DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cake pick-up / removing machine used when a cake conveyed from a twisting machine by a trolley conveyor is mounted on a creel of a tire cord loom or the like.
The present invention relates to a mounting device.

[0002]

2. Description of the Related Art For example, a fiber thread used for a tire cord is formed by twisting a strand of a synthetic fiber or the like with a twisting machine, winding it around a bobbin, and winding it (hereinafter referred to as cake).
Is formed. Conventionally, the cake after the twisting machine has been manually mounted on a creel stand equipped with casters and transported to a place where a tire cord loom is installed.

[0003]

The cake for a tire cord is required to have an increased amount of winding yarn, and accordingly, the weight of the cake is 10 to 15 kg.
In the conventional method in which the cake after the twisting machine is manually attached to the creel stand, the labor burden on the operator becomes excessive, and the creel stand with casters is moved from the position of the twisting machine to a tire cord manufacturing apparatus. A great deal of labor is also required to transport them to a position, and these labor savings are demanded.

[0004] As means for conveying these cakes, for example, a trolley conveyor may be employed. An apparatus for mounting the cake after the twisting machine onto the trolley conveyor and an apparatus for removing the cake from the trolley conveyor and mounting the cake on a creel stand. Need to be developed.

The present invention proposes an apparatus for taking out a cake carried on a trolley conveyor from the trolley conveyor and mounting the cake on a creel stand.
It is an object of the present invention to provide a cake take-out / mounting device which does not contaminate the wound layer of the cake, prevents the collapse of the cake, and has a small and simple structure and is easy to handle.

[0006]

To achieve the above object, the present invention provides a trolley conveyor which inserts the tip of a support rod into a center hole of a bobbin to support and transport cake in a direction parallel to the transport direction. The trolley can be moved up and down in the lower part of the conveyor path, and is driven at the same speed at the beginning in the same direction as the trolley conveyor, gradually increased in speed, and driven at a speed higher than the trolley conveyor's transport speed. The cake conveyed by the conveyor is pulled out from the support rod and taken out, and the take-out conveyor that descends and the take-out conveyor that descends and is located at the end side of the take-out conveyor and chucks the cake taken out onto the take-out conveyor with chuck claws. A transfer mechanism that chucks with the pallet and transfers it upright on the pallet of the pallet conveyor, and a pallet that transfers the cake transferred by the transfer mechanism. Is placed upright on a pallet conveyor for conveying the creel mounting position, is installed in the middle of the pallet conveyor, positioning the creel stand,
Inserting a gripping member into the bobbin center hole of the cake conveyed by the pallet conveyor, grasping the cake and mounting it on the holder of the creel stand, and detecting and taking out the cake conveyed by the trolley conveyor The conveyer is controlled to lift the cake to take out the cake, the transfer mechanism is controlled to transfer the cake taken out by the takeout conveyor onto the pallet of the pallet conveyor, and further, the cake conveyed by the pallet conveyor. And a control device for controlling the mounting mechanism so that the cake is mounted on the holder of the creel stand.

The present invention is also practiced by arranging the above-described device on both sides of a creel stand positioned.

[0008]

[Action] The cake conveyed by the trolley conveyor is detected, the take-out conveyor is raised, and the take-out conveyor is initially driven at the same speed as the trolley conveyor in the same direction to slightly lift the cake conveyed by the trolley conveyor. Then, the cake conveyed by the trolley conveyor is pulled out from the support rod, taken out and lowered by gradually increasing the speed of the take-out conveyor and driving it at a speed higher than the conveying speed of the trolley conveyor. Then, the cake taken out by the take-out conveyor is transferred onto the pallet of the pallet conveyor by the transfer mechanism. Further, the cake conveyed by the pallet conveyor is mounted on the holder of the creel stand by the mounting mechanism.

By arranging the above devices on both sides of the creel stand, cake mounting work can be performed simultaneously on both sides of the creel stand, thereby improving work efficiency.

Further, as shown in FIG. 4C, racks (4j) and (4j) which are engaged with one pinion (4i) are attached to the expansion and contraction plates (4e) and (4e). ) Is reciprocated by the expansion / contraction cylinder (4k) via the drive rack (4m) to open / close the four chuck claws (4a) by operating the pair of expansion / contraction plates (4e) and (4e). To make it work.

When the transfer mechanism (4) receives the cake (1) from the take-out conveyor (3), the transfer mechanism (4) operates the chuck claws (4).
a) is advanced horizontally in an open state, and then the chuck claw (4a) is closed and the periphery of the cake (1) is gripped at four points while slightly lifted from the take-out conveyor (3);
It retreats horizontally and retreats from the end of the take-out conveyor (3) to a position where it does not interfere, and then turns 90 ° to grip the cake (1) vertically in a downward direction. The cake (1) is transferred onto the pallet (5a) of the pallet conveyor (5) by the downward forward movement of the pallet conveyor (5), and the chuck jaws (4a) are opened to ascend (upward and backward movement of the forward / backward cylinder (4h)). And return to a horizontal state to prepare for the transfer of the next cake (1).

The pallet conveyor (5) has a frame (5)
