Description

[Detailed description of the invention] [Industrial field of application] This invention consists of a plurality of conveyance devices each having a plurality of rows of passages arranged in parallel, and the movable member of the conveyance device carries an item placed on the upper surface of the passageway. The present invention relates to a conveyor device that conveys by pushing.

[Conventional technology]

A conveyor system equipped with multiple conveying devices that push multiple rows of items placed on a passageway from the rear using a moving member has the same amount of conveyance per unit time of the conveying devices, and the movement of the items is It is generally widely used because the speed can be changed with a certain degree of freedom.

As a conventional example, there is one described in Japanese Patent Publication No. 44-266150. That is, the conveyor device of this prior art is provided with a passage for guiding articles on the upper surface, an upstream chain that rotates below the passage, a base end connected to the chain, and a distal end connected to both side edges of the chain. an upstream conveyance device having a moving member protruding from the opening, and a downstream chain installed in parallel along both upper side edges of the passageway so that the conveyance device and the upstream end overlap with each other, and an upper surface of the passageway. and a downstream moving member suspended from the chain so as to cross the chain, and when the downstream moving member travels faster than the upstream moving member and overtakes it. The article is moved from the upstream conveying device to the downstream conveying device by moving downward and receiving the article from the upstream moving member. Therefore, it is necessary to provide a large number of peripheral parts such as an operating rod, a control rod, a cam body, and a bullet so that the moving member on the downstream side can move downward, which complicates the manufacturing process and increases costs. I didn't get it.

[Problem that the invention attempts to solve]

For this reason, a conveyor device was devised in which an intermediate conveying device is provided between the upstream conveying device and the downstream conveying device, and this conveyor device is equipped with a moving member that pushes multiple rows of items from behind at the same speed. (Japanese Patent Publication No. 57-16767, Japanese Patent Publication No. 55-11973), but in both cases, if the items are fed unevenly at the starting end of the upstream conveyor, the items may not reach the intermediate conveyor. This uneven state continues until the items are pushed by the moving member, which poses a problem in that it is impossible to perform any processing on the items on the upstream conveyance device.

In addition, as a conveyor device equipped with an intermediate conveying device, as shown in Japanese Utility Model Application Publication No. 55-140019, the base end is connected to a chain spanning below multiple rows of passages, and the tip is opened in each passage. an upstream conveying device having a moving member protruding from the slit; a base end connected to a chain spanning above the passage so that the conveying device and the upstream end overlap; and a distal end pushing the article. A conveyor device has also been devised, which includes an intermediate conveying device having a movable member that moves, and a downstream conveying device consisting of an endless belt installed such that its upstream end overlaps with the intermediate conveying device. However, this is achieved by slanting the passage of the upstream conveyor and installing a regulating rod in the middle.
This configuration eliminates the overlapping condition when items are supplied in an overlapping manner at the starting end. However, in this invention, all the moving members in the upstream and intermediate conveying devices are connected at their proximal ends to chains arranged in each of the multiple rows of passages, so the number of chains increases and the overall device It was inevitable that costs would rise.

Moreover, in both of the designs, no consideration was given to means for smoothly transferring items that are easily damaged at the end of the downstream conveyance device or items that would be inconvenient if they were to overturn to the next process. .

However, this invention was made by paying attention to the problems of the conventional technology, and in a conveyor system in which a plurality of conveying devices are consecutively arranged in a straight path, (a) simultaneously at the starting end; Even if a plurality of supplied items are slightly uneven in the front and back, the distance can be maintained to the extent that they do not interfere with the group of items in the front or rear row.

(b) The movable member can immediately straighten the objects in a horizontal line and transport them.

(c) Items move slowly to the end of the conveyor on the downstream side, and even items that are easily damaged or items that would be inconvenient if they tip over can be smoothly transferred to the next process.

(d) To provide a conveyor device having the above effects with a simple structure and at low cost.

It is intended for this purpose.

[Means for solving problems]

In order to achieve the above object, the present invention provides a guide plate with a plurality of rows of passages arranged in parallel on the upper surface for guiding the article, and is pivoted above or below the guide plate and rotates in the direction of guiding the article. It consists of a chain that extends endlessly over a plurality of moving sprockets, and a moving member that is connected to the chain at predetermined intervals and that pushes multiple rows of items from behind along the path at the same speed. In a conveyor device comprising a plurality of conveying devices, the chains are installed in parallel along both side edges above the guide plate, and a space between the chains is arranged such that the moving member crosses the upper surface of the plurality of rows of passages. a first transport device that is suspended;
The chain is located below each of the plurality of rows of passages and is spanned such that the upstream end overlaps with the first conveying device, and the movable member has a proximal end connected to each chain, a second conveying device whose tip protrudes from a slit provided in each passage; and the chain is installed in parallel along both side edges above the guide plate so that the upstream end overlaps with the second conveying device. and a third conveying device in which the moving member is suspended from both chains so as to cross the upper surface of the plurality of rows of passages, and the first, second and third conveying devices are The intervals between the moving members of the apparatus are sequentially narrowed, and the rotational speed of each chain is sequentially slowed down so that the amount of goods conveyed within a unit time of all conveyance apparatuses is the same.

[Effect]

In this conveyor device, articles are supplied to the starting end of each passage of the first conveying device located at the top, and are guided on the upper surface of each passage by a moving member suspended on a chain so as to cross each passage. to move downwards. During this movement, the article is continuously moved in response to the speed and spacing of the moving members.

When the article is moved by the first conveyor and reaches its end, it is transferred to a second conveyor whose end and start end overlap.

That is, in this second conveyance device, the movable member moves with its tip protruding from the slit in the passage. Then, in the overlapping part of both conveyance devices, both moving members run side by side,
The article is transferred from the moving member of the first conveying device to the moving member of the second conveying device while moving through the overlapping portion of the two. At this time, the moving member of the first conveying device escapes upward when it reaches its terminal end, and the moving member of the second conveying device rises from below at its starting end, so that the two move smoothly without interference. Items can be delivered to.

Furthermore, in the third conveyance device, a moving member having a chain suspended across each path runs alongside the moving member of the second conveyance device, and receives items therefrom. At this time, the movable member of the second conveyance device escapes downward at its terminal end, and the movable member of the third conveyance device descends from above at its starting end, so that they may interfere with each other even at the overlapped portion of the two. There is no.

Therefore, in these first, second, and third conveyance devices, the intervals between the moving members are successively narrowed, and the rotational speed of each chain is adjusted so that the amount of goods conveyed within a unit time of all the conveyance devices is the same. Since the moving members are sequentially slowed down, even if multiple items fed simultaneously at the starting end are slightly uneven in the front and back, the distance can be maintained to the extent that they do not interfere with the group of items in the front or rear row, and the moving member can be moved immediately. Since the items are straightened in a horizontal line, it is possible to process the items immediately after they are fed to the first conveying device.
The row can be transported from the start end of the third transport device to the end of the third transport device without disturbing the row.

Furthermore, since the items move slowly to the end of the third conveyance device, even items that are easily damaged or items that would be inconvenient if they were to overturn can be smoothly transferred to the next process.

Moreover, this conveyor device has two moving members.
Since the structure can be extremely simple, such as by suspending the device from a book chain at predetermined intervals, or vertically connecting it to a single chain at predetermined intervals, the entire device can be provided at low cost.

Further, the moving member 4d is located at a position lower than the top surface of the item 1, and pushes the item 1 from behind.

The second conveying device 5 includes, below the guide plate 2, three rotating shafts 5a installed on the machine frame 3, a chain sprocket 5b fixed to the rotating shafts 5a, and an endless sprocket spanned over these.

Further, the intervals between the moving members 4d, 5e, and 6d of the first, second, and third conveying devices are narrowed in order, and the amount of articles conveyed within a unit time of all the conveying devices 4 to 6 is Each chain 4c so that it is the same
The rotation speeds of ~6c become slower in order. That is,
Each rotation shaft 4a of each conveyance device 4, 5, 6,
5a and 6a are classified into a drive shaft and a driven shaft, respectively, and each drive shaft is connected to the same drive source so as to be interlocked. The number of teeth on each chain sprocket 4b, 5b, and 6b is 12, and for one rotation of chain sprocket 4b, chain sprocket 5b rotates 8/12, and chain sprocket 6b rotates 5/12.

Therefore, it is possible to process the items immediately after they are supplied to the first conveying device 4, and the items can be conveyed to the end of the third conveying device 6 without disturbing the line. It is.

Furthermore, although the conveyance amount of the article 1 in each of the conveying devices 4, 5, and 6 is the same in a unit time, the amount of the article 1 conveyed at the end of the third conveying device 6 is slow.
