Abstract

PURPOSE:To drop and mount a board material continuously on random mounting position, by forming a drive roller chip of a roller conveyor for carrying the board material rotatably and retreatably while facing with side guides of the conveyor. CONSTITUTION:A drive roller 2 for carrying a board material 21 is fixed through a rotary frame 3 to a side guide 1 and rotated by an engine 13 while advanced/backed in the direction (a) and (b) when rotating the frame 3 through a cylinder 8. With such structure when the stopper 17 is at the lowering position, the board material 21 is dropped and mounted on the mounting position A through repetition of advance/back of the drive roller 2, but when the stopper 17 is at the lifting position the board material 21 will pass over the mounting position A then dropped and mounted on the mounting position B automatically.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a continuous stacking device for plate materials that places plates continuously fed on a roller conveyor on a loading table.

Conventionally, as a continuous loading device for plate materials, side guides are arranged parallel to the conveying direction of the plate materials and facing each other, and rollers are attached to the side guides. An apparatus is known in which the rollers are opened laterally and the plate material 'a-PJ is dropped onto the platform.

In the above-mentioned loading device in which non-driving rollers are installed on the side guides, the conveyor or pinch rollers on the entry side are used to transfer the conveyance force to the plate material. was giving. For this reason, after the rear end of the plate passes from the conveyor or pinch roller, the conveyance force decreases due to the frictional resistance of the non-driven rollers, so it is possible to continuously move the plate to multiple loading positions at a fixed timing. It was not possible to load it. As a result, a package loading device with drive rollers was devised, but what about side guides with conventional drive rollers? The loading device has a complicated drive and rotation mechanism, and no device has been found that has two or more groups of rollers that allow the entire board to fall. For this reason, the conventional loading position of two or more items? Due to restrictions such as the long movement of the rotating frame, do you have to completely slow down the conveyance speed of the plate material or stop it before loading? There was no other option but to do it.

FIG. 1 shows an explanatory diagram of the conveyance state of a conventional continuous board stacking device, in which 2 is a drive roller and 21 is on an inlet conveyor 22.
Board material sent from arrow C → direction, 21A, 21BF
'i Laminated board material, A and B are loading positions. Drive roller 2
In this case, the loading position A consisting of the A1 group, the A2 group, and the A3 group rotates up and down at the same time, and the loading position B part rotates up and down separately from the loading position A part. To explain the entire loading condition at this time, the plate material 21ti is loaded at loading position B.
When the number of laminated plates 21B is one less than the predetermined number, the last one needs to be at the position indicated by the two-dot chain line 21b', and the next plate 21 is at the position indicated by the solid line 21a. think. In this state, the plate material 21 at the two-dot chain line 21b' position is dropped onto the laminated plate material 21B, and the plate material 21 at the solid line position 21a is dropped onto the laminated plate material 21A, and loaded.
Since it is possible to do 1, it is sufficient to lower all the rollers at loading position B and the rollers at loading position A at the timing when they each reach a predetermined loading position.

However, if the state of the plate material 21 at the solid line position 21b is completely grooved,
If the loading position A falls at a timing that is earlier than the loading position B, and the plate material 21 falls at F, then the plate material 21 at the solid line position 21b
will fall before reaching the predetermined loading position 21B. In order to completely improve this condition, it is sufficient to set the distance tt k between the solid line positions 21a and 21b and the distance t2 between the two-dot chain line 21b' and the solid line position 21a. To do this, (1) increase the difference between the speed of the inlet conveyor 22 and the speed of the drive roller 2, (2) completely reduce the speed of the inlet conveyor 22, or (3) reduce the speed of the inlet conveyor 22. There are three ways to stop it. However, with method (1), slipping scratches occur on the back surface of the plate material 21, and if the speed of the drive roller 2 increases, problems arise such as bending scratches when the stopper (not shown) collides with the plate material 21. . Methods (2) and (3) of decelerating or stopping the inlet low conveyor and guiding it only by drive rollers will directly lead to a decrease in the production volume of the equipment and a waste of power due to loss of acceleration/deceleration energy.

In order to solve this problem, the rollers of the A1 group and A2 group are fully lowered while maintaining the entire interval tl between the plates 21, and the plates 21 at the solid line position 21a are moved down completely. Dropped laminated board material 2
After the stacking of 1A is completed, if the plate material 21 is dropped onto the loading plate material 21B at the timing when it moves from the solid line position 21b to the two-dot chain line position 21b', continuous loading is possible without reducing the entry speed completely. . Note that the number of divisions of the rollers in the loading position A portion is determined by the length of the plate material 21, the entry speed, and the conveyance speed.

The present invention has been made in view of the above-mentioned situation, and is a continuous loading device for plate materials that can continuously and reliably guide and load plate materials to any loading position without reducing the conveyance speed of the plate materials. It is bound for the purpose of providing.

The continuous stacking device for plate materials of the present invention includes side guides that are disposed opposite to each other in parallel to the conveyance direction of the plate materials that are continuously fed on the roller conveyor, and side guides that support both side ends of the plate materials and A plurality of rotary frames each having a plurality of drive rollers formed opposite to each other so as to be rotatably attached to the guide (5) and rotated to cause the plate material to fall; A plurality of loading tables on which plates are dropped are provided, and a stopper for selectively stopping the advancement of the plates is provided at each loading platform position.

An embodiment of the continuous loading device for plate materials of the present invention will be described below with reference to FIGS. 2 to 4, in which the same parts as in FIG. 1 are denoted by the same reference numerals. Figure 2 is a side view, Figure 3 is a detailed view of part 0 in Figure 2,
FIG. 4 is a cross-sectional view of a 1/2 portion taken along the line N--N in FIG. On the main frame 14 fixed on the foundation, side guides 1 extending in the direction of movement of the plate 21 and facing each other and formed to match the width of the plate 21 are fixed on both sides.

The side guide 1 has the length of the board 21 and the entrance conveyor 22.
A plurality of rotating frames 3 corresponding to the number of divisions determined by the speed of the driving roller 2 are rotatably supported on a rotating pedestal 9. One or more drive rollers 2 are rotatably supported on the rotating frame 3, and the drive rollers 2 are connected to a distribution gear box 6.
Sprocket wheel 4 driven by a gear (not shown)
a, Cheno 51 It is driven through a sprocket wheel 4b attached to the rotating frame 3, and five chinos. The distribution gear box 6 includes a motor 13 attached to the rear end of the side guide 1, a main reduction gear 12, and a universal joint 7.
It is designed to be driven through.

Also, the rotating frame 3Vi is connected to the cylinder 8 attached to the side guide 1 through 10 trunnion fittings and the trunnion fitting 1.10, and the operation of the cylinder 8 moves the cylinder 8 in the direction of arrows (a) and (b) in FIG. It is designed to be rotationally driven. Therefore, the driving roller 2 rotates as a unit as shown by the two-dot chain line by the operation of the rotating frame 3.
Is the plate 21 supported when the two-dot chain line position is reached? It is designed to be released and the plate material 21 is allowed to fall. In addition, 11 is a connecting metal fitting. Reference numeral 15 denotes an inlet stopper cart, and 16 an outlet stopper cart, each of which has an inlet stopper 17 and an outlet stopper 1.
Eight pieces are hung and fixed so that the top of the king frame 14 can be adjusted to the length of the plate material 21 so as to be movable back and forth. And the entry side stopper 17 plate material 21? In order to pass to the loading position B, the stopper cylinder 19 is configured to be movable up and down. 20 is a loading platform.

In the above continuous loading device, the inlet roller conveyor 22
The plate material 21 that is being conveyed is received by the drive roller 2 that is rotationally driven by the prime mover 13, and at a predetermined loading position A, the cylinders 8 of the A1 group and the A2 group are operated, and the rotating frame 3 is rotated by the arrow (I). ), the front end is stopped and guided by the entrance stopper 17 on the loading table 20, and is dropped and loaded.

Subsequently, the drive roller 2 is driven to rotate in the direction of the arrow (B), and the new plate material 21 is taken up and this operation is repeated one after another.

Completion of loading a predetermined number of plates 21 at the loading position A is detected by a sheet number counter or the like (not shown), and the entry side stopper 17 is raised via the stopper cylinder 19 and placed on standby. The new plate material 21 that continues to be sent passes through the loading position Ak and is sent to the loading position B, and at a predetermined position, the rotating frame 3 only at the loading position B is moved to the cylinder 8? The sample is then rotated and dropped onto the loading table 20 at the loading position B. Then, it detects that the predetermined number of sheets at loading position B is one less, and also detects the passage of the plate material 21 sent to loading position B, lowers the entry side stopper 17, and starts loading at loading position A. . Under the driving conditions in this state, A3
Since no operation command is given to the rotating frame 3Vi and cylinder 8 of the group, the entire raised position is maintained.

Since the continuous plate material loading device of this embodiment is configured in this way, it is possible to smoothly transfer continuously fed plate materials to a plurality of loading positions alternately by a predetermined number without reducing the conveyance speed. It is possible to guide and load continuously and reliably. The plate material is guided to a predetermined position by the drive roller at an appropriate speed. In addition, the board materials sent from the inlet conveyor are stacked, for example, by instructions from an inspection device, such that first-class board materials are stacked at loading position A, and second-class board materials are stacked at loading position B, either continuously or discontinuously. It is also possible to separate. Furthermore, even if the lengths of the plates are different (9), continuous work sessions can be switched by simply changing the positions of the stopper carts at loading positions A and B. Furthermore, the device is simpler than before, and unlike the conventional drive that uses a friction wheel, etc., the drive roller is directly driven through the drive roller, so the number of rotations of the drive roller in the front and rear directions is perfectly matched. This eliminates the bumps that occur when the plate material transfers over the rollers, and also prevents the rollers from being scratched.

As described above, the continuous board loading device of the present invention can continuously and reliably load boards at any loading position without reducing the transport speed of the board. It has the effect of guiding and loading.
