Definitions

  • the invention relates to a holding device for ammunition bodies according to the preamble of patent claim 1. Furthermore, the invention relates to a magazine with a holding device, a projectile lift with a holding device and a method for holding ammunition bodies.
  • Such holding devices are used, for example, in ammunition magazines to keep the corresponding ammunition bodies safely in a storage location.
  • ammunition bodies can slip or become jammed, which can be prevented by appropriate holding devices.
  • such holding devices usually have two movable holding shells that form a holding area in which an ammunition body can be held.
  • the holding area is located between the two holding shells and, when the holding device is closed, corresponds to the cross-section of the ammunition body being held.
  • one or possibly both holding shells can be rotated back and forth about a rotation axis between a closed or holding position and an open or transfer position, and the holding device is thus designed like a holding tongs.
  • the holding tongs are open, ammunition bodies can be inserted into or removed from the holding tongs, and when the holding tongs are closed, the ammunition body is held between the two holding jaws or the holding shells of the tongs and can then no longer be moved relative to the holding device.
  • the DE 30 46 642 A1 discloses an automatic loading device for firearms in which the ammunition is kept ready in magazines, with two magazines arranged symmetrically to the longitudinal center plane of the weapon, from which the ammunition can be optionally removed.
  • the DE 30 25 501 C1 discloses a device for automatically loading a cannon stored in a rotating tank turret of a battle tank vehicle with large-caliber ammunition.
  • the invention has for its object to provide a holding device for ammunition bodies with a reduced space requirement and a corresponding method for holding ammunition bodies.
  • This design allows the holding device to be opened and closed with less space required. Because the rotation axis of the holding shell runs through the holding area, the distance between the longitudinal axis of the ammunition body and the rotation axis of the holding shell is reduced compared to the pliers solution and thus the space required for opening is also reduced. The holding shell therefore does not have to be moved as far away from the ammunition body to open and close the holding device.
  • both holding shells can be rotated around a common axis of rotation. This enables the holding device to be opened and closed quickly or the holding shells to be rotated quickly between the holding position and the transfer position.
  • the rotation axis of the holding shell is aligned with the longitudinal axis of a held ammunition body.
  • This design allows the holding device to be opened and closed without requiring additional space.
  • Both holding shells can move in a round contour when opening and closing and the distance between the holding shells and the rotation axis can remain constant.
  • the rotation axis can run through the middle of the holding area. Since ammunition bodies are rotationally symmetrical, the holding area also has a correspondingly round contour that can match the outside diameter of the ammunition bodies.
  • the holding device can hold the ammunition bodies lying down.
  • the ammunition bodies lying down In magazines in military vehicles in particular, it has proven to be a good idea to arrange the ammunition bodies lying down, as the ammunition bodies are then much easier to access than if they were stored upright.
  • lying ammunition bodies in a military vehicle usually already point in the firing direction, so that the ammunition bodies can be inserted into the gun barrel relatively easily and do not have to be rotated 90 degrees in elevation first.
  • the holding shells it has proven to be advantageous if these are designed in the form of cylinder segments. It is advantageous if the center axes of the cylinder segments correspond to the axis of rotation. This design enables reliable accommodation of ammunition bodies, since these are also designed in a cylindrical shape.
  • segment angle refers to the angle that the connection of one end of a holding shell in cross section with the axis of rotation forms with the connection of the corresponding other end with the axis of rotation.
  • the corresponding connections are each at a right angle to the axis of rotation.
  • the segment angle must therefore be large enough so that even ammunition bodies with a greater weight can be safely picked up and held.
  • the sum of the segment angles of the two holding shells is between 90 and 180 degrees, preferably between 140 and 180 degrees. particularly preferably between 170 and 180 degrees, and most preferably between 175 and 180 degrees.
  • the holding shells have different segment angles.
  • the holding shell with the larger segment angle can bear more weight than the holding shell with the smaller segment angle.
  • the holding shell with the larger segment angle can be arranged below the ammunition body in the holding position and the holding shell with the smaller segment angle can be arranged above the ammunition body.
  • the segment angle of one holding shell can be between 90 and 175 degrees, preferably between 100 and 160 degrees, particularly preferably between 110 and 140 degrees and very particularly preferably between 115 and 130 degrees. In practice, a segment angle of 120 degrees has proven to be advantageous.
  • the segment angle of the other holding shell can be between 30 and 100 degrees, preferably between 40 and 80 degrees and particularly preferably between 50 and 70 degrees. In practice, 60 degrees has proven to be advantageous.
  • the two holding shells can be rotated relative to one another about the axis of rotation.
  • the two holding shells In order to open the holding device and move it into the transfer position in which the ammunition bodies can be introduced into the holding device or into the holding area, the two holding shells can be moved relative to one another about the axis of rotation.
  • the two holding shells In order to close the holding shell that is open and in the transfer position so that the ammunition body is then held in the holding shell or in the holding area, the two holding shells can be moved in opposite directions.
  • a holding shell drive offers advantages over moving the holding shells with two drives, particularly in terms of costs.
  • the use of just one drive also reduces the probability of failure.
  • the movements of the holding shells can be positively coupled, so that a movement of one holding shell leads to a movement of the other holding shell.
  • the two holding shells cannot then be moved freely and independently of one another, resulting in fixed holding positions and transfer positions.
  • the coupling also prevents one of the two holding shells from moving in an unintentional manner and thus reduces the risk that an ammunition body is not held securely in the holding position or cannot be removed from or inserted into the holding device in the transfer position.
  • the two holding shells can be moved in opposite directions. For example, if one of the holding shells is rotated clockwise around the axis of rotation, the other holding shell can be rotated anti-clockwise.
  • the holding shell drive is connected to both holding shells via a gear.
  • the gear can ensure that the two holding shells can be moved in opposite directions relative to each other with just one drive.
  • the gear is arranged at one end of the holding shells.
  • the gear is thus easily accessible from the outside, which simplifies maintenance.
  • the gear can be arranged at the end of the holding shells in which the rear end of the ammunition body is accommodated. In this respect The gear can then limit the holding area to the rear.
  • the holding shells can be mounted on a pivot bearing at the opposite end area. With such a bearing on both sides of the holding shells, the forces acting can be reliably absorbed.
  • the holding area or the held ammunition bodies can be located between the two holding shells and between the pivot bearing and the gear. In this respect, the ammunition bodies are then securely held in the holding device in every direction in the holding position and cannot move.
  • a planetary gear enables the two holding shells to move in opposite directions around a common axis of rotation with just one drive in a structurally simple manner.
  • the planetary gear can have a ring gear with internal teeth and a sun gear with external teeth. Between the ring gear and the sun gear, several planet gears can be provided that mesh with the ring gear and the sun gear. Three evenly distributed planet gears have proven to be advantageous for even power transmission.
  • the sun gear and the ring gear can both be rotatable about the axis of rotation.
  • the planet gears can be mounted on a web and connected to each other so that they cannot move relative to each other.
  • the holding shell drive can be connected to the web, for example via a screw connection. If the sun gear rotates in one direction the rotation axis is rotated, the planet gears ensure that the ring gear rotates in the opposite direction.
  • the ring gear can be connected to one of the holding shells and the sun gear can be connected to the other holding shell, so that both holding shells can then rotate in opposite directions around the rotation axis.
  • the two holding shells can be rotated together about the axis of rotation via a rotary drive. This enables a wider range of uses for the holding device. By rotating them accordingly, it is also possible for ammunition bodies to be introduced into the holding device from any direction in the transfer position or for ammunition bodies to be ejected from the holding device in any direction. Furthermore, the two holding shells can be transferred to a gripping position in the transfer position by rotating them together about the axis of rotation and aligned so that they can grip an ammunition body from above.
  • the ammunition body is secured in the holding device and can then be moved, for example together with the holding device.
  • ammunition bodies can also be gripped with the holding device and the holding device can be designed like a gripper.
  • the gripping position therefore corresponds to a transfer position in which both holding shells have been rotated together by 90 degrees about the axis of rotation.
  • ammunition bodies can be removed from the holding device in any direction, especially to the right and to the left. ejected. This is particularly advantageous when the holding device is used in a projectile lift or in a magazine.
  • the two holding shells can be rotated together around the axis of rotation without moving relative to each other, i.e. without relative movement.
  • the rotary drive can rotate the holding shell drive, the gear and both holding shells together around the axis of rotation.
  • the planetary gears of the gear can be coupled to the rotary drive via the web.
  • the web can be connected, for example, to a gear ring that can be rotated by the rotary drive.
  • the rotary drive can be arranged above the holding shell drive.
  • the two holding shells are opposite each other in a holding position such that an ammunition body is held between the two holding shells, and the two holding shells are arranged in a transfer position such that an ammunition body can be ejected from the two holding shells.
  • the ammunition body can lie in one of the two holding shells, in particular in the larger holding shell, and the other holding shell can lie opposite the holding shell and thus secure the ammunition body.
  • the ammunition bodies can be held in a form-fitting manner.
  • the two holding shells are then arranged on opposite sides of the ammunition body. In order to remove the ammunition body from the holding device or to eject it from the holding device, the two holding shells can be moved into the transfer position in which the ammunition body is no longer secured.
  • the two holding shells are in contact with each other in the transfer position.
  • This position The two holding shells ensure that ammunition bodies can be removed from the holding device or inserted into the holding device.
  • the positive connection is eliminated.
  • the two holding shells can be in contact with one another, but the two holding shells can also be in contact with one another in the transfer position in such a way that they are at least partially arranged one behind the other and overlap. Since the gripping position is basically just a rotated transfer position, the two holding shells can be in contact with one another in the gripping position.
  • one of the holding shells has an ejection device for ejecting an ammunition body.
  • a certain force can be applied to an ammunition body via the ejection device, which makes it easier to remove or eject the ammunition body.
  • the ejection device can be designed as an ejection latch and in particular as a spring. Because it is designed as a spring, no additional activation or electrical energy is required to eject the ammunition body from the holding device.
  • the ammunition body can pre-tension the ejection device so that it then ensures that the ammunition body is ejected from the holding device when the holding shells are moved into the transfer position.
  • the ejection device can be arranged in the holding shell with the larger segment angle, since the main load of the ammunition body can rest on this holding shell. It is advantageous if the ejection device is arranged in the area of the center of gravity of the ammunition body, i.e. in particular in the middle of the holding shell. It is also possible to provide several ejection devices distributed over the length of the holding tray. This allows a reliable ejection of the ammunition body to be achieved without it tilted. The longitudinal axis of the ammunition body then remains parallel to the axis of rotation of the holding shells.
  • an ejection mechanism is provided with at least one ejection latch and an ejection drive for moving the ejection latch.
  • the ejection latch can be moved via the ejection drive and the ammunition body can then be ejected from the holding tray.
  • the ejection mechanism can be designed in such a way that the ejection latch can be actuated via a relative movement of the holding rollers.
  • the ejection latch can thus be positively coupled to the holding rollers in such a way that the ammunition bodies are ejected automatically when the holding rollers assume a predefined position, in particular the transfer position.
  • the ejection latch can have two latch members that are pivotally connected to the holding tray at one end and that are pivoted to eject an ammunition body. It is advantageous if the two latch members are pivoted towards each other or at least one latch member is pivoted towards the other latch member. For example, one latch member can be pivoted clockwise and the other latch member anti-clockwise. At the end not connected to the holding tray, the latch members can have rollers that can ensure that the ammunition body is reliably ejected and does not jam. When the ammunition body is in the holding tray, the ends of the latch members or the rollers can be in contact with the lower half of the ammunition body, so that when the latch members are pivoted, the ammunition body is moved away from the holding tray in which the latch members are mounted.
  • the ejection mechanism is designed in such a way that the ammunition bodies are ejected in a certain direction, independent of gravity.
  • the ammunition bodies can therefore be ejected from the holders not only downwards, but also sideways and, to a certain extent, upwards.
  • the ejection latch protrudes beyond the edge of the lower holding tray.
  • the ejection latch can therefore have a larger segment angle than the holding tray, in particular than the holding tray with the larger segment angle.
  • the ammunition body can also be additionally secured in the holding tray by the ejection latch.
  • One ejection latch can be provided for the rear area of the ammunition body and two ejection latches for the front area of the ammunition body.
  • the ejection drive has a toothed segment coupled to one of the two holding shells and an ejection pinion rotatably connected to the other holding shell, wherein when the holding shells move relative to one another, the toothed segment rotates the ejection pinion and thereby actuates the ejection pawl.
  • the ejection of the ammunition bodies can thus be positively controlled by the relative movement of the holding shells. No additional motor is required to drive the ejection pawls.
  • the ejection pinion can be rotationally coupled to one or more ejection pawls, for example via a rod coupling.
  • the ejection pinion is rotationally coupled to at least one pawl member, so that when the holding shells move relative to one another, the ejection pinion rotates
  • the ratchet link is also rotated accordingly and the ammunition body is thus basically ejected automatically.
  • the toothed segment can be designed in such a way that it does not actuate the ejection pinion in a certain rotation range of the holding shell, and actuates the ejection pinion in another rotation range.
  • the holding shells can thus be moved relative to one another in a certain range without the ejection pawls being activated. This means that the ammunition body can only be ejected when the holding shells have been rotated far enough.
  • the ejection pawls are then only activated in this last pivot range.
