- the operating cycle occurs according to an automatic sequence and entails the following operations:
- the support 1 is not moved at all; as mentioned, said support can be rotated, under the control of the operator who is present on board the truck, only to adjust the tilt of the plane in which the arms 14 and 15 lie, in order to optimize the grip on the bin when the inclinations of the truck and of the bin resting surface are different; when it is possible to renounce this possibility of adjustment, the support 1 can be blocked with respect to the tailgate 5 of the truck.
Abstract
Description
- The present invention relates to an improved device for handling a curbside waste bin.
- It is known that devices are in widespread use which, applied to waste collection trucks, allow the automatic handling of roadside bins to empty them into the body with which said trucks are provided.
- The same Applicants disclosed in Italian patent application MN 93 A 000014 a device that has proved to be highly effective, but continuing studies have led to the improvements for which the present patent application seeks protection; said improvements have the principal aim of providing a device that has minimal bulk and can adapt to different operating conditions.
- This aim is achieved by an improved device for handling a waste bin, according to the invention, which is suitable to be coupled to a collection truck and comprises a support for a cross-member that can move axially transversely to the truck, said support being associated with the tailgate of said truck below the waste insertion opening, said device furthermore comprising means for gripping and lifting the bin which are rotatably supported at one end of said cross-member, characterized in that said grip and lifting means are suitable to produce a first lifting of the bin that moves it into a position in which it is not in contact with its normal resting surface and, after a rotation about the end of the cross-member that transfers the bin to a position that faces the tailgate of the truck, a second lifting action that overturns said bin inside the body of the truck.
- Further characteristics and advantages will become apparent from the following detailed description of a preferred but not exclusive embodiment of the device according to the present invention, illustrated only by way of non-limitative example in the accompanying drawings, wherein:
- figure 1 is a perspective view of the device according to the present invention;
- figure 2 is a view of a detail of the shaft.
- With reference to the above figures, the reference numeral 1 designates the support of the cross-member 2 which can move axially transversely to the truck by virtue of the action of the
actuation cylinder 3, which is pivoted at 4a, 4b to thetailgate 5 of a waste collection truck about an axis which is parallel to said cross-member below the waste insertion opening. - The coupling between the support 1 and the
tailgate 5 is provided so as to produce minimal protrusion of said support, and there is an actuation cylinder 6 meant to produce small rotations for adjusting the inclination of the plane that contains the bin grip arms which will be described hereinafter; these adjustment rotations are useful if the truck is parked on an upward or downward slope close to a bin to be gripped which is placed on a horizontal surface. - The sleeve 2a is provided at one end of the cross-member 2, and the bracket 7 is pivoted thereto by means of appendices 7a and 7b; said bracket can thus rotate by virtue of the action of the
actuation cylinder 8 and supports the bin grip and lifting means which are now described in detail. - Said means thus comprise the shaft, generally designated by the
reference numeral 9, which has two end pivots 9a and 9b and a median portion 9c, is inserted in thesupports 10a and 10b which are fixed onto the bracket 7, and is provided with the two pairs of lugs designated by the reference numerals 11 a and 11 b. - Said pairs of lugs support one end of
small actuation cylinders 12a and 12b which are connected, at the end of the stem, to themember 13 which is pivoted, by means of the protrusions 13a and 13b rigidly coupled thereto, on saidshaft 9 and supports, at its ends, thebin grip arms actuation cylinders 16 and 17, and are provided with telescopic stems as described in Italian patent application MN 93 A 000014. - In other words, the coupling between the
shaft 9 and themember 13 which is pivoted thereto is provided by thesmall actuation cylinders 12a and 12b. - Furthermore, the reference numerals 18a and 18b designate two actuation cylinders which are larger than the
cylinders 12a and 12b, are supported, at one end, by the tabs 7a and 7b of the bracket 7, and are connected, at the end of the stem, respectively to thecranks 19a and 19b which are rigidly coupled to the pivots 9a and 9b respectively of theshaft 9. - The operation of the invention is now described starting from the position shown in the figure, in which the cross-member 2 is extracted from the support 1 by the appropriate amount so as to make the
arms arms - The operating cycle occurs according to an automatic sequence and entails the following operations:
- -- the
arms - -- while the actuation cylinders 18a and 18b are blocked, and thus while the
shaft 9 is fixed, theactuation cylinders 12a and 12b are activated, causing a small rotation of themember 13 about theshaft 9 and consequently lifting thearms - -- the stems of the
arms tailgate 5 of the truck; - -- while the
actuation cylinders 12a and 12b are blocked, and therefore while themember 13 is rigidly coupled to theshaft 9, the actuation cylinders 18a and 18b are actuated, causing a significant rotation of saidshaft 9 and accordingly of thearms - Of course, the same steps described above are performed to return the bin to the initial position.
- The above description clearly shows the advantages of the invention and in particular that it has been possible to achieve small bulk by making the means supported by the bracket that is hinged to one end of the cross-member perform all the functions for gripping and lifting the bin in two steps from its normal resting level to the level for emptying it into the truck.
- In terms of this bulk reduction, the choice to use two pairs of actuation cylinders, each of which has the purpose of performing one of the two bin lifting steps, is particularly important.
- It has been observed that during the described automatic operating cycle the support 1 is not moved at all; as mentioned, said support can be rotated, under the control of the operator who is present on board the truck, only to adjust the tilt of the plane in which the
arms tailgate 5 of the truck. - The described invention is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept: thus, for example, a single pair of actuation cylinders provided with an intermediate stroke limiter may perform both bin lifting steps.
- Where technical features mentioned in any claim are followed by reference signs, those reference signs have been included for the sole purpose of increasing the intelligibility of the claims and accordingly such reference signs do not have any limiting effect on the interpretation of each element identified by way of example by such reference signs.
