The present utility model will be further described with reference to the accompanying drawings and detailed description, wherein it is to be understood that, on the premise of no conflict, the following embodiments or technical features may be arbitrarily combined to form new embodiments.

It will be understood that when an element is referred to as being "fixed to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may be present. The use of "vertical," "horizontal," "left," "right," and similar expressions are for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used in the description of the utility model herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

Fig. 1 to 3 show a fall protection conveyor according to a preferred embodiment of the present utility model, which comprises a transfer conveyor 1, a swing interception plate 2, and a transport trolley 3. The transfer conveyor 1 is used for supporting a workpiece and conveying the workpiece (e.g., copper clad laminate) to the transport trolley 3. The swing interception plate 2 is located at the discharge end of the transfer conveyor 1, the swing interception plate 2 is hinged (preferably pivoted) to the frame of the transfer conveyor 1, and the unbalanced side 21 of the swing interception plate 2 and the interception side 22 of the swing interception plate 2 are oppositely arranged, and the unbalanced side 21 naturally sags in a gravity mode (i.e. uses self gravity as reset power) so that the interception side 22 is located above the conveying surface of the transfer conveyor 1 to intercept the workpiece. That is, in a natural state, the weight of the unbalanced side 21 is greater than that of the intercepting side 22, so that the unbalanced side 21 swings downward and the intercepting side 22 swings upward, so that the intercepting side 22 can intercept the workpiece (in this embodiment, the workpiece is supported by the carrier plate, and thus the intercepting side 22 is in direct contact with the carrier plate). The transport carriage 3 can jack up the weight-off side 21 to swing the blocking side 22 to move below the transport surface.

In operation, when a workpiece is transferred onto the transfer conveyor 1 and waiting for the transport trolley 3, the workpiece is intercepted by the swing interception plate 2 to prevent falling. As the transportation cart 3 approaches and lifts up the unbalanced side 21 of the swing interception plate 2, the unbalanced side 21 swings circumferentially upward, and the linkage interception side 22 swings circumferentially downward, so that the interception phenomenon of the workpiece by the interception side 22 is eliminated, and thereafter, the transfer conveyor 1 can transport the workpiece onto the transportation cart 3.

Obviously, based on the fact that the swing interception plate 2 is hinged with the frame of the transfer conveyor 1, the unbalanced side 21 of the swing interception plate can droop by utilizing self gravity, so that the interception side 22 of the linkage swing interception plate 2 swings upwards to intercept a workpiece, and the precondition of releasing the interception mode is that the trolley 3 and the transfer conveyor 1 are in butt joint, so that the phenomenon of falling down of the workpiece can be avoided. Moreover, the interception plate 2 is reset by gravity, so that the cost is low, the control mode is reliable, and the cause of the disease is easy to find during maintenance.

Preferably, a fall protection conveyor further comprises a guide rail 4, and the trolley 3 is supported and guided by the guide rail 4. The transportation trolley 3 is guided by the guide rail 4, so that the transportation trolley 3 has the same position when pushing the swing interception plate 2 every time, i.e. the direction of the transportation trolley 3 is not required to be controlled manually.

Preferably, the intermediate transfer conveyor 1 is provided with a double-sided guiding structure, the conveying surface is located between the double-sided guiding structures, the double-sided guiding structure is used for limiting the bearing plate, so, when the swing interception plate 2 intercepts the workpiece, even if the intermediate transfer conveyor 1 continuously operates, the workpiece cannot be subjected to horizontal rotation movement phenomenon due to guiding and limiting by the double-sided guiding structure, and falling to the ground in a horizontal rotation movement mode is prevented. In this way, the swing interception plate 2 can be arranged at the left side edge or the right side edge of the transfer conveyor 1 without being necessarily arranged at the middle position, i.e. the position arrangement is more arbitrary, and at this time, the transportation trolley 3 runs in place to abut against the swing interception plate 2.

Preferably, the anti-falling conveying device further comprises a material frame 5 and lifting equipment 6, wherein the material frame 5 is provided with a plurality of layers of bearing areas 51, and the bearing areas 51 are used for accommodating workpieces; the lifting device 6 is used for transferring the work pieces on the work piece carrier 5 to the transfer conveyor 1. The material rack 5 can be placed in the hot press, so that all workpieces (such as copper-clad plates) are heated, and then the workpieces are taken down one by one through the lifting device 6. Wherein the lifting device 6 may be a combination of a motor and a chain or the like.

Preferably, in order to facilitate the removal of the workpiece, the lifting device 6 is provided with a pulling manipulator for pulling the workpiece in the holding area 51 onto the lifting device 6.

Preferably, in order to facilitate the transfer of the workpiece, the executing part of the lifting device 6 is a supporting frame 61, and when the supporting frame 61 descends, the conveying surface is located in the supporting frame 61, so that the supporting frame 61 can transfer the workpiece to the conveying surface. In this way, the support frame 61 is raised and reset only after the workpiece is transferred from the transport surface to the transport carriage 3.

Preferably, the transport trolley 3 is provided with a plurality of transport layers 31, the transport layers 31 being connected to each other at intervals; the transport trolley 3 is connected with a lifting mechanism which is in driving connection with at least one of the transport layers 31. The arrangement is that the transportation trolley 3 can support a plurality of workpieces (copper-clad plates) once running.

Preferably, the unbalanced side 21 of the swing interception plate 2 is connected with the contact 7 through the screw 8 so that the contact 7 can be finely adjusted with respect to the unbalanced side 21; the contact 7 is for abutting against the transportation trolley 3. By this arrangement, the position of the contact 7 can be finely adjusted as required, so that the transfer conveyor 1 is accurately docked by the transport carriage 3.

Preferably, the part of the contact piece 7 for abutting against the transportation trolley 3 is an arc-surface structure 71, the transportation trolley 3 is pivoted with a contact wheel, and the contact wheel is matched with the arc-surface structure 71. By this arrangement, the friction between the contact and the plate can be reduced, so that the contact 7 can work more stably.

Preferably, a travel switch is provided at the discharge end of the transfer conveyor 1. That is, even if the swing intercepting plate 2 is provided, the existing travel switch can be continued, thereby realizing a dual control mode of mechanical and electric control.

It should be noted that, referring to fig. 1, it is assumed that the discharge end of the transfer conveyor 1 is provided with a travel switch, and the swing interception plate 2 is not provided, and when the load-bearing plate moves to the discharge end of the transfer conveyor 1, a warp phenomenon has occurred based on the load-bearing plate, so that the travel switch cannot be accurately triggered, thereby making it easy to drop. Or, when the carrier tray moves to half-way, the control system misdeems that the carrier tray has been moved to end due to the warping phenomenon at the tail portion, and the carrier tray falls down obliquely along with the rising of the bearing frame 61, so that the production safety accident is easily caused based on huge workpieces.

The above embodiments are only preferred embodiments of the present utility model, and the scope of the present utility model is not limited thereto, but any insubstantial changes and substitutions made by those skilled in the art on the basis of the present utility model are intended to be within the scope of the present utility model as claimed.
