In this case, the thread may rub against the edge of the opening of the panel and the panel may be damaged.

  Then, an object of this invention is to provide the spinning unit and spinning machine which can suppress that a panel gets damaged.

  The spinning unit of the present invention includes a yarn supply device that supplies yarn, a yarn storage roller that stores the yarn supplied from the yarn supply device, and an outer side of the machine base relative to the yarn storage roller. A panel formed with an opening that is exposed to the outside, and the panel includes a main body part and an edge part that forms an edge of the opening, and at least a part of the edge part is higher than the hardness of the main body part It has at least one of physical properties of hardness, a melting point higher than the melting point of the main body, and a surface roughness smaller than the surface roughness of the main body.

  When removing the yarn entangled with the yarn accumulating roller, if the yarn is rubbed against the edge of the opening in the panel (hereinafter also simply referred to as “edge”), the following knowledge is found. That is, it is found that by increasing the hardness of the edge portion, the edge portion is hardly damaged. It is found that by increasing the melting point of the edge part, the edge part is hardly melted by heat generated by rubbing the yarn, and the edge part is hardly damaged. It has been found that by reducing the surface roughness of the edge, the edge is less likely to be scratched. Therefore, in the spinning unit of the present invention, at least a part of the edge portion has a hardness higher than the hardness of the main body, a melting point higher than the melting point of the main body, and a surface roughness smaller than the surface roughness of the main body. It has at least one of the physical properties. Thereby, even when a thread | yarn rubs against an edge part, it becomes possible to suppress that a panel is damaged.

  In the spinning unit of the present invention, at least a part of the edge portion may include at least one of one side edge portion on one side in the horizontal direction and the other side edge portion on the other side in the horizontal direction. When removing the yarn entangled with the yarn accumulating roller, it is found that the yarn is particularly rubbed at the one side edge portion in the horizontal direction or the other side edge portion in the horizontal direction among the edge portions. Then, the effect which suppresses that a panel is damaged becomes remarkable by including at least one of the said 1 side edge part and the said other side edge part in the edge part which has the physical property mentioned above.

  In the spinning unit of the present invention, at least a part of the edge portion may include a corner portion or a chamfered portion that forms an edge of the opening outside the machine base.

Thus, the structure which an edge part has the physical property mentioned above is easily realizable by using the edge member different from a main-body part. Further, even if at least a part of the edge is damaged, it can be dealt with by replacing the edge member.

  The spinning unit of the present invention may include a frame to which a panel is attached, and the edge member may be sandwiched between the main body portion and the frame. According to this configuration, the edge member can be reliably fixed. In addition, fixing tools such as screws for fixing the edge member can be reduced, and as a result, the number of assembly steps can be reduced.

  In the spinning unit of the present invention, the edge member may extend in an arch shape along the opening as viewed from the outside of the machine base, and may be fixed to the outside of the machine base of the main body by bonding. In this case, the configuration in which the edge has the physical properties described above can be easily realized by using, for example, a panel of an existing spinning unit.

  The spinning unit of the present invention may include a clamping member that is fixed to the main body portion and sandwiches at least one of the one end portion and the other end portion of the edge member extending in an arch shape in cooperation with the main body portion. According to this structure, it can prevent that at least any one of the one end part and other end part of an edge member leaves | separates with respect to a main-body part.

The plurality of spinning units 2 are arranged in a line. Each spinning unit 2 generates the yarn Y and winds it on the package P. When the yarn Y is cut by a certain spinning unit 2 or the yarn Y is cut for some reason, the yarn joining cart 3 performs a yarn joining operation with the spinning unit 2. The doffing cart doffs the package P and supplies a new bobbin B to the spinning unit 2 when the package P is full in a spinning unit 2.

  In the following description, in the path along which the yarn Y travels (that is, the yarn path), the side where the yarn Y is generated is referred to as “upstream side”, and the side where the yarn Y is wound is referred to as “downstream side”. The side on which the yarn path is located with respect to the yarn joining cart 3 is referred to as “front side” or “front side”, and the opposite side is referred to as “rear side”. The upper side in the vertical direction is simply called “upper side”, and the lower side in the vertical direction is simply called “lower side”.

  The first end frame 4 accommodates a collection device for collecting fiber waste and yarn waste generated in the spinning unit 2. The second end frame 5 adjusts the air pressure of the compressed air (air) supplied to the spinning machine 1 to supply air to each part of the spinning machine 1 and supplies power to each part of the spinning unit 2. A drive motor or the like is stored. The second end frame 5 is provided with a machine control device 51, a display screen 52, and input keys 53. The machine control device 51 centrally manages and controls each part of the spinning machine 1. The display screen 52 can display information related to the setting contents and / or status of the spinning unit 2. When the operator performs an appropriate operation using the input key 53, the setting operation of the spinning unit 2 can be performed.

  Each spinning unit 2 includes a draft device (yarn feeding device) 6, an air spinning device (yarn feeding device) 7, a yarn monitoring device 8, a tension sensor 9, and a yarn in order from the upstream side in the running direction of the yarn Y.
