Definitions

  • the invention relates to a pneumatic nailer with a safety device which can set the pneumatic nailer from a ready-to-trigger state to a locked state and which is controlled by a pressure in a safety control chamber.
  • the contact initiation process poses an increased risk of injury.
  • the user holds the manual trigger not only pressed when he wants to place the pneumatic nailer on the same workpiece at a distance of a few centimeters from the last fastener driven in, but also when he changes to another, remotely located workpiece, can inadvertently touch an object or Body part can be triggered with the touch sensor.
  • accidents can occur if a user (ignoring important safety regulations) climbs onto a ladder with the pneumatic nailer, keeps the trigger pressed and accidentally brushes his leg with the touch probe.
  • Some known pneumatic nailers seek to reduce this risk associated with the contact release operation with the aid of a safety device which only permits contact release for a short period of time after the trigger is actuated or after a driving-in operation. Once the period has passed, the trigger must be released first.
  • the pneumatic nailer described therein has a trigger and a touch-down sensor, each of which is assigned a control valve.
  • the known device has a safety device with a control chamber, the pressure of which acts on a locking piston. In a certain position of the locking piston, the triggering of a driving-in process is prevented.
  • the control chamber is ventilated via the control valve assigned to the trigger and a throttle. As a result, after the trigger has been actuated, contact triggering is only possible until the pressure in the control chamber has exceeded a predetermined pressure threshold. The pneumatic nailer is then blocked until the trigger is released and the pressure in the control chamber has dropped below the pressure threshold again.
  • the pressure prevailing in the control chamber acts on a valve sleeve that surrounds the control valve and finally shifts this valve sleeve into a blocking position in which a complete actuation of the valve pin can no longer vent the main control line, so that a contact triggering is not possible.
  • a pneumatic nailer with a safety device has also become known, which in one exemplary embodiment has a small piston which changes the position of a rocker integrated in a triggering device.
  • the piston is pressurized in a control chamber and moved against the force of a spring.
  • the safety device has a sleeve which is arranged around a valve pin and can be displaced against the force of a spring. The position of the sleeve is also controlled by the pressure in a control chamber. In both cases, triggering of a driving-in process is prevented when the piston or the sleeve is in a certain position.
  • the control chamber is ventilated from the working volume with each driving process and then slowly vented through a small vent opening.
  • a common feature of the discussed prior art examples is that the pressure over time in the control chamber is significantly influenced by a gradual venting or aeration through a throttle or another small opening.
  • the timing of the safety device achieved in this way depends on the cross section of the opening used in each case. In connection with small control chambers in particular, relatively small opening cross sections must be used, which makes the known solutions structurally complex and sensitive to contamination.
  • a pneumatic nailer has become known, which can be used in a contact release operation.
  • a triggering device of the known pneumatic nailer comprises a touch-down sensor and a trigger in which a rocker is pivotably articulated.
  • the surface sensor takes a free end of the rocker with it on its way up, so that when the trigger is actuated, a control valve is actuated by the rocker, which triggers a driving-in process.
  • a downward movement of the rocker is slowed down by a damper so that further contact trips are possible within a predetermined period of time.
  • the pneumatic rodent is used to drive in fasteners such as nails, pins or clamps.
  • the pneumatic nailer can have a magazine for the fastening means, from each of which a fastening means is fed to a receptacle of a mouth tool of the pneumatic nailer.
  • a driving action is triggered, compressed air is applied to a working piston of the pneumatic nailer.
  • the working piston drives a driving plunger which is connected to the working piston.
  • the driving plunger hits a rear end of the fastener in the receptacle of the mouth tool and drives the fastener into the workpiece.
  • the triggering device can in particular have a manually operated trigger, for example in the form of a trigger lever or slide.
  • the triggering device can have a control valve or a plurality of control valves, which is or are actuated by the trigger and possibly by further elements of the triggering device, for example a touch-down sensor and / or a power transmission device coupled to it and / or to the trigger.
  • a driving-in process is triggered, provided the pneumatic nailer is in its ready-to-trigger state. If, on the other hand, the pneumatic nailer is in its locked state, it is not possible to trigger a driving-in process by actuating the triggering device.
  • the pneumatic nailer has a safety device which is designed to put the pneumatic nailer from the ready-to-trigger state to the secured state.
  • An example of this change of state is the resetting of the pneumatic nailer from a contact release mode to a single release mode.
  • Another example could be a shutdown of the pneumatic nailer, which requires a renewed start-up of the pneumatic nailer for a further driving operation, for example by pressing a reset button. To switch off the pneumatic nailer, it could be completely vented, for example.
  • the safety device can be designed in such a way that it sets the pneumatic nailer from the ready-to-trigger state to the secured state when the pressure in the control chamber passes a predetermined pressure threshold, that is to say either exceeds or falls below this pressure threshold.
  • a predetermined pressure threshold that is to say either exceeds or falls below this pressure threshold.
  • the pressure in the control chamber is not, or at least, is not significantly dependent on a gradual inflow or outflow of air through a throttle or the like.
  • the pressure in the control chamber is controlled by means of a control valve, the control valve member of which is movable along an adjustment path and is coupled to a damper.
  • the damper influences the time course of the movement of the control valve member.
  • the control chamber can be vented or vented, for example, when the control valve member reaches a predetermined position (hereinafter also referred to as the first switching point) along its adjustment path.
  • the damper can be matched to the control valve and the processes taking place in certain work steps in such a way that this predetermined position is reached after a predetermined period of time.
  • the predetermined period of time can begin with a specific event, for example with an actuation of a trigger and / or a touchdown sensor and / or a driving-in process.
  • the damper is a mechanical component that dampens movement in a specific direction by opposing the movement with a counterforce acting in the opposite direction. This counterforce can in particular be dependent on the speed of the movement, in particular essentially proportional.
  • the movement that is damped by the damper can be generated by a force that is exerted, for example, by a spring or pneumatically.
  • Suitable dampers are available in a wide variety of designs. They can be integrated into the pneumatic nailer in a variety of ways.
  • control valve member is influenced in the desired manner, ie in such a way that the pressure in the control chamber is controlled in such a way that the safety device reliably relocates the pneumatic nailer from the ready-to-trigger position to the secured state in a potentially dangerous situation.
  • a particular advantage of the invention over the known pneumatic nailers with a control chamber is that the pressure in the control chamber can be controlled without a throttle or another, comparatively small opening cross-section.
  • the pneumatic nailer is less susceptible to contamination, which is often difficult to avoid in harsh practical situations.
  • the pressure in the control chamber can be brought much quicker to the value required for the correct functioning of the safety device using the control valve provided for this purpose, which can also improve the reliability of the safety device.
  • the damper is coupled to the control valve member in such a way that it slows down a movement of the control valve member at least along a section of the adjustment path.
  • the desired time control is achieved by slowing down the movement.
  • the triggering device has a touch-down sensor which is designed to shift the control valve member into a fully actuated position when the pneumatic nailer is attached to a workpiece.
  • the touch-down sensor can be a mechanical component which projects beyond the front end of a muzzle tool and is held in this position, for example, by a spring, until the pneumatic nailer is attached to a workpiece. Then the surface-mounted sensor is shifted against the driving direction until a muzzle tool of the pneumatic nailer bears against the workpiece or almost bears against it.
  • the touch sensor acts directly or indirectly on the control valve member in such a way that the control valve member is in this fully actuated position of the touch sensor is also in a fully actuated position.
  • the pneumatic nailer can in particular be constructed in such a way that this action of the touchdown sensor on the control valve member occurs regardless of the position of a trigger.
  • the touch-down sensor can perform further functions, for example triggering successive drive-in operations in a contact triggering operation. These additional functions can generally be performed using a separate control valve that interacts with the touch-down sensor. As will become clear from the exemplary embodiment explained in detail later, however, the different functions can be performed in particular with the aid of a control valve arrangement, in which the control valve that controls the pressure in the control chamber is integrated.
  • the embodiment of the invention with a touch-down sensor is characterized in that the control valve with which the pressure in the control chamber is controlled is simply and reliably set to a defined position when the touch-up sensor is actuated.
  • the control valve member can remain in this defined position until the pneumatic nailer is removed from the workpiece.
  • control valve member has a first switching point at which the control valve aerates or ventilates the control chamber, and the damper is coupled to the control valve member such that after the pneumatic nailer is removed from a workpiece, the control valve member starts the first switching point from the full actuated position reached after a predetermined period of time.
  • the safety device moves the pneumatic nailer from the ready-to-trigger state to the locked state after the specified period of time has elapsed. The pneumatic nailer remains in the ready-to-trigger state within the specified period of time, so that if the pneumatic nailer is set up for this purpose, in particular contact tripping is possible.
  • the pneumatic nailer has a main control line which has to be ventilated or triggered to trigger a driving-in process
  • the control valve member has a second switching point at which the control valve ventilates or aerates the main control line.
  • a driving process can be initiated in different ways by means of the main control line.
  • an embodiment with a main valve and a pilot valve, which is controlled via the main control line is known.
  • other constructions with or without a pilot valve are also conceivable.
  • it is only important that the driving-in process is triggered by venting or venting the main control line.
  • This type of construction usually requires that the main control line is vented (if the main control line is to be ventilated to trigger a drive-in process) or that the main control line is ventilated (if the main control line is to be triggered) before another drive-in process can be triggered Is venting).
  • This requirement is met as soon as the control valve member reaches its second switching point.
  • the second switching point can be reached very quickly starting from the fully actuated position of the control valve member, for example when the pneumatic nailer has been removed from a workpiece by, for example, 1 mm and the touchdown sensor is still correspondingly close to its fully actuated position.
  • the second switching point can be reached clearly before the first switching point, starting from the fully actuated position of the control valve member.
  • a high frequency of driving operations can be achieved, particularly in a contact triggering operation.
  • a damping effect of the damper is limited to one of two possible directions of movement of the damper.
  • the damper can be designed such that it does not take effect when the control valve member is moved to a fully actuated position. It then specifically dampens only the backward movement of the control valve member, which is important for the desired timing behavior. A simple displacement of the control valve member is possible in the other direction of movement, which enables a smooth movement sequence and avoids unnecessary wear.
  • the damper has two elements which are movable relative to one another, the relative movement of which it dampens, one of the two elements being fastened and / or articulated to a part of the pneumatic nailer fixed to the housing and the other of the two elements being attached to the attachment sensor, to the control valve member or to a force transmission device, which is designed to transmit a force from the touch-down sensor to the control valve member, is attached and / or articulated.
  • the three variants of this configuration relate to different constructive solutions for the integration of the damper in the pneumatic nailer.
  • the damper dampens the relative movement between Attachment sensor and housing of the pneumatic nailer.
  • the relative movement of the touch sensor relative to the housing is essentially straight and over a defined, relatively long distance.
  • the damper is a linear damper or a rotary damper. Both designs are suitable for the invention and are available in different versions.
  • the damper is a fluid damper or a friction damper.
  • the damping is achieved by the flow resistance of a gas or a liquid, in the case of a friction damper by the friction between two solid bodies. Both mechanisms are suitable for the invention and are available in different versions.
  • the safety actuator is shifted from the trigger position into the safety position when the pressure in the control chamber passes a predetermined pressure threshold. If the pressure in the control chamber corresponds to the predetermined pressure threshold, the force exerted by the pressure in the control chamber and the counterforce exerted on the safety actuator in another way can be in equilibrium.
  • a spring 20 is arranged between the housing 10 and the touch-down sensor 14 and presses the touch-down sensor 14 downwards.
  • a damper 22 is arranged between the housing 10 and touch sensor 14, which in the example shown is a Has cylindrical damper housing 24 in which a damper plunger 26 is slidably guided. The damper plunger 26 protrudes from the lower end of the damper housing 24 and is attached to the touch-down sensor 14 at its free end.
  • the damper 22 has a fastening section 28 which is fixedly connected to the damper housing 24.
  • the upper, free end of this fastening section 28 is articulated with a horizontally arranged pin 30 to an elongated hole 32 formed in the housing 10.
  • the length of the elongated hole 32 is less than the length of the elongated hole 16, in the example approximately half as large.
  • the damper 22 is designed in such a way that it dampens a movement of the damper tappet 26 downward, ie out of the damper housing 24, but not in the opposite direction, ie into the damper housing 24. This leads to the fact that the attachment sensor 14 can be displaced upward by the damper 22 essentially unaffected when the pneumatic nailer is attached to a workpiece. After removal of the pneumatic nailer from a workpiece, the interaction of the spring 20 with the damper 22 determines the speed at which the touch-down sensor 14 moves down again when the pin 30 is in contact with the lower end of the elongated hole 32 and for the further downward movement of the damper plungers 26 must be pulled out of the damper housing 24.

  • the fourth O-ring 94 has moved out of the seal, so that the line 72 is now connected to the main control line 58 via the transverse bore 108. Since the line 72 is still connected to outside air via the trigger valve 42, this does not yet trigger a driving-in process.
