[0002]

[Prior art]

 In the conventional supply device of this type, when a cylindrical part 1 having a shape as shown in FIG. 5 is set, the set part 2 is passed through the cylindrical part 1 through a set jig 2 made of a long round bar. The jig 2 holds a plurality of cylindrical parts 1. Then, the set jig 2 is laid down so that the cylindrical part 1 does not slip off from the set jig 2, and in that state, it is carried to the position of the magazine 3. When carried to the magazine 3, as shown in FIG. 6, the setting jig 2 is inserted into the magazine 3 in a state in which the cylindrical component 1 is tilted so as not to slide down. In that case, the cylindrical part 1 is inserted into the magazine 3 while pressing the cylindrical part 1 against the inner wall of the magazine 3 so as not to drop the cylindrical part 1 at the bottom through which the setting jig 2 is inserted. It is set to be stacked inside. When the cylindrical component 1 is set in the magazine 3, in order to prevent the cylindrical component 1 from slipping down from the setting jig 2, a hooking portion (at which the cylindrical component 1 can be hooked to the tip of the setting jig 3 ( A device provided with (not shown) may be used. Then, when the cylindrical part 1 is set in the magazine 3 by the setting jig 2, the cylindrical part 1 is sequentially opened from the lower discharge part of the magazine 3 every time the shutter 5 provided on the index table 4 is opened and closed. I am trying to supply it.

[Problems to be solved by the device]

 By the way, in the prior art shown above, when the setting jig 2 is simply a long round bar, when the cylindrical part 1 passed through this is carried to set in the magazine 3, the cylindrical part 1 falls. The set jig 2 must be carried while lying down so that it does not come into contact, and when inserting the set jig 2 into the magazine 3, it must be tilted in the magazine 3 so that the cylindrical part 1 does not accidentally slip off. However, if the setting jig 2 is not properly tilted during insertion, the cylindrical part 1 will slide down from the setting jig 2 as shown in FIG. , There was a problem that the usability was very poor. On the other hand, when using the set jig 2 having a hooking portion at the tip, it is easy to move the cylindrical part 1 while holding it, but the set jig holding the cylindrical part 1 is easy to move. When inserting 2 into the magazine 3, it is necessary to pull out the cylindrical component 1 from the setting jig 2 by shaking the setting jig 2 in the magazine 3, so pulling out the cylindrical component 1 from the setting jig 2 There was a problem that could not be easily.

In view of the above-mentioned circumstances, an object of the present invention is to provide a cylindrical component supply device that facilitates carrying of the cylindrical component and setting of the cylindrical component with respect to the magazine, thereby improving the usability of the setting jig. To do.

[0005]

[Means for Solving the Problems]

 In the device of the present invention, a fall-prevention plate formed so as to be openable and closable around the fulcrum of the tip is attached to the tip of the setting jig. The drop-out prevention plate expands to a size that can hold the cylindrical part that has been inserted through the set jig, closes to a width smaller than the inner diameter of the cylindrical part and the hole size provided in the shutter, and expands each other. In this state, when it is inserted into either the hole of the cylindrical part or the hole provided in the magazine shutter, it is configured to close around the fulcrum.

[0006]

[Action]

 When setting the cylindrical parts in the magazine, first close the fall prevention plate of the setting jig, pass the cylindrical parts through in this state, expand the fall prevention plate, and put the expanded fall prevention plate down. Carry the cylindrical parts to the magazine position. As a result, since the fall prevention plate is opened and the width dimension thereof is larger than the inner diameter dimension of the cylindrical component, the cylindrical component can be carried while the set jig is suspended straight. ◆ Then, insert the set jig into the magazine and push the fulcrum of the fall prevention plate into the hole (hole of the shutter) of the cylindrical part that is set in advance in the magazine to insert it. It gradually closes depending on the size, and the closed width dimension is smaller than the inner diameter dimension of the cylindrical part and the hole size of the shutter, so the cylindrical parts will slide down from the set jig in the magazine and will be sequentially stacked in the magazine. . After that, pull out the set jig from the magazine. In this case, since the fall prevention plate is closed as described above, the setting jig can be easily pulled out from the magazine.

[0007]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS. 1 to 4, the same reference numerals as those in FIGS. 5 and 6 represent the same or corresponding ones. In the feeder of the embodiment, a plurality of cylindrical parts 1 for forming a bearing are held by the set jig 2, and the set jigs 2 held are inserted into the magazine 3 as shown in FIG. The cylindrical parts 1 are set in a stacked state. When the cylindrical component 1 is set in the magazine 3, the shutter 5 of the index table 4 moves as shown by the arrow in FIG. 4 so that the cylindrical component 1 is sequentially supplied from the magazine 3 to desired positions. The setting jig 2 is composed of a long round bar. The magazine 3 is attached to the index table 4 via the separating part 6, and the cylindrical part 1 is inserted through the insertion port 3a provided in the upper part and the cylindrical part 1 is discharged through the discharging part 3b provided in the lower part. It is shaped like a cylinder so that The shutter 5 is arranged in the ejection portion 3b of the magazine 3.

In the present invention, a fall prevention plate 7 formed to be openable and closable is attached to the tip of the setting jig 2. As shown in FIG. 1, the fall prevention plate 7 is composed of two laterally symmetrical plates 71 and 72. These tip portions 71a and 72a are attached to the tip portion of the set jig 2 by a fulcrum pin 8. The other ends 71b and 72b are attached to each other so as to be able to spread around the fulcrum pin 8. In this case, when the two plates 71 and 72 are expanded, the width dimension L1 between the other ends 71b, 72b of the two plates 71 and 72 is made larger than the inner diameter dimension L2 of the cylindrical component 1 and the outer diameter of the cylindrical component 1 is increased. The size is made smaller so that the cylindrical part 1 having the setting jig 2 inserted therein can be held. When closed, the two plates substantially overlap each other as shown in FIG. 3, and the width dimension L3 between the other ends of the plates is determined from the inner diameter dimension L2 of the cylindrical part 1 and the dimension of the hole 5A formed in the shutter 5. The size is made smaller so that the holes 1A and 5A can be inserted in the closed state. Therefore, the stop pin 9 is projected on one plate 71, the guide hole 10 through which the pin 9 is inserted is formed on the other plate 72, and the pin 9 moves within the range of the guide hole 10 so that both plates 71 are moved. The opening / closing range of 72 is regulated.

Further, when the two plates 71 and 72 are in an expanded state, when they are inserted by being pushed into the hole 5A of the shutter 5 in the magazine 3 or the hole 1A of the cylindrical component 1 in the magazine 3, The other end portions 71b and 72b are closed by a peripheral portion forming a hole according to the insertion depth. Therefore, the fulcrum portion which is the tip of the two plates 71 and 72 can be easily inserted into the hole 5A of the shutter 5 and the hole 1A of the cylindrical component 1, and the plates 71 and 72 can be closed as they are inserted. It is formed in the shape of an arc.

When the cylindrical component 1 is set in the magazine 3 using such a setting jig 2, first, the fall prevention plate 7 of the setting jig 2 is closed, and in this state, a plurality of cylindrical components 1 are passed through, The two plates 71 and 72 of the fall prevention plate 7 are expanded, and the expanded fall prevention plate 7 is turned down to carry the cylindrical component 1 to the position of the magazine 3. As a result, since the other end portions 71b, 72b of the two plates 71, 72 of the fall prevention plate 7 are opened and the width dimension L 1 thereof is larger than the inner diameter dimension L2 of the cylindrical component 1, the setting jig 2 is It is possible to carry the cylindrical component 1 while hanging it straight. When the set jig 2 holds the cylindrical component 1, the fall prevention plate 7 may be opened in advance and held from the upper end of the set jig 2 through the cylindrical component 1.

Then, when the set jig 2 is put into the magazine 3 and the fulcrum portion of the fall prevention plate 7 is pushed into the hole 1A of the cylindrical part 1 which is preset in the magazine 3 as shown in FIG. Or, as shown in FIG. 3, when it is inserted into the hole 5A of the shutter 5 through the magazine 3, it is closed next according to the depth into which the two plates 71 and 72 of the fall prevention plate 7 are inserted, and Since the closed width dimension is smaller than the inner diameter dimension L2 of the cylindrical component 1, the cylindrical components 1 slide down from the setting jig 2 in the magazine 3 and are sequentially stacked in the magazine 3. ◆ After that, pull out the set jig 2 from the magazine 3. In this case, since the fall prevention plate 7 is closed as described above, the setting jig 2 can be easily pulled out from the magazine 3.

Further, in the illustrated embodiment, since the fulcrum portion which is the tip of the fall prevention plate 7 is formed in an arc shape, the fall prevention plate 7 is formed into the hole 1 A of the cylindrical part 1 in the magazine 3 or the hole of the shutter 5. When inserted in 5A, it can be easily inserted, and there is no risk that the fall prevention plate 7 will be caught in the holes 1A, 5A.
