Description

Technical Field

[0001] The invention relates to a loading machine, belonging to the technical field of logistics loading machines. Background Art

[0002] At present, palletizing equipment and intelligent warehousing equipment have been widely popularized and improved day by day, but the subsequent loading logistics and transportation links are still relatively backward. The current automated loading equipment basically stays at the level of single-package or single-stack loading, that is, during the loading process, it is either for a single packaging unit or a single fully loaded pallet unit, and it is loaded back and forth one by one. In particular, single-package vehicles are not only inefficient, but more fatally, they also need to depalletize the stacked materials to make them into single packages, and then load the single packages. Due to the additional depalletizing link, the equipment occupancy area increases, resulting in a sharp decrease in the warehouse area. With more links, the number of fault points also increases accordingly, and the equipment investment cost increases. Whether it is an AGV navigation forklift or a truss type, single-stack loading has repeated accumulation of empty return trips, resulting in many problems such as low loading speed, low bag loading rate, and long vehicle occupancy time.

[0003] Based on the above statements, it is urgent to propose a machine that can load stacked goods into a whole truck at one time to solve the problem of low efficiency of existing material loading. Summary of the invention

[0004] In order to propose an efficient, multifunctional, fully automatic palletizing and loading integrated machine to solve the problem of low efficiency of existing material loading, a brief overview of the invention is given below to provide a basic understanding of certain aspects of the invention. It should be understood that this overview is not an exhaustive overview of the invention. It is not intended to identify the key or important parts of the invention, nor is it intended to limit the scope of the invention.

[0005] The technical solution of the present invention:

[0006] A vehicle loading machine comprises a pallet conveying unit, a shaping and stacking unit, an appearance detection unit, a defective product offline unit, a stacking and marshaling unit, a loading platform, a front door assembly, an adjustment mechanism and a vehicle positioning device. The pallet conveying unit, the shaping and stacking unit and the defective product offline unit are arranged and installed in sequence, the appearance detection unit is installed at the periphery of the defective product offline unit, the next process of the defective product offline unit is installed with a stacking and marshaling unit, the stacking and marshaling unit is installed at one end of the loading platform, the other end of the loading platform is installed with a front door assembly, the bottom of the loading platform is installed with an adjustment mechanism, and the vehicle positioning device is used to achieve height and position alignment of the vehicle to be loaded.

[0007] The present invention has the following beneficial effects:

[0008] 1. The present invention proposes a vehicle loading machine, which has the following main features: fully automated operation, simple equipment composition, efficient operation, flexible operation, cost saving, and multi-functions;

[0009] 2. The present invention proposes a vehicle loading machine that, when performing automated equipment operation, can shape and stack the goods in pallets conveyed by the pallet conveying unit and tighten them in the width direction by the palletizing unit to make the goods in pallets flat, and then pass through the appearance detection unit for detection, wherein the unqualified goods in the pallet are automatically removed from the line by the unqualified product removal unit, and the qualified goods in the pallet are grouped by the stacking and grouping unit, and then are pushed onto the loading platform as a whole, and when the goods on the loading platform reach the amount of a whole box, the loading platform transports the goods as a whole to the container or the compartment of the vehicle, completing the one-time loading operation; unlike the existing loading technology, when the existing goods are loaded, the vehicle needs to wait, and can only drive away after the goods are installed in sequence, while the vehicle loading machine of the present invention realizes the loading process, and the vehicle does not need to wait, and the vehicle is loaded at one time, which completely solves the problem of low material loading efficiency;

[0010] 3. The adjustment mechanism of the present invention can adjust the loading platform with three degrees of freedom, namely, height adjustment, lateral adjustment and center adjustment. The height adjustment is achieved through the adjustment base of the adjustment mechanism. Specifically, the adjustment base drives the lateral adjustment mechanism and the center adjustment mechanism in front and behind, so that the height direction of the loading platform matches the vehicle to be loaded, thereby achieving the height alignment of the entire platform and the vehicle. In addition, under the action of lateral adjustment and center adjustment, the loading platform and the vehicle compartment are completely aligned, so that the stacked objects on the loading platform can be smoothly and once entered into the vehicle compartment. The whole process is smooth, the front and rear connections are smooth, smooth, accurate and efficient.

[0011] 4. The whole machine of the present invention realizes automatic logistics loading through the pallet conveying unit, shaping and stacking unit, appearance detection unit, unqualified product offline unit, stacking and marshaling unit and loading platform in sequence. The whole mechanical equipment is flexible in operation, high in accuracy and high in work efficiency.

[0012] 5. The shaping and stacking unit of the present invention can shape and tighten the stacked objects. The tightening transmission mechanism is lifted and lowered inside the first roller conveyor to tighten the two stacked objects, so that the stacked objects on the rear loading platform have the characteristics of high neatness. The ingenious structure of the shaping and stacking unit replaces the manual operation of mechanical forklift for stacking, and has the characteristics of high automation and strong practicality.

[0013] 6. The vehicle positioning device of the present invention can accurately align the vehicle so that the floor of the vehicle compartment is parallel to the base plane of the loading platform, so that the slide assembly on the loading platform drives the stacked objects to be loaded onto the vehicle at one time. Under the action of the vehicle positioning device, the loading process of the stacked objects is smoother;

[0014] 7. The machine of the present invention is ingenious, flexible, and easy to install. It can realize automatic compacting and stacking of stacked objects, and complete the loading of stacked objects into trucks at one time. It has the advantages of strong practicality and high cost performance. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical scheme and advantages of the present invention clearer, the present invention is described below by the specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0047] The connection mentioned in the present invention is divided into fixed connection and detachable connection. The fixed connection (i.e., non-detachable connection) includes but is not limited to conventional fixed connection methods such as folding connection, rivet connection, bonding connection and welding connection. The detachable connection includes but is not limited to conventional detachable methods such as threaded connection, snap connection, pin connection and hinge connection. When the specific connection method is not clearly defined, it is assumed that at least one connection method can always be found in the existing connection methods to achieve the function. Those skilled in the art can choose according to their needs. For example: welding connection is selected for fixed connection, and hinge connection is selected for detachable connection.

[0048] Specific implementation method 1: refer to Figure 1-Figure 30 The present embodiment is described. A whole vehicle loading machine of the present embodiment comprises a pallet conveying unit 1, a shaping and stacking unit 2, an appearance detection unit 3, a defective product offline unit 4, a stacking and marshalling unit 5, a loading platform 6, a front door assembly 7, an adjustment mechanism 8 and a vehicle positioning device 9. The pallet conveying unit 1, the shaping and stacking unit 2 and the defective product offline unit 4 are arranged and installed in sequence, the appearance detection unit 3 is installed on the periphery of the defective product offline unit 4, the next process of the defective product offline unit 4 is installed with a stacking and marshalling unit 5, the stacking and marshalling unit 5 is installed at one end of the loading platform 6, the other end of the loading platform 6 is installed with a front door assembly 7, the bottom of the loading platform 6 is installed with an adjustment mechanism 8, and the vehicle positioning device 9 is used to achieve height and position alignment of the vehicle to be loaded.

[0049] The stacked goods supplied by the front-end palletizing system or the outbound system of the stereoscopic warehouse are transported by the parallel pallet conveying unit 1 (the number of parallel columns multiplied by the width of the goods stack is slightly less than the inner width of the vehicle). The parallel pallet conveying unit 1 transports the stacked goods to the shaping and stacking unit 2, and then the shaping and stacking unit 2 performs shaping on the stack, focusing on making the stack tight in the width direction, and the front and rear sides are basically coplanar. After that, the appearance inspection unit 3 performs appearance inspection on the goods. The unqualified ones are automatically removed from the line by the unqualified product removal unit 4, and the qualified ones are transported to the push stacking marshalling machine 5. After several reciprocating pushes, the stacked goods to be loaded in a whole vehicle are pre-assembled on the loading platform 6, and lined up to wait for the vehicle to arrive for loading. After the vehicle is in place, the rear of the frame first enters the guide groove of the vehicle positioning device 9, and the rear plane is completely in contact with the fixed guide groove vertical plate, so that the center of the vehicle is preliminarily determined. Then the vertical positioning lifting cylinder 93 of the vehicle positioning device 9 is lifted up to make the bottom plate of the car body parallel to the base plane. Then, the adjustment mechanism 8 is used to adjust the loading platform 6 laterally and centrally, and the loading platform 6 is operated to rotate so that the loading platform 6 is completely aligned with the vehicle in the width direction and the platform centerline. At this time, the adjustment base 83 of the adjustment mechanism 8 drives the loading platform to rise or fall, and completes the docking of the loading platform with the vehicle floor in the height direction. After that, the locking hook 753 of the locking mechanism 75 hooks the main crossbeam at the rear of the frame under the drive of the locking cylinder 752, and completes the locking of the vehicle.

[0050] Next, the slide assembly 62 on the loading platform 6 extends into the carriage together with the pre-assembled cargo. During the cargo movement, the cargo is squeezed and shaped by two vertical shaping drums 72 on the door frame of the front door assembly 7 to ensure that the cargo can enter the carriage smoothly. After the cargo has completely entered the carriage, the material blocking plate 74 in the front door assembly 7 drops to a low position, then extends forward, pushing the cargo on the slide assembly 62 forward and against the front wall of the carriage. At this time, the slide assembly 62 is pulled out backward, and the forward-extended material blocking plate 74 blocks the cargo in the carriage. After the slide assembly 62 returns to the initial position, other mechanisms or devices also return to the initial state in turn, and loading is completed at one time. After that, the loading platform 6 can continue to load the pre-assembled cargo.

The cams 2153 act on the lifting seat 2130. Since the lifting guide wheel 2138 of the tightening seat 2131 slides in the shaping lifting guide rail 216, the tightening seat 2131 can realize the up and down lifting action relative to the lifting drive base 211, and the first roller conveyor 212 is installed on the lifting drive base 211, and the tightening motor 2132, the tightening transmission shaft 2133, the tightening main sprocket 2134, the tightening slave sprocket 2135, the tightening chain 2136 and the tightening slave sprocket mounting seat 2131 are installed. 37, wherein the tightening slave sprocket mounting seat 2137 is installed between the rollers of the first roller conveyor 212, when the tightening seat 2131 is lifted relative to the lifting drive base 211, the height of the horizontal plane where the tightening slave sprocket mounting seat 2137 is located is higher than the height of the horizontal plane where the first roller conveyor 212 is located, at this time, the tightening motor 2132 drives the tightening main sprocket 2134 to rotate through the tightening transmission shaft 2133, and the tightening main sprocket 2134 drives the tightening slave sprocket 2135 to rotate through the tightening chain 2136, and the stacked objects that slide onto the first roller conveyor 212 are driven by the tightening slave sprocket 2135 to be pulled together to one side, and since there are two shaping adjustment units 21, at this time, the stacked objects on the shaping adjustment units 21 can achieve relative tightening.
