TECHNICAL FIELD OF THE INVENTION
The present invention relates to a banding device and a banding method for banding an object to be packed loaded on a pallet together with the pallet and fixing it to the pallet.
[0002]
[Prior art]
When transporting an object to be packed using a forklift, the object to be packed is generally loaded on a pallet. A pallet used for such an application has a plurality of girder members arranged in parallel with each other, and a plate member hung over at least the upper surface of the girder members, and the upper surface of the plate member is an object to be packed. Loading surface. Further, even when the pallet is placed on the floor, a space extending from one side end of the pallet to the other side end (hereinafter, also referred to as a pallet lower space) is formed between adjacent beam members. The forklift fork can be inserted into the forklift.
[0003]
Here, when the objects to be loaded on the pallet are large and heavy items to be packed, or when they are small and stacked in multiple stages, etc. In order to do so, it has been practiced to band these pallets together with the pallets and fix them to the pallets. In many cases, such banding work is performed manually. Specifically, a band is passed through the space under the pallet of the pallet on which the package is loaded, and the band passed through the space under the pallet is wrapped around the package on the pallet to bind the pallet and the package. I do. Here, in order to pass the band through the space under the pallet, the operator had to fall down to a position near the floor. In addition, since the band is made of flexible plastic, it is difficult to move the band straight in the space under the pallet, and performing the banding work with the waist lowered is a heavy burden on the worker. .
[0004]
Therefore, in order to reduce the burden on the operator, Patent Document 1 discloses a configuration in which a through groove is formed in the loading surface of the pallet and the object to be packed can be lifted up relative to the loading surface of the pallet. A device for assisting a banding operation on the object to be packed by allowing the band to pass along the through groove in a state where the object to be packed loaded on the loading surface of the pallet is lifted up is disclosed. ing.
[0005]
In addition, there are facilities for automatically performing banding. This equipment includes an arm mechanism having an arm that holds the tip of the band and enters the space under the pallet, and a transport unit that transports the packaged object to the arm mechanism together with the pallet. The loaded pallet is transported to the arm mechanism by the transport mechanism, and the band is passed through the space under the pallet by the arm mechanism.

[0007]
[Problems to be solved by the invention]
According to the apparatus for lifting up a packaged object as described in Patent Literature 1, the burden on the worker is reduced. However, this type of apparatus involves a problem that the efficiency of the entire banding operation is reduced because the apparatus involves the operation of lifting and lowering the article to be packed. On the other hand, the transport mechanism in the conventional equipment in which the band is passed through the space below the pallet by the arm transports the article to be packed together with the pallet, and the arm mechanism requires a space for moving the arm. I do. Therefore, the equipment itself becomes large, or a large space is required for installing the equipment.
[0008]
Therefore, an object of the present invention is to provide an apparatus and a method for strapping articles to be packed, which can efficiently strap with a simple configuration while reducing the burden on the worker.
[0009]
[Means for Solving the Problems]
In order to achieve the above object, in the banding apparatus of the present invention, a plate member is fixed on at least an upper surface of a plurality of girder members, and is mounted on a pallet in which a space is formed between adjacent girder members. What is claimed is: 1. A device for strapping an article to be wrapped around a band, the moving means for advancing and retreating the tip of a steel strip, and the tip of the advancing steel strip having one opening (inlet) of the space. And a feeding means for guiding the steel strip to travel along the same space, and changing the traveling direction of the tip of the steel strip sent out from the other opening (exit) of the same space upward. Having a direction changing means, wherein the moving means, after the end of the band is locked to the tip of the steel strip whose traveling direction has been changed by the direction changing means, at least the end of the band from the entrance. Until the above is pulled out Characterized in that retracting the tip of the band. Therefore, all operations other than locking the end of the band to the end of the steel strip sent out from the outlet are performed automatically, and the time and labor required for banding are greatly reduced. The burden of is also greatly reduced. In addition, since the band is wrapped around the elongated steel strip as a guide without moving the pallet or the articles loaded thereon, the apparatus is not enlarged, and the forward and backward directions of the tip of the steel strip are optimized. This makes it possible to make the device as small as possible.
[0010]
According to the banding method of the present invention for achieving the above object, a plate member is fixed on at least the upper surface of a plurality of girder members, and is stacked on a pallet having a space formed between adjacent girder members. A banding method of a packaged object for wrapping a band around the packaged object, wherein a tip of a steel strip is fed into the space from one opening (entrance) of the space, and the other opening (exit). ), The step of locking the end of the band to the tip of the steel strip sent from the outlet, and the end of the band locked to the tip of the steel strip is withdrawn at least from the inlet. And a step of retracting the tip of the steel strip. Therefore, the time and effort required to hang the band is greatly reduced, and the burden on the operator is greatly reduced as compared with the case where the band made of flexible plastic is passed directly through the above space. I do.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a schematic side view of a banding apparatus for a packaged object according to an embodiment of the present invention. 1 is a convex steel used for passing a band 70 through a space under a pallet of a stage 5 installed on a floor surface F and a pallet 50 placed on the stage 5. The elevating unit 10 as a moving means for moving the belt 18, a feeding mechanism 20 as a feeding means for moving the convex steel strip 18 moved by the elevating unit 10 along the space under the pallet, and has passed through the space under the pallet. It has a direction changing mechanism 30 as direction changing means for changing the traveling direction of the convex steel strip 18 upward.
[0012]
The pallet 50 is placed on the stage 5, and an article to be packed 60 is loaded on the pallet 50. The pallet 50 has basically the same configuration as a conventionally used pallet. Specifically, as shown in FIG. 2, it has a plurality of spar members 51 arranged in parallel with each other at intervals and a deck board 52 which is a plate member laid over the upper and lower surfaces thereof, respectively. A space 54 under the pallet is formed between the deck boards 52 along the longitudinal direction of the spar member 51. Although FIG. 2 shows the pallet 50 in which the deck boards 52 are provided above and below the beam members 51, the deck boards 52 may be provided only on the upper surface of the beam members 51. Although the deck board 52 is shown as a single plate member above and below the beam member 51, the deck board 52 may be composed of a plurality of plate members arranged to intersect with the beam member 51.
[0013]
Referring again to FIG. 1, the elevating unit 10 includes an arm 15 for suspending and supporting the convex steel strip 18 and an elevating mechanism 14 for elevating the arm 15. Further, the elevating unit 10 is linearly movable in the vertical direction by a guide support member 13 provided on a frame 12 of the apparatus 1 (only the parts necessary for the description of the present embodiment are shown in FIG. 1). It also has a lift guide 17 supported.
[0014]
The elevating guide 17 is a rod-shaped member having a longitudinal direction in its moving direction. The upper end of the elevating guide 17 penetrates the arm 15 and protrudes above the arm 15, and the upper end of the elevating guide 17 protruding above the arm 15 is provided with a stopper 16 that comes into contact with the upper surface of the arm 15. The vertical movement of the elevating guide 17 downward is restricted. Therefore, as shown in FIG. 3, when the operator operates a switch (not shown) to operate the elevating mechanism 14 and lower the arm 15, the elevating guide 17 has its lower end surface (butting end surface 17a) on the floor surface. It descends by its own weight together with the arm 15 until it comes into contact with F. However, the arm 15 continues to descend independently to the predetermined position even after the abutment surface 17a of the elevating guide 17 strikes the floor surface F and cannot descend any more.
[0015]
As shown in FIG. 4, the convex steel strip 18 is a steel strip whose cross section along the width direction is formed in an arc shape. Such a convex steel strip 18 is often used for a tape measure made of steel, and can be bent with a relatively small force to the concave surface 18a side due to its cross-sectional shape, but to the convex surface 18b side. It has the property of being difficult to bend. In the present invention, this property of the convex steel strip 18 is used, and in order to effectively use this property, in the present embodiment, the convex steel strip 18 has its concave surface 18a attached to the packaged object 60. It is hung on the arm 15 toward the side.
[0016]
At the tip of the convex steel strip 18, a band fixing part 11 is provided. As shown in FIG. 5, the band fixing portion 11 is a plate-like member having a width substantially equal to that of the convex steel strip 18, and a middle portion in the longitudinal direction of the band fixing portion 11 is hooked with a tip of a band 70 (see FIG. 1). A slit 11 a capable of locking the band 70 to the band fixing portion 11 by being wound or wound is formed.
[0017]
The tip of the convex steel strip 18 is held by the feed mechanism 20 in the state shown in FIG. Here, the feed mechanism 20 will be described with reference to FIG. FIG. 6A is an enlarged side view of the feed mechanism 20 shown in FIG. 1, and FIG. 6B is a plan view thereof. The feed mechanism 20 includes a fulcrum roller 21, a lateral guide roller 22, and a support roller 23, which are rotatably provided at the lower end of the elevating guide 17, respectively. The lateral guide roller 22 comes into contact with the convex surface 18b of the convex steel strip 18 fed between the fulcrum roller 21 and the lateral guide roller 22 to hinder the vertical movement of the steel strip 18 and to make the contact portion horizontal. A stress to bend in the direction is applied. The fulcrum roller 21 is in contact with the concave surface 18a opposite to the convex surface 18b with which the lateral guide roller 22 is in contact, and supports the contact point where the above-mentioned stress is acting from the inside. Thus, the convex steel strip 18 fed between the fulcrum roller 21 and the lateral guide roller 22 is bent toward the pallet 50 with the fulcrum roller 21 as a fulcrum. Furthermore, the support roller 23 supports the convex steel strip 18 bent toward the pallet 50 from below by passing between the fulcrum roller 21 and the lateral guide roller 22, and the bent convex steel strip 18 is elastically linearly bent. In addition to restricting the return, the delivery height of the convex steel strip 18 is adjusted to the position of one opening (the inlet 54a) of the space 54 under the pallet. Therefore, when the arm 15 further descends from the state shown in FIG. 3, that is, when the arm 15 continues to descend independently after the abutting surface 17a of the elevating guide 17 abuts against the floor F, the tip of the convex steel strip 18 becomes The pallet is fed into the space 54 from the entrance 54a of the space 54 under the pallet by the feed mechanism 20. When the arm 15 continues to descend further, as shown in FIG. 7, the convex steel strip 18 advances along the space 54 under the pallet, and passes through the opening on the opposite side (the outlet 54 b). It is sent out of the space 54. In addition, flanges are provided on the outer periphery of the fulcrum roller 21, the lateral guide roller 22, and the support roller 23 to prevent the convex steel strip 18 from being displaced in the width direction or falling off.
[0018]
Referring again to FIG. 1, a direction changing mechanism 30 is provided on the opposite side of the elevating unit 10 with respect to the stage 5, and the convex steel strip 18 that has passed through the space under the pallet as described above is moved in this direction. The conversion mechanism 30 converts the traveling direction upward. Here, the direction change mechanism 30 will be described with reference to FIG. FIG. 8A is an enlarged side view showing a standby state of the direction changing mechanism 30 shown in FIG. 1, and FIG. 8B is an enlarged side view showing an operating state. The direction changing mechanism 30 includes a receiving roller 31 provided at an end of the stage 5 and an upper guide roller 32 provided on the floor F, which is ahead of the receiving roller 31 in the traveling direction of the convex steel strip 18. The upper guide roller 32 is rotatably attached to the tip of the rod 34 of the air cylinder 33, and moves up and down in conjunction with the raising and lowering of the arm 15 shown in FIG. Specifically, the arm 15 further descends from the state shown in FIG. 7, and the tip of the convex steel strip 18 sent out from the outlet 54 b of the space 54 under the pallet has a predetermined length above the standby state shown in FIG. After passing over the guide roller 32, the rod 33 is extended and the upper guide roller 32 is lifted upward. The upper guide roller 32 lifted upward contacts the convex surface 18b of the convex steel strip 18 from below, and pushes the steel strip 18 upward as shown in FIG. 8B. The receiving roller 31 contacts the concave surface 18a of the convex steel strip 18 pushed up as described above, and regulates the pushing up of the steel strip 18. As described above, the convex steel strip 18 that has entered between the upper guide roller 32 and the receiving roller 31 is bent upward with the receiving roller 31 as a fulcrum, and its traveling direction is changed upward as shown in FIG. You. Here, the elevating operation of the upper guide roller 32 in conjunction with the elevating operation of the arm 15 is controlled based on the detection result of the optical arm position sensor 19 shown in FIG. That is, the arm position sensor 19 has at least a light source (not shown) and a light receiving unit (not shown) that receives light emitted from the light source. By blocking the light incidence, it is detected that the arm 15 has dropped to a predetermined position. The predetermined position is set at a position where the tip of the convex steel strip 18 passes over the upper guide roller 32 by a predetermined length. Therefore, when the arm position sensor 19 detects that the arm 15 has dropped to the predetermined position, the air cylinder 33 automatically operates, and the rod 34 is extended by a predetermined length. In addition, flanges can be provided on the outer periphery of the receiving roller 31 and the upper guide roller 32.
[0019]
Referring to FIG. 1 again, a band roll 71 in which a band 70 is wound around a core material is rotatably suspended on the opposite side of the stage 5 from the elevating unit 10. When the band fixing portion 11 provided at the tip of the convex steel strip 18 whose traveling direction has been turned upward as described above approaches the band roll 71 to a predetermined distance, the lifting mechanism 14 stops automatically or manually. Then, the arm 15 also stops at that position.
[0020]
After the lifting mechanism 14 is stopped as described above, the tip of the band 70 is manually wound around the slit 11a (FIG. 5) of the band fixing portion 11, as shown in FIG. Thereafter, when the operator operates a switch (not shown) to operate the elevating mechanism 14 and raise the arm 15, the stopper 16 of the elevating guide 17 comes into contact with the upper surface of the arm 15 which has been raised to a predetermined position. Numeral 15 rises to a predetermined position while lifting the elevating guide 17. The elevating mechanism 14 is automatically or manually stopped when the arm 15 is raised to a predetermined position, and the arm 15 also stops at that position. As shown in FIG. 10, the upward movement of the arm 15 as described above causes the convex steel strip 18 to retreat and be pulled back into the lower pallet space 54 from the outlet 54 b, whereby the band 70 is sequentially moved from the band roll 71. It is paid out. When the arm 15 further moves up, as shown in FIG. 11, the tip of the band 70 held by the band fixing portion 11 passes through the space under the pallet 54 and is drawn out from the inlet 54a. When the ascending arm 15 blocks light from entering the light receiving portion of the arm position sensor 19 again, the rod 34 is contracted, and the upper guide roller 32 descends. Thus, the movement of the convex steel strip 18 and the band 70 is not hindered by the upper guide roller 32, and the convex steel strip 18 and the band 70 are smoothly drawn into the space 54 under the pallet, and the space 54 is smoothly moved. Move (retreat). The timing at which the ascending arm 15 blocks light from entering the light receiving portion of the arm position sensor 19 again (the timing at which the arm 15 is returned to the standby position of the upper guide roller 32) is determined by at least the band fixing portion 11 pulled back to the pallet lower space 54. It is set before passing over the upper guide roller 32.
[0021]
After the leading end of the band 70 is pulled out from the entrance 54a of the pallet lower space 54, the rear end side (the band roll 71 side) of the band 70 is cut at a predetermined position, and the rear end of the band 70 formed by this cutting is cut. And the tip of the band 70 removed from the band fixing portion 11 are bound on the packaged object 60. As described above, the pallet 50 and the article to be packed 60 are banded together.
[0022]
Another embodiment of the present invention
The receiving roller can be provided at the end of the pallet. FIG. 12 shows an example of the pallet 50 provided with the receiving roller 31. The pallet 50 shown in FIG. 12 has the same configuration as the pallet 50 shown in FIG. 2 except that the receiving roller 31 is provided, and the same components are denoted by the same reference numerals.
[0023]
FIG. 11 shows an example in which the tip of the band 70 is pulled up to the side of the article 60 to be packed, but the arm 15 can be raised higher, and the tip of the band 70 is It is also possible to change the design so that it can be pulled up.
[0024]
The lifting mechanism may be configured to lower the arm to a predetermined position and stop when a switch (not shown) is operated once, and to raise the stopped arm to the predetermined position when the switch is operated again. it can. Further, the arm may be continuously lowered or raised while the switch is pressed, and the arm may be stopped when the switch is released, or may be configured differently. In the above-described embodiment, the case where the arm position sensor capable of detecting that the arm has passed the predetermined position is provided, and the upper guide roller is moved up and down based on the detection result of this sensor has been described. However, a limit switch may be arranged on the lifting path of the arm, and the upper guide roller may be raised and lowered when the limit switch is hit by the arm that has been raised or lowered to a predetermined position. Further, the arm position sensor described in the above embodiment detects only whether or not the arm has passed a predetermined position. However, the sensor which can always monitor the movement amount (elevation amount and descent amount) of the arm. It can also be. In this case, the lifting and lowering of the arm, the stopping thereof, and the raising and lowering of the upper guide roller can be controlled based on the movement amount of the arm detected by the arm position sensor.
[0025]
The moving means for moving the convex steel strip may be a mechanism other than an elevating mechanism and an arm which is moved up and down by the elevating mechanism. For example, a drive source such as a motor, a feed roller that is rotationally driven by the drive source, and a passive roller that presses the convex steel strip against the feed roller, the feed roller is rotated forward and reverse to rotate the feed roller. The mechanism may be such that the tip of the convex steel material sent between the and the passive roller is advanced and retracted as described above.
[0026]
FIG. 13 shows another example of the feed mechanism for feeding one end of the convex steel strip into the space under the pallet and for moving the fed steel strip along the space. The feed mechanism 20 shown in FIG. 13 includes a cylindrical guide 80 attached to the lower end of the elevating guide 17. This guide 80 is bent 90 degrees toward the pallet lower space side (not shown) in the longitudinal direction, and the convex steel strip 18 fed from above in FIG. It is bent toward the lower space. Further, the direction changing mechanism can have the same configuration as the guide 80.
[0027]
FIG. 14 shows another example of a direction changing mechanism for changing the traveling direction of the convex steel strip sent from the space under the pallet upward. The basic configuration of the direction changing mechanism 30 shown in FIG. 14 is the same as that of the direction changing mechanism 30 shown in FIGS. The difference is that the upper guide roller 32 is rotatably mounted on the front end of an L-shaped support member 91 rotatably mounted on an end side surface of the stage 5 by a shaft pin 90, and the rear end of the support member 91 is an air cylinder. By moving the upper guide roller 32 in the direction indicated by the arrow 92 in FIG. 14, the upper guide roller 32 can be reciprocated between the position indicated by the solid line and the position indicated by the virtual line in FIG. The effect of the reciprocating movement of the upper guide roller 32 is the same as the effect of the upper guide roller 32 shown in FIGS. 8A and 8B, and the timing of the reciprocating movement is also shown in FIGS. This is the same as the upper guide roller 32 shown in b).
[0028]
【The invention's effect】

It is sent into the space and sent out from the other opening (outlet). Further, after the end of the band is locked to one end of the steel strip sent out from the outlet, one end of the steel strip is retracted at least until the end of the band is pulled out from the inlet. Therefore, all operations other than locking the end of the band to one end of the steel band sent from the outlet are automatically performed, and the time and labor required for banding are greatly reduced, and The burden of is also greatly reduced.
(2) Further, since one end of the traveling steel strip is fed into the space under the pallet from the entrance and guided to travel along the same space, the steel strip is easily and reliably moved. To the space below the pallet.
(3) Further, since there is provided a direction changing means for changing the traveling direction of one end of the steel strip sent out from the outlet upward, the worker locks the end of the band to one end of the steel strip. Can perform the locking operation without lowering the waist or bending the waist.
(4) A steel strip having an arc-shaped cross section in the width direction bends relatively easily in a specific direction, but has a property that it is relatively hard to bend in other directions. Therefore, when such a steel strip is provided, when the steel strip is fed into the space below the pallet from the inlet or when the traveling direction of the steel strip sent from the outlet is changed upward, the steel strip is It bends smoothly in the desired direction, and the feeding and the direction change are easily and reliably performed. In other situations, since the steel strip exhibits excellent straightness, the steel strip can be easily and reliably advanced or retracted in a desired direction. In particular, the advance and retreat of the steel strip in the space under the pallet are easily and reliably performed.
(5) In the method of banding an article to be packed according to the present invention, one end of a steel strip having excellent straightness as compared with the band is connected to one opening (inlet) of the space under the pallet of the pallet on which the article to be packed is loaded. And one end of the fed steel strip is sent out from the other opening (outlet) of the space below the pallet. Further, the end of the band is locked to one end of the steel strip sent from the outlet, and the end of the steel strip to which the end of the band is locked is retracted at least until the end of the band is pulled out from the inlet. . Therefore, the time and labor required to hang the band is greatly reduced and the burden on the operator is greatly reduced, as compared with the case where the band made of flexible plastic is passed directly through the space under the pallet. To decrease.
(6) If the steel strip further includes a step of bending the steel strip halfway in the longitudinal direction and directing the traveling direction of one end of the steel strip toward the entrance, the steel strip is surely fed into the space under the pallet, The fed steel strip can be easily and reliably advanced in the space under the pallet.
(7) Further, in the case where the steel strip sent out from the outlet is further bent in the longitudinal direction and the traveling direction of one end of the steel strip is changed upward, the end of the steel strip is connected to one end of the steel strip. An operator who locks the part can perform the locking operation without lowering the waist or bending the waist.
(8) In addition, if a steel strip having an arc-shaped cross section in the width direction having a property that it bends relatively easily in a specific direction but is relatively hard to bend in another direction is used, When feeding the steel strip from the inlet into the space under the pallet or when changing the traveling direction of the steel strip sent out from the outlet upward, the steel strip is smoothly bent in a desired direction to facilitate the feeding and the direction change. And it can be executed reliably. In other situations, the steel strip exhibits excellent straightness, and can easily or reliably advance or retreat in a desired direction. In particular, advance and retreat in the space under the pallet can be executed easily and reliably.
