Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a label pickup device for efficiently supplying a label made of cloth or the like to be sewn to clothes to a sewing machine in a sewing operation using a sewing machine, and particularly to a label cut and laminated in a strip shape The present invention relates to a pickup device capable of picking up one by one and simultaneously forming a label in half.

[0002]

[Prior art]

 One of the sewing processes for ready-made clothes is to sew a cloth label indicating the washing method and manufacturer.

For this purpose, labels must be supplied to the sewing machine one by one, but as a conventional device for efficiently supplying the labels to the sewing machine, there is a chuck type pick-up device. This pickup device will be described with reference to FIG.

This pickup device has a pair of metal clamp parts 2 and 2 which can be raised and lowered and opened and closed by a driving means (not shown). Then, both clamp portions 2 of the pick-up device are pressed in an open state to the vicinity of the central portion of the label 1 which is cut and laminated in advance in a strip shape, and both clamp portions 2 of the driving means are pressed. When it is closed by driving, the cloth of the label 1 interposed between the front end portions 2a of the clamp portions 2 that come into contact with the label 1 and 2a is rubbed against the central portion. Then, by raising both clamp parts 2 by the driving means, when the closed clamp tip part 2a is separated from the label 1, as shown in FIG. By sandwiching the play part of the label 1, one label 1 can be picked up.

[0005]

[Problems to be solved by the device]

 However, in the conventional pickup device described above, since the clamp portion 2 is required to have durability, it is made of metal as described above, and therefore, the clamp portion 2 is sandwiched between both tip portions 2a of both clamp portions 2. The label 1 part was damaged. Further, in the case of the label 1 made of a nylon-based material, the label 1 is slippery due to its material, and the frictional resistance of the metal clamp portion 2 is too small to hold the label 1 in some cases. Even if 1 was able to be sandwiched, stability was poor when picking up label 1. Further, since the conventional pickup device is not designed to reliably form the label 1 into two folds, in order to sew the label 1 in two, the label 1 is folded in two. Another mechanism was needed.

The present invention provides a label pick-up device that overcomes the problems of the conventional ones and can stably fold a label one by one and feed it to a sewing machine. With the goal.

[0007]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, a pickup device of the present invention is arranged above a plurality of stacked labels, and is a label pick-up device that picks up the labels one by one, and is arranged so that it can be moved up and down. When the air distributor is connected to the suction pipe, the other end is opened and a suction pipe is formed in the lower part that communicates with the internal space. It is characterized by having a member and.

[0008]

[Action]

 According to the pickup device of the present invention, the label is sucked into the inner space through the slit by using the negative pressure of the air in the inner space of the suction pipe, so that the label is not damaged and is folded in two. Labels can be reliably picked up one by one while molding into a state.

EXAMPLES The present invention will be described below with reference to examples shown in the drawings.

An air cylinder 4a extending in the vertical direction is arranged above the central portion (position L / 2) in the longitudinal direction (overall length L) of the labels 3 that are cut and laminated in a rectangle of a predetermined size. The piston rod 5a of the air cylinder 4a hangs downward from the lower end of the air cylinder 4a. The piston rod 5a is moved up and down by switching the air supply direction to the air cylinder 4a.

An adsorption pipe 6 is supported at the lower end which is the tip of the piston rod 5a. As shown in detail in FIGS. 4 and 5, the suction pipe 6 is formed in a linear shape extending in the horizontal direction. A slit 8 communicating with the inner space 7 is formed in the lower portion of the adsorption pipe 6 over the entire area of the adsorption pipe 6 in the longitudinal direction, and the adsorption pipe 6 has a substantially U-shaped vertical cross section. ing. The entire length of the suction pipe 6 is formed to be longer than the width of the label 3.

As shown in detail in FIG. 6, an air supply device 9 such as a blower, which is an example of an air distributor, is provided outside the upper part of the one end of the adsorption pipe 6 in the longitudinal direction. The ejection nozzle 10 faces. The jet nozzle 10 can move up and down together with the suction pipe 6, and the air jetted from the jet nozzle 10 of the air supply machine 9 flows in the upper portion of the suction pipe 6 along its longitudinal direction. It will be.

By the way, as is clear from FIG. 6, it is desirable that the edge of the label 3 is located outside the end of the suction pipe 6 facing the ejection nozzle 10 facing the inside. . This is because the jet of air from the jet nozzle 10 causes a negative pressure in the lower portion of the suction pipe 6, and the negative pressure causes the label 3 to be sucked into the suction pipe 6, which causes the negative pressure. Since the label 3 is somewhat driven in the direction of air flow in the suction pipe 6 during suction, it is better to position the label 3 at a position displaced in the longitudinal direction of the suction pipe 6. The reason is that the suction pipe 6 and the label 3 are completely aligned at the suction position and the suction can be surely performed.

For the inner peripheral surface of the suction pipe 6, it is desirable to use metal or the like having a low frictional resistance in order to enhance the moldability of the label 3 in the two-fold shape, and the material having a large frictional resistance is the inner peripheral surface. Need to be polished. Looking only at the holding force of the label 3, the holding force of the label 3 can be increased if the inner peripheral surface of the suction pipe 6 has a large friction resistance. However, if the inner peripheral surface of the suction pipe 6 has a large friction resistance, the surface roughness of the inner peripheral surface becomes rough, so that not only the formability of the label 3 is impaired but also the label 3 may be damaged. On the other hand, the increase in the holding force of the label 3 can be compensated for by increasing the air pressure, and for normal removal of the label 3, a pressure of 1 to 1.5 kg / cm ² is sufficient. Become. Therefore, as described above, it is desirable to consider the inner peripheral surface of the adsorption pipe 6 so as to enhance the formability.

Returning to FIG. 1, air cylinders 4b and 4c are disposed above both ends in the longitudinal direction of the label 3, and the piston rods 5b and 5c of the air cylinders 4b and 4c are air cylinders. It hangs downward from the lower ends of 4b and 4c. The piston rods 5b and 5c are moved up and down by switching the air supply direction to the air cylinders 4b and 4c.

The lower ends of the piston rods 5b, 5c are made of a material having a large frictional resistance such as rubber, and the labels 3, 3, ... A pressing member 11 that prevents the label 3a from being picked up is provided.

Next, the operation of this embodiment having the above-mentioned configuration will be described.

FIG. 1 is a side view showing a standby state of the label pickup device of this embodiment. From this state, first, as shown in FIG. 2, the piston rod 5a of the air cylinder 4a is moved down to just above the laminated label 3. Then, the air supply device 9 is driven to eject air from the ejection nozzle 10 at high speed into the adsorption pipe 6. Then, a negative pressure is generated in the adsorption pipe 6. Then, the negative pressure causes the central portion in the longitudinal direction of the single label 3a stacked on the top to be floatingly adsorbed in the width direction. In this state, the label 3a is still in a position so as to close the slit 8 of the suction pipe 6.

Next, as indicated by arrows in FIG. 3, the suction pipe 6 is raised by raising the piston rod 5a of the air cylinder 4a, and the piston rods 5b, 5c of the air cylinders 4b, 4c are lowered. As a result, the pressing members 11 and 11 located at both ends of the label 3 are lowered, and both ends of the laminated label 3 located below the attracted label 3a whose both ends are moved inwardly are pressed. Hold in position. In this state, the air cylinder 4a is further driven to raise the piston rod 5a together with the label 3a, and air ejection from the ejection nozzle 10 is continued. By doing so, as shown in FIGS. 4 (A) and 4 (B) in sequence, the central portion of the label 3a is pulled deep into the inverted U-shaped suction pipe 6 by negative pressure, and the cross section of the suction pipe 6 is shown. It will be molded into a shape (U shape).

In order to take out the label 3a, which is formed into a U-shape in the central portion and is folded in half, from the suction pipe 6, as shown in FIG. 5, both ends of the label 3a held by the suction pipe 6 are held. The portion (indicated by diagonal lines) is clamped by another clamp (not shown) to temporarily stop the air ejection from the ejection nozzle 10 of the air supply device 9 into the adsorption pipe 6, and then to the end where the ejection nozzle 10 is located. By pulling the label 3a toward the end of the suction pipe 6 on the opposite side, the label 3a can be pulled out from the suction pipe 6.

As described above, according to the label pickup device of the present embodiment, air is jetted from the jet nozzle 10 of the air supply device 9 into the suction pipe 6 so that the suction pipe 6 has a negative pressure and is stacked. The uppermost label 3a among the attached labels 3 can be folded in two and reliably picked up.

It should be noted that the present invention is not limited to the above-mentioned embodiment, but can be modified as necessary. For example, as the air distributor, in addition to the air supplier as shown in the embodiment, a vacuum pump for sucking air may be used.

[0023]

[Effect of device]

 As described above, according to the label pickup device of the present invention, since the label is sucked by using the negative pressure of air, it is possible to reliably pick up the label without damaging it. In addition, the shape of the suction pipe has a slit that communicates with the internal space at the bottom, so that the label is formed into a folded state at the same time as it is sucked, thus shortening the work process. Not only that, the mechanism for folding the label in half can be eliminated.
