Please refer to fig. 1 to 7. The material arranging and stacking mechanism comprises a buffer lifter 1, a vibration disc 2, a differential conveying device 3, a material pressing belt 4, a first detection sensor 51, a conveying line 6 and a controller 7.

The buffer lifter 1 is used for buffering the product to be processed and stacked and lifting the product into the vibration disc 2. In this embodiment, the product to be treated and stacked is a soft package magnetic rod sleeve 9. The magnetic rod sleeve supplies materials in a box or a large package. The buffer hopper 11 of the buffer lifter 1 is in an inverted cone shape, so that products can flow to the bottom of the hopper after being poured. The buffer hopper 11 is designed to be of a specific size according to the size of the actual product and the discharging beat. The buffer hopper 11 of the present embodiment can buffer five thousand packets of magnetic rod sleeves for 1 second/packet of beats. The bottom of the buffer storage hopper 11 is also provided with a photoelectric sensor to detect whether the material is needed to be supplemented, and if the material shortage is detected, the material supplement is prompted through an audible and visual alarm. The feeding end of the lifter 12 of the buffer lifter 1 extends into the bottom of the buffer hopper 11, and is lifted upwards from the bottom of the buffer hopper 11 at an angle of 45 degrees, so that the magnetic rod sleeve can be lifted from the bottom of the hopper to the feed opening above the vibration disc 2 in a relatively stable amount.

The vibrating tray 2 is used for conveying products to be processed and stacked to the differential conveying device 3. The vibration dish 2 can evenly feed, and in this embodiment, the outside of vibration dish 2 is equipped with guard shield 21, and the ejection of compact speed beat of vibration dish 2 is 1 second/package, and through the vibration of vibration dish, the bar magnet cover rises along spiral track. Since the flexible package of the magnetic rod sleeve is a plastic self-sealing bag, if too much product is in the vibrating tray body, the amount of the product in the tray body is controlled by the buffer lifter 1. Preferably, a second detecting sensor 52 is provided inside the vibration plate 2 for detecting the amount of material in the vibration plate. The input end of the controller 7 is connected with the signal output end of the second detection sensor 52, and is used for controlling the feeding speed of the buffer lifter 1 according to the detection result of the second detection sensor 52. If the product amount in the vibration disc body is too small, the discharging beat of the vibration disc can be influenced, and when the second detection sensor 52 detects that the product amount in the disc body is too small, the controller 7 can accelerate the motor rotation speed of the elevator 12, increase the feeding speed and ensure the discharging beat of the vibration disc. If there is too much product in the vibratory pan, the controller 7 will slow down the motor speed of the elevator 12 or stop the lifting, thereby controlling the amount of product in the pan. The soft package magnetic rod sleeves are screened by a series of tracks or changed in posture in the ascending process, and finally the unordered soft package magnetic rod sleeves are automatically, orderly, directionally and orderly arranged and accurately conveyed to the differential speed conveying device 3. In one particular embodiment, the second detection sensor 52 includes two sets of photosensors, one set near the bottom of the vibrating tray and the other set near the top of the vibrating tray.

In the present embodiment, the differential conveying device 3 includes a slow belt 31 and a fast belt 32, the slow belt 31 being located between the discharge port of the vibration plate 2 and the feed end of the fast belt 32. The magnetic rod sleeve output by the vibration disc 2 is pulled away from the gap through the speed difference between the two groups of conveyor belts, so that the follow-up product counting is facilitated.

The material pressing belt 4 is arranged above the rear end of the differential conveying device 3 so as to apply pressure to the material to be processed and stacked on the differential conveying device 3, so that the heights of the products are nearly consistent, and the subsequent processing is convenient. In the present embodiment, a pair of guide plates 41 are provided on both sides of the pressing belt 4, respectively, and fix the conveying direction of the soft package magnetic rod cover by guiding on both sides. The surface of the pressing belt 4, which is contacted with the product to be processed and stacked, is provided with a sponge 42 to prevent the soft package magnetic rod sleeve from being pressed and damaged in the moving process.

The first detection sensor 51 is disposed at a position close to the discharge end of the differential conveying device 3, and is configured to send a detection signal to the controller 7 when detecting that the differential conveying device 3 outputs a product to be processed and stacked to the conveying line 6, so as to realize a counting function. Alternatively, the first detection sensor 51 is a photoelectric sensor.

Preferably, the top of each pair of partition plates 62 is turned outwards to form a horn-like opening so as to better receive the soft package magnetic rod sleeve 9 and prevent the phenomena of blockage and blockage.

Further, the two sides of the chain plate line 6 are provided with 304 stainless steel baffles 63 with the thickness of 1mm, so that the product is prevented from flying out. The link plate wire 6 is also provided with a protective cover 64.

The controller 7 is configured to count the products to be processed and stacked outputted from the differential conveying device 3 to the conveying line 6 according to the received detection signal of the first detection sensor 51, and control the conveying line 6 to move forward by a predetermined distance whenever the number of the products to be processed and stacked outputted reaches a predetermined value, so that the next receiving portion 60 receives the products to be processed and stacked outputted from the differential conveying device 3.

In the present embodiment, the controller 7 controls the conveyance of the link 6 forward every time the controller 7 counts that three flexible package magnet bar sleeves 9 are conveyed to the link 6. The chain plate line 6 outputs three soft package magnetic rod sleeves 9 stacked together to be supplied to a subsequent boxing and feeding mechanism. Optionally, a photoelectric sensor 53 is arranged at the discharge end of the chain plate line, and after a material-containing signal is detected, a subsequent boxing and feeding mechanism is controlled to put the soft packaging magnetic rod sleeve stacked by three bags into a packaging box.
