JPH03128817A - Device for delivering plate material to carrying base - Google Patents

Abstract

PURPOSE:To smoothly deliver plate materials leaningly against carrying base in the above device for a press-molded plate material by providing a carrying base to support a plate material leaningly against it opposite to a conveyor base, and stopping the plate material at the end of the conveyor base, and inverting the conveyor base to transfer the plate material onto the carrying base. CONSTITUTION:A protruded stopper 13 stopes a plate material P in a process of laterally carrying on a conveyor base 1, which is then rotated around a shaft 8. In this case, a plate receiving face 16 of the stopper 13 comes into contact with a receiving part 21 of a carrying base 2 through a roller 18, and therefore rotates downward under reaction force caused by the receiving part 21 to sink below an upper face of the carrying base 2. The lower end of the plate material P is simultaneously transferred onto the receiving part 21 of the carrying base 2, and the plate material P is laid leaningly against a leaning part 20. The carrying base 2 moves back immediately after the laying of the plate material P. Thus the plate material P can be smoothly laid leaningly against the part 20.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention aims to sequentially transport plate materials such as stainless steel, which have been formed by, for example, a shearing or pressing machine and are transported laterally on a conveyor, onto a loading table. , relates to a board delivery device (hereinafter also simply referred to as device) for stacking board materials leaning against each other.

(Prior Art) As a conventionally known device for transferring plates to a loading table, there is a plate stacking device disclosed in Japanese Patent Publication No. 40-2180. In this system, the plates that are sequentially conveyed and supplied laterally in a horizontal state are stacked in a horizontal state by dropping them directly from the end of the roller conveyor or through a chute. This is what I did.

(Problems to be Solved by the Invention) In the above-described conventional apparatus, the plate material is transferred to and from the loading table by allowing the plate material as a product to fall naturally due to gravity. For this reason, when the plates are loaded one after another by this device, the plates are subject to a large impact, and therefore the surface of the plates is easily damaged, which reduces the commercial value of the plates.

Moreover, for example, when taking out one sheet at a time from a large number of sheets after loading them onto a loading platform, the following problem occurs. That is, since the plate material to be taken out is generally taken out by grasping both ends, a large bending inevitably occurs in the center. As a result, during handling such as transportation, the surface of the central portion is often scratched. This is especially true for thin and long items, which are handled in a form with low bending rigidity, and there is also the problem that an unnecessarily large number of workers may be required to transport them. Improvements have been requested for some time.

In order to meet these demands, the present invention is based on the fact that the cause of the above-mentioned problem is that the plate materials being conveyed laterally are dropped from a conveyor table as they are, and then transferred to a loading table and stacked. Focusing on a certain point, we devised an apparatus for the purpose of providing a device that can smoothly transfer plate materials that are transported in a horizontal state while leaning against a loading platform.

(Means for Solving the Problems) In order to achieve the above object, a device for delivering plate materials to a loading platform according to the present invention is provided with a conveyor table, and a device that is installed separably with respect to the conveyor table, and supports the plate materials against the conveyor table. The conveyor table has a stopper for stopping the plate material being conveyed laterally on the conveyor table, and a stopper for stopping the plate materials conveyed laterally on the conveyor table, and a stopper for stopping the plate materials conveyed in the horizontal direction on the conveyor table, and a stopper for stopping the plate materials conveyed in the horizontal direction on the conveyor table, and The conveyor table is provided with a means for reversing the conveyor table for transferring the plate material while leaning against the table.

(Function) With the above configuration, when the conveyed plate material is stopped by the stopper on the conveyor table and the conveyor table is reversed by the required amount, the plate material is delivered while leaning against the loading table.

(Example) Next, an example of the apparatus according to the present invention will be described based on FIGS. 1 to 3.

FIG. 1 is a schematic side view showing the entire structure of this embodiment, showing a conveyor table 1 that maintains a slight downward slope and receives and stops a plate material P conveyed from a conveyor (not shown); The main body is a loading platform 2 which is installed separably from the conveyor platform 1 as will be described later, and these components are mounted on a trolley 3, which will be described in detail below.

In the conveyor stand 1, a frame 4 constituting the bottom thereof is formed into a substantially U-shape on the side surface, and a roller conveyor 5 is mounted on both legs of the frame 4 in a mounting manner.

However, the roller conveyor 5 is located at the front end of the frame 4 (first
It is rotatably attached to the leg (on the left side as viewed in the figure) via a shaft 6.

A substantially doglegged link 7, which constitutes a reversing drive means for the conveyor table 1, is integrally connected to the bottom of the frame 4 via its upper end. A shaft 8 is attached to the bent portion of the link 7, and the conveyor table 1 is rotatably supported by a pair of bearings 9 at both ends thereof.

In addition, in this example, this bearing 9 is provided at the right end of the truck 3 on the top of the stand 10 that is erected.
It is fixed to the 5 degree slope.

On the other hand, at the lower end of the link 7, a so-called clevis-type pneumatic cylinder, which constitutes a reversing drive means for the conveyor table 1, is supported so as to be able to swing up and down with respect to the carriage 3, with the rear end being the center of rotation. The tip of the first cylinder rod is fixed to the shaft.

When the pneumatic cylinder 1 is activated, the cylinder rod is pushed out, as shown by the two-dot chain line in the figure, and at the same time, the conveyor table 1 is turned over and directed to a vertical position.

Furthermore, in this example, a so-called front trunnion type pneumatic cylinder 2 is attached to the right side of the frame 4 of the conveyor stand 1, and as shown in FIG. 2, the lower surface of the roller conveyor 5 is pushed out. An auxiliary reversing drive means for the conveyor table 1 is configured so that only the roller conveyor 5 can be reversed about the shaft body 6.

Further, the conveyor table 1 is provided with a stopper 1 for stopping the plate material P conveyed laterally on the conveyor table 1.
3 is attached to a pair of substantially triangular brackets 14 fixed to the ends of the frame 4. However, in this example, it is attached to the shaft 15 passing through the stopper 13 and the bracket 14 as described below so that it can move using the shaft 15 as a fulcrum. That is, the stopper 13 has its plate receiving surface 16
is approximately perpendicular to the top surface of the conveyor table 1, and the shaft 15
The end opposite to the plate holder 16 is pulled diagonally downward by the coil spring 17 using the so-called "lever principle," and the plate is placed under no load or under a slight load (about the weight of one ordinary plate). For example, the stopper 13 is prevented from moving from the vertical position. Further, a support shaft is provided protruding outward from the stopper 13 between the shaft 15 and the coil spring 17, and a roller 18 is attached to the tip of the support shaft.

In this example, although not shown in detail, one small pneumatic cylinder is installed at the end of the frame 4 with the tip end of its cylinder rod positioned slightly below the top surface of the rollers of the roller conveyor 5 before operation. , is fixed to the central part on a plane, so that the lower end of the plate P can be pushed out when transferring the plate P to the loading table 2 (see FIG. 2).

On the other hand, in this example, the loading platform 2 is formed of a square pipe into an oval shape, and has a frame-like structure with a leaning part 20 for the plate material P erected at the upper part and a receiving part 21 for the plate material P at the lower part. It is formed. However, the square pipe forming the receiving portion 21 of the plate material P is arranged in a positional relationship that allows it to press the roller 18 of the stopper 13 upward as the conveyor table 1 is reversed. As a result, when the conveyor table 1 is inverted to a substantially vertical position, the plate receiving surface 16 is rotated downward and is configured to sink from the upper surface of the receiving portion 21 of the loading table 2 (see Fig. 2). and Figure 3).

Further, the loading platform 2 is placed with respect to a cradle 22 having an upward slope to the right and whose bottom portion is placed on the trolley 3 as described below. That is, the loading table 2 has a protruding portion 23 formed on its lower surface, is engaged with a protruding portion 24 on the upper surface of the receiving table 22, and is placed so as to be separable and maintain its position. On the other hand, the pedestal 22 is attached to a guide rail so as to be able to slide along its slope (not shown), and the motor 26 is attached to a screw hole provided in a protrusion 25 protruding from the bottom of the pedestal. Rotating shaft and rotating bearing 27
A screw rod 28, which is pivotally supported by the screw rod 28, is screwed together and maintained in its position. For example, if the motor 26 is rotated clockwise, the pedestal 22 and the loading platform 2 will move to the left, and if the motor 26 is rotated in the opposite direction, they will be moved to the right. It can be adjusted as appropriate depending on the load capacity. Two reinforcing members for the leaning portion 2o are attached by welding in this example.

Note that the apparatus of this example has a configuration that is approximately symmetrical on a plane with respect to the conveying direction of the plate material P.

Next, the operation and effects of this example will be explained.

The plate material P that has been conveyed in the lateral direction is stopped by a stopper 13 on the conveyor table 1: When the pneumatic cylinder 11, which is the reversal driving means of the conveyor table 1, is operated, the conveyor table 1 is rotated around the shaft 8. Rotate. The plate receiving surface 16 of the stopper 13 is rotated downward by the reaction force received from the receiving portion 21 of the loading platform 2 via the roller 18, and is lowered from the upper surface of the loading platform. At the same time, plate material P
The lower end portion (lower edge) of is brought into contact with the receiving portion 21 of the loading platform 2, and the loading platform 2 is transferred in a state where it is leaning against the loading platform 2.

In this example, the pneumatic cylinder 19 is actuated to push the lower end of the plate material P, and the pneumatic cylinder 12, which is an auxiliary reversing drive means, is actuated to push out only the roller conveyor 5 as shown by the arrow. The plate material P is delivered and placed against the leaning part 20. Then, in accordance with the reverse procedure, each pneumatic cylinder is operated to return the conveyor table 1, etc. to its original position, and receive the next plate material to be conveyed.

In this way, by repeating this operation while appropriately retreating and adjusting the position of the loading platform 2, the plates can be stacked on the loading platform 02 in an orderly manner.

In this way, in this example, the pneumatic cylinders 11 and 12 allow the plate materials to be delivered and placed against each other very smoothly. Moreover, since the loading form does not rely on gravity falling, even when the plates are loaded one after another, the impact received on the surface of the plates is small, so scratches are actively prevented.

Moreover, after loading a predetermined amount of plate materials onto one loading platform 2, the loading platform is separated from the apparatus using a crane or the like as appropriate, and transported to a workshop for the next process, a warehouse, or the like. After this, when two workers take out the planks one by one by grasping both ends, the planks are stacked vertically, compared to the conventional case where they are stacked horizontally. Since the section modulus in this state is extremely large, there is almost no downward deflection even if the plate is lifted, and therefore, damage to the surface of the central part of the plate during transportation is almost eliminated. Furthermore, compared to devices that are loaded horizontally, the installation space is smaller and it is more economical.

1 In this example, a pneumatic cylinder 12 is provided as an auxiliary reversing drive means for the conveyor table 1, and one pneumatic cylinder is further added to the structure.

Further, although a technique has been shown in which the link is rotated by a predetermined angle using a pneumatic cylinder as a reversal driving means for the plate material P, it is of course not limited to this. Of course,
It is also possible to use a hydraulic cylinder or, for example, a pneumatic cylinder similar to that in this example, which can be reciprocated to directly reverse the conveyor table. Alternatively, the shaft 8 of the bearing 9 may be rotated by a predetermined angle by a deceleration electric motor. Note that when the pneumatic cylinder 12 as the auxiliary reversing drive means is not used, the conveyor stand 1 may have the roller conveyor 5 and the frame 4 integrated.

In this example, the stopper 13 is movable, but it may be fixed. In addition, in order to prevent damage to the edges of the plate material as much as possible, it is preferable to attach a cushioning material such as a synthetic resin plate to the temporary receiving surface of the stopper and the surface of the loading platform.

(Effects) As is clear from the above description, the apparatus according to the present invention has the following effects.

That is, in the apparatus of the present invention, the plate material transported laterally can be delivered while leaning against the loading table. Therefore, when the plate materials are loaded one after another by this device, the impact received by the plate materials is small, and therefore the damage to the surface thereof is reduced.

In addition, in the process after loading, even if two workers take out the planks one by one by grasping both ends, the section modulus in that state is large, and as a result, large deflections are prevented. This is extremely effective in preventing scratches on the surface of the central portion, which has been a problem during transportation.
