As shown in fig. 1, the rod transferring apparatus includes a frame 10, a gripper mechanism 20, a swing mechanism 30, a transfer mechanism 40, and a push rod mechanism 50. The housing 10 is generally frame-shaped for supporting other mechanisms or components. After the gripper mechanism 20 grips the rod piece 60, the swing mechanism 30 drives the gripper mechanism 20 to move to the target position and then releases the rod piece 60 to the conveying mechanism 40, after the conveying mechanism 40 conveys the rod piece 60 to the target position, the rod piece 60 is pushed out of the conveying mechanism 40 through the push rod mechanism 50, and the transfer of the rod piece 60 is completed. In the present application, the rod 60 may be solid or hollow.

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

One end of the swing cylinder 31 is hinged to the frame 10, and the other end 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 stretches and contracts.

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

Fig. 5 is a schematic structural view of the conveying 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, a pair of transfer wheels 41 are sprockets, and are rotatably connected to both end portions of the frame 10. The conveying chain 42 is a chain, bypasses the pair of conveying wheels 41, and is used for driving the pair of conveying wheels 41 to synchronously rotate.

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 is penetrated at both ends, and is provided at the bottom with a coupling hole for coupling to the conveyor chain 42 by a coupling member. After the gripper 22 releases the rod 60, the rod 60 falls into the bracket 43 from the opening at the top of the bracket 43 to hold the rod 60. In some preferred embodiments, the top of the bracket 43 is provided with a guide portion 431, and the guide portion 431 is inclined relatively outwards to guide the rod 60 into the bracket 43, so that the rod 60 enters the opening of the top of the bracket 43 under the guide of the guide portion 431.

The pushing frame 54 includes two pushing rods 541 and a connecting portion 542, where the pushing rods 541 are respectively connected with the connecting portion 542 to form a "U" structure, and one ends of the two pushing rods 541 pass through the through holes of the sliding seat 53 and are connected to the pushing plate 52 and the output shaft of the pushing 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 being excessively large in stroke, and the push rod cylinder 51 is stopped by being abutted by the connection portion 542 of the push frame 54 when the stroke exceeds a preset value. The push plate 52 has a generally flat plate-like structure with a plurality of downwardly extending push prongs 521 at the ends thereof. The width of the push fork 521 is smaller 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. In this way, the push fork 521 is 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 is pushed out of the bracket 43.

A rod transferring method for transferring the rod 60 using the rod transferring apparatus according to the above embodiment will be described in detail.

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

First, when the swing cylinder 31 is extended, 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 to above the lever 60 around an arc with the swing link 32 as a radius;

Then, the gripper 22 of the gripper mechanism 20 grips the rod 60, and at this time, the rod 60 is gripped by the gripper 22 and can move following the gripper 22.

Then, the swing cylinder 31 is contracted, and the swing link 32 is driven to swing so that the gripper mechanism 20 moves to the second position following the swing link 32. At this time, the gripper 22 moves above the bracket 43 of the transfer mechanism 40 following the swing lever 32.

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-described steps accomplish the purpose of transferring the lever 60 from the home position to the transfer mechanism 40. In some embodiments, the rod transfer method may further include the following steps.

After the rod 60 falls into the carriage 43 of the transfer mechanism 40, the pair of transfer wheels 41 of the transfer mechanism 40 drive the carriage 43 to move through the transfer chain 42 to transfer the rod 60 until the rod 60 follows the carriage 43 to the 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 member 60 out of the bracket 43, thereby realizing the transfer function of the rod member 60.

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