Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a survey blockage conveyor having at least one discharge station, which is divided into sections and can be driven, and is equipped with a conveying member for holding the survey. Each section is driven by an intermediate roller driven by a constantly circulating tension member, which intermediate roller is driven by a detector that can be inserted into the path of movement of the survey. Relating to a type of thing that is adapted to be moved from position to idle position.

In a blocking conveyor of the type described above, which is known from German Patent Application DE 2,856,486, the surveying material is conveyed along the blocking conveyor and is optionally removed on one side by a special removal station. It is designed to be ejected towards the target. As a separate unit, this removal station requires not only technical outlay but also its own section area, which cannot be used as a blockage space. Furthermore, in the belt conveyor switch known from German Utility Model Registration No. 8017695, a device is provided with a switch conveyor belt which can be pivoted about a horizontal axis at the end of the conveyor belt. By means of this belt, the measurements can be selectively transferred to the conveyor belt on three sides or below, where the conveyance is to be carried out. This point conveyor (Vl) has its own drive and is designed as a continuously operating device, which is not suitable for blocking purposes. This device therefore also requires its own space, which cannot be used as a blockage space. The known bag MU for discharging the measurements from a continuously moving conveyor belt is technically expensive for space reasons and reduces the number of stoppers. Therefore, only a relatively small number of discharge stations can be arranged over the entire length of the blocking conveyor in order not to significantly reduce the blocking volume.

SUMMARY OF THE INVENTION It is therefore an object of the invention to provide a blocking conveyor with a large blocking volume and a large number of discharge stations, which can be discharged at high speeds.

According to the present invention, the second problem is solved by the fact that the section of the conveying member serving as the ejection station is supported in a section frame that is pivotable about a pivot axis arranged parallel to the conveying plane. , this section frame is movable by means of an auxiliary force into an oblique pivoting position in which it is to be connected to a conveying element arranged at an offset in height, but the drive connection between the section frame and the tension paulownia is permanent. It is solved by being made or always configurable.

The advantage of the invention is, inter alia, that the entire length of the blocking conveyor can be used for survey blocking and that each section can be formed at the same time as a discharge station. The amount of blockage therefore corresponds to that of a typical blockage conveyor, which provides a possible means of discharge at each blockage point. Each discharge station thus does not require its own space, so that its entire conveying length can be used as a blocking space, as in a conventional, simple blocking conveyor. Furthermore, the turning movements necessary for the discharge operation can be carried out in a very short time, so that the conveyance on the blocking conveyor can be carried out at the speeds customary heretofore. That is, the blocking conveyor according to the present invention integrates the blocking function and the discharging function without increasing the required space.

This blocking conveyor simultaneously fulfills blocking and distribution functions.

Advantageous embodiments of the invention are defined in claims 2 to 7.
As stated in section.

The invention will now be explained with reference to the illustrated embodiment.

As shown in FIGS. 1 to 6, the blocking conveyor has a conveyor member 2 as a conveyor belt between parallel longitudinal frames 1 and 1'. This conveying member 2 has a plurality of sections 5. arranged in series. 5', 5'', and each section has an intermediate roller 1.
4 are driven independently of each other by a recirculating tension member 4, for example a chain.

This tension member 4 is driven from left to right in FIG. 1 by a motor, not shown.

Each section 5.5', 5'' is supported in a section frame 6, which section frame 6
A deflection roller 7 is rotatably disposed at both ends of the conveyance member 2, and a belt-shaped conveying member 2 is wound around the deflection roller 7. Depending on the respective construction of the conveyor element 2, a support element 8 is arranged between each deflection roller 7 for receiving the pressure exerted by the measurement to be conveyed. For example, in the case of a conveyance direction from left to right according to arrow 9, the pivot shaft 10 is pivoted to the longitudinal frames 1 and 1' at the left end of the section frame 6 opposite to the conveyance direction 9 in question. 1, so that the section frame 6 can be pivoted upwards and/or downwards from the conveying plane of the blocking conveyor (illustrated in phantom in FIG. 1). In its respective upward and/or downward pivoting position, a distribution track 11. is assigned to each section 5.5', 5'' as a further conveying member and arranged at right angles to the conveying direction 9. 11' is arranged, the distribution track being arbitrarily configurable and guided directly or indirectly towards a predetermined target location. Advantageously, the distribution track includes at least each section 5. 5'. , 5
In the receiving range from 5.
It is selectively ejected upward or downward by the pivoting movement of ``, and is guided in advance toward a predetermined target position.

Furthermore, as is clear from FIGS. 4 to 7, the deflection roller γ of each section 5.5', 5" is rotatably supported on a shaft 12-F in the section frame 6. A shaft 12' is arranged at the inlet end of the shaft 12' in the form of a shaft guided through the section framework, on the outside of which a drive gear 13, which in the illustrated example is designed as a gear wheel, is arranged. Intermediate roller 1
A suitable corresponding gear 14' of 4 is in driving connection with the aforementioned drive gear 13 in its drive position. This corresponding gear 14' is fixedly connected to the drive wheel 14' and is rotatably supported together with the drive wheel in the housing 15. This casing 15 has a pivot shaft 1 fixed to the section frame 6 almost vertically above the rotation shaft of the corresponding gear 14'.
The intermediate loaf 14 is supported so as to be able to reciprocate (oscillate) about the rotor 6, thereby allowing the intermediate loaf 14 to pivot in the clockwise direction from the drive position shown in the figure to an idling position. 'il 14' is disengaged from drive gear 13. The drive wheel 14'' is driven by the tension element 4 and is preferably always in a driving connection with this tension element.If the tension element 4 is designed as a chain, the drive wheel 14'' is correspondingly driven by a chain wheel. The chain wheel is always in mesh with the chain of the tension member 4, even in its idle position.A support profile 17 is also provided, which is fixed to the longitudinal frame 1, to support the tension member 4. There is.

For controlling the intermediate roller 14, a detector 18 is configured, for example, as a roller and is supported on both sides in detector levers 19.
The detector lever 19 is pivotable about a shaft 20 arranged at the exit end of the section frame 6 perpendicularly to the transport plane of the survey on the transport member 2. The detector 18 normally projects into the transport plane of the survey and is pushed downward by this survey to a switching position located outside the plane (shown in dashed lines in FIG. 4). In this switching position, the axis 18' of the detector 18 rests on the stop 21 of the section frame 6, and the detector serves as a support for the sliding survey on the section frame 6. The detector lever 19 located on the side of the intermediate roller 14 has an arm 19' projecting downward, and a switching rod 23 is pivotally attached to the lower part of the core arm 19' through an elongated hole 22. The upwardly bent opposite end 23' of the switching rod 23 is pivotally connected to the upper end of the double lever 24. This double lever 24 is coaxial to the axis of the corresponding gear 14' and has the same section 5.5'.

It is rotatably supported by a casing 15 of a 5" intermediate roller 14. A switching rod 25 is pivotally connected to the lower end of the double lever 24, and the other end of the switching rod P25 is Section 5 located one place ahead
, 5', arm 19' of the detector lever 19 of 5〃
It is connected to the. In order to prevent the control operation from being disturbed when the section frame 6 is rotated, this switching rod 25 is formed in two parts and has a hinge 26 at its separation point, which hinge 26 is connected to the pivot axis 10. It is arranged substantially coaxially on the holding arm 27. This holding arm 27 is pivotally connected to an adjustment arm 28 that holds the pivot shaft 10, and the upper part of the single-core adjustment arm 28 is fixed to the section frame 6 by bridging the intermediate roller 14.

An adjustment cylinder 29 supported on the longitudinal frame 1 of the holder 30 is connected to the downwardly projecting extension 28' of the adjustment arm 28. If the section frame 6 is to be pivoted in only one direction, either upward or downward, the final position of both can be adjusted using the adjustment cylinder 290.
It can be defined by travel distance. If, on the other hand, it is necessary to be able to selectively swivel upwards or downwards, a rest member 31 as shown in FIG. 4, for example, would be provided. In this case, at the lower end of the extension 28',
A roof-shaped stop 32 projecting downwards is arranged, and in the conveying position, adjusting wedge elements 33, 33' abut on both sides of this stop 32, each of which can be adjusted with the aid of an auxiliary force, for example by an adjusting cylinder. The section frame 6 can be adjusted downwardly from the locking position shown to the release position, and the section frame 6 can be pivoted in one direction or the other by U° (shown in chain lines).

When the surveys are transported on the conveyor member 2 and are to be blocked or stored, each survey is stopped one by one by switching off its 13 degree section 5.5', 5''. When the detector 18 is pushed down,
Switching rod 25 of double lever 24 of intermediate roller 14
, the section 5.5' or 5" located at the rear against the conveying direction is moved in a clockwise direction, so that the elongated hole 22 is moved to the right by the sliding of the switching rod 23 into its other end position. The detector 18 of this section 5.5', 5'' is also pushed down in the same way.
The switching rod 23 is pushed to the left by the switching movement in the clockwise direction, since the switching rod 25 remains stationary in its switching position and the intermediate roller 14 is moved clockwise into the idle position. The drive is then interrupted and remains stopped in the survey. On the other hand, section 5.5' is located one section ahead in the conveying direction.

When the 5" detector 18 is released, the intermediate roller 14 of the section 5.5", 5" located behind it is returned to the working position by the tensioning force of the tensioning member 4 or by an additional spring force. It can be rotated. The driving connection is then formed again and the surveying material located on the transport member 2 is transported further.

In the area of each section 5.5', 5", a reading station 35 is arranged above or beside it, by means of which the code placed on the survey is determined in its respective angular position with respect to the conveying direction. When it is determined that the survey of the affiliated CEF should be discharged, the relevant connection will be determined with the start of continuous transportation. Each section 5.5', 5'' is pivoted upwards or downwards. Section 5. 5', 5' may additionally be monitored by a photoelectric device 34 arranged at the outlet end, so that the pivoting of the section frame 6 takes place in the shortest possible time and thus Snow-free survey conveyance at normal speeds can be achieved.

According to a further embodiment of the invention, which is shown in FIG. are guided through. According to a further embodiment shown in FIG. 9, the conveying member 2 consists of a plurality of holding rollers 2', which hold when an intermediate loaf 14 (not shown) is in the working position. , are adapted to be driven together by one common circulating tension member, such as a chain or a Pel Y.
