Description

Technical Field

[0001] The present invention relates to the technical field of textile machinery, and in particular to a transfer device for empty fabric shafts, an electronic fabric production system, and a method for transferring empty fabric shafts. Background Art

[0002] The process of fabric dropping and installing empty fabric shafts: In the fabric weaving section of a fiberglass electronic fabric production workshop, an empty fabric shaft needs to be installed on a loom, and then the loom starts to weave. The fabric is wound onto the empty fabric shaft. After weaving is completed, a semi-automatic fabric dropping vehicle or a fully automatic fabric dropping vehicle / AGV pulls the fabric roll (including the fabric roll shaft) to the fabric dropping station to put down the fabric, and then transfers it to the next process for post-treatment. Then, the fabric dropping vehicle goes to the empty fabric roll shaft station to transport the empty fabric roll shafts transported from the fabric post-treatment workshop to the loom for weaving.

[0003] Since the efficiency of the empty fabric roll shafts provided for and required by post-treatment and fabric weaving does not match, a buffer is needed at the interface between the two processes. Currently, several empty fabric shafts are placed in an empty fabric shaft tray rack, an empty fabric shaft cage, or an empty fabric shaft basket, and when the fabric dropping vehicle goes to pick up the empty fabric shafts, they are manually carried onto the fabric dropping vehicle.

[0004] It can be seen that the existing process of empty fabric shaft transfer requires manual participation, consuming a lot of labor, and cannot achieve the upgrading of production automation and unmanned processes, resulting in limited expansion of production capacity. Summary of the Invention

[0038] To make the objectives, technical solutions and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other implementation manners obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope protected by the present invention.

[0039] As shown in Figure 1 the figure, the present invention provides a transfer device for empty spindles in weaving, including a cantilever docking platform 1. The docking platform 1 includes a frame and a conveying mechanism, and the empty spindle 2 can be placed on the conveying mechanism for transmission.

[0040] By using the conveying mechanism of the cantilever docking platform 1 to convey the empty spindle 2, the transfer of the empty spindle 2 does not require manual participation, saving labor and facilitating the realization of production automation and the upgrade of unmanned processes; moreover, the transfer device for empty spindles in weaving has a certain buffering capacity, which can adjust the supply and demand balance of the empty spindle 2 between weaving and post-treatment, and the electronic fabric production system can operate quickly and smoothly.

[0041] The docking platform 1 is set as a cantilever type, which is convenient for the operation of the forklift 8 and the pallet rack 3 and is not prone to interference.

[0042] As an optional implementation manner, as shown in Figure 2 the figure, the frame includes a bracket 12 and two cantilever beams 13 arranged side by side on the bracket 12, and the conveying mechanism is arranged on the cantilever beams 13.

[0043] It should be noted that by using two cantilever beams 13 arranged side by side to support the conveyor chain 11, the empty spindle 2 is not easily dropped and displaced, and the transmission reliability is high.

[0044] As an optional implementation manner, as shown in Figure 2 the figure, the conveying mechanism includes a driving member 5, a conveyor chain 11 and a positioning structure 4. Multiple groups of positioning structures 4 are installed at intervals on the outer side of the conveyor chain 11 to limit and fix the empty spindle 2, and can rotate multiple empty spindles 2 at the same time and can play a certain buffering role; the conveyor chain 11 is arranged on the cantilever beam 13 and is in transmission connection with the driving member 5. Specifically, in this embodiment, the driving member 5 adopts a motor, and the motor drives two conveyor chains 11 to rotate synchronously, and controls the rotation direction of the conveyor chain 11 through the forward and reverse rotation of the motor, so as to realize the reciprocating movement of the positioning structure 4.

[0045] In other implementation manners, the conveyor chain 11 can be replaced by a linear moving device such as a belt conveying device.

[0046] As an alternative implementation, each set of positioning structures 4 includes two positioning blocks, and a positioning space for accommodating the empty shaft 2 is formed between the two positioning blocks. A clamping and positioning space is formed between the two positioning blocks, which facilitates the limitation of the empty shaft 2.

[0047] As Figure 3 and Figure 4 As shown, the two positioning blocks of each set of positioning structures 4 each have a positioning inclined surface that inclines towards the inner side of the positioning space, forming a V-shaped support structure. The V-shaped support structure can prevent the empty shaft 2 from coming out and shifting, and has a good positioning effect.

[0048] Figures 5 - 7 The following gives the fork placement process for the empty shaft pallet rack with an empty shaft. The pallet rack 3 is sent under the cantilever beam 13, the fork 8 descends, the empty shaft 2 remains on the platform, and the fork 8 retracts to remove the empty pallet rack 3.

[0049] As an alternative implementation, the cantilever beam 13 includes a fixed end and a suspended end, and the suspended end is located at one end of the cantilever beam 13 away from the support 12. The fixed end is fixedly installed on the support 12, and the suspended end is located at one end of the cantilever beam 13 away from the support 12, which facilitates the fork 8 to enter the space below the cantilever beam 13 for the operation of loading the empty shaft 2.

[0050] As an alternative implementation, the empty shaft transfer device for woven fabric also includes a detection device for detecting the presence of the empty shaft 2. The detection device is fixed at a position on the cantilever beam 13 close to the fixed end, which facilitates detecting whether there is an empty shaft 2 at the unloading position of the docking platform 1, so as to control the driving member 5 to drive the conveyor chain 11 to rotate and / or send a signal indicating that an empty shaft can be taken and a signal for receiving an empty shaft.

[0051] Specifically, the detection device is a photoelectric switch (diffuse reflection switch 7) or a proximity switch 6, as well as a travel switch of the conveyor chain 11, that is, a chain position switch for receiving the empty shaft pallet. Using a photoelectric switch or a proximity switch 6, the response is fast and accurate.

[0052] The present invention also provides an electronic cloth production system, including a pallet rack 3 and the above-mentioned empty shaft transfer device for woven fabric. Refer to Figure 5 , Figure 6 and Figure 12 . After adopting the empty shaft transfer device for woven fabric of the present invention, the automated production of the electronic cloth production system is realized, and the production efficiency is improved. It should be noted that multiple sets of empty shaft transfer devices can be set according to the production capacity.

[0053] The present invention also provides an empty shaft transfer method for transferring the empty shaft 2 of the above-mentioned electronic cloth production system. The method includes:

[0054] S1. The fork 8 picks up the pallet rack 3 carrying the empty shaft and places the empty shaft 2 at the loading station of the docking platform 1;

[0055] S2. Move the pallet rack 3 away, operate the conveying mechanism, and convey the empty shaft 2 to the blanking station of the docking platform 1;

[0056] S3. The cloth-falling vehicle 200 moves the empty shaft 2 away from the blanking station.

[0057] Specifically, the transfer process of the empty shaft 2 is as follows: The conveyor chain 11 of the docking platform 1 reaches the position on the left side where the pallet rack 3 for receiving the empty shaft 2 can be connected (loading position) - the empty shaft 2 transfer device of the weaving machine sends a signal allowing the pallet rack 3 of the empty shaft 2 to enter - the forklift 8 picks up the pallet rack 3 of the empty shaft 2 and places the empty shaft 2 on the docking platform 1 - the pallet rack 3 is moved away - the conveyor chain 11 turns right - triggers the switch for detecting the empty shaft 2 on the rightmost side, and the conveyor chain 11 stops - the empty shaft transfer device of the weaving machine sends a signal that the empty shaft 2 can be taken - the cloth-falling vehicle 200 comes to pick up the empty shaft 2 - the switch detects that there is no empty shaft 2 on the rightmost side and there is an empty shaft 2 on the platform (that is, there is no goods signal on the rightmost side and there is an empty shaft 2 detected at the second position from the right) - the conveyor chain 11 continues to turn right until the empty shaft 2 is detected on the rightmost side and a signal that the empty shaft 2 can be taken is sent, and the above actions are repeated - after detecting that there is no empty shaft 2 on the platform, the conveyor chain 11 turns to the leftmost side and sends a signal that an empty shaft pallet can be received. For the transfer state of the empty shaft 2, see Figures 8 - 11 , and the cloth-falling vehicle 200 picks it up from the right side in the figure. After the empty pallet rack 3 is taken away, the conveyor chain 11 rotates, driving the empty shaft 2 to move to the right until it moves to the outermost side. After the cloth-falling vehicle 200 picks up the outermost empty shaft 2, the conveyor chain 11 continues to turn right until there is no empty shaft 2 on it. Then the conveyor chain 11 turns to the left, and the positioning structure 4 moves to the left side to wait for the empty shaft pallet rack transferred by the empty shaft pallet truck 100 to come and place the empty shaft 2.

[0058] Using the empty shaft 2 transfer method of the present invention, the automatic docking of the cloth-falling vehicle 200 and the empty shaft pallet is realized, and it has a certain buffering effect, which can balance the efficiency imbalance between the two processes.
