Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a label affixing device for affixing a label to a product, in particular, a label is affixed to a mount at predetermined intervals, and the label is peeled off from the mount and automatically affixed to a predetermined position of a moving product. It relates to an optimal labeling device.
[0002]
[Prior art]
Conventionally, this type of label sticking device is roughly classified into a sticking method, (1) an air jet sticking method, and (2) a pressure sticking sticking method.
The air jet affixing method of (1) is a method in which the label peeled off from the mount and held on the label holding part is blown off to the product to be labeled by air jet and affixed to the product. It is characterized by sticking a label.
The pressure bonding method of (2) is a method in which the label peeled off from the mount and held on the label holding part is attached to the product by moving the label toward the product to be labeled by the pressure bonding member. It is characterized by sticking a label by pressing it onto a product.
[0003]
The methods {circle around (1)} and {circle around (2)} have their merits and demerits, and are used properly according to the situation of use. For example, in the case of a product that moves at high speed, a product that has an uneven label sticking surface and is not flat, and the like, when the label is stuck on the product reliably and accurately, the pressure bonding method of (2) is preferable.
[0004]
There are various structures of this pressure bonding method, but recently, a structure proposed in Japanese Patent Application Laid-Open No. 10-230917 has been adopted.
The label affixing device described in Japanese Patent Application Laid-Open No. 10-230917 has a plurality of pipe-like members arranged in parallel from above on a label peeled off from the mount and held on the label holding part by negative air pressure. By lowering the crimping member toward the product, the label is pressed against the product and stuck. Each pipe-shaped member constituting the crimping member can be independently slid in the axial direction, and when the pipe-shaped member comes into contact with the product, the pipe slides and an extra pressing force is applied to the product. There is no structure.
[0005]
[Problems to be solved by the invention]
Therefore, since the conventional label sticking apparatus described above is divided into a plurality of crimping members, even if the label sticking surface of the product is not flat, the label sticking can be performed reliably and accurately. In view of pressing the label against the product, the structure is devised so that an excessive pressing force is not applied to the product as much as possible, but it is inevitable that a certain amount of pressing force is applied to the product.
Therefore, there is a problem that this pressing force cannot be used for a product that deteriorates the quality of the product.
For example, when a label is attached to a wrapped pizza bread or the like, the wrap comes into contact with the topping of the pizza with a pressing force, and the commercial value is lowered.
[0006]
Also, when lowering the label sucked and held by the label holding part by lowering the crimping member, if the label does not break and the rear end of the label is not peeled off from the mount, the label will be The label sticking position may be disturbed, and in extreme cases, the label sticking may fail because the trailing edge of the label is attached to the mount, but the tip side only tilts downward and does not descend. . This is particularly a problem with small labels (for example, POP labels) that are difficult to peel off with a dispenser.
[0007]
In order to solve this problem, at the time of label production, the die-cutting (blade cutting) stroke for die-cutting of the label is strictly adjusted to prevent the blade from biting into the backing paper and worsening the glue breakage. Alternatively, a so-called transition label is used in which the once-punched label is peeled off from the mount and repositioned to a slightly shifted position so that the adhesive breakage is improved. For this reason, the label used was very expensive.
Moreover, even when the above-described label is used, the conventional label sticking apparatus cannot stick a label having a length of 25 mm or less stably and satisfactorily.
Recently, there is a user who desires automatic application of a label of about 15 mm because of the relationship with a product to which a POP label is applied, but the conventional label application device cannot answer such a user's request.
[0008]
The present invention has been made in view of the above-described problems of the prior art, and the object of the present invention is to select either a mechanism (system) of an air jet pasting mechanism or a crimp pasting mechanism according to the product. It is another object of the present invention to provide a label sticking apparatus that can stick labels.
Another object of the present invention is to provide a label sticking device capable of sticking a label by arbitrarily selecting an air jet sticking mechanism and a pressure sticking sticking mechanism.
Furthermore, another object of the present invention is to apply a label without using an expensive label such as a transition label and capable of stably and reliably affixing a small label, for example, a length of about 15 mm, which could not be applied conventionally. To provide an apparatus.
[0009]
[Means for Solving the Problems]
  The technical means taken by the present invention in order to achieve the above object is a label sticking device that peels off a label attached to a mount at predetermined intervals and automatically sticks the label to a predetermined position of a product. A plurality of label crimping members consisting of pipe shafts that can move up and down the labels peeled off from the mount.At least a part ofA pressure bonding mechanism for applying the label by pressing the label against the product with the pressure bonding member, and the label pressure bonding member at the label issuing position.By at least part ofAdsorbed and labeledPressureAn air jet affixing mechanism that moves the receiving member from the label issuing position toward the product and blows air from the pipe shaft toward the product to be labeled to apply the label to the product, Selection information of the pressure bonding mechanism or air jet bonding mechanism is set for each code, and the pressure bonding mechanism or air jet bonding mechanism is selected by inputting a product identification code (Claim 1).
  With this configuration, it is possible to apply a single label application device using either an air jet application method or a pressure application method according to the product to be applied.
[0010]
  That is,The air jet sticking method and the pressure sticking sticking method described above are alternatively selected according to the product to be attached.TheThereby, since a sticking method is selected according to goods, a sticking method suitable for goods is automatically selected.
  In addition, the selection of the pasting method is performed by setting the pasting method selection information for each product identification code in advance, and by inputting the product identification code, the air jet pasting mechanism (air jet method) or the crimp pasting mechanism (crimping method) is selected. Let it be selectedYes.Thus, the pasting method is automatically selected simply by inputting the product identification code (product number).
[0011]
  In the above air jet application method, after moving the label in the direction of the product from the label issuance position, the air is blown off and the label is attached to the product.TheThat is, since the air is blown after the label is moved to the vicinity of the product, the label can be accurately and reliably attached to a predetermined portion of the target product.
  The amount of movement from the label issuance position to the position at which air is blown against the label in the air jet pasting method can be changed according to the target product to be labeled (claim).2). Thereby, since the moving amount to the position where the air spraying is started on the label can be adjusted according to the product, the label can be applied by spraying from the optimum position according to the product.
  The amount of movement is set according to the height of the product (claim)3). Thereby, even when the heights of the products are different, the labels can be sprayed and pasted under the same conditions apart from the product surface by a certain distance.
[0012]
  The height of the product as a basis for setting the movement amount is set in advance for each product identification code, and the movement amount is automatically set by inputting the product identification code.4). Thereby, since the setting of the product height data is performed by inputting the product code, the height can be set without placing an extra burden on the operator.
  In addition to the method for setting the product height for each product identification code described above, the product height may be detected and set during the transfer of the product (claims).5). That is, a sensor for detecting the height of the product is arranged upstream from the label attaching position, and the movement amount is automatically set based on the height data detected by the sensor. In this case, since the product height data is automatically detected by the sensor during the product transfer process, the label movement amount should be adjusted according to the product height without setting it for each product identification code in advance. Can do.
[0013]
  The structure of the label affixing device having both the air jet affixing method and the pressure affixing affixing method includes a label holding surface that sucks and holds the surface opposite to the adhesive surface of the issued label with negative air pressure, A plurality of through holes formed in the label holding surface, and a label held on the holding surface by moving from the upper side to the lower side of the label holding surface through the through hole, the label holding surface It consists of a plurality of label crimping members that are moved downward in the product direction, and at least part of the label issuing side of the plurality of label crimping members is,Adsorption means for adsorbing labels with negative air pressureAnd air blowing means for blowing the label toward the product in a state where the label is moved and approached from the label holding surface toward the product.(Claims)6).
  With this configuration, since the label can be moved to the label holding surface by the suction means of the label pressing member, the label can be reliably peeled from the mount. As a result, it is possible to carry out label sticking stably and surely even with a small label in which glue breakage has been a problem.
[0014]
  or,Since the label pressure-bonding member includes the spraying means, it is possible to perform label sticking by an air jet sticking method with the constituent members of the pressure-bonding mechanism.
[0015]
  Further, the above-mentioned label pressing member may be a solid rod, but the cross-sectional shape is a circular pipe, and at least the pressing member provided with the suction means is provided with an air passage that generates negative suction pressure. In order to ensure the communication state, it is preferable to provide a rotation stop mechanism that stops the rotation in the circumferential direction.7). By providing this anti-rotation mechanism, the direction of the pressure-bonding member that adsorbs the label does not change, and the direction (posture) of the label can be held in a certain direction. That is, it is possible to prevent the label from being bent and attached.
[0016]
  Furthermore, it is desirable that the inner diameter of the air outlet of the circular pipe-shaped label crimping member provided with the suction means is larger than the inner diameter of the air outlet of another label crimping member not provided with the suction means (claim) Term8). Thereby, sufficient suction and blowing force of air can be obtained, and even a small label can be favorably peeled off and sprayed.
[0017]
  The specific structure of the suction means and the air blowing means includes a label holding surface that sucks and holds the surface opposite to the glue surface of the issued label with negative air pressure, and a plurality of labels formed on the label holding surface.

[0029]
FIG. 8 is a block diagram showing the configuration of the electrical drive unit of the label sticking device including the control unit 27 for controlling the operation of the label sticking device and the label issuing device B connected to the control unit 27. .
The control unit 27 includes a CPU (Central Processing Unit) 28, a ROM 29, a RAM 30, and a display / operation unit 31 connected to the CPU 28 via a bidirectional bus, and a label issuing unit via the bidirectional bus. 32. Crimping member driving part (air cylinder 7), label crimping member 9_-1The first electromagnetic valve driving unit 33 that switches between the suction unit 17 and the air blowing unit 18 included in the second electromagnetic valve, and the second electromagnetic valve driving unit that switches the operation / stop of the air blowing unit 18 included in all the label pressing members 9. 34 and the product detection part 35 are electrically connected.
[0030]
A control program executed by the CPU 28 is stored in the ROM 29 of the control unit 27. The RAM 30 stores various data necessary when the control program is executed, preset data of the label issuing device B, and the like. The data stored in the RAM 30 is the product file data shown in FIG. 9, and for each product number (product number), a product name, a unit price, and a labeling method flag (“0”: crimping, “1”: air jet) ), Product height data is provided. Accordingly, selection of the label affixing method for each product, and if the affixing method is the air jet affixing method, the movement from the initial position of the label crimping member 9 to the position where the label is affixed to the product by air blowing The amount is set automatically.
[0031]
Next, an outline of the control of the label sticking operation will be described based on the flowchart of FIG.
(Start): When the power switch of the labeling device A is turned on, the conveyor 1 for conveying the product is driven, and the exhaust device 11 of the labeling device A is driven, and the product number is input from the display operation unit 31. It will be in a standby state. Here, by inputting the product number, setting data such as the label attaching method and the product height “H” are read from the product file stored in the RAM 30 and set.
(SP10) ... It is detected whether or not the product a is present by the product detection unit 35 arranged upstream from the label sticking position of the transport table 1 ′ including the conveyor 1. If the presence of the product a is detected, the process proceeds to SP11.
[0032]
(SP11) ... When the product a is detected, the first electromagnetic valve driving unit 34 is operated to operate the label pressure bonding member 9_-1The label pressing member 9_-1A suction force is generated at the tip.
(SP12) A label is issued. In this embodiment, a pre-printed POP label is issued from a label issuing device B that does not include a printing unit. The issued label is sucked and held on the lower surface of the label holding face plate 10 of the label sticking apparatus A. This label adsorption and holding is performed by the negative pressure acting on the through hole 16 of the label holding face plate 10 by the operation of the exhaust device 11 and the label pressing member 9 located near the label issuing port._-1The label is sucked and held by the suction force of the suction means 17 provided in the above. If the issued label is small, the label crimping member 9_-1The suction means 17 sucks and holds the suction force.
[0033]
(SP13) ... It is checked whether or not a predetermined time has elapsed since the commodity a was detected. This predetermined time is the time required for the product to move to the application position (directly below the label crimping member) after the product is detected at SP10, and the label application timing is adjusted (see FIG. 11).
(SP14) ... The label pressing member 9 is lowered. At this time, the label pressing member 9_-1Is lowered in a state where the label is adsorbed and held, and even when the label is in a state where the adhesive is poor and the edge is attached to the mount, it is surely peeled off from the mount.
(SP15) ... It is determined whether or not the label sticking method is an air jet sticking method. If the determination result is YES, the process proceeds to SP16, and if NO (pressure bonding method), the process proceeds to SP22.
[0034]
(SP16)... When the determination result at SP15 is YES, it is determined whether the lowering of the label pressing member 9 has been lowered to the predetermined position (P) shown in FIG. As shown in FIG. 12, in the air jet pasting method, the distance (G) between the tip of the label pressing member 9 and the product a when the label is applied to the target product a by blowing air from the label pressing member 9 is Regardless of the height “H” of the target product, it is preferable that the interval is always constant. Therefore, the moving amount (P) of the label pressing member 9 is P = H₀Calculated by − (H + G). That is, based on the height “H” of the pasting target product “a”, it is calculated by the previous formula. H₀Is a structurally determined dimension, G is a preset constant, and H is set for each product. Further, the height “H” of the product a may be detected by a sensor arranged on the side of the transport table 1 ′. The operation of detecting the height of a product with a sensor is effective for a product whose height differs depending on the placement when the product is placed on a tray.
[0035]
(SP17) ... When the movement amount (P) reaches a predetermined amount, the lowering operation of the label pressing member 9 is stopped (see FIG. 14).
(SP18)... Operates the first and second solenoid valve drive units 33 and 34 to blow out air from the label pressurizing member 9 for a certain period of time, and blows off the label toward the product a located immediately below the label pressurizing member 9. . Since the air is blown toward the product by an air jet from a position near the upper surface of the product, the label is attached reliably and accurately.
(SP19) ... The label pressing member 9 is raised.
(SP20) ... It is checked whether the label pressing member 9 has been raised to the initial position, and it is detected that the label has been raised to the initial position.
[0036]
(SP21)... When it is detected that the label has been raised to the initial position, the rise of the label pressing member 9 is stopped. This completes one cycle of air jet pasting.
(SP22) ... When it is determined in SP15 that the label sticking method is not the air jet sticking method, it is determined whether or not the lowering of the label pressing member 9 has been lowered to the lower end (see FIG. 16).
(SP23) ... The lowering of the label pressing member 9 is stopped. Until this descent is stopped, the label is pressed against the product by the label pressing member 9 (in the state of the imaginary line in FIG. 16).
(SP24) ... Label crimping member 9_-1The suction operation by the suction means 17 is stopped by controlling the first electromagnetic valve driving unit 33. Then, after stopping the suction, the process proceeds to SP19, and thereafter, the process is executed up to SP21 and one cycle of label sticking by the pressure sticking sticking method is completed.
[0037]
As described above, (SP16) to (SP21) are label sticking by the air jet sticking method, and (SP22) to (SP24) (SP19) to (SP21) are label sticking by the pressure sticking sticking method.
And the sticking by an air jet sticking method and the sticking by a pressure bonding sticking method are automatically selected according to goods.
In the case of the air jet pasting method, the label pasting position (P) for blowing air is automatically set according to the height “H” of the product a.
The label held by the label holding face plate 10 is attached to the label pressing member 9._-1By lowering the label pressing member 9 while being adsorbed by the adsorbing means 17, the label can be surely peeled off from the mount even when the label has poor adhesiveness and the edge of the label is attached to the mount. Can do. Therefore, even a small label, which has been difficult to be pasted, can be pasted without using an expensive transition label.
And in the case of an air jet sticking method, since a label is moved to the vicinity of goods, and it sticks by spraying of air, label sticking can be performed correctly and reliably.
[0038]
In addition, the label sticking apparatus of this invention is not limited to embodiment mentioned above, The thing which added the following changes is also included.
(1) In the embodiment, the label issuing device does not have a printing unit, and a pre-printed label is used. However, the label issuing device has a printing unit and prints the product name, price, etc. on the label when issuing the label. You may do it.

【The invention's effect】
  The label sticking device of the present invention can be stuck by one label sticking device according to the structure of claim 1 by either an air jet sticking method or a pressure sticking sticking method according to the product to be stuck. As a result, in the pressure bonding method, when the value of the product is lowered due to the pressing force applied to the product at the time of label application, the range of products that can be applied is greatly expanded by applying the air jet method.
  AndSince the pasting method is selected according to the product, the pasting method suitable for the product is automatically selected.
  orBy simply inputting the product code (product number), the pasting method is automatically selected. This type of labeling device stores various data in advance corresponding to the product code, such as print data settings, and reads and sets various data set by inputting the product code when labeling is performed. It has been done conventionally. Therefore, the operator automatically selects the pasting method without performing extra operations as compared with the conventional case.

  MoreWhen a label is affixed by the air jet affixing method, since the air is blown after the label is moved to the vicinity of the product, the label can be affixed accurately and reliably.
  Claim2With the described configuration, the amount of movement (stroke) until air is blown onto the label can be adjusted according to the product, so that the label can be applied by spraying from an optimum position according to the product.
  Claim3By setting the amount of movement of the label crimping member according to the product according to the configuration described above, label sticking can be performed under the same conditions even when the height of the product is different.
  Claim4With the configuration described above, the product height data is set by inputting the product code, so that no extra burden is placed on the operator.
[0041]
  Claim5With the described configuration, the height data of the product is automatically detected by the sensor, so that the amount of movement of the label pressing member can be adjusted according to the height without setting in advance for each product code.
  Claim6With the described configuration, the label held on the label holding face plate is moved while being adsorbed by the label pressing member, so that the label can be completely peeled off from the mount. For this reason, in particular, it is possible to stably and surely apply a label even on a small label in which glue breakage has been a problem. For example, it becomes possible to affix a small label having a length of about 15 mm without using an expensive label such as a transition label.
  orSince the label pressure-bonding member is provided with air blowing means, it is possible to perform label sticking by an air jet sticking method instead of a pressure sticking sticking method.
[0042]
  Claim7With the described configuration, the posture (orientation) of the label does not change even when a small label is attached. That is, when the label pressure-bonding member that sucks and holds the label rotates, the label also rotates and bends and is stuck, but by stopping the rotation of the label pressure-bonding member, the bent sticking can be prevented.
  Claim8With the configuration described above, in the case of a small label, since the label is moved and sprayed only with the label pressing member provided with the suction means, the label can be peeled off and sprayed well even with the small label. Further, it is possible to obtain a configuration that can sufficiently obtain air suction and blowing force.
