Description
Technical Field
[0001] The utility model belongs to the technical field of shoemaking, and particularly relates to an assembly line pushing shoe last device. Background Art
[0002] In existing shoemaking factories, the insole nailing process is located on one side of the assembly line, and the next process, the toe-tiing process, is located on the same side of the assembly line as the insole nailing process. After the insole nailing process is completed, the shoe last is directly transported to the toe-tiing process through the assembly line. However, in actual application, the speed of the insole nailing process is fast, and the speed of the toe-tiing process is slow. Due to the different speeds of the insole nailing process and the toe-tiing process, in order to make the insole nailing process and the toe-tiing process work well together, the speed of the insole nailing process can only be slowed down, which greatly affects work efficiency.
[0003] The pointing process is relative to the second pointing process on the opposite side of the assembly line. Since the assembly line is wider, with a width of 1.5m, the workers in the pointing process have to work in a sitting position. It is inconvenient for the workers in the second pointing process to take and put the shoe lasts delivered from the assembly line. Bending over and stretching the arms to take the shoe lasts for a long time is not conducive to lean production and has a greater impact on the workers' cervical, shoulder and lumbar vertebrae.
[0004] To this end, the technical problem to be solved by the present invention is: in order to make the insole nailing process and the toe-stretching process better coordinated, the existing technology can only slow down the speed of the insole nailing process, resulting in low shoemaking efficiency; the toe-stretching process is relative to the second toe-stretching process on the opposite side of the assembly line, and the workers have to bend over and stretch their arms for a long time to hold the shoe last, which is not conducive to lean production.

A transmission device, a control device and a detection device are fixed on the operating table; the transmission device and the detection device are electrically connected to the control device; the transmission device includes a cylinder, and the output end of the cylinder is fixedly connected to the L-shaped shoe last back support.
[0008] The cylinder is a rodless cylinder, and the operating table includes an upper plate.

[0009] The upper plane of the cylinder output end is flush with the upper plane of the upper plate of the operating table, and the upper plane of the cylinder output end is fixed to the L-shaped shoe last rear support.

[0023] Long groove 7, shoe last 8, insole nailing process 9, toe-tightening process 10, second toe-tightening process 11 DETAILED DESCRIPTION
[0024] The following is a clear and complete description of the technical solutions in the embodiments of the present invention, in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the implementation of the present invention, not all of it. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0025] In actual shoemaking operations, when switching production, the equipment of the entire production line needs to be re-set up and the processes need to be rearranged. There is an adjustment time. The insole nailing process 9 is placed at the first step of the sole making process, that is, the front end of the assembly line 1, and a last pushing device is set at the insole nailing process 9. The range of the input air pressure of the cylinder 31 is adjusted to ensure that the shoe last 8 can be transferred to the opposite side area of the assembly line 1.
[0026] In the present invention, the head end of the long slot 7 refers to the end of the long slot 7 close to the assembly line 1; the tail end of the long slot 7 refers to the end of the long slot 7 away from the assembly line 1.
[0027] like Figure 1-3 As shown, the utility model provides an assembly line to push the shoe last device, which is arranged at the insole nailing process 9. The insole nailing process 9 is adjacent to the assembly line 1. An operating table 2 is provided on one side of the assembly line 1. A long slot 7 is provided on the operating table 2. A transmission device, a control device 4 and a detection device 5 are fixed on the operating table 2; the transmission device and the detection device 5 are electrically connected to the control device 4; the transmission device includes a cylinder 31, and the output end of the cylinder 31 is fixedly connected to the L-shaped shoe last back support 32.
[0028] The utility model provides a last-pushing device for an assembly line, so that a part of the shoe lasts processed in the insole nailing process flows along the assembly line to the toe-tightening process for processing, and the other part of the shoe lasts falls into the opposite area of the assembly line by pushing the last-pushing device, and flows along the assembly line to the second toe-tightening process for processing. There is no need to slow down the speed of the insole nailing process, which greatly improves work efficiency. Moreover, the shoe lasts transported to the second toe-tightening process are all shoe lasts processed in the insole nailing process, which will not cause confusion. At the same time, it also avoids the workers from bending over and stretching their arms to take the shoe lasts for a long time, which is conducive to lean production.
[0029] like Figure 2 As shown, the cylinder 31 is a rodless cylinder, the operating table 2 includes an upper plate, the cylinder 31 is fixed to the bottom of the upper plate of the operating table 2, and is located below the long slot 7, so that the L-shaped shoe last back support 32 slidingly connected to the cylinder 31 can reciprocate above the long slot 7.
[0030] The upper plane of the output end of the cylinder 31 is flush with the upper plane of the upper plate of the operating table 2, and the upper plane of the output end of the cylinder 31 fixes the L-shaped shoe last rear support 32, so that the L-shaped shoe last rear support 32 can reciprocate along the long groove 7. The L-shaped shoe last rear support 32 is used to hold the shoe last 8 processed in the insole nailing process 9, so that the shoe last 8 can move synchronously with the L-shaped shoe last rear support 32.
[0031] When the cylinder 31 drives the L-shaped shoe last rear support 32 to move above the long slot 7 in the direction close to the assembly line 1, the L-shaped shoe last rear support 32 drives the shoe last 8 to move synchronously. When the L-shaped shoe last rear support 32 moves to the head end of the long slot 7, it stops moving, and the shoe last 8 falls into the area on the opposite side of the assembly line 1 under the action of inertia;
[0032] When the cylinder 31 drives the L-shaped shoe last rear support 32 to move above the long slot 7 in the direction away from the assembly line 1, the L-shaped shoe last rear support 32 stops moving when it moves to the tail end of the long slot 7, pushing the shoe last device to reset and wait for the next instruction.
[0033] like Figure 3 As shown, the L-shaped shoe last back support 32 and the long slot 7 are provided with an angle, and the angle range is 10-45 degrees.
[0034] In the present invention, the two sides of the L-shaped shoe last rear support 32 are perpendicular to each other. If the L-shaped shoe last rear support 32 is set parallel to the long groove 7, that is, one side of the L-shaped shoe last rear support 32 is parallel to the long groove 7, and the other side is perpendicular to the long groove 7, then the point of action for pushing the shoe last 8 is the side perpendicular to the long groove 7. Since the shoe last 8 is not a regular shape, if the shoe last 8 is pushed in parallel, the shoe last 8 will have a certain offset under the reaction force. Setting the L-shaped shoe last rear support 32 at an angle to the long groove 7 is equivalent to forming a limit on both sides. The points of action for pushing the shoe last 8 are the two sides of the L-shaped shoe last rear support 32. The inclined setting makes it more convenient to push the shoe last 8 to move, and is not prone to deflection.
[0035] The air cylinder 31 is connected to a pressure gauge, and the range of the air pressure input to the air cylinder 31 is adjusted by the pressure gauge to adjust the thrust applied to the shoe last 8 .
[0036] The pressure gauge adjusts the range of the input air pressure of the cylinder 31 to be 4-5kg, and the distance that the shoe last 8 slides on the assembly line 1 is 0.5-1 of the width of the assembly line 1, that is, under the action of thrust, the distance that the shoe last 8 slides on the assembly line 1 exceeds half of the width of the assembly line 1, that is, the shoe last 8 can slide to the other half of the area on the assembly line 1 away from the operating table 2. Within this area, it belongs to the area on the opposite side of the assembly line 1, so as to ensure that the staff of the second toe-pointing process 11 can pick up the shoe last 8 conveyed on the assembly line 1 without having to lean over or bend down.
[0037] The assembly line 1 is preferably made of a material with a smooth surface so as not to affect the sliding of the shoe last 8 on the assembly line 1. Generally, the smallest size of the shoe last 8 used is 235 and the largest size is 290. The weight of a single shoe last 8 is more than one kilogram. For example, the weight of a single shoe last 8 of the most commonly used type of intermediate size 255 is 1114 grams.
[0038] like Figure 3 and Figure 4 As shown, the control device 4 is fixed to the bottom of the upper plate of the operating table 2 at the tail end of the long slot 7, located at the end of the cylinder 31. The control device 4 is used to receive instructions, transmit signals with the detection device 5, and control the actions of the cylinder 31 and the lifting cylinder.
[0039] like Figure 2-4 As shown, the detection device 5 is arranged at the edge of the operating table 2 near one side of the assembly line 1, and the detection range of the detection device 5 is as follows Figure 4 As shown, preferably, it is possible to detect the upstream position before the extension line of the movement direction of the cylinder 31 passes through the assembly line 1. The detection device 5 can use a sensor, an infrared signal detector or other detection components, as long as it can achieve the same function, for detecting whether there is an obstacle in the movement trajectory area of the shoe last on the assembly line 1, and transmitting the detected signal to the control device 4. The obstacle is generally a semi-finished product on the assembly line 1.
[0040] If the detection device 5 detects that there are no obstacles in the movement trajectory of the shoe last on the assembly line 1, it transmits a signal indicating that there are no obstacles to the control device 4. The control device 4 controls the transmission device to operate to transfer the shoe last 8 to the opposite side of the assembly line 1. After the shoe last 8 is transferred, the transmission device resets and waits for the next instruction.
[0041] If the detection device 5 detects that there is an obstacle in the movement track area of the shoe last on the assembly line 1, a signal indicating the presence of the obstacle is transmitted to the control device 4, and the control device 4 controls the transmission device to not move.
[0042] The operating table 2 is arranged at the insole nailing process 9 and is located on one side of the assembly line 1. After the shoe last 8 is processed in the insole nailing process 9, the shoe last 8 can be transferred to the opposite side area of the assembly line 1 using the shoe last pushing device of the present invention. No manual operation is required, and the system is convenient and reliable. The cylinder 31 is used as the driving device, and the driving device is simple.
[0043] The operating platform 2 can be raised and lowered. A lifting cylinder (not shown in the accompanying drawings) is connected to the operating platform 2. The lifting cylinder is electrically connected to the control device 4. The control device 4 controls the movement of the lifting cylinder to control the operating platform 2 to be raised and lowered to different heights. It is suitable for production lines 1 of different heights and has a wide range of applications.
[0044] The utility model can also set a guard plate at the side opposite to the assembly line 1 corresponding to the head end of the long groove 7 to play a blocking role.
[0045] The specific working process of this utility model is:
[0046] After the shoe lasts 8 are processed in the insole nailing process 9, part of the shoe lasts 8 are transferred along the assembly line 1 to the toe-tightening process 10 for processing, and the other part of the shoe lasts 8 are pushed to the opposite side of the assembly line 1 by the last-pushing device and transferred along the assembly line 1 to the second toe-tightening process 11 for processing;
[0047] After placing the shoe last 8 on the L-shaped shoe last back support 32, the staff at the insole nailing process 9 sends an instruction to the control device 4, and the control device 4 transmits a signal to the detection device 5. The detection device 5 detects whether there are obstacles in the movement trajectory area of the shoe last on the assembly line 1 and transmits the detected signal to the control device 4. The control device 4 controls whether the transmission device is activated based on the detected signal.
[0048] Specifically:
[0049] When the detection device 5 detects that there is no obstacle in the shoe last movement trajectory area on the assembly line 1, a signal indicating that there is no obstacle is transmitted to the control device 4. The control device 4 controls the transmission device to operate, and the cylinder 31 drives the L-shaped shoe last rear support 32 to move above the long slot 7 in a direction close to the assembly line 1. The L-shaped shoe last rear support 32 drives the shoe last 8 to move synchronously. When the L-shaped shoe last rear support 32 moves to the head end of the long slot 7, it stops moving. The shoe last 8 falls into the area on the opposite side of the assembly line 1 under the action of inertia. After the pushing is completed, the cylinder 31 drives the L-shaped shoe last rear support 32 to move above the long slot 7 in a direction away from the assembly line 1. When the L-shaped shoe last rear support 32 moves to the tail end of the long slot 7, it stops moving, pushing the shoe last device to reset and wait for the next instruction.
[0050] When the detection device 5 detects that there is an obstacle in the movement track area of the shoe last on the assembly line 1, a signal indicating the presence of the obstacle is transmitted to the control device 4, and the control device 4 controls the transmission device to not move.
[0051] In the present invention, the detection device 5 transmits a signal to the control device 4, and the control device 4 controls the operation of the transmission device according to the received signal. This is the prior art.
[0052] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
