Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for rotating about a vertical axis and to an apparatus for carrying out the method.

A "load unit" in the present invention means a complete load or load-bearing platform, but in the following in this application only reference will be made to the material handling pallet, which is its main content.

In many warehouses that store cargo handling equipment in the form of cargo handling pallets loaded with cargo, the two lowest pallet racks are usually used as collection points by collection workers. However, the remaining positions of the pallet rack function as storage positions for cargo. Pallets are usually placed with their strip sides facing the outer aisles to save space. In terms of work equipment, low-lift pickup trucks are utilized to retrieve orders, while reach trucks are used to insert pallets, retrieve empty pallets, and lower storage pallets to annual revenue locations.

When a collection worker picks up the items on a pallet and removes half of the items, this creates an inconvenience, such as having to occupy a very inconvenient working position when picking up the remaining items over a long distance in the aisle. . These items, which may be relatively heavy, pose a significant risk of injury to collection personnel, and therefore the collection methods described above require frequent leave of absence and personal reassignment.

A possible solution to the above-mentioned problem was to arrange the pallet so that the long side of the pallet rotates outward, but this is less efficient than when the long side of the pallet is turned outward. It is not very economical as it requires more floor space to store large quantities of pallets.

Another solution is to remove half of the empty pallet with a reach truck and lower the pallet onto the floor below.
A method was considered in which the pallet was rotated to the other side, the truck was rotated, and the pallet was picked up and returned again. However, this method is very time consuming and requires blocking the road, making it impossible for other trucks to pass. This means that even though the pallet is suitable for being rotated, it is not desirable to carry out this method as it involves an inconvenient process and may pose a hazard to the operator during the picking process.

Accordingly, the main object of the present invention is to provide a method for carrying out the above-mentioned steps in a manner that allows the handling equipment to be rotated simply, quickly and effectively. Another object of the invention is to provide a device for implementing the method described above.

The above-mentioned objects are achieved by the present invention, which mainly consists of a device transport device in which the material handling device is removed from its storage position by a lifting member and moved in a rotational position 1 located on the lifting member, the device being rotatable about an approximately vertical axis. The cargo handling device is placed on the container and rotated to a desired position, and then the cargo handling device is appropriately returned to its storage position. Furthermore, an apparatus for carrying out the above-mentioned method is characterized in that the cargo handling device, which can be rotated approximately on a vertical axis, is placed on a load lifting device, which is a truck, in particular a so-called reach truck. It is something.

In the following, the invention will be explained in conjunction with an embodiment of the invention in the accompanying drawing, which shows a perspective view of a truck with a load rotation device according to the invention, seen from the front or one side.

In the accompanying drawings, a connecting l-rack, known per se, is designated as a whole with the reference numeral J, and the working parts provided at one end of this track 1 are designated with the numeral 2, although the details thereof will not be described here. It is shown.

At the other end of the track 1, a mast-shaped column 4 is supported on the track 1, which is rotatable about two wheels 3 having a relative distance from each other. on a carriage 5 which is movably guided via wheel elements 6 or other pivoting or sliding elements along two guideways 7 provided on the track 1 and extending along the normal direction of track movement; is provided with a frame supported at its lower part.

The guideway 7 is supported by support arms 8 and 9, respectively, which project forward from the rear of the truck chassis. Carriage 5 is actuated by a belt or chain drive mechanism or other suitable drive mechanism. belt or chain 10 and 1
1 run on pulley wheels 12 and 13 at the end of the path, which is the end position of the carriage 5, respectively. The belts or chains 10 and 11 are attached to the two rear pulley wheels 13.
It is driven by an electric or hydraulic motor 14 that transmits driving force to a pulley 16 via a belt or chain 15 to a wheel 17 attached to a drive shaft connected to the drive shaft. Two front wheel wheels 2 are mounted on a common axle axle 19 mounted on a beam 20 which, like the two chassis arms 8 and 9, protrudes forward from the rear chassis and the operating parts 2 of the truck. It is conveniently supported by □. Grooves 2 are provided between the chassis arms 8 and 9 and the beam 20, respectively.
0 and 21' are provided, these grooves being designed to accommodate the load-bearing fork arms 24 and 25 of the load-bearing fork arrangement 23, respectively. At the rear end, the load-bearing fork arrangement 23 has two upright parts 4'l' 26 connected to each other by transverse beams 28, 29.

27 to make the fork arrangement 23 rigid and act as a stop for the material handling equipment supported on the load-bearing fork arms 24.25. Load support fork device 2
3 is movably guided along the longitudinal direction of the upright column 4 by a hydraulically actuated cylinder arrangement 30 which extends and operates along the upright column 4. wrapped around the respective pulley wheels 33 and 34 attached to the cylinder arrangement 30 and connected to the load-bearing fork arrangement 30 or the vertical member 4 via their ends, respectively.
Chains 31 and 32 connected to portion 23A act as a movement transmission member and gear mechanism for cylinder 30, respectively, to raise and lower load-bearing fork member 23 in a known manner.

Furthermore, the upright column 4 is formed by two members provided at the upper free end of a generally U-shaped bar element 36, which is supported by the carriage 5 and has two free shanks 37 and 38, respectively bent upwards. It is configured to be able to rotate around a horizontal pivot shaft.

A rotating member 39, for example in the form of a plate, is mounted on the freely depending beam 20'' and can rotate about a substantially vertical axle 40. For example, an electric or hydraulic motor mounted below the plate 39 on the beam 20 drives the plate 39 which is rigidly connected to the l1ilI 140 via the chain transmission member 41. Although not shown in the accompanying drawings, it is also possible to use a drive mechanism equipped with a motor instead of a manual one. For example, upright member 43
and 44 extend above the rotary plate 39, the structure of which will be described below.

The function of the rotating mechanism 39 provided on the truck 1 described above and illustrated is as follows when handling equipment in the form of a pallet 45 in a warehouse. For example, the driver carries luggage 46.
The truck 1 is driven toward the center of the pallet 45, which is rotating so that the cargo can be easily received and taken, and then the two fork arms 24
．． The posts 4 provided along the two channels 21 and 22 are moved until the pallet 25 is below the pallet 45. If the lowest pallet 45 is raised and there is room for the truck 1 to advance below the pallet, the pillar 4 need not be moved. The pallet 45 is raised by fork arms 24, 25 which can be lowered straight down to the plane on which the truck I is stopped, and with the help of the columns 4 and the carriage 5 it is directed towards the rear or working part 2 of the truck by the guideway 7.
and descends onto the rotation mechanism 39 on the beam 20. The pallet 45 comes into position on the rest of the rollers 47, balls or other slide handles located on the upper surface of the beam 20 and/or the arms 8.9, the function of these elements being such that while the pallet 45 is rotating, is intended to reduce the interaction between the pallet 45 and the load bearing surface of the truck 1.

When the fork arm 24.25 is lowered towards the floor, the pallet/I5 rotates its center part) 39j
: and then the column 4 is pulled straight back from the pallet/15.

The plate 39 is then rotated through a desired angle, preferably 180 degrees, to rotate the load 46 toward the post 4. The support elements 43.4a on the plate 39 cooperate so that the side of the support 45A lies below it in the center of the pallet 45 while the pallet 45 rolls and rotates on the rollers 47. do it like this. After the rotation of the pallet 45 is completed, the pillar 4 is moved forward toward the pallet 45 again.

The pallet 45 is raised to the desired position and moved forward onto the columns 4 and carriage 5, returning the pallet 45 to its initial position 1, while the load 46 is pivoted outwardly into the warehouse aisle. After this lifting mechanism 23 has been lowered and the columns 4 have been withdrawn to the rear, a new load pallet is handled in the manner described above.

The invention is not limited to the embodiments described and illustrated above, but may be modified without exceeding the scope of the claims. Furthermore, it goes without saying that the mechanical device according to the invention is not limited to the type of truck described, but can also be applied to other types of trucks and lifting mechanisms.
