Description

[Detailed description of the invention] <Industrial application field> The present invention relates to the structure of a belt conveyor with a suction cup that attracts and conveys articles. This invention relates to the structure of a belt conveyor with a suction cup that can be applied to "Belt Conveyor with Suction Cup" (Utility Model Application No. 63-35726).

<Prior art> In order to transfer the object by sucking the object onto a suction cup and moving the suction cup, the suction cup is attached to a chain fed by a chain sprocket via a mounting piece. A conveyor (Special Publication No. 38-15572) is known. On the other hand, compared to other conveyors such as chain conveyors, belt conveyors have the advantage of having a relatively simple structure and requiring less manufacturing and maintenance costs. Therefore, a belt is widely used as a loading surface for the transported object, but this method has a problem in that the belt spins idly and an accurate transport speed cannot be obtained.

<Problems to be solved by the invention> Therefore, the inventor of the present invention focused on the advantages of a belt conveyor, which has a relatively simple structure and requires no manufacturing or maintenance costs. The idea is to devise a new conveyor with a suction cup by using it as a means of moving the suction cup, but as mentioned above, the problem with the belt conveyor itself is that it is not possible to obtain an accurate conveyance speed. .

Furthermore, when installing a suction cup on a belt conveyor, the following problem must be solved.

In order to install a suction cup on the surface of a belt conveyor, there are problems with the die-cutting structure of the mold and the material of the conveyor belt and the suction cup, which are different materials.The suction cup and the belt conveyor cannot be integrated, and they must be separated. Once manufactured, the suction cup must be attached to the conveyor belt.

Possible ways to attach the suction cups to the conveyor belt are to attach them with adhesive or screw them, but these methods not only pose problems in durability, but also
There was a problem that convex parts (suction cup shafts and screw heads) were formed on the back side of the conveyor belt and interfered with the rollers, preventing the conveyor belt from rotating smoothly.

Therefore, the present invention has developed a belt conveyor with a suction cup that can reliably attach the suction cup to the conveyor belt, prevent interference between the attachment means and the rollers, and at the same time provide accurate conveyance speed. For the purpose of providing.

<Means for Solving the Problems> In order to solve the above problems, the present invention provides a belt conveyor having the following configuration.

The belt conveyor of the present invention has a plurality of rollers 7
0 or the like, a conveyor belt 14 hung endlessly between these rotating means, a large number of shafts 15 attached at equal intervals to the back surface of this conveyor belt 14, and a surface of this conveyor belt 14. and a suction cup 13 that extends through the front and back sides of the conveyor belt 14 and is connected to the shaft 15. This shaft 15... is a roller 70
It is arranged parallel to the rotation axis of the rotation means such as the roller 70, etc., and at least one of the rotation means such as the roller 70
Recesses 71 that engage with the shaft 15 are formed in the roller 70 . Then, when the rotating means such as the roller 70 rotates, the conveyor belt 1
The shaft 15 of No. 4 is connected to the recessed portion 71 of the roller 70.
It is characterized by successive entry into

Incidentally, the suction cups 13 do not need to be attached to all the shafts 15, and the necessary number of suction cups 13 may be appropriately selected and attached to the shafts 15. or,
A plurality of suction cups 13 may be attached to one shaft 15.

<Function> In the belt conveyor of the present invention, the suction cup 13 is not directly attached to the deforming conveyor belt 14, but is connected to the shaft 15 attached to the conveyor belt 14, so that it is relatively simple. It becomes possible to securely attach the suction cup. Moreover, when the rotating means such as the roller 70 is rotated, the shaft 15 of the conveyor belt 14 is rotated by the roller 7.
In order to sequentially enter the recesses 71 of 0, both 1 and 1
5 and 70 can be prevented, and the conveying speed of the conveyor belt 14 is regulated by the shaft 15 and the recessed portion 71 of the roller 70, so that an accurate conveying speed can be obtained.

<Embodiment> FIG. 1 shows a front view of a lunch box washer which is an embodiment of the present invention, and the following description will be made based on this figure. However, the dimensions, shapes, materials, relative positions, etc. of the component parts described in this example are
Unless specifically stated, the scope of this invention is not intended to be limited to those only.
This is just an illustrative example.

Broadly speaking, the lunch box washer is the upper conveyor 1.
0, a lower conveyor 20, a shower 30, a conveyor drive motor 40, and a frame 50 that supports these.

The left end 10a of the upper conveyor 10 in the figure is attached to the frame 50 via a spring 11, and is adapted to hang down due to its own weight.

The upper conveyor 10 is a belt conveyor in which suction cups 13 are disposed over the entire length and width on the surface of a conveyor belt 14 that is installed and driven in an endless manner.

The conveyor belt 14 has a plurality of perforated holes 14a...14 arranged in a straight line in the axial direction of the roller 70.
a are bored at predetermined intervals over the entire length, and the suction cups are adjacent to each other at slight intervals. On the other hand, the suction cup 13 has a shaft 13a attached to the tip of the shaft 13a of the suction cup.
A through hole 13b is bored perpendicular to the center line of the hole.

Then, the shaft 13a of the suction cup is attached to the conveyor belt 1.
4 through the drilling hole 14a from the front side,
Furthermore, the shaft 15 is inserted from the back side of the conveyor belt 14 into the through hole 13b of the shaft 13a of the suction cup, which is aligned in the axial direction of the roller 70, and both ends of the shaft are screwed with nuts 15a and 15b, thereby connecting the conveyor belt 14 and the suction cup. 13...13 are fixed.

The rollers 70, 70 at both ends of the belt conveyor 10 have recesses 71 into which the shafts 15...15 are inserted, at positions corresponding to the pitches of the shaft 15.
...71 are provided, and when the belt conveyor 10 is driven, the shafts 15...15 enter the recesses 71...71 of the roller 70 and rotate like the gear pitch of a rod conveyor. (See Figure 3) The suction cup 13 not only has its shaft 13a inserted into a hole 14a made in the conveyor belt 14, but also has a protrusion on the suction wall in the direction of movement (arrow) of the suction cup 13. 13c, and passes through a long hole 14b formed in the conveyor belt 14 so as to be slidable in the traveling direction. (See Figure 2) The right end 10b of the upper conveyor 10 is a frame 50.
It is supported rotatably by a drive motor 40 via a sprocket 12 and a chain 19.

The lower conveyor 20 is a belt conveyor installed from the lower left to the approximate center of the upper conveyor 10, and like the upper conveyor 10, the conveyor belt 1
They have the same structure in which suction cups 13...13 are arranged on the four surfaces over the entire length and width.

The lower conveyor 20 is connected to the sprocket 18a of the upper conveyor 10 via a gear integrally secured to the sprocket 12, and from the sprocket 18a to the chain 1.
8. Drive motor 40 via sprocket 21
, and moves in the same direction as the corresponding surface of the upper conveyor 10 and in conjunction with it. (The illustrated arrows indicate the rotation direction of each part.) Both conveyors 10 and 20 are provided with guides at appropriate positions to control the position of the conveyor belt 14.

The shower 30 is located below both conveyors 20, 30, and sprays water toward the conveyor belt 14 from below.

Next, the operation of this device will be explained.

The upper conveyor 10 and the lower conveyor 20 rotate in synchrony due to the shaft 15 acting like a rod conveyor, and the collected lunch boxes 60
is placed on the left end 20a of the lower conveyor 20 with the lid closed and is conveyed to the right side in the figure.

When it comes to the bottom of the upper conveyor 10, the lunch box 60
is sandwiched between both conveyors 10, 20, the shafts 15...15 of each conveyor 10, 20 serve as a pressing member to press the lunch box 60 against the suction cups 13...13, and the upper conveyor 10 holds the lid 61, The lower conveyor 20 attracts the main body 62.

As the lunch box 60 flows toward the right side in the figure,
The interval between both conveyors 10 and 20 becomes wider,
The lid body 61 and the main body 62 are separated.

When the lid body 61 reaches the upper right end 21b of the lower conveyor 20, it is washed by water discharge from the shower 30.

The main body 62 is the suction cup 13...1 of the lower conveyor 20.
The belt enters the return path while being attracted to 3.

The main body 62, which has entered the return path of the lower conveyor 20 and has been turned upside down, is washed by water discharge from the shower 30.

When the lid body 61 attracted to the suction cups 13...13 of the upper conveyor 10 comes near the right end 10b of the upper conveyor 10, the protrusion 1 provided on the suction part of the suction cup 13
3c is the guide 1 fixed to the upper conveyor 10
7, the suction cup 13 opens and stops suction.

The lid body 61 whose suction has been discontinued falls downward and enters the storage case 51.

The main body 62 enters the return path of the lower conveyor 20 and is turned upside down while being sucked. When the cleaning of the shower 30 is finished, the protrusion 13c provided on the suction part of the suction cup 13 is attached to the lower conveyor 20 as in the case of the upper conveyor 10. When pushed by a detachment member 16 rotatably attached to a guide 17 fixed to the suction cup 13, the suction cup 13 opens and stops suction.

The main body 62 whose suction has been discontinued falls downward and enters the storage case 52.

In this embodiment, an example was shown in which conveyors were provided on the upper and lower sides, and the shafts of both were used as holding members, but of course, only one conveyor may be used and a holding member may be provided on the other, and the shape of the rollers and the shape of the release member However, the present invention is not limited to this embodiment.

Further, the holes formed in the conveyor belt are not limited to those in this embodiment, and may be holes that pass through a plurality of suction cups.
The shaft may be combined with or without a suction cup.

<Effects of the invention> The suction cup-equipped belt conveyor structure of the present invention can improve durability because the suction cup on the surface of the belt conveyor is fixed with a shaft inserted through the shaft of the suction cup.

Furthermore, since the rollers and shaft do not interfere, smooth rotation of the conveyor belt can be achieved.

A further advantage is that the shaft acts like a gear pitch on a rod conveyor, allowing the upper and lower conveyor belts to rotate reliably and accurately in synchrony.

As described above, the present invention provides a useful and practical belt conveyor structure with suction cups.
