Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a girder for loading quadrilateral plate-like bodies made of metal, plywood, synthetic resin, etc. This invention relates to a piler for stacking plate-shaped bodies that are brought together and conveyed.

FIG. 1 shows a simplified plan view of a conventional piler installed after a so-called hot shear line for cutting steel sheets having a thickness of less than about 6 mm.

Metal sheet 1 of fixed length: Well, it is placed approximately in the center of the belt conveyor 2, conveyed in the advancing direction of the arrow 3, and stacked in the piler shown in the figure. The distance between the pair of side guides 6 and 7 supported across the crossbeams 4 and 5 is determined in accordance with the width of the sheet 1. Further, the distance between the fixed backstop section 8 and the end stop section 9 is determined corresponding to the length of the seat. The end stop member 9 is supported on its back by a shock absorber (not shown) and is attached to an end stop frame 11 supported by a fixed frame girder 101. In order to change the interval between the side guides 6 and 7, a threaded portion 1 having screw threads formed in opposite directions to each other.
A combination of a pair of threaded rods 12, 13 and a nut threaded onto each threaded portion is used. By the synchronous rotation of the threaded rods 12, 13, the side guides 6, 7 are moved toward or away from each other by equal distances in the width direction of the seat, so that the end stop member 9 is always located in the center of the side guides 6, 7. During conveyance, the sheet 1 having a thickness of less than 6 inches may come off the center of the belt conveyor 2 and hit the expanded front end portions of the side guides 6 and 7.

Even in this case, the front end portions of the side guides 6 and 7 guide the sheet to correct its traveling direction, and the sheet is piled while being centered, which is convenient. However, in plate rolling equipment and plate acid cutting equipment where the sheet thickness exceeds about 6 sides and extends from 9 sides to 25 sides or more,
Since it is difficult to convey sheets using a belt conveyor both in terms of capacity and mechanism, a roller table is used.

In this case, it is almost impossible to pass the heavy sheet 1 through the center of the roller table. Even if the Yoshiba sheet 1 could be run in the center of the roller table, the side guides 6 and 7, which are separated slightly wider than the sheet width,
The entry of the sheet into the space must be precise. Otherwise, the seat with a large inertia force will collide with the front ends of the side guides 6 and 7 and stop, which will force the work of the cutting process line to be interrupted, and there is a risk that the equipment will be damaged. There is. In the prior art shown in the second figure, in order to solve this problem, a skew-shaped roller table 14 is used to move the sheet closer to a guide wall 15 extending along the conveyance direction.

In this plank sheet pira, one side guide 16
is fixed, and the other side guide 17 is displaced by a screw movement depending on the width of the seat. The end stop member 18 is centered between the side guides 16, 17 by a screw movement. Each drive source for displacing the side guide 17 and the end stop section 18 is installed individually and independently. Therefore, when sheets 1 of different widths are conveyed to the mirror, the operator operates each drive source with sufficient care so that the movable side guide 17 and the end stop member 18 do not collide, and moves the side guides 16 and 17. must be adjusted. For example, in order to narrow the space between the side guides 16 and 17, the end stop member 18 must first be moved toward the fixed side guide 16, and then the movable side guide 17 must be moved. On the other hand, if the distance between the side guides 16 and 17 is to be widened, the end stop member 18 must be moved after the movable side guide 17 has been operated. This order of operations relies on the operator's memory, which places a heavy burden on the operator. Further, the end stop member 18 must be positioned in the center between the side guides 16 and 17 by the operator's operation as described above.

If it is not positioned in the center, Q} When the seat collides with the end stop member 18, an irregular force will be applied to the end stop member 18, and the seat will not fall smoothly to the pillar, and ■ the side guide 16, 17 and the backstop member 18, a large force is generated locally, inducing severe vibration. {4' This results in an increase in noise, '5} The alternating shock given by the seats is especially severe between the backstop 8 and the end stop member 18, and {6) It is impossible to pile the four sides of a plurality of seats correctly aligned.
The present invention has been made in view of the above-mentioned drawbacks, and has an end stop member that is automatically positioned in the center between the fixed side guide and the movable side guide according to the displacement of the movable side guide and is placed on standby. The object of the present invention is to provide a Pyramid with a similar structure, thereby overcoming the above-mentioned drawbacks. FIG. 3 shows a plan view of one embodiment of the present invention, and FIG. 4 shows a simplified cross section taken along the cross-sectional view WW in FIG. 3.

A thick plate sheet cut to a regular length into a rectangular shape is conveyed by a skew-shaped roller table 14, and is conveyed by a pinch roller 21.
After that, the Pyra will be entered into. The skew-shaped roller table 14 conveys the sheet by moving one side edge of the sheet parallel to the conveyance entry direction (arrow 3) along the guide wall 15, and is well known to those skilled in the art. In Pira, the fixed side guides 16 and the movable side guides 17 align both side edges of the sheet 1 parallel to the advancing direction 3, and the fixed backstop member 8 aligns the lower back green in the advancing direction 3 of the sheet 1. The end stop section 20' aligns the upper front green with respect to the direction of entry 3 of the sheet 1, and in this way these members 16, 17, 18,
201 defines the loading space of the sheet turtle.

The sheets 1 are stacked on a pedestal 24 attached to a lift device 23. The fixed side guides 16 are fixed to the cross beams 4 and 5.

The movable side guide 17 is supported by the machine girders 4 and 5 via wheels, and a screw mechanism consisting of a pair of threaded rods 26 and 27 and a nut, which are driven by a drive source 25 to rotate synchronously, rotates the movable side guide 17 between the seats. The displacement is adjusted in a direction perpendicular to the approach direction 3. The end stop member 2 is formed into a plate shape and has a Z configuration, and is supported by a moving base 29 by a pin 28, and a shock absorber 301 attached to the moving base 29 at the position where the front of the seat collides with the back support. be done.

The end stop frame 11 is an end stop member 20
The wheels 31 of the movable base 29 allow the Z-end stop member 20 to be displaced in the direction perpendicular to the seat entry direction 3 between the side guides 16 and 17. The end stop frame 11 straddles both side guides 16 and 17, and has wheels 2 on top of the fixed frame girder 10.
32. The fixed frame girder 1 is disposed on the outside of both side guides 16 and 17. Racks 33, 34 are provided on the upper part of the fixed frame girder 10, and these racks 33, 3
The pinions 35 and 36 that mesh with the seat 4 are rotationally driven by a 2 drive source 37 (see FIG. 4) equipped on the end stop frame 11, and thereby the end stop frame 11 is adjusted to be displaced parallel to the seat entry direction 3. Ru. Note that for convenience of illustration, the drive source 37 and the like are omitted in FIG. 3. Guide rails 40 and 41 equipped with idler rollers 38 and 39 are provided on the three side guides 16 and 17 so as to be movable forward and backward toward the loading space of the seats. These guide rails 40,4
1 is moved forward and backward by driving links 45 and 46 by drive sources 43 and 44 that are interlocked by equalizer shaft 42. When sheet 1 is conveyed from roller table 14 with guide rails 40 and 41 protruding into the sheet loading space, sheet 1
is the end stop member 2 on the idler rollers 38 and 39.
Proceed until you collide with 0'.

At the time of the collision, the guide rails 40, 41 are moved by the drive sources 43, 4.
4, the sheet 1 is retreated from the sheet loading space and dropped onto the pedestal 24. Back up and guide rails 40, 41
returns to its original protruding position and prepares for the next sheet 1 to enter. Referring to FIG. 5, the principle of the shark construction according to the invention is shown, which allows the end stop member 20 to always be centered between the side guides 16, 17.

The end stop frame 11 is provided with a pair of sprocket wheels 50 having a rotation axis parallel to the seat entry direction 3.
, 51 are pivotally supported. sprocket wheel 60,51
In between, an endless chain 53 whose both ends are connected to the movable piece 52 is stretched in a direction perpendicular to the sheet entry direction 3. A displacement range of the movable side guide 17 exists within the distance between the sprocket wheels 50 and 51.
A sprocket wheel 54 that rotates coaxially and integrally with one sprocket wheel 50 is pivotally supported by the end stop frame 11. A chain 56 extending perpendicularly to the sheet advancing direction 3 is wound between this sprocket wheel 54 and another sprocket wheel 55, and this chain 56 is connected to the movable table 29 so as to have an endless shape. The distance between the axes of the sprocket wheels 54 and 55 covers the range in which the end stop member 20 moves in response to the displacement of the movable side guide 17. What is important is that the diameter of the pitch circle of sprocket wheel 64 is 1/2 the diameter of the pitch circle of sprocket wheel 50 coaxial therewith. Therefore, the end stop member 20 and the movable table 29 are displaced by 1'2 of the displacement amount of the movable piece 52 in the same direction as the displacement direction of the movable piece 52. A longitudinal guide groove 60 extending horizontally and parallel to the sheet entry direction 3 is fixedly provided on the upper part of the moving side guide 17 .

The length of the guide groove 60 is selected to include a range in which the end stop member 20 is displaced and adjusted in parallel to the sheet entry direction 3 in accordance with the length of the sheet entering the sheet.
Referring to FIG. 6, an enlarged view of a portion of the movable piece 52 in FIG. A roller 61 having a vertical axis of rotation is guided by the guide groove 60 and rolls, and this roller 61 is supported by the moving piece 52. The moving piece 52 is a roller 62
, 63 along the end stop frame 11 at right angles to the sheet entry direction 3. Coro 6
1 is parallel to the guide groove 601, the movable piece 52 can only be displaced along the guide groove 60' in parallel to the advancing direction 3 of the sheet 1; Relative displacement between the moving piece 52 and the guide groove 60 is prevented. Therefore, even when the end stop frame 11 is displaced parallel to the sheet advancing direction 3 and the movable side guide 17 is displaced perpendicular to the sheet advancing direction 3, the movable piece 52 is moved by the amount of displacement of the movable side guide 17. can be transmitted to the chain 53. In this way, the end stop member 20 and the movable table 29 are set in advance at the center between the side guides 16 and 17, so that the end stop member 20 and the movable base 29 are always moved regardless of the displacement of the end stop frame li and the movable side guide 17. The platform 29 can be centrally located between the two side guides 16, 17. In other embodiments of the invention, instead of the chain transmission, other chain transmissions may be used. .

Further, a combination of two pinions having a pitch circle of 1'2 and two racks that mesh with these pinions, respectively, may be used. Also, roller tables other than skewed roller tables may be used. As described above, according to the present invention, the end stop member is automatically positioned and placed on standby in the center between the fixed side guide and the movable side guide according to the displacement of the movable side guide. The operator's operation is extremely easy and simple, and there is no risk of operator error, which greatly contributes to labor savings.

Moreover, since the structure of the present invention is relatively simple, it can be widely implemented in conjunction with existing pilasters.
