Description

Automatic feeding device and operating method thereof

The invention relates to an automatic feeding device and a working method thereof, in particular to an automatic feeding device capable of automatically clamping and separating a vertically stacked logistics box and a logistics box segment discharging device and a working method thereof.

The history of human development has always been closely related to logistics, such as the flow of goods from the agricultural society, the distribution of raw materials and products in the industrial and commercial society, the information technology e-generation business activities and international operations, such as the transformation of early Ganzi stores to online e-commerce and TV channel shopping, human life and logistics form an inseparable and dependent relationship. The case of the Czech Republic's 3PL logistics industry index, in addition to providing warehousing, transportation and fleet management services and the company's relationship partners, the company also introduced many e-logistics management systems and electronic communication systems.

The logistics center plays the role of a bridge between the manufacturer and the retailer. Although the logistics centers of different types are different in nature or scale, and the operating projects are different, the important operational functions of the logistics center can be summarized. When the supply truck arrives at the logistics center, after confirming the incoming goods through the "incoming goods" operation, the goods are stored in the warehouse, and then the stocks are well kept, and then the regular or irregular "counting" is applied.

After receiving the customer's order, the employee must first separate the vertically stacked logistics boxes one by one to facilitate the picking of different orders of goods to each logistics box. After that, the required items and barcodes must be first. Print and paste the item information to the logistics box. When the conveyor is transferred to the operator of the lower station, the sensor automatically detects the item information contained in the barcode. At this point, the required product electronic label will be displayed immediately to remind the picker, and the picker will perform the picking operation as indicated. After the job is completed, the product will be transferred to the next station via the conveyor. After the sealed operation confirms the approved items, the sealing operation is carried out, and the box items are sent to the stacking machine for stacking and storing operations, and finally the freight driver picks up the goods and distributes them.

Since the logistics boxes recovered after shipment are stacked vertically for space saving, the vertically stacked logistics boxes will make each logistics box more concatenated, so when stacking and separating by manual force, Very laborious and time consuming, in addition to the need to open more than one conveyor belt for placing and transporting several separated and separated logistics boxes, in order to facilitate the transport of the stacked logistics boxes, if not Conveyor belts must be handled by manpower. It can be seen that it takes a lot of manpower and time to prepare the logistics box for picking in advance. If this situation can be overcome, it will save manpower and unnecessary. spend.

The uppermost logistics box 41 of the box group 4, as shown in FIG. 7D, the grab box telescopic fasteners 37211 of the gripping body 3721 are respectively inserted into the grab holes 411 of the uppermost logistics box 41, and the fixing unit 38 The lower frame fastener 381 is inserted into the gripping hole 411 of the second layer flow box 41, and when the displacement unit 371 is raised, as shown in Fig. 7E, the lower layer fastener 381 is fixed to the lower layer. The logistics box, so that the uppermost logistics box 41 and the second layer logistics box 41 can be separated smoothly;

Thereafter, the displacement unit 371 will displace the grab unit 372 that has captured the log box 41 and align it with the second roller conveyor table 36, and at the same time, as shown in Fig. 7F, the lamination box under the fixed unit 38 The fastener 381 is separated from the grasping hole 411 of the second layer logistics box 41, and is moved up by the loading platform 33 so that the displacement unit 371 of the other group of uncaptured logistics boxes 41 can be aligned with the first The second layer logistics box 41, after which the displacement unit 371 will move down. As shown in Fig. 7G, the grabbing unit 372 that has taken the logistics box 41 must grasp the grab box telescopic fastener 37211 and the logistics box 41. The hole 411 is separated so that the log box 41 can be placed on the second roller conveyor table 36, while the other displacement unit 371 aligned with the second layer flow box 41 must be as shown in Fig. 7D. The grab box telescopic fastener 37211 of the grab body 3721 is inserted into the grab hole 411 of the second layer log box 41, and the laminate fastener 381 under the fixing unit 38 is inserted into the third layer log box 41. Take the hole 411 to continue the binning and grabbing operations;

The logistics box 41 placed on the first roller conveyor table 35 or the second roller conveyor table 36 is provided with at least one sensing around the first roller conveyor table 35 and the second roller conveyor table 36. The component (not shown) is mainly used to detect whether the logistics box 41 is placed on the first roller conveyor table 35 or the second roller conveyor table 36. If it is determined, the logistics box 41 is Shipped to the first picking line conveyor 5 or the second picking line conveyor 6 (at least one sensing element is also disposed around the first picking line conveyor 5 or the second picking line conveyor 6 for Detecting whether there is a logistics box output by the first roller conveyor table 35 or the second roller conveyor table 36), and the first picking line conveyor 5 or the second picking line conveyor 6 are all inclined Degree of belt conveyor (using a power drum), and the operating area of each group of power drums is just the size of a logistics box 41, to facilitate control and avoid collisions, and the first picking line conveyor 5 or the logistics box 41 outputted by the second picking line conveyor 6 is discharged by two picking The belt 7 is confluent, so one box and one box of exchange type confluence must be used to avoid the occurrence of material accumulation at the single conveying end. When the conveying has a malfunction, the conveyor belt is free to idling. At this time, the conveyor will automatically rotate for two seconds. stop.

In addition, after all the logistics boxes on the carrying platform 33 have been grasped, the lifting mechanism 36 will then control the loading platform 33 to move downward, so that the loading platform 33 is coupled to the clamping box conveyor belt 32, The supply group 4 that has not entered the clamping unit 3 and is placed on the feeding conveyor belt 1 can be automatically fed into the clamping unit 3 by the feeding conveyor belt 1 The loading platform 33 can further carry the next batch of supply box groups 4 for the next grab operation.

The flow chart of the method for operating the box according to the present invention is as shown in Fig. 8. The flow is as follows: (1) At the time of starting, a feed conveyor belt will be operated, and at least one of the plurality of logistics boxes can be The stacked supply group is placed on the feeding conveyor belt, so that at least one supply group that is stacked by several logistics boxes is automatically fed into the loading platform 801 of a clamping unit by the feeding conveyor; (2) The carrying platform of the clamping unit can lift the supply box to a certain height by a lifting mechanism, so as to be grasped by one side of the grabbing transfer mechanism and placed on one side and placed on one side a mode in which the uppermost logistics box of the supply group is separated from the logistics box of the second layer by 802; and (3) the separated logistics box is moved and placed on either side of the carrying platform.
