JPS61106330A - Disposing method of empty pallet in actual pallet feed line - Google Patents

Abstract

PURPOSE:To dispose empty pallet to the outside of line automatically or through remote control by combining the line and the carrying machine. CONSTITUTION:Upon empty of actual pallet, actual pallet feed line 3 will rotate reversely to carry the pallet into a cage 1 of waiting carry machine 4b and stop. The cage 1 mounting the empty pallet 7 will lift to the upper limit and stop then travel unit 4d of carry machine 4b will function to carry the cage 1 to the destination. Thereafter, an elevating unit 4c will function to lower the cage 1 to the lower limit and stop. At this time point, the empty pallet 7 is held by the upper face of line and separated completely from the holding section 1a of cage 1. Consequently, the switching line 5 will rotate forward to carry the empty pallet 7 to the outside of cage 1 and advance to the empty pallet line 6.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for automatically or remotely controlling empty pallets that are no longer needed after the conveyed objects have been taken out of a real pallet supply line.

Conventionally, real pallets transported by forklifts are transported by a real pallet supply line on the floor of the building that is connected to the main line, and empty pallets that are no longer needed after the objects to be transported are removed using an overhead electric trolley-type hoist. They used to lift it up and pay it out, but slinging has the drawback of causing accidents and line stoppages.

In view of the above-mentioned drawbacks of the conventional method, an object of the present invention is to automatically or remotely control empty pallets that are no longer needed in the actual pallet supply line to be delivered to the outside of the line.

By combining a line and a conveyor, the present invention makes it possible to automatically or remotely control empty pallets to be delivered out of the line.

Hereinafter, one embodiment of the method according to the present invention will be described in detail.

FIG. 1 is a schematic perspective view showing an empty pallet held in a cage according to the method of the invention.

The cage 1 (not shown) connected to the lifting device of the conveyor has a cylindrical shape slightly larger than the pallet 7, and has holding parts 1a facing inward at both ends of the bottom that can withstand the pallet load. It is equipped. FIG. 2 is a schematic plan view of the line, and FIG. 3 is a schematic side view of the line. That is, the actual pallet pool line 2 is on both sides of the actual pallet supply line 3, and the end of the line and the starting end of the actual pallet supply line 3 are partially double tracked, and the actual pallet supply line 3 and 90. Empty pallet dispensing lines 4 are arranged which intersect with each other in the vertical direction. Immediately below the end of the line, an empty pallet transfer switching line 5 and an empty pallet pool line 6 are arranged, which intersect at 90 degrees.

The real pallet boule line 2 is a driven roller conveyor, and is provided with an adjustment stopper 2a for feeding one real pallet 8. The actual pallet supply line 3 is a drive material xetabilla conveyor that can freely rotate in forward and reverse directions. The empty pallet discharging line 4 has a pair of rails 4a and a conveyor 4b that runs on the rails, which is equipped with a lifting device! f4c and lifting device 4c
A cage 1 is provided which is connected to the cage 1. Although the empty pallet delivery lines 4 are arranged to intersect in a 90 degree direction, the arrangement is not limited thereto. The elevating and lowering functions and traveling functions of the transport tl14b can be achieved by using a conventional mechanism, so a description thereof will be omitted.

FIG. 4 is an explanatory diagram of a cycle incorporating the method according to the present invention. In the first step, when the stopper 2a of the actual pallet pool line 2 is opened and the line is activated, the actual pallet 8 is transferred to the actual pallet supply line 3, and at that point, the stopper 2a of the actual pallet pool line 2 is opened and the line is activated.
a closes again. Detector 3 of actual pallet feeder 3
The actual pallet supply line 3 is forwardly rotated by a, and the line is stopped by the actuation of the detector 3b, which indicates the fixed position of the tip of the line. In the second step, the objects to be transported on the actual pallets are transferred to the main line (not shown). When the work progresses, the lift @ 4c of the transporter 4b waiting overhead is operated, and the holding part 1a of the cage 1 is moved to the main line (not shown). It descends to the lower limit lower than the pallet supply line. On the other hand, the real pallet pool line 2 rotates the new real pallet 8 forward and stops it when it reaches the stopper 2a. In the third step, when the actual pallet becomes an empty pallet, the actual pallet supply line 3 rotates in the reverse direction, and the actual pallet is conveyed to the cage 1 of the waiting conveyor 114b, and then stopped. In the fourth step, the cage 1 carrying the empty pallet 7 rises to its upper limit and stops. Subsequently, the traveling device 4d of the conveyor 4b operates to convey it to the destination. In the fifth step, the lifting device 4G operates, and the cage 1 descends to the lowering point and stops. At this point, the empty pallet 7 is held on the upper surface of the line and is completely separated from the holding part 1a of the cage 1. In the sixth step, the conveyance switching line 5 rotates forward, and the empty pallet 7 is conveyed out of the cage 1 and further advanced to the empty pallet pool line 6. The empty pallet pool line 6 is rotated forward and transported. In the seventh stroke, the lifting device 4C of the carrier 4b operates, and the cage 1 rises to its upper limit and then stops. Continuing with the transport device!
The traveling device 4d of 4b operates and the actual pallet supply line 3
The vehicle travels to a fixed position above the vehicle's head and stops.

As described above, the present invention is a method for discharging empty pallets that can save manpower by automatic or remote control, prevent disasters, have high work efficiency, and can be reliably carried out.
