Description

[Detailed Description of the Invention] The present invention relates to the production of a slipper sole material by sequentially pasting individually formed cardboard, vinyl chloride, and a skin on the foot shape of the slipper sole material.

Conventionally, the bottom material of slippers has been made by applying glue to the back side of cardboard 1, press-bonding it to the top surface of vinyl chloride 2 (commonly known as Enbi, hereinafter referred to as Enbi), and then applying adhesive to the back side of the vinyl chloride 2, as shown in Figure 1. After the process of applying glue to the skin 2 and bonding it together,
The company was manufacturing finished products for the sole material 4 of slippers. For this purpose, in each process, workers manually apply glue to the entire required surface with a brush or a glue roller, past them together one by one, press them together, and repeat each process in order to form the bottom of the slipper. The material manufacturing process was completed and the finished product was manufactured. This causes problems such as the odor of the glue and physical fatigue due to crimping, which also poses hygiene issues.The entire process relies on the manual labor of workers, resulting in very poor work efficiency such as poor glue application. In addition, there are problems with the instability and uniformity of the finished product depending on the skill level, and on top of that, each process is a separate manual process, so there are problems associated with securing the necessary work space, organizing the work area, etc. Ta.

Implementation of this invention eliminates the need for many workers,
The sole material for slippers was developed to make it easier to secure a work area, to achieve stable high efficiency regardless of the skill level of workers, and to solve the problems of each conventional process, such as stable and uniform finished products. This is a bonding device.

The device is shown in Figures 7 and 8. Gluing roller 54
is normally composed of a lightweight roller body 55 and a soft rubber 56, but the present invention uses a glued roller 54.
The outer peripheral surface of the soft rubber 56 is covered with a shrink film (also commonly referred to as a shrink film, hereinafter referred to as a shrink tube in the text) 57. In addition, U-shaped grooves are carved on both ends of the shaft core to prevent glue from flowing into the bearing, and the gluing roller 54 can be repaired and replaced easily by removing the bearings 59 and 60. It is possible. The glue tank body 61 has an adjustment screw 64 attached to the tank body 61.
Four fixing screws 65 can be used to adjust the positioning and uniformity of the application of glue to the surface of the workpiece.Also, the amount of application can be adjusted stably using the adjustment plate 62. ensure that Further, when not in use, the cover 66 prevents impurities, dust, etc. from entering the surface of the gluing roller 54 and the inside of the gluing tank.

Conventionally, when the glue roller 54 is not in use, the glue adheres to and solidifies on the outer peripheral surface of the soft rubber 56 of the roller, so when removing it at the beginning of work, the outer peripheral surface of the roller is often damaged. There were many cases where it became impossible to use the equipment and hindered the resumption of work.

The present invention secures protection of the outer circumferential surface of the gluing roller 54 by using the shrink tube 57 to cover the outer circumferential surface of the soft rubber 56. It has become possible to prevent deterioration of the material and maintain its softness. For this reason, the difference in the thickness of the cardboard 1, the cardboard 2, and the skin 3 of the workpiece, as well as the difference in the thickness of the soft rubber 5 of the gluing roller 54,
Since the softness of 6 is maintained, it has the effect of being absorbed. In addition, the glue tank body 61 has an adjustment screw 64
The glue tank main body 61 is installed so that the glue is evenly applied to the application surface of the workpiece that has been adsorbed by the adsorber attached foot die 22.
In order to facilitate the adjustment, by using the shrink tube 57 and adjusting the glue tank 61, it is possible to automatically apply glue to the application surface of the workpiece at any time.

Next, the flow of suction and compressed air will be explained with reference to FIG. Adjustment valve 6 from foot type 22 with adsorber
7, filter box 68, filter 69, rotating shaft 1
It is connected to a vacuum pump 52 through two air distribution grooves 15. The adjustment valve 67 adjusts the adsorption force using an adjustment screw part 72, and in particular, in the crimping parts of D and E parts, the adjustment valve 67 is closed by the opening/closing adjustment valve 70, and the adsorption force is adjusted to the adsorbent foot type 22. The finished product 4 is held by suction on the material holding table 42 until the suction is released and the finished product 4 is dropped and stacked and stored. The filter box 68 is equipped with a filter 69 to remove dust from the suction air, and the air distribution groove 1 of the rotating shaft 12 is
5 and the vacuum pump 52 and to ensure smooth rotation of the rotating shaft 12. Compressed air sent from a compressor (not shown) to the air tank 26 passes through the air distribution groove 15 of the rotating shaft 12 and flows into the foot-shaped vertical cylinder 23, which is connected to an electromagnetic solenoid valve attached to the head of the cylinder. By the operation of 71, the foot type up and down cylinder 23 is driven up and down. Also, cylinder 2 for upper and lower foot type
3 can be easily driven independently by operating the changeover switch 72, and fine adjustment at the time of suction is also possible.

As mentioned above, the present invention first sucks and holds the cardboard 1 formed into a regular shape on the foot mold 22 with a suction device, and
During the limited rotation, glue is applied to the back side of the cardboard 1 by the glue roller 54, and when the rotation is finished, the Enbi 2 is pressed and bonded together and adsorbed at the same time, and the glue is applied to the back side of the Enbi 2 during the next 90° limited rotation. After being crimped and bonded to the skin 3 at part D, it is adsorbed, and when the 270° rotation is completed, the adsorption of the finished product 4 is released and dropped to be stacked and arranged on the material holding table 42.

By sequentially carrying out the above steps, we can automate the process of attaching the bottom material of conventional slippers.
By providing this device, it is possible to reduce the number of workers, increase efficiency and stability, improve and standardize the quality of finished products, and facilitate security by reducing the size of the workplace.
