Description

[Detailed Description of the Invention] The present invention relates to a material supply device for an automated press line such as a transfer press, and is capable of improving the efficiency of press processing and reducing equipment costs.

When the blank material on the trolley that supplies material to the automated press line becomes empty, the current situation is that the factory crane or forklift supplies the blank material to the trolley each time while waiting for the factory crane or forklift to have free time. It is.

In such a system, the press work on the automated press line depends on the free time of the factory crane or forklift, and if there is no free time, the press work will be stopped and the efficiency of the press work will be reduced. It is not possible to improve or automate the process, and there are disadvantages such as the need for constant communication between the person doing the press work and the person operating the factory crane or forklift, which is troublesome.

In addition to the above-mentioned method, a loop-type material supply device to a cart using a chain or roller drive has been considered, but it is necessary to use a pallet to deal with sagging or catching of the blank material during conveyance. In addition, a recovery line for the pallets must be provided, making the mechanism complicated, large-scale, and expensive.

The present invention relates to a material feeding device for an automated press line, which was created in view of the above circumstances, and includes a plurality of blank material holders for loading blank materials arranged in parallel with the press line. A crane is disposed so as to be able to travel above, and a trolley is provided that is perpendicular to the traveling direction of the crane, travels between a blank material supply position of the press line and a position directly below the crane travel path, and is capable of carrying blank materials. , a fork having a plurality of fork units is installed on the crane so as to be movable up and down, and fixed pallets in the shape of comb teeth are provided on the top surface of the blank material holder and on the top surface of the cart, respectively, so that the fork units can move in and out, and the blank material is moved by the crane. The present invention is characterized in that it is configured to transfer the blank material from the pedestal to the cart.

Embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a plan view showing the configuration of the apparatus of the present invention. In the figure, 1 is an automated press line, and 2 is a rail 3 installed on the material (blank material) supply side of the automated press line 1 at right angles to the press line. 4 is a rail installed on both sides (or one side) of the automated press line 1 at right angles to the rail 3 and straddles above the rail 3; 5 is the rail 4; 6 is a blank material holder disposed on the traveling line of the crane 5, and 7 is a blank material.

The crane 5 also has a plurality of (six in the drawings) fork units 52 as shown in FIGS. 2 and 3.
A fork 51 having a fork 51 is movable up and down by a cylinder 53, and is equipped with a traveling device.

Furthermore, a fixed pallet 21 in the shape of a comb tooth is attached to the upper surface of the truck 2 so that the fork unit 52 of the crane 5 can move in and out and can be moved up and down. A fixed pallet 61 having a comb tooth shape similar to that described above is attached. In addition, 8 in FIG. 2 is a vacuum type pickup device.

The operation will be explained below.

First, when the factory crane or forklift opens, the blanks 7 are loaded onto the fixed pallets 61 of all the blanks holders 6 by the factory crane or forklift. A blank material 7 is supplied from the truck 2 to the automated press line 1 by a pick-up device 8 while being appropriately lifted by a lifting mechanism (not shown). At this time, the fork unit 52 of the crane 5 is inserted in advance into the groove of the fixed pallet 61 on which the blank material 7 of the blank material holder 6 is placed, as shown in FIG. Also trolley 2
The crane 5 may be operated as shown in FIG. 3 when the blank material 7 is transferred. Note that 71 is a clamping device for preventing the blank material from collapsing when the crane 5 is moved.

When the blank material 7 on the trolley 2 decreases, the reduced blank material 7 is held by a holding mechanism in the automated press line 1 (not shown), and during this holding, the trolley 2 is moved from the solid line to the imaginary line in FIG. The blank material 7 is moved as shown, and then the fork 51 of the crane 5 is raised appropriately to lift and move the blank material 7 to the upper surface of the fixed pallet 21 of the trolley 2. After that, the blank material 7 is lowered together with the fork 51 and placed on the fixed pallet 21 of the trolley 2. Transfer. At this time, the fork unit 52 is inserted into the groove of the fixed pallet 21, and in this state, the crane 5 is moved along the rail 4, the fork unit 52 is pulled out from the fixed pallet 21, and engaged with the truck 2. Solve the condition.

After doing the above, the cart 2 is moved from the imaginary line in FIG. 1 as shown by the solid line to supply the blank material 7 to the automated press line 1. Therefore, the blank material 7 can be continuously supplied to the automated press line 1 by the crane 5, improving the efficiency of press processing, and the factory crane or forklift can be used when loading the blank material 7 onto the blank material pedestal 6. Since it is only used, the blank material 7 can be supplied to the automated press line 1 without being greatly influenced by the idle time of the factory crane or forklift.

The present invention is not limited to the illustrated and explained embodiments, and may be applied to, for example, automatically supplying blank materials to a blanking line and each press line, etc. Of course, various changes may be made without departing from the spirit of the invention.

As described above, according to the material supply device for an automated press line of the present invention, (i) blanks can be supplied to the trolley using a dedicated crane without waiting for idle time of the factory crane or forklift, increasing the efficiency of press processing; Improvements can be made.

(ii) The press operator can operate a dedicated crane, resulting in labor savings.

(iii) It is less expensive than conventional material feeding devices for carts.

(iv) Press work can also be automated.

(v) Easy to operate.

Demonstrates excellent effects such as
