Abstract

PURPOSE:To provide a smell-less operation and a smooth transfer by automatically performing a series of operations for dropping opened bags onto a next weighing hopper through a hopper feed conveyer by the action of a phototube provided on any position of an automatic transfer device. CONSTITUTION:Two stages of a belt conveyer 1 rotatably ascending to unload bags B are installed under which are installed a stock belt conveyer 2 automatically rotatable forward and backward and a stock tank 2'. At the next position are installed feed-in belt conveyers 3, 3' and at the next position a sorting conveyer 4 is provided on the outer periphery with projection push-up plates 5 at a proper interval for individually sorting bags. At the further next position is provided a hopper feed conveyer 6 which is provided on the upper portion with an automatic bag opening machine consisting of a hydraulic damper 8, upper pressure belt 7 with a weight 9 and lower rough belt 11 with a plurality of rotary saw blades 10. A series of operations for dropping the opened bags B to the next weighing hopper 12 by the hopper feed conveyer 6 are performed automatically by the action of a phototube P provided at any position of this device, so that a smell-less operation is attained.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is capable of transporting a large amount of plastic bags containing diapers and other laundry waste, which are mainly generated from hospitals and other places, into a laundry cart without any human intervention. The present invention relates to a new hygienic and labor-saving device that automatically transports, opens, and feeds the product from the washing machine to the washing machine.

[Prior Art] Conventionally, this type of dirty laundry could be transported by truck and transported to the washing machine, but even then, if there was a traffic jam during transportation, the bags would often collapse due to the pressure between the bags. However, when the bag is torn, it releases a bad odor, which is unhygienic and is disliked by everyone. Improvements in work were requested.

[Problem to be solved by the invention]

This invention was developed by installing photocell tubes at important points on each belt conveyor so that small amounts of laundry can be transported at a time, since when bags containing laundry become jammed during transport as described above, the bags are pushed against each other and the resulting pressure causes the bags to tear. When a large number of bags accumulate, the conveyance stops there, and if the bags are conveyed smoothly, they continue to move.In the final stage, the bags are opened one by one with a rotary saw blade by an automatic opening machine, and the bags are unsealed one by one with a rotating saw blade. Since the waste falls into the weighing hopper at the top of the washing machine, the aim is to ensure smooth and hygienic transport without spreading bad odors into the transport area.

[Means for Solving the Problems] In order to achieve the above object, the conveying device with an automatic opening machine of the present invention is first equipped with an unloading belt conveyor that rotates upwardly, from which the laundry bags are loaded. The belt installed at the lower level drops the material onto a stock belt conveyor that can automatically rotate back and forth, and from there it is transferred to the next feed belt conveyor, where several push-up plates are placed at appropriate intervals on the belt around the outer periphery. A conveyor is installed upward for individual bag sorting, and the laundry bags stacked from this conveyor are received by a hopper feeding belt conveyor installed next, and a hydraulic damper and weight are installed above the conveyor. The series of operations that automatically open the laundry bag by sandwiching it between the Murakami pressure belt and the lower belt with several rotary saw blades, and then dropping it into the next weighing hopper by this hopper feed belt conveyor are performed at various points in the device. This device automatically transports laundry bags to the lower washing machine using the action of a phototube installed in the washing machine.

[Operation] The conveying device configured as described above first operates an unloading belt conveyor, and loads a large amount of dirty laundry plastic bags (approximately 4 kg each, hereinafter simply referred to as bags) collected from various places onto the conveyor. ) are unloaded from the truck.The bags that fall from this conveyor accumulate on the stock belt conveyor installed below, and the conveyor rotates backwards due to the action of the photocell, and when the stock tank is full, it rotates forward and transfers to the next conveyor. Several pieces are sequentially transferred to the feed belt conveyor. From this, on the next upward infeed belt conveyor, the next bag individual sort is dropped onto the conveyor. The bags that have fallen down here are sorted one by one by stainless steel push-up plates attached at appropriate intervals to the wooden boards stretched around the outer circumference of the conveyor, and then pushed up by the rough belt at the top of the next hopper feed conveyor. The bag is then sandwiched between the top and bottom by a hydraulic damper and a weighted pressure belt at the top, the bottom is cut open in several places by several rotating saw blades, and the bag is dropped into the next weighing hopper by a hopper feed conveyor at the bottom. . When a certain amount of bags have accumulated in the weighing hopper, the bottom cover is opened by the action of a phototube, and the laundry is dropped into the lower washing machine, thereby carrying out a series of laundry bags.

〔Example〕

The embodiment will be explained below with reference to the drawings. In Fig. 1, first, the bag (B) that is being rotated up and down is unloaded with a belt conveyor (1) installed in two stages, and the conveyor below this is automatically moved back and forth. Rotatable stock belt conveyor (2)
and a stock tank (2'), and as shown in Figure 2, feed belt conveyors (3) and (3') are installed next to this, and the next level is pushed up at appropriate intervals. Board (

In the drawing, θ′ indicates the double-opening lid on the weighing hopper surface, (M
) is the drive motor of the automatic bag opening machine.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

This device has phototube devices installed on both sides of the starting end of each conveyor, so if the surface group of laundry bags to be conveyed becomes congested and blocks the photoelectrons, the conveyor will stop, and both groups of bags in the path will be blocked. Once the bags are separated, the conveyor starts moving and can automatically transport a series of tube bags. Particularly, the individual sorting of both bags at the rear of the machine is carried out in conjunction with a conveyor and a hopper feed conveyor equipped with an automatic bag opening device. At this stage, the bags are sent one by one, automatically opened, and then sent from the washing machine to the washing machine, creating a bad odor in the work area. Enables hygienic and odorless operation without emitting
It is possible to automatically and labor-savingly process 8 to 10 TQN of dirty laundry per day.
