BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for selecting the priority of moving piece pieces in a segmented production line, comprising a plurality of feed conveyors and one collecting conveyor.

Due to the stated composition of the production line and the very general operating mode of the independent feeding of piece pieces by feeding conveyors to the collecting conveyor and the movement on this collecting conveyor, there is no solution to the problem of automatic collision prevention of these pieces and effective blocking of their movements. only to the extent necessary.

These deficiencies are solved in the field of use of the device for selecting the priority in the movement of piece goods in the segmented production line according to the invention, consisting of two cross conveyors and one collecting conveyor connected by means of cross elements. limit encoder, there is a single default encoder at the beginning of the cross element, at the end of the cross element there is a single encoder and a stop, these encoders are connected to the inputs of the additional logic network so that the individual encoder is connected to an input of a single gate whose output is connected to an individual output of this logical network, a single default position sensor is connected to a first recording input of a single memory circuit, the second recording input t since the memory circuit is connected to another initial position sensor, the individual end position sensor is connected to the lubrication input of the individual memory circuit, the output of which is connected to the control input of the single gate.

The benefit of the device for selecting the priority in the movement of piece articles in the articulated production line according to the invention is auto2

224 080 The math choice of the advantage and the prevention of mechanical collision of the piece objects during their irregular and independent movement on the conveyor of the sacked production line.

In the exemplary embodiment, the device for selecting the priority of the movement of piece objects in a segmented production line is shown in the drawing, where Fig. 1 schematically shows the location of the sensors in the segment of the segmented production line, and Fig. 2 shows the connection of these sensors to an additional logical network .

Fig. 1 shows a single cross conveyor L _n connected to a collecting conveyor D by means of an individual cross element ® _n , also showing a second cross conveyor L _{n + 1} connected to a collecting conveyor D by means of a second cross element Ε _{β +} ι * For example, roller conveyors are provided to allow the movement of the piece articles K K in the transverse direction S S or the piece articles Kg ^{in the} longitudinal direction Sg. In this case, it is assumed that the collecting conveyor D is equipped with drive rollers, for example with a chain drive, carrying the pieces Kg in the longitudinal direction Sg.

The cross-member 33 _β , E _{n +} ^ is considered to be a separating member of the piece objects K ^, Kg from the pickup roller D, with a vertical movement, for example as a set of rollers parallel to the rollers L _n , L _{n + 1} . mounted on a separate structure, mechanically operated, with two extreme positions - below and above the conveyor path

Fig. 1 shows dashed significant levels for the location of the position sensors. At the limit level at the end of the individual cross conveyor I » _n there is an individual limit sensor C _n .

In the initial level at the beginning of the individual cross element E there is a single default position sensor A_. At the end Π _{e — l} level at the end of the individual cross-element E _n is one

224 060 Position encoder B ^.

Similarly, at the limit level at the end of the second cross conveyor L _{n + 1} there is a second limit sensor C _{n + 1 of the} position. In the default level at the beginning of the second cross element, the second default encoder A is _{n + 1} . At the end level at the end of the second cross element E _{n + 1, the} second end position sensor B * _{1 is} provided. The designation of these significant levels refers to the anticipated direction of movement S ^, Sg of the piece articles K ^, Kg.

At the interface of the end of the individual cross-element E _n there is a single stop R _n , at the interface of the end of another cross-element there is a second stop R * ^. A mechanical element for catching the piece when reaching the end level, for example designed as a two-position remote control member, preferably coupled with a switch set to switch on when the piece is moved to the stop, is considered as a stop. A specific form of this stop is a pneumatic cylinder controlled by an electromagnetic slide *

To capture the piece Kg by detaching it from the pick-up rollers of the collecting conveyor D when it reaches the second stop is solved by lifting the second cross element Ε _ή +1 ^from closing the switch coupled with the second stop R _{n + 1} ·

FIG. 1 further shows two piece pieces K1,

Kg, the first piece object K ^ on the individual cross conveyor L _n in the position before reaching the limit level of the individual limit sensor 0 _n and the second piece object Kg on the collecting conveyor D in the position reaching the initial level of the next initial sensor ^A n + 1 *

At the point in time of reaching the second piece object Kg of this initial level of the second position sensor A1, it is compared

224 060 occupation or non-occupancy of a single section representing a single cross element E _n with corresponding sensors and other elements marked with index n, and occupation or non-occupancy state of another section representing a second cross element β with respective sensors and other elements marked with the index n + 1 · It is clear that the first piece K ^ reaches the limit level of the individual limit sensor C _n only after the second piece Kg has reached the initial level of the second sensor A _{n +} ^. by passing the first piece piece K ^ from the individual cross conveyor L _n through the individual cross element E _n to the collecting conveyor D ·

This advantage lasts up to the transition and exit of the second piece piece Kg of the end level of the individual end position sensor B _n as it moves along the collecting conveyor D in the longitudinal direction Sg ·

The achievement of the first piece object K ^ of the limit level of the individual limit sensor C _n causes, with respect to the aforementioned advantage of the second piece object Kg, the first piece object K ^ to cease and remain in this position until this priority has ended.

The subsequent transfer of the first piece from the individual cross conveyor I » _n to the collecting conveyor D takes place by means of a single cross element E _n in the extended position above the path of the collecting conveyor D. The level of this extended position is preferably at the path level of the individual cross conveyor L *.

The actual movement is carried out manually, by means of a special pneumatic puller or another, e.g.

224 060 hunt with linear motion result ·

Upon completion of this displacement, the individual cross-element E _n is retracted into the retracted position below the path of the collecting conveyor D, and the first piece object K 'is moved in the longitudinal direction Sg by the driving movement of the rollers of this collecting conveyor.

When reaching the first piece object K-threshold levels of the individual limit sensor C _n positions before reaching a second piece object Kg initial level of the second initial sensors and _n + positioning a first piece item K ^ forces expediently prefer the transition from a single transverse conveyors _»n via single a cross element E _n on the collecting conveyor D before moving the second piece object Kg on the collecting conveyor D beyond the end level of the second end position sensor B _{n + 1 of} the longitudinal direction Sg.

This advantage lasts until the transition and exit of the first piece piece K1 of the end level of the individual end position sensor B _n as it moves along the collecting conveyor D in the longitudinal direction

5 ·

With such a suitably enforced advantage of the first piece K ^, when the second piece Kg reaches the initial level of the second initial position sensor A _{n + 1,} the second detent extends to a catch position above the level of the collector conveyor D. end position sensor B _{n +} ^ of the position, or approaching this second stop R _{n +} ^, the second cross element extends above the level of the collecting conveyor path JD and causes the piece to separate from the rollers of the collecting conveyor and only to stop ·

224 060

At the end of the aforementioned advantage of the first piece, the second cross element is brought back into the retracted position below the level of the collecting conveyor D and the second piece Kg is moved in the longitudinal direction Sg by the roller movement of the collecting conveyor.

In doing so, the second stop guarantees by its mechanical design a relatively precise stop of the second piece Kg by approaching the stop, which guarantees a symmetrical positioning of the piece on the second cross element E _{n + 1} during the priority of the first piece ·

The above selection of priority is easily automated with the aforementioned position sensors and additional logic network ₀

In FIG. 2, a single position limit sensor C _{n is} connected to an input h _{n of a} single gate H _n , the output of which is connected to an individual output of the additional logical network. A single default position sensor A _n is connected to a first recording input ^ from a "single memory path P". A second recording input ² from _{n of} this memory circuit is connected to another default position sensor Α _{β + 1} . The individual end position sensor B _n is connected to the lubrication input m _{n of the} individual memory circuit P _n , whose output is connected to the control input χ _{η of the} single gate · n

Another limit position sensor C _{a + 1} is connected to the input ^h n + l of the ^{other gate H} n + i> and the ^eil <> ^ž output is connected to another output Xn + j of the additional logic network. The next default An + 1 position sensor is connected to the first recording input ¹ n + 1 dal-.1 —- K of the memory circuit P _{n + 1} · The second recording input from _{n + 1 of} this memory circuit is connected to an additional one in the default order position sensor. Second end position sensor B _{n +} j

224 060 is connected to the lubrication input m _{Q + 1 of the} second memory circuit ^P n + 1 * ^whose «3® is connected to the control input X _{n + 1 of the} second gate H _{n +} ^ ·

The state of enforced priority of the second piece conveyor Kg is realized by means of an additional logical network so that at the time of reaching this second piece object of the second level sensor A _{Q + 1} position causes the output signal of this sensor ^JIL by acting on the second recording input ζ _β the memory circuit P _n into a busy state, where the output signal of this memory circuit acting on the control input causes a single gate H _n to be blocked for a signal from a single position limit sensor C _n to an individual output of the additional logical network; excitation of the second memory circuit Pto the state occupied in the next section, where the output signal of this memory circuit acting on control input X _{n +} j causes blocking of the second gate P ^ro signal from the second limit sensor ^C n + 1 position at the next output p additional logical networks ·

It is obvious that the occupancy status of the next period lasts until switch and leaving the second piece object Kg end level of the second end position sensor, and by changing the output signal of this sensor acting on the resetting input ^m n + l ^druhél10 memory circuit condition contained in an individual of the segment lasts until the transition and exit of this second piece of the end level of the individual end position sensor B _n by changing the level of the output signal of this sensor acting on the lubrication input of the individual memory circuit P _n ·

It is assumed that the resulting behavior of moving δ

The 224 060 segment elements determine the signals at the outputs of the additional logical network.

For example, the signal at the individual output X & of the auxiliary logic network conditions the transfer of the first piece from the individual feed conveyor I » _n to the collecting conveyor D and at the same time extends the second stop a about the gripping position above the track of the collecting conveyor D. network.

The forced priority state of the first piece is realized by means of an additional logical network such that the signal at the individual output X _{n of} the additional logical network extends the second stop R _{n + 1} to the aforementioned catching position.

The device for selecting the priority in the movement of piece articles in the articulated production line according to the invention finds application in the solution of control discrete automata in the production lines of foundries with casting capacity divided into several casting conveyors.
