In a bar-stacking type work stacking device that lifts the whole work so that the work located in the next layer comes to the position of the uppermost layer every time, a bar stacking platform suitable for the work of a desired size is supported by a guide device. An exposure, characterized in that it is provided movably on a table, and provided with a bar stack positioning device for automatically fixing the bar stack when the bar stack reaches a predetermined position on the support table. Bar stacking type work loading device for equipment.

(2) The rod-stacking type work stacking apparatus for an exposure apparatus according to (1), wherein the diameter of the guide rod is set to be slightly smaller than the diameter of the positioning hole of the work fitted to the guide rod.

[Action]

[I] Since the bar stack is movably mounted on the support table having the guide device, the lifting device is not required, and the device can be simplified.

[Ii] Since the bar stack positioning device is provided, the bar stack positioning operation can be performed easily and accurately, and the bar stack replacement operation is easy.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.
Regarding the reference numerals and symbols in the drawings, the same reference numerals and symbols are given to the same portions as the respective structural portions when the conventional technique is described.

FIGS. 1 to 4 show a first embodiment of the present invention. The main part of the apparatus of this embodiment is such that the interval between guide rods 1, 1 and the plane shape are adapted to a work 2 of a desired size. The bar stack 32 configured as above, a pair of guide rails 33 and 33 with stoppers mounted on the support 20, and two sets of bar stack positioning devices 34 and 34 (see FIG. 3), etc. Guide rod 1,1
In order to facilitate the detachment of the work 2, the diameter thereof is formed to be slightly smaller than that of the work positioning holes 3, 3. The pair of guide rails 33, 33 are each made of an L-shaped mold material, and are arranged so as to intersect at right angles with the conveyance direction of the work 2.

A required number (four in the figure) of casters (or wheels) 31,31,31,31 are attached to the bottom surface of the bar stack 32, and each caster 31 has its inner portion inside the pair of guide rails. It is adapted to roll on the support base 20 while sliding on the outer side of 31,31. Further, the inner size of the hole 35 of the bar stack is set to be sufficiently large with respect to the outer size of the bar 9 so that the bar 9 can be lifted up through the center of the bar where the bar 9 is positioned. .

In the two sets of positioning devices 34, 34, a bar stack of a desired size travels along the guide rails 31, 31 on the support base 20,
A predetermined position on the support 20, that is, two guide bars 1,1 standing on a bar stack 32 as shown in FIG. 1, connect a pair of positioning pins 36,36 provided in the exposure unit 11. When it reaches the extension line 37 of the line, it serves to automatically fix the bar stack 32 at that position, and this device is attached to the lower surface of the support base 20 as shown in FIG. The casing 38, a compression spring 39 arranged inside the casing 38, and a positioning pin 40 or the like that is constantly urged upward by the compression spring 39, and when the rod stack 32 reaches the predetermined position, The pin 40 is fitted into a positioning hole 42 (see FIG. 4) provided in the bar stack 32 to automatically fix the bar stack 32.

On the other hand, in the exposure unit 11, the set of positioning pins 36, 36 already described is arranged on one side of the transparent plate 12 of the lower baking frame 13 and in parallel to the transfer line 43 of the transfer device 5. The diameter of the positioning pins 36, 36 is such that the positioning pins 36, 36 are fitted into the positioning holes 3, 3 of the work 2 without any gaps in order to accurately position the work 2.

Although not shown here, a required number of pins (not shown) for positioning a work of another size are provided on the line connecting the pins 36 and 36, and these pins 36, 36 ... Both of them are selectively driven by a known hydraulic cylinder device (not shown), and project above the transparent plate 12 or retract below the transparent plate 12 as required.

The handling procedure and operation of the apparatus of the present embodiment will be described below. Now, in order to mount the bar stack 32 of a desired size on the support table 20, an operator lifts the bar stack 32 and the support table
The rod stack 32 is placed on the support 20, and is run on the support 20 along the guide rails 33, 33. Then, when the bar stack 32 reaches the above-mentioned predetermined position, the bar stack positioning devices 34, 34 are actuated to automatically insert the pins 40, 40 into the holes 42, 42 to set the bar stack 32 to the predetermined position. Position in position.

The bar stack 32 having the casters 41 is attached to the guide rails 33, 3
Since it is moved on the supporting table 20 having 3 and is automatically positioned by using the positioning devices 34, 34, the conventional lifting device is not required, the device is simplified, and the work of exchanging the bar stacks can be performed. It's easy.

A second embodiment of the present invention is shown in FIGS. 5 and 6. In this example, a required number of guide rollers 45, 45, 45 ... Are provided in place of the guide rails 13, 13 shown in FIG. 1, and the bar stack 32 is moved along the guide rollers, and at the same time, a support base is provided. A stopper (not shown) is provided at an appropriate position on 20. Other than this, there is no difference from the first embodiment.

It should be noted that the present invention is not limited to the above-described embodiments, and it goes without saying that various modifications are made without departing from the gist of the present invention.

[Effect of device]

As described above, the present invention exhibits the following excellent effects.

[I] Since the bar stack suitable for the size of the work is movably mounted on the support base having the guide device, it is not necessary to provide a lifting device as in the conventional case, and the device can be simplified.

[Ii] Since the bar stack positioning device is provided, the bar stack can be positioned easily and accurately, and the work of exchanging the bar stack is easy.

[Iii] Since the fitting tolerance between the guide rod of the bar stack and the positioning hole for the work is loose, the work can be smoothly separated from the guide rod.
