A movement path is set so that one end of the outer peripheral surface of the barrel contacts one end of the label adsorbed by the bell adsorbing device, and the power source control device for the label adsorbing device is connected to the outer peripheral surface of the barrel. When the contact of one end of the label occurs, the moving speed of the label becomes substantially the same as the moving speed of the barrel support device, and thereafter, the moving speed of the label exceeds the moving speed of the barrel support device. The power source for the label adsorbing device is controlled so that rotation of the barrel on the device and winding of the label around the barrel occur.

  According to this configuration, since one end of the label comes into contact with a fixed position on the outer peripheral surface of the barrel, the label can be attached at a certain angular position on the outer peripheral surface of the barrel. Also, the label moving speed is such that one end of the label is brought into contact with the outer peripheral surface of the barrel in a state where the moving speed of the label is substantially equal to the moving speed of the syringe, and then the barrel is rotated and the label is wound around the barrel. Since the label is suddenly brought into contact with a non-rotating barrel at a high speed, the label application start position is not shifted due to slip or the like. Also, the label is smoothly wound around the barrel, and the label is not wrinkled.

It is characterized by controlling the feeding of the release tape as wear.

  According to this configuration, since the label can be adsorbed at a predetermined position on the label adsorbing surface, one end of the label can be brought into contact with a target location on the outer peripheral surface of the barrel.

  Further, the present invention provides a label adhering device for a syringe having the above-described configuration, comprising a label adsorbing device recognizing device for recognizing the position of the label adsorbed on the label adsorbing surface for each label, The power source control device controls the movement of the label suction device based on the label position information output from the label suction device recognition device so that one end of the label contacts a predetermined location on the outer peripheral surface of the barrel. It is characterized by that.

  According to this configuration, it is possible to improve the positional accuracy when the one end of the label is brought into contact with the target location on the barrel outer peripheral surface.

  The present invention is also directed to a device for applying a label to a syringe having the above-described configuration, wherein the label suction device includes an air suction device and a suction belt wound around the air suction device, and air is sucked through the suction belt.

It is sectional drawing which shows the structural example of a syringe. FIG. 12 is an end view of a barrel included in the syringe of FIG. 11. It is a side view which shows the state which stuck the label on the syringe of FIG.

  1st Embodiment of this invention is described based on the figure from FIG. 1 to FIG. The main elements constituting the label sticking device 1 are a barrel support device 10 for supporting the barrel 101 of the syringe 100 shown in FIGS. 11 to 13, a label suction device 20 for sucking and sticking the label 110 to the barrel 101, and The label supply device 30 supplies the label 110 to the label suction device 20.

  The barrel support device 10 is configured as a conveyor in which a plurality of buckets 11 are connected. Each bucket 11 supports one barrel 101 horizontally. The bucket 11 supports the barrel 101 with two support rollers 12, and the barrel 101 is supported by the bucket 11 so as to be rotatable around the axis of the barrel 101 itself and in an initial posture in which the flange 104 faces a predetermined angle. . The barrel support device 10 moves horizontally from right to left in FIG. The axis of the barrel 101 is perpendicular to the direction of movement of the barrel support device 10.

  The label suction device 20 vacuum-sucks the label 110 with the adhesive surface of the label 110 facing outward, and is composed of an air suction device and a suction belt wound around the air suction device. In this embodiment, two components constitute an air suction device. The first component is an air suction drum 21, and the second component is a wedge-shaped air suction block 22 disposed under the air suction drum 21. The air suction drum 21 rotates around the horizontal axis, but the air suction block 22 remains in the stationary position. The suction belt 24 is wound around the outside of the air suction drum 21 and the air suction block 22 to which the idle pulley 23 is added.

  The adsorbing belt 24 is configured to allow air to pass therethrough by perforating a belt material that does not allow air to pass through or by using a belt material that has air permeability. When the air suction drum 21 and the air suction block 22 suck air through the belt 24, the surface of the suction belt 24 functions as the label suction surface 25. The air suction drum 21 sucks air in a section including a point from the point where the label 110 is delivered from the label supply device 30 to a point where the suction belt 24 moves away from the outer peripheral surface of the drum. The air suction block 22 sucks air in a section including a point from a point where the suction belt 24 separated from the outer peripheral surface of the air suction drum 21 contacts the air suction block 22 to a point where the sticking of the label 110 to the barrel 101 is completed. To do.

  The label supply device 30 uses the peeling tape 31 as label supply means. The release tape 31 is made of release paper, and a label 110 is attached to the surface with the adhesive force of the adhesive surface. The peeling tape 31 is fed from a feeding spool 32 and wound around a take-up spool 33, and is wound around the peeling blade 34 in the middle. The angle of the peeling blade 34 can be adjusted with the end close to the feeding spool 32 as a fulcrum, and the tip forming a sharp edge approaches one point of the suction belt 24 on the air suction drum 21 from the tangential direction.

  The peeling tape 31 wound around the peeling blade 34 changes its direction at a steep angle at the tip of the peeling blade 34. At this time, the adhesive surface of the label 110 is peeled off from the release tape 31, and the label 110 is separated from the release tape 31. The label 110 is adsorbed on the label adsorbing surface 25 of the adsorbing belt 24 with the adhesive surface facing outward.

  The label supply device 30 is provided with a label supply device recognition device 35 that recognizes the label position on the peeling tape 31 for each label 110. Hereinafter, in the present specification, the shorter name “first recognition device” is used instead of the long name “recognition device for label supply device”. The first recognition device 35 includes a camera that captures an image of the label 110 and an analysis unit that analyzes image information from the camera. In FIG. 1, the camera figure symbolizes the entire first recognition device 35.

  The control device 40 shown in FIG. 5 controls the label sticking device. The control target of the control device 40 includes a barrel support device power source 13 for moving the barrel support device 10 relative to the label suction device 20, and a barrel in which the label suction surface 25 of the label suction device 20 is supported by the barrel support device 10. A label suction device power source 26 that moves relative to 101 and a label supply device power source 36 that feeds the peeling tape 31 of the label supply device 30 are included. That is, the control device 40 is a barrel support device power source control device, a label suction device power source control device, and a label supply device power source control device. In the following description, in place of the long name “barrel support device power source”, the shorter “first power source” is used, and instead the long name “label adsorption device power source” is used. The short name “second power source” is used, and the short name “third power source” is used instead of the long name “power source for label supply device”. The control device 40 receives information from the first recognition device 35 and outputs an operation command to the first recognition device 35.

  The first power source 13, the second power source 26, and the third power source 36 are all configured by motors. The first power source 13 tacts the plurality of buckets 11. The second power source 26 rotates the air suction drum 21. The third power source 36 rotates the take-up spool 33.

  The operation of the label sticking device 1 is as follows. The control device 40 drives the first power source 13, the second power source 26, and the third power source 36, and causes the barrel support device 10 to move along the line A in FIG. A movement of line B in FIG. 6 is generated on the suction surface 25, and a movement of line C in FIG. 6 is generated on the peeling tape 31 of the label supply device 30.

  The barrel support device 10 moves forward by an arrangement interval of the buckets 11, that is, one pitch at a predetermined speed while the tact phase advances from 0 ° to 360 °. One end of the label 110 adsorbed on the label adsorbing surface 25 as shown in FIG. 2 is formed at one location on the outer peripheral surface of the barrel 101 to which the label 110 has not yet been affixed in the process of moving the barrel support device 10. Contact. The movement path of the barrel support device 10 is set as such.

  As shown in FIG. 2, the bottom surface of the air suction block 22 is lifted as an inclined surface on the side facing the barrel 101, and is switched to a horizontal plane at the bent portion 22 a. The suction belt 24 is also bent following the shape of the bottom surface of the air suction block 22, and contact between one end of the label 110 and one place on the outer peripheral surface of the barrel 101 occurs at the bent portion. As described above, since the barrel 101 is supported by the barrel support device 10 in an initial posture in which the flange 104 faces a predetermined angle, one end of the label 110 comes into contact with a predetermined portion of the outer peripheral surface of the barrel 101.

  As indicated by line B in FIG. 6, the label suction surface 25 moves at a high speed at a tact phase of 0 °, but the speed drops rapidly from there. Eventually, the moving speed of the label suction surface 25 becomes substantially equal to the moving speed of the barrel support device 10. When the movement speed of the barrel support device 10 and the movement speed of the label suction surface 25 are compared in this way, the movement speed of the label suction surface 25 is compared with a speed component in the same direction as the movement direction of the barrel support device 10. Shall be performed.

  As described above, when the moving speed of the label suction surface 25 becomes substantially equal to the moving speed of the barrel support device 10, that is, the moving speed of the label 110 becomes substantially equal to the moving speed of the barrel support device 10. At some point, contact of one end of the label 110 with the outer peripheral surface of the barrel 101 occurs. Although it means “almost” of “almost constant speed”, it can be included in the range without any problem as long as it is within ± 10% of the moving speed of the barrel support device 10.

  As described above, after the end of the label 110 is brought into contact with the outer peripheral surface of the barrel 101 when the moving speed of the label 110 becomes substantially equal to the moving speed of the barrel support device 10, as shown by line B in FIG. The speed of the label suction surface 25 is increased. That is, the moving speed of the label 110 exceeds the moving speed of the barrel support device 10. Then, as shown in FIG. 3, the label 110 on which the sticking by the adhesive surface has started is wound around the barrel 101 while rotating the barrel 101 around the axis of the barrel 101 on the barrel support device 10. Eventually, the label 110 is completely wound around the barrel 101 as shown in FIG. The winding is completed before the tact phase reaches 360 ° in FIG.

  The barrel 101 in which the label 110 is completely wound then moves to the left in FIG. 4 while moving the barrel support device 10 and moves away from the suction belt 24. The suction belt 24 may contact the barrel 101 until the barrel 101 is completely separated from the suction belt 24, but the contact of the suction belt 24 only causes the barrel 101 to rotate about its own axis. The label 110 is not adversely affected.

  The inconvenience when one end of the label 110 comes into contact with the barrel 101 in a state where the moving speed of the label 110 is not reduced to substantially the same speed as the moving speed of the barrel support device 10 will be described with reference to FIGS. In such a case, since the barrel 101 cannot immediately follow the movement of the label 110 due to its own inertia, it acts as a brake against the movement of the label 110. Therefore, as shown in FIG. 7, a situation in which the slack 110a is often caused by the label 110 being pushed by the suction belt 24 behind the contact point with the barrel 101 can occur.

  As shown in FIG. 7, when the label 110 having the slack 110a is wound around the barrel 101, the slack 110a becomes wrinkles 110b as shown in FIG. The syringe 100 in which the wrinkles 110b of the label 110 are generated must be treated as a defective product.

  On the other hand, in the present invention, since one end of the label 110 is brought into contact with the outer peripheral surface of the barrel 101 when the moving speed of the label 110 becomes substantially equal to the moving speed of the barrel support device 10, the label 110 is attached by slipping or the like. The starting position does not shift. Then, since the label 110 is rotated by increasing the moving speed of the label 110 to wind the label 110, the label 110 is smoothly wound around the barrel 101, and the label 110 is not wrinkled.

  In FIG. 6, the surface pattern of the label 110 and the manner in which the label 110 moves away from the peeling blade 34 after reaching the edge of the peeling blade 34 are schematically shown at a position between the line A and the line C. ing. A recognition mark 112 is printed on one corner of the surface of the label 110. The first recognition device 35 detects the recognition mark 112 at the position of the recognition line represented by the one-dot chain line 36 in FIG. 6 and recognizes the label position on the peeling tape 31 for each label 110. The label position information is output to the control device 40, and the control device 40 controls the feeding of the peeling tape 31 based on the label position information. As a result, the label 110 can be attracted to a predetermined position of the label attracting surface 25.

  9 and 10 show a second embodiment of the label sticking device 1. The second embodiment is characterized in that the following components are added to the label sticking device 1 of the first embodiment. It is a label suction device recognition device 27 that recognizes the position of the label 110 sucked on the label suction surface 25 for each label 110. Hereinafter, in this specification, the shorter name “second recognition device” is used instead of the long name “recognition device for label adsorption device”. The second recognition device 27 includes a camera that captures an image of the label 110 and an analysis unit that analyzes image information from the camera. In FIG. 9, as with the first recognition device 35 in FIG. 1, the camera figure symbolizes the entire second recognition device 27.

  Based on the label position information output from the second recognition device 27, the control device 40 controls the movement of the label suction device 20 so that one end of the label 110 contacts a predetermined location on the outer peripheral surface of the barrel 101. Thereby, the position accuracy when making the end of the label 110 contact the target location on the outer peripheral surface of the barrel 101 can be improved.

  In both the first embodiment and the second embodiment, the label suction device 20 includes the air suction drum 21 and the air suction block 22 and the suction belt 24 wound around them. However, a label suction device having a different configuration is employed. It is also possible to do. For example, the label suction device can be configured by only the air suction drum, and the outer peripheral surface of the air suction drum can be directly used as the label suction surface. In that case, the barrel 101 to which the label 110 is to be attached is allowed to pass through a position facing the outer peripheral surface of the air suction drum over a predetermined time, and one end of the label 110 is at a low speed during the predetermined time. The operation of contacting the outer peripheral surface of 101 and then increasing the rotational speed of the air suction drum and rotating the barrel 101 and winding the label 110 around the barrel 101 may be generated.

  Although the embodiments of the present invention have been described above, the scope of the present invention is not limited to these embodiments, and various modifications can be made without departing from the spirit of the invention. Moreover, the quantity and numerical value which appear in this specification are an example to the last, and do not limit invention.

  The present invention can be used in a device for applying a label to a syringe.
