[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for mounting a cake after a twisting machine on a trolley conveyor.

[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 attached to a creel stand with casters by a worker and transported to a place where a tire cord loom is installed.

[0003] The cake for tire cord is required to have an increased amount of wound yarn, and accordingly, the weight of the cake is 10 to 15 kg, and the cake after the ply twisting machine is handed to the creel stand. In the conventional method of mounting by work, the labor burden on the operator becomes excessive, and also a large amount of labor is required to transport the creel stand with casters from the position of the plying machine to the installation location of the tire cord loom. Labor saving of these is demanded.

As means for transporting these cakes, for example, a trolley conveyor may be employed. However, a conventional apparatus for mounting cakes after the twisting machine onto the trolley conveyor is a fixed type for each machine. A transfer device was installed.

[0005]

Generally, in this kind of twisting machine, a plurality of twisting machines are arranged with a spindle row in parallel.
The doffing point of the full cake is usually different for each machine, and as in the past, in a configuration in which a fixed transfer device is installed for each machine, even if labor saving can be achieved, There was a disadvantage that the capital investment for that purpose increased significantly.

The present invention has been proposed in view of these drawbacks, and an object thereof is to carry out equipment investment at a low cost and to mount a cake from a ply twisting machine on a trolley conveyor. An object of the present invention is to provide a device that does not contaminate the rolled layer of the cake, can prevent collapse of the roll, has a small structure, is simple, inexpensive, and is easy to handle.

[0007]

In order to achieve the above object, the present invention relates to a cake delivery conveyor for intermittently carrying out a cake which has been raised from a twisting machine while keeping its axis parallel to the carrying-out direction; A support rod that is installed above the end of the unloading conveyor at right angles to the transport direction and is inserted into the bobbin of the cake to support and transport the cake substantially horizontally is parallel to the transport direction, with the free end at the free end and the rear end at one end. A trolley conveyor that is supported and held at equal intervals in a holding state, an elevator that is installed on the main frame so that it can be moved up and down between the end position of the cake unloading conveyor and the position of transferring the cake to the trolley conveyor, A swivel that can be turned 90 ° while the table is moving up and down, and a horizontally installed on the swivel, in the same direction as the cake unloading conveyor when receiving cake from the cake unloading conveyor Moved to receive the cake, temporarily stopped after receiving, when transferring the cake to the trolley conveyor, the transfer conveyor that can be driven in the same direction as the trolley conveyor, and when the transfer conveyor returns to the cake receiving position, The unloading conveyor and the transfer conveyor are driven, and when the transfer conveyor receives the cake from the cake unloading conveyor, the cake unloading conveyor prepares the next cake to be unloaded and waits, and the transfer conveyor is stopped. Raise the elevating platform, rotate the swivel platform 90 degrees on the way to make the axis direction of the cake on the transfer conveyor coincide with the transport direction of the trolley conveyor, and then confirm that the support rod of the trolley conveyor is empty. After confirming, raise the elevator further, and in this state, drive the transfer conveyor in the same direction as the trolley conveyor, and use the support rod to move the transfer conveyor. The upper cake is received by the support rod, and thereafter, the elevating table is lowered, a 90 ° swivel return operation is performed on the way, and further lowered to return the transfer conveyor to the cake receiving position, and thereafter, this operation is repeated. It is provided with a control means for controlling so as to provide a device for mounting the cake on the trolley conveyor of the cake after the ply twisting machine, which can be positioned and moved to the end position of the cake carry-out conveyor of each ply twister via the main body frame. is there.

Further, according to the present invention, the turning direction of the swivel base can be selected between left and right.

[0009]

The cake produced by the twisting machine is doffed on a cake carry-out conveyor and sequentially conveyed to a transfer conveyor. The cake conveyed to the transfer conveyor is
The elevator is raised toward the trolley conveyor by the elevating platform, and on the way, the swivel platform is rotated by 90 ° together with the transfer conveyor, so that the axial direction matches the transport direction of the trolley conveyor. Then, after confirming that the supporting rod of the trolley conveyor is empty, the elevator is further raised, and the cake is raised to the receiving position of the trolley conveyor. In this state, the transfer conveyor is driven in the direction of transport of the trolley conveyor, the traveling support rod enters the bobbin center hole of the cake, and the support rod and the cake are moved in the same direction to transfer the cake. When the cake is taken away by the support rod, the cake is rubbed on the transfer conveyor to prevent dirt from adhering and to prevent the cake from rolling. Then, when the cake is delivered to the support rod of the trolley conveyor, the lifting platform descends, the transfer conveyor is stopped,
During the downward movement, the transfer conveyor rotates 90 ° together with the swivel table, returns, and returns to the cake receiving position. Thereby, the cake carry-out conveyor and the transfer conveyor are driven, when the cake is transferred onto the transfer conveyor, the cake carry-out conveyor waits to prepare for carrying out the next cake, and the transfer conveyor is stopped, The lift is raised, and the above operation is repeated thereafter.

[0010] The twisting machine usually has two rows of spindles arranged in front and rear, and a cake unloading conveyor is installed in the middle between them, and the doffing of the cake which has become full is different between the front row and the rear row at different times. At the same time, the tail yarn of the cake (the end of the yarn wound by the plying machine) is reversed in the front and rear rows (for example, if the front row is wound clockwise, the rear row is If the direction of the tail yarn of the cake is reversed in the front row and the back row, the cake is supported and transported by the support rod of the trolley conveyor, and the loom for tire cords is wound. When the creel is mounted on the creel, the direction in which the yarn is pulled out is reversed between the front line and the rear line, and there is a problem that the yarn is not properly drawn out or the yarn breaks. Therefore, the present invention, when rotating the transfer conveyor 90 ° together with the swivel table on the elevating table, so that the left and right of the front row and the rear row can select the turning direction, thereby, the trolley conveyor The direction of the tail thread of the cake when transported by the support rod can be aligned in the same direction.

A plurality of twisting machines are usually arranged with the spindle rows parallel to each other. However, the doffing point of the full cake is usually different for each machine. The apparatus can be positioned and moved to each machine, thereby sharing one machine with each machine.

Therefore, according to the present invention, when the transfer conveyor (8) is rotated by 90 ° together with the swivel base (7) on the lift base (6), the swivel direction of the front row and the rear row can be selected from left and right. Thus, the tail yarns of the cake (1) can be aligned in the same direction when they are conveyed by the support rods (4) of the trolley conveyor (3).

In the plying machine, a plurality of ply twisting machines are usually arranged with their spindle rows parallel to each other. However, the doffing time of the full pipe cake is usually different for each machine. The device can be positioned and moved on each machine base, and thus one device can be shared by each machine base.

[0026]

According to the present invention, since it can be positioned and moved to the end position of the cake carry-out conveyor of each ply twisting machine through the main body frame, it can be shared by each machine stand by one device. The cost can be significantly reduced. Then, the cake produced by each plying machine can be automatically and sequentially mounted on the supporting rod of the trolley conveyor,
In addition, the transfer conveyor is driven in the direction of transport of the trolley conveyor, the traveling support rod is advanced into the bobbin center hole of the cake, and the support rod and the cake are moved in the same direction, and the impact at the time of cake delivery is performed. When the cake is removed by the support rod, the cake can be prevented from rubbing on the transfer conveyor, thereby preventing dirt from adhering and causing collapse.

Further, according to the present invention, when the transfer conveyor is rotated by 90 ° together with the revolving base on the lifting table, either the right or left direction of the rotation can be selected, so that the supporting rod of the trolley conveyor can be used. The bottom threads of the cake can be oriented in the same direction.
