Description

The present invention relates to a bread transfer system for transferring bread such as bread and sweet bread, and more particularly to a bread transfer system for storing bread in a bag for transporting.

When bread such as bread and sweet bread is manufactured, the bread is packed in a packaging material such as polyethylene in the packaging process, and then the packed bread is stored in a transport container with an open top in the casing process. Will be done.

Generally, the internal dimensions of the transport container are sized to accommodate a predetermined number of packaging pans. The packaging pan is manually stored in a substantially rectangular transport container in a plan view (see Patent Document 1).

Further, in order to improve the work efficiency of the casing process, it is conceivable to transfer the packaging pan to the transport container by using a transport means such as a belt conveyor. When the transport means is used, the packaging pan is stored in the transport container by using the belt conveyor, which is the transport means, with respect to the transport container placed at a place lower than the place where the packaging pan is placed. To. Further, since the endless belts constituting the belt conveyor are arranged so as to be inclined, for example, four breads to be transferred are arranged in the transport direction and three breads are arranged in the direction orthogonal to the transport direction. In the case of a bread group arranged in 4 rows and 3 columns, the breads arranged on the downstream side constituting the bread group are stored in the transport container in order from the bread group.

Japanese Patent Application Laid-Open No. 08-023868

According to the bread transfer method using the above-mentioned transport means, the breads on the downstream side along the transport direction, that is, the breads constituting the first to third rows of the bread group, are relatively smoothly stored in the transport container. Will be done. On the other hand, in the bread that constitutes the fourth row of the bread group, the downstream end of the endless belt on the downstream side in the transport direction enters the transport container, which hinders the movement of the bread and stores the bread. When moving the transport container, it is necessary to move the downstream end of the endless belt upward in the vertical direction to separate it from the transport container. Therefore, the operation of the endless belt causes the bread to be flipped up to a predetermined position in the transport container. There is a risk that bread will not be placed in.

Further, when the breads constituting the first to third rows of the bread group are not arranged at predetermined positions in the transport container, the breads constituting the first to third rows are added to the fourth row. There is a risk that the breads that make up the bread will collide with each other and the breads will be deformed, or that the breads will not be placed in place. In order to prevent such a problem, it is possible to prevent the inner dimension of the storage container in which the bread is stored by sizing it relatively larger than the outer dimension of the arranged bread group.

However, in the future, it is expected that smaller transport containers, lower transport costs, and smaller manufacturing plant spaces will be required, and the current transfer system may not be able to meet these demands.

On the other hand, the other tension pulley 54 and the drive pulley 55 constituting the rolling member are rotatably supported by a support shaft (not shown), and the support shaft is fixedly mounted on the housing 100. Therefore, the moving pulley 53 and the reciprocating pulley 52 can move with respect to the tension pulley 54 and the driving pulley 55 so as to move away from or closer to each other in the transport direction D.

Next, the elevating shutter portion (that is, the elevating / closing means) 15 will be described with reference to FIGS. 2 (a) and 2 (b). The elevating shutter portion 15 of the present embodiment is arranged on the downstream side of the belt conveyor 5 in the transport direction D, and the bread group B transported by the belt conveyor 5 is transferred to the transport container C.

The elevating shutter unit 15 includes a shutter unit 90 that opens and closes in a direction orthogonal to the transport direction D (horizontal directions of FIGS. 2A and 2B) and a shutter opening / closing driving means 91 for opening / closing the shutter unit 90. Be prepared. The shutter portion 90 is composed of a pair of plate-shaped members 92 having a symmetrical shape, each of the pair of plate-shaped members 92 is connected to a shutter opening / closing driving means 91, and the opening / closing driving means is, for example, an air cylinder. It is configured. Further, the shutter opening / closing driving means 91 is connected to the control unit 7 and can be controlled in synchronization with other components constituting the bread transfer system 1. Further, the upper surface 92a on which the plate-shaped member 92 and the bread group B are placed extends in the horizontal direction.

Further, the elevating shutter unit 15 is connected to the shutter elevating drive unit 93 so that the elevating shutter unit 15 can be elevated in the vertical direction shown in FIGS. 1A, 2A, and 2B.

In the above configuration, the pair of plate-shaped members 92 are moved up and down by the shutter elevating drive unit 93 in the vertical direction of FIGS. 1 (b), 2 (a), and (b) by the drive signal from the control unit 7. The shutter opening / closing driving means 91 can perform opening / closing movements in the left-right directions of FIGS. 2A and 2B.

As shown in FIG. 1A, the pusher mechanism 9 includes a pressing plate for urging the downstream end side of the bread group B, that is, a pressing movable guide 31, a pressing movable guide 31, and a pressing driving unit (not shown). It is provided with a pressing connecting portion 32 for connecting the above. As shown in FIG. 1A, the pressing movable guide 31 is movable between the standby position S1 indicated by the alternate long and short dash line and the pressing position S2 indicated by the solid line. When the endless belt 50 extends (shown by the solid line in FIG. 1A) and reaches the most downstream position L2 of the endless belt 50, the pressing movable guide 31 descends downward in FIG. 5B. , Moves downstream along the transport direction D and reaches the pressing position S2. The length dimension of the transport direction D between the product fixing guide (downstream side guide) 61 and the pressing movable guide (pressing means) 31 in this state is slightly shorter than the inner dimension of the transport direction D of the transport container C. ..

The bread group B is arranged in a predetermined arrangement form when it is placed on the mounting surface 50a of the endless belt 50 on the upstream side. However, it is conceivable that the length dimension of the bread group B with respect to the transport direction D does not match the length dimension of the transport direction D of the transport container C. Therefore, when the bread group B is pressed by the pressing movable guide 31, the length dimension of the predetermined arrangement form with respect to the transport direction D is dimensioned so as to be slightly smaller than the internal dimension of the transport container C with respect to the transport direction D. can do. Further, in a state where the endless belt 50 extends to the most downstream position L2, the region of the mounting surface 50a between the product fixing guide 61 and the pressing movable guide 31 extends horizontally, and the product fixing guide 61 and the pressing movable guide 31 extend horizontally. 31 extends in the vertical direction. The product fixing guide 61 is attached to the housing 200.

Further, a pair of widthwise movable guides 65 and 67 arranged to face each other in the width direction orthogonal to the transporting direction D of the endless belt 50 are mounted on the housing 200. The widthwise movable guides 65 and 67 are movably connected to a driving means (for example, an air cylinder) (not shown) so as to be movable in a direction away from each other and in a direction approaching each other. The bread group B transported by the endless belt 50 has the width direction dimension of the bread group B (direction orthogonal to the transport direction D) slightly smaller than the inner dimension of the transport container C by the above-mentioned width direction movable guide. Adjusted to the dimensions. Further, the regions of the width direction movable guides 65 and 67 that come into contact with the bread group B extend in the vertical direction.

Further, in the present embodiment, as described above, the bread group B exhibits a predetermined arrangement form when placed on the endless belt 50, but is sized so as to conform to the internal dimensions of the transport container C. Not. Therefore, the bread group B is dimensioned in the transport direction D by the pressing movable guide 31 and the product fixing guide 61, and is dimensioned in the width direction by the pair of width direction movable guides 65 and 67.

The pair of plate-shaped members 92 of the elevating shutter portion 15 described above are configured to be positioned at the uppermost position H1, the intermediate position H2, and the lowest position H3. When the pair of plate-shaped members 92 are arranged at the uppermost position H1, the bread group B constituting the first stage is placed, and when they are arranged at the intermediate position H2, the second stage is formed. When the bread group B to be used is placed and placed at the lowest position H3, the bread group B is transferred to the discharge conveyor 13. In a state where the pair of plate-shaped members 92 is lowered to the lowest position H3, the pair of plate-shaped members 92 are positioned directly above the transport container C arranged on the discharge conveyor 13 described later.

Further, below the elevating shutter portion 15 (downward in the vertical direction in FIG. 1A), a discharge conveyor 13 for transporting the transport container C in which the bread group B is stored is arranged. The discharge conveyor 13 is a means for transporting the transport container C to which the bread group B is transferred to the next process by the elevating shutter unit 15. As shown in FIG. 1A, a discharge endless belt 74 having a mounting surface extending in a substantially horizontal direction, and a known drive pulley (not shown) and a driven pulley 75 around which the discharge endless belt 74 is wound. And an electric motor 98, which is a known drive means for rotating the drive pulley. In the discharge conveyor 13 having the above configuration, when the bread group B is transferred to the transport container C, the electric motor 98 is driven so that the discharge endless belt 74 moves the transport container C downstream along the transport direction D. Transport.

Next, the process of transferring the bread group B to the transport container C using the bread transfer system 1 will be described with reference to FIGS. 5 (a) to 5 (f). As described above, FIGS. 5 (a) to 5 (f) schematically show a step of transferring the bread group B formed by arranging the packed bread b in 4 rows and 3 columns. It is a figure.

In FIG. 5A, the first-stage bread group B housed in the transport container C is located near the most downstream position L2 of the endless belt 50, and the second-stage bread group B is the endless belt. It shows the state of being located on the upstream side of 50. At this time, the plate-shaped member 92 of the elevating shutter portion 15 is located at the highest position in the vertical direction of FIG. 5 (a) (see reference numeral H1 of FIG. 1 (a)). The upper surface 92a of the plate-shaped member 92 is located in the vicinity of the return surface (the surface facing downward in the vertical direction in the region of the endless belt 50 advancing in the counter-conveying direction d) 50b of the endless belt 50. Further, the most downstream end of the bread group B is supported by the product fixing guide 61. Therefore, since the endless belt 50 rotates in the transport direction D, a urging force is applied to the bread group B on the downstream side, but the endless belt 50 is locked by the product fixing guide 61.

Further, the pressing movable guide 31 moves in the direction approaching the product fixing guide 61, presses the most upstream end of the bread group B, and the length direction dimension of the bread group B with respect to the transport direction D is the transport of the transport container C. The dimensioning is performed so as to be slightly smaller than the length dimension in the direction D. Further, the positions where the movable guides 65 and 67 in the width direction (see FIGS. 1A and 2) are separated from each other (two-dot chain line in FIG. 1B) and approach each other (in the solid line in FIG. 1B). (Shown) moves in a direction orthogonal to the transport direction D (states shown in FIGS. 2A and 2B), and the width direction dimension of the product pan group B is orthogonal to the transport direction D of the transport container C. Adjusted slightly shorter than the (width direction) dimensions.

In the present embodiment, the bread group B constituting the first stage and the bread group B constituting the second stage are shown separated by a predetermined distance in the transport direction D, but are to be transferred. Needless to say, the number and spacing of the objects to be transferred are appropriately changed depending on the length of the object, the transport speed of the endless belt 50, and the like.

Next, as shown in FIG. 5B, the moving pulley 53 and the reciprocating pulley 52 that support the downstream end of the endless belt 50 move in the counter-conveying direction d, so that the endless belt 50 moves to the most upstream position L1. Move to. At this time, the position of the pressing movable guide 31 is maintained at the pressing position shown in FIG. 5A. Therefore, in the bread group B, the product fixing guide 61, the pressing movable guide 31, and the width direction movable guides 65 and 67 are also shown in FIG. The bread group B is placed (falls) on the upper surface 92a of the plate-shaped member 92 in the state of being dimensioned according to (a). That is, the bread group B is transferred to the plate-shaped member 92 while maintaining a predetermined arrangement form.

Further, as shown in FIG. 5C, the plate-shaped member 92 of the elevating shutter portion 15 descends from the uppermost position H1 to the intermediate position H2. At this time, the first-stage bread group B mounted on the plate-shaped member 92 has an upstream side fixing guide (upstream side guide) 63, a product fixing guide 61, and a width direction instead of the pressing movable guide 31. It is supported by movable guides 65 and 67. In this way, it is possible to prevent the force in the direction in which the bread b is tilted from acting on each bread b constituting the bread group B, so that the arrangement form of the bread group B is not disturbed and is endless. It is transferred from the belt 50 to the elevating shutter unit 15.

In the process shown in FIG. 5D, the moving pulley 53 and the reciprocating pulley 52 move to the upstream side, and the endless belt 50 reaches the most upstream position L1. As the moving pulley 53 and the reciprocating pulley 52 regress in the counter-conveying direction d in this way, the bread group B constituting the second stage falls onto the bread group B of the first stage.

As described above, FIG. 5D shows that the return surface 50b of the endless belt 50 and the upper surface of the bread group B placed on the plate-shaped member 92 are in a positional relationship close to each other to the extent that they do not come into contact with each other. The fall distance of the bread group B when reaching the state is minimized.

The bread group B in the second stage is supported by the width direction movable guides 65 and 67 in the width direction, and by the product fixing guide 61 and the pressing movable guide 31 in the transport direction D. Further, similarly to the state shown in FIG. 5B, the bread group B in contact with the pressing movable guide 31, the product fixing guide 61, and the width direction movable guides 65 and 67 is adjusted to have a predetermined size. That is, they are arranged in the same state as the bread group B placed on the upper surface 92a of the plate-shaped member 92.

Further, as shown in FIG. 5 (e), the plate-shaped member 92 descends to the lowest position H3. At this time, the two-tiered bread group B is supported by the width direction movable guides 65 and 67 in the width direction, and by the product fixing guide 61 and the upstream side fixing guide 63 in the transport direction D, and is arranged in a predetermined arrangement form. The pressing movable guide 31 returns to the standby position S1.

Finally, as shown in FIG. 5 (f), the plate-shaped member 92 is opened at the lowest position H3 directly above the transport container C ( see FIG. 2 (b )), and the first stage and the first stage and the first stage are opened. The second-stage bread group B falls together while maintaining a predetermined arrangement form. The product fixing guide 61, the upstream side fixing guide 63, and the width direction movable guides 65 and 67 regulate the movement in the horizontal direction. Therefore, the bread group B stacked in two stages falls while maintaining its arrangement form. Therefore, the bread groups B stacked in two stages are stored in the transport container C without being hindered by the wall portion W of the transport container C. As described above, the step of transferring the bread b by the bread transfer system 1 is performed, and the step of storing the bread b in another transport container C repeats the steps of FIGS. 5 (a) to 5 (f) described above. Is done by.

As shown in FIG. 5 (f), when a predetermined number of breads are stored in the transport container C, the transport container C is transported to the next step by the discharge conveyor 13.

The pair of plate-shaped members 92 of the present embodiment are configured to move in the width direction to open and close, but can also be configured to move in the transport direction D to open and close. Further, in the present embodiment, a predetermined gap is provided between the pair of plate-shaped members 92 in the closed state in the width direction, but the size and presence / absence of this gap depends on the object to be transferred. Can be changed as appropriate. Further, in the closed state of the pair of plate-shaped members 92, the tip portions adjacent to each other extend in parallel with the transport direction D, but extend at a predetermined angle with respect to the transport direction D. It is also possible to make the tip part of the shape to be shaped.

It includes a swing shaft 174 to which the other end of the portion 172 is swingably connected, and an air cylinder 173 which is a swing drive unit connected substantially in the middle in the longitudinal direction of the lever portion 172. The lever portion 172 swings in the left-right direction in FIG. 6A by an air cylinder 173 around a swing shaft 174 fixed to the other end portion. The swing shaft 174 extends in the depth direction of FIG. 6A. Further, the air cylinder 173 is electrically connected to the control unit 7, and is controlled by the control unit 7 in the same manner as the other components of the bread transfer system 301, as will be described later.

In the above configuration, the guide plate 163 and the lever portion 172 have an upright position indicated by a two-dot chain line extending in the vertical direction and an open position indicated by a solid line inclined upstream with respect to the vertical direction. It can swing between. The guide plate 163 in the upright position and the product fixing guide 61 are arranged so that the length dimension with respect to the transport direction D is slightly smaller than the inner dimension of the transport container C with respect to the transport direction D. Further, the length dimension of the guide plate 163 in the lateral direction (the vertical dimension of FIG. 6B) is the height (length in the vertical direction) of the bread group B stacked in two stages in the present embodiment. ) The size is slightly larger than the size, and the guide plate 163 can come into contact with the uppermost stream side end of the two-stage bread B. Therefore, when the lever portion 172 is swung from the open state to the upright state, the guide plate 163 is engaged with the bread group B stacked in two stages, and the arrangement form of the bread group B can be adjusted.

Hereinafter, the process of transferring the bread group B to the transport container C using the bread transfer system 301 according to the second embodiment will be described with reference to FIGS. 7 (a) to 7 (f). As described above, FIGS. 7 (a) to 7 (f) schematically show a step of transferring the bread group B formed by arranging the packed bread b in 4 rows and 3 columns. It is a figure.

In FIG. 7A, the first-stage bread group B housed in the transport container C is located near the most downstream position L2 of the endless belt 50, and the second-stage bread group B is the endless belt. It shows the state of being located on the upstream side of 50. At this time, the upstream guide 162 is in the open position (the position shown by the solid line in FIG. 6A). The upper surface 92a of the plate-shaped member 92 is located in the vicinity of the return surface (the surface facing downward in the vertical direction when the endless belt 50 advances in the counter-conveying direction d) 50b of the endless belt 50. Further, the most downstream end of the bread group B is supported by the product fixing guide 61. Since the endless belt 50 rotates in the transport direction D, a urging force is applied to the bread group B on the downstream side, but the bread group B is locked by the product fixing guide 61.

Further, unlike the first embodiment, the bread transfer system 301 of the present embodiment does not have a pressing movable guide (see reference numeral 31 in FIG. 1A), so that the bread group B is arranged at this stage. Is not adjusted. On the other hand, the positions where the movable guides 65 and 67 in the width direction (see FIGS. 1A and 2) are separated from each other (two-dot chain line in FIG. 1B) and approach each other (in the solid line in FIG. 1B). (Shown) moves in a direction orthogonal to the transport direction D (states shown in FIGS. 2A and 2B), and the width direction dimension of the product pan group B is orthogonal to the transport direction D of the transport container C. Adjusted slightly shorter than the (width direction) dimensions.

Next, as shown in FIG. 7B, the moving pulley 53 and the reciprocating pulley 52 that support the downstream end of the endless belt 50 move in the counter-conveying direction d, so that the endless belt 50 moves to the most upstream position L1. Move to. At this time, since the endless belt 50 is rotated so as to apply an urging force to the product fixing guide 61 side with respect to the bread group B, the bread group 50 itself moves in the counter-conveying direction d. The urging force in the counter-conveying direction d with respect to B is offset, and the bread group B is placed (falls) on the upper surface 92a of the plate-shaped member 92.

Further, as shown in FIG. 7C, the plate-shaped member 92 of the elevating shutter portion 15 descends from the uppermost position H1 to the intermediate position H2. At this time, the first-stage bread group B mounted on the plate-shaped member 92 is supported by the widthwise movable guides 65 and 67. Similar to the first embodiment, it is possible to prevent the arrangement form from being disturbed in the width direction of the bread group B. However, the arrangement form of the bread group B with respect to the transport direction D is not always sized to a predetermined size because the upstream movable guide 160 is open.

In the process shown in FIG. 7D, the moving pulley 53 and the reciprocating pulley 52 move to the upstream side, and the endless belt 50 reaches the most upstream position L1. As described above, the moving pulley 53 and the reciprocal pulley 52 regress in the counter-conveying direction d to form the second stage as described with respect to the bread group B constituting the first stage in FIG. 7B. The bread group B to be used falls and is placed on the bread group B in the first stage.

As described above, FIG. 7D shows that the return surface 50b of the endless belt 50 and the upper surface of the bread group B placed on the plate-shaped member 92 are in a positional relationship close to each other to the extent that they do not come into contact with each other. The fall distance of the bread group B when reaching the state is minimized.

The bread group B in the second stage is supported by the width direction movable guides 65 and 67 in the width direction. In this way, the second-stage bread group B is arranged in the same state as the first-stage bread group B placed on the upper surface 92a of the plate-shaped member 92.

Further, as shown in FIG. 7 (e), the plate-shaped member 92 descends to the lowest position H3. Then, the guide plate 163 swings from the open position to the upright position. At this time, the two-tiered bread group B is supported by the width direction movable guides 65 and 67 in the width direction and by the product fixing guide 61 and the guide plate 163 in the transport direction D, and is arranged in a predetermined arrangement form. As described above, in the bread transfer system 301 of the second embodiment, the length dimension of the arrangement form in the transport direction D in the state where both the bread groups B to be stacked in two stages are placed on the plate-shaped member 92. Is adjusted. In the second embodiment, the upstream movable guide 160 is provided instead of the pressing movable guide 31 and the upstream fixed guide 63 provided in the bread transfer system 1 of the first embodiment. Therefore, the configuration of the second embodiment can be simplified as compared with the configuration of the first embodiment.

Finally, as shown in FIG. 7 (f), the plate-shaped member 92 located at the lowest position H3 directly above the transport container C is opened (see FIG. 2 (d)), and the first stage and the first stage and The bread group B in the second stage falls together while maintaining a predetermined arrangement form. The product fixing guide 61, the guide plate 163, and the width direction movable guides 65 and 67 regulate the movement in the horizontal direction. Therefore, the bread group B stacked in two stages falls while maintaining its arrangement form. The bread groups B stacked in two stages are stored in the transport container C without being hindered by the wall portion W of the transport container C. As described above, the step of transferring the bread b by the bread transfer system 301 is performed, and the step of storing the bread b in another transport container C repeats the steps of FIGS. 7 (a) to 7 (f) described above. Is done by.

In the first and second embodiments, the endless belt 50 is configured to rotate at a constant speed, but the endless belt may be configured to rotate intermittently or irregularly. Further, in the second embodiment, the bread group B is configured to fall on the upper surface 92a of the plate-shaped member 92 in a state where the bread group B is locked by the product fixing guide 61, but the bread group B is the product. The endless belt 50 may move in the counter-conveying direction d before coming into contact with the fixed guide 61, and the bread may fall.

The pair of plate-shaped members 92 of the first and second embodiments are configured to move in the width direction to open and close, but are configured to move in the transport direction D or in a direction intersecting the transport direction D to open and close. It is also possible. Further, in the present embodiment, a predetermined gap is provided between the pair of plate-shaped members 92 in the closed state in the width direction, but the size and presence / absence of this gap depends on the object to be transferred. Can be changed as appropriate.
