Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handbag tape attaching device for attaching a tape for a bank to one side of a package having a substantially rectangular parallelepiped outer shape such as a box, and more specifically, a tape for a package to be intermittently transferred. At a position facing the mounting surface, a tape pull-out means for pulling out the tape for a predetermined length along the tape mounting surface, a tape pressure welding means for pressing the pulled-out tape to the tape mounting surface of the package, and a tape for the pressure-welded tape A tape bending means for bending both ends along two surfaces adjacent to the tape mounting surface, and a tape bonding means for bonding both ends of the bent tape to two surfaces adjacent to the tape mounting surface. The one provided and the reel around which the tape is wound are rotatably supported, and a tape pull-out means is provided on the downstream side of the tape feed-out direction from the reel. A predetermined length of tape pulled out by intermittent operation is pressed against the tape mounting surface of the package that has been intermittently transferred, and both ends of the pressure bonded tape are bent along two surfaces adjacent to the tape mounting surface. Regarding what to bond.

[0002]

2. Description of the Related Art Conventionally, as a handheld tape attaching device of this kind, as disclosed in, for example, Japanese Utility Model Publication No. 63-37240, a reel is intermittently transferred to one side of a transfer path through which packages are intermittently transferred. When three tapes are provided and tape withdrawing means are respectively provided on the downstream side of the reels in the tape feeding direction, and when three packages are intermittently transferred to the tape attaching station of the transfer path, each tape withdrawing means causes the tape leading end to end. After sandwiching and pulling downward, the tape drawn by each tape cutting means is cut into a predetermined length, and at the same time, the tape cut by each tape pressing means is pressed against the tape mounting surface of the package, and then each tape After the pulling-out means releases the nipping of the tape tip, each tape folding means moves to project the upper and lower ends of the cut tape to the upper surface of the package. And the tape is bent along the lower surface, and then each tape adhering means is projected and welded while pressing the upper and lower end portions of the tape onto the upper and lower surfaces of the package while pressing the tape into three packages by one operation. There is one that adheres at the same time.

[0003]

However, in such a conventional handheld tape attaching apparatus, the tape is pulled out from a plurality of reels at the same time. However, when the tape is pulled out, the tape is stretched and the tape is wound on the reel. Because the remaining amount of tape is different for each reel due to a slight error in
If any one of the tapes runs out and the reels are replaced, it is necessary to temporarily stop the operation and replace all reels at the same time in consideration of work efficiency. There is a problem that the remaining tape is wasted because the remaining reel is also replaced.

Further, since the tape is cut and pulled out and the tape is bent and adhered to the package at the same station, at least the bending of the tape is completed and the tape pressure welding means and the tape bending means are removed from the package. If the separation is not completed, the tape pull-out means cannot be lifted to start sandwiching or pulling out the next tape, and the tape pull-out operation requires more time than the package transfer time, resulting in low work efficiency. There is a problem that it cannot respond at high speed.

Therefore, as disclosed, for example, in Japanese Utility Model Publication No. 64-1207, there is provided a tape adsorbing and transferring means for adsorbing the upper and lower end portions of the drawn and cut tape and transferring it to the tape mounting station, and mounting the tape by a carry-in conveyor. The packages transferred intermittently to the station are pushed by the pusher in the direction orthogonal to the intermittent transfer direction, and the tape mounting surface is abutted against the upper and lower intermediate parts of the transferred tape, so that the upper and lower ends of the tape Peeled from the suction transfer means, bent and bonded along the upper and lower surfaces of the package, and then the package to which this tape is adhered is sequentially intermittently transferred by the carry-in conveyor and subsequently carried out by the next package. Some push it upwards and transfer it downstream.

However, in the Japanese Utility Model Publication No. 64-1207, a package which is misaligned in the direction orthogonal to the intermittent transfer direction is pushed out to the downstream side by the next package which is intermittently transferred to the tape mounting station. As a result, not only will these packages tend to skew at the time of extrusion, causing malfunction, but the next skewed package will be pushed by the pusher and will hit the upper and lower intermediate portions of the tape, so tape mounting There is a problem that the tape may not be adhered to the correct position on the surface.

Further, since the tape mounting surface abuts the upper and lower intermediate portions of the tape when the package is pushed, and the upper and lower end portions of the tape are peeled off from the tape suction transfer means, a pair of upper and lower suction forces for sucking the upper and lower end portions of the tape. If the entire tape does not contact the upper and lower intermediate portions of the tape at the same time due to slight differences in the tape mounting surface or the tape mounting surface is inclined, the tape will be positioned to the one with strong suction force or the one that partially abuts the tape later. Shift
There is also a problem that the tape cannot be adhered to the correct position.

In view of the above conventional circumstances, the present invention quickly performs pulling out cutting of tape and bending adhesion of tape to a package at separate stations without pushing the package in a direction orthogonal to the intermittent transfer direction. Another purpose is to replace the reel in a short time by using the tape up to the end.

[0009]

In order to solve the above problems, the present invention provides a technical means for rotating a reversing mechanism between a tape mounting surface of a package and a tape drawn by a tape drawing means. The tape is freely provided and inverted by 180 degrees, and a tape attachment surface and a pair of tape holding surfaces facing the drawn tape are arranged back to back in this reversing mechanism, and the drawn tape is moved to these tape holding surfaces. The tape holding surface is supported so that the tape holding surface projects toward the tape mounting surface of the package,
It is characterized in that either one of the tape holding surface is brought into pressure contact with the tape mounting surface and the tape pulling-out means is operated when the tape bending means and the tape adhering means are operated in sequence.

Further, a plurality of reels are provided so as to be capable of reciprocating respectively, and a drive unit for alternately arranging these reels on the upstream side in the tape feeding direction of the tape drawing means is provided in series, and the end of the tape is provided near each reel. Each of the detectors for detection is provided, and the drive section is operated based on the tape end detection signals output from these detectors to separate the reel from which the tape end detection signal is output from the tape pulling-out means. It is characterized in that the reel is moved to the upstream side of the tape pull-out means in the tape feeding direction.

Then, it is preferable to operate the drive portion when the operation of the tape pulling means is stopped.

[0012]

According to the above-mentioned technical means, the present invention holds one tape held by holding one tape held on one tape holding surface immovably and then reversing the reversing mechanism by 180 degrees. One side of the tape faces the tape mounting surface of the package, the other tape holding surface faces the next tape pull-out position, and one tape holding surface holding the tape is pressed against the tape mounting surface so that both ends of the tape While being bent and adhered, the next tape is pulled out along the other tape holding surface.

When the tape is pulled out, the detector detects the end of the tape and actuates the drive section, whereby the reel that has output the tape end detection signal is separated from the tape pulling means, and the spare reel is the tape pulling means. The tape is moved to the upstream side in the tape feeding direction and is replaced with a new tape.

Further, by activating the drive portion when the operation of the tape pull-out means is stopped, the tape is replaced with a new tape by utilizing the timing when the tape pull-out means does not operate.

This drive unit 1f is equipped with both reel holders 1,
1, which is electrically connected to the detectors 1e and 1e, and whose operation is controlled based on the tape end detection signals output from the detectors 1e and 1e, and the tape end detection signal output from either one of the detectors 1e. At the time of inputting the tape, and between the time when the tape cutting means 3 is activated and the time when the tape pull-out means 2 starts to pull out the next tape B, the reel holder 1 to which the tape end detection signal is output is pulled out. Separated from the means 2, another reel holder 1 is moved to the upstream side of the tape cutting means 3 and the tape drawing means 2 in the tape feeding direction, and the tip B of the tape B fed from this is brought close to the clamp 2a.

The tape holding surface 4b of 1 is started to move in the opposite direction and is separated from the tape mounting surface A1.

The operation of the tape pull-out means 2 is controlled at substantially the same timing as the operation of the tape cutting means 3 and the operation of the reversing mechanism 4 and the operation of the tape folding means 5 and the tape adhering means 6 which will be described later. At the same time as the cutting operation of the tape B end B2, the clamp 2a that closes and waits at the lower limit position is opened in the releasing direction of the tape B front end B1, and at the same time as the reversing operation of the tape holding surfaces 4b and 4b, the clamp 2a is moved.
And the clamp 2a is raised to the upper limit position during the pressure contact operation of the tape holding surface 4b, and the clamp 2a is closed in the clamping direction of the tape B tip B1 almost at the same time as the operation of the tape bending means 5 is started. While the tape bonding means 6 is operating, the clamp 2a is lowered to the lower limit position.

The tape folding means 5 is arranged so as to face at least the upper surface A4 and the lower surface A5 of the package A stopped at the tape mounting station D1 and adjacent to the tape mounting surface A1, and the tape B is mounted on the tape mounting surface A1.

The upper end B4 and the lower end B5 of the tape B are welded to the upper surface A4 and the lower surface A5, respectively, by pressing the tape B, and the tape B is released and returned to the standby position at substantially the same time as the next holding operation of the tape B.

On the other hand, in the transfer path D, a chain pusher is provided as a transfer means 7 upstream of the tape mounting station D1, and a stopper intermittently appears on the transfer path D upstream of the chain pusher 7. 8 is provided and the package A supplied from the upstream end of the transfer path D ...
By passing the stopper 8 up and down, the stoppers 8 are passed through the chain pusher 7 one by one at regular intervals, and a carry-out conveyor 9 is arranged on the downstream side of the tape mounting station D1.

The chain pusher 7 is provided with a plurality of push rods 7b ... Along the continuously moving annular chain 7a at appropriate intervals, and the push rod 7b is brought into contact with the package A fed from the stopper 8 to bring it downstream. By pushing the package A toward the side, the package A is rotated about 90 degrees as shown in FIG. 3 to stand up so that the tape attachment surface A1 is in a vertically long shape, and the package A preceding the package A is raised. The tape holding surfaces 4b, 4b are pushed to the tape mounting station D1 almost at the same time when the reversing operation of the tape holding surfaces 4b and 4b is completed, and the preceding package A is carried out of the package A to which the tape B is adhered at the tape mounting station D1. It is pushed out to the conveyor 9 and conveyed to a predetermined location.

Next, the operation of such a handheld tape attaching device will be described.

First, the package A is intermittently transferred to the tape mounting station D1 by the operation of the chain pusher 7 and the stopper 8, and during this intermittent transfer, the pushing plate 4g is projected as shown in FIG. Two
The tape B pulled out by the above is pressed against one tape holding surface 4b, and the tape B is immovably held on the tape holding surface 4b.

Then, the end B2 of the tape B held as shown in FIG. 5B is cut by the tape cutting means 3, and at the same time as this, the clamp 2a of the tape drawing means 2 is opened and the tip of the tape B drawn out. Release B1 and push plate 4
g moves away from the tape B held.

In this state, as shown in FIGS. 4 and 5 (c), the central shaft 4a rotates by 180 degrees and the tape holding surfaces 4b, 4b.
And the clamp 2a of the tape pull-out means 2 starts to rise at substantially the same time as the start of the reversal, and the tape holding surface 4
By the time the reversing operation of b and 4b is completed, the package A to which the tape B is not adhered is the tape attachment station D1.
The tape mounting surface A1 of the package A and the one tape holding surface 4b holding the tape B face each other, and the other tape holding surface 4b faces the pushing plate 4g returned to the standby position.

Thereafter, as shown in FIG. 5 (d), one tape holding surface 4b holding the tape B projects and is pressed against the tape mounting surface A1 of the package A, and at the same time, the clamp 2a of the tape pulling means 2 is pressed. Rises to the upper limit position.

Subsequently, as shown in FIG. 5 (e), the tuckers 5a, 5a of the tape bending means 5 project and move, and the upper end portion B4 and the lower end portion B5 of the tape B held on one tape holding surface 4b. Is bent while being pressed from the upper and lower corners A2, A3 along the upper surface A4 and the lower surface A5, and at the same time, the clamp 2a of the tape pulling-out means 2 holds the tip B1 of the tape B which has been fed next.

Thereafter, as shown in FIG. 5 (f), the heaters 6a, 6a of the tape adhering means 6 are pressed against the upper surface A4 and the lower surface A5 of the package A, and the upper end portion B4 and the lower end portion B5 of the tape B are brought into contact with the upper surface A4. And the lower surface A5 is welded, and at the same time, the clamp 2a of the tape pull-out means 2 descends to the lower limit position to pull out the next tape B.

After the welding is completed, these heaters 6
The a and 6a and the tuckers 5a and 5a are separated from the package A after the tape B is welded and returned to the standby position, and the above-described operation is repeated thereafter.

Further, when the remaining amount of the tape B is gradually reduced by the repetition of the above-mentioned operation and the detector 1e detects the end of the tape B, the end B2 of the tape B is cut and the next tape B is cut. Both reel holders 1 and 1 move until the start of drawing, the reel holder 1 that has output the tape end detection signal separates from the tape drawing means 2, and another reel holder 1 approaches the tape drawing means 2. And replace tape B.

After the tape B is replaced, the empty reel C is removed from the reel holder 1 separated from the tape pull-out means 2.
Remove the tape, attach a new reel C, pull out the tape B wound on this reel C, and dancer roll 1c
And the tip B1 is extended to the feeding portions 1d, 1
If it is sandwiched between d and pulled out to the tape cutting position and set, the tape B is automatically replaced every time the end of the tape B is detected by the detector 1e.

In the embodiment shown above, the tape B made of the thermoplastic resin is welded to the package A wrapped with the thermoplastic resin, but the invention is not limited to this. For example, the surface is made of a material other than the thermoplastic resin. A tape B made of a thermoplastic resin or other material may be adhered to the two surfaces A4 and A5 adjacent to the tape mounting surface A1 of the box by another fixing means such as glue. Two pieces of the package A are arranged in the intermittent transfer direction, but the present invention is not limited to this, and the reel holder 1 may be reciprocally arranged in a direction other than the intermittent transfer direction, or three or more pieces may be arranged.

Further, the reversing mechanism 4, the tape bending means 5, the tape adhering means 6 and the transfer means 7 are not limited to the above-mentioned constitutions, and for example, the central axis 4a of the reversing mechanism 4 is made horizontal and the tape holding surface 4b, 4b is inverted in the vertical direction, or the tape B is pulled out while the tape holding surfaces 4b and 4b are projecting toward the tape mounting surface A1 of the package A without providing the pressing plate 4g, and both tapes are held. If the tape holding surface 4b facing the pulled-out tape B approaches the tape B and holds it immovably by separating the surfaces 4b, 4b from the tape mounting surface A1, the same operation is performed. Other configurations may be used.

[0044]

Since the present invention has the above-mentioned structure, it has the following advantages.

1. By holding the tape pulled out on one tape holding surface immovably and then reversing the reversing mechanism by 180 degrees, one tape holding surface holding the tape faces the tape mounting surface of the package and the other. While the tape holding surface of is facing the next tape pull-out position and one tape holding surface holding the tape is pressed against the tape mounting surface and both ends of the tape are bent and adhered, the next tape Since the tape is pulled out along the other tape holding surface, the tape can be pulled out and cut and the tape can be bent and adhered to the package quickly at separate stations without pushing the package in the direction orthogonal to the intermittent transfer direction.

Therefore, in comparison with the conventional one in which the tape cutting and tape cutting and the tape bending and bonding to the package are performed at the same station, the tape drawing and cutting and the tape tape bending and bonding can be performed at the same time. The efficiency is improved and high-speed handling is possible. In addition, compared to the conventional one, a package that is misaligned in the direction orthogonal to the intermittent transfer direction is pushed out to the downstream side with the next package that is intermittently transferred to the tape mounting station. The tape can be adhered to the tape mounting surface at an accurate position without being tilted, and the tape mounting surface hits the upper and lower intermediate parts of the tape when the package is pushed, and the upper and lower ends of the tape are peeled off from the tape suction transfer means. Compared to the conventional type, the tape holding force is partially different, the tape mounting surface is inclined, etc. Kutomo, tape can be adhered to the tape in the correct position without misalignment.

2. When the tape is pulled out, the detector detects the end of the tape and actuates the drive unit, so that the reel that has output the tape end detection signal is separated from the tape pull-out means, and the spare reel is upstream of the tape pull-out means in the tape feeding direction. Since the tape is moved to the side and replaced with a new tape, the reel can be replaced in a short time by using the end of the tape.

Therefore, the tape is not wasted and it is economical as compared with the conventional one in which the tape is simultaneously drawn from a plurality of reels, and the operation stop time can be shortened to improve the work efficiency.

3. By activating the drive unit when the tape pull-out means stops operating, the tape is replaced with a new tape at the timing when the tape pull-out means does not work, so continuous operation is possible without the need to temporarily stop the operation for tape replacement. And work efficiency is further improved.
