Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention is similar to a spinning machine or a twisting machine, in which the machine is Regarding the spindle drive mechanism in a spinning machine equipped with a large number of arranged spindles Ru.

0002

[Conventional technology]

The spindle drive method in these spinning machines uses a drive motor to drive the spindle. An endless belt runs tangentially along the spindle row, and the warp between this and the spindle A so-called tangential drive that rotates the spindle by contact with There is a method.

0003 An example of this, the group tangential drive method, is shown in Figures 2(a) and (b). To explain based on The drive shaft is divided into multiple sets according to the arrangement order in the direction, and the drive shaft is oriented vertically for each set. A motor 2 is provided, and an endless belt 3 driven by the motor 2 is connected to the end region of each set. Wrap it around two pairs of guide pulleys 4, 4'; 5, 5' provided in the It is brought into contact with the warb of the spindle 1 in the tangential direction and is driven to rotate. In this method , since the length of the belt is relatively short, it is easy to adjust the contact pressure with the spindle warb. It is easy to use and can give even rotation to the spindles in the set.

0004 Furthermore, in order to prevent differences in spindle rotational speed between each set, The two sets of guide pulleys 4, 4' are sequentially connected to the adjacent set of guide pulleys 5, 4'. 5'. Therefore, the surface of each pair of guide pulleys is , as shown in Fig. 2(b), two sets of spindles are driven respectively. The book belts 3, 3' are wrapped around the pulley surface in parallel in the height direction. Become.

[0005]

[Problem that the idea aims to solve]

For this reason, as shown in FIG. 3, one set of spindles 1 is and the other set of spindles 1 contacts another belt in the lower region of the weave 6. An offset run is performed in which the vehicle contacts the tip 3'. This means that both or at least On the other spindle, the contact pressure of the belt is applied to the neck supporting the spindle. It means that it is applied at a position away from the bearing 7, and the motor is applied to the bearing. act on the spindle and shorten its life or cause failures such as tilting the spindle. Ru.

[0006] This invention solves the problems of the conventional technology and eliminates belt offset running. Even in the group tangential drive method used, the spindle net We propose a spindle drive mechanism that applies the correct belt contact pressure to the shaft bearing. The purpose is to

[0007]

[Means to solve the problem]

The purpose is to arrange the spindles in parallel on both sides of the spinning machine in the longitudinal direction. The motor is divided into multiple groups according to At the same time, the endless belt driven by this is driven by two Wrap it around a pair of guide pulleys, and use the guide pulley for both adjacent sets. Two sets of belts are run offset from each other, and this is applied to the warp of each spindle. Group tangential drive method that rotates by contacting in the tangential direction When the spindles of one set next to each other are installed on the machine base, The height position of the neck bearing in the insert that supports rotation of the blade is higher than that of the other assembly. to occupy a predetermined position different from the height position of the neck bearing of the spindle. and the belts of each set are connected to the neck belts of the spindles in that set. is positioned to run in contact with the area of the warb that corresponds to the position of the ring. This is achieved by a spindle drive mechanism characterized by:

[0008]

[Effect] The spindle used in this invention is Two types of molds are prepared, and each is attached to the frame of the spinning machine as an adjacent set. Ru. When the belt is run offset by a motor provided for each set, Each belt is attached to a corresponding set of spindle warbs, neck bearing height Make contact in the area corresponding to the position. Therefore, the neck bearing has no contact with the belt. Undesirable moments due to pressure are avoided and the spindle circle Smooth rotation is guaranteed.

[0009] Hereinafter, the present invention will be explained in more detail based on preferred embodiments shown in the drawings.

0010

【Example】

The spindle used in this invention is a spinning machine, as shown in Figures 1(a) and (b). When fixed to the spindle rail 12, the spindle blade 10 is rotationally supported. The height position of the neck bearing 7 of the insert 11 is classified into two types. It will be done.

[0011] In one spindle 1a, the neck bearing 7 is attached to the spindle rail 1. It is set to occupy a position at a height m from the top surface of the other spindle 1b. In other cases, it is set to occupy a lower n position than this. In order to change the height position of the neck bearing 4 in this way, insert 11 is Bolster 13 for receiving, insert of the part protruding above the bolster 13 11 and a pedestal 15 are attached to the spindles 1a and 1b. They are prepared as parts of different standards with different lengths.

0012 Of course, it is inserted into the tip of the blade 2 and fixed above the spindle warb 6. The sleeve 14 is of the same size for both, and the height of the spindle as a whole is The values of H are set to be the same. The two types of spindles 1a and 1b prepared in this way each have an adjacent pair. A predetermined number of pieces are arranged and fixed on the spindle rail 12 so as to form a structure. 2, with substantially the same configuration as that already described based on FIG. 2 as the prior art. , the belt 3 is wound around the guide pulley and driven by the motor 2. A loop tangential drive is performed.

[0013] As mentioned above, the belts 3 and 3' driving adjacent sets of spindles are connected to a common belt. Offset travel across areas with different heights on the surface of the idle pulley. In this invention , spin so that the neck bearing 7 is aligned with the running height of this belt. Since the belts 1a and 1b are installed, each belt 3 and 3' is attached to the neck bearing 7. It is possible to travel in the area of the corresponding warb 6 and apply vertical contact pressure to it. Wear.

[0014]

[Effect of the idea]

According to the present invention, spindles attached to a spinning machine are divided into groups of a predetermined number, and The neck bearings of matching pairs of spindles are configured to have different height positions. Therefore, in the case of a group tangential drive where the belt runs offset However, the belt always has a warp corresponding to the height position of the neck bearing of the spindle. Contact pressure can be applied to the area. This creates an extra moment in the bearing. This ensures smooth rotation of the spindle and has a longer lifespan.
