Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for pulling out a sheet-like material processed by a machine tool from the machine tool and transferring it to a predetermined location.

Conventionally, a pair of endless chains is used to sequentially load sheet materials carried in from a machine tool, and this pair of endless chains is provided with a receiving section and a space, and the sheet materials carried in sequentially by the receiving section are There are devices in which materials are sequentially loaded from a space to a lower loading section.

However, with conventional equipment, the endless chain suspended on the loading section becomes an obstacle in order to transport the sheet materials loaded on the loading section to the required location, making it impossible to install a cart for carrying out at this location. There wasn't.

For this reason, a lifter that moves up and down is provided in the loading section, and the sheet material is once loaded onto this lifter and moved downward, and then transferred to a truck or conveyor belt.

For this reason, there was a problem that the device was complicated and large.

The present invention has been made in view of these points, and one embodiment of the invention will be described below based on the drawings.The transfer device main body 1 shown in FIGS. 1 to 5 has four corner Vertical frame 3... Appropriate number of horizontal frames 4, 5.6
A fixed guide rail 7 made of H-shaped steel is installed at the center of the top of the main body of the device, and a horizontal frame 4 at both ends of the top is connected to the fixed guide rail 7.
, 4, and one end of this fixed guide rail 7 is connected to the table 9 of the machine tool 8 as shown in FIG.
The movable base 11 is extended to the position directly above the fixed guide rail 7 via rollers 10, and is movably suspended from the fixed guide rail 7.

12 is a forward/reverse motor mounted on one end of the fixed guide rail 7; a sprocket 13 driven by the motor 12 and another sprocket 14 are mounted on the one end; Sprockets 15 and 16 are mounted on the shafts, and both ends of a chain 17 wound over these sprockets 13 to 16 are tied to the movable base 11, and as the motor 12 rotates forward and backward, the movable base 11 becomes a fixed guide. It is moved back and forth in the longitudinal direction of the rail.

Reference numeral 18 denotes a clamp carrying means installed on the lower surface of the movable base 11, and the means 18 has clamp claws 19 and 19 for clamping the sheet material A.

Directly below this clamp loading means 18 is a machine tool table 9.
A sheet-like material carrying-in section 20 is formed at the same level as the sheet-like material carrying-in section 20, and a sheet-like material loading section 21 is formed directly below this sheet-like material carrying-in section 20.

In the sheet-like material loading section 20, a pair of guide rail members 22.22 parallel to the fixed guide rail 7 are installed facing each other on the inner surface of the intermediate horizontal frame 6.6. Sprockets 23 and 24 are respectively mounted on the vertical frame 3 or the horizontal frame 6 at both ends of the device main body 1, and the aforementioned guide rail members 2
A pair of endless chains 25.25, which are supported by 2.22 and move in circulation, are wound and suspended over the sprockets 23.24.

In this case, as shown in FIG. 1, the upper chain 25a of the endless chain 2'5 travels in the direction of carrying in the sheet material as shown by the arrow A, and the corresponding lower chain 25b travels in the direction indicated by the arrow A. As shown by B, it travels in the opposite direction, and is not connected to the feed table 9 or auxiliary table 35 of the machine tool.
and the lower side chevron 725b are arranged so that they are substantially flush with each other, so that the upper side chevron 25a is located above.

Of the above sprockets) 23.24, other sprockets 26.26 are coaxially connected to the left and right sprockets 23.23 on the loading start end side so as to rotate together as shown in FIG. In vertical frame 3,
The other sprocket 28 of the rotating shaft 27 that is laterally attached between 3 and 3.
28 is fixedly mounted, and the rotating shaft 27 and motor 29 are interlocked and connected via a sprocket 30.31 and a chino 32, so that the rotational force of the motor 29 is input to both sprockets 23.23 via the rotating shaft 27. By being
The pair of endless chains 25, 25 are synchronously driven.

Furthermore, between the pair of endless checks 725.25, there are a large number of receivers at required intervals not over the entire length in the running direction, but over a portion thereof, that is, at a distance corresponding to the length of the aforementioned guide rail member, or at a distance slightly shorter than this. Support bar 33a・
.

Reference numeral 34 indicates a large number of free-rotating balls that are held and partially protruded from the upper surface of the support bar 33a.

Note that an idling roller may be used instead of the support bar 33a.

Reference numeral 35 denotes an auxiliary table that bridges between the machine tool table 9 and the group of support bars 33. On the upper surface of this auxiliary table, a free rotating ball 36 is gripped in the same way as the support bar 33a. A push-up machine 37 is equipped.

Furthermore, 41 shown in FIGS. 1 and 2 is a group of support bars 33.
This is a limit switch that detects the completion of the upward reverse movement and the completion of the return movement to the original position and stops the motor 29.

In the above configuration, after the sheet-like material A is subjected to necessary processing, such as drilling, on the table 9 of the machine tool 8, the push-up machine 37 pushes up the end of the sheet-like material A, and the clamp carrying means 18 clamps the end of the sheet-like material A with its clamping claws 19.19.

Next, the motor 12 drives the cheno 7, and the movable base 11, that is, the clamp loading means 18, starts reciprocating, and the sheet material A is pulled out from the delivery table 9 of the machine tool 8, passes through the auxiliary table 35, and is transferred to the endless chain 25. is pulled onto the lower side chino 25b and placed on a group of support bars 33 suspended from the chino 25b.

Then, the sheet material A is completely transferred to the sheet material loading section 20.
When the clamp is pulled in, the clamp loading means 18 is stopped.

This stop position is a position slightly away from the cyclic movement locus of the endless belt 25 toward the carry-in terminal side, as shown by the chain line at the right end of FIG.

This is to prevent the support bar group 33 from coming into contact with the clamp loading means 18 due to the circular movement described later.

On the other hand, when the sheet-like material A is completely drawn in, the motor 29 is driven, and therefore the pair of endless chains 25 and 25 wound around the sprockets 23 and 24 start running. As shown in FIG. 7, the support bar group 33 which is applied laterally between . It reaches the loading start end and begins to turn upward, and along with this, the support bar group 3
Since the endless checks 725 and 25 other than 3 are open, the sheet material loading section 20 gradually communicates with the sheet material loading section 21 directly below from the right end side in the drawing.

Therefore, if the clamp claws 19 and 19 are removed from the sheet-like material A in advance at the time of communication, as approximately half or more of the sheet-like material carrying-in section 20 is communicated with the sheet-like stacking section 21, the sheet-like material will be removed as shown in FIG. One end of the material A begins to hang down inside the sheet material loading section 21 due to its own weight, and finally, the hanging end
The cart 38 being fed into the sheet material loading section 21
, and gradually adjusts to the direction in which it overlaps the trolley 38.

Therefore, when the group of support bars 33 is completely reversely moved upward, the sheet-like material A is separated from the group of support bars 33, transferred to the cart 38, and loaded thereon, as shown in FIG.

Also, contrary to the above explanation, the sheet-like material A is clamped by the clamp claws 19, 19 while the group of support bars 33 is moving, and is removed only after the group of support bars 33 has been reversely moved upward. In this case, upon completion of the reversal movement of the support bar group 33, the sheet material A is moved around the end clamped by the clamp claws 19 and 19 on the trolley as shown by the solid line in FIG. 38, then clamp 1
When 9.19 is opened, it is loaded onto the trolley 38 as shown by the chain line.

In order to prevent the sheet-like material A from being deformed when it hangs down around the clamp claws 19 and 19, the clamp carrying means 18 is pivoted to the movable table 11 so as to be movable up and down. Preferably, the tilting is accompanied by downward tilting, for example by means of a hydraulic cylinder 40 (shown in FIG. 1).

After the sheet material A is loaded onto the trolley 38, the endless chain 25.25 further travels, returns to its original position as shown in FIG. 6, and stops, in preparation for carrying in the next sheet material A. At the same time, the clamp carrying means 18 moves back toward the machine tool 8 side.

As described above, in the present invention, if the endless chain is driven after the sheet material is carried in, the idle roller group or the support bar group runs together with the chain 7 and moves upward from the feeding start end of the sheet material carrying section. Along with this, an opposing open part between both endless chains appears, and the bottom of the sheet material loading part is gradually opened and communicated with the sheet material loading part, so when the bottom part is completely opened, The sheet-like material is automatically transferred to the sheet-like material loading section and is loaded on the sheet-like material loading section, so that the sheet-like material can be automatically transferred to a predetermined location and The structure is extremely simple because it is only necessary to run a group of idle rollers or a group of support bars that constitute the bottom of the sheet-like material carrying-in section by means of an endless belt.

Furthermore, according to the present invention, an endless chain for carrying in material is suspended in circulation within the sheet material carrying section, so that the sheet material loading section below can be formed into a completely open space. Therefore, the loading section can be freely equipped with a cart for transporting sheet-like materials, and the sheet-like materials can be loaded and transported at the same time with a simple configuration.

In particular, according to the present invention, the endless chain suspended in the sheet-like material carrying-in section has its upper chain running in the carrying-in direction, and the corresponding lower chain 7 running in the counter-carrying direction, and Since the feed-out table surface of the machine tool and the lower checker 7 are arranged so as to be almost flush with each other, the sheet-like material sent out from the feed-out table surface is transferred to a group of idle rollers suspended horizontally on the lower checker 7. The sheet-like material is placed on a group of support bars and is sequentially loaded on the sheet-like material stacking section downward from the open section adjacent to these, and the sheet-like material is stacked from the lower checker 7 near the stacking section of the endless chain. Since the sheet material is transferred to the loading section, it is possible to reduce the amount of impact drop and deflection of the sheet material, and it is possible to prevent damage to the sheet material during transportation.
