Description

1 TARIFF CAP CLOSING MACHINE FOR AEROSOL CANS AN IMPROVEMENT Technological Field: The invention involves precise alignment, controlled snapping, and different types of caps onto aerosol cans. Lid closure / fastening to ensure compatibility with box sizes. It is related to an improvement made to the machine. 10 State of the Art: In aerosol can capping procedures, the caps should be positioned correctly over the can opening. It needs to be brought into alignment and driven in with a specific pressing force. This process is done from the outside 15 Although it seems simple, as the production line speeds up, the small gap between the lid and the box opening... Even alignment errors can cause crushing on the lid, deformation at the box opening, axial misalignment, or other issues. This can lead to problems such as the lid not fitting properly. Therefore, the lid In sealing machines, it is not enough to simply generate the sealing force, At the same time, the lid transfer, box positioning, and snapping motion are all interconnected. It needs to work together in a delicate and coordinated manner. Switching to aerosol cans of different sizes and dimensions in existing systems is a common problem. Operator intervention is required at times. Box height, lid diameter, or box When the opening position changes, the cover transfer line, the fastening group or the mold 25 The distance needs to be readjusted. When these adjustments cannot be made precisely enough... The lid may not fit perfectly centered on the box opening. This can result in a defective product. This increases the rate and also causes stoppages in the production line. Another problem encountered in lid fastening mechanisms is high cycle 30 It is the fatigue of the moving parts in the numbers. Especially in the upward direction of the fastening group. In structures where continuous pressure is maintained by a spring, the spring fatigues quickly. 2 It is possible for it to lose its flexibility or break. Numerous impact operations per minute. This situation becomes more pronounced in the machines being manufactured, and machine maintenance... It increases the need. In conventional machines, small production defects found on the lids during the lid stamping process. 5 Errors can also create problems. Dimensional deviations in the lid shape, burrs, or Deformities, jamming and straining during the movement of the trigger arm. This can create stresses that not only lead to faulty cover installation, also places additional load on the trigger arm, shaft, camshaft and connecting parts. This can reduce the lifespan of the machine. 10 During the upward retraction of the fastening element after the cover fastening process Technical problems may also arise. The cap or aerosol can, with its ejector nozzle... The friction, compression, or temporary adhesion effect that occurs between them causes the fastening element to snap. It may tend to move upwards along with the load. This situation causes the box to carry 15 This can disrupt its position in the line, cause jamming in the next cycle, or the product It can even prevent it from progressing properly. In conclusion, the basic need for existing aerosol capping machines is different cans. capable of quickly adapting to dimensions, precisely protecting the mounting axis, high 20 In terms of cycle count, it puts less strain on mechanical elements and the post-processing box line a more stable mechanical structure that ensures it remains securely in place It is the development of. Description of the invention: 25 The main purpose of the invention is to enable the high-speed, repeatable application of caps onto aerosol cans. and a more stable cap closing machine that ensures flawless operation. The goal is to improve existing lid snapping systems to accommodate different box sizes. Precise alignment of the bolt opening and the box opening, spring fatigue at high cycle numbers, 30 Problems such as lid jamming and the box being lifted upwards after sealing. This can be seen. The invention addresses these problems with mechanical adjustment and sensor-assisted design. 3 positioning, cam path arrangement, pneumatic support and restraint structure all in one. This ensures a more reliable study. Thanks to the side ear and slot structure included in the invention, the cover transfer line or chassis can be connected. The associated movable part has limited angular movement according to the size of the aerosol can. 5 It is able to do so. Thus, each product change requires extensive mechanical disassembly or lengthy disassembly. The capping line is compatible with the aerosol can dimensions without the need for adjustment procedures. It is possible to make it so. The cam path, located beneath the cam body, allows for more regular and 10-degree movement of the trigger arms. It enables controlled motion tracking. The cam path is located on the underside. especially revised according to the cam body molding system or different product dimensions It provides ease of assembly in situations where it is required. This structure facilitates maintenance and parts. Reducing changeover times helps the machine return to production faster. It offers. 15 One of the key advantages of the invention is that the aerosol can is sealed after the stamping process. The aim is to prevent it from being carried upwards. The lid or box, while the snap lever is being pulled back, tends to move upwards along with the piston due to compression or friction. This is possible. The limiting cam block prevents this situation by ensuring the box operates within 20 seconds. This ensures that it remains intact. Thus, it prevents defective products, lid deformation, and machine malfunctions. The risk of entrapment is reduced. The splined shaft structure associated with the trigger lever ensures a longer lifespan and more efficient mechanism. It helps to work comfortably. There are minor manufacturing defects on the covers. When there are dimensional errors or morphological distortions, jamming and Jamming can occur. Splined shafts reduce such stresses, protecting both the product and the machine. It prevents its employees from getting hurt. The use of pneumatic pistons, as described in the invention, is particularly suitable for high-capacity production. This provides a significant advantage. The striking group is under continuous upward pressure. In structures where this load must remain in place, when this load is borne solely by the spring, the spring shortens. 4 It can become fatigued or lose its springiness over time. A pneumatic piston is fixed and By providing support to the fastening group with adjustable air pressure, it relieves the load on the spring. This reduces the strain on the machine, allowing it to operate stably for longer. is able to work. The relationship between the sensor and the molding system also enhances the ease of use of the invention. The sensor detects the size of the aerosol can and the molding system adjusts accordingly. Adjusting the distance reduces operator errors. For boxes of different sizes. By correctly adjusting the cap snapping distance, excessive pressure, insufficient snapping, or Problems such as axial misalignment are prevented. 10 In conclusion, the invention not only speeds up the aerosol capping process, but also... It doesn't just stay that way; it's also more controlled, requires less maintenance, and offers different products. It offers a machine structure that adapts more easily to the dimensions. The correct lids fastening on the axis, securely holding the boxes during the process and fastening 15 Production quality and machine are improved thanks to the group experiencing less mechanical stress. Service life is increased. Explaining the Figures: The invention will be described by referring to the attached figures, so that the features of the invention can be explained.

The following description provides 5 points to ensure a complete understanding of the present invention. Many specific details have been provided. However, the present invention can exist even without these details. Its applicability will be clearly understood by experts in the field. The invention relates to the transfer of caps onto aerosol cans and the application of those caps to aerosols. A 10 developed for controlled closing / stamping of the mouth of boxes. It is related to the cap closing machine (1). The cap closing machine (1) is generally a chassis (10) which forms the carrier structure of the machine, to the cover fastening station a cover transfer belt (11) that enables the transfer of the cover, the cap snapping action a guiding cam body (15), in relation to the said cam body (15) At least one movable trigger lever (18), adjustable according to the size of the aerosol can 15 It includes a sensor (29) and a mold system (30) that enables it to be made. Cap transfer tape (11) is used to attach caps to aerosol cans. This ensures that the aerosol is transported to the area in a regular and controlled manner. In this way, the caps prevent the aerosol from being damaged. It is brought to a position where it can be aligned with the mouth of the box. Lid transfer tape (11), 20 on the chassis (10) of the machine or on a carrier part associated with the chassis (10) They are positioned so that the covers move in the correct line before the nailing process. and the force to be applied by the trigger lever (18) must be carried out in the correct area. It is provided. The chassis (10) forms the main load-bearing structure of the machine and the cover conveyor belt (11), cam elements such as the body (15), the fastening arms (18), the sensor (29) and the molding system (30) It allows them to be positioned in a compatible manner. On the chassis (10) or A side ear (12) connected to the chassis (10) and a slot on this side ear (12) (13) is located. Slot (13) is located in the machine according to the size of the aerosol cans. It allows for limited angular movement of the carrier portion. In this context, cover transfer band (11) or shaft associated with the band, slot (13) 8 It can slide and move, and the relevant part of the chassis adapts to the size of the aerosol can. It can be positioned slightly at an angle (Figure 1 and Figure 3). Thanks to this structure... More precise cap transfer and snapping line for different sized aerosol cans. It is ensured that it is adjusted accordingly. The lid closing machine (1) is a main drive mechanism associated with the main center shaft (14). It includes. The main drive mechanism is not separately referenced in the drawings. Together, they give rotational motion to the main center shaft (14). The main center shaft (14) with its rotation the cam body (15) and the trigger arms (18) associated with the cam body (15) It moves in the circumferential direction. Thus, the machine continuously and sequentially attaches the cover. 10 The cycle is obtained. The cam body (15) is one of the basic elements that direct the movement of the striking arms (18). It is one of them. A cam on the cam body (15) or in relation to the cam body (15). The road (16) is located. The cam road (16) is located just below the cam body (15). Therefore, the cam body (15) can be easily changed according to the mold system. It is possible to make it possible. The trigger lever (18) is connected to the main cam wheel (23). The subject moves along the cam path (16). The cam path of the main cam wheel (23) With its progress on (16), the rotational movement of the main center shaft (14) is for the fastening arm (18). It is converted into a controlled snapping motion. In this way, the snapping lever (18) cap snapping 20 At the station, approach the mouth of the aerosol can, place the cap on the can. It presses / slaps and then pulls back. The snap lever (18) is a mechanical device that enables the caps to be pressed onto the aerosol can. It is an element.
