Having an anvil 62 which is arranged to face the printing machine 61 with the material Fw in between and serves as a backing for printing on the strip-shaped packaging material Fw has the same configuration as the conventional bag-making filling and packaging machine 50. Since the configuration has been described using the same reference numerals as those assigned in FIG. 4, detailed description thereof will be omitted here.

In the supply path Ws of the packaging material supply unit 52, a guide roller 64 around which the strip-shaped packaging material Fw is wound is provided on the downstream side of the print inspection device 63. The mounting position of the guide roller 64a on the most upstream side of the guide rollers 64 can be changed in the vertical direction as shown by an arrow. By changing the mounting position of the guide roller 64a, the length of the supply path of the strip-shaped packaging material Fw from the arrangement position of the printing device 60 to the bag-making filling / packaging machine section 51 can be changed. The printing position on the band-shaped packaging material Fw is determined in the width direction of the band-shaped packaging material Fw according to the specifications of the packaging bag B to be manufactured, and the length of the packaging bag B is also determined in the supply direction of the band-shaped packaging material Fw. It is decided according to the specifications of the packaging bag B including.

The printing position of the strip-shaped packaging material Fw in the supply direction differs for each strip-shaped packaging material Fw used for packaging. In order to cope with this, changing the installation position of the printing device 60 itself to the supply direction of the strip-shaped packaging material Fw is complicated. Therefore, the mounting position of the guide roller 64a in the middle of the supply path Ws is changed without changing the mounting position of the printing device 60 in the packaging material supply unit 52. If the path length of the band-shaped packaging material Fw from the arrangement position of the printing device 60 to the bag-making filling and packaging machine section 51 is changed and the printing device 60 prints on the band-shaped packaging material Fw passing in front of the bag, the printing is performed.

It is made up.

When the inspection door 2 is opened, the printing machine 61 and the printing inspection device 63 remaining inside the cover body 1 can be seen as shown in the figure. Since the inspection door 2 opens to the outside of the cover body 1, it does not interfere with the packaging material supply unit 52. When the printing machine 61 prints on the strip-shaped packaging material Fw, it is important that the anvil unit 4 is arranged at a position facing the printing machine 61 with the strip-shaped packaging material Fw interposed therebetween. The printing machine 61 can be moved in the width direction W of the strip-shaped packaging material Fw so that the printing position on the strip-shaped packaging material Fw can be changed. This movement of the printing machine 61 is usually performed manually or automatically by a printing machine moving mechanism (not shown) so as to move to a position set by the control device based on the printing specifications of the packaging bag or the like.

The anvil unit 4 is provided inside the inspection door 2, and includes a substantially box-shaped holder 5 and a mat-shaped anvil 6 attached to the holder 5. The anvil 6 is a backing for printing on the strip-shaped packaging material Fw performed by the printing machine 61, and is a material and a thickness capable of receiving an impact (impact force) generated when the printing machine 61 prints on the strip-shaped packaging material Fw. It has. The inspection door 2 is appropriately locked by a lock 7 that also serves as a handle 7 so as not to open unexpectedly when the door 2 is closed.

A moving mechanism 10 is provided so that the anvil unit 4 can be moved in the width direction (with the inspection door 2 closed) W of the strip-shaped packaging material Fw. The moving mechanism 10 includes two parallel guide rods 11 and 11, and both ends of the guide rods 11 and 11 are attached to support portions 8 and 8 provided inside the window frame 2a of the inspection door 2. There is. The holder 5 is formed with two guide holes 12 and 12 penetrating in parallel, and the guide rods 11 and 11 are fitted into the guide holes 12 and 12, so that the holder 5 is fitted with the guide rods 11 and 11. You will be guided along. In order to facilitate the movement of the holder 5, sleeves (not shown) that can slide smoothly with the guide rods 11 and 11 can be appropriately attached to the guide holes 12 and 12.

The moving mechanism 10 for moving the holder 5 further includes a motor 14 as a drive source provided in the inspection door 2 and a screw mechanism 15 for converting the rotational output of the drive source into linear movement. The screw mechanism 15 includes a screw shaft 16 whose axis extends parallel to the guide rod 11, and a nut 17 provided on the holder 5 and screwed onto the screw shaft 16. Both ends of the screw shaft 16 are rotatably supported by bearings with respect to support portions 8 provided at appropriate positions on the inspection door 2. The holder 5 is formed with a through hole through which the screw shaft 16 penetrates. The nut 17 is attached to the holder 5 in a fixed state so as not to move in the axial direction and to rotate.

The moving mechanism 10 further includes a sprocket 19 provided on the output shaft of the motor 14 and a chain 21 wound around the sprocket 20 provided on the screw shaft 16. The rotational output of the motor 14 is the sprocket 19, It is transmitted to the screw shaft 16 via the power transmission mechanism of the 20 and the chain 21.

According to the moving mechanism 10, when the screw shaft 16 is driven by the motor 14, the nut 17 fixedly provided on the holder 5 is moved along the screw shaft 16 together with the holder 5 by the screw feeding action of the screw mechanism 15. .. When the inspection door 2 is closed, the guide rods 11 and 11 and the screw shaft 16 extend in the width direction W of the strip-shaped packaging material Fw. Guided in the width direction W.

According to this embodiment, when the opening / closing door 2 is closed, the anvil 6 attached to the opening / closing door 2 is at the position P1 facing the printing machine 61. At this time, the distance between the printing machine 61 and the anvil 6 is about 3 mm as usual. When the opening / closing door 2 is in the closed state, even if an attempt is made to remove the strip-shaped packaging material Fw from the printing device 60, load the strip-shaped packaging material Fw, or perform maintenance work on the printing device 60, the inside of the cover body 1 Since access is not possible, when attempting to perform such work, the inspection door 2 of the back wall 32 is opened to secure access to the inside of the cover body 1.

At the same time, the operation of opening the opening / closing door 2 is an operation of moving the anvil unit 4 attached to the opening / closing door 2 away from the printing machine 61. That is, the distance between the printing machine 61 and the anvil unit 4 is greatly widened only by opening the opening / closing door 2 to the outside. Since the opening / closing door 2 opens while rotating around the hinge 2b, the movement when the anvil 6 starts to move away from the opposite position is the movement away from the state facing the printing machine 61 in the direction orthogonal to the rear, and widens the interval. It will be efficient as an operation. The separation position P2 of the anvil 6 is such that the operator can easily remove and load the strip-shaped packaging material Fw or maintain the printing device 60, for example, the opening / closing door 2 is sufficiently spaced from the printing machine 61 up to 90 degrees. It can be in an open position. At the separated position, not only the access to the anvil unit 4 is easy, but also the access to the printing machine 61 remaining inside the cover body 1 is easy.

When the above work by the operator is completed, the opening / closing door 2 is closed. The anvil unit 4 attached to the opening / closing door 2 returns to a position facing the printing machine 61 when the opening / closing door 2 is closed with respect to the back wall 32. The gap between the printing machine 61 of the printing device 60 and the anvil 6 is about 3 mm, as in the case of the conventional bag-making filling and packaging machine. When the strip-shaped packaging material Fw is loaded, when the opening / closing door 2 is closed, it is sandwiched between the printing machine 61 and the anvil 6 at the same time. In this way, by opening and closing the opening / closing door 2, the anvil 6 can be moved to a separated position sufficiently away from the printing machine 61 and returned to the original facing position, so that the above work is a labor-free work. Become. In this embodiment, when the printing position is changed in the width direction W on the strip-shaped packaging material Fw, the printing machine 61 and the printing inspection device 63 are moved in the width direction of the strip-shaped packaging material Fw. By moving the strip-shaped packaging material Fw in the width direction W by the moving mechanism 10, the position facing the printing machine 61 can be maintained.

In the anvil unit 4 of this embodiment, the anvil 6 is replaceably held by the holder 5, and the anvil 6 moves together with the holder 5 when the holder 5 is moved. By holding the anvil 6 replaceably with the holder 5, if a problem such as deterioration of the anvil 6 occurs, the old anvil can be removed from the holder 5 and a new anvil can be attached to the holder 5 and replaced. .. Since the holder 5 is responsible for moving the anvil 6 with respect to the printing machine 61, and the anvil 6 is not directly related to the movement, it is possible to avoid an inadvertent influence on the anvil 6.

FIG. 3 shows another example of moving the anvil. FIG. 3A shows a position P1 facing forward with respect to the printing machine 61 by advancing and retreating the anvil 6 (with the holder 5 supporting the anvil 6) with respect to the printing machine 61 in a posture facing the printing machine 61. And the separation position P2 retracted from the printing machine 61. As a structure for advancing and retreating, a structure is conceivable in which a plurality of guide members 27, 27 fixed to the holder 5 are guided through the through holes 26, 26 formed in the frame 25 of the packaging material supply unit.

In FIG. 3B, the anvil 6 is printed by attaching the holder 5 (along with the anvil 6 supported by the holder 5) to the arm 28 and rotating the arm 28 around a rotation shaft 29 provided in the packaging material supply unit. The structure is such that the position P1 facing the machine 61 and the position P2 separated from the printing machine 61 by rotating 90 degrees, for example, as shown in the figure. In each case, the direction in which the movement from the facing position P1 to the separation position P2 starts is the direction in which the facing position P1 is opposed to and away from the facing position P1, so that the opening operation becomes efficient. Since the printing machine 61 and the anvil 6 can be accessed at the separation position P2, work such as removal, loading, and maintenance of the strip-shaped packaging material Fw becomes easy.
