  Next, the cutter blade 56 of the tape cutting device 14 provided on the upstream side of the binding position P1 shown in FIG. 8 is lowered from the solid line position to the two-dot chain line position, and the adhesive tape T is cut to a predetermined length. .

  Next, the suction heads 70 and 70 holding the adhesive tape T cut to a predetermined length are further lowered. Then, as shown in FIG. 12, the pressing plate 67 attached to the lower ends of the guide rods 65, 65 and biased downward by the spring 68 moves the longitudinal central portion of the adhesive tape T to the bucket 24 of the transport device 11. The two stacked articles X and X are pressed against the upper surface of the upper article X. In that case, both upstream and downstream ends of the adhesive tape T sucked and held by the suction heads 70 and 70 are formed by a roller 24a ′ provided in the bucket 24 and a roller 24a ′ provided in the preceding bucket 24 adjacent thereto. Each is supported from below. Therefore, the upstream and downstream ends of the adhesive tape T are not crumpled or tangled. Further, the preceding bucket 24 holds a bundled product X ′ obtained by binding the articles X and X with the adhesive tape T. In FIG. 12 and FIGS. 13 and 15 to 17 described later, the bucket 24 and the articles X and X of the transport device 11 are indicated by a two-dot chain line in order to avoid complication of the drawing and to clearly indicate the adhesive tape T. Show.

  As shown in FIG. 13, the suction heads 70, 70 release the suction holding of the upstream and downstream ends of the adhesive tape T when lowered to a predetermined position. During the lowering, the adhesive tape T is wound over the upstream side and the downstream side in the transport direction d of the articles X and X held in the bucket 24 of the transport device 11, and the article is supported by the brazing members 71 and 71. Paste X and X while scrubbing them on the upstream and downstream sides. In that case, the pressing plate 67 presses the articles X and X moderately with the adhesive tape T sandwiched against the downward biasing force of the spring 68.

  The upstream end of the adhesive tape T is positioned between the rollers 86... 86 of the upstream flange unit 81 of the tape applying device 16 and the rollers 93... 93 of the upstream clamping unit 88. The downstream end is located between the rollers 98... 98 of the downstream hooking unit 95 and the rollers 102... 102 of the downstream clamping unit 99.

  Here, the clamping operation of the upstream end portion of the adhesive tape T by the rollers 86 of the upstream hooking unit 81 and the rollers 93 of the upstream clamping unit 88 will be described.

  When the suction holding of the upstream end portion of the adhesive tape T is released, as shown in FIG. 14 (a), the attachment post 84 is set to enter the brazing operation by the brazing member 85 of the upstream brazing unit 81. When the movement in the conveyance direction d starts, the lever member 90 of the upstream clamping unit 88 is supported by the sliding contact between the cam surface of the cam 89 and the cam follower 91 and the urging to the upstream side by the spring 94. It begins to swing in the direction of the mounting post 84 about the shaft 90a. At the time of the illustrated example, the rollers 86... 86 of the upstream hooking unit 81 and the rollers 93... 93 of the upstream clamping unit 88 do not clamp the upstream end of the adhesive tape T, and the stopper 92 is attached. It is not in contact with the post 84.

  As shown in FIG. 14 (b), when the mounting post 84 of the upstream flange unit 81 further moves in the article transport direction d, the cam surface of the cam 89 and the cam follower 91 are slidably contacted to the upstream side by the spring 94. With the urging, the lever member 90 of the upstream clamping unit 88 further swings in the direction of the mounting post 84 about the support shaft 90a. Finally, the rollers 86... 86 of the upstream hooking unit 81 and the rollers 93... 93 of the upstream clamping unit 88 come into contact with each other to clamp the upstream end of the adhesive tape T, and the stopper 92 is attached to the mounting post 84. Interact. In this state, the attachment post 84 moves to a predetermined position on the downstream side, so that the brazing member 85 is attached with the upstream end portion of the adhesive tape T being attached to the bottom surface of the article X with a scissors.

  That is, when the support member 83 of the upstream flange unit 81 moves in the direction of the arrow d along the guide rail 82 from the state shown in FIG. 15 by driving the motor 107, the article held in the bucket 24 of the transport device 11 The brazing member 85 located at a high position along the bottom surface of X is an upstream end of the adhesive tape T sandwiched between the rollers 86... 86 of the upstream brazing unit 81 and the rollers 93. A part is affixed so that it may be attached to the bottom face of the said article | item X. On the downstream side, the lever member 101 of the downstream clamping unit 99 swings in the direction of the rollers 98... 98 of the downstream flange unit 95 around the support shaft 101a by the operation of the air cylinder 103, and the rollers 98 on both sides. ... 98, 102 ... 102, the downstream end of the adhesive tape T is clamped.

  As shown in FIG. 16, when the adhesive tape T is attached to the bottom surface of the article X by the flange member 85 of the upstream flange unit 81, the electric cylinder 87 is activated and the guide rail 82 and thus the flange member 85. The rollers 86... 86, 93... 93 are positioned at a lower position below the bottom surface of the article X, and in this state, these members 85, 86. When moving upstream, the upstream clamping unit 88 performs an operation opposite to the operation shown in FIG. 14 and waits for the upstream end of the adhesive tape T to be clamped for the next binding.

  Next, a description will be given of a pasting operation of the downstream end portion of the adhesive tape T by the tacking roller 97 of the downstream tacking unit 95. As shown in FIG. In the state where the downstream end of the adhesive tape T is clamped by the rollers 102... 102 of the side clamping unit 99, as shown in FIG. When moved in the direction d, the downstream end of the adhesive tape T is attached to the bottom surface of the article X while being attached to the bottom surface of the article X by the anchoring roller 97 fixed to the downstream anchoring unit 95. End the binding for X.

  By configuring as described above, first, the tacking member 85 of the upstream tacking unit 81 that constitutes one of the tape applicators 16 is moved, and the tacking roller 97 of the downstream tacking unit 95 that constitutes the other. Therefore, only one drive means, that is, the motor 107 for movement is required, and the tape bundling device 3 with a simplified configuration is realized.

  Further, the upstream brazing member 85 is advanced to the binding position P1 instead of moving up and down so that the upstream and downstream brazing means are switched at the binding position P1 as in the prior art. When the side end portion is affixed to the bottom surface of the article X, the conveying device 11 conveys the articles X and X to the downstream side, so that the downstream end of the adhesive tape T is fixed by the fixed flange roller 97 on the downstream side. Since the portion is affixed to the bottom surface of the article X, it does not take much time to affix both end portions of the adhesive tape T to the bottom surface of the article X, and the speed can be increased.

  Further, a pair of upstream and downstream suction heads 70, 70 for holding the adhesive tape T cut to a predetermined length are provided, and the suction heads 70, 70 are arranged before the completion of the lowering, that is, the bottom surface of the article X by the tape applying device 16. Prior to the attachment of both ends of the adhesive tape T to the tape, the holding of the both ends is released, so that excessive tension is applied to the adhesive tape T when the both ends are attached to the bottom surface of the article X. There is no. Therefore, when using the adhesive tape T that is weak in strength, problems such as breakage do not occur.

  Furthermore, the both ends of the adhesive tape T that has been suspended after being released from the holding by the suction heads 70 and 70 are clamped using the rollers 93... 93, 102... 102 of the upstream and downstream clamping units 88 and 99, respectively. The vicinity of the end is not tangled, and a stable sticking of the adhesive tape T is ensured. It should be noted that when the both end portions of the adhesive tape T described above are attached, the end portions are sandwiched by the rollers 93... 93, 102.

  The operation of the rollers 93... 93 of the upstream clamping unit 88 when contacting the rollers 86... 86 of the upstream hooking unit 81 is performed downstream of the hooking member 85 of the upstream hooking unit 81 and the rollers 86. Since it is interlocked with the movement to the side, the clamping of the upstream end portion of the adhesive tape T and the attachment of the end portion to the bottom surface of the article X can be performed reliably and efficiently.

  Further, the brazing member 85 of the upstream brazing unit 81 is located at a high position along the bottom surface of the article X when moving from the upstream side to the downstream side via the electric cylinder 87, so that the upstream end of the adhesive tape T Since the part passes through a position below the bottom surface of the article X when returning from the downstream side to the upstream side with the part securely attached to the bottom surface of the article X, the adhesive tape T of the adhesive tape T attached to the bottom surface of the article X The upstream end portion is not touched unnecessarily, and the concern that the upstream end portion of the adhesive tape T attached is peeled off is eliminated.

  And since the brazing member 85 of the upstream side bridging unit 81 applies the upstream end of the adhesive tape T to the bottom surface of the article X via the brush member, the adhesive tape T is firmly attached along the shape of the article X. While being affixed, damage to the adhesive tape T, packaging material, contents, etc. during affixing is reduced.

  It should be noted that the present invention is not limited to the above-described embodiment that has been specifically described in detail, and may be any that are within the spirit of the present invention. For example, in the downstream side tacking unit 95, a brazing member made of a brush member may be used instead of the tacking roller 97. Thereby, while the downstream edge part of the adhesive tape T is firmly affixed along the shape of the article | item X, damage to the adhesive tape T at the time of affixing, a packaging material, a content, etc. is reduced.

  As described above, according to the present invention, there is provided a tape bundling device that can be simplified in configuration and speeded up. That is, the present invention relates to a tape binding device that binds a plurality of articles stacked one above the other with a tape, and is widely suitable for the technical field of article packaging.
