以上の実施例、比較例および参考例を比較検討する。まず、桟部材を接合部に接着した効果について、実施例１と比較例１，実施例２と比較例２、実施例３と比較例３，実施例５と比較例４、実施例６と比較例５との対比により明らかなように、接合部破断強度は、桟部材を有する実施例は桟部材を有しない比較例に比して、１２〜２５Ｎ／ｍｍ（１．６〜２．２倍）大きくなる成果が得られている。なお、実施例４と参考例１との対比では、ほぼ同じ接合強度（５３，６５Ｎ／ｍｍ）であるにも係わらず、フィンガーのステップ長さ（ｗ’）では大きな差（実施例＝３０ｍｍ、参考例１＝８０ｍｍ）があり、実施例４では成形作業が容易となる効果がある。
【００３７】
ステップ長さによる差は、実施例１，実施例３，実施例４の比較でも見られるようにステップが長くなるに従って接合強度は大きくなり、また、実施例１と実施例２との比較により裏側補強布を貼り付けることにより、約５Ｎ／ｍｍ接合強度が大きくなり、実施例１と実施例６との比較により判るように桟部材に底部補強布を貼り付けることにより、約１０Ｎ／ｍｍ接合部破断強度が大きくなることが見られる。

以上説明したことから明らかなように、本発明の桟付樹脂ベルトおよびその製造方法には、次のような優れた効果がある。
【００３９】
請求項１に記載の桟付樹脂ベルトでは、ベルト本体の接合部に重ねて逆Ｔ字型桟を接着することにより、逆Ｔ字型桟の底部が接合部の破断強度を補強する効果があり、必要な接合強度を実現するためには、従来のステップ長さを大幅に短くすることができ、フィンガー成形時間を大幅に短縮できる。更に、底部の幅をステップ長さより大きくすることにより、使用時にフィンガーの先端が浮き上がることを防止する効果がある。具体的には、ベルト本体の接合部に逆Ｔ字型桟を接着することにより、同じ長さのフィンガーでは接合強度が１．５倍を超え、同じ接合強度ではフィンガーは短くなり成形作業は簡単になる。
【００４０】
請求項２または３に記載の桟付樹脂ベルトは、接合部裏面に裏側補強布を、または逆Ｔ字型桟の底部に底部補強布を貼り付けることにより接合強度は一層改善される。
【００４１】
請求項４に記載の桟付樹脂ベルトの製造方法は、ベルト本体の接合と、桟部材の接着を同時に行うことにより、加工時間が短縮されるとともに、従来の繰り返し加熱された接合部が一回の加熱となり、接合部が熱劣化することが防止される。また、桟部材底部の幅がステップ長さより大きいので、接合部全体が均一に加熱され接合強度の低下を防止する。
【００４２】
請求項５に記載の桟付樹脂ベルトの製造方法は、裏側補強布を接合時に同時に貼り付けるので、裏補強布接着のための特別の工数を必要としない効果がある。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a resin belt provided with an inverted T-shaped crosspiece (also referred to as a crosspiece member) attached to a belt surface used for light weight / inclined conveyance or light weight / constant pitch conveyance, and both ends of the belt body. At the same time, the present invention relates to a manufacturing method for bonding a beam member.
[0002]
For example, as shown in a side view showing a use state in FIG. 2, the crosspiece resin belt according to the present invention has the crosspiece members 2 attached to the belt surface of the belt body 3 at predetermined intervals determined by the application, and the drive roller 12 is provided. And driven roller 13 to rotate in the direction of arrow y. The conveyed object 15 is supplied from the conveyed object supply position 30 for each crosspiece 2 and is sent out at the transfer destination position 31. This resin belt 1 with a crosspiece is preferably used when the conveyed articles 15 are conveyed at a constant pitch or when the conveyed article supply position 30 and the transfer destination position 31 have a considerable difference in height (inclined conveyor).
[0003]
[Prior art]
2. Description of the Related Art Conventionally, a resin belt with a crosspiece forms a belt main body of a predetermined length, and the belt ends are joined according to the dimensions of individual conveying means (conveyors) to be used as an endless conveying belt of a predetermined length. Usually, a so-called lap joint method and a finger joint method are used for this joining method.
[0004]
In the wrapped joint method, as shown in a plan view of the joint in FIG. 3A and a sectional view of the joint in FIG. x) The tape is cut into a tapered shape, and the cut belt ends 3 ′ and 3 ″ are overlapped and joined. In the joining operation, the cover material 4 of the cut belt end 3 ′ is peeled off and removed from the core body 5, and a necessary adhesive is overlapped and laminated between both belt ends 3 ′ and 3 ′ for heat bonding ( For example, see Patent Document 1).
[0005]
In the finger joint method, as shown in a plan view of the joint portion in FIG. 4 (a) and a side view of the joint portion in FIG. 4 (b), a finger having such a shape that both ends of the belt body 3 can be fitted to each other. 8 ′, 8 ″, and the corresponding fingers 8 ′, 8 ″ are abutted, and the cover material 4 and the back side reinforcing cloth 6 are applied to one surface thereof and pressurized and heated to be joined (for example, see Patent Document 2) ). The joint may be perpendicular to the belt length direction or inclined. In the finger joint method, the step length w 'of the fingers 8' and 8 "is often increased in order to increase the joint breaking strength.
[0006]
On the other hand, the cross member is an inverted T-shaped cross bar as shown in FIG. 5 which is a cross-sectional view of the cross member 2 attached to the joint portion 22 in the belt length direction. 4 is adhered to the surface. The beam member 2 is attached in a direction (width direction) whose length direction is perpendicular to the belt length direction (arrow x). The crosspiece 2 is formed mainly of an elastic body such as polyurethane or polyvinyl chloride.
[0007]
In the wrapped joint method, a step (difference in thickness) is likely to occur between a joint portion and a portion other than the joint portion, and the joint is inclined with respect to the belt length direction (see FIG. 3A). 2 is usually attached perpendicular to the belt length direction (see FIG. 1 (a)), so it becomes difficult to strongly attach the inverted T-shaped crosspiece to the joint due to the step. In addition, a welder or a hot press is often used to join the belt ends 3 ′ and 3 ″ or to bond the beam member 2 to the belt body 3. If the bonding to the belt body 3 is performed at the same location, the thermal load at the joint may be approximately doubled and the joint breaking strength (also referred to as joint strength) may be reduced. A crosspiece is attached.
[0008]
Furthermore, cutting the belt ends 3 ′, 3 ″ into a long-step finger shape requires a high level of skill and requires a long time.

[Problems to be solved by the invention]
The present invention greatly reduces the step length (refers to the length of the finger (corrugated) portion of the finger joint) when the end of the belt body is joined by a finger joint method to form an endless resin belt with a crosspiece. A resin belt with a crosspiece that facilitates the joining work, adheres the inverted T-shaped crossbar while ensuring the necessary bonding strength, and does not peel off the end of the finger even after long-term use. The aim is to provide a method.
[0011]
[Means for Solving the Problems]
In order to solve the above-mentioned problem, in the resin belt with a crosspiece according to claim 1, both ends of the belt body are finger-joined, and a plurality of inverted T-shaped crossbars are provided on the belt surface including the finger-joined joint. A bottom of the inverted T-shaped bar is bonded to the belt surface of the finger-joined joint, and the width of the bottom is adjusted by the step of the finger-joined joint. It is characterized by being wider than the length.
[0012]
By bonding an inverted T-shaped bar having a bottom width larger than the length of the step to the finger-joined joint (also simply referred to as a joint), the end of the finger is fixed at the bottom of the inverted T-shaped bar. When covered and used as a transport belt, the ends of the fingers do not come into contact with the transported object or the like and do not peel off even after long-term use.
[0013]
The bottom portion of the inverted T-shaped bar functions as a reinforcing member by bonding to the joint portion of the belt body, so that the necessary joint breaking strength can be secured even if the length of the finger is short. In other words, the joints where the finger joints are formed have cores cut and the heat history is large, so that the strength is usually lower than the parts other than the joints. However, the joints are reinforced by the bottom of the inverted T-shaped bar. Even if the finger joint is performed in a short step, the required joining strength can be obtained. The necessary joining strength is designed according to the designed conditions for carrying the resin belt with crosspieces (such as the carrying distance, speed, and inclination).
[0014]
The crosspiece resin belt according to claim 2 is characterized in that a reinforcing cloth is attached to the back surface of the finger joint portion. By attaching a thin reinforcing cloth such as canvas to the back surface of the joint, the strength of the joint is further enhanced.
[0015]
According to a third aspect of the present invention, there is provided a resin belt with a crosspiece, wherein a bottom reinforcing cloth is attached to a bottom adhesive surface of the inverted T-shaped crosspiece. By attaching the bottom reinforcing cloth to the bottom of the inverted T-shaped crosspiece mainly composed of an elastic body, the tension applied to the belt joint can be borne by the bottom reinforcing cloth to further improve the bonding strength. .
[0016]
In the method for manufacturing a resin belt with a crosspiece according to claim 4, both ends of the belt body are finger-joined, and a plurality of inverted T-shaped crossbars are provided at intervals on the belt surface including the finger-joined joint. A method for manufacturing a resin belt, comprising cutting and butting both ends of a belt body to be finger-joined into a finger shape capable of being fitted to each other, and forming a finger step on the belt surface of the finger-joined joint. After overlapping the bottom of the inverted T-shaped bar having a bottom wider than the length, the finger joint portion and the inverted T-shaped bar are mounted on a joining device that pressurizes and heats, and is heated by pressing. The joint operation of the belt main body and the operation of bonding the inverted T-shaped crosspiece to the belt main body are simultaneously performed.
[0017]
Since the inverted T-shaped crosspiece is adhered at the same time as the belt end is joined by the finger joint method, the heat load on the joint can be reduced by about half, and the joining strength is improved. Further, since the joint portion is reinforced by the inverted T-shaped bar, a necessary joint strength can be obtained even if the length of the finger is shortened. By shortening the fingers, the end of the belt is cut to form the fingers, and the operation of butting these fingers together without any gaps can be done with a small number of man-hours, in a short time, and easily by an unskilled person. In addition, by making the finger length shorter than the width of the bottom of the inverted T-shaped bar, the end of the finger is covered by the bottom of the inverted T-shaped bar, and the finger can be prevented from being peeled off by running.
[0018]
The method of manufacturing a resin belt with a crosspiece according to claim 5, wherein the operation of attaching the back side reinforcing cloth to the back surface of the bonding portion, the bonding operation of the belt main body, and the bonding operation of the inverted T-shaped crossbar are simultaneously performed. It is possible to reduce the number of bonding steps and to suppress the thermal deterioration of the joint.
[0019]

FIG. As shown in FIG. 1B, the belt body 3 is provided with a cover material 4 made of an elastic material such as polyurethane (also called PU) or polyvinyl chloride (also called PVC) on the upper surface of a canvas core body 5 having a predetermined strength. Laminated. As shown in FIG. 1A, the belt end of the belt main body 3 is cut into a fittable finger shape having a width w and a step length w ′, and the respective fingers 8 ′ and 8 ″ are abutted. A joining portion 22 of the belt body 3 is formed, and the surface of the joining portion 22 (referred to as a conveying surface, see FIG. 1B) has a length corresponding to the width of the belt body 3 and a width Wt. Thus, the bottom portion 20 of the cross member 2 having an inverted T-shaped cross section is bonded to the bottom portion 20. In the resin belt with a cross bar according to the present invention, the width (Wt) of the bottom portion 20 of the cross member 2 is The finger 8 ', 8 "is designed wider than the length w'.
[0020]
As the bonding means and the bonding means, a bonding apparatus including a lower pressing plate (not shown) having a flat upper surface and an upper pressing plate having a lower surface formed with a mold corresponding to the upper surface of the inverted T-shaped bar 2 is provided. Used. The beam member 2 is superimposed on the formed joint portion 22, attached to the above-mentioned joining device, and heated and pressed for joining, and at the same time, the beam member 2 is adhered to the joint portion 22. In addition, it is preferable to use a high-frequency heating unit that suppresses the flow of the cover member 4 and generates internal heat necessary for joining as a heating unit of the joining device. Further, in order to improve the bonding strength of the bonding portion 22, the bottom reinforcing cloth 21 may be attached to the upper surface of the bonding portion 22 and the back side reinforcing cloth 6 may be bonded to the lower surface as shown in FIG. is there. The bottom reinforcing cloth 21 may be attached to the bottom 20 of the inverted T-shaped bar 2 in advance.
[0021]
The width w and length w 'of the fingers 8' and 8 "and the width (Wt) of the bottom 20 of the crosspiece 2 are varied, and the presence or absence of the back side reinforcing cloth or bottom reinforcing cloth and the material of the cover material 4 are combined. Examples and comparative examples are shown below.
[0022]
[Example 1]
As shown in FIG. 1 (b), the structure of the belt body 3 is such that a polyester sheet having a thickness of 0.3 to 0.6 mm and a strength of 50 to 200 N / cm is coated on a polyurethane sheet having a thickness of 0.2 to 1.0 mm. To form a belt body 3 having a thickness of 0.5 to 1.5 mm. Both ends of the belt body 3 are formed into a finger shape (finger 8, 8 ″) having a width w = 10 mm and a length w ′ = 10 mm, respectively. ), And these fingers 8, 8 ″ are joined to form a joint 22. The bottom of a reverse T-shaped crosspiece made of polyurethane having a bottom width Wt of 20 mm is overlapped on the belt surface of the joining portion 22 and sandwiched by a joining device equipped with high-frequency heating means. Was oscillated and heated for 20 to 60 seconds, and the joining of the joining portion 22 and the bonding of the crosspiece member 2 were simultaneously performed by thermal fusion (in Example 1, the back-side reinforcing cloth 6 shown in FIG. Not used).
[0023]
The method of measuring the breaking strength of the joint 22 is as follows. A strip having a width of 2.5 cm and a length of 30 cm long in the belt length direction centered on the joint 22 is subjected to a tensile test using an Amsler tensile tester to measure the joint strength (N / Mm) was measured (JIS-K6322). Table 1 shows the above joining conditions and evaluation results. The numerical values in Table 1 use the above units.
[0024]
[Example 2]
Bonding was performed in the same manner as in Example 1 except that the back side reinforcing cloth 6 was attached to the bonding portion 22 (see FIG. 1B), and evaluated. Table 1 shows joining conditions and evaluation results.
[0025]
[Examples 3 and 4]
Bonding and evaluation were performed in the same manner as in Example 1 except that the step length w ′ and the bottom width Wt of the crosspiece member were changed. Table 1 shows joining conditions and evaluation results.
[0026]
[Example 5]
Bonding and evaluation were performed in the same manner as in Example 1 except that the material of the crosspiece was PVC, and the bonding conditions and evaluation results are shown in Table 1.
[0027]
[Example 6]
Joining and evaluation were performed in the same manner as in Example 1 except that the bottom reinforcing cloth 21 (see FIG. 5) was provided at the bottom of the crosspiece member. Table 1 shows the joining conditions and the evaluation results.
[0028]
[Comparative Example 1]
Joining and evaluation were performed in the same manner as in Example 1 except that a bar member was not used, and an upper pressing plate having a flat lower surface was used as an upper pressing plate of a joining device used at the time of joining. Table 2 shows joining conditions and evaluation results. Shown in
[0029]
[Comparative Example 2]
Table 2 shows the joining conditions and the evaluation results, except that the cross member was not used, and the joining device was used in the same manner as in Example 2 except that the lower surface of the joining device used at the time of joining was flat. Shown in
[0030]
[Comparative Example 3]
Joining and evaluation were performed in the same manner as in Example 3 except that a bar member was not used and an upper pressing plate having a flat lower surface was used as an upper pressing plate of a joining device used at the time of joining. Table 2 shows joining conditions and evaluation results. Shown in
[0031]
[Comparative Example 4]
Joining and evaluation were performed in the same manner as in Example 5 except that a bar member was not used, and an upper pressing plate having a flat lower surface was used as an upper pressing plate of a joining device used at the time of joining. Table 2 shows joining conditions and evaluation results. Shown in
[0032]
[Comparative Example 5]
Joining and evaluation were performed in the same manner as in Example 6 except that the upper pressing plate having a flat lower surface was used as the upper pressing plate of the joining device used at the time of joining without using the cross member, and the joining conditions and the evaluation results were shown in Table 2. Shown in
[0033]
[Reference Example 1]
Bonding and evaluation were performed in the same manner as in Comparative Example 1 except that the finger shape was set to a width w = 15 mm and a length w ′ = 80 mm, and the bonding conditions and evaluation results are shown in Table 2.
[0034]
When the bar member 2 is bonded to the surface of the joint with the long fingers, the step of the finger becomes larger than the width Wt of the bottom portion 20 of the bar member 2 as shown in FIG. When bonded, a part of the bonding portion 22 corresponding to the bottom portion 20 is heated and melted twice, and there is a problem that the bonding strength is reduced. Also, the tips of the fingers 8 ′ and 8 ″ protruding beyond the width Wt of the bottom of the crosspiece 2 may rise during use and cause a reduction in bonding strength.
[0035]
[Table 1]

[0036]
[Table 2]

The above examples, comparative examples and reference examples will be compared and studied. First, with respect to the effect of bonding the cross member to the joint, the effects of Example 1 and Comparative Example 1, Example 2 and Comparative Example 2, Example 3 and Comparative Example 3, Example 5 and Comparative Example 4, and Example 6 were compared. As is clear from comparison with Example 5, the joint breaking strength was 12 to 25 N / mm (1.6 to 2.2 times) in the example having the cross member compared to the comparative example having no cross member. ) Greater results have been obtained. In addition, in comparison between Example 4 and Reference Example 1, although the bonding strength was almost the same (53, 65 N / mm), there was a large difference in the step length (w ′) of the finger (Example = 30 mm, Reference Example 1 = 80 mm), and Example 4 has the effect of facilitating the molding operation.
[0037]
As can be seen from the comparison between Example 1, Example 3, and Example 4, the difference due to the step length increases the bonding strength as the step lengthens. By attaching the reinforcing cloth, the joining strength is increased by about 5 N / mm. As can be seen from the comparison between Example 1 and Example 6, by attaching the bottom reinforcing cloth to the cross member, the joining strength is increased by about 10 N / mm. It can be seen that the breaking strength increases.
[0038]
【The invention's effect】
As apparent from the above description, the resin belt with crosspiece and the method of manufacturing the same according to the present invention have the following excellent effects.
[0039]
In the resin belt with a crosspiece according to claim 1, the bottom of the reverse T-shaped crosspiece has an effect of reinforcing the breaking strength of the joint portion by bonding the inverted T-shaped crosspiece on the joint portion of the belt body, In order to achieve the required bonding strength, the conventional step length can be greatly reduced, and the finger molding time can be significantly reduced. Further, by making the width of the bottom portion larger than the step length, there is an effect of preventing the tip of the finger from floating during use. Specifically, by bonding an inverted T-shaped crosspiece to the joint of the belt body, the joint strength exceeds 1.5 times for fingers of the same length, and the fingers are shorter for the same joint strength, making molding work easier. become.
[0040]
In the resin belt with a crosspiece according to the second or third aspect, the bonding strength is further improved by attaching a backside reinforcing cloth to the back surface of the joint or a bottom reinforcing cloth to the bottom of the inverted T-shaped crosspiece.
[0041]
In the method for manufacturing a resin belt with a crosspiece according to the fourth aspect, by simultaneously performing the joining of the belt body and the bonding of the crosspiece member, the processing time is shortened, and the conventional repeatedly heated joint portion is formed once. Heating is performed, and the joint is prevented from being thermally degraded. Further, since the width of the bottom of the crosspiece member is larger than the step length, the entire joint is heated uniformly, thereby preventing a decrease in joint strength.
[0042]
According to the method of manufacturing a resin belt with a crosspiece according to the fifth aspect, since the back side reinforcing cloth is simultaneously attached at the time of joining, there is an effect that no special man-hour for bonding the back side reinforcing cloth is required.
