Definitions
- the present invention relates to an arrangement for a goods hoist which comprises an operating control capable of being actuated by a driving device and situated between a load device and driving devices.
- the principal object of the present invention is in the first place to make available an arrangement of the kind described above which is simple and which functions efficiently without the need for great muscle power on the part of the user.
- Fig. 1 shows a side view of a load hoist in accordance with the invention
- Fig. 2 shows a section through the hoist along the line II—II;
- Fig. 3 shows a part of the operating control included in the hoist arrangement
- Fig. 4 shows a further design of an operating control.
- An arrangement for a goods hoist 1 of a kind which is suitable for use on frequently recurring occasions for the lifting of loads rapidly and conveniently without the need for great physical effort and, for example, for positioning the load in a process machine or on a fixture or stack of pallets, etc., so that the user experiences the hoist 1 as if it were working in a so—called 'weight—less* state when working both with and without a load, which contains a solenoid motor 2 or some other suitable driving device so arranged as to be controlled by a transmitter contained in an operating control 3 capable of manual actuation and capable of connection to it.
- Suitable for use as the. driving device 2 are a solenoid motor, a d.c.
- the operating control 3 is situated between said motor and/or coupling which functions as a driving device 2 and a load device 6 of an appropriate kind which operates, for example, with a number of vacuum devices, electro-magnets or clamping or gripping devices, etc. Said operating control 3 is executed preferably in the form of a handle fitted to a rod 7 or some other form of connection acting between the load device 6 and the driving device 2 and attached to a line 8.
- the line 8 is capable of being wound onto a line drum 9 so arranged, for example via a geared drive 10, as to be driven by said driving device 2.
- the operating control 3 is suitably situated at the free end 8A of the line 8, whilst the other end 8B of the line is capable of being connected to the drum via a line locking arrangement 11 in a previously disclosed fashion.
- a solenoid motor 2 which is a multi—pole three—phase motor with a special winding configuration, permits a
- a number of force transmitters 12, 13 or other means which enable recording to take place of the movements imparted to the handle by an operator in relation to the necessarily downward movement of the load in question.
- Said manual force which is required in order to actuate, for example, two piezoelectric sensors 12, 13 incorporated in the handle 3 in order to achieve the desired adjustment and holding of the load is small, usually of the order of 20-50 g, and this force may also be adjustable in relation to the torque of the motor.
- the two piezoelectric crystal sensors 12, 13 situated in the handle 3, which serve as force sensors, can be capable of connection to one another and to the handle 3 and a component 7A attached to the rod 7 by adhesive bonding, and may be capable of being activated after actuation of an actuating button 14, etc.
- the signal from the upper sensor 12 is so arranged as to be proportional to the force imparted to the handle 3 in an upward sense 15, whilst the signal from the lower sensor 13 is similarly proportional to the force imparted to the handle 3 in a downward sense 16.
- the force applied to the handle 3 is allowed to control a ramp generator, which in turn is so arranged as to control the torque of the motor, for example, in which case, if a force is applied to the handle 3, the torque will increase at a rate which is proportional to the forces concerned.
- the ramp generator will adopt a value such that the torque will correspond precisely to the load on the hoist, which means that the handle 3 can be released when in this position without the load exhibiting any tendency to move.
- the friction of the system thus constitutes the range of equilibrium.
- a safety function which means that the load device will be prevented from releasing the load whilst a torque is being applied to the motor 2 or to some other driving device, may be pre—programmed into the electronics, etc., so that a fall arrester brake, for example of the spring—loaded electro—magnetic type, may be fitted to the hoist arrangement 1 for the purpose of arresting the rotation of the line drum in the event of failure of the power supply.
- the arrangement 1 is preferably so arranged as to be controlled by specially developed electronics which control three triacs, whereas the motor torque is regulated automatically by means of so—called switched voltage control after actuation of said sensors 12, 13.
- the variant of an operating control 103 illustrated in Fig. 4 consists of a handle which is movably accommodated on a rod 107, which, via a ball—and—socket joint 150 and a line locking device 151, is attached to a line 108.
- Attached to the rod 107 is a handle cover 152 which supports on each inside part of the upper and lower cover components 152A, 152B a sensor 1.12, 113, preferably of the type described above and preferably attached by means of double—sided tape 153.
- a tongue—shaped component 107A Projecting laterally from the handle 103 and attached to the handle 103 is a tongue—shaped component 107A, which can support rubber plugs 154, 155 or other suitable actuating devices facing towards the sensors 112, 113 and capable of interacting with same, and is so arranged as to accompany the handle 103 as it is moved along the rod 107 in the intended direction, in so doing being able to actuate said sensors 112, 113 by means of said rubber plugs 154, 155, etc., so as to cause the information concerning the position of the handle and the rod relative to one another to be transmitted to the driving device in question via a connection 156 attached to the sensors 112, 113, said connection in the example illustrated constituting the female component of a contact.
- the signals from the sensors are first buffered by means of a high—impedance operational amplifier, since the sensor is capacitive.
- the signals are then mixed to produce a signal with a polarity corresponding to the direction of the force.
- the polarity of this signal also controls two analogue switches in such a way that the sensor which is not active is 'short—circuited'. This prevents the sensor from 'driving*.
- the signal then supplies a P—I stage which provides the ramp function, and the P component is necessary in order to eliminate any self-oscillations.
- the output signal from the P—I stage controls three phase control circuits, one for each phase, which control the torque.
