　従って、係合ピン68,69の頭部68b,69bを係合孔74,75の大径部74a,75aに挿入させ、ヘッド40全体を少し下降させることで、係合ピン68,69の軸部68a,69aが係合孔74,75の小径部74b,75bの底に着座される。着座後においては、係合ピンの頭部68b,69bが係合孔74,75の小径部74b,75bよりも大径であることから、頭部68b,69bが小径部74b,75bに引っ掛かり、着脱ユニット60のドック本体71からの抜け（落下）が防止される。また、両係合孔74,75は、対応する係合ピン68,69を、大径部74a,75aに同時挿入可能であると共に小径部74b,75bに同時係合可能な配置になっている。
　また、係合ピン68,69の軸部68a,69aが係合孔74,75の小径部74b,75bの底に着座された状態から、着脱ユニット60を上昇させて、係合ピン68,69の頭部68b,69bを係合孔74,75の大径部74a,75aに位置させると、その後、着脱ユニット60をドック本体71から離間させることで、着脱ユニット60をドック70から離脱させることができる。 The engagement holes 74 and 75 are holes through which the engagement pins 68 and 69 of the detachable unit 60 are engaged, and are rear surfaces (opposing surfaces) that are surfaces on one side of the rack plate 73 facing the mounted detachable unit 60. 2).
Each of the engagement holes 74 and 75 (see FIG. 9) includes a large diameter portion (large hole portion) 74a and 75a arranged on the upper side and a small diameter portion (small hole portion) 74b and 75b arranged on the lower side. It is a hole (8-shaped long hole) that overlaps each other. The diameters of the large diameter portions 74a and 75a are larger than the diameters of the heads (projecting portions) 68b and 69b of the engaging pins, and the head portions 68b and 69b can be inserted into the large diameter portions 74a and 75a. The diameters of the small diameter portions 74b and 75b are smaller than the diameters of the engaging pin head portions 68b and 69b and larger than the diameters of the engaging pin shaft portions 68a and 69a. Furthermore, the length of the shaft portions 68a and 69a of the engagement pin is slightly longer than the length of the engagement holes 74 and 75.
Therefore, the heads 68b and 69b of the engagement pins 68 and 69 are inserted into the large diameter portions 74a and 75a of the engagement holes 74 and 75, and the entire head 40 is slightly lowered, so that the shafts of the engagement pins 68 and 69 are reduced. The portions 68a and 69a are seated on the bottoms of the small diameter portions 74b and 75b of the engagement holes 74 and 75, respectively. After the seating, since the heads 68b, 69b of the engaging pins are larger in diameter than the small diameter parts 74b, 75b of the engaging holes 74, 75, the heads 68b, 69b are caught by the small diameter parts 74b, 75b, The removal (drop) of the detachable unit 60 from the dock body 71 is prevented. In addition, both the engagement holes 74 and 75 are arranged so that the corresponding engagement pins 68 and 69 can be simultaneously inserted into the large diameter portions 74a and 75a and can be simultaneously engaged with the small diameter portions 74b and 75b. .
Further, from the state in which the shaft portions 68a, 69a of the engaging pins 68, 69 are seated on the bottoms of the small diameter portions 74b, 75b of the engaging holes 74, 75, the detachable unit 60 is raised to engage the engaging pins 68, 69. When the heads 68b and 69b are positioned at the large diameter portions 74a and 75a of the engagement holes 74 and 75, the detachable unit 60 is then separated from the dock body 71 by separating the detachable unit 60 from the dock body 71. Can do.
　着脱ユニット保持磁石79は、ドック本体71に装着された着脱ユニット60の着脱ユニット本体61に当接する位置に設置されている。より具体的には、着脱ユニット保持磁石79は、２つの係合孔74,75のうち一方の保持アーム52の上方に配置された係合孔75と同じ高さであって、他方の保持アーム51の上方であり、着脱ユニット本体61に当接する位置に設置されている。従って、ドック本体71に着脱ユニット60を装着すると、この着脱ユニット保持磁石79によって着脱ユニット本体61が引き付けられ、２つの係合孔74,75および着脱ユニット保持磁石79による三ヶ所で支持され、着脱ユニット60がドック本体71により確実に保持される。
　また、着脱ユニット60の重心に近い部分と対向する位置に着脱ユニット保持磁石79を設置したので、ヘッド本体41に着脱ユニット60を装着した後、当該着脱ユニット60をドック本体71から離間させるとき、着脱ユニット60をドック本体71からスムーズに離間させることができる。 The detachable unit holding magnet 79 is installed at a position where it comes into contact with the detachable unit body 61 of the detachable unit 60 mounted on the dock body 71. More specifically, the detachable unit holding magnet 79 has the same height as the engaging hole 75 disposed above one holding arm 52 out of the two engaging holes 74 and 75, and the other holding arm. It is located above 51 and at a position where it comes into contact with the detachable unit main body 61. Therefore, when the detachable unit 60 is attached to the dock body 71, the detachable unit main body 61 is attracted by the detachable unit holding magnet 79, and is supported at three places by the two engagement holes 74 and 75 and the detachable unit holding magnet 79. The unit 60 is securely held by the dock body 71.
Also, since the detachable unit holding magnet 79 is installed at a position facing the portion near the center of gravity of the detachable unit 60, when the detachable unit 60 is separated from the dock body 71 after the detachable unit 60 is mounted on the head body 41, The detachable unit 60 can be smoothly separated from the dock main body 71.
　支持アーム76aは、ドック本体71の他方端部側に構成され、他方端部から下方に延びて所定の形状に形成された板状の部材であり、その先端に形成されたテープ仮留め面（テープ位置決め部）76を備えている。そして、テープ仮止め面76は、上流側押しローラ65よりもテープ送り経路Trの下流側になるように配置されており、テープ吸引部67にテープＴが吸着保持された状態でのテープ送り経路Trの延長線上に配置されている。つまり、ドック70の着脱ユニット60に新規のロールRを取り付けたときは、ロールRからテープTの先端を引き出してテープ吸引部67の吸引力によりテープTの保持及びガイドが可能になるように、このテープ仮留め面76に貼り付ける。 The support arm 76a is a plate-like member that is formed on the other end side of the dock main body 71, extends downward from the other end portion, and has a predetermined shape. Tape positioning part) 76 is provided. The tape temporary fixing surface 76 is disposed downstream of the upstream pushing roller 65 in the tape feeding path Tr, and the tape feeding path in a state where the tape T is sucked and held by the tape suction portion 67. It is arranged on the extension line of Tr. That is, when a new roll R is attached to the detachable unit 60 of the dock 70, the tip of the tape T is pulled out from the roll R so that the tape T can be held and guided by the suction force of the tape suction portion 67. Affixed to the tape temporary fixing surface 76.
　開口部77は、ドック本体71の対向面とは反対側の面に、着脱ユニット支持部と係合部の係合領域に臨む位置に形成されている。別の言い方をすれば、開口部77は、ドック本体71の、着脱ユニット支持部と係合部の係合領域を含む範囲に開口形成されている。より具体的には、開口部77は、ドック本体71に着脱ユニット60を装着するとき、テープホルダ64、テープホルダ64に装着されたロールR及びガイドローラ66a,66bと、ドック本体71との干渉を防止できる位置及び範囲に形成されている。従って、着脱ユニット60をドック本体71に保持させるとき、着脱ユニット60を容易、迅速且つ確実にドック本体71に引っ掛けて保持させることができる。また、着脱ユニット60がドック本体71に保持された状態で、着脱ユニット60のテープホルダ64やこれに装着されたロールRを、開口部77越しにドック本体71の背面側から視認することができ、また、テープホルダ64やロールRに対してアクセスすることができる。つまり、ヘッド本体41からドック本体71に自動的に受け渡された状態の着脱ユニット60のテープホルダ64に対して、ドック本体71の背面側から、そのままの状態（懸架した状態）でロール交換作業を行うことができる。 The opening 77 is formed on the surface opposite to the facing surface of the dock main body 71 at a position facing the engaging region of the detachable unit support portion and the engaging portion. In other words, the opening 77 is formed in a range of the dock body 71 including the engagement region between the detachable unit support portion and the engagement portion. More specifically, when the detachable unit 60 is attached to the dock body 71, the opening 77 is an interference between the tape holder 64, the roll R and guide rollers 66a and 66b attached to the tape holder 64, and the dock body 71. It is formed in the position and range which can prevent. Therefore, when the detachable unit 60 is held on the dock body 71, the detachable unit 60 can be hooked and held on the dock body 71 easily, quickly and reliably. Also, with the detachable unit 60 held by the dock body 71, the tape holder 64 of the detachable unit 60 and the roll R attached thereto can be viewed from the back side of the dock body 71 through the opening 77. In addition, the tape holder 64 and the roll R can be accessed. In other words, for the tape holder 64 of the detachable unit 60 that has been automatically transferred from the head body 41 to the dock body 71, the roll replacement work is performed as it is (suspended) from the back side of the dock body 71. It can be performed.
　ドック本体保持機構78は、着脱ユニット交換位置（図１３のドック本体位置参照）に移動されたドック本体71をこの位置に保持する手段であり、架台72ｍに設置された第１保持磁石78a（図９参照）と、ドック本体の背面側に設置された第２保持磁石78b（図１１参照）と、架台72mの背面側に設置された第1ストッパ78c（図１１参照）と、ドック本体71の一方端部に設置されたカバー71c（図９参照）と反対側のドック本体７１の他方端部に設置された第２ストッパ78dで構成されている。
　第１保持磁石78a（図９参照）は、ドック本体71がロール交換作業位置（図９のドック本体位置参照）に位置されたとき、第２ストッパ78dに当接して引き付け保持できる位置に設置されている。また、第２保持磁石78b及びストッパ78c（図１１参照）は、ドック本体71が着脱ユニット交換位置に位置されたときに相互に当接できる配置で設置されている。
　従って、ドック本体71が着脱ユニット交換位置(図13のドック本体位置参照)に移動されると、第２保持磁石78bによって第2ストッパ78cが引き付けられ、ドック本体71が着脱ユニット交換位置に確実に保持される。また、ドック本体71がロール交換位置(図14のドック本体位置参照)に移動されると、第１保持磁石78aによってドック本体71がロール交換位置に確実に保持される。 The dock body holding mechanism 78 is means for holding the dock body 71 moved to the detachable unit replacement position (see the dock body position in FIG. 13) at this position, and the first holding magnet 78a (see FIG. 9), a second holding magnet 78b (see FIG. 11) installed on the back side of the dock body, a first stopper 78c (see FIG. 11) installed on the back side of the mount 72m, and the dock body 71 A cover 71c (see FIG. 9) installed at one end portion and a second stopper 78d installed at the other end portion of the dock body 71 on the opposite side.
The first holding magnet 78a (see FIG. 9) is installed at a position where it can be in contact with and attracted to the second stopper 78d when the dock body 71 is positioned at the roll replacement work position (see the dock body position in FIG. 9). ing. Further, the second holding magnet 78b and the stopper 78c (see FIG. 11) are disposed in such a manner that they can come into contact with each other when the dock body 71 is located at the detachable unit replacement position.
Therefore, when the dock main body 71 is moved to the detachable unit replacement position (see the dock main body position in FIG. 13), the second stopper 78c is attracted by the second holding magnet 78b, so that the dock main body 71 is securely in the detachable unit replacement position. Retained. When the dock main body 71 is moved to the roll replacement position (see the dock main body position in FIG. 14), the dock main body 71 is securely held at the roll replacement position by the first holding magnet 78a.
　コントローラＣは、図７に示されるように、ヘッド移動機構37やテープ吸引部67等の動作制御対象に信号線を介して接続されており、これらの制御対象との間で制御信号の送受信が可能になっている。そして、コントローラＣは、ヘッド移動機構37やテープ吸引部67等によるテープ貼付動作や着脱ユニット交換動作の制御を実行する。なお、ヘッド移動機構37は、フレーム10の移動バー32の左右方向への移動、ヘッド支持部材34の前後方向への移動及び昇降部材36の上下動を行ってヘッド40を移動させるための移動機構の総称である。本実施例のヘッド移動機構37は、直交移動機構を採用したが、その他のヘッド移動機構としては、複数のアームから構成される多関節移動機構を採用してもよい。また、制御信号の送受信方法は周知の方法であるので、ここではその詳細な説明を省略する。 As shown in FIG. 7, the controller C is connected to operation control targets such as the head moving mechanism 37 and the tape suction unit 67 via signal lines, and control signals can be transmitted to and received from these control targets. It is possible. Then, the controller C controls the tape application operation and the detachable unit replacement operation by the head moving mechanism 37, the tape suction unit 67, and the like. The head moving mechanism 37 is a moving mechanism for moving the head 40 by moving the moving bar 32 of the frame 10 in the left-right direction, moving the head support member 34 in the front-rear direction, and moving the elevating member 36 up and down. It is a general term. The head moving mechanism 37 of the present embodiment employs an orthogonal moving mechanism, but as another head moving mechanism, an articulated moving mechanism composed of a plurality of arms may be employed. Further, since the control signal transmission / reception method is a well-known method, detailed description thereof is omitted here.
　次に、テープ貼付装置においてテープ貼付動作中に自動的に実行されるテープ交換動作を図８、図９及び図１３から図１５を用いて説明する。 Next, the tape exchanging operation automatically executed during the tape applying operation in the tape applying device will be described with reference to FIGS. 8, 9 and 13 to 15.
　テープ交換動作を実行する場合は、その前に、次に説明する着脱ユニット準備作業を完了させる。
　着脱ユニット準備作業では、２つのドック70のうち一方のドック70を、空の状態のままロール着脱位置に位置させる。そして、他方のドック70の把持部71ｈを持ち、ドック本体41をロール着脱位置（図９参照）に移動させる。この状態で、ドック本体41に、新しいロールRが装着された着脱ユニット60を保持させた状態にする（図１４参照）。このとき、新たなロールRが装着された着脱ユニット60を他方のドック本体71に新規に保持させてもよいし、既に保持された状態の着脱ユニット60のテープホルダ64に新たなロールRを装着しても良い。
　そして、他方のドック70の着脱ユニット60に装着されたロールＲからテープＴを引き出し、テープ送り経路Trに沿って掛け回し、弛みがない状態でテープ先端をテープ仮留め面76に貼り付ける（図６参照）。
　その後、ドック本体41を着脱ユニット交換位置（係脱位置、図１３参照）に移動させると、ドック本体保持機構78によってドック本体71が着脱ユニット交換位置に保持され、着脱ユニット準備作業が完了する。 Before executing the tape exchange operation, the detachable unit preparation operation described below is completed.
In the attachment / detachment unit preparation work, one of the two docks 70 is positioned at the roll attachment / detachment position in an empty state. And the holding part 71h of the other dock 70 is held, and the dock main body 41 is moved to the roll attaching / detaching position (see FIG. 9). In this state, the dock main body 41 is made to hold the detachable unit 60 to which the new roll R is mounted (see FIG. 14). At this time, the attaching / detaching unit 60 to which the new roll R is attached may be newly held by the other dock body 71, or the new roll R is attached to the tape holder 64 of the attaching / detaching unit 60 already held. You may do it.
Then, the tape T is pulled out from the roll R mounted on the attachment / detachment unit 60 of the other dock 70, is hung along the tape feed path Tr, and the tip of the tape is attached to the temporary tape fastening surface 76 without any slack (see FIG. 6).
Thereafter, when the dock body 41 is moved to the detachable unit replacement position (engagement / disengagement position, see FIG. 13), the dock body 71 is held at the detachable unit replacement position by the dock body holding mechanism 78, and the detachable unit preparation work is completed.
　このような着脱ユニット準備作業が完了した状態で、テープ貼付動作中のテープ貼付装置１のテープＴがなくなると、次のようなテープ交換動作が自動的に実行される。
　なお、テープ交換動作では、ヘッド移動機構37がヘッド40やヘッド本体41を移動させる係脱移動手段として用いられる。ヘッド移動機構37は、上述したように、ヘッド40を前後、左右及び上下方向に移動可能であり、ヘッド40やヘッド本体41に装着された着脱ユニット60を、ドック本体41の前面と平行な面における任意の方向（Y方向及びZ方向）に移動させることができる。 When the tape T of the tape applicator 1 during the tape applicating operation is exhausted in a state where such a detachable unit preparation operation is completed, the following tape exchanging operation is automatically executed.
In the tape exchange operation, the head moving mechanism 37 is used as an engagement / disengagement moving means for moving the head 40 or the head main body 41. As described above, the head moving mechanism 37 can move the head 40 back and forth, left and right, and up and down, and the detachable unit 60 mounted on the head 40 and the head main body 41 can be connected to a surface parallel to the front surface of the dock main body 41. Can be moved in any direction (Y direction and Z direction).
　テープ交換動作は、概略的には、テープが無くなったヘッド40をドック70に移動させるヘッド戻しステップと、テープが無くなった着脱ユニット60をヘッド本体41から取外す着脱ユニット取外しステップと、新しいテープが装着された状態の着脱ユニット60をヘッド本体41に装着する着脱ユニット装着ステップと、新しいテープTが装着されたヘッド40をテープ貼付作業位置に移動させるヘッド出動ステップとを備えている。 In general, the tape replacement operation consists of a head return step for moving the head 40 with no tape to the dock 70, a detachment unit removal step for removing the detachable unit 60 with the tape removed from the head body 41, and a new tape. An attachment / detachment unit attachment step for attaching the attachment / detachment unit 60 to the head main body 41 and a head moving step for moving the head 40 attached with the new tape T to the tape application work position are provided.
　ヘッド戻しステップでは、まず、貼付作業位置でテープ貼付動作を行っていたヘッド40を一方のドック（空のドック）70の着脱ユニット係脱位置に向けて移動させる。図１２に示される状態は、着脱ユニット係脱位置に移動される直前のヘッド40の状態である。この状態からヘッド40をさらにドック本体71側に移動させると、まず、係合ピン68,69が係合孔74,75に挿入され、次に、着脱ユニット60の前面（ドック本体71との対向面）がドック本体71のラック板73の後面（着脱ユニット60との対向面）に当接する。また、同時に、着脱ユニット保持磁石（着脱ユニット保持機構）79が着脱ユニット本体61を引き付けた状態になる。その後、ヘッド40を下降させて、係合ピン68,69を係合孔74,75の小径部74b,75bに係合させる。 In the head return step, first, the head 40 that has been performing the tape application operation at the application work position is moved toward the attachment / detachment unit attachment / detachment position of one dock (empty dock) 70. The state shown in FIG. 12 is the state of the head 40 immediately before being moved to the detachable unit engaging / disengaging position. When the head 40 is further moved to the dock body 71 from this state, the engagement pins 68 and 69 are first inserted into the engagement holes 74 and 75, and then the front surface of the detachable unit 60 (opposite the dock body 71). Surface) comes into contact with the rear surface of the rack plate 73 of the dock body 71 (the surface facing the detachable unit 60). At the same time, the detachable unit holding magnet (detachable unit holding mechanism) 79 attracts the detachable unit main body 61. Thereafter, the head 40 is lowered, and the engagement pins 68 and 69 are engaged with the small diameter portions 74b and 75b of the engagement holes 74 and 75, respectively.
　続く着脱ユニット取外しステップでは、まず、ヘッド本体41の保持アーム51,52を作動させて、棒体51b,52bを前進移動させると共に爪51c,52cが下向きになるように回転させる。これにより、ヘッド本体41による着脱ユニット60の保持状態が解除され、着脱ユニット60が係合孔74,75と着脱ユニット保持磁石79とによってドック本体71に保持される。その後、ヘッド40をドック本体71から離間させると、ヘッド40からの着脱ユニット60の取外しが完了する。 In the subsequent detachable unit removal step, first, the holding arms 51 and 52 of the head body 41 are operated to move the rods 51b and 52b forward and rotate the claws 51c and 52c downward. As a result, the holding state of the detachable unit 60 by the head body 41 is released, and the detachable unit 60 is held by the dock body 71 by the engagement holes 74 and 75 and the detachable unit holding magnet 79. Thereafter, when the head 40 is separated from the dock body 71, the removal of the detachable unit 60 from the head 40 is completed.
　続く着脱ユニット装着ステップでは、まず、取り外された着脱ユニット60を保持している一方のドック本体71から離間されたヘッド本体41を、他方のドック70の着脱ユニット係脱位置に移動させる。このとき、ヘッド本体41のフロント板43の位置決め穴45a,45bに、他方のドック70の着脱ユニット60の背面の位置決めピン63a,63bが挿入されるように、ヘッド本体41を移動させる。そして、ヘッド本体41の保持アーム51,52を保持動作させ着脱ユニット60を保持する。その後、着脱ユニット60の吸引部67を作動させる。これにより吸引部67の吸引面67aにテープTが吸着される。また、カッター部46の刃48を進出移動させて、テープ仮留め面76に貼り付けられたテープ先端部とテープTのロールR側とを切断する。
　その後、ヘッド40を上昇させることにより、ヘッド本体41に新たに装着された着脱ユニット60の係合ピン68,69を係合孔74,75の大径部74a,75aに位置させ、ヘッド40をドック本体71から離間させる。先のテープ切断動作によって、テープロールR側とテープ先端部とが切断されているので、この離間動作のときにロールRからテープが無駄に引き出されることが防止される。これにより、ヘッド本体41への着脱ユニットの装着が完了した状態になる。 In the subsequent attaching / detaching unit mounting step, first, the head body 41 separated from the one dock body 71 holding the detached attaching / detaching unit 60 is moved to the attaching / detaching unit engaging / disengaging position of the other dock 70. At this time, the head body 41 is moved so that the positioning pins 63a and 63b on the back surface of the detachable unit 60 of the other dock 70 are inserted into the positioning holes 45a and 45b of the front plate 43 of the head body 41. Then, the holding arms 51 and 52 of the head body 41 are held and the detachable unit 60 is held. Thereafter, the suction part 67 of the detachable unit 60 is operated. As a result, the tape T is adsorbed to the suction surface 67a of the suction part 67. Further, the blade 48 of the cutter unit 46 is moved forward to cut the tape front end portion affixed to the tape temporary fixing surface 76 and the roll R side of the tape T.
Thereafter, by raising the head 40, the engagement pins 68, 69 of the detachable unit 60 newly attached to the head body 41 are positioned at the large diameter portions 74a, 75a of the engagement holes 74, 75, and the head 40 is moved. Separate from the dock body 71. Since the tape roll R side and the leading end of the tape are cut by the previous tape cutting operation, the tape is prevented from being unnecessarily drawn from the roll R during the separation operation. Thereby, the attachment of the detachable unit to the head main body 41 is completed.
　続くヘッド復帰ステップでは、新しいテープTが装着されたヘッド40をテープ貼付作業位置に移動させ、ヘッド40によるテープ貼付動作を再開させる。 In the subsequent head return step, the head 40 with the new tape T is moved to the tape application work position, and the tape application operation by the head 40 is resumed.
　本実施例においては、２つのドック70による交換動作を記載したが、１つのドック70による交換動作においては、ヘッド40から着脱ユニット60を着脱ユニット係脱位置に待機する空のドック70へ懸架させる。その後、ドック70をテープ交換位置に移動し、テープ交換を行う。テープ交換を行っている最中は、ヘッド40を着脱ユニット60の装着装脱前の位置に待機させておき、テープ交換完了後、ドック70が着脱ユニット係脱位置に位置づけられると、所定の信号(例えば、装着開始信号)により着脱ユニット装着ステップを行う。 In this embodiment, the exchange operation by the two docks 70 has been described, but in the exchange operation by one dock 70, the detachable unit 60 is suspended from the head 40 to the empty dock 70 waiting at the detachable unit engaging / disengaging position. . Thereafter, the dock 70 is moved to the tape exchange position, and the tape is exchanged. While the tape is being exchanged, the head 40 is kept waiting at the position before the attachment / detachment of the attachment / detachment unit 60, and after the tape exchange is completed, when the dock 70 is positioned at the attachment / detachment unit attachment / detachment position, a predetermined signal is displayed. The detachable unit mounting step is performed according to (for example, a mounting start signal).
　このように、本実施例のテープ貼付装置では、上述した着脱ユニット準備作業を予め行っておくことにより、ヘッド40のテープがなくなったとき、自動的にロール交換を実行させることができる。ロール交換動作が全て自動であるので、ロール交換が迅速であり、ロール交換作業効率が向上する。また、自動によるテープ貼付作業を継続して行うことができるので、上流工程から下流工程における作業に影響を与えることなく全体的な作業を継続して行うことができる。また、ロール交換作業効率が向上することで、テープ貼付装置のテープ貼付動作効率を向上させることができる。
　なお、上述した着脱ユニット準備作業は、作業者によって行われる作業であるが、自動的に行われるテープ交換動作の合間に簡単に行うことができる作業である。従って、作業者による着脱ユニット準備作業があるからといって、自動的に行われるテープ交換作業効率が低下することはない。また着脱ユニット準備作業は簡単な作業であるので自動的に行うことも可能である。 Thus, in the tape sticking apparatus of the present embodiment, roll replacement can be automatically executed when the tape of the head 40 is exhausted by performing the above-described detachable unit preparation work in advance. Since the roll exchange operation is all automatic, the roll exchange is quick and the roll exchange work efficiency is improved. Moreover, since the tape sticking operation by the automatic operation can be continuously performed, the entire operation can be continuously performed without affecting the operations from the upstream process to the downstream process. Moreover, the tape sticking operation efficiency of the tape sticking device can be improved by improving the roll exchanging work efficiency.
The above-described attachment / detachment unit preparation operation is an operation performed by an operator, but can be easily performed between automatic tape replacement operations. Therefore, even if there is a work for preparing the detachable unit by the operator, the efficiency of the tape exchange work that is automatically performed does not decrease. The detachable unit preparation work is a simple work and can be automatically performed.
