of infection].
