Description

The invention is concerned with a variant of the detection of a projectile template in the barrel of a particular remote-controlled weapon. This device is characterized in that a sensor element is integrated in a scanning plane on the weapon and preferably electrically connected to a weapon control, wherein upon actuation or Nichtbetätigen the sensor element conclusions on the presence or absence of the bullet on the cartridge case and thus on a bullet template to be pulled. In the presence of the projectile on the cartridge case, the weapon is released by the weapon control, since then no bullet template can be present. If, however, a lack of the projectile is detected on the cartridge case, the weapon is at least blocked.

Due to, for example, manufacturing errors in cartridge ammunition, ignition failures can occur, albeit very rarely. Not excluded is that the bullet has already detached from the cartridge case and has been driven into the barrel. Now puts the bullet in the barrel, it is called a bullet template. Loading and firing a new cartridge can result in tube bursting and damage to the weapon.

In infantry weapons, the operator can even determine when removing the failure, whether the bullet is still on the cartridge case or if it is in the pipe. Such a solution is not possible with remote-controlled weapons.

The DE 10 2005 003 751 B3 describes a sleeve catcher for a bastleless ammunition. The ammunition is fed to the weapon via a conveyor and an ammunition feeder. By means of the sleeve catcher, the empty, ejected at high speed pods or ammunition (eg in a Zündversager) collected and defined in the ammunition chain of the ammunition supply again put into it. A sensor is used Here only for functional testing of the sleeve catcher, ie, the sensor permanently detects the presence of a sleeve in the laxative ammunition chain.

The DE 10 2007 048 470 A1 discloses a quick stop for a weapon drive. To be solved is the task to bring a Zündversager safely out of the gun, ie, to prevent unlocking of the closure. The quick stop is inserted when ancestors of the shutter and when a proper shot has been triggered - recoil of the weapon is done - controlled. In the case of a Zündversagers the closure moves to the non-controlled rapid stop, the unlocking is at least delayed in time.

Here, the invention has the object to show a device for detecting a bullet template in particular remote-controlled weapons.

The object is achieved by the features of claim 1. Advantageous embodiments are contained in the subclaims.

Already from the JP 2008064406 A a device is known with which the number of projectiles shot can be counted. This gauge includes two optical sensors mounted at the mouth of a gun barrel. It also determines the passing of the projectile.

From the JP 62-190399 A is a device for determining the template of stub sleeves known.

The invention is based on the idea to incorporate a device into the weapon, with which it is checked whether the bullet is still sitting on the cartridge case.

This can be done in the simplest variant by a mechanical or electronic switch, sensor, etc. This is when the bullet is still sitting on the sleeve, operated. In evaluation of this operation is then closed to the presence of the projectile on the sleeve, the further shooting is not interrupted. If the switch is not actuated, the shooting mode must be set as it must be assumed that a bullet template is used.

It is understood that other variants are possible. Thus, it is also possible to make a statement about the sensed length of the cartridge ammunition as to whether the bullet sits on the sleeve. If the length of the withdrawn cartridge is below the comparable length, the absence of the projectile is detected on the sleeve and interrupted according to this information, the shooting.

The advantage of this simple implementation of the idea is that only a small cost is associated with the simple gain in security and a complex control of the tube after a Zündversager itself is not necessary.

Reference to an embodiment with drawing, the invention will be explained in more detail. It shows:

a possible connection to the weapon.

In Fig. 1 is the basic principle of detection of a bullet template shown. In the case of a Zündversagers the cartridge is 1,1 'removed by means of the function "load" from the chamber (not shown, since known). In the most favorable case, the complete cartridge 1 is extended with projectile 2 and cartridge case 3 so that it is possible to continue firing. This necessary information is stored in a so-called scanning plane 4 on a weapon 10 (FIG. Fig. 2 ) senses. At least one sensor element 6 incorporated in this scanning plane 4, here a switch in the simplest version, is electrically connected to a weapon control 5 for this purpose. Other functionally equivalent components include Hall sensors or the like.

If there is a failure and this is pulled out of a weapon barrel 12 as a complete cartridge 1, the weapon control 5 releases the weapon 10. However, if a Munitionsversager 1 'before, ignited in which, for example, a primer (not shown) while the bullet 2 (not shown in detail, as known) driven into the barrel, the absence of the projectile 2 is detected in the scanning plane 4 and stopped firing. For this purpose, a corresponding signal is given to a weapon control 5, which blocks the weapon 10 in this situation.

Fig. 2 such as Fig. 3 show a possible connection in the scanning plane 4 at the closure end 11 of the weapon 10th

A closure 13, not shown, pulls the failure element 1,1 'out of the cartridge chamber back into a transport belt (not shown in more detail), for example by means of a feed star. If the closure 13 has reached its rear position 11, the ammunition transport 12 is introduced via a step transmission (not shown). In the ammunition transport step now a check of Zündversagers 1,1 'performed by, for example by means of the switch 6 is checked whether the projectile 2 is located on the cartridge case 3. If the switch 6 is actuated, the projectile 2 is located on the sleeve 3, the gun barrel is free, the weapon control 5 releases the weapon 10. If, on the other hand, the switch 6 is not actuated, it is assumed that no projectile 2 is located on the sleeve 3, but rather is inserted in the weapon barrel 12. Accordingly, the weapon 10 is blocked by the weapon control 5. For this purpose, the switch 6 is electrically connected to the weapon control 5, which evaluates the electrical switching signal and taken into account in the context of the functional sequence control. A message generated by the weapon control 5 can be communicated to the operator and noted in a data log.

The simplest version uses a microswitch. The actuation then takes place via a mechanical element which reduces the load on the switch 6 itself.
