Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for distributing a pair of left and right press products from a lower die to the outside of the machine in a press machine.

[0002]

[Prior Art]

 For example, when a pair of left and right parts such as an automobile door panel is press-molded, a pair of left and right parts are simultaneously press-molded. At the same time, when a pair of left and right press-formed parts are carried out of the lower mold, the left and right pressed products are distributed to the left and right sides of the lower mold and carried out.

As shown in FIG. 5, a conventional unloading device is provided with left and right downward inclined surfaces 3 a and 3 b for sliding a pair of left and right pressed products on a lower press die 1 to the left and right, and can be moved up and down by a cylinder 10. The lifter 2 is provided in the press lower die 1, and the chutes 4a and 4b are arranged at both left and right positions of the lifter 2.

[0004]

[Problems to be solved by the device]

 The above-mentioned conventional apparatus lifts the lifter 2 to lift a pair of left and right press products on the lower die 1 on the inclined surfaces 3a and 3b, slides them left and right, and slides them to the chutes 4a and 4b. However, the pressed product may stop in an inclined posture when it slides on the inclined surfaces 3a and 3b and reaches the chutes 4a and 4b.

In such a case, the operator extends his hand into the mold to correct the posture of the inclined press product, which is extremely dangerous. If the chute is placed at an angle, the above problems will be eliminated, but the chute may interfere with the upper mold, and improvement is desired.

An object of the present invention is to provide a press product unloading device that solves the above conventional problems.

[0007]

[Means for Solving the Problems]

 To achieve the above object, the gist of the present invention is to provide a lifter that can be lifted and lowered by a cylinder with a left and right downward inclined surface that slides by dividing the pair of left and right press products on the left and right sides. The chutes are provided on both left and right sides of the lifter so as to be able to move up and down through a guide shaft in the same direction as the lifter moves up and down, and support shafts are provided on the left and right of the lifter in parallel with the guide shaft of the chute. An arm, which is fixed in the axial direction and has one end in contact with the lower end of the guide shaft, is provided between the support shaft and the guide shaft so as to be vertically swingable, and when the lifter descends on the support shaft. Only, a pendulum lever that pivots by contacting the other end of the arm and swinging the arm is pivotally supported.

[0008]

[Action]

 With the above configuration, when the lifter descends from the ascending end, the chute is moved up in conjunction with the downward movement of the lifter, and the posture of the press product tilted between the lifter inclined surface and the chute is corrected. Surely carry it into the chute.

[0009]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, reference numeral 2 is a lifter, which is provided on the lower mold 1 so as to be movable up and down by a cylinder 10. On the upper part of the lifter 2, left and right downward inclined surfaces 3a and 3b are formed, which slide the pair of left and right pressed products WR and WL on the lower mold 1 to the left and right.

A chute 4 a (one chute is omitted) is arranged at both left and right positions of the lifter 2 so as to be able to move up and down in the same direction as the lifter 2 via a guide shaft 5.

Further, support shafts 7 (one support shaft is omitted) are fixed to the left and right of the lifter 2 in the axial direction parallel to the guide shaft 5 of the chute 4 a, and the support shaft 7 and the guide shaft 5 are connected to each other. An arm 6 whose one end is in contact with the lower end of the guide shaft 5 is provided so as to be swingable in the vertical direction, and is brought into contact with the other end of the arm 6 only when the lifter 2 moves downward on the supporting shaft 7. This is a structure in which a pendulum lever 8 for swinging the arm 6 is pivotally supported. Incidentally, 9 is a stopper of the pendulum lever 8.

Since the present invention has the structure as described above, when the lifter 2 moves from the lower end of the lifter 2 shown in FIG. 1 to the upper end as shown in FIG. Although it abuts against the end, the pendulum lever 8 at that time rotates in the direction opposite to the direction in which it is constrained by the stopper 9, so that the arm 6 does not swing due to so-called idle driving, and the chute 4a does not move. It stays at the falling end of the position.

The press products WR and WL on the lower die 1 are lifted by the inclined surfaces 3a and 3b by the ascending movement of the lifter 2 and slide on the inclined surfaces 3a and 3b to fall on the chute 4a. At this time, some of the pressed products WR and WL are correctly carried into the chute 4a, and some of them are stopped in the posture of the inclination angle along the inclined surfaces 3a and 3b and enter the chute 4a.

However, in the present invention, when the lifter 2 moves down from the rising end, as shown in FIG. 3, the pendulum lever 8 contacts the other end of the arm 6, and the pendulum lever 8 is rotated by the stopper 9. Is restrained, the arm 6 rotates in the direction of raising the guide shaft 5 as the lifter 2 moves downward.

As a result, the chute 4a moves upward relative to the downward movement of the lifter 2 and stops at the inclination angle along the inclined surfaces 3a and 3b, so that the press products WR and WL contained in the chute 4a are stopped. At some time, the tilted posture is corrected, and the chute 4a is correctly accommodated and raised. The pressed products WR and WL are taken out from the raised chute 4a, and then the chute 4a is automatically returned to the descending end by its own weight and waits until the next discharging cycle.

[0016]

[Effects of the Invention] As described above, according to the present invention, a lifter that is vertically movable by a cylinder is provided with a left and right downwardly inclined surface that slides a pair of left and right pressed products on the lower press die to the left and right. The chute is arranged on both left and right sides of the lifter so that it can be moved up and down through a guide shaft in the same direction as the lifter is moved up and down. An arm whose end is in contact with the lower end of the guide shaft is provided between the support shaft and the guide shaft so as to be vertically swingable, and only when the lifter descends on the support shaft. Since the pendulum lever that abuts on the other end of the arm and swings the arm is pivotally supported, it is possible to reliably carry out the pressed product without stopping it on the chute, improving worker safety. There is an advantage to
