Abstract

PURPOSE:To make the whole of a titled device small-sized, and to make an exclusive floor area narrow and small, by combining and using 3 air cylinders, sucking a blank material to a suction board, shifting it in order to plural press bases, and executing several workings continuously. CONSTITUTION:When the first air cylinder 12 is lengthened and subsequently the second and third air cylinders 18, 27 are shortened, a running lever 16, a fixed arm 21 and each rocking arm 22 ascend and move to the right, a suction board of the fixed arm 21 is positioned on a blank material 30, and each rocking arm 22 is saved from on a press base 28. The third air cylinder 27 is lengthened, the first air cylinder 12 is shortened, and the blank material 30 is sucked by the suction board 24 of the fixed arm 21. The first air cylinder 12 is lengthened, the second and third air cylinders 18, 27 are lengthened, and subsequently, the second and third air cylinders 18, 27 are shortened, and when the sucking operation is stopped, the blank material 30 is placed on a die 29 on the right end of the press base 28. Subsequently, the suction board 24 of the rocking arm 22 is sucked from the right in order, and by repeating said operation, the blank material 30 is moved onto the press base 28 in order and is placed.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an automatic material feeding device that is extremely effective when used to perform several consecutive processes on the same material, such as press processing. - Conventionally, various types of equipment used for this purpose have already been provided, but they are limited in the number of continuous processing, are slow in operation, are complex and large, and are therefore expensive and require a large floor space to install. It had the disadvantage that it was required to be a counterfeit.

The present invention has been made to solve the above-mentioned drawbacks, and based on the attached drawings below, the upper surface of the horizontally elongated substrate (1) is , pillars (2) (2) are erected, and each pillar (2) has a pair of front and rear pillar pieces (2a) (2
a).

At the center of the upper part of each column (2) is a lifting rod (
3), and a link (4) facing downward to the left in FIG. 1 is pivotally attached to the lower end of the lifting rod (3).

On the left and right links +4) (4), horizontal rods +51<6) facing right, respectively, hold the horizontal pins (7)<7) and move the rollers 18>! 81, and each roller (8
), the receiver attached to the top surface of the board (11) rests on the plate (9).

Both lateral inner rods f5) (6) are -
Bearing 1+ connected in a straight line and fixed to the substrate (1)
11111, it is slidably supported.

The connecting fitting (l) is the piston rod of the first air cylinder 1121 (which is shortened in FIG.
The tip of 12a') is fixed.

Therefore, as shown in FIG.
When 21 is extended, both lateral inner rods +51t6) move to the right, each link (4) faces vertically, and lifts up the elevating rod (3).

Support metal fittings (13) are fixed to the upper surfaces of the left and right lifting rods (3) (3), respectively, and both support metal fittings ++31 +1
On the upper surface of 41, there is a U-shaped guide fitting ++5i on the side.
EI51 is fixed.

Both guide fittings 151 (a horizontal square rod-shaped running rod (16) fits into the groove on the upper surface of 151, and a bracket 07 vertically installed on the right side of the lower surface of the running rod (+6)), The second air cylinder (piston rod 181), which is fixed to the right support bracket Oa in the left direction and extends as shown in Figure 1,
The tip of 18a) is fixed.

A plurality of second mounting brackets (to) are fixed to the left side of the first mounting bracket a1 at approximately equal intervals.

On the top surface of the first mounting bracket a9 is a fixed arm Ql) facing forward.
is fixed to the upper surface of each second mounting bracket (4), and the vicinity of the rear end of each swinging arm Qz facing forward in FIG.

On the lower surface of the front end of the fixed arm Qυ° and each swinging arm, there are two suction cups (two suction cups) serving as a material gripping device connected to an appropriate suction device (not shown), and each suction cup 1241 is Running rod Oe
They are arranged more equidistantly and equally spaced from each other.

When the second air cylinder 118) is shortened, as shown in FIG.
4), travels to the right on both guide fittings 1151 (151).

The rear of the vertical pin (23) in each swinging arm (22) is bent toward the left rear at an equal angle, and its rear end is parallel to the running rod (+6) with vertical piers QS of equal mutual spacing. 3, connecting rod 1 which is pivoted to the eggplant, connecting rod 1)
26), the tip of the piston rod (27a) of the third air cylinder (2n) extending in FIG. ing.

The running rod (161), the rear part of each swinging arm @, and the linking rod (26) form a parallel lick as described above, so when the third air cylinder @ is shortened, as shown by the imaginary line in Figure 2, Number, each swinging arm f25 is pin +23)'! Instead, it swings to the left at an equal angle, and the running rod (1)
, +281 if in FIG. 2 is a press table installed in front of the substrate (1), (to) is a lower press mold, 130) is a stacked material, and C311 is a storage box for processed products.

Next, the operation of the apparatus of the present invention having the above-mentioned structure will be explained in FIGS. 5a to 5e.
The diagram will be explained.

In addition, in FIG. 5a to FIG. 5e, illustration of the press lower mold (end) is omitted.

FIG. 5a, that is, when the first air cylinder (121) of the apparatus in the state shown in FIGS. As shown in the figure, along with the running rod o0,
The fixed arm Cυ and each swinging arm (22+) rise and move to the right, so that the suction cup Q41 of the fixed arm Qυ is located above the stacked material ■, and each swinging arm (727 moves to the left). It swings and retreats from above the press table □□□.

At this time, the upper die (not shown) of the press device descends,
When this apparatus is started, as shown in the figure, there is no material on the press stand (2), so the press is empty.

Next, as shown in Fig. 5c, the sixth air cylinder (
2) is extended and each swinging arm (rib faces forward), the first air cylinder u3 is shortened, and the suction cup Q41 of the fixed arm Qυ descends to the center of the upper surface of the stacked materials (7). Since the upper end material (7) is pressed against the upper end, the material (7) is attracted.

After that, extend the first air cylinder (12!),
Next, after extending the second Φ sixth air cylinder 081@, the first air cylinder (121) is shortened, and the suction cup C2
If the adsorption action of 1j is stopped, as shown in Figure 5d,
The material (2) is placed on the lower die (not shown in FIG. 5d) at the right end of the press table.

The state of the device at this time is similar to that shown in FIG. 5a.

Again, as shown in Figure 'Se, the first air cylinder 112+ is extended, and then the second and third air cylinders 112+ are extended.
By shortening (3) and lowering the upper mold of the press when each swinging arm (23 is retracted from the press table (2), the first material (to) is Processed.

After that, as shown in Fig. 5F, extend the third cylinder/da@, and after each swinging arm (22) faces forward, shorten the first air cylinder a2 and lower the right end. Next, as shown in Fig. 5g, the first air cylinder is extended, and then the first air cylinder 112 is shortened, and both Suction cup (2
If you stop suction repair of A4, the image material (to) (to) will be
The lower molds are respectively placed on the second and first lower molds from the right on the press stand.

By repeating the above operations 1. It is sent to the left in Fig. 5h, and the suction cup at the left end (the storage box 13 below 241)
1) and is stored.

As is already clear, the device of the present invention described above has a swing arm (7
21t, the number of machining can be arbitrarily selected by increasing or decreasing.
Moreover, during press processing, each swinging arm (a) is retracted from above the press table, so there are no restrictions on the processing or the shape of the material. .

In addition, the horizontal length #1 is equal to the length of the press device and the storage area for the stacked materials attached to it and the processed product storage box C311, which is the minimum necessary length, and the front-to-back length is:
It is extremely short and has a small rectangular shape as a whole, so
.

It requires only a small amount of floor space and is easy to install.
- Furthermore, because the device is relatively simple and compact, it can be manufactured inexpensively and there is no risk of failure.
