Transit storage shelving systems are known in which the goods to be stored are placed on shelves with rails on top of the transportable storage and transport units, in which case a transport vehicle with a device for emptying the shelves is arranged on the exit side of the shelf (e.g. Swiss Patent Publication 557,796). Such equipment has already successfully used simple rail wagons that roll freely on a sloping section to transport goods. In this case, the inclination must be dimensioned in such a way as to ensure that the wagons self-rolling, whether rir 'r * 1 swanst i. Or lightly loaded or completely unladen.

However, on the other hand, such a large slope causes the carriages to accelerate to too high a speed, so that the carriages have to be braked repeatedly. For this purpose, braking devices are provided on the carriageway. In this case, an essential condition for such a braking device is that the braking, i.e. the reduction in speed produced by the braking device, is as independent as possible from the loading beam and thus from the weight of the wagons.

A wide variety of braking devices have been proposed which better or worse meet the requirements imposed on them (for example, Swiss Patents 573 832, 557 252, 561 619, 568 874}.

In this case, however, the disadvantage is that a large number of such braking devices are required, which leads to considerable costs in large through-stock storage systems.

The object of the present invention is to provide a solution in which the use of braking devices can be dispensed with. This is achieved by providing a low-pass, self-rolling, but low-braking carriageway for wheeled carriages, so that when the carriages are removed from the equipment, each carriage is given a movement impulse on the carriageway.

In this case, the movement impulses are sufficient to move the wheelchairs by a few carriage lengths, whereby the rolling carriage stops slowly again due to the rolling resistance without the need for any additional braking devices. It is important that the inclination is so small that there can be no self-rolling of loaded or empty wagons.

The very sharpness of the track also causes the rises that result from the deflection of the track between the two supports of the track caused by the transport load. In all cases, however, the rolling resistance of the wheels of the wheel carriages remains greater than the acceleration caused by the slope of the path of the carriageway, whereby the wagon set in motion by the motion rolls slowly and comes to a stop.

The through-storage storage system according to the invention is characterized in that the track spends such a small amount that the acceleration generated in the wheel carriages r> Ltori is less than that caused by the rolling resistance.

3 62803 It may be arranged a tension spring which is secured at one end to the push rod and the other end of the shelf outlet side pääähän hand, to maintain the push rod towards the rest of the shelf space opposite the offset position. At the same time, the spring acts as an energy accumulator for the motion impulse that is given to the carriages.

The grippers are pivotally connected to the push rod and are pivotable from the impact position projecting onto the carriageway to the rest position outside the carriageway.

In a simple embodiment, each gripper is made as an eccentrically mounted two-arm lever with a second, longer lever arm resting against the push rod and a second, shorter lever arm extending into the path of the carriage.

A requirement to be placed on such grippers is that the rolling carriage may pass over them when the push rod is stationary. When the grippers can be pivoted from their operating position, in which they protrude into the path of movement of the carriage, to the rest position, where they pivot inside the push rod, this requirement is met, thus also ensuring that the grippers return to their operating position by themselves. This is done by gravity by forming the grippers as double-arm, eccentrically pivotally mounted levers.

Tests performed by the applicant with such equipment have encountered the following problem: Although all the wagons in the shelf compartment have been affected by a theoretically similar motion impulse, in practice there are significant differences in the speed of the different wagons after the impulse was pushed by the impulse. On the one hand, this may be due to the different weight of the different wagons, and on the other hand, it may also be due to the fact that the wearability of the rail track is not uniform along their entire length. In any case, it is desirable to equalize the speed of the rolling carriages relative to each other and without expensive adjustment devices.

According to the embodiment of line aovc I of the invention, the speed smoothing can be carried out in the simplest possible way without using additional energy.

4 62803 In this application, the grippers are bearing levers pivoting at one end of the push rod, which are acted upon by low retraction and high damping resilient retractors which tend to push the levers into an impact position projecting from the carriage path. The free end of the levers has a pushing surface located at an angle of 90 ° or slightly greater than the lever.

The invention will be described in more detail below with reference to the accompanying drawings, which show more or less schematically exemplary embodiments of the invention and in which Fig. 1 shows a part of a transit storage shelving a schematic fit of the impeller, Fig. 5 shows a side view of the impeller, Fig. 6 shows a cross-section of the impeller of Fig. 5, and Figs. 7-11 show a partially sectioned push rod with otherwise formed grippers in different positions.

The transit storage shelving system has a storage rack intended for receiving storage and transport units, i.e. wagons 2, loaded with goods 1. The rack consists essentially of a plurality of vertical beams 3 connected to horizontally extending transverse beams H. The horizontal bars 4 on the leaning is attached to the longitudinal beams 5 »which support the rails 6 extending from the horizontal in the direction of the arrow P, i.e., the so-formed shelf compartment in the direction of the outlet end of the sloping bit. At the end of the rails 6, securing devices 28 are mounted, which prevent the storage and transport units 2 from accidentally passing over the rail of the rails.

The inclination of the rails 6 is chosen so that the storage and transport units cannot in any case roll on their own. The rolling motion of the storage and transport units in rolling motion is moderately decelerated because the acceleration caused by the low wearability of the rails is less than the deceleration caused by the rolling resistance of the wheels. Under the load of the loaded storage and transport units, the rails 6 are subjected to deformation by bending slightly between two successive transverse beams 4, so that the rolling of the wheels at acceleration 5 62 80 3 initially accelerates slightly and then decelerates again with the rising part. : it is sufficient for the overall traceability of the rails 6 to be dimensioned so that the rolling wheels do not come to a complete stop due to said rail deformation.

At the front or exit end of the shelf, a transport vehicle S equipped with a receiving device 9 must be driven.

A motion impulse transmitter is arranged between the rails 6 forming the track, which acts on the storage and transport units 2 when one of the storage transport units is removed by means of the transport vehicle 8.

The detailed structure of the motion impulse transmitter can be seen in Figures 2 to 6. The motion impulse transmitter is formed as a push rod 10 and is arranged between the rails 6. As can be seen from Fig. 6, the push rod has a U-shaped upper part 11 and a double guide-shaped lower part 12 with a sliding surface 13. Mounted on the lengths of the rails 6 are bearing brackets 14 on each of the transverse beams 7. each receiving a roller 15 against which the push rod is pushed. sliding surface 13 leaning. In this way, the push rod is movably mounted on the rollers 15 along the length of the rails 6, whereby the double guide 12 has flanges 14 '. The transfer can only take place against the action of the spring 16, which tends to keep the push rod 10 in the end position. To move the push rod 10, a drive rod 17 is provided, which on the one hand communicates at point 13 with the push rod and on the other hand at 19 with a pivot arm 20 pivotally mounted at 21. The arm 22 connects the pivot arm 20 to the trigger 23. This shelf is adapted to store a front-off downside to such a manner that the receiving device 9 is set in place the shutter 23 is rotated in the direction of the arrow, whereby the operation rod 17 moves through the arm 22 and the pivot 20 of the lever arm. As a result, the push rod 10 also slides on the rollers 1.5 against the action of the spring .16, whereby said spring 16 is tensioned.

"The drawbar 10 is provided with stops, i.e. grippers 24, mounted at regular intervals on the push rod rivet 6 62803 rotating about the shafts 25 in the U-shaped rod portion 11. The grippers usually assume the position shown on the right side of Fig. 5 where they will rest on the U-shaped top 11 'against the bottom, while the surface 24 "runs vertically and acts as a abutment surface for the cross member 26 of the storage and transport unit 2. It is clear from Figure 5 that the passage over the grippers can only take place from left to right, but not in the opposite direction. turn clockwise to the position shown on the left side of Figure 5. In this position, the grippers 24. no abut against the stop bolts 27.

Figure 4 shows above all the general arrangement of the push rod 10 provided with grippers 24 with respect to the transverse beams 4 and the storage and transport units 2 when the spring 16 is untensioned. When the receiving device 9 is in place to remove the foremost storage and transport unit, the trigger 23 turns counterclockwise and the drive rod 17 moves from right to left, whereby the spring 16 is tensioned and the push rod 10 also comes to move to the left. This slides the stocks under the transport units 2 and engages in its end position with the grippers 24 again behind the cross beams 26 on it. After the receiving device 9 is removed from its position, the spring 16 returns to its untensioned state and then moves the push rod 10, as a result of which the grippers 24 impart a movement impulse to the crossbars 26. This light impulse causes the storage and transport units 2 to roll from left to right. one length. The frontmost storage and transport unit enters the discharge station and the repositioned receiving device 9 can receive and transport it away. If the impulse given once is not enough to move the storage and transport units 2, then a second or third impulse can be given by the receiving device 9 or by manual control,

A modified embodiment of the motion impulse transmitter in many respects is shown in Figures 2, 3 and 7-11.

Figures 2 and 3 show the shelf compartment removal side. The rails 6 continue towards the feed side, so that the total length of the shelf compartment can be 20 m.

At the end of the rail track thus formed, abutments 28 are arranged, which 62803 7 prevent the carriages from passing over the end of the shelf compartment.

The rails 6 between which is mounted displaceably in the direction of the arrow P the push rod 10. The bearing arrangement may be similar to that illustrated in Figure 6. It is acted upon by a spring 37 which tends to push the push rod towards the discharge side. Fig. 2 schematically shows an removal or receiving device 9, which provides for the removal of the outermost carriage from the shelf compartment. When this receiving device 9 is driven in front of the shelf compartment, it presses the stop 39 against the end face 40 of the push rod 10 and moves the push rod against the action of the spring 37 towards the feed end of the shelf compartment. In Fig. 3, the receiving device 9 is no longer in front of the shelf compartment, so that the front surface 40 is no longer affected by any force. The push rod 10 moves to the influence of the spring 37 in the direction of arrow Q.

The push rod 10 is provided with a plurality of grippers 41, the structure of which can be seen in Figures 7-11. In the embodiment example shown, a U-profile is used as the push-button 10, which is open upwards, whereby the grippers 41 are attached to the inside of the U. The latter are single-arm levers 42 mounted at one end via a bolt 43 on a push rod 10. The other end of the lever 42 has a push surface 44 at an angle of about 99 to 100 ° to the lever 42. In addition, a stop 45 is attached to the push rod 10, against which an angle-bent extension 46 attached to the free end of the push surface 44 rests. The stop 45 restricts the upward movement of the gripper 4l. The restriction of downward movement is provided by the extension 46 resting against the lower part 10 'of the U-shaped push rod 10.

Below the lever 42, a return member 47 is arranged. protrudes above the upper surface of the push rod 1Q. The fully inverted position of the gripper M1 is shown in Fig. 9, from which it is also clear how the return member 4γ has elastically deformed.

Essentially, the material from which the return member 47 is made has a low specific frequency and a high specific attenuation. Tests performed by the applicant 8 62803 have shown that butyl rubber meets these requirements very well. Of course, other substances can also be used.

The operation of the modified embodiment is as follows:

It is required that schematically illustrated in Figures 1 and 2, the discharge or receiving device 9 has just been removed position, wherein the push-rod 10 moves the spring 37, the influence of the arrow shown in Figure 3 of the shelf in the direction Q toward the outlet end. In this case, each carriage 2 on the rails 6 o] receives an impulse via the grippers 4l, so that all the carriages 2 begin to move towards the outlet end of the shelf. Due to their continuity, the carriages 2 continue to move after the push rod 10 has completed its stroke and exceed a smaller or larger number of grippers 4l. These are pushed downwards by the carriage rolling on them, but turn upwards again as soon as the carriage passes them.

Figures 7 to 11 show the position of the gripper at different stages of its movement when the pile 2 rolls over it and then presses downwards under the action of the carriage cross beam 51. In this case, the carriage 2 moves in the direction of arrow shown in the cross direction of the beam.

Step 1 (Figure 7).

The gripper 41 is in its unfolded operating position and remains pressed against the stop 45 by the return member 47. The cross member 51 of the carriage 2 approaches.

Step 2 (Figure 8)

The cross beam 51 has reached the gripper 41 and starts Daina against this downward action of the return member 47.

Step 3 (Figure 9) «

The gripper 41 is fully depressed by the crossbeam 51 and the return member 47 is deformed from the maximum.

Step 4 (Figure 10I

The cross beam 51 of the carriage 2 starts to exit and the gripper 4l rises upwards again under the action of the return member 47.

9

Step 5 (Figure 11) 6 2 80 3

The cross beam 51 has just left the area of action of the gripper 4l and the gripper will be pressed again upwards by the action of the return member 47.

Two different situations must now be noted: 1. The cross beam 51 of the carriage 2 passes over the gripper 4l at a relatively high speed. As the crossbar passes over the lever 42 and the subsequent deformation of the return member 47, the energy of the carriage decreases, resulting in a slower travel speed, (steps 1-5). Due to the low specific frequency and high specific damping of the material used in the return member 47, the gripper 4l returns relatively slowly again, whereby the carriage has already passed the entire area of the gripper when it has returned to its unfolded operating position (step 5). This means that step 4 is over. This step is repeated for each gripper 8 over which the carriage passes, therefore until it stops by itself or by a response 28.

2. The cross beam 51 of the carriage 2 rolls over the gripper 4l at a relatively low speed. Due to the passage of the lever 42 and the subsequent deformation of the return member 47, the energy of the carriage is again reduced (steps 1 to 3). However, part of this energy acting on the return member 47 will immediately act on the carriage again, whereby the gripper 41 moving back to its operating position slides on its pushing surface 44 along the rear edge of the carriage and the carriage speed increases again (step 4). Of course, not all the energy removed is recovered, so the slow trolley stops after it has passed over a few grippers 4l. With the next move of the push rod 1Q, the carriage is then moved again and the explained steps are therefore repeated until the slow carriage has reached the end of the shelf compartment.

As described above, the speed of the carriages is adjusted without the need for any expensive accessories.
