Description

[Detailed description of the invention] Industrial field of application The present invention is a type of insole material, commonly known as "drop", which is housed in gift boxes for whiskey, ham, etc. and is used to give the product a high-class image. This is related to an automatic production device called (Guess).

Shitadare is generally made by folding cloth in a deep and glossy color such as red or blue to give it some slack, then pasting it around a mount formed by punching paperboard or cardboard according to the shape of the product inside. As shown in Figure 11, the mount is placed in a gift box, and the product inside is positioned and placed in the punched hole in the mount, so that the slack cloth fits into the punched hole in the mount along with the product inside. This product is made to stand out against the backdrop of the cloth, giving it a high-class image.

Problems that Hatsua is trying to solve Conventionally, the production of the above-mentioned droops has been dependent on manual labor, as the work of folding the fabric vertically and horizontally to create slack and attaching it to the backing paper cannot be automated. It is extremely inefficient (approximately 50 pieces per person per day), and packaging costs are increased because gift-giving is concentrated during gift-giving periods such as mid-year gifts and year-end gifts, so automation of this process is desired.

In response to the above request, a device has been provided in which the cloth is folded in only one direction (vertical direction) and attached to a mount (Nihon Shiki Shimbun, published February 21, 1988, p. 7). Since this device is simply attached to a mount with folds in only one direction, it does not have the texture of a handmade product with slack in the vertical and horizontal directions, and when the product is stored, the folds are In the opposite direction, there was a problem that the fabric tended to stretch, and the contents could not be properly stored in the punched holes of the mount.

Means for Solving the Problems In order to achieve the above-mentioned object, the automatic manufacturing device for packaging hangers of the present invention includes a cloth holding table having a plurality of cloth clamping members between a pair of rotary plates, and A cloth supply mechanism that supplies the cloth to the holding base, a base supply mechanism that applies glue around the base paper and supplies the base paper to the cloth holding base, and a pressure bonding mechanism that presses the cloth and the base paper, The pair of rotary plates of the holding base are movable toward and away from each other in the axial direction, and are driven to rotate integrally, while the cloth clamp member is moved along an arcuate surface between the two rotary plates arranged in a substantially rectangular shape. Two arcuate guide rods and two linear guide rods parallel to the axis of rotation are interposed with compression springs or belt-like or linear strings, and multiple cloth clamp members can be approached simultaneously. This allows for remote movement.

In the above solution, first, the cloth supplied from the cloth supply mechanism is sucked while the rectangular area formed by the cloth clamp member is expanding. As the pair of rotating plates rotate, the rectangular area formed by the cloth clamping member is reduced. Then, pleats are formed in the cloth that is being sucked, and the cloth becomes
Glue is applied to the mount paper supplied from the mount supply mechanism. At this time, each cloth clamp member releases the suction of the cloth. The pair of rotary plates further rotates, the rectangular area formed by the cloth clamping member expands, and the above operation is repeated.

) enters between the fork-shaped guide members (59) while rotating, so the movable rotary plate (34) smoothly moves toward the rotary guide plate (33). As the movable rotary plate (34) approaches, the cloth clamp member (52) is inserted into the arcuate guide rod (51) that approaches the movable rotary plate (34).
comes into contact with the movable rotating plate (34) and rotates the rotating guide plate (33).
) side. First fixed guide Rondo (50a
) and the movable guide rod (50b) at the end have a cloth clamp member (5) at the intersection of the arcuate guide rod (51).
2), so these cloth clamp members (5)
2) is the rotary guide plate (33) from the movable rotary plate (34) side.
) side, and the interval between the cloth clamp members (52) becomes narrower.

Therefore, as shown in FIG. 10, the cloth clamping member (52) moves to the lower side of the cloth holding table (A') with its rectangular area reduced and folds formed in the cloth. There, the cloth is adhered to the backing paper by a pressure roll (20).

The leading fixed guide iron (50a) is connected to the pressure roll (20
), the first fixed guide rod (50a)
The suction hole (36a) at the top of the first rotating shaft (36) to which the hose (54b) leading out from the cloth clamp member (52) inserted is connected is located at the 10 o'clock position, and the fixed shaft at this position (35) has no stepped portion, and this cloth clamp member (
The suction from the air intake hole (52a) of 52) is stopped, and the backing paper is attached to the cloth. Thereafter, as the cloth clamp member (52) rotates, suction from the suction hole (52a) of the cloth clamp member (52) inserted through the moving guide rod (50b) is also stopped, and the suction of the cloth is released. do.

After the cloth clamp member (52) inserted through the trailing moving guide rod (50b') passes the pressure roll (20), the area of the cloth clamp member (52) which has been reduced is expanded. That is, the rotary cylinder (47) is rotated in a direction opposite to that of the fixed rotary plate (31) and the movable rotary plate (34), and the rotating guide plate (33) and the movable rotary plate (34) are rotated.
Fixed rotating plate (31) and fixed rotating ring (32)
relatively slower than the rotation speed of. Then, the movable guide rod (50b') at the end rotates relatively later than the fixed guide rod (50a) at the front.
The distance between both guide rods (50b') (50a) becomes wider. At the same time, the second air supply hole (3
5e) to the second port (44c) of the inner rotating base cylinder (44).
). Then, the piston rear chamber (43c) expands, and the inner rotating base cylinder (44) retreats toward the third rotating shaft (38). The inner rotating base cylinder (44) is a movable rotating plate (34)
is fixed, the movable rotary plate (34) moves closer to the fixed rotary ring (32) as the inner rotary base cylinder (44) retreats. The relatively slow rotation of the movable guide rod (50b'') at the end and the fixed rotary ring (32) of the movable rotary plate (34)
), the rectangular area of the cloth clamping member (52) expands as shown in FIG.

Then, the above operation is repeated again.

The above describes two embodiments of the present invention, and various modifications can be made without being limited to these embodiments.

Effects of the Invention According to the present invention, since the cloth clamping members arranged parallel to each other approach at the same time, the operation speed for automatically shrinking the cloth can be further improved.

Therefore, it becomes possible to produce a large amount of droop in a short period of time, and packaging costs can be reduced.
