Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a method of binding with tape, and more specifically, to a method of binding a large number of stacked pieces of paper, etc., using a tape made of paper or synthetic resin. .

<Prior art and problems to be solved by the invention> Conventionally, for stacks of various cards, envelopes, and other pieces of paper, a binding tape made of paper or the like is wrapped around the stack. Afterwards, the ends of the tape are glued.

In order to wrap the binding tape around the object to be bound, an arch-shaped tape guide path is provided on the top of the table of the binding device, and the tip of the binding tape is fed into this tape guide path from the bottom of the table. The binding tape is run around the tape guide path to form a tape loop, and with the object to be bound inserted into this loop,
It is a practice to narrow down the binding tape and wrap it around the object to be bound, and this technique is described, for example, in the Utility Model Act of 1973.
Publication No. 39765, Publication No. 56-4562, Publication No. 4562, Publication No. 4562
-Disclosed in Publication No. 45281, etc.

However, in the above-mentioned prior art, it is necessary to run the binding tape around the tape guide path, so the binding tape may get stuck or caught in the middle of the guide path, resulting in the formation of loops. There is a risk that it will become difficult. Therefore, a special mechanism is required to make the tape run smoothly, and various mechanisms are disclosed in the prior art mentioned above, but in all of them, the tape guide path and binding device become complicated and the manufacturing cost increases. The disadvantage is that it is expensive.

Therefore, as a tape winding technique that eliminates the disadvantages of the arch-shaped tape guide path, the tip of the binding tape is held between swingable arms, and the tape is wrapped around the object by the swing of the arm. A winding technique has also been proposed, and the inventor of the present application proposed this technique in Japanese Patent Application No. 124982/1982 (see Japanese Patent Application Laid-open No. 55811/1983), but the arm operating mechanism is relatively complicated. Therefore, it is difficult to use it in small-sized binding devices, and further improvements have been desired.

<Purpose> The present invention has been made in view of the above problems, and provides a tape binding method that can simplify the tape winding mechanism and downsize the binding device to the extent that it is portable. The purpose is to

<Means for Solving the Problems> In order to achieve the above object, the tape binding method of the present invention includes clamping the leading end of the thermally adhesive binding tape unrolled from the roll with a clamping member, After forming a tape loop by rotating the clamping member approximately once, the tape is further fed out from the unwound using a roller, and the tape is guided along the tape guide member to form a loop of a desired size; After inserting the object to be bound into the loop, contract the loop and wrap the tape around the object,
The winding start side and the winding end side of the tape are thermally bonded together, and a predetermined portion of the tape is cut.

<Example> Next, an example of the present invention will be described below with reference to the drawings.

1 and 2 show the overall structure of the apparatus used to carry out the present invention, 1, 1 is a table, and objects to be bound A, which are made up of accumulated materials such as pieces of paper, are shown.
The front and rear parts of tables 1 and 1 are separated, and table 1 on the front side
is provided so that it can be opened and closed freely, so that the mechanical parts installed inside the lower part of the table 1 can be easily inspected. Note that FIGS. 1 and 2 show a state in which the front table 1 is removed, and the chain double-dashed line in FIG. 2 indicates the position of the front table.

Then, when the front and rear tables 1, 1 are butted against each other, a belt-shaped passage groove 10 is cut out along the seam between the two tables.
A binding tape T, which will be described later, passes through this passage groove 10 to form a loop above the tables 1,1.

Reference numerals 11 and 12 denote guide plates constituting the tape guide member, which are erected at the left and right ends of the passage groove 10 facing each other, and each guide plate 11 and 12 is in contact with the back surface of the tape T. , can guide and hold the tape T. In addition, one guide plate 12
is provided above the roll 13 of the tape T placed at the bottom of the table 1, and the other guide plate 11 is provided at a position away from the roll 13.

The guide plates 11 and 12 are formed in a shape that allows the tape T unwound from the roll 13 to run smoothly and to reliably hold the loop of the tape T above the table 1. That is, the lower part of the table 1 of one guide plate 12 is arranged substantially horizontally directly below the table 1, and the lower part of the table 1 of the other guide plate 11 is inclined diagonally downward and substantially horizontally. The tip of the guide plate 11 is located below the tip of the guide plate 12 (see FIG. 1). Further, among the guide plates 11 and 12, the portions above the table 1 are approximately vertical near the table 1 surface, and are curved inward toward the upper end with a gentle inclination, so that both guide plates The extension lines of the upper ends of 11 and 12 constitute a continuous, gentle arch shape.

Furthermore, 11a and 12a are respective guide plates 11 and 12.
It is a guide frame erected to cover the upper part of the table 1, and its opposing sides are open, and the side surfaces of the guide plates 11 and 12 are covered by the side surfaces. The distance between the side surfaces of the guide frames 11a and 12a is slightly wider than the width of the guide plates 11 and 12, and the height of the guide frames 11a and 12a is approximately the same as that of the guide plates 11 and 12. It has been formed.
Therefore, the guide frames 11a, 12a can protect the guide plates 11, 12, and
The tape T is placed on the guide plates 11 and 12 above the table 1.
When forming a loop along the tape T, the tape T is prevented from shaking back and forth (in the width direction) and coming off the guide plates 11 and 12.

At a predetermined position behind the passage groove 10 of the table 1,
A rectangular receiving plate 2 is embedded flush with the top surface of the table 1. This receiving plate 2 can move forward and backward from inside the table 1 toward the passage groove 10 side, and can be used to sandwich the tape T between itself and a cutting cutter during the operation process described later, or to press the tape T together using the heating press section 5. When the tape T is thermally bonded, it advances toward the passage groove 10 side, and when the tape T is sent out above the table 1 to form a loop, it retreats from the passage groove 10 into the rear table 1. The receiving plate 2 is made of an iron plate or the like so as to be able to withstand high temperatures during thermal bonding of the tapes T together.

Reference numeral 3 denotes a tape running mechanism provided at approximately the center of the lower part of the table 1, directly below the passage groove 10,
A delivery roller 31 rotates in the normal direction (clockwise in FIG. 1) to send out the tape T from 3 toward the guide plate 12.
and this delivery roller 31 and guide plates 11, 12

It is driven by a motor or the like and is fixed to the vertical back plate 1a of the table 1.

Furthermore, auxiliary rollers 33 and 34 that rotate freely are provided directly above each roller 31 and 32, respectively, and these auxiliary rollers 33 and 34 are selected for each of the delivery roller 31 and binding roller 34 immediately below. It is attached to the back plate 1a of the table 1 so as to be able to descend freely so as to come into contact with the target. That is, when feeding the tape T of the unwound 13 from the guide plate 11 to the guide plate 12, one of the auxiliary rollers 31 descends and comes into contact with the feeding roller 31 with the tape T sandwiched therebetween. , when binding the tape T to the object A, contrary to the above, the auxiliary roller 34 descends,
It comes into contact with the binding roller 32 with the tape T sandwiched therebetween. The auxiliary roller 33 and the binding roller 32 are provided with small press rollers 35 and 36 in order to make the tape T run smoothly.

Reference numeral 4 denotes a clamping member that clamps the tip of the tape T, and includes a pair of upper and lower clamping pieces 4a and 4b that can be freely opened and closed and that directly clamps the tape T. It is being That is, the clamping member 4 moves up and down from near the feeding point of the tape T between the feeding roller 31 and the auxiliary roller 35 to near the side of the receiving plate 2 described above, and as it moves up and down, it also clamps the tape. Piece 4a, 4
It rotates approximately once while changing the positional relationship of b upward and downward (see Fig. 6). Further, the clamping member 4 moves back and forth from the back side of the table 1 to the passage groove 10 side.

Next, reference numeral 5 denotes a heating press part for thermally bonding the ends of the tape T, and it is provided movably from an obliquely lower side of the receiving plate 2 to a position where it abuts the lower surface of the receiving plate 2 extending into the passage groove 10. There is. This heating pressing part 5

A support rod 54 connects the tip of the link 51 to the middle of the link 51.
As the link 51 pivots, the heater 53 is moved toward the receiving plate 2 side. Note that an elastic body such as a spring is attached to the support rod 54.
When the heater 53 contacts the lower surface of the receiving plate 2 with the tape T in between, the adhesive surface of the tape T is pressed against the receiving plate 2.
It is designed so that it can be pressed elastically.

Further, below the receiving plate 2, a rotatable cutter plate 21 for cutting tape is provided. This cutter plate 21 turns upward from the hanging state and crosses the passage groove 10, and at this time,
The cutter plate 21 comes into contact with the lower surface of the receiving plate 2, and the end of the tape T can be held between the cutter plate 21 and the receiving plate 2. Then, the end of the tape T held between the cutter plate 21 and the receiving plate 2 is overlapped with the tape T on the unwinding 13 side, which is pressed by the heater 53. After the tapes T are heated to a temperature of
By pivoting downward, the tape T on the unwinding 13 side can be cut.

Each of the above-mentioned operating members is configured to interlock with each other via a link mechanism, a cam mechanism, etc., and a detailed explanation of the operating mechanism will be omitted, but the mechanism is similar to that of a normal binding machine. Adopted. The above device is also provided with an actuation switch, a clutch mechanism, etc., but these are not shown.

As the tape T, use a tape T (Fig. 5) in which thermoplastic resin P is laminated on at least one side of paper or other non-fusible main material t, and the tapes T are overlapped and heated with a heater etc. They can be thermally bonded to each other by heating, and a tape width of about 20 to 50 mm is usually preferred.

Next, the binding method of the present invention using the above-mentioned binding device will be described below with reference to FIGS.

Figures 3 and 4 show the state where one cycle of work process has been completed or the state before starting the work process, and the tape T fed out from the roll 13 is moved by the auxiliary roller in the separated state. 34 and the bundling roller 32, the delivery roller 3 is in contact with the
1 and an auxiliary roller 33.
Then, the leading end of the tape T descends to a position directly above the lower end of the guide plate 11 (hereinafter simply referred to as the lower position), and the clamping member 4 extends toward the passage groove 10 side.
is held in place.

From this state, as shown in FIG. 3A and FIG. After approximately one rotation, the end of the tape T held by the holding member 4 and the unrolled 1
Form a small loop with the tape T on the third side.

Next, as shown in FIG. 3B and FIG. Send it along.
Then, since the end of the tape T is fixed by the clamping member 4, the fed tape T is fixed to the guide plate 1.
1 and the guide plate 12, and can form a large loop above the table 1 along the curved shape of the guide plates 11 and 12. After advancing the receiving plate 2 from the back side of the table 1 to the passage groove 10 side, the object to be bound A is inserted into the center of the loop formed by the tape T, and the receiving plate 2
Place it on top of the

Next, as shown in Fig. 3 (c) and Fig. 4 (c),
The cutter plate 21 is rotated and moved from the back side of the table 1 to a horizontal position crossing the passage groove 10, and the tip of the tape T is held between the cutter plate 21 and the receiving plate 2. After that, the clamping member 4 opens the upper and lower clamping pieces 4a and 4b to release the clamping of the tape T, and then retreats to the back side of the table 1, and then returns to the lower position while rotating once clockwise, and then returns to the lower position. standby state for the work cycle.

Then, at the same time as the auxiliary roller 33 is separated from the delivery roller 31, the other auxiliary roller 34 is lowered and brought into contact with the binding roller 32 while sandwiching the tape T, and in this state, the binding roller 32 is rotated in the reverse direction. , pull back the tape T forming a large loop above the table 1, and place the tape T over the object A.
Tighten the area so that it fits tightly. Note that the binding roller 32 stops rotating after the tape T has been squeezed by the required amount.

Next, as shown in Fig. 3 D and Fig. 4 D,
The clamping member 4 is inserted into the passage groove 10 from the back side of the table 1.
Move it to the side and hold the tape T in the middle.
Further, the heater 53 of the heating press section 5 is brought closer to the lower side of the receiving plate 2.

Then, the end of the tape T held between the receiving plate 2 and the cutter plate 21 (winding start side) and the middle of the tape T that continues from the guide plate 11 to the winding unwinding side 13 side (winding end side) are connected. In the stacked state, the heater 53 is pressed from the lower surface side to thermally bond the tapes T together.

When the heat bonding of the tape T is completed, as shown in FIG. 3E and FIG. The cutter plate 21 that was holding the end of the tape T is rotated downward to unwind 13.
The middle of the tape T connected to the side is cut near the heat-adhesive part, and then the cutter plate 21 is cut through the passage groove 10.
Then return it to the back side of table 1.

Furthermore, as shown in FIGS. 3 and 4, the receiving plate 2 that was sandwiched between the object to be bound A and the tape T is retreated from the passage groove 10 to the back side of the table 1. After completing a series of binding operations, the tape T is placed in a standby state with the clamping members clamping near the ends thereof for the next binding operation.

During the above process, a switch S is provided on the top surface of the table 1 where the objects to be bound A are placed in order to ensure the safety of the binding operation (see FIG. 2). The function of this switch S is that even if one cycle of binding work is completed, while the object A is on the table 1, the object A is placed on the switch S and the switch S is pushed down. In this way, the drive of the motor for feeding out a new tape T, that is, the operation of the feeding roller 31, etc., is not performed. Then, by picking up the bound objects A for which the binding work has been completed from the table 1, the switch S projects back to the upper part of the table 1, enabling the motor and the like to be driven. Therefore,
The above switch S causes the object A to be tied to table 1.
This solves the problem of sending out a new tape T while it is still on top, making it impossible to form a loop, or causing the tape T to become tangled or jammed.

As the objects A to be bound that can be applied to this invention, there can be used various shapes of printed matter such as banknotes, catalogs, lottery tickets, gift certificates, and printed paper. Furthermore, the binding method of the present invention can be applied to items such as seaweed for sushi, which are soft and may be easily damaged by excessive binding force. It can be used safely by adjusting the force, etc.

According to the above-described binding method, the tape T
As a method of wrapping the tape around the object A, one end of the tape T is held and rotated by the holding member 4, and then the tape running mechanism 3 moves the tape T halfway through the passage groove of the table 1. 10, the tape T forms a loop, the object A is inserted into this loop, and then the tape T is pulled by the tape traveling mechanism 3. This makes it possible to eliminate the need for such an arch-shaped tape guide path.

That is, in the conventional binding method, the end of the tape is wrapped around the object to form a loop, so a continuous arch-shaped tape guide path is required to cover the entire circumference of the object. However, in the above embodiment, the ends of the tape T are held by the holding members 4 and the middle of the tape T is inflated to form a loop, so the guide of the tape T regulates the left and right position of the loop. Only the guide plates 11 and 12 are sufficient. Therefore, there is no need for a large arch-shaped guide path, the overall volume of the device is reduced, and there is no need to get in the way when the objects A to be bound are placed on or picked up from the table 1.

Moreover, when the end of the tape is run along the arch-shaped guide path as in the past, the end of the tape or the middle of the tape always runs while sliding along the guide path, so the tape There is a problem that the tape T gets caught in the middle of the guide path or becomes clogged, and in particular, if the end of the tape gets caught in the guide path, it becomes impossible to form a loop. However, in the above embodiment, the tape T Instead of running along the guide plates 11, 12, etc. sequentially from the end, the ends are fixed without moving at all, and the tape T is inflated in the middle to form a loop, and the guide plates 11, 12, etc. 12 is only for regulating the left and right position of the formed loop to ensure that the loop shape is maintained, so the tape T does not run while contacting the guide plates 11 and 12 for a long distance. , the tape T is the guide plate 11,
There is almost no chance of getting caught on 12. In particular, since the end of the tape T does not have to move at all, the problem of the end of the tape T getting caught in a guide path or the like, making it impossible to form a loop, can be completely eliminated.

Therefore, the conventional problem that the tape guide path becomes complicated and bulky due to the need to provide a mechanism for reliably running the tape T in the arch-shaped tape guide path does not occur, and the overall structure of the device can be greatly improved. Can be simplified.

Furthermore, with conventional binding methods, the maximum size of the objects that can be bound is limited by the size of the arched tape guide path, and if the objects are too small compared to the tape guide path, the tape will not work. Since a large loop with a fixed shape is formed, there is a lot of waste and the workability is poor, but with this method, the size of the loop formed by the tape T can be freely adjusted by adjusting the amount of tape T sent above the table 1. It is possible to form a loop of an appropriate size according to the dimensions of the objects to be bound A, which provides excellent flexibility, eliminates waste, and improves workability.

Note that the tape guide member restricts only the left and right end positions of the loop, and leaves the upper part of the loop open; however, this is sufficient to maintain the loop shape, and the upper part is left open. As a result, the bulk of the tape guide mechanism and the entire device are reduced, the weight is also light, and the manufacturing cost of the device is also reduced.

Furthermore, in the embodiment described above, the tape T
The feeding and pulling back of the paper is performed alternately by a feeding roller 31 and a binding roller 32 which are arranged in parallel.
It is also possible to use individual rollers. Further, as a method for cutting the tape T, the cutter plate 21 is rotated from a horizontal state to a vertical state to tear the tape T downward. Groove 1
It is also possible to cut the tape T by providing it so as to be movable back and forth in a horizontal state toward the 0 side, so that the cutter plate 21 cuts the tape T in the width direction.

The device used to carry out this invention may be one that has a structure that includes a clamping mechanism that clamps one end of the tape T and a running mechanism that sends part of the tape T above the table 1 to form a loop with the tape T. For example, in addition to the illustrated operating mechanisms, it is possible to appropriately combine conventional known operating mechanisms.

<Effects of the Invention> As described above, according to the tape binding method of the present invention, after the end portion of the tape fed out from the unwinding is rotated approximately one revolution, the tape is further fed out and the tape is attached to the tape guide member. Since a loop of the desired size is formed by running the tape along the tape, a special mechanism for smoothly running the tape, which was required in the past, can be eliminated, simplifying the structure of the binding device and making it more compact. can be achieved.

In particular, since the loop is formed along the tape guide member, the loop can be reliably formed and the loop shape can be reliably maintained. In other words, simply drawing out a thin, flexible tape from an unrolled tape to form a loop does not ensure the formation of a loop, and it is difficult to maintain the loop shape, causing the problem that the loop collapses or deforms. arise. Furthermore, when inserting an object into the loop, there is a possibility that the object may touch the loop and cause the loop to fall over. However, in this invention, since a loop is formed by aligning a predetermined portion of the tape along the tape guide member, the loop can be repeatedly and reliably formed, and there is no fear that the formed loop will collapse or deform. This has the unique effect of being able to accurately wrap the tape around the objects to be bound, thereby achieving reliable binding work.
