Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a work loading device that can automatically load works pressed by a transfer press or the like using a work loader. and a container for the device.

[Prior Art] Conventionally, a workpiece formed by a transfer press is transferred to a conveyance device such as a chain conveyor installed downstream of the transfer press, and is conveyed to a predetermined position by the conveyance device. It was unloaded from the transport device by a worker and loaded into a container.

However, as mentioned above, manually unloading the workpiece from the conveyor and loading it into the container by a worker reduces the production capacity of the transfer press. The work is highly dangerous because the work is close to the moving parts of the equipment, and it is not possible to save labor because it requires multiple workers. 2.
Workpieces that are molded at a rate of once every 5 to 4 seconds are sent out from a transfer press, and are large in size, approximately 1500 mm wide x 2000 to 2500 mm long, and weigh approximately 20 to 30 kg. During the work, it is difficult to unload the workpiece from the unloading device and load it into a container, and the danger of the work increases.

Therefore, in recent years, workpiece loading devices and containers for the devices have been considered that would allow a workpiece loader to automatically take out and load the workpieces formed by a transfer press without relying on the manual labor of workers. There is.

An example of a workpiece loading device and a container for the device will be explained with reference to FIGS. 4 and 5.

A container transport conveyor 4 is provided with a workpiece positioning device 2 for positioning the workpiece 1 sent from the transfer press on the floor surface, and supplies a container 3, which will be described later, to pass through a workpiece loading station on the side of the workpiece positioning device 2.

The container 3 has bosses 7 and 18 erected from four corners of the rectangular bottom in order to vertically stack the workpieces 1, and bosses 7 and 18 are installed between the posts 1 and 17 and 17 on one side of the container 3. A horizontal shaft 19 is horizontally installed, and a plurality of spacers 20 are separately rotatably attached to the shaft 19 to be inserted between adjacent works 1.1 so as not to damage the work 1 loaded into the container 3. 1-18 on the other side of container 3.
A horizontal shaft 21 is installed horizontally between the workpieces 1.1 and 18, and a spacer 22 is inserted between the workpieces 1.
A plurality of INN fixtures 24 are fixedly attached to the container 1 so as to be rotatable separately, and the INN fixture 24 has a plurality of concave and convex portions 23 on the bottom of which are adapted to lock the lower part of the workpieces 1 to be loaded into the container 3. .

Next, the operation will be explained.

When the workpiece 1 formed by the transfer press is sent to the workpiece positioning device 2, the workpiece 1 is positioned by the workpiece positioning device 2, and then the workpiece rotor 6 waiting above the workpiece positioning device 2 is moved. The mast 12 is lowered, the vacuum pad 16 attached to the lower end of the mast 12 is brought into contact with the upper surface of the workpiece L, and the inside of the vacuum pad 16 is evacuated, thereby moving the workpiece 2 onto the arm 1.
Adsorb to 5.

After the work l is attracted to the arm 15, the work positioning device 2 is released and the mast 12 is raised by 1" to raise the work l to a predetermined height.

While or after the work 1 is raised to a predetermined height by the work loader 6, the rotor main body 9 holds the work 1 and moves the container 3 along the rail 7 to a work loading station in the middle of the waiting container transport conveyor 4. Run until. Therefore, the arm 15 together with the frame 14

Move the workpiece 1 held by the arm 15 so that it is next to the
When the workpiece 1 is inserted into the container 3 so that it is locked on the uneven part 23 of the container 3, the workpiece 1 is held by the arm 2 for a while, and the corresponding spacer is inserted into the container 3. 20.22 is rotated to lock both sides of the workpiece 1 (workpiece partitioning work), and the workpiece 1 is loaded into the container 3 so as not to come into contact with the adjacent workpiece 1 and be damaged.

Once the work is loaded into the container 3, release the vacuum pad 16, raise the square 1 and 2, and return the frame The positioning device 2 is made to stand by above.

Thereafter, by repeating the above steps, the works 1 are sequentially loaded into the container 3.

[Problem to be solved by the invention] However, in the work loading device and the container for the device described in 1. Since the workpiece 1 is provided with a plurality of spacers 20 and 22 that separately lock each side of the workpiece 1, the workpiece 1 can be secured to the container 3 at one lower part with the fixing jig 24 in the workpiece loading station. When loading the workpiece to be inserted, spacers 20°2 are placed on both sides of the workpiece 1.
Is it necessary to do the work partitioning work that is locked in step 2 at the same time?
During this time, the arm 15 of the work loader 6 must continue to hold the work 1, and the work loader 6 cannot be immediately moved to the next work loading cycle, which lengthens the work loading cycle and places the work in the empty container 3. It took a lot of time to fully load 1, resulting in poor production efficiency.

In addition, since the container 3 is designed to separately lock each side of the workpiece 1 one by one using a plurality of spacers 20 and 22, it takes a lot of effort to put in and take out the workpiece 1 in general, including the above-mentioned work loading operation. It took a lot of effort.

In view of a series of actual circumstances, the present invention improves production efficiency by making it possible to immediately move on to loading the next workpiece after inserting a workpiece, and also by making it possible to lock a plurality of inserted workpieces at once. 1. To provide a workpiece loading device that simplifies loading and unloading of workpieces and a container for the device.
