Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a heating device for the upper and lower surfaces of a knitted glove collar, and several courses of the collar are heated by a darning thread partially using heat-fusible yarn. A field of application in which the upper and lower surfaces of the collar of knitted stockinette gloves are heated to a temperature at which the heat-melting yarn melts using a rod-shaped heater with a small heat output to prevent the collar of knitted gloves from fraying. It is something that has.

(Prior art) Figure 6 shows a darning thread c using a part of the heat-melting thread.
This figure shows a glove a in which several courses of the collar b are knitted, but since the glove a is entirely knitted by bag stitching, when it is flattened, the upper and lower surfaces of the collar b are becomes double. A device has already been developed that heats the shoe opening b using radiant heat from a heater to prevent the shoe shoe from fraying, but in order to improve efficiency, it is necessary to heat both the top and bottom of the shoe shoe b relatively quickly. shall be. Fig. 7 is a schematic diagram of a conventional device, in which the shoe opening b of a knitted glove a is sandwiched between a chain g and a support plate f, and two rods each having a calorific value of, for example, about 1 Kw are placed above and below the shoe opening b. Type heaters h and h' are used with the applied voltage adjustable.

(Problems to be Solved by the Invention) The problem with the conventional heater heating device is that two rod-shaped heaters h and h' are used as described above in order to make the heating device uniform on the upper and lower surfaces of the shoe opening b. Although,
Each has its own heating habits, and in particular the heating efficiency of the heater h installed above is poor, so experience is required to adjust the calorific value of the rod-shaped heaters h and h'.
Not only in summer, but also throughout the day, the outside temperature and the temperature at the shoe opening B are different in the morning and afternoon, so you can't make adjustments easily. Two rod-shaped heaters with a large calorific value h,
h' is used, the heat radiated from them during the summer heats up the work room, reducing efficiency.

The present invention aims to improve such drawbacks and to develop a heat treatment device that can evenly heat the upper and lower surfaces of a knitted glove opening using a single rod-shaped heater that generates less heat. I did a lot of research.

The present invention focuses on the use of a single rod-shaped heater that generates a low amount of heat and radiates a small amount of heat into the working room.First, as shown in Figure 5, the front side is a vertical front plate 52, and the rear side is a A heater box 51 is manufactured with a rear plate 53 having an arcuate cross-section and a slit 54 at the center of the height of the front plate 52 in consideration of reflection. A rod-shaped heater 55 is provided inside the heater box 51 at the center of the height in front of the rear plate 53, and between the heater 55 and the slit 54, the heater 55 generates heat. When conducting an experiment using the first prototype device equipped with a heat shield plate 56 to prevent direct heating of the shoe opening b, it was found that a large amount of heat escaped from near the upper and lower edges of the slit 54, resulting in insufficient heating and damage to the upper and lower surfaces of the shoe opening b. The purpose of heat treatment by heating evenly could not be achieved. Therefore, as shown in Fig. 5, the slit 54
An experiment was conducted using a second prototype device in which inwardly bent pieces 57, 57 of the heater box 51 were formed on the upper and lower edges of the heater box 51, and the amount of heat stored in the pockets 58, 58' was large, especially due to the heat storage in the upper pocket 58. The upper surface of the shoe opening b was heated excessively, and the heat treatment using the single heater 55 ended in failure. For this reason, when we experimented with a third prototype in which the heater 55 was lowered as shown in FIG. 5, the purpose of uniformly heating the upper and lower surfaces of the shoe opening b was also not achieved. When we investigated the cause of the failure of the second and third prototype devices, we found that the rear plate 53 had an arcuate cross-section to increase heat reflection efficiency and to compensate for the disadvantages of using a single rod-shaped heater with a low calorific value. Therefore, as shown in FIG. 5, the heater box 51 is made into a rectangular cross section, and a slit 54 is provided at the center of the height of the front panel, and an upright heat reflecting plate 59 is installed inside the heater box 51. A fourth prototype device includes a horizontal heat reflection plate 60 and a heat shield plate 56 similar to that shown in FIGS. When an experiment was conducted by making a shoe, it was found that the bottom surface of the shoe opening b was heated to a large extent, and this was also a failure.

The present invention is based on further research based on the thought and error described above, and attempts to create a technical solution that enables the use of a single rod-shaped heater with a low calorific value, which is extremely advantageous both in terms of electricity costs and the work environment. It is something to do.

(Means for Solving the Problems) The present invention aims to solve the problems mentioned in the previous section, and as shown in FIG. A heater box 30 that is long in the direction of transfer is provided in the frame 25 for transporting knitted gloves a knitted with several courses of cuffs b using yarn in one direction, so that the cuffs a face inside from the slits 35. The box has a front plate 31, a bottom plate 32, a back plate 33, and a top plate 3.
4, and the slit 35 is provided in the center of the front plate 31 in the height direction,
Inside the heater box, an upright heat reflecting plate 36 is provided that stands up from the bottom plate 32 near the back plate 33, and the upright heat reflecting plate 36 is inserted into the slit 3 described above.
A substantially horizontal heat reflecting plate 37 is bent from near the upper edge of the top plate 34 to face the slit, and the front edge of the horizontal heat reflecting plate 37 is connected to the inner surface of the front plate 31. A gap 38 is formed between the slits 35 and the upright heat reflecting plate 36 so that the shoe opening b facing the inside does not come into contact with each other.
It is characterized in that a rod-shaped heater 39 with a small calorific value is passed through the inner corner of the heater.

(Function) The present invention has the above-described configuration, and the feed chain 2
The cover b is transferred inside the frame 25 by a transfer device such as 3, 24, etc., which pinches the cover b in a flat state and feeds the cover b in a flat state (such a transfer device is conventionally known), and the front plate of the heater box 30 is A slit 35 provided in the box 31 exposes a certain length to the inside of the box 30, and the heat generated by the rod-shaped heater 39, which includes an upright heat reflection plate 36 and a horizontal heat reflection plate 37, is transferred to the horizontal heat reflection plate 37. Heat treatment is applied to the lower and upper surfaces of the cover b, which passes through the gap 38 in front of the front end edge, to melt the hot-melt yarn by applying heat treatment almost evenly to the lower and upper surfaces of the cover b, while passing through the heater box 30.

(Effects) The present invention has the above-mentioned construction and operation, and only a single rod-shaped heater 39 with a small calorific value is provided inside the heater box 30 constituting the heating section. Although the heat of melting the heat-fused thread is sufficient, most of the waste heat after melting is absorbed by glove a, so the heat is radiated to the outside, increasing the temperature in the work room during summer and impairing work efficiency. Never. However, almost uniform heating of the upper and lower surfaces of the cover b by the single rod-shaped heater 39, which has a relatively small calorific value, is achieved by the heater box developed through much trial and error as described in Fig. 5~. 30, which includes an upright heat reflector 36, a horizontal heat reflector 37, and a bottom plate 32.
The heating wire of the rod-shaped heater 39 is diffusely reflected on the inner surface below the slit 35 of the front plate 31, and the cover b
At the same time as heating the bottom surface of
The upper surface is heated by the radiant heat of the heater that protrudes from the front edge of the horizontal heat reflecting plate 37 to the upper part of the interval 38, and the upper surface of the cover b is heated only by the heat generated by the single rod-shaped heater 39, which has a relatively small amount of heat. The lower surface can be heated simultaneously and almost evenly, and the present invention uses the above-described well-calculated device to simultaneously and almost evenly heat the upper and lower surfaces of the cover b.
Moreover, it has the effect of preventing heat radiation to the outside of the frame 25 as much as possible.
