Description

  The present invention relates to an article group binding system.

  For example, various articles packed in a cardboard box or the like are stored in or taken out of a factory or a distribution warehouse in a state of being accumulated together with other articles of the same kind similarly packed. The group of articles thus accumulated is loaded on a resin or wooden cargo table called a pallet, and then transported to a predetermined place by transport means such as a tractor.

  In order to prevent collapse of the load during transportation, a bundle process is performed on the group of accumulated articles to bind them. Examples of the binding process include stretch film packaging (bundling) in which a long strip-shaped resin film is wound around the entire side surface of the article group, and horizontal binding in which a resin string is wound around the side surface of the article group and wound (tied). And the like.

  Techniques related to such a binding process are disclosed in Patent Literature 1 and Patent Literature 2 below. In the technique disclosed in Patent Document 1, a film dispenser having a pre-stretch portion is provided on a rotating ring provided to be vertically movable with respect to a frame, and the rotating ring is lowered from the upper side of the load to load the film. The present invention relates to a stretch packaging device (bundling device) that is wound around the entire side surface.

  The technique disclosed in Patent Document 2 relates to a stretch film unwinding device, and an automatic stretch wrapping machine (bundling machine) that relatively rotates the unwinding device and the packaged object and winds the film around the packaged object. .

JP 2008-535743 A Japanese Utility Model Registration No. 3013715

  All of the techniques disclosed in the above-mentioned patent documents use a belt conveyor for conveying a group of articles to be bound to a binding device (see, for example, FIGS. 2 and 3 of Patent Document 1 and Patent Document 2). (See FIG. 2). With reference to FIG. 6, an outline of a conventional article group binding system 60 using a belt conveyor will be described.

  As shown in FIG. 6, the article group PG placed on the belt conveyor 690 is transported to a predetermined position in the binding device 630 (in the case of the embodiment in FIG. Nearly center position). When the article group PG is transported to a predetermined position in the binding device 630, the movement of the article group PG is stopped. Thereafter, the binding operation of the binding device 630 is started, and the binding body 631 (for example, a stretch film) is wound around the article group PG. Thereby, the article group PG is bound. After the binding process, the article group PG further moves on the belt conveyor 690, and is finally conveyed to, for example, a waiting place of a tractor that transports the bound article group PG.

  However, according to the method in which the group of articles is transported by the belt conveyor as described above, the installation location of the binding device needs to correspond to the laying position of the belt conveyor. For this reason, in a facility such as a factory or a distribution warehouse, a large restriction is imposed on the installation layout and the number of the binding devices. As a result, various inconveniences such as a reduction in the efficiency of various operations (conveyance and bundling processing, etc.) on the article group or a difficulty in increasing the number of bundling processing per unit time of the unbound article group are made difficult. Can occur. In many cases, a belt conveyor is individually provided according to the type of the article group (in other words, separate belt conveyors are provided for transporting one article group of different types and another article group, respectively). In this case, the same number of binding devices as the number of belt conveyors must be provided.

  In view of the above-mentioned problems, the present invention improves a series of work efficiency including a bundling process, which is performed on a group of articles housed in a predetermined facility without restricting an installation layout of a bundling device. The purpose is to provide a group unity system. It is another object of the present invention to provide an article group binding system that increases the number of binding processes per unit time of an article group accommodated in a predetermined facility without restricting the number of binding apparatuses installed. It is another object of the present invention to provide an article group binding system capable of minimizing the number of binding devices and reducing the cost of equipment construction.

To solve the above problems,
The article group binding system according to the present invention,
An article group binding system that binds the article group in order to prevent the collapse of the article group in which a plurality of articles are accumulated,
An unmanned transport device that transports the unbound state of the article group to a predetermined position,
An article group detection unit that detects that the article group has been transported to a predetermined position by the unmanned transport apparatus,
After the article group is detected by the article group detection means, a binding device for binding the article group,
Is provided.

  Here, as the “article”, for example, a unit (a drink-filled individual bottle, a processed food, etc.) in which contents (food and drink, daily miscellaneous goods, etc.) are enclosed in a bottle, can, bag, or the like. Or a unit package in which a plurality of the unit products are sorted by type and packed in one container (such as a cardboard box). . In addition, the “article group” refers to an aggregate of the “articles” in which a plurality of the “articles” described above are collected and collected.

  In addition, the term “binding” means, for example, that a group of articles that are merely integrated and are physically weakly integrated are bundled together. Accordingly, this includes, of course, a state in which the string-shaped binding body is wound around the group of articles and bundled together, and also includes, for example, winding a long band-shaped binding body such as a stretch film around the group of articles and physically gathering them. At this time, as a mode of the binding, the binding body may be, for example, one round (or several rounds) around the side surface of the article group and wound around only a partial circumferential region of the side surface, or may be a side surface of the article group, for example. The binding body may be wound so as to cover the whole.

Further, in the article group binding system according to the present invention,
The binding device,
A binding body for binding the group of articles;
Binding body support means for supporting the binding body,
With
The binding support means supports the binding so as to be rotatable around the article group,
It is preferable that the binding body be swung and wound around the group of articles to bind the group of articles.
Furthermore, in the article group binding system according to the present invention,
The unmanned transport device is a loading type that loads the article group thereon,
It is preferable that the article group is bound in a state of being loaded on the unmanned transport device.

  The article group bundling system according to the present invention transports an unbound state of the article group to a predetermined position using an unmanned transport apparatus, and after detecting that the article group has been transported to a predetermined position by the unmanned transport apparatus, The article group is bound by a binding device. Therefore, according to the present invention, the transport path of the article group is not fixed. Thereby, the installation layout and the number of bundling devices are not restricted as compared with the above-described method of transporting a group of articles by the belt conveyor. Therefore, according to the present invention, a series of operations including a bundling process can be performed efficiently, and the number of bundling processes per unit time of a group of articles housed in a predetermined facility can be increased. Further, according to the present invention, all the article groups to be transported can be transported by the same unmanned transport apparatus. Therefore, for example, it is not necessary to install the bundling devices by the number of types of the article group. As a result, the number of binding devices can be minimized, and the cost of equipment construction can be reduced.

The front schematic diagram of the goods group bundling system which concerns on this embodiment at the time of using another bundling apparatus. 9 is a flowchart illustrating an example of an operation up to a binding process. The schematic plan view of the conventional article group binding system.

  An article group binding system according to an embodiment of the present invention will be described in detail. Here, FIG. 1 is a schematic plan view of an article group binding system 1 according to the present embodiment. FIG. 2 is a schematic front view of the article group binding system 1 before the operation of the binding apparatus 30, and FIG. 3 is a schematic front view of the article group binding system 1 during the operation of the binding apparatus 30. As shown in FIGS. 1 to 3, an article group binding system 1 according to the present embodiment includes an unmanned transport device 10, an article group detection unit 20, and a binding device 30.

  First, the configuration and operation of the unmanned transport device 10 will be described. The unmanned transport device 10 is a vehicle-type transport device that travels automatically without a human driving operation. The unmanned transport device 10 is an union-bound article group PG (an aggregate of articles P1, P2, P3,..., Pn). ) Is transported to a predetermined position (for example, in the present embodiment, a position in the binding device 30). In addition, as shown in FIG. 2 and FIG. 3, in the present embodiment, the article group PG is loaded on the unmanned transport device 10 via the pallet PL. However, the loading format of the article group PG is not limited to this (for example, a format in which the article group PG is directly loaded on the unmanned transport device 10 without using the pallet PL).

  Although the type of the unmanned transport device 10 is not particularly limited, for example, the unmanned transport specified in “3 (1) Types of unmanned transport vehicles (a) general classification” of Japanese Industrial Standard JIS D6801 Vehicle type, unmanned towing vehicle type, unmanned forklift type and the like can be mentioned. Further, an unmanned transport device of a type that is not classified into this may be used.

  However, in the article group binding system 1 according to the present embodiment, as described later, a mode in which the article groups PG are bundled in a state where they are stacked on the unmanned transport device 10 is preferable in terms of work efficiency, binding processing speed, and the like. In order to cope with this aspect, it is preferable that the automatic guided vehicle 10 is of the automatic guided vehicle type described above. Among them, a so-called loading type that can move forward and backward (or may be able to make a turning movement) and has a low floor is preferable. Here, the loading type includes a so-called submerged type unmanned transporting device that sinks below a load to be transported (in the case of the present embodiment, an article group PG) and lifts and loads it.

  As shown in FIGS. 1 to 3, the unmanned transport device 10 according to the present embodiment is a loading type unmanned transport vehicle having a flat upper surface on which a group of articles PG is placed (as described above. , But is not limited to this.) The article group PG according to the present embodiment is placed on the flat upper surface (via the pallet PL).

  By using such a loading type unmanned transport device as the unmanned transport device 10, the binding process can be performed while the article group PG is placed on the unmanned transport device 10. Therefore, before or after the article group PG is transported to the destination and the binding processing is performed, there is no need to remove or place the article group PG from the unmanned transport device 10. Therefore, time loss due to these operations can be eliminated, and a more speedy bundling process can be performed.

  On the other hand, before the binding process, the article group PG may be separated from the unmanned transport device 10 once, and the binding process may be performed on the article group PG. In this case, a spacer member that lifts up the article group PG without interfering with the unmanned transport apparatus 10 loaded with the article group PG and separates and supports the article group PG from the unmanned transport apparatus 10 during the binding process is used. And so on. According to this aspect, while performing the binding process on one group of articles PG, the unmanned transport device 10 that has conveyed this can be used for conveying another group of articles PG.

  The means for loading the group of articles PG on the unmanned transport apparatus 10 or the means for unloading the group of articles PG from the unmanned transport apparatus 10 may be human means by an operator or mechanical means such as a forklift. It may be. Further, other means may be used.

  The guidance method of the unmanned transport device 10 is not particularly limited. However, a magnetic guidance system that can construct a guidance system at low cost, a laser guidance system that does not require a guidance medium such as guidance tape, and an autonomous vehicle that does not require a guidance medium and travels autonomously based on detection information from sensors and the like. A traveling system is preferred. Further, a plurality of guidance methods may be appropriately combined.

  For example, when traveling through various guidance media such as a magnetic guidance system or a laser guidance system, the unmanned conveyance device 10 receives an interface unit for detecting the guidance medium and detection information on the detected guidance medium from the interface unit. And a calculation unit for calculating to travel on a predetermined route based on the received information.

  Furthermore, it is preferable that the automatic guided vehicle 10 according to the present embodiment includes a storage unit that stores a program for automatic traveling and layout information in a facility such as a factory or a distribution warehouse where the automatic guided vehicle 10 travels. The calculation unit performs a predetermined calculation with reference to the storage unit. The arithmetic unit is connected to the interface unit, the storage unit, and the like via a bus, and is also electrically connected to a wheel driving mechanism, a braking mechanism, and the like of the automatic guided vehicle 10, and transmits command information for automatic traveling to these units. I do.

  In the case of traveling by the autonomous traveling method, the unmanned transport device 10 may detect (for example) detect a stop position or remove an obstacle during traveling instead of (or in addition to) the interface unit for recognizing the guidance medium. It is preferable to provide various sensors for detection. The equipped sensor is connected to the arithmetic unit via a bus, and detection information from the sensor is transmitted to the arithmetic unit. The calculation unit controls a traveling direction, a traveling speed, and the like based on the received detection information.

  The unmanned conveyance device 10 according to the present embodiment includes a light receiving unit 110 that receives at least a part of irradiation light emitted from an article group detection unit 20 (detection unit 21) described later. The light receiving unit 110 is connected to the above-described arithmetic unit via, for example, a bus. When the light receiving unit 110 receives the irradiation light, the received light information is transmitted to the calculation unit. The arithmetic unit that has received the light reception information stops the unmanned transport device 10. However, the traveling control of the unmanned transport device 10 is not limited to this.

  As described above, by using the unmanned transport device 10 as the transport means of the article group PG, the article group PG can be transported without fixing the movement route to the binding device 30. Therefore, it is not necessary to adjust the binding device to the installation position of the conveying means such as a belt conveyor. Therefore, the installation layout and the number of bundling devices are not restricted as compared with the above-described system in which the group of articles is transported by the belt conveyor. Further, a plurality of types of articles to be transported can be transported by one unmanned transport apparatus. Therefore, unlike the belt conveyor transport method described above, it is not necessary to install the binding devices for the number of types of the article group, and it is possible to reduce the facility construction cost.

  Next, the configuration and operation of the article group detecting means 20 will be described. The article group detecting means 20 is a means for detecting that the article group PG has been transported to a predetermined position (a transport destination). The article group detecting means 20 according to the present embodiment includes a detecting unit 21. The detection unit 21 in the present embodiment is an optical sensor, but is not limited thereto. Other aspects include, for example, various sensors such as a position sensor, an ultrasonic sensor, and a pressure sensor.

  The detecting unit 21 in the present embodiment includes a light projecting unit SI that irradiates light to a detection target and a light receiving unit SR that receives reflected light from a detection object that has received irradiation light from the light projecting unit SI. It is a reflection type optical sensor.

  Further, as shown in FIGS. 1 to 3, the detection unit 21 according to the present embodiment is disposed near a binding device 30 described later, and is located inside the binding device 30 (a group of articles transported by the unmanned transport device 10). Irradiation light is irradiated toward the PG. When the unmanned conveyance device 10 loaded with the article group PG is conveyed to a position facing the article group detection means 20, the unmanned conveyance device 10 or the article group PG receives irradiation light, and a part of the irradiation light is The light is reflected to the detection means 20 side. When the light receiving unit SR receives the reflected light, it detects that the article group PG has been transported to a predetermined position.

  It is preferable that the article group detecting means 20 according to the present embodiment further includes, for example, a control unit 22 connected to the light receiving unit SR. When the light receiving section SR receives the reflected light from the unmanned transport device 10 or the article group PG, the light receiving section SR transmits the received light information to the control unit 22. The control unit 22 that has received the light receiving information determines that the article group PG has been transported to the predetermined position.

  Further, as shown in FIGS. 1 to 3, it is preferable that the control unit 22 is communicably connected to a binding device 30 described later. The control unit 22 that has determined that the article group PG has been transported to the predetermined position transmits the binding processing start instruction information for instructing the article group PG to perform the binding processing to the binding apparatus 30.

  However, the mode of the detection unit 21 is not limited to this. As another mode of the detection unit 21, there is a mode in which a so-called transmission type sensor is used instead of the diffuse reflection type sensor in which the light emitting unit SI and the light receiving unit SR are integrated as described above. When a transmissive sensor is used as the detecting unit 21, the light beam from the light projecting unit SI 'to the light receiving unit SR' traverses the transport destination of the article group PG (in the present embodiment, a predetermined area in the binding unit 30). So that the light projecting part SI ′ and the light receiving part SR ′ are spaced apart from each other.

  When the unmanned transport device 10 passes between the light projecting unit SI ′ and the light receiving unit SR ′, the irradiation light from the light projecting unit SI ′ is blocked by the unmanned transport device 10 (or the article group PG) and the light receiving unit SR Do not reach '. In this state, the detection unit 21 detects the presence of the unmanned transport device 10.

  In this case, it is preferable that the light receiving section SR 'is connected to the control unit 22. As described above, when the irradiation light from the light projecting unit SI 'is blocked by the unmanned conveyance device 10 (or the article group PG) and the irradiation light does not reach the light receiving unit SR', the control unit 22 It is determined that the unmanned transport device 10 has passed between the light emitting part SI ′ and the light receiving part SR ′.

  When the article group detecting means 20 of this aspect is used, the unmanned transport device 10 may include a communication interface unit (the above-described light receiving unit 110) capable of receiving travel stop information from the control unit 22. With such a configuration, the traveling stop processing of the unmanned transport apparatus 10 can be linked with the above-described determination processing in the control unit 22 and the vicinity of the detection unit 21 (that is, in the case of the present embodiment, the unmanned transport apparatus 10). The unmanned transfer device 10 can be stopped quickly at the transfer destination 10 (in the binding device 30). However, the traveling stop control method of the unmanned transport device 10 is not limited to this. As another method, for example, a predetermined obstacle is installed at an arbitrary position in (or around) the binding device 30, and a sensor (an optical sensor, an ultrasonic sensor, or the like) is provided on the unmanned transfer device 10 side, When the unmanned transport device 10 detects the obstacle with a sensor, a method of stopping the traveling of the unmanned transport device 10 based on the detection information may be used. Other methods may be used.

  In the above description, the presence of the unmanned transport device 10 or the group of articles PG is detected by one sensor, but is not limited thereto. As another embodiment, there is an embodiment in which two or more sensors are arranged at different height positions, and the unmanned conveyance device 10 and the article group PG are detected by different sensors. According to such an embodiment, even if the unmanned transport device 10 on which the article group PG is not loaded reaches a predetermined position (transportation destination) for some reason, the binding process is not performed, and the binding process is not performed. Useless operation of the device 30 can be limited.

  Next, the configuration and operation of the binding device 30 will be described. As shown in FIGS. 2 and 3, the binding device 30 includes a binding body 310 for binding the conveyed article group PG, and a binding body support unit 320. In addition, the binding device 30 further includes a control unit KC that controls operations of the binding body 310, the binding body support means 320, and the like.

  The binding body 310 according to the present embodiment illustrated in FIGS. 2 and 3 includes a polyethylene film resin called a stretch film. In the binding body 310, the film resin is formed in a band shape, and is wound around a hollow cylindrical core material (may be coreless) such as a winding core. The starting end of the film resin is a free end, and by pulling the starting end, the film resin wound around the core material is unwound. In addition, the binding device 30 may separately include a film unwinding device including a film stretching roller.

  The binding support 320 is provided to support the binding 310. As shown in FIGS. 2 and 3, the binding body support means 320 according to the present embodiment includes a base frame 321. The base frame 321 includes a rectangular frame-shaped ceiling frame 3211 and four leg frames 3212a to 3212d extending vertically downward from four corners of the ceiling frame 3211.

  In addition, the binding body support means 320 according to the present embodiment further includes a binding body guide frame 322 to which the binding body 310 is attached and which guides the movement of the binding body 310. The binding body guide frame 322 is a plate member having a central opening and connected to the leg frames 3212a to 3212d in a substantially horizontal state with the ceiling frame 3211. Further, the binding body guide frame 322 is connected to the leg frames 3212a to 3212d via a lifting mechanism (not shown). Thereby, the binding body guide frame 322 can be moved up and down in the height direction of the binding body supporting means 320.

  The binding body 310 attached to the binding body guide frame 322 moves along the peripheral edge of the binding body guide frame 322, for example, as shown in FIGS. Thereby, the binding body 310 can be turned around the article group PG. The turning movement of the binding body 310 and the lowering movement of the binding body guide frame 322 along the leg frame 3212 are linked, and as shown in FIG. 3, the binding body (stretch film WR) is provided on at least the side surface of the article group PG. It is wound. Thereby, the article group PG is bound.

  The guide mechanism of the binding body 310 provided on the binding body guide frame 322 is arbitrary. For example, a rail portion R formed along the periphery of the binding body guide frame 322, the binding body 310 is mounted, and the rail portion A mechanism including a rail engaging portion RE that engages with R may be used. Further, the rail engaging part RE includes a driving part GD such as a motor and a driving force transmission medium such as wheels and gears connected to the driving part GD. When the driving unit GD is driven, the driving force transmission medium rotates, and the binding body 310 moves along the rail portion R.

  Here, the elevating mechanism for raising and lowering the binding body guide frame 322 and the driving unit GD for moving the binding body 310 along the rail portion R of the binding body guide frame 322 are controlled by the control unit KC of the binding device 30. Preferably, the information can be received. Based on the received operation control information, the elevating operation of the binding body guide frame 322 and the turning operation of the binding body 310 are controlled.

  However, the mode of the binding device 30 is not limited to this. Another mode of the binding device different from the above is, for example, a binding device 30 'shown in FIG. The bundling device 30 ′ includes a plastic cord-like binding body 310 ′, a binding body support mechanism 330 that supports the binding body 310 ′, and turns the binding body 310 ′ along the side surface of the article group PG. An elevating mechanism 340 for elevating and lowering the support mechanism 330 is provided.

  As shown in FIG. 4, the bundling member support mechanism 330 moves above the article group PG through a projecting piece 331 protruding from the elevating mechanism 340 toward the article group PG side and a shaft 332. It has a rotating arm 333 that rotates, and a binding holder 334 that is attached to the tip of the rotating arm 333 and that holds the binding 310 ′.

  The elevating mechanism 340 includes a base 341 that stands upright in the vicinity of the conveyed article group PG, and a drive unit 342 that moves the protruding piece 331 up and down. When winding the binding body 310 ′ around the side surface of the article group PG, the driving unit 342 drives to move the protruding piece 331 to an appropriate position, and then, with the rotation of the rotating arm 333, the binding body holding unit 334 moves the Turn the side of PG. Thereby, the binding body 310 'is wound around the article group PG and bound.

  According to the binding devices 30 and 30 ′ (hereinafter, when simply referred to as the “binding device 30”, in addition to the binding device 30, the binding device 30 ′ is included), a relatively inexpensive material can be used as the binding body. At the same time, the binding process of the article group PG can be performed without introducing a complicated operation.

  As described above, as the binding mechanism of the binding device 30, a mechanism (an example of the binding device 30) that moves the binding member 310 along the periphery of the binding member guide frame 322, or the binding member 310 with the rotation of the rotating arm 333. A mechanism for moving the '(an example of the binding device 30') is used. Therefore, when performing the bundling process on the group of articles PG loaded on the unmanned transport device 10, the unmanned transport device 10 is a stacked unmanned transport in which none of the members extend above the mounting surface of the group of articles PG. It is preferable to use a car.

  By using the loading type automatic guided vehicle, any member of the automatic guided vehicle interferes with the binding device 30, for example, the binding member 310, the rotating arm 333, the binding member holding portion 334, etc. during the binding process to the article group PG. Never do. Thereby, the binding devices 310 and 310 'can wind the binding members 310 and 310' around the article group PG without any particular operation restrictions. Therefore, the binding devices 310 and 310 'can bind the article group PG more quickly and firmly. Further, according to these binding devices, a speedy and efficient binding process can be performed in synergy with the advantage of using the above-described loading type automatic guided vehicle.

  Next, an example of a series of operations from the loading of the article group PG to the binding processing will be described with reference to FIG. As shown in FIG. 5, (S1) the articles P1, P2, P3,..., Pn are manually or mechanically moved to the width direction and the depth of the flat upper surface of the unmanned conveyance device 10 (loading type). The articles are stacked sequentially in the direction and the height direction (the stacked articles form an article group PG).

  (S2) When the loading operation of the article group PG is completed, the article group PG is transported by the unmanned transport apparatus 10 to the destination (the area inside the binding apparatus 30). (S3) In the present embodiment, when the unmanned transport device 10 loaded with the article group PG reaches the inside of the binding device 30, the detection unit 21 (article group detecting means 20) provided near the binding device 30 causes the unmanned transport. The presence of the device 10 or the article group PG is detected (detected).

  (S4) When the article group PG is detected, the detection information is transmitted from the light receiving unit SR of the detection unit 21 to the control unit 22. The control unit 22 that has received the detection information determines that the article group PG has been transported into the binding device 30.

  (S5) Subsequently, the control unit 22 that has determined that the article group PG has been conveyed transmits command information to the binding apparatus 30 to perform a binding process on the article group PG. (S6) Based on the command information, the binding body guide frame 322 of the binding device 30 descends, and the binding body 310 supported by the binding body guide frame 322 turns along the side surface of the article group PG (or In the case of the binding device 30 ', the driving unit 342 descends to a predetermined position, and the rotating arm 333 rotates, so that the binding unit 310' held by the binding unit holding unit 334 turns along the side surface of the article group PG. .).

  By this operation, the binding body 310 (310 ') turns around the article group PG and is wound around the side face of the article group PG. Finally, the article group PG is bound by the wound binding body 310 (310 '). The article group PG for which the binding process has been completed is transported by the unmanned transport device 10 to the destination of the next operation.

  At this time, if a loading type unmanned transport vehicle is used as the unmanned transport device 10, the work of unloading the article group PG from the unmanned transport device 10 during the binding process can be omitted. Further, with the omission of the unloading operation of the article group PG, the operation of reloading the article group PG on the unmanned transport device 10 after the binding process can be omitted. Therefore, according to this embodiment, a speedy and efficient binding operation can be performed.

  As described above, the article group binding system according to the present invention has been described in detail. However, the above description is for facilitating the understanding of the present invention, and is not intended to limit the present invention. The present invention includes those that can be changed and improved without departing from the gist thereof. The invention also includes equivalents thereof.
