Japanese Patent No. 3022360

  The present invention has been made in view of the above-described problems of the prior art, and the problem is that even if a pressing roller that presses the belt-shaped mount against the feed roller is provided, the pressing roller is switched between contact and separation. It is an object of the present invention to provide a label issuing device that can be easily performed with a small force.

In order to solve the above-mentioned problems, the label issuing device of the present invention is a label issuing device that peels off a label attached to a strip mount so as to be peeled off from the strip mount at a peeling portion disposed on the transport path of the strip mount and issues a label. In the apparatus, a feed roller that pulls out and conveys the belt-like mount from the label supply unit, a first roller and a second roller that wind the belt-like mount around the outer peripheral surface of the feed roller, and the first roller and the second roller are supported. When the first roller moves away from the feed roller due to the tension of the belt-like mount, the second roller is swung so as to be pressed against the outer peripheral surface of the feed roller, and the swing member is swung. And an opening / closing mechanism that pivotally supports the first roller and the second roller so as to switch the approach and separation of the first roller and the second roller with respect to the feed roller. Claim 1).
The label issuing device has a printing function, a label printer that prints a predetermined matter on a label paper affixed to a strip mount and peels off and issues the label, and a label on which the predetermined matter is printed is peeled off on the strip mount It includes both a label issuing device that can be attached and peels off the label from the belt-like mount and issues it.

  In the separated state (open state), the opening / closing mechanism has the belt-like shape between the outer peripheral surface of the feed roller and the outer peripheral surface of the first roller, or between the outer peripheral surface of the feed roller and the outer peripheral surface of the second roller. The insertion of the mount is possible, and in the approaching state (closed state), the first roller and the second roller are positioned so as to wrap the belt-like mount around the outer peripheral surface of the feed roller more than half a circle. ).

Further, the swinging member pivotally supported by the opening / closing mechanism biases the second roller supported by the swinging member in a direction in which the second roller is pressed against the outer peripheral surface of the feed roller. (Claim 3)
As the urging means, for example, a coil spring is generally used and is mounted across the opening / closing mechanism and the swing member.

In addition, the first roller and the second roller that act to wrap the belt-like mount around the outer peripheral surface of the feed roller more than half are not required to move, and only one of the rollers, for example, the second roller is movable. You may do it.
Specifically, one roller (first roller) is fixed to the opening / closing mechanism, and the other roller (second roller) is pivotally supported so as to be movable with respect to the opening / closing mechanism. The direction is different from the separation switching direction.
As its configuration, the swinging member is pivotally supported with respect to the opening / closing mechanism and the second roller is attached to the swinging member, or the second roller is directly attached to the opening / closing mechanism to be movable , etc. Either may be used.
The first roller, the second roller in the present invention, the upstream side of the first roller from the feed roller with respect to the transport direction of the backing strip, the downstream side means the second roller.

According to the means of claims 1 to 3, the belt-like mount is set so as to be wound around the mount take-up shaft between the first roller and the feed roller and between the second roller and the feed roller. When the tension of the set strip-shaped mount acts on the first roller, the swinging member that supports the first roller and the second roller swings due to the tension, and the first roller separates from the feed roller. The two rollers approach the feed roller and press the belt-like mount against the outer peripheral surface of the feed roller. Thereby, the urging force (spring force) of the pressing rollers (first roller, second roller) that presses the belt-like mount against the outer peripheral surface of the feed roller can be made weaker than before. As a result, the opening operation of the opening / closing mechanism for separating the first roller and the second roller from the feed roller can be lightly performed with a small force.
Since the belt-like mount is wound around the outer peripheral surface of the feed roller by the first roller and the second roller, the contact area between the feed roller and the belt-like mount can be widened, and the belt-like mount can be strongly conveyed by contact friction. it can.

  According to the fourth aspect of the present invention, the switching direction of the opening / closing mechanism that causes the first roller and the second roller to approach / separate from the feed roller, and the lock that presses the second roller against the outer peripheral surface of the feed roller. The biasing direction of the means can be completely different. Accordingly, it is not necessary to increase the biasing force (spring force) in order to maintain the opening / closing mechanism in the closed state, and as a result, the operation for switching the opening / closing mechanism can be performed lightly with a small force.

The label issuing device according to the present invention can increase the pressing contact force of the strip mount with respect to the outer peripheral surface of the feed roller by using the tension of the strip mount according to the configuration according to claims 1 to 3, and accordingly, the press roller (first roller, The urging force that presses the second roller) against the outer peripheral surface of the feed roller can be made weaker than in the conventional structure. Therefore, the opening / closing operation of the opening / closing mechanism that switches the approach and separation between the first roller and the second roller with respect to the feed roller can be lightly performed with a small force.
In addition, since the belt-like mount is wound around the outer peripheral surface of the feed roller by two rollers, the contact area between the feed roller and the belt-like mount can be increased, thereby pressing rollers (first roller, second roller) against the feed roller. ) There is no need to increase the pressing force. Therefore, the opening / closing operation of the opening / closing mechanism can be lightly performed with a small force.

  According to the configuration of claim 4, the switching direction of the opening / closing mechanism for causing the pressing roller (first roller, second roller) to approach / separate from the feed roller, and the pressing roller (second roller) to the outer periphery of the feed roller Since the urging direction of the locking means that presses against the surface can be made in completely different directions, there is no need to increase the urging force (spring force) in order to maintain the opening / closing mechanism in the closed state. The switching operation can be performed lightly with a small force. In addition, since it is not necessary to separately provide a lock member for maintaining the closed state of the opening / closing mechanism, the configuration can be simplified.

Hereinafter, an example of an embodiment of a label issuing apparatus according to the present invention will be described with reference to the drawings.
FIG. 1 shows an outline of a label issuing device provided with a sticking means. The label issuing device A includes a label supply unit A1, a printing unit A2, a peeling unit A3, a mount winding unit A4, etc. in a box-like case 1. In a box-shaped case 1 ′ attached to the side of the case 1, a sticking means A5 for sticking a label peeled and issued from the belt-like mount to the product W is arranged.

A label roll 2 ′ in which a label sheet 3 is attached to a long belt-like mount 2 so as to be peeled off at a predetermined interval and wound in a roll shape is set to be rotatable by a roll set 4. Has been.
The belt-like mount 2 of the label roll 2 'drawn out from the label supply unit A1 is guided to the printing unit A2, and the product name, price, and bar of the product W are printed by the thermal print head 5 and the platen member 6 in the printing unit A2. Product data such as a code is printed on the label paper 3 on the belt-like mount 2. After that, when the label roll passes through the peeling portion A3 disposed on the downstream side of the printing portion A2, the printed label paper, that is, the label 3 ′ is automatically peeled from the belt-like mount 2 to the label issuing port. The product is transferred and pasted on the upper surface of the product W conveyed on the belt conveyor B by the pasting means A5 disposed in the case 1 ′.
Further, the strip-shaped mount 2 from which the label 3 ′ (printed label paper) has been peeled is guided to the mount winding portion A 4 and is wound on the mount winding shaft 7.

  The feed means A6 that pulls out the strip 2 of the label roll 2 'set in the label supply unit A1 and introduces it into the printing unit A2 winds the strip 2 on the feed roller 8 and the outer peripheral surface of the feed roller 8. The feed roller 8 is supported by a mounting frame 10 installed and fixed in the case 1 and is driven to rotate by a motor (not shown). The first roller 9 and the second roller 9 ′ are composed of a first roller 9 and a second roller 9 ′. The two rollers 9 ′ act to wrap the belt-shaped mount 2 around the half circumference of the feed roller 8. The first roller 9 and the second roller 9 ′ are arranged so as to be able to switch between contact and separation with respect to the feed roller 8. The contact and separation are switched by the platen member 6 with respect to the thermal print head 5 constituting the printing portion A2. It is configured to be performed simultaneously by the opening / closing mechanism 13 that operates the contact / separation switching.

  The printing part A2 is composed of a thermal print head 5 and a platen member 6 arranged so as to face the thermal print head 5, and a strip of a label roll 2 'drawn out by driving rotation of the feed roller 8 of the feed means A6. Necessary product data is printed on the label paper 3 attached to the mount 2. The printing is performed by printing the data for one dot line supplied from the shift register by moving the belt-like mount 2 (label paper 3) by the feed roller 8 of the feed means A6 for each dot line. The feed roller 8 that pulls out and conveys the belt-like mount from the label roll is driven by a stepping motor. Further, the stepping motor is commonly used for the drive rotation of the mount winding shaft 7 of the mount winding portion A4.

  The thermal print head 5 of the printing unit A2 has a flat head shape and is supported by a fixing member in the case 1 (not shown). The illustrated thermal print head 5 is a flat type head in which a heater line is provided at a position several millimeters (for example, 3 mm) behind the end of the head (front end in the direction of transport of the belt-like mount). May be of the type provided at the end (near edge) of the thermal print head, and by using such a type of head, the blank print area of the label 3 'can be further reduced. .

  The platen member 6 disposed to face the thermal print head 5 is bent and inclined so that one side portion of the metal flat plate having a rectangular shape in plan view (front side in the transport direction of the belt-like mount 2) is bent upward. A chevron-shaped convex portion 11 is bent at the distal end, and the distal end side protruding forward from the convex portion 11 is inclined upward to form a peeling portion A3 in the same body. An elastic member 12 that elastically deforms when a load is applied to a position of the platen member 6 that faces the thermal print head 5, and a member that reduces the sliding resistance of the belt-like mount 2 on the upper surface of the elastic member 12. Etc. are stacked and detachably attached. The platen member 6 is attached to an opening / closing mechanism 13, and the approach / separation of the thermal print head 5 can be switched by operating the opening / closing mechanism 13. The distance from the center of the convex portion 11 to the peeling portion A3 is less than half (for example, 5 mm) as compared with the conventional structure (a structure in which a roller is used as a platen member).

  The convex portion 11 is linearly formed along the width direction of the platen member 6 at a position corresponding to the heater line 5 a of the thermal print head 5. By this convex portion 11, the label paper 3 on the belt-like mount 2 conveyed between the thermal print head 5 and the platen member 6 can be reliably pressed against the heater line of the thermal print head 5 with a small pressure. Make sure printing is possible. In addition, the shape of the convex part 11 is not limited to the form in which the apex appears on the line, but may be a trapezoid having a width along the transport direction of the belt-like mount 2.

  The peeling portion A3 is formed to protrude forward from the convex portion 11 formed by bending a flat plate and above the apex of the convex portion 11, and the belt-like mount 2 to which the printed label sheet is attached is the peeling portion. By folding back to the lower side of the platen member 6 in A3, the belt-like mount 2 and the label 3 ′ (printed label paper) are separated, the label 3 ′ is transferred to the sticking means side, and the belt-like mount 2 is taken up by the mount. Guided to the part A4 and wound on the mount winding shaft 7.

The elastic member 12 is a sponge-like member or a rubber member that is elastically deformed when a load is applied, and the label paper 3 affixed to the belt-like mount 2 is elastic against the heater line of the thermal print head 5. Press.
The elastic member 12 is a member that reduces the sliding resistance of the belt-like mount 2 on the upper surface of the elastic member 12 when the upper surface (the surface on which the belt-like mount 2 is slid and guided) becomes resistant to the sliding of the belt-like mount 2. Are laminated.
As a member for reducing sliding resistance, a plate-like member made of ultra high molecular weight polyethylene (UHMW) is used. The member is not limited to ultra high molecular weight polyethylene (UHMW), and may be a plate-like member made of ordinary high molecular weight polyethylene, or a material such as Teflon (registered trademark) or silicon.

  The opening / closing mechanism 13 that supports the platen member 6 includes front and rear swing arms 14a and 14b formed in a substantially flat L shape with a metal flat plate, and both arms on the rear half of the front and rear swing arms 14a and 14b. The frame 14 is integrally formed with a connecting portion 14c that is connected at intervals, and a platen member mounting base 15 that is installed between the front half portions of the front and rear swing arms 14a and 14b. Is pivotally supported by a fixed member in the case 1 by a pin 16 so as to be swingable up and down.

The first roller 9 and the second roller 9 ′ of the feed means A 6 are attached to the opening / closing mechanism 13 with a shaft-shaped swinging member 17 on the inner side of the rear portion of the base frame 14 constituting the opening / closing mechanism 13. The first roller 9 and the second roller 9 ′ are rotatable on the swing member 17, and the feed roller 8 is inserted between the rollers 9 and 9 ′ so that the feed roller 8 is fitted between them. Is pivotally supported.
The first roller 9 and the second roller 9 ′ act so as to wind the belt-like mount 2 wound around the outer peripheral surface of the feed roller 8 over about a half or more of the outer peripheral surface of the feed roller.
Further, when the first roller 9 moves in the direction away from the feed roller 8 due to the tension of the belt-like mount 2 passed between the first roller 9 and the second roller 9 ′ and the feed roller 8, Two rollers 9 ′ are supported by the shaft 18 so as to swing in a direction in which they are pressed against the outer peripheral surface of the feed roller 8.

  Further, a coil spring (biasing means) 19 is elastically mounted on the front and rear swing arms 14a and 14b of the opening / closing mechanism 13 and the front and rear walls of the swing member 17 corresponding to the front and rear swing arms 14a and 14b. The grooves 20 and 21 are notched and a coil spring (biasing means) 19 is elastically mounted between the grooves 20 and 21. The coil spring 19 urges the second roller 9 ′ supported by the swing member 17 in a direction in which the second roller 9 ′ is pressed against the outer peripheral surface of the feed roller 8.

Further, on the front and rear swing arms 14a and 14b, the support shaft of the second roller 9 'attached to the swing member 17 is below the axis of the feed roller 8 and close to the outer peripheral surface of the feed roller. A guide arc hole 22 that guides in the direction to be cut is formed.
Further, an operating piece 23 that swings the swinging member 17 up and down about the shaft 18 is bent at a substantially right angle at the end of the upper side of the swinging member 17, and the upper surface of the operating piece 23 is the base. By contacting the connecting portion 14 c of the frame 14, the opening / closing mechanism 13 can be switched to the open state via the swing member 17.
The mounting frame 10 that pivotally supports the feed roller 8 is provided with a stopper rod 24 that is positioned upstream of the feed roller 8, thereby rotating the open / close mechanism 13 in the closing direction. The rotation (closing movement) is restricted at a predetermined position (the positional relationship between the thermal print head 5 and the convex portion of the platen member). The front and rear swing arms 14a and 14b of the base frame 14 of the opening / closing mechanism 13 are notched with engagement recesses 25 that are fitted and engaged with the stopper rods 24.

Next, the operation of winding and releasing the belt-like mount 2 around the feed roller 8 in the feed means A6 will be described with reference to FIG.
First, as shown in FIG. 1, the strip-shaped mount 2 that has come out from the label roll 2 ′ passes through the printing portion A 2 and the peeling portion A 3, and is between the feed roller 8, the first roller 9, and the second roller 9 ′ of the feed means A 6. The belt-like mount 2 is drawn out and conveyed by the rotation of the feed roll 8 and the mount take-up shaft 7 of the mount take-up portion A4. When the label is printed, the opening / closing mechanism 13 is closed, and the first roller 9 and the second roller 9 ′ that wrap the belt-like mount 2 around the outer peripheral surface of the feed roller 8 include the swing member 17 and a coil spring (biasing force). (Means) 19 maintains the closed state shown in FIG. 5A when the second roller 9 ′ hits the feed roller 8 with respect to the substantially vertical direction, which is the opening direction of the opening / closing mechanism 13 in the second roller 9 ′.
That is, when the opening / closing mechanism 13 is closed and the tension of the belt-like mount 2 is applied to the first roller 9, the swing member 17 is rotated clockwise about the shaft 18 by the tension, and the first roller 9 is The second roller 9 ′ moves away from the feed roller 8 and moves in a direction in which the second roller 9 ′ is pressed against the outer peripheral surface of the feed roller 8. Further, the elastic force of a coil spring (biasing means) 19 interposed between the opening / closing mechanism 13 and the swing member 17 acts on this swing, and the belt-like mount 2 is half-circulated on the outer peripheral surface of the feed roller 8. It is wound up. Thereby, the contact friction between the feed roller 8 and the belt-like mount 2 is increased, and the belt-like mount 2 can be stably conveyed.

  When releasing the set state of the belt-like mount 2, as shown in FIG. 5B, a finger is put on the lower surface of the operation piece 23 of the swing member 17 and lifted in the vertical direction about the shaft 18. The lifting of the swing member 17 compresses a coil spring (biasing means) 19 that is elastically mounted between the opening / closing mechanism 13 and the swing member 17. Due to the swing of the swing member 17, the second roller 9 ′ moves in a direction away from the outer peripheral surface of the feed roller 8 along the guide arc hole 22 formed in the front and rear swing arms 14 a and 14 b of the opening / closing mechanism 13. Is done.

  When the swinging member 17 continues to be lifted, the operation piece 23 comes into contact with the connecting portion 14c of the opening / closing mechanism 13, and when the swinging member 17 is further lifted, the opening / closing mechanism 13 is centered on the pin 16 by the force. The platen member 6 side opposite to the side on which the swing member 17 is engaged is rotated in a direction away from the thermal print head 5. When the lifting of the swing member 17 is stopped after the opening / closing mechanism 13 is opened, the swing member 17 is moved downward by the elastic force of the coil spring (biasing means) 19 as shown in FIG. The operation piece 23 is swung away from the connecting portion 14c, and the first roller 9 and the second roller 9 ′ can also release the winding of the belt-like mount 2 around the feed roller 8, and the belt-like mounting 2 can be easily removed. It becomes a state.

In the embodiment described above, the first roller 9 and the second roller 9 ′ for winding the belt-like mount 2 around the outer peripheral surface of the feed roller 8 are attached to the swing member 17, but only at least one of the rollers (second roller) is swung. The other roller (first roller) may be attached to the opening / closing mechanism 13 and attached to the moving member. The configuration will be briefly described below with reference to FIG. In addition, the same member as the member shown by the previous example attaches | subjects the same code | symbol, and abbreviate | omits description.
The configuration is such that the first roller 9 is rotatably supported horizontally across the front and rear swing arms 14a and 14b of the frame 14 constituting the opening / closing mechanism 13 so as to be rotatable. The second roller 9 ′ arranged further downstream is attached to a swinging member 26 that is pivotally supported by a shaft 18 so as to be swingable with respect to the opening / closing mechanism 13.

The rocking member 26 has a shape in which a portion of the rocking member 17 supporting the first roller 9 in the previous embodiment is cut, and similar to the previous embodiment, the opening / closing mechanism 13 and the rocking member 26 are separated. A coil spring (biasing means) 19 mounted over the second roller 9 ′ is urged in a direction in which the second roller 9 ′ is pressed against the outer peripheral surface of the feed roller 8, and the shaft of the second roller 9 ′ is It is fitted in a guide arc hole 22 established in the front and rear swing arms 14a and 14b.
The direction of the guide arc hole 22 that guides the second roller 9 ′ in the direction in which the second roller 9 ′ is pressed against the feed roller 8 is an opening / closing mechanism that causes the second roller 9 ′ to approach / separate from the outer peripheral surface of the feed roller 8. The lock means 27 is formed in a direction different from 13 switching directions (opening and closing directions) (a direction close to orthogonal). That is, the switching direction of the opening / closing mechanism 13 is a substantially vertical direction, while the direction in which the second roller 9 ′ is pressed and urged against the feed roller 8 is a direction obliquely intersecting the vertical direction.

  With the above configuration, when the belt-like mount 2 is set and the opening / closing mechanism 13 is closed, as shown in FIG. 6A, the swinging member 26 pivotally supported by the opening / closing mechanism 13 is a coil spring (biasing means). The second roller 9 ′ is moved and urged in a direction to press and contact the outer peripheral surface of the feed roller 8 by the elastic force of 19 and the guide arc hole 22. Is wound around the outer peripheral surface of the feed roller 8 more than half a circle.

  When the closed opening / closing mechanism 13 is opened, as shown in FIG. 6B, when the finger is placed on the operation piece 27 of the swinging member 26 and lifted upward, the operation piece is the same as in the previous embodiment. 27 abuts on the connecting portion 14c of the opening / closing mechanism 13, and the opening / closing mechanism 13 can be rotated in the opening direction. When the swinging member 26 is lifted upward against the spring force of the coil spring (biasing means) 19 and the operation piece 27 comes into contact with the connecting portion 14c of the opening / closing mechanism 13, the second roller 9 ' Since the pressing contact of the strip-shaped mount 2 is released from the outer peripheral surface of the feed roller 8, the strip-shaped mount 2 can be removed at the feed means A6.

  In the second embodiment described above, when the second roller 9 ′ is moved away from the outer peripheral surface of the feed roller 8, the first roller 9 is not interlocked with the movement of the second roller 9 ′ as in the first embodiment. The first roller 9 does not have to be separated from the feed roller 8 so that the first roller 9 can be disposed at a position close to the feed roller 8, and the belt-like mount 2 is placed on the feed roller 8. It is possible to wind more around the outer peripheral surface.
