Definitions

  • the invention relates to a container for rod-shaped workpieces, in particular those whose length is a multiple of their cross-sectional dimension or their diameter, the length dimension of which can be infinitely adapted to different workpiece lengths, in particular in which unhindered access to the workpieces stored in it is possible from one or both sides is.
  • the stepless adjustment (setting) to different workpiece lengths is intended to ensure that the workpieces are precisely positioned in the container and remain in their position even when shaken, for example during transport, and that the container in the set state only ever requires that in the longitudinal direction of the workpiece Has dimensions so that no storage space is lost during storage.
  • Containers are known which are used specifically for the transport and storage of a wide variety of workpieces. Small parts as well as cylindrical parts and rod-shaped workpieces, the length of which is several times their cross-sectional dimension, are stored and transported therein.
  • the so-called lattice box pallets are known. These are containers with standard dimensions, which are standardized according to DIN 15155.
  • a transport container is provided for the "workpiece magazine for tubular and rod-shaped workpieces", which is patented by German Patent No. 3420014. It would be an advantage if a container with standard dimensions according to DIN 15155 or similar could be used for this, in order to standardize the operating equipment within a company. Since the workpieces have to be guided on the boundary walls of the transport container during the loading and unloading process of the workpiece magazine, a container with standard dimensions can only be used if the workpiece lengths match the internal dimensions of the container. This will rarely happen. In addition, workpieces are often stored by a user that have the same lengths per container filling, but are otherwise of different lengths. A container with standard dimensions can therefore not be used as a transport container (patent 3420014) that can be inserted into the workpiece magazine for different workpiece lengths, since its dimensions cannot be changed.
  • the invention has for its object to achieve a continuous adjustment of the container dimensions to the different workpiece lengths.
  • boundary walls on the container that prevent the workpieces from slipping out in the longitudinal direction of the workpiece -
  • One or both of the boundary walls can be removed without using a tool, on the one hand to ensure unhindered access during loading and unloading and on the other hand to lower the carrying straps of the workpiece magazine unhindered when containers are used in the workpiece magazine (German Patent 3420014) can: -
  • the removable side walls are at a substantial distance from the frame parts so that the carrying straps of the workpiece magazine have space between the side walls and the frame parts: -
  • a non-adjustable container part for a workpiece length is provided for use as a transport container in the workpiece magazine.
  • the removable side panels are attached to the frame part.
  • This version is used for the workpiece magazine if only workpieces with a length are to be magazineed; -
  • the adjustment (adjustment) of the container is carried out via a drive system that is plugged onto the two threaded spindles in the case of two articulated rod systems.
  • a hand crank / wheel By turning a hand crank / wheel, both threaded spindles are adjusted simultaneously; - Electric, pneumatic or hydraulically driven motors are provided instead of the hand crank / wheel, with which a quick adjustment of the threaded spindles is achieved; -
  • two or more containers can be connected to one another by means of connecting elements, for example screws.
  • the container is connected to a non-adjustable container part by means of connecting elements.
  • This combination is used for the storage of longer workpieces than the container can normally accommodate, if the shortest of the workpieces to be stored does not fall short of the dimension of the non-adjustable frame part, -
  • the two frame parts are connected to one another by a pair of articulated rods, the articulated rods of which are in turn rotatably connected to one another at their crossing point.
  • the advantages that are achieved with the invention are, in particular, that the space utilization of the container is always optimal, even if the workpiece lengths of different container-workpiece lots (same workpiece lengths per container filling) are different.
  • the workpieces are arranged in a stack in the container and, if two boundary walls are provided, cannot slip in the event of vibrations (transport). This is a convenient, rational loading and Unloading possible, especially or primarily in connection with removable side walls (without tools), which gives good access to the workpiece stack.
  • the container If the container is correctly adjusted to the workpiece length, its dimensions are always only as large as is necessary according to the workpiece length. This means that no storage space is wasted when storing the containers, which is particularly true of empty containers that can be made as small as possible for storage.
  • containers By connecting two or more containers to one another, even with non-adjustable container parts, containers can always be built for the most varied workpiece length ranges using the same construction ribs (modules). This achieves a high degree of flexibility for the most varied of requirements with regard to the storage of workpieces of different lengths.
  • the removable side walls have the advantage that the carrying straps of the workpiece magazine no longer have to be installed and removed when changing the container and must remain in the container, which means one pair of belts per container, but after the boundary walls have been removed when the container has been inserted, can be lowered as far as that the container can be brought in or out over the carrying straps.
  • FIG. 1 In the side view of a container according to the invention, one of two articulated rod systems (3,3 '), which connect the two frame parts (1.2) with one another, is shown in FIG. 1, and the side view of two frame parts (1,2) and two boundary walls ( 26.30).
  • Fig. 4 a section along the line II in Fig.1, the U-shaped frame part (1), which has the same dimensions as the frame part (2), is shown in the side view.
  • the arrangement of the two link rod systems (3.3 ') can also be seen here.
  • the articulated rods (4,4 ', 4 ⁇ , 5,5', 5 ⁇ ) are at one end at the attachment points (14,15,16) each with a threaded nut (9,10,11) with the other end the attachment points (12,13,17,18) of the frame parts (1,2), each rotatable about the attachment points (12 to 18).
  • the longitudinal axes (6,6 ⁇ or 7,7 ⁇ ) of the joint rods (4,4 ⁇ or 5,5 ⁇ ) run perpendicular to the angle ( ⁇ or ⁇ ), which is greater than zero degrees the imaginary lines (19, 20) standing along the longitudinal axis (8) of the spindle (21), and parallel to one another.
  • the longitudinal axis (6 'or 7') of the link rod (4 'or 5') runs in mirror image to the longitudinal axes (6.6 '' or 7.7 '') of the other link rods (4.4 '' or. 5.5 ''), based on the imaginary lines (19; 20).
  • the mirror-image arrangement of the articulated rods (4 ', 4'',5', 5 '') to each other causes that the frame parts (1,2) and the threaded spindle (21) do not move in the direction of the arrow (b, c, d) against each other can.
  • the two articulated rods (4,5) prevent the two frame parts (1,2) from pivoting around the fastening points (13, 18). If, in deviation from the arrangement shown on the frame parts (1, 2), for example, 3 attachment points are provided for 3 articulated rods each, the same effect and function is achieved.
  • the threads of the threaded nuts (9, 11), on which the mutually parallel joint rods (4.4 '', 5.5 '') are fastened have the same thread pitch and Aisle direction, for example left-handed.
  • the threaded nut (10), on which the non-parallel joint rod (5 ', 6') is attached also has the same thread pitch, but a different direction, for example clockwise. If the threaded spindle (21) is rotated, for example with the help of the crank (27) which is connected to it, the threaded nuts, the threads of which have the same direction of travel (9, 11), move in one direction by the same length and Threaded nut (10) whose thread is in the opposite direction by the same amount of length in the opposite direction.
  • the distances (e, f) which the frame parts (1, 2) have from one another are shortened or lengthened, depending on the direction of rotation of the threaded spindle (21).
  • the workpieces (34) rest on the webs (28, 29) of the frame parts (1, 2) on or on the inner surfaces of their vertical side legs.
  • the spindles (21,21 ') (Fig.1 and Fig.4) of the two link rod systems (3,3') the distances (e, f) with which the frame parts (1,2) can be separated from each other are changed and continuously adapted to different workpiece lengths.
  • the two boundary walls (26, 30) fix the workpieces (34) in their position in the container, ie they prevent them from slipping out sideways (in the longitudinal direction of the workpiece).
  • the boundary wall (26) is firmly connected to the frame part wall (25) of the frame part (2).
  • a removable boundary wall (30) is provided on the frame part (1). With it 4 hook-shaped fastening elements (31) are firmly connected, which engage with their hooks in recesses (32) of the frame part wall (33) of the frame part (1) (saFig. 4). If the boundary wall (30) is attached, for example A lifting of the boundary wall (30) upwards is prevented by a pivotable locking device, not shown.
  • the boundary wall (30) can only be raised when the locking device has been released, so that the fastening elements (31) disengage from the cutouts (32) and the boundary wall (30) can be removed. The process happens without the use of a tool.
  • FIG.2 Another version of the link rod system is shown in Fig.2.
  • the threaded spindle (23) is mounted in the bearings (25 ', 26') of one of the frame parts (24) - in contrast to the threaded spindle (21,21 ') in Fig.1, which only in the threaded nuts (9,10, 11) is held.
  • the articulated rods (35,35 ', 35' ') are arranged in the same way as in the embodiment according to Fig.1, but only half the number.
  • the two boundary walls (36, 37) are removable. Your fasteners (38) firmly connected to them are so long that the distances "a" of the boundary walls (36, 37) from the frame parts (22, 24) are so large that the risers (40, 40 ') have one
  • the workpiece magazine patented by the German patent 3420014 fits in unhindered in terms of its width.
  • the risers (40.40 ') are shown in section.
  • the workpiece magazine (43) is shown schematically in Fig.3. In the magazine (43) there is the transport container (44) which receives the workpieces (47).
  • the transport container (44) is removed after it has been filled in the workpiece magazine (43), or it is inserted into the workpiece magazine (43) in the filled state, so that the workpieces can be removed (see patent specification 3420014).
  • the two risers (40, 40 '), in which the workpieces (47) lie during loading and unloading, are at one end to the Drums (45.45 ') attached, which are motor-driven and wind up or unwind the carrying straps (40.40'), with their other end at fixed points (46.46 ') of the workpiece magazine (43). If a workpiece filling process is finished, the workpieces are initially in the carrying straps (40, 40 ').
  • the carrying straps (40.40 ') at the fixed points (46.46') must be loosened and wound up by winding them on when the four side walls are firmly connected to one another Drums (45, 45 ') are pulled out of the transport container (44) or under the workpieces (47) filled with them.
  • the carrying straps (40, 40 ') must first be pulled under the workpieces (47) and attached to the Fixed points (46.46 ') are attached.
  • the pulling out or pulling through of the carrying straps (40, 40 ') can be omitted.
  • the risers (40.40 ') must be released from their fixed point (46.46'). If, for example, the container in the workpiece magazine (43) has been filled, the boundary walls (36, 37) can be removed on both sides. Since the risers (40, 40 ') lie outside the frame parts (22, 24, Fig. 2), they can now be lowered unhindered until they have assumed the position shown in dash-dotted lines in Fig. 3.
  • the risers (40.40 ') are on Frame of the workpiece magazine (43) attached, for example, by hanging in the devices provided (48,48 ', 49,49'). Now the container (44) can be pulled out after it has been lifted slightly, for example with the help of a mobile transport device (forklift truck) via the carrying straps (40, 40 ') remaining in the workpiece magazine (43).
  • the boundary walls (36, 37) can be reattached to the container beforehand.
  • the threaded spindles (21,21 ') are rotated about their longitudinal axis (8, Fig.1), for example with the help the cranks (27,27 ', Fig.4).
  • the other spindle is adjusted.
  • the canting that occurs which results from the unequal spacing of the resulting during the adjustment process on the two link rod systems (3,3 ') attached frame part ends result, balanced.
  • a drive system (62) that makes it possible to adjust both threaded spindles (21, 21 ') at the same time is shown in Fig.5.
  • the threaded spindles are adjusted via the two toothed belt wheels (66,67). These are mounted in the housing (64) and on one side each with a coupling half (63,63 '), in the example of Figure 5 formed as an inner square. These coupling halves (63, 63 ') fit in a form-fitting manner on the coupling halves (61, 21') provided on the threaded spindles (21, 21 '), formed as a square in the example of Figure 5.
  • the two toothed belt wheels (66, 67) are positively connected to one another by a toothed belt (68).
  • the toothed belt wheel (66) is firmly connected to the crank (69). Since the distance between the toothed belt wheels (66,67) from each other and the distance between the threaded spindles (21,21 ') from each other is the same, the drive system (62) with its coupling halves (63,63') on the matching coupling halves (61,61 ') Of the threaded spindles (21,21') are plugged on, so that a positive and non-positive connection is made between them and the toothed belt wheels (66,67). If the crank (69) is rotated, both threaded spindles (21, 21 ') are adjusted simultaneously. Instead of the crank (69), a motor can also be provided as the drive.
  • a container with a larger setting range is required for longer workpieces (72)
  • These are, for example, containers corresponding to the design in FIG. 1, but with two removable boundary walls.
  • the screws (71) are guided, for example, through the cutouts (32) in the frame part walls (25, 33) of the frame parts (1,2), after the boundary walls (26,30) have been removed. In this way, several containers can also be connected to one another.
  • FIG.7 Another container design for longer workpieces (76) is shown in Fig.7.
  • the adjustable container according to FIG. 1 is connected to a non-adjustable container part (75) by means of screws (77).
  • several adjustable containers with several non-adjustable container parts (75) can be connected to one another.
  • Fig. 8 shows a variant in which the frame parts (80, 81) are connected to one another by at least one pair of articulated rods (82) and the individual articulated rods (83, 84) are in turn connected to one another at their crossing point with the aid of a bolt (85) .
  • the articulated rods (83, 84) are rotatably fastened at one end to the frame parts (80, 81) in the articulation points (86, 87).
  • the other end of an articulated rod (84) is rotatably attached to the threaded nut (89) at the articulation point (88), the other end of the articulated rod (83) at the articulation point (90) of the slide bush (91).
  • the threaded nut (89) is seated on the threaded spindle (92), which is rotatably mounted in the bearing points (93, 94) which are firmly connected to the frame part (81).
  • the sliding bush (91) sits on the axis (95), which is firmly connected to the frame part (80), and can be displaced on it in the longitudinal direction.
  • the sliding bush (91) slides up or down on the axis (95) in the longitudinal direction of the axis.
  • the articulation point (90) can also be guided in another manner in the frame part (80), for example in slots in the frame part (not shown).
  • two or more pairs of joint rods can be arranged one above the other, all of which are adjusted via one and the same threaded spindle.
