[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a perforated panel loading method and apparatus for stacking perforated panels discharged from a press line such as a transfer press or a tandem press on a pallet in a skewered manner. .

[0002]

2. Description of the Related Art A panel loading apparatus for loading a perforated panel as a molded product discharged from a press line on a pallet has been conventionally used for, for example, unloading and loading side panels with windows from a transfer press in the automobile industry. Used. Depending on the loading state of the panels on the pallet, there are "flat loading" in which the panels are loaded almost horizontally, "standing" in which the panels are loaded almost vertically, and the like. There is a "standing and skewering" method in which a panel is suspended through a substantially horizontal support member in the hole. In a well-known panel loading device,
When a predetermined number of panels are loaded on a pallet, the pallet must be replaced with the next pallet. Since such replacement is performed manually by a worker, work efficiency is poor and the press line needs to be stopped. was there. Therefore, there has been a demand for a panel loading apparatus that can automatically replace panels without stopping the press line.

In order to satisfy such a demand, Japanese Utility Model Publication No.
An automatic loading device as disclosed in Japanese Patent No. 28605 has been proposed. In this automatic loading apparatus, a hanger-type pallet is sequentially moved in the front-rear direction and the up-down direction of a press line, and a panel carried out on a hanger is automatically loaded on the pallet. That is, as shown in FIG. 16, a substantially horizontal perforated panel 2 on the panel conveyor 1 of the press line is swung in a substantially vertical state to move the panel 2 to a panel delivery position A on the exit side of the panel conveyor 1. A loading conveyor 3 for transferring a hanger type pallet 4 formed by a U-shaped frame to the panel transfer position A, and a perforated panel 2 from the panel transfer device 3 at the panel transfer position A. And a hanger device 6 capable of receiving the perforated panel 2 and loading the perforated panel 2 on the hanger-type pallet 4.

The panel transfer device 3 has a traveling body 8 mounted on a guide rail 7 extending in a substantially horizontal direction laid above the panel transport conveyor 1 so as to be able to travel in the press line direction (arrow X direction). An arm 10 having a suction device (vacuum cup) 9 at its tip is rotatably attached to the traveling body 8. The hanger device 6 is arranged in parallel with the guide rail 7. A carrier 12 is provided on the extended guide rail 11 so as to be able to travel, and an L-shaped hanger 13 is provided on the carrier 12 so as to be able to move up and down.

In the automatic loading device, first, as shown in FIG. 16, a perforated panel 2 on a panel transport conveyor 1 is sequentially suspended by a panel transfer device 3 on a hanger 13 of a hanger device 6 at a panel transfer position A. 17, a predetermined number of perforated panels 2 are provided in the hanger 13 as shown in FIG.
Is suspended, the hanger pallet 4 is moved by the conveyor 5 to the panel delivery position A so as to penetrate the hole of the perforated panel 2, and as shown in FIG. Panel 2 with hanger pallet 4
As shown in FIG. 19, the hanger device 6 is retracted from the panel delivery position A and raised, and as shown in FIG. 20, the hanger device 6 is moved again to the panel delivery position A side, and the perforated panel 2 is removed. The loaded hanger type pallet 4 is carried out.

[0006]

However, in the case of the above-mentioned automatic loading device, since a large number of devices are moved in the front-rear direction and the vertical direction of the press line, the structure and control are complicated, and the device is long in the press line direction. In addition, there is a problem in that a further apparatus is required to carry in / out the pallet 4 in the lateral direction of the press line, and the degree of freedom in the factory layout is small. Further, as described above, the perforated panel 2 is temporarily suspended on the hanger device 6 and then transferred to the hanger type pallet 4, so that there is a high possibility that the perforated panel 2 will be damaged and the hanger device 6 will be damaged. When the perforated panel 2 is transferred from the hanger type pallet 4 to the hanger type pallet 4, the substantial moving stroke of the hanger device 6 including the moving stroke of the hanger type pallet 4 becomes longer, and the loading operation to the hanger type pallet 4 takes much time. , Which leads to a reduction in the operation rate of the press line, which is the previous process.

Conventionally, an automatic palletizing device (hereinafter referred to as Japanese Patent Publication No. 1-2578) is provided with a moving device on which a main hanger, a sub hanger, and a pallet are placed, and the sub hanger receives the panel while the panel is being loaded on the pallet by the main hanger. However, in the case of this device, the structure and control are complicated as in the case of the above-mentioned automatic loading device, and the device becomes longer in the length direction of the press line, and the pallet is moved in the lateral direction of the press line. There is a problem that additional equipment is required for loading and unloading, and the degree of freedom in the layout of the factory is small.

Therefore, the present invention can automatically replace panels without stopping the press line, has a simple structure and control, has a short length in the press line direction,
In addition, pallets can be loaded and unloaded in the horizontal direction of the press line, allowing greater flexibility in factory layout, reducing the occurrence of scratches on perforated panels, and loading pallets. It is an object of the present invention to provide a method and an apparatus for loading a perforated panel, which can reduce the time required and improve the operation rate of a press line.

[0009]

[0015]

Embodiments of the present invention will be described below with reference to the drawings.

FIGS. 1 to 5 show a first embodiment of a perforated panel loading apparatus according to the present invention.

In FIG. 1, a perforated panel 2 is discharged to the right in a substantially horizontal state by a panel conveyor 1 of a press line at the left end. The perforated panel loading apparatus of the present invention includes a panel transfer apparatus 3 for receiving a perforated panel 2 from a panel transport conveyor 1 of a press line and hanging it on a hanger 25b, and a hanger transfer apparatus 16 for vertically moving the hanger 25b.

The perforated panel 2 is, for example, a side panel with a window of an automobile or the like, and has an opening 2a as a hole as illustrated in FIG. By passing a plurality of substantially horizontal support rods through the opening 2a, the panel 2 can be suspended substantially vertically (that is, the panel 2 can be vertically stacked and skewered).

The hanger 25b has two cantilevered horizontal arms 22 for suspending the perforated panel 2 through the opening 2a of the perforated panel 2, as shown in FIG. A cantilevered horizontal arm 22 includes a base member 20 as a horizontal support portion that is cantilevered at the rear end. The space between the two cantilevered horizontal arms 22 of the base material 20 is cut out as shown in the drawing, so that it can be applied to a panel or the like having a projection.

As shown in FIG. 5A, the pallet main body 25a is provided with four pillars 1 standing at four corners of the bottom frame 17.
The upper end of the open-type wall 32 erected at the left and right ends of the bottom frame 17 is formed as the hanger support 31 as shown in FIG.
Alternatively, as shown in FIG. 5C, the upper end of a flat U-shaped wall 33 erected on the bottom frame 17 is used as a hanger support portion 31, and the hanger 25b is attached to the hanger support portion 31. The loading pallet 25 is provided as a hanger-type pallet by being placed on the pallet.

The length (W in the figure) of the hanger support 31 in the press line direction is determined by the hanger transfer device 16A.
(Specifically, the length of the hanger 25b in the press line direction should be sufficiently smaller so as not to interfere with the hook 36 described later.) Further, the bottom frame 17 of the pallet main body 25a exhibits a function of a support base that can be moved laterally by the pallet transport conveyor 30.

In FIG. 1, the panel transfer device 3 includes a traveling body 8 serving as a main body, a moving mechanism 34 for moving the traveling body 8 in the front-rear direction which is the press line direction (the direction of the arrow X), and a traveling body 8. An elevating mechanism (not shown) for elevating and lowering;
An arm 10 having a rear end (right end in the figure) pivotally attached thereto, a turning mechanism (not shown) for turning the arm 10 downward,
The suction device 9 is a vacuum cup that holds the perforated panel 2 on the arm 10 under negative pressure. As a result, the panel transfer device 3 receives the perforated panel 2 in a substantially horizontal state from the rear of the press line, turns the panel in a substantially vertical state, and moves rearward to a panel transfer position A (in the present embodiment) which is at a high position. The lower surface of the hanger substrate 20 is shown in the figure.
Holes can be suspended.

The hanger transfer device 16A comprises a plurality of hooks 36 having a projection 35 for supporting the substrate 20 of the hanger 25b substantially horizontally, and a plurality of vertical rods 37 to which the hooks 36 are fixed at lower ends. And an elevating mechanism 38 for elevating and lowering the vertical rod 37. The elevating mechanism 38 includes, for example, a connecting portion 39 that connects the plurality of vertical rods 37 and a drive cylinder 40 that moves the connecting portion 39 up and down, as shown in the drawing. With this configuration, the hook 36 is lowered to lower the hanger 25b to the pallet main body standby position C (in this embodiment, the lower surface of the hanger base 20 is shown), and the base 20 of the hanger 25b is moved to the pallet main body 25a.
The hook 36 can be detached from the hanger 25b by placing the hook 36 on the hanger support portion 31 and further lowering the hook 36 continuously before the lateral movement of the pallet 25. In order to detach the hook 36 from the hanger 25b, a structure other than the above-described configuration, for example, the hook 36 may be pivotally attached to the vertical rod 37 and the hanger 25b may be released by pivoting the hook 36. . With this configuration, it can be easily applied to hangers of different dimensions.

As shown in FIG. 2, the hanger 25b is placed on a pallet body 25a, and is loaded and unloaded as a loading pallet 25 in a lateral direction of the press line (from left to right in the figure). The pallet conveyor 30 can move a plurality of loading pallets 25 at the same time. The pallet transport conveyor 30 is a normal roller conveyor, a chain conveyor, or a belt conveyor, and moves laterally at right angles to the press line at least below the hanger transfer device 16A. With this configuration, the empty hanger 2
It is possible to simultaneously carry in the pallet 25 in which the pallet 5b is placed on the pallet body 25a and carry out the pallet 25 in which the plurality of panels 2 are loaded.

The perforated panel loading device described above operates as follows.

First, the perforated panel 2 is received in a substantially horizontal state from the panel transport conveyor 1 of the press line by the suction device 9 of the panel transfer device 3, raised and retracted, and then the arm 10 is turned by the turning mechanism to turn the panel 2. Is pivoted substantially vertically, and further moved rearward by the moving mechanism 34 to suspend the opening 2a of the panel 2 on the cantilevered horizontal arm 22 of the hanger 25b at the panel delivery position A. This process is repeated until a predetermined number of panels 2 are received by the hanger 25b. When a predetermined number of panels 2 are received in the hanger 25b, the hanger 25b is lowered to the pallet main body standby position C by lowering the hooks 36 by the lifting mechanism 38 of the hanger transfer device 16A, and the base material 20 of the hanger 25b is palletized. The hook 36 is placed on the hanger support portion 31 of the main body 25a, and then the hook 36 is lowered to release the hook 36 from the hanger 25b.

Next, the pallet conveyor 30
The pallet 25 having the hanger 25b placed on the pallet body 25a is laterally moved, and at the same time, the empty pallet 25 is laterally moved, so that the empty pallet 25 is located at the lower part of the hanger transfer device 16A, that is, at the position of the full pallet 25 before the movement. Position. Then, the hook 36 is raised by the lifting mechanism 38 of the hanger transfer device 16A, so that the empty pallet 2
Then, the hanger 25b of No. 5 is raised to the panel transfer position A, and returns to the initial operating state.

As described above, in the present invention, the pallet 25 having received the predetermined number of panels 2 can be replaced with an empty pallet 25 only by the steps of raising and lowering the hanger 25b and moving the pallet 25 laterally. Therefore, by performing such a process in a short time, the pallet 25 can be automatically replaced without stopping the press line.

The above-described process is performed by the hanger transfer device 16A.
Is achieved only by up and down movement and lateral movement by the pallet conveyor 30.
Structure and control are also simplified. Further, since the pallet 25 is less moved in the unloading direction and the pallet 25 is unloaded directly from the press line in the horizontal direction, the length of the apparatus in the press line direction is short, and the degree of freedom in the factory layout is large.

Further, the hanger transfer device 16A is provided with a hanger 2
5b is provided with a hook 36 for supporting the base material 20 of the hanger 25b.
Can be put on the hanger support portion 31 of the pallet body 25a, and the hook 36 can be released from the hanger 25b at a low position by further lowering the hook 36 continuously before the pallet 25 moves laterally. Hanger 2 with a simple structure without increasing the time required for
5b can be moved up and down.

Next, FIG. 6 shows a second embodiment of the present invention. In a configuration similar to that of the first embodiment, two rows of pallet transport conveyors 30 are arranged side by side and a hanger transfer device 16A is used. The two pallet transfer conveyors 30 are arranged in parallel and the moving mechanism 34 of the panel transfer device 3 is formed so as to extend rearward in the press line direction so as to correspond to the pallet transport conveyor 30 arranged in parallel.

In the case of the second embodiment shown in FIG. 6, operations such as loading of the panel 2 and loading and unloading of the pallet 25 can be performed alternately on the two pallet conveyors 30. Work can be performed more efficiently.

FIGS. 7 to 10 show a third embodiment of the present invention, which can be detachably mounted on the pallet body 25a.
And a hanger transport conveyor 14 capable of supplying a hanger 25b constituting the loading pallet 25 together with the pallet body 25a to a hanger standby position B below the panel transfer position A so as to extend in a direction perpendicular to the panel transport conveyor 1; The pallet main body 25a can be supplied to the pallet main body standby position C on the side opposite to the panel transport conveyor 1 at the hanger standby position B,
And a pallet main body conveyor 15 capable of carrying the pallet main body 25a out of the pallet main body standby position C is provided in parallel with the hanger transport conveyor 14, and the hanger 25b at the hanger standby position B can be moved to the panel transfer position A. Further, there is provided a hanger transfer device 16B capable of transferring the hanger 25b with the perforated panel 2 suspended at the panel transfer position A onto the pallet main body 25a at the pallet main body standby position C.

The pallet body 25a is formed by erecting columns 19 having projections 18 at the upper ends at four corners of the bottom frame 17, and the hanger 25b has a U-shape in plan view. And on a substrate 20 that can be placed on the column 19,
A hole 21 into which the protrusion 18 can be fitted is formed, and a cantilevered horizontal arm 22 capable of suspending the L-shaped perforated panel 2 is integrally provided on the lower surface of the base material 20 to form the same. is there.

The hanger transfer device 16B is mounted on a carrier 12 movably mounted on a guide rail 11 extending in parallel with the guide rail 7, and a base material 20 of the hanger 25b.
L-shaped transfer arm 24 having support pieces 23 for supporting both sides of the transfer arm 24 is provided so as to be able to move up and down.

The same parts as those in FIG. 16 are denoted by the same reference numerals.

When loading the perforated panel 2,
The hanger 25b is carried into the hanger standby position B by the hanger transport conveyor 14, and the hanger 25b carried into the hanger standby position B is placed on the support piece 23 as shown in FIG.
0 is lifted to the panel delivery position A by the transfer arm 24 of the hanger transfer device 16B in a state where both sides of the panel transfer device are mounted, and in this state, the perforated panel 2 on the panel transport conveyor 1 is moved to the panel transfer device 16B. 3, the hangers 25b at the panel delivery position A are sequentially skewered and hung.

In the meantime, when the pallet main body 25a is carried into the pallet main body standby position C by the pallet main body conveyor 15 and the predetermined perforated panel 2 is hung on the hanger 25b, the transfer arm of the hanger transfer device 16B is moved. 7, the hanger 25b is horizontally moved as indicated by the solid arrow in FIG. 7, then lowered to the pallet main body standby position C side, and placed integrally on the column 19 of the pallet main body 25a.
The loading pallet 25 in which the perforated panels 2 are loaded is obtained. Instead of lowering the hanger 25b to the pallet main body standby position C after horizontally moving the hanger 25b as indicated by the solid arrow in FIG. 7 as described above, the hanger 25b May be moved obliquely as shown by an arrow of a virtual line in FIG.

At this time, the transfer arm 24 is positioned at a position where a slight gap G is formed between the upper surface of the support piece 23 and the lower surface of the base material 20 of the hanger 25b, as shown in FIG.
The hanger 25b is lowered to a position where the hanger 25b is completely supported by the pallet main body 25a. From this state, the hanger 25b horizontally moves to the hanger standby position B, and the next hanger 25b carried into the hanger standby position B is moved to the hanger standby position B. The loading pallet 25 loaded with the perforated panel 2 is lifted by the loading arm 24 in the same manner as described above, and is unloaded by the pallet body transport conveyor 15 and the next pallet body 25a is moved to the pallet body standby position. C
The same operation as described above is repeatedly performed. It is needless to say that the direction in which the loading pallet 25 loaded with the perforated panels 2 is carried out may be the direction indicated by the imaginary arrow in FIG.

In this manner, the perforated panel 2 is once suspended on the hanger device 6 as in the conventional example shown in FIGS. 16 to 20, and is not loaded on the hanger type pallet 4, but can be directly loaded on the hanger 25b. It is possible to reduce the occurrence of scratches on the perforated panel 2 and to shorten the substantial moving stroke of the hanger transfer device 16B, thereby reducing the time required for loading work on the loading pallet 25, This will also help improve the operation rate of the press line.

FIG. 11 shows a fourth embodiment of the present invention. In the same configuration as the third embodiment shown in FIGS. 7 to 10, a hanger transport conveyor 14 for transporting a hanger 25b and a pallet The pallet main body conveyor 15 that conveys the main body 25a is disposed opposite to the press line direction.

In the case of the fourth embodiment shown in FIG.

3, the lifting operation of the hollow elevating member 41 with respect to the support rod 44 is restricted, so that the holding force of the left and right hooks 36 on the hanger 25b is kept constant so as not to be applied more than necessary.

Further, when the lifting operation of the hollow lifting member 41 is continued, the lifting force of the hollow lifting member 41 is reduced by the nut 43.
14 through the support rod 44, the horizontal beam 45 is displaced upward while being guided by the guide rod 47, as shown in FIG. For this reason, the hanger 2 held by the hook 36
5b is lifted off from the upper end of the pallet body 25a.

When the hanger 25b is positioned at the panel delivery position A while the hanger 25b is gripped by the hook 36, the panel 2 is sequentially fed into the hanger 25b by the panel transfer device 3 in a skewered state. The specified number of panels 2 is hanger 2
5b, the data is sent to FIG.
The panel 2 is loaded on the pallet 25 in a process opposite to the process shown in (c). That is, as shown in (c) of FIG. 14, in a state where the hanger 25b in which the panel 2 is skewered is positioned above the pallet body 25a, the lowering operation of the hollow lifting member 41 as shown in (b) of FIG. Lowers the horizontal beam 45 to move the hanger 25b into the pallet body 2
Then, as shown in FIG. 14A, the left and right hooks 36 are opened by further lowering operation of the hollow elevating member 41 to release the grip of the hanger 25b. Thereby, the panel 2 can be loaded on the pallet 25. The loaded panels 2 are carried out by the movement of the pallet transport conveyor 30 for each pallet 25.

After the operation on the pallet 0, the hanger transfer device 16C is moved onto the pallet transport conveyor 30 on the side opposite to the panel transport conveyor 1, and the panel 2 is loaded in the same manner.

In the above, the loading of the panel 2 onto the pallet 25 can be performed by the vertical movement of the hook 36 by the horizontal beam 45 and the opening and closing movement of the hook 36 by the link 49, so that the operation is simple. Since the bogie frame 39 is merely moved to the transfer position A of the panel 2 for centering, work can be performed efficiently.

In the above description, the case where two pallet transport conveyors 30 are arranged side by side on the exit side of the panel transport conveyor 1 is shown, but instead of arranging two pallet transport conveyors 30 side by side, FIG. 7 or as shown in FIG.
Hanger conveyor 14 and pallet body conveyor 1
5 are arranged side by side, and the hanger 2 is provided between the two conveyors 14 and 15.
5b and the pallet body 25a may be handled.

The present invention is not limited to the above embodiment. For example, in the third embodiment shown in FIG. 7, both ends of the hanger base material are gripped by the support pieces of the hanger transfer device. Needless to say, various changes can be made without departing from the spirit of the present invention, for example, an openable clamp mechanism may be added.
