Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a secret label sticking device for sticking a hot-melt type secret label to a government postcard or a sheet of private postcards, and particularly to storing a postcard before sticking. The postcard is delivered from the postcard storage section while being corrected to a predetermined posture.

[0002]

2. Description of the Related Art In recent years, a secret label has been attached to a portion where confidential information is written such as notification of insurance amount, tax, etc., the information is hidden in the middle of mailing, and after the authorized recipient receives it. A postcard has been developed in which the secret label can be easily peeled off so that the information can be viewed. There are two types of secret labels: an adhesive type that is attached by the adhesive force of the adhesive layer formed on the back side, and a hot melt type that applies an adhesive that melts when heated to the back side and heat-presses it. Since it must be peeled off from the release paper and attached to the postcard, it is not suitable for mechanical processing. In addition, the adhesive type causes various problems such as a problem of discarding the release paper, an increase in the cost of the release paper, and a problem that the number of labels decreases with the same diameter when wound on a coil. For this reason, hot-melt type secret labels have been attracting attention in order to perform a large number of processes in a short time. A conventional label sticking device for sticking this hot-melt type secret label to a postcard is disclosed in, for example, Japanese Patent Laid-Open No. 1-294419, in which a coil around which a series of secret labels are wound has a horizontal axis. The continuous label that is detachable to the size of the official postcard is transported in the horizontal direction, the secret label unwound from the coil is cut into a predetermined length with a cutter, and the secret label is fed during the transfer. In general, a structure in which a secret label is attached to a postcard by superposing it at a position and passing it between heating and pressurizing devices has been adopted.

[0003]

The above-mentioned conventional label sticking apparatus has a structure in which postcards, which are pasted materials, are sent in the form of continuous paper, so that a label is stuck to a sheet such as a postcard manufactured by a government. It cannot be processed. Further, when the postcards in a sheet state are piled up and stored in a storage unit, and the postcards are fed one by one by rotation of a feeding roll provided at an exit portion of the storage unit, when the postcards are put into the storage unit. In addition, it is necessary to accurately align the top, bottom, left and right of the postcard. If the postcards are not aligned properly, the position of the postcard delivered by the delivery roll is displaced, and the label cannot be attached at a predetermined position. If a device for correcting the position of the postcard is additionally provided during transportation, not only the structure becomes complicated but also the entire device becomes large. Therefore, there has been a demand for the development of a secret label sticking device capable of sticking a label at a predetermined position even when the postcards are not aligned to the upper and lower sides and right and left when the postcard is put into the storage portion, and the size can be reduced. Further, when the postcards are stored in the storage section, it is difficult to keep the contact pressure between the first postcard and the feeding roll properly, especially when the postcards are stored upright, and the contact pressure is too strong. The postcard may be damaged, or the contact pressure may be too weak to delay the feeding operation.

[0004]

SUMMARY OF THE INVENTION The present invention has been proposed in view of the above circumstances, and a first postcard storage section for storing sheet-like postcards to be pasted together is stored, and a postcard to which the pasting is performed is stored. A second postcard storage section, a transport mechanism disposed in the middle of a postcard transport path formed between the exit of the first postcard storage section and the entrance of the second postcard storage section, and a transport mechanism for transporting the postcard; A postcard in the first postcard storage section is provided with a heating and pressurizing mechanism arranged on the way and a label sending-out mechanism for superposing a label on the postcard in the middle of the transport path, and by rotation of the delivery roll arranged at the outlet of the first postcard storage section. In the secret label sticking apparatus for sticking the label to the postcard by feeding the postcard from the earliest one to the feeding path, superposing the postcard and the label in the middle of the feeding, and passing the heat and pressure mechanism in this state. Postcards sent from the postcard storage section pass A reference surface with which one edge of the postcard comes into contact is formed on one side of the entrance portion of the conveyance path, and the axis of the delivery roll provided at the exit of the first postcard storage portion is located at the end portion far from the reference surface. Is installed in an inclined state in which it is slightly tilted in the transport direction.

[0005]

When the leading postcard in the first postcard storage portion comes into contact with the delivery roll, the postcard receives a force that is fed laterally, that is, in the transport direction of the transport path due to the frictional force with the peripheral surface of the rotating roll. , It is pushed down to the reference plane of the conveying path by receiving the force in the diagonal direction. Therefore, when the postcard is sent to the top with the edge floating from the bottom surface of the first postcard storage section, the postcard is pressed against the end on the transport path side, and this post reaches the reference plane first. When this postcard is pushed down and moved by the rotation of the feeding roll, the press contact position of the feeding roll gradually moves with this movement, so push down while sending the floating part with this movement,
By the time the delivery roll comes into contact with the upstream end of the postcard, the postcard is corrected to a normal posture in which almost the entire length of the lower edge is in contact with the reference surface. Therefore, the postcard delivered by the delivery roll is started to be conveyed in a regular posture at a predetermined height with its end edge in contact with the reference surface. When this postcard is conveyed along the conveyance path by the operation of the conveyance mechanism, the label feeding mechanism overlaps the label during the conveyance, and when it passes through the heating and pressing mechanism in this superposed state, the label is attached to the postcard. To be done.

[0006]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of the secret label sticking device 1, and FIG. 2 is a plan view thereof. A secret label sticking device 1 shown in this drawing has a coil mounting portion 3 for mounting a coil wound with a series of secret labels in a state in which the coil is wound in the axial direction vertically on the front side of the upper surface of the main body 2 in the left-right center.
In the horizontal direction (front-back direction) in a state where a postcard before sticking is placed on one side (right side in the drawing) of the coil mounting portion 3
To form a second postcard storage section 5 that stores the first postcard storage section 4 that is stored on top of the other side (left side in the drawing) in a horizontal direction (front-rear direction) with the postcard that has been processed being set up on the other side. , First
A postcard transport path 6 is formed between the front end of the postcard storage unit 4 and the front end of the second postcard storage unit 5, and the postcards in the storage unit 4 are fed to the front end of the first postcard storage unit 4 one by one. A guide that guides the postcard to the second postcard storage section 5 at the tip of the second postcard storage section 5, and a transport mechanism that conveys the postcard sent out by the feeding mechanism to the postcard transfer path 6. Mechanisms are provided respectively, and between the coil mounting portion 3 and the postcard conveying path 6, the secret label unwound from the coil 7 is cut into a predetermined length and sent out to the overlapping position in the middle of the postcard conveying path 6. A mechanism is provided, and a heating and pressurizing mechanism is provided in the postcard conveying path 6 on the downstream side of the superposition section.

In FIG. 1, reference numeral 8 is a cover for covering the coil placed on the table, and a portion for closing the right side surface of the cover 8 functions as a guide plate 9 of the first postcard storage section 4,
The part that closes the left side surface functions as the guide plate 10 of the second postcard storage part 5.

Further, as shown in FIG. 4, a secret label 11 stuck by the secret label sticking apparatus 1 of the present invention has a concealing layer 13, a peeling layer 14 and a hot layer on the back surface of a substrate 12 such as paper or a synthetic resin sheet. The hot melt layer 15 is formed by forming the melt layer 15 and is adhered to the postcard 16 by being melted by heat, and the concealment layer 13 surely prevents the items described in the postcard 16 from being visually recognized. When the authorized recipient who receives the postcard 16 peels the secret label 11 from the peeling layer 14, the written matter can be read through the transparent hot melt layer 15. It should be noted that on the surface of the secret label 11, eye marks 17 for position detection are printed at predetermined positions at intervals of each sheet, or holes 18 are formed at predetermined positions.
Has been established.

On the other hand, the postcard 16 as the adherend is a postcard made by the government or a private postcard cut to a predetermined size, and each of them is a sheet of paper.

For convenience of explanation, first, a mechanism for cutting and sending a series of secret labels 11 one by one will be described. A table 19 for mounting and rotating the coil 7 is provided on the coil mounting portion 3 formed on the upper surface of the main body 2, and the table 19 is rotated by a motor inside the main body 2 so that the coil 7 can be appropriately unwound. . Then, the released series of secret labels 11 ... Is guided to the label delivery mechanism by being guided by the tension roll 20 and the guide roll 21 which are movable in the arrow direction in FIG. The tension roll 20 not only keeps the tension of the released series of labels almost constant, but when a large tension acts and moves to a predetermined position, the tension roll 20 supports the tension roll 20 and interlocks with the swinging arm rod 22. A switch (not shown) to be operated is turned on to start the motor of the table 19 so that the coil 7
Solve

The table 19 is rotatable in a normal state, and a label feeding mechanism, which will be described later, has a series of labels 11 ...
When you pull, the table 19 rotates and the coil 7 unravels,
Tension roll 2 when unwound length is sufficient
The mechanical brake is mechanically operated by a brake that operates in conjunction with the arm rod 22 of 0, or the electromagnetic brake is activated by a signal from a switch that is turned on / off at the position of the arm rod 22 to stop the rotation of the table 19. You may comprise.

In any of the configurations, when the size of the coil 7 to be placed (width of the secret label 11) is input by operating the operation section 23 of the operation panel, the table 19 moves up and down according to the size of the coil 7. Move. Further, by operating the operation unit 23 ... Of the operation panel, the cutting length of the label 11, that is, the left and right width in the state of being attached to the postcard 16, the attaching height of the label 11, the processing speed, etc. are set in the control device. This setting allows the guide 24 of the label feeding mechanism to move to a predetermined height and automatically perform necessary adjustments. For example, when the size of the label 11 is set, the table 19 and the lower guide portion of the guide 24 move up and down to adjust the position of the lower edge of the label 11, and the upper guide portion of the guide 24 moves up and down. It moves to a position corresponding to the upper edge of the label 11. Further, the heating temperature of the heating mechanism can be set to a temperature suitable for the conditions such as the characteristics of the hot melt layer 15 of the label 11.

The label feeding mechanism is arranged along a label traveling path formed in a direction intersecting the postcard conveying path 6 at an angle, and when described in order from the entrance side, two plate materials are opposed to each other. A label guide 24 and a label 11 for guiding at a set height through a series of labels 11 ...
A label position detector 25 for detecting the position of the label 11 by detecting the eye mark 17 or the hole 18 printed on the label, a pair of label feed rolls 26, 26, a cutter 27, and the cutter 2.
It is composed of a pair of label feeding belts 28, 28 and the like which feeds one label 11 cut by 7 between them. The label position detector 25, the drive motors for the label feed rolls 26, 26, the drive solenoid for the cutter 27, the drive motors for the label feed belts 28, 28, etc.
It is connected to a control device such as a microcomputer, and operates by a signal from this control device.

When the label position detector 25 detects the position of the label 11 by detecting the eye mark 17, the label feeding rolls 26, 26 rotating by a signal from the control unit feed a series of labels 11 ... Label 11,
The boundary of 11 (that is, the cutting position) is aligned with the cutter 27, and the feeding of the series of labels 11 ... Is temporarily stopped at this position. Then, the cutter 27 is actuated by a signal from the control device to cut the leading portion of the series of labels 11 ... To a predetermined length and separate it into one secret label 11. When the cutting is performed in this manner, the leading end portion of the separated label 11 is sandwiched between the label feeding belts 28, 28, so that the label feeding belts 28, 28 receive the label 11 by the signal from the control device. It is sent to the overlapping section of the postcard transport path 6. Since the label 11 must be superposed on the postcard 16 at a predetermined position, the label feed belts 28 and 28 operate in synchronization with the postcard feed mechanism described later under the control of the controller.

Next, the first postcard storage section 4 for stocking postcards 16 ... Before attaching the label 11 will be described. First
In the postcard storage unit 4, the upper surface of the main body 2 functions as a bottom surface on which the postcards 16 are placed, and the guide plate 9 on the right side of the cover 8 regulates the position on the left side of the postcards 16 ... The part 29 regulates the right side position of the postcards 16 ... And the postcard pressing mechanism sequentially sends the postcards 16 ...
The first postcard storage unit 4 shown in this embodiment can store about 2000 postcards 16 ...

In the postcard pressing mechanism shown in the drawings, the slit hole 3 is formed substantially at the center of the bottom surface of the first postcard storage portion 4 along the longitudinal direction.
0 is opened, the pressing portion 32 is fixed to the upper end of the leg portion 31 passed through the slit hole 30, and the pressing portion 32 is moved forward to press the postcard 16 ... The pressing portion 32
Any mechanism may be used to drive the, but for example, an endless belt is stretched inside the main body 2 in the longitudinal direction of the first postcard storage portion 4, and the lower end of the leg portion 31 is connected to this belt to connect the belt. The pressing portion 32 may be configured to move back and forth by being rotated by a drive motor, or a ball screw may be provided in the front and rear direction and the lower end of the leg portion 31 may be connected to a ball nut to move back and forth. You may comprise.

Further, in order to properly adjust the pressure for pressing the postcards 16 ... In this embodiment, a detector which is actuated by the movement of the feeding roll, which will be described later, is provided, and the drive motor is driven based on a signal from the detector. The on / off is controlled to adjust the pressing force of the postcard 16 ... Therefore, the frontmost postcard 16 of the postcards 16 ... Stored in the first postcard storage section 4 is always pressed forward by an appropriate force, and is delivered to the one-postcard delivery path 6 by the delivery mechanism.

The feeding mechanism includes a feeding roll 33 provided at the tip of the first postcard storage unit 4, that is, at the outlet, and a pair of overlapping prevention rolls 34a, 34b provided on the downstream side of the feeding roll 33.
Consists of. Further, the bottom surface of the first postcard storage section 4 is extended from the outlet to the entrance portion of the postcard transport path 6, and the postcard transport path 6 is provided.
One side of the entrance portion (the bottom surface of the transport path 6 in this embodiment) is set as the reference surface 35, and one end edge (the lower end edge in this embodiment) of the postcard 16 contacts the reference surface 35. Constitute. Then, the delivery roll 33 rotates (normally rotates) in the feeding direction of the postcard 16, and the leading postcard 1 in the first postcard storage unit 4
The postcard 16 is pressed against the reference plane 6 and the lower end edge is the reference plane 3
The configuration is adopted in which it is sent out while being corrected to an appropriate posture in which it contacts 5. In this embodiment, the postcard 16 is conveyed in an upright state, and the bottom surface of the conveyance path 6 is set as a reference for the height of the postcard 16, so the bottom surface of the conveyance path 6 is used as the reference surface 35.
The reference surface 35 is not limited to this, and for example,
When the postcard 16 is conveyed in a horizontal state, either the left or right side wall surface of the conveyance path 6 may be set as the reference surface 35.

In this embodiment, as shown in FIG. 6, a plate-shaped support member 36 extending in the direction of the transport path 6 is attached to the outlet of the first postcard storage section 4 by a shaft 37. A rotary shaft 33 'of the pay-out roll 33 is attached to the downstream side of 37 in the transport direction, and the rotary shaft 33' is inclined so that its end farther from the reference surface 35, that is, the upper end, is slightly tilted in the transport direction. Install in the state (for example, about 5 degrees tilted). The delivery roll 33 is disposed not at the center of the exit portion of the first postcard storage unit 4 but at the end portion near the transport path 6 side.
6 so as to be in contact with the end of the delivery side. Therefore, the shaft 37 of the support member 36 is located on the upstream side of the transport path 6 with respect to the rotary shaft 33 '.

Further, the support member 36 is provided with a working arm 38 which extends on the opposite side of the shaft 37 with the rotary shaft 33 'interposed therebetween.
A detector 39 such as a photosensor that operates depending on the position of the tip acting portion 38 'of the working arm 38 is provided in a fixed state on the main body 2 side, and a spring 40 is connected to a portion extending on the side opposite to the working arm 38. Then, the feeding roll 33 is moved to the first postcard storage unit 4
Of the male screw rod 41 that is urged toward the outlet side of the
The tip of the can contact the side edge of the extended portion. Therefore, the support member 36 can be swung in the horizontal direction about the shaft 37, and the swinging of the support member 36 causes the feeding roll 33 to intersect the transport path 6, in other words, the transport path 6.
On the other hand, it moves back and forth, and normally moves forward due to the biasing force of the spring 40, and when it advances the most, the extended portion of the support member 36 comes into contact with the male screw rod 41 and stops. Therefore, if the screwing length of the male screw rod 41 with respect to the female screw portion 42 on the main body 2 side is adjusted, the most advanced position of the feeding roll 33 can be finely adjusted.

When the feeding roll 33 moves back and forth due to the swinging of the support member 36, the action portion 38 'of the working arm 38 moves while being amplified more than the amount of forward and backward movement of the feeding roll 33.
That is, the action portion 38 'of the action arm 38 moves largely in proportion to the ratio of the length from the shaft 37 to the rotating shaft 33' and the length from the shaft 37 to the action portion 38 '. Therefore, even if the amount of movement of the pay-out roll 33 is extremely small, that is, the thickness of one postcard, the amount of movement of the action portion 38 'is expanded to several mm, and therefore the action portion 38' is operated. When the detector 39 is provided in a fixed state on the main body 2 side, the detector 39 can electrically detect the first state in which the feeding roll 33 has advanced and the second state in which it has retracted. The detector 39 is electrically connected to a control device that controls the drive motor of the pressing mechanism.

Therefore, the pressing mechanism can repeatedly operate and stop based on the signal from the detector 39 to press the postcards 16 ... In the first postcard storage section 4 to the outlet side with an appropriate pressure. That is, if the pushing force of the postcards 16 ... In the first postcard storage unit 4 is insufficient and the feeding roll 33 has advanced to the first state, the signal from the detector 39 that has detected this first state is returned. The drive motor is driven, which causes the first
The postcards 16 ... in the postcard storage section 4 are provided on the outlet side (feeding roll 33
Side). This pushing force causes the postcards 16 to move forward, and the frontmost postcard 16 slightly retracts the feeding roll 33 to increase the pushing force to a proper pressure, which is amplified and moved by the action portion 38 'of the detector. 39 detects the second state and sends a signal to the control device, which causes the control device to stop the drive motor and stop pressing in this state.
Therefore, the first postcard 16 is pressed against the delivery roll 33 with a pressure that provides a sufficient frictional force.

As described above, since the upper end of the feeding roll 33 is slightly inclined in the conveying direction, and the detector 39 detects the movement when it moves back and forth with respect to the conveying path 6, the pressing mechanism is controlled. When the leading postcard 16 in the first postcard storage unit 4 contacts the delivery roll 33, the postcard 16 is transported laterally, that is, in the transport path 6 by a frictional force with the peripheral surface of the rotating roll 33. In addition to receiving the force sent in the direction, the reference surface 3 of the transport path 6 receives the downward force.
Pushed down to 5. For example, as shown in FIG. 7, the postcard 16 with its lower edge floating from the bottom surface of the first postcard storage unit 4
Is sent to the earliest, the postcard 16 is delivered to the delivery roll 3
3 is pressed against the end on the side of the transport path 6 and this end is first pushed down to the reference surface 35 (FIG. 7 (A)). When the postcard 16 is moved to the left side in the drawing by the rotation of the delivery roll 33, the press contact position of the delivery roll 33 is gradually moved to the right side of the postcard 16 with this movement (FIG. 7 (B)).
With this movement, the floating part is fed and pushed down, and as shown in FIG. 7C, when the delivery roll 33 comes into contact with the upstream end of the postcard 16, the postcard 16 has almost the entire length of the lower end edge. Is corrected to a normal posture in which the reference surface 35 abuts. Therefore, as shown in FIG. 7D, the postcard 16 delivered by the delivery roll 33 is started to be conveyed in a regular posture at a predetermined height with the lower end edge thereof in contact with the reference surface 35 (FIG. 7). (D)).

When the delivery roll 33 sends out the first postcard 16 in the first postcard storage section 4 in this manner, the thickness of the laminated postcard 16 is reduced by the thickness of the sent postcard 16. As a result, the pressing pressure of the postcard 16 against the delivery roll 33 is reduced. Therefore, the feeding roll 33 is
It moves forward by about the thickness of one sent postcard and contacts the surface of the next postcard. Feeding roll 3 in this state
If 3 is in pressure contact with the postcard 16 with a sufficient pressure, the postcard 16 is sent out by the same action as described above. Then, when the feeding roll 33 advances until the contact pressure of the postcard 16 with respect to the feeding roll 33 is insufficient due to repeated feeding, the action portion 38 ′ acts on the detector 39 due to the swinging of the support member 36, and the detector 39 The drive motor of the pressing mechanism operates based on the signal. Therefore, the postcards 16 in the first postcard storage unit 4 ...
Is pressed against the pay-out roll 33 with a sufficient pressure.

When a sufficient pressure acts on the feeding roll 33, the feeding roll 33 retracts against the bias of the spring 40, the supporting member 36 swings in the opposite direction, and the acting portion 38 'moves largely. To do. Therefore, the control device stops the drive motor of the pressing mechanism in response to a signal from the detector 39 that detects this movement.

In this way, when the contact pressure of the postcard 16 in contact with the delivery roll 33 is properly adjusted, the posture of the frontmost postcard 16 is properly corrected by the rotation of the delivery roll 33 as described above. It is sent to the transport path 6.

Since the feeding roll 33 is provided at a relatively low position so as to come into contact with the lower portion of the postcard 16, it is prevented that the postcard 16 is pushed down too much or that the postcard 16 buckles or bends. be able to.

Next, the overlap prevention rolls 34a and 34b will be described. These overlapping prevention rolls 34a, 34b
Is a normal roll by rotating one roll 34a aligned with the feeding roll 33 in the transport direction of the postcard 16, and the other roll 34b provided on the opposite side across the transport roll 6 from the normal roll 34a is the postcard 16 The roll is a reversing roll that rotates in a direction opposite to the conveying direction, and the distance between the outer peripheral surfaces of both rolls 34a and 34b is set to a distance that allows only one postcard 16 to pass.
This interval needs to be adjusted to the thickness of the postcard 16 to be used. Therefore, in this embodiment, the shaft of the reversing roll 34b is fixed to the main body 2 side, and the shaft of the forward rotation roll 34a is set to the transport path 6. It is constructed so that it can move in the intersecting direction. In this embodiment, the forward roll 34a is movable and the reverse roll 34b is fixed, but the forward roll 34a may be fixed and the reverse roll 34b may be movable.

Specifically, as shown in FIG. 6, a horizontally elongated adjusting lever 44 is pivotally mounted on a support shaft 43 at one end thereof.
Is provided, and the forward rotation roll 34a is provided in the middle of the adjustment lever 44.
Of the adjustment lever 44, a fixing screw 45 is provided on the free end side of the adjusting lever 44 as a clamping means, the side surface on the free end side is a movable holding portion 46, and a fixed holding portion 47 is provided at a position facing the movable holding portion 46. Is fixed to the main body 2 side.

When the fixing screw 45 is loosened, the adjusting lever 44 can be swung about the support shaft 43. This swing increases or decreases the distance between the forward rotation roll 34a and the reversal roll 34b, and at the same time, makes it movable. Holding part 46 and fixed holding part 4
The interval with 7 also increases or decreases. The distance between the support shaft 43 and the normal rotation roll 34a and the support shaft 4 are increased or decreased.
It is almost proportional to the ratio of the distance from 3 to the movable holding portion 46.
Therefore, the number of postcards 16 ... Corresponding to this ratio are sandwiched between the movable holding portion 46 and the fixed holding portion 47, and the fixing screw 45.
When the adjustment lever 44 is fixed by tightening the
The distance between 4a and 34b can be set as the optimum distance for the thickness of the postcard.

If the interval between the overlap preventing rolls 34a and 34b can be set by sandwiching a plurality of postcards 16 ... In this way, it goes without saying that the optimum interval setting work is easy and the sticking process is performed. If the postcard 16 is provided, a measuring instrument, a tool for adjustment, a gauge, etc. are unnecessary, and it is not affected by the habit of the operator or the measurement error.

In order to make the force for holding a predetermined number of postcards 16 by the movable holding portion 46 and the fixed holding portion 47 constant, the adjusting lever 44 is attached to the spring 4 in this embodiment.
8 is connected, and the movable holding portion 46 is biased toward the fixed holding portion 47 side by the biasing of the spring 48. Further, in the present embodiment, the postcard 1 is provided between the movable pinching part 46 and the fixed pinching part 47.
The intervals between the support shaft 43, the forward rotation roll 34a, and the movable gripping portion 46 are set so that the interval between the rolls 34a and 34b can be set to an optimal gap when 10 sheets of 6 ... Are stacked and sandwiched.
After setting the above interval, postcard 16
... is removed and stocked in the first postcard storage unit 4.

As described above, the overlap prevention roll 34
When the interval of a and 34b is set, when one postcard 16 is delivered by the rotation of the delivery roll 33, the postcard 16 is conveyed through between the rolls 34a and 34b, and the delivery roll 33 rotates. When the postcards 16 are delivered by overlapping with each other, the postcards 16 in contact with the delivery roll 33 and the forward rotation roll 34a, that is, the first postcard storage unit 4
The first postcard 16 of the postcard 16 is pushed out as it is in the transport direction and passes between the forward and reverse rolls 34a and 34b, but the postcard 16 that is fed out overlapping this postcard 16 is pushed back when it comes into contact with the reverse roll 34b. , Both rolls 34a,
You cannot enter between 34b. Therefore, both rolls 34
The postcard 16 passing between a and 34b is regulated only by the leading postcard 16, and the postcard 1 and the second and subsequent sheets that are fed out in an overlapping manner.
6 continues to be pushed back until the leading postcard 16 passes, and when the leading postcard 16 passes, it is sent out in the conveyance direction by the rotation of the feeding roll 33 and the forward rotation roll 34a and passes between both rolls 34a and 34b. It should be noted that the feeding roll 33 is intermittently rotated, the rotation is stopped when one postcard 16 is fed from the first postcard storage unit 4, and the rotation is stopped while the reversing roll 34b is blocking the passage of the second postcard 16. The delivery roll 33 may be configured not to apply the delivery force even when the delivery roll 33 contacts the second postcard 16. In this way, the tip portion of the second postcard 16 is not strongly pressed by the reversing roll 34b,
It is possible to prevent damage to the tip portion of the postcard 16.

The postcards 16 sent out in the state of being separated one by one as described above are individually conveyed in a standing state to the overlapping position by the action of the conveying mechanism provided in the conveying path 6. The transport mechanism according to the present exemplary embodiment includes the overlapping prevention roll 34.

[0046]

As described above, according to the present invention, even if the adherend is a postcard for a sheet of paper, the label can be adhered efficiently, and from the first postcard storage section. A reference surface with which one edge of the postcard comes into contact is formed on one side of the entrance portion of the transport path through which the postcard sent out passes, and the axis of the delivery roll provided at the outlet of the first postcard storage unit is Since the end of the postcard is installed in an inclined state that is slightly tilted in the transport direction, even if the top, bottom, left, and right edges of the postcard are slightly uneven when the postcards are stacked in the first postcard storage part, When the delivery roll delivers the postcard, the end edge of the postcard is corrected to an appropriate posture so as to contact the reference surface of the transport path. Therefore, the postcard can be conveyed in a predetermined posture without separately providing a postcard position adjusting mechanism in the conveying path thereafter, and thus a label can be attached at a predetermined position of the postcard. Further, since it is not necessary to provide a postcard position adjusting mechanism in the middle of the conveying path, the entire apparatus can be downsized. Further, a postcard feeding mechanism that sends the postcard in the first postcard storage section to the outlet side by driving the drive source is provided, and the feeding roll can be moved in the direction intersecting the transport path, and is biased to the transport path side by the spring. A delivery roll is provided with a detector for detecting a first state in which the delivery roll approaches the transport path side and a second state in which the delivery roll is retracted, and the detector is electrically connected to the drive source of the postcard feeding mechanism through a control device. When the drive source of the postcard feeding mechanism is operated in the first state in which the postcard approaches the transport path, the contact pressure between the frontmost postcard and the delivery roll can be appropriately maintained. Therefore, even when the postcard is stored in the storage section in an upright state, the contact pressure between the frontmost postcard and the feeding roll can be appropriately maintained, which damages the postcard or the feeding operation. It is possible to eliminate inconveniences such as delay.
