Description

[Detailed Description of the Invention] The present invention relates to a blank stacking device that feeds blanks cut by a blanking press into a destacker installed in a transfer press or the like.

Conventionally, this type of blank stacking device stacks blanks cut by a blanking press one by one, stops the blanking press when a predetermined number of sheets is reached, and
There is a known method in which a predetermined number of stacked blanks are transported and fed by a forklift or the like to a destacker installed in a transfer press or the like.

A blank material stacking device having such a configuration has a problem in that each process is performed separately and the blank material cannot be efficiently fed to the disk stacker.

The present invention was developed in view of the above circumstances, and its purpose is to provide a blank stacking device that can efficiently feed blanks cut by a blanking press to a disc stacker.

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

A blanking press 1 is installed continuously on a coil line A to cut a blank B from a coil material.

A main conveyance path C is provided on the discharge side of the blanking press 1, and first and second auxiliary conveyance paths D are orthogonal to the main conveyance path C.
The first and second auxiliary conveyance paths D1.D2 are provided at a position below the main conveyance path C. D2 is orthogonal to the first and second discharge paths E1. E2 is provided.

The first and second auxiliary conveyance paths D1. In D2, the first and second carts 21 and 2 □ are located at the blank material receiving position A (intersection with the main conveyance path C) and the blank material delivery position opening (the first and second transport path E □
, intersection with E2), and is provided so as to be reciprocally movable by cylinders 3□ and 3□ for moving the first and second carts, and
Blank material B on the trolley is placed at each blank material delivery position opening.
to the first and second unloading paths E1. The first and second bushings 41.4° are provided with first and second bushing cylinders 4a1 and 4a2 that feed into E2.

In the first and second unloading paths E and E2, there are first and second stackers 61 and 6° for conveying the blank materials installed in the first and second transfer presses 51 and 5° one by one to the transfer press 5. are successively installed via destacker conveyors 71 and 7°.

Each of the blank material receivers is in position A, and each carriage 24, 2□ is in position A.
Fixed guides 8 covering the three sides are provided on the base 9 so that the mounting position can be adjusted freely according to the size of the blank material B, and each trolley 21, 2□ is provided with a movable guide covering one side thereof. 10 are respectively provided, and each fixed guide 8 and movable guide 10 are configured so that the blank materials B can be stacked correctly on the trolley 2.

The main conveyance path C includes a first roller controller 11 that conveys the blank material B to a position A where the blank material receiver of the first trolley 21 is located, and a blank material receiver of the second trolley 2° that is continuous with the first roller controller 11 that transports the blank material B to a position A. The blank material receiver of the two carts 22 extends to A, and the switching roller controller 13 is supported on the switching cylinder 12 so as to be movable up and down on the switching cylinder 12 on the A side, and the guide piece 16 provided on the unloading side of the first roller controller 11 It is composed of:

The first and second auxiliary conveyance paths D1. D2 is composed of a pair of guide rails 14, 14 provided on the base 9, and the first and second discharge paths E□, E2 are configured by a conveyor 15 that rotates freely in the feeding direction and is driven by a separate drive device. It is composed.

Further, a roller control unit 17 is provided on the upper surface of the first and second carts 21 and 2°.

Next, the operation will be explained.

The switching cylinder 12 rotates the switching roller controller 13 upward to make it discontinuous with the first roller controller 11.

(Situation shown in Figure 2) In this state, the blank material B cut by the blanking press 1 moves along the first roller controller 11, is guided by the guide piece 16, falls one by one onto the first cart 21, and is stacked. .

Then, blank material B up to the 1st limit switch intestine □
When the roller controller 1 is stacked, the first limit switch LS1 detects it, and the cylinder 12 for switching is operated, and the switching roller controller 1 is activated.
3 rotates downward to a position where it is continuous with the first roller controller 11, so that the blank material B falls onto the second cart 22 and is stacked.

At the same time, the first truck moving cylinder 31 operates and the first
The carriage 21 is moved along the guide rail 14.14 to the blank transfer position.

This operation is detected by the second limit switch LS2, and the first pusher cylinder 4a□ is operated by the detection signal to push out the blank material B on the first cart 21 to the first unloading path E, and the pushed out blank material B are sent to the first de-stacker 6□ by the de-stack conveyor 71, and conveyed one by one to the first transfer press 51.

The completion of the extrusion is detected by the third limit switch LS3, and the detection signal causes the first truck moving cylinder 3 to be activated.
□ is operated, the blank material receiver of the first cart 21 is moved back to position A, and the first bushing ring is returned to its original position and stands by in preparation for the next operation.

These operations are performed by the fourth and fifth limit switches LS4.
LS, and ends until a predetermined number of blank materials B are stacked on the second cart 2□.

Next, when a predetermined number of blanks B are stacked on the second cart 2 □, the sixth limit switch S6 operates to detect, and upon this detection, the switching cylinder 12 operates, the switching roller controller 13 rotates upward, and the first roller controller 11, the blank material B is dropped and stacked on the first cart 2□.

At the same time, the second cart 2° is moved to the blank material transfer position opening in the same manner as described above, and the blank material B on the second cart 2□ is pushed out to the second carry-out path E2.

As described above, the blank material B can be automatically conveyed to the de-stackers 6□ and 6□, and the blank material can be efficiently fed to the de-stackers. Since the blanks are stacked on the cart 2□, the blanking press 1 does not need to be stopped and the operating rate of the blanking press 1 can be improved.

Since the present invention is configured as described above, the blank material B is cut by the blanking press 1 and then passed through the main conveyance path C to the first
Second auxiliary conveyance path D1. Either the first or second of D2
Since it can be stacked on the carts 21 and 2□, either the first or second cart 21.2° carries the blank material B to the delivery path E.
,,E2, when either of the other 2nd . 1st
Trolley 2□.

The blank materials B can be stacked on the blanking press 21, and the blank materials B can be transported without stopping the blanking press 1.

Therefore, the blank material B cut by the blanking press 1 can be efficiently fed into the distack 6□, and the operating rate of the blanking press 1 can be improved.
