Description

Automated shoe last structure

This creation is about an automated shoe last structure, especially a shoe last structure that provides a seamless integration with automated processes, making it the primary author of the application of consistent precision machining procedures.

Press, the shoe last is mainly a shoe mold for determining the size of the shoe; in other words, the shoe last is not only the mother of the shoe, but also the molding die of the shoe. Therefore, the design of the shoe last must be based on the user's foot shape and size. The foundation can be used to make a matching shoe that meets the actual size requirements of the foot.

Generally, the shoe last is divided into three types: wood, plastic and metal. Traditional shoe lasts are made of hardwood trees with hard texture, high density and fine texture. With the development of technology and the rise of personalized consumption awareness, it has evolved into the demand and supply of a large number of footwear products. The method of producing wooden shoe lasts by manual or mechanical processing is bound to fail to meet the production requirements of today's footwear products. Because of this, wooden shoe lasts have gradually been replaced by plastic shoe lasts made of HDPE high-density polyethylene, which has become the main type of shoe lasts for the modern footwear industry; plastic shoe lasts are mainly molded into high-density polyethylene into shoe lasts. The shoe last is then milled to the desired shoe curve using a special shoe last.

The processing procedure of the special shoe lasting machine is to set the shoe last blank in the machine table, and respectively fix and clamp the two ends of the shoe last blank, so that the two ends of the positioning form an axis, and the shoe last blank can be rotated, and then The processing tool is introduced from the side, and the corresponding shoe blank is processed by coarse, fine and fine milling to complete the required shoe last shape, but the ends of the shoe last after processing [ie, the toe and the back of the shoe) The part is left in the fixed position of the blank material, so it is necessary to manually trim the raw material of the raw edge. It can be seen that in the traditional shoe last processing process, the steps are complicated and cannot be automated, resulting in process time and the like. Aung, it has become a technical issue that the technical field of the related art is eager to solve and challenge.

However, automation has gradually become a development trend in various industries. In the past, the traditional shoe-making industry, which is dominated by the handicrafts, has now developed automation machinery that can automatically produce shoes, such as through 3D visual path generation, without standardization. The product can also be produced, and it can be more efficient in the customization of the shoes. Based on the trend that future footwear will be oriented towards a small number of diverse productions, there is a need for an automated robotic control shoemaking production facility that uses automated robotic arms to grab shoe lasts for multi-process sites; and as such, in order to provide automated robotic arms To grab the shoe last for shoemaking, the shoe last needs to be installed with a clamp for the mechanical arm; and the clamp needs to be locked and positioned on the end of the shoe last after the special shoe last machining, The end face is drilled with a keyhole, such as Taiwan Patent Publication No. M526300 "Automatic Multi-purpose Shoe Last Fixture", and the clip seat is fixed by the keyhole; however, the technique of drilling the keyhole needs to be very precise, if some The deviation selection will result in different clamping positions on each shoe last. When the clamping seat is clamped by the mechanical arm, it enters the automatic processing process, and the machining process mainly takes the position of the clamping seat as the reference, so that the shoe last and processing There is a corresponding relationship between the fixture and the tool in the three-dimensional space. If there is a slight deviation in the seat of each shoe, the positioning of each shoe is relatively different from that of the processing fixture and tool. The inaccurate displacement of the positioning is missing, which has serious consequences for the high rate of non-performing.

Today, the creator has been adhering to the rich experience in designing and developing the actual industry for many years, and has provided an automatic shoe last structure to achieve better practical value.

When actually making an automatic shoe last, it can be achieved by the following production methods, with a brief description of the production steps:

Referring to the three to six figures, first, through the embryo substrate step, an embryo substrate (10) is first obtained, and the embryo substrate (10) is made of a high density polymer, such as An embryo substrate (10) prepared by polyethylene, and the appearance of the embryo substrate (10) has a rectangular shape or a slightly shoe-shaped block, and the embryo body is injected. The substrate (10) is formed with a set of end faces (11) and at least one side face (12) of the adjacent assembled end faces; and then drilled on the assembled end faces (11) of the blank body substrate (10) The locking hole (13) is provided, and the number of the locking hole (13) is evaluated according to the size and length shape of the locking clamping seat (2), and basically needs at least two locking holes (13), and then one side Corresponding to the locking hole (13), a positioning hole (14) intersecting with each other is drilled, and a locking fastener (4) is respectively embedded in the positioning hole (14) to allow the locking component (4) Lying at the intersection of the positioning hole (14) and the locking hole (13), the locking The piece (4) has an internal thread (41) that can be locked with the screw (5).

Next, a positioning clamping step is performed to prepare a clamping seat (2) having a clamping path (21), the clamping channel (21) being designed to be changed in response to the collet (31) of the automated processing device (3), It is not limited to the specific shape of the clamping channel (21), and further, the clamping seat (2) is provided with a through hole (22) corresponding to the locking hole (13), and the through hole (22) is provided for the screw (5).

However, in the automated processing process, whether the body is processed or the subsequent shoe processing process, the body substrate (10) is rotated by the chuck (31) and the movement path is 360 degrees at any angle. The shape of the shoe is changed, so that the force applied to the body substrate (10) is more than the vertical direction of the holder (2), and the lateral force caused by the rotation; therefore, In the invention, the embryo body substrate (10) is reciprocated by longitudinally punching a keyhole (13) and laterally driving into the positioning hole (14), and is locked in a lateral direction by a screw (5) longitudinally penetrating the keyhole (13). The locking member (4) in the positioning hole (14) generates a straight locking force, and the pulling force extended by the straight locking force urges the locking member (4) against the edge of the positioning hole (14) to reach the clamp. The seat (2) is fixed in both directions vertically and horizontally to conform to changes in the path of motion.

Subsequently, the embryo body substrate (10) on which the holder (2) is mounted is passed through a chuck (31) of an automated processing device (3) corresponding to the clip by (c) a gripping processing step.

However, in the positioning process of the embryo substrate (10), the locking member (4) is embedded in the lateral positioning hole (14), and is mainly used for locking the screw (5) longitudinally penetrating the locking hole (13). When the screw (5) is locked into the lateral locking member (4), a straight locking force is generated, and the pulling force during the locking process presses the locking member (4) against the edge of the positioning hole (14), so the locking member ( 4) The end face corresponding to the screw (5) is required to bear the force. In order to consider the force problem, the locking member (4) may be a circular body as shown in the figure, or a square type capable of withstanding a large force. Body, hexagonal body, etc., or any other type of body; of course, the hole shape of the positioning hole (14) varies with the fastener (4).

The shoe last body (1) is produced by the above method, and the shoe last body (1) is produced by using the holder (2) as a processing reference for each of the body substrate (10). The shoe last body (1) is shaped and dimensioned without angle and curvature error; when finished, each shoe last can enter the automated process via (d) automated production steps such as plastic shoe shape, glue, and whole ...When machining, the clamp (2) is unchanged, the reference is unchanged, and the size, angle, and curvature of the shoe last are the same, so there is no defective product.
