The head 22 which turns the finger 15 and 15a which hold | maintains the raw material 19 up and down is comprised.

The gear box 21 is rotated between the upper center of the gear box 21 and the upper plate 25 of the head 22 when the gear 23 coupled to the shaft of the servo motor 10 mounted on one side is rotated. It is configured to rotate the head 22 in a decelerated state by a drive (27) coupled to the shaft (26) laid on the shaft.

The drive 27 is coupled to the shaft 26 is coupled to the cross-roller bearing 29 and the flange 30 supported by the bearing on one side of the wave generator 28 is fixed to the gear 24 and the bolt coupling cross Insert the flexplane 32 into the roller bearing 29 to be supported by the bearing 34, and then bolt the outer ring of the flange 30 and the cross roller bearing 29 and the gear box 21 with bolts. On the other side of the wave generator 28, the flange 31 which is fixed to the circular plate 33 and the upper plate 25 of the head 22, which meshes with the flexplane 32, is supported by a bearing. After coupling, the inner ring of the cross roller bearing 29 and the circular splines 33 and the flange 31 are configured to be fixed by fastening with bolts.

Therefore, when the rotational direction and the rotational speed of the servo motor 10 are controlled, the rotational direction of the fingers 15 and 15a which are coupled to the lower part of the head 22 and holding the material can be freely adjusted.

The head 22 coupled to the lower portion of the gearbox 21 driven by the servo motor 10 and rotated has side plates 36 and 37 supported by intermediate plates 35 on both sides of the upper plate 25. A timing pulley 39 which is formed and coupled to a timing pulley 38 of the servo motor 11 mounted on an upper side of the side plate 36 and a drive 27a coupled to a lower portion of the side plate 36. It is configured to be connected to the timing belt 40 to transmit power.

The drive 27a couples a cross roller bearing 29a and a flange 30a supported by a bearing to one side of the wave generator 28a fixed to the timing pulley 39 and the bolt, but the cross roller bearing 29a is coupled to the timing pulley 39. Insert the flexplane 32a inward so as to be supported by the bearing 34a, and then fasten the outer ring and the side plate 36 of the flange 30a and the cross roller bearing 29a by bolts to fix the wave, and the wave On the other side of the generator 28a, the circular ply 32a engaged with the flexpline 32a and the flange 31a supported by the bearing are combined, and then the inner ring of the cross roller bearing 29a and the circular ply 33a and the flange are engaged.

Fixing the fastening opening 46 to the 45, the operation detecting rod 45 is in contact with the material 19 is lifted up, the sensor fixed to the bracket (48) on the top of the finger support (41) (41a) ( 47) to detect the operation.

The finger supports 41 and 41a are mounted with cylinders 49 and 49a to which the fingers 15 and 15a are coupled, respectively. The cylinders 49 and 49a are inserted into the body 50 to move forward and backward. It consists of a piston (51) and a cam (53) coupled to the piston (51) by a push rod (52), and double-acting fingers (15) (15a) engaged with the cam (53) and sliding left and right.

Looking at the material supply device action of the carrier loader of the present invention configured as described above are as follows.

The carrier 12 with the material supply device 20 of the present invention travels on the traveling beam 3 constituting the carrier loader 1, wherein the carrier motor 8 mounted on the carrier 12 The pinion 6 is driven by being engaged with the rack 4 formed on the top of the traveling beam 3.

In addition, the material supply device 20 constituting the carrier 12 is moved up and down to bring in or take out the material, wherein the pinion (7) of the servo motor (9) mounted on the carrier 12 to the platform 14 It is raised and lowered by engaging with the formed rack 5 and rotating.

When rotating the fingers 15, 15a constituting the material supply device 20 of the present invention provided on the lower end of the platform 14 to the servo motor 10 coupled to the upper side of the gear box 21 When the gear 23 is rotated by applying power, the gears 24 engaged with each other rotate to decelerate to the drive 27.

That is, when the gear 24 rotates and the wave generator 28 fixed by bolting with the gear 24 rotates, the flexpline 32 is elastically deformed in an elliptical shape by the wave generator 28. In the long axis portion of the ellipse, the circular ply 33 and the teeth are engaged, and in the short axis portion, the teeth are completely separated.

If the wave generator 28 is rotated one clockwise in the state in which the circular ply 33 is fixed, the flex ply 32 is elastically deformed and the number of teeth is reduced by the circular ply 33. The wave generator 28 moves in the opposite direction to the rotational direction of the wave generator 28, i.e., counterclockwise by two teeth.

Accordingly, the lower fingers 15 and 15a of the head 22 which are combined with the gear box 21 and decelerately rotate to the drive 27 are rotated.

When turning the fingers 15 and 15a for carrying in or taking out the raw material 19 up and down, a power is applied to the servo motor 11 mounted on the side plate 36 of the head 22 so as to supply a timing pulley ( 38 rotates the timing pulley 39 coupled to the wave generator 28a constituting the lower drive 27a of the side plate 36 by the timing belt 40 interconnected to the drive 27a. Deceleration is achieved.

The action of the drive 27a for turning the fingers 15 and 15a up and down is the same as the action of the drive 27 configured in the gearbox 21 for the rotation of the fingers 15 and 15a described above. Do.

When the timing pulley 39 rotates to decelerate by the drive 27a, the finger support 41 and the finger support 41 and the holder 43 are bolted to the flange 31a of the drive 27a. When the finger support 41a of the other side fixed by the pivot is turned, the fingers 15 and 15a respectively coupled to the finger supports 41 and 41a are pivoted up and down.

Each finger 15, 15a coupled to the finger supports 41, 41a is slid by a cylinder 49, 49a connected to an air compressor 13 and an air hose mounted on the carrier 12. The material 19 is held and released. When the piston 51 formed on the body 50 of the cylinder 49 or 49a moves forward, the cam 53 fixed by the piston 51 and the push rod 52 is pushed. The double-acting fingers 15 and 15a are opened, and when pulled in opposite directions, they are closed.

The present invention described above is coupled to a timing pulley and a drive coupled to a servo motor with a finger of a material supply device for loading or unloading a material when processing the material by using a carrier loader installed in one line. By rotating the timing pulley forward and backward with the timing belt, the up / down turning operation of the finger is made faster, and the servo motor and the drive are provided on the top of the head to rotate the finger so that the processing direction or the carrying in / out direction of the material It is a very practical design that can respond appropriately to changes.
