Description
GA~RBAG13 TRUCR
BACKGROUND OF THE INVENTION
Fleld of the Invention This invention refers to a garbage truck with a garbage inlet openlng leading into a ~ipping section, with a press means being reciprocably movable in th0 tipping section and guided along the side walls thereof, said press means propelling the discharged garbage through an opening into a receptacle, prefer~
ably into a container designed as an interchangeable container with detachable couplings, and with at least one lateral arm or wall reinforcing the side walls of the tipping section and being arranged above the press means.
Description of Prior Art A garba~e trucX of said kind is aiready kno~n e.g. fl~m the European Patent Publication EP O 163 859 A2. In this garbage truck, the garbage inlet opening is located in the front section of the vehicle, partially above the cab and partially between this cab and the container in the area behind and above the cab, wherein a lifting and tipping device picks up the garbage cans for emptying them into the garbaga inlet opening. The press means being guided in the tipping section is reciprocably moved by hydraulic piston cylinder units such that said press means propels the garbage discharged into the gar~age inlet opPning through an inlet opening provided with a sealing means into the container~ Therein the press means can be moved into the contain-er in the manner as shown in Fig. 2 of the documen~ EP O 163 859 A2 through the sealable inlet opening of the container so that the garbage i~ comprassed in the container with increasing fill-ing thereof. Since the press means propelling the garbaga from the tipping section to the container exercises considera~le pres-sure forces in the tipping section with increasing compression of the garbage, the side wall~ o the tlppirlg sec~ion are rein-forced by a lateral arm arranged above the guidance for the press means. Instead of a lat~ral arm, also wall o~ the inlet opening covering the tipping sectlon can be used for reinforcing the walls of the tipping section.
When obiects protruding over the upper edge of the press means are discharged into the tipping section, e.g. logs or iron girders or the lika, said obJects can get Jammed between the press means and the lateral arm or wall parts, in particular if they are in an oblique position, which can result in deformat-ion~ and ~amages of the lateral arms or wall parts. Obligue or tilted parts can also get jammed between the press means and the upper edge of the single open~ny of the container so that the container is damaged and a sealing thereof might be impossible.
Summary of the Inventlon Therefore it is an object of the invention to provide a safety msans for a garbage ~ruck of the kind mentioned hereinbe-fore, which prevents damages of the garbage truck caused by ob-jects discharged in the tipping sectlon and getting ~ammed bet-ween the press means and parts of the tippiny section or the con tainer.
This problem is solved according to the invention for a garbage truck of the generic type by the fact that in the upper section of th~ open push-out side of the tipping section a sens-ing element is arranged which gen~rates a sigral when there ls a Jam or when there are tilted or bulky obJacts, said signal stopp-ing the travel of the press means or changing the latter's drive to a reverse motion. Thus, the sensing element provided accord-ing to the invention prevents that bulky, protruding or obllqua obJects aan get Jammed in such a way between the press mean~ and mounting part~ of the tipping sect~on or of the garbage 1nlet opening or of tha container that damages occur. Advantageously, when there is a react~on of the sensing alement, the drlve ~or the travel of tha press mean~ is immediately changed to reverse motion so that due to a corr~sponding indlcation, th~ driver or the operator is informed that tilted or Jammed parts lle :Ln the tlpping ~ection which must be removed therefrom.
When discharging bulky or longer part~ in the garbage in-let opening, it may happen that these objects get ~ammed therein or get tilted and do not reach the tipping section at all in which they could be seized by the press means. Therefore, in a further development of the invention it is provided that in the upper section of the open push-out ~ide of the tipping section levers or clawa being pivotable by a drive are arranged for loos-ening ob~ects possibly tiltad or Jammed in the garbage inlet opening from -the wall~ and pressing them into the tipping sect-ion ~uch that they can be seized therein by the press means.
Said pivotabi2 levers or claws are advantageously deslgn-ed such that after retrac~ing the press means they can still press ob~ects protruding out of ~he garbage inlet opening of the container thereinto so that the container can be sealed. Such ob;ects protruding over th~ garbage inlet opening can occur in partiaular when these objects got jammed between the slide-like press means and the edges of the garbage inlet opening so that these ob~ects are carried along during the backward movement of the pres~ means and then are retra~ted from the container.
It i8 advantageous that the sensing element consists of at least one pro~ection mounted on a shaft. The shaft can be car-ried above the open push-out side of the tipp~ng section in the walls thereof~ When the sensing el~men-t detelrts tilted or ~ammed ob~ects, it exercises a torque onto the shaft, and a switch or the like is ac~uated on rotatlon of tha shaft, whlch caus~s the ~ignal to be triggered.
In addition thereto, at the shat also at least one claw can be fixed so that the sha~t can be rotated by a 3pecial drive means in order to break up a jam by means of the claw or to press tilted objects into the tipping section or the garbage in-let opening of the container.
Advantageously, the sensing elem~nt and/or the claw are designed in the shape of a strip. Thus they are able to monitor the entire width of the tipping section or to intervene along the entire width thereof.
According to a particularly advantageous development the shaft is provided in a crank-liks manner with a lever upon the free end of which a hydraulic pressurs piston cylinder unit act~. Sald pressure piston cylinder uni t can be operated as sens-ing element or as a drive. When no pressure is applied to the piston cylinder unit for the rotation of the shaft, the pressure in the cylinder $s increased through the piston, if a torque is exercised on the shaft through the sensiny element. Said incre-ass in pressure can be detected by a pressure feeler or pressure switch which then triggers control signals and/or alarm signals.
When the levers or claws are to be opsrated as sllde ele-ments, the piston cylinder unit can be supplied with pressure in a u~ual way for the rotation of the shaft.
Embodiments of th~ invention will now be described in the following with reference to the drawings.

Detailed Description of Preferred Embodiments The garbage truck 1 as shown in Fig. 1 and 2 corresponds in its basic structure to the garbage truck described in the pub-lication EP-O 163 859 A2, so that on the whole reference is made to said document for the detailed description of the garbage truck .
A container 3 designed as interohangeable receptacle i5 detachably mounted on the vehicle ~rame 2, the container b~31ng provided with a sealable garbage lnlet opening at its side ~ac-ing the cab.
Below the garbage inlat opening 4, there t~ the tipping section 5 to which the garbage lnlat op~nin~ 4 leads ln a funnel shape. In tha tipping sectio~ 5, being of rsotangular shap~ in the cros~-section, the slide-lik~ pra~s means3 6 i~ guided for a reciprocable movement. The pres~ means 6 comprise~ a rectangu-lar, slid~-like front part 7 and a support ~heet metal 8 being connected therewith by forming a right angle. ~he pre~s means 6 is provided with lateral guiding rails 9 which are guided in khe guiding grooves 10 formed in the side walls of the tipping ~ect-ion 5 by U-shaped beams recessed therein.
For the reciprocable movement of the press means, at the back side of the front slide part 7 thereof, the piston rods are linked by intersecting hydraulic cylinders 12, 13, the cylinders of which are linked to the rearward side wall of the tipping section facing the càb. In that, the tipping section and the de-sign of the press means and of the hydraulic cylinder for tha moving thereof correspond to the embodiment described on the bas-i~ of Fig. 6 to 8 according $o publication EP 0 163 859 A2, the pis~on rods, however, being directly linked to the front press mean~ and no toggle lever linkag~ bein~ used.
Above the guidings 10 formed by the U-shaped beams, the side walls 15, 16 of the tipping section 5 are reinforced by a transversely extending lateral ar~ ~not shown) or by the trans-versely extending wall of the garbage inlet opening 4.
Close above the path of movement of tha ~ress means 6, in the slde walls 15, 16 of the tipping section or in carriers 17, 18 connected therewith, a shaft 19 is carrled with its ~ha~t ~ournals rising above the carrier 17 and a lever 20 being mount-ed crank-like thereon, to the free end of which the connectlon rod of a hydraulic cylinder 22 is linked which i~ flexibly Join-ed by the flex~ble hinge 23 with the ~ide wa:L1 15 of the tippingsection 5 or another part fixedly arranged a-t the vehicle.
Sha~t 19 is conneated with a ~trip 24 having an approxima-tely nose~ e proile and with a ~trip 25 constltutlng a sllde and forming an o~tuse angle therewlth. In thle represented posit-ion corresponding to the no~mal tipplng operiation, the nose-like strip 24 lies close above the upper edge of the press means 6 and ls slightly inclined in direction to the garbage input open-ing 27 of the ~-ontainer 30 In raid posltion ready for operation, the strlp 25 constituting a pivotable slide is in an approximate-ly horizontal position to ~he sliding plane of the press rneans 6.
As can be seen from F~g. 3, the shaft 19 is arranged close bslow the upper edge 28 o~ the garbage inlet opening 27 in the end portion of the tipping section or in the border -qecticn between the garbage inlet open~ng and the tipping seation so that the nose-like strip 27 constituting a sensing element is activated when bulky or transversely ly~ng parts are ~ammed bet-ween the strip 27 and the upper edge 30 o~:the press means 6.
Add~tionally, also the slide-like strip 25 has the fun~t-ion of a se~sing element since said strip is also plvotad when bulky or ~amming parts come to lie between said strip and the press means~
The upper edge 30 o~ the prass means is inclined in the representsd manner in order to enable a better sliding of ob-~ects for avoiding a Jam.
If during the tipping and propelling operation a torque is exerrised on the shaft 19 through discharged obJects pushing against the strips 24 or 25, the pressure o the pressure means in the cylinder 22 i~ increa~ed which i~ monltored by a pressure feeler or the like. When sald presaure exceeds a critical ~alue, a signal is generated whlch changes the switching of the hydraul-ic cylinder 12, 13 ~o that the pres~ means i~3 moved in its re-tracted position and the operator can remove obJ~ats b~ing tilt-ed or causing a ~am from -the tipping ~eotion vr the garbage in-let opening.
When the driver is informed on a jam above the tipplng section in the garbage inlet opening by sensing means 5not shown~, he can break up said jam by rotation of shaft 19 through operating the hydraulic cylinder 22.
Furthermore, there is the possibility to press objects protruding out over the garbage inlet opening 27 by means of the claw-like strip 25 into the container 3 by a corresponding ope-ration of the hydraulic cylinder 22.
A Jam or tilting of objects above the tipping sec~ion 5 in the garbage inlet opening 4 can occur when ob;ects are ~a~med P~g. between the funnel-shaped inclined wall 32 and the opposite wall of the garbage inlet opening. If such a ~am occurs, the ob-~ects can be pressed down by pivoting the claw-like strip 25 in the tipping section 5, so that the ob~ects can be seized by the press means 6.
The shaft 19 is of course controlled such that the press means 6 cannot be moved towards the claw-like strip 25.
