Description

Loading device

Technical Field

The present invention relates to a loading device that transfers goods (e.g., sacks, bags, boxes, etc.) to a transport device (e.g., a truck, train, or container) using a transfer path extending between a receiving location and a discharge location.

Background

Current loading devices are used for transferring goods to a transport device, in particular a freight truck, using a transfer path extending between a receiving position and a discharge position, whereby the transfer section after the receiving position is known to have at least one driven transfer conveyor for actively transferring the goods. Contaminants and/or pollutants (especially dust, more especially cement dust when transferring cement bags) are produced when transferring goods from a receiving location to a discharge location and when handling goods on a loading device.

Disclosure of Invention

The object of the present invention is to improve the loading device in general in such a way that the above-mentioned disadvantages are eliminated.

In order to solve the above problems, the present invention provides a loading device for transferring goods to a transport device, comprising a transfer path extending between a receiving position and a loading position, wherein the transfer path comprises a plurality of goods transfer and/or processing stations, wherein the loading device further comprises at least one suction unit providing for suction of contaminants and/or pollutants from at least one of the goods transfer and/or processing stations. The present invention provides for the provision of air extraction units at one or more or all of the cargo transfer and/or handling stations. Thus, the amount of contaminants and/or pollutants, in particular dust, generated around the system can be at least reduced. The solution described herein reduces contamination of goods (bags, etc.), factories, trucks. In addition, the emission of contaminants and/or pollutants (e.g. dust) is reduced and thus an improved air quality is achieved in the factory and in the area around the factory, which includes the loading device according to the invention.

In a preferred embodiment the goods transfer and/or processing station comprises one or more of a goods receiving station, a transfer conveyor station, a goods pressing station, a goods rotating station and a position shaping station.

It has proven advantageous that the suction unit at each goods conveying and/or processing station is configured as a hood which is connected to the air suction system via a tube (e.g. a hose). The air extraction system is advantageously realized as a simple structure with one air suction system, which is connected with the hood via a tube at each station. The cost of the air extraction system can also be reduced, since only one air extraction system is provided for all hoods. With this arrangement, dust generated at each station of the loading device can be immediately evacuated by the air suction system via the tube.

Further, it has proven advantageous that the hood is located above the individual stations. By arranging the cover in this manner, the space above each station is well utilized and the cover does not interfere with the transfer and handling of the goods.

Further, it has proven advantageous that one or more hoods are provided at the position-forming station. Preferably, at least two hoods are provided at the position-forming station to ensure that the goods discharged on the transport means (e.g. a truck) remain at least substantially clean.

Further, it has proven advantageous that the air suction system is configured with a slotted duct configured as a concentrator connected to the tube of the hood and an air suction unit connected to the slotted duct. Preferably, an air suction unit is provided for all hoods. With this arrangement, the slotted duct collects dust-laden air centrally from all hoods in a simple manner. Optionally, the one or more tubes are connected directly or indirectly to the air suction unit without the need for slotted tubing.

Further, it has proven advantageous that the air suction system further comprises a filter, which is preferably connected to the slotted pipe. The air containing contaminants and/or pollutants drawn through the hood may be filtered by the filter and the filtered air may be released directly into the environment.

Further, it has proven advantageous that a fixed pipe runs through the slotted pipe for guiding at least an axial movement of the slotted pipe. The fixed pipe may perform not only the function of holding the slotted pipe but also the function of guiding the movement of the loading device.

Further, it has proven advantageous if the transfer conveyor station has one or more horizontal transfer conveyors and one or more ramp transfer conveyors. The suction unit at the station of the transfer conveyor is located near the transition where the horizontal transfer conveyor and the ramp transfer conveyor are connected. At this transition, the cargo has a bumpy, jerky and/or tilting movement, which can result in dust generation. By setting the suction unit at least at the transition, the dust generated can be sucked immediately before being diffused into the environment.

Further, it has proven advantageous that the hood at each goods transfer and/or processing station can be adjusted in its position. In one embodiment, the cover at the goods receiving station and/or the transfer conveyor station is adjustable, in particular the position of the cover can be adjusted relative to the goods receiving station and/or the transfer conveyor station. In another embodiment, at least the hood at the transfer conveyor station is adjustable.

Further, it has proven advantageous that the loading device comprises a plurality of hoods for one or more suction units, wherein at least two of the plurality of hoods have different dimensions. Thus, the cover may be sized to cover an area corresponding to a cargo receiving station and/or a transfer conveyor station where dust is expected to be generated. In another embodiment, some or all of the covers at the cargo transport and/or handling station may be of different sizes and shapes.

Further, it has proven advantageous that the loading device further comprises a collecting container, wherein the collecting container is arranged below at least one of the goods receiving station and/or the transfer conveyor station for collecting contaminants and/or pollutants. It has proven advantageous if the collecting container comprises a drawer which is located below the goods pressing station. The cargo pressing station typically uses a roller conveyor as a conveyor and a force is applied to the cargo at this station. By providing a drawer below the cargo press station, dust/dirt falling through the gap between the roller conveyors can be captured and collected, thereby reducing contamination for the environment.

Further, it has proved advantageous that the goods rotation station is provided with pins for rotating the goods for changing the orientation of the goods on the transfer conveyor station. The direction of the goods can be changed by a simple structure. When the pin is in the operating position, the goods collide with the pin, whereby the direction of the goods is changed in a simple manner. It has proved to be even more advantageous if the pin can be moved from the active position into the inactive position. When the pin is in the rest position, the goods do not collide with the pin and remain in the initial state. Alternatively, the cargo turning station may be configured as a dual belt turning device or clamp that grips and turns the product sideways, thereby changing the orientation of the cargo.

Further, it has proved advantageous if the position-forming station comprises a strip which extends at least in the goods conveying direction. It has proved to be even more advantageous if the strip is moved in a direction perpendicular to the goods conveying direction. With a simple structure and simple operation, the strip can be used in a particular way to arrange goods on the truck.

Further, it has proven advantageous that the hood, the tube and the slotted pipe are fixed to the loading device and can be moved along the loading device. In this configuration, the movement of the loading device does not cause damage to the air evacuation system, and the air evacuation function can be ensured regardless of the movement of the loading system. The gas evacuation system can be moved over large distances together with the entire system without any obstacles. Alternatively, not all of the cover, tube and slotted tube are fixed to the loading device. In one embodiment, only the shroud and tube are fixed to the loading device, while the slotted pipe is fixed to the ground. In this embodiment, only the shroud and tube may move with the loading device.

Drawings

In the following, an exemplary embodiment of the invention schematically illustrated in fig. 1 is described, so that further details, advantages and features of the invention may be further understood.

Fig. 1 shows a schematic side view of the basic structure of a loading device 10 according to the invention.

Detailed Description

As shown in fig. 1, the present invention provides a loading device 10 for transferring goods, such as cement filled bags, from a warehouse (not shown) to a transportation device, preferably a truck. Goods are supplied from a starting or storage location by the supplier 40. Only a portion of the delivery device 40 is shown in fig. 1. The loading device has a plurality of

transfer conveyors

121, 122, 123, 124 and 125 for transferring goods received at the goods receiving station 11 from the supplier device 40 to desired locations on the truck. The transfer conveyor referred to herein may comprise a belt conveyor, a roller conveyor, or any suitable means for transferring.

The

horizontal transfer conveyors

121, 122 of the loading device 10 transfer the goods in the horizontal direction (Y-axis direction in fig. 1), and the goods are then transferred by the

ramp transfer conveyors

123, 124, 125. The ramp conveyor 123 is pivotably connected to the horizontal transfer conveyor 122 so that the angle therebetween can be adjusted. The plurality of

transfer conveyors

121, 122, 123, 124 and 125 shown in fig. 1 is only one embodiment of the present invention. The number of the transfer conveyors can be adjusted according to actual needs. Furthermore, each transfer conveyor can be configured as a horizontal transfer conveyor or a ramp transfer conveyor according to actual needs.

In the embodiment shown in fig. 1, the cargo pressing station 13 and the cargo rotating station 14 are provided to the transfer conveyor 124. Alternatively, the cargo pressing station 13 and the cargo rotating station 14 may be located at other suitable positions, and their order may be changed. The position-forming

stations

15, 16 are arranged in the vicinity of a ramp conveyor 125, which generally comprises a platform and means for arranging goods on the platform in a specific manner.

The

transfer conveyors

124, 125, the goods pressing station 13, the goods rotating station 14, the

position forming stations

15, 16 may be mounted to the frame element. The frame member may move in three directions X, Y, Z. By adjusting the movement in three directions, the frame element can be positioned such that the transfer conveyor 124 is aligned with the ramp transfer conveyor 123, while the

position forming stations

15, 16 are put in place (e.g. close above or resting on the loading platform of the truck).

The goods receiving station 11 receives goods from the supply device 40 and transfers the goods to the transfer conveyor 121. An air extraction unit 21, here embodied as a first hood, is provided above the goods receiving station 11 to extract contaminants, such as dust or cement, from the goods receiving station 11. The suction unit 21 is connected via a pipe to the air suction and filter system 8, in order to remove dust or cement. The air pumping and filtering system 8 will be described hereinafter.

In the embodiment shown in fig. 1, the transfer conveyor station 12 transfers the goods received at the goods receiving station 11, the transfer conveyor station 12 comprising

horizontal transfer conveyors

121, 122 and a ramp transfer conveyor 123. The transfer conveyor may be a belt conveyor, a roller conveyor, or other suitable means of transfer. An air extraction unit 22, here embodied as a second hood, is located above the transfer conveyor station 12 to extract contaminants, such as dust or cement, from the transfer conveyor station 12. Preferably, as shown in fig. 1, the suction unit 22 is located above the transition between the horizontal transfer conveyor 122 and the ramp transfer conveyor 123. Alternatively, the suction unit 22 may be located above other portions of the

transfer conveyors

121, 122, 123. The suction unit 22 is connected via pipes to the air suction and filter system 8 for removing dust and cement.

At the end of the ramp conveyor 123, a goods rotation station 14 is provided to the ramp conveyor 124. Alternatively, the cargo turning station 14 may be located at other suitable locations in the loader 10. The cargo turning station 14 can adjust the orientation of the cargo on the transfer conveyor. In operation, goods conveyed on the conveyor are oriented in a desired direction. In order to make good use of the space of the truck, some cargo needs to be redirected so that the cargo is stacked in different directions on the passenger car. In one embodiment, the cargo rotation station 14 is implemented as a rotatable pin. When the pin is out of the transfer path of the goods, it is not operated and the pack is maintained in an initial state. When the pin is rotated to enter the transfer path, the goods hit the pin and thereby change the orientation of the bags on the transfer conveyor and, ultimately, the bags being transported on the truck. An air extraction unit 24, here embodied as a third hood, is provided above the cargo rotation station 14 to extract contaminants (e.g., dust or cement) from the cargo rotation station 14. The air extraction unit 24 is connected to the air suction and filtration system 8 via a tube.

The cargo pressing station 13 is provided downstream of the cargo rotating station 14. As the bag passes through the goods pressing station 13, pressure is applied to the bag to properly press the bag, thereby reducing the volume of the bag without causing damage to the bag. Alternatively, the goods pressing station 13 may be located at other suitable locations in the loading device 10. Preferably, the transfer conveyor at the goods pressing station 13 comprises a rigid element (e.g. a roller conveyor) which is rigid enough to withstand the applied force.

Position shaping stations

15, 16 are provided to ensure that the goods are stacked on the truck in a particular form. In one embodiment, the position forming station includes a platform for receiving goods from the transfer conveyor. The position-forming station further comprises a bar which extends at least in the goods conveying direction (Y-axis direction). When a plurality of goods are linearly aligned on the platform in the Y-axis direction, the bar moves the aligned goods in the X-axis direction to reposition the goods at a desired position on the platform. Thus, by means of the position-forming

stations

15, 16, the goods are stacked according to a predetermined form. Two

suction units

25, 26, here embodied as a fourth hood and a fifth hood, are arranged above the position-forming

stations

15, 16 to suck contaminants, such as dust or cement, from the position-forming

stations

15, 16. The

suction units

25, 26 are connected to the air suction and filtration system 8 via pipes.

The loading device 10 further has a drawer to access the falling dust/dirt. Preferably, the drawer-like object is located below the goods pressing station 13. Due to the roller conveyors used for the goods pressing stations 13 and the forces applied to the goods at the goods pressing stations 13, dust/dirt can easily fall from the gaps between the roller conveyors. By providing a drawer below the goods pressing station 13, dust/dirt can be collected centrally. Alternatively or additionally, a drawer may be provided below the cargo turning station 14, or other suitable station of the loading device 10.

In the embodiment shown in fig. 1, the air suction and filtration system 8 is implemented as a slotted pipe. The

hoods

21, 22, 23, 24, 25, 26 are connected directly or indirectly to the slotted duct 28 by pipes. An air suction unit is provided to the slotted duct so as to generate exhaust air sucked from the

hoods

21, 22, 23, 24, 25, 26. There is a fixed pipe 9 which can be fixed to the ground. The fixed pipe 9 runs through a slotted pipe 28 to guide the movement of the loading device 10. The loading device can move 12-13 meters along the Y-axis direction. For example, the loading device may be moved forward to reach various locations on the loading platform of the truck. Since the fixed pipe 9 runs through the slotted pipe 28, it is advantageous to guide the movement of the loading device while ensuring that the air suction and filtering function of the filter system 8 is not affected by the movement. Additionally, a filter element may be mounted to the slotted duct 28 to filter air drawn from the

shroud

21, 22, 23, 24, 25, 26.

In the embodiment shown in fig. 1, only one air suction unit and a further filter are provided to the slotted pipe 8 and are used jointly for all

hoods

21, 22, 23, 24, 25, 26. Alternatively, an air suction unit and an additional filter may be provided for each

hood

21, 22, 23, 24, 25, 26. In other words, a separate air extraction unit, air suction unit and additional filters comprising a hood may be provided for each station. In this embodiment, there is no need to connect the shroud to the slotted pipe 28 and the cost will increase.

In the present invention, the entire gas evacuation system, including the hood, tubes, and slotted pipes, is mounted to the loader device 10. The gas evacuation system can move with the loading device in the Y-axis direction without any obstruction. Preferably, the loading device 10 is capable of moving 12-13 meters in the Y-axis direction. Further, since the fixed pipe penetrates in the slotted pipe, the fixed pipe may not only provide a fixing function for the slotted pipe, but also a guiding function for the slotted pipe and/or the loading device.
