Abstract

PURPOSE:To aim at automation in turnover operation on a panel material, by installing two-in-a-set guide vanes paralleled with each other projectingly in a turning shaft, and transferring the panel material thrust in a clearance of these guide vanes reversely to the side of a take-out conveyor by a take-in conveyor in a way of rotating these guide vanes as far as 180 deg.. CONSTITUTION:At each one surface of a sectional square base member 12e being fitted in a turning shaft 12, two sheets of plate bodies 11a and 11b are formed into a set with a clearance being somewhat larger than thickness of a panel material, and guide vanes 11 are formed up. The panel material taken in by a take-in conveyer enters a clearance between these guide vanes 11, then if the turnimg shaft 11 is rotated, inside and outside of the panel material are turned over when it rotates as far as 180 deg., and it is mounted on a take-out conveyor 30 which is being mounted on a slide base 34 to be driven by an air cylinder 33 on the whole, thus it is designed so as to shift the whole body in a take-out direction. With this constitution, the turnover operation of the panel material can be made into automation.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an inverting device for panel materials used in a manufacturing line for panel materials, such as architectural roof panels.

PRIOR ART Panel materials such as architectural roof panels are manufactured on a continuous production line, but when manufacturing such a flat plate-like product, first, the processing on the negative side is completed, the whole is turned over, and then the other side is turned over. It is common to process one side of the .

For example, when making a roof panel by attaching temporary shrines to both sides of the frame, first attach a board to one side of the frame, then flip this semi-finished product and attach a board to the other side to complete the finished product. The reason for this is that holding a flat panel material vertically and transporting it is much more troublesome than holding it horizontally and transporting it. by.

In panels manufacturing factories, this work of reversing panel materials has traditionally been done exclusively by hand, which is not only inefficient, but also difficult when the panel materials are large and heavy. However, the problem of forcing workers to perform harsh physical labor was unavoidable.

Purpose of the Invention In view of the actual state of the prior art, an object of the present invention is to provide a novel panel material reversing device that is incorporated into a continuous panel material manufacturing line and automatically performs the panel material reversing operation. Our goal is to provide the following.

Structure of the Invention The structure of the present invention to achieve the above object is to provide a horizontal rotation shaft, protrude from the rotation shaft a plurality of guide vanes each consisting of a set of two mutually parallel plates, and A carry-in conveyor and a carry-out conveyor are arranged with the axis in between, and the panel material inserted into the gap between the two sets of guide blades in the horizontal position by the carry-in conveyor is moved upwardly by the guide blades.
By rotating the panel material by 80 degrees, transferring it inverted to the opposite side of the rotation axis, and then pulling it out through the gap between the guide vanes by the carry-out conveyor and carrying it out, the entire rotational movement of the panel material forms the two sheets that constitute the guide vanes. Therefore, the gist of the invention is to make it possible to invert the panel material without impact or vibration.

Example Embodiments will be described below with reference to the drawings.

The panel material reversing device includes an inlet conveyor 20 and an outlet conveyor 30, sandwiching a rotary shaft 12 having guide vanes 11, 11, . . . projecting therebetween (FIG. 1).

The rotating shaft 12 is a horizontal shaft rotatably supported by pillow blocks 12a, 12a..., and one end thereof is connected to the motor 12d via a set of bevel gears 12b and a speed reducer 12C. By controlling the motor 12d using an angle detector (not shown), the two sets of guide vanes 11 facing each other can rotate in units of 90' while maintaining a horizontal position. The direction of rotation is the direction in which the upstream (upper side in FIG. 1) guide vane 11 rotates upward, that is, the counterclockwise direction when viewed from the direction of arrow Y in FIG.

The guide vane 11 consists of a set of two plate bodies 11a11jb that are protruded with a gap d from each side of a base member 12e with a substantially square cross section that is fitted onto the rotating shaft 12, and has a diameter of 90'.
Four sets are provided at intervals to form one block (FIGS. 2 and 3). The guide vanes 11, 11... are provided with three blocks without twisting in the axial direction of the rotating shaft 12 (Fig. 1), and the mutual spacing between them is necessary to handle the panel material P to be reversed. This is to ensure sufficient dimensions.

The length of the two plates 11a and 11b, which constitute the guide vane 11 and whose surfaces are parallel to each other, is such that the plate 11b located on the rotation direction side of the rotation shaft 12 (upper side in the upstream horizontal position) is longer than the other plate 11b. (FIG. 2), and the mutual gap d is selected to be slightly larger than the thickness of the panel material P.

The carry-in conveyor 20 is a chain conveyor (Fig. 1), and includes chains 22a, 22b stretched from side to side along the carry-in path indicated by arrow A in the figure, and guide blades 11, 11, .
- Chains 22G and 22e installed horizontally at the intermediate interval, and chain 22d stretched on the left side of the end of the carry-in path.
The panel material P can be carried in horizontally.

That is, the motor 21 causes the chain 22 to rotate by rotating the shaft 21b via the drive chain 21a.
When the chains 22a, 22e are driven and the chains 22a, 22G are further driven via the connecting chain 21G and the shaft 21d, the chain 22b is also driven by the shaft 21e. ...is-
It seems like they are being driven in unison. In addition, each chain 22
Guide members 23a, 2 are provided on both outer sides of a, 22b...
3b is attached.

The height of the upper surface of each chain 22a, 22b... is determined by the gap d between the two plates 11a, 11b of the guide vane 11 in a horizontal position on the upstream side.
(The second
figure). Further, a stopper 24 is provided at the end of the carry-in path, and by abutting the front end of the panel material P, the position can be determined.

The carry-out conveyor 30 is also a chain conveyor, and can carry out the panel material P in the longitudinal direction of the guide blades 11 on the downstream side (in the direction of arrow B in FIG. 1). That is, the rotational force of the motor 31 is transmitted to the drive shaft 3 via the drive chain 31a.
1b, the chains 32a, 32a stretched between the intermediate interval and both ends of the guide vanes 11, 11...
. . . are driven simultaneously. However, the entire delivery conveyor 30 is mounted on a slide base 34 driven by an air cylinder 33 (Fig. 2),
The whole can be moved in the unloading direction indicated by the arrow B. Chains 32a, 32a...
- The upper surface position is determined so as to support the panel material P in a horizontal position on the downstream side from below and not to press it against the upper plate body 11b of the guide vane 11.

The operation of the panel material reversing device having such a configuration is as follows.

The rotating shaft 12 is rotated by the motor 12d, and the guide vane 1
1.11... takes a vertical position and a horizontal position (FIG. 2), the conveyor 30 is in a stopped state, and the air cylinder 33 is retracted and placed in a standby position.

Operating the conveyor 20, the left and right guide members 23a,
When the panel material P is carried in the direction of the arrow A in FIG.
is inserted into the gap d of the guide vanes 11.11..., so the panel material P is
1... Passes through the gap d and is positioned by hitting the stopper 24 provided at the end of the carry-in path with its tip (
Figure 1). That is, when the carry-in conveyor 20 is stopped at the time when the positioning is completed, the panel material P is inserted into the gap d between the three blocks of guide vanes 11, 11, . . . along the axial direction of the rotating shaft 12.

Next, when the motor 12d is energized and the rotating shaft 12 is rotated 90 degrees in the direction of the arrow in FIG.
・ takes a horizontal position, and the panel material P that was brought in earlier rotates upward and stands up as the guide blade 11.11 ・
It is made to stand vertically by... The movement of the panel material P at this time is necessarily pushed up by the lower plate bodies 11b, 11b, . . ., so it is smooth and there is no risk of generating shocks or vibrations.

The carry-in conveyor 20 is restarted, another panel material P is carried in, and it is inserted into the gap d between the guide vanes 11, 11, which have come to occupy a horizontal position on the upstream side in the previous process, When the guide vanes 11, 11... are roughly rotated by 90', the panel material P carried in first is transferred horizontally in an inverted state to the downstream side of the rotating shaft 12, while the panel material P carried in second is transferred horizontally to the downstream side of the rotating shaft 12. The panel member P stands vertically, and other guide vanes 11, 11, . . . are positioned horizontally on the upstream side. At this time, the movement of the panel material P brought in first is the other plate 1'la of the guide vanes 11, 11...
, 11a, . . . , so that it can be performed without impact or commotion, as described above.

The panel material P that has been reversely transferred to the horizontal position on the downstream side of the rotating shaft 12 is finally in a state where its lower surface is supported by the unloading conveyor 30. Therefore, the air cylinder 33 is extended and the slide base 34 is moved. By pushing out the panel material P in the unloading direction, the gap d between the guide vanes 11, 11...
can be extracted from. Therefore, the unloading conveyor 30
By operating the panel material P, the panel material P can be sent to the next step (not shown) in an inverted state. When the unloading of panels + and 4P is completed, the operation of the unloading conveyor 30 is stopped, the air cylinder 33 is shortened, and the unloading conveyor 30 is
Return to the original standby position.

By repeating the above operations, the panel vIP being carried in can be continuously reversed and carried out.

In the above explanation, the guide vanes 11, 11... can be provided in any plurality of sets protruding at equal angles around the rotating shaft 12, but in that case, the guide vanes 11, 11, etc. may be provided in opposite directions with the rotating shaft 12 in between. It is preferable to use an even number of sets so that the two sets protruding from the sides are in a straight line with each other. This is because it is sufficient to set the rotation angle of the rotating shaft 12 on either the upstream side or the downstream side. Furthermore, the number of blocks of guide vanes 11, 11, etc. provided in the axial direction of the rotating shaft 12 does not need to be limited to the aforementioned three blocks, and can be any number that matches the length of the panel material P. shall be taken as a thing.

Note that the two plates 11a, 11 that constitute the guide vane 11
It goes without saying that b is preferably as short as possible as long as it can hold the panel material P during rotational movement;
Among these, the one on the rotational direction side of the rotating shaft 12 can be made shorter than the other, as described above. That is,
Even if the panel material P inserted into the gap d of the guide vanes 11 on the carry-in conveyor 20 is positioned somewhat apart from the base member 12 e fitted on the rotating shaft 12 for some reason, it will not rotate upward by 90 degrees. When pressed, the lower end of the panel material P is completely brought into close contact with the base member 12e due to its own weight, so there is a risk that the panel material P will fall off from the guide blades 11, 11, etc. during the second half of the rotational movement. This is because the quality is significantly reduced.

Additionally, in this example, the direction in which the panel material P was carried in was parallel to the rotating shaft 12, and the direction in which it was carried out was set perpendicular to it, but as is clear from the above explanation, the combination of these directions It can be determined arbitrarily. That is, even if the driving directions of the carry-in conveyor 20 and the carry-out conveyor 30 are changed, there is no possibility that the operation of the rotating shaft 12 and the guide vanes 11, 11, . . . will be affected in any way.

As described in the detailed description of the invention; according to the invention, two parallel
A set of guide vanes is provided protruding from the rotating shaft, and on the upstream side, the panel material inserted into the gap between the guide vanes by an incoming conveyor is reversely transferred to the downstream side by rotating the guide vanes 180 degrees upward. In addition, we have made it possible to perform continuous reversal of panel materials by transporting them out using a conveyor installed downstream, making it easy to integrate into a continuous panel production line and automate the reversal operation. In addition, the entire rotational movement of the panel material is regulated by the guide vanes, so even if the panel material is large and heavy, the reversal operation is extremely smooth and can be performed without impact or impact. It has an extremely excellent effect of being able to generate vibrations.
