Description

[Detailed description of the invention] This invention is an endlessly jointed conveyor belt consisting of structural rods in which a plurality of cross-shaped interlocking portions are successively protruded from the front and back to form a bend. Regarding the improvement of joint rods for the purpose of

Endless joints of this type of conveyor belt have conventionally been carried out using the structural rods themselves that continuously form the cross-shaped interlocking portions that make up the belt, and the joint configuration is shown in Figure 7. A joining rod 14 having the same configuration as the component rod 12 on which the square-shaped interlocking portion 13 is connected is curved in a square shape, and its both ends are connected to the adjacent left and right ends located at the center of the component rod 12b on the rear end side of the belt. Straddle the two intertwined parts 13b, 13b and hang through,
Both ends of the belt are passed through to one intertwining part 13a located at the center of the component rod 12a on the front end side of the belt, and the intertwining part 15 corresponding to the curved top of the joint rod 14 is connected to the center intertwining part on these front and rear ends. Parts 13a, 13b, 13b
, and both ends are further intertwined with left and right intertwining parts 13a and 1 of the structural rods 12a and 12b on the front and rear ends of the belt.
3b, and sequentially engage each intertwined part 15 of the joint rod 14 having the same configuration as the component rod 12, and finally connect both ends to the component rod 12a or 12b on either the front or rear edge of the belt. They were hung together to form an endless belt.

In an endless belt joined in this way,
In addition to the fact that the endless joint work is very complicated and inefficient, in particular, the square-shaped interlocking part, which is continuously bent and formed with high precision as a joint rod, is attached to the component rods on the front and rear ends of the belt. Due to the engagement of the rod, it becomes distorted in the process of resisting the latent force and bending into a 〓 shape, causing irreversible distortion in the joint rod and impairing the accuracy of the joint rod.This causes distortion of the entire endless belt. There was a serious drawback that the belt could no longer be conveyed smoothly.

Furthermore, this type of endless belt is often used as a conveyor belt, especially in food processing processes, but in this case, for hygiene reasons, it is necessary to remove the belt from the pulley and wash it after each continuous rotation. The work of pulling out the joint rod for endless release during removal work is as troublesome as the above-mentioned joining work, and the repeated engagement and curving of the joint rod for removal can cause irreversible distortion. There was a problem that this increased and the joint rod could no longer fulfill its role as a member of the belt component rod.

This idea was made with the intention of eliminating these problems and developing a highly accurate joint structure for endless belts as conveyor belts. A plurality of convergent vertical bars are bent to protrude in the front-rear direction to form a structural rod, and a large number of structural rods are arranged in parallel in front and back. In an endless belt in which the front and rear ends of the belt are connected in an endless ring by sequentially intertwining and connecting the opposing square-shaped interlocking parts of the component rods, a wide range of tensile force is applied along the width direction of the belt using a wire rod. A joint rod is formed by a horizontally long joint horizontal bar and a leg-shaped joint vertical bar, and has horizontal holes communicating with each other in opposite directions at the tips of the joint vertical bars that face each other. The opposing longitudinal bars are hung over the elbows of adjacent convex intertwined parts on the left and right sides of the component rods that can protrude onto the front and rear ends of the belt, respectively, and are hooked on the front and rear ends of the belt. It is characterized in that the horizontal holes of the joint vertical bars of the joint rods which are exposed from the joints are intertwined in a straight line on the left and right, and the straight connecting rods are connected through a skewer.

Hereinafter, one embodiment of this endless belt will be described with reference to the drawings. Both ends of the horizontal crosspiece 2 having a certain joint length made of metal wire are raised and bent downward on a plane to form sunken elbows 4, 4. Through the vertical beam 3,
3 is formed, and a plurality of intertwined parts forming a tapering shape are continuously formed to protrude in the front-rear direction to form a structural rod 1.
A belt A is constructed by sequentially intertwining and connecting a large number of these component rods 1 arranged in front and in parallel and facing each other in the front and back.

Reference numeral 5 designates a joint rod, which is made of metal wire and has a joint horizontal bar 6 with a constant joint distance on a plane, and vertical joint bars 7, 7 whose both ends are bent downward. 7, 7 are raised through the elbow parts 8, 8, and the tips thereof are circularly bent into a small annular shape, and lateral holes 9, 9 are provided which communicate with each other in an opposing manner.

The joint vertical bars 7, 7 of the joint rod 5 are connected to the bent elbows of the joint portions that are adjacent to each other on the left and right sides on the respective component rods 1a, 1b that can protrude at the front and rear ends of the belt A, respectively. 4, 4, and the connecting vertical bars 7, 7 of the connecting rod 5 hooked to the front and rear ends of the belt A were butted together from the front and back in an interlocking manner, and were aligned on a straight line from side to side. Connecting rod 1 to horizontal holes 9 and 9
0 are connected through a skewer to form an endless belt.

The small annular horizontal hole 9 can be used as a spacer by continuously bending it several times as shown in FIG. 10, 10, and the connecting rods 10, 10 are inserted from both the left and right sides into the horizontal holes 9, 9, which are arranged in a line with each other from the front and back, and abutted against each other, and the joint pipe 11 is made to straddle this abutted portion. It is also possible to insert and fit the outer ends of the connecting rods 10, 10 onto the left and right side edges of the belt to connect them.

In the embodiment in which the joint vertical bars 6 of the joint rod 5 are raised to form the elbow parts 8, 8 in a sunken shape, the joint vertical bars 6, 6 are located at the front and rear end joints on the endless belt surface, as shown in FIG. Joint belt component rod 1, vertical beam 3 of 1,
3, a flat belt surface can be formed, which is effective as a conveyor belt in stabilizing the articles being conveyed.

In addition, as shown in FIG. 6E, a part of the joint rod 5 is made into a hook shape as a whole with a horizontal joint bar and a single vertical joint bar 7a, and a horizontal hole 9a is provided in this vertical joint bar 7a. joint rod 5
In the embodiment a, the joint rods 5a are arranged and hooked to the left and right edges of the belt A, so that the third
Connecting rod 1 inserted into horizontal holes 9, 9a as shown in the figure
Since both ends of the belt can be fixed without being hooked to the belt component rod 1, it is effective in that the belt can be easily hooked on and removed from the pulley.

The structural rod 1 in this invention is mainly made of stainless steel or other non-corrosive metal wire, but depending on the application, it may be made of a hard synthetic resin material or a wire material made of a hard synthetic resin material mixed with carbon or ceramic fibers.・It can be formed from a wire made of any material, such as a wire made of a metal wire coated with a synthetic resin or rubber material, and the pitch of the intertwined part may be the same one connected in an orderly manner. For example, as shown in FIG. 3, only the intertwined portions located on the left and right side edges are formed to be small, and the joint rod 5 is formed accordingly. As shown in Figure 2 and Figures 6A to 6D, the component rods 1 on the front and rear ends of the belt A are shaped like tapered legs.
It is also possible to stably engage the intertwined portions of a and 1b. In addition, the two ends of the connecting rod 10 at the joint between the front and rear ends of the belt are fastened together; one end is used as the head portion and the other end is simply bent and fastened (see Figure 3), and both ends are fastened to the front end of the belt. Alternatively, it may be arbitrarily fixed, such as one that is hooked onto either of the component rods 1a, 1b on the rear end side (see FIG. 2).

As mentioned above, this idea consists of a structural rod in which the wire rods are bent in a continuous crank shape in the front-rear direction, and the opposing intertwined parts are sequentially intertwined. In an endless belt that connects the front and rear ends of the belt in an endless ring shape, the protruding intertwined parts dotted on the front and rear ends of the belt made of this type of wire material can be used without sliding from side to side and within a certain range. In order to transmit the tensile force widely and evenly, both ends of the connecting horizontal bars with a certain joint distance are bent to form the entire shape as left and right connecting vertical bars, and the tips of the left and right connecting vertical bars are bent. The belt is characterized in that the front and rear ends of the belt are joined in an endless ring shape by a joining rod formed with a horizontal hole opposite to the belt and a straight connecting rod.

In this way, the joint vertical bars of the joint rods are passed over the elbows of the intertwined parts of adjacent component rods on the front and rear ends of the belt, and the joints are wrapped around the joints at the elbows of the joint rods. From the endless structure, in which the connecting rods of the connecting rods are butted together from the front and back in an interlocking pattern and the connecting rods are inserted into the horizontal holes aligned in a line to connect them, an endless joint is used to hook and remove the belt from the pulley. By fundamentally changing the conventional joint configuration in which the joint rod and the connecting rod are curved, it is possible to extremely easily insert and attach the joint, and to pull it out and disconnect it. Therefore, these operations can not only be carried out efficiently, but also eliminate the risk of causing irreversible distortion in the connecting rods and connecting rods, thereby eliminating the need to put the endless belt on or off the pulley. To provide a high-precision endless belt with no distortion throughout, ensuring smooth conveyance as a conveyor belt, and having a remarkable effect especially when used as an endless conveyor belt for food processing.

Moreover, the two adjacent elbows of the protruding intertwining parts adjacent to each other on the same end of the front and rear edges of the belt are sequentially hooked from the left and right by the left and right elbows of the articulated joint rod. In order to apply the feeding tensile force evenly to each other in the width direction at each joint rod at each hanging and tying part of the belt joint part, this prevents distortion at the belt joint part due to the driving tension force. Therefore, the driving tensile force acts evenly over the entire endless belt, which has the effect of further ensuring smooth belt transport.
