Description
Technical Field
The invention relates to the field of placement of logistics express items, in particular to an automatic lifting placement frame for the logistics express items.
Background
The packaging box with the product is wrapped by the plastic woven bag, two ends of the plastic woven bag are thermally sealed, and then the plastic woven bag is labeled, so that the packaging box needs to be stored on a goods shelf to be delivered.
Because the goods shelf has a certain height, the traditional storage mode is that people cooperate, one person transfers the packing box to the goods shelf from the lower part, and the other person places the packing box on the goods shelf; however, the labor intensity of workers is too high, particularly, the labor intensity of workers delivering the packing cases below is higher, and the potential safety hazard that the packing cases fall off also exists.
For solving this problem, adopt the crane to promote the packing box to the goods shelves top now often, put by the manual work packing box on to the crane again, but because the crane promotes the front needs the manual work to put the packing box to the crane, though reduced potential safety hazard and intensity of labour, but store the packing box to the efficiency on the goods shelves not high, and intensity of labour is still great.
Disclosure of Invention
The invention aims to provide a lifting placing frame which is beneficial to improving the goods storage efficiency and reducing the labor intensity.
In order to achieve the purpose, the technical scheme of the invention provides an automatic lifting and placing frame for logistics express delivery pieces, which comprises a rack, a conveyor belt, a lifting mechanism and a blocking and squeezing mechanism, wherein the lifting mechanism comprises a lifting table, the lifting table is positioned at one end of the conveyor belt and can be positioned on the same plane with the conveyor belt; hinder crowded mechanism and hinder crowded unit including hindering crowded board and two, two hinder crowded unit and are located conveyer belt one side separately, every hinders crowded unit and all includes the screw rod No. one, the slider, support bar and spacing strip, No. one the screw rod rotates and sets up in the frame, slider and screw rod threaded connection No. one, the one end and the slider of support bar rotate to be connected, the one end and the frame of spacing strip rotate to be connected, the other end and the middle part of support bar of spacing strip rotate to be connected, it is protruding type to hinder crowded board, it is located between two support bars and hinders crowded board and two support bar fixed connection to hinder crowded board, when elevating platform and conveyer belt are located the coplanar, it is in the horizontal plane to hinder crowded board.
The technical effect of the scheme is as follows: when the lifting platform and the conveyor belt are positioned on the same plane, the goods are conveyed to the lifting platform through the conveyor belt and below the extrusion resisting plate, and are lifted to the goods shelf by the lifting platform, and the goods are placed by personnel on the goods shelf.
When the elevating platform ascends, the first screw rod rotates to drive the sliding block to move, so that the support bar in the horizontal state is driven to move and the extrusion blocking plate is driven to move, the support bar in the horizontal state and the extrusion blocking plate are gradually in the vertical state under the action of the limiting bar, the extrusion blocking plate is changed from the horizontal state to the vertical state, goods on the conveying belt are pushed to move towards the opposite direction of the operation of the conveying belt by the extrusion blocking plate, the distance between the goods under the friction action of the conveying belt and the thrust action of the extrusion blocking plate is reduced, and the goods are more compact.
When the lifting platform descends, the first screw rod rotates reversely to drive the sliding block to move reversely, so that the extrusion blocking plate in a vertical state is driven to change posture to be in a horizontal state, when the lifting platform and the conveying belt are located on the same plane again, the goods with smaller distance on the conveying belt are conveyed to the lifting platform, the goods do not need to be conveyed to the lifting platform manually, the labor intensity is reduced, after the distance between the goods is reduced, the quantity of the goods conveyed to the lifting platform to be lifted is increased every time, so that several goods are lifted every time, the efficiency is obviously improved when tens of thousands of goods are lifted, and the storage efficiency of the goods is improved.
In the process that the horizontal state of the extrusion preventing plate is changed into the vertical state, the extrusion preventing plate extrudes one end of one packaging box close to the extrusion preventing plate to rotate, so that the plastic woven bag at the other end of the packaging box is warped, and in the process that the subsequent packaging box moves on the conveying belt, the head end of the plastic woven bag can move along the lower part of the plastic woven bag warped with the warped foot, so that the tail end of the plastic woven bag is pulled to warp upwards, and the packaging boxes are sequentially closer; when the lifting platform and the conveyor belt are located on the same plane, more cargos are transferred to the lifting platform in unit time, and therefore the cargo storage efficiency is improved.
Further, elevating system still includes bottom plate and two elevating unit, every elevating unit all includes Z section bar and two lift portions, Z section bar slides and sets up on the bottom plate, two lift portions are located the one end of Z section bar separately, every lift portion all includes a gear, rack and two lift bars, the one end of two lift bars is articulated mutually, the other end of two lift bars is articulated with bottom plate and elevating platform separately, a gear and lift bar fixed connection, rack and Z section bar fixed connection, and rack and gear engagement No. one. The technical effect of the scheme is as follows: the sliding process of the Z-shaped strips drives the first gear to rotate through the racks, so that the two lifting strips are driven to rotate, and the lifting platform is driven to lift.
Further, still include servo motor, No. two screw rods, draw runner and cingulums, servo motor is fixed to be set up in the frame, No. two screw rods and servo motor's output shaft, and the draw runner is located between two Z profiles and draw runner and two Z profile fixed connection, and draw runner and No. two screw rod threaded connection all have No. two gears with coaxial coupling on screw rod and No. two screw rods, and each No. two gears pass through the cingulums and connect. The technical effect of the scheme is as follows: the servo motor can drive the lifting platform and the extrusion-resistant plate to operate simultaneously.
Further, the toothed belt can be in contact with the conveyor belt. The technical effect of the scheme is as follows: causing the belt to flutter and shaking off dust on the belt.
Furthermore, a limiting block is arranged on the bottom plate, and the Z-shaped strip is connected with the limiting block in a sliding mode. The technical effect of the scheme is as follows: the stability of Z-shaped strip moving is improved.
Furthermore, a scanner is arranged on the extrusion resisting plate. The technical effect of the scheme is as follows: when the extrusion-resistant plate is positioned on the horizontal plane, goods pass through the lower part of the extrusion-resistant plate, so that the goods can be scanned conveniently.
