Description

[Detailed description of the invention] Industrial applications The present invention is suitable for pick-and-operate orders that require a turning function. This relates to a press transfer device.

BACKGROUND TECHNOLOGY φ In recent years, pick-and-presses having a turning function have been configured to perform vertical movement, back-and-forth movement, and turning movement using individual drive systems.

An example of the above-mentioned conventional transfer device with a turning function will be described below with reference to FIG. In Figure 4, 1
3 is a transfer head section, 14 is a slide block section for moving the transfer head section 13 back and forth, 16 is a bushing rod, 1
Reference numeral 6 denotes a lever that connects the slide block portion 14 and the bushing rod 16 and rotates about point 0 as a fulcrum; 17 refers to a bushing rod that holds the bushing rod 15 slidably up and down and moves the slide block portion 14 up and down; 18;
is a housing part that holds the bushing rod 17 so as to be able to slide up and down and to rotate around the axis of the bushing rod 17. The vertical movement, back and forth movement, and rotational movement of the transfer head part 13 are controlled individually. It consisted of a drive system.

Problems to be Solved by the Invention However, with such conventional devices, individual drives are required for forward and backward movement and turning movement, and the device is complicated, making it difficult to route the drive source.

Therefore, the present invention simplifies the routing design of the drive source by performing the back-and-forth movement and turning movement with the same drive.

Means for Solving the Problems In order to achieve the above object, the present invention provides a swing lever that is movable and pivotable in the front and back direction, a cam 7 lower provided at one end of the swing lever, and other parts of the swing lever. A transfer head provided at the end, and a U that contacts the cam follower and the cam follower fits into the center of the contact side.
A temporary cam having a letter-shaped groove to control the rotational posture of the swing lever is always in contact with the lower of the cam 7, and the tension spring and the swing lever are set at the center of rotation. (2) It is equipped with a drive means for moving it in the rear direction.

For production The effect of this technical means is as follows.

In other words, as the swing lever is moved in the front-back direction, the swing lever and the cam follower provided at one end of the swing lever move into the plate cam when the transfer head moves in the front-back direction. The rotational attitude is controlled by contacting the At this time, in the U-shaped groove provided at the center of the contact side of the plate cam, the pivot lever rotates in a direction in which the lower of the cam 7 fits into the U-shaped groove, and the transfer head section pivots.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to the accompanying drawings. In FIGS. 1 and 2, 1B is a swing lever in which the chuck 2 and cam follower 3 are arranged in opposite positions relative to the rotational fulcrum 0; 4 is a plate cam having a U-shaped groove e in the center; 5 6 is a tension spring that acts to keep the cam follower 3 and the plate cam 4 in constant contact; 6 is a head housing that holds the swing lever 1 in a rotatable manner; and 7 is a tension spring that allows the head housing 6 to slide in the directions of arrows a and b (Fig. 2). a slide bearing that is movably held; 8 is a plate that connects the head housing 6 and the slide bearing 7; 9rfi arrow c;
A slide bearing held slidably in the d direction (FIG. 1), 10 a plate that connects the slide bearing 7 and the slide bearing 9 and has the plate cam 4 fixed to its upper end, and 11 a bracket that holds the slide bearing 9. , 12 is a connecting rod connected to the plate 8 and driven in the directions of arrows a and b, and 13 is a connecting rod that drives the plate 8 in the directions of arrows c and d.

The operation of the rotating transfer device constructed as described above will be explained with reference to FIGS. 1 to 3.

When the connecting rod 12 is moved in the direction of arrow a, the swing lever 1 has a cam follower 3 that rolls along a plate cam 4 having a U-shaped groove e in the center, and the cam follower 3 fits into the U-shaped groove e. Then, the chuck 2 makes a turning movement in the direction of the arrow f around the rotation fulcrum O, and moves forward in the direction of the arrow while changing the posture of the chuck 2 as shown in FIG. 3 (5) to p, and makes a turning movement in the direction of the arrow f. It is supposed to be done.

As described above, according to this embodiment, there is a swing lever 1 that is movable and pivotable in the front-rear direction, a cam follower 3 provided at one end of the swing lever 1, and a cam follower 3 provided at the other end of the swing lever. Transfer head 2 and the cam 7 roller 3
A plate cam 4 that controls the rotational posture of the swing lever 1 by having a U-shaped groove e in which the cam 7 op 3 fits in the center of the contact side, and the temporary cam 4 a tension spring 6 that keeps the cam follower 3 in constant contact with the cam follower 3;
A connecting rod 13 is provided for moving the swing lever in the front and rear directions around its center of rotation, so that the front and back direction and the swing direction of the transfer head can be driven by the same drive.

Effects of the Invention As described above, the present invention provides a structure in which the cam follower fits into the U-shaped groove of the plate cam so that the swing lever that can be moved in the front and rear direction is
Since the transfer head can be rotated by matching, it is possible to perform the forward/backward and turning movements of the transfer head section with the same drive.
