Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a panel holder of a transfer press capable of automatically adjusting a plurality of rods (hereinafter referred to as nests) for supporting a panel from below by internal setup. .

[Conventional technology]

Conventionally, the transfer press has a plurality of processing stations, and the panels to be molded are sequentially transferred to the processing stations by transfer bars.

In addition, on the panel unloading side of the transfer press, there is an auto palletizer that automatically loads the panels that have been molded by the transfer press onto the pallet and unloads them. It was transported to the auto palletizer with a transport device such as.

[Problems to be solved by the device]

However, since the auto palletizer is equipped with a panel loader that grips the panels transported by the transport device and loads the panels, if the panels are transported by a conveyor, the positioning accuracy at the panel stop position is poor, and as a result, Problems such as the panel loader not being able to grip the panel have occurred.

In addition, in the case of transporting by shuttle, the above problems do not occur, but since the nest provided on the shuttle has to be converted by internal setup every time the shape of the panel changes, a lot of man-hours are required for replacement work. There was a problem such as a need.

The present invention has been made for the purpose of improving the above problems, and an object thereof is to provide a panel holder for a transfer press in which one type of nest can accommodate various types of panels.

[Means and Actions for Solving the Problems]

In order to achieve the above object, the present invention provides a movable carriage that is movably provided on a guide rail that is installed so as to be orthogonal to the transport direction of a panel, and that is movable and adjustable in the contact and separation directions by a traverse motor. It is installed on multiple points on a horizontal rod which is erected on a moving carriage and whose height is freely adjustable by a lift motor, and a horizontal rod that is horizontally mounted between the upper ends of the columns that are separated in the panel transport direction. Equipped with multiple nest mounting members whose spacing can be adjusted in any direction, and nests that are detachably mounted on these nest mounting members, the nest spacing and height can be automatically set up according to the panel shape. It is intended to provide a transfer press panel pedestal that can be adjusted.

〔Example〕

 An embodiment of the present invention will be described in detail with reference to the drawings.

In the figure, reference numeral 1 denotes a main body of this apparatus, which is installed between a transfer press 2 and a panel pick-up position 3 of an automatic palletizer (not shown).

The main body 1 is separated in the carrying direction of the panel 4 (arrow A),
A pair of guide rails 5 are laid in a direction orthogonal to the guide rails 5, and two guide trucks 5 on each side, that is, a total of four moving carriages 6 are attached to the guide rails 5.

A screw shaft 7 is rotatably supported in each of the guide rails 5 so as to be parallel to the guide rails 5, and the movable carriage 6 is attached to screw portions 7a and 7b formed on the screw shafts 7 and having different screw directions.
The nut member 8 provided on the
By rotating, the movable carriages 6 can be moved and adjusted in the contact and separation directions.

One end side of each screw shaft 7 is interlocked with a bevel gear box 9 and an interlocking shaft 10, and is synchronously rotated by a transverse feed motor 12 connected to the interlocking shaft 10 via a chain 11.

On the other hand, a worm gear box 14 is installed on each of the movable carriages 6.

As shown in FIG. 4, the worm gear box 14 has a worm wheel 14b screwed onto a screw shaft 14a supported in the vertical direction, and when the worm wheel 14b rotates, the screw shaft 14a moves up and down. At the same time, a worm (not shown) interlocked with the interlocking shaft 15 is meshed with each worm wheel 14b, and each worm is moved by the lift motor 17 connected to the interlocking shaft 15 via the chain 16. By rotating, the screw shafts 14a of the movable carriage 6 separated in the panel transport direction A can be vertically adjusted in synchronization with each other.

The lower ends of the columns 18 are fixed to the upper ends of the screw shafts 14a. Each of the columns 18 is erected for each movable carriage 6, and a horizontal rod 19 is provided between the upper ends of the columns 18 spaced in the panel transport direction A.
Is crossed over.

Further, guide rails 20 having dovetail grooves 20a as shown in FIG. Is movably fitted.

Two nest mounting members 21 are provided for each guide rail 20 so that the spacing can be adjusted along the guide rails 20 and can be fixed to the adjusted position by the stopper handle 22. .

Further, each nest mounting member 21 is provided with a lift rod 24 which can be adjusted up and down by a vertical adjustment handle 23, and a nest 25 prepared as an attachment is attached to a mounting seat 24a provided at the upper end of these lift rods 24 as a fixture. It is detachably attached by 26.

Reference numeral 27 in the figure is a transfer bar provided in the transfer press 2 so that it can be three-dimensionally operated in a feed direction by a feed carrier 28, in a clamp direction by a clamp carrier 29, and in a lift direction by a lift mechanism (not shown). Has become.

The operation will be described below. The panel 4 which has been molded by the transfer press 2 is carried out by the transfer bar 27 from the final processing station to above the main body 1.
It is held by a nest 25 provided at a position close to the transfer press 2 side.

Then, by the next feeding operation, the nest 25 provided in the center of the horizontal rod 19 and the nest 25 provided at a position closer to the auto palletizer side are sequentially conveyed to the panel pick-up position 3 of the auto palletizer. It is gripped by a panel loader (not shown) of the auto palletizer and loaded on the pallet.

On the other hand, if the shape of the panel 4 molded by the transfer press 2 changes, it is necessary to change the interval and height of the nest 25 in accordance with this. First, when changing the interval, the screw shaft 7 is moved by the transverse feed motor 12. Rotate.

As a result, each moving carriage 6 moves in the approaching / separating direction, so that it stops at a desired interval.

The height can be adjusted by vertically adjusting the screw shaft 14a in the worm gear box 14 by the lift motor 17 and stopping when the desired height is reached.
The adjustment of can be done automatically by the internal setup.

6 and 7 show a state in which the nest 25 supports the panel 4 from below.

As is clear from these figures, by changing the spacing and height between nests, the same nest can be used even if the panel shape changes.
It is possible to deal with 25.

Further, since the interval adjustment of the nest 25 in the panel conveying direction A is infrequently used, the interval adjustment motor is manually operated in the above-mentioned embodiment, but it may be automatically provided by providing an interval adjustment motor. The height of the nest 25 can be adjusted for each nest 25 using the height adjustment handle, so panel 4
It is also possible to support various panel shapes, such as holding in a tilted state.

Further, although the above-mentioned embodiment shows the case where it is installed between the transfer press 2 and the automatic palletizer, it can also be used as a panel cradle installed in an idle station in the transfer press 2.

[Effect of the Invention] As described in detail above, the present invention can automatically adjust the nest interval and height according to the shape of the panel that has been molded by the transfer press and is carried out. Even if there is a change in the work conditions, it is not necessary for the worker to enter the apparatus each time to replace the nest by internal setup and adjust the intervals and heights.

Further, since the nest can be commonly used even if the shape of the panel is changed, it is economical because it is not necessary to prepare a plurality of types according to the panel shape as in the conventional case.
