Description

  The present invention relates to a label sticking apparatus for sticking a label to a product or its packaging, and relates to a label sticking apparatus provided with a control device that can easily perform label stop position alignment.

Conventionally, in this type of label applicator, the label stop position is adjusted by moving the position of the label detection sensor each time depending on the shape of the label or changing the distance from the tip of the label peeling plate to the label detection sensor. The position of the label detection sensor is adjusted so that the gap between the label and the label goes to the tip of the label peeling plate (for example, see Patent Document 1).

Further, the label feeding delay switch 22 is used to delay the time for starting the board feeding after detecting the product, and to move the sticking position to the product backward. In addition, the unpaid label mount 3 and the label mount D from which the label E has been peeled off from the original fabric portion 1 to the take-up portion 6 are guided by a guide roller in the same manner as a conventional label sticking device. .

The control device 30 that performs label auto-tuning for easily performing label stop positioning is configured to control each part of the pulse motor 39 and the like for winding the label mount D by a microcomputer 31 configured by the CPU 35 and the like. Has been.
The control device 30 that performs label auto-tuning in FIG. 7 is provided with a CPU 35 that executes various arithmetic processes and centrally controls each unit. The CPU 35 includes a ROM 32 that stores fixed data fixedly, and a variable. A RAM 33 that stores data in a rewritable manner is connected via a system bus 36. The ROM 32 stores a control program, and the microcomputer 31 executes various processes according to the control program stored in the ROM 32 while using the RAM 33 as a work area.
The control device 30 is detected by, for example, a registration unit that registers the distance L from the label peeling unit 9 at the tip of the label peeling unit 8 to the label detection sensor 5 (in this example, the ROM 32) and the label detection sensor 5. A pulse number management unit (using the CPU 35 in this example) for managing the number of pulses output to the pulse motor 39 of the winding unit 6 at each leading end A of each label E and each trailing end B of the label E; The leading end A and the trailing end of the label E based on the number of pulses output to the pulse motor 39 of the winding unit 6 at the leading end A of each label E and the trailing end B of each label E managed by the number management unit. The margin length Q and the label length C between B and B are calculated, the distance L from the label peeling portion 9 to the label detection sensor 5 at the tip of the label peeling plate 8 registered in advance in the registration portion, and the margin length Q is compared with the label length C, and the winding length of the label mount for one cycle (margin length Q + label length C) is calculated to determine the winding length of the label mount for one cycle. A calculation unit (in this example, the CPU 35 is used), a memory 34 for registering the winding length of the label mount of one cycle determined by the calculation unit, and a winding length of the label mount of one cycle determined by the calculation unit And a feed amount control unit (in this example, using a CPU 35) for controlling the pulse motor 39 so that the label A at the front end of the label E is stopped at the label peeling unit 9 at the front end of the label peeling plate 8.

The control device for winding the label E is provided with a motor driver 37 for driving and controlling a pulse motor 39 for winding the label mount D as a part of the microcomputer 31 that is driven and controlled. The motor driver 37 is connected to the CPU 35 via the system bus 36. The CPU 35 controls the motor driver 37 by pulse output, and the advance amount of the pulse motor 39 is managed by the number of pulses.
The control device that detects the label E connects the label detection sensor 5 to the system bus 36 via the I / O port 38. Then, the gap Q between the label E and the label E of the unfeed label mount 3 on which the plurality of labels E are adhered with a predetermined interval (corresponding to the gap Q between the labels E and E) is detected. .
The test switch 21 is connected to the system bus 36 via the I / O port 38, and when the test switch 21 is pressed, the initial setting of the label E is started.

Next, the mechanism of the initial setting control by the label sticking apparatus according to the present embodiment will be described with reference to FIGS.
The unpaid label mount 3 is attached to the label sticking apparatus according to this embodiment, and power is supplied (step S1). When the operation switch 20 is turned on, the label auto-tuning control device 30 enters the labeler auto-tuning mode (step S2).
When the test switch 21 is pressed (step S3), the mount D is wound around the winding unit 6 by the feed roller (label feed roller) 7 driven by the pulse motor 39 (step S4). At that time, the label detection sensor 5 detects the rear end B of the label E, the front end A of the label E, the label E, and the rear end B of the label E as shown in FIG. During this operation, the CPU 35 manages the number of pulses output to the pulse motor 39 at each position. The CPU 35 calculates the margin length Q and label length C between the rear end B of the first label E and the front end A of the label E based on the number of movement pulses.
The CPU 35 then registers the distance L from the label peeling portion 9 at the tip of the label peeling plate 8 registered in advance in the ROM 32 to the label detection sensor 5 and the distance between the rear end B of the label E and the tip A of the label E. The margin length Q and the label length C are compared and calculated. Further, the winding length of the label mount D for one cycle (the margin length Q + the label length C between the rear end B of the label E and the front end A of the label E) is calculated, and the label mount D of one cycle is calculated. The winding length is determined (step S5), registered in the memory 34 (step S6), and the pulse motor 39 is controlled so that the leading edge of the label E stops at the label peeling portion 9 at the leading edge of the label peeling plate 8 to feed The roller (label feeding roller) 7 is driven to wind the label mount D around the winding unit 6 (see FIG. 4).
This completes the initial labeler auto-tuning (step S7).
When the operation switch 20 is turned on again, the label sticking device enters the mount feeding signal standby state. By inputting the feeding signal, for example, as shown in FIG. Can be pasted.

The above describes the operation from the state in which the test switch 21 is pressed with the label E on the label detection sensor 5 based on FIG. 4, but the state in which the label detection sensor 5 has no label E as shown in FIG. When the test switch 21 is pressed, the label detection sensor 5 detects the leading edge A of the label E, the label E, the trailing edge B of the label E, and the leading edge A of the label E in this order. During this operation, the CPU 35 manages the number of pulses output to the pulse motor 39 at each position.
In the label sticking device according to the present embodiment, the tip portion can be simplified and the stop position can be easily adjusted, so that the label return can be inserted into a narrow gap. For this reason, it can be used for lower surface bonding and side surface bonding regardless of only upper surface bonding.
Further, since the length C and the margin length Q of the label E can be registered in the memory 34, an abnormality can be output instantaneously as an alarm even when the missing tooth of the label E occurs.

Next, referring to FIGS. 8 to 10, for example, the distance L from the label peeling portion 9 that becomes the label return to the label detection sensor 5 is 100 mm, the label length C is 25 mm, the margin length Q is 5 mm, and the label E Will be described as labels E1, E2, E3, and E4.

(5) The CPU 35 compares the distance L = 100 mm from the label peeling portion 9 that is the label return registered in advance in the ROM 32 to the label detection sensor 5 and advances 10 mm after detecting the label leading end A of the label E3. The pulse motor 39 is controlled to stop at the position, and the feed roller (label feeding roller) 7 is driven to wind the label mount D around the winding unit 6.
