The present invention relates to a tape processing equipment that performs predetermined processing on the adhesive tape having an adhesive layer and a separation material layer.

  2. Description of the Related Art Conventionally, a tape processing apparatus that performs a predetermined process on an adhesive tape including an adhesive layer and a release material layer is known (see, for example, Patent Document 1). This tape processing apparatus (tag label producing apparatus) performs printing on the adhesive tape while conveying the adhesive tape (tag tape) provided with the adhesive layer (adhesive layer) and the release material layer (release paper).

  That is, in this tape printer, an adhesive tape roll (tag tape roll body) around which an adhesive tape is wound is used by being attached to a tape holder storage portion of a casing (main body casing). And if an adhesive tape roll is attached to a tape holder accommodating part, an adhesive tape will be drawn | fed out and conveyed by rotation of the said adhesive tape roll. By forming a desired print on the conveyed adhesive tape, an adhesive tape with print is generated and cut. At the time of use, the release material layer is peeled off by the user from the cut adhesive tape with print. And it sticks on the appropriate sticking object which a user intends using the adhesive force of the adhesive layer exposed by peeling of a peeling material layer.

JP 2006-159413 A

  When the release material layer is peeled off from the adhesive tape at the time of use as described above, a peeling portion for peeling the release material layer from the adhesive tape is provided from the viewpoint of improving the handleability by the user. By winding the release material layer peeled off at the peeling part, the release material layer is also rolled in the same manner as the adhesive tape, and these two rolls (adhesive tape roll and release material roll) are incorporated as one tape cartridge. Can be considered. In this case, the two rolls are in a non-rotatable state in the state of the tape cartridge alone before being attached to the housing, and the two rolls are in a freely rotatable state when the tape cartridge is attached in the housing. There is a need.

  However, simply by allowing the two rolls to rotate freely when the tape cartridge is mounted on the casing, the release material roll rotates when the tape cartridge is mounted on the casing. Normal when the adhesive tape peeling branch point (the point where the integral adhesive tape bifurcates into the release material and the other tape) deviates from the position of the peeling portion, and then the conveyance starts. There is a possibility that the proper peeling operation cannot be performed.

An object of the present invention is to provide a tape processing equipment that can only separation material roll to avoid peeling operation occurrence of the failure due to rotating peeling branch point is shifted.

In order to achieve the above object, the present invention provides an adhesive tape comprising a casing constituting the outer shell of the apparatus, an adhesive layer and a release material layer covering the adhesive layer, around a first axis in a substantially horizontal direction. A wound adhesive tape roll, a release material roll for winding the release material layer peeled off from the adhesive tape fed out and conveyed from the adhesive tape roll, around a second axis in a substantially horizontal direction, and An adhesive tape roll and the release material roll are provided so as to be connected, and the adhesive tape roll is rotatably supported on one side and the release material roll is rotatably supported on the other side, and the adhesive tape A tape cover having a connecting arm having a peeling portion for peeling off the release material layer from the adhesive tape fed out from a roll and conveyed, and attached to the housing. A first storage portion that is provided on the one side of the housing and receives the adhesive tape roll from above when the tape cartridge is mounted and stores the first axis in a horizontal direction; A transport roller for transporting the adhesive tape fed from the adhesive tape roll stored in one storage section in a tape orientation with the tape width direction as a horizontal direction; and the tape cartridge provided on the other side of the housing And a second storage section that receives the release material roll from above and stores the second axis in a horizontal state when the tape cartridge is mounted, wherein the tape cartridge is a first externally mounted tape cartridge. When the operation force is not input, the adhesive tape roll supported on the one side of the connecting arm is in a non-rotatable locked state, and the first operation is performed. The adhesive tape roll is switched to an unlocked state in which the adhesive tape roll can be freely rotated at the time of input, and the release material roll supported on the other side of the connecting arm at the time of non-input of the second operating force from the outside. A second locking member that switches the release material roll to a rotatable unlocked state when the second operating force is input while being in a non-rotatable locked state, and the housing includes the first locking member And applying the first operating force to the unlocked state of the first locking member, and then applying the second operating force to the second locking member to the cause the switching to the unlock state, have a unlock switching means, said unlocking switch means received from above the first receiving portion when mounting the tape cartridge A first convex portion provided in the first storage portion so as to protrude toward the adhesive tape roll to be inserted, and applying the first operating force to the first lock member at the time of reception, and mounting of the tape cartridge A second protrusion that is provided in the second storage portion so as to protrude to the side of the release material roll that is sometimes received from above into the second storage portion, and that applies the second operating force to the second lock member during the reception. has a section, a, so that the second projecting portion at the timing after the first protrusion gave the first operating force providing the second operating force, characterized that you have configured .

  In the present invention, the tape cartridge is an adhesive tape roll wound with an adhesive tape provided with an adhesive layer and a release material layer, a release material roll wound with the release material layer, and these two rolls are rotatable. And a connecting arm to support. When the tape cartridge is mounted on the casing, the adhesive tape roll is stored in the first storage section on one side of the casing, and the release material roll is stored in the second storage section on the other side of the casing. When the transport roller is driven, the pressure-sensitive adhesive tape fed out by the rotation of the pressure-sensitive adhesive tape roll is transported and transported to the position where the peeling is performed (the peeling portion of the connecting arm), and the peeling material layer is formed at the peeling portion. Is torn off. The release material layer thus peeled is introduced into the second storage portion and wound, whereby the release material roll is formed.

  By the way, since the connecting arm rotatably supports the adhesive tape roll and the release material roll, in the state of the tape cartridge alone before being attached to the housing as described above, each roll can freely rotate as it is. The tape breaks out. On the other hand, when the tape cartridge is mounted on the housing, each roll must be freely rotated in order to perform the above-described transport.

  In the present invention, using the first lock member and the second lock member, before the tape cartridge is mounted on the housing as described above, the adhesive tape roll and the release material roll are respectively brought into a non-rotatable locked state. Further, when the tape cartridge is mounted on the housing, the adhesive tape roll and the release material roll are each switched to a freely unlocked state. Thereby, the above conveyance can be performed smoothly.

  At this time, the adhesive tape roll and the release material roll in the unlocked state are attached to the first storage portion and the second storage portion, respectively, and the transport in the tape cartridge is caused by a transport roller coming into contact with the adhesive tape. Some force is applied to the adhesive tape already in the path. As a result, as it is, the adhesive tape roll or the release material roll that is rotatable in the unlocked state is dragged by the force applied to the adhesive tape, and the conveyance roller is actually rotationally driven to start conveyance. Turn slightly before).

  When the adhesive tape roll rotates, the adhesive tape slightly sags in the vicinity of the feeding position from the adhesive tape roll because the conveyance roller rotates in the same forward direction as when the conveyance is actually started. Only. As a result, the sag is eliminated at the start of the rotation driving by the transport roller, and there is no problem because the state is shifted to a normal transport state. However, when the release material roll rotates, the release material wound around the release material roll is peeled off because the rotation is in the direction opposite to the direction when the release material layer is actually peeled off and wound up. It will run backwards toward the club. However, even if the release material is returned in this way, it has already been peeled off, so that it will not be integrated with the tape before peeling. That is, the tearing branch point (the point where the integral adhesive tape is bifurcated into the release material and the other tape) that has occurred before the reverse running only moves back upstream in the transport direction. In this case, the peeling branch point of the adhesive tape deviates from the position of the peeling portion set as the part where the peeling is performed on the connecting arm. As a result, there is a possibility that normal peeling operation cannot be performed when the transport roller is rotated and the transport is started.

  Therefore, in the present invention, the unlock switching means provided in the housing controls the switching timing of the first lock member and the second lock member to the unlock state. That is, after the first operating force is applied to the first lock member to switch to the unlocked state, the second operating force is applied to the second lock member to switch to the unlocked state. Thereby, after an adhesive tape roll becomes rotatable previously, a peeling material roll becomes rotatable. As a result, at least the above-described peeling operation failure due to the rotation of only the release material roll and the deviation of the peeling branch point can be avoided.

  According to the present invention, it is possible to avoid the occurrence of a peeling operation failure due to the rotation of only the peeling material roll and the separation of the branching point.

I have. An engagement piece portion that protrudes outward in the radial direction on the radially outer surface of the annular portion 55 on the distal end side of each extension portion 56 and can be engaged with the engagement recess 54 of the second core member 50. 56a is provided.

  As shown in FIG. 9A, the second engagement member L2 is inserted into the hollow portion 51b of the second core member 50 from the right side of the second bracket portion 24 on the right side, and is substantially horizontal ( In detail, the engagement piece 56a is engaged with the second core member 50 as shown in FIG. 9 (b) by moving to the left) (pressed to the position shown in FIG. 9 (b)). The second roll R2 is brought into the locked state by meshing with and engaged with the recess 54. Further, the second engaging member L2 has a force (second operating force, hereinafter simply referred to as “second operating force”) that moves leftward from the outside in a state where the second roll R2 is locked. As shown in FIG. 9C, the engagement of the second core member 50 of the engagement piece 56a is performed by being given and moved to the left (pressed to the position shown in FIG. 9C). The engagement with the recess 54 is released, and the second roll R2 is brought into the unlocked state. That is, the second engagement member L2 locks the second roll R2 when the second operating force is not input from the outside, and unlocks the second roll R2 when the second operating force is input from the outside. Switch to.

  At this time, as shown in FIG. 10, the first storage portion 5 protrudes to the first roll R1 side that is received from above when the adhesive tape cartridge TK is mounted at the first predetermined position 8, that is, substantially upward. Thus, the 1st convex part 5a (a part of inner wall of the housing | casing 2 in this example) is provided. When the first roll R1 is received in the first storage part 5, the first convex part 5a is brought into contact with the annular part 35 of the first engagement member L1 fixed to the first roll R1. By pressing the ring portion 35 leftward, the first operating force is applied to the first engagement member L1.

  Further, at this time, the second storage portion 7 has a second protrusion so as to protrude to the second roll R2 side that is received from above when the adhesive tape cartridge TK is mounted at the first predetermined position 8, that is, substantially upward. A portion 7a (in this example, a part of the inner wall of the housing 2) is provided. The second convex portion 7a is brought into contact with the annular portion 55 of the second engagement member L2 fixed to the second roll R2 when the second roll R2 is received in the second storage portion 7, and the circle By pressing the ring portion 55 leftward, the second operating force is applied to the second engagement member L2.

  Here, when the adhesive tape cartridge TK is mounted, the unlocked first roll R1 and second roll R2 are accommodated in the first accommodating portion 5 and the second accommodating portion 7, respectively, and the adhesive tape 150 to be printed is used. A slight force is applied to the adhesive tape 150 to be printed that is already extended in the tape conveyance path in the adhesive tape cartridge TK due to the contact of the conveyance roller 11 and the like. As a result, as it is, the first roll R1 and the second roll R2 that are rotatable in the unlocked state are dragged by the force applied to the print adhesive tape 150 (actually, the transport roller 11 is rotationally driven). Slightly rotates (before transport starts).

  When the first roll R1 rotates, the rotation is the same forward direction (A direction in FIGS. 2 and 3) as when the conveyance roller 11 is actually driven to rotate and the conveyance is started. The printed adhesive tape 150 is only slightly slackened in the vicinity of the feeding position from the roll R1. As a result, the sag is eliminated with the start of the rotation drive by the transport roller 11, and there is no problem because the state is shifted to a normal transport state. However, when the second roll R2 is rotated, the rotation is in the direction opposite to the direction (C direction in FIGS. 2 and 3) when the release material layer 151 is actually peeled off and wound. The release material layer 151 taken up by the two rolls R <b> 2 will run backward toward the peeling portion 13. However, even if the release material layer 151 is returned in this way, it has already been peeled off, so it will not be integrated with the printed adhesive tape 150 ′ before peeling. That is, the peeling branching point (the point where the integral printed adhesive tape 150 ′ is bifurcated into the release material layer 151 and the printed adhesive tapes 152 and 153) before the reverse running is upstream in the tape conveying direction. It only moves back in time. In this case, the peeling branch point of the printed adhesive tape 150 ′ deviates from the position of the peeling portion 13 that is set as the part to be peeled off in the connecting arm 21. As a result, when the transport roller 11 is subsequently rotated and transport is started, there is a possibility that a normal peeling operation cannot be performed.

  Therefore, in the present embodiment, as shown in FIG. 10, the height direction position of the upper end portion of the first convex portion 5a in the housing 2 is higher than the height direction position of the upper end portion of the second convex portion 7a. The distance h is increased, and when the adhesive tape cartridge TK is mounted, the second convex portion 7a is second when the first convex portion 5a applies the first operating force to the first engaging member L1. By configuring so as to apply the second operating force to the engaging member L2, the switching timing of the first engaging member L1 and the second engaging member L2 to the unlocked state is controlled. That is, when the adhesive tape cartridge TK is mounted, the first engagement member L1 first switches the first roll R1 to the unlocked state by the first operating force by the first recess 5a, and then the second operation is performed. Switching to the unlocked state of the second roll R2 by the second engaging member L2 is performed by the second operating force applied to the second engaging member L2 by the recess 7a. Thereby, after the 1st roll R1 becomes rotatable previously, the 2nd roll R2 becomes rotatable, and the above conveyance can be performed smoothly. In addition, the said 1st convex part 5a and the 2nd convex part 7a comprise the unlock switching means of each claim.

  Here, when the adhesive tape cartridge TK is mounted (specifically, when the first roll R1 is switched to the unlocked state), the first engagement member L1 fixed to the first bracket portion 22 on the right side is The first operating force is applied to the first engagement member L1 by being pressed leftward while being in contact with the first convex portion 5a of the first storage portion 5. As a result, the first bracket 22 on the right side is pushed to the left side by the first operating force (force to move to the left) and is bent to the left side, thereby the first bracket on the right side. The part 22 may be deformed. Similarly, when the adhesive tape cartridge TK is mounted (specifically, when the second roll R2 is switched to the unlocked state), the second engaging member L2 fixed to the right second bracket portion 24 is used. However, the second operating force is applied to the second engagement member L2 by being pressed leftward while being in contact with the first convex portion 6a of the second storage portion 6. As a result, the second bracket 24 on the right side is pushed to the left side by the second operating force (force to move to the left), and the left side second bracket is bent. The part 24 may be deformed.

  Therefore, in the present embodiment, as shown in FIGS. 7, 10, and 11, the first protrusion 90 is provided at the lower portion on the right side of the first storage portion 6, and the first bracket portion 22 on the right side. A first locking portion 91 is provided at the lower end portion of the second storage portion 7, a second projecting portion 92 is provided at the lower portion on the right side of the second storage portion 7, and a second projection portion 92 is provided at the lower end portion of the second bracket portion 24 on the right side. Two locking portions 93 are provided.

  The first projecting portion 90 is provided so as to project to the lower end side of the first bracket portion 22 on the right side when the adhesive tape cartridge TK is mounted. The first locking portion 91 is smaller (thin) in the thickness direction than the first bracket portion 22 on the right side. The first locking portion 91 is formed on the first projecting portion 90 when the first roll R1 is switched to the unlocked state (specifically, when the first operating force is input to the first engaging member L1). On the other hand, when the first operating force is input, the first engaging member L1 is locked (hooked) along the moving direction (the direction from the right to the left), so that the first bracket on the right side by the first operating force. It suppresses that the part 22 bends to the left side (state of FIG. 11). In FIG. 11, illustration of the first roll R1 supported by the first bracket portions 22 and 22 and the first engagement member L1 fixed to the first bracket portion 22 on the right side is omitted. Yes.

  The second projecting portion 92 is provided so as to project to the lower end portion side of the second bracket portion 24 on the right side when the adhesive tape cartridge TK is mounted. The second locking portion 93 is smaller (thin) in the thickness direction than the second bracket portion 24 on the right side. The second locking portion 93 is formed on the second projecting portion 92 when the second roll R2 is switched to the unlocked state (specifically, when the second operating force is input to the second engaging member L2). On the other hand, when the second operating force is input, the second engaging member L2 is locked (hooked) along the moving direction (the direction from the right to the left) so that the second bracket on the right side by the second operating force. It suppresses that the part 24 bends to the left side.

  Here, an example of the assembly procedure of the third core member 40 having the above-described configuration will be described. That is, when assembling the third core member 40, first, the cylindrical portion 45 of the first outer cylinder 42 is extrapolated to the outer peripheral side of the left end portion of the inner cylinder 41. At this time, the paper core 44 is not yet mounted on the outer peripheral side of the cylindrical portion 45, and as shown in FIGS. 19 to 21, the inner and outer cylinder engaging / disengaging portions 49, 49, 49 of the cylindrical portion 45 are projected. The state in which the portion 49c can be sequentially engaged with and detached from each of the plurality of engaging grooves 41b on the inner cylinder 41 side, that is, the shaft center of the first outer cylinder 42 can be released from the engagement of the protrusion 49c with the engaging portion 41b. In this state, movement in the O3 direction is allowed. Thereby, the first outer cylinder 42 is movable in the direction of the axis O3. With this configuration, the user can set the separation distance w when the cylindrical portion 47 of the second outer cylinder 43 is attached to the right end portion of the inner cylinder 41 as described later as the axis of the paper core 44. It can be appropriately adjusted according to the dimension in the direction of the center O3. In FIG. 19, the protrusion 49c is engaged with the leftmost engagement groove 41b, and in FIG. 20, the protrusion 49c is disengaged from the leftmost engagement groove 41b. In a state where the first outer cylinder 42 has moved to the right side from the position shown in FIG. 19, in FIG. 21, the first outer cylinder 42 has moved to the right side from the position shown in FIG. Represents a state of being engaged with the next engagement groove 41b.

  The first outer cylinder 42 is arranged in the direction of the axis O3 such that the protrusions 49c of the inner and outer cylinder engaging / disengaging portions 49, 49, 49 are engaged with the engaging grooves 41b corresponding to the widthwise dimension of the paper core 44. Moved to. Thereafter, as shown in FIGS. 22 and 23, the paper core 44 is positioned by the flange 46 so that the left end is in contact with the right end surface 46a of the flange 46 of the first outer cylinder 42. 1 is mounted on the outer peripheral side of the cylindrical portion 45 of the outer cylinder 42. When the paper core 44 is attached to the outer peripheral side of the first cylindrical portion 45, the inner and outer cylinder engaging / disengaging portions 49, 49, 49 of the cylindrical portion 45 are arranged such that the convex portion 49 b group has a diameter larger than the inner peripheral portion of the paper core 44. When pressed inward in the direction, the flat plate portion 49a bends inward in the radial direction, and the protrusion 49c engages with the width direction dimension of the paper core 44 among the plurality of engaging grooves 41b on the inner cylinder 41 side. A state where the groove 41b is engaged and is not separated from the engagement groove 41b, that is, the first outer cylinder 42 is not allowed to move in the direction of the axis O3. As a result, the first outer cylinder 42 cannot move in the direction of the axis O3.

  24 and 25, the cylindrical portion 47 of the second outer cylinder 43 is detachably attached to the outer peripheral portion of the right end portion of the inner cylinder 41 where the paper core 44 exists on the outer peripheral side (in detail). Is inserted between the right end of the paper core 44 and the right end of the inner cylinder 41). At this time, the cylindrical portion 47 has a group of convex portions 471 at the respective circumferential positions 47a, 47a, 47a, the inner peripheral portion of the right end portion of the paper core 44 and the concave portions 41c, 41c, 41c on the inner cylinder 41 side. It is inserted between the right end portion of the paper core 44 and the right end portion of the inner cylinder 41 so as to be press-fitted into the gap. At this time, the right end portion of the paper core 44 is positioned by the flange 48 so that the right end portion contacts the left end surface 48 a of the flange 48 in the second outer cylinder 43. As described above, the third core member 40 is assembled.

<Paper core>
Here, as described above, the third core member 40 has the printed adhesive tapes 152 and 153 in which the release material layer 151 has been peeled off from the printed adhesive tape 150 ′ at the peeling portion 13 around the axis O 3. Used to wind sequentially. That is, as the third core member 40 as a whole rotates around the axis O3, the printed adhesive tapes 152 and 153 are sequentially wound around the outer periphery of the paper core 44. And in order to attain smoothness when starting such winding operation | movement, as shown in FIG.18 and FIG.26, the 3rd core member 40 is provided with the leader tape 80 (tape piece). .

  The leader tape 80 has one end 80 a extending outward from the paper core 44 and the other end 80 a extending inward from the paper core 44. The ends of the printed adhesive tapes 152 and 153 to be wound around the paper core 44 are connected to one end 80a of the leader tape 80 by, for example, adhesive. 18 and 26 illustrate a state in which the end portions of the printed adhesive tapes 152 and 153 are not connected to the one end portion 80a of the leader tape 80. As a result, the third core member 40 rotates about the axis O3 and the paper core 44 rotates about the axis O3, so that the other end 80b of the leader tape 80 extends along the circumferential direction of the paper core 44. Moving. As a result, the printed adhesive tapes 152 and 153 connected to the one end 80a on the opposite side of the leader tape 80 are pulled with the movement of the leader tape 80, and are sequentially wound around the outer periphery of the paper core 44. .

  Here, suppose a case in which the other end 80b of the leader tape 80 is simply attached to the outer peripheral surface of the paper core 44 (hereinafter referred to as “outer attaching structure” as appropriate). In this structure, when one side of the leader tape 80 is affixed to the affixed portion so as to be opposite to the rotation direction, the third core member 40 rotates around the axis O3. Thus, when the one end portion 80a of the leader tape 80 is pulled as described above, no force acts in the direction of peeling off the attachment portion, and there is no problem. However, when one side of the leader tape 80 is affixed to the affixed portion so as to be on the rotational direction side, the third core member 40 rotates around the axis O3 and the leader tape 80 is rotated. When the one side end portion 80a is pulled as described above, a force acts in such a direction as to peel off the affixed part, and the durability of the affixed part is lowered. That is, in the case of the above-described pasting structure, there is a possibility that difficulty may occur in the integrity of the leader tape 80 and the paper core 44 depending on the rotation direction of the third core member 40.

  Therefore, in the present embodiment, in order to avoid the above-described adverse effects, the other end 80b of the leader tape 80 can be switched on the third core member 40 according to the rotation direction of the third core member 40. The structure which supports is provided. Hereinafter, the details will be described with reference to FIGS. 18 and 26 to 28.

  As shown in FIGS. 18 and 26 to 28, the paper core 44 is provided with a through hole 44 a penetrating the radial inner side and the radial outer side of the paper core 44. At this time, the other end 80b of the leader tape 80 passes through the through hole 44a from the radially outer side of the paper core 44 and is inserted into the radial inner side of the paper core 44. For example, an appropriate tape or adhesive is used. The paper core 44 is fixed (connected) to the inner peripheral surface (inner peripheral portion) of the paper core 44 by fixing means (connection means, not shown). The through hole 44a and appropriate fixing means constitute a tape piece support mechanism described in each claim. At this time, without using the fixing means, the other end 80b of the leader tape 80 inserted inside the paper core 44 in the radial direction is connected to the inner peripheral portion of the paper core 44 by restraint or engagement. May be. 26 and 27, the other end 80b of the leader tape 80 is not fixed to the inner peripheral surface of the paper core 44.

  In the present embodiment, the center position P1 of the leader tape 80 in the tape width direction (that is, the direction of the axis O3), the center position P2 of the through hole 44a of the paper core 44 in the axis O3 direction, and the axis of the paper core 44 The center position P3 in the direction of the center O3 substantially coincides with each other. In other words, the leader tape 80, the through hole 44a, and the paper core 44 have a line-symmetric structure in the direction of the axis O3.

  Then, the other end 80b of the leader tape 80 is fixed to the inner peripheral surface of the paper core 44 as described above, so that the other end 80b has the opposite one end 80a of the paper core 44. The first position (the state shown in FIG. 28A) that takes a form along the one side in the circumferential direction (specifically, the clockwise side) of the outer peripheral portion of the paper and the one end 80a on the opposite side are the paper core 44. The second position (the state shown in FIG. 28 (b)) is a mode that can be switched along the other circumferential side of the outer peripheral portion (specifically, the counterclockwise side).

  That is, when the third core member 40 rotates to one side (specifically, the clockwise side), as shown in FIG. 28A, the other end 80b of the leader tape 80 is in the first position. Thus, the one end portion 80 a of the leader tape 80 is in a form along the one circumferential side of the outer peripheral portion of the paper core 44. Further, when the third core member 40 rotates to the other side (specifically, the counterclockwise direction), as shown in FIG. 28 (b), the other end 80b of the leader tape 80 is moved to the second side. The position is such that one end 80 a of the leader tape 80 is along the other circumferential side of the outer periphery of the paper core 44.
