Abstract

The device is designed for loading and folding pallets with skids between plane the floor and the loading plane is driven by roller track. The loading and unloading of the pallets is carried out pallet truck. Getting Started the single drive has rollers with three separated by cylindrical support surfaces, between which are two fixed planes for pallet truck wheels. Vertical lifting and starting the track is done by a scissor lift self-propelled. The device will be preferred used for revenue and shipping lines warehouses with shelf stackers.

Description

(54) Approach and lift driven roller conveyor

The machine is designed for loading and unloading pallets with skids between the floor plane and the loading plane of the driven roller track. Pallet loading and unloading is carried out with a pallet truck. The self-propelled approach track has rollers with three separate cylindrical bearing surfaces, between which there are two fixed planar tracks for the forklift wheels. The self-propelled scissor lift is used to raise and lower the track vertically. The equipment will preferably be used for receiving and shipping lines of warehouses with shelf stackers.

The invention relates to an approach and a lift driven roller conveyor, on which skid pallets are transported to or from a pallet truck.

The previously used driven roller tracks have a certain stable height above the floor (for example 500 mm) and therefore the pallet must be loaded or unloaded using a forklift. For industrial plants and warehouses where pallet trucks are used, the system is not suitable. In the present case, the disadvantage of the necessity of a forklift is eliminated by the apparatus of the invention, which is explained in more detail in the accompanying drawing, in which Fig. 1 is the approach and lift driven roller track in the lowest position; Fig. 3 is a longitudinal vertical section of the plane track of the roller track; and Fig. 4 is a transverse vertical section of the roller and plane track of the roller track.

The approach and lift driven roller track 6 has as a support and conveying device for the skid pallet 11 a plurality of driven rollers, each having three larger equal cylindrical surfaces 10 for supporting and transporting the pallet 11 and two smaller equal cylindrical surfaces 50 connecting the roller in one. whole. The space above the two smaller diameters of the rollers 10 is used to accommodate two fixed planar tracks 8 for the travel of the pallet truck. Every second roller has in its middle part two conical collars 13 for guiding the middle rail of the pallet 11.

The approach driven roller track 4 is attached to the hydraulic scissor lift platform 8 to compensate for the height difference between the floor and the beginning of the line with stable driven roller tracks 12. The hydraulic lifting mechanism is formed by a pair of lever shears £ a hydraulic cylinder 4 by means of an electromotive hydraulic aggregate 4 and an electrical distributor 6. In the lowest position, the upper plane of the support rollers and both planar tracks must be in the plane of the floor, and therefore the structure of the entire device is embedded in a concrete pit in the floor. Due to the necessity of two-sided side access (installation and maintenance), the pit is extended from both sides of the pit according to the possibility of construction. This space is covered by two hinged lids 8.

Working procedure for loading pallets on the track: The approaching roller track 4 and the lifting platform 4 are in the lowest position, at the floor level. The pallet truck 11 with pallet 11 travels on a flat track 8 of the track, folds the pallet 11 onto rollers 8 and leaves the empty pallet. The lifting platform 4 then lifts the track 4 to an adjustable top position, i.e. to a height such that the rollers 4 are at the same level as the rollers of the fixed fixed roller track 6. The rollers of the approaching track 6 and the adjacent stable track 12 are switched on and the pallet 11 moves to track 12 and continues to move.

Working procedure for unloading pallets from the track: The approaching roller track 4 is in the highest position, i.e. at the level of the continuous fixed driven roller track 12. The pallet 11 moves from this track 12 to the rollers 6 of the approaching roller track 6 and stops. The lifting platform 4 slides down from the approach track 4 including the pallet 11 vertically down to the lowest position. Below the pallet 11 on both planar tracks 4, the approaching roller track 6 is driven by a pallet truck, lifts the pallet 11 and leaves with it.

Approaching and lifting driven roller tracks can be used, for example, for stable driven roller tracks of sets of reception and expedition lines used in warehouses with shelf stackers.

Claims (1)

SUBJECT OF THE INVENTION Self-propelled drive-in and lift-mounted roller track attached to a self-propelled scissor lift for height adjustment, for example between the lowest floor-level position and the highest adjustable position, characterized in that each roller has three separate supporting cylindrical surfaces (4) of the same diameter and between them two cylindrical surfaces (10) of the same smaller diameter, above which are located two fixed planar bearing tracks (3).
