DETAILED DESCRIPTION OF THE INVENTION [Industrial applications]

The present invention relates to a tape supply apparatus for automatically peeling off a leading end of a tape from a tape reel on which the tape is wound and having an outer leading end attached thereto, and continuously supplying the tape.

[Prior art]

In packing work, veneer veneer reinforcement or joining work, etc., take out the tape from a tape reel on which a large amount of tape has been wound in advance and affix it to the outer peripheral surface of the packing container or to the adherend such as veneer veneer. ing. When the tape wound around the tape lead runs out in these operations, the operator replaces and installs a new tape reel by hand each time, and then attaches the leading end attached to the outermost periphery of the tape reel to the tape. It is peeled off from the reel and led out continuously.

[Problems to be solved by the invention]

However, in the above-described conventional method, every time the tape reel is replaced, the operator manually peels off the taped end from the outermost peripheral surface of the tape reel and passes the tape through a predetermined path. I had to go out. For this reason, it took a long time to replace the tape reel, and the work efficiency was low. Further, when exchanging the tape reel, the transport of the adhered object must be temporarily interrupted, and the work of processing the adhered object cannot be performed smoothly.
In particular, when transporting continuously and at a high speed, such as veneer veneer cut by veneer lace, the cutting of raw wood by veneer lace must be interrupted each time the tape reel is replaced. In addition, it takes time for the transport speed of the veneer veneer to recover to the predetermined speed, and the log cutting efficiency is significantly deteriorated, and the plywood manufacturing efficiency is reduced. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional drawbacks, and its purpose is to automatically peel off the leading end from a tape reel on which a tape is wound and supply the tape continuously. It is an object of the present invention to provide a tape supply device capable of reducing the labor and efficiency of a tape reel exchanging operation and facilitating the processing of an adhered object.

[Means for solving the problems]

For this reason, the present invention, a tape is wound, the tip of the outer periphery is inserted into the center of the tape reel attached to the tape located inside, a supporting member that rotatably supports the tape reel, A resistor that moves relative to the support member, and that can freely contact and separate from the outer peripheral surface of the tape reel;
A rotation that moves relative to the support member and abuts against the outer peripheral surface of the tape reel at a position on the upper side in the tape feeding direction from the position where the resistor comes into contact with the outer peripheral surface of the tape reel; A roll, and a driving member for rotating at least one of the rotating roll and the support member to rotate the tape reel in a tape feeding direction, so that the tape can be taken out from the tape reel. .

Effect of the Invention

Since the present invention is configured as described above, when the resistor is pressed against the outer peripheral surface of the tape reel that rotates in the tape feeding direction with the driving of the driving member, the tape located at the outermost peripheral side is slackened. Occurs. When the slack has a predetermined length, the slack portion is introduced between the rotating roll and the resistor, which rotate in contact with the outer peripheral surface of the tape reel, and is drawn out. At this time, the tape is peeled off from the outer peripheral surface of the tape with its leading end positioned inside, and is continuously fed out.

An embodiment of the tape supply device according to the present invention will be described below with reference to the drawings. 1 is a perspective view schematically showing a tape supply device, and FIG. 2 is an exploded perspective view of a portion II in FIG. 1. A movable frame 5 is slidable in a longitudinal direction on a frame 3 of the tape supply device 1. The movable frame 5 is connected to a rod of a first cylinder 7 attached to the frame 3. When the rod of the first cylinder 7 is retracted, the movable frame 5 is urged to move in the direction indicated by the solid arrow A shown in FIG. Further, a chuck member 9 as a support member is attached to the movable frame 5, and the chuck member 9 has a locking step at a tip end thereof and is connected to a rotatable chuck claw (both figures are shown). (Not shown), a large amount of tape 11 is wound, and when attaching a new tape reel 13 to which an outer peripheral end portion 11b is attached, the chuck member 9 is moved along with the operation of the cylinder. The tape reel is expanded while being inserted into a take-up tube (not shown) at the center of the tape reel.
I am trying to attach 13 The tape 11 wound around the tape reel 13 may be an adhesive that produces an adhesive force when wet, or may be an adhesive to which an adhesive having an adhesive force is applied in a normal state. Tip 11b located
Is attached to the outer peripheral surface of the tape 11 located inside. Reference numeral 10 shown by a broken line in FIG. 1 denotes a reel guide located on the side surface of the tape reel 13 around which the tape 11 is wound, and the winding of the tape 11 on the tape reel 13 by pressing by a pressing roll 21 described later. The state is prevented from collapsing. On the right side of the frame 3 shown in FIG.
An electric motor 17 as a driving member is mounted on the mounting frame 15, and a rotating shaft 17 a of the electric motor 17 is mounted on the chuck member 9.
It is attached so that it becomes the height according to. The rotation axis
A mounting plate 19 is rotatably supported at its intermediate portion via a bearing 20 at 17a, and a metal pressing roll 21 constituting a resistor is mounted at its shaft end. The pressing roll 21 is driven by the electric motor 17,
The tape reel 13 is rotated clockwise as a resistance to the rotation. The mounting plate 19 has a rotating roll 23.
Is rotatably supported so as to be in contact with the outer peripheral surface of the pressing roll 21 so as to rotate, and is rotated counterclockwise with the rotation of the pressing roll 21. The rotating roll 23 is formed of a rubber roll or the like having a high friction coefficient in order to efficiently rotate the tape reel 13 by contacting the outer peripheral surface of the tape reel 13. The mounting plate 19 has a mounting frame
When the rod of the second cylinder 25 attached to 15 is connected and the rod of the second cylinder 25 is retracted, only the rotating roll 23 is taped with the rotation of the mounting plate 19 in the counterclockwise direction. When the rod of the second cylinder 25 is moved forward, the first roll 21 and the rotating roll 23 are pressed against the outer peripheral surface of the tape reel 13 so that both the pressing roll 21 and the rotating roll 23 are pressed against the outer peripheral surface of the tape reel 13. The pressure in the cylinder 7 and the second cylinder 25 is adjusted. Next, the operation of the tape supply device 1 configured as described above will be described with reference to FIGS. FIG. 3 is a front view showing a rotating state of the tape reel, and FIG.
The drawings are front views showing the pressed state of the pressing roll and the rotating roll, and FIGS. 5 to 7 are front views showing the taking-out action of the tape tip. When the second cylinder 25 is retracted, a large amount of tape 11 is wound around the chuck member 9 and the first cylinder is mounted with the tape reel 13 to which the tip 11b is attached. When the rod 7 moves backward, the movable frame 5 moves in the direction indicated by the solid arrow A shown in FIG. 1, and the outer peripheral surface of the tape reel 13 is pressed against the rotating roll 23 as shown in FIG. At this time, the pressing roll 21 rotates clockwise with the driving of the electric motor 17.
The tape reel 13 is rotated clockwise by the pressure contact. When the tape reel 13 reaches a peripheral speed matching the rotation of the rotating roll 23, the rod of the second cylinder 25 is moved forward. As a result, the mounting frame 15 rotates clockwise, and the pressing roll 21 is pressed against the outer peripheral surface of the tape reel 13 together with the rotating roll 23 as shown in FIG. Since the pressing roll 21 is rotating in the opposite direction to the rotation of the tape reel 13, it becomes a resistance and the outermost tape 11
Is subjected to a braking force. Then, the outermost tape 11 is peeled off from the inner tape by this braking force, but the tape 11 is connected even if it is peeled at a portion other than the leading end 11b of the tape 11, so that the displacement is prevented, so that the tape reel Although the tape 11 does not separate outward, when the tape 11 is peeled off from the inner tape at the outer tip 11b, the tape 11 is easily displaced on the upper side in the rotation direction from the tip 11b, and the tape 11 has a slack portion 11a. (See FIG. 4.) Then, when the tape reel 13 continues to rotate, the slack portion 11a of the tape 11 located on the outermost peripheral side becomes longer due to the squeezing action of the pressing roll 21, and the slack portion 11a The tape reel 13 is pushed up in the direction opposite to the rotation direction of the tape reel 13 and is bent.
Are introduced and clamped between the pressing roll 21 and the rotating roll 23 by the rotating roll 23 which rotates in the same direction as shown in FIG. Then, when the slack portion 11a is pulled out with the rotation of the pressing roll 21 and the rotating roll 23, the tape 11 wound on the tape reel 13 has a leading end 11b.
Is peeled off from the tape reel 13 and is then fed out continuously to the discharge side of the pressing roll 21 and the rotating roll 23 (see FIG. 6). When the removal of the leading end 11b of the tape 11 is completed by the above operation, the rod of the second cylinder 25 is retracted,
By rotating the mounting plate 19 in the counterclockwise direction, the pressing of the pressing roll 21 against the outer peripheral surface of the tape reel 13 is released, and the tape is rotated by rotating the tape reel 13 at a speed corresponding to the rotation speed of the rotating roll 23. 11 is supplied while running at a predetermined speed (see FIG. 7). The unwound tape 11 is provided with an elastic member on the outer periphery of a raw wood surface or a veneer surface to be adhered by a cylindrical guide (not shown) provided on the exit side of the pressing roll 21 and the rotating roll 23. Coated idler roll (not shown)
Is pressed and bonded. In addition, when the tape 11 wound around the tape reel 13 is consumed with the supply of the tape 11, the first cylinder 7
The movable frame 5 is returned to the initial position as the rod moves forward, and a large amount of tape 11 is wound around the chuck member 9 from which the winding tube has been removed, and the distal end portion 11 located on the outermost periphery side
b replaces a new tape reel 13 attached to the tape 11 inside it, and then automatically peels off the leading end 11b of the tape 11 from the tape reel 13 by the above-described operation to continuously supply the tape. As described above, according to the present embodiment, the leading end 11b of the tape 11 can be automatically peeled off from the mounted tape reel 13 and supplied, and the replacement work of the tape reel 13 can be performed in a short time and efficiently. It can be carried out. In addition, the plurality of tape supply devices 1 configured as described above are arranged vertically or in parallel, and when the tape 11 of the tape reel 13 mounted on one of the tape supply devices 1 is consumed, the adjacent arrangement is performed. While the supply of the tape 11 from the other tape supply device 1 is attempted, one tape supply device 1
A new tape reel 13 is mounted. At the rear end of the tape 11 supplied from the other tape supply device 1, a tape 11 derived from the replaced tape reel 13 is attached.
The tape 11 can be supplied continuously without interrupting the conveyance of the adhered object by sticking the front end of the tape 11 to the continuous state. Further, in the wet adhesive tape 11 that can be adhered by adhering moisture, only the outer end portion 11b of the tape 11 is adhered to the inner tape. After being taken out and taken out, a wet application roll (not shown) is arranged on the lead-out side of the pressing roll 21 and the rotating roll 23, and the coating roll is attached to the adhesive surface of the drawn-out tape 11. Thereby, an adhesive force may be generated. As described above, in the wet adhesive tape, only the outer end portion 11b of the tape is adhered to the inner tape, and after the end portion 11b is taken out, the state wound by some external force is broken. There is a risk. In this case, water is sprayed on the side end surface of the tape reel in a spray form, and the water causes a slight adhesive force to adhere the wound tapes to each other with a weak adhesive force, thereby causing the tape reel to break. Can be effectively prevented. In the above description, the resistor is constituted by the pressing roll 21. However, as shown in FIG. 8, the resistor is constituted by the fixed body 81 which is in sliding contact with the outer peripheral surface of the tape reel 13, and the fixed body 81 is fixed to the tape reel. Slack is formed on the outermost peripheral tape wound on the tape reel by sliding contact, and the tape tip 11b
May be automatically peeled off to derive and the tape 11 may be supplied continuously. In the above description, the rotating roll 23 that is connected to the electric motor 17 and abuts against the rotating pressing roll 21 is pressed against the tape reel 13 to rotate the tape reel 13, but the chuck is The member is directly rotated by an electric motor to drive the tape reel itself to rotate, and the rotating roll 23 is pressed against the outer peripheral surface of the tape reel to rotate and rotate, and the pressing roll 21 pressed against the rotating roll 23 is In the same manner as described above, the tip of the tape reel can be peeled off from the tape reel even when the tape roll is pressed against the tape reel 13 while being rotated in the opposite direction to the rotating roll 23.
