BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a roll tape pull-out apparatus and method according to an embodiment of the present invention. In FIG. 1 to FIG. 3, A is a roll-shaped tape pulling-out device, which includes a tape group 1, a base 2, and a moving body 3.
, Detecting means 4, operating means 5, and guiding means 6.

The tape group 1 is formed by stacking a plurality of tape rolls b wound in a roll shape with the axial direction of the tape rolls b up and down. It is mounted on a pallet 7 to improve transportability.

As shown in FIG. 5, the tape group 1 includes an end terminal b3 of the upper tape roll b and a start terminal b4 of the next lower tape roll b located below the upper tape roll b. Are formed into a continuous tape b1 in which the tape rolls b of each stage are in a continuous state by forming a connection portion b5 with each other by bonding or the like.

.. Are inserted between the tape rolls b, b, b,... To close the paper tube hole b6 at the center of the tape rolls b. This prevents the tape b1 located in the paper tube hole b6 of the tape roll b from dropping along the paper tube hole b6 of the lower tape roll b.

The substrate 2 is provided adjacent to the outer peripheral surface of each tape roll b in the tape group 1. The base 2 is provided on the base plate 8 at the height of the tape group 1 stacked in the predetermined stage. The tape group 1 is formed at a suitable height, that is, substantially vertically above the highest stacked height of the tape group 1. The base 2 guides the moving body 3 described later in a vertical direction in which the moving body 3 moves, and is provided with a sub-base 2a.

The moving body 3 is slidably engaged with the base 2 in the up-down direction, and is configured to always fall by its own weight and fall naturally.

The detection means 4 is attached to the moving body 3 and detects the presence or absence of one tape roll b in the tape group 1. The detection means 4 uses an optical sensor such as a photoelectric tube, a camera sensor, or the like. The control means 9 detects whether or not the tape roll b of the tape group 1 exists at the stop position of the control unit 9 and outputs a detection signal indicating the presence or absence of the tape roll b to the base 2.
Send to

The operating means 5 controls the movement of the moving body 3 on the basis of the detection signal of the detecting means 4 and selects a means capable of controlling the electric operation such as a fluid cylinder or an electromagnetic solenoid. In this embodiment, an air cylinder was used. Then, the cylinder 10 is moved to the moving body 3
A pressing body 12 is attached to the tip of a piston rod 11 that moves forward and backward by pneumatic pressure from a pneumatic source (not shown), and when the piston rod 11 is extended, the pressing body 12 By contact with the sub-base 2a at a predetermined pressure, the movement (down) of the moving body 3 is stopped.

The guide means 6 is attached to the moving body 3 and is mounted on the uppermost tape roll b of the tape group 1 in the diameter direction thereof, and is mounted on the tape roll b of the tape group 1. The tape b1 is always guided to be pulled out from the center of the tape roll b.

The guide means 6 comprises a flexible member 14 having a base fixed to the moving member 3 and a free end attached to a supporting member 13 projecting upward from the tape group 1, a moving member 3 or a supporting member. The flexible body 14 is composed of a drawer guide 15 attached to the base 13 and a fixed drawer guide 15a. The drawer guides 15 and 15a are formed in a ring shape so that the tape b1 passes through the inside of the ring as shown in FIG. 3, and the drawer guide 15 moves up and down together with the movable body 3. Expression
The drawer guide 15a is of a fixed type attached to the base 2, and is finally doubled by the drawer guide 15a.
The triple tape b1 is sent out as one tape b1.

As shown in FIGS. 2 and 3, a pressing means 16 for holding the outer peripheral surfaces of the tape rolls b in a plurality of stages is detachably provided on the outer peripheral portion of the tape group b. That is, the tape b1 in the tape roll b
Is vertically rising along the surface of the adjacent tape b1, but at the drawing end portion (outermost peripheral portion) of the tape b1, the supporting force of the adjacent tape b1 is lost and the tape b1 falls outward. Because it may cause a phenomenon,
By applying the pressing means 16 to the outer peripheral surface of the tape roll b, a support surface for the tape b1 is given and the tape b1
Inconveniences such as tilting are prevented. This holding means 16
Is provided in an arc shape corresponding to the outer diameter of the tape group 1, diagonally or at intervals at at least two or more places, avoiding the corresponding position of the detecting means 4.

Since the moving body 3 is not fixed to the base 2 before the operating means 5 is operated, a manual fixing means 30 is required when preparing the installation of the tape group 1 or the like. For example, as shown in FIG. 4, the fixing means 30 is formed by connecting the sub-base 2 a of the base 2 and the moving body 3 with the connecting pin 31. By pulling out the pin 31 from the pin hole 32 of the moving body 3, the moving body 3 can slide freely.

In FIG. 1, reference numeral 33 denotes a regulating member for detecting the lowering limit of the moving body 3, which stops the take-out means and the like in the next step based on this detection signal.

Accordingly, the embodiment of the roll-shaped tape pull-out apparatus A and the method of the present invention configured as described above has the following effects. First, a tape group 1 is formed and placed on the pallet 7 in such a manner that the tape rolls b are vertically arranged such that the tape rolls are arranged in a plurality of stages, and the axis centers thereof are aligned. Installed in

In the tape group 1, an end terminal b3 of the tape roll b located in the upper stage and a start terminal b4 of the next lower tape roll b located in the lower portion of the upper stage tape roll b are bonded to each other. Connection part b5
To form a series of continuous tapes b1 for each stage.

Then, the flexible member 14 in the guide means 6 is moved to the center of the uppermost tape roll b in the tape group 1.
That is, while being provided so as to correspond to the paper tube hole b6,
A tape b that is viewed through the paper tube hole b6 is passed through the annular drawer guide 15 and is connected via a bypass member 20 to an unillustrated take-out means in the next step.

In this state, when the take-out means is operated, the tape b1 of the uppermost tape roll b in the tape group 1 is fed out from the center of the tape roll b, guided by the guide means 6, and successively. The tape b1 is pulled out in the circumferential direction (outside) of the tape roll b. At this time, the flexible body 1
Since the tape 4 has a function of knocking down the tape b1 which is drawn out of the paper tube hole b6 in a double triple or the like, the tape b1 is smoothly fed to the next step without inconvenience such as entanglement.

When one roll of the tape roll b is pulled out, the detecting means 4 which has detected the outermost peripheral surface of the tape roll b detects the absence of the tape roll b. The pressing body 12 of the rod 11 in the operating means 5 that has been transmitted to the operating means 5 via the means 9 and fixed the moving body 3 to the base 2 retreats and releases the contact. Therefore, since the moving body 3 loses its supporting force,
Fall by its own weight.

However, since the detection means 4 immediately detects the outermost peripheral surface of the next lower tape roll b, this detection signal is transmitted to the operation means 5 through the control means 9 and the rod 11 of the operation means 5 The pressing body 12 is fed out toward the base 2, and the moving body 3 is fixed to the base 2, and the tape roll b at the next lower stage can immediately be prepared for drawing out the tape b1. Therefore, the next lower tape roll b is
Since the start terminal b4 is connected to the end terminal b3 of the tape roll b that has been fed out earlier, the tape b1 is further pulled out continuously without interruption.

Thus, the next lower tape roll b
Is completed, the tape b1 is continuously fed to the next lower tape roll b by the same operation.

[0028]

According to the invention constructed as described above, a large number of tape rolls are provided, the tape start and end of these adjacent tape rolls are respectively joined, and the tape is fed out from the center of the tape roll. By doing so, all the stacked tape rolls are pulled out in a continuous state,
The tape pull-out operation can be performed efficiently, and the operation can be made unmanned. By detachably providing a holding means for holding the outer peripheral surface of the tape roll on the outer peripheral portion of the tape group, it is possible to prevent the tape at the final portion from being tilted at the time of the final drawing of one roll of the tape roll. As a result, the tape can be smoothly pulled out. It has an exceptional effect.
