Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to, for example, a band material bonding apparatus and a band material removing apparatus for bonding a band material that binds a predetermined number of stacked sheets.
[0002]
[Prior art]
The adhesive device for the band material is a water paste or heat sealant applied to the band material by pressing the heating block against the overlapping part of the band material wound around the laminated paper sheets and overlapping the both ends, and heating it. Etc. are melted and bonded.
[0003]
By the way, at the time of bonding of the band material, a part of water glue or heat sealant applied to the band material wraps around between the laminated paper sheet and the band material to bond the laminated paper sheet and the band material. It may adhere. In such a state, if the strip material is forcibly removed from the laminated paper sheet sent to the next process, the strip material may not be removed or the laminated paper sheet itself may be soiled. .
[0004]
Therefore, in order to prevent this, after inserting a peeling spatula material (insertion piece) between the both-end adhesive part of the strip and the medium, after peeling the both-end adhesive part of the strip from the laminated paper sheets, The strip is removed.
[0005]
[Problems to be solved by the invention]
However, conventionally, in the band bonding apparatus, since the heating block for heating the band material is exposed to the outside, there is a risk that the operator may accidentally touch the heating block and get burned. It was.
Further, when there is not sufficient flatness at the overlapping portions at both ends of the strip, poor adhesion may occur.
[0006]
On the other hand, in the strip material removing device, the spatula material is simply formed in a flat plate shape. For example, when the strip material is wound with one end portion sandwiched between laminated paper sheets, When the spatula material was inserted, the spatula material could collide with the belt material and damage the paper sheets.
[0007]
The present invention has been made by paying attention to the above circumstances, and can bond a band material without bringing an operator into contact with the heating unit, and also makes an insertion piece for peeling collide between the band material and the medium. An object of the present invention is to provide a band material bonding apparatus and a band material removing apparatus that can be inserted without any problem.
[0009]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, the invention according to claim 1 is a removing means for removing from the medium a band member wound around a medium and overlapped at both ends and bonded to each other by an adhesive. Prior to the removal of the strip by the removing means, there is provided a stripping means for inserting a comb-like insertion piece between the strip and the medium to peel the both-end adhesive portions of the strip from the medium. The insertion piece has a plurality of thin pieces arranged to face each other at a predetermined interval, and a blade portion is formed at an end of the thin piece on the insertion side .
[0010]
DETAILED DESCRIPTION OF THE INVENTION
The present invention will be described below with reference to embodiments shown in the drawings.
FIG. 1 is a perspective view showing a belt bonding apparatus. This bonding apparatus heats and bonds the overlapping portions Ka of the belt member K wound around a predetermined number of stacked paper sheets and overlapped at both ends. An adhesive is applied to the band material K, and the adhesive is melted and bonded by heating.
[0011]
In the figure, reference numeral 1 denotes a base to which a drive motor 2 is attached. A bracket 4 is attached to the base 1 via a stud 3, and an insulator 5 is attached to the bracket 4. Below the insulator 5, a heating unit 6 described later and a box-shaped cover material 7 that covers the heating unit 6 are disposed.
[0012]
FIG. 2 is an exploded perspective view showing the bonding apparatus.
The heating unit 6 includes a housing 8, and a heating block 10 and a heat transfer block 11 are disposed in the housing 8. The housing 8 is connected to the holding member 13 by a plurality of springs 12... A heat source block 15 is provided above the heating unit 6, and the heat source block 15 is attached to the insulator 5. The heat source block 15 is heated by a heater (not shown).
[0013]
A movable bracket 17 is attached to the base 1 via a slide rail 16. Further, a link arm 18 is coupled to the shaft of the drive motor 2, and a movable bracket 17 is connected to the link arm 18 via a connection pin 19.
The movable bracket 17 is linearly moved up and down by the rotation of the link arm 18. The holding member 13 of the heating unit 6 is attached to the movable bracket 17, and the heating block 10 is moved from the home position where the heat transfer block 11 comes into contact with the heat source block 15 and is heated by the linear movement of the movable bracket 17. Move to the position where it touches and heat seals.
[0014]
Further, a box-shaped cover material 7 is attached to the movable bracket 17 via a slide rail 21. Normally, the cover material 7 hangs down due to its gravity, but is held in place by a stopper 22 attached to the movable bracket 17.
[0015]
The cover material 7 covers the peripheral part of the heating part 6 that moves together with the movable bracket 17 and the lower surface part of the heating block 10 except for the path. That is, the heating block 10 is recessed above the lower surface portion of the cover member 7 so that the hand of the worker is not touched.
[0016]
Next, the bonding operation of the bonding apparatus will be described with reference to FIGS.
As shown in FIG. 3, when the drive motor 2 rotates in the forward direction from the state in which the heating block 10 and the cover material 7 are retracted upward, the link arm 18 is rotated downward and is movable as shown in FIG. The bracket 17 moves downward and the heating block 10 and the cover material 7 are lowered.
[0017]
Further, when the link arm 18 is rotated downward and the movable bracket 17 is moved downward, as shown in FIG. 5, the heating block 10 and the cover material 7 are further lowered, as shown in FIG. After the lower surface portion of the cover material 7 is first pressed against the peripheral portion of the both-end overlapped portion Ka of the band material K, the heating block 10 is lowered to the both-end overlapped portion Ka of the band material K as shown in FIG. Pressed. By pressing the heating block 10, the both-end overlapping portion Ka is heated and the adhesive is melted and bonded.
[0018]
After this bonding is completed, the drive motor 2 is rotated in the reverse direction, the link arm 18 is rotated upward, and the movable bracket 17 is raised. Thereby, the heating block 10 and the cover 7 material are raised and returned to the home position. Thereafter, the same operation is sequentially repeated to continue the bonding.
[0019]
As described above, according to this embodiment, since the peripheral portion of the heating block 10 is covered by the cover material 7, the exposure amount of the heating block 10 can be minimized, and an operator mistakenly heats the heating block. 10 can be prevented from touching.
[0020]
In addition, prior to the heating block 10 coming into contact with the both ends overlapped portion Ka of the strip K, the lower end surface portion of the cover material 7 is brought into contact with the peripheral portion of the both ends overlapped portion Ka of the strip K. Then, the heating block 10 can be brought into contact with the both-end overlapped portion Ka of the strip K, and stable and good adhesion is possible.
[0021]
On the other hand, FIG. 7 shows a state in which the band material K is normally wound around the laminated paper sheets and bound, and FIG. 8 shows that the end of the winding start of the band material K is inserted into the laminated paper sheet P (this is shown in FIG. This is a state in which it is wound and bound in a state called a center insert).
[0022]
FIG. 9 shows the cutting position Kc of the band material K performed in the subsequent process of the apparatus, and FIG. 10 shows the band material K that has been cut and removed from the laminated paper sheet P.
The cut strip K is forcibly extracted and removed by the removing device 23. At this time, if the both-end adhesive portions Kb of the strip K are bonded to the laminated paper sheet P, the strip K may not be removed or the laminated paper sheet P may be damaged.
[0023]
Therefore, when removing the band material K, as shown in FIG. 11, a spatula material 24 as an insertion piece is inserted between the laminated paper sheet P and the both-end adhesive portion Kb of the band material K, and both ends are inserted. After the bonding portion Kb is peeled off from the laminated paper sheet P, the band material K is removed.
[0024]
However, since the conventional spatula material 24 is simply formed in a flat plate shape, for example, as shown in FIG. 12, if the stop position of the transported sheet bundle T is too short of the normal position, the spatula material If the belt 24 collides with the upper end surface of the band member K, or as shown in FIG. 13, if the band member K is a medium insert, even if the sheet bundle T stops at the normal position, The apparatus may stop due to the collision with the upper end surface of the band material K to cut the band material K or the collision with the band material K.
[0025]
Therefore, in the embodiment of the present invention, the spatula material 26 is formed in a comb-teeth shape as shown in FIG. By configuring the spatula 26 in a comb-like shape in this way, even when the stop position of the sheet bundle T is too short of the normal position, or even when the band material K is in the middle position. When the band material K is inserted into the portion of the spatula material 26 where the comb teeth are cut, the collision with the band material K can be avoided.
[0026]
Accordingly, the spatula material 26 can be inserted and the both-end adhesive portion Kb can be peeled off from the laminated paper sheet P without cutting the band material K or stopping the operation of the apparatus. The spatula material 26 is inserted between the belt material K while pushing the laminated paper sheet P.
[0027]
FIG. 15 shows another embodiment of the spatula material.
The spatula 31 in this embodiment has a plurality of thin plates 31a arranged opposite to each other at a predetermined interval, and these thin plates 31a are integrated via a connecting plate 31b. And the sharp blade part 31c is formed in the lower end part of the thin plate 31a ....
[0028]
According to this embodiment, the spatula material 31 can be smoothly inserted into the laminated paper sheet P with a small insertion resistance, and the both-end bonded portions Kb of the belt material K2 can be easily peeled off.
As described above, according to the embodiment of the present invention, the heating block 10 that is movable to heat-seal the strip material K1 is covered with the cover material 7, so that the worker can perform the operation during the bonding operation and the maintenance work. It is possible to prevent erroneous contact with the heating block 10 and improve safety.
[0029]
In addition, the cover material 7 is movable relative to the heating block 10, and when the heating block 10 is on standby, the heating block 10 can be placed on the upper side of the lower surface of the cover material 7 to stand by, An operator's contact with the heating block 10 can be prevented more reliably.
[0030]
Further, when the band material K is bonded, the cover material 7 precedes the peripheral portion of the both ends overlapped portion Ka of the band material K before the heating block 10 contacts the both ends overlapped portion Ka of the band material K to be bonded. Therefore, the flatness around the both ends overlapped portion Ka to which the band material K is to be bonded is obtained, and a stable adhesive force can be obtained.
[0031]
On the other hand, since the spatula materials 24 and 26 for peeling the adhesive portion Kb of the band material K from the laminated paper sheet P are configured in a comb-teeth shape, the band material K is wound and inserted into the laminated paper sheet P. Regardless of the position, it can be reliably inserted without contacting the belt material K.
[0032]
【The invention's effect】
As described above, the present invention covers the outer peripheral part of the heating part for heating and bonding the both ends overlapping part of the band material with the cover, so that the worker does not accidentally contact the heating part, Risk of burns and the like can be prevented.
In addition, since the stripping material to be inserted between the strip and the medium is formed in a comb-like shape, even if the medium is displaced from a predetermined position, or one end of the strip is inserted into the medium. Even if it is a thing, there exists an advantage which can insert and peel reliably, without making an insertion material collide with a strip | belt material.
