Description

The present invention relates to a feed device for feeding nails to a nail setting tool. Furthermore, the present invention relates to a nail setting device.

In addition, the present invention relates to an arrangement for sequentially driving a large number of nails into a component, and the use of such an arrangement.

Nails are among the oldest known fasteners in construction technology, such as house construction, shipbuilding, armaments technology, etc., mostly in connection with wood as a material. A distinction must be made between nails made of metal, mostly iron or steel, and wooden nails, which have been increasingly used in recent years to connect one or more wooden components. Traditionally, nails are driven into the material to be nailed with a hammer. As a rule, this requires several hammer blows, with the risk of bending the nail if the nail head is not hit in the extension of the nail shank.

With increasing industrialization, the production speed is becoming more and more important for economic reasons. For this reason, for example, nail setting devices have been developed that can be equipped with different drive concepts. have a special meaning Pneumatic nailers, which are usually operated with pressures of 5 to 6 bar. Driving speeds of around 25 meters per second can be achieved with such compressed air nailers.

Customary pneumatic nailers have a base body which includes a running tube for guiding a nail to be driven into a workpiece and a firing pin that drives it. The running tube extends between a front free end, which is placed on the workpiece to drive in a nail, and a rear, drive-side end, which is fluidically connected to the device for applying compressed air, and forms a firing channel on the inside.

Such compressed air nailers are widespread. In recent years, there has been an increasing need to manufacture components, for example wall elements of prefabricated houses, in an automated manner. To do this, it is necessary to automatically drive a large number of nails into a component one after the other. For this purpose, portal systems are usually used, in which a nail setting device is automatically moved in order to drive nails into a component at defined positions. The nails are usually fed one after the other to the nail-setting device in a magazine which is arranged on the side of the nail-setting device.

Such a structure has basically proven itself for the production of components. However, it is considered disadvantageous that the magazines of nails that are attached to the nail setting device carry only a very limited number of nails, so that the insertion of a new magazine is regularly necessary and is associated with a considerable downtime of the production plant.

The object of the present invention is therefore to provide a feeding device, a nail setting device and an arrangement for sequentially driving a large number of nails into a component, which avoid the aforementioned disadvantages and in particular enable nails to be fed and driven in as continuously as possible.

This object is achieved with a feed device of the type mentioned at the outset in that it has a hose line with a front connection for attachment to a nail setting tool and at least one rear connection for attachment to a supply unit for nails, nails being fed through the hose line one behind the other in their longitudinal direction Nail setting device can be supplied.

In a nail setting tool of the type mentioned at the outset, which includes a firing channel for guiding a nail to be driven into a component and a firing pin driving it, the object is achieved in that the nail setting tool has a connection for attaching a feed device according to the invention.

In addition, the object on which the invention is based is achieved in an arrangement for sequentially driving a large number of nails into a component with a nail setting device and a feed device connected to the nail setting device.

The invention is based on the idea of not storing the nails to be driven in directly on the nail setting tool in the form of a magazine, but transporting them over a longer distance to the nail setting tool if necessary. In other words, provision is made for nails to be made available in a supply unit remote from the nail setting device and in their longitudinal direction through a hose line to the nail setting device transport. A hose line has a certain flexibility and is suitable for reliably feeding the nails to the nail setting tool over a longer distance. Such a feed device is in principle suitable for automated production systems in which the nailing device is moved by a robot, as well as for hand-held systems in which a nailing device can be attached to a manually movable carriage.

By connecting the feed device to the nailing device, the arrangement according to the invention is created, with which the nails can be continuously fed over a longer distance directly to the nailing device and driven into a component. The feed device can be connected to the nail setting device in a manner known per se via a screw connection, in particular one with a union nut, or by another known coupling device.

In this case, the hose line can in particular comprise a hose which is made of polyamide, in particular PA12. These can be commercially available pneumatic hoses. Such hoses have proven to be particularly abrasion-resistant for the continuous feeding of nails in their longitudinal direction.

The feeding device preferably comprises a drive unit for feeding the nails in the direction of the front connection. In concrete terms, the drive unit can have an ejector pump, which is operated in particular by compressed air, which connects the hose line to a rear vacuum hose line, remote from the setting tool during operation, in which the nails can be conveyed by negative pressure in the direction of the front connection, and to a front overpressure hose line, close to the setting tool during operation , in which the nails can be conveyed in the direction of the front connection by overpressure, divided. In other words, two stages of promotion are provided. A negative pressure is provided in a rear section of the hose line, i.e. the nails are practically sucked forward by the connection for the supply unit, whereas in a front hose section near the nail setting device there is an overpressure, so that the nails are directed in the direction of the front connection or the nail setting tool be pressed with excess pressure. Such a structure can be realized by means of an ejector pump. This is a pump in which the pumping effect is generated by a fluid jet. A driving medium is blown into the ejector pump and conveyed forward, as a result of which a negative pressure is created in the area behind the ejector pump, through which the nails can be sucked in the present case. When passing through the ejector pump, the nails change from the underpressure to the overpressure area and are accelerated in the process.

The overpressure hose line is preferably shorter than the vacuum hose line. This configuration is based on the consideration that the nails are first conveyed over a relatively long distance by negative pressure before they reach the positive pressure region relatively close to the nail setting device.

In order to be able to implement continuous feeding into a nailing device, a buffer section or part of a buffering section can be provided in a section of the hose line adjacent to the front connection, in which the nails can accumulate before being fed into the nailing tool. In other words, before reaching the nail setting device, an area is provided in which nails come into contact one after the other, so that the nail tip of one nail hits the nail head of an adjacent nail. This creates a certain buffer so that it is ensured that a nail is always ready, the firing channel of a nail setting device to be fed. Such a buffer can minimize operational interruptions.

In the arrangement according to the invention, the accumulation zone can also extend into the nailing device, so that a rear part of the accumulation zone is arranged in the hose line of the feed device and a front part of the accumulation zone is arranged in the nailing device.

At the rear end of the accumulation section, an accumulation section sensor can be provided, which can detect whether jammed nails reach the rear end of the accumulation section. Such a sensor can be designed, for example, as a light barrier, touch sensor or in some other way. This makes it possible for a controller to recognize whether the buffer zone is filled with nails.

The feed device can also include a switchable diverter, which divides the hose line at its rear end area, so that two hose line sections open into the diverter at the rear, which have a connection at their respective rear end for attaching to a supply unit for nails. The setting switch preferably has a pneumatic cylinder in order to be able to switch over the setting switch. Such a switch has the task of being able to switch between at least two, in particular exactly two supply units for nails. If, for example, a delivery unit is empty and has to be fitted with new nails, production can continue in the meantime by switching to the other delivery unit. The control switch thus has the basic structure of a 3/2-way valve.

The feed device can also have at least one delivery unit for nails, which is connected to a rear end of the hose line is. The basic task of the delivery unit for nails is to provide nails in large quantities and to insert them reliably into the rear end of the hose line.

At least one supply unit can include a vibrating conveyor, in particular a vibrating spiral conveyor, by means of which nails can be fed hanging head to head to the end of the hose line remote from the nail setting device and can be inserted one after the other into the hose line. Such a supply unit is particularly suitable for nails with a head. These can be lined up and fed to the rear end of the hose.

In concrete terms, the vibrating conveyor can be connected to a bunker from which nails can be fed. Furthermore, sensor means can be provided in order to monitor the filling level of the bunker.

It is therefore intended that the nails can be introduced into a bunker in a disorderly manner and sorted by appropriate devices in such a way that they can be fed one after the other hanging upside down to the rear end of the hose line, where they are then sucked in by the negative pressure.

Furthermore, at least one supply unit can include a sorting unit which is designed to sort headless nails in particular in such a way that the nails point uniformly in a conveying direction and can thus be introduced into the rear end of the hose line. Nails without a head have to be handled differently and can be arranged, for example by vibrating chutes, in such a way that they point in the same direction and can thus be continuously inserted into the end of the hose line. Also in this embodiment, nails in one Bunker or other container are introduced, the level is monitored with sensor means.

According to a further embodiment, at least one supply unit can comprise an unwinding station for unwinding nail magazines and for pushing the nails out of magazines, so that the nails can be pushed directly from the nail magazine into the rear end of the hose line. This embodiment is suitable both for nails with and without a head. It is envisaged that the nails are wound up in magazines on wood in very large numbers. In the delivery unit, the nails are pushed out of the magazine by means of a pneumatic cylinder, for example, and fed directly to the rear end of the hose line.

According to a preferred embodiment, the feed device has two supply units, each of which is connected to a rear end of the hose line. This configuration is based on the consideration of enabling a continuous supply of nails. If a staging unit is empty, the switch can be used to switch to the other staging unit so that production can continue without interruption. In the meantime, a new nail magazine can then be inserted into the first supply unit.

The feeding device can also include a control unit. This can be configured in such a way that the introduction of nails into the hose line at the delivery unit/delivery units is interrupted when the accumulation zone sensor detects that the accumulation zone is completely filled with nails. In other words, the buffer zone forms a buffer that is only filled up when needed by new nails being fed forward by the supply unit. As long as the traffic jam with Nails is filled, such a replenishment of nails from the delivery unit is not required.

The nail setting device according to the invention preferably has a feed channel leading to the connection of the hose line, which runs obliquely to the firing channel and opens into it. The nails can be fed to the firing channel through this feed channel, which is connected to the hose line during operation. The feed channel can also include part of the accumulation section.

In concrete terms, separating means can be provided for this purpose in order to feed nails individually from the feed channel to the firing channel of the nail setting device. This configuration is based on the consideration that the nails, which lie point to head directly one behind the other in the accumulation section before reaching the nail setting device, must be separated in order to be able to drive them into a component.

In a specific embodiment, the separating means can comprise a holding device which is designed to block a front nail in the feed channel with a positive and/or non-positive fit. For this purpose, the holding device can comprise at least one locking element which can be moved transversely to the feed channel between a blocking position in which the nail is blocked before it reaches the firing channel and a release position in which the nail can be conveyed further into the firing channel. In other words, it is provided that the nails are released individually. For this purpose, a locking element is provided which, in its blocking position, protrudes into the feed channel and blocks the movement of the respective front nail, whereas in its release position it is preferably moved out of the feed channel so that the front nail is released.

The locking element can be designed in such a way that it can positively grip a nail with a head in front of the head. In the event that nails are to be driven in with a head, the locking element can thus grip the nail by the head and block it in a form-fitting manner. Specifically, this can be realized, for example, by a recess for the nail shank, which is formed on the locking element.

The retainer may also include a front locking member and a rear locking member. This configuration is based on the consideration of blocking both the foremost nail in the accumulation section and the following nail and thus all other nails in the accumulation section and thus preventing them from entering the firing channel. The leading nail can then be released, with the following nail still blocked. The front locking element can then be brought back into its blocking position before the rear locking element is brought into its release position. The nail that has been following up to now is thus moved forward in the direction of the firing channel due to the excess pressure in the accumulation section, but is prevented from entering the firing channel by the front locking element. The rear locking element is then brought back into its blocking position, so that the nails following in the accumulation section can be stopped again. Now the front nail can be introduced individually into the firing channel by bringing the front locking element into the release position. In other words, the nails are separated by alternating movements of the two locking elements. Such a procedure is particularly suitable for headless nails which, unlike nails with heads, cannot be gripped individually in a form-fitting manner.

The front locking element is preferably designed and arranged in such a way that, in its blocking position, it protrudes into the feed channel such that a front nail in the accumulation section can be stopped in particular with a positive fit before it is fed into the firing channel. It is thus provided that the front nail is prevented from entering the firing channel in that the feed channel is blocked mechanically by the front locking element. The tip of the nail preferably lies against the front locking element.

The rear locking element can be designed in such a way that it clamps a nail, in particular a headless nail, in the feed channel with a non-positive fit. In this way, the nail following the front nail can be frictionally clamped against the wall of the feed channel. The subsequent nails, which are pushed forward during operation by the prevailing overpressure, can be stopped in this way and individually introduced into the firing channel one after the other.

A pneumatic cylinder can be assigned to each locking element for actuation. This enables quick actuation and at the same time the application of relatively high forces.

The separating means can also include a flap mechanism which has a pivotable flap. This can be designed to selectively block the feed channel. In particular, such a flap can be mechanically coupled to the firing pin of the nail setting device, so that a nail can only be fed in when the firing pin is in a retracted position and the firing channel is free.

The arrangement according to the invention is particularly suitable for feeding and driving in lignocellulosic material, in particular nails Wood and/or a wood material, preferably an organically bound wood material. The nails particularly preferably consist of a synthetic resin-bonded laminated wood or a synthetic resin-bonded fiber composite material that contains lignocellulosic fibers from annual plants. The organically bound wood material can contain phenolic resin as synthetic resin. The organically bound wood material preferably contains synthetic resin in an amount of at least 5% by weight, in particular at least 10% by weight, preferably at least 15% by weight, particularly preferably at least 18% by weight and/or at most 40% by weight. %, in particular at most 30% by weight, preferably at most 25% by weight, particularly preferably at most 20% by weight.

Such nails made of a lignocellulosic material are particularly suitable for connecting components made of wood, since the material is of the same type and subsequent processing is possible without problems, in contrast to the use of metal nails and/or plastic nails. The nails can particularly preferably consist of a resin-bonded laminated wood or a synthetic-resin-bonded fiber composite material which contains lignocellulosic fibers from annual plants. Furthermore, the nails can have a density of >0.65 g/cm ³ , in particular a density > 0.85 g/cm ³ and preferably a density > 1.0 g/cm ³ .

The nails, which the arrangement according to the invention can be used to drive in, preferably have a nail shank, at the front end of which a nail point designed as a conical round point is provided, the point angle of the nail point being > 36°, in particular > 40°, preferably in the range of is 45 to 60° and is particularly preferably 45° or 60°. The diameter of the nail shank is preferably at least 2 mm, in particular at least 3 mm, preferably at least 4 mm and/or at most 8 mm, in particular at most 6 mm, preferably at most 5 mm.

The arrangement according to the invention can be used in such a way that the nails are driven directly into a component, i.e. without creating a pilot hole, particularly when it is used for feeding and driving in nails made of lignocellulosic material. This enables a particularly rapid and therefore economical driving in of a large number of nails one after the other.

The figure 1 Figure 1 shows an arrangement 1 for sequentially driving a plurality of nails into a component according to the present invention. This comprises a nail setting device 2, which is designed here as a compressed air nailer, and a feed device 3 connected to it, which is designed to feed nails to the nail setting device 2 one after the other for driving them into a component.

The nail setting device 2 is in the Figures 2 to 4 shown in detail. The present case is a nail setting device 2 for attachment to an automated production system. The nail setting device 2 has a base body 4 in which a firing channel 5 for guiding a nail to be driven into a component and a firing pin 6 driving it is formed. The firing pin 6 is actuated pneumatically and is connected to a pneumatic piston 7 for this purpose.

A feed channel 9 is formed in a front device nose 8 of the nail setting device 2, which runs obliquely to the firing channel 5 and opens into it. The feed channel 9 serves to feed nails to the firing channel 5 one after the other, so that they can be driven individually into a component. In the present case, the feed channel 9 is designed in several parts and extends over the device nose 8 and a tube 10 attached to it, at the free, rear end 11 of which a connection 12 for attachment to the feed device 3 is provided.

In the present case, the feed device 3 comprises a hose line 13 with a front connection for attachment to the nail setting tool 2. At the rear, the hose line 13 branches into two hose line sections 13a, 13b, which each run to a supply unit 14, as shown in FIG figure 7 is shown in detail. The supply units 14 are each arranged on a movable support frame 15 made of metal profiles and each comprise an unwinding station 16 for unwinding nail magazines 17 and means for pushing the nails out of the magazines. In concrete terms, the nails are pushed out of the nail magazines by means of pneumatic cylinders 18 and are thus introduced into the rear ends of the hose line 13 that are remote from the setting tool.

A hose line section 13a, 13b runs from each delivery unit 14 to a switchable control switch 19, which is shown in detail in FIG figure 6 is shown. The control switch 19 has two rear connections 20, to each of which a hose line section 13a, 13b running to an actuating unit 14 is connected. Furthermore, a front connection 21 is provided, which is provided with the hose line 13 leading to the nail setting device 2 . The control switch is therefore designed in the form of a 3/2-way valve and can be switched over by means of a pneumatic cylinder 22 so that one of the two delivery units 14 running hose lines can be connected to the hose line 13 which leads to the nail setting device 2.

The feed device 3 also includes a drive unit 23 in order to be able to convey nails from the respective supply unit 14 in the direction of the nail setting device 2 . The drive unit has a compressed air-operated ejector pump 24, which divides the hose line 13 into a rear vacuum hose line 25 remote from the setting tool and a front overpressure hose line 26 near the setting tool that is significantly shorter than this. The Drive unit 23 is detailed in figure 5 shown. This has a negative pressure connection 27 for the negative pressure hose line 25 on the left side and a positive pressure connection 28 for the positive pressure hose line 26 on the right side. A compressed air connection 26 is also provided in the middle for connecting compressed air.

In the overpressure hose line 26 and in the feed channel 9 of the nailing device 2 there is an accumulation section 30 in which the nails can accumulate before they are fed into the firing channel 6 of the nailing device 2, as is the case, for example, in figure 4 is shown. A buffer zone sensor 31 is provided at the rear end of the buffer zone, remote from the setting tool, by means of which it can be detected whether the buffer zone 30 is completely filled with nails.

Separating means 32 are also provided on the nail setting device 2 in order to feed nails individually from the feed channel 9 to the firing channel 5 of the nail setting device 2 . In the present case, these separating means 32 include a holding device 33 which is designed to block a front nail in the feed channel 9 in a positive and/or non-positive manner.

Specifically, the holding device 33 comprises a locking element 34, which can be moved transversely to the feed channel 9 between a blocking position, in which the nail is blocked before it reaches the firing channel 5, and a release position, in which the nail can be conveyed further into the firing channel 5. In the present case, the locking element 34 is actuated by means of a pneumatic cylinder 35 .

During operation, it is provided that nails are fed continuously to the nail setting device 2 . These 14 nails are pushed out of the respective nail magazine 16 and in the rear end of the supply unit Hose line 13 introduced. In the area of the hose line between the supply units 14 and the drive unit 23, the nails are conveyed one after the other in their longitudinal direction by negative pressure. After passing through the drive unit 23, the nails are conveyed by overpressure in the overpressure hose line 23 to the nail setting device 2. Before they reach the firing channel 5, the nails are stopped by the holding device 33 so that there are several nails in the accumulation section 30. If a nail is now to be driven into a component, a nail is fed to the firing channel 5 by means of the separating means 32 and driven into a component by the firing pin 6 .

The sensor 31 is used to continuously monitor whether the buffer zone 30 is completely filled with nails. In this case, the supply units 14 are controlled in such a way that no further nails are introduced into the hose line 13 . Only when the buffer section 30 is no longer completely filled with nails are nails supplied from the supply units 14.

If the nail magazine 17 of an unwinding station 16 is empty, the switching device 19 can be used to switch to the other supply unit 14 so that nails can continue to be fed continuously to the nail setting device 2 . In the meantime, a new nail magazine 17 can be inserted into the unwinding station 16. In this way, continuous operation of the nail setting device 2 is possible.
