Description

The present invention relates to a transport device for an object to be transported, which is composed of household products, foods, packaging products, chemicals and the like.

A roll body for food packaging used for preserving food and preventing drying is not shown, but a rewinding device rewinds a resin film of a predetermined length around the core, and the rewinding device changes to a cartner device. After being conveyed by the conveyor, it is inserted into the inside from the end of the packaging box raised in a square tube shape, and multiple flaps at the end of the packaging box are sequentially folded, and the folded flaps are hot-melted. The box is manufactured by being bonded (see Patent Documents 1 and 2).

The rewinding device, the conveyor, and the cartner device are installed in an orientation suitable for manufacturing the roll body as much as possible from the viewpoint of improving production efficiency. However, in consideration of the size of the installation location, it may be installed in an orientation that is not suitable for manufacturing rolls. For example, from the viewpoint of emphasizing space efficiency, they may be installed at crossing points, which may cause congestion or stagnation.

By the way, since the direction of the roll body discharged from the rewinding device deviates from the insertion direction with respect to the packaging box by 90 °, there is a problem that the roll body must be automatically rotated by 90 ° to adjust the direction during transportation by the conveyor. is there. This is because when manufacturing a roll body, a plurality of devices corresponding to the manufacturing process are required, but considering the size of the installation place of the device, etc., the roll body, which is a product, is not necessarily input to the cartner device in the subsequent process. This is because there are circumstances in which it cannot be transported from the previous process due to its orientation.

Further, the height of the conveyor surface and the height of the roll body inserted by the cartner device are not necessarily the same depending on the structure of the device, the layout of the installation location, etc., and a height difference may occur. In this case, the roll body may be different. Must be properly transferred from the height difference conveyor to the Cartner equipment.

Examples of methods for solving these problems include the adoption of an accumulator that temporarily stores the roll body, a horizontal rotary conveyor that changes the orientation of the roll body, and an industrial robot that grips and transfers the roll body.

However, when the accumulator device is adopted, there arises a problem that a new detection sensor for the roll body is required. Further, when the horizontal rotary conveyor is adopted, although the orientation of the roll body can be changed, there is a problem that new equipment is required and cost reduction cannot be achieved. In addition, if an industrial robot is introduced, automation and labor saving can be expected, but it is necessary to secure a large installation space and install a safety fence. Further, in order to secure the detection time of the roll body and the detection time of detecting the completion of the operation of the industrial robot, it is necessary to set the tact time with a margin.

The present invention has been made in view of the above, and the orientation and height of the object to be transported can be easily changed during transportation, and the detection sensor and expensive equipment are omitted to prevent work delay. It is an object of the present invention to provide an inexpensive transfer device for an object to be transported.

In the present invention, in order to solve the above problems, a first conveyor for transporting an object to be transported and a second conveyor for transporting the object to be transported protruding from the first conveyor in a direction intersecting the transport direction of the first conveyor. On one side of the second conveyor, a cushioning member that collides with the object to be transported that has jumped out of the first conveyor is provided, and on the other side of the second conveyor, the second conveyor. A device provided with a drop-out prevention member facing a dropped object to be transported.
The object to be transported is a roll body for food packaging in which a long sheet is wound around a paper core, and both ends of the core of the roll body protrude from the sheet.
In the first and second conveyors, the second conveyor is installed substantially orthogonally below the downstream front of the first conveyor, and the transport surface of the second conveyor is lower than the transport surface of the first conveyor. Has been
The first conveyor is a belt conveyor capable of transporting a plurality of rolls by circulating a plurality of belts arranged in a row by driving a drive motor. The surface of each belt is antibacterial treated and the transport speed is 100 or more and 120 m. It is set to / min or less,
The second conveyor is a belt conveyor in which the belt circulates and conveys the roll body by the rotation of the pulley based on the drive of the drive motor. The surface of the belt is antibacterial treated and the roll body is sandwiched in the longitudinal direction thereof. Guide ribs are formed at predetermined intervals, and the transport speed is set to 10 or more and 30 m / min or less.
The cushioning member is elastically deformable so as to collide with a metal plate, a felt layer laminated and bonded to the metal plate, and a core tip of a roll body laminated and bonded to the felt layer and protruding from the downstream of the first conveyor. Equipped with a urethane rubber
When the fall-off prevention member is erected on the other side of the second conveyor and faces the urethane rubber of the cushioning member, and the roll body collides with the urethane rubber of the cushioning member and falls on the belt of the second conveyor. , It is characterized in that it faces the end of the winding core of the roll body.

Here, when the object to be transported in the claims is a roll body, it is preferable that the winding core of the roll body is oriented in the transport direction of the first conveyor. The roll sheet includes a resin sheet and a resin film.

According to the present invention, the object to be conveyed is conveyed from the upstream to the downstream of the first conveyor and jumps out from the downstream of the first conveyor. The jumped object collides with a cushioning member on one side of the second conveyor, falls from this cushioning member onto the transport surface of the second conveyor, and is transported downstream of the second conveyor. At this time, the drop-off prevention member guides the dropped object to be conveyed and regulates the object to be transferred from falling from the second conveyor.

According to the present invention, there is an effect that the orientation and height of the object to be transported can be changed inexpensively and easily at the time of transportation. In addition, the detection sensor and expensive equipment can be omitted to prevent work delays. Further, since the protruding end of the winding core collides with the cushioning member instead of the sheet wound around the winding core of the roll body, contamination and damage to the sheet can be expected to be reduced. Further, since the first and second conveyors are belt conveyors, a wide range of applications from short distances to long distances is easy.

Further, the orientation of the object to be conveyed can be automatically rotated by 90 ° and adjusted during transportation by the first and second conveyors. Further, since the first conveyor is a belt conveyor that circulates a plurality of belts arranged in a row to convey a plurality of rolls, even if a plurality of rolls are conveyed at the same time, they are only dropped from the first conveyor. , A large amount of processing can be performed at one time without retaining a plurality of rolls. Further, since the transport speed of the first conveyor is 100 or more and 120 m / min or less, the jumping distance of the roll body from the first conveyor is sufficient, and the roll body collides with the transport surface of the second conveyor and is damaged. It becomes possible to suppress. In addition, it becomes possible to prevent the roll body from popping out more vigorously than necessary and causing the roll body to strongly collide with the cushioning member and be damaged.

Further, since the transport speed of the second conveyor is 10 or more and 30 m / min or less, it is possible to eliminate the possibility that the roll body is displaced from the plurality of guide ribs and the roll body cannot be expected to be properly transported. Further, when the roll body collides with the urethane rubber of the cushioning member, the urethane rubber is deformed to alleviate the impact between the roll body and the cushioning member, so that it is possible to prevent the roll body from being damaged due to the collision.

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings. As shown in FIGS. 1 to 4, the conveyor for the object to be transported in the present embodiment conveys the roll body 1 for food packaging. A second belt conveyor 10 is provided with a first belt conveyor 10 and a second belt conveyor 20 that conveys the roll body 1 protruding from the first belt conveyor 10 in a direction intersecting the conveying direction of the first belt conveyor 10. A cushioning plate 30 that collides with the protruding roll body 1 is erected on one side of the belt conveyor 20, and the roll body 1 that has fallen onto the second belt conveyor 20 is placed on the other side of the second belt conveyor 20. The fall-out prevention plate 40 facing the wall is erected.

As shown in FIGS. 1 to 3, the roll body 1 for food packaging includes a winding core 2, and a transparent band-shaped film 4 is formed on the outer peripheral surface of the winding core 2 upstream of the first belt conveyor (FIG. 2). It is wound about 20 m or more and about 50 m, or about 50 m or more and 110 m by the rewinding device (to the left), and can be rotated into the packaging box by the cartner device downstream of the second belt conveyor (downward in FIG. 2). It is stored.

The winding core 2 is formed in a cylindrical shape by a predetermined paper, and both end portions 3 project from the wound film 4. Further, the film 4 is formed into a flexible thin film by, for example, polyvinylidene chloride, polyvinyl chloride, polyethylene, etc., which are excellent in heat resistance, water resistance, etc., and is drawn out from the roll body 1 by a predetermined length, and then the packaging box is formed. It is cut by a cutting blade and used for food packaging.

As shown in FIGS. 1 and 2, the first and second belt conveyors 10 and 20 are installed so that the upstream of the second belt conveyor 20 is orthogonal to the lower side of the downstream front of the first belt conveyor 10. The first belt conveyor 10 located at a higher position and the second belt conveyor 20 located at a lower position are combined in a flat L shape, and the roll body 1 protrudes from the outbound belt surface downstream of the first belt conveyor. The roll body 1 falls on the lower belt outward path surface upstream of the second belt conveyor and is conveyed. The height difference from the belt outward path surface of the first belt conveyor 10 to the belt outward path surface of the second belt conveyor 20 is not particularly limited, but is, for example, 1 m or less, 70 cm or less, 50 cm or less, and the like.

The first belt conveyor 10 includes a plurality of pulleys rotatably supported at both ends of the gantry 11, and a plurality of belts 12 that are tensioned and wound between the plurality of pulleys. This is a high-speed belt conveyor in which a plurality of belts 12 circulate at high speed to convey the roll body 1 by rotating a pulley based on the drive of a drive motor of the gantry 11. The gantry 11 of the first belt conveyor 10 is configured to be flat, at least partially inclined, or curved, if necessary.

Examples of the drive motor of the first belt conveyor 10 include a brushless motor, an induction motor, and a gad motor. Further, in the plurality of belts 12, for example, 5 or more and 10 or less thin belts 12 are arranged in a horizontal row so that a plurality of roll bodies 1 can be conveyed at the same time, and each belt 12 is SBR rubber, EPR rubber, silicone. It is a flat belt made of rubber, polyurethane, polyester, nylon, etc., and each belt 12 circulates at high speed, and the tip of the roll body 1 which is the end 3 of the winding core 2 is in the downstream direction, in other words, Transport so that it faces the transport direction. The surface of the belt 12 in contact with the roll body 1 is subjected to antibacterial treatment, antifungal treatment, etc. with urethane, fluororesin, or the like so as to comply with the Food Sanitation Law.

The transport speed of the first belt conveyor 10 is 100 or more and 120 m / min or less, preferably 102 or more and 110 m / min or less, and more preferably 105 or more and 108 m / min or less. This is because when the transport speed is less than 100 m / min, the protrusion distance of the roll body 1 becomes insufficient, and the film 4 of the roll body 1 collides with the transport surface of the second belt conveyor 20 and is damaged. is there. On the contrary, when it exceeds 120 m / min, the roll body 1 pops out more vigorously than necessary, and the tip of the winding core of the roll body 1 strongly collides with the cushioning plate 30 and is crushed.

The second belt conveyor 20 includes a plurality of pulleys rotatably supported at both ends of the gantry 21, and an endless belt 22 that is tensioned and wound between the plurality of pulleys. This is a low-speed belt conveyor in which the belt 22 circulates at a low speed to convey the roll body 1 by the rotation of the pulley based on the drive of the drive motor of 21. The gantry 21 of the second belt conveyor 20 is configured to be flat, at least partially inclined, or curved, if necessary.

The type of the drive motor of the second belt conveyor 20 and the material of the belt 22 are not particularly limited, and are the same as those of the first belt conveyor 10, for example. The belt 22 is formed wider than the belt 12 of the first belt conveyor 10, and a plurality of guide ribs 23 that sandwich the roll body 1 in the longitudinal direction of the surface are integrally formed at predetermined intervals, and a plurality of these guide ribs 23 are integrally formed with the surface. The guide rib 23 is subjected to antibacterial treatment, antifungal treatment, etc. with urethane, fluororesin, or the like so as to comply with the Food Sanitation Law. As shown in FIG. 2, the transport direction of the belt 22 is orthogonal to the direction of the winding core 2 of the roll body 1.

The transport speed of the second belt conveyor 20 is not particularly limited, but is 10 or more and 30 m / min or less, preferably 11 or more and 20 m / min or less, and more preferably 12 or more and 15 m / min or less. This is because if it deviates from the range of 10 or more and 30 m / min or less, the roll body 1 may be displaced from between the plurality of guide ribs 23, and proper transportation of the roll body 1 may not be expected.

As shown in FIGS. 1, 2 and 4, the cushioning plate 30 is formed on a horizontally long metal plate 31 made of, for example, SUS or the like, a thin felt layer 32 laminated and adhered to the metal plate 31, and the felt layer 32. The elastic elastomer layer 33 to be laminated and bonded is provided in a multi-layer structure, and is erected horizontally on one side of the pedestal 21 of the second belt conveyor 20 in the transport direction via a fastener.

The elastic elastomer layer 33 is not particularly limited, and examples thereof include elastically deformable urethane rubber, nitrile rubber, silicone rubber, chloroprene rubber, and butyl rubber, which collide with the tip of the core of the roll body 1. Such a buffer plate 30 collides with the tip end portion of the roll body 1 protruding from the downstream side of the first belt conveyor 10 and functions to drop the roll body 1 onto the belt outward path surface of the second belt conveyor 20. ..

As shown in FIGS. 1 and 2, the fall-off prevention plate 40 is made of a horizontally long metal plate made of, for example, SUS or the like, and stands on the other side of the gantry 21 of the second belt conveyor 20 in the transport direction via a fastener. It is provided and faces the elastic elastomer layer 33 of the cushioning plate 30 via the belt 22. The fall-off prevention plate 40 faces the end portion 3 of the roll body 1 that collides with the elastic elastomer layer 33 of the cushioning plate 30 and falls on the belt outward path surface of the second belt conveyor 20, and the roll body 1 Functions to prevent the second belt conveyor 20 from falling off due to the reaction in the event of a collision.

In the above configuration, when the roll body 1 is conveyed from the upstream rewinding device to the downstream cartner device, the roll body 1 is conveyed from the upstream to the downstream of the first belt conveyor 10 at high speed by the circulation of the belt 12. The tip of the winding core 2 protrudes forward from the downstream side of one belt conveyor 10.

Then, the roll body 1 falls while drawing a parabolic line, and the tip portion collides with the elastic elastomer layer 33 of the cushioning plate 30 standing upstream on one side of the second belt conveyor 20, and the second one from the cushioning plate 30. It falls on the belt outward path surface of the belt conveyor 20 and is sandwiched between the plurality of guide ribs 23, and is conveyed by the circulation of the belt 22 from the upstream to the downstream of the second belt conveyor 20 and is conveyed to the cartner device downstream. Become. At this time, the drop-off prevention plate 40 guides the roll body 1 in the transport direction facing the end portion of the roll body 1 and effectively prevents the roll body 1 from falling off from the second belt conveyor 20 sideways.

According to the above configuration, since the first and second belt conveyors 10 and 20 are orthogonal to each other from the viewpoint of emphasizing space efficiency, the orientation of the roll body 1 is automatically switched and adjusted by 90 ° during transportation by the belt conveyor. Can be done. Further, since the roll body 1 jumps out from the downstream of the first belt conveyor 10 and falls to the second belt conveyor 20 and is conveyed, there is a height difference between the first and second belt conveyors 10 and 20. However, the roll body 1 can be appropriately transferred from the second belt conveyor 20 to the cartner device. Further, even if a large number of roll bodies 1 are conveyed at the same time, they are only dropped from the first belt conveyor 10, so that the roll bodies 1 can be mass-processed at one time without staying.

Further, since it is not necessary to particularly adopt an expensive accumulator device, a detection sensor for the roll body 1 is not required. Further, since it can be handled only by the first and second belt conveyors 10 and 20, the cushioning plate 30, and the dropout prevention plate 40, maintenance and adjustment are really easy. Moreover, since it is not necessary to adopt a horizontal rotary conveyor in particular, there is no need to introduce any new equipment, and cost reduction can be greatly expected. Moreover, since it is not necessary to introduce an expensive industrial robot, it is not necessary to secure a large installation space. Further, since it is not necessary to secure the detection time of the roll body 1 and the detection time for detecting the completion of the operation of the industrial robot, it is not necessary to set the tact time with a margin.

In the above embodiment, the first belt conveyor 10 and the second belt conveyor 20 are combined in a flat L shape, but they may be combined in a flat T shape or the like. Further, the plurality of first belt conveyors 10 and the second belt conveyor 20 may be combined in a flat E-shape, an F-shape, or the like. Further, a rewinding device is installed upstream of the first belt conveyor 10 and a cartner device is installed downstream of the second belt conveyor 20, but the present invention is not limited thereto. For example, various supply devices and other conveyors may be installed upstream of the first belt conveyor 10, and inspection devices and the like may be installed downstream of the second belt conveyor 20. Further, the first and second belt conveyors 10 and 20 may be installed by crossing them at angles such as 70 °, 80 ° and 100 °.

Further, the buffer plate 30 may be erected on one side upstream of the second belt conveyor 20, but it can be erected on one side extending from the upstream to the downstream. Further, although the buffer plate 30 is formed in a multilayer structure of a metal plate 31, a felt layer 32, and an elastic elastomer layer 33, it is formed in a multilayer structure of a metal plate 31 and an elastic elastomer layer 33, or is formed only by an elastic elastomer. be able to. Further, the cushioning plate 30 may be upright or may be upright while being tilted.

Further, the fall-off prevention plate 40 may be erected on the other side upstream of the second belt conveyor 20, but it may also be erected on the other side extending from the upstream to the downstream. Further, the fall-off prevention plate 40 can be formed in a multilayer structure of a metal plate 31 and an elastic elastomer layer 33, or can be formed by an elastic elastomer. Further, it is also possible to use a horizontally long rod made of elastic elastomer that extends in the transport direction instead of a plate for preventing falling off.

The transport device for a transported object according to the present invention is used in a field of manufacturing or transporting a transported product including household products, building supplies, food, packaging products, chemicals and the like.
