CONSTITUTION:When articles 3 to be loaded are supplied in the lump to a conveyor 20 of which height and speed are the same as those of a supply conveyor 32 from the supply conveyor 32, a chain not shown in the drawing elevates the conveyor 20 up to almost the same height as that of a loaded deck 2 by elevating and lowering an elevator stand 15. Then, a shuttle table 16 is advanced to position the down stream end of the conveyor 20 just above the base end of the deck 2. And then, the shuttle table 16 is retreated making the conveyor 20 run to the direction of C and transfer the articles 3 to the deck 2 while restoring to its former position. by repeating this operation, a multi-deck shelf 1 is loaded. The loading ability can be improved by this constitution.

Description

DETAILED DESCRIPTION OF THE INVENTION This invention relates to a loading device for loading objects to be implanted onto a large number of overlapping shelves.

Conventional ultra-heavy implantation devices for loading implanted objects onto a book truck or the like having a large number of vertically overlapping shelves have been known, for example, as described in Japanese Patent Application Laid-Open No. 51-24881. There is. In this device, a carriage that is lowered by a motor is provided in front of a bunk truck, and this carriage supports a frame that is slightly raised and lowered by the operation of a cylinder and a link mechanism. In addition, this frame supports a belt conveyor as a slide that reciprocates in the horizontal direction to approach and separate from the shelves of the book cart. Load. On the other hand, the carriage supports a belt system inserted between the belt conveyors in a comb-like shape, and when the frame is raised, a plurality of implanted objects of this belt system-F are transferred to the belt conveyor all at once. and handed over. Further, one end of a belt system for transferring a load to the belt system is connected to this carriage. In such a loading device, when a plurality of items to be loaded, which have been conveyed through two belt systems, are received by the belt conveyor by the vertical movement of the frame, the belt conveyor advances and the items to be loaded are placed on the shelf. It is to load cargo. In this way, when the object to be loaded is loaded, the carriage and the carriage are raised by one pinch to prepare for the next loading.

However, such a loading device, as mentioned above,
A belt conveyor that loads the implanted material onto the carriage, a belt system that transports the implanted material onto this belt system, one end of the belt system that transfers the implanted material to this belt system, and a large number of mechanisms. Since the carriage 2 is tilted, the weight supported by the carriage 2 increases, and as a result, the speed at which the carriage 2 moves up and down becomes slow.

In particular, once all the shelves of the book cart have been implanted with the objects to be implanted, the book cart is replaced, but at this time, the carriage rises one pinch at a time until it reaches the 1st limit, as described above. Therefore, it takes a long time to descend from this - limit to the F limit. Here, if the material to be implanted is, for example, trend rubber that is extruded from an extruder, cut into predetermined lengths one after another, and continuously supplied, the lowering speed of the carriage is slow, so the belt control Even if the number of tread rubbers on the tread reaches a predetermined number, a situation may occur in which the carriage still cannot reach the lower limit. As a result, trend rubber overflows into the belt system, resulting in a large amount of tread rubber that cannot be loaded and must be discarded. In order to solve these problems, conventionally, two implantation devices were installed for one extruder.
The operation of the implantation device is switched when replacing the book cart. However, in this case, there are problems in that the equipment cost becomes extremely high, a large installation space is required, and the route for loading and unloading the cart becomes complicated.

This invention is intended to solve problems such as problems such as problems such as the problem that due to the low throughput of the implantation device, some objects cannot be implanted, or the need to install an additional expensive and complicated loading device. This solves the conventional problem of not having to do so.

・X This problem lies in the loading device that loads transplanted materials onto a number of overlapping shelves. A support planting means that supports the object to be implanted and loads it onto a shelf, and a support and loading means that is placed stationary near the support implantation means and intermittently loads the object into the support loading means. This can be solved by providing a supply means for supplying the.

First, when loading objects onto the shelf, the objects are supplied from the supply means to the support planting means at the initial position. Next, the support implantation means for supporting the object to be loaded is moved to just before a predetermined shelf by raising and lowering the lifting platform. Next, the article to be loaded is loaded onto the predetermined shelf from the support loading means. Next, the empty support loading means is returned to its initial position by raising and lowering the lifting platform.

In this manner, the lifting platform is repeatedly raised and lowered each time the support implantation means receives an object to be loaded. The above operations are repeated thereafter, and objects to be loaded are loaded from the lower side onto a large number of shelves that overlap below each other. At the time when all the shelves are loaded with objects to be implanted, the support implantation means,
Since the MJ descending platform has reached its upper limit, the distance to return to the initial position is the longest, but as mentioned above, only the support implantation means is supported by the ascending/descending platform. ,
The lifting speed of the lifting table is high, and as a result, the lifting table can return to its initial position before a predetermined number of drops of the material to be loaded are dropped, thereby improving the throughput of the loading device.

Shigaikari Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Fig. 1.2, reference numeral 1 denotes a book trolley, and the base ends of multi-stage shelves 2 stacked below are swingably supported on this trolley 1. Type 2 has a raised free end 45
It can take a standby position A that is inclined to a certain degree and a use position B that is approximately horizontal, and is held in the standby position A by a spring (not shown). Further, when each type 2 is swung to the usage position B, an implanted object 3 such as 1/1/... rubber cut into a predetermined length is loaded. Reference numeral 11 denotes a loading device installed in front of the truck 1, and this loading device 11 has a gate-shaped frame 12. Vertical guides /<-14 are fixed to both legs 13 of this gate-shaped frame 12, respectively, and an A descending platform 15 that can move up and down along the guide bars 14 is fitted into these guide bars 14. ing. Both ends of a carriage 16 are attached to both lifting tables 15, and this carriage 16 is attached to a guide bar 17.
Since it is not kited, the motor 18 is operated to reciprocate within a horizontal plane by a predetermined distance to approach and separate from the trolley 1. 20
is a substantially horizontal conveyor, and this conveyor 20 is attached to the carriage 16. This conveyor 20 is
While supporting a predetermined number of implanted objects 3 from below, the implanted objects 3 are loaded onto the shelf 2 one after another by being driven intermittently by a motor 22 and traveling. The aforementioned carriage 16
, the conveyor 20 constitutes a support implantation means 21 as a whole. Sprockets 25 and 26 are rotatably supported at the upper and lower parts of both legs 13 of the portal frame 12, respectively, and a chain 27 with one end attached to the lifting platform 15 is hung on these sprockets 25 and 26. It has been passed. The sprocket 26 is connected to a rotating shaft of a motor 28 with a reduction gear that is intermittently driven and capable of forward and reverse rotation. Sprocket 25.2G, chain 27 as mentioned above

Between this connecting conveyor 31 and the conveyor 20 in the initial position shown by the solid line in FIG. 1, a supply conveyor 32 serving as a supply means is placed stationary close to the conveyor 20. This supply conveyor 32 is connected to the conveyor 3 to which the implanted object 3 is connected.
When transferring from 1 to the adjacent implanted object 3, it runs intermittently.
At the same time, the distance between the objects 3 to be loaded is adjusted to an appropriate distance, and the objects 3 to be loaded at the adjusted intervals are temporarily pooled until a predetermined number is reached. Thing 3
is supplied to the Conhair 20 in bulk. There are many carts l like the one mentioned above prepared in the factory,
These carts 1 are generally classified into a plurality of types, and each type has different dimensions, such as width and depth. For this reason, the trolley 1 for each type is provided with an identification code such as a bar code for identifying the type. Immediately before the empty cart 1 is carried in front of the implantation device 11, the identification code of the cart 1 is decoded by a decoding device (not shown), and the loading device 11 receives data regarding the dimensions of the type. Sent. Thereby, even if carts 1 of different types are randomly carried in front of the implantation device 11, it is possible to sufficiently deal with this.

Next, the operation of one embodiment of the present invention will be explained.

Now, it is assumed that a predetermined number of objects 3 to be loaded on the supply conveyor 324 are pooled with the phase W interval adjusted by a constant 1.Next, the supply conveyor 32 runs to The cargo to be loaded 3 is supplied in bulk to the container 20''.

At this time, the conveyor 20 runs at the same speed as the conveyor 32 shown in FIG. As a result, as shown in FIG. 3(a), a plurality of implant objects 3 are supplied to the conveyor 20 while maintaining the mutual spacing.

Next, the speed reducer plying motor 28 operates, the chain 27 runs, and ylli? The platform 15 moves up and down (in this embodiment, rises). When the conveyor 20 reaches approximately the same height as the shelf 2 on which the implanted objects 3 are loaded, the top y of the lifting platform 15 stops. do. The state at this time is shown in FIG. 3(b). Next, the carriage 16 is moved forward to approach the shelf 2 by the operation of the motor 18. When the downstream end of the conveyor 20 reaches the loading position located at the base end surface 1- of the predetermined shelf 2, the forward movement is stopped. This forward motion 114
