Passing, therefore, coaxially filling tube 20 and the inside of the pipe detonating cord S passes through the free from packing material of the tip Z sleeve in a pre-prepared oblong capsule W from the explosive. In the zone free from packing material of the tip Z sleeves it is clamped in the clamping clips CI, C2, and thus is held.

Presented on Fig.option 2 implementation device portioning and packaging in accordance with the invention differs from that described on the basis of Fig.1 form filling tube 120 and the supply pipe 140. Filling tube 120, as well as filling pipe 20 in accordance with Fig.1, attached to neizobrazimo transporting device 10, through which the packaged explosive is fed through the filling tube 120.

Filling tube 120 has a first portion 122, the second part 124, and a third portion 126. Part 122 and 124 are parallel to the axis at a distance from each other. The third part 126 filling pipe connects the first and second parts 122, 124 each other. Its Central longitudinal axis intersects the Central longitudinal axis of the first and second portions 122, 124. As a result of this arrangement of the parts 122, 124, 126 on the filling tube 120 is formed S-shaped or Z-shaped ledge. Presented on Fig.2 the angle of the ledge, corresponding to about 90°, can be, however, in accordance with the consistency of Packed explosives and to change the nature of the flow, and more than 90°.

Used in the embodiment of the device of the portioning and packaging in accordance with the invention according to Fig.2 the supply pipe 140 has a diameter comparable to the diameter of the supply pipe 40 of Fig.1. It is, however, not curved, and passes linearly and coaxially of the Central longitudinal axis of the first part 122 of the filling pipe. Its axial length is greater than the axial length of the first part 122 of the filling pipe. The supply pipe 140 through the first part 122 of the filling pipe. In the connection zone of the first part 122 filling the pipe with the third part 126 filling pipe it enters into the filling pipe 120 and passes to the zone between the entrance filling pipe 120 and a machine for applying clips.

In the direction F filling with pushing directly behind the inlet of the filling tube 120 is also the Ashina to overlay clips, which presents a displacement unit 30.

At the end from the entrance filling tube 120 is also stock bag packaging sheath V, which immediately before the inlet of the filling tube 120 is closed, the first clamping clip C1. Next in the direction of F filling with pushing for this clamping clip C1, formed by displacing unit 30 that is free from packing material of the tip Z bag packaging sheath V is a second clamping clip C2. This clip closes the end of the previously manufactured capsules with explosive W.

Stock detonating means S, as detonating cord S, in this example embodiment of the invention is located under the filling tube, in the area between the S-shaped or Z-shaped ledge filling tube 120 and nasobrahan handling device, so that shot with cumulative roller R detonating cord S without additional reversal can be conducted into the inlet of the supply pipe 148 140. Therefore, such an implementation option is recommended for sensitive curves of detonating cords S. Detonating cord S passes in this case, linearly and coaxially of the first part 122 of the filling pipe through the feeding tube 140 and out of it oriented towards filling with pushing the input re rsta 146 between the input filling pipe 120 and a machine for applying clips, directly in the area of the first clip C1. Detonating cord S passes through the free of packing material the tip of a tubular packaging casing, and, as already described in connection with Fig 1, is clamped into the clamping clip C1, C2 and held them.

Manufacturer containing the detonating means of capsules containing the explosive in accordance with the invention will be explained hereinafter in more detail. Using the conveying device 10 packaged explosive served on the filling tube 20, 120. Through facing the direction of transportation of the inlet of the explosive out of the filling tube 20, 120 and, thus, fills closed with one hand clamping clip ART section of the bag packaging shell V. due to the pressure of filling the next portion of the bag packaging sheath V is removed from stock for filling the tube 20, 120. When the desired amount of explosive fills covered on one side part of the bag packaging sheath V, the further supply of explosives is terminated. The displacing unit 30 machines for applying clamps pinched filled packaging casing V right in front of the filling pipe. In the cultivation of the displacing unit 30 is formed free from packing material of the tip Z packaging shell. This con is IR Z onto the second clamp clip C2, which closes overlapped with one hand and filled the Packed product area packaging bag shell V and, thus, forms an oblong capsule W from the explosive. At the same time or at the end of this process, free from the packing product tip Z packaging shell onto the new first clamping clip C1, which forms the initial tip next oblong capsule W from the explosive. In conclusion, just made capsule W from the explosive using the appropriate separator is separated from the newly formed tip of the sleeve and is removed from the packaging device.

Before filling process detonating cord S is held by the supply pipe 40, 140 through the inlet of the filling tube 20, 120 to the outside and is clamped in the first clamping clip C1. During transport of explosives by filling the tube 20, 120, together with the explosive on the filling tube 20, 120 in bag packaging sheath V served and detonating cord S. When closing the already completed section of the packaging sheath V detonating cord is automatically clamped in the first and second clamping the clip C1, C2.

Clamped in the first clamping clip C1 detonating cord S is removed when the cumulative roller R at the same speed as the packaging and the internal shell V with your stock. Therefore, guaranteed that the detonating cord without forming kinks straight line passes through the capsule W from the explosive.

However, cumulative roller R for stock detonating cord S may also be provided corresponding to the braking device to prevent uncontrolled descent of the detonating cord S.

To be able to simply and reliably in contact with a detonating cord S in the finished capsule with explosive, possibly due to greater dilution of the displacing unit 30 to extend free from the packing material of the tip Z packaging sheath to the desired length. As detonating means in the capsule W from the explosive usually needs to be connected only on one side, it may be provided to separate free from packing material the tip of the packaging casing is not centered between pins C1, C2, and closer to one of the clips for the formation of sections of different length.

In the presented examples of the invention, the supply bag packaging sheath V impaled on the part of the filling pipe 20,120 side of the inlet. Of course, it is possible to form a tubular wrapping shell from a flat material, which is in the process of filling ulibaetsa around the filling pipe 20,120 and then touching food is determined as being the edges connected to the sleeve.

Stock detonating means may be further suitable drive mechanism. In this case, when, for example, detonating cord S has sufficient rigidity, it may, by a drive mechanism to move in the direction F of the filling with the popping. If the detonating means is pasty or powdery consistency, the drive mechanism is formed by an appropriate pump.

For uniform feeding of the detonating means of the drive mechanism of the stock detonating means may be properly synchronized with the transporting device for explosives.
