Embodiment Construction

[0033] The sewing device 1 of the present invention will be described. In the following description, left and right, front and rear, and up and down indicated by arrows in the drawings are used. Such as Figure 1 to Figure 5 As shown, the sewing device 1 is a gate type, and has a base part 2, a pillar part 3, a pillar part 4, a beam part 5, a needle bar mechanism 6, an upper and lower mechanism 66, a shuttle mechanism 7, a holding mechanism 8, a carrying mechanism 9, The conveying mechanism 10 and the operation part 11.

[0034] The base unit 2 has a base 21 , a holding plate 22 , an opening 24 , an opening 25 , a corrugation 26 , a corrugation 27 , a frame 28 , and a lower rail 29 . The base 21 has a substantially rectangular parallelepiped shape. The holding plate 22 constitutes the upper surface of the base 21 and extends parallel to the horizontal plane. The holding plate 22 has an opening 23 extending in the left-right direction. The opening portion 24 extends in the f...

Abstract

The invention relates to a sewing device. The sewing device is provided with a needle bar mechanism, a shuttle mechanism, a moving mechanism and an up-down mechanism. The moving mechanism moves the shuttle mechanism and the needle bar mechanism in a direction parallel to the horizontal direction with respect to the object to be sewn. The up-down mechanism enables the needle bar mechanism to move to a lower position and an upper position, the lower position is an up-and-down direction position where the needle bar mechanism is located when a sewing object is sewn, and the upper position is closer to the upper portion than the lower position. The sewing device sets the position of the needle bar mechanism in the vertical direction to be either the lower position or the upper position duringidle conveying, and idle conveying means that the moving mechanism is driven under the condition that the needle bar mechanism does not enable the needle bar to move up and down, so that the needle bar mechanism and the shuttle mechanism move in the horizontal direction relative to the sewing object.

Description

technical field [0001] The invention relates to a sewing device. Background technique [0002] The sewing device disclosed in Japanese Patent Publication No. 116975 of 2000 has a needle bar mechanism, a shuttle mechanism, a moving mechanism and an up and down mechanism. The needle bar mechanism has a needle bar to which a needle can be mounted at the lower end, and the needle bar can be moved up and down. The shuttle mechanism is located below the needle bar mechanism and has a shuttle. The moving mechanism moves the shuttle mechanism and the needle bar mechanism along a first direction and a second direction parallel to the horizontal direction. The up and down mechanism can move the needle bar mechanism to a lower position where the needle bar mechanism is located when sewing an object to be sewn, and an upper position that is higher than the lower position. [0003] This sewing device repeats the following process: After one sewing is finished, the up and down position...
