Hereinafter, a corrugated cardboard support device and a transport device according to embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a plan view showing an overall configuration of a transport facility for transporting a cardboard DB.
The transport equipment is manufactured from a corrugated cardboard transport path L1 that transports the corrugated cardboard DB stacked on the pallet PL together with the pallet PL, a box making machine R that continuously creates boxes from the corrugated cardboard DB, and a carry-out position Go of the corrugated cardboard transport path L1 A transport device 1 that transports the cardboard DB to a carry-in position Gi above the box R is provided.
The cardboard transport path L1 includes a drive unit (not shown), and transports the cardboard DB along the pallet PL in the transport direction A (longitudinal direction). Note that the leading end of the cardboard transport path L1 is the carry-out position Go.

  The box making machine R includes a box making main body R1 for creating a box, and four struts R2 and R3 having an L-shaped cross section extending in a vertical direction from the upper surface of the box making main body R1. Further, the box making machine R is configured to store the corrugated boards DB on the flat plates in a rectangular area defined by the four columns R2 and R3. And it sends to the box-making main-body part R1 in order from the corrugated board DB piled down, and, thereby, a box is continuously made from the corrugated board DB on a flat plate.

The transport device 1 includes a main body (moving mechanism) 2 having a driving unit such as a motor, a cardboard support device 10 that supports a corrugated cardboard DB on a flat plate, and an arm that connects the main body 2 and the cardboard support device 10 ( Moving mechanism) 6.
The main body 2 is configured to be capable of turning in the horizontal direction on a horizontal plane.
The arm 6 includes a base end arm part 3 connected to the main body part 2, a front end arm part 4 connected to the cardboard support device 10, and a rotating shaft part that connects the base end arm part 3 and the front end arm part 4. And 5. The proximal arm 3 is connected to the main body 2 so as to be rotatable in the vertical direction, and the distal arm 4 is connected to the cardboard support device 10 so as to be rotatable in the vertical direction. The rotating shaft portion 5 extends in the short direction of the proximal end arm portion 3 and the distal end arm portion 4, so that the proximal end arm portion 3 and the distal end arm portion 4 can rotate in the vertical direction with respect to each other. It is connected to.
Under such a configuration, the main body 2 rotates and the arm 6 is driven by the drive unit, whereby the proximal arm 3 and the distal arm 4 are rotated vertically, whereby the cardboard support device 10 is It is designed to move up, down, left and right.

As shown in FIG. 2, the cardboard support device 10 includes four suction portions (support portions) 11a and 11b and a connection frame 12 that connects the four suction portions 11a and 11b.
The distal arm 4 is connected to the connection frame 12.
The suction portions 11a and 11b are arranged above the four corners of the corrugated cardboard DB on the flat plate, respectively, and suck the air, thereby not only supporting the corrugated cardboard DB but also discharging the air while supporting the corrugated cardboard DB. The cardboard DB is released.
These suction portions 11a and 11b are composed of suction base end portions 111a and 111b extending downwardly from the connecting frame 12, and suction tip end portions 112a and 112b connected to the tips of the suction base end portions 111a and 111b. And.

The suction base end portions 111 a and 111 b are set to have the same size and are fixed to the connecting frame 12 symmetrically.
The suction tips 112a and 112b are extended in a straight line in the vertical direction, and their lower ends are in contact with the cardboard DB and suck air to support the cardboard DB. The longitudinal dimensions of the suction tips 112a and 112b are different from each other. That is, the longitudinal dimension of the suction tip portion 112a is longer than the longitudinal dimension of the suction tip portion 112b. More specifically, in the orthogonal direction M orthogonal to the transport direction A, the longitudinal dimensions of the two suction tip portions 112a far from the main body 2 are set to the same size and more than the suction tip portion 112b. On the other hand, the longitudinal dimensions of the two suction tips 112b closer to the main body 2 are set to the same dimension and shorter than the suction tips 112a. Therefore, the distance dimension k1 in the vertical direction from the connection frame 12 to the tip of the suction tip part 112a is longer than the distance dimension k2 in the vertical direction from the connection frame 12 to the tip of the suction tip part 112b.
In other words, the height dimension h1 of the suction tip portion 112a with respect to the carry-out position Go is shorter than the height dimension h2 of the suction tip portion 112b with respect to the carry-out position Go. Therefore, the respective height positions of the suction tip portion 112a and the suction tip portion 112b with respect to the carry-out position Go are sequentially increased from one direction M1 in the orthogonal direction M to the opposite direction M2.

The suction tips 112a and 112b are configured to be extendable and contractable in the longitudinal direction (vertical direction). Furthermore, the suction tips 112a and 112b are provided with springs (elastic members) (not shown), and bias the suction tips 112a and 112b downward. As a result, in the natural state, the suction tip 112a is arranged at an inclined position Q1 whose lower end is located below the lower end of the suction tip 112b due to the biasing force of the spring. On the other hand, when the suction tip 112a is pushed upward from its lower end, the suction tip 112a is contracted against the biasing force of the spring, and is arranged at a horizontal position Q2 having the same height as the lower end of the suction tip 112b. Yes.
The natural state refers to a state where an external force other than gravity is not applied, and refers to a state where the corrugated board support device 10 is lifted from the connection frame 12 and the suction tips 112a and 112b are suspended in the air.

Next, the operation of the cardboard support apparatus 10 transport apparatus 1 in the present embodiment configured as described above will be described.
It is assumed that the cardboard support device 10 is disposed above the carry-out position Go of the cardboard transport path L1.
First, the pallet PL on which the cardboard DBs are stacked is transported in the transport direction A on the cardboard transport path L1, and the pallet PL stops at the unloading position Go. Then, the cardboard support device 10 moves downward via the arm 6, and the suction tips 112a and 112b contact the four corners of the cardboard DB, as will be described later. Further, the corrugated board DB is supported by the suction tips 112a and 112b sucking air.

The cardboard support device 10 moves upward while supporting the cardboard DB. As a result, the cardboard DB is lifted upward. From this state, the main body 2 rotates 90 °, and the cardboard support device 10 is disposed above the box making machine R while supporting the cardboard DB. Then, when the suction tips 112a and 112b discharge air, the corrugated board DB is released and falls due to its own weight, and is loaded at the loading position of the box making machine R. Further, the cardboard support device 10 is returned to the upper position of the carry-out position Go by the reverse operation. Then, by repeating these conveying operations, the cardboard DB is continuously conveyed from the unloading position Go to the loading position Gi.
The cardboard DBs stacked at the carry-in position Gi are sent to the box making machine R in order from the bottom, and boxes are continuously made.

Here, the details of the operation of transporting the cardboard DB from the carry-out position Go to the carry-in position Gi will be described for the cardboard support device 10 and the transport device 1 in the present embodiment.
As shown in FIG. 3, when the cardboard DB is arranged at the carry-out position Go, the cardboard support device 10 is arranged above the cardboard support device 10. At this time, the positions of the suction tips 112a and 112b are inclined positions Q1.
Further, the cardboard support device 10 moves downward. Then, the tip of the suction tip 112a first comes into contact with the top cardboard DB. When the cardboard support device 10 further moves downward, the suction tip 112a is pushed upward by the reaction from the cardboard DB, and contracts against the urging force of a spring (not shown). As shown in FIG. 4, the tip of the suction tip 112b eventually comes into contact with the cardboard DB, and the four suction tips 112a and 112b are arranged at the horizontal position Q2. Further, the downward movement of the corrugated board support device 10 is stopped in a state where the four suction tips 112a and 112b are contracted against the biasing force of a spring (not shown).

  Further, when air is sucked from the suction tips 112a and 112b, the suction tips 112a and 112b become negative pressure, whereby the cardboard DB is sucked and supported by the suction tips 112a and 112b. Then, when the cardboard support device 10 moves upward, the cardboard DB is lifted as shown in FIG. At this time, the suction tips 112a and 112b are extended by a biasing force of a spring (not shown) and are arranged at the inclined position Q1. That is, the height positions of the suction tip portion 112a and the suction tip portion 112b with respect to the carry-out position Go increase in order from one direction M1 in the orthogonal direction M to the opposite direction M2. Thereby, in a natural state, the corrugated board DB is supported in an inclined direction (in a direction gradually increasing from one direction M1 to the opposite direction M2). Therefore, the height position of the side DB1 in the one direction M1 of the cardboard DB is lower than the side on the opposite side.

  Then, the cardboard support device 10 turns 90 °, and the cardboard DB is arranged above the carry-in position Gi as shown in FIG. Then, the suction tip portions 112a and 112b discharge the air, thereby releasing the cardboard DB. Therefore, the cardboard DB falls due to its own weight. At this time, since the cardboard DB is released in an inclined state, the cardboard DB falls in one direction from the side part DB1 having a low height position (since it has rotated 90 °, one direction changes from M1 to the conveyance direction A). Go. Since the support R2 is provided in one direction (conveying direction A), the cardboard DB is stopped from moving in one direction (conveying direction A) by contacting the support R2, and dropped in the vertical direction. To go. Then, the cardboard DB is arranged at the carry-in position Gi, and is similarly stacked continuously at the carry-in position Gi.

As described above, according to the cardboard support device 10 and the conveyance device 1 in the present embodiment, the cardboard DB is released in a state where the cardboard DB is inclined in a certain direction. Therefore, even if the cardboard DB is warped or deformed, such as S-shaped. The cardboard DB can be dropped in one direction. Therefore, the cardboard DB can be accurately conveyed to the carry-in position Gi.
In addition, since the column R2 is provided in the direction (one direction) in which the cardboard DB is dropped, the movement in one direction of the cardboard DB can be stopped, and the one-way ends of the cardboard DB are aligned. It can be conveyed with higher accuracy up to the carry-in position Gi.

Further, since the height position of the suction tip portion 112a and the height position of the suction tip portion 112b are matched to a position that increases sequentially from one direction toward the opposite direction, the corrugated board DB is inclined. Can be supported and released reliably.
Further, the suction tip portions 112a and 112b are configured to be extendable and contracted, and are biased downward by a spring and are arranged in the inclined position Q1 in a natural state, so that the cardboard DB is easily inclined. Therefore, it is not necessary to control the discharge amount and timing of air from the suction tips 112a and 112b.
Further, since the suction tips 112a and 112b are configured to be changeable between the inclined position Q1 and the horizontal position Q2, the suction tips 112a and 112b are arranged horizontally by being arranged at the horizontal position Q2. In addition to being able to easily support the corrugated cardboard DB, the corrugated cardboard DB can be easily tilted by disposing the suction tips 112a and 112b at the tilted position Q1 when released.

The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, when the corrugated board DB is inclined, the side of the corrugated board DB is arranged at the lowest position. However, the present invention is not limited to this, and as shown in FIG. It may be arranged in. That is, the longitudinal dimension k1 of the suction tip 112a is the longest, the longitudinal dimension k2 of the suction tips 112b1 and 112b2 is the next shortest, and the longitudinal dimension k3 of the suction tip 112c is the shortest. . In other words, as viewed from the side, the height positions of the suction tips 112a, 112b1 (112b2), 112c may increase in order from the conveyance direction (one direction) A toward the opposite direction. That is, the height position of the suction tip portion 112a is the lowest, and the height position is sequentially increased from the suction tip portion 112a to the suction tip portion 112b1 (112b2) and the suction tip portion 112c as the distance from the suction tip portion 112a increases. Is configured to be high. As a result, when the cardboard DB is supported, the cardboard DB can be inclined with the corner DB2 of the cardboard DB being at the lowest position, so that the area of the lowermost portion of the cardboard DB can be reduced, and the lower portion of the cardboard DB is in the lower position. The air resistance of the part can be reduced. Therefore, the cardboard DB can be dropped to the carry-in position Gi with higher accuracy.
Note that the longitudinal dimensions k2 of the suction tips 112b1 and 112b2 may be the same or different from each other. However, it goes without saying that the longitudinal dimension k2 is set shorter than the longitudinal dimension k1 and longer than the longitudinal dimension k3.
In FIG. 7, reference numeral 11c indicates a suction portion, and reference numerals 111b1 and 111c indicate suction base end portions.

  The suction tips 112a and 112b support the four corners of the cardboard DB. However, the present invention is not limited to this, and the support positions can be changed as appropriate. For example, as shown in FIG. 8, the suction portions 11a are arranged symmetrically with respect to the virtual line (diagonal line) T passing through one corner DB2 of the cardboard DB and the opposite corner DB3, and the virtual line T is sandwiched between them. You may make it arrange | position the suction part 11b symmetrically. Accordingly, as shown in FIG. 8, the suction tips 112a, 112b having different longitudinal dimensions are provided as shown in FIG. 8 without providing three or more types of suction tips 112a, 112b1, 112b2, 112c having different longitudinal dimensions as shown in FIG. With only these two types, the corrugated board DB can be easily inclined with the one corner DB2 at the lowest position.

Also, the number of suction units may be one or two or more. When one suction part is provided, the tip of the suction part may be inclined so as to be capable of longitudinal rotation. And when attracting | sucking, the said front-end | tip is distribute | arranged to a horizontal direction, and in a natural state, it can be urged | biased by the urging member, and the said front-end | tip can incline. Further, when two or more suction portions are provided, the number may be an odd number or an even number. For example, as shown in FIG. 9, six suction portions 11a, 11b, and 11c can be provided.
Further, the cardboard support device 10 supports one cardboard DB. However, the present invention is not limited to this, and the number of supported cards may be two or more, and can be changed as appropriate. For example, as shown in FIG. 10, the connection frame 12 connects the suction portions 11a and 11b in pairs, and each suction portion 11a and 11b supports the cardboard DB one by one (a total of two). Good. In this case, after one suction part 11a, 11b is arranged at the carry-in position Gi first and the cardboard DB is released, the other suction part 11a, 11b is arranged at the carry-in position Gi to release the cardboard DB. .

One direction when viewed from the side is one direction M1 of the orthogonal direction M and the transport direction A, but is not limited to this, and any one of the horizontal directions when the cardboard support device 10 is viewed from the horizontal direction. Can be changed as appropriate with one direction as the opposite direction and the other as the opposite direction.
Further, although the corrugated board DB is supported in an inclined state, the present invention is not limited to this, and it may be supported in a horizontal state. In this case, when the cardboard DB is released, the suction tip portion may be arranged at the inclined position Q1, or the tip portion of the suction portion may be inclined. Alternatively, at the time of release, air may be discharged first from the suction tip portion 112a, and then air may be discharged from the suction tip portion 112b. That is, by providing a time difference in the discharge of air from the suction tip portions 112a and 112b by the control unit, the cardboard DB can be released in an inclined state.
Alternatively, the cardboard DBs on the pallet PL may be tilted and stacked and lifted as they are.
Needless to say, the above embodiment and the above modifications can be freely combined.
