Abstract

PURPOSE:To make possible the positioning of a push-pull mechanism at the fully pulled position in a device where a cargo is transferred between a storing shelf and a working equipment by holding a part to be clamped, which is designed to remain in an elevator side, with a corresponding clamp. CONSTITUTION:A cargo delivery device 5 carries an elevator 12 which can move up and down along a travelling frame 11, and a push-pull mechanism 14 which comes in a form of a folk and can be pulled out and pushed in laterally as required through the medium of a table frame 13 of the elevator 12. A pair of parts to be clamped 42 and 43 is secured directed downward under a connecting plate 25 of the push-pull mechanism 14, and it should be spaced with a specified pitch of P along the push-pull direction in the device. Also a clamping device 46 is installed on the elevator 12, where a pair of clamps 44 and 45 is arranged along the push-pull direction so as to hold the above mentioned parts to be clamped 42 and 43. When the push-pull mechanism 14 is pulled out laterally, its positioning and fixing are designed to be reliably accomplished by clamping the part to be clamped 42 with the corresponding clamp 45 properly.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to cargo delivery equipment used, for example, when a cargo delivery device transfers workpieces between a shelf and a processing device. .

Structure of conventional example and its problems In the above type of cargo delivery equipment, the workpiece is held on a jig and delivered by a cargo delivery device via a pallet. The cargo delivery device is movable along the shelf and has a loading/unloading mechanism (fork) that can move in and out of the lifting platform laterally. Therefore, by the combined movement of the overall movement, the raising and lowering of the lifting platform, and the lateral movement of the loading/unloading mechanism, pallets (workpieces, etc.) The delivery will take place. By the way, while the pallet is being moved while being supported by the loading/unloading mechanism, the loading/unloading mechanism may shake due to vibrations and the orientation (posture) of the pallet may be disturbed, or the protruding rods for passing the pallet on the tray of the loading/unloading mechanism may not be aligned. When this happened, the pallet was not handed over correctly, and
Accurate machining work cannot be carried out, especially in the recently adopted format where a cone receiver is installed in the machining equipment or cargo handling equipment and positioning is performed at the same time as the pallet is delivered, the position of the pallet is disturbed. Sometimes, the cone receivers cannot be used for positioning, and the pallet ends up climbing onto the cone receivers and tilting.

OBJECTS OF THE INVENTION It is an object of the present invention to provide cargo delivery equipment that can prevent rattling of the rice plowing mechanism while the vehicle is running, and that can also position the protruding mouse of the rice plowing mechanism.

Structure of the Invention In order to achieve the above-mentioned object, the cargo delivery equipment of the present invention is provided with: - A cargo delivery device that can freely travel on a light road, and a cargo receiving section is provided at some part of the fixed route, and the cargo delivery device has the following features: The elevating platform is provided with an in/out mechanism that can move in and out in the lateral direction, the in/out mechanism has a pair of clamped parts in the in/out direction, and a clamping tool that can freely clamp and remove the clamped parts is moved in and out of the elevating platform. A pair of clamp devices are provided in the direction.

According to this configuration, after the loading/unloading mechanism is protruded in the lateral direction, the single clamped portion remaining on the lifting platform side is clamped with a corresponding clamping tool, whereby positioning with the protruding book can be performed. After leaving the
By clamping both branch clamp portions with corresponding clamping tools, the loading/unloading mechanism can be positioned and fixed during travel.

52A) (52B) moves upward and closes to clamp the ring to the corresponding clamped portion. In other words, the first stage movable body (C) is clamped and fixed to the clamping tool @ 4 corresponding to the target of the two-wave clamp part, and thus the loading/unloading mechanism (14 is the lifting platform (6)). ) is positioned in the clamped state.Furthermore, when the ejector mechanism O is moved to one side for transfer, the receiver is placed in the other clamped part as shown in Fig. 10. ingredients)
This means that they are clamped facing each other, so that they are positioned and fixed when protruding and retracting. Note that the other protruding movement causes one clamped portion to be clamped by the other clamping tool θ.

Effects of the Invention According to the cargo delivery equipment of the present invention depicted above, after the loading/unloading mechanism is protruded in the lateral direction, one portion to be clamped remaining on the lifting platform is clamped with the corresponding clamp tool (thus, , positioning can be performed at the extension limit, and pallets (loads) can be received and transferred correctly at all times.Furthermore, after retracting into the lifting platform, the double-wave clamp parts can be moved with the corresponding clamping tools. By clamping, the loading/unloading mechanism can be positioned and fixed while traveling, and the posture of the pallet (load) can be prevented from being disturbed due to the loading/unloading mechanism shaking during traveling.

In particular, the present invention can be advantageously employed in a type of delivery operation in which pallets are positioned using cone receivers, such as in recent processing equipment.
