Technical Field
[0001] The invention relates to the field of storage equipment, and in particular to an automatic rotary shelf. Background Art
[0002] With the rapid development of the logistics industry, the application of automatic rotary shelves is becoming more and more popular. The guide rails of existing automatic rotary shelves are connected in sections. When some of the guide rails have height deviations, the movement of the pallets above the guide rails will produce noise, increase wear and reduce service life. At the same time, existing shelves have the problem of inconvenience in taking things. Summary of the invention
[0003] In order to overcome the above-mentioned shortcomings, the object of the present invention is to provide an automatic rotary shelf with low noise during operation, which can improve the convenience of taking things.
[0004] In order to achieve the above purpose, the technical solution adopted by the present invention is: an automatic carousel shelf, comprising a bracket assembled by a crossbar and a vertical bar, wherein a plurality of layers of mutually independent guide rail assemblies are distributed up and down in the bracket, wherein the guide rail assemblies of each layer include two parallel guide rails fixed on the bracket, wherein the guide rails are formed by welding a plurality of guide rail components end to end and polishing the surface, and a support plate is provided on the bracket where the outer side of each guide rail is located;
[0005] Discs are provided at the ends of the guide rails, and the discs are located between the two guide rails; an arc-shaped guide plate connected with two support plates is provided on the bracket where the outer side of the disc is located; a bearing is provided at the center of the disc, and a rotating shaft is inserted in the bearing, and the rotating shaft is installed on the bracket through a bearing seat; a gear that rotates synchronously with the disc is provided on the disc, a chain is provided between the two gears, and one of the gears is connected to the driving motor to realize the synchronous rotation of the two gears. An inner slideway is formed between the guide rail and the disc, an outer slideway is formed between the support plate and the arc-shaped guide plate, and an annular slideway for the chain plate to move is defined between the inner slideway and the outer slideway, and the chain is fixedly connected to the chain plate; a tray for placing items is provided on the chain plate.
[0006] The present invention can reduce the height difference caused by each segmented guide rail by welding the segmented guide rail into a whole section of guide rail, which is beneficial to the smooth operation of the pallet and reduces the noise generated by the movement of the pallet on the chain plate. Each layer of guide rail components adopts an independent operation mode, that is, a driving motor drives a plurality of pallets on a layer to run in a ring shape, and a plurality of picking points can be set outside the shelf. Each picking point corresponds to a layer of annular slideway, and the picking between each layer will not interfere with each other, thereby improving the convenience of picking up items from the shelf.
[0007] Furthermore, a limiting groove is provided on the upper end surface of the chain plate, a horizontally placed rotating shaft is provided on the lower end surface of the pallet, and rollable rollers are provided at both ends of the rotating shaft; the rollers are placed in the limiting grooves. The rotating shaft can be directly fixed on the pallet, or a bearing can be installed on the rotating shaft and the bearing can be fixed on the pallet. Under normal circumstances, the number of rotating shafts is two, the number of rollers is four, and the number of limiting grooves is four.
[0008] Preferably, the roller includes a bearing and a bearing sleeve, wherein the bearing sleeve is coated on the outer end of the bearing, and the bearing sleeve is made of nylon or polyurethane. Coating the bearing sleeve made of nylon or polyurethane on the outer end of the bearing can reduce vibration and eliminate noise.
[0009] Furthermore, a plurality of slots are distributed in a circular array at the edge of the disk, and a positioning plate is fixedly arranged on the disk where the outer edge of the slot is located; the guide rail is arranged above the disk, and a clamping plate capable of being embedded in the slot is arranged on the chain plate on one side of the guide rail. By inserting the clamping plate into the slot, the chain plate can be positioned as the disk rotates, thereby improving the stability of the chain plate running at the disk.
[0010] Preferably, an auxiliary plate is provided on the bracket above the guide rail, and the auxiliary plate is arranged parallel to the guide rail; and a lap plate movable on the auxiliary plate is provided on the chain plate. The design of the auxiliary plate further improves the stability of the chain plate running on the guide rail.
[0011] Furthermore, the chain plate is a toothed chain plate, which transmits power through the meshing of the working chain plate with the involute tooth profile of the sprocket teeth. This mode operates smoothly and with low noise.
[0012] Furthermore, the bracket is made of steel or steel plate, and an anti-rust layer is provided on the surface of the angle steel, which is galvanized or sprayed.
[0013] Compared with the prior art, the present invention has the following beneficial effects: by welding the segmented guide rails into a whole guide rail, the noise generated by the movement of the pallet on the chain plate due to the height difference between the segmented guide rails can be reduced; at the same time, the roller with a complex structure and numerous components is transformed, and the roller after the transformation is composed of a universal bearing and a bearing sleeve, which has a simple structure, efficient operation and low failure rate; the operation of each layer of guide rail components does not interfere with each other, thereby improving the convenience of taking and placing objects.
