It has become. The conveyor 41 includes a conveyor belt 45 including a plurality of shark-tooth-shaped conveyor plates 45 a having variable inclination, and a rotating machine 46 that rotates the conveyor belt 45. Each conveyor plate 45a is in a state of standing in the moving direction at a portion that moves linearly. Therefore, when the cold plastic working material 11 is on the conveyor belt 45, the conveyor plate 45a is cooled. The interplastic working material 11 and each conveyor plate 45a are in point contact, and their contact area is minimized. The rotating machine 46 is provided with an air nozzle 47 that blows air toward the cold plastic working material 11 on the conveyor belt 45.

Next, the operation of the lubricant application device according to the embodiment of the present invention will be described.
As shown in FIG. 2, some of the cold plastic working materials 11 housed in the stocker 7 are on the upper end portion 14 a when the hopper 14 rises along the inner surface 7 a. Lifted up. When the hopper 14 rises to the uppermost position (position drawn by the alternate long and short dash line), the upper end portion 14a and the inclined portion 16 are flush with each other. 14 a and the inclined portion 16 are rolled and transferred into the hot water washing tub 3 a.

  The material for cold plastic working 11 that has rolled down in the hot water washing tank 3a is placed on the hot water washing bottom part 23b of the hot water washing lifting / lowering part 3b and washed with hot water in the hot water washing tank 3a. After a certain period of time, as shown in FIG. 5, when the hot water raising / lowering part 3b is lifted by the drive mechanism 17b, the hot water washing bottom part 23b of the hot water washing lifting part 3b and the hot water washing bottom part 23c of the hot water raising / lowering part 3c are connected. Since it becomes flush, it rolls in the direction of arrow A along the hot water washing bottom 23b, is transferred onto the hot water washing bottom 23c of the hot water raising / lowering part 3c, and is washed with hot water on the hot water washing bottom 23c. Similarly, as shown in FIG. 1, the cold plastic working material 11 is washed with hot water on the hot water washing bottoms in the order of the hot water raising / lowering parts 3d, 3e, 3f, and 3g.

  In addition, about the timing to which the hot water washing raising / lowering parts 3b-3g move up and down, the hot water washing raising / lowering parts 3b-3g are divided into two groups by skipping one by one along the order in which the raw material 11 for cold plastic processing is mounted on each hot water washing bottom part. That is, it is divided into two groups: a hot water raising / lowering unit 3b, 3d, 3f and a group of hot water raising / lowering units 3c, 3e, 3g. Control to move is performed. As a result, the cold plastic working material 11 being cleaned on the hot water washing bottoms of the hot water raising / lowering parts 3b, 3d, 3f moves the hot water raising / lowering parts 3b, 3d, 3f upward. It is respectively transferred onto the hot water washing bottoms of the hot water raising / lowering parts 3c, 3e, 3g belonging to the other group. That is, the material 11 for cold plastic processing exists on the hot water washing bottom part of three hot water raising / lowering parts which belong to any one group among six hot water washing raising / lowering parts 3b-3g.

  The material for cold plastic processing 11 washed on the bottom of the hot water washing lift 3g rolls along the bottom of the hot water washing lift 3g when the hot washing lifting 3g is moved upward. Thus, it is transferred into the lubricating tank 4a. Since each hot water wash bottom is formed with a slit, all hot water stays in the hot water washing tank 3a through the slit, so that the hot water is not transferred into the lubricating tank 4a and is used for cold plastic working. Only the material 11 is transferred into the lubricating tank 4a. As shown in FIG. 4, the material for cold plastic working 11 transferred into the lubricating tank 4a is cold plastic working material by the lubricant in the lubricating tank 4a on the lubrication bottom part 33b of the lubricating lift 4b. 11 surfaces are coated.

  After a certain period of time, the lubrication elevating unit 4b is moved upward by the drive mechanism 37b. When the lubrication elevating part 4b reaches the highest position, the lubrication bottom part 33b and the inclined part 6 are flush with each other, whereby the cold plastic working material 11 placed on the lubrication bottom part 33b rolls along the inclination. Then, it is transferred onto the conveyor belt 45 of the drying unit 5. While the cold plastic working material 11 is moved together with the conveyor belt 45 by the rotation of the conveyor belt 45, the lubricant coated on the surface of the cold plastic working material 11 is dried by the hot air blown from the jet part 44. Is done. At this time, the conveyor plate 45a constituting the conveyor belt 45 supports the cold plastic working material 11 by point contact, so that the contact area thereof is minimized. It is possible to prevent the lubricant coated on the surface of the material 11 from being peeled off.

  In addition, since the shape of the material 11 for cold plastic working may be any shape, if there is a dent on the surface, the lubricant may accumulate in the dent. If drying is performed in this state, the coating formed on the surface of the cold plastic working material 11 becomes non-uniform, so that the lubricant accumulated in the recess by the air blown from the air nozzle 47 Can be removed.

  As described above, after the hot water washing in the hot water washing part 3 is finished, the cold plastic working material 11 is lifted upward by moving the hot water raising / lowering part 3g upward, and then descends toward the coating part 4 It is transferred to the coating unit 4 by rolling downward obliquely along the hot water washing bottom part of the hot water washing lifting / lowering part 3g. Thereby, since the transfer time from the hot water washing part 3 to the application part 4 becomes short, the application | coating process efficiency of a lubrication agent can be improved, and also the time for which the raw material 11 for cold plastic processing touches external air during transfer. Therefore, the application performance of the lubricant can be improved. Further, the lubricant application device 1 does not require a means for transferring the cold plastic working material 11 between the hot water washing unit 3 and the application unit 4, so the hot water washing unit 3 and the application unit 4. Can be arranged next to each other, and downsizing can be realized.

  In this embodiment, the six hot water raising / lowering parts 3b-3g were provided in the hot water washing tank 3a, but it is not limited to six. You may change suitably according to the magnitude | size of the hot water bath 3a, the magnitude | size of each hot water raising / lowering part, hot water washing time, etc. Moreover, although one lubrication raising / lowering part 4b was provided in the lubrication tank 4a, it is not limited to one. You may change suitably according to the magnitude | size of the lubrication tank 4a, the magnitude | size of a lubrication raising / lowering part, application | coating time, etc. FIG.

  In this embodiment, six hot water raising / lowering parts 3b to 3g are provided in three rows in two rows in the hot water washing tub 3a, but this is not a limitation. You may provide six hot-water washing raising / lowering parts 3b-3g in 1 row at linear form. In this case, the storage part 2, the hot water washing part 3, the application part 4, and the drying part 5 are provided in a straight line, and the shape of the entire lubricant application device 1 is changed. That is, various variations can be easily given to the shape of the entire lubricant application device.
