    The present invention relates to a portable device for sticking leads that allows its durable and effective fixation when balancing the wheels in vehicles with aluminum wheels and lacquered. Thanks to a pneumatic drive, two pushers integral with the pistons of two cylinders come out of their equilibrium position and press the leads, previously placed in their position on the rim, against causing them to adhere strongly to it. Its hanging use, thanks to an air balancer, allows the operator to work more quickly and efficiently. This device allows adapting to any size of commercial tire by modifying only the geometry of the pushers and centering. It also has a tool, which allows the gluing of leads in a more extreme position of the profile of the rim. (Machine-translation by Google Translate, not legally binding)

    CONTRACT WEIGHTING DEVICE
    SECTOR OF THE TECHNIQUE
    The present invention belongs to the mechanical engineering sector and more specifically to the area of mechanical elements for the automotive industry.
    The main object of the present invention relates to a portable device for bonding leads that incorporates a system that allows them to be pressed, once placed in position on the tire, against it, when balancing the wheels of the vehicles. , in an effective and lasting way.
    15 BACKGROUND OF THE INVENTION
    When we talk about wheels, we are talking about a circular external rubber object mounted on a rim that can be made of aluminum or steel. Therefore, the tire and tire assembly are two pieces of different materials that rotate to cause movement of the vehicle on which they are mounted. Being two different pieces and being assembled, they must generate a balanced assembly to be able to turn correctly. It is totally impossible to manufacture both a tire and a perfect tire, which from any point of view its weight and texture is the same in any part of its design. When this assembly is assembled, it may tend to rotate more than one side than the other, that it weighs more than one side than the other, or that the tire and tire are not centered. To achieve this balance, tire balancers are used, these teams identify the set and examine whether they are well balanced for irregularities. Once identified, weights are placed on the inside of the tire to balance the centrifugal forces acting in already heavy areas
    30 when the tire makes the turn. It is what is known as internal correction that eliminates vertical rebound and lateral vibrations. The two weights that are used are: adhesive weights and tab or staple counterweights. Both perform the same function, but staple weights for steel wheels and adhesive weights are now more widely used.
    35 for aluminum and lacquered wheels. This is due to the fact that the natural shape of the steel wheel rim allows the weight to be secured through a clip designed for this purpose. However, in aluminum wheels, due to its softer mechanical nature than steel, it is not recommended that the weights be placed externally as they would fall more easily, in addition to creating an unsightly effect on the tire.
    5 Therefore, the adhesive weights that are placed inside the latter are hidden. These adhesive weights are placed directly by the operator without using any specific device, they are simply pressed manually against the tire. Subsequently, when circulating, the centrifugal force that forms on the wheels when turning
    10 press the weights against the tire causing them to finish fixing. The problem lies in the moment in which a tire in which they have been installed remains a stationary time since they end up releasing as the counterweights do not finish fixing and end up taking off. The objective of this invention is to provide the counterweights with sufficient pressure to
    15 that they are fixed effectively to the aluminum and lacquered wheels, so that, although they are not used for a certain time, there is no possibility of losing the fixation. It also seeks to improve the working conditions of the operator who will no longer have to manually exert force to fix the counterweight against the tire, but will have a device for it, avoiding overloads and musculoskeletal injuries.
    EXPLANATION OF THE INVENTION
    The device object of the invention, comprises a system for gluing leads on the tire when balancing wheels on a vehicle, whose purpose is to reduce
    25 the effort to be made by the operator during this task and allow it to be carried out in a faster and more efficient way. The device as a whole is constituted by two pneumatic cylinders to which different elements designed and manufactured to measure to achieve the device of the present invention have been joined in solidarity.
    30 The assembly is equipped with all the necessary elements to stop its operation except for the pneumatic supply unit; It must be connected to a pneumatic circuit because it lacks its own power supply. The device consists of the following constituent parts: two pneumatic cylinders or actuators, which allows the energy of the compressed air to be transformed into
    35 mechanical work, various fixed elements such as the push-button, the center, the crossbar, the valves and valve holders, the pneumatic control elements and the upper protection. It also consists of moving parts, those parts that have movement, such as the compression spring, the handle and the pushers that are responsible for transmitting the force to fix the leads on the tire when they are
    5 pushed by pneumatic cylinders. In its working position the device has an inverted T-shape, with the two cylinders arranged axially with their rods pointing outwards. Perpendicular to them by the midpoint that joins them, is the mast that supports the pneumatic control elements. Introduced into it at its opposite end it
    10 finds the handle, cylindrical and knurled to allow a better grip. As for the operation, it can be summarized as follows: it is a device that, by means of a pneumatic drive, allows the movement of two rim-shaped bodies that transmit the pressure provided by the
    15 pistons of two pneumatic cylinders to the leads, which have previously been placed in the ideal situation manually by the operator, and seal them to the tire effectively. Each time the button is pressed the device performs a complete cycle. This cycle consists of two movements: the first one of expansion until it presses firmly against the tire, so that it seals the lead against it maintaining a
    20 certain time in this position and the second recoil in which its original position is recovered. To expose and understand its operation, we will study step by step a complete cycle from beginning to end:
    1. Previously, the counterweight is placed in the place of the tire indicated by a wheel balancing machine which detects the appropriate weights in the tire and tire assembly. Once these irregularities have been found, the counterweights are placed by peeling off the cover of the adhesive strip and lightly pressing the counterweight against the tire until they are lightly adhered to it. Next, the device is inserted through the rear of the tire and placed in its correct position
    30 by fitting the centering on the center hub of the tire.
    2. Once it is verified that everything is in its correct position, the center is pressed against the tire, the handle will yield by pushing a compression spring that is housed in the support and the two rim-shaped bodies will come out of their position pushed by the pistons of the
    35 pneumatic cylinders
    3. A previously programmed timer will keep the counterweight against the tire pressed, that is to say the active cylinders with their pistons facing out, the time necessary for the counterweight to be firmly stuck against the tire. Once this time is consumed, the original position will be recovered.
    5 4. We can start a new work cycle.
    The device is intended for hanging use, with a view to making the work to be done by the operator as comfortable as possible. thanks to an intelligent assistance tool that allows to locate or move a load in the air in the direction of the z axis (vertical axis)
    10 quickly, accurately and easily as simply grab the handle and move the load, without the need for push buttons. Thus the device becomes an extension of the natural movements of the operator, increasing overall safety because reaction times are reduced and the effects of inertia with heavy loads are minimal.

    PREFERRED EMBODIMENT OF THE INVENTION
    In view of the aforementioned figures, and according to the numbering adopted, it
    15 an example of a preferred embodiment of the invention can be observed therein, which comprises the parts and elements indicated in detail below. Thus, as seen in Figures 1 to 11, a possible preferred embodiment of the lead bonding device, whose mission is to press the adhesive leads into position on the rim during wheel balancing, essentially comprises the
    20 following elements:
    • A pneumatic circuit according to the scheme in Figure 11, which is used to generate and transform force and movement by means of compressed air. This set is equipped with all the necessary elements for its operation, except for the power supply group, it lacks a source of
    25 own power so it must be connected to a pneumatic circuit. This
    formed by the following elements: Two pneumatic cylinders or linear actuators (1), SMC CXSJM25-40, which allows to transform the pressure energy into mechanical energy. These cylinders are compact, double acting, parallel stems, with
    30 guided by friction bushings. A pneumatic 5-way, 2-position, flip-flop directional valve, SMC SYA3220-C6 (2), the valves are elements that command or regulate start-up, stop and steering, as well as air pressure. A commercial valve with instant connection for diameter is used
    35 6 mm without thread.
    A timer (3) which, by combining three valves, a non-return throttle valve, a pressurized air accumulator and a 3-way, 2-position, monostable distribution valve allows to regulate the disconnection time. A commercial timer is used
    5 SMC EVR2110-F01, which allows manual time regulation by admitting a delay between 0.5 to 60 s. One directional valve 3 ways 2 positions (4), monostable, reference SY JA722-01 F. A mechanical micro valve (5) SMC VM1010-4NU-01 connection
    10 bottom with tilting lever, 3 ways, 2 positions, monostable. That allows the actuation of the pneumatic system. A non-return flow regulation valve in an adjustable, commercial direction with reference AS1001F-04, which regulates the amount of fluid that flows through them per unit of time, that is, the flow rate. These valves
    15 produce a narrowing in the conduction so that they cause a decrease in the flow through them, thus controlling the amount of compressed air that reaches the pneumatic actuator.
    • A chamfered cylindrical shaped center (6) made of Delrin plastic that
    allows you to center the device on the tire by inserting it into its hub. 20 is manufactured in plastic to avoid damaging it when introduced into it.
    • A sufridera (7) made of Teflon that serves as a connection to the centering device and the base, which supports the weight of the pneumatic cylinders. It is made of plastic to avoid rubbing the tire when resting on it.
    • A base (8) made of F-1 steel that supports the entire assembly and particularly the connection between the two pneumatic cylinders of the assembly.
    • Two bodies, which we will call pushers (9), (16) Y (fig. 9), whose profiles are adapted to the shape of the rim, made of aluminum and jointly attached to the pistons of the pneumatic cylinders so that upon receiving the air and move the plunger, and therefore the piston, these bodies are also
    30 displaced. Its body is made of aluminum (9) due to its lightness covering its ends of two pieces of Vulkollan (16) so that when they rest on the tire they do not damage it.
    • A plate (10) made of aluminum that serves as a connection between the mast of the
    device and pneumatic cylinders of the set. 35 • A mast (11) Y (fig. 7) made of Duralumin, which supports the assembly and which
    P201 730797

    It consists of a square profile part where the pneumatic system valves are supported thanks to supports manufactured for this purpose and a circular profile part that is inserted into the handle (hollow circular profile). At its end it has a drill where a male eyebolt is inserted that allows it to be connected to an intelligent assistance tool to work with the hanged device and thus facilitate its use.
    • A handle (12) and (fig. 8) made of duralumin and knurled to facilitate grip, which allows the operator to comfortably and safely grasp the device. It has a hollow circular profile, because inside it the circular part of the mast is introduced. The handle has a through hole machined and in turn the mast has a slide machined, both coinciding so that they can introduce through them a pin that can move along it. This circular part of the mast is not fully introduced, but rather a space is left where a compression spring is inserted in piano wire that is trapped between the end of the square profile area and the start of the handle, the which has a wall at that end. This washer and this spring play a fundamental role in the operation of the device since they are responsible for its commissioning, which is carried out as follows. When the handle is grasped and pushed down, it moves thanks to the mechanized slide on the mast, overcoming the force of the spring and compressing it so that the handle moves in that direction. The handle wall presses the rocker lever of the mechanical micro valve SMC VM1010-4NU-01 allowing air to enter the assembly and therefore activating the device. Once the force is stopped transmitting to the handle, the spring recovers its original position and after the established time, controlled by the timer, the device returns to its resting position.
    • A compression spring in piano wire C11000851000M (13) whose working length is 25,400 mm, external diameter 27.94 mm, wire diameter 2.16 mm, load index 5.6 N / mm and solid height 9.4 mm, which is located between the washer of the handle and the change of the profile of the mast from round profile to square profile, and allowing the whole upper part of the device to slide in that direction by pressing an actuator and starting it. Once the force stops exercising, it recovers its original position.
    • A male eye bolt (14) that is screwed to the end of the mast and serves as a grip for the intelligent assistance tool that allows working with the hanged device and thus facilitate its use.
    • A superior protection (15) in AISI-304 that prevents access to the components
    5 tires of the device, except for the manual timer regulator SMC which is accessible from the outside of the device to easily vary the recoil time of the pneumatic cylinders.
    • An intelligent assistance tool (fig. 10) that helps to use comfortably and
    Ergonomically shaped, the device object of the invention thanks to the feeling of weightlessness it produces.
