Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a textile machine in which a large number of winding devices are arranged in series in the longitudinal direction of the machine base, and the bobbins doffed by a suitable doffing device are inspected and subjected to a packing process, etc. The present invention relates to a transport method and a transport device for transporting empty bobbins to a process or to a specific position of a textile machine.

In the textile manufacturing process, there are many textile machines such as spinning machines,
Twisting machine, stretching and twisting machine (The stretching and twisting machine will be described below.

) are installed in parallel, and the work of doffing the wound bobbin, transporting it to the inspection and packaging process, and supplying empty bobbins to the spindle of each textile machine, such as a twisting machine, has traditionally been done manually. .

In recent years, automatic doffing devices have been developed that automatically perform this work in order to streamline the process.

The bobbins doffed from the twisting machine by this automatic doffing device are inserted into the pegs on the pallet in front of the machine stand, and the pallet with the bobbins placed upright is sent to the inspection and packaging process. A transportation method is used.

The pallet can be transported by storing the pallet in a pallet storage cart at the end of the twisting machine machine and transporting it to the inspection/packing process, or by connecting the stretching machine and the inspection/packing process with a conveyor, etc. Previously, the pallet was transported to the next process.

However, in the former transportation method, a pallet moving device for loading the pallets arranged in front of the stretching machine machine onto a pallet storage cart must be placed at the machine base of the stretching machine, and a traveling function is required. Since a large number of large pallet storage carts are required, each having a moving device for moving and storing the loaded pallets, the equipment cost is extremely high.

In addition, in the latter conveyance method, the mechanism of the branching and merging parts such as conveyors becomes complicated, the equipment cost becomes very high, and the conveyors etc. are installed on the floor etc., so there is no need for people to pass by or other work vehicles. It has the disadvantage that it obstructs the operation of
Furthermore, it requires a large new space in terms of equipment layout, making it particularly difficult to apply to existing equipment.

Further, as a specific example of the former, there is Japanese Patent Publication No. 49-12859, in which a moving rail is provided at the front of the twisting machine, a peg bobbin is accommodated on the moving rail, and the group of moving rails is moved in the longitudinal direction. A method has been proposed in which the materials are accommodated by moving them in parallel on a transport vehicle.

Since this method uses moving rails, it requires male and female connectors at the ends of the moving rails, making the structure complicated, and since the moving rails are made of flat steel sections, there is a risk of collisions between the moving rails. If you do this, it is likely to get dented and damaged.

In addition, since it is necessary to install a frame group to accommodate the moving rails in the transport cart, the structure of the naen becomes complicated, and the transport cart also needs a function to accommodate the moving rails and a transport function to transfer the moving rails to the next process. Therefore, the structure becomes complicated.

Furthermore, since there is a limit to the number of movable rail groups that can be accommodated, it is necessary to install a large number of transport carts that have a accommodating function and a conveying function, resulting in a disadvantage that the equipment cost is high.

In view of these drawbacks and circumstances, the present inventors have developed a mechanism for a pallet transfer device in front of a stretching machine table, which has a simple mechanism, does not require a large number of pallet storage carts, does not require a complicated conveyor, and is equipped with It is inexpensive, can be applied to the existing spacing of the twisting machine, does not interfere with the traffic of people or the operation of work carts, etc., and is easy to inspect and carry out.
The present invention was achieved as a result of intensive research into a method and device for transporting thread-wound bobbins or empty bobbins that can be easily applied in the packaging process.

That is, the first aspect of the present invention is to provide a pallet conveyor along the longitudinal direction of a textile machine, place a plurality of pallets having pegs in series on the pallet conveyor, and place bobbins on the pallets. , the pallets are moved in the longitudinal direction and guided sequentially onto the pallet storage cart, and the pallets are sequentially moved in parallel in a direction perpendicular to the longitudinal direction of the textile machine to be rearranged in a parallel state, and then all the pallets on the pallet storage cart are At the same time, a plurality of pallets with empty bobbins placed thereon are loaded in parallel onto the pallet transport trolley and transferred to the adjacent pallet transport trolley. This bobbin transport method is characterized by transporting the bobbin to a position and placing a plurality of pallets in series on a pallet conveyor by performing an operation opposite to the transport of the bobbin.

The second invention also provides a pallet conveyor provided along the longitudinal direction of a textile machine for conveying pallets having pegs for placing bobbins, and a pallet conveyed by the pallet conveyor or pallet conveyance. A means for moving the pallet in the longitudinal direction in order to receive the pallet transferred from the trolley or send it to a pallet conveyor or a pallet transport trolley, a means for moving the pallet in parallel in a direction perpendicular to the longitudinal direction, and a pallet storage truck having means for traveling in a direction perpendicular to the longitudinal direction; a means for traveling parallel to the pallet storage truck and stopping adjacent to the pallet storage truck; This is a bobbin transporting device characterized by comprising a pallet transporting truck having a pallet transfer means.

According to the present invention, since a conveyor is used to transfer the pallets in the longitudinal direction of the textile machine, the mechanism is simple, the equipment cost is low, and there are fewer breakdowns.In addition, various functions such as sorting means, transfer means, etc. It is easy to install just one pallet receiving trolley, and the equipment cost is low.The pallet transporting trolley that receives the bobbin from the pallet receiving trolley can be immediately moved to the inspection and packaging process, reducing the need for pedestrian traffic and other work vehicles. It does not become an obstacle to the operation of the train.

Further, the bobbin conveying device of the present invention includes a pallet conveyor provided along the longitudinal direction of the textile machine, a pallet storage cart,
Since it is constructed from a pallet transport vehicle, it does not require a large facility area and can be installed at the spacing of existing stretching and twisting machines.

In addition, since the pallet on which the bobbins are placed is transported as is, the bobbins do not come into contact with each other or fall over and get damaged, so there are no quality problems caused by the transportation of the bobbins.
