The following is a description of the case where the direction changing device of the present invention is applied to a tray assembling device for thin pieces. Figure 1,
2 shows the front end of the line of the tray assembling apparatus, FIG. 1 is its side view, and FIG. 2 is its plan view. A known slicer S is provided in contact with the front end of the apparatus (FIG. 1), where a block-shaped meat piece is sliced into thin pieces, and the thin pieces are conveyed by a handling device (not shown) of the tray assembling device. Can be placed on top.

The conveyer conveys the vertically long conveyer bases 2 provided at regular intervals by the chain 12 arranged along the parallel mount 11 (FIG. 3) (arrows in FIG. 1). The sliced thin piece M is placed on the surface 2. Each of the left and right chains 12 is suspended on a sprocket 14 (FIG. 3) of a support shaft 13 provided at the front end of the pedestal 11, and the support shaft 13 is provided on the lower stage of the pedestal 11.
It is rotationally driven by hanging the belt from No. 5.

4 to 6 show the detailed structure of the carrier table 2, FIG. 4 is a plan view seen from above, FIG. 5 is a front view, and FIG. 6 is a plan view seen from below. As shown in FIG. 5, the carrier 2 is composed of a long plate-shaped substrate 21 arranged in a horizontal posture, a support plate 22 having the same shape and located above it, and an operation plate 23 located below. There is. And the substrate 21
Is the lower surface of both ends (only one end is shown).
The above-mentioned mount 11 connected to the chain 12 guided by 1.
Move up. The operation plate 23 and the support plate 22 are fixed to the upper and lower ends of the rotating shaft 24 which is supported by the moving substrate 21 so as to penetrate therethrough.
The upper support plate 22 also turns.

A large number of support pieces 25 are provided upright on the support plate 22 at equal intervals in the longitudinal direction. These supporting pieces 25 are formed by forming a metal round bar into a T shape, and have a center leg portion 251.
The horizontal portion 252 extends in the width direction of the support plate 22 (vertical direction in FIG. 4) and is larger than this. Guide rollers 26 are provided on the lower surfaces of both ends (only one end is shown) of the operation plate 23.
A guide plate 16 provided on the gantry 11 contacts the inside 6 from the inside to prevent the operation plate 23 from turning.

That is, as shown in FIG. 2, a pair of left and right (upper and lower in the figure) guide plates 16 are disposed inwardly of the chain 12 in parallel with the front end of the line of the assembling device. Since the guide plates 16 are in contact with the guide rollers 26 of the operation plate 23, the support plate of the carrier 2 is positioned with its longitudinal direction oriented in the direction orthogonal to the laying direction of the chain 12, Move in the state.

The moving carriage 2 with the thin piece M placed thereon passes beneath the imaging device 31 provided above the center of the gantry 11. The image pickup device 31 is connected to an image processing device (not shown) (for example, trade name color selector ER3VC and trade name image checker 30P manufactured by Matsushita Electric Works Ltd.),
This image processing device determines in which of the widthwise directions (that is, the moving direction of the support plate 22) the white fat portion of the thin piece M occupies a large area, and based on the determination result, the backing plate described below. Activate. The imaging device 31
A ring-shaped illuminator 32 is provided immediately below.

That is, the backing plates 33A and 33B are provided at the left and right positions of the pedestal 11 near the end of the guide plate 16 as shown in FIG. 2, and normally located along both side edges of the pedestal 11 as shown in the figure. There is. Each of the backing plates 33A and 33B is a long plate body whose tip is inclined outward and gradually becomes narrower, and the inner edge of the base end is rotatably coupled to the support shaft 331.

However, for example, when the fat portion of the thin piece occupies a large area on the front side in the moving direction, the contact plate 33B is rotated inward as shown by the chain line by a drive mechanism (not shown). To be After the guide roller 26 of the carrying table 2 that is pulled by the chain 12 moves away from the guide plate 16 and becomes freely rotatable, the side edge of the inwardly turned contact plate 33B contacts the guide roller 26. Contact. Then,
On the side where the contact plate 33B abuts, the movement of the guide roller 26 in the advancing direction is hindered, so that the operation plate 23 (see FIG. 5) swivels in the clockwise direction as a whole, and the thin piece M is placed accordingly. The support plate 22 also pivots clockwise as shown.

In this way, the operating plate 23 and the supporting plate 22 which rotates together with the operating plate 23 are swung by the abutting plate 33B until the longitudinal direction thereof is oriented in the traveling direction, and the side having a lot of fat and oil is the front side (see FIG. 2). It is positioned on the lower side) and sent to the next folding process. At this time, the operation plate 23, which has finished the direction change, is positioned at the front and rear of the guide roller 26.
However, the posture change is restricted by entering between the narrow parallel guide plates 17.

Contrary to the above, when the fat portion of the thin piece M occupies a large area on the rear side in the moving direction, the contact plate 33A is rotated inward instead of the contact plate 33B. Then, the support plate 22 is turned counterclockwise as shown by the chain line in the figure, and in this case as well, the side with a lot of fat and meat becomes the front side and is sent to the next first folding step.

In the first folding step, as shown in FIGS. 7 and 8, two folding devices 4A and 4B are provided at the front and rear, and on the support plate 22 which sequentially passes in the longitudinal direction in the traveling direction. The thin pieces M are alternately folded by the front and rear folding devices 4A and 4B to be folded at predetermined positions.

Each folding device 4A, 4B is a servo motor 41.
It has a rod-shaped carriage 42 that is moved in the width direction of the conveyor 1 by means of, and extends downward in the carriage 42 (FIG. 8).
A pair of inner and outer compressed air pipes 43 and 44 are provided. That is, both ends of each of the compressed air pipes 43 and 44 are located on the carriage 42, and compressed air is supplied to the compressed air pipes 43 and 44 from a flexible air supply pipe (not shown).

The middle portion of each compressed air pipe extending downward extends below the support plate 22 of the carrier 2 (FIG. 8) and spreads horizontally horizontally along the carrier 1, and then the carrier 1 of the carrier 1 moves. It is bent at a right angle inward in the width direction, has a substantially U shape in a plan view (FIG. 7), and projects toward the support plate 22. A large number of air blow-out holes (not shown) are provided on the upper peripheral surface at the intermediate portions of the compressed air pipes 43 and 44 inside and outside which project in a similar U-shape and are directed upward from these air blow-out holes. Compressed air is blowing out.

The folding rod 45 extends along the intermediate portion of the outer air pipe 44, at a position closer to the support plate 22 than this, and slightly above the thin piece M (FIG. 8) to the rear in the longitudinal direction of the transport conveyor 1. The position of the folding bar 45 is determined according to the output signal from the image processing device which has detected the distribution of the fat and oil portion.
Is moved so that it is positioned near the boundary between the fat part and the lean part.

When the thin piece M placed on the support plate 22 reaches the folding rod 45 positioned at a predetermined position, it is located in front of the folding rod 45 (lower side in FIG. 7). When the compressed air is blown from below to the fat portion, the fat portion is blown up around the folding rod 45 and folded on the lean portion. The folding bar 45 is relatively extracted from the thin piece M as the support plate 22 moves. Thus, the thin piece M in which the fat portion extending in the longitudinal direction is folded on the lean portion proceeds to the next second folding step.

As shown in FIG. 9, the second folding step comprises a turning positioning device at the front stage and a folding device 5 at the rear stage.
The swivel positioning device has a wide parallel guide plate 18, and one side of the parallel guide plate 18 is forward (left side in the drawing).
An extending portion 181 extending obliquely inward is formed, and is located at a distance from the end of the narrow parallel guide plate 17 in the first folding step.

However, after the guide roller 26 of the operation plate 22 of the carrier table 2 which has passed the first folding step with the longitudinal direction oriented in the moving direction, the guide roller 26 on the front side is removed from the parallel guide plate 17. Contact the extending portion 181 of the parallel guide plate 18. As a result, the front guide roller 2
6 moves outward along the extending portion 181, and along with this, the operation plate 23 (that is, the support plate 22) is swung counterclockwise as shown by the chain line in the figure, and its longitudinal direction is changed. Change the direction so that it is orthogonal to the moving direction. In this state, both guide rollers 26 of the operation plate 22 come into contact with the outer side surfaces of the parallel guide plate 18, the posture of the support plate 22 is fixed, and the process proceeds to the next folding device 5.

In the folding device 5, a pair of support bases 52A and 52B, which are movable by servo drive in the width direction of the conveyor, are mounted on a base 51 provided across the conveyor 1.
Is provided, and a support arm 53 that is bent in an inverted L-shape extends rearward (to the right in the drawing) along the conveyor 1 from each of the support bases 52A and 52B. The tips of the support arms 53 bent inward are coupled to the guide pieces 54, and the guide pieces 54 are
It is movable along a rod-shaped guide body 55 that is installed in parallel with the support bases 52A and 52B. Each of the above support bases 52
Further, folding bars 56 extend rearward along the conveyor 1 from the side opposite to the installation position of the support arms 53, and these folding bars 56 are close to the thin piece M placed on the support plate 22. It is located just above it.

A rotating arm 57 is provided by rotatably connecting the inner end to each of the supporting arms 53, and a plurality of compressed air pipes 58 are provided on these rotating arms 57 toward the front along the conveyor 1.

3 and the folding rod 56, and is located between the support pieces 25 (see FIGS. 4 and 5) immediately below the thin piece M, and has a large number of air outlet holes (not shown) on its upper peripheral surface. ) Is provided, and the compressed air is blown upward from these air outlets. The rotating arms 57 are rotated by a drive cylinder 59 provided integrally with the guide piece 54.

Therefore, both the support bases 52A and 52B are
The fold rods 56 extending from the fold rods 56 maintain a space equal to the width of the tray in which the thin pieces M are packed, and the fat distribution in the longitudinal direction of the thin pieces M determined by the image processing apparatus causes the space between the fold bars 56. So that the fat area is the smallest,
Its position is controlled.

When the thin piece M placed on the support plate 22 of the carrier 2 reaches the front of the folding bar 56 and the compressed air tube 58 thus positioned, the folding bar 56 moves outward from each folding bar 56. The compressed air hits both ends of the thin piece M located. In this state, when each rotating arm 57 is rotated upward around its inner end, the end of the thin piece M is blown up so as to wind around the folding rod 56 and folded over the middle portion of the thin piece M. To be The thin piece M whose both ends are folded is moved to the rear by passing below the guide body 55 by the conveyor 1, and sent to the next transfer step.
