Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to sorting equipment for sorting products.

Conventional technology For example, in a distribution center or the like, equipment is used for sorting products in order to sort them by shipping party.

Conventional sorting equipment consists of a conveyor, multiple cargo storage devices consisting of fixed shelves installed on the side of the conveyor, and the number of products to be taken from each of these cargo storage devices into storage containers on the conveyor. This system consists of a display device that displays empty storage containers at the start of the conveyor, and the operator, while watching the display, selects the storage container on the conveyor from the back body tube device he or she is in charge of. By taking the designated number of products into the container 14, a predetermined number of products from each country is obtained in the storage container.

Problems to be Solved by the Invention However, in such conventional sorting equipment, the cargo storage device is fixed, so the products are loaded onto one truck, transported to the location of the cargo storage device, and then the products are transferred to the cargo storage device. In addition, if you replenish products after the storage device is empty, the replenishment process will take time, and the sorting process will stop during that time, causing the storage device to become empty. When replenishing products as appropriate beforehand, the storage device must be monitored, making the replenishment work troublesome, and in any case, there is a problem in that the efficiency of the entire work is poor.

Means for Solving the Problems In order to solve the above problems, the sorting device of the present invention includes a conveyor for transporting storage containers for storing products, and a plurality of movable carts placed on the sides of the conveyor. The number of goods to be taken from the storage container into each back pipe or from each storage device into the storage container is The configuration includes a display device for displaying information.

EXAMPLE Hereinafter, an example of the present invention will be described based on the drawings.

Figure 1 is a schematic diagram of the entire sorting equipment in one embodiment of the present invention, (1) shows containers in which products are stored by type (2).
It has a storage location ffl (B) where it stops. Near both sides of the conveyor (1), detectors (3) consisting of, for example, a transmission type photoelectric switch are installed at a predetermined distance above each storage position (B) in the conveyance direction. . A plurality of cargo storage devices (4) are arranged on the sides of each storage position (B) of the conveyor (1), and container storage devices (4) are arranged opposite to these back body pipes (4). A storage room (5) is installed.

(6) is a display installed corresponding to each cargo storage device (4). It displays the number of products to be taken into each back body tube tray (4) from the stored container (2)^. (8) is a display device installed in correspondence with each of the storage positions (B), and the display devices (8) are arranged in a row in correspondence with each storage position (B). The total number of products to be loaded into the plurality of cargo storage devices (4) is displayed. The container storage rack (5) is used to store containers, which will be described later, to be placed on the cargo storage device (4) and to hold products therein. A return conveyor (not shown) is installed above the conveyor (1) to return empty storage containers (2) from the terminal end to the start end of the conveyor (1).

This return conveyor may be installed at an appropriate position, such as below or to the side of the conveyor (1). Further, (9) is a control device consisting of, for example, a microcomputer, and this control device (9) controls the control of the conveyor (1) based on data given in advance and the output signal from the detector (3). Accumulate function and the display (6) and display device (
8) and the display contents.

As shown in detail in FIGS. 2 to 4, the conveyor (1) has a pair of left and right machine frames αO, and a large number of TL rolling rollers αD are arranged between these machine frames α0. At that time, the idling roller αD is rotated by the bearing α3 attached to the roller shaft (2).
is fitted from above into a recess α→ formed on the upper side of the machine frame αO, and a presser member 09 that can come into contact with the upper surface of the bearing 0 is attached to the machine frame αO with bolts or the like. It is removably installed on the [) side. QO is a drive belt that contacts the idling roller (Ll) group from below.
It is continuously driven by a drive device (not shown). A pair of left and right rails (to) are arranged below the machine frame uO via a bracket α force, and a movable platform (a) supported and guided by these rails αυ via wheels α9 is movable in the transport direction. It consists of An upward cylinder device η is attached to this movable base (A), and an elevating body @ seen from the front is attached to its piston rod. Both lower ends of stoppers (goods) with a front view opening shape are connected to both ends of this elevating body (a) via a common pin (a), and at that time, the pins (a) can be freely removed. Therefore, it is difficult to distinguish between the elevating body @ and the stopper.

Guide bodies (A) into which both sides of the stopper (To) are fitted are arranged on the inner surface of the double frame 00. These guide bodies (A) can be attached to and detached from the machine frame αO even in a fixed form. It may be a format. (B) is a high-speed idle roller, which is disposed at the rear of the stopper (the working position of the sakaki), that is, the recess α
(4) is provided with a core cylinder (1) made by attaching bearings (C) that can be freely fitted from above to both ends of the roller shaft, and the lower surface of this core cylinder (to) is attached to the drive belt. It can freely come into contact with the top surface of αG. A pair of left and right rubber rollers c31) are fitted and fixed on the core cylinder (1), and these rubber rollers 6 are distributed to the left and right, avoiding the drive belt Q6, and the outer ends of each are attached to the inner surface of the machine frame 00. is sufficiently close to. Here, the core cylindrical body (1) is set to have a smaller diameter than the idling roller α°C, and the rubber roller Gυ is set to a larger diameter than the idling roller 0. In (2), the upper position that receives the lower surface of the drive belt αG is a roller, and the lower position of the iron is a roller.

The action of this conveyor (1) will be explained. The storage container (2) conveyed by the conveyor device (1) is received by a stopper that protrudes upward, as shown in the imaginary line in Figure 3. . As will be explained in detail later, the storage container (2) is stopped by being at the required storage position (Bl) and the cylinder device @D is driven by a signal from the control device (9).After the work is completed, The cylinder device Q1) is contracted by a signal from the control device (9), and the stopper (C) is lowered as shown by the solid line in FIG. 3 via the elevating body (C). The storage container (2) whose front surface has been opened by the lowering of the stopper (C) is conveyed in a delivery manner by the idle roller αB, and then passed to the high speed idle roller (goods). Here, the high-speed idling roller is of course connected to the drive belt OQ via the core cylinder body (1).
However, since this core cylinder body (1) has a smaller diameter than the idler roller 0, the number of rotations increases than that of the idler roller αB, and the large diameter rubber roller g3D receives the power from the core cylinder body (1). Since it rotates integrally with the body (7), the storage container (2)
Therefore, the rubber roller 6 is transported at a higher speed than usual. Therefore, at the time of completion of delivery, there is a gap between the storage container (2) and the subsequent storage container (2) that is being transported in a predetermined manner.
By raising the stopper again through this interval, the subsequent (second) storage container (2) can be reliably received. In addition, when changing the storage position (B), first, as shown in the imaginary line in Fig. 3, the holding member (to) of the position to be changed is removed, the idler roller is removed, and the same procedure is performed. Then, the high-speed idle roller (5) is also removed as shown by the imaginary line in FIG. Next, the pin (2) is removed, and the stopper is then removed upward as shown by the imaginary line in FIG. After moving the movable base (A) to the desired position, install the aforementioned stopper ■ etc. in the position by lowering it, and then attach the stopper (C) and the elevating body (C) to the pin (I). ) to connect. Thereafter, as described above, the detached idling roller α° C. and the high-speed idling roller) are replaced and assembled to the machine frame αO.

By the way, when transporting the storage container (2), for example, the fourth
