Description
2282118 DEVICE FOR THE TEMPORARY STOPPAGE OF CONVEYED MATERIAL The
invention relates to a device f or the temporary stoppage of conveyed material, in particular of containers for items of luggage, which is transported on a continuously moving conveyor belt installation.
A lift-off device for flat-belt box conveyor installations is known from German Patent Application 2210761. The lift-off device serves for the controlled stopping and releasing of storage containers in waiting positions which are located in front of conveyor belt installations of limited capacity. The lift-off device consists essentially of a braking roller and a lifting roller. The two rollers are located one after the other when viewed in the direction of conveyance of the belt conveyor and are arranged laterally next to the belt conveyor. The distance of the braking roller from the listing, or stopping, roller is less than the length of the storage container to be stopped. Viewed in the direction of conveyance of the belt conveyor, the stopping roller is located at the rear and the braking roller at the front.
The two rollers are connected together via a linkage, and each can roll on an inclined flat surface which ascends in the direction of conveyance relative to the conveying plane of the belt conveyor. The front inclined surface is pivotably mounted and is acted on by a spring such that the braking roller projects above the conveying plane of the belt conveyor into the conveying path of the storage containers. The inclined surface can be locked in this position by an electromagnet for stopping a storage container. A stopping operation of a storage container takes place in the following steps. The storage container is moved over the lifting roller, which is located in the basic position beneath the conveying plane of the belt conveyor, and meets the braking roller projecting into the conveying path. The kinetic energy of the storage container is used to move the braking roller, and at the same time, via the linkage, the lifting roller, up the respective associated inclined surface. The lifting roller 2 then projects above the conveying plane of the belt conveyor. Then the braking roller reaches a position on the inclined surface in which it is locked. In the raised position, the storage container rests on the braking roller and the stopping roller and on additional rollers located on the opposite side of the belt conveyor which are mounted in fixed manner. To lower the storage container on to the conveyor belt installation, the front inclined plane is unlocked, the braking roller dips into the conveying plane of the conveyor belt installation and the lifting roller is drawn by another spring into its basic, lowered, position.
Although this stopping device is distinguished by the utilisation of the kinetic energy of the storage containers for raising or stopping the storage containers, the proposed use of a braking roller and a lifting roller which are connected together by means of a linkage and are each movable across inclined running surfaces to raise the transport containers is very costly in terms of design. Furthermore, it has proved disadvantageous in that, when the electromagnet fails in the unlocked position of the pivotable inclined running surface, the storage containers may pass the lift-off device and thus run uncontrolledly into the adjoining conveyor belt installations. Furthermore, the braking roller has to project relatively far past the conveying plane of the belt conveyor in order to ensure the necessary frictional grip between the braking roller and the underside of the storage container, which is necessary for the rolling movement of the braking roller and lifting roller up the inclined surface. This position of the braking roller results in the storage container running relatively roughly on to the braking roller, and thus the latter is subject to great wear.
It is an object of the invention to provide a device for the temporary stoppage of conveyed material which is transported on a continuouslymoving conveyor belt installation which has low construction costs and at the same time permits reliable stopping and restarting of the 1 3 conveyed material.
A device for the temporary stoppage of material transported on a continuously moving conveyor belt installation, in accordance with the invention, comprises at least one lifting unit for lifting off the conveyed material from the conveyor belt installation, the lifting unit having a bar oriented with its longitudinal extent in the direction of conveyance of the conveyor belt installation and drive means for moving at least part of the bar above the support plane of the conveyed material on the conveyor belt installation.
Essentially the lifting element for the stopping device is formed from a bar which is oriented with its longitudinal extent in the direction of conveyance of the conveyor belt installation, and an associated drive means. Owing to the relatively large surface of contact with the underside of the conveyed material, the bar permits reliable and accurate stopping thereof. Adaption of the length of the bar to the length of the conveyed material increases this advantageously.
Advantageously, the bar is pivotally mounted about a spindle oriented transversely to the direction of conveyance, which is arranged at the rear of the bar, viewed in the direction of conveyance. The bar, in its rest position, is located beneath the conveying plane of the conveyor belt installation, so that there is no contact between the conveyed material and the stopping device. The bar, in its stopping position, has its rear end beneath the conveying plane of the conveyor belt installation and forms an inclined surface, starting from the conveying plane of the conveyor belt installation. This inclined surface permits gentle lifting of the conveyed material from the conveyor belt installation.
A spring element may be provided for the pivoting movement of the bar into its stopping position so that, if the drive means which moves the bar out of the stopping position into its rest position fails, the storage 4 containers will slide softly on to the bar and be stopped. The drive means is advantageously designed as a pneumatically-operable piston- cylinder unit.
In the event that the conveyed material projects sideways past the conveyor belt installation, the bar may be. arranged laterally next to the conveyor belt installation in each case. This means that no interruption in the conveyor belt installation is necessary. This allows configuration of the conveyor belt installation as a belt conveyor.
The invention will now be further described by way of example only with reference to the drawings in which:- Figure 1 is a top view of a conveyor belt installation with a device for stopping conveyed material in accordance with the invention; Figure 2 is a side view of the installation of Figure 1 showing the stopping device in the rest position; Figure 3 is similar to Figure 2 but shows the stopping device in the stopping position; Figure 4 is an end view of the installation of Figure 2; Figure 5 is an enlarged sectional view of part of Figure 4 in the region of a bar; and Figure 6 is an enlarged sectional view of part of Figure 3 in the region of the bar.
Figure 1 shows a plan view of a section of a conveyor belt installation 1 with a conveyor belt 2. The conveyor belt 2 has a width which is approximately half the width of the conveyed material transported thereon. Accordingly, the conveyed material projects sideways beyond the conveyor belt 2. The conveyed material comprises dish-shaped containers 3, each of which can be loaded with an item of luggage 4. A guide rail 5 for the containers 3 is located on the side next to the conveyor belt 2 (see Figure 4).
Bars 6 are arranged next to the conveyor belt 2, viewed in the direction of conveyance F of the conveyor belt installation 1, which bars 6 form part of a device for the temporary stoppage of the conveyed material. The bars 6 can be lifted above the conveying plane of the conveyor belt 2 to stop the containers 3, in order thereby to 1.ift off a container 3 which is to be stopped from the conveyor belt 2. Three pairs of bars 6 are provided one after the other and spaced apart in the direction of conveyance F. The length of the bars 6 corresponds in each case approximately to the length of the containers 3 being greater than half but less than the length of the containers 3.
By virtue of a control-related connection of the stopping devices to the bars 6, the stoppage of three containers 3 without dynamic pressure is possible, in order for instance to load or unload them.
Figure 2 shows a side view of Figure 1 from the region of a stopping device with the bar 6, which is preferably made of rubber and is attached to a U-shaped support 7. The bar 6 may also be provided with a friction lining. The support 7 is connected to a counter-support 9 by means of an articulation with a spindle 8 which is oriented transversely to the direction of conveyance F. The counter-support 9, which is likewise Ushaped, is arranged opposite the support 7 and connected in stationary manner to the conveyor belt installation 1. The openings of the U-shaped supports 7, 9 face one another. The spindle 8 of the articulation, viewed in the direction of conveyance F, is located in the region of the rear end of the support 7 or counter-support 9, so that the support 7 with the bar 6 is pivotable out of a rest position, i.e. the bar 6 is located beneath the conveying plane of the conveyor belt 2, and into a stopping position.
In Figure 3, the bar 6 of Figure 2 is shown in its stopping position. The stopping position of the bar 6 is distinguished in that, viewed in the direction of conveyance F, the bar 6 forms an inclined surface which 6 ascends in the direction of conveyance F, starting from the conveying plane of the conveyor belt 2. Accordingly, the rear end of the bar 6 in the stopping position is located beneath or on a level with the conveying plane of the conveyor belt 2. The pivoting movement of the support 7 with. the bar 6 takes place by means of a spring element 10 which is located between the ends of the support 7 and the counter-support 9 which are remote from the spindle S. The spring element 10 is relieved of stress in the stopping position. To lower the bar 6 into its rest position, a piston-cylinder unit 11 is located adjacent to the spring element 10 between the support 7 and the counter-support 9. Provision is made by means of circuitry to move the bar 6 into its stopping position at the moment at which the rear edge of the container 3 has just passed the spindle 8. This ensures that the entire container 3 is lifted off the conveyor belt installation 4 and can be stopped accurately.
Figure 4 shows a side view of Figure 2. It can be seen that the container 3 is transported in the middle region of its supporting surface on the conveyor belt 2. The conveyor belt 2 moves on a supporting plate 12, which is a component of the conveyor belt installation 1. The supporting plate 12 is attached laterally to a frame 13 in each case, which is supported in stationary manner for instance on the floor of a hall. Furthermore, the countersupport 9 of the lift-off device is attached to the frame 13 beneath the supporting plate 12. It can further be seen that the supporting plate 12 in the region of the bars 6 of the stopping device which project in from below is recessed correspondingly to provide a gap. Between the bar 6 and the conveyor belt 2, a guide rail 5 is attached to the supporting plate 12 on one side of the conveyor belt 2. The guide rail 5 engages in a correspondingly formed groove 14 in the base of the container 3, in order to guide the latter on the conveyor belt 2.
Figure 5 shows an enlarged section of Figure 3 in the region of the drive means 15 of the stopping device. The 0 k z 7 drive means 15 consists of a piston-cylinder unit 11 and spring element 10. The spring element 10 is located between the support 7 and the counter-support 9. Additionally, the support 7 and the counter-support 9 are guided on each other via a guide spindle 17. The guide spindle 17 is located centrally in the spring element 10 designed as a helical spring. The piston-cylinder unit 11 located adjacent to the spring element 10 is connected in each case by a connecting element 16 to the support 7 and the counter-support 9.
Figure 6 shows a section through Figure 5 along line I - I. It can be seen from this Figure that the connecting elements 16 are arranged relative to each other such that an installation space for the piston- cylinder unit 11 is defined by the connecting element 16 attached to the counter-support 9 at the top and by the connecting element 16 of the support 7 at the bottom. By actuating the piston-cylinder unit 11, the connecting elements 16 can be moved away f rom each other and the support 7 and the counter-support 9 can be moved correspondingly towards each other. Conversely, when pressure is relieved on the piston-cylinder unit 11 the support 7 is moved into its stopping position by the spring element 10.
