Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a laminator for laminating a laminate object (for example, a restaurant menu) by laminating a laminate film on both sides or one side of the laminate object and applying heat pressure.
[0002]
[Prior art]
FIG. 6 is a diagram showing a conventional laminator.
A conventional laminator 10 includes a film roll 11, a paper feed roller 12, a laminating roller 13, a pulling roller 14, a rotary cutter 15, and a drive motor 16, and performs laminating as follows.
When the laminating operator inserts the laminate object 70 into the laminator 10 one after another, the laminate object 70 is sequentially conveyed by the paper feed roller 12. A sensor A is provided near the outlet of the paper feed roller 12. When the laminate object 70 is detected by the sensor A, the number of pulses is counted by a rotary encoder (not shown) attached to the drive motor 16, and the moving distance of the laminate object 70 is calculated from the number of pulses. The
The paper feed roller 12 conveys the object to be laminated 70 at a speed that is about twice as fast as the speed at which the laminating roller 13 laminates. The reason why the conveying speed of the paper feed roller 12 is high is that the laminating operator needs a certain amount of time to insert the object 70 to be laminated. The laminate object 70 is conveyed at high speed.
[0003]
The object to be laminated 70 conveyed by the paper feed roller 12 is inserted between the two laminated films 11a, and is laminated by being heated and pressed by the laminating roller 13. Then, it is pulled out by the pulling roller 14. In the middle, both side portions of the laminate film 11a are cut by the slitter S.
The rotary cutter 15 has a clutch and can be stopped and operated. When it is detected that the laminate object 70 has reached a predetermined position based on the number of pulses counted by the rotary encoder, the clutch is connected and the rotary cutter 15 is rotated so that the gap between the laminate objects 70 is increased. The laminate film 11a is cut.
[0004]
[Problems to be solved by the invention]
However, since the paper feed roller 12 conveys the lamination target object 70 at a high speed, the lamination target object 70 sometimes floats due to air resistance. Then, the laminate object 70 may stick to the upper laminate film 11a, not between the two laminate films 11a. If it becomes like this, the space | interval with the lamination object 70 immediately before and the lamination object 70 immediately after will go out of order.
In addition, tension is always applied to the laminate film 11a being conveyed so as not to cause wrinkles or the like. Therefore, in particular, the laminate film 11 a heated by the laminate roller 13 is easily stretched by being pulled between the laminate roller 13 and the pulling roller 14. For this reason, even if the movement distance is calculated by the rotary encoder, an error is likely to occur, and the cutting position of the laminate film 11a may vary.
[0005]
An object of the present invention is to provide a laminator that can be inserted between laminated films without causing the laminated object to float, and that does not cause variations in the cutting position of the laminated film.
[0006]

[0009]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a diagram showing an embodiment of a laminator according to the present invention, and FIG. 2 is a diagram showing a state of a cutting process of a laminate product.
In addition, the same code | symbol is attached | subjected to the part which performs the same function as the prior art example mentioned above, and the overlapping description is abbreviate | omitted suitably.
The laminator 10 includes a film roll 11, a paper feed roller 12, a laminating roller 13, a pulling roller 14, a rotary cutter 15, a drive motor 16, a paper feed motor 17, a cutter drive clutch 18, and a conveyance amount measurement. And a roller 19.
[0010]
The film roll 11 is a roll which winds up the laminate film 11a. The laminate film 11a is coated with a heat-sensitive adhesive and can be bonded when heated. Two film rolls 11 are provided for laminating from both surfaces of the laminate object 70.
[0011]
The paper feed roller 12 is a roller that conveys the object 70 to be laminated to the laminate film 11a. The paper feed roller 12 is rotated by a paper feed motor 17 via a drive belt 12a.
The paper feed motor 17 is a stepping motor. As will be described later, when the pulse signal c from the rotary encoder 19a is input to the controller 50, the paper feed motor 17 starts in accordance with the speed of the pulse signal c and feeds the laminate object 70 stepwise. In this way, the pitch P between the lamination objects can always be made constant by sending the lamination object 70 in a timely manner. If this pitch P is set to the length of the sum of the front margin A and the rear margin B of the laminate (that is, P = A + B), the laminate margin can be appropriately reduced by cutting once with the roller cutter 15. (See FIG. 2).
[0012]
Further, a sensor A and a lift prevention plate 12 b are provided downstream of the paper feed roller 12. When the sensor A detects the laminate object 70, the sensor A outputs a detection signal e to the controller 50 (see FIG. 3). The lifting prevention plate 12b is a member that presses the lamination target object 70 from above and prevents the lamination target object 70 from being lifted due to air resistance.
[0013]
The laminating roller 13 is a thermocompression-bonding roller that performs laminating by laminating the laminating film 11a on the laminating object 70 and pressing it while heating. The laminating roller 13 is rotated by a drive motor 16 via a drive chain 16a. A preheating roller 13 a is provided in front of the laminating roller 13. The laminate film 11a is first heated by the preheating roller 13a and then further heated by the laminate roller 13 to perform lamination.
[0014]
The carry amount measuring roller 19 measures the carry amount of the laminate film 11a that is being moved by being pulled by the pulling roller. Further, the carry amount measuring roller 19 receives the slitter S. The slitter S cuts both side portions of the laminate film 11a (see FIG. 2). A rotary encoder 19a (see FIG. 3) is connected to the carry amount measuring roller 19, and a pulse signal c is output in accordance with the rotation (see FIG. 3). The transport amount measuring roller 19 is provided downstream of the cooling fan 20 in the feeding direction of the laminate film 11a. As described above, the reason why the laminate film 11a is provided downstream is to measure the length of the laminated film 11a after cooling because the laminate film 11a is less likely to extend when the temperature is lower than the high temperature state. is there. Further, the cooling fan 20 is separated from the laminating roller 13 so as not to cool the laminating roller 13, and is inclined to the opposite side.
[0015]
The pulling roller 14 is a roller that feeds the laminated film 11 a laminated by the laminating roller 13 to the rotary cutter 15. The pulling roller 14 is rotated by the drive motor 16 via the drive chain 16a. A sensor B is provided in the vicinity of the exit of the pulling roller 14. When the sensor B detects the laminate object 70, the sensor B outputs a detection signal f to the controller 50 (see FIG. 3).
[0016]
The drive motor 16 is a drive source that drives the laminating roller 13, the pulling roller 14, and the cutter driving clutch 18. The drive motor 16 drives the laminating roller 13 and the pulling roller 14 via the drive chain 16a. The drive motor 16 drives the rotary cutter 15 via the cutter drive clutch 18.
[0017]
The cutter drive clutch 18 transmits the rotation of the drive motor 16 to the rotary cutter 15. The cutter drive clutch 18 has a gear 18a, a clutch 18b, and a rotating shaft 18c.
The gear 18a meshes with the gear 16b. The rotation of the gear 18a rotated by the gear 16b is transmitted to the rotating shaft 18c via the clutch 18b. The clutch 18b intermittently transmits the rotation of the gear 18a based on the control signal g of the controller 50, and stops the rotation shaft 18c.
[0018]
The rotary cutter 15 has a blade 15b that is longer than the width of the laminate film 11a and rotates around the rotation shaft 15a. With this blade 15b, the moving laminate film 11a is cut. The rotation shaft 15a rotates when the rotation of the rotation shaft 18c of the cutter drive clutch 18 is transmitted via the drive belt 15c.
[0019]
FIG. 3 is a block diagram showing an embodiment of a laminator according to the present invention.
When the switch SW is turned on, it outputs a signal a.
The drive motor 16 rotates based on the control signal b, and the rotary encoder 19 a that drives the laminating roller 13, the pulling roller 14, and the cutter driving clutch 18 outputs a pulse signal c in accordance with the rotation of the carry amount measuring roller 19. .
The paper feed motor 17 rotates by receiving a control signal d from the controller 50 and drives the paper feed roller 12.
When the sensor A detects the laminate object 70, the sensor A outputs a detection signal e.
When the sensor B detects the laminate object 70, the sensor B outputs a detection signal f.
When receiving the control signal g, the cutter driving clutch 18 rotates the rotary cutter 15 once.
The controller 50 inputs the detection signals e and f from the sensors A and B and the pulse signal c from the rotary encoder 19a. Based on these signals, the controller 50 outputs control signals b, d, and g to control the rotation of the drive motor 16, the paper feed motor 17, and the cutter drive clutch 18.
[0020]
FIG. 4 is a flowchart for explaining the laminator paper feeding process with a focus on the operation of the controller.
When the switch SW is turned on and the signal a is input, the controller 50 starts processing (step (hereinafter referred to as “S”) 101).
First, the controller 50 outputs the control signal b and starts the drive motor 16 (S102). Thereby, the laminating roller 13 and the pulling roller 14 are started, and the laminating film 11a is conveyed. The conveyance amount measuring roller 19 is rotated by the laminate film 11a. At this time, the pulse signal c is output from the rotary encoder 19a, and the controller 50 inputs the pulse signal c (S103).
[0021]
Then, the controller 50 outputs the control signal d1 and starts the paper feed motor 17 (S104).
When the laminate object 70 is inserted into the paper feed roller 12 and detected by the sensor A, the sensor A outputs a detection signal e. When the controller 50 inputs the detection signal e (S105), the controller 50 outputs a control signal d2 and stops the paper feed motor 17 (S106).
[0022]
When the controller 50 determines that the count of the pulse signal c from the rotary encoder 19a has reached a predetermined number and the transport amount of the laminate film 11a has reached a predetermined amount (S107), the controller 50 outputs a control signal d3, and the paper feed motor 17 Is activated (S108). When the count of the pulse signal c from the rotary encoder 19a reaches a predetermined number (S109), the controller 50 outputs a control signal d4, decelerates the rotation speed of the paper feed motor 17, and conveys the laminate object 70. The speed is adjusted to the speed at which the laminating roller 13 transports the laminating film 11a (S110).
[0023]
Further, when the controller 50 determines that the count of the pulse signal c from the rotary encoder 19a has reached a predetermined number and has reached the position where the laminate object 70 is sandwiched between the laminate films 11a (S111), the controller 50 outputs a control signal d5. Then, the rotation speed of the paper feed motor 17 is restored (S112), and the process returns to S105 again.
[0024]
FIG. 5 is a flowchart for explaining the laminator disconnection process, focusing on the operation of the controller.
When the laminate object 70 laminated with the laminate film 11a drawn from the pulling roller 14 is detected by the sensor B, the sensor B outputs a detection signal f. After the controller 50 inputs the detection signal f (S201), the controller 50 determines that the count of the pulse signal c from the rotary encoder 19a has reached a predetermined number and the laminate object 70 has approached the rotary cutter 15 (S202). 50 outputs the control signal g, starts the cutter drive clutch 18, and cuts the laminate film 11a between the laminate objects 70 with the rotary cutter 15 (S203).
[0025]
According to this embodiment, since the speed of the lamination target object 70 is reduced and applied to the laminate film 11a, it is possible to prevent the lamination target object 70 from being lifted due to air resistance.
Moreover, since the lamination target object 70 is decelerated to substantially the same speed as the laminate film 11a and matched with the laminate film 11a, wrinkles and the like that occur when the speeds are different can be prevented.
Furthermore, since the anti-lift plate 12b is provided, it is possible to further prevent the lift.
Furthermore, since the amount that the laminate film 11a has passed by the transport amount measuring roller 19 is directly measured, the space between the laminate objects 70 can be accurately cut.
[0026]
(Deformation)
The present invention is not limited to the embodiment described above, and various modifications and changes are possible, and these are also within the equivalent scope of the present invention.
For example, in the above embodiment, the case where the lamination is performed on both surfaces of the object to be laminated has been described as an example, but the lamination may be performed only on one surface. In this case, only one film roll 11 may be used.
[0027]
【The invention's effect】
As described above in detail, the present invention has the following effects.
(1) When the object to be laminated comes close to the laminate film, the conveying speed of the object to be laminated is reduced, and the object to be laminated is conveyed at a speed almost equal to the speed at which the laminating means laminates. Can be prevented.
[0028]
(2) Since the anti-floating means for preventing the laminate object from being lifted by pressing the laminate object conveyed by the conveying means is provided, it is possible to further prevent the laminate object from floating.
[0029]
(3) Since the laminate means includes a length measuring means for measuring the length of the laminated film laminated and a cutting means for cutting the laminate film based on the length measured by the length measuring means, the accurate position is obtained. The laminate film can be cut.
