Abstract

PURPOSE:To perform conveying work of a machined article between plural sets of machines by a small number of sets of conveying devices, by providing attracting means in at least 3pts. at an equal distance in a conveying bar which vertically and laterally moves. CONSTITUTION:Three arms 13, 14, 15 are mounted to a conveying bar 5' respectively at an equal distance, and each arm provides an attractive board 16, 17, 18. The conveying bar 5', first being stopped in its lifted position next being moved in a leftward direction by a driving gear 4, ceases this movement when the attractive board 16 moves to a position directly above a metal mold 1b. Next, the bar 5' lowers, and the attractive board 16, being brought into contact with a press work material on the metal mold 1b, attractively catches the material. And then the bar 5' is lifted, moving the board 16 rightward till it comes to a position directly above an intermediate bed 12, thereafter the bar 5' lowers causing the board 16 to release the material. Lastly, the bar 5' is lifted and moved returning in the leftward direction by a half stroke.

Description

[Detailed description of the invention] The present invention relates to a workpiece conveyance device.

For example, in a general press operation, a series of operations are performed in which press materials *31 are carried in, positioned, processed, and carried out for each press. Various proposals have been made to automate this work, particularly loading and unloading, in order to perform the work without human intervention in terms of safety and efficiency. An example of this is shown in FIG. In the figure, 1 and 2 indicate the shape of the press, 1a and 2a are the work beds, 1b and 21
+ indicates each mold. Reference numeral 3 denotes a conveyance device disposed between the presses 1 and 2, and includes a drive device 4 and a conveyance bar 5. The conveyance bar 5 is supported horizontally by the drive device 4 and is vertically aligned with the paper surface. It is configured so that it can be moved in the right and left directions. 6 and 7 are lid arms installed at both ends of the transfer bar 5, and suction cups 8 and 9 are installed at the tips of these arms. 10 is a press material loader section, 11 is an unlobe section, and 12 is a lid arm. Each intermediate stand is shown.

Now, in the conveying device configured as described above, first, the feed bar 110 is stopped at the illustrated position and at the raised position.

When the press machines 1 and 2 are about to complete one step, the transfer bar 5
moves to the left, the suction cup 8 comes directly above the mold 111, and this movement stops. At this time, the suction cup 9 is located directly above the intermediate stand 12. Next, the conveyance bar 5 is lowered (in the direction perpendicular to the plane of the paper and opposite to the front side), and the suction cup 8 is moved onto the mold 11) by a loading device (not shown) from the loader section 1o. At the same time, the suction cup 9 is placed on the intermediate stand 12 by the suction cup 8 in the previous process.
2. Adsorbs the sent press material. Next, the conveyor bar 5 is moved with the suction cups 8 and 9 suctioning the press materials.
The suction cup 8 is raised (to the front side in the direction perpendicular to the plane of the paper), and after being raised, it is moved to the right until the suction cup 8 is directly above the intermediate stand 12. Furthermore, the suction cup 8.9 descends at that position and releases the press material it was holding, so that the press material 1 on the mold 11) is fed 1 m onto the intermediate tables 1 and 2, and The upper press unit is conveyed 1" onto the mold 2b. In conjunction with this operation, a loading device and an unloading device (not shown) transfer the press unit of the rotor portion 1o to the mold 1.
At the same time, the press material on the mold 2b is carried out to the unloader section 11. Finally, the transport bar 5 is raised and moved half a stroke to the left, returning to the initial position shown in FIG.

By repeating the series of operations described above, the repress material is sequentially sent 110 times from the loader section 10 to the unrotor section 11.

By the way, in such a LK device that has been proposed in the past, the suction cups 8 and 9 are placed only on both ends of the conveyor bar 5, as described above, so one suction cup a88 can be used for one joint. 1 piece of wood that has been processed using the press machine 1
is transferred to the intermediate stand 12F between the press machines, and the other suction cup 9
Then, the presses conveyed onto the intermediate stand 12 are conveyed to the other press machine 2.

However, when a number of press machines are used and the press material is to be conveyed sequentially between these press machines, the previously proposed conveyance apparatus described above requires one conveyance apparatus for each press hall. Therefore, in addition to adjusting the operation timing of the conveying device and the press machine, it took a great deal of time to set the mutual timing of the conveying devices installed between the press machines. Further, in the conveying device explained with reference to FIG. 1, a loading device and an unloading device had to be specially prepared. Furthermore, 111 per press Isoma
This method has various drawbacks such as the need to secure space for installing the feeding device.

The present invention has been made in order to eliminate the above-mentioned drawbacks, and provides a conveying device that can carry out the work of conveying workpieces with a plurality of processing units using as few conveying devices as possible. The purpose is to

In order to achieve this object, the present invention is such that suction means are installed at equal intervals at three or more locations on a conveyor bar that is moved vertically and horizontally.

An embodiment of the present invention will be described below with reference to the drawings. FIG. 2 is a schematic plan layout diagram showing an example in which the 110 feeding device of the present invention is applied to FIG. 1. The same parts as in FIG. The difference from the figure is that the transport bar 5- has three arms 13.
14 and 15 are installed, and suction cups 16, 17, and 18 are installed on each arm.

To explain the operation of the conveying device constructed in this manner, first, the conveying bar 5- is at the position shown in FIG.
(The front side perpendicular to the page). Next, the transport bar 5' is moved to the left by the drive device @4,
This movement stops when the suction cup 16 moves to just above the mold 1b.

Next, the Iffl feed bar 5'' is lowered, and the suction cup 16 comes into contact with the press month on the mold 1b, and in this state, the suction cup 16 attracts the press month.Afterwards, while maintaining this state, the conveyance bar 5'' It rises and is further moved to the right until the suction cup 1G is directly above the intermediate stand 12.

Thereafter, the conveyor bar 5' descends, and the suction cup 1G releases the pressed material that has been suctioned and held.

Finally, the conveyor bar 5'' is raised and moved half a stroke to the left, returning to the state shown in FIG. In conjunction with the above-described movement, the nasty press material is supplied to the mold 11) from the loader section 10 by a loading device (not shown).

The above explanation focused on the suction plate 16, but the suction cups 17 and 18 also move in the same way as the suction cup 16, and perform suction and release operations, respectively. onto the mold 211, and the press material on the mold 2b is conveyed to the unrotor section 11.

(3) By repeating the same operation, the rotor part 1
The press 1.2 supplied from 0 is processed by the press 1.2, and finally stored in the unloader section 11.

In this embodiment, each suction cup 16.

Furthermore, the four rotary shafts slide along the long holes 33a installed in the swing plate 33 in the bearing portion 53a of the lever 53 which rotates around the support shaft 52 installed in the block 21. It is rotatably supported by a freely movable IN moving platen 54.

Further, a gear 55 is fixed to the other end of the rotating shaft 49,
This gear 55 has a meshing relationship with a rack 56 installed along the longitudinal direction on the side surface of the conveyor bar 5'.

In addition, only the arms 14 and 15 are shown on the conveyor bar 5- in FIG.

The operation of the conveyance device configured in this way will be explained in detail. First, the vertical movement of the suction cups 16, 17, and 18, that is, the vertical movement of the conveyor bar 5' will be explained. Reversible rotation
The output shaft 42 of 941 is rotated by an appropriate angle in the direction of the arrow from the position shown in FIG.

This movement causes the lifting rod 39 to rise, and this movement is transmitted to the lever 26, spindle 34, roller 36, rocking plate 33, spindle 35, roller 37, and lever 27 on one side, and to the rod 38 and lever on the other side. 28, roller 30, rod 32, lever 29.1] - roller 31, therefore rollers 30.31.3G, 37 are each connected to the support shaft 24.25

You can understand what is possible if you return to the state shown in the diagram.

Next, the movement of the conveyor bar 5' in the left-right direction will be explained in detail.

When the output shaft 47 of the reversible rotary motor 45 is rotated in the direction of arrow B, this movement is transmitted through the belt 51 to the pulley 50. The rotational movement of the gear 55 in the direction of arrow C, which is transmitted to the rotational shaft 49, moves the rack 56, that is, the conveyance bar 5' to the left in the figure, and this movement depends on the rotational speed of the rotational shaft 41. In addition, to move the general feed bar 5- to the stone gate in the figure,
It will be understood that the output shaft 47 of the reversible motor 45 may be rotated in the direction opposite to arrow B.

Note that when the conveyor bar 5' performs the above-described vertical movement, the rotating shaft 49 to which the gear 55 is fixed is supported by a bearing portion 53a whose one end is rotatably supported by the sliding plate 54, and the lever 53 rotates about the support shaft 52 following the vertical movement of the conveyor bar 5', so that the meshing relationship between the gear 55 and the rack 56 can be maintained at all times.

Next, another embodiment of the present invention will be described with reference to FIG. The difference from the above-mentioned embodiment is that four arms each having a suction means are installed on the conveying bar at equal intervals, and that the driving part of the conveying device is built into the press machine. Fourth
In the figure, 60.61.62 is a press machine, 60a

is a conveyance device, a drive device 64, an Ila feed bar 65.4
It consists of book arms 66, 67, 68, 69 and suction cups 70, 71, 72, 73 provided at the tips of each arm. Note that reference numerals 74 and 75 indicate intermediate stands installed between the press machines, and as the driving device 64 can be the same as that explained using FIG. 3, the explanation thereof will be omitted. Also, the press material is carried into the mold 60 b.
The apparatus for producing 1 ffJ from the mold 621) is omitted from illustration.

Now, the conveyance device configured as described above is stopped at the illustrated position and the raised position (perpendicular to the plane of the drawing and toward the front). First, the drive device 64 moves the conveyor bar 65 to the left in the figure, and this movement stops when the suction cup 70 is positioned directly above the mold 60b. Next, the conveyor bar 65 descends (perpendicular to the page and in the opposite direction from the front), and the suction cup 70
adsorbs the press material on the mold 601). In this state, the conveyor bar 65 is raised, and then the suction cup 70 is moved to the intermediate stand 74.
is moved to the right until it is directly above the . Thereafter, the conveyance bar 65 descends, and the suction M70 releases the pressed material held therein. Through this series of operations, the suction cup 70 sends the press material on the mold 60b one step to the intermediate stand 74. The above explanation has been made with the suction cup 70 as the upper limit, but the suction cup 71
．． 72.73 also moves in the same way as suction cup 70, adsorbing, @
By performing this movement, the press material on the intermediate table 74 is transferred onto the mold 611), the press material on the mold 61b is transferred onto the intermediate table 75, and the press material on the intermediate table 75 is transferred onto the mold 62b. transport to.

In this embodiment, if a conventional 1[0 feeding device is used in which a suction means is provided only for image feeding, the same feeding device is used between press machines 60 and 61, and between press machines 61 and 62. We had to place one unit at a time, but
By providing four arms on the transport bar, one transport device can transport the press material between three press machines.

In addition, in this example, the drive device 64 of the conveyance device 63 is arranged in the installation space designated for the press machine 61, so the space for the installation of the conveyance device 63 is specially set up between the press machines. Therefore, the distance between the presses can be narrowed to the necessary minimum, and the distance that the press material must be conveyed in one process is short, making it suitable for high-speed conveyance.

The press 61 is generally referred to as a gate press (it is preferable to refer to it as j).

Further, for example, in a press (62), where the conveyance bar 65 is stopped while being moved to the left, the conveyance bar 65 and the like do not get in the way, making it possible to perform single-shot operations.

Also, in FIG. 4, press Ij! By replacing 60 and 62 with the loading section and unloading section, respectively, the press machine 61 from the loading section of the press material
It is possible to carry out the process from loading to the unloading section to unloading by one conveyance device.

As explained above in Embodiment C, in the present invention, the suction means are arranged at equal intervals on the conveyor bar that moves vertically and horizontally, so that the numbers can be installed at three or more locations. The work of transporting workpieces between processing machines can be carried out using a small number of transport devices.

In addition, if the drive device of the If & feed device is housed within the installation space provided in the processing machine, the distance between the processing machines can be minimized, and the conveyance pressure of the workpiece to the next location is 1.
Since the fllll can be shortened and cut, it has the advantage of being suitable for high-speed conveyance.
