Description

  The present invention relates to a packaging device with an arch guide that reduces the frictional resistance of a tape traveling in a tape running groove of an arch guide and improves the feeding (forward rotation) of the tape.

  The arch guide packing device with an arch guide around the table rotates the drive roller that clamps the tape with the idler, feeds the tape into the tape running groove of the arch guide, and runs around the arch guide. Hold the tip of the tape, reverse the drive roller and pull it back, remove the tape from the arch guide and drop it, reverse the drive roller further, pass the tape around the package on the table, tighten it, and then tighten the tape It is comprised so that a package may be packed by cutting | disconnecting. In addition, although this kind of apparatus is also called a binding machine, a band hanging machine, etc., the packing apparatus of this case is a general term for this kind of apparatus including a binding machine, a band hanging machine, etc. Similarly, a tape that is wrapped around a package to pack the package is also referred to as a band, but the tape in this case refers to the concept including the band.

  The arch guide is a portal type that combines a straight portion and a corner portion. The arch guide includes inner and outer tape guides facing each other, and is formed between the inner and outer tape guides facing the tape running groove. Normally, the outer tape guide is fixed, the inner tape guide is movable, and the inner tape guide escapes to the left and right (side) in synchronization with the pulling back of the tape so as not to prevent the tape from dropping, or it is pushed by the tape. It is configured to swing open. However, if the tape can fall through the gap of the inner tape guide due to the flexibility of the tape, the inner tape guide is not movable.

  Since the tape travels while being guided by being in contact with the inner and outer tape guides, the tape is fed into the tape running groove, so that it receives frictional resistance due to contact with the inner and outer tape guides and generates static electricity due to the frictional resistance. The frictional resistance and static electricity hinder the feeding of the tape and hinder smooth feeding. Depending on the quality of the tape, the tape may be clogged. Here, the tape is pulled back by the reverse rotation of the drive roller, whereas the tape is fed by the normal rotation of the drive roller. Therefore, the feeding of the tape is referred to as the normal rotation of the tape.

  For example, the inner tape guide may be molded from a material with low friction resistance or covered with a sheet with low friction resistance so that the tape can be fed smoothly without reducing frictional resistance and static electricity generation. In Japanese Utility Model Publication No. 6-034252, it is described that an ethylene tetrafluoride resin sheet is attached to a rubber plate or a laminated sheet of synthetic resin fibers is attached to a synthetic resin layer to form an inner tape guide. . In Japanese Utility Model Laid-Open No. 7-037901, the inner and outer tape guides are integrated into a U-shaped cross section, and a low friction material liner is incorporated to reduce the frictional resistance. The integral tape guide escapes to the left or right to open the tape in it.

  In Japanese Utility Model Laid-Open No. 61-040303, a tetrafluoroethylene resin sheet is affixed to an outer tape guide. The tape then strikes the outer tape guide at the corner of the arch guide and changes its feeding direction. Therefore, paying attention to the fact that large static electricity is generated by receiving a large frictional resistance at the corner portion, a V-shaped projection is formed on the outer tape guide at the corner portion, and the projection is also covered with a tetrafluoroethylene resin sheet. In this configuration, when the tape is fed over the protrusion, the tape rises in the vicinity of the protrusion and does not contact the outer tape guide, so that the frictional resistance at the corner portion is reduced and the generation of static electricity is suppressed.

  However, when the inner and outer tape guides are formed from a material having a low frictional resistance or a resin sheet or the like is attached, the tape guide becomes expensive. Also, instead of molding the inner and outer tape guides with a material with low frictional resistance, it is possible to reduce the frictional resistance by applying Teflon (registered trademark) processing to the surface of the inner and outer tape guides, but the tape guide is expensive. There will be no change. Furthermore, even if a tetrafluoroethylene resin sheet or the like is affixed to the inner and outer tape guides, or the surface of the inner and outer tape guides is processed with Teflon (registered trademark), the resin sheet or Teflon (registered trademark) processed surface can be used after long-term use. Peeling off, the effect of which decreases significantly over time.

  In the configuration in which the protrusion is formed on the outer tape guide at the corner, the formation of the outer tape guide becomes complicated due to the presence of the protrusion. Further, the protrusions are strongly rubbed against the tape, and the protrusions are worn out in a short period of time as well as the resin sheet covering the protrusions, and the effect is not maintained for a long time. In Japanese Utility Model Laid-Open No. 7-024701, in consideration of the wear of the protrusion, the influence of the wear is eliminated by replacing the protrusion with a metal pin and replacing the metal pin. However, since the metal pin is attached to the outer tape guide, the outer tape guide has a special shape, and this makes the molding of the outer tape guide complicated.

In this way, the inner and outer tape guides are molded from a material with low frictional resistance, a resin sheet or the like is applied, Teflon (registered trademark) processing is applied to the surface, protrusions or metal pins on the outer tape guide at the corners In the known configuration in which the friction resistance is reduced and the generation of static electricity can be suppressed, the effect is short-lived and is not an essential solution. Even though the effect cannot be maintained for a long time, the inner and outer tape guides are molded from a material with low frictional resistance, resin sheets are used, special processing is applied, etc. High price is invited.

  The problem to be solved is that there is no inexpensive packaging device with an arch guide that maintains the effect of reducing frictional resistance and suppressing the generation of static electricity for a long period of time.

  In the known configuration, emphasis is placed on reducing the frictional resistance of the tape by changing the material of the inner and outer tape guides that contact the tape, sticking the resin sheet, changing the contact surface by Teflon (registered trademark) processing, changing the shape, etc. The contact surface itself that generates frictional resistance is not considered at all. On the other hand, in the present invention, focusing on the fact that there is less frictional resistance if there are fewer contact surfaces, the emphasis is placed on reducing the contact surface itself of the tape guide inside and outside the tape, enabling the contact surface with the tape The most important feature is to form the inner and outer tape guides in as few shapes as possible.

  According to the first aspect of the present invention, the inner tape guide and the outer tape guide are each formed in a shape that guides only the right and left edges of the tape, and the minimum necessary contact surface is prepared for the inner and outer tape guides. However, the frictional resistance that the tape receives from the inner and outer tape guides is reduced, and the generation of static electricity is suppressed. Therefore, the tape is smoothly fed into the arch guide and travels, and the tape forward rotation is improved. Then, it is sufficient if the contact surface has a necessary minimum shape, and the inner and outer tape guides can be easily formed, so that an arch guide can be obtained at a low cost. Since the arch guide can be obtained at a low cost, the packaging device is also inexpensive. And the effect is also maintained for a long time.

  According to the second aspect of the present invention, the inner tape guide and the outer tape guide are respectively formed in a shape that guides only the left and right edges of the tape and are integrated, and the minimum necessary contact surface is provided. Only the inner and outer tape guides are prepared, and the frictional resistance that the tape receives from the inner and outer tape guides is reduced, thereby suppressing the generation of static electricity. Therefore, the tape is smoothly fed into the arch guide and travels, and the tape forward rotation is improved. Then, it is sufficient if the contact surface has a necessary minimum shape, and the inner and outer tape guides can be easily formed, so that an arch guide can be obtained at a low cost. And the effect is also maintained for a long time. Since the outer tape guide and the inner tape guide are integrated and movable, the tape can be easily centered (positioned).

  According to the third aspect of the present invention, only the minimum necessary contact surface is provided in the arch guide, the tape contacts the outer tape guide at the left and right ends thereof, and the inner tape guide is a wire. Therefore, the contact with the inner and outer tape guides is small because the contact with the inner tape guide is merely prevented from coming off from the tape running groove. Therefore, the tape is smoothly fed into the arch guide and travels, and the tape forward rotation is improved. Also, the inner and outer tape guides can be easily formed, and the arch guide can be obtained at a low cost. And the effect is also maintained for a long time.

  According to the fourth aspect of the present invention, since both the inner and outer tape guides are wire rods, the tape is guided in line contact with the outer tape guide at the left and right ends thereof, and the tape is guided to the inner tape guide. The contact is only prevented from coming off from the tape running groove, the contact surface with the inner and outer tape guides is small, the frictional resistance that the tape receives from the inner and outer tape guides is reduced, and the generation of static electricity is suppressed. Therefore, the tape is smoothly fed into the arch guide and travels, and the tape forward rotation is improved. The inner and outer tape guides made of wire are also formed at low cost, and the arch guide can be obtained at low cost. The effect is also maintained for a long time.

  The purpose of reducing the frictional resistance and suppressing the generation of static electricity is maintained for a long period of time, and the purpose of constructing the packing device with an arch guide at a low cost without increasing the cost is to reduce the contact surface with the tape as much as possible. This is realized by forming a tape guide.

  FIG. 1 shows a schematic front view of a packaging device with an arch guide according to the present invention. As can be seen from FIG. 1, the packing device 10 is configured to include a device main body 16 whose upper surface is a table 14 on which a package 12 is placed, and an arch guide 18 arranged around the table, and a tape is fed into the packing device 10. A tape running groove 20 that runs along the arch guide is formed. In addition, inside the apparatus main body 16, the drive roller that feeds the tape and pulls it back and tightens it, holds the tip of the tape around the arch guide and holds it, pulls the tape back and hangs around the package, and then tightens the tape A fusing mechanism for fusing the motor, a motor for driving the drive roller, and the like are housed, but since they are not directly related to the present invention, descriptions of those constituent members are omitted.

  The arch guide 18 is configured in a portal shape in which a straight portion 18a and a corner portion 18b are combined, and the inner and outer tape guides 22 and 24 (see FIGS. 2 and 3) positioned facing each other are either a straight portion or a corner portion. The tape running groove 20 is formed between the inner and outer tape guides facing each other. A part (bottom part) of the arch guide 18 is also located in the apparatus main body 16 below the table 14.

  2 and 3 are cross-sectional views of the arch guide 18 taken along lines aa and bb in FIG. 1, and show a cross-sectional shape of the arch guide at the straight line portion and the corner portion. As will be described later, in the linear portion, the inner tape guide is slidable (movable), FIGS. 2A and 2B show the state before and after the slide, and FIG. 2C shows the outer tape. The top view of a guide is shown.

  As shown in FIG. 2C, the outer tape guide 22 of the arch guide 18 has a guide portion 22a that guides only the left and right edges of the tape 11, for example, is formed in a fork shape, and the inner tape guide 24 is The outer tape guide is formed by being divided into shapes having left and right edges 24a having substantially the same length as the guide portion 22a. Therefore, in the straight part of the arch guide 18, the tape running groove 20 is formed between the guide part 22 a of the outer tape guide and the edge part 24 a of the inner tape guide, and the tape 11 is formed only on the left and right edges. The tape guide 22 and the inner tape guide 24 can be contacted, and the central portion of the tape does not contact the outer tape guide and the inner tape guide.

  The guide portion 22a of the outer tape guide and the edge portion 24a of the inner tape guide having substantially the same length are formed as small as possible so that the tape 11 fed into the tape running groove 20 does not leave the tape running groove during running. Thus, the contact surface of the outer tape guide and the inner tape guide with respect to the tape 11 is minimized. Therefore, frictional resistance due to contact with the outer tape guide 22 and the inner tape guide 24 is reduced, and generation of static electricity is suppressed as much as possible. Therefore, the tape 11 is smoothly fed into the linear portion of the arch guide and travels in the tape travel groove 20 to improve the normal rotation of the tape.

  Then, if the outer tape guide 22 is formed into a shape with a guide portion 22a and the inner tape guide 24 is formed into a shape having edge portions 24a on the left and right, the contact surface with the tape is minimized, and such a shape is formed. Can be easily performed without requiring a complicated process, and the arch guide 18 can be obtained at low cost. If the arch guide 18 is obtained at a low cost, the packaging device 10 is naturally obtained at a low cost. Then, it is only molded into a shape that makes the contact surface smaller, and it does not reduce the frictional resistance by applying a resin sheet, Teflon (registered trademark) processing on the surface, etc. The effect of suppressing is maintained for a long time without significantly decreasing with time.

  When the tape 11 is pulled back, in synchronization with it, as shown in FIG. 2B, the inner tape guide 24 escapes to the left and right (side), and a large gap is formed between the left and right edges 24a of the inner tape guide. The tape falls off the arch guide 18 through the gap.

  As described above, in the linear part of the arch guide 18, the inner tape guide 24 is divided and molded, and is movable to the left and right. However, in the corner portion, it is not necessary to form the inner tape guide from the wire and make the inner tape guide 24 movable. That is, as shown in FIG. 3A, the outer tape guide 22 is formed in a shape with a guide portion 22a that holds the left and right edge portions of the tape 11 and guides the running of the tape. It is formed from a wire that is installed facing the guide portion 22a of the tape guide and prevents the tape from being detached. A steel wire such as a piano wire can be used as the wire. Further, for the soft tape 11, a durable synthetic resin wire (for example, tennis racket, badminton racket gut, fishing line) can be used.

  Also in this configuration, the outer tape guide 22 has a shape that holds the left and right edge portions of the tape 11 and guides the running of the tape, for example, a shape with a guide portion 22a, and the guide portion guides the running of the tape. Molded to the smallest possible length in the range. The contact of the tape 11 with the inner tape guide 24 made of a wire is only a line contact. Therefore, the contact surface at the corner portion is small, the frictional resistance received from the inner and outer tape guides 22 and 24 is small, the generation of static electricity is suppressed, and the tape 11 is smoothly fed into the corner portion of the arch guide and runs. Forward rotation is improved. And it is sufficient if it is a shape that holds the left and right end portions of the tape 11 and guides the running of the tape. The outer tape guide can be easily molded, and the inner tape guide made of a wire can be easily installed. The configuration can be easily performed without requiring a complicated process, the arch guide 18 can be obtained at a low cost, and the packaging device 10 is not expensive. In addition, the contact surface is simply molded into a shape that does not reduce frictional resistance by attaching a resin sheet or processing Teflon (registered trademark) on the surface. The effect is maintained for a long time without significantly decreasing over time.

When a pulling force is applied to the tape 11, the tape is pressed against the inner tape guide 24 and elastically deforms, passes through the gap between the inner tape guides, and falls off the arch guide 18 (see FIG. 3A).
As described above, when the wire is the inner tape guide 24, the tape 11 can be detached by slipping through the inner tape guide, and there is no need to make the inner tape guide movable. Therefore, when a pulling back force is applied to the tape 11, a mechanism for moving the inner tape guide synchronously becomes unnecessary at the corner portion, the configuration is simplified, and the arch guide 18 and the packing device 10 can be obtained at low cost. However, if necessary, the inner tape guide 24 may be movable.

  As can be seen from FIG. 3 (B), the wire rod (inner tape guide) 24 is bent and the bent piece 24b is inserted into the mounting hole 25a of the frame plate 25 and installed. In FIG. 3 (B), only one wire rod (inner tape guide) 24 is shown in order to avoid complication of the drawing, but the wire rod is erected on the side wall of the frame plate 25 having a U-shaped cross section. It can be easily understood from FIG. 3A that the wire is attached to the corner portion of the arch guide.

  The configuration in which the wire is used as the inner tape guide 24 can also be applied to the outer tape guide 22. That is, as shown in FIG. 4A, not only the inner tape guide 24 but also the outer tape guide 22 can be made of a wire. Here, the inner tape guide 22 can be formed from a total of two wires, one on each side. However, in order to ensure a guide length that can guide the feeding and running of the tape 11 reliably, the number and arrangement positions of the outer tape guides 22 are considered in consideration of the strength of the tape waist and the diameter of the wire. For example, it is formed from a total of four wires, two on each side.

  The configuration of the arch guide 18 in which both the outer tape guide 22 and the inner tape guide 24 are formed from the wire can be employed not only in the corner portion but also in the straight portion. In this configuration, the contact between the tape 11 and the inner and outer tape guides 22 and 24 is a line contact, the frictional resistance that hinders the feeding of the tape is minimized, and the generation of static electricity is suppressed as much as possible. The tape is smoothly fed into both the straight portion and the corner portion and travels in the tape running groove 20, so that the tape forward rotation is greatly improved. Further, when a pulling back force is applied to the tape 11, a mechanism for moving the inner tape guide 24 in synchronization is not required in both the corner portion and the straight portion, the configuration is simplified, and the arch guide 18 and the packing device 10 are It can be obtained inexpensively.

  When forming the outer tape guide 22 from the wire material, the wire material is not directly installed, but as shown in FIG. 4 (A '), an engagement groove 22c is formed in the guide portion 22a of the outer tape guide, and a part thereof protrudes. It is good also as a structure which makes it engage and engage a wire with an engaging groove. In this configuration, a step of forming the engaging groove 22c is added to the guide portion 22a, but a slight process is sufficient, and the cost is not increased.

  The configuration in which the tape 11 contacts the fixed outer tape guide 22 and the movable inner tape guide 24 only at the left and right edges thereof is not limited to the configuration shown in FIG. For example, as shown in FIG. 5A, the outer tape guide 22 has a substantially U-shaped cross section with an outer flange 22a, and a tape guide groove between the outer flange 22a and the edge 24a of the inner tape guide. 20 may be configured.

  Also in this configuration, the tape 11 can come into contact with the outer tape guide 22 and the inner tape guide 24 only at the left and right edges, and the central portion of the tape does not come into contact with the outer tape guide and the inner tape guide. The guide portion 22a of the outer tape guide and the edge portion 24a of the inner tape guide having substantially the same length are as small as possible so that the tape 11 fed into the tape running groove 20 does not leave the tape running groove during running. Formed. Therefore, the contact surfaces of the outer tape guide 22 and the inner tape guide 24 with respect to the tape 11 are minimized, the frictional resistance due to contact with the outer tape guide and the inner tape guide is reduced, the generation of static electricity is suppressed as much as possible, and the straight line of the arch guide is reduced. The tape 11 is smoothly fed into the portion (side portion) and travels in the tape running groove 20 to improve the tape forward rotation. Here, when the divided inner tape guide 24 escapes to the left and right and a large gap is formed between the left and right edge portions 24a, the tape 11 is released from the arch guide 18 through the gap and falls. Not so long (see FIG. 5B).

  2 and 5, the outer tape guide 22 is fixed, and only the inner tape guide 24 is movable. However, the outer tape guide 22 and the inner tape guide 24 may be integrated, and the integrated tape guide 224 may be movable left and right. In this case, for example, the tape guide 224 is formed into a U-shaped cross section (see FIG. 6) or a shape having two guide portions 224a provided facing each other (see FIG. 7). FIGS. 6A and 7B show the state of the movable inner tape guide before and after sliding. The configuration in which the outer tape guide 22 and the inner tape guide 24 are integrated and movable to the left and right is advantageous in that centering (positioning) with respect to the tape 11 can be easily performed as compared to a known configuration that is movable to either the left or right. There is.

  A configuration in which the outer tape guide 22 and the inner tape guide 24 hold only the left and right edges of the tape 11 and minimize the contact surface of the outer tape guide and the inner tape guide with respect to the tape 11 without using a wire (FIG. 2). 5, 6, and 7) are not limited to the straight portion of the arch guide 18, and can be adopted at the corner portion.

  A configuration (FIGS. 3 and 4) in which the inner tape guide 24 is made of a wire material or both the outer tape guide 22 and the inner tape guide 24 are used, and the outer tape guide 22 and the inner tape guide 24 are It goes without saying that the straight part and the corner part of the arch guide may be configured by combining with the structure (FIGS. 2, 5, 6, and 7) that holds only the left and right edge parts.

  As described above, according to the present invention, the inner and outer tape guides are formed in a shape that reduces the contact surface with the tape as much as possible by using a wire, etc. Therefore, the tape is smoothly fed and traveled, and the normal rotation of the tape is improved. And, it is sufficient if the contact surface has a minimum necessary shape, and it is easy to form the inner and outer tape guides, so that the arch guide can be obtained at a low cost and the cost of the packaging device 10 is not increased. The effect is also maintained for a long time.

  The above-described embodiments are for explaining the present invention, and do not limit the present invention. All modifications, alterations, and the like within the technical scope of the present invention are included in the present invention. It goes without saying that it is done.

  The technical idea of the present invention can be widely applied as a configuration for reducing frictional resistance in a field where static electricity due to frictional resistance becomes an obstacle.
