Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a warehouse for storing or storing packages doffed in textile machines such as spinning machines and automatic winders.

Conventional technology Full packages are doffed and discharged using an automatic winder, etc., and are transported one by one by a conveyor and stored in a warehouse.Then, an appropriate number of packages are taken out, packed in boxes, and shipped. Many systems are automated to store packages and quickly carry them out and carry them in. There are systems in which packages are stored stacked in multiple tiers on a conveyor in a warehouse, or multiple tiers arranged in multiple tiers above and below. There are items that are placed on the conveyor respectively.

Problems to be Solved by the Invention All of the conventional warehouses described above have complicated and expensive equipment for storing packages, and the space within the warehouse cannot be fully utilized. In particular, when a large number of packages are stacked on one conveyor, there is a problem that the number of stacked packages is limited because the lower packages may be deformed by the weight of the upper packages. The present invention aims to solve these problems.

Means for Solving the Problems The present invention involves installing two chains along both side walls of a warehouse.
Packages are respectively placed on a plurality of plates installed between both chains, and the chains are driven to circulate intermittently or continuously by a motor or the like.

A package discharged from an automatic winder or the like and transported is transferred onto the plate from the package entrance of the warehouse, circulated within the warehouse by the drive of a chain, and then transported out of the package exit as appropriate.

Embodiment FIG. 1 schematically shows the inside of a package storage warehouse according to the present invention. ◇ A package inlet (2) and a package outlet (3) are formed on the left and right sides of the warehouse (1), and the above-mentioned inlet and outlet are provided. A package carry-in conveyor (4) and a package carry-out conveyor (5) are installed outside the opening (2) and the carry-out port (3), respectively. Inside the warehouse (1) there is a side wall (6) fζ
A total of seven sprockets (7) are pivotally supported, and the same number of sprockets are placed on the other side wall (not shown) at the same positions as shown in FIG. 1, that is, at positions facing each sprocket (7) on the side wall (6). It is pivoted on. An endless chain (8) is attached to each of the sprockets on each of the side walls, and a number of package support plates (9) each having an arcuate cross section are installed between the two chains (8). The plate (9) is swingably suspended via a connecting arm (12) from pins (7) connected to each chain (8) at regular intervals, and the package (P) is It has a size that allows m pieces to be placed in the direction orthogonal to the plane of the drawing.

Therefore, the warehouse (1) is large enough to contain all the plates (9), and the inlet (2) and outlet (3) are used to store m packages on the conveyors (4) and (5). It shall have an opening surface large enough to allow passage of both at the same time. (13) is a motor that rotationally drives one sprocket (7) via an endless belt (14);
Each chain (8) circulates along each side wall (6) by driving the package support plate (9).
) also circulates within the warehouse (1). At this time, each plate (9
] and the sprockets (7) are arranged so that the packages (P) on the plate do not interfere with each other and leave as little extra space as possible between them, and each pin (11) (11) The interval between is set.

FIG. 2 shows an example of the arrangement of warehouses (11) in a textile factory.

(15) is an automatic winder connected to the conveyor (4) for carrying in the pan cage, and the pipe yarn after spinning is removed from yarn defects by the winder (15) and is wound into a large diameter package (P). It is then dumped and transferred to the above conveyor (
4) The 0 packages CP) that are sequentially discharged upward are conveyed in a line in the direction of the arrow (16) on the conveyor (4), and the first package (P') is stopped by the stopper (17) provided at the end of the conveyor. By being restrained, each package (P) is lined up in a line in front of the entrance (2) of the warehouse (1).A (17) is a photoelectric sensor with a counter installed near the conveyor (4). The stopper (16) is placed at the end of the loading port (2) on the opposite side to the stopper (16), and detects and counts the number of packages (P) passing in front.When the count value of the sensor (17) reaches m When the package loading device reaches the loading port (:2), the package loading device (described later) is activated.
The front m packages (P) are transferred to the package support plate (9) in the warehouse (1). At the same time as the transfer is completed, the counter of the sensor (17) is reset, and the motor
The plate (13) is driven to sequentially feed the plate (9), and the next m packages are prepared to be carried in. The package CP placed on the plate (9) is stored in the warehouse (1
) and reaches the front of the outlet (3), where the plate (9) is transferred onto the package conveyor (5) by a package conveyor (described later). The transferred package CP) moves along the conveyor (5) in the direction of the arrow (
18), packed in a box (19) by an operator, and carried to the subsequent process. The above-mentioned package carrying device is shown in FIG.

Two concave-shaped frames (
21) are respectively fixed, and a package passageway (22) is formed between the frame (21) and the conveyor (4). An air cylinder (23) is supported by a shaft (24) near each frame (21), and a shaft (25) is rotatably installed between both frames (21).Each cylinder (23) The levers (27) to which the shafts (25 and ζ are fixed) are respectively connected to the piston rods (26), and an abbreviated arm (28) is located near the inside of both levers (27). 25)
Furthermore, a package carry-in plate (29) is fixed between both arms (28). Cylinder (23)
is activated when the counter of the sensor (17) counts up, causing the piston rod (26) to retract. The arm (28) is normally connected to the package passageway (22).
As the piston rod (26) retracts, it rotates to the position shown by the two-dot chain line, and the conveyor (
4) The above m packages CP) are simultaneously pressed and rolled into the warehouse (1) through the package entrance (2). At this time, an empty package carry-in plate (9) is located at a position indicated by (9b) near the carry-in entrance (2), and all of the packages CP) are transferred onto the plate (9). The plate (9) has an arcuate shape with a concave upper surface, and is suspended from a pin (11) located at a distance close to the diameter of the package CP) from the plate (9). Since (P) has a cylindrical or conical shape, the plate (9) stably positions the package (P) at the center position while swinging slightly. Immediately after retracting the piston rod (26), the cylinder (23) returns to its original extended state as shown by the solid line, thereby causing the arm (
28) retreats to its original position, and the frame (21)

8) starts traveling in the direction of arrow (32) and reaches position (9b).
When the plate (9) at the next lower position (9a) rises and reaches the position (9b), the limit switch (9) fixed from the warehouse side wall (6) via a frame (not shown) is
33) comes into contact with the pin (11) at the position (9b) and detects that the plate (9) has reached the position (9b).
(34) on the same frame as the limit switch (33)
A reflective photoelectric sensor (34) is provided with a 0 switch (33) for detecting whether or not a package (P) is present on the plate (9) at the position (gb). When the sensor (34) turns on at the same time, the package (P) is already placed on the plate (9), so it is determined that the package cannot be carried in, and the motor (13)
continues to drive, and when the switch (33) is turned on, the sensor (3
4) is OFF, since there is no package CP on the plate (9), it is determined that the package can be carried in, and the drive of the motor (13) is stopped to wait until the next package is carried in.

Figures 4 and 5 show the structure of the package support plate (9) and the package unloading device. Figure 5-shaped frames (36) are fixed to the warehouse side walls (6) at both ends of the package unloading port (3). , both frames (36)
A shirt (37) is rotatably supported between them.

The shirt (37) has a package delivery plate (39) with comb-shaped teeth (38) formed at the end located inside the warehouse.
An arm (41) is fixed to one end of the shirt (37). At the end of the arm (41), a stopper (43) biased downward in FIG. The locking piece (44) is inserted into the hole (45) formed in the side wall (6) when the package unloading plate (39) is in the horizontal position (39a) shown by the solid line in FIG. It is fitted by the force of the spring (42) and prevents the above-mentioned play (39) from rotating downward. (46) is the package unloading play (39).
