Description

BACKGROUND OF THE INVENTION The invention relates to a feed hatch mechanism according to the preamble of claim 1.

The invention relates generally to hatch mechanisms and in particular to material hatch mechanisms. The invention is particularly directed to feed hatch mechanisms 10 which are intended to limit material feed from the feed opening at a time to a certain maximum volume. With respect to the feed hatch mechanisms, the invention relates in particular to solutions for supplying up to a certain maximum volume of material, wherein the feed hatch mechanism is pivotable between a first position, i.e. an outwardly open feed position, and a second position, an outwardly closed drain position.

Typically, for example, in connection with the feed openings at the material collection points for waste collection, there is often a problem of feeding too much material from the feed opening or of feeding inappropriate material, typically too large pieces of material. An attempt has been made to limit this by providing mechanisms in the feed hatch to prevent the feeding of too much material or too large pieces from the feed opening. One hatch mechanism is disclosed in WO 2004/087538. The solution comprises a hatch having fixed side walls movable with the hatch and a movable bottom wall which must be movable between two positions, an open position and a closed position. The solution further comprises two guide walls formed with guide slots guiding the movement of the bottom wall between the open position and the closed position. The solution according to the reference is difficult to modify for various application applications. Furthermore, the walls of the various parts of the mechanism are difficult to clean.

The object of the present invention is to provide a novel solution for the feed hatch mechanisms in general, and in particular for the feed hatch feed hatches for waste feeds used in connection with garbage containers or waste shafts, particularly waste vacuum systems. The object of the invention is to provide a feed hatch mechanism which avoids the disadvantages of the prior art. It is a further object of the invention to provide a feed hatch mechanism which is easily modified for various applications. It is a further object of the invention to provide a feed hatch mechanism which is easy to clean.

The feed hatch mechanism according to the invention is characterized in that the material supply space is formed by a tubular part pivotally arranged about a pivot axis arranged in the hatch, and a bottom part 10 arranged in the hatch that the tubular part is arranged to move relative to the bottom the tubular portion over the base portion such that the base portion closes the material supply space outlet in the tubular portion, the hatch in a first position and a second position in which the tubular portion has moved away from the base portion, wherein the material supply space 15 outlet is open rotating movement of the hatch of the tubular member between the first and second positions.

The feed hatch mechanism of the invention is further characterized by what is stated in claims 2-12.

The solution according to the invention has numerous significant advantages. By arranging the material supply space of the feed hatch mechanism to consist of a tubular portion and a bottom portion with respect to which the tubular portion is moved by means of a binding member, a reliable and easily modifiable feed hatch mechanism is provided. When the transmission mechanism comprises a bandage member, such as a band, wire, wire, chain or the like, a favorable solution is provided for transmitting motion and applying a pivoting force in the discharge of the feed space. The shape and volume of the feed space can easily be varied according to the requirements of Embodiment 30 by changing the tubular member of a different shape to the mechanism. The tubular member can be easily replaced, if necessary, and its material easily adapted to the requirements of the application. The feed hatch mechanism of the invention can be used in a wide variety of applications in connection with rubbish bins, various containers, feed points for pneumatic tube transport systems, waste shafts, waste transfer systems.

DETAILED DESCRIPTION OF THE INVENTION

Figures 1-5 show an embodiment of the feed hatch mechanism 1 according to the invention mounted on a support structure 5, such as a body of a reception point. A support opening 5 is formed in the support structure 5, such as the body of the receiving point, in which the feed hatch mechanism 1 is arranged. In the embodiment of the figures, the feed hatch mechanism 1 comprises a support part 3, which in the embodiment of the figure is a frame part separate from the body 5 of the receiving point and inserted into the feed opening of the feed point.

The feed mechanism further comprises a hatch member 2 which is pivotally supported on the support structure, most preferably pivotally about the axis 4. In the embodiment of the figure, the axis 4 is a horizontal axis arranged near the lower part of the feed point of the feed point 5. In the embodiment of the figure, the shaft 4 is a hinge pin 4 on which the door 2 is hinged at its lower part.

The door 2 is provided on its inner wall side with a bottom part 7 extending from the plane of the door to the side of the inlet, typically extending therethrough. The bottom part 7 is a plate-like portion transverse to the plane of the door.

The hinge 2 is provided with a pivotally supported tubular member 6 which, in the embodiment of Fig. 15, comprises a circumferential wall (6A, 6B, 6C, 6D) and a material space V open at the first end of the tubular member and the second end of the tubular member. the upper end aperture 21 is the material space V inlet. In the situation of Fig. 1, the tubular portion is arranged against the bottom portion 7 so that the opening 20 of the second end, lower end 20 of the tubular portion is against the bottom portion 7. The tubular portion and bottom portion 7 thus constitute a material space V, i.e. volume.

The tubular part 6 is hinged, preferably at its upper part, to pivot about a pivot axis 8 provided in the door 2. Between the tubular member 6 and the support structure is provided a bonding member 10, such as a band, wire, wire, chain or the like, which in the tensioned position, particularly when the hatch 2 is closed, is arranged to exert a force effect on the tubular member 6 From the situation in Figure 1 to the situation in Figure 3. The other end, i.e. the lower end, of the tube-like portion 30 moves relative to the bottom portion 7 of the hatch 2 so that the passage from the lower end of the tubular portion opens. This allows the material inside the tubular member to move away from the open end of the tubular member at the open end of the other end, i.e. the lower end, and is discharged to the receiving point.

In the first position of the door 2, in the open position, i.e. in the feeding position in the position shown in Fig. 1, the tubular part 6 is arranged at its lower end against the bottom part 7 so that material can be fed into the feed container space defined by the walls The bandage portion 10, which in the embodiment of the figure is a flexible band member, is first disposed at anchorage point 11 and at the other end at anchorage point 12 of tubular member 6. In the situation of Fig. 1, bandage member 10 does not align with tubular member 6. significant force effect. When the hatch is closed, the binding member 10 enters a tensioned state (Fig. 2), from which position it begins to exert a force on the tubular member 6. In Fig. 2, the hatch is very close to the closed position. -15 degrees, typically 5-10 degrees, preferably 6-8 degrees, whereby when the door is further closed, the binding member 10 exerts a force effect on the tubular member 6, as a result of which the tubular member 6 begins to rotate about the pivot axis 8. As the hatch extension continues, the bandage portion 10 remains tensioned and the tubular portion 6 continues to pivot about the pivot axis 8 around the position of Figure 3.

The intake port inlet port and the intake hatch mechanism 1 are so arranged in size and shape that no material can be fed from the intake port in the intake point in the normal operating position except through the hopper in the intake hatch mechanism.

The tubular member 6 may be of a desired cross-sectional shape, such as rectangular, polygonal, triangular, circular, oval. The tubular member need not be symmetrical. It may also be, for example, truncated cone shaped, funnel-shaped, etc. The tubular member is typically formed of metal or plastic. It is easy to replace and easy to clean.

In the figure, the tubular member 6 is a shaped tube profile having four straight wall portions 6A, 6B, 6C, 6D with a rounded corner portion between each adjacent straight wall portion.

Preferably, a torsion spring member 9 is provided adjacent to the pivot axis 8, which tends to pivot the tubular portion towards the rear surface of the door 2. The opening of the door 2 thus ensures that the tubular part 6 is moved to the position of Fig. 1.

Figures 4 and 5 are also perspective views showing the door open or feed position and the door closed or discharge position. In the figures, the mounting surface of the hatch 5 of the support structure is inclined. This facilitates the feeding of material into the feeding vessel. The mounting surface of the door and the extent of opening of the door 5 can be adapted to suit each application. In the embodiment of Fig. 5, a locking member 22 is provided adjacent to the gripping handle 13 of the door 2, by means of which the door can be locked in the closed position. The counter part 23 of the locking member 22 is in the frame part 3.

Figures 6 and 7 further show another embodiment of the feed hatch mechanism according to the invention. In Fig. 6 the mechanism is shown in the open position, i.e. in the feeding position, and in Fig. 7 the door is in the closed position, i.e. in the emptying position. The mechanism in this embodiment comprises damping means 15 for closing and / or opening the door. In the case of Figures 6 and 7 15, the damping means 15 also acts as a latching means 2 which, in a preferred embodiment, also holds the locking member 2 in the hinge part. . The forces acting on the feed hatch mechanism 20 of the damping means 15 and the bandage portion 10 are arranged in the closed position so that the hatch remains in the closed position and does not remain, for example, in the gap. Correspondingly, the forces of the feed hatch mechanism are arranged in the open position so that the hatch remains in the open position.

To support the base portion, the mechanism may comprise a support plate 14. There are two support plates in Figure 25 and support the base member at opposite side edges. The support plates 14 form the side walls of the base portion which support the tubular member in at least the first position, while ensuring that the tubular member engages as it moves into the first position when the door is opened.

The invention thus relates to a feed hatch mechanism for feeding material comprising a hinged pivot 2 and a material feed space operably connected to the support structure, which in the first or open position of the hatch can be filled with material and in the second or closed position. According to an embodiment of the invention, the material supply space V is formed by a tubular part 6 pivotally arranged about a pivot axis 8 arranged in the door 2, a bottom part 7, 7 and a tubular part 6 arranged in the door 2 arranged to move between the at least two positions the tubular portion over the bottom portion such that the bottom portion 7 closes the material supply space outlet opening in the tubular portion 6, the hatch 2 in a first position and a second position 5 where the tubular portion 6 has moved away from the bottom portion, with the material supply space V outlet 20 open; that the mechanism comprises a bandage member 10 which operatively engages the tubular member 6 in a pivotal movement of the door 2 between the first and second positions.

Between the tubular member 6 and the support structure is provided a bonding member 10, such as a ribbon, wire, wire, chain or the like, arranged in a tensioned position, particularly when closing hatch 2, to exert a force effect on the tubular member 6 relative to the pivot axis 8.

Typically, the bandage member 10 has at least one first position in which it does not impart movement and at least one second position in which it prevents movement of the hatch member 2 on the tubular member 6.

According to a preferred embodiment, the bandage member 10 is fixed at its first end 20 to a fixed support structure, such as a frame 3 or wall 5, and at its other end secured to the attachment point 12 of the tubular member 6.

The tubular member 6 may be formed in cross-section to meet the requirements of the application. It may be, for example, circular in cross-section, bog-shaped, triangular, polygonal, or oval. Other shapes are also available as required.

The shape of the tubular member may also vary from the inlet to the outlet. The tubular member 6 may thus be, for example, a cylindrical or conical member. 30 Other suitable forms are contemplated.

In accordance with one embodiment of the invention, the tubular member 6 is typically metal or plastic. Other materials are possible.

The feed hatch mechanism further comprises damping means 15 for damping the pivoting movement of the hatch 2. The damper can dampen movement when opening the hatch and / or when closing the hatch. The damper may be, for example, an 8 inch cylinder piston member known per se. In one embodiment of the invention, the damper acts as a locking member for the door 2. This ensures that the door remains at least in the closed position.

According to one embodiment, the bandage portion 10 is arranged at its first end in the hatch frame portion 3.

In one embodiment, the bandage member 10 is attached at one end 12 to the upper portion of the tubular member 6. What is essential for the attachment points of the dressing member is that it transmits the movement from the desired position of the hinge swing movement. On the other hand, the length of the bandage portion can be minimized, for example by arranging according to the embodiment of the patterns. By attaching the binding member to the frame, the entire feed hatch mechanism can be mounted in the opening of the installation site as a whole.

According to one embodiment of the feed hatch mechanism according to the invention, the mechanism comprises a spring means, such as a tubular part 6 of a torsion spring 9, for moving from a second position to a first position.

According to a preferred embodiment of the invention, the feed hatch mechanism 1 20 is adapted to be used, in particular, as a feed hatch mechanism for the feed point of a waste shaft or material, especially waste, in a vacuum transfer system.

It will be apparent to one skilled in the art that the invention is not limited to the embodiments set forth above, but may be varied within the scope of the appended claims. If necessary, the symbols which may appear in the specification together with other characteristics may also be used separately.
