Description

  The present invention relates to a technique for supplying parts such as rubber stoppers.

  Patent Document 1 discloses a rubber plug insertion device that inserts an electric wire into a rubber plug in a cutting pressure facility.

  In this rubber plug insertion device, one rubber plug is pumped by air from the rubber plug supply pipe to the one end side opening of the through hole through the rubber plug supply hole and the middle part of the through hole. The rubber plug is held in the rubber plug housing recess of the plug holding member. Then, the pin member is moved forward (one end side of the through-hole portion), and the tip end portion of the core pin main body portion is press-fitted into the internal hole of the rubber plug in the rubber plug housing recess. In this state, the electric wire is inserted from the front (electric wire holding member side).

  The rubber plug inserted into the electric wire is formed in a cylindrical shape as a whole. When transporting such a rubber plug to the rubber plug insertion device, it is necessary to transport the rubber plug with the same posture. For this reason, when conveying to a rubber plug insertion device, a vibration type part feeder having a vibration mechanism for aligning the posture of the rubber plug by vibration is used.

  However, in the case of the rubber plug insertion device, it is necessary to prepare one vibration part feeder for each cutting pressure equipment. For this reason, when rubber plug insertion is performed in a plurality of rubber plug insertion devices, the same number of vibratory parts feeders as the number of rubber plug insertion devices is required. Then, since the vibration type parts feeder is expensive, the equipment cost of the rubber plug insertion device becomes high.

  On the other hand, Patent Document 2 discloses a cartridge-type parts feeder that is configured by winding a tube member that can be filled with a plurality of rubber stoppers aligned in a posture. In this cartridge-type parts feeder, rubber plugs are supplied by air pressure connection to each rubber plug insertion device. Since this cartridge-type parts feeder can be prepared at a lower cost than the vibration-type parts feeder, the equipment cost of the rubber plug insertion device can be reduced.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. In addition, the component described in this embodiment is an illustration to the last, and is not a thing of the meaning which limits the scope of the present invention only to them. In the drawings, the size and number of each part may be exaggerated or simplified as necessary for easy understanding.

<1. First Embodiment>
FIG. 1 is a block diagram showing the connection between a cartridge-type parts feeder 1 and a parts transfer device 100 according to the embodiment. FIG. 2 is a schematic side view of the cartridge-type parts feeder 1 according to the embodiment.

<Configuration of cartridge type parts feeder>
The cartridge-type parts feeder (hereinafter simply referred to as a parts feeder) 1 has portability, and a plurality of parts having the same shape and the same size are arranged in a line in the same posture. The tube member 40 filled with is provided. In the present embodiment, it is assumed that the rubber member 50 into which the electric wire is inserted is filled in the tube member 40 as a part.

  The parts feeder 1 is connected to a parts transfer device 100 described later, and supplies the rubber plugs 50 to the parts transfer device 100 while maintaining their postures constant. The parts transfer device 100 separates the plurality of rubber plugs 50 supplied from the parts feeder 1 one by one and transfers them to the cutting machine 900. Although the detailed illustration is omitted, the cutting machine 900 includes a wire insertion device. The electric wire insertion device inserts the electric wire that has been subjected to processing such as cutting and terminal crimping by the cutting machine 900 into the rubber plug 50 transferred from the parts transfer device 100.

  As shown in FIG. 2, the parts feeder 1 includes a transparent tube member 40 (tubular body), a male coupler member 43 (part entry / exit portion) connected to one end of the tube member 40, and the other end of the tube member 40. An air hose 45 (tubular body) connected to a part via a coupler member (gas inlet / outlet part) (not shown), a male coupler member 48 connected to the other end of the air hose 45, a tube member 40 and an air hose 45 are wound. And a cartridge 31 that is rotated and held. The internal passage formed in the tube member 40 is an example of a parts filling path 400 that can be filled in a state in which the plurality of rubber stoppers 50 are aligned in a line. The tube member 40, the air hose 45, the male coupler member 43, and the male coupler member 48 are examples of parts supply members.

  The cartridge 31 has a pair of plate members 32 formed in a rectangular shape, and a winding shaft portion 34 for winding the tube member 40 and the air hose 45. The pair of plate members 32 are arranged in parallel so as to face each other in the depth direction of the paper surface, and a winding shaft portion 34 is fixed between the pair of plate members 32 at the central portion of the pair of plate members 32.

  A guide member 35 is attached and fixed to the inner surface side of the central portion in the front-rear direction at the upper end portion of the plate member 32. An insertion hole is formed in the guide member 35, and the guide member 35 guides the tube member 40 in the winding direction by inserting the tube member 40 through the insertion hole. Guide members 37 and 38 are fixedly mounted in the vertical direction on the inner surface side of the rear end portion in the central portion in the vertical direction of the plate member 32. Insertion holes are formed in the guide members 37, 38, and the guide members 37, 38 guide the tube member 40 through the insertion holes in the winding direction. As a configuration for mounting and fixing the guide members 35, 37, and 38, a plurality of screws 53 are used here, but the configuration for mounting and fixing is not particularly limited.

<Configuration of tube member and air hose>
Next, the tube member 40 and the air hose 45 will be described. The tube member 40 and the air hose 45 are formed in a state of being wound around the winding shaft portion 34. The tube member 40 is formed to have an inner diameter corresponding to the outer diameter of the rubber plug 50. In other words, the tube member 40 has an inner diameter larger than the maximum outer diameter of the rubber plug 50 so that a plurality of rubber plugs 50 can be filled and can maintain a constant posture, and is more than the projected shape from the side of the rubber plug 50. Is also formed to have a small inner diameter. Further, a male coupler member 43 of the coupler member 41 is connected to one end of the tube member 40, and the inner diameter of the male coupler member 43 can be filled with a plurality of rubber stoppers 50 and can maintain a constant posture. The inner diameter is larger than the outer diameter of the rubber plug 50 and is smaller than the projected shape from the side of the rubber plug 50. For this reason, the tube member 40 (including the opening 40a at one end) and the male coupler member 43 can pass through the plurality of rubber plugs 50 while maintaining their postures constant. The opening 40 a at one end of the tube member 40 corresponds to the opening on one side of the parts filling path 400.

  The tube member 40 has flexibility and is formed in a predetermined length. In the present embodiment, the tube member 40 is formed to a length that can be filled with, for example, about 1000 rubber plugs 50. Of course, the tube member 40 may have various lengths depending on the number of the rubber plugs 50 to be filled. The tube member 40 is not necessarily wound and the tube member 40 is short. May be held in a substantially straight line. In addition, the parts supply member may be configured by general piping or the like, and in this case, may be formed in various shapes such as a wound shape or a straight shape. Further, as the parts supplied by the parts feeder 1, a plurality of types of rubber plugs are usually assumed. The plurality of types of rubber plugs are different in length, outer diameter, outer shape, and the like. In this case, various tube members having an inner diameter corresponding to the length, outer diameter, outer shape, etc. of the rubber plug can be applied. In addition to rubber plugs, the parts may be other electric parts (terminals, etc.), various parts and members for automobiles, medicines, foods, and the like.

  One end of an air hose 45 having an inner diameter smaller than the outer diameter of the rubber plug 50 is connected to the other end of the tube member 40 via a coupler member. The air hose 45 is flexible, and a male coupler member 48 of the coupler member 46 is connected to the other end of the air hose 45, and a coupler member connected to the other end of the tube member 40 and a male coupler are connected. The member 48 has an inner diameter that is smaller than the outer diameter of the rubber plug 50. For this reason, the coupler member connected to the other end of the tube member 40, the air hose 45, and the male coupler member 48 are configured to be able to flow in and out of pressure-feeding air (gas). It is configured not to pass.

  As shown in FIG. 1, when the rubber plug 50 is conveyed to the cutting machine 900, the air hose 45 and the air supply source 82 of the parts feeder 1 are connected via the coupler member 46 and the tube member 40 of the parts feeder 1. Are connected to each other via the tube member 44 and the coupler member 41. In the state where the pressure feed air supplied from the air supply source 82 flows into the tube member 40 from the male coupler member 48 via the air hose 45, and the plurality of rubber plugs 50 fed by the pressure feed air are aligned. It flows out of the male coupler member 43 through the tube member 40.

<Configuration of parts transfer device>
FIG. 3 is a schematic plan view of the parts transfer apparatus 100 according to the embodiment. FIG. 4 is a schematic side view of the parts transfer apparatus 100 according to the embodiment. In FIG. 4, for convenience of explanation, the parts transfer unit 110 is shown in a longitudinal sectional view when cut along the parts transfer path 116. FIG. 5 is an enlarged schematic plan view showing the distal ends of the movement restricting member 120, the first pressing member 130 and the second pressing member 140.

  Here, the rubber plug 50 according to the present embodiment has a structure in which a narrow part 51 having a narrow width and a wide part 52 wider than the narrow part 51 are connected along the central axis Q. (See FIG. 5). In addition, the inside of the wide portion 52 is assumed to have a recess having a size that allows the tip of the narrow portion 51 to enter. As shown in FIG. 2, the rubber plugs 50 having such a shape are arranged so that the central axes Q are aligned in a straight line in the parts filling path 400 of the tube member 40. 50 may be mutually connected. In this way, the parts transfer device 100 separates the rubber plugs 50 that are connected by being aligned in a row in this manner, and supplies them to devices such as the cutting machine 900.

  The parts transfer device 100 includes a parts transfer unit 110, a movement restricting member 120, a first pressing member 130, a second pressing member 140, and a pressure feeding unit 150.

  The parts transfer unit 110 includes a base 112 and a lid 114.

  The base 112 has a rectangular parallelepiped shape extending in the direction D1, and is a member formed of resin or metal. A groove 1121 extending along the direction D1 is formed on the upper surface of the central portion in the width direction of the base portion 112 (direction D2 orthogonal to the direction D1).

  The lid portion 114 is a plate-like member that covers the upper surface of the base portion 112. Here, the lid 114 is formed of a transparent material (for example, resin, glass, etc.), and the inside of the groove 1121 can be visually recognized through the lid 114 from above. It is said that. In addition, it is not essential to form the cover part 114 with a transparent material.

  The upper part of the groove 1121 of the base part 112 is closed by the lid part 114, so that a parts transfer path 116 is formed. The parts transfer path 116 extends in the direction D1 and has a circular cross section. In addition, the cross-sectional shape of the parts transfer path 116 is not limited to a circular shape, and may be another shape (for example, an elliptical shape, a semicircular shape, a polygonal shape, or the like). A tube member 44 connected to the parts filling path 400 is inserted on one side of the parts transfer path 116. A tube member 83 connected to the cutting machine 900 is inserted on the other side of the parts transfer path 116.

  In the following description, in the parts transfer path 126, the side where the rubber plug 50 enters (one side where the tube member 44 is inserted) is the inlet side, and the side where the rubber plug 50 exits (the tube member 83 is inserted). The exit side).

  The rubber stopper 50 is movable in the middle part of the parts transfer path 116 so that the central axis Q is parallel to the direction D1. Specifically, the inner diameter (vertical and horizontal width) of the intermediate portion of the parts transfer path 116 has an inner diameter larger than the maximum outer diameter W1 of the rubber plug 50 and is smaller than the height H1 of the rubber plug 50. For this reason, in the intermediate part of the parts transfer path 116, it is suppressed that the rubber stopper 50 becomes the standing posture (the posture in which the central axis Q is orthogonal to the directions D1 and D2).

  The inner diameters of the one side portion and the other side portion of the parts transfer path 116 are substantially the same as the outer diameters of the tube member 44 and the tube member 83 inserted therein. Further, the inner diameter of the intermediate portion of the parts transfer path 116 is substantially the same as the inner diameter of each of the tube members 44 and 83. For this reason, the rubber stopper 50 passes through the inlet side tube member 44 and the middle part of the parts transfer path 116, and can smoothly move the outlet side tube member 83 without being caught. That is, the rubber plug 50 can pass through the parts transfer path 116 while maintaining a falling posture (a posture in which the central axis Q is parallel to the direction D1).

  It should be noted that the rubber plug 50 may be more smoothly transferred from the tube member 44 to the parts transfer path 116 by making the inner diameter of the intermediate portion of the parts transfer path 116 larger than the inner diameter of the tube member 44. Further, by making the inner diameter of the intermediate portion of the parts transfer path 116 smaller than the inner diameter of the tube member 83, the rubber plug 50 may be more smoothly transferred from the parts transfer path 116 to the tube member 83.

  The movement restricting member 120 is a rod-shaped member having a rounded tip, and is provided so as to be movable in a crossing direction (here, direction D2) intersecting the parts transfer path 116 by the movement restricting member driving unit 121. The movement restricting member 120 protrudes to the inside of the parts transfer path 116, so that the rubber plug 50 (the first rubber plug 50a closest to the outlet side, which is closest to the outlet side) among the plurality of rubber plugs 50 corresponds to the first part. .) Is restricted.

  The movement restricting member driving unit 121 is configured by, for example, an air cylinder that uses air supplied from an air supply source 82 as a driving source. However, it is not essential that the movement restricting member driving unit 121 is composed of an air cylinder, and it may be composed of another mechanism (such as a hydraulic cylinder or a motor driving mechanism).

  The movement restricting member 120 is provided so as to penetrate the parts transfer unit 110 from one side in the direction D2 toward the other side. The movement restricting member 120 is disposed so as to protrude inward at an intermediate portion of the parts transfer path 116. Specifically, the movement restriction member 120 is moved between the restriction position L11 and the restriction release position L12 outside the part transfer path 116 with respect to the restriction position L11 by the movement restriction member driving unit 121 as shown in FIG. Moving.

  Note that the movement restricting member driving unit 121 can be omitted by configuring the movement restricting member 120 to be moved manually. However, providing the movement restricting member driving unit 141 can reduce the burden on the operator.

  The restriction position L11 is a position where the tip of the movement restriction member 120 is disposed on the other side in the direction D2 from the center of the part transfer path 116. However, the restriction position L11 is not necessarily limited to this position. For example, the restriction position may be a position where the distal end portion of the movement restriction member 120 is arranged on one side in the direction D2 without exceeding the center of the part transfer path 116. In other words, if the gap between the tip of the movement restricting member 120 arranged at the restricting position L11 and the parts transfer path 116 is at least smaller than the maximum outer diameter W1 of the rubber plug 50, the movement of the rubber plug 50 is restricted. .

  The restriction release position L <b> 12 is a position where the tip of the movement restricting member 120 moves away from the part transfer path 116. The restriction release position L12 may be a position where the tip of the movement restricting member 120 is disposed inside the parts transfer path 116. If the gap between the movement restricting member 120 arranged at the restriction release position L12 and the parts transfer path 116 is at least larger than the maximum outer diameter of the rubber plug 50, the rubber plug 50 is movable.

  The first pressing member 130 and the second pressing member 140 are rod-shaped members with rounded tips, and intersecting directions intersecting the parts transfer path 116 by the first pressing member driving unit 131 and the second pressing member driving unit 141 ( Here, it is provided to be movable in the direction D2). The first pressing member 130 and the second pressing member 140 are the second rubber plug 50 arranged next to the first first rubber plug 50a (the second rubber plug arranged adjacent to the inlet side with respect to the first rubber plug 50a). 50b, corresponding to the second part) in the direction D2.

  The 1st press member drive part 131 and the 2nd press member drive part 141 are comprised by the air cylinder which uses the air supplied from the air supply source 82 as a drive source, for example. However, it is not essential that the movement restricting member driving unit 121 is composed of an air cylinder, and it may be composed of another mechanism (such as a hydraulic cylinder or a motor driving mechanism).

  Further, the first pressing member driving unit 131 and the second pressing member driving unit 141 can be omitted by configuring the first pressing member 130 and the second pressing member 140 to be manually moved. However, by providing the first pressing member driving unit 131 and the second pressing member driving unit 141, the burden on the operator can be reduced.

  The first pressing member 130 is provided so as to penetrate the parts transfer unit 110 from the other side in the direction D2 toward the one side. The 1st press member 130 is distribute | arranged to the entrance side rather than the movement control member 120, and the wide part 52 of the 2nd rubber plug 50b is pressed in the front-end | tip part. Accordingly, the second rubber plug 50b is pressed against the inner peripheral surface of the parts transfer path 116, and the movement of the second rubber plug 50b is suppressed.

  The first pressing member driving unit 131 is configured to place the first pressing member 130 between a pressing position L21 that presses the second rubber stopper 50b and a pressing release position L22 that is radially outward of the parts transfer path 116 from the pressing position L21. Move with. When the first pressing member 130 is disposed at the pressing position L <b> 21, the leading end portion of the first pressing member 130 protrudes inside the parts transfer path 116. Further, when the first pressing member 130 is disposed at the pressing release position L <b> 22, the leading end portion of the first pressing member 130 is retracted from the parts transfer path 116. The pressing release position L22 may be a position where the pressing of the second rubber plug 50b is released. For this reason, the front-end | tip part of the 1st press member 130 does not need to retract completely from the parts transfer path 116. FIG.

  As shown in FIG. 5, the distance L1 from the outlet side end of the movement restricting member 120 to the central axis of the first pressing member 130 is larger than the height H1 of the first rubber plug 50a. That is, in the state where the movement of the first rubber plug 50a is restricted by the movement restricting member 120, the center of the second pressing member 140 is arranged at a position closer to the inlet side than the first rubber plug 50a. For this reason, the front-end | tip part of the 2nd press member 140 presses the wide part 52 of the 2nd rubber stopper 50b. At this time, although the wide portion 52 of the second rubber plug 50b into which the narrow portion 51 of the first rubber plug 50a is inserted is pressed, the pressing force is suppressed from acting on the first rubber plug 50a. The That is, the second rubber stopper 50b can be selectively pressed.

  The second pressing member 140 is provided so as to penetrate the parts transfer unit 110 from one side in the direction D2 toward the other side. The second pressing member 140 is disposed closer to the inlet side than the first pressing member 130 and presses the wide portion 52 of the second rubber plug 50b at the tip portion thereof. As a result, the second rubber plug 50b is pressed against the inner peripheral surface of the parts transfer path 116 to limit the movement of the second rubber plug 50b.

  The second pressing member drive unit 141 is configured to place the second pressing member 140 between a pressing position L31 that presses the second rubber stopper 50b and a pressing release position L32 that is radially outward of the parts transfer path 116 from the pressing position L31. Move with. When the second pressing member 140 is disposed at the pressing position L <b> 31, the distal end portion of the second pressing member 140 is in a state of protruding to the inside of the parts transfer path 116. Further, when the second pressing member 140 is disposed at the pressing release position L <b> 32, the distal end portion of the second pressing member 140 is retracted from the part transfer path 116. The pressing release position L32 may be a position where the pressing of the second rubber plug 50b is released. For this reason, the front-end | tip part of the 1st press member 130 does not need to retract completely from the parts transfer path 116. FIG.

  As shown in FIG. 5, the central axis of the second pressing member 140 is disposed so as to overlap the narrow portion 51 of the second rubber plug 50b to which the first rubber plug 50a is connected in the direction D1. As shown in FIG. 5, even if the narrow portion 51 of the second rubber plug 50 b enters the wide portion 52 of the adjacent rubber plug 50, the second pressing member 140 is not connected to the adjacent rubber plug 50. The second rubber stopper 50b can be pressed via

  When the first pressing member 130 and the second pressing portion 140 press different positions in the direction D1, the second rubber plug 50b can be bent and deformed. As a result, the first rubber plug 50a having the tip portion that has entered the second rubber plug 50b can be easily removed. Therefore, it becomes easy to separate the first rubber plug 50a from the second rubber plug 50b.

  Note that it is not essential to press the rubber stopper 50 against the inner peripheral surface of the parts transfer path 116 by the first pressing member 130 and the second pressing member 140. That is, the second rubber stopper 50b may be sandwiched between the first pressing member 130 and the second pressing member 140.

  The pressure feeding unit 150 supplies air sent from the air supply source 82 to the parts transfer path 116 and transfers the first part to the outlet side of the parts transfer path 116. Here, the pressure feeding unit 150 includes a nozzle 151 penetrating the lid part 114 and having a tip part inserted into the part transfer path 116. The tip portion of the nozzle 151 is directed to the combined direction of the direction toward the center of the parts transfer path 116 (inward in the radial direction) and the direction toward the outlet side in the direction D1. The pressure feeding unit 150 blows air to the boundary portion between the wide portion 52 and the narrow portion 51 of the first rubber plug 50 a positioned by the movement restricting member 120. In this state, the movement restricting member 120 moves to the restriction release position L12, whereby the first rubber plug 50a is transferred to the outlet side. At this time, only the first rubber plug 50a is separated from the second rubber plug 50b and transferred by pressing the second rubber plug 50b with the first pressing member 130 and the second pressing member 140.

  The controller 160 controls operations of the movement restricting member driving unit 121, the first pressing member driving unit 131, the second pressing member driving unit 141, and the pressure feeding unit 150. The hardware configuration of the control unit 160 is the same as that of a general computer. That is, the control unit stores a CPU that performs various arithmetic processes, a ROM that is a read-only memory that stores basic programs, a RAM that is a readable and writable memory that stores various information, and a control application or data. A storage unit is provided.

<Flow of parts transfer work>
FIG. 6 is a diagram illustrating a flow of parts transfer work using the parts transfer apparatus 100 according to the embodiment. When parts are transferred using the parts transfer device 100, as shown in FIGS. 1 and 3, the tube member 44 is inserted on the inlet side of the parts transfer path 116, and the tube member 83 is inserted on the outlet side. As a result, the inlet side of the parts transfer path 116 is connected to the parts feeder 1 (specifically, the parts filling path 400), and the outlet side is connected to the cutting machine 900 (step S1).

  Subsequently, the control unit 160 moves the movement restricting member 120 to the restricting position L11 by operating the movement restricting member driving unit 121 (step S2). If the movement restricting member 120 is already arranged at the restricting position L11, step S2 is skipped.

  Subsequently, the control unit 160 operates the first pressing member driving unit 131 and the second pressing member driving unit 141 to move the first pressing member 130 and the second pressing member 140 to the press release positions L22 and L32. (Step S3). When the first pressing member 130 and the second pressing member 140 are already arranged at the pressing release positions L22 and L32, step S3 is skipped.

  Subsequently, air supply is started from the air supply source 82 (step S4). Thereby, the plurality of rubber plugs 50 filled in the tube member 40 of the parts feeder 1 move to the parts transfer path 116 of the parts transfer device 100. Then, the rubber plug 50 (first rubber plug 50a) arranged at the head comes into contact with the movement restricting member 120 at the restricting position L11 and is positioned. Moreover, the movement of each rubber plug 50 arranged next to the first rubber plug 50a is also suppressed.

  Further, in step S4, upon receiving the air supply from the air supply source 82, the pressure feeding unit 150 also starts supplying air. In addition, it is not essential that the pumping unit 150 always supplies air. For example, the pressure feeding unit 150 may perform air supply and air supply stop based on the control of the control unit 160.

  Subsequently, the control unit 160 moves the first pressing member 130 and the second pressing member 140 to the pressing positions L21 and L31 by operating the first pressing member driving unit 131 and the second pressing member driving unit 141, respectively. (Step S5). Accordingly, the position of the second rubber plug 50b is fixed by being pressed.

  Subsequently, the control unit 160 moves the movement restriction member 120 to the restriction release position L12 by operating the movement restriction member driving unit 121 (step S6). As a result, the movement restricting member 120 disposed in front of the first rubber plug 50a is retracted. Then, the air supplied from the nozzle 151 of the pressure feeding unit 150 is blown to the first rubber plug 50a, whereby the first rubber plug 50a is transferred to the outlet side.

  Subsequently, the control unit 160 moves the movement restricting member 120 to the restricting position L11 by operating the movement restricting member driving unit 121 (step S7). Moreover, the control part 160 moves the 1st press member 130 and the 2nd press member 140 to the press release position L22, L32 by operating the 1st press member drive part 131 and the 2nd press member drive part 141 ( Step S8). As a result, the remaining rubber plug 50 is pumped forward by the air from the air supply source 82 and advances forward, and the rubber plug 50 (second rubber plug 50b) arranged at the head comes into contact with the movement restricting member 120, and the movement is continued. It is suppressed.

  Thereafter, step S5 to step S8 are repeatedly performed. By performing steps S5 to S8 for one cycle, one rubber plug 50 is transferred from the parts transfer device 100 to the cutting machine 900.

  Thus, according to the parts transfer device 100 according to the present embodiment, the leading rubber plug 50 is stopped by the movement restricting member 120 at the restricting position L11 (steps S7 and S8), and the second rubber plug 50 is in the meantime. However, the first pressing member 130 and the second pressing member 140 are gripped (step S5). Further, when the movement restricting member 120 is retracted, the leading rubber plug 50 is separated from the second rubber plug 50 and pumped (step S6). Thus, even if the parts transfer device 100 is the rubber plug 50 which has a shape connected mutually, it can be separated one by one and can be supplied to devices, such as a cutting pressure machine 900.

<Modification>
In the above embodiment, the first pressing member 130 and the second pressing member 140 are configured to press the second rubber stopper 50 at different positions in the direction D1. However, the first pressing member 130 and the second pressing member 140 may press the second rubber plug 50 at the same position in the direction D1. Moreover, in the said embodiment, although the 1st press member 130 and the 2nd press member 140 press the 2nd rubber stopper 50 from a different side, you may make it press from the same side. Further, it is possible to omit either the first pressing member 130 or the second pressing member 140.

  Moreover, in the said embodiment, as shown in FIG. 1, the several rubber stopper 50 is moved to the parts transfer apparatus 100 by supplying air to the parts feeder 1 from the air supply source 82. As shown in FIG. However, the plurality of rubber stoppers 50 may be moved from the parts feeder 1 to the parts transfer device 100 by performing air suction from the cutting machine 900 side. Further, the tube member 40 of the rubber plug 50 may be arranged at a position higher than the parts transfer device 100, and the plurality of rubber plugs 50 may be moved to the parts transfer device 100 by gravity.

  Although the present invention has been described in detail, the above description is illustrative in all aspects, and the present invention is not limited thereto. It is understood that countless variations that are not illustrated can be envisaged without departing from the scope of the present invention. In addition, the configurations described in the above embodiments and modifications can be appropriately combined or omitted as long as they do not contradict each other.
