In the thermal labeler 50 to be attached, a battery supply device 52 and a battery carry-out device 53 are respectively arranged on both sides of the sticking drum 51, and the dry battery C is conveyed to the label sticking position by the battery feed device 52, and the label sticking position. , The dry battery C having the heat-sensitive adhesive label affixed to the outer peripheral surface of the trunk is carried out by the battery carrying-out device 53.

  These battery supply devices 52 include an upstream transport unit 60A and a downstream transport unit 70A that transport while holding the dry battery C using the magnetic attractive force of the magnet, and the battery carry-out device 53 receives the magnetic attractive force of the magnet. An upstream transport unit 60B and a downstream transport unit 70B that transport and hold the dry battery C are mounted, and the dry battery C is transferred between the upstream transport unit 60A and the downstream transport unit 70A. In addition, the delivery of the dry cell C is performed between the upstream transport unit 60B and the downstream transport unit 70B.

  The upstream transport units 60A and 60B and the downstream transport units 70A and 70B are rotationally driven by a drive motor (not shown) as shown in FIGS. 14 (a) and 14 (b) and FIGS. 15 (a) and 15 (b). A plurality of fitting recesses 62 and 72 into which the body of the dry battery C is fitted are embedded in star wheels 61 and 71 formed on the outer edge, and the fitting recesses 62 and 72 of the star wheels 61 and 71, respectively.

  However, as described above, even if the magnetic attraction force of the fitting recess 62 of the star wheel 61 is smaller than the magnetic attraction force of the fitting recess 72 of the star wheel 71, the guide member 81 causes the star wheel 61 to When the battery C is forcibly separated from the fitting recess 62, a large force is applied to the battery C, and there is a problem that the battery C is easily damaged. In particular, since the heat-sensitive adhesive label formed of the synthetic resin film is affixed to the dry battery C transported by the battery carry-out device 53, the heat-sensitive adhesive label is damaged due to contact with the guide member 81. There is a problem of receiving.

  In particular, the magnetic attractive force of the fitting recess 72 of the star wheel 71 of the downstream transport units 70A and 70B is larger than the magnetic attractive force of the fitting recess 62 of the star wheel 61 of the upstream transport units 60A and 60A. When the battery C is forcibly pulled away from the fitting recess 72 of the star wheel 71 by the guide member 82 in order to deliver the dry battery C from the downstream transport unit 70B in the battery carry-out device 53 to the carry-out conveyor.

  Hereinafter, embodiments will be described with reference to the drawings. FIG. 1 shows a method for forming a label having a predetermined length by sequentially cutting a long strip-shaped label-forming substrate M in which a heat-sensitive adhesive label (hereinafter referred to as a label) having a predetermined length is continuously connected. A thermal labeler 1 is illustrated in which the labels are sequentially attached so as to be wound around the outer peripheral surface of the body of the dry battery C conveyed to a predetermined label attaching position.

  As shown in the figure, the thermal labeler 1 forms a label L while sequentially cutting a long label forming substrate M wound in a roll shape, and sequentially supplies the label L to a label supply position. The label supply device 2, the label application device 4 for applying a label to the outer peripheral surface of the body of the dry battery C in the label application section α of the application drum 4a, and the label L supplied by the label supply device 2 and receiving the label L. A delivery drum 3 that is handed over, a battery supply device 5 that supplies a dry battery C to the label sticking device 4, and a battery carry-out device 6 that discharges the dry battery C to which the label L is stuck by the label sticking device 4. The upstream battery transport unit and the downstream battery transport unit respectively mounted on the battery supply device 5 and the battery carry-out device 6 are the transport unit of the present invention. This is. Hereinafter, the battery supply device 5 and the battery carry-out device 6 will be described in detail.

  As shown in FIGS. 1 and 2, the battery supply device 5 receives an upstream battery transport unit 10A that receives a dry battery C from the stocker 5a and transports it to an intermediate delivery position β2 at an initial delivery position β1, and an intermediate battery delivery unit 10A. A downstream battery transport unit 20A that receives the dry battery C from the upstream battery transport unit 10A at the delivery position β2 and transports it to the last delivery position β3 that is the start position of the label pasting section α in the pasting drum 4a is provided. In the final delivery position β3, the dry battery C is delivered from the downstream battery transport unit 20A to the label applicator 4. For the upstream battery transport unit 10A, the first delivery position β1 corresponds to the first delivery position of the present invention, the intermediate delivery position β2 corresponds to the second delivery position of the present invention, and the downstream battery transport unit 20A. Therefore, the intermediate delivery position β2 corresponds to the first delivery position of the present invention, and the last delivery position β3 corresponds to the second delivery position of the present invention.

  As shown in FIGS. 3 to 8, the upstream battery transport unit 10A and the downstream battery transport unit 20A are rotatable to a base plate 1a of the thermal labeler 1 and a support plate 5b attached to the base plate 1a. Rotation drive shafts 11 and 21 supported and driven by a motor (not shown), circular support bases 12 and 22 fixed to the rotation drive shafts 11 and 21, and bolted to the support bases 12 and 22 The base members 12, 22 are sandwiched between a pair of front and rear synthetic resin star wheels 13, 13, 23, 23 and a pair of front and rear synthetic resin star wheels 13, 13, 23, 23. Magnet wheels 15 and 25 supported so as to be relatively rotatable via bearings 14 and 24, and a star wheel 3 and 23, the number of the fitting recess 13a of battery C is fitted to the outer edge, 23a are formed.

  The magnet wheels 15 and 25 basically have a slight gap formed between their respective outer peripheral surfaces and the dry cells C and C fitted into the fitting recesses 13a and 23a of the star wheels 13 and 23. Although the outer diameter is set, the magnet wheel 25 of the downstream battery transport unit 20A adjacent to the sticking drum 4a of the label sticking device 4 is one of the sticking guides 4b in the label sticking device 4 after the last delivery position β3. The recessed part 25a which receives the edge part of this is partially formed.

  Further, the magnet wheel 15 has a region extending from the first delivery position β1 on the outer peripheral surface to a position immediately before the intermediate delivery position β2 in the rotational direction of the star wheel 13, and the magnet wheel 25 has an intermediate position on the outer peripheral surface. Permanent magnets 16 and 26 are respectively embedded in regions extending from the delivery position β2 to the position immediately before the last delivery position β3 in the rotation direction of the star wheel 23, and by the magnetic attractive force of the permanent magnets 16 and 26, The dry battery C fitted into the fitting recesses 13a, 23a of the star wheels 13, 23 is held in that state.

  The permanent magnets 16 and 26 embedded in the magnet wheels 15 and 25 are three, two, three, two, etc. in the circumferential direction of the magnet wheels 15 and 25 as shown in FIGS. Although they are alternately arranged, three permanent magnets 16 and 26 are arranged at the first delivery position β1 in the magnet wheel 15 and the middle delivery position β2 in the magnet wheel 25. The permanent magnets 16 and 26 are embedded in the position immediately before the delivery position β2 and the position immediately before the last delivery position β3 of the magnet wheel 25 so that the two permanent magnets 16 and 26 are arranged.

  In addition, stopper pins 17 and 27 are screwed into areas where the permanent magnets 16 and 26 are not embedded in the outer peripheral surfaces of the magnet wheels 15 and 25, and the stopper pins 17 and 27 serve as the base plate 1 a of the thermal labeler 1. The magnet wheels 15 and 25 are prevented from rotating by being fitted into the concave grooves 18a and 28a of the flat bars 18 and 28 attached to. Therefore, even if the rotational drive shafts 11 and 21 rotate, the magnet wheels 15 and 25 do not rotate, and only the pair of star wheels 13, 13, 23, and 23 rotate.

  In the battery supply device 5 configured as described above, the dry battery C supplied from the stocker 5a to the first delivery position β1 is fitted into the fitting recess 13a of the star wheel 13 in the upstream battery transport unit 10A. It is held by the magnetic attraction force of the permanent magnet 16 embedded in the magnet wheel 15, and is transported to the intermediate delivery position β2 in this state. At the intermediate delivery position β2, the star wheel 23 is fitted in the downstream battery transport unit 20A. The recess 23a is also fitted.

  Only two permanent magnets 16 are embedded immediately before the intermediate delivery position β2 on the outer peripheral surface of the magnet wheel 15 of the upstream battery transport unit 10A, and the permanent magnet 16 is placed at the intermediate delivery position β2. Is not buried, the magnetic attractive force decreases immediately before the intermediate delivery position β2, and the suction holding of the dry cell C with respect to the star wheel 13 of the upstream battery transport unit 10A is released at the intermediate delivery position β2.

  On the other hand, since the three permanent magnets 26 are embedded at the intermediate delivery position β2 on the outer peripheral surface of the magnet wheel 25 of the downstream battery transport unit 20A, the upstream battery transport unit 10A at the intermediate delivery position β2. The dry battery C from which the suction and holding of the star wheel 13 is released is sucked and held in the fitting recess 23a of the star wheel 23 of the downstream battery transport unit 20A by the magnetic attraction force of the permanent magnet 26 embedded in the magnet wheel 25. Then, the dry battery C is transferred from the upstream battery transport unit 10A to the downstream battery transport unit 20A.

  Thus, the dry battery C delivered from the upstream battery transport unit 10A to the downstream battery transport unit 20A is sucked and held in the fitting recess 23a of the star wheel 23 of the downstream battery transport unit 20A. As the star wheel 23 rotates, the star wheel 23 is conveyed to the final delivery position β3.

  Only two permanent magnets 26 are embedded immediately before the last delivery position β3 on the outer peripheral surface of the magnet wheel 25 of the downstream battery transport unit 20A, and the label delivery device is placed at the last delivery position β3. 4 is overhanging, the magnetic attraction force decreases immediately before the last delivery position β3, and the dry battery with respect to the star wheel 23 of the downstream battery transport unit 20A at the last delivery position β3. While the suction holding of C is released, the dry battery C is sandwiched between the sticking drum 4a and the sticking guide 4b of the label sticking device 4, and the dry battery C is delivered from the downstream battery transport unit 20A to the label sticking device 4. .

  As shown in FIGS. 1 and 2, the battery carry-out device 6 is a dry battery C to which a label is attached from the label attaching device 4 at the first delivery position γ1 that is the end position of the label attaching section α in the attaching drum 4a. Battery transport unit 10B that receives the battery and transports it to the intermediate delivery position γ2, and downstream battery transport that receives the dry battery C from the upstream battery transport unit 10B and transports it to the final delivery position γ3 at the intermediate delivery position γ2. Unit 20B, and at the final delivery position γ3, the dry battery C is delivered from the downstream battery transport unit 20B to the battery transport conveyor 6a. For the upstream battery transport unit 10B, the first delivery position γ1 corresponds to the first delivery position of the present invention, the intermediate delivery position γ2 corresponds to the second delivery position of the present invention, and the downstream battery transport unit 20B. Therefore, the intermediate delivery position γ2 corresponds to the first delivery position of the present invention, and the last delivery position γ3 corresponds to the second delivery position of the present invention.

  The upstream battery transport unit 10B and the downstream battery transport unit 20B constituting the battery carry-out device 6 are also basically the same as the upstream battery transport unit 10A and the downstream battery transport unit 10B of the battery supply device 5 described above. Since it has the same structure, in FIGS. 9-12 which shows the battery carrying-out apparatus 6, the same code | symbol is attached | subjected to the same component, the description is abbreviate | omitted, and a different part is demonstrated. In addition, the code | symbol 6b in FIGS. 9-12 has shown the support plate which supports the rotational drive shafts 11 and 21. FIG.

  The magnet wheel 15 constituting the upstream battery transport unit 10B has a magnet in a region extending from the first delivery position γ1 on the outer peripheral surface to a position immediately before the intermediate delivery position γ2 in the rotation direction of the star wheel 13. Permanent magnets 16 and 26 are embedded in the wheel 25 in a region from an intermediate delivery position γ2 on the outer peripheral surface to a position immediately before the last delivery position γ3 in the rotation direction of the star wheel 23, respectively. The three permanent magnets 16 and 26 are arranged at the first delivery position γ1 at 15 and the middle delivery position γ2 at the magnet wheel 25, and the last position at the magnet wheel 25 and the last position at the middle delivery position γ2 in the magnet wheel 15 are arranged. Two permanent magnets 16 and 26 are arranged immediately before the delivery position γ3. As shown, the permanent magnets 16 and 26 are alternately arranged such as three, two, three, two, and so on.

  The magnet wheel 15 constituting the upstream battery transport unit 10B is partially formed with a recess 15a for receiving the other end of the sticking guide 4b in the label sticking device 4 before the first delivery position γ1. In the final delivery position γ3 on the outer peripheral surface of the magnet wheel 25 constituting the downstream battery transport unit 20B, the dry battery C is separated from the fitting recess 23a of the star wheel 23, and one end side is the outer periphery of the magnet wheel 15 A guide member 29 having a guide surface 29a that is flush with the surface is attached.

  In the battery carry-out device 6 configured as described above, the dry battery C with the label attached, which has been transported to the first delivery position γ1 that is the end position of the label application section α in the application drum 4a, is the upstream battery. At the same time as it fits in the fitting recess 13a of the star wheel 13 in the transport unit 10B, it is held by the magnetic attractive force of the permanent magnet 16 embedded in the magnet wheel 15, and in this state it is transported to the intermediate delivery position γ2, At the delivery position γ2, it is also fitted into the fitting recess 23a of the star wheel 23 in the downstream battery transport unit 20B.

  Only two permanent magnets 16 are embedded immediately before the intermediate delivery position γ2 on the outer peripheral surface of the magnet wheel 15 of the upstream battery transport unit 10B, and the permanent magnets are located at the intermediate delivery position γ2. Since it is not buried, the magnetic attractive force decreases immediately before the intermediate delivery position γ2, and the suction holding of the dry battery C with respect to the star wheel 13 of the upstream battery transport unit 10B is released at the intermediate delivery position γ2.

  On the other hand, since the three permanent magnets 26 are embedded at the intermediate delivery position γ2 on the outer peripheral surface of the magnet wheel 25 of the downstream battery transport unit 20B, the upstream battery transport unit 10A at the intermediate delivery position γ2. The dry battery C from which the suction and holding of the star wheel 13 is released is sucked and held in the fitting recess 23a of the star wheel 23 of the downstream battery transport unit 20B by the magnetic attractive force of the permanent magnet 26 embedded in the magnet wheel 25. Then, the dry battery C is transferred from the upstream battery transport unit 10B to the downstream battery transport unit 20B.

  Thus, the dry cell C delivered from the upstream battery transport unit 10B to the downstream battery transport unit 20B is sucked and held in the fitting recess 23a of the star wheel 23 of the downstream battery transport unit 20B. As the star wheel 23 rotates, it is transported to the final delivery position γ3.

  Only two permanent magnets 26 are embedded immediately before the last delivery position γ3 on the outer peripheral surface of the magnet wheel 25 of the downstream battery transport unit 20B, and the permanent magnet is placed at the last delivery position γ3. Since the guide member 29 is not embedded and the guide member 29 is attached, the magnetic attractive force decreases immediately before the last delivery position γ3, and the dry battery with respect to the star wheel 23 of the downstream battery transport unit 20B at the last delivery position γ3. The suction holding of C is released, and the dry battery C is separated from the fitting recess 23a of the star wheel 23 by the guide member 29, and the dry battery C is transferred from the downstream battery transfer unit 20B to the battery transfer conveyor 6a.

  As described above, the upstream battery transport units 10A and 10B and the downstream battery transport units 20A and 20B mounted on the battery supply device 5 and the battery carry-out device 6 position the dry battery C in the fitting recesses 13a and 23a. The star wheels 13 and 23 rotating in a state are separated from the fixedly installed magnet wheels 15 and 25 which hold the dry batteries C positioned by the star wheels 13 and 23 to the star wheels 13 and 23 by magnetic attraction. The magnet wheel 15 is located in the region from the first delivery position β1, γ1 on the outer peripheral surface to the position immediately before the intermediate delivery position β2, γ2, and the magnet wheel 25 is intermediate in the outer peripheral surface. In the region from the delivery position β2, γ2 to the position immediately before the last delivery position β3, γ3, the star wheels 13, 2 Since the permanent magnets 16 and 26 for attracting and holding the dry batteries C fitted in the three fitting recesses 13a and 23a to the star wheels 13 and 23 are embedded, the upstream battery transport units 10A and 10B and the downstream battery transport Intermediate delivery positions β2, γ2 for delivering the dry battery C between the units 20A, 20B, the last delivery position β3 for delivering the dry battery C between the downstream battery transport unit 20A and the labeling device 4 and the downstream battery At the final delivery position γ3 for delivering the dry battery C between the transport unit 20B and the battery transport conveyor 6a, the dry battery C is not sucked and held by the star wheels 13 and 23 to which the dry battery C is to be delivered. Unlike the transport unit, it is not necessary to forcibly separate the transported object from the star wheel by the guide member. Effects such as Tagged label is less susceptible to damage is obtained.

  In particular, in the upstream battery transport units 10A and 10B and the downstream battery transport units 20A and 20B, the magnet wheels 15 and 25 are embedded at positions just before the intermediate delivery positions β2 and γ2 or just before the last delivery positions β3 and γ3. The number of permanent magnets 16 and 26 to be reduced is reduced so that the magnetic attractive force is reduced from the position immediately before the intermediate delivery positions β2 and γ2 and the position immediately before the last delivery positions β3 and γ3. Delivery can be performed smoothly and reliably.

  In addition, when the dry battery C is transferred between the upstream battery transport units 10A and 10B and the downstream battery transport units 20A and 20B, the upstream transport unit and the downstream transport unit, as in the conventional transport unit, are used. Therefore, it is not necessary to make a difference in the magnetic attraction force for attracting and holding the object to be transported, so that the upstream battery transport units 10A and 10B can sufficiently secure the holding power of the dry cell C. At the same time, it is not necessary to manufacture two types of transport units having different magnetic attractive forces, and the transport units can be shared, so that the manufacturing cost of the transport units can be reduced.

  In the downstream battery transport unit 20B, a guide member 29 having a guide surface 29a for separating the dry battery C from the fitting recess 23a of the star wheel 23 is attached to the last delivery position γ3 on the outer peripheral surface of the magnet wheel 25. Therefore, the dry battery C can be reliably delivered in a stable state from the downstream battery transport unit 20B to the battery transport conveyor 6a having no magnetic attraction.

  In the above-described embodiment, the battery supply device 5 and the battery unloading device 6 that transport the dry battery C by combining two battery transport units, the upstream battery transport units 10A and 10B and the downstream battery transport units 20A and 20B, will be described. However, the present invention is not limited to this, and the dry battery C can be transported by one battery transport unit, or the dry battery C can be transported by combining three or more battery transport units.

  In the above-described embodiment, the number of permanent magnets 16 and 26 embedded in the position immediately before the intermediate delivery positions β2 and γ2 and the position immediately before the final delivery positions β3 and γ3 in the magnet wheels 15 and 25 is reduced. The magnetic attractive force is decreased from the position immediately before the intermediate delivery positions β2 and γ2 and the position immediately before the last delivery positions β3 and γ3, but the present invention is not limited to this, and the intermediate delivery positions β2, γ2 The magnetic attraction force may be decreased step by step from a position just before the last position or just before the last delivery position β3, γ3.

  In the above-described embodiment, the permanent magnets 16 and 26 are embedded in the magnet wheels 15 and 25. However, the present invention is not limited to this, and an electromagnet can be embedded. When the permanent magnets 16 and 26 are embedded in the magnet wheels 15 and 25, the permanent magnets 16 and 26 are attached to the outer peripheral surfaces of the magnet wheels 15 and 25 using an adhesive tape having an adhesive force stronger than the magnetic attractive force of the permanent magnets 16 and 26. The magnetic material must be removed, but in the case of an electromagnet, by stopping energization, the magnetic attractive force can be removed and cleaning can be performed, so that workability is good.

  In addition, when an electromagnet is employed, the magnetic attraction force of the magnet wheel can be set freely as a whole, and the magnetic attraction force of the magnet wheel can be set partially freely. This is effective when the magnetic attractive force is reduced step by step slightly before the position just before the delivery position. Furthermore, since the area | region which provides the magnetic attraction force in the outer peripheral surface of a magnet wheel can also be set freely, the effect that it can respond easily when a delivery position is changed is acquired.

  The transport unit of the present invention can be applied not only to dry batteries but also to transport various transported objects attracted by a magnet such as a steel can.
