Abstract

PURPOSE:To obtain a band guide arch for which clogging by soil or mud does not occur by a method wherein a plurality of intermittent band ways are connected with gaps in between, and from the gaps, soil, mud, etc., are discharged outside of the band ways in the opposite direction of flaps through the band ways. CONSTITUTION:A band way of a vertical arch band way 44 and/or horizontal arch band way 45 for a band guide arch 20 are divided into a plural number, and a plurality of these intermittent band ways 12 are connected with gaps in between. Therefore, even when objects to be packed such as turf or vegetables on which soil or mud has adhered are packed, the soil and mud which have dropped on an arch band way 22 are moved by a band which runs in a band passing through allowable gap, and are discharged outside of the band way in the opposite direction of flaps 25 from the gaps of the intermittent band ways 12 through the band way while being moved. At the same time, even soil and mud which have adhered on the band itself are discharged. By this method, the band guide arch 20 in which a band can pass through, and for which a troublesome cleaning is not necessary can be obtained.

Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a band guide arch in a packaging machine.

[Conventional technology]

In general, packaging machines can pack almost anything that can be wrapped around a band, and have a wide range of uses. However, some of the items to be packaged include muddy lawns and vegetables (e.g.
(Chinese cabbage, wild radish, radish, burdock, etc.), and grass in particular needs to be packaged with a large amount of mud on its roots.
The moisture content of the soil that adheres to the mud changes dramatically depending on the weather that day, such as rain or the like. When packing such muddy objects, in order to prevent the mud from falling into the band welding mechanism in the packing machine body, a band guide arch 20 as shown in FIG. 4 is used, for example. In many cases, a so-called horizontal packaging machine is used, which is installed over the side of a packaging machine main body 40 that includes a band welding mechanism 41 and a band box 42. To explain this horizontal packing machine, band guide arch 2
0, as shown in FIG. 5, an arch frame 21 is provided over the main body 40, and a series of arches consisting of a vertical arch bandway 44 and a horizontal arch bandway 45 are installed inside the arch frame 21 in the direction of the arch center. bandway 22
is fixed. A band guide 30 is installed on one side of the arch frame 21 on the side of the arch bandway 22 and erected in the direction of the center of the arch. A plurality of flaps 25 are provided on the other side of the arch frame 21 to cover approximately the entire length of the arch bandway 22 in the width direction via a spring 29 which will be described later. Flap 25 is arch frame 2
The arch bandway 22 is rotatably provided in the lateral direction via a hinge shaft 27 and a spring 29 pushed through a flap hinge 26 attached to the side surface of the arch bandway 22. Further, arch covers 23 and 24 are attached to the lower side portion of the band guide arch 20, that is, other portions other than the lower side arch 33 from the outside of the arch frame 21 in the front and rear directions. Furthermore, the horizontal packaging machine places mounting tables 35 and 36 at the front and rear of the band guide arch 20 (the front side of the sheet in FIG. The mounting table 35, 3
6 is a fixed frame 3 installed vertically on the pace to which the main body 40 is attached.
It is fixed on a movable frame 37 that can be moved up and down within 8, and the height can be adjusted freely. In this horizontal packing machine, the packing band wound around the band coil 43 attached to the packing machine main body 40 is rotated in the normal direction by a pair of feed rollers in the packing machine main body 40, so that the tip of the slide table has a convex planar shape. The band passes through a band guide that can move forward and backward, and is sent out into the band guide arch 20 installed across the packaging machine body 40 via a pool box 42 storing a predetermined amount of bands, and placed on the mounting tables 35 and 36. The tip of the band that has gone around the placed object to be packed is inserted onto a band guide that can move forward and backward below the protrusion at the tip of the slide table. When the start switch is actuated, each press block operated by a camshaft connected to a drive motor and the tip protrusion of the slide table grip the tip of the band and rotate the pair of rollers in the main body 40 in reverse order. Packing is performed by gripping the band supply end side after pulling back and tightening, inserting a heated heater between the band overlapping parts, melting the band, and cutting the band supply end. Next, the band is fed into the band passage allowable gap of the band guide arch 20 by the normally rotating roller in the main body 40, and the band tip rotates and reaches the welding mechanism 41, completing preparation for the next packing process.

[Problem to be solved by the invention]

With the band guide arch 20 in the conventional packing machine, when packing objects to be packed, such as muddy lawns and vegetables, when the objects to be packed are placed on the mounting table 35° 36,
Soil and mud fall down onto the lower arch 33. Although the arch center side of the arch bandway 22 is covered by the flap 25 via the band passage, soil and mud can be removed from the gap between the flap 25 and the band guide 30 or between the adjacent flaps 25 and 26. Infiltrate Naach Bandway 22. Furthermore, when the band is pulled back by the reverse rotation of the pair of rollers in the main body 40 and escapes from the band guide arch 20, the flap 25 rotates and the arch bandway 22 is opened, so that at this time as well,
Dirt and mud fall onto the arch bandway 22. Therefore, as the packing process is repeated, dirt and mud accumulates on the arch bandway 22 of the lower arch 33, eventually making it impossible for the band to run, so the lower arch 33 must be cleaned frequently. The problem was that it had to be done. Moreover, even if the operator rotates the flap 25 to open the arch bandway 22 while cleaning, due to the structure of the band guide arch 20, the band guide 30 and the flap 25. The soil and mud inside the arch bandway 22 cannot be easily removed, and if an attempt is made to completely clean it by washing with water, there is a problem in that each member of the packing machine is likely to rust. It was something that would happen. The present invention provides a band guide arch that does not cause dirt or mud clogging when packing objects such as lawns and vegetables that have dirt or mud attached to them, and furthermore, a band guide that can be easily attached and detached for cleaning. The purpose is to provide an arch.

[Means to solve the problem]

In order to achieve the above object, the band guide arch of the present invention includes a vertical arch bandway 44 and a horizontal arch bandway that are attached to the packing machine main body 4o and arranged to surround the packing band around the object to be packed. 45, and a spring 29 that extends approximately the entire length of the arch bandway 22 and extends approximately the entire length in the width direction of the arch bandway 22 through a band passage allowance gap.
In the band guide arch 20 equipped with a plurality of flaps 25 that can be opened and closed via the band guide arch 2o, the vertical arch bandway 44 and/or the horizontal arch bandway 45 of the band guide arch 2o are divided into a plurality of bandways,
The plurality of intermittent bandways 12 are connected through gaps, and soil, mud, etc. are discharged from the gaps to the outside of the bandways in a direction opposite to the flap 25 through the bandways. Furthermore, in the horizontal packing machine in which the band guide arch 20 is attached to the side of the packing machine main body, the bandway of the horizontal arch bandway on the lower side of the band guide arch 20 is divided into a plurality of bands, and the plurality of intermittent bandways are divided into a plurality of bands. It is effective to make the bandways 12 continuous through a gap and to bend the rear edge of the intermittent bandway in the band traveling direction downward. Further, in the band guide arch of the present invention, the vertical arch bandway 44 and/or the horizontal arch bandway 45, each of which is made up of a plurality of intermittent bandways 12 continuous through the above-mentioned gaps, are integrated into the band guide arch 2.

[Effect]

When packing items to be packed that have dirt, mud, etc. attached to them, dirt and mud that have fallen onto the arch bandway 22 of the band guide arch 20 of the packing machine are removed from the band passage allowable gap. Upon contact with the tip or band surface of the band running inside, the band moves forward and is discharged from the gap between the intermittent bandways 12 via the bandway to the bottom of the bandway. In addition, dirt, mud, etc. adhering to the band are also removed while the band travels on the bandway and are discharged from the gap. When a plurality of intermittent bandways 12 connected with gaps are provided on the horizontal arch bandway 46 at the lower side of the arch bandway 22, soil and mud do not move much;
It immediately falls below the bandway from the nearby gap. Furthermore, even when a plurality of intermittent bandways 12 connected through the gaps are provided on other vertical arch bandways 44 and/or horizontal arch bandways 45 of the arch bandway 22, soil carried by the bands and The mud or dirt adhering to the band is discharged from the gap through the bandway to the lower part of the bandway. Further, the detachably provided split arch bandway 22 can be easily removed from the band guide arch 20 for easy and complete cleaning. In addition, the divided arch bandway 32 has the volatile parts 1 at both ends.

It is regulated by the inner wall of the gap, and the longitudinal direction is regulated between the support bars 15 and 15, so that it is mounted so reliably that it is not affected by the vibrations of the packaging machine.

[Example] An example will be explained with reference to the drawings, omitting parts similar to those in the prior art. Fig. 1 shows the lower arch 33 of the band guide arch 20 of the horizontal packing machine shown in Fig. 4. 10 is a detachable split arch. This divided arch 10 is constructed by dividing the horizontal arch bandway 45 at the lower side of the arch bandway 22 of the band guide arch 20 from the arch bandway 22, and dividing this divided arch bandway 32 into a plurality of parts to form intermittent bands 12a to 12i. ,
The plurality of intermittent bandways 12a to 121 are made continuous through gaps, and the plurality of intermittent bandways 12a to 121 are
12i is attached above a split arch frame 11 which is made up of two substantially parallel plates along the width of the bandway, the lower portions of which are partially connected by a connecting plate 17. Each of the intermittent bandways 12a to 12i has its rear end edge bent downward in the band traveling direction. Further split arch 1
0 extends to the entire length of the divided arch bandway 32, and covers the entire length of the divided arch bandway 32 in the width direction through a band passage allowable gap from both sides of the divided arch bandway 32 via a spring 29. It is equipped with a flap 25. That is, the flap 25 has flap hinges 26 attached to both sides of the split arch frame 11.
It is rotatably provided in the width direction of the split arch bandway 32 via a hinge shaft 27 inserted through the spring 29 and a spring 29, and is always biased by the spring 29 so as to cover the split arch bandway 32. Furthermore, as shown in FIGS. 1 and 2, the split arch 10 is provided with support bars 15 (described later) below both ends of the split arch frame 11 in the longitudinal direction. A notch 13 is provided to be engaged so as to extend over Is, and an insertion part 14 is provided to be inserted into a gap provided in a support bracket 16 that fixes both ends of the support bar 15. As shown in FIG. 3, the insertion portion 14 is provided by a downwardly curved plate spanning the lower ends of two substantially parallel plates of the front and rear divided arch frame 11, and the width of the divided arch frame 11 is as described above. The width is the same as or slightly larger than the width of the gap provided in the support bracket 16. In this embodiment, the support bar 15 is a round bar, and as shown in FIG. 16
is bolted to. The width direction, longitudinal direction, and height direction of the divided arch 10 are as follows:
The edge of the divided arch bandway 32 is connected to the edge of the adjacent arch bandway 22 so that the band can run smoothly. The above is a horizontal bay 45 on the lower side of the band guide arch 20.
is divided from the arch bandway 22, and this divided arch bandway 32 is divided into the adjacent arch bandway 22.
Although the embodiment of the divided arch 10 provided detachably to the arch bandway 2 has been described, similarly, other vertical arch bandways 44 and/or horizontal arch bandways 45 can be attached to the arch bandway 2.
The divided arch bandway 32 can be detachably attached to the adjacent arch bandway 22 by being divided from the arch bandway 22. Then, without removably providing the vertical arch bandway 44 and/or horizontal arch bandway 45 of the band guide arch 20 divided from the arch bandway 22, a series of arch bandways can be constructed. Band guide arch 20 fixed within 22
Even this band guide arch 20 is a means that can sufficiently solve the problems of the prior art. In this case, for example, the vertical arch bandway 44 and/or horizontal arch bandway 45 of the band guide arch 20 is divided into a plurality of bandways, and the plurality of intermittent bandways 12a to 12i are made to be continuous through gaps. , and the others are the same, so the explanation will be omitted. Next, to explain the operation of this embodiment, first, when inserting the split arch 10 into the lower side of the band guide arch 20, the split arch 10 is installed between the support bars 15 and 15, and the insertion portions at both ends are 14° 14 are respectively inserted into the gaps provided in the support bracket 16, and the split arch 10
The upper sides of the cutout portions 13.13 at both ends of the split arch 1 are placed in contact with the upper sides of the support bar 15°15, respectively.
The height direction of 0 is restricted. Here, the longitudinal direction of the split arch 10 is a notch 13 that is engaged with the support bar 16.15.
. It is regulated by the part where it is worn. At this time, since the insertion portion 14 has a downwardly curved plate spanning the lower ends of two substantially parallel plates of the split arch frame 11, the split arch frame 11 is inserted into the gap of the support bracket 16. It serves as a guide when the split arch frame 11 is put on, and also functions as a spring that biases the split arch frame 11 in the direction of expanding outward. As described above, the divided arch bandways 32 of the divided arch 10 are easily and reliably attached between adjacent arch bandways 22, and a series of arch bandways 22 is formed. Next, a mounting table 36 located above the split arch 10.
When packaging items such as muddy lawns and vegetables are placed on the top of the split arch bandway 36, dirt and mud from the items are separated from the gap between the flaps 25 and 26 that cover the split arch bandway 32. Even if a small amount of soil or mud falls onto the intermittent bandway 12 of the arch bandway 32, it will be moved between the intermittent bandways 12 by contact with the tip or band surface of the band running within the band passage allowable gap. It falls below the divided arch frame 11 via the divided arch frame 11 from the gap. In other words, the band moves while sweeping away a small amount of dirt or mud that has fallen onto the intermittent bandway 12. Therefore, even if the packing work is repeated, dirt and mud will not accumulate on the intermittent bandway 12, so the band will not be unable to travel due to dirt or mud. Further, after the packing work is completed, the split arch 10 can be easily removed by simply lifting the cutout portions 13 and insertion portions 14 on both ends upward to remove them from the support bar 15 and support bracket 16. The detached divided arch 10 allows the intermittent bandway 12 to face downward, allowing easy removal of stuck soil and mud. Moreover, such detachable split arch 10 has a simple structure,
Moreover, since it is an independent and relatively small structure, the cost is low even if it is made of a corrosion-resistant material such as stainless steel, and since it can be washed with water, it can be completely cleaned. When a plurality of intermittent bandways 12 connected with gaps are provided on the horizontal arch bandway 45 at the lower side of the arch bandway 22 as described above, the fallen soil and mud will not pass over the intermittent bandways 12. A plurality of intermittent bandways 12 that do not move and immediately fall below the bandway from the gap but are connected through the gap are connected to other vertical arch bandways 44 of the arch bandway 22.
And or when installed on the horizontal arch bandway 45, the soil and mud carried by the band running on the arch bandway 22 below the object to be packed, or the soil and mud attached to the band, are removed from the gaps between the intermittent bandways 12. It is discharged from the bandway through the bandway to the bottom of the bandway. The band guide arch 20 fixed within the series of arch bandways 22 without detachably providing the split arch bandway 32 has the same effect as when the split arch bandway 32 is attached, so it is omitted. do.

【Effect of the invention】

Since the present invention is configured as described above, it produces the effects described below. Divide the vertical arch bandway of the band guide arch and/or the bandway of the horizontal arch bandway into multiple parts,
Since these multiple intermittent bandways are connected with gaps in between, even if items to be packaged such as lawns and vegetables that have soil or mud attached to them are packed, the soil or mud that falls onto the arch bandway will not be removed. While moving by the band running within the band passage allowable gap, it is discharged from the gap between the intermittent bandways through the bandway to the outside of the bandway in the opposite direction of the flap, and at the same time even dirt and mud attached to the band Therefore, it was possible to provide a band guide arch through which the band can pass without requiring complicated cleaning. Furthermore, in a horizontal packing machine in which a band guide arch is attached to the side of the packing machine main body, the bandway of the horizontal arch bandway on the lower side of the band guide arch is divided into a plurality of bands,
This structure in which a plurality of intermittent bandways are connected with gaps in between is effective because soil and mud that has fallen from the packaged items can easily fall downward from the 8# between the intermittent bandways with a short distance of movement. . Furthermore, the rear edge of the intermittent bandway in the band traveling direction is bent downward to further facilitate band travel. In addition, a vertical arch bandway and/or a horizontal arch bandway consisting of a plurality of intermittent bandways connected through gaps are each integrally divided from the band guide arch, and this divided arch bandway is attached to and detached from the adjacent arch bandway. Since it is freely installed, dirt and mud can be easily and completely cleaned, and only this split arch bandway can be made of corrosion-resistant material such as stainless steel.
It was possible to provide an inexpensive band guide arch that can be washed with water. Furthermore, support brackets each having a gap into which a support bar for supporting the divided arch bandway and both sides of the divided arch bandway in the width direction are inserted are provided on the arch bandways adjacent to both ends of the divided arch bandway. , a cutout portion that engages with the support bar is provided on both ends of the split arch bandway, and an insertion portion that can be inserted into the gap of the support bracket by being biased so as to be in contact with the gap at all times; It has a simple structure and is removable.
It was possible to provide a band guide arch that can be easily removed and washed with water, and that can be reliably attached without being affected by the vibrations of a packaging machine.
