Description

  The invention relates to a small art fire having the features of the preamble of independent claim 1. The invention further relates to a method of driving such a small artillery.

  In this type of small artillery with ammunition supply, shell firing is cyclically performed, i.e. several steps per cycle. When the ammunition cartridge is transported by the ammunition supply, the revolver drum rotates by one chamber position. In a revolver drum having 4 cartridge chambers or 4 chambers, the revolver drum rotates 90 degrees. The cartridge is further inserted into the revolver drum by one part distance at each turn. The ammunition cartridge finally comes to the launch position and then the cannonball leaves the barrel. The location of the ammunition supply is at the opposite angular position of the revolver drum relative to the launch position. Thus, at each moment of continuous shooting, at least three ammunition cartridges are partially in the revolver drum.

  After the end of the continuous shooting, the ammunition cartridge basically remains in the revolver drum when the weapon is stopped and all the ammunition cartridges have not been fired. Weapons are therefore "loaded" and therefore must be secured. This is effective when trying to perform a second continuous shooting immediately after the end of the first continuous shooting in individual cases. However, this is a disadvantage if, for example, in the training and teaching drive, there is no further continuous shooting after the end of the continuous shooting. In training and teaching, maintenance or teaching tasks are carried out, in particular in weapons, after continuous shooting. During this step, the ammunition cartridge remaining in the revolver drum must first be withdrawn for weapon safety, which takes time. Furthermore, it is not excluded or expected that the cartridge is damaged upon loading and is no longer provided for future use after withdrawal. Usually, these cartridges can not be reused, so they have to be disposed of at high cost, i.e. have to be exploded. At the same time, handling ammunition is a safety issue.

  In one patent document, a method is also known to load a small speed gun on the basis of the firing performance degree or according to the firing performance degree (see, for example, Patent Document 1). An ammunition cartridge is inserted into the revolver drum via the ammunition supply. The revolver drum has a plurality of cartridge chambers, each having one cartridge chamber disposed in one firing position and each having the other cartridge chamber disposed in the loading position. During loading into the chamber, the control slider is accelerated, in particular by means of a hydraulic loading device. The control slider travels to the rear end position and is again returned to the front end position by the closing spring. The revolver drum is synchronously rotated by the control curve of the control slider and the gun performs a loading cycle. In the initial position, the cartridge is usually in the ammunition supply without a belt member, from which it is transferred into the feeder of the gun. Thus, the first cartridge is in its initial position in the feeder and can be captured by the cartridge slider of the cartridge. The first cartridge is then moved into the chamber above the drum by the feeder's star wheel. This first cartridge is further rotated with the revolver drum on the rotor and completely moved by the cartridge slider into the chamber at the 9 o'clock position. Next, when the drum is rotated 90 °, the chamber having the first cartridge is further rotated to the 6 o'clock firing position. The ammunition cartridge is held and locked by an abutment bottom in the weapon housing. The weapon is thereby loaded and ready for launch. The launch of the weapon takes place immediately after the loading process and without pauses. At the same time, the weapon is first transferred to the "loaded" state just prior to launch. The time the weapon is in use and ready to be launched and not in the "protected" state is limited to a minimum or not at all. Only in and only in conjunction with the firing of the launch command is the launch performance based loading process initiated. Unloading of the ammunition takes place if, prior to that, the launch command was carried out with the launch of a weapon. When loading based on the degree of launch performance, the number of cartridges required for the launch command is provided. If the fire command has only individual fires, only one ammunition cartridge is supplied, ammunition supply to the revolver drum is interrupted and the revolver drum is further pivoted to the firing position until the ammunition cartridge reaches Ru. If the firing command has multiple shots, exactly that number of ammunition cartridges are supplied, the ammunition supply is interrupted and the revolver drum is further rotated until the last shot has been released.

  From the prior art forming the seed concept, exactly the number of ammunition cartridges are supplied for continuous shooting with a predetermined desired number of ammunition cartridges, after which the ammunition supply is interrupted and the revolver drum is It is further disclosed that it is further rotated until it is released. In order to be able to withdraw the cartridge after the continuous shooting, the small speed gun has a clutch, which is engaged during the continuous shooting. In the static, inoperative state of the weapon, this clutch can be released to separate the ammunition supply.

German Patent Application Publication No. 10201101717

  The object of the present invention is to develop a method based on a concept so that the drive of the small gun can be improved.

  This problem, which is the basis of the present invention, is solved by a small speed gun having the features of the independent patent claims and a method of driving the small speed gun accordingly.

  The ammunition supply can be functionally effectively separated from the revolver drum by means of a clutch during continuous shooting. A clutch separates the drive member, and thus the components driven by the revolver drum or the revolver drum accelerated here by the control curve of the control slider, from the ammunition supply. The clutch is arranged between the ammunition supply and the revolver drum, in particular between the ammunition supply and the star wheel, which can be driven by the revolver drum.

  Clutch engagement and disengagement are performed according to the position of the control slider. The position of the control slider is detectable by at least one sensor and can determine the launch performance of the small artillery gun based on at least one signal of the at least one sensor. The ammunition supply can be blocked by the blocking lever to facilitate reengaging the clutch. The clutch and / or the blocking lever can be switched according to the degree of launch performance and / or according to at least one signal of at least one sensor. The ammunition supply can thereby be separated by the release of the clutch during continuous shooting. This has the advantage that the ammunition supply of the weapon can be shut off during the firing of a continuous fire or a fire.

  The clutch can in particular have a clutch wheel and an inner part, and an inner part with a plurality of clutch wedges can be fitted into the internal gear of the clutch wheel. The inner part has a receptacle into which the hollow shaft is inserted. A plunger is slidably disposed linearly within the hollow shaft. The clutch wedge penetrates the receptacle in the hollow shaft and cooperates with the plunger. The radially slidable clutch wedge is pushed outward by the insertion of the plunger and thereby engages to block into the internal gear of the clutch wheel. When the clutch shaft is pulled back, the clutch wedge can be pushed back inward whereby the clutch is disengaged and the inner part and the clutch wheel can rotate at different speeds with respect to each other. The clutch is preferably operated by an electric motor. The electric motor can function functionally effectively on the lever arm, and the operation of the lever arm can move the plunger longitudinally.

  The position of the clutch is preferably detected by at least one sensor. One or two sensors can be provided, which monitor the position of the clutch or the position of the lever arm, in particular the position of the plunger. The at least one sensor can in particular be formed as an optical sensor. When this sensor "detects" the plunger, the clutch is off and the ammunition supply is completely disconnected from the drive.

  The ammunition supply, in particular the supply drive, can be blocked by the blocking lever. The blocking lever preferably cooperates with the clutch wheel. With the ammunition supply coupled, the clutch wheel is held in place by the blocking lever. This makes it possible to easily engage the clutch later. The blocking lever is magnetically operable. The clutch wheel has a plurality of spaced cuts in the circumferential surface. The cuts are equiangularly spaced relative to one another. The blocking lever engages in one of the notches in the clutch wheel.

  The clutch wheel has one cut into which the locking lugs of the blocking lever can be fitted. The notches and the locking lugs are disposed at an oblique angle to the radial direction. This ensures that the lever can be easily inserted. Furthermore, it is ensured that the blocking lever reliably blocks the clutch wheel at the beginning of the blocking time.

  During continuous shooting, the revolver drum does not rotate at a constant angular velocity. The revolver drum is stopped for a predetermined time at each step and then accelerated again. The blocking time of the drum is, for example, about 18 to 19 ms when the weapon is driven at a firing performance of about 1000 shots per minute. The separation must take place exactly within this block time in order to be able to carry out the separation. Otherwise, the drive member is mechanically tightened, and there is a risk that the force to unclutch may be too high, thus the danger of damaging the weapon. Furthermore, the inability of the kinetic energy in the ammunition supply to bring about further movement of the weapon in the cycle and the supply of other ammunition must be prevented. It is therefore necessary that the blocking lever be separated and inserted reliably in this short time window.

  To that end, the position of the control slider is detected as accurately as possible by at least one sensor. Preferably the position of the control slider is detected by two sensors. These sensors provide a step signal as soon as the control slider is within the area of the respective sensor. The control slider moves bi-directionally linearly between two end positions. In one end position "front", the control slider is located near the tail plug, and in the other end position "back", the control slider is located near the ammunition supply. The front sensor determines whether the control slider is located at the front position ("front") and the rear sensor preferably determines whether the control slider is located at the rear position ("back") taking measurement. The small speed gun is preferably a gas powered small speed gun. The launch performance of this gas-powered vandal may change from launch to launch, so the time to the fall of the signal "slider / front" of the front sensor is sufficient with only one sensor It can not be predicted accurately. The switching time of the clutch motor is, for example, about 30 ms, which is longer than the block time of about 18 ms. The motor must therefore be switched long before the start of the block time. It is therefore advantageous to additionally provide a rear sensor, which detects the position of the control slider in the rear position. The rear sensor also provides a step signal on the temporal progression of the control slider at this rear position. The position of the control slider "in front" and the position of the control slider "back" are also detected so that from the side of the signals of the two sensors, a very good prediction for the launch performance of the weapon between individual launches Can be determined.

  The back sensor for control slider position / back is formed identical to the front sensor for control slider position / front. These sensors can, for example, be designed as contact switches, which have the advantage that they are very simple and very well formed. In an alternative form, the sensor can be formed as a waveguide sensor or as a magnetic sensor.

  The period or firing performance determined using the sensor is multiplied by the factor previously determined and stored, which causes the timer signal for the clutch switching process to be sufficiently early in the cycle, ie A switching signal of about 30 ms ensures that the clutch is released within the block time of the revolver drum. The clutch is preferably released within the first third of the cycle.

  In addition, the blocking lever is driven. This is done by the start signal according to the side of the signal of the front sensor. The switching time of the blocking lever magnet is about 10 ms. The switching length of the blocking lever is about 37 ms. The blocking lever preferably abuts the circumferential surface of the clutch wheel with a predetermined pressing force before the blocking time is still started. This facilitates blocking of the clutch wheel.

  If the clutch sensor indicates that the clutch has not been released during the blocking time, the blocking lever is released again and the clutch process is repeated one cycle later or is completely interrupted. This prevents damage to the blocking lever which is fitted into the clutch wheel. The clutch wheel rotates synchronously on the same axis as the revolver drum while the clutch is engaged.

  The blocking lever is driven by current control. The angular resistance changes with the ambient temperature but the switching length remains unaffected by the current control.

  The method is characterized by the following method steps:

  A sensor signal is detected to detect the position of the control slider. Thereafter, the launch performance predictions are calculated continuously during continuous shooting. Before terminating the volley firing as desired, a timer signal or period for operating the clutch motor is calculated. In a four-chamber drum, these three shots are performed before the desired end of the blast, so a timer signal is calculated during the last fourth shot of the blast. An on signal for the blocking lever is formed. A declutching signal is output. After that, the blocking lever contacts the circumferential surface of the clutch wheel to block the clutch wheel. During the block time, the revolver drum stops rotating. The blocking lever engages into the clutch wheel and the clutch motor releases the clutch.

  This measure allows the connection and block to be performed not only statically for unloading but also dynamically during the bombardment. The present invention improves weapon safety and reduces driving costs.

  There are numerous possibilities of forming and developing the small speed gun according to the invention and the method according to the invention. For that, first of all, reference may be made to the claims that are arranged after the independent patent claims. Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings and the accompanying description.

  FIG. 1 shows a portion of a small speed gun. The small speed gun has a gas drive, not shown in detail, which is used to drive the control slider 1. The control slider 1 slides linearly with the gas drive and cooperates with the revolver drum 2 via a control curve which is not shown in detail. The revolver drum 2 has a plurality of chambers 3, 4, 5, 6. In the illustrated embodiment, there are four chambers 3, 4, 5, 6 or 4 chambers. However, it is also conceivable for the revolver drum to have more or less than four chambers. A control curve, not shown in detail, cooperates with the revolver drum 2 via the circumferential surface of the revolver drum 2 so that the revolver drum 2 is pivoted by one angular position each. When the revolver drum 2 has four chambers, the revolver drums 2 are each rotated by 90 °. Furthermore, FIG. 1 shows the cartridge 7 in a partially inserted state. This ammunition cartridge is disposed at the 12 o'clock position. When the revolver drum 2 is rotated by 90 ° in each clock, the cartridge 7 is inserted one by one until it reaches the lower or 6 o'clock firing position. The ammunition cartridge 7 is supplied via the ammunition supply 8 and placed on the star wheel 9. The star wheel 9 is driven by the revolver drum 2 via the shaft end 10. The star wheel 9 is connected non-rotatably to the revolver drum 2.

  This arrangement is configured such that the ammunition supply 8 of the weapon can be stopped during continuous shooting. During continuous shooting, preferably a plurality of shots are released and a corresponding number of ammunition cylinders are provided until the clutch 11 is released. It is known that only one ammunition cartridge is supplied during continuous shooting and then the clutch 11 is already released. The drive of the ammunition supply 8 is therefore interrupted via the clutch 11. Here, the clutch 11 is arranged between the star wheel 9 and the ammunition supply 8. The clutch 11 has a clutch wheel 12. The clutch wheel 12 is connected non-rotatably to the supply transmission mechanism 13 of the ammunition supply 8. Furthermore, the clutch 11 has an inner portion 14 that fits into the clutch wheel 12. Next, FIGS. 3 to 8 will be described in detail. The revolver drum 2, the star wheel 9 and the inner part 14 form the drive side. The clutch wheel 12 is associated with the driven side of the clutch 11. The clutch 11 can be driven by a motor, in particular an electric motor 15. By means of the electric motor 15 the lever arm 16 is pivotable, which results in the disengagement and coupling of the clutch 11.

  This will be described in detail with reference to FIGS. The clutch wheel 12 is mounted on the hollow shaft 17 and the inner part 14 is likewise mounted on the hollow shaft 17. The hollow shaft 17 is connected non-rotatably with the revolver drum 9 via a star wheel 9 and has external gear teeth 18 at the appropriate axial end. Here, the inner part 14 has clutch wedges 19 spaced apart on the circumferential side, which are arranged slidably in the radial direction. The clutch wedge 19 penetrates an unshown opening in the external gear of the hollow shaft 17 thereby forming a non-rotatable connection between the inner part 14 and the hollow shaft 17. The clutch wedge 19 can also be called a blocking member or a blocking block. Here, although four clutch wedges 19 are provided separately on the circumferential surface, in another embodiment, more or fewer clutch wedges 19 may be disposed on the circumferential surface separately. A plunger 20 is slidably disposed in the hollow shaft 17. The plunger 20 is biased such that the clutch wedge 19 is pushed outward by a head not shown in detail of the plunger 20 by means of a spring not shown in detail, whereby the clutch wedge 19 is inside the clutch wheel 19. Insert into the gear cut. The lever arm 16 operates the plunger 20 to bring about linear movement of the plunger 20 so that the corresponding head of the plunger 20 can be pulled back and the clutch wedge 19 can be pushed radially inwards, as shown in FIG. Thus, the clutch 11 is released.

  Two sensors 21, 22 are shown in FIGS. These clutch sensors 21, 22 are formed as optical sensors 21, 22. These sensors 21, 22 monitor the position of the free end of the plunger 20. If the sensors 21, 22 do not detect an axis (see FIG. 9), the plunger 20 is fitted in such a way that the clutch wedge 19 blocks the connection between the inner part 14 and the clutch wheel 12. Therefore, the clutch 11 is inserted. In the configuration shown in FIG. 10, the sensors 21, 22 detect the free end of the plunger 20, and the plunger 20 is pulled back so that the clutch wedge 19 can be pushed back in, so the clutch 11 is released ing.

  Next, FIGS. 4, 5 and 11 will be described in detail. The clutch wheel 12 can be blocked by the blocking lever 23. The blocking lever 23 can also be referred to as a block-feed-lever. The blocking lever 23 holds the position of the clutch wheel 12 when the clutch 11 is released. As a result, clean binding is possible again later. The blocking lever 23 is operated in particular by means of the magnet 25 and is inserted into the notches 24 provided on the circumferential surface. The corresponding magnet 25 is shown diagrammatically in FIGS. 3, 4 and 5. The blocking lever 23 has a locking lug 26 which can be inserted into the incision 24.

  The shape of the incision 24 and the locking lug 26 are shown in detail in FIG. It can be clearly seen that the locking lugs 26 do not extend purely radially of the clutch wheel 12 and the incisions 24 likewise have wall regions 27, 28 which do not extend purely radially. The locking projection 26 extends at an acute angle with respect to the radial direction when viewed with respect to the rotational axis of the clutch wheel 12. The locking lugs 26 and at least one of the wall regions 27 can extend at an angle of approximately 10 °, in particular with respect to the radial direction. The other wall region 28 can be inclined at another angle, for example 3 °, to the radial direction, or can extend radially. The incisions 24 are formed asymmetrically with respect to the incisions 24. The locking lugs 26 in particular abut the wall area 27 when the locking lugs 26 are fitted into the incisions 24. The position of the blocking lever 23 is detectable by the sensor 29. The locking status is monitored by the sensor 29.

  Next, the method will be described in detail using the diagram of FIG. The diagram shows the position of the control slider 1 in the form of a slider track 30 written over time t. As already explained, the revolver drum 2 is moved according to the position of the control slider 1. The revolver drum 2 is stopped between time points 31 ("start of block time") and 32 ("end of block time"). This is referred to as block time. Time point 31 indicates the beginning of the block time, and time point 32 indicates the end of the block time. During the continuous shooting, the revolver drum 2 does not rotate at a constant speed, but rather the revolver drum 2 is stopped at each step during the block time and then accelerated again. The block time of the revolver drum 2 is, for example, about 18 to 19 ms when the weapon is driven at a launch performance degree (Kadenz) of 1000 shots per minute. In order to decouple the ammunition supply by means of the clutch 11, the clutch 11 must be released within the blocking time, ie between the points 31 and 32. If the clutches 11 are not released during the blocking time, there is a risk that the drive members are mechanically tightened against one another, whereby the separating force of the clutches 11 is too high and the risk of damage to the weapon is imminent Do. Furthermore, the inability of the kinetic energy of the ammunition supply 8 to provide for further movement of the weapon and the supply of other ammunition within the cycle must be prevented. It is therefore necessary that the disengagement of the clutch 11 and the insertion of the blocking lever 23 take place within a short window of blocking time.

  The exact position of the slider, ie the slider trajectory 30, is unknown and is approximately detected by the two sensors. A front sensor and a rear sensor are provided. The front sensor monitors whether the control slider 1 is located in the front area, ie in the vicinity of the tail plug or barrel. The rear sensor monitors whether the control slider is in the rear region. The signal of the front sensor is entered in FIG. 12 as SV (slider / front). The signal of the rear sensor is marked as SH (slider / rear). The two signals SV and SH are step signals. When the two signals SV and SH are equal to one, the control slider 1 is in the forward position and thus within the block time. If the two signals are equal to zero, the control slider 1 is in the rearward position. At time points 33, 34, the signals SV and SH change, which is common to the relevant aspects. The time difference between time points 33 and 34 is a good measure to evaluate the launch performance of the weapon for the next individual launch. The use of two sensors here improves the evaluation of the launch performance of the weapon for the next individual launch, which improves the prediction of the next block time. This reduces the risk of damage to the weapon due to miscalculation of block times. The use of only one of the signals SV or SH to calculate the degree of launch performance is of course not satisfactory. Because the degree of launch performance of the gas-powered weapon varies from launch to launch, the length of time until the fall of the signal SV can not be predicted sufficiently accurately.

  The switching market value of the clutch motor 15 is about 30 ms, which is longer than the block time of about 18 ms. The clutch motor 15 must therefore be switched long before the start of the block time. The period 35 between the sides at the points 33 and 34 is here characterized by braces. This period 35 is determined in advance and multiplied by a stored factor, which causes the timer signal for the clutch switching process to be early enough in the cycle, ie about 30 ms of switching time for the clutch to drum It is provided to ensure opening within the block time, preferably within the first third of the block time. The point in time at which the clutch is operated is indicated here by reference numeral 36. The period between time points 34 and 36 is linearly proportional to period 35.

  Thus, the launch performance prediction is calculated continuously during continuous shooting, and a period for operating the clutch motor 15 is calculated before the end of the continuous shooting, which depends on the launch performance prediction. There is. In order to be able to release the clutch 11 at the correct time within the blocking time, the on signal for the blocking lever 23 and the disconnecting signal for the clutch 11 are output at the correct time before the blocking time.

  Furthermore, the blocking lever 23 is driven. This is done by the start signal starting at time point 33. The switching time of the magnet is about 10 ms. This ends at time 37. The subsequent switching length can be, for example, 37 ms. At time point 38, the locking projection 26 of the blocking lever 23 abuts on the circumferential surface of the clutch wheel 12, and at time point 39 the blocking lever 23 is fitted. Time point 39 corresponds to the start 31 of the block time.

  As shown in FIGS. 9 and 10, two sensors 21 and 22 for monitoring the position of the plunger 20 are provided. Sensor 21 first detects plunger 20 and second sensor 22 detects the plunger at time 41. At time 41, the clutch is completely released. If, at time point 40, the first sensor 21 does not supply any signal, the magnet 25 is switched off for safety, so that the blocking lever 23 is released and within the blocking time the clutch wheel 12 and the blocking lever 23 are The locking connection between them is nullified.
