Description

DETAILED DESCRIPTION OF THE INVENTION The v4Fi according to the invention is equipped with three substantially parallel and mutually movable guide rails on the sides, and is capable of driving separate nails into the nails, etc. 111 of the device. *This concerns horizontal magazines.

Nailing has been used in many ways due to its advantages such as high driving efficiency, low operator fatigue, and above all great time savings. The equipment is used in carpentry, house construction, cargo construction, and board manufacturing, especially in compressed air operated installations. This device can drive up to four nails per second. For this purpose, the device Kl! is required to drive nails efficiently. Must be filled! There is. Essentially s different systems are known for this purpose.

According to the No. 10 system, the nails are connected to the strip-like structure in a vertical positional relationship by means of auxiliary means.

° In this case, the nails have their heads shaped accordingly and are bonded to one another over the entire length of their bodies, for example using adhesive. With the common head shape projecting radially from the barrel on all sides, lines or bands are required to hold the nails apart from each other.

The above-mentioned known systems are expensive and make the nails more expensive to manufacture. Driving auxiliary means, such as wires, bands, etc., which are no longer needed after separating the nails, can also cause failure of the device. Stamping the strip structure requires a complex and failure-prone mechanism to feed it into the device.

According to a second known system, the nails are fed into the driving device in pieces. In a driving device working with this known system, the nails are provided with a magazine consisting of three guide rails extending substantially parallel to each other and movable laterally with respect to each other. This magazine is inclined in the normal position of use of the cough device, so that a nail with a slight lateral play relative to the guide rail slides under gravity into the nail slot.

Loose O-nails are loaded into the magazine using a so-called vibrating device.

The known nail loading system, which is simple in principle, has certain drawbacks. If you work on a construction site, for example on a sloping roof, the device will work! It is not always possible to keep it in a vertical position. Nail replenishment may be interrupted if the person moves out of this vertical position and the wfj gin no longer requires a slope.

Due to various frictional effects, the nail does not always slide off quickly enough even when the driving device is in the correct position.

It is therefore an object of the present invention to provide a simple and safely functioning magazine for loading loose nails into a nail-driving device.

According to the invention, this object is achieved in that the guide rails have round tooth-shaped cutouts facing each other, and transverse ones to facilitate relative movement in the longitudinal direction.

It is actually accepted within the cutout of the individual pieces of Im-type. Due to the relative movement of the two guide rails, the nails held in all magazines are advanced by one section, regardless of the position of the magazines. Stagnation of individual nails does not occur.

After one transfer stroke, the guide rail must return to its starting position again. In order to prevent the nail from returning, it is expedient to design the recess in a serrated manner with a shorter tooth flank in the loading direction. During the transfer process,
The nail is carried by the short toothed side of the guide rail which is moved in the feed direction. At this time, the nail slides or rolls on the longer teeth am of the nine opposing guide rails. As the nail rides over the longer tooth side, the guide rails are laterally displaced relative to each other. During the return stroke of the guide rail to the starting position, the nail slides on the longer toothed side of the guide rail, which moves in the opposite direction to the feed direction, and the nail slides on the longer toothed side of the guide rail, which is mounted so that it cannot move axially, i.e., moves in the opposite direction. It is fixed by the short toothed side of the rail. In this case, as the nail rides on the side surface of the long tooth, the guide rails are displaced laterally and separated from each other.

The relative movement of the two guide rails with the force required to feed the nail by one section can be caused by one partial stroke of the two guide rails in the loading direction or in the opposite direction. but,
In such a method, the magazine is expensive to manufacture and the feeding mechanism is correspondingly complex. To simplify the structure of the magazine and feed mechanism, it is advantageous to mount one guide rail so that it cannot move axially, while the other guide rail tube is movable in that direction. For this reason, the guide rails are different from each other], depending on their function, the axially movable guide rail is called a pipe transfer rail, and the axially fixed guide rail is called a pipe holding rail. The transfer rail and the holding rail are formed substantially symmetrically to each other. At least the sections in which the cutouts facing each other are arranged must be the same.

If the two guide rails are displaced laterally relative to each other during the transfer stroke or the return stroke, both guide rails simultaneously undergo a lateral displacement. Since the lateral displacement of the guide rail takes place especially against the spring force, a correspondingly large number of superimposed and balanced spring conduits must be provided. This is expensive9 and extremely prone to failure. In addition, the intermediate position of the guide rail is not accurately determined by the spring, which may cause difficulties when loading the nail into the nail groove of the device.

Therefore, in order to simplify the construction of the magazine, it is expedient for K to mount one guide rail so that it cannot move laterally, and the other guide rail so that it can move laterally. Due to the above-mentioned features, the transfer rail or the holding rail can be provided with a lateral displacement, and the other guide rail can be mounted in such a way that it cannot be moved laterally. However, in particular the transfer rails are mounted so that they cannot move laterally and the holding rails are made laterally displaceable. For this purpose, the transfer rail is movably supported in the loading direction and the holding rail in a direction transverse to the loading direction.

The transport movement of the guide rail is effected manually or by means of a special transport mechanism in the case of a magazine connected to the striking device. Particularly in pneumatically operated striking devices, the feed mechanism is driven by compressed air.

The control of the feeding mechanism can be coupled to the driving movement, so that after driving the nail, the previous driving movement in the magazine causes a feeding movement that serves to load the nail into the slot of the device. It's like a trap.

When replenishing the magazine, the guide rail is actuated in the manner described above, and the supply of nails is effected from the end of the magazine nine times away from the nail slot.

Hereinafter, the present invention will be explained in detail based on the illustrated embodiment of the tube.

The striking device shown in Figures 1-B has a barrel tube generally designated at 1. Separate nails 3 are placed in the 11-circle nail groove of the gun barrel l. The nail 1 is held by the magnet aK in the nail groove 1a.

A part of the driving piston number is shown in the rear area of the nail groove 15L. Generally, in the mounting shown as S, the plate is fixed to the barrel IK.

The magazine generally has a case indicated by 6. Case 6 has a cross section at the rear end! It has a shaped retaining strip 6a. When inserting the magazine into the device, hold it) The lip 6a corresponds to the mounting plate! It is pushed into the shaped groove 5a. The magazine is locked to the device by means of a # matching stopper at the end of the retaining strip 6a. Stop it 7
is rotatably supported around a shaft 8, and is moved by a pressure spring 9 to an output position KWI1 shown in FIG. Inside the case 6 eight opposed guide rails are arranged. Depending on the function of the guide rails of the fins, these rails are generally 1G.
and a holding rail, generally designated 11. It has a transfer rail 10 and a holding rail 11 #iυ-shaped break. The opposing free standing legs of both rails 10, 11 have tooth-shaped cutouts 1ea, IIL...tubes. The notches 16&, 11& are designed in the form of a sawtooth, with their shorter tooth side facing in the loading direction, ie towards the nail groove 1a. The body of the nail snow is disposed within the notches 10a and 111L of the transfer rail 10 and the holding rail 11. The transfer rail 1G is movable in the axial direction, is supported within the slit 6b of the case 6, and is connected to the nine sliding stones 12. bottle 1
8 protrudes from this sliding stone 12 and is fitted into the carrying two-pronged member 14. The carrying bifurcated member 14 is the cylinder 1
Driven by 5. By the actuation 9 of the cylinder 1B, the bin 18 via the carrying fork 14 and therefore the transfer rail 10 is moved by one section in the loading direction. Holding rail 1
1 is attached with a lock to prevent it from moving in the axial direction,
It can be displaced laterally. For this purpose, the holding rail 11 is connected to the guide rail 1te by bolts 16). The guide rail 17 is guided within the vertical groove 6c of the case 6. The holding rail 11 is pressed against the transfer rail 10 by a spring 18 and is supported elastically.

4th II! As shown in FIG. 1, when the cylinder 1B is actuated, the nail 2 in the notch 10aP3 of the transfer rail 10 is carried in the loading direction by the shorter tooth side of the transfer rail 10. The nailer then slides on the longer toothed surface of the holding rail 11. Since the transfer rail 10 cannot be displaced laterally, it is pushed away against the force of the holding rail llq spring 18. When the foremost nail 8 in the loading direction reaches the nail groove 1a, all the nails are placed in the notch 1 next to the holding rail 11 again.
It is brought to a height of 1a. The holding rail 11 is pushed back into the position shown in FIG. S by the pressing bar IIK.

At this time, the transfer rail 10 must be returned to the starting position shown in FIG. 2 before driving the nail 2 in the nail groove 1a. As shown in FIG. 6, the nail 3 located in the area of the holding rail 110 is stopped by the short tooth side of the notch 11a of the holding rail 11. Transfer rail 1 where nail 2 returns to starting position
0, the holding rail 11 is again pushed away in the - direction.

When the transfer rail 10 reaches the starting position shown in FIG.
The holding rail 11 can be returned to the starting position shown in FIG. 2 together with the nail Kl+ in the recess 11a. This illustrated loading process is repeated after each driving operation of the nail 8 in the nail groove 1a circle. Therefore, the magazine is moved from the rear notch of the transfer rail 10 or the holding rail 11 to the foremost notch 105L.

11 AI is too much.

When the last nail 3 in the magazine reaches the nail groove 1a, the magazine is empty and must therefore be replenished. To fill the magazine with nails 3, open the case 60 and open the hole 6d.
If you insert a nail inside, K.

will be held. In this case, after each nail insertion the transfer rail 1
0 must be activated. When the first nail 3 reaches the foremost notch 1G&or 115LK, the magazine is full. Replenishing the magazine with round and loose nails can be carried out using a vibrating device.
