Description

TECHNICAL FIELD The present invention relates to a plate material stacking device, and more particularly to a plate material stacking device in which a plurality of material feeding roller units are arranged in the transport direction.

(Prior Art) Conventionally, for example, plate materials sheared by a shearing machine are conveyed backward by a belt conveyor and are dropped and accumulated on a collecting table arranged on the rear side of the belt conveyor.

In the above configuration, the upper surface of the plate material may be damaged when integrated.

Therefore, various stacking devices have been developed which do not damage the upper surface of the plate material when stacking the plate material.

(Problems to be solved by the invention) Among them, a plurality of left and right feeding rollers in a left-right direction orthogonal to the front-rear direction which is a conveyance direction of the plate material are provided in a cantilever manner, and a plurality of left and right feeding rollers are provided. In the plate material stacking device of the type in which the plate material is dropped by opening the center position in the left-right direction by separating from each other, the plate material stacking device is configured corresponding to the maximum length in the front-back direction of the plate material to be stacked. ,
Even in the case of stacking plate materials with a short length in the front-rear direction near the rear part, all the left and right material feeding rollers are configured to open the center parts on the left and right, so the plate material to be stacked next is located near the front part. Since it cannot be transferred onto the material-feeding roller in advance, there is a problem in improving the efficiency of stacking work of the plate materials.

(Means for Solving the Problems) In view of the conventional problems as described above, the present invention provides a plurality of sheet feeding roller units that perform a sheet feeding operation by arranging them in the front-back direction that is the sheet feeding direction. In order to support the plate material, a plurality of left and right material feeding rollers in the left-right direction orthogonal to the sheet material conveying direction are provided in a cantilever manner in each material feeding roller unit, and the plate material supported by each material feeding roller is A rear gauge for positioning the plate material in the front-back direction is provided so that each material-feeding roller unit is separated from each other in the left-right direction so as to be dropped, and the center position in the left-right direction is openable. The left and right material feeding rollers of each material feeding roller unit are provided so as to be movable and positioned in the front-rear direction.

(Embodiment) FIG. 1 is a front view of the plate material stacking apparatus 1 of the present invention viewed in the front-rear direction (Y-axis direction), which is the conveying direction of the product plate materials W, and is a vertically movable plate material stacker arranged in the lower center. The stand 3 (see FIGS. 4 and 5) is not shown.

The plate material accumulating apparatus 1 is provided with a machine frame 5 configured in a gate shape by appropriately combining shape steels and the like, and the lower surface of the beam member 7 in the left-right direction (X-axis direction) orthogonal to the conveying direction of the upper stage is provided. A rear gauge 15 is provided which is guided by left and right center beams 9 connected in the front-rear direction and is screwed into a lead screw 13 driven by an electric motor 11 so as to be movable and positionable in the front-rear direction.

Further, left and right side guide bases 21 which can be positioned on the center line 19 of the plate material stacking device 1 are provided across the intermediate cantilever beam 17 extending from both the left and right outer sides of the machine frame 5 to the center in a cantilever manner.

Inside the left and right side guide bases 21, left and right side guides 23, 23 for guiding the fall of the plate material W onto the plate material accumulating base 3 are provided, and on the upper surfaces of the left and right side guide bases 21, a plate material W described later is provided. A pressing stamper device 25 is provided as a centering device that presses both left and right outer edges to align with the center line 19.

Further, on the intermediate cantilever 17, driven by the left and right fluid pressure cylinders 27, guided by the intermediate cantilever 17 and moved toward and away from the center line 19 and positioned so that the center position is appropriately opened. For example, as shown in FIGS. 4 and 5, the material roller unit 29 is provided by being divided into a plurality of parts in the front-rear direction (conveyance direction).

A plurality of left and right material feeding rollers 31 protruding in the direction of the center line 19 through the material feeding roller unit 29 are provided in a cantilever manner, and an electric motor 33 provided above the material feeding roller unit 29.
As a result, the plurality of material feeding rollers 31 are simultaneously driven and rotated in the same direction via the belt 35.

The pressing stamper device 25 described above is a rotary actuator.
The swing arm plate 39 has a built-in 37, and is swingable between the above-mentioned cantilevered left and right material feeding rollers 31. Thus, the stamper plate 41 supported by the swing arm plate 39 is the left and right feeding rollers.
The left and right edges of the plate W loaded on the plate 31 are pressed so as to be aligned with the center line 19.

Next, the operation of the apparatus of this embodiment will be described with reference to FIGS.

As described above, the material feeding roller unit 29 of the plate material accumulating device 1 of the embodiment of the present invention is divided into three parts such as 29A, 29B and 29C in the front-rear direction. A plate material accumulating table 3 whose plate receiving surface can be raised and lowered over the entire length is provided under

First, if the front-back dimension of the carry-in plate material W is equal to or shorter than the same dimension of the rear material feeding roller unit 29A, the rear gauge 15 is arranged at a position corresponding to the length of the plate material W from the front gauge 43A.

FIG. 4 exemplifies a case where the plate material W accumulated in the rear material feeding roller unit 29A has substantially the same size as the length of the material feeding roller unit 29A.

The pair of material feeding roller units 29A, 29B, 29C are brought closer to the center line 19 position, the plate material W is carried in by the belt conveyor 45 (see FIG. 3), and the material feeding rollers 31 on the left and right of each roller unit are respectively fed. The six electric motors 33 are rotated to bring the tip of the plate material into contact with the rear gauge 15. Since the distance between the left and right side guides 23 provided inside the pair of left and right side guide bases 21 of the material feeding roller unit 29A is adjusted in advance to the horizontal dimension of the plate material W, when the pressing stamper device 25 as the centering device is operated, the plate material is activated. The horizontal center of W is aligned with the center line 19.

Provided on the front side (right side in FIGS. 4 and 5) of the rear gauge 15 is a non-contact sensor 47 that detects the approach of the tip of the plate W and controls the rotation of the material feeding roller 31.

The plate material stacking by the material feeding roller unit 29A has a function of lowering the height of the stacking table 3 by detecting with a stacking height detection sensor (not shown) every time the stacking height on the stacking table 3 becomes high to some extent. However, it is always lower than the rear gauge 15 at the height of the integrated top surface.

If the maximum allowable stacking height is reached and the stacking table 3 is not lowered further, or if the loading plate material W changes, the stacking at the rear material feeding roller unit 29A is stopped and the material feeding roller unit 29A is fed. The material rollers 31 are separated from each other and held in a state where the central position is opened, and the rear gauge 15 is moved to the central stacking position of the material feeding roller unit 29B on the front side thereof to return the stacking table 3 to the high position. (State of FIG. 5) When the dimension of the plate material W in the central material feeding roller unit 29B is shorter than the material feeding roller unit 29B, the rear gauge 15 of the central material feeding roller unit 29B is smaller than that of the central material feeding roller unit 29B as shown in FIG. The pair of opposing material feeding rollers 31 cannot go close to the center line 19 as they go inside. In this case, as shown in Fig. 1, the rear gauge
Although they approach and stop at a distance of 15 in the left-right direction, all the stacking work including the centering of the plate material W can be carried out in the same manner as in the material feeding roller unit 29A, and therefore redundant description will be omitted.

[Effects of the Invention] As will be understood from the above description of the embodiments, in short, the present invention provides a plurality of sheet feeding roller units (29A, 29B, 29C) for carrying the sheet material (W) with the sheet material ( W) are arranged in the front-rear direction, which is the conveyance direction, and a plurality of left and right feeding rollers (31) in the left-right direction orthogonal to the conveyance direction of the plate material (W) are provided to support the plate material (W). The material feeding roller units (29A, 29B, 29C) are provided in a cantilever manner, and each material feeding roller (31) is fed to drop the plate material (W) supported by each material feeding roller (31). A rear gauge (15) for positioning the plate material (W) in the front-rear direction is provided in each material feeding roller unit (each roller unit) so that each roller unit is individually separated from each other in the left-right direction so that the center position in the left-right direction can be opened. 29A,
29B, 29C) between the left and right material feeding rollers (31) is movable in the front-rear direction and positioned.

Therefore, when the sheet material W to be accumulated has a short dimension in the front-rear direction, when the sheet material is accumulated by the rear material feeding roller unit, the next sheet material is previously conveyed onto the front material feeding roller unit. Therefore, the work of accumulating the plate materials can be efficiently performed.
