[0004] The method, particularly an automatic method, according to the present invention is designed, configured, or provided for operating, particularly automatically, a construction material pump and / or adhesive material pump for, particularly automatically, discharging construction material and / or adhesive material. The construction material pump and / or adhesive material pump includes or has at least one discharge cylinder and at least one discharge piston. The discharge cylinder is designed or configured, particularly for directly receiving and, particularly for directly discharging, the construction material and / or adhesive material. The discharge piston is movably arranged, particularly longitudinally, within the discharge cylinder to, particularly directly suck the construction material and / or adhesive material into the discharge cylinder and to, particularly directly discharge the sucked construction material and / or adhesive material from the discharge cylinder. The method includes or has the following steps: discharging, particularly automatically, the construction material and / or adhesive material by, particularly automatically and / or periodically moving the discharge piston for sucking and discharging the construction material and / or adhesive material; and detecting, particularly automatically, at least one position quantity, particularly the value of at least one position quantity, during the movement. The position quantity, in particular the value of the position quantity, characterizes the position, in particular the position value, of the delivery piston along its stroke in the delivery cylinder. At least one delivery quantity, in particular at least one value of the delivery quantity, is detected, in particular automatically, during the movement. The delivery quantity, in particular the value of the delivery quantity, is separate from the position quantity and characterizes the delivery, in particular the delivery value, of the construction material and / or sticky material by the construction material pump and / or sticky material pump. A temporal profile, in particular a subsequent movement of the delivery piston, in particular over time, is determined, in particular automatically determined, or set or adapted, in particular by combining at least the detected position quantity, in particular the detected value of the position quantity, with the detected delivery quantity, in particular the detected value of the delivery quantity.

Additionally or alternatively, the position quantity may characterize at least one end-of-stroke position of the delivery piston at at least one end of its stroke within the delivery cylinder.

[0009] "Along its stroke" may mean, in particular between end-of-stroke positions of the discharge piston, in particular at both ends of its stroke in the discharge cylinder. Additionally or alternatively, one end-of-stroke position may be an end-of-suction position and / or the other end-of-stroke position may in particular be an end-of-discharge position different from the end-of-suction position.

[0010] "Characterizing" can be called "representative of."

[0011] "Detection" can also be called "measurement."

[0012] The position quantity and the discharge quantity can be detected simultaneously, in particular continuously over time.

[0015] "Distinct" can mean that the position quantity and the discharge quantity do not need to or cannot have a fixed relationship to each other, especially over several travel strokes and / or travel periods, and / or can be independent of each other. In other words, "distinct" can mean that the discharge quantity does not need to or cannot be a fixed function of the position quantity, especially over several travel strokes and / or travel periods.

[0016] The position quantities and / or the discharge quantities can in particular in each case be combined without or with mathematical processing.

Additionally or alternatively, the delivery rate, in particular the delivery rate value, characterizes the excitation, in particular the excitation value, of at least one part of the construction material pump and / or sticky material pump, caused by the input of energy from the delivery piston to the construction material and / or sticky material. This makes it possible to determine a profile so that the pressure increase or decrease per unit time does not become too large. Additionally or alternatively, it is possible to prevent the excitation of the part from becoming too large. In particular, the delivery rate can be the pressure, in particular the driving pressure and / or high pressure, acting on the delivery piston, piston rod, or drive piston of the drive pump device, if any.

Additionally or alternatively, the discharge start position can be determined by combining the detected progression of the position quantities with the detected progression of the delivery quantity. Additionally or alternatively, the discharge start position can be determined as the position of the discharge piston at which the discharge volume, in particular the energy input and / or pressure and / or excitation (if any) and / or their increase over time, reaches or exceeds a limit value, in particular a predetermined limit value.

In particular, the profile can be determined such that a maximum, and therefore in particular an optimal, delivery volume is achieved. In particular, this can be achieved by maximally locating the discharge start position to the end of suction or stroke position and / or by a high degree of filling and a low duration.

This allows the discharge start position to be as close as possible to the suction end position or end of stroke position and / or the maximum filling level and / or the maximum delivery rate. In particular, when the discharge start position is no longer close to the suction end position or end of stroke position and / or the delivery rate and / or delivery rate no longer increases, the speed can be increased to the value of the preceding suction profile and / or the rest duration can be decreased to the value of the preceding suction profile.

The method comprises the following steps: discharging the construction material and / or adhesive material DS by moving the discharge pistons 3a, 3b to suck and discharge the construction material and / or adhesive material. During the movement, at least one position variable PGa, PGb is detected, in particular by means of the at least one displacement sensor device 4a, 4b. The position variable PGa, PGb characterizes the position POa, POb of the delivery piston 3a, 3b in the delivery cylinder 2a, 2b along the stroke HU. During the movement, at least one delivery quantity FG', FG" is detected, in particular by means of the at least one delivery sensor device 5', 5". The delivery quantity FG', FG" is separate from the position variable PGa, PGb and further characterizes the delivery of the construction material and / or sticky material DS by the construction material and / or sticky material pump 1. By combining the detected position variables PGa, PGb and the detected delivery quantities FG', FG" with each other, in particular by means of a determination device 6, a profile PR of the subsequent movement of the delivery piston 3a, 3b is determined. At least the subsequent movement is controlled in accordance with the determined profile PR, in particular by means of a control device 7.

[0044] In the illustrated embodiment, the construction material pump and / or sticky material pump 1 comprises at least one drive cylinder 10a, 10b, at least one drive piston 11a, 11b, and at least one piston rod 12a, 12b. The drive cylinders 10a, 10b are designed to receive, and in particular receive, hydraulic fluid HF. The drive pistons 11a, 11b are movably arranged within the drive cylinders 10a, 10b. The piston rods 12a, 12b are fixed to the drive pistons 11a, 11b so as to move in conjunction with the delivery pistons 3a, 3b.

[0045] Furthermore, in the illustrated example embodiment, the position quantities PGa, PGb are positions of the drive pistons 11a, 11b. In alternative example embodiments, the position quantities may in particular be positions of the delivery pistons or piston rods.

[0046] Furthermore, in the illustrated embodiment example, the construction material pump and / or viscous material pump 1 has at least one drive motor device 13 and at least one drive pump device 14 for moving, in particular displacing, the delivery pistons 3a, 3b.

[0047] More specifically, the drive motor device 13 is designed to drive or operate, in particular drives or operates, the drive pump device 14. Furthermore, the drive pump device 14 is designed to pump or transport hydraulic oil HF under pressure, in particular drive pressure p, thereby moving in particular the drive pistons 11 a, 11 b in the drive cylinders 10 a, 10 b, thereby moving the piston rods 12 a, 12 b and thereby moving the delivery pistons 3 a, 3 b.

[0048] Furthermore, the control device 7 is designed to control the drive motor device 13 and the drive pump device 14 to control the subsequent movement according to the determined profile, in particular as shown in FIG.

[0049] In the illustrated embodiment, the construction material pump and / or sticky material pump 1 has in particular exactly two delivery cylinders 2a, 2b, in particular exactly two delivery pistons 3a, 3b, in particular exactly two displacement sensor devices 4a, 4b, in particular exactly two drive cylinders 10a, 10b, in particular exactly two drive pistons 11a, 11b and in particular exactly two piston rods 12a, 12b. In an alternative embodiment, the construction material pump and / or sticky material pump has only one delivery cylinder, only one delivery piston and only one Displacement The sensor device may have, in particular, only one drive cylinder, only one drive piston and only one piston rod, or at least three delivery cylinders, at least three delivery pistons and at least three piston rods. Displacement It is possible to have a sensor device, in particular at least three drive cylinders, at least three drive pistons and at least three piston rods.

[0050] Furthermore, in the illustrated embodiment, the construction material pump and / or viscous material pump 1 comprises a oscillating pipe 15 for the hydraulic oil HF. The drive pump device 14 and the drive cylinders 10a, 10b form a drive circuit for the hydraulic oil HF by means of the oscillating pipe 15. In other words, the drive cylinders 10a, 10b are connected by the oscillating pipe 15 so that the hydraulic oil HF can flow, in particular between the drive cylinders 10a, 10b. The drive pistons 11a, 11b, and thus the piston rods 12a, 12b, and thus the delivery pistons 3a, 3b, are connected to one another by the oscillating pipe 15 so that they can move at least temporarily, in particular permanently, in particular in phase opposition, in particular 180° out of phase or in opposite directions.

[0051] In FIG. 1, the drive piston 11a, the piston rod 12a, and the discharge piston 3a move to the right as shown by the arrow. The hydraulic oil HF flows into the drive cylinder 11a as shown by the arrow. 10The fluid flows from the drive cylinder 10b through the oscillating pipe 15. This causes the drive piston 11b, and therefore the piston rod 12b, and therefore the delivery piston 3b, to move to the left, as shown by the arrows. When the delivery pistons 3a, 3b, and in particular the drive pistons 11a, 11b, reach their respective end-of-stroke positions POAE, POVE, they switch directions of movement. This causes the drive piston 11a, and therefore the piston rod 12a, and therefore the delivery piston 3a, to move to the left, while the drive piston 11b, and therefore the piston rod 12b, and therefore the delivery piston 3b, to move to the right.

[0052] In particular, the construction material pump and / or the viscous material pump can have a supply and / or a delivery opening for supplying and / or delivering hydraulic oil to the oscillating pipe, so that the drive piston, and thus the piston rod and thus the delivery piston, can be temporarily disconnected or decoupled from one another, in particular for independent movement.

[0053] Furthermore, the construction material pump and / or viscous material pump 1 has an adjustable pipe branching device 9 .

[0054] In the illustrated embodiment example, the construction material and / or adhesive material pump 1 has a discharge pipe 8' and a construction material and / or adhesive material supply 20. The pipe branching device 9 is designed to, in particular to, connect the discharge cylinders 2a, 2b with the discharge pipe 8' in one adjustment position or with the construction material and / or adhesive material supply 20 in the other adjustment position for the flow of the construction material and / or adhesive material DS.

[0055] In FIG. 1, the pipe branching device 9 connects the discharge cylinder 2a to the discharge pipe 8', and connects the discharge cylinder 2b to the construction material and / or adhesive material supply unit 20.

[0056] Furthermore, the discharge piston 3b sucks the construction material and / or adhesive material DS into the discharge cylinder 2b, in particular from the connected construction material and / or adhesive material supply 20. In particular, at the same time, the discharge piston 3a expels the sucked construction material and / or adhesive material DS from the discharge cylinder 2a, in particular into the connected discharge pipe 8'.

[0057] When the discharge pistons 3a, 3b reach their, in particular respective, end-of-stroke positions POAE, POVE, the pipe branching device 9 is adjusted, in particular by the control device 7, so as to connect the discharge cylinder 2b with the discharge pipe 8' and the discharge cylinder 2a with the building material and / or adhesive material supply 20. The discharge piston 3a thereby sucks the building material and / or adhesive material DS into the discharge cylinder 2a, in particular from the connected building material and / or adhesive material supply 20. In particular, at the same time, the discharge piston 3b expels the sucked building material and / or adhesive material DS from the discharge cylinder 2b, in particular into the connected discharge pipe 8'.

[0058] Furthermore, in the illustrated embodiment, the construction material pump and / or sticky material pump 1 is designed as a mobile construction material pump and / or sticky material pump, in particular as a construction material pump and / or sticky material pump vehicle, as shown in Figure 2.

[0059] Furthermore, the delivery volume FG' characterizes the input of energy from the delivery pistons 3a, 3b into the building material and / or adhesive material DS.

[0060] More specifically, the delivery rate FG' characterizes the pressure, in particular the driving pressure p, acting on the building material and / or adhesive material DS in the delivery cylinders 2a, 2b, as shown in FIG.

[0061] In the illustrated embodiment, the discharge sensor device 5' comprises a pressure sensor device.

[0062] Furthermore, the discharge quantity FG' characterizes the excitation AN of at least one part 8 of the construction material pump and / or sticky material pump 1 caused by the input of energy from the discharge pistons 3a, 3b to the construction material and / or sticky material DS, as shown in Figure 2.

[0063] In the illustrated embodiment, the discharge sensor arrangement 5' comprises an excitation sensor arrangement, in particular an acceleration sensor arrangement and / or a rotational speed sensor arrangement.

[0064] Furthermore, in the illustrated embodiment, one part 8 is in particular a discharge pipe 8' on a vehicle, and the other part 8 is in particular a discharge mast 8" equipped with an excitation sensor device of the discharge sensor device 5' at the tip of the discharge mast 8".

[0065] The method further comprises determining, in particular by a determination device 6, a discharge start position POVA at which the discharge pistons 3a, 3b start to discharge the sucked building material and / or sticky material DS from the discharge cylinders 2a, 2b, as shown in Figure 4, by combining the position quantities PGa, PGb detected during the discharge movement with the discharge quantity FG' detected during the discharge movement and characterizing the input of energy from the discharge pistons 3a, 3b to the building material and / or sticky material DS, and determining a profile PR based on the determined discharge start position POVA.

[0066] In the illustrated embodiment, the ejection start position POVA is determined by combining the position quantities PGa, PGb detected during ejection with the ejection volume FG' detected during ejection. In an alternative embodiment, the ejection start position can be determined by combining the position quantities detected during movement to the determined ejection start position with the ejection volume detected during movement to the determined ejection start position.

[0067] Furthermore, in the illustrated embodiment, the discharge start position POVA is determined as the position POa, POb of the discharge pistons 3a, 3b at which the discharge rate FG', in particular the pressure p, reaches or exceeds a limit value FG'limit, in particular plimit.

[0068] In FIG. 4, the discharge piston 3a moves, as indicated by the arrow, in particular to the right from the suction end position or discharge end position. The discharge piston 3a initially moves due to the vacuum or pushes away the building material and / or adhesive material DS that has not yet been sucked in. Therefore, the pressure p is low. As soon as the discharge piston 3a reaches the tip of the building material and / or adhesive material DS, the discharge piston 3a begins to push or press the building material and / or adhesive material DS into a cylindrical shape, but does not yet eject it from the discharge cylinder 2a. Therefore, the pressure p increases. As soon as the discharge piston 3a begins to push or press the building material and / or adhesive material DS into a cylindrical shape, the discharge piston 3a begins to eject the building material and / or adhesive material DS from the discharge cylinder 2a, in particular into the discharge pipe 8'. Therefore, the pressure p reaches or exceeds the limit value plimit. The discharge start position POVA is thus determined.

[0069] More specifically, the method comprises determining, in particular by means of a determination device 6, the degree of filling FD of the discharge cylinders 2a, 2b with building material and / or adhesive material DS based on the determined discharge start position POVA, as shown in Figure 3, and determining, in accordance with the determined degree of filling FD, a profile PR of the subsequent suction movements, in particular of the subsequent suction, as shown in Figure 6.

[0070] The method further comprises: determining, in particular by means of a determination device 6, a duration ZD of a preceding movement for suction, in particular of a preceding suction, which results in a determined discharge start position POVA and / or a determined filling degree FD, as shown in Figure 5; determining, in particular by means of a determination device 6, a delivery rate FM by combining the determined discharge start position POVA and / or the determined filling degree FD with the determined duration, as shown in Figure 3; and determining, based on the determined delivery rate FM, a profile PR of a subsequent movement for suction, in particular of a subsequent suction, as shown in Figure 6.

[0071] The method further comprises decreasing, in particular by the determination device 6, the speed v of the profile PR from the pre-suction as shown in Figure 5 to the post-suction as shown in Figure 6 and / or increasing the stationary duration SZD, until the discharge start position POVA no longer approaches the suction end or end-of-stroke position POAE and / or the filling degree FD and / or the delivery rate FM no longer increases. Additionally or alternatively, increasing, in particular by the determination device 6, the speed v of the profile PR from the pre-suction as shown in Figure 5 to the post-suction as shown in Figure 6 and / or decreasing the stationary duration SZD, until the discharge start position POVA moves away from the suction end or end-of-stroke position POAE and / or the filling degree FD and / or the delivery rate FM decreases.

[0072] 5 shows a standard profile SPR, in particular the leading movement, in particular the leading suction, of the delivery pistons 3a, 3b for the suction of a building material and / or adhesive material DS with a standard viscosity, in particular the standard acceleration and deceleration gradients. However, if the building material or adhesive material DS does not have the standard viscosity but has a different viscosity, the standard profile SPR is not optimal: the determined start position POVA of the delivery is not maximally close to the end position of the suction or end position POAE, the determined filling degree FD is not maximal, and / or the determined delivery volume FM is not maximal.

[0073] FIG. 6 shows a profile PR of the discharge pistons 3a, 3b, particularly the subsequent movement, particularly the subsequent suction, for suctioning the building material and / or adhesive material DS, determined in particular by repetition. The profile PR, in contrast to the standard profile SPR, has a high velocity v at the suction start position or start-of-stroke position or at the discharge end position or end-of-stroke position POVE. This allows a high initial suction vacuum to be generated quickly. Furthermore, the profile PR, in contrast to the standard profile SPR, has a high velocity v between the discharge end position or end-of-stroke position POVE and the suction end position or end-of-stroke position POAE or in the middle of the stroke HU. This allows a specifically determined low duration ZD. Furthermore, the profile PR, in contrast to the standard profile SPR, has a low velocity v and a high stationary duration SZD at the suction end position or end-of-stroke position POAE. This allows a high wake effect and therefore a minimal vacuum. This results in a particularly determined start of discharge position POVA, a particularly determined maximum filling degree FD, and / or a particularly determined maximum delivery volume FM that are maximally close to the end of suction or end of stroke position POAE.

[0074] Furthermore, the method comprises determining a profile PR of a subsequent movement, in particular from the suction end or end of stroke position POAE, in particular to a new discharge start position POVA, based on the determined discharge start position POVA, as shown in Figure 4. Controlling the subsequent movement to the discharge start position POAE according to the determined profile PR.

[0075] More specifically, the method comprises determining a profile PR such that the ejection pistons 3a, 3b accelerate, in particular from an end-of-suction or end-of-stroke position POAE, and then decelerate before a start-of-exhaust position POVA.

[0076] In other words, the profile PR has an increasing velocity v at the end of inspiration or end of stroke position POAE, followed by a decreasing velocity v before the beginning of exhaustion position POVA.

[0077] This allows the discharge pistons 3a, 3b to reach the discharge start position POVA in a minimum duration without moving too quickly relative to the building material and / or adhesive material DS.

[0078] The method further comprises determining a duration ZD of the preceding movement for suction and / or the determined subsequent movement for suction and / or the preceding movement to the discharge start position POVA and / or the determined subsequent movement to the discharge start position POVA, as shown in Fig. 3; determining a remaining duration RZD of the discharge, in particular the subsequent discharge, and / or the subsequent movement to the discharge end position or stroke end position POVE, by combining the determined duration ZD with a predetermined cycle duration and / or stroke duration HZD and / or a predetermined discharge volume FM, in particular by a determination device 6; determining a profile (PR) of the subsequent movement for discharge, in particular the subsequent discharge, in particular up to the discharge end position or stroke end position POVE, based on the determined remaining duration RZD; and controlling the subsequent movement for discharge, in particular the subsequent discharge, in accordance with the determined profile PR.

[0079] Furthermore, the method comprises: profiling a subsequent movement for ejection, in particular a subsequent ejection, in particular to an ejection end position or end-of-travel position POVE. PR, determining the position quantities PGa, PGb detected during the discharge movement, in particular during discharge, and the discharge quantity FG' detected during the discharge movement, in particular during discharge, which characterize the input of energy from the discharge pistons 3a, 3b to the construction material and / or sticky material DS, and in the illustrated embodiment characterize the excitation AN of at least one part 8 of the construction material pump and / or sticky material pump 1 caused by the input of energy from the discharge pistons 3a, 3b to the construction material and / or sticky material DS, by combining them so that the excitation AN of at least one part 8 of the construction material pump and / or sticky material pump 1 caused by the input of energy from the discharge pistons 3a, 3b to the construction material and / or sticky material DS is reduced or avoided. Controlling the subsequent discharge movements, in particular the subsequent discharges, in accordance with the determined profile PR.

[0080] 4 shows a profile PR determined in particular adaptively, in particular iteratively, of the discharge pistons 3a, 3b for the discharge, in particular for subsequent discharges, of the building material and / or adhesive material DS. The profile PR has or has an increase in speed v after the discharge start position POVA, followed by a decrease in speed v before the discharge end position or end-of-stroke position POVE. In other words, the method comprises determining the profile PR such that the discharge pistons 3a, 3b decelerate from the discharge start position POVA and subsequently before the discharge end position or end-of-stroke position POVE. This allows the remaining duration R ZD and thus the cycle duration and / or stroke duration HZD and / or the delivery rate FM and / or excitation AN of at least one portion 8 can be reduced or avoided.

[0081] Furthermore, the delivery rate FG" characterizes the adjusted position ST of the pipe branching device 9, as shown in FIGS.

[0082] In the illustrated embodiment, the discharge sensor device 5'' comprises an adjusted position sensor device.

[0083] Furthermore, in the illustrated embodiment, the construction material pump and / or viscous material pump 1 comprises an adjustment system 19 for adjusting the pipe branching device 9 .

[0084] Furthermore, in the illustrated embodiment, the discharge rate FG" is the adjustment position of the adjustment system 19. In an alternative embodiment, the discharge rate can be the adjustment position of the pipe branching device.

[0085] Furthermore, the control device 7 is designed to control, and in particular controls, a regulation system 19, as shown in FIG.

[0086] More specifically, the method comprises the following: a subsequent movement for ejection to an end of ejection or end of travel position POVE; and / or a subsequent movement for ejection to an end of ejection or end of travel position POVE. Place P OV E or determining a profile PR of the subsequent movements for suction from and / or to the suction end position or end of stroke position POAE and / or for discharge from the suction end position or end of stroke position POAE by combining the detected position quantities PGa, PGb with the detected discharge quantities FG″, which characterize the adjustment position ST of the pipe branching device 9, with one another in such a way that the subsequent movements of the discharge pistons 3 a, 3 b and in particular the subsequent adjustment of the pipe branching device 9 are synchronized; and controlling the subsequent movements to and / or from the discharge end position or end of stroke position POVE and / or to and / or from the suction end position or end of stroke position POAE in accordance with the determined profile PR.

[0087] 4 and 6 show adaptively, in particular iteratively determined, profiles PR of the subsequent movements of the delivery pistons 3a, 3b to and / or from the delivery end or end of stroke position POVE and / or to and / or from the suction end or end of stroke position POAE. The profiles PR are determined in such a way that the delivery pistons 3a, 3b are at or rest in the delivery end or end of stroke position POVE and / or the suction end or end of stroke position POVE just when the adjustment of the pipe branching device 9 begins and / or accelerate from this position just when the adjustment of the pipe branching device 9 ends.

[0088] In particular, the adjustment of the pipe branching device 9 is rather slow. Furthermore, the deceleration and / or acceleration of the delivery pistons 3a, 3b is rather slow. The adjustment of the pipe branching device 9 is therefore triggered, in particular by the control device 7, before the delivery pistons 3a, 3b are in or at rest in the end-of-discharge or end-of-stroke position POVE and / or the end-of-suction or end-of-stroke position. Furthermore, the acceleration of the delivery pistons 3a, 3b is therefore triggered, in particular by the control device 7, before the pipe branching device 9 is adjusted.

[0089] In particular, by detecting the position quantities PGa, PGb and the discharge quantity FG″ characterizing the adjusted position ST of the pipe branching device 9 after the adjustment of the pipe branching device 9 has been triggered in time and combining them, if the construction material and / or adhesive material DS has or has a viscosity other than the standard viscosity, the profile PR is determined in such a way that the discharge pistons 3a, 3b slow down more or less, so that the discharge pistons 3a, 3b are in or rest in the discharge end position or end of stroke position POVE and / or the suction end position or end of stroke position just when the adjustment of the pipe branching device 9 is started.

[0090] In particular, by detecting the position quantities PGa, PGb and the discharge quantity FG″ characterizing the adjustment position ST of the pipe branching device 9 after the acceleration of the discharge pistons 3a, 3b has been triggered in time and combining them, the profile PR is determined in such a way that, if the construction material and / or adhesive material DS has or has a viscosity other than the standard viscosity, the discharge pistons 3a, 3b accelerate more or less, so that the discharge pistons 3a, 3b accelerate from the discharge end position or end of stroke position POVE and / or the suction end position or end of stroke position POVE just when the adjustment of the pipe branching device 9 is finished.

[0091] This allows for low-wear and / or problem-free operation of the construction material pump and / or sticky material pump 1 and / or for as uninterrupted a discharge of the construction material and / or sticky material DS by the construction material pump and / or sticky material pump 1 as possible.

[0092] The method further comprises the step of selecting an optimization goal OZ from a group of a plurality of selectable optimization goals OZ, and determining the profile PR in accordance with the selected optimization goal OZ, in particular such that the selected optimization goal OZ is achieved.

[0093] In the illustrated embodiment, as shown in FIG. 1, the construction material pump and / or viscous material pump 1 has a control element 30 that is operated by a user to select the optimization target OZ.

[0094] Furthermore, the at least one displacement sensor device 4a, 4b, the at least one discharge sensor device 5', 5", the determination device 6 and the control device 7, in particular the drive motor device 13, the drive pump device 14, the regulating system 19 and the control element 30, each have in particular one signal connection, in particular an electrical one, which is shown in dotted lines in FIG. 1.
