Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a crusher for crushing resin syringes with needles, ampoules, etc.

[Prior Art] As a conventional crusher, a hospital-use crusher such as a synthetic resin syringe has been proposed in Japanese Patent Application Laid-Open No. 176557/1983. This is constructed so that when a resin syringe or the like with a needle is inserted through the inlet, it is crushed by a rotating blade and a fixed blade and stored in a storage box. The input port, the rotary blade, and the fixed blade are arranged with an interval in the horizontal direction, and a feeder is provided between them, and the syringes, etc., input through the input port are crushed by the rotary blade and the fixed blade. I am trying to send it to the department.

[Problems to be solved by the invention] In the above-mentioned conventional technology, the inserted syringes, etc. are sent to the crushing location by the feeder, taking into consideration the safety when inserting the syringes, etc. However, the provision of a feeder increases the cost, and the space for installing the feeder increases the size of the device. Therefore, considering this problem, it has been considered to provide a shutter on the input port side. For example, in the vertical crusher disclosed in Japanese Patent Application Laid-Open No. 61-263660, a shutter for input is installed above the crushing part of the rotary blade and fixed blade. A hopper is provided, and a shutter is provided at the bottom of the hopper.In this vertical crusher, when supplying crushed material to the crushing location,
The shutter must be opened to expose the shredded area to the outside, which poses a safety problem when putting in the shredded material, and if shredding is carried out with the shutter open, some of the shredded material may be exposed. There is a risk that the parts will scatter to the outside from the hopper input port side. In order to prevent this, it is conceivable to provide two shutters at the bottom of the hopper, but in this case, the two shutters must be operated separately, which makes the operation complicated, and There are safety issues such as forgetting to close the door.

Therefore, the object of the present invention is to provide a small and inexpensive crusher that is highly safe, has excellent operability in opening and closing the door.

[Means for solving the problem] The present invention consists of a crushing means provided in the machine frame, a charging hopper provided above the crushing part of the crushing means, and an opening/closing method on the input port side of the hopper. An upper door is slidably provided to open and close the shredding area side located on the discharge port side of the lower part of the hopper, and is shut off when the upper door is opened to load the shredded material. and a lower door that can be opened when the upper door is shut off to supply crushed material to the crushing location, and a lower door that is shielded by sliding in a shielding direction in response to the opening operation of the upper door. and a door interlocking mechanism that opens the lower door by sliding it in the opening direction in response to the shielding operation of the upper door, and a door interlocking mechanism that opens when the upper door is opened to stop the crushing means and operates when the upper door is shielded. and a switch for operating the crushing means.

[Function] When the upper door is opened, the lower door shields the device, and the inserted syringe, etc. is placed on the lower door and stored in the hopper. When the upper door is shielded, the lower door opens and the syringe, etc. falls on the fractured area, and when the upper door is opened, the lower door shields the fractured area, and when the lower door is opened, the upper door shields the crushed area,
Further, when the upper door is opened, the switch is opened to stop the crushing means, and when the upper door is closed, the switch is activated to activate the crushing means.
