Description

  The present invention relates to a tape supply device for supplying an adhesive tape to a device for applying an adhesive tape, and a sealing device for sealing an opening of a box made of corrugated paper or the like.

  Conventionally, a box made of cardboard is used as a box for storing articles. In the case of corrugated cardboard, the opening is closed by a flap, and an adhesive tape is attached to the butt portion of the flap to form a bottom portion or a top plate portion.

  For example, Patent Document 1 discloses a sealing device that automatically performs a sealing operation in which an adhesive tape is attached to a butt portion of a flap as described above. The sealing device of Patent Document 1 stands by at a position where it comes in contact with a tape mounting portion to which a tape roll of adhesive tape is mounted and a front end face of a box conveyed in a predetermined direction, and is pulled out from the tape It has a taping unit provided with a sticking roller for pressing and sticking an adhesive tape to a butt portion of a flap of a box, and a cutter unit for cutting the adhesive tape at a predetermined length.

  In this taping unit, an adhesive tape is attached to the butt portion of the flap of the box formed of the conveyed cardboard paper, and the sticking roller presses the adhesive tape to the butt portion of the flap. Thereby, the adhesive tape fixes the butt portion of the flap. Then, the cutter unit cuts the adhesive tape with a predetermined length, and prepares to seal the box to be conveyed next. In this way, the taping unit automatically seals a box formed of corrugated paper which is sequentially fed.

  The tape winding body is attached to the taping unit. Therefore, every time a fixed number of sealing operations are performed, it is necessary to replace the tape winding body. When replacing the tape winding of the taping unit, the sealing operation is stopped. Therefore, the work efficiency is reduced. Therefore, in Patent Document 1, two tape units are provided, and the tape unit can be replaced without stopping the transport device by replacing the tape unit when it is used up. is there.

Patent No. 4064389

  However, in the case of the configuration of Patent Document 1, two taping units are required, and a moving mechanism for moving the taping units is also required. Therefore, the structure of the sealing device becomes complicated, and the sealing device itself becomes large. In addition, when moving the taping unit, it is necessary to position the adhesive tape and the butting portion of the flap of the box transported each time it is moved, so that the accuracy required for the moving mechanism and the movement control of the moving mechanism are controlled. The required accuracy is increased.

  Therefore, in view of the problems as described above, the present invention does not require complicated structure and control, and it is possible to replace the tape winding on which the adhesive tape is wound without stopping the operation of the sticking device. It aims at providing a tape supply device.

  In order to achieve the above object, the tape feeding device of the present invention is a tape feeding device for feeding the adhesive tape to a sticking device that performs a tape sticking operation of sticking an adhesive tape to an object, which is an adhesive tape. A first tape storage portion rotatably storing a wound first tape roll, and a second tape roll which is disposed side by side with the first tape storage portion and is different from the first tape roll. One of the second tape storage unit stored, the adhesive tape pulled out from the first tape roll, and the adhesive tape pulled out from the second tape roll are passed as a supply adhesive tape, and the other is put on standby adhesive A tape rejoining unit for holding the leading end of the standby adhesive tape as a tape, a tape delivery unit for delivering the supplied adhesive tape to the sticking device, and the supplied adhesive tape And the tape reattaching unit, when the remaining amount detecting unit detects that the remaining amount of the supplied adhesive tape is less than or equal to a predetermined amount, the supply is performed. The rear end portion of the adhesive tape and the front end portion of the standby adhesive tape are pasted to connect the supply adhesive tape and the standby adhesive tape, and a tape reconnection operation is performed to reattach the standby adhesive tape to the supply adhesive tape.

  According to this configuration, since the rear end portion of the supply adhesive tape and the leading end portion of the standby adhesive tape are bonded together in the tape rejoining unit, the first supply of the adhesive tape to the bonding apparatus is not stopped. It is possible to reconnect the tape winding and the second tape winding. Thereby, it is possible to switch the tape winding from which the supplied adhesive tape is pulled out without stopping the sticking device. Therefore, the tact time of the work of attaching the tape is reduced, and the cost of the product can be reduced. In addition, it is possible to automatically reconnect the leading end of the standby adhesive tape to the rear end of the supply adhesive tape.

  In the above configuration, the tape rejoining unit is disposed between the first tape storage unit and the second tape storage unit in the alignment direction of the first tape storage unit and the second tape storage unit. With this configuration, it is possible to efficiently draw out both the adhesive tape pulled out of the first tape roll and the adhesive tape pulled out of the second tape roll.

  In the above configuration, the central axes of the tape winding bodies accommodated in the first tape accommodation portion and the second tape accommodation portion are arranged in parallel and vertically. By configuring in this manner, the degree of freedom in the arrangement of the tape supply device is increased. This makes it easy to change the layout of the sticking device and the tape supply device, and the entire device including the sticking device and the tape supply device can be made compact.

  In the above configuration, the first tape storage unit and the second tape storage unit further include a tape pressing unit that adjusts the pulling-out position of the adhesive tape on the outer periphery of the stored tape winding body, and the tape pressing unit is A pressure roller in contact with the outer periphery of the tape winding, around which a non-adhesive surface of the adhesive tape is wound, and a roller support which supports the pressure roller rotatably and movably in a central axial direction of the tape winding And the pressure-sensitive adhesive tape pulled out from the tape winding body is bent by the pressure roller, and the pressure roller is pressed against the outer peripheral surface of the tape winding body by the tension of the pressure-sensitive adhesive tape. By doing so, when the adhesive tape is peeled off from the tape winding, it is hard to occur that the adhesive tape is peeled off more than a certain amount at a stretch. In this way, it is possible to suppress the problem that the adhesive tape is not easily loosened in the tape supply device, and the adhesive tape can not be supplied because the adhesive tape sticks to the inner surface or component members of the device or the adhesive surfaces stick to each other.

  In the above configuration, the tape rejoining portion opposes the supply adhesive tape with the first holding plate portion capable of holding the adhesive tape drawn from the first tape roll as the standby adhesive tape; And a second holding plate portion capable of holding, as the standby pressure-sensitive adhesive tape, the adhesive tape drawn from the second tape winding body, and the first holding plate portion and the second holding plate portion have surfaces facing each other The supply adhesive tape and the standby adhesive tape are pasted together by bringing the surfaces facing each other into contact with each other. By doing this, it is possible to easily attach the supply adhesive tape and the standby adhesive tape.

  In the above configuration, of the first holding plate portion and the second holding plate portion, at least the holding plate portion holding the non-adhesive surface of the standby pressure-sensitive adhesive tape sucks air and sucks the standby pressure-sensitive adhesive tape. It has a suction unit. In this way, even the non-adhesive surface of the standby adhesive tape can be easily held.

  In the above configuration, the tape rejoining unit includes a tape cutting unit capable of individually cutting the adhesive tape drawn from the first tape roll and the adhesive tape drawn from the second tape roll, In the tape reconnection operation, the supply adhesive tape and the standby adhesive tape are attached to each other by bringing the opposing surfaces of the first holding plate portion and the second holding plate portion into contact with each other, and then the tape cutting portion The supply adhesive tape is cut. By doing this, it is possible to reconnect the standby adhesive tape to the supply adhesive tape without lowering the tension of the supply adhesive tape.

  In the above configuration, the tape cutting unit includes a cutting table for holding the supplied adhesive tape, and a cutting blade that is movable in a direction intersecting the pulling direction of the supplied adhesive tape. The cutting table is provided with a first holding portion for holding the surface of the supply adhesive tape opposite to the cutting blade portion, and a gap downstream of the first holding portion in the pulling direction of the supply adhesive tape. And a second holding unit arranged to hold the same surface as the first holding unit of the supply adhesive tape. A non-adhesive treatment is applied to at least the surface of the cutting table on which the adhesive surface of the supply adhesive tape contacts, and the cutting blade of the cutting blade moves into the gap to move the supply adhesive tape. It is cut off. With such a configuration, since tension can be generated in the supplied adhesive tape at the time of cutting, the supplied adhesive tape can be reliably cut. Moreover, the non-adhesive process is performed to the surface which an adhesive surface contacts, and the supply adhesive tape after a cutting | disconnection tends to peel from a tape cutting part. Thereby, even after the supply adhesive tape is switched, the supply of the supply adhesive tape is performed smoothly.

  In the above configuration, the tape delivery unit winds the supply adhesive tape having the same length as the delivery adhesive tape is fed every time the delivery adhesive tape is fed by a predetermined length. Pull out from the wrapped tape. By doing this, the tape feeding unit can shift the timing of tape feeding and the timing of tape pulling out. By shifting these timings, the standby adhesive tape can be easily reconnected to the supply adhesive tape. In addition, the tension of the adhesive tape delivered from the tape delivery unit becomes constant or substantially constant, and it is possible to efficiently perform the tape affixing operation of the affixing device.

  In the above configuration, in the tape feeding unit, a supply roller around which the adhesive surface of the supply adhesive tape is wound, and a part closer to the tape joining unit than the supply roller for the supply adhesive tape is wound And a drawing roller reciprocally movable along a predetermined path, wherein the supply roller is rotatable only in the direction of supplying the supply adhesive tape, and the drawing roller is configured to supply the supply adhesive tape. By being pulled out, it is moved to one side of the path, and by being moved to the other side of the path, the supplied adhesive tape is pulled out from the tape winding on which the supplied adhesive tape is wound, and the tape feeding portion The movable portion includes a movable portion moving the drawing roller moved to one side of the path to the other side of the path.

 According to the present invention, it is possible to provide a tape supply device which does not require complicated structure and control, and which can replace the tape winding on which the adhesive tape is wound without stopping the operation of the sticking device.

The lower tape transport path 200 b transports the adhesive tape supplied from the tape supply device 3 to the lower tape unit 20 b.

  The upper tape transport path 200a includes a plurality of guide rollers 201 on which the adhesive tape is wound. The guide roller 201 guides the adhesive tape Tp conveyed from the tape supply device 3 to the upper tape unit 20 a. The guide roller 201 is rotatable, and the adhesive tape Tp is stretched so that the adhesive tape Tp does not sag or overtension. Further, the adhesive tape Tp is bent in the transport direction by the guide roller 201.

  The lower tape transport path 200b includes a plurality of guide rollers 202 on which an adhesive tape is wound. The guide roller 202 guides the adhesive tape Tp conveyed from the tape supply device 3 (3b) to the lower tape unit 20b. The guide roller 202 is rotatable, and the adhesive tape Tp is stretched so that the adhesive tape Tp does not sag or overtension. Further, the adhesive tape Tp is bent in the transport direction by the guide roller 202. The upper tape transport path 200a and the lower tape transport path 200b are different because the transport path of the adhesive tape Tp is different although the number of guide rollers is different.

  The upper tape unit 20a and the lower tape unit 20b respectively stick the tip of the adhesive tape Tp to the upper end and the lower end of the front surface in the transport direction of the box Bx. Then, when the box Bx is transported, the adhesive tape Tp is pulled by the box Bx and pulled out from the tape supply device 3. The adhesive tape Tp is supplied from the tape supply device 3, and the details of the supply of the adhesive tape Tp will be described later.

  And with conveyance of box Bx, upper side tape unit 20a sticks adhesive tape Tp to a butt part of flap Fp of the upper surface of box Bx. In the lower tape unit 20b, the adhesive tape Tp is attached to the butting portion of a flap (not shown) on the lower surface of the box Bx. Then, when the box Bx moves to a predetermined position, the adhesive tape Tp is cut by a cutter (not shown) provided in the upper tape unit 20a and the lower tape unit 20b. The cut end portion of the adhesive tape Tp attached to the box Bx is pressed against the rear side in the transport direction by the upper tape unit 20a and the lower tape unit 20b to be stuck. As described above, the tape application device 2 applies the adhesive tape Tp to the butting portions of the flaps on the upper surface and the lower surface of the box Bx being transported, and the sealing operation is performed.

<Tape feeding device>
As shown in FIG. 1, the tape supply device 3 includes a first tape supply device 3a that supplies the adhesive tape Tp to the upper tape unit 20a and a second tape supply device 3b that supplies the adhesive tape Tp to the lower tape unit 20b. And The first tape supply device 3a and the second tape supply device 3b have the same configuration except that the transport destination of the drawn adhesive tape Tp is different. Therefore, in the following description, the first tape supply device 3a and the second tape supply device 3b will be described as the tape supply device 3 as a representative. Moreover, in each drawing used by the following description, adhesive tape Tp inside the tape supply apparatus 3 shall be arrange | positioned perpendicularly | vertically with respect to a paper surface. In addition, the adhesive tape Tp is assumed to be transported along the paper surface.

  Next, the details of the tape supply device 3 will be described with reference to the new drawings. FIG. 2 is a front view of the example of the tape supply device according to the present invention in a state in which the first door is opened. FIG. 3 is a view showing a schematic configuration of the tape supply apparatus shown in FIG. FIG. 4 is a block diagram of a tape supply apparatus according to the present invention.

  In the following description, in the tape supply device 3, the adhesive tape supplied to the tape sticking device 2 is referred to as a supplied adhesive tape Tps, and is indicated by a thick solid line in the drawing. Further, the adhesive tape which is pulled out of a tape winding other than the supplied adhesive tape and which stands by at the tape joining portion 33 is referred to as a standby adhesive tape Tpw, which is indicated by a thick solid line in the drawing. For example, in the tape supply device 3 shown in FIG. 3, the adhesive tape pulled out from the first tape roll Ra1 stored in the first tape storage unit 31 is the supplied adhesive tape Tps, and the second tape stored in the second tape. The adhesive tape pulled out of the tape roll Ra2 is the standby adhesive tape Tpw. The supply adhesive tape Tps and the standby adhesive tape Tpw are names for convenience of description and are substantially the same members. For this reason, the supply adhesive tape Tps and the standby adhesive tape Tpw may both be described as the adhesive tape Tp, unless otherwise required.

  As shown in FIGS. 1 and 2, the tape feeding device 3 includes a main body 300, a first door 301 for opening and closing the upper part of the main body 300, and a second door 302 for opening and closing the lower part of the main body 300. . The first door 301 is provided with a grip portion 303 (handle 303). The first door 301 is rotatably supported with respect to the main body 300 at an end opposite to the grip 303. The first door 301 is arranged to open and close the first tape storage unit 31. The second door 302 is provided with a grip 304 (handle 304). The second door 302 is rotatably supported with respect to the main body 300 at an end opposite to the grip 304. The second door 302 is disposed to open and close the second tape storage unit 34. That is, the tape supply device 3 opens and closes the first tape storage unit 31 with the first door 301 and opens and closes the second tape storage unit 32 with the second door 302. The first door 301 and the second door 302 can be opened and closed independently of each other.

  In the tape supply device 3, the tape roll is a consumable and needs to be replaced. The tape supply device 3 can individually open and close the first tape storage unit 31 and the second tape storage unit 32 at the time of tape replacement. Therefore, when replacing one tape winding of the first tape storage unit 31 and the second tape storage unit 32, it is not necessary to stop the other.

  As shown in FIG. 3, the tape supply device 3 includes a first tape storage unit 31, a second tape storage unit 32, a tape connection unit 33, and a tape delivery unit 4. The first tape storage unit 31, the second tape storage unit 32, and the tape connection unit 33 are stored inside the main body unit 300. Further, as shown in FIG. 4, the tape supply device 3 includes a control unit 35, an operation unit 36, and a notification unit 37.

  As shown in FIG. 3, in the tape supply device 3, the first tape storage unit 31 and the second tape storage unit 32 are arranged vertically. The first tape storage unit 31 stores a first tape roll Ra1 around which an adhesive tape Tp (here, referred to as a supplied adhesive tape Tps) supplied to the tape sticking device 2 is wound. The first tape storage unit 31 includes a first storage roller 311, a first remaining amount detection sensor 312, and a tape pressing unit 313.

  The first storage roller 311 is rotatable, and the first tape roll Ra1 is attached. The first accommodation roller 311 rotates together with the first tape roll Ra1 when the supplied adhesive tape Tp is delivered. The adhesive tape Tp from the first tape roll Ra1 is pulled out by the pulling operation of the tape feeding unit 4 described later.

  The first remaining amount detection sensor 312 is disposed in the vicinity of the first storage roller 311. The first remaining amount detection sensor 312 is an example of a remaining amount detection unit, and includes, for example, a light source that emits light to the first tape winding Ra1 and a light receiving element that detects light from the light source. The light source emits light to the first tape winding Ra1 from a predetermined position. The light receiving element is disposed at a position where the light from the light source is received when the remaining amount of the first tape roll Ra1 reaches a certain amount, for example, when the first tape roll Ra1 has no remaining tape. It is done. With such a configuration, the first remaining amount detection sensor 312 can detect that the remaining amount of the first tape roll Ra1 stored in the first tape storage portion 31 has run out. The light from the light source may be irradiated in the axial direction or in the tangential direction to the first tape roll Ra1 stored in the first tape storage portion 31. In any case, the remaining amount of the first tape roll Ra1 can be detected by adjusting the positions of the light source and the light receiving element. Furthermore, as the first remaining amount detection sensor 312, the rotation angle of the roller support portion 314 (described later) of the tape holding portion 313 and / or the position of the holding roller 315 are detected to detect the remaining amount of the first tape roll Ra1. It may be a sensor.

  The first remaining amount detection sensor 312 is connected to the control unit 35 (see FIG. 4). Then, when it is detected that the remaining amount of the first tape roll Ra1 stored in the first tape storage unit 31 is exhausted, the first remaining amount detection sensor 312 transmits the information to the control unit 35. The control unit 35 may calculate the remaining length of the supplied adhesive tape Tps by calculation based on the information from the first remaining amount detection sensor 312. By doing this, the leading end of the standby adhesive tape Tpw can be stuck in the vicinity of the rear end of the supply adhesive tape Tps as much as possible, and the discarded adhesive tape Tp can be reduced as much as possible. The first remaining amount detection sensor 312 detects the remaining amount of the first tape roll Ra1 stored in the first tape storage portion 31. However, it is not limited to this. For example, the presence or absence of the adhesive tape Tp disposed in the vicinity of the tape splicing unit 33 may be directly detected. By doing so, the first remaining amount detection sensor can accurately detect the rear end of the supplied adhesive tape Tps.

  In the first tape roll Ra1 stored in the first tape storage unit 31, the adhesive tape Tp is pulled by the tape feeding unit 4, and the adhesive tape wound around the outermost periphery is pulled off, and Be sent out. Here, the adhesive tape and the tape winding will be described. Here, the adhesive tape Tp is a tape (OPP tape) whose base material is OPP (polypropylene), and the adhesive strength of the adhesive surface is stronger than that of a paper tape (so-called kraft tape). And when this adhesive tape Tp peels off from a tape winding body, it is often peeled at once by a certain length (indefinite length).

  When the adhesive tape is pulled by the pulling-out operation of the tape feeding unit 4 and the adhesive tape Tp of a certain length is pulled from the first tape roll Ra1 stored in the first tape storage unit 31, the tape is supplied This causes the adhesive tape Tp to be slackened inside the device 3. Therefore, the first tape storage portion 31 suppresses the tape holding portion 313 from peeling off the adhesive tape Tp at a stretch from the first tape roll Ra1. Here, the tape pressing portion 313 will be described.

  The tape pressing portion 313 includes a roller support portion 314, a pressing roller 315, a rotating shaft 316, and a tape bending roller 317. The roller support portion 314 is an elongated member, and is configured such that the adhesive tape Tp can pass therethrough. The roller support portion 314 has, for example, a configuration in which a pair of elongated plate members are supported facing each other. A pressing roller 315 is rotatably supported at one end of the roller support 314. In addition, the other end of the roller support 314 is rotatably supported by the rotation shaft 316. The bending roller 317 is rotatably attached to the rotation shaft 316.

  The roller support portion 314 is rotatably supported by the rotation shaft 316, and when the roller support portion 314 rotates around the rotation shaft 316, the pressure roller 315 supported rotatably by the roller support portion 314 is , Approaches or separates from the central axis of the first tape winding Ra1. Then, the pressure-sensitive adhesive tape Tp is wound around the pressure roller 315 such that the non-adhesive surface of the pressure-sensitive adhesive tape Tp wound around the first tape winding Ra1 contacts.

  Then, the adhesive tape Tp wound around the pressing roller 315 crosses the roller support portion 314, and is wound around the bending roller 317. The bending roller 317 is in contact with the adhesive surface of the adhesive tape Tp. The adhesive tape Tp wound around the bending roller 317 is disposed in the tape joining section 33. Here, the adhesive tape Tp from the first tape roll Ra1 is the supplied adhesive tape Tps, and the supplied adhesive tape Tps passes through the tape joining unit 33 and is sent to the tape delivery unit 4.

  The adhesive tape Tp from the first tape roll Ra 1 is bent by the press roller 315 by being wound around the press roller 315 and the bending roller 317. Then, in this state, the adhesive tape Tp is pulled in the delivery direction. When the adhesive tape Tp is pulled, that is, tension in the transport direction acts on the adhesive tape Tp, the adhesive tape Tp biases the pressure roller 315 toward the central axis of the pressure roller 315. Then, when the pressing roller 315 is in contact with the outer peripheral surface of the first tape roll Ra1, the point at which the adhesive tape Tp is pulled out from the first tape roll Ra1 is that the first tape roll Ra1 and the pressing roller 315 It is the point in contact. Then, if the central angle of the area of the pressure roller 315 around which the adhesive tape Tp is wound is greater than 90 degrees, the tension of the adhesive tape Tp pushes the pressure roller 315 to the contact point with the first tape roll Ra1. Includes force components. That is, by the tension of the adhesive tape Tp, a force in the direction approaching the central axis of the first tape roll Ra1 is applied to the pressing roller 315. Therefore, the central angle of the area of the pressing roller 315 around which the adhesive tape Tp is wound is preferably larger than 90 degrees, and more preferably around 180 degrees or more.

  In this manner, by winding the adhesive tape Tp around the tape pressing portion 313 and arranging the adhesive tape Tp, the tension of the adhesive tape Tp when the adhesive tape Tp is pulled in the delivery direction causes the pressing roller 315 to be the outer periphery of the first tape roll Ra1. It is pressed against the surface. As a result, when the adhesive tape Tp is peeled from the first tape roll Ra1, the length of the adhesive tape Tp can not be peeled off at a stretch at a certain distance, or it becomes difficult to peel at a stretch. From this, in the inside of the tape supply device 3, the adhesive tape Tp is difficult to be loosened, and the adhesive tape Tp is loosened and stuck to the inside of the tape supply device 3, or the adhesive surfaces of the adhesive tape Tp stick together. It can be suppressed.

  Further, as shown in FIG. 12 described later, the pressing roller 315 of the tape pressing portion 313 is driven by the core of the first tape roll Ra1, ie, the first storage roller 311, by the tension of the wound supply adhesive tape Tps. It is pressed. Further, in the tape pressing unit 313, the pressing roller 315 is pressed against the outer peripheral surface of the first tape roll Ra1 by the tension of the adhesive tape Tp. Therefore, when the remaining amount of the adhesive tape Tp is exhausted, the pressure applied to the first tape roll Ra1 is released. At this time, it is preferable that the pressing roller 315 and the roller support portion 314 be formed so as to return to the initial position which does not get in the way when the new first tape roll Ra1 is stored in the first tape storage portion 31. As such a configuration, a biasing member that biases the roller support 314 may be provided, or the configuration may be such as returning to the original position by its own weight.

  Then, the adhesive tape Tp wound around the pressing roller 315 crosses the roller support portion 314, and is wound around the bending roller 317. The bending roller 317 is in contact with the adhesive surface of the adhesive tape Tp. The adhesive tape Tp wound around the bending roller 317 is sent to the tape joining unit 33. Here, the adhesive tape Tp from the first tape roll Ra1 is the supplied adhesive tape Tps, and the supplied adhesive tape Tps passes through the tape joining unit 33 and is sent to the tape delivery unit 4.

  In the tape pressing portion 313, the pressing roller 315 contacts the non-adhesive surface of the adhesive tape Tp, and the bending roller 317 contacts the adhesive surface of the adhesive tape Tp. Therefore, the material and / or the shape of the surface may be different between the pressing roller 315 and the bending roller 317. For example, the pressing roller 315 in contact with the non-adhesive surface of the adhesive tape Tp is made of a material and / or a shape having high friction with the non-adhesive surface of the adhesive tape Tp. The bending roller 317 in contact with the adhesive surface of the adhesive tape Tp is made of a material and / or shape from which the adhesive surface of the adhesive tape Tp can be easily peeled off. Thus, conveyance of the adhesive tape Tp in the inside of the tape supply apparatus 3 becomes smooth by separating the material and / or shape of a roller. In addition, since the adhesive surface is easily peeled off from the roller in contact with the adhesive surface of the adhesive tape Tp, the adhesive can be prevented from remaining on the roller, and the adhesive force of the adhesive tape Tp sent to the tape application device 2 Can be controlled. As a shape which an adhesive tape does not stick easily, the method of providing a slit in the surface of a roller, for example, and making a contact area small can be mentioned.

  In addition to the pressing roller 315 and the bending roller 317, the tape supply device 3 includes a roller around which the adhesive tape Tp is wound. Also in such a roller, a material and / or a shape having a high frictional force with the non-adhesive surface is adopted for the roller in contact with the non-adhesive surface unless otherwise noted. In this case, a material and / or a shape from which the adhesive surface is easily peeled off is adopted. The same applies to the transport rollers 201 and 202 of the tape sticking apparatus 2.

  The second tape storage unit 32 is disposed below the first tape storage unit 31. The second tape storage unit 32 includes a second storage roller 321, a second remaining amount detection sensor 322, and a tape pressing unit 323. The second accommodation roller 321 has the same configuration as the first accommodation roller 311, and the second remaining amount detection sensor 322 has the same configuration as the first remaining amount detection sensor 312, so the detailed description will be omitted. Further, the tape pressing portion 323 is substantially the same in configuration as the tape pressing portion 313 although the form of arrangement of the adhesive tape Tp is different. Therefore, the detailed description of the tape pressing portion 323 is omitted. The roller support portion 324, the press roller 325, the rotary shaft 326 and the tape bending roller 327 of the tape press portion 323 are respectively the roller support portion 314 of the tape press portion 313, the press roller 315, the rotary shaft 316 and the tape bending roller 317. It is substantially the same configuration as

  That is, in the second tape storage unit 32, the second tape roll Ra2 in which the adhesive tape Tp is wound is disposed. The central axes of the second accommodation roller 321 of the second tape accommodation unit 32 and the first accommodation roller 311 of the first tape accommodation unit 31 are parallel, that is, the central axes are with respect to the plane of the drawing shown in FIG. Arranged vertically. The rollers disposed inside the tape supply device 3 are disposed so that the central axis is perpendicular to the drawing shown in FIG. By arranging in this manner, it is possible to make the adhesive tape Tp wound around the roller perpendicular to the drawing shown in FIG.

  The adhesive tape Tp drawn out from the first tape roll Ra1 stored in the first tape storage portion 31 and the adhesive tape Tp drawn out from the second tape roll Ra2 stored in the second tape storage portion 32 respectively It is sent to the tape reconnection unit 33. As shown in FIG. 3, the tape joining unit 33 is disposed at the center of the first tape storage unit 31 and the second tape storage unit 32 in the arrangement direction of the first tape storage unit 31 and the second tape storage unit 32. It is done. The tape rejoining unit 33 may not be at the center of the first tape storage unit 31 and the second tape storage unit 32, and may be shifted from the center to one side. In addition, it does not have to be between the first tape storage section 31 and the second tape storage section 32, and one of the first tape storage section 31 and the second tape storage section 32 is located farther from the other than the other. It may be provided. However, in order to simplify the arrangement route of the adhesive tape Tp from the first tape storage unit 31 and the second tape storage unit 32, the tape joining unit 33 includes the first tape storage unit 31 and the second tape storage unit 32. It is preferable to arrange between them.

<Tape reattaching unit>
The tape reconnection unit 33 includes a tape cutting unit 34. In addition, the tape reconnection unit 33 includes a first pull-in roller 331, a second pull-in roller 332, a first holding plate portion 333, a first holding plate drive portion 334, a second holding plate portion 335, and a second And a holding plate driving unit 336.

  The first pull-in roller 331 is wound with the adhesive tape Tp drawn from the first tape roll Ra1 stored in the first tape storage portion 31. The first pull-in roller 331 is in contact with the non-adhesive surface of the adhesive tape Tp. In the second pull-in roller 332, the adhesive tape Tp drawn from the second tape roll Ra2 stored in the second tape storage portion 32 is wound. The second pull-in roller 332 is in contact with the adhesive surface of the adhesive tape Tp.

  The first pull-in roller 331 and the second pull-in roller 332 merely bend the direction of the adhesive tape Tp, but the invention is not limited thereto. For example, even when the remaining amount of the supply pressure-sensitive adhesive tape of the tape winding is exhausted, the supply pressure-sensitive adhesive tape passing through the tape connecting section 33 may be maintained in a state where a certain degree of tension is applied. As such a configuration, for example, a roller provided in contact with each of the first pull-in roller 331 and the second pull-in roller 332 can be provided to hold and hold the supplied adhesive tape Tps. Moreover, it is possible to employ | adopt widely the structure which can provide tension to an adhesive tape also except these.

  The first holding plate portion 333 and the second holding plate portion 335 are both plate-shaped members. The lower surface of the first holding plate portion 333 and the upper surface of the second holding plate portion 335 are arranged to face each other. The lower surface of the first holding plate portion 333 and the upper surface of the second holding plate portion 335 are respectively holding surfaces. The first holding plate 333 and the second holding plate 335 hold the leading end of the standby adhesive tape Tpw in the conveyance direction on the holding surface. In the tape supply device 3 shown in FIG. 3, the adhesive tape Tp pulled out from the second tape roll Ra2 is the standby adhesive tape Tpw. Therefore, the leading end of the standby adhesive tape Tpw wound around the second pull-in roller 332 is held by the holding surface of the second holding plate portion 335.

  The adhesive surface of the standby adhesive tape Tp is attached to the second holding plate portion 335. Therefore, at least a portion of the second holding plate portion 335 in contact with the adhesive tape Tp, the adhesive surface is difficult to stick, that is, it is formed of a material such as silicone rubber etc. It is done. In the same manner as the second holding plate portion 335, at least a portion of the first holding plate portion 333 in contact with the pressure-sensitive adhesive tape Tp is formed of a material that does not easily stick the adhesive surface of the pressure-sensitive adhesive tape Tp such as silicone rubber. Good. Moreover, the adhesive force of adhesive tape Tp is decided by the area to stick. Therefore, the adhesion may be adjusted by providing asperities (grooves) on the surface where the adhesive tape Tp comes in contact to reduce the area to be stuck.

  The adhesive tape Tp pulled out from the first tape roll Ra1, that is, the supplied adhesive tape Tps, and the adhesive tape Tp pulled out from the second tape roll Ra2, that is, the standby adhesive tape Tpw both have adhesive surfaces. It is downward. Therefore, when using the adhesive tape Tp drawn from the second tape roll Ra2 as the standby adhesive tape Tpw, holding the adhesive surface of the standby adhesive tape Tpw on the holding surface of the second holding plate portion 335 can be held. It is possible. On the other hand, as shown in FIG. 15 described later, the adhesive tape Tp drawn from the first tape roll Ra1 may be the standby adhesive tape Tpw.

  In this case, since the non-adhesive surface of the standby adhesive tape Tpw faces the holding surface of the first holding plate portion 333, it is difficult to attach the standby adhesive tape Tpw to the first holding plate portion 333. In preparation for such a case, at least the first holding plate portion 333, that is, the holding plate portion that holds the non-adhesive surface of the standby adhesive tape Tpw, sucks air from the holding surface to obtain the standby adhesive tape Tpw. You may provide the adsorption | suction part which hold | maintains. The suction unit may be provided on both the first holding plate 333 and the second holding plate 335.

  In addition, although it is set as the structure which attracts | sucks an adhesive tape by attracting | sucking air as an adsorption | suction part, it is not limited to this. For example, a configuration that can reliably hold the tip of the standby adhesive tape Tpw can be widely adopted, such as one utilizing static electricity, one coated with an adhesive having a slightly lower adhesive strength than the adhesive surface, and the like.

  The first holding plate drive unit 334 is attached to the first holding plate unit 333. The first holding plate driving unit 334 is an actuator that moves the first holding plate unit 333 up and down. The first holding plate drive unit 334 may use, for example, pneumatic pressure as in a piston / cylinder, or may be electrically driven by providing a solenoid or the like. It is possible to widely adopt a configuration in which the first holding plate portion 333 can be operated reliably. The first holding plate driving unit 334 is connected to the control unit 35 (see FIG. 4). The first holding plate drive unit 334 operates in accordance with an instruction of the control unit 35.

  The second holding plate drive portion 336 is attached to the second holding plate portion 335. The second holding plate driving unit 336 is an actuator for moving the second holding plate portion 335 up and down. The second holding plate drive unit 336 may use, for example, pneumatic pressure as in a piston / cylinder, or may be electrically driven by providing a solenoid or the like. It is possible to widely adopt a configuration in which the second holding plate portion 335 can be operated reliably. The second holding plate driving unit 336 is connected to the control unit 35 (see FIG. 4). The second holding plate driving unit 336 operates in accordance with an instruction of the control unit 35.

  Then, the first holding plate driving unit 334 is driven to move the first holding plate portion 333 downward, and the second holding plate driving unit 336 is driven to move the second holding plate portion 335 upward. The holding surfaces of the first holding plate portion 333 and the second holding plate portion 335 come in contact with each other. Thus, the supplied adhesive tape Tps passing between the first holding plate 333 and the second holding plate 335 and the leading end of the standby adhesive tape Tpw held by the first holding plate 333 or the second holding plate 335 Is bonded. Although the details will be described later, the tape rejoining unit 33 supplies the standby adhesive tape Tpw by laminating the supplied adhesive tape Tps and the standby adhesive tape Tpw and then cutting the supplied adhesive tape Tps at the tape cutting unit 34. A tape changing operation for changing the adhesive tape Tps is performed. In addition, in this embodiment, although it is set as the structure which both the 1st holding board part 333 and the 2nd holding board part 335 move, you may be the structure which one approachs-separates with respect to the other.

<Tape cutting section>
Here, the details of the tape cutting unit 34 will be described with reference to the new drawings. FIG. 5 is an enlarged view showing a state in which the supplied adhesive tape disposed on the upper side of the cutting table in the tape cutting section is cut. Moreover, FIG. 6 is an enlarged view which shows the state which cut | disconnects the supply adhesive tape arrange | positioned under the cutting stand in the tape cutting part. The tape cutting unit 34 sticks the waiting adhesive tape Tpw to the supplied adhesive tape Tps, and then cuts the supplied adhesive tape Tps. In FIG. 5, the adhesive tape Tp drawn from the first tape roll Ra1 is used as the supplied adhesive tape Tps.

  As shown in FIG. 5, the tape cutting unit 34 includes a cutting stand 340, a first cutter 341, and a second cutter 342. The tape cutting unit 34 holds the supplied adhesive tape Tps when cutting the supplied adhesive tape Tps. As shown in FIG. 5, the cutting table 340 includes a first holding portion 343 and a second holding portion 344 which are arranged with a gap on the upstream side and the downstream side in the supply direction of the supply adhesive tape Tps. The first holding unit 343 is disposed downstream of the second holding unit 344 in the supply direction of the supply adhesive tape Tps.

  The first cutter 341 is disposed above the cutting table 340. In the first cutter 341, a cutting blade portion 345 extending with respect to the cutting stand 340 is accommodated. The cutting blade portion 345 extends from the first cutter 341 toward the gap between the first holding portion 343 and the second holding portion 344 of the cutting stand 340. Then, the cutting blade 345 of the first cutter 341 is inserted between the first holding portion 343 and the second holding portion 344. When the cutting edge of the cutting blade 345 enters between the first holding portion 343 and the second holding portion 344, the supply adhesive tape Tps is cut by the cutting edge.

  For example, when the cutting blade 345 moves to the gap between the first holding portion 343 and the second holding portion 344, the supplied adhesive tape Tps is pushed toward the cutting table 340 by the cutting edge. At this time, the downstream side of the supply adhesive tape Tps in the supply direction with respect to the cutting edge of the cutting blade portion 345 of the supply adhesive tape Tps contacts the first holding portion 343, and the upstream side contacts the second holding portion 344.

  In the case where the adhesive tape Tp drawn from the first tape roll Ra1 is the supplied adhesive tape Tps, the adhesive surface is the lower side, that is, the cutting table 340 side. Therefore, the supply adhesive tape Tps is pressed by the cutting blade 345 and sticks to both the first holding portion 343 and the second holding portion 344. When the adhesive surface of the supply adhesive tape Tps is attached to the first holding unit 343 and the second holding unit 344, the supply adhesive tape Tps is fixed and tension is increased when it is pressed by the cutting blade 345. As a result, even when the tension of the portion of the supply adhesive tape Tps facing the cutting table 340 is low, the supply adhesive tape Tps can be cut by the cutting edge of the cutting blade 345.

  In the tape cutting unit 34, the supplied adhesive tape Tps is attached to the first holding unit 343 and the second holding unit 344 in order to obtain tension that can be cut by the cutting blade 345. On the other hand, when the supplied adhesive tape Tps is firmly attached to the first holding portion 343 and the second holding portion 344, the adhesive tape Tp is difficult to be pulled out, and the supply operation of the adhesive tape may be unstable. is there. In addition, when attaching a new tape roll, it is difficult to remove the adhesive tape Tp stuck to the first holding portion 343 and the workability of the replacement work of the tape roll becomes worse. Therefore, in the cutting stand 340, non-adhesive processing may be applied to a portion in contact with the adhesive surface of the supplied adhesive tape Tps.

  The non-adhesive treatment may include, for example, adron treatment, but is not limited thereto. For example, the adhesion may be adjusted by forming an infinite number of grooves in the surface of the first holding portion 343 and the second holding portion 344 in contact with the adhesive surface of the supplied adhesive tape Tp to reduce the contact area. . In addition, as a non-adhesive treatment, it adheres with an adhesive force that generates a tension that can be cut by pressing the supplied adhesive tape Tps with the blade edge of the cutting blade 345 and does not leave adhesive when the adhesive surface is peeled off. Processing is preferable. In addition, as a surface where non-adhesive treatment is performed, the surface where supply adhesive tape Tps opposes can be mentioned. Also, mention may be made of the side where the supplied adhesive tape Tps may stick during or after cutting, for example, the downstream side of the supply direction of the supplied adhesive tape Tps of the first holding portion 343, the inner surface of the gap, etc. it can.

  Further, as shown in FIG. 6, the second cutter 342 is disposed below the cutting table 340. Then, the cutting blade portion 346 extends from the second cutter 342 toward the cutting table 340. The cutting blade 346 moves to insert the blade towards the gap between the first holding portion 343 and the second holding portion 344 as in the case of the cutting blade 345. When cutting the adhesive tape Tp drawn from the second tape roll Ra2, the cutting edge of the cutting blade 346 contacts the adhesive surface of the supply adhesive tape Tps. That is, the supply adhesive tape Tps adheres to the cutting edge of the cutting blade 346.

  Further, the supply roller 45 of the tape delivery unit 4 described later is configured to rotate only in the supply direction. Therefore, when the cutting edge of the cutting blade portion 346 to which the adhesive surface of the supply adhesive tape Tps is attached moves into the gap between the first holding portion 343 and the second holding portion 344, the supply roller 45 and the cutting edge of the cutting blade portion 346 The tension on the supply adhesive tape Tps during the raise. Therefore, even when the non-adhesive surface of the supplied adhesive tape Tps contacts the first holding unit 343 and the second holding unit 344, the tension of the supplied adhesive tape Tps is increased by the movement of the cutting blade 346. It is cut off. Since the cutting edge of the cutting blade 346 has a very small area, the adhesive surface of the supply adhesive tape Tps is narrow. Therefore, when the cutting blade 346 returns to the original position, the supplied adhesive tape Tps attached to the cutting edge is easily peeled off. As a result, even when the supply adhesive tape Tps is cut, the supply operation is stably performed.

  Further, the surface of the cutting stand 340 opposite to the second cutter 342, that is, the lower surface is in contact with the non-adhesive surface of the supply adhesive tape Tps. Therefore, the non-adhesive process may be performed and the non-adhesive process may not be performed. In the cutting stand 340 in the present embodiment, the lower surfaces of the first holding portion 343 and the second holding portion 344 are also subjected to non-adhesive processing.

  In the present embodiment, as the cutting table 340, the first holding unit 343 and the second holding unit 344 are disposed with a gap in the supply direction of the supply adhesive tape Tps, but the invention is not limited thereto. For example, as in the tape cutting unit 34B shown in FIG. 7, the cutting stand 347 is recessed on the side opposite to the first cutter 341 and the second cutter 342 on the side facing the first cutter 341 and the second cutter 342 respectively. It may have a configuration provided with the concave portions 348 and 349.

<Tape delivery section>
The tape delivery unit 4 will be described. In the tape feeding unit 4, the supplied adhesive tape Tps which has passed through the tape joining unit 33 is disposed. As shown in FIG. 3 and the like, the tape feeding unit 4 includes a drawing roller 41, position fixing rollers 42, 43 and 44, a supply roller 45, a drawing roller 46, a roller driving unit 47, and a roller position detection sensor 48. (See FIG. 4).

  In the tape feeding unit 4, the supplied adhesive tape Tps drawn from the tape joining unit 3 is wound around the drawing roller 41. Then, the supply adhesive tape Tps is wound around the lower side of the position fixing roller 43 disposed on the upper side and the lower side of the position fixing roller 42 disposed on the upper side. Furthermore, the supply adhesive tape Tps is wound on the upper side of the pull-out roller 46 disposed in the lateral direction of the position fixing roller 43 and under the position fixing roller 44 disposed in line with the position fixing roller 43. It is wound. Finally, the supply adhesive tape Tps is wound on the upper side of the supply roller 45 disposed on the upper side, and is supplied to the tape application device 2.

  The drawing-in roller 41 and the position fixing rollers 42, 43 and 44 are rollers which can rotate at a predetermined (fixed position). As shown in FIG. 3, by feeding the supply adhesive tape Tps up and down, the supply adhesive tape Tps is supported so as not to be slackened.

  A roller drive unit 47 is disposed at a laterally intermediate portion between the position fixing roller 43 and the position fixing roller 44. The roller drive unit 47 rotatably supports the drawing roller 46. The roller drive unit 47 moves the drawing-out roller 46 in the direction (upward direction) intersecting the arrangement direction of the position fixing roller 43 and the position fixing roller 44. As shown in FIG. 4, the roller drive unit 47 is connected to the control unit 35, and operates according to an instruction of the control unit 35. The roller drive unit 47 may be, for example, one that linearly moves using air pressure such as a piston / cylinder, or one that linearly moves by electric and magnetic forces. Although the details will be described later, the roller drive unit 47 moves the drawing roller 46 away from the position fixing rollers 43 and 44. Although the drawing roller 46 is assumed to move in the vertical direction, it is not limited thereto. If it is a direction which approaches and separates from the position fixing rollers 43 and 44, no particular direction is required.

  The supply roller 45 is disposed in line with the position fixing roller 42 in the lateral direction. The supply roller 45 is disposed at the most downstream side in the supply direction of the supply adhesive tape Tps in the tape delivery unit 4. The supply roller 45 internally includes a mechanism such as a one-way clutch, a ratchet, etc., which limits the rotational direction to one direction. The rotation direction of the supply roller 45 is the direction in which the supply adhesive tape Tps is supplied. The supply roller 45 is in contact with the adhesive surface of the wound supply adhesive tape Tps. Thus, the supply adhesive tape Tps and the supply roller 45 are relatively unlikely to slip.

  The roller position detection sensor 48 is a detection unit that detects the position of the pull-in roller 46. The roller position detection sensor 48 accurately detects the position of the drawing-in roller 46, such as one using light (infrared light, ultraviolet light, etc.), one using sound waves, one having physical switches such as limit switches, etc. A wide range of possible configurations can be adopted. In the tape feeding unit 4 of the present embodiment, an optical position sensor including a light source and a light receiving element is employed. As shown in FIG. 4, the roller position detection sensor 48 is connected to the control unit 35. The control unit 35 accurately grasps the position of the drawing roller 46 by the information from the roller position detection sensor 48.

  Here, the operation of the tape feeding unit 4 will be described with reference to a new drawing. FIG. 8 is a schematic view of the tape feeding portion before feeding the adhesive tape to the tape sticking apparatus. FIG. 9 is a schematic view of a tape feeding unit in a state where an adhesive tape of a fixed length is supplied to the tape sticking apparatus. FIG. 10 is a schematic view of a tape feeding portion when pulling out the adhesive tape from the tape winding.

  As shown in FIG. 8, when the supplied adhesive tape Tps is not supplied from the tape feeding unit 4, the drawing-out roller 46 is at the upper end position (this position is referred to as a first position P1).

  When the box Bx is sealed with the tape sticking apparatus 2, the adhesive tape Tp is pulled in the pull-out direction, that is, in the direction indicated by the arrow Ar1 in FIG. 8 by the conveyance of the box Bx. At this time, the pull-out roller 46 is pushed downward by the tension of the adhesive tape Tp and is moved downward (see FIG. 9). When the pressure-sensitive adhesive tape Tp is pulled, the pull-out roller 46 moves downward, so that movement of the box Bx makes it difficult to pull out the tape from the tape winding. The roller drive unit 47 urges the drawing roller 46 upward such that the downward movement of the drawing roller 46 is not disturbed, in other words, the supplied adhesive tape Tps is not slackened.

  The tape feeding unit 4 continuously passes the supplied adhesive tape Tps wound around the position fixing roller 44 from the position fixing roller 43 of the tape feeding unit 4 through the drawing roller 46 to the outside (here, the tape sticking device 2) It can be supplied.

  As shown in FIG. 9, when the pullout roller 46 moves to the lower end position (this position is referred to as a second position P2), the roller position detection sensor 48 detects that the pullout roller 46 is at the second position P2. At this time, the control unit 35 sends a drive instruction to the roller drive unit 47, and causes the roller drive unit 47 to move the drawing roller 46 from the second position P2 to the first position P1. At this time, the drawing roller 45 has a mechanism that does not rotate in the direction opposite to the supply direction of the supply adhesive tape Tps, and the supply adhesive tape Tps does not slip relative to the drawing roller 46. As a result, when the pull-out roller 46 moves from the second position P2 to the first position P1, the adhesive tape Tp delivered from the tape delivery unit 4 to the tape application device 2 does not reversely flow back to the tape delivery unit 4. In addition, since the supply roller 45 does not rotate in the reverse direction, the tension of the adhesive tape Tp supplied to the outside of the tape feeding unit 4 does not rise or does not easily rise. Therefore, the supply adhesive tape Tps is pulled out from the tape winding body (the first tape winding Ra1 in FIG. 3) by moving the drawing roller 46 from the second position P2 to the first position P1 (see FIG. 10) . Therefore, an operation of driving the tape drive unit 47 to move the drawing roller 46 is referred to as a tape drawing operation.

  In the tape feeding unit 4, the roller driving unit 47 is driven each time the adhesive tape Tp having a length of the supplied adhesive tape Tps wound around the position fixing roller 44 from the position fixing roller 43 passes through the drawing roller 46. Let out and pull out the supplied adhesive tape Tps from the tape roll. Therefore, the length of the supply adhesive tape Tps wound around the position fixing roller 44 from the position fixing roller 43 through the drawing roller 46 is the length of the adhesive tape Tp necessary for sealing one box Bx. By setting the integral multiple (including one), it is possible to perform the tape pull-out operation between sealing operations of the box Bx. Thereby, it is possible to carry out the supply operation of the adhesive tape smoothly.

  Further, the length of the supplied adhesive tape Tps to be drawn out by the movement of the drawing roller 46 is set to be an integral multiple (including 1 time) of the length of the adhesive tape Tp necessary for sealing one box Bx. Thus, it is also possible to perform the tape pulling operation based on the number of sealing operations. In the case of performing such control, the roller position detection sensor 48 is unnecessary and can be omitted. However, since there may be an error in the length of the supplied adhesive tape Tps supplied to the outside, it is preferable that the roller position detection sensor 48 be provided.

  Further, in the tape feeding unit 4, the length of the supplied adhesive tape Tps wound around the position fixing roller 44 from the position fixing roller 43 through the drawing roller 46 is adjusted sufficiently long and detected by the roller position detection sensor 48. The roller position to be set may be variable. Then, in the tape pulling operation, the same length as the length of the adhesive tape Tp used in one pasting operation of the tape sticking device 2 may be pulled out. By doing this, it is possible to use one tape supply device 3 even if it is a tape sticking device in which the required length of one adhesive tape is different. Instead of the roller position detection sensor 48, a sensor that measures the displacement amount of the drawing roller 46 from the first position P1 may be used. The control unit 35 performs control such that the drawing operation is performed when the displacement amount of the drawing roller 46 at the first position P1 reaches the determined displacement amount. With such a configuration, it is possible to pull out by the pulling out operation even if the length of the adhesive tape required in one pasting operation is changed only by changing the determined displacement amount set in the control unit 35. The length of the supplied adhesive tape Tps can be easily changed to an integral multiple (including one) of the adhesive tape required in one pasting operation.

  In the present embodiment, the tape feeding unit 4 includes a drawing roller 41, fixed rollers 42, 43 and 44, a supply roller 45, and a drawing roller 46. However, the number of rollers of the tape delivery unit 4 is not limited to this. It is sufficient if at least the drawing roller 41, the supply roller 45, and the drawing roller 46 are provided, and the drawing roller 46 can move so as to approach or separate from the drawing roller 41 and the supply roller 45.

  Next, returning to FIG. 4, the other configuration of the tape supply device 3 will be described. As shown in FIG. 4, the control unit 35 is also connected to the operation unit 36 and the notification unit 37. The control unit 35 grasps the operation of each part of the tape supply device 3 and controls the operation of each part. The control unit 35 includes processing circuits such as a CPU and an MPU. The processing circuit acquires information from various sensors and the like, and issues an operation instruction to a connected part based on the acquired information. The processing circuit may be a dedicated circuit for performing predetermined processing, or includes a general-purpose processing unit, and activates a processing program (software, application) stored in a storage unit (not shown). Then, corresponding processing may be performed. In addition, about the process to parts other than the operation part 36 and the notification part 37 among the parts connected to the control part 35, since it is mentioned above, it omits it here.

  The operation unit 36 receives a user's operation on the tape supply device 3. The operation unit 36 includes an automatic / manual changeover switch 361 and a tape change switch 362. Although the details will be described later, the tape supply device 3 is provided with an automatic mode for automatically performing a tape changing operation for changing the standby adhesive tape Tpw to the supplied adhesive tape Tps, and a manual mode for performing manually. The automatic / manual changeover switch 361 is a switch for switching between the automatic mode and the manual mode. The automatic / manual switching switch 361 may be a push button switch, or may be a switch that switches the mode by rotating. With regard to the switch configuration, it is possible to widely adopt switches that are easy for the user to switch modes or understand the current operation mode, and are easy to operate. The tape change switch 362 is a switch used in the manual mode, and operates in the manual mode to perform an operation of connecting the standby adhesive tape Tpw to the supply adhesive tape Tps. The operation unit 36 may also include other switches, such as an emergency stop switch and an activation switch. The content of the operation performed using the operation unit 36 is sent to the control unit 35.

  The notification unit 37 notifies the current status of the tape supply device 3. For example, the notification unit 37 is configured to turn on lamps of different colors, and when the remaining amount of the tape winding from which the supply adhesive tape Tps is pulled out is sufficient, the notification unit 37 of the first color (for example, green) Turn on the lamp. In addition, when the remaining amount of the tape winding decreases below a certain amount, the second color (for example, red) lamp may be turned on. For example, a lamp, a speaker or the like may be provided as the notification unit 37. In addition, a display unit such as liquid crystal may be provided and displayed on the display unit. When the tape supply device 3 is configured to include a display unit such as liquid crystal, a part or all of the operation unit 36 is configured by a so-called touch panel that performs operation input by touching an image displayed on the display unit. You may

  Next, a switching operation for switching the standby adhesive tape Tpw to the supply adhesive tape Tps will be described. FIG. 11 is a flow chart showing the operation of supplying the adhesive tape by the tape supply device according to the present invention. FIG. 12 is a view showing the tape supply device in a state where the remaining amount of tape of the first tape roll stored in the first tape storage unit is exhausted. FIG. 13 is a view showing the tape supply device in a state where the standby adhesive tape is attached to the supply adhesive tape in the tape reconnection unit. FIG. 14 is a view showing the tape supply device when cutting the supply adhesive tape. FIG. 15 is a view showing the tape supply device when the standby pressure-sensitive adhesive tape is spliced to the supply pressure-sensitive adhesive tape.

  In the flowchart shown in FIG. 11, in the initial state, as shown in FIG. 3, the adhesive tape Tp stored in the first tape container 31 and drawn from the first tape roll Ra1 is the supplied adhesive tape Tps. The adhesive tape Tp drawn from the second tape roll Ra2 stored in the 2 tape storage unit 32 is a standby adhesive tape Tpw.

  In a state in which the tape supply device 3 supplies the adhesive tape Tp to the tape application device 2, the control unit 35 stores the tape roll supplying the supplied adhesive tape Tps, that is, the initial stage The first tape storage unit 31 is recognized in the state. First, the control unit 35 acquires information on the remaining amount of the first tape roll Ra1 from the first remaining amount detection sensor 312 of the first tape storage unit 31 (step S101). The first remaining amount detection sensor 312 emits light from the light source to the first tape winding Ra1. Then, when the remaining amount of the first tape roll Ra1 is large, the light from the light source is blocked by the first tape roll Ra1. Therefore, the signal from the first remaining amount detection sensor 312 to the control unit 35 is Low when the remaining amount of the first tape winding Ra1 is large, and switches to Hi when the remaining amount is exhausted. Note that the signal is an example, and thus the present invention is not limited to this. However, when the remaining amount is exhausted, the signal is switched or a signal is output.

  Based on the information from the first remaining amount detection sensor 31, it is checked whether the remaining amount of tape in the first tape roll Rs1 is sufficient to supply the tape (step S102). Note that the remaining amount sufficient to supply the tape includes, for example, the remaining amount of the first tape roll Ra1 and the supplied adhesive tape Tps disposed from the first tape storage unit 31 to the tape splicing unit 33. The sum of the length and the length may be longer than the length of the supplied adhesive tape Tps pulled out by the pulling operation of the tape feeding unit 4.

  As shown in FIG. 3, when the remaining tape amount of the first tape roll Ra1 is sufficient to supply the tape (in the case of Yes in step S102), the control unit 35 receives the information from the roller position detection sensor 48. Based on the information, the position of the drawing roller 46 is acquired (step S103). Then, the control unit 35 confirms whether or not the position of the drawing roller 46 is at the second position P2 (step S104). When the drawing roller 46 is not at the second position P2 (No in step S104), the control unit 35 returns to step S103, and acquires the position of the drawing roller 46.

  When the drawing-out roller 46 is in the second position P2 (in the case of Yes in step S104), the control unit 35 sends an instruction to the roller driving unit 47 and operates the roller driving unit 47 to move the drawing-out roller 46 to the first position P1. The drawing operation to be moved to is executed (step S105). At this time, the supplied adhesive tape Tps is pulled out from the first tape roll Ra1. Thereafter, the process returns to the detection of the remaining amount of the first tape winding Ra1 (step S101).

  The control unit 35 can acquire the number of times the sticking operation of sticking the adhesive tape Tp is performed from the tape sticking device 2, and the length of the supplied adhesive tape Tps drawn at the time of the tape pulling operation is a request in the sticking operation. In the case of an integral multiple (including one) of the adhesive tape Tp, the control unit 35 may obtain the number of sticking operations instead of detecting the position of the drawing roller 46 in step S103. Then, in step S104, it may be determined whether the drawing operation is to be performed based on the fact that the number of pasting operations after the previous drawing operation has reached a certain number.

  Further, as shown in FIG. 12, when the remaining amount of the first tape roll Ra1 is depleted or almost eliminated (No in step S102), the control unit 35 sends an instruction to the notification unit 37, and the user is notified to the user. Then, a notification to change the standby adhesive tape Tpw to the supply adhesive tape Tps is executed (step S106). Here, the lamp lighting and sound notification are performed.

  In the tape reconnection unit 33, when the user presses the tape change switch while the remaining amount of the tape winding is smaller than a predetermined amount, the manual reconnection mode for reattaching the standby adhesive tape Tpw to the supplied adhesive tape Tps The controller 35 has an automatic reconnection mode for automatically switching the standby adhesive tape Tpw to the supply adhesive tape Tps based on the information from the first remaining amount detection sensor 312 or the second remaining amount detection sensor 322. . For example, when the standby adhesive tape Tpw is reconnected to the supply adhesive tape Tps in the automatic reconnection mode, in order to reliably connect the adhesive tape Tps, the rear end of the supply adhesive tape Tps is rejoined with a certain margin. On the other hand, in the manual reconnection mode, the user visually checks the length of the supplied adhesive tape Tps, and the user judges and reconnects the standby adhesive tape Tpw with the supplied adhesive tape Tps, so the vicinity of the rear end of the supplied adhesive tape Tps. It is possible to connect the standby adhesive tape Tpw to. In other words, some use of adhesive tape is generated, but switching between automatic connection mode with less trouble for the user because automatic connection is changed, and manual transfer mode with little waste of adhesive tape but requiring much time for the user It is possible to

  Then, the control unit 35 confirms whether or not the manual reconnection mode is currently set (step S107). In the manual reconnection mode (Yes in step S107), the control unit 35 confirms whether the tape replacement switch 362 has been pressed (step S108). When the tape replacement switch 362 is not pressed (No in step S108), the control unit 35 further determines that the user may supply the supplied adhesive tape Tps from the first tape roll Ra1. It recognizes and sends out the supply adhesive tape Tps (step S103). The subsequent operation is the same as that described above, and thus will not be described.

  Further, the control unit is not in the manual reconnection mode (in the automatic reconnection mode) (in the case of No in step S107) and in the manual reconnection mode when the tape replacement switch 362 is pressed (in the case of Yes in step S108). 35 sends an instruction to the first holding plate driving unit 334 and the second holding plate driving unit 336 to bring the first holding plate unit 333 and the second holding plate unit 335 into contact with each other (step S109). At this time, the standby adhesive tape Tpw held by the second holding plate portion 335 is attached to the supplied adhesive tape Tps disposed between the first holding plate portion 333 and the second holding plate portion 335. That is, the standby adhesive tape Tpw is connected to the supply adhesive tape Tps (see FIG. 13).

  Then, as shown in FIG. 14, the control unit 35 sends an instruction to the first cutter 341, and causes the first cutter 341 to cut the supplied adhesive tape Tps (step S110). Then, the control unit 35 sends an instruction to the first holding plate driving unit 334 and the second holding plate driving unit 336, and returns the first holding plate unit 333 and the second holding plate unit 335 to their original positions (step S111). . As a result, the leading end of the standby adhesive tape Tpw is attached to the rear end of the supply adhesive tape Tps, thereby connecting the standby adhesive tape Tpw to the rear end of the supply adhesive tape Tps. Thus, the supplied adhesive tape Tps is stored in the second tape storage section 32 from the adhesive tape Tp drawn from the first tape roll Ra1 stored in the first tape storage section 31. The adhesive tape Tp is pulled out of the tape.

  In the tape feeding device 3, the timing at which the tape feeding unit 4 feeds the adhesive tape to the tape sticking device 2 differs from the timing at which the adhesive tape is pulled out from the tape roll. That is, the tape feeding unit 4 does not pull out the adhesive tape from the tape winding at the timing when the adhesive tape is fed to the tape sticking device 2. Then, in anticipation of the timing at which the control unit 35 and the tape delivery unit 4 are delivering the tape, the standby adhesive tape is spliced to the supply adhesive tape at the tape splicing unit. Thereby, in the tape supply device 3, it is possible to reconnect the adhesive tape without stopping the supply of the tape. In addition, since the tape feeding unit 4 does not perform the operation of peeling off the adhesive tape from the tape winding at the timing of feeding the adhesive tape because the timings are different, the tension of the adhesive tape being fed is made constant or substantially constant. It is possible to keep.

  In other words, for example, when the tape drive unit 47 of the tape delivery unit 4 is operating, the control unit 35 prevents the operation instruction from being sent to each unit of the tape reconnection unit 33; conversely, the tape reconnection unit 33 When the respective units are operating, the adhesive tape is reconnected without stopping the supply of the tape by operating according to an algorithm for preventing the operation instruction from being sent to the tape drive unit 47 of the tape feeding unit 4. Is possible.

  The tape reconnection unit 33 reattaches the standby adhesive tape Tpw to the supply adhesive tape Tps by the above operation. Then, as shown in FIG. 15, the new tape roll is accommodated as the first tape roll Ra1, and the leading end of the adhesive tape Tp pulled out from the first tape roll Ra1 is held by the first holding plate portion 333. The standby adhesive tape Tpw is used.

  By using the tape supply device 3 according to the present invention in the sealing device A, the tape winding body for supplying the adhesive tape is switched without stopping the supply of the adhesive tape. Therefore, it is not necessary to stop the transport apparatus 1, that is, the production line, for replacing the tape winding as in the conventional apparatus.

  In the tape supply device 3, the tape roll is a consumable and needs to be replaced. The tape supply device 3 can individually open and close the first door 301 for opening and closing the first tape storage unit 31 and the second door 302 for opening and closing the second tape storage unit 32 at the time of tape replacement. Therefore, when replacing one tape winding of the first tape storage unit 31 and the second tape storage unit 32, it is not necessary to stop the other. Therefore, in the tape supply device 3, the tape roll can be replaced without stopping the supply of the adhesive tape. Also from this point, it is possible to shorten the tact time because it is not necessary to stop the production line while the tape exchange takes place. As a result, cost reduction of a product is possible.

  Moreover, it is possible to replace the tape winding body without moving the tape supply device 2 with respect to the transport device 1 during the sealing operation. Therefore, since the mechanism for moving the tape supply device 2 is unnecessary, the configuration of the sealing device A can be simplified. In addition, since the tape feeding device 2 is not moved and the adhesive tape is supplied from the tape feeding device 3 disposed outside the conveying device 1, the degree of freedom in the layout of the sealing device A can be increased. It is possible.
