Description

  The present invention relates to a laying apparatus that lays down a conveyed product conveyed by a conveying means, and more particularly to a device suitable for conveying a packaging bag packed with powder such as resin powder as a conveyed product.

  Conventionally, when a transported product in which powder such as resin powder is packed in a packaging bag is transported by a belt conveyor or the like, for example, after the powder is supplied from above to the packaging bag on the belt conveyor by a hopper or the like, this packaging bag The upper opening is sealed, and this is further transported to a subsequent process by a belt conveyor and loaded on, for example, a pallet. When transporting a transported object in this manner, the transported object on the belt conveyor is laid down for the convenience of work such as loading in a subsequent process.

  As described above, when the conveyed product is laid down manually, it is troublesome to perform it manually. Thus, for example, Patent Document 1 proposes to use a packing jig that turns over the conveyor so as to hold the packaging bag on the conveyor by rotating above the conveyor.

However, especially when a packaging bag filled with powder is laid down, using the packing jig as described above, the shape of the packaging bag after being laid down is distorted, and stable in the subsequent process. It may become impossible to supply. In addition, depending on the capacity of the packaging bag and the weight and density of the powder in the packaging bag, the direction of the packaging bag may fall apart, or the packaging bag may not be able to lie down. In some cases, the packaging bag is caught on the belt conveyor, resulting in clogging of the conveyance.

It can be rotated between 90 degrees toward the 4 side (refer FIG.3 (c) and FIG.4 (a)).

  Moreover, it is also preferable to provide a detection means 31 for detecting that the conveyed product 5 is disposed at a predetermined position in the laying apparatus A. As the detection means 31, for example, a photoelectric sensor (photoelectric switch) that detects that the conveyed product 5 is disposed at a predetermined position with respect to the holding means 2 can be provided. For example, as shown in FIGS. 3 and 4, the photoelectric sensor 31 a is provided on the opposite side of the holding means 2 from the conveying means 4, and the downstream end of the conveyed product 5 matches the downstream edge of the holding means 2. When it is arranged at the position to be detected, the photoelectric sensor 31a detects the presence of the conveyed product 5. Further, when the conveyed product 5 is laid down on the downstream side of the photoelectric sensor 31a and transferred to the downstream side by the transfer means 3 of the apparatus A (see FIGS. 4A and 8C), the transfer is performed. A photoelectric sensor 31b that detects the presence of the object 5 may be provided.

  The usage form of the overturning apparatus A of the conveyed product comprised as mentioned above is demonstrated with reference to the schematic diagram shown to FIG.

  In the illustrated example, the transport direction of the transported object 5 by the transport means 4 is linear, and the upstream transport means 4a and the downstream transport means 4b are provided in series and the transport directions are the same. ing. The operation of the upstream transport unit 4a is controlled independently of the downstream transport unit 4b based on the detection results of the photoelectric sensors 31a and 31b.

  First, the conveyed product 5 such as a packaging bag 5a packed with powder of resin powder or the like is upstream of the position where the laying apparatus A is disposed in the conveying means 4 such as a belt conveyor, and the upstream conveying means 4a. It is conveyed in the horizontal direction (see FIG. 3A). On the upstream conveying means 4a, the packaging bag 5a is arranged in a posture in which the sealed upper opening is located above and rises on the conveying means 4, and the longitudinal direction in plan view is arranged along the conveying direction. Is done. Further, the conveyed product 5 is disposed at a position to be supplied between the holding unit 2 and the pressing unit 7.

  Next, when the conveyed product 5 is disposed between the holding means 2 and the pressing portion 7 and the conveyed product 5 is detected by the photoelectric sensor 31a (see FIGS. 3B and 1A), this detection is performed. Based on the result, the conveyance of the conveyed product 5 by the upstream conveying means 4a is stopped, and the pressing means 7 is operated so that the driving rod 22 of the advance / retreat driving device 21 protrudes, whereby the pressing portion 7 is swung and held. It moves to the means 2 side (refer FIG.3 (c) and FIG.1 (b)). As a result, the conveyed product 5 is pressed by the pressing unit 7, and the bottom thereof is tilted toward the holding unit 2 while being disposed on the conveying unit 4, and is held in a state of being aligned on the holding surface 18. If the holding surface 18 is arranged in an inclined state, the conveyed product 5 is held in a posture inclined along the inclination. At this time, the conveyed product 5 is sandwiched between the holding surface 18 of the holding means 2 and the pressing portion 7. Further, at this time, the upstream conveying means 4a may be operated without being stopped. Even in this case, the conveyed product 5 is engaged with the guide plate 19 of the holding means 2 and is aligned on the holding surface 18. Be placed.

  Here, since the pressing unit 7 presses the conveyed product 5 in the planar contact region 6, it presses a wide area on the surface of the conveyed product 5, and the concentration of the pressing force on the surface of the conveyed product 5 is reduced. It is alleviated and deformation and distortion are less likely to occur in the conveyed product 5. Further, since the roller 9 is provided in the pressing area of the pressing portion 7 as described above, the friction between the pressing portion 7 and the conveyed product 5 is reduced, which also causes deformation and distortion of the conveyed product 5. Occurrence can be suppressed.

  Further, when the angle of the pressing portion 7 is changed by operating the advance / retreat driving device 25 in conjunction with the movement of the pressing portion 7, the angle of the contact region 6 of the pressing portion 7 is changed according to the tilt of the conveyed product 5. The contact area 6 can be maintained in a state where the contact area 6 is in contact with the surface of the transported object 5 in a planar manner, and the contact area 6 is maintained even when the transported object 5 is sandwiched between the pressing portion 7 and the holding means 2. The surface of the conveyed product 5 can be brought into contact with the surface. For this reason, the concentration of the pressing force on the surface of the conveyed product 5 is further relaxed, and the occurrence of deformation and distortion is further prevented.

  Next, the transfer means 3 is operated, and the holding means 2 and the pressing means 1 are rotated by 90 ° together with the gantry 16 in a state where the conveyed product 5 is sandwiched (see FIG. 4A). At this time, the edge of the holding surface 18 of the holding means 2 is disposed above the downstream side conveying means 4b, the conveyed product 5 is transferred to the downstream side conveying means 4b, and the bottom thereof is the downstream side conveying means 4b. The downstream side and the upper side are arranged on the upstream side. Further, when the holding surface 18 is inclined, the downward inclination direction thereof coincides with the conveyance direction by the downstream-side conveyance means 4b, and the conveyed product 5 is disposed so as to be inclined downward with respect to the conveyance direction. Is done. When the conveyed product 5 is transferred by the transfer means 3 in this manner, the presence of the conveyed product 5 is detected by the photoelectric sensor 31b, and the operation of the upstream conveying means 4a is stopped based on the detection result. Resumes its operation.

  Next, by operating the pressing means 1 so that the drive rod 22 of the advancing / retreating drive device 21 is pulled, the pressing portion 7 is swung and moved away from the holding means 2 to be arranged at the original arrangement position. (See FIG. 4 (b)). As a result, the pressing portion 7 is separated from the surface of the conveyed product 5, and the holding of the conveyed product 5 by the holding means 2 and the pressing portion 7 is released. Thereby, the conveyed product 5 is conveyed downstream by the conveying means 4, and when the holding surface 18 is inclined at this time, it smoothly moves to the downstream portion of the conveying means 4 along the inclination. . At this time, the conveyed product 5 is laid sideways and is conveyed in a state where the bottom portion is disposed on the downstream side and the upper portion is disposed on the upstream side. In this way, when the up-and-down direction of the horizontally-fed transported object 5 coincides with the transporting direction by the transporting unit 4, the sealed portion of the upper opening of the transported object 5 may protrude sideways from the transporting unit 4. In addition, it is possible to prevent the transport of the transported object 5 from being obstructed by this part being caught in various places in the transport process.

  Next, the transfer means 3 is actuated to return to the initial state shown in FIG. 3A, and the above operation is repeated, whereby the transport means 4 is sequentially processed with respect to the transported objects 5 being transported sequentially. Can do.

  In such a conveyed product laying apparatus A, by adjusting the length of the drive arm 8 by expanding and contracting the drive arm 8, the height position of the pressing portion 7 can be adjusted. The pressing portion 7 can be arranged at an optimal position for pressing and tilting the conveyed product 5 according to the size, weight, center of gravity position, and the like.

  Further, in the above-mentioned transported object laying apparatus A, the inclination angle of the transported object 5 held by the holding means 2 may be made variable by forming the angle of the holding surface 18 with respect to the horizontal plane so as to be variable. In the example shown in FIG. 5, the support portion 33 extending downward from the lower surface of the holding plate 32 constituting the holding means 2 is orthogonal to the inclination direction of the holding plate 32 at the shaft support portion 34 provided on the gantry 16. It is connected so as to be rotatable around a horizontal rotation axis. In addition, the holding plate 32 and the gantry 16 are connected via an advancing / retracting drive device 39 such as an air cylinder behind the connecting position of the support portion 33 and the shaft support portion 34. At this time, the advancing / retreating drive device 39 is connected at its rear end to the gantry 16 so as to be rotatable around a horizontal rotation axis orthogonal to the inclination direction of the holding plate 32, and the drive rod of the advance / retreat driving device 39 A knuckle 36 is provided at the tip of 35. Further, a connecting portion 37 is provided on the lower surface of the holding plate 32 so as to extend downward behind the support portion 33. The connecting portion 37 and the knuckle 36 are connected so as to be rotatable around a horizontal rotation axis perpendicular to the inclination direction of the holding plate 32. For this reason, by driving the drive rod 35 of the advance / retreat drive device 39 forward and backward, the holding plate 32 rotates around the connection position of the support portion 33 and the shaft support portion 34, and the inclination angle of the holding surface 18 varies. . At this time, the angle of the holding surface 18 with respect to the horizontal plane is formed to be changeable within a range of 0 ° to 30 ° with respect to the horizontal plane, for example.

  In this way, by making the inclination angle of the holding means 2 variable, the holding object 5 can be held and transferred by the sideways device A, and the conveying object 5 can be conveyed smoothly and stably in the downstream portion of the conveying means 4. Can be done. That is, the inclination angle of the holding surface 18 in the initial state shown in FIG. 4A is applied from the bottom of the conveyed product 5 to the upper surface of the conveying device 4 when the conveyed product 5 is held by the holding device 2. The load to be applied is reduced, or the bottom of the conveyed product 5 is adjusted so as to be lifted from the upper surface of the conveying means 4. In this case, as shown in FIG. 3 (c), a state in which the conveyed product 5 is held by the holding means 2, and a state in which the conveyed product 5 is transferred by the transfer means 3 as shown in FIG. 4 (a). In this case, the frictional force acting between the conveyed product 5 and the conveying means 4 is reduced, or such a frictional force is prevented from acting so that the conveyed product 5 can be held and transferred smoothly and stably. can do. Further, as shown in FIG. 4B, when releasing the holding of the conveyed product 5 by the holding means 2 and the pressing means 1, the drive rod 35 of the advance / retreat drive device 39 is projected so that the inclination angle of the holding surface 18 is increased. By increasing the size, the bottom of the conveyed product 5 is brought into contact with the upper surface of the conveying means 4 and the load applied from the bottom of the conveyed product 5 to the upper surface of the conveying means 4 is increased. In this case, the driving force from the transport unit 4 is easily transmitted to the transported object 5, and the transported object 5 is transported smoothly and stably by the transport unit 4.

  The inclination angle of the holding surface 18 when changing the inclination angle of the holding means 2 as described above is appropriately set according to the size, shape, weight, density, center of gravity position, etc. of the conveyed product 5. For example, when the conveyed product 5 is a packaging bag 5a in which powder such as resin powder is packaged, the density or weight of the resin powder in the packaging bag 5a or the dimensions, shape, etc. of the packaging bag 5a The inclination angle is set as appropriate.

  Further, the holding means 2 and the pressing means 1 of the above-mentioned lying down apparatus A can be formed so as to be movable up and down together with the conveying means 4. In the example shown in FIG. 6, the conveying means 4 and the laying apparatus A are disposed on a lifter 40 that is driven up and down. If it does in this way, while adjusting the height of the conveyance means 4 according to a post process, the height of the holding means 2 and the press means 1 can be adjusted according to the height of this conveyance means 4. For example, in the case where a stacking device for sequentially taking out the transported objects 5 transported by the transporting means 4 and loading them by automatic control is provided in the subsequent process, the transporting means is adjusted in accordance with the height of the picked-up position of the transported objects 5 by the stacking device. 4 and the height of the holding means 2 and the pressing means 1 can be adjusted according to the height of the conveying means 4.

  FIG. 7 shows another embodiment. In the illustrated example, the conveyance direction of the conveyed product 5 by the conveyance means 4 is different by 90 ° between the upstream side portion including the position where the sideways device A is disposed and the downstream side portion thereof. Hereinafter, the conveying means 4 in the upstream portion is referred to as upstream conveying means 4a, and the conveying means 4 in the downstream portion is referred to as downstream conveying means 4b. The upstream end of the downstream transport unit 4b is disposed on the side of the downstream end of the upstream transport unit 4a.

  In the initial state, the laying apparatus A is arranged such that the base 10 is disposed on the side opposite to the downstream conveying means 4b at the downstream end of the upstream conveying means 4a. The base 10 is provided with the pressing means 1 and the holding means 2 in the same manner as in the embodiment shown in FIGS. 1 and 2, but is composed of the forward / backward drive device 28, the shaft body 12 and the crank 13. The means 3 is not provided, and the gantry 16 that supports the pressing means 1 and the holding means 2 is directly installed on the base 10.

  The laying apparatus A is provided with a slide moving mechanism that slides the base 10 in the horizontal direction as the transfer means 3. Thereby, the pressing means 1 and the holding means 2 are formed so as to be slidable in the horizontal direction by the transfer means 3. In the illustrated example, a guide rail 41 that is orthogonal to the transport direction of the upstream transport unit 4a and parallel to the transport direction of the downstream transport unit 4b is provided further downstream of the downstream end of the upstream transport unit 4a. The base 10 is formed to be slidable along the guide rail 41. At this time, the holding means 2 is between the state arranged on the side of the downstream end edge of the upstream conveying means 4a and the state arranged above the end on the upstream side of the downstream conveying means 4b. It is formed to slide.

  A usage pattern of the transporting apparatus A configured as described above will be described with reference to a schematic diagram shown in FIG.

  First, similarly to the case shown in FIGS. 3A to 3C, the conveyed product 5 is conveyed in the horizontal direction from the upstream side with respect to the arrangement position of the laying apparatus A in the upstream conveying means 4a such as a belt conveyor, When arranged between the holding means 2 and the pressing part 7 and detected by the photoelectric sensor 31a, the upstream conveying means 4a is stopped and the pressing means 1 is operated to move the conveyed product 5 by the pressing part 7. The carrier 5 is pressed and tilted and held on the holding surface 18 and held between the holding surface 18 of the holding means 2 and the pressing portion 7 (see FIG. 8A).

  Next, by operating the transfer means 3 to slide the base 10, the holding means 2 and the pressing means 1 are slid while holding the conveyed product 5 (see FIG. 8B). At this time, the holding means 2 is disposed behind the upstream edge of the downstream conveying means 4b, and the downward inclined direction of the holding surface 18 coincides with the conveying direction by the downstream conveying means 4b. For this reason, the conveyed product 5 is disposed in a state where the bottom portion is disposed on the downstream side of the downstream conveying means 4b, the upper portion is disposed on the upstream side, and the holding surface 18 is inclined with respect to the conveying direction when the holding surface 18 is inclined. Is done. At this time, the presence of the conveyed product 5 is detected by the photoelectric sensor 31b, and when the operation of the upstream conveying means 4a is stopped based on the detection result, the operation is resumed.

  Next, by operating the pressing means 1 so that the drive rod 22 of the advance / retreat drive device 21 is pulled, the pressing portion 7 is swung and moved away from the holding means 2 to be arranged at the original arrangement position. (See FIG. 8 (c)). As a result, the pressing portion 7 is separated from the surface of the conveyed product 5, and the holding of the conveyed product 5 by the holding means 2 and the pressing portion 7 is released. Thereby, the conveyed product 5 is conveyed downstream by the downstream conveying means 4b, and when the holding surface 18 is inclined, it moves smoothly along the inclination to the downstream side of the downstream conveying means 4b. . At this time, the conveyed product 5 is laid sideways and conveyed with the bottom portion disposed on the downstream side and the upper portion disposed on the upstream side.

  Next, the transfer means 3 is operated to return to the initial state, and the above operation is repeated, whereby the transport means 4 can be sequentially processed with respect to the transported objects 5 that are transported sequentially.
