Description

Technical Field

[0001] The utility model relates to a can processing assembly for a spinning preparation machine, and more specifically, to a can processing assembly for a spinning preparation machine, such as a drawing frame, a carding machine, a carding machine with a drafting unit, a combing machine, etc. Background Art

[0002] In textile fiber processing machines such as drawing frames, carding machines, cards with drafting units and combing machines, a drawn fiber band called sliver is deposited in a can located in a sliver filling station via a winder and a turntable. In general, the sliver filling station comprises a can handling assembly, which comprises: a turntable rotatable about a vertical platform axis for rotating the cans standing thereon; a can changer for moving empty cans onto the platform and moving filled cans off the platform; and a center positioning device for centering the cans on the platform relative to the platform axis.

[0003] In the known can handling arrangement of a textile spinning preparation machine, the diameter size of the can supplied to the machine is 400 mm to 800 mm. In the drawing frame, a can filling can is placed under the winding machine arrangement at the conveying area, the winding machine rotates around a vertical axis, and the can filling can rotates with its own axis, thereby filling the can into the can. Then, the filled can is replaced with an empty can. Normally, an empty can is provided as a spare can before the filling can along the direction of the can running. In the conventional linear can changer type for the drawing frame, two spare cans are placed before the filling can in a linear path or sometimes in an "L" path along the length of the machine. This type of drawing frame has a platform / foot pedal on the side of the frame to allow workers to view or handle the drafting area on the top. The first spare can is placed in an empty space behind the filling can. In addition to the first spare can, the second spare can is located behind the first spare can and is thus located between the frames. The line connecting the centers of the filling can, the first spare can and the second spare can is generally a straight line in the direction of the can running. This prior type of reserve can arrangement requires more space to hold the reserve cans, which increases the length and overall footprint of the machine. These cans take up floor space of their own size, making the preparation machine longer.

[0004] For example, in spinning mills, double-head drawing frames are used to increase production and save floor space. The cylinder change arrangement used in these known machines is of linear type or rotary type. Under any conditions, at least two spare cylinders are provided in the machine before the strip filling cylinder. In the linear type, the first empty spare cylinder is arranged behind the filling cylinder, and the second spare cylinder is arranged transverse to the first spare cylinder position. The cylinder change arm is used together with a linear actuator or a motor drive to shift the spare cylinder to the filling position. On the spinning mill floor, the total floor space occupied by these machines of this type (linear type) is generally about 22 to 25 square meters. In the case of the rotary cylinder change type, a motor drive and a cylinder change arm are generally used to move the spare cylinder to the filling position. The total floor space occupied by these rotary cylinder changer type (rotary type) machines generally reaches about 40 to 43 square meters. Therefore, all the known types of machines occupy a total floor space of 22 square meters to 43 square meters as the machine area. In order to reduce the floor space of the machine, the utility model provides a solution by changing the position of the spare cylinder adjacent to the foot pedal in the same area.

[0005] The utility model to be disclosed reduces the total floor space of a textile spinning preparation machine and reduces the layout area under the condition of arranging the same number of spare cans and drives for the can changing process. Utility Model Content

[0006] The main purpose of the utility model is to provide a can processing component which can reduce the floor space of the existing spinning preparation machine.

[0007] Another object of the present invention is to provide a can arrangement which reduces the overall footprint of a textile spinning preparation machine compared to existing arrangements.

[0008] Yet another object of the present invention is to provide an improved layout for a textile spinning preparation machine which allows the operator free access to the drafting area and the take-up station to a certain extent.

[0009] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a can handling assembly for a spinning preparation machine is disclosed. The can handling assembly includes: a filling station, which is arranged together with a winder area; a main spare can station, which is arranged behind the filling station in the running direction of the can; and a secondary spare can station, which is arranged adjacent to the main spare can station in a transverse direction transverse to the running direction of the can. At least one rotating arm arrangement is provided to move the empty can from the secondary spare can station to the main spare can station by a first drive arrangement. At least one linear arm arrangement is provided to move the empty can from the main spare can station to the filling station by a second drive arrangement.

[0010] In order to achieve the above-mentioned object, according to one aspect of the utility model, a can handling assembly for a spinning preparation machine is disclosed. The can handling assembly comprises: at least one rotating arm arrangement, which is suitable for moving the empty can from the secondary standby can station to the primary standby can station in a direction transverse to the running direction of the can through a first drive arrangement; and at least one linear arm arrangement, which is suitable for moving the empty can from the primary standby can station to the filling station in a direction consistent with the running direction of the can through a second drive arrangement.

[0011] The spinning preparation machine with the can handling assembly has a reduced footprint compared to existing arrangements. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Figure 1 A textile spinning preparation machine, for example a draw frame according to the invention, is shown.

[0013] Figure 2 and Figure 3 An isometric view of a can handling assembly of a textile spinning preparation machine according to the present invention is shown. DETAILED DESCRIPTION

[0014] According to a preferred embodiment of the present invention, Figure 1 The can handling arrangement of a textile spinning preparation machine 1, such as a double-conveying drawing frame, is shown in FIG. The textile spinning preparation machine according to the invention can be not only a drawing frame, but also a carding machine, a carding machine with a drafting unit, a combing machine, an autoleveling drawing frame, a non-autoleveling drawing frame, etc. (as long as the can change occurs therein). Figure 1 A top view of the creel feed area (C1) of a textile preparation machine (e.g. a drawing frame) is shown, in which a plurality of 600 mm diameter strip cans 1a, 1b, 1c, 1d, 1e, 1f, 1g, 1h, 1i, 1j, 1k, 1l, 1m, 1n, 1o, 1p are placed. A suction arrangement is provided near the strip supply area 2. The drafting area 3 is located above the suction arrangement. An electrical distribution box is arranged near the strip filling station. The strips from each can (1a to 1p) pass through a strip guide to the strip supply area 2. Subsequently, the supplied strips are transferred to the strip conveying area. After processing, the strips are transferred to the strip filling can 4 (e.g. a winding unit or a winding machine station) via a winding unit. Figure 2 ). Figure 3 The filled strip can 4 shown in the figure is replaced by an empty strip reserve can 5 placed behind the strip filling can 4. According to the invention, the second reserve can 5' is placed adjacent to the first reserve can, so that a line (not shown) connecting the centers of the first and second reserve cans is substantially transverse to the strip running direction X. In other words, a line connecting the centers of the filling can 4 and the first reserve can and a line connecting the centers of the first and second reserve cans 5' are substantially at right angles.

[0015] In addition, the second spare drum or empty drum 5' is accommodated in the space of the secondary spare drum station R2 located between the foot pedal area. The foot pedal allows the operator to enter the reeling unit for any maintenance work if necessary. The foot pedal arranged on the side of the suction arrangement serves as a space for the operator to enter the strip feeding area 2 containing the drafting arrangement and / or the drive area 3. If necessary, the operator can freely enter the drafting arrangement from the foot pedal area to perform any maintenance work.

[0016] like Figure 2 and Figure 3 As shown, the can handling assembly according to the present invention has at least one rotating arm arrangement L2, which is used to move the empty can 5 from the secondary standby can station R2 to the main standby can station R1 through the first drive arrangement (D1). The first drive arrangement D1 is actuated, and the rotating arm L2 fixed to the rotary actuator moves the spare empty can 5 from the secondary standby can station R2 to the main standby can station (R1) along a direction (Y) transverse to the can running direction. After changing the can, the rotating arm L2 remains within the machine width, thereby reducing the total footprint of the machine.

[0017] Furthermore, a linear arm arrangement L1 is provided for moving the empty cans 5 from the main reserve can station R1 to the filling station F1 by means of a second drive arrangement D2. After the empty cans 5 have reached the main reserve can station R1, the linear arm arrangement L1 is actuated by means of the second drive arrangement D2. Thus, the linear arm arrangement L1 pushes the filled cans 4 from the filling station F1 to the can delivery area by means of the arm arrangement and returns to the initial position for the next operating cycle. Thus, the combined mechanism of the linear arm arrangement L1 and the rotary arm arrangement L2 reduces the overall size of the machine and reduces the footprint of the machine preferably to 18 to 20 square meters.

[0018] According to one aspect of the invention, the can handling assembly in the spinning preparation machine comprises at least one first drive arrangement D1 configured to drive the rotating arm arrangement L2. The first drive arrangement preferably comprises an electric motor, a pneumatic drive, a hydraulic drive or the like.

[0019] According to yet another aspect of the invention, the can handling assembly in the spinning preparation machine comprises at least one second drive arrangement D2 configured to drive the linear arm arrangement L1. The second drive arrangement preferably comprises an electric motor, a pneumatic drive, a hydraulic drive or the like.

[0020] According to another aspect of the invention, a can handling assembly in a spinning preparation machine comprises a swivel arm arrangement L2 which is pivotally mounted to a can changer structure. Thus, the entire machine structure becomes an integrated assembly providing structural rigidity. Thus, the entire assembly can be repositioned or transferred to an installed position without disassembly.

[0021] According to another aspect of the invention, the can handling assembly in the spinning preparation machine comprises that the rotating arm arrangement L2 is provided with elbow arms and guide rollers for can handling. The can handling assembly in the spinning preparation machine comprises a linear arm arrangement L1 provided with arms and guide rollers for can handling. According to this arrangement, the total footprint (WxH) of the machine is preferably reduced to a range of 18 to 20 square meters, which provides a huge saving impact in terms of space from a factory perspective.

[0022] Other aspects and advantages of the present invention will become apparent from the following description taken in conjunction with the accompanying drawings, which illustrate by way of example the principles of the present invention.

[0023] Considering the present disclosure describing the present utility model, all changes, modifications and variations within the meaning and scope of equivalents are considered to be within the scope and spirit of the present utility model. It should be understood that the various aspects and embodiments disclosed above can be used in any combination with each other. Multiple aspects and embodiments can be combined together to form further embodiments of the present disclosure.
