Abstract

PURPOSE:To change work stages efficiently and facilitate positioning of a work by disposing a plurality of transport conveyers with the respective ends thereof facing a carry-out space provided with an adjust table for turning and elevating a work and a relay conveyer. CONSTITUTION:Works placed on the first transport conveyer 3 are carried in a carry-out space A through an adjust table 7 and a relay conveyer 6. At this time, with belt conveyer 6A lowered, the works are sequentially carried out to a working machine 11 by carry-out means 2. The work W is turned by rotation of the adjust table 7 and reversing of conveyers 6a, 6B to change the position of the work. In case of replacing the works W, the work W in the carry-out space A is carried out to the second transport conveyer 4 by the belt conveyer 6A, and the next work is carried in the carry-out space A by the first transport conveyer 3. The ghird conveyer 3 is similarly used. In this arrangement, the work stages can be changed efficiently and positioning of the work can be facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to a workpiece take-out device that includes first and second 1ull conveyors and is capable of streamlining workpiece take-out work.

[Background technology]

In order to take out workpieces such as stacked original plates one by one, conventionally, for example, the workpieces are placed on a free-roller container, the workpieces are extended into the takeout space, and then the workpieces are taken out using a general takeout tool. However, it is often necessary to change the type of workpiece depending on the product.

In such a case, with the workpiece take-out device using the Free iJ-La conveyor mentioned above, it is necessary to return the unnecessary workpiece to the carry-in position and then change the type of workpiece, which takes a lot of time and effort. required.

Furthermore, if the delivery tool is equipped with a vacuum suction tool, the direction and position of the work must be adjusted correctly, and therefore (careful positioning is required when placing it on the fastest conveyor). There were also some drawbacks.

[Purpose of the invention]

The present invention is based on the use of first and second transport conveyors, and aims to provide a workpiece take-out device that can streamline workpiece changeover and solve the above-mentioned problems.

[Disclosure of the invention]

An embodiment of the present invention will be described below based on the drawings.

In the figure, the workpiece take-out device 1 has first and second 1-ift conveyors 3.4 arranged with their respective ends facing in a carry-out space A above which the carry-out tool 2 is installed, and Space A is provided with a relay conveyor 6 and an adjustment table 7.

The carrying out tool 2 is a processing machine 11 that performs various processing on the workpiece W.
A traveling platform 17 that moves across the processing machine 11 and the carrying out space A is attached to the upper end of the pillars 15 provided on both sides of the processing machine 11 and a rail 16 extending toward the carrying out space. Note that the traveling table 17 has a cylinder 19 on its upper surface, and a suction tool 2 is attached to the traveling table 17.
It is possible to raise and lower the lifting platform 21 with a height of 0.20 mm.

Said first! 'i'S2's transport competition 1/3.4 is
It consists of a pair of belt conveyors A that have a gap G and whose ends face each end of the carry-out space A, and the first and second conveyors 3 and 4 have a side surface facing the carry-out space and a front face thereof. The two ends are orthogonal to each other by being arranged with their ends facing each other. Further, in this embodiment, a third conveyor 5 is provided on the other side of the carry-out space A, with its end facing the third conveyor 5 in line with the first conveyor 3. Note that the third conveyor conveyor 1-5 also uses a pair of belt conveyors 5Δ and 5A. The adjustment table 7 has four corners, that is, bells 1, 3A, 3A, 3A, 3A, 3A, 3A,
and the center lines of the belt conveyors 4A, 4A intersect with each other. This adjustment table 7 has a bottom plate 23 and a top plate 2.
4, and is formed to be extendable and retractable, and for example, four ball holders 25 are attached to the upper surface thereof. The ball holder 25, the spherical body 26, and the holder 27 that supports the spherical body 26.
and is attached to the lower surface of the upper plate 24 so that the top of the sphere 26 protrudes from the upper tli 24. Further, the adjustment table 7- moves up and down the third conveyor 3, 4, 5 by expanding and contracting, centering on a position equal to the upper surface of the adjustment table 7-.

The relay conveyor 6 includes a pair of navy blue bells 1<z belts 6A, 6A connecting between the a and the bases, and a horizontal bell [conveyor 6B, 6B, which connects the belt conveyors 6A, 6B in the horizontal direction. 6B includes a height that is flush with the first to third conveyors 3, 4, and 5. Go up and down.

However, the workpiece take-out device 1 uses, for example, a forklift or the like to place M stacked M workspieces W on a pallet P on the first conveyor 3, with the top surfaces flush with each other. It passes through the adjusted adjustment table 7 and relay conveyor 6 and is carried into the carrying-out space A. The belt conveyor 6A is lowered. Further, the work W is sequentially carried out to the processing machine 11 by the carry-out tool 2. In addition, in the carry-out space A, the workpiece W is rotated using the adjustment table 7, or the workpiece W is rotated using the belt conveyor 6A1.
By running the bells 6, 6, 1, and conveyors 6B, 6B in opposite directions, the workpieces W are rotated and their orientations are aligned. Moreover, the positional deviation in the front, back, left, and right directions can be adjusted by the belt conveyors 1, 68, and 6B.

Next time when a workpiece W of the same type is required, the workpiece W in the carry-out space is transferred to belt competitions 1 and 6.

A and 6A are driven and carried out to the second conveyor 4. Further, prior to carrying out the work, the next work W is placed on the first conveyor 3 in advance, so that the necessary work W can be carried into the carry-out space at the same time as being carried out.

Furthermore, by using the third conveyor 5, more types of workpieces W can be placed in advance.

[Effect of idea]

As mentioned above (the workpiece take-out device of the present invention has first and second conveyors disposed in the carry-out space with their ends facing each other, and a relay conveyor and an adjustment table are provided in the carry-out space). This makes it extremely convenient to change workpiece setups, and
Positioning and angle adjustment in the unloading space are possible, and the workpiece unloading efficiency can be greatly improved, among other effects.

In addition, in the apparatus of the present invention, the work can be taken out by a gripping device equipped with gripping claws instead of a suction tool as a till extractor, and a chain conveyor or even a driven roller conveyor can be used instead of a belt conveyor. It can be transformed into various forms.
