Fig. 1 is a schematic structural view of a bar transferring apparatus. As shown in fig. 1, the bar transfer apparatus includes a frame 10, a gripper mechanism 20, a swing mechanism 30, a transfer mechanism 40, and a push rod mechanism 50. The frame 10 is generally frame-shaped and is used to support other mechanisms or components. After the gripper mechanism 20 grips the rod 60, the swing mechanism 30 drives the gripper mechanism 20 to move to the target position and then releases the rod 60 to the transfer mechanism 40, and after the transfer mechanism 40 transfers the rod 60 to the target position, the rod 60 is pushed out of the transfer mechanism 40 through the push rod mechanism 50, and the transfer of the rod 60 is completed. In the present application, the rod 60 may be a solid or hollow tube.

Fig. 2 is a schematic view of the gripper mechanism 20 of the bar transfer apparatus. As shown in fig. 2, the gripper mechanism 20 includes a gripper base 21 and a gripper 22. In this embodiment, the gripper seat 21 is substantially an N-shaped frame structure, and the number of the grippers 22 is two, and the two grippers extend in the vertical direction, and the end (top end) of the gripper seat 21 connected thereto is hinged to the gripper seat 21. The bottom end of the gripper 22 is provided with opposite open slots and is connected with a driving cylinder, which is driven to grip open or close to grip the rod 60 or release the rod 60.

Fig. 3 is a schematic structural view of the swing mechanism 30 of the bar transferring apparatus. As shown in fig. 3, the swing mechanism 30 includes a swing lever 32, a swing cylinder 31, and a lift cylinder 33. In the present embodiment, the number of the swing links 32 is two, and the two swing links are arranged in parallel to each other in the vertical direction. The bottom end of the swing rod 32 is hinged to the frame 10, and the top end is hinged to the bottom of the claw seat 21. One end of the swing cylinder 31 is hinged to the frame 10, and the other end of the swing cylinder 31 is hinged to the middle of the swing rod 32, so that the swing rod 32 can be driven to swing back and forth when the swing cylinder 31 extends and retracts.

Fig. 4 is a schematic structural diagram of the jacking cylinder 33 and the swing link 32. As shown in fig. 4, the jacking cylinder 33 is disposed substantially in a vertical direction, one end of the jacking cylinder is connected to the frame 10, and the other end of the jacking cylinder is hinged to the jacking block 321. The jacking block 321 is connected to the side wall of the swing rod 32, and the side surface facing the jacking cylinder 33 is an inclined surface, and is used for jacking the swing rod 32 when the swing rod 32 swings, so that the acceptance balance of the swing rod 32 is improved.

Fig. 5 is a schematic structural view of the transfer mechanism 40. As shown in fig. 5, the conveying mechanism 40 includes a pair of conveying wheels 41, a conveying chain 42, and a plurality of brackets 43. In the present embodiment, the pair of conveying wheels 41 are sprockets and are rotatably connected to both ends of the frame 10. The transmission chain 42 is a chain and bypasses the pair of transmission wheels 41 to drive the pair of transmission wheels 41 to rotate synchronously.

Fig. 6 is a schematic structural view of the bracket 43. As shown in fig. 6, the bracket 43 is open at the top and has both ends penetrating, and has a coupling hole at the bottom for coupling to the conveyor chain 42 through a coupling member. After the gripper 22 releases the lever 60, the lever 60 drops from the opening at the top of the bracket 43 into the bracket 43 to hold the lever 60. In some preferred embodiments, the top of the bracket 43 is provided with a guide portion 431, and the guide portion 431 is relatively inclined outward to guide the rod 60 into the bracket 43, so that the rod 60 enters the opening at the top of the bracket 43 under the guidance of the guide portion 431.

Fig. 7 is a schematic structural view of the pusher mechanism 50. As shown in fig. 7, the push rod mechanism 50 includes a push rod cylinder 51, a push frame 54, a slide 53, and a push plate 52. The slider 53 is fixed to the frame 10 and has three through holes penetrating in the horizontal direction. The push rod cylinder 51 is fixedly connected to the slide 53, and an output shaft of the push rod cylinder 51 protrudes from a through hole of the slide 53 and is connected to the push plate 52. The push frame 54 comprises two push rods 541 and a connecting part 542, the push rods 541 are respectively connected with the connecting part 542 to form a U-shaped structure, and one ends of the two push rods 541 penetrate through the through holes of the sliding seat 53 and are connected with the push plate 52 and the output shaft of the push rod cylinder 51. The push rod cylinder 51 is located between the push rods 541, so that the push rod cylinder 51 can be prevented from having an excessively large stroke, and the push rod cylinder 51 is abutted by the connecting portion 542 of the push frame 54 and stopped when the stroke exceeds a preset value. The push plate 52 has a substantially flat plate-like structure, and a plurality of push forks 521 extending downward are provided at the end thereof. The width of the push fork 521 is less than or equal to the inner diameter of the push frame 54, and the push plate 52 is connected to the output shaft of the push rod cylinder 51. Thus, the push fork 521 can be pushed to move back and forth along the length direction of the bracket 43 by the driving of the push rod cylinder 51, so that the rod 60 can be pushed out of the bracket 43.

A bar transferring method for effecting the transfer of the bars 60 by means of the bar transferring apparatus according to the above-described embodiment will be described in detail.

In the present embodiment, the bar 60 is placed at the home position, and the automatic transfer of the bar 60 to the target position is achieved by the bar transfer apparatus.

First, when the swing cylinder 31 extends, the swing link 32 is driven to swing, so that the gripper mechanism 20 moves to the first position following the swing link 32. At this time, the gripper 22 of the gripper mechanism 20 moves above the lever 60 around an arc with the swing link 32 as a radius;

the gripper 22 of the gripper mechanism 20 then grips the rod 60, at which point the rod 60 is gripped by the gripper 22 and can follow the movement of the gripper 22.

Then, the swing cylinder 31 contracts, and drives the swing link 32 to swing, so that the gripper mechanism 20 moves to the second position along with the swing link 32. At this time, the gripper 22 follows the swing link 32 to move above the carriage 43 of the transfer mechanism 40.

Then, the gripper 22 of the gripper mechanism 20 releases the lever 60 so that the lever 60 falls into the carriage 43 of the transfer mechanism 40 to transfer the lever 60.

The above steps accomplish the purpose of transferring the bar 60 from the home position to the transfer mechanism 40. In some embodiments, the stem transfer method may further include the following steps.

After the bar member 60 falls into the carriage 43 of the transfer mechanism 40, a pair of transfer wheels 41 of the transfer mechanism 40 moves the carriage 43 by a transfer chain 42 to transfer the bar member 60 until the bar member 60 follows the carriage 43 to a target position.

Then, the push rod cylinder 51 of the push rod mechanism 50 drives the push plate 52 to move along the length direction of the bracket 43 so as to push the rod 60 out of the bracket 43, thereby realizing the transfer function of the rod 60.

In the above rod piece transferring device, the swing cylinder 31 pushes the swing rod 32 to enable the gripper mechanism 20 to move to an initial position along with the swing rod 32, the gripper 22 grips the rod piece 60, and when the swing cylinder 31 pulls back the swing rod 32 to enable the gripper mechanism 20 to move to a target position along with the swing rod 32, the gripper 22 releases the rod piece 60, so that the rod piece 60 can be automatically transferred, and the production and processing efficiency of the rod piece 60 is effectively improved.
