It has a second holding portion that is arranged and holds the same surface as the first holding portion of the supplied adhesive tape. Non-adhesive treatment is applied to at least the surface of the cutting table that comes into contact with the adhesive surface of the supplied adhesive tape, and the cutting edge of the cutting blade moves into the gap to release the supplied adhesive tape. Be disconnected. With such a configuration, tension can be generated in the supplied adhesive tape at the time of cutting, so that the supplied adhesive tape can be reliably cut. Further, by applying a non-adhesive treatment to the surface that comes into contact with the adhesive surface, the supplied adhesive tape after cutting is easily peeled off from the tape cutting portion. As a result, even after the supply adhesive tape is switched, the supply adhesive tape is smoothly supplied.

In the above configuration, in the tape feeding section, each time the supplied adhesive tape is fed out for a certain length, the supplied adhesive tape is wound around the supplied adhesive tape having the same length as the length to which the supplied adhesive tape is sent. Pull out from the tape roll. By doing so, the tape feeding unit can shift the timing of tape feeding from the timing of tape pulling out. By shifting these timings, it becomes easy to reconnect the standby adhesive tape to the supply adhesive tape. Further, the tension of the adhesive tape sent out from the tape feeding portion becomes constant or substantially constant, and the tape sticking operation of the sticking device can be efficiently performed accordingly.

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 prepare. The first tape supply device 3a and the second tape supply device 3b have the same configuration except that the destination of the drawn adhesive tape Tp is different. Therefore, in the following description, the tape supply device 3 will be described as a representative of the first tape supply device 3a and the second tape supply device 3b. Further, in each drawing used in the following description, it is assumed that the adhesive tape Tp inside the tape supply device 3 is arranged perpendicular to the paper surface. Further, the adhesive tape Tp is assumed to be conveyed 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 an example of the tape supply device according to the present invention in a state where the first door is opened. FIG. 3 is a diagram showing a schematic configuration of the tape supply device shown in FIG. 2. FIG. 4 is a block diagram of the tape supply device according to the present invention.

In the following description, the adhesive tape supplied to the tape affixing device 2 in the tape supply device 3 is referred to as a supply adhesive tape Tps, and is indicated by a thick solid line in the figure. Further, the adhesive tape drawn from a tape winding body different from the supplied adhesive tape and waiting at the tape connecting portion 33 is referred to as a standby adhesive tape Tpw, and is indicated by a thick line of a long-dot chain line in the figure. For example, in the tape supply device 3 shown in FIG. 3, the adhesive tape pulled out from the first tape winding body Ra1 stored in the first tape storage unit 31 is the supply adhesive tape Tps, and the second tape is stored in the second tape. The adhesive tape pulled out from the tape winding body Ra2 is the standby adhesive tape Tpw. The supply adhesive tape Tps and the standby adhesive tape Tpw are names for convenience of explanation, and are substantially the same members. Therefore, unless a particular distinction is required, both the supplied adhesive tape Tps and the standby adhesive tape Tpw may be described as the adhesive tape Tp.

As shown in FIGS. 1 and 2, the tape supply device 3 includes a main body portion 300, a first door 301 that opens and closes the upper portion of the main body portion 300, and a second door 302 that opens and closes the lower portion of the main body portion 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 portion 300 at an end portion opposite to the grip portion 303. The first door 301 is arranged so as to open and close the first tape storage portion 31. The second door 302 is provided with a grip portion 304 (handle 304). The second door 302 has an end portion opposite to the grip portion 304 rotatably supported with respect to the main body portion 300. The second door 302 is arranged so as to open and close the second tape storage portion 34. That is, the tape supply device 3 opens and closes the first tape storage unit 31 at the first door 301, and opens and closes the second tape storage unit 32 at 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 winding body is a consumable item and needs to be replaced. In the tape supply device 3, the first tape storage unit 31 and the second tape storage unit 32 can be individually opened and closed when the tape is replaced. Therefore, when one of the tape winding bodies of the first tape storage unit 31 and the second tape storage unit 32 is replaced, 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 connecting unit 33, and a tape feeding unit 4. The first tape storage section 31, the second tape storage section 32, and the tape connecting section 33 are housed inside the main body section 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 side by side. Then, the first tape storage unit 31 stores the first tape winding body Ra1 around which the adhesive tape Tp supplied to the tape affixing device 2 (here, referred to as the supplied adhesive tape Tps) is wound. The first tape storage unit 31 includes a first storage roller 311, a first remaining amount detection sensor 312, and a tape holding unit 313.

The first storage roller 311 is rotatable, and the first tape winding body Ra1 is attached to the first storage roller 311. The first storage roller 311 rotates together with the first tape winding body Ra1 when the supply adhesive tape Tp is sent out. The adhesive tape Tp from the first tape winding body Ra1 is pulled out by the pull-out operation described later of the tape feeding unit 4.

The first remaining amount detection sensor 312 is arranged in the vicinity of the first storage roller 311. The first remaining amount detection sensor 312 is an example of the remaining amount detecting unit, and includes, for example, a light source that irradiates the first tape winding body Ra1 with light, and a light receiving element that detects light from the light source. The light source irradiates the first tape winding body Ra1 with light from a predetermined position. The light receiving element is arranged at a position where light from the light source is received when the remaining amount of the first tape winding Ra1 reaches a certain amount, for example, when the remaining amount of tape in the first tape winding Ra1 is exhausted. Has been done. With such a configuration, the first remaining amount detection sensor 312 can detect that the remaining amount of the first tape winding body Ra1 stored in the first tape storage unit 31 has run out. The light from the light source may be irradiated to the first tape winding body Ra1 stored in the first tape storage unit 31 in the axial direction or in the tangential direction. In either case, the remaining amount of the first tape winding body Ra1 can be detected by adjusting the positions of the light source and the light receiving element. Further, as the first remaining amount detection sensor 312, the rotation angle of the roller support portion 314 described later and / or the position of the holding roller 315 of the tape holding portion 313 are detected, and the remaining amount of the first tape winding body Ra1 is detected. It may be used as a sensor.

The first remaining amount detection sensor 312 is connected to the control unit 35 (see FIG. 4). Then, when the first remaining amount detection sensor 312 detects that the remaining amount of the first tape winding body Ra1 stored in the first tape storage unit 31 has run out, 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 based on the information from the first remaining amount detection sensor 312. By doing so, the tip of the standby adhesive tape Tpw can be attached as close to the rear end of the supply adhesive tape Tps as possible, and the amount of 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 winding body Ra1 stored in the first tape storage unit 31. However, it is not limited to this. For example, the presence or absence of the adhesive tape Tp arranged in the vicinity of the tape reconnecting portion 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 winding body Ra1 stored in the first tape storage unit 31, the adhesive tape Tp is pulled by the tape feeding unit 4, so that the adhesive tape wound around the outermost circumference is peeled off. Be sent out. Here, the adhesive tape and the tape winding body will be described. Here, the adhesive tape Tp is a tape (OPP tape) whose base material is OPP (polypropylene), and has a stronger adhesive force on the adhesive surface than a tape whose base material is paper (so-called kraft tape). When the adhesive tape Tp is peeled off from the tape winding body, it is often peeled off at once by a certain length (indefinite length).

When the adhesive tape is pulled by the pull-out operation of the tape feeding unit 4 and the adhesive tape Tp having a certain length is peeled off from the first tape winding body Ra1 stored in the first tape storage unit 31, the tape is supplied. It causes the adhesive tape Tp to loosen inside the device 3. Therefore, the first tape accommodating portion 31 suppresses the adhesive tape Tp from being peeled off from the first tape winding body Ra1 at once by the tape pressing portion 313. Here, the tape holding portion 313 will be described.

The tape holding portion 313 includes a roller support portion 314, a holding roller 315, a rotating shaft 316, and a tape bending roller 317. The roller support portion 314 is a long member, and has a configuration in which the adhesive tape Tp can pass through the inside. The roller support portion 314 has, for example, a configuration in which a pair of long plate members are faced to each other and supported. A presser roller 315 is rotatably supported at one end of the roller support portion 314. Further, the other end of the roller support portion 314 is rotatably supported by the rotation shaft 316. Then, a bending roller 317 is rotatably attached to the rotating shaft 316.

The roller support portion 314 is rotatably supported by the rotation shaft 316, and the roller support portion 314 rotates about the rotation shaft 316 so that the presser roller 315 rotatably supported by the roller support portion 314 is provided. , Approaches or separates from the central axis of the first tape winding body Ra1. Then, the adhesive tape Tp is wound around the presser roller 315 so that the non-adhesive surface of the adhesive tape Tp wound around the first tape winding body Ra1 comes into contact with the presser roller 315.

Then, the adhesive tape Tp wound around the presser roller 315 intersects with the roller support portion 314 and is wound around the bending roller 317. The bending roller 317 comes into contact with the adhesive surface of the adhesive tape Tp. The adhesive tape Tp wound around the bending roller 317 is arranged in the tape reconnecting portion 33. Here, the adhesive tape Tp from the first tape winding body Ra1 is the supply adhesive tape Tps, and the supply adhesive tape Tps passes through the tape reconnecting unit 33 and is sent to the tape feeding unit 4.

The adhesive tape Tp from the first tape winding body Ra1 is wound around the presser roller 315 and the bending roller 317, and is bent by the presser roller 315. Then, in this state, the adhesive tape Tp is pulled in the feeding direction. When the adhesive tape Tp is pulled, that is, when tension in the transport direction acts on the adhesive tape Tp, the adhesive tape Tp urges the presser roller 315 with a force toward the central axis of the presser roller 315. When the presser roller 315 is in contact with the outer peripheral surface of the first tape winding body Ra1, the point where the adhesive tape Tp is pulled out from the first tape winding body Ra1 is that the first tape winding body Ra1 and the pressing roller 315 It is a point of contact. If the center angle of the region around which the adhesive tape Tp of the presser roller 315 is wound is larger than 90 degrees, the tension of the adhesive tape Tp pushes the presser roller 315 to the contact point with the first tape winding body Ra1. Contains force components. That is, the tension of the adhesive tape Tp applies a force to the presser roller 315 in the direction approaching the central axis of the first tape winding body Ra1. Therefore, the center angle of the region around which the adhesive tape Tp of the presser roller 315 is wound is preferably larger than 90 degrees, more preferably around 180 degrees or more.

In this way, by winding the adhesive tape Tp around the tape pressing portion 313 and arranging it, the pressing roller 315 is placed on the outer periphery of the first tape winding body Ra1 due to the tension of the adhesive tape Tp when the adhesive tape Tp is pulled in the feeding direction. Pressed against the surface. As a result, when the adhesive tape Tp is peeled off from the first tape winding body Ra1, a certain length is not peeled off at once, or it becomes difficult to be peeled off at once. For this reason, the adhesive tape Tp is difficult to loosen inside the tape supply device 3, and the adhesive tape Tp loosens and sticks to the inside of the tape supply device 3 or the adhesive surfaces of the adhesive tape Tp stick to each other. Can be suppressed.

Further, as shown in FIG. 12, which will be described later, the presser roller 315 of the tape presser portion 313 is attached to the core of the first tape winding body Ra1, that is, the first storage roller 311 by the tension of the wound supply adhesive tape Tps. Be pressed. Further, in the tape pressing portion 313, the pressing roller 315 is pressed against the outer peripheral surface of the first tape winding body Ra1 by the tension of the adhesive tape Tp. Therefore, when the remaining amount of the adhesive tape Tp is exhausted, the force pressed against the first tape winding body Ra1 is released. At this time, it is preferable that the presser roller 315 and the roller support portion 314 are formed so as to return to an initial position that does not get in the way when the new first tape winding body Ra1 is stored in the first tape storage portion 31. Such a configuration may include an urging member for urging the roller support portion 314, or may be configured to return to the original position by its own weight.

Then, the adhesive tape Tp wound around the presser roller 315 intersects with the roller support portion 314 and is wound around the bending roller 317. The bending roller 317 comes into 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 reconnecting unit 33. Here, the adhesive tape Tp from the first tape winding body Ra1 is the supply adhesive tape Tps, and the supply adhesive tape Tps passes through the tape reconnecting unit 33 and is sent to the tape feeding unit 4.

In the tape pressing portion 313, the pressing roller 315 comes into contact with the non-adhesive surface of the adhesive tape Tp, and the bending roller 317 comes into contact with the adhesive surface of the adhesive tape Tp. Therefore, the surface material and / or shape may be different between the pressing roller 315 and the bending roller 317. For example, the presser roller 315 that comes into contact with the non-adhesive surface of the adhesive tape Tp is made of a material and / or shape that has high friction with the non-adhesive surface of the adhesive tape Tp. Further, the bending roller 317 that comes into contact with the adhesive surface of the adhesive tape Tp is made of a material and / or shape that allows the adhesive surface of the adhesive tape Tp to be easily peeled off. By separating the material and / or shape of the roller in this way, the adhesive tape Tp can be smoothly conveyed inside the tape supply device 3. Further, 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 suppressed from remaining on the roller, and the adhesive force of the adhesive tape Tp sent to the tape affixing device 2 can be suppressed. Can be suppressed. As a shape in which the adhesive tape does not easily stick, for example, a method of providing a slit on the surface of the roller to reduce the contact area can be mentioned.

In addition to the presser roller 315 and the bending roller 317, the tape supply device 3 also has a roller around which the adhesive tape Tp is wound. As for such rollers, unless otherwise specified, the rollers that come into contact with the non-adhesive surface are made of a material and / or shape that has a high frictional force with the non-adhesive surface, and the rollers that come into contact with the adhesive surface are used. Shall adopt a material and / or shape that the adhesive surface can be easily peeled off. Further, the same may be applied to the transport rollers 201 and 202 of the tape affixing device 2.

The second tape storage unit 32 is arranged 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 holding unit 323. Since the second storage roller 321 has the same configuration as the first storage roller 311 and the second remaining amount detection sensor 322 has the same configuration as the first remaining amount detection sensor 312, detailed description thereof will be omitted. Further, the tape pressing portion 323 has substantially the same configuration as the tape pressing portion 313, although the form of arrangement of the adhesive tape Tp is different. Therefore, a detailed description of the tape holding portion 323 will be omitted. Further, the roller support portion 324, the presser roller 325, the rotary shaft 326 and the tape bending roller 327 of the tape presser portion 323 are each of the roller support portion 314, the presser roller 315, the rotary shaft 316 and the tape bending roller 317 of the tape presser portion 313. It has substantially the same configuration as.

That is, the second tape winding body Ra2 around which the adhesive tape Tp is wound is arranged in the second tape accommodating portion 32. The central axis of the second storage roller 321 of the second tape storage unit 32 and the first storage roller 311 of the first tape storage unit 31 are parallel to each other, that is, the central axis is relative to the plane of the drawing shown in FIG. Arranged so that they are vertical. The rollers arranged inside the tape supply device 3 are arranged so that the central axis is perpendicular to the drawing shown in FIG. By arranging in this way, the adhesive tape Tp wound around the roller can be made perpendicular to the drawing shown in FIG.

The adhesive tape Tp pulled out from the first tape winding body Ra1 stored in the first tape storage unit 31 and the adhesive tape Tp drawn out from the second tape winding body Ra2 stored in the second tape storage unit 32, respectively. It is sent to the tape reconnecting unit 33. As shown in FIG. 3, the tape reconnecting unit 33 is arranged 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. Has been done. The tape reconnecting unit 33 does not have to be at the center of the first tape storage unit 31 and the second tape storage unit 32, and may be displaced from the center to one side. Further, it does not have to be between the first tape storage unit 31 and the second tape storage unit 32, and is located at a position farther than the other with either one of the first tape storage unit 31 and the second tape storage unit 32 sandwiched between them. 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 reconnection unit 33 is the first tape storage unit 31 and the second tape storage unit 32. It is preferable to be arranged between and.

<Tape replacement part>
The tape reconnecting portion 33 includes a tape cutting portion 34. Further, the tape reconnecting portion 33 includes a first pull-in roller 331, a second pull-in roller 332, a first holding plate portion 333, a first holding plate driving portion 334, a second holding plate portion 335, and a second. A holding plate drive unit 336 is provided.

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

The first pull-in roller 331 and the second pull-in roller 332 only bend the direction of the adhesive tape Tp, but the present invention is not limited to this. For example, even when the remaining amount of the supplied adhesive tape in the tape winding is exhausted, the supply adhesive tape passing through the tape reconnecting portion 33 may be maintained in a state where a certain amount of tension is applied. As such a configuration, for example, a roller provided with a roller in contact with each of the first pull-in roller 331 and the second pull-in roller 332 may be provided, and the supply adhesive tape Tps may be sandwiched and held. In addition to these, it is possible to widely adopt a configuration that can apply tension to the adhesive tape.

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 so as 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 holding surfaces, respectively. The first holding plate portion 333 and the second holding plate portion 335 hold the tip portion of the standby adhesive tape Tpw in the transport direction on the holding surface. In the tape supply device 3 shown in FIG. 3, the adhesive tape Tp drawn out from the second tape winding body Ra2 is the standby adhesive tape Tpw. Therefore, the tip of the standby adhesive tape Tpw wound around the second pull-in roller 332 is held on 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 the portion of the second holding plate portion 335 that comes into contact with the adhesive tape Tp is formed of a material such as silicon rubber that makes it difficult for the adhesive surface to adhere, that is, the force (adhesive force) for which the adhesive surface adheres is weakened. Has been done. It should be noted that at least the portion of the first holding plate portion 333 that comes into contact with the adhesive tape Tp may be made of a material such as silicon rubber that does not easily adhere to the adhesive surface of the adhesive tape Tp, as in the case of the second holding plate portion 335. good. Further, the adhesive strength of the adhesive tape Tp is determined by the area to which the adhesive tape Tp is attached. Therefore, the adhesive strength may be adjusted by providing unevenness (grooves) on the surface of the adhesive tape Tp in contact with the adhesive tape Tp to reduce the sticking area.

The adhesive tape Tp drawn from the first tape winding body Ra1, that is, the supplied adhesive tape Tps, and the adhesive tape Tp drawn out from the second tape winding body Ra2, that is, the standby adhesive tape Tpw, both have an adhesive surface. It is facing down. Therefore, when the adhesive tape Tp drawn out from the second tape winding body Ra2 is used as the standby adhesive tape Tpw, the adhesive surface of the standby adhesive tape Tpw can be held by sticking it to the holding surface of the second holding plate portion 335. It is possible. On the other hand, as shown in FIG. 15 described later, the adhesive tape Tp drawn out from the first tape winding body 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, is sucked air from the holding surface to allow the standby adhesive tape Tpw. It may be provided with the suction part which holds. The suction portion may be provided on both the first holding plate portion 333 and the second holding plate portion 335.

The suction portion is configured to suck the adhesive tape by sucking air, but the present invention is not limited to this. For example, a configuration that can reliably hold the tip of the standby adhesive tape Tpw, such as one that uses static electricity or one that is coated with an adhesive having a slightly lower adhesive strength than the adhesive surface, can be widely adopted.

A first holding plate driving portion 334 is attached to the first holding plate portion 333. The first holding plate drive unit 334 is an actuator that moves the first holding plate unit 333 up and down. The first holding plate drive unit 334 may be, for example, one that utilizes pneumatic pressure such as a piston / cylinder, or one that is provided with a solenoid or the like and is electrically driven. A configuration capable of reliably operating the first holding plate portion 333 can be widely adopted. The first holding plate drive unit 334 is connected to the control unit 35 (see FIG. 4). The first holding plate drive unit 334 operates according to the instructions of the control unit 35.

A second holding plate driving portion 336 is attached to the second holding plate portion 335. The second holding plate drive unit 336 is an actuator that moves the second holding plate unit 335 up and down. The second holding plate drive unit 336 may be, for example, one that utilizes pneumatic pressure such as a piston / cylinder, or one that is provided with a solenoid or the like and is electrically driven. A configuration capable of reliably operating the second holding plate portion 335 can be widely adopted. 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 according to the 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 into contact with each other. As a result, the supply adhesive tape Tps passing between the first holding plate portion 333 and the second holding plate portion 335 and the tip of the standby adhesive tape Tpw held by the first holding plate portion 333 or the second holding plate portion 335. Are pasted together. Although the details will be described later, the tape reconnecting unit 33 supplies the standby adhesive tape Tpw by bonding 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. The tape reconnecting operation of reconnecting to the adhesive tape Tps is executed. In the present embodiment, both the first holding plate portion 333 and the second holding plate portion 335 are configured to move, but one of them may be configured to approach and separate from the other.

<Tape cutting part>
Here, the details of the tape cutting portion 34 will be described with reference to a new drawing. FIG. 5 is an enlarged view showing a state in which the supply adhesive tape arranged on the upper side of the cutting table is cut at the tape cutting portion. Further, FIG. 6 is an enlarged view showing a state in which the supply adhesive tape arranged on the lower side of the cutting table is cut at the tape cutting portion. The tape cutting portion 34 cuts the supplied adhesive tape Tps after attaching the standby adhesive tape Tpw to the supplied adhesive tape Tps. In FIG. 5, the adhesive tape Tp drawn out from the first tape winding body Ra1 is used as the supply adhesive tape Tps.

As shown in FIG. 5, the tape cutting portion 34 includes a cutting table 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 arranged with a gap on the upstream side and the downstream side of the supply adhesive tape Tps in the supply direction. The first holding portion 343 is arranged on the downstream side of the second holding portion 344 in the supply direction of the supply adhesive tape Tps.

The first cutter 341 is arranged above the cutting table 340. The first cutter 341 houses a cutting blade portion 345 extending with respect to the cutting table 340. 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 table 340. Then, the cutting blade portion 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 portion 345 enters between the first holding portion 343 and the second holding portion 344, the cutting edge cuts the supplied adhesive tape Tps.

For example, when the cutting blade portion 345 moves into the gap between the first holding portion 343 and the second holding portion 344, the supply 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 from 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.

When the adhesive tape Tp drawn out from the first tape winding body Ra1 is the supplied adhesive tape Tps, the adhesive surface is on the lower side, that is, on the cutting table 340 side. Therefore, the supply adhesive tape Tps is pushed by the cutting blade portion 345 and adheres to both the first holding portion 343 and the second holding portion 344. By sticking the adhesive surface of the supply adhesive tape Tps to the first holding portion 343 and the second holding portion 344, the supply adhesive tape Tps is fixed and the tension increases when pressed by the cutting blade portion 345. This makes it possible to cut the supplied adhesive tape Tps with the cutting edge of the cutting blade portion 345 even when the tension of the portion of the supplied adhesive tape Tps facing the cutting table 340 is low.

In the tape cutting portion 34, the supplied adhesive tape Tps is attached to the first holding portion 343 and the second holding portion 344 in order to obtain a tension capable of cutting with the cutting blade portion 345. On the other hand, if the supplied adhesive tape Tps is firmly attached to the first holding portion 343 and the second holding portion 344, it becomes difficult for the adhesive tape Tp to be pulled out, and the supply operation of the adhesive tape may become unstable. be. Further, when a new tape winding body is attached, it becomes difficult to remove the adhesive tape Tp attached to the first holding portion 343, and the workability of the tape winding body replacement work deteriorates. Therefore, the cutting table 340 may be subjected to a non-adhesive treatment on the portion in contact with the adhesive surface of the supplied adhesive tape Tps.

Examples of the non-adhesive treatment include, but are not limited to, adron treatment. For example, the adhesive strength may be adjusted by forming innumerable grooves on the surfaces of the first holding portion 343 and the second holding portion 344 where the adhesive surfaces of the supplied adhesive tape Tp come into contact with each other to reduce the contact area. .. In addition, as a non-adhesive treatment, the adhesive tape Tps supplied by the cutting edge of the cutting blade portion 345 is pressed to generate a tension that allows cutting, and the adhesive surface is peeled off so that no adhesive remains. It is preferable that the treatment is simple. As the surface on which the non-adhesive treatment is performed, the surface on which the supplied adhesive tape Tps faces can be mentioned. Further, a surface on which the supplied adhesive tape Tps may adhere at the time of cutting or after cutting, for example, a surface on the downstream side of the supply adhesive tape Tps of the first holding portion 343 in the supply direction, an inner surface of the gap, and the like can be mentioned. can.

Further, as shown in FIG. 6, a second cutter 342 is arranged under the cutting table 340. Then, the cutting blade portion 346 extends from the second cutter 342 toward the cutting table 340. The cutting blade portion 346 moves so as to insert the cutting edge toward the gap between the first holding portion 343 and the second holding portion 344, similarly to the cutting blade portion 345. When cutting the adhesive tape Tp drawn from the second tape winding body Ra2, the cutting edge of the cutting blade portion 346 comes into contact with the adhesive surface of the supplied adhesive tape Tps. That is, the supplied adhesive tape Tps adheres to the cutting edge of the cutting blade portion 346.

Further, the supply roller 45 of the tape feeding unit 4, which will be 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 inside the gap between the first holding portion 343 and the second holding portion 344, the cutting edge of the supply roller 45 and the cutting blade portion 346 The tension of the supply adhesive tape Tps during is increased. Therefore, even when the non-adhesive surface of the supplied adhesive tape Tps comes into contact with the first holding portion 343 and the second holding portion 344, the tension of the supplied adhesive tape Tps increases due to the movement of the cutting blade portion 346. Be disconnected. Since the area of the cutting edge of the cutting edge portion 346 is very small, the adhesive surface of the supplied adhesive tape Tps is narrow. Therefore, when the cutting blade portion 346 returns to the original position, the supply adhesive tape Tps adhering 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 table 340 facing the second cutter 342, that is, the lower surface, comes into contact with the non-adhesive surface of the supplied adhesive tape Tps. Therefore, the non-adhesive treatment may be performed or the non-adhesive treatment may not be performed. In the cutting table 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 treatment.

In the present embodiment, as the cutting table 340, the first holding portion 343 and the second holding portion 344 are arranged with a gap in the supply direction of the supply adhesive tape Tps, but the present invention is not limited to this. For example, as in the tape cutting portion 34B shown in FIG. 7, the cutting table 347 is recessed on the surface facing each of the first cutter 341 and the second cutter 342 on the side opposite to the first cutter 341 and the second cutter 342. It may be configured to have recesses 348 and 349.

<Tape delivery section>
The tape feeding unit 4 will be described. In the tape feeding section 4, the supply adhesive tape Tps that has passed through the tape reconnecting section 33 is arranged. As shown in FIG. 3 and the like, the tape feeding section 4 includes a pull-in roller 41, position fixing rollers 42, 43 and 44, a supply roller 45, a pull-out roller 46, a roller drive section 47, and a roller position detection sensor 48. (See FIG. 4).

In the tape feeding section 4, the supplied adhesive tape Tps drawn from the tape reconnecting section 3 is wound around the pull-in roller 41. Then, the supply adhesive tape Tps is wound around the lower side of the position fixing roller 43 arranged on the upper side and the lower side of the position fixing roller 42 arranged on the upper side. Further, the supply adhesive tape Tps is wound on the upper side of the pull-out roller 46 arranged laterally of the position fixing roller 43, and is wound on the lower side of the position fixing roller 44 arranged side by side with the position fixing roller 43. It is wound around. Finally, the supply adhesive tape Tps is wound around the upper side of the supply roller 45 arranged on the upper side and supplied to the tape application device 2.

The pull-in roller 41 and the position fixing rollers 42, 43 and 44 are rollers that can rotate at a predetermined (fixed position). As shown in FIG. 3, the supplied adhesive tape Tps is routed up and down to support the supplied adhesive tape Tps so as not to loosen.

A roller drive unit 47 is arranged at a portion intermediate between the position fixing roller 43 and the position fixing roller 44 in the lateral direction. The roller drive unit 47 rotatably supports the drawer roller 46. The roller drive unit 47 moves the drawer roller 46 so as to intersect (upward) 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 the instructions of the control unit 35. The roller drive unit 47 may be one that is linearly moved by using air pressure, such as a piston / cylinder, or one that is linearly moved by electric and magnetic forces. Although the details will be described later, the roller drive unit 47 moves the drawer roller 46 in a direction away from the position fixing rollers 43 and 44. The drawer roller 46 is supposed to move in the vertical direction, but is not limited to this. The direction is not particularly particular as long as it approaches and separates from the position fixing rollers 43 and 44.

The supply roller 45 is arranged side by side with the position fixing roller 42 in the lateral direction. The supply roller 45 is arranged on the most downstream side in the supply direction of the supply adhesive tape Tps in the tape delivery unit 4. The supply roller 45 includes a mechanism such as a one-way clutch and a ratchet that limits the rotation 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. As a result, the supply adhesive tape Tps and the supply roller 45 are relatively less slippery.

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 lead-in roller 46, such as one that uses light (infrared light, ultraviolet light, etc.), one that uses sound waves, one that has a physical switch such as a limit switch, and the like. A wide range of configurations can be adopted. The tape feeding unit 4 of the present embodiment employs an optical position sensor including a light source and a light receiving element. As shown in FIG. 4, the roller position detection sensor 48 is connected to the control unit 35, and the control unit 35 accurately grasps the position of the drawer roller 46 based on 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 a tape feeding unit in a state before supplying the adhesive tape to the tape applying device. FIG. 9 is a schematic view of a tape feeding portion in a state where an adhesive tape having a certain length is supplied to the tape attaching device. FIG. 10 is a schematic view of a tape feeding portion when the adhesive tape is pulled out from the tape winding body.

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

When the box body Bx is sealed by the tape sticking device 2, the adhesive tape Tp is pulled in the drawing direction by the transportation of the box body Bx, that is, in the direction indicated by the arrow line Ar1 in FIG. At this time, the pull-out roller 46 is pushed downward by the tension of the adhesive tape Tp and moves downward (see FIG. 9). When the adhesive tape Tp is pulled, the drawer roller 46 moves downward, so that the movement of the box Bx makes it difficult for the tape to be pulled out from the tape winding body. The roller drive unit 47 urges the drawer roller 46 upward to the extent that it does not interfere with the downward movement of the drawer roller 46, in other words, to the extent that the supplied adhesive tape Tps does not loosen.

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

As shown in FIG. 9, when the pull-out roller 46 moves to the lower end position (this position is referred to as the second position P2), the roller position detection sensor 48 detects that the pull-out roller 46 is in the second position P2. At this time, the control unit 35 sends an instruction to drive the roller drive unit 47, and the roller drive unit 47 moves the drawer roller 46 from the second position P2 to the first position P1. At this time, the pull-out 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 with respect to the pull-out 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 fed from the tape feeding section 4 to the tape sticking device 2 does not flow back to the tape feeding section 4. Further, 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 portion 4 does not increase or is difficult to increase. Therefore, as the pull-out roller 46 moves from the second position P2 to the first position P1, the supplied adhesive tape Tps is pulled out from the tape winding body (in FIG. 3, the first tape winding body Ra1) (see FIG. 10). .. Therefore, the operation of driving the tape drive unit 47 to move the extraction roller 46 is referred to as the tape extraction operation.

The tape feeding unit 4 drives the roller driving unit 47 each time the adhesive tape Tp having the length of the supplied adhesive tape Tps wound around the position fixing roller 44 is supplied from the position fixing roller 43 via the drawing roller 46. Then, the supplied adhesive tape Tps is pulled out from the tape winding body. Therefore, the length of the supplied adhesive tape Tps wound from the position fixing roller 43 through the drawing roller 46 to the position fixing roller 44 is the length of the adhesive tape Tp required to seal one box Bx. By setting it to an integral multiple (including 1 multiple), it is possible to perform a tape withdrawal operation between the sealing operations of the box body Bx. This makes it possible to smoothly supply the adhesive tape.

Further, the length of the supplied adhesive tape Tps drawn out by the movement of the pull-out roller 46 is set to an integral multiple (including 1 time) of the length of the adhesive tape Tp required to seal one box Bx. Therefore, it is also possible to execute the tape withdrawal operation based on the number of times of the boxing operation. When 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 is 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 via the drawing roller 46 is adjusted to be sufficiently long, and is detected by the roller position detection sensor 48. The roller position to be formed may be variable. Then, the tape can be pulled out by the same length as the length of the adhesive tape Tp used in one sticking operation of the tape sticking device 2. By doing so, it is possible to use one tape supply device 3 even if the tape sticking devices have different required lengths of the adhesive tape at one time. Instead of the roller position detection sensor 48, a sensor that measures the displacement amount of the pull-out roller 46 from the first position P1 may be used. The control unit 35 controls so as to perform a pull-out operation when the displacement amount of the pull-out roller 46 at the first position P1 reaches a predetermined displacement amount. With such a configuration, even if the length of the adhesive tape required for one sticking operation changes, it is pulled out by the pull-out operation only by changing the predetermined 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 1 times) of the adhesive tape required for one sticking operation.

In the present embodiment, the tape feeding unit 4 includes a pull-in roller 41, fixed rollers 42, 43, 44, a supply roller 45, and a pull-out roller 46. However, the number of rollers in the tape feeding unit 4 is not limited to this. At least, the pull-in roller 41, the supply roller 45, and the pull-out roller 46 may be provided, and the pull-out roller 46 may be movable so as to approach or separate from the pull-in roller 41 and the supply roller 45.

Next, returning to FIG. 4, other configurations of the tape supply device 3 will be described. As shown in FIG. 4, the operation unit 36 and the notification unit 37 are also connected to the control unit 35. 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 a processing circuit such as a CPU and an MPU. The processing circuit acquires information from various sensors and the like, and gives an operation instruction to the connected portion based on the acquired information. The processing circuit may be a dedicated circuit for performing a predetermined processing, or has a general-purpose processing unit and starts a processing program (software, application) stored in a storage unit (not shown). The corresponding process may be performed. Of the parts connected to the control unit 35, the processing for the parts other than the operation unit 36 and the notification unit 37 will be omitted here because they are described above.

The operation unit 36 receives the user's operation on the tape supply device 3. The operation unit 36 includes an automatic / manual connection switch 361 and a tape exchange switch 362. Although the details will be described later, the tape supply device 3 includes an automatic mode for automatically performing and a manual mode for manually connecting the standby adhesive tape Tpw to the supply adhesive tape Tps. The automatic / manual connection switch 361 is a switch for switching between the automatic mode and the manual mode. The automatic / manual connection switch 361 may be a push button switch or a switch for switching a mode by rotating the switch. As for the switch configuration, a switch that is easy for the user to switch modes or grasp the current operation mode and is easy to operate can be widely adopted. Further, the tape exchange switch 362 is a switch used in the manual mode, and is operated 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 a start 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 light lamps of different colors, and when the remaining amount of the tape winding from which the supplied adhesive tape Tps is pulled out is sufficient, the first color (for example, green) is used. Turn on the lamp. Further, when the remaining amount of the tape winding is less than a certain amount, the lamp of the second color (for example, red) may be turned on. The notification unit 37 may include, for example, a lamp, a speaker, or the like. Further, a display unit such as a liquid crystal display may be provided and displayed on the display unit. When the tape supply device 3 is configured to include a display unit such as a liquid crystal display, a so-called touch panel that inputs an operation by touching an image displayed on the display unit constitutes a part or all of the operation unit 36. You may.

Next, a reconnecting operation for reconnecting the standby adhesive tape Tpw to the supply adhesive tape Tps will be described. FIG. 11 is a flowchart showing the operation of supplying the adhesive tape by the tape supply device according to the present invention. FIG. 12 is a diagram showing a tape supply device in a state where the tape remaining amount of the first tape winding body stored in the first tape storage unit is exhausted. FIG. 13 is a diagram showing a tape supply device in a state where the standby adhesive tape is attached to the supply adhesive tape at the tape reconnection portion. FIG. 14 is a diagram showing a tape supply device when cutting the supply adhesive tape. FIG. 15 is a diagram showing a tape supply device when the standby adhesive tape is reconnected to the supply adhesive tape.

In the flowchart shown in FIG. 11, in the initial state, as shown in FIG. 3, the adhesive tape Tp drawn out from the first tape winding body Ra1 stored in the first tape storage unit 31 is the supply adhesive tape Tps. 2 The adhesive tape Tp drawn out from the second tape winding body Ra2 stored in the tape storage unit 32 is the standby adhesive tape Tpw.

In a state where the tape supply device 3 supplies the adhesive tape Tp to the tape sticking device 2, the control unit 35 is a tape storage unit in which the tape winding body supplying the supplied adhesive tape Tps is stored, 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 winding body Ra1 from the first remaining amount detection sensor 312 of the first tape accommodating unit 31 (step S101). The first remaining amount detection sensor 312 irradiates the first tape winding body Ra1 with light from the light source. When the remaining amount of the first tape winding body Ra1 is large, the light from the light source is blocked by the first tape winding body 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. Since the signal is an example, the signal is not limited to this, but the signal is switched or the signal is output when the remaining amount is exhausted.

Based on the information from the first remaining amount detection sensor 31, it is confirmed whether or not the remaining amount of tape of the first tape winding body Rs1 is sufficient to supply the tape (step S102). The remaining amount sufficient to supply the tape is, for example, the remaining amount of the first tape winding body Ra1 and the supply adhesive tape Tps arranged from the first tape storage portion 31 to the tape reconnecting portion 33. The total length of the tape feeding unit 4 may be longer than the length of the supplied adhesive tape Tps pulled out by the pulling-out operation of the tape feeding unit 4.

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

When the drawer roller 46 is in the second position P2 (Yes in step S104), the control unit 35 sends an instruction to the roller drive unit 47 to operate the roller drive unit 47 to move the drawer roller 46 to the first position P1. The withdrawal operation is executed (step S105). At this time, the supplied adhesive tape Tps is pulled out from the first tape winding body Ra1. After that, the process returns to the detection of the remaining amount of the first tape winding body Ra1 (step S101).

The control unit 35 can acquire the number of times the adhesive tape Tp is attached from the tape affixing device 2, and the length of the supplied adhesive tape Tps drawn out during the tape withdrawal operation is required by the affixing operation. In the case of an integral multiple (including 1 times) of the adhesive tape Tp to be formed, the control unit 35 may acquire the number of sticking operations instead of detecting the position of the pull-out roller 46 in step S103. Then, in step S104, it may be determined whether or not to perform the withdrawal operation based on the number of sticking operations since the previous withdrawal operation reaches a certain number of times.

Further, as shown in FIG. 12, when the remaining amount of the first tape winding body Ra1 is exhausted or is almost exhausted (No in step S102), the control unit 35 sends an instruction to the notification unit 37 and informs the user. The notification for connecting the standby adhesive tape Tpw to the supply adhesive tape Tps is executed (step S106). Here, the lamp is turned on and the notification is performed by voice.

In the tape reconnecting unit 33, there is a manual reconnection mode in which the standby adhesive tape Tpw is reconnected to the supply adhesive tape Tps when the user presses the tape exchange switch while the remaining amount of the tape winding is less than a certain amount. , The control unit 35 automatically reconnects 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, the reconnection is performed in a state where the length of the rear end of the supply adhesive tape Tps has a certain margin in order to reliably reconnect. On the other hand, in the manual connection mode, the user visually checks the length of the supplied adhesive tape Tps, and the user judges and reconnects the standby adhesive tape Tpw to the supplied adhesive tape Tps, so that 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, it is used by switching between the automatic reconnection mode, which causes some waste of adhesive tape but automatically reconnects, which is less troublesome for the user, and the manual reconnection mode, which is less wasteful of adhesive tape but requires more time and effort for the user. It is possible to do.

Then, the control unit 35 confirms whether or not it is currently in the manual connection mode (step S107). In the manual connection mode (Yes in step S107), the control unit 35 confirms whether or not the tape exchange switch 362 has been pressed (step S108). When the tape exchange switch 362 is not pressed (No in step S108), the control unit 35 determines that the user may further supply the adhesive tape Tps supplied from the first tape winding body Ra1. Recognizing and sending out the supplied adhesive tape Tps (step S103). Since the subsequent operations are the same as described above, they will be omitted.

Further, when the mode is not the manual connection mode (automatic connection mode) (No in step S107) or when the tape exchange switch 362 is pressed in the manual connection mode (Yes in step S108), the control unit. 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 portion 333 and the second holding plate portion 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 supply adhesive tape Tps arranged 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 supply 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, by attaching the tip end portion of the standby adhesive tape Tpw to the rear end portion of the supply adhesive tape Tps, the standby adhesive tape Tpw is connected to the rear end portion of the supply adhesive tape Tps. As a result, the supplied adhesive tape Tps is the second tape winding body Ra2 stored in the second tape storage unit 32 from the adhesive tape Tp pulled out from the first tape winding body Ra1 stored in the first tape storage unit 31. It is reconnected to the adhesive tape Tp pulled out from.

In the tape supply device 3, the timing at which the tape feeding unit 4 feeds the adhesive tape to the tape sticking device 2 and the timing at which the adhesive tape is pulled out from the tape winding body are different. That is, the tape feeding unit 4 does not pull out the adhesive tape from the tape winding body at the timing of feeding the adhesive tape to the tape sticking device 2. Then, at the timing when the control unit 35 and the tape feeding unit 4 are feeding out the tape, the standby adhesive tape is reconnected to the supply adhesive tape at the tape reconnecting unit. As a result, the tape supply device 3 can change the adhesive tape without stopping the supply of the tape. Further, since these timings are different, the tape feeding unit 4 does not perform the operation of peeling the adhesive tape from the tape winding body at the timing of feeding the adhesive tape, so that the tension of the adhesive tape to be fed is constant or substantially constant. It is possible to keep.

In other words, the control unit 35 prevents the operation instruction from being sent to each part of the tape reconnection unit 33 when, for example, the tape drive unit 47 of the tape delivery unit 4 is operating, and conversely, the tape reconnection unit 33. When each part of the above is operating, the adhesive tape can be reconnected without stopping the supply of the tape by operating with an algorithm that prevents the operation instruction from being sent to the tape drive unit 47 of the tape feeding unit 4. Is possible.

The tape reconnecting unit 33 reconnects the standby adhesive tape Tpw to the supply adhesive tape Tps by the above operation. Then, as shown in FIG. 15, a new tape winding body is stored as the first tape winding body Ra1, and the tip of the adhesive tape Tp pulled out from the first tape winding body Ra1 is held by the first holding plate portion 333. Therefore, the standby adhesive tape Tpw is used.

In the boxing device A, by using the tape supply device 3 according to the present invention, the tape winding body for supplying the adhesive tape is switched without stopping the supply of the adhesive tape. Therefore, unlike the conventional device, it is not necessary to stop the transfer device 1, that is, the production line for replacing the tape winding body.

In the tape supply device 3, the tape winding body is a consumable item and needs to be replaced. In the tape supply device 3, the first door 301 that opens and closes the first tape storage unit 31 and the second door 302 that opens and closes the second tape storage unit 32 when the tape is replaced can be individually opened and closed. Therefore, when one of the tape winding bodies of the first tape storage unit 31 and the second tape storage unit 32 is replaced, it is not necessary to stop the other. Therefore, in the tape supply device 3, the tape winding body can be replaced without stopping the supply of the adhesive tape. For this reason as well, the tact time can be shortened because the production line does not have to be stopped while the tape is replaced. As a result, the cost of the product can be reduced.

Further, during the box sealing operation, the tape winding body can be replaced without moving the tape supply device 2 with respect to the transfer device 1. Therefore, since a mechanism for moving the tape supply device 2 is not required, the configuration of the boxing device A can be simplified. Further, since the tape supply device 2 is not moved and the adhesive tape is supplied from the tape supply device 3 arranged outside the transport device 1, the degree of freedom in the layout of the boxing device A can be increased. It is possible.
