The technical solution of the present invention is further explained by the following embodiments with reference to the drawings.

As shown in fig. 1, the present embodiment discloses a conveying line, which specifically includes a frame 10 and a conveying mechanism 20, wherein the conveying mechanism 20 is mounted on the frame 10 and can transfer goods to a specific position. Goods are generally deposited and are transported in the material frame to improve the transportation efficiency of transfer chain, transport mechanism 20 is used for the bearing and transports the material frame.

For convenience of description, the present embodiment is described by taking a roller conveyor line as an example. The frame 10 includes a bottom plate 101 and side plates 102, the length direction of the bottom plate 101 is the transfer direction of the material frame, and the side plates 102 are respectively arranged on the two sides of the upper end of the bottom plate 101 along the width direction thereof to enclose the transfer passage of the material frame. The conveying mechanism 20 adopts a roller conveying manner, and the plurality of rollers are divided into two rows of roller groups, and the two rows of roller groups are arranged on the bottom plate 101 side by side and are respectively positioned at the inner sides of the corresponding side plates 102 so as to jointly support the material frame. The roller conveying line further comprises a roller driving motor, and the roller driving motor drives the two rows of roller groups to synchronously rotate through the chain conveying mechanism so as to drive the material frame to move along the transfer direction of the material frame. As the chain conveying mechanism and the roller conveying mode are conventional technical means in the field of conveying lines, the specific structure and the working principle of the chain conveying mechanism and the roller conveying mode are not described again.

It should be noted that the material frame of this embodiment is a square material frame, and has two short sides oppositely disposed along the length direction thereof and two long sides oppositely disposed along the width direction thereof. When the conveying line works, the two long side edges of the material frame are respectively positioned above the two rows of roller groups or the two short side edges of the material frame are respectively positioned above the two rows of roller groups. Of course, the material frame may also be a disc structure or a rectangular structure, etc., and is not limited in particular.

As shown in fig. 1, in order to prevent the position deviation of the roller set during the transportation of the material frame, the conveyor line further includes guide plates 60, the guide plates 60 extend along the transportation direction of the material frame, two guide plates 60 are respectively adjacently disposed on the outer side of the corresponding conveying mechanism 20 and are higher than the top end of the conveying mechanism 20, and the opposite side surfaces of the two guide plates 60 can respectively abut against the corresponding short side of the material frame.

Specifically, the guide plates 60 are fixedly mounted to the upper ends of the two side plates 102, respectively, to increase the height of the guide plates 60. It should be noted that the distance between the two guide plates 60 is substantially equal to the length of the material frame. When two short sides of material frame are located the top of two rows of cylinder groups respectively, and when the drive of cylinder was followed the direction of transfer and was removed, two short sides of material frame respectively with two deflector 60 looks butt to play direction limiting displacement to the removal process of material frame along the direction of transfer, avoid the material frame to take place the offset, play the effect of preventing the off tracking.

Similarly, when two long sides of the material frame are respectively located above two rows of roller sets and move along the transfer direction under the driving of the rollers, in order to prevent the material frame from shifting on the roller sets, the conveying line further comprises a guide wheel set 70 and a guide driving member, and the two guide wheel sets 70 are respectively arranged below the corresponding conveying mechanism 20. The guiding driving member is disposed on the frame 10, and the guiding driving member drives the guiding wheel sets 70 to rise and protrude from the top end of the conveying mechanism 20, so that the guiding wheels of the two guiding wheel sets 70 can abut against the corresponding long sides of the material frame respectively.

Specifically, the guide wheel group 70 includes a plurality of guide wheels spaced apart from each other on the bottom plate 101, and one guide wheel is disposed between each roller, so that the rollers and the guide wheels are distributed in a staggered manner. The guide wheels are mounted on the base plate 101 in such a way that their axial directions are parallel to the vertical direction and are rotatable. The pitch of the two rows of guide wheel sets 70 is substantially equal to the width of the material frame so that the guide wheels of the two rows of guide wheel sets 70 can abut against the two long sides of the material frame, respectively, and the guide limiting function is achieved. The guide driving piece is a guide cylinder, so that the guide driving piece is convenient to disassemble and assemble and convenient to maintain. The guide cylinder is fixedly arranged below the bottom plate 101, and a piston rod of the guide cylinder is in transmission connection with the guide wheel set 70 so as to realize the lifting of the guide wheel set 70.

When two short sides of the material frame are respectively positioned above two rows of roller groups, the height of the guide wheel is lower than that of the rollers, so that the normal transfer function of the roller groups is prevented from being influenced. When the two long sides of the material frame are respectively positioned above the two rows of roller groups, the two rows of guide wheel groups 70 are driven by the guide air cylinders to be lifted, so that the guide wheels of the two rows of guide wheel groups 70 are respectively abutted against the two long sides of the material frame, and the material frame is prevented from being shifted on the roller groups.

In the process of transferring the material frame, rotation reversing is sometimes needed to change the transferring direction or posture of the material frame. Therefore, the conveying line also comprises a reversing and circulating mechanism which is positioned between the conveying mechanisms 20 and used for reversing the rotation of the material frames. Therefore, a reversing and circulating mechanism is generally arranged in the existing conveying line, and the rotation reversing of the material frame is realized through the reversing and circulating mechanism.
