Description

  The present invention relates to a label sticking apparatus that peels off a label from a strip and mounts it on a suction plate to stick the label. In particular, the present invention relates to a label using a suction plate by injecting air from the back side of a peeled label with an air jet pipe. The present invention relates to a label sticking device that assists in adsorbing water.

  Conventionally, as this type of label sticking device, for example, as shown in FIG. 5, a belt-like mount D sent from a label delivery section (not shown) having a supply reel is folded and temporarily attached to the belt-like mount D. The peeling member 100 having an edge 101 for peeling the label L, and the suction position X for sucking the label L peeled by the peeling member 100 from the front side to the suction surface 102 and the sucked label L are not shown. The suction plate 103 that is moved to the affixing position Y to be affixed to the adhering plate, and the air from the back side of the label L that is fixed to the exfoliation member 100 and is exfoliated from the exfoliation member 100 at the adsorption position X of the adsorption plate 103 toward the adsorption plate 103 side. There is known an air jet pipe 104 that jets and assists the suction of the label L by the suction plate 103 (see, for example, JP-A-2006-143234). ). In FIG. 5, reference numeral 105 denotes a print head that performs printing on a label L temporarily attached to the belt-like mount D in front of the peeling member 100, and 106 denotes a platen.

JP 2006-143234 A

  By the way, in this conventional label affixing device, when the belt-like mount D is mounted, the tip portion Da is passed between the print head 105 and the platen 106 by manual work one by one, and this is placed on the suction plate 103 side. Since the tip end portion Da protrudes and the belt-like mount D is folded back at the edge 101 of the peeling member 100, the tip end portion Da must be passed between the peeling member 100 and the air ejection pipe 104. There was a problem that the work was complicated. In particular, the protruding end portion Da of the belt-like mount D covers the air ejection pipe 104, and since the space between the peeling member 100 and the air ejection pipe 104 is narrow, the air ejection pipe 104 becomes an obstacle, and the belt-like mount. The work of folding and mounting D is extremely complicated.

  The present invention has been made in view of the above problems, and when the belt-like mount is mounted, the tip of the belt-like mount protruding toward the suction plate side can be easily folded back so that the air ejection pipe does not get in the way. It is an object of the present invention to provide a label sticking device that can be attached and that improves the workability of attaching a belt-like mount.

In order to solve the above-mentioned problem, a label sticking device of the present invention includes a peeling member having an edge for turning back a belt-like mount sent from a label sending unit and peeling a label temporarily attached to the belt-like mount, and the peeling member From the back side of the label peeled off from the peeling member that is positioned near the edge of the peeling member and outside the folded strip-like backing sheet, the suction plate that sucks the peeled label from the front side to the suction surface In a label sticking apparatus provided with an air injection pipe for injecting air toward the suction plate side and assisting suction of the label by the suction plate, the suction plate and the air injection pipe are supported by one support member, A configuration in which the air injection pipe is movable to two positions, a spray position for spraying air located near the edge of the peeling member and a spaced position spaced from the peeling member, via a support member; To have.

Thus, when the belt-like mount is attached, the air ejection pipe is moved from the ejection position to the separated position. In this case, the suction plate is also moved because it is moved via the support member. In this state, the front end of the belt-like mount is projected from the edge of the peeling member toward the suction plate, and the projected front end is folded back with the edge of the peeling member as a boundary. When the front end portion of the belt-like mount protrudes, the air ejection pipe is separated from the peeling member, so that the front end portion is less likely to hit the air ejection pipe, and the projection is reliably performed. In particular, since the suction plate is also separated through the support member, it is possible to reliably prevent the front end of the belt-like mount from interfering with the suction plate, and to reliably project the front end of the belt-like mount. Become.
Further, when the protruding tip portion is folded back, the air ejection pipe is not easily disturbed, and the tip portion is easily folded back. Therefore, it becomes easy to mount the belt-like mount, and the mounting workability is greatly improved. In particular, since the suction plate is also separated through the support member, the space is widened, and the tip portion is easily folded back accordingly.

Then, if necessary, the separation position of the air jet tube is set so as to be located further outside the label temporary attachment side surface of the belt-like mount protruding from the peeling member when the belt-like mount is mounted. ing.
Thereby, when the belt-like mount is mounted, the tip of the belt-like mount is protruded from the edge of the peeling member to the suction plate side and folded, and at this time, when the air ejection pipe is moved from the separation position to the ejection position, In this movement process, the air jet tube pushes the leading end of the belt-like mount, and as a result, the belt-like mount is automatically folded back, making it easier to mount and greatly improving the mounting workability.

  Moreover, it is set as the structure provided with the air injection pipe drive part which moves the said air injection pipe to 2 positions of the said injection position and a separation position as needed. Since the air injection tube can be automatically moved to the two positions of the injection position and the separation position by the air injection tube driving unit, the operation becomes easier as compared with the case of manually moving the air injection tube.

  Further, if necessary, the belt is provided with a transport roller for transporting the belt-like mount and a mount sensor for detecting the presence or absence of the belt-like mount in front of the peeling member. When the presence of a part is detected, the conveying roller is driven for a predetermined time, and the air injection pipe is moved from the injection position to the separation position, and then the air injection pipe is moved from the separation position to the injection position after a predetermined time has elapsed. It is set as the structure provided with the control part which act | operates an air injection pipe drive part so that it may make. By simply inserting the leading edge of the belt-like mount into the conveying roller, automatic conveyance (auto feed) is performed by the conveying roller, and further, the air jet tube driving unit is automatically driven until the leading end is folded back. The mounting becomes easier and the mounting workability is improved.

According to the label sticking device of the present invention, when the belt-like mount is mounted, the air ejection pipe is moved from the ejection position to the separated position, and in this state, the leading end of the belt-like mount is moved from the edge of the peeling member to the suction plate side. The protruding tip is folded back with the edge of the peeling member as the boundary, but since the air injection pipe is separated from the peeling member, the tip becomes difficult to hit the air ejection pipe, It can be done reliably. In particular, since the suction plate is also separated through the support member, it is possible to reliably prevent the front end of the belt-like mount from interfering with the suction plate, and to reliably project the front end of the belt-like mount. Become.
Also, when the protruding tip portion is folded back, the air ejection tube is not easily disturbed, and the tip portion can be easily folded, and in particular, the suction plate is also separated through the support member. The space becomes wider and the tip portion can be easily folded back. Therefore, it is easy to mount the belt-like mount, and the mounting workability can be greatly improved.

  In addition, when the separation position of the air jet tube is set to be located at a position further outside the surface on the label temporary attachment side of the belt-like mount protruding from the peeling member when the belt-like mount is mounted, When mounting the mount, the tip of the strip mount is folded back by protruding from the edge of the peeling member to the suction plate side.At this time, if the air injection tube is moved from the separation position to the injection position, this movement process Since the air jet tube pushes the leading end of the belt-like mount, the belt-like mount is automatically folded back, and the mounting becomes easier and the mounting workability can be greatly improved.

It is moved by the air cylinder device 25 to a pasting position Y to be pasted on (not shown). The air cylinder device 25 includes a cylinder 25a and a piston 25b, and is fixed to a support member 33 described later via a support member 26. A base 22 to which a suction plate 20 is attached is attached to the tip of the piston 25b.

  Furthermore, the label sticking device according to the embodiment includes an air injection pipe 30 that assists the suction of the label L by the suction plate 20 at the suction position X of the suction plate 20. As shown in FIG. 1, the air injection pipe 30 includes a pipe main body 31 having an axis parallel to the direction of the edge 11 of the peeling member 10, and an injection that injects air into the pipe main body 31 along the axial direction. As shown in FIG. 2, a plurality of ports 32 are formed, and the label L is peeled off from the peeling member 10, located near the edge 11 of the peeling member 10 and outside the folded strip D. Air is jetted from the back side toward the suction plate 20 side.

  One end of the air injection tube 30 is supported by the support member 33. That is, the suction plate 20 and the air injection pipe 30 attached to the tip of the piston 25 b of the air cylinder device 25 are supported by one support member 33. Then, the air injection pipe 30 is located near the edge 11 of the peeling member 10 through the support member 33, and the jetting position F (FIGS. 2, 3A, 3C) for jetting air and the peeling. It is movably provided at two positions of a separation position G (FIG. 3B) that is separated from the member 10.

  Specifically, a base plate 34 that extends from the machine base 1 is provided adjacent to the support member 33, and the support member 33 has an air injection pipe 30 at an injection position F and a separation position 2 relative to the base plate 34. It is provided so that it can move to a position. A slider 35 protruding from the base plate 34 is fixed to the support member 33, while a guide hole 36 through which the slider 35 penetrates and guides the movement of the support member 33 through the slider 35 is fixed. Is formed. The inclination angle of the guide hole 36 is determined so that the air injection tube 30 can move forward and backward in an inclined direction that is inclined with respect to the direction of the suction surface 21 of the suction plate 20. Then, the separation position G of the air ejection tube 30 is located at a position further outside the surface on the temporary attachment side of the label L of the belt-like mount D protruding from the peeling member 10 when the belt-like mount D is mounted. Is set.

  The air injection pipe 30 is moved to two positions of an injection position F and a separation position G by the air injection pipe driving unit 40. The air injection pipe drive unit 40 includes an air cylinder device 41 including a cylinder 41a and a piston 41b. The cylinder 41a is fixed to the base plate 34, and a slider 35 is attached to the tip of the piston 41b. When the piston 41b of the air cylinder device 41 is retracted, the air injection tube 30 is positioned at the injection position F, and when the piston 41b of the air cylinder device 41 is advanced, the air injection tube 30 is positioned at the separation position G.

  Further, the label sticking device according to the embodiment detects the presence or absence of the belt-like mount D when the belt-like mount D is attached, that is, when the belt-like mount D is attached from the state where there is no belt-like mount D on the mount transport path. Based on the detection of the mount sensor 6, a control unit (not shown) for controlling the platen 3 that transports the belt-shaped mount D, the transport roller 5, and the air ejection pipe driving unit 40 is provided. When the mount sensor 6 detects the presence of the leading end of the strip mount D when the strip mount D is mounted, the control section drives the platen 3 and the transport roller 5 for a predetermined time, and sets the air ejection pipe 30 to the ejection position. Then, the air injection pipe driving unit 40 is operated so that the air injection pipe 30 is moved from the separation position G to the injection position F after a predetermined time has elapsed.

  Therefore, in the label sticking device according to the embodiment of the present invention, when the belt-like mount D is attached, the following is performed. Explaining also with reference to the flowchart of the control by the control unit shown in FIG. 4, in the state where there is no strip-shaped mount D on the mount transport path, the mount sensor 6 always looks at the presence or absence of the strip-shaped mount D (S01). In this state, as shown in FIG. 3A, first, the belt-like mount D is pulled out from the label sending portion, and the leading end portion Da is inserted into the transport roller 5. As a result, the mount sensor 6 detects the mount (S01Y), and as shown in FIG. 3B, the platen 3 and the transport roller 5 are driven, and the air injection tube driving unit 40 is operated to operate the air injection tube. 30 is moved from the injection position F to the separation position G (S02). As a result, the tip end portion Da of the belt-like mount D passes through the edge 11 of the peeling member 10 and protrudes toward the suction plate 20.

  In this case, the suction surface 21 of the suction plate 20 is positioned so that the separation position G of the air ejection tube 30 is located further on the outer side than the temporary attachment side surface of the label L of the belt-like mount D protruding from the peeling member 10. Therefore, it is possible to prevent the front end portion Da of the belt-like mount D from interfering with the air injection tube 30. In particular, since the suction plate 20 is also separated through the support member 33, it is possible to reliably prevent the front end portion Da of the strip-shaped mount D from interfering with the suction plate 20, and the front end portion Da of the strip-shaped mount D is surely secured. It can be made to protrude.

The platen 3 and the transport roller 5 are driven for a predetermined time (S03), and when the predetermined time has passed (S03Y), the drive of the platen 3 and the transport roller 5 is stopped (S04). As a result, as shown in FIG. 3C, the belt-like mount D protrudes for a required length, and the leading end Da faces the downstream side of the peeling member 10. At this time, the air injection tube drive unit 40 is operated to move the air injection tube 30 from the separation position G to the injection position F (S04). The suction plate 20 is also located at the suction position X.
In this case, the separation position G of the air ejection pipe 30 is located at a position further outside the surface on the temporary attachment side of the label L of the belt-like mount D protruding from the peeling member 10. In the process of moving to the position F, the air ejection tube 30 pushes the tip end portion Da of the belt-like mount D, whereby the belt-like mount D is automatically folded. For this reason, it is not necessary to fold the tip end portion Da one by one by hand, so that the mounting becomes easier.
Thereafter, the tip end portion Da of the belt-like mount D is manually attached to the take-up reel side.

  In the above-described embodiment, the configuration of the air injection tube driving unit 40 is not limited to the above-described configuration, and any mechanism may be used such as a mechanism such as a rack and pinion. Of course. Moreover, in the said embodiment, although the air injection pipe drive part 40 was provided, it is not necessarily limited to this, You may comprise so that the supporting member 33 may be moved manually, without providing in particular.
