In the conveying process of the workpieces, the initial placing posture and the stacking posture of part of the workpieces are inconsistent, and the part of the workpieces need to be overturned. For example, during the transport of the trays, the trays with the reverse side facing upwards need to be turned over to the trays with the front side facing upwards, so that the trays with the front side facing upwards can be stacked normally.

In the related art, a manipulator is generally used for grabbing a workpiece on a conveyor and overturning the workpiece, and then the overturned workpiece is put back into the conveyor. In addition, the manipulator is high in cost, complex in control and unfavorable for batch use.

Referring to fig. 1 and 2, the present utility model provides a flipping device comprising a transport module 400 and a flipping assembly.

The conveying module 400 is used for conveying the workpiece 700 before and after overturning.

The turnover assembly includes a rotatable shaft 200 and a turnover frame 300 coupled to the shaft 200, the turnover frame 300 being capable of receiving a work 700, the shaft 200 being driven by a rotation driving member 600.

It should be understood that the rotating shaft 200 can drive the roll-over stand 300 to rotate, so as to roll over the workpiece 700 on the conveying module 400 and put back on the conveying module 400.

It should be noted that, in the turning device according to the embodiment of the present utility model, the conveying module 400 includes, but is not limited to, a belt conveyor, a roller conveyor, and other conveying structures. The workpiece 700 may be, but is not limited to, a block-like or sheet-like structure such as a pallet, a plate, or the like. The workpiece 700 shown in fig. 1 is a tray.

It should be noted that, in the turning device according to the embodiment of the present utility model, the rotating shaft 200 may be connected to the output end of the rotation driving member 600, and the rotation driving member 600 may be a driving motor, etc., it is understood that the rotating shaft 200 is driven by the rotation driving member 600 to rotate around itself, so as to drive the turning frame 300 to perform a turning motion with respect to the conveying module 400. The roll-over stand 300 may be welded to the rotation shaft 200 to ensure stability of the roll-over stand 300 for a roll-over motion. Of course, the roll-over stand 300 may also be detachably connected to the rotating shaft 200, such as by a screw, a buckle, or the like, to be connected to the rotating shaft 200, so as to facilitate the disassembly and replacement of the roll-over stand 300, so that the roll-over stand 300 can adapt to workpieces 700 with different specifications and shapes, and overall adaptability of the roll-over apparatus is improved.

It can be appreciated that when the turnover device of the embodiment of the utility model is used, the turnover frame 300 receives the workpiece 700 conveyed by the conveying module 400, and the rotating shaft 200 drives the turnover frame 300 to rotate 180 degrees, so that the workpiece 700 is turned back to the conveying module 400, and the conveying module 400 continuously conveys the turned workpiece 700, so that the function of automatically turning the workpiece 700 in the conveying process of the workpiece 700 is realized, and the conveying continuity of the workpiece 700 is ensured.

It should be understood that, by arranging the rotating shaft 200 and the turning frame 300 connected to the rotating shaft 200, the turning device in the embodiment of the utility model makes the conveying action of the conveying module 400 on the workpiece 700 and the turning action of the turning frame 300 on the workpiece 700 mutually independent, avoids the interference of the conveying module 400 when the turning frame 300 turns the workpiece 700, and improves the stability of turning the workpiece 700.

Meanwhile, compared with the traditional manipulator, the overturning frame 300 can effectively save the occupied space, is lower in cost, simplifies the control procedure of overturning the workpiece 700 in the conveying process and continuously conveying the overturned workpiece 700, ensures the conveying continuity of the workpiece 700, and is beneficial to using the overturning assemblies in a logistics conveying system in batches.

Referring again to fig. 1 and 2, in some embodiments of the present utility model, the roll-over stand 300 is provided with a limit groove 310 for the workpiece 700 to enter or exit from the roll-over stand 300.

Specifically, referring to fig. 1, the conveying module 400 is a chain machine that conveys the work 700 in a left-to-right direction.

When the conveying module 400 drives the workpiece 700 thereon to be conveyed from left to right, the roll-over stand 300 is rotated, so that the notch of the limiting groove 310 faces the workpiece 700 on the conveying module 400, and the workpiece 700 is driven by the conveying module 400 to enter the limiting groove 310 on the roll-over stand 300 from the notch of the limiting groove 310, and is carried by the limiting groove 310. Then, the rotating shaft 200 drives the roll-over stand 300 to rotate 180 ° relative to the conveying module 400, thereby turning over the workpiece 700 on the roll-over stand 300. It should be understood that after the roll-over stand 300 is turned 180 °, the notch of the limiting groove 310 is turned from left to right, and the workpiece 700 in the limiting groove 310 is placed on the conveying module 400, so that the workpiece 700 in the limiting groove 310 is separated from the limiting groove 310 from left to right under the driving of the conveying module 400 and is continuously conveyed from left to right under the driving of the conveying module 400.

It is to be understood that, by arranging the limiting groove 310 on the roll-over stand 300, and making the notch of the limiting groove 310 be in the conveying path of the conveying module 400, the roll-over stand 300 can directly butt-joint and bear the workpiece 700 on the conveying module 400, and the limiting groove 310 limits the workpiece 700 vertically, so that the stability of the workpiece 700 in the roll-over process is ensured, and the workpiece 700 is prevented from being separated from the roll-over stand 300.

Moreover, the above arrangement does not need to provide an additional power handling member to clamp and handle the workpiece 700 on the conveying module 400 to the roll-over stand 300 or to clamp and handle the workpiece 700 from the roll-over stand 300 to the conveying module 400, so that the arrangement cost of related equipment is reduced, the continuity of conveying the workpiece 700 is effectively ensured, and the efficiency of turning and conveying the workpiece 700 is improved.

Further, referring again to fig. 1 and 2, opposite sides of the limiting groove 310 penetrate, so that the limiting groove 310 is suitable for workpieces 700 of different sizes, and two sides of the limiting groove 310 can be extended from two sides of the workpiece 700.

It should be noted that, referring to fig. 1, opposite sides of the limiting slot 310 are front and rear ends of the limiting slot 310 (the front and rear directions are marked in fig. 1). Correspondingly, the two sides of the workpiece 700 are the front and rear ends of the workpiece 700. The width of the stopper groove 310 refers to the length of the stopper groove 310 in the front-rear direction, and the width of the work 700 corresponds to the length of the work 700 in the front-rear direction.

When the conveying module 400 (such as a chain machine) conveys the workpiece 700, the workpiece 700 is always attached to the conveying surface of the conveying module 400. When the work 700 enters the limit groove 310 of the roll-over stand 300, both sides of the work 700 protrude out of both sides of the limit groove 310 and are put on the chain of the chain machine, respectively. So set up for the roll-over stand 300 is with work piece 700 upset 180 back, and the relative both sides of work piece 700 still can be put on the transport face of transport module 400, thereby makes transport module 400 can directly drive the work piece 700 that obtains the upset, and then breaks away from out from the spacing groove 310 of roll-over stand 300, so, improves the continuity to work piece 700 carries by a wide margin, improves the conveying efficiency to work piece 700.

It should be understood that, the two opposite sides of the limiting groove 310 penetrate through, so that the two sides of the workpiece 700 extend out and are placed on the conveying module 400, so that the workpiece 700 carried on the roll-over stand 300 is always on the conveying surface of the conveying module 400 before and after being turned over, thereby ensuring that the conveying module 400 can directly drive and convey the turned workpiece 700, and further improving the conveying continuity of the workpiece 700.

In some embodiments of the present utility model, referring to fig. 1 and 2, the roll-over stand 300 includes a first limiting plate 320, a second limiting plate 330, and a stop plate 340 connected between the first limiting plate 320 and the second limiting plate 330, the first limiting plate 320 being spaced apart from the second limiting plate 330, the first limiting plate 320, the second limiting plate 330, and the stop plate 340 defining a limiting slot 310. For the installation of being convenient for, still perpendicular fixed mounting panel 350 between first limiting plate 320 and the second limiting plate 330, mounting panel 350 and backstop board 340 parallel interval arrangement, mounting panel 350 can be through the fixed continuous of pivot 200 of mode of screwed connection, for the installation of being convenient for with dismantle the screw, can set up in the middle of the backstop board 340 and dodge the hole, the operator can pass and dodge the hole installation and dismantle the screw.

Specifically, the first limiting plate 320, the second limiting plate 330 and the stop plate 340 enclose a U-shaped limiting groove 310, and the stop plate 340 serves as a groove bottom of the U-shaped limiting groove 310, so that not only can the workpiece 700 be blocked and limited, but also the strength of the whole roll-over stand 300 can be enhanced as a reinforcing plate.

It should be understood that, when the workpiece 700 on the conveying module 400 is received, the first limiting plate 320 and the second limiting plate 330 play a role in limiting the workpiece 700 up and down, and the stop plate 340 plays a role in limiting the workpiece 700 in the horizontal direction, so as to avoid the workpiece 700 from sliding horizontally after entering the limiting groove 310.

In some embodiments, the workpiece 700 has a receptacle 710 formed therein, and when the roll-over stand 300 receives the workpiece 700, the workpiece 700 is disposed between the first limiting plate 320 and the second limiting plate 330, or one of the first limiting plate 320 and the second limiting plate 330 is inserted into the receptacle 710.

Specifically, as one embodiment, the conveying module 400 includes two parallel narrow conveying belts or conveying chains disposed at intervals, and the two narrow conveying belts or conveying chains move at equal heights and synchronously. The upper surfaces of the two narrow conveyor belts or conveyor chains form the conveying surface for conveying the workpiece 700. An avoidance cavity 410 for the first limiting plate 320 to move is formed between the two narrow conveying belts or conveying chains. By arranging the conveying module 400 into two synchronous conveying belts or conveying chains, and enabling the two conveying belts or conveying chains to form the avoidance cavity 410, the first limiting plate 320 of the roll-over stand 300 can be rotated into the avoidance cavity 410, and during installation, the installation height of the turnover assembly can be designed, so that the turnover assembly can be turned to the state that the first limiting plate 320 is flush with the conveying surface of the conveying module 400 or lower than the conveying surface of the conveying module 400, and the whole workpiece 700 enters between the first limiting plate 320 and the second limiting plate 330; the installation height of the turnover assembly can be designed, so that the turnover assembly can be turned over to the position where the first limiting plate 320 is higher than the conveying surface of the conveying module 400, and the first limiting plate 320 can be inserted into the insertion hole 710 of the workpiece 700.

Of course, in other embodiments, the conveying surface of the conveying module 400 is a single wide conveying belt, and the overturning assembly is mounted above the single wide conveying belt, so that the overturning assembly can be overturned to the first limiting plate 320 to be inserted into the insertion hole 710 of the workpiece 700 by designing the mounting height of the overturning assembly.

In addition, in other embodiments, the workpiece 700 is a tray, in which two insertion holes 710 are disposed at intervals, the first limiting plate 320 includes two first pins 321 disposed at intervals, and the second limiting plate 330 includes two second pins 331 disposed at intervals.

Specifically, the workpiece 700 is a chinese character 'chuan' shaped tray, and two through fork openings on the chinese character 'chuan' shaped tray are the insertion holes 710. The two first pins 321 are two parallel and plate-coplanar plugboards, and the two second pins 331 are also two parallel and plate-coplanar plugboards.

It should be understood that, when the conveying module 400 conveys the workpiece 700 to the position of the roll-over stand 300, the two insertion holes 710 on the workpiece 700 respectively penetrate into the two first pins 321 of the first limiting plate 320, and meanwhile, the upper end of the workpiece 700 is limited below the second limiting plate 330, so that stable bearing of the workpiece 700 can be realized. Moreover, the two first pins 321 of the first limiting plate 320 are matched with the two insertion holes 710 of the workpiece 700 in a penetrating manner, so that stability of the workpiece 700 in the overturning process can be improved, the workpiece 700 is prevented from swinging or falling to one side in the overturning process, and safety of the overturning frame 300 in overturning is further ensured.

It should be understood that, when the roll-over stand 300 is turned 180 ° from the initial position, the second limiting plate 330 is located below the first limiting plate 320, and the notch of the limiting groove 310 faces to the right. At this time, if the conveying module 400 conveys the workpiece 700 from right to left, the two insertion holes 710 on the workpiece 700 respectively penetrate into the two second pins 331 of the second limiting plate 330.

It can be appreciated that the shapes and structures of the first limiting plate 320 and the second limiting plate 330 are the same, so that the turnover frame 300 can still bear and turn over the workpiece 700 when the conveying direction of the conveying module 400 is changed, so that the whole turnover device can adapt to the conveying modules 400 with different conveying directions, and adaptability and consistency are improved.

In some embodiments of the present utility model, referring again to fig. 1, the conveyor module 400 includes a first conveyor 420 and a second conveyor 430 disposed at intervals, the first conveyor 420 being configured to convey the workpiece 700 before flipping, and the second conveyor 430 being configured to convey the workpiece 700 after flipping.

It is understood that the first conveyor 420 and the second conveyor 430 are two separate conveyors, which are disposed at equal heights. After the first conveyor 420 conveys the workpiece 700 into the roll-over stand 300, the first conveyor 420 may be shut down, reducing frictional losses between the workpiece 700 and the first conveyor 420. Meanwhile, the normal operation state of the second conveyor 430 is maintained, so that the second conveyor 430 can directly convey the workpiece 700 on the roll-over stand 300 to the right after the roll-over stand 300 rolls over the workpiece 400 by 180 °, thereby improving the continuity of conveying the workpiece 700.

In some embodiments, the frame 100 of the conveying module 400 is provided with a first positioning member (not shown in the figure) and a second positioning member (not shown in the figure), the roll-over stand 300 has a first position state and a second position state, when the roll-over stand 300 is in the first position state, the roll-over stand 300 is abutted against the first positioning member, and when the roll-over stand 300 is in the second position state, the roll-over stand 300 is abutted against the second positioning member.

The first position state of the roll-over stand 300 refers to a horizontal state of the roll-over stand 300 before the roll-over operation, in which the roll-over stand 300 abuts against the first in-place member and is kept parallel to the conveying module 400; the second position of the roll-over stand 300 is a horizontal state of the roll-over stand 300 rotated 180 ° relative to the first position, and the roll-over stand 300 is abutted against the second positioning member, and is also kept parallel to the conveying module 400.

In particular, the first and second nest members may each be configured to rest against a nest plate of the roll-over stand to ensure stability of the roll-over stand 300 in the first and second position states.

In addition, the first and second in-place members may be provided with first and second contact sensors, respectively, which are electrically connected with the rotation driving member 600 to detect whether the roll-over stand 300 is in the first and second position states, respectively, so that the detection signals are fed back to the rotation driving member 600 to control the rotation angle of the rotation driving member 600, thereby improving the accuracy of the rotation shaft 200 and the rotation angle of the roll-over stand 300 on the rotation shaft 200.

In some embodiments of the present utility model, referring again to fig. 1 and 2, two bearing seats 500 are further provided on the frame 100, and two ends of the rotating shaft 200 are respectively mounted on the bearing seats 500 through bearings. It should be noted that, the bearing and the bearing seat 500 are integrated, and the arrangement of the bearing seat 500 facilitates the installation, disassembly and replacement of the rotating shaft 200.

Furthermore, in some embodiments of the utility model, the entire flipping assembly can be raised and lowered relative to the transport module 400. As in one embodiment, the frame 100 is provided with a lifting seat (not shown), the rotating shaft 200 is rotatably installed on the lifting seat, and the roll-over stand 300 is fixedly connected with the rotating shaft 200.

It should be noted that, when the workpiece 700 does not need to be turned over, the lifting seat drives the turning frame 300 to descend so as to be hidden under the conveying surface of the conveying module 400. When the workpiece 700 needs to be overturned, the lifting seat drives the overturning frame 300 to ascend, so that the overturning frame 300 is reset to the initial value to-be-overturned position, and at the moment, the avoidance cavity 410 arranged on the conveying module 400 provides a lifting movement space for the rotating shaft 200 and the whole overturning frame 300, so that the conveying module 400 is prevented from interfering the lifting of the rotating shaft 200 and the overturning frame 300.

It is to be understood that the turnover assembly can be hidden below the conveying module 400 or reset to the initial value to be turned over according to the actual turnover requirement on the workpiece 700 by the function of relatively lifting the conveying module 400, so that the applicability of the turnover device to different use environments is improved.

In addition, the embodiment of the utility model also provides conveying equipment, which comprises the overturning device.

It should be understood that, since the above-mentioned turning device is configured in the conveying apparatus of the present utility model, the conveying apparatus also has the same technical effects brought by the above-mentioned turning device, that is, the conveying action of the conveying module 400 on the workpiece 700 and the turning action of the turning frame 300 on the workpiece 700 are independent from each other, so that the turning frame 300 is prevented from being interfered by the conveying module 400 when the workpiece 700 is turned, and the stability of turning the workpiece 700 is improved. Meanwhile, compared with the traditional manipulator, the overturning frame 300 can effectively save the occupied space, is lower in cost, simplifies the control procedure of overturning the workpiece 700 in the conveying process and continuously conveying the overturned workpiece 700, ensures the conveying continuity of the workpiece 700, and is beneficial to using the overturning assemblies in a logistics conveying system in batches.

As one of the embodiments, the transport device can also be used as a destacking device for pallets. In the process of transferring the trays, in order to reduce the occupied space of the trays, the front and back sides of the trays are generally stacked alternately so as to offset the stacking height occupied by the trays, thereby improving the tray loading rate. When the tray is needed, the stacked tray group needs to be unstacked and the tray with the reverse side upwards is turned over and aligned.

Specifically, the workpiece 700 in the turnover device is a tray, and a destacking station is arranged on a conveying path of the conveying module 400;

the conveying apparatus further includes:

the first unstacking mechanism 800 comprises a first lifting seat 810 capable of lifting and a first telescopic member 820 mounted on the first lifting seat 810, wherein the first telescopic member 820 is configured to be capable of forking a tray at an unstacking station;

the second unstacking mechanism 900 includes a second lifting base 910 capable of lifting and a second telescopic member 920 mounted on the second lifting base 910;

the conveyor line 1000, the second telescoping member 920 is configured to transfer trays between the destacking station and the conveyor line 1000.

Further, a first stacking station is arranged on the conveying module 400, a first stacking device 1100 for stacking trays is arranged at the first stacking station, and the turning device is located between the first stacking device 1100 and the unstacking station.

Further, a second stacking station is disposed on the conveying line 1000, and a second stacking device 1200 for stacking trays is disposed at the second stacking station.

The specific method for unstacking by using the conveying equipment is as follows:

the group of trays to be destacked is placed at the destacking station, and the first destacking mechanism 800 lifts the trays of the penultimate layer and above in the group of trays to be destacked a certain distance so that the destacking station only retains the trays of the penultimate layer in the group of trays to be destacked.

Then, the second unstacking mechanism 900 takes out the front tray in the last-last tray layer and conveys the front tray to the conveying line 1000, and the conveying line 1000 conveys the front tray in the first direction X1 in fig. 3.
