A preferred embodiment of the present invention will be described in detail below with reference to the accompanying drawings. In the present specification and the drawings, components having substantially the same functional configuration are designated by the same reference numerals, so that duplicate description will be omitted. The embodiments described below show typical embodiments of the present invention, and the scope of the present invention is not narrowly interpreted by this. Even when it is described in the present specification that the band hanging device according to the present invention exerts a plurality of effects, the band hanging device according to the present invention may exert at least one effect. The effects described herein are merely exemplary and not limited, and various modifications are possible and may have other effects.

The present invention will be described in the following order.
1. 1. Configuration of band hanging device according to one embodiment of the present invention 2. Cross band hanging process 3. 4. Operation method of the band hanging device according to the embodiment of the present invention. Configuration of ancillary device of band hanging device according to one embodiment of the present invention

1. 1. Configuration of Banding Device According to One Embodiment of the Present Invention The configuration of the banding device 10 according to the embodiment of the present invention will be described below with reference to the drawings.
The band hanging device 10 according to the first embodiment is a device for hanging a plurality of bands B on the packaged PI (for example, cross-hanging, cross-shaped hanging, etc.). That is, the band hanging device 10 is, for example, a device for hanging a plurality of bands B including the first and second bands B1 and B2 intersecting each other on the packaged PI.

As an example, the band hooking device 10 includes a transport portion 100, a band hooking portion 200, and at least one contact member 300 (for example, first and second contact members 310-1), as shown in FIGS. It includes 310-2) and a control unit 500.

(Transport section)
The transport unit 100 is a device for transporting the packed object PI on the transport path TP, and can transport the packed object PI to either one side or the other side in the direction in which the transport path TP extends.
The transport unit 100 is, for example, a conveyor (for example, a roller conveyor, a belt conveyor, etc.), and transports the object to be packed PI on the upper surface of the transport unit 100 (at least a part of the transport path TP). As will be described later, since the object to be packed PI is conveyed and brought into contact with the contact member 300 to change the direction (see FIG. 3), the contact surface with the object to be packed PI can be reduced and the frictional force generated between the contact surfaces can be reduced. A roller conveyor that can be made smaller is preferable.
As an example, the upper surface of the transport portion 100 has a portion extending linearly, and the band hooking portion 200 has a band hooking position BP on which the band B is hung on the packaged PI.

(Band hanging part)
The band hanging portion 200 is a device (band hanging machine) for hanging the band B on the packaged object PI. More specifically, the band hooking portion 200 hangs the band B on the packed object PI located on the transport path TP by orbiting, welding, and cutting the band B.
The band B winding direction by the band hooking portion 200 is a direction in which the packed object PI is orbited around the transport path TP by the transport unit 100.
Examples of the band B include a polypropylene band, a nylon band, a paper band, an iron band, and the like.
As an example, the band hooking portion 200 is provided in the middle of the upper surface of the transport portion 100 (for example, an intermediate portion). The band hanging portion 200 may be provided at one end of the upper surface of the transport portion 100.

As an example, the band hooking portion 200 includes a band mount 200a, a band guide gate 200b, a delivery / winding mechanism 200c, a band welding portion 200d, and a band cutting portion 200e. A commercially available band hanging machine may be used as the band hanging portion 200.

As an example, the band guide gate 200b is made of an arch-shaped member and is installed on the band pedestal 200a so as to straddle both sides in the width direction of the transport path TP. The packaged material PI can be carried in and out of the band guide gate 200b by the transport unit 100.

The sending / winding mechanism 200c is a mechanism capable of sending and winding the band B to the band induction gate 200b.
The band B on the supply side (for example, a band wound in a roll shape) is arranged in a space where the band B can be sent out and wound up, for example, in the space of the band stand 200a.

The band welding portion 200d welds the overlapping portion of the band B circulated around the packaged object PI in the space of the band pedestal 200a.
As an example, the band welding portion 200d is configured to include a pair of sandwiching members in which the overlapping portions of the bands B are arranged so as to be sandwichably opposed to each other and the sandwiched overlapping portions are heated and welded.

The band cutting portion 200e cuts the band B on the supply side.
As an example, the band cutting portion 200e has a cutter and a cutter driving unit (for example, a solenoid) that moves the cutter up and down.

In the band hanging portion 200 configured as described above, the band B is sent out into the band guide gate 200b by the sending / winding mechanism 200c, and the band B is circulated around the packaged object PI. Next, the upper and lower overlapping portions of the band B are sandwiched by the band welding portion 200d, the band B is wound by the sending / winding mechanism 200c, and the packaged PI is wound by the band B. Finally, after the supply side band is cut by the cutter of the band cutting portion 200e, the upper and lower overlapping portions of the band B sandwiched by the band welding portion 200d are heat welded.

(Contact member)
The contact member 300 is a member capable of contacting the packed object PI transported on the transport path TP, and contacts the banded and transported packed object PI to change the direction of the packed object PI. Therefore, the contact member 300 is arranged in the direction in which the packed object PI is conveyed from the band hanging position BP.
The contact member 300 does not have to lose the balance of the packaged object PI when it comes into contact with the packaged object PI. As an example, the contact member 300 is an elongated member (for example, a columnar member, a rod-shaped member, etc.), and the longitudinal direction is the transport path TP. It is provided so as to be substantially vertical to. The shape of the contact member 300 may be, for example, a cylindrical shape, a prismatic shape, or the like. If the contact member 300 has a cylindrical shape, it can make line contact with the packaged object PI, so that the packaged object PI can be rotated by approximately 90 ° with one contact member 300. The contact member 300 may have either a solid structure or a hollow structure. It is preferable that at least a part of the contact member 300 is a rigid body.
As an example, the contact member 300 is arranged so as to come into contact with a position deviated from the center in the width direction of the front surface, which is the downstream surface of the packaged PI in the transport direction, or the rear surface, which is the upstream surface in the transport direction. ing. When the packaged object PI comes into contact with the contact member 300 while being conveyed, it rotates about a vertical axis with the contact portion as an axis. As a result, the orientation of the packaged PI changes. Further, as an example, the contact member 300 is arranged so as to be in contact with at least the central portion from one end in the height direction of the front surface or the rear surface of the packaged object PI. It is preferable that the arrangement of the contact member 300 can be changed depending on the size of the object to be packed PI.

The contact member 300 may be a single contact member 300, or may be provided in a plurality of contact members 300 at intervals in a direction intersecting in a direction in which the transport path TP extends, as shown in FIGS. 1 and 2. When a plurality of contact members 300 are provided, the drive unit 400 that moves the contact members 300 other than the contact member 300 that first contacts each contact member 300 or the packaged PI between the contact position CP and the retracted position RP, which will be described later. is necessary. It is preferable to have a drive unit 400 for driving each contact member 300 so that both the band intersecting with each other and the band in one direction can be hung. Further, it is preferable that two contact members 300 are provided so as to be separated from each other in the width direction of the transport path TP. As a result, the packaged PI can be rotated around the two axes during the orientation change process, and the packaged PI can be rotated by approximately 90 ° in a space-saving manner.

As an example, the contact member 300 is a cylinder rod (hereinafter, also referred to as “cylinder rod 300”) of a cylinder device 310 (for example, cylinder devices 310-1, 310-2) such as an air cylinder or a hydraulic cylinder. In the cylinder device 310, the cylinder rod 300 (for example, cylinder rods 300-1 and 300-2) has a drive unit 400 (for example, drive unit 400-) described later with respect to the cylinder case 350 (for example, cylinder cases 350-1 and 350-2). It can be driven by 1, 400-2).

As an example, the cylinder device 310 has substantially the same longitudinal direction in the vertical direction. The cylinder device 310 is movable (movable up and down) between the contact position CP in which the cylinder rod 300 contacts the packaged object PI transported on the transport path TP and the retracted position RP retracted from the contact position CP. It is arranged so as to be. The cylinder device 310 may be installed above the transport path TP, or may be installed below the transport path TP, and the cylinder rod 300 as a contact member projects from below the transport path TP to above the transport path TP. It may be possible.

As an example, the cylinder device 310 is fixed to a support frame 330 and / or a band guide gate 200b provided so as to straddle both sides of the transport path TP in the width direction on the transport end position TEP side of the band guide gate 200b. There is. Although the support frame 330 is provided separately from the band guide gate 200b here, it may be provided integrally with the band guide gate 200b. Further, as an example, the cylinder device 310 is arranged at a position deviated from the center in the width direction of the transport path TP. Further, as an example, the cylinder device 310 may be placed on the front surface (for example, the surface on the downstream side in the transport direction) or the rear surface (for example, the surface on the upstream side in the transport direction) of the packed object PI to which the cylinder rod 300 is transported on the transport path TP. It is preferably arranged so as to be in contact with the majority of the front surface or the majority of the rear surface.

Here, as an example, the band hanging device 10 has a plurality of (for example, two) cylinder devices 310 (for example, cylinder devices 310-1, 310-2). The cylinder device 310-1 is fixed to, for example, the support frame 330, and the cylinder device 310-2 is fixed, for example, to the band guide gate 200b. The cylinder device 310-1 has a cylinder rod 300-1 (first contact member 300-1) that is first contacted in order to change the orientation of the banded object PI. The cylinder device 310-1 is arranged at a predetermined distance from the band guide gate 200b, and even if the cylinder rod 300-1 is located at the contact position CP1, it affects the transportation of the packed material PI to the band hanging position BP. do not. Preferably, the cylinder device 310-1 is arranged so that the cylinder rod 300-1 comes into contact with the packed object PI when the packed object PI is located at the band hanging position BP during the first band hanging process. To do. As a result, it is possible to shorten the time from the first banding process to the contact of the packaged PI with the contact member 300-1 during the orientation change process. Further, during the second band hanging process, the cylinder device 310-1 is arranged so that the cylinder rod 300-1 comes into contact with the packed object PI when the packed object PI is located at the band hanging position BP. Is preferable. As a result, the packed material PI is substantially in contact with the cylinder rod 300-1 at the end of the first banding process, at the start and end of the orientation change process, and at the start of the second banding process. , It becomes easy to detect whether the packaged PI is being transported normally. By bringing the banded PI to be packed into contact with the cylinder rod 300-1 while transporting it from the band hanging position BP, the banded PI can be rotated around the cylinder rod 300-1.

The cylinder device 310-2 is separated from the cylinder device 310-1 in the direction in which the transport path TP extends, and is further arranged at a position closer to the band guide gate 200b than the cylinder device 310-1. The cylinder device 310-2 has a cylinder rod 300-2 (second contact member 300-2) to be contacted next to the cylinder rod 300-1 in order to change the direction of the banded object PI. When the packaged object PI is transported to the band hanging position BP, the cylinder device 310-2 interferes with the transport of the packed object PI, so the cylinder rod 300-2 is positioned at the retracted position RP2. After the packaged PI is conveyed while being in contact with the cylinder rod 300-1, the packaged PI completely passes below the cylinder device 310-2 in which the cylinder rod 300-2 is located at the retracted position RP2. , The cylinder rod 300-2 is moved to the contact position CP2. After that, by transporting the packed object PI so as to return it to the band hanging position BP, the packed object PI can be brought into contact with the cylinder rod 300-2 and rotationally moved around the cylinder rod 300-2.

(Control unit)
As shown in FIG. 4, the control unit 500 is electrically connected to each of the transport unit 100 and the band hanging unit 200. Further, the band hooking device 10 may further include a drive unit 400, a position detection unit 600, and the like, as will be described in detail later. The control unit 500 may be further electrically connected to each of the drive unit 400, the position detection unit 600, and the like.
The control unit 500 is realized by hardware including, for example, a CPU, a chipset, and the like.
As an example, the control unit 500 executes the first banding process, the orientation changing process, and the second banding process once on the packaged PI in this order, as will be described in detail later. Hang a cross band on the packaged PI. The control of each component (conveying unit 100, band hanging unit 200, driving unit 400, etc.) at this time may be based on the operation of the operator, the time, or the detection by the position detecting unit 600. It may be based on the result (detection result of each sensor), or these may be combined.
(Other configurations)
As an example, the band hanging device 10 may further include a driving unit 400, a position detecting unit 600, and the like, as shown in FIGS. 1 to 3.

(Drive part)
The drive unit 400 moves the contact member 300 between the contact position CP and the retracted position RP. By having the drive unit 400, the contact member 300 can be positioned at the contact position CP or the retracted position RP as needed, so that a band hook for hanging bands intersecting each other and a band in one direction can be used. Both band hanging can be carried out. Further, by having the drive unit 400, a plurality of contact members 300 can be installed. For example, by installing two contact members 300, the packed object PI can be rotationally moved by two axes during the orientation change process, and the packed object PI can be rotated by approximately 90 ° in a space-saving manner.
As an example, the drive unit 400 is a part of the cylinder device 310, makes the cylinder rod 300 movable with respect to the cylinder case 350, and drives the cylinder rod 300 between the contact position CP and the retract position RP. As a driving method, for example, there is a method of adjusting the internal pressure of the cylinder case 350. When a contact member other than the cylinder rod is used, as a drive unit for driving the contact member up and down, for example, a linear motor, a combination of a rack and pinion mechanism and a drive source (for example, a motor), a ball screw mechanism and the like. A combination with a drive source (for example, a motor) or the like can be used.

(Position detector)
The position detection unit 600 detects the position of the packaged object PI on the transport path TP and transmits a signal to the control unit 500. By having the position detection unit 600, it is possible to detect whether or not the packaged object PI is normally transported. Further, the position detection unit 600 controls the start / stop / end of the first banding process, the orientation changing process, and the second banding process, and each component unit (conveying unit 100, banding unit 200, driving unit). It can also be used for control of 400 etc.).
The position detection unit 600 preferably has at least one sensor for detecting the packaged object PI at the band hanging position BP. At least one of the sensors is located adjacent to the contact member 300 that is first contacted to turn the banded packed material PI so that it can detect whether the packed material PI is being transported normally. It is preferable to be done. When a plurality of contact members 300 are provided, it is more preferable that at least one sensor is arranged at a position adjacent to each contact member 300. As an example, at least one sensor is arranged on each side of the band guide gate 200b in the transport direction. The position detection unit 600 may be able to change the position of the sensor according to the size of the packaged PI. The sensor may be an optical sensor including a light receiving / receiving unit, or another sensor (for example, an ultrasonic sensor) as long as it can detect the PI to be packed.

As an example, the position detection unit 600 includes a plurality of sensors (for example, first to fourth sensors 600a, 600b, 600c, 600d) as shown in FIGS. 2 and 3. As shown in FIG. 2, the first to fourth sensors 600a to 600d are arranged above the transport path TP along the transport path TP. Each sensor emits light downward, and if there is an object to be packed PI below, the sensor receives the reflected light from the PI to be packed (in a detection state).

The first sensor 600a is arranged at a position where the packaged PI at the transport start position TSP (for example, one end of the transport path TP) on the transport path TP can be detected.
As shown in FIG. 3, the second to fourth sensors 600b to 600d are arranged at positions on both sides of the band guide gate 200b in the transport direction. More specifically, the second sensor 600b is arranged at a position on the transport start position TSP side with respect to the band guidance gate 200b. In the control unit 500, when the packaged object PI on which the first band B1 is hung changes its direction and is carried into the band hanging position BP for the second band hanging process, the control unit 500 is charged at the timing when the carrying-in is completed. Since the sensor 600b of the above is in the detection state, the transfer is stopped at that timing. The third and fourth sensors 600c and 600d are arranged at positions on the transport end position TEP side with respect to the band guidance gate 200b. The third sensor 600c is arranged adjacent to the contact member 300-2, and the fourth sensor 600d is arranged adjacent to the contact member 300-1. In the control unit 500, the third sensor 600c is in the non-detection state at the timing when the packaged object PI on which the first band B1 is hung is removed from below the contact member 300-2 during the orientation change process. At that timing, the contact member 300-2 is moved between the retracted position RP2 and the contact position CP2. When the packaged object PI is carried into the band hanging position BP for the first band hanging process, the control unit 500 sets the fourth sensor 600d in the detection state at the timing when the carrying is completed. Stop the transportation. Further, in the fourth sensor 600d, when the contact member 300-1 and the packaged PI are at the end of the first banding process, at the start of the orientation change process, at the end of the orientation change process, and at the start of the second banding process. It is a sensor that detects contact.
By using the second to fourth sensors 600b, 600c, and 600d arranged as described above, it is possible to measure the timing of stopping the transportation when the packaged PI is carried into the band hanging position BP. It is possible to detect whether or not the packaged PI is normally transported, and it is also possible to measure the timing of moving the contact member 300-2 between the retracted position RP2 and the contact position CP2.

2. 2. Cross-banding process Hereinafter, the cross-banding process performed by using the banding device 10 will be described with reference to the flowchart of FIG. Here, the band hanging device 10 functions as, for example, a cross band hanging machine (specifically, an automatic cross band hanging machine). The cross band hanging process is an example of a band hanging method carried out by using the band hanging device 10 of the present invention. The control unit 500 starts the cross banding process, for example, when the operator performs a process start operation via the operation unit (when a process start signal as an operation signal is received).

In the first step S1, the control unit 500 executes the first banding process. The details of the first banding process will be described later.

In the next step S2, the control unit 500 executes the direction change process. The details of the orientation change processing will be described later.

In the next step S3, the control unit 500 executes the second banding process. The details of the second banding process will be described later.

In the final step S4, the control unit 500 determines whether or not to end the process. The determination here is affirmed, for example, when the operator performs a processing end operation via the operation unit (when the control unit 500 receives the processing end signal as an operation signal). If the determination in step S4 is affirmed, the flow ends, and if denied, the process returns to step S1.

Hereinafter, the first banding process (step S1 in FIG. 5) will be described with reference to the flowchart of FIG. 6, the cross-sectional views of FIGS. 7 to 9, and the front view of FIG.
Regarding the contact member 300, as shown in FIG. 10, in the initial state, the first contact member 300-1 is located at the contact position CP1 and the second contact member 300-2 is located at the retracted position RP2.
It is assumed that the packaged material PI to be processed is automatically or manually delivered to the transport start position TSP on the transport path TP at any time.

In the first step S11, the control unit 500 controls the transport unit 100 to carry the packaged object PI into the band hanging position BP. Specifically, when the control unit 500 receives the detection signal from the position sensor 600a, the control unit 500 starts the transfer of the packaged PI located at the transfer start position TSP (see FIG. 7), and the position sensors 600c and 600d detect. When the state is reached, the transportation of the packed object PI is stopped and the packed object PI is positioned at the band hanging position BP (see FIG. 8). At this time, the packaged object PI is in contact with the first contact member 300-1.

In the next step S12, the control unit 500 controls the band hanging unit 200 to hang the first band B1 on the packaged PI (see FIG. 9).

Hereinafter, the orientation change process (step S2 in FIG. 5) will be described with reference to the flowchart of FIG. 11, the cross-sectional views of FIGS. 12 to 18, and the front view of FIG.
In the first step S21, the control unit 500 controls the transport unit 100 to bring the packaged object PI on which the first band B1 is hung into contact with the first contact member 300-1. Change the orientation of the package PI.
Specifically, the packed PI is transported while the widthwise end of the front surface (the surface on the downstream side in the transport direction) of the packed PI is in contact with the first contact member 300-1. At this time, the packaged PI generates a moment around the vertical axis due to the pressing force from the first contact member 300-1, and rotates around the vertical axis (see FIGS. 12 to 14). At this time, when the packaged object PI comes off from below the second contact member 300-2, that is, when the position sensor 600c changes from the detected state to the non-detected state, the transportation of the packaged object PI is completed. (See FIG. 14).
In the next step S22, the control unit 500 controls the drive unit 400-2 to move the second contact member 300-2 from the retracted position RP2 to the contact position CP2 (see FIG. 15).
In the next step S23, the control unit 500 controls the transport unit 100 to bring the packaged object PI into contact with the second contact member 300-2 while transporting the packaged object PI toward the band hanging position BP, and the packaged object PI. Change the orientation of the PI (see FIG. 16).
Specifically, the packaged PI is conveyed while the end portion in the width direction of the rear surface (the surface on the band hanging position BP side) is in contact with the second contact member 300-2. At this time, the packaged PI generates a moment around the vertical axis due to the pressing force from the second contact member 300-2 and rotates around the vertical axis (see FIGS. 16 and 17), and is approximately 90. When rotated by °, the pressing force becomes substantially 0, and the rotary motion ends (see FIG. 17). The rotation angle of the packaged PI at this time is ideally 90 °, but it may be slightly deviated from 90 °. Further, the object to be packed PI at this time may be in contact with both the first contact member 300-1 and the second contact member 300-2. At this time, the position sensors 600c and 600d are in the detection state.

Specifically, the control unit 500 conveys the packed object PI in the reverse direction from the state shown in FIG. 17 and stops the packed object PI when the second sensor 600b is in the detection state. The packaged object PI is positioned at the hand hanging position BP (see FIGS. 18 and 19). At this time, the position sensors 600b, 600c, and 600d are all in the detection state.

The orientation change process can also be performed using only one contact member 300. In this case, steps S22 and S23 are omitted. Specifically, in step S21, even if the packed object PI is no longer located below the second contact member 300-2, the transportation is continued, and the packed object PI moves the first contact member 300-1. Transport until rotated approximately 90 ° to the shaft. After that, in step S24, the packed object PI is carried into the band hanging position BP.
Further, as the orientation changing process executed by using one contact member 300, there is also the following method. The first contact member 300-1 is moved to the retracted position RP1, the packaged object PI on which the first band B1 is hung is conveyed, and the first contact member 300-1 is passed under the first contact member 300-1. After that, the first contact member 300-1 is moved to the contact position CP1 and the packaged object PI is brought into contact with the first contact member 300-1 while being conveyed in the band hanging position BP direction to bring the packaged object PI. Rotate it by about 90 ° and carry it into the band hanging position BP.

Hereinafter, the second banding process (step S3 in FIG. 5) will be described with reference to the flowchart of FIG. 20 and the cross-sectional views of FIGS. 21 to 23.
In the first step S31, the control unit 500 controls the band hanging unit 200 to hang the first band B1 and put the second band B2 on the packaged PI (see FIG. 21) whose orientation has been changed. Multiply (see FIG. 22). As a result, a cross band composed of the first and second bands B1 and B2 is hung on the packaged PI.

In the next step S32, the control unit 500 controls the transport unit 100 to transport the packaged object PI on which the cross band composed of the first and second bands B1 and B2 is hung from the band hang position BP to the transport end position. Carry out for TEP (see FIG. 23). The control unit 500 determines that the packaged PI is located at the transport end position TEP when a predetermined time has elapsed after the fourth sensor 600d is in the non-detection state.
The packed material PI located at the transport end position TEP is automatically or manually ejected from the transport end position TEP.
