Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Application of the Invention) The present invention relates to a winding cassette for winding and storing tape-like labels loaded into a portable labeling machine.

(Prior art) Conventionally, the cassette case type label winding system for this type of portable labeling machine was developed by Japanese Patent Publication No. 54-16400 (
Manual label printing and pasting machine) and Special Publication No. 57-4453
4 (manual labeling device), etc.

However, since both of the above technologies use a label printing and pasting machine, that is, printing on labels is performed using a printing device installed in this machine, especially in the print head installed in this machine that prints barcodes for PO5. Since the barcode is read by an optical reader, strict accuracy is required for the length and spacing of the barcode, but there may be structural errors in the print head itself or excess or insufficient ink applied to the typeface. etc.,
Barcodes were often not printed accurately and could not be read correctly. Additionally, barcode printheads are inevitably larger than normal character printheads due to the size of the standardized z<- code, and as a result, the /% labeler is also large and heavy. This also increases worker fatigue, and since barcode printing is different from numbers and letters and is difficult for general workers to read, it is easy to use barcode labels printed for other products by mistake. I often ended up pasting them.

Furthermore, barcodes require a check digit, but because of the size and structural limitations of hand labelers, it is difficult to provide an automatic calculation function for the check digit. This was also inconvenient.

Hand labelers for barcodes have the above problems, so after printing on a continuous label using a stationary printer, the printed labels must be manually peeled off one by one from the backing paper of the continuous label. However, this manual method significantly reduces the speed of label application, resulting in poor work efficiency, and the printing on the label surface may be rubbed off by fingertips during application. However, there has been a demand for the development of an apparatus that can accurately and efficiently print and affix barcode labels.

(Object of the invention) The present invention was proposed in view of the above-mentioned circumstances.
Clear the desired information in advance using a stationary printer.
and rapidly printed label continuum.

To provide a winding cassette configured to wind up and store in a roll shape.

(Summary of the Invention) The winding cassette of the present invention includes a winding mechanism that winds up a continuous label body in which labels are successively temporarily attached to a tape-like mount;
It is equipped with an engaging part that is attached to a printer and a label pasting machine, and the winding mechanism winds up a continuous label printed by a stationary printer, and the engaging part can be attached to and detached from the printer and label pasting machine with a single touch. This is what I did.

(Example) The winding cassette 2 of the present invention will be described below with reference to an example shown in the drawings.

With reference to FIGS. 1 and 2, the winding cassette 2 of the present invention
is constructed in the form of a cassette that can be attached to and removed from the printer 1 and the label pasting machine 3, and has a winding mechanism 33 rotatably provided in the center of the machine frame 32, and an engagement notch 34 in the lower center. A pair of engagement pieces 35 are formed in a protruding manner. Roughly installed inside the rear end are a rechargeable battery 36, a memory circuit 37 for storing the content and number of copies printed by the printer 1, and a connector 38 for inputting and outputting them.

To explain the winding mechanism 33, one side of the machine frame 32 has a
Engagement unevenness 24 of the transmission shaft 22 is provided at one end of the printer 1.
The rotating shaft 4 is formed with radial engagement unevenness 39 that engages with the rotating shaft 4.
0 is rotatably fitted, and the adjustment shaft 41 is fitted to the other machine frame 32.
are rotatably fitted. An adjustment screw 42 is threaded through the center of the adjustment shaft 41, and the tip of the adjustment screw 4z is screwed into a screw hole 43 bored at the center of the five-rotation shaft 40. Note that a cylindrical winding core 44 is supported on the inner periphery of the rotating shaft 40 and the adjusting shaft 41.

At four locations on the outer periphery of the core 44, there are label continuum 6 (fifth
A clamping spring 45 is provided to clamp and stop the tip of the shaft (see figure), and an annular friction rubber 46 is fitted on one end surface, that is, the contact surface with the rotating shaft 40. A sleeve 47 is fitted to the outer periphery of the narrow diameter portion at the tip of the rotating shaft 40, and a pressure adjustment spring 49 is inserted between the tip surface of the adjustment shaft 41 and a flange 48 formed at one end of the sleeve 47. is delivered, and the friction rubber 46 of the winding core 44 is always pressed against the rotating shaft 40. That is, a slip mechanism using friction rubber 46 is provided between the rotating shaft 40 and the core 44, and the pressing force between the two can be adjusted using the adjusting screw 42. Therefore, as the outer diameter of the label continuous body 6 that is wound around the winding core 44 that rotates in synchronization with the platen roll 9 increases during label winding, the core 44 becomes more spaced relative to the rotating shaft 40.

The amount of rotation can be adjusted by lipping.

Furthermore, an elastic piece 97 having a label holding part 98 formed at its tip is attached to the upper end of the winding cassette 2.
The label pressing portion 98 is configured to lightly press the outer periphery of the wound continuous label body 6 so that it does not unravel and does not interfere with the transportation of the continuous label body 6.

Next, the winding cassette 2 of the present invention is configured to be detachably attached to the printer 1 and the label pasting machine 3.

In FIG. 1, the printer 1 prints predetermined characters on labels and sends them out of the machine.

The printing mechanism and transfer mechanism are based on known means, but in this embodiment, a thermal printing type thermal printing device (thermal printer) is used. That is, a continuous label body 6 in which labels 4 are sequentially temporarily attached to one side of a tape-shaped mount 5 shown in FIG. After the label 4 is printed on the platen roll 9, the thermal transfer ribbon 7 is separated and wound up separately, and the label continuous body 6 is passed through the turning pin 10 and transferred to the winding cassette 2 set at the top of the printer 1. It is configured to be rolled up.

The use of a thermal printer eliminates the problem of noise generation due to stamping sound during printing, and also provides excellent printing performance, making it particularly suitable for barcode printing.

The mounting portion 11 of the printer 1 in which the winding cassette 2 is removably set will be explained with reference to FIGS. , the center part is a deeper engagement recess 1

Further, a support stand 21 is erected on one side of the mounting stand 12, and a transmission shaft 22 passes through the upper part of the support stand 21. The transmission shaft 22
A knob 23 is formed on one end, and radial engagement unevenness 24 is formed on the other end surface, and a pulley 25 is attached inside the support base 21 at the center, and the pulley 25 and the platen roll 9 are connected to each other. A belt 27 is stretched between the pulley 26 and a pulley 26 that is coaxially attached.

Furthermore, an annular protrusion 28 is provided on one side of the support base 21, and an annular protrusion 29 that protrudes from the outer periphery of one end of the transmission shaft 22 toward the other end is fitted into the protrusion 28. A pressing spring 84 is housed in the space formed by the re-annular convex portions 28, 29, and biases the transmission shaft 22 to the right in FIG.

Further, an annular member 31 fixed to the removal lever 18 having a knob 30 formed at the upper end is fitted onto the outer periphery of the annular convex portion 28 .

Incidentally, above the platen roll 9, a label cutting mechanism 90 consisting of a cutting lever 92 with a cutting blade 91 is provided.

Next, the labeling machine 3 will be explained with reference to FIGS. 3 and 4. The label applicator 3 detachably attaches the winding cassette 2 to the label continuum 6 wound around the core 44.
Pull out the label 4 from the mount 5 and remove the label 4.
This is a device for attaching a winding cassette 2 to an article, and a mounting recess 50 in which the winding cassette 2 is set is formed in the upper center of the device.

The center part of the mounting recess 50 is the engagement piece 35 of the winding cassette 2.
A deep engagement recess 51 is formed so that a spring 54 can be inserted thereinto, and at the front end of the engagement recess 51, an engagement pin 53 inserted across a pair of elongated holes 52 bored in the machine frame on both sides is inserted into a spring 54. It is always urged backwards and protrudes. Note that removal knobs 87 are attached to the outside of the machine frame at both ends of the bin 53. In addition, a winding cassette 2 is provided at the rear of the mounting recess 50.
Connector 5 connected to connector 38 (see Figure 1) of
5 is installed. Further, the front bottom of the mounting recess 50 has a label passage 5 formed by a pair of guides 56 and 57.
8 is communicating downward.

A grip 59 is formed as an integral extension at the rear of the labeling machine 3, and below the grip 59, a hand lever 61 biased clockwise by a return spring 60 is rotatable to the machine frame by a main shaft 62. It is pivoted. Further, a microswitch 63 for issuing a label is installed inside the grip 59, and a protrusion 64 for operating the microswitch is formed on the hand lever 61 at a position corresponding to the switch 63.

A label transport mechanism 65 is provided in the center of the label applicator 3. Specifically, a claw member 68 with a gear 67 integrally formed thereon, and a transfer roller 70 with transfer claws 69 provided at regular intervals on the outer periphery are rotatably mounted on the shaft 66.
A platen 71 is rotatably attached to the shaft 66.

Engagement steps 72 are formed at regular intervals on the inner peripheral surface of one side of the rim of the transfer roller 70, and the claw member 68 is provided with a pair of claws 73 made of an elastic material. Therefore, when the hand lever 61 is gripped, the gear 74 formed at the tip of the lever 61 meshes with the gear 67 of the pawl member 68 to rotate the pawl member 68 clockwise. The roller 70 slides on the inner peripheral surface of the rim and is locked to the locking step 72.Next, when the hand lever 61 is released, the claw member 68 rotates counterclockwise due to the meshing of the gears 67 and 74. , the claw 73 rotates the transfer roller 70 counterclockwise by a certain angle. In addition, 99 in Figure 3
A reversal prevention member made of an elastic material engages with a recess (not shown) K formed on the inner circumferential surface of the rim of the transfer roller 70 to prevent the roller 70 from rotating in the opposite direction.

Next, on the front part of the label pasting machine 3, there are boards 75.7 on the top and bottom.
6 are provided on the upper substrate 75, a display 77, a issuing lamp 78 . Push button 79 and connector 80 are connected,

Further, the connectors 80 and 83, the connector 55 of the mounting recess 50, and the label issuing microswitch 63 are connected to each other by lead wires. Note that a storage section 100 is formed in the display board 86 in front of the display 77.

The display device 77 is, for example, a light emitting diode display device, and displays information such as the printed content and number of labels stored in the storage circuit 37 (see FIG. 1) of the winding cassette 2 through the detection of the sensor 82 or the push button. The issuance lamp 78 is turned on only when the printing information of the label currently being issued is displayed on the display 77, and is turned off in other cases. There is. Further, the push button 79 is used to confirm the print information stored in the memory circuit, and by pressing this button one after another, all the print information is sequentially displayed on the display 77. The sensor 82 detects the mark 85 printed on the label 4 as shown in FIG. Count. The control unit 81 includes the above memory circuit 37. Micro switch 63, sensor 8
2. Controls the relationship among the display 77, issue lamp 78, and pushbutton 79.

The operation of this embodiment will be explained using bar code printing as an example with reference to FIGS. 1 and 2. First, the winding cassette 2 is set on the mounting base 12 in the printer 1. That is, while connecting the connectors 20 and 38, the engaging piece 35 of the winding cassette 2 is inserted into the engaging recess 14 of the mounting base 12, and the retaining bottle is locked in the engaging notch 34. Note that with this set, charging of the battery 36 is started, and the engagement unevenness 24 of the transmission shaft 22 and the engagement unevenness 39 of the rotating shaft 40 are engaged.

Next, the label continuous body 6 is fed in the printer 1, and the tip of the fed-out label continuous body 6 is held between the clamping springs 45 of the winding core 44. Input the print information A, that is, the print contents (product code, price, check digit, etc.) and the number of print sheets. Note that this input information A is simultaneously transferred to the storage circuit 37 of the winding member 2 and stored therein.

Then, when printing starts, barcodes are printed on the set number of labels 4 by the thermal head 8.
The continuous label body 6 is transported by the rotation of the platen roller 9. At that time, the rotation of the platen roller 9 is controlled by the pulley 26,
Since the power is transmitted to the transmission shaft 22 via the belt 27 and the pulley 25, the rotating shaft 40 also rotates in synchronization due to the engagement between the engaging projections 24 and 39, and is suppressed via the rotating shaft 40 and the friction rubber 46. The winding core 44 in contact also rotates at the same speed to wind up the continuous label body 6.

When the printing of this printing information A is completed, the next printing information B is input and printing and winding are performed, and in the same manner, printing of all predetermined printing information C, D, . . . H is performed.

Note that all of the print information A, B, C, . . . ΦH is stored in the storage circuit 37. Furthermore, in the above printing, in addition to printing a predetermined bar code, a mark 85 is printed at a predetermined position of each label 4, for example, at each end (see Fig. 5).
.

Further, during the winding, as the winding diameter of the core 44 increases, the core 44 slips due to the slip mechanism, so that the winding can be performed without any trouble.

When all printing is completed or the amount of winding in the winding cassette 2 reaches a predetermined limit, printing stops and the label is automatically fed. When the predetermined number of blank feeds are completed, the label continuous body 6 is cut by the cutting blade 91 of the label cutting mechanism 90.Then, the winding member 2 is removed from the printer 1, that is, the irIth! Remove lever 18 at I
Rotate the knob 30 clockwise to remove the engagement pin 16 from the engagement notch 34 of the winding cassette 2.
All you have to do is lift it.

Next, this winding cassette 2 is set in the mounting recess 50 of the labeling machine 3 shown in FIG. That is, the engaging piece 3 is connected while connecting the connector 38 (see FIG. 1) and 55.
5 into the engagement recess 51 to lock the notch 34 to the bottle 53. Then, the end of the label continuous body 6 is pulled out from the winding cassette 2 and inserted into the label passage 58, and the bottom cover 89 and platen 71 of the label 3 are opened as shown in FIG. After turning backward in front of the turning bin 71a provided at the tip of the platen 71 and engaging the notch 5a of the mount 5 with the transfer claw 69 of the transfer roller 70, the platen 71 and bottom cover 89 are set as before. .

To issue a label, first grasp the hand lever 61, which turns on the microswitch 63, which turns on the battery 36 in the take-up cassette 2.Next, when the hand lever 61 is released, the claw 73 turns on. The rotation causes the transfer roller 70 to rotate counterclockwise by -pitch, and at the same time, the mount 5 is pulled rearward by the transfer claw 69. At this time, the label 4 temporarily attached to the backing paper is peeled off from the backing paper 5 at the position of the turning bin 71t and sent out below the pasting roller 88. Initially, a blank label is fed out by the printer 1, but as the hand lever is repeatedly grasped and released, the mark 85 on the printed label 4 is eventually detected by the sensor 82, and the indicator 77 and issue lamp 78 turns on. In that case, the label 4 is sent in the reverse order in which it was wound up, that is, in the order of printed information H, G...A, so the display 77 also displays printed information H, G...A. Memory circuit 37 in order
It is also controlled to be transferred.

The display 77 displays the print content of each print information and the number of sheets in numbers, and the label 4 is displayed by operating the hand lever 61.
Each time a sheet is printed, the sensor 82 detects the mark and decreases the number of sheets displayed by -, and print information H.
When the number of sheets displayed becomes 0, it automatically switches to the print content and number of sheets of print information G. In addition, press button 7 on the way.
If you press 9, the issuance lamp 78 goes out and the display 7
The display at 7 also changes to the next print information, and by pressing the push button 79 one after another, all stored print information can be confirmed. When the display returns to the label currently being issued, the issue lamp 78 lights up again.

The label 4 is pasted on the article, as with a normal hand labeler, on the bottom surface of the label below the pasting roller 88 (
By applying the adhesive surface (adhesive surface) to the article and rubbing it, the adhesive can be attached by the action of the attaching roller 88.

In addition, the control unit 81 is provided with a power saving mechanism using a timer, and if the hand lever 61 is not operated for a certain period of time, the battery 36 is turned off, and the indicator 77 and indicator lamp 78 are turned off.
is now turned off.

Note that in this embodiment, the printing order in the printer 1, that is, the reverse order of the winding order in the winding cassette 2 H, G.
・A label is issued at A, but by rewinding it with an appropriate rewind mechanism, the printing order is changed to A, B, etc.
It is also possible to configure the printing order to be issued in H and display on the display 77 in the printing order.

(Effects of the Invention) The winding cassette of the present invention has a winding mechanism that allows a stationary printer to wind a continuous label with accurate and clearly printed labels, and the effect is particularly noticeable in the case of barcode printing. be. Furthermore, the engagement portion consisting of the engagement piece of the engagement notch material allows for one-touch engagement and disengagement with the printer and label pasting machine. Therefore, unlike general label printing and pasting machines, printing equipment and platens are not required, so the advent of this take-up cassette allows label pasting machines to be made smaller and lighter, reducing operator fatigue and increasing pasting speed. It has advantages such as:
