Description

  The present invention relates to a device for pulling out a narrow strip-like sheet wound in a roll shape, for example, an adhesive tape. Specifically, the cutting portion of a wide-width sheet cut in the width direction is attached to the next sheet with an adhesive tape or the like. The present invention relates to a tape drawing device for correctly pulling out and bonding an adhesive tape to a sheet adding portion to be added when bonding and adding.

  In order to connect a non-defective part by feeding out a wider sheet than before, only the non-defective part is connected, the sheets before and after the defective part are cut in the width direction, the defective part is taken up and removed as a defective part, and only the non-defective part is joined. It has been practiced to add and paste on the base (see, for example, Patent Documents 1 and 2), but the joining at the time of addition is not specifically shown, and is almost done manually. It was.

  In general, when a wide sheet is cut at a right angle in the feed direction and the cut surface is bonded to the next sheet with an adhesive tape or the like, the adhesive tape to be bonded is bonded to the correct position parallel to the sheet cut surface. Although it is necessary, when the tape tip is grasped from the roll-shaped wound adhesive tape roll and drawn on the upper flat development bar 11 having the suction holes 12 as shown in FIG. 3, it is pulled out as shown in FIG. 4 (b). The tape sways from side to side in the process, and the sticking to the sheet in the next process may become wrinkled or not straight.

  However, in recent years, plastic sheets for liquid crystal televisions, lithium batteries, etc. are expensive and high quality is required with little loss, so accurate tape withdrawal is strongly desired. No tape withdrawal means corresponding to the above has been found.

  The present invention copes with the actual situation as described above, and in particular, by finding an appropriate pulling means for the tape to be pulled out, the tape can be pulled out in a straight line without meandering without wobbling left and right tapes in the middle of being pulled out and deployed. The purpose is to prevent wrinkles from appearing on the sticking and to achieve accurate linear joining of the sheets.

  In other words, the present invention suitable for the above-mentioned purpose is a device for drawing and unfolding a narrow strip tape wound in a roll shape, and holding the tape pulling bar having a tape knob at the lower end and reciprocatingly driving in the drawing direction. An endless belt, and a sticking base disposed on the lower side of the endless belt, receiving the tape drawn by driving the endless belt, and having a developing bar on the top surface. The tape drawing device is formed in a medium-high curve shape in a cross-section orthogonal to the direction, and can draw the tape to be developed in a straight line without meandering to the center of the development bar. In addition, it is suitable that the sticking stand in the above is an adsorption stand, and the expansion | deployment bar has a tape adsorption hole.

  According to the device of the present invention, when the sheet cut surface cut at right angles to the sheet drawing direction is bonded to the next sheet and added, the drawn-out adhesive tape does not meander through the middle and high curve portions on the upper surface of the developing bar of the sticking table. The tape is held in a straight line, swings to the left and right while being pulled out, does not wrinkle on the sheet, and does not stick to the sheet in a straight line.

It is a schematic diagram showing a tape drawer device according to the present invention. It is a longitudinal cross-sectional view which shows the shape of the expansion | deployment bar which concerns on this invention. It is a longitudinal cross-sectional view which shows the shape of a general expansion | deployment bar. It is a sheet drawing state top view in the development bar of the upper surface of an adsorption stand, (a) is the case of the middle-high curve shape concerning the present invention, and (b) is the case of the general upper surface flat type.

  Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 is a schematic view showing a tape drawing device according to the present invention. In the figure, reference numeral 1 denotes an endless belt, and more specifically, a tape T is drawn from a narrow-band tape wound in a roll shape, for example, a roll 2 of adhesive tape. This is an endless belt for driving the tape drawer to be pulled out through the guide roll 3, and is driven to reciprocate left and right by the tape drawer motor M, and is pulled out by holding and holding a tape drawer bar 5 having a tape knob 4 attached to the lower end. The end of the tape is pinched by the tape knob 4 so that the tape T can be pulled out within a required range by driving the endless belt 1.

  Here, the tape knob 4 may be moved together with the tape pull-out rod 5 for a required length so that, for example, the adhesive tape can be attached to the joining portion in order to join the sheets, and within a predetermined range of the endless belt. The movement is performed by the reciprocating drive, and the tape is applied. Of course, the tape drawing is not limited to the case of seaming, and the tape drawing is the same for general bonding. On the other hand, 6 is a developing bar which receives the tape drawn out as described above, and develops the tape over the required length along with the movement of the tape knob 4, and preferably has the required length accompanying the above-mentioned tape application. The tape drawn out in this manner is arranged on the upper surface of the affixing base 8 so that the tape can be securely held thereon. The unfolding bar 6 that receives the tape may be rotated 180 ° together with the affixing base depending on the tape bonding mode thereafter, and can be rotated by 90 °. You may enable it to rotate so that pasting may be easy. Of course, it goes without saying that it does not have to rotate.

  The sticking table 8 having the developing bar 6 disposed on the upper surface is preferably a suction table connected to a vacuum mechanism. In accordance with this, a tape sucking hole 7 is provided on the upper surface of the developing bar 6 to secure the tape. It is preferable to hold it.

  The drawing device of the present invention includes an endless belt 1 having a tape reel 5 that holds the tape knob 4 as described above, and a sticking base 8 that has a developing bar 6 on the upper surface for receiving and developing the drawn tape. The tape T unwound from the winding roll 2 is pinched by the tape knob 4 and driven by the endless belt 1 so as to have a required range on the developing bar 6 on the lower sticking table together with the tape pulling bar 5 It is developed over the length of, preferably adsorbed and held. When the tape to be pulled out is an adhesive tape, the adhesive side is usually drawn out with the adhesive side as the upper surface, and, for example, the sheet-to-sheet joining portion is rotated from the lower surface or 180 ° and stuck from the upper surface.

  Thus, the drawer device of the present invention is developed on the developing bar 6 by forming the upper surface of the developing bar 6 in a cross section perpendicular to the tape pulling direction, that is, in the width direction as shown in FIG. The formed tape is formed so as to be developed in a straight line without meandering.

  FIG. 3 shows a case of a normal flat upper surface shape as compared with FIG. 2 having a medium-high curve shape. When the developed state of the tape is compared with both, the case of the medium-high curve shape upper surface as shown in FIG. As shown in FIG. 4A, the tape T is unfolded in a straight line on the unfolding bar 6, whereas when the upper surface is flat as shown in FIG. 6 The meandering development of the middle and high-curved bar of the present invention does not sway left and right while being drawn out, and it does not interfere with the pasting of the sheet in the next process and has good results. It was.

  As described above, it can be seen that the tape drawing device of the present invention can accurately draw the tape by making the upper surface of the developing bar have a medium-high curve shape as described above, and is extremely effective for adding an expensive plastic sheet.
