Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a shelf-type storage shelf device in which articles are loaded onto a movable storage unit such as a trolley, and the articles can be stored as they are or transferred to a transportation device and transported. Regarding.

Traditionally, to move mobile storage units from shelves, for example, a forklift truck is used as a transport vehicle, which circulates through the passages between the shelves, and its lifting forks are applied to each required shelf. Move the mobile storage unit.

Because of the lateral displaceability of the lifter, which is mounted on the forklift, pallets can be lifted off the shelf without using a forklift truck to swing across the row of shelves. It can be moved, which in turn allows for extremely narrow designs of shelf rows, perhaps a few centimeters wider than the width of the transport vehicle. The individual conversions are equipped with rails that are oblique and on which the storage units run, ensuring that the ends of the rails do not move too much and as a result fall of the mobile storage units from the shelving compartments. A stop device shall be provided at the end of the shelf compartment to prevent

Since the stop is formed in a hook manner at this end, flying of the rolling pallet with possible overshoots of the stop caused by movement relative to the stop is prevented. However, on the other hand, such hook-like stops can easily be seen to make the removal of the rolling pallet from the shelf converter substantially more difficult;
In particular, it is preferable to design the stopper so that it does not swing from the middle of the storage unit. All that can then be done is to release the rolling pallets from the stops and provide unlocking means to raise them onto these latter. For unlocking, the ends of the two shafts are arranged on the rails of the shelf in the area of the stopper and arranged in a plane parallel to the rails so as to be free to rotate on the ordinary shafts. It has already been proposed to use two rollers receiving side slot-like guides that allow parallel movement of the shaft with simultaneous lifting of the rollers.

However, in this solution, the platform is mounted on the transport vehicle and connected to the transport vehicle of the parentheses. The shaft cannot be operated without a hydraulically driven plunger intended for translation of the shaft within the guide. An improved device of this type, which is slightly simpler in construction, comprises an unlocking means for releasing the rolling storage means from the stopper and lifting it onto the safety hook.

The unlocking means is mounted on the end of the mounting device which rotates towards the shelf closure and is mounted so as to be freely rotatable on a shaft that is perpendicular to the direction of movement of the lifting device. The end has a roller whose shaft projects beyond the roller and forms a guide bolt cooperating with a guideway in the area of the shelf opening. Although this system has given very good results, it also suffers from the disadvantage of having a large number of moving parts that require maintenance and lack proper operation. The object of the invention is to provide an improved storage shelving device of the type mentioned above, which no longer includes the drawbacks mentioned above and without adding any moving parts either on the shelves or on the lifting device. The mobile storage unit can be removed from the shelf without any problems.

In order to achieve such an object, the storage shelf device of the present invention has a downward slope toward the take-out end side for loading and unloading a movable storage unit that is loaded with articles to be stored or transported but is not transported with the articles. Each shelf is provided with a track wave member having an inclined running surface, which is inserted between the storage shelf capable of carrying and accommodating the movable storage unit and the track wave member on the take-out end side of the storage shelf. a lifting device that rises when the mobile storage unit is moved and lifts the mobile storage unit to carry out or carry in the mobile storage unit, but descends and leaves the mobile storage unit after the transfer is completed; a stopper means for preventing the movable storage unit from falling on the removal end side of the member; a movable storage unit provided with a cross member that engages with the stopper means at the front and rear ends outside the axle; and further the track weave member. a convex protrusion that raises the cross member at the rear of the movable storage unit to a higher position than the stopper means at the ejection end of the movable storage unit; The distance between the storage unit and the rear cross member of the mobile storage unit is at least equal to or less than the distance between the rear cross member of the mobile storage unit and the vehicle marrow.

Next, embodiments of the present invention will be described below with reference to the drawings.

The basic structure of storage shelves is already known.

Therefore, only those parts relevant to the present invention will be described in detail below. A storage shelf in the form of a rectangular stand is shown in FIG.

This storage shelf accommodates storage and transport units (referred to herein as mobile storage units) 3 on pallets 2 loaded with articles 1 . The stand has a number of vertical members, which are connected to each other through horizontally extending traverse members 4. The longitudinally elongated trackwave members 5, 5' rest on the traverse member 4. The track wave members 5, 5' are preferably constructed as bars and have running surfaces that are slightly inclined downward in the direction of the arrow P with respect to the horizontal, ie towards the take-out end of the shelf. A stopper mechanism 10 is provided on the outer surface of the end of the trackwave member 5, and this stopper mechanism 101 prevents the movable storage unit 3 from passing through the end of the trackwave member 5, 5'. A mobile transport vehicle 8 (FIG. 1) is mounted in a known manner on the front side of the shelf.

This vehicle 8 is equipped with a transport mechanism 9 for loading and unloading the shelves. Referring to FIG. 2, part of the trackway 5, ie part of the end leading to the take-out end of the shelf, is shown in detail.

Within each shelf there are two trackway members 5, 5' within each shelf mounted on a horizontally disposed traverse member 4, which members 4 form a shelf structure as shown in FIG. forms part of it. In the area at the end of the trackway 5, usually 1
A stopper mechanism 10, designated by 0 and fixed to the outer surface of each trackway 5, 5', is provided. This stopper mechanism 10 includes an upwardly protruding stopper member 11.
, which protrude above the top rail surface of the trackway member 5. The stopper section 11 is
It is fixed to a horizontally extending carrier member 12 which extends substantially parallel to the track members 5, 5'. The carrier element 12 is received by a sleeve 13 which is rigidly fixed to the trackway elements 5, 5' and cushions the blows caused by the movable storage unit 3 pressing against the stop element 11, which is part of the stop mechanism 10. In order to do this, means are provided for causing a cushioning movement of the carrier 12 with respect to the sleeve 13. As is clear from FIG. 2, there is a certain distance between the ends of the trackway members 5, 5' and the stopper mechanism 10, the purpose of which will be explained later.

In the end area of the trackway part 5, i.e. between the stopper mechanism 10 and the ends of the parts 5, 5', there is a knob-like or convex projection 14 on the top or running surface of the trackway part 5. The purpose is as described below. Referring to Figures 3-7, there is shown a schematic view of a shelf and a portion of the trackway member 5 at the take-out end of the lifting device 9 located at the front of the shelf.

On the trackway 5 there are a number of mobile units 3 loaded with goods 1. In the present example, each unit 3 consists of a load-receiving platform, a so-called truck 3', with four wheels or rollers 5 arranged at the four corner parts of the platform 3'. At the front part 3 and at the rear of the unit, a downwardly extending cross member 16 is provided and adapted to engage the stop member 11. The rotation axis of the roller 15 is located inside the cross section 16, and is located behind the roller 15 on the front end side. A cross member 16 is present, and a roller 15 is arranged behind the cross member 16 on the rear end side. The storage units 3 loaded in this way can be reliably placed on the trackways 5, 5' even if they are oriented in the opposite direction. The lifting device 9 consists of a schematically drawn frame structure 17 that can be moved toward and retracted from the shelf.

For reasons of simplicity, only the most essential parts of the lifting device 9, namely the endless chain or belt 18, are shown in the figures. As shown in FIG. 3, the transport vehicle 8, which has just docked on the shelf and the movable part 9 with its belt 18 of the lifting device 9, moves towards the shelf and the mobile storage to be transferred from the shelf. It is located below the front of the unit 3 and between the trackways 5 and 5'.

The storage unit 3 has its front cross member 16 in contact with the stopper member 11, and the shelves or trackways 5, 5'
It is designed to prevent it from falling. Then, as can be seen in FIG. 4, the entire raising device 9 is raised somewhat and the endless belt 18 is switched on and rotated in the direction (counterclockwise direction) for pulling out the mobile storage unit 3. . As a result, the cross section 16 of the unit 3, and ultimately the entire unit 3, is raised and can pass over the stopper member 11. The rear roller 5 is the trackway 5,5
', while the belt 18 is further driven,
Unit 3 then begins to be pulled out from the shelf. It can clearly be seen that the rear cross member 16 approaches the stop member 11 and prevents the unit 3 from being pulled out further. To overcome this, knobs 14 are provided at the ends of the trackways 5, 5'. Just before the rear cross member 16 reaches the stopper member 11, the rear roller 1
5 reaches the protrusion 14 and rides on it, pushing up the rear part of the unit 3. Correspondingly, the rear cross member 16 moves upward. This state is shown in FIG. The rear roller 5 reaches the top of the protrusion 14,
As a result, the rear cross member 16
Overcome 1. The unit 3 is now pulled further forward so that the rear cross member 16 also rests on the endless belt 18. The second storage unit 3 naturally moves forward until its front cross member 16 abuts against the stop 1 due to the downwardly inclined trackways 5, 5' towards the take-out end of the shelf, i.e. towards the transport mechanism. Start moving forward.

If it is desired to raise this second unit 3 as well, the lifting device 9 is lowered and raised again to raise the front end portion of the second unit 3, and the belt 18 is then driven. The whole process is repeated. As soon as the desired unit or units 3 are loaded onto the lifting device 9 of the transport vehicle, the movable parts including the belt 18 are retracted (FIG. 7) and the units 3 are transported to any desired destination. can also be transported.

It is important that the projection 14 raises the running surface of the trackway 5, 5' at least slightly higher than the effective height of the stop member 11. Furthermore, the distance between the stop member 11 and the top of the projection 14 must be equal to or less than the distance between the cross member 16 and the axis of rotation of the roller 5. In practice, the distance between the top of the protrusion 14 and the stopper member 11 is set such that the distance between the top of the protrusion 14 and the stopper member 11
It should be slightly smaller than the distance between 6 and the axis of roller 5. With such a construction, a very simple, reliable and inexpensive solution is provided for transferring loaded storage units from shelves to transport vehicles.

Furthermore, no moving parts are required on the shelf or in the lifting device, which also requires additional care or maintenance and involves additional high costs.
