DEVICE TO EMPTY THE DISPENSER

The invention relates to a device for emptying a container, which device comprises a 5-frame structure, a frame for moving a container supported on the frame structure, and actuators for moving the frame and thus for emptying the container by tilting the container.

10

Devices for emptying a container, such as a waste container or a waste cart, have been disclosed. For example, garbage trucks have fixed hydraulic troughs that can be used to empty the waste bin into the load compartment of the garbage truck. Mobile devices 15 have also been developed for emptying a waste bin to, for example, a waste bin.

Known devices have adapted the features of fixed devices. Thus, they have become heavy and thus difficult to move. In addition, known actuators are based on hyd-20 raulics, which further increases the unit's own weight and increases manufacturing costs. Partially known devices, the tipping geometry requires a lot of power, which requires the use of hydraulics. At the same time, the emptying of the waste container is weak and sufficient tipping distance requires separate guide rails. This increases the dirtiness of the device and requires separate ones

o a new device with a significant tipping distance without additional attachments. Features of the present invention will be apparent from the appended claims. The invention combines various functions and utilizes new and surprising 2 structural solutions. This makes the device lightweight, which facilitates its mobility. Despite this, the robustness of the device is well established, which allows for the loading of heavily loaded containers. The new structure also requires 5 less power, allowing for simpler institutions.

The invention will now be described in detail with reference to the accompanying drawings, in which:

Generally speaking, the device is intended for emptying the container. The apparatus comprises a frame structure 10 and a movably supported frame 11 for the vessel 12. Further, the device includes actuators 13 for moving the frame 11 and thus for emptying the container 12 by tilting the container. The actuator allows even one person to empty the container without having to lift or tilt it manually. This allows the container to be emptied safely.

According to the invention, the frame 11 is arranged as a carriage 14 and the frame 10 structure 10 is arranged as a guide 15 so that the carriage 14 is arranged to travel from the bottom to the bottom of the frame structure 10 and vice versa. In other words, two different functions are provided for the frame structure. First, it provides lifting of the container, whereby the container can be emptied, for example, on the waste-bin of the equipment-15. Secondly, the frame structure is utilized as a guide for the carriage, which simplifies the structure of the device. Thanks to the sled, the emptying geometry of the device is also new and surprising. 1 2 3 4 5 6

Novel emptying geometry can be achieved in different ways.

In the embodiment shown, the guide 15 first comprises a straight portion 3 16 and then a curved portion 17 arranged above the straight portion 4 16. Here, the straight portion is substantially vertical, whereupon the vessel begins to rise straight up. With only 6 curved sections, the carriage begins to turn and the container is empty.

? More specifically, the curved portion 17 comprises a curve 18 with an angle α of 120 to 190, more preferably 150 to 180 degrees.

g 30 This allows even the container to be turned upside down, which guarantees complete g drainage. Rarely does the angle need to be fully utilized, since tilting beyond the horizontal is often sufficient to empty the cd o. Preferably, the curve 18 has a circular arc.

(M

In this case, the tipping of the container is smooth without any jerking. Further, the curved portion preferably begins only above the edge of the edge of the refuse blade (Figure 3). In this case, the curved portion is provided 4 well above the waste bin inside its edge. Thus, the entire contents of the waste bin will surely fall on the waste bin and not just on the outside of the unit. At the same time, separate control structures are unnecessary. Generally speaking, the curve 18 is dimensioned such that the center of gravity of the carriage 14 changes from 50 mm to 500 mm, more preferably from 100 mm to 300 mm, in the longitudinal direction of the frame structure (Figure 5). In this case, the contents of the container will surely drip onto the platform, even though the device itself is a little further away from the side.

10 The sled and its curved trajectory require a flexible transmission. Here, the actuators 13 include an endless loop transmission chain 19 attached to the carriage 14. By rotating the transmission chain, the carriage moves along the guide. The Path of the Power transmission chain can be made flexible and thus the next 15 carriageway paths. In addition, the transmission chain can be supported by slides or, if necessary, using sprockets. Thanks to the new emptying geometry, the transmission chain is lightly loaded, since first the container simply rises and only after lifting begins to turn with a curved portion 20, whereby part of the mass of the carriage and the container rests on the frame structure. At the upper dead center point of the curved portion, the transmission chain is almost unloaded.

Figure 2 is a rear view of the device according to the invention. The frame structure is thus arranged as a guide. Here the guide 15

In the embodiment shown, the co in tray 14 consists of two plate portions 23 which are disposed in a roller 22 disposed. There are three rolls here, 35 of which are two on the side of the pan. In this case, the mass of the container is evenly distributed on the guide and the carriage is easily rotated in a curved portion.

Rolling members may also be formed by combining single-groove rollers or discs of different diameters between which the plate body can be accommodated.

5 There are other advantages to an open, conductive frame structure. According to the invention, the transmission chain 19 is arranged substantially completely inside the frame structure 10, i.e. between the plate bodies. Indeed, this is almost fully realized in Figure 2, where the transmission chain 19 is depicted by a dotted line. For almost the entire 10 guides, the transmission chain is between the plate pieces. The frame structure also includes a vertical bar 24 having a single gear 25 at the top and an electric motor 26 mounted adjacent thereto. The electric motor is used to rotate the transmission chain back and forth and thereby move the carriage. Open points and open arms formed by the force-15 transmission chain are insulated with protective structures (not shown). This avoids injury to the operator and dirt in the transmission chain. The electric motor can also be placed on the bottom of the unit (Figure 5). In addition, by increasing the size of the guide and using gears, the entire transmission-chain can be positioned between the plate members. In other words, the transmission chain would run up and down the one side of the guide.

The vertical beam 24 has a more important function than merely supporting the electric motor. Namely, the frame structure 10 includes support members 27 for attachment to pallet 28 whose support members

The position of the 27 with respect to the frame structure 10 is arranged in a height-dependent manner. adjustable and lockable at the front. In Fig. 1, the support members 27 are located at the bottom of the vertical beam 24, but can be raised x 30 up to the electric motor 26. Here, too, the vertical beam 24 is arranged as a guide to the support members 27. Here, the support members include a transversal LO beam 29 with L-shaped support arms 30 fitted at their ends.

Two supports 31 are provided on the support arms 30 to which the edge of the waste bin is fitted. The distance of the device from the edge can be selected 35 by arranging the device between two supports or one support and the support arm. The struts can also be movable so that their 6 positions and spacing can be changed. The locking members here have a wing bolt 32 for locking. The locking can also be done in other ways. The support members can be moved by hand, but here a winch 33 is provided (Figures 2 and 6). 5 The device can be used even if its wheels are, for some reason, moved a little farther from the platform, as the support members are, however, supported on the side. In addition, the vertical beam 24 is connected to the plate members 20 of the guide 15 by two spaced apart steel bars 47. In this way, the frame structure 10 is formed into a rigid assembly and the transmission chain 19 is unobstructed.

The supporting members can stabilize the entire device when the edge of the waste bin is utilized. At the same time, the support point can be up to -15 man up, which reduces the strain on the frame structure. At the same time, the device is suitable for use with pallets of different heights. The most common changing platforms have heights of 0.5, 1.0 and 2.0 meters. In the applications shown, the height of the side is 2.0 meters.

Fig. 2 shows a lockable lifting stop 34 fitted to the carriage 14, comprising a lifting strip 35 and a locking strip 36. The lifting strip is dimensioned and shaped to accommodate the lifting collars of various containers. The locking strip allows the container to remain attached to the tray despite the tipping. Figure 2 shows 25 locking strips 36 in two positions. To the right, the locking strip is in the c \ i T ~ open position so that the lifting strip can be set

7 tipping and thus prevent overloading and thus breakage of the waste container lifting collar. On the other hand, properly dimensioning and shaping the guardrail prevents the user or other persons from getting too close to the device. In other words, the carriage 14 includes a safety rail 39 for both locking the container 12 to the carriage 14 and preventing the user of the device from being too close to the device. This will further improve occupational safety.

10 With the exception of Fig. 5, the power source is powered by a direct current electric motor 26 provided with a battery 40, which is controlled here by a controller 41 with push buttons. On the other hand, the power may be provided by a handwheel chain drive. Preferably, an AC motor with a reverser is used, which is connected to the mains by cable. This provides sufficient power to lift even large loads while keeping the weight of the device advantageously low. The lightweight device can be easily moved by hand. The transmission chain is also nearly stretchable and can also shake the vessel. Figure 5 illustrates another embodiment of the device in which the electric motor 26 to be connected to the mains is located at the bottom of the device. At the same time, the focus of the device becomes lower. A suitable speed is obtained by using a gear wheel of suitable size 42 and a gearbox 25 43 with gears. Preferably, a worm gear which is self-holding is used.

up, whereby a significant portion of the load is applied to the sides of the pallet 35. In this case, the elasticity of the rubber tires does not prevent lifting. At the same time, the support allows the side to be tilted or otherwise 8 inclined. In addition, one or more wheels may be provided with a locking device to prevent unintentional movement of the device. The wheels may also be arranged such that the device itself moves on the wheels with an obstacle, but when loaded, the wheels will retract 5 allowing the frame structure to rest on the substrate. As a result, the device is supported even more strongly.

The curved frame structure of the device according to the invention extends inside the pallet, whereby the inside of the receptacle is sure to fall onto the changing platform. At the same time, the position of the receptacle will change with respect to the changing platform, which will certainly drain the receptacle onto the pallet. In addition, the vessel tilts in a controlled manner without any sudden change in focus. In other words, the tilt point of the device changes, making separate control structures unnecessary. At the same time, waste is prevented from leaking onto the device 15.

In addition to builders and renovators, the appliance can be used in laundries, hospitals, and other public entities. Naturally, the device can be rented with the transfer platform 20 as part of a larger service. Waste bins can be emptied more easily and safely. At the same time, the demountable platform is improved, which reduces the number of demountable demountables.

35 When the container 12 is locked in the tray 14, lifting can be started using the guide 41. The receptacle 12 first rises and then turns 9 gradually (Fig. 5). When the container is empty, lower it and remove it from the tray. When this point on the replacement platform is completed, the support members will be unlocked and the device moved slightly forward along the side. Following the locking of the support members, the following containers may be emptied. Doing so will result in the quickest and most complete replacement of the platform.
