Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a hose feeding roller of a feeding device attached to a hose winding device connected to a power sprayer or the like.

(B) Conventional technology Some conventional drums around which a spray hose connected to a power sprayer, etc. were equipped with a device for automatically aligning and winding the hose. It wasn't.

(C) Problems to be solved by the invention For example, when carrying out control work with a power sprayer, the worker must work while pulling out the spray hose, and the spray hose containing the chemical solution will not weigh itself. In addition, since the rotation resistance and the contact resistance of the drum are added, the longer the spray hose is pulled out, the more labor is required, and the auxiliary worker is required.

From the traverse drive sprocket (22), chain (1
Sprocket (2) fixed to the traverse shaft (10) via the (8)
Aligning machine C installed in the upper part of frame (1) (1) by transmitting power to 5)
The moving base (33), which will be described later, is slid to the left and right. From the delivery drive sprocket (21),
It is transmitted to the sprocket (24) on the delivery roller shaft (15) via the 9), and the delivery roller (23) is rotated only during the delivery via the clutch.

As shown in FIGS. 3 and 4, the aligning machine C and the delivery device D include a traverse shaft (10), a delivery roller shaft, and a cover (30) (30) provided upright on the frame (1) (1). (15), the guide shaft (31) is laid horizontally, and the sliding body (26) is externally fitted to the traverse shaft (10) in the case (32) fixed between the covers (30) and (30). Sliding body (2
A moving base (33) is fixedly attached to 6) via an L-shaped metal fitting (27). The moving base (33) penetrates the feed roller shaft (15), and the tension roller (34) is installed inside the moving base (33), and the feed roller shaft (15) of the present invention is fitted onto the feed roller shaft (15). A spring (36) urges the roller (35) downward so as to come into contact with the roller (35).

As shown in FIGS. 5 and 6, the feed roller (35) is a recess for fitting a pulley-shaped hose (9) on the outer peripheral surface.
(35a) is provided, and the width of the recess (35a) is arranged such that the narrow portion and the wide portion are alternately arranged. The hose (9) is inserted between the recess (35a) and the tension roller (34), and the hose (9) is clamped in a narrow portion to intermittently feed the hose (9). Then, the guide roller (37) is attached to the front end of the moving base (33).
(37) is rotatably arranged and the hose (9) is passed between them,
A guide bearing (39) is fixedly installed under the guide rollers (37) (37) to guide the left and right sliding.

As shown in FIG. 7, the delivery device D is a box (4
The feed roller (35) is installed inside (0), the guide rollers (37) and (37) are projected in the front, the motor (4) is placed on the box (40), and the motor (4) is used. The box (40) is configured to drive the feed roller (35) and the width of the box (40) is adjustable.
(41) It may be fixed on (41) and attached to an existing reel with a winding device as a separate body so that only the feeding device (14) can be removed.

As shown in FIGS. 8 and 9, the guide roller (3
7) Move mounting stays (43) and (43) that pivotally support (37) Base (33)
Pivot them together with a spring (42), and place the micro switches (44) (45) (sensors) on both sides of the bases of the mounting stays (43) (43) and start winding the hose (9). A detector (49) is provided at the end of the nozzle and the end on the nozzle side, and the detector (49) is configured to turn on the microswitches (44) (45) and stop the motor (4) at the end of winding or feeding (The winding start portion is not shown). (46) is a forward / reverse rotation changeover switch, (T) is a timer, and (t) is its contact point so that the motor (4) can be started by operating only during forward / reverse rotation changeover.

(F) Action of the device In such a structure, when the winding signal is transmitted by the wireless device or the switch is manually changed to winding, the motor (4) rotates in the (A) direction and the chain (17) ), The input sprocket (20) is rotated and the drum (3) is rotated, and at the same time, the traverse shaft (10) is rotated via the chain (18) and the moving base (33) slides to the left and right. The hose (9) is wound while being moved and aligned. At this time, the sprocket (24) on the delivery roller shaft (15) is idling due to the clutch.

In addition, when the transmission signal is transmitted by the wireless device or the switch is manually switched to the transmission, the motor (4) rotates in the (B) direction and the input on the sprocket shaft (13) via the chain (17). The sprocket (20) and the delivery drive sprocket (21) are rotated, and the sprocket (24) and the delivery roller shaft (15) are rotated via the chain (19). At this time the sprocket shaft (13)
The drum (3) is free due to the clutch interposed between the drum shaft and the drum shaft.

Then, by rotating the sending roller shaft (15), the sending roller
(35) is rotated, the hose (9) is sandwiched by the narrow recessed portion (35a), and the hose (9) is pressed from above by the tension roller (34) and intermittently fed. At this time, the traverse shaft (10) is also reversely rotated, the moving base (33) is also slid to the left and right, and the drum (3) is also rotated by feeding the hose (9).

(G) Effect of the Invention With the above-mentioned configuration, the present invention has the following effects.

First, since the feed roller can be intermittently fed in a narrow portion, the labor of the operator to pull the hose is reduced.

Secondly, since the feed roller is provided with a wide portion and a narrow portion, the feed roller can be fed regardless of the size of the hose.
