Description

Technical Field

[0001] This utility model relates to a feeding device, and more particularly, to a material transfer mechanism. Background Technology

[0002] Currently, sewing equipment for fabric typically combines a sewing machine with a fabric placement plate. The sewing machine, responsible for the main processing, is mounted on the fabric placement plate, which can be relatively large. The operator can place the first piece of fabric in a batch flat on the plate and manually push it into the sewing head position of the sewing machine, where it will begin sewing.

[0003] To solve the problem of manually transferring fabric, some manufacturers use a liftable pressure plate to hold down the fabric piece that has been placed flat on the fabric placement plate. Then, other drive structures drive the pressure plate to move horizontally until the pressure plate drags the fabric to the sewing head of the sewing machine for processing.

[0004] While the above structure can solve the problem of manually dragging the fabric in the first step, if it relies solely on a single drive structure and the cooperation of the pressure plate, even if the first piece of fabric is automatically dragged to the sewing head of the sewing machine by the pressure plate for sewing, and the operator has already placed the second piece of fabric flat on the fabric placement plate, the pressure plate is still driving the first piece of fabric to feed, and cannot promptly drag away the second piece of fabric that has been placed flat. In the test of one person managing multiple machines, there is still significant room for improvement in processing efficiency. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a material transfer mechanism that further improves processing efficiency.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A material transfer mechanism includes a frame, on which a material processing unit and a material placement platform are mounted. The material placement platform is provided with a placement area and a transfer area, and the material processing unit is located on one side of the transfer area.

[0008] It also includes a first material transfer unit and a second material transfer unit;

[0009] The first material transfer unit includes a first transfer frame, a first longitudinal drive, a first lifting plate, and a first lifting drive. The first transfer frame is mounted on the frame, the first lifting plate is located above the material placement platform, and the first lifting drive is used to drive the first lifting plate to move up and down. The first longitudinal drive is mounted on the first transfer frame and drives the first lifting drive to move back and forth between the placement area and the transfer area.

[0010] The second material transfer unit includes a second lateral drive, a second transfer frame, a second lifting plate, and a second lifting drive. The second lateral drive is used to drive the second transfer frame to move closer to or further away from the material processing unit. The second lifting plate is located above the transfer area. The second lifting drive is installed on the second transfer frame and is used to drive the second lifting plate to move up and down.

[0011] With the above technical solution, the material to be processed is first laid flat in the placement area. The first lifting drive unit drives the first lifting plate to move downward. The first lifting plate presses the material to be processed onto the material placement platform. The first longitudinal drive unit drives the first lifting drive unit to move. The first lifting plate transfers the material located in the placement area to the transfer area. During this process, the operator can lay the second piece of material to be processed flat in the placement area.

[0012] The material end in the transfer area is already on the material processing section. The second lifting component drives the second lifting plate to move downward. The second lifting plate presses down on the material in the transfer area. When the material processing section processes the material, the second transverse driving component drives the second transfer frame to move closer to the material processing section. At the same time, the second lifting plate can gradually and stably transfer the material into the material processing section for processing.

[0013] During the material transfer process described above, the operator only needs to continuously feed the material, and the first material transfer unit is only responsible for moving the material from the placement area to the transfer area. Subsequent feeding operations are handled by a separate second material transfer unit, and the first material transfer unit can quickly return to its original position in the placement area. This setup is more suitable for scenarios where one person manages multiple machines, significantly improving processing efficiency.

[0014] Preferably, the first transfer frame is slidably and positioned on the frame, and the sliding direction of the first transfer frame is parallel to the sliding direction of the second transfer frame.

[0015] With the above technical solution, the position of the first transfer frame can be pushed before processing begins, thereby controlling the distance between the first lifting plate and the material processing part, and adapting to the needs of material transfer of more sizes.

[0016] Preferably, the material placement platform has a positioning guard at the placement area.

[0017] With the above technical solution, the operator can lay the material flat in the placement area and simply place the side of the material against the positioning guard to complete the positioning requirements of the entire material. The placement accuracy is high and the operation is convenient.

[0018] Preferably, the positioning guard includes a transverse guard and a longitudinal guard, the transverse guard being parallel to the sliding direction of the second transfer frame, and the transverse guard and the longitudinal guard being perpendicular to each other.

[0019] With the above technical solution, the two adjacent edges of the material in the placement area can directly abut against the horizontal and vertical baffles, thereby completing the horizontal and vertical positioning of the material and further improving the positioning accuracy.

[0020] Preferably, an operating station area is provided on one side of the frame, and the operating station area is located on the side of the placement area away from the transfer area. An infrared detection device and a control unit are provided on the material placement platform.

[0021] An infrared detection device is installed between the placement area and the operating station area. The infrared detection device is used to detect whether the operator's hand is located between the placement area and the operating station area. The control unit is electrically connected to the infrared detection device and the first lifting drive component. When the infrared detection device detects that the operator's hand is located in the area between the placement area and the operating station area, the control unit controls the first lifting drive component to continuously lift and does not perform a downward operation.

[0022] With the above technical solution, when the operator's hand is in the detection area of ​​the infrared detection device, the control unit controls the first lifting drive to continuously lift without pressing down, so as to avoid the first lifting plate from accidentally crushing the operator's hand and improving operational safety.

[0023] Preferably, when the material is transferred to the transfer area by the first material transfer unit, one end of the material enters the material processing unit;

[0024] The second lifting plate of the second material transfer unit is used to press down on one end of the material located in the transfer area away from the material processing unit or to press down on the middle position of the material.

[0025] Through the above technical solution, since the sewing head's threading action on the fabric during the actual sewing process inevitably causes the fabric to wrinkle and deform to a certain extent, and the sewing machine also has a feed dog structure inside, although the large-area pressure plate can generate a relatively stable positioning and pressing force on the fabric, the feed dog inside the sewing machine, combined with the deformation of the fabric during the sewing process, can easily cause the entire piece of fabric to deviate if forcibly held. Therefore, the second lifting plate only needs to press down on the end of the material in the transfer area, and the entire material can be stably transferred into the material processing section without deviating, and has extremely high material transfer efficiency and stability.

[0026] In addition, the second lifting plate can be used to press down the middle of the material first. After part of the material is processed by the material processing department, the second lifting plate can be gradually transferred to the end of the material away from the material processing department. This also has extremely high material transfer efficiency and stability.

[0027] Preferably, the second lifting plate is a long strip plate, and the length direction of the second lifting plate is parallel to the sliding direction of the first lifting drive member.

[0028] With the above technical solution, the second lifting plate actually only exerts pressure on the end of the material away from the material processing part. Therefore, the shape of the second lifting plate is a long strip plate, and the length direction of the second lifting plate is parallel to the sliding direction of the first lifting drive component, which can generate a more stable pressing force on the material at this position.

[0029] Preferably, the second lifting plate includes a fixed plate and a movable plate. The fixed plate is fixedly connected to the driving end of the second lifting drive component, and the movable plate is located below the fixed plate. The movable plate and the fixed plate are slidably connected by a guide column, and an elastic component is also connected between the movable plate and the fixed plate.

[0030] With the above technical solution, when the second lifting plate presses down toward one side of the material placement platform, the material will be squeezed between the second lifting plate and the material placement platform. The movable plate and the fixed plate cooperate with each other through guide columns and elastic components, which can not only produce an elastic squeezing effect on the material, but also significantly improve the stability of the material pressing.

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 The specific embodiments of this utility model will be further described in detail to make the technical solution of this utility model easier to understand and master.

[0036] A material transfer mechanism includes a frame 1, on which a material processing unit 2 and a material placement platform 3 are mounted. The material processing unit 2 may be a sewing machine.

[0037] The material placement platform 3 has a placement area 4 and a transfer area 5, with the material processing unit 2 located on one side of the transfer area 5. Figure 2 For reference, the material processing unit 2 is located to the left of the transfer area 5.

[0038] A first material transfer unit 6 is installed on the frame 1. This first material transfer unit 6 includes a first transfer frame 61, a first longitudinal drive component 62, a first lifting plate 63, and a first lifting drive component 64. The first transfer frame 61 is installed on the frame 1, and the first lifting plate 63 is located above the material placement platform 3. The first lifting drive component 64 can be an electric cylinder or a pneumatic cylinder, and it drives the first lifting plate 63 to move up and down. The first longitudinal drive component 62 is installed on the first transfer frame 61, and it drives the first lifting drive component 64 to move back and forth between the placement area 4 and the transfer area 5, thereby allowing the first lifting plate 63 to move back and forth synchronously between the placement area 4 and the transfer area 5.

[0039] A second material transfer unit 7 is also installed on the frame 1. This second material transfer unit 7 includes a second transverse drive 71, a second transfer frame 72, a second lifting plate 73, and a second lifting drive 74. The second lifting plate 73 is located above the transfer area 5. The second lifting drive 74 can be an electric cylinder or a pneumatic cylinder. The second lifting drive 74 is installed on the second transfer frame 72 and is used to drive the second lifting plate 73 to move up and down. The second transverse drive 71 is installed on the frame 1 and is used to drive the second transfer frame 72 to move closer to or further away from the material processing section 2, thereby causing the second lifting plate 73 to move synchronously closer to or further away from the material processing section 2.

[0040] Both the first longitudinal drive component 62 and the second transverse drive component 71 can be selected from common drive forms such as a combination of motor, synchronous pulley, and synchronous belt, or a combination of motor and screw, or a common drive form of cylinder.

[0041] When the material is transferred to the transfer area 5 by the first material transfer unit 6, one end of the material enters the material processing unit 2. The second lifting plate 73 of the second material transfer unit 7 is used to press down the end of the material located in the transfer area 5 away from the material processing unit 2 or to press down the middle of the material. In this way, the second lifting plate 73 can both push the material to one side of the material processing unit 2 and give the material a certain degree of freedom of movement in the processing state, resulting in better material processing quality.

[0042] The second lifting plate 73 is a long strip plate, and its length direction is parallel to the sliding direction of the first lifting drive member 64. The second lifting plate 73 includes a fixed plate 731 and a movable plate 732. The fixed plate 731 is fixedly connected to the driving end of the second lifting drive member 74, and the movable plate 732 is located below the fixed plate 731. The movable plate 732 and the fixed plate 731 are slidably connected by a guide post 11. An elastic member 12, which is a spring, is also connected between the movable plate 732 and the fixed plate 731.

[0043] The first transfer frame 61 is slidably connected to the frame 1, and the sliding direction of the first transfer frame 61 is parallel to the sliding direction of the second transfer frame 72 to accommodate the transfer of materials of more sizes. Before the mechanism is activated, the first transfer frame 61 can first slide to a designated position, and then the first transfer frame is positioned at the designated sliding position.

[0044] The material placement platform 3 has a positioning guard 8 at the placement area 4. The positioning guard 8 includes a horizontal guard 81 and a vertical guard 82. The horizontal guard 81 is parallel to the sliding direction of the second transfer frame 72, and the horizontal guard 81 and the vertical guard 82 are arranged perpendicular to each other.

[0045] An operating station area 9 is provided on one side of the frame 1. The operating station area 9 is located on the side of the placement area 4 away from the transfer area 5. An infrared detection device 10 and a control unit are provided on the material placement platform 3. The infrared detection device 10 is installed between the placement area 4 and the operating station area 9. The infrared detection device 10 is used to detect whether the operator's hand is located between the placement area 4 and the operating station area 9. The control unit is electrically connected to the infrared detection device 10 and the first lifting drive 64. When the infrared detection device 10 detects that the operator's hand is located in the area between the placement area 4 and the operating station area 9, the control unit controls the first lifting drive 64 to continuously lift without performing a downward operation.

[0046] Both the first lifting drive component 64 and the second lifting drive component 74 can be selected from lifting cylinders.

[0047] The infrared detection device 10 described above includes a pair of infrared emitting tubes and infrared receiving tubes, which are arranged opposite each other on both sides of the working area to form a specific detection area.

[0048] When an object enters the detection zone, the infrared light emitted by the infrared emitter is blocked, and the intensity of the infrared signal received by the infrared receiver changes. The infrared receiver then transmits the received signal to the signal processing module of the control unit.

[0049] The signal processing module analyzes and processes the received signal to determine whether a hand has entered the detection zone. If the determination is that a hand has entered the detection zone, the signal processing module sends a control signal to the drive module.

[0050] Based on the received control signals, the drive module controls the first lifting drive component 64 to continuously rise without performing any downward operation. The first lifting drive component 64 operates synchronously under the control of the drive module, ensuring operational stability.

[0051] In practical applications, the detection range and sensitivity of the infrared detection device 10 and the control logic of the control unit can be adjusted according to specific needs to adapt to different working scenarios.

[0052] Taking fabric as the material to be processed as an example, the operation process of the above-mentioned material transfer mechanism is as follows: Based on the overall size of the batch of fabric, adjust the position of the first transfer frame 61, and then position the first transfer frame 61 in that position. The operator stands in the operating station area 9 and lays the first piece of fabric flat in the placement area 4, accurately placing it in the placement area 4 using the transverse baffle 81 and longitudinal baffle 82 as references. The first lifting drive component 64 drives the first lifting plate 63 to move downwards, pressing the material to be processed onto the material placement platform 3. The first longitudinal drive component 62 drives the first lifting drive component 64 to move, and the first lifting plate 63 transfers the material located in the placement area 4 to the transfer area 5. During this process, the operator can then lay the second piece of material to be processed flat in the placement area 4. One end of the material in the transfer area 5 is already on the material processing section 2. The second lifting drive 74 drives the second lifting plate 73 to move downward. The second lifting plate 73 presses down on the end of the material in the transfer area 5. When the material processing section 2 processes the material, the second transverse drive 71 drives the second transfer frame 72 to move closer to the material processing section 2. At the same time, the second lifting plate 73 can gradually and stably transfer the material into the material processing section 2 for processing.

[0053] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
