drive sprockets

320a, 320b, three driven

sprockets

330a, 330b, 330c, spacers 340, and a base plate 350.

The chain 310 also passes between the upper rotary disk 210 and the lower rotary disk 220. The chain 310 is sequentially sleeved on the driving sprocket 320a, the driven sprocket 330a, the driving sprocket 320b, the driven sprocket 330b and the driven sprocket 330c to form a cycle.

The driving sprocket 320 moves the chain 310 and simultaneously rotates the driven sprocket 330.

The spacers 340 are equidistantly fixed to the chain 310 to move with the chain 310. The bottom plate 350 is disposed below the chain and at the rear side of the conveying direction of the turntable assembly 200.

Fig. 7 is an enlarged view of a portion II of fig. 2.

As shown in fig. 7, the push-in assembly 400 includes: a vertical lifting mechanism 410, a horizontal moving mechanism 420 and a pushing head 430.

The pushing head 430 is moved in a circular motion, and the position of the pushing head 430 in fig. 7 is assumed as an initial position. The vertical lift mechanism 410 drives the push-in push head 430 to move downward, and when the push-in push head 430 reaches the position of the sanitary napkin product W, the vertical lift mechanism 410 stops operating. The horizontal moving mechanism 420 is pushed forward at this time, pushing the sanitary napkin product W into the receptacle 510 of the inverting assembly 500.

Then, the horizontal moving mechanism 420 stops operating, the vertical lifting mechanism 410 moves the pushing head 430 upwards, and then the horizontal moving mechanism 420 recovers to drive the pushing head 430 to return to the initial position.

In this embodiment, the main function of the vertical lifting mechanism 410 is that after the sanitary napkin product W is pushed into the pushing head 430, the intermediate conveying assembly 300 can move simultaneously to move the next group of sanitary napkin products W to the pushing position in the process of returning to the initial position, so as to improve the working efficiency.

Of course, the pushing assembly 400 may have only the horizontal moving mechanism 420, and the pushing head 430 only performs the back-and-forth movement. With this arrangement, the intermediate transport assembly 300 can only be moved to move the next group of sanitary napkin products W to the push position after the push head 430 has been pushed back to the pre-push position.

Fig. 8 is a schematic mechanism of the flipping assembly.

As shown in fig. 7 and 8, the flipping assembly 500 includes: 4 receptacles 510, rotating assembly 520, stop 530, push-in attachment plate 540, guide plate 550, and push-out attachment plate.

The rotating assembly 520 includes: a rotating frame 521 and a rotating motor 522. The rotating frame 521 is square, and the rotating motor 522 drives the rotating frame 521 to rotate by 90 degrees each time.

The container 510 is a rectangular parallelepiped having 6 faces and is sized to fit the contained sanitary napkin product W. The receptacle 510 is formed by an upper case, a lower case, a left case, and a right case, and has an open structure at front and rear opposite sides.

The 4 containers are respectively fixed on the extension lines of the four sides of the rotating frame to form an X shape and are evenly distributed on the circumference. For convenience of later explanation, the 4 containers 510 are container a, container B, container C, and container D, respectively.

A baffle 530 may be fixed to the integrated chassis 1000 and disposed at the rear side of the current position of the container a, mainly to prevent the sanitary napkin product W from sliding out of the container 510 due to inertia when the push-in pusher 430 pushes the sanitary napkin product W into the container.

The push-in connecting plate 540 is disposed at one side of the intermediate conveying assembly 300, and at the opposite side of the push-in pusher 430; the push-in connector 540 connects the intermediate transfer assembly 300 and the accommodator a.

The guide plates 550 are disposed at both sides of the push-in connection plate 540. One end of the guide plate 550 is adjacent to the opening of the position a receiver, matching the width of the receiver 510; the other end is adjacent to the intermediate conveyor assembly 300, the opening is greater than the width of the receptacle; serving as a guide for facilitating the sanitary napkin product W to be pushed into the container 510.

The push-out connection plate is arranged at one side of the output assembly 700 and at the opposite side of the push-out assembly 600; push out web connects output assembly 700 and receptacle 510; the same as the push-in connector structure and principle.

The main function of pushing in the connecting plate and pushing out the connecting plate is to prevent that the product drops in the gap between the devices, plays the effect that the removal is more smooth. The push-in connecting plate also provides a guide plate arrangement space.

Of course, it is possible to provide guide openings in the receptacles, with relatively small gaps between the devices, so that no push-in webs, guide plates and push-out webs are required.

As shown in fig. 1, the push-out assembly 600 has only a horizontal moving mechanism and a push-out head to push out the sanitary napkin product W from the container 510 of the inverting assembly 500. Because no product needs to be avoided, the pushing head only needs to do horizontal reciprocating motion, the structure and the working principle are the same as those of the pushing assembly 400, and the description is not repeated.

In this embodiment, the pushing assembly 400 and the pushing assembly 600 are disposed on the same side of the flipping assembly 500. Of course, the push-in assembly 400 and the push-out assembly 600 may be disposed at opposite sides of the turnover assembly 500 according to arrangement.

In this embodiment, the structure of the output module 700 is the same as that of the intermediate transfer module 300, and the description thereof will not be repeated. Of course, the structure of the output assembly 700 and the intermediate conveying assembly 300 can be implemented by different transmission methods, and are not limited to the method described in this embodiment.

The intermediate transport assembly 300 transports the sanitary napkin product W in the direction of the arrow to the front of the push-in pusher 430; the push-in pusher 430 pushes the sanitary napkin product W into the receptacle of the inverting assembly 500; the receptacle of the flipping module 500 is rotated to the front of the pushing head (hidden by the flipping module in the figure); the push-out pusher pushes the sanitary napkin product W from the container of the inverting assembly 500 onto the output assembly 700; the discharging assembly 700 transports the sanitary napkin product W to the next process.

As shown in fig. 1 and 2, the sheeting device 800 is disposed on the intermediate transport assembly 300, the sanitary napkin products fall onto the base plate 350, the product heights may be inconsistent, and the sheeting device 800 can flatten the sanitary napkin products W on the base plate 350.

The sheeting of the sheeting device 800 can move up and down to press down the sanitary napkin product. The pressing sheet of the pressing sheet device 800 may be inclined, the sanitary napkin product W enters the pressing sheet of the pressing sheet device 800 from a high position, the height of the sanitary napkin product W is pressed downward as the height of the pressing sheet is lower, and finally, the height of the sanitary napkin product W is uniform when coming out from the lowest position of the pressing sheet.

As shown in fig. 2, in the present embodiment, the counter 900 is a photoelectric sensor, and is disposed on one side of the input assembly 100, and is adjacent to the turntable device 200. The counter 900 counts the number of sanitary napkin products W entering the carousel apparatus 200. The chain 310 of the intermediate transport assembly 300 is moved according to the accumulated number of the counter 900, that is, the intermediate transport assembly 300 is not moved when the neutral position occurs, thus ensuring that the number of the sanitary napkin products W between each partition 340 is the same.

The working process of the sanitary towel stacker comprises the following steps:

the two belts of the input assembly clamp the sanitary towel products and convey the sanitary towel products to the embedded groove on the rotating disc of the rotating disc assembly.

After the two rotating disks rotate by 60 degrees, the products reach the middle conveying assembly, leave the rotating disks and enter the middle conveying assembly.

The intermediate transport assembly transports the sanitary napkin products to a push-in pusher position.

The push-in pushing head moves downwards first and then pushes the sanitary towel product forwards.

Under the action of the pushing head, the sanitary towel product enters the container A from the bell mouth of the guide plate through the pushing connecting plate.

The push-in pusher is upward and returns to the initial position downward while the input conveyor assembly transports the next group of products to the push-in pusher position.

At the same time, the container a rotates 90 degrees counterclockwise with the rotating frame, reaching the position of the container B.

The ejector pusher is moved forward to eject the sanitary napkin products from the receptacles past the ejector web to the output transport assembly.

The output conveying assembly conveys the overturned product to the next packaging device.

The container B is rotated through another 90 degrees to the position of the container C, then rotated through another rotation to the position of the container D, and finally returned to the position of the container a. In the secondary circulation process, 4 groups of products are turned over, and the production efficiency is greatly improved.
