On the other hand, the seal jaw 52 of the second seal unit 50b is supported at one end by the arm member 92b and at the other end by the arm member 92d. The arm members 92b and 92d are members that rotate about the turning center C2, and are supported by the turning shaft 96 so as to be relatively rotatable.

  Each of the sealing jaws 51 and 52 has a heater (sealing heater) 71 inside (see FIGS. 7 and 8). The heater 71 heats the sealing surfaces of the sealing jaws 51 and 52 so that a part of the tubular film F sandwiched between the left and right sealing jaws 51 and 52 is heat-sealed. The configuration of the seal jaws 51 and 52 will be described in detail later.

  The Schmitt couplings 98 and 99 are composed of three discs connected by links, and are shaft couplings that transmit the rotation of the input shaft to the output shaft. These Schmitt couplings 98 and 99 can rotate the input shaft even when the output shaft moves in a plane with respect to the input shaft fixed in a plane to change the axial distance between the two. Can be communicated to.

  The pivot shaft 94 is pivotally supported by the horizontal movement plates 62a and 61a, and the pivot shaft 96 is pivotally supported by the horizontal movement plates 62b and 61b. These horizontal movement plates 62a, 61a, 62b and 61b are horizontally moved by a lateral drive mechanism 55 shown in FIG. The horizontal movement plates 61a and 62a move in the same manner, and the horizontal movement plates 61b and 62b move in the same manner. Here, the horizontal drive mechanism 55 will be described by taking the horizontal movement plates 61a and 61b as an example. As shown in FIG. 5, the lateral drive mechanism 55 includes a drive mechanism 65 for moving the horizontal moving plates 61a and 61b close to or away from each other, and supports the horizontal moving plates 61a and 61b so as to be slidable in the horizontal direction.

By such a driving mechanism 65, the ball screw 80a rotates, whereby the horizontal moving plates 61a and 61b can be brought close to each other or separated from each other.
[Configuration of seal jaw]
As described above, the sealing jaws 51 and 52 are members for contacting and heat-sealing the tubular film F, and include a heater 71, a cutting mechanism 72, a punch punching mechanism 73, a sensor (not shown), and the like. Have. Further, the seal jaws 51 and 52 are held between the arm members 92a and 92c, and receiving members (seal jaw receiving members) 93a and 93b that turn around the turning centers C1 and C2 (see FIGS. 4 and 7). ) Is attached via an intermediate member 70.

  The intermediate member 70 is interposed between the receiving members 93 a and 93 b and the seal jaws 51 and 52, and has an attachment position adjusting mechanism 74 for the seal jaws 51 and 52. As shown in FIG. 9, the attachment position adjusting mechanism 74 is detached from the receiving members 93 a and 93 b together with the seal jaws 51 and 52 when the seal jaws 51 and 52 are replaced. Then, as shown in FIG. 10, the seal jaws 51 and 52 are removed from the intermediate member 70, and the seal jaws having a desired function can be replaced, whereby the seal jaws can be easily replaced. At this time, the new seal jaws 51 and 52 attached to the intermediate member 70 on the seal unit 50a side turn the screw 74a of the attachment position adjusting mechanism 74 in a predetermined direction, thereby opposing the seal unit 50b side. The height position of the sealing jaws 51 and 52 is adjusted. Here, when the intermediate member 70 is attached to the receiving members 93a and 93b, the intermediate member 70 is always attached to a fixed position. For this reason, by previously adjusting the height positions of the seal jaws 51 and 52 with respect to the intermediate member 70, it is not necessary to perform troublesome adjustment of the height position of the seal jaws every time the seal jaws 51 and 52 are replaced. .

As shown in FIGS. 7 and 8, two heaters 71 are inserted into the seal jaws 51, 52 along the longitudinal direction of the seal jaws 51, 52. And it receives the electric power supplied from the electrical wiring 76a, it heats, and the sealing jaws 51 and 52 are heated to the sealing temperature corresponding to the cylindrical film F.
The cutting mechanism 72 is provided on the sealing jaws 51 and 52 on the seal unit 50a side, and includes a cutter 72a and a cutter driving mechanism 72b. The cutter 72a is configured so that the sealing jaws 51, 52 on the seal unit 50b side from the slide space 53 formed in the seal jaws 51, 52 on the seal unit 50a side by the cutter driving mechanism 72b in accordance with the timing of sealing the cylindrical film F. You can move forward. The cutter driving mechanism 72b is an air cylinder for reciprocating the cutter 72a in a predetermined direction. Thereby, the upper end portion of the sealed bag (cylindrical film F) is cut by pressing the cutter 72a between the sealing jaws 51 and 51 or between the sealing jaws 52 and 52 at the substantially central position in the width direction of the sealing portion. can do. As a result, the bags can be divided one by one and discharged to the subsequent chute conveyor 19 (see FIGS. 1 and 2).

  The punch hole punching mechanism 73 is provided on the seal jaws 51 and 52 on the seal jaw 52 side, and has a burn-through heater (heater for punch punching) 73a. The burn-through heater 73a has a substantially cylindrical punch hole heater processed into a hole punch shape at the tip. And the size reduction of the punch punching mechanism 73 is implement | achieved by giving the heat insulation process to the front-end | tip part. Also, when the seal jaws 51 and 52 come into contact with the cylindrical film F so that the burn-through heater 73a is in contact with the seal portion, the tip portion of the substantially C-shaped heater is pressed against the seal portion, and the bag is heated by heat and pressure. It is possible to form a punch hole for hanging at the time of product display in the upper part (seal part) of the product.

  The temperature control of the burn-through heater 73a is performed by 100V current control. For this reason, a setting can be changed with the remote control etc. which operate the bag-making packaging machine 1, for example. This makes it possible to punch holes with good quality by easily changing the set temperature of the heater according to the material of the film F and the like. Further, by adopting a burn-through type heater as in the present embodiment, it is possible to obtain a product with reduced leakage and high suspending strength as compared with the hole punching.

  Further, as shown in FIG. 7, electric wiring 76a for supplying electric power to the heaters 71 and 73a is connected to the heater 71 and the burn-through heater 73a. And this electric wiring 76a is connected to the power supply part via the connector (connection connector) 75a-75c via the electric wiring 76b provided in the upstream of the connector 75a-75c seeing from the power supply part which is not shown in figure. Yes. 8 to 10, the electrical wiring connected to the heater 71 and the like is not shown, but this is for the convenience of explanation, and actually the electrical wiring 76a is not shown in FIG. It shall be connected.

[Replacement of seal jaw]
Here, the replacement of the sealing jaws 51 and 52 will be described.
Each of the sealing jaws 51 and 52 has a built-in burn-through heater 73a and a cutter 72a, and is provided with a function of making a punch hole in the sealing portion or dividing the bag individually. For this reason, it is frequently performed to replace the sealing jaws 51 and 52 equipped with necessary functions according to the type and application of the product to be made. However, the configuration of the conventional sealing jaw requires several hours for replacement, and it is very troublesome because the height position of the sealing jaw needs to be adjusted every time after replacement.

Therefore, in the lateral seal mechanism 17 of the present embodiment, as shown in FIGS. 8 to 10, in order to shorten the time required for the replacement of the seal jaws 51 and 52 and the adjustment of the height position after the replacement, the efficiency is improved. The configuration is adopted.
That is, in the present embodiment, the seal jaws 51 and 52 on the seal unit 50a side swivel around the swivel center C1 via the intermediate member 70 provided with the attachment position adjusting mechanism 74 as shown in FIG. It is attached to the receiving members 93a and 93b. Therefore, when exchanging the seal jaw 51, as shown in FIG. 9, after removing only the cutter 72a while leaving the cutter driving mechanism 72b as it is, the receiving members 93a, 93b and the intermediate member 70 are fixed. The sealing jaws 51 and 52 can be removed together with the intermediate member 70 by removing the screw 95. On the other hand, when replacing the seal jaw 52, after removing the burn-through heater 73a, the screw 95 for fixing the receiving members 93a, 93b and the intermediate member 70 is removed, and the seal jaws 51, 52 are attached to the intermediate member 70. And can be removed. Thereafter, each sealing jaw 51, 52 can be removed from the intermediate member 70 and replaced with a new sealing jaw having a desired function.

[Features of horizontal sealing mechanism of this bag making and packaging machine]
(1)
As shown in FIGS. 7 and 8, the lateral sealing mechanism 17 of the bag making and packaging machine 1 of the present embodiment is configured so that the sealing jaws 51 and 52 are swung around receiving centers 93 and 93 b around the turning centers C <b> 1 and C <b> 2. It connects with the intermediate member 70 with respect to it. The intermediate member 70 is attached to a fixed position in the receiving members 93a and 93b, and has an attachment position adjusting mechanism 74 that adjusts the height positions of the seal jaws 51 and 52.

  Accordingly, when the seal jaws 51 and 52 are replaced, as shown in FIG. 9, the connection between the intermediate member 70 and the receiving members 93 a and 93 b is disconnected and the seal jaws 51 and 52 together with the intermediate member 70 can be removed. it can. As a result, the height position of the seal jaws 51 and 52 is adjusted by the attachment position adjusting mechanism 74 while being integrated with the intermediate member 70 before the seal jaws 51 and 52 are attached to the receiving members 93a and 93b. This can be done in advance. For this reason, after the seal jaws 51 and 52 are attached to the receiving members 93a and 93b, the seal jaws 51 and 52 are required for replacement and position adjustment as compared with the conventional configuration in which the height positions of the seal jaws 51 and 52 are adjusted. The time can be greatly shortened, and the seal jaw can be replaced efficiently. In addition, since the sealing jaws 51 and 52 are attached and detached via the intermediate member 70 which can be easily attached to the receiving members 93a and 93b, the sealing jaws 51 and 52 can be easily replaced even if they are not skilled workers. Can reduce labor costs. Further, since the seal jaws 51 and 52 having a plurality of functions can be exchanged efficiently, the one that has been conventionally handled by a plurality of horizontal seal mechanisms from the viewpoint of time efficiency required for exchange and adjustment is 1 This can be dealt with by the horizontal sealing mechanism of the base, and the cost can be reduced.

  For adjusting the height positions of the seal jaws 51 and 52, the seal jaws 51 and 52 and the intermediate member 70 are exchanged as a set, so that the seal jaws 51 and 52 on the opposite seal unit 50b side can be adjusted. On the other hand, once the adjustment is made, it is not necessary to adjust the position by simply attaching it to the receiving members 93a and 93b. For this reason, it is possible to exchange and adjust the seal jaws more efficiently by exchanging the seal jaws 51 and 52 with the intermediate member 70 as a set.

In the lateral seal mechanism 17 of the bag making and packaging machine 1 of the present embodiment, as shown in FIGS. 7 and 8, heaters 71 are incorporated in the seal jaws 51 and 52, and an electric wiring 76 a is provided in each heater 71. It is connected. And this electrical wiring 76a is connected with the electrical wiring 76b connected to the power supply part side which is not shown in figure via the connectors 75a and 75c.

  Thereby, when exchanging the seal jaws 51 and 52 incorporating the heater 71, the electrical wiring 76a and the electrical wiring 76b can be disconnected at the portions of the connectors 75a and 75c. Therefore, since it is not necessary to use a nerve for handling the electric wiring 76a when the seal jaws 51 and 52 are replaced, the seal jaws 51 and 52 can be replaced more efficiently.

(3)
As shown in FIGS. 7 and 8, the lateral seal mechanism 17 of the bag making and packaging machine 1 of the present embodiment has a punch hole mechanism 73 (burn-through heater 73 a) mounted inside the seal jaws 51 and 52. Yes.
For this reason, it is not necessary to separately provide a large punching machine, and the sealing jaws 51 and 52 can be attached and detached more easily.

In the lateral seal mechanism 17 of the bag making and packaging machine 1 of the present embodiment, a cutter 72a is built in the seal jaws 51 and 52 on the one seal unit 50a side. Further, as shown in FIG. 9, a space 53 for sliding the cutter 72a by the cutter driving mechanism 72b is formed in the sealing jaws 51 and 52.

Accordingly, the cutter 72a can be easily removed by sliding the cutter 72a, and it is not necessary to remove the cutter driving mechanism 72b that drives the cutter 72a. For this reason, even if it is the sealing jaws 51 and 52 which mount the cutter 72a (cutting mechanism 72), the simple attachment / detachment of the sealing jaws 51 and 52 is attained.
