Its feeding mechanism is next to the manual operation platform. The system adopts transitional belt conveyor structure, thus increasing the complexity of the system.

The existing automated warehousing and logistics technology mostly uses tray-type sorting equipment. The automatic separation process of cargo pallets usually adopts a step-by-step method, that is, the current cargo pallet stays in the separation area, and the cargo or pallet is operated separately, such as grabbing and lifting the cargo by a manipulator (or forklift), and then transporting the pallet away , so as to realize the separation of the two. During this process, the conveying line needs to control the conveying flow of goods, that is, to ensure that the previous pallet of goods is separated before operating on the next pallet of goods. In this mode, the two adjacent separation processes require a long time interval, and at the same time, a complex mechanical structure is used to realize support and grasping, so there are disadvantages such as low work efficiency, difficulty in full-load operation, and inconvenient operation, which are greatly improved. Reduced operating efficiency of the system and increased operating costs.

Detailed ways

Further description will be given below in conjunction with the embodiments and accompanying drawings.

See accompanying drawings 1 and 2. The accompanying drawings show an embodiment of a conveyor with drawer pallets. It includes pallets, cargo extraction devices, conveyor belts, slides and controllers. The conveyor belt is divided into two sections, the front section is the receiving belt 1, and the rear section is the connecting belt 3; the section is set as a separation area, and the separation area One side is provided with a sub-conveyor belt 2 for recovering pallets; the separation area is provided with a group of separation rollers 10 sent forward and a group of separation rollers 9 vertically sent to the sub-conveyor belt, and the roller surface is lower than the roller surface; The slide bucket located at the end of the connecting belt is installed on the machine base, corresponding to the position of the storage bucket 5 set at the low position; the tray is a drawer-type tray 11, and there are two grooves 17 for separation on the bottom surface, and the groove 17 is connected with the separation roller. The position of the shaft 10 is adapted. The 4th, slide bucket, just opposite to Sheng Wu bucket 5. After receiving the object 12, the storage bucket 5 can be configured separately in the sorting and diverting area 6 as required, and can be distributed or self-collected. The conveyor belts are equipped with rollers 7 for connecting power and shaft rollers 8 for the conveyor belts arranged in a row. The separation shaft rollers and separation roller groups of each conveyor belt and separation zone are independently driven by the motor device and centrally controlled by the controller.

The drawer tray shown in Fig. 2 has three supporting blocks 16 for supporting and sliding on both sides of the groove 17. The left and right support (shaft) gears can also be adjusted in the front and rear directions to meet the support needs of goods of different sizes.

In this separating device, when advancing to the breakaway point of the separating area, the pallet falls, and the chamfering inclined surface 18 will facilitate the pallet to slide down in place and fall onto the separation roller group 9 . These two grooves 17 for separation on the bottom surface make room for separation and movement of the pallet. It is also convenient to leave space for the travel of the manipulator and linear motor when picking the pallet item assembly from the stack.

The front of the drawer tray is a bucket panel 13 with side panels 14 on both sides. On the bucket panel 13, a magnet 19 is arranged outside the center, which is used for controlling the clutch when the manipulator puts the stacked objects. It can be attracted by the electromagnet when the manipulator picks up the goods.

Fig. 3 is a structural view from the opposite direction of the drawer tray in Fig. 2 . Bucket panels 13 and support stops 16 are shown. The bottom both sides of the side plate of the drawer tray are provided with chamfered slopes 18 with an inclination angle of 30 degrees. This arrangement also facilitates precise positioning of the pallet at the rack storage unit (not shown in the figures).

The working process of this device is briefly described as follows:

When working, first remove the drawer tray and the object assembly from the stack, and take the receiving belt from the upper belt A of the object, and the receiving belt runs along the logistics direction B, and sends the assembly to the separation area;

After the components arrive at the separation area, the tray's escape groove makes the tray drop to the side C-direction roller by its own gravity, while the goods fall to the forward B-direction roller, and the automatic separation of the two is realized by the rotation of the rollers in different directions . The objects are continuously pushed to the receiving belt, and the objects are forwarded along the D direction;

At this time, the drawer tray is sent to the sub-conveyor belt along the C direction by the separation roller group that is started/running, so as to realize the recovery and separation of the tray;

The objects reach the end of the connecting belt, enter the storage hopper downward from the slide, and then divert the objects in the E direction.

In this embodiment, the running gear in the rack and the stacker running gear (mechanism) is driven by a linear motor and operated by electric remote control. Linear motors include cylindrical linear motors for up and down and steering, linear motors for telescopic fetching and linear motors for traveling devices for translation.

Fig. 4 is exactly the control type stacker traveling device that is matched with conveyor belt. The device is a column frame translation lifting structure. It is installed in front of the vertical shelf, and moves in parallel along the guide rails set up and down. The manipulator is installed on the vertical bar with the upper and lower guide rail wheels to move up and down to take the position. After positioning, it is extracted from the cargo space, then descends, and translates to the side of the conveyor belt. And turning, put the box-like items on the belt with the pallet.

Figure 5 shows a schematic structural view of the stacker manipulator. The manipulator grabs the goods in the form of an electromagnet 20 to attract the pallet, and a roller stage 24 is provided to support the goods. When picking up the goods, the electromagnet support 21 is driven by the motor and stretches into the shelf along the telescopic track 22 of the manipulator. The trays have been stacked in advance in the shelf. After positioning, the electromagnet coils are energized to attract the permanent magnets 19 on the tray and drag the goods. On the loading platform 24, the pallet of goods is sent to the conveyer belt by the running mechanism of the stacker, and the process of leaving the warehouse of the goods is completed.
