Output device for staples lined up like a belt on stapling devices or machines.

The innovation relates to an output device on stapling devices or machines for staples lined up in a belt-like manner Staples having a storage chamber and a feed mechanism and in operative connection therewith stands, and aims to improve the puncture ability of such stapling machines.

In the case of output devices for staples lined up in a belt-like manner, it is necessary to have a feed mechanism to provide, which the staples one after the other and continuously feeds a driving mechanism in which the staples are separated from the belt, reshaped and driven.

When feeding such staples from a storage chamber into the driving mechanism must. necessarily a device can be provided to prevent undesired backward movement of the belt. If you have this Namely, does not avoid backward movement, the belt will warp or throw up, so that no proper and proper feeding is possible and the device on which the output device is arranged is not working properly functions.

Known devices for preventing such backward movement of the belt are normally within the driving device itself arranged. The consequence of this training and wear and tear is that these devices often need to be replaced. Such an exchange

means sending in, at least the removal of the entire driving device for the purpose of overhaul, whereby the entire stapler cannot be used for the duration of this overhaul.

The object of the innovation is to eliminate these disadvantages and to create a device for avoiding the backward movement of the belt, which is easily exchangeable and only extremely short downtimes of the entire apparatus when exchanging has the consequence.

This object is achieved by the innovation in that the output device an adjacent to the Heftklairrnergurt, whose return movement includes a control or control element. The device for preventing the backward movement of the staple belt is thus located within the dispensing device self; however, this output device is normally designed so that it only has a relatively short service life and either after the staples stored in it have been used up or, in the extreme case, after five to ten times Replacing the staple rolls is thrown away. This means that the device also needs to prevent the return movement of the clip belt only have a relatively short service life, because this device is light after its wear during the exchange of the output device can be exchanged without the driving device is impaired in any way. Even in the event that the backward movement prevention device Should any dispensing device fail, it is easy for the operator, just one Second output device, of which there is usually always enough available and kept in stock, should be used and therefore to keep the failure of the device practically zero, i.e. continuous work with the device to ensure.

According to a preferred form of innovation thanks If the control or control element consists of a spring element, which is particularly suitable + · to carry out the desired puncture. This control element or spring member is expediently easily accessible, quickly releasable and be arranged interchangeably in the output device without difficulty.

Preferably, the spring member can be formed substantially U-shaped and at one end one against the The staple belt has abDieoung fitting, while possibly daa the other, opposite end of the spring member can have an additional U-shaped part, which also rests against the staple belt and with the feed mechanism is in operative connection. Such a form of training is particularly easy to manufacture structurally and has the necessary elasticity, while on the other hand the The cost of materials is quite low, which in turn means low manufacturing costs. - Of course, it can also be useful the other, opposite end of the spring member is bent ε, advantageously the two bent ends of the The spring link should be bent in the same direction.

The innovation is explained in more detail below with reference to the exemplary embodiments shown in the schematic drawing explained. Show it

7 shows a perspective detailed view of the control element.

In the drawing one recognizes an output device 11, which has a housing 12 with a lower part 13 and an upper part 14, the lower part 13 with the upper part 14 by means of a hinge can be connected.

A carrier part 16 is located on the lower part 13 of the housing 12 attached, with a plurality of forwards, i.e. in the dispensing direction, projections or lugs 17 which in turn carry a plurality of feed members 18. A staple belt 19 is housed in the housing 12 and therein specially carried by a pin 20.

The feed members 18 are provided with a control or control element 21, which is designed as a U-shaped spring member, connected, this spring member having a bend 22 on its has a second bend 23 on one side and on the opposite side.

The bend 22 is expediently designed in two parts or in the form of a fork and lies against the staple belt 19 as can be seen from FIG. 5.

The second, opposite displacement 23 of the spring member 21 is also arranged so that it is against the staple belt 19 is present.

The mode of operation of the new facility is as follows:

-5-

In order to insert a staple belt 19 into the actual stapling device, the feed members 18 exerted pressure causing them to move backwards. As a result, the feed members 18 exert a pressure on the Spring member 21 from, the release of this pressure leads to the fact that the feed members 18, the staples or the Move the staple belt 19 forward, i.e. towards the driving device.

On the other hand, the bend 22 of the spring member 21 prevents backward movement of the staple belt 19, since the Spring member 21 is compressed and thus has an increased energy content, so that the spring force against the undesired Return movement of the clamps is directed. When the tension of the spring 21 is released, the second pushes Bend 23 the staple belt 19 to the front, this can then easily move past the part 22.
