Definitions

  • the invention relates to a projectile lift for the vertical movement of ammunition bodies between two storage levels of a magazine with a receiving tray for receiving an ammunition body and a holding device for holding the ammunition bodies.
  • projectile lifts can be used with which the ammunition bodies can be automatically moved back and forth between the different storage levels.
  • the projectile elevators can have a receiving shell onto which the ammunition bodies can be pushed when the magazine is refilled with ammunition. Thereafter, the ammunition bodies can then be moved to the appropriate storage level.
  • the holding device can, for example, be arranged on the side of the receiving shell and at least partially encompass the ammunition bodies for securing, so that these can no longer move laterally and in the vertical direction. Problems arise, however, when the ammunition bodies are to be ejected from the side of the projectile elevator or are to be introduced into the projectile elevator from the side. Although the ammunition bodies can be pushed out of the receiving shell in the longitudinal direction when the safety device is released, the safety device can make it more difficult for the ammunition bodies to be pushed out laterally and thus make it difficult for the ammunition bodies to move between the storage levels.
  • the DE 199 13 283 C2 discloses a magazine with an elevator having a loading tray on which ammunition bodies can be accommodated.
  • the object of the invention is to specify a projectile lift that enables the ammunition bodies to be moved easily between the different storage levels and a corresponding method for the vertical movement of ammunition bodies.
  • a projectile lift according to claim 1 in which the holding device can lift an ammunition body vertically from the receiving tray.
  • the ammunition body By raising the ammunition body, it is not necessary for it to be ejected from the side of the receiving shell, but the ammunition body can be pushed onto the receiving shell and then gripped by the holding device, for which purpose the holding device can be transferred from a gripping position to a holding position.
  • the holding device can then be raised vertically together with the ammunition body and then brought into a transfer position in which the ammunition body can be ejected from the holding device and fed to the corresponding storage level.
  • the receiving shell it has proven to be advantageous if the ammunition bodies can be pushed onto the receiving shell in the longitudinal direction.
  • the receiving shell can be open at the front and at the rear end, so that ammunition bodies can be pushed onto the receiving shell from behind and pushed out of the receiving shell towards the front.
  • the receiving shell can serve as a linear guide for the ammunition bodies, so that they are held securely in the receiving shell and cannot be ejected laterally from the receiving shell.
  • the receiving shell can be in the form of a segment of a cylinder and the inner diameter of the receiving shell can be adapted to the largest diameter of the ammunition body. Usually this will be the diameter at the bottom of the ammunition body. This enables the ammunition bodies to be guided securely in the receiving shell.
  • the longitudinal axis of the ammunition body corresponds to the longitudinal axis or the cylinder axis of the receiving shell when it is lying on the receiving shell.
  • the cradle can be longer than the ammunition bodies so that they do not protrude over the cradle.
  • the receiving shell can essentially have the same length as the holding device or as the holding shells of the holding device.
  • the holding device and the receiving tray are arranged parallel to one another. This configuration ensures that an ammunition body located on the receiving tray can be reliably gripped and lifted from the holding device. The ammunition body does not have to be rotated or pivoted for this. At the same time, it is also ensured that the ammunition body can be placed on the receiving tray in order then, for example, to be able to be moved into a removal position in which the ammunition body can be ejected from the magazine.
  • the holding device may have an axis of rotation and the axis of rotation may be parallel to the longitudinal axis of the receiving tray.
  • the holding device can be moved in the vertical direction relative to the receiving shell. This configuration makes it possible for the distance between the holding device and the receiving shell not to be constant, but for the holding device to be able to move towards the receiving shell, for example in order to receive and lift an ammunition body from the receiving shell.
  • the holding device can lift the ammunition body from the receiving tray in the manner of a gripper and place it on the receiving tray. Due to the gripper-like configuration, the holding device can lift an ammunition body upwards out of or from the receiving shell and it is not necessary for the ammunition body to also be able to be slid onto the holding device. The actual movement of ammunition bodies between storage levels can thus be taken over by the holding device and the receiving tray allows the ammunition bodies to be pushed into the projectile elevator.
  • the receiving shell has one, in particular two, recesses.
  • One, in particular two, projectile supports can be provided, which can be arranged, for example, on the floor of the projectile elevator or the magazine.
  • the projectile support can extend through the recesses and hold part of the ammunition body.
  • the configuration and the position of the projectile support can be adapted to the contour of the ammunition body. This is because this is generally narrower in the front area than in the rear area, so that the projectile support can support the ammunition body, particularly in the front area.
  • the projectile support can also ensure that the holding device can reliably grip the ammunition bodies and then lift them off the receiving shell.
  • the holding device In order to move the holding device, it has proven to be advantageous if it can be moved in the vertical direction via a linear drive.
  • the holding device can be moved up and down via the linear drive and moved to any storage level.
  • the linear drive enables an exact position control of the holding device, so that the ammunition bodies can be reliably lifted from the receiving shell or placed on it and the various storage levels can be approached with precision.
  • two linear drives are provided, one linear drive on one side of the holding device and the other linear drive on the other side of the Holding device can be arranged.
  • These two linear drives ensure that the holding device remains as straight as possible during a vertical movement, so that the ammunition body cannot move unintentionally due to a tilted position.
  • the weight of the ammunition body located in the holding device can be evenly distributed by two linear drives. It is advantageous if one linear drive is arranged on one end area of the holding device and the other linear drive is arranged on the other end area. The holding device can then extend between the two linear drives.
  • the linear output it has proven to be advantageous if it has at least one, in particular two, rotatable threaded spindles, which move the holding device in the vertical direction when rotated.
  • a lead screw By using a lead screw, the position of the holding device can be controlled very precisely.
  • the movement of the holding device can be dependent on the direction of rotation of the lead screw, e.g. the holding shell can be moved up when the lead screw is rotated clockwise and down if the lead screw is rotated counterclockwise.
  • Two threaded spindles allow the acting forces to be evenly distributed, which improves the overall stability of the bullet lift.
  • the threaded spindles are arranged parallel to one another and extend perpendicularly to the longitudinal axis of the ammunition body or perpendicularly to the holding device. Furthermore, it is advantageous if both linear drives each have two threaded spindles, so that the holding device can be moved up and down by a total of four threaded spindles. This ensures that the holding device is supported particularly evenly.
  • the threaded spindles of a linear guide can be rotatably mounted in a bearing rail at the lower end, so that they do not move, but also retain a fixed, defined position during rotation.
  • the two threaded spindles can also be connected to one another via a corresponding bearing rail at the upper end of the threaded spindles, on which the lifting motor and the gear mechanism can be arranged.
  • the linear drive can then have a rectangular shape.
  • the linear drive has a guide element which is arranged on the threaded spindle in the manner of a spindle nut.
  • the guide element can be moved up and down by turning the threaded spindle.
  • the guide element can be connected to the holding device, in particular the holding device is rotatably mounted in or on the guide element.
  • the guide element can be arranged on both threaded spindles of a linear drive and to this extent connect the two threaded spindles with one another.
  • the guide element can have two threaded bores through which the two threaded spindles can extend, the threads being able to mesh with one another in such a way that the guide element can be moved in the vertical direction. It is advantageous if two guide elements are provided, one for each linear drive.
  • the holding device can then be rotatably mounted on both sides in or on a guide element.
  • a lifting motor which can drive the threaded spindle, in particular both threaded spindles of a linear drive, via a gear.
  • the lifting motor can be arranged at the upper end of the linear drive so that it does not impede the movement of the holding device.
  • the lifting motor can be connected to the two threaded spindles of a linear drive via a gear, so that the two threaded spindles are always connected rotate synchronously. This prevents the guide element from jamming due to uneven rotation of the threaded spindles.
  • a separate lifting motor can be provided for each linear drive. Both lifting motors can be coupled to one another, in particular via a corresponding control, so that all four threaded spindles rotate synchronously.
  • the receiving tray can be moved in the vertical direction.
  • ammunition bodies can be pushed onto the receiving shell in different levels and pushed out of the receiving shell again in different levels. For example, it may be desirable to reload the ammo depot at the lowest level but retrieve the ammunition at a higher level.
  • the receiving tray can then be moved to the desired loading position and the ammunition bodies can then be lifted off the receiving tray via the holding device and then stored. If an ammunition body is to be removed from the magazine, it can be placed on the receiving tray by the holding device.
  • the receiving shell can then be moved into the removal position and the ammunition body pushed out at the desired location.
  • the movement of the receiving shell thus allows a variable ammunition and removal of ammunition bodies in different levels.
  • the projectile lift can therefore also be used for existing magazines and vehicles and can also serve as a retrofit solution.
  • the receiving tray and the holding device are coupled to one another in such a way that the receiving tray can be moved together with the holding device when the holding device is inside or above a boundary plane.
  • the boundary level is the second storage level. Stock levels are counted from the bottom, with the lowest level equal to the first level. If the holding device is moved upwards, for example, and thereby exceeds the boundary level, the receiving tray is moved accordingly. The holding device and the receiving tray are then coupled and they move in unison with the same distance in the vertical direction.
  • both the receiving device and the holding device can be moved to the lowest storage level.
  • the holding device can be moved below the boundary plane independently of the receiving tray.
  • the receiving tray may be in the lowest level when the fixture is in the boundary level.
  • the receiving tray When the fixture is within or above the boundary plane, the receiving tray may be below the fixture at a distance of the boundary plane from the lowest level. If the second storage level is the border level, the distance between the receiving tray and the holding device is then the distance of the border level from the lowest storage level.
  • the receiving shell is coupled to the holding device via a linear guide. Due to the linear guide, the receiving shell can be moved in the vertical direction together with the holding shell via the linear drive.
  • the receiving tray does not require its own drive, but is moved by the lifting motor or the lifting motors of the linear drives.
  • the linear guide can be designed as a vertical strut that can extend parallel to the threaded spindle. It is advantageous if two, in particular four, linear guides are provided so that the receiving shell can be moved safely in the vertical direction, even if an ammunition body is resting on it. Two of the four linear guides can be connected to an end area of the receiving shell. Furthermore, it is possible for two linear guides to be connected to one another, in particular via a U-shaped connection. This design allows the receiving shell to rest on the connection between the two linear guides, which increases stability. Furthermore, it is advantageous if the linear guide is guided in the guide element.
  • the guide element can slide over the linear guide, so that the receiving shell is not moved as well.
  • the linear guide it is proposed that it have a stop that limits a movement of the holding device relative to the receiving shell.
  • the stop can be arranged at the upper end of the linear guide and ensure that the guide element takes the receiving tray with it.
  • the guide element can hit the stop, so that in the event of a further movement, the receiving tray is then moved along with the guide element or the holding device.
  • the stop can hit the guide element when the holding device is located in the boundary plane.
  • the distance of the stop from the receiving shell or the length of the linear guide can be dimensioned such that the distance between the Receptacle and the holding device corresponds to the distance of the lowest storage level from the boundary level. If, for example, the second level is the boundary level, the linear guide can be so long that the distance between the holding device and the receiving tray corresponds to a storage level.
  • the receiving tray is suspended in a linearly movable manner on the holding device.
  • the receiving tray can be suspended from the holding device via the guide element.
  • the linear guide can be rigid struts, they can basically act like cables. Because if the receiving trays have not yet reached the lowest storage level, the receiving tray can move in the same direction as the holding device. If the holding device reaches the boundary level and the receiving tray reaches the lowest storage level, the holding device can be moved further down and then, for example, lift an ammunition body from the receiving tray.
  • the holding device it has turned out to be advantageous if it has two holding shells which are rotatably connected to one another at one end via a gear and at the other end via a rotary bearing.
  • the pivot bearing can be mounted in a guide element or the pivot bearing can be part of the guide element, so that the two holding shells can be rotated relative to the guide element.
  • the opposite side of the holding shells can be mounted in another guide element, so that the holding device is then arranged between the two guide elements and can be rotated relative to them.
  • a transfer position and a Gripping position is movable.
  • an ammunition body can be secured in the holding device and moved in the vertical direction together with the holding device.
  • the holding device In the gripping position, the holding device can be moved from above onto an ammunition body located on the receiving shell, so that the holding device encompasses the ammunition body at least in sections. If the holding device is then moved into the holding position, the ammunition body is secured in the holding device and can then be lifted off the receiving shell.
  • an ammunition body can be ejected from the holding device, in particular laterally, and then, for example, fed to a holding location of a magazine.

  • the magazine can have a plurality of storage locations arranged next to one another, with each storage location being assigned a holding device for holding an ammunition body, and a conveying device for conveying an ammunition body from one holding device to an adjacent holding device.
  • the ammunition bodies are stored or stored horizontally in the magazine.
  • This configuration means that the ammunition bodies are more easily accessible than, for example, when stored upright, and the ammunition bodies also generally have to be fed to the weapon in a horizontal position anyway, so that horizontal storage also simplifies the subsequent loading process of the weapon.
  • the magazine has a plurality of storage levels arranged one above the other, with each storage level comprising a plurality of storage locations.
  • This configuration leads to a dense ammunition body packing, so that the available standing space is used as well as possible.
  • the number of storage levels and the number of storage spaces per level can thus be adapted to the prevailing space conditions.
  • three storage levels, each with eight storage locations have proven to be advantageous for military vehicles. This would then correspond to a capacity of 24 ammunition bodies.
  • only one storage space can also be provided in each storage level.
  • each level has also proven to be advantageous with regard to different ammunition bodies. Because it is possible for each level to be assigned a specific ammunition body type, so that when an ammunition body or ammunition body type is selected, it can be taken from the corresponding level without the ammunition bodies of the other levels having to be moved.
  • a projectile lift In order to move the ammunition bodies of the different levels to a removal position, it has proven to be advantageous if a projectile lift is provided.
  • the projectile lift can transport the ammunition bodies to be stored to their corresponding storage level and then, when the ammunition bodies are removed, correspondingly transfer them back from the storage level to a removal position.

  • the ammunition bodies can only be removed from the magazine at a fixed point, and only at this point is appropriate space or a corresponding removal space required in the removal direction behind the magazine.
  • the magazine has two storage areas, with a projectile lift for conveying the ammunition bodies between the storage levels being arranged between the two storage areas.
  • This configuration reduces the distance the ammunition body travels from its storage location in the magazine to the projectile elevator.
  • the projectile lift can be arranged in the middle of the magazine, so that the two storage areas have the same size and accordingly the same number of storage spaces is present on both sides of the projectile lift.
  • the ammunition from the two storage areas can be fed to the ammunition lift independently of one another, which simplifies the selection of ammunition, for example.
  • the division of the magazine into two makes it possible to directly select twice the number of different ammunition bodies. If, for example, there are three storage levels, a different type of ammunition body can be present not only on each storage level, but also in each storage area of each storage level.

  • the ammunition passes through the storage areas, which lie between the projectile lift and the final storage area, before it arrives there.
  • the conveying device can move the ammunition body towards the projectile lift accordingly. Since all storage locations of the storage level or the storage area of the storage level between the storage location of the ammunition body to be removed and the projectile lift are passed through, the ammunition body that is closest to the projectile lift must always be removed first in each storage level.
  • At least one conveying device is located between the storage levels. This configuration enables the ammunition bodies to be conveyed with as few conveying devices as possible, which reduces the overall volume of the magazine.
