Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bookbinding device that performs bookbinding by heat-bonding a spine tape to the back of a workpiece using a heater;
Especially the spine adhesive f! which can be used for this type of bookbinding device! i/Relating to automatic arrival time adjustment device.

[Prior art]

Conventionally, in this type of bookbinding equipment that uses heat to adhere spine tapes, the user has to adjust the multiple bonding time in advance before binding according to the thickness of the book. This is done by setting the initial adhesion time. Alternatively, some bookbinding apparatuses have no control over the adhesion time of the spine tape.

Manually setting the plastering time in this way is very troublesome for the user, and there is a high possibility that errors in setting the time will cause 4 tubes to be defective. Furthermore, in a single-finger bookbinding device where it is not possible to adjust the adhesion time, differences in adhesive strength may occur depending on the thickness of the object to be bound, and if the thickness of the object to be bound is extremely thick, There was a drawback that the tape attached to the office could peel off due to insufficient i.

[Purpose of the invention]

SUMMARY OF THE INVENTION The present invention aims to eliminate the above-mentioned drawbacks of the prior art by making it possible to automatically adjust the adhesive time of the tape for attaching the spine of the real thing according to the size of the real thing to be produced.

[Development of invention]

In the back tape adhesion time automatic adjustment device according to the present invention,
A detection means for detecting the thickness of the wave-prepared material is provided, a timer is set to an appropriate time by a timer control means in response to a detection signal from the detection means, and a heater control means is set in response to an output signal of the timer. The heater is controlled by As a result, the operating time of the heater is set according to the thickness of the object to be manufactured, and the backing tape adhesion time is automatically adjusted.

〔Effect of the invention〕

According to the present invention, since the adhesion time of the R pasting tape is automatically adjusted according to the age of the genuine product, it is possible to
A constant adhesive strength can always be maintained regardless of the difference in thickness, and therefore problems such as binding defects do not occur.

〔Example〕

A practical example of the present invention will be described below with reference to the drawings.

First, referring to FIG. 1, the workpiece 1 is held clamped from both sides by clamp arms 2.3. The arm 2.3 is slidable in the direction shown by the arrow in order to carry out the above-mentioned tightening operation regardless of the thickness of the object to be manufactured. A light emitting diode 4 is fixed to the clamp arm 2, and a separate member (
(not shown) to the left and right along a guide groove 5 fixed thereto.

Mobile phase phototransistors 6a, 6b, and 6c of the light emitting diode 4 are fixed on the lower side of the guide groove 5, and no matter where the moving light emitting diode 4 is located, at least one of them is connected to the light emitting diode 4. It is designed to receive the output light from.

Phototransistors are given priority and λ
Even if more than two phototransistors are turned on at the same time, the output from the phototransistor with a higher priority is adopted.

A heater 7 is arranged below the workpiece 1 to heat and bond a backing tape to the back surface of the broken workpiece 1.

This heater 7 has a film function that moves as shown by the arrow in order to press the back adhesive tape 8 inserted between the back surface of the workpiece 1 and the heater against the /F surface of the workpiece 1. There is. Reference number 9 is a microswitch that detects when the heater 7 presses the R-applying tape 8 against the back surface of the workpiece 1.

As shown in FIG. 2, a phototransistor 6a.

The outputs of 6b and 6c are timer control Il! 1 circuit 100
It is input to cpυ12 via input port 11.

A memory 13 is connected to the CPU 12, and in this memory 13, the thickness of the broken Korean genuine article is stored.

In FIG. 1, a timer 14 is further provided for setting the adhesive tape adhesion time, and this timer 14
The output of the heater control circuit 1 that controls the operation of the heater 7 is
5 is man-powered.

Next, the operation of the automatic backing tape adhesion time adjusting device according to the present invention will be explained with reference to FIG. In FIG. 1, the light emitting diode 4 moves left and right as the clamp arm 2 moves, but in FIG. 2, for convenience, it is shown as sliding in the vertical direction. When the clamp arms 1 and 2 have completed tightening the workpiece and the light emitting diode 5 has stopped, the phototransistor that has received the light from the light emitting diode 5 is turned on, and its output fi is sent to the human power port 11. is read by the CPU through the memory 1
It is stored within 3. In this way, one copy of the original to be manufactured is stored in the memory 13. When more than one phototransistor is turned on, the CPU 12 reads only the output signal from one of the phototransistors according to its priority order.

Thereafter, when the back pasting operation is started by the heater 7 and the heater 7 is pressed against the back of the workpiece 1, the microswitch 9 is turned on. The output of the microswitch 9 [No. 4] is input to the CPU 12, and starting from the time of this signal input, an appropriate time is selected according to the 11 of the object to be manufactured stored in the memory, and the timer 14 is set to that time. Set to . Incidentally, the following table shows an example of the relationship between the thickness of the workpiece and the adhesion time of the office tape.

When the set time has elapsed, the timer 14 generates an output signal, and in response to this output signal, the heater control circuit 15 terminates the pressing operation of the heater. In this way, it is possible to automatically adjust the JJrl heat time of the backing tape according to the thickness of the object to be manufactured.

In the above-described embodiment, a light emitting diode and a phototransistor are used as means for detecting the thickness of the workpiece to be bound, but instead of these, li! Dynamic resistance, microswitches, etc. can also be used. Further, the number of phototransistors is not limited to three, and can be set arbitrarily. Furthermore, a photosensor may be used as a detection means for pressing the back-attached heater.
