Abstract

PURPOSE:To cope with change of work accurately and quickly by supporting plural sets of holding pieces corresponding to plural kinds of works allowing escaping from work holding position and providing a locking mechanism that positions each holding piece to the work holding position. CONSTITUTION:A holding piece 13 which is necessary to cope with the shape of a work is selected out of plural kinds of holding pieces 13. This holding piece 13 only is made to horizontal state by rotating an arm 12 so that the holding piece comes to the upper side. By this way, only the selected holding piece is positioned on the work carrying passage and becomes work holding position. For unnecessary holding pieces 13, a locking mechanism 15 is released, and they are escaped into a base 10 by rotating the arm 12 by 180 deg. so that these holding pieces come to lower side.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of an idle stage for temporarily stopping all workpieces in a press line.

For example, in a press machine for automobile body panels, when a workpiece that has been completely formed by a first press machine is automatically supplied to a second press machine for the next press process,
An idle stage* is installed between the first press machine and the second press machine, where all the workpieces are temporarily stopped and transported. , Ml is a first press machine, Ml is a second press machine, and three idle stages s1°"2,"+1 are installed between them. When the processing of the first press machine M1 is completed, the hand link device H is activated to support the workpiece w1 on the press machine Ml and the workpiece w2 waiting on the idle stage Sl, and the workpiece W+ 'fc
Transfer the workpiece W2 to the idle stage s1 and the workpiece W2 to the idle stage S2 (9) At this time, the other handling device kf is synchronized with the handling device fjl H1.
lit, H2 also works at the same time.1. Wa Yuuri W on Idol Stage 82.

to idle stage Sa, and also to idle stage S3.
The upper workpiece W4'c is transferred to the second press machine M2. By repeating this operation for each cycle of the press, the finished workpiece can be fed to the next press machine.

By the way, as a concrete wheel base for the above-mentioned idle stage, conventionally a plurality of bars 2 having bottle l projecting thereon are installed in parallel on a base 3 as shown in Figs. 2 to 4. Among the bars 2, a pair of left and right bars that can support the workpiece wirtC are provided, and a workpiece supporting surface having a support surface corresponding to the curvature of the workpiece is attached to the retracted bar as shown in FIG. It has a & construction with the receiving piece 4 fixed.

Here, the bar 2 and the receiving piece 4 are fixed by aligning the pin 1 provided on the bar 2 with the daruma hole 5 provided at the base of the receiving piece 4, as shown in FIG. . Then, at the workpiece epicenter, by fixing a new piece with a support surface corresponding to the workpiece shape to the bar 2 at the position where the workpiece W is stably supported and prayed, using the above-mentioned method. Dealing with heart.

However, with the structure of such a conventional idle stage, in the event of a work earthquake, it is necessary to remove the existing support pieces and then attach the support pieces, so it is difficult to install the support pieces. In addition to the risk of negative impacts, it is not only time-consuming, but it is also extremely complicated to perform the above work in a limited space2, and the storage and management of these songs is also complicated. There is.

This invention has been made in view of the above-mentioned problems of the conventional art, and a plurality of sets of receiving pieces corresponding to the workpieces of various sizes are supported in the position and retracted position b. ,
The object of the present invention is to provide a locking mechanism for positioning each receiving piece at a workpiece receiving position, thereby solving all of the above-mentioned problems.

The embodiments of this invention will be described below using drawings.
do.

Are Figures 5 and 6 an implementation of this invention? 10 is a base, and a rotating shaft 11 is horizontally mounted on the upper surface of the base 10, and on this rotating shaft 11, there are 3 pairs of arms 12 (combined H16) in this embodiment. These arms 1 are supported in parallel so that each valley can be rotated.
2 has a receiving piece 1 which is a supporting member having a different shape.
3'i (fixed with bolts 14).

A striker 1.5 & of the locking mechanism 15 is provided at one end of each arm 12, and a receiving member 15 corresponding to the striker 15a is provided on the upper surface of the base 10.
b is the installation. As a result, when the arm 12 is placed in a horizontal state as shown by the solid line in FIG. 5, the striker 15a and the receiving member 15b fit together, so that the arm 12 is held horizontally. On the other hand, a locking mechanism 15 consisting of the striker 15a and the receiving member 15b.
has a striker 15a'irM of 61J6 by a ball urged by a spring, and when an external force greater than the force of the spring is applied, the receiving member 15b and the striker 15
It has a well-known #) structure that allows the mating of a to be released.

According to the above-described configuration, only the necessary receiving piece corresponding to the shape of the workpiece is selected from among the countless receiving pieces 13, and only the selected receiving piece is moved into the arm so that the receiving piece is on the upper side. 12 is rotated and placed in a horizontal state, and locked by the locking mechanism 15 (the state shown in FIG. 5). As a result, only the selected receiving piece is located on the workpiece conveyance path, and the workpiece receiving piece is in position. Then, release the lock mechanism of the receiving pieces 13 that are not needed, and move the arm 12y so that these receiving pieces 13 are on the lower side.
It is okay to rotate it 1sog and retreat into the base 10 (
(state shown by the dashed line in FIG. 5). At this time, the receiving piece 13 housed in the base 10 is stopped by a stopper (not shown) to prevent it from being disturbed by external vibrations or the like. As a result, even if there is a work change, only the cheapest receiving pieces can be rotated, and on the contrary, unnecessary receiving pieces only need to be reversed. Also, work W
If the shape of the piece is extremely difficult, that is, if it cannot be handled with only the receiving piece prepared in advance, prepare only the receiving piece separately and take it to the arm! It's okay to replace it.

FIG. 7 shows another embodiment of the present invention. In the first embodiment, the center of rotation is at the longitudinal center of the arm 12, whereas in this embodiment, one end of the arm 12 is rotated. It is a central thing. As a result, in the MI arrangement embodiment, it is necessary to rotate the instrument by 180 degrees when using the receiver *] 13 selectively, whereas in this embodiment, the desired target sound can be achieved by only rotating it by 90 degrees. In this embodiment, the receiving member 15b of the lock and seal 15 is slidable in the direction of arrow B.

In this way, according to the present invention, by selectively retracting all of the receiving pieces, it is possible to use the receiving pieces of several buildings properly, so when changing the work, it is possible to quickly deal with the change of work without leaving the entire seagull. This has the effect of making complicated storage and management disrespectful.
