Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The plate-like material loading apparatus of the present invention is used for stacking plate-like objects such as plate materials to be transferred with their tips aligned, and in particular, two or more plates are arranged in the width direction. It is suitable for stacking plates to be transferred.

[0002]

2. Description of the Related Art A typical example of this type of plate-like material loading apparatus is shown in FIGS. Among them, the plate-like object loading device shown in FIG. 3 transfers the plate-like object A transferred by a conveyor B while sandwiching it between delivery rollers C facing each other vertically and rotating at a predetermined speed while accelerating. The second plate-like object A is stacked on top of the plate-like object A which has already been stacked downward by discharging in the forward direction and causing the tip of the plate-like object A to abut against the abutment body D by its flight. It is a thing. By the way, in this stacking device, there is no problem with the width of the plate-like object as long as it is within the width of the feed roller, and if it is within the width of the roller, the plate-like objects can be transferred and stacked side by side in the width direction. ..

In the plate-like material loading apparatus shown in FIG. 4, the plate-like material transferred by a conveyor or the like is placed on two linear guides F with rollers facing each other via a conveying roller E, and the plate-like material A is placed. When the bumps hit the abutting body D, the respective linear guides F with rollers are retreated to the outer sides in the width direction of the plate-like object A by actuators G such as cylinders, and the plate-like object A is dropped downward. The next plate-shaped material A is stacked on the plate-shaped material A stacked below.

[0004]

However, among the conventional loading devices for plate-like objects shown in FIG. 3, the plate-like object to be loaded and the plate-like objects already loaded are rubbed or bumped against each other. Therefore, there is a problem that the surface of a plate-like object such as a decorative board material having a smooth finish attached to the surface or a painted board material having a coating is scratched or the coating is peeled off. Moreover, since the tip end of the plate-like object is abutted against the abutment body by the flight of the plate-like objects, the stacking state is likely to vary, and on the contrary, it takes a lot of man-hours to arrange them.

Further, in the plate-like object loading device of FIG. 4, since the plate-like objects must be placed on the linear guides with the rollers facing each other, the width of the plate-like objects is limited, and at the same time, two or more plate-like objects are provided. It is also not possible to transfer and load side by side. Also, it is troublesome to match the movement timing of the linear guide with rollers and the transfer speed of the plate-like object, and since the movement is performed by an actuator such as a cylinder, the operation of the actuator is slow, for example, in the cold season. In such a case, the timing could not be matched, and the apparatus often stopped.

The present invention has been developed in view of the above problems, and it is possible to stack two or more plate-like objects side by side because there are few restrictions in the width direction of the plate-like object and to damage the plate-like object. In addition, the present invention provides a plate-like object loading device that can surely load the ends with their ends aligned.

[0007]

SUMMARY OF THE INVENTION A plate-like object loading apparatus according to the present invention is a plate-like object loading apparatus for stacking plate-like objects that are transferred horizontally or at an angle close to this, with the tips in the transfer direction aligned. Two or more juxtaposed at a distance wider than the maximum width of the plate-like object to be moved and moving at a constant speed in the transport direction of the plate-like object, and adjacent adjoining ropes at appropriate intervals in the longitudinal direction of the rope. A support tool that is passed between the strips, a transport roller that is provided on the front side in the transport direction of the plate-like object and that is rotated in the transport direction of the plate-like object at the same speed as the rope, and at least from the transport roller to the plate-like shape. It is characterized in that it is provided with a stopper which is provided ahead of the plate-like object in the transfer direction by a distance of not less than the length of the object and which a plate-like object to be transferred, which is carried on the support tool and the conveying roller, abuts.

[0008]

In the plate-like object loading apparatus of the present invention, when the plate-like object is sent out from the conveying roller provided on the front side in the transfer direction onto the support tool which is passed between the adjacent ropes, the plate-like object is moved. The plate-like object is transferred forward with the tip of the object resting on the support. When the tip of the plate-like object hits the stopper in due course, the stopper is separated from the conveying roller by the length of the plate-like object or more, so that the rear end portion of the plate-like object in the transfer direction falls off the conveying roller and falls downward. To do. When the cord moves further, the supporting tool is disengaged from the front end portion of the plate material in the transfer direction in a state where the plate material hits the stopper, and the front end portion also drops downward.
At this time, since the moving speed of the cords and the supporting tool is equal to the rotating speed of the carrying roller, the plate-like object does not rub anywhere. Further, after the rear end of the plate-like object in the transfer direction falls downward, the support tool is disengaged from the front end of the plate-like object in the transfer direction with the tip of the plate-like object abutting against the stopper, and the tip part is removed. Since it falls downward, there is little deviation of the tip and it is easy to align automatically.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of a plate-like material loading apparatus according to the present invention, which is arranged side by side on a conveyor B or the like and is indicated by an arrow z
It is used to load the plate material A, which is transported in the direction (horizontal direction) and divided into two in the width direction, with the leading ends aligned. Note that the tips of the two sheet materials A to be transferred are actually slightly displaced as shown in the figure.

A main chain 1, which is a cord, is provided on both sides of the main body frame (not shown) in the transfer direction of the plate members A at intervals wider than the maximum width of the two plate members A. Each main chain 1 is arranged in a substantially rectangular shape in the longitudinal direction via four sprockets 10. Opposing sprockets 10 of both main chains 1 are connected by a connecting shaft 11, one of which is another sprocket. 12 is attached, and the driving force of the motor 13 is attached to the sprocket 12 via a belt 14, a gear reduction device 15, etc.
Transmitted by. This causes both main chains 1 to move at a constant speed relative to each other.

Two round bars 2, which are support members, are provided on both main chains 1 at appropriate intervals. The round bar 2 is for mounting the tip of the plate material A to be transferred, and the reason why the round bar 2 is used as a supporting tool is to prevent the plate material A mounted thereon from being damaged as much as possible. In addition, between the main chains 1 on the front side of the main body frame in the transfer direction of the plate material A, the conveyance roller 3 is provided.
Is provided. The carrying roller 3 sends the plate material A placed on the round bar at the same speed as the main chain 1.
Another sprocket 17 is attached to one of the sprockets 10 of the main chain 1, and via a chain 19 different from the sprocket 18 attached to the conveying roller 3,
It is designed to rotate at the same speed as the main chain 1. In addition,
In this embodiment, the conveying roller 3 is provided slightly below the moving range so that the round bar 2 passes over the conveying roller 3. Further, the conveying roller 3 can be slid in the transfer direction of the plate A according to the length of the plate A and can be fixed at a desired position.

Stoppers 4 are provided above both main chains 1 ahead of the plate material A in the main body frame in the transfer direction. The stopper 4 is mounted on the round bar 2 and is conveyed by the conveying roller 3
The plate material A sent by is abutted, and the upper part thereof is formed curved or slanted toward the rear in the transfer direction of the plate material A for the reason described later. This stopper 4
Is provided so as to be separated from the conveying roller 3 by at least the length of the plate material A. Below the stopper 4, a guide plate 20 for guiding the tip of the falling plate A is provided at a distance corresponding to the passage of the round bar 2.

A support plate 21 is provided on the side of the guide plate 20 on the left side in the transfer direction of the plate material A shown in the figure, and two pressing devices 22 are provided at the opposite positions. The pressing device 22 is composed of a cylinder 23 and an abutting plate 24 attached to the push rod thereof, and expands and contracts toward the support plate 21 side by hydraulic pressure from a hydraulic unit (not shown).

Below the support plate 21 and the guide plate 20, a lifter 25 for moving the stacked plate materials A in the vertical direction is provided. This lifter 25 is an existing one, for example, as shown in the figure, is provided with a lower support base 26 and an upper loading base 27, which are connected by an X-shaped link arm 28, one of which is a link arm 28. Cylinder 2
9 are serially installed. In this lifter 25, when the cylinder 29 is expanded and contracted, the loading table 27 moves up and down in parallel with the rotation of the link arm 28.

On the conveyor B, a start limit switch 30 for detecting the plate material A to obtain an operation start signal of the loading apparatus is provided, and the lifter 2 is provided from the guide plate 20.
The arm 31a of the elevating limit switch 31 for obtaining the elevating signal of 5 is projected, and the stop limit switch 32 for detecting the round bar 2 to obtain the stop signal of the present stacking device is provided behind the guide plate 20. The signals are output to a control panel (not shown).

The operation of the loading device will be described below. First, as shown in FIG. 2a, when the round bar 2 is in contact with the stop limit switch 32, the main chain 1 and the carrying roller 3 are stopped, and the next round bar 2 is located slightly ahead of the carrying roller 3. ing. From this state, when the plate material A conveyed on the conveyor B comes into contact with the start limit switch 30 and the signal is output to the control panel, the main chain 1 causes the arrow y to move after a suitable time by the timer in the control panel. The transport roller 3 rotates in the arrow x direction at the same time. As a result, as shown in FIG. 2B, the plate material A is sent out from the carrying roller 3 and further forward in the transfer direction with its tip end resting on the round bar 2.

Further, when the plate material is further forwarded and the tip of the plate material A abuts against the stopper 4 as shown in FIG. 2c, the stopper 4 is separated from the conveying roller 3 by at least the length of the plate material A. The rear end portion of A comes off from the transport roller 3 and falls in the direction of arrow t in the figure. At this time, since the tip end of the plate material A is still on the round bar 2, the tip thereof jumps up above the stopper 4 about the contact point with the round bar 2, but the upper side of the stopper 4 is rearward in the transfer direction. Since the plate material A is curved or slanted, the distance from the trailing end of the plate material A to the stopper 4 is substantially uniform, and the position of the plate material A is not displaced by the jumping of the tip.

When the round bar further moves together with the chain, the leading end of the plate material A falls while rotating in the direction of arrow s around the rear end of the dropped plate material A as shown in FIG. 2d. After that, the round bar 2 comes into contact with the stop limit switch 32 and a signal thereof is output to the control panel, and the main chain 1 and the conveying roller 3 are stopped by the control from the control panel. Also, the plate material A that has dropped causes the arm 31a of the elevating limit switch 31 to rotate, and an elevating signal is output to the control panel. The cylinder 29 of the lifter 25 contracts only while the up / down signal and the stop signal are output, whereby the link arm 28 rotates in the direction of arrow r and the loading table 27 descends. When the loading platform 27 eventually descends to the position of the imaginary line in the figure, the loaded plate A is disengaged from the arm 31a of the lifting limit switch 31 and the arm 31a is opened as shown in FIG. 2a, so that the lifting signal is stopped. ,
This stops the lowering of the lifter 25. Further, in this embodiment, before the lifter 25 descends, the cylinder 23 of the pressing device 22 advances to push the dropped plate A toward the support plate 21 as shown in FIG.
To adhere. As a result, the stacking device of this embodiment can stack not only the front end of the plate material A but also the width direction.

In this embodiment, two round bars are used as the supporting tool, but the number and shape are not limited to this. Further, although the chain is used as the cord and moved by the sprocket, it may be moved by the pulley or the like by using, for example, a rope or a belt. Further, the number of lines is not limited to two, and three or more lines may be provided side by side. In this case, the support tool may be provided between the adjacent lines. Further, in this embodiment, the plate material is transferred in the horizontal direction in detail. However, if the plate material has an angle within a range that does not slip out against the frictional force with the round bar, the plate material is transferred in a slightly oblique direction. But it doesn't matter.

[0020]

As described above, according to the plate-shaped article loading device of the present invention, the support and the cords that move the support are placed with the tip of the plate-shaped article resting on the support. When the plate-like object is transferred by the conveying roller at the same speed and the leading end of the plate-like object hits the stopper, the plate-like object is disengaged from the conveying roller and the trailing end portion of the plate-like object in the transfer direction falls downwards. With the structure in which the plate-shaped object hits the stopper, the support tool is disengaged from the plate-shaped object and the leading end of the plate-shaped object in the transfer direction also falls downward, so the plate-shaped object does not rub anywhere and is scratched. It doesn't get stuck. Further, since the leading end portion of the plate-shaped object in the transfer direction drops downward in a state where the tip end of the plate-shaped object abuts on the stopper, the deviation of the tip ends is small and it is easy to align them. Furthermore, since there is no need to use an actuator or the like, there is no unevenness in operation and continuous loading work becomes possible.
