Description

Transfer steering mechanism

Technical Field

The invention relates to the field of cookware production, in particular to a shifting and steering mechanism.

Background

As is well known, in a conventional pot production line, the production line is generally of a circulation type, and transfer and steering mechanisms for turning pots from a forward direction to a reverse direction are provided at both ends of the production line. In a general steering mechanism, the moving direction of the pot is directly guided to the tangential direction of the steering, but the linear velocity is not greatly reduced, so that the problem that the pot and the transfer mechanism rub or collide or fly out during the steering often occurs. Meanwhile, the existing steering mechanism also has the problem of overlarge occupied space.

The transfer steering mechanism at least has the following beneficial effects: the cookware is converted from the original semi-circular motion into the combined motion in the front-back direction and the left-right direction, so that the workpiece only moves linearly relative to the bearing disc during the motion, and the problem that the workpiece collides with the bearing disc due to the over-high linear speed and then flies out of the bearing disc can be avoided. The belt drive and the carrier plate move independently of one another, so that the speed can be adjusted better. Because the bearing plate only moves in a linear direction relative to the frame, the space required by the movement can be saved. When the workpiece moves on the belt transmission mechanism, the workpiece is contacted with the limit switch, so that the limit switch is started. After the limit switch is started, an electric signal is given to the first driving mechanism, so that the driving direction of the first driving mechanism is reversed, and the workpiece can return to a production line from the original path.

According to the transfer steering mechanism of the first aspect of the present invention, a transmission mechanism is provided between the first drive mechanism and the belt transmission mechanism; the belt transmission mechanism comprises at least two belt wheels and at least two conveying belts, and at least one belt wheel is connected with the transmission mechanism. The transmission mechanism can adjust the relative speed between the first driving mechanism and the belt transmission mechanism, so that the running speed of the belt transmission mechanism is not too fast or too slow. Meanwhile, the belt transmission mechanism can adjust the relative speed direction between the transmission mechanism and the first driving mechanism, so that the occupied area of the transmission mechanism and the first driving mechanism is reduced.

The movement of the slider on the guide rail will cause the carrier disc to move relative to said guide rail. The direction of the guide rail intersects the direction of the belt drive, so that the workpiece can be guided at a resultant speed.

The original semi-circular motion of the pot is converted into the combined motion in the front-back direction and the left-right direction, so that the workpiece only moves linearly relative to the bearing plate 20 during the motion, and the problem that the workpiece collides with the bearing plate 20 due to the excessively high linear speed and then flies out of the bearing plate 20 can be solved. The belt drive 30 and carrier tray 20 movements are independent of each other to better adjust the speed. Since the carrier plate 20 moves only in a linear direction with respect to the frame 10, the space required for the movement can be saved. The workpiece, as it moves on the belt drive 30, will contact the limit switch 25, thereby activating the limit switch 25. When the limit switch 25 is activated, an electric signal is applied to the first driving mechanism 47, so that the driving direction thereof is reversed, and the workpiece can be returned to the production line from the original path.

In some embodiments, referring to fig. 5, the workpiece to be processed is a pot. The production line of pan divide into and advances and retreat two, and two production line heads and tails communicate through two sets of shifting steering mechanisms respectively. The same end of both lines is located on the frame 10 and the carrier tray 20 is capable of movement between the ends of both lines. The direction of movement of the belt drive 30 is parallel to the direction of movement of the production line.

In some embodiments, the carrier tray 20 has a square structure, and except for the side communicating with the production line, the other three sides of the carrier tray 20 are provided with the baffles 22, and the baffles 22 are higher than the belt transmission mechanism 30.

The transmission mechanism 40 is capable of adjusting the relative speed between the first drive mechanism 47 and the belt transmission mechanism 30 so that the belt transmission mechanism 30 does not run too fast or too slow. At the same time, the belt transmission mechanism 30 can adjust the relative speed direction between the transmission mechanism 40 and the first drive mechanism 47, so that the area occupied by both is reduced.

In certain embodiments, referring to fig. 2 and 3, the drive mechanism 40 includes a drive sprocket 43, a driven sprocket 42, and a chain 41; the driving sprocket 43 is connected to a first driving mechanism 47, the driven sprocket 42 is coaxially interlocked with the pulley 31, and the size of the driving sprocket 43 is smaller than that of the driven sprocket 42. The transmission of the chain 41 has the advantages of accurate transmission ratio, reliable work and high efficiency. Since the driving sprocket 43 is connected to the first driving mechanism 47 and the driving sprocket 43 is smaller than the driven sprocket 42, the speed of the driven sprocket 42 is lower than that of the driving sprocket 43, i.e., the speed of the belt driving mechanism 30 is lower than that of the first driving mechanism 47, thereby preventing the speed of the belt driving mechanism 30 from being too fast to allow the moving speed of the workpiece to be too fast.
