[Problems to be solved by the device]

 The conventional PTP packaging machine is configured as described above, and when the scrap bag 15a or 15b becomes full, the scrap bag 15a or 15b is manually replaced and scraps are scraped, but the height from the floor surface to the scrap cutter 13 is low. Since the upper installation space is small, large scrap bags 15a and 15b cannot be installed. Therefore, workers often have to replace the scrap bags 15a and 15b (for example, every 15 to 20 minutes), which is an obstacle to unmanned work of the PTP packaging machine.

Also, recently, the PTP packaging machine has come to be covered with a cover 18 to prevent dust, but the cover 18 has to be opened and taken out every time the scrap bags 15a and 15b are replaced. Very troublesome. For this reason, the cover 18 is provided up to the lower portion of the scrap cutter 13, and the lower portion is opened to facilitate the taking in and out of the scrap bags 15a and 15b. However, in this case, there is a problem in that the dust is intruded from below, and the meaning of providing the cover 18 is lost.

The present invention has been made to solve the above-mentioned problems, and by installing a scrap container having a large capacity, the replacement frequency is reduced, and the scrap container can be opened without opening the cover or opening the lower part. The purpose is to obtain a scrap discharge device for a PTP packaging machine in which the container can be replaced.

[0012]

[Means for Solving the Problems]

 The scrap discharge device of the PTP packaging machine according to the present invention is provided with a belt conveyor below the scrap cutter to convey the scrap to the outside of the machine. In addition, in the scrap discharge device of the PTP packaging machine, a conveyor belt conveyor for scrap is provided below the scrap cutter, and a conveyor belt conveyor for conveying the scrap conveyed by the conveyor belt conveyor to the outside of the machine is provided. It is a thing. Further, the above-mentioned discharging belt conveyor is installed with the outside of the machine inclined at a high angle.

[0013]

[Action]

 The scrap of the PTP sheet cut by the scrap cutter falls on the belt conveyor, is transported outside the machine, and is accumulated in the scrap container. Further, the scrap of the PTP sheet cut by the scrap cutter falls on the conveyor belt conveyer, is conveyed and is transferred to the discharge belt conveyor, and is conveyed outside the machine. Then, they are accumulated in a scrap container provided outside the machine. Further, by raising the outside of the discharging belt conveyor, a scrap container having a large capacity can be used.

【Example】

 Embodiment 1 FIG. 1 is a plan view of an embodiment of the present invention, and FIG. 2 is a front view thereof. It should be noted that the same parts as those of the conventional technique described in FIG. 25 is a belt conveyor for transporting scrap, one end of which is located below the scrap cutter 13 and moves in the direction of arrow a, and 26 is provided on the other end side of the conveyor belt conveyor 25 in direct contact therewith. A belt conveyor for discharging scrap, the tip of which extends outside the machine, that is, outside the cover 18 and moves in the direction of arrow b, and 27 is a scrap container installed below the end of the discharging belt conveyor 26. The cover 18 is provided up to the lower end of the device.

In the present invention configured as described above, the scraps 21a, 21b, 21c, ... Cut by the scrap cutter 13 fall on the conveyor belt conveyor 25, are conveyed in the direction of arrow a, and are discharged. It is transferred onto the conveyor 26, conveyed in the direction of arrow b, conveyed to the outside of the cover 18, and discharged into the scrap container 27. When the scrap container 27 is full, the scrap container 27 is replaced with another scrap container, and the scrap in the scrap container 27 is discarded.

In this case, since a large space and height can be obtained on the discharge side of the discharge belt conveyor 26, a large-capacity scrap container 27 can be installed. Therefore, the frequency of exchanging the scrap container is greatly increased. It can be lowered (for example, about once an hour). Further, since the scrap container 27 is installed outside the cover 18, the cover 18 will not be opened at the time of replacement when it is full.

Embodiment 2 In the scrap discharging apparatus described above, the discharging belt conveyor 26 may be installed horizontally, but if it is installed with a high inclination on the outside of the machine as shown in FIG. Since the scrap container 27 having a higher capacity can be installed with a larger capacity, the frequency of exchanging the scrap container 27 can be further reduced.

Although the embodiment of the present invention has been described above, the PTP packaging machine for implementing the present invention is not limited to the one shown in the drawing, and the PTP packaging machine of other structure can be implemented. Although the present invention has been shown to be applied to a PTP packaging machine having a cover, it may be implemented to a PTP packaging machine having no cover. Furthermore, although the case where the discharge belt conveyor is provided orthogonal to the transfer belt conveyor is shown, the installation angle of the discharge belt conveyor with respect to the transfer belt conveyor can be appropriately selected. Further, although the case where the scrap is discharged to the outside of the machine by the conveyor belt conveyor and the discharge belt conveyor is shown, the scrap may be directly conveyed to the outside of the machine from below the scrap cutter by one belt conveyor.

[0019]

[Effect of device]

 As is clear from the above description, in the present invention, the belt conveyor is provided below the scrap cutter of the PTP packaging machine so that the scrap is accumulated in the scrap container provided outside the machine. You can get a large space underneath. Therefore, since a scrap container having a large capacity can be used, the frequency of exchanging the scrap container can be significantly reduced, and the work efficiency can be improved.

A belt conveyor for scrap transportation is provided below the scrap cutter, and a discharge belt conveyor for transporting scrap carried by the conveyor belt conveyor is provided outside the scrap cutter. The tip of the conveyor can be placed at a high place. Therefore, the height from the floor surface to the discharge belt conveyor can be set high, and a scrap container having a larger capacity can be used.

Further, since the scrap is transported to the outside of the machine, the scrap container can be installed outside the machine. For this reason, since it is not necessary to open the cover when exchanging the scrap container, not only is the exchanging of the scrap container easy, but the cover can be installed up to the lower end of the PTP packaging machine, and dust is reliably prevented from entering. be able to.

Further, by raising the outside of the discharging belt conveyor to increase the height from the floor surface to the discharging belt conveyor, it is possible to use a scrap container having a large capacity. Therefore, the frequency of exchanging scrap containers can be further reduced.
