It is easy to replace the entire conveyor unit 46. Moreover, since the conveyor unit 46 is separated from the drive system for driving the endless belt 51, the handling of the unit 46 is facilitated.

  As described above, when the conveyor unit 46 is removed from the moving table 37, the conveyor unit 46, which has been cleaned, is placed on the moving table 37 located at the retracted position. At this time, the engaging grooves 53a and 53a and the holes of the unit main body 47 are engaged with the protrusions 42 and the protrusions of the moving base 37, and the back of the unit main body 47 with respect to the regulating member 43 of the moving base 37. By contacting the side plate 53 on the side, the conveyor unit 46 is positioned at an appropriate position in the article conveying direction and the width direction with respect to the moving table 37.

  When the movable table 37 is pushed into the back side together with the conveyor unit 46 in the above-described state, the movable guide rails 36 and 36 slide along the fixed guide rails 35 and 35, and the back side surface of the conveyor unit 46 becomes the stopper 57. In addition to the contact, the side plate portion 38 of the moving table 37 contacts the operating shaft 40, whereby the conveyor unit 46 and the moving table 37 are positioned at the article conveying position. Further, the driven side coupling 55 fixed to the driving pulley 50 engages with the driving side coupling 56 pivotally supported by the supply frame 16 so that the drive transmission from the drive motor is possible.

  As described above, after positioning the conveyor unit 46 and the movable table 37 at the article conveying position, the fixing handle 41 is rotated upward so that the engagement shaft 41a faces the engagement groove 38a of the side plate portion 38. Thus, by rotating all the fixing handles 41 and screwing them into the operating shaft 40, the conveyor unit 46 is positioned and fixed at the article conveying position with respect to the supply frame 16. Then, after the operation rod 63 is pushed inward by the operation of the operation handle 64 and the movable pulley 48 is moved to the forward position by the operation of the advance / retreat mechanism 52 and switched to the tension position where the endless belt 51 is tensioned, By rotating the locking member 65 and locking it to the operation rod 63, the conveyor unit 46 can convey the article.

  Finally, when the side cover 26 in the open position is pulled up with the handle 34, the engaged member 32 engages with the groove 31a of the lock member 31 in the release position, and the lock member 31 rotates and locks. To the position. As a result, the opening 25 on the front side of the supply conveyor 10 is closed by the side cover 26, and the drawer side of the conveyor unit 46 is covered by the side cover 26, so that the operating part is not exposed. Since the lock member 31 is urged to rotate toward the lock position by the elastic member 33, the side cover 26 is not easily opened.

  As described above, the conveyor unit 46 of the supply conveyor 10 is configured to be pulled out to the front side where the operator performs the operation of the horizontal bag making and filling machine, so the article supply device is connected to the upstream side of the supply conveyor 10. Even in this state, maintenance such as drawing out the conveyor unit 46 to the outside for cleaning without separating the article supply device can be performed. Therefore, the operation at the time of detaching or attaching the conveyor unit 46 becomes extremely simple. Further, since the entire supply conveyor 10 is not moved, it is not necessary to adjust the relative positional relationship with the article supply device after the conveyor unit 46 is positioned at the article conveyance position, and the operation can be simplified. In addition, since the conveyor unit 46 can be taken in and out from the article transfer position and attached to and detached from the moving table 37, all work can be performed manually by the operator without using a tool.
