Description

[Detailed description of the invention] The present invention relates to an apparatus for changing the posture of an article.

Generally, when an article is transferred from a specific position, such as an article loading position, to another distant position, such as an article unloading position, especially on an article manufacturing line or a shipping line in a factory, the posture of the article is changed and then transferred. There is often a request to send the product to the process. In such cases, an index table or the like is installed at the transfer start position or transfer end position to change the posture of the article at the desired indexing angle, but this is done in addition to the transfer process. This means that a posture change step is required before or after the transfer step, which has been a serious obstacle to shortening the time in the article handling step.

The present invention has been devised in view of these difficulties, and an object of the present invention is to shorten process time by simultaneously performing required posture changes during transport of articles.

In order to achieve this object, the apparatus for changing the posture of an article according to the present invention includes a turntable rotatably disposed on a cart running on a rail, an article storage means attached to the turntable, and the turntable being moved as appropriate. It is characterized in that it is configured to be rotated by a desired indexing angle by a driving means.

Next, a preferred embodiment of the apparatus for changing the posture of an article according to the present invention will be described in detail with reference to the accompanying drawings. In the embodiment shown in FIGS. 1 to 4, the article handled by this apparatus is a rectangular parallelepiped box like a sheep's package, and the posture 1l-1 to be changed is that with respect to the feeding direction of the article. Although the angle is 90 degrees, it goes without saying that the shape of the article and the angle of attitude change are not limited.

FIG. 1 is a plan view showing a schematic configuration of an apparatus according to the present invention, and FIG. 2 shows a longitudinal section taken along the line It-M in FIG. The gist of the present invention is that a ring-shaped turntable 12 is rotatably disposed on a traveling carriage 10 in the figure.
2 is configured to be rotated by 90 degrees by means of a guide rail 14 and a cam plate 16 connected thereto, so this configuration will be mainly described below along with surrounding ancillary structures.

1 and 2, there is a point A where an article 18, which will be described later, is carried in from below by a lifter 20, and a point A where the vaginal article 18 is transferred horizontally by a predetermined distance f, and the supply posture is 90.
There is a point B which is turned and transported downwards, and a pair of parallel upright side walls 24 supported by a number of upright columns 22 are located outwardly from these article entry points A and article removal points B.
．． 24 are arranged. A beam member 26 is extended between the ends of each of these upright side walls 24 to form a rigid frame structure as a whole, and inside each upright side wall 24 there is a support for running a cart 10, which will be described later. A rail 28 is arranged so as to protrude in the horizontal direction. That is, trolley 1
As shown in FIG. 1, 0 is constructed as a rectangular frame consisting of opposing side walls 32 and 32 that respectively support the wheels 30, and beam members 34 and 34 that are hung between these side walls. By placing the wheels 30 on the rails 28, the trolley 10 freely travels on the rails 28, 28 in the section between the article loading point A and the article unloading point B in FIG. It is preferable that the wheels 30 be disposed below the rails 28 as shown in FIG. 3 to avoid the risk of the bogie 10 derailing from the rails 28.

In this embodiment, a pneumatic cylinder is used as the driving source for the trolley 10, but other suitable rotation sources may be used to drive the wheels 30 by a chain or pulley, or an electric motor may be built into the trolley 10. It may also be a so-called self-propelled trolley. When using a pneumatic cylinder as a linear actuator, in this embodiment, since the travel distance of the truck 10 is long, a single cylinder does not have a sufficient stroke length.

For this reason, as shown in Fig. 1, two pneumatic cylinders 3
It is recommended to arrange the cylinders 6a and 36b in an aligned manner and to connect the cylinder bottoms to each other. In this case, the piston rod 38 of one pneumatic cylinder 36a
The distal end is secured to a bracket 42 provided on a support member 40 that extends horizontally overhanging the upright side wall 24;
The piston rod 44 of the still other pneumatic cylinder 36b
is connected and fixed to one beam member 34 of the truck 10 via a connecting rod 46, as shown in FIG. In addition, the above 2
The cylinder bottoms of the two pneumatic cylinders 36a, 36b are connected by a rectangular connecting member 48, which slides on two guide rails 50, 50 arranged at right angles to the beam member 26. It is now possible to do so. Therefore, if the two cylinders 36a and 36b are energized sequentially or simultaneously to extend each piston rod 38, 44 from each cylinder tube, the cart 1o will be moved from the solid line position (article delivery point B) to the dashed line position. (Goods delivery point A)
It runs on the rail 28 toward the trench cylinder 36a.
, 36b, each piston rod 38.4
4 is retracted into each cylinder tube and the stand ji(,i
It is understood that the vehicle o also travels in the opposite direction.

As shown in FIG. 1, a ring-shaped turntable 12 is rotatably disposed on the frame-shaped truck 10. As shown in FIG.

That is, a virtual regular hexagon is assumed on a plane including the beam members 34, 34 of the pair of bogies 1001 and the pair of girder members 52, 52 installed between these beam members, and each vertex position of the virtual regular hexagon is A ring-shaped turntable 12 is attached to the rollers 54, and the rollers 54 are rotatably and vertically supported.
The turntable 12 is rotatably supported on the cart 10 by bringing the flange portions of the turntable 12 into contact with the flange portions of the turntable 12 .

In this case, as shown in FIG. 3, an annular piece 56 is disposed on the back side of the turntable 12 and
It is preferable to configure each row 254 to be sandwiched between the lifter portion and the annular piece 56, since the rotary table 12 will not fall off from the roller 54.

On the back side of the turntable 12, pillars 58 made up of four hexagonal bars are suspended and fixed upright in proximity to the circular through hole, and an article storage case 59, which will be described later, is configured at the lower end of these pillars 58. A rectangular ceiling plate 60 is fixed, and side plates 62 are arranged and suspended from this ceiling plate 60. This side plate 62 is used for the purpose of collectively storing multiple rows of multi-layered articles 10 and transporting them from the article loading point A to the article carrying out point B. Therefore, the ceiling plate 62
The dimensions of the zero and ill plates 62 are appropriately selected depending on the overall dimensions of the article to be graded.Furthermore, on the upper surface of the turntable 12, a support member 64 made of an L-shaped angle member is arranged. A vertical plate 66 is fixed to this support member 64 as shown in FIG. has been done. Said pair of platans) 68.6
A grooved rail 7o is vertically disposed in the space formed between the spaces 8 and 8, and the lower end of this rail 70 is connected to the ceiling plate 6 of the article storage case 59, as shown in FIGS. 2 and 3.
It extends into the case through a 0 KG-sized through hole, and its end is fixed to a presser plate 72 within the case. Said grooved rail 70, as shown particularly clearly in FIG.
Rows 27 are arranged on the vertical plate 66 in pairs at predetermined intervals, one above the other at a predetermined interval.
4, it is held in such a way that it can be raised and lowered via a groove, and is biased to go up and down by a pneumatic cylinder 76 that is disposed parallel to this rail 70. That is, as shown in FIG. 2, a double-acting pneumatic cylinder 76 is fixed upside down perpendicularly to the bracket 68, and a piston rod 78 of this cylinder 76 is fixed to the rail 70 via a connecting member 80. .

Therefore, when the pneumatic cylinder 76 is energized, the piston door 8 extends from the cylinder tube, thereby vertically lowering the rail 70 and lowering the retainer plate 72 fixed to the end of the rail within the case 59. That will be understood. Further, when the cylinder 76 is reversely biased, the rail 70 moves vertically upward and backward. After all, the four rollers 74 holding the rail 70 function as guide rollers for always raising and lowering the rail at a fixed position.

Next, as shown in FIG. 1, in the traveling section of the truck 10, a guide rail 14 is provided inside one of the upright side walls 28, and a cam groove 82 is provided in the downward direction of the kite rail 14.
Then, the roller 84 of the cam plate 16 fixed to the turntable 12 is fitted (FIG. 3), and the turntable 12 is moved to the 9th position.
It can be rotated by 0 degrees. That is, the cam groove 82 extending in the guide rail 14 extends parallel to the rail 28, and is curved to form a quadrant arc with a center angle of 90° near the point where it reaches the article delivery point B. are doing. The row 2 of the cam plate 16 is inserted into the cam groove 82.
84 is rotatably fitted, if the truck 10 is forced to travel to the left in FIG. If the cart 10 is forced to travel rightward from the dotted line position at the article loading point A, the turntable 12 will be rotated 90° clockwise near the end of its travel. That will happen.

This turntable 12 moves 90 times as the trolley 10 moves.
The state of rotation is shown in FIG.

Next, as shown in FIG. 2, a vertically movable lid 20 is disposed below the article loading point A, and a rectangular parallelepiped-shaped article 18 (in this embodiment) that was stacked in multiple rows in the previous process 4 rows and 4 layers) are placed in alignment on this lifter 20 and can be lifted vertically. Further, a bed 86 functioning as an article conveyance path is horizontally disposed between the article carry-in point A and the article take-out point B and at a level slightly below the lower opening end of the article storage case 59. Furthermore, a pair of guide plates 88 and 88 are provided at the article unloading location B at the same level as the bed 86, and sheet corrugated cardboard blanks 9 for article packaging are passed over the guide plates.
0 is arranged to arrive horizontally. Further, below the article delivery location B, a baquim cup 92 is provided on the upper surface, and a lid 94 is disposed such that it can be raised and lowered. In FIG. 1, reference numerals 96a to 96c indicate limit switches for detecting the position of the cart, and in FIGS. 2 and 4, 98 indicates the upper and lower limits i of the grooved rail 70.
Shows the IJ mitswitch for tk detection. Further, 100a to 100c14 are vacuum valves for energizing and deenergizing each cylinder, and 102 is a cylinder speed controller, respectively.

Next, the operation and effect of the device according to the present invention configured as described above will be explained. In FIG. 2, the two cylinders 36a and 36b are energized sequentially or simultaneously to cause the trolley 10 to travel leftward on the rail 28, and stop and wait at a position above the article loading point A, as shown by the broken line. I'll let it happen. Furthermore, if the assembled articles 18 stacked in 4 rows and 4 layers are placed on the girder 20 and the girder 20 is raised, the aggregated articles 18 will be placed in the article storage case above which is waiting to be opened. Started to invade 59 and put lifter 20 on bed 8
By raising it to the same level as 6 and stopping it, the collected articles 18 are stored in the case 59 mentioned above.

Next, when the cylinders 36a and 36b are reversely energized, the truck 10 starts to run horizontally to the right from the broken line position in FIG.
The article storage case 59 hanging down from the case 59 also moves to the right, and the collected articles 18 stored in the case 59 are transferred from the table surface of the lifter 20 to the upper surface of the bed 86 in the stored state. It is transferred on the bed 86 with the cart running. After the articles 18 are transferred from the lifter 20 in this manner, the lifter 20 is lowered and moves on to the work of placing the next collected article again. Also, at this timing, the sheet-like corrugated cardboard blank 90 with the packing box unfolded is fed onto the guide plate 88°88, and another lid 94 provided at the article delivery point BK is fully raised, and the lifter 94 (rj) The vacuum cup 92f is brought into contact with the lower surface of the cardboard blank 90, and the bed 86
The corrugated pole blank 90 is held horizontally by vacuum suction at the same level as the carriage (and the case 59) to arrive.

Returning to FIGS. 1 and 5, when the trolley 10 travels to the right, the rollers 84 of the cam plate 16 fixed to the turntable 12 travel while following the cam grooves 82 of the guide rail 14, but the cam grooves Since the cam operation is not performed until just before the turntable 82 begins to curve, the turntable 12 remains stationary on the carriage 10.

However, when the roller 284 of the cam plate 16 approaches the curved portion of the cam groove 82, the roller 84 curves in the traveling direction following the cam groove 82, as shown in FIG. In order to apply rotational force to the turntable 12, the turntable 12 begins to rotate clockwise and moves toward the article delivery side P
When the cart 10 stops at hB, the turntable 12 has completed its 90° rotation. That is, as can be seen from FIG.
Case 5 containing article 18 moves to the right.
It can be seen from FIG. 2 that the article 18 passes through the bed 86 and is placed on the cardboard blank 90 since the article 9 also travels.

In this way, when the cart 10 returns to the article delivery point B with the article 18 stored in the case 59, when the upright cylinder 76 is energized, the rail 70 is vertically lowered while being held between the rollers 74. , the presser plate 72 fixed to the end of the rail begins to push out the collected articles 18 stored in the case 59 from the case 59. In addition, the corrugated pole blank 90 and the article 18ff: supporting rod 7ter 94
2, the article 18 is completely pushed out of the case 59 and transported to the next process. At this time, by providing an appropriate guide plate (not shown) around the descending locus of the star 94,
The cardboard blank 90 is appropriately folded during its descent, and the article 18 is simultaneously packaged into a box.

When the article 18 has been unloaded, the two cylinders 36a
, 36b are energized again, and the trolley 10 starts traveling toward the article loading location A. On the way, the turntable 12 (and the article storage case 59 ) is rotated 90° counterclockwise to repeat the cycle of carrying in the article, transferring it, changing its position, and then taking it out. In addition, in this example,
The turntable 12 is designed to rotate 906 times near the end of the travel of the trolley 10 on the article delivery side.
By changing the mounting position of the guide rail 14 rotationally symmetrically in the figure, the turntable 12 can also be rotated 90 degrees immediately after the cart starts traveling on the article loading side.

Further, as a means for rotating the turntable 12 to a predetermined indexing angle, it is possible to adopt a structure other than the above-described combination of a cam plate and a cam groove extending in a guide rail. It is possible.

For example, a ring gear may be carved on the outer periphery of the turntable or the inner periphery of the circular hole, and a pinion gear connected to the output shaft of the reducer may be engaged with this ring gear to rotate the turntable, or a hydraulic motor may be used. An oscillating actuator, which is one of the glazes, may be connected to the central rotating shaft of the turntable so that it can be directly rotated. In the latter case, a swing type actuator using a ring piston is preferable because it can rotate by a central angle of 90°. Furthermore, various mechanisms are used, such as biasing with a linear actuator such as a full cylinder around the turntable, or a combination of a rack and pinion.

In addition, below the turntable 12, there are four pillars 5.
In this embodiment, the article storage case 59 suspended and supported by the item storage case 59 cannot be moved up and down, but it can be configured to move up and down as necessary in combination with an appropriate lifting mechanism. Good too.

As explained in detail above, according to the article attitude changing device according to the present invention, a turntable is rotatably disposed on the traveling cart, a case for storing the article is provided on the turntable, and an appropriate means is provided. By configuring the turntable to rotate, the attitude of the article can be changed to a desired indexing angle. Therefore, it can be suitably used, for example, when it is desired to change the posture of the article and send it out while transferring the article from the carry-in position to the carry-out position, and the process time can be significantly shortened. Furthermore, since the structure is simple, it can be manufactured at low cost and easily, and it has many useful advantages, such as being less likely to break down.

Although the apparatus according to the present invention has been described above with reference to preferred embodiments, the present invention is not limited to the illustrated embodiments, and various mechanisms for rotating the turntable can be used as described above. Modifications are possible and are encompassed by the present invention within the spirit of the invention.
